- the refrigerant is compressed by the compressor 9 and is sent toward the outdoor heat-exchanger 11 at high temperature and pressure.
- the refrigerant radiates heat to the outdoor air, condenses, and liquefies.
- the liquefied refrigerant is depressurized as it passes through an expansion valve and flows into the indoor heat-exchanger 23.
- the refrigerant draws heat from the indoor air and vaporizes.
- the vaporized refrigerant flows into the compressor 9 again and repeats the above-described cycle.
- the refrigerant is compressed by the compressor 9 and is sent to the indoor heat-exchanger 23.
- the refrigerant radiates heat to the indoor air, condenses, and liquefies.
- the liquefied refrigerant is depressurized as it passes through the expansion valve and flows into the outdoor heat-exchanger 11.
- the refrigerant draws heat from the outdoor heat-exchanger 11 and vaporizes.
- the vaporized refrigerant flows into the compressor 9 again and repeats the above-described cycle.
- the indoor air flows from the air inlet 17 into the chassis 15 as the indoor fan 21 is rotated by the fan motor 25.
- the indoor air flowing into the chassis 15 passes through the air filter 31, and the dust included in this indoor air is collected at the air filter 31.
- the indoor air that passes through the air filter 31 passes through the bellmouth 27 and is taken in by the indoor fan 21.
- the indoor air taken in by the indoor fan 21 is sent outwards in the radial direction of the indoor fan 21 and passes through the indoor heat-exchanger 23.
- a cooling mode the indoor air is cooled when it passes through the indoor heat-exchanger 23, and its heat is absorbed by the refrigerant.
- a heating mode the indoor air is heated when it passes through the indoor heat-exchanger 23 and receives heat from the refrigerant.
- the indoor air that passes through the indoor heat-exchanger 23 flows out from the air outlets 29 into the room.
- the driving screw 45 is rotationally driven by the driving motor 47.
- the rotation of the driving screw 45 is converted into a reciprocating movement by the split nut 43.
- the reciprocating movement of the split nut 43 is transmitted to the dust box 37 that is engaged with the split nut 43. Since the brush unit 35 reciprocates together with the dust box 37, dust attached to the air filter 31 is scraped off and collected in the dust box 37.
- the dust removal as described above, can be suitably carried out by driving the driving motor 47 by detecting clogging of the air filter 31, the total operating time of the indoor unit 3, and/or shut-off of the indoor unit 3.
- the dust collected in the dust box 37 causes the partition 49 to move toward the detecting unit 51.
- the linking unit 55 upon receiving the movement of the partition 49, protrudes upward by a predetermined amount.
- the detecting unit 51 detects the amount of dust collected by detecting the protrusion of the linking unit 55 and, when a predetermined amount of dust is collected, notifies this in a predetermined manner, as described above.
- the dust in the dust box 37 is removed.
- the rotation of the lifting motors 59 is controlled by operating a remote controller, and the wires 63 wound around the sprawls 65 are let out.
- the pulleys 61 turn and the air inlet grill 19 is lowered from the chassis 15 while maintaining a substantially horizontal orientation.
- the air filter 31, the brush unit 35, and the dust box 37 disposed on the air inlet grill 19 are lowered together with the air inlet grill 19.
- the operator can remove the dust from the dust box 37. If necessary, any dust remaining on the air filter 31 can be directly removed.
- the wires 63 are wound around the sprawls 65 by driving the lifting motors 59. As the wires 63 are wound up, the air inlet grill 19 moves upward while maintaining a substantially horizontal orientation and is finally stored inside the chassis 15.
- the side surfaces of the dust box 37 are inclined away from each other so that they are furthest apart at the upper edge of the dust box 37. Therefore, the dust box 37 and the split nut 43 are engaged by adjusting their relative positions against the inclined surfaces.
- dust attached to the air filter 31 can be removed by the brush unit 35. Therefore, when cleaning the air filter 31, the air filter 31 does not have to be removed from the chassis 15. In this way, the operator does not have to climb up high, and less effort is required for carrying out maintenance of the air filter 31.
- the dust removed by the brush unit 35 is collected in the dust box 37.
- the raising units 57 allow the chassis 15 to be lowered together with the dust box 37. Therefore, the operator does not have to climb up high to remove the dust box 37, which holds the dust, from the chassis 15. In this way, less effort is required for carrying out maintenance of the air filter 31.
