Description

Technical Field

[0001] This application belongs to the field of smart home appliance technology, specifically relating to a method, apparatus, equipment, and storage medium for drying clothes. Background Technology

[0002] As consumers increasingly prioritize clothing quality, more and more are choosing to purchase garments made from easily deformable materials like wool. These garments require precise drying, so to avoid damage, consumers often take them to dry cleaners. However, this increases the waste of consumers' resources.

[0003] To address the aforementioned issue of user resource consumption, existing technologies include a drying program specifically designed for easily deformable clothing. During the drying process, the reversible rotation of the inner drum used to shake out clothes is eliminated. Instead, the inner drum rotates at a low speed in one direction, causing the easily deformable clothing to adhere to the drum and rotate with it, thus achieving even distribution. Simultaneously, a humidity sensor acquires the humidity level of the easily deformable clothing, and the drying time is determined based on the humidity.

[0004] However, due to the rotation of the drying drum on garments made of easily deformable materials, the drying effect of hot air on the garment is uneven, resulting in different humidity levels on different sides of the garment. Since the humidity sensor only detects the humidity on one side of the garment, directly judging dryness based on the measured humidity may lead to over-drying of easily deformable materials, thereby damaging the garment material. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this application provides a method, apparatus, device, and storage medium for drying clothes.

[0006] In a first aspect, this application provides a method for drying clothes, the method comprising:

[0007] When the type of clothing to be dried is the target type, the clothing to be dried is dried using a preset mode. In the preset mode, the inner drum of the clothing processing equipment rotates at a preset speed and in a preset direction.

[0008] During the drying process of the clothes to be dried, the load eccentricity change rate of the inner drum is obtained;

[0009] Based on the load eccentricity change rate within the set first time window, it is determined whether the drying stop condition is met; the load eccentricity change rate is used to characterize the degree of drying of the clothes;

[0010] When the conditions for stopping the drying process are met, the garment processing equipment is controlled to stop operating.

[0011] In one possible implementation, obtaining the load eccentricity change rate of the inner cylinder includes:

[0023] The second time window is moved according to the preset first sliding step size, and the steps of obtaining the load eccentricity change rate are repeated.

[0024] In one possible implementation, determining whether the drying stop condition is met based on the load eccentricity change rate within a set first time window includes:

[0025] The threshold of the eccentricity change rate is obtained from the multiple load eccentricity change rates acquired.

[0026] The target load eccentricity change rate is obtained based on the average load eccentricity change rate within the first time window.

[0027] Determine whether the target load eccentricity change rate is less than the eccentricity change rate threshold;

[0028] If so, then the conditions for stopping drying are met;

[0029] If not, the first time window is moved according to the preset second sliding step size, and the step of obtaining the target load eccentricity change rate is repeated until the re-obtained target load eccentricity change rate is less than the eccentricity change rate threshold.

[0030] In one possible implementation, obtaining the eccentricity change rate threshold based on the acquired multiple load eccentricity change rates includes:

[0031] Obtain the comparison coefficients;

[0032] The load eccentricity change rate with the largest value is obtained from the plurality of load eccentricity change rates, and the eccentricity change rate threshold is obtained by multiplying the comparison coefficient and the load eccentricity change rate with the largest value.

[0033] In one possible implementation, obtaining the comparison coefficient includes:

[0034] The weight of the clothes to be dried is obtained, and the comparison coefficient is obtained from the mapping relationship obtained from the pre-experiment based on the weight of the clothes. The mapping relationship is used to indicate the correspondence between the weight of the clothes and the comparison coefficient under the preset mode.

[0039] The control module is also used to control the clothing processing equipment to stop operating when the drying stop conditions are met.

[0040] Thirdly, this application also provides a garment processing device, comprising: at least one processor and a memory, wherein:

[0041] The memory is used to store computer-executed instructions;

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0055] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0056] For garments made of easily deformable materials like wool, existing garment processing equipment employs specific drying programs. During the drying process, the reversible rotation of the inner drum used to shake and disperse the garments is eliminated. Instead, the inner drum rotates at a low speed in one direction, causing the easily deformable garments to adhere to the drum and rotate with it, thus achieving even distribution. Simultaneously, a humidity sensor acquires the humidity of the easily deformable garments and determines the dryness level based on this data. However, because the easily deformable garments are attached to the drum and rotate, the drying effect of the hot air is uneven, resulting in different humidity levels on different sides of the garment. Since the humidity sensor only detects the humidity on one side of the garment, directly determining the dryness level based on this data may lead to over-drying of the easily deformable garments, thereby damaging the fabric.

