[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 2024110668817, filed on August 5, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This specification relates to the field of washer-dryer combos, and more specifically, this application relates to a drying control method and related equipment for a washer-dryer combo. Background Technology

[0004] A washer-dryer combo is a garment processing device that combines washing and drying functions. In related technologies, the drying temperature is approximately 75-85℃. High-temperature drying often damages soft materials such as silk, affecting their natural luster. At the same time, due to insufficient accuracy in judging dryness, it often leads to uneven drying or over-drying.

[0005] In order to at least solve some of the above problems, there is an urgent need to provide a more gentle and suitable drying control method for washer-dryer combos for soft materials such as silk. Summary of the Invention

[0006] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary section is not intended to limit the key and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] Firstly, this application proposes a drying control method for a washer-dryer combo, including:

[0008] The clothes to be treated are dehydrated by the continuous rotation of the drum.

[0009] The above-mentioned clothes to be treated are shaken apart by the reverse rotation of the above-mentioned rollers after dehydration.

[0010] The aforementioned drying device dries the shaken-out clothes, wherein the aforementioned drying device includes a heating device and a fan;

[0011] The dryness is determined by an exhaust temperature measuring device;

[0012] When the exhaust temperature measuring device indicates that the clothes are dry, the drying device performs supplementary drying on the clothes to be treated.

[0013] In one feasible implementation, it further includes:

[0014] The disconnection temperature of the heating device corresponding to the above-mentioned drying and the above-mentioned supplementary drying is 35 degrees Celsius to 45 degrees Celsius, and the start-stop temperature difference of the heating device is 3 degrees Celsius to 6 degrees Celsius.

[0015] In one feasible implementation, when the exhaust temperature measuring device indicates that the garment is dry, the drying device performs supplementary drying on the garment to be treated, including:

[0016] When the exhaust temperature indicated by the exhaust temperature measuring device is dry, the first dynamic time supplement is determined based on the working time of the drying device when the exhaust temperature is dry and the first time supplement coefficient corresponding to the exhaust temperature indication being dry.

[0017] The aforementioned drying device is used to perform time-added drying of the aforementioned clothing to be processed for the aforementioned first dynamic time-added time.

[0018] In one feasible implementation, when the exhaust temperature measuring device indicates that the garment is dry, the drying device performs supplementary drying on the garment to be treated, including:

[0019] When the exhaust temperature change rate indicated by the exhaust temperature measuring device is dry, the second dynamic time supplement is determined based on the working time of the drying device and the second time supplement coefficient corresponding to the exhaust temperature change rate indicated dry.

[0020] The aforementioned drying device is used to perform time-added drying of the aforementioned clothing to be treated using the aforementioned second dynamic time-added time.

[0021] In one feasible implementation, when the exhaust temperature indicator is dry, the difference between the exhaust temperature value within a preset time period and the reference temperature is less than a preset difference, and the reference temperature is determined based on the average value of the drying device's disconnection temperature and start-stop temperature difference.

[0022] In one feasible implementation, when the exhaust temperature change rate indicator is dry, the slope of the temperature change corresponding to the exhaust temperature is less than a preset slope.

[0023] In one feasible implementation, determining the first dynamic time supplement based on the operating time of the drying device when the exhaust temperature indicator indicates dryness and the first time supplement coefficient corresponding to the exhaust temperature indicator indicates dryness includes:

[0024] The first dynamic time supplement is determined by multiplying the working time of the drying device when the exhaust temperature indicator indicates dryness by the first time supplement coefficient corresponding to the exhaust temperature indicator dryness.

[0025] In one feasible implementation, determining the second dynamic time supplement based on the operating time of the drying device when the exhaust temperature change rate indicates dryness and the second time supplement coefficient corresponding to the exhaust temperature change rate indication dryness includes:

[0026] The second dynamic time supplement is determined by multiplying the working time of the drying device when the exhaust temperature change rate indicator is dry by the second time supplement coefficient corresponding to the exhaust temperature change rate indicator.

[0027] In one feasible implementation, the first time supplement factor is 0.2 to 0.8.

