The bathroom drying apparatus constructed as described above has a drying mode for drying the bathroom BR under the control of a controller (not shown) based on a command from a remote controller (not shown), and circulates air in the bathroom BR. Cool breeze mode, bathroom B
In addition to the heating mode for heating R, the bathroom BR and the dressing room D
R and the toilet TR at a normal ventilation rate, a normal ventilation mode in which the ventilation of the bathroom BR is stopped, ventilation of the dressing room DR and the toilet TR at the normal ventilation rate, and a normal ventilation mode of a bathroom off state, and a bathroom BR. , Dressing room DR and toilet TR
24 hour ventilation mode, in which the ventilation of the bathroom BR is stopped, and the dressing room DR and the toilet TR are ventilated with the small ventilation in the low ventilation mode. It is configured to be able to execute modes and the like.

When the execution of the 24-hour ventilation mode is instructed, the ventilation fan 24 is operated at a rotation speed at which the ventilation amount becomes small while the electromagnet 34 is in a non-energized state. Accordingly, as shown in FIG. 6, the shutter plate 30 is turned to the horizontal position by the suction action of the ventilation fan 24, and the bathroom suction port 23 is opened, so that the bathroom BR and the undressing room DR are opened.
And the toilet TR is ventilated with a small ventilation volume.

When execution of the 24-hour ventilation mode in the bathroom off state is instructed, the electromagnet 34 is turned on and the electromagnet 3 is turned on.
4, the ventilation fan 24 is operated with the small airflow while the shutter plate 30 is held by suction in the vertical position. Therefore, as shown in FIG. 5, since the bathroom intake port 23 is closed by the shutter plate 30, the ventilation of the bathroom BR is stopped, and the dressing room DR and the toilet TR are ventilated with a small amount of ventilation. Therefore, it is possible to prevent a feeling of cool wind accompanying ventilation during bathing.

When the normal ventilation mode is commanded, the electromagnet 3
In a state in which the ventilation fan 24 is in a non-energized state, the ventilation fan 24 is operated at a rotation speed at which the ventilation amount becomes the normal ventilation amount larger than the small ventilation amount. Accordingly, the shutter plate 30 is turned to the horizontal position by the intake operation of the ventilation fan 24, and the bathroom intake port 23 is opened, so that the bathroom BR, the dressing room DR, and the toilet TR have the normal ventilation that is larger than the small ventilation amount. Ventilated by volume.

When the execution of the normal ventilation mode in the bathroom off state is instructed, the electromagnet 34 is turned on, the shutter plate 30 is suction-held by the electromagnet 34 in the vertical position, and the ventilation fan 24 is operated in the normal ventilation mode. Operate by volume. Therefore, since the bathroom intake port 23 is closed by the shutter plate 30, the undressing room DR and the toilet TR are ventilated with the ventilation of the bathroom BR stopped. Therefore, bathroom B
Since R is not ventilated, the ventilation volume of the undressing room DR and the toilet TR can be made larger than the normal ventilation volume.

When the drying mode is instructed, the ventilation fan 24 is operated at a rotation speed at which the ventilation amount is equal to the normal ventilation amount in a state where the electromagnet 34 is de-energized, and the thermal valve 10 is operated. The valve is opened and the circulation fan 7 is operated. Further, based on the temperature detected by a temperature sensor (not shown) for detecting the temperature in the bathroom, when the detected temperature becomes equal to or higher than a heating stop set temperature (for example, 50 ° C.), the thermal valve 10 is closed. Then, the supply of the hot water to the heat exchanger 8 is stopped, and when the detected temperature falls below the set temperature for heating (for example, 40 ° C.), the heat valve 10 is opened to circulate the hot water to the heat exchanger 8. Supply.

Therefore, the shutter plate 30 is turned to the horizontal position by the suction action of the ventilation fan 24 and the bathroom suction port 23 is opened, so that it is sucked from the bathroom BR through the suction part 3 and flows through the circulation air passage 6. A part of the generated air is exhausted through the bathroom intake port 23, and the remainder is heated by passing through the heat exchanger 8 and then returned from the blow-out section 4 to the bathroom BR. Therefore, since the relative humidity of the bathroom BR decreases, the bathroom BR, the laundry installed in the bathroom BR, and the like are dried.
At the same time, the dressing room DR and the toilet TR are also ventilated.

When the cool air mode is instructed, the ventilation fan 24 is operated at a rotation speed at which the air flow becomes the normal air flow, and the circulation fan 7 is operated in a state where the electromagnet 34 is de-energized. . Accordingly, the shutter plate 34 is turned to the horizontal position by the suction action of the ventilation fan 24, and the bathroom suction port 23 is opened.
A part of the air sucked in from R and flowing through the circulation air passage 6 is discharged through the bathroom intake port 23, and the rest is returned from the blow-out section 4 to the bathroom BR. At the same time, the dressing room DR and the toilet TR are also ventilated.

When the heating mode is commanded, the electromagnet 34 is energized, and the shutter plate 30 is attracted and held by the electromagnet 34 in a vertical position. And the thermal valve 10 is opened, and the circulation fan 7 is operated. Further, similarly to the drying mode, when the detected temperature becomes equal to or higher than the heating stop set temperature based on the detected temperature of the temperature sensor, the thermal valve 10 is closed, and the detected temperature becomes equal to or lower than the heating set temperature. Then, the thermal valve 10 is opened.
Therefore, in a state where the bathroom intake port 23 is closed by the shutter plate 30, the air sucked from the bathroom BR through the suction section 3 passes through the heat exchanger 8 and is heated, and then the air is blown out of the bathroom section 4 from the blowout section 4. Returned to BR. In addition, the dressing room DR and the toilet TR are ventilated with a small ventilation volume. That is, the heating mode and the 24-hour ventilation mode with the bathroom turned off are executed in parallel. In this case, since the bathroom inlet 23 is closed, the ventilation performance of the dressing room DR and the toilet TR is prevented from lowering the heating performance of the bathroom BR.
