Electric water heater

Abstract

The embodiment of the invention provides an electric water heater which comprises at least one liner, at least one connecting part, a connecting pipeline and at least one heating part connected to theconnecting pipeline, wherein each connecting part comprises a fixing part and a buffering part connected to each other, a via hole is formed between the fixing part and the buffering part, and the fixing part is in contact connection to the outer wall of the liner; each heating part penetrating the via hole is arranged at the bottom of the liner and communicates to the bottom of the liner; the connecting pipeline is connected to the liner, so that a fluid enters the liner from the connecting pipeline through the heating part, and flows into the heating part from the liner to be heated duringuse. The electric water heater disclosed by the invention carries out heating by using a thick film heater, so that the heating speed is high, the energy consumption can be reduced and the energy-saving effect is good. Water in the liner can flow, so that the water temperature is uniform. Meanwhile, electric leakage of the thick film heater in water is avoided, so that the safety is high. In addition, the thick film heater is provided with 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, among which electric water heaters are one of them. [0003] A traditional electric water heater includes a sealed container, commonly known as an inner tank, 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. [0004] The heating method using the traditional electric water heater has slow heating speed and low efficiency. After heating, the water temperature is easily affected by the outside world, the heat preservation ability is poor, and the heating of the electric heating tube is not safe. If th...

[0004] The heating method using the traditional electric water heater has slow heating speed and low efficiency. After heating, the water temperature is easily affected by the outside world, 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 hazard. risk

Another heating method is to install the heating device outside the inner tank to heat the water in the inner tank through the outer wall of the inner tank. The heating efficiency is also low, the water in the inner tank is heated unevenly, and the temperature difference is large. The device is prone to noise, which affects the user's use
