Description

Technical Field

[0001] This invention relates to the field of smart home appliance technology, and in particular to a method, apparatus, drying equipment and storage medium for drying clothes. Background Technology

[0002] In the field of clothing drying, as people's living standards improve, their requirements for drying performance and garment protection are becoming increasingly stringent. Currently, most drying equipment on the market follows a single drying principle in its drying program. A common method is to use a humidity sensor to detect the moisture content of the clothes inside the drying drum to determine whether the clothes are completely dry.

[0003] However, because clothing made of different materials varies significantly in terms of moisture absorption, water content, and tolerance to dryness, relying solely on humidity data from a humidity sensor to uniformly determine the drying process can easily lead to over-drying. For example, excessive drying of natural fiber garments such as silk and wool can cause the fibers to lose their resilience, resulting in irreversible damage such as shrinkage, fading, and stiffening. Over-drying cotton garments will reduce their softness and significantly decrease wearing comfort, resulting in a poor user experience. Summary of the Invention

[0005] In a first aspect, embodiments of the present invention provide a method for drying clothes, comprising:

[0006] The material of the clothes to be dried is determined, and the maximum drying temperature is determined based on the material. During the drying process starting at the maximum drying temperature, the current drying stage is determined based on the change in the heater current within the current time period. The drying stage includes an initial drying stage, a main drying stage, and a post-drying stage. The corresponding drying strategy is determined based on the drying parameters corresponding to the current drying stage, so as to complete the drying operation of the clothes to be dried based on the drying strategy corresponding to each drying stage.

[0010] The strategy determination module is used to determine the corresponding drying strategy based on the drying parameters corresponding to the current drying stage, so as to complete the drying operation of the clothes to be dried based on the drying strategy corresponding to each drying stage.

[0029] Figure 1 This is a schematic flowchart of a clothes drying method provided in an embodiment of the present invention. This embodiment can be applied to the process of drying clothes through a clothes drying device to avoid damage to the clothes due to over-drying. The method can be executed by a clothes drying device, which can be implemented in hardware and / or software and can be configured in a clothes drying device.

[0030] refer to Figure 1 The specific steps of this clothes drying method may include:

[0031] S110. Determine the material of the clothes to be dried, and determine the maximum drying temperature based on the material.

[0032] Clothes to be dried refer to all kinds of clothing that need to have their moisture removed by a drying device to achieve a dry state. This includes, but is not limited to, everyday clothing such as shirts, pants, and skirts, as well as bedding, towels, and other textiles. The drying device described in this embodiment is a device with a drying function, such as a washer-dryer combo or a dedicated dryer.

[0033] Clothing material refers to the type of raw materials used to make up clothing. Common types include natural fibers such as cotton, linen, silk, and wool; chemical fibers such as polyester, nylon, and acrylic; and blends of natural and synthetic fibers. Because different clothing materials have different physical and chemical properties, they vary in their temperature tolerance during the drying process.

[0034] Specifically, how can the material of the clothes to be dried be determined?

[0035] Method 1: Before starting the drying program, users can manually select the material type of the clothes to be dried via the touch screen or buttons on the dryer, or through a mobile terminal connected to the dryer. For example, the interface may display common material options such as "cotton," "wool," "silk," and "polyester," which users can select according to the material of the clothes to be dried. Additionally, for some special or mixed materials, an "Other" option can be provided with an input box for users to describe the material information.

[0036] Method 2: A high-definition camera is built into the dryer. After the user places the clothes into the drying drum, the device automatically takes a picture of the clothes. Using image recognition algorithms, the device analyzes the texture, color, weave pattern, and other features of the clothes to determine their material composition.

[0037] Method 3: Install material sensors inside the drying drum or at the equipment inlet. When clothes pass through the sensor area, the sensors can determine the material by detecting the chemical composition and physical properties (such as conductivity and hygroscopicity) of the clothes. For example, wool is rich in protein, and its chemical properties differ from other materials. The sensor can identify wool based on the specific chemical signals detected. Similarly, different fiber materials have different electrical conductivity, and the material of the clothes can be determined by detecting their conductivity. The specific method for determining the material of the clothes to be dried is not limited here.

[0038] The maximum drying temperature is the highest temperature that the garment can withstand during drying without damaging the material, affecting its lifespan, or its appearance. Exceeding this temperature may cause shrinkage, fading, deformation, or fiber damage.

