Description

[0001] The present application relates to the field of clothes treatment, in particular to a spin-drying control method, a controller and a load treatment device. BACKGROUND

[0002] When a load such as clothes or shoes is subjected to spin-drying treatment, the load treatment device with spin-drying function needs to increase the spin-drying speed to a certain value to ensure the spin-drying effect. Taking a washing machine as an example, the current washing machine detects the eccentricity value of the load before spin-drying the load. Only when the detected eccentricity value reaches the set eccentricity value, the spin-drying can be performed. For the case of small amount of clothes, the smaller the amount of clothes, the larger the eccentricity value, which causes the spin-drying speed to be too small due to the too large eccentricity value of the load, resulting in unsatisfactory spin-drying effect. SUMMARY

[0018] The spin-drying program further comprises:

[0019] Before the load to be spun-dried is spun-dried, eccentricity detection is performed on the load to be spun-dried to obtain an actual eccentricity value.

[0020] When the actual eccentricity value matches a preset target eccentricity value, the load to be spun-dried is spun-dried.

[0021] The eccentricity detection is performed by periodically increasing and decreasing the rotation speed of the processing drum.

[0022] Optionally, the spin-drying program further comprises:

[0023] Before the load to be spun-dried is spun-dried, the processing drum is controlled to perform a leveling process on the load to be spun-dried, and the maximum rotation speed of the processing drum during the leveling process is adjusted to a preset target value to level the load to be spun-dried.

Because different dehydration programs have different running times and / or dehydration times, when the actual maximum dehydration rotation speed is in the rotation speed interval with smaller rotation speed, the processing mode with more running times and / or longer dehydration time can be selected to improve the dehydration effect.

[0046] In order to enable personnel in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should fall within the scope of protection of the present application.

[0047] It is to be understood that the terms "first", "second", and the like, used in the description and the claims of the present application as well as the above description of the drawings merely refer to different categories and do not imply a specific order or chronology of events. It is to be understood that the use of the term "about" with respect to a given numerical value or a range of values refers to a range of values that fall within 20% of that value or range of values. It is to be understood that the use of the term "at least one of' with respect to a given list of items refers to a list of one or more items, but does not exclude additional items not expressly listed. It is to be understood that the use of the term "includes" or "including", or "has" or "having", or variants thereof, in the detailed description or the claims of the present application is intended to cover the respective items listed thereafter without precluding additional items not expressly recited. It is to be understood that the use of the term "or" in the detailed description or the claims of the present application has the same meaning as "and / or" unless the context clearly indicates otherwise.

[0048] According to an embodiment of the present application, an embodiment of a dewatering control method is provided. It is to be understood that the steps illustrated in the flowcharts of the drawings can be performed in a computer system such as a set of computer-executable instructions, and although a logical sequence of steps is illustrated in the flowcharts, in some cases, the steps shown or described can be performed in an order other than that depicted.

[0049] When a load such as laundry or shoes is subjected to dewatering treatment, the load treatment apparatus is prone to have a dewatering rotation speed that is too small due to an excessive eccentricity value of the load, resulting in an unsatisfactory dewatering effect. Taking a drum-type fully-automatic washing machine (hereinafter referred to as a drum washing machine) as an example, the dewatering mode of the drum washing machine is to detect the eccentricity value of the load, and then control the final rotation speed of dewatering according to the eccentricity value. When the eccentricity value of the load is large, the rotation speed of the treatment drum of the drum washing machine is affected and reduced, and the moisture content of the load after dewatering is increased. Conversely, when the eccentricity value of the load is small, the rotation speed of the treatment drum of the drum washing machine is easily increased, and the moisture content of the load after dewatering is reduced.

