Referring to FIG. 1 and FIG. 2 , it is an embodiment of the drying method of the washer-drying machine of the present invention, which includes a spin-drying step and a drying step.

As shown in Figure 1, the spin-drying and shaking-off step includes several dehydration stages and shaking-off stages. The spin-drying stage executes the spin-drying program, and the shake-off stage is set between each spin-drying stage. In the shaking and scattering stage, the shaking and scattering procedure is executed. During the running of the shaking and scattering procedure, it is judged whether the clothes are completely peeled off from the inner cylinder wall. When the judgment result is yes, the next dehydration stage is entered; when the judgment result is no, the shaking and scattering procedure is continued. program until the laundry is completely peeled from the inner drum wall. In the early dehydration stage, the clothes contain more water and are more likely to stick to the inner cylinder wall and are not easy to peel off. Therefore, by setting the shaking stage to completely peel the clothes from the inner cylinder wall, it can be ensured that in the later dehydration stage, the clothes will not be peeled off. It is attached to the inner cylinder wall to improve the drying effect.

The drying step is entered after the spinning and shaking step, and a drying procedure is performed in the drying step to dry the clothes.

The drying method of the above-mentioned all-in-one washing and drying machine can ensure that the laundry is finished after the final dehydration stage by setting a shaking and scattering stage between each dehydration stage, and by controlling the spin speed, dehydration time, shaking time, shaking speed, etc. It will not stick to the inner cylinder wall, which ensures high drying efficiency in the drying step and shortens the drying time. At the same time, the clothes are not easy to wrinkle, and no human intervention is required, realizing intelligent laundry.

Preferably, the maximum rotational speed of the inner cylinder in each dehydration stage increases sequentially from front to back. Preferably, the drying and shaking step includes 6 dehydration stages, and the maximum rotational speed of the inner cylinder in each dehydration stage is 400 rpm, 600 rpm, 800 rpm, 1000 rpm, 1200 rpm, and 1400 rpm in sequence.

In this embodiment, in order to improve the dehydration effect, the number of dehydration stages can be increased. Preferably, the maximum rotational speed of the inner drum in every two dehydration stages from front to back is equal, and the inner drum in every two dehydration stages from front to back The maximum speed increases sequentially. For example, as shown in Figure 1, the drying and shaking step includes 12 dehydration stages, and the maximum rotational speed of the inner cylinder in each dehydration stage is 400rpm, 400rpm, 600rpm, 600rpm, 800rpm, 800rpm, 1000rpm, 1000rpm, 1200rpm, 1200rpm, 1400rpm in sequence. , 1400rpm.
