Abstract
Description
Technical Field
[0001] This invention relates to the field of fabric treatment methods, and in particular to a control method, electronic equipment, and fabric treatment equipment for a fabric treatment device. Background Technology
[0002] In the field of fabric processing methods, such as household top-loading washing machines, the drying function largely relies on the combination of heating elements and fans. However, its core tumbling mechanism still uses the traditional unidirectional rotation mode, causing the clothes to rotate periodically to achieve hot air penetration and moisture evaporation. This mode has significant drawbacks. Due to the lack of an active disturbance mechanism, fabrics tend to accumulate locally in the inner drum due to gravity and friction, leading to tangling, especially with small items or heavy fabrics. Furthermore, uneven tumbling of some fabrics, which remain at the bottom or against the walls of the drum for extended periods, prevents them from fully contacting the hot air, resulting in low drying efficiency. Summary of the Invention
[0003] The technical problem to be solved by the present invention is that the existing technology of pulsator washing machine has significant defects.

[0007] The larger the absolute value of the temperature difference between the bottom and the middle of the inner tub and / or the larger the absolute value of the humidity difference between the bottom and the middle of the inner tub, the shorter the preset interval time; conversely, the smaller the absolute value of the temperature difference between the bottom and the middle of the inner tub and / or the smaller the absolute value of the humidity difference between the bottom and the middle of the inner tub, the longer the preset interval time.
[0008] In some embodiments, the first preset duration is less than the second preset duration.
[0009] In some embodiments, the preset interval duration is t; ;
[0010] Wherein, ΔT is the temperature difference between the bottom and the middle of the inner tub, ΔR is the humidity difference between the bottom and the middle of the inner tub, and a, b, and c are adjustment coefficients, 0.1≤a≤0.15, 10≤b≤15, 30≤c≤50.

[0013] In some embodiments, it is determined whether the drying process has reached the dryness judgment condition. If the drying process has not reached the dryness judgment condition, the temperature and humidity at the bottom of the inner drum and the temperature and humidity at the middle are obtained. The preset interval time t is calculated, and the electromagnetic clutch is energized for a first preset time. After the preset interval time t, the electromagnetic clutch is de-energized for a second preset time.

The electromagnetic clutch is connected to the output shaft in a transmission manner, and the driven member is in clearance fit with the output shaft. When the electromagnetic clutch is energized, it generates a magnetic force to attract the driven member to slide along the output shaft axial direction until it engages with the electromagnetic clutch.

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.
[0036] Top-loading washing machines rely heavily on heating elements and fans for their drying function, but their core tumbling mechanism still uses a traditional unidirectional rotation mode, causing clothes to rotate periodically to allow hot air to penetrate and moisture to evaporate. However, this mode has significant drawbacks. Due to the lack of an active disturbance mechanism, fabrics tend to accumulate locally in the drum due to gravity and friction, making them prone to tangling, especially with small items or heavy fabrics. Furthermore, because some fabrics tumble unevenly and remain at the bottom or against the drum walls for extended periods, they don't get sufficient contact with hot air, resulting in low drying efficiency.
[0037] Based on this, the following embodiments are proposed.
[0038] Example 1:
[0039] like Figure 3 As shown, this embodiment provides a control method for a fabric processing device. The fabric processing device includes an inner drum 1, a pulsator 3, an electromagnetic clutch 6, and a drive motor 5. The pulsator 3 is disposed inside the inner drum 1. The drive motor 5 is connected to the inner drum 1 through the electromagnetic clutch 6, and the drive motor 5 establishes / disconnects the transmission connection with the pulsator 3 by turning the electromagnetic clutch 6 on / off.
[0040] The control method includes: during the drying process of the fabric processing equipment, controlling the drive motor 5 to drive the inner drum 1 to rotate in one direction, and controlling the electromagnetic clutch 6 to alternately turn on and off power to drive the impeller 3 to start and stop operation.
