Therefore, in the bathroom heating dryer 1 of the present embodiment, three The rotating plates 181, 181... Do not protrude outward from one side surface 106 of the main body case 10.

  FIG. 5 schematically shows the operating principle during a drying (hot air drying) operation in the bathroom heating dryer 1 of the present embodiment.

  In order to perform the drying operation, a “drying” switch of an operation input unit (not shown) installed outside the bathroom 7 is pressed. The control unit (not shown) of the bathroom heater / dryer 1 and the ventilation unit 2 receives a signal from the operation input unit, sets each rotary plate 181 of the opening / closing device 18 to a fully open posture, and the circulation fan 11 and the ventilation fan 21. Is activated. The control unit opens the on-off valve 14 and starts supplying hot water to the heat exchanger 12 when a predetermined time (about 1 to 2 minutes) has elapsed from the start of operation of the circulation fan 11 and the ventilation fan 21.

  Thereby, in the bathroom heating dryer 1 and the ventilation unit 2 which are connected in communication, an air flow is generated as indicated by a white arrow in the figure. That is, the air in the bathroom 7 is drawn into the circulation air passage 102 from the suction port 103 by the driving of the circulation fan 11, and is heated by the heat exchanger 12 in the circulation air passage 102, and then the air outlet 104 and the louver. 17 is returned to the bathroom 7.

  A part of the air drawn into the internal space 100 from the suction port 103 is introduced into the ventilation unit 2 through the opening / closing device 18 in a fully opened state, and is discharged to the outdoors through the exhaust path 22. At this time, the ventilation unit 2 also ventilates the dressing room 8 and the toilet room 9.

  The control unit closes the on-off valve 14 and stops the supply of hot water when the temperature sensor 16 detects that the air sucked into the bathroom heater / dryer 1 has reached the first temperature (for example, 50 ° C.) or higher. Thereafter, when the temperature sensor 16 detects that the air sucked into the bathroom heater / dryer 1 has become a second temperature (for example, 45 ° C.) or less, the on-off valve 14 is opened to resume the supply of hot water.

  In FIG. 6, the operation principle at the time of heating operation in the bathroom heating dryer 1 of this embodiment is schematically shown.

  In order to perform the heating operation, the “heating” switch of the operation input unit outside the bathroom 7 is pressed. The control unit of the bathroom heater / dryer 1 and the ventilation unit 2 receives a signal from the operation input unit, sets each rotary plate 181 of the opening / closing device 18 to a fully closed posture, and sets a predetermined time (about 1 to 2 minutes). When the time has elapsed, the on-off valve 14 is opened and supply of hot water to the heat exchanger 12 is started. The control unit operates the circulation fan 11 when the temperature sensor 15 detects that the temperature of the hot water to be supplied exceeds a predetermined temperature (for example, 60 ° C.).

  Thereby, in the bathroom heating dryer 1, the air flow as shown by a white arrow in the figure is generated. That is, the air in the bathroom 7 is drawn into the circulation air passage 102 from the suction port 103 by the driving of the circulation fan 11, and is heated by the heat exchanger 12 in the circulation air passage 102, and then the air outlet 104 and the louver. 17 is returned to the bathroom 7.

  When the temperature sensor 16 detects that the air sucked into the bathroom heater / dryer 1 has reached a third temperature (for example, 44 ° C.) or more, the control unit closes the on-off valve 14 and stops the supply of hot water. Thereafter, when the temperature sensor 16 detects that the air sucked into the bathroom heater / dryer 1 has become a fourth temperature (for example, 42 ° C.) or less, the on-off valve 14 is opened to resume the supply of hot water.

  When the “heating” switch of the operation input unit is pressed again, or when a predetermined time has elapsed, the control unit stops the circulation fan 11 and closes the on-off valve 14 to stop the heating operation.

  By the way, when the ventilation operation is performed for 24 hours or when the dressing room 8 or the toilet room 9 is ventilated, the ventilation fan 21 in the ventilation unit 2 is operated weakly. At this time, the ventilation unit 2 ventilates the undressing room 8 and the toilet room 9 as indicated by the dashed arrows in the figure, but the open / close device 18 in the fully closed state is connected to the bathroom heating dryer 1 and the ventilation unit 2.

The controller of the bathroom heater / dryer 1 and the ventilation unit 2 receives the signal from the operation input unit, sets each rotary plate 181 of the opening / closing device 18 to a fully open posture, and activates the ventilation fan 21. The control unit stops the circulation fan 11 and maintains the open / close valve 14 in a closed state.

  Thereby, in the bathroom heating dryer 1 and the ventilation unit 2 which are connected in communication, an air flow is generated as indicated by a white arrow in the figure. That is, the air in the bathroom 7 is introduced into the ventilation unit 2 through the bathroom heater / dryer 1 and the open / close device 18 in a fully opened state, and is discharged to the outside through the exhaust passage 22. At this time, the ventilation unit 2 also ventilates the dressing room 8 and the toilet room 9.

  When the “ventilation” switch of the operation input unit is pressed again, or when a predetermined time has elapsed, the control unit sets each rotary plate 181 of the opening / closing device 18 to the fully closed posture and stops the ventilation fan 21. Stop ventilation operation.
