And a filter body for collecting dust comprising a frame body that holds the outer periphery of the filter, and an air conditioner that sucks outside air containing floating dust in the room from the suction port and discharges it from the exhaust port A rotating cleaning body that is in sliding contact with the upstream surface of the filter body and collects oil is provided, and the rotating cleaning body is formed in a disc shape and a cloth, and is formed on the outer periphery of the shaft body. Since the cloth has a large number of gaps between a plurality of fibers forming the cloth, the rotary cleaning body having the cleaning piece made of the cloth is used as the filter body. Sliding on the upstream surface It allows the oil adhering to the filter can be reliably attracted dust removal operation from the filter body after becomes very easy. In particular, since the cleaning pieces are laminated, the amount of oil adsorbed is increased and can be used longer. Furthermore, since the outer peripheral edge of the disc-shaped cleaning piece is in sliding contact with the filter body, the oil adsorption force can be improved. In addition, when a normal rotating brush for dust removal is separately provided, dust removal by the dust remover is surely performed, and the cleaning efficiency of the filter body is improved even in harsh environments such as a kitchen with a lot of oil. It is possible to provide an air conditioner that can be used for a long time without loss.

  In the third invention, in particular, a predetermined interval is provided between the adjacent cleaning pieces of the second invention, and the cleaning piece is inclined with respect to the major axis direction of the shaft body. In this case, since the sliding contact resistance between the rotary cleaning body and the filter is reduced by inclining and laminating, the drive body that drives the rotary cleaning body can be reduced in size.

  1 to 5, a front panel 3 having a plurality of suction ports 2 and having an upper end rotatably attached to the main body 1 is attached to the front portion of the main body 1 of the air conditioner according to the present embodiment. An exhaust port 4 is provided at the lower portion of the main body 1, and the suction port 2 and the exhaust port 4 are communicated with each other in a passage air passage 5 that guides indoor air containing floating dust from the suction port 2 to the exhaust port 4. From the front panel 3 side, the filter body 6 that captures dust contained in the indoor air flowing in from the suction port 2, the indoor heat exchanger 7 that exchanges heat from the flowing indoor air, and the suction port 2 A blower 8 is provided for sucking indoor air and blowing out the air heat-exchanged by the indoor heat exchanger 7 from the exhaust port 4.

  A filter body passage port 9 through which the filter body 6 appears and disappears is provided on the lower surface of the main body 1. On the upstream side of the filter body 6, an oil content adsorbing body 11 that adsorbs oil adhering to the filter body 6, and a dust removing body 12 that is located directly below the oil content adsorbing body 11 and that removes dust captured by the filter body 6, A dust storage body 13 is provided below the dust removal body 12 for storing the dust removed by the dust removal body 12 and falling. Although not particularly illustrated, an opening for taking in and out the dust container 13 is provided on the side surface of the main body 1.

  Reference numeral 14 denotes a first driving body that moves the filter body 6 obliquely upward and downward while guiding the filter body holding groove 15 provided in the main body 1 when the filter body 6 is cleaned. When the filter body 6 is moved diagonally downward by driving the filter body 6, the filter body 6 jumps outward from the filter body passage port 9, and conversely, when the filter body 6 is moved obliquely upward, the filter body 6 becomes the main body. It is designed to be stored in 1. Reference numeral 16 denotes a control body that controls electric components such as the blower 8 and the first driving body 14.

  The filter body 6 includes a filter 6a made of a sheet-like filter material for collecting dust, and a frame body 6b that holds the outer periphery of the filter 6a. A rack gear 6c is provided on one side of the rear surface of the frame body 6b. , Extending vertically and integrally.

  The first drive body 14 includes a first motor 17 and a first drive gear 18 that is fixed to the rotating shaft 17a and meshes with a rack gear 6c provided on the frame body 6b.

  In FIG. 3, an oil adsorbent 11 includes a base 11a whose both ends are detachably supported in the main body 1 and a cloth such as a non-woven fabric which is substantially blade-shaped and is sandwiched by the base 11a on one side and made of a plurality of fibers. As shown in FIG. 1, the oil adsorbing body 11 is arranged such that the cleaning piece 11 b is obliquely pressed against the upstream surface of the filter body 6.

