Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a private parts cleaning device, and particularly to a private parts cleaning device that can be suitably used in a unit bath in a hotel or the like.

(B) Conventional technology Conventionally, as a form of Western-style toilet, hot water and water are supplied from the outside, a thermostatic mixing valve generates a mixture of hot water and water at an appropriate temperature, and the mixed hot water is sent to a cleaning nozzle installed inside the toilet body. Some devices are equipped with a private parts cleaning device that can be used to clean private parts by discharging liquid from the inside.

When such a private part cleaning device generates mixed hot water,
There is no need to use an electric heater or electric hot water mixer that requires commercial power (100V AC), and the electromagnetic on-off valve that performs water discharging and water shutoff operations, as well as various sensors and control devices, are powered by dry batteries. This makes it possible to reliably prevent electric shock accidents and leakage accidents.

(c) Problems to be Solved by the Invention However, such private part cleaning devices still have the following problems that need to be solved.

That is, if a considerable amount of time passes after using the flush toilet until the next user uses the flush toilet, the temperature of the hot water in the hot water supply pipe decreases, resulting in a so-called dead water state.

Therefore, when the user presses the push-button switch for discharging water after sitting on the toilet seat, the thermostatic mixing valve mixes the hot water and the supplied water, and the mixed hot water generated is sprayed from the cleaning nozzle toward the private parts. However, since the hot water is supplied at a low temperature, the temperature of the mixed hot water is also inevitably low, causing discomfort to the user.

An object of the present invention is to provide a private part cleaning device that can solve the above problems.

(D) Means for Solving the Problems The present invention is configured to receive hot water and water from the outside, adjust the temperature to an appropriate temperature, and discharge the mixed hot water to the private area through a cleaning nozzle and stop the water supply through the user's operation. In the private part cleaning device, a thermostatic mixing valve is installed at the confluence of the hot water supply pipe and the water supply pipe, and a waste hot water pipe is branched from the hot water supply pipe, and a hot water temperature detection sensor and a waste hot water pipe are installed in the hot water supply pipe and the waste hot water pipe, respectively. An electromagnetic on-off valve is provided, and the electromagnetic on-off valve for waste hot water is driven to open by turning on a separately provided preliminary operation switch, and the electromagnetic on-off valve for waste hot water is opened by the hot water temperature detection output from the hot water temperature detection sensor. The present invention relates to a private part cleaning device characterized by the following.

Further, the present invention provides the above-mentioned private parts cleaning device, in which the hot water temperature detection sensor is turned on only when the preliminary operation switch is in the on state, and the hot water temperature is detected only once, and the preliminary operation switch is in the on state. Another feature is that the hot water temperature detection sensor is turned on only when it is in the on state, detects the hot water temperature only once, and then makes the hot water temperature detection sensor detect the hot water temperature again after a certain period of time has elapsed. It is.

(E) Functions and Effects According to the present invention, when using the toilet, for example, by turning on a preliminary operation switch such as a seating detection sensor, a toilet lid opening/closing operation detection switch, a door opening/closing operation detection switch, etc., the waste hot water can be opened and closed. By opening the valve, the low-temperature hot water (dead water) in the hot water pipe can be quickly discarded through the hot water pipe, and if the hot water temperature detected by the hot water temperature detection sensor exceeds the set temperature, The initial operation for spouting water at an appropriate temperature can be completed by closing the waste hot water electromagnetic on-off valve and stopping the waste hot water operation.

Thereafter, for example, by pressing a water spouting push button switch to start a cleaning operation, mixed hot water and water at an appropriate temperature can be spouted from the cleaning nozzle toward the private parts. Therefore, the user can relieve himself comfortably.

Furthermore, since the waste heating time can be minimized, it is also possible to save water and electricity.

Further, in the present invention, the hot water temperature detection sensor can be turned on only when the preliminary operation switch is in the on state, and the hot water temperature can be detected only once. In this case, the hot water temperature detection sensor can be turned on. The power required for operation can also be effectively saved.

Further, in the present invention, the hot water temperature detection sensor is turned on only when the preliminary operation switch is in the on state, and the hot water temperature is detected only once, and then, after a certain period of time has elapsed, the hot water temperature detection sensor is again set to the hot water temperature detection sensor. In this case, the power required to turn on the hot water temperature detection sensor can be saved, and, for example,
If you remain seated for a long time and the hot water temperature in the hot water supply pipe drops, the hot water temperature detection sensor can be turned on again and the hot water will be discarded. You can spray water towards.

