Description

Technical Field

[0001] This application relates to the field of fabric processing equipment technology, and more specifically, to a drying control method and fabric processing equipment. Background Technology

[0002] With the increasing demand for energy conservation, environmental protection, and intelligent technology in the home appliance industry, heat pump washing and drying machines have gradually become the mainstream technology solution for high-end washing machines and dryers due to their advantages such as high efficiency, energy saving, and low-temperature drying.

[0003] However, in actual use, users' expectations for equipment performance go beyond basic functions, focusing more on intelligent control capabilities that can accurately adapt to different load conditions. Among these, the determination of heavy loads (such as large items of clothing, multiple items of clothing, or high-density fabrics) has become a key technical challenge in improving equipment energy efficiency, optimizing drying effects, and extending equipment lifespan. Traditional heat pump washing machines mainly rely on temperature sensors to determine the dryness of the load. However, relying solely on sensors has certain limitations. It can easily lead to heavy loads being dried prematurely. Heavy loads of clothing may take longer to dry during the heat exchange process of the heat pump system due to the low efficiency of moisture evaporation. With the development of market demand, users' demand for intelligent washing machines has shifted from "single function realization" to "scenario-based precise control". For example, during the drying stage, the temperature, fan speed or running time can be automatically adjusted according to the type of load.

[0004] However, existing technologies lack the ability to dynamically identify and classify heavy loads, making it difficult for equipment to balance energy efficiency, drying efficiency, and user experience when dealing with complex loads. Summary of the Invention

[0005] This application provides a drying control method and a fabric processing device for a fabric treatment apparatus. The drying control method identifies the thickness level at once using the ratio K of humidity change rate to weight change rate. Based on this, it pre-corrects the initial drying intensity and termination criteria, ensuring that key parameters such as fan frequency and number of drying cycles are adjusted to match the load at the beginning of drying. This prevents heavy fabrics from being prematurely dried or having their drying process prolonged due to "initially low parameters," thereby shortening the overall operating time and reducing energy consumption while ensuring drying uniformity. Specifically: The first aspect of this application provides a drying control method for a fabric processing device, the drying control method comprising: During the drying process, acquire humidity data and load weight data inside the drum; Calculate the humidity change rate ΔH / Δt and the load weight change rate ΔL / Δt inside the cylinder, and adjust the initial dynamic execution quantity and the initial termination criterion quantity according to the ratio K of the humidity change rate ΔH / Δt and the load weight change rate ΔL / Δt. The larger the value of K, the thicker the fabric material. The dynamic execution quantity is used to change the drying intensity, the termination criterion quantity is used to determine when the drying ends, △H represents the humidity change, △t represents the time change, and △L represents the load weight change.

[0006] In the above technical solution, the dynamic execution quantity includes at least the operating frequency of the fan; The termination criterion quantity includes at least the number of termination decisions.

[0007] In the above technical solution, adjusting the dynamic execution quantity and termination criterion quantity based on the ratio K of the humidity change rate △H / △t and the load weight change rate △L / △t includes: When K ≥ the first threshold K1, increase the fan frequency and increase the number of interference checks; When K < the first threshold K1, maintain or reduce the fan frequency and keep the original number of interferences unchanged.

[0008] In the above technical solution, adjusting the dynamic execution quantity and termination criterion quantity based on the ratio K of the humidity change rate △H / △t and the load weight change rate △L / △t includes: When K > 2, the fan frequency increases by 2 Hz to 4 Hz, and the number of interference tests increases by 6 to 10. When 1≤K≤2, the fan frequency increases by 1Hz to 2Hz, and the number of interference detections increases by 3 to 5 times. When K < 1, maintain the fan frequency and keep the original number of interferences unchanged.

[0009] In the above technical solution, the drying control method includes: During the drying process, the humidity and load weight data inside the drum are acquired in real time, and the K value is calculated in real time. The initial dynamic execution quantity and the initial termination criterion quantity are adjusted in real time based on the K value calculated in real time.

[0010] In the above technical solution, the drying control method further includes: While acquiring humidity data and load weight data inside the cylinder, temperature data inside the cylinder is also acquired, and temperature compensation is performed on the humidity data using the temperature data to obtain compensated humidity data. The humidity change rate is calculated based on the compensated humidity data.

