御部48からのゲートトリガにより開閉する。Reference numeral 39 in FIG. 4 is a microcomputer, the contents of which will be described below. 41 is a cleaning switch for instructing anus cleaning, 42 is a discharge port cleaning switch for instructing a cleaning operation around the discharge port 21 of the cleaning and discharging device 20, 43 is an on / off detection of the cleaning switch 41 and the setting means 40 A cleaning switch detection unit that sends a signal, 44 is a discharge port cleaning switch detection unit that detects ON / OFF of the discharge port cleaning switch 42 and sends the signal to the setting unit 40, and the setting unit 40 is a cleaning switch detection unit
When the ON signal is input from 43, the set temperature is set to a temperature within a predetermined range (for example, 38 ° C). When an ON signal is input from the discharge port cleaning switch detection unit 44, the setting is changed to a predetermined temperature or higher (for example, 50 ° C.). 45 is an A / D converter that converts the analog signal from the temperature detection unit 45 having the sensor 12 that monitors the temperature of the wash water into a digital signal, and 47 is the set temperature from the setting means 40 and the temperature from the A / D converter 46. A PID control unit that inputs a detection signal and outputs a control signal that reduces the deviation between the two by PID control, 48 is a phase control unit that generates a gate trigger at each phase according to this control signal, 49
Is a triac provided in series with the heater 8 and is opened and closed by a gate trigger from the phase controller 48.

する。When the anus is washed after the urination, the pump 9 is driven and the washing switch 41 is turned on. Then, first, in step 50, the hot water temperature is input from the temperature detection unit 45. In step 51, it is determined whether the cleaning switch is on or off. Since the cleaning switch is on in this case, the routine proceeds to step 52, where the set temperature is set to 38 ° C. After that, in step 53, the heat generation amount of the heater 8 is controlled.

In this case, the process proceeds from the cleaning switch determination in step 51 to the discharge port cleaning switch on / off determination in step 54. Since it is on here, the process proceeds to step 55 to set the set temperature to 50 ° C. After that, in step 53, the heat generation amount of the heater 8 is controlled. If both the cleaning switch 41 and the discharge port cleaning switch 42 are off, the process proceeds to step 56 and the water heater 7
The power supply to the heater 8 is stopped.
次に洗浄水の流れを説明する。 Next, the flow of washing water will be described.

水が放出され、洗浄が行なわれる。The water in the raw tank 2 is sent to the water heater 7 to be heated and enters the discharge means. When the washing switch 41 is turned on and the temperature of the heated hot water is equal to or lower than a predetermined temperature (for example, 38 ° C.), the temperature responsive means 22 which is a shape memory alloy does not generate a displacement force and the valve body
32 holds the discharge valve seat 30 in a closed state by the force of the compression spring 33. Therefore, the hot water that has flowed in from the hot water inlet 28 enters the cylinder inlet 25 through the delivery valve seat 31. Then, the cylindrical piston 27 is pushed out from the cylindrical cylinder 26 against the spring 34. As a result, as shown in FIG. 2, the cylindrical piston 27
Reaches the optimum position of the part to be cleaned of the human body, hot water is discharged from the discharge port 21, and cleaning is performed.

る。Next, when the discharge port cleaning switch 42 is turned on and the temperature of the hot water heated by the water heater 7 reaches 50 ° C. and rises above a predetermined temperature, the temperature response means 22 returns to its shape and a displacement force is generated. The valve element 32 moves in the direction of opening the discharge valve seat 30 and closing the delivery valve seat 31 against the force of the compression spring 33. Therefore,
The hot water flowing from the hot water inlet 28 is discharged from the discharge port 24 through the discharge valve seat 30. Then, the flow to the cylinder inlet 25 is stopped, and the cylindrical piston 27 is pushed back into the cylindrical cylinder 26 by the force of the spring 34. As a result, as shown in FIG. 3, hot water is not discharged from the hot water discharging device, and it is possible to prevent the discharge flow of a predetermined temperature or higher (high temperature water exceeding 42 ° C. in this embodiment) from hitting the human body. .
At this time, the hot water discharged from the discharge port 24 is the cylindrical piston.
Ejects toward 27 and discharges when the cylindrical piston 26 is stored
Eject toward 21. Therefore, the cylindrical piston 27, which is easily soiled by defecation or the like, can be sterilized and washed with high temperature water.