[0050] However, the existing drum washing machine has the following shortcomings: when a small amount of laundry is washed, the eccentricity value of the load is too large, which does not meet the set eccentricity value, resulting in that the dewatering cannot reach the set rotation speed, and finally causing the load to be incompletely dewatered and the moisture content to not meet the requirements. The current solution is to enlarge the set eccentricity value, so that the excessive eccentricity value of the load can also meet the set eccentricity value, so that the rotation speed of the treatment drum of the drum washing machine is increased to dewater the load. This solution will further cause another problem, i.e., when the rotation speed of the treatment drum is increased due to the excessive eccentricity value of the load, the drum is hit and the drum washing machine is displaced, which can easily damage the washing machine and cause a poor user experience. At the same time, the excessive eccentricity value of the load also causes the actual maximum rotation speed during the dewatering process of the treatment drum to fail to reach the set target rotation speed, and the moisture content of the load after dewatering is still high, which reduces the dewatering effect.

[0051] Based on this, the dewatering control method provided in the embodiments of the present application is based on the following inventive concept:

[0052] For the case of a small amount of load, the swing leveling speed of the processing drum is first changed, so that the speed of the processing drum is more likely to stretch the load during the load leveling process of the processing drum, thereby reducing the eccentricity value of the load. At the same time, without reducing the set eccentricity value, a dewatering program with different running times and / or dewatering durations is selected according to the actual maximum dewatering speed of the processing drum during the dewatering process of the load, thereby improving the dewatering effect of the load and reducing the moisture content of the load after dewatering.

[0053] The dewatering control method provided in the embodiments of the present application can be applied to an application environment as shown in the figure, which includes a smart device 10, a gateway 20, a router 30, a server 40, and a user terminal 50. Figure 1

[0054] Specifically, the user terminal 50, which can also be considered as a user end or a terminal, can be used to deploy (or install) the client associated with the smart device 10. The user terminal 50 can be a smartphone, a notebook computer, a personal computer, a tablet computer, a smart control panel, or other electronic devices that can implement network connection, and is not limited herein.

[0055] The user terminal 50 is associated with the smart device 10. In essence, the user registers an account in the user terminal 50 and configures the smart device 10 in the user terminal 50. For example, the configuration includes adding a device identifier to the smart device 10, so that when the user terminal 50 is running, it can provide the user with device display and device control functions related to the smart device 10. The user terminal 50 can be in the form of an application program or a web page. Accordingly, the interface for device display of the user terminal 50 can be in the form of a program window or a web page, and is not limited herein.

[0056] ​The smart device 10 is deployed in the gateway 20 and communicates with the gateway 20 through a communication module configured by itself, and is controlled by the gateway 20. It should be understood that the smart device 10 generally refers to one of a plurality of smart devices 10, and the embodiments of the present application are only exemplified by the smart device 10, that is, the number and type of the smart device 10 deployed in the gateway 20 are not limited in the embodiments of the present application. In one application scenario, the smart device 10 accesses the gateway 20 through a local area network, so as to be deployed in the gateway 20. The process of the smart device 10 accessing the gateway 20 through the local area network includes: first establishing a local area network by the gateway 20, and the smart device 10 connects the gateway 20 to join the local area network established by the gateway 20. The local area network includes but is not limited to ZIGBEE or Bluetooth. The smart device 10 can be a controller, MCU, chip, PLC control board, single-chip microcomputer or electronic equipment such as a washing machine, a washer-dryer and a washer-dryer-integrated machine with control function and communication function.

[0057] The interaction between the user terminal 50 and the smart device 10 can be realized through a local area network, and can also be realized through a wide area network. In one application scenario, the user terminal 50 establishes a wired or wireless communication connection between the router 30 and the gateway 20, for example, the wired or wireless communication connection includes but is not limited to WIFI and the like, so that the user terminal 50 and the gateway 20 are deployed in the same local area network, and then the user terminal 50 can realize the interaction with the smart device 10 through a local area network path. In another application scenario, the user terminal 50 establishes a wired or wireless communication connection between the server 40 and the gateway 20, for example, the wired or wireless communication connection includes but is not limited to 2G, 3G, 4G, 5G, WIFI and the like, so that the user terminal 50 and the gateway 20 are deployed in the same wide area network, and then the user terminal 50 can realize the interaction with the smart device 10 through a wide area network path.

