The orifice 195 which consists of the 2nd body 194 which forms, and guides the suction to the cleaning fan 192 which is a turbo fan to the body which faces the suction surface of the cleaning fan 182 among the 1st and 1st body is It is formed integrally.

The cleaning fan housings 193 and 194 are coupled to the upper side of the cyclone body 182 in the direction in which the orifice 195 communicates with the air outlet 184 of the cyclone body 182.

The cleaning fan housings 193 and 194 have openings 196 through which air is discharged so as to increase the heat radiation performance of the fan motor 52 toward the fan motor 52.

The dust collecting container 200 is a kind of foreign matter collector in which foreign matter discharged from the cyclone body 182 is contained, and is detached from the cyclone body 182 to communicate with the foreign matter outlet 185.

The dust collecting container 200 includes a box body 201 having one surface opened and a cover 202 coupled to the box body 201 to block the open surface of the box body 201.

The dust collecting container 200 is formed with a foreign substance suction unit 203 through which the foreign substance discharged from the cyclone body 182, in particular, the foreign substance discharge port 185 is sucked.

Dust collector 200 is a structure in which foreign matter is accumulated in the lower portion, the foreign matter suction unit 203 is formed in the upper portion of the upper and lower sides of the dust collector 200.

As for the dust collecting container 200, the upper surface of the box body 201 is opened, and the foreign matter suction unit 203 is formed in the box body 201, and the lid 202 covers the upper surface of the box body 201. Explain.

 In the dust collecting container 200, the foreign matter suction unit 203 is formed in the rear portion in a duct shape and is in close contact with the cyclone body 182, especially the gasket 189.

Dust collecting container 200 has a handle 204 is formed to protrude forward to facilitate the user to grab the dust collecting container 200 in the front portion.

Referring to the operation of the present invention configured as described above are as follows.

First, the main PCB 72 is a filter cleaning command is input through a control panel installed in the wall-mounted air conditioner or a remote controller for remotely operating the wall-mounted air conditioner, or the operation condition of the wall-mounted air conditioner is a filter cleaning condition. The filter cleaning signal is periodically output to the cleaning PCB 74.

The cleaning PCB 74 drives the nozzle movement motor 121 when the filter cleaning signal is input, and outputs a control signal for driving the cleaning fan motor 191, and the nozzle movement motor 121 and the cleaning fan motor ( 191 is driven.

When the nozzle movement motor 121 is driven, the driving gear 122 is rotated, the driven gears 125 and 126 are moved along the fixed gear 124 while being rotated by the drive gear 123, and the suction nozzle 110. ) Is moved along the filter 80 in the direction parallel to the longitudinal direction of the fixed gear 124 is moved from one end of the left and right of the filter frame 90 to the other end, the foreign matter in the filter 80 is brush ( 113 is separated from the filter 80.

When the suction nozzle 110 is moved from one end of the left and right of the filter frame 90 to the other end, the nozzle movement motor 121 is driven back so that the rotational direction of the rotating shaft is rotated in the opposite direction, and the suction nozzle 110 ) Is moved from the other end of the left and right of the filter frame 90 to one end.

On the other hand, with the movement of the suction nozzle 110 and the separation of foreign matters accordingly, the cleaning fan 192 is rotated by the driving of the cleaning fan motor 191, the inside of the cyclone body 192, A suction force by the cleaning fan 192 is applied to the inside of the connection hose 170, the inside of the suction duct 135, and the suction nozzle 110.

When the suction force is applied as described above, the foreign matter separated from the filter 80 passes through the suction nozzle 110, the suction duct 135, and the connection hose 170 together with air, and the suction port of the cyclone body 192 ( 183 is introduced into the inner wall surface of the cylindrical portion 186 of the cyclone body 192 and flows along the inner wall surface, and by the cyclone principle while rotating the inner wall surface of the cylindrical portion 186 of the cyclone body 192. Are centrifuged.

The air separated from the foreign matter is moved to the central space of the cylindrical portion 186 of the cyclone body 192 and passes through the air outlet 184 to be sucked into the fan housings 193 and 194 of the intake and exhaust vent 190. It is blown to the periphery of the front part 13, especially the fan motor 52, through the discharge part 196 of the fan housings 193 and 194.

On the other hand, the foreign matter separated from the air is dropped to the lower side of the cyclone body 192 is discharged to the dust collecting container 200 through the foreign matter discharge port 185, the foreign matter is contained in the dust collecting container 200.

 On the other hand, as the cleaning of the filter is performed, foreign matter gradually accumulates inside the dust collecting container 200, and when the user lifts the front panel 26 and grabs the handle 204 and pulls it to the front, the dust collecting container 200. ) Is separated while the foreign matter suction unit 203 is separated from the cyclone body 182 is drawn out to the front through the dust collecting container entrance (24).

Thereafter, the cover 202 is removed from the box body 201 to remove or shake off the foreign matter inside the box body 201 to empty the inside thereof, and then cover the top surface of the box body 201 with the cover 202. The cover 202 and the box body 201 are combined.

Then, the combined dust collector 200 is located in front of the dust collector doorway 24 of the front frame 20, and then inserted into the dust collector doorway 24, the dust collector 200 is moved to the rear to the main body Deeply inserted into the inside of (2), the foreign matter suction portion 203 of the dust collecting container 200 is in close contact with the cyclone body 182.

Finally, when the front panel 26 is rotated side by side with the front surface of the front frame 20, the front panel 26 covers the front of the front opening 5 and the front of the dust collecting container entrance 24, The cleaning operation of 200 is completed.

The present invention, the foreign matter of the filter is sucked into the centrifuge through the suction guide mechanism with the air, and the sucked air and foreign matter is separated by the cyclone principle inside the cylindrical portion of the centrifuge, so that the air and foreign matter to separate The structure is simple because no filtering member such as a net is required, and since the inside of the centrifuge does not interfere with the flow of air and foreign substances, it can be used in a wall-mounted air conditioner, which improves the cleaning ability of the filter.
