Description

  The present invention relates to an air conditioner that cleans a filter body attached to an air conditioner and reliably performs the processing.

  A conventional air conditioner of this type is known as shown in FIG. 7 (see, for example, Patent Document 1).

  FIG. 7 is a cross-sectional view of an air conditioner equipped with the conventional air conditioner cleaning device described in Patent Document 1. In the indoor unit body 1, a heat exchanger 2, a suction port 3 for taking in indoor air, a belt-like filter body 4 provided between the heat exchanger 2 and the suction port 3, and this filter A drive shaft 6 and a driven shaft 7 in which a body 4 is stretched; a servo motor 5 that rotationally drives the drive shaft 6; an air conditioner cleaning device 8 that removes dust collected by the filter body 4; A fan 10 is provided which sucks indoor air from the suction port 3 and blows out heat-exchanged air into the room through the heat exchanger 2 and from the blowout port 9.

  The air conditioner cleaning device 8 includes a rotary cleaning body 11 including a rotor 11a and a brush-like cleaning body 11b provided in the longitudinal direction of the outer periphery of the rotor 11a, and a drive for driving the rotary cleaning body 11 to rotate. Means (not shown), an exhaust pipe 13 communicating with the suction port 3 and having the rotary cleaning body 11 and having a discharge port 12, and a dust discharge fan 14 provided in the exhaust pipe 13; It is composed of

  The operation and action of the conventional air conditioner configured as described above are as follows. For example, when the indoor unit main body 1 is in a cooling operation, indoor air flows from the suction port 3 by the fan 10, reaches the heat exchanger 2 through the filter body 4, is cooled there, and cold air is discharged from the blowout port 9. It is blown into the room. Dust contained in the indoor air to be sucked is collected by the filter body 4 and deposited on the surface of the filter body 4. If dust accumulates on the surface of the filter body 4, air pressure loss of air increases and heat exchange efficiency decreases, so that dust on the filter body 4 can be removed periodically or as necessary. Driving is required.

In the dust removal operation, the servo motor 5 is operated to rotate the drive shaft 6 to continuously move the belt-like filter body 4, while rotating the rotary cleaning body 11 and the dust discharge fan 14 in the meantime. In operation, the dust on the filter body 4 is scraped off by the cleaning body 11 b of the rotary cleaning body 11, and the scraped dust is sucked by the dust discharge fan 14 and discharged to the outside through the discharge port 12. It has become so.
JP-A-6-74521

  However, when the dust is discharged, the dust suction fan 14 is rotated at a high speed, so that there is a problem that the noise is loud and the dust goes directly to the outdoors. Further, since the dust is directly discharged to the outside from the discharge port 12, the dust is scattered especially in a neighboring house or the like that is built in the vicinity, and the outdoor air is dust. Nowadays, it is necessary to take measures to prevent environmental problems.

  Further, in the configuration of the conventional cleaning device for an air conditioner, since the rotary cleaning body 11 is disposed above the filter body 4, dust captured by the filter body 4 is moved when the filter body 4 is moved. The vibration generated in the liquid drops before contacting the rotary cleaning body 11 and accumulates on the servo motor 5 side, making it difficult to dispose of dust or sticking to the servo motor 5 and possibly causing a failure. There was no problem.

  The present invention is for solving the above-described conventional problems, and provides an air conditioner that is hygienic, low noise, and easy to dispose of dust while maintaining the conventional dust scraping performance. For the purpose.

  In order to solve the above-described conventional problems, the air conditioner of the present invention is directed to a body case having a suction port and an exhaust port that guides outside air containing floating dust in the room from the suction port to the exhaust port. A filter body for forming dust passages and comprising a filter material for capturing floating dust in the passage air passages and a frame body for holding the outer periphery of the filter material, and collected by the filter body A dust removing body for removing dust, and a blower for discharging the outside air into the room through the exhaust port; a dust storage room for storing the dust from the dust removing body is provided on one side of the filter body; and a motor or the like It is characterized in that the dust in the storage chamber is moved to one side of the storage chamber by a moving means using as a drive source. Accordingly, the dust attached to the filter body is surely swept away by the dust removing body, and the dust stored in the dust storage chamber is moved to one side of the dust storage chamber by the moving means, so that the dust is easily put together. Because it can be stored, it can be reliably treated without scattering when dust is discarded. In addition, by increasing the size of the dust storage space, the number of dust treatments can be greatly reduced, which improves usability and prevents the dust from being discharged outdoors. Since no fan is required, no noise or vibration is generated outdoors.

