  However, in Patent Document 1, since a branch box is newly arranged inside the outlet cover, and the on-off valve device is incorporated inside the branch box, the narrow space in the outlet cover and the narrower space such as the branch box can be obtained. Since the on-off valve device is attached, there is a problem that the workability of attaching the on-off valve device and the branch box is deteriorated.

  In view of the above, an object of the present invention is to provide an air conditioning apparatus and an exhaust pipe on / off valve mounting method that can improve the mounting workability.

  In order to achieve the above object, the present invention provides an air conditioner including an outlet cover that includes a refrigerant pipe and an exhaust pipe that are pipe-connected between an indoor unit and an outdoor unit and is attached to an outdoor wall. A support frame and an opening / closing valve supported by the support frame so as to be freely openable and closable at an opening formed by removing the lattice portion formed by a large number of slits formed in the cover body and removing the lattice portion; The on-off valve device is attached, and the on-off valve is closed by its own weight when the operation is stopped, and close to the rear end of the exhaust pipe so as to be opened by the exhaust pressure generated in the exhaust pipe during operation.

  In an air conditioner including a filter cleaning device including a suction fan that removes dust adhering to an air purification filter by using a suction force of air, and an exhaust pipe for exhausting air containing the sucked dust. Since the air exhausted from the exhaust pipe contains dust, if there is a lattice part with many insect repellent slits formed in the outlet cover, the dust in the exhaust will adhere to the lattice part. Then, there is a risk of closing the lattice portion. Therefore, an opening / closing valve device for repelling insects is required instead of the lattice portion or on the upstream side of the lattice portion.

  In order to place this on-off valve device in the lattice part that is no longer necessary as a part of the outlet cover, put a cutter around the lattice part to cut out the lattice part, or beat it with a screwdriver etc. to remove the lattice part, An on-off valve device is attached to the removed opening.

  As a result, it is not necessary to newly provide a branch box as in the prior art, and the on-off valve device is also installed in a relatively large space in the outlet cover, so that the mounting workability is improved.

  In this case, if an embodiment is adopted in which an opening is formed in the cover body of the outlet cover and the exhaust cover is detachably attached so as to cover the opening, the lattice portion is removed with the exhaust cover removed, The on-off valve device can be attached from the outside, and attachment workability can be improved.

Further, the present invention provides an air conditioner including an outlet cover that includes a refrigerant pipe and an exhaust pipe that pipe-connect an indoor unit and an outdoor unit and is attached to an outdoor wall, and the outlet cover is attached to the cover body. In order to exhaust the exhaust from the exhaust pipe to the outside, it has a lattice part in which a number of insect repellent slits are drilled, and a concave cut groove is provided around the lattice part to facilitate removal of the lattice part. An opening / closing valve device for repelling insects can be attached to the opening formed by removing the lattice portion along the cut groove, and the opening / closing valve device is in an operation stop state. It is attached to the rear end of the exhaust pipe so that it is closed by its own weight and opened by the exhaust pressure generated in the exhaust pipe during operation .

  According to the above configuration, since the on-off valve device is directly attached to the outlet cover, a conventional branch box is unnecessary, and the on-off valve device is installed in a relatively large space in the outlet cover. Mounting workability is improved.

  Here, the outlet cover includes a cover main body including the refrigerant pipe and the exhaust pipe, and an exhaust cover that covers an opening formed in the cover main body and forms an exhaust passage therein, and the exhaust cover is attached to the cover main body. On the other hand, it is detachably attached.

  According to this configuration, since the exhaust cover is detachably attached to the cover body, the on-off valve device can be easily attached.

Is rotated 90 degrees around the center of the exhaust pipe so that it can be always horizontal.

  According to the said structure, an exit cover can be set to either vertical installation or horizontal installation by the installation condition of the outdoor unit of an air conditioner. At this time, in order to close the on-off valve device by its own weight, the on-off valve device must keep its support shaft always in a horizontal posture. In order to satisfy this, it is set so that the on-off valve device can be attached to the opening even if it is rotated 90 degrees. If it does so, the on-off valve apparatus can respond to both vertical installation and horizontal installation of an outlet cover.

  The exhaust pipe may be connected to a ventilation device as shown in Patent Document 1, but is preferably connected to a suction fan of a filter cleaning device of an indoor unit. According to this configuration, when dust is removed from the filter that removes dust in the air using air suction force, even if dust is contained in the air, it is discharged without being clogged by the on-off valve. Can do.

    As described above, according to the present invention, the grid portion formed in the cover body of the outlet cover is removed, the opening / closing valve device is attached to the opening formed therein, and the opening / closing valve is closed by its own weight in the operation stop state. Since the exhaust pipe is brought into close contact with the rear end so as to be opened by the exhaust pressure generated in the exhaust pipe during operation, the workability of mounting the on-off valve device is improved as compared with the conventional case.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
