Publication number: 20130020315Abstract: Supplied in a heating chamber (20) of the disclosed high frequency cooking device (1) are high frequency waves generated by oscillation of a high frequency wave generating device (21). On the bottom wall of the heating chamber (20), a roller stay (31) is mounted with and rotates a turn table (30). Between the bottom surface of the turn table (30) and the bottom wall of the heating chamber (20), a tilt limiting member is positioned which prevents the turn table (30) from being tilted to or beyond a prescribed angle. The tilt limiting member comprises a protrusion (50) formed on the bottom wall of the heating chamber (20), a protrusion (51) formed on the bottom surface of the turn table (30), and a linking stay (52) linking an arm (31b) of the roller stay (31).Type: ApplicationFiled: March 31, 2011Publication date: January 24, 2013Applicant: SHARP KABUSHIKI KAISHAInventors: Norikimi Tatsumu, Kenichi Aoyama

Patent number: 6127665Abstract: In a microwave oven, a driving motor is fitted inside a fitting member that is fixed to a cabinet. The upper part of the output spindle of the driving motor is disposed through the fitting member so as to protrude outward, and is fitted into the lower part of a linking member. The lower part of the rotary shaft of a turntable is fitted into the upper part of the linking member. The linking member is covered by a cover, and the lower part of the cover is fitted to the fitting member. On the upper part of and outside the cover, a coil spring for preventing leakage of radio waves is fitted so as to surround the rotary shaft. The coil spring is kept in close contact with the rim of a through hole formed in the bottom surface of a heating chamber. An overhang for drainage is formed in the linking member to prevent fluid from coming into contact with the output spindle.Type: GrantFiled: July 30, 1998Date of Patent: October 3, 2000Assignee: Sharp Kabushiki KaishaInventor: Norikimi Tatsumu

Patent number: 5935480Abstract: A metallic supplementary pot having superior heat conductivity is newly provided which is attached in the conventional nonmetallic specialized pot which is placed on a turn table mechanism of the microwave oven. When bread is made in the microwave oven, the supplementary pot containing material is attached in the specialized pot before cooking, and the specialized pot is attached to the drive shaft of the turn table mechanism in the oven cavity. Since the tip of the drive shaft is fit into the supplementary pot in this case, a vane member is attached to the drive shaft in the supplementary pot. When cooking is started, the vane member is turned with the rotation of the drive shaft and the material is kneaded into dough. Thereafter, the dough is heated uniformly and in a short time in the supplementary pot, and bread is completed.Type: GrantFiled: December 31, 1997Date of Patent: August 10, 1999Assignee: Sharp Kabushiki KaishaInventors: Nobuo Takeoka, Yoshikazu Yamamoto, Norikimi Tatsumu