[0041] The control of the electromagnetic clutch 6 to alternately turn on / off includes: controlling the electromagnetic clutch 6 to be energized for a first preset duration, and after a preset interval, controlling the electromagnetic clutch 6 to be de-energized for a second preset duration, and so on, in an alternating cycle.
[0042] The larger the absolute value of the temperature difference between the bottom and the middle of the inner tub 1 and / or the larger the absolute value of the humidity difference between the bottom and the middle of the inner tub 1, the shorter the preset interval time; conversely, the smaller the absolute value of the temperature difference between the bottom and the middle of the inner tub 1 and / or the smaller the absolute value of the humidity difference between the bottom and the middle of the inner tub 1, the longer the preset interval time.
[0043] In this embodiment, the fabric handling device is a pulsator-type washing machine. When the user triggers the drying function, the fabric handling device receives the drying signal and then enters the preset drying process. At this time, the drive motor 5 starts and drives the inner tub 1 to rotate in the same direction according to the set operating parameters. This rotation in the same direction is a continuous low-speed rotation, the purpose of which is to drive the fabric in the inner tub 1 to tumble as a whole, avoiding the fabric from sitting still and piling up for a long time. At the same time, the electromagnetic clutch 6 alternately performs power-on and power-off operations according to specific control logic. Through this alternating switching, the transmission connection between the pulsator 3 and the drive motor 5 is established and disconnected, thereby causing the pulsator 3 to produce intermittent movement, forming an active disturbance on the fabric, solving the problems of easy tangling and uneven heating of fabric in the traditional drying process.
[0044] During the drying process, the unidirectional rotation of the inner drum 1 provides macroscopic tumbling force to the fabric, allowing it to be continuously lifted and dropped within a certain range, initially loosening the fabric. Meanwhile, the alternating on / off energization of the electromagnetic clutch 6 provides intermittent drive to the impeller 3. When the electromagnetic clutch 6 is energized, the impeller 3 receives power from the drive motor 5 and rotates, specifically loosening and agitating fabrics piled at the bottom or tangled together. When the electromagnetic clutch 6 is de-energized, the transmission connection between the impeller 3 and the drive motor 5 is disconnected, and the impeller 3 moves or slides slightly under the influence of the fabric, avoiding excessive agitation that could damage the fabric. This combination of continuous rotation of the inner drum 1 and intermittent movement of the impeller 3 forms a composite motion mechanism of "macroscopic tumbling + microscopic agitation," effectively increasing the contact area between the fabric and the hot air, accelerating moisture evaporation, improving drying efficiency, and reducing fabric tangling.
[0045] By precisely controlling the electromagnetic clutch 6 in this fabric processing equipment, the inner drum 1 and the impeller 3 achieve coordinated movement during the drying process, enabling the inner drum 1 and the impeller 3 to rotate in various modes, either independently or in combination. This control method improves fabric drying performance by optimizing the control logic of the existing electromagnetic clutch 6 without requiring additional drive devices. It features a simple structure, low modification cost, and strong applicability, and can be widely applied to various similar impeller 3-type fabric processing equipment.
[0046] like Figure 3As shown, in one implementation of this embodiment, controlling the electromagnetic clutch 6 to alternately turn on / off includes:
[0047] The electromagnetic clutch 6 is energized for a first preset duration, and after a preset interval, the electromagnetic clutch 6 is de-energized for a second preset duration, and this process is repeated alternately.
[0048] In this embodiment, the first preset duration is the time during which the electromagnetic clutch 6 remains energized. During this period, the impeller 3 establishes a transmission connection with the drive motor 5 and rotates, which agitates and disperses the fabric. The preset interval duration is the transition time between the electromagnetic clutch 6 being energized and de-energized, ensuring a smooth disconnection of the transmission connection and avoiding mechanical impact. The second preset duration is the time during which the electromagnetic clutch 6 remains de-energized. At this time, the impeller 3 is in a follow-up state, and the fabric continues to tumble and loosen under the drive of the inner tub 1.
