Thermostatic electric water heater

Abstract

The invention relates to a thermostatic electric water heater which comprises a shell, an inner container and a magnesium rod assembly arranged in the inner container, wherein a cold water inlet and a hot water inlet on the inner container are respectively connected with a water inlet connecting pipe and a water outlet connecting pipe, and a digital thermostatic valve part is arranged between thewater inlet connecting pipe and the water outlet connecting pipe; the digital thermostatic valve part comprises a thermostatic valve body, a temperature sensing pipe arranged in the thermostatic valve body, a thermostatic valve computer board, a thermostatic valve motor and a swaying block; an output shaft of the thermostatic valve motor is connected with the swaying block, and both ends of the swaying block are respectively arranged in the water inlet connecting pipe and the water outlet connecting pipe; a thermostatic water outlet pipe is arranged on the thermostatic valve body; the left end of the water inlet connecting pipe is connected with a cold water port end of the thermostatic valve body, and the upper end of the water inlet connecting pipe is connected with the cold water inlet; the right end of the water outlet connecting pipe is connected with a hot water port end of the thermostatic valve body, and the upper end of the water outlet connecting pipe is connected with a hotwater outlet. The thermostatic electric water heater saves water and electricity, is easy to operate and can accurately determine the mixing proportion of cold water and hot water so as to ensure that constant thermostatic hot water flows out of the thermostatic water outlet to realize comfortable scouring baths.

Description

technical field [0001] The invention is an electric water heater, in particular a constant temperature electric water heater capable of providing constant temperature hot water, which belongs to the improvement technology of the electric water heater. Background technique [0002] At present, the vast majority of electric water heaters sold in the market cannot provide constant temperature hot water. The water supply method is to manually rotate the water mixing valve left and right to mix the 75°C high-temperature water flowing out of the inner tank with the tap water in the water inlet pipe and adjust it properly before use. Its preset time is long, and due to the constant change of water flow and water pressure during use, the water mixing valve has to be adjusted again to achieve the desired effect. In order to solve this phenomenon of hot and cold water outlet and waste of energy, someone installed a mechanical thermostatic valve at the water inlet and outlet of the ele...

Problems solved by technology

However, the disadvantage of this technical solution is that within the temperature range of 36-50°C, the low-end constant temperature precision is high, and the high-end precision is low, and it requires cumbersome manual adjustment of the temperature knob and flow adjustment knob, and the installation height is limited, let alone installation. Suitable for unfavorable environments such as ceilings, extra walls, and corners
