JP 2007-147122 A

  However, in the air conditioner described in Patent Document 1, although the guide piece is opened outside the casing, the inner guide and the outer guide constituting the guide piece are integrally formed. Is substantially the same as the width of the movement path of the filter. Therefore, the opening is not wide enough to insert the filter, and it takes time to insert the filter.

  In view of the above problems, an object of the present invention is to provide an air conditioner in which a filter can be easily inserted into an opening.

In order to achieve the above object, an air conditioner according to the present invention includes a filter disposed along an inner surface side of a suction port of a casing, a cleaning means for cleaning the filter, and the filter with respect to the cleaning means. A moving path for moving, and a guide part that constitutes a part of the moving path, and turning the other end about the one end side of the guide part, thereby moving the moving path to the outside of the casing. An air conditioner that opens,
The guide portion includes a front surface member disposed on the front surface side of the filter and a back surface member disposed on the back surface side of the filter.

  According to the said structure, the guide part is provided in the front-surface member and the back surface member separately, respectively, can rotate a front surface member and a back surface member, respectively, and can open a moving path | route toward the casing outer side. . Also, when the filter is inserted, if the filter hits the surface member, the surface member rotates in the opening direction and the opening becomes larger, so that the filter can be easily inserted.

  In the air conditioner of the present invention, in the state where the movement path is opened, the width between the front surface member and the back surface member is increased from one end side to the other end side of the guide portion. Is preferred.

  That is, when the movement path is closed, the width of the movement path is set to be approximately the same as a whole, and the front surface member and the back surface member are arranged to face each other with a space therebetween. Therefore, by rotating the front member and the back member in the direction in which the movement path opens, the width of the guide part (the width of the front member and the back member) serving as the opening part of the movement path is set to the guide part. It is possible to widen from one end side to the other end side.

  In other words, the inner surface of the guide portion (opening portion) can be formed in a tapered shape so as to become narrower from the entrance / exit side toward the back, and the filter can be easily inserted into the movement path.

  Moreover, in the air conditioner of this invention, it is preferable to set it as the structure which rotates a back surface member via a link mechanism by rotating a surface member. With such a configuration, by rotating the front surface member, the back surface member can also be rotated, and the operability is improved.

  In the air conditioner of the present invention, it is preferable that the link mechanism has a configuration in which the back member rotates with the rotation of the surface member after the surface member rotates to a predetermined angle.

  According to the above configuration, the back surface member does not rotate until the front surface member rotates by a predetermined angle. Therefore, it is possible to increase the width of the front surface member and the back surface member from one end side to the other end side of the guide portion only by rotating the front surface member.

  Furthermore, by rotating both the front surface member and the back surface member in this state, the guide portion can be directed outward from the casing, and the filter can be smoothly introduced into the movement path.

  Moreover, what is necessary is just to rotate a surface member to a reverse direction, when making a guide part function as a movement path | route. Thereby, the width | variety of a surface member and a back surface member can be narrowed, and both can be returned to the original parallel state (state in which the space | interval of a surface member and a back surface member becomes substantially constant).

  In the air conditioner of this invention, it is preferable that the holding | maintenance mechanism which fixes and hold | maintains the surface member rotated by the predetermined angle with the back surface member in the state is provided. With such a configuration, when the filter is inserted, the width of the guide portion, which is the opening of the movement path, can be maintained at a sufficient width, so that the filter can be easily inserted.

  In the air conditioner of the present invention, in the state where the front surface member is fixed and held by the holding mechanism, the back surface member is held by the link mechanism in a state inclined at a certain angle with respect to the front surface member. It may be.

  With such a configuration, the angle formed by the front surface member and the back surface member can be maintained at a predetermined angle only by the holding mechanism that holds only the front surface member, and the back surface member is held by the link mechanism. A holding mechanism for holding the back member is not required.

  In the air conditioner of the present invention, the holding mechanism may restrict the rotation of the surface member. With such a configuration, it is possible to prevent the surface member from rotating too much. Further, it is not necessary to provide a separate rotation restricting member. In addition, you may make it the surface member and back surface member which comprise the said guide part turn freely around the same rotation axis.

  In the air conditioner according to the present invention, a part of a moving path for moving the filter is configured by a guide portion including a front surface member and a back surface member, and the other end is opened and rotated around one end side of the guide portion. Thus, since the movement path is opened toward the outside of the casing, the filter can be easily inserted into the movement path.

It is a front view.

