Abstract
The utility model relates to an electric rice cooker with high energy efficiency, which has the advantages of large heating area, uniformity of heating, rapidity of heat transfer, long service life, less heat loss and high reliability. The electric rice cooker comprises a casing, a cooker cover component, a cooker inner container, an electric heating disc and a temperature controller, and is characterized in that the electric heating disc comprises a ring-shaped support and a ring-shaped heat-transfer face plate, a ring-shaped accommodating groove is formed on the surface of the ring-shaped support, an electric-insulating and heat-insulating material is packed inside the accommodating groove, a ring-shaped electric heating sheet is arranged on the upper side of the electric-insulating and heat-insulating material, an annular electric-insulating and heat-insulating ring is arranged on the upper side of the electric heating sheet, the ring-shaped heat-transfer face plate covers the annular electric-insulating and heat-insulating ring, and the support and the ring-shaped heat-transfer face are fixedly connected together to fix the electric-insulating and heat-insulating material, the electric heating sheet and the electric-insulating and heat-insulating ring inside the accommodating groove. When the electric heating sheet is energized, heat is transferred to the heat-transfer face plate through the electric-insulating and heat-insulating ring, and since the electric heating sheet is a ring-shaped sheet-like heating body, the power per unit area is reduced and the heat transfer efficiency is improved.
Description
Technical field
The utility model relates to a kind of electric cooker, particularly relates to a kind of electric cooker with high energy efficiency electric hot tray.
Background technology
Existing electric cooker comprises shell, pot cap assemblies, pot courage, electric hot tray and temperature controller, wherein electric hot tray all adopts aluminium to make, electrothermal tube die casting in aluminium, the heating of energising back electrothermal tube and by aluminium with heat transferred pot courage, its shortcoming is that efficiency is low, the life-span short; Reason mainly is that the heat of existing electric hot tray concentrates on electrothermal tube, heating area is little, concentrated, inhomogeneous, the unit are power of electrothermal tube causes the heat in the electrothermal tube in time outwards not transmit greatly, and owing to adopt aluminium many, electric hot tray body caloric receptivity is big, heat loss is serious, thereby causes its efficiency low, and phenomenons such as crackle, distortion, booster, burning dish appear in the disk body of electric hot tray easily.
Summary of the invention
The purpose of this utility model is for the problem that efficiency is low, the life-span is short that exists in the electric hot tray that solves existing electric cooker, and provide that a kind of heating area is big, fast, the long service life of being heated evenly, conducting heat, heat runs off less, reliability is high high energy efficiency electric cooker.
The purpose of this utility model is achieved in that a kind of high energy efficiency electric cooker, comprise shell, pot cap assemblies, pot courage, electric hot tray and temperature controller, it is characterized in that described electric hot tray comprises the support of annular and the heat conduction panel of annular, be provided with the storage tank of annular along this ring support surface, in this storage tank, fill the insulation heat-barrier material, this insulation heat-barrier material upside is placed the annular electro backing, this annular electro backing upside is annular insulation heat transfer ring, and described annular heat conduction panel covers this annular insulation heat transfer ring; Fixedly connected between described support and the heat conduction panel and described insulation heat-barrier material, electric heating piece and the insulation ring that conducts heat is fixed in the storage tank of support.During the electric heating piece energising, heat conducts heat to encircle through insulation and is delivered to the heat conduction panel, because electric heating piece is the sheet-shaped heating element of annular, the power on the unit are is less, the heat conduction efficiency height.
The inner edge of described heat conduction panel and outer rim are respectively equipped with buckles inner edge and the outer rim that the wing fastens described support.
Described insulation heat transfer ring is mica sheet or heat-conducting silicone grease.But be not limited only to mica sheet or heat-conducting silicone grease.
The power supply lead wire of described electric heating piece is fixed in the described support.
Described heat conduction panel adopts the metal material of aluminium or other good heat-transfer to make.
Described electric heating piece is made of mica sheet and heating wire, and wherein heating wire is wrapped in this mica sheet surface.
Described insulation heat-barrier material is high temperature heat-barrier materials such as ceramic fibre or alumina silicate fibre.
Because having adopted technical scheme described in the utility model, electric heating piece is that large tracts of land and heat conduction panel conduct heat, so heating area increases greatly, be heated evenly, and good heat-transfer; Electric heating piece can be not violent, long service life; Owing to fill the insulation heat-barrier material in the cannelure of support, reach the partiting thermal insulation purpose simultaneously, reduce the loss of heat, heat focuses on the heat conduction panel so can reach the high energy efficiency effect.Use insulation heat-barrier materials such as ceramic fibre or alumina silicate fibre in the cannelure of support, significantly reduce the use of aluminium or other metal, and the partiting thermal insulation function is arranged, can bring tangible reduction effect, ensure security of products and life-span the temperature that the bottom produced of product.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the internal structure schematic diagram of an embodiment of the present utility model.
Fig. 2 is the profile of electric hot tray among Fig. 1.
Among the figure 90, the steam valve assembly, 95, shell, 93, the pot courage, 92, stay-warm case, 96, electric hot tray, 98, temperature controller, 91, pot cap assemblies; 6, the insulation ring that conducts heat, 7, the heat conduction panel, 72, the hole, 81, inner edge, 82, outer rim, 73, detain the wing outward, 71, the interior button wing, 8, support, 5, electric heating piece, 9, the insulation heat-barrier material.
The specific embodiment:
See shown in Figure 1ly, described high energy efficiency electric cooker comprises shell 95, pot cap assemblies 91, pot courage 93, electric hot tray 96, stay-warm case 92, steam valve assembly 90 and temperature controller 98, and wherein the internal structure of electric hot tray 96 is seen Fig. 2.
See Fig. 2, electric hot tray comprises the metallic support 8 of annular and the metal heat-conducting panel 7 of annular, be provided with the storage tank of annular along ring support 8 surfaces, in storage tank, place insulation heat-barrier material 9---can be asbestos, glass fibre, ceramic fibre or alumina silicate fibre, the upside of insulation heat-barrier material 9 is an annular electro backing 5, the upside of annular electro backing 5 conducts heat for the annular insulation and encircles 6---and can be mica sheet or heat-conducting silicone grease, annular heat conduction panel 7 covers the annular insulation ring 6 that conducts heat, and buckle the wing 71 in the inner edge of heat conduction panel and outer rim are respectively equipped with and the outer wing 73 of buckleing fastens the inner edge 81 of support and outer rim 82 and the heat-barrier material 9 that will insulate, electric heating piece 5 and insulation heat transfer ring 6 are fixed in the storage tank of support.Wherein heat conduction panel 7 preferably uses aluminium.During the electric heating piece energising, heat conducts heat to encircle through insulation and is delivered to the heat conduction panel, because electric heating piece is the sheet-shaped heating element of annular, the power on the unit are is less, the heat conduction efficiency height.
