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 by removing it.

  In the filter device having such a configuration, frequent maintenance is required, and until the maintenance is performed, the air filter is gradually clogged with dust, and as a result, the amount of air 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 that periodically cleans dust adhering to the air filter with a brush in order to reduce the maintenance work of the filter (see, for example, Patent Documents 1 and 2).
JP 2001-99479 A Japanese Patent Laid-Open No. 2005-24135

  However, in the conventional configuration, it is necessary to manually dispose of accumulated dust, and the maintenance labor is not greatly reduced.

  From this point of view, the air filter automatic cleaning device is preferably a cleaning method in which dust attached to the filter is scraped off with a brush and then sucked and cleaned, and the sucked dust is collected in the dust collector or discharged to the outside. .

  The present invention solves the above-mentioned conventional problems, and provides a filter device that greatly reduces the troublesome maintenance of an air conditioner.

In order to solve the conventional problems, the air conditioner of the present invention includes a filter that removes dust in the air and a first removal member, and the first filter from one end to the other end on either side of the filter. A movable dust removing unit that scrapes the dust adhering to the filter by moving the removing member in contact with the filter, and rubbing the first removing member provided on the other end side of the filter. And a fixed dust removing unit having a second removing member for separating the dust scraped by the first removing member from the first removing member.

The fixed dust removing unit further includes a duct that collects the dust that is separated by rubbing the first and second removing members.

Further, the apparatus further includes a suction device that is connected to the duct and sucks the dust through an air flow passage formed by bringing the fixed dust removing unit and the duct into close contact with each other.

  According to this configuration, the dust adhering to the surface of the filter can be automatically removed, sucked by the suction device, and collected in the dust collector or discharged outdoors.

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.

The first invention has a filter that removes dust in the air and a first removal member, and moves the first removal member from one end to the other end of the filter while contacting the filter. By moving the dust attached to the filter to the movable dust removing portion and rubbing with the first removing member provided on the other end side of the filter, the first removing member A fixed dust removing unit having a second removing member for separating the scraped dust from the first removing member.

  According to a second invention, in the first invention, the fixed dust removing unit further includes a duct for collecting the dust that is separated by rubbing the first and second removing members.

  According to a third invention, in the first invention, there is further provided a suction device that is connected to the duct and sucks the dust through an air flow passage formed by closely contacting the fixed dust removing portion and the duct. It is a thing.

According to these configurations, the dust adhering to the surface of the filter, as well as automatically remove, by suction by the suction device, it is possible to discharge the dust collection or outdoors dust collector.

  By doing so, the filter device 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.

  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)
1 is a perspective view of a filter device 1 according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB 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. It is supported by a guide rail 6 installed at the end via a roller 11 as shown in FIG. 2, and is configured to be movable left and right. Here, the movable dust removing unit 8 is driven left and right by the wire 3 and the drive motor 4 provided at the lower part of the filter bowl 7.

The movable dust removing unit 8 includes a removing member 12 as shown in FIGS.
For example, the removal member 12 is preferably a brush such that the tip of the bristle is inclined with respect to the surface of the filter 2 as shown in FIG. As shown in FIG. 1, the fixed dust removing unit 13 is fixed to the filter cloth 7 and includes a removing member 14.

  For example, as shown in FIG. 3, the removal member 14 is preferably a brush like the tip of the bristle that is inclined with respect to the surface of the filter 2 as shown in FIG. 3.

  As shown in FIG. 1, the duct 15 includes a suction port 16 and an air inflow port 17.

The suction device 9 is connected to the duct 15 at the suction port 16 , and is connected to the exhaust duct 10 routed to the outdoors. As shown in FIG. 3, the duct 15 also includes a sealing material 18.

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 removing unit 8 is waiting at the right end of the filter cloth 7.

  When the filter device 1 is actuated, the movable dust removing unit 8 moves to the left while scraping the dust adhering to the air filter 2 by the removing member 12.

  At the place where the removal member 12 of the movable dust removing unit 8 and the removing member 14 of the fixed dust removing unit 13 are in contact, the movable dust removing unit is reciprocated several times to the left and right.

  By doing so, the dust adhering to the removing member 12 of the movable dust removing unit 8 is detached from the removing member 12 of the movable dust removing unit 8 by interaction with the removing member 14 of the fixed dust removing unit 13. It will be.

  When the movable dust removing unit 8 is further advanced leftward, the movable dust removing unit 8 comes into close contact with the sealing material 18 provided in the duct 15.

  By doing so, an air flow passage is formed by the movable dust removing portion 8 and the duct 15. When the suction device 9 is operated in this state, air flows in from the air inlet 17 provided in the duct 15, and the dust in the duct 15 passes through the suction port 16 due to the force of the flowing air, It is sucked into the suction device 9. The sucked dust passes through the exhaust duct 10 and is discharged outside.

  This makes it possible to automatically remove dust adhering to the surface of the filter, reducing the burden of regular maintenance on air conditioner users, and at the same time suppressing the deterioration of performance for long-term operation. The air conditioner which can be provided can be provided.

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

  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.
