Description

  The present invention is equipped with a filter cleaning device, in particular, a filter cleaning device that automatically removes dust, dust, lint, etc. (collectively referred to as “dust” in the present invention) captured by the filter, and such a filter cleaning device. It is related to the air conditioner.

  2. Description of the Related Art Conventionally, an air conditioner having a filter cleaning device function capable of removing dust attached to a filter by moving the filter and easily collecting the removed dust has been disclosed (for example, see Patent Document 1). ).

In addition, the filter of the conventional air conditioner and filter cleaning device is such that the horizontal beam of the filter is connected by a continuous straight line from one outer end of the vertical beam to the other outer end, and the horizontal beam is orthogonal to the vertical beam. (See, for example, Patent Document 2).
JP 2004-28487 A (page 5-8, FIG. 1) JP 2003-071215 A

However, the air conditioner disclosed in Patent Document 1 has the following problems.
(A) The filter in the filter cleaning section is pushed out of the machine while pushing up the open / close panel provided on the front panel of the air conditioner during cleaning, that is, the filter is visually recognized from the inside, so the design of the apparatus As a result, the cleanliness of the device is impaired and the occupants may feel uncomfortable and the competitiveness of the product is reduced.
(Ii) Since the filter moving mechanism in the filter cleaning section includes a rack formed at the center in the width direction of the filter, a pinion that rotates in mesh with the rack, and a drive motor that rotates the pinion. If multiple filters (same for multiple filter cleaning units) are installed in the air conditioner, the drive motor will become more than one, resulting in increased manufacturing costs, increased equipment weight, and an air conditioner equipped with this. The product becomes less competitive as it increases size and restricts design.

  Moreover, when using the filter disclosed by the said patent document 2 for a filter cleaning apparatus, when a filter moved and passed a dust removal part, there existed a subject that a horizontal cross became resistance and a filter did not move smoothly.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a filter cleaning device capable of smoothly moving a filter and an air conditioner using the same.

The filter according to the present invention is a filter used in a filter cleaning device having a filter moving unit for moving a filter,
  A rectangular outer frame, a vertical beam that connects opposite sides of the outer frame and is formed in the direction of movement of the filter, and a horizontal beam that linearly connects adjacent vertical beams. The horizontal beams on both sides of the vertical beam excluding the vertical beam are arranged so as not to be a continuous straight line, and the filter driven gear meshing with the filter driving gear of the filter moving unit is provided in the central vertical beam, It is characterized by being symmetrical with respect to

By using the filter according to the present invention, in the filter cleaning device, the resistance of the horizontal beam when the filter passes through the dust removing unit is dispersed, and the resistance of the horizontal beam when passing through the dust removing unit is also symmetrical. Thus, the filter can be moved smoothly.

(filter)
FIG. 3 is a diagram showing the first embodiment, and is a plan view of the filter 40. In FIG. 3, the filter 40 is formed of a net-like filter vent 41 and a filter frame 42 on which the filter vent 41 is installed. The filter frame body 42 forms a part of a cylinder (having a so-called “eight bridge shape” having a circular arc cross section), and a vertical beam 102 that connects a rectangular outer frame 43 and opposing sides of the outer frame 43. And a horizontal crosspiece 101 connecting the vertical crosspieces 102, and a filter driven gear 45 (see FIG. 5) formed of an internal gear is formed on the inner surface of the vertical crosspiece 102.

  The filter 40 is guided by a rail portion (not shown) and reciprocates along the arcuate movement path 17 in a range where the upper edge reaches the position A and the lower edge reaches the position B. Thus, the radius of curvature of the arc of the cross section of the filter frame 42 (same as the filter 40) is the same as the radius of curvature of the arcuate moving path 17. That is, since the filter 40 reciprocates without changing the radius of curvature, not only can the filter 40 be moved by simple means, but the deterioration of the filter 40 itself is prevented and the life is extended.

  The horizontal rails 101 of the filter 40 are linearly connected between adjacent vertical rails 102, and the horizontal rails 101 on both sides of the vertical rail 102 excluding the central vertical rail 102 are arranged so as not to be a continuous straight line. The filter 40 is symmetric with respect to the central vertical beam 102.

  4 is a cross-sectional view taken along line YY of FIG. As shown in FIG. 4, the cross section of the horizontal rail 101 has an arc shape.

