The present invention relates to a device for fixing an intake and exhaust pipe of a heating device that is installed in a heating device such as a gas boiler and an oil boiler to inhale air necessary for combustion from the outside together with the discharge of exhaust gas. The present invention relates to a device for fixing an intake and exhaust pipe of a heating device, which is simple to work and can be fixed to a wall or the like so as to completely prevent incomplete combustion and inflow of waste gas due to poor fixation status of the intake and exhaust pipe.

In general, the intake and exhaust pipes installed in a heating device such as a boiler perform a function of discharging exhaust gas generated by combustion in a burner and a function of sucking air required for combustion from the outside.

However, the conventional intake and exhaust pipes are connected to the outer wall of the exhaust gas backflow preventing plate 12 and the first intake pipe 11 at the end of the first exhaust pipe 10 by cutting a pipe having a relatively small diameter. The first intake pipe formed by cutting the pipe having a larger length than the diameter of the first exhaust pipe 10 by a predetermined length of the first intake pipe 13 is provided on the outside of the first exhaust pipe 10 so that the one end portion thereof is provided. 13 is fixed to the first exhaust pipe (10) and the first intake pipe (11) is formed between the intake air (B) through which the outside air can be introduced, a number of engaging holes 140 a certain interval The fastening band 14 of the predetermined length that has been punctured is fixed to the pressure-retaining member 13 through a spring, and has the same outer diameter as the inner diameter of the first exhaust pipe 10 and has a predetermined length of the second exhaust pipe 20. One end is discarded, but the outer peripheral surface of the exhaust pipe connector connected to the flue (30) of the heating device ( 25), one end of the second exhaust pipe 20 is provided with an intake collecting portion 22 of a square with one surface open, and an intake pipe connector 26 is installed on one side thereof, and the intake collecting vessel The second surface of the suction surface 22 is provided with a fixing member 23 for connecting with the second intake pipe 21, and has the same outer diameter as the inner diameter of the first intake pipe 11 and is cut to a certain length. One end of the engine 21 is coupled to the fixing member 23 and at the same time to install a coupling member 24 that is tightly fixed to the inner wall, the inner side of the engaging hole 140 of the fastening band 14 It had the structure which provided the latching ring 27 to fit.

Therefore, the first exhaust pipe 10, the exhaust gas backflow preventing plate 12, the blotter hole 13, the first intake pipe when the intake and exhaust pipes are formed to be coupled to each other by the holes drilled in the wall 50. The first intake and exhaust pipe body composed of the 11 and the fastening band 14 is pushed through the hole at the outside of the wall, and then the second intake pipe 21 is pushed through the hole in the wall at the room. A part of the second intake pipe 21 is fitted into the first intake pipe 11.

In such a state, while pulling the fastening band 14 fixed at one end to the inside of the squeezing hole 13 of the first intake and exhaust pipe body to the indoor side, while pushing the second intake pipe 21 toward the outside from the inside, The second intake pipe 21 is fitted more deeply into the first intake pipe 11.

Subsequently, if the first intake and exhaust pipe body is not pulled inward despite the pulling of the fastening band 14, the squeezing hole 13 of the first intake and exhaust pipe body is in close contact with the outer wall and the second intake pipe 21 is coupled. The member 24 is in close contact with the inner wall and recognized that the entire lengths of the first intake and exhaust pipe bodies and the second intake and exhaust pipe bodies are equal to the width of the wall surface. The hook ring 27 welded and fixed to the inner surface of the second intake pipe 21 is caught by the catching hole of the proper position, and then a part of the fastening band 14 protruding out of the second intake pipe 21 is removed. Cut it off.

Subsequently, when the end portion of the second exhaust pipe 20 is strongly pushed into the second intake pipe 21, a part of the second exhaust pipe 20 is fitted into the first exhaust pipe 10. The fixing member 23 provided in the opening of the intake collecting section 22 is continued until it is in close contact with the coupling member 24 of the second intake pipe 21.

When the fixing member 23 of the intake collecting unit 22 integrally installed in the second exhaust pipe 20 is in close contact with the coupling member 24 of the second intake pipe 21, the fixing member 23 and the coupling member ( 24) is fixed to the wall with a screw or the like, and then the exhaust pipe connector 25 is connected to the flue 30 of the heating device, and the intake pipe connector 26 is connected to the blower blower device 40 of the burner. The installation work of the exhaust pipe is completed.

However, in this configuration, when the two intake and exhaust pipes are coupled to each other, the first intake and exhaust pipes are inserted outdoors through holes formed in the wall, and then the second intake pipe is pushed into the holes in the room, and then the fastening band Since the first intake pipe must be pressed while pulling, the installation work is difficult and time-consuming.

Of course, one person may install the intake and exhaust pipes by pushing the first intake and exhaust pipes from the outside and the other by pushing the second intake pipes from the inside, but this results in unnecessary waste of manpower. Beget.

In addition, after the second intake pipe is coupled to the first intake and exhaust pipe body as described above, the second intake pipe is forcibly coupled to the first exhaust pipe when the second intake pipe is coupled. In many cases, airtightness with the Millier walls was lost.

