Abstract

The utility model discloses an electric heating disc, which comprises a high-temperature resistant insulating-material disc body and a heating wire. The heating wire is coiled and inlaid on the surface of the high-temperature resistant insulating-material disc body. As the heating wire is coiled and inlaid on the surface of the high-temperature resistant insulating-material disc body, most of the surface area of the electric heating disc is embedded in a high-temperature resistant insulating material so as to play a role of preventing oxidation and ensuring long life span. In addition, the electric heating disc has the advantages of high thermal efficiency, good application effect, simple structure and low production cost.

Description

Electric hot tray

Technical field

The utility model relates to a kind of heating appliances, particularly a kind of electric hot tray.

Background technology

Electrothermal furnace in uses such as family, laboratory, hospitals mainly contains two kinds at present, and a kind of is exposed heating wire formula electric furnace, and another kind is the electric furnace that adopts closed electric heating dish.Wherein, the heating wire of exposed heating wire formula electric furnace exposes very easily oxidation in air, influences the useful life of product, uses and does not lean on; Though and closed electric heating dish can overcome the above-mentioned shortcoming of exposed heating wire formula electric furnace, the heat efficiency is higher, useful life is longer, but, the complex structure of this kind electric furnace, its structure must comprise the cast iron chassis, offers the heating wire groove on the cast iron chassis, the insulated conductive layer of the surface coverage of heating wire groove, heating wire is installed on the insulated conductive layer, and an insulated thermal insulating layer is arranged on heating wire again, said structure cost of raw material height, making complexity.

Summary of the invention

In order to solve the above problems, the purpose of this utility model is to provide a kind of simple in structure, with low cost, electric hot tray that result of use is good.

The technical scheme that the invention for solving the technical problem adopted is:

Electric hot tray comprises high-temperature insulation material disk body and heating wire, and the heating wire coiling is embedded in the surface of high-temperature insulation material disk body.

Further, the upper surface of described heating wire and high-temperature insulation material disk body upper surface maintain an equal level.

Wherein, the upper surface of described high-temperature insulation material disk body can also be provided with a high-temperature insulation material top layer.

In addition, as another kind of execution mode, the outer rim of described high-temperature insulation material disk body has a constraint circle.

As preferred implementation, described heating wire is a flat, and it vertically coils the surface that is embedded in the high-temperature insulation material disk body.

The beneficial effects of the utility model are: because the coiling of the heating wire of this electric hot tray is embedded in the surface of high-temperature insulation material disk body, its most surfaces is long-pending to be embedded in the high-temperature insulation material, played the effect of anti-oxidation, long service life, while heat efficiency height, result of use is good, and simple in structure, low production cost.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is a sectional structure schematic diagram of the present utility model;

Fig. 3 is the I portion enlarged drawing of Fig. 2;

Fig. 4 is the structural representation of the another kind of execution mode of the utility model.

Embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, electric hot tray of the present utility model comprises high-temperature insulation material disk body 1 and heating wire 2, and heating wire 2 coilings are embedded in the surface of high-temperature insulation material disk body 1.

As preferred implementation, the upper surface of described heating wire 2 and high-temperature insulation material disk body 1 upper surface maintain an equal level, the interior lateral surface of heating wire 2, lower surface are coated by high-temperature insulation material, can play the effect of anti-oxidation, and this damascene structures is simple, easy to make, when producing, earlier heating wire is embedded in the high-temperature insulation material of unhardened moulding, again it is carried out cure process, thereby obtain the electric hot tray that heating wire 2 is embedded in high-temperature insulation material disk body 1 surface.

Further, described heating wire 2 is a flat, its vertically coiling be embedded in surface of high-temperature insulation material disk body 1, the length of such heating wire of inlaying is longer, the area that exposes still less, result of use is good, and makes simple.Certainly, this heating wire also can be other shapes such as rounded body, triangle body.

In addition, the outer rim of described high-temperature insulation material disk body 1 can also be provided with a constraint circle 3.

With reference to Fig. 4, as another kind of execution mode, the upper surface of described high-temperature insulation material disk body 1 can also be provided with a high-temperature insulation material top layer 4, under specific operating position, can directly contact like this, avoid the generation of security incident with other metal material.

In addition, electric hot tray of the present utility model can be placed heat carriers such as crystallite panel and metal heat-conducting plate on this electric hot tray when producing and use, to be fit to the use of different situations.

Certainly, the invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model.