[0039] In this embodiment, the method for determining the maximum drying temperature based on the clothing material can be as follows: A comprehensive and accurate database is pre-established in the control system of the drying equipment. This database records in detail the maximum drying temperatures for various common clothing materials. For example: For cotton clothing, the maximum drying temperature is typically set between 65℃ and 75℃, because cotton fibers have good heat resistance, allowing for efficient drying within this temperature range while ensuring the clothing remains undamaged; for wool clothing, the maximum drying temperature is generally controlled between 45℃ and 55℃, as wool fibers are more sensitive to temperature, and excessively high temperatures can easily lead to shrinkage and fiber damage; for silk clothing, the maximum drying temperature is often set between 40℃ and 50℃, requiring relatively low temperatures to protect its soft, smooth texture and vibrant colors; for clothing made of synthetic fibers such as polyester, the maximum drying temperature can be set between 60℃ and 70℃, as synthetic fibers are relatively stable.

[0040] Specifically, after determining the material of the clothes to be dried, the control system will look up the corresponding maximum drying temperature in a pre-established material temperature mapping table. Then, it will automatically set this temperature as the upper limit of the drying program, ensuring that the temperature inside the drying drum does not exceed the maximum limit that the material can withstand during the entire drying process, thereby effectively protecting the clothes from damage during drying.

[0041] S120. During the drying process that starts based on the highest drying temperature, the current drying stage is determined based on the change in the heater current within the current time period.

[0042] Since the moisture content of the clothes to be dried is relatively high at the start of the drying process, the drying operation is performed at the highest drying temperature in the initial stage to ensure drying efficiency. Because drying clothes is a relatively long process, such as 1 hour, 2 hours, or 3 hours, continuously drying at the highest temperature could damage the clothes due to their low moisture content. Therefore, the solution provided in this embodiment acquires the heating current of the heater at regular intervals and determines the current drying stage based on the change in current. In this embodiment, the drying process includes an initial drying stage, a main drying stage, and a post-drying stage. Although broadly divided into three drying stages, this embodiment formulates corresponding drying strategies based on the drying parameters obtained within the current time period in each drying stage. These strategies aim to protect the clothes in each drying stage and improve drying efficiency.

[0043] The heater is a device in a clothes drying machine used to generate heat and provide a heat source for the drying process. It converts electrical energy into heat energy by passing an electric current through heating elements such as resistance wires, thereby raising the temperature inside the drying drum and accelerating the evaporation of moisture from the clothes. Furthermore, during the drying process, the heater's operating state changes at different stages due to factors such as the moisture content of the clothes and heating requirements, causing fluctuations in the current flowing through the heater. The change in current refers to the difference between the real-time measured value of the heater current in the current time period and the measured value in the previous time period. This difference can be positive or negative, reflecting the dynamic changes in the current.

[0044] The initial drying stage marks the beginning of the drying process. Its main purpose is to rapidly raise the temperature inside the drying drum, causing the surface moisture of the clothing to begin evaporating. During this stage, the heater typically operates at high power, with a large and relatively variable current. The main drying stage follows the initial drying stage and is the primary stage where a large amount of moisture evaporates from the clothing. At this point, the temperature inside the drying drum stabilizes within the suitable drying temperature range for the fabric, the heater power remains relatively stable, and the current is also relatively steady, ensuring continuous and efficient removal of moisture from the clothing. The final drying stage is the final stage of the drying process. At this point, the moisture content of the clothing is already low, and the main task is to further remove residual moisture and perform appropriate shaping treatments to achieve the desired drying and shaping effect. In this stage, the heater power gradually decreases, and the current also decreases and tends to stabilize.

[0045] S130. Determine the corresponding drying strategy based on the drying parameters corresponding to the current drying stage, and complete the drying operation of the clothes to be dried based on the drying strategy corresponding to each drying stage.

[0046] The drying parameters corresponding to the current drying stage represent a series of adjustable or monitorable values ​​closely related to the drying process, including but not limited to drying temperature (actual operating temperature and maximum allowable temperature), heating power, fan speed, and drying time. This embodiment controls these parameters to change according to drying requirements at different drying stages to achieve the best drying effect.

[0047] A drying strategy is a plan for adjusting drying parameters at different drying stages. Specific measures include controlling and adjusting heating power, adjusting fan speed, and setting drying time to ensure efficient and energy-saving drying operations at each stage while protecting clothing.

