  Next, the configuration of the automatic cleaning means 7 will be described with reference to FIGS. 4 and 5. FIG. 4 is a schematic perspective view showing the configuration of the rotating member, and FIG. 5 is a schematic perspective view showing the configuration of the cleaning arm.
  As shown in FIG. 4, the first cleaning means 11 for cleaning a part of the pre-filter 4 and the second cleaning means 12 for cleaning the remaining part of the pre-filter 4 are provided in the rotating member 13, and as shown in FIG. The rotating member 13 is rotatably supported by the rotating member frame 14. Returning to FIG. 4, the rotating member 13 is formed in a substantially bowl shape, and the first cleaning means 11 and the second cleaning means 12 are provided on the side surface in the longitudinal direction. The shape of the rotating member 13 may be a substantially cylindrical shape or a substantially semi-cylindrical shape.
  The lengths of the first cleaning means 11 and the second cleaning means 12 (referring to the length in the same direction as the longitudinal direction of the rotating member) are the first cleaning means indicated by the arrow 15 in FIG. 11 and the length of the second cleaning means 12 indicated by the arrow 16 are arranged at predetermined lengths such that the sum of the length of the second cleaning means 12 indicated by the arrow 16 is equal to or greater than the length of the rotating member 13 indicated by the arrow 17. ing. However, the lengths of the first cleaning means 11 and the second cleaning means 12 are arranged to be shorter than the length in the longitudinal direction of the rotating member 13.

  As shown in FIG. 5, the rotating member frame 14 is detachably disposed with respect to a cleaning arm 18 that moves on the surface of the prefilter 4 in the vertical direction.
  Although the cleaning arm 18 returns to FIG. 3, when the automatic cleaning operation is not in operation, the cleaning arm 18 is stationary at a stationary position 19 provided above the prefilter 4 of the main body case 1 (broken line portion). A driving means 20 constituted by an electric motor or a combination gear is disposed in the main body case 1, and the cleaning arm 18 can be moved in the vertical direction of the pre-filter 4.
Further, a dust box 21 as a storage means for storing coarse dust and dust removed from the pre-filter 4 is detachably provided at the lower part of the main body case 1.
  Next, the configuration of the switching unit 22 that switches the cleaning unit that contacts the pre-filter 4 by rotating the rotating member 13 between the first cleaning unit 11 and the second cleaning unit 12 will be described with reference to FIG. To do. FIG. 6 is a side sectional view showing the configuration of the rotating member 13.
  The switching means 22 includes a first cleaning means 11 and a second cleaning means 12 arranged at a predetermined angle with respect to the rotation direction of the rotating member 13 indicated by an arrow 23 in FIG. A plurality of protrusions 24 are formed as stoppers that define the rotation angle of the rotating member 13 by contacting the rotating member frame 14.
  The first cleaning means 11 and the second cleaning means 12 are such that when the cleaning arm 18 moves in the forward path, the first cleaning means 11 contacts the prefilter 4 and when the cleaning arm 18 moves in the backward path, the second cleaning means 12 4 is arranged at an angle contacting 4. The angle shown here is an angle formed by the first cleaning unit 11 and the second cleaning unit 12 around the rotation axis of the rotating member 13.
  Hereinafter, the operation will be described with reference to FIGS. 3, 7A and 7B. FIG. 7A is a schematic cross-sectional view showing the operation of the rotating member 13 when the moving direction of the cleaning arm 18 is changed from below to above, and FIG. 7B is the direction of movement of the cleaning arm 18 from above to below. It is a schematic sectional drawing which shows operation | movement of the rotating member 13 at the time of a change.
When the automatic cleaning operation starts, as shown in FIG. 3, the cleaning arm 18 starts to move downward from the stationary position 19 by the action of the driving means 20, and the first cleaning provided in the rotating member 13 included in the cleaning arm 18. The means 11 moves from the upper end to the lower end of the prefilter 4 while sliding a part of the prefilter 4, and removes coarse dust and dust adhering to the surface of the prefilter 4 from the prefilter 4. The coarse dust and dust removed from the prefilter 4 falls into a dust box 21 provided below the main body and is stored. Then, when the first cleaning means 11 reaches the lower end of the pre-filter 4, the traveling direction of the cleaning arm 18 is reversed by the action of the driving means 20, and starts to move upward. A path from the stationary position 19 to the lower end of the pre-filter 4 is defined as a forward path.
