Hereinafter, each of the preliminary heating operation, the heating operation during bathing, the ventilation operation, the drying operation, and the cool air operation will be described. The preliminary heating operation controls the opening and closing of the thermal valve 16 so that the exhaust fan 19 is stopped and the circulation fan 14 is operated, and the temperature in the bathroom 1 is maintained at the preset temperature for preliminary heating. Hot water as a heat medium is circulated and supplied to the heat exchanger 15, and the circulating air heated by the heat exchanger 15 is blown out of the outlet 12 into the bathroom 1. Then, the circulation fan 14 is operated in a strong state so that the amount of air blown into the bathroom 1 becomes the amount of air for preheating, and as shown in FIG.
The direction of the movable louver 17 is adjusted by an electric motor so that the direction in which air is blown into the bathroom 1 is directed to the washing place in the bathroom 1.

In the heating operation during bathing, the exhaust fan 19 is stopped and the circulation fan 14 is operated, and the temperature in the bathroom 1 is maintained at the set temperature for preliminary heating, as in the above-described preliminary heating operation. In this way, the opening and closing of the heat valve 16 is controlled to circulate and supply hot water as a heat medium to the heat exchanger 15, and the circulating air heated by the heat exchanger 15 is blown out of the outlet 12 into the bathroom 1. Like that. Then, the circulation fan 14 is operated in a weak state so that the amount of air blown into the bathroom 1 becomes smaller than the amount of air used for preliminary heating, and the amount of air used for heating during bathing is reduced.
As shown in (a), the direction of the movable louver 17 is adjusted by an electric motor so that the direction of blowing air into the bathroom 1 is directed to the washing place in the bathroom 1.

In the ventilation operation, the exhaust fan 19 is operated while the operation of the circulation fan 14 is stopped and the thermal valve 16 is maintained in the closed state, and the movable louver is operated as shown in FIG. The operating state of the movable louver 17 is adjusted by an electric motor so that the closed state of the movable louver 17 is provided, and the air sucked from the bathroom 1 is exhausted.

In the drying operation, the circulation fan 14 is operated, and the opening and closing of the thermal valve 16 is controlled so that the temperature in the bathroom 1 is maintained within the set temperature range for drying. While circulating and supplying hot water as a heat medium, the exhaust fan 19 is operated to discharge a part of the air sucked from the bathroom 1 through the exhaust duct 18 to the outside.
Circulating air heated by the heat exchanger 15
2 is blown into the bathroom 1. Then, the direction of the movable louver 17 is adjusted by the electric motor so that the direction in which the air is blown into the bathroom 1 is substantially directly below the drying direction. That is, the air heated through the circulation ventilation passage 13 is supplied to the bathtub A
The air is blown out in a direction directly below the object to be dried, such as clothing, which is suspended and supported by a locking device or the like at the upper part.

In the cool air operation, the circulation fan 14 is operated while the thermal valve 16 is kept closed, and the exhaust fan 19 is operated so that a part of the air sucked from the bathroom 1 is exhausted by the exhaust duct 18. The air sucked from the interior of the bathroom 1 is blown out into the bathroom 1 through the circulation ventilation passage 13 without being heated while being discharged to the outside.
Then, the direction of the movable louver 17 is adjusted by the electric motor so that the blowing direction of the air into the bathroom 1 is the blowing direction for the cool air (for example, the direction toward the washing place).

[Other Embodiments] (1) In the above embodiment, an example is shown in which the bathroom remote controller 7 can be instructed to start and stop the heating operation and the cool air operation during bathing. Alternatively, it is also possible to configure and execute only the heating operation during bathing so as to be instructable. Further, the bathroom remote controller 7 is configured to be able to instruct information such as a ventilation amount and a set temperature for preliminary heating in the heating operation and the cool air operation during the bathing in addition to the start and stop of the heating operation and the cool air operation during the bathing. It is also possible to carry out. That is, the bathroom remote controller 7 can instruct start or stop of a part or all of the plurality of air conditioning operations, and is not limited to the selection information of the start and stop of the plurality of air conditioning operations. It is possible to configure and execute the condition selection information so as to be instructable.

(2) In the above embodiment, an example is shown in which the control unit 2 includes the air conditioning control unit 3a and the hot water supply control unit 4a in a state where information can be freely communicated. The control unit controls the operation of the bathroom air conditioner 3 and the bath water heater 4 so that the control unit is communicable with the main remote controller 6 and the bathroom remote controller 7. It is also possible to configure and implement communication freely between them.

(3) In the above embodiment, the bathroom air conditioner 3
However, it is configured to be able to perform each of the preliminary heating operation, the heating operation during bathing, the ventilation operation, the drying operation, and the cool air operation. However, the bathroom air conditioner 3 may be any device that performs the heating operation during bathing. Other operations may be configured to be able to execute some operations, or may not execute other operations.

(4) In the above embodiment, the bath water heater 4
However, each of the general hot water supply operation, the automatic hot water supply operation, and the hot water supply operation is configured to be executable. The bath water heater 4 only needs to supply hot water into the bathroom 1, and performs only the automatic hot water supply operation. It may be something.

(5) In the above embodiment, the bathroom air conditioning and hot water supply device according to the present invention comprises the bathroom air conditioning device 3 and the bath water heating device 4
Although an example in which the two devices are combined is shown, the bathroom air-conditioning and hot-water supply device according to the present invention is provided with an air-conditioning unit for performing air-conditioning in the bathroom 1 and a hot-water supply unit for supplying hot water into the bathroom 1. It is also possible to configure from a device. Also,
