Abstract
The utility model discloses a heating plate of electrothermal furnaces, which comprises a plate body, electric heating wires, a layer of magnesium oxide power, a bolt and a tray, wherein the tray is internally provided with an insulating layer of lightweight calcium silicate, the layer of magnesium oxide power which is disposed inside a prefabricated groove arranged on the insulating layer of lightweight calcium silicate is closely attached to the lower bottom face of the plate body, a caulking groove for embedding the electric heating wires is arranged on the layer of magnesium oxide power, the electric heating wires are installed inside the caulking groove, a projection is arranged around the middle portion of the bolt, and the tray is limited by the projection arranged on the bolt. In the heating plate, as the insulating layer of lightweight calcium silicate with perfect performance of heat preservation and heat resistance is arranged between the tray and the layer of magnesium oxide power, heat loss of a non-working surface at the lower portion of the heating plate is largely reduced, thereby energy resource can be effectively utilized, the lower bottom face of the plate body is not equipped with a rib groove structure, instead the caulking groove for embedding the electric heating wires is arranged on the layer of magnesium oxide power, thereby being convenient for machining and installation, and reducing costs of raw materials and machining.
Description
Technical field
The utility model relates to a kind of electrothermal furnace heat-generating disc.
Background technology
Because have characteristics such as quick, health, electrothermal furnace has become one of first-selected cooking apparatus of people gradually.Heat-generating disc is as the main parts size of electrothermal furnace, as Fig. 1, the general muscle groove that all casts out planar spiral at disk body 1 back side of its working face, in the muscle groove, be prefabricated into corresponding groove with it again with magnesium oxide powder, then heating wire 2 is embedded wherein, with the oxygen magnesium dust its compacting is fixed again.There is a shortcoming in this kind structure, that is exactly that to have only its top be working face to heat-generating disc, the bottom is a non-working surface, and also coated by the quite high magnesium oxide powder of thermal conductivity as the heating wire bottom of stone or metal plate for standing a stove on as a precaution against fire thermal source, heat can scatter and disappear downwards with the form of radiation so stone or metal plate for standing a stove on as a precaution against fire has greatly when work, so, electric furnace not only can not make full use of its energy when work, but also the peripheral structure spare of its underpart has been proposed comparatively harsh heat-resisting requirement, cause the production cost of complete machine to improve.
The utility model content
To be solved in the utility model to be exactly that heat-generating disc bottom non-working surface heat scatters and disappears big, peripheral structure heat-resisting requirements in bottom is harsh and cause the high technical problem of production cost, provides a kind of bottom non-working surface heat lost little and electrothermal furnace heat-generating disc that production cost is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of electrothermal furnace heat-generating disc, comprise that lower central is provided with the disk body of screwed hole, heating wire, the magnesium oxide powder layer, screw rod is housed on the screwed hole, it is characterized in that: it also comprises a pallet, be provided with one deck lightweight calcium silicates separation layer in the pallet, described magnesium oxide powder layer is arranged in the prefabricated groove on the lightweight calcium silicates separation layer, and be close to and the disk body bottom surface, the magnesium oxide powder layer is provided with the caulking groove that embeds heating wire, heating wire is installed in the described caulking groove, and described screw rod middle part is equipped with a protuberance, and described pallet is spacing by the protuberance on the screw rod.
Improved, described protuberance is provided with an elastic washer, and elastic washer leans on the tray bottom side, strengthens the connective stability of pallet.
Preferably, described protuberance is the active nut that is installed on the screw rod, is convenient to install and regulate.
Improved, described disk body is provided with the lug eaves corresponding with pallet top eaves, guarantees the structural stability of product.
Improved, described pallet top eaves is connected with disk body.Can adopt welding, screwing or other version to connect, further strengthen the firm and stable of structure.
Preferably, described pallet shaft section is flat U type.
The utility model is owing to adopt technique scheme, at pallet and magnesium oxide powder interlayer one deck insulation, the good lightweight calcium silicates of heat resistance separation layer are set, thereby greatly reduce scattering and disappearing of heat-generating disc bottom non-working surface heat, more effectively utilize the energy, and the disk body lower surface is not provided with muscle groove structure, but on the magnesium oxide powder layer, establish the caulking groove that embeds heating wire, also be convenient to processing and reduction raw material and processing cost are installed.
