Description

  The present invention relates to an air conditioner including a cleaning device that cleans a filter attached to the air conditioner.

  As a conventional cleaning device for an air conditioner of this type, there is the following one.

  A conventional air conditioner equipped with a cleaning device for an air conditioner includes a filter having an arc-shaped cross section that reciprocates in a housing along an arcuate moving path, and a filter driving gear that meshes with a filter driven gear formed in the filter. A roll brush for removing dust trapped by contacting the outer surface of the filter, a scraping plate for scraping off the dust trapped by contacting the roll brush, and a dust collection box for storing the scraped dust ,have.

Since the filter cleaning apparatus according to the conventional air conditioner moves along the arcuate movement path in the housing, the filter can be cleaned without protruding the filter outside the housing, And since a filter is not visually recognized from the exterior of a housing | casing, while the designability improves, it has the characteristics that the cleanliness of an apparatus increases.
JP 2007-292399 A

  However, in the above conventional air conditioner cleaning device, the filter formed in the cross-section arc shape reciprocates in the housing, so that it is possible to capture dust contained in the air flowing in from the suction port. Even when the dust is removed from the filter with a roll brush, the filter is kept in a circular arc shape with a constant cross section, so the mesh of the filter is not deformed, and the force that makes the roll brush contact the mesh Only dust was removed. For this reason, there has been a problem that dust that has entered the mesh of the filter cannot be removed sufficiently.

Furthermore, the conventional air conditioner cleaning device has a problem that the filter is arc-shaped, and thus an arc-shaped space is required on the rear side of the cover, and the casing of the air conditioner is enlarged. .
Wall-mounted air conditioners are required to be thin in view of the aesthetics of the room and light in weight to protect the strength of the walls. Recently, dust trapped in a dust collector (filter) is automatically collected. As a result, the user convenience is expected to improve.

  The present invention solves the above-described conventional problems, and has an object to provide an air conditioner having a filter cleaning device having good dust scraping performance and a thin main body. .

In order to solve the conventional problems, an air conditioner according to the present invention forms a ventilation air passage between a suction port and a blowout port in a body case having a suction port and a blowout port, A dust collector comprising a dust collector formed of a filter and a frame on the upstream side in the road, a blower on the downstream side, and a trapping brush and a dust collection chamber for contacting the upstream surface of the dust collector and collecting the dust Each of the dust collecting bodies is formed in a flat plate shape in a guide passage body formed in a substantially L shape having a pair of bent portions and a straight portion provided facing each other in the main body case. And at least the frame is formed of a flexible member so as to be bent, and is supported movably by supporting portions provided on the side portions on both sides of the dust collector , and a part thereof is joined to the driver. The dust collector is the bent portion of the guide passage body. Be those in contact with the bent portion to the vicinity of the more bent the dust collection body increases, the dust collection body, in any one of the operation before and after the start of the blower, and lowered the guide passage body by said drive member At least one reciprocating movement of the dust collector, and a part of the dust collector is exposed from a descending groove formed on the front surface of the main body case at the time of lowering. When the dust collector is stopped, the dust collector catches the dust in a straight line, and when cleaning, that is, when the dust collector is movable, the dust collector also bends when passing through the bent portion. The reaction force that floats to the side works, and the dust is easily separated from the dust collector. The dust collector provided so as to be in contact with the bent portion can reliably and efficiently remove the dust that has been easily separated. In addition, by disposing the dust collector along the shape of the main body case, it is possible to eliminate the useless space and reduce the thickness of the main body.

  In the air conditioner of the present invention, the dust collector is formed into a flat plate shape, and at least the frame is formed of a soft member so as to be bent, and the dust collector changes from a straight shape to a bent state. Sometimes the reaction force is easy to work and has an effect of making it easy to separate dust. Further, since the dust collector is formed in a flat plate shape, the mold is not complicated and a bent portion or the like is not required, so that the space for transporting and storing the dust collector is also improved. Moreover, by forming with a soft material, the shape of the main body case, that is, the design can be selected relatively freely.

  In the air conditioner of the present invention, the dust collector is moved at least one reciprocation of the descending and ascending in the guide passage body by the driver either before or after the start of the operation of the blower. A part of the aggregate is exposed from a descent groove formed on the front surface of the main body case, and the dust collector is lowered from the vicinity of the suction port to a predetermined position by the driver before or after the blower is started. Since the dust collected on the upstream side of the dust collector is reliably removed by the dust collector by reciprocating at least one reciprocating movement that moves up to the vicinity of the suction port, the filter is not clogged. In addition, the passing air moves smoothly and does not impose a load on the blower. Further, since there is no decrease in the processing air volume, for example, cooling and heating capabilities are maintained.