[0048] Specifically, after determining the fabric material and the maximum drying temperature, the drying equipment collects relevant parameters in real time at each drying stage. For example, in the initial drying stage, it collects real-time data such as heater power, current (reflecting heating power), real-time temperature rise rate inside the drying drum, and fan speed. In the main drying stage, it focuses on collecting data such as stable drying temperature, current heating power, fan speed, and outlet humidity. In the later drying stage, it monitors temperature adjustments, gradually decreasing heating power, changes in garment weight (indirectly reflecting moisture content), and fan speed adjustments. The control system analyzes the collected parameters, comparing the actual parameters with preset standard parameter ranges for the fabric material and drying stage. For example, for cotton garments in the main drying stage, the standard drying temperature range might be 60℃-65℃. If the actual temperature is lower than this range, the control system determines that the heating power needs to be appropriately increased.

[0049] Furthermore, during the operation of the drying equipment, the drying parameters corresponding to each drying stage are continuously monitored, and the drying strategy is dynamically adjusted according to the actual situation. If the actual temperature exceeds the maximum drying temperature, the heating power is immediately reduced; if the outlet humidity is abnormal, the fan speed is adjusted in a timely manner; the drying equipment controls each component to perform corresponding operations according to the pre-defined drying strategy. The heater heats according to the set power, and the fan operates at the adjusted speed. The equipment monitors various parameters in the drying process in real time through sensors and feeds the data back to the control system. The control system judges the execution effect of the drying strategy based on the feedback data. If deviations occur, adjustments are made again to ensure that the entire drying process proceeds smoothly according to the drying strategy corresponding to the current stage, until the drying operation of the clothes is completed.

[0050] This embodiment, by developing personalized drying strategies for different drying stages, ensures that garments receive the most suitable treatment at each stage, comprehensively improving drying results and maintaining the garments' good texture and shape. By combining the maximum drying temperature with strict control of temperature and other parameters at each drying stage, damage to the garment materials caused by excessive heat or improper drying methods is avoided. For fragile materials such as silk and wool, precise strategy control effectively reduces problems such as shrinkage, fading, and deformation, extending the garment's lifespan.

[0051] The clothing drying method provided in this invention first determines the maximum drying temperature based on the material of the clothing to be dried, allowing for personalized settings of the maximum drying temperature for different materials, thus protecting the clothing. Secondly, during the drying process, the current drying stage is determined based on the change in heater current, providing real-time and accurate information about the actual drying status of the clothing and laying the foundation for subsequent drying strategies based on the drying stage. Finally, a personalized drying strategy is formulated based on the drying parameters generated by the clothing at different drying stages, ensuring that the clothing receives optimal treatment at each stage and preventing over-drying. This solution achieves the beneficial effects of improving drying efficiency and enhancing user experience.

[0052] Figure 2 This is another schematic flowchart of the clothing drying method provided in this embodiment of the invention. The relationship between this embodiment and the above embodiments is a further refinement of the corresponding features of the above embodiments. Specifically, it refines the specific implementation of "determining the maximum drying temperature according to the clothing material", the specific implementation of "determining the current drying stage according to the change in heater current", and the specific implementation of "determining the corresponding drying strategy according to the drying parameters corresponding to the current drying stage", etc.

[0053] like Figure 2 As shown, the clothes drying method provided in this embodiment may include the following steps:

[0054] S210. Determine the material of the clothes to be dried.

[0055] S211. Obtain the material temperature mapping table.

[0056] A material temperature mapping table is a dataset compiled from experimental tests, collecting performance data on various common clothing materials at different temperatures, such as changes in fiber strength, color stability, and dimensional changes. Based on this data, the highest drying temperature that each material can withstand without affecting its physical and chemical properties is determined. In the material temperature mapping table, each clothing material corresponds to a specific drying temperature.

[0057] For example, the mapping relationships in the specific material temperature mapping table may include: cotton -70℃, wool -55℃, silk -50℃, polyester fiber -65℃, and linen -68℃, etc. This mapping table is stored in the storage unit inside the control system of the drying equipment so that the equipment can call it at any time.

[0058] S212. Obtain the material type corresponding to the clothing material, and determine whether the material type includes one.

[0059] In this embodiment, the methods for obtaining clothing material include, but are not limited to, user input, image recognition based on video shooting technology, and sensor detection. The specific methods for obtaining clothing material will not be described in detail here.

[0060] Specifically, after obtaining the material of the garment, it is then determined whether the material type includes one type. The purpose of this is to prevent damage to the garments caused by inaccurate determination of the maximum drying temperature when multiple types of materials are mixed and dried.

[0061] Specifically, if the material type includes one, then execute S213; if the material type does not include one, then execute S214.

[0062] S213. Determine the maximum drying temperature from the material temperature mapping table based on the fabric of the garment.

