(Brush 23)
As shown in FIG. 7, the bristles 23 a of the brush 23 are located on the opposite side of the roller 34 with the air filter 20 interposed therebetween and are in contact with the air filter 20. That is, the roller 34 is above the air filter 20, and the brush 23 is below the air filter 20. A brush side gear 51 is connected to the rotating shaft 55 of the brush 23, and a motor side gear 52 is connected to the rotating shaft of the brush drive motor 32. The brush side gear 51 is connected to both ends of the rotating shaft 55. The motor side gear 52 and the intermediate transmission gear 53 mesh with each other, the drive side gear 54 and the intermediate transmission gear 53 mesh with each other, and the drive side gear 54 and the brush side gear 51 mesh with each other. Thereby, the driving force of the brush drive motor 32 is transmitted to the brush 23 via the brush side gear 51. Since the brush 23 is positioned between the straight front storage path 46 and the curved rear storage path 47, the brush 23 is moved when the air filter 20 moves between the front storage path 46 and the rear storage path 47. The entire area of the mesh 20a of the air filter 20 can be contacted. As shown in the exploded perspective view of the movable panel in FIG. 9, the bristles 23 a of the brush 23 are fixed to the rotation shaft 55.

In FIG. 9, the dust box 24 has a dust intake port 56 near the upper air outlet 4, and supports the rotary shaft 55 via bearings 57 at both ends in the longitudinal direction of the dust intake port 56. Further, a comb portion 58 is attached to the dust intake port 56 to remove the dust scraped off from the air filter 20 by the brush 23 from the brush 23. Since the hair 23a of the brush 23 enters the comb portion 58, a large frictional resistance is generated and the brush 23 is difficult to rotate.

  The dust box 24 is attached toward the rotating shaft side of the movable panel 6, and the brush 23 is closer to the outlet 4 at the end of the suction port 3, so that the movable panel 6 can be seen from FIG. 2B. Rotates and opens the suction port 3 together with the brush 23 from the air filter 20 and does not obstruct the path of the suction air. Further, in order to smoothly direct the air that is directed to the dust box 24 to the air filter 20, the surface 59 of the dust box 24 that faces the suction air is inclined to reduce the air resistance. When the dust box 24 is fixed to the moving panel 6, the moving panel 6 is structurally reinforced by the dust box 24, so that the usage rate of the sheet metal member conventionally used for reinforcement is reduced.

(Air filter cleaning operation)
In the air conditioning indoor unit 2, the air filter 20 is automatically cleaned by a remote controller or periodically by the control device 25 when the user needs it. The mechanism will be described below.

  As shown in FIG. 8A, during operation, the rack gear 37 of the air filter 20 is housed in the front storage path 46, and one end of the rack gear 37 (hereinafter referred to as the first end portion 37a) is a pinion gear. 36 is engaged. When the roller 34 rotates, the rotation is transmitted from the pinion gear 36 to the rack gear 37, and the rack gear 37 of the air filter 20 is conveyed by the roller 34 toward the rear storage path 47. As the roller 34 continues to rotate, the first end 37 a of the rack gear 37 reaches the end of the rear storage path 47.

  When the first end portion 37a of the rack gear 37 reaches the end of the rear storage path 47, the first end portion 37a rotates the lever of the position detection switch 27 to turn it on. The control device 25 determines that the first end portion 37 a of the rack gear 37 has reached the end of the rear storage path 47 from the ON signal output from the position detection switch 27, and stops the rotation of the roller 34. At this time, the entire region of the rack gear 37 of the air filter 20 is accommodated in the rear storage path 47, and the other end of the rack gear 37 (hereinafter referred to as the second end portion 37 b) meshes with the pinion gear 36.

  As shown in FIGS. 7 and 8, when the air filter 20 moves, dust attached to the surface of the air filter 20 is scraped off by the brush 23 and stored in the dust box 24 shown in FIG. The brush 23 rotates at least during a period in which the air filter 20 is moving from the front storage path 46 to the rear storage path 47, and the rotation direction is a direction opposite to the traveling direction of the air filter 20.

