Patent number: 10378808Abstract: An ice level sensor in an appliance that includes an ice storage housing and an ice maker. The housing receives ice from the ice maker. The ice level sensor includes a control circuit and one or more electrode arrays capable of detecting ice in the housing. The electrode arrays each contain one or more sense electrodes, and the control circuit detects ice in the housing based on a measurement of capacitance of the sense electrode(s). When the sensor detects that ice in the housing has reached a threshold level, the sensor can stop the ice maker from depositing more ice into the housing, to prevent overflow. The ice level sensor detects that ice has reached a threshold level by detecting changes in capacitance of a sense electrode or by detecting that the capacitance of a sense electrode reached a predetermined value.Type: GrantFiled: August 19, 2015Date of Patent: August 13, 2019Assignee: Marquardt GmbHInventors: David J. Fassett, Tony Zhang

Patent number: 10378816Abstract: A food prep table may include an upper chilling zone and a lower chilling zone, with each chilling zone containing an evaporation coil system, such as a TurboCoil™ system. The two evaporation coil systems are monitored and controlled by a dual thermostat and control unit (500) having temperature sensor probes in each chilling zone and controlling solenoid valves within each evaporation coil system. By the artful use and implementation of the dual thermostat and control unit, and by the artful use of T junctures in refrigerant supply and return lines, the disclosed embodiments enable a single condensing unit (600) to service both evaporation coil systems to achieve new efficiencies in the cost, refrigeration capacity, and thermal and mechanic attributes of the system. Moreover, an efficient dual air over air flow assembly is disclosed wherein chilled air is moved within the upper chilling zone in a manner that leverages the native configuration and cabinet surface areas of the evaporation coil systems.Type: GrantFiled: July 29, 2016Date of Patent: August 13, 2019Inventor: Hector Delgadillo