Therefore, the user can relieve himself comfortably.

(F) Embodiment An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the conceptual overall structure of a private part cleaning device A according to the present invention.

As shown in the figure, hot water supply pipe 1 and water supply pipe 2, which have one end connected to a hot water supply source and a water supply source, respectively, have their other ends merged, and a thermostatic mixing pulp T that automatically controls the appropriate temperature is installed at the confluence point. has been established.

In the above configuration, the hot water supply pipe 1 and the water supply pipe 2 are provided with constant flow valves 3 and 4, respectively.

In addition, the hot water supply pipe 1 branches a waste hot water pipe 6 between the constant flow valve 3 and the thermostatic mixing pulp T,
An electromagnetic on-off valve V for waste hot water driven by a rafting trenoid is attached to the waste hot water pipe 6.

Furthermore, between the constant flow valve 3 and the branch part of the sacrificial hot water pipe 6,
The temperature of hot water flowing through the hot water pipe 1 is detected, and based on the ON output generated when the hot water temperature exceeds the set temperature,
A hot water supply temperature detection sensor S, which is made of a thermistor or the like, is installed, which can close the waste hot water electromagnetic on-off valve v1 and stop the waste hot water operation.

Next, to explain the configuration of the downstream side of the thermostatic mixing pulp T, the discharge port of the valve T is a water discharging electromagnetic on-off valve Vt driven by a rafting turenoid, similar to the above-mentioned electromagnetic on-off valve V for discarded hot water. It is connected to a cleaning nozzle N disposed inside the flush toilet B via a mixed hot water flow path M equipped with a water bath.

In addition, the mixed hot water flow path M is equipped with a high temperature spouting water detection sensor St consisting of a thermistor or the like that detects the mixed hot water temperature on the upstream side of the electromagnetic on-off valve V.
! As will be described later, high-temperature water discharge can be quickly detected based on the detection output, and the water discharge electromagnetic on-off valve Vt can be stopped based on the detection output.

Furthermore, in FIG. 1, the flush toilet B has a reflective seating detection sensor 41 that uses ultrasonic waves or infrared rays to detect when the user is sitting on the toilet seat, and a water spouting sensor 41 for discharging water from the private parts cleaning device A. Discharge push button switch 4 that drives the electromagnetic on-off valve Vt to discharge cleaning water from the cleaning nozzle N.
2 is installed.

In the above configuration, the seating detection sensor 41 functions as a preliminary operation switch, and opens the electromagnetic on-off valve for waste hot water based on the detection output generated when the user is seated, as described later. As a result, the low-temperature hot water (dead water) in the hot water pipe l can be quickly discarded through the hot water pipe 6, and the discarded hot water electromagnetic on-off valve v1 is activated by the set hot water temperature detection output from the hot water temperature detection sensor S.
The present invention relates to a private parts cleaning device characterized by driving the body closed.

The preliminary operation switch is not limited to the seating detection sensor 41, for example, a toilet lid opening/closing operation detection switch that detects the opening/closing operation of the toilet lid of flush toilet B, or a toilet lid opening/closing operation detection switch that detects the opening/closing operation of the toilet door. It can also be used as a door opening/closing operation detection switch.

Further, instead of the reflective seating detection sensor 41 as the preliminary operation switch, other non-contact sensors, microswitches, limit switches, load cells, or other seating detection means may be used.

Next, each component in the above basic configuration will be explained in detail. As shown in FIGS. 2 to 5, each constant flow valve 3.4 includes a housing 10 that is inserted into the flow path 9, It consists of a core member 11 mounted within the housing 10 and an O-ring 12 made of an elastic material.

Further, the housing 10 is formed in a cylindrical shape, and has a stepped portion 13 for hanging the core member 11 at the open end on the upstream side when inserted into the hot water supply pipe 1 and the water supply pipe 2, and has a stepped portion 13 for hanging the core member 11 on the downstream side. The opening end has a stepped portion 14 for hanging an O-ring.

The core member 11 is formed into a warhead shape and has a flange 16 having a water passage hole 15 at its rear end, and has a protrusion 17 extending in the axial direction on the circumferential surface, and the flange 16 and the housing l
It is hooked into the housing 10 by a step 13 for attaching the core of the O-ring, and the distal end thereof is loosely inserted into the inner periphery of the step 14 for attaching the O-ring and protrudes from the housing 10.

