Description

Technical Field

[0001] The present invention belongs to the technical field of clothing treatment, and particularly provides a dehydration control method for a clothing treatment device and a clothing treatment device. Background Art

[0002] When a clothing treatment device is drying clothes, if the clothes in the drum are unevenly distributed, the drum will vibrate during rotation. Excessive vibration will lead to hitting the drum or displacement of the clothing treatment device. At the same time, vibration will also generate noise, and when the vibration is severe, there is a risk of damaging the clothing treatment device or surrounding items.

[0003] In the prior art, to prevent the harm caused by vibration, before performing the drying operation, the clothes are distributed so that the clothes are evenly distributed in the drum. Clothes distribution means controlling the motor to rotate reversely at a low speed for a certain time first, and then rotate forward at a low speed for a certain time, so that the clothes are more evenly distributed around the circumference of the drum. During the clothes distribution process, the eccentricity value of the drum is detected (the eccentricity value is used to represent the amount by which the drum deviates from the central axis of the drum). If the eccentricity value is greater than the preset threshold, the clothes distribution continues until the detected eccentricity value is less than or equal to the preset threshold, and then the clothes distribution ends and the clothes drying process is entered.

[0004] However, when the clothes in the drum are single-piece or a small amount of clothes with particularly strong water absorption or are severely knotted, it is very difficult to evenly distribute the clothes in the drum through clothes distribution, and thus it is very difficult to reduce the eccentricity value, resulting in too long clothes distribution time, and then the washing program continues to run without ending, affecting the user experience.

[0005] Correspondingly, the art needs a new technical solution to solve the above practical problems. Summary of the Invention

[0006] The present invention aims to solve the above technical problems, that is, to solve the problem that when the clothes to be dehydrated are single-piece or a small amount of clothes with particularly strong water absorption or the clothes in the drum are severely knotted, it is very difficult to evenly distribute the clothes, resulting in the washing program not ending continuously and affecting the user experience.

[0007] In a first aspect, the present invention provides a dehydration control method for a clothing treatment device, the dehydration control method comprising the following steps: detecting an eccentricity value of a drum to obtain a first eccentricity value; comparing the first eccentricity value with a first preset eccentricity value; comparing the first eccentricity value with a second preset eccentricity value; and selectively executing a standard drying mode, a dynamic drying mode or ending the program according to the comparison result; wherein, when the dynamic drying mode is executed, the remaining time on the display screen is replaced with flashing dynamic characters.

[0008] In the preferred technical solution of the dehydration control method for the clothing treatment device described above, the step of "selectively executing the standard drying mode, the dynamic drying mode or ending the program according to the comparison result" specifically includes: if the first eccentricity value is not greater than the first preset eccentricity value, execute the standard drying mode; if the first eccentricity value is greater than the first preset eccentricity value and not greater than the second preset eccentricity value, execute the dynamic drying mode; if the first eccentricity value is greater than the second preset eccentricity value, end the program and give an alarm; wherein, the second preset eccentricity value is greater than the first preset eccentricity value.

[0009] In the preferred technical solution of the dehydration control method for the clothing treatment device described above, the step of "executing the dynamic drying mode" specifically includes: determining the dynamic drying rotation speed according to the first eccentricity value; performing drying for a set time according to the dynamic drying rotation speed; detecting the eccentricity value of the drum again to obtain the Nth eccentricity value, where N is the number of times of detecting the eccentricity value of the drum; comparing the Nth eccentricity value with the first eccentricity value; and judging whether to end the dynamic drying mode according to the comparison result.

[0010] In the preferred technical solution of the dehydration control method for the clothing treatment device described above, the step of "judging whether to end the dynamic drying mode according to the comparison result" specifically includes: if the Nth eccentricity value is less than the first eccentricity value, continue to execute the dynamic drying mode; if the Nth eccentricity value is not less than the first eccentricity value, end the program and give an alarm.

[0011] In the preferred technical solution of the dehydration control method for the clothing treatment device described above, the step of "continuing to execute the dynamic drying mode" specifically includes: comparing the Nth eccentricity value with the first preset eccentricity value; and judging whether to switch to the standard drying mode according to the comparison result.