  The air conditioner includes an indoor unit 1 and an outdoor unit (not shown). The indoor unit 1 includes a casing 4 in which a heat exchanger 2, an indoor fan 3, and the like are installed. As shown in FIGS. 1 to 6, the casing 4 has a front panel 5 whose front opening is supported so as to be openable and closable, and a suction port formed in a lattice shape on the top surface side of the casing 4 to suck indoor air. 6 and a blower outlet 7 formed in the lower part of the front surface of the casing 4 for blowing out the hot and cold air subjected to heat exchange.

  The entire surface of the air outlet 7 is covered with the air guide panel 8. The air guide panel 8 is sized to cover the air outlet 7 and the upper part of the air outlet 7. A rotation shaft is formed at the upper end and lower end of the wind guide panel 8, and the other end side is rotated around one rotation shaft, whereby the wind blows out in a desired direction.

  The front opening of the casing 4 is an opening for mounting the sheet-like filter 9 into the casing 4. The upper part of the front panel 5 is rotatably fixed to the side surface of the casing 4, and the front surface of the casing 4 can be opened by pulling the lower part upward.

  As shown in FIG. 2, a ventilation path is formed in the casing 4 between the suction port 6 and the blowout port 7, and the filter 9 and the indoor heat exchanger are provided in this ventilation path with the suction port 6 side as an upstream side. 2. The blower fan 3 is arranged in this order. The indoor heat exchanger 2 is formed in an inverted V shape. And in the casing 4, the cleaning means 12 which cleans the filter 9 is provided.

  The suction port 6 is formed on substantially the entire left and right direction of the top surface of the casing 4. The filter 9 is disposed along the inner surface of the suction port 6. Specifically, the filter 9 is flexible and includes a right filter 9 b that covers the right half of the suction port 6 and a left filter 9 a that covers the left half of the suction port 6. All of the air sucked from the suction port 6 passes through the filter 9, thereby removing dust and dust in the air.

  The filters 9a and 9b are supported by the guide means 10, respectively. The guide means 10 is provided on each of the inner surface side of the side wall 17 of the casing 4 and both side surfaces of the central body 18 that bridges the approximate center of the casing 4 in the front-rear direction, whereby the left and right end portions of the left and right filters 9a and 9b are Each structure is supported.

  The guide means 10 not only supports the filter 9 in the vicinity of the inner surface of the suction port 6 but also functions as a movement path A for moving the filter 9. That is, the guide means 10 is provided along the suction port 6 of the casing 4 (region 10a), and extends further forward from there. Specifically, as shown in FIGS. 2 and 3, the guide means 10 is inclined downward on the front side of the region 10 a to reach the vicinity of the front panel 5 (region 10 b), and from there to the U-shape inside (Region 10c) and passes between the region 10b and the heat exchanger 2 to reach the vicinity of the suction port 6 (region 10d). And each area | region 10a-10d is connected by the smooth curve.

  Thus, the guide means 10 functions as a movement path A in which the filter 9 can move. The movement path A is provided so as to pass through the cleaning means 12 in the region 10b, and the filter 9 moving along the movement path A is cleaned here. As shown in FIG. 6, the guide means 10 and the cleaning means 12 can be assembled together and are handled as one unit. Therefore, the guide means 10 and the cleaning means 12 are assembled in the casing 4 as a unit. FIG. 6 shows a state in which the left guide portion 50 of the left and right guide portions 50 is closed, and the right guide portion 50 is opened.

  The guide means 10 includes an inner rail 21 that guides the inner peripheral side of the moving path A formed in a U-shape, and an outer rail 22 that guides the outer peripheral side of the moving path A. If the left and right ends of the filter 9 are sandwiched between the inner rail 21 and the outer rail 22 of the guide means 10 formed in this way, the movement of the filter 9 can be guided to be substantially U-shaped. .

  The length of the moving path A preferably has a length that reaches the position where the upper end of the filter 9 is introduced into the cleaning means 12 when the filter 9 is moved downward. By doing in this way, it can clean to the upper end part of the filter 9. FIG.

  In the region 10c, a portion from the vicinity of the boundary between the region 10b and the region 10c to a position closest to the front panel 5 is a guide portion for opening and closing the movement path A instead of the inner rail 21 and the outer rail 22. 50 is provided. The guide portion 50 is provided on the front side of the casing (closer to the front panel 5) than the cleaning means 12.

