FIG. 1 is a control block diagram of a heating toilet seat or a sanitary washing device according to an embodiment, and FIG. 2 is an explanatory diagram of an operation example of a heating toilet seat to which this control is applied.

As shown in FIG. 1, the controller 6 includes a temperature setting operation unit (for example, a temperature control switch) 7 for setting a target temperature of hot water for the heating toilet seat or the sanitary washing device, and a power saving mode setting operation unit (for example, power saving). Signals are input from a mode setting switch, a switch for designating a power saving operation time zone, etc.) 8, a room temperature sensor 9 for detecting the air temperature in the toilet room, and a temperature sensor 10 provided on a heated toilet seat or a hot water tank. This controller 6
Controls the heater 11 of the heating toilet seat or the hot water tank based on these input signals to control the temperature of the hot water in the heating toilet seat or the hot water tank to the target temperature.

[0010] In the case of a heated toilet seat, when the power saving mode is not executed, the target temperature of the toilet seat is selected from a range of, for example, 28 to 40 ° C by a temperature setting operation unit. When the power saving mode is being executed, the target temperature of the toilet seat is switched between two levels according to the room temperature in the toilet room. In this embodiment, when the room temperature is 10 ° C. or higher, the target temperature of the heating toilet seat is 26 ° C., and when the room temperature is lower than 10 ° C., the target temperature is 28 ° C.

In FIG. 2, a timer is set so that the power saving mode is executed between midnight and 6:00 am. The operation mode is the normal operation mode until midnight, and the target temperature of the heating toilet seat is 40 ° C. When the power saving mode starts at midnight, since the room temperature at this time is 10 ° C. or higher, the power saving operation with the target temperature set to 26 ° C. starts. Room temperature then gradually decreases. When the room temperature falls below 10 ° C. around 2:30 am, the target temperature during the power saving operation is switched to a higher temperature of 28 ° C.

This toilet room is used for about 10 minutes from about 4:00 am, and at this time, the room temperature is reduced to 10 by operating an air conditioner or a hot air fan in the toilet room.
The temperature rose to above ℃. Therefore, while the room temperature is 10 ° C. or higher, the target temperature is switched to 26 ° C. again.
After that, the air conditioner or hot air fan stops and the room temperature returns to 1
At around 4.30 am when the temperature has dropped below 0 ° C., the target temperature is again switched to the higher temperature of 28 ° C. At 6:00 am, since the power saving mode is canceled and the operation returns to the normal operation, the target temperature is set to 40 ° C. again.

When the room temperature is low (in this embodiment, when the temperature is lower than 10 ° C.), the target temperature of the heating toilet seat is raised, so that the user can sit on the heating toilet seat during the power saving operation or immediately after canceling the power saving operation. The sensation of cold when it is relaxed is considerably reduced.

The operation example shown in FIG. 2 relates to a heated toilet seat, but the same applies to a sanitary washing device. The target temperature of the hot water is selected from a range of, for example, 36 to 40 ° C. by the temperature setting operation unit. When the operation example of FIG. 2 is applied to a sanitary washing device, during power saving operation, the target temperature of the hot water in the hot water tank is lower when the room temperature is 10 ° C. or higher (for example, 34 ° C.).
° C), and when the room temperature is lower than 10 ° C, the temperature is set higher (for example, 36 ° C). During normal operation, the target temperature of the hot water in the tank is the temperature set by the temperature setting operation unit.

In the above embodiment, the power saving mode is executed during the time period set by the timer. However, regardless of the timer, the power saving mode is always executed, and the heating toilet seat or the heating toilet seat which cancels the power saving mode only when a human body is detected. The present invention can be applied to a sanitary washing device.

In the above embodiment, the room temperature is detected by the room temperature sensor 9;
As described in No. 8, an index value corresponding to room temperature, such as a heating toilet seat or hot water temperature rising speed when the heater is turned on or a heating toilet seat or hot water temperature decreasing speed after the heater is turned off, is observed, and based on this data, The target temperature may be switched during execution of the power saving mode.

In the above-described embodiment, the target temperature in the power saving mode is set to the higher and lower two-step control. However, the target temperature may be set to three or more steps, and the target temperature may be continuously raised and lowered continuously. .
