摘要:
A radiant cooking unit comprises a heat insulating material forming a heating element carrier to which electrical heating elements are secured. It is surrounded by a ring-shaped bordering element of a heat insulating material relatively rigid in design. Both moldings are molded together by a ram. In another aspect the outer ring is divided into several ring sectors. A hoop of flat material clasps this ring-shaped bordering element on all sides, the latter being configured as a single-turn induction coil for a pot sensing system and simultaneously clamping the unit together.

An apparatus (1) for compensating the maladjustment of a power control means (2) by changes to the ambient temperature operates at least on a partial path against the flat spring (31) of a correcting device (30), after which at least part of the ambient temperature sensor (20) of the apparatus (1) is fixed against further deflection by a stop (34), so that the actual values of the power setting correspond to the set desired values substantially independently of the ambient temperature. For the correction spring (31) or for the stop (34) it is not necessary to provide a separate component, if use is made for the same of the already present twisting preventer (28) or a carrier (18).

The lower cover plate of an electric hotplate is fixed to the hotplate body by a resilient fixing structure provided on the cover plate, engaging with gripping edges on the outer face of a downwardly directed, central cast pin. The fixing structure can be defined by radial or flap-like, inwardly-directed portions of the cover plate and additionally can have portions engaging on the lower face of the pin and which are firmly held by the final screwing down of the electric hotplate.
摘要:
A control instrument is provided for electric cooker plates. The instrument comprises an adjustable quantizing power control instrument having an expansion element with an electric heating element and a time switch member for increasing the power adjusted on the power control instrument for a period in the initial cooking phase. The time switch member comprises an electronic counter timing member and at least one divider which, via an electronic switch element, reduces the power supplied to the heating element in a predetermined division ratio.

Power controls for electrically heated appliances, such as cooking plates. An energy control element in the power controls with a bimetallic member which has a control heating element and a contactor which influences the control heating element therein.
摘要:
A heat insulating molded body made of inorganic material and inorganic reinforcement fibers is disclosed, as well as a process for producing the same and its use. The molded body is characterized by the following composition: (a) 30-70 wt. % blown vermiculite; (b) 15-40 wt. % inorganic binder; (c) 0-20 wt. % infrared opacifier; (d) 15-50 wt. % microporous material; (e) 0.5-8 wt. % reinforcement fibers which contain maximum 2 wt. % B2O3 and at most 2% alkalimetal oxide, based on the weight of the reinforcing fibers.
摘要:
For an electric hotplate is provided an assembly arrangement using a bearing ring, which forms a continuous, one-piece, smooth-surface top extending from the outermost circumferential area of the hotplate body located close to the cooking surface to its outer circumference or to the mounting plate and has a relatively shallow collecting depression for liquid which has flowed over between an inner and an outer ring profile. With the hotplate or bearing ring can be associated at least one shield and at least one locking and/or centering device for position fixing purposes, so that there is a simple and positionally accurate assembly. The bearing ring can also be stop-limited towards the bottom against deformation.
摘要:
In an electric switching device (1), particularly constructed as a temperature regulator, the resilient switching arm (14) controlled by a hydraulic expansion cell (12) for operating a snap switch (5) is fixed by means of positively engaging snap connections (32) to plate-like support parts (20) of a sheet metal support body (3) of a body (2), the support parts (20) on either side of the switching arm (14) being at right angles to joint axis (25) of arm (14) as lateral bends to a base plate (30) of support body (3) and receive between them an end portion of an insulator (4) carrying the switch (5). This leads to an extremely favourable taking up of forces, so that the support body (3) can be made from extremely thin sheet metal as a relatively elastic component. It also leads to a very simple assembly of the switching arm (14).
摘要:
In a cooker plate (1) connection of the particular electric hotplate (3) a window opening (19) is provided as an assembly opening in a holding part (5) substantially completely covering the same on the underside, through which can be passed a connecting piece (21) for the electrically conducting connection to the connecting members (15) of hotplate (3). This window opening (19) can be substantially completely closed with a closure (20), the latter being constructed in one piece with a ceramic insulator (22) of connecting piece (21) or can be formed by a separate component made from sheet metal or the like. This leads to a very reliable and effective closure of the cooker plate (1), also on the underside thereof.
