Material required: screwdriver.
1, first loosen the screw at the bottom of the kettle handle with a screwdriver.
After loosening the screws at the bottom, loosen the screws at the side clockwise.
3. There is a screw at the joint between the handle and the cover, which needs to be loosened.
4. After that, you can remove the handle cover and see the temperature control switch.
5. Tighten the screw on the temperature control switch with a screwdriver to fix the temperature control switch.
6. If maintenance is needed, you can directly replace the temperature control switch.
The working principle of the health pot kettle is that the steam generated when the water boils deforms the bimetal of the steam temperature sensing element and drives the power switch to cut off through the lever principle. Its power failure can't reset itself, so the kettle won't automatically reheat after power failure.
There is something wrong with the health pot, which may be that the heating wire is broken at high temperature. The diameter and thickness of the heating wire are parameters related to the maximum operating temperature. The larger the diameter of the heating wire, the easier it is to overcome the deformation problem at high temperature and prolong its service life. When the heating wire works at a temperature lower than the maximum operating temperature, its diameter should be kept not less than 3mm, and the thickness of the flat strip should be not less than 2mm. ..
The service life of the heating wire is also related to the diameter and thickness of the heating wire to a great extent. When the heating wire is used in high temperature environment, a protective oxide film will be formed on the surface. After the oxide film exists for a period of time, it will age again, forming a cycle process of continuous generation and destruction, which is also a process of continuous consumption of elements inside the heating wire. The heating wire with larger diameter and thickness has more components and longer service life.