[0028] In one feasible implementation, the second time supplement coefficient is 0.1 to 0.6.

[0029] In one feasible implementation, when the clothes to be treated are dehydrated by the continuous rotation of the drum, the corresponding rotation speed of the drum is 600 to 800 revolutions per minute.

[0030] In one feasible implementation, the above-mentioned shaking of the dehydrated garments by reversing the rotation of the roller includes:

[0031] The aforementioned roller rotates in a first direction during the first cycle;

[0032] The aforementioned roller stops rotating during the second cycle;

[0033] The aforementioned roller rotates in the second direction during the third cycle.

[0034] In one feasible implementation, the drying of the shaken clothing by the drying device includes:

[0035] Start the aforementioned fan of the drying device;

[0036] After the fan has run for the fourth cycle, the heating device of the drying unit is activated to dry the shaken clothes.

[0037] In one feasible implementation, the above method further includes:

[0038] At the end of the aforementioned time-added drying process, the heating device should be turned off first.

[0039] The aforementioned fan is kept running until the fifth cycle of the aforementioned heating device is shut down, after which it is turned off.

[0040] In a second aspect, an electronic device includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program stored in the memory to implement the steps of the washer-dryer control method of any of the first aspects described above.

[0041] Thirdly, this application also proposes a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the drying control method for a washer-dryer combo according to any one of the first aspects.

[0042] Fourthly, this application also proposes a garment handling device, including the electronic equipment of the second aspect.

[0043] In summary, the washer-dryer control method proposed in this application includes: continuously rotating the drum to dehydrate the clothes; rotating the drum in the opposite direction to shake the dehydrated clothes; drying the shaken clothes using a drying device, which includes a heating device and a fan; determining dryness using an exhaust temperature measuring device; and performing supplementary drying on the clothes when the exhaust temperature measuring device indicates dryness. The low-temperature drying operation proposed in this application controls the drying temperature within a lower range (e.g., 35-45°C), lower than traditional high-temperature drying. This helps protect the fiber structure of soft materials such as silk, reducing damage caused by high temperatures, such as fiber embrittlement and color distortion, while maintaining the natural luster of the clothes. The shaking operation using the drum's reverse rotation effectively disperses the clothes, preventing them from clumping together during drying. This not only improves drying uniformity but also speeds up the drying process and increases energy efficiency. Using data from the exhaust temperature measuring device to accurately determine the degree of dryness avoids the inaccurate dryness determination common in traditional drying methods. Accurate drying time determination ensures that drying stops promptly once clothes reach the ideal dryness, avoiding energy waste and damage caused by over-drying. When the exhaust temperature meets the drying time determination criteria, dynamic time-addition drying adjusts the drying time based on the actual dryness of the clothes, ensuring both effective drying and improved energy efficiency.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0050] Please see Figure 1 The drying control method for a washer-dryer combo provided in this application embodiment may specifically include:

[0051] S110. The clothes to be treated are dehydrated by the continuous rotation of the drum.

[0052] For example, washer-dryer combos use the continuous rotation of the drum to spin-dry clothes at a low speed. The main purpose of this low-speed spin-drying is to remove as much water as possible from the clothes through physical force (centrifugal force), but at a low speed to avoid damaging the clothes.

[0053] S120. The dehydrated clothes are shaken apart by the reverse rotation of the above-mentioned roller.

[0054] For example, the clothes to be treated after low-speed dehydration are shaken apart by rotating the drums in the opposite direction of the gap. The purpose of this step is to loosen the clothes and prevent them from sticking together, thus better preparing them for the subsequent drying step.

[0055] S130. The above-mentioned clothes to be processed after being shaken are dried by the above-mentioned drying device, wherein the above-mentioned drying device includes a heating device and a fan.

[0056] For example, a drying device is used to dry the clothes after the shaking operation at a low temperature. Low-temperature drying helps protect the fibers of the clothes from high-temperature damage, while effectively removing excess water from the clothes. The drying device includes a heating element and a fan. The heating element is used to increase the temperature, and the fan is used to accelerate the airflow. Through the coordinated work of the heating element and the fan, the clothes can be dried quickly.

