Abstract
The utility model discloses a vacuum heat-insulation electric-heating plate. An electric-heating pipe is embedded in a metal plate, the back side of the metal plate is provided with a glass cover connected a sealing form through metal connecting rings which are respectively embedded and arranged on the back side of the metal plate and the edge opening of the glass cover, the glass cover is penetrated with an electrode, a leading electrode of the electric heating pipe is connected with the electrode and a cavity between the metal plate and the glass cover is a vacuum cavity. The heat below the electric heating plate is isolated by the vacuum so as to prevent the heat loss and improve the utilization rate. In addition, because of the vacuum insulation at the bottom of the glass cover, the poor heat conduction property of the glass, low temperature, and direct contact with the bottom casing of a cooker, the height of the cooker can be reduced.
Description
Technical field
The utility model relates to electrothermal device, particularly a kind of electric heat-generating disc.
Background technology
Be widely applied to electric heat-generating disc in the domestic electric heating cooker, aluminium electric hot tray particularly, existing electric hot tray is that electrothermal tube is embedded in the mould, uses the aluminium die cast.Because electric hot tray has only top and cooker transmission of heat by contact, but following same heating, following heat distributes by the convection current of thermal radiation and air, causes heat utilization efficiency low.In addition, the drain pan of cooker can not be near excessively with electric hot tray, and pot waits in the utensil on as table, makes the height of cooker to reduce, and has limited the application of electric hot tray.
Summary of the invention
The utility model purpose is to provide a kind of electric heat-generating disc of single face heating, to improve its efficiency of utilization.
Scheme of the present utility model is: a kind of vacuum heat-insulation electric heating dish, in metal dish, be embedded with electrothermal tube, the back side of metal dish is provided with cloche, be tightly connected by the metal connecting ring that is embedded in the metal dish back side and cloche bead respectively, be equipped with electrode on the cloche, the extraction electrode of electrothermal tube is connected with electrode, and the cavity between metal dish and cloche is a vacuum chamber.
The utility model has the advantages that: because the cavity between metal dish and cloche is a vacuum chamber, the heat below the metal dish has prevented loss by vacuum insulating, has improved heat utilization efficiency.In addition, the cloche of bottom is owing to vacuum heat-insulation, and it is poor to add the upper glass conductivity of heat, and temperature is low can directly to be contacted with the cooker drain pan, can reduce the height of cooker, the convenient use.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Accompanying drawing is a structure cutaway view of the present utility model.
Among the figure, 1 metal dish, 2 electrothermal tubes, 3 metal connecting rings, 4 electrodes, 5 cloches, 6 mouths of bleeding.
Embodiment
The structure of the vacuum heat-insulation electric heating dish of embodiment as shown in drawings, be in metal dish 1, to be embedded with electrothermal tube 2, the back side of metal dish 1 is provided with cloche 5, be connected by metal connecting ring 3 welded seals that are embedded in metal dish 1 back side and cloche 5 beads respectively in advance, be equipped with electrode 4 on the cloche 5 in advance, 5 frit seals of electrode 4 and cloche, the extraction electrode of electrothermal tube 1 is connected with electrode 4, and the cavity that metal dish 1 and cloche are 5 vacuumizes.
During work, the heat below the metal dish has prevented loss by vacuum insulating, has improved heat utilization efficiency.In addition, the cloche of bottom is owing to vacuum heat-insulation, and it is poor to add the upper glass conductivity of heat, and temperature is low can directly to be contacted with the cooker drain pan, can reduce the height of cooker, the convenient use.