[0063] When the equipment determines that the clothing material is of only one type, the control system directly looks up the maximum drying temperature corresponding to that material in the material temperature mapping table. For example, if the clothing material is determined to be "wool," the control system reads from the mapping table that the maximum drying temperature corresponding to wool is 55℃, and sets this temperature as the maximum temperature limit for this drying operation.

[0064] S214. Obtain the drying temperatures corresponding to various clothing materials from the material temperature mapping table, and determine the temperature with the lowest value among the multiple drying temperatures as the highest drying temperature.

[0065] If the system detects that the garment contains multiple materials, it searches the material temperature mapping table for the maximum drying temperature corresponding to each material. For example, for a garment made of a blend of cotton and polyester, the maximum drying temperature for cotton is found to be 70℃, and for polyester, it is 65℃. The system then compares these temperature values ​​and selects the lowest value, 65℃, as the maximum drying temperature for this blended garment. This ensures that none of the materials are damaged by excessive heat during the drying process.

[0066] The method for determining the maximum temperature for clothing materials provided in this embodiment precisely controls the upper limit of temperature during the drying process by accurately determining the maximum drying temperature for each material and mixed-material garments. This avoids problems such as fiber damage, shrinkage, and fading caused by excessively high temperatures. For mixed-material garments, using the lowest suitable temperature as the maximum drying temperature ensures that different material parts can complete the drying process evenly within a safe temperature range. This avoids overheating of some materials due to their high temperature tolerance, which could damage other materials, while ensuring that all materials are fully dried, thus improving the uniformity of the overall drying effect.

[0067] S220. During the drying process that starts according to the highest drying temperature, the change in current during the first time period is obtained within the current time period.

[0068] A high-precision current sensor is integrated into the heater circuit of the drying equipment. This sensor monitors the current flowing through the heater in real time and converts the analog current signal into a digital signal, which is then transmitted to the control system of the drying equipment at a fixed sampling frequency (e.g., once every 10 seconds). The control system continuously records this current data, forming a time-series current value data set.

[0069] Within the current time period after the drying cycle starts, the control system calculates the current change within a first time period (e.g., 1 minute). The current change is calculated as the difference between the current value at the current moment and the current value at the previous moment within the current time period. If the load of clothes continues to decrease and the water volume decreases, the current change within the first time period will be negative; otherwise, it will be positive. Optionally, the aforementioned first time period can also be 30 seconds or 2 minutes, etc., and the specific setting of the first time period is not limited here.

[0070] S221. Determine whether the change in current exceeds the first threshold.

[0071] If the change in current does not exceed the first threshold (i.e., no), then execute S222; if the change in current exceeds the first threshold (i.e., yes), then execute S223.

[0072] The first threshold can be a pre-set fixed value or a preset multiple of the highest current value within the first time period, such as 0.1 times or 0.2 times. For example, taking a first time period of 20 seconds, if the current value obtained at the initial moment is 8 amps and the current value obtained after 20 seconds is 5 amps, the current change indicates a decrease of 3 amps within 20 seconds. This means that if the heating element current is detected to decrease by more than 20% continuously within the first time period, the current change exceeds the first threshold. The specific definition of the first threshold is not limited here.

[0073] S222. Determine the current drying stage as the initial drying stage;

[0074] During the initial drying stage, the heater typically operates at higher power and the current is relatively large. However, as the equipment strives to reach the preset stable temperature, the current fluctuation is relatively small, so the current change does not exceed the first threshold.

[0075] S223. Obtain the rate of change of clothing weight in the second time period and determine whether the rate of change of clothing weight exceeds the second threshold.

[0076] The drying equipment is equipped with a high-precision weight sensor, which is mounted on the support structure of the drying drum and can measure the total weight of the drum and the clothes inside in real time. When the current change exceeds a first threshold, the control system initiates focused monitoring of the clothing weight data. Weight data is collected at fixed time intervals (e.g., once per minute), and the rate of change in clothing weight is calculated based on the weight data from adjacent time points. The formula for calculating the rate of change in clothing weight is:

[0077] (Previous weight - Current weight) / Previous weight × 100%

[0078] If the rate of change of clothing weight exceeds the second threshold, then proceed to step S224; if the rate of change of clothing weight does not exceed the second threshold, then proceed to step S225.

[0079] The second time period can be 30 seconds, 60 seconds, or 90 seconds, etc., and there are no restrictions on the specific selection of the second time period.

