When the roller 102 rotates, rotation is transmitted from the pinion gear 102 a to the rack 101, and the rack 101 of the filter 9 is conveyed by the roller 102 to the rear storage path 106 a side. As the roller 102 continues to rotate, the first end of the rack 101 reaches the end of the rear storage path 106a.

  When the first end of the rack 101 reaches the end of the rear storage path 106a, the first end turns the lever of the position detection switch 107 (see FIG. 3) to turn it on. The control unit determines that the first end portion of the rack 101 has reached the end of the rear storage path 106a from the ON signal output from the position detection switch 107, and stops the rotation of the roller 102. At this time, the entire region of the rack 101 of the filter 9 is accommodated in the rear storage path 106a, and the other end of the rack 101 (hereinafter referred to as the second end) is engaged with the pinion gear 102a.

  In FIG. 5, when the filter 9 moves, dust attached to the surface of the filter 9 is scraped off by the brush 108. The brush 108 rotates at least during the period when the filter 9 is moving from the front storage path 105 a to the rear storage path 106 a, and the rotation direction is a direction opposite to the traveling direction of the filter 9.

  When the filter 9 moves from the front storage path 105a to the rear storage path 106a and the dust removal is completed, the control unit rotates the roller 102 in the reverse direction. Since the second end portion of the rack 101 of the filter 9 meshes with the pinion gear 102 a, rotation is transmitted from the pinion gear 102 a to the rack 101, and the filter 9 is conveyed to the front storage path 105 a side by the roller 102. As the roller 102 continues to rotate in the reverse direction, the second end of the rack 101 reaches the end of the front storage path 105a.

  When the second end of the rack 101 reaches the end of the front storage path 105a, the second end turns the lever of the position detection switch 107 to turn it on. The control unit determines that the second end of the rack 101 has reached the end of the front storage path 105a from the ON signal output from the position detection switch 107, and stops the rotation of the roller 102. At this time, the rack 101 of the filter 9 is accommodated in the front storage path 105a, and the first end of the rack 101 is engaged with the pinion gear 102a.

(Movable panel 24)
FIG. 6 is a perspective view of a movable panel suspended from a wire. In FIG. 6, the movable panel 24 has a resin panel body 241 and a resin panel cover 247. The panel cover 247 is a member that covers the upper surface of the panel main body 241, and the dust box 109 is disposed on the upper surface of the panel main body 241, and the hanging portions 242 to which the wires 71 are connected are disposed near both ends of the upper surface. Therefore, the panel cover 247 covers the upper surface of the panel main body 241 so as to avoid the dust box 109 and the hanging portion 242.

  FIG. 7 is a cross-sectional view of the movable panel taken along line AA in FIG. In FIG. 7, a claw 241 a that protrudes upward is formed on the edge of the panel body 241, and a claw receiver 247 a that receives the claw 241 a is formed on the edge of the panel cover 247. When the panel cover 247 and the panel cover 247 are overlapped, the claw 241a is fitted into the claw receiver 247a and positioned. The front end portion of the claw 241a is formed in a convex shape toward the inside of the panel body 241, and the claw receiver 247a is formed in a concave shape so as to receive the convex portion of the claw 241a. And the concave portion of the claw receiver 247a mesh with each other so that they are not easily separated.

  In addition, a plurality of screw receiving projections 243 projecting upward are provided on the upper surface of the panel body 241. The screw receiving protrusion 243 is screwed to the metal reinforcing member 246. The reinforcing member 246 has a U-shaped cross section, and is screwed after being disposed so that the concave portion covers the screw receiving protrusion 243. Since the panel cover 247 covers the upper surface of the panel main body 241 so as to hide the reinforcing member 246, a hollow space is formed between the panel main body 241 and the panel cover 247. As a result, the thickness of the movable panel 24 increases, and the three-dimensional effect of the movable panel 24 is emphasized. For convenience of explanation, the side where the thickness of the movable panel 24 is thin is defined as the front, and the opposite side is defined as the rear.

  FIG. 8 is a plan view of the panel body. 7, the side on which the thickness of the movable panel 24 is thin is defined as the front side. Therefore, the upper side in plan view is the front side of the panel body 241 in FIG. 8. 7 and 8, the screw receiving projections 243 are provided on both the front side and the rear side of the panel main body 241, and as shown in FIG. The protrusions 243 are arranged, and seven screw receiving protrusions 243 are arranged on the rear side of the panel main body 241. And the rib 244 is provided so that the screw | thread receiving protrusion 243 may be connected.

  FIG. 9A is a cross-sectional view of the movable panel taken along line BB in FIG. 7 before the reinforcing member is screwed, and FIG. 9B is a diagram of FIG. 7 after the reinforcing member is screwed. It is sectional drawing of the movable panel in the BB line. As shown in FIG. 9A, among the screw receiving protrusions 243, the height of the central screw receiving protrusion 243a is set lower than the adjacent screw receiving protrusions 243b and 243c. As a result, when the screw receiving protrusions 243a, 243b, 243c and the reinforcing member 246 are screwed with the screw 249, the metal reinforcing member 246 has a higher rigidity than the resin panel main body 241, so that FIG. ), The center portion of the panel body 241 is bent so as to protrude upward. This bend is offset (cancelled) when the panel body 241 is hung by the wire 71 and the center part far from the hanging part 242 is warped downward by its own weight. Is realized.

  FIG. 10 is a rear view of the panel cover. Note that, in FIG. 7, the side on which the thickness of the movable panel 24 is thin is defined as the front, and therefore, the upper side in plan view is the front of the panel cover 247 in FIG. 10.