  According to a second aspect of the present invention, there is provided an air conditioner in which a passing air passage is formed in the main body case having a suction port and an exhaust port for guiding outside air containing indoor floating dust from the suction port to the exhaust port. A filter material for collecting dust, a filter body for collecting dust comprising a frame body that holds the outer periphery of the filter material, a dust removing body for removing dust collected in the filter body, and the outside air And a blower for discharging the dust from the exhaust port into the room, a dust storage chamber for storing dust from the dust removing body is provided on one side of the filter body, and the dust storage chamber has a drive body including a motor or the like. To provide a rotational drive for moving the dust, to move the dust in the storage chamber to one side of the storage chamber by the rotary drive, and to compress the dust to a predetermined pressure and then push it out of the dust storage chamber. Has characteristicsTherefore, the dust attached to the filter body is surely swept away by the dust removing body, and the dust stored in the dust storage chamber is constituted by the rotational driving body, for example, the rotational driving body is configured by the spiral fins. The dust is pushed onto the fins and can be moved to one side of the dust storage chamber, and can be minimized by compressing the dust to a predetermined pressure, so that the dust can be easily put together. Because it can be done, it can be reliably processed without scattering when dust is discarded. In addition, by increasing the size of the dust storage space, the number of dust treatments can be greatly reduced, which improves usability and prevents the dust from being discharged outdoors. Since no fan is required, no noise or vibration is generated outdoors.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a dust storage chamber for storing and storing the dust pushed out from the dust storage chamber is detachably provided on one side of the dust storage chamber. The dust storage chamber is characterized in that it can be taken out from one side of the main body case. Therefore, during the dust treatment, the dust storage chamber can be directly carried to a trash box or the like, so that dust can be prevented from scattering. In addition, by increasing the volume of the dust storage chamber, the number of dust disposals can be significantly reduced and the usability can be improved.

  According to the first aspect of the present invention, dust attached to the filter body can be reliably collected and discharged to the outside in a sanitary manner. Further, in the invention of claim 2, for example, by configuring the rotary drive body with spiral fins, dust can be pushed to the spiral fins and moved to one side of the dust storage chamber. Since the amount of dust that can be accommodated can be increased, it is not necessary to frequently discharge the collected dust to the outside. Furthermore, in the invention of claim 3, the collected dust can be easily taken out from the air conditioner.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an air conditioner according to the present invention, and FIG. 2 is a schematic sectional view of the center of the air conditioner shown in FIG.

  In FIGS. 1 and 2, reference numeral 20 denotes an air conditioner according to the present embodiment, which is a suction port 21 for taking in indoor air on the front surface, an exhaust port 22 for discharging air below the front surface, and an air suction port 21. A passage air passage 23 for moving from the exhaust port 22 to the exhaust port 22 is provided. Further, in the passage air passage 23, in order from the upstream side, a filter body 24 for capturing the suspended dust contained in the indoor air, a heat exchanger 25 for exchanging the indoor air, and the indoor air for the main body case A blower 26 is accommodated that is sucked from the suction port 21 provided in 49, passes through the heat exchanger 25 and is discharged from the exhaust port 22. Further, the main body case 49 is provided with a dust take-out box 38a of a dust storage chamber 31 to be described later. The dust take-out box 38a can be taken out by grasping the handle 38 and pulling it forward, and collected in the dust take-out box 38a. Dust can be discharged to the outside.

  The filter body 24 is a belt-like member made up of a filter material having a large number of small-diameter holes and a frame body that holds the outer periphery of the filter material. The filter body 24 spans the upper rotating shaft 27a and the lower rotating shaft 27b, By actuating the drive device 28 connected to the shaft 27a, it rotates in the direction of arrow A. A dust storage device 30 including a dust removing body 29 that is in contact with the filter body 24 is installed below the lower rotary shaft 27b. Further, for the purpose of peeling off dust adhering to the dust removing body 29, a second dust removing body 50 formed in a comb shape is provided at a position where the dust removing body 29 is difficult to be inserted.

  FIG. 3 is an explanatory view showing the internal structure of the dust container 30. The dust storage device 30 contains the dust removing body 29, but is omitted in FIG. 3 for ease of explanation. FIG. 4A is a perspective view showing the entire dust storage device 30, and FIG. 4B is a perspective view of the dust storage chamber 31. The dust storage device 30 is installed below the filter body 24, and the longitudinal direction is longer than the entire width of the filter body 24.

  Then, after the dust captured by the filter body 24 is reliably removed by the dust removing body 29 over the entire width, the dust adhering to the dust removing body 29 is peeled off from the dust removing body 29 by the second dust removing body 50, and the dust is taken in. It moves from the mouth 32 into the dust storage case 33. The dust storage device 30 for storing dust has a horizontally long dust intake port 32, a hollow cylindrical dust storage case 33 communicating with the dust intake port 32, and is rotatable over the entire width of the dust storage case 33. And the outer periphery of the shaft center 34 so that the outer diameter of the shaft center 34 is close to the inner diameter of the dust storage case 33, and the dust is rotated spirally to one side of the dust storage case 33. The dust storage chamber 31 includes a fixed spiral fin 35, a drive body 36 that rotates the spiral fin 35 at a predetermined speed, and a dust inlet 37 that is detachably provided on one side of the dust storage case 33. ing.

  The distance between the fins constituting the spiral fin 35 is such that the amount of dust taken in from the dust inlet 32 gradually increases toward one side of the dust storage case 33, so that the dust storage chamber 31 side becomes wider L> l. In the design, the dust can be smoothly moved to the dust storage chamber 31 side.