  The guide portions 50 are provided on the left filter 9a side and the right filter 9b side, respectively. The guide unit 50 constitutes a part of the moving route A when the moving route A is closed, and functions as an opening of the moving route A when the moving route A is opened.

  The guide unit 50 includes a front surface member 52 and a back surface member 53. The front surface member 52 and the back surface member 53 have a plate shape that is long in the left-right direction of the filter 9 (the left-right longitudinal direction of the air conditioner). When the movement path A is closed, the front surface member 53 functions as the outer rail 22 and the back surface member 52 functions as the inner rail 21. Therefore, the front surface member 52 and the back surface member 53 have a curved surface in accordance with the curved shape of the region 10c.

  Of the end portions along the longitudinal direction, the surface member 52 is provided with a bearing 52a having a C-shaped cross section at the rear end portion (the upper end portion when the air conditioner is viewed from the front). A guide shaft 54 whose axial direction is parallel to the left and right longitudinal direction of the air conditioner is provided on the front side of the cleaning means 12. The bearing 52 a is attached to the guide shaft 54 and is rotatable about the guide shaft 54. In other words, the lower end (other end) of the surface member 52 is rotatable about the upper end side (one end side).

  The guide shaft 54 is fixed to the cleaning means 12. The cleaning means 12 is fixed to the guide means 10 at both ends in the left-right length direction, whereby the positional relationship between the guide shaft 54 and the guide means 10 is fixed.

  Similarly, the back member 53 is also provided with a bearing 53a having a C-shaped cross section at the rear end portion (upper end portion when the air conditioner is viewed from the front) of the end portions along the longitudinal direction. It is possible to rotate around 54. That is, the lower end (the other end) of the front surface member 52 and the back surface member 53 is rotatable about the same rotation axis on the upper end side (one end side).

  When the front surface member 52 and the back surface member 53 are caused to function as a part of the movement path A without being rotated (in the closed posture), the front surface member 52 and the back surface member 53 are opposed to each other with a space therebetween. A gap for guiding the filter 9 is provided between them. This gap is set to be approximately the same as the width X of the movement path A other than the guide portion 50 so that the filter 9 guided along the inner rail 21 and the outer rail 22 can continuously pass smoothly. Is done.

  The guide portion 50 can open the movement path A by rotating (opening rotation) so that the other end side (lower end side) of the front surface member 52 and the back surface member 53 faces the front of the casing. At this time, since the guide portion 50 and the region 10b are arranged on a substantially straight line, the filter 9 can be easily introduced into the moving path A or led out from the moving path A with the guide portion 50 as an entrance / exit. It becomes possible.

  Actually, to open and rotate the guide portion 50, the back surface member 53 is rotated together with the front surface member 52 via the link mechanism 55 by performing a rotation operation so as to pull up the lower end portion of the front surface member 52.

  The link mechanism 55 will be described. Engagement pins 56 are provided at both left and right ends of the surface member 52 so as to be substantially parallel to the longitudinal direction of the surface member 52. In addition, receiving plates 57 extending from the back surface member 53 in a substantially vertical direction are provided at both left and right ends of the back surface member 53. The receiving plate 57 is provided with a long hole-shaped engagement hole 58 into which the engagement pin 56 of the surface member is loosely fitted. The engagement hole 58 has a structure having play with respect to the direction in which the engagement pin 56 rotates when the surface member 52 is opened and rotated in a state where the engagement pin 56 is loosely fitted. The engagement pin 56 and the engagement hole 58 constitute a link mechanism 55.

  The engaging pin 56 and the receiving plate 57 are provided on the side close to the guide shaft 54, but may be provided on the side far from the guide shaft 54. Note that if the engagement pin 56 and the receiving plate 57 are provided on the side closer to the guide shaft 54, a predetermined angle is obtained compared to the case where the engagement pin 56 and the receiving plate 57 are provided on the side far from the guide shaft 54. The height of play necessary to obtain θ1 can be reduced. Therefore, it is difficult to get in the way inside the air conditioner.

  The operation of the guide unit 50 having the above configuration will be described. Now, it is assumed that the guide unit 50 is in a closed posture. When removing the filter 9 from the indoor unit in order to clean the filter 9 or replace the filter 9, the front panel 5 is first opened. Then, the surface member 52 is exposed. The front surface member 52 is provided with a lock mechanism 59 that locks the front surface member 52 and the back surface member 53 in a closed posture.

  As shown in FIG. 6, the lock mechanism 59 in the present embodiment is a mechanism that can be locked / released by sliding the operating rod in the left-right direction. If it can be adopted. By releasing the lock mechanism 59, the surface member 52 can be rotated.

