Patent number: 6630655Abstract: A heating chamber has a width in a direction of a two-head arrow X, a depth in a direction of a two-head arrow Y and a height in a direction of a two-head arrow Z. An infrared sensor includes 25 infrared detection elements each having a field of view. Since the 25 infrared detection elements are arranged, five by five in directions Y and Z, on the heating chamber's bottom plate there are projected a total of 25 fields of view, five by five in directions Y and X. Thus the bottom plate has any area thereof covered by one of the 25 fields of view.Type: GrantFiled: April 26, 2001Date of Patent: October 7, 2003Assignee: Sanyo Electric Co., Ltd.Inventors: Eiji Fukunaga, Masaru Noda, Kazuo Taino, Kenji Kume, Masahiro Tanaka, Eiji Mukumoto

Patent number: 6590192Abstract: A microwave oven determines an appropriate time to stop heating even if multiple food items are placed in the heating chamber. After any position on the bottom surface of the microwave oven reaches 75 deg C., a search is made for any other position having a temperature of at least 70 deg C. If such a position is detected, heating is concentrated on that position until it reaches 75 deg C. When all food-containing positions in the microwave oven have reached a temperature of at least 75 deg C., the heating operation performed by the magnetron is stopped.Type: GrantFiled: February 26, 2002Date of Patent: July 8, 2003Assignee: Sanyo Electric Co., Ltd.Inventors: Kazuo Taino, Hiroyasu Kitagawa, Kazuko Tanaka, Yoshiko Yamane

Patent number: 6586714Abstract: The microwave oven includes an infrared sensor for detecting the temperature of a food within a heating chamber. The infrared sensor has a field of view within the heating chamber. The infrared sensor is capable of moving the field of view. The food is often placed in the central region of the heating chamber. Therefore, when cooking is started, the field of view of the infrared sensor first scans the central region of the heating chamber.Type: GrantFiled: February 26, 2001Date of Patent: July 1, 2003Assignee: Sanyo Electric Co., Ltd.Inventors: Kazuhiko Kawamura, Hiroyuki Uehashi, Masaru Noda, Eiji Fukunaga, Kazuo Taino

Patent number: 6563097Abstract: A microwave oven heats all food in an appropriate manner even if food items are simultaneously placed at multiple locations in a heating chamber. An auxiliary antenna is periodically stopped at an orientation corresponding to a position where a lowest temperature was detected at the start of the heating operation. Between stopped periods, the auxiliary antenna is rotated for a period to apply heat evenly to all food in the oven. If multiple low-temperature points are detected, the central position of these multiple low-temperature points is used for applying concentrated heat.Type: GrantFiled: February 26, 2002Date of Patent: May 13, 2003Assignee: Sanyo Electric Co., Ltd.Inventors: Kazuo Taino, Hiroyasu Kitagawa, Kazuko Tanaka, Yoshiko Yamane

Patent number: 6376812Abstract: In a sake/milk heating process, the field of view of an infrared sensor is moved by a predetermined pattern in a heating chamber as an initial search. When the field of view is fixed after the initial search, if the temperature variation of an object within the field of view after a predetermined time has passed is equal to or lower than a specified value, various determinations are made, and the field of view of the infrared sensor is again moved in the heating chamber as a re-search. Thus, even if the field of view is fixed at a position where no food item is placed for some reason in the initial search, the field of view will not be fixed in the incorrect position and can be moved again.Type: GrantFiled: April 24, 2001Date of Patent: April 23, 2002Assignee: Sanyo Electric Co., Ltd.Inventors: Morito Yamada, Kazuo Taino, Kiyoshi Hiejima, Haruo Sakai, Hiroyuki Uehashi

Patent number: 6121596Abstract: In a cooking appliance, the foodstuff is placed on a turntable in a heating chamber. Infrared radiation emitted from the foodstuff is sensed by an infrared sense unit. The cooking appliance obtains the number of extrema of the amount of infrared radiation sensed over the period of one cycle of the turntable. The number of foodstuffs is determined according to the number of maxima. A control unit drives a heat unit according to the determined number of foodstuffs.Type: GrantFiled: May 27, 1999Date of Patent: September 19, 2000Assignee: Sanyo Electric Co., Ltd.Inventors: Kazuo Taino, Masaru Noda, Kazuko Tanaka, Chizuko Konishi

Patent number: 5932130Abstract: A cooking device measures the temperature of an object to be heated by means of an infrared sensor when a user operates a predetermined switch, when placement of the object to be heated in the heating chamber is detected, or when it is detected that the door of the heating chamber has simply been opened in the demonstration mode with a magnetron stopped. The measured temperature is displayed on the display unit, and the temperature measuring is ended when a predetermined time period elapses. This allows actual detection of the temperature of the object to be heated in the demonstration mode and hence a more persuasive demonstration.Type: GrantFiled: December 31, 1997Date of Patent: August 3, 1999Assignee: Sanyo Electric Co., Ltd.Inventor: Kazuo Taino

Patent number: 5919389Abstract: In the operation of a thoroughly heating course of a microwave oven, when an ordinary temperature food having a weight of less than 500 g is heated to a desired finishing temperature of 75.degree. C., heating is performed until the temperature of the food reaches 75.degree. C. by a normal output of 650 W (a first mode). After time t.sub.1 at which 75.degree. C. is reached, the food is heated and kept warm at 90.degree. C. higher than 75.degree. C. by a lower output of 350 W (a second mode). As a result, the food can be surely and thoroughly heated to the inside.Type: GrantFiled: February 27, 1998Date of Patent: July 6, 1999Assignee: Sanyo Electric Co. Ltd.Inventors: Hiroyuki Uehashi, Kazuo Taino, Kazuyuki Takimoto, Masaru Noda, Kayo Tsuzaki

Patent number: 4553011Abstract: In a microwave oven in which microwave heating is controlled by the output value of a temperature sensor, a microcomputer is provided to control the microwave heating in such a manner that the microwave heating is continued until the output value of the temperature sensor exceeds a first temperature, and once the output value exceeds the first temperature, the microwave heating is stopped for several periods of time and the output value of the temperature sensor is detected for avoiding the bad effect of noise due to the microwave oscillation.Type: GrantFiled: December 31, 1984Date of Patent: November 12, 1985Assignee: Sanyo Electric Co., Ltd.Inventors: Takeshi Nakata, Atsushi Horinouchi, Kazuo Taino
