Description

The electric boiler of using the midnight electricity}

The present invention relates to an electric boiler using a late-night electricity that can be used as a low-cost electricity to be supplied to the midnight cheaply to heat the boiler to heat the room or use it as hot water. It is formed by a large number of small-sized tanks that are easy to transport and hand, so that they can be easily disassembled and assembled on site, reducing the overall weight and facilitating manufacturing, reducing costs, and making transportation and installation convenient. It relates to an electric boiler using.

There are many proposals for electric boilers that use low-cost electricity at midnight. For example, in the case of the most common electric boilers in the art, this is a tank that can generally store a certain amount of water inside the main body. At the same time, the electric heater 2 for heating the water stored therein is provided.

In addition, on one side of the main body is provided with a hot water supply pipe (3) for supplying the hot water heated in the water tank (1) to the heating pipe and at the same time to return the heated water heat exchanged through the heating pipe back into the water tank (1). Each return pipe 4 is provided.

Therefore, the electric heater 2 is operated by the cheaply supplied electricity of the late night, and thus the heating water in the water tank 1 is heated to the required temperature and is regenerated, and the hot water supply pipe 3 is selected by the user. Is supplied to the heating pipe of the room through the heat pipe through the heat exchanger in the room to achieve heat, and the heated water is heated through the return pipe (4) into the tank (1) It was to repeat the return.

However, such a conventional electric boiler did not sufficiently obtain the expected effects due to its structural problems, and in order to solve such structural problems, the present applicant has developed an improved electric boiler and applied for a patent registration application. He was elected as 49636.

This improves the hot water supply means for supplying the hot water heated by the electric boiler to the heating pipe side to improve the performance, reduce the manufacturing cost and improve the productivity, and also to maintain the overall strength of the water tank. In order to improve the performance of the electric boiler, the supporting rods, which are installed in a plurality of left, right and front and right directions, can be fixed more stably.

However, in such a prior invention, even if the expected effect can be sufficiently obtained, in order to maintain the strength of the tank, a plurality of supporting rods must be provided inevitably in the up, down, left, right, and forward directions, thereby Problems such as this were caused.

That is, by connecting a plurality of support rods in various directions inside the tank made of a box shape, the workability is not good, and the number of parts also increases, such that the manufacturing cost increases, and these support rods cross the inside of the tank. There is a problem that the contents of the tank is also relatively reduced as it is provided.

In addition, the characteristics of the electric boiler as described above was to store a sufficient amount of hot water required by low-cost electricity at midnight to be stored for a long time, so that the capacity of the tank should be relatively large compared to other boilers, accordingly Since the volume and weight of the entire outgoing, there is a difficult and difficult problem of handling according to the manufacturing and transportation and installation.

In particular, the overall size of the tank, as well as the support rods provided therein, there was a problem such as the increase in weight and the workability significantly reduced when the installation in a narrow space.

The present invention has been made to solve the conventional problems as described above, the purpose is to reduce the volume and capacity of the water tank in the electric boiler using a midnight electricity, while improving the manufacturability and productivity while easily carrying and installation according to It is to provide an electric boiler using a midnight electricity to improve the workability.

The present invention for achieving this object is achieved by improving the structure of the tank, that is, the tank of the electric boiler consisting of a small capacity tank of a size that is easy to transport and install, these small capacity tanks through the flange of the connector It is characterized by improving the manufacturability and installability by minimizing the volume and weight by configuring the mutual assembly and disassembly.