[0057] S140. The dryness is determined by the exhaust temperature measuring device;

[0058] For example, the system uses exhaust temperature data measured by an exhaust temperature measuring device to determine whether the clothes have reached a preset level of dryness.

[0059] S150. When the exhaust temperature measuring device indicates that the clothes are dry, the drying device is used to dry the clothes to be treated for an additional time.

[0060] For example, if the exhaust temperature data indicates a disc-like reading, then the clothes to be dried will undergo a supplementary drying operation via the drying unit. Supplementary drying is a process of adjusting the drying time according to actual needs to ensure that the clothes achieve the best drying effect.

[0061] In summary, the low-temperature drying operation proposed in this application controls the drying temperature within a relatively low range (e.g., 35-45°C), lower than the temperature of traditional high-temperature drying. This helps protect the fiber structure of soft materials such as silk, reducing damage caused by high temperatures, such as fiber embrittlement and color distortion, while maintaining the natural luster of the garments. The reverse rotation of the drum gaps effectively disperses the garments, preventing them from clumping together during drying. This not only improves the uniformity of drying but also speeds up the drying process and increases energy efficiency. Using data from the exhaust temperature measuring device to accurately determine the degree of drying avoids the inaccurate judgment problems common in traditional drying methods. Accurate judgment ensures that drying stops promptly once the garments reach the ideal dryness, preventing energy waste and garment damage caused by over-drying. When the exhaust temperature data meets the judgment conditions, dynamic time-addition drying adjusts the drying time according to the actual dryness of the garments, ensuring both drying effect and improved energy efficiency.

[0062] In some examples, the shut-off temperature of the heating device corresponding to the above-mentioned drying and the above-mentioned supplementary drying is 35 degrees Celsius to 45 degrees Celsius, and the start-stop temperature difference of the heating device is 3 degrees Celsius to 6 degrees Celsius.

[0063] For example, such as Figure 2 The diagram shown is a temperature rise curve of a washer-dryer combo according to an embodiment of this application. In the low-temperature drying stage and the supplementary drying stage for drying the shaken and loosened clothes, the shut-off temperature of the heating device is set between 35 and 45 degrees Celsius. The shut-off temperature refers to the temperature inside the drying device reaching the upper limit of this range, at which point the heating device automatically shuts off and stops heating to prevent overheating from damaging the clothes or wasting energy.

[0064] The start-stop temperature difference for the heating unit is set between 3 and 6 degrees Celsius. This start-stop temperature difference refers to the temperature drop below the minimum cut-off temperature after the heating unit automatically shuts off, at which point it will restart. This temperature difference setting helps maintain temperature stability during the drying process, ensuring clothes dry evenly throughout the drying cycle, and also avoids wear and tear on the equipment caused by frequent switching on and off.

[0065] By employing this temperature control strategy, washer-dryer combos can ensure effective drying while also considering energy efficiency and garment protection. This strategy makes the drying process more precise and energy-efficient, improving user satisfaction and the economic viability of the equipment.

[0066] In some examples, when the exhaust temperature measuring device indicates that the garment is dry, the drying device performs supplementary drying on the garment to be treated, including:

[0067] When the exhaust temperature indicated by the exhaust temperature measuring device is dry, the first dynamic time supplement is determined based on the working time of the drying device when the exhaust temperature is dry and the first time supplement coefficient corresponding to the exhaust temperature indication being dry.

[0068] The aforementioned drying device is used to perform time-added drying of the aforementioned clothing to be processed for the aforementioned first dynamic time-added time.

[0069] For example, when the exhaust temperature measured by the aforementioned exhaust temperature measuring device indicates dryness, the exhaust temperature remains constant for a certain period of time. When the exhaust temperature is stable, this usually indicates that most of the moisture in the clothing has been removed, because the evaporation of moisture requires the absorption of heat, and if no new moisture evaporates, the exhaust temperature will tend to stabilize.

