Description

  The present invention relates to an indoor unit of an air conditioner, and more particularly to an indoor unit of an air conditioner including a mechanism for cleaning an air filter.

  Since the indoor unit of the air conditioner is attached to an indoor wall or the like, it is required to reduce the volume of the main body casing as small as possible. This indoor unit includes a heat exchanger and a blower fan in its main casing. The indoor unit sucks indoor air into the main body casing by this blower fan, and blows it out of the main body casing through the heat exchanger. Air conditioning is performed by heating or cooling the indoor air in the heat exchanger, so if dust is contained in the sucked indoor air, it adheres to the heat exchanger and the blower fan, and the heat exchange capacity is reduced. Cause malfunction. Therefore, an air filter is attached to the air suction port of the air conditioning indoor unit in order to prevent intrusion of dust contained in the sucked air.

  However, when dust is removed by the air filter, the removed dust accumulates in the air filter and gradually clogs the air filter. This clogging of the filter may cause a decrease in the amount of indoor air sent to the heat exchanger by the blower fan and an increase in power consumption by the blower fan. In order to prevent such a problem, it is necessary to clean the air filter. In order to save the trouble of cleaning this air filter, an air conditioning indoor unit provided with a filter cleaning device that automatically cleans dust with a brush has been proposed.

  Such a filter cleaning mechanism is also required to be stored in as small a volume as possible in order to reduce the size of the indoor unit. The filter cleaning mechanism that moves and cleans the air filter with respect to the brush includes a cleaning unit that moves the air filter to clean the air filter, and a brush that scrapes dust attached to the air filter in contact with the air filter. And a filter cleaning member. In order to reduce the size of the filter cleaning mechanism, there is a driving force for driving the brush that is supplied from a cleaning unit (Patent Document 1 and Patent Document 2).

The filter cleaning member is also required to have a function as a dust box for storing scraped dust. As shown in Patent Document 1 and Patent Document 2, the filter cleaning member is an indoor unit so that it can be easily attached and detached because dust collected periodically is discarded or the brush is inspected or replaced. It is attached to the main body casing.

(Main body casing structure)
Next, the front grille of the main body casing will be described with reference to FIGS. FIG. 5 is a front view of a front grille constituting a part of the main body casing, FIG. 6 is a plan view of the front grille, and FIG. 7 is a side view of the front grille. As already described, the front panel 8 is attached to the front surface 5 b of the main body casing 5. At the front of the front grill 12, there are two openings 19a, 19b for maintenance of an air filter (described later). Since the decorative portion 25 in which striped irregularities are arranged is formed at a position lowering from the front portion of the front grill 12 to the back side, even if the front panel 8 is attached to the front grill 12, the openings 19a, 19b The upper portion is not blocked by the front panel 8, and the upper portions of the openings 19a and 19b serve as the sub suction port 6b. A main suction port 6 a is formed in the top surface 5 a of the front grill 12. The sub suction port 6b is formed at a position lower than the main suction port 6a by one step. However, the sub suction port 6b is provided above the indoor unit 2 and functionally, the sub suction port 6b is also the main suction port. It can be said that it is equivalent to the mouth 6a and is provided on the top surface 5a. A beam 26 is passed to the main suction port 6a. In addition to reinforcing the rigidity of the front grill 12, the beam 26 extending in the front-rear direction also has a function of holding the air filter by pressing the support frame of the air filter located below the main suction port 6 a.

  The air filter has a rectangular shape slightly shorter than the lateral width of the openings 19a and 19b. However, there is a frame 16 of the filter cleaning mechanism 15 between the air filter and the main body casing 5, and the air filter. And the main casing 5 are closed. Therefore, all the indoor air sucked from the main suction port 6a and the sub suction port 6b passes through the air filter.

  A recess 27 is formed below the openings 19 a and 19 b of the front grill 12. The filter cleaning member 14 is fitted into the recess 27 as described above. By the way, since only the filter cleaning member 14 is placed in the recess 27, the vibration of the front grill 12 is hardly transmitted from the front grill 12 to the filter cleaning member 14. The filter cleaning member 14 includes a brush side member to which a brush is attached and a dust box in which dust scraped off by the brush is placed. The configuration thereof will be described later. An opening 28 is formed in the recess 27. The filter cleaning mechanism 15 and the filter cleaning member 14 are connected through the opening 28. Further, in the opening portion 28, the driving gear of the filter cleaning mechanism 15 and the driven gear of the filter cleaning member 14 are engaged with each other, and the driving force is transmitted from the filter cleaning mechanism 15 to the filter cleaning member 14. Then, the brush is rotated together with the driven gear of the filter cleaning member 14. The screw hole 29 in the recess 27 is for fixing the filter cleaning mechanism 15 to the front grill 12 with screws.