- the dust box 37 Since the removed dust can be collected in the dust box 37, the dust box 37 does not have to be removed each time the air filter 31 is cleaned. In other words, removal of the dust from the dust box 37 only has to be carried out every several times that cleaning of the air filter 31 is carried out. In this way, less effort is required for carrying out maintenance of the air filter 31.
- the brush unit 35 and the air filter 31 can be moved relative to each other by the driving unit 41 to remove dust attached to the air filter 31.
- the driving motor 47 and other components are disposed on the chassis 15, the load applied to the raising units 57 when lifting and lowering the dust box 37 can be reduced.
- the air filter 31 is supported so that it can be raised to or lowered from the chassis 15 by the raising units 57, the operator can directly and easily clean the air filter 31. Moreover, the operator can clean areas in the air filter 31 where the brush unit 35 cannot reach.
- one driving unit 41 may be disposed on one side on the frame of the air inlet grill 19, or a pair of driving units may be disposed on opposing sides on the frame of the air inlet grill 19.
- the number and position of the driving unit 41 are not limited.

The movement of the split nut 43 is transmitted to the dust box 137 engaged with the split nut 43, and the dust box 137 moves together with the brush unit 135. By moving in this way, the brush unit 135 scrapes off the dust attached to the air filter 31. The scraped off dust is collected in the dust box 137.
- the brush unit 135 and the dust box 137 move to an area at the end of the driving screw 45 where the air filter 31 is not disposed.

- Fig. 33 is a cross-sectional view illustrating the structure of the dust-amount detecting unit illustrated in Fig. 32 .
- a dust-amount detecting unit 715 includes covers 717 configured to cover the openings of the cleaning unit 633, a fan 719 configured to take in air, and a flow sensor (sensor) 721 configured to detect the flow rate of the air taken in by the fan 719.
- the covers 717 are disposed opposite to the outer edges in the movement directions (vertical direction in Fig. 32 ) of the cleaning unit 633 of the air filter 631. As shown in Fig. 33 , the covers 717 are disposed on substantially the same plane as the air filter 631.
- the fan 719 and the flow sensor 721 are disposed on the upper surface (upper side of Fig. 33 ) of one of the covers 717.
- the fan 719 is rotated to suck out air from the inside of the cleaning unit 633 through channels (not shown in the drawings), i.e., through-holes, provided in the covers 717.
- the flow sensor 721 detects the flow rate of the air sucked out from the cleaning unit 633 by the fan 719.
- Through-holes having a small diameter are formed in components such as the retention unit 699 of the cleaning unit 633 so as to allow air to flow in from the outside.
- the operation of the air conditioner 601 in a cooling mode and a heating mode and the indoor air flow inside the indoor unit 603 are the same as those according to the first embodiment, and, therefore, descriptions thereof are not repeated here.
- dust attached to the air filter 631 while operating the indoor unit 603 is removed by reciprocating the cleaning unit 633 along the surface of the air filter 631.
- the rotational driving force of the driving motor 635 is transmitted to the driving shaft 645, and the worm gear 647 is rotationally driven.
- the worm gear 647 engaged with the driving rack gear 649 is driven in a reciprocating manner along the driving shaft.
- the driving direction of the worm gear 647 is controlled by the rotational direction of the driving motor 635.
- the reciprocating movement of the worm gear 647 is transmitted to the upper transmitting unit 639, and the upper transmitting unit 639 is moved in a reciprocating manner together with the worm gear 647.
- the cylindrical portions 651 of the worm gear 647 are in contact with the contact units 665 of the upper transmitting unit 639, and, therefore, the worm gear 647 does not move more than a predetermined distance away from the driving rack gear 649. Since the driving rack gear 649 is interposed between the upper transmitting unit 639 and the adjusting unit 655, the upper transmitting unit 639 does not move more than a predetermined distance away from the driving rack gear 649.
- the reciprocating movement transmitted to the upper transmitting unit 639 is transmitted from the upper transmitting unit 639 to the lower transmitting unit 675. Since the pressing plate 673 of the upper transmitting unit 639 is in contact with the upper surface of the lower transmitting unit 675, the relative positions of the upper transmitting unit 639 and the lower transmitting unit 675 do not change even when the reciprocating movement is transmitted.
- the reciprocating movement of the lower transmitting unit 675 is transmitted from the grippers 709 to the brackets 701 of the cleaning unit 633 disposed on the lower surface of the air filter 631.
- the reciprocating movement transmitted to the brackets 701 is transmitted from the dust box 687 to the rotary brush 685.
