Abstract
The utility model relates to an energy efficient electric pressure cooker, which is large in heating area, uniform in being heated, fast in heat transfer, long in service life, less in heat loss and high in reliability, and comprises a shell, a pot cover subassembly, an inner pot, an external pot, an electric hot tray and a pressure switch, the energy efficient electric pressure cooker is characterized in that the electric hot tray comprises a ring-shaped bracket and a ring-shaped heat conduction panel, a ring-shaped accepting groove is arranged along a surface of the ring-shaped bracket, a heat insulating material is filled in the accepting groove, a ring-shaped electric heating plate is placed at upside of the heat insulating material, the upside of the heat insulating material is a ring-shaped insulating heat-transfer ring, and the ring-shaped heat conduction panel covers the ring-shaped insulating heat-transfer ring; and the bracket is fixedly connected with the heat conduction panel so as to fix the heat insulating material, the electric heating plate and the insulating heat-transfer ring in the accepting groove of the bracket. When the electric heating plate is conducted, heat is transferred to the heat conduction panel via the insulating heat-transfer ring, since the electric heating plate is a ring-shaped heater, power of unit area is low, and heat conduction efficiency is high.
Description
Technical field
The utility model relates to a kind of electric pressure cooker, particularly relates to a kind of electric pressure cooker with high energy efficiency electric hot tray.
Background technology
Existing electric pressure cooker comprises shell, pot cover component, interior pot, outer pot, electric hot tray and pressure switch, 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 pot in the heat transferred, 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 pressure 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 electricity pressure cooker.
The purpose of this utility model is achieved in that a kind of high energy efficiency electricity pressure cooker, comprise shell, pot cover component, interior pot, outer pot, electric hot tray and pressure switch, 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 11, air bleeding valve, 1, pot cover component, 2, interior pot, 21, outer pot, 22, shell, 23, middle ring, 3, electric hot tray, 4, pressure switch; 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 electricity pressure cooker comprises shell 22, pot cover component 1, interior pot 2, outer pot 21, electric hot tray 3 and pressure switch 4, 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.
