Abstract:
A laundry fresh air treatment method for a laundry treatment device, comprising: after washing is completed, enabling a fan (5) be turned on and to rotate at a first set rotational speed, and enabling an inner drum (2) to rotate at a first set turn-to-stop ratio; after a set time, enabling the fan (5) to rotate at a second set rotational speed and enabling the inner drum (2) to rotate at a second set turn-to-stop ratio, the first set rotational speed being greater than the second set rotational speed, and the first set turn-to-stop ratio being greater than the second set turn-to-stop ratio; or obtaining the weight of the laundry in a washing stage; after washing is completed, determining whether the weight of the laundry is greater than or equal to a preset value; if the weight of the laundry is greater than or equal to the preset value, then enabling the inner drum (2) to rotate at the first set turn-to-stop ratio and turning on the fan (5) so as to introduce fresh air into an outer drum (3); and if the weight of the laundry is less than the preset value, then enabling the inner drum (2) to rotate at the second set turn-to-stop ratio and turning on the fan (5) so as to introduce fresh air into the outer drum (3), the first set turn-to-stop ratio being greater than the second set turn-to-stop ratio. According to the method, after washing is completed, laundry is air-dried by using outside air, which is advantageous for quickly removing water vapor and residual odors on the laundry, preventing wear and tear of the laundry, and improving user experience.
