Description

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

  As a conventional cleaning device for an air conditioner of this type, there is one as shown in FIG. 13 (see, for example, Patent Document 1).

  FIG. 13 is a perspective view of a conventional air conditioner cleaning device described in Patent Document 1. In FIG.

  In FIG. 13, a conventional air conditioner cleaning device 1 includes a suction nozzle 3 provided with a suction hole 2 for sucking dust, and a suction connected to the suction nozzle 3 via a suction duct 4 having excellent flexibility. An apparatus 5; an exhaust duct 6 connected to the discharge side of the suction device 5 and communicating with the outside; and a driving means 8 for moving the suction nozzle 3 to the left and right along the upstream surface of the air filter 7 of the air conditioner. The suction nozzle 3 is moved along the upstream surface of the air filter 7 from the right end to the left side by the driving means 8 while the suction device 5 is operated, so that the dust accumulated on the air filter 7 is removed. While sucking from the suction hole 2, the sucked dust is discharged to the outside through the exhaust duct 6.

  In the conventional air conditioner cleaning device 1, the dust accumulated on the air filter 7 is sucked and discharged outside the room simply by operating the suction device 5 as appropriate, so that the dust is separately collected and discarded. It is easy to use.

  However, in the case of an air conditioner air filter, the above-described conventional air conditioner cleaning device described above accumulates dust on the surface of the air filter due to moisture from the condensed water generated during the cooling operation of the air conditioner. When the suction hole 2 provided in the suction nozzle 3 is narrowed to increase the suction force so that dust can be easily removed, the suction hole 2 provided in the suction nozzle 3 It takes a long time to clean the entire surface of the wide air filter 7, and if the suction force is increased in the same way, a large suction device 5 is required, which is expensive.

  As a method for solving this, a cleaning device for an air conditioner that corrects and removes dust adhering to the surface of the air filter of an air conditioner with a rotary cleaning body in which a brush-like cleaning body is implanted in the longitudinal direction of the outer periphery. (See, for example, Patent Document 2).

  FIG. 14 is a cross-sectional view of an air conditioner body on which the conventional air conditioner cleaning device described in Patent Document 2 is mounted.

  In FIG. 14, the air conditioner body 10 includes a heat exchanger 11, a suction port 12 for taking in indoor air, and a belt-shaped air filter 13 provided between the heat exchanger 11 and the suction port 12. The drive shaft 15 and the driven shaft 16 in which the air filter 13 is stretched, the servo motor 14 that rotationally drives the drive shaft 15, and the air conditioner cleaning device that removes dust collected by the air filter 13. 17 and a fan 19 that sucks indoor air from the suction port 12 and blows out the heat-exchanged air from the blowout port 18 through the heat exchanger 11 into the room.

  The air conditioner cleaning device 17 includes a rotary cleaning body 20 including a rotor 20a and a brush-like cleaning body 20b planted in the longitudinal direction of the outer periphery of the rotor 20a, and driving means for rotationally driving the rotary cleaning body 20 ( (Not shown), an exhaust pipe 22 that communicates with the suction port 12, has the rotary cleaning body 20 and has a discharge port 21, and a dust discharge fan 23 provided in the exhaust pipe 22. ing.

  The operation and action of the conventional air conditioner cleaning apparatus and air conditioner configured as described above are as follows.

  When the air conditioner main body 10 is in a cooling operation, for example, indoor air flows in from the suction port 12 by the fan 19, passes through the air filter 13, reaches the heat exchanger 11, and is cooled there. 18 is blown into the room. Dust contained in the indoor air to be sucked is collected by the air filter 13 and deposited on the surface of the air filter 13. If dust accumulates on the surface of the air filter 13, the air pressure loss increases and the heat exchange efficiency decreases. Therefore, the dust on the air filter 13 is removed periodically or as necessary. Driving is required.

In the dust removal operation, the servo motor 14 is operated to rotate the drive shaft 15 to continuously move the belt-shaped air filter 13, while rotating the rotary cleaning body 20 and the dust discharge fan 23. As a result, the dust on the air filter 13 is scraped off by the cleaning body 20 b of the rotary cleaning body 20, and the scraped dust is sucked by the dust discharge fan 23 to the outside through the discharge port 21. It is supposed to be discharged.

  However, in the configuration of the conventional air conditioner cleaning device described in Patent Document 2, dust on the cleaning body 20b of the rotary cleaning body 20 easily reattaches to the air filter 13, so that dust can be scraped off. In addition, the dust discharging fan 23 continues to rotate at a high speed while the entire surface of the air filter 13 is being cleaned. Furthermore, since the dust is directly discharged to the outdoors from the discharge port 21, the outdoor air is contaminated with dust, which is unsanitary.

