Publication number: 20230363582Abstract: A contact grill includes upper and lower grill assemblies connected together by a hinge assembly. Contact grills of the present invention are advantageously easier to clean including components that can be submerged in water or washed within a dishwasher. In one aspect of the present invention, the upper and lower grill assemblies are fully separable from one another and from the hinge assembly so that the upper and lower grill assemblies, each comprising a housing, grill plate, and heating element, are free of electrical components so that they can be submerged or washed in a dishwasher. In another aspect of the present invention, upper and lower grill plates that are assembled with respective upper and lower heating elements are separable from an assembly of upper and lower housings connected together with a hinge assembly.Type: ApplicationFiled: September 30, 2021Publication date: November 16, 2023Inventors: Firdaus Sameer Nandoliya, Noah C. Pulvermacher, Maciej Murzynski, Jacob D. Smith, Benjamin M. Cleppe

Publication number: 20230355032Abstract: An electrical appliance includes a controller operatively connected to a power circuit, a control circuit, a power source, a sensor for sensing a parameter level, and an active element. The controller is configured to receive an input of the parameter level from the sensor and to output a duty cycle for controlling a power level of the active element via the control circuit at various times to achieve a target set point of the parameter, the duty cycle based on proportional and integral control. The controller uses the proportional control and the integral control when the control circuit is energized, and accumulates integral error only when a parameter process variable sensed by the sensor is determined to be within an interval of the target set point.Type: ApplicationFiled: September 28, 2021Publication date: November 9, 2023Inventors: Noah C. Pulvermacher, Benjamin M. Cleppe, Drew W. Heidenreich, Sean P. Holinka, Jacob D. Smith, Maciej Murzynski, Grant T. Oberhauser, Firdaus S. Nandoliya, David W. Everett

Publication number: 20210378445Abstract: Contact grill designs with features that reduce the production of smoke and that otherwise diffuse smoke to reduce the visibility of the smoke as such smoke made up of a combination of steam and burned grease is generated during the cooking of a food product such as a meat product. Contact grills make use of passive air flow in one or both of upper and lower grill housings to reduce production of smoke and to better diffuse smoke to reduce smoke visibility exiting a cooking chamber of the contact grill.Type: ApplicationFiled: October 3, 2019Publication date: December 9, 2021Inventors: Firdaus Sameer Nandoliya, Maciej Murzynski, Boopalan Sampath, Jacob Daniel Smith

Patent number: 7191522Abstract: In a cutting blade assembly for an electric foil shaver, a first cutting blade of the assembly has a generally planar first face, a generally planar second face opposite the first face, and a peripheral cutting edge. The first cutting blade has at least one bump disposed on its first face. A second cutting blade of the assembly has a generally planar first face, a generally planar second face opposite the first face, and a peripheral cutting edge. The first and second cutting blades are arranged in generally parallel relationship with each other with the first face of the first cutting blade facing either the first face or the second face of the second cutting blade.
