[0006] In some embodiments, the first determination includes obtaining the water absorption parameters of the fabric inside the fabric treatment tube and determining the first determination result based on the water absorption parameters.

[0007] In some embodiments, the water absorption parameters include one or more of water absorption rate, saturated weight, and water absorption rate; wherein the water absorption rate is the amount of weight increase of the fabric by water absorption per unit time, the saturated weight is the weight of the fabric when it stops absorbing water, and the water absorption rate is the ratio of the difference between the saturated weight of the fabric and the dry weight of the fabric to the dry weight of the fabric.

[0008] In some embodiments, if the water absorption rate is greater than a preset water absorption rate and / or the saturated weight is greater than a preset saturated weight and / or the water absorption rate is greater than a preset water absorption rate, the first determination result is that the fabric has high water absorption characteristics; if the water absorption rate is less than or equal to a preset water absorption rate and / or the saturated weight is less than or equal to a preset saturated weight and / or the water absorption rate is less than or equal to a preset water absorption rate, the first determination result is that the fabric has low water absorption characteristics.

[0010] In some embodiments, determining the washing parameters of the washing program based on the material of the fabric to be washed includes: if the fabric type is a highly absorbent and easily tangled material, then controlling the washing mode of the fabric treatment device to wash at a first speed and dehydrate at a second speed; if the fabric type is a highly absorbent and non-tangled material, then controlling the washing mode of the fabric treatment device to wash at a third speed and dehydrate at a fourth speed; if the fabric type is a low-absorbent and easily tangled material, then controlling the washing mode of the fabric treatment device to wash at a fifth speed and dehydrate at a sixth speed; if the fabric type is a low-absorbent and non-tangled material, then controlling the washing mode of the fabric treatment device to wash at a seventh speed and dehydrate at an eighth speed; wherein, the third speed > the first speed > the fifth speed > the seventh speed, and the fourth speed > the second speed > the sixth speed > the eighth speed.

[0011] In some embodiments, if the fabric type is a highly absorbent and easily tangled material, the frequency at which the fabric processing cylinder alternates between forward and reverse rotation is higher than a preset frequency.

[0012] In some embodiments, the dehydration time at the eighth rotation speed is less than the second preset dehydration time, or the eighth rotation speed is equal to zero.

[0015] The solution provided by this invention has the following advantages compared with the prior art: The fabric material judgment method is based on a first judgment stage to judge the water absorption characteristics of the fabric, and a second judgment stage to monitor the mechanical response of the inner drum and judge whether the fabric is prone to tangling. After the initial judgment, a brief, diagnostic micro-circulation of gentle washing and low-speed dehydration is introduced. During this process, the dynamic behavior of the fabric under mechanical action is analyzed by monitoring the real-time load current fluctuation of the motor, verifying and refining the initial judgment results, and finally confirming the material type. This phased judgment method improves the accuracy of material identification by combining the initial judgment with the final confirmation. Based on the confirmed material type, the system automatically calls and sets the most suitable dehydration parameters for the material from the preset parameter library, without relying on manual selection by the user. It automatically adapts to different fabric combinations each time. By analyzing the overall characteristics of the fabric, it can provide a comprehensive and optimal washing solution for mixed material fabric loads, improve the adaptability of mixed washing, and avoid fabric damage caused by improper program selection.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] Existing washing machines typically require users to manually select the washing program based on the fabric material (such as cotton, linen, silk, wool, etc.). This method has significant drawbacks: it is highly dependent on the user; users must have some knowledge of fabric materials, otherwise incorrect selection may lead to fabric damage (such as using a wool program to wash silk) or poor washing results (such as a standard program washing a down jacket causing it to explode).

[0021] Based on this, the following embodiments are proposed.

[0022] Example 1: As shown in Figure 1, this example provides a fabric material determination method, including: a first determination stage, which is used to make a first determination on the fabric material in the fabric treatment drum before the start of washing, and obtain a first determination result; a second determination stage, which is executed after the first determination stage, in which the magnitude of the motor current fluctuation of the fabric treatment drum is monitored, and the fabric material is made a second determination based on the magnitude of the motor current fluctuation, and a second determination result is obtained; the final fabric material is determined based on the first determination result and the second determination result.

