  However, in the air conditioner described in Patent Document 1, dust attached to the filter is scraped off with a brush, which may cause damage to the filter and may cause dust attached to the brush to reattach to the filter. There is a problem that dust must be discarded every time dust accumulates in the dust box.

  On the other hand, the filter device described in Patent Document 2 is a method of removing dust attached to the filter with a brush instead of removing it with air suction force, so that the filter is damaged or dust is collected in the cleaning device. There is no fear. However, in this filter device, the suction port formed in the suction nozzle is brought into contact with the filter surface to suck in dust, so if the area of the suction port is increased to widen the dust suction range, the suction force becomes weaker and dust removal In order to prevent a decrease in efficiency, a suction exhaust device with a large air volume is required. Conversely, if the suction area is increased by reducing the area of the suction port, it takes time to clean the entire filter. It was.

  Therefore, in the present invention, a filter cleaning device capable of removing dust from a wide range of filters at a time without using a suction exhaust device having a large air volume while adopting a method of removing dust by a fluid such as air, and the cleaning device It aims at providing the air conditioner which mounts.

Filter cleaning device according to the present invention, inside are arranged such half-like dust removing box between the flow path of air is formed is opposed to the opening surface, the gap between the two boxes, the filter A moving means is provided that is set at a passing interval and moves the filter relatively in a direction perpendicular to the longitudinal direction of the box, and the filter has a plurality of protruding shapes that divide the surface into a plurality of sections. The horizontal ribs are arranged at equal intervals in the longitudinal direction of the filter, and the interval between the horizontal ribs is substantially the same as the width of the box, or is formed at intervals that equally divide the width of the box. The two boxes are opposed to each other with a gap through which the lateral ribs can pass, and the box is moved between the open end faces of the two boxes by operating the moving means. And forming a cylindrical box body with transverse ribs interposed therebetween, and removing the dust attached to the filter by circulating air to said box body.

  According to the above configuration, the filter is accommodated in the space surrounded by the two boxes, and air is circulated in this limited space to remove the dust adhering to the filter. There is no need to inhale air from the inlet. Therefore, a device with a large air volume is not required as a means for circulating air, and there is no possibility that the apparatus becomes large.

  Furthermore, the flow velocity of air can be easily increased, and dust attached to the filter can be efficiently blown off by this air flow and removed. Here, the half-shaped dust removal box only needs to be formed so that its opening surfaces can be abutted with each other, and does not need to be formed in a symmetrical shape.

  As a means for circulating air in the box, for example, a fan, an intake port for taking air into the fan, and a discharge port for releasing air from the fan can be used. By connecting the intake port and the discharge port to the box, air can be circulated in the box.

  Further, as other air circulation means, it is possible to use an air sending means for sending air or an air suction means for sucking air. In this case, air can be circulated between the vent and the air sending means or the air suction means by forming the vent in the box. However, it is preferable to use an air suction means from the viewpoint that there is no risk of dust scattering around the gap between the boxes.

  The air flowing through the flow path can be increased in flow rate as the cross-sectional area of the flow path is reduced. That is, even if the area of the half-divided opening surface as the dust removal box is the same, the longer the surface is, the larger the flow velocity of the air flowing in the flow path can be. In other words, if the cross-sectional area of the flow path is small, the influence on the flow velocity of the air flowing in the flow path is small even if the length of the flow path is increased.

  Therefore, if the dust removing box has a small cross-sectional area of the flow path, an air flow having a high flow rate can be easily generated even if the dust removing box is formed so as to cross the filter. Specifically, if an air inlet is formed on one end of the box in the cross-filter direction and a suction means for sucking air is connected to the other end, it is possible to generate an air flow with a high flow velocity in the entire flow path. Thus, dust attached to the filter in the flow path can be efficiently removed.

  The filter cleaning device may be provided with a moving means for moving the filter in a direction orthogonal to the longitudinal direction of the box by setting the gap between the boxes to an interval through which the filter can pass. The entire filter can be automatically cleaned. The moving means may move the filter with respect to the fixed dust removal box, or may move the dust removal box with respect to the fixed filter.

  As the gap between the boxes becomes larger than the thickness of the filter, the moving means can operate more smoothly. On the other hand, air flows into the box from the gap, and the flow velocity of the air flowing through the flow path decreases. Will do. Conversely, if the gap between the two boxes is reduced, when the moving means is operated, the opening end face of the box comes into contact with dust on the filter surface, and dust attached to the filter is scattered around.

