Abstract
The utility model relates to an electric heater for an electric cooker. Both sides of an electric heating body are respectively provided with insulating layers which are back positioned on a bottom bearing plate of a heater. The utility model is characterized in that an upper tray is also arranged on the bottom bearing plate which is positioned above the electric heating body; the wall height L of the tray is between 10 mm and the height of an inner liner. The heat-transfer efficiency is raised, the heat transfer is uniform, and the inner liner can not be broken. Thus, the utility model can be used for rice cookers, tile cookers, chafing dishes, etc., wherein, the inner liners of which are made up of non-metallic materials which are easy to be broken, such as ceramic, glass, etc.
Description
The utility model relates to a kind of electric heating device of electric food warmer.
The electric heating device that two kinds of electric food warmers are arranged in the market, a kind of is heating tape, and its chuck is outside aluminium lining courage, and its advantage is that heating is even, can not make gallbladder break in it, but its thermal efficiency is low; Another kind is an electrothermal tube cast aluminium heating board, though improved the thermal efficiency, it is inhomogeneous because of conducting heat, the medium temperature height, and the next door temperature is low, makes gallbladder break in it easily.
The purpose of this utility model provides a kind of conduct heat evenly, can not make gallbladder break and the high electric food warmer electro-heat equipment of the thermal efficiency in it.
In order to achieve the above object, the utility model is achieved in that the both sides of electric heating body are respectively equipped with insulating barrier and are placed on the backing board of heating element; It is characterized in that: be positioned on the backing board heater above also be provided with a top tray, the height of the high 10MM≤L of the wall of pallet≤inner bag.The wall of pallet and 60 °≤α of the angle of bottom surface≤165 °.There is a radian bottom surface of pallet, and the radius of its radian is 0≤R≤1000MM.The bottom surface of pallet is provided with the boss more than 3 at least.
The utility model compared with prior art has following advantage:
1, heat transfer efficiency has improved;
2, owing to conduct heat evenly, its inner bag can not break, and therefore can be widely used in pot for cooking rice, watt pot and chafing dish etc. that inner bag is made by the nonmetallic materials of easy hot tearing such as pottery, glass.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, be respectively equipped with insulating barrier (2) on the both sides of electric heating body (3) and reach insulating barrier (4) down, place then on the backing board (6) of heating element; On the shell of backing board (6), also be provided with the binding post (5) of a heater (3); Upward also be provided with a top tray (1) above heater (3) at backing board (6), in the utility model, the high L of wall of pallet (1) is 32MM, and the wall of pallet (1) and the angle α of bottom surface are 90 °, and the radius R of the bottom surface radian of pallet (1) is OMM.Be provided with 3 boss (7) in the bottom surface of pallet (1),, boss (7) (as being used for ceramic electric cooker etc.) also can be set in the bottom surface of pallet (1) according to different application.
Claims (4)
1, a kind of electric heating device of electric food warmer, the both sides of electric heating body are respectively equipped with insulating barrier and are placed on the backing board of heating element; It is characterized in that: the top that is positioned at heater (3) on backing board (6) also is provided with a top tray (7), the height of the high 10MM≤L of the wall≤inner bag of pallet (1).
2, the electric heating device of electric food warmer according to claim 1 is characterized in that: the 60 °≤α of angle of the wall of pallet (1) and bottom surface≤165 °.
3, the electric heating device of electric food warmer according to claim 1 is characterized in that: there is a radian bottom surface of pallet (1), and the radius of its radian is 0≤R≤1000MM.