[0057] This application provides a method for drying clothes. When the clothes processing equipment dries clothes according to a preset mode, it calculates the load eccentricity change rate of the inner drum and determines whether drying is complete based on the load eccentricity change rate within a first time window. This method allows for the determination of whether clothes are dry without damaging the fabric.

[0058] Next, the technical solutions shown in this application will be described in detail through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and the same or similar content will not be described again in different embodiments.

[0059] It should be noted that because the target type of clothing needs to rotate with the inner drum of the garment handling equipment during the drying process to achieve a close-fitting effect, the garment handling equipment must provide sufficient rotation speed to achieve the aforementioned effect. For example, the garment handling equipment can be a drum washing machine with a drying function.

[0060] Figure 1 A schematic flowchart of a clothes drying method provided in this application embodiment. Figure 1 .like Figure 1 As shown, the method includes:

[0061] S101. When the type of clothing to be dried is the target type, the preset mode is used to dry the clothing.

[0062] In the preset mode, the inner drum of the garment processing equipment rotates at a preset speed and in a preset direction.

[0063] In this step, wool fibers are relatively fragile and easily damaged by stretching, friction, and compression. Therefore, if wool garments are subjected to strong shaking during the drying process, the bond structure between the fibers may be broken, leading to deformation, shrinkage, or pilling.

[0064] Clothing processing equipment removes moisture from clothing using high-temperature air and a rotating drum. Under the combined effects of high temperature and rotation, the clothing is shaken to facilitate moisture evaporation. However, this intense shaking and hot air can cause thermal damage and mechanical abrasion to wool fibers. With increasing demand for high-quality clothing, wool-like fabrics are becoming more common, and drying these types of clothing using clothing processing equipment can damage them. Therefore, this embodiment sets up a preset program suitable for drying the target type of clothing and makes judgments based on this preset program.

[0065] Specifically, when the clothing processing equipment receives a drying request and determines that the clothing to be dried is the target type based on the drying request, it retrieves a preset model and dries the clothing to be dried using the preset mode.

[0066] S102. During the drying process of clothes to be dried, obtain the load eccentricity change rate of the inner drum.

[0067] In this step, the clothes to be dried using the preset program will adhere to the inner drum wall and rotate with the inner drum. At the same time, because the rotation speed of the inner drum is relatively low, the clothes to be dried will not move relative to the inner drum, thus the magnitude of the load eccentricity of the inner drum is affected by the weight of the clothes to be dried.

[0068] Furthermore, considering that the preset program does not use forward and reverse shaking to disperse the clothes, ensuring that only one side of the clothes to be dried is directly exposed to the hot air from the garment processing equipment, if a humidity sensor is used to detect the humidity of the clothes to be dried and then determine whether the clothes are dry enough, the humidity reading might be different depending on the location of the humidity sensor. This could result in the clothes being over-dried or under-dried. Therefore, this embodiment determines whether the clothes are dry by observing the eccentric load change of the inner drum during the drying process.

[0069] Specifically, during the drying process of the clothing processing equipment, the load eccentricity of the inner drum is intermittently collected, and the load eccentricity change rate of the inner drum is calculated based on multiple load eccentricities obtained according to a preset collection cycle. Furthermore, considering that the load eccentricity indicates the degree of inner drum offset, the value of the load eccentricity is relatively small. To facilitate observation and subsequent calculations, the load eccentricity change rate can be amplified when calculating it.

[0070] S103. Determine whether the drying stop condition is met based on the load eccentricity change rate within the set first time window; the load eccentricity change rate is used to characterize the degree of drying of the clothing.

[0071] In this step, further considering the preheating stage of the drying process in the clothing processing equipment, the drying of the clothes to be dried is slower in this stage, meaning less moisture evaporates. This results in a smaller change in the load eccentricity of the inner drum during intermittent drying. In other words, the load eccentricity change rate is small in the early stage of the drying process. As the inner drum of the clothing processing equipment completes preheating and the drying temperature rises, the humidity change of the clothes to be dried is larger over the same period. Therefore, the load eccentricity change rate is larger in the middle stage of the drying process. As the humidity of the clothes to be dried decreases and they approach the finished drying state, the humidity change gradually decreases and approaches zero. Therefore, the load eccentricity change rate gradually decreases and tends towards zero in the later stage of the drying process.

[0072] Therefore, it can be determined that when the clothing processing equipment dries the clothes according to the preset mode, the change process of the load eccentricity change rate of the inner drum is: from small to large, then small again until it approaches 0 in the later stage. It can be seen that the values ​​of the eccentricity change rate of the inner drum are relatively close in the early and late stages of the drying process. If the drying equipment is directly determined to have completed drying based on only a single or multiple eccentricity change rates within a small time range, misjudgment may occur. To avoid the aforementioned misjudgment, this embodiment comprehensively judges whether the drying stop condition is met based on multiple load eccentricity change rates within a certain time range.

[0073] However, considering that the clothes to be dried are of a specific type, namely, clothes made of sensitive materials such as wool or silk, there are strict requirements on the drying time. To make the process of determining whether the drying stop condition is met by comprehensively considering multiple load eccentricity change rates within a certain time range more accurate and timely, this embodiment sets a time window and performs sliding judgment based on the load eccentricity change rate within the time window.

[0074] Specifically, a first time window is set. To reduce the number of judgments, the first time window can be determined based on the preheating time of the garment processing equipment. Multiple load eccentricity change rates within the first time window are pre-processed, for example, by calculating the average value. Judgments are then made based on the load eccentricity change rate obtained after the pre-processing.

[0075] S104. When the conditions for stopping the drying are met, control the clothing processing equipment to stop operating.

[0076] In this step, when the load eccentricity change rate within the first time window is determined to meet the conditions for stopping drying, the clothing processing equipment is controlled to stop operating.

[0077] This application provides a method for drying clothes. When the clothes processing equipment dries clothes according to a preset mode, it calculates the load eccentricity change rate of the inner drum and determines whether drying is complete based on the load eccentricity change rate within a first time window. This method allows for the determination of whether clothes are dry without damaging the fabric.

[0078] Figure 2 A schematic flowchart of a clothes drying method provided in this application embodiment. Figure 2 This embodiment provides a detailed explanation of how to calculate the rate of change of load eccentricity. For example... Figure 2 As shown, the method includes:

[0079] S201. Collect the initial load eccentricity of the inner cylinder according to the preset sampling interval, and filter the initial load eccentricity to obtain the corresponding load eccentricity.

[0080] In this step, the clothes to be dried in the preset program rotate on the inner drum, and the inner drum rotates at a relatively low speed, so the inner drum hardly shifts. The magnitude of the load eccentricity is affected by the weight of the clothes to be dried. However, considering that the inner drum may suddenly shift during the drying process due to other external factors, if the load eccentricity is collected at this time, the obtained load eccentricity will be abnormal and the value will be large. Therefore, in order to make the judgment more accurate, this embodiment performs filtering processing after reading the initial load eccentricity.

[0081] Furthermore, considering that the load eccentricity of the inner cylinder does not change significantly in a short period of time, when the initial load eccentricity is sufficient, the initial load eccentricity collected in this instance can be filtered based on the previously preset number of initial load eccentricities and the initial load eccentricity collected in this instance to obtain the corresponding load eccentricity. The specific process is as follows:

[0082] The initial load eccentricity of the inner cylinder is collected according to a preset sampling interval, which can be 30 seconds or 1 minute. The acquisition order corresponding to each initial load eccentricity is obtained according to the acquisition time. Finally, it is determined whether the acquisition order corresponding to each initial load eccentricity is greater than a preset order.

[0083] If not, then obtain the corresponding load eccentricity based on the initial load eccentricity corresponding to the acquisition order;

[0084] If so, the corresponding load eccentricity is obtained based on the minimum value among the preset number of initial load eccentricities before the acquisition order and the initial load eccentricities corresponding to the acquisition order.