  Therefore, in the present invention, the filter includes a plurality of protruding horizontal ribs that divide the surface into a plurality of sections, and the horizontal ribs are arranged at equal intervals in the filter vertical direction, and the interval between the horizontal ribs is a box. The two boxes are placed opposite to each other with a gap through which the horizontal ribs can pass, and the moving means is operated to place the horizontal ribs between the open end faces of both boxes. Thus, a cylindrical box body was formed by both boxes and the lateral ribs interposed between them, and dust attached to the filter was removed for each compartment accommodated in the box body.

  According to the above configuration, the two boxes are arranged to face each other with a gap through which the lateral rib can pass, that is, the boxes are arranged in a state of being separated from the filter surface. There is no risk of the box coming into contact with the filter surface and scattering dust.

  Further, by positioning the lateral rib between the opening end faces of both boxes, it is possible to close the gap between the boxes with the lateral rib. Thus, a cylindrical box body can be formed by both boxes and the lateral rib interposed between them, and by operating the suction means in this state, the flow velocity of the air flowing through the flow path is not reduced. The section surrounded by the lateral ribs can be efficiently cleaned.

  When cleaning of one section is completed, if the suction means is stopped and the filter is moved by the distance between the lateral ribs, the adjacent section can be accommodated in the box body. The filter can be cleaned for each section. That is, it is possible to clean the filter without scattering dust only by operating the moving means intermittently.

  As another configuration for preventing the dust on the filter surface from scattering, when cleaning the filter portion in the flow path, the moving means is stopped and both boxes are brought into contact with the filter to form the flow path. After the cleaning of the filter part is completed, the moving means is operated with at least the dust removal box arranged on the filter surface side where the dust adheres separated from the filter, and the uncleaned filter part in the flow path You can also put in.

  Specifically, for example, a dust removal box arranged on the filter surface side is provided so that the distance to the filter can be changed, and is supported so as to be always separated from the filter by the biasing force of a spring. When cleaning the filter, the box may be brought into contact with the filter against the biasing force of the spring by a solenoid or the like.

  The filter cleaning device described above is mounted on an air conditioner that includes a suction port and an air outlet, and a filter that is interposed between the filter and removes dust in the air, without increasing the size of the air conditioner. It becomes possible to add a filter cleaning function. The air conditioner is not particularly limited as long as it includes a filter that removes dust in the air, and examples thereof include an air conditioner, a humidifier, a dehumidifier, an air purifier, and a heater. .

  In addition, when a filter cleaning device equipped with a moving means for reciprocating the filter in the vertical direction is mounted on the air conditioning device, the conventional filter can be used to prevent warping and waves and maintain shape retention. Since a certain degree of rigidity was required, when the filter was moved, the moved filter had to be exposed to the outside of the air conditioner, resulting in a problem that the appearance was impaired.

  Therefore, in the present invention, a plurality of protruding lateral ribs that divide the filter surface into a plurality of sections are provided, and the lateral ribs are arranged at equal intervals in the longitudinal direction of the filter. Formed to be almost the same as the width, both boxes are placed facing each other with a gap through which the lateral ribs can pass, and the moving means is operated so that the lateral ribs are positioned between the open end faces of both boxes. A cylindrical box body is formed by the ribs interposed between them and a cleaning device configured to remove dust adhering to the filter for each compartment accommodated in the box body is mounted on the air conditioner, and the filter is mounted. The filter holding means is formed so as to be bendable in the vertical direction, and the filter moved in the vertical direction is bent and held in a substantially U shape when the moving means is operated.

  According to the above configuration, even if the strength of the filter in the vertical direction is lowered and the filter can be bent in the vertical direction, sufficient shape retention can be maintained by the plurality of horizontal ribs formed in the filter. The filter moved in the direction can be bent and accommodated in the air conditioner, and the appearance is not impaired.

  As described above, according to the present invention, the halved dust removal boxes in which air flow paths are formed are arranged so that their opening surfaces face each other, and the air filter is installed in the gap between the boxes. Since the dust is adhered to the filter by arranging and circulating air in the box, the speed of the air circulating in the flow path can be adjusted without using a large air volume as a means for circulating the air. Thus, the dust attached to the filter can be efficiently blown away and removed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a description will be given of a case where a separate type air conditioner indoor unit having a cooling / heating function as a main function is used as an air conditioner, and the filter cleaning device according to the present invention is mounted on the indoor unit. FIG. 1 is an external perspective view of an indoor unit of an air conditioner, and FIG. 2 is a cross-sectional view thereof.

