Description
Technical Field
[0001] The present application relates to the field of clothing processing equipment, and in particular, to a control method, an electronic device and a clothing processing equipment. Background Art
[0002] When using a drum washing machine with a drying function, accurately judging whether the drying is complete has always been a goal that technicians in this field have been committed to achieving perfection. When executing the drying judgment stage in the drying stage, the existing drum washing machine with a drying function usually needs to obtain the temperature values of different positions in the inner drum through a temperature sensing bag, and judge whether the clothes in the drum are dried according to the temperature difference at different positions. The change in the water content of the clothes is judged by the temperature difference at different positions, and further judged whether the clothes are dried. However, during the drying process, the clothes may become tangled, entangled, or large pieces of clothes may wrap around other clothes, which will cause uneven drying of the clothes. At this time, the judgment of the water content of the clothes is not accurate enough, and it is difficult to accurately judge whether the clothes are dried, which may easily lead to excessive drying time and damage to the clothes, or cause the drying time to be too short and the clothes are not dried. Summary of the invention

[0016] Optionally, the method further comprises:
[0017] According to the weight M, operating parameters of the washing tub in the second control process are controlled.
[0018] Optionally, when the weight M is within a first preset range, in the second control process, the washing tub is periodically operated within a first time period with a first cycle as a sub-cycle, and in the first cycle, the washing tub rotates along a first direction at a first speed, then rotates along the first direction at a second speed, and finally rotates along a second direction at the second speed;
[0019] When the weight M is within the second preset range, in the second control process, the washing tub is periodically operated in a second time period with the second cycle as a sub-cycle, and in the second cycle, the washing tub rotates along the first direction at the third speed, and then rotates along the second direction at the third speed;
[0020] Among them, the weights of the first preset range and the second preset range increase successively, the first speed is greater than the third speed, the third speed is greater than the second speed, the first direction and the second direction are opposite, and the duration of the first time period is greater than the duration of the second time period.

[0026] According to a second aspect of an embodiment of the present application, an electronic device is provided, comprising a memory and a processor, wherein the memory is used to store a computer program; and the processor is used to execute the computer program to implement the steps of the control method described in any one of the above claims.
[0027] According to a third aspect of an embodiment of the present application, a clothing processing device is provided, wherein the clothing processing device has a drying function, and the clothing processing device is used to execute any one of the control methods described above, or includes the electronic device described above.
[0028] The solution provided by the present invention has the following beneficial effects compared with the prior art:
[0029] Through the above technical solution, according to the weight M, the running time T and the running time T1, it can be judged whether the clothes in the washing tub have been dehumidified. Further, according to whether the clothes have been dehumidified, it can be judged whether the clothes can be dried. When the clothes are not dehumidified in the dehumidification stage, the clothes still have a lot of moisture. At this time, the clothes processing equipment can be controlled to perform the second control process, that is, to control the operating parameters of the washing tub in the clothes processing equipment. The operating parameters here include the running time, the rotation direction and the rotation speed. When the operating parameters of the washing tub change, the state of the clothes will also change, and the contact area between the drying airflow and the clothes will be increased, so that the clothes can be dried in the second control process. By adjusting the operating parameters of the washing tub, the clothes can be further dehumidified until they are dried in the second control process. In the dry judgment stage, it is necessary to further judge whether the clothes in the washing tub are knotted, entangled, or whether large clothes wrap other clothes according to the eccentricity value N1 of the washing tub, that is, whether the clothes in the washing tub are abnormal clothes. When the clothes in the washing tub are abnormal, the abnormal degree of the abnormal clothes in the washing tub can be judged according to the size of the eccentricity value. For example, if the clothes are knotted and become abnormal clothes, the higher the abnormal degree of the abnormal clothes, the more serious the knotting of the clothes. If the eccentricity value N1 of the washing tub is normal, it means that the clothes in the washing tub are not abnormal clothes at this time. At this time, the clothes processing equipment is controlled not to perform the first control process and the second control process. The water content of the clothes can be accurately judged, and it can accurately judge whether the clothes are dried. The clothes processing equipment can perform the dry judgment stage normally. When the eccentricity value N1 of the washing tub is slightly larger, it means that the abnormal degree of the abnormal clothes in the washing tub is normal. At this time, it is necessary to control the clothes processing equipment to perform the first control process, that is, insert the dehydration stage and the shaking stage in sequence in the dry judgment stage. The dehydration stage can destroy the state of the abnormal clothes in the washing tub, and the abnormal clothes are easier to shake apart. The execution of the shaking stage can further shake the abnormal clothes apart, and further destroy the state of the abnormal clothes in the washing tub. After destroying the state of the abnormal clothes, the contact area between the drying airflow and the clothes can be increased to ensure the accuracy of judging whether