[0011] In the above technical solution, the control method further includes: The cumulative additional duration is calculated based on the number of additional intervention attempts determined by the K value. The cumulative additional time and the basic drying time are added together to obtain the initial total drying time; The cumulative additional time = the additional time for a single interception × the number of additional interceptions.

[0012] In the above technical solution, the control method further includes: During the drying process, the remaining drying time is proportionally adjusted based on the initial total drying time and the K value calculated in real time until the remaining drying time reaches zero, at which point the drying process is terminated.

[0013] In the above technical solution, the drying control method further includes: Calculate the rate of change of humidity inside the cylinder between adjacent sampling periods; If the humidity change rate is lower than the preset low-speed change threshold twice in a row, the remaining drying time will be shortened. If the humidity change rate is higher than or equal to the preset low-speed change threshold twice in a row, the remaining drying time will be extended.

[0014] A second aspect of this application provides a fabric processing apparatus that includes the drying control method described above.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The drying control method provided in this application identifies the thickness level at once by using the ratio K of humidity change rate to weight change rate. Based on this, the initial drying intensity and the end criterion are pre-corrected, so that the equipment adjusts key parameters such as "fan frequency and number of drying tests" to match the load at the beginning of drying. This avoids heavy fabrics from being dried prematurely or having their drying process prolonged due to "initially low parameters", thereby shortening the overall running time and reducing energy consumption while ensuring drying uniformity.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0023] To address the problems of existing technologies that rely solely on temperature or fixed drying time to determine the drying progress, leading to misleading "false drying" of thick fabrics and premature shutdown, requiring users to perform secondary drying, high energy consumption, and damage to clothing, this application proposes a solution "based on the humidity-weight dual-variable ratio K as the main line, and gradient intensity-budget duration-two-level correction as the branches." First, in the pre-processing stage, the load thickness is divided into zones using the K value, and the fan frequency and number of drying cycles are immediately adjusted to the corresponding levels. Then, the total drying budget is calculated once by "increasing the number of drying cycles × the additional time per cycle." During operation, the remaining time is continuously corrected using a two-level ratio and threshold based on the real-time K value and the humidity change rate of adjacent cycles, ensuring that the drying intensity and the start-up time always change synchronously with the evaporation curve. This aims to completely eliminate the "outer dry, inner wet" phenomenon and over-drying of thick clothing, achieving energy-efficient and fast drying of thin clothing and thorough drying of thick clothing in one pass under the same program, without requiring users to manually select programs, thus balancing energy saving, high efficiency, and clothing protection.

[0024] Example Specifically, such as Figure 1 As shown, the first aspect of this application provides a drying control method for a fabric processing device, the drying control method comprising: During the drying process, acquire humidity data and load weight data inside the drum; Calculate the humidity change rate △H / △t and the load weight change rate △L / △t inside the drum, and adjust the initial dynamic execution quantity and the initial termination criterion quantity according to the ratio K of the humidity change rate △H / △t and the load weight change rate △L / △t. The larger the K value, the thicker the fabric material. The dynamic execution quantity is used to change the drying intensity, the termination criterion quantity is used to determine when the drying ends, △H represents the humidity change, △t represents the time change, and △L represents the load weight change.

[0025] The drying control method provided in this application identifies the thickness level at once by using the ratio K of humidity change rate to weight change rate. Based on this, the initial drying intensity and the end criterion are pre-corrected, so that the equipment adjusts key parameters such as "fan frequency and number of drying tests" to match the load at the beginning of drying. This avoids heavy fabrics from being dried prematurely or having their drying process prolonged due to "initially low parameters", thereby shortening the overall running time and reducing energy consumption while ensuring drying uniformity.

[0026] It should be noted that the initial dynamic execution quantity = the intensity parameters such as fan frequency and heating power set by the equipment according to the load type or factory default settings before the drying program starts; the initial termination criterion quantity = the preset number of drying cycles, target humidity, or target duration, etc., at the same time. Both are the baseline starting points before the system enters the drying cycle. All subsequent real-time adjustments are offset or proportionally corrected from this baseline to ensure that heavy loads are in the matching gear from zero moment, avoiding premature drying or efficiency loss caused by "gradually climbing from a low gear".

[0027] Furthermore, in some possible implementations, the dynamic execution quantity includes at least the operating frequency of the fan; The number of termination criteria must include at least the number of termination decisions.

