Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing device suitable for being applied to a so-called western style toilet bowl.

[0002]

2. Description of the Related Art Conventionally, there has been known a sanitary washing device for washing sanitarily and comfortably by spraying washing water toward a user's local area. This sanitary washing device is attached to a Western-style toilet bowl 30 as shown in FIG. In this toilet bowl 30, the rear end of the toilet seat 32 is rotatably attached to a dome-shaped main body 31. A water reservoir 33 is provided on the bottom of the main body 31, and a plurality of projections 35 that abut on the peripheral edge 34 of the main body 31 are provided on the lower surface of the toilet seat 32, whereby the toilet seat 32 is stably mounted on the main body 31. Placed.

FIG. 9 shows the structure of a conventional sanitary washing device 10 of the type that is additionally attached to the existing toilet bowl 30 later. In this sanitary washing device 10, the entire device is the toilet bowl 3 described above.
A horizontal shaft 37 is attached to a rear portion of a frame body 36 to be attached to 0, and a toilet lid 38 and a rear end portion of a toilet seat 39 having a central portion opened are rotatably attached to the horizontal shaft 37. Further, a washing nozzle 43A and a bidet nozzle 43B are attached to the lower side of the toilet seat 39.

Further, a control unit 40 for controlling the amount and pressure of water to be washed is attached to the side of the frame 36, and an operation unit 41 is provided on the surface thereof. The operation section 41 is provided with an oscill cleaning selection switch 41A and a bidet selection switch 41B for selecting the oscilloscope cleaning nozzle 43A and the bidet nozzle 43B, a stop button 41C, and a water pressure adjusting knob 41D.

Washing water is supplied into the control unit 40 by a water distribution pipe 42 connected to an external pump (not shown) or the like, and from there, a washing nozzle 43A or a bidet nozzle arranged behind the toilet seat 39. Water is sent to 43B and jetted out. Each of the nozzles 43A and 43B is adapted to expand and contract due to the pressure of cleaning water. That is, when not in use, that is, when the cleaning water is not supplied, each nozzle 4
3A and 43B are completely housed inside the nozzle cover 45 by the urging force of a spring (not shown). When cleaning water having a pressure higher than the tension of the spring is supplied, the nozzles 43A, 43B
Is extruded and placed at a predetermined position.

On the lower surface of the toilet seat 39, when the sanitary washing device 10 is attached to the toilet bowl 30 as shown in FIG.
A plurality of protrusions 44 are provided on the main body 31 of the toilet bowl 30 for stable holding. When the sanitary washing device 10 is attached to the existing toilet bowl 30, the toilet seat 32 of the toilet bowl 30 is used.
After removing, the frame 36 is attached to the main body 31 of the toilet bowl 30. At this time, the water distribution pipe 42 is, for example, the toilet 30
It is connected to a water distribution pipe (not shown) or the like of the wash water storage tank 2 arranged at the rear of the. When the toilet bowl 30 is used, the toilet seat 39 of the sanitary washing device 10 is tilted down on the main body 31 and seated thereon.

When using this sanitary washing device 10,
The water pressure adjusting knob 41D (FIG. 9) that adjusts the jetting pressure of the washing water is set to a desired setting value, and the operating portion 41 selects the washing nozzle 43A or the bidet nozzle 43B to jet the washing water. The spouted water cleans the area hygienically and comfortably.

Further, in this sanitary washing device 10, FIG.
As shown in FIG. 5, when the cleaning operation is started, the maximum pressure F is maintained until the fixed time T elapses regardless of the set pressure Fn (for example, F2 or F3) set by the water pressure adjustment knob 41D of the cleaning water.
After the water is sent at 1, the water is controlled to be sent at the set pressure F2 or F3. However, the set pressure Fn is the maximum value F
When it is 1, the water supply pressure of the cleaning water is constant until the cleaning operation is completed. The maximum pressure supply time T is set in advance so as to coincide with the time E when the nozzles 43A and 43B complete the protrusion when the cleaning water is sent at the maximum pressure F1. By controlling the pressure of such wash water,
No matter which pressure the water pressure adjusting knob 41D is set to, the nozzles 43A and 43B are quickly projected and arranged at predetermined positions. Therefore, it is possible to reduce the time difference between the operation of the operation unit 41 and the actual ejection of the washing water, so that the user does not feel discomfort.

