Abstract

PROBLEM TO BE SOLVED: To eliminate an unpleasant feeling and dangerousness by setting a temperature lower than a favorite temperature set by a user to a target temperature until a timer part starts to count time, and setting the favorite temperature to the target temperature after a count of time is finished. SOLUTION: At the beginning of boiling-up, since a detecting temperature in a sensor part 4 becomes lower than a preset temperature in a second wash water temperature setting part 9 to set a temperature lower than a temperature set by a first wash water temperature setting part 5 to set a favorite wash water temperature by a user, a heater part 3 is turned on. When the detecting temperature in the sensor part 4 exceeds the preset temperature in the setting part 9, the heater part 3 is turned off, and a timer part 10 starts to count time. Next, while repeating operation by which the heater part 3 is turned on when the detecting temperature in the sensor part 4 becomes lower than a target temperature controlled by a target temperature control part A12 and is turned off when it exceeds the target temperature, it is brought near to the preset temperature in the setting part 5. When the timer part 10 finishes a count of time, the preset temperature in the setting part 5 is set to the target temperature.

2. Description of the Related Art FIG. 5 shows a toilet apparatus (block diagram) according to a conventional technique. In FIG. 5, a washing unit 1 discharges washing water to a local body part. Wash water is stored in the tank 2. The heater unit 3 is built in the tank 2,
The washing water in the tank 2 is heated. The sensor unit 4 is built in the tank 2 and detects the temperature of the washing water in the tank 2. The first cleaning water temperature setting unit 5 is constituted by, for example, a volume, and a user can set a desired cleaning water temperature by turning the volume. FIG. 6 shows an external view of the first cleaning water temperature setting unit 5. In FIG. 6, the setting of the hot water temperature is performed by adjusting the knob 6 to the setting range 7. The heater control unit 8 compares the temperature detected by the sensor unit 4 with the target temperature. If the target temperature is higher, the heater unit 3 is turned on, and if the detected temperature is higher, the heater unit 3 is turned off. To control the temperature of the washing water inside. Here, when the temperature set by the first washing water temperature setting unit 5 is set as the target temperature, the so-called overshoot occurs in which the actual washing water temperature exceeds the set temperature due to the heat capacity of the washing water in the tank 2. In order to prevent this overshoot, a method as described in JP-B-5-13215 has conventionally been adopted. The second cleaning water temperature setting unit 9 sets a temperature lower than the first cleaning water temperature setting unit 5 by a certain fixed temperature. The timer unit 10 initializes the timer if the temperature detected by the sensor unit 4 is lower than the temperature set by the second washing water temperature setting unit 9, and when the detected temperature becomes higher than the temperature set by the second washing water temperature setting unit 9. From a certain time. The target temperature control unit C11 sets the temperature set by the second cleaning water temperature setting unit 9 as the target temperature until the timer unit 10 finishes the time measurement, and sets the first cleaning water temperature setting unit after the timer unit 10 finishes the time measurement. The temperature set in 5 is set as the target temperature. That is, once the temperature of the washing water drops, the heater unit 3 is turned on until the temperature reaches a set temperature lower by a certain temperature than the temperature set by the user, and after that, the heater unit 3 is controlled at that temperature for a certain period of time. By controlling the heater section 3 with the temperature, the cleaning water is boiled in a short time and the overshoot is suppressed.

However, in the above configuration, the set temperature in the second washing water temperature setting section 9 is suddenly changed from the set temperature in the first washing water temperature setting section 5 to the target temperature. Is considerably higher than the temperature detected by the sensor unit 4, which causes overshoot. FIG. 7 shows the detected temperature and the target temperature at the time of boiling in the conventional example, and the ON / OFF state of the heater unit 3. Since the heater unit 3 is kept on until the detected temperature reaches the target temperature after the set temperature is switched, the heater unit 3 is turned off.
Then overshoot has occurred. Further, in order to increase the capacity of the tank 2 or to shorten the boiling time, the heater section 2 has a high wattage, which means that the overshoot increases. In other words, if a high-wattage heater is used to shorten the boiling time, when the washing water is discharged to a local part of the human body, not only it feels hot but also there is a danger of burns.
