Description

  The present invention is equipped with a filter device, in particular, a filter device that automatically removes dust, dust, lint, etc. (collectively referred to as “dust” in the present invention) trapped in the filter, and such a filter device. It relates to air conditioners.

  2. Description of the Related Art Conventionally, an air conditioner having a filter device function capable of removing dust attached to a filter by moving the filter and easily collecting the removed dust has been disclosed (for example, see Patent Document 1). .

JP 2004-28487 A (page 5-8, FIG. 1)

However, the air conditioner disclosed in Patent Document 1 has the following problems.
(A) Since the filter moving mechanism in the filter cleaning unit includes a rack formed at the center in the width direction of the filter, a pinion that rotates in mesh with the rack, and a drive motor that rotates the pinion. If multiple filters (same for multiple filter cleaning units) are installed in the air conditioner, the drive motor will become more than one, resulting in increased manufacturing costs, increased equipment weight, and an air conditioner equipped with this. The product becomes less competitive as it increases size and restricts design.
(Ii) The filter in the filter cleaning unit is pushed out of the machine while pushing up the open / close panel provided on the front panel of the air conditioner during cleaning, that is, the filter is visually recognized from the inside. As a result, the cleanliness of the device is impaired and the occupants may feel uncomfortable and the competitiveness of the product is reduced.

  The present invention has been made in view of the above, and even if a plurality of filters are installed in the air conditioner, it is possible to prevent an increase in the number of drive motors and to reduce the amount of movement of the filter during cleaning by approximately half. An object of the present invention is to provide a filter device that can be used, and an air conditioner that can be cleaned while the filter is hidden in the machine.

The filter device according to the present invention has a front cleaning block and a rear cleaning block that are selectively driven by a two-option rotary drive unit,
The pre-cleaning block includes a pre-filter for capturing atmospheric dust;
A through hole through which the front filter is movably penetrated is formed, and a front part of the box that constitutes a part of a dust box that can store and discharge dust, and
A pre-rotation comprising a front rotation transmission portion rotatably installed at the front portion of the box and a front translation follower formed on the front filter, and rotating the front rotation transmission portion to translate the front filter A translation conversion mechanism;
A front brush that is installed in the front portion of the box and scrapes off dust trapped in the front filter;
The post-cleaning block captures dust in the atmosphere, and a post-filter;
A through hole through which the rear filter is movably penetrated is formed, and a box rear portion constituting a part of the dust box;
A post-rotation that includes a rear rotation transmission portion rotatably installed at the rear portion of the box and a rear translation follower formed on the rear filter, and rotates the rear rotation transmission portion to translate the rear filter. A translation conversion mechanism;
A rear brush installed at the rear part of the box and scraping off dust trapped by the rear filter;
The two-option rotation drive unit selects either the front rotation transmission unit of the front rotation translation conversion mechanism included in the front cleaning block or the rear rotation transmission unit of the rear rotation translation conversion mechanism included in the rear cleaning block. And rotating the selected one.

Therefore, since the filter device according to the present invention includes the front filter and the rear filter, the amount of movement when cleaning each filter can be reduced to approximately half compared to the case of a single-sheet filter. In addition, since a two-option rotation drive unit is provided, it is not necessary to install a drive motor for each of the front filter and the rear filter. In the present invention, the drive motor is not limited to an electric motor, but includes various actuators that output rotational force.
Furthermore, since the air conditioner according to the present invention is equipped with the filter device, it is lightweight, small, and has a high degree of design freedom. Further, even during cleaning, the filter only translates the interior of the air conditioner. Since it cannot be visually recognized (hidden), the design is improved, the cleanliness of the apparatus is increased, and the product competitiveness is improved.

Hereinafter, as a first embodiment, a filter device (having two cleaning units) according to an embodiment of the present invention,
As a second embodiment, a filter device (having a tandem arrangement of two cleaning units) according to an embodiment of the present invention,
As a third embodiment, a filter device (having a tandem arrangement of a single-sheet cleaning unit) according to an embodiment of the present invention,
As Embodiment 4, an air conditioner (equipped with a filter device in which two cleaning units are arranged in tandem) according to an embodiment of the present invention will be described.
In the following drawings, the same or corresponding portions are denoted by the same reference numerals, and a part of the description is omitted.

