  In a mist device using a mist nozzle, a large amount of mist-like mist is sprayed, so that the humidity can be increased rapidly. However, when the bather bathes the body with a large amount of mist, the body gets wet, and there is a possibility that the bather cannot visually perceive the sweating effect.

  On the other hand, if a mist device equipped with a mist nozzle that ejects finer mist, an ultrasonic humidifier, or a humidifier using fan crushing is used, the body of the bather is difficult to wet with the mist. The bather will be able to feel the sweating effect.

  However, since the flow rate of the mist nozzle that ejects fine mist is small, temperature control on the side of the water heater that supplies hot water to the mist nozzle cannot be performed, and mist is ejected by water. Even in humidifiers using ultrasonic humidifiers or fan crushing, cold humidified air is blown out into the bathroom.

  As a result, in order to prevent a decrease in the temperature of the bathroom, it is necessary to continue blowing hot air from the heater even while bathing. However, driving the humidifier and the heater at the same time may increase the noise in the bathroom. there were.

If it is determined that the temperature difference is greater than the heating operation switching temperature difference, for example, the temperature difference is greater than + 1 ° C., an instruction to stop the blowing of the steam V is transmitted to the sub-control unit 8A.

  The sub-control unit 8A stops driving the heater 23H when receiving an instruction from the main control unit 7A to stop the discharge of the steam V. Thereby, the blowing of the steam V from the humidifier 2A stops.

  Step SA28: When the main control unit 7A stops the discharge of the steam V from the humidifying device 2A, the temperature detection sensor 38a detects the temperature of the bathroom 101.

  Step SA29: The main control unit 7A determines whether the temperature difference between the temperature of the bathroom 101 detected by the temperature detection sensor 38a and the set temperature is equal to or less than a predetermined heating operation switching temperature difference.

  Step SA30: When the main control unit 7A determines that the temperature difference between the temperature of the bathroom 101 detected by the temperature detection sensor 38a and the set temperature is equal to or less than a predetermined heating operation switching temperature difference, the process of step SA26 described above , And an instruction to reduce the output and blow off the steam V is transmitted to the sub-control unit 8A.

  In addition, during the steam humidification operation, it is possible to reduce the noise by stopping the bathroom air conditioner 3A. Although the humidifying device 2A is also provided with the blower fan unit 21, since the air volume is smaller than that of the bathroom air conditioner 3A, the generation of noise due to driving the fan is suppressed. In addition, since the heater 23H of the humidifying device 2A and the heater 32 of the bathroom air conditioner 3A are not driven at the same time, it is possible to reduce power consumption, and it is possible to reduce restrictions on installable houses by suppressing power consumption. .

  Furthermore, the bather can change the set temperature by controlling the sub-operation unit 6A in the bathroom 101, and can change the interior of the bathroom 101 to a desired temperature during bathing. At this time, when the difference between the set temperature and the actual temperature in the bathroom 101 is smaller than the predetermined heating operation switching temperature, the generation of noise can be prevented by dealing with the change in the steam output in the humidifying device 2A. Moreover, when the temperature difference is large, the temperature in the bathroom 101 can be raised in a short time by restarting the heating operation in the bathroom air conditioner 3A.

When it is determined that the temperature difference is not more than the heating operation switching temperature difference, for example, + 1 ° C. or less, an instruction to reduce the output of the steam V is transmitted to the sub-control unit 8A.

  When the sub control unit 8A receives an instruction from the main control unit 7A to reduce the output of the steam V, the sub control unit 8A changes the output of the heater 23H. For example, control for reducing the output of the heater 23H to 1500 W is performed.

  Step SB25: The main controller 7A determines that the temperature difference between the set temperature and the temperature of the bathroom 101 detected by the temperature detection sensor 38a is higher than the set temperature. If it is determined that the temperature difference is greater than the heating operation switching temperature difference, for example, the temperature difference is greater than + 1 ° C., an instruction to stop the blowing of the steam V is transmitted to the sub-control unit 8A.

  The sub-control unit 8A stops driving the heater 23H when receiving an instruction from the main control unit 7A to stop the discharge of the steam V. Thereby, the blowing of the steam V from the humidifier 2A stops.

  Step SB26: When the main control unit 7A stops the discharge of the steam V from the humidifying device 2A, the temperature detection sensor 38a detects the temperature of the bathroom 101.

  Step SB27: The main controller 7A determines whether the temperature difference between the temperature of the bathroom 101 detected by the temperature detection sensor 38a and the set temperature is equal to or less than a predetermined heating operation switching temperature difference.

  Step SB28: If the main control unit 7A determines that the temperature difference between the temperature of the bathroom 101 detected by the temperature detection sensor 38a and the set temperature is equal to or less than a predetermined heating operation switching temperature difference, the process of step SB24 described above , And an instruction to reduce the output and blow off the steam V is transmitted to the sub-control unit 8A.

  As a result, the sub-control unit 8A drives the heater 23H with a predetermined output and drives the fan motor 25a, whereby the humidifier 2A reduces the output and blows the steam V from the blow grill 27b.

  As described above, in the humidifying and heating operation mode of the second operation example, while the mist M is ejected by the humidifying device 2A, the warm air HA is blown out by the bathroom air conditioner 3A to humidify and heat the bathroom 101. When the room temperature reaches the set temperature, it is switched to the steam humidifying operation in which the steam V is blown out by the humidifying device 2A. When the inside of the bathroom 101 is suitable for bathing, the steam humidifying operation is automatically performed regardless of the bather's operation. Can be switched automatically.

  Moreover, the bather can recognize whether or not the bathroom 101 is in a state suitable for bathing by providing means for notifying that the bathroom 101 is in a state suitable for bathing by humidification heating.

  Step SD2: In the humidifier 2D, it is determined from the output of the water level sensor 22w whether or not the water level in the water tank 22D has decreased to a predetermined lower limit position.

  Step SD3: When the humidifier 2D determines from the output of the water level sensor 22w that the water level in the water tank 22D has decreased to a predetermined lower limit position, the water supply valve 22sb is opened.