On the other hand, the O-ring 12 is loosely fitted between the inner circumferential surface of the housing 10 and the outer circumferential surface of the core member 11, and is hooked to the O-ring hooking stepped portion 14 of the housing 10.
This constant flow valve 3.4 is inserted into the flow path 9, and the water flowing through the flow path 9 passes through the water passage hole 15 and connects to the core member 11.
It flows through the gap 19 between the ring 12 and further through the gap 20 between the O-ring hanging step 14 and the core member 11 to the downstream side.

At this time, if the water supply pressure to the flow path 9 is low or in the normal case, as shown in FIGS. 2 and 3, the O-ring 1
2 is not deformed, and the gap 1 between the O ring 12 and the core member 11 is
9 maintains a predetermined water flow area, but when the water supply pressure increases, the O-ring 12 is pressed against the stepped portion 14 due to the pressure and is crushed and deformed, as shown in FIGS. 4 and 5. The water flow area of the gap 19 between the O-ring 12 and the core member 11 is reduced.

The deformation of the O-ring 12 increases as the water supply pressure increases, and accordingly, the water passage area decreases and the amount of water flow is restricted.

That is, this constant flow valve 3.4 always supplies a constant amount of water to the downstream side regardless of fluctuations in water supply pressure.

Next, the electromagnetic on-off valve V for waste hot water driven by rafting tureenoid
, and the configuration of the water discharge electromagnetic on-off valve v2 will be explained.

As shown in FIG. 6, each electromagnetic on-off valve V,, V□ has a solenoid 23 provided with a permanent magnet 22 for latching in an example of a diaphragm-type valve body 21.

To explain the operation of the electromagnetic on-off valves V, V, the solenoid 23 is energized in the forward or reverse direction to open and close the pilot valve body 26 that opens and closes the pilot valve seat 25 provided on the diaphragm 24, and the diaphragm The diaphragm 24 is actuated by the difference in water pressure acting on the front and back surfaces of the valve 24 to open and close the main valve seat 27, and the magnetic force of the permanent magnet 22 holds the pilot valve body 26 in the open or closed state. The main valve seat 27 can be maintained in the open/closed state by maintaining the water pressure difference between the two.

Therefore, in the electromagnetic on-off valves V,, V, using latching solenoids, the solenoid 23 drives only the pilot valve body 26, and the electromagnetic on-off valve Vll
Since it is necessary to energize only when opening/closing operation of V, power consumption is extremely small.

Next, the configuration of the thermostatic mixing valve T will be explained.

As shown in FIG. 7, the thermostatic mixing valve T has an inner cylinder 32, which has a mixing chamber 36 in the upper part and a valve body 31 in the lower part, inserted into the inside of a substantially cylindrical main body.
Insert a wax type thermostat 33 into the inside of 2, and attach the upper end of the thermostat 33 to the screw adjustment mechanism 34.
The thermostat 33 can be moved up and down by rotating the adjustment knob 35, and the lower part of the thermostat 33 filled with wax is connected to the inner cylinder 32.
The thermostat 33 is inserted into the mixing chamber 36 of the thermostat 33, and the middle part of the thermostat 33 is connected to the upper end of the inner cylinder 32.

With this configuration, the operation of the middle part of the thermostat 33 due to the expansion and contraction of the wax due to the temperature of the mixed hot water in the mixing chamber 36 is transmitted to the valve body 31 connected to the lower end of the inner cylinder 32, and the valve body 31 is provided above and below the valve body 31. By opening and closing the hot water and water valve seats 38 and 39 to change the mixing ratio of hot water flowing into the mixing chamber 36, the hot water flows from the mixing chamber 36 through the mixed hot water flow path M.
The temperature of the mixed hot water discharged from the cleaning nozzle N in the flush toilet bowl B is configured to match the temperature set by the adjustment knob 25.

In particular, since the thermostat 33 is operated based on the difference between the mixed hot water and the set temperature, a proportional control operation is performed, and there is no need to receive energy such as electric power from outside.

Next, the control device C that controls the driving of the private part cleaning device ifA having the above configuration will be explained with reference to the eighth article.

As shown in the figure, the control device WC is substantially connected to a comparator 43 that is connected to a hot water temperature detection sensor S1 and outputs an output when the hot water in the hot water supply pipe 1 reaches a predetermined temperature, and a high temperature water discharge detection sensor h. a comparator 44 that outputs an output when the temperature of the mixed hot water in the mixed hot water flow path M exceeds a high temperature limit temperature;
A logic circuit 45 in which the comparators 44 and 45, the seating detection sensor 41 and the discharge push button switch 42 are connected to the input part, and the output part of the logic circuit 45 and the above-mentioned electromagnetic on-off valve V for waste hot water.

