Abstract
The utility model provides an infrared electrothermal disk for electric rice cooker. The structure characteristics of the infrared electrothermal disk for electric rice cooker is a lamellar structure; the upper layer is a far infrared metal plate; the layers downward are successively the insulating layer of a built-in electric heating element, a ceramic plate, a heat-insulating layer and a metal chassis; the edge of the metal chassis is connected with the far infrared metal plate to form an integral electrothermal disk. Because the infrared electrothermal disk for electric rice cooker adopts the far infrared metal plate and heat insulation measures, compared with the present electric hot tray, the infrared electrothermal disk for electric rice cooker has the advantages of rapid heating speed, high heat efficiency and little thermal loss. The infrared electrothermal disk for electric rice cooker is suitable for electric rice cookers and homogeneous cooking appliances to manufacture electrothermal disks.
Description
The utility model relates to the electric hot tray that a kind of electric cooker is used, particularly a kind of far-infrared electric dish.
In prior art, electric cooker mainly is made of aluminium matter heat transfer dish and built-in electric heating element with electric hot tray, utilizes the logical peraluminous heat transfer dish of electric heating element heating to conduct heat electric cooker pot courage is heated.Its structure and heat transfer type do not have much changes basically since electric cooker comes out.This electric hot tray has 2 weak points: the first adopts conduction pattern to transmit heat, and the heat efficiency is not high; It two is that the non-conducting surface of electric hot tray bottom is not taked provision for thermal insulation, and thermal loss is bigger.Particularly just tending to adopt the ceramic pot courage at present, because its heat conductivility is poor more than aluminium matter pot courage, the shortcoming of above-mentioned electric heating electric hot tray is just more obvious.
The purpose of this utility model is to overcome the deficiency of existing electric hot tray, provides a kind of heat efficiency higher and far-infrared electric dish that thermal loss is little.
Task of the present utility model realizes as follows: the shape of this electric hot tray is roughly identical with existing electric hot tray, the center has the hole of laying thermostat, electric heating element is equipped with in inside, different is that this electric hot tray is a layer structure, the upper strata is the far infrared metallic plate, the second layer is equipped with the heat conduction of electric heating element, the insulation material layer of heatproof in being, the 3rd layer has been the ceramic wafer of supporting and heat-blocking action, the 4th layer is insulation material layer, layer 5 is a metal chassis, is connected with the far infrared metallic plate by its dish edge upper end to make each layer be combined into the electric hot tray of an integral body.
As everyone knows, far infrared radiation is the higher a kind of heat transfer type of the heat efficiency, because upper strata of the present utility model is the far infrared metallic plate, after the electric heating element heating, not only play conduction of heat, but also give off far infrared, the food in pot courage is further heated; In addition, taked provision for thermal insulation again at third and fourth layer.Therefore, the utility model compares with existing electric hot tray that to have firing rate fast, the high and little advantage of thermal loss of the heat efficiency.
Below in conjunction with accompanying drawing structure of the present utility model and enforcement are further described.
Fig. 1 is the cutaway view of a kind of concrete structure of the utility model.
With reference to Fig. 1, at metal chassis (6) insulation material layer (5) is set, this insulation material layer (5) can be selected alumina silicate fibre, expanded perlite and leech rock etc. for use, but the most handy alumina silicate fibre both can play good heat-blocking action, can make the reflector of heat again.In order to make this one deck do relatively closely, can add low amounts of water glass and make binding agent, and then put ceramic wafer (4) alumina silicate fibre is compressed.Go up placement electric heating element (3) at ceramic wafer (4), and on this layer, apply insulating material.For reducing the height of this insulating barrier (2), optionally make electric heating element (3) with heating wire, insulating barrier (2) the most handy aluminum phosphate and carborundum allotment form, and not only insulate but also high temperature resistant.Before insulating barrier (3) solidifies as yet fully, do not put far infrared metallic plate (1), make it to fit tightly, improve thermal conductivity.Far infrared metallic plate (1) can adopt and carry out heated oxide after the corrosion resistant plate punch forming again on its surface and handle and make.Because stainless steel contains elements such as iron, chromium, nickel, cobalt, its oxide is exactly reasonable far-infrared radiation material.Thickness of oxide layer with 0.3～0.5 millimeter for well.The outer rim of far infrared metallic plate (1) preferably flange formation downwards one is coiled edge (7) and is had oblong aperture (8) at the first-class branch of dish edge (7), go up the corresponding sheet pin (9) that is provided with disjunctor at metal chassis (6), allow sheet pin (9) be inserted in the oblong aperture (8) and also turn over downwards together, make each layer connect into the electric hot tray of an integral body.The most handy aluminium sheet of metal chassis (6) is stamped to form, and its light weight is again good thermal radiation reflector simultaneously, can further reduce thermal loss.Support foot (10) and power-line terminal (11) also are housed, this electric hot tray to be installed and to be connected external power in the bottom of metal chassis (6).In order further to improve the heat efficiency, the edge of whole electric hot tray can upwards turn over and form a dish edge (12), to increase the electric hot tray contact area of pot courage down, in addition, the electric hot tray of this structure can also avoid the bottom of ceramic pot courage and courage wall to take place because of the inhomogeneous situation about ftractureing in switching place easily of being heated, the height of dish edge (12) with 10～20 millimeters for well
This hair is novel to be particularly suitable for making the electric hot tray that electric cooker is used, and can also be used to make the electric heater of similar cooking appliance.
Claims (6)
1, the electric hot tray used of a kind of electric cooker, include electric heating element, the center has through hole, the disk body that it is characterized in that electric hot tray is a sandwich construction, and the upper strata is far infrared metallic plate (1), and the second layer keeps heat conduction, the heatproof insulating material layer (2) of electric heating element (3) in being, the 3rd layer is ceramic wafer (4), the 4th layer is insulation material layer (5), and layer 5 is metal chassis (6), is connected with far infrared metallic plate (1) by its dish edge upper end to make each layer be combined into the electric hot tray of an integral body.
2, electric hot tray according to claim 1 is characterized in that insulation material layer (5) is preferably alumina silicate fibre.
3, electric hot tray according to claim 1 is characterized in that insulation material layer (4) forms with aluminum phosphate and carborundum allotment.