  In FIG. 10, the panel cover 247 is provided with a large square hole 247b, a small square hole 247c, and a rib 247d. The large square hole 247b and the small square hole 247c are provided to avoid interference with the dust box 109 and the suspension portion 242 disposed on the upper surface of the panel body 241 when the panel cover 247 covers the upper surface of the panel body 241. ing. The ribs 247d are provided in a lattice shape to reinforce the panel cover 247.

  When the panel cover 247 covers the upper surface of the panel main body 241, the screw receiving projections 243, the ribs 244, and the reinforcing member 246 are not exposed to the outside, so that there is no resistance to the air sucked into the suction port 20a. Disturbance is less likely to occur.

<Apparatus related to operation of movable panel 24>
(Elevating device 7)
FIG. 11 is a layout view of components inside the lifting device. In FIG. 11, the lifting device 7 is a device that feeds out or winds up the wire 71. When the lifting device 7 feeds the wire 71, the lifting motor 76 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 71.

  On the other hand, when the lifting device 7 winds the wire 71, the lifting motor 76 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 71. The feeding amount and winding amount of the wire 71 are proportional to the rotation amount of the lifting motor 76, and the control unit controls the number of pulses supplied to the lifting motor 76, whereby the feeding amount and winding amount of the wire 71 are controlled. Is controlled.

  Since the movable panel 24 is connected to the tip of the wire 71, tension is always generated in the wire 71, and when the wire 71 is drawn out or wound up, the pulley portion 72a is connected to the wire 71. It is rotated by the frictional force. At this time, since the cam portion 72b also rotates, the switch 77 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 unit.

  However, if the wire 71 loses the slack tension due to some reason, for example, when the movable panel 24 is lowered by feeding the wire 71 for maintenance, the movable panel 24 is moved before reaching the predetermined feeding amount. When landing on a table or the like and stopping, the frictional force between the wire 71 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 77. At this time, since the signal from the switch 77 is constant when the lifting motor 76 is rotating, the control unit estimates that the movable panel 24 has stopped due to some obstacle, and immediately moves the lifting motor 76. Stop.

(Hinge 530)
12 is a perspective view of the movable panel, and FIG. 13 is an enlarged view of a portion C in FIG. In FIG. 12, the movable panel 24 is rotatably supported by the main body 20 (see FIG. 3) by a hinge 530. As shown in FIG. 13, the hinge 530 includes a horizontal bar portion 531 extending in the horizontal direction, a lever 532 extending vertically from the horizontal bar portion 531, and a hook 533 that bends in a hook shape from the end of the lever 532. It is stationary with the bar 531 facing up.

  FIG. 14 is a side view of a single hinge. In FIG. 14, the hinge 530 further includes a rotation shaft portion 534 serving as a rotation center of the movable panel 24. The hinge 530 is subjected to a spring force so as to fall in the direction D by a spring in the movable panel 24.

It is a fragmentary sectional view of a lower part of a main part. In FIG. 15A, in a space below the horizontal bar portion 531 of the hinge 530, a hinge receiver 761 that receives the horizontal bar portion 531 and a protrusion 763 that contacts the hook 533 (see FIG. 14) protrude from the main body 20 side. ing. When the movable panel 24 closes the suction port 20a, the hook 533 comes into contact with the protrusion 763, so that the horizontal bar portion 531 is stationary in a state of being rotated clockwise around the rotation shaft portion 534. ing. At this time, the horizontal bar portion 531 and the hinge receiver 761 are not yet in contact with each other.

  In FIG. 15B, when the movable panel 24 is lowered, the horizontal bar portion 531 is caught by the hinge receiver 761 and stopped.

FIG. In FIG. 16A, in a space below the horizontal bar portion 531 of the hinge 530, a hinge receiver 761 that receives the horizontal bar portion 531 and a protrusion 763 that contacts the hook 533 (see FIG. 14) protrude from the main body 20 side. ing. When the movable panel 24 closes the suction port 20a, the hook 533 comes into contact with the protrusion 763, so that the horizontal bar portion 531 is stationary in a state of being rotated clockwise around the rotation shaft portion 534. ing. At this time, the horizontal bar portion 531 and the hinge receiver 761 are not yet in contact with each other.

  16 (b) and 16 (c), the hinge receiver 761 is pushed by another member (not shown) and is off the descending orbit of the hinge 530. When the hinge 530 is lowered, both ends of the horizontal bar portion 531 are The movable panel 24 can be lowered without rotating without being held by the hinge receiver 761.

  On the other hand, the operation when the movable panel 24 closes the suction port 20a is opposite to the operation when the suction port 20a is opened. By raising the movable panel 24, the state shown in FIG. After the state, the state (c) is obtained.

<Features>
In the movable panel 24 of the air conditioning indoor unit 2, the upper surface of the panel main body 241 is covered with the panel cover 247 so that the unevenness including the reinforcing rib 244 and the reinforcing member 246 is not exposed to the outside. As a result, air flowing into the suction port 20a flows along the smooth surface of the panel cover 247, so that the turbulence of the airflow is suppressed.

  Moreover, since the hollow structure is formed by the panel main body 241 and the panel cover 247, the thickness of the movable panel 24 increases, a three-dimensional effect is emphasized, and design property improves. Furthermore, since the claw receiver 247a into which the claw 241a and the claw 241a are fitted is formed between the panel main body 241 and the panel cover 247, the panel main body 241 and the panel cover 247 can be easily assembled and workability is improved. To do.
