  In addition, a horizontally elongated air outlet 4 is provided at the middle position in the front-rear direction of the bottom wall 1C of the casing 1, and the air outlet 4 is provided with a horizontal flap 44 and a vertical flap 45.

  Further, a cleaning brush 17 having a dust box 20 described later is mounted in a storage portion 30 provided at a position closer to the front side than the outlet 4 of the casing 1 and close to the lower end of the front wall 1A. ing. As shown in FIG. 2, the cleaning brush 17 is configured by attaching brushes 19 at four positions in the circumferential direction of the outer peripheral surface of the brush shaft 18 so as to extend in the axial direction of the brush shaft 18. Is done.

  And as shown in FIG. 2, the heat exchanger 7 and the fan 8 are accommodated in the ventilation path from the said suction inlet 3 in the said casing 1 to the said blower outlet 4, and the air-conditioning mechanism X is comprised by these. . The heat exchanger 7 is connected to the first heat exchanger 7A extending in the vertical direction so as to be opposed to the suction port 3 and the upper end of the first heat exchanger 7A, and from here to the rear wall 1E side. It has a substantially chevron-shaped bent shape composed of the second heat exchanger 7B that is inclined downward.

  On the other hand, the front space between the front suction port 3A of the casing 1 and the front surface of the first heat exchanger 7A, the upper portions of the first heat exchanger 7A and the second heat exchanger 7B, and the upper surface suction. In the space on the upper surface side between the mouth 3B, a cleaning mechanism Y described below is disposed across these spaces.

  As shown in FIGS. 2 to 4, the cleaning mechanism Y is configured by connecting and integrating a pair of left and right casing bodies 14 </ b> A and 14 </ b> B formed in the opposite direction in the width direction. In the converted state, the casing 1 has a side view shape curved from the front suction port 3A of the casing 1 along the inner surface of the upper suction port 3B. That is, the casing bodies 14A and 14B are both a pair of left and right side wall portions 15 and 16 having a curved side view shape, and a frame in which the side wall portions 15 and 16 are connected by a lattice material and integrated. The cleaning unit casing 14 is configured by connecting the side wall portions 16 of the first casing body 14 </ b> A and the side wall portions 16 of the second casing body 14 </ b> B in a state of abutting with each other.

  Further, guide grooves 15a and 16a are provided in portions of the inner edges of the side walls 15 and 16 of the casing bodies 14A and 14B corresponding to the upper surface suction port 3B of the casing 1, respectively. On the other hand, among the casing bodies 14A and 14B, each of the front portions corresponding to the front suction port 3A of the casing 1 is covered with the frame-shaped filter holder 43 so as to cover it from the outside (front side). However, it is attached so that it can rotate in the front-rear direction with the upper edge side as the center of rotation.

  A plate formed by stretching a mesh-like filter material 13b on the inner side of the grid-like frame 13a on the front side of each of the casing bodies 14A and 14B of the cleaning unit casing 14 so as to cover them. A mesh-like filter 13 is disposed. In this case, on the upper surface side of each casing body 14A, 14B, the filter 13 is inserted into the guide groove 15a of the one side wall portion 15 and the guide groove 16a of the other side wall portion 16 on the left and right edges. It is guided by the guide grooves 15a and 16a and is movable along the bending direction of the casing bodies 14A and 14B. Further, the filter 13 is prevented from being lifted by the filter press 43 at the front surface portions of the casing bodies 14A and 14B.

  As shown in FIGS. 2 and 5, the filter 13 has a first pulley 11 and a second pulley whose front ends 13 c are spaced apart in parallel in the vertical direction at the front portions of the casing bodies 14 </ b> A and 14 </ b> B. The belt 10 is wound around the belt 12 and is moved integrally with the belt 10 as the belt 10 travels.

