technical field

The utility model relates to a sanitary washing device.

Background technique

In the past, the sanitary washing device has a variety of spray modes of washing water sprayed from predetermined nozzles to the user's local area, and various washing water can be appropriately selected according to the user's preference through predetermined operating elements. any of the spray modes available.

In addition, in recent years, sanitation washing apparatuses have been equipped with various functions in addition to the above-mentioned discharge mode selection function, and it is necessary to prepare an operation member for each mounted function at an operation place such as a side wing. However, due to the restriction of the space at the operating place and the miniaturization requirements of the operating place, it is difficult to configure a large number of operating parts. Therefore, a sanitary washing device that can select multiple functions through one operating part has been proposed (for example, refer to Patent Document 1 ).

In addition, in the sanitary washing device disclosed in Patent Document 1, the boost switch for transitioning the washing operation from the normal washing operation to the turbo washing operation is combined with the local washing switch for starting the normal washing operation. . Specifically, the sanitary cleaning device of Patent Document 1 controls the local cleaning mechanism in the following manner: when the local cleaning switch is turned on when the condition for performing the local cleaning operation is satisfied, if the local cleaning is not performed In the state of the cleaning operation, the partial cleaning operation is started, and if it is in the state of performing the normal cleaning operation as the partial cleaning operation, the normal cleaning operation is transitioned to the enhanced cleaning operation. In addition, if the intensive cleaning operation is being performed as the partial cleaning operation, the intensive cleaning operation will continue as long as the partial cleaning switch is kept on.

Patent Document 1: Japanese Patent Application Laid-Open No. 8-144350

However, in the sanitary washing device disclosed in Patent Document 1, in order to perform the intensive washing operation, it is necessary to perform the normal washing operation. In the case of this conventional example, since the normal cleaning operation is usually required, no problem generally occurs. However, in the case where three or more washing water spray modes are switched by one operation member, there may be a problem that the user has to feel the washing water spray mode which is currently undesirable for the user.

For example, imagine the following structure: In the sanitary washing device disclosed in Patent Document 1, in addition to the normal washing action and the enhanced washing action, there is also a wide-angle spray of washing water from the nozzle opening and gentle cleaning. The wide-width cleaning action for local cleaning, and can be switched in the order of normal cleaning action, enhanced cleaning action, and wide-width cleaning action through the local cleaning switch.

In this structure, when the user feels, for example, "the current normal cleansing action is very stimulating, so I want to switch to the wide cleansing action that gently cleans the buttocks", if the user does not operate the partial cleansing switch twice and feels halfway If the enhanced washing action is not available, the transition from the normal washing action to the wide-width washing action cannot be performed. That is to say, although the user has performed the operation of transitioning to a wide-width cleaning action because of the strong stimulation of the usual cleaning action, it is still necessary to feel the strengthening of the cleaning action stronger than the usual cleaning action stimulation, thereby will feel inconvenient.

In addition, when the user feels that "the current wide cleaning action is not stimulating enough, so I want to switch to a stronger washing action that stimulates more", or feels that "the current enhanced washing action is too stimulating, so I want to switch to it." The same is true in the case of "switching to the normal cleaning operation", and it is inconvenient to feel the current unwanted cleaning operation.

The toilet seat main body 200 has a communication interface 202 and a seating detector 610 . Moreover, the body washing nozzle 840, the washing water supply mechanism 204, and the nozzle driving mechanism 206 are provided in the toilet seat main body part 200. As shown in FIG. In addition, the mechanism comprised from the body washing nozzle 840, the washing water supply mechanism 204, and the nozzle drive mechanism 206 shows embodiment of the washing fluid ejection mechanism concerning this invention. Moreover, the toilet seat main body part 200 incorporates the control part 90 which performs the overall control of the sanitary washing apparatus 100 based on the signal which the remote control device 300 and the seating detector 610 transmit.

The communication interface 202 is an interface for communicating between the toilet seat main body 200 and the remote control device 300 .

The seating detector 610 is provided on the front upper part of the toilet seat main body part 200 . In this embodiment, the seat detector 610 adopts a reflective infrared sensor. When an infrared sensor is used, when a user sits on a toilet seat, the receiving level (level) of the infrared rays reflected by the user's body is detected, and the user's sitting is detected.

