Publication number: 20030010769Abstract: According to an embodiment of the invention, an electric radiant heater (11, 111) is provided having an active sensor (21, 121) for detecting the position of a cooking vessel on a glass ceramic plate over the radiant heater (11, 111). The sensor (21, 121) is made from electrically conductive material and is part of an inductive resonant circuit of a control operating by resonant circuit detuning. It also covers a heating zone (17, 117) of the radiant heater (11, 111). According to the invention, the sensor (21, 121) runs substantially linearly and, unlike conventional sensor coils, has a loopless construction. It is e.g. possible to stretch a wire (121) or also to use the tube (21) of a rod regulator.Type: ApplicationFiled: July 9, 2002Publication date: January 16, 2003Inventors: Eugen Wilde, Erich John, Wilfried Schilling

Patent number: 6483084Abstract: According to an exemplary embodiment of the invention a radiant heater (11) for a glass ceramic cooking area (25) is created. The radiant heater comprises a carrier shell (12) carrying a flat insulator (14), on which is placed a heating means (16). A thermal relay (18) projects with its tube-like sensor (19) into the central area of the radiant heater (11) and the sensor can rest on an elevation (23) of the insulator (14). By means of a holder (45) the sensor (19) can be fixed to the carrier shell (12). The holder does not project over the underside of the carrier shell (12). In one embodiment the holder with barb-like ends reaches into an opening in the carrier shell and is fixed to locking edges of the carrier shell.Type: GrantFiled: September 7, 2001Date of Patent: November 19, 2002Assignee: E.G.O.

Patent number: 6448539Abstract: On the one hand is provided an electric heating element (15, 31) consisting of a semiconducting ceramic (28, 32) as well as a method for its production. The semiconducting ceramic material may be porous or foamed to thus contain pores (29, 34) open outwardly. The pores are attainable by admixing filler bodies, which dissolve during sintering, to the starting material or by impreganting a textile substrate material (36) with a ceramic material. Due to the porosity of the heating element (15, 31) an increased radiant surface area is attained. On the other hand is provided an electric heating element (115, 132, 145, 150, 158, 160, 162) as well as a method for its production which consists of semiconducting ceramic and comprises a negative temperature coefficient of the electrical resistance. The temperature coefficient is negative throughout over the full operating temperature range. The material suitable for the heating element (115, 132, 145, 150, 158, 160, 162) is doped silicon carbide or TiN.Type: GrantFiled: February 1, 2001Date of Patent: September 10, 2002Assignee: E.G.O.

Patent number: 6229119Abstract: A casing (11) of a thermostat (12), which is to be fixed to the rim (17) of a reception container (16) for a heating device, is substantially inserted in a recess (23) of the rim (17). The recess (23) is open to the outer edge of the rim (17) and has two lateral boundaries (24). In the fitted state the casing (11) forms a mechanical connection between the lateral boundaries (24) and closes the transmission of forces in the course of the rim (17) and in particular clamps together the rim in the circumferential direction. The fastening of the casing (11) and the bracing takes place by means of at least partly bent round and/or bend roundable fastening tongues (25) and/or clamping tongues (27), preferably emanating from the lateral boundaries (24). The invention inter alia leads to a positionally reliable positioning of the thermostat (12) on the reception container (16).Type: GrantFiled: October 12, 1999Date of Patent: May 8, 2001Assignee: E.G.O.

Patent number: 5892205Abstract: Connecting conductors located within at least one heating field for heating conductors are configured so that they do not luminate in operation and are not bowed or shifted out of place by thermal loading. For this purpose the conductor is corrugated and also securely anchored at regular center-spacings, it having with respect to the heating resistor greater resistance cross-sections. This achieves for a very simple construction an optically advantageous glow pattern of the heater in every operating mode.Type: GrantFiled: May 14, 1996Date of Patent: April 6, 1999Assignee: E.G.O.

Patent number: 5489764Abstract: In a radiant heating unit the temperature sensor (30) of a temperature limiter (29) extends over only part of the diameter of the heating field (17) in which the radiation heaters (13) are located. The temperature sensor is so constructed and/or mounted, that it exerts a pressure on the mounting support (44), e.g. in the form of a projecting member of the insulator (7), which is, e.g., located in the center of the heater. Thus, it keeps the insulation under a certain pretensioning pressure and it is simultaneously prevented that it is raised upwards and comes too close to the heated plate.Type: GrantFiled: September 28, 1994Date of Patent: February 6, 1996Assignee: E.G.O. Electro-Gerate Blanc u FischerInventors: Siegfried Mannuss, Eugen Wilde

Patent number: 5393958Abstract: Heating resistors and/or series resistors (10) are curved in flat corrugation manner from flat band and are so pressed into the bottom (7) of an insulation (3), that they are only prevented by friction from rising from the bottom (7). The resistor (10) has non-offset, uninterrupted, through-edge faces (14, 15). Thus, in the case of a very simple construction, a surface-specific, high power density can be obtained.Type: GrantFiled: September 2, 1993Date of Patent: February 28, 1995Assignee: E.G.O. Elektro-Gerate Blanc u. FischerInventors: Martin Gross, Eugen Wilde

Patent number: 5309133Abstract: In the manner of a tubular heater, a temperature sensor comprises a metallic tubular jacket with internal resistance wire coil embedded in insulating material and closing pieces having electrical connection members, so that a very simple, robust and high temperature-resistant temperature sensor with a measuring range up to e.g. approximately 750.degree. C. is obtained. The temperature sensor jacket can be earthed or grounded. For operating the temperature sensor there is appropriately a test current in the mA range in the case of a test voltage in the mV range, whose temperature-dependent changes are processed by means of an electronic amplifier.Type: GrantFiled: February 7, 1992Date of Patent: May 3, 1994Assignee: E.G.O.

Patent number: 5223697Abstract: The rim of an electric radiant heater is formed by a multilayer body (13). It can have the cross-sectional shape of a U, whose interior is filled with a good insulating material. In the interior (23) is placed a sensor coil (23) for a pot detection system, where it is well shielded against heat and mechanical influences.Type: GrantFiled: December 6, 1991Date of Patent: June 29, 1993Assignee: E.G.O.

Patent number: 5153413Abstract: A radiant heating element (11) contains on the surface (16) of an insulating support (14) heating resistors (18), which emanate from terminals (20), which are arranged in regular spacings on the outer circumference of the heating area (21) and are connected there to semicircular ring circuits (22, 23). The heating resistors run from the outside to the inside in nested double spirals (30, 31), reverse there in return bends (32) and then run parallel back again to the outside. This gives a very uniform, almost completely symmetrical arrangement, so that the glowing state is rapidly reached and a uniform glow pattern is obtained.Type: GrantFiled: July 12, 1991Date of Patent: October 6, 1992Assignee: E.G.O. Elektro-Gerate Blanc u. FischerInventor: Eugen Wilde

Patent number: 5113170Abstract: A temperature switch for limiting the temperature of a glass ceramic plate against the radiation emanating from light and dark radiators has a sensor, which comprises a metallic sensor tube and an inner ceramic rod. Over the sensor is drawn a steatite tube, which on the one hand ensures the electrical insulation between the heaters and the glass ceramic plate and on the other so shields the radiation by reflection, absorption and thermal mass, that the sensor is given a temporary response delay and a greater switching hysteresis.Type: GrantFiled: September 6, 1990Date of Patent: May 12, 1992Assignee: E.G.O. Elektro-Gerate Blanc u. FischerInventors: Gerhard Goessler, Eugen Wilde
