Dryer and operation method thereof

Abstract

Provided are an operation method of a dryer, and a dryer performing the operation method. The operation method includes detecting, by using one or more sensors, first laundry that is loaded into the dryer; obtaining data related to a washing process with respect to second laundry that was loaded into the washing machine before the first laundry is loaded into the dryer; determining whether the first laundry corresponds to the second laundry, based on data related to the washing process with respect to the second laundry; based on determining that the first laundry corresponds to the second laundry, determining a weight of the second laundry before washing as a first target dry weight; and outputting information about a drying state of the first laundry, based on at least one of a drying time period set in the dryer and whether the weight of the first laundry reaches the first target dry weight.

   the outputting of the information about the drying state of the first laundry comprises outputting the information about the drying state of the first laundry based on the weight of the first laundry reaching the second target dry weight, and   the second target dry weight is less than the weight of the second laundry before washing.   
     
     
         8 . The operation method of  claim 2 , further comprising:
 determining fabric characteristics of the second laundry, based on the data related to the washing process with respect to the second laundry; and   based on determining that the first laundry corresponds to the second laundry, determining setting values of the dryer for drying the first laundry, based on the fabric characteristics of the second laundry.   
     
     
         9 . The operation method of  claim 8 , wherein the fabric characteristics of the second laundry are obtained by applying, to an artificial intelligence model, the flow rate of water introduced in the washing process, the moisture content of the second laundry, and the washing mode applied to the washing process. 
     
     
         10 .