In addition, the seating detector 610 may use a micro switch, an electrostatic capacitor, or an ultrasonic sensor in addition to an infrared sensor. In the case of employing the microswitch, the sitting of the user is detected based on the weight of the user when sitting on the toilet seat. In the case of a configuration in which a micro switch is buried in the leg part of the support part of the toilet seat and the toilet seat rotation shaft, and it is turned on (ON)/off (OFF) according to the load, or in the case of using an electrostatic capacitor, when using When the user sits on the toilet seat, the electrostatic capacitance formed by the aluminum sheet arranged inside the toilet seat and the floor surface of the toilet changes. Therefore, it is also possible to adopt a structure that detects the sitting of the user by detecting the variation range of the electrostatic capacitance. When the ultrasonic sensor is used, for example, the ultrasonic sensor provided on the main body and the remote control unit detects ultrasonic waves reflected by the user's body when the user sits on the toilet seat, thereby detecting the user's sitting.

The body washing nozzle 840 is a nozzle that sprays washing water (warm water) to the body part of the user after defecation, and is provided at the front lower portion of the toilet seat main body 200 . The body washing nozzle 840 includes a buttock washing nozzle, a feminine washing nozzle, and the like. In addition, the body washing nozzle 840 has mechanisms respectively corresponding to a buttock washing mode, a wide washing mode, and an air bubble washing mode which will be described later.

In the present embodiment, the body washing nozzle 840 has two flow paths inside the tube, and these two flow paths merge just before spraying from the spray hole at the end. Of these two flow paths, one is a straight flow path (refer to reference numeral 851 in FIG. A swirling flow path (refer to reference numeral 852 in FIG. 3 ) provided eccentrically with respect to the shaft center in such a way that clean water flows in a direction rotating around the straight direction of the straight flow path and merges. By controlling the flow rate ratio of the washing water flowing through these two flow paths, the shape of the jet stream sprayed from the nozzle 20 can be changed.

If the flow rate ratio of the washing water in the direct flow path of the two flow paths is high, the cleansing water with a strong straight-flow force is sprayed from the body washing nozzle 840 . This spraying method of washing water is called "rear washing mode (or direct injection mode)".

By increasing the flow rate ratio of the washing water in the swirling flow path among these two flow paths, when the washing water to which a rotational force is given after joining flows is sprayed from the spray hole, it can be sprayed in a swirling flow and become Wide jet shape. This spraying method of washing water is called "wide washing mode (or wide mode)".

An air pump (refer to reference numeral 14 in FIG. 3 ) is provided on the toilet seat main body 200, and by forcibly mixing air into the washing water, it can become a jet flow that can further improve the washing power, thus forming a water jet toward the body washing nozzle 840. The structure in which the air blown out from the air pump is mixed in the middle of the flowing channel and sprayed out from the spray hole. The spraying method of such washing water mixed with air in the jet flow of the buttock washing mode is called "bubble washing mode (or air mode)".

The cleansing water supply mechanism 204 is a mechanism for supplying cleansing water to the body washing nozzle 840, and includes a water pipe, a control valve provided in the water pipe, and the like. In addition, the washing water supply mechanism 204 heats the washing water supplied from the tap water pipe into warm water by a heating mechanism not shown, and then supplies it to the body washing nozzle 840 and the like.

The nozzle driving mechanism 206 is a mechanism for driving the body washing nozzle 840, and includes a motor, a rack, a pinion, and the like. Body washing nozzle 840 is configured to advance and retreat within a distance from a predetermined initial position to a washing water jetting position by nozzle driving mechanism 206 .

Moreover, although not shown in figure, the toilet nozzle which sprays the flush water toward the inner surface of the toilet 700 is provided in the front lower part of the toilet seat main body part 200. As shown in FIG. In the case of the toilet pre-wash mode, flush water is sprayed from the toilet nozzle to a wide range of the inner surface of the toilet 700 . In the case of the toilet rear flushing mode, flush water is sprayed from the toilet nozzle to the rear surface side of the inner surface of the toilet 700 .

The control unit 90 is constituted by, for example, a microcomputer and its peripheral circuits. In the present invention, a control unit means not only a single control unit but also a control unit group composed of a plurality of control units. Therefore, the control unit 90 may be configured to be controlled centrally by a single control unit, or may be configured to be controlled in a distributed manner by a plurality of control units working in cooperation. When it is detected by the seating detector 610 that the user has sat down on the toilet seat part 400, the control part 90 controls so that predetermined operation|movement linked|linked with the detection of this seating is performed. In addition, the predetermined actions include, for example: the buttocks of the user's part sprayed with cleansing water through the body washing nozzle 840, and the washing action for women; ; the drying action of partially drying the wet after washing; the sterilizing action of sterilizing the inside of the body washing nozzle 840 and the flow path of the washing water supply mechanism 206; and the toilet 700 through a predetermined filter The deodorization operation etc. which deodorize the internal odor.

