When microwave is supplied into a cavity of the microwave oven, the microwave is oscillated into the space of the body by the antenna and thus the microwave is deeply penetrated up to inside of the refrigerating load. Also, the microwave is secondly emitted into the space of the body from an edge of the slot, thereby completely defrosting the refrigerating load.Type: GrantFiled: October 28, 2005Date of Patent: July 24, 2007Assignee: LG Electronics Inc.Inventors: Won-Hui Lee, Eung-Su Kim

Patent number: 7217908Abstract: A removable filter/pod compartment is filled with coffee grounds, tea, or other espresso particulate brewing substance and mounted within a water reservoir. Water is placed in the water reservoir. A bottom cover is connected to upper cup assembly to hold the filter/pod compartment in place. A resilient gasket or valve is positioned between the filter/pod compartment and a filtrate passage. A filtrate splash cover may be attached to the upper edges of the filtrate reservoir. The assembled beverage maker is placed into a microwave oven. As water in the water reservoir begins to heat up, steam is generated, and hot water is displaced upwards through the filter/pod compartment and particulate brewing substance. The heated beverage is automatically emptied into the filtrate reservoir, which is designed to function as a drinking cup for individually-sized portions.Type: GrantFiled: March 17, 2005Date of Patent: May 15, 2007Assignee: Micro Lungo, Inc.Inventors: Mario Orrico, Stuart Kofard, Rudy Avramovich
