Abstract
The utility model relates to a high-energy-efficiency heating disc, which is used for the field of kitchen appliances such as electric cookers, electric pressure cookers, electric chafing dishes and the like. The high-energy-efficiency heating disc comprises an annular support and an annular heat conducting panel, an electric heating plate and an insulation heat transmission ring are disposed between the support and the heat conducting panel, wherein the insulation heat transmission ring is arranged between the heat conducting panel and the electric heating plate, the electric heating plate is annular, and the support is fixedly connected with the heat conducting panel so that the electric heating plate and the insulation heat transmission ring are fixed between the support and the heat conducting panel. The heat conducting panel is made of aluminum materials or aluminum alloy (or other metal materials with fast heating), and the support is made of ceramic materials. In addition, the high-energy-efficiency heating disc has the advantages of large heating area, uniform heating, fast heat transmission, few heat loss, high-energy-efficiency heat transmission, long service life, capability of reducing aluminum materials, and low cost.
Description
Technical field
The utility model relates to a kind of high energy efficiency heat-generating disc, is applicable on electric cooker, electric pressure cooker, the electric chafing dish and uses.
Background technology
The heat-generating disc of present electric cooker, electric pressure cooker, electric chafing dish all adopts aluminium to make, electrothermal tube die casting in aluminium, the electrothermal tube heating of energising back and by aluminium with the heat transferred inner bag, its shortcoming is that efficiency is low, the life-span short; Reason mainly is that the heat of existing heat-generating disc 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, heat-generating disc 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 in order to solve the problem that the efficiency that exists in the existing heat-generating disc is low, the life-span is short, 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 heat-generating disc.
The purpose of this utility model is achieved in that a kind of high energy efficiency heat-generating disc, comprise the support of annular and the heat conduction panel of annular, it is characterized in that being provided with between described support and the heat conduction panel electric heating piece and insulation heat transfer ring, wherein insulation is conducted heat to encircle and is arranged between described heat conduction panel and the electric heating piece, and described electric heating piece is an annular; Fixedly connected between described support and the heat conduction panel and described electric heating piece and the insulation ring that conducts heat is fixed between support and the heat conduction panel.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.
Described support is provided with cannelure, and described electric heating piece and insulation are conducted heat to encircle and be placed in this cannelure.The electric heating piece of annular encircles the back that is stacked together with the insulation heat transfer and matches with this cannelure.
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 support adopts ceramic material 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.
Owing to adopted technical scheme described in the utility model, because being large tracts of land and heat conduction panel, electric heating piece conducts heat, so heating area increases greatly, be heated evenly, and good heat-transfer; Electric heating piece can be not violent, long service life; Because support adopts ceramic material, 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.Support uses ceramic material, significantly reduces the use of aluminium or other metal, and the partiting thermal insulation function is arranged, and can bring tangible reduction effect to the temperature that the bottom produced of product, ensures security of products and life-span.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
It shown in the accompanying drawing structural representation of an embodiment of the present utility model.
Among the figure 4, the insulation ring that conducts heat, 1, the heat conduction panel, 12, the hole, 22, inner edge, 23, outer rim, 13, detain the wing outward, 11, the interior button wing, 2, support, 21, screw, 3, electric heating piece.
Embodiment:
