[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0052] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0053] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0054] To address the problem of inaccurate runtime display in existing laundry handling equipment, this embodiment discloses a method for correcting laundry time in its first aspect, such as... Figure 1 As shown, the method includes S1 to S2, wherein:

[0055] S1, after the user selects the washing machine's operating mode and before the washing machine executes the washing program, detects factors that affect washing time;

[0056] S2, based on the values ​​of factors affecting washing time and the corresponding correction strategies, corrects the preset running time in the operation mode.

[0057] The washing time of garment handling equipment is affected by multiple factors, including water intake time, washing temperature, defoaming time, and garment eccentricity adjustment. The actual program runtime often differs significantly from the default runtime. To address this issue, the method provided in this embodiment detects factors affecting runtime before the washing machine starts operating the selected mode after the clothes are loaded. Based on the detected factors, the preset runtime of the selected operating mode is corrected to avoid displaying inaccurate estimated running times and optimize the user experience. Garment handling equipment includes washing machines, dryers, and washer-dryer combos.

[0058] Furthermore, factors affecting runtime include garment eccentricity, which can be detected by sensors or calculated by a controller; and operating modes, which include set stages with eccentricity adjustment processes, such as dehydration and drying stages.

[0059] S2 includes S21 to S22, where:

[0060] S21, determine the first duration correction value X1 based on the size of the clothing eccentricity value;

[0061] S22, the estimated running time of the set stage is corrected according to the correction strategy corresponding to the clothing eccentricity value and the first duration correction value X1.

[0062] This embodiment predicts the time required for eccentricity adjustment during the washing process by measuring the eccentricity value of the clothes in advance, and corrects the initial default time based on the predicted time. Before the user starts the washing program, when selecting the washing mode, it can provide the user with an accurate running time, making it convenient for the user to plan the time in advance and improving the user's laundry experience.

[0063] Furthermore, S21 includes:

[0064] The correction level for garment eccentricity is determined based on the magnitude of the garment eccentricity value, and different correction levels correspond to different first duration correction values.

[0065] Among them, the larger the eccentricity value, the higher the correction level, and the higher the corresponding first duration correction value.

[0066] Specifically, S21 includes:

[0067] When the clothing eccentricity value is greater than the first threshold, X1 is A1;

[0068] When the clothing eccentricity value is greater than the second threshold and less than or equal to the first threshold, X1 is B1;

[0069] When the clothing eccentricity value is greater than the third threshold and less than or equal to the second threshold, X1 is C1;

[0070] When the clothing eccentricity value is greater than the fourth threshold and less than or equal to the third threshold, X1 is D1;

[0071] A1>B1>C1>D1.

[0072] In this embodiment, the load inside the drum is divided into four eccentricity levels according to the size of the garment eccentricity value. Different eccentricity levels correspond to different first duration correction values. The larger the garment eccentricity value, the larger the first duration correction value, i.e., A1 > B1 > C1 > D1. The first duration correction value can be a correction duration or a correction percentage. The above A1, B1, C1, and D1 are empirical or experimental values ​​and are not specifically limited.

[0073] Furthermore, this embodiment also provides a parallel implementation of S21. Specifically, S21 further includes steps A1 to A3, wherein:

[0074] A1, compare the clothing eccentricity value with the preset eccentricity value;

[0075] A2, When the clothing eccentricity value is greater than the preset eccentricity value, increase the running time of the setting stage;

[0076] A3. When the clothing eccentricity value is less than the preset eccentricity value, reduce the running time of the setting stage.

[0077] The preset eccentricity value is the default eccentricity threshold in the program. The eccentricity threshold is not unique; different weight classes correspond to different eccentricity thresholds.

[0078] This embodiment adjusts the runtime of the setting stage based on the difference between the clothing eccentricity value and the preset eccentricity value. When the clothing eccentricity value is greater than the preset eccentricity value, the runtime of the setting stage is increased by a corresponding percentage; when the clothing eccentricity value is less than the preset eccentricity value, the runtime of the setting stage is decreased by a corresponding percentage. Furthermore, the range greater than the preset eccentricity value can be refined into two levels, and the range less than the preset eccentricity value can also be refined into two levels.

[0079] Furthermore, factors affecting runtime include detergent type, which can be classified according to foaming characteristics, and other relevant characteristics of detergents, such as detergency and ease of rinsing, can be added for more detailed classification; operating mode includes washing stage;

[0080] S2 includes S23 to S24, where:

[0081] S23, determine the second duration correction value X based on the detergent type;

[0082] S24, the estimated washing time of the washing stage is corrected according to the correction strategy corresponding to the detergent type and the second time correction value.

[0083] This embodiment predicts the duration of the defoaming process and the duration of the eccentricity adjustment during the washing process by measuring the type of detergent and the eccentricity value of the clothes in advance. The initial default duration is corrected by the predicted duration. The system can provide the user with an accurate running time when selecting the washing mode before starting the washing program, so that the user can plan the time in advance and improve the user's laundry experience.

