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 caught 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, a suction nozzle having a suction port that can move along the upstream surface of the air filter, and a suction device connected to the suction nozzle are provided in the air conditioner body, and the air filter surface from the suction port. A structure has been devised in which the air filter can be automatically cleaned without removing the air filter by sucking the dust adhering to the air (see, for example, Patent Document 1).

  Also, in the air conditioner main body, the air filter is disposed so as to contact the air filter along the moving path of the air filter, and slide means for reciprocating the air filter toward the inside and outside of the main body cabinet. And a structure in which the air filter is sandwiched from both sides with a cleaning brush provided in the air filter cleaning unit, both sides of the air filter can be cleaned with the cleaning brush by sliding the air filter, and A structure has also been devised in which dust collected in the air filter cleaning unit can be easily collected by opening and closing the air filter cleaning unit (see, for example, Patent Document 2).

  However, in the conventional air conditioner disclosed in Patent Literature 1, the suction pressure is increased by reducing the air volume by reducing the opening / closing area of the suction port. If you try to remove dust with such a suction nozzle, you can easily suck cotton dust and the like that floats on the surface of the air filter. In addition, dust containing oil and the like cannot be scraped off and removed like a cleaning brush, and it is very difficult to reliably remove dust stuck to the air filter.

  Further, in the conventional air conditioner disclosed in Patent Document 2, 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 high speed only scratches the surface of the air filter and has little effect of rubbing, and can remove cotton dust that floats on the surface of the air filter. In order to scrape off dust or oil-containing dust, it cannot be scraped until it is completely peeled off, and it is very difficult to reliably remove dust stuck to the air filter.

  Further, the removed dust enters between the fibers of the cleaning brush, and the cleaning brush itself becomes dirty. Furthermore, dust that has entered between the fibers of the cleaning brush may re-adhere to the air filter surface while the air filter cleaning is repeated. It also had the disadvantage of having to be cleaned.

  The present invention is for solving the above-described conventional problems, and dust attached to the air filter of the air conditioner can be efficiently and surely removed, and dust attached to the cleaning brush itself can be removed, An object of the present invention is to provide an air conditioner cleaning apparatus and an air conditioner that can be used in a clean state without deteriorating the dust removal effect and without being clogged with an air filter for a long period of time.

  In order to solve the above-mentioned conventional problems, in the present invention, in an air conditioner in which an air filter for dust removal is arranged in an air passage connecting a suction port and an outlet provided in a main body, the end of the air filter There is a dust removing body A in the vicinity, there is a dust removing body B that overlaps the dust removing body A, and the dust removing body B returns to a position facing the dust removing body A and a cleaning process that moves at least on the surface of the air filter. Since the cleaning process is included, the dust attached to the air filter of the air conditioner can be removed by the dust remover B, and the dust attached to the dust remover B can be removed by the dust remover A.

  This prevents dust from accumulating on the dust removing body B and prevents the dust from reattaching to the air filter. Therefore, the air filter can always be clean and used for a long time without clogging. Therefore, the performance of the air conditioner is maintained, and it is not necessary to remove the air filter and clean the dust.

  Moreover, the air conditioner of this invention arrange | positions the air filter for dust removal in the air path which connects the suction inlet provided in the air conditioner main body, and the blower outlet, In any one of Claims 1-5 Since it has a cleaning device, dust attached to the air filter can be removed efficiently and reliably, and further, dust attached to the dust remover itself can be removed, so that the air flow rate of the main body is extremely small and power consumption is suppressed. be able to. In addition, maintenance of the air filter and the dust remover is unnecessary for a long period of time.

  The cleaning device of the present invention has a dust removing body A in the vicinity of an air filter end portion, a dust removing body B that overlaps the dust removing body A, and the dust removing body B moves at least on the surface of the air filter; Since it has a cleaning process to return to the position facing the dust removing body A, the dust attached to the air filter is removed by the dust removing body B, and further, the dust attached to the dust removing body B is removed by the dust removing body A. As a result, the air filter can be used for a long period of time without clogging the air filter, so that the performance of the air conditioner is maintained, and it is necessary to remove the air filter and clean the dust. Also disappear.

A first invention is an air conditioner in which an air filter for dust removal is disposed in an air passage connecting a suction port and a blowout port provided in a main body, and there is a dust removing body A in the vicinity of the end of the air filter, Since there is a dust removing body B facing the dust removing body A, the dust removing body B has at least a cleaning process of moving on the air filter surface and a cleaning process of returning to a position facing the dust removing body A. The dust attached to the air filter of the air conditioner can be removed by the dust remover B, and the dust attached to the dust remover B can be removed by the dust remover A.

  The second invention is attached to the dust removing body B because the dust removing body A and / or the dust removing body B makes a reciprocating motion at least once in a state where the dust removing body A and the dust removing body B of the first invention are facing each other. The removed dust is removed by the dust remover A, and the dust adhering to the dust remover A can also be collected in a separately provided dust collection case or the like by repeating the reciprocating motion.

