Abstract
The utility model relates to a domestic electric heating cooker, which is an electric heating lunch box. The purpose is realized by fixing to the bottom of a stainless steel lunch box by a U-shaped tubular electrothermal element and an N-shaped aluminum alloy heat conducting plate. A bounce temperature limiter is also arranged in the center of the bottom of the lunch box simultaneously. The temperature limiter and the lunch box are isolated by an isinglass sheet. One end of the lunch box is provided with a flexible handle. The lunch box can be used for boiling, stewing and personal chafing dishes, etc. The electric heating lunch box has the advantages of small size, convenience, and safety.
Description
The utility model relates to household appliance technical field, particularly the domestic electric heating cooker.
The domestic electric heating cooker resembles electric cup, electric cooker etc. and is accepted extensively and use by people already, and its advantage is on record.Adopt naked formula heating wire directly to heat but electric cup more, do not have temperature regulating device in the use, the easy cause thermal damage of crossing, security performance is low; Domestic Electric Cooker adopts cloud nurse heating plate to heat more, and insulation and temperature-limiting device are housed, and use safety, convenient, but its volume ratio is bigger, is suitable for family and uses, and is not easy to unmarried person's use or travelling and carries; Utility model 90218840 disclosed a kind of functional electric heating pot products, its heating adopts the composite electrothermal tube structure, promptly at tubular electrothermal element overcoat one aluminum pipe, the aluminum pipe upper compressive becomes almost plane, on add aluminium matter soaking plate, be fixed in a pot body by a steel compression plate, have dependable performance, thermal efficiency height, homogeneous heating, characteristics such as quick heating, but its complex structure, overall weight is big, and using also has inconvenience.
The purpose of this utility model is, design a kind of volume little, safely, be easy to carry, family, the unmarried or all spendable electric heating mess tin of travelling outdoors are to remedy the deficiency of above electric-heating cooking utensil.
The technical solution of the utility model is achieved in that selects for use stainless steel lunch box and electric heating device to be fixed into one.Said electric heating device is to adopt the tubular electrothermal element, be preferably carbon steel, it curved " U " type, inclusion is in the groove of " π " type aluminium alloy heat-conducting plate, be welded in the bolt of lunch box bottom by point, " π " type aluminium alloy heat-conducting plate is fixed on bottom the lunch box.The heat that electrical heating element produced like this is evenly distributed in the lunch box bottom, to avoid hot-spot through the conduction of aluminium alloy heat-conducting plate.In the lunch box bottom center beat type temperature limiter is housed also, isolated between temperature limiter and the lunch box by cloud nurse sheet, fixed by the aluminium alloy heat-conducting plate.Electrical heating element, temperature limiter and aluminium alloy heat-conducting plate are sealed by drain pan, and lunch box one end is furnished with flexible handle.
The power of electrical heating element can be selected between the 400--800W, selects according to demand.Under normal circumstances, temperature limiter is closure state, circuit clear.During use, at first place heated food in lunch box, connect 220V, 50HZ power supply then, electrical heating element is started working, and finishes using and cuts off the electricity supply.If overheated dried pot phenomenon in use occurred, when the lunch box bottom temp rose to 160 ℃, heat can reach temperature limiter through the cloud nurse sheet with good heat conductive performance, and temperature limiter can be cut off the electricity supply automatically, stops heating, guarantees safety; When temperature was reduced to 80 ℃, temperature limiter automatic restoring circuit, heater element can restart work again.
Below in conjunction with accompanying drawing the utility model is explained in detail.
Figure one: the front view of electric heating mess tin
Figure two: the left view of electric heating mess tin
The title of number in the figure: (1) stainless steel lunch box, (2) tubular electrothermal element,
(3) aluminium alloy heat-conducting plate, (4) bolt, (5) beat type temperature limiter,
(6) cloud nurse sheet, (7) drain pan, (8) flexible handle,
(9) power line, (10) terminal plate.
Tubular electrothermal element (2) is curved " U " type, inclusion is in the groove of " π " type aluminium alloy heat-conducting plate (3), be welded in the set bolt (4) of stainless steel lunch box (1) bottom by point, to be somebody's turn to do " π " type aluminium alloy guide plate (3) and be fixed on the bottom of lunch box (1), beat type temperature limiter (5) is contained in the lunch box bottom center, isolated between temperature limiter and the lunch box by cloud nurse sheet (6), fixed by the aluminium alloy heat-conducting plate, heating (2), temperature limiter (5) and aluminium alloy heat-conducting plate are sealed by drain pan (7).
The utility model possess boil, boil in a covered pot over a slow fire, the function such as individual chafing dish, in routine use, also have simple in structure, volume is little, be convenient for carrying, the advantage of safety, is particularly suitable for the unmarried use in dormitory.
Claims (1)
1, a kind of pot of body and electric heating device all-in-one-piece electric heating mess tin, it is characterized in that: tubular electrothermal element (2) curves " U " type, inclusion is in the groove of " π " type aluminium alloy heat-conducting plate (3), and this heat-conducting plate is fixed on the lunch box bottom by the bolt (4) that point is welded in stainless steel lunch box (1) bottom; In the lunch box bottom center beat type temperature limiter (5) is housed also, isolated between temperature limiter and the lunch box by cloud nurse sheet (6), to be fixed by the aluminium alloy heat-conducting plate, lunch box one end is furnished with flexible handle (8).
