Description

[Detailed Description of the Invention] The present invention relates to an improvement in the fixing structure of a front grill in an air conditioner.

Conventionally, indoor units of air conditioners have been mostly screwed from the front of the front grill.

In recent years, there has been a trend to make indoor units thinner in order to make greater use of living space, and in order to make them thinner, it is necessary to eliminate wasted space in the indoor unit body.

A problem that has arisen with this is the locking structure of the front grille.

Hereinafter, the present invention will be described with reference to FIGS. 1 to 3 of the accompanying drawings showing one embodiment thereof.

In the figure, reference numeral 1 denotes an indoor unit main body of a separator type air conditioner, which is composed of a front grill 2 and a substrate 3.

The front grille 2 includes a suction section 4 and an outlet section 5 on the windward side of the air passage, and an air filter 6 is attached to the leeward side of the suction section 4.

In addition, the board 3 includes a blower 7, an air guide 8, and an air blower 8 that act as a blower structure. It is composed of a stabilizer 9, and a heat exchanger 10 is provided on the windward side of the blowing structure.

The stabilizer 9 has a structure to stop the front grille 2 and supports and reinforces the water tray 11 made of a heat insulating material such as styrofoam. On the side of the water tray 11 that opposes the screws 12, there is a part of the stabilizer 9. A protection piece 13 formed by cutting and raising is provided.

Further, 14 is a lower water tray for receiving water falling from the water tray 11, and 15 is a protection ring for the screw 12.

Next, a conventional front grille fixing structure will be explained with reference to FIG. 5 of the accompanying drawings.

Conventionally, the front grille has been fixed directly from the front grille 102 to the stabilizer 109 with screws 112.

However, according to this configuration, the tip of the screw 112 and the water tray 1
There is a risk of contact with 11.

In addition, in the case of drops or vibrations that occur during transportation, the water tray 11
There is a risk that the screw 112 may hit the water tray 111 and cause cracks or holes in the water tray 111, resulting in water getting wet.

Furthermore, during repair and inspection at the consumer's home, there is a possibility that long screws may be used by mistake in order to remove the front grille 102, which is extremely dangerous.

On the other hand, if the distance between the screw 112 and the water tray 111 is increased in order to avoid the above-mentioned danger, a reduction in thickness cannot be expected, so there is a drawback that the living space cannot be used effectively.

However, in this embodiment, the protective piece 13 cut and raised from a part of the stabilizer 9 prevents the tip of the screw 12 from hitting the protective piece 13 not only when it falls or vibrates, but also when a long screw is used by mistake. Therefore, the risk of damaging the water tray 11 or causing holes or cracks is eliminated.

Furthermore, since the protective piece 13 also serves as a support for the water tray 11, it serves to position and reinforce the water tray 11, and since the protective piece 13 has a cut-and-raise structure, the material cost can be kept the same as in the past.

In addition to having the above-mentioned advantages, the distance between the screw 12 and the water receiving tray 11 can be shortened, so that it can be made thinner.

In this embodiment, the protective piece 13 is formed by cutting out a part of the stabilizer 9, but as shown in FIG. Similar effects can be obtained even if the configuration is provided in the above, and does not depart from the gist of the present invention.

As is clear from the above embodiments, the front grill fixing structure of the air conditioner according to the present invention has a protective piece on the water tray side opposite to the screws that fix the front grill.
It prevents the water tray from being damaged by the screws due to drops or vibrations that occur during transportation, and supports and reinforces the water tray.Furthermore, there is no need to provide a large gap between the screws and the water tray, allowing air conditioners to be made thinner. It can be measured.

In addition, the fixed piece is a stabilizer that forms a ventilation path, and a protective piece is formed by providing a cut and raised piece on a part of this stabilizer, or a protective piece is formed by pasting a metal piece such as an iron plate on the front wall of the water tray. By doing so, it has various advantages such as being extremely simple in structure and being able to be manufactured at low cost.