  When the air filter 20 moves from the front storage path 46 to the rear storage path 47 and the dust removal is completed, the control device 25 rotates the roller 34 in the reverse direction. Since the second end portion 37 b of the rack gear 37 of the air filter 20 meshes with the pinion gear 36, rotation is transmitted from the pinion gear 36 to the rack gear 37, and the air filter 20 is transferred to the front storage path 46 side by the roller 34. It is conveyed to. As the roller 34 continues to rotate in the reverse direction, the second end 37 b of the rack gear 37 reaches the end of the front storage path 46.

  When the second end 37b of the rack gear 37 reaches the end of the front storage path 46, the second end 37b rotates the lever of the position detection switch 27 to turn it on. The control device 25 determines that the second end portion 37 b of the rack gear 37 has reached the end of the front storage path 46 from the ON signal output from the position detection switch 27, and stops the rotation of the roller 34. At this time, the rack gear 37 of the air filter 20 is housed in the front storage path 46, and the first end portion 37 a of the rack gear 37 is engaged with the pinion gear 36.

Cannot rotate to the center. The moving panel 6 can be moved up and down by feeding and winding the wire 14 in a state in which the connection between the rotating member 61 and the moving panel 6 is released.

(Elevating device 13)
FIG. 12 is an exploded perspective view of the lifting device. FIG. 13 is a layout diagram of components inside the lifting device. 12 and 13, the lifting device 13 includes a wire 14, a pulley 72, a bobbin 73, a winding gear 74, a driving gear 75, a lifting motor 29, a switch 26, and a case 78.

  The pulley 72 has a pulley portion 72 a and a cam portion 72 b that are integrally formed. The pulley portion 72 a supports the wire 14 and rotates as the wire 14 moves. The cam portion 72b includes a small-diameter curved surface, a large-diameter curved surface, and a plane connecting both the curved surfaces.

  The bobbin 73 winds up the wire 14. The winding gear 74 is connected coaxially with the bobbin 73 and rotates integrally. The drive gear 75 meshes with the winding gear 74 and rotates the bobbin 73. The elevating motor 29 is a stepping motor and rotates the drive gear 75. The number of rotations of the lifting motor 29 is controlled by the number of pulses supplied from the control device 25.

  The switch 26 is a micro switch having a lever 77a and is turned on when the lever 77a is pressed. The lever 77a is always in contact with the cam portion 72b of the pulley 72 and is pushed when facing the large-diameter curved surface of the cam portion 72b. The switch 26 is also electrically connected to the control device 25 by a wire harness.

  The case 78 is divided into a support case 78a and a cover 78b. The support case 78a is formed with a first shaft 79a that supports the pulley 72, a second shaft 79b that supports the bobbin 73 and the winding gear 74, and a third shaft 79c that supports the switch 26. The cover 78b covers and protects each component supported by the support case 78a.

(Operation of lifting device 13)
In FIG. 13, when the elevating device 13 feeds the wire 14, the elevating motor 29 rotates the drive gear 75 in the CCW direction and rotates the winding gear 74 in the CW direction. As a result, the bobbin 73 rotates in the direction of feeding the wire 14.

  On the other hand, when the lifting device 13 winds up the wire 14, the lifting motor 29 rotates the drive gear 75 in the CW direction and rotates the winding gear 74 in the CCW direction. As a result, the bobbin 73 rotates in the direction of winding the wire 14. The feeding amount and winding amount of the wire 14 are proportional to the rotation amount of the lifting motor 29, and the feeding amount and winding amount of the wire 14 are controlled by controlling the number of pulses that the control device 25 supplies to the lifting motor 29. Is controlled.

  Since the movable panel 6 is connected to the tip of the wire 14, tension is always generated in the wire 14, and when the wire 14 is drawn out or wound up, the pulley portion 72 a is connected to the wire 14. It is rotated by the frictional force. At this time, since the cam portion 72b also rotates, the switch 26 issues an ON signal when the lever 77a faces the large-diameter curved surface of the cam portion 72b, and issues an OFF signal when the lever 77a faces the small-diameter curved surface. While the pulley 72 is rotating, an ON signal and an OFF signal are alternately generated, and these signals are all input to the control device 25.

  However, when the wire 14 is loosened due to some reason, for example, when the wire 14 is drawn out for maintenance and the moving panel 6 is lowered, the moving panel 6 is moved before reaching a predetermined feeding amount. When landing on a table or the like and stopping, the frictional force between the wire 14 and the pulley portion 72a decreases, and the pulley 72 stops. For this reason, either the on signal or the off signal is continuously output from the switch 26. At this time, since the signal from the switch 26 is constant when the lifting motor 29 is rotating, the control device 25 estimates that the movable panel 6 has been stopped by some obstacle, and immediately the lifting motor 29. Stop.

