Problems solved by technology

[0008] In the case of the above two examples, the filter sometimes does not press the lever of the limit switch, so there is a possibility that the filter cannot be detected even if the filter is in the normal home position
In addition, when the filter is warped or twisted in the installed state of the filter, it will detract from the appearance

Embodiment Construction

[0082] figure 1 , figure 2 The indoor unit of the air conditioner of this embodiment is shown. The indoor unit has a heat exchanger 1 and an indoor fan 2 , and the heat exchanger 1 and the indoor fan 2 are installed in a cabinet 3 . A curved surface is formed from the front to the bottom of the cabinet 3 . A suction port 4 is formed on the upper surface of the housing 3, and an air outlet 5 is formed on the curved surface.

[0083] An air duct 6 is formed inside the cabinet 3 from the suction port 4 to the air outlet 5 , and the heat exchanger 1 and the indoor fan 2 are arranged in the air duct 6 . A filter 7 is disposed between the suction port 4 and the heat exchanger 1 (refer to Figure 5 , Figure 7 ), to remove dust from the indoor air sucked in from the suction port 4. Filter 7 is left and right two. The indoor unit is provided with a filter cleaning device which cleans the filter 7 while moving it.

[0084] On the curved surface of the cabinet 3, a panel 10 (bl...

Abstract

Provided are a filter holding device for maintaining a normal filter installation state, and increasing the position detection precision of a limit switch, a filter cleaning device and an air conditioner. A frame is provided with a guide path through which a filter passes, a limit switch for detecting the presence or absence of the filter, a stopper wall that is formed on the end of the guide path and that restricts the movement of the filter, and an inclined wall that is inclined so as to prevent the filter from floating and to lead the filter to the stopper wall side. The inclined wall is formed across the whole area in the width direction of the guide path, and prevents the filter from floating even if the filter were to bend in the width direction of the guide path due to oscillation or operation of the limit switch.

Description

technical field [0001] The present invention relates to a filter holding device for holding a filter attached to an air inlet of an air conditioner or the like. Background technique [0002] A filter is attached to the suction port of the indoor unit of the air conditioner, and dust is removed from the sucked air by the filter. Recently, an air conditioner equipped with a filter cleaning device that cleans the filter while moving it has been proposed. The filter cleaning device has a filter holding device that holds the filter movably. The filter holding device has a frame provided on the cabinet, and a guide passage through which the detachable filter passes is formed on the frame. The filter is held in the housing by means of the guide channel. [0003] For example, in the filter cleaning device described in Patent Document 1, the filter is moved from a position corresponding to the suction port by a toothed belt. Use the brush to scrape the dust from the filter during...
