れる恐れがあつた。(Prior art and problems) Conventionally, as shown in Japanese Utility Model Application Publication No. 51-63242, a hook-shaped elastic locking piece is provided on the guide inner cylinder on the indoor side, and an elastic locking piece is provided on the air supply/exhaust cylinder on the outdoor side. Those provided with a protrusion that engages with the locking piece are difficult to remove once inserted. Also, instead of forming only one protrusion on the supply/exhaust cylinder, when inserting it, align the elastic locking piece with this position, insert it, rotate the supply/exhaust cylinder, and engage the protrusion with the elastic locking piece. There are some that are made to fit together, but once they are aligned, they can easily come off, so there is a risk of them becoming misaligned.

It is fixed to the main body 1 with screws. 10 is a spacer screwed to the air supply duct 8, and the distance between the wall 11 and the rear plate of the main body 1 is 35
mm. Reference numeral 12 denotes an elastic plate fixed by spot welding or the like at two 180° symmetrical positions on the upper and lower sides of the exhaust connection tube 4, and extends toward the tip of the exhaust tube connection portion 41, forming a hook-shaped elastic locking piece 121 at the tip. It has been done. A chamfered portion 122 is formed at the tip of the elastic locking piece 121, as shown in FIG. Reference numeral 13 denotes an air supply connection cylinder, which is composed of a cylindrical air supply cylinder connection part 131 that covers the outer periphery of the exhaust cylinder connection part 41, and a flange part 132 that is fixed to a sleeve fixing plate 15, which will be described later.
Reference numeral 14 denotes a sleeve that covers the outer periphery of the supply cylinder connecting portion 131 and is passed through a wall hole, and has a thread formed on the outer periphery. It is clamped and fixed. Reference numeral 16 denotes a wall hole sealing body, which has a closing part 161 that comes into contact with the wall surface through the seal packing 6, and a flange part that is screwed to the air supply data 8, and is a box body whose side peripheral surface is closed.

ぱるともう片方も同様にはずれるのである。 Next, the installation procedure for this configuration will be explained. First, the exhaust connection pipe 4 is screwed to the main body 1, and then the air supply data 8 to which the spacer 10 is attached is fixed to the main body. Next, the sleeve 14 and the air supply connection tube 13 are inserted into the sleeve fixing plate 15, and the air supply connection tube 13 is fixed with screws. Then, connect this assembly to the exhaust pipe connection part 41.
Insert it from the tip, then insert the wall hole sealing body 16, and tighten it together with the air supply data 8 with the screw 7. In this state, the main body 1 is inserted so that the sleeve 14 passes through the wall hole.
The spacer 10 and the wall hole sealing body 16 are pushed in until they come into contact with the wall. Thereafter, the inclined plate 17 is externally inserted into the sleeve 14 from outside, and the nut 18 is tightened to fix the inclined plate 17 and the sleeve 14. Finally, install the supply and exhaust pipe 19, and the supply cylinder 20.
Then, the exhaust pipe 21 is inserted into the respective connecting pipes 4 and 13 so as to be inserted thereinto. At this time, the part of the exhaust pipe 21 where the protrusion 22 is not formed is aligned with one of the elastic locking pieces 121 and inserted. One of the elastic locking pieces 121 rides over the protrusion 22 while being compressed by the protrusion 22. When the air supply and exhaust pipe 19 is rotated by an appropriate angle with the protrusion 22 inserted deeper than the elastic locking piece 121, both elastic locking pieces 1
The protrusion 22 is locked to the holder 21 and cannot be removed, and the installation work is now completed. If the wall 11 is thick, a longer supply and exhaust pipe 19 prepared separately is used.
When removing the air supply and exhaust pipe 19, pull it out while turning it. When the elastic locking piece 121 is turned and pulled, when the tip of the elastic locking piece 121 comes to the cut of the protrusion 22, the chamfered part 122 is guided by the slope of the protrusion 22 and rides on it, and the elastic locking piece 121 is compressed. Then, the elastic locking piece 1
One side of the 21 is disengaged, and if you turn it further and pull it, the other side will disengage as well.

である。(Effects of the invention) As described above, the present invention has a double pipe structure in which the exhaust connection pipe that communicates with the exhaust pipe of the appliance and the air supply connection pipe that communicates with the air supply pipe are inserted into a wall hole, and the same is provided from the outdoor side. In a device that externally connects an air supply and exhaust pipe with a double pipe structure, a plurality of elastic plates are provided on the outer surface of the inner cylinder of the connecting pipe, extending toward the tip of the connection part, and having a hook-shaped elastic locking piece formed at the tip. A chamfered portion is formed at the tip of the elastic locking piece, and a protrusion that engages with the elastic locking piece is formed at the end of the inner cylinder of the intake and exhaust pipe, and a cut is made in the protrusion. Therefore, it will not come off just by pulling it, or even if you align it and pull it, and when necessary, it can be removed with a simple operation of turning and pulling, which prevents tampering and makes attachment and removal work easier. It is possible to achieve both.
