Description

  The present invention relates to an air conditioner filter device that automatically cleans an air filter of an air conditioner, and an air conditioner using the same.

  In a conventional general air conditioner, an air filter for preventing dust from entering the inside of the air conditioner main body is provided on the front surface of the heat exchanger, and this air filter removes adhering dust. It can be detachably attached to the air conditioner body so that it can be cleaned by hand. However, such an air filter not only requires frequent maintenance, but until the maintenance is performed, the air filter gradually clogs, and as a result, passes through the heat exchanger. The air volume is reduced, the air conditioning capacity is reduced, and the power consumption is increased.

Therefore, in order to reduce the maintenance work of the air filter, the dust that adheres to the air filter is regularly and automatically cleaned with a brush, and the filter device of the air conditioner that collects the dust in the collection box Has been proposed (see, for example, Patent Document 1).
JP 2001-99479 A

  However, in the configuration of the filter device of the conventional air conditioner described above, after a certain amount of time has passed, the dust collected by the brush and collected in the collection box must be processed, which greatly reduces the maintenance effort. It was not a thing.

  The present invention solves the above-described conventional problems, and an object thereof is to provide an air conditioner filter device and an air conditioner excellent in maintainability.

  In order to solve the conventional problems, an air conditioner filter device of the present invention includes an air filter that collects dust contained in air passing through a heat exchanger, and dust collected by the air filter. A removal member to be removed, a dust storage portion for storing the dust removed by the removal member, a suction device communicating with the dust storage portion, and a driving means for driving the air filter, The adhering dust can be scraped off by the removal member, collected in the dust storage area, sucked by the suction device, and then collected in a separate dust collector or discharged outside, greatly improving maintenance. To do.

  The air conditioner filter device and the air conditioner according to the present invention are capable of automatically cleaning dust adhering to the air filter and are extremely excellent in maintainability.

  According to a first aspect of the present invention, there is provided an air filter for collecting dust contained in air passing through a heat exchanger, a removing member for removing dust collected by the air filter, and dust removed by the removing member. A dust storage unit to be stored, a suction device communicating with the dust storage unit, and a driving means for driving the air filter. The dust adhering to the air filter is scraped off by a removing member to the dust storage unit. While being collected, it can be sucked by a suction device and collected in a separately provided dust collector or discharged outside the room, which greatly improves maintenance.

  In particular, the second invention uses a wire as the driving means of the first invention, and with a simple configuration, the air filter can be moved while being in sliding contact with the removal member, so that the dust removal performance is improved.

  In particular, the third invention uses a timing belt as the driving means of the first invention, and the attached dust can be more reliably scraped off, so that the cleaning property can be improved.

  4th invention is equipped with the filter apparatus of the air conditioner described in any one of Claims 1-3, and this can save the effort which regularly cleans the dust adhering to an air filter Therefore, the maintainability can be improved.

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

(Embodiment 1)
FIG. 1 is a perspective view of a filter device for an air conditioner according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view (cross section AA in FIG. 1) of the filter device for the air conditioner. is there.

  1 and 2, a rotatable winding shaft 3 for winding an air filter 2 and a drive motor are provided below a filter device 1 (hereinafter referred to as “filter device 1”) of an air conditioner according to the present embodiment. 4 and a gear 6a that is attached to the drive motor 4 and drives the wire 5 are provided. At the upper part of the filter device 1, a rotatable support shaft 7 that pulls and supports the air filter 2 and the support shaft 7 rotate. A gear 6b is provided that applies force and is rotationally driven by the wire 5, and has a frame 8 that guides the air filter 2 from the winding shaft 3 to the support shaft 7.

  A plurality of wires 5 and pulleys 9 that can drive the air filter 2 are provided on the side surface of the frame 8, and a dust container 10 is provided at the lower part of the frame 8.

  The dust storage unit 10 communicates with the suction device 11, and the suction device 11 is connected to an exhaust duct 12 that is routed outside the room. An air inlet 13 for taking in outside air is provided at the end of the dust container 10 opposite to the suction device 11. Further, as shown in FIG. 2, a removal member 14 that contacts the surface of the air filter 2 and removes adhering dust is provided inside the dust container 10.

  About the filter apparatus 1 in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