An electric blower 59 that generates suction air and communicates with the opening 38a on the suction side is disposed inside. ing. The electric blower 59 is supported on the inner wall of the suction unit 38 via a support member 60 made of an elastic material. Further, when the dust collection unit 37 is mounted at a predetermined position of the indoor unit 25, the discharge port 37d of the dust collection unit 37 and the opening 38a of the suction unit 38 are communicated with each other.

  The operation and action of the air conditioner cleaning device 35 and the air conditioner indoor unit 25 equipped with the air conditioner cleaning device 35 configured as described above are as follows.

  Normally, as shown in FIG. 1, the dust removal unit 36 is positioned at the lower end of the indoor unit 25, and the dust removal unit 36, the dust collection unit 37, and the suction unit 38 are arranged in a substantially straight line.

  For example, when the indoor unit 25 is in a cooling operation, indoor air flows from the suction port 26a provided in the front panel 26 by the operation of the fan 29, passes through the air filter 27, reaches the heat exchanger 28, and is cooled there. Cold air is blown out into the room from the outlet 30. Dust contained in the indoor air sucked from the suction port 26 a is captured by the air filter 27 and gradually accumulates on the surface of the air filter 27. If dust accumulates on the surface of the air filter 27, the air ventilation pressure loss increases and the heat exchange efficiency in the heat exchanger 28 decreases, so the air filter is periodically or as needed. The operation of removing the dust accumulated on 27 is required.

  Therefore, in this embodiment, when the dust removal operation is started, the second drive means 42 built in the dust removal unit 36 is driven to rotate the rotary cleaning body 40 (in the direction of arrow A in FIG. 2). Rotate). In this state, when the first driving means (not shown) is operated to raise the dust removing unit 36 along the upstream surface of the air filter 27, the raised cloth of the rotating cleaning body 40 that rotates in the meantime. At the tip of 52, dust adhering to the surface of the air filter 27 is scraped off and accumulates in the dust case 41.

  Even when some dust adheres to the raised cloth 52 of the rotary cleaning body 40 when dust is scraped off from the surface of the air filter 27, the raised cloth 52 is scratched by the dust removing body 43. It can be kept clean and dust can be prevented from reattaching to the air filter 27.

  While the dust removing unit 36 is moving on the air filter 27, the discharge port 41c provided in the dust case 41 is closed by the lid body 44 biased downward by a biasing means (not shown). Therefore, the dust accumulated in the dust case 41 does not leak out.

  When the dust removing unit 36 reaches the upper end of the air filter 27, the first driving means is reversed to move the dust removing unit 36 downward.

  When the dust removing unit 36 is lowered to the position shown in FIG. 6A, the lower end of the lid 44 comes into contact with the upper end of the dust collecting unit 37. As shown in FIG. 6B, the dust removing unit 36 When the pressure drops further, the lid body 44 rises against the urging force of the urging means, and finally, as shown in FIG. 6C, the lid body 44 fully opens the discharge port 41c. In addition, the air inlet 37c of the dust collecting unit 37 and the outlet 41c of the dust removing unit 36 are communicated with each other.

  Here, when the suction unit 38 is operated, the check valve 57 is opened by the suction force of the electric blower 59, and the outside air flows in from the opening 41d provided in the dust removing unit 36, and the inside of the dust case 41 together with the outside air. Dust is transferred to the dust collection unit 37 through the discharge port 41c and the intake port 37c. Since the dust collecting unit 37 is provided with a filter 58, the dust trapped there and clean air passes through the discharge port 37 d of the dust collecting unit 37 and the opening 38 a of the suction unit 38, and the electric blower 59. After being cooled, it is discharged to the outside through an exhaust port 38b provided in the rear wall.

  Then, by grasping a handle 37e (see FIG. 1) provided on the front surface of the dust collection unit 37, the dust collection unit 37 is removed from the indoor unit 25, and the lid portion 37b of the dust collection unit 37 is removed on a trash box or the like. The dust inside can be easily discarded. When the dust has been thrown away, it is attached to the original location of the dust collection unit 37.

  As described above, according to the present embodiment, dust attached to the air filter 27 of the air conditioner accumulates in the dust case 41 of the dust removing unit 36 while being reliably scraped off by the rotary cleaning body 40. At the same time, when the dust removal unit 36 moves to a predetermined position, in this embodiment, to the lowermost end, the suction unit 38 is operated, so that the dust accumulated in the dust case 41 is instantaneously absorbed by the suction air. Since the dust collecting unit 37 is moved to the dust collecting unit 37 and the dust collecting unit 37 is detached and the dust can be easily discarded without being scattered around, the maintenance is easy and hygienic.