[0012] In the preferred technical solution of the dehydration control method for the clothing treatment device described above, the step of "judging whether to switch to the standard drying mode according to the comparison result" specifically includes: if the Nth eccentricity value is not greater than the first preset eccentricity value, switch to the standard drying mode; if the Nth eccentricity value is greater than the first preset eccentricity value, do not switch to the standard drying mode and continue to execute the dynamic drying mode.

[0013] In the preferred technical solution of the dehydration control method for the clothing treatment device described above, the step of "not switching to the standard drying mode and continuing to execute the dynamic drying mode" specifically includes: on the basis of the dynamic drying speed during the previous drying, increasing the dynamic drying speed by one level; performing drying for a set time according to the new dynamic drying speed; and returning to the step of "detecting the eccentricity value of the drum again to obtain the Nth eccentricity value".

[0014] In the preferred technical solution of the dehydration control method for the clothing treatment device described above, when detecting the eccentricity value of the drum, the rotation speed of the drum is 100 rpm to 130 rpm; and / or, the standard drying speed in the standard drying mode is greater than the dynamic drying speed in the dynamic drying mode.

[0015] In the preferred technical solution of the dehydration control method for the clothing treatment device described above, the set time is 15 s to 30 s.

[0016] In a second aspect, the present invention provides a clothing treatment device, which includes a controller configured to be able to execute the dehydration control method for the clothing treatment device described above.

[0017] In the case of adopting the above technical solution, for the dehydration control method of the clothing treatment device of the present invention, the eccentricity value of the drum is detected to obtain a first eccentricity value, the first eccentricity value is compared with a first preset eccentricity value, the first eccentricity value is compared with a second preset eccentricity value, and according to the comparison results, the standard drying mode, the dynamic drying mode or the program is ended is selectively executed. Among them, when the dynamic drying mode is executed, the remaining time on the display screen is replaced with flashing dynamic characters; in such a setting method, by comparing the first eccentricity value with the first preset eccentricity value and the second preset eccentricity value, the clothing treatment device directly executes the standard drying mode or directly executes the dynamic drying mode or ends the program, so that it is possible to select a suitable program for operation according to the state of the clothes to be dehydrated in the drum, avoiding continuous operation in the case where the clothes cannot be distributed, so as to be able to end the washing program as soon as possible and improve the user experience; in addition, when the dynamic drying mode is executed, the remaining time on the display screen is replaced with flashing dynamic characters, which can indicate to the user that the dynamic drying mode is being executed, thus preventing the user from suspecting that the device is malfunctioning due to the long remaining time on the display screen or the remaining time on the display screen remaining unchanged, and improving the user experience.

[0018] Further, the second preset eccentricity value is greater than the first preset eccentricity value. The step of "selectively executing the standard spin-drying mode, the dynamic spin-drying mode or ending the program according to the comparison result" specifically includes: if the first eccentricity value is not greater than the first preset eccentricity value, the standard spin-drying mode is executed; if the first eccentricity value is greater than the first preset eccentricity value and not greater than the second preset eccentricity value, the dynamic spin-drying mode is executed; if the first eccentricity value is greater than the second preset eccentricity value, the program is ended. With such a setting method, when the first eccentricity value is not greater than the first preset eccentricity value, it indicates that the clothes are relatively evenly distributed in the drum, and the high-speed rotation and spin-drying of the drum will not cause damage to the equipment. The spin-drying can be directly carried out at a relatively high speed, and the standard spin-drying mode can be directly executed to quickly dehydrate and end the washing program. When the first eccentricity value is greater than the first preset eccentricity value and not greater than the second preset eccentricity value, it indicates that the clothes are unevenly distributed in the drum, but the eccentricity value of the drum can be reduced by spin-drying at a low speed for a period of time first, and then the eccentricity value of the drum can be further reduced by gradually increasing the spin-drying speed, so as to execute the dynamic spin-drying mode to change the spin-drying state in real time and spin-dry the clothes. When the first eccentricity value is greater than the second preset eccentricity value, it indicates that the drum will cause collisions as long as it rotates, which is likely to damage the equipment. At this time, the program is directly ended and an alarm is given to remind the user that the clothes have not been spin-dried, so that the user can manually re-arrange the clothes or wring them out before performing the dehydration operation again, or choose to directly air-dry them.