  As shown in FIG. 8, when the surface member 52 that can be turned is turned open (turned clockwise in the drawing), the engaging pin 56 is also turned. The engagement pin 56 contacts the engagement hole 58 at an intermediate position M where the angle formed by the front surface member 52 and the rear surface member 53 for rotating the front surface member is a predetermined angle θ1.

  The back surface member 53 tries to rotate (closed) in the closing direction due to gravity. However, if the surface member 52 continues to open and rotate while the engagement pin 56 is in contact with the engagement hole 58, the back surface member 53 also opens and rotates accordingly.

  That is, as shown in FIG. 10, when the front surface member 52 is further rotated from the intermediate position M, the back surface member 53 is in a state where the engagement pin 56 and the engagement hole 58 are in contact with each other, in other words, in a state where the predetermined angle θ1 is maintained. Are simultaneously opened and rotated. When the surface member 52 is further rotated from the intermediate position M by a predetermined angle θ 2, the open posture is set.

  In the present embodiment, when the front surface member 52 rotates simultaneously with the back surface member 53, the front surface member 52 and the back surface member 53 rotate around the same axis (guide shaft 54), so that the relative positions of each other. Since the relationship does not change, the link mechanism can have a simple structure.

  As described above, in the open posture of the guide portion 50, the width between the front surface member 52 and the back surface member 53 is approximately the width X at the upper end side (one end side) and the width X1 (the other end side) at the lower end side (the other end side). X1> X), and widens from the upper end side toward the lower end side. That is, the inner surface of the guide portion 50 can be tapered so as to become narrower from the doorway 50a side toward the back, and the filter 9 can be easily inserted into the movement path A.

  In the present embodiment, a holding mechanism 60 that fixes and holds the surface member 52 in an open posture is provided. The holding mechanism 60 includes a holding bar 61 that is formed so as to interfere with the rotation trajectory of the surface member 52. The holding bar 61 has a base fixed to the cleaning means 12, and a tip 61a is formed in a semispherical shape, and is bent so as to be substantially perpendicular to the main body 61b. That is, the tip portion 61 a is formed so that the axial direction thereof is substantially parallel to the longitudinal direction of the surface member 52.

  On the other hand, an opening 62 is formed in the surface member 52 at a position where the holding bar 61 abuts. The opening 62 can be passed through the main body 61b of the holding bar 61, but is formed so that the tip 61a contacts the opening edge. Further, the holding bar 61 is formed so as to be inclined with respect to the surface member 52 in the open posture, and the tip end portion 61a is formed so as to contact the edge of the opening 62 immediately before the surface member 52 reaches the open posture. .

  The operation of the holding mechanism 60 having the holding bar 61 and the opening 62 will be described. When the guide portion 50 is turned open and the surface member 52 approaches the open posture, the leading end portion 61a of the holding bar 61 comes into contact with the edge of the opening 62 formed in the surface member 52, as shown in FIG. Since the holding bar 61 is made of synthetic resin and has elasticity, when the external force is applied to the tip, it is easily elastically deformed and bent.

  Therefore, if the rotation of the surface member 52 is continued in a state where the tip 61a is in contact with the opening edge, the tip 61a bends backward while riding on the edge of the opening 62, and even when it passes over the opening 62. The guide section 50 is held by the holding bar 61 in this posture (FIG. 12).

  Thereby, the front-end | tip part 61a of the holding | maintenance bar 61 will be in the state caught in the opening 62 of the surface member 52, and even if a hand is released from the surface member 52, the surface member 52 hold | maintains an open posture. At this time, the back surface member 53 tries to rotate in the closing direction by gravity, but cannot close and rotate because the engagement pin 56 is in contact with the engagement hole 58. In other words, the back surface member 53 is held by the link mechanism 55.

  Then, by holding the front surface member 52 by the holding mechanism 60, the angle formed by the front surface member 52 and the back surface member 53 can be maintained at a predetermined angle θ1. In this holding state, the filter 9 is taken out from the movement path A.

  When the surface member 52 in the open posture is to be further opened and rotated, the end edge closest to the bearing 52 a among the end edges of the opening 62 comes into contact with the holding bar 61. The rotation is restricted. That is, the holding mechanism 60 also serves as a stopper that restricts the rotation of the surface member 52.