[0080] The second threshold is used to represent the change in the moisture content of the clothing during the second time interval. As the drying time increases, the moisture content of the clothing gradually decreases. The second threshold can be 5%, 10%, or 15%, etc., and the specific determination of the second threshold is not limited here. Furthermore, the rate of change in clothing weight within the same time interval will also differ depending on the clothing material. Therefore, the second threshold provided in this embodiment can also be dynamically set according to different clothing materials.

[0081] S224. Determine the current drying stage as the main drying stage.

[0082] After the current change exceeds the first threshold, the control system acquires the weight change rate of the clothing within a second time period. If the weight change rate of the clothing within this time period exceeds the second threshold, it indicates that the moisture in the clothing is evaporating rapidly, and the control system determines that the current drying stage is the main drying stage. During the main drying stage, due to the high moisture content of the clothing, a large amount of moisture evaporates, causing the weight to drop rapidly, thus the weight change rate exceeds the second threshold.

[0083] S225. Determine the current drying stage as the post-drying stage.

[0084] If the rate of change in clothing weight does not exceed the second threshold during the second time period, it indicates that most of the moisture in the clothing has been removed, and the current drying stage enters the post-drying stage. In this stage, the main focus is on removing residual moisture from the clothing and performing appropriate shaping treatments. The weight change of the clothing tends to be gradual, resulting in a lower rate of weight change.

[0085] The method for determining the current drying stage provided in this embodiment uses a combination of current change and garment weight change rate to judge the drying stage, enabling a more accurate grasp of the actual state of the garments during the drying process. Compared to traditional methods that rely solely on time settings or a single temperature sensor to divide the drying stage, this solution can dynamically adjust the drying strategy in real time according to the drying status of the garments, ensuring that each stage receives the most suitable treatment, thus improving the accuracy and controllability of the drying process.

[0086] S230. Determine the corresponding drying strategy based on the drying parameters corresponding to the current drying stage, and complete the drying operation of the clothes to be dried based on the drying strategy corresponding to each drying stage.

[0087] In a preferred implementation, the clothes drying solution provided in this embodiment, when the current drying stage is the initial drying stage, and the drying parameters corresponding to the initial stage include at least the first power parameter and the first air volume parameter, the above step S230 can be achieved by the following steps a) to c):

[0088] a) Determine the first initial power parameter and the first initial air volume parameter of the heater based on the highest drying temperature.

[0089] First, through extensive drying experiments on different clothing materials, the power required by the heater and the airflow output by the fan were recorded to achieve the optimal initial drying effect for each material. Based on this, a mapping table was established between the maximum drying temperature corresponding to each material and the first initial power parameter and the first initial airflow parameter. For example, for cotton clothing, the experiments showed that at a maximum drying temperature of 70℃, the suitable first initial power parameter for the heater in the initial stage was 80% of the rated power, and the first initial airflow parameter for the fan was 70% of the maximum airflow; for wool clothing, at a maximum drying temperature of 55℃, the first initial power parameter was 60% of the rated power, and the first initial airflow parameter was 50% of the maximum airflow, and so on.

[0090] b) Obtain the weight of the clothing at every third time interval, determine the current first air volume parameter based on the weight of the clothing, and determine the current first power parameter based on the current first air volume parameter.

[0091] During the initial drying phase, the drying equipment is equipped with a high-precision weight sensor that measures the total weight of the drying drum and the clothes inside at fixed time intervals (i.e., the third time period, for example, every 5 minutes), and transmits the weight data to the control system. The control system determines the current initial airflow parameter based on the real-time weight data and a pre-set weight-airflow correlation rule. For example, the rule might be that when the weight of the clothes is between 80% and 100% of the initial weight, the airflow remains at the initial parameter; when the weight drops to 60%-80% of the initial weight, the airflow is adjusted to 60% of the maximum airflow; and when the weight is below 60% of the initial weight, the airflow further decreases to 50% of the maximum airflow. Assuming the initial weight of the clothes is 10 kg, and after 5 minutes the weight is measured at 8.5 kg, according to the rule, the current initial airflow parameter remains at 70% of the initially set maximum airflow.

[0092] After determining the current primary airflow parameter, the control system determines the current primary power parameter based on the correlation between airflow and power. Generally, there is a positive correlation between airflow and power; that is, when the airflow increases, the power also needs to be appropriately increased to ensure the drying effect. For example, when the airflow is 70% of the maximum airflow, the power is maintained at 80% of the rated power; when the airflow drops to 60% of the maximum airflow, the power is adjusted accordingly to 70% of the rated power. Therefore, in the above example, when the current primary airflow parameter is maintained at 70% of the maximum airflow, the current primary power parameter is also maintained at 80% of the rated power.