[0009]

By the way, in the conventional sanitary washing device 10, a pump (not shown) for ejecting washing water is often driven by a motor. Therefore, when shifting from the maximum pressure F1 to the set pressure F2 or F3, the water supply pressure falls due to the inertia of the motor in a gentle descending line as shown in FIG. For this reason,
For example, in the case of the set pressure F2 or F3, it takes more time until the set pressure F2 or F3 actually drops even if the maximum pressure supply time T elapses. This time becomes longer as the set pressure becomes lower. Therefore, in some cases, the high-pressure cleaning water may locally hit for a certain period of time immediately after the completion of the ejection cleaning nozzle 43A or the bidet nozzle 43B, and the cleaning may not be started at the set pressure desired by the user. There was a problem of giving a pleasant feeling.

Therefore, the present invention has been made to solve the above-mentioned problems and is capable of quickly arranging the nozzle at a predetermined position and starting the ejection of washing water at a pressure desired by the user. A cleaning device is proposed.

[0011]

In order to solve the above problems, in the present invention, a cleaning nozzle for ejecting cleaning water, a pressure control means for controlling the water supply pressure of the cleaning water, and a water supply pressure are set. A sanitary washing device having a pressure setting means for performing and a nozzle moving means for moving the washing nozzle from a storage position to a use position by the water supply pressure of the washing water, wherein the set pressure of the pressure setting means from the start of the water supply of the washing water. The cleaning water is sent at a predetermined pressure for a corresponding time, and then the cleaning water is sent at the set pressure of the pressure setting means.

[0012]

As shown in FIG. 4, when the rotary knob 15A (FIG. 3) is operated to select the "washing" mode or the "bidet" mode, the pressure set by the water pressure adjusting knob 15B (FIG. 3) of the washing water is set. Maximum pressure F according to Fn (n = 2 to 5)
The microcomputer 56 (FIG. 2) determines the time at which the cleaning water is jetted at 1, that is, the maximum pressure supply time Tn (n = 2 to 5). Then, the cleaning water is supplied at the maximum pressure F1 only during the determined maximum pressure supply time Tn, and then is controlled to be supplied at the set pressure Fn. When the set pressure Fn is set to the maximum pressure F1, the jetting pressure of the washing water does not change and remains the maximum pressure F1 until the end of the washing operation.

The maximum pressure supply time Tn is the maximum pressure F
It is set in consideration of the time required for the pressure drop from 1 to the set pressure Fn. That is, each nozzle 11A, 11B
The set pressure Fn is reached by the time point E when the protrusion is completed (FIG. 2). Regarding the relationship between the set pressure Fn and the maximum pressure supply time Tn, an optimum state is measured in advance, and this state is input to the microcomputer 56.

As described above, by changing the maximum pressure supply time Tn according to the set pressure Fn, each nozzle 11A, 11B (FIG. 2) can be quickly placed at a predetermined position regardless of the set value of the set pressure Fn. At the same time, the jet of cleaning water is started at the set pressure Fn desired by the user.

[0015]

Next, one embodiment of the sanitary washing device according to the present invention will be described in detail with reference to the drawings. In addition,
The same parts as those described above are designated by the same reference numerals and detailed description thereof is omitted.

FIG. 1 shows a state in which the sanitary washing device 1 according to the present invention is attached to an existing Western style toilet 30 and the toilet seat 32 is raised. In this sanitary washing device 1, the washing nozzle 11A and the bidet nozzle 11B, which are arranged so that the positions where the washing water is ejected are different, are attached to the nozzle attachment portion 12 placed on the back side of the main body 31. ing.
FIG. 1 shows a state in which the nozzles 11A and 11B are stored,
That is, the non-use state is shown.

