Water-storing type electricity-proof wall water heater

Abstract

The invention discloses a water-storage water heater with electricity-protection wall technique, which comprises a shell, an inner frame, an insulating inlet water pipe and an insulating outlet water pipe. The shell is provided thereon with a water inlet and a water outlet. The insulating inlet / outlet water pipes are provided inside with an insulating mechanism which allows the length of inlet / outlet water paths inside the pipes to be larger than the actual length of the insulating inlet / outlet water pipes, a screw-like spiral bar in a spiral conveyor is arranged inside each of the insulating inlet water pipe and the insulating outlet water pipe, so as to form a spiral through water path inside the pipe, or a twisted bar twisted from a plastic sheet is used to replace the screw-like spiral bar. The insulation mechanism tallies with the inner holes of the pipes in shape, the water paths inside the pips twist and circulate along the twisted plane of the insulation mechanism and is fixed inside the insulating inlet / outlet water pipes via screws, and the insulating inlet / outlet water pipes, the inner frame and the shell are fixed each other via improved screws. The invention has the advantages of no need of being installed by a user, good hidden effect, no increase in occupied space, and good electricity-protection effect; and solves the problems of inconvenient use and potential electric shock caused by the improper installation when the user installs the water heater by himself.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a water storage type electric water heater, in particular to a safe and anti-electricity storage type electric wall water heater. Background technique [0002] There are two main methods of leakage prevention most commonly used in existing electric water heaters: one is to use a leakage switch, and when the leakage current exceeds the specified value, the power supply can be automatically cut off to ensure the safety and reliability of the electric heater; An automatic leakage detection device is installed 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 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 leakag...

[0009] However, the above-mentioned water inlet and outlet pipes L>53r 2 The structure of the anti-electricity principle is a way to increase the length of the water inlet and outlet pipes. Whether it is bent inside the inner tank or placed between the outer shell and the inner tank, it will occupy a certain amount of space, and the bending structure set in the inner tank its installation is inconvenient