[0028] In this embodiment, by defining the "dynamic execution quantity" as the fan operating frequency and the "termination criterion quantity" as the number of drying tests, the drying intensity and termination conditions are given a direct and immediate control lever: the fan frequency can be steplessly adjusted to adjust the rate of hot and humid air replacement in the cylinder, and the number of drying tests can be simply accumulated to complete the termination judgment. Both rely on existing sensors and frequency conversion hardware, and can be pre-corrected immediately after heavy load is identified without additional cost, thereby avoiding premature drying and over-drying in one go, and achieving precise drying with high efficiency, low consumption and zero rework.

[0029] Furthermore, in some possible implementations, the dynamic execution quantity and termination criterion quantity are adjusted according to the ratio K of the humidity change rate ΔH / Δt and the load weight change rate ΔL / Δt, including: When K ≥ the first threshold K1, increase the fan frequency and increase the number of interference checks; When K < the first threshold K1, maintain or reduce the fan frequency and keep the original number of interferences unchanged.

[0030] In this embodiment, the heavy load is separated from the continuous spectrum at a single point using the comparison "K≥first threshold K1", and immediately given the pre-action of "frequency increase + number of times": after the fan frequency is increased, the exchange rate of humid and hot air inside the drum increases accordingly, and the moisture gradient between the surface and the interior of the heavy fabric is quickly leveled out; simultaneously increasing the number of drying judgments allows for dense sampling even in the evaporation deceleration phase, preventing premature termination due to "false drying". Compared to a one-size-fits-all program without partitions, this threshold judgment allows the equipment to enter the intensity level matching the thickness grade at the beginning of drying, which shortens the overall running time and reduces the probability of re-drying and energy consumption.

[0031] Furthermore, in some possible implementations, the dynamic execution quantity and termination criterion quantity are adjusted according to the ratio K of the humidity change rate ΔH / Δt and the load weight change rate ΔL / Δt, including: When K > 2, the fan frequency increases by 2 Hz to 4 Hz, and the number of interference tests increases by 6 to 10. When 1≤K≤2, the fan frequency increases by 1Hz to 2Hz, and the number of interference detections increases by 3 to 5 times. When K < 1, maintain the fan frequency and keep the original number of interferences unchanged.

[0032] In this embodiment, the three ranges of "large, medium, and small K values" are directly mapped to specific levels of fan frequency increment and drying cycle increment, forming a gradient-type pre-compensation. Specifically, in the heavy drying range (K>2), the airflow is increased first, followed by intensive drying to quickly remove deep moisture and avoid "dry outside, wet inside." In the medium drying range (1≤K≤2), medium airflow and moderate drying are used, balancing efficiency and accuracy. Through zoned incremental assignment, the equipment can output an intensity-duration combination that matches the load thickness at the start of drying, eliminating the defect of "incomplete drying and premature shutdown" caused by insufficient initial parameters for heavy clothing in one step, achieving efficient, low-rework, and low-energy-consumption precise drying.

[0033] Furthermore, in some possible implementations, the drying control method includes: During the drying process, the humidity and load weight data inside the drum are acquired in real time, and the K value is calculated in real time. The initial dynamic execution quantity and the initial termination criterion quantity are adjusted in real time based on the K value calculated in real time.

[0034] This application's embodiment introduces a full-cycle closed loop based on the "one-time pre-correction": the K value is continuously refreshed during the drying process, and the initial parameters such as fan frequency and number of drying cycles are dynamically readjusted accordingly. This allows the system to instantly increase the frequency or intensify drying cycles when the load moisture gradient changes over time, avoiding misjudgments caused by "drying thicker clothes first and then thinner ones" or "drying some areas prematurely." Furthermore, there is no need to wait for the next drying cycle; adaptive correction can be performed within the same program, reducing the probability of mid-cycle shutdowns or re-drying. Simultaneously, parameters are kept synchronized with the evaporation state throughout the process, completing the simultaneous drying of heavy clothing inside and out in the shortest possible net time, further reducing energy consumption and wear.

[0035] Furthermore, in some possible implementations, the drying control method further includes: While acquiring humidity data and load weight data inside the cylinder, temperature data inside the cylinder is also acquired, and temperature compensation is performed on the humidity data using the temperature data to obtain compensated humidity data. The humidity change rate is calculated based on compensated humidity data.

