DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forced-supply / exhaust combustion apparatus for discharging combustion gas to the outside and supplying combustion air from outside.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Publication No. Hei 7-3152, an exhaust passage and an air supply are provided in a double pipe structure on the back side of an appliance body of a combustion apparatus. An air supply / exhaust pipe extending from the appliance body side is connected to a terminal section that constitutes a connection part of the supply / exhaust pipe, which is provided with a supply / exhaust pipe that penetrates a wall to form an exhaust path. And heating the air without polluting the indoor air.

[0003]

By the way, in this conventional apparatus, the terminal of the air supply / exhaust tube and the air supply pipe are inevitably provided.
Since the exhaust pipe is located on the back of the instrument body, the gap between the instrument body and the wall cannot be narrowed any more, and there is a problem that the space for installation becomes large and effective use of the space cannot be measured. There is also a problem that dust accumulates in the gap between this instrument body and the wall,
To prevent this, there is a method of attaching a cover or the like to the upper part, but a new problem that the number of parts increases and the cost increases.

[0004]

In order to solve the above-mentioned drawbacks, the present invention focuses on this point. In particular, the present invention relates to a double-pipe supply / exhaust cylinder for supplying exhaust gas after combustion and air supply for combustion. And a connection part between the exhaust pipe and the air supply pipe on the instrument body side of the supply / exhaust pipe is housed in a frame body of the instrument body.

[0005] In addition, by making the exhaust pipe extendable and contractable, it is possible to easily cope with a change in the position of the connecting portion that fluctuates depending on the installation conditions, and a reliable connection is always obtained.

Further, by providing a detachable cover frame at the frame portion facing the terminal portion, not only connection work at the time of installation but also maintenance can be easily performed and the usability is good.

Next, the operation of the embodiment of the present invention will be described. First, when installing the appliance, the appliance main body 13 and the supply / exhaust tube 1 are connected, and the supply / exhaust tube 1 is fixed to the wall 2.

Therefore, the cover frame 28 is removed from the frame body 14 to open the storage room 15 to secure a work space, and the two indoor-side supply / exhaust cylinders 1 are brought here to exhaust the terminal unit 10. An exhaust pipe 16 is connected to the port 11, and an air supply pipe 17 is connected to one of the air supply ports 12. In this state, the air supply / exhaust tube 1 may be inserted into the through hole 3 of the wall 2. Although the height of the hole 3 may be slightly different, the exhaust pipe 16 has a structure that can be freely moved up and down by fitting connection by a longer connection pipe 20 and an O-ring 21, and the air supply pipe 17 is also flexible. Since it is made of vinyl chloride, there is some room for up and down movement, and the height adjustment of the through hole 3 can be performed while being connected. It can be inserted into

Next, when the other divided outdoor air supply / exhaust tube 1 is inserted into the through hole 3 of the wall 2 from the outdoor side, the air supply / exhaust tube 1 is connected within the through hole 3 to be integrated, and After that, if the movable flange 41 is fixed with screws or the like while the wall 2 is sandwiched between the movable flange 41 and the fixed flange 42, the installation of the instrument body 13 and the attachment of the supply / exhaust cylinder 1 are completed. The cover frame 28 removed last is returned to the original state.

Therefore, since the terminal portion 10, which is the connection portion of the supply / exhaust tube 1 with the appliance body 13, is stored in the storage chamber 15 of the frame 14, the connection pipe is located between the wall 2 and the appliance body 13. Without this, the device main body 13 can be installed in close proximity to the wall 2 so that the installation space can be small, and the device main body 13 does not protrude greatly into the room, so that the space can be used effectively. Things.

On the other hand, when the operation switch 45 of the operation section 44 is turned on, the apparatus main body 13 turns on fuel supply means (not shown).
From the outside and the supply of combustion air from outside through the air supply path 5 of the supply / exhaust pipe 1 by driving the combustion fan 26, the burner 27 performs good combustion, and the combustion gas is red-hot. The tube 38 is heated, passes through the heat exchanger 18, and is discharged outside again through the exhaust path 4 of the supply / exhaust tube 1.
At this time, if the hot air fan 32 is driven, the indoor air is heat-exchanged by the heat exchanger 18 to become hot air, which is discharged from the outlet 19 to heat the room by hot air and to heat the heated red hot cylinder 3.
With the radiant heat of No. 8, it is possible to satisfactorily heat the indoor air without polluting it.

In this embodiment, the connection between the supply / exhaust tube 1 and the supply / exhaust tube 1 is described. However, the device body 13 and the supply / exhaust tube 1 are already connected at the time of shipment of the device.
At the installation location, only the adjustment of the alignment between the supply / exhaust tube 1 and the through hole 3 is performed, so that the installation work can be simplified.

[0027]

As described above, according to the present invention, there is no dead space between the wall and the appliance main body for connecting the air supply / exhaust tube which becomes a garbage pool, and the appliance main body is installed close to the wall. The space can be effectively used without taking up space, and the equipment itself does not protrude into the room.

Also, by making the exhaust pipe freely movable up and down, even if there is a slight difference in the position of the through hole, the position of the supply / exhaust cylinder can be easily adjusted, and the difference in the hole position can be flexibly handled. A reliable installation can be performed.

Further, by providing the cover frame, it is possible to secure a working space for connection work between the air supply / exhaust pipe and the appliance body and for maintenance work, which has an effect that work can be performed smoothly. It is.
