Description
Technical field
The present invention relates to a kind of electric heater technical field, especially a kind of safe electric heater.
Background technology
Currently, existing electric heater, such as kettle or electric heating pot, heating structure are usually in vessel
Bottom outside installs heat-generating pipe, and then bottom case is installed in vessel bottom again, so that heat-generating pipe is not leaked outside, which belongs to traditional
Electric heating device, but if when there is defect in heat-generating pipe manufacturing process or vacant two heat-generating pipe of vessel continue plus
Heat, that is, when being commonly called as dry combustion method, all causing heat-generating pipe to occur at high operating temperatures, burning is molten, and formation high-temp liquid or solid damage fall on modeling
Expect that the bottom case of material, the liquid of high temperature continue to burn deck contact of the bottom case directly with placement electric heater, it is most likely that cause
Fire, there are great security risks.
Invention content
It is an object of the invention to solve above-mentioned the deficiencies in the prior art, and the electric heater of brand new is provided, passed through
Security protection is carried out to heat-generating pipe, after effectivelying prevent heat-generating pipe high temperature burning molten, high-temp liquid or solid damage are fallen on bottom case, effectively
Avoid the generation of safety accident.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of safe electric heater, including vessel, vessel bottom are connected with bottom case, the container sheet in bottom case
