Description

[Detailed Description of the Invention] The present invention relates to a filter disposed at the air intake port of an air conditioner such as a heater, and is intended to improve economic efficiency and maintainability.

In general, this type of filter has a shape-retaining frame 12 made of resin and integrally formed with a filter cloth 11 such as a non-woven fabric, for example, by molding the same at the same time as forming the frame, as shown in FIG.

Although such a filter has good productivity, if the filter cloth 11 becomes extremely clogged due to continued use without cleaning for a long period of time, for example, the entire filter including the shape-retaining frame 12 must be discarded. First, there was a disadvantage that it was impossible to replace only the filter cloth 11, which was not economical.

Furthermore, even if one wishes to wash the filter cloth 11 with water to remove dirt, it is not possible to wash the filter cloth 11 by putting it in a washing machine or the like, which is troublesome and requires the user's hands.

The present invention eliminates these conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

The drawing shows a case where the device is used as a radiator. 1 is a main body, 2 is a front plate thereof, and has an inlet 3 at the top and an outlet 4 at the bottom.

5 is a heat exchanger provided in the main body 1, and a hot water pipe 5a
It is constructed by providing fins 5b on the fins 5b.

Reference numeral 6 denotes a blower fan which sucks indoor air, exchanges heat with the heat exchanger 5, and then blows it into the room.

7 is a filter disposed on a portion of the heat exchanger 5 facing the suction port 3, which includes a filter member 7a and a shape-retaining frame 7b.
It consists of.

The filter member 7a is made of a breathable non-woven fabric such as polyester, and can be formed into a bag-like shape with openings 8 at both ends by folding it into two pieces and sewing the edges together, as shown in FIG. be.

The shape-retaining frame 7b is formed by bending a metal wire into a rectangular frame shape, and is detachably inserted into the bag-shaped filter member 7a.

In the above configuration, the filter 7 can be separated into the filter member 7a and the shape retaining frame 7b, as is clear from the above configuration.

Therefore, if the filter becomes extremely clogged after continued use for a long period of time, the shape-retaining frame 7b can be removed from the filter member 7a and only the filter member 7a can be replaced.

Further, when cleaning the filter member 7a, the filter member 7a can be washed in a washing machine or the like by removing the shape retaining frame 7b.

In the above embodiment, the filter member 7a has openings 8 at both ends.
Although the opening 8 has been described as having a shape retaining frame 7b, either one of the openings 8 may be sewn into one, and any opening 8 may be used as long as the shape-retaining frame 7b can be attached and detached.

As described above, the present invention has great practical value, as only one filter member can be replaced and the shape-retaining frame can be removed for washing.