In addition, the final fastening of the first intake and exhaust pipe bodies and the second intake pipe is made by two fastening bands, wherein the coupling state of the first intake and exhaust pipe bodies and the second intake and exhaust pipe bodies is loose. If only a small impact from the outside, the coupling of the fastening band is released, and as a result, there is a problem (that is, incomplete combustion and inflow of waste gas, etc.) that the coupling state of the intake and exhaust pipe is poor.

It is an object of the present invention to provide an intake and exhaust pipe fixing device for a heating device, which is very simple to install the intake and exhaust pipe and can be completely fixed to a wall or the like.

Another object of the present invention is to provide an intake and exhaust pipe fixing device for a heating device that can completely prevent incomplete combustion and inflow of waste gas due to a fixed state of the intake and exhaust pipe.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention, as shown in Figure 1, the first exhaust pipe 10, the exhaust gas backflow prevention plate 12, the pressure holding port 13, the first intake pipe 11 and the first band consisting of a fastening band 14 Intake and exhaust pipe bodies; A second exhaust pipe 20, an exhaust pipe connector 25, an intake collecting unit 22, an intake pipe connector 26, a fixing member 23, a coupling member 24, and a second intake pipe 21. In the intake and exhaust pipes of the heating device which combines the intake and exhaust pipe bodies with each other to supply the air necessary for combustion of the heating device and exhausts the combustion gas, a part of the free end of the first intake pipe 11 is provided. The spiral 110 is formed, and the second intake pipe 21 coupled thereto forms the spiral 210 over the whole, so that the first and second intake pipes 11 and 21 are disassembled and assembled by screwing. It is characterized by one.

Here, the reference numeral 15 is a sponge which is installed on the inner surface of the pressing member 13 and the fixing member 23 to seal the periphery of the hole of the wall 50 and at the same time to mitigate the external impact, 28 is for sealing It's rubber.

If described with reference to Figure 2 the effect of the device of the present invention configured as described above.

First, the first intake and exhaust pipe body composed of the first exhaust pipe 10, the exhaust gas backflow prevention plate 12, the brace 13, the first intake pipe and the fastening band 14, After pushing through the hole, the second intake pipe 21 is inserted through the hole in the wall indoors, and only the fastening band 14 is slightly indoors without the need to push each other or pull the fastening band 14 strongly as in the prior art. When only the second intake pipe 21 is rotated in the pulled state, the spiral 210 of the second intake pipe 21 is automatically coupled to the spiral 110 of the first intake pipe 11 so as to firstly rotate the first intake pipe 21. The intake and exhaust pipe body itself is pulled to the indoor side.

That is, as in the prior art, two people push the first and second intake and exhaust pipe bodies themselves in and out of the room and the outside, or one person pulls the fastening band 14 in the room in a second state. ), The first intake and exhaust pipe body is inserted into the hole of the wall from the outside, and the inside of the second intake pipe 21 is inserted into the hole and the fastening band 14 is held approximately. When only the intake pipe 21 is rotated, the helix 210 of the second intake pipe 21 formed over the entire portion of the helix 110 of the first intake pipe 11 is formed, so that the The first intake and exhaust pipe bodies and the second intake pipe 11 move to the wall surface side in correspondence with the rotational speed thereof.

As described above, if the inner surface of the coupling member 24 is in close contact with the wall without further rotation while the second intake pipe 21 is rotated, the holding member 13 of the first intake and exhaust pipe body 13 Recognizing that the state is completely in contact with the outer wall of the wall 50, the rotation operation may be stopped.

Thereafter, one end is fixed to the pressure holding member 13 through a spring, and the locking band 14 is pulled into the second intake pipe 21 so as to be drilled at a predetermined position among several locking holes 140. When the engaging ring 27 of the second intake pipe 21 is fitted in the ball, the first intake and exhaust pipe body and the second intake pipe 21 are fixed in double and the bonding force becomes stronger.

At this time, since the fastening band 14 is formed to be relatively long and a part of the fastening band 14 protrudes to the outside of the second intake and exhaust pipe body, the protruding portion of the fastening band is cut off, and then the second into the second intake pipe 21. When the end of the exhaust pipe 20 is strongly pushed, a part of the second exhaust pipe 20 is fitted into the first exhaust pipe 10 of the first suction and exhaust pipe body.

Therefore, the installer is required to install the second exhaust pipe until the fixing member 23 provided at the opening of the intake collecting portion 22 of the second exhaust pipe 20 is brought into close contact with the coupling member 24 of the second intake pipe 21. 20) and then, the fixing member 23 and the coupling member 24 are fixed to the wall with a screw or the like, and then the exhaust pipe connector 25 is connected to the flue 30 of the heating apparatus, and the intake pipe connector ( 26 is connected to the blower blower device 40 of the burner is completed, the installation work of the inlet, exhaust.

In this way, when the two intake and exhaust pipe bodies are combined, one exhaust path A is formed in the interior of the first and second exhaust pipes 10 and 20 to connect with the flue 30 of the burner, and the first and second exhaust pipes are formed. Between the outer circumferential surface of (10, 20) and the inner surfaces of the first and second intake pipes (11, 21), an air intake path (B) which is connected to the blower device 40 of the heating apparatus is formed.

On the other hand, by forming the spiral 210 over the second intake pipe 21, the entire length of the intake and exhaust pipe can be varied within the length range of the second intake pipe 21, which is relatively thick. It is possible to install intake and exhaust pipes on walls or very thin walls.
