Electric water heater

Abstract

The embodiment of the invention provides an electric water heater. The electric water heater comprises at least one inner tank, a water inlet pipe, a heating part and a water outlet pipe, wherein thewater inlet pipe is connected with the bottom of the inner tank to allow fluid to pass through the water inlet pipe into the inner tank, the heating part is connected with the inner tank for the firstheating of the fluid entering the inner tank, the water outlet pipe is connected with the bottom of the inner tank and penetrates through the bottom of the inner tank into the inner tank to dischargethe fluid in the inner tank through the water outlet pipe, wherein the outer wall of the water outlet pipe is coated with a thick film heating casing pipe for the second heating of the fluid discharged from the inner tank. Through the embodiment of the electric water heater, the long supply of hot water of the electric water heater is realized, the heating speed is fast, the energy consumption can be reduced, the energy saving effect is good, and water can flow in the inner tank to make the water temperature uniform; and at the same time, a thick film heater does not leak electricity in water, the safety is high, and in addition, the thick film heater is provided with an overheating protection device to prevent dry burning.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electric water heater. Background technique [0002] With the development of the economy and the popularization of education, people's requirements for furniture have gradually changed, and they have begun to pursue efficient and environmentally friendly furniture. Electric water heaters are also one of them. Traditional electric water heaters include sealed containers, commonly known as liners. And an electric heating tube arranged in the container. When in use, the electric heating tube is required to heat the water in the inner tank before use. [0003] Due to the small volume of the inner tank of the traditional electric water heater, the heating method of the traditional electric water heater cannot meet the user's demand for hot water for a long time after heating, and the heating speed of the traditional electric water heater is slow and the efficiency is ...

Problems solved by technology

[0003] Due to the small volume of the inner tank of the traditional electric water heater, the heating method of the traditional electric water heater cannot meet the user's demand for hot water for a long time after heating, and the heating speed of the traditional electric water heater is slow and the efficiency is low. Low, the water temperature is easily affected by the outside after heating, the heat preservation ability is poor, and the heating of the electric heating tube is not safe. If the electric heating tube is damaged, it is easy to leak electricity, leaving a serious safety risk
