Abstract
The utility model relates to a thermal insulation heating pot, which is composed of a pot body, a heating tray, a heating resistance, a base, etc. The heating resistance is installed in the heating tray, and a cavity is arranged between the heating tray and the bottom of the pot body; the heat transferring energy-saving materials of tin, bismuth, etc., are installed in the cavity. An insulating plate is installed between the heating tray and the base, and heat-insulating materials are filled between the insulating plate and the heating tray. The utility model adopts the structure that the heat transferring energy-saving materials of tin or bismuth are filled between the pot bottom and the heating tray, and the defect of air heat transfer is avoided; compared with the existing prior art, the utility model has the characteristics of energy saving, time saving, fast temperature rise, high temperature, etc.
Description
The utility model relates to electric food warmer.
That electric food warmer has is easy to use, cleaning, clean, pollute characteristics such as few, be subjected to liking of numerous users deeply.But the essential structure of existing electric food warmer is similar to electric cooker, the major defect of its existence is that the bottom of a pan and heat-generating disc are separated, in use, an air heat transfer layer is arranged between the two, this air heat transfer layer has influenced effective conduction of heat, cause that the thermal efficiency reduces, energy loss is big, is directly connected to result of use.
The purpose of this utility model is that design is a kind of with the energy-conservation heat-transfer matcrial of installation between the bottom of a pan and the heat-generating disc, and exempts the heat preserving type electric food warmer of air heat transfer layer.
The art designs scheme of the utility model heat preserving type electric food warmer is: be made up of institutes such as pot body, heat-generating disc, heating resistor and bases, so-called heating resistor is installed in the heat-generating disc, between heat-generating disc and the bottom of pot body die cavity is arranged, energy-conservation heat-transfer matcrials such as tin or bismuth are installed in the die cavity.
Heat preserving type electric food warmer of the present utility model is installed thermal insulation board between heat-generating disc and base, fill up insulation material between thermal insulation board and heat-generating disc.
Heat preserving type electric food warmer of the present utility model, its pot body is cast by the pig iron, and heat-generating disc is made by aluminum alloy materials, and insulation material is asbestos etc.
The utility model discloses a kind of electric food warmer,, exempted the heat insulation defective of air to fill up between the bottom of a pan and the heat-generating disc after the tin of energy-conservation heat transfer or the heating of bismuth material, compared with the prior art, have thermal efficiency height, the heating temperature rise is fast, the temperature height, obvious energy conservation, characteristics such as save time.
Fig. 1 is the utility model heat preserving type electric food warmer structural representation.
Below in conjunction with Fig. 1 embodiment of the present utility model is done detailed explanation.
The pot body; 2. shell; 3. heat-generating disc; 4. die cavity; 5. heating resistor; 6. heat-insulation layer; 7. thermal insulation board; 8. base; 9. air chamber.
The utility model relates to a kind of heat preserving type electric food warmer, casts pot body 1 with the pig iron, and a shell 2 is arranged, the shell base 8 of can ining succession is made heat-generating disc 3 by aluminum alloy materials, at die cavity 4 of heat-generating disc upper wall processing, fill materials such as tin or bismuth in the die cavity, cold back becomes solid, because of fusing point low, one is heated into liquid, is full of among the die cavity, has exempted air, air has heat-blocking action, so the air heat-transfer effect is poor, tin or bismuth heat-transfer effect are good, obvious energy conservation.Heating resistor 5 is installed, as resistance wire in heat-generating disc.In order further to improve the thermal efficiency, fill up relevant insulation material 6 between the installation thermal insulation board 7 between base 8 and heat-generating disc 3, thermal insulation board and heat-generating disc, as asbestos, expanded perlite etc.And between the edge of pot body 1 and shell 2, air chamber 9 being arranged, air chamber plays insulation effect to pot body top, makes the meal of being done upper and lower well-done together.Therefore, this pot is specially adapted to cook.This technology can make the thermal efficiency improve more than 35%, saves the cooking time about 1/2nd.