[Embodiment 1]
(Filter device: Two-sheet type)
1 to 4 show a filter device according to Embodiment 1 of the present invention. FIG. 1 (a) is a side cross-sectional view at the center in the width direction, and FIG. 1 (b) is at the end in the width direction. FIG. 2 is a perspective view as seen from the front, FIG. 3 is a perspective view as seen from the rear, and FIG. 4 is a perspective view showing the respective components by disassembling the filter device.
For convenience of explanation, the wind path formed in the filter device is referred to as “front”, “behind” in the leeward direction, “up” in the direction perpendicular to the wind path, and “down” in the other direction. In (a) and (b), the left side is “front”, the right side is “rear”, the upper side is “upper”, and the lower side is “lower”. In addition, when describing the same content with respect to the same part or a corresponding part, the subscripts “a, b” may be omitted.

(overall structure)
1 to 4, the filter device 1000 includes a two-option rotation drive unit (not shown), and a front cleaning block 100 and a rear cleaning block 200 that are selectively driven by the two-option rotation drive unit. Yes. The two-cleaning unit 300 is formed by the front cleaning block 100 and the rear cleaning block 200.
At this time, the box front portion 10 in which the constituent members constituting the front cleaning block 100 are installed or stored and the box rear portion 90 in which the constituent members constituting the rear cleaning block 200 are installed or stored are combined. The box formed by the above (six surfaces are substantially closed) may be referred to as “upper dust box 319” for convenience.
Hereinafter, each constituent member constituting the two-sheet cleaning unit 300 will be described, and the two-option rotation drive unit will be separately described in the second embodiment.

(Previous cleaning block)
The front cleaning block 100 includes a box front portion 10, a front filter 20, a front rotation translation conversion mechanism 30, and a front brush 40 from the front to the rear (accurately back and forth). Each will be described below.

(Box front)
The box front portion 10 forms a dust box 319 together with a box rear portion 90, which will be described later, and includes a pair of front box side portions 11a and 11b and a front box connecting beam 12 that connects the front box side portions 11a and 11b. Front frame 14, front cover 14 that opens and closes the front surface across the front box side portions 11 a and 11 b, and a frame or lattice front brush support installed on the rear surface across the front box side portions 11 a and 11 b 15.

The front cover 14 is detachably and pivotally installed near the lower edges of the front box side portions 11a and 11b by a hinge mechanism, and the front brush support 15 is disposed in the front-rear direction near the upper edges of the front box side portions 11a and 11b. The hinge mechanism is provided with a gap in the front and rear, and is movable in the front-rear direction, detachable and rotatable. Accordingly, the front cover 14 opens in a V shape with respect to the front box side portions 11a and 11b, and the front brush support 15 opens in an inverted V shape with respect to the front box side portions 11a and 11b. The three members have a substantially inverted N-shape and eventually become substantially planar.
That is, the dust stored in the box front portion 10 can be easily discharged (same as collecting) by opening the front cover 14 and the front brush support 15.

On the other hand, when the front cover 14 and the front brush support 15 are closed, the gap between the upper edge portion of the front cover 14 and the upper edge portion of the front brush support 15, and the lower edge portion of the front cover 14 and the lower edge of the front brush support 15. The gaps with the respective portions form through holes through which the front filter 20 penetrates (movable in the vertical direction).
Further, through holes 16a and 16b are formed in the vicinity of the lower edges of the front box side portions 11a and 11b, and this constitutes a part of a hinge mechanism in which the box rear portion 90 is detachably and rotatably locked. . Further, front shaft rotation support portions 17a and 17b are provided at substantially the center of the front box side portions 11a and 11b, and this rotatably supports the front shaft 31 constituting the front rotation translation conversion mechanism 30.

(Pre-filter)
The front filter 20 is a rectangular plate member having a ventilation portion 21 formed with a predetermined gap (not shown) through which the atmosphere can pass and dust in the atmosphere can be captured, and has flexibility. . Further, front translation portions (specifically, “rack”, hereinafter referred to as “front rack”) 22 a and 22 b constituting the front rotation translation conversion mechanism 30 are provided on the rear surfaces of the front filter 20 at both edges in the width direction. (Same on the leeward side).
Therefore, since dust is usually captured by the front surface of the front filter 20 (same as the windward surface), the dust scraped off from the front filter 20 is prevented from adhering to the racks 22a and 22b.