[0019] Still further, the step of "executing the dynamic spin-drying mode" specifically includes: determining the dynamic spin-drying speed according to the first eccentricity value; performing spin-drying for a set time according to the dynamic spin-drying speed; detecting the eccentricity value of the drum again to obtain the Nth eccentricity value; comparing the Nth eccentricity value with the first eccentricity value; and judging whether to end the dynamic spin-drying mode according to the comparison result. With such a setting method, first, the dynamic spin-drying speed is determined according to the first eccentricity value, and then spin-drying is performed for the set time according to the determined dynamic spin-drying speed to perform low-speed dehydration on the clothes to be dehydrated for the set time. Then, the eccentricity value of the drum is detected again to obtain the Nth eccentricity value, and it is judged whether the Nth eccentricity value is less than the first eccentricity value, and then whether to end the dynamic spin-drying mode is determined according to the judgment result.

[0020] Still further, the step of "judging whether to end the dynamic spin-drying mode according to the comparison result" specifically includes: if the Nth eccentricity value is less than the first eccentricity value, continue to execute the dynamic spin-drying mode; if the Nth eccentricity value is not less than the first eccentricity value, end the program and give an alarm. With such a setting method, if the Nth eccentricity value is not less than the first eccentricity value, it indicates that the low-speed dehydration cannot reduce the eccentricity value of the drum, so the clothes to be dehydrated are not suitable for the clothes treatment equipment to continue dehydration. At this time, the program is ended and an alarm is given so that the user can know that the clothes to be dehydrated have not been spin-dried and need to be air-dried.

[0021] Furthermore, the step of "continuing to execute the dynamic dehydration mode" specifically includes: comparing the Nth eccentricity value with the first preset eccentricity value, and judging whether to switch to the standard dehydration mode according to the comparison result. If the Nth eccentricity value is not greater than the first preset eccentricity value, switch to the standard dehydration mode; if the Nth eccentricity value is greater than the first preset eccentricity value, do not switch to the standard dehydration mode and continue to execute the dynamic dehydration mode. With such a setting method, by judging whether the Nth eccentricity value is greater than the first preset eccentricity value, it is selectively switched to the standard dehydration mode to quickly end the washing program.

[0022] Furthermore, the step of "not switching to the standard dehydration mode and continuing to execute the dynamic dehydration mode" specifically includes: on the basis of the dynamic rotation speed during the previous dehydration, increasing the dynamic dehydration rotation speed by one level, performing dehydration for a set time according to the new dynamic dehydration rotation speed, and returning to the step of "detecting the eccentricity value of the drum again to obtain the Nth eccentricity value". With such a setting method, the dynamic dehydration rotation speed is increased and dehydration is performed for a set time to further perform low-speed dehydration on the clothes to be dehydrated. Then, the eccentricity value of the drum is detected again, and further judgment is made according to the Nth eccentricity value. The clothes to be dehydrated are dehydrated by gradually increasing the dynamic dehydration rotation speed to gradually reduce the eccentricity value of the drum until the dynamic dehydration mode can be switched to the standard dehydration mode, so as to quickly end the washing program. At the same time, the eccentricity value of the drum is gradually reduced by using a stepped speed increase method, which will not cause damage to the equipment during the execution of the dynamic dehydration mode, and the operation is stable and the user experience is good.

[0023] Furthermore, when detecting the eccentricity value of the drum, the rotation speed of the drum is 100 rpm. At this low rotation speed, the measured eccentricity value is accurate and stable.

[0024] Furthermore, the set time is 15 s to 30 s. This dehydration time is appropriate, which can not only perform dehydration but also avoid the whole washing time being too long due to too long dehydration time, improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, in which:

[0026] Figure 1 is the main flowchart of the dehydration control method for the laundry treatment equipment of the present invention;

[0027] Figure 2 is the flowchart of the first embodiment of the dehydration control method for the laundry treatment equipment of the present invention;

[0028] Figure 3 is the flowchart of the second embodiment of the dehydration control method for the laundry treatment equipment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0030] It should be noted that in the description of the present invention, the terms "first", "nth" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] When the laundry to be dehydrated is a laundry with particularly strong water absorption (such as a sweater or a sponge), and the quantity is small, such as one piece, two pieces or three pieces, or when the laundry is particularly severely knotted, the eccentricity value of the drum is relatively large, and the distribution of the laundry is only changed by forward and reverse rotation to change the distribution state of the laundry, so that the laundry is evenly distributed around the circumference of the drum, thereby reducing the eccentricity value of the drum. However, in the above cases, even if the laundry distribution is performed, the water absorption state and the knotting situation of the laundry will not easily change, so it is very difficult to make the laundry evenly distributed and reduce the eccentricity value of the drum through the laundry distribution operation.