the clothes are dried by the water content in the dry judgment stage. When the eccentricity value N1 is too large, it means that there are abnormal clothes in the washing tub at this time. When the abnormality is high, it is difficult to adjust and destroy the state of abnormal clothes through the dehydration stage and the shaking stage. At this time, it is difficult to ensure the accuracy of judging whether the clothes are dried by the water content in the dry judgment stage. At this time, the clothes processing equipment can be directly controlled to perform the second control process, that is, to control the operating parameters of the washing tub in the clothes processing equipment. The operating parameters here include the operating time, the rotation direction and the rotation speed. By adjusting the operating parameters of the washing tub, the area of the clothes drying airflow entering the clothes can be increased, so that the clothes can be dried evenly during the second control process, and it is no longer necessary to detect whether the clothes are dried, so as to avoid the damage of the clothes due to too long drying time or the failure of the clothes to be dried due to too short drying time due to inaccurate detection.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0037] It should be understood that the "multiple" mentioned herein refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.
[0038] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.
[0039] Generally speaking, when a drum washing machine with a drying function is in use, it can obtain a preset drying stage running time according to the weight of the clothes to be dried. The drying stage usually includes a dehumidification stage and a drying judgment stage. In the dehumidification stage, drying airflow will continuously enter the washing tub, and the heating element in the clothes processing equipment will start to gradually heat the drying airflow until it is stable. The temperature in the washing tub will gradually increase and dry the clothes. The moisture on the clothes is gradually dried as the temperature in the washing tub gradually increases. When it is detected that the moisture content of the clothes in the washing tub is lower than a certain value, the clothes processing equipment enters the drying judgment stage from the dehumidification stage. In the drying judgment stage, the clothes processing equipment will determine when to stop the drying stage.
[0040] According to a first aspect of the embodiment of the present disclosure, Figures 1 to 5 As shown, a control method is provided for a clothes processing device with a drying function, the clothes processing device having a washing tub for accommodating clothes, and the control method comprises:
[0041] Step S100: Obtain the preset running time T1 of the drying stage according to the weight M of the clothes to be dried. When the clothes are heavier, the overall moisture content of the clothes is higher, which means that the preset running time T1 of the drying stage is longer; when the clothes are lighter, the overall moisture content of the clothes is lower, which means that the preset running time T1 of the drying stage is shorter.
[0042] Step S200: Control the clothes treatment device to execute the dehumidification stage in the drying stage. After the dehumidification stage is executed, obtain the running time T of the dehumidification stage. Generally speaking, the drying stage includes a dehumidification stage and a drying stage which are executed in sequence. In the dehumidification stage, the drying airflow will continuously enter the washing tub, and the heating element in the clothes treatment device will start, gradually heating the drying airflow until it is stable. The temperature in the washing tub will gradually increase and dry the clothes. The moisture on the clothes will gradually be dried as the temperature in the washing tub gradually increases. When it is detected that the moisture content of the clothes in the washing tub is lower than a certain value, the clothes treatment device is controlled to enter the drying stage from the dehumidification stage. In the drying stage, the clothes treatment device can determine when to stop the drying stage. By obtaining the running time T of the dehumidification stage, it can be determined whether the running speed of the dehumidification stage is long enough.
[0043] Step S300: According to the weight M, the running time T and the running time T1, the clothes processing device is controlled to selectively perform the second control process or the clothes processing device is controlled to perform the dryness judgment stage in the drying stage. According to the weight M, the running time T and the running time T1, it can be judged whether the clothes in the washing tub are dehumidified. Further, it can be judged whether the clothes can be dried by whether the clothes are dehumidified. If the weight M is within a certain range and the running time T and the running time T1 are abnormal, it means that the clothes in the washing tub are knotted, entangled, or large clothes are wrapped around other clothes, etc., and the clothes are not dehumidified in the dehumidification stage, and the clothes still have a lot of moisture. At this time, it is necessary to control the clothes processing device to perform the second control process, that is, to control the operating parameters of the washing tub in the clothes processing device. The operating parameters here include the operating time, the rotation direction and the rotation speed. When the operating parameters of the washing tub change, the state of the clothes will also change, and the contact area between the drying airflow and the clothes will be increased, so that the clothes can be dried in the second control process. By adjusting the operating parameters of the washing tub, the clothes can be further dehumidified until they are dried in the second control process. In this way, the problem of inaccurate judgment based on the moisture content of the clothes when judging whether to end the dehumidification stage and enter the drying stage is avoided. The clothing processing equipment will not enter the drying stage too early, which avoids the clothes not being dried completely due to the drying time being too short. At the same time, when the clothes are not dehumidified, the second control processing can be used to further dehumidify the clothes until the drying is completed during the second control processing, so that the clothes can be dried even if the dehumidification is not completed.
