Description

Electric frying pan and heating tube liner

[technical field]

The utility model relates to an electric heating tube heating device, in particular to an electric frying pan and a heating tube liner.

[Background technique]

Traditional gas-heated frying pans need external gas pipelines, so it is very inconvenient to use gas-heated frying pans in places where it is inconvenient to lay pipelines and use electricity.

Electric heating pots sold on the market generally use electric heating tubes for heating. Electric hot pots can be divided into electric rice cookers for cooking and egg steamers for steaming eggs according to their functions.

Rice cookers are bulky and heavy. Electric rice cookers are generally heated by setting electric heating wires at the bottom of the aluminum plate. The aluminum plate is generally thicker, and the electric heating tube heats the aluminum plate. The heating speed is slow, far inferior to the egg steamer, and cannot be used for stir-frying.

The egg steamer is generally small in size, and the electric heating tube is directly welded to the bottom of the stainless steel heating plate, and water is placed in the heating plate, which mainly heats the water to form water vapor to steam the eggs. Although the egg steamer has the characteristics of fast heating, when the electric heating tube directly heats the stainless steel heating plate, the temperature of the bottom of the heating plate rises quickly, and the temperature of the plate wall rises slowly. Cooked phenomenon, can not be used for cooking.
