The casing of the air conditioner 1 includes a frame 2 that is fixed to a wall surface in the room when the air conditioner 1 is installed, and a front grill 3 that is attached to the front side of the frame 2. The front grill 3 is formed with a plurality of suction ports 3a in the horizontal direction from the front surface to the upper surface.

  In the casing of the air conditioner 1, a filter device 11, a heat exchanger 5, and a blower fan 6 are provided. The filter device 11 is arranged so as to be bent along the inner surface of the front grill 3 and collects dust (substance) in the air sucked from the suction port 3a. Further, the filter device 11 has a cleaning function for removing the collected dust. The heat exchanger 5 is disposed further on the inner surface of the filter device 11, and is configured by connecting the front side heat exchanger 5a and the back side heat exchanger 5b in an inverted V shape. The heat exchanger 5 functions as a condenser (during heating operation) or an evaporator (during cooling operation) in the refrigerant circuit, and performs heat exchange with the sucked air. The ventilation fan 6 is arrange | positioned along the longitudinal direction of a casing inside the heat exchanger 5, and circulates air by the rotation. Further, an air outlet 8 provided with a horizontal flap 7 and a vertical flap (not shown) is formed below the front grill 3.

  Next, the operation of the air conditioner 1 will be described. As the blower fan 6 rotates, room air is sucked from the suction port 3 a of the front grill 3. The air sucked from the suction port 3 a passes through the filter device 11, and dust floating in the air is collected by the filter device 11. The air that has passed through the filter device 11 exchanges heat by contacting the heat exchanger 5. The heat-exchanged air is guided to the scroll portion 2 a formed on the frame 2 by the rotation of the blower fan 6 and is sent out from the blowout port 8. Thereby, the air conditioner 1 functions as heating or cooling.

  Next, the filter device 11 will be described. FIG. 2 is a schematic perspective view of the filter device 11, and FIG. 3 is a plan development view of the filter device 11. The filter device 11 is collected by a frame member 12 constituting an outer frame of the filter device 11, a filter material 13 for collecting dust, a sprocket 14 as a drive unit for moving the filter material 13, and the filter material 13. And a collecting device 15 that cleans the filter medium 13 by collecting dust.

  The filter medium 13 is comprised by the core material 13a which consists of a linear member of resin, and the some modification member 13b provided in the surface. The core material 13a is made of a bendable material and is connected in an annular shape. The modifying member 13b is made of a linear member that is bendable thinner than the core material 13a, and is fixed radially to the surface of the core material 13a by a method such as flocking. The filter medium 13 is disposed so that the modification member 13 b fills the air passage surface of the filter device 11, and is slidably supported by a plurality of supports 16 provided on the frame member 12. Dust in the passing air is mainly collected by the modifying member 13b.

  The sprocket 14 is provided so as to be rotatable with respect to the frame member 12 and is disposed so as to support the filter medium 13. When the sprocket 14 rotates, the filter medium 13 is moved in the axial direction of the core material 13a, and the filter medium 13 circulates while maintaining its arrangement. FIG. 4 shows a configuration in which the sprocket 14 moves the filter medium 13. 4A is a perspective view of the configuration, FIG. 4B is a cross-sectional view taken along line AA in FIG. 4A, and FIG. 4C is taken along line BB in FIG. 4A. It is sectional drawing. The sprocket 14 is configured to be driven to rotate about a rotating shaft 14a by a motor (not shown). In the sprocket 14, four tooth portions 14 c are formed on the outer peripheral surface 14 b that supports the filter medium 13. On the other hand, in the core material 13a of the filter medium 13, a plurality of engagement holes 13c are provided over the entire circumference of the core material 13a in accordance with the pitch of the tooth portions 14c of the sprocket 14. As the sprocket 14 rotates, the teeth 14c are sequentially engaged with the engagement holes 13c of the core material 13a, and the filter medium 13 is moved in the axial direction of the core material 13a. Here, the modification member 13b of the filter medium 13 is fixed at a position where it does not interfere with the sprocket 14 as shown in the figure.

  The collection device 15 is provided on the frame member 12 and is arranged so that the filter medium 13 passes when the filter medium 13 moves. Then, when the filter medium 13 passes through the recovery device 15, the dust collected by the filter medium 13 is recovered. FIG. 5 shows a cross-sectional view of the recovery device 15. Here, the solid line arrow in FIG. 5 indicates the direction in which the dust is guided. The collection device 15 includes a passage 15a through which the filter medium 13 passes, a plurality of contact portions 15b provided in the passage 15a, and a discharge port 15c that discharges dust. When the filter medium 13 passes through the passage 15a, the contact portion 15b comes into contact with the modification member 13b of the filter medium 13, so that dust attached to the modification member 13b is removed and the filter medium 13 is cleaned.

  The dust removed by the collection device 15 is stored in the storage unit 17 disposed so as to communicate with the discharge port 15 c of the collection device 15. The dust stored in the storage unit 17 is discharged outside through an exhaust duct 18 provided in the storage unit 17.

  In the first and second embodiments, dust removed by the collectors 15 and 25 is discharged to the outside through the storage unit 17 and the exhaust duct 18, but the storage unit 17 is configured to be detachable. Then, the user may collect the dust in the storage unit 17 collected by cleaning at an arbitrary timing.

  In the first and second embodiments, the sprockets 14 and 24 and the collectors 15 and 25 are provided in the frame members 12 and 22 to unitize the filter devices 11 and 21, but the sprockets 14 and 24 are connected to the frame member 12, It is good also as a structure which is not provided in 22, and it is good also as a structure which does not provide the collectors 15 and 25 in the frame members 12 and 22. FIG.

  -In 1st and 2nd embodiment, although the filter apparatuses 11 and 21 which concern on this invention are applied to the filter part of the air conditioner 1, you may apply to filter parts, such as an air cleaner. Moreover, you may apply not only to the filter part for air which collects dust but to the filter part used with respect to gases and liquids other than air.

  In the first and second embodiments, the filter devices 11 and 21 according to the present invention are used for cleaning the filter media 13 and 23. However, the filter devices 11 and 21 may be used for separating the substances in the fluid by sieving. Good. By collecting the substances collected by the filter media 13 and 23 by the collectors 15 and 25, the substances in the fluid can be separated.