- the rotary brush 685 moves in a reciprocating manner on the lower surface side of the air filter 631 and, at the same time, is rotationally driven by engagement of the pinion gears 693 and the rotary rack gears 677.
- the reciprocating and rotational movements of the rotary brush 685 cause the brush unit 691 of the rotary brush 685 to wipe the entire surface of the air filter 631 on the air inlet side so as to remove the dust collected on the air filter 631.
- the speed of the reciprocating movement of the rotary brush 685 and the rotational speed of the tips of the brush unit 691 differ by a predetermined value. This difference in speed enables the brush unit 691 to wipe the entire surface of the air filter 631.
- the diameters of the pinion gears 693 and the brush unit 691 may be set to have a predetermined ratio.
- the dust attached to the brush unit 691 is scraped off from the brush unit 691 when the brush unit 691 passes through the gap between the scrapers 705.
- the dust scraped off by the scrapers 705 drops through the gap between the scrapers 705 to the retention unit 699.
- the cleaning unit 633 that has removed dust from the air filter 631 is moved from an area where the air filter 631 is disposed to an area where one of the covers 717 of the dust-amount detecting unit 715 is disposed.
- the fan 719 rotates, and air is sucked into the cleaning unit 633.
- the flow sensor 721 detects the flow rate of the air sucked in by the fan 719 so as to estimate the amount of dust stored, based on the flow rate. While the cleaning unit 633 is cleaning the air filter 631, the fan 719 is turned off, and the amount of dust is not detected.
- the flow rate of the air sucked in by the fan 719 is reduced, whereas, if a small amount of dust is stored in the retention unit 699, the flow rate of the air sucked in by the fan 719 is increased.
- the flow sensor 721 configured to detect the flow rate of the air sucked in by the fan 719 may be provided on the dust-amount detecting unit 715 or, instead, a pressure-loss sensor configured to detect the pressure loss (pressure) in the air sucked in by the fan 719 may be provided.
- the type of sensor is not limited. In the case where a pressure-loss sensor is used, if a large amount of dust is stored in the retention unit 699, the pressure loss in the air flow sucked in by the fan 719 is large, whereas, if a small amount of dust is stored in the retention unit 699, the pressure loss in the air flow sucked in by the fan 719 is small.
- the amount of dust detected by the dust-amount detecting unit 715 is more than a predetermined amount, for example, the operator is warned by the indoor unit 603 that the dust inside the retention unit 699 must be removed.
- the air inlet grill 19 is lowered from the top panel 14. Since the lowering procedure of the air inlet grill 19 is the same as that according to the first embodiment, a description thereof is not repeated.
- the air inlet grill 19 includes the air filter 631, the cleaning unit 633, and the lower transmitting unit 675, by lowering the air inlet grill 19, the air filter 631, the cleaning unit 633, and the lower transmitting unit 675 are also simultaneously lowered from the top panel 14.
- the transmission path of the driving force from the driving motor 635 to the cleaning unit 633 is cut off between the upper transmitting unit 639 and the lower transmitting unit 675.
- the upper transmitting unit 639 and the lower transmitting unit 675 are disengaged by lowering the lower transmitting unit 675 together with the air filter 631 and so on.
- the cleaning unit 633 is moved to one of the edges (the right edge in Fig. 22 ) of the air filter 631.
- Fig. 34 illustrates a method of removing the cleaning unit 633 from the air filter 631 illustrated in Fig 22 .
- the lower transmitting unit 675 engaged with the cleaning unit 633 on the lowered air inlet grill 19 is removed. As shown in Fig. 29 , since the cleaning unit 633 and the lower transmitting unit 675 are engaged by the grippers 709 holding the brackets 701 from above, by pulling the grippers 709 upward, the lower transmitting unit 675 can be removed from the cleaning unit 633.
- Fig. 35 illustrates the method of removing the cleaning unit 633 from the air filter 631 illustrated in Fig. 22 .
- the air filter 631 is pivoted on a first edge (the right edge in Fig. 35 ) so as to lift a second edge (the left edge in Fig. 35 ).
- the cleaning unit 633 disposed on the lower surface side of the air filter 631 is exposed.
- the cleaning unit 633 is removed upward from the air inlet grill 19.
- Fig. 36 illustrates the method of removing the cleaning unit 633 from the air filter 631 illustrated in Fig. 22 .
- the main body 697 of the dust box 687 and the retention unit 699 of the cleaning unit 633 removed from the air filter 631 are separated. Then, the dust stored inside the retention unit 699 is removed.
