Electric water heater with a lining having electric insulating connection with a casing

Abstract

The invention discloses an electric heater, of which internal bladder is insulated with the shell in electricity. The internal bladder covered by insulation material is set in the shell symmetrically. Insulating module is embedded in the mother body of insulating module. The mother body of insulating module enters into the internal bladder from one side of the support for internal bladder and theepitaxial part of the mother body makes the support for internal bladder isolate with the shell in electricity. In-out water ports are isolated with the shell in electricity and electricity-proof isolation wall device is set. The internal bladder of electric heater is isolated with the shell entirely. The leaked current of in-out water path and outer pipe is constrained in a safe range and human safety is ensured absolutely when the internal bladder is electrified and the ground wire is not reliable.

Description

technical field [0001] The invention relates to an insulating component and an electric water heater using the insulating component, in particular to an electric water heater with an insulated shell. Background technique [0002] In the previous invention patent 02114552.0, it is disclosed that a compact anti-shock device is connected to the water inlet and outlet of the electric water heater, and the resistance generated by the water flow through the insulating channel is used to realize the effect of "electricity-proof partition wall". It ensures that even if the ground wire is unreliable, if the water heater leaks electricity, the waterways and pipes other than the water inlet and outlet will not be charged. The personal safety problem in the bathing process is solved. [0003] However, even the electric water heater using this technology is not perfect, and there are still hidden dangers as follows: since the inner tank and outer shell of the water heater are usually ma...

AI Technical Summary

Problems solved by technology

[0003] However, even the electric water heater using this technology is not perfect, and there are still hidden dangers as follows: since the inner tank and outer shell of the water heater are usually made of metal, the inner tank and outer shell of the water heater are all formed in an electrical conduction state through the connecting device, and the metal inner tank and outer shell are all made of metal. Although the shell of the water heater is coated with insulating paint, its electrical insulation performance is not reliable

If a person touches a certain part of the shell of the water heater while taking a bath, it may still cause an electric shock accident and cause harm to the user.