[0085] For example, the initial load eccentricity sets obtained in the order of acquisition from front to back are: initial load eccentricity a: 30mm, initial load eccentricity b: 30mm, initial load eccentricity c: 29.5mm, initial load eccentricity d: 29.3mm, initial load eccentricity e: 29.25mm, initial load eccentricity f: 30.1mm, with a preset order of 4 and a preset quantity of 3.

[0086] Since the order in which the first four initial load eccentricities are obtained is less than or equal to the preset number of 4, the load eccentricity a corresponding to initial load eccentricity a is 30mm, the load eccentricity b corresponding to initial load eccentricity b is 30mm, the load eccentricity c corresponding to initial load eccentricity c is 29.5mm, and the load eccentricity d corresponding to initial load eccentricity d is 29.3mm.

[0087] Since the initial load eccentricity e and initial load eccentricity f are obtained in a sequence greater than the preset order 4, the load eccentricity e corresponding to the initial load eccentricity e is the minimum value among the three initial load eccentricities and the initial load eccentricity e obtained before the initial load eccentricity e. In other words, it is the minimum value among the initial load eccentricities b, c, d, and e, which is 29.25mm. Similarly, the load eccentricity f corresponding to the initial load eccentricity f is 29.25mm.

[0088] S202. From the multiple load eccentricities within the second time window, obtain the first load eccentricity with the largest value and the second load eccentricity with the smallest value.

[0089] In this step, considering that the clothes to be dried are of a specific type and require a relatively high drying temperature (i.e., the drying temperature cannot be too high), the humidity of the clothes decreases slowly, resulting in a slower change in load eccentricity. Therefore, the second time window selected for calculating the rate of change of load eccentricity should not be too short, and the number of load eccentricities within the second time window should be sufficient. For example, considering that the change in load eccentricity of the inner drum is small during the initial preheating stage of the drying process, the second time window can be obtained based on the preheating time.

[0090] Specifically, the values ​​of multiple load eccentricities in the second time window are compared, and the first load eccentricity with the largest value and the second load eccentricity with the smallest value are obtained.

[0091] S203. Obtain the eccentricity difference between the first load eccentricity and the second load eccentricity, and obtain the load eccentricity change rate based on the ratio of the eccentricity difference to the first load eccentricity.

[0092] In this step, the eccentricity difference is obtained based on the difference between the first load eccentricity and the second load eccentricity. Then, the load eccentricity change rate is obtained based on the ratio of the eccentricity difference to the first load eccentricity. For easier observation, the obtained load eccentricity change rate can be magnified by a preset factor, for example, 10 times.

[0093] For example, the load eccentricity set is: 30, 30, 29.5, 29.3, 29.25, 29.25, 29.1, 29.05, 28.9, 28.85, 28.6, 28.4, 28.31, 28.25, 28.2, 28.05, 27.9, 27.8, 27.5, 27.2, 27.0, 26.5, 26.3. The second time window is 20, with an interval of 1 minute and a magnification of 100.

[0094] The number of load eccentricities within each second time window is calculated based on the second time window and the interval, resulting in 20 / 1 = 20 eccentricities. The load eccentricities within the second time window are then obtained from the load eccentricity set, resulting in 20 load eccentricities: 30, 30, 29.5, 29.3, 29.25, 29.25, 29.1, 29.05, 28.9, 28.85, 28.6, 28.4, 28.31, 28.25, 28.2, 28.05, 27.9, 27.8, 27.5, and 27.2. The first load eccentricity is 30 mm, and the second load eccentricity is 27.2 mm. The eccentricity difference is calculated to be 30 - 27.2 = 2.8 mm. The amplified load eccentricity change rate is calculated as: (eccentricity difference / first load eccentricity) × amplification factor = (2.8 / 30) × 100 = 9.3.

[0095] S204. Move the second time window according to the preset first sliding step size, and repeat the step of obtaining the load eccentricity change rate.

[0096] In this step, after the load eccentricity change rate is calculated for the first time based on the load eccentricity within the second time window, the second time window is moved according to a preset first sliding step size, and the step of obtaining the load eccentricity change rate is repeated. For example, the first sliding step size is 1.