  The dust removing body 12 has a shaft body 12a, one end of which is rotatably supported by a bearing portion 1a provided on the main body 1 and the other end connected to a second driving body 20 such as a geared motor, and a large number of small diameters. The brush 12b is made of fiber and is attached to the outer periphery of the shaft body 12a in a radial manner and is in contact with the upstream surface of the filter body 6 to remove dust attached to the filter 6a. The width of the brush 12b is set to be approximately equal to the entire width of the filter 6a of the filter body 6. The attachment of the brush 12b to the outer periphery of the shaft body 12a may be fixed by a method such as adhesion, welding, and flocking, or may be detachably attached.

  With the above configuration, the filter body 6 is driven by driving the second driving body 20 connected to one end of the shaft body 12a of the dust removing body 12 and rotating the dust removing body 12 clockwise as shown in FIG. It is possible to efficiently scrape off dust adhering to the upstream surface.

  The length of the dust container 13 that receives the dust removed by the dust remover 12 in the left-right direction is substantially the same as the length over the entire width of the filter body 6. An opening 13a facing the 12 brushes 12b is formed, and a comb tooth 21 whose tip bites into the brush 12b is provided in a part of the dust container 13 in parallel with the brush 12b.

  The operation and action of the air conditioner in the present embodiment configured as described above are as follows.

  In addition, since the operation | movement at the time of the cooling / heating operation of the air conditioner in a present Example is the same as that of the conventional air conditioner, the description is abbreviate | omitted and especially the operation | movement at the time of the cleaning operation of the filter body 6 is demonstrated.

  At the start of the cleaning operation, the tip of the cleaning piece 11 b of the oil adsorbent 11 is located at the lower end of the filter 6 a of the filter body 6. Next, when a filter cleaning switch (not shown) provided on the main body 1 or a remote control (not shown) for remotely operating the main body 1 is operated, the second driving body 20 and the first driving body 14 are operated. Starts. Then, the filter body 6 starts moving slowly and obliquely downward by the operation of the first drive body 14. During this time, the oil adhering to the filter 6a is first adsorbed by the cleaning piece 11b of the oil adsorbing body 11, and the dust remaining on the upstream surface of the filter 6a is rotationally driven by the second driving body 20. The dust 12 is scraped off by the brush 12b, and the dust falls and accumulates in the dust container 13.

  As described above, in this embodiment, the oil adhering to the filter 6a is first adsorbed by the oil adsorbing body 11 from the lower end to the upper end of the filter body 6, and then the dust remaining in the dust removing body 12 is removed. It is like that.

  In the present embodiment, during the cleaning operation of the filter body 6, the peripheral speed of the outer periphery of the brush 12 b is set to be larger than the descending speed of the filter body 6. This reliably removes dust attached to the filter body 6 and prevents an excessive load on the filter body 6, that is, an excessive load on the first drive body 14.

  During the above operation, dust may remain attached to the brush 12b. However, since the tips are sequentially removed by the comb teeth 21 biting into the brush 12b, the dust removal performance may gradually deteriorate. No.

  When the filter body 6 is completely lowered by the operation of the first driving body 14 and the cleaning of the filter body 6 is completed, the first driving body 14 automatically reverses and the filter body 6 is held by the filter body. It rises while being guided by the groove 15 and returns to the initial storage position.

  If the dust removing body 12 is rotated by the second drive body 20 while the filter body 6 is raised, the filter body 6 can be cleaned more reliably. Alternatively, while the filter body 6 is raised, the mechanical connection between the dust removing body 12 and the second driving body 20 is released using a clutch mechanism (not shown) or the like, and the dust removing body 12 can freely rotate. If it does in this way, the load added to the filter body 6, ie, the load added to the 1st drive body 14, will come to reduce significantly, and the 1st drive body 14 can also be reduced in size.

  When the filter body 6 is cleaned several times as described above and the inside of the dust storage body 13 is filled with dust, the dust storage is performed from an opening (not shown) provided on the side surface of the main body 1. The body 13 may be taken out and the dust inside may be discarded.

  Although the cost is high, a suction device (not shown) is connected to the dust container 13 to detect that the dust container 13 is filled with dust periodically or using optical means. In this case, if the suction device is operated and discharged to the outside, an air conditioner that does not require time and is easy to maintain can be provided.

  Further, if the filter body 6 is cleaned several times, the oil adsorbing capacity of the oil adsorbing body 11 gradually decreases, and accordingly, the dust adhering to the filter 6a becomes difficult to be removed, and the dust removing body 12 removes the dust. Since the performance deteriorates, it is assumed that the oil adsorbing state is appropriately checked, and if necessary, the oil adsorbing body 11 is removed from the main body 1 and replaced with a new one.