- the cleaning unit 633, the air filter 631, and the air inlet grill 19 are re-assembled by following the above-described steps in the reversed order. Then, the air inlet grill 19 is raised.
- the driving force generated at the driving motor 635 can be transmitted to the cleaning unit 633 via the reciprocating unit 637, the upper transmitting unit 639, and the lower transmitting unit 675. Therefore, the cleaning unit 633 can be moved along the surface of the air filter 631 on the air inlet side by the driving force transmitted from the driving motor 635, and the rotary brush 685 can remove dust collected on the air filter 631.
- the driving motor 635, the reciprocating unit 637, and the upper transmitting unit 639 are disposed on the frame 641 disposed on the top panel 14.
- the cleaning unit 633 and the lower transmitting unit 675 are disposed on the air filter 631.
- the upper transmitting unit 639 and the lower transmitting unit 675 are detachably engaged with each other. Therefore, both detachment of the air inlet grill 19, including the air filter 631, from the chassis 15 and driving of the cleaning unit 633 by the driving motor 635 can be achieved.
- the upper transmitting unit 639 and the lower transmitting unit 675 are disengaged when the air inlet grill 19 is detached from the chassis 15, the detachment of the air inlet grill 19 is not hindered. Moreover, since the upper transmitting unit 639 and the lower transmitting unit 675 are engaged again when the air inlet grill 19 that has been detached is re-attached to the chassis 15, the driving of the cleaning unit 633 by the driving motor 635 is not hindered.
- the air filter 631 Since the lower transmitting unit 675 is disposed on the air outlet side of the air filter 631, the air filter 631 is interposed between the cleaning unit 633 and the lower transmitting unit 675. Therefore, the air filter 631, the cleaning unit 633, and the lower transmitting unit 675 can be detached from the chassis 15 as a unit.
- the air filter 631 and the cleaning unit 633 can be removed independently from the unit formed of the air filter 631, the cleaning unit 633, and the lower transmitting unit 675 removed from the chassis 15. Therefore, maintenance of the cleaning unit 633 and the air filter 631 can be easily carried out.
- the rotary brush 685 includes the rotary shaft 689 on which the rotary brush 685 rotates around the longitudinal axis thereof and the brush unit 691 that extends in the radial direction of the rotary shaft 689, by rotating the rotary shaft 689, the brush unit 691 rotates to remove dust collected on the air filter 631.
- the dust box 687 covers the rotary brush 685 and is capable of temporarily storing the dust removed from the air filter 631 by the rotary brush 685. Since the dust box 687 has an opening where the rotary brush 685 can contact the air filter 631, by letting the rotary brush 685 come into contact with the air filter 631, the dust collected on the air filter 631 can be removed by the rotary brush 685.
- the driving force that moves the cleaning unit 633 along the surface of the air filter 631 is converted into a rotational driving force for rotating the rotary brush 685.
- the rotary brush 685 also moves along the surface of the air filter 631.
- the driving force that moves the rotary brush 685 along the surface of the air filter 631 is converted into a rotational driving force for rotating the rotary brush 685.
- the pinion gears 693 are provided at both ends of the rotary shaft 689, the rotational driving force for rotating the rotary brush 685 is generated at both ends of the rotary shaft 689. Therefore, the rotary brush 685 can be stably rotated compared to a case in which the rotational driving force is generated at only one end of the rotary shaft 689.
- dust attached to the rotary brush 685 can be removed. More specifically, dust attached to the brush unit 691 is removed when the brush unit 691 passes through the gap between the scrapers 705 while the rotary brush 685 is rotating.
- the dust removed by the scrapers 705 is temporarily stored inside the dust box 687.
- the scrapers 705 function as covers that prevent the dust temporarily stored in the dust box 687 from escaping.
- the entire surface of the air filter 631 can be cleaned. More specifically, since the rotational speed of the tips of the brush unit 691 and the movement speed of the rotary brush 685 have a predetermined difference, the tips of the brush unit 691 are capable of wiping the surface of the air filter 631 at a predetermined speed. Therefore, the brush unit 691 of the rotary brush 685 contacts the entire air filter 631 and cleans the entire surface of the air filter 631 more thoroughly compared to when the difference between the rotational speed of the tips of the brush unit 691 and the movement speed of the rotary brush 685 is small.