[0032] Based on the problem pointed out in the background technology that when the laundry to be dehydrated is a single piece or a small amount with particularly strong water absorption, or when the laundry in the drum is particularly severely knotted, it is very difficult to evenly distribute the laundry in the drum through laundry distribution, resulting in the continuous non-completion of the washing program and affecting the user experience.

[0033] The dehydration control method for a laundry treatment device according to the present invention compares the first eccentricity value with the first preset eccentricity value and the second preset eccentricity value, so that the laundry treatment device directly executes the standard drying mode or the dynamic drying mode or ends the program, and can select a suitable program for operation according to the state of the laundry to be dehydrated, avoiding continuous operation in the case where laundry distribution cannot be performed, so as to end the washing program as soon as possible and improve the user experience; in addition, when the dynamic drying mode is executed, the remaining time on the display screen is replaced with flashing dynamic characters, which can indicate to the user that the dynamic drying mode is being executed, so as to avoid the user suspecting that the device is malfunctioning due to a long remaining time or the remaining time not changing continuously, and improve the user experience.

[0034] Specifically, please refer to Figure 1 , the dehydration control method for a laundry treatment device according to the present invention includes the following steps:

[0035] S1: Detect the eccentricity value of the drum to obtain the first eccentricity value.

[0036] Among them, the eccentricity value is used to characterize the amount by which the drum deviates from the central axis of the drum, and its value can be obtained by detecting the current.

[0037] S2: Compare the first eccentricity value with the first preset eccentricity value.

[0038] S3: Compare the first eccentricity value with the second preset eccentricity value.

[0039] S4: According to the comparison result, the standard spin-drying mode, the dynamic spin-drying mode or the end program is selectively executed.

[0040] Among them, when executing the dynamic spin mode, the remaining time on the display screen is replaced by flashing dynamic characters.

[0041] It should be noted that the standard spin mode of the present invention is the default dehydration mode in the clothing processing device (for example: the dehydration mode after the rinsing in the washing program or the separate dehydration mode in the program), which performs dehydration at the standard spin speed pre-stored in the system for the pre-stored standard spin time. The standard spin speed of the standard spin mode during operation is greater than the dynamic spin speed in the dynamic spin mode. Ending the program means that the clothing processing device ends all running programs, and an alarm is sounded at the same time when the program is ended, so as to remind the user that the clothes to be dehydrated have not been dehydrated, so as to remind the user to hang the clothes out to dry.

[0042] The dehydration control method of the present invention compares the first eccentricity value with the first preset eccentricity value and the second preset eccentricity value, so that the clothing processing device directly executes the standard spin-drying mode or directly executes the dynamic spin-drying mode or ends the program. It can select a suitable program for operation according to the state of the clothes to be dehydrated, avoiding continuous operation when the clothes cannot be distributed, so as to end the washing program as soon as possible and improve the user experience. In addition, when the dynamic spin-drying mode is executed, the remaining time on the display screen is replaced by dynamic characters to flash, which can indicate to the user that the dynamic spin-drying mode is being executed, thereby avoiding the user from suspecting that the equipment is malfunctioning due to the long remaining time on the display screen or the remaining time on the display screen does not change for a long time, thereby improving the user experience.

[0043] It should be noted that the present invention does not impose any limitation on the specific comparison and judgment steps of steps S2-S4. In practical applications, those skilled in the art can set the specific steps of steps S2-S4 according to actual needs.

[0044] In a preferred embodiment, see Figure 2 The second preset eccentricity value is greater than the first preset eccentricity value, and step S2 specifically includes determining whether the first eccentricity value is greater than the first preset eccentricity value. Determining whether the first eccentricity value is greater than the first preset eccentricity value, so as to selectively execute the standard spin-drying mode according to the determination result.

