Description

Multifunctional electric heating rice cooker

The present invention relates to a kind of electric cooking pot, more particularly, it is a kind of multifunction electric saucepan of water isolation cooking automatic electric limiting.

Electric cooker apparatus such as electric cooker, electronics crock, tonic electric cooker use widely in daily life.The common defects of these electric cooker apparatus is that power consumption is many, not energy-conservation, function singleness, only be suitable for steamed rice as electric cooker, though electronics crock power designs is less, but still do not reach the purpose of temperature fire sealing, stew in the porcelain courage does not often reach boiling point, does not meet hygienic requirements, and the tonic electric cooker is the patented product of inventor's design in 90 years, once obtained " Chinese Edison invents a glass gold medal ", but its function singleness.

In view of the above-mentioned defective of state of the art, the purpose of this invention is to provide a kind of energy water isolation cooking, can obtain the best electric cooking pot of stewing goods matter; Second purpose of the present invention provides the energy-conservation electric cooking pot of a kind of energy automatic electric limiting; The 3rd purpose of the present invention provides a kind of electric cooking pot with multiple function.

These purposes of the present invention realize by following measure.Stewed core at first is set in electric cooking pot.Stew places stewed in-core, and stewed core places a pot interior water, keeps 100 ℃ of water isolation cooking tonics with boiling water, and among steam surrounded, inner and outer air pressure unanimity, Primordial Qi were difficult for leaking stewed core fully, thereby can obtain best stewed goods matter.Second measure that the present invention takes is to be provided with the automatic reduction voltage circuit of temperature control, when water in the pot seethes with excitement, this circuit can make load voltage reduce to and give decides voltage, for example, reduce to half of rated voltage, load current also reduces half, and load is at this moment only kept fluidized state with 1/4 rated power, can economize on electricity 75%.The pressing push button need add when high-power, as long as can obtain total power.Electric cooking pot of the present invention is changed the defective of existing electric cooking appliance function singleness, both can cook, steam bag, Baoshang, stewes tonic, fry in shallow oil Chinese medicine, can also work as chafing dish.

Below with reference to accompanying drawings and most preferred embodiment, the present invention will be described in more detail.