  At this time, as shown in FIG. 7A, the rotating member 13 pivotally supported on the rotating member frame 14 of the cleaning arm 18 has a frictional force between the first cleaning means 11 and the prefilter 4. Rotate in the direction indicated by arrow 25. And the protrusion part 24 as a stopper formed in the rotation member 13 contacts the rotation member frame 14, and the rotation member 13 does not rotate any more. At this time, since the first cleaning means 11 and the second cleaning means 12 are arranged at a predetermined angle, the rotation of the rotating member 13 is performed at a position where the second cleaning means 12 is just in contact with the prefilter 4. It will stop.
When the cleaning arm 18 starts to move upward, the second cleaning means 12 that is in contact with the prefilter 4 slides on the remaining portion of the prefilter 4, that is, the portion that the first cleaning means 11 is not cleaning. It moves from the lower side of the prefilter 4 to the upper side, reaches the stationary position 19 while removing the coarse dust and dust adhering to the surface of the prefilter 4 and stops still. A path from the lower end of the prefilter 4 to the stationary position 19 is defined as a return path. The coarse dust and dust removed from the prefilter 4 falls into the dust box 21 and is stored.
  When the air cleaning operation for a predetermined time elapses, the automatic cleaning means starts operating again, and the cleaning arm 18 starts to move downward. At this time, as shown in FIG. 7B, the rotating member 13 rotates in the direction indicated by the arrow 26 by the frictional force acting between the second cleaning means 12 and the pre-filter 4. And the protrusion part 24 as a stopper formed in the rotation member 13 contacts the rotation member frame 14, and the rotation member 13 does not rotate any more. At this time, since the first cleaning means 11 and the second cleaning means 12 are arranged at a predetermined angle, the rotation of the rotating member 13 stops at the position where the first cleaning means 11 just contacts the prefilter 4. become. In the same manner as described above, the cleaning arm 18 moves from the upper side to the lower side of the prefilter 4 so that the prefilter 4 can be cleaned.
Here, when the pre-filter 4 is cleaned from the upper side to the lower side by the automatic cleaning means, the conventional brush rotates as the cleaning means and slides on the surface of the pre-filter 4 so that coarse dust and dust are collected. Was to be removed. The rotating brush 102 moves while cleaning the entire surface of the prefilter 4 from above to below. Therefore, since the entire surface of the pre-filter 4 is cleaned at a time, the contact area between the rotary brush 102 and the pre-filter 4 is large, and the frictional resistance applied to the rotary brush 102 increases. The driving load applied to the driving means 105 to be moved was large.
  As described above, the present invention assigns the area to be cleaned of the prefilter 4 to the first cleaning means 11 and the second cleaning means 12, that is, a part of the prefilter 4 in the forward path (the right half in FIG. 3). The remaining part of the pre-filter 4 on the return path, that is, the portion not cleaned on the forward path (the left half in FIG. 3) is cleaned, so that the area where the cleaning means and the pre-filter 4 come into contact can be reduced. . Therefore, since the frictional resistance with the pre-filter 4 per cleaning means is less than that of the conventional method, the load on the driving means 20 for moving the cleaning arm 18 can be reduced.
  Therefore, power consumption for automatic cleaning can be reduced, and a small and inexpensive driving means with a small torque can be used.
  The automatic cleaning means 7 has a switching means for switching between the first cleaning means 11 for cleaning on the forward path and the second cleaning means 12 for cleaning on the return path. As described above, the switching means is an operation for cleaning the prefilter 4. A structure that can be automatically and sequentially switched with a change in direction, that is, when the traveling direction of the cleaning arm 18 is switched, the rotating member 13 is rotated by friction between the first cleaning means 11 and the second cleaning means 12 and the prefilter 4. Since the switching action is performed, no other power unit is required for switching the cleaning unit, and the configuration of the main body can be simplified.
  With the above-described configuration and operational effects, the air purifying apparatus according to Embodiment 1 of the present invention can achieve the intended purpose.
  In this embodiment, the case where there are two cleaning units has been described. However, three or more cleaning units may be provided, and a plurality of cleaning units are sequentially switched by the switching unit as described above. The same effect can be obtained.