[0045] Among them, the value of the first preset eccentricity is the maximum eccentricity value corresponding to the condition that the drum can be dried at the standard drying speed in the standard drying mode without collision. This first preset eccentricity value is determined by a series of tests before the clothing treatment device leaves the factory, and this value is stored in the controller of the clothing treatment device.

[0046] Step S3 specifically includes determining whether the first eccentricity value is greater than the second preset eccentricity value. Determining whether the first eccentricity value is greater than the second preset eccentricity value is for selectively executing the dynamic drying mode or ending the program according to the determination result.

[0047] Among them, the second preset eccentricity value is the maximum eccentricity value corresponding to the condition that the drum can be dried at a low speed without collision. This second preset eccentricity value is determined by a series of tests before the clothing treatment device leaves the factory, and this value is stored in the controller of the clothing treatment device.

[0048] Step S4 specifically includes:

[0049] S41: Execute the standard drying mode.

[0050] When the first eccentricity value is not greater than the first preset eccentricity value, step S41 is executed to make the clothing treatment device execute the standard drying mode. The standard drying mode is specifically that the drum rotates at the standard drying speed for the drying time.

[0051] S42: Execute the dynamic drying mode.

[0052] When the first eccentricity value is greater than the first preset eccentricity value and not greater than the second preset eccentricity value, step S42 is executed to make the clothing treatment device execute the dynamic drying mode.

[0053] S43: End the program and give an alarm.

[0054] When the first eccentricity value is greater than the second preset eccentricity value, step S43 is executed to end the program and give an alarm.

[0055] It should be noted that although in the above preferred embodiment, step S2 is executed first to determine whether the first eccentricity value is greater than the first preset eccentricity value, and then step S3 is executed to determine whether the first eccentricity value is greater than the second preset eccentricity value, this should not limit the protection scope of the present invention. In practical applications, step S3 can also be executed first and then step S2, or step S2 and step S3 can be executed simultaneously. Adjustments and changes to the specific execution order of steps S2 and S3 do not deviate from the basic principle of the present invention and should all be limited within the protection scope of the present invention.

[0056] Exemplarily, in another embodiment, the second preset eccentricity value is greater than the first preset eccentricity value. Step S2 specifically includes determining whether the first eccentricity value is less than the first preset eccentricity value, so as to selectively execute the standard spin-drying mode according to the determination result.

[0057] Wherein, the value of the first preset eccentricity value is the maximum eccentricity value that can be carried to perform spin-drying at the set spin-drying speed of the standard spin-drying mode without collision. This first preset eccentricity value is a value determined by a series of tests before the clothes treatment device leaves the factory, and this value is stored in the controller of the clothes treatment device.

[0058] Step S3 specifically includes determining whether the first eccentricity value is less than the second preset eccentricity value, so as to selectively execute the dynamic spin-drying mode or end the program according to the determination result.

[0059] Wherein the second preset eccentricity value is the maximum eccentricity value that can be carried to perform spin-drying at a low speed without collision. This second preset eccentricity value is a value determined by a series of tests before the clothes treatment device leaves the factory, and this value is stored in the controller of the clothes treatment device.

[0060] Step S4 specifically includes:

[0061] S41: Execute the standard spin-drying mode.

[0062] When the first eccentricity value is less than the first preset eccentricity value, step S41 is executed to make the clothes treatment device execute the standard spin-drying mode. The standard spin-drying mode specifically means that the drum spins at the standard spin-drying speed for the standard spin-drying time.

[0063] S42: Execute the dynamic spin-drying mode.

[0064] When the first eccentricity value is not less than the first preset eccentricity value and less than the second preset eccentricity value, step S42 is executed to make the clothes treatment device execute the dynamic spin-drying mode.

[0065] S43: End the program and give an alarm.

[0066] When the first eccentricity value is not less than the second preset eccentricity value, step S43 is executed to end the program and give an alarm.

[0067] It should also be noted that the present invention does not impose any restrictions on the specific execution steps of step S42 "execute the dynamic spin-drying mode". In actual applications, those skilled in the art can set the specific execution steps of step S42 according to actual needs.

[0068] Exemplarily, step S42 specifically includes:

[0069] S4201: Determine the dynamic spin speed according to the first eccentricity value.