(Locking device 9)
When the moving panel 6 closes the suction port 3 as shown in FIG. 2A, the moving panel 6 is supported by the main body 5 by the hinge connecting device 21 and the lifting device 13 shown in FIG. . The air conditioning indoor unit 2 is a locking device so that the moving panel 6 does not fall even when the hinge coupling device 21 malfunctions due to unforeseen causes to release the support of the moving panel 6 and the wire 14 of the lifting device 13 is loosened. 9 is further provided.

  FIG. 14 is a perspective view of the locking device. In FIG. 14, the locking device 9 includes a movable body 10, a first holding part 11, a second holding part 12, a motor 30 and a spring 85. The movable body 10 has a quadrangular prism shape, and an inclined surface 811 is formed at one end thereof, and a long side surface 812 having the longest overall length is formed with a rack gear 81a that meshes with a predetermined gear, and below the rack gear 81a. Is formed with a hollow portion 81b. The movable body 10 is held in a movable state by the first holding portion 11 with the long side surface 812 directed vertically upward.

  The first holding portion 11 is a rectangular parallelepiped housing having an open top surface and one side surface, a guide groove 82a is formed on the bottom surface, and the movable body 10 moves horizontally along the guide groove 82a. Both ends of the guide groove 82a are sandwiched between walls 821 and 822, and a through-hole 82b through which the movable body 10 passes is formed in one wall 821. A wall 823 is adjacent to the walls 821 and 822 sandwiching both ends of the guide groove 82a, and a plate-like protrusion 82c that protrudes in a direction orthogonal to the guide groove 82a is formed on the wall 823. When the movable body 10 is held by the first holding part 11, the inclined surface 811 is always located outside the first holding part 11, and the rack gear 81 a is always located inside the first holding part 11. The plate-like protrusion 82 c of the first holding part 11 passes through the hollow part 81 b of the movable body 10.

  The wall 823 fixes the motor 30 and rotatably supports a pinion gear 84 a connected to the rotation shaft of the motor 30. The pinion gear 84a meshes with the rack gear 81a of the movable body 10 to form a rack and pinion mechanism. A spring 85 is accommodated in the hollow portion 81 b of the movable body 10. The spring 85 is a compression coil spring and is sandwiched between the end of the hollow portion 81b and the plate-like protrusion 82c.

  The second holding unit 12 is a solid object in which a guide hole 83a through which the movable body 10 passes is formed, and is installed on the movable panel 6 side. A smooth curved surface 831 is formed on the upper surface of the second holding part 12.

(Operation of the locking device 9)
In FIG. 14, the movable body 10 is in a state of being held by the first holding body 82 and the second holding body 83, and when the motor 30 rotates the pinion gear 84a in the CCW direction in this state, the pinion gear 84a The rotational motion is converted into linear motion by the rack gear 81a, and the movable body 10 slides toward the wall 822. When the movable body 10 moves a predetermined distance, the movable body 10 moves away from the guide hole 83a of the second holding portion 12. Since the second holding body 83 that does not hold the movable body 10 is allowed to move in the vertical direction, it does not prevent the moving panel 6 from being lowered.

  The movement of the movable body 10 shortens the distance between the side surface of the hollow portion 81b and the plate-like protrusion 82c, so that the spring 85 is compressed and stores a repulsive force. While the electric power is supplied, the motor 30 rotates against the increasing repulsive force of the spring 85. However, when the electric power is not supplied, the motor 30 rotates reversely due to the repulsive force of the spring 85, and the movable body 10 returns to the original state. Return to the position.

  When the movable panel 6 is not lowered and the second holding part 12 is not moving, the movable body 10 enters the guide hole 83a of the second holding part 12. On the other hand, when the movable panel 6 is lowered and the second holding unit 12 is moving, the mobile panel 6 stands by on the path where the second holding unit 12 returns. Then, when the movable panel 6 is raised and the suction port 3 is closed, the second holding unit 12 returns to the movable body 10 by pushing the movable body 10 against the inclined surface 811 of the movable body 10.

  The movable body 10 pushed by the second holding part 12 moves horizontally and compresses the spring 85. When the second holding portion 12 is completely restored, the movable body 10 passes through the guide hole 83a of the second holding portion 12. As a result, the movable body 10 prevents the moving panel 6 from being lowered.