In addition, when the user operates a predetermined operation element provided on the remote control device 300 , the control unit 90 controls such that a predetermined operation corresponding to the operation of the predetermined operation element is performed.

The remote control device 300 is a device for remotely controlling the toilet seat main body 200 , and the remote control device 300 is installed in a place where a user seated on the toilet seat 400 can operate. Functions that can be operated by the user through the remote control device 300 will be described later.

[Structure of the washing water supply mechanism and the nozzle driving mechanism of the toilet seat body]

The channel switching valve 13 has a plurality of ports. The straight-forward flow path 851 of the body washing nozzle 840 , the swirl flow path 852 , the feminine flow path 853 , and the nozzle cleansing nozzle 820 are respectively connected to a plurality of ports of the flow path switching valve 13 . The air pump 14 is connected between hoses h6 and h7 , which will be described later, connecting the flow path switching valve 13 and the straight flow path 851 of the nozzle device 800 . The vacuum breaker 31 is connected to the branch pipe 30 extending from the part of the pipe 3 between the water shutoff solenoid valve 7 and the flow sensor 8 , and the vacuum breaker 31 is arranged at the outlet of the washing water from the heat exchanger 9 . The port is located at the top. The vacuum breaker 31 is connected to one end of a branch pipe 32 . The branch piping 30 and the branch piping 32 are connected via a vacuum breaker 31 . The other end of the branch pipe 32 is configured to discharge water into the toilet, for example.

The vacuum breaker 61 is provided in the buffer tank 12 and arranged above the heat exchanger 9 . In addition, since the vacuum circuit breaker 61 and the buffer tank 12 are integrally formed, the buffer tank 12 is also arranged above the heat exchanger 9 .

Next, the flow of the washing water in the toilet seat main body part 200 and the control of each component part of the toilet seat main body part 200 by the control part 90 are demonstrated.

The clean water flowing through the water pipe 1 is supplied to the filter 4 through the branch valve plug 2 as the washing water. Thus, dust (gomi) and impurities contained in the washing water are removed by the filter 4 . Next, the backflow of the washing water in the piping 3 is prevented by the check valve 5 , and the flow rate of the washing water flowing in the piping 3 is maintained constant by the constant flow valve 6 . Then, the supply state of the washing water to the heat exchanger 9 is switched by the water shutoff solenoid valve 7 . The action of the water cutoff solenoid valve 7 is controlled by the control unit 90 .

The thermistor TH1 measures the temperature of the washing water flowing through the pipe 3 , and supplies the measured temperature value to the control unit 90 . The flow sensor 8 measures the flow rate of the washing water flowing through the pipe 3 and supplies the measured flow value to the control unit 90 . The heat exchanger 9 heats the washing water supplied through the pipe 3 to a set temperature.

Next, the water pump 11 heats the washing water heated by the heat exchanger 9 and supplies it to the channel switching valve 13 of the nozzle device 800 through the buffer tank 12 . The thermistor TH2 measures the temperature of the washing water flowing through the pipe 10 , and supplies the measured temperature value to the control unit 90 . The operations of the heat exchanger 9 and the water pump 11 are controlled by the control unit 90 based on the flow value measured by the flow sensor 8 and the temperature values measured by the thermistors TH1 and TH2. In addition, the buffer tank 12 functions as a temperature buffer of the heated washing water. This suppresses the occurrence of temperature unevenness in the washing water supplied to the channel switching valve 13 .

The body washing nozzle 840 is used for washing the user's local area, and the nozzle washing nozzle 820 is used for washing the sprayed portion of the washing water from the body washing nozzle 840 .

The flow path switching valve 13 of the nozzle device 800 selectively supplies the washing water supplied from the water pump 11 to the body washing nozzle 840 or the nozzle washing nozzle 820 by the operation of the switching valve motor 13m. As a result, washing water is sprayed from body washing nozzle 840 or nozzle washing nozzle 820 . The operation of the switching valve motor 13m is controlled by the control unit 90 .

When the washing water from the water pump 11 is supplied to the straight flow path 851 of the body washing nozzle 840, when the user operates the rear water flow switch 327 (see FIGS. 6A and 6B ) to select the bubble washing mode, The air pump 14 operates. As a result, the air pump 14 mixes air into the washing water flowing from the flow channel switching valve 13 to the straight flow channel 851 , and the nozzle device 800 intermittently spouts water clusters of the washing water to be described later.

