Description
Technical Field
The utility model belongs to the technical field of the electrical heating, concretely relates to water heater.
Background
Most instant water heaters in the current market adopt: 1. the tank body is in threaded connection with the upper cover; 2. the upper tank and the lower tank are welded in the middle after being stretched; the first method has the defects of high cost, easy failure of threaded connection and easy water leakage at the connecting part. The second scheme has the defects that the tank body cannot be stretched too long, so that the volume is limited, and the heating performance cannot be effectively exerted. The thickness of the stretching material is uneven, stretching lines are easy to generate, the service life of a product is influenced, and the poor flatness can influence the welding quality. The novel technology has the advantages that multiple groups of heating pipes can be arranged in the novel technology, the heating performance of the product is improved, the connection part is more reliable and is not easy to leak water through the extrusion of the upper cover and the lower cover and the tank body and then the argon arc welding or laser welding mode. The product cost is reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome not enough among the prior art, provide a water heater.
In order to solve the technical problem, the utility model discloses a solution is:
providing a water heater, which comprises a tank body and a heating pipe; the upper cover and the lower cover are welded at the top end and the bottom end of the tank body, and are provided with flanges which are in interference fit with the tank body; a through hole is arranged on the side wall of the tank body;
the upper cover is provided with a flanging hole, and the cold end of the heating pipe passes through the flanging hole and is fixed.
As an improvement, a water inlet nozzle and a water outlet nozzle are arranged at the through hole of the side wall of the tank body.
As an improvement, the water inlet nozzle and the water outlet nozzle are welded on the tank body through argon arc welding or laser welding.
As an improvement, the heating pipes are one group or a plurality of groups.
Compared with the prior art, the utility model has the technical effects that:
through can realizing built-in multiunit heating pipe, improve product heating performance, through the extrusion of upper and lower lid and jar body then make the junction more reliable through argon arc welding or laser welding's mode, be difficult for leaking. The product cost is reduced.
Drawings
Fig. 1 is a schematic view of the overall structure of the water heater of the present invention.
Reference numerals: 1-heating a tube; 2-covering the upper cover; 3-lower cover; 4, a water inlet nozzle; and 5, a tank body.
Detailed Description
The invention will be further elucidated with reference to the drawings and the detailed description. Modifications of various equivalent forms of the invention, which would occur to persons skilled in the art after reading this disclosure, are intended to be within the scope of the invention as defined by the claims appended hereto.
A water heater comprises a tank body 5; the top and the bottom of the tank body 5 are welded with an upper cover 2 and a lower cover 3, the side wall of the tank body 5 is provided with a through hole, the through hole is welded with a water inlet nozzle 4 and a water outlet nozzle, and the water inlet nozzle 4 and the water outlet nozzle are welded on the tank body 5 through argon arc welding or laser welding. Compared with a threaded connection, the threaded connection saves cost.
One or more groups of heating pipes 1 are arranged in the tank body 5. The heating performance and the heat transfer efficiency of the product are improved, the corrosion resistance and the scale prevention capability are improved, and the service life of the whole machine is prolonged. The upper cover 2 and the lower cover 3 are both provided with flanges, and are in interference fit with the tank body 5. The upper cover 2 is provided with a flanging hole, and the cold end of the heating pipe 1 penetrates through the flanging hole and is fixed.
The utility model discloses a course of working does:
the water inlet and outlet nozzle is welded with the tank body 5, the heating pipe 1 is welded with the upper cover 2, the upper cover 2 and the lower cover 3 are pressed into the tank body 5 to be tightly matched, and then the water inlet and outlet nozzle and the tank body are connected together through argon arc welding or laser welding.
Finally, it is to be noted that the above-mentioned embodiments are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