[0049] When the fabric processing equipment enters the drying process, the drive motor 5 drives the inner drum 1 to rotate continuously in the same direction. Simultaneously, the control system, according to set parameters, first energizes the electromagnetic clutch 6 and maintains it for a first preset time. The impeller 3 rotates under the drive motor 5, agitating the fabric. After the first preset time, the control system de-energizes the electromagnetic clutch 6, entering a preset interval period. At this time, the magnetic force of the electromagnetic clutch 6 gradually disappears, and the transmission connection between the impeller 3 and the drive motor 5 gradually disconnects. After the preset interval period, the electromagnetic clutch 6 remains de-energized for a second preset time. The impeller 3 moves with the fabric and the inner drum 1, further loosening the fabric under continuous rotation. After the second preset time, the control system energizes the electromagnetic clutch 6 again, entering the next "energize-interval-de-energize" cycle, repeating this process until the drying process ends. This timed cyclical control method ensures that the agitation of the impeller 3 is regular and stable, guaranteeing effective agitation of the fabric while avoiding excessive wear or entanglement of the fabric caused by prolonged continuous rotation of the impeller 3. The values of the first preset time, the preset interval time, and the second preset time can be flexibly adjusted according to factors such as the material, weight, and humidity of the fabric to adapt to the drying needs of different types of fabrics and improve the adaptability and intelligence of the drying process. For example, for thick, easily tangled fabrics, the first preset time can be appropriately extended to enhance the agitation effect; for thin, easily damaged fabrics, the first preset time can be shortened to reduce the agitation intensity, thereby maximizing the protection of the fabric while ensuring the drying effect.
[0050] In one embodiment, the first preset duration is set to 0.8 seconds, the preset interval duration is set to 30 seconds, and the second preset duration is set to 60 seconds. When the fabric processing equipment enters the drying process, the inner drum 1 continuously rotates in the same direction at a preset speed. The control system first energizes the electromagnetic clutch 6 for 0.8 seconds, causing the impeller 3 to rotate rapidly under the drive motor 5, briefly and forcefully dispersing the fabric piled at the bottom of the drum, breaking the tendency for the fabric to entangle. After 0.8 seconds of energization, the electromagnetic clutch 6 is de-energized, entering a 30-second preset interval. The transmission connection between the impeller 3 and the drive motor 5 is smoothly disconnected, and the impeller 3 moves with the fabric. After the 30-second interval, the electromagnetic clutch 6 remains de-energized for 60 seconds. During this period, the fabric is fully tumbled under the continuous rotation of the inner drum 1, making full contact with the hot air, and moisture evaporates continuously. After 60 seconds, the control system energizes the electromagnetic clutch 6 again for 0.8 seconds to enter the next cycle. This parameter setting is suitable for medium-weight cotton fabrics, effectively preventing entanglement while ensuring drying efficiency.
[0051] In another embodiment, the first preset duration is set to 0.3 seconds, the preset interval duration is set to 20 seconds, and the second preset duration is set to 80 seconds. For delicate fabrics such as silk and synthetic fibers, which are easily damaged, the shorter first preset duration reduces the intensity of the agitation of the fabric by the impeller 3, preventing damage to the fabric fibers; the 20-second preset interval duration allows for quick switching of the transmission connection, reducing the impact on the fabric during the transition; and the 80-second second preset duration provides sufficient time for the fabric to tumble and loosen, ensuring full contact between the fabric and the hot air for gentle drying. Under these parameter settings, the agitation action of the impeller 3 is gentle and the intervals are long, which can prevent the fabric from tangling, protect the soft texture and appearance of the fabric, and improve the user experience.
[0052] By setting the first preset duration, the preset interval duration, and the second preset duration, the fabric processing equipment can accurately control the motion state of the impeller 3, making the agitation action of the impeller 3 regular and stable. This ensures effective disturbance of the fabric while avoiding excessive wear or entanglement of the fabric caused by the impeller 3 rotating continuously for a long time.
