Abstract

This invention provides a method for controlling the shaking and scattering of clothing and a clothing processing device, applicable to a clothing processing device with a drying function. The clothing processing device includes an inner drum. An infrared temperature sensor detects the temperature inside the inner drum to obtain temperature matrix data at the current moment. Areas in the temperature matrix data with temperatures lower than a preset temperature are marked as undried clothing areas at this time. The trend of change in the undried clothing areas is determined, and the clothing processing device is controlled to shake and scatter the clothing based on this trend. This invention utilizes the trend of change in the undried clothing areas to control the clothing processing device to shake and scatter the clothing, rather than controlling it according to a fixed cycle. This timely solution addresses the tangling problem that occurs during the drying process, allowing the undried areas to be exposed promptly and improving the drying effect.

Description

Technical Field

[0001] This invention relates to the field of home appliance control technology, and in particular to a method for controlling the shaking and scattering of clothing and a clothing processing device. Background Technology

[0002] During the drying process in a tumble dryer, clothes are prone to tangling, which affects drying efficiency. Traditional tumble dryers typically use periodic forward and reverse rotation to shake the clothes and prevent tangling. However, because the rotation cycle is fixed, tangling cannot be resolved until the next cycle, meaning the problem is often not addressed immediately. Continued tangling not only affects the evenness of drying but can also cause wear and tear and distortion of the clothes. Summary of the Invention

[0003] This invention provides a method for controlling the shaking of clothes and a clothing processing device, which can promptly solve the problem of tangling that occurs during the drying process of clothes and improve the drying effect.

[0004] In a first aspect, the clothing shaking control method provided in the embodiments of the present invention is applied to a clothing processing device having a drying function and including an inner drum, and the specific method includes:

[0005] Infrared temperature sensors are used to detect the temperature inside the inner cylinder, obtaining the current temperature data.

[0006] The areas corresponding to points in the temperature matrix data where the temperature is lower than the preset temperature are marked as the areas of undried clothes at this time.

[0007] Determine the trend of changes in the undried clothing area, and control the clothing processing equipment to shake and loosen the clothing based on the corresponding trend.

[0008] Optionally, the trend of changes in the undried clothing area can be used to determine whether clothing tangling has occurred. If clothing tangling has occurred, the clothing handling equipment can be controlled to shake the clothing apart.

[0009] Optionally, the inner drum can be rotated in the opposite direction to the current direction to shake and loosen the clothes.

[0010] Optionally, the trend of changes in the undried clothing area may include changes in the size of the area.

[0011] Optionally, the following process may be included:

[0012] Calculate the area of ​​undried clothes at the current moment and compare it with the area of ​​the largest undried clothes area in this cycle. If the deviation value is greater than the set area threshold, control the clothes processing equipment to shake and disperse the clothes.

[0013] Optionally, the area of ​​the undried clothing area at the current moment can be represented by the number of low-temperature points in the temperature matrix data at the current moment.

[0014] Optionally, the trend of changes in the undried clothing area includes changes in the proportion of the undried clothing area in the overall testing area.

[0015] Optionally, the following process may be included:

[0016] Calculate the proportion of undried clothing in the overall detection area at the current moment, obtain the proportion of undried clothing area, and compare it with the largest proportion of undried clothing area in this cycle. If the decrease exceeds the set threshold, control the clothing processing equipment to shake and disperse the clothing.

[0017] Optionally, when calculating the proportion of undried clothing areas, the proportion of low-temperature points in the temperature matrix data at the current moment can be used.

[0018] Secondly, the clothing processing equipment provided in the embodiments of the present invention adopts the clothing shaking control method of any embodiment of the present invention.