[0070] Specifically, before leaving the factory, the clothing processing equipment performs a low-speed spin-drying test on the clothes to be dehydrated in different states corresponding to different eccentricity values, and performs tests at different rotational speeds under different eccentricity values, so as to obtain the rotational speeds corresponding to different eccentricity values ​​that can prevent the drum from colliding when rotating, and then obtain a "Comparison Table of Eccentricity Value and Dynamic Spin-drying Speed", and store the "Comparison Table of Eccentricity Value and Dynamic Spin-drying Speed" in the controller, so that the dynamic spin-drying speed corresponding to the first eccentricity value can be directly determined in the "Comparison Table of Eccentricity Value and Dynamic Spin-drying Speed" through the numerical value of the first eccentricity value.

[0071] S4202: Setting the spin time according to the dynamic spin speed.

[0072] Preferably, the setting time is 15s to 30s. More preferably, the setting time is 20s. Setting the setting time to 15s to 30s can not only spin out part of the moisture in the clothes, thereby reducing the eccentricity of the drum, but also minimize the time of low-speed spinning, thereby reducing the time of the dynamic spinning mode, making it easier to use and improving the user experience.

[0073] S4203: Detect the eccentricity value of the drum again to obtain the Nth eccentricity value, where N is the number of times the eccentricity value of the drum is detected.

[0074] After the dynamic spin-drying is set for a certain time, the eccentricity value of the drum is detected again to determine whether it is necessary to switch to the standard spin-drying mode according to the Nth eccentricity value.

[0075] S4204: Determine whether the Nth eccentricity value is greater than the first preset eccentricity value.

[0076] If the Nth eccentricity value is not greater than the first preset eccentricity value, return to step S41 and execute the standard spin mode. If the Nth eccentricity value is greater than the first preset eccentricity value, execute step S4205.

[0077] S4205: Based on the dynamic spin speed during the last spin drying, the dynamic spin speed is increased by one level.

[0078] It should be noted that here the dynamic spin speed is increased by one level, that is, the dynamic spin speed is increased, wherein the increase by one level can be set to increase by 20rpm, increase by 30rpm, or increase by 50rpm, and the specific increased speed value can be determined by technical personnel in this field through experiments.

[0079] In another embodiment, step S4205 may also be replaced by determining a new dynamic spin speed according to the Nth eccentricity value.

[0080] That is, the dynamic spin-drying speed corresponding to the Nth eccentricity value can be determined according to the numerical value of the Nth eccentricity value through the "Comparison Table of Eccentricity Value and Dynamic Spin-drying Speed".

[0081] S4206: Set the spin time according to the new dynamic spin speed; then return to step S4203.

[0082] Preferably, the setting time is 15s to 30s. More preferably, the setting time is 20s. Setting the setting time to 15s to 30s can not only spin out part of the moisture in the clothes, thereby reducing the eccentricity of the drum, but also minimize the time of low-speed spinning, thereby reducing the time of the dynamic spinning mode, making it easier to use and improving the user experience.

[0083] The dehydration control method for a clothes processing device of the present invention is described in detail below through a specific implementation.

[0084] Embodiment

[0085] See also Figure 3 The dehydration control method for a clothes processing device of this embodiment comprises the following steps:

[0086] S1: Detect the eccentricity value of the drum to obtain a first eccentricity value.

[0087] The eccentricity value is used to characterize the amount by which the roller deviates from the central axis of the roller, and its value can be obtained by detecting the current.

[0088] S2: Determine whether the first eccentricity value is greater than a first preset eccentricity value.

[0089] It is determined whether the first eccentricity value is greater than a first preset eccentricity value, so as to selectively execute the standard spin-drying mode according to the determination result. The value of the first preset eccentricity value is the maximum eccentricity value corresponding to the standard spin-drying speed of the standard spin-drying mode and the drum does not collide. The first preset eccentricity value is a value determined by a series of tests before the clothes processing device leaves the factory, and the value is stored in the controller of the clothes processing device.

[0090] S3: Determine whether the first eccentricity value is greater than the second preset eccentricity value, wherein the second preset eccentricity value is greater than the first preset eccentricity value.

