What is the principle of electric pot heat preservation?

Many electric pots have a heat preservation function, and heat preservation has basically become one of the standard functions of household electric cookers. After the food is cooked, turn on the heat preservation switch of the electric cooker, and it will enter the heat preservation mode, so that the temperature of the food in the pot is always maintained at 5060 It is about the temperature, especially in winter when the weather is cold, so that you can always eat hot meals. So, what is the principle of electric pot heat preservation? Does electric pot heat preservation consume a lot of electricity?

The principle of electric heating pot heat preservation

Many electric pots above 28CM have a heat preservation function. The heat preservation function is composed of an internal heat preservation temperature controller and an external heat preservation switch. When you need to keep the food in the pot, you only need to turn on the heat preservation switch to keep the temperature in the pot and control the temperature. When the electric heating pot is lower than the temperature of about 60 degrees set by the heat preservation thermostat, the thermostat controls the 500W heating tube to start heating. When the temperature exceeds about 60, the thermostat will Cut off the power supply, and the heating tube stops heating. The heat preservation function of the electric heating cooker is mainly controlled by a heat preservation temperature controller. The principle is relatively simple and the quality stability is good.

Matters needing attention

Although the heat preservation of the electric heating pot is easy to use, it must be used correctly, and there will be certain problems with the wrong method of use.

1. Long-term heat preservation is easy to breed bacteria

Below 60°C is the temperature at which bacteria are most likely to breed. Long-term use of an electric pot to keep food is easy to breed bacteria, so use an electric pot to keep food warm for no more than 2 hours.

2. The heat preservation must be guarded

The electric pot is in the heat preservation state. The electric pot is always in working condition. To prevent accidents, do not use the electric pot heat preservation function in the home for a long time without people.

3. The hidden danger of no water insulation

Electric hot pots can keep soup, porridge, stews, and stir-fry dishes warm, but you must ensure that the food has a certain amount of soup when keeping warm, and try not to keep some dry foods without soup. Dry foods are heated in an electric hot pot and burn easily. It is easy to shorten the service life of the electric heating pot.