[0019] In this embodiment of the invention, an infrared temperature sensor can be used to acquire real-time temperature matrix data inside the inner drum. The area of ​​undried clothing is then marked based on this data, and the tangling of clothing is dynamically identified based on the changing trend of this undried area. Infrared non-contact detection ensures the reliability of the detection system. Instead of a fixed cycle, the clothing handling equipment is directly controlled to shake and disperse the clothing based on the changing trend of the undried area. This real-time response mechanism quickly resolves the tangling problem. Timely and precise shaking exposes the undried areas, improving drying uniformity and effectively shortening drying time, thus increasing overall drying efficiency. Intelligent detection and control maintain uniform heating and drying of clothing, preventing uneven drying caused by prolonged accumulation in one area. Furthermore, timely shaking reduces excessive friction caused by tangling, significantly reducing the risk of wear and tear and preserving the original shape and texture of the clothing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

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

[0027] Figure 1 This is a schematic flowchart of a clothing shaking control method provided in an embodiment of the present invention. The clothing shaking control method provided in this embodiment is applicable to scenarios where clothing is dried using a clothing processing device. The clothing processing device has an inner drum and can be a household appliance with a drying function. For example, the clothing processing device can be a dryer, a washer-dryer combo, a garment care machine, etc.

[0028] Before formally introducing the clothing shaking control method provided in the embodiments of the present invention, let's first introduce the principle of detecting clothing entanglement in the present invention. The present invention uses an infrared temperature sensor to detect the surface temperature of an object, thereby realizing the detection of clothing entanglement.

[0029] Infrared temperature sensors detect the surface temperature of objects based on infrared radiation thermometry. All objects with a temperature above absolute zero (-273.15°C) radiate infrared radiation. Infrared temperature sensors determine the surface temperature of an object by detecting and analyzing this infrared radiation. An infrared temperature sensor typically consists of a lens system, a detector, a signal processing circuit, and a display or control circuit. The lens system focuses and collects the infrared radiation from the object; the detector converts the infrared radiation into an electrical signal; common detector types include thermopile detectors and thermistors; the signal processing circuit amplifies, digitizes, and processes the electrical signal, typically including an analog-to-digital converter and an amplifier; and the display or control circuit converts the processed data into a temperature reading.

[0030] In this embodiment, the infrared temperature sensor can be installed inside the garment processing equipment. Specifically, it can be installed above the inner drum, and one or more infrared temperature sensors can be installed. The infrared temperature sensor can scan downwards, with its viewing angle covering the entire measurement area from top to bottom. Alternatively, the infrared temperature sensor can be installed in other positions within the garment processing equipment that can illuminate the entire area inside the drum, such as directly in front of the inner drum. The infrared temperature sensor can also be configured to rotate at multiple angles, such as 360 degrees, to achieve comprehensive illumination of the inner drum without blind spots. The infrared temperature sensor can be a multi-point infrared temperature sensor, containing multiple infrared detection units. These infrared detection units form an array that can cover multiple measurement points. Each independent detection unit detects infrared radiation at a specific location, thereby simultaneously measuring the temperature of multiple points. The measured temperature data is presented in the form of an M×N matrix, where M and N are both integers greater than 1, that is, the detection area is divided into an M×N dot matrix, and the temperature data of each point is recorded independently. Infrared temperature sensors detect the temperature inside the inner drum in real time or at short intervals (e.g., 3s, 5s). The detected temperatures can include the surface temperature of the clothing and the temperature of the surrounding environment, such as the temperature of the inner drum wall, the temperature of the inner drum's lifting ribs, and the temperature of the air inside the inner drum. The temperature data is transmitted to the signal processing circuit in matrix form. The signal processing circuit is responsible for converting this data into digital signals for analysis by the control system of the clothing handling equipment.

[0031] In the initial stage of drying, the inner drum heats up while the clothes are damp. Due to moisture evaporation, the temperature of the clothes is lower than that of the drum wall. Therefore, the infrared temperature sensor detects relatively low temperature areas, which can be defined as "wet areas" or "cold areas." As the drying process progresses and the clothes gradually become dry, the area of ​​the "wet areas" or "cold areas" reflected in the temperature data will gradually decrease, and the temperature of the clothes will gradually rise, eventually approaching the temperature of the surrounding environment.