(Moving panel open / close operation)
FIG. 15 is a perspective view of a state in which the moving panel opens the suction port. In FIG. 15, when the locking device 9 releases the lock and the elevating device 13 feeds the wire 14 in a state where the hinge connecting device 21 connects the moving panel 6, the moving panel 6 is lowered by its own weight. However, since the end portion of the moving panel 6 is connected to the hinge connecting device 21, the moving panel 6 rotates in the direction of opening the suction port 3 with the end portion as an axis.

  On the other hand, when the lifting / lowering device 13 winds the wire 14, the movable panel 6 is lifted, but since the end of the movable panel 6 is connected to the hinge connecting device 21, the movable panel 6 has the suction port with the end as an axis. 3 is turned in the closing direction. When the moving panel 6 completely closes the suction port 3, the locking device 9 locks the moving panel 6.

(Moving panel up and down operation)
FIG. 16 is a perspective view of a state where the movable panel is lowered. In FIG. 16, when the hinge connecting device 21 releases the connection with the end of the moving panel 6, the locking device 9 releases the lock of the moving panel 6, and the lifting device 13 extends the wire 14, the moving panel 6 is Descent due to its own weight. On the other hand, when the lifting device 13 winds the wire 14, the moving panel 6 is raised, and when the moving panel 6 completely closes the suction port 3, the locking device 9 locks the moving panel 6.

  Since the movable panel 6 is suspended by two wires and descends together with the dust box 24, the total weight of the movable panel 6 including the dust box 24 is increased, and the posture is not unstable due to the airflow in the room. . However, the center of gravity fluctuates when dust is concentrated in the dust box 24. For this reason, in the present embodiment, the position of the dust box 24 on the movable panel 6 is substantially the same as the position when the dust box 24 is full of dust and the position when the dust box 24 is empty. Dimensions and position are set.

  Specifically, the total length of the dust box 24 in the longitudinal direction is set to be 1/2 or more of the total length of the movable panel 6 in the longitudinal direction. Further, the total length of the dust box 24 in the width direction is set to 1/3 or more of the total length of the movable panel 6 in the width direction. And the dust box 24 is arrange | positioned near the rotating shaft when the movable panel 6 rotates.

  When the dust stored in the dust box 24 is discarded, the dust box 24 is removed from the moving panel 6 of the air conditioning indoor unit 2. However, since the dust box 24 is attached to the moving panel 6 that cannot be reached by the user, the user lowers the moving panel 6 to a maintenance position where the user can reach, and then moves the dust box 24 to the moving panel. Remove from 6.

  FIG. 17 is a perspective view of the dust box and the lifting panel after the dust box is taken out. In FIG. 17, the moving panel 6 is formed with a storage portion 6 a in which the dust box 24 is stored. When FIG. 17 is viewed from the front, the first pushing portion 90 of the take-out mechanism is arranged at the left end, and the second push-out portion 91 of the take-out mechanism is arranged at the right end. The take-out mechanism has a first pusher 90 and a second pusher 91. The first push-out unit 90 has a button 92, and when the user presses the button 92, the first push-out unit 90 pushes the vicinity of one end of the dust box 24 to the upper side of the moving panel 6, and at the same time, the second push-out unit 90 The part 91 pushes the vicinity of the other end of the dust box 24 to the upper side of the moving panel 6. When the dust box 24 is attached to the storage portion 6a, hooks (not shown) are fitted into the recesses 94 provided at both ends of the dust box 24 to prevent the dust box 24 from protruding upward.

<Release and fastening of gears for opening and closing and lifting>
FIG. 18 is a diagram for explaining the operation of the moving panel and its peripheral members when the moving panel is closed. In FIG. 18, other configurations are provided for explaining the relationship among the brush 23 attached to the dust box 24, the brush side gear 51 fixed to the rotation shaft of the brush 23, the drive side gear 54, and the intermediate transmission gear 53. Is omitted.

  The dust box 24 is rotated together with the movable panel 6 from the closed position as shown by reference numerals D1, D2 and D3 in FIG. The reference numeral D1 in FIG. 18 indicates the movable panel 6 and its peripheral members during operation, and the reference numeral D2 in FIG. 18 indicates the movable panel 6 and its peripheral members when open. What is indicated by reference numeral D3 is the movable panel 6 and its peripheral members during elevation.

