Blowing fan 5 for blowing indoor air and blowing air heat-exchanged in heat exchanger 6 into the room is installed, and blowing fan 5 is driven by fan motor 8. do. Air is sucked in by the operation of the blower fan 5 from the inlet port 2, and dust floating in the air is removed by the air filter 4 provided between the inlet port 2 and the heat exchanger 6.

Moreover, the dust removal means 111 is provided in the upper part of the ejection opening 3, The dust removal means 111 is a dust suction part 113 formed in strip shape over the whole width of the air filter 4, and And a suction fan portion 114 disposed in the side space of the main body 1, and a suction duct portion 115 connecting the dust suction portion 113 and the suction fan portion 114 to each other.

As shown in FIG. 2, the dust suction part 113 is equipped with the film 118 in which the dust suction opening 117 was formed, and the film drive motor 116 for driving the film 118, The film When the film 118 slides by the rotation of the drive motor 116, the dust suction opening 117 moves in a horizontal direction. The dust suction part 113 is provided with the connector 119 connected to the suction duct part 115.

As shown in FIG. 3, one or several air filter movement gears 12 connected to the air filter movement motor are arrange | positioned behind the air filter 4 (heat exchanger side). When there is one air filter shifting gear 120, the air filter shifting gear 120 is installed at the center of the air filter 4, and when there are two air filter shifting gears 120, the air filter shifting gear 120 Are respectively provided at both ends of the air filter 4, and when there are three air filter moving gears 120, the air filter moving gears 120 are provided at the center and both ends of the air filter 4, respectively. . In either case, a plurality of holes in which the teeth of the gears are fitted in the air filter 4 is provided in one vertical row with respect to one air filter moving gear 120, and the teeth of the air filter moving gear 120 are placed in the holes. By inserting sequentially, the rotational force of the motor for moving the air filter is transmitted.

In addition, when there is one air filter movement gear 120, it is driven by one air filter movement motor, but when there are multiple air filter movement gears 120, each air filter movement gear 120 is used for independent air filter movement. You may drive with a motor, and you may drive with one air filter movement motor by connecting several air filter movement gear 120 with a coupling shaft.

The function of the dust removal means 111 of the said structure is demonstrated below.

First, the dust attached to the lowermost part of the air filter 4 is slid by the film 118 by the rotation of the film driving motor 116, and the dust suction port 117 moves from left to right, Or it is sucked as it moves from right to left, and is carried to the suction fan part 114 through the inside of the dust suction part 113 and the suction duct 115, and is discharged | emitted afterwards.

Subsequently, the air filter shifting gear 120 shown in FIG. 3 rotates by a predetermined rotational speed in a predetermined direction, whereby the air filter 4 moves downward by a length corresponding to the length in the longitudinal direction of the dust suction port 117. Move to the dust suction port 117, and stops once when the part which dust is not attracted to face the dust suction opening 117 part. In this state, the dust suction port 117 again moves to the left and right to suck and discharge dust. Thereafter, by repeating this operation, all the dust on the air filter 4 is sucked out.

In addition, when the dust attached to the air filter 4 is cleaned in this way, the dust suction port 117 is preferably formed long in the longitudinal direction, but the dust suction port 117 is formed long horizontally, so that the air filter ( You may clean 4) as follows.

That is, the position of the dust suction port 117 is fixed, and the air filter 4 is slid by the length corresponding to the length of the longitudinal direction in the up-down direction, so that the predetermined width (dust suction port ( The width corresponding to the width of the width 117] is first cleaned, and then the dust suction port 117 is moved by a length corresponding to the width, and then the air filter 4 is moved in the vertical direction in the vertical direction. It slides by the length corresponding to length, cleans the area | region of the predetermined width | region adjacent to the last cleaned area | region in the air filter 4, and repeats this operation | movement by predetermined number of times, You can clean the whole side of 4).

In addition, the cleaning of the air filter 4 may be performed all over the filter surface continuously at once, for example, one row of cleaning may be performed per day, and the whole filter surface may be cleaned over several days.

Here, a shielding plate 121 through which air does not pass is arranged on the surface side of the dust suction port 117 with the air filter 4 interposed therebetween, and both ends thereof are connected to the main body 1. Attached. By providing the shield plate 121 on the rear side of the air filter 4 as viewed from the dust suction port 117, the gap dimension between the air filter 4 and the dust suction port 117 is stabilized. The amount of air sucked into the dust suction port 117 becomes substantially constant, and the wind speed on the surface of the air filter 4 increases, so that it is possible to easily and reliably suck dust.

In addition, the length of the air filter 4 in the longitudinal direction is set to be substantially equal to or slightly longer than the length of the inlet 2, and the air filter 4 is rotated by the rotation of the air filter shifting gear 120. It slides up and down. Moreover, when it moves to the lowest end of the air filter 4, the lower end part of the air filter 4 extends downward from the main body 1, while when the air filter 4 moves to the top end, the air filter 4 will move to a main body It is a structure accommodated in (1).

In the above-mentioned embodiment, although the film 118 provided in the dust suction part 113 was slid to move the dust suction opening 117, for example, the some dust suction opening provided with the lid | cover was 1 It is also possible to adopt a mechanism in which the positions of the inlet openings are changed by opening the lids sequentially, opening only one inlet at a time, and changing the position of the inlet opening.

According to the present invention, since the dust suction portion does not move, the suction duct portion which connects the dust suction portion and the suction fan portion does not need to be stretched and contracted. Therefore, a large space for accommodating the reduced duct is also unnecessary, so that an air conditioner equipped with a compact air filter cleaning device can be realized.

In addition, since the dust suction port is moved in the first direction and the air filter is moved in the direction orthogonal to the first direction, the movement path of the dust suction port becomes a straight line, and stable operation can be obtained with a simple configuration. Can be.

In addition, since a shielding plate through which air does not pass is provided on the face side of the dust suction port by sandwiching the air filter therebetween, the dust filter can be sucked through the air filter between the dust suction port and the shielding plate. The amount of air to be sucked becomes substantially constant, and the wind speed on the surface of the air filter increases, making it possible to easily and reliably suck dust.

As mentioned above, since the air conditioner which concerns on this invention made the air filter move with respect to the dust suction part, it is not necessary to move the dust suction part itself. Therefore, it is not necessary to stretch the suction duct part connecting the dust suction part and the suction fan part, so that a space for accommodating the reduced duct is unnecessary, and a compact air filter cleaning device can be realized. Such a compact air filter cleaning device can be widely applied not only to the indoor unit of an air conditioner but also to a device equipped with a blower and an air filter.
