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.