[0070] When the exhaust temperature measuring device detects that the temperature remains constant for a preset period of time, it determines that "exhaust temperature indication indicates dryness," and the system records the duration of operation of the drying device in the current drying program. For different drying scenarios, materials, or drying needs, the garment processing equipment can pre-set several first time-addition coefficients (e.g., derived from experimental or empirical data). This first time-addition coefficient determines the proportion of additional time in the total drying time or its weight in relation to garment thickness / load. For thicker garments or special materials, the time-addition coefficient may be larger to prevent under-drying; for regular thin fabrics, the time-addition coefficient is relatively smaller. After determining the first dynamic time-addition period based on the working time and the time-addition coefficient, the dryer restarts its hot air heating or drum tumbling functions, continuing for the first time-addition period.

[0071] In some examples, when the exhaust temperature measuring device indicates that the garment is dry, the drying device performs supplementary drying on the garment to be treated, including:

[0072] When the exhaust temperature change rate indicated by the exhaust temperature measuring device is dry, the second dynamic time supplement is determined based on the working time of the drying device and the second time supplement coefficient corresponding to the exhaust temperature change rate indicated dry.

[0073] The aforementioned drying device is used to perform time-added drying of the aforementioned clothing to be treated using the aforementioned second dynamic time-added time.

[0074] For example, when the exhaust temperature change rate measured by the exhaust temperature measuring device indicates that the clothes are dry, the slope of the rise or fall of the exhaust temperature slows down to a certain value, which means that the drying state of the clothes is close to completion, because the higher the degree of dryness, the smaller the temperature change.

[0075] If the clothing still contains a lot of moisture, the heat is consumed by evaporation, and the exhaust temperature will accumulate and rise slowly or maintain a certain upward slope (or, in some modes, the rate of decrease will slow down). When the clothing is almost dry, the evaporation rate decreases significantly, and the rate of change of the exhaust temperature will gradually approach zero. The device can calculate the change in exhaust temperature per unit time (i.e., the slope) in real time. Once this slope is lower than or close to a certain set threshold and remains so for a certain period of time, it will trigger the "exhaust temperature change rate indication dryness judgment".

[0076] The current operating time of the drying unit represents the total operating time of this drying program from the start to the triggering of the "dry" signal. The second time compensation coefficient can be set with one or more sets of time compensation coefficients for different drying modes and different types of clothing based on historical experience or experimental test data.

[0077] It should be noted that, firstly, the exhaust temperature data is continuously monitored by the exhaust temperature measuring device of the drying unit. Once the exhaust temperature data first meets any of the drying criteria, the next step is initiated: either the exhaust temperature change rate indicates drying, or the exhaust temperature measuring device indicates drying. At this point, the drying unit determines a dynamic time supplement based on the operating time at which the drying criteria were met and the corresponding time supplement coefficient. The time supplement coefficient is preset based on drying experiments and experience and is used to calculate the additional drying time required to ensure the clothes are completely dry. Finally, the drying unit performs the time supplement drying operation on the clothes to be processed according to the determined dynamic time supplement time. This time is dynamically calculated to ensure that the clothes achieve optimal drying results without being over-dried.

[0078] The method proposed in this application can ensure the drying effect of clothes while avoiding unnecessary energy waste and potential damage to clothes, thus optimizing the performance and efficiency of the entire washing and drying process.

[0079] In some examples, when the exhaust temperature indicator is dry, the difference between the exhaust temperature value within a preset time period and the reference temperature is less than a preset difference. The reference temperature is determined based on the average of the shut-off temperature and the start-stop temperature difference of the drying device.

[0080] For example, the reference temperature is determined based on the average of the heating device's shut-off temperature and the start-stop temperature difference. Specifically, the heating device's shut-off temperature is set at a specific temperature point, such as 35 to 45 degrees Celsius, while the start-stop temperature difference is set between 3 and 6 degrees Celsius. The reference temperature is calculated as the average of these two parameters, providing a baseline temperature for the drying process to assess the drying status.

[0081] When determining the dryness of the exhaust temperature, the setting requirement is that within a preset time period, the difference between the exhaust temperature and the calculated reference temperature must be less than a preset difference. This preset difference is set based on actual drying experience and the characteristics of the clothing material, with the aim of accurately monitoring the stability of the exhaust temperature.