  An opening 30 into which the display panel 13 shown in FIGS. 3 and 4 is fitted is formed under the concave portion 27 of the front grill 12, and the control part such as the display LED 10 is provided under the opening 30. A plurality of windows 31 are formed side by side in the width direction. An opening 32 constituting the air outlet 7 is formed below the opening 30 and the window 31. In addition, an outlet 33 for the filter cassette 21 of the humidifying duct 20 is provided on the left side of the front side of the opening 30 at the same height as the opening 30.

(Vertical cross-sectional structure of indoor unit)
FIG. 8 is a diagram showing an outline of a cross section of the indoor unit along line AA in FIG. 2, and FIG. 9 is a diagram showing an outline of a cross section of the indoor unit along line BB in FIG. 2. As shown in FIGS. 8 and 9, two sheets are provided on the top surface 5a of the main casing 5 on the downstream side of the main suction port 6a and the sub suction port 6b so as to face the entire surfaces of the main suction port 6a and the sub suction port 6b. Air filters 35a and 35b are arranged. The air filter 35a shown in FIG. 8 shares the left half of the main body casing 5 in the width direction, and the air filter 35b shown in FIG. 9 shares the right half of the main body casing 5 in the width direction. An indoor heat exchanger 36 is disposed further downstream of the air filters 35a and 35b. All of the room air that passes through the suction port 6 and reaches the indoor heat exchanger 36 passes through the air filters 35a and 35b and is subjected to dust removal.

  The indoor side heat exchanger 36 is configured by connecting a front side heat exchanger 36a and a back side heat exchanger 36b so as to form an inverted V shape in a side view. In a plan view seen from the top surface 5a, the front-side heat exchanger 36a is arranged at a position facing the front half of the main suction port 6a, and the rear-side heat exchanger 36b is arranged at a position facing the rear half. Has been. For this reason, when viewed as a whole of the suction port 6 including the sub suction port 6 b, the connecting portion between the front side heat exchanger 36 a and the back side heat exchanger 36 b is close to the back surface 5 d of the indoor unit 2. The front side heat exchanger 36a includes an upper front side heat exchanger 36aa and a lower front side heat exchanger 36ab. The front-side heat exchanger 36a extends from the vicinity of the air filters 35a and 35b directly below the main suction port 6a to the vicinity of the upper wall 7aa of the blowout passage 7a of the blowout port 7 and blows from the vicinity of the air filters 35a and 35b. There is an upper front heat exchanger 36aa in the upper part that occupies the upper half of the outlet passage 7a up to the vicinity of the upper wall 7aa, and a lower front heat exchanger 36ab in the lower part that occupies the lower half. Both the front-side heat exchanger 36 a and the rear-side heat exchanger 36 b are configured by arranging a large number of plate fins 37 in parallel with the width direction of the indoor unit 2 on the heat exchange pipe 38. When the indoor air sucked from the suction port 6 and passed through the air filters 35a and 35b passes between the plate fins 37, heat exchange occurs and air conditioning is performed. Therefore, in the vicinity of the plate fins 37, the indoor air easily generates a flow parallel to the surface of the plate fins 37 and hardly generates a flow in a direction perpendicular to the surface.

  An auxiliary heat exchanger 39 is provided upstream of the indoor heat exchanger 36 and adjacent to the front heat exchanger 36a. The auxiliary heat exchanger 39 is provided above the humidification duct 20 so as not to overlap the humidification duct 20 shown in FIG. Thereby, the way of the air conditioning of the humidified air supplied from the humidification duct 20 and room air can be varied. The auxiliary heat exchanger 39 can be switched by the first electromagnetic valve provided in the indoor unit 2 to function as a condenser or an evaporator. During the reheat dehumidifying operation, the auxiliary heat exchanger 39 is used as a condenser, while the indoor heat exchanger 36 is used as an evaporator to perform dehumidification while preventing a decrease in temperature. Further, when the auxiliary heat exchanger 39 is used as an evaporator like the indoor heat exchanger 36, the area contributing to heat exchange can be increased.