[0032] After the inner drum rotates for a period of time, as the clothes tumble and rub against each other, some clothes begin to entangle. Specifically, this manifests as a continuous decrease in the area or proportion of the "wet area" or "cold area" within the sensing range compared to the initial stage. Once the decrease in the area or proportion of the "wet area" or "cold area" exceeds a set threshold, it can be identified as a certain degree of entanglement. In this invention, during the drying process, as the clothes gradually approach dryness, a decrease in the area or proportion of the "wet area" or "cold area" is inevitable. However, because the infrared temperature sensor detects the temperature inside the inner drum in real time or at relatively short time intervals—meaning the entanglement detection time interval is very short—the improvement in the dryness of the clothes is very limited within a short period. Therefore, during the entanglement detection period, the decrease in the area or proportion of the "wet area" or "cold area" due to the drying of the clothes can be ignored.

[0033] Continue reading Figure 1 The clothing shaking control method of this embodiment may include the following steps:

[0034] Step 110: Use an infrared temperature sensor to detect the temperature inside the inner cylinder and obtain the temperature matrix data at the current moment.

[0035] The inner drum refers to the cylindrical body in a garment processing device used for placing and turning clothes. During the drying process, the inner drum rotates continuously, ensuring the clothes are heated and dried evenly. At any given moment, the inner drum can rotate in the current direction. This current direction can be clockwise, reverse, or counterclockwise. Temperature matrix data refers to temperature data collected by an infrared temperature sensor and presented in matrix form, where each point in the matrix corresponds to the temperature value at a specific location within the inner drum.

[0036] At the current moment, the inner drum of the garment processing equipment is rotating in the current direction. Infrared temperature sensors are used to monitor the temperature at various locations inside the inner drum in real time, thereby obtaining a temperature matrix data. This temperature matrix data can include the current temperature of the garment surface and the temperature of the surrounding environment.

[0037] Step 120: Mark the areas corresponding to points in the temperature matrix data where the temperature is lower than the preset temperature as the areas of undried clothes at this time.

[0038] The undried area typically represents parts of clothing where moisture has not completely evaporated; it can be the previously mentioned "wet area" or "cold area." Specifically, a temperature threshold, or preset temperature, can be pre-set as the boundary between dry and undried. For example, if the temperature at a point inside the drum is below the temperature threshold, the clothing at that point is considered undried. The temperature matrix can be iterated through to mark points below the temperature threshold, thus identifying low-temperature points. These low-temperature points correspond to specific locations inside the drum, and these locations constitute the undried area at that moment, allowing for the marking of this undried area.

[0039] Temperature thresholds can be set based on experimental data. For example, temperature changes during the drying process of different fabrics can be measured experimentally to obtain reference data on the temperature of dried clothes, which can then be used to set the temperature threshold. Temperature thresholds can also be set based on empirical values. For instance, the final drying temperature for common fabrics may be between 45℃ and 60℃, and an intermediate value can be chosen as the temperature threshold. Furthermore, the drying process is also affected by external environmental factors, such as ambient temperature and humidity. Therefore, the temperature threshold setting can also take these external factors into account and can be adjusted in real time as needed. Setting a reasonable temperature threshold can accurately identify areas of undried clothing, thereby improving the accuracy of clothing entanglement detection.

[0040] Step 130: Determine the trend of changes in the undried clothing area, and control the clothing processing equipment to shake and disperse the clothing according to the corresponding trend.

[0041] In this embodiment, the trend of changes in the undried clothing area within a preset time period can be determined. The preset time period can include the time from the start of drying to the start of the first shake, or the time from the end of one shake to the start of another. The specific duration of each preset time period is determined based on the speed at which clothing tangling occurs, and is not fixed. If tangling occurs slowly, the duration of a preset time period will be longer; if tangling occurs quickly, the duration of a preset time period will be shorter. For example, if clothing tangling occurs within 2 minutes, a preset time period may be 2 minutes; if clothing tangling occurs within 5 minutes, a preset time period may be 5 minutes. Traditional drum control cycles are fixed. For example, a fixed 1 minute, i.e., 1 minute clockwise rotation followed by 1 minute counterclockwise rotation. Therefore, the preset time period in this embodiment differs from the traditional drum control cycle.