[0044] Step S400: During the execution of the dry judgment stage, according to the eccentricity value N1 of the washing tub, the clothes processing device is controlled to selectively perform the first control process and the second control process, wherein the first control process includes controlling the clothes processing device to sequentially insert the dehydration stage and the shaking stage in the dry judgment stage, and the second control process includes controlling the operating parameters of the washing tub in the clothes processing device to loosen the clothes, and the operating parameters include the operating time, rotation direction and rotation speed of the washing tub. When the weight M is within a certain range and the operating time T and the operating time T1 are abnormal, it is necessary to control the clothes processing device to perform the second control process. On the contrary, when the weight M is not within a certain range but the operating time T and the operating time T1 are abnormal, or when the weight M is within a certain range but the operating time T and the operating time T1 are normal, it is necessary to control the clothes processing device to execute the dry judgment stage. In the dry judgment stage, it is necessary to further judge whether the clothes in the washing tub are knotted, entangled or whether the large clothes wrap other clothes according to the eccentricity value N1 of the washing tub, that is, whether the clothes in the washing tub are abnormal clothes. When the clothes in the washing tub are abnormal, the abnormal degree of the abnormal clothes in the washing tub can be judged according to the size of the eccentricity value. For example, if the clothes are knotted and become abnormal clothes, the higher the abnormal degree of the abnormal clothes, the more serious the knotting of the clothes. If the eccentricity value N1 of the washing tub is normal, it means that the clothes in the washing tub are not abnormal clothes at this time. At this time, the clothes processing equipment is controlled not to perform the first control process and the second control process. The water content of the clothes can be accurately judged, and it can accurately judge whether the clothes are dried. The clothes processing equipment can perform the dry judgment stage normally. When the eccentricity value N1 of the washing tub is slightly larger, it means that the abnormal degree of the abnormal clothes in the washing tub is normal. At this time, it is necessary to control the clothes processing equipment to perform the first control process, that is, insert the dehydration stage and the shaking stage in sequence in the dry judgment stage. The dehydration stage can destroy the state of the abnormal clothes in the washing tub, and the abnormal clothes are easier to shake apart. The execution of the shaking stage can further shake the abnormal clothes apart, and further destroy the state of the abnormal clothes in the washing tub. After destroying the state of the abnormal clothes, the contact area between the drying airflow and the clothes can be increased to ensure the accuracy of judging whether the clothes are dried by the water content in the dry judgment stage. When the eccentricity value N1 is too large, it means that there are abnormal clothes in the washing tub and the abnormality is high. At this time, it is difficult to adjust and destroy the state of the abnormal clothes through the dehydration stage and the shaking stage. At this time, it is difficult to ensure the accuracy of judging whether the clothes are dried by the water content in the drying stage.At this time, the clothing processing equipment can be directly controlled to perform the second control processing, that is, to control the operating parameters of the washing tub in the clothing processing equipment. By adjusting the operating parameters of the washing tub, the area of the clothing drying airflow entering the clothing can be increased, so that the clothing can be dried evenly during the second control processing, and there is no need to detect whether the clothing is dried, thereby avoiding damage to the clothing due to too long drying time or failure to dry the clothing due to too short drying time due to inaccurate detection.
