Description

  The present invention relates to an air conditioner equipped with a filter device that automatically cleans a filter.

  In a conventional air conditioner filter device, an air filter is provided on the front surface of the heat exchanger to prevent dust from entering the inside of the air conditioner body. It is configured to be detachable so that it can be cleaned. The filter device with such a configuration not only requires frequent maintenance, but the air filter gradually clogs until maintenance is performed, resulting in a reduction in the amount of air passing through the heat exchanger. As a result, the air conditioning capacity is reduced, leading to an increase in power consumption.

  For this reason, in order to reduce the maintenance work of the filter, a filter device has been devised in which dust adhering to the air filter is sucked and cleaned by a suction nozzle, and the sucked dust is collected in a dust collector.

  FIG. 6 is a diagram showing the overall configuration of the filter device of the air conditioner in the prior art. In this figure, a filter 4, a heat exchanger 6, and a blower fan 5 are connected to an air passage that connects a suction port 2 provided at the upper front surface and the upper surface of the main body 1 and an air outlet 3 provided at the lower front surface. In order to clean the filter 4, a filter cleaning device 9 that is movably formed on the filter 4 is provided. The filter cleaning device 9 includes the filter cleaning device 9. 9 includes a rotating means 10 that rotates along the inside of the filter 9, a dust removing means 11 that removes dust on the filter 4, and a dust storage portion 12 that stores the dust.

  The dust removing means 11 includes a dust suction portion 13 that is formed so as to be movable on the filter 4, and a suction duct portion 15 that connects the dust suction portion 13 and the dust storage portion 12.

  The dust suction unit 13 is movable in the left-right direction along the fixed rail 16 by driving the winding motor 17.

  With the above configuration, as the dust suction portion 13 of the filter cleaning device 9 moves in the left-right direction on the filter 4, the dust attached on the filter 4 is sucked and carried to the dust storage portion 12.

  Further, the dust suction part 13 of the filter cleaning device 9 moves to the left and right, and the filter 4 is moved in the direction perpendicular to the movement direction of the dust suction part 13 by the rotating means 10 (up and down direction). The dust can be sucked for almost the entire area (see, for example, Patent Document 1).

  Moreover, as a prior art of an air filter, there is one in which a synthetic fiber is woven and a frame is bound as shown in FIG.

As shown in the figure, a filter 1 is formed by integrally forming a mesh-like filter portion 3 between frames 12 and 12a with polypropylene (see, for example, Patent Document 2).

  However, the conventional air filter of the type that is removed and cleaned is generally composed of polypropylene resin fiber, and in this case, the mechanical strength of the polypropylene resin itself is weak, so that the fiber filter such as an air filter is used. When used as a fiber, a fiber diameter of at least a few hundred tens of μm or more is required.

  For this reason, the air filter as a whole has an uneven shape, and it may be difficult to keep the distance between the suction nozzle and the air filter constant at a certain distance, so that sufficient dust cleaning and removal may not be possible.

  In addition, since conventional polypropylene resin fibers have irregularities, the collected dust may be entangled with the air filter and cannot be removed sufficiently by suction alone.

  The present invention solves the above-described conventional problems, and an object thereof is to provide an air conditioner equipped with a filter device that sufficiently removes dust such as dust entangled in an air filter and has high cleaning ability by suction. It is what.

  In order to solve the above-mentioned conventional problems, the air conditioner of the present invention uses polyethylene terephthalate resin as the fiber constituting the air filter that removes dust from the air passing through the heat exchanger.

  With this configuration, the dust collected by the air filter can be hardly entangled with the fibers of the air filter, and the dust can be easily removed by the suction nozzle.

  The air conditioner of the present invention improves the dust releasability of the fiber material constituting the air filter and prevents the air filter from being entangled with the dust by using a suction nozzle. The suction cleaning function enables a configuration capable of exhibiting sufficient cleaning ability.

  1st invention makes the dust which collected with the air filter hard to get entangled with the fiber of an air filter by making the fiber which comprises the air filter which removes the dust of the air which passes a heat exchanger into a polyethylene terephthalate resin. And dust can be easily removed.

  In particular, the second invention includes a filter device including the air filter of the first invention and a filter cleaning device formed on the air filter, and the filter cleaning device includes the air filter as the filter. It is collected by the air filter because it is composed of a rotating means for rotating along the inside of the cleaning device, a dust removing means for removing the dust on the air filter, and a dust container for storing the dust. Dust can be made difficult to get entangled with the fibers of the air filter, and dust can be easily removed by the dust removing means.

3rd invention comprises the filter apparatus comprised by the air filter which removes the dust of the air which passes a heat exchanger, and the filter cleaning apparatus formed on the said air filter, The said filter cleaning apparatus is the said The air filter comprises a rotating means for rotating the air filter along the inside of the filter cleaning device, a dust removing means for removing dust on the air filter, and a dust container for storing the dust. By adopting a shape in which the distance between the removing means and the air filter can be kept constant at a predetermined distance, the dust collected by the air filter can be uniformly removed by the dust removing means.

  In the fourth aspect of the invention, in particular, the air filter according to any one of the first to third aspects has a structure in which the unevenness of the filter network is small, so that dust collected by the air filter is less likely to be entangled with the fibers of the air filter. The dust can be easily removed by the dust removing means.

  In the fifth aspect of the invention, in particular, the air filter according to any one of the first to fourth aspects of the invention has a filter net having a plain weave structure, so that dust collected by the air filter is less likely to get entangled with the fibers of the air filter. And dust can be easily removed by the dust removing means.

  In the sixth aspect of the invention, in particular, the air filter according to any one of the first to fifth aspects has a structure in which the resin layers at the intersections where the fibers of the filter mesh intersect with each other so that the fibers overlap each other. While suppressing the thickness, it is possible to prevent unevenness due to fiber movement and displacement.

  The seventh invention, in particular, comprises the two layers of the filter network of any one of the first to sixth inventions, wherein a high melting point type resin is used for the core wire and a low melting point type resin layer is applied to the surface thereof. By comprising the resin fiber, it is possible to suppress the thickness of the portion where the fibers overlap and to prevent the deviation due to the movement or displacement of the fiber.

  According to an eighth aspect of the invention, in particular, the air filter according to any one of the first to seventh aspects comprises a filter frame having a lattice and a filter net, and the filter frame is molded with an ABS (acrylonitrile butadiene styrene) resin. By using the structure, slack of the filter net can be suppressed.