  When the movable panel 6 is closed when the operation is stopped as indicated by reference numeral D <b> 1, the drive-side gear 54 meshes with the brush-side gear 51 from the lower side of the brush-side gear 51. When the air filter 20 is cleaned, a driving force can be transmitted from the intermediate transmission gear 53 to the brush side gear 51 through the driving side gear 54 and from the brush driving motor 32 shown in FIG.

  The rotation shaft 54 a of the drive side gear 54 is connected to the rotation shaft 53 a of the intermediate transmission gear 53 by a connecting member 86. Therefore, the distance between the drive-side gear 54 and the intermediate transmission gear 53 is constant, and the state where the drive-side gear 54 and the intermediate transmission gear 53 are kept engaged is always maintained. Note that the drive-side gear 54 and the intermediate transmission gear 53 that are rotatably attached to the rotary shafts 54 a and 53 a are naturally rotatable even if the rotary shafts 54 a and 53 a are attached to the connecting member 86. There is no change. The connecting member 86 is attached to the decorative panel 8 so as to be rotatable about the intermediate transmission gear 53. However, when the drive side gear 54 is engaged with the brush side gear 51, the connecting member 86 is locked so as not to rotate and is fixed to the decorative panel 1. Alternatively, when the drive side gear 54 is engaged with the brush side gear 51, the connecting member 86 is biased in a direction to press the drive side gear 54 against the brush side gear 51.

  As described above, the drive-side gear 54 meshes from below the brush-side gear 51, that is, the drive-side gear 54 is disposed on the side that prevents the brush 23 from separating with the moving panel 6. . As a result, the drive-side gear 54 restricts the movement in the direction in which the drive shaft of the brush 23 separates together with the brush-side gear 51.

  On the other hand, before the moving panel 6 is rotated or lifted as indicated by reference sign D2 or D3 in FIG. 18, the drive side gear 54 is placed on the movement trajectory of the brush side gear 51 when the moving panel 6 is turned or lifted. The connecting member 86 rotates in the direction indicated by the arrow AR1 so that is not positioned. Thereby, the drive side gear 54 does not hinder the movement of the movable panel 6. For example, the connecting member 86 is rotated by the drive side gear moving motor 33 under the control of the control device 25. The drive side gear moving motor 33 is a stepping motor, and the rotation angle of the connecting member 86 is changed by a pulse signal output from the control device 25. Therefore, after the movable panel 6 is closed and returned to the position indicated by the symbol D1, the control device 25 drives the drive-side gear moving motor 33 in order to fit the drive-side gear 54 to the brush-side gear 51 again. The connecting member 86 is rotated reversely by an angle equal to the rotated angle.

Second Embodiment
In the air conditioning indoor unit 2 according to the first embodiment, the drive side gear 54 is configured by a spur gear, but in the air conditioning indoor unit 2 according to the second embodiment, the drive side gear 87 is configured by a rack gear. The configuration other than the driving force transmission mechanism by the driving side gear 87 of the air conditioning indoor unit 2 of the second embodiment, for example, the lifting mechanism and the turning mechanism of the movable panel 6 are the same as the air conditioning indoor unit 2 of the first embodiment. Therefore, explanation is omitted.

  FIG. 19 shows the relationship among the brush 23 attached to the dust box 24, the brush side gear 51 fixed to the rotating shaft of the brush 23, the drive side gear 87, and the intermediate transmission gear 88.

  The dust box 24 is rotated together with the movable panel 6 as shown by reference numerals E1, E2, and E3 in FIG. The reference numeral E1 in FIG. 19 shows the movable panel 6 and its peripheral members during operation, and the reference numeral E2 in FIG. 19 shows the movable panel 6 and its peripheral members in the open state. The reference numeral E3 indicates the movable panel 6 and its peripheral members when moving up and down.

