Detailed Description
The following will describe in detail an embodiment of the electric hot plate output power control platform of the present invention.
The electric cooker should be watched by people when cooking and stewing meat to prevent soup and the like from overflowing into the electric appliance to damage electric appliance elements and not to knock the electric cooker frequently. Because the inner container of the electric cooker is easy to deform after being touched, the bottom of the deformed inner container can not be well matched with the electric heating plate, so that uneven heating is caused during cooking, and raw rice is easy to cook.
When the electric cooker is used, the inner pot can be rotated left and right for several times by paying attention to good contact between the pot bottom and the heating plate, the key switch can automatically bounce after the rice is cooked, the pot is not suitable to be opened immediately at the moment, and the rice can be cooked thoroughly after being stewed for about 10 minutes.
In the cleaning process, the electric appliance part is not contacted with water to prevent short circuit and electric leakage, and before the inner container is cleaned, the inner container can be soaked in water for a while without brushing the inner container with a hard brush. After cleaning, the cleaning cloth is needed to be wiped clean, and the bottom of the cleaning cloth can not be put into the shell with water. The outer shell and the heating plate are forbidden to be soaked, the outer shell and the heating plate can only be wiped clean by wet cloth after the power supply is cut off, after the electric cooker is used, the power supply plug is immediately pulled out, otherwise, the automatic heat preservation still plays a role, the electricity is wasted, and elements are easy to burn out.
The pot body of the electric cooker is made of ceramic, enamel, aluminum alloy, stainless steel and the like. The inner wall of the inner pot is usually sprayed with a polytetrafluoroethylene anti-scorching coating, so that the inner pot is not easy to be burnt during cooking and is easy to clean. If the pan body is made of aluminum alloy, the surface of the pan body is not brushed to be damaged when the pan is cleaned, because the aluminum in the material can enter the rice, the aluminum element can damage brain cells of people after long-term use, thereby affecting the function of the brain cells, causing the memory to be reduced and the thinking ability to be slow.
