(FIGS. 1 and 2). However, in FIG. 3, illustration of hot water supply piping is omitted.
However, it is also possible to supply the mist hot water from a hot water supply means provided separately from the heat source unit 16.

  Further, the instruction manual for the bathroom heating dryer A according to this embodiment states that the temperature of the bathroom 2 is maintained at the set temperature in the hot water temperature setting unit for mist provided in the hot water supply means (heat source machine) 16 (that is, The desired temperature (heating setting temperature) in the case of bathroom heating is set by setting the hot water set temperature of the heat source unit 16 that also serves as a hot water supply means).

  Therefore, the user recognizes that the temperature set in the heat source unit 16 becomes the heating set temperature, and then sets the hot water supply temperature in the heat source unit 16, and the hot water is supplied at that temperature, and the bathroom Therefore, it is possible to suppress or prevent the user from being surprised or uncomfortable.

  Thus, when performing bathroom heating, since the hot water setting temperature of the hot water supply means (heat source unit 16) is set so as to be the desired heating temperature (heating setting temperature) for bathroom heating, The operating device 30 is not provided with a switch for setting the temperature in the bathroom during bathroom heating (see FIG. 6).

  In addition, when bathroom heating is performed, the point that the temperature in the bathroom 2 is controlled to the temperature of hot water for mist supplied from the hot water supply means (heat source device 16) by the bathroom heating will be described later.

  A mist temperature thermistor TH <b> 1 that detects the temperature of hot water flowing through the mist hot water supply pipe 20 is disposed upstream of the mist open / close valves 21 a and 21 b in the mist hot water supply pipe 20.

  Moreover, FIG. 4 is a figure which shows an example of the control part B of the bathroom heating dryer A. As shown in FIG. The control unit B includes a memory 28, an arithmetic circuit 29, and the like, and the control unit B is controlled as described below by operating the operation unit 5 and the bathroom operation unit 30 by remote control. It is configured.

<Characteristic configuration>
Next, the characteristic structure of the bathroom heating dryer A provided with the bath mist device according to this embodiment will be described.

  First, in the bathroom dryer with a mist function (bathroom heating dryer) A according to this embodiment, when bathroom heating is performed, the temperature in the bathroom 2 is increased by the bathroom heating from the heat source device 16 that also serves as the hot water supply means in the present invention. The point controlled by the temperature of the supplied mist hot water will be described.

  In the bath mist device of this embodiment, as described above, the hot air heat exchanger 13, the circulation fan 14a, and the like constitute a bathroom heating unit, and the hot water for heating supplied from the heat source unit 16 is used. The air sucked from the bathroom 2 is heated by the hot air heat exchanger 13 by the flow and is blown into the bathroom 2 so that the bathroom 2 is heated.

  In the bathroom heater / dryer A of this embodiment, the hot water supply means (heat source machine) 16 includes a mist hot water temperature setting unit that sets the temperature of hot water to be supplied, that is, the temperature of hot water for mist.

  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 thermal valve 17 which is a flow control unit is controlled to block the flow of the hot water for heating flowing through the hot water pipe 15 for heating.

  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 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 controller B controls the thermal valve 17 to pass through the heating hot water conduit 15. When the heating hot water flowing 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 rises and returns to the bathroom 2. It is.

  In addition, when the control unit B controls the thermal valve 17 to shut off the flow of the hot water for heating that flows through the hot water pipe 15 for heating, the air sucked from the bathroom 2 is converted into a hot air heat exchanger. It is not heated by 13 and 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,
(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 17 to block the flow of the hot water for heating flowing through the hot water pipe 15 for heating,
(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 (mist water temperature detector), the controller B By controlling the valve 17 and maintaining the heating hot water flowing through the heating hot water pipe 15, the temperature in the bathroom 2 can be changed to the hot water for mist supplied from the hot water supply means (heat source machine) 16. The temperature will be controlled.

  The bathroom heating / drying machine A according to this embodiment configured as described above does not require a liquid-liquid heat exchanger, and thus can reduce the manufacturing cost, and does not require complicated control. You can easily control the bath temperature.

  That is, the temperature of the mist hot water supplied from the hot water supply means (heat source machine) 16 is set to a temperature set by the mist hot water temperature setting unit, and the temperature of the air sucked from the bathroom becomes the temperature of the mist hot water. Thus, the flow of hot water for heating is controlled as described above, so that the temperature of the bathroom can be easily controlled so as to become the set temperature by the hot water temperature setting unit for mist that the hot water supply means (heat source device) 16 originally has. It is possible to provide a bath mist device (provided with a bathroom heating dryer) having a simple configuration without requiring a bathroom temperature setting unit for setting the bathroom temperature separately.

  In addition, as described above, in the instruction manual, “the temperature of the bathroom is maintained at the set temperature in the hot water temperature setting unit for mist provided in the hot water supply means”, that is, “when bathroom heating is performed, bathroom heating is performed. The desired heating temperature (heating set temperature) can be designated as the hot water set temperature of the hot water supply means (heat source machine) 16 ”, so that the user can use the heat source machine 16 also serving as the hot water supply means. Recognizing that the set temperature becomes the heating set temperature, the hot water supply temperature in the heat source unit 16 is set, so that the configuration is simple and the bathroom heating / drying device with a bath mist device (ease of use) is provided. Machine).

  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.