[0082] The preset duration refers to the length of time during which the exhaust temperature needs to remain stable. This duration is long enough to ensure that the exhaust temperature measurement results are reliable and representative, thus effectively determining whether the clothes have reached the ideal level of dryness.

[0083] During the drying process, the exhaust temperature measuring device continuously monitors the exhaust temperature and compares it with a reference temperature. When the difference in exhaust temperature remains consistently less than a preset value within a preset time period, the exhaust temperature indicator is considered dry. Once this condition is met, further dynamic time-addition drying operations can be performed based on the actual conditions during the drying process to ensure all garments reach optimal dryness.

[0084] In some examples, when the exhaust temperature change rate indicator is dry, the slope of the temperature change corresponding to the exhaust temperature is less than a preset slope.

[0085] For example, the exhaust temperature change slope refers to the rate of change of exhaust temperature over time during the drying process. This slope is obtained by calculating the change in exhaust temperature over a certain period of time and is used to assess the trend of temperature change.

[0086] When the slope of the exhaust temperature change is less than the preset slope, it indicates that the temperature change has become very slow and close to a steady state, thus it can be inferred that most of the moisture in the clothes has been removed and the drying process is nearing completion.

[0087] The preset slope is set based on the performance of the drying equipment, the type and material of the clothing, and drying experience. It defines a threshold to determine whether the drying process has reached a stage where moisture evaporation is slowed down, meaning the rate of temperature rise or fall during the drying process is sufficiently small.

[0088] During the drying process, the drying device continuously monitors the exhaust temperature and calculates its rate of change. By comparing the real-time calculated rate with the preset rate, the progress of the drying process can be determined.

[0089] If the slope of the monitored exhaust temperature change is less than the preset slope, it means that drying is nearing completion and the moisture content of the clothes has dropped to a low level. At this point, the exhaust temperature change rate indicator can determine whether to perform dynamic time-added drying to optimize the drying effect and ensure the quality of the clothes.

[0090] By introducing the slope of exhaust temperature change as a drying condition, the method provided in this application can more accurately monitor and control the drying process, preventing clothes from being over-dried or under-dried, thereby significantly improving the drying efficiency of the washer-dryer and the quality of clothing processing. This method is particularly suitable for high-end garments that are sensitive to drying conditions, such as silk, ensuring their safety and quality maintenance during the drying process.

[0091] In one feasible implementation, when determining the drying time based on the exhaust temperature indication, the first dynamic time supplement is determined by the working time of the drying device and the first time supplement coefficient corresponding to the exhaust temperature indication drying time, including:

[0092] The first dynamic time supplement is determined by multiplying the working time of the drying device when the exhaust temperature indicator indicates dryness by the first time supplement coefficient corresponding to the exhaust temperature indicator dryness.

[0093] In one feasible implementation, determining the second dynamic time supplement based on the operating time of the drying device when the exhaust temperature change rate indicates dryness and the second time supplement coefficient corresponding to the exhaust temperature change rate indication dryness includes:

[0094] The second dynamic time supplement is determined by multiplying the working time of the drying device when the exhaust temperature change rate indicator is dry by the second time supplement coefficient corresponding to the exhaust temperature change rate indicator.

[0095] For example, the working time refers to the total time elapsed from the start of drying until the drying condition is met. This time reflects the continuity of the drying unit's operation within the current drying cycle until a certain drying condition is met (such as a constant exhaust temperature drying condition or an exhaust temperature change slope drying condition).

[0096] The first and second time-addition factors are pre-set coefficients based on the performance of the drying equipment and the type of clothing, used to adjust the additional drying time required. These coefficients are derived from experience and data analysis of past drying processes, with the aim of ensuring that clothing reaches the ideal dryness under different conditions.

[0097] When determining the dynamic time allowance, the working time is multiplied by the corresponding time allowance coefficient (either the first or second time allowance coefficient), and the product is the dynamic time allowance. This time is dynamically adjusted based on the actual drying status of the clothes during the drying process to ensure that the clothes are completely dry without being over-dried.