[0058] The server 40 can also be considered as a cloud, a cloud platform, a platform end, a server end and the like. The server 40 can be a server 40, a server 40 cluster composed of a plurality of servers 40, or a cloud computing center composed of a plurality of servers 40, so as to better provide background services to a large number of user terminals 50. For example, the background services include smart device 10 control services.

[0059] In one application scenario, the server 40 controls the smart device 10 to run the dehydration program to dehydrate the load to be dehydrated and obtain the actual maximum dehydration rotating speed of the processing drum of the smart device 10 before the dehydration ends after the smart device 10 uploads the determination signal. The server 40 controls the smart device 10 to execute the remaining stage of the dehydration program according to the actual maximum dehydration rotating speed, and the number of running and / or the dehydration time in the remaining stage corresponding to different actual maximum dehydration rotating speeds are different.

[0060] In another application scenario, the smart device 10 includes a first device and a second device, wherein the first device refers to a device for dehydrating the load, and the second device refers to a device for controlling the first device. The second device controls the first device to run the dehydration program to dehydrate the load to be dehydrated and obtain the actual maximum dehydration rotating speed of the processing drum of the first device before the dehydration ends after the first device uploads the determination signal. The second device controls the first device to execute the remaining stage of the dehydration program according to the actual maximum dehydration rotating speed, and the number of running and / or the dehydration time in the remaining stage corresponding to different actual maximum dehydration rotating speeds are different. The first device and the second device can be separately arranged or the second device can be integrated into the first device, and the present embodiment is not limited in this regard. For the separately arranged first device and the second device, the first device and the second device both have communication functions and communicate through the gateway 20.

[0061] In other application scenarios, the user can configure the parameters in the smart device 10 by using the user terminal 50. For example, when the smart device 10 is a washing machine, the user can set the dehydration time and the start-up time of the washing machine. The smart device 10 can upload its running data to the server 40 through the gateway 10 and the router 30, so that the server 40 records the running data to facilitate the monitoring of the smart device 10 by the server 40. The communication content between the smart device 10, the server 40 and the user terminal 50 is not limited in the present embodiment.

[0062] Based on this, the present application provides a dehydration control method, as shown in Figure 2 The electronic device can be the server 40 in the application environment as shown in Figure 1 or the smart device 10 in the application environment as shown in Figure 1 .

[0063] In the following method embodiments, the execution subject of each step of the method is taken as an example of the electronic device for ease of description, but this is not a specific limitation.

[0064] The method is applied to a load processing device with a dehydration function, and the load processing device includes a processing drum, as shown in Figure 2As shown, the method can comprise the following steps,

[0065] S101, in response to a determination signal that the to-be-dehydrated load belongs to a target load condition, running a dehydration program to dehydrate the to-be-dehydrated load.

[0066] S102, obtaining the actual maximum dehydration rotation speed of the processing drum before the dehydration of the to-be-dehydrated load ends.

[0067] Different to-be-dehydrated loads have different load conditions, where the load condition refers to the condition of the number of loads or the condition of the weight of the load. Taking the condition of the weight of the load as an example, the target load condition in this embodiment refers to the condition of the smaller weight of the load. That is, the target load condition referred to in this embodiment refers to the condition that the number of loads is small or the weight of the load is small, so that the eccentricity value of the to-be-dehydrated load is prone to be too large. In some specific application scenarios, a threshold can be set to determine whether the to-be-dehydrated load belongs to the target load condition, for example, when the number of loads is less than 3 or less than 2, it is considered to belong to the target load condition; when the weight of the load is less than 1 kg, 3 kg, or less than 10% of the maximum load processing capacity of the load processing device, it is considered to belong to the target load condition. In addition, whether the to-be-dehydrated load belongs to the target load condition can also be determined according to the material type of the to-be-dehydrated load, the type of clothes, and in combination with the number of loads. For example, if the material type of the to-be-dehydrated load is fiber and the number of loads is less than 5, it is considered to belong to the target load condition; if the type of clothes of the to-be-dehydrated load is a shirt and the number of loads is less than 5, it is considered to belong to the target load condition. This embodiment does not make specific limitations.