(Pre-rotation translation conversion mechanism)
The front rotation transmission unit constituting the front rotation translation conversion mechanism 30 includes a front shaft 31, front pinions 32a and 32b, and a front driven gear 33b. That is, the front shaft 31 is rotatably supported by the front box side portions 11 a and 11 b of the box front portion 10. The front pinions 32a and 32b are fixed to the front shaft 31 and mesh with the front racks 22a and 22b (formed on the front filter 20), respectively. The front driven gear 33b is fixed to the front box side portion 11b (right side in the drawing) of the front shaft 31, and is selectively driven to rotate by the two-option rotary drive unit.
That is, the front rotation translation conversion mechanism 30 has a rack / pinion mechanism including a front rack 22a and a front pinion 32a, and a rack / pinion mechanism including a front rack 22b and a front pinion 32b. Therefore, the filter 20 is reliably translated by rotating the front driven gear 33b. At this time, since the filter 20 receives force at both edges, the filter is not twisted (for example, deformed into a parallelogram).

(Front brush)
The front brush 40 slides on the ventilation portion 21 of the front filter 20 when the front filter 20 translates, and scrapes off the trapped dust.
That is, the pair of front upper brushes 41 and 42 installed on the upper edge portion of the front cover 14 and the upper edge portion of the front brush support 15 hold the front filter 20 with a predetermined force. At this time, the tips of the front upper brushes 41 and 42 are all inclined downward (the fibers are lying on the center side of the dust box 319). For this reason, when the front filter 20 translates upward, that is, when the front filter 20 is pushed out from the box front portion 10 (the same as pushing out from the dust box 319), the dust trapped in the front filter 20 moves downward. Since the dust is scraped off, the dust is stored in the dust box 319.

  On the contrary, when the front filter 20 translates downward, that is, when the front filter 20 is pulled into the box front portion 10 (the same as when the front filter 20 is pulled into the dust box 319), the dust trapped in the front filter 20 is scraped off. As a result, dust does not dissipate out of the dust box 319.

  On the other hand, the pair of front lower brushes 43 and 44 installed on the lower edge portion of the front cover 14 and the lower edge portion of the front brush support 15 hold the front filter 20 with a predetermined force. At this time, the tip of each of the front lower brushes 43 and 44 is such that the fibers that are inclined upward fall on the center side of the dust box 319). For this reason, when the front filter 20 translates upward, that is, when the front filter 20 is pulled into the box front portion 10 (the same as when the front filter 20 is pulled into the dust box 319), the dust captured by the front filter 20 is not scraped off. Therefore, the dust does not dissipate out of the dust box 319.

On the contrary, when the front filter 20 translates downward, that is, when the front filter 20 is pushed out of the box front portion 10 (same as pushed out of the dust box 319), the dust trapped in the front filter 20 is upward. Therefore, the dust is stored in the dust box 319.
In the present invention, the brush 40 is not literally limited to a brush, and may be felt, nonwoven fabric, or the like. At this time, for example, if the fibers are fluffed according to the above, dust can be scraped off only for sliding in the one direction.

(After cleaning block)
The rear cleaning block 200 has a rear brush 60, a rear filter 70, a rear rotation translation conversion mechanism 80, and a box rear portion 90 from the front to the rear (strictly back and forth).

(Rear part of the box)
The box rear portion 90 includes a rear frame 93 having a rear box connecting beam 92 for connecting the pair of rear box side portions 91a and 91b and the rear box side portions 91a and 91b, and a rear box side portion 91a. , 91b, a rear cover 94 that opens and closes the rear surface, and a frame-like or lattice-like rear brush support 95 installed across the rear box side portions 91a, 91b.
The rear cover 94 is detachably and pivotally installed near the lower edges of the rear box side portions 91a and 91b by a hinge mechanism, and the rear brush support 95 is disposed in the front-rear direction near the upper edges of the rear box side portions 91a and 91b. The hinge mechanism is provided with a gap in the front and rear, and is movable in the front-rear direction, detachable and rotatable.

That is, the rear brush support 95 is installed movably in the front-rear direction, detachably and pivotably by a hinge mechanism having a gap in the front-rear direction near the upper edges of the rear box side portions 91a, 91b. Are installed in the vicinity of the lower edge of the rear box side portions 91a and 91b so as to be detachable and rotatable by a hinge mechanism.
Therefore, the rear brush support 95 opens in an inverted V shape with respect to the rear box side portions 91a and 91b, and the rear cover 94 opens in a V shape with respect to the rear box side portions 91a and 91b. The three parties have a substantially N shape and eventually become substantially planar.
That is, the dust stored in the box front portion 10 can be easily discharged (same as collecting) by opening the front cover 14 and the front brush support 15.