[0053] In this embodiment, during the drying process, temperature and humidity sensors are respectively installed at the bottom and middle of the inner drum 1 to collect the temperature and humidity values of the bottom and middle sections in real time. The temperature difference ΔT and humidity difference ΔR are calculated, enabling real-time sensing and response to the fabric drying status. The absolute values of ΔT and ΔR reflect the fabric stacking and drying uniformity. For example, when the fabric is stacked at the bottom of the inner drum 1, the stacked area has a larger fabric thickness and a relatively higher moisture content. This results in the temperature at the bottom of the fabric being much lower than the temperature in the middle, making the absolute value of ΔT larger. At the same time, the humidity in the middle of the fabric is much lower than the humidity at the bottom, making the absolute value of ΔR larger. When the sensors detect an increase in the absolute values of ΔT and ΔR, the control system determines that the fabric is in a stacked state. Therefore, it automatically shortens the preset interval time, increases the agitation frequency of the impeller 3, and promptly disperses the stacked fabric to avoid insufficient drying in certain areas. When the fabric is uniformly loose, the temperature and humidity difference between the bottom and the middle is small, resulting in smaller absolute values of ΔT and ΔR. The control system determines that the fabric is in a uniformly loose state and automatically extends the preset interval time, reducing the number of agitations of the impeller 3, thus lowering energy consumption and fabric wear, and improving drying efficiency. By dynamically adjusting the preset interval time in relation to the absolute values of the temperature and humidity differences between the bottom and the middle of the inner drum 1, the system can shorten the impeller start-stop time in a timely manner according to drying needs, increasing the agitation frequency of the impeller on the clothes and providing a better drying environment. At the same time, it can extend the impeller start-stop time when the clothes are about to finish drying, reducing the agitation frequency of the impeller on the clothes, saving energy while avoiding damage to the clothes from excessive agitation.
[0054] Optionally, such as Figure 4 As shown, in one implementation of this embodiment, the first preset duration is less than the second preset duration.
[0055] In this embodiment, the main purpose of the control method is to control the inner tub 1 to loosen and spread the fabric so that the moisture in the fabric can evaporate quickly, and to use the impeller 3 to help agitate the fabric and prevent the fabric from tangling together.
[0056] In the initial stage of the drying process, the fabric has a high moisture content and is prone to tangling. The purpose of this control method to control the inner drum 1 to rotate continuously in the same direction is to drive the fabric to tumble continuously, so that all surfaces of the fabric are evenly heated and fully contacted with the hot air. This process takes a long time to achieve, so the second preset time is set to be relatively long. In this way, after the electromagnetic clutch 6 is de-energized, the impeller 3 rotates together with the inner drum 1 in a single direction for a long time without power, ensuring that the fabric has enough time to tumble as a whole, improving the uniformity of contact between the fabric and the hot air, accelerating the evaporation rate of the fabric moisture, and improving the drying efficiency of the fabric processing equipment. The first preset time is set relatively short because the main function of the impeller 3 is to intermittently loosen or pile up tangled or accumulated fabric, preventing it from tangling and piling up during the unwinding process. This operation is used to assist the fabric in unwinding better. Therefore, when the electromagnetic clutch 6 is energized, the impeller 3 rotates in the opposite direction to the inner drum 1 for a short time. This allows the fabric to remain loose overall, and the more precise and gentle force generated by the intermittent, brief agitation can untangle the tangled parts of the fabric. The brief agitation also reduces frictional damage between the impeller 3 and the fabric, which is especially suitable for fragile and easily damaged fabrics, preventing the fabric from knotting or damaging the fibers due to prolonged friction. In the middle and later stages of the drying process, the fabric has less moisture and the tendency to tangle weakens. The longer unwinding operation allows the fabric to dry thoroughly, improving the overall stability and reliability of the drying process.
[0057] In one embodiment, the first preset duration is set to 0.5 seconds, and the second preset duration is set to 70 seconds. In the initial stage of the drying process, the fabric is highly moist and heavy, and it is easy for it to accumulate and entangle at the bottom of the inner drum 1. At