  FIG. 5 shows the first embodiment and is a perspective view of the inside of the filter 40. As shown in FIG. 5, a filter driven gear 45 composed of an internal gear is formed on the inner surface of the central vertical beam 102. And the guide rib 103 is formed in the inner surface of the other vertical beam 102 over the full length.

  FIG. 6 shows the first embodiment, and is a partial cross-sectional view in the vicinity of the filter guide portion 104. As shown in FIG. 6, a filter guide portion 104 that guides the guide rib 103 of the filter 40 is formed in the filter moving portion 60.

(How to move the filter)
A procedure for moving the filter 40 in the filter cleaning device 50 shown in FIG. 1 will be described. The filter 40 moves along the arcuate moving path 17 from the state where the upper edge 46 is at the position A until the lower edge 47 reaches the position B.

  In the “outward path” from position A to position B, the roll brush 71 rotates in the same direction (clockwise in the figure) as the moving direction of the filter 40 (substantially downward in the figure). Dust trapped in the gas 41 is removed. In particular, since the peripheral speed (Vb) of the roll brush 71 is slower (Vb <Vf) than the moving speed (Vf) of the filter 40, the dust trapped in the filter vent 41 is temporarily removed from the roll brush. After being collected on the biting side of 71 (the top surface side in the figure), it adheres to the roll brush 71 and is carried to the biting side (the ground side in the figure). The attached dust is scraped off by the scraping plate 81 and collected in the dust collection box 83.

  On the other hand, the filter 40 that has reached the lowering limit is moved by the filter drive gear 61 that rotates in the reverse direction (clockwise in the drawing) and returns to the rising limit (see FIG. 1). That is, the upper edge 46 reaches the position A.

  In the “return path” from the position B to the position A, the roll brush 71 stops rotating. Therefore, even if the dust that has not been removed in the forward path is removed in the return path, the dust is only collected on the biting side (the ground side in the figure) of the roll-shaped brush 71 that is not rotating. It is not carried to the delivery side (the top side in the figure). Therefore, the dust removed from the roll-shaped brush 71 does not dissipate out of the dust collection box 83.

When the filter 40 of the filter cleaning device 50 moves, the cross rail 101 passes through the dust removing unit 70. The horizontal crosspieces 101 are linearly connected between the adjacent vertical crosspieces 102, and the horizontal crosspieces 101 on both sides of the vertical crosspiece 102 excluding the central vertical crosspiece 102 are arranged so as not to be a continuous straight line, And by making the cross-sectional shape of the horizontal crosspiece 101 into an arc, the resistance of the horizontal crosspiece 101 when the filter 40 passes the dust removal part 70 becomes small, and the filter 40 can be moved smoothly. Further, by arranging the horizontal rails 101 of the filter 40 symmetrically, the resistance of the horizontal rails 101 when passing through the dust removing unit 70 is also symmetrical, and the filter 40 can be moved smoothly. Have.

  Moreover, since the guide rib 103 is provided inside the filter 40 and the filter guide part 104 for guiding the guide rib 103 of the filter 40 is formed in the filter moving part 60, the filter 40 can be moved smoothly.

  As shown in FIG. 8, the horizontal beam 101 of the filter 40 is formed obliquely so as not to be orthogonal to the vertical beam 102. Adjacent vertical bars 102 are linearly connected by horizontal bars 101. The horizontal rails 101 on both sides of the vertical rail 102 excluding the central vertical rail 102 are arranged so as not to form a continuous straight line. The filter 40 is symmetric with respect to the central vertical beam 102.

  The horizontal beam 101 of the filter 40 is formed obliquely so as not to be orthogonal to the vertical beam 102, the adjacent vertical beams 102 are linearly connected by the horizontal beam 101, and the horizontal beam on both sides of the vertical beam 102 except for the central vertical beam 102. By arranging the crosspiece 101 so as not to be a continuous straight line, the resistance of the horizontal crosspiece 101 when the filter 40 passes through the dust removing unit 70 is reduced, and the filter 40 can be moved smoothly.

  In the first to third embodiments, the air conditioner 100 uses one filter 40. However, the present invention is not limited to one, and a plurality of filters 40 may be arranged side by side. Good.
