Electric water heater

The utility model relates to an electric water heater, comprising a shell and an inner container arranged in the shell; a control circuit board is arranged in the cavity between the shell and the inner container, and the control circuit board is provided with an element which can emit heat in working; the electric water heater is characterized in that: the electric water heater further comprises an inlet tube joint made of heat-conducting material, the inner end of the inlet tube joint is connected with a water inlet of the inner container, the outer end of the inlet tube joint penetrates through the shell and is exposed, and the inlet tube joint arranged in the middle part of the inner container and the shell is connected with the element which can emit heat on the control circuit board in a heat-conducting way. Compared with the prior art, when in work, as the temperature of cold water flowing in from the position of the inlet tube joint is low, the element which can emit heat can dissipate the heat generat
