  For example, as shown in FIG. 8, the conventional air conditioner is provided with a suction port 41 on the upper surface of the main body 40, and a blower outlet 42 provided with a wind direction deflecting plate on the front part of the lower surface, and the suction port 41 and the blower outlet 42. A heat exchanger 43 formed of a front heat exchanger and a rear heat exchanger in an air passage connecting the two and a reverse V-shaped air blower that sends air heat-exchanged by the heat exchanger 43 into the room A fan 44 is provided.

  A filter 45 that adsorbs dust contained in the sucked air is slidably and detachably mounted on the back surface of the suction port 41, and the filter 45 passes through the front portion of the main body 40. A dust box 46 composed of an upper box and a lower box, provided with front and rear passages, is provided. The dust box 46 is provided with a brush 47, a gear 49, and a drive motor 48 for driving the gear 49, and provided with a rack that meshes with the gear 49 when the gear 49 is rotated by the drive motor 48. The filter 45 moves back and forth. When dust accumulates on the surface, the drive motor 48 pulls the filter 45 forward of the main body 40. The accumulated dust is captured and collected by the brush 47 and stored in the dust box 46. Thereafter, the drive motor 48 is rotated in the reverse direction and the filter 45 is stored again on the back surface of the suction port 41. When dust accumulates in the dust box 46, the dust box 46 is removed from the main body 40, the upper box is removed from the lower box, and the dust is discarded to the outside. Thereafter, the dust box 46 is assembled and stored in the main body 40 again.

  However, when separating the dust box 46 from the upper box into the lower box, there is a risk that the dust box may be accidentally scattered around or attached to clothes, and there is a need for countermeasures. .

These rear ends are joined by a support shaft 11f as shown in FIG. 4B, and can be opened and closed with the support shaft 11f as an axis. In addition, a rectangular rear passage port 11c through which the filter 10 passes is formed at the joint portion of the rear edge of the upper box 11a and the lower box 11b, and a slit-like front portion is similarly formed at the joint front edge. A part passage opening 11d is formed. A first brush 14 is pivotally supported on the rear passage port 11c side of the upper box 11a, and a second brush 16 is provided on the front passage port 11d side. As shown in FIG. 4 (B), the lower box 11b is formed with a rectangular opening hole facing the gear provided in the driving device 22 on the bottom surface of the center, and is divided into the opening holes. A pair of left and right third brushes 13a is provided on the front passage opening 11d side, and a pair of left and right fourth brushes 12a in which a large number of brushes are implanted are provided on the rear passage opening 11c side.

  The drive device 22 is engaged with a drive motor having a pinion gear fitted to a rotation shaft, a large-diameter gear meshed with the pinion gear, and the gear 10 and meshed with a rack 10c formed in the filter 10. It is comprised from the gearwheel which faces the open port of the lower box 11b.

  Further, the structure of the dust box 11 will be described in detail. As shown in FIG. 4B, on both sides of the upper box 11b, there are formed side plates 11e hanging downward with a rectangular locking hole 11g, and on both sides of the rear of the lower box 11b. The side plate 11h provided with a bearing portion that pivotally supports the shaft 11f that protrudes from the side plate 11e extends upward, and the recesses on both sides of the lower portion engage with the locking holes 11g. The pawl 11j protrudes from the left and right so that it can be freely engaged and disengaged. The upper box 11a has a front edge formed with a handle portion 11k projecting so as to be inclined, and can be easily opened and closed by the handle portion 11k.

  As shown in FIG. 5, a stepped portion is formed at the center and the front of the lower box 11 b, and the fourth brush 12 a with a large number of flocks is provided at the center stepped portion 12. The part 13 is provided with the knitted third brush 13a for preventing dust from diffusing outside the dust box 11. At the front of the upper box 11a, a substantially flat second holder 16a having a stepped portion rotatably supported by a shaft 16b pivotally supported by a rib projecting from the inner wall, and the second holder 16a A second brush 16 comprising a thin brush 18 and a thick brush 17 attached to the front and rear surfaces is provided, and the second brush 16 is a pair of bosses 19 projecting from the inner wall surface of the upper box 11a. When the filter 10 passes through the dust box 11 by the spring 20 fitted between the holder 16a and the shaft 16b, the dust accumulated on the upper surface thereof is efficiently removed. It is supposed to be removed. The tip of the second holder 16a is bent upward in an arc shape to form a second guide portion 16c, and the second guide portion 16c is re-attached to the filter 10 pulled out to the front side. When housed in the body, the filter 10 is smoothly guided into the dust box 11 even if the filter 10 is deformed or distorted, for example.

  At the rear of the upper box 11a, there are a rotating shaft 14b rotatably supported by a rib projecting from the inner wall, a curved first holder 14a integrally connected to the rotating shaft 14b, and the same. A first brush 14 comprising a brush 14c attached to the lower surface of the first holder 14a is provided, and the tip of the first holder 14a is moved downward by a coiled spring wound around one end of the rotating shaft 14b. It is urged to go to. A plurality of first guide portions 14d, which are formed at an acute angle at the front end portion of the first holder 14a formed in a curved shape and have a vertically long projection at the center portion, are provided at equal intervals. Similarly to the second guide portion 16c, the portion 14c smoothly guides the filter 10 to the passage port 11c when the filter 10 is housed in the main body again. The lower box 11b is provided with a fifth brush 15 so as to face the first brush 14.

  In the upper box 11a, as shown in FIG. 6, a pair of left and right viewing windows 22 are provided at the center, and suction holes 23 are provided near both sides. As shown in FIG. 7A, the suction hole 23 includes an opening / closing lid 23a rotatably supported by a shaft 23b provided on one side, and a rectangular suction hole is formed by opening the opening / closing lid 23a. 23 is opened, and the dust stored in the dust box 11 can be sucked by the vacuum cleaner. As shown in FIG. 7 (B), the viewing window 22 has a transparent glass body 22a fitted therein or integrally formed, and the amount of dust stored in the dust box 11 can be checked or a vacuum cleaner can be used. When sucking dust, the internal cleanliness can be confirmed.

  The air conditioning operation is performed for a certain period, and when dust accumulates on the front and back surfaces of the filter 10, the driving device 22 is driven to reciprocate the filter 10 in the dust box 11, and the above-described brush group Remove adhering dust. Since the removed dust is gradually accumulated in the dust box 11, it is also discharged outside after a certain period. When the dust is discharged to the outside, as described above, the opening / closing lid 23a provided on the upper surface of the dust box 11 is opened, and the suction port of the vacuum cleaner is opposed to the suction hole 23 to suck the dust inside. Since the opening / closing lid 23 is provided in a pair on the left and right, half of the accumulated dust is discharged to the outside. As for the cleaning state in the dust box 11, the inside is visually confirmed from the viewing window 22, and when the completion state is confirmed, the opening / closing lid 23 is closed.

  As mentioned above, dust accumulated inside can be discharged to the outside using a vacuum cleaner, etc. without separating or disassembling the dust box. In addition to being easy to use, it is possible to improve hygiene as well as to prevent problems such as letting go.
