Description

Technical Field

[0002] The electric heating handmade pancake machine mainly uses electric heating to make pasta on the griddle surface. It mainly includes the griddle and the heating device at the bottom of the griddle.

[0003] At present, heating devices mainly include gas heating and electric heating. Due to the high cost of gas, electric heating is used except for some places where it is inconvenient to access the power supply. The electric heating device mainly includes electric heating wire or electric heating tube, which is spirally set at the bottom of the griddle. This method will cause uneven heating. There are partitions and electrical components under the electric heating wire or electric heating tube. The partition is generally made of metal plate, which cannot effectively insulate, resulting in poor insulation effect and excessively high bottom temperature.

[0004] Application No.: 201820215968X, discloses an electric pancake machine, including an electric control body, a baking tray, a heating tube and a heating tube fixing piece; an electric control operation cavity is opened in the electric control body, the heating tube and the heating tube fixing piece are located in the electric control operation cavity, and the electric control body supplies power to and controls the heating tube; the upper end surface of the heating tube is attached to the lower end surface of the baking tray; the heating tube fixing piece is provided with a fixing groove, and the heating tube is arranged in the fixing groove, and the heating tube is fixed to the lower end surface of the baking tray by combining a plurality of fixing protrusions on the heating tube fixing piece with a plurality of grooves provided on the lower end surface of the baking tray, so that the heating tube is attached to the baking tray, and there is no gap between the heating tube and the baking tray, and the energy of the heating tube is transmitted to the baking tray as much as possible, so that in the process of making pancakes or thin pancakes, the batter is heated quickly, and the batter is formed into pancakes or thin pancakes in a short time, and the production process is also simple.

[0005] Although the above method heats faster, the heating is uneven. The temperature at the place where the heating tube is directly attached is higher, while the temperature at the gap is lower. The pancakes are also heated unevenly, and the bottom of the heating tube dissipates a lot of heat, causing energy waste. At the same time, it has certain high temperature hazards to the bottom components. Utility Model Content
