<Characteristic configuration>
Next, the bathroom heating dryer A according to this embodiment has a characteristic configuration as described below. Therefore, when bathroom heating is performed while performing mist spraying using the bathroom heating dryer A of this embodiment, the temperature in the bathroom 2 is the temperature of hot water for mist supplied from the hot water supply device (heat source device 16). Controlled.
A description will be given below.

  The hot water supply device (heat source device 16) includes a temperature setting unit (not shown) that sets the temperature of the hot water to be supplied. That is, the hot water supply means in the present invention includes a mist hot water temperature setting unit for setting the temperature of the mist hot water.

  When the temperature detected by the bathroom temperature thermistor TH3 (the temperature of the air sucked from the bathroom) is higher than the temperature detected by the mist temperature thermistor (hot water temperature detector for mist) TH1, the controller B is the hot water for heating in the present invention. The heating on-off valve (thermal valve) 17 which is a flow control unit is controlled to block the flow of the heating hot water flowing through the heating hot water conduit 15.

  When the temperature detected by the bathroom temperature thermistor TH3 (the temperature of the air sucked from the bathroom) is lower than the temperature detected by the mist temperature thermistor (mist water temperature detector) TH1, the controller B performs heating in the present invention. The heating on-off valve (thermal valve) 17 serving as the hot water flow control unit is controlled to maintain the flow of the hot water flowing through the hot water pipe 15 for heating.

  Since the temperature of the hot water flowing through the heating hot water conduit 15 is normally set to about 70 ° C. to 80 ° C., the control unit B controls the thermal valve (heating hot water flow control unit) 17. When the heating hot water flowing through the heating hot water pipe 15 is maintained, the air sucked from the bathroom 2 is heated by the hot air heat exchanger 13 and the temperature of the air sucked from the bathroom 2 is Rises and returns to the bathroom 2.

  Further, when the control unit B controls the heating on-off valve 17 to block the flow of the warm water for heating that flows through the warm water pipe 15, the air sucked from the bathroom 2 is exchanged for warm air. Without being heated by the vessel 13, the temperature of the air sucked from the bathroom 2 does not rise and is returned to the bathroom 2.

  In addition, when the air sucked from the bathroom 2 is not heated by the hot air heat exchanger 13 and is returned to the bathroom 2 as it is (without increasing the temperature), heat is radiated to the outside in the bathroom 2, etc. As a result, the temperature in the bathroom 2 decreases.

Therefore, when performing bathroom heating while performing mist spraying,
(A) When bathroom heating is executed, control is performed when the temperature detected by the bathroom temperature thermistor TH3 (the temperature of the air sucked from the bathroom) is higher than the temperature detected by the mist temperature thermistor (hot water temperature detector for mist) TH1. Part B controls the thermal valve (heating hot water flow control unit) 17 to shut off the flow of heating hot water flowing through the heating hot water conduit 15;
(B) When the temperature detected by the bathroom temperature thermistor TH3 (the temperature of the air sucked from the bathroom) is lower than the temperature detected by the mist temperature thermistor TH1 (hot water temperature detecting unit for mist), the control unit B By controlling the on-off valve 17 and maintaining the heating hot water flowing through the heating hot water conduit 15, the temperature in the bathroom 2 is for the mist supplied from the hot water supply means (heat source machine) 16. It will be controlled by the temperature of hot water.

  Further, when bathroom heating is performed without performing mist spraying, the heating temperature is set by the bathroom temperature setting switch 42.

  When the bathroom temperature setting switch 42 is operated, a set temperature related to bathroom heating when mist spraying is not performed is displayed on the state display unit 40 provided in the bathroom operating device 30.

  The display on the status display unit 40 may be a digital display by numbers such as 37 ° C., 38 ° C., 39 ° C., 40 ° C., and 41 ° C., or D1, D2, D3, D4, D5, It may be a symbolic display.

When displaying the display on the status display unit 40 with symbols such as D1, D2, D3, D4, and D5,
D1: Approximately 37 to 38 ° C
D2: approximately 38 to 39 ° C
D3: Approximately 39 to 40 ° C
D4: 40 to 41 ° C.
D5: Good usability can be ensured by describing that the temperature is controlled to 41 ° C. or higher.

  In this embodiment, the display on the status display unit 40 is configured to be displayed (digitally displayed) by numbers such as 37 ° C., 38 ° C., 39 ° C., 40 ° C., and 41 ° C.

  When bathroom heating is performed without performing mist spraying, the temperature detected by the bathroom temperature thermistor TH3 (temperature of the air sucked from the bathroom) is displayed on the state display unit 40 (the bathroom when mist spraying is not performed). When the temperature is higher than the heating set temperature), the control unit B controls the heating on-off valve (heating hot water flow control unit) 17 to block the flow of the heating hot water flowing through the heating hot water conduit 15. .

  When the temperature detected by the bathroom temperature thermistor TH3 (the temperature of the air sucked from the bathroom) is lower than the temperature displayed on the state display unit 40 (the bathroom heating set temperature when mist spraying is not performed), the control unit B Then, the heating on-off valve (heating hot water flow control unit) 17 is controlled to maintain the heating hot water flowing through the heating hot water conduit 15.

  In this embodiment, when bathroom heating is performed without performing mist spraying, when mist spraying is started by operating the mist sauna switch 134 in the bathroom, the mist temperature thermistor TH1 ( The temperature detected by the mist hot water temperature detector) is displayed.

  As described above, in the bathroom heater / dryer A provided with the bath mist device according to this embodiment, when bathroom heating is performed while performing mist spraying, the temperature in the bathroom 2 is increased by the bathroom heating to the hot water supply device (heat source). Since the temperature of the hot water for mist supplied from the machine 16) is controlled, when mist spraying is started by operating the mist sauna switch 134 in the bathroom when performing bathroom heating without performing mist spraying, By displaying the temperature detected by the mist temperature thermistor TH1 (hot water temperature detection unit for mist) on the state display unit 40, the user can set appropriate settings for bathroom heating according to the use situation of the bath mist device. It becomes possible to obtain information about the temperature, and it is possible to ensure the ease of use.

  Moreover, since the bathroom heating dryer A provided with the bath mist apparatus concerning this embodiment does not require the liquid heat exchanger for mist, it is manufactured compared with the thing provided with the conventional liquid heat exchanger. Cost can be reduced.

  In addition, this invention is not limited to the said embodiment, A various application and deformation | transformation are possible within the scope of the invention.
