Patent number: 7461801Abstract: A multi-functional food processor contains a machine body and a top cover. It further includes a container and a driving device. The drive shaft of the driving device is extended to the container, and a juicer shredder, a vegetable shredder or a meat grinder blade is selectively installed in the transmission shaft, which is connected to the drive shaft. The top cover is provided with two feed tubes, where the first feed tube is used for feeding vegetables and fruits in conjunction with a first pusher. The second feed tube is used for feeding vegetables or meat into a vegetable shredder or a meat grinder blade in conjunction with push of the second pusher. A safety switch is mounted between the feed tubes, and it allows only one pusher to operate in each sole feed tube thus avoiding the food being fed into the wrong feed tube.Type: GrantFiled: January 5, 2007Date of Patent: December 9, 2008Assignee: Lyu Jan Co., Ltd.Inventor: Li-Chen Wu Chang

Publication number: 20080185467Abstract: A food processor having gear-shifting function includes a machine body, gear-shifting and non-gear-shifting cutting assemblies. Each of the cutting assemblies includes a fixed seat and a rotating seat. The rotating seat is assembled onto the fixed seat via a shaft and a bearing, so that the rotating seat is able to freely rotate relatively to the fixed seat. The non-gear-shifting cutting assembly is not mounted with the gear-shifting mechanism; therefore, when the cutting assembly is installed on the drive shaft of the motor, the cutting assembly is to output at the same speed as that of the motor. The gear-shifting cutting assembly is disposed with a gear-shifting mechanism in the fixed seat. Therefore, when the drive shaft of the motor rotates, the shaft is to rotate by the gear-shifting output via the gear-shifting mechanism, which makes the blade mounted on the rotating seat to rotate at a gear-shifted speed.Type: ApplicationFiled: February 5, 2007Publication date: August 7, 2008Inventor: LI-CHEN WU CHANG

Publication number: 20080163767Abstract: A juice extractor with a safety device is disclosed herein, wherein the improvement includes the juice extractor including a switching device and an actuating part. The switching device is disposed by a feed channel of a juice extractor, and the actuating part is disposed on a food pusher. According to another embodiment of the present invention, the switching device is disposed by an opening of a cup body of the juice extractor and the actuating part is disposed on a lid. When the food pusher is put into the feed channel or the lid securely covers the opening of the juice extractor, the actuating part actuates the switching device to turn on the power. When the food pusher or the lid is removed, the switching device turns off the power, thereby achieving safety for operating the juice extractor.Type: ApplicationFiled: January 8, 2007Publication date: July 10, 2008Inventor: Li-Chen Wu Chang

Publication number: 20070089615Abstract: A grind blade assembly for juice extractors includes a fixed and ring-shaped upper grind blade with first teeth located on an underside thereof and a rotatable lower grind blade which is located beneath the upper grind blade and has a plurality of second teeth defined in a ring-shaped area of a top surface of the lower grind blade. The second teeth are located corresponding to the first teeth. A plurality of first blades protrude from the top surface of the lower grind blade and located close to the center of the lower grind blade. A plurality of second blades are located between the first blades and the second teeth on the lower grind blade.Type: ApplicationFiled: October 21, 2005Publication date: April 26, 2007Inventor: Li-chen Wu Chang
