Patent number: 11866918Abstract: The present invention relates to a food waste disposer that is configured to allow an opening and closing plate adapted to open and close a drain pipe to be open only when a motor operates, so that normally, the drain pipe from which water is discharged is closed, thereby preventing bad smell and sewage from flowing backward from the drain pipe, to allow a propeller adapted to forcedly discharge the water from a casing to the drain pipe to be driven reversely and to thus close the opening and closing plate if the motor is driven reversely, so that gears inside a pulverizing part rotate to circulate the water in the casing and thus to automatically clean the casing, without any separation of the casing, and to allow a magnetic material to be built in a hopper so that if iron introduced into the hopper is sensed by sensors, the pulverizing part stops working and is thus prevented from being damaged by the iron.Type: GrantFiled: November 12, 2020Date of Patent: January 9, 2024Inventor: Yong-Goo Kim
