Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and particularly relates to a double inner tank assembly and an electric water heater thereof. Background Art

[0002] At present, the double inner tank assembly of an electric water heater has two inner tanks, which are welded together through a connecting pipe. The connecting pipe uses a flanging structure, but the flanging is not flat or the position of the butt joint is prone to dislocation, resulting in a high welding defect rate and potential water leakage safety hazards. In addition, with the flanging structure, the distance between the two inner tanks is relatively large, resulting in a relatively high height of the water heater product. Content of the Utility Model

[0003] The purpose of the utility model is to provide a double inner tank assembly and an electric water heater thereof, which can reduce the product height by means of a pressing platform and a welded connecting pipe, so as to overcome the deficiencies of the prior art.

[0004] The technical solution of the utility model is: a double inner tank assembly is applied to an electric water heater. The electric water heater has a first inner tank and a second inner tank. Connecting pipes are respectively connected to the first inner tank and the second inner tank, so that the two inner tanks are connected in communication. The feature is that a pressing platform with a 5 mm depression is arranged on the first inner tank and / or the second inner tank. A platform opening corresponding to the connecting pipe is arranged on the pressing platform, and the end of the connecting pipe is welded on the platform opening.

[0005] Pressing platforms with a 5 mm depression are arranged on the middle cylinders of the first inner tank and the second inner tank. The connecting pipe is first welded on the platform opening of the pressed first inner tank, and then welded on the platform opening of the pressed second inner tank.

[0006] An inlet and outlet water pipe sleeve and a sewage pipe sleeve are arranged on the outer wall of the middle cylinder of the second inner tank far away from the pressing platform.

[0007] Arc transition sections are arranged at both ends of the pressing platform, and the arc transition sections are connected to the left and right end covers of the two inner tanks.

[0008] The number of the connecting pipes is two.

[0009] A water heater includes the above-mentioned double inner tank assembly.

[0010] The utility model has the following beneficial effects: by arranging a profiled platform on the outer walls of the two inner tanks, the connecting pipes of the two inner tanks are welded and formed with the inner tanks on the profiled platform. The connecting pipes meet the requirement of mutual connection between the two inner tanks. Moreover, when the connecting pipe is welded to the first inner tank, the welding torch will extend into the sunken profiled platform, so that there is enough welding operation space, and the distance between the first inner tank and the second inner tank is effectively shortened, thereby finally reducing the overall size of the water heater, effectively reducing the installation space of the whole machine, and providing a better use experience and sensory feeling for users.

[0011] By welding independent connecting pipes on the profiled platform, the flatness of the butt joint of the two inner tanks is ensured, the welding qualification rate is improved, and the risk of water leakage is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
