FIG. 4 shows a timing chart when the operation control circuit operates the cleaning device A-1 or the drying device A-2 to perform cleaning and drying by opening and closing each switch.

The actual operation is explained below. (1) Both the cleaning device A-1 and the drying device A-2 are stopped.

In the state shown in FIG. 3, the stop switch p-s,
The push buttons of the cleaning switch P-W and drying switch P-A are not pressed, and at this time, the stop switch P-8 is on, but both the cleaning switch p-w and the drying switch P-A are off. relay R8 and relay R2 are also turned off.

At this time, contact R□-1 of relay R1 is off, contact R1-
2 is on, contact R0-3 is off, contact R2-1 of relay R2 is connected to contact R1-1 side, contact R2-2 is connected to hot water circuit C-W side, and contact R2-3 is Hot water circuit C
-W hot water heater H-W and triac T are connected.

In this state, the hot water heater H- of the hot water circuit C-W
W is energized and controlled on and off by a thermistor for hot water temperature detection (not shown) and triac T, and the temperature of hot water is automatically controlled, but since contacts R1-3 are off, solenoid valve V and cleaning display are turned on. The lamp LED-W is de-energized, the solenoid valve ■ is closed, and the cleaning indicator lamp L E
D-W is off.

Of course, the hot water circuit C-W has contact R2-2 and contact R2-3.
The current is cut off and the hot air heaters) I-A, H-A'
, the fan motor M1 dryness indicator lamp LED-A has stopped operating.

(2) To start the operation of the cleaning device A-1, press the cleaning switch P-W from the state of (1) to turn it on, and then the relay R1
is turned on, and its contact R1-1 is turned on, so even if you release the cleaning switch P-W and turn it off, the relay R1 is not activated via the stop switch p-s, the contact R2-1, and the contact R1-1. Maintains the on state (self-holding).

On the other hand, when the relay R1 is on, its contact R1-3 is also turned on, energizing the solenoid valve V and opening it. Cleaning water is jetted out from the discharge part 3 to clean the private parts, and the cleaning indicator lamp L E D-W lights up to indicate that cleaning is in progress.

Of course, even during cleaning, the energization of the hot water heater H-W-\ is controlled by the hot water temperature detection thermistor and the triac T, and the temperature of the hot water for cleaning is automatically controlled.

To stop the operation of the cleaning device A-1, press the stop switch P-
Press 8 to turn it off.

Then, relay R1, which was self-held by contact R1-1,
When the stop switch P-8 is turned off, the power supply is cut off and turned off.

Therefore, contact R1-1 is turned off, and stop switch P-8
Even if the stop switch P-8 is turned on by releasing the
1 does not turn on unless the cleaning switch P-W is pressed and turned on.

When relay R1 is turned off, its contact R1-3 is turned off, and solenoid valve ■ and cleaning indicator lamp L E D- are turned off.
The power to W is cut off, the hot water stops jetting to the body's private parts, and the cleaning indicator lamps L E D - W are turned off.

Therefore, the state returns to (1).

(3) To start the operation of the drying device A-2, press the drying switch P-A from the state of (1) to turn it on, then relay R2
is turned on, its contact R2-1 is connected to contact R1-2, and even if the drying switch P-A is released and turned off,
Relay R2 maintains the on state (self-holding) via stop switch p-s, contact R2-1, and contact R1-2.

On the other hand, when relay R2 is turned on, its contact R2-2 is switched from the hot water circuit C-W side to the hot air circuit C-A side, cutting off the power to the hot water circuit C-W side and the hot air heater H.
-A', drying indicator lamp LED-A and fan motor M
・＼It is placed.

Contact R2-3 is also switched to connect hot air heater H-A and triac T, and hot air heater H-A is energized by time proportional control using a thermistor for detecting hot air temperature (not shown) and triac T. The temperature of the hot air is automatically controlled.

Therefore, the drying indicator lamp LED-A lights up, and the air heated by the hot air heaters H-A and H-A' is conveyed by the fan motor M, and hot air is blown from the hot air blowing unit 4 to the private parts of the body. Drying takes place.

The energization of the hot air heater H-A is controlled by a thermistor for detecting the temperature of hot air (not shown) and the triac T, and the energization of the hot air heater H-A' is not controlled.
Flicker occurs when controlling power supply to large capacity heaters at once.
This is because this phenomenon occurs, and also because automatic temperature control of hot air can be performed by dividing the heater and controlling the energization of only one heater H-A.

Therefore, the temperature of the hot air for drying the local area is automatically controlled in the same way as the hot water for washing.

To stop the operation of drying device A-2, press the stop switch P.
Press -8 to turn it off.

Then, relay R2, which was self-holding, switches to stop switch P.
-8 is turned off, the current is cut off and turned off.

Therefore, even if the contact R2-1 switches to the contact R1-1 side and the stop switch P-8 is released and the same stop switch P-8 is turned on, the relay remains as long as the drying switch P-A is not pressed and turned on. R2 does not turn on.