[0068] When the to-be-dehydrated load belongs to the target load condition, a determination signal is triggered. The determination signal can be generated by the electronic device itself to respond accordingly, or it can be transmitted to the electronic device by other devices to make the electronic device respond accordingly. For example, in an application scenario, the electronic device is the server 40 in Figure 1 The load number detection sensor (such as a radar sensor) in the load processing device detects the number of loads, determines that the to-be-dehydrated load belongs to the target load condition, generates a determination signal, and uploads the determination signal to the server 40, so that the server 40 responds to the determination signal. In another application scenario, the electronic device is a controller integrated in the load processing device, and the user triggers the determination signal through voice, action, or button to make the electronic device respond to the determination signal. The trigger subject of the determination signal is not limited in this embodiment.

[0069] When the to-be-dehydrated load belongs to the target load case, it is proved that the eccentricity value of the to-be-dehydrated load is prone to be too large, so the actual maximum dehydrating speed of the processing cylinder is obtained before the dehydration of the to-be-dehydrated load is completed. The dehydration effect of the to-be-dehydrated load can be known through the actual maximum dehydrating speed, for example, the smaller the actual maximum dehydrating speed, the worse the dehydration effect. Thus, how to improve the dehydration effect and reduce the water content of the to-be-dehydrated load after dehydration can be determined according to the actual maximum dehydrating speed.

[0070] The actual maximum dehydrating speed can be obtained in various ways according to actual conditions. For example, it can be obtained by user input. For another example, the maximum speed of the processing cylinder reached when the to-be-dehydrated load is dehydrated can be detected, and the maximum speed is taken as the actual maximum dehydrating speed. It should be noted that the time node for obtaining the actual maximum dehydrating speed should be before the dehydration is completed. Specifically, during the dehydration of the to-be-dehydrated load, the speed of the processing cylinder is usually controlled to rise, and when the speed of the processing cylinder rises to a target value or fluctuates around a certain value, the target value or the certain value can be determined as the actual maximum dehydrating speed. The actual maximum dehydrating speed can also be detected in a pre-dehydration stage by setting a pre-dehydration mode.

[0071] S103, executing the remaining stage of the dehydration program according to the speed interval in which the actual maximum dehydrating speed is located.

[0072] The remaining stage refers to the stage after the actual maximum dehydrating speed is obtained in the dehydration program.

[0073] Different speed intervals correspond to different running times of the dehydration program in the remaining stage and / or different dehydration durations in the remaining stage. That is, different speed intervals determine different running times and / or different dehydration durations. That is, the running times of the dehydration program in the remaining stage are determined according to different speed intervals, that is, the running times are determined after the actual maximum dehydrating speed is obtained.

[0074] It should be noted that multiple speed intervals are preset, and the speeds of the processing cylinder corresponding to different speed intervals are different. In an application scenario, multiple speed intervals can be divided by setting multiple thresholds. For example, the thresholds set include 600 and 800, so that the speed intervals include less than 600 rpm, 600-800 rpm and greater than 800 rpm. Different speed intervals correspond to different dehydration programs.

[0075] Through the above, if the to-be-dehydrated load belongs to the target load case, since the eccentricity value of the to-be-dehydrated load is prone to be too large in this case, even if the to-be-dehydrated load is dehydrated, it is difficult to ensure that the actual maximum dehydration rotation speed reaches the expected value, that is, the actual maximum dehydration rotation speed cannot guarantee the dehydration effect of the to-be-dehydrated load, and the to-be-dehydrated load is prone to have a high water content rate after dehydration treatment. Based on this, the technical scheme of the present application does not adjust the preset eccentricity value, but directly dehydrates the to-be-dehydrated load, obtains the actual maximum dehydration rotation speed in the dehydration process, and executes the corresponding dehydration program according to the rotation speed interval in which the actual maximum dehydration rotation speed is located. Since different dehydration programs have different running times and / or dehydration times, when the actual maximum dehydration rotation speed is in a rotation speed interval with a smaller rotation speed, a processing mode with more running times and / or longer dehydration time can be selected, thereby improving the dehydration effect.

