The ceramic liner electric cooker has good heat build-up and heat-insulating property, when cooking food, and the better effects if that cooks food, using ceramic material to make inner bag can economize on resources, and more environmental protection, much cleaner.But, because ceramic liner easy deformation when sintering is made, cause dimensional tolerance bigger, so the internal diameter of the heating jacket of ceramic liner electric cooker in the market is more a lot of greatly than the external diameter of ceramic liner, can insert wherein to guarantee ceramic liner, certainly will between heating jacket and ceramic liner, be formed with certain interval like this, during use, the heat that heating jacket produced must just can pass to ceramic liner by the conduction of air, therefore, thermal loss is bigger, the efficiency of heating surface is lower, and the volume of heating jacket and whole electric cooker is also relatively large.
Summary of the invention
The utility model purpose is: the three-dimensional directly conduction of a kind of ceramic liner electric cooker heater is provided, the heating jacket of this device contacts with ceramic liner, the heat of heating jacket is directly passed to ceramic liner, not only reduce thermal loss, improved the efficiency of heating surface, and the overall volume of heating jacket and electric cooker can be dwindled relatively, thereby has also reduced material consumption, reduced production cost.
The technical solution of the utility model is: the three-dimensional directly conduction of a kind of ceramic liner electric cooker heater, comprise the heating plate that is positioned at the bottom, the top of heating plate is equipped with can be for the heating jacket with elastic telescopic function of ceramic liner placement, the outer wall of described ceramic liner directly contacts with the inwall of heating jacket, and the heat of heating jacket is directly passed to ceramic liner; Described heating plate is curved, and the bull nose of the filleted corner of its bottom surface and ceramic liner bottom is coincide, and the upper edge of heating plate can be coated to the bottom of the sidewall of ceramic liner; Described heating jacket is back taper, and its tapering is identical with the tapering of ceramic liner sidewall.
The further technical scheme of the utility model is: the three-dimensional directly conduction of a kind of ceramic liner electric cooker heater, comprise the heating plate that is positioned at the bottom, the top of described heating plate is equipped with can be for the heating jacket with elastic telescopic function of ceramic liner placement, and the outer wall of heating jacket is fixed with Electrothermal ring; Described heating plate is curved, and the bull nose of the filleted corner of its bottom surface and ceramic liner bottom is coincide, and the upper edge of heating plate can be coated to the bottom of the sidewall of ceramic liner; Described heating jacket is back taper, and its tapering is identical with the tapering of ceramic liner sidewall; The upper edge of described heating plate is provided with a circle flanging, and the lower edge of heating jacket is provided with circle opening buckling groove inwardly, and buckling groove is fastened on the flanging, and heating jacket and heating plate are connected and fixed; Described heating jacket is provided with the longitudinal extension seam, the overlapping overlap joint of side of longitudinal extension seam both sides.
The more detailed technical scheme of the utility model is: the three-dimensional directly conduction of a kind of ceramic liner electric cooker heater, comprise the heating plate that is positioned at the bottom, the top of described heating plate is equipped with can be for the heating jacket with elastic telescopic function of ceramic liner placement, and the outer wall of heating jacket is fixed with Electrothermal ring; Described heating plate is curved, and the bull nose of the filleted corner of its bottom surface and ceramic liner bottom is coincide, and the upper edge of heating plate can be coated to the bottom of the sidewall of ceramic liner; Described heating jacket is back taper, and its tapering is identical with the tapering of ceramic liner sidewall; The upper edge of described heating plate is provided with a circle flanging, and the lower edge of heating jacket is provided with circle opening buckling groove inwardly, and buckling groove is fastened on the flanging, and heating jacket and heating plate are connected and fixed; Described heating jacket is provided with the longitudinal extension seam, the overlapping overlap joint of side of longitudinal extension seam both sides; The outer wall of described heating jacket is equipped with Electrothermal ring, and Electrothermal ring is provided with fracture, and the two ends of fracture is connected with back-moving spring; The lateral wall of described heating jacket is provided with spring band; The lateral wall of described heating jacket is provided with a circle flange, and spring band rests on the flange.
The utility model advantage is:
1. the utility model heating jacket contacts with ceramic liner, and the heat of heating jacket is directly passed to ceramic liner, not only reduced thermal loss, improved the efficiency of heating surface, and the overall volume of heating jacket and electric cooker can be dwindled relatively.
2. because ceramic liner easy deformation when sintering is made, cause dimensional tolerance bigger, therefore the utility model is provided with the longitudinal extension seam on heating jacket, make the internal diameter of heating jacket can adjust variation within the specific limits, thereby satisfy the requirement of placing ceramic liner, improved the utilization rate of ceramic liner.