  The dust storage chamber 31 stores the dust carried by the above-described spiral fins 35. However, the dust storage chamber 31 is detachable from the front surface of the main body case 49. It is possible to easily discharge the dust collected in the dust storage chamber 31 to the outside.

  The dust storage chamber 31 is provided with a movable plate 40 urged toward the dust inlet 37 by a spring 39, and the dust sent by the spiral fin 35 gradually moves the movable plate 40 to the dust inlet 37. It is configured to push to the opposite side. When the movable plate 40 comes into contact with the sensor 41, the pusher driving device 43a installed on the pusher insertion opening 42 side of the dust storage chamber 31 operates to act to push the pusher 43b to the dust 38 side. . Therefore, by compressing the dust to a predetermined pressure, the minimum capacity can be achieved, and the amount of dust that can be stored in the dust storage chamber 31 can be increased. Therefore, it is necessary to frequently discharge the collected dust to the outside. There is no convenience. Further, since the dust is compressed and solidified when the dust is discharged, it can be easily discarded.

  FIG. 5A is a perspective view showing the positional relationship between the dust removing body 29 and the filter body 24, and FIG. 5B is a perspective view showing the configuration of the dust removing body 29. As shown in these drawings, the dust removing body 29 is configured by winding a brushed cloth 45 composed of brush bristles 45 a and a base cloth 45 b on which the brush bristles 45 a are planted around a shaft body 44. Bearings 46 a and 46 b are installed on both sides of the shaft body 44. Further, the brush bristles 45a of the dust removing body 29 are brought into contact with the filter material having a large number of small-diameter holes of the filter body 24 to remove dust adhering to the filter material. The dust removing body 29 may be configured to rotate by being driven by the driving of the filter body 24 described above, but the dust removing body 29 is rotated by connecting a driving body (not shown) to either of the bearings 46a and 46b. It can also be set as the structure to make.

  As described above, the dust adhering to the dust removing body 29 is peeled off by the comb-like second dust removing body 50 that is installed so as to be hard to be inserted into the brush hair 45a of the dust removing body 29. The position where the body 50 is installed differs depending on the rotation direction of the dust removing body 29. For example, in FIG. 2, the second dust removing body 50 is installed at an obliquely lower right side with respect to the dust removing body 29, but in this case, the rotational direction of the dust removing body 29 is a direction against the progress of the filter body 24, That is, dust can be collected efficiently by turning counterclockwise. On the contrary, when the dust removing body 29 rotates in the direction driven by the drive of the filter body 24, that is, in the clockwise direction, the second dust removing body 50 may be installed at an obliquely lower left side of the dust removing body 29.

  FIG. 6 is an explanatory diagram of a control device in the air conditioner of the present invention. 47 is a control body for controlling the operation of the blower 26, the drive device 28, the pusher drive device 43a, and the drive body 36, and is housed in a control room (not shown) of the air conditioner 20. The control body 47 is controlled by a remote control body 48 having a switch or the like.

  When operated by the remote control body 48, the blower 26 is operated, indoor air containing floating dust enters through the suction port, and only the dust is collected by the filter body 24, and the clean air that has passed passes through the heat exchanger. The heat energy is deprived while passing through 25, passes through the blower 26, and the clean air is discharged into the room from the exhaust port. When the remote control body 48 is turned off after a lapse of a predetermined time after these operations, the control body 47 operates the driving device 28 to rotate the filter body 24 or the dust removing body 29 for a predetermined time and stop. As a result, the dust remover 29 forces the dust captured by the filter body 24 to enter the dust intake 32 of the dust storage device 30 disposed over the entire width of the filter body 24. At this time, the operation of the blower 26 is stopped, that is, since the suction force is not working, the dust removing body 29 can easily remove the dust from the filter body 24.

  Thereafter, the control body 47 operates the driving body 36 for a predetermined time, whereby the spiral fin 35 rotates, and the dust from the dust inlet 32 is rotated toward one side of the dust storage case 33. At this time, the amount of dust from the horizontally long dust inlet 32 gradually increases toward one side of the dust storage case 33. In order to smoothly move these dusts, the pitch of the spiral fins 35 is gradually increased. To be wide. Further, the spiral fin 35 is repeatedly operated, so that the dust moved to one side of the dust storage case 33 is gradually compressed, and the volume can be made compact.

  Furthermore, by providing the dust storage chamber 31 on one side of the dust storage case 33, a large amount of dust can be stored, the number of times of dust processing can be significantly reduced, and the dust storage chamber 31 can be detachably formed. In particular, in the case of an air conditioner attached to a high place in an indoor wall, clean processing is possible without dust scattering during dust processing. In addition, since the driving body 36 is stopped when the driving device 28 is operated, noise and vibration are reduced.

  As described above, the air conditioner according to the present invention can reliably store the dust adhering to the filter body in the dust storage chamber and easily discharge the dust accumulated in the dust storage chamber to the outside. Can be used for various air conditioners.
