Abstract

The present invention relates to a ventilator, in which a damper function is activated when the ventilator is operated, and a damper is operated only when the ventilator is operated without providing a separate damper.

Description

[0001] The present invention relates to a ventilator with a damper function,

The present invention relates to a ventilator, in which a damper is operated only when the ventilator is operated without a separate damper being operated in order to operate the damper function.

Currently, the ventilator is installed in a wall or ceiling of a building such as a bathroom or a toilet, forcibly sucking the air, and discharges the air to the outside of the building through a duct or a duct.

In addition, the ventilator is usually provided with a damper directly or indirectly connected to the duct in order to discharge the turbid air. When the ventilator is not driven, the ventilator closes the ventilator and opens when the ventilator is operated.

Generally, the damper is divided into a general damper and an electric damper. In recent years, an electric damper combination type in which an electric damper is connected to a ventilation fan for sucking and discharging air is used. The electric damper, however, And the opening / closing of the exhaust duct is controlled by controlling the shaft turning operation of the disk-shaped shutter by using a motor rotating in the reverse direction, and in particular, the circuit portion for driving the electric damper is configured to be completely independent of the circuit portion for driving the ventilation fan So that the external power source, which is not rectified, is inputted to the electric damper, and then the electric power is decompressed and rectified to a voltage suitable for driving the motor through a circuit provided in the electric damper. A transformer for reducing the voltage when the voltage is AC 220 V, and a transformer for converting the reduced AC current into full- Which is a problem in that a diode bridge, and a constant-voltage IC and the electrolytic capacitor to the conversion by the diode bridge is a direct current to flow at a constant voltage should be installed as necessary.

Therefore, in recent years, a power-integrated type has a circulation pipe and a discharge pipe in two directions on the same axis xx which is displaced to one side of the ventilator case, and is connected to the circulation pipe and the discharge pipe, And the damper pipe of the power damper is connected to the circulation pipe and the discharge pipe respectively and the mounting piece of the damper pipe is attached to the mounting portion and the power cable of the ventilator and the power damper and the power cord are embedded in the control box inside the case And the electronic control circuit is integrally electronically controlled.

However, this structure also has a damper operation and a ventilator operation separately, as well as a separate operation structure, which causes a structural complexity and causes a failure.

Accordingly, in the present invention, the damper is integrated with the body case constituting the ventilator, and when the ventilator is operated, the damper is opened and when the operation is stopped, the damper is closed.

For this purpose, a movable shaft protruding forwardly to extend from a motor shaft for rotating the fan of the fan is formed. When the movable shaft rotates, the damper is opened. When rotation is stopped, the damper automatically closes.

The movable shaft is provided with a thread for opening the damper when rotating, and the movable part, which is engaged with the movable shaft, is formed as a fixed part and a fixed part so that the fixed part is connected to the damper. When the damper is opened, It is to maintain the state.

In addition, when the movable shaft is stopped, the spring can be automatically closed by the restoring force of the spring in a state where the spring is pressed when the damper is opened.

In addition, the damper can be precisely opened and closed by the engagement of the guide shaft and the guide shaft groove for accurate opening and closing operation, and the spring can be accurately mounted to the guide shaft.

In addition, the damper is assembled with a separate cover plate for ease of molding, thereby providing ease of manufacture.

Accordingly, when the fan of the ventilator is rotated, the movable plate engaged with the screw thread is rotated forward and backward while the movable shaft is rotated, so that the damper interlocked with the movable plate is opened and closed, so that the operation can be stably and accurately maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 13, the structure of the present invention includes a motor 10 mounted on the outside of the case body 20 for rotating the fan 11 of the fan, A motor shaft 12 is provided to rotate the fan 11 to discharge the turbid air of the motor 11 and a fan 11 mounted on the motor shaft 12 is accommodated, A case body 20 having a suction port 21 for sucking in room air that is turbid when rotated, and a case body 20 which is built in the case body 20 and protrudes forward of the fan 11 so as to extend to the motor shaft 12 The movable part 40 and the movable part 40 which move the damper 30 to open and close while moving back and forth when the movable shaft 13 and the movable shaft 13 rotate are rotated by the rotation of the movable shaft 13, When the fan 11 is stopped in a state in which the electric charger 41 and the damper 30 are turned to rotate in a state where the fan 30 is opened, 10 is consists of a guide shaft 22 and a spring 23 mounted on the guide shafts 22 to to the damper 30, which been opened when the movable shaft 13 is stopped is closed automatically as stop.

In this case, the case body 20 is generally injection-molded into a plastic to prevent corrosion and to realize a low weight. The motor 10 is mounted so as to be exposed to the outside of the case body 20, will be.

The damper 30 is provided with a guide shaft groove 31 through which the guide shaft 22 formed in the case body 20 can be fitted. 32 is formed with a coupling shaft groove 34 to which the coupling shaft 33 of the coupling shaft 32 can be coupled.

Therefore, the damper 30 is formed by combining the base portion 35 and the blocking plate 32 so that the base portion 35 can be easily formed and the blocking plate 32 can be easily coupled to the damper 30, The damper 30 can be easily opened and closed even when the power of the motor 10 is low due to the low weight of the base portion 35. [

The movable shaft 13 for opening and closing the damper 30 according to the present invention is provided with a thread 13a having a predetermined length corresponding to the opening and closing range of the damper 30 at the tip thereof, The movable part 40 engaged with the thread 13a is engaged with the damper 30 and the electric motor 41 to rotate only the electric part 41 engaged with the electric field part 41, And a fixing part 42 connected thereto.

Therefore, the fixed portion 42 engaged with the electric power generating portion 41 is rotated in the state of being connected to the damper 30, 13 so that the damper 30 can be opened and closed.

The damper 30 is opened in a state that the fixing part 42 is advanced by being connected to the bearing 43 and the electric power is maintained in the state that the damper 30 is opened as described above Only the magnetic field part 41 is rotated while being engaged with the movable shaft 13.

When the damper 30 is opened and the rotation of the fan 11 is stopped, the movable shaft 13 is stopped. When the damper 30 is opened, the pressed spring 23 returns The damper which has been moved forward is rotated while being rotated by the bearing 43 in the fixed portion 42 by the movable shaft 13 and is closed will be.