[0045] Through the above technical solution, according to the weight M, the running time T and the running time T1, it can be judged whether the clothes in the washing tub have been dehumidified. Further, according to whether the clothes have been dehumidified, it can be judged whether the clothes can be dried. When the clothes are not dehumidified in the dehumidification stage, the clothes still have a lot of moisture. At this time, the clothes processing equipment can be controlled to perform the second control process, that is, to control the operating parameters of the washing tub in the clothes processing equipment. The operating parameters here include the running time, the rotation direction and the rotation speed. When the operating parameters of the washing tub change, the state of the clothes will also change, and the contact area between the drying airflow and the clothes will be increased, so that the clothes can be dried in the second control process. By adjusting the operating parameters of the washing tub, the clothes can be further dehumidified until they are dried in the second control process. In the dry judgment stage, it is necessary to further judge whether the clothes in the washing tub are knotted, entangled, or whether large clothes wrap other clothes according to the eccentricity value N1 of the washing tub, that is, whether the clothes in the washing tub are abnormal clothes. When the clothes in the washing tub are abnormal, the abnormal degree of the abnormal clothes in the washing tub can be judged according to the size of the eccentricity value. For example, if the clothes are knotted and become abnormal clothes, the higher the abnormal degree of the abnormal clothes, the more serious the knotting of the clothes. If the eccentricity value N1 of the washing tub is normal, it means that the clothes in the washing tub are not abnormal clothes at this time. At this time, the clothes processing equipment is controlled not to perform the first control process and the second control process. The water content of the clothes can be accurately judged, and it can accurately judge whether the clothes are dried. The clothes processing equipment can perform the dry judgment stage normally. When the eccentricity value N1 of the washing tub is slightly larger, it means that the abnormal degree of the abnormal clothes in the washing tub is normal. At this time, it is necessary to control the clothes processing equipment to perform the first control process, that is, insert the dehydration stage and the shaking stage in sequence in the dry judgment stage. The dehydration stage can destroy the state of the abnormal clothes in the washing tub, and the abnormal clothes are easier to shake apart. The execution of the shaking stage can further shake the abnormal clothes apart, and further destroy the state of the abnormal clothes in the washing tub. After destroying the state of the abnormal clothes, the contact area between the drying airflow and the clothes can be increased to ensure the accuracy of judging whether the clothes are dried by the water content in the dry judgment stage. When the eccentricity value N1 is too large, it means that there are abnormal clothes in the washing tub at this time. When the abnormality is high, it is difficult to adjust and destroy the state of abnormal clothes through the dehydration stage and the shaking stage. At this time, it is difficult to ensure the accuracy of judging whether the clothes are dried by the water content in the drying stage. At this time, the clothes processing equipment can be directly controlled to perform the second control process, that is, the operating parameters of the washing tub in the clothes processing equipment are controlled. By adjusting the operating parameters of the washing tub, the area of the clothes drying airflow entering the clothes can be increased, so that the clothes can be dried evenly during the second control process, and it is no longer necessary to detect whether the clothes are dried, so as to avoid the damage of the clothes due to too long drying time or the failure of the clothes to be dried due to too short drying time due to inaccurate detection.
[0046] The operation parameters may include the operation time, rotation direction and rotation speed of the washing tub, so that the second control process loosens the clothes in the washing tub. In this way, by adjusting the operation time, rotation direction and rotation speed of the washing tub, the clothes in the washing tub can be loosened, and the area of the clothes drying airflow entering the clothes can be further increased, so that the clothes can be dried evenly during the second control process, and it is no longer necessary to detect whether the clothes are dried, so as to avoid the damage of the clothes due to too long drying time or the failure of the clothes to be dried due to too short drying time due to inaccurate detection.
[0047] Specifically, when the eccentricity value N1 is greater than or equal to the first preset value and less than the second preset value, the first control processing can be performed on the clothing processing device; when the eccentricity value N1 is greater than or equal to the second preset value, the second control processing can be performed on the clothing processing device, wherein the second preset value is greater than the first preset value.
[0048] When the eccentricity value N1 is greater than or equal to the first preset value and less than the second preset value, it means that the abnormal degree of abnormal clothes in the washing tub is normal. At this time, it is necessary to control the clothes processing device to perform the first control process, that is, insert the dehydration stage and the shaking stage in sequence in the dry judgment stage. The dehydration stage can destroy the state of the abnormal clothes in the washing tub, and the abnormal clothes are more likely to be shaken apart. The execution of the shaking stage can further shake the abnormal clothes apart, and further destroy the state of the abnormal clothes in the washing tub. Destroying the state of the abnormal clothes can ensure the accuracy of judging whether the clothes are dried in the dry judgment stage. When the eccentricity value N1 is greater than or equal to the second preset value, it means that the abnormal degree of abnormal clothes in the washing tub is high. At this time, it is difficult to adjust the abnormal degree of abnormal clothes through the dehydration stage and the shaking stage. At this time, the clothes processing device can be controlled to perform the second control process. By adjusting the operating parameters of the washing tub, the clothes can be dried evenly during the second control process, ensuring the accuracy of judging whether the clothes are dried in the dry judgment stage. Correspondingly, when the eccentricity value N1 is less than the first preset value, it indicates that the clothes in the washing tub are not abnormal clothes. At this time, the clothes processing device is controlled not to perform the first control process and the second control process, and the clothes processing device can execute the dryness judgment stage normally.
