Description

Technical Field

[0001] The utility model relates to the technical field of electric water faucets, in particular to an electric water faucet with uniform water outlet temperature. Background Art

[0002] Electric water faucets have the advantages of fast and continuous hot water delivery, and are therefore increasingly being used by users. When the water flow through the electric water faucet changes during use, the electric water faucet uses a thyristor (SCR) located within the faucet to adjust the heating power of the electric heating tube within the faucet. Currently, electric water faucets on the market include a housing assembly, an electric heating tube, and a water valve. The water valve is connected to the housing assembly, which includes a water heating chamber within the housing assembly. The heating end of the electric heating tube extends into the water heating chamber, and the water outlet end of the water valve communicates with one end of the water heating chamber. The housing assembly is provided with a water outlet that communicates with the middle of the length of the water heating chamber. However, in the aforementioned electric water faucet structure, because the water outlet communicates with and delivers water from the middle of the length of the water heating chamber, tap water from the water valve may not fully flow through the heating end of the electric heating tube and the water heating chamber, but may be discharged from the water outlet. This affects the heating effect and heating uniformity of the tap water by the electric heating tube, making it difficult to maintain a constant temperature of the water flowing out of the electric water faucet.
