Problems solved by technology

However, in the air conditioner as described above, since the front panel moves forward with the same opening degree regardless of the operation mode, the intake amount of air may be excessive or insufficient.
To explain the above example, in full power operation more suction volume is required than in normal operation, so if the switch panel is opened in the same way in full power operation and normal operation, the suction volume in full power operation may be insufficient. thus not being able to adequately ensure the capacity

Embodiment approach

[0096] (1)

[0097] In the sleep operation of the above-mentioned embodiment, the control unit 8 may control the fan motor 4 so that the output of the blower fan 3 is the first air volume, and control the panel drive motor 73 so that The first suction port 21 opens with the second opening degree. In the case of this control, the air volume of the blower fan 3 is the same as the first air volume in the normal cooling and heating operation, but by opening the first suction port 21 more, the frictional wind noise of the sucked air can be reduced, reducing the Running sound.

[0098] (2)

[0099] In the above-mentioned embodiment, the length of the lower end of the front panel 6 is relatively short for smooth opening and closing operation, and the front panel 6 does not cover the vicinity of the lower end of the horizontal flap 5 . However, the front panel 6 may cover the entire horizontal baffle 5 from the viewpoint of improving appearance.

Abstract

An indoor unit of an air conditioner that can suppress the occurrence of excessive or insufficient air suction amounts is provided. An indoor unit (1) of the air conditioner is provided with an indoor unit casing (2), a front panel (6), and a moving mechanism. A first suction port (21) is provided to the front surface of the indoor unit casing (2). The front panel (6) is provided to the front surface of the indoor unit casing (2), and opens and closes the first suction port (21). The moving mechanism moves the front panel (6) to: a closed state, wherein the front panel (6) closes the first suction port (21); a first open state, wherein the front panel (6) moves frontward from the closed state and opens the first suction port (21); and a second open state, wherein the front panel (6) moves further frontward from the first state and more widely opens the first suction port (21).

Description

[0001] This application is a divisional application of a Chinese invention patent application with an application date of July 13, 2005, an invention title of "indoor unit of an air conditioner" and an application number of 200580023379.7 (PCT / JP2005 / 012914). technical field [0002] The invention relates to an indoor unit of an air conditioner. Background technique [0003] Some indoor units of air conditioners have a front panel that opens and closes a suction port provided on the front surface of the casing. When the indoor unit of the air conditioner is not in operation, the front panel can cover the suction port to hide the suction port from the outside, thereby improving appearance. In addition, when the indoor unit of the air conditioner is in operation, the front panel rotates and moves with the lower end as a fulcrum to tilt forward, thereby opening the suction port to ensure air intake. (Refer to Patent Document 1). Accordingly, both the appearance and the air bl...
