Description

Technical Field

[0001] The utility model relates to an enamel storage tank for a water heater with a reverse buckle head, belonging to the technical field of water heaters. Background Art

[0002] A gas water heater uses gas as fuel and transfers heat to cold water flowing through a heat exchanger by combustion heating to achieve the purpose of preparing hot water, which is a gas appliance.

[0003] When manufacturing an enamel storage tank for a water heater, spray enameling processing needs to be carried out inside it. The storage tank of the water heater is a hollow cylinder with a top cover at its top. Therefore, after opening the top cover, workers carry out spray enameling treatment on the inner wall of the cylinder from above. However, the top cover is far from the bottom of the cylinder, and usually the spray enameling effect on the bottom of the cylinder is not good, which in turn affects the quality of the enamel storage tank for the water heater. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above deficiencies and provide an enamel storage tank for a water heater with a reverse buckle head that can ensure complete spray enameling of the inner wall of the cylinder and improve the spray enameling quality of the storage tank.

[0005] The purpose of the utility model is achieved as follows:

[0006] An enamel storage tank for a water heater with a reverse buckle head includes a cylinder. A top cover that can be opened is provided at the top of the cylinder. One end of the top cover is hinged to the cylinder. A base is provided at the bottom of the cylinder. The base has four feet, and the cylinder is supported by the four feet, with the bottom of the cylinder vacated. A round hole is opened at the center of the bottom of the cylinder. A disc is provided at the round hole. The top of the disc bulges upward, and the bulging surface of the disc is subjected to enamel treatment. The disc completely blocks the round hole. A flange is fixed to the bottom of the disc, and the flange is connected to an external pipeline through a flange.

[0007] The bulging surface of the disc is larger than the aperture of the round hole.

[0008] The bottom of the disc protrudes from the round hole.

[0009] The enamel storage tank for a water heater with a reverse buckle head of the utility model has the following advantages:

[0010] For this enamel storage tank for a water heater with a reverse buckle head, spray enameling is carried out on the inner wall of the upper half of the cylinder from the top cover; by opening a through hole at the bottom of the cylinder, spray enameling is carried out on the inner wall of the lower half of the cylinder from the through hole; and a disc with a pre-surface enamel is welded on the cylinder, so that the inner wall of the cylinder can be conveniently spray-enameled comprehensively, improving the spray enameling quality of the storage tank. Description of the Drawings

[0011] Figure 1The utility model is a structural schematic diagram of an enamel storage tank of a water heater with an inverted head.

[0012] In the figure: cylinder 1, top cover 2, base 3, round hole 4, disc 5, flange 6. DETAILED DESCRIPTION

[0013] See also Figure 1 The utility model relates to an enamel storage tank for a water heater with an inverted cover, comprising a cylinder 1, a top cover 2 which can be opened is arranged on the top of the cylinder 1, one end of the top cover 2 is hinged to the cylinder 1 and can be turned outward. A base 3 is arranged at the bottom of the cylinder 1, and the base 3 has four legs, which support the cylinder 1 through the four legs, and the bottom of the cylinder 1 is vacant.

[0014] A circular hole 4 is provided at the center of the bottom of the cylinder 1, and a worker reaches into the circular hole 4 to spray enamel on the lower half of the inner wall of the cylinder 1. A disc 5 is provided at the circular hole 4, and the top of the disc 5 is convex upward. The convex surface of the disc 5 is enameled, and the convex surface is slightly larger than the aperture of the circular hole 4, so that the disc 5 can completely block the circular hole 4, and the bottom of the disc 5 is exposed from the circular hole 4.

[0015] A flange 6 is fixed to the bottom of the disc 5. When the inner wall of the cylinder 1 is completely enameled, the disc 5 is welded to the cylinder 1, and the flange 6 is connected to the external pipeline through the flange, so that the cylinder 1 can transport water to the pipeline.