[0076] In another embodiment of the present application, the rotation speed interval includes a first interval, a second interval and a third interval, the rotation speed represented by the first interval is greater than the rotation speed represented by the second interval, and the rotation speed represented by the second interval is greater than the rotation speed represented by the third interval.

[0077] As shown in Figure 3 The remaining stage of executing the dehydration program according to the rotation speed interval in which the actual maximum dehydration rotation speed is located includes:

[0078] S201, if the actual maximum dehydration rotation speed is in the first interval, the running times in the remaining stage are the same as the preset reference running times, and the dehydration time is the same as the preset reference dehydration time;

[0079] S202, if the actual maximum dehydration rotation speed is in the second interval, the running times in the remaining stage are the same as the reference running times, and the dehydration time is greater than the reference dehydration time;

[0080] S203, if the actual maximum dehydration rotation speed is in the third interval, the running times in the remaining stage are greater than the reference running times, and the dehydration time is the same as the reference dehydration time.

[0081] That is, the reference dehydration parameters are set in advance, and the reference running times and the reference dehydration time are included in the reference dehydration program. When the actual maximum dehydration rotation speed is in the first interval, because the processing cylinder rotation speed represented by the first interval is large, at this time, the running times are the same as the reference running times in the reference dehydration program, and the dehydration time is the same as the reference dehydration time in the reference dehydration program. That is, the remaining stage can directly execute the reference dehydration parameters.

[0082] For the case that the actual maximum dewatering speed is in the second interval and the third interval, the running number and / or the dewatering time are adjusted respectively, so that the dewatering time of the load to be dewatered is longer or the dewatering rounds are more, to compensate for the poor dewatering effect caused by the slow speed of the processing cylinder during dewatering.

[0083] According to the above, for the case that the actual maximum dewatering speed is in the second interval, the dewatering time in the remaining stages is longer than the reference dewatering time, so that the load to be dewatered is in the dewatering state for a longer time, the water content of the load to be dewatered is reduced, and the dewatering effect is improved. For the case that the actual maximum dewatering speed is in the third interval, the processing cylinder speed is small under this condition, which is difficult to meet the dewatering demand, so the running number of the remaining stages is larger, so that the load processing equipment runs the dewatering program multiple times, and the eccentricity of the load to be dewatered may be different in different rounds of the dewatering program, and the actual maximum dewatering speed of the processing cylinder may be different, which helps to improve the eccentricity of the load to be dewatered, increase the speed of the processing cylinder during dewatering, and ensure the dewatering effect of the load to be dewatered.

[0084] In another embodiment of the present application, the method further comprises:

[0085] When the dewatering time is longer than the reference dewatering time, it is at least twice the reference dewatering time;

[0086] When the running number is greater than the reference running number, it is at least one more than the reference running number.

[0087] For example, the reference dewatering time is t1, and the extended dewatering time is 2*t1. The reference running number is n, and the increased running number is n+k, where k is a positive integer.

[0088] According to the above, the extended dewatering time is twice the reference dewatering time, so that the load to be dewatered can be in the dewatering state for a longer time, which helps to improve the dewatering effect of the load to be dewatered. Similarly, the increased running number is at least one more than the reference running number, so that the load processing equipment at least performs the dewatering program on the load to be dewatered once, which helps to improve the dewatering effect of the load to be dewatered.

[0089] In another embodiment of the present application, the running number refers to the total number of dewatering program runs, and the dewatering time refers to the total dewatering time of the load to be dewatered after the speed of the processing cylinder reaches the actual maximum dewatering speed during the dewatering program run.