The nozzle mounting portion 12 is the peripheral portion 3 of the toilet 30.
It is securely attached to the rear end portion of No. 4 by a suction plate (not shown). The upper plate portion 12A of the nozzle mounting portion 12 is provided with coupling portions 12C on both end sides. In addition, each nozzle 11
A connecting portion 13B is attached to the side surface of the control portion 13 disposed beside the main body 31 so as to adjust the height so as to supply the cleaning water to A and 11B. The nozzle attachment portion 12 is attached to the control portion 13 by connecting the coupling portion 12C to the control portion 13.

Hot water is supplied from the water storage tank 13A in the controller 13 to the oscillating cleaning nozzle 11A and the bidet nozzle 11B through pipes 14A and 14B. The pipes 14A and 14B include a connecting portion 13B and a nozzle mounting portion 12.
It is arranged along the lower side of. These pipes 14
Since the diameters of A and 14B are smaller than the gap between the toilet seat 32 and the main body 31, there is no risk of being crushed.

Further, the washing nozzle 11A and the bidet nozzle 11B are adapted to expand and contract by the pressure of the washing water. That is, when not in use, that is, when the cleaning water is not supplied, it is completely stored inside the nozzle cover 12B by the urging force of springs (not shown) attached to the nozzles 11A and 11B. When cleaning water having a pressure higher than the tension of the spring is supplied, the washing nozzle 11A and the bidet nozzle 1
1B is pushed out and placed at a predetermined position. The bidet nozzle 11B protrudes longer than the wipe cleaning nozzle 11A.

FIG. 2 is a block diagram showing the structure of the sanitary washing device 1. The suction pipe 53 connected to the external water storage tank 2 is connected to the tank 1 via the pump 52A.
Supply wash water to 3A. A motor 52B for driving the pump 52A is connected to the pump 52A. Further, a heater 54 for warming the wash water is attached to the tank 13A. The motor 52B and the heater 54 are controlled by the microcomputer 56, and the water pressure adjusting knob 15B for adjusting the pressure and flow rate of the washing water and the water temperature adjusting knob 15C for adjusting the temperature of the washing water are connected to the microcomputer 56. The microcomputer 56 controls the rotation speed of the motor 52B according to the jet pressure of the washing water set by the water pressure adjusting knob 15B, and controls the heater 54 according to the temperature of the washing water set by the water temperature adjusting knob 15C.

The pipe 42 connected to the tank 13A is connected to a switching cock 55, and the switching cock 55 switches the washing water discharged from the tank 13A to switch the pipe 14
Supply to A or pipe 14B. Pipes 14A and 14B
Are the washing nozzle 11A and the bidet nozzle 1 respectively.
1B, whereby the washing water is jetted from the washing nozzle 11A or the bidet nozzle 11B.

Further, as shown in FIG. 3, an operation section 15 is provided on the upper side of the control section 13, and a plurality of modes,
In this example, a relatively large rotary knob (rotary knob) 15A, a water pressure adjusting knob 15B, and a water temperature adjusting knob 15C are arranged to select the "stop" mode, the "oscillating cleaning" mode, and the "bidet" mode. . Water pressure adjustment knob 15B
The water temperature adjusting knob 15C has a stronger water force or a higher water temperature as it is rotated clockwise.

The rotary knob 15A is formed in a dome shape, and the indicator wire 15 provided on the surface of the rotary knob 15A is rotated.
When D is directed to the position of the "stop" mode provided on the panel surface of the operation unit 15, the rotation of the rotary knob 15A is once stopped and the water supply of the washing water is stopped as described later. Indicator line 15D
Toward the position of the "Oshiri wash" mode or the "Bidet" mode, the rotation stops here and the nozzle 11 for the Oshiri wash
Cleaning water is jetted from the nozzle A for A or the bidet 11B. In this example, the positions of the "oscillation cleaning" mode and the "bidet" mode are provided 180 degrees apart from each other, and the position of the "stop" mode is provided in the middle.

