The blower 20 is installed in the housing 10, and the blower 20 is a spindle 24 for transmitting the impeller 21, the motor 23, and the power of the motor 23 to the impeller 21. It consists of. The impeller 21 is installed to face the exhaust port 11 so as to suck air in the room. In addition, the air supply pipe 22 is formed on the central axis of the impeller 21 so as to be connected to the air supply port 12, and ventilation and air supply to one blower through a selection operation of the air supply damper 13 and the ventilation damper 15. Are all possible. In addition, a motor 23 for rotating the impeller 21 is installed inside the housing 10.

Next, one end is inserted into the air supply pipe 22 so that fresh air from the outside of the building is introduced into the air supply pipe 22, and the outside air inlet pipe 30 is installed to be exposed to the outdoors. (30) allows the outside air to flow into the air supply pipe 22 by lowering the pressure inside the air supply pipe 22 by the air speeded up by the rotation of the impeller 21 at the time of supply of the air circulation device (in Bernoulli theorem) As the speed of air increases, the pressure decreases.

In addition, the air supply pipe 22 has a spiral projection (22a) is formed on the inner wall to smooth the flow of air at the time of air supply to reduce noise and increase the wind speed, the air supply pipe 22 and the air inlet pipe 30 At the end portion of)), the cross-sectional area of the air supply pipe is formed to be narrower, so that the internal wind speed of the air supply pipe 22 is faster, so that the inflow of external air by Bernoulli's theorem is more smoothly performed.

On the other hand, the spindle 24 for transmitting the power of the motor 23 to the impeller 21 passes through the air supply pipe 22 so as not to collide with the external air inlet pipe 30 during rotation, the air supply of the air supply pipe (11) should be connected to the end. Referring to FIG. 3, the end of the spindle 24 is connected to the impeller 21 by being split into a radiation shape to allow air to pass therethrough, and the end of the radiation shape is a blower blade shape to smoothly perform the performance during air supply. do.

First, when the air supply damper 13 is opened and the ventilation damper 15 is closed, the air supply mode is entered. This mode is activated during cooling or sterilization. In FIG. 4, since the lower air supply damper 13 is opened, the indoor air introduced through the exhaust port 11 by the rotational force of the impeller 21 is opened through the air supply pipe 22 of the impeller 21. To get out. At this time, the air flowing in the air supply pipe 22 by Bernoulli theorem has a lower pressure than the air outside the building, so that fresh air outside the building is introduced into the air supply pipe 22 through the outside air inlet pipe 30. Therefore, the air discharged into the room is supplied by mixing fresh air from the outside.

Second, when the air supply damper 13 is closed and the ventilation damper 15 is opened, the ventilation mode is entered.
