Rice cooker cooking

There are two stages; In full-load stage (boiling water for cooking) and low-load stage (keeping warm, stewing rice and collecting water vapor), the power consumption in low-load stage is generally only110 of full load.

In the full load stage, the average working time is about 20 minutes, and in the low load stage, it is about 10 minutes. Taking the power of the rice cooker as an example, the power consumption is:

2kw * (20/60 hours)+(2 *110) kw * (10/60 hours) = 0.7kwh = 0.7 kwh, so it will cost about 0.35 yuan.

Cooking with natural gas: turn on the gas stove and use about 0.6 cubic meters of gas per hour; Cooking takes about 30 minutes, and natural gas costs about 2 yuan a cubic meter, so the cost is about 2 * 0.6 * (30/60) = 0.6 yuan.

Precautions for the use of rice cookers:

1. The rated voltage of the product shall be consistent with the working voltage.

2. Wash the inner pot in time after use, and don't scrape the bottom of the inner pot with sharp hard objects when cleaning. After washing, wipe off the water on the outer surface of the inner pot and put it back in the shell.

3. In order to prevent poor contact between the inner pot and the electric heating plate, the following points should be paid attention to when using:

① Collision should be avoided at the bottom of the inner pot to prevent deformation.

(2) when put in the inner pot, put it in a hot plate.

(3) The inner pot and the plate of the rice cooker should be kept clean, and no sundries should be left.

4. The shell and electric heating plate should be waterproof. If water accidentally enters, they should stop using it and continue to use it after it is completely dry.

5. The rice cooker should not be used for cooking acid and alkaline food, nor should it be placed in corrosive environment.

6. Don't take out the inner pot after turning on the power, otherwise there is a danger of burning out the electric heating plate.

7. If something goes wrong, don't disassemble it at will. Please ask relevant professionals to repair it.

8. Do not connect the power plug of the rice cooker to the power distribution socket of the lamp holder or desk lamp. Because the wires of general desk lamps are relatively thin, the current carrying capacity is small, and they are easy to age or melt when heated. However, the power and current of the rice cooker are large, which will make the lamp wire heat up and cause accidents such as electric shock and fire. Baidu encyclopedia-rice cooker
