Lighting device E lights up, and the temperature or humidity in the bathroom rises by opening the bath lid, and the lighting is performed after the predetermined time required for the hot water supply operation to the bathtub, for example, 5 minutes or more in this embodiment. It is determined whether or not the appliance E has been turned off.

When it is determined in step S5 that the user has gone out of the bath, the temperature of the dressing room B is detected in step S6, and the ventilation operation time is set according to the temperature of the dressing room B in step S7. That is, in the winter, when the ventilation operation is performed for a long time, the bathroom temperature decreases and the person bathing next feels cold. People feel hot. Therefore, the time to reach the temperature and humidity at which the next bather can comfortably bathe is set according to the outside temperature. Then, in step S8, the cooler blower 16 is driven, and the cool air louver 30 closes the cool air outlet 5.
The damper 27 is moved to a position where the exhaust passage 29 is opened, and the ventilation operation of the bathroom A is performed. This ventilation operation is continued until the timer ends in step S9, and when the timer expires, the operation ends in step S10.

The air sucked from the intake port 4 by the driving of the air passes through the cooler 13 and is exhausted to the outside through the exhaust passage 29. On the other hand, the air sucked from the intake port 4 by the drive of the second blower 19 is heated by the condenser 18, becomes warm air, and is blown from the warm air outlet 6 to the bathroom A. The warm air from the warm air outlet 6 is blown toward the washing area by the second louver 31 to prevent the user from feeling cold on the floor when the user enters the bathroom A by warming the washing area. It has become.

In step S12, it is determined whether or not the user has taken a bath, in this embodiment, the bathroom lighting switch 40 has been operated, and if so, step S13.
In (1), the blower amount of the cooler blower 14 is increased, the blower amount of the condenser blower 19 is decreased, and the warm air louver 31 is swung. In this state, the amount of air blown by the first blower 14 is increased, so the temperature of the condenser 18 rises, and hot hot air is blown from the hot air outlet 6. Further, since the air blown from the hot air outlet 6 reduces the air blower of the condenser air blower 19 and swings the warm air louver 31, the air blown directly to the user is reduced, which is not suitable for the user. It does not give a pleasant feeling.

In step S14, it is determined whether or not the user has gone out of the bath, and in this embodiment, the bathroom lighting switch 40 has been operated to turn off the lighting fixture E. When the lighting fixture E is turned off, the ventilation operation is started in step S15. Transition.

If the lighting fixture E is not turned off in step S14, it is judged in step S16 whether or not the operation stop is instructed by the operation of the bathroom heating switch 36, and when the bathroom heating switch 36 is operated, step S1
In step 7, the operation is stopped, and in step S18, the user waits until getting out of the bath. When it is detected in step S18 that the user goes out of the bath, ventilation operation is performed in step S19.

In step S20, the dressing room temperature is detected based on the output from the dressing room temperature detection sensor 46, and in step S21, the ventilation operation time is set based on the temperature. That is, when the temperature is high as in summer, the ventilation time is lengthened to lower the temperature in the bathroom A and
When the temperature is low as in the winter season, the ventilation time is shortened to minimize the temperature drop in the bathroom A and reduce the discomfort of the next person bathing. In step S22, it is determined whether or not the timer set in step S21 has expired. When the timer has expired, the operation is stopped in step S23.

Next, the operation when the clothes drying switch 34 of the control unit 33 is operated to select the clothes drying mode will be described with reference to the flowcharts shown in FIGS. 11 and 12.

In step S24, the humidity of the bathroom A and the humidity of the place where the air is supplied into the bathroom A, in this embodiment, through the grill D provided on the door C between the bathroom A and the dressing room B The humidity of the dressing room B that supplies air to the bathroom A is compared. The outputs of the bathroom humidity detection sensor 45 and the dressing room humidity detection sensor 47 are corrected based on the outputs of the bathroom temperature detection sensor 44 and the dressing room temperature detection sensor 46, respectively, to obtain a more accurate bathroom humidity and dressing room humidity. The humidity of the dressing room B is detected and the humidity of the dressing room B is compared with that of the bathroom A.
