When the toilet lighting is OFF (lights off) in the illuminance determination step S5, the energized state of the toilet seat heater 41 and the hot water heater 42 is set to a power saving temperature control mode lower than the low temperature period temperature control mode (winter temperature control mode). . In this power saving temperature control mode, as shown in the process F shown in the lower left frame of FIG. 5, the temperature of the toilet seat 4 indicated by the fifth set temperature is 39 ° C. and the temperature of the hot water is 40 ° C.
The toilet seat heater 41 and the hot water heater 4 are operated by the operation of the control unit 32 so that the temperature of the toilet seat 4 is 37 ° C. and the temperature of the hot water is 38 ° C.
The energization of No. 2 is controlled to enter a power saving state.

In this way, the operations in which the temperature determination and the illuminance determination in steps S1 to S5 and the processes A to F are performed are periodically performed by the operation of the control unit 32 as shown in FIG. Therefore, the control unit 32 operates according to a predetermined program. The above temperature may be set to other numerical values.

As described above, in the method in which whether the toilet lamp is turned on or not is detected by the brightness detection sensor 53 when the toilet is used, the toilet lamp 60 leaves the toilet without being turned off. If is kept on, even if the ambient temperature detection sensor 50 detects a temperature higher or lower than the predetermined temperature at which the power saving mode should be entered as in S6 to S8, the power saving control mode is not switched. In order to prevent this, as a first method, the seat switch 33 is activated (detected) when the seat 4 is separated from the seated toilet seat 4, so that a timer included in the control unit 32 is started and a predetermined time ( For example, when the toilet is not used again within any set time of 10 minutes to 30 minutes, the control unit 32 automatically switches to the power saving control mode after the predetermined time has elapsed. Then, when the seating switch 33 is activated (detected) so as to detect that the user has been seated again by using the toilet, the same operation as described above is performed so as to switch to the normal energization control mode.

Further, as a second method, a human sensor 55 that detects the entry / exit of a person into / from the toilet room by infrared rays is connected to the control unit 32, and power saving control is performed from the normal energization control mode based on the detection of the human sensor 55. In addition to switching to the mode and switching from the power saving control mode to the normal energization control mode, the toilet lighting is turned on / off. In this way, a manual switch for turning on / off the toilet light is not necessary, and the operation of the control unit 32 is forcibly performed based on the detection of the human sensor 55 based on the person leaving the toilet room. Switch to power saving control mode. Then, when the human sensor 55 detects the entry of a person again by using the toilet, similarly to the above, it operates so as to switch to the normal energization control mode.

In the state where the control operation as described above is performed, when sitting on the toilet seat 4 in a drunken state, there is a possibility that the sitting time on the toilet seat may become longer, in which case the normal energization control mode is long. There is a risk that the seated person may get a low temperature burn. In order to prevent this, if the normal energization control mode is a predetermined time or longer (for example, any time between 30 minutes and 60 minutes), the timer of the control unit 32 reduces the heat generation of the toilet seat heater 41. Or turn off the power. In this method, the timer is activated from when the seating switch 33 detects the seating, and when the predetermined time (30 to 60 minutes) has elapsed, the heat generation of the toilet seat heater 41 is automatically reduced or turned off. Switch to power saving control mode. This has the effect of preventing low temperature burns when the sitting time is long. If the toilet is not used, the seat switch 33 is activated (detected) when the toilet seat 4 is separated from the seated seat 4, so that the toilet seat heater 41 and the hot water heater 42 are placed in the power saving control mode.
