Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a heat generation system of the sanitary washing device. A toilet seat 13 includes a heating wire heater 11 and a thermistor 12 for detecting the temperature of the toilet seat 13 due to heat generated by the heating wire heater 11. On the other hand, a heating wire heater 16 and a thermistor 15 are also provided in the hot water tank 18 to heat the cleaning water 17 and detect the temperature of the cleaning water 17 respectively. Although not shown, the above-mentioned Japanese Patent Laid-Open No.
As in the case of Japanese Patent No. 58343, it has a cleaning function unit including an electric pump for pressurization, a cleaning nozzle, a drying function unit using a motor for a fan, and a charm function unit including a motor for changing the position of the cleaning nozzle.

[0007] The microcomputer 10 has an input interface 10a and an output interface 10b.
2, 15 and the operation switch unit 14 are electrically connected. On the other hand, both heaters 11 and 16 are electrically connected to the output interface 10b.

The operation switch unit 14 is a normally-open type cleaning switch 1 for starting each of the above-mentioned cleaning, drying and charming function units and for stopping each of the function units.
4a, switch for drying 14b, switch for charm 14
c and a stop switch 14d. Therefore, the microcomputer 10 receives the electric signals relating to the temperatures of the toilet seat 13 and the washing water 17 and the closing of the switches 14a, 14b, 14c, and 14d through the input interface 10a to start the functional units of the washing, drying, and charm. And an electrical signal regarding the stop.

An energizing signal is applied to the heaters 11 and 16 from the microcomputer 10 via the output interface 10b, so that the heaters 11 and 16 generate heat. Moreover, the toilet seat 13 of each thermistor 12, 15
Alternatively, if the detected temperature of the cleaning water 17 is
When the temperature exceeds the preset temperature of the toilet seat 13 or the cleaning water 17 within 0, the urging signal is stopped and the heaters 11 and 16 are stopped.
Heat generation is interrupted. After this, toilet seat 13 or washing water 1
When the temperature of 7 decreases, the energizing signal is output again. By repeating this, the temperatures of the toilet seat 13 and the washing water 17 become
It is kept at approximately the set temperature.

As shown in FIG. 2, the microcomputer 10 includes a timer 21, an arithmetic unit 22, a temperature setting unit 23, and a temperature control unit 24. Timer 21
Indicates a day with a so-called clock for 24 hours, and transmits each time zone data to the arithmetic means 22. Arithmetic means 22
Determines the use of the cleaning device based on the input of an electrical signal when each of the switches 14a, 14b, 14c, 14d is closed.
Moreover, the use time is confirmed from the timer 21, and it is counted that the operation has been performed in the time zone to which the use time belongs. This counting is performed, for example, from several days to one month, and the usage frequency for each time zone is calculated.

Incidentally, the timer 21 sets the day to 24 hours as described above.
It has a time function that indicates the time and a calendar function that updates the day of the week every 24 hours.

The temperature setting means 23 sets the normal set temperatures for the toilet seat 13 and the washing water 17 at 35 ° C. and 45 ° C. and lowers the temperature, that is, sets the second set temperatures for energy saving to 28 ° C. and 36 ° C. And Note that a heating device (not shown) stops the heating. Further, when the temperature setting means 23 is provided with the use frequency for each day of the week of the cleaning device for one month, for example, from the arithmetic means 22, the temperature setting means 23 detects the unused time based on the use frequency. The second set temperature is set in a time zone where the cleaning device is not used, while a normal set temperature is set in a time zone where the cleaning device is used.

The control means 24 includes a normal setting temperature and a second setting temperature of the toilet seat 13 and the washing water 17 corresponding to the current time from the temperature setting means 23, and a toilet seat 13 and the washing water 17 from the thermistors 12 and 15. And the detected temperature of
Each detected temperature is compared with the set temperature. If the detected temperature is lower than the set temperature, an energizing signal for the heaters 11 and 16 is output, and if the detected temperature exceeds the normal set temperature and the second set temperature, an additional signal is output. The output of the power signal is stopped. As a result, toilet seat 1
The temperature of the cleaning water 3 and the cleaning water 17 are substantially maintained at the temperatures set by the temperature setting means 23, respectively. Moreover, the temperature setting means 2
The set temperature set to 3 is a normal set temperature in a time zone when the cleaning device is used, and is set to the second set temperature in a time zone when the cleaning device is not used. The toilet seat 13 and the washing water 17 are heated at a temperature that matches the actual use condition for each time zone.

[0014]

Table 1 is a table in which the temperature setting means 23 in a certain home sets the temperature on the day based on the usage time period of the cleaning device on each day from the day to 4 days before.

As shown in Table 2, the temperature setting means 23 determines the time period during which the cleaning device has been used in the past four days up to that day and the time period before and after that time by using the normal set temperature of the day (the day of the bottom row in the table). , And the other time zone is the second set temperature (0 in the setting column of the day at the bottom of the table).
Set as a time zone. If the cleaning device is used during the second set temperature time zone on the day, the temperature setting means 23 stores the usage time on the day and the control means 24 sets the time zone to the normal set temperature time. The temperature of the heaters 11 and 16 and the heating device of the toilet room (not shown) are controlled as a band.

When the calculating means 22 detects the use of the washing device, in addition to the operation of the operation switch section 14, the toilet seat 13 and the washing water 17 are provided with a seating sensor or a human body detecting sensor for detecting entry of the user, A heating device (not shown) can be automatically detected by a door sensor, and a heating device (not shown) can be automatically detected by a human body detection sensor.

The temperature setting means 23 may set the time interval of the use time zone of the cleaning device to every 30 minutes. Also,
The usage time may be stored, for example, several days to one month. In the case of about one month, the setting as described above is performed until the usage time data is collected. After the usage time data is collected, only the usage time data of the same day is used, and the usage time is used. It is possible to increase the probability of the band and save heat energy.

[0017]

As described above, according to the present invention, the amount of heat generated by the heat generating means can be controlled according to the time period when the sanitary washing device is used, and the heat generating means can generate heat while conforming to the actual use. Therefore, there is an effect that the heat generated by the washing water and the toilet seat can be saved.
