Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to an air supply and exhaust system used in a combustor.

(B) Conventional technology Conventionally, this kind of equipment is generally equipped with an air supply/exhaust connection pipe attached to a mounting hole in a wall, etc., and an air supply/exhaust pipe that communicates with this pipe inside the mounting hole, with the air supply/exhaust pipe facing outdoors. An air supply hole and an exhaust hole were provided, and the connection pipe had a protruding connection port for a duct to the combustor (see Japanese Utility Model Publication No. 53-34584). To fix the connecting tube and the supply/exhaust tube, fix the connecting tube to a wall etc. on the indoor side.
The intake and exhaust pipes are slidably inserted into the connecting pipe. Therefore, in this case, since the connection port of the connection tube always protrudes toward the indoor side, it becomes a nuisance and is unsightly in the summer when the combustor is not used. In particular, when a panel is fixed to a sash window or the like and attached to the mounting hole there, the window cannot be completely closed because the connection port protrudes, and a special lock has to be prepared.

(c) Problems that the invention aims to solve This invention was made in view of the various problems mentioned above, and is fixed to a wall etc. with the mounting hole penetrated so that it does not protrude into the room. The object of the present invention is to provide an air supply/exhaust device which solves the above-mentioned problems by attaching an air supply/exhaust connection pipe provided with a connection port to the air supply/exhaust pipe from the indoor side so as to be freely insertable and removable.

(d) Means for solving the problem The present invention integrates the outer supply cylinder and the inner exhaust pipe to form a double cylinder shape, and penetrates the mounting hole in the wall or window panel so that the tip of the cylinder can be fixed. An air supply/exhaust pipe whose portion protrudes outdoors, an outer air supply connection pipe, and an inner exhaust connection pipe are integrated to form a double cylinder shape, and one end of the air supply/exhaust pipe is connected to the air supply/exhaust pipe. and an air supply/exhaust connection cylinder provided with a plurality of connecting ports, each of which is connected to the air supply/exhaust connection cylinder. A plate is fixed around the indoor side of the mounting hole and held on a wall or window panel, while the supply/exhaust connection tube is detachably attached to the supply/exhaust tube from the indoor side.

(E) Function This air supply and exhaust system is used by inserting the air supply and exhaust connection tube from the indoor side into the air supply and exhaust tube that is fixedly fixed to a wall etc. while penetrating the mounting hole, but when not in use, the air supply and exhaust Even when the connecting pipe is separated from the supply/exhaust pipe and the supply/exhaust pipe is fixedly held on a wall or the like, the supply/exhaust pipe hardly protrudes toward the indoor side.

(f) Examples Examples of the present invention will be described below based on the drawings. The embodiment shown in Figs. 1 and 2 is the mounting hole 1 of wall A.
It uses X is a supply and exhaust pipe formed into a double cylinder by airtightly partitioning the outer supply cylinder 2 and the inner exhaust pipe 3 and integrating them, and the tip of the inner exhaust pipe 3 is connected to the inner surface of the supply cylinder 2. An exhaust hole 4 and an air supply hole 4' are bored at two places in the supply cylinder 2, which is fixed to the cylinder and partitioned here. This supply and exhaust pipe X has a screw 5 formed in about half of the outer circumference of the supply cylinder 2, and an annular end plate 6 having a predetermined slope on the outside of the indoor opening end of the supply cylinder 2. are integrally welded together, and holes for screws are bored around the annular end plate 6. Further, the exhaust pipe 3 has its indoor opening end substantially flush with the annular end plate 6. In this way, the above-mentioned supply and exhaust pipe X is inserted into the mounting hole 1 from the indoor side.
The annular end plate 6 is inserted into the gasket 7 and passed through.
It is brought into contact with the wall A surrounding the mounting hole 1 via the hole 1 and fixed with screws as necessary. At this time, the air supply and exhaust pipe X is tilted downward toward the outdoor side using the inclined surface of the annular end plate 6.