[0023] In this embodiment, the first judgment stage makes a first judgment on the fabric material in the fabric processing tube. The means of identifying the fabric material used in the first judgment stage can be to identify the fabric material by parameters related to water absorption, such as the fabric's water absorption rate, saturated weight, and water absorption percentage. For example, if the fabric has a high water absorption rate, a large water absorption percentage, and a saturated weight that is significantly higher than its dry weight, then the fabric is cotton or a heavy type of material, such as a pure cotton shirt or towel. If the fabric has a low water absorption rate, a small water absorption percentage, and a saturated weight that is not much different from its dry weight, then the fabric is silk, chemical fiber, or down jacket type of material. The means of identifying the fabric material used in the first judgment stage can also be image recognition, optical sensor recognition, or manual input, thereby completing the first judgment on the fabric and having a first judgment result. The second judgment stage is performed after the first judgment stage. In the second judgment stage, a brief wash is performed to ensure the fabric is fully wetted and in contact with water, followed by a brief spin-drying. The magnitude of the motor current fluctuation is monitored. If the motor current fluctuation is small, it indicates that the motor current is stable, and the second judgment result is that the fabric has the characteristics of not easily tangling and being evenly distributed. If the motor current fluctuation is large, it indicates that there is eccentricity in the inner drum of the fabric processing drum. The motor current needs to be constantly adjusted to balance the torque, resulting in periodic or violent fluctuations in the current, and the second judgment result is that the fabric has the characteristic of easily tangling into clumps. The final fabric material is determined based on the results of the first and second judgment stages. For example, cotton / linen / shirts: have high water absorption characteristics, and the load is relatively stable during spin-drying because they are not easily severely tangled. Down jackets: have high water absorption characteristics, and the internal down will eventually absorb water, but during spin-drying, because down jackets are easily tangled into a large clump after getting wet, severe eccentricity occurs, resulting in large fluctuations in the motor current. Silk: It has low water absorption characteristics, and its smooth texture during dehydration makes it less prone to tangling, resulting in smaller fluctuations in motor current. Wool also has low water absorption characteristics. Wool itself absorbs water but not quickly, and it is often accompanied by a protective cover during washing. However, the load may fluctuate during dehydration, and wool fibers are prone to entanglement and shrinkage under mechanical action. Even in a short time, an unstable trend can be detected, leading to large fluctuations in motor current. Therefore, the fabric material judgment method proposed in this embodiment makes a preliminary judgment on the fabric material type in the first judgment stage, and then uses the fabric processing equipment to enter a diagnostic micro-circulation in the second judgment stage to re-judge the fabric material. The final fabric material is determined by the first and second judgment results. This method is not only accurate, but the final judgment result is also more targeted, making it easier for the fabric processing equipment to adopt targeted washing, dehydration, drying, and care modes based on the judgment result.

[0024] The fabric material identification method proposed in this embodiment eliminates the risk of user misoperation: by automatically identifying the material, it avoids fabric damage caused by improper program selection, and provides convenient judgment conditions for subsequent selection of a precise and suitable washing mode. By dynamically setting the optimal washing parameters for different materials, especially spin speed, time, and forward and reverse rotation frequency, it ensures the cleanliness of the fabric while protecting it to the maximum extent. By analyzing the overall characteristics of the fabric, it can provide a comprehensive and optimal washing solution for mixed material fabric loads, improving the adaptability of mixed washing. Especially for materials such as down jackets and wool that are prone to problems in the spin-drying process, by accurately predicting the fabric material characteristics and subsequently adjusting the parameters, it can effectively prevent problems such as tangling, eccentricity, and damage, enhancing the safety of fabric washing.

