Do You Know the Main Composition of Electric Cooker?

Electric rice cookers are generally composed of a pot body, electric heating elements, temperature control, and timing devices.

Pot body

There are inner and outer layers or inner, middle, and outer layers. The inner pot body is used to hold the food to be cooked, which is often made of aluminum alloy, enamel, or stainless steel, and its inner surface is coated with polytetrafluoroethylene to prevent food from sticking to the pot; The outer pot body plays the role of safety protection and heat preservation. It is generally made of a thin steel plate, and the surface is painted or enameled. The air interlayer between the inner and outer layers of the pot can also be filled with insulating materials. The three-layer pot body is a medium pot body added between the inner and outer two layers of the pot body to form a steamer and play a double heat preservation role.

Electric heating element

It is usually a metal tube type, which is mostly cast in an aluminum heating plate, and the heat emitted is evenly heated at the bottom of the inner pot through the heating plate. Generally, electric rice cookers are only equipped with one bottom electric heating element. To obtain a better cooking effect, some high-end products are equipped with 2 ~ 4 electric heating elements, which are used as top cover heater and side peripheral heater respectively, and the power can be divided into multiple grades.

Temperature control and timing device

The temperature control device often used on ordinary rice cookers is generally composed of a temperature limiter and a thermostat. The former ensures that the pot temperature will not exceed a certain value (usually 103 ± 2 ℃), and is installed in the cavity in the center of the heating plate; The latter ensures that the food in the pot is stable at 60 ~ 80 ℃ after cooking, and is installed under the heating plate or other appropriate positions. Since the 1980s, timers have been used more and more in electric cookers, mainly clockwork mechanical timers.

Liner

Thickened densified alloy liner; Firm and not easy to deform; Widened shallow bottom capacity design makes cooking faster and cooking more uniform.

Heating plate

The thickness of the special aviation aluminum widened and the thickened heating plate is 120mm, which is thicker than the ordinary heating plate, more resistant to high temperature, and heating is more uniform and fast; has a Longer service life and more guaranteed quality.

Lid

The thickened stainless steel lid and the new handle design are more high-end and beautiful.

Power cord

Scientific and safe line displacement design, using 1.5 mm2 pure copper silicone internal wiring, high-quality temperature controller, and special safety insulation protection at each line joint, which is safe, power-saving, and efficient.
