Patent number: 9271628Abstract: A dishwasher includes an outer housing, a drawer having front, rear, bottom and opposing side walls that collectively define a washing tub, a lid for selectively closing the washing tub and an operating mechanism that raises and lowers the lid as the drawer is shifted into and out of the outer housing. The operating mechanism includes a lifting slider slidably mounted in the outer housing operatively coupled to a lifting spring and a compression slider, also slidably mounted in the outer housing coupled to a compression spring. The lifting slider and compression slider are provided with corresponding lifting rollers and compression rollers that engage the lid. As the drawer is withdrawn from the outer housing, the lifting spring urges the lifting slider upward raising the lid and, as the drawer is inserted into the outer housing, the compression slider forces the lid downward onto the washing tub.Type: GrantFiled: May 6, 2010Date of Patent: March 1, 2016Assignee: Whirlpool CorporationInventors: Kory A. Gunnerson, Kristen K. Hedstrom, Mark E. Palm, Rodney M. Welch, Jeffrey N. Williams

Patent number: 8734595Abstract: A dishwasher includes a first washing chamber and a second washing chamber capable of performing a washing operation separately and/or concurrently. Each washing chamber includes a wash pump, a drain pump and a heating unit that are operatively connected to a controller. When initiating a washing fluid in one washing chamber, the controller determines if the other washing chamber is active. If the other washing chamber is active, the heating unit for the one washing chamber is operated at a low power level. However, if the other washing chamber is inactive, the one washing chamber is operated at a high power level to rapidly heat the washing fluid and thus shorten the duration of the washing operation.Type: GrantFiled: October 1, 2013Date of Patent: May 27, 2014Assignee: Whirlpool CorporationInventors: Kristen K. Hedstrom, Mark E. Palm, Rodney M. Welch

Patent number: 7850784Abstract: A drawer-type dishwasher includes a frame assembly, a wash tub slidably mounted in the frame assembly, and a lid member. The lid member can be lowered onto the wash tub when the wash tub is shifted into the frame assembly, and raised when the wash tub is shifted out of the frame assembly. The lid member includes a seal element that abuts the wash tub when the lid member is lowered. The seal element includes a base portion, an angled, deflecting finger portion and a flat pad portion which projects from the base portion. When the seal element is urged against the wash tub, a compressive force is applied to the flat pad portion causing the deflecting finger to seal against the wash tub in a manner that substantially shields the deflecting finger from excessive compressive forces.Type: GrantFiled: November 29, 2005Date of Patent: December 14, 2010Assignee: Maytag CorporationInventors: Kory A.