[0042] The system can determine whether clothing tangling has occurred based on the trend of changes in the undried clothing area. If tangling has occurred, the clothing handling equipment is controlled to shake and disperse the clothing. The trend of changes in the undried clothing area can refer to changes in the size of the area or changes in the proportion of the undried clothing area within the overall detection area. The system can calculate the current area of ​​the undried clothing area and compare it with the largest area of ​​the undried clothing area within the current period (i.e., the current preset time period). If the deviation exceeds a set area threshold, clothing tangling is determined. The system can also calculate the proportion of the undried clothing area within the overall detection area at the current moment and compare it with the largest proportion of the undried clothing area within the current period. If the decrease exceeds a set threshold, clothing tangling is determined. These thresholds can be set based on experiments, experience, or actual needs.

[0043] Clothes tangling is a phenomenon that occurs when clothes inside the inner drum become tangled and piled up during the tumbling process. This can prevent wet areas from being exposed in time, and cause some clothes to not be heated evenly or dry inefficiently.

[0044] When clothing tangling is detected, the clothing handling equipment can be immediately controlled to shake the clothes apart. The shaking process can be reverse rotation or alternating forward and reverse rotation. Reversal rotation can be controlling the inner drum to rotate in the opposite direction of the current direction. If the current direction is forward or clockwise, the opposite direction can be reverse or counterclockwise; conversely, if the current direction is reverse or counterclockwise, the opposite direction is forward or clockwise. When clothing tangles occur inside the inner drum at the current moment, a reverse rotation command can be sent to the motor controller. The motor controller receives the command and executes it immediately, and the inner drum begins to rotate in the opposite direction. Through the reverse force, the clothes inside the inner drum can be shaken apart quickly, untangling them and exposing more of the wet area. In this embodiment, the forward and reverse rotation of the inner drum is no longer controlled according to a fixed cycle, but rather according to whether the clothes are tangled, or in other words, a variable cycle control determined by the speed of tangling. If clothes are tangled, the inner drum is immediately controlled to rotate in the opposite direction; if the clothes are not tangled, the current rotation direction of the inner drum remains unchanged.

[0045] In this embodiment, an infrared temperature sensor can be used to acquire real-time temperature data within the inner drum. The area of ​​undried clothing is then identified based on this data, and the tangling of clothing is dynamically identified based on the changing trends of these areas. Infrared non-contact detection ensures the reliability of the detection system. Instead of a fixed cycle, the clothing handling equipment is directly controlled to shake and disperse the clothing based on the changing trends of the undried areas. This real-time response mechanism quickly resolves tangling issues. Timely and precise shaking exposes the undried areas, improving drying uniformity and shortening drying time, thus increasing overall drying efficiency. Intelligent detection and control maintain uniform heating and drying of clothing, preventing uneven drying caused by prolonged accumulation in one area. Furthermore, immediate shaking reduces excessive friction caused by tangling, significantly lowering the risk of wear and tear and preserving the original shape and texture of the clothing.

[0046] The following further describes the clothing shaking control method provided by the embodiments of the present invention, such as... Figure 2 As shown, the method in this embodiment includes:

[0047] Step 210: Use an infrared temperature sensor to detect the temperature inside the inner cylinder and obtain the temperature matrix data at the current moment.

[0048] Infrared temperature sensors can be positioned to detect the entire interior of the inner cylinder; one or more infrared temperature sensors can be installed. For example, such as... Figure 3a As shown, the infrared temperature sensor can be set at the front upper part of the inner cylinder, with its viewing angle covering the entire measurement area from top to bottom.

[0049] Step 220: Identify points with temperatures lower than the preset temperature from the current temperature matrix data to obtain the low temperature points.

