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

Energy-saving electric cooker

Technical field

The present invention relates to a kind of electric cooker, especially can save the energy-saving electric cooker of electric energy.

Background technology

At present, in family, while cooking rice, different because of everyone taste, someone wishes to cook eight-treasure rice pudding, and it is harder that someone wishes that rice is cooked, and someone wishes softer, and somebody wishes to drink congee, but current electric cooker can only be wherein a kind of simultaneously.Working clan is just by the switch opens of electric cooker before working in morning, it is that stewing a period of time could be well-done again after then switch opens heats automatically closure that electric cooker is cooked rice, rice is cooked the ripe rear heating and heat preserving function by electric cooker makes also can be able to eat reeky rice noon, in these processes, heat in pot constantly scatters and disappears, switch is constantly opened to start to heat and is heated to rice, and these all cause the serious waste of electric energy.Chinese Patent Application No. CN201020225831 discloses a kind of energy-saving electric rice pot, in its annular gap between inside and outside pot pot shell and between inside and outside pot pot shell bottom surface in the cavity except electric heating plate, all load be provided with insulation material be used for insulation, but this heat preserving mode is very harsh to the requirement of insulation material, quality can not be too large, and cost can not be too high, must take into account volume, cause being difficult to find such material, heat insulation effect is also limited simultaneously.

Summary of the invention

The object of this invention is to provide a kind of energy-saving electric cooker, it saves electric energy, also can make the rice of several tastes simultaneously.

The technical solution adopted for the present invention to solve the technical problems is: electric cooker has housing, and housing surrounds heat-preservation liner, and heat-preservation liner surrounds common inner bag, heat-preservation liner can be one, also can be several, common inner bag can be one, can be also several.Heat-preservation liner is the container of hollow, has opening on heat-preservation liner.Each common inner bag has corresponding heat-generating disc, temperature controller and switch, and its principle of heating and control mode and ordinary electric rice cooker are similar, heat-preservation liner internal heater rice heating, electrothermal tube for example, switch steam cock.A common inner bag also can be set for burning congee Special inner container, the switch of this Special inner container adopts temp controlled delay switch, and after reaching the temperature of cooking gruel accordingly, time delay disconnects for 20 to 40 minutes.

The present invention is when concrete application, it is one that heat-preservation liner quantity can be set, common inner bag is 2, while cooking at ordinary times, in 2 common inner bags, add respectively the water of rice and different capabilities, can make 2 kinds of rice that soft or hard is different, by the opening on heat-preservation liner, in heat-preservation liner, add water simultaneously, cover the lid on casing of electric cooker, the switch of opening 2 common inner bags starts to cook.When cooking, the water in the heat insulation inner bag that common inner bag distributes absorbs, and the temperature of the water in heat-preservation liner raises.After rice boils, switch is automatically closed, rice temperature in common inner bag slowly declines, water in heat-preservation liner is high specific heat capacity material, stores more heat transfer, and its heat loss is relatively slow, the temperature difference of the relative environment of inner bag of cooking rice of the Temperature Difference Ratio ordinary electric rice cooker of the relative heat-preservation liner of rice temperature in common inner bag is little, because the speed of the larger heat transfer of the temperature difference is larger, the heat loss of the rice in heat-preservation liner is just slower, and its result is exactly relatively to have improved heat-insulating property.Like this, within the regular hour, switch starts the frequencies go lower to rice heating and thermal insulation automatically, and the heat time shortens, and has saved electric energy.When user goes home to have a meal, hot water in heat-preservation liner can be used for using, as washed one's hands, wash plate etc. with rice, also can open the switch activated heater on heat-preservation liner, by temperature in heat-preservation liner, very high hot water short time burns till boiling water and is used for drinking or using.The mode of heating of common inner bag of the present invention and heat-preservation liner, Temp. control method, switch setting and and the connection of power supply, person of ordinary skill in the field can implement easily, has not just described in detail.

The invention has the beneficial effects as follows: the water in the heat insulation inner bag that common inner bag distributes absorbs, the water heat loss of high specific heat capacity is relatively slow, the temperature difference of the relative environment of inner bag of the Temperature Difference Ratio ordinary electric rice cooker of the relative heat-preservation liner of food temperature in common inner bag is little, the heat loss of the food in heat-preservation liner is just slower, relatively improved heat-insulating property, shortened the total time of Heat preservation, saved electric energy, a plurality of common inner bags also can be done dissimilar rice simultaneously, produce hot water simultaneously, improved ease of use.
