Electric water heater with structure of multiple pipes heating separately

Abstract

The present invention discloses an electric water heater with a structure of multiple pipes heating separately, including an electric water heater body with an inner container, a hot water pipe joint and a cold water pipe joint which are connected with the electric water heater body, a coronal end of the body is provided with one upper electrothermal tube flange and at least one lower electrothermal tube flange. The upper electrothermal tube flange is above the lower electrothermal tube flange, and at least one intermediate electrothermal tube flange is detachably fixed on the upper electrothermal tube flange. At least three electrothermal tubes are distributed vertically at intervals in the inner container, one service end of at least one electrothermal tube is connected with the upper electrothermal tube flange, and the intermediate electrothermal tube flange is connected to the service end of an electrothermal tube, so does the lower electrothermal tube flange. All electrothermal tubes can be bent at will according to requirements. With the present electric water heater, different heating combinations can be provided and transformed according to different demands of hot water, so different layers of water can be accurately heated according to demands, and water can be heated evenly and quickly by separately heating.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a structural improvement of a heating device of the electric water heater. Background technique [0002] Due to the continuous improvement of people's living standards, electric water heaters have become increasingly popular in every family. At present, in order to enhance its regulation function, the existing electric water heaters with adjustable power basically adopt double heating tubes to be adjacently arranged on the same heating tube flange, and all of them are concentrated in the middle and bottom of the inner tank. Such a heating structure has a single adjustment function, and the heated water circulation in the inner tank is slow. The water temperature in the upper part of the inner tank is often lower than that in the middle and bottom, and the water temperature is uneven, which should affect the comfort of the electric water heater. Contents of the invention [0003] In ...
