Then, the operation of the bathroom ventilation fan 50 and the ventilation system using the device as described above are as follows.

In the first embodiment,

To supply outdoor air to the bedroom, living room / kitchen,

First, when the ventilation air supply unit 10 is operated,

The outdoor air is sucked by the intake fan installed inside the ventilation air supply unit 10, and guided to the air supply pipe 20 to supply air to each place, and heat exchange with the heat generated from the heating pipe 70. This occurs, and because the optimized air is supplied to the bedroom or living room, by the heat exchange action, it is possible to reduce the loss of energy as much as possible, maximize the efficiency of the energy, and at the same time can maintain various indoor places in a comfortable state Provide an advantage.

Meanwhile, in the second embodiment,

In order to exhaust the odor and polluted air generated when cooking food in the living room / kitchen,

When the valve 60 installed in the outlet 51a and the inlet 51b is opened, and the drive motor 53a of the blower is operated through the controller,

The driving motor 53a of the blower fan 52 acts, and the impeller 52b of the blower fan 52 rotates, so that the exhaust pipe provided in communication with the bathroom ventilation fan 50 in the living room / kitchen upper part ( 30) At the same time, the indoor odor and contaminated air move to the inside, and are guided to the inlet 51b of the bathroom ventilation fan 50, and then move to the outlet 51a, and discharged to the outside through the exhaust duct 40. Thus, the air in the room can be made comfortable.

Meanwhile, as a third embodiment,

In ventilating the bathroom and living room air at the same time,

First, when the valve 60 installed in the discharge port 51a and the suction port 51b is opened, and the motor 53a of the door part 53 is operated using the controller,

The shaft of the motor 53a rotates, the rod member 53b coupled to the shaft moves vertically upward along the guide portion 51d of the main body 51, and the opening of the lower case 57h is opened. In the state, when driving the drive motor 53a of the blowing fan 52 through the controller,

The impeller 52b of the blower fan 52 rotates so that the air in the living room is moved into the exhaust pipe 30, and then guided to the inlet 51b of the bathroom ventilation fan 50, and then the outlet 51a. At the same time as the discharge through the exhaust duct 40 to the outside, the interior air of the bathroom is guided to the through-hole of the lower case (57h), and then discharged to the outside through the exhaust duct 40 through the outlet (51a) As a result, the air in the bathroom and the living room are simultaneously discharged.

Meanwhile, in the fourth embodiment,

To exhaust only the air inside the bathroom,

When the valve 60 of the inlet port 51b is closed and the valve 60 of the outlet port 51a is opened, the drive motor 53a of the blower fan 52 is operated through the controller.

As the impeller of the blower fan 52 rotates, the air in the living room moves into the connecting pipe, and then the air inside the bathroom is guided to the through-hole of the lower case, and then the exhaust duct 40 passes through the outlet 51a. By being discharged through the outside, only the air inside the bathroom is discharged.

What has been described above is only one embodiment according to the present invention, and the present invention is not limited to the above-described embodiment, and as claimed in the following claims, without departing from the gist of the present invention in the field to which the present invention pertains.