And electromagnetic on-off valve for water discharge V! It is composed of drive circuits 46 and 47 interposed between the solenoids 23 and 23, a TFI battery, and a power switch 48.

In addition, FIG. 9 shows a timing chart of each drive unit and sensor, in which (a) is the operation time of the seating detection switch 41, (b) is the operation time of the water discharging push button switch 42, and (c) is the operation time of the water discharging push button switch 42. Operation time of hot water operation, (d) is a time chart showing changes in hot water supply temperature, (e) is operation time of cleaning operation, <1> is hot water supply temperature detection sensor S1
, (g) is the operation time of the electromagnetic on-off valve V1 for discarded hot water, and (h) is the electromagnetic on-off valve V for discharging water. operating time,
(10j) indicates the operation time (continuous operation and intermittent operation) of the high temperature discharge water temperature detection sensor S2.

When using this private part cleaning device A, the power switch 49
When the user puts in the water and sits on the toilet seat of the flush toilet B equipped with the private parts cleaning device A, the seating detection sensor 41 outputs an output, which is then output to the waste water layer tM1 on-off valve V via the logic circuit 45. The same electromagnetic on-off valve V is opened, and the hot water temperature detection sensor S
, maintains the valve open state until it detects a temperature sufficient to generate mixed hot water at an appropriate temperature, and discards the hot water whose temperature has decreased due to staying in the hot water supply pipe 1, discharging it through the hot water pipe 6, and adjusting the hot water temperature. When the detection sensor S detects a temperature equal to or higher than the set hot water supply temperature, the waste hot water electromagnetic on-off valve V is closed to stop the waste hot water operation.

Thereafter, when the discharge push button switch 42 is pressed by the user who has finished using the toilet, the discharge electromagnetic on-off valve V is opened, and the cleaning nozzle N in the toilet bowl B is opened via the thermostatic mixing valve T. The user can adjust the adjustment knob 3 from
Mixed hot water at the temperature set in step 5 will be discharged to cleanse your private parts.
When cleaning is completed, the electromagnetic on-off valve Vt for discharging water is closed to stop discharging water.

As described above, in this embodiment, by the initial operation of the seating detection sensor 41 as a preliminary operation switch, the low-temperature hot water (dead water) in the hot water supply pipe 1 can be quickly discarded through the hot water pipe 6, and the hot water When the temperature of the hot water detected by the temperature detection sensor Sr exceeds the set temperature, the waste hot water electromagnetic on-off valve v1 is driven to close and the waste hot water operation is stopped, thereby starting the initial operation for discharging water at an appropriate temperature. Thereafter, by pressing the water spouting push button switch 42, mixed hot water at an appropriate temperature can be spouted from the cleaning nozzle N toward the private parts.

Therefore, the user is freed from the discomfort caused by low-temperature water being sprayed onto the private parts when using the toilet, and can use the toilet comfortably at all times.

Furthermore, since the waste heating time can be minimized, it is also possible to save water and electricity.

Furthermore, the power required for the above-mentioned operation control is supplied from the dry cell battery, but the power required is for the two electromagnetic on-off valves V, V, the temperature detection sensor SI+St, the seating detection sensor 41, and the logic circuit. 45, the temperature detection sensors S+, St and the seating detection sensor 41 consume less power, and each electromagnetic on-off valve V,, V, is driven by a rafting tureenoid, so it only needs to be energized when the valve is opened or closed. Since it is good and consumes little electricity, the life of the dry cell battery is long and it can be used for a long period of time without having to replace the dry cell battery.

Further, in this embodiment, the hot water temperature detection sensor S1 can be turned on only when the seating detection sensor 41 is in the on state, and the hot water temperature can be detected only once. The power required to turn on the sensor S1 can also be effectively saved.

Further, in the present invention, only when the seating detection sensor 41 is in the on state, the hot water temperature detection sensor is turned on, the hot water temperature is detected only once, and then again after a certain period of time has elapsed, the hot water temperature detection sensor S, In this case, the power required to turn on the hot water temperature detection sensor S1 can be saved, and, for example, if the seated state continues for a long time and the hot water temperature in the hot water pipe l drops. In such cases, check the hot water temperature detection sensor S again.

Since it is possible to perform a discarding hot water operation by turning on the cleaning nozzle N, mixed hot water at an appropriate temperature can be discharged from the cleaning nozzle N toward the private parts. Therefore, the user can relieve himself comfortably.
