Description

[Detailed Description of the Invention] The present invention relates to an improvement of a ventilation fan with a filter, and aims to reduce the number of parts, simplify the structure, and facilitate attachment and detachment of the filter.

Conventional ventilation fans with filters are shown in Figures 4 and 5.
A filter 103 is sandwiched between a front cover frame 101 and a filter holding frame 102, one end of the front cover frame 101 is hooked on an orifice 105 of a ventilation fan body frame 104, and the other end is elastically engaged with the orifice 105. It was installed.

An oil pack 106 that receives oil droplets dripping from the filter 103 is fixed to the orifice 105 so as to cover the lower surface of the front cover frame 101.

Therefore, when replacing filter 103, screw 107
, remove the oil pack 106, then remove the front cover frame 101 from the orifice 105, and then remove the filter holding frame 102 from the front cover frame 101 to remove the filter, making the filter replacement work very troublesome. there were.

Furthermore, since the oil pack 106, the filter holding frame 102, and the front cover frame 101 are each constructed as separate parts, there is a drawback that the parts are easily lost.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is a ventilation fan main body frame, and a fan motor 2 is installed inside.

A shutter 3 and an orifice 4 cover the outer periphery of the fan and are attached to the ventilation fan body frame 1.

Reference numeral 5 denotes a front cover frame having an opening on the opposing surface and an insertion hole 6 provided on the lower surface, and is attached to the front surface of the orifice 4.

Reference numeral 7 designates a resin-molded filter holding frame, on which a cross-sectional oil pan 8 is integrally molded over the entire width of the lower end, and a filter holding frame 9 is integrally molded so as to be bendable with the upper end as a fulcrum.

The filter holding frame 7 is inserted into the insertion hole 6, and the oil pan 8
It is attached by snappingly engaging the orifice 4 with a protrusion 10 provided on the outer periphery.

A filter 11 is held between the filter holding frame 9 and the filter holding frame 7.

In the above configuration, when replacing the filter 11,
By simply pulling the oil receiver 8 downward, the projection 10 is disengaged from the orifice 4, and the filter holding frame 7 can be easily removed from the front cover frame 5.

Moreover, since the filter holding frame 7, filter holding frame 9, and oil pan 8 are integrally molded, there is no need to disassemble the filter to replace it and to worry about losing parts.

As described above, according to the present invention, the filter holding frame that holds the filter, the filter holding frame that holds the filter in the filter holding frame, and the oil receiver that receives the oil dripping from the filter are integrally molded, unlike conventional products. This eliminates the disadvantage that the above-mentioned parts are easily lost and cannot be assembled because the parts are configured separately.

In addition, since the number of parts is extremely small, assembly is easy.Furthermore, the filter holding frame, oil pan, etc. can be inserted and removed from the bottom of the front cover frame, and the filter holding frame can be attached or removed by pulling out the frame, so the oil pan can be tilted. without any
It can be removed from the front cover frame.

Therefore, the practical value is extremely high, as the oil accumulated in the oil pan will not spill out and contaminate the surrounding area during removal.