[0050] The preset temperature is a pre-set boundary temperature that distinguishes between dry and undried conditions; it is also known as the temperature threshold. If the temperature at a certain point inside the inner drum is lower than the temperature threshold, then that point is a low-temperature point, and the clothes at that point are not yet dry.

[0051] Step 230: Mark the area of ​​undried clothes at this time based on the temperature dot matrix data at the current moment.

[0052] The temperature data at a given moment can contain multiple low-temperature points. The areas corresponding to these low-temperature points constitute the undried clothing areas at that moment. Dried clothing areas typically represent parts of clothing where moisture has not completely evaporated.

[0053] For example, the temperature matrix data at the current moment is as follows: Figure 3bAs shown, assuming the preset temperature is 50℃, meaning points below 50℃ are considered low-temperature points, the current area of ​​undried clothing can be represented as follows: Figure 3b The gray area is shown. The size of the undried clothes area can be represented by the number of low-temperature points that make up the undried clothes area, or by the actual area of ​​the undried clothes area in the inner drum. Figure 3b In the example shown, if the size of the undried clothes area is represented by the number of low-temperature points that constitute the undried clothes area, then the size of the undried clothes area at the current moment can be represented as 41, that is, the undried clothes area at the current moment is composed of 41 low-temperature points.

[0054] After identifying the area of ​​undried clothing at the current moment, either step 240 or step 250 can be used for entanglement detection and processing.

[0055] Step 240: Calculate the area of ​​undried clothes at the current moment and compare it with the area of ​​the largest undried clothes in this cycle. If the deviation value is greater than the set area threshold, control the clothes processing equipment to shake and disperse the clothes.

[0056] The area of ​​undried clothing at the current moment can be represented by the number of low-temperature points in the temperature matrix data at the current moment.

[0057] Historical temperature data can be used to identify the historical trend of undried areas, and the area of ​​the largest undried clothing area in the current period can be determined based on the historical trend of undried areas.

[0058] A historical moment is a moment prior to the current moment. At a historical moment, the inner drum is still rotating in the current direction. That is, during the period when the tangling is determined, the inner drum does not change its rotation direction. Assuming the inner drum is currently rotating clockwise, and the temperature inside the inner drum is collected every 1 second, the temperature data at each historical moment can include temperature data collected 1 second, 2 seconds, 3 seconds, etc., before the current moment during the clockwise rotation of the inner drum. The method for identifying the undried clothing area at each historical moment can be the same as or similar to the method for identifying the undried clothing area at the current moment, and will not be elaborated here.

[0059] The historical trend of undried areas refers to the trend of changes in undried clothing areas before the current moment. By comparing undried clothing areas at consecutive historical points in time, we can analyze their changes in area, quantity, etc., over time, and thus obtain the historical trend of undried areas.

[0060] In practice, the historical trend of the undried area can be either continuously decreasing or initially increasing and then decreasing. At the start of the garment handling equipment, the garments are not tangled and are fully wet, resulting in a maximum undried area. The inner drum rotates in one direction. After a period of time, tangling begins, and the undried area starts to decrease. In this case, the historical trend of the undried area will be continuously decreasing. Once tangling is detected, the undried area will have a smaller or minimum value. The equipment will then rotate in the opposite direction, gradually untangling the garments. As the tangling is resolved, the undried area slowly increases. The inner drum continues to rotate, and after a period of time, tangling begins again, and the undried area starts to decrease again. In this case, the historical trend of the undried area will be initially increasing and then decreasing. In other words, at the start of the garment handling equipment, the historical trend of the undried area is continuously decreasing. After one instance of tangling and subsequent untangling, the historical trend of the undried area will consistently be initially increasing and then decreasing throughout the subsequent cycle. Therefore, in this embodiment, the preset time period can be defined as the time period from the start of drying to the start of the first shaking, or it can be defined as the time period from the end of one shaking to the start of another shaking.

