Patent number: 10859306Abstract: A mounting arrangement secures a refrigerator compressor to a support base member through a plurality of elastomeric mounts secured on pin elements with retainers. The mounts include head portions which extend through openings provided in an elongated plate fixed to the compressor. The mounts are specifically formed with a rounded bottom to pre-load the mounting arrangement and prevent vibration transmission through cores of the mounts. In addition, each mount includes a plurality of vertically spaced rings which provide shock protection against a large impact force by deflecting and potentially contacting each other, while normal vertical isolation occurs by deflection of an uppermost one of the rings. The mounts are formed with various undercuts which allow the mounts to be optimized for the mass and operational frequency of the compressor.Type: GrantFiled: June 6, 2019Date of Patent: December 8, 2020Assignee: Whirlpool CorporationInventors: Daniel J. Lesko, Kaveh Esmael

Patent number: 10563901Abstract: A refrigeration appliance includes an insulated cabinet having a side wall and a machine compartment positioned adjacent the side wall. An aperture is provided through the first side wall to allow air to flow into the machine compartment. An air vent is provided at the exterior surface of the side wall so as to cover the aperture. The air vent having a first set of louvers. A sound barrier is provided at the interior surface of the side wall at the aperture. The sound barrier has a second set of louvers, where the second set of louvers are positioned with respect to the first set of louvers such that there is no mechanical access to components in the machine compartment through the air vent, and such that sounds from within the machine compartment are dampened while still allowing air to flow through the air vent.Type: GrantFiled: November 13, 2018Date of Patent: February 18, 2020Assignee: Whirlpool CorporationInventors: Bruno Boehringer, Darci Cavali, Derek Lehman, Daniel J. Lesko, Kevin Noel, Douglas Pohl
