Problems solved by technology

[0012] Even so, there is still such a problem that the inside of the indoor unit 100 is immersed in dust after a long time, and the dust adheres to the cross-flow fan, etc. When it starts up (when the cross-flow fan starts to rotate), it flies up and is blown into the room

Embodiment Construction

[0019] Embodiments of the present invention will be described below with reference to the drawings. The split-type air conditioner is composed of an outdoor unit installed outdoors, and an indoor unit installed indoors connected to the outdoor unit by refrigerant pipes, and the refrigerant circulates between the outdoor unit and the indoor unit.

[0020] Fig. 1 is a side sectional view showing a so-called wall-mounted indoor unit 10 hung on an indoor wall among the indoor units of the present invention.

[0021] The indoor unit 10 has a horizontally long casing 11 made of plastic or the like, and the casing 11 is provided with an indoor heat exchanger 19, a cross-flow fan 18, and a control unit not shown in the figure.

[0022] A grille 13 forming a front air intake 12 is provided on the front of the casing 11, and an upper air intake 14 is formed thereon.

[0023] An air outlet 15 for blowing conditioned air into the room is formed at the lower end of the casing 11, and a wi...

Abstract

At the time of starting operation of the indoor unit, opening of a flap is decreased to bring about an air short mode where the air supplied from an air outlet is not diffused into a room but sucked, as it is, from a front air inlet and an upper surface air inlet and passed through a dust collection filter thus accelerating settlement of dust adhering to the inside of the indoor unit at the time of starting operation. Dust generated at the time of starting the indoor unit can thereby be prevented from being diffused into the room.

Description

technical field [0001] The present invention relates to an air conditioner in which dust adhering to the interior of the indoor unit does not fly up and be blown indoors when the indoor unit is activated. Background technique [0002] At present, air conditioners are very popular even in ordinary households, and the split type air conditioners in which the indoor unit and the outdoor unit are used separately are dominant. [0003] Fig. 2 is a cross-sectional view suitable for explaining an air conditioner in the prior art. Among such indoor units, a wall-mounted indoor unit 100 is a cross-sectional view of a wall-mounted indoor unit 100 used for hanging on an indoor wall. The wall-mounted indoor unit 100 has plastic The horizontally long housing 101 is formed. [0004] A grille 103 forming a front air intake 102 is installed on the front of the housing 101, and an upper air intake 104 is formed on the top simultaneously. [0005] At the lower end of the casing 101, an air ...
