Problems solved by technology

However, if the switch panel is opened in the same way in different operation modes, it may not be possible to perform appropriate operation in each operation mode.
Using the above example to illustrate, since the required suction volume is different between full power operation and normal operation, when the switch panel is opened in the same way in ful

Embodiment approach

[0104] (1)

[0105] 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.

[0106] (2)

[0107] 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, capable of achieving an appropriate air suction amount according to operation. An indoor unit (1) of an air conditioner has an indoor unit casing (2) where a first suction opening (21) is provided, a frontal panel (6), a movement mechanism, and a control section. The frontal panel (6) moves so as to depart from the indoor unit casing (2) to open the first suction opening (21) and moves so as to approach the indoor unit casing (2) to close the first suction opening (21). The movement mechanism moves the frontal panel (6) so that the first suction opening (21) is opened at a desired degree of opening. The control section controls the movement mechanism. Further, the movement mechanism can change the degree of opening of the first suction opening (21) to a desired degree.

Description

technical field [0001] The invention relates to an indoor unit of an air conditioner. Background technique [0002] Some indoor units of air conditioners have an opening and closing panel covering a suction port provided in a casing. When the indoor unit of the air conditioner is stopped, the open-close panel can cover the suction port to hide the suction port from the outside, thereby improving the appearance of the indoor unit of the air conditioner. In addition, when the indoor unit of the air conditioner is in operation, the intake of air is ensured by moving the opening and closing panel to open the suction port. (Refer to Patent Document 1). Accordingly, both the appearance and the air blowing performance can be achieved at the same time. [0003] Patent Document 1: Japanese Patent Laid-Open No. 7-98129 (FIG. 1) [0004] However, in the air conditioner as described above, the opening-closing panel only opens the suction port with a single opening degree, so it is d...
