Electric shock preventing protector of electric water heater

Abstract

The invention discloses an electric shock preventing protector of an electric water heater, which comprises an upper insulating cover, a lower insulating cover and an insulating trough disc. The upper insulating cover and lower insulating cover are sealed on the upper and lower end surfaces of the insulating trough disc, respectively. A water inlet pipe and a water outlet pipe are formed on the upper insulating cover and lower insulating cover, respectively. A plurality of circles of independent water channel walls in one-to-one correspondence are arranged on both upper and lower end surfaces of the insulating trough disc. A groove type waterflow channel is formed between two adjacent water channel walls. The waterflow channel in the outermost circle of the end surface of the insulating trough disc is communicated with the water outlet of the water inlet pipe in a sealing mode, and the space in the innermost circle of water channel wall on the lower end surface of the insulating trough disc is communicated with the water inlet of the water outlet pipe in the sealing mode. The waterflow flows from the water inlet pipe and flows in the waterflow channel on the upper and lower end surfaces of the insulating trough disc to increase the length of the current so as to realize the function of electric shock prevention. The invention has the advantages of ensuring hermeticity of the waterflow channels effectively with good anticreep function and ensuring life safety of people effectively with stable quality and low manufacturing cost.

Description

technical field [0001] The invention relates to an electric safety device for an electric water heater. Background technique [0002] As an energy source, electricity has the characteristics of cleanness, high efficiency and safety, so electric water heaters are widely used in thousands of households. However, during people's use, due to various reasons, most of the grounding wires are unreliable, and the leakage of electric water heaters has caused hidden dangers to people's life safety. The flow channel increases the resistance value of the water flow to meet the requirements of leakage prevention. At present, the main ways to lengthen the water flow channel are spiral water flow channel, mosquito-repellent incense type water flow channel, etc. However, the above-mentioned water flow channel structure is too large to be conducive to installation. , such as a spiral water flow channel, or a product with a high failure rate and high manufacturing cost, such as a mosquito co...
