Next, the operation of the toilet apparatus having the above configuration will be described with reference to the flowchart of FIG. At each cycle time of the control routine, the room temperature of the toilet room 30 is read from the room temperature sensor 34, and the detection of the human body 33 by the infrared sensor 32 is monitored, so that the user tries to enter the toilet room 30 by the door 30b of the entrance 30a.
Is opened, an infrared sensor 32 provided on a remote controller 31 installed on a wall facing the entrance 30a senses heat rays emitted from the human body 33. When the human body 33 is not detected, the air conditioner 13 is kept off.

When the detection signal of the human body 33 is output from the infrared sensor 32, the toilet lid 6 is opened and the display means 35 is displayed.
Is displayed, and the user sees the displayed room temperature. At this time, it is preferable that the room temperature display is a display with high illuminance such as an LED so that the user pays attention to the displayed room temperature without fail. In particular, the room temperature is lower than the set temperature T ° C. at which the air conditioner 13 is operated as described later. When the air conditioner 13 is not operated, it is preferable that the display be flashed to call attention.

Next, the detected room temperature is a predetermined set temperature T ° C.
It is determined whether it is higher. This set temperature T ° C. is set to a temperature at which cooling is considered necessary even in view of the policy of achieving energy saving by avoiding cooling use as much as possible, and is set, for example, to about 25 ° C. When the room temperature is equal to or lower than the set temperature T ° C., the air conditioner 13 is kept off. On the other hand, when the room temperature is higher than the set temperature T ° C., the air conditioner 13 is operated.

When the air conditioner 13 starts operating, after several tens of seconds, the second heat exchanger 16 is in a state where heat exchange with the conditioned air is possible, and the conditioned air is blown out from the blower port 20. Thus, when the user sits on the warm water flush toilet seat 3 on the toilet 1 or stands in front of the toilet 1 and uses the toilet, air-conditioning air blows out from the air outlet 20 to the user,

It is configured to be switchable between the direction toward the nape and the direction toward the entire toilet room, and a timer is provided in the control unit 24 so that the user faces the nape for a certain time after detecting that a person is sitting on the toilet seat 5. The air-conditioning air can be blown out and then blown out in the direction toward the entire toilet room, or intermittently and alternately, so that the air-conditioned air is blown out for a long time and does not feel uncomfortable it can.

According to the present embodiment, the room temperature is displayed on the display means 35 when the user enters the toilet room 30 as described above, so that the temperature should not be used to operate the air conditioner 13 for energy saving. If it is known, even if it is a little hot, it is possible to endure it without much discomfort, and as a result, it is possible to achieve energy saving. When a human body is detected in the toilet room 30, the display means 35 is displayed.
Is used to display the room temperature, so that even when a display with high illuminance is displayed, power consumption can be reduced.

In the above-described embodiment, an example is shown in which the display means 35 is provided on the remote controller 31. However, the display means 35 can be arranged at any place where the user of the toilet room 30 can easily see.

In the above-described first embodiment, an example is shown in which the infrared sensor 32 for detecting a human body is provided on the remote controller 31 of the hot water flush toilet seat 3. However, as in the second embodiment shown in FIG.
An infrared sensor 32 may be provided on the main body 4 of the warm water flush toilet seat 3. In this case, it can be integrated with the main body 4 of the warm water flush toilet seat 3 and can be configured compactly. Further, if the infrared sensor 32 that outputs a detection signal only when the human body 33 approaches is used, it is possible to control the air conditioner 13 to operate strongly only when the user sits on the toilet seat 5. Further, in combination with the first embodiment, the remote controller 3
When the detection signal is output from the infrared sensor 32 provided in the apparatus 1, the operation state may be changed so that the entire toilet room 30 is air-conditioned. Furthermore, the arrangement position of the infrared sensor 32 can be arbitrarily selected. For example, when the infrared sensor 32 is arranged on the ceiling, there is no detection blind spot, no detection error of the human body 33 occurs, and the air conditioner 13 is reliably detected and operated when necessary. Can be done.