[0093] c) Perform drying operation on the clothes to be dried in the initial drying stage according to the current first air volume parameter and the current first power parameter.

[0094] The control system of the drying equipment controls the fan and heater to perform corresponding operations based on the determined current first air volume parameter and current first power parameter. The fan adjusts its speed according to the current first air volume parameter to output a suitable air volume, accelerate the airflow inside the drying drum, and remove the moisture evaporated from the clothes; the heater adjusts its heating power according to the current first power parameter to provide suitable heat for the drying process. Throughout the initial drying stage, the equipment continues to operate in this way of real-time parameter adjustment until the conditions for entering the main drying stage are met.

[0095] This embodiment provides a method for determining the appropriate drying strategy based on corresponding drying parameters during the initial drying stage. By determining the initial power and airflow parameters according to the fabric material and the maximum drying temperature, the drying equipment can operate in a suitable state from the beginning, quickly raising the temperature inside the drying drum and laying the foundation for efficient moisture evaporation. Simultaneously, real-time monitoring of the garment weight and dynamic adjustment of power and airflow parameters during the drying process allows for timely optimization of drying conditions based on the actual dryness of the garments. Furthermore, for garments of different materials, appropriate initial power and airflow settings can prevent damage caused by overheating or excessive airflow.

[0096] In another preferred implementation, the clothes drying solution provided in this embodiment, when the current drying stage is the main drying stage, includes a constant-speed drying sub-stage, and the drying parameters corresponding to the constant-speed drying sub-stage include at least a second power parameter or a third power parameter; the above step S230 can be achieved through the following steps d) to f):

[0097] d) During the constant-rate drying sub-stage, the current cylinder temperature and initial second heating power are obtained every fourth time interval.

[0098] After the dryer starts and enters the constant-speed drying sub-stage of the main drying phase, the control system first records the initial second heating power. This power value is determined by a pre-set algorithm based on the fabric material, the maximum drying temperature, and the operating conditions of the previous drying stages. For example, for cotton clothing, the initial second heating power might be set to 70% of the rated power at the start of the main drying stage. Simultaneously, a first and second temperature value are set for temperature comparison. These two temperature values ​​are also determined based on extensive experiments and experience and are related to the fabric material and the maximum drying temperature. For example, for cotton clothing with a maximum drying temperature of 70℃, the first temperature might be set to 65℃ and the second temperature to 68℃.

[0099] e) When the current temperature inside the cylinder is not higher than the first temperature, control the initial second power parameter to increase, obtain the current second power parameter, and the current second power parameter is not higher than the first power value; or, when the current temperature inside the cylinder is higher than the second temperature, control the initial second heating power to decrease, obtain the current third power parameter, and the current third power parameter is not higher than the second power value.

[0100] When the control system receives the current drum temperature data, it compares it with a first temperature. If the current drum temperature is not higher than the first temperature, it indicates insufficient heat in the drying drum, requiring an increase in heating power to maintain constant-speed drying efficiency. The control system increases the initial second power parameter according to a preset power increase rule. For example, each increase is 5% of the rated power until the current second power parameter is obtained. However, during the increase, the current second power parameter is monitored in real time to ensure that it does not exceed the preset first power value. Assuming the initial second heating power is 70% of the rated power and the first power value is 85% of the rated power, when the current drum temperature is 63℃ (not higher than the first temperature of 65℃), the control system increases the power to 75% (rated power) and uses this as the current second power parameter.

[0101] If the current drum temperature is higher than the second temperature, it indicates that the heat inside the drying drum is too high, which may damage the clothing material or lead to energy waste. In this case, the heating power needs to be reduced. The control system controls the initial reduction of the second heating power according to the preset power reduction rules to obtain the current third power parameter. Similarly, during the reduction process, it ensures that the current third power parameter does not exceed the second power value. For example, the power reduction is 3% of the rated power each time, and the second power value is set to 60% of the rated power. If the current drum temperature is 70℃ (higher than the second temperature of 68℃), and the initial second heating power is 75% of the rated power, the control system will reduce the power to 72% (rated power) as the current third power parameter.

[0102] f) The clothes to be dried are dried in the constant speed drying sub-stage according to the current second power parameter or the current third power parameter.

[0103] The control system of the drying equipment controls the heater to perform corresponding heating operations based on the determined current second or third power parameter. When the current second power parameter is determined, the heater heats at that power value, increasing the temperature inside the drying drum and accelerating the evaporation of moisture from the clothes. When the current third power parameter is determined, the heater operates at a lower power to reduce the temperature inside the drying drum and prevent excessive heat from adversely affecting the clothes. Throughout the constant-speed drying sub-stage, the equipment continuously operates according to this temperature monitoring and power adjustment method to ensure the stability and efficiency of the drying process.

