Description

Integral enamel insulation water tank and water heater

technical field

The utility model relates to hot water equipment, in particular to an integral enamel heat preservation water tank and a water heater.

Background technique

The water heater is a household appliance commonly used in people's daily life, and the water tank is an important component of the water heater. The liner of the water tank is usually welded by the upper and lower heads and the middle barrel, and a heating tube needs to be installed in the liner for heating. In order to improve the water tank and corrosion resistance, usually, the upper and lower heads and the middle barrel are enamelled separately, and then these parts are reassembled and welded together. However, the enamel layer at the weld is damaged by heat. During the process, the weld seam of the inner tank is easily corroded and causes water leakage. How to design a water tank with strong corrosion resistance to improve the reliability of the water heater is a technical problem to be solved by the utility model.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1-2, the integral enamel heat preservation water tank of this embodiment includes an inner tank 1 and a heating pipe 2. The inner tank 1 includes a middle barrel 11 and two butterfly heads 12. The butterfly seals The edge of the head 12 is formed with an inner flange structure 121, and the edge of the inner flange structure 121 is formed with an outwardly protruding guide ring 122, and the guide ring 122 is inserted in the middle barrel 11, and the butterfly head 12 is fixed on the middle barrel 11; the heating tube 2 is fixed on one of the butterfly heads 12 and is located in the inner tank 1, the inner surface of the inner tank 1 and the heating tube 2 The outer surface forms the enamel layer 3 of integral structure.

Specifically, the inner tank 1 and the heating tube 2 of the integral enamel heat preservation water tank in this embodiment form an enamel layer 3 with an integral structure, and the enamel layer 3 will evenly cover the inner wall of the inner tank 1 and the outer surface of the heating tube 2 At the same time, the enamel layer 3 will also cover the connection between the middle barrel 11 and the butterfly head 12 and the connection between the heating tube 2 and the butterfly head 12, effectively avoiding corrosion and water leakage of the liner 1 at the connection position Occurrence, improve the quality of enamel, can reduce the hidden danger of water leakage. At the same time, the butterfly head 12 is flipped 45 degrees inwardly to form an inner flanging structure 121, and then protrudes outwardly to form a guide ring 122. In the process of assembling the liner 1, the operator can conveniently and quickly place the guide ring 12 is inserted into the middle barrel 11 to form a team, and then the butterfly head 12 is fixed on the middle barrel 11, which effectively shortens the time consumed by the workers to form a team liner 1, thereby reducing the assembly and manufacturing costs, effectively Improve the assembly accuracy of the liner 1 to more effectively improve the quality of the enamel. Preferably, the edge of the guide ring 122 is rounded and chamfered to ensure that the enamel layer 3 can be uniformly formed between the inner wall of the middle barrel 11 and the guide ring 122 during the enameling process, so as to further improve the quality of the enamel.
