Description

[Detailed Description of the Invention] The present invention relates to a filter mounting device installed on the suction side of a heat exchanger in an air conditioner, ice maker, etc.

Conventionally, a filter mounting device shown in FIG. 4 has been commonly used. That is, in this figure, a is a heat exchanger placed on a bottom plate b, and on the air intake side of the heat exchanger a are a cut and raised piece b' of the bottom plate b and a bent piece c' of the top plate c. A pair of upper and lower grooves d and e having a predetermined interval 1 are formed by this, and a filter f is inserted and supported in these grooves d and e. Of the grooves d and e, the upper groove d is deeper than the lower groove e, and the upper side of the filter f is inserted into the upper groove d (indicated by a dashed line in the figure), and then the lower side is inserted into the lower groove. It is inserted into the groove e and supported in a detachable manner. However, in this configuration, if the height of the heat exchanger a is sufficiently high, that is, the distance between the upper and lower grooves d and e is sufficiently wide, there will be no problem in attaching and detaching the heat exchanger. If the distance between the upper and lower grooves d and e is low (small size) and the distance between the upper and lower grooves d and e is insufficient, attachment and detachment cannot be performed unless the distance 1 between each of the grooves d and e is made large. If the interval l between the grooves d and e is made large, it will naturally cause rattling when the filter f is inserted and supported, and the filter f will also generate noise due to the vibrations of the compressor, blower (not shown), etc. There was a problem, and there was also a fear that the filtration effect, which is the role of the filter f, would be reduced.

The present invention has been made to provide a filter support device that eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings using an ice maker as an example.

In the figure, 1 is the ice maker body, which is composed of an outer box 2, an inner box 3, and a heat insulating material 4 filled between the boxes 2 and 3, and the interior is divided into an ice making/ice storage room 5 and a machine room 6. ing. The machine room 6 houses a compressor 7, a condenser 8 (heat exchanger), a fan motor 9, etc. that constitute a cooling cycle. In addition, the ice making/ice storage chamber 5 is equipped with a top table 10 having heat insulation properties on the top surface, and a top table 10 having heat insulation properties on the front surface.
It is equipped with a front plate 11 that can be attached and detached with screws (not shown) and a door 12 that can be opened and closed.

The machine room 6 is divided into a bottom plate 13, an outer box 2, and a grille 14 detachably provided in the front opening, and the condenser 8 is placed and fixed on the bottom plate 13. Reference numeral 15 denotes an upper plate that covers the upper surface of the condenser 8. The upper part of the air intake side of the condenser 8 by the fan motor 9 is bent to form a bent piece 16, and the bent piece 16 and the condenser 8 are connected by a lever. An upper groove 17 is formed between the upper part of the front surface and the upper part of the front surface. Opposed to this upper groove 17, a lower groove 19 is formed at the lower front of the condenser 8 by a cut and raised piece 18 of the bottom plate 13, and these upper groove 17, lower groove 1
The upper and lower sides of the filter 20 are inserted and supported between the 9 spaces. Reference numeral 21 denotes a concave portion located in front of the lower groove 19 and recessed downward from the filter 20 mounting surface of the bottom plate 13, which is slightly longer than the width of the filter 20, and is integrally formed with the bottom plate 13 by press working or the like. It has been formed. The lower side of the filter 20 passes through this recess 21 when the upper side of the filter 20 is inserted into the upper groove 17 and the lower side is inserted into the lower groove 19, so that the upper side of the filter 20 is not inserted into the deep part of the upper groove 17. (Indicated by a dotted line in the figure) to allow it to be installed. Therefore, the width of the groove 17 (r)
The filter 20 can be inserted even if it is sufficiently narrow (slightly wider than the thickness of the filter 20).

As is clear from the above description, according to the present invention, since a recess is formed through which the lower side passes when the filter is inserted into the upper groove, the width of the groove into which the filter is inserted and supported is small. The filter can be inserted even when the filter is in use, and the filter does not rattle or lose its filtration effect.
