Office workers turn on the switch of the rice cooker before going to work in the morning. The rice cooker cooks rice after the switch is turned on for heating, then it is automatically closed and then stewed for a period of time before it is cooked. The function makes it possible to eat hot rice at noon. During these processes, the heat in the pot is continuously lost, and the switch is constantly turned on to start heating to heat the rice, which leads to a serious waste of electric energy.

Abstract
The invention discloses an energy-saving electric cooker which can save electric energy. The energy-saving electric cooker is provided with a shell, the shell surrounds a heat preservation inner container, the heat preservation inner container surrounds common inner containers, an opening is formed in the heat preservation inner container, the common inner containers can be arranged, and therefore rice of different tastes can be cooked at the same time. Water is added to the heat preservation inner container through the opening before cooking, heat dissipated by the common inner containers is absorbed by the high-specific-heat-capacity water in the heat preservation inner container in the cooking process, and the temperature of the water in the heat preservation inner container rises. When heat preservation is carried out on the rice after the rice is cooked thoroughly, the temperature difference of the temperature in the common inner containers relative to the heat preservation inner container is smaller than that of an inner container of a common electric cooker relative to the environment, and therefore the larger the temperature difference is, the larger the heat transfer rate is, and the heat loss of food in the heat preservation inner container is slow. The heat preservation performance is relatively improved, a switch is automatically started, the frequency for heating and carrying out heat preservation on the rice is reduced, heating time is shortened, the electric energy is saved, hot water is generated at the same time, and use convenience is improved.
Description
technical field [0001] The invention relates to an electric rice cooker, in particular to an energy-saving electric rice cooker capable of saving electric energy. Background technique [0002] At present, when making rice at home, because everyone has different tastes, some people want to make eight-treasure rice, some want the rice to be harder, some want it to be softer, and some want to drink rice porridge, but the current electric rice cooker can only do it at the same time. kind of. Office workers turn on the switch of the rice cooker before going to work in the morning. The rice cooker cooks rice after the switch is turned on for heating, then it is automatically closed and then stewed for a period of time before it is cooked. The function makes it possible to eat hot rice at noon. During these processes, the heat in the pot is continuously lost, and the switch is constantly turned on to start heating to heat the rice, which leads to a serious waste of electric energy...