  The filter 9 has such a length that the tip thereof is substantially at the same position as the lower end of the guide portion 50 in a state of use of the air conditioner (a state in which the filter 9 is disposed so as to cover the suction port 6). In the open posture of the guide portion 50, as shown in FIGS. 3 and 5, when the back surface member 53 is rotated together with the front surface member 52, the filter 9 is also rotated by being pushed by the back surface member. Therefore, when the guide portion 50 is in the open posture, the tip of the filter 9 has a shape facing the front of the casing 4 and can be easily taken out.

  Thus, the back surface member 52 can move the tip of the filter 9 (the tip on the front panel side) from the back of the air conditioner to a place where it can be easily taken out. Thereby, it becomes easy to take out the filter 9 with the tip of the filter 9.

  In a state where the front surface member 52 is held by the holding mechanism 60, the distance between the front surface member 52 and the back surface member 53 is a funnel shape (side view) that is large on the entrance / exit 50a side and decreases toward the back side. The distance on the back side is substantially the same width X as the movement path A other than the guide portion 50, and the entrance / exit 50a side is larger than the back side.

  Therefore, the filter 9 can be easily inserted into the movement path A from the entrance / exit 50a having a width larger than the width of the movement path A. The indoor unit of a separate type air conditioner as in this embodiment is often mounted at a high place on the wall surface. Therefore, it is often difficult to take out and insert the filter 9.

  Since the filter 9 is thin and flexible, it is easy to bend. Therefore, if the filter 9 is inserted from the entrance / exit 50a with the lower part of the filter 9, the filter 9 is likely to bend. Therefore, if the opening width of the entrance / exit is substantially the same as the movement path A as in the conventional example, the insertion is performed. Difficult to do.

  However, by making the opening width of the entrance / exit larger than the width X of the movement path A as in the present invention, it becomes easy to put the filter 9 into the opening even if the filter 9 is slightly bent. Since the opening width gradually narrows from the opening tip to the back, the filter is inserted along the back to reach the moving path.

In this way, the filter 9 can be easily inserted and removed.
In addition, in order to return the guide part 50 to the state of a movement path | route, the holding | maintenance bar 61 will bend and will remove | deviate from the opening 62 by pushing the surface member 52 in the closing rotation direction. Then, keep pressing and return to the moving path state. And what is necessary is just to lock by a locking mechanism.

  In the present embodiment, the link mechanism 55 includes the engagement pin 56 and the engagement hole 58. Instead of providing the engagement hole 58, the link plate 55 is provided with a protrusion, and the protrusion The link mechanism may be configured by contacting the portion and the engagement pin 56. In this case, if the lower surface of the protrusion is at a position where the engagement hole 58 and the engagement pin 56 are in contact with each other, the front surface member and the back surface member can be in contact with each other at a predetermined angle θ1.

  Alternatively, the link mechanism may be configured such that a protrusion is provided only on the receiving plate 57 and the protrusion is in contact with the surface side of the surface member 52 with the front surface member and the back surface member at a predetermined angle θ1. Good.

  In the present embodiment, only the holding mechanism 60 that holds the front surface member is described, but a holding mechanism that holds the back surface member may be provided at the same time. In the present embodiment, the holding mechanism 60 that holds the surface member is present. However, the holding mechanism 60 that holds the surface member may be omitted. In this case, the front member is not held, but a holding mechanism for holding the back member is provided instead.

  When the guide is in the open state, the front surface member tries to rotate in the closing direction due to gravity, so the distance between the front surface member and the back surface member of the guide portion 50 is the same as the movement path state. At this time, when the filter is inserted into the filter, when the filter hits the surface member, the surface member can be rotated in the opening direction, so that the filter rotates in the opening direction, so that the width between the surface member and the back surface member is large. Become. Therefore, even with such a configuration, the filter can be easily inserted.

  In the present embodiment, the front surface member and the back surface member constituting the guide portion are rotatable around the same rotation shaft 54 provided on the outer rail 22 side. It is good. For example, the front surface member rotates about a rotation shaft provided on the outer rail 22 side, and the back surface member rotates about a rotation shaft provided on the inner rail 21 side.

  As shown in FIGS. 13 and 15, the filter 9 includes a filter network 13 and a filter frame 14 that supports four sides of the filter network 13. The filter frame 14 includes a vertical frame 14a that supports the side and a horizontal frame 14b that supports the upper side and the lower side.