  Since the refrigerant is supplied in parallel to the indoor heat exchanger 36 and the auxiliary heat exchanger 39 through the heat exchange pipe 38, the amount of refrigerant flowing to the indoor heat exchanger 36 and the auxiliary heat exchanger 39 by the second electromagnetic valve. Can be different at the top and bottom. Thus, when sufficient air conditioning can be achieved even if the function of the lower part of the indoor heat exchanger 36 is reduced, heat can be efficiently exchanged using the upper part of the indoor heat exchanger 36. In addition, the first electromagnetic valve and the second electromagnetic valve can selectively use the indoor-side heat exchanger 36 and the auxiliary heat exchanger 39 in accordance with the combination of whether or not the humidifying duct 20 is used. Driving becomes possible. In addition, the 1st and 2nd solenoid valve 85 is arrange | positioned at the side of the indoor unit 2 (refer FIG. 19).

  On the downstream side of the indoor side heat exchanger 36, a substantially cylindrical cross flow fan 40 extends long along the width direction of the main body casing 5, and is provided in parallel with the width direction of the main body casing 5 together with the indoor side heat exchanger 36. It has been. The cross flow fan 40 is surrounded so as to be sandwiched between the inverted V-shaped indoor heat exchangers 36. The cross flow fan 40 is disposed at a position overlapping the front side heat exchanger 36a and the back side heat exchanger 36b at the same rate in a plan view as viewed from the top surface 5a of the main body casing 5, and is viewed from the front surface 5b. In view, it is disposed at a position overlapping with a part of the lower side of the upper front side heat exchanger 36aa and the lower front side heat exchanger 36ab. Moreover, the cross flow fan 40 is arrange | positioned so that it may protrude above the humidification duct 20 in front view. The cross flow fan 40 rotates clockwise in FIGS. 8 and 9 to generate an air flow.

  The blowout passage 7a downstream of the cross flow fan 40 is configured with a scroll member 41 on the back side. The scroll member 41 has substantially the same width as the opening 32 of the air outlet 7 of the main casing 5 in a front view. The upper end of the scroll member 41 is located above the upper end of the cross flow fan 40 and starts from a position shifted to the back side from the central axis of the cylindrical cross flow fan 40 in a side view. The lower end of the scroll member 41 is connected to the opening 32 of the air outlet 7. The guide surface 41 a of the scroll member 41 has a smooth curved shape having a center of curvature on the cross flow fan 40 side in a cross-sectional view, and the upper portion of the guide surface 41 a is disposed in the vicinity closest to the cross flow fan 40. It is arranged so as to gradually move away from the cross flow fan 40 as it goes down. At the upper end of the upper wall 7aa of the blowout passage 7a, a tongue portion 42 having a surface having a square cross section is provided. Of the surface of the tongue portion 42, the surface 42 a provided in the vicinity of the cross flow fan 40 faces the guide surface 41 a of the scroll member 41 with the cross flow fan 40 interposed therebetween. An opening formed by the surface 42a of the tongue 42 and the guide surface 41a of the scroll member 41 faces obliquely upward to the left in the cross-sectional views of FIGS. The direction of the indoor air flow in the vicinity of the cross flow fan 40 sucked by the cross flow fan 40 depends on the opening formed by the scroll member 41 and the tongue 42. Therefore, the room air blown out from the crossflow fan 40 passes through the blowout flow path 7a and is blown out from the blowout outlet 7, but the direction of blowout is adjusted by the wind direction adjusting blades 9 and 43. The right and left blowing directions viewed from the front of the indoor unit 2 are adjusted by the wind direction adjusting blades 43 close to the cross flow fan 40, and the upper and lower blowing directions are adjusted by the wind direction adjusting blades 9 at the outlet 7.

  A drain pan 44 that receives water droplets condensed by the front heat exchanger 36 a is disposed above the upper wall 7 aa of the air outlet 7. Further, the lower end of the lower front side heat exchanger 36ab is supported by the members constituting the drain pan 44, and the drain pan 44 serves to fix the indoor side heat exchanger 36.

  As shown in FIG. 8, an electrical component box 45 is disposed on the upper wall 7aa of the air outlet 7 so as to partially contact the upper wall 7aa. The lower end of the electrical component box 45 is below the drain pan 44, but the upper end of the electrical component box 45 is above the drain pan 44, and the electrical component box 45 is in the vicinity of the drain pan 44, in other words, the lower front side heat exchanger. Located in the vicinity of 36ab. The front surface of the electrical component box 45 is disposed so as to abut along the front grill 12. The electrical component box 45 is covered with a plastic drip-proof cover 46 from the upper surface to the rear surface. The drip-proof cover 46 starts from the upper surface of the electrical component box 45 and extends into the members constituting the drain pan 44, and the dropped water droplets can be guided to the drain pan 44. A printed wiring board 45a is fixed to the back side of the electrical component box 45, and various electrical components are mounted on the printed wiring board 45a, but the electrical components are not shown.