The rest of the flush water supplied from the shutoff electromagnetic valve 7 to the heat exchanger 9 and not used in the nozzle device 800 flows into the toilet as waste water through the branch pipe 30 and the branch pipe 32. That is, the branch piping 30 and the branch piping 32 function as a waste water circuit.

In addition, a vacuum interrupter 31 is provided on the upstream side of the heat exchanger 9 , and a vacuum interrupter 61 is provided on the downstream side of the heat exchanger 9 . With these structures, when a negative pressure is formed in the pipe 3 or the pipe 10, the leakage of washing water from the heat exchanger 9 is prevented. As a result, empty firing of the heat exchanger 9 is prevented.

[Switching operation of the cleaning mode of the sanitary cleaning device]

Fig. 8 is a state transition diagram for explaining the switching operation of the washing mode of the sanitary washing device according to Embodiment 1 of the present invention.

In Fig. 8, S0 represents the state of selecting and executing the buttock washing mode, S1 represents the state of selecting and executing the wide width washing mode, S2 represents the state of selecting and executing the air bubble washing mode, and S3 means washing the selected air bubbles The state (standby mode) in which the execution of the mode is waiting. In addition, the standby mode S3 set between the wide washing mode ( S1 ) and the bubble washing mode ( S2 ) represents an embodiment of the standby state during conditional execution according to the present invention.

In addition, a solid line with an arrow connecting each state indicates that the state changes in the direction of the arrow. In addition, for a sentence expressed in the form of "○/△" by appending a solid line with an arrow, "○" indicates an action (input) for performing a state change, and "△" indicates an action (input) as a result of the "○" action. The event (output) that was raised. For example, for a statement expressed by "switch pressed/standby", "switch pressed" indicates an action (input) used to make a state change, and "standby" indicates an action raised as a result of the action "switch pressed" event(output).

Firstly, when the buttock washing mode is executed in state S0 , when the rear end water flow switch 327 is pressed, the buttock washing mode is switched from state S0 to wide washing mode S1 without delay. At this time, the operation of the nozzle device 800 is to switch from the state where the water supply port 131 communicates only with the straight-in discharge port 135 to the state where the water supply port 131 communicates with the straight-in spray port 13 in the flow path switching valve 13 by operating the switching valve motor 13m. The outlet port 135 and the swirl outlet port 133 are in communication. In addition, at this time, the user can visually grasp that the rear end washing mode has been switched to the wide washing mode by lighting the wide washing mode display unit 238 .

Next, when the rear water flow switch 327 is pressed in the state S1 in which the wide-width washing mode is executed, the state S1 in which the wide-width washing mode is executed transitions to the standby mode S3 in which the execution of the bubble washing mode is on standby. That is to say, even if the buttocks water flow switch 327 is pressed, it does not immediately switch from the state S1 in which the wide-width washing mode is executed to the state S2 in which the bubble washing mode is executed. At this time, the operation of the nozzle device 800 is such that the water supply port 131 continues to communicate with the straight discharge port 135 and the swivel discharge port 133 in the flow channel switching valve 13 . In addition, when the buttock water flow switch 327 is pressed, the wide washing mode display part 238 is turned off and the air bubble washing mode display part 239 is turned on, so that the user can visually grasp the buttock water flow switch 327. The press itself has been executed normally for this case.

Next, in the standby mode S3, if the buttocks water flow switch 327 is pressed again (continuously pressed) during the predetermined time T1 after the buttocks water flow switch 327 is pressed, then after a predetermined period of time has elapsed since the button was pressed again. After time T1, the standby mode S3 transitions to the state S0 in which the buttock washing mode is executed without passing through the state S2 in which the bubble washing mode is executed. At this time, as the operation of the nozzle device 800, the switching valve motor 13m is operated, and in the flow path switching valve 13, the water supply port 131 is switched from the state in which the water supply port 131 communicates with the straight-forward discharge port 135 and the swivel discharge port 133 to the water supply state. A state where the port 131 communicates only with the straight-in discharge port 135 . In addition, by continuously pressing the buttocks water flow switch 327, the wide-width washing mode display part 238 and the bubble washing mode display part 239 are turned off, so that the user can visually grasp that the bubble washing mode has been switched to the rear washing mode. mode in this case.

On the other hand, in the standby mode S3, if the buttocks water flow switch 327 is not pressed again during the predetermined time T1 after pressing the buttocks water flow switch 327 (continuous press), the transition from the standby mode S3 to the execution of the air bubble The state S2 of the washing mode.

