Embodiment Construction

[0018] figure 1 The schematic perspective view of FIG. shows an electric cooking vessel 10, which is preferably plastic and has a substantially cylindrical outer surface 14 at least in the bottom region 12. A handle 16 is used to handle the cooking vessel 10 and can be designed in various ways and fastened to the outer circumference, for example as shown. Also visible on the bottom region 12 of the cooker 10 is a shroud 20 which is placed on the outer circumference 14 of the cooker and is secured by means of a base 36 fastened to the cooker. The vessel base 36 thus forms part of the foot of the cooking vessel 10 in the exemplary embodiment shown. The lower edge 22 of the shroud 20 is thus held by the vessel floor 36 . The cooking vessel 10 rests on the vessel base 36 in the state of being placed on the rack. The outer surface of the shroud 20 is flush with the outer peripheral surface of the cooking vessel 10 in the illustrated embodiment, which is also combined with figu...

Abstract

The present invention relates to an electric-heating cooker which includes a plastic cooking ware (10), a ware baseboard and an outer covering ring (20), the ware baseboard comprises an electric-heating mechanism (30) and is held in the bottom area (12) at the internal circumferential surface of the cooking ware shape-adaptedly or transferring-force-adaptedly by an annular sealing piece (32), and the covering ring is arranged in the bottom area (12) at the outer circumferential surface of the cooking ware. The invention prescribes that the covering ring is pasted on the outer circumferential surface (14) of the cooking ware with one part of the internal circumferential surface and is connected with the outer circumferential surface (14) transferring-force-adaptedly without clearance when the energizing-heating mechanism (30) works. The invention also relates to an installing method of the corresponding cooker.

Description

technical field [0001] The invention relates to an electric heating cooker. Background technique [0002] In electric cooking utensils, especially plastic electric kettles, the plastic kettle expands to a certain extent due to the high coefficient of thermal expansion of the plastic when the heating mechanism is working. When the heating element is fixed in the cylindrical inner wall of the plastic jug, there is a risk that the connection between the heating element and the inner wall of the plastic jug will loosen due to thermal expansion when the heating element is in operation. In this case, the sealing of the kettle cavity can no longer be reliably ensured. Therefore, in known electric cooking appliances, the heating assembly is fixed in the cooking vessel by means of additional means, for example by means of expansion rings or the like. [0003] WO01 / 93732A1 discloses an electric kettle, wherein the heating element is fixed on the cylindrical inner wall of the kettle ...