  The filter cleaning member 14 attached to the recess 27 on the electrical component box 45 shown in FIG. 8 includes a brush side member 48 that holds the brush 47, and a dust box 49 that holds dust scraped off by the brush 47. It is configured by combining. The depth of the lower portion of the filter cleaning member 14 (length in the front-rear direction of the indoor unit 2) is substantially the same as the depth of the upper portion of the electrical component box 45. The brush 47 is formed so that plastic straight hairs extend radially, and the brush 47 rotates counterclockwise in the cross-sectional view of FIG. Comb teeth 50 are inserted obliquely forward from below the brush 47. In addition, a plastic cylindrical rod-shaped member 51 for pushing dust into the dust box 49 is provided immediately below the teeth 50 of the comb portion. Spiral projections are attached to the surface of the columnar bar-shaped member 51, and the columnar bar-shaped member 51 rotates together with the brush 47, so that the dust scattered by the comb teeth 50 can be pushed into the dust box 49. Thereby, the dust accumulated in the dust box 49 can be compressed, and the number of times the dust collected in the dust box 49 is discarded can be reduced.

  The filter cleaning mechanism 15 is mounted on the filter cleaning member 14 so that the brush 47 of the filter cleaning member 14 contacts the air filters 35a and 35b. The two filter driving rollers 52a and 52b of the filter cleaning mechanism 15 are attached at positions facing the brush 47 with the air filters 35a and 35b interposed therebetween. FIG. 8 shows one filter driving roller 52b, and FIG. 9 shows the other filter driving roller 52a. The filter driving rollers 52a and 52b have pinion gears formed at both ends thereof, and the pinion gears mesh with rack gears formed at both ends of the air filters 35a and 35b, so that the air filters 35a and 35b Move.

  Here, the positional relationship between the suction port and the tongue will be described with reference to FIG. In the longitudinal sectional view, a portion of the upper surface 42a of the tongue portion 42 that is closest to the suction port 6 is connected to a portion of the suction port 6 that is closest to the front surface and located at the lowest position by a straight line. Assuming that the connected straight line is denoted by reference numeral L1, the area in front of the straight line L1 has a relatively small volume of indoor air, and the ratio of the air present ahead of the straight line L1 to the air conditioning of the indoor unit 2 is It is getting smaller. Therefore, the member arranged in front of the straight line L1 is difficult to prevent air conditioning. Since the filter cleaning member 14 is in front of the straight line L1, it does not contribute to an increase in ventilation resistance. Similarly, since the filter driving roller 52b of the cleaning mechanism driving unit 15c is also in front of the straight line L1, air conditioning is not hindered.

  Since the filter driving roller 52b is in front of the straight line L1, the contact point 82 between the brush 47 and the air filter 35 in the longitudinal sectional view is positioned in front of the straight line L1. In addition, since the brush 47 is formed of plastic straight hair, it does not come into contact with a point, and the contact 82 here is not a literal contact but has a meaning equivalent to a contacted portion. Since the contact 8 is in front of the straight line L1, the airflow is weak in the vicinity of the contact 82, and the dust dropped by the brush 47 is difficult to scatter. In other words, the flow of room air is weak below the filter cleaning member 14 in order to set the dust to be difficult to scatter.

  The air filters 35 a and 35 b are guided by the arm 17 and the blade 53 of the filter cleaning mechanism 15. The arm 17 has an upper guide groove 17a that draws a curve that gently curves along the vicinity of the upper portion of the front panel 8, the decorative portion 25 provided slightly backward from the front panel 8 and the top surface 5a. And another lower guide groove 17b provided below the upper guide groove 17a. The distance between the upper guide groove 17a and the lower guide groove 17b is slightly wider than the outer diameter of the tip circle of the pinion gear of the filter driving rollers 52a and 52b. When removing dust from indoor air, the filter cleaning mechanism 15 holds the air filters 35a and 35b so as to be positioned in the upper guide groove 17a. When cleaning the air filters 35a and 35b, the filter cleaning mechanism 15 makes the air filters 35a and 35b U-turn so as to be wound around the outer periphery of the filter driving rollers 52a and 52b. By making a U-turn, the filter driving roller 52a changes the moving direction of the air filters 35a, 35b from downward to upward, and guides the air filters 35a, 35b to the lower guide groove 17b. Since the dust is scraped off by the brush 47 while making the air filters 35a and 35b U-turn, the length of the filter cleaning mechanism 15 can be shortened, while the thickness of the filter cleaning mechanism 15 is increased by the diameter of the filter driving rollers 52a and 52b. Increase.