Next, when the buttocks water flow switch 327 is pressed in the state S2 of the air bubble washing mode, the state S2 of the air bubble washing mode is switched to the state S0 of the buttock washing mode without delay. At this time, the operation of the nozzle device 800 is to switch from the state in which the water supply port 131 communicates with the straight-forward discharge port 135 and the swivel discharge port 133 in the flow path switching valve 13 to the state of communicating with the flow path switching valve 13 by the switching valve motor 13m. The straight-in discharge port 135 is connected, and air is mixed from the air pump 14 into the washing water flowing in the straight-in flow path 851 . In addition, at this time, by turning off the lights of the wide washing mode display unit 238 and the bubble washing mode display unit 239 , the user can visually recognize that the air washing mode has been switched to the buttock washing mode.

9A and 9B are diagrams for explaining an example of the switching operation of the washing mode according to Embodiment 1 of the present invention based on the state transition diagram shown in FIG. 8 .

In the example shown in FIG. 9A , the state S1 is in which the wide washing mode is executed before time t0 . In addition, when the buttock water flow switch 327 is pressed at time t0, the state S1 in which the wide-width washing mode is executed transitions to the standby mode S3. Then, at time t2 after a predetermined time T1 elapses from time t0 , the standby mode S3 transitions to the state S2 in which the air bubble cleaning mode is executed.

In the example shown in FIG. 9B , as in FIG. 9A , the state S1 in which the wide-width cleaning mode is executed is before time t0. In addition, when the buttock water flow switch 327 is pressed at time t0, the state S1 in which the wide washing mode is executed transitions to the standby mode S3. Then, at time t1 within the predetermined time T1 from time t0 to time t2, if the buttock water flow switch 327 is pressed again (consecutively pressed), the standby mode S3 continues even after time t2 passes. That is, switching from the wide washing mode to the bubble washing mode is not performed. Then, at time t3 after the predetermined time T1 has elapsed since the buttock water flow switch 327 was pressed again, the state S0 in which the buttock washing mode is executed is transitioned from the standby mode S3.

The aforementioned switching operation is, for example, when the user feels that "the buttocks are widely wet in the current wide-width washing mode, so they want to switch to the default buttock washing mode". At this time, by pressing the buttocks water flow switch 327 twice within a predetermined period of time, it is possible to switch from the state S1 in the wide-width washing mode to the state S0 in the buttocks washing mode without feeling the bubble washing mode. That is to say, when the user switches from the wide-width washing mode to the buttock washing mode by manipulating the buttock water flow switch 327, the inconvenience of the bubble washing mode with strong somatosensory stimulation is avoided. In addition, since switching to the air bubble washing mode is not performed during switching from the wide washing mode to the rear washing mode, the life of the air pump 14 can be extended without unnecessary driving of the air pump 14 .

[modified example]

In the above-mentioned embodiment, the situation that the buttock water flow switch 327, the wide washing mode display part 328 and the air bubble washing mode display part 329 are provided on the remote control device 300 as shown in Fig. 6A and Fig. 6B has been described, but it may also be 10. As shown in FIG. 11 , in the sanitary washing device 100 provided with a side wing portion 250 , the side wing portion 250 is provided with the buttock water flow switch 254 and the wide washing mode display portion 255 as shown in FIGS. 6A and 6B . And the bubble cleaning mode display part 256. That is to say, one operating member according to the present invention may be arranged at a position where the user can easily operate when sitting on the toilet seat 400 .

In addition, in the above-mentioned embodiment, it has been described that the washing water is used as the washing fluid related to the present invention, and the switch such as the buttocks water flow switch 327 is used as an example of an operating member related to the present invention, but the present invention It is not limited to this. For example, an embodiment of a knob operated by the user such as the knob of the toilet flushing switch 336 may be adopted.

In addition, for example, a configuration may be adopted in which the three spray modes are switched by the rear switch 312 for selecting the case where the washing water is sprayed toward the user's rear. That is to say, it may also be configured as follows: the spray pattern from the body washing nozzle 840 is determined by the operation of the hip switch 312, and then the cleansing water of the determined spray pattern is sprayed to the user's body. partial.

In addition, in the above-mentioned embodiment, the case where the buttocks washing mode, the wide washing mode, and the air bubble washing mode are cycled and switched every time the buttocks water flow switch 327 is pressed has been described, but the switching between the three washing modes The order is not limited to the above order. For example, each time the buttocks water flow switch 327 is pressed, the buttocks washing mode, air bubble washing mode, and wide washing mode may be cycled and switched in order.