[0091] It is determined whether the first eccentricity value is greater than the second preset eccentricity value, so as to selectively execute the dynamic spin-drying mode or end the program according to the determination result. The second preset eccentricity value is the maximum eccentricity value corresponding to the low-speed spin-drying without causing the drum to collide. The second preset eccentricity value is a value determined by a series of tests before the clothes processing device leaves the factory, and the value is stored in the controller of the clothes processing device.

[0092] Exemplarily, the first preset eccentricity value is 300 g, and the second preset eccentricity value is 1000 g.

[0093] S41: Execute the standard spin-drying mode.

[0094] When the first eccentricity value is not greater than the first preset eccentricity value, it indicates that the current first eccentricity value allows the drum to rotate and spin-dry at the standard spin-drying speed, and during the spin-drying process, the drum will not collide and damage the equipment. Execute step S41 to make the laundry processing equipment execute the standard spin-drying mode. Specifically, the standard spin-drying mode is that the drum spins for the standard spin-drying time at the standard spin-drying speed, and this standard spin-drying speed is greater than any level of dynamic spin-drying speed during spin-drying in the dynamic spin-drying mode.

[0095] S42: Execute the dynamic spin-drying mode.

[0096] When the first eccentricity value is greater than the first preset eccentricity value and not greater than the second preset eccentricity value, it indicates that the drum will collide when rotating at the standard spin-drying speed and cannot directly execute the standard spin-drying mode. However, it can be dewatered at a low speed first to reduce the eccentricity value of the drum, and then execute step S42 to make the laundry processing equipment execute the dynamic spin-drying mode.

[0097] S43: End the program and give an alarm.

[0098] When the first eccentricity value is greater than the second preset eccentricity value, it indicates that the current eccentricity value is too large and the drum cannot rotate normally. Then execute step S43 to end the program and give an alarm. Giving an alarm can remind the user that the laundry has ended the program without being dewatered, so as to remind the user to take out the laundry for drying or to take out the laundry, redistribute it, and then select the dewatering program again.

[0099] It should be noted that although in the description of this embodiment, step S2 is executed first to judge whether the first eccentricity value is greater than the first preset eccentricity value, and then step S3 is executed to judge whether the first eccentricity value is greater than the second preset eccentricity value, this should not constitute a limitation to the protection scope of the present invention. In practical applications, step S3 can also be executed first and then step S2, or step S2 and step S3 can be executed simultaneously. Adjustments and changes to the specific execution order of steps S2 and S3 do not deviate from the basic principle of the present invention and should all be limited within the protection scope of the present invention.

[0100] Specifically, please continue to refer to Figure 3 , step S42 of this embodiment specifically includes:

[0101] S421: Determine the dynamic spin-drying speed according to the first eccentricity value.

[0102] Specifically, before leaving the factory, the clothing processing equipment performs a low-speed spin-drying test on the clothes to be dehydrated in different states corresponding to different eccentricity values, and performs tests at different rotational speeds under different eccentricity values, so as to obtain the maximum rotational speed corresponding to different eccentricity values ​​that can prevent the drum from colliding when rotating, and then obtain a "Comparison Table of Eccentricity Value and Dynamic Spin-drying Speed", and store the "Comparison Table of Eccentricity Value and Dynamic Spin-drying Speed" in the controller, so that the dynamic spin-drying speed corresponding to the first eccentricity value can be directly determined in the "Comparison Table of Eccentricity Value and Dynamic Spin-drying Speed" through the numerical value of the first eccentricity value.

[0103] Exemplarily, when the eccentricity value is greater than 300g and less than or equal to 500g, the dynamic spin speed is 300rpm; when the eccentricity value is greater than 500g and less than or equal to 650g, the dynamic spin speed is 270rpm; when the eccentricity value is greater than 650g and less than or equal to 750g, the dynamic spin speed is 240rpm; when the eccentricity value is greater than 750g and less than or equal to 850g, the dynamic spin speed is 210rpm; when the eccentricity value is greater than 850g and less than or equal to 900g, the dynamic spin speed is 180rpm; when the eccentricity value is greater than 900g and less than or equal to 950g, the dynamic spin speed is 160rpm; when the eccentricity value is greater than 950g and less than or equal to 1000g, the dynamic spin speed is 130rpm.