  A humidifying duct 20 is disposed on the upper wall 7aa of the air outlet 7 as shown in FIG. As can be seen by comparing the position of the humidification duct 20 in FIG. 9 with the position of the electrical component box 45 in FIG. 8, the humidification duct 20 is disposed at a position that substantially overlaps the electrical component box 45 in a side view. The humidifying duct 20 is formed with a cavity portion 54 that serves as a flow path for humidified outside air, and a humidified outside air supply port 55 is formed above the cavity portion 54. The air supply port 55 is disposed so that a space of a predetermined length is formed between the lower front surface side heat exchanger 36ab. Thereby, the humidified air supplied from the air supply port 55 is set so as to spread in the width direction of the indoor unit 3. The hollow portion 54 is partitioned by the prefilter 21, and all the outside air supplied from the air supply port 55 to the inside of the main body casing 5 passes through the prefilter 21. Therefore, it is not necessary to arrange the air filters 35a and 35b in front of the air supply port 55, and the arrangement area of the air filters 35a and 35b can be narrowed. The pre-filter 21 is configured to be detachable from the lower side of the front surface 5a of the indoor unit 2 toward the upper side of the back side.

(Filter cleaning mechanism)
Here, the filter cleaning mechanism 15 shown in FIGS. 8 and 9 will be described. 10 is a front view of the filter cleaning mechanism, FIG. 11 is a left side view of the filter cleaning mechanism, and FIG. 12 is a bottom view of the filter cleaning mechanism. FIG. 13 shows the relationship between the cleaning mechanism driving unit of the filter cleaning mechanism and the air filter.

  The filter cleaning mechanism 15 includes two left and right holding portions 15a and 15b in order to hold the two air filters 35a and 35b shown in FIG. The air filters 35a and 35b support a filter portion 35ab that allows room air to pass therethrough for filtering by a thin support frame 35aa. As already described with reference to FIGS. 8 and 9, the filter driving motors 56a and 56b and the filter driving rollers 52a and 52b for driving the air filters 35a and 35b shown in FIG. Is configured. Factors that increase the thickness of the filter cleaning mechanism 15 because the filter driving rollers 56a and 56b are relatively difficult to downsize due to the relationship with the material of the plastic air filters 35a and 35b. It has become.

  The holding portions 15a and 15b are composed of an arm 17 and a frame 16 constituted by a blade 53 and a beam 59 passed between the arms 17. Since the frame 16 is configured by combining thin members such as the blade 53 and the beam 59 in order to improve ventilation, a space is formed inside, and the space can be effectively utilized by using this space effectively. Effective use is planned. That is, the holding portions 15a and 15b are provided with filter driving motors 56a and 56b for driving the filter driving rollers 52a and 52b, respectively, at positions overlapping the air filters 35a and 35b when viewed from the front. Is attached. The filter driving motor 56a is disposed between the upper guide groove 17a and the lower guide groove 17b shown in FIG. In other words, between the position of the air filter 35a before changing the moving direction by the filter driving roller 52a and the position of the air filter 35a after changing the moving direction by the fill driving roller 52a, the filter driving motor. 56a is arranged. The frame 16 is fixed by screwing the fixing portion 16 c to the main body casing 5. The central fixing portion 16c is fixed to the screw hole 29 of the front grill 12 shown in FIG. Further, the claw 16d is inserted into the main body casing 5 to fix the frame 16 behind.

  Since room air passes through the air filter 35a, the filter driving motor 56a generates ventilation resistance at the portion where it overlaps with the air filter 35a. Therefore, the filter driving motor 56a is arranged at the left end of the filter cleaning mechanism 15 and is as air as possible. The filter 35 is attached so that the area overlapping the filter 35 is reduced. For the same reason, a filter driving motor 56b is attached to the left end of the holding portion 15b of the filter cleaning mechanism 15. The filter driving motors 56a and 56b are arranged so as to overlap in a side view. Further, as shown in FIG. 9, since the suction port 6 is at the upper portion and the indoor air flowing from the suction port 6 to the cross flow fan 40 is directed to the lower back side, the filter driving motors 56a and 56b are connected to the filter driving rollers 52a, By arranging it close to 52b, the ventilation resistance is reduced.