In addition, in the above-mentioned embodiment, three types of washing water spray modes that are switched every time the rear water flow switch 327 is pressed are exemplified, including the buttock washing mode, the air bubble washing mode, and the wide washing mode, but it is not limited to The jetting patterns of these wash waters may be any jetting patterns of the washing water that differ in the user's bodily sensation. For example, the following modes can also be used as the object of conditional execution related to the present invention: the jetting mode (spiral washing mode) in which cleansing water swirls in a spiral form from the jet outlet of the body washing nozzle 840, washing The spray mode (rhythmic cleansing mode) in which water is sprayed from the discharge port of the body washing nozzle 840 in a manner that rhythmically makes the flow rate per unit time variable, and the body washing nozzle 840 advances and retreats from the discharge port. Spray mode (mobile washing mode) for spraying washing water, etc.

In this embodiment, a plurality of washing modes can be realized with one body washing nozzle 840, but it is not limited to this structure, and it is also possible to have a plurality of nozzles with different washing methods and use a plurality of nozzles respectively to change The structure of the schema. In addition, the realization of the above-mentioned each cleaning mode is not limited to the above-mentioned structure, for example, the "wide cleaning mode" that can obtain a soft cleaning feeling may be realized by changing the method of mixing air into a natural suction method. structure.

In addition, in the above-mentioned embodiment, the standby mode S3 is set when the execution (S1) of the wide-width cleaning mode is switched to the execution (S2) of the air bubble cleaning mode (the implementation of the conditional execution involved in the present invention) mode), but it is also possible to set a standby mode equivalent to the standby mode S3 when switching from the execution (S0) of the buttock washing mode to the execution (S1) of the wide washing mode. In this case, for example, the user feels that "the current buttock washing mode is not stimulating enough, so he wants to switch to the more stimulating air bubble washing mode". At this time, by pressing the buttocks water flow switch 327 twice within a predetermined time, it is possible to switch from the state S0 in the buttocks washing mode to the state S2 in the bubble washing mode without feeling the wide washing mode. That is to say, when the user operates the buttocks water flow switch 327 to switch from the buttocks washing mode to the air bubble washing mode, the inconvenience of the wide washing mode in which the user feels that the buttocks are wetted in a large area is avoided. . In addition, since the switch from the buttocks washing mode to the air bubble washing mode is not switched to the wide washing mode, in the flow path switching valve 13, the communication between the water supply port 131 and the straight inlet and outlet port 135 is maintained. state. That is, there is no need to drive the switching valve motor 13m, and it is not necessary to rotate the flow path switching valve 13 uselessly.

Moreover, when switching from execution (S2) of the bubble washing mode to execution (S0) of the buttock washing mode, you may provide the standby mode equivalent to standby mode S3. In this case, for example, the user feels that "the current bubble cleansing mode is too irritating, so he wants to switch to the wide-width cleansing mode that is gentle on the buttocks." At this time, by pressing the buttocks water flow switch 327 twice in a predetermined period of time, it is possible to switch from the state S2 performing the bubble washing mode to the state S1 performing the wide-width washing mode without feeling the buttocks washing mode. That is to say, when the user wants to switch from the bubble washing mode to the wide washing mode, the user operates the buttocks water flow switch 327 to avoid the inconvenience of the user feeling the buttocks washing mode. In addition, since the rear washing mode is not switched to the rear washing mode during switching from the bubble washing mode to the wide washing mode, it is possible to stop the air from the air pump 14 from being mixed into the straight flow path 851, and the flow path switching valve 13 The water supply port 131 communicates with the straight-forward jetting port 135 and the swivel jetting port 133 , and can quickly transition from the bubble washing mode to the wide-width washing mode.

In addition, as an example of switching the spray modes of at least three cleansing fluids with different physical sensations by one operation element, at least three drying modes with different physical sensations using air as the cleansing fluid may be targeted. For example, the default normal drying mode and the air volume per unit time can be compared with the drying wind in the normal drying mode like the above-mentioned buttock washing mode, air bubble washing mode and wide washing mode in the case of using water as the washing fluid. The strong enhanced drying mode and the wide drying mode that sprays drying wind at a wider angle than the normal drying mode are targeted. In addition, when the body cleansing nozzle 840 is a common cleansing and drying nozzle that sprays cleansing water and also sprays warm air that dries the user's part, at least three types of body washes with different physical sensations can be used with one operating part. The sanitary cleansing device according to the present invention which is the object of the dry mode can be realized by the same structure and operation as the sanitary cleansing device 100 .