[0025] The fabric material identification method proposed in this embodiment is based on a first identification stage to determine the fabric's water absorption characteristics. A second identification stage monitors the inner drum's mechanical response to assess the fabric's tangling tendency. After the initial identification, a brief, diagnostic micro-cycle of gentle washing and low-speed spin-drying is introduced. During this process, the real-time load current fluctuations of the motor are monitored to analyze the fabric's dynamic behavior under mechanical action, such as its tangling tendency. This verifies and refines the initial identification results, ultimately confirming the material type. This phased identification method improves the accuracy of material identification by combining the initial identification with the final confirmation. Simultaneously, trial spin-drying is performed before high-risk operations to minimize fabric damage caused by misjudgment. Based on the confirmed material type, the system automatically retrieves and sets the most suitable spin-drying parameters from a preset parameter library, without relying on manual user selection, and automatically adapts to different fabric combinations each time.

[0026] As shown in Figure 2, the first judgment result includes whether the fabric has high water absorption characteristics or low water absorption characteristics.

[0027] In this embodiment, the first judgment stage performs a first judgment on the fabric material inside the fabric treatment cylinder. The method used in the first judgment stage to identify the fabric material can be through water absorption-related parameters such as the fabric's water absorption rate, saturated weight, and water absorption percentage. For example, if the fabric has a high water absorption rate, a high water absorption percentage, and a saturated weight that is significantly higher than its dry weight, then the fabric is cotton or a heavy type of material, such as pure cotton shirts or towels. This type of fabric is a highly absorbent and heat-resistant fabric. Conversely, if the fabric has a low water absorption rate, a low water absorption percentage, and a saturated weight that is not much different from its dry weight, then the fabric is silk, synthetic fiber, or down jacket type. Regarding the material, this type of fabric is a low-absorbency fabric. The identification method for the fabric material in the first judgment stage can also be image recognition, optical sensor recognition, or manual input, thereby completing the first judgment of the fabric and having the first judgment result, that is, the fabric is high-absorbency or low-absorbency. The first stage of judgment can provide a preliminary identification of the material type of the fabric, classifying the fabric into high-absorbency and low-absorbency, providing basic data for the second stage of judgment, and classifying the fabric into two types of absorbency based on absorbency characteristics, the classification method is simpler and more direct, avoiding the problems of misjudgment caused by multiple types of material identification.

[0028] As shown in Figure 2, the second judgment on the fabric material based on the magnitude of the motor current fluctuation includes: if the motor current fluctuation is greater than a preset fluctuation threshold, the second judgment result is that the fabric is easy to tangle; if the motor current fluctuation is less than or equal to the preset fluctuation threshold, the second judgment result is that the fabric is not easy to tangle.

[0029] In this embodiment, during the second judgment stage, the fluctuation of the motor current is monitored during the brief dehydration process of the fabric processing drum. If the motor current fluctuation is less than or equal to the preset fluctuation threshold, the second judgment result is that the fabric is not easily tangled. This indicates that the motor current is stable, and the second judgment result indicates that the fabric has the characteristics of being not easily tangled and having a uniform distribution. If the motor current fluctuation is greater than the preset fluctuation threshold, the second judgment result is that the fabric is easily tangled. This indicates that the inner drum of the fabric processing drum is eccentric, and the motor current needs to be constantly adjusted to balance the torque, resulting in periodic or violent fluctuations in the current. The second judgment result is either that the fabric is easily tangled or that it is not easily tangled. Dividing the second judgment result into two categories, it is easier to determine the most prominent characteristic of the final fabric material based on the first judgment result and the second judgment result. This is not only accurate but also makes the final judgment result more targeted, allowing the fabric processing equipment to adopt targeted washing, dehydration, drying, and care modes based on the judgment result.

[0030] As shown in Figure 2, determining the final fabric material based on the first judgment result and the second judgment result includes: if the first judgment result indicates high water absorption and the second judgment result indicates that the fabric is prone to tangling, the final fabric material is determined to be a high water absorption and tangling material; if the first judgment result indicates high water absorption and the second judgment result indicates that the fabric is not prone to tangling, the final fabric material is determined to be a high water absorption and non-tangling material; if the first judgment result indicates low water absorption and the second judgment result indicates that the fabric is prone to tangling, the final fabric material is determined to be a low water absorption and tangling material; if the first judgment result indicates low water absorption and the second judgment result indicates that the fabric is not prone to tangling, the final fabric material is determined to be a low water absorption and non-tangling material.