[0049] Taking a clothing processing device with a drying function as an example, the operating parameters of the washing tub here refer to the rotation direction and rotation speed of the washing tub. Through the rotation direction and rotation speed of the washing tub, the clothes can be dried evenly in the second control process, ensuring the accuracy of judging whether the clothes are dried in the second control process.
[0050] The control method in the present application may also include step 500: after controlling the clothing processing device to perform the first control process, the eccentricity value N2 of the washing tub is obtained, and according to the eccentricity value N2, the clothing processing device is controlled to selectively perform the second control process. According to the eccentricity value N2, it can be judged whether the state of the clothing in the washing tub is still abnormal or restored to normal after the first control process. If the eccentricity value N2 is still too large, it means that the abnormal degree of the abnormal clothing in the washing tub is still high at this time. At this time, the clothing processing device can be controlled to perform the second control process, so that the clothing can be dried evenly in the second control process, ensuring the accuracy of judging whether the clothing is dried in the second control process.
[0051] Specifically, when the eccentricity value N2 is greater than or equal to the first preset value, the clothes processing device is controlled to perform the second control process. When the eccentricity value N2 is greater than or equal to the first preset value, it means that the abnormal degree of the abnormal clothes in the washing tub is still high at this time. At this time, the clothes processing device can be controlled to perform the second control process, so that the clothes can be dried evenly in the second control process, ensuring the accuracy of judging whether the clothes are dried in the second control process. Correspondingly, when the eccentricity value N2 is less than the first preset value, it means that the abnormal clothes in the washing tub have been restored from the abnormal state to the normal state at this time, and the clothes processing device can continue to perform the dry judgment stage normally.
[0052] In the present application, when obtaining the eccentricity value N1 and the eccentricity value N2, the eccentricity values of the washing tubs may be detected multiple times to ensure the accuracy of obtaining the eccentricity values N1 and N2. For example, when obtaining the eccentricity value N1, the eccentricity value may be detected once per second within a certain period of time, such as 5 seconds, to obtain five eccentricity values. At this time, the average value of the five eccentricity values may be taken as the eccentricity value N1 to ensure the accuracy of the eccentricity value detection, and the same is true when obtaining the eccentricity value N2.
[0053] In some implementations, the control method may further include step S600: controlling the operating parameters of the washing tub in the second control process according to the weight M. When the clothes processing device is controlled to perform the second control process, the operating parameters of the washing tub in the clothes processing device are controlled to ensure the accuracy of detecting whether the clothes are dried in the drying judgment stage. At this time, the weight M of the clothes to be dried can be obtained. When the weight M of the clothes to be dried is different, the operating parameters of the washing tub in the second control process are also different, so that clothes of different weights are dried evenly in the second control process, further ensuring the accuracy of judging whether the clothes are dried, and avoiding the problem of difficulty in accurately judging whether the clothes are dried, which easily leads to excessive drying time and damage to the clothes.
[0054] Specifically, when the weight M is within the first preset range, in the second control process, the washing tub takes the first cycle as a sub-cycle and runs periodically within the first time period. In the first cycle, the washing tub rotates along the first direction at a first speed, then rotates along the first direction at a second speed, and finally rotates along the second direction at a second speed; when the weight M is within the second preset range, in the second control process, the washing tub takes the second cycle as a sub-cycle and runs periodically within the second time period. In the second cycle, the washing tub rotates along the first direction at a third speed, and then rotates along the second direction at a third speed; wherein the weights of the first preset range and the second preset range increase successively, the first speed is greater than the third speed, the third speed is greater than the second speed, the first direction and the second direction are in opposite directions, and the duration of the first time period is greater than the duration of the second time period.
