  The container body 13 is formed of a cylindrical member made of a transparent member such as a transparent acrylic resin, and the dust collecting state can be visually confirmed from the outside. Further, the container body 13 is inserted with the tip of the dust hose 4 into the container body 13 at an appropriate position on the peripheral surface close to the upper end opening closed by the upper lid 14, and the dust hose 4 is connected from the indoor unit 1 to the container body 13. An inlet 16 is formed for introducing air containing dust discharged outside through the chamber body 13. For example, a rubber O-ring is interposed between the peripheral edge of the inlet 16 formed on the peripheral surface of the container body 13 and the outer periphery of the dust exhaust hose 4 inserted therein or filled with a joint material. It is desirable to prevent a rainwater or the like from invading into the container body 13 through the gap by performing a sealing process.

  The introduction port 16 may be provided in the upper lid 14 that closes the upper end opening, instead of being provided on the peripheral surface near the upper end opening of the container body 13. As described above, the introduction port 16 may be provided on either the container body 13 or the upper lid 14, but is desirably provided at a position away from the lower lid 15 provided with a filtration exhaust port 19 described later. By providing the introduction port 16 at a position away from the lower lid 15 provided with the filtration exhaust port 19, the air introduced from the introduction port 16 to the inside of the container body 13 is discharged from the filtration exhaust port 19 to the outside. In the meantime, it is possible to effectively suppress inconveniences such as convection inside the container body 13 and picking up dust.

  The upper lid 14 is formed by processing a member such as metal into a circular cap shape covering the upper end opening of the container body 13 and the peripheral wall in the vicinity of the opening, and closes the upper end opening of the container body 13. And fixed to the container body 13 by, for example, a thumbscrew 17 or the like. By covering the upper end opening of the container main body 13 and the peripheral wall in the vicinity of the opening with the upper lid 14 as a cap shape, it is possible to effectively prevent rainwater and the like from entering the inside from the upper end opening of the container main body 13. It is possible to avoid the problem that the dust collected inside contains moisture and causes mold and odor. In addition, by adopting a structure in which the upper lid 14 is fixed to the container main body 13 with the thumbscrew 17, the upper lid 14 can be easily attached to and detached from the container main body 13 without using a tool. Cleaning can also be performed easily.

  Similarly to the upper lid 14, the lower lid 15 is formed by processing a member such as a metal into a circular cap shape that covers the lower end opening of the container body 13 and the peripheral wall near the opening. A filtration exhaust port 19 covered with a filtration member 18 is formed on the bottom surface facing the portion. The filtration exhaust port 19 captures dust contained in the air introduced into the container body 13 from the introduction port 16 by the filtration member 18 and discharges clean air that has passed through the filtration member 18 to the outside of the container body 13. To do. As the filter member 18, any member that can capture dust and allow only air to pass, such as a metal mesh material or a commercially available exhaust filter, can be used. What is necessary is just to select the optimal fineness of this filter member 18 according to the capability of the suction device 9 of the indoor unit 1, the magnitude | size of dust, etc. FIG. The filtration member 18 may be formed as a separate member from the lower lid 15 and may be attached to the lower lid 15 so as to cover the filtration exhaust port 19 or may be formed as an integral member with the lower lid 15. May be.

  The lower lid 15 is attached to the container main body 13 such that the filtration exhaust port 19 covered with the filtering member 18 faces the lower end opening of the container main body 13. 13 is fixed. By adopting a structure in which the lower lid 15 is fixed to the container main body 13 with the thumbscrew 17 in the same manner as the upper lid 14, the lower lid 15 can be easily attached to and detached from the container main body 13 without using a tool. The operation of removing dust collected in the container main body 13, cleaning of the inside of the container main body 13, cleaning of the filter member 13, and the like can be easily performed.

It is desirable that the central portion 18c is formed continuously through the portion 18b and has a center portion 18c raised from the peripheral edge portion 18a. When the filtering member 18 has the shape as described above, even if rainwater enters the inside of the container body 13, the rainwater that has entered the inside of the container body 13 travels along the inner wall of the container body 13 and has a peripheral edge of the filtering member 18. It reaches the portion 18 a and is discharged from the container main body 13 through the filtration exhaust port 19 from here. Therefore, the central portion 18c of the filtering member 18 can effectively exhibit a filtering function that allows only clean air to pass while capturing dust without being affected by rainwater that has entered the inside of the container body 13.