When relay R2 is turned off, its contacts R2-2 and R2-3 are switched, and the dryness indicator lamp LED is switched on.
-A goes out, the power to the fan motor M and hot air heaters H-A and H-A' is cut off, and drying stops.
Returns to state (1).

(4) Press the drying switch P-A during washing.

When relay R1 is in the self-holding state, the private parts of the body are being cleaned as described in (2). In this state, when the drying switch P-A is pressed to turn on, relay R2 is activated.
turns on, its contact R2-1 switches from the contact R1-1 side to the contact R1-2 side, and the self-holding relay R0 turns off, while the other relay R2 switches from the contact R2-1 side to the contact R1-2 side. -2 to maintain the on state.

Therefore, contact R2-2 and contact R2-3 are switched (3)
As mentioned above, local parts of the body are dried.

(5) Press the cleaning switch P-W during drying.

When relay R2 is in the self-holding state, the body parts are being dried as described in i3), but if the cleaning switch P-W is pressed and turned on in this state, relay R2 is in the self-holding state.
0 is turned on, its contact R1-2 is turned off, and relay R2, which was self-holding, is turned off. On the other hand, relay R1 is self-holding through contact R1-1, and is in the on state. maintain.

Therefore, the contacts R2-2 and R2-3 are switched, and the contact R1-3 is turned on, so that the private parts of the body are cleaned as described in (2).

(6) Press the cleaning switch P-W and the drying switch P-A at the same time.

If you accidentally press the cleaning switch P-W and drying switch P-A at the same time and both are on, contact R0-1 is on, but since contact R2-1 is connected to contact R1-2, relay R1 is turned on. is not self-held, and although contact R2-1 is connected to contact R1-2, contact R1-2 is off, and relay R2 is not self-held.

Therefore, while pressing the cleaning switch P-W and the drying switch P-A at the same time, the respective switches P-W and P-A
Therefore, relay R1 and relay R2 are in the on state.

However, since relay R2 is on, contacts R2-2 and R2-3 are connected to the hot air circuit C-A side, (
As mentioned in 3), the body parts are dried and the body parts are not washed.

In this state, even if the cleaning switch P-W is pressed, drying continues.

In addition, if you release the drying switch P-A while pressing the washing switch P-W and the drying switch P-A at the same time, the relay R2 will turn off, and the contacts R2-2 and R2-3 will be connected to the hot water circuit C-W side. Then, the cleaning of the body parts is performed.

(7) While pressing the stop switch P-8, press the cleaning switch P-W or the drying switch P-A.

While the stop switch P-8 is pressed, the stop switch P-
8 is off, and even if washing switch P-W or drying switch P-A is pressed during this time, relay R1 and relay R
No. 2 is not energized, so that the body parts are not washed or dried.

In the above operation, (6) cleansing switch P-
When both W and drying switch P-A are pressed at the same time,
Since the drying operation has priority over the cleaning operation, there is no possibility of accidentally spouting out the cleaning water.

For example, when moving to the drying process after the cleaning process, even if you accidentally press both the drying switch P-A and the cleaning switch P-W, the drying process will take precedence, so the cleaning process will not be performed, and the cleaning process will not be performed. Water is not sprayed out and does not wet clothes or the floor.

On the other hand, when attempting to wash, when both the washing and drying switches P-W and P-A are pressed, hot air is ejected instead of washing water, but this is inconvenient when using the product. It's not something that happens.

In the embodiment described above, push button switches and display lamps are arranged in correspondence with each other on the operation switch board T, but these may be provided on the diagonal front side of the casing A.

Also, depending on the usage condition, for example, a foot switch may be used as an operation switch to operate it with the foot, and a display lamp may be provided in an easily visible position separately from the switch, or it may be blinking or change color to make it easier to distinguish. Alternatively, a sounding body such as a buzzer may be used instead of the lamp.

Furthermore, in the electric circuit of the operation control unit shown in Fig. 3, one stop operation switch P-8 is used to stop both the cleaning device A-1 and the drying device A-2, but two stop switches are provided. The cleaning device A-1 and the drying device A-2 may be stopped individually.

Of course, the electric circuit of the operation control section a is also optional, and although detailed explanation will be omitted, it may be an electric circuit as shown in FIG.

As described above, the present invention provides the following special effects compared to the conventional ones.

a) Since the washing device and drying device are operated by electrical control, even people with weak operating skills such as physically disabled people, the elderly, and children can operate the device reliably and easily, and can treat private parts of the body hygienically. .

b) It is equipped with a washing operation section, a drying operation section, and a stop operation section, and the operation of each device is stopped by the stop operation section, so the operation is easy to understand and there is no risk of erroneous operation.

C) Once the washing operation section or drying operation section is operated,
The washing device or the drying device continues to operate until the stop operation section is operated, and there is no need to keep operating the device during washing or drying, which is not tiring and is easy to use.

d) When both the washing switch and the drying switch are pressed at the same time, the drying action takes priority over the washing action, so washing water will not be sprayed out accidentally and will not wet clothes or the floor.
