Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation fan used in a kitchen of a general household, and more particularly to a ventilation fan provided with a filter on its front surface.

2. Description of the Related Art Conventionally, this type of ventilation fan generally has a configuration as shown in FIGS.

That is, a motor 102 is horizontally supported by a support arm 103 in a frame body 101 that is inserted into a hole provided as a ventilation hole in a vertical wall and attached, and a blade 104 that sends air out of the room is fixed to the motor 102. A shutter 105 is provided on the exhaust side of the frame 101 to close when the ventilation fan is stopped, a cover 106 having a fan guide portion is provided on the intake side of the frame 101, and oil dust is trapped on the front surface of the cover 106. The filter frame 107 has a filter frame 107 to which a collecting filter 108 is detachably attached.
An oil pan is detachably attached to the lower part of the.

The filter 108 of the ventilation fan configured as described above was attached to the filter frame 107 as described below.

First, with the filter 108 in an inclined state, the upper end portion thereof is inserted into the insertion groove of the lower opening formed in the upper portion of the filter frame 107, and then the filter 108 is rotated so as to be pressed to the filter frame 107 side. The filter frame 10 on both sides.
Insert into the insertion groove of the front opening formed on both sides of 7.
Then, the filter 108 is pulled down, and the lower end thereof is inserted into the insertion groove of the upper opening formed in the lower portion of the filter frame 107, and the mounting of the filter 108 is completed.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional ventilation fan, since the filter 108 is only inserted into the insertion groove of the filter frame 107, the filter 108 rattles and the entire circumference of the filter frame is covered. There was a danger that even if a part of it was not fully inserted into the insertion groove, it would fall. Also, the filter 108
A gap may be formed between the filter frame 107 and the filter frame 107, and oil may adhere to the gap to make it difficult to remove the filter 108.

The present invention solves the above problems, and an object of the present invention is to make it possible to easily and surely attach and detach a filter to a filter frame without any gap or rattling.

Means for Solving the Problems In order to achieve the above object, a ventilation fan of the present invention has a frame body attached to a vertical wall, a motor supported by a support arm in the frame body, and fixed to the motor. With feathers,
A cover having a fan guide portion provided on the intake side of the frame body, a filter frame detachably provided on the front surface of the cover, an oil receiver detachably attached to a lower portion of the filter frame, and the filter. And a filter detachably provided in the frame, the filter frame has a fixing hole opened upward on both side surfaces, the filter is formed in a shape to wrap both side surfaces from the front surface of the filter frame, It has vertically long fixing claws integrally formed on both upper ends of both sides and protrudes downward. To remove the filter frame and the filter from each other to form a ventilation fan.

The present invention has the above-described structure. When the filter is attached to or detached from the filter frame, the filter fixing claw and the filter frame fixing hole are fitted by sliding the filter vertically on the frame portions on both front surfaces of the filter frame. Since they are fitted or removed, they are easily and reliably carried out, and they can be mounted without a gap.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in the drawing, a frame 1 having an opening on the indoor side and an outdoor side is inserted and attached into a hole provided as a ventilation port in a vertical wall of a house. Inside the frame body 1, a motor 3 having blades 4 fixed thereto is horizontally supported by a support arm 2. Further, a shutter 5 is provided on the exhaust side which is the outdoor side of the frame body 1, and a cover 6 having a fan guide portion is provided on the intake side which is the indoor side. Locking claws 7 are provided on the upper and lower portions of the cover 6, and a filter frame 9 having a locking hole 8 that engages with the locking claws 7 is detachably provided on the front surface of the cover 6. There is. The filter frame 9 is provided with fixing holes 11 opening upward on both side surfaces, and a filter 10 having fixing claws 12 fitted into the fixing holes 11 is detachably provided. The fixing claws 12 are integrally formed in a vertically long shape so as to project downward at the upper ends of both ends of the filter 10 formed in a shape that wraps the front surface and the both side surfaces of the filter frame 9.
The shape and dimensions are determined so that the filter can be fitted in or removed from the fixing holes 11 of the filter frame 9 by sliding the filter vertically on the frame portions on both sides of the filter frame 9.

To mount the filter 10 of the ventilation fan in the above configuration, when the filter 10 is pressed against the frame portions on both sides of the front surface of the filter frame 9 and slides downward, the fixing claws 12 cause the fixing holes 11 of the filter frame 9 to move.
It fits naturally and is completed with just this operation. Further, the fitting between the fixing claw 12 and the fixing hole 11 is strong and stable because the fixing claw is vertically long and the fitting dimension is long, and this fitting causes the filter 10 to fit the filter frame 9 The filter 10 is mounted on the filter frame 9 without any gap or rattling because it is carried out while sliding on the frame part.

On the other hand, when the filter 10 is removed from the filter frame 9, contrary to the above, the filter 10 is pushed up so as to slide upward on the frame portion of the filter frame 9, and the fitting claw 12 and the fixing hole 11 are fitted together. Is not in a place where a large amount of oil adheres, and
The filter 10 is easily removed because it is not shaped so that oil will collect and stick. The fixing claw 12 formed integrally with the filter 10 may have a dowel on its side surface so that the filter 10 does not come off during operation of the ventilation fan.

EFFECTS OF THE INVENTION As is apparent from the above embodiments, according to the present invention, the filter can be easily and reliably slid on the filter frame by sliding the filter vertically on the frame portions on both sides of the filter frame. It is removable, and when the filter is attached to the filter frame, the fixing claw of the filter and the fixing hole of the filter frame are fitted while sliding the filter on the frame portions on both front surfaces of the filter frame. Since the filter is mounted on the filter frame without any gap, and the fixing claw is vertically long and the fitting dimension is long, the fitting force is strong and stable, and the rattling of the filter is eliminated.