[0055] Taking the actual use of a drum washing machine with a drying function as an example, since the weight in the first preset range is less than the weight in the second preset range, the first preset range here may refer to the weight range of clothes in the case of a small amount of clothes, and the second preset range may refer to the weight range of clothes in the case of a medium amount of clothes and a large amount of clothes. When the weight M is within the first preset range, it means that there is a small amount of clothes in the washing tub at this time. At this time, the washing tub can be operated periodically in the first time period with the first cycle as a sub-cycle. In the first cycle, the washing tub rotates along the first direction at a first speed, so that the clothes in the washing tub in an abnormal state can stick to the wall, and a cavity will be formed inside the washing tub. At this time, the clothes that have been dried on the outside can stick to the wall, and the clothes that have not been dried on the inside of the clothes form the inner wall of the cavity, so that the drying airflow can dry the inside of the clothes through the cavity, so that both the outside and the inside of the clothes can be dried. The washing tub is then rotated along the first direction at the second speed. In this way, since the first speed is greater than the second speed, when the washing tub changes from the first speed to the second speed, the centrifugal force between the clothes will be reduced. At this time, the clothes will still be in the wall-adhering stage, but due to the reduction of centrifugal force, gaps will be generated between the clothes. In this way, the drying airflow can pass through the gaps and enter between the clothes, so that the clothes can be dried evenly after the second control treatment, and then rotated along the second direction at the second speed. By adjusting the rotation direction of the washing tub, the inertia when changing the rotation direction of the washing tub will further increase the size of the gaps generated between the clothes, and will also increase the number of gaps generated between the clothes, further allowing a small amount of clothes to be dried evenly in an abnormal state during the second control treatment. At the same time, during the second control treatment, the clothes processing device will also detect whether the clothes have been dried. When the abnormal clothes can be dried evenly during the second control treatment, the accuracy of the clothes processing device in judging whether the clothes have been dried is further ensured.
[0056] When the weight M is within the second preset range, it means that there are medium or large amounts of clothes in the washing tub. At this time, the washing tub can be operated periodically in the second time period with the second cycle as a sub-cycle. In the second cycle, the washing tub can rotate along the first direction at the third speed. When the washing tub rotates along the first direction at the third speed, the clothes are subjected to centrifugal force, and gaps are generated between the clothes. In this way, the drying airflow can enter between the clothes through the gaps, so that the clothes can be dried evenly in the second control process. The washing tub rotates along the second direction at the third speed again. By adjusting the rotation direction of the washing tub, the inertia when changing the rotation direction of the washing tub will further increase the size of the gaps generated between the clothes, and will also increase the number of gaps generated between the clothes, so that the medium or large amount of clothes can be dried evenly in the second control process under abnormal conditions. Compared with a small amount of clothes, when there are medium or large amounts of clothes, there are more clothes in the washing tub. At this time, even if the rotation speed of the washing tub is increased, the clothes cannot be attached to the wall and a cavity cannot be formed in the washing tub. Therefore, the third speed is less than the first speed, which can save energy while ensuring that the clothes can be generated by centrifugal force.
[0057] In addition, as described above, in the dehumidification stage, the drying airflow will continuously enter the washing tub, the heating element in the clothing treatment device will start, gradually heating the drying airflow until it is stable, the temperature in the washing tub will gradually increase and dry the clothes, and the moisture on the clothes will gradually be dried as the temperature in the washing tub gradually increases. When there are fewer clothes, the proportion of clothes relative to the washing tub is smaller, and the drying airflow heats the washing tub more. Therefore, in the dehumidification stage and when there are fewer clothes, the overall running time of the drying stage is shorter, but the time that the clothes can be heated and dried in the dehumidification stage is less. Therefore, when the clothing treatment device is controlled to perform the second control process and the clothes are a small amount of clothes, the duration of the second control process can be appropriately increased at this time, that is, after the clothing treatment device has detected that the clothes are dried, the second control process can continue to run for a period of time to ensure that a small amount of clothes can be dried, that is, the duration of the first time period can be greater than the duration of the second time period.
[0058] When the washing tub changes from the first speed to the second speed, the centrifugal force between the clothes will decrease. At this time, the clothes will still be in the wall-adhering stage, but due to the reduction of centrifugal force, gaps will be generated between the clothes, so that the drying airflow can pass through the gaps and enter between the clothes, so that the clothes can be dried evenly in the second control treatment, and then rotate at the second speed along the second direction. By adjusting the rotation direction of the washing tub, the inertia when changing the rotation direction of the washing tub will further increase the size of the gaps generated between the clothes, and will also increase the number of gaps generated between the clothes, further allowing a small amount of clothes to be dried evenly in the second control treatment under abnormal conditions. At the same time, in the second control treatment, the clothes processing device will also detect whether the clothes have been dried. When the abnormal clothes can be dried evenly in the second control treatment, it further ensures the accuracy of the clothes processing device in judging whether the clothes have been dried.