  In FIG.1 and FIG.2, the suction inlet 2 and the blower outlet 3 are each formed in the upper part and the lower part of the indoor unit main body 1 of an air conditioner, and the blower outlet 3 from the suction inlet 2 is formed in the inside of the main body 1. FIG. A ventilation path is formed between the filter 4, the filter 4, the indoor heat exchanger 5, and the blower fan 6 in this order, with the suction port 2 side as the upstream side. The indoor unit is provided with a filter cleaning device for cleaning the filter 4.

  A louver 9 for changing the direction of the air flow in the vertical direction is swingably attached to the air outlet 3. The louver 9 operates quickly when the air-conditioning air flow is turned off, and closes the air outlet 3 as shown. That is, the louver 9 also has a role of an opening / closing panel for the air outlet 3.

  When the air conditioning operation is performed in the indoor unit configured as described above, first, the blower fan 6 is operated to suck indoor air from the suction port 2, and the indoor air passes through the filter 4 and comes into contact with the indoor heat exchanger 5. . The indoor air conditioned by being warmed or cooled by the indoor heat exchanger 5 is discharged into the room through the outlet 3.

  The front portion of the indoor unit body 1 is formed to be openable and closable by a front panel 7. A filter guide 8 is formed inside the front panel 7. As shown in FIG. 3, when the front panel 7 is lifted upward and opened, the tip of the filter guide 8 rotates in conjunction with this. Oriented forward, this makes it possible to insert the filter 4. When the front panel 7 is closed, the front end of the filter guide 8 is also interlocked and rotated downward, and the filter 4 is set in the indoor unit body 1 as shown in FIG.

  The suction ports 2 are formed at two positions on the left and right of the upper surface of the main body 1, and below (in the vicinity of the downstream side), as shown in FIG. 4, the suction ports 2 are formed in a vertically long rectangle corresponding to each suction port 2. Two filters 4 are arranged side by side. The length of the filter 4 in the horizontal direction is substantially the same as that of each suction port 2. The vertical length of the filter 4 is longer than the vertical length of the suction port 2, and the lower portion of the filter 4 is bent and held along the filter guide 8 with the front panel 7 closed.

  Next, the filter cleaning device will be described. The filter cleaning device includes a dust removal box (referred to as a front side box) 10 covering the surface of the filter 4, a dust removal box (referred to as a back side box) 11 covering the back surface of the filter 4, a suction fan 12 as a suction means, and a filter 4. Moving means for reciprocating in the vertical direction. The front-side box 10 and the back-side box 11 are formed in a halved shape, and as shown in FIG. 5, they can be abutted against each other at the opening surfaces 10b and 11b.

  As shown in FIG. 4, the front side box 10 and the back side box 11 are slightly forward of the suction port 2, that is, the filter 4 portion near the boundary between the front panel 7 and the top panel 13 where the suction port 2 is formed. It is arranged so as to face each other, so that the air sucked from the suction port 2 is not prevented from passing through the filter 4.

  The front side box 10 and the back side box 11 are formed in an elongated shape, and are installed with the longitudinal direction oriented in the horizontal direction of the filter so as to cross the two filters 4 arranged side by side on both sides. The opening end faces 10a and 11a are arranged with an interval x so as to face each other.

  Specifically, as shown in FIG. 5, a vent 15 is formed at one end in the longitudinal direction of the front side box 10 and the back side box 11, and the other end side is maintained with a gap x between them. Is held fitted. The other end side of the pipe 14 is connected to the suction fan 12.

  That is, the boxes 10 and 11 are arranged to face each other, thereby forming a box body 16 in which a vent hole 15 is formed on one end side and the suction fan 12 is connected on the other end side. The space surrounded by this is the flow path 17. The flow path 17 has a vent 15 of the box body 16 as an inlet, and is configured to generate an air flow by sucking air from the inlet to the suction fan 12.

  In the present invention, dust is attached to the filter 4 by generating an air flow in the flow path 17 and flowing air in a direction substantially parallel to the filter 4 from the side of the filter 4 accommodated in the box body 16. It has become. Two slit-shaped gaps 18 (interval x) are formed in the box body 16 in the longitudinal direction, and the filter 4 can move in the longitudinal direction in the gap 18.