  As described above, according to the air conditioner of the present embodiment, since the fabric forming the cleaning piece 11b of the oil adsorbent 11 has a large number of extremely fine bubbles, the oil adhering to the filter 6a is surely secured. Can be absorbed. As a result, dust removal by the dust remover 12 can be performed reliably, and the air conditioner can be used for a long time without impairing the cleaning efficiency of the filter 6a even in a harsh environment such as a kitchen with a lot of oil. Can be provided.

  Moreover, as shown in FIG. 6, if the slit 11c or the unevenness 11d is formed in the cleaning piece 11b of the oil adsorbing body 11, the surface area increases, so the amount of oil adsorbing increases and the oil adsorbing body 11 is used longer. You can also

  FIG. 7 is a perspective view of a rotary cleaning body of an air conditioner and a perspective view of a cleaning piece in the second embodiment of the present invention. In addition, about the same part as the air conditioner in the said 1st Example, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the first embodiment, the oil adhering to the filter 6a is adsorbed by the cleaning piece 11b of the fixed oil adsorbing body 11. However, in this embodiment, the cleaning piece is provided on the outer periphery as the oil adsorbing body. The oil component adhering to the filter 6a is adsorbed using a rotary cleaning body that is provided and rotated.

  In FIG. 7, reference numeral 23 denotes a rotary cleaning body of the air conditioner in the present embodiment, one end of which is rotatably supported by the main body 1 of the air conditioner, and the third drive body 24 is connected to the other end. A rod-shaped shaft body 25, a disk-shaped, a plurality of cleaning pieces 26 mounted on the shaft body 25 and stacked, a disk-shaped plate 27 sandwiching the stacked cleaning pieces 26 from both sides, and a plate 27 The stopper 28 is fixed so as to be pressed inward.

  A rib 25 a is extended in the longitudinal direction of the outer periphery of the shaft body 25 to prevent the cleaning piece 26 from rotating. The cleaning piece 26 is formed of a fabric such as a nonwoven fabric made of a plurality of fibers, and has a recess 26a engaging with the rib 25a in a part of the periphery at the center, and a hole for inserting the shaft body 25 therein. 26b is formed, and slits 26c are formed in a substantially radial manner in the vicinity of the outer periphery.

  Next, although it does not show in particular about the manufacturing method of the nonwoven fabric which forms the cleaning piece 26, some examples are described below.

  In the first method, a plurality of fibers are accumulated in a flat plate shape to form a cloth-like body, a plurality of the cloth-like bodies are overlapped, and then a special needle is pierced to entangle in three dimensions. To obtain a non-woven fabric. The manufacturing method is generally called needle punching. The cloth-like body is called a web. The obtained nonwoven fabric is impregnated in a polyurethane solution, and the nonwoven fabric is filled with polyurethane. Next, the non-woven fabric filled with polyurethane is immersed in water, carbon dioxide is injected into the water, and carbonic acid foaming is performed, thereby forming a flat plate-like two-layer made of non-woven fabric and porous polyurethane having extremely fine bubbles. A heavy structure is formed. For the fibers forming the nonwoven fabric, polyester fibers, nylon fibers, spandex fibers also called urethane elastic yarns, etc. are used alone or in combination.

  In the second method, a plurality of fibers are accumulated in a flat plate shape to form a web that becomes a cloth-like body, and a nonwoven fabric entangled three-dimensionally by needle punching is obtained. To the obtained nonwoven fabric, a polymer elastic body blended with a crosslinking agent is attached using a method such as spraying, dipping, or impregnation, and the fibers constituting the nonwoven fabric are bonded together by heating, The nonwoven fabric obtained by this manufacturing method is generally called a chemical bond method nonwoven fabric.

  For the fibers forming the nonwoven fabric, natural fibers such as cotton, rayon and cellulose, and synthetic resin fibers such as polyester, nylon and acrylic are used alone or in combination. In addition, nitrile rubber, acrylic rubber, styrene rubber, urethane rubber, acrylic resin, urethane resin and the like are used alone or in combination for the polymer elastic body. The crosslinking agent is blended for the purpose of forming a bridge structure between the molecules of the polymer elastic body and imparting further excellent elasticity to the polymer elastic body. Trimethylolmelamine, hexamethylol Melamine resins such as melamine, isocyanate resins such as blocked isocyanate, and epoxy resins such as aliphatic epoxy can be used alone or in combination.

