Disclosed are a washer for adjusting an amount of detergent and a method of driving the same, which controls an automatic detergent dispenser to decide the amount of detergent on an amount of contamination of laundry by using artificial intelligence or machine learning, and to input the determined amount of detergent to washing water.

A method of operating and a laundry treating appliance, including a rotatable drum at least partially defining a treating chamber into which laundry may be placed for treatment according to a cycle of operation, a processor programmed to at least as the laundry is being placed in the treating chamber, at least one of measure, sense, analytically determine, estimate, or receive as an input used to determined a load size. A laundry fill indicator indicates information related to the determined load size.

A control method for a clothes drying apparatus that aims to solve the problem of a load being prone to entangling when an existing clothes drying apparatus is used for drying a large load. For this purpose, the control method for a clothes drying apparatus includes: determining the size of a load in a load determining stage; and when the load is a large load, controlling a drying drum to rotate unidirectionally in a first heating stage, and controlling the drying drum to alternately rotate normally and reversely in a second heating stage. Accordingly, a drying effect can be guaranteed while the load is effectively prevented from being knotted and entangled, and the drying time is shortened.