[0098] After calculating the dynamic time allowance, the drying unit will continue the drying operation according to this time until the additional time allowance is completed. This ensures that all clothes to be treated achieve a uniform and ideal degree of dryness during the drying process.

[0099] This method provides a flexible and precise way to adjust drying time, optimizing it according to actual drying needs and the specific characteristics of the garments. This strategy not only improves drying efficiency but also protects garments from over-drying, making it particularly suitable for temperature- and time-sensitive high-end garments such as silk.

[0100] In some examples, the first time supplement factor mentioned above is 0.2 to 0.8.

[0101] For example, when the exhaust temperature data first meets the condition of constant exhaust temperature for drying, the time compensation factor is set in the range of 0.2 to 0.8. This means that once the exhaust temperature remains relatively constant within a preset time, indicating that the drying process is nearing completion, the time compensation factor is used to adjust the additional drying time within this range to ensure that the clothes are thoroughly dried without being over-dried.

[0102] In some examples, the second time supplement factor mentioned above is 0.1 to 0.6.

[0103] For example, if the exhaust temperature data first meets the condition of determining dryness based on the slope of the exhaust temperature change, the time compensation factor is set between 0.1 and 0.6. This setting is based on the slowing down of the exhaust temperature change slope. When the slope drops to a very low level, it means that the clothes are close to dry but may still require slight subsequent drying. The drying time is finely adjusted by using a lower time compensation factor.

[0104] In some examples, when the clothes to be treated are dehydrated by the continuous rotation of the rollers, the corresponding rotation speed of the rollers is 600 to 800 revolutions per minute.

[0105] For example, in a low-speed spin-drying operation, the continuous rotation of the drum corresponds to a speed set between 600 and 800 revolutions per minute. This speed range is selected to effectively remove moisture from clothing using physical force (centrifugal force) while ensuring no mechanical damage is caused to the clothing. Low-speed rotation helps protect clothing fibers, especially delicate or fragile materials such as silk.

[0106] In some examples, the above-mentioned shaking of the dehydrated clothes by the reverse rotation of the roller includes:

[0107] The aforementioned roller rotates in a first direction during the first cycle;

[0108] The aforementioned roller stops rotating during the second cycle;

[0109] The aforementioned roller rotates in the second direction during the third cycle.

[0110] For example, in the shaking operation, the drum first rotates in a first direction in the first cycle in order to disperse the clothes to be treated inside the drum and avoid tangling of clothes due to dehydration.

[0111] During the second cycle, the drum stops rotating, which helps the clothes to fall back into place inside the drum and reduces the sticking between the clothes.

[0112] During the third cycle, the drum rotates in a second direction, opposite to the first direction, further promoting the loosening and even distribution of the clothes, preparing them for low-temperature drying.

[0113] In some examples, the drying of the shaken clothing by the aforementioned drying device includes:

[0114] Start the aforementioned fan of the drying device;

[0115] After the fan has run for the fourth cycle, the heating device of the drying unit is activated to dry the shaken clothes.

[0116] For example, a low-temperature drying operation begins with starting the drying unit's fan. The operation of the fan helps to create a uniform airflow within the drying chamber, laying the foundation for the distribution of hot air.

[0117] After the fan has run for the fourth cycle, the heating device is activated. This step ensures that after the fan has evenly distributed the airflow in the drying chamber, the heating device provides gentle heat to dry the shaken clothes at a low temperature, thus protecting the clothes from high-temperature damage.

[0118] In some examples, the above method also includes:

[0119] At the end of the aforementioned time-added drying process, the heating device should be turned off first.

[0120] The aforementioned fan is kept running until the fifth cycle of the aforementioned heating device is shut down, after which it is turned off.

[0121] For example, at the end of the supplementary drying operation, the heating element of the drying unit is first turned off. This measure aims to stop the supply of heat and prevent over-drying.

[0122] Even after the heating element is turned off, the drying unit's fan must continue running until the fifth time cycle after the heating element is turned off. Continuous fan operation helps maintain airflow in the drying chamber, facilitates rapid heat dissipation from the heating element, helps clothes cool naturally, eliminates residual moisture, and ensures the texture and condition of the clothes after drying.
