  • Patent number: 11968753
    Abstract: A countertop appliance temperature controller configured to provide improved temperature control of a resistive heating element heated cooking surface of a countertop appliance through the use of a noncontact thermal sensor. The temperature controller including a pair of electrical output contacts selectively coupleable to the resistive heating element of the countertop appliance, a user input configured to receive a desired temperature setpoint for the cooking surface of the countertop appliance, a noncontact temperature sensor configured to receive temperature information directly from the cooking surface of the countertop appliance, and a thermostat configured to adjust an electrical output of the pair of electrical output contacts to minimize a difference between the desired temperature setpoint and a perceived actual temperature of the cooking surface based on the received temperature information.

  • Publication number: 20230250891
    Abstract: A device for and method of releasing pressure from a pressure cooker using an arrangement of magnets that influence the opening and closing characteristics of a pressure relieve device used in a pressure cooker. The device configured using magnets which act to repel each other causing the pressure release valve to operating more quickly than valves relying on gravity to open.

  • Publication number: 20220071241
    Abstract: A digital pressure canner and related methods of operation that provide for improved safety and consistency during a food canning process by reducing temperature over and undershoot. The digital pressure canner includes a digital control operating with inputs from digital sensors to accurately control the canning temperature during the canning process. By reducing over and undershoot of canning temperatures, foods within the pressure canner are maintained at temperatures sufficient to kill any bacteria or microorganisms for the entire canning cycle. In order to verify operation of the digital canner at sufficient canning temperatures, mechanical safety devices, for example, a pressure relief valve can be utilized in conjunction with digital controllers and sensors to provide audible and visual feedback to a user during the canning process.