As mentioned above, the case where three or more modes are changed for washing and drying has been described, but it is not limited to this. For the setting of the toilet seat temperature of the heated toilet seat that can be heated at a high speed, a so-called instantaneous heat exchange is installed. The setting of the warm water temperature of the warm water toilet seat of the appliance, etc. can also be used as a control method when changing their modes. As long as these instantaneous heated toilet seats or instantaneous heat exchangers are used, the toilet seat temperature or the warm water temperature can be changed immediately in response to a mode change operation. Thus, the body directly senses this temperature change. Also in this case, by appropriately setting the standby mode, it is possible to realize a comfortable sanitary washing device that does not spoil the user's usability. In addition, compared with merely providing switches corresponding to various modes, it is possible to effectively use limited operating portion areas and components.

In addition, as one of the three or more modes, it is conceivable to include a setting of "OFF". For example, the water temperature adjustment switch 332 and the toilet seat temperature adjustment switch 333 are also applicable to the present utility model, and the water temperature adjustment switch 332 switches the temperature of the washing water locally sprayed to the user to include "off" and is set at 4 grades ("high temperature", "medium temperature", "low temperature" and "off"), the toilet seat temperature adjustment switch 333 switches the temperature of the toilet seat part 400 to include the "off" setting. 4 levels ("High", "Medium", "Low" and "Off"). For example, when the sanitary washing device 100 has the function of instantaneously heating the toilet seat or instantaneously exchanging heat, the temperature of the washing water or the temperature of the toilet seat part 400 is instantaneously switched by the water temperature adjustment switch 332 or the toilet seat temperature adjustment switch 333. Those who are prone to feel the sudden change in temperature. Here, when operating the water temperature adjustment switch 332 or the toilet seat temperature adjustment switch 333 to switch from the "high" setting to the "off" setting, the user will suddenly feel the discomfort of the temperature becoming cold. Therefore, when the conditional execution involved in the present invention is applied to the operation of the water temperature adjustment switch 332 or the toilet seat temperature adjustment switch 333, for example, by operating the water temperature adjustment switch 332 or the toilet seat temperature adjustment switch 333 twice within a predetermined time Therefore, the temperature of the washing water or the temperature of the toilet seat 400 can be switched from the state of the "high" setting to the state of the "low" setting without the user feeling the state of the "off" setting, There will be no unpleasant feeling of sudden temperature changes.

In addition, in the present embodiment, the instantaneous type heat exchanger 9 has been described, but as long as washing water is supplied to a nozzle device having a mechanism for ejecting a plurality of washing fluids having different physical sensations, any heat exchanger 9 may be provided. A hot water storage type tank is used to supply warm water, and hot water and water are mixed to adjust the temperature to an appropriate temperature to supply warm water.

Fig. 12 is a state transition diagram for explaining the switching operation of the washing mode in the sanitary washing apparatus according to Embodiment 2 of the present invention. The difference from the state transition diagram according to Embodiment 1 of the present invention shown in FIG. And during switching from the state S0 of performing the buttock washing mode to the state S1 of performing the wide-width washing mode, and during the period of switching from the state S2 of performing the air bubble washing mode to the state S0 of performing the buttock washing mode, also set There is the same standby mode as standby mode S3.

First, when the buttocks water flow switch 327 is pressed in the state S0 in which the buttock washing mode is executed, the state S0 in which the buttocks washing mode is executed transitions to the standby mode S5. The standby mode S5 is a mode in which the execution of the selected wide washing mode is held on standby. In addition, the user can recognize that the rear end washing mode has been switched to the wide washing mode by lighting the wide washing mode display unit 238 .

In the standby mode S5, if the buttock water flow switch 327 is pressed again (continuously pressed) during a predetermined time T1 after the buttock water flow switch 327 is pressed, the standby mode S5 transitions to the standby mode S3. The standby mode S3 is a mode for waiting for selection of the selected bubble washing mode. In addition, by continuously pressing the buttock water flow switch 327, the wide washing mode display part 238 is turned off, and the air bubble washing mode display part 239 is turned on, so that the user can grasp that the pressing of the buttock water flow switch 327 itself has been performed normally. This situation.

On the other hand, in the standby mode S5, if the buttocks water flow switch 327 is not pressed again (consecutively pressed) before the predetermined time T1 has elapsed after the buttocks water flow switch 327 is pressed, then after the buttocks water flow switch 327 has been pressed, the time has elapsed. At a predetermined time T1, the standby mode S5 transitions to the state S1 in which the wide-width washing mode is executed.

