Patent number: 4413175Abstract: A method for indicating the thermal state of cooking appliances with an optical and/or acoustic signalling device, comprising the steps of: counting forward from a starting number in response to the heating means of the cooking appliance being switched on; and, counting backwards after the heating means of the cooking appliance has been switched off, the signalling device being switched on when the count exceeds a first number and being switched off when the count falls below a second number.Type: GrantFiled: January 22, 1981Date of Patent: November 1, 1983Assignee: E.G.O. Regeltechnik GmbHInventors: Wilfried Schilling, Siegberg Lorenz, Friedrich Koch

Patent number: 4381438Abstract: A cooker apparatus for heating a cooking pot inductively comprises an induction heating coil and a control device for controlling the heating power. The control device has a temperature-dependent guiding and control means and a sensor unit, adapted to be positioned on the cooking pot and subjected there to the evolution of steam in the cooking pot. The sensor unit is arranged to transmit control signals to the guiding and control means.Type: GrantFiled: June 3, 1981Date of Patent: April 26, 1983Assignee: E.G.O. Regeltechnik GmbHInventors: Gerhard Goessler, Friedrich Koch

Patent number: 4302662Abstract: A control instrument is used for the manually continuously adjustable supply of electric power to electric hot plates in the form of individual power pulses. The control instrument contains a switch, operated by a bimetallic member, whose heater is controlled by an electronic circuit and supplies current to the heating means in individual half-waves. An automatic initial cooking device with an electronic timing member is provided which, during the initial cooking phase, reduces the power supply to heater in a predetermined ratio and consequently correspondingly increases the power supplied to the electric hot plate. The automatic initial cooking device is automatically switched on by the control instrument knob. By rotating the control knob beyond a median power limit the automatic initial cooking device is switched off.Type: GrantFiled: August 16, 1979Date of Patent: November 24, 1981Assignee: E.G.O. Regeltechnik GmbHInventors: Robert Kicherer, Wilfried Schilling

Patent number: 4214151Abstract: 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.Type: GrantFiled: July 5, 1978Date of Patent: July 22, 1980Assignee: E.G.O. Regeltechnik GmbHInventors: Robert Kicherer, Wilfried Schilling

Patent number: 4206344Abstract: A power controller for controlling the intermittent supply of current to a load, such as a cooker hotplate, has a pivotally mounted snap switch controlled by a heated bimetal member which is heated in dependence upon the connected power. A compensating bimetal strip, for taking ambient temperature into account, is arranged on the snap switch and parallel thereto. A control cam acts on the free end of the compensating bimetal strip. The latter is shielded from the heat of the heated bimetal member.Type: GrantFiled: June 2, 1977Date of Patent: June 3, 1980Assignee: E.G.O. Regeltechnik GmbHInventors: Karl Fischer, Robert Kicherer