  When the movable panel 6 is closed when the operation is stopped as indicated by reference numeral E <b> 1, the drive side gear 87 is meshed with the brush side gear 51 from the lower side of the brush side gear 51. Accordingly, when the air filter 20 is cleaned, the driving force can be transmitted from the intermediate transmission gear 88 to the brush side gear 51 via the driving side gear 87 and from the brush driving motor 32 shown in FIG. Since the brush side gear 51 has the same number of teeth as the intermediate transmission gear 88, the driving force is transmitted by the driving side gear 87 and moves in the same manner as the intermediate transmission gear 88. The rotation of the intermediate transmission gear 88 is controlled by the control device 25, and while the brush 23 is rotated and the air filter 20 is cleaned, the state where the driving gear 87 is engaged with the brush gear 51 is maintained. Is done. Since the drive side gear 87 extends in the horizontal direction, it cannot be made too long due to the internal space of the air conditioning indoor unit 2. However, the brush 23 has a length for rotating about 3 to 5 times. Although the configuration for power transmission between the intermediate transmission gear 88 and the brush drive motor 32 is different from that of the first embodiment, the description is omitted because it is a simple design change. Although not shown, the drive side gear 87, which is a rack gear, is supported so as to maintain the horizontal position shown in FIG.

  As described above, the drive-side gear 87 meshes from the bottom of the brush-side gear 51, that is, the drive-side gear 87 is disposed on the side that prevents the brush 23 from separating with the moving panel 6. . The drive gear 87, which is a rack gear, is firmly supported so as to maintain a horizontal position, and the rack gear is a rigid body such as metal or plastic. Therefore, the movement of the brush 23 in the direction in which the drive shaft is separated from the brush side gear 51 can be regulated by the drive side gear 87.

  On the other hand, before the moving panel 6 is rotated or lifted as indicated by reference numerals E2 and E3 in FIG. 19, the drive side gear 87 is placed on the movement locus of the brush side gear 51 when the moving panel 6 is rotated or lifted. The drive side gear 87, which is a rack gear, is pulled out from the lower side of the brush side gear 51 by the intermediate transmission gear 88. This is performed by controlling the number of rotations of the intermediate transmission gear 88 by the control device 25. By pulling out from the lower side of the brush side gear 51, the driving side gear 87 does not hinder the movement of the moving panel 6. When the moving panel 6 is closed again, the intermediate transmission gear 88 is rotated in the reverse direction to return to the state shown in FIG. Control of the rotation of the intermediate transmission gear 88 that pulls out and returns the driving gear 87 is performed by controlling the brush driving motor 32 by the control device 25.

A horizontal flap 117 for guiding the air blown out from the air outlet 215 is provided at the air outlet 215 provided in the lower front portion of the bottom frame 211.

(Filter unit)
The filter unit frame 122 is provided with a grid-like opening at a portion facing the indoor heat exchanger. On the inner surface of the filter unit frame 122, as shown in FIG. 21, an upper guide portion 126, a front guide portion 127, a lower guide portion 128, and a rear guide portion are provided to guide the air filter 121 while being in contact with the air filter 121. An air filter guide 125 made of 129 is provided. The upper guide portion 126 is provided along the upper surface of the filter unit frame 122. The front guide portion 127 is provided following the upper guide portion 126 and has a shape that is gently curved along the front surface of the filter unit frame 122. The lower guide portion 128 is provided following the front guide portion 127, and is curved convexly downward so that the air filter 121 guided downward from the front guide portion 127 is U-turned again upward. It has a circular arc shape. The rear guide portion 129 is provided following the lower guide portion 128 and is gently curved along the back surface of the filter unit frame 122.

  The filter drive gear 123 is disposed above the lower guide portion 128 with a gap therebetween so that a gap through which the air filter 121 passes is provided between the filter drive gear 123 and the lower guide portion 128. The teeth of the filter drive gear 123 slip into the filter drive gear 123 and the air filter 121 when the teeth are fitted in the recesses provided continuously in the air filter 121 to apply a drive force to the air filter 121. prevent. Thereby, the air filter 121 moves along the air filter guide 125 as the filter drive gear 123 rotates.

<Brush unit>
As shown in FIGS. 22 and 23, the brush unit 170 includes a frame portion 171, a brush portion 172, a brush side gear 173, a brush cleaning portion 174, and a dust receiving portion 175. The brush unit 170 is configured to be detachable from the outside of the air conditioning indoor unit 101 without interfering with the front panel 160 when the front panel 160 is closed. The frame portion 171 has an elongated outer shape along the longitudinal direction of the air conditioning indoor unit 101. In a state where the brush unit 170 is attached to the air conditioning indoor unit 101, the brush portion 172 protruding upward from the opening 171a on the upper portion of the frame portion 171 contacts the slidable air filter 121 by the lower guide portion 128. .

