Patent number: 7348527Abstract: A microwave oven for use in cooking food having a door and door mounted controls and a cooling system where the door mounted controls are disclosed. The microwave oven having an external enclosure defining an outer cabinet and an oven cavity supported within the external enclosure where the oven cavity has a front access opening. The door is rotatably supported adjacent the external enclosure for selectively closing the access opening. A control unit is mounted within the door and a ventilation cooling path is formed within the door for cooling the control unit mounted with the door. A blower is supported within the external enclosure for directing an air flow toward the door and into the ventilation cooling path. The microwave can further include a housing which is supported within the door for enclosing the control unit and where the housing forms part of the ventilation cooling path.Type: GrantFiled: November 3, 2006Date of Patent: March 25, 2008Assignee: Whirlpool CorporationInventors: Eckart Braunisch, Ulf Nordh, Per Torngren, Anders Zeijlon, Hakan Lundstrom, Hans Lindgren, Hakan Carlsson, Alan D.

Patent number: 7193195Abstract: A filter system for a wall mounted type microwave oven, which has an external enclosure surrounding an oven cavity. The external enclosure includes a bottom closure wall having a suction opening. The external enclosure also includes a top vent opening. An air exhaust path is formed between the external enclosure and the oven cavity wherein air drawn into the suction opening passes through the air exhaust path and is exhausted through the top vent opening. A first filter is provided on the suction side of the air exhaust path and a second filter may be provided on the exhaust side of the air exhaust path. In particular, the first filter may be provided adjacent the suction opening and a second filter may be provided adjacent the top vent opening, such that the first filter is provided at the inlet of the air exhaust path and the second filter is provided at the outlet of the air exhaust path.Type: GrantFiled: July 1, 2004Date of Patent: March 20, 2007Assignee: Whirlpool CorporationInventors: Hakan Lundstrom, Per Törngren, Hans Lindgren, Alan D.

Publication number: 20060011621Abstract: A wall mounted type microwave oven having an external enclosure including a bottom closure wall which includes a suction opening and a top vent opening and an oven cavity which is supported within the external enclosure. The oven cavity has a rearwardly stepped portion to maximize the usable space provided within the oven cavity. An air exhaust air path is formed between the external enclosure and the oven cavity and includes a bottom plenum, a pair of rear air channels and an upper plenum. The rearwardly stepped area divides the space between the oven cavity and the external enclosure into the two rear air channels. At least one blower is provided within the external enclosure for drawing air into the bottom plenum through the suction opening and exhausting the air out through a top exhaust opening which forms part of the top vent opening.Type: ApplicationFiled: July 1, 2004Publication date: January 19, 2006Inventors: Eckart Braunisch, Per Torngren, Hakan Lundstrom, Hans Lindgren, Hakan Carlsson