  In the present embodiment, the box body 16 is formed such that the front side box 10 and the back side box 11 are formed as separate bodies and are arranged to face each other, but two slits are provided in the longitudinal direction of the cylindrical body. Thus, the front side box and the back side box can be integrally formed.

  The specific configuration of the filter 4 will be described. As shown in FIGS. 6 and 7, the filter 4 includes a mesh filter 19 and a synthetic resin frame 31 provided around the mesh filter 19 in order to reinforce the mesh filter 19. The frame 31 is composed of a vertical frame 32 and a horizontal frame 33. Further, the filter 4 is reinforced with vertical ribs 20 and horizontal ribs 21.

  A plurality of the vertical ribs 20 and the horizontal ribs 21 are made of synthetic resin and formed on the surface of the mesh filter 19 at equal intervals. The horizontal frame 33 and the horizontal rib 21 are formed in a protruding shape to prevent the filter 4 from warping or wavy, that is, thick, whereas the vertical frame 32 and the vertical rib 20 are formed in the horizontal frame 33. And it is formed thinner than the lateral rib 21. Thereby, the filter 4 can be easily bent in the vertical direction while maintaining the rigidity in the horizontal direction.

  A rack portion 22 is provided in the vertical direction on the outer edge portion of the vertical frame 2. The rack portion 22 meshes with a pinion 28 which is a moving means described later, and reciprocates the filter 4 in the vertical direction. The rack portion 22 has a shape obtained by forming a strip-like material into a corrugated shape, and this peak portion functions as a rack. It is like that. Further, as shown in FIG. 8, the rack portion 22 is formed separately from the adjacent lateral ribs 21. In this way, the rack portion 22 is formed in a corrugated shape and separated from the adjacent lateral ribs 21 to maintain the longitudinal flexibility of the filter 4.

  As described above, the mesh filter 19 that allows the air sucked from the suction port 2 to pass therethrough is stretched on the upper part of the filter 4, and a thin resin sheet 23 is used instead of the mesh filter 19 at the lower part of the filter 4. The lower part of the filter is designed to prevent air from passing through. In addition, the resin-made sheet | seat 23 is formed in the thin wall similarly to the vertical rib 20, and, thereby, the bending property of the vertical direction is ensured over the filter 4 whole.

  The moving means for reciprocating the filter 4 in the vertical direction includes a filter holding means 24 for holding the filter 4 and a driving means 26 for moving the filter 4 by the motor 25, as shown in FIGS. . The filter holding means 24 is composed of a pair of guide paths. The guide path is formed in a substantially U-shaped cross section, and the right and left ends of the filter 4 can be inserted. By passing the rigid horizontal frame 33 and the lateral rib 21 between the pair of left and right guide paths, the filter 4 is held in the guide path without being deformed.

  The cross-sectional shapes of the filter holding means 24 are represented as black portions and shaded portions in FIG. As shown in FIG. 2, the filter holding means 24 is provided along the suction port 2, and is gently inclined downwardly on the front side of the suction port 2, and between the front side box 10 and the back side box 11. A U-shaped path 24a is formed that passes through and descends substantially vertically along the front panel 7, and then U-turns inward and rises toward the suction port. The filter guide 8 described above constitutes a part of the filter holding means with the front panel 7 closed.

  The drive means 26 includes a motor 25, a drive gear 27 connected to the motor 25, a pinion 28 and a rubber roller 29 that mesh with the drive gear 27. A gear having the same shape as a pinion (not shown) is attached to the rotation shaft of the rubber roller 29, so that the pinion 28 and the rubber roller 29 rotate in the same direction.

  The pinion 28 is disposed so as to be partially exposed from the filter holding means 24 near the box body 16 and mesh with the back surface side of the rack portion 22 provided in the filter 4. The rubber roller 29 is disposed so as to be partly exposed in the U-shaped path 24a, and rotates in contact with the back side of the filter 4 in the U-shaped path 24a, whereby the bent filter 4 is moved by the frictional force thereof. It is configured to perform smoothly.

  One set of driving means 26 is attached to each of the left and right guide paths of the filter holding means. However, as shown in FIG. 9, one motor 25 is provided for two sets of driving means 26 and is arranged on the left and right. Each of the drive gears 27 is fixed to the same rotating shaft 30 connected to the motor 25 and is driven to rotate in the same way on the left and right.