  Even if dust remains on the rotating cleaning body 40, it is removed by the dust removing body 43, so that the dust attached to the rotating cleaning body 40 does not reattach to the air filter 27. Excellent dust removal performance can be demonstrated. Furthermore, since the suction unit 38 is operated only when the dust in the dust case 41 is moved to the dust collection unit 37, the noise can be reduced as a whole. Further, if the air filter 27 is cleaned several times by the dust removing unit 36 and the dust is sufficiently accumulated in the dust collecting unit 37, then the dust is discarded less frequently and the usability is further improved. To do.

  Further, since the dust collection unit 37 is detachably provided, it is easier to dispose of dust in the dust collection unit 37.

  In the above-described embodiment, the dust collection unit 37 is detachable from the indoor unit 25. However, an appropriate locking portion may be provided on the suction unit 38 so as to be detachably attached to the suction unit 38. .

  In addition, since the dust removing unit 36 is detachably provided in the indoor unit 25, maintenance such as cleaning of the dust case 41, the rotary cleaning body 40, and the dust removing body 43 becomes very easy.

  Further, since the rotary cleaning body 40 is composed of the rod-shaped shaft body 51 and the brush-like raised cloth 52 provided on the surface of the shaft body 51, the dust attached to the air filter 27 can be surely scraped off. , Dust removal performance is improved.

  Moreover, since the brush-like member of the rotary cleaning body 40 is formed of the raised cloth 52 spirally wound around the shaft body 51, the rotary cleaning body 40 can be easily manufactured and the air conditioner cleaning device 35 can be made inexpensively. Can be formed.

  Further, the pile 62c forming the brushed cloth 52, which is a brush-like member, is coated with fluorine resin, silicon resin or the like having excellent slidability, so that dust can be easily separated from the brushed cloth 52. Thus, the reattachment of dust to 27 is less likely to occur, and the dust removal performance is improved.

  In addition, since the inner wall of the dust case 41 is coated with a material having excellent slidability such as fluorine resin or silicon resin, the movement of the dust in the dust case 41 becomes smooth and the suction unit 38 is operated. Then, the dust in the dust case 41 can be reliably moved to the dust collection unit 37.

  Further, since the tip of the dust removing body 43 is formed in a comb blade shape so as to bite into the rotary cleaning body 40, the dust attached to the brushed cloth 52 can be easily taken and the dust reattaching to the air filter 27 is ensured. Can be prevented.

  In addition, by setting the overall width dimension (effective cleaning width dimension) of the raised cloth 52 wound around the shaft body 51 to 500 mm or more, the overall width of the wide air filter 27 installed in the indoor unit 25 of the air conditioner. Then, the raised cloth 52 comes into contact, and even if the rotary cleaning body 40 is rotated at an extremely low speed (for example, about 10 RPM), the air filter 27 can be cleaned sufficiently uniformly. Noise during rotation can be reduced.

  In addition, when the rotary cleaning body 40 is always rotated in one direction and the air filter 27 is cleaned, a part of the dust may be gradually compressed and accumulated on the tip of the dust removing body 43. Therefore, if the rotary cleaning body 40 is reversed every time the suction unit 38 is operated, the compressed and accumulated dust is released, and the dust can be moved to the dust collecting unit 37 more reliably.

  Although not particularly shown, instead of the filter 58 disposed in the dust collecting unit 37, a commercially available disposable paper pack (not shown) for a vacuum cleaner may be used. In this case, the core of the paper pack (not shown) needs to be attached to the air inlet 37c provided in the dust collecting unit 37 so as not to leak air. If the technology adopted in is used, it can be easily configured.

  As described above, when a disposable paper pack is used for the dust collection unit 37, fine dust does not rise when the dust is discarded, and it becomes easier to dispose of dust, and the inside of the dust collection unit 37 is contaminated with dust. This is hygienic and easier to maintain.

  In the above embodiment, the suction unit 38 is a separate component and is attached to the indoor unit 25. However, the suction unit 38 may be formed integrally with a part of the indoor unit 25. Specifically, an electric blower chamber (not shown) for housing the electric blower 59 may be formed in a part of the indoor unit 25 so that the electric blower chamber and the dust collection unit 37 communicate with each other.

  In addition, in the said Example, although the raising cloth 52 was tightly wound around the shaft body 51, when winding the raising cloth 52 around the outer periphery of the shaft body 51 as shown in FIG. If the rotary cleaning body 40 is rotated in the direction of the arrow, for example, it is scraped off from the air filter 27 if the gap 52d between the adjacent raised fabrics 52 is formed in a spiral shape. The gap 52d in which the dust is spirally formed can be moved rightward (in the direction of the white arrow), that is, toward the dust collection unit 37, and the dust can be collected more reliably.