  Furthermore, since the dust collection work by the dust collector from the dust collector can be made visible to the user by exposing a part of the dust collector from the descending groove provided on the front surface of the main body, the user can Can also be relieved. Although there are conventional examples in which most of the filters are exposed, it is not preferable from an aesthetic point of view.

  Further, the air conditioner of the present invention is provided with a guide body disposed at a substantially intermediate portion between the pair of guide passage bodies so as to contact the downstream surface of the dust collector and to face the capture brush. The dust collector is composed of a soft member, and its both side parts are supported by the guide passage body, so there is no problem such as deformation, but the center part is not supported. Easy to deform. For this purpose, by providing a guide body that contacts the downstream surface side of the substantially central portion, the dust collector is supported in a sandwich shape with the capture brush so as to reliably prevent deformation and press contact with the capture brush. Therefore, the dust collected on the upstream surface of the filter can be reliably collected by the capture brush and the dust collection efficiency can be improved.

  The effect of claim 1 is that when the air conditioner is operating, that is, when the dust collector is stopped, the dust collector captures the dust in a straight line, and is bent when cleaning, that is, when the dust collector is movable. Since the dust collector also bends as it passes through the section, a reaction force that causes the dust to float upstream acts and the dust is easily separated from the dust collector. The dust collector provided so as to be in contact with the bent portion can reliably and efficiently remove the dust that has been easily separated.

Furthermore, by disposing the dust collector along the shape of the main body case having a bent portion, the useless space is eliminated and the main body can be thinned. In addition, a pair of guide passage bodies having bent portions in part on both side surface portions of the main body case are provided, and a dust collector made up of a flat plate-like filter and a frame plate is forcibly formed in the guide passage body. And a movable body that is movably supported and movable so that the dust collector can be moved up and down, and further, the bent portion on the upstream side of the dust collector forcibly formed with the bent portion by the guide passage body. By placing the trapping brush on the dust collector in the vicinity, when the dust collector descends the guide passage body, centrifugal force acts away from the guide passage body at the bent part, but the dust collector catches it. The force is blocked and can be moved smoothly.
At this time, the dust collecting brush is in pressure contact with the upstream side surface of the dust collecting member so that it can catch more dust, and its collecting efficiency is improved. Also. Since the capture brush can be rotated to reduce contact resistance, the vertical movement of the dust collector can be moved more smoothly, which helps to reduce the size of the drive body and also to reduce the thickness and weight of the device. .

Further, since the dust collector is formed in a flat plate shape, the mold is not complicated and a bent portion or the like is not required, so that the space for transporting and storing the dust collector is also improved. Further, when the dust collector is changed from a straight shape to a bent state, a reaction force is easily exerted, and the dust is easily separated. Moreover, by forming with a soft material, the shape of the main body case, that is, the design can be selected relatively freely.

In addition, the dust collector is moved by at least one reciprocating movement that is lowered from the vicinity of the suction port to a predetermined position by the driver before starting the operation of the blower or after the operation is stopped. Since the dust collected on the upstream side of the collection is surely removed by the collection, there is no clogging of the filter, the passing air moves smoothly, and no load is applied to the blower. Further, since there is no decrease in the processing air volume, for example, cooling and heating capabilities are maintained. Furthermore, since the dust collection work by the dust collector from the dust collector can be made visible to the user by exposing a part of the dust collector from the descending groove provided on the front surface of the main body, the user can Can also be relieved. Although there are conventional examples in which most of the filters are exposed, it is not preferable from an aesthetic point of view. Further, when cleaning is performed with the filter removed, the filter can be easily removed by holding the exposed portion of the filter, so that maintenance can be easily performed.

The effect described in claim 2 is that the dust collector is composed of a soft member, and both side portions thereof are supported by the guide passage body, so there is no problem of deformation or the like, but the center portion is not supported. In particular, it is easily deformed when it is movable up and down. For this purpose, by providing a guide body that contacts the downstream surface side of the substantially central portion, the dust collector is supported in a sandwich shape with the capture brush so as to reliably prevent deformation and press contact with the capture brush. Therefore, the dust collected on the upstream surface of the filter can be reliably collected by the capture brush and the dust collection efficiency can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this Example.