[0084] The method in this embodiment can correct the runtime of the program by measuring the eccentricity value or the detergent type alone, or it can correct the runtime of the program by detecting both the eccentricity value and the detergent type. The addition of multiple factors can achieve more accurate time correction. The order of eccentricity value detection and detergent type identification can be interchanged.

[0085] Furthermore, S23 includes:

[0086] Different types of detergents correspond to different second time correction values; among them, the stronger the foaming ability of the detergent, the larger the corresponding second time correction value.

[0087] Specifically:

[0088] When the detergent type is high-foaming, the second duration correction value is E;

[0089] When the detergent type is medium foam, the second duration correction value is F;

[0090] When the detergent type is low-foaming, the second duration correction value is G; where E > F > G.

[0091] This embodiment categorizes detergents into three types—high-foaming, medium-foaming, and low-foaming—based on their foaming characteristics. When a detergent is identified as high-foaming, the washing time is increased by E% from the default setting; when identified as medium-foaming, the washing time is increased by F%; and when identified as low-foaming, the washing time is increased by G%. The percentage increase X% is obtained through experimental testing. The final washing time equals the default time multiplied by the time increment X%, resulting in the corrected washing time t2.

[0092] Specifically, if the detergent type is not identified after using the method of this embodiment, a default value type, such as "medium foam", is returned to ensure that the program executes smoothly.

[0093] Optionally, the factors affecting washing time include garment eccentricity and detergent type. Based on the values ​​of these factors and the corresponding correction strategies, the preset running time in the operating mode is adjusted.

[0094] t1=t 脱水 ×X1, × represents t 脱水 It is a product relationship with X1; and / or,

[0095] t2=t 洗涤 ×X, × represents t 洗涤 It has a product relationship with X;

[0096] Where t1 represents the corrected dehydration time, t 脱水This indicates the estimated dehydration time, where X1 represents the first time correction value; t2 represents the corrected washing time. 洗涤 X represents the estimated washing time, and X represents the second time correction value. In this embodiment, X1 and X are percentages related to the time correction.

[0097] After calculating t1 and t2, the preset runtime of the entire operating mode is corrected.

[0098] Optionally, the aforementioned first and second duration correction values ​​can also be specific correction durations, which can be positive or negative, and can be increased or decreased based on the original expected running time.

[0099] Furthermore, factors affecting runtime include clothing eccentricity; detection of these factors includes:

[0100] After the clothes are loaded, the washing tub is accelerated according to the set acceleration and the set target speed.

[0101] The magnitude of the clothing eccentricity is determined by the changes in the motor's output during the acceleration process.

[0102] The output of the motor includes, but is not limited to, power.

[0103] Furthermore, the magnitude of the garment's eccentricity is determined based on the changes in the motor's output during the acceleration process, including:

[0104] The magnitude of the clothing eccentricity is determined by the amplitude of the motor power fluctuation.

[0105] The greater the fluctuation in motor power, the greater the eccentricity of the clothing.

[0106] This embodiment provides an eccentricity detection method. The measurement principle of clothing eccentricity is as follows: the drive motor will accelerate to the target speed with a fixed acceleration value. During this process, the fluctuation of motor power is measured. When the clothing material or the weight of a single piece is prone to causing eccentricity, the motor power will fluctuate drastically during acceleration. The corresponding eccentricity value can be calculated based on the amplitude of the power fluctuation.

[0107] Furthermore, factors affecting runtime include detergent type; detection of these factors includes:

[0108] The control panel of the garment processing equipment provides a setting interface for the detergent type, allowing users to input the detergent type.

[0109] This embodiment provides a method for identifying detergent types, combined with... Figure 3There are two ways to obtain the detergent type: one is for the user to scan the detergent packaging with a mobile app and upload it to the cloud, and then identify the detergent type by comparing it with the detergent characteristics in the database; the other is for the user to manually select the detergent type on the washing machine's control panel.

[0110] The main reason for the significant difference between the actual running time and the initial default running time in a washing machine is that the time required for the defoaming process in the washing cycle and the eccentricity adjustment process in the spin-drying cycle is difficult to predict in advance, and the time variation is large. To address this, this embodiment proposes to obtain the detergent type before the user starts the machine, determine the amount of foam during operation, and estimate the defoaming process time; furthermore, after the user adds clothes, eccentricity detection is performed in advance to calculate the eccentricity of the clothes inside the drum and correct the eccentricity correction time in the spin-drying cycle. This allows the user to see the accurate running time before starting the machine, enabling them to adjust according to the actual situation and avoiding a large discrepancy between the displayed and actual running times, which could lead to a poor user experience.

