Abstract

The utility model relates to the technical field of electric heater inner containers, in particular to a novel water heater capable of preventing dry heating of an inner container. According to the utility model, the water in the inner container can not flow back out from the water inlet pipe of the inner container through the U-shaped pipe after the water level of the inner container is just lower than the air exhaust hole on the U-shaped pipe. And the water outlet angle valve is not installed due to the installation error, and after the water heater is heated for the second time, the inner container generates pressure to press the water in the inner container out of the water outlet. Because the exhaust hole on the U-shaped pipe is exposed out of the water surface, air does not enter the water inlet pipe of the inner container and the inner container, and the water in the inner container can not flow back out, so that the problem of dry burning damage caused by water shortage of the inner container of the water heater can be effectively prevented, and the service life of the inner container of the water heater is prolonged.
