Assembling structure of fast-heating electric water heating device

Abstract

The invention relates to an assembling structure of a fast-heating electric water heating device. The assembling structure is composed of an electric heating pipe 1, a heating drum 2, a flange 3, a water inlet / outlet cavity 4, an upper cover 5, a sealing ring 6 and a water inlet pipe 7. The electric heating pipe 1 is arranged inside the heating drum 2, the upper end of the electric heating pipe 1 is closely matched with an inner wall of the heating drum 2, holes for installing the electric heating pipe 1 and the water inlet pipe 7 are arranged on the flange 3, the flange is sleeved into the bottom of the heating drum 2, the water inlet / outlet cavity 4 is arranged at the upper end of the heating drum 2, and the sealing ring 6 is arranged between the heating drum 2 and a hole 8 of a water outlet cavity of the water inlet / outlet cavity 4. The assembling structure is compact in structure and good in processibility and can be manufactured with the lowest cost.

Description

technical field [0001] The invention relates to an assembly structure of a fast-heating electric heating water boiling device of an instant electric kettle. The assembly structure can realize that the fast-heating electric heating water boiling device has good manufacturing processability. Background technique [0002] After many years of development, people have developed a variety of electric heating boiling water devices that can continuously provide boiling water, such as a technology that was called "Instant Boiling Water Dispenser" and the authorized announcement number was CN2368420Y in the Chinese patent literature on March 15, 2000. The patent proposes a housing body, the upper part of the housing body is a water tank, and there are multiple outlets at the bottom of the water tank. There are multiple hot water conduits in the water tank. The lower ends of the hot water conduits protrude from the bottom of the water tank. The hot water funnel plate is connected, the ...

AI Technical Summary

Problems solved by technology

The structural features of this patent make the heater only heat a small amount of water in the heater, and send out the water in time after it is boiled, and only after the water is boiled can it be sent out. But the defect of this device is that all the water in the heater needs to be boiled before the water can be discharged, the water discharge speed is slow, and the cold water will inevitably be brought out from the hot water pipe part during use, and the structure is relatively complex

On May 25, 2005, a patent titled "Quick Electric Heating Water Dispenser" with publication number CN1618380A was disclosed. Body, liquefaction tank and additional electric heating body and other components. The electric heating body is formed by the water pipe and the electric heating pipe through the casting body. The electric heating body heats the water flowing through the water pipe and then flows out, so the outlet water temperature is low. Unable to guarantee continuous boiled water

In summary, there are at least the following problems in the above technologies: 1. The heating device is composed of multiple parts, the structure is complex, and the corresponding manufacturing cost is high; 2. The heating device realizes rapid water discharge after power-on, but the water discharge speed is slow and the temperature of the water discharge is not enough. High (75-90°C), even unboiled raw water or mixed raw water; 3. There is a residual cold water in the water outlet pipe of the water outlet of the heating device, and the cold water must be brought out when the hot water is discharged; 4. External heating structure, large size, low thermal efficiency