- the sliding units 695 configured to reduce sliding resistance caused by the rotation of the rotary shaft 689 are provided between the rotary shaft 689 and the dust box 687, the life of the rotary shaft 689 and the life of the dust box 687 can be extended. More specifically, by providing the sliding units 695, friction generated at the contact area of the rotary shaft 689 and the dust box 687 is reduced, and the amount of abrasion at the contact area is reduced. Therefore, the life of the rotary brush 685 and the life of the dust box 687 can be extended.
- the dust-amount detecting unit 715 Since the dust-amount detecting unit 715 is provided, the amount of dust stored in the dust box 687 can be detected. Therefore, the dust box 687 can be prevented from being filled with dust, and a reduction in the ability to remove dust by the cleaning unit 633 can be prevented.
- the amount of dust stored in the dust box 687 can be detected by the fan 719 and the flow sensor 721 included in the dust-amount detecting unit 715. If a small amount of dust is stored in the dust box 687, the flow rate or the pressure of the air passing through the dust box 687 increases. On the contrary, if a large amount of dust is stored in the dust box 687, the flow rate or the pressure of the air passing through the dust box 687 decreases. By detecting the flow rate or pressure of the air with the flow sensor 721, the amount of dust stored in the dust box 687 can be estimated.
- the cleaning unit 633 can be stably moved. In other words, the same amount of driving force can be transmitted to both ends of the cleaning unit 633 and the cleaning unit 633 can be stably driven compared to a method in which the driving force is transmitted to substantially the central area of the cleaning unit 633.
- the number of reciprocating units 637 provided can be reduced and the size of the indoor unit 603 can be reduced compared to a method in which the driving force is transmitted to substantially the central area of the cleaning unit 633.
- the worm gear 647 engaged with the driving rack gear 649 is rotationally driven by the driving shaft 645, the worm gear 647 is reciprocated in the direction parallel to the driving rack gear 649. Since the reciprocating movement of the worm gear 647 is transmitted to the cleaning unit 633 via the upper transmitting unit 639 and the lower transmitting unit 675, the cleaning unit 633 is reciprocated.
- the distance between the worm gear 647 and the driving rack gear 649 can be prevented from increasing, and, therefore, the worm gear 647 can be prevented from disengaging from the driving rack gear 649.
- the upper transmitting unit 639 can be prevented from disengaging from the worm gear 647. For example, when sliding load generated between the worm gear 647 and the upper transmitting unit 639 and a resistive force generated when the cleaning unit 633 moves are applied to the upper transmitting unit 639, the upper transmitting unit 639 is prevented from disengaging from the worm gear 647.
- the air filter 631 Since the air filter 631 is supported by the air inlet grill 19, the air filter 631 can be removed from the chassis 15 together with the air inlet grill 19. In this way, the air filter 631 can be easily removed from the chassis 15.
- the cleaning unit 633 can be easily detached from and attached to the air filter 631.
- a space can be provided in the indoor unit 603 that contains the driving motor 635, the reciprocating unit 637, the upper transmitting unit 639, the lower transmitting unit 675, and the cleaning unit 633.
- the chassis 15, the indoor fan 21, the indoor heat-exchanger 23, and the other components included in the part of the indoor unit 603 that does not include the cleaning unit 633 and the components of the indoor unit 603 according to this embodiment can have some common structures. As a result, the production costs of the indoor unit 603 can be reduced.
- the reciprocating unit 637 may be disposed in substantially the central area of the cleaning unit 633, as in this embodiment.
- the position of the reciprocating unit 637 is not limited thereto, and, instead, two reciprocating units 637 may be disposed in the vicinities of both ends of the cleaning unit 633 to extend in the direction intersecting with the longitudinal direction of the cleaning unit 633.
- the cleaning unit 633 can be moved stably. In this way, compared to the present embodiment in which the driving force is transmitted to substantially the central area of the cleaning unit 633, the same amount of driving force can be transmitted to both ends of the cleaning unit 633, and the cleaning unit 633 can be driven more stably.
- each of the reciprocating unit 637 can be reduced in size.
- the reciprocating unit 637 may be constituted of the driving shaft 645, the driving rack gear 649, and the worm gear 647, as in this embodiment.
- the configuration of the reciprocating unit 637 is not limited thereto, and, instead, the reciprocating unit 637 may have a belt driving mechanism.
- the structure of the reciprocating unit 637 can be simplified. Moreover, the type of driving motor 635 provided for this belt driving mechanism can be selected more freely.
- the spacer 614 is provided between the chassis 15 and the top panel 14 .
- this spacer 614 is not required.
- the cleaning unit 633 is provided as an optional component, the spacer 614 is required for creating a space for disposing the cleaning unit 633.