  The brush unit 172 includes a rotation shaft 176, bristles 177 extending radially around the rotation shaft 176, and a brush-side gear 173. In order to clean the brush portion 172, a brush cleaning portion 174 having a plurality of comb teeth 179 is provided in contact with the brush portion 172. The dust receiving part 175 is detachably attached to the frame part 171 below the brush cleaning part 174 in order to store the dust scraped off by the brush cleaning pad 174.

  In 3rd Embodiment, the brush unit 170 except the brush part 172 comprises a dust box.

  When the brush unit 170 is fitted when the operation is stopped, the drive side gear 181 meshes with the brush side gear 173 from the lower side of the brush side gear 173. Thereby, when cleaning the air filter 121, a driving force can be transmitted from a brush drive motor (not shown) from the intermediate transmission gear 182 to the brush side gear 173 via the drive side gear 181. Since the drive side gear 181 meshes from under the brush side gear 173, the drive side gear 181 restricts the movement of the brush 172 in the direction in which the drive shaft 176 separates together with the brush side gear 173.

  The relationship between the drive side gear 181, the drive gear 181, the connecting member 190, the intermediate transmission gear 182, and the intermediate transmission gear 182 depends on the rotation of the drive side gear 54 and the drive side gear 54 of the first embodiment. Since the relationship between the shaft 54a, the connecting member 86, the intermediate transmission gear 53, and the intermediate transmission gear 53 is the same, the description thereof is omitted.

  When the brush unit 170 is removed from the air conditioning indoor unit 101 when the operation is stopped, the drive side gear 181 rotates in advance around the rotation shaft of the intermediate transmission gear 182 and is driven on the locus when the brush side gear 172 is separated. The side gear 181 is not located. Thereby, it is possible to prevent the drive gear 181 from obstructing the extraction of the brush unit 170.

<Features>
(1)
The drive side gears 54, 87, and 181 (drive side gears) of the first to third embodiments are disposed on the side opposite to the air filters 20 and 121. Therefore, the drive side gears 54, 87, and 181 are located where the brush side gears 51 and 173 (brush side gear) are prevented from separating. Thereby, the movement which the brush side gears 51 and 173 separate can be controlled.

  The brush side gears 51 and 173 (brush side gears) of the first to third embodiments are restricted from moving apart by the drive side gears 54, 87, and 181 (drive side gears). The vibration transmitted from 173 to the surroundings can be suppressed. Further, it is possible to prevent the brushes 23 and 172 and the peripheral parts from being detached together with the brushes 23 and 172.

(2)
The movement of the dust box 24 and the brush unit 170 according to the first to third embodiments to be separated from the air filters 20 and 122 can be restricted by the drive side gears 54, 87, and 181. Thereby, it is possible to prevent the dust box 24 and the brush unit 170 from pulsating and coming off. Moreover, the vibration of the movable panel 6 to which the dust box 24 is attached can be reduced. Furthermore, such movement restriction not only reduces vibration, but also serves to prevent the dust box 24 from being detached from the movable panel 6.

  The drive side gear 87 of the second embodiment can be moved to a position that does not hinder the separation of the brush side gear 51 by controlling the rotation of the intermediate transmission gear 88 and pulling it out from under the brush side gear 51. The air filters 20 and 122 can be separated smoothly.

<Modification>
(A)
In the first and third embodiments, the driving side gears 54 and 87 and the rotation shafts 54a and 53a of the intermediate transmission gears 53 and 88 are connected by the connecting member 86. However, the driving side gears 54 and 87 are independently used. It may be moved to a position that does not hinder the separation of the brush side gear 51.

(B)
In the first to third embodiments, the drive side gears include the drive side gears 54 and 181 that are spur gears and the drive side gear 87 that is a rack gear. However, other types of gears may be used.

(C)
In 1st thru | or 3rd Embodiment, although the case where the brush side gears 51 and 173 (brush side gear) were fixed to the rotating shaft of the brushes 23 and 172 was demonstrated, it is not restricted to what is fixed to the rotating shaft. For example, an intermediate transmission gear may be provided between the gear fixed to the rotating shaft and the drive side gears 54, 87, 181. If the intermediate transmission gear is separated from the air filters 20 and 122 together with the brushes 23 and 172, the same effect as in the above embodiment is obtained.
