Patent number: 7199341Abstract: A high-frequency heating apparatus comprises a heating chamber, a high-frequency generator, a waveguide, an antenna, a motor for rotating the antenna, and a stage (6) provided above and near the antenna to partition the heating chamber and made of dielectric. A rotary base on which an object to be heated is mounted is provided on the stage. A first magnet is provided to the antenna. A second magnet is provided on the rotary base at a place corresponding to the first magnet on the rotary base. By utilizing the magnetic coupling between the first and second magnets, the rotary base is rotated in synchronism with the rotation of the antenna. While maintaining the advantages of conventional antenna high-frequency heating apparatuses, the heating efficiency by grill heating or oven heating is enhanced, and minute heating uniformness is achieved.Type: GrantFiled: July 25, 2003Date of Patent: April 3, 2007Assignee: Sharp Kabushiki KaishaInventors: Fuminori Kaneko, Hiroki Kitayama, Yoshikazu Yamamoto, Yuzi Andoh

Patent number: 5568765Abstract: A microwave fryer includes a magnetron in the machine body; an oil vessel for storing oil to be heated by radiation of microwaves from the magnetron which is detachably disposed in a heating chamber of the machine body; and a detachable frying container, provided over the oil vessel in the heating chamber, having a screen portion which allows microwaves to pass therethrough when the container is immersed in the oil and which prohibits almost all microwaves from passing therethrough when the container is in the air. The frying container has a top opening which is sealed against microwaves. The apparatus further includes a lifting mechanism for moving one of the frying container and the oil vessel relative to the other, and a temperature detecting device for detecting the temperature of the cooking oil. In this arrangement, the oil held in the oil vessel detachably disposed in the heating chamber is heated by radiation of microwaves.Type: GrantFiled: June 5, 1995Date of Patent: October 29, 1996Assignee: Sharp Kabushiki KaishaInventors: Yuzi Andoh, Masaki Katabe, Hiromi Suenaga
