As shown in fig. 1-3, the electric water heater of this embodiment includes a water inlet pipe 1 and a water outlet pipe 2, and further includes an electric heating assembly 3, where the electric heating assembly 3 includes a heat conducting coil 31 and an electric heating element 32, the electric heating element 32 is in heat conducting connection with the heat conducting coil 31, and the heat conducting coil 31 is connected with the water inlet pipe 1 and the water outlet pipe 2 respectively.

Specifically, in the electric water heater of the present embodiment, the water inlet pipe 1 is connected to a water supply pipe in a user's home, and the water outlet pipe 2 is connected to a hot water output member such as a hot water cold head or a shower. In actual use, the inlet pipe 1 delivers the introduced cold water to the heat conductive coil 31, and at this time, the electric heating part 32 is energized to heat and release heat and conduct the heat conductive coil 31. The total flow path length of the water flowing through the heat conductive coil 31 is long, so that the water is gradually heated to form hot water during the flowing in the heat conductive coil 31 and is output from the outlet pipe 2. And because electric heating element 32 is located the outside of heat conduction coil 31, electric heating element 32 can not with water direct contact at the in-process of ohmic heating, like this, alright form the incrustation scale in electric heating element 32's surface with avoiding the incrustation scale to electric heating element 32 causes the corruption.

The temperature control mode of the temperature controller 5 may be a conventional temperature control mode, which is not limited and described herein.

Wherein, in order to improve the heat conduction efficiency, the heat conduction coil 31 is coiled around the electric heating part 32. Specifically, the heat conducting coil 31 is installed outside the electric heating element 32 in a spiral winding manner, so that a larger heat conducting area can be formed between the heat conducting coil 31 and the electric heating element 32, and the electric heating element 32 can heat the heat conducting coil 31 more efficiently.

Further, for better heat conduction, a heat conductive adhesive may be disposed between the heat conductive coil 31 and the electric heating part 32. Preferably, the electric heating assembly 3 comprises a protective casing 33 in which the heat conducting coil 31 and the electric heating element 32 are located, the two ends of the heat conducting coil 31 hermetically protruding outside the protective casing 33.