[0090] It should be noted that the dehydration program can include the flattening treatment, the eccentricity detection and the dehydration treatment of the load to be dehydrated. If only the dehydration time is prolonged, it is proved that only the total time of the dehydration treatment is prolonged, and if the running times are increased, it is proved that the load treatment device will run the dehydration program multiple times, and each time the load to be dehydrated will be flattened, detected for eccentricity and dehydrated, so that the flattening and eccentricity of the load to be dehydrated are easily improved, so that the rotation speed of the treatment drum during the dehydration treatment can be higher, so as to improve the dehydration effect.

[0091] As shown in Figure 4 the dehydration program further includes:

[0092] S301, before dehydrating the load to be dehydrated, detecting the eccentricity of the load to be dehydrated to obtain an actual eccentricity value.

[0093] Specifically, the eccentricity detection can be realized by using a sensor, or by detecting the current value of the motor for driving the treatment drum to rotate, and then calculating the actual eccentricity value. The eccentricity detection can also be calculated by a software algorithm according to the rotation speed and torque of the motor for driving the treatment drum to rotate. The present embodiment does not make specific limitation on this.

[0094] S302, when the actual eccentricity value matches the preset target eccentricity value, dehydrating the load to be dehydrated.

[0095] The target eccentricity value refers to the eccentricity value that can dehydrate the load to be dehydrated. It should be noted that the target eccentricity value in the present embodiment is also applicable to the case where the number of loads is large. For example, when the load weight of the load to be dehydrated is less than 1 kg, it belongs to the target load condition, and at this time the target eccentricity value is 100, but for the load to be dehydrated with a load weight between 1-3 kg, the target eccentricity value is also 100. That is, the dehydration control method in the present embodiment does not use a larger target eccentricity value because of smaller load weight or smaller number of loads. It is helpful to avoid the situation of hitting the cylinder or displacement of the load treatment device during the dehydration process, and to ensure the user experience.

[0096] It should be noted that when the load weight difference is large, the target eccentricity value will also change accordingly. Specifically, the corresponding target eccentricity value can be determined according to the function book of the load handling device, and different load amounts and different set speeds are determined in the main control program. That is, different load amounts, due to different weights in the processing cylinder, the balance of the processing cylinder when rotating is different, and the eccentricity is also different. Therefore, different load weights need to correspond to different target eccentricity values. For example, for a load of 8-10 kg, the target eccentricity value can be i, for a load of 5-8 kg, the target eccentricity value can be o, for a load of 3-5 kg, the target eccentricity value can be p, and for a load of 0-3 kg, the target eccentricity value can be q. This embodiment only does not distinguish 0-1 kg separately, and still uses the same gear target eccentricity value.

[0097] When the actual eccentricity value matches the target eccentricity value, it proves that the actual eccentricity value is less than the target eccentricity value, at this time the actual eccentricity value of the load to be dewatered is in line with the dewatering requirement, that is, the corresponding dewatering program can be executed to dewater the load to be dewatered.

[0098] Wherein, when the eccentricity detection is performed, the speed of the processing cylinder is periodically increased and decreased.

[0099] Specifically, during the dewatering process, the speed of the processing cylinder is gradually increased in steps to the highest actual speed that can be reached, and then slowly decreases to 0 after a small period of time is set. The so-called step-up, such as 93, then 120, then 150, then 200, 400, etc. until the highest actual speed that can be reached.

[0100] That is, when the remaining phase is executed, it is first judged whether the total time length of the load to be dewatered for dewatering reaches the dewatering time length, and if it does, it is judged whether the total number of times of execution of the dewatering program for the load to be dewatered reaches the running number. If not, the dewatering program is re-executed to re-dewater the load to be dewatered.

[0101] Through the above content, since the dewatering program includes eccentricity detection, when the corresponding dewatering program is re-executed, the eccentricity detection of the load to be dewatered will be re-performed, which helps to update the actual eccentricity value of the load to be dewatered, so that the speed of the processing cylinder during the dewatering process of the load to be dewatered is higher, and the dewatering effect is improved.