  As shown in FIG. 14, the vertical frame 14a is formed in a wave shape when viewed from the side. By forming it in a wave shape, irregularities are formed in the vertical direction (moving direction) on the inner surface side of the vertical frame 14a. On the other hand, in the region 10 c, a gear 32 that is rotated by the motor 30 is provided inside the back surface member 53, and the left and right end portions of the back surface member 53 are partially cut away, and the gear 32 enters the movement path A from there. It is exposed (see FIG. 6).

  The unevenness engages with the gear 32. The filter 9 can be moved back and forth by the rotation of the gear 32. Moreover, since the filter 9 is easily bent in the vertical direction by making the unevenness into a wave shape, the filter 9 is easily folded back into a U shape.

  The shape of the concavo-convex surface formed on the inner surface side of the vertical frame 14a is not limited as long as it can be meshed with the teeth of the driven gear 32, but the pitch of the concavo-convex and the tooth pitch of the driven gear 32 should be the same. preferable. Tooth skipping can be more effectively prevented.

  Further, ribs 15 are provided so as to divide the inside of the filter frame 14 into a lattice shape. The rib 15 is fixed to the filter net 13 and supports the filter net 13. It is possible to prevent the filter 9 from warping or wavy. The rib 15 includes a vertical rib 15a arranged in the vertical direction and a horizontal rib 15b arranged in the horizontal direction. The vertical ribs 15a are formed thin, and the horizontal ribs 15b are formed thicker than the vertical ribs 15a. With this configuration, the filter 9 can be easily bent in the vertical direction while maintaining the rigidity in the horizontal direction.

  Moreover, as shown in FIG. 14, the slit 16 is provided between the horizontal rib 15b and the vertical frame 14a of the filter frame 14, and both are made discontinuous. By making the vertical frame 14a and the horizontal rib 15b discontinuous, the vertical frame 14a is hardly affected by the horizontal rib 15b, so that the flexibility of the filter 9 in the vertical direction can be maintained. The material of the filter frame 14 may be any material as long as it is flexible, and any of synthetic resin such as polypropylene (PP), polyethylene terephthalate (PET), and soft resin, rubber, and paper may be used.

  A filter mesh 13 that allows air sucked from the suction port 6 to pass through is stretched at the top of the filter 9, but a thin resin sheet 13 a is stretched at the bottom of the filter 9 instead of the filter mesh 13. The lower part of the filter is structured so that air does not pass therethrough. The resin sheet 13a is formed to be thin like the longitudinal ribs 15a, thereby ensuring the longitudinal flexibility of the entire filter 9. The filter net 13 may be stretched over the entire surface of the filter 9.

  The cleaning means 12 is provided in the area 10 b of the guide means 10. Since the region 10 b is formed in a straight line, the filter 9 can be easily attached to the cleaning means 12. Furthermore, since the cleaning means 12 is provided on the front side of the casing 4, it is easy to attach the filter 9 to the cleaning means 12.

  The cleaning means 12 is composed of an upper case 37 and a lower case 38 having a substantially U-shaped cross section, and the front of the casing 4 is bridged in the horizontal direction with the concave portions of the upper case 37 and the lower case 38 facing each other. In this way, it is fixed to the casing 4.

  There is a gap between the upper case 37 and the lower case 38, and the filter 9 can travel through this gap. A very narrow space is maintained between the upper case 37 and the lower case 38 and the surface of the filter 9. Both left and right ends of the suction part 34 are opened. That is, the filter 9 can pass through the cleaning means 12 formed in a box shape as a whole.

  One end of the lengthwise ends of the cleaning means 12 is open, and the suction device 35 is connected to the other end. The suction device 35 includes a suction fan and is connected to a duct (not shown) communicating with the outside. A suction force is generated by rotating the suction fan, and the dust on the filter 9 can be sucked by the cleaning means 12. The sucked air is exhausted from the duct to the outside.

  Further, the interval between the upper case 37 and the lower case 38 is set to be substantially the same as the interval between the horizontal ribs 15 b of the filter 9. When the side walls of the upper case 37 and the lower case 38 overlap with the lateral ribs 15b, the interior of the cleaning means 12 becomes a substantially sealed space, so that the suction force is increased.

  According to the above configuration, when the filter 9 is cleaned, the filter 9 is moved forward by the rotation of the gear 32. At this time, since the movement path A is formed by the guide means 10 so as to be folded in a U shape in front of the casing 4, the front end of the filter 9 is guided to the rear side (downstream side) while curving with the forward movement. The entire surface of the filter 9 can be cleaned.