In the third method, a thermoplastic resin such as a polyamide resin, a polyester resin, a polyethylene resin, or a polypropylene resin is melt-spun, and 1 is applied to the obtained thermoplastic resin fiber.
The fibers are intertwined by jetting a high-pressure water stream of about 00 to 150 kgf. Next, a non-woven fabric obtained by the above production method is formed by attaching a polymer elastic body containing a crosslinking agent to a fiber using a method such as spraying, dipping, or impregnation, and heating to form a non-woven fabric. It is generally called a hydroentangled nonwoven fabric.

  The above-described method for producing a nonwoven fabric is a representative example. Besides the above, for example, a hot-melt synthetic resin is continuously spun to form a fiber, and the fiber is stretched and collected on a collection net. The spunbond method, in which fibers are bonded by pressurizing with a hot roll to form a non-woven fabric, and when hot-melt synthetic resin is discharged from the spinning port, the fibers heated on the collection net are spun with high-temperature air. Melt blow method for forming a nonwoven fabric by bonding, dissolving a synthetic resin in a low boiling point solvent such as methylene chloride, chlorofluorocarbon, heating from a spinning port, spinning fibers in a pressurized state, and volatilizing the low boiling point solvent at the same time, The fiber is collected on a collection net and pressed by a hot roll to bond the fibers to form a non-woven fabric. The flash spinning method melts multiple synthetic resins with different melting points and spins the synthetic resin with the higher melting point. Shape the fiber And, it may also be prepared by the fibers is adhered fiber bonding method to form a non-woven fabric and thermal bond method or the like synthetic resin having a lower molten melting point as a binder.

  When the nonwoven fabric is used for the cleaning piece 26 laminated as described above, the cleaning piece 26 is resistant to repeated contact of the surface to be cleaned and the fibers are not easily frayed. Compared with the case where it uses for, it leads to the improvement of durability of the rotary cleaning body 23. FIG.

  Next, the manufacturing method of the rotary cleaning body 23 in a present Example is described below.

  First, a slit 26c is inserted into a fabric sheet (not shown) made of a plurality of fibers using a Thomson type or a laser cutter. Next, the substantially annular cleaning piece 26 having the concave portion 26a, the hole 26b, and the side edge portion 26d is punched out using the same Thomson type or laser cutter.

  Next, a plurality of cleaning pieces 26 are overlapped so that the recesses 26a are in the same position, the holes 26b are passed through the shaft body 25, and are stacked on the outer periphery of the shaft body 25. The plates 27 are attached to both sides of the shaft 26, and the stacked cleaning pieces 26 are compressed to a predetermined length from the longitudinal direction of the shaft body 25 with a press machine, and then fixed with a stopper 28. Next, by letting it stand for a predetermined time, the internal stress of the plurality of cleaning pieces 26 overlapped is made uniform, and the side edge portion 16 is cut and polished to finish.

  As described above, according to the present embodiment, since the cleaning pieces 26 are laminated, the amount of oil adsorbed increases and can be used for a longer time. Further, since the side edge portion 26d of the disc-shaped cleaning piece 26 is in sliding contact with the filter body 6, the oil adsorption force can be improved. As a result, dust removal by the dust remover 12 can be performed more reliably, and air that can be used for a long time without impairing the cleaning efficiency of the filter body 6 even in a harsh environment such as a kitchen with a lot of oil. A harmonic machine can be provided.

  In the above-described embodiment, the cleaning pieces 26 are stacked on the shaft 25 so as to be in close contact with each other. However, as shown in FIG. A predetermined interval may be secured between the adjacent cleaning pieces 26 by interposing a curler 30 having a smaller diameter. In this way, the portion of the cleaning piece 26 in the outer diameter direction from the curler 30 is in a free state without being compressed, so it swells more than the compressed one, and the gap between the fibers becomes larger, absorbing oil. The capacity can also be increased.

