Abstract

PURPOSE: To enable removing or mounting of an air filter easily and moreover, without hazard by pivoting one side of both left and right sides of a suction grill on one side of the main body being rotatable about a vertical shaft to allow opening or closing of the suction grill horizontally. CONSTITUTION: At least one side of both left and right sides of a suction grill 20 is pivoted on one side of the main body 19 being rotatable about a shaft substantially vertical to allow opening or closing of the suction grill 20 horizontally. Opening of the suction grill 20 horizontally enables taking out or mounting of an air filter 9 easily and moreover, without hazard. This facilitates operation, inspection and repairing of devices in the main body 19 and also allows opening of the suction grill 20 even when an obstacle exists at an upper part of the main body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-mounted air conditioner.

[0002]

2. Description of the Related Art One example of a conventional wall-mounted air conditioner is shown in FIG. Juan casing 1 and front panel 2
The heat exchanger 3 is arranged inside the main body 19 consisting of so as to face the suction grille 10, and the flow-through fan 4 is arranged on the downstream side of the heat exchanger 3. A drain pan 8 is arranged below the heat exchanger 3. Horizontal flaps 6a, 6b and a louver 7 are provided at an air outlet 5 formed in a lower portion of the front panel 2.

During operation of the air conditioner, the once-through fan 4 rotates, and the refrigerant from the outdoor unit (not shown) circulates in the heat exchanger 3. Then, the indoor air is sucked from the suction grill 10 to the main body.
When it is sucked into the filter 19 and passes through the filter 9, the dust contained therein is removed. Then, in the process of passing through the heat exchanger 3, it is cooled or heated by exchanging heat with the refrigerant, then sucked into the flow-through fan 4 and urged, and then blown out by the louver 7 and the horizontal flaps 6a and 6b. It is regulated and blown out into the room from the outlet 5.

[0004]

In the conventional wall-mounted air conditioner, since the upper portion of the suction grill 10 is rotatably supported on the upper front portion of the main body 19 about the substantially horizontal shaft 12. As shown in FIG. 4, the air filter 9 must be taken out or attached with the suction grille 10 being lifted by hand, which may be dangerous. Further, if there is an obstacle above the wall-mounted air conditioner, the suction grille 10 may not be sufficiently opened.

[0005]

The present invention has been invented to solve the above-mentioned problems, and the gist of the invention is that it is sucked through a suction grill provided on the front surface of the main body so as to be openable and closable. In a wall-mounted air conditioner in which indoor air flows through an air filter, a heat exchanger, and a fan in this order, at least one of the left and right sides of the suction grill is substantially perpendicular to one side of the main body. A wall-mounted air conditioner characterized in that the suction grill can be horizontally opened and closed by being rotatably supported around various axes.

The left and right sides of the suction grill can be pivotally supported on both sides of the main body to horizontally open and close the suction grill from the center to the left and right sides.

[0007]

In the present invention, if one side of the suction grill is pivotally supported on one side of the main body, the suction grill can be opened and closed horizontally about a vertical axis.

If the left and right sides of the suction grill are pivotally supported on both sides of the main body, the suction grill can be opened and closed horizontally from the center to the left and right sides.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A first embodiment of the invention is shown in FIG. The suction grille 20 has its left side rotatably supported on the left side of the front surface of the main body 19 about an axis substantially vertical, and can be opened and closed horizontally. The other structure is the same as that of the conventional one shown in FIG.

However, if the suction grill 20 is opened horizontally, this state is maintained without holding it by hand, so that the air filter 9 can be taken out and attached easily and without danger. Although not shown, it goes without saying that the right side of the suction grill 20 can be pivotally supported on the right side of the main body 19.

A second embodiment of the invention is shown in FIG. In this second embodiment, the suction grille is divided into left and right, and the left suction grille 21A is pivotally supported on its left side about an axis substantially perpendicular to the front left side of the body 19 and on the right side. The suction grill 21B is pivotally supported on the right side thereof on an axis substantially vertical to the front right side of the main body 19.

However, in the second embodiment,
As shown, the suction grilles 21A and 21B are horizontally opened from the center to the left and right sides, and the air filter 9 can be taken out or attached in this state.

[0013]

According to the present invention, at least one of the left and right sides of the suction grill is rotatably supported about an axis substantially perpendicular to one side of the main body, so that the suction grill can be opened manually. It is maintained in this state without holding it. Therefore, the air filter can be easily taken out or attached without any danger, and the operation, inspection, and repair of the equipment in the main body are facilitated. Then, even when there is an obstacle on the upper part of the main body, the suction grill can be opened.

If both the left and right sides of the suction grille are pivotally supported on both sides of the main body, the suction grille can be opened and closed horizontally from the center to the left and right sides, so that the same effect as described above can be obtained and the horizontal width of the suction grille is short. Therefore, the space for opening and closing can be reduced.
