Title: Smart food waste disposal device
Inventor: SEO YOUNG KAB
IPC: F26B3/30
Filed: 2019-09-26
Abstract: The present invention provides a smart food waste disposal apparatus in order to solve the following problems. When drying with a hot air circulation structure to dry a large amount of moisture in the food waste, odors generated from the food waste are discharged to the outside, making the surrounding environment and indoor air turbid. When hard foreign substances such as spoons and chopsticks are inserted in addition to a large amount of food waste, the rotary blade is broken and abraded, and a load is generated on the food waste disposal apparatus, which shortens the lifespan. In addition, there is a risk of a safety accident when a user puts his or her hand into the hopper and tries to take it out. The smart food waste disposal apparatus includes a food waste disposal unit and an application control unit. Accordingly, the food waste can be pulverized smoothly, and the operation can be automatically stopped when spoons, chopsticks, and other foreign substances are included in the pulverization of the food waste. It is possible to prevent malfunction of the device by notifying the manager of an abnormality, to dry the pulverized food waste quickly, and to block the odor generated from the food waste from being discharged to the outside during drying. In addition, the status of the smart food waste disposal apparatus can be checked in real time through a linked smart terminal.
