Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner of a type in which a suction port panel is attached to a front cover of an indoor unit.

[0002]

2. Description of the Related Art Generally, a suction port panel is attached to a front cover so as to be openable and closable by hooking a shaft projecting from the suction port panel to a mounting portion such as a hole provided on a front cover surface of an indoor unit. In some cases, an engaging portion is provided on the back surface of the panel and the engaging portion is hidden inside the indoor unit and is detachably attached.

[0003]

In the conventional air conditioner as described above, the former has a design problem because the mounting portion appears on the surface of the front cover and thus the appearance is poor. Also, if the mounting part is provided on the back of the suction port panel, the mounting part is not visible from the outside, so the design is neat, but the engaging part is hidden when the panel is mounted and cannot be seen. There is a risk of breaking the suction port panel when closing the suction port panel in a state where it is difficult to align and the engagement is incomplete.

[0004]

The present invention focuses on this point and solves the above-mentioned drawbacks. In particular, the structure is attached to the main body base and the front surface of the main body base, and the upper suction port is on the front surface. A housing is composed of a front cover having a blow-out port at the bottom and a suction port panel that is attached to the front of the front cover and forms a front suction port, and the suction port panel is opened and closed at the upper part of the suction port panel. Is provided in a protruding manner, and the suction port panel is detachably attached to the front cover by locking the rotation shaft in a recess provided in a part of the upper suction port of the front cover. .

[0005]

Operation: Explaining how to attach and detach the suction port panel 18,
When the lower end of the panel 18 is pulled forward, the claw 26 can be disengaged from the front drain pan 5 and can be opened forward and upward around the rotating shaft 23, and the protrusion 25 of the holder 24 of the front cover 6 can be rotated by a certain amount of rotation. It holds the open state by being locked to the side portion, and when the panel 18 is further rotated and the entire panel 18 is pushed upward, the rotating shaft 23 is easily disengaged from the concave portion 21, so that it is soiled with dust or the like. The entire panel 18 can be washed with water, resulting in a very hygienic and clean panel 18. In addition, the panel 18 is mounted with the rotary shaft 23 hooked from above into the recess 21 of the upper suction port 16 of the front cover 6 with the rotary shaft 23 as the center.
When 8 is rotated downward and the lower end of the panel 18 is finally pushed in, the claw 26 engages with the front drain pan 5 and the mounting of the panel 18 is completed.
