BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a filter mounting structure in an air conditioner.

[0002]

2. Description of the Related Art For example, a wall-mounted air conditioner mounts a main body case containing a heat exchanger, a drain pan, a fan, etc. in a mounting frame embedded in a wall surface, and a front edge of the mounting frame. The front grill is attached to the main body case so as to face the suction port. In other words, the front grill is different from that of the wall-mounted air conditioner, is separate from the main body case, is selected as a interior such as a wooden lattice frame in a Japanese room, and is attached to the installation frame from the indoor side. I have. Therefore, unlike the filter of the wall-mounted air conditioner in which the main body case and the front grille are integrated, the filter of the wall-mounted air conditioner cannot be mounted on the front grill side, but is mounted on the main body case side. That is, the above-described filter conventionally inserts an upper edge into a slit provided on an upper edge of a suction port of a main body case, and inserts a lower edge,
It was mounted on a plurality of support pieces fixed at intervals on the lower edge of the suction port.

[0003]

However, in the above-mentioned conventional filter mounting structure, it is necessary to fix a plurality of support pieces one by one to the lower edge of the suction port in order to support the lower edge of the filter. Therefore, there are drawbacks that the number of assembly steps of the air conditioner increases and that a support piece is separately required, so that the number of parts increases and the cost of the product increases. Therefore, an object of the present invention is to provide a filter mounting structure for an air conditioner that can reduce the number of assembly steps and the number of parts by effectively using a drain pan in a main body case.

[0004]

In order to achieve the above object, a filter mounting structure for an air conditioner according to the present invention includes a mounting frame 1 embedded in a wall W as shown in FIG.
An air conditioner in which a main case 2 containing a heat exchanger 7, a drain pan 9 and a fan 10 is attached, and a front grill 4 is attached to a front edge 1a of the installation frame 1 so as to face a suction port 11 of the main case 2. A rib is formed integrally with the front edge of the opening 9a of the drain pan 9, and the lower edge 13a of the filter 13 is directly contacted with the upper surface of the rib 14 to support the lower edge 13a. And

[0005]

The filter 13 has a lower edge 13a supported by a rib 14 provided at the front edge of the opening 9a of the drain pan 9,
The front grille 4 attached to the installation frame 1 is mounted so as to cover the suction port 11 of the main body case 2 and covers the entire front surface of the filter 13. Since the ribs 14 are provided integrally with the drain pan 9, the filter 13
Separate components and their attachment are no longer required to support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. FIG. 1 is a longitudinal sectional view of an embedded type air conditioner employing the filter mounting structure of the present invention in an installed state. This air conditioner has an installation frame 1 embedded in a wall W.
Body case 2 mounted inside the body case 2
And a front grill unit 3 attached to the front edge 1a of the installation frame 1 so as to face the suction port 11. In the main body case 2, an upper suction port 11 is provided.
A heat exchanger 7 having an electrostatic precipitator 8 fixed to the front upper part is obliquely accommodated, and a drain pan 9 for collecting dew condensation water is horizontally provided at a lower end thereof, and a fan is provided at a lower blowing part 12 side. 10
Will be accommodated. On the other hand, the front grill unit 3
The front grille 4 includes a front grille 4 occupying a large part facing the inlet 11 and a lower outlet 5 having vertical and horizontal blades for driving the blown air and a drive motor 6.
The left, right, and upper edges are fixed to the installation frame 1 as described above, and the left, right, and lower edges of the air outlet 5 are attached to the installation frame 1 in a state of being fitted into the blowout portion 12 of the main body case 2. Fixed.

The feature of the present invention is that the drain pan 9 shown in FIG.
A rib 14 for supporting the lower edge 13a of the filter 13 is provided at the front edge of the opening 9a. This rib 14 is
A through rib 14a integrally formed over the entire length of the front edge in the shape of a letter, and several claws 14b provided at its base at intervals in the through direction so as to abut against the lower surface of the lower end of the filter 13. And is disposed along and in contact with the lower edge 11 a of the suction port 11 of the main body case 2. The upper edge 11b of the suction port 11 of the main body case 2 is provided with a slit 2b into which the upper edge 13b of the filter 13 is inserted. Therefore,
The filter 13 inserts the upper end edge 13b into the slit 2b and mounts the lower end edge 13a on the rib 14a through the rib 14a as shown in the figure before mounting the front grill unit 3 on the main body case 2 mounted on the installation frame 1 in the wall surface W. Be attached. Note that the filter 13 has a projection 13c at the center of the lower end edge as a clue for attachment and detachment. The rib 14 and the slit 2b
In between, a long-life filter 15 having a large thickness as shown by a broken line in the figure can be attached.

[0008] According to the filter mounting structure having the above structure,
Since the rib 14 for supporting the lower edge 3a of the filter 3 is provided integrally with the drain pan 9, unlike the conventional example in which a plurality of support pieces are fixed to the lower edge of the suction port at intervals, a separate part is provided. And its installation is not required. Therefore, the number of assembly steps and the number of parts of the main body case 2 can be reduced, and the cost of the main body case 2 can be reduced.
Since the ribs 14 in the above embodiment are L-shaped and pass through, even if dew condensation occurs near the filter 13,
Since the rib 14 functions as a guide for the inflow of dewed water to the drain pan 9, there is an advantage that the dew countermeasure is excellent. Of course, the rib of the present invention is not limited to the L-shaped rib of the above-described embodiment, and may be of any shape as long as it is provided at the front edge of the opening of the drain pan. Further, in the above embodiment, the air conditioner of the wall-embedded type has been described. However, it is needless to say that the filter mounting structure of the present invention can be applied to other air conditioners such as a wall mounted type.

[0009]

[Effects of the Invention] As is clear from the above description, the filter mounting structure of the present invention is installed in an installation frame embedded in a wall surface.
In an air conditioner having a front grille attached to a front edge of the installation frame facing a suction opening of the main body case while attaching a main body case containing a heat exchanger, a drain pan, and a fan, the front of the drain pan opening is provided. A rib is integrally formed on the edge, and the lower edge of the filter is directly abutted on the upper surface of the rib to support the lower edge. This eliminates the need for a separate component for supporting the filter and its attachment. In addition, the number of assembly steps and the number of parts of the main body case can be reduced, and the cost can be reduced.
