In a preferred embodiment of the application, during the drying process, the drying phase comprises at least: the control device is used for controlling the first holes to be opened in the rapid dehumidification stage and controlling the first holes to be closed in the wrinkle removal stage. In addition, the washing machine is also provided with a humidity detector for detecting the water content of clothes in the washing machine; the control device is connected with the humidity detection device and is also used for determining a drying stage according to the water content.

According to a circular air duct air volume calculation formula Q=V.times.F.times.3600s, F (square meters) is the air duct cross-sectional area, V (m/s) is the air duct air speed, and Q (m) ³ And/h) is air quantity, and F (square meter) =pi R is calculated by the cross section area of the circular air pipe ² R is the radius of the circular air duct. Typically, the air from the air outlet in the cylinder has two outlets, one is a return air outlet and the other is a rear cylinder wall hole outlet. When the air output is constant, namely Q (m ³ And/h) is the ration, the cross-sectional area of the air outlet is reduced when the back cylinder hole is closed, namely R is reduced, F (square meter) is correspondingly reduced, and Q (m) ³ The wind speed V (m/s) becomes larger when the value of/h) is unchanged, and clothes can be better blown away when the wind speed is increased, so that the clothes are stretched. Meanwhile, the cross-sectional area of the air outlet is reduced, so that the air stays in the cylinder for a longer time, the stirring force of the wind field is enhanced, and the smoothness of clothes is improved.

When clothes made of different materials are dried, each clothes fabric has a specific optimal wrinkle-removing water content interval, and when different clothes reach the optimal wrinkle-removing water content interval during drying, holes on the rear cylinder wall are closed in a corresponding time period to start the optimal wrinkle-removing stage of the clothes.

TABLE 1

Nursing program mode	Optimal wrinkle-removing moisture content
		Cotton and hemp	10％-26％
Chemical fiber	20％-28％
		Wool	10％-21％
Silk fabric	10％-35％
		Shirt	15％-23％
Western-style clothes	5％-6％
		Mink skin	10％-15％

Table 1 shows the optimal wrinkle-removing water content for different materials of clothing. Each fabric has unique properties for cotton, hemp, chemical fiber, wool, silk, shirt, western-style clothes and mink skin. The cotton and hemp materials are easy to absorb water and are thick and heavy. Chemical fiber materials are not easy to absorb water and easy to lose water. Wool materials are difficult to absorb water and lose water, and a long time is required. The silk material is lighter and thinner, and the better throwing state and flatness effect can be achieved only by higher water content. The shirt has larger volume and needs larger water content to remove wrinkles better. The overall shape of the western-style clothes is harder, the western-style clothes are relatively firm and are not suitable for absorbing water, but a relatively good wrinkle removing effect can be achieved by using a relatively low water content. Mink skin requires a moderate moisture content to smooth and shiny hair and to promote flatness. Therefore, as a whole, according to the results of the related experiments, cotton and hemp materials adopt a wrinkle-removing water content interval of 10% -26%, chemical fiber materials adopt a wrinkle-removing water content interval of 20% -28%, wool materials adopt a wrinkle-removing water content interval of 10% -21%, silk materials adopt a wrinkle-removing water content interval of 10% -35%, shirt materials adopt a wrinkle-removing water content interval of 15% -23%, western-style clothes materials adopt a wrinkle-removing water content interval of 5% -6%, and mink skin materials adopt a wrinkle-removing water content interval of 10% -15%.

Because of the characteristics of each clothing material, the water loss rate during drying is different, and the time for reaching the optimal wrinkle-removing water content interval is also different. When the water content of each clothes is up to the optimal wrinkle-removing water content interval, the holes on the rear cylinder wall can be closed to open the optimal clothes wrinkle-removing stage.

In the prior art, a drying mode is not adjusted according to the optimal wrinkle-removing water content of different clothes materials in the clothes drying process, each material fabric can have the optimal wrinkle-removing water content, and the opening and closing of the holes on the rear cylinder wall in the washing inner cylinder are controlled by judging whether the water content reaches the wrinkle-removing water content, so that the change of an air outlet state can be achieved, different movement states of the clothes in the cylinder can be controlled, and the flatness of the dried clothes can be improved for the clothes with different materials.

In order to further improve the drying effect, the control device is also used for controlling the rotation-stop ratio of the rotary drum in different drying stages, wherein the rotary drum is controlled to operate according to a first rotation-stop ratio in a rapid dehumidification stage, and the rotary drum is controlled to operate according to a second rotation-stop ratio in a wrinkle removal stage; the first rotation stop ratio is smaller than the second rotation stop ratio. The first stage is a rapid dehumidification stage, the holes of the rear drum wall are kept in an open state, and the second stage is an optimal clothes wrinkle removing stage, and the holes of the rear drum wall are kept in a closed state. In the first stage, the water content of clothes is higher, the load weight is larger, and the stop time is controlled to be not less than 12.5% of the rotation time but not more than 50% of the rotation time in the inner drum rotation stop rhythm in order to prevent larger abrasion; in the second stage, the wind speed in the drum is increased, the stirring force of the wind field is increased, so that the inner drum can rotate continuously in order to better achieve the ideal throwing state of clothes, the stop time in the rotating and stopping rhythm is generally not more than 1.6% of the rotation time, the water content is relatively low in the period, and the clothes are not worn too much.

The intelligent degree of the washing machine is high, the motion state of clothes in the inner cylinder can be effectively improved, and clothes with different materials can achieve good flatness after drying.