[0036] In this embodiment, temperature data is introduced simultaneously outside the humidity channel. After temperature compensation, compensated humidity data is obtained, and the humidity change rate is calculated using this compensated value. The technical effect is to eliminate humidity reading deviations caused by temperature drift, making ΔH / Δt more accurately reflect the amount of moisture evaporation. This allows the K-value judgment and subsequent adjustments to the fan frequency and drying times to be based on accurate evaporation information, avoiding premature drying due to falsely low humidity in high-temperature environments, and ensuring accurate drying endpoints for heavy loads, preventing over-drying and rework.

[0037] Specifically, the aforementioned temperature compensation includes at least: establishing a humidity-temperature characteristic curve, correcting the measured humidity value using a lookup table method or a polynomial fitting method, and eliminating measurement errors caused by temperature drift.

[0038] Furthermore, in some possible implementations, the control method further includes: The cumulative additional duration is calculated based on the number of additional intervention attempts determined by the K value. The cumulative additional time and the basic drying time are added together to obtain the initial total drying time; The cumulative additional time = the additional time for a single interception × the number of additional interceptions.

[0039] In this embodiment, the "increased number of drying tests" is directly converted into a quantifiable cumulative additional time, which is then added to the basic drying time to form the initial total drying time. The technical advantage is that the additional evaporation time required for heavy loads is calculated all at once using a linear scale of "number of tests × single drying time," avoiding the repeated shutdowns of traditional methods that require "additional drying if the load isn't completely dry." Simultaneously, it provides a clear time benchmark for subsequent real-time adjustments, enabling the system to carry a "dedicated time budget for heavy clothing" from startup, shortening the total operating cycle and reducing energy consumption and wear while ensuring thorough drying.

[0040] Furthermore, in some possible implementations, the control method further includes: During the drying process, the remaining drying time is proportionally adjusted based on the initial total drying time and the K value calculated in real time until the remaining drying time reaches zero, at which point the drying program is terminated.

[0041] In this embodiment, the "initial total drying time" is used as the time budget, and the remaining time is proportionally corrected using the real-time K value. This allows heavy loads to automatically gain extra time during the evaporation deceleration phase, while light loads are dried earlier. This avoids over-drying or re-drying caused by a "one-size-fits-all" approach to the drying time, thus achieving closed-loop control of "thick clothes drying thoroughly and thin clothes saving energy".

[0042] Furthermore, in some possible implementations, the drying control method further includes: Calculate the rate of change of humidity inside the cylinder between adjacent sampling periods; If the humidity change rate is lower than the preset low-speed change threshold twice in a row, the remaining drying time will be shortened. If the humidity change rate is higher than or equal to the preset low-speed change threshold twice in a row, the remaining drying time will be extended.

[0043] In this embodiment, the remaining time is corrected a second time by using the "adjacent cycle humidity change rate" to form an evaporation rate-time negative feedback: when the humidity decrease slows down continuously, it indicates that evaporation is nearing its end, and the system immediately shortens the remaining time to prevent over-drying; when the humidity decrease is still rapid, the time is extended to ensure that the moisture inside thick clothing is completely migrated. Thus, on the basis of proportional correction, a speed threshold correction is added, so that the total drying time is synchronized with the K value trend and closely follows the real-time evaporation rhythm, the endpoint judgment is more accurate, and the overall energy consumption is further reduced.

[0044] In summary, the drying control method provided in this application constructs a closed loop from four levels: "identification, intensity, duration, and endpoint." First, the thickness level is determined once using the ratio of humidity to weight change rate K, with real-time frequency increase and intensified drying judgment to ensure matching of initial intensity. Then, the total time is linearly estimated using "number of drying judgments × single additional duration," with proportional correction added to dynamically adjust the duration according to the evaporation trend. Finally, a secondary correction is performed using the humidity change rate of adjacent cycles to accurately capture the deceleration inflection point and prevent over-drying. The entire solution requires no additional hardware, requires zero manual program selection, and achieves fast drying and energy saving for thin clothing, thorough drying of heavy clothing in one pass, zero re-drying, and low wear, comprehensively improving the intelligence, compatibility, and energy efficiency of fabric processing equipment.
