This is to prevent the closed end of the hot water being difficult to use as the temperature of the entire hot water falls to a temperature lower than the set temperature while meeting each other in the supply pipe 80 . That is, as the flame of the combustion chamber is relatively weak during the initial operation of the household boiler, the heat of the exhaust gas is relatively low, and the temperature of the direct water heated by the heat recovery pipe 140 is significantly lower than the set temperature of the hot water, making it difficult to use hot water.

It is seated while maintaining a bent state in a certain shape. The ID plate 901 that is elastically bent in this way can be stably fixed in the grip part 905 due to the elastic restoring force to return to its original shape. It is possible to reduce the volume when stored or transported in this state, and it is possible to reduce the risk of losing the identity plate 901 .

In FIG. 7 , a handle 901a is formed at the other end of the ID plate 901 , so that when the handle 901a is pulled and pulled, the ID plate 901 exits from the grip part 905 and the relay It is gradually restored to its original shape in the part 904 and is completely restored to its original shape in the insert hole 903 .

And, as shown in FIG. 6, the left and right widths of the insert hole 903 are formed to be slightly smaller than the left and right widths of the identity P plate 901 having the original shape, so that the identity from the insert hole 903 is It is preferable to implement so that the plate 901 does not easily fall out.

In the above description of the present invention, with reference to the accompanying drawings, the "tubular joint type boiler using an identification type coupler" having a specific shape and structure has been mainly described, but the present invention is capable of various modifications and changes by those skilled in the art, such Modifications and variations should be construed as falling within the protection scope of the present invention.
