Description

  The present invention relates to an air conditioner that automatically cleans an air filter.

  Conventionally, in an air conditioner filter device, an air filter is disposed on the upstream side of a heat exchanger in order to prevent dust from entering the heat exchanger and the air conditioner. The air filter can be attached and detached freely, and it is easy to remove dust attached to the air filter.

  The filter device having such a configuration requires frequent maintenance, and until the maintenance is performed, the air filter is gradually clogged with dust, and as a result, the air volume passing through the heat exchanger is also reduced. It gradually decreases, leading to an increase in power consumption.

  For this reason, an automatic cleaning device has been devised for periodically cleaning the dust attached to the air filter with a movable suction nozzle in order to reduce the maintenance work of the filter.

Here, the suction nozzle has a pulley and moves along a guide rail (see, for example, Patent Document 1).
JP 2005-147546 A

  However, in the conventional configuration, when the suction nozzle is driven in the left-right direction, the suction nozzle itself is slightly tilted around the pulley, so that the suction nozzle is pressed against the filter and frictional force is generated. There is a problem in that the movement of the suction nozzle may increase due to increase.

  An object of the present invention is to solve the above-mentioned conventional problems, and to reliably operate a filter device that greatly reduces the troublesome maintenance of an air conditioner.

  In order to solve the above-described conventional problems, a filter device according to the present invention includes an air filter and a guide rail that collect dust in the air that passes through a heat exchanger on the wind of the heat exchanger. And a dust removing unit that moves along the guide rail and removes dust attached to the air filter, the dust removing unit including two pulleys having a shaft in a horizontal direction, and a vertical direction It is characterized by having two pulleys with shafts.

  According to this configuration, it is possible to prevent the movable dust removing unit itself from being tilted around the pulley during the operation of the movable dust removing unit.

  That is, it is possible to reliably remove dust attached to the surface of the air filter, and the dust can be sucked by the suction device and discharged to the outdoors.

The filter device for an air conditioner of the present invention provides an air conditioner that can reduce the burden of regular maintenance of the user of the air conditioner and at the same time can suppress a decrease in performance for long-term operation. I can do it.

  According to a first aspect of the present invention, there is provided a filter device according to the present invention, comprising: an air filter that collects dust in the air passing through the heat exchanger on the wind of the heat exchanger, and a guide rail; A dust removing unit that moves along the guide rail and removes dust adhering to the air filter is provided, the dust removing unit includes two pulleys having a shaft in the horizontal direction, and has a shaft in the vertical direction. It is characterized by comprising two pulleys.

  According to this configuration, it is possible to prevent the movable dust removing unit itself from being tilted around the pulley during the operation of the movable dust removing unit.

  That is, it is possible to reliably remove dust attached to the surface of the air filter, and the dust can be sucked by the suction device and discharged to the outdoors.

  By doing this. ADVANTAGE OF THE INVENTION The filter apparatus of this invention can provide the air conditioner which can reduce the burden of the regular maintenance of the user of an air conditioner, and can suppress the fall of the performance with respect to a long-term driving | operation at the same time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments.

FIG. 5 is a front view of the air conditioner according to Embodiment 1 of the present invention, and FIG. 4 is a cross section taken along line II in FIG.

  In FIG. 1, the filter cloth 7 includes an air filter 2 that removes dust in the air that passes through the heat exchanger, and a movable dust removing section 8, and the movable dust removing section 8 is located above and below the filter cloth 7. The guide rail 6 installed at the end is supported via a pulley 12 as shown in FIG. 2, and is configured to be movable left and right.

  Here, the movable dust removing unit 8 drives the wire 3 provided in the lower part of the filter cloth 7 to the left and right via the pulley 5 by the drive motor 4.

  The movable dust removing unit 8 faces the filter 2, has an air suction port, and is connected to the inside of the movable dust removing unit 8.

  Furthermore, the movable dust removing unit 8 is connected to the bellows 9, the suction device 10, and the exhaust duct 11 drawn around outdoors.

  In FIG. 3, the movable dust removing unit 8 includes two pulleys 13 having a shaft in the horizontal direction and two pulleys 14 having a shaft in the vertical direction with respect to one guide rail 6.

  About the filter apparatus 1 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the operation of the filter device 1 is stopped, the movable dust container 8 is waiting at the right end of the filter cloth 7.

When the filter device 1 is operated, the suction device 10 is operated, and at the same time, the movable dust removing unit 8 is moved from the left to the right.

  The dust adhering to the filter 2 is sucked from the air suction port, sucked to the suction device 10 through the bellows 9, and further discharged to the outdoors through the exhaust duct 11.

  The movable dust removing unit 8 moves left and right along the guide rail 6, but comes into contact with the two guide rails 6 in the horizontal direction through the pulley 13 and in the vertical direction through the pulley 14. Therefore, the movable dust removing unit 8 is restricted from moving in a direction other than the left-right direction, and it is ensured that the suction nozzle is pressed against the filter and the movement of the suction nozzle is stopped by the frictional force. It becomes possible to prevent.

  As a result, dust adhering to the surface of the filter can be removed automatically and reliably, reducing the burden of regular maintenance on air conditioner users, and at the same time lowering the performance for long-term operation. It is possible to provide an air conditioner capable of suppressing the above.

  In the present embodiment, the movable dust storage unit 8 is moved left and right along the filter cloth 7, but it may be moved up and down along the filter fact 7.

  Further, the number of pulleys may be more than two.

  As described above, the filter device for an air conditioner according to the present invention has a maintainability capable of automatically cleaning dust adhering to the air filter, and collects dust in the air such as an air purifier or a control panel. Applicable to equipment equipped with dust filter.