  Further, as shown in FIG. 8B, each cleaning piece 26 is formed by punching a sheet-like member so as to have a cross-sectional shape obtained by obliquely cutting a cylindrical body, and further, adjacent cleaning pieces 26. A curler 31 having both ends cut obliquely and in parallel is provided to provide a predetermined interval between adjacent cleaning pieces 26 and the cleaning pieces 26 are inclined with respect to the major axis direction of the shaft body 25. By doing so, the sliding contact resistance between the rotary cleaning body 23 and the filter 6a is reduced, so that the third drive body 24 that drives the rotary cleaning body 23 can be downsized.

  In addition, a monofilament-like fiber is adopted for the nonwoven fabric used as the material of the cleaning piece 26, and the surface of the monofilament-like fiber has, for example, a roughly textured shape, a generally slit shape, a roughly scratched wound shape, a generally scratched wound shape, etc. If an uneven portion (not shown) is formed, the oil can be scraped off by the convex portion and can be collected by the concave portion. Moreover, as a material, highly lipophilic fibers such as polypropylene fibers are suitable.

  Moreover, in the said 1st, 2nd Example, although the cleaning pieces 11b and 26 which adsorb | suck an oil component were formed with fabrics, such as a nonwoven fabric which consists of a plurality of fibers, a nonwoven fabric and ultrafine as described below A fabric formed of a porous polyurethane double structure having various bubbles may be used.

  In FIG. 9, the cleaning pieces 11 b and 26 are formed of a double structure composed of a nonwoven fabric 33 and a base portion 34, and a gap portion 35 is formed between the nonwoven fabric 33 and the base portion 34.

  The nonwoven fabric 33 is formed of a plurality of ultrafine fibers 33a, and the material thereof is at least one kind of materials selected from polyamide fiber, polyester, polyethylene fiber, polypropylene fiber, and urethane rubber fiber, or a plurality of materials. The material which combines is used. The base 34 is formed of a porous structure having extremely fine bubbles 36, and polyurethane is used as the material.

  When a polyamide fiber typified by nylon is used as the material of the nonwoven fabric 33, the polyamide fiber has high wear resistance, heat resistance, high chemical resistance from weak acid to strong alkali, and high water absorption. The cleaning pieces 12b and 26 can have the characteristics such as these.

  In addition, when polyester is used, the roll part should have characteristics such as heat resistance, high chemical resistance from strong acid to weak alkali, low water absorption, low price, etc., possessed by polyester. Can do. When polyethylene fiber is used, the roll part can have characteristics such as high chemical resistance in acid and alkali, polyethylene water absorption of 0%, and low price.

  Further, when polypropylene fibers are used, the cleaning pieces 12b and 26 can have characteristics such as water absorption of 0%, low price, and light weight, which the polypropylene fibers have.

  Also, when urethane rubber fibers, also called urethane elastic yarns, are used, the cleaning pieces 12b and 26 may have characteristics such as the lipophilicity and elasticity that the urethane rubber fibers have. I can do it.

  Next, the manufacturing procedure of the double structure which comprises the cleaning pieces 12b and 26 is demonstrated.

  First, a main component and a subcomponent are mixed and spun to create a fiber, and then a special needle (not shown) is pierced and the fiber is knitted three-dimensionally. As described above, the manufacturing method of three-dimensional knitting is generally called needle punching. Next, after the fiber is impregnated with urethane and solidified to form a porous polyurethane having extremely fine bubbles, the subcomponent is dissolved and removed.

  As described above, the following effects can be obtained by using the fabric formed of the nonwoven fabric and the porous polyurethane dual structure having extremely fine bubbles for the cleaning pieces 11b and 26.

  Since the polyurethane base 34 has high wear resistance, the cleaning pieces 11b and 26 having excellent durability can be manufactured. Moreover, since the base part 34 has very fine bubbles, the cleaning pieces 11b and 26 can be lightened, and the impact applied to the cleaning pieces 11b and 26 can be absorbed.

  Since the cleaning pieces 11b and 26 are formed of a double structure composed of the nonwoven fabric 33 and the base 34, a gap 35 is formed between the nonwoven fabric 33 and the base 34, and the base 34 is extremely fine. The cleaning pieces 11b and 26 can be flexibly brought into contact with the surface to be cleaned because they are made of porous polyurethane having various bubbles. Further, since the base portion 34 is made of porous polyurethane, the surface to be cleaned is not damaged.

