Electric water heater and constant temperature control device thereof

Abstract

The invention relates to a constant temperature control device of an electric water heater. The constant temperature control device comprises a body, a water mixing assembly and a control valve assembly. A cold water casing pipe and a hot water casing pipe are connected in a butt joint manner to form a water mixing cavity. The hot water casing pipe is internally provided with a hot water channel,one end of the hot water channel communicates with a hot water inlet, and the other end of the hot water channel communicates with the water mixing cavity. The cold water casing pipe is internally provided with a cold water channel and a mixed water channel. One end of the cold water channel communicates with a cold water inlet, and the other end of the cold water channel communicates with the water mixing cavity. One end of the mixed water channel communicates with the water mixing cavity, and the other end of the mixed water channel communicates with a mixed water outlet. The control valve assembly comprises a fixing base and a valve element. One end of the valve element stretches into the water mixing cavity and is provided with a first blocking part and a second blocking part. The valve element can move in the axial direction of the body to adjust the flow of hot water flowing into the water mixing cavity from the hot water channel and the flow of cold water flowing into the watermixing cavity from the cold water channel. In this way, by means of the moving of the valve element, the flow of the hot water entering the water mixing cavity and the flow of the cold water enteringthe water mixing cavity can be precisely adjusted, and therefore rapid and stable constant-temperature water flowing out can be achieved, and using is convenient. The invention further provides the electric water heater.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to an electric water heater and a constant temperature control device thereof. Background technique [0002] At present, ordinary water storage electric water heaters use an external mechanical water mixing valve for temperature adjustment. This kind of mechanical water mixing valve needs to be continuously adjusted during use to make the outlet water temperature reach the required temperature. It is very inconvenient to operate and the adjustment accuracy is relatively low. Low, the outlet water temperature is sometimes high and sometimes low, and the constant temperature effect cannot be achieved, which affects the bathing experience. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide an electric water heater and its constant temperature control device, which can effectively improve the operation convenience and...
