Description

Double communication structure for stove {A DUAL STRUCTURE OF STOVEPIPE}

The present invention relates to a double communication structure for a stove, and in particular, to prevent burns, the communication of the stove such as a firewood boiler is a double structure, and the second communication part is separated from the first communication part connected to the stove by a heat insulating material. It relates to a double communication structure for a stove with an improved structure to minimize heat conduction.

Generally, a chimney is provided for exhausting the stove, and this chimney is connected to the upper part of the stove and has an extended structure. The chimney is a heat and stove that is radiated as smoke generated when burning fuel such as wood or pellets in the stove passes. Since it becomes very hot by the heat transmitted from There was a problem that a fire was caused by the heat conducted from the stove, or the wall contact part was deformed or damaged due to overheating.

In contrast, to prevent burns, a safety net made of a metal material with low thermal conductivity is installed on the outer circumferential surface of the flue installed in the firewood and pellet stove disclosed in Korean Patent Registration No. 10-1134044 (registration date March 30, 2012). that has been proposed

As another example, in Korean Utility Model Publication No. 20-2010-0012357 (published on December 14, 2010), there is a communication cover that forms a cylindrical communication receiving space by attaching two bodies of a hollow semi-cylindrical structure to each other. Disclosed, there is a certain interval between the communication cover and the communication, so that the heat of the communication is not directly transferred to the tent is proposed.

However, since the conventional communication cover or safety net is separately manufactured and installed in the communication tube, there is a problem in that the manufacturing cost and the assembly operation cost are increased.

In addition, in the prior art, as schematically shown in FIG. 1 , a communication 3 having a double structure is formed at the outlet 2 of the firewood boiler 1 , but between the inner communication part 4 and the outer communication part 5 . The space 6 is filled with Cerakwool, a fire-resisting insulation material of very high temperature, to prevent burns even when the user comes into contact with an external chimney. Although the effect is excellent, since it is very expensive, when such ceramic wool is used over a length that a user can contact, there is a problem in that the cost of installing a chimney for preventing burns is greatly increased.

Korean Patent Registration No. 10-1134044 (Registration Date March 30, 2012) Korean Public Utility Model Publication No. 20-2010-0012357 (published on December 14, 2010)

An object of the present invention is to minimize the heat transfer by disposing a second communication part separately with respect to the first communication part connected to the outlet of the stove in order to solve the problems caused by the safety net and the communication cover of the prior art, and by arranging an insulating material therebetween. An object of the present invention is to provide an improved double communication structure for a stove so that a communication pipe capable of effectively preventing burns is installed at a low cost.

In order to achieve the above object, a double communication structure for a stove according to the present invention has a double communication structure for a stove having a first communication part coupled to an outlet of the stove, and a second communication part coupled to an upper end of the first communication part. in the structure,

A connection support portion coupled to the upper end of the first communication portion, an inner end of the connection support portion in close contact with the outer circumferential surface of the second communication portion so as to seal the open upper end of the annular insulating material and the connection support portion disposed inside the upper inner side of the connection support portion It includes a silicone cap disposed on the open upper end,

The connection support part is formed in a cylindrical shape so that the lower part is coupled by inserting the upper end of the first communication part, and the upper part is formed in a cylindrical shape with an enlarged diameter with respect to the lower part,

The second communication part is configured to be spaced apart from the first communication part on the inside of the insulating material in the connection support part.

The connection support portion has a relatively enlarged diameter with respect to the lower portion, and the bottom of the upper portion is formed in a stepped shape, and the annular insulation material is disposed on the outside of the second communication portion and concentrically on the floor from the inner side of the upper portion.

In addition, it is preferable that the second communication part is placed on the step formed inside the annular heat insulating material.

The double communication structure for the stove according to the present invention has a structure in which the second communication part is spaced apart from the first communication part directly connected to the outlet of the stove under the placement of the insulating material. As the first communication part and the second communication part are separated from each other so that the heat transferred from the stove to the first communication part cannot be transmitted to the second communication part that the user can contact, the second communication part may cause burns to the user. It does not rise to a high temperature to the extent that it does not cause burns to the user, thereby improving safety.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing an embodiment of the double communication structure for a stove of the present invention.

In FIG. 2 , the double communication structure for a stove according to the present invention includes a first communication part 10 coupled to the outlet 2 of the stove 1 , and a connection support part coupled to the upper end of the first communication part 10 . (20), an annular heat insulator 30 disposed inside the upper portion of the connection support 20, and a second communication portion 40 disposed inside the heat insulator 30 in the connection support 20.

The double communication structure according to the present invention can be used for communication of various stoves such as a wood boiler, a briquette stove, a pellet stove, or a petroleum stove.

The connecting support part 20 is formed in a cylindrical shape so that the lower part 21 is coupled by inserting the upper end of the first communication part 10, and the upper part 22 is formed in a cylindrical shape with an enlarged diameter with respect to the lower part.

After coupling the first communication part 10 to the outside of the outlet 2 , the connection support part 20 is coupled to the upper end of the first communication part 10 .

The connection support part 20 has a relatively enlarged diameter with respect to the lower part 21 so that the bottom 23 of the upper part 22 has a stepped shape, and the second communication part ( 40) and the annular heat insulating material 30 is disposed on the outside concentrically.

The second communication part 40 is arranged concentrically inside the annular heat insulating material 30 and spaced apart from the inner bottom of the connection support part 20, preferably the second communication part 40 is to be supported on the step 31 formed inside the annular insulating material 30 .

The open upper end of the connection support 20 is formed in an annular shape such that the insulating material cap 25, for example, the second communication unit 40 is inserted, and the inner end is disposed in close contact with the outer circumferential surface of the second communication unit 40. It is sealed with a silicone cap (25). The silicone cap 25 is formed of silicone, or the open upper end of the connecting support part 20 is in close contact with the second communication part on the heat insulating material in a state where the second communication part 40 is disposed inside the heat insulating material 30 . It will be easily understood that it may be formed by applying silicone to seal it.

As a result, the second communication part 40 is spaced apart from the bottom of the connection support part 20 and is supported by resting on a step inside the annular insulating material 30, so that the heat transferred from the stove to the first communication part 10 is first Since the second communication unit 40 is not directly transmitted to the communication unit 40 and is blocked by the heat insulating material 30, the second communication unit 40 is not overheated by the heat of the stove.

The annular insulating material 30 is a high-temperature fire-resistant insulating material having a stable and excellent quality even at an ultra-high temperature of 1,000 ° C or more and having a low thermal conductivity even at a high temperature, and in particular, Cerakwool is preferable.

High-temperature fire-resisting insulation materials such as the above-mentioned Cerakwool are generally expensive, so when a lot of such fire-resistance insulation materials are used, the cost burden is greatly increased. The part 40 is spaced apart from the first communication part 10 and is disposed on the step 31 inside the annular heat insulating material 30, and the outside of the second communication part 40 is insulated by the heat insulating material 30 to form a stove. As the direct heat transfer from Therefore, since an insulating material such as expensive ceramic wool is used only in the upper part of the connection support part 20, the use of the insulating material can be minimized, greatly reducing the cost burden, and the second communication part does not rise to a high temperature, resulting in burns of the user. effectively prevented.

The double communication structure of the present invention can be used to prevent burns in the communication of various stoves, such as a firewood boiler, a briquette stove, a pellet stove, or a petroleum stove.