  Further, if a non-woven fabric having lipophilicity is used for the cleaning pieces 11b and 26, and the tip cross-sectional shape of the cleaning pieces 11b and 26 is substantially arcuate, moisture such as dirt, oil, and dust attached to the filter 6a. In addition to adsorbing various types of dirt, such as dust, in the gaps between the fibers woven into the nonwoven fabric, in particular, because it can strongly adsorb oil, washing, cleaning and polishing at the same time, It can also be accurate.

  In the first and second embodiments, the dust body 12 is provided to enable the filter body 6 to be automatically cleaned, and the filter body 6 is driven up and down by the first drive body 14. However, the present invention is not a condition for this, and when the user cleans the filter body 6, the filter body passes through the filter body passage port 9 provided in the main body 1 of the air conditioner. 6 may be pulled out. Also in this case, when the filter body 6 is pulled out, the oil adhering body 11 absorbs the oil adhering to the filter body 6, so that the user can hold the filter body 6 with a hand-held brush or a vacuum cleaner. Easy to clean.

  Moreover, in the said Example, although the rib 25a was provided in the shaft body 25 and the recessed part 26a fitted to the rib 25a was provided in the cleaning piece 26, the rotation prevention between both was performed, but FIG.8 (d). As shown in FIG. 3, the shaft body 105 may be provided with a groove portion 101, and the cleaning piece 106 may be provided with a convex portion 100 fitted to the groove portion 101 to prevent rotation between the two (the shaft body 105). And the cleaning piece 106 is the same as each of the shaft body 25 and the cleaning piece 26 in the first and second embodiments except for the anti-rotation configuration.

However, in this embodiment, the filter body 6 is fixed at a fixed position, and the rotary cleaning body 23 and the dust removing body 12 are moved up and down along the upstream surface of the filter body 6 to clean the entire area of the filter body 6. It is what I did.

  In FIG. 10, a cleaning unit 39 is provided on the upstream side of the filter body 6 of the air conditioner in the present embodiment so as to be movable up and down along a guide rail 38 provided in the main body 1.

  In the upper part of the cleaning unit 39, there are a rotary cleaning body 23, a third drive body 24 that rotationally drives the rotary cleaning body 23, a dust removal body 12 disposed below the rotary cleaning body 23, and a dust removal body 12. The second driving body 20 that is rotationally driven, the dust storage body 40 that stores the dust removed by the dust removal body 12 and falling, and the cover 41 that covers the rotary cleaning body 23 and the dust removal body 12 are configured. Although not particularly illustrated, the air conditioner main body 1 is provided with a fourth drive body that moves the cleaning unit 39 up and down.

  The cleaning operation of the filter body 6 of the air conditioner in the present embodiment configured as described above is as follows.

  Usually, the cleaning unit 39 is held at a position where the cleaning piece 26 of the rotary cleaning body 23 provided therein is in contact with the lower end of the filter 6a of the filter body 6 (hereinafter referred to as “bottom dead center”). When a cleaning switch (not shown) is operated to clean the filter body 6, the operation of the second drive body 20, the third drive body 24, and the fourth drive body (not shown) starts, and the dust removing body 12 and the rotary cleaning body 23 gradually move upward while rotating clockwise. In the meantime, the oil adhering to the filter 6a is absorbed by the rotary cleaning body 23, and then dust remaining on the filter 6a is scraped off by the brush 12b, falls into the dust container 40, and gradually accumulates. I will do it. The dust that adheres to the brush 12 b and does not fall naturally falls on the comb teeth 40 a provided in the dust container 40 and falls into the dust container 40.

  When the cleaning unit 39 reaches a position where the brush 12b of the dust remover 12 is in contact with the upper end of the filter 6a (hereinafter referred to as “top dead center”), the fourth drive is automatically performed to prepare for the next cleaning operation. The body is reversely driven, and after the cleaning unit 39 is moved to the original bottom dead center, it automatically stops.

  When the dust container 40 is filled with dust, the dust container 40 can be easily removed by removing it from the cover 41.

  As described above, according to the present embodiment, since the filter body 6 is fixed and the cleaning unit 39 is moved up and down, the filter body 6 is moved from the bottom of the main body 1 during the cleaning operation of the filter body 6. It is possible to provide an air conditioner that does not pop out and is excellent in design.

  In the above embodiment, the second driving body 20 and the third driving body 24 are provided separately, but both the dust removing body 12 and the rotary cleaning body 23 are driven by only one of the driving bodies. By doing so, it is possible to reduce the number of driving bodies by one and to reduce the cost and weight.