  That is, as shown in FIG. 2, the filter 13 is arranged such that its rear end 13 d is located at the rear end of the cleaning unit casing 14 and its front end 13 c is located in the vicinity of the first pulley 11. Basic. This arrangement state is a position during normal air conditioning operation, and is hereinafter referred to as “first filter position”.

  On the other hand, during the cleaning operation for cleaning the filter 13, the first pulley 11 rotates forward and the belt 10 travels in the direction of arrow a, and the filter 13 is moved together with the belt 10 to the “first filter position”. Is pulled out from the first pulley 11 to the upper surface side of the second pulley 12. The position of the filter 13 at this time is referred to as a “second filter position”. Further, in the “second filter position”, the first pulley 11 rotates in the reverse direction and the belt 10 travels in the direction of the arrow b, so that the filter 13 together with the belt 10 moves from the “second filter position” to the “first filter position”. The filter position is returned.

  As described above, when the filter 13 reciprocates between the “first filter position” and the “second filter position”, dust collected on the surface of the filter 13 by the cleaning brush 17 is scraped off. Thus, the dust collecting function of the filter 13 is regenerated.

  The prior invention is as described above. Although the dust collected on the surface of the filter 13 is scraped off by the cleaning brush 17, in the case of the air conditioner of the prior invention, the air sucked from the suction port 3 passes through the filter 13. In some cases, a part of the dust in the air may adhere to the back surface of the filter 13 through the mesh of the filter 13. In such a case, when the dust is scraped off with the cleaning brush 17 only from the front surface side of the filter 13 as in the air conditioner of the prior invention, it adheres to the back surface side of the filter 13. In addition, almost no dust is scraped off, and there is also a phenomenon that a part of the dust adhering to the front surface side of the filter 13 is pushed into the back surface side of the filter 13 by the cleaning brush 17. The present invention has been made paying attention to this point, and has been made to improve the problem of dust adhesion on the back side of the filter in the air conditioner as in the above-described embodiment of the prior invention.

  In the present invention, the following configuration is employed as a specific means for solving the above-described problems.

In 1st invention of this application, the cleaning mechanism Y which cleans the surface of the air-conditioning mechanism X which has arrange | positioned the heat exchanger 7 and the fan 8 in the casing 1, and the filter 13 arrange | positioned in the windward side of the said heat exchanger 7 An air conditioner comprising: a back surface cleaner mechanism H that discharges dust adhering to the filter 13 from the back surface side to the front surface side of the filter 13 on the back surface side of the filter 13. Yes.

In the second invention of the present application, in the air conditioner according to the first invention, the cleaning brush 17 is used as the cleaning mechanism Y, and the back-side cleaner mechanism H is provided to face the cleaning brush 17. It is characterized by having.

In the third invention of the present application, in the air conditioner according to the first or second invention, as the back surface side cleaner mechanism H, dust attached to the filter 13 on the back surface side of the filter 13 is removed from the back surface of the filter 13. A large number of protrusions 51 for discharging from the side toward the surface side are provided.

According to a fourth invention of the present application, in the air conditioner according to any one of the first to third inventions, the filter 13 is folded and driven along a back surface side cleaner mechanism H.

In the fifth invention of the present application, in the air conditioner according to any one of the first to fourth inventions, a dust box 20 is provided below the cleaning mechanism Y and the back surface side cleaner mechanism H. .

In the sixth invention of the present application, in the air conditioner according to the first invention, the cleaning mechanism Y is hung between the toothed first pulley 11 and the second pulley 12, and the pulleys 11, Toothed to reciprocate between the first pulley 11 and the second pulley 12 in a state where the filter 13 that is driven by rotation of 12 and is locked on the surface side is wound around the first pulley 11 side. A belt 10 is provided, and on the radially outer side of each of the pulleys 11 and 12, there is provided a regulating means P that restricts the belt 10 from floating from the outer peripheral side of the pulleys 11 and 12. Yes.