[0102] In another embodiment of the present application, the dewatering program further comprises:

[0103] Before dewatering the load to be dewatered, the processing cylinder is controlled to perform a leveling process on the load to be dewatered, and the maximum speed of the processing cylinder during the leveling process is adjusted to a preset target value to level the load to be dewatered.

[0104] Specifically, the flattening treatment refers to a treatment for reducing the eccentricity value of the load to be dewatered. For example, the flattening treatment is to control the treatment drum to periodically rotate forward and reverse, and during the forward and reverse rotation, the rotation speed of the treatment drum is increased from low to high and then decreased from high to low, so that the load to be dewatered is easily flattened in the treatment drum, and the flattening of the load to be dewatered is achieved.

[0105] Through the above, the flattening treatment is performed on the load to be dewatered before dewatering, which helps to reduce the actual eccentricity value of the load to be dewatered, so that the load to be dewatered is dewatered faster, and the dewatering efficiency is improved. At the same time, the smaller actual eccentricity value helps to increase the actual maximum dewatering speed and improve the dewatering effect.

[0106] In another embodiment of the present application, the method further comprises:

[0107] During the flattening treatment, the eccentricity of the load to be dewatered is detected.

[0108] That is, the dewatering program further comprises the flattening treatment.

[0109] Through the above, since the eccentricity detection and the flattening treatment are performed simultaneously, the dewatering program includes the flattening treatment phase, so that when the dewatering program is re-executed, the flattening treatment is also re-executed, which helps to further reduce the actual eccentricity value of the load to be dewatered. The smaller actual eccentricity value helps to increase the actual maximum dewatering speed and improve the dewatering effect.

[0110] In another embodiment of the present application, the method further comprises:

[0111] According to the matching relationship between the load weight of the load to be dewatered and the preset weight threshold, it is determined whether the load to be dewatered belongs to the target load condition. When the load weight is less than the weight threshold, it is determined that the load to be dewatered belongs to the target load condition.

[0112] Through the above, the load weight is used to determine whether the load to be dewatered belongs to the target load condition. The load weight is easy to obtain and easy to ensure accuracy, which helps to improve the accuracy of determining whether the load to be dewatered belongs to the target load condition.

[0113] In another embodiment of the present application, as shown in Figure 5 the method further comprises:

[0114] S401, obtaining the running mode of the load treatment equipment;

[0115] S402, obtaining the load weight of the load to be dewatered and the weight threshold according to the running mode;

[0116] Different operation modes correspond to different load weight acquisition methods and different weight thresholds.

[0117] The load processing device includes multiple operation modes, and different operation modes correspond to different load weight acquisition methods and different weight thresholds.

[0118] According to the above, the load weight acquisition method and the weight threshold are adjusted according to the different operation modes, which helps the load weight acquisition method and the weight threshold to be more suitable for the load to be dehydrated under the corresponding operation mode, thereby improving the efficiency and accuracy of the load weight acquisition and the accuracy of determining whether the load to be dehydrated belongs to the target load.

[0119] In another embodiment of the present application, the load weight and the weight threshold of the load to be dehydrated are obtained according to the operation mode, comprising:

[0120] If the operation mode is a single dehydration mode, the weight of the load to be dehydrated is detected to obtain a first load weight, and the weight threshold is determined as a first weight threshold corresponding to the single dehydration mode;

[0121] If the operation mode is a multi-processing mode including washing and dehydration, a second load weight obtained by detecting the weight of the load to be dehydrated before washing is obtained, and the weight threshold is determined as a second weight threshold corresponding to the multi-processing mode;

[0122] The load weight includes the first load weight and the second load weight, and the weight threshold includes the first weight threshold and the second weight threshold, and the first weight threshold is greater than the second weight threshold.

[0123] The multi-processing mode can directly obtain the second load weight weighed before washing, reducing the weight detection process.

