Publication number: 20240167753Abstract: An appliance cabinet includes an outer wrapper that encloses an inner liner. The outer wrapper defines an integrally formed machine compartment. A vacuum insulated structure is defined between the outer wrapper and the inner liner. A selectively removable side access panel is removably coupled to the outer wrapper. The selectively removable side access panel includes a central body with support ribs and an arcuate offset flange that extends orthogonally from the central body. Vertical supports are operably coupled to the top and the bottom of a frame and define at least one retention slot. The selectively removable side access panel includes at least one retention tab selectively disposed within the at least one retention slot.Type: ApplicationFiled: January 29, 2024Publication date: May 23, 2024Applicant: WHIRLPOOL CORPORATIONInventors: Koteswara Rao Gochika, Narendra A. Kapure, Manjunathraddi Navalgund, Manoj T. Sambrekar

Publication number: 20240133613Abstract: A refrigeration unit includes a cabinet and a first evaporator assembly. The first evaporator assembly is operable between an uninstalled condition and an installed condition. In the uninstalled condition, the first evaporator assembly is not assembled with the cabinet. In the installed condition, the first evaporator assembly is assembled with the cabinet. The first evaporator assembly includes a first evaporator, a first suction line connected to the first evaporator at a first suction line joint, and a first capillary tube connected to the first evaporator at a first capillary tube joint. The first suction line joint and the first capillary tube joint of the first evaporator assembly are leak testable in the uninstalled condition of the first evaporator assembly.Type: ApplicationFiled: December 29, 2023Publication date: April 25, 2024Applicant: Whirlpool CorporationInventors: Vishal B.

Patent number: 11953258Abstract: A refrigerating appliance includes a refrigerating cabinet that has an outer wrapper. A machine compartment is disposed proximate a rear bottom of the refrigerating cabinet. The machine compartment is defined by selectively removable side panels, an inner curved surface of the outer wrapper, and a bottom support plate. A controller is disposed within the machine compartment. Reinforcement segments extend from a planar extent of the outer wrapper to a lip of the bottom support plate.Type: GrantFiled: February 13, 2023Date of Patent: April 9, 2024Assignee: Whirlpool CorporationInventors: Koteswara Rao Gochika, Narendra A.

Patent number: 9590412Abstract: A solid state power controller (SSPC) for an electrical power distribution system (EPDS), the SSPC may include a solid state switching device (SSSD) configured to interrupt current in a feeder line of the EPDS and a processing engine. A clamping device may be interposed between the feeder line and an electrical ground of the EPDS, An opto-coupler may be interposed between the processing engine and the clamping device. The opto-coupler may coupled to the clamping device to provide a lightning-detected signal to the processing engine only when a voltage drop develops across the clamping device. The processing engine may be constrained from commanding an alteration of state of the SSSD upon receiving the lightning-detected signal.Type: GrantFiled: January 2, 2015Date of Patent: March 7, 2017Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Ezekiel Poulose, Vinod Kunnambath, Prashant Purusmotham Prabhu K, Narendra Rao, Zhenning Liu, Randy Fuller

Patent number: 8847656Abstract: A system that drives multiple MOSFETs in parallel for direct current and alternating current solid state power controller applications may include networks connected to the gates of the MOSFETs to protect the MOSFETs from being damaged during high current interruption. For direct current applications, the system may include a switching protection and damping network and a gate drive balancing network. For alternating current applications, the system may include two switching protection and damping networks and a gate drive balancing network.Type: GrantFiled: July 3, 2013Date of Patent: September 30, 2014Assignee: Honeywell International Inc.Inventors: Ezekiel A, Zhenning Liu, Vinod Kunnambath, Prashant Purushotham Prabhu K, Randy Fuller, Narendra Rao

Patent number: 8716997Abstract: Pre-charge circuitry allows capacitive loads connected to a solid state power controller to be gradually charged up by a PWM, generated with a cycle by cycle current limit, switching a single MOSFET in series with an inductor, before the SSPC is turned on. The pre-charge circuitry may require only three additional components, e.g., a MOSFET, an inductor and a diode, along with a designated MOSFET gate driver.Type: GrantFiled: June 16, 2010Date of Patent: May 6, 2014Assignee: Honeywell International, Inc.Inventors: Narendra Rao, Vinod Kunnambath, Prashant Purushotham Prabhu K, Ezekiel Poulose Aikkaravelil, Randy Fuller, Zhenning Liu

Patent number: 8704574Abstract: A power distribution system includes the use of a master digital signal processor (DSP) and two slave DSPs connected to the master DSP. The slaves DSPs may be connected to each of a plurality of solid state power channels (SSPC) controlling power distribution functions to each of the channels. A power control strategy may use one power supply for the master DSP, a second power supply shared between the slave DSPs, and a third power supply shared between each of the SSPC channels.Type: GrantFiled: February 13, 2012Date of Patent: April 22, 2014Assignee: Honeywell International Inc.Inventors: Prashant Purushotham Prabhuk, Narendra Rao, Ezekiel Poulose Aikkaravelil, Vinod Kunnambath, Randy Fuller, David Lazarovich, Zhenning Liu
