Abstract

The utility model relates to an energy-saving ceramic tank electric cooker, an electric heating element(5) inside the cooker is an assorted ceramic heating element, and the heating element(5) is arranged in a base(6), the shape, size of a heat transfer board(4) on the heating element(5) is corresponding with the lower part of the ceramic tank(1), and the bottom and the outer edge of the lower part of the ceramic tank are touchingly corresponding with the heat transfer board. A thermal insulation layer(3) is arranged in the gap between the outer heat transfer board(4) and a jacket(2). The utility model is designed reasonably and can optimize the heating transferring as well as release using. The product has a long survival life and favorable using effect, thermal efficiency is high and the safety performance is favorable, the element are matched reasonably and the manufacturing and using cost can be lowed, thus is suitable for popularizing.

Description

Energy-saving ceramic inner bag electric rice cooker

Technical field

The utility model relates to a kind of electric rice cooker, particularly a kind of energy-saving ceramic inner bag electric rice cooker.

Background technology

Electric cooker is a kind of household electrical appliance of having popularized.Electric cooker inner container commonly used generally adopts the metal material mold pressing to form, its light weight, heat conduction is fast, the heat efficiency is high, and it is easy, durable in use to clean, but its some taste of food that processes is less than ceramic liner, as cook, congee and stewing soup, therefore the ceramic liner electric rice cooker arises at the historic moment, and replaces to a certain extent.But in use, it is found that, come from the characteristic of ceramic material, also there are many problems equally in existing ceramic liner electric rice cooker: first heat transference efficiency is slow, can not be in time with the heat absorption transmission of thermoelectric heating device, thereby easy burn-out; Two to be that the heat energy of thermoelectric heating device changes too urgent for it, causes the inner bag local temperature difference excessive, thereby can explosion; It three is that the thermal conductive surface and the inner bag contact area of thermoelectric heating device is few, thereby heat-energy losses is big.

Summary of the invention

The purpose of this utility model is to provide a kind of improved energy-saving ceramic inner bag electric rice cooker for the shortcoming that overcomes above-mentioned prior art, and rationally release heat improves the quality that boils, and reduces product cost, energy savings.

The purpose of this utility model can realize by following technical measures: this electric rice cooker improves on the basis of existing product structure and forms, inner bag is a ceramic liner, thermoelectric heating device in the pot body is supporting ceramic electrical heating element, thermoelectric heating device is installed in its base, fill by heat-insulation layer, heat transfer plate is arranged above the thermoelectric heating device, the shape of heat transfer plate, big or small corresponding with the ceramic liner bottom, heat transfer plate and ceramic liner contact matching are provided with heat-insulation layer in the periphery of thermoelectric heating device, heat transfer plate and the space between the sheath.In actual applications, ceramic liner is put into a pot body, bottom and lower, outer perimeter are close to heat transfer plate, the heat of thermoelectric heating device passes to ceramic liner by heat transfer plate, and the thermoelectric heating device programming rate is more slow, and the heat accumulation function is arranged, suit and the supporting application of ceramic liner especially, heat transfer plate increases the heat-transfer area with ceramic liner again, makes its thermally equivalent, can adapt to more high-power heating needs.

Of the present utility model reasonable in design, optimize heat transferred and release and utilize effect, long product lifecycle, effect is good, heat efficiency height, security performance is good, and the member collocation has rationally reduced the production and the use cost of product, is suitable for applying.

Description of drawings

Fig. 1 is a longitudinal sectional view of the present utility model.

Embodiment

With reference to Fig. 1, this electric cooker inner container is ceramic liner [1], thermoelectric heating device [5] in the pot body is supporting ceramic electrical heating element, the employing patent No. is 02271168.6 ceramic boxlike electric heater, thermoelectric heating device [5] is installed in its base [6], fill by heat-insulation layer [7], above the thermoelectric heating device [5] heat transfer plate [4], the shape of heat transfer plate [4], size is corresponding with ceramic liner [1] bottom, the bottom of ceramic liner [1] and lower, outer perimeter are close to heat transfer plate [4] contact matching, and heat transfer plate [4] upper end is connected and fixed on sheath [2] thermoelectric heating device [5], between the periphery of heat transfer plate [4] and the sheath [2] fixed gap is arranged, be provided with heat-insulation layer [3] in the space, improve the heat efficiency.Through above technical measures, the ceramic liner electric rice cooker can be done 700～1100W product.