[0104] The solution provided in this embodiment divides the main drying stage into a constant-speed drying sub-stage and a decreasing-speed drying sub-stage. In the constant-speed drying sub-stage, the drying strategy formulated according to the drying parameters can maintain a suitable temperature environment inside the drying drum at all times, ensuring that the clothes evaporate moisture at a stable rate during the constant-speed drying sub-stage.

[0105] In another preferred embodiment, the main drying stage provided in this embodiment further includes a falling-rate drying sub-stage; the execution priority of the constant-rate drying sub-stage is higher than that of the falling-rate drying sub-stage; the drying parameters corresponding to the falling-rate drying sub-stage include at least the outlet humidity parameter and the fourth power parameter; then, after the constant-rate drying sub-stage, the above step S230 can be achieved through the following steps g) to j):

[0106] g) When the outlet humidity parameter is detected to be no higher than the preset humidity value, the current drying stage is determined to be a falling-rate drying sub-stage.

[0107] A high-precision humidity sensor is installed at the outlet of the drying drum in the drying equipment to monitor the humidity of the exhaust gas in real time, i.e., the outlet humidity parameter. During the main drying stage, the control system continuously receives the outlet humidity parameter from the humidity sensor and compares it with a preset humidity value. The preset humidity value is determined through extensive experiments and research on the drying characteristics of different fabrics; for example, for cotton clothing, the preset humidity value might be set to 40% RH (relative humidity). When the control system detects that the outlet humidity parameter is not higher than the preset humidity value, it determines that the current drying stage has entered a slow-down drying sub-stage. This is because when the outlet humidity decreases to a certain level, it indicates that most of the moisture in the clothing has been evaporated, and the slow-down drying stage is entered to remove residual moisture in a gentler way.

[0108] h) During the slow-drying sub-stage, the initial fourth power parameter is obtained.

[0109] Once the system determines that it has entered the slow-drying sub-stage, the control system retrieves the initial fourth power parameter from a pre-set parameter database. This parameter can also be determined based on the fabric type, the maximum drying temperature, and the operating conditions of the previous drying stages. For example, for cotton garments with a maximum drying temperature of 70°C, the initial fourth power parameter might be set to 50% of the rated power at the start of the slow-drying sub-stage.

[0110] i) Every fifth time interval, the initial fourth power parameter is reduced by a preset step size to obtain the current fourth power parameter.

[0111] The control system initiates a power adjustment process at fixed time intervals (i.e., the fifth time period, for example, every 10 minutes). During each adjustment, the control system reduces the initial fourth power parameter by a preset step size to obtain the current fourth power parameter. The preset step size is also determined based on experiments and experience; for example, for cotton clothing, the preset step size might be set to 3% of the rated power. Assuming the initial fourth power parameter is 50% of the rated power, after the first fifth time period, the power decreases to 47% (rated power), and this is taken as the current fourth power parameter.

[0112] j) Based on the current fourth power parameters, the clothes to be dried are dried in the slow-down drying sub-stage.

[0113] The control system of the drying equipment controls the heater to perform corresponding heating operations based on the determined current fourth power parameter. As time progresses, the heater power gradually decreases, causing the temperature inside the drying drum to slowly drop as well. During this process, a certain temperature and airflow are maintained inside the drying drum to continue removing residual moisture from the clothes. Simultaneously, the gradual decrease in power and temperature prevents damage to the clothes caused by overheating, ensuring that the clothes receive proper treatment during the slow-drying sub-stage. Throughout the slow-drying sub-stage, the equipment continues to operate in this manner, monitoring humidity and adjusting power, until the drying operation is complete.

[0114] It should be noted that the selection of the first time period, the second time period, the third time period, the fourth time period, and the fifth time period mentioned in the embodiments of this application may be the same or different. The specific selection of values ​​within each time period shall be based on the actual needs of the developers and is not limited here.

[0115] The solution provided in this embodiment determines the drying strategy based on the drying parameters of the constant-rate drying stage. By monitoring the outlet humidity parameter, it accurately determines the timing for entering the falling-rate drying stage, enabling a gentler drying method to be used after most of the moisture in the clothes has evaporated. As the power gradually decreases, the temperature slowly drops, ensuring that residual moisture is evenly removed from the clothes. This avoids situations where clothes are over-dried or unevenly dried due to excessively high temperatures or drying speeds, further improving the drying effect and achieving the ideal dryness of the clothes.