When the rear cover 94 and the rear brush support 95 are closed, a gap between the upper edge portion of the rear cover 94 and the upper edge portion of the rear brush support 95 and the lower edge portion of the rear cover 94 and the lower edge of the rear brush support 95 are provided. The rear filter 70 forms a through hole (movable in the vertical direction).
Further, protrusions 96a and 96b are formed in the vicinity of the lower edges of the rear box side portions 91a and 91b, and these are engaged with through holes 16a and 16b formed in the box front portion 10 so as to be detachable and rotatable. It constitutes a part of the hinge mechanism to be stopped. Further, rear shaft rotation support portions 97a and 97b are provided at substantially the center of the rear box side portions 91a and 91b, and this rotatably supports the rear shaft 81 constituting the rear rotation translation conversion mechanism 80.

(Post filter)
The rear filter 70 is a rectangular plate member having a ventilation portion 71 formed with a gap (not shown) through which air can pass and dust in the air can be captured, and has flexibility. Further, rear translation portions (specifically, “rack”, hereinafter referred to as “rear rack”) 72 a and 72 b constituting the rear rotation translation conversion mechanism 80 are provided on the rear surfaces of the rear filter 70 at both edges in the width direction. (Same on the leeward side).
Therefore, normally, dust is trapped on the front surface of the rear filter 70 (same as the windward surface), so that the dust scraped off from the rear filter 70 is prevented from adhering to the racks 72a and 72b.

(Post-rotation translation conversion mechanism)
The rotation transmission portion of the rear rotation translation conversion mechanism 80 includes a rear shaft 81, rear pinions 82a and 82b fixed to the rear shaft 81, and meshed with the rear racks 72a and 72b (formed on the rear filter 70), respectively. It is fixed to the front box side 11b (right side in the figure) of the shaft 81 and is selectively driven to rotate by the two-option rotary drive unit.
That is, the rear rotation translation conversion mechanism 80 includes a rack / pinion mechanism including a rear rack 72a and a rear pinion 82a, and a rack / pinion mechanism including a rear rack 72b and a rear pinion 82b. Therefore, the filter 70 is reliably translated by rotating the front driven gear 83b. At this time, since the filter 70 receives a force at both edges, the filter is not twisted (for example, deformed into a parallelogram).

(Rear brush)
When the rear filter 70 is translated, the rear brush 60 slides on the ventilation portion 71 of the rear filter 70 and scrapes off dust.
That is, the rear upper brushes 61 and 62 are installed on the upper edge portion of the rear cover 94 and the upper edge portion of the rear brush support 95, respectively. The lower edge portion of the rear cover 94 and the lower edge portion of the rear brush support 95 are respectively provided. Rear lower brushes 63 and 64 are installed. Then, the rear upper brushes 61 and 62 and the rear lower brushes 63 and 64 are respectively installed in the same form as the front upper brushes 41 and 42 of the front brush 40 and the front lower brushes 43 and 44 (such as fiber collapse). Therefore, when the rear filter 70 translates, the dust captured by the rear filter 70 is stored in the dust box 319 and is not dissipated outside the dust box 319.

  A plurality of urging means (compression springs, elastic resins, air-filled flexible tubes, etc., hereinafter collectively referred to as “coil springs”) 50 are provided between the front brush support 15 and the rear brush support 95. Has been placed. Therefore, by adjusting the pressing strength of the coil spring 50, the front brush 40 and the rear brush 60 can respectively hold the front filter 20 and the rear filter 70 with a desired pressing pressure. Further, even when one or both of the front brush 40 and the rear brush 60 are worn, the pressing pressure does not fluctuate greatly and no gap is generated between the front filter 20 and the rear filter 70.

(Interaction between components)
5 and 6 are perspective views illustrating a part of the relationship between the constituent members of the two-sheet cleaning unit in the filter device according to the first embodiment of the present invention. FIG. 5 illustrates the front brush support from the front. FIG. 6 is a perspective view in which the rear filter is directly viewed from the rear.

  In FIG. 5, the front shaft 31 constituting the front rotation translation conversion mechanism 30 (which constitutes the front rotation transmission unit) and the rear shaft 81 constituting the rear rotation translation conversion mechanism 80 (which constitutes the rear rotation transmission unit) The front driven gear 33b (which constitutes the front rotation transmission portion) and the rear driven gear 83b (which constitutes the rear rotation transmission portion) are close to each other (right side in FIG. 5). Is located).