[0031] In this embodiment, the final fabric material is determined based on the first judgment result and the second judgment result, including highly absorbent and easily tangled materials, highly absorbent and non-tangled materials, low-absorbent and easily tangled materials, and low-absorbent and non-tangled materials. Highly absorbent and easily tangled materials include down jackets. Down jackets have high water absorption characteristics, and the down inside will eventually absorb water. However, during dehydration, the down jacket is prone to tangling into a large ball after getting wet, which causes serious eccentricity and leads to large fluctuations in motor current. Highly absorbent and non-tangled materials include cotton, linen, or shirts. Cotton, linen, or shirts have high water absorption characteristics, and the load is relatively stable during dehydration because they are not prone to serious tangling. Materials with low water absorption and easy tangling, such as wool, have low water absorption characteristics. Wool itself absorbs water but not quickly, and is often accompanied by a protective cover during washing. However, the load may fluctuate during spin drying, and wool fibers are prone to tangling and shrinking under mechanical action. Even if the time is short, an unstable trend can be detected, resulting in large fluctuations in motor current. Materials with low water absorption and non-tangling, such as silk, have low water absorption characteristics. Silk has a smooth texture during spin drying and is not easy to tangle, resulting in smaller fluctuations in motor current.

[0032] The fabric processing equipment can adopt targeted washing, dehydration, drying and care modes according to the final fabric material, which can not only clean the fabric more efficiently, but also avoid damage to the fabric due to excessive fabric strength.

[0033] Optionally, in one implementation of this embodiment, as shown in FIG3, the second determination stage includes: after the water intake is completed, performing a gentle wash process for a first preset time, during which the fabric processing drum is controlled to rotate in both directions; after the gentle wash process ends, performing a drainage process for a second preset time; after the drainage process ends, performing a dehydration process for a third preset time, during which the fabric processing drum is controlled to rotate at a preset speed; and monitoring the magnitude of the motor current fluctuation of the fabric processing drum during the dehydration process.

[0034] In this embodiment, during the second judgment stage, the fabric processing drum is first controlled to enter a gentle washing process. It can be understood that this gentle washing process is not the main washing program of the fabric processing equipment, but a short and gentle washing process designed for fabric material judgment. For example, this gentle washing process involves performing a 1-2 minute forward and reverse gentle wash to ensure that the fabric is fully wetted and in contact with water. Then, the fabric processing drum is controlled to enter the drainage process. After the drainage process is completed, a third preset time dehydration process is performed. This dehydration process is not the main dehydration program of the fabric processing equipment, but a short and low-speed dehydration program designed for fabric material judgment. For example, after the gentle washing process is completed, a short drainage is performed, and the fabric processing drum rotates at 400 rpm for 30 seconds of dehydration. During this process, the magnitude of the motor current fluctuation of the fabric processing drum is monitored to obtain parameters of the motor current fluctuation.

[0035] Optionally, in one implementation of this embodiment, the first judgment includes acquiring the water absorption parameters of the fabric inside the fabric treatment cylinder, and determining the first judgment result based on the water absorption parameters. Preferably, the water absorption parameters include one or more of water absorption rate, saturated weight, and water absorption rate; wherein, the water absorption rate is the increase in weight of the fabric by water absorption per unit time, the saturated weight is the weight of the fabric when it stops absorbing water, and the water absorption rate is the ratio of the difference between the saturated weight of the fabric and the dry weight of the fabric to the dry weight of the fabric.

[0036] Furthermore, if the water absorption rate is greater than a preset water absorption rate and / or the saturated weight is greater than a preset saturated weight and / or the water absorption rate is greater than a preset water absorption rate, the first determination result is that the fabric has high water absorption characteristics; if the water absorption rate is less than or equal to a preset water absorption rate and / or the saturated weight is less than or equal to a preset saturated weight and / or the water absorption rate is less than or equal to a preset water absorption rate, the first determination result is that the fabric has low water absorption characteristics.