[0061] If the historical trend of the undried area is consistently decreasing, it indicates that the garment processing equipment is currently in its initial stage and garment tangling has begun. If the historical trend of the undried area is not consistently decreasing, but rather initially increasing and then decreasing, it indicates that the garment is currently in a cycle following one shaking process.

[0062] If the historical trend of the undried area is consistently decreasing, the earliest time can be determined from various historical moments, and the area of ​​the undried clothing at the earliest time can be defined as the largest area of ​​undried clothing within this cycle. The earliest time could be the moment when the clothing processing equipment is started, at which point no clothing tangling has occurred. The area of ​​the undried clothing before tangling can be defined as the largest area of ​​undried clothing within this cycle (i.e., the current preset time period).

[0063] If the historical trend of the undried area is first increasing and then decreasing, the inflection point of the change in the undried area can be determined from various historical moments. The area of ​​the undried clothing at the inflection point is determined as the maximum area of ​​the undried clothing within this period. The inflection point can be the moment when the undried clothing area begins to decrease after reaching its maximum. At this moment, the tangled clothing is completely shaken apart by the mechanical force of the reverse rotation. The area of ​​the undried clothing at the moment when it is completely shaken apart is determined as the maximum area of ​​the undried clothing within this period.

[0064] For example, in the first second, the garment handling equipment starts, the inner drum begins to rotate clockwise, all the clothes are wet, and the undried area reaches its maximum value. Afterwards, tangling gradually begins, and tangling is detected in the tenth second, at which point the undried area reaches its minimum value. Then, the inner drum is controlled to rotate counter-clockwise, which disperses the clothes, and the undried area begins to increase. By the fifteenth second, the counter-clockwise rotation completely disperses the clothes, and the undried area reaches its maximum value. By the twenty-fifth second, the rotation is still reversed, the clothes begin to tangle again, and the undried area begins to decrease. Therefore, the area of ​​undried clothes detected in the first second can be determined as the maximum undried area for the corresponding cycle in the clockwise direction, and the area of ​​undried clothes detected in the fifteenth second can be determined as the maximum undried area for the corresponding cycle in the counter-clockwise direction.

[0065] The maximum undried area in this cycle can also be represented by the number of low-temperature points within that area. The area difference can be calculated by subtracting the current undried area from the maximum undried area in this cycle. If the area difference exceeds a set area threshold, the clothing is considered tangled, and the clothing handling equipment is controlled to shake and disperse the clothing. The set area threshold is a pre-defined threshold in the system used as a standard for judging whether clothing is tangled; it can be set based on experiments or experience. When the area difference exceeds this threshold, it indicates that clothing is tangled.

[0066] For example, the maximum undried area in this cycle is 80, the current undried clothing area is 20, the set area threshold is 30, and the current area difference is 60. If the area difference exceeds the set area threshold of 30, it is determined that clothing tangling has occurred at the current moment. In this case, the inner drum can be controlled to rotate in the opposite direction of the current direction for a period of time, or the inner drum can be controlled to rotate in both directions for a period of time to shake the clothing.

[0067] Step 250: Calculate the proportion of the undried clothing area in the overall detection area at the current moment, obtain the proportion of the undried clothing area, and compare it with the largest proportion of the undried clothing area in this cycle. If the decrease exceeds the set threshold, control the clothing processing equipment to shake the clothes.

[0068] The overall detection area can be the entire area inside the inner drum that is being detected. The current percentage of undried clothing is the ratio of the area of ​​undried clothing to the area of ​​the overall detection area, which can be expressed as the ratio of the number of points in the undried clothing area to the number of points in the overall detection area. For example, Figure 3b In the example shown, the number of points in the undried clothing area at the current moment is 41, and the total number of points in the overall detection area is 150. Therefore, the proportion of the undried clothing area at the current moment is 41 / 150, or 27%. Similarly, the proportion of the largest undried clothing area in this period can be represented by the ratio of the number of points corresponding to the largest undried clothing area to the number of points in the overall detection area.