In the seventh invention of the present application, in the air conditioner according to the sixth invention, as the back surface side cleaner mechanism H, a roller 33 that rotates by winding the filter 13 coaxially with the first pulley 11 is provided. And a plurality of protrusions 51 for discharging dust adhering to the filter 13 through the mesh of the filter 13 from the back side to the front side of the filter 13 on the outer peripheral surface of the roller 33. Yes.

The eighth invention of the present application is characterized in that, in the air conditioner according to the seventh invention, the moving speed of the filter 13 and the rotational peripheral speed of the roller 33 are made equal.

  In the present invention, the following effects can be obtained.

(A) According to the air conditioner according to each of the first to fifth inventions of the present application, the cleaning mechanism Y cleans the dust adhering to the front surface side of the filter 13, and the back surface side of the filter 13. Since the dust adhering to the filter 13 can be discharged toward the front surface side, the dust does not remain attached to the back surface side of the filter 13. As a result, the filter 13 has the effect of being cleaned as highly as possible on both the front and back surfaces.

(B) According to the air conditioner pertaining to the sixth aspect of the present invention, in addition to the effects of the air conditioner pertaining to the first aspect of the present invention, there are the following effects. That is, the cleaning mechanism Y is hung between the toothed first pulley 11 and the second pulley 12, driven by the rotation of the pulleys 11 and 12, and the filter locked on the surface side. 13 is provided with a toothed belt 10 that reciprocates between the first pulley 11 and the second pulley 12 in a state of being wound around the first pulley 11 side, and the radial directions of the pulleys 11 and 12 Since the belt 10 is provided with a regulating means P for regulating the lifting of the belt 10 from the outer peripheral sides of the pulleys 11 and 12, the belt 10 is slackened due to, for example, elongation due to change over time or looseness. Even if it occurs, the slack portion is restricted by the restricting means P from floating from the outer peripheral side of the pulleys 11 and 12, and the belt 10 in the pulleys 11 and 12 Generation of jump is and reliably prevented.

  As a result, for example, in the case of a configuration in which belts are arranged on both the left and right sides of the filter and the filters are moved in synchronization with each other, there is no deviation in the left and right movement timing of the filter, so that the filter is twisted. Without cleaning, the cleaning action of the filter is accurately performed.

  In addition, since the belt does not lift up, the filter attached to the belt does not lift up, and therefore the filter 13 does not interfere with the nearby members and is not damaged. As a result, the operational reliability of the air conditioner is improved.

  Further, the tooth skipping of the belt 10 is prevented by the regulating means P that regulates the lifting of the belt 10, so that, for example, the structure is simple as compared with the case where a conventional tension applying means is provided. In addition, the cost is low, and the cost reduction of the cleaning mechanism Y is promoted.

(C) According to the air conditioner pertaining to the seventh aspect of the present invention, in the air conditioner pertaining to the sixth aspect of the present invention, the filter 13 is coaxial with the first pulley 11 as the back side cleaner mechanism H. A plurality of rollers 33 that rotate around the filter 13 and discharge dust attached to the filter 13 on the outer peripheral surface of the roller 33 from the back side to the front side of the filter 13 through the mesh of the filter 13. Since the protrusion 51 is provided, the first pulley 11 can be used as a drive source for the back surface side cleaner mechanism H, and the configuration of the back surface side cleaner mechanism H is simplified.

(D) According to the air conditioner pertaining to the eighth invention of the present application, in the air conditioner pertaining to the seventh invention, the moving speed of the filter 13 and the rotational peripheral speed of the roller 33 are made equal. Therefore, there is no relative speed difference between the filter 13 and the outer peripheral surface of the roller 33, so that a large number of protrusions 51 provided on the outer peripheral surface of the roller 33 are attached to the back surface of the filter through the mesh of the filter 13. The dust can be discharged (extruded) as it is from the back side of the filter 13 to the front side. As a result, it is possible to prevent dust from falling and accumulating on the back side of the filter 13 as much as possible.

