The beneficial effects of the utility model are: can shorten the cooking time on the basis of power and energy saving, give the user some facilities that existing electric-heating cooking utensil can't give, the utility model adapts to China's national conditions at present very much, be applicable to the multistage layer personage of society, in case popularize, reason according to long-pending husky Chengqiu, make huge contribution for low-carbon energy-saving surely, can the explanation problem from following four aspects: 1, with the existing condition that has reduced heat energy loss with the different structure structure of purposes electric-heating cooking utensil, having increased heater conducts heat to the approach of food, make heat can use conduction, convection current, number of ways solids such as the airborne transmission of steam, comprehensive, pass to fuel value of food rapidly and equably, reach the quick and purpose of energy saving of cooking, and existing electric heating steams, boil only generate heat limited contact the between the solid in the chassis and the interior the bottom of a pan of cooker, cause and can only conduct heat to interior pot (heat-generating pipe or heating wire with generate heat between the chassis also is like this) with " conduction " this a kind of heat transfer path, only this, the present invention just should be significant.2, different with existing electric-heating cooking utensil structure structures can dwindle overall volume under the prerequisite of not dwindling dischargeable capacity, reach the purpose of fully, efficiently utilizing heat energy.3, can be with a few the most original simple part, minimum manufacturing cost is included all functions of the same purposes cooker of existing five-star intelligence, on the contrary, existingly but can't accomplish the some very practical action functions of the utility model with the senior cooker of purposes intelligence.4, Du Te heat transfer type and particular structure are constructed many superior functions and the effect that brings, and cater to very much the national conditions of China, have wide suitable crowd.

1, heater of the present utility model is taken shelter in outer pot bottommost with in the water that can not contact the bottom of a pan wall and be as the criterion, the water of useing the heating chassis as floods 1/5th to five/everywhere (also not contacting with the interior the bottom of a pan as required) below the inner pot outer wall according to the needs of different foods or different quantity of food, the energising initial stage, as long as some heats are arranged, water is just used multiple heat transfer types such as conduction and convection current heat is passed to the interior food of interior pot rapidly equably, the water and the food in the interior pot that serve as the chassis that generates heat almost are to be heated to 100 degree simultaneously, and then the fastening pressue device will further heat (can reach 300 degree) to the water pressurization of serving as the chassis that generates heat, high pressure, high-temperature fluid heating chassis just can be more initiatively, apace heat is passed to food equably, so a variety of foods this have the fastening pressue device use water as the heating chassis electric-heating cooking utensil in, soon can allow its outage for a moment vexed more very soon as long as several minutes safety-valves of energising are jet, just can take out edible, existing electric-heating cooking utensil can only be to having obtained the interior pot fastening pressurization of suitable heat, the heat that metal heating chassis is produced can't allow heat is quicker passes to interior pot more efficiently with the method for " pressurization ", can only be with strengthening electrical power, increase heating chassis self temperature, the mode of using down the one side contact allows metal heating chassis utilize limited contact-making surface passively, conduct heat to interior pot with " conduction " this a kind of heat transfer path, this just unavoidable heat transfer slowly, food is heated inhomogeneous, heat escape waste is serious or the like, but also therefore can cause with metal do the heating chassis than water with lacking much the service life of the electric-heating cooking utensil on the chassis that generates heat, there is cooker to solve this problem with blowing, but this had both increased manufacturing cost, increase the meeting of heat escape machine again, increase power consumption again, get half the result with twice the effort.

2, use water as the more compact structure of the electric-heating cooking utensil on heating chassis than existing metal heating chassis cooker, the overall volume of same big dischargeable capacity is smaller and more exquisite, as same air-conditioner or warmer different action effects and different power consumption data in cubicle and stateroom performance, use water as the heating chassis and with the heat energy of the electric-heating cooking utensil that metal is done the heating chassis, to same quantity, can produce visibly different action effect with the food of kind with unit of quantity.A kind of cooker with the function of cooking as Fig. 1 and/or figure (13) illustrated embodiment can be made just can dwindle nearly 1/3rd than a lot of existing electric-heating cooking utensil overall volume on the equally big basis of dischargeable capacity with purposes.The structure of the existing tower food steamer of electric heating is looser than the utility model, accomplish that various food is with the ripe overlay space that can only make progress, and the process of whole shortening food can only be depended merely on the heat transfer effect of steam, and can not use the fastening device that adds high pressure, allow inside produce HTHP, so the processing steamed wheaten foods is escaped because of heat energy, waste is serious, heat transfer path is single, and lower than functioning efficiency of the present utility model.

3, the utility model is cheap for manufacturing cost, action function is but many than existing electric-heating cooking utensil, as Fig. 1 or/and embodiment shown in Figure 13 is the cooker with the function of cooking made of basis, only need enable very ripe, disclosed automatic outage already and height gear regulation technology, add the measuring cup and the operation instruction in a paper water consumption control time of a water gaging amount rice, just can realize assisting and draw together existing whole all functions, have now on the contrary and but can't accomplish some very practical action function of the present utility model with the senior cooker of purposes intelligence with purposes high-grade intelligent cooker.

4, Modern China is no matter be cities and towns or rural area, the mountain area, can both see two ancestrals, one grandson's (a perhaps ancestral one grandson) of magnanimity existence stay-at-home family everywhere, can both see ubiquitous two mouthful of one son (woman) family everywhere, the stay-at-home family in rural area particularly in these families, according to my conscientiously investigation and observation, their economic pursuit actual effect, the equally also cooker of the senior luxurious intelligence that can only cook, they can never buy, and the electric-heating cooking utensil that uses water as the low manufacturing cost on heating chassis just in time can be in multipurpose, fast, need not increase cooker on the basis that economize on electricity saves money and the cooking time just can accomplish that soft or hard is with ripe, diet contradiction between the fine solution grandparent and grandchild, the cities and towns office staff can accomplish at short notice that also food is with ripe, can live by the modern fast pace of fine adaptation, this cooker is constructed under the prerequisite of same fast energy-saving not changing structure, increase the volume volume, also can satisfy the needs of the big family that many people have a meal together; In addition, Modern China also has a no small very large group of number that comprises the inventor: comprise the higher personnel of blood-fat and blood sugar, the cardiovascular and cerebrovascular patient, be afraid of fat fat-reducing personnel, the youth women that likes to be beautiful, also have some high-level managements or the like, just popular a kind of late night snack or other times are only had some the fashionable eating habit of steaming vegetables in the middle of them, but other members in this eating habit family can not imitate for a long time, original intention of the present utility model just in time can easily satisfy the independent specific demand of these large quantities of people quickly just in time for these people make to measure.To sum up, the utility model is all made huge contribution in the low-carbon (LC) life of advocating for the whole world surely.
