Description

  The present invention relates to an air filter cleaning device disposed in an air conditioner such as an air conditioner, a blower, a humidifier, a dehumidifier, a ventilation fan, or an air purifier, and an air conditioner using the same.

  In a conventional air conditioner, an air filter is disposed between the suction port and the heat exchanger to prevent dust from entering the air conditioner body, and air flows from the suction port as the air conditioner operates. And has a function of catching intruding dust. For this reason, the dust trapped on the air filter gradually adheres, and the eyes gradually clog and reduce the air volume. It had to be sucked and cleaned with a vacuum cleaner.

  On the other hand, in the air conditioner body, slide means for reciprocating the air filter toward the inside and outside of the main body cabinet, and air arranged so as to contact the air filter along the movement path of the air filter. The filter is structured so that it is sandwiched from both sides. By sliding the air filter, both sides of the air filter can be cleaned with a cleaning brush, and dust collected in the air filter cleaning unit is opened and closed. A structure has also been devised that can be easily recovered by performing (see, for example, Patent Document 1).

  Further, with respect to the conventional twisting brush, various improvements are made according to the purpose of use. For example, synthetic fiber single yarns are gathered, a plurality of converging yarns to be twisted are combined, and an upper twist is applied. In addition, the synthetic fiber single yarn is bonded with an adhesive to form a hair material, and a plurality of the hair materials are sandwiched between at least two core materials, twisted, fixed to the core material, The technique of the twist brush for application | coating which became the state which unraveled the front-end | tip is published as an application brush which can improve liquid retention (for example, patent document 2).

  However, in the conventional air conditioner disclosed in the above-mentioned document 1, since the air filter is sandwiched between the cleaning brushes, dust on both sides of the air filter can be cleaned at the same time. A cleaning brush that moves at a speed can only scratch the surface of the air filter and has little effect of rubbing. It can remove cotton dust that floats on the surface of the air filter, but it is entangled in the mesh of the air filter. In order to scrape off dust or oil-containing dust, it cannot be scraped out until it is completely peeled off, and it is difficult to reliably remove dust stuck to the air filter.

  As shown in FIGS. 2A and 2B, the conventional torsion brush 7 is twisted by sandwiching a brush piece 9 between two circular core wires 8, and the brush piece 9 is formed of two core wires 8. Each one was pinched and twisted at only one point. 2 (C) and 2 (D) and any one of the dust removing bodies 10, 30, 31, 32, 33, 34, 35, 36, 37, 38 in FIGS. Also in 39 and 40, since the brush piece 9 is pinched and twisted on the line of the fixed area in the outer peripheral surface of a cross section like the core wire 11-core wire 22, compared with the conventional torsion brush 7, the brush piece 9 The pull-out strength from the core wire increases. In addition, since the conventional torsion brush 7 is twisted with the brush piece 9 sandwiched between two circular core wires 8, the torsion brush 7 is likely to be greatly bent in the longitudinal direction and has a large shape deformation due to the bending. It was. The dust removing bodies 10, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, and 40 that twist the core wire 11 to the core wire 22 with respect to the torsion brush 7 are the core wire 11 to the core wire 22. Since the cross section is a shape that can be sandwiched and twisted on a line of a certain section on the outer peripheral surface, the dust removing bodies 10, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 While being able to strengthen, since bending of a longitudinal direction can be suppressed very little, shape deformation by bending can be suppressed.

  Moreover, since the core wire which has a square-shaped cross section like the core wire 15 used for the dust removing body 32 in FIG. 3C can form four corners, the core wire has a round cross section. In comparison, shape deformation due to bending can be suppressed. For example, in the case of a square-shaped section having the same cross-sectional area of 1 square millimeter and a round-shaped section, the length between the facing corners of the square-shaped section is 1.414 mm, and the round-shaped section is The diameter of the cross section is 1.128 mm, and a square-shaped cross section can form a length between facing corners of about 1.25 times that of a round cross section. Therefore, a core wire having a quadrangular cross section can suppress shape deformation due to bending compared to a core wire having a round cross section.

  A second embodiment of the present invention will be described with reference to FIG. (A) is a cross section of the dust removing body 41 twisted with the brush piece 24 sandwiched between three circular core wires 23. (B) is a cross section of the dust removing body 42 twisted with the brush piece 24 sandwiched between four circular core wires 23. (C) is a cross section of the dust removing body 43 that is twisted with the brush piece 24 sandwiched between four circular core wires 23 and one circular core wire 53.

  In any of the dust removing bodies 41, 42, 43, the brush piece 24 is twisted by being sandwiched on a line of a certain section in the cross section of the core wire 23, and the removal strength of the brush piece 9 from the core wire 8 in the conventional torsion brush 7. In comparison with this, since the degree of adhesion of the brush piece 24 to the core wire 3 increases, the strength of the brush piece 24 coming off from the core wire 23 increases. Further, since the dust removing body 43 is twisted with the brush piece 24 sandwiched between the core wire 23 and the core wire 53, compared with the dust removing body 42, the mechanical strength and the removal of the brush piece 24 from the core wire 23 are increased. Can have strength. Further, the dust removing bodies 41, 42 and 43 formed by twisting three or more core wires 23 have a greater mechanical strength than the torsion brush 7 formed by twisting the two core wires 8. I can do things. Therefore, the waist can be strengthened, and the bending in the longitudinal direction can be suppressed very little, so that the shape deformation due to the bending can be suppressed. Therefore, it is possible to make a cleaning device having dust removing bodies 41, 42, and 43 having strong waists, little bending, and a long total length.