Next, when the rear end water flow switch 327 is pressed in the state S1 in which the wide washing mode is executed, the state S1 in which the wide washing mode is executed transitions to the standby mode S3. In addition, when the buttock water flow switch 327 is pressed, the wide washing mode display part 238 is turned off, and the bubble washing mode display part 239 is turned on. Thereby, the user can grasp that the pressing itself of the buttocks water flow switch 327 has been performed normally.

In the standby mode S3, if the buttock water flow switch 327 is pressed again (consecutively pressed) before the predetermined time T1 elapses after the buttock water flow switch 327 is pressed, the standby mode S3 transitions to the standby mode S4. In addition, by repeatedly pressing the buttock water flow switch 327, the wide washing mode display part 238 and the air bubble washing mode display part 239 are turned off, so that the user can grasp that the pressing of the buttock water flow switch 327 itself has been normally performed. Condition.

On the other hand, in the standby mode S3, if the buttocks water flow switch 327 is not pressed again (continuously pressed) before the predetermined time T1 has elapsed after pressing the buttocks water flow switch 327, then the predetermined time has elapsed after pressing the buttocks water flow switch 327. During the time T1, the standby mode S3 transitions to the state S2 in which the air bubble cleaning mode is executed.

Next, when the buttock water flow switch 327 is pressed in the state S2 in which the air bubble washing mode is being executed, the state S2 in which the air bubble washing mode is being executed transitions to the standby mode S4. The standby mode S4 is a mode for waiting for selection of the selected buttock washing mode. At this time, by turning off the lights of the wide washing mode display unit 238 and the bubble washing mode display unit 239 , the user can grasp that the air washing mode has been switched to the buttock washing mode.

In the standby mode S4, if the buttock water flow switch 327 is pressed again (consecutively pressed) before the predetermined time T1 elapses after pressing the buttock water flow switch 327, the standby mode S4 transitions to the standby mode S5. In addition, by continuously pressing the buttock water flow switch 327, only the wide washing mode display portion 238 lights up, whereby the user can grasp that the pressing of the buttock water flow switch 327 itself has been normally performed.

On the other hand, in the standby mode S4, if the buttocks water flow switch 327 is not pressed again (continuously pressed) during the period from pressing the buttocks water flow switch 327 to the elapse of a predetermined time T1, after the buttocks water flow switch 327 is pressed, When predetermined time T1 has passed, it transitions from standby mode S4 to state S0 in which the buttock washing mode is performed.

Through the above-mentioned switching operation, for example, when the user feels that "in the current buttock washing mode, the stimulation for washing is not enough, so he wants to switch to the bubble washing mode with strong stimulation and sufficient washing", It is possible to switch from the rear cleansing mode to the bubble cleansing mode without feeling wet in the wide cleansing mode. In addition, when the user feels that "the current bubble cleansing mode is too irritating, so he wants to switch to the wide cleansing mode that is gentle on the buttocks", it is possible to avoid feeling the unwanted buttocks cleansing mode , switch from bubble wash mode to wide wash mode.

[modified example]

In Embodiment 2 of this invention, the same modification as Embodiment 1 of this invention can be employ|adopted.

In addition, in Embodiments 1 and 2, the case where there are three types of washing modes (discharge modes) is illustrated, but the present invention is not limited thereto, and it is sufficient if there are two or more types of dispensing modes. For example, when the user switches from one spray mode to another spray mode by mistake through an operating part, through the conditional execution involved in the present utility model, it is possible to use the other spray mode without bodily feeling case returns to the one ejection mode.

Furthermore, in Embodiments 1 and 2, if the user does not select the next washing mode in the standby state (standby mode), the washing mode can be selected only unidirectionally (in a circuit). But the present invention is not limited thereto, and can also be configured as follows: if the user does not select the next washing mode in the standby state (standby mode), multiple washing modes can be selected in a predetermined order. For example, it is configured to select multiple cleaning modes back and forth, or to divide multiple cleaning modes into multiple groups, and to select multiple cleaning modes in each group only unidirectionally (in a roving manner) or back and forth. .

Based on the above description, many improvements or other implementations of the present utility model are obvious to those skilled in the art. Therefore, the above description should be interpreted as an illustration only, and it is provided for the purpose of teaching the best mode for carrying out this invention to those skilled in the art. Substantial changes may be made in details of construction and/or function without departing from the spirit of the invention.
