[0047] The initial water content of the load in the barrel is obtained; this stage is to obtain the current internal water content of the clothing to be cared for in the barrel.

[0048] The steam care process is determined according to the clothing category of the load in the barrel, the optimal water content range for steam ironing, and the initial water content.

[0049] Determining the steam care process according to the clothing category of the load in the barrel, the optimal water content for steam ironing, and the initial water content includes: implementing a multi-stage steam care process on the load in the barrel according to the clothing category of the load in the barrel, the optimal water content range for steam ironing, and the initial water content, and providing steam temperatures that meet the needs of different stages for different stages.

[0050] Implementing a multi-stage steam care process on the load in the barrel according to the clothing category of the load in the barrel, the optimal water content range for steam ironing, and the initial water content, and providing steam temperatures that meet the needs of different stages for different stages includes: estimating the total steam supply time, the steam supply temperature amplitude range according to the clothing category of the load in the barrel, the optimal water content range for steam ironing, and the initial water content.

[0051] Implementing a multi-stage steam care process on the load in the barrel according to the clothing category of the load in the barrel, the optimal water content range for steam ironing, and the initial water content, and providing steam temperatures that meet the needs of different stages for different stages also includes: setting the steam supply time, the steam supply temperature threshold range for each process stage according to the estimated total steam supply time, the steam supply temperature amplitude range.

[0052] The steam care process also includes:

[0053] According to the steam supply time, the steam supply temperature threshold range of each supply stage, the steam temperature in the barrel is gradually increased by stage;

[0054] The temperature in the barrel is monitored in real time, and when the temperature in the barrel exceeds the maximum threshold of the steam supply temperature threshold range of the current process stage, the fan is started to cool the barrel.

[0055] The fan selects different wind speeds according to different steam temperatures required in different stages of ironing.

[0056] The steam care stage includes three process stages, wherein:

[0057] The preset duration of the first process stage is t1;

[0058] The duration of the second process stage is t2;

[0067] The temperature rising speed of the third stage is ΔT3 / t3;

[0068] Wherein, ΔT3 / t3>ΔT1 / t1>ΔT2 / t2.

[0069] In the second process stage, the current moisture content of the load in the drum is detected in real time, and when the current moisture content is within the optimal moisture content range for steam ironing, the second process stage is stopped and the third process stage is entered.

[0070] In the second process stage, when the current moisture content falls within the optimal moisture content range for steam ironing, and the second process stage does not reach the preset duration t2, the second process stage is forcibly stopped and the third process stage is entered;

[0071] The third process stage is to quickly raise the temperature in the high drum, and preheat the required temperature in the drying care stage.

[0072] When the second process stage reaches the preset duration t2 but the current moisture content does not fall within the optimal moisture content range for steam ironing, the second process stage is continued.

[0073] In this way, different types of clothes can be subjected to steam care at different steam temperatures in the corresponding stages, so that the internal tissue fibers of different types of clothes can always reach an optimal relaxation state during ironing, reducing damage to the internal tissue fibers of the clothes. This can keep the clothes in an optimal care state and prevent irreversible shrinkage and hardening of the clothes caused by denaturation of the traditional high temperature.

[0074] The steam temperature required for different stages of clothes fabric care is as follows:

[0075] The steam temperature for silk in the first stage of ironing is 40-50°C, the steam temperature in the second stage is 50-90°C, and the steam temperature in the third stage is 90°C;

[0076] The steam temperature for wool in the first stage of ironing is 40-50°C, the steam temperature in the second stage is 60-80°C, and the steam temperature in the third stage is 80°C;

[0078] The steam temperature for cotton and linen in the first stage of ironing is 40-50°C, the steam temperature in the second stage is 70-100°C, and the steam temperature in the third stage is 100°C;

[0079] The steam temperature for shirts in the first stage of ironing is 40-50°C, the steam temperature in the second stage is 70-90°C, and the steam temperature in the third stage is 90°C;

[0080] The steam temperature for suits in the first stage of ironing is 40-50°C, the steam temperature in the second stage is 90-100°C, and the steam temperature in the third stage is 100°C.

[0081] Drying care stage;

[0082] When the steam care process completes the third stage, it enters the drying care stage;

[0083] In the drying care stage, the drying temperature, barrel speed, and rotation-to-stop ratio are controlled according to the type of clothes in the barrel.

[0084] The drying care stage includes at least two drying stages before and after; it includes determining the total drying time of the clothes according to the type of clothes, and determining the first drying stage in the early drying period and the second stage in the late drying period according to the total drying time.

[0085] The drying temperatures used by different clothes in the two drying stages before and after are as follows:

[0086] The drying temperature of silk in the two drying stages is 37-45℃.

[0087] The drying temperature of wool in the two drying stages is 37-45℃.

[0088] The drying temperature of chemical fiber in the two drying stages is 45-55℃.

[0089] The drying temperature of cotton and hemp in the two drying stages is 40-60℃.

[0090] The drying temperature of shirt in the two drying stages is 45-55℃.

[0091] The drying temperature of suit in the two drying stages is 45-55℃.

[0092] In the early drying stage, the drum is controlled to rotate at a first rotating speed n1 and a first rotating stopping ratio K1;

[0093] In the late drying stage, the drum is controlled to rotate at a second rotating speed n2 and a second rotating stopping ratio K2;

[0094] n1≦n2, K1≦K2.

[0095] Wherein, the rotating speed and rotating stopping ratio in the first drying stage in the early drying stage and the second stage in the late drying stage according to the clothes category are as follows:

[0096] The rotating speed of silk in the first stage is 45rpm, and the rotating stopping ratio is 58 / 2; the rotating speed in the second stage is 55rpm, and the rotating stopping ratio is 60 / 0.

[0097] The rotating speed of wool in the first stage is 35rpm, and the rotating stopping ratio is 2 / 28; the rotating speed in the second stage is 75rpm, and the rotating stopping ratio is 118 / 2.

[0098] The rotating speed of chemical fiber in the first stage is 45rpm, and the rotating stopping ratio is 55 / 5; the rotating speed in the second stage is 55rpm, and the rotating stopping ratio is 55 / 5.

[0101] The rotating speed of suit in the first stage is 40rpm, and the rotating stopping ratio is 115 / 5; the rotating speed in the second stage is 40rpm, and the rotating stopping ratio is 115 / 5.

[0102] The rotation-to-stop ratio is the ratio of the rotation time to the stop time. The value of the rotation speed and the rotation-to-stop ratio in the later stage is greater than or equal to the value in the earlier stage.

[0103] The purposes of the above settings are twofold: in the early stage of drying, the clothes are quickly dehumidified after ironing, reducing the wear and hardening of the fabric caused by mechanical force in the stretched state. In the later stage of drying, the clothes are mainly de-wrinkled, and a high rotation speed and rotation-to-stop ratio are required to throw the clothes around in the drum.

[0104] The above settings can fully improve the drying effect of the clothes, thereby reducing the wear, pilling, and other phenomena caused by large mechanical force, and improving the user experience.