  Between the front shaft 31 and the rear shaft 81, the front brush support 15 is disposed at a position close to the front shaft 31, and the rear brush support 95 is disposed at a position close to the rear shaft 81. At this time, since both the front brush support 15 and the rear brush support 95 have a lattice shape, dust enters the gap between the lattices, and the dust passes through the gap.

Further, the front box connecting beam 12 is formed with a front shaft cover 19 formed of a concave portion having an arcuate cross section opened to the rear side, and the front shaft support 18 formed of a concave portion having an arcuate cross section opened to the front side is formed on the front brush support 15. (Not shown in FIG. 4) is formed, and the front shaft 31 is disposed in the cylindrical shape formed by the front shaft covers 18 and 19, so that dust is prevented from adhering to the front shaft 31. Dust is easily discharged from the dust box 319.
Similarly, the rear cover 94 is formed with a rear shaft cover 99 formed of a concave portion having an arcuate cross section opened to the front side, and the rear brush support 95 is formed with a rear shaft cover 98 having an arcuate cross section opened to the rear side ( 3), the rear shaft 81 is arranged in a cylindrical shape formed by the rear shaft covers 98 and 99, so that dust is prevented from adhering to the rear shaft 81, and dust can be easily discharged from the dust box 319. become.

  Further, a coil spring 50 (shown by a dotted line in FIG. 5) is disposed between the front brush support 15 and the rear brush support 95, and the distance between the two is increased. That is, as described above, since the front brush support 15 and the rear brush support 95 are installed on the front frame 13 and the rear frame 93 so as to be movable in the front-rear direction, the spreading strength of the coil spring 50 is selected. Thus, the pressure at which the front brush 40 grips the front filter 20 and the pressure at which the rear brush 60 grips the rear filter 70 are adjusted simultaneously. In addition, the arrangement | positioning point of the coil spring 50 is not limited to what is shown in figure, A position and a number are selected suitably.

FIG. 6 shows a state in which the pair of rear pinions 82a and 82b fixed to the rear shaft 81 of the rear rotation translation conversion mechanism 80 are engaged with the rear racks 72a and 72b of the rear filter 70, respectively. That is, such a rack / pinion mechanism reliably translates the rear filter 70.
In the present invention, the front rotation translation conversion mechanism 30 and the rear rotation translation conversion mechanism 80 are each provided with a rack / pinion mechanism, but the present invention is not limited to this and has the same function. For example, a mechanism including a plane formed on the filter and a rotating roller that holds the plane may be provided.

(Dust discharge)
As described above, through holes 16a and 16b are formed in the vicinity of the lower edge of the front box side portions 11a and 11b of the box front portion 10, and in the vicinity of the lower edge of the rear box side portions 91a and 91b of the box rear portion 90. Since the projections 96a and 96b are formed, the box front portion 10 and the box rear portion 90 are opened in a V shape with this as a fulcrum. Therefore, by opening both, the dust stored between the filter 20 and the filter 70 can be easily discharged (collected).
Further, the dust stored in the box front portion 10 can be easily discharged (same as collecting) by opening the front cover 14 and the front brush support 15. Similarly, dust stored in the box rear portion 90 can be easily discharged (same as collection) by opening the rear cover 94 and the rear brush support 95.

As described above, the filter device 1000 includes two filters, and these are separately translated by one two-option rotation driving means (one actuator is installed, which will be described in detail later). Therefore, the number of filter driving devices can be minimized.
Furthermore, since two filters are arranged on the front and rear, the amount of movement of the filter during cleaning can be suppressed. Therefore, in the apparatus equipped with the filter device 1000 in the machine, the filter is kept accommodated in the machine, that is, externally. The filter can be cleaned in a state where it cannot be visually recognized.
Furthermore, since the constituent members constituting the filter device 1000 are detachable and rotatable with respect to each other, the stored dust can be easily discharged (collected).

[Embodiment 2]
(Filter device: Two-sheet type tandem arrangement)
7 to 9 show a filter device according to Embodiment 2 of the present invention, FIG. 7 is a perspective view seen from the front, FIG. 8 is a partially enlarged perspective view, and FIG. 9 is a part of components. It is a perspective view which shows (four-option rotation drive unit).

(overall structure)
7 and 8, the filter device 2000 includes a four-choice rotation drive unit 400, a first two-sheet cleaning unit 300a that is selectively driven by the four-option rotation drive unit 400, and a second two-sheet cleaning unit 300b. have.

