[0004]

In such a conventional configuration, when the user enters the bathroom 101, it is necessary to turn on the illuminator 103 or to operate the ventilator 100. And ventilation fan switch 10
There are times when you forget to put in 5 or forget to turn it off.

[0005] In particular, since the operation state of the ventilation device 100 is more difficult to confirm than the illuminator 103, the ventilation fan switch 1
Many people forget to insert or erase 05.

An object of the present invention is to solve such a problem, and it is an object of the present invention to automatically start and stop a ventilator to efficiently discharge moisture.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is to connect a fan motor for a ventilation fan and a switch for automatic operation switching in series, and to a power supply via a ventilation fan switch for turning on and off the power supply. A ventilation fan circuit, a connector, and a humidity sensor having a humidity sensor and a power supply circuit having a response switch responsive to the humidity sensor, wherein the connector has first and second ends connected to both ends of the ventilation fan circuit. And a third power connection terminal which connects a connection point of a fan and an automatic operation switching switch in the ventilation fan circuit, and a first and second power connection terminals of the connector are provided with a humidity. The power receiving terminal of the humidity sensor in the sensing unit is freely connectable, and the terminal of a power supply circuit having a response switch in the humidity sensing unit is freely connectable to the third power connection terminal. An operation unit that opens a switch for automatic operation switching of the ventilation circuit when the humidity detection unit is connected to the connector, and closes the switch for automatic operation switching when the humidity sensing unit is removed or disabled. Is provided as a configuration of a ventilation device.

[0008]

In the above configuration, when the humidity sensing unit is not connected to the connector, the switch for automatic operation switching of the ventilation fan circuit is closed, and the fan motor for the ventilation fan is always energized. The drive is controlled by turning on and off of.

Next, when the humidity sensing unit is connected to the connector, power is supplied to the humidity detector, and a power supply circuit having a response switch is connected to the fan motor in the ventilation fan circuit through a third power supply connection terminal. It is connected to the connection point of the switch for automatic operation switching. A switch for automatic operation switching of the ventilating fan circuit is opened by an operating part of the humidity sensing unit, the responsive switch is connected to the fan motor in series, and the fan motor operates according to a detection state of the humidity detector. Automatic stop operation will be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG.
A humidity sensing unit 3 and a fan motor 4 provided inside a ventilation fan 2 provided on a ceiling of a bathroom 1 such as an apartment house;
It consists of an illuminator 5 provided separately and a lighting switch 6 and a ventilating fan switch 7 provided outside the bathroom. FIG. 3 shows the internal structure of the ventilation fan 2, and FIG.
And the arrangement of the ventilation fan switch 7. The ventilation fan 2 and the illuminator 5 are connected to the power supply 8 through the ventilation fan switch 7 and the illumination switch 6, respectively, and are energized.

Next, the power supply circuit will be described in detail with reference to FIG. The fan motor 4 of the ventilation fan 2 is connected in series with a switch 10 for automatic operation switching, and both ends are connected to a _first terminal a ₁ and a second terminal b ₁ of a power input terminal 9 to form a ventilation fan circuit. I have. The first terminal a ₁ and the second terminal b ₁ are the first and second power supply connection terminals a ₂ and b _{2 of the} connector 11.
It is connected to the. The connection between the fan motor 4 and the switch 10 for automatic operation switching is connected to the third power supply connection terminal c ₂ of the connector 11.

The humidity sensing unit 3 provided inside the ventilation fan 2 has a power supply circuit 12 having a humidity sensor 13 and a humidity sensing switch 14, and further has an operating section 15. The power receiving side of the humidity sensor 13 is freely connectable to the first and second power supply connection terminals a ₂ and b ₂ of the connector 11, and one end of the power supply circuit 12 is connected to the third power supply connection of the connector 11. It is freely connected to the terminal c _2. When the humidity sensing unit 3 is connected to the connector 11, the operation unit 15 opens the switch 10 for automatic operation of the fan motor 4.

Hereinafter, the operation of the ventilation device having the above configuration will be described. When using the bathroom, the illuminator 5 can be operated by the illumination switch 6. The ventilation fan 2 can be operated by the ventilation fan switch 7. However, once the switch is turned on, the humidity sensor 13 in the humidity sensing unit 3 provided inside the ventilation fan 2 monitors the state of the humidity in the bathroom and exceeds the set humidity. Automatically operates, the fan motor 4 is operated by the humidity sensing switch 14, and the humidity sensor 13 stops operating as the humidity decreases due to ventilation, and automatically stops by the humidity sensing switch 14. is there.

When the humidity sensing unit 3 is not used or removed, the switch 10 for automatic operation of the fan motor 4 is opened, so that it can be used as a normal ventilation fan 2.

[0016]

As is apparent from the above description of the embodiment, according to the present invention, when the bathroom is used, the operation of the ventilation fan, which is suddenly forgotten, is automatically performed by the humidity sensor provided inside the ventilation fan. In addition, the ventilation fan is operated properly, and the effect of efficiently preventing the occurrence of mold due to insufficient ventilation can be obtained. When the humidity sensor is not used, it can be used as a normal ventilation fan by removing or disabling the humidity sensor, and the effect on the equipment can be obtained at the time of service or the like.