[0104] S422: Setting the spin-drying time according to the dynamic spin-drying speed.

[0105] Preferably, the setting time is 15s to 30s. More preferably, the setting time is 20s. Setting the setting time to 15s to 30s can not only spin out part of the moisture in the clothes, thereby reducing the eccentricity of the drum, but also minimize the time of low-speed spinning, thereby reducing the time of the dynamic spinning mode, making it easier to use and improving the user experience.

[0106] S423: Detect the eccentricity value of the drum again to obtain the Nth eccentricity value, where N is the number of times the eccentricity value of the drum is detected.

[0107] After the dynamic spin-drying is set for a certain time, the eccentricity value of the drum is detected again so as to determine whether it is necessary to switch to the standard spin-drying mode or to end the program according to the Nth eccentricity value.

[0108] S424: Determine whether the Nth eccentricity value is smaller than the first eccentricity value.

[0109] First, the Nth eccentricity value is compared with the first eccentricity value to determine whether the Nth eccentricity value is smaller than the first eccentricity value, thereby determining whether the eccentricity value has been reduced in the previous spin-drying operation, so as to determine whether the program needs to be terminated.

[0110] If the Nth eccentricity value is less than the first eccentricity value, it means that the previous low-speed spin-drying operation is valid, then continue to execute step S425; if the Nth eccentricity value is not less than the first eccentricity value, it means that the previous low-speed spin-drying operation is invalid, execute step S43, end the program, and issue an alarm.

[0111] S425: Determine whether the Nth eccentricity value is greater than the first preset eccentricity value.

[0112] Then the Nth eccentricity value is compared with the first preset eccentricity value to determine whether the Nth eccentricity value is greater than the first preset eccentricity value, thereby determining whether to switch to the standard spin-drying mode.

[0113] If the Nth eccentricity value is greater than the first preset eccentricity value, continue to execute step S426; if the Nth eccentricity value is not greater than the first preset eccentricity value, execute step S41, that is, switch to the standard spin-drying mode.

[0114] S426: Based on the dynamic spin speed during the last spin drying, the dynamic spin speed is increased by one level.

[0115] Since partial dehydration has been performed in the last spin, the eccentricity value has been reduced. Therefore, based on the dynamic spin speed in the last spin, the dynamic spin speed is increased by one level, and the eccentricity value of the drum is further reduced by gradually increasing the speed.

[0116] For example, increasing the speed by one level may be set to increase the dynamic spin speed by 20 rpm on the original basis.

[0117] For example, increasing the speed by one level may be set to increase the dynamic spin speed by 30 rpm on the original basis.

[0118] For example, increasing the speed by one level may be set to increase the dynamic spin speed by 50 rpm on the original basis.

[0119] In another embodiment, step S426 may also be replaced by determining a new dynamic spin speed according to the Nth eccentricity value.

[0120] That is, the dynamic spin-drying speed corresponding to the Nth eccentricity value can be determined according to the numerical value of the Nth eccentricity value through the "Comparison Table of Eccentricity Value and Dynamic Spin-drying Speed".

[0121] Although two specific implementation methods of step S426 are given above, in actual application, it is still preferred to increase the dynamic spin speed by one level based on the dynamic spin speed during the last spin drying. By increasing the dynamic spin speed in a step-by-step manner, the operation is more stable, the judgment process is simpler, and the control operation is more convenient.

[0122] S427: Perform dehydration for the set time according to the new dynamic dehydration speed, and then return to step S423.

[0123] After dehydration again, return to execute step S423, detect the new eccentricity value again, and then make a judgment and comparison according to the new Nth eccentricity value.

[0124] Preferably, the set time is 15s to 30s. Further preferably, the set time is 20s. Setting the set time to 15s to 30s can not only dehydrate part of the moisture of the clothes, thereby reducing the eccentricity value of the drum, but also minimize the time of low-speed dehydration, thereby reducing the time of the dynamic dehydration mode, which is convenient to use and improves the user experience.

[0125] In addition, the present invention also provides a laundry treatment device, which includes a controller configured to be able to execute the above-mentioned dehydration control method for a laundry treatment device.

[0126] The laundry treatment device of the present invention can be a drum washing machine, a pulsator washing machine, a washing and drying integrated machine or the like.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
