The heater 33b is either energized on or energized off. During the cooling unit 18 operation, the second water heater 33b is turned off regardless of the incoming water temperature or the set hot water temperature. Therefore, as shown in FIG. 5, in winter when the incoming water temperature is low, the second hot water heater 33b is turned off, and even if the first hot water heater 33a is fully energized, the electric capacity is insufficient. Although the hot water temperature is not reached, the total power consumption of the toilet apparatus 11 is 710 W, which is a total of the compressor 26 (AC 100 V-160 W) and the first hot water heater 33 a (AC 100 V-550 W). On the other hand, as shown in FIG. 6, in the summertime when the incoming water temperature is high, the second hot water heater 33b is originally in an off state and thus has no effect on the hot water temperature, and the total power consumption of the toilet apparatus 11 is the compressor. 26 (AC100V-160W) and the first water heater 33a (AC100V-550W), which is a total of 710W. Therefore, the cooling means 18 is normally operated in the summer when the incoming water temperature is high and the second hot water heater 33b is off, so that the hot water temperature of the local hot water washing means 19 can be kept at a predetermined temperature. There is no problem, and the total power consumption of the toilet apparatus 11 when the local hot water washing means 19 is operated during the operation of the cooling means 18 is calculated using the first water heater 33a and the second water heater 33b in winter. The power consumption during simultaneous energization can be suppressed to 1100 W or less, and the space and cost of the AC power circuit of the control means 23 can be suppressed.

  In the first embodiment, when the operation start of the cooling means 18 and the operation start of the electric opening / closing means 20 overlap, the operation of the cooling means 18 is started first, and after the start-up state of the compressor 26 is finished, the electric opening / closing operation is performed. The operation of the means 20 is started. As a result, it is possible to prevent the electric switching means 20 from becoming unstable due to output fluctuation of the DC power supply circuit due to sudden increase in power consumption of the AC power supply which requires a large amount of power when the compressor 26 is started. It should be noted that a large amount of electric power is required for starting up the compressor 26 for a short time, and even if the electric opening / closing means 20 is actually operated thereafter, there is no need to feel uncomfortable.

Further, in the first embodiment, when the temperature is higher than the high reference temperature (for example, 25 ° C.), only the cooling means 18 can be operated, and when the temperature is lower than the high reference temperature and the temperature is lower than the low reference temperature (for example, 15 ° C.) Only the toilet seat heating means 25 and the room heating means 21 can be operated when the temperature is equal to or lower than the low reference temperature, so that the cooling means 18, the toilet seat heating means 25, and the room heating means according to the toilet room temperature. By properly using 21, the overall power consumption of the toilet device can be suppressed, and the space and cost of the AC power circuit of the control means 23 can be suppressed.

  As described above, in the first embodiment, the overall power consumption of the toilet device can be suppressed during operation of the cooling means, and the space and cost of the AC power circuit of the control means can be suppressed. The temperature can be maintained at a predetermined temperature.