[0037] In this embodiment, the first judgment includes obtaining the water absorption parameters of the fabric in the fabric treatment cylinder and determining the first judgment result based on the water absorption parameters. The water absorption parameters can be detected using existing components such as water level sensors, weight sensors and inlet flow meters in the fabric treatment equipment, without the need to add special hardware such as optical material sensors. The structure is simple and the cost is low.

[0038] As shown in Figure 3, in the first judgment stage, the dry weight and water intake are analyzed first. The initial dry weight detection is performed by closing the hatch and slowly rotating the inner cylinder several times to allow the fabric to be evenly distributed. Then, the stable dry weight data W_dry is obtained through the weight sensor, and water intake begins. The flow meter records the water intake volume V_in, the water level sensor monitors the real-time water level H, and the weight sensor monitors the real-time weight W_current. For the calculation of key indicators: water absorption rate: the increase in weight per unit time (W_current - W_dry) / t.

[0039] Saturated weight: The wet weight of the fabric when the water level is stable and no further replenishment of water is needed (W_saturated).

[0040] Water absorption: (W_saturated - W_dry) / W_dry.

[0041] In this embodiment, the first judgment result is determined by the above-mentioned water absorption parameters. For example, if the fabric has a high water absorption rate and a large water absorption percentage, and the saturated weight is significantly higher than the dry weight, then the fabric is cotton or a heavy type of material, such as pure cotton shirts or towels. This type of fabric is a highly absorbent and heat-resistant fabric. On the other hand, if the fabric has a low water absorption rate and a small water absorption percentage, and the saturated weight is not much different from the dry weight, then the fabric is silk, chemical fiber, or down jacket type of material. This type of fabric is a low-absorbency fabric. This allows for a preliminary identification of the fabric's material type. The first judgment result classifies the fabric into high-absorbency and low-absorbency types, providing basic data for the second stage of judgment. Furthermore, classifying fabrics into high and low absorbency types based on their water absorption characteristics makes the classification method simpler and more direct, avoiding problems such as misjudgment caused by the identification of multiple material types.

[0042] Example 2 This example provides an operation control method for a fabric processing device, including: the fabric processing device determining the material of the fabric to be washed based on the fabric material determination method described in Example 1; and determining the washing parameters of the washing program based on the material of the fabric to be washed.

[0043] In this embodiment, since the operation control method of the fabric processing equipment includes the fabric material determination method in Embodiment 1, the control method has all the beneficial effects of the fabric material determination method in Embodiment 1.

[0044] Optionally, in one implementation of this embodiment, as shown in FIG2, after determining the final fabric material based on the first judgment result and the second judgment result, the washing mode of the fabric processing equipment is determined based on the final material; if the fabric type is a highly absorbent and easily tangled material, the washing mode of the fabric processing equipment is controlled to wash at a first speed and dehydrate at a second speed; if the fabric type is a highly absorbent and non-tangled material, the washing mode of the fabric processing equipment is controlled to wash at a third speed and dehydrate at a fourth speed; if the fabric type is a low-absorbent and easily tangled material, the washing mode of the fabric processing equipment is controlled to wash at a fifth speed and dehydrate at a sixth speed; if the fabric type is a low-absorbent and non-tangled material, the washing mode of the fabric processing equipment is controlled to wash at a seventh speed and dehydrate at an eighth speed; wherein, the third speed > the first speed > the fifth speed > the seventh speed, and the fourth speed > the second speed > the sixth speed > the eighth speed.

[0045] In this embodiment, the final fabric material is determined based on the first and second judgment results, including four categories: highly absorbent and easily tangled materials, highly absorbent and non-tangled materials, low absorbent and easily tangled materials, and low absorbent and non-tangled materials. The washing mode and spin speed are different for each of the four types of materials, and the spin-drying mode and spin speed are also different for each of the four types of materials, so as to achieve targeted washing and spin-drying for the four types of materials.

