[0038] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 and figure 2 It is a front view and a side sectional view which show the air cleaner of 1st Embodiment. In addition, arrow S indicates the flow of air. The air cleaner 1 has a casing, and the casing 2 has an opening of a suction port 3 and blowing ports 4 and 5, and is installed on the floor of a room or the like. The housing 2 has a main body 20 and a cover 21 . The cover part 21 is configured to be detachable on the back side of the main body part 20, and the suction port 3 is opened therein. In the main body part 20, the air outlets 4, 5 are opened in the front upper part and the upper surface, respectively.

[0039] Wind direction plates 14, 15 capable of changing the direction of the wind are respectively provided at the outlets 4, 5. The louver 14 is formed of a flat plate, and is supported so as to be rotatable in the vertical direction by a rotation...

[0144] Next, a second embodiment of the present invention will be described. Figure 11 It is a side view which shows the support member of the cover part of the air cleaner of this embodiment. For the convenience of explanation, for the above Figure 1 to Figure 10 The same parts of the first embodiment shown are given the same reference numerals. In this embodiment, the structure of the support member 49 of the cover part 21 differs from 1st Embodiment. Other parts are the same as the first embodiment.

[0145] The support member 49 on the right side of the supply roller 40 of the cover part 21 (refer to image 3 ) is provided with a resin rotating plate 400 that rotates up and down. The shaft part 401 of the rotating plate 400 is offset from the center of the rotating plate 400 in the front-rear direction and arranged behind. Therefore, if Figure 11 As shown, when the supply roller 40 is not attached to the supporting member 49 , the front end portion of the rotating...

[0149] Next, a third embodiment of the present invention will be described. Figure 13 It is a side view which shows the support member of the cover part of the air cleaner of this embodiment. For the convenience of explanation, for the above Figure 1 to Figure 10 The same parts of the first embodiment shown are given the same reference numerals. In this embodiment, the structure of the support member 49 of the cover part 21 differs from 1st Embodiment. Other parts are the same as the first embodiment.

[0150] The supporting member 49 has a fixed part 49a and a moving part 49b. A spring 49c is provided at a rear end portion of the moving portion 49b, and one end of the spring 49c is attached to the front surface of the cover portion 21 . At this time, in the state where the spring 49c is extended, the front-end|tip part of the moving part 49b is comprised so that it may protrude forward rather than the fixed part 49a. Therefore, if Figure 13 As shown, when the supply ...

Abstract

Provide an air cleaner that can sufficiently clean the filter. An air cleaner (1), comprising a casing (2) with openings for the suction port (3) and the blowing ports (4, 5), an air passage (8) connecting the suction port (3) and the blowing ports (4, 5), The blower (10) arranged in the air passage (8), the pre-filter (6) arranged facing the suction port (3), and the cleaning device (30) for cleaning the pre-filter (6), the cleaning device has: Supply roll (40), wound with a pre-filter (6) in sheet form; Winding roll (50), used to wind the pre-filter (6); Drive motor (100), driving the winding roll (50) Rotate; The force application part (70) exerts force on the rotation shaft of the supply roller (40) in the opposite direction of the winding direction when the winding roller (50) is winding; the brush body (80), on the winding roller (50) ) slides on the pre-filter (6) when rotating; and the rotation amount detection part (110) detects the rotation amount of the drive motor (100); judges the failure of the drive motor (100) according to the detection result of the rotation amount detection part (110). step, the drive motor (100) is reversed when the step is lost.

Description

technical field [0001] The present invention relates to an air cleaner provided with a cleaning device for cleaning a filter. Background technique [0002] Patent Document 1 discloses a conventional air cleaner. This air cleaner has a casing with an opening for an inlet and an outlet. An air passage connecting the suction port and the blowing port is provided in the casing, and a blower is arranged in the air passage. Install a pre-filter (filter) facing the suction port. [0003] In the air cleaner configured as described above, when the operation is started, the air blower is driven, and the air in the room is sucked in from the suction port. The air sucked in from the suction port passes through the pre-filter to capture and absorb dust, and is blown out from the blower port. Therefore, indoor air purification can be performed. [0004] In recent years, the demand for an air cleaner equipped with a cleaning device for cleaning a pre-filter has increased. Patent Docu...
