Description

[0001] Slide Prefabricated exhaust fan [0002]

The present invention relates to a ventilator used in a bathroom or the like for discharging contaminated air to the outside. More specifically, the fixing flange is separated from the main body of the ventilator, and the ventilator is slidably assembled. The present invention provides an improved ventilation fan that can be easily assembled and can also provide ease of maintenance.

Generally, ventilators for air conditioning are installed in various buildings of a residential or industrial area. Such ventilators include a fan driven by a motor and installed in the ceiling of a building, and a duct unit For example, a flexible tube and a diffuser).

In the conventional ventilator structure, a fan rotated by a motor is installed in a substantially square-box-shaped ventilator main body, a vent is formed in the side wall of the ventilator main body, a flexible tube is connected to the ventilator, A ceiling panel and a flange which is tightly fixed to the ceiling panel.

In the case of the above-described ventilator, there is no great difficulty in installing the ventilator by simply installing it for ventilation. However, in recent years, ventilators used in residential bathrooms have adopted a structure in which an electric damper is installed at the outlet side.

In such a case, since the electric damper is assembled, it is impossible to install the electric damper. Therefore, the electric damper is mounted on the upper side of the ceiling panel and assembled with the ventilator.

For example, in the case of a ventilator employing an electric damper, as disclosed in Korean Utility Model Publication (U) No. 20-2012-0006871 (Oct. 8, 2012) When the fan body is pushed up in a state that the lower end of the sliding plate of the discharge pipe connected to the flexible pipe body is sandwiched between the guide rails in the structure in which the rails are formed and the sliding plate is formed on the discharge pipe (member corresponding to the electric damper) So that the discharge pipe and the fan body can be assembled. However, in this case, when the sliding plate naturally flows along the guide rail along the guide rail at the time of field installation, the sliding plate can be lowered by applying an impact to the fan main body.

On the other hand, a ventilator without a flange has been proposed, for example, a ventilator disclosed in Korean Patent Registration No. B1-0101085 (Oct. 3, 2008).

In the case of the above-described ventilator, the ventilator may include a suction port formed to be opened toward the inside of the building and connected to the suction port through which the indoor air is sucked, and a discharge port that is opened toward the outside of the building and discharges the sucked indoor air. ; A driving motor mounted inside the case and generating a driving force by receiving power; And a rotating fan coupled to a rotating shaft of the driving motor and rotating by the driving force to suck indoor air and discharge the indoor air to the discharging port. The rotating fan is embedded in an installation hole formed in a ceiling and a wall surface of a building, 1. A ventilator for sucking air and discharging the air to the outside of the building, comprising: at least one second screw mounted on a bottom surface of the case; And one or more engaging pieces which are threadedly formed to penetrate the second screw so as to be engaged with the second screw and which are mounted on the bottom surface of the case, the engaging pieces being engaged with the second screw, And rotates by 30 to 180 degrees in the lateral direction to protrude and retract into the side wall of the case to support the outside of the rim of the mounting hole.

According to the present invention, the case can be easily installed by mounting holes formed in the ceiling in the state where the electric damper is coupled as in the present invention. However, in order to fix the case to the ceiling, There is a problem that work to move the projections and work to rotate the engaging pieces to be transferred to the bottom surface of the ceiling panel are poor.

KR 2020120006871i 2012.10.08. KR 100791085 B1 2008.10.03.

Therefore, the inventor of the present invention has found that when the ventilator is installed with the installation hole formed in the conventional ceiling panel, the installation difficulty is difficult due to the difficulty of coupling the electric damper to the outlet of the ventilator, and when the ventilator and the electric damper are installed, The present invention has been researched and developed.

In other words, in the present invention, in configuring the ventilator, the fixing flange is configured to be detachable from the ventilator main body, and the coupling between the ventilator main body and the fixing flange can be made by a sliding method. In a state where the ventilator main body and the fixing flange are integrally joined The ventilator main body is sandwiched between the installation holes formed in the ceiling panel and the ventilator main body is slid in a state that the fixing flange is fixed to the ceiling panel so as to secure the working space and then the electric damper can be assembled and fixed to the ventilator main body, The present invention has been accomplished on the basis of the technical object of the present invention with the provision of a slide assembly type ventilator which can simultaneously improve the installation performance of the electric damper and the maintenance property thereof.

In order to achieve the above object, according to the present invention, a fan driven by a motor is installed inside a main body of a fan, which is inserted into an installation hole formed in a ceiling panel, and a fan is installed to be fixed to the ceiling panel, A fixing flange is provided on the main body and the inner lid is closely fixed to the lower side of the fixing flange and the inner lid is coupled to form an inflow space between the inner lid and the inner lid, And an electric damper connected to a flexible exhaust pipe or a flexible exhaust pipe at a discharge port formed in the main body of the fan, The ventilator main body and the fixing flange are separated from each other and are slidably coupled to each other. The ventilator main body is provided with a slide projection protruding outward at the lower ends of both side walls in a direction perpendicular to the coupling of the flexible exhaust pipe or the electric motor driven by the flexible exhaust pipe. The flange is formed with slide protrusions facing each other so as to be exposed to the top of the ceiling panel, and the slide protrusions are formed with slide grooves through which the slide protrusions are inserted.

In a ventilator having a second electric damper, The slide protrusions are formed on the lower ends of both side walls of the fan body in a direction perpendicular to the direction of the electric motor connected to the flexible exhaust pipe or the flexible exhaust pipe and the slide flanks are formed on the fixing flange so as to face the slide panels, And the slide protrusion is formed so that the slide protrusion is inserted into the slide protrusion so as to be upwardly opened.

Third, the slide groove is characterized in that the upper and lower protrusions are formed in a zigzag shape.

Fourth, the main body and the fixing flange are formed with a shield plate for the main body and a shield plate for the flange at a right angle to the slide protrusion and the slide groove, respectively, so that the water tightness can be increased.

Fifth, the fan fixture is formed to protrude inwardly from the main body of the fan and the fixing flange respectively, and the pieces can be fixed to each other at the fixing flange side fixture.

Since the fan body and the fixing flange are separated from each other when the slide assembly type fan provided in the present invention is used, the fan body is assembled to the upper side of the ceiling panel in the assembled state and then slid to one side and then the electric damper is assembled. And can be easily separated in the reverse order for repairing them, so that convenience of maintenance can be provided.