[0097] This application provides a method for drying clothes. The method involves periodically collecting initial load eccentricity data within the drying drum, filtering the data to obtain the corresponding load eccentricity, and then, when the running time meets a second time window, calculating the load eccentricity change rate based on the load eccentricity within that second time window. The second time window is then slid along a first sliding step size, and the process of acquiring the load eccentricity change rate is repeated. This method makes the obtained load eccentricity more stable and the calculated load eccentricity change rate more accurate.

[0098] Figure 3 A schematic flowchart of a clothes drying method provided in this application embodiment. Figure 3 This embodiment provides a detailed explanation of how to determine whether the drying stop condition is met based on the rate of change of load eccentricity within the first window time. For example... Figure 3 As shown, the method includes:

[0099] S301. Based on the average load eccentricity change rate within the first time window, obtain the target load eccentricity change rate, and obtain the eccentricity change rate threshold based on the obtained multiple load eccentricity change rates.

[0100] In this step, to avoid misjudging that the clothing processing equipment meets the conditions for stopping drying due to the load eccentricity change rate during the preheating stage, this embodiment sets a first time window and makes a comprehensive judgment based on multiple load eccentricity change rates within the first time window.

[0101] Furthermore, based on prior experiments, the load eccentricity threshold indicating the completion of drying of the clothes to be dried is related to the largest obtained load eccentricity change rate. Therefore, in this embodiment, the eccentricity change rate threshold is obtained based on the maximum value among multiple obtained load eccentricity change rates. The specific operation is as follows:

[0102] The weight of the clothes to be dried is obtained, and the comparison coefficient is obtained from the mapping relationship obtained from the pre-experiment based on the weight of the clothes, wherein the mapping relationship is used to indicate the correspondence between the weight of the clothes and the comparison coefficient in the preset mode;

[0103] The load eccentricity change rate with the largest value is obtained from the plurality of load eccentricity change rates, and the eccentricity change rate threshold is obtained by multiplying the comparison coefficient and the load eccentricity change rate with the largest value.

[0104] Furthermore, after obtaining the eccentricity change rate threshold, the target eccentricity change rate is obtained based on the average load eccentricity change rate within the first time window.

[0105] S302. Determine whether the target load eccentricity change rate is less than the eccentricity change rate threshold.

[0106] Furthermore, after determining the target load eccentricity change rate and the eccentricity change rate threshold, the relationship between the target load eccentricity change rate and the eccentricity change rate threshold is obtained, and based on the obtained relationship, it is determined whether the clothing processing equipment meets the conditions for stopping drying.

[0107] S303. If so, then the drying stop condition is met.

[0108] In this step, it is considered that if the drying stop condition is met, it means that the load eccentricity change rate is small. Therefore, when it is determined that the target load eccentricity change rate is less than the eccentricity change rate threshold, it means that the primary garment processing equipment meets the drying stop condition, and the garment processing equipment is controlled to stop drying.

[0109] S304. If not, move the first time window according to the preset second sliding step size, and repeat the step of obtaining the target load eccentricity change rate until the re-obtained target load eccentricity change rate is less than the eccentricity change rate threshold.

[0110] In this step, when the target load eccentricity change rate is determined to be greater than or equal to the eccentricity threshold, it indicates that the clothing processing equipment does not meet the requirements for stopping drying. Therefore, it is necessary to move the first time window according to the second sliding step size and repeat the steps of calculating the target load eccentricity change rate and determining whether the drying stop condition is met.

[0111] Furthermore, considering that the clothes to be dried are quite sensitive, it is necessary to control the clothes processing equipment to stop operating in a timely manner. Therefore, the first sliding step size is generally taken as 1.

[0112] This application provides a method for drying clothes, which involves obtaining a threshold for the rate of change of eccentricity, and when the running time of the clothes processing equipment meets a first time window, obtaining the relationship between the average value of the load eccentricity change rate within the first time window and the threshold for the rate of change of eccentricity change, and determining whether the drying condition is met based on the relationship; alternatively, the first time window can be slid, and the steps of calculating the target load eccentricity change rate and making the determination can be repeated. Through this method, the clothes processing equipment can be controlled to stop drying in a timely manner, avoiding damage to the clothes to be dried.