[0111] The flowchart of the runtime correction method in this embodiment is as follows: Figure 2 As shown, the system first determines whether the user has finished loading clothes by checking the door status. When the door is detected as closed, the system identifies the detergent type, distinguishing between high-foam, medium-foam, and low-foam types, and calculates the defoaming cycle time based on the detergent type, along with the total time. Next, it detects the eccentricity of the clothes, and by setting acceleration and a target speed, detects changes in motor power during acceleration to determine the eccentricity of the clothes inside the drum. Based on the eccentricity, it adjusts the eccentricity adjustment cycle time in the spin-drying process, calculates the increment of the spin-drying cycle time, and adjusts the total runtime. Finally, the adjusted time is displayed to the user, allowing them to flexibly adjust the operating mode and schedule washing times based on the accurate adjusted runtime.

[0112] This embodiment modifies the runtime flowchart according to the detergent type, as shown below. Figure 3 As shown, there are two ways to obtain the detergent type: one is by having the user scan the detergent packaging using a mobile app and upload the data to the cloud, then comparing it with detergent characteristics in the database to identify the detergent type; the other is by having the user manually select the detergent type on the washing machine's control panel. In this embodiment, detergents are categorized into three types: high-foaming, medium-foaming, and low-foaming. When a high-foaming detergent is identified, the washing time will increase by E% from the original default time; when a medium-foaming detergent is identified, the washing time will increase by F% from the original default time; and when a low-foaming detergent is identified, the washing time will increase by G% from the original default time. The percentage increase X% is obtained through experimental testing. The final washing time equals the default time multiplied by the time increment X%, resulting in the corrected washing time t2.

[0113] The flowchart of the operation time correction based on clothing eccentricity in this invention is as follows: Figure 4 As shown, the eccentricity of the clothing is measured first. The principle of measuring the eccentricity is as follows: the drive motor accelerates to the target speed at a fixed acceleration value. During this process, the fluctuation of motor power is measured. When the material of the clothing or the weight of a single piece easily causes eccentricity, the motor power will fluctuate drastically during the acceleration process. The corresponding eccentricity value e can be calculated based on the amplitude of the power fluctuation. In this invention, the load inside the drum is divided into four eccentricity levels according to the magnitude of the eccentricity value e. When the eccentricity value e is within the range A, the dehydration process running time is increased by A1%; when the eccentricity value e is within the range B, the dehydration process running time is increased by B1%; when the eccentricity value e is within the range C, the dehydration process running time is increased by C1%; when the eccentricity value e is within the range D, the dehydration process running time is increased by D1%. The above eccentricity values ​​and corresponding increase in time percentage multiplied by 1% are obtained from experimental testing. The final dehydration time is equal to the default time multiplied by the time increment multiplied by 1%, resulting in the corrected time t1.

[0114] After the runtime correction is completed, the user can proceed to the operating mode selection process and start the washing program. This allows users to obtain an accurate runtime when selecting the operating mode, making it convenient for them to adjust the operating mode and schedule washing time as needed. For example, if the user selects the cotton and linen washing mode, the washing machine will remind the user to load the clothes and close the door, and also prompt the user to enter the detergent type. After the user completes these steps, the washing machine will enter the runtime calculation process, completing the calculation within 3-6 seconds and providing feedback to the user.

[0115] The runtime correction scheme for the clothing processing equipment provided in this embodiment avoids the shortcomings of traditional washing machines that first give a default running time and then adjust it according to the actual running situation after startup. This results in the remaining running time being corrected and changed in each running stage, making it impossible for users to obtain an accurate running time and leading to a poor user experience.

[0116] The second aspect of this embodiment discloses a laundry time correction device, the device comprising:

[0117] The detection module is used to detect factors that affect washing time after the user selects the washing machine's operating mode and before the washing machine executes the washing program.

[0118] The correction module is used to correct the preset runtime in the operation mode based on the values ​​of the factors affecting the washing time and the corresponding correction strategies.

[0119] Furthermore, factors affecting washing time include garment eccentricity and / or detergent type; the correction module is also used for:

[0120] A first time-correction value is determined based on the magnitude of the garment eccentricity; and, alternatively, a second time-correction value is determined based on the detergent type; and the preset running time in the operating mode is corrected using the following formula:

[0121] t1=t 脱水 ×X1, × represents t 脱水 It is a product relationship with X1; and / or,

[0122] t2=t 洗涤 ×X, × represents t 洗涤 It has a product relationship with X;

[0123] Where t1 represents the corrected dehydration time, t 脱水 X1 represents the estimated runtime of the dehydration stage, and X2 represents the first time correction value; t2 represents the corrected washing time. 洗涤 This indicates the estimated runtime of the washing phase, with X representing the second duration correction value.

[0124] The third aspect of this embodiment discloses a garment processing apparatus, which employs the method provided in any of the first aspects; or, the garment processing apparatus includes the device provided in the second aspect.

[0125] In the different embodiments provided by this invention, the same parameters, terms, logic, etc. should be understood to have the same meaning, and this application does not intentionally repeat the description in each embodiment.

[0126] Exemplary embodiments of the present disclosure have been specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, arrangements, or implementation methods described herein; rather, the present disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
