Abstract

PROBLEM TO BE SOLVED: To provide an indoor unit structure of an air-conditioner to prevent formation of a gap being an air flow passage formed in a contact part between a combination outflow grill-drain pan and a combination inlet grill-front panel. SOLUTION: A tangential fan 107 is operated and air sucked through a combination inlet grill-front panel 102 passes through a heat-exchanger 105 for air-conditioning, and the air-conditioned air is supplied through a space between a combination outlet grill-drain pan 106, positioned below the heat- exchanger 105, and a base 110. In the so formed indoor unit of the air- conditioner, a flexible heat insulation material 115 is located in a compression state at a contact part between the combination outlet grill-drain pan 106 and the combination inlet grill-front panel 102.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit structure of an air conditioner comprising an outdoor unit and an indoor unit.

[0002]

2. Description of the Related Art A conventional air conditioner indoor unit structure will be briefly described with reference to FIGS. 3 and 4. FIG. here,
FIG. 3 is a cross-sectional view showing the indoor unit structure of the air conditioner, and FIG. 4 is an enlarged cross-sectional view of a main part showing details of a contact portion between a blow grill and a drain pan and a suction grill and a front panel in FIG.

The indoor unit 1 includes a suction grill / front panel 2, a casing 4, a heat exchanger 5, a blow grill / drain pan 6, a tangential fan 7, a louver 8, a flap 9, a base 10, and the like. . When the air conditioner is operated for cooling, the indoor unit 1
The tangential fan 7 rotates in the direction a, and the indoor air is cooled through the suction grille / front panel 2 and the heat exchanger 5 and then passes between the blowout grille / drain pan 6 and the base 10. The wind direction is determined by the louver 8 and the flap 9 and the air is blown into the room.

[0004]

During the cooling operation of the indoor unit 1 having the above-described structure, the outlet grill and drain pan 6 is cooled by the drain water dripped from the heat exchanger 5 and the outlet wind, so that it is warm. When it comes into contact with the flow of indoor air (hereinafter, referred to as an intake air flow) 14 (see FIG. 4), when the moisture of the intake air flow 14 touches the outlet grille and drain pan 6, dew is formed. .
For this reason, a hard heat insulating material 15 such as styrene foam is provided on the side (lower surface) of the outlet grill and drain pan 6 on the outlet grill side.
And 16 are adhered, thereby reducing the temperature difference to prevent dew.

However, in the contact portion between the hard heat insulating material 15 and the suction grille / front panel 2, it is difficult to completely adhere them because both are formed of a hard material. Therefore, a gap 18 is generated in the contact portion, and the warm suction air flow 14 continuously passes through the gap 18 due to the suction force of the tangential fan 7, so that a large amount of dew 19 is generated around the gap 18, There was a problem that the dew dripped into the room.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has prevented the formation of a gap that forms a passage for air at a contact portion between a blow grill and a drain pan and a suction grill and a front panel. An indoor unit structure of an air conditioner is provided.

[0007]

The present invention has solved the above-mentioned problems by the present invention. The air conditioner indoor unit structure according to claim 1, wherein the air sucked from the suction grille and the front panel is operated by operating a tangential fan to be air-conditioned through the heat exchanger, and the conditioned air is cooled by the heat exchanger. In the indoor unit structure of the air conditioner in which air is blown out between the base and the outlet grill and drain pan located below the base, the contact portion between the outlet grill and drain pan and the suction grill and front panel has flexibility. The heat insulating material is interposed in a compressed state.

In this case, it is preferable that the flexible heat insulating material is provided on the side of the outlet grill and the drain pan. The flexible heat insulating material provided on the side of the outlet grille and the drain pan may be provided with a protruding portion that is compressed between the suction grille and the front panel in an assembled state. A suitable flexible heat insulating material is foamed ethylene propylene rubber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an indoor unit structure of an air conditioner according to the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a main part showing details of a contact portion between an outlet grill and a drain pan and an inlet grill and a front panel in an indoor unit of an air conditioner, and corresponds to FIG. FIG. 2 shows FIG.
3 is an enlarged view of the portion A of FIG.

The indoor unit 101 includes a suction grill / front panel 102, a casing 104, and a heat exchanger 10.
5, a grill and drain pan 106, a tangential fan 107, a louver 108, a flap 109, a base 110, and the like. The basic configuration is the same as that shown in the prior art. In the present invention, a flexible heat insulating material (hereinafter referred to as a flexible heat insulating material) 115 such as foamed ethylene propylene rubber or the like is used so that no gap is formed at a contact portion between the blow grill and drain pan 106 and the suction grill and front panel 102. It is affixed to the outlet grill and drain pan 106 side. This flexible insulation 115
Is provided with a protruding portion 115a having an L dimension that allows for the amount of compression in the assembled state. Reference numeral 116 in the figure is a hard heat insulating material such as styrene foam.

When the air conditioner is operated for cooling, the tangential fan 107 of the indoor unit 101
The air in the room is sucked from the suction grill and front panel 102 and then cooled through the heat exchanger 105. The conditioned air thus cooled passes between the outlet grill and drain pan 106 and the base 110, and is blown into the room with the air direction determined by the louver 108 and the flap 109.

At this time, the outlet grill and drain pan 10
A flexible insulating material 115 such as foamed ethylene propylene rubber is blown out of the grill / drain pan 10 so that no air gap is formed at the contact portion between the suction grille 6 and the suction grille / front panel 102.
Attached to the 6 side, and the suction grille and front panel 1
Since the protruding portion 115a having the L dimension that allows for the compression is provided on the flexible heat insulating material 115 on the side that comes into contact with the front surface 102, the flexible heat insulating material 115 is flexible at the contact portion between the suction grille and the front panel 102. Thermal insulation 115
Is made of a soft material having flexibility, so that it can be completely adhered. Therefore, no gap is generated in the contact portion,
The suction force of the tangential fan 107 from outside the outlet grille and drain pan 106 can prevent the warm suction airflow from continuously passing. As a result, the flexible heat insulating material 115 and the suction grille / front panel 1
The problem that dew is not generated in the vicinity of the contact portion with the dew 02 and the dew drops from the indoor unit 101 into the room is solved.

[0013]

As described above, according to the indoor unit structure of the air conditioner of the present invention, the flexible heat insulating material is interposed at the contact portion between the outlet grill and the drain pan and the inlet grill and the front panel. It is possible to prevent a gap, which is a passage for a warm suction air flow sucked from the room, from being formed in the contact portion in an assembled state. As a result, the occurrence of dew near the contact portion can be prevented, so that the dew does not drip into the room.
