Hereinafter, the left filter cleaning unit (hereinafter, abbreviated as "filter cleaning unit") for cleaning the left suction filter 40 will be described in more detail. The filter cleaning unit, the power transmission unit for transmitting power to the left suction filter 40 (hereinafter, abbreviated as "suction filter 40") to rotate the suction filter 40, and the power transmission A foreign matter separation unit 60 disposed on one side of the suction filter 40 rotated by a unit to separate the foreign matter filtered by the suction filter 40, and the foreign matter separation unit 60 communicates with the foreign matter separation unit 60 to separate the foreign matter. It includes a suction unit 70 for sucking the foreign matter separated from the suction filter 40 by the unit 60 to discharge to the outside.

In general, there may be two ways to clean the suction filter 40. One is to remove the foreign substances caught by the suction filter 40 while moving the filter cleaning unit along the suction filter 40 while fixing the suction filter 40 when cleaning the filter using the filter cleaning unit. The other method is to remove the foreign substances filtered by the suction filter 40 while moving the suction filter 40 while fixing the filter cleaning unit. In one embodiment of the present invention, the latter approach is taken.

In the case of adopting the latter cleaning method, the suction filter 40 is disposed at the left air intake port (hereinafter, abbreviated as "air intake port") so that the air sucked through the air intake port is removed from the intake filter ( It is to be intimately coupled with its surrounding configuration so as to be rotatable and movable so that foreign matter in the air can be sucked into the main body 3 through only 40).

In more detail, the suction filter 40 is disposed to be rotatably movable on a pair of filter panels 45 which are disposed vertically long on the side of the air suction port and spaced apart from each other by a predetermined interval. Except for the space between the pair of filter panels 45, the outside of the pair of filter panels 45 is in close contact with the left support panel (hereinafter, abbreviated as "support panel") so that air does not seep through.

The air inlet is formed.

3 is a partial perspective view illustrating a filter cleaning unit for cleaning the suction filter 40 illustrated in FIG. 2, and FIG. 4 is a cross-sectional view taken along the line A-A of FIG. 3. 3 and 4, rubber belts 55 are disposed at both ends of the suction filter 40 in the width direction so as to be respectively wound at both ends of the transfer pulley 50. One surface of the rubber belt 55 in contact with the outer circumferential surface of the conveying pulley 50 is formed with a gear tooth-shaped gear portion to increase the friction force with the conveying pulley 50. Hereinafter, the gear part formed on one surface of the rubber belt 55 is referred to as "first gear part 56".

On the other hand, the gear portion (not shown) of the shape that meshes with the first gear portion 56 is formed on the outer peripheral surface of the both ends of the transfer pulley 50 that the first gear portion 56 is in contact. Hereinafter, the gear parts formed on the outer circumferential surfaces of both ends of the transfer pulley 50 will be referred to as "second gear parts".

In the present invention, the transfer pulley 50 is rotated when power is transmitted to the transfer pulley 50 in any path, the transfer pulley (a) to the suction filter 40 wound on the outer peripheral surface of the transfer pulley 50 As one power transmission means for smoothly transmitting the rotational force of 50), the first gear portion 56 and the second gear portion are engaged with each other as described above. However, the embodiment of the present invention is not necessarily limited thereto, and a power transmission method using a simple belt in which gear teeth are not formed according to the degree of friction between the rubber belt 55 and the transfer pulley 50 may also be adopted. Of course it is.

At least one side of the pair of transfer pulleys 50 is disposed foreign matter separation unit. The foreign matter separation unit 60, which is disposed outside the suction filter 40 serves to separate the foreign matter filtered by the suction filter 40. The foreign matter separation unit 60, the dust chamber 61 disposed on one side of the transfer pulley 50 to surround a portion of the outer peripheral surface of the transfer pulley 50, and rotatably inside the dust chamber 61 And an agitator 65 disposed to contact the filter 40 to be moved and to separate foreign substances filtered by the filter 40.

2 and 4, the air conditioner 1 further includes a suction unit 70 that communicates with the foreign matter separating unit 60 and provides a suction force to the foreign matter separating unit 60. The suction unit 70 serves to suction the foreign matter separated from the suction filter 40 by the foreign substance separating unit 60 by providing a suction force to the foreign substance separating unit 60 to discharge to the outside. The suction unit 70 is configured on the same principle as a kind of vacuum cleaner. More specifically, as can be seen with reference to Figure 4, the dust chamber 61 of the foreign matter separation unit 60 is open at both sides. One side of both sides of the open dust chamber 61 is disposed close to one side of the outer circumferential surface of the transfer pulley 50 in which the suction filter 40 is disposed. In addition, the other side of the open dust chamber 61 is in communication with the suction unit 70 and the connection hose 75. Here, when the suction unit 70 provides a suction force, the inside of the dust chamber 61 is temporarily out of the air pressure is lowered, the one side of the dust chamber 61 and the suction filter 40 Air is introduced to fill the space between the dust chamber 61 into the space therebetween (see the arrow showing the flow of air in Figure 4). During this process, a predetermined air flow is generated from the open side of the dust chamber 61 to the other side in the dust chamber 61, and foreign matters separated into the dust chamber 61 along the air flow. It is discharged to the outside. However, in order for the foreign matter separated in the dust chamber 61 to be effectively sucked by the suction unit 70, an appropriate suction force should be formed in the dust chamber 61. For this purpose, the separation distance of the space between the open side of the dust chamber 61 and the suction filter 40, which is a portion where air is introduced into the dust chamber 61, is very important. In the exemplary embodiment of the present invention, the close contact member 52 may be fitted to the outer periphery of the transfer pulley 50 so as to closely contact the suction filter 40 toward the dust chamber 61 so that the space is not spaced more than necessary. have. At least one of the pair of transfer pulleys 50 is connected to the power transmission unit. The power transmission unit is a mechanical mechanism for transmitting power to the suction filter 40 to rotate the suction filter 40. The power transmission unit, a drive motor 53 for providing a rotational force to any one of the transfer pulley 50 of the pair of transfer pulleys 50, and at least one of the pair of transfer pulleys 50 transfer The agitator 65 is connected to the rotation shaft of the pulley 50 and receives a rotational force from the first pinion gear 54 and the first pinion gear 54 which are rotated in conjunction with the transfer pulley 50. And second pinion gear 68 connected to either end of the agitator 65 to rotate.