  Hereinafter, the present invention will be specifically described based on preferred embodiments.

  1 and 2 show an air conditioner Z that is an embodiment of the invention of the prior application and an embodiment of the invention of the present application.

  The description of the air conditioner according to the embodiment of the invention of the prior application with reference to FIGS. 1 to 5 applies to the air conditioner according to the embodiment of the invention of the present application as it is. The description for the air conditioner according to the embodiment will be used for the description of the embodiment of the present invention to the extent that no contradiction arises, and will be described below based on the above description. I will explain the parts that are not. First, components unique to the embodiment of the present invention, which were not in the air conditioner of the invention of the prior application, will be described. The air conditioner according to the embodiment of the present invention is illustrated in FIGS. 6 to 7. Thus, a back surface side cleaner mechanism H that discharges dust adhering to the back surface of the filter 13 from the back surface side to the front surface side of the filter 13 is provided on the back surface side of the filter 13. In this case, in the embodiment shown in FIGS. 6 to 7, for example, a synthetic resin roller 33 that rotates by winding the filter 13 coaxially with the first pulley 11 is used as the back surface side cleaner mechanism H. And a large number of protrusions (for example, synthetic resin brushes) for discharging dust adhering to the filter 13 over the entire outer peripheral surface of the roller 33 from the back side to the front side of the filter 13 through the mesh of the filter 13. 51, and in that case, the moving speed of the filter 13 and the rotational peripheral speed of the roller 33 are equalized, and the protrusions 51 provided on the entire outer peripheral surface of the roller 33 are passed through the mesh of the filter 13. The dust is pushed out from the back surface side of the filter 13 toward the front surface side.

  Next, the drive mechanism of the filter 13 in the illustrated embodiment will be described in detail. As shown in FIG. 5, the drive mechanism includes a belt unit U in which a toothed belt 10 is wound between a toothed first pulley 11 and a second pulley 12 that are spaced apart in the vertical direction. 11 and 12 are arranged to face each other with a predetermined interval (specifically, approximately the width dimension of the casing bodies 14A and 14B) in the axial direction, and the first pulley 11 of one belt unit U and the first pulley unit 11 of the other belt unit U. The first pulley 11 is connected by a roller 33 and integrated, and the second pulley 12 of one belt unit U and the second pulley 12 of the other belt unit U are connected by a connecting shaft 38. It is configured by integrating. The first pulley 11 of one belt unit U is selectively rotated by the filter drive motor 31 in the forward rotation method and the reverse rotation direction, so that the belts 10 provided in the belt units U and U are respectively provided. , 10 run synchronously.

  In this case, a locking hole 47 having a long axis in the belt length direction is formed in the belt 10 at a predetermined pitch. Further, locking projections 48 are provided on the lower surfaces of the left and right sides of the frame member 13a of the filter 13 at the same pitch as the locking holes 47 on the belt 10 side. By engaging the protrusion 48 in the locking hole 47 on the belt 10 side, the filter 13 is integrated with the belt 10, and the “first filter position” and the above as the belt 10 reciprocates. It is reciprocated between “second filter positions”.

  In this embodiment, of the first pulley 11 and the second pulley 12, only the first pulley 11 is driven, and the second pulley 12 is driven by the first pulley 11 via the belt 10. However, in other embodiments, the second pulley 12 is individually driven by the filter drive motor 30 independently of the first pulley 11 side, as shown by the chain line in FIG. It can also be configured as follows.

  Here, the engagement protrusion 47 on the filter 13 side is engaged with the engagement hole 47 of the belt 10 that is wound around the first pulley 11 and the second pulley 12, so that the engagement between both of them is engaged. In order to ensure the reliability of the locking action, the locking protrusion 48 is not locked to the locking hole 47 within the range of the thickness dimension of the belt 10, but the locking protrusion 48 is fixed to the belt. 10 is protruded from the back surface side (that is, the tooth forming side), and even if the filter 13 is slightly lifted from the front surface side of the belt 10, it is still necessary to ensure the locking action. However, when the locking protrusion 48 protrudes to the lower surface side of the belt 10 through the locking hole 47, the locking protrusion 48 is formed with teeth provided on the belt hooking surfaces of the first pulley 11 and the second pulley 12. Because of the interference, the locking projection 48 cannot be protruded to the lower surface side of the belt 10.

