Abstract
Disclosed is the operation method for a towel-washing course in a washing machine, in which the towel is dehydrated at the spin speed of 900 rpm and 1100 rpm, which is greater than the spin speed (800 rpm) of the drum in the main dehydration process for general laundry, a water level of 22 kHz or 23 kHz, higher than a water level (23.2 kHz) for the general laundry, is supplied to the towel, the towel has a rinse time of 8 or 12 minutes, which is longer than that of 4 minutes for the general laundry, and rinse temperature for the towel is in the range of 50° C.˜60° C., relatively higher than that of 40° C. used to rinse the general laundry. Further, the rinse process having the remaining water removal process is performed between the main dehydration and the water supply, thereby removing detergent solution with a certain concentration from the inside of the washing machine after completing the main dehydration process. Accordingly, clean water is supplied, thereby smoothing the rinse process for the towel, thus to solve the problem of detergent remnants in the towel after rinsing the towel.