[0116] In another preferred embodiment, when the current drying stage is the post-drying stage, and the drying parameters corresponding to the post-drying stage include at least the target temperature parameter and the second air volume parameter, the above step S230 can be achieved through the following steps k) to o):

[0117] k) Determine the temperature difference based on the current temperature inside the drying drum and the target temperature.

[0118] The current temperature is the temperature inside the drying drum when it enters the post-drying stage. The target temperature is the temperature before the drying program stops running. The current target temperature should be a comfortable temperature for the user to remove the clothes after drying is complete.

[0119] The temperature difference is calculated as follows: if the current temperature is 55℃ and the target temperature is 45℃, then the temperature difference is 10℃.

[0120] l) Determine the amount of heat to be released based on the temperature difference and the current weight of the clothing.

[0121] Based on the temperature difference and the current weight of the clothing, the heat to be released is determined using a pre-established heat calculation formula. This formula takes into account factors such as the specific heat capacity of the clothing material (different materials have different specific heat capacities, such as cotton clothing having a relatively large specific heat capacity), the weight of the clothing, and the required temperature reduction. For example, for 1 kg of cotton clothing with a specific heat capacity of c and a temperature difference of 10℃, the heat to be released is Q = mcΔT (where m is the weight of the clothing and ΔT is the temperature difference).

[0122] m) Determine the second air volume parameter based on the heat to be released.

[0123] The control system determines the required secondary airflow parameter based on the amount of heat to be released and the heat exchange characteristics of the fan. For example, if the amount of heat to be released is large, a higher airflow is required to quickly reduce the temperature to the target value. The control system calculates the corresponding secondary airflow parameter, such as 50% of the fan's maximum airflow.

[0124] n) If the second air volume parameter is higher than the preset air volume parameter, the clothes to be dried will be dried in the post-drying stage based on the second air volume parameter until the temperature inside the drying drum reaches the target temperature.

[0125] The calculated second airflow parameter is compared with the preset airflow parameter. If the second airflow parameter is higher than the preset airflow parameter, the control system controls the fan to operate at the wind speed corresponding to the second airflow parameter, accelerating the circulation of air inside the drying drum, quickly removing heat, and lowering the temperature inside the drying drum. During operation, the temperature sensor continuously monitors the temperature until the temperature inside the drying drum reaches the target temperature. For example, if the second airflow parameter is 50% of the fan's maximum airflow, which is higher than the preset 40%, the fan will operate at 50% of its maximum airflow speed to accelerate cooling.

[0126] o) If the second air volume parameter is not higher than the preset air volume parameter, then the clothes to be dried will be dried in the post-drying stage based on the preset air volume parameter until the temperature inside the drying drum reaches the target temperature.

[0127] If the second airflow parameter is not higher than the preset airflow parameter, to avoid insufficient airflow affecting the drying effect or excessive airflow damaging the clothes, the control system controls the fan to operate at the wind speed corresponding to the preset airflow parameter. Similarly, during operation, the temperature sensor monitors the temperature in real time until the temperature inside the drying drum reaches the target temperature. For example, if the calculated second airflow parameter is 35% of the fan's maximum airflow, which is lower than the preset 40%, the fan will operate at 40% of its maximum airflow speed for stable heat exchange and temperature regulation.

[0128] This embodiment provides a solution for determining the drying strategy based on drying parameters in the post-drying stage. By monitoring the temperature inside the drying drum in real time and accurately calculating the heat to be released based on the temperature difference and the weight of the clothes, appropriate airflow parameters are determined to control the rate of temperature drop, precisely adjusting the temperature inside the drying drum to the target temperature. This precise temperature control ensures that residual moisture is effectively removed from the clothes in the post-drying stage while avoiding adverse effects on the clothes due to excessively high or low temperatures, thus improving the stability and consistency of the drying effect.

[0129] The clothing drying method provided in this invention first determines the maximum drying temperature based on the material of the clothing to be dried, allowing for personalized settings of the maximum drying temperature for different materials, thus protecting the clothing. Secondly, during the drying process, the current drying stage is determined based on the change in heater current, providing real-time and accurate information about the actual drying status of the clothing and laying the foundation for subsequent drying strategies based on the drying stage. Finally, a personalized drying strategy is formulated based on the drying parameters generated by the clothing at different drying stages, ensuring that the clothing receives optimal treatment at each stage and preventing over-drying. This solution achieves the beneficial effects of improving drying efficiency and enhancing user experience.