  In the first or second invention, the third invention has a cleaning process in which only the dust remover B moves away from the dust remover A and moves on the surface of the air filter. Therefore, the dust remover A can be fixed. In addition, since only the dust removing body B needs to be moved, space saving can be achieved and the air conditioner body can be downsized.

  In the fourth invention, since the dust remover of the dust remover A and / or the dust remover of the dust remover B of the first to third inventions is inclined, the dust remover A and the dust remover of the dust remover B face each other, or By reciprocating in a state of overlapping each other, the dust attached to the dust removing body A and the dust removing body B can be reliably moved to the inclined side of the dust remover. It is possible to collect dust easily.

  In the fifth invention, the dust remover of the dust remover A of the first to fourth inventions is inclined to the anti-air filter side, and the dust remover of the dust remover B is opposed to the dust remover of the dust remover A. When the dust remover B moves on the surface of the air filter toward the position facing the dust remover A because it is inclined to the side opposite to the air filter, the dust remover of the dust remover B is attached to the air filter. When the dust removing body B overlaps with the dust removing body A, the dust attached to the dust removing body B is scraped off by the dust remover of the dust removing body A, and the dust attached to the dust removing body A is also Since it can be reliably moved to the anti-air filter side, dust can be easily collected in a separately provided dust collection case or the like.

  Since the sixth invention has the cleaning device of any of the first to fifth inventions in the air conditioner body, dust removal from the air filter that is efficient by the dust removal body A and dust removal body B, and Since dust can be collected, it is possible to provide an air conditioner that does not cause clogging of the air filter, can always secure a stable air volume, and has high operating efficiency.

An air conditioner cleaning apparatus according to an embodiment of the present invention will be described with reference to FIGS.
In FIG. 1, an air conditioner body 1 is arranged between a heat exchanger 4, a suction port 2 for taking in indoor air, the heat exchanger 4 and the suction port 2, and flows from the suction port 2. An air filter 5 that collects dust contained in the air, a dust removing body B7 that is disposed upstream of the air filter 5 and that removes dust collected by the air filter 5, and the dust removing body B7 Is moved in the vertical direction along the upstream surface of the air filter 5, and is provided in the vicinity of the lower end of the air filter 5 to remove the dust adhering to the dust removing body B7. The air in the room is sucked from the dust collection case 9 in which the dust removing body A8 is built in and the suction port 2 and the air is exchanged through the air filter 5 and the heat exchanger 4 from the blowout port 3. With fan 6 It is provided.

Next, the structure of the dust removing body B7 and the dust removing body A8 will be described with reference to FIGS.
In FIG. 2, the dust remover B7 is composed of a base 12 and a pile-shaped dust remover 10 that is implanted in the base 12 and has a tip inclined in one direction. The back of the base 12 is made of synthetic resin or metal. The dust filter 10 is adhered to the air filter 5 uniformly by adhering to a base 13 that is made and linearly formed with a length substantially equal to the distance in the longitudinal direction of the air filter 5. At this time, the tip of the dust remover 10 is inclined downward.

  In FIG. 3, 9 is a dust collection case for finally collecting the dust adhering to the dust remover B7, and includes a dust remover A8. The dust removing body A8 is composed of a base portion 14 and a pile-shaped dust remover 11 which is implanted in the base portion 14 and has a tip inclined in one direction in the same manner as the dust removing body B7. It is fixed to the inner wall of 9 by a method such as adhesion. The tip of the dust remover 11 is inclined downward, that is, toward the anti-air filter.

  As described above, since the tip of the dust remover 10 of the dust remover B7 is inclined downward, when the dust remover B7 is housed in the dust collecting case 9, the dust remover 10 is relatively rubbed with the dust remover A8. It is inclined downward, that is, toward the side opposite to the air filter. Further, in the dust collecting case 9, a space portion 15 into which the dust removing body B7 can enter is secured at a position facing the dust removing body A8.

  In the above description, the dust remover 7B and the dust remover 10 in the dust remover 8A and the dust remover 11 are described as piles. However, the material is not limited to this, and the material is not limited to this. Resin, metal, etc. can be selected as appropriate. Similarly, the shape of the dust remover 10 and the dust remover 11 can be appropriately selected such as a needle shape or a fin shape.

  Next, operation | movement of the air conditioner carrying the cleaning apparatus which uses the dust removal body in a present Example is demonstrated.

  When the air conditioner main body 1 is in a cooling operation, for example, indoor air flows from the suction port 2 by the blower fan 6, passes through the air filter 5, reaches the heat exchanger 4, and is cooled there, and the cold air is blown out. It blows out into the room from the mouth 3. Dust contained in indoor air sucked from the suction port 2 is collected by the air filter 5 and gradually accumulates on the surface of the air filter 5. If dust accumulates on the surface of the air filter 5, air pressure loss of the air increases and the heat exchange efficiency in the heat exchanger 4 decreases. Therefore, the air filter may be periodically or as needed. 5 is required to remove dust accumulated on 5.

