The present invention relates to a hot water heating policy using a small electric boiler, more specifically, hot water heating using a small electric boiler to insert a hot water pipe into the mattress of the bed and circulate the hot water inside the hot water pipe through the electric boiler and the like. It's about the bed.

Recently, as the general public has focused on health, a lot of attention has been focused on bed life with a heating system, which is a bedtime culture that requires a comfortable rest after a day's work.

First, a bed with a built-in conventional heating device most commonly used is to install a plurality of springs of an elastic body inside the upper surface of a constant mold to use a mat wrapped in a fiber material, such a heating device The bed with the built-in bed has the effect of excellent cushioning effect by the spring installed inside the mat, but the problem of the abnormality in the body due to the buffering action is reduced due to long use, that is, the disc or the spine bones, etc. There was an unsuitable problem for older adults who grew up in the ondol room since they were not equipped with heating.

In the related art hot water mat, 'hot water circulation mat' (Korean Registered Utility Model Publication No. 20-0360229) has been devised to minimize the discomfort of the body contact area caused by the exposure of the circulation pipe.

In addition, Korea Registered Utility Model Publication No. 20-0378289), which allows the user to feel the cushion of a comfortable bed, was created.

The hot water mat as described above has a loop-shaped insertion groove formed on the upper surface of the cushioning material, and a circulation pipe is installed in the insertion groove.

By the way, when the mat is folded, the elastic force of the circulation pipe and the cushioning material made of synthetic resin is different, so that the force of the circulation pipe from the insertion groove increases.

Therefore, repeating the operation of folding and mating the mat for a long time causes a problem that the circulation tube is separated from the insertion groove.

In order to solve this problem, it is possible to prepare a wire mesh in the form of a net and twist the circulation pipe to the wire mesh or install the circulation pipe in other structures, and fix it by tying it with a string. However, the circulation pipe is not completely fixed and the hot water mat is folded. Problems occur when the circulation tube breaks out when unfolded.

In addition, since the circulation pipe is seated on the cushioning material, when the performance of the cushioning material decreases according to a long time of use, in particular, when the cushioning material such as a sponge is used for a long time, the cushioning feeling is reduced. There was a problem that gives the user a discomfort.

In addition, in order to solve the above problems, a plurality of layers of cover sheets or cushioning materials may be installed on the hot water mat, but there is a problem in that the heat transfer to the user's skin is blocked to halve the electric boiler use efficiency and thermal efficiency.

In particular, when the mat is repeatedly folded or unfolded, load is concentrated on one side of the cushioning material, which reduces the cushioning feeling. Particularly, at this load concentration point, the circulation tube protrudes from other parts, and thus the user contact part. There was also a problem to stimulate.

In addition, when the cushion material is used for a long time, there is a problem in that both the circulation pipe and the cushion material have to be discarded.

On the other hand, as a technology related to such a small electric boiler used in such a hot water mat, a boiler of a hot water mat having an assembled submersible motor case (Korean Registered Utility Model Publication No. 20-0360548) was devised.

In addition, a 'hot water circulation pump having a hot water heating means and a hot water mat structure using the hot water circulation pump' (Korean Patent Publication No. 10-2005-0120844) has been devised.

However, the small electric boiler as described above has a problem in that the housing in which the water is heated is sealed so that the internal pressure of the housing increases due to the heating of the water.

In order to solve this problem, recently, a small air hole was formed in the upper part of the housing of the electric boiler of the hot water mat, so that the expanded water and air escaped to prevent the pressure rise.

However, since the hot water mat or the like is usually used to be portable or foldable, water inside the housing flows out through the air hole.

As such, the water leaking out from the inside is not particularly suitable for portable hot water mats that repeat folding and unfolding operations.

In addition, the structure in which water flows out may induce short circuits, and if the heated water leaks, a burn accident may occur, causing a lot of safety problems.

An object of the present invention is to solve the above problems, even if the pressure inside the water tank chamber is expanded by the heating of the heating element by using a pressure control device of a small electric boiler, the pressure control device to expand the water and air The present invention provides a hot water heating system using a small electric boiler that can be accommodated to prevent the case from being damaged by the expansion pressure.

Another object of the present invention is that the entire mat is installed with a plurality of cushion members are separated, so even if the mat is folded or unfolded, the load is not concentrated on one side of the cushion member does not occur to extend the life of the cushion member It is to provide a hot water heating policy using a small electric boiler so that the user's skin does not irritate the hot water pipe.

Another object of the present invention is the hot water heating using a small electric boiler so that the connection part is concisely arranged in the connection of the hot water mat and the small electric boiler so that the appearance is good and the convenience can be greatly increased even in the actual assembly or installation. To provide a bed.