(Two-sheet cleaning unit)
The first two-sheet cleaning unit 300a is the same as the two-sheet cleaning unit 300 shown in the first embodiment. That is, in the front cleaning block 100, the front driven gear 33b protrudes from the front box side portion 11b (right side in the drawing), and the rear driven gear 83b protrudes from the rear box side portion 91b (right side in the drawing).
On the other hand, the second two-sheet cleaning unit 300b differs from the two-sheet cleaning unit 300 shown in the first embodiment in the arrangement of the front driven gear and the rear driven gear.
That is, in the first two-sheet cleaning unit 300a (same as the front cleaning block 100), the end portion of the front shaft 31 protrudes from the front box side portion 11b (right side in the drawing), and the front driven gear 33b is fixed to the protruding portion. However, in the second two-sheet cleaning unit 300b, instead of this, the end of the front shaft 31 protrudes from the front box side portion 11a (left side in the figure), and the front driven gear 33a is provided in the protruding portion. It is fixed. Similarly, the rear driven gear 83a protrudes from the rear box side portion 91a.
For this reason, the four driven gears (the front driven gear 33b, the rear driven gear 83b, the front driven gear 33a, and the rear driven gear 83b) are arranged close to each other. For this reason, the four-choice rotation drive unit 400 that selectively rotates the four driven gears is small.

(Four-option rotary drive unit)
In FIG. 9, the four-option rotary drive unit 400 includes a first front drive gear 411, a first rear drive gear 412, a first driven gear 41b, a rear driven gear 83b, a front driven gear 33a, and a rear driven gear 83b. 2 front drive gear 413 and second rear drive gear 414 (hereinafter may be collectively referred to as “drive gear 410”).

For cleaning each filter, for example, first, the first front drive gear 411 is rotated to clean the front filter 20a of the first two-sheet cleaning unit 300a. At this time, the position of the upper filter or the lower edge of the front filter 20 is detected by a position sensor (not shown) that defines the movement range of the front filter 20a, and the first front drive gear is reciprocated within the range. 411 is rotated forward and reverse. The outer round trip may be performed once or twice or more.
Next, for example, the first rear drive gear 412 is rotated to clean the rear filter 70 of the first two-sheet cleaning unit 300. Similarly, the front filter 20 and the rear filter 70 of the second two-sheet cleaning unit 300b are cleaned.
The order of cleaning the filters is not limited, and may be before or after cleaning. For example, a filter in which the differential pressure before and after the filter is measured and the measured differential pressure is a predetermined value or more is measured. You may make it implement cleaning only to.

The structure of the four-option rotary drive unit 400 is not limited, but the drive gear 410 is selectively rotated by a single actuator (for example, an electric motor, hereinafter referred to as “drive motor”). It is said.
For example, a first rotation gear (installed on the first shaft) rotated by one drive motor (freely forward and reverse), a second shaft installed parallel to the first shaft, A second rotating gear that is axially movable on the second shaft and that is always meshed with the first rotating gear, and an actuator that moves the second rotating gear in the axial direction (hereinafter referred to as a “selected motor”). And the second rotating gear may selectively mesh with any of the drive gears 410 by moving.
When one drive motor rotates in only one direction and does not reverse, an intermediate gear is arranged between the drive motor and the first rotation gear, and the first rotation gear is adjusted by operating the intermediate gear. You may make it roll or reverse.

(Control of cleaning work)
Furthermore, the control means for controlling the cleaning work is not limited. For example, the “all cleaning start signal” output when the value obtained by integrating the operating time of the air conditioner equipped with the filter device 2000 reaches a predetermined threshold, or the differential pressure before and after the specific filter is predetermined. Any device may be used as long as it receives the “partial cleaning start signal” that is output when the threshold value is reached and starts the drive motor and the selection motor. Alternatively, a complete cleaning start signal or a partial cleaning start signal may be manually input.
Further, the range in which the filter translates may be defined by the number of rotations of the rotating portion of the drive motor 410 or the like instead of the position sensor described above.

  As described above, the filter device 2000 includes four filters, and these are separately translated by one four-choice rotation drive unit 400 (one actuator is installed, which will be described in detail later). Therefore, the number of filter driving devices can be minimized. In addition, since two filters are arranged at the front and rear, the amount of movement of the filter during cleaning can be suppressed. Therefore, in an apparatus equipped with the filter device 2000 in the machine, the filter is kept in the machine, that is, externally. The filter can be cleaned in a state where it cannot be visually recognized.