  When the filter 4 is set in the indoor unit main body 1, the filter upper part is inserted into the filter holding means 24 from the filter guide 8, and the filter 4 is disposed below the suction port 2. At this time, the distance x between the boxes 10 and 11 is set to be slightly larger than the thickness y of the thickness of the lateral rib 21 and the thickness of the filter. It is possible to set the filter 4 smoothly without generating a large friction with the motor 11. The filter 4 is set with the surface on which the lateral ribs 21 are formed as the surface, and this surface is facing up.

  FIG. 10 is a schematic cross-sectional view showing the state of both boxes and the filter when the filter 4 is set in the indoor unit body 1. In the filter 4, horizontal ribs 21 are formed at substantially the same interval z as the width of the boxes 10 and 11 (the distance between the opening end faces 10a and 11a of the dust removal box). As a result, it is possible to close the gap 18 by positioning the lateral ribs 21 in the two gaps 18 formed in the box body 16. Thus, it becomes possible to form the cylindrical box body 16 without a gap with the front side box 10, the back side box 11, and the horizontal rib 21 interposed therebetween.

  In the present embodiment, the interval x is set to be slightly larger than the thickness y of the thickness of the lateral rib 21 and the thickness of the filter, but this may cause a slight warp or the like generated in the filter. This is for smooth insertion of the filter 4 in consideration. When the suction fan 12 is operated, the inside of the flow path 17 becomes negative pressure, and the dust removal boxes are in close contact with each other. It is possible to obtain the same suction force as when approximately the same is set.

  Next, the case where the filter 4 is cleaned with the filter cleaning device having the above-described configuration will be described. First, when the filter 4 is set in the indoor unit body 1 and the air conditioner is operated, air is sucked from the suction port 2 and is in the air on the surface of each section 4a of the mesh filter 19 divided by the lateral ribs 21. Dust A adheres.

  The indoor unit body 1 is provided with a control means including an input circuit, a CPU, a memory, and an output circuit. For example, when it is determined that the operation time of the air conditioner has reached a predetermined time, When it is determined that the surface of the filter 4 is dirty based on the detection result of the dirt detecting means such as the filter, the operation of the suction fan 12 and the moving means is controlled to clean the filter.

  Specifically, first, the moving means is operated, and the filter 4 is moved in the vertical direction by the interval z between the horizontal ribs 21 and stopped as shown in FIG. At this time, since there is a gap x between the front side box 10 and the back side box 11, the front side box 10 can move the filter 4 without contacting the dust A attached to the surface of the filter 4. it can. In this way, the section 4 a that was initially adjacent to the flow path 17 can be put into the flow path 17, and the lateral rib 21 can be positioned in the gap 18 of the box body 16.

  Next, the suction fan 12 is operated, and air is sucked from the vent 15 which is the inlet of the flow path 17 to the suction fan 12. As a result, an air flow having a high flow velocity is generated in the flow path 17, and the dust A attached to the surface of the section 4a is blown off to remove the dust. The dust A removed from the section 4a can be collected by installing a dust collection pack between the flow path 17 and the suction fan 12, or can be exhausted from the suction fan 12 to the outside. Thereafter, the filter 4 can be cleaned for each section 4a by repeating the above operation.

  When cleaning the last section 4a, the filter 4 is in the most moved state, but the filter 4 is bent and held in the filter holding means 24, so the filter 4 is not exposed to the outside of the indoor unit. There is no risk of losing aesthetics. When the cleaning of the last section 4a is completed, the filter 4 is moved to the original position by the moving means.

  In the present embodiment, one end side in the longitudinal direction of the box body 16 constituted by the front side box 10 and the back side box 11 is the vent 15 that is open to the whole surface, but the opening area of the vent 15 may be reduced. Is possible. In this case, the flow velocity of the air flowing through the flow path 17 can be increased, and dust attached to the filter surface can be efficiently removed.

  Furthermore, although the horizontal ribs 21 formed on the surface of the filter 4 are formed at substantially the same interval z as the widths of both the boxes 10 and 11, it is also possible to form them at intervals that equally divide the interval z. For example, as shown in FIG. 11, the lateral ribs 21 can be formed at intervals of z / 2. In this case, the filter may be moved by the interval z or may be moved by the interval z / 2.

  Moreover, in this embodiment, although the horizontal indoor unit was demonstrated, it is also possible to apply to a vertical type. Moreover, although this embodiment demonstrated the separate side air conditioner, of course, an integrated air conditioner may be sufficient.
