DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to a structure in which a curved portion of a prefilter is pressed backward to prevent slack.

[0002]

2. Description of the Related Art A conventional air conditioner is, for example, shown in FIG.
As shown in FIG. 2 to FIG. 2 (C), a suction port 1 is provided on an upper front surface and an upper surface of the main body, and a blowout port 2 is provided on a lower front surface. A suction grill 3 having a plurality of vertical bars connecting the horizontal bars is detachably provided, and an air passage connecting the suction port 1 and the air outlet 2 is provided in an air passage.
Flexible grid-like frame 4a and mesh-like filter 4b
And a pre-filter 4 mounted in a curved shape along a filter guide 5 provided on both inner walls of the main body, a heat exchanger 6, and a blower fan 7.

However, since the pre-filter 4 is mounted in a curved shape along the filter guide 5, as shown in a section a of FIG. 2A and FIG.
There is a problem that a gap is formed between the pre-filter 4 and the main body, and dust enters along with the suction air from the location.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, in the present invention, an air conditioner in which a curved portion of a pre-filter is pressed rearward to suppress slackening so that no gap is formed between the pre-filter and a main body. The purpose is to provide a machine.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a main body having a suction port at least at an upper portion of a front surface thereof, an air outlet at a lower portion of the front surface thereof, and a plurality of parallel crosspieces provided at the suction port. And a plurality of vertical bars connecting the plurality of horizontal bars are detachably provided, and a flexible grid-shaped frame portion is provided in an air passage connecting the suction port and the air outlet. And a mesh-shaped filter portion, a pre-filter mounted in a curved shape along a filter guide provided on both inner walls of the main body, a heat exchanger, and an air conditioner including a blower fan. The vertical rib of the suction grill has a configuration in which a pressing rib for pressing the curved portion of the pre-filter backward to prevent slack is protruded.

[0006] The pressing rib is formed such that the thickness of the base end is substantially the same as that of the vertical bar of the suction grille, and the distal end is thin.

[0007] Further, a plurality of the pressing ribs are provided so as to protrude.

[0008] Further, the pressing rib is configured to protrude so as to face a part of the lattice of the frame portion.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as examples. 1A and 1B are explanatory views of an air conditioner according to the present invention, in which FIG. 1A is a cross-sectional view showing a state where a suction grill is mounted, FIG. 1B is a cross-sectional view showing a state where a suction grill is mounted, and FIG. It is the perspective view which looked at the grill from the back, and Drawing 2 (A) is a perspective view of the air conditioner by the present invention (and the conventional example).

As shown in the drawing, the air conditioner according to the present invention is provided with a suction port 1 at an upper portion and an upper surface of a main body, and an outlet 2 at a lower portion of the front surface. The inlet 1 is provided with a detachable suction grille 3 having a plurality of parallel bars 3a and a plurality of vertical bars 3b connecting the plurality of bars 3a.

An air passage connecting the suction port 1 and the air outlet 2 comprises a flexible grid-like frame portion 4a and a mesh-like filter portion 4b, which are provided on both inner walls of the main body. A pre-filter 4 mounted in a curved shape along the filter guide 5, a heat exchanger 6, and a blower fan 7 are provided. When the blower fan 7 is activated, the pre-filter 4 is sucked from the suction port 1. The suction air is cleaned through the pre-filter 4, heat-exchanged by the heat exchanger 6, and sent out from the air outlet 2 toward the room to be air-conditioned.

A pressing rib 8 for pressing the curved portion of the pre-filter 4 rearward to prevent slack is provided on the vertical bar 3b of the suction grill 3 so as to face a part of the lattice of the frame portion 4a. It has a configuration with multiple protrusions.

As a result, no gap is formed between the pre-filter 4 and the main body, as in the part a in the above-described prior art described with reference to FIG. 2C, and as shown in FIG. The structure in which the bent portion of the pre-filter 4 is pressed rearward to prevent the pre-filter 4 from being loosened prevents dust from entering the portion together with the suction air.

The pressing rib 8 is formed to have the same thickness at the base end as the vertical bar 3b of the suction grille 3 and to have a thin end at the front end, so that it has appropriate strength. At the same time, it is possible to easily and integrally mold the suction grill with synthetic resin in a state where a draft angle is provided at the time of molding.

[0015]

As described above, according to the present invention,
An air conditioner is provided in which the bent portion of the pre-filter is pressed backward to suppress the slack, and no gap is formed between the pre-filter and the main body.