[0069] The percentage difference can be obtained by subtracting the percentage of undried clothes at the current moment from the percentage of the largest undried clothes area within the current period. When the percentage difference exceeds a set threshold, it is determined that clothes tangling has occurred at the current moment.

[0070] The threshold is a preset numerical limit used to determine whether the percentage difference is normal and whether intervention is needed. The threshold can be set based on experience or experimental data. For example, the threshold could be 0.05, 0.1, etc. If the percentage difference exceeds this threshold, it indicates that the area of ​​undried clothing decreased significantly during this entanglement detection period, indicating clothing entanglement, and the degree of entanglement is severe, requiring intervention. If the percentage difference does not exceed this threshold, it indicates that no clothing entanglement occurred during this entanglement detection period, or clothing entanglement occurred, but the degree of entanglement is minor, and no intervention is needed at this time.

[0071] When it is determined that clothes are tangled at the current moment, a reverse command can be sent to the motor controller. The motor controller receives the command and executes it immediately. The inner drum begins to rotate in the opposite direction. Through the reverse force, the clothes in the inner drum can be shaken off as quickly as possible and the tangled state can be resolved.

[0072] By referring to the area or percentage of the largest undried clothing area within the current cycle, the system determines whether clothing is tangled inside the drum at any given moment. This approach considers the varying impacts of rotation patterns in different directions and cycles on clothing distribution and drying, allowing for more accurate identification of tangles. Furthermore, the area or percentage of the largest undried clothing area within the current cycle is dynamically determined in real-time, making it even more valuable for judging tangling at the current moment. Using this as a benchmark avoids misinterpreting normal changes in undried areas due to different rotation directions or cycle periods as tangling.

[0073] Additionally, the current trend of the undried area can be determined based on the previous and current undried area measurements. The current trend refers to the change in the undried area at the current moment, including whether it is increasing or decreasing. For example, if the size of the undried area at the previous moment was 41 and the current size is 28, the current trend is decreasing. If the size of the undried area at the previous moment was 41 and the current size is 50, the current trend is increasing. If the current trend is increasing, it indicates that the tangled clothes are being shaken out by the rotational force of the inner drum.

[0074] When the current trend of the undried area is decreasing, it is determined that clothes are tangled inside the drum at the current moment. Reverse rotation can be initiated as soon as tangling is detected, or it can be initiated when tangling occurs and the degree of tangling exceeds a preset tangling level. The degree of tangling can be determined based on the difference between the current undried area and a reference undried area. The greater the difference, the more severe the tangling. The reference undried area can be the largest undried area within this cycle, or the largest undried area detected in the current drying stage.

[0075] The preset tangling level is a pre-set threshold used to determine whether to initiate reverse rotation. By presetting the tangling level, the garment handling equipment can activate anti-tangling measures before the tangling problem becomes severe, providing early warning and prevention to avoid damage to clothing. Furthermore, preset tangling levels allow the garment handling equipment to initiate corrective measures at the most appropriate time, rather than reversing operation every time slight tangling is detected, optimizing equipment performance and service life. Timely and effective handling of tangled clothing exposes undried areas promptly, reducing ineffective drying time and energy consumption, improving energy efficiency, and saving drying time.

[0076] In this embodiment, an infrared temperature sensor can be used to acquire real-time temperature data within the inner drum. The area of ​​undried clothing is then identified based on this data, and the tangling of clothing is dynamically identified based on the changing trends of these areas. Infrared non-contact detection ensures the reliability of the detection system. Instead of a fixed cycle, the clothing handling equipment is directly controlled to shake and disperse the clothing based on the changing trends of the undried areas. This real-time response mechanism quickly resolves tangling issues. Timely and precise shaking exposes the undried areas, improving drying uniformity and shortening drying time, thus increasing overall drying efficiency. Intelligent detection and control maintain uniform heating and drying of clothing, preventing uneven drying caused by prolonged accumulation in one area. Furthermore, immediate shaking reduces excessive friction caused by tangling, significantly lowering the risk of wear and tear and preserving the original shape and texture of the clothing.
