AI Technical Summary

Problems solved by technology

But this technical scheme still has its shortcomings: 1, because the insulating tube is set outside, it can be installed when the user installs it, so it is possible to bring many uncertain factors, such as the increase of randomness, and the safety Not easy to guarantee
2. The external setting of the insulating tube is not easy to match with the user tube, and the number of tube joints increases

Embodiment Construction

[0021] see figure 1 , the entire electric water heater is represented by a mark 20 total. In order to overcome the defects of the external insulation tube, and meet the length L of the insulation tube > 53r 2 requirements, so as to ensure that the requirements of safety standards are met. The technical solution of one of the embodiments of the present invention is: the water inlet liner 1 is a combination of a straight pipe and a sleeve 6, and its structure is: a sleeve 6 connects the pipe body of the water inlet liner 1 in the liner 5 Partial cover installation, the two water pipes 1, 6 are fixed by bolts 7 and nuts 11 at the junction of the top surface, the two water pipes 1, 6 can also be integrated, and the water inlet liner 1 has a through hole 16 on the pipe wall near the top , the gap between the two water pipes 1, 6 is a water flow channel 17, the water outlet 18 at the lower end of the casing 6 communicates with the inner tank 5, the water inlet liner and the casing...

Abstract

The electroshock-proofing electric water heater includes shell, internal container, water intake tube, water discharging tube, water discharging lining tube and water intake lining tube. It is characterized by that the described water intake lining tube is an insulating tube, its tube body is placed in the internal container cavity, and adopts the structural forms of inverted U shaped, M-shape or water intake straight tube and casting tube cover assembly, so that it increases zigzag length of water flow line and makes the length L from water inlet of water intake lining tube to water outlet attain the the safe length requirement of that L is greater than 53 sq.r.

Description

technical field [0001] The invention relates to an electric water heater, in particular to the improvement of the structure of the existing electric water heater. Background technique [0002] There are two most commonly used anti-leakage methods for existing electric water heaters. One is to use a leakage switch. When the leakage current exceeds a specified value, the power supply can be automatically cut off to ensure safe and reliable use of the electric heater. The other is to install an automatic leakage detection device on the electric water heater. When the leakage current exceeds the specified index, it will automatically alarm and remind the user to turn off the power supply to ensure the safety of the user. However, the above two protection methods make the user highly dependent on the leakage protection device. In case the leakage switch or the automatic detection alarm is damaged or fails, the leakage will occur, and even threaten the life ...
