Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a ventilation fan that discharges oil smoke generated during cooking to the outside.

Conventional technology In general, ventilation fans in the kitchen that exhaust oil smoke generated during cooking to prevent indoor air from becoming polluted become heavily contaminated due to the oil smoke adhering to them.
It is necessary to clean frequently. In order to save this cleaning effort, conventional ventilation fans of this type have a cover 106 that has a fan guide section provided on the intake side of a frame 101 that is inserted and attached to a kitchen wall (not shown), as shown in FIG. A filter frame 1 in which a filter 107 is housed is provided in front of the cover.
08 was established. Further, as the filter 107, punched metal is often used because it has good efficiency in collecting oil smoke and is easy to clean.

Problems that the invention attempts to solve In such a conventional configuration, the filter 107
When cleaning the filter frame 108, the filter frame 108 is removed from the cover 106. However, since this type of ventilation fan is installed at a high location, cleaning requires the installation and removal of multiple parts. This was not an easy task. For that reason, the 6th
As shown in the figure, a method has been proposed in which the filter 110 is integrally molded into a resin filter frame 111 to form a single component, but since resin has a higher shrinkage rate than metal, the resin filter frame portion shrinks. ,
There was a problem with the filter being distorted due to pushing on the edge of the filter.

The present invention takes these conventional problems into consideration, and aims to provide a ventilation fan having a filter that does not distort even when the filter and the filter frame are integrally molded as one part.

Means for solving the problem In order to solve this problem, the present invention provides a filter on the intake side of the frame housing the motor and blades, and this filter is made of corrugated punched metal and made of resin. The filter frame is integrally molded with the filter frame, and the end portion of the punched metal on the side perpendicular to the ridgeline direction of the corrugation is attached so as to penetrate the filter frame.

Effect With this configuration, when cleaning dirt on the filter, since it is integrated with the filter frame, it is only necessary to remove one part; Since the part passes through the filter frame, even if the filter frame contracts, it does not push the end face on the side perpendicular to the ridgeline direction, and the force applied to the end face on the side parallel to the ridgeline direction is reduced by the waveform shape. Therefore, the filter will not be distorted.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In the figure, reference numeral 1 denotes a corrugated punching metal. Both sides parallel to the corrugated ridgeline are embedded in a resin filter frame 2, and the end perpendicular to the corrugated ridgeline is made to protrude through the filter frame 2 to form the filter frame. 2 is integrally molded.

Next, this integral molding will be explained. When the filter 1 is integrally molded with the filter frame 2, the second
The filter frame 2 contracts in the direction of the arrow shown in FIGS. Filter frame 2 in the direction of the filter ridgeline
When the filter 1 contracts, the end of the filter 1 is exposed beyond the filter frame 2 by the length of the filter frame 2 as shown in FIG.
is not affected by the contraction of the filter frame 2.

On the other hand, when the filter frame 2 contracts in a direction perpendicular to the ridgeline of the filter 1, the filter frame 2 compresses the filter 1 in the direction of the arrow as shown in FIG. As shown in the figure, the shape of the filter 1 before compression, shown by the solid line, becomes the shape of the filter 1 after compression, shown by the broken line. is not distorted due to the effect of contraction of the filter frame 2.

Effects of the invention As is clear from the description of the embodiments above, according to the invention, when the filter and filter frame are integrally molded, the filter can be manufactured without distortion, and it is also possible to clean the dirt on the filter. In some cases, the filter and filter frame are integrated, which makes the work easier.