  At the start of the dust removal operation, the dust remover B7 is positioned near the lower end of the air filter 5. When the dust removal operation is started, the dust removing body B7 moves upward along the surface of the air filter 5 by the vertical movement means (not shown). During this time, the tip of the dust remover 10 is not in contact with the air filter 5.

  Next, when the dust removing body B7 reaches the upper end of the air filter 5 by the vertical movement means (not shown), the dust removal body B7 is also moved downward along the surface of the air filter 5 by the vertical movement means. At this time, the tip of the dust remover 10 of the dust remover B 7 moves downward while contacting the surface of the air filter 5, so that the dust adhering to the surface of the air filter 5 is collected in the dust remover 10.

  When the dust remover B7 moves downward on the surface of the air filter 5 as described above, the tip of the dust remover 10 of the dust remover B7 leads to the surface of the air filter 5 with the tip leading in the direction of travel. Because of the contact, the air filter 5 is strongly scratched, and the dust stuck on the surface can be easily removed.

  In the present embodiment, when the dust remover B7 moves upward along the surface of the air filter 5, the tip of the dust remover 10 moves backward with respect to the traveling direction, so that the dust filter B7 is not in contact with the air filter 5. However, when aiming at a polishing effect or the like by making smooth contact, the dust remover 10 may be brought into contact also when moving upward.

  Although not shown, when the dust remover 10 is not inclined, the dust can be removed both in a reciprocating manner by contacting the air filter 5 during both vertical movements.

Next, the cleaning process of the dust adhering to the dust removing body B7 will be described with reference to FIGS.
The dust removing body B7, which has moved up and down the surface of the air filter 5 to remove dust by means of vertical movement means (not shown), moves into a dust collecting case 9 provided near the lower end of the air filter 5, As shown in FIG. At this time, the dust 16 attached to the dust remover 10 of the dust remover B7 is sandwiched between the dust remover 11 of the dust remover A8 in the dust collection case 9.

  Next, as shown in FIG. 4, the dust remover B7 moves in the direction of arrow C, that is, toward the air filter. At this time, the dust 16 is scraped off into the dust collecting case 9 by the inclined dust remover 11 of the dust removing body A8.

  Furthermore, as shown in FIG. 5, the dust remover B7 moves again in the direction of the arrow D, that is, to the side opposite to the air filter. At this time, the dust 16 attached to the dust remover 11 of the dust remover A8 is scraped off by the inclined dust remover 10 of the dust remover B7 to scrape the dust 16 downward.

  In this manner, the dust remover B7 is gradually reciprocated in the directions of arrows C and D while facing the dust remover A8 in the dust collection case, so that the dust 16 originally attached to the dust remover B7 gradually increases. Then, it moves downward, that is, to the anti-air filter side, and finally all is collected into the dust collecting case 9. Further, the same effect can be obtained even if the dust removing body A8 is reciprocated with the dust removing body B7 fixed.

  As described above, the dust collecting body B7 is reciprocated relative to the dust removing body A8 and repeats the reciprocating motion. As a result, the dust collecting effect is most enhanced. The dust can be collected in the dust collection case 9 by entering the case 9 and staying in a position facing the dust removing body A8 and moving again to the outside of the dust collection case 9.

  Further, in this embodiment, both the dust remover 10 of the dust remover B7 and the dust remover 11 of the dust remover A8 are inclined in the same direction to enhance the dust collection effect. Even if only one of them is inclined, the dust collecting effect is produced.

  In this embodiment, since only the dust removing body B7 moves on the surface of the air filter 5 to remove dust, there is no need to move the dust collecting case 9 including the dust removing body A8, and the air filter 5 and the suction port Since the space between the two can be reduced, the size of the air conditioner body can be reduced.

  In addition, since it is not necessary to move the dust collection case 9 including the dust removing body A8, the vertical movement means (not shown) can be simplified and a complicated structure is not required. Furthermore, reattachment of dust to the dust remover B7 can be prevented.

  Although not shown in particular, the effect of the present invention can be obtained even when the dust removing body B7 moves together with the dust collecting case 9 including the dust removing body A8.

  As described above, by providing the cleaning device of the present invention in the air conditioner main body, the air filter 5 is not clogged, a stable air volume can be always secured, and the operation efficiency is good, so the performance is also maintained. The power consumption of the air conditioner can also be saved. Moreover, it is not necessary to remove the air filter 5 and clean the dust, and it is only necessary to periodically remove the dust collecting case 9 and discard the accumulated dust, so that the frequency of maintenance can be greatly reduced.

  It is also possible to suck and collect dust accumulated in the dust collecting case 9 by providing a separate suction device (not shown).

  As described above, the air conditioner cleaning device and the air conditioner according to the present invention have excellent performance as an air filter cleaning device, and are air conditioners and air purifiers as well as devices having an air filter. If there is, it can be applied to the cleaning device of the air filter.