  For this reason, in this embodiment, the first pulley 11 and the second pulley 12 have an axially two-part structure composed of the first pulley bodies 11A and 12A and the second pulley bodies 11B and 12B, respectively. By forming small-diameter relief portions 11a, 12a that are not provided with teeth, and by causing the locking projections 48 to enter the relief portions 11a, 12a, the locking projections 48 protrude toward the back side of the belt 10. If possible.

  By the way, in the case of adopting a configuration in which the filter 13 is engaged with the belt 10 wound between the first pulley 11 and the second pulley 12 and moved, as described above, It is necessary to keep the moving action properly at all times, and in order to ensure the proper moving action, it is possible to reliably prevent the occurrence of tooth skipping between the pulleys 11 and 12 and the belt 10. Necessary. In order to prevent such a tooth skipping phenomenon, in this embodiment, as described below, the right and left belt units U and U are respectively restricted by the side wall portions 15 and 16 of the cleaning unit casing 14. P is provided. Hereinafter, several structures of the regulating means P will be described.

  Since the structure on the side wall 15 side of the regulating means P and the structure on the side wall 16 side are substantially the same, here, the structure on the side wall 15 is taken as an example, and referring to FIGS. Will be described in detail. FIG. 8 is a cross-sectional view of the belt unit U portion, and FIG. 9 is a side view of the portion.

First Structure Example of Restricting Means P As shown in FIG. 8, the first pulley 11 and the second pulley 12 of the belt unit U are both inside the side wall portion 15 of the cleaning unit casing 14 (cleaning unit casing 14 The inner side in the width direction). And in this structural example, as shown in FIGS. 8-10, the width direction outer side part of the said belt 10 hung around the said 1st pulley 1 and the said 2nd pulley 12 in the peripheral part of the said side wall part 15. As shown in FIG. Is extended from the outer side in the thickness direction of the belt 10 (that is, the outer side in the radial direction of the pulleys 11 and 12) with a predetermined interval “s”, and the wall body 40 is formed to extend. The restriction means P is used.

  Here, as shown in FIG. 10, the interval “s” is set to be smaller than the meshing height dimension “h” of the teeth of the first pulley 11 and the second pulley 12 and the teeth of the belt 10. The

  In this structural example, the wall body 40 is continuously provided over the entire circumference of the belt 10 as shown in FIG. 9, but in the other structural examples, the wall body 40 is partially provided. You may provide in the objective (for example, the part corresponding to the said 1st pulley 11 and the 2nd pulley 12).

  Thus, by providing the wall body 40 so as to cover the outer side of the belt 10, the belt 10 is inevitably stretched due to a change with time, or only the first pulley 11 is driven. Even if slack is generated due to the generated slack, the slack portion is restricted by the inner surface of the wall body 40 when it floats from the outer peripheral side of the pulleys 11 and 12. As a result, the occurrence of the tooth jump phenomenon of the belt 10 in the pulleys 11 and 12 is prevented in advance and reliably, and the rotational phase between the pair of belt units U and U is always properly maintained. Therefore, the filter 13 whose both sides in the width direction are locked by the pair of belt units U and U is smoothly reciprocated by the belts 10 and 10 without causing twisting and the like. The cleaning action of the filter 13 by the cleaning brush 17 is accurately performed.

