SUMMARY OF THE INVENTION The present invention provides a ventilation device in at least one of a plurality of rooms, a heating device in a room not provided with the ventilation device, and a ventilation device and a heating device. It is characterized by comprising communication means for communicating, and an exhaust duct for exhausting the atmosphere of a plurality of rooms from the ventilation means to the outside.

Therefore, according to this structure, the intake grill or the dedicated ventilation fan for ventilation and the heating device for heating are integrated into one member.
The ceiling of a dressing room or toilet may have only one ceiling opening, and only one exhaust duct to the outside. As a result, the material cost and the construction cost can be reduced, and the appearance can be improved.

Further, the ventilation means, the heating means or the communication means are provided with opening / closing means for shutting off or communicating the atmosphere of the room provided with the ventilation means and the atmosphere of the room provided with the heating means. Thereby, it is possible to prevent the high humidity atmosphere from flowing backward from the bathroom to the dressing room during the heating operation.

Further, since the opening / closing means is a check valve, the members can be configured at low cost. Further, since the opening / closing means is an opening / closing damper, the ventilation from the dressing room to the bathroom is prevented when the heating operation and the ventilation operation are used together. Thereby, it is possible to efficiently heat the dressing room while maintaining the ventilation of the bathroom.
In addition, since a relay is used to drive the opening / closing means, it can be configured small and inexpensive. Further, since a stepping motor is used for driving the opening / closing means, the opening / closing position can be finely adjusted. In addition, since the control means for controlling the air conditioning system is provided, the ventilation operation and the heating operation can be linked.

Further, when the control means operates the opening / closing means, the ventilation means and the heating means are temporarily stopped, so that the driving device of the opening / closing means can operate without a flow of wind. As a result, it is possible to provide a low torque driving device and a miniaturized power supply. Further, since the heating means is provided with the temperature detecting means for detecting the indoor temperature, the air conditioning system can be operated according to the indoor temperature. Also,
Since the control means opens and closes the opening and closing means based on the temperature obtained by the temperature detection means, it is possible to suppress an increase in indoor temperature. As a result, even if there is a spray can having a risk of explosion, it can be used safely, there is no fear of peeling of the wallpaper, and there is no problem in use even when used in an extremely narrow space. In addition, since the time for fully opening and fully closing the switching means is switched, a simple driving device such as a relay can be used at a low cost. Further, since the opening degree of the opening / closing means is adjusted, delicate temperature adjustment can be easily performed.

Further, the control means changes the ventilation air volume of the ventilation means according to the temperature obtained by the temperature detection means, so that the temperature of the dressing room can be kept constant. In addition, since we decided to switch the time of operation and stop of the ventilation means,
Even in a ventilation drive device in which a delicate air volume cannot be varied like an AC motor, delicate temperature adjustment can be easily performed.

The control means closes the opening / closing means when detecting an abnormality in a device in which the heating means such as a heater inside the heating means is kept energized. Since high-temperature heat is not supplied to the fan or the like, the deformation of the resin member and the use of an expensive material having high heat resistance are not required, and the apparatus can be configured at low cost. Further, since the ventilation duct is provided with the ventilation operation detection means for detecting the operation of the ventilation means, the ventilation operation and the heating operation can be linked. In addition, the ventilation operation detection means,
Since the pressure or the pressure fluctuation in the exhaust duct is detected, the ventilation operation and the heating operation can be interlocked without the electric interlock with the ventilation device. When the ventilation means operates, the fan of the heating means is rotated. Thereby, ventilation is performed in a state where the opening / closing damper of the heating device is opened (the position of the opening / closing damper is above the heater), so that ventilation can be reliably performed from the intake port.
