Description

[Detailed Description of the Invention] This invention relates to a filter guide fixed to the back surface of the suction grill of an air conditioner in order to mount an air filter on the back surface of the suction grill.

Figures 1 and 2 are drawings showing a wall-mounted indoor unit main body A of a separate air conditioner, in which 1 is the front panel, 2 is the rear panel, 3 is the upper part on the rear panel 2 side, and the lower part This evaporator is installed in an inclined state within the indoor unit main body A so as to be located on the front panel 1 side.

4 is a fan arranged in a space formed below the indoor unit main body A by installing the evaporator 3 at an angle inside the indoor unit main body A; 5 is a suction grill provided at the top of the front panel 1; , 6 are air outlets provided at the lower part of the front panel 1.

7 is a drain pan for receiving water condensed on the evaporator 3; 8 is a drain pipe for draining the water in the drain pan 7 to the outside; 9 is a refrigerant pipe connecting the outdoor unit (not shown) and the evaporator 3; be.

Then, by rotating the fan 4, the air sucked in from the suction grill 5 is cooled by the evaporator 3, and this cooled air is blown out from the outlet 6, thereby cooling the room in which the indoor unit A is installed. It has become.

By the way, on the back side of the suction grill 5 of the indoor unit main body A as described above, an air filter 10 made of a resin mesh or the like stretched over a rectangular frame is attached. It adsorbs dust and dirt contained in the air sucked in from the grill 5, and prevents the dust and dirt contained in the air from flowing into the indoor unit main body AX.

The air filter 10 is attached to the back surface of the suction grille 5 in the following manner.

That is, as shown in FIGS. 3, 4, and 6, a pair of vertical bars 11 and a vertical bar 1 are arranged in parallel at a certain interval.
As shown in FIGS. 5 and 6, a filter guide 13 consisting of a guide board 12 provided perpendicularly to the vertical bar is attached to the back edge of the suction grill 5 formed on the front panel 1. A plurality of screws (three in the drawing) are fixed in the vertical direction, and the filter guide 13 is connected to the back surface of the suction grill 5.
A groove 14 extending vertically is formed on the back surface of the suction grill 5.

The air filter 10 is installed on the back surface of the suction grille 5 by fitting both ends of the air filter 10 into the grooves 14.

The air filter 10 is attached to and removed from the suction grille 5 from the upper peripheral edge of the outlet grille 6 located below the suction grille 5.

However, when the filter guide 13 is installed over the entire length of the back surface of the suction grill 5 in the vertical direction as described above, in order to make the depth of the indoor unit main body A as thin as possible, the suction grill 5
When the evaporator 3 is placed close to the evaporator 3, the lower part 3a of the evaporator 3 installed in an inclined state on the indoor unit main body A is attached to the guide substrate 1 of the filter guide 13 attached to the back surface of the suction grill 5.
I come into contact with 2.

For this reason, even though there is a sufficient gap between the upper part of the evaporator 3 and the suction grill 5, the suction grill 5 and the evaporator 3
There was a problem that they could not be placed very close to each other.

In view of the above-mentioned problems, this invention involves cutting out a predetermined portion of the guide board of the filter guide, which is installed at predetermined intervals in the vertical direction on the back of the suction grill, that is, a portion adjacent to the evaporator located behind the suction grill. This provides a filter guide in which the evaporator can be brought as close as possible to the suction grill.The details of this invention will be explained below with reference to the embodiments shown in the drawings.

Figures 7 to 10 show a filter guide 2 according to this invention.
0, in which reference numeral 21 indicates a pair of vertical bars 21 arranged in parallel at a constant interval, and the pair of vertical bars 21 are connected to each other at the upper and lower ends.

Reference numeral 22 denotes a guide board formed on the back edge of the vertical bar 21 so as to be perpendicular to the vertical bar 21, and this guide board 22 is provided in two places: a part located above the middle part of the vertical bar 21, and a lower part. The guide substrate 22 is not formed in the part of the filter guide 20 that is closest to the evaporator, and 23 is a reinforcement provided in the part between the pair of vertical bars 21 where there is no guide substrate 22. The surface of the bottom plate 23 is shaped so as to be located on the same plane as the edge of the vertical beam 21.

Reference numeral 24 denotes through holes provided at the upper and lower ends of the filter guide 20, through which screws for fixing the filter guide 20 to the suction grill pass.

Reference numeral 25 indicates that the filter guide 20 is fixed to the back surface of the suction grille, and when the recessed groove 14 is formed by the back surface of the suction grille and the filter guide, in order to guide both ends of the air filter into the recessed groove 14, there are provided at the lower part of the guide board 22. This cut-and-raised portion 25 is provided at the lower end of each of the two guide substrates 22 provided on the filter guide 20.

As shown in FIGS. 11 and 12, the filter guide 20 configured as described above is installed in the vertical direction on the back surface of the suction grill 5 provided on the front panel 1 of the indoor unit main body A, as shown in FIGS. 11 and 12. The suction grille 5 and the filter guide 20 are screwed together to form a concave groove 14.

Then, by fitting both ends of the air filter 10 into this groove 14 and installing the air filter 10 on the back surface of the suction grill 5, the filter guide 20 can be installed in an inclined state inside the indoor unit main body A. Since the guide substrate 22 is not formed in the part adjacent to the lower part 3a of the container 3,
It becomes possible to install the suction grill 5 very close to the lower part of the evaporator 3, and the depth of the indoor unit main body A can be reduced.

As described above, in this invention, the air filter 10 is attached to the back surface of the suction grill 5 located in front of the evaporator 3 installed in an inclined state in the main body A of the air conditioner. Since the height of the portion of the filter guide 20 provided in the vertical direction that is close to the evaporator 3 is lowered, the suction grill 5 can be placed close to the evaporator, and the indoor unit main body A, for example, separate air It can contribute to making the wall-mounted indoor unit of the harmonizer thinner.