[0046] In this embodiment, the advantage of the washing mode rotation speed relationship is that high-absorbency materials are matched with high rotation speeds to ensure cleaning power. High-absorbency fabrics become heavier and have stronger stain adhesion after absorbing water, so the higher speeds (third and first) provide sufficient washing impact to prevent stain residue. Low-absorbency materials correspond to relatively lower speeds, balancing cleaning and protection. Stains on low-absorbency fabrics are easily removed, and the fifth and seventh speeds are set to complete cleaning while avoiding excessive pulling on thin, non-absorbent fabrics that could damage them due to high speeds. Materials prone to tangling require relatively lower speeds to reduce tangling damage and unnecessary slowing of washing efficiency. At the same absorbency level, designing lower speeds for washing modes corresponding to easily tangled materials effectively reduces fiber entanglement, prevents fabric deformation or wear, and avoids slowing down the washing process due to tangling.

[0047] The advantage of the spin speed ratio in the dehydration mode is that high absorbency materials are matched with high speeds to improve dehydration efficiency. High absorbency fabrics contain a lot of moisture, and the fourth and second speeds can quickly remove the moisture, shortening the drying or tumble drying time and saving energy. Low absorbency materials use low speeds to reduce fabric wear. Low absorbency fabrics themselves contain less moisture, and the sixth and eighth speeds are sufficient to meet the dehydration needs. Low speeds can also reduce the impact of centrifugal force on the fabric and protect the fiber structure. Easily tangled materials correspond to relatively lower dehydration speeds to ensure uniform dehydration. Under the same absorbency level, easily tangled materials are designed with lower dehydration speeds, which can avoid insufficient dehydration in some areas after tangling and reduce fabric damage caused by tangling.

[0048] Optionally, in one implementation of this embodiment, as shown in FIG3, if the fabric type is a highly absorbent and easily tangled material, the frequency at which the fabric processing cylinder alternately rotates forward and backward is higher than a preset frequency.

[0049] In this embodiment, the highly absorbent fabric exhibits increased fiber adhesion after absorbing water, making it prone to rapid twisting and tangling. For example, in down jackets, high-frequency forward and reverse rotation can switch the direction of force in time before the winding solidifies, reducing the time it takes for the fabric fibers to form a stable entangled structure and effectively dispersing the stress and contact state of the fabric. High-frequency direction switching can cause the fabric inside the tube to continuously tumble and misalign, avoiding prolonged compression and entanglement of local fabrics, while also reducing friction and adhesion between fibers, thus lowering the probability of entanglement.

[0050] This control can effectively alleviate the problem of increased entanglement caused by high water absorption. As the weight of highly absorbent fabrics increases, they become more difficult to untangle after entanglement. The impact force of high-frequency forward and reverse rotation can help to break up the initial entanglement, prevent the entanglement from deepening, and reduce the risk of fabric deformation and wear.

[0051] Optionally, in one implementation of this embodiment, as shown in FIG3, the duration of the eighth rotation speed dehydration is less than a preset duration, or the eighth rotation speed is equal to zero.

[0052] In this embodiment, when the fabric type is a low-absorbency, non-tangling material, the eighth rotation speed can be designed to be very small or even zero, achieving a state of no dehydration, thereby ensuring the safety of the low-absorbency, non-tangling fabric and avoiding excessive wrinkling or other damage to the fabric caused by dehydration.

[0053] Example 3 This example provides an electronic device, including a memory and a processor. The memory is used to store computer instructions, and the processor is used to call and execute the computer instructions to implement the fabric material determination method in Example 1, or to call and execute the computer instructions to implement the control method in Example 2.

[0054] In this embodiment, since the electronic device includes the fabric material determination method in Embodiment 1 or the control method in Embodiment 2, the electronic device has all the beneficial effects of the fabric material determination method in Embodiment 1 or the control method in Embodiment 2, which will not be elaborated further.

[0055] Example 4 This example provides a fabric processing device that performs fabric material determination using the fabric material determination method in Example 1, or performs the control method in Example 2, or includes the electronic equipment in Example 3.

[0056] In this embodiment, since the fabric processing equipment executes the fabric material determination method in Embodiment 1, the control method in Embodiment 2, or includes the electronic equipment in Embodiment 3, the fabric processing equipment has all the beneficial effects of the fabric material determination method in Embodiment 1, the control method in Embodiment 2, or the electronic equipment in Embodiment 3, which will not be elaborated further.