  Further, since the belt 10 is not lifted up, the filter 13 attached to the belt 10 is not lifted up. Therefore, the filter 13 is not damaged by interference with its neighboring members. The durability of the air conditioner is improved and the operational reliability of the air conditioner is improved. In this case, in this structural example, from the viewpoint of more surely preventing the filter 13 from being lifted, the filter guide 41 is extended to the tip side of the filter guide 41, and the filter guide 41 directly lifts the filter 13. It can be regulated.

  In this structure example, as shown in FIG. 9, the filter guide 41 is provided in a scattered manner in the belt meshing range of the first pulley 11. In addition, on the second pulley 12 side, a movable filter presser 46 that can be rotated around the pin 46 a is provided, and a curved plate-like presser part 46 b formed on the movable filter presser 46 is provided with the second pulley 12. The lifting of the filter 13 is restricted by pressing it against the filter 13 wound on the side by its own weight. Further, the guide portion 46c provided in the movable filter presser 46 is configured such that the end portion of the filter 13 is moved to the second filter position when the filter 13 moves back from the “second filter position” to the “first filter position” side. The pulley 12 is prevented from being caught in the pulley 12 and reliably returns the filter 13 to the “first filter position”.

  By the way, instead of driving only the first pulley 11 of the first pulley 11 and the second pulley 12, only the first pulley 11 and the second pulley 12 can be driven to rotate. As described above, when such a double drive method is adopted, the belt 10 is not loosened and tensioned due to the pulley drive, and thus the prevention of the lifting of the belt 10 is essentially taken into consideration. Although it can be said that it is not necessary, in reality, it is considered that the belt 10 is lifted due to the elongation of the belt 10 due to a change with the passage of time, resulting in tooth skipping. Therefore, even when the both-side drive method is adopted as described above, the restricting means P functions effectively to prevent tooth skipping.

Second Structural Example FIG. 11 shows a second structural example of the regulating means P. In this structural example, the wall body 40 provided on the side wall portion 15 of the cleaning unit casing 14 is used as the restricting means P, and is extended at the tip of the wall body 40 so as to cover the side edge of the filter 13. The portions are integrally formed, and this extended portion functions as the filter guide 41.

  Accordingly, in this structure example, for example, the structure is simplified and compared with the case where the wall body 40 and the filter guide 41 are provided separately from the wall body 40 functioning as the regulating means P. Cost reduction will be promoted.

Third Structural Example FIG. 12 shows a third structural example of the regulating means P. In this structural example, a wall 40 is extended on the side wall 15 of the cleaning unit casing 14 so as to cover the filter 13 attached to the outer surface side of the belt 10 from the outside, and the wall 40 is regulated. It is made to function as both P and the filter guide 41. Therefore, in this structural example, the tooth skipping of the belt 10 with respect to the first pulley 11 and the second pulley 12 is always performed through the anti-lifting action of the filter 13.

Fourth Structural Example FIG. 13 shows a fourth structural example of the regulating means P. In this structural example, a roller 42 is attached to the side wall 15 of the cleaning unit casing 14, and the roller 42 functions as the restricting means P. In this case, the roller 42 includes a large-diameter first roll portion 42 a corresponding to the side edge of the belt 10 and a small-diameter second roll portion 42 b corresponding to the filter 13 attached to the belt 10. It is a stepped roll. An appropriate number of rollers 42 are provided at predetermined intervals in at least the belt meshing range of the first pulley 11 and the second pulley 12.

  In this structural example, when the belt 10 or the filter 13 is in contact with the first roll part 42a or the second roll part 42b of the roller 42 and its lifting is restricted, the roller 42 rotates, For example, as compared with the case where the belt 10 is brought into contact with a wall surface or the like, the driving resistance of the belt 10 is reduced, and further, the cost reduction due to the small capacity of the filter driving motor 31 is promoted. .

  In the above embodiment, a wall-mounted air conditioner (indoor unit) has been described as an example. However, the present invention is not limited to this, and for example, an air conditioner of a ceiling-embedded type, a floor-mounted type, or the like. Needless to say, this can also be applied.
