Description

[0001] The present invention relates to an air blower with a damper,

The present invention relates to a damper-integrated blower, and more particularly, to a damper-integrated blower that can effectively block the backward wind and prevent damage to the damper and the motor repeatedly operated, thereby extending service life.

Generally, the building is provided with a ventilation device for ventilating the air in the enclosed room by discharging the contaminated air from the room to the outside and introducing fresh air outdoors to the room. In such a ventilation device, The total heat exchange type ventilation device including the total heat exchange element is widely applied so that the temperature of the room can be maintained while minimizing the temperature.

However, since the conventional ventilator includes a separate damper facility for shutting off the indoor and outdoor units during non-operation, it is difficult to manufacture the ventilator in a compact and slim form due to increase in the manufacturing cost and increase in the volume of the ventilator .

In order to solve such a problem, a damper blowing apparatus configured to open and close a discharge port by providing a vane to a discharge port of the blower has been proposed in the prior art (Patent No. 10-1559374).

However, in the broaching apparatus according to the prior art document, the sealing collar is formed on the outer circumferential surface of the gasket in order to block leakage of air into the gap between the shaft of the gasket and the shaft insertion groove. There is a fear of raising the load of the motor for applying the turning force and thus shortening the life of the motor. In this case, The sealing collar formed on the shaft may be deformed or damaged, which may increase the necessity of maintenance.

Further, when the gasket is rotated upwardly or downwardly, the closing lid coated on the vane is dragged on the left and right side walls and the bottom of the vent hole in the course of the rotation, and friction is generated so as to increase the load and shorten the life of the motor The repetition of such friction may cause deformation or damage of the sealing collar which is covered with the vane, which often causes maintenance disadvantages.

Patent No. 10-1559374: Damper blower

It is an object of the present invention to minimize the interference and friction between a rotating damper and a discharge port to prevent a load of a motor from rising and damage to a damper to the utmost, So that it is possible to improve the efficiency of blocking the reverse wind.

And a slit blocking diaphragm which is brought into close contact with the gap and blocks backflow flowing into the gap when the discharge port is closed.

In this case, a flap is upwardly protruded on the upper end of the gap shielding feathers, and a protruding groove is formed on the ceiling of the discharge port on the rear side of the shaft to receive the flap protrusion when the gap shielding collar is in close contact.

In addition, the left and right side walls and the bottom of the discharge port are provided with a closing protrusion corresponding to the closing position of the damper, and the closing feathers of the damper are spaced apart from the left and right side walls and the bottom of the discharging opening during upward or downward turning, So that the discharge port can be closed airtightly.

According to the damper-integrated blower according to the present invention,

It is possible to block the reverse wind efficiently through the closing collar. Especially, it is possible to completely block the backward wind which can flow into the gap between the damper shaft and the shaft groove for damper rotation through the gapping barrier formed in the damper, There is an advantage.

In addition, since the gap-blocking collar and the closing collar for damper for blocking the backward wind are in close contact with the inner surface of the discharge port only when the discharge port is closed, interference and friction with the inner surface of the discharge port do not occur in the rotation process for opening / closing the discharge port, There is an advantage that the damper motor can be rotated and the lifetime of the damper motor can be prolonged by preventing the damper motor from unnecessarily increasing the load or deforming or damaging the damper.