  As described above in detail with specific examples, the air conditioner to which the present invention is applied includes dust from the indoor unit 1 in the piping duct 3 that connects the indoor unit 1 and the outdoor unit 2. A dust exhaust hose 4 for discharging air to the outside is arranged, the tip end side of the dust exhaust hose 4 is branched from the pipe duct 3, and the dust receiving device 10 is connected to the tip thereof. The dust receiver 10 captures dust in the air discharged from the indoor unit 1 to the outside by the filter member 18 and collects it inside the container body 13, and clean air from the filter exhaust port 19 to the outside. Since it is discharged, the outdoor can be kept clean.

  Further, the dust receiving device 10 connected to the tip of the dust exhaust hose 4 has a filtration exhaust port 19 covered with a filtration member 18 formed in the lower lid 15 detachably attached to the container body 13. The filter member 18 can be easily cleaned by removing the lower lid 15 from the container main body 13 and the maintainability is improved.

  The embodiment described above is an example of application of the present invention, and the present invention is not intended to be limited to the contents described in the above embodiment, and departs from the spirit of the present invention. Various modifications can be made without departing from the scope. For example, in the dust receiving device 10 described above, the upper lid 14 and the lower lid 15 are fixed to the container main body 13 by the thumbscrews 17, but the structure for fixing the upper lid 14 and the lower lid 15 to the container main body 13 is particularly limited. Instead of this, a fastening member other than the thumbscrew 17 may be used. Also in this case, if a fastening member capable of attaching and detaching the upper lid 14 and the lower lid 15 without using a tool is used, maintenance work such as dust removal and cleaning inside the container body 13 and cleaning of the filtering member 18 can be easily performed. Can do. It is also effective to connect the upper lid 14 and the lower lid 15 to the container body 13 by a hinge mechanism or the like so that the upper lid 14 and the lower lid 15 do not fall off when opened. Further, the upper lid 14 and the lower lid 15 may be fixed to the container main body 15 by fitting or screwing the upper lid 14 and the lower lid 15 to the container main body 13.

It is desirable.

  In the dust receiver 10 described above, the container body 13 is a cylindrical member that opens at the upper end and the lower end, and the upper end opening of the container body 13 is closed by the upper lid 14 and the lower end opening is closed by the lower lid 15. However, as shown in FIG. 7, the container main body 13 may be a bottomed cylindrical member that opens only at the lower end, and the container structure may be such that only the lower end opening of the container main body 13 is closed by the lower lid 15. In this case, as compared with the structure in which the upper end opening of the container body 13 is closed by the upper lid 14, the cleaning work on the upper end side inside the container body 13 is somewhat complicated, but the water tightness can be kept better. Benefits are gained. Further, in the dust receiving device 10 described above, the entire container body 13 is configured with a member through which the inside can be seen through. However, a part of the container body 13 is formed with a member through which the inside can be seen through, and the container body can be formed from this part. It is good also as a structure which can confirm the collection state of the dust in 13 inside.

  Further, the indoor unit 1 described above is configured to suck and remove dust adhering to the surface of the air filter 5 by the suction nozzle 6 connected to the suction device 9 as an automatic filter cleaning mechanism for automatically cleaning the air filter 5. However, the automatic filter cleaning mechanism included in the indoor unit 1 is not limited to the above-described example. For example, a configuration in which dust is removed by contacting the air filter 5 while rotating or vibrating a brush, Any generally known configuration such as a configuration in which the air filter 5 itself is vibrated to remove dust can be employed.

  Further, the dust discharged from the indoor unit 1 through the dust hose 4 and collected by the dust receiving device 10 is removed from the air filter 5 by the automatic filter cleaning mechanism of the indoor unit 1. Not limited to. That is, the dust receiver 10 is capable of collecting all dust discharged from the indoor unit 1 to the outside through the dust hose 4.