Example 1
An air conditioner cleaning mechanism and an air conditioner equipped with the same in a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is an external view of an air conditioner according to the present embodiment, FIG. 2 is a vertical cross-sectional view, FIG. 3 is a vertical cross-sectional view when the dust collector is lowered, and FIG. 4 is a dust trap. FIG. 5 is a side view of the dust collection body, FIG. 6 is a guide passage body, FIG. 7 is a detailed view of the dust collection body, and FIG. FIG. 9 is a main part configuration diagram, and FIG. 10 is a block diagram.

In an air conditioner 2 having an indoor unit composed of a wide, substantially rectangular parallelepiped main body case 1 attached to an indoor wall or the like, the main body case 1 has a wide suction port 3 on its upper surface side and a lower suction surface. The wide outlet 4 and the front surface are provided with a light receiving portion 33 for receiving an instruction from a remote control body 5 to be described later, a display portion 6 having an energizing lamp, etc., and a bent portion at the joint between the front portion and the upper surface portion. The part is formed.
The suction port 3 and the blowout port 4 are communicated with each other through a ventilation air passage 7, and a guide passage body 9 that movably supports a dust collector 8, which will be described later, at a position close to the suction port 3 on the upstream side of the ventilation air passage 7. The main body case 1 is formed so as to face both side portions. The guide passage body 9 extends from the upper surface portion to the lower end portion of the main body case 1 so as to follow the longitudinal cross-sectional shape of the main body case 1, and has an upper straight portion 29 and a lower straight portion 30. 28 is provided and is formed in a substantially L-shape, and its cross-sectional shape is a U-shape and is formed by the movable groove 31 and the support wall 32. The lower end is in contact with a descending groove 10 formed in the lower front portion of the main body case 1.

A heat exchanger 11 is stored downstream of the dust collector 8, and a blower 12 is housed in the vicinity of the outlet 4 downstream thereof. The main body case 1 also houses a control unit 27 that controls various electrical components and sensors.
The dust collector 8 is an ultra-thin filter 13 made of a net having a large number of pores, and is formed and held integrally with a frame body 14 and formed into a flat shape. Has been.
Support portions 26 are formed on both side surfaces, and the support portions 26 are movably supported by the support wall 32 and the movable groove 31 of the ventilation air passage 7. A linear drive gear 15 is formed in the vicinity of one support portion 26, and a linear guide body joint portion 16 is also formed in the central portion. Furthermore, a handle portion 17 that facilitates attachment to and removal from the guide passage body 9 is formed at the lower end portion. The dust collector 8 can be matched with the guide passage body 9 having the bent portion 28 by being configured to be bent with a soft member.

  The drive body 18 includes a motor 19 and a speed reduction mechanism 20, and the speed reduction mechanism 20 is fitted with the drive gear 15 so that the dust collecting body 8 reciprocates at least once in the downward and upward movements in the guide passage body 9. It is controlled to rotate forward and backward by a control body (not shown).

The dust collector 21 contacts over the entire width of the upstream surface of the dust collector 8 formed in a wide width, and the trapping brush 22 that collects dust while rotating the dust collector 21 drops the captured dust into the dust chamber 24. It is comprised from the removal brush 23, the capture brush 22 which collects dust, and the dust collection chamber 24 formed separably. The dust collection chamber 24 is structured to be detachable from a part of the main body case 1 so that it can be easily taken out from a takeout port (not shown). At this time, the extraction port is formed with a small-diameter hole, and an opening / closing lid (not shown) is formed by inserting a suction pipe of a vacuum cleaner from the outside and forming an opening / closing lid (not shown) in the dust collecting chamber 24. ) May be opened to suck dust.
The capture brush 22 is positioned in the bent portion or in the vicinity of the dust collector 8 so that when the dust collector 8 is moved, a centrifugal force acts on the front side of the main body case 1 to be deformed. In addition to receiving and preventing deformation, dust adhering to the outer surface of the dust collector 8 is also pressed against the capture brush 22, and dust collection is performed reliably.