Now, in the sanitary washing device 1, when the rotary knob 15A is operated to select the "oscillation washing" mode or the "bidet" mode, the setting of the flush water flow adjusting knob 15B is performed as shown in FIG. Pressure Fn (n = 2
5), the microcomputer 56 (FIG. 3) determines the time for ejecting the wash water at the maximum pressure F1, that is, the maximum pressure supply time Tn (n = 2-5). Then, the wash water is fed at the maximum pressure F1 only during the determined maximum pressure supply time Tn, and then is controlled to be fed at the set pressure Fn. In addition, when the set pressure Fn is set to the maximum value F1, the jetting pressure of the cleaning water does not change and reaches the maximum value F1 until the cleaning operation ends. Further, N in the figure indicates the minimum pressure required for the nozzle protrusion.

The maximum pressure supply time Tn is the maximum pressure F
It is set in consideration of the time required for the pressure drop from 1 to the set pressure Fn. That is, the washing nozzle 11
The set pressure Fn is reached by A or by the point E when the projection of the bidet nozzle 11B is completed. In this sanitary washing device 1, as shown in FIG. 5, the maximum pressure supply time Tn is set to increase in proportion to the increase in the set pressure Fn. This is because the higher the set pressure Fn is, the smaller the pressure difference between the maximum pressure F1 and the set pressure Fn is. Therefore, the time required for the pressure drop to the set pressure Fn is shortened. This is because the set pressure Fn will soon be reached. This set pressure F
The optimum state of the relationship between n and the maximum pressure supply time Tn is measured in advance, and this state is input to the microcomputer 56 (FIG. 2).

As described above, by changing the maximum pressure supply time Tn according to the set pressure Fn, each nozzle 11A, 11B (FIG. 2) can be quickly placed at a predetermined position regardless of the set value of the set pressure Fn. At the same time, the jet of cleaning water is started at the set pressure Fn desired by the user. Therefore, the user does not feel discomfort or discomfort. In this example, when the set pressure Fn is low, the cleaning water is sent at the maximum pressure F1 in a shorter time, so that each nozzle 11A,
The protrusion of 11B is slightly delayed, but this is a very short time, so there is no problem in actual use.

FIG. 6 is a flow chart of the cleaning process 60 when the cleaning operation is performed in the sanitary cleaning device 1. When the "cleaning" mode or the "bidet" mode is selected, the set pressure Fn by the water pressure adjusting knob 15B is confirmed (step 61). Then, the maximum pressure supply time Tn is determined based on the confirmed set pressure Fn (step 62), and the wash water is delivered at the maximum pressure F1 (step 63).

Further, it is determined whether or not the maximum pressure supply time Tn determined in step 62 has elapsed (step 64). When the maximum pressure supply time Tn has elapsed, the supply pressure of cleaning water is reduced from the maximum pressure F1 to the set pressure Fn (step 65). Then, it is judged whether or not the "stop" mode is selected (step 66), and when the "stop" mode is selected, the water supply of the washing water is stopped.
When the "stop" mode is not selected, it is determined whether or not a fixed time, for example, 1 minute, has elapsed from the start of the cleaning operation (step 67). If it is within 1 minute, the water supply of the wash water is continued, and when 1 minute has elapsed, the water supply of the wash water is stopped. With this, even if a child or the like makes a mistake, for example, it is possible to prevent the wash water from being left out.

When the sanitary washing device 1 is used, the toilet seat 32 is placed on the main body 31 as shown in FIG. As a result, the portion of the sanitary washing device 1 disposed inside the main body 31 of the toilet 30 becomes almost invisible from the outside, and only the control unit 13 is disposed outside.

[0030]

As described above, according to the present invention, the cleaning nozzle for ejecting cleaning water, the pressure control means for controlling the water supply pressure of the cleaning water, the pressure setting means for setting the water supply pressure, and the cleaning water are provided. A sanitary washing device having a nozzle moving means for moving the washing nozzle from the storage position to the use position by the water feeding pressure of the washing water at a predetermined pressure for a time corresponding to the set pressure of the pressure setting means from the start of feeding the washing water. The wash water is sent, and then the wash water is sent at the set pressure of the pressure setting means.

Therefore, according to the present invention, it is possible to quickly arrange the nozzle at a predetermined position and start jetting the washing water at the pressure desired by the user, and the user feels strange. There is an effect that it will not be done.