Here, the drive motor 53 and the first pinion gear 54 may be connected to each of the transfer pulley 50 one by one, in the embodiment of the present invention to increase the efficiency of power transmission the drive motor ( 53) and the first pinion gear 54 are connected to the rotation shaft of the transfer pulley 50 corresponding to both ends of one transfer pulley 50, respectively. In addition, it is preferable that the driving motor 53 and the first pinion gear 54 are connected to the transfer pulley 50 side of the pair of transfer pulleys 50 in which the foreign matter separation unit 60 is disposed. Do.

As such, when the first pinion gear 54 is rotated in conjunction with the rotation of the driving motor 53, the second pinion gear 68 receives the rotational force from the first pinion gear 54 and the agitator. 65 is rotated inside the dust chamber 61. The agitator 65 is disposed inside the dust chamber 61 to be in contact with the outer surface of the suction filter 40. The agitator 65 is rotated to catch the outer surface of the suction filter 40. Will separate the foreign matter.

Here, when the first pinion gear 54 and the second pinion gear 68 are directly engaged, the rotation direction of the agitator 65 and the rotation direction of the suction filter 40 are different from each other. However, when the rotation direction of the agitator 65 and the rotation direction of the suction filter 40 are different, there is a problem in that the friction force between the agitator 65 and the suction filter 40 is reduced. As a means to compensate for this, in one embodiment of the present invention, disposed between the first pinion gear 54 and the second pinion gear 68, the first pinion gear 54 and the second The pinion gear 68 further includes a connecting pinion gear 80 that is engaged with the pinion gear 68 and makes the rotation direction of the transfer pulley 50 and the agitator 65 the same. The connecting pinion gear 80 is engaged with the first pinion gear 54 and the second pinion gear 68 at the same time and transmits the rotational force of the first pinion gear 54 to the second pinion gear 68. It delivers, but serves to make the direction of rotation equal to each other. When the first and second pinion gears 54 and the second pinion gear 68 have the same rotation direction, the friction force between the agitator 65 and the suction filter 40 is increased, so that the suction filter 40 is increased. The foreign matter that is filtered out has the advantage of being more easily separated.

Referring to the operation of the embodiment of the air conditioner 1 according to the present invention configured as described above are as follows.

First, when the user operates the filter cleaning unit using a remote control key or the like, the driving motor 53 rotates to rotate one of the transfer pulleys 50 of the pair of transfer pulleys 50.

When the transfer pulley 50 is rotated, the suction filter 40 wound around the outer periphery of the transfer pulley 50 starts rotational movement, and the first pinion is connected to the rotation axis of the transfer pulley 50. The gear 54 is rotated in conjunction with each other, and the rotational force transmitted to the first pinion gear 54 is transmitted to the agitator 65 via the connecting pinion gear and the second pinion gear 68 again. The data 65 is rotated.

At this time, the agitator 65 is the same as the rotation direction of the first pinion gear 54, that is, the suction filter 40 by the connecting pinion gear, so that the agitator 65 and the suction filter 40 The contact portion of the frictional force is increased, and thus, foreign substances filtered by the suction filter 40 can be more easily separated.

On the other hand, when the drive motor 53 is operated, the suction unit 70 which is in communication with the other open side of the dust chamber 61 is operated at the same time, when the suction unit 70 is operated the foreign matter separation unit The foreign matter separated from the suction filter 40 by 60 is discharged to the outside by the suction force of the suction unit 70. At this time, an appropriate suction force is formed by a space formed between the opened one side of the dust chamber 61 and the suction filter 40, that is, the space formed by the contact member 52, thereby cleaning the filter 40. This provides the advantage of improving the cleaning performance of the unit. In addition, since the rotational movement direction of the suction filter 40 and the rotational movement direction of the agitator 65 are the same by the connecting pinion gear 80, foreign matters filtered by the suction filter 40 are easily separated. There is this.

In the above, a preferred embodiment of the air conditioner according to the present invention has been described in detail with reference to the accompanying drawings. However, the embodiments of the present invention are not necessarily limited to those described above, and various modifications or other embodiments falling within the scope equivalent to the present invention can be implemented by those skilled in the art.