  The driving force generated by the filter driving motors 56a and 56b is transmitted to the filter driving rollers 52a and 52b by a plurality of gears. A gear connecting the filter driving roller 52a and the filter driving motor 56b is housed in a gear box 57 shown in FIG.

  In addition to driving the air filters 35a and 35b, the filter cleaning mechanism 15 is provided with a brush driving motor 58 for driving the brush 47 shown in FIGS. The brush drive motor 58 is also disposed at a position overlapping the air filter 35a in front view. In addition, when viewed from the side, the brush driving motor 58 is disposed at a position overlapping the filter driving motors 56a and 56b. The brush driving motor 58 is also included in the cleaning mechanism driving unit 15c.

  A latching protrusion 16 b for fixing to the filter cleaning member 14 is provided at the lower portion of the frame 16 of the filter constituting mechanism 15.

(Filter cleaning member)
14 is an exploded view of the filter cleaning member, FIG. 15A is a front view of the filter cleaning member, FIG. 15B is a plan view of the filter cleaning member, and FIGS. 16A, 16B, and 16B. 16 (c), FIG. 16 (d), and FIG. 16 (e) are cut along lines EE, FF, GG, HH, and I-I in FIG. 15 (b), respectively. FIG. The filter cleaning member 14 includes a brush 47, a brush side member 60 that holds the brush 47, and a lid member 61 that covers the brush side member 60. The lid member 61 is pivotably hooked to the brush side member 60 by a hinge 65, and is fixed to the brush side member 60 with the lid closed by a central locking member 66 (FIG. 15B). FIG. 16 (c) and FIG. 16 (e)). The brush side member 60 and the lid member 61 are combined to form a space for putting dust inside, and constitute a dust box 49 (FIGS. 18B and 16D). On one side of the brush side member 60, teeth 50 of the comb portion are arranged corresponding to the length of the brush 47 (FIG. 14).

  The shaft 63 of the brush 47 is rotatably fitted to the bearing 62 of the brush side member 60 (FIG. 16A). Cap members 63 a having an outer diameter substantially equal to the inner diameter of the bearing 63 are fitted into both ends of the shaft 63 of the brush 47 so that there is no play between the shaft and the bearing 63. The shaft 63 of the brush 47 is formed of a highly rigid cylindrical plastic or metal that is difficult to bend. A driven gear 64 is attached to the shaft 63 of the brush 47 (FIGS. 15B and 16B). The driven gear 64 meshes with the drive gear 58 b by fixing the filter cleaning member 14 to the filter cleaning mechanism 15. A cylindrical rod-shaped member 51 is attached to the lid member 61, and a gear 67 is fixed to the rod-shaped member 51 (FIGS. 14 and 15B). The gear 67 of the rod-like member 51 is connected to the driven gear 64 of the brush 47 and rotates as the brush 47 rotates.

  As shown in FIG. 16C, the locking member 66 is provided with a hook-shaped hooking portion 68b having a hook-shaped cross section along with a rail 68a having a cross-sectional shape. On the other hand, the brush side member 60 is provided with a locking projection 69b, and the lid member 61 is provided with a rail 14b having a C-shaped cross section. The rail 68a having a C-shaped cross section is slidably fitted to a rail 14b having a C-shaped cross section. When locking with the locking member 66, the locking member 66 is slid to bring the rail 14b of the lid member 61 and the latching protrusion 69b of the brush side member 60 together, and the rail 68a having a cross-sectional shape and the cross-sectional surface It is sandwiched between the hook portion 68b of the mold. As a result, the locking protrusion 69 b is hooked by the lock member 66, and the lid member 61 is fixed to the brush side member 60. In order to bring the brush side member 60 and the lid member 61 into close contact with each other, the latching protrusion 69b gradually increases in thickness toward the left hand when viewed from the front, and is formed so that the fitting can be made dense. . Further, the claws 70 at both ends in the longitudinal direction of the lid member 61 are hooked on the brush side member 60 to assist the fixation with the brush side member 60 (FIG. 16 (e)).

