Description

The electric heating thermal insulation stove

Technical field

The utility model relates to the electric heating thermal insulation stove for food is incubated in a kind of hotel, restaurant.

Background technology

At present, in many hotels, restaurant, all can use the electric heating thermal insulation stove to be incubated food, so that client's food when Sheng takes food is difficult for turning cold, the electric heating thermal insulation stove of prior art generally as shown in Figure 1, it comprises heating inner liner 01, the downside of heating inner liner 01 is provided with the electrothermal tube 02 for heating inner liner 01 is heated, electrothermal tube 02 is connected with power supply, electrothermal tube 02 is distributed on the bottom surface of heating inner liner 01, be coated with thermal insulation layer 03 on electrothermal tube 02, after this electric heating thermal insulation stove energising, electrothermal tube 02 heating also is delivered to heating inner liner 01 by heat.

This electric heating thermal insulation stove is owing to being heated by electrothermal tube 02, and electrothermal tube 02 is very little with the contact area of heating inner liner 01, make the thermal energy transfer efficiency between electrothermal tube 02 and heating inner liner 01 lower, the heat energy that makes electrothermal tube 02 produce is depleted by air greatly, make this electric heating thermal insulation stove need larger power just can reach heat insulation effect, also just need to expend more electric energy.

The utility model content

Technical problem to be solved in the utility model is, provides the thermal energy transfer efficiency between a kind of heat generating components and heating inner liner higher electric heating thermal insulation stove, and this electric heating thermal insulation stove power is lower, energy consumption is less.

For solving the problems of the technologies described above, the electric heating thermal insulation stove that the utility model provides, it comprises heating inner liner, the heat generating components for heating inner liner is heated, and is coated with thermal insulation layer on heat generating components, described heat generating components is the electric heating film be connected with power supply.

After adopting above structure, the utility model compared with prior art, has advantages of following:

The utility model is used electric heating film as heat generating components, the bottom surface of electric heating film and heating inner liner fits, make the contact area between electric heating film and heating inner liner larger, after the electric heating film heating power, thermal energy transfer efficiency between electric heating film and heating inner liner is higher, the heat energy that makes electric heating film produce can be delivered to heating inner liner fast, the heat energy that makes electric heating film be depleted by air is less, make this electric heating thermal insulation stove can realize heat insulation effect with lower power, the electric energy that also just makes this electric heating thermal insulation stove expend is less, comparatively energy-conservation.

As preferably, the thermo electric material in described electric heating film is Aludirome, nichrome, constantan wire or carbon fiber.

As preferably, the electrically insulating material of described electric heating film is high-temperature-resistant flexible thin slice or rigid sheet.

As preferably, described electric heating film and heating inner liner are bonding by the heat-resistant adhesive water; Make between electric heating film and heating inner liner laminating comparatively tight, guarantee that a surface of electric heating film contacts with heating inner liner integral body, contact area is larger.

As preferably, described thermal insulation layer is asbestos layer; The effect of heat insulation of asbestos layer is better.

Fig. 2 is the structural representation (shell of electric heating thermal insulation stove is not drawn) of the utility model electric heating thermal insulation stove;

Fig. 3 is the use state diagram (shell of electric heating thermal insulation stove is not drawn) of the utility model electric heating thermal insulation stove.

In prior art, 01, heating inner liner; 02, electrothermal tube; 03, thermal insulation layer.

In the utility model, 1, heating inner liner; 101, bottom surface; 2, electric heating film; 3, asbestos layer; 4, pressing plate; 5, water; 6, food tray.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

As shown in Figure 2, the utility model electric heating thermal insulation stove comprises the heating inner liner 1 of stainless steel, the downside of heating inner liner 1 is provided with electric heating film 2, electric heating film 2 is connected with power supply, the bottom surface of the upper surface of electric heating film 2 and heating inner liner 1 is bonding by the heat-resistant adhesive water, be coated with asbestos layer 3 on the lower surface of electric heating film 2, the downside of heating inner liner 1 also is provided with for making the fixing pressing plate 4 of asbestos layer 3 and electric heating film 2

Thermo electric material in described electric heating film 2 is Aludirome, nichrome, constantan wire or carbon fiber, and certainly, described electric heating film 2 also can be selected other known materials, and it is all within protection domain of the present utility model.

With reference to Fig. 3, when this electric heating thermal insulation stove uses, put into a certain amount of water 5 in heating inner liner 1, then the food tray of food container 6 is shelved on heating inner liner 1, switches on power, make electric heating film 2 start heating, the heat of electric heating film 2 transmits feedwater 5 by heating inner liner 1, make water 5 boilings produce steam, steam transfers heat to food tray 6, makes the food be contained in food tray 6 to be incubated.

Certainly, heating inner liner 1 also can be selected other known materials, and it is all within protection domain of the present utility model.

Here the electrically insulating material of said electric heating film 2 can be high-temperature-resistant flexible thin slice or rigid sheet, and flexible flake can be made by silica gel, PET polyester film, polyimide etc., and rigid sheet can be made by pottery etc.

Miscellaneous part in the electric heating thermal insulation stove, as temperature controller, switch etc. is known technology, do not elaborate here.