[0124] It should be noted that if it is a single dehydration mode, the load to be dehydrated during weight detection is in a water-containing state, and if it is a multi-processing mode, the second load weight obtained is the weight of the load to be dehydrated when it is dry. Therefore, different water content conditions of the load to be dehydrated will correspond to different weight thresholds.

[0125] Through the above, for the single dehydration mode, since the weight detection is performed on the dehydration load immediately, and the dehydration load is easy to be in a wet state, that is, contains moisture, a larger first weight threshold is used, so that the use of the weight threshold is consistent with the actual situation of the dehydration load, which helps to improve the accuracy of determining whether the dehydration load belongs to the target load condition. For the multi-processing mode, the second load weight obtained by the weight detection on the dehydration load before washing is directly obtained, which saves the weight detection process and helps to improve the dehydration efficiency, and at the same time, a smaller second weight threshold is used, so that the use of the weight threshold is consistent with the actual situation of the dehydration load, which helps to improve the accuracy of determining whether the dehydration load belongs to the target load condition.

[0126] For the convenience of understanding, the dehydration control method of the present application is described taking the load processing equipment as a drum washing machine. The drum washing machine includes a washing function and a dehydration function, and the load is weighed when the washing function is executed to obtain the load weight in a dry state. Correspondingly, the drum washing machine includes a single dehydration mode and a multi-processing mode.

[0127] As shown in Figure 6 , in response to the dehydration program running signal, it is judged whether the running mode of the load processing equipment is the single dehydration mode;

[0128] If the running mode is the single dehydration mode, the weight detection is performed on the dehydration load to obtain the first load weight;

[0129] If the running mode is not the single dehydration mode, the second load weight obtained by the weight detection on the dehydration load before washing is obtained;

[0130] It is judged whether the first load weight is less than a preset first weight threshold or whether the second load weight is less than a preset second weight threshold;

[0131] If the first load weight is less than the first weight threshold or the second load weight is less than the second weight threshold, it proves to be the target load condition, that is, the extremely small load condition. The leveling processing of the processing cylinder on the dehydration load is controlled, and the maximum speed of the processing cylinder in the leveling processing process is adjusted to a preset target value R1, wherein 50rpm≤R1≤60rpm, so as to realize the good unfolding of the clothes and facilitate the reduction of the eccentricity value;

[0132] The eccentricity detection is performed in the leveling processing process to obtain an actual eccentricity value;

[0133] It is judged whether the actual eccentricity value is less than a preset target eccentricity value;

[0134] If the actual eccentricity value is not less than the target eccentricity value, the leveling processing of the dehydration load is maintained and the eccentricity detection is performed;

[0135] If the actual eccentricity value is less than the target eccentricity value, the control process increases the rotation speed of the processing drum to dewater the load to be dewatered;

[0136] The actual maximum dewatering rotation speed of the processing drum during the dewatering process is obtained;

[0137] If the actual maximum dewatering rotation speed is greater than or equal to the first rotation speed threshold (800 rpm), the dewatering of the load to be dewatered is completed according to the reference dewatering parameters preset in the dewatering program, wherein the reference dewatering parameters include a reference number of operations and a reference dewatering duration; and the reference number of operations is 1.

[0138] If the actual maximum dewatering rotation speed is less than the first rotation speed threshold (800 rpm) and greater than or equal to the second rotation speed threshold (600 rpm), the reference dewatering duration is extended, and the dewatering is ended when the actual dewatering duration reaches the extended reference dewatering duration.

[0139] If the actual maximum dewatering rotation speed is less than the second rotation speed threshold (600 rpm), the load to be dewatered is dewatered according to the reference dewatering parameters, and the number of operations of the dewatering program is accumulated to 0 after the dewatering is completed. It is determined whether the number of operations of the dewatering program is 1, if not, the actual eccentricity value of the load to be dewatered is re-obtained, and the subsequent process of eccentricity detection is performed again according to the re-obtained actual eccentricity value, if yes, the dewatering is ended.