The guide body 25 is rotatably disposed at the center of the width of the capture brush 22 and is joined to the guide body joint 16 formed on the downstream surface side of the dust collector 8 to prevent the dust collector 8 from being deformed. . In particular, since the dust collector 8 is provided in a position facing the capture brush 22, the dust collector 8 can be supported in a sandwich shape, and deformation is reliably prevented.
Further, by making the guide body 25 in contact with the dust collector 8 rotatable, the contact resistance thereof is reduced, and the vertical movement of the dust collector 8 by the drive body 18 can be performed more smoothly and driven. This is useful for reducing the load on the body 18.
The remote control body 5 has operation buttons for operating on / off of driving, a timer, the intensity of air flow, and the like, and transmits the information.

  The dust capturing and discarding operations in this embodiment are performed as follows.

  By operating the remote control body 5 toward the display unit 6 provided on the front surface of the main body case 1, the blower 12 starts to rotate, and the outside air containing dust floating in the room enters through the suction port 3, and the dust is It is collected by the dust collector 8 and becomes clean air, and passes through the heat exchanger 11. At this time, the clean air becomes a clean air that stores predetermined cooling or heating energy in each mode of cooling or heating, passes through the blower 12, and blows out into the room through the blowout port 4 to achieve a comfortable room temperature.

  When the operation is stopped for a predetermined time or consciously, the driving body 18 starts to operate according to a program previously controlled by the control unit 27. The dust collector 8 connected to the drive body 18 starts to descend from above at a predetermined speed in the guide passage body 9. The support portion 26 of the dust collector 8 having a bent portion is supported by the guide passage body 9, but since the central portion is free, it is easily deformed due to its centrifugal force and soft member. Since the capture brush 22 is disposed on the upstream side, not only the deformation is prevented, but also dust is reliably captured.

  Further, since the capture brush 22 is formed to be rotatable, its contact resistance does not greatly hinder the movement of the guide passage body 9 of the dust collector 8. Further, a guide body joint portion 16 is formed at the lateral center of the dust collector 8, and a rotatable guide body 25 joined to the joint portion is provided. In order to support it in the form of a sandwich, the dust collector 8 is reliably prevented from being deformed.

  The dust collector 8 starts to descend from above in the guide passage body 9, and the capture brush 22 in contact with the dust collector 8 rotates to remove the dust adhering to the surface of the dust collector 8. 22 is scraped off and spills into the dust collecting chamber 24. At the same time, dust left on the capture brush 22 is also removed by the comb-like removal brush 23 and spills into the dust collection chamber 24. The dust collection chamber 24 is taken out from the take-out port of the main body case 1, and after removing the lower portion of the dust collection chamber 24, the dust is thrown into the trash can. At this time, the suction pipe of the vacuum cleaner may be inserted from the outside to form an opening / closing lid (not shown) in the dust collection chamber 24, so that the opening / closing lid is opened to suck the dust.

  In addition, although the capture brush 22 is formed to be rotatable, the presence / absence of a rotation drive body (not shown) of the capture brush 22 and the rotation direction can be set in a timely manner other than the above-described configuration. For example, there is a rotary drive (not shown), and when the dust collector 8 is lowered, the capture brush 22 does not rotate, and when a part of the dust collector 8 is exposed from the descending groove 10, the dust collector 8 is temporarily stopped. A configuration in which dust captured by the capture brush 22 is removed by the removal brush 23 by rotating the capture brush 22 with a rotary drive (not shown) can also be employed.

Further, at least when the upper part of the lowered dust collector 8 has passed through the capture brush 22, the lower end portion of the dust collector 8 is exposed from the lowering groove 10 formed on the front surface of the main body case 1, so that the user In addition, the cleaning of the dust collector 8 can be visually recognized. When the dust collector 8 is exposed, its position is recognized by a sensor or the like (not shown) so that the driving body 18 is reversed, the dust collector 8 starts to rise, and the operation is stopped at a predetermined position. Etc. (not shown). For this reason, when the blower is operated, the dust collector 8 is always free of dust and is clean. These operations may be programmed in the control unit 27 so as to be performed before the start of the blower operation.
Also, by setting a program so that the handle 17 formed at the lower part of the frame 14 of the dust collector 8 stops at the position exposed from the descending groove 10, the handle 17 can be easily pulled out during maintenance. The collector 8 can be attached and detached.

  As described above, the air conditioner according to the present invention has a thin main body, can be easily cleaned, and can be easily maintained while maintaining the conventional dust scraping performance. It can be applied not only to various air conditioners, but also to various devices having filters such as air purifiers and ventilators.