On the outdoor side, another annular end plate 8 having a similar slope is fitted into the supply cylinder 2 via a gasket 9 and brought into contact with the wall A around the mounting hole 1, and then a pressure ring 10 is supplied from the outside. It is screwed onto the outer periphery of the cylinder 2, and the end plate 8 is pressed by this screwing force, and the supply/exhaust pipe X is clamped into the mounting hole 1. Reference numeral 11 denotes a sleeve that expands and contracts in three stages, and its base end is removably attached to the annular end plate 6 with screws, etc., and the sleeve 11 is attached to the supply cylinder 2 in the mounting hole 1.
Surround and protect the outer periphery of.

On the other hand, the supply/exhaust connection tube Y for connecting the combustor (not shown) to the supply/exhaust tube X also airtightly partitions the outer air supply connection tube 12 and the inner exhaust connection tube 13 from each other. By integrating it, it has a double cylindrical shape, and one end side thereof has a connection port 1 connected to the front air supply connection tube 12 and the exhaust connection tube 13, respectively.
4 and 15 project outward, and other connection ports 16, which are provided in advance in consideration of various connection directions, are provided with lids 17. Furthermore, the exhaust connection tube 1
3, the other end opening side is connected to the air supply connecting tube 12
A screw 18 is formed on the other end opening side of the air supply connecting cylinder 12 to be screwed into the screw 5 of the air supply cylinder 2. Thus, during the season when the combustor is used, the supply/exhaust connection tube Y is inserted into the supply/exhaust tube , the air supply connecting tube 12 is screwed into the supply cylinder 2 with screws 5 and 18. Finally, each connection port 1
4, 15 and the combustor are connected with flexible metal pipes or resin pipes (not shown).

In seasons such as summer when the combustor is not used, remove the connection between the combustor and the connection ports 14 and 15, rotate the supply/exhaust connection pipe Y and pull it out from the supply/exhaust pipe X, and replace the lid 19. Fits into the supply and exhaust pipe X to hide its opening.

Next, an example of attaching this device to a window such as a sash will be explained based on FIGS. 4 and 5. First, a window panel B is attached to the window frame 20 at a distance 22 on the outside side of the glass door 21. The glass door 21 is fixed, and in this state, the glass door 21 can be freely opened and closed. After removing the sleeve 11 from the supply/exhaust tube do. Of course, the supply and exhaust pipes X are tilted outward and downward. The annular end plate 6 is a window panel B
Since it is in close contact with the space, it does not protrude beyond a distance of 22.
Therefore, even in this state, the glass door 21 can be freely opened and closed, and the glass door 21 can be locked in the closed state with the lock 23 attached thereto in advance.

In the season when the combustor is used, such as winter, the glass door 21 is opened by the width of the window panel B, and the supply/exhaust connection pipe Y is inserted into the supply/exhaust pipe X and connected by screwing.
The respective connection ports 14 and 15 of this supply/exhaust connection pipe Y are connected to the combustor using appropriate pipes.

When the combustor is not used, the pipe, supply/exhaust connection pipe Y
is removed and a cover 19 is fitted to the supply/exhaust tube X instead, but this cover 19 may be removed and the supply/exhaust tube X may be used for ventilation if necessary. In this state, the glass door 21 can be fully closed and locked using the lock 23 as described above.

(g) Effects of the invention Since the invention is as described above, when the combustor is not in use, the supply/exhaust connection pipe can be detached from the supply/exhaust pipe while the supply/exhaust pipe remains attached to the wall or window panel, and, Even if the air supply and exhaust pipe remains attached to the wall or window panel, the annular end plate can be the only element that protrudes into the room. Therefore, even when the pipe is not in use, such as during summer, the air supply and exhaust pipe can remain attached to the wall, etc., and since there are almost no obstacles to the indoor space, it does not get in the way. In particular, when a window panel is used to attach an air supply/exhaust pipe to a window, the glass door can be fully closed by simply removing the air supply/exhaust connection pipe from the air supply/exhaust pipe.