  The method of fixing the filter cleaning member 14 to the filter cleaning mechanism 15 by the lock members 18a, 18b, 18c, and 18d is performed in the same manner as the method of fixing the lid member to the brush side member 60 by the lock member 66. FIG. 17 is a partially enlarged view of the area Ar1 in FIG. The locking member 18c is provided with a hook 18cb having a bowl-shaped cross section, together with a rail 18ca having a cross-sectional shape. On the other hand, the filter cleaning member 14 is provided with a rail 14a having a U-shaped cross section and a bent end in a bowl shape. The rail 18ca having a C-shaped cross section is slidably fitted to the rail 14a having a U-shaped cross section. When locking with the lock member 18c, the rail 14a of the filter cleaning member 14 and the latching protrusion 16b of the frame 16 of the filter cleaning mechanism 15 are brought together by sliding the lock member 18c. It is sandwiched between 18ca and a hook 18cb having a saddle-shaped cross section. As a result, the locking protrusion 16b is locked by the lock member 18c, and the filter cleaning member 14 is directly fixed to the frame 16. Similarly to the latching protrusion 69b, the latching protrusion 16b is also tapered in the left-right direction so that the fitting becomes tight as the lock member 18c slides to the right in front view. Similarly to the lock member 18c, the lock members 18a, 18b, and 18d also latch the latch protrusions 16b. As a result, the central axis of the filter driving roller 52a is located at four locations near the center where the left and right ends of the filter cleaning member 14 where the lock members 18a, 18b, and 18d are disposed and the driven gear 64 and the driving gear 58b mesh. And the distance L2 between the center of the shaft 60 of the brush 47 is firmly maintained. Thereby, the distance between the brush 47 and the air filter 35a can be kept constant over the entire width of the filter cleaning member 14.

(Parts below the filter cleaning member)
18 and 19 are a front view and a perspective view of the indoor unit with the front grill removed. As shown in FIG. 18, there is a recess 27 in which the filter cleaning member 14 is mounted. As shown in FIG. 19, the filter cleaning member 14 is mounted directly below the cleaning mechanism drive unit 15c.

  Below the filter cleaning member 14, a humidification duct 20, an electrical component box 45, a power supply box 80, and the like are arranged. As described with reference to FIGS. 8 and 10, the filter driving roller 52 a and the filter driving motors 56 a and 56 b constituting the cleaning mechanism driving unit 15 c have a relatively large cross-sectional shape in the indoor unit 2. ing. Therefore, the filter cleaning member 14 also has a depth that matches the cleaning mechanism driving unit 15c.

  When a space for accommodating the humidifying duct 20, the electrical component box 45, the power supply box 80, and the like is formed between the blowout port 7 and the filter cleaning member 14, the depth of the filter cleaning member 14 and the humidifying duct 20, the electrical component box 45, and the like are approximately the same. Therefore, the space in the indoor unit 2 can be used effectively. Further, since the distance between the electrical component box 45 and the filter driving motors 56a and 56b can be shortened, the wiring distance between the electrical component box 45 and the filter driving motors 56a and 56b is shortened.

  On the right side of the electrical component box 45 from the front, a power supply box 80 in which a terminal board for commercial power supply such as an alternating voltage of 100 volts and 200 volts is housed. Power for the electrical component box 45 is also supplied from the power supply box 80. By arranging the power supply box 80 along with the electrical component box 45 along the longitudinal direction of the indoor unit 2, not only the power supply distance to the electrical component box 45 is shortened, but also the power supply box 80 is electrically connected in a side view. Since it is arranged at a position overlapping with the product box 45, the space can be effectively used.

  A speaker 81 is disposed on the left side of the electrical component box 45 from the front. The speaker 81 is provided between the electrical component box 45 and the humidification duct 20 so as to effectively use the space. Since the speaker 81 is close to the electrical component box 45, the wiring between the speaker and the electrical component box 45 is shortened.

  By arranging as described above, the width W1 in which the air filters 35a and 35b can be arranged can be made larger than the width W0 of the indoor unit 2. Moreover, the width | variety of the indoor side heat exchanger 36 can be taken large. Thereby, the effective length of the heat exchanger which contributes to heat exchange can be extended compared with the past.

<Modification>
(A)
In the above embodiment, as the filter driving mechanism, the brush driving motor 58 supplies a driving force for rotating the brush 47 via the driving gear 58b and the driven gear 64 which are spur gears. What transmits the driving force to the brush 47 is not limited to the combination of spur gears, and may be a transmission mechanism other than gears as long as it can be separated between other types of gear combinations and transmission mechanisms. The force generating means is not limited to a motor.