[0059] The larger the eccentricity value N1 is, the more serious the situation is that the clothes are tangled, entangled, or the large clothes are wrapped around other clothes. If the eccentricity value N1 is larger and the speed of the washing tub in the dehydration stage is higher, the clothes are more likely to stick to the wall, and the state of the clothes is not easy to change. Therefore, when the eccentricity value N1 is larger, the speed of the washing tub in the dehydration stage can be lower, so as to ensure the effect of destroying the state of the abnormal clothes in the washing tub in the second dehydration stage, so that the abnormal clothes are easier to shake out.
[0060] It should be noted that in the present application, the shaking stage of the clothing processing equipment is not limited. Depending on the different clothing processing equipment, the operating parameters of the washing tub are also different when shaking the clothes. In this regard, the present application does not make specific limitations, as long as the shaking program can shake the clothes after the dehydration stage.
[0061] In the control method of the present application, step S400 may include step S401: according to the weight M and the ratio interval to which T / T1 belongs, control the clothes processing device to selectively perform the second control process or control the clothes processing device to perform the dryness determination stage in the drying stage. As described above, according to the weight M of the clothes to be dried, a preset running time T1 of the drying stage can be obtained, where T1 includes the dehumidification time and the dryness determination time. After the dehumidification stage is executed, the running time T of the dehumidification stage can be directly obtained. Through the ratio interval of T / T1, it can be judged whether the clothes in the washing tub have enough time to be dehumidified in the dehumidification stage. When the ratio interval of T / T1 is large, it means that the dehumidification stage runs for a long enough time and the clothes in the washing tub have enough time to be dehumidified in the dehumidification stage. At this time, the water content of the clothes is judged normally, and the clothes processing equipment enters the dry judgment stage normally. When the ratio interval of T / T1 is small and if the weight M is within a certain range, it means that the clothes in the washing tub are abnormal clothes and the dehumidification stage runs for a short time. The clothes in the washing tub have not enough time to be dehumidified in the dehumidification stage, and the clothes are not dehumidified. At this time, controlling the clothes processing equipment to enter the dry judgment stage according to the water content of the clothes will cause the clothes processing equipment to enter the dry judgment stage prematurely when the clothes are not dehumidified.
[0062] Specifically, when the weight M is within the second preset range and the ratio interval to which T / T1 belongs is within the third preset range, the clothes processing device can be controlled to selectively perform the second control process. In the second control process, the washing tub takes the second cycle as a sub-cycle and runs periodically in the second time period. In the second cycle, the washing tub rotates along the first direction at the third speed, and then rotates along the second direction at the third speed. As described above, the second preset range can refer to the case of medium-sized clothes and a large amount of clothes, that is, when there are a lot of clothes. The numerical range of the third preset range can be smaller. When the ratio interval to which T / T1 belongs is within the third preset range, it means that the dehumidification stage runs for a short time, indicating that the clothes processing device enters the dry judgment stage too early. At this time, the clothes processing device needs to give priority to ensuring that the clothes are dried. At this time, the clothes processing device can be controlled to perform the second control process. In the second control process, the washing tub takes the second cycle as a sub-cycle and runs periodically in the second time period. In the second cycle, the washing tub rotates along the first direction at the third speed, and then rotates along the second direction at the third speed. In this way, the drying airflow can pass through the gap and enter between the clothes, so that the clothes can be dried evenly in the second control process, and the washing tub rotates at the third speed along the second direction. By adjusting the rotation direction of the washing tub, the inertia when changing the rotation direction of the washing tub will further increase the size of the gap between the clothes, and also increase the number of gaps between the clothes, so that the medium-sized clothes or a large amount of clothes can be dried evenly in the second control process when they enter the dry judgment stage in an abnormal state prematurely. Correspondingly, when the weight M is within the second preset range and the ratio interval to which T / T1 belongs is high, it means that the dehumidification stage has been running for a long enough time, and the clothes processing device has not entered the dry judgment stage prematurely. At this time, the clothes processing device can be controlled to continue to execute the dry judgment stage.
