Patent number: 6880902Abstract: A storage unit for a refrigerator includes a flexible support made of nylon, wire, or any other similar flexible material. The storage unit includes a load support zone which varies in shape depending upon items placed thereon. Most preferably, at least the load support zone is constituted by a mesh which permits the flow of cooling air through the storage unit. The storage unit includes at least one attachment element for securing the flexible support directly to a refrigerator shelf and/or a liner of the refrigerator. The storage unit can be releasably attached or can be a permanent, but collapsible, fixture within the refrigerator.Type: GrantFiled: March 12, 2003Date of Patent: April 19, 2005Assignee: Maytag CorporationInventor: Robert C.

Publication number: 20020184895Abstract: A temperature controlled drawer assembly incorporates a thermoelectric device and a control system to selectively heat or cool the contents of a drawer which is selectively movable into and out of a cabinet designed to be part of an end table, such as a nightstand, or other cabinet remote from a household kitchen. In a cooling mode of operation, a fan, disposed in the cabinet, draws air from inside the drawer and blows the air over a cold side of a heat sink to cool the air. The treated air is blown through plenums, back into the drawer. At the same time, heat is drawn away from the cold side and directed out of the cabinet. The current through the heat sink may be reversed to flip the cold and hot sides of the heat sink to enable the contents of the drawer to be heated.Type: ApplicationFiled: June 8, 2001Publication date: December 12, 2002Applicant: Maytag CorporationInventors: Ronald K. Anderson, Sheldon W. Mandel, Robert C. Zimmerman

Patent number: 5911750Abstract: An air flow system for the freezer compartment of a refrigerator includes air inlets located at an upper rear portion of the freezer compartment which direct a supply of cooling air forward and against both top and side walls of the compartment. The air then flows along an upper portion of the compartment toward a front thereof where it is re-directed downward and rearward. The bottom wall of the freezer compartment is provided with a plurality of upstanding, laterally spaced ribs upon which food items can be supported. Since the ribs are spaced, numerous channels are formed which extend from the front portion of the compartment to adjacent the rear wall. A gap is preferably created between the rear wall and the ends of the ribs such that air is permitted to flow laterally along a lower rear portion of the compartment. Air outlets or returns are also provided in the lower rear portion of the compartment for recycling of the air.Type: GrantFiled: June 4, 1997Date of Patent: June 15, 1999Assignee: Maytag CorporationInventors: Sheldon W. Mandel, Scott T. Tunzi, Kyle Bryant VanMeter, Robert C. Zimmerman, Paul V. Sikir

Patent number: 5525055Abstract: A cap for closing the burner of a liquid fuel cell and protecting the burner wick. The burner wick has upraised adjustable tabs that can be separated to control the heat output of the cell. The cap contains a die member that is arranged to move between the tabs when the cap is closed over the burner to position the tabs at a desired standard heat setting that is best suited for a majority of fuel cell applications.Type: GrantFiled: March 2, 1995Date of Patent: June 11, 1996Assignee: Hollowick, Inc.Inventors: J. Alan Menter, Robert C. Zimmerman

Patent number: 5228771Abstract: A table lamp that utilizes a fuel cell having a hollow glass or plastic envelope that includes an elongated body section joined to an expanded base by a pinched neck, and a flame shield mounted upon the top of the body section. The fuel cell has an elongated fuel container that rests upon the pinched neck of the envelope and a burner that is positioned within the flame shield. The flame shield has a top opening that permits the fuel cell to be inserted or removed from the envelope therethrough. A shade may be removably mounted upon the flame shield and a decorative insert slidably positioned between the fuel cell and the body of the envelope.Type: GrantFiled: March 23, 1992Date of Patent: July 20, 1993Assignee: Hollowick, Inc.Inventor: Robert C.
