Abstract

PURPOSE:To permit to assemble each parts, accommodated in a frame body for the ventilator, before incorporating a supporting body into the frame body by a method wherein shutters are supported by bearings to the supporting body, supporting a motor to the inside of the frame body for the ventilator. CONSTITUTION:The ventilator 1 consists of the cylindrical frame 2 of the ventilator, a ventilating decoration grille 3 attached to the indoor side opening of the frame body 2 and the peripheral rim thereof is abutting against the surface of the wall of the opening, the supporting body 5 attached to the inside of the frame body 2 by a screw 4, the motor 7 attached to the supporting body 5 by the screw 6, a blade 8 attached to the rotating shaft of the motor 7, two sheets of shutters 9U, 9D supported to the supporting body 5 by the bearings and opened or closed freely in the frame body 2 and a bow type attaching and holding spring 10 attached to the outside surface of the frame body 2 by the screw 4 fixing the supporting body 5. Accordingly, the attaching and removing of said shutters 9U, 9D may be effected easily by withdrawing the frame body 2 from said supporting body 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation system having an improved structure.

Conventionally, the shutter attached to a ventilation system was pivoted to a pivot formed on the side wall of the opening at one end of the ventilation system frame. Although the number of parts is reduced, the G-shape of the frame cannot be easily formed.

In view of the above points, it is an object of the present invention to provide a ventilation system that can be easily molded without increasing the number of parts and improves work efficiency. By supporting the V? -s has been completed.

Hereinafter, as shown in FIGS. 1 to 8, the present invention will be described as a ventilation device which is used by being inserted into a cylindrical opening formed in a wall. I will clarify.

The ventilation device (1) includes a cylindrical ventilation device frame (2), a ventilation decorative grill (3) that is attached to the inner opening of the frame (2), and whose peripheral edge is in contact with a wall surface, and the frame. (2) Attach the screw +411c to the circle 1. a support (5), a screw (7) attached to the support (5) with a screw (61), a blade (81) attached to the rotating shaft of the motor (7); The frame body (2 shirts t9vlt9D) is pivoted to the support body 15), and the frame body (2) is attached to the frame body (2) by the screws (4) which completely fixes the support body (51). A retaining spring (10) with a bow-shaped blowout 1 attached to the outer surface and (-n
Become. The frame body ('3), the ventilation decorative grille (3), and the blades (8) are molded from synthetic resin.The support body (5) is molded using a sheet metal press, and has a substantially inverted triangular shape. It is molded into a shape with an arcuate cutout at the edge. The corner portion Vc of the triangular supporting body (5) is connected to the frame body (
2) A screw hole Qll'i into which the screw (41) is screwed is formed so that the circle IIo#lc comes into contact with the circle IIo#lc, and a bent portion tt21' is formed.

An extension part cI31 is formed at the lower corner of the support body (5) and extends to the opening of the frame body (2) at the bent part (13). An elastic body (14t) is attached to the support body (5).The moat (7) is attached to the center part of the support body (5), and the reason for this attachment is that the elastic body (14t) The notch a formed in the upper part of the inverted triangular support (5)
9 A shutter pivot 161 is provided at the inner edge of both ends and the center of both side edges.
Bearing hole that supports f171 Σ (18109t-shaped 7j protrusion QOI
6!1) It is shaped. The upper edge VC of the protruding piece (C) formed on both side edges of the support body (51) is connected to the shutter (9D).
The shutters (ν'F') (9D) are each shaped like a dairy cow's disc, and are formed with a protrusion @ that comes into contact with the shutter when it opens to restrict its opening. A disk sufficient to close the frame body (21) is formed.A shaft insertion hole is formed in the shutter (9o) u located on the lower side, and in the portion of the straight portion of the upper edge of the shutter (9o) that faces the protrusion (c). The shutter (9D) is pivotally supported on the support (5) by inserting the formed cut-and-raised piece (C) into the shaped hole lJg+ and the shaft insertion hole of the cut-and-raised piece (C). 911 below the arcuate edge of the shutter (9D)
A straight notch (2) is formed in the 11th part of the shutter (9D) to prevent the shutter (9D) from hitting the inner surface of the frame (2) when the shutter (9D) is opened or closed. An elastic body (2) is attached to the upper edge of the shutter (9DM'). The shutter (9+) located on the upper side has a shaft insertion hole @ formed in the portion facing the projection piece a (201) on both sides of the upper portion of the upper arcuate portion of the upper edge of the shutter (9+).
It is shaped like 1gJ and cA. The shutter axis tt
e t By inserting it into the spare hole U & of the 9iA piece (2)) and the shaft insertion hole (A) of the cut and raised piece @, the shutter (9
#-) is pivotally supported on the support body (5), and bent portions (4) are formed entirely on both sides of the arcuate edge of the shutter (9?=). The bent portion fA abuts the opening edge of the frame (2) at nine o'clock when the shutter (9) is opened, and the shutter (9) is smaller than the case where the bent portion is not fully formed. This increases the opening angle of the In addition, the bent portion 4 can be cut out or machined into the bent portion as described above.
The contact with the frame (2) is soft. The shutter pivot u61 frame connects the support body (5) to the frame body +
When the 2+vcP3 mounting 7 is installed, its end portion is located close to the inner surface of the frame 12), thereby preventing removal. Therefore, the shutter (9 yen) (9D) can be removed by moving the support (5) in and out of the frame (2).
It's easy to do.

As mentioned above, the addition of the shutter (941) (9D) can be easily removed! By changing the insertion direction of the A air device 11) into the opening formed in the wall, the J
It is very convenient when used for JVR and intake.

In this embodiment, the support (5) has a substantially inverted triangular shape, but it can also be made into a cross shape, etc., and may be made of synthetic resin.

As described above, in the present invention, the shutter is pivotally supported on the support body that attaches the motor to the frame 1η, and the mounting part of the shutter can be easily formed without increasing the number of parts, and the assembly efficiency is improved. Effects such as golden odor °t7).