(B)
In the above embodiment, as the filter driving mechanism, the filter driving rollers 52a and 52b are used to drive the air filters 35a and 35b. However, the means for relatively moving the air filters 35a and 35b and the brush 47 is as follows. The present invention is not limited to the filter driving rollers 52a and 52b of the above embodiment. The filter drive mechanism may be any mechanism that moves the air filters 35a, 35b and the brush 47 relative to each other while keeping the air filters 35a, 35b and the brush 47 at a predetermined interval.

(C)
In the said embodiment, although the filter cleaning mechanism which cleans the sheet-like air filters 35a and 35b was demonstrated, the continuous body with which the air filter was connected by the cylinder shape may be sufficient, and the same effect as the said embodiment. Play.

(D)
In the above embodiment, the lock members 18a, 18b, 18c, and 18d that are fixed and released by sliding have been described. However, the lock mechanism may be another mechanism, and does not easily deviate from the fixed state. A locking member that is fixed to is preferable.

<Features>
(1)
As shown in FIG. 9, the filter cleaning member 14 holding the brush 47 is directly fixed to the frame 16 of the filter cleaning mechanism 15. Therefore, the brush 47 can be held by the filter cleaning member 14 while maintaining a proper positional relationship between the brush 47 and the air filters 35a and 35b. As a result, the lock members 18a, 18b, 18c, and 18d (fixing means) can be attached and detached as necessary. At the same time, an appropriate positional relationship between the brush 47 and the air filters 35a and 35b is maintained by directly fixing the lock members 18a, 18b, 18c and 18d to the frame 16, and a positional relationship between the brush 47 and the air filters 35a and 35b. It is possible to prevent problems at the time of brush driving due to deviation.

(2)
Even when the driving force is transmitted from the driving gear 58b of the brush driving motor 58 (filter driving mechanism) to the driven gear 64 of the brush 47, the positional relationship between the two gears 64 and 58b is determined by the lock members 18a, 18b, 18c and 18d. I can keep it. As described above, since the driving force is transmitted from the driving gear 58b of the two spur gears to the driven gear 64 of the brush 47, the driving force can be transmitted with a simple configuration. Therefore, the filter cleaning mechanism 15 can be downsized, and the indoor unit 2 can be downsized.

(3)
The lock members 18a and 18b are arranged in the vicinity of the left and right sides of the driven gear 64 with the driven gear 64 interposed therebetween. Thus, since there is a lock position on the left and right with respect to the stress generated between the drive gear 58b and the driven gear 64, the filter cleaning member around the drive gear 58b and the driven gear 64 due to the stress at the time of gear driving. 14 and the filter cleaning mechanism 15 can be suppressed. For example, the gap between the gears 64 and 58b is not opened, and problems such as the gears being disengaged can be prevented.

(4)
Since there are lock positions at three points in the vicinity of the driven gear 64 (at least one of the lock member 18a and the lock member 18b) and in the vicinity of both ends of the filter cleaning member 14 (lock members 18c and 18d), a relatively long filter Even if it is the cleaning member 14, since the positional relationship of the brush 47 and the air filters 35a and 35b can be maintained even if the plastic cleaning member 14 does not increase the rigidity of the filter cleaning member 14 so much, an inexpensive filter cleaning mechanism is provided. it can.

(5)
Since the dust box 47 can be attached and detached together with the filter cleaning member 14 that is detachably fixed to the frame 16 by the lock members 18a, 18b, 18c, and 18d (fixing means), dust can be easily discarded. Further, since the fixing mechanism by the lock members 18a, 18b, 18c, and 18d is simple and there is no extra mechanism for attaching to the main casing, the amount of dust stored in the dust box 47 can be increased. Moreover, attachment / detachment workability is not impaired. Therefore, the number of dust disposal times can be reduced, and the burden during maintenance can be reduced.

(6)
Since the moving direction of the air filter 47 can be changed, the area occupied by the filter drive mechanism 15 can be reduced by the filter drive rollers 52a and 52b to facilitate downsizing, and the filter drive rollers 52a and 52b can be used for brushing. 47 and the air filters 35a and 35b can be easily maintained at a constant distance, and the appropriate positions of the brush 47 and the air filters 35a and 35b can be easily maintained.

(7)
Since the filter cleaning member 14 can be attached to and detached from the main body casing 5 by attaching and detaching it with the frame 16 and the lock members 18a, 18b, 18c and 18d installed in the main body casing 5, maintenance is facilitated.