[0057] In summary, the ingenious design of the fabric material identification method lies in the following: First, the method assesses the fabric's water absorption characteristics in the first stage. Second, it monitors the inner drum's mechanical response to determine the fabric's tangling tendency. After the initial assessment, a brief, diagnostic micro-cycle of gentle washing and low-speed spin-drying is introduced. During this process, the real-time load current fluctuations of the motor are monitored to analyze the fabric's dynamic behavior under mechanical action, verifying and refining the initial assessment results, ultimately confirming the material type. This phased approach, combining initial assessment with final confirmation, improves the accuracy of material identification. Based on the confirmed material type, the system automatically retrieves and sets the most suitable spin-drying parameters from a preset parameter library, without relying on manual user selection. It automatically adapts to different fabric combinations each time, and by analyzing the overall characteristics of the fabric, it provides a comprehensive and optimal washing solution for mixed-material fabric loads, improving the adaptability of mixed washing and avoiding fabric damage caused by improper program selection.

[0058] Second, in the first judgment stage, the fabric material inside the fabric treatment tube is judged. The method used in the first judgment stage to identify the fabric material can be through water absorption-related parameters such as the fabric's water absorption rate, saturated weight, and water absorption rate. The corresponding first judgment result is that the fabric has high water absorption characteristics or low water absorption characteristics. The first stage judgment can make a preliminary identification of the fabric material type, classifying the fabric into high water absorption characteristics and low water absorption characteristics, providing basic data for the second stage judgment. Moreover, the classification of fabrics into high and low water absorption characteristics based on water absorption characteristics is simpler and more direct, avoiding problems such as misjudgment caused by multiple types of material identification.

[0059] Third, in the second judgment stage, during the brief dehydration process of the fabric treatment drum, the magnitude of the motor current fluctuation is monitored, and the second judgment result is divided into fabrics that are easy to entangle and fabrics that are not easy to entangle. It is easier to determine the most prominent characteristics of the final fabric material based on the first judgment result and the second judgment result. This is not only accurate, but the final judgment result is also more targeted, making it easier for the fabric treatment equipment to adopt targeted washing mode, dehydration mode, drying mode and care mode according to the judgment result.

[0060] Fourth, based on the first and second judgment results, the final fabric material is determined, including four categories: highly absorbent and easily tangled materials, highly absorbent and non-tangled materials, low absorbent and easily tangled materials, and low absorbent and non-tangled materials. The washing and spin-drying modes for these four material categories differ, achieving targeted washing and spin-drying for each category. In the washing modes, high-absorbency materials are matched with high spin speeds to ensure cleaning power. High-absorbency fabrics become heavier and have stronger stain adhesion after absorbing water, so the third and first spin speeds are relatively high, providing sufficient washing impact to avoid stain residue. Low-absorbency materials are matched with relatively low spin speeds, balancing cleaning and protection. Stains on low-absorbency fabrics are easily removed, and the fifth and seventh spin speeds are set to complete cleaning while avoiding excessive pulling and damage to thin, non-absorbent fabrics caused by high spin speeds. Easily tangled materials require relatively lower spin speeds to reduce tangling damage and unnecessary slowdowns in washing efficiency. For the same absorbency rating, designing lower spin speeds for the washing modes corresponding to easily tangled materials effectively reduces fiber entanglement, preventing fabric deformation or wear, and avoiding slowing down the washing process due to tangling. In the spin-drying mode, high-absorbency materials are matched with high spin speeds to improve dehydration efficiency. High-absorbency fabrics contain more moisture, and the fourth and second spin speeds can quickly remove water, shortening drying time and saving energy. Low-absorbency materials use low spin speeds to reduce fabric wear. Low-absorbency fabrics contain less moisture, and the sixth and eighth spin speeds are sufficient for dehydration. Low spin speeds also reduce centrifugal force impact on the fabric, protecting the fiber structure. Easily tangled materials correspond to relatively lower spin-drying speeds to ensure uniform dehydration. For the same absorbency rating, the lower spin-drying speeds designed for easily tangled materials prevent insufficient dehydration in certain areas after tangling, while also reducing fabric damage caused by tangling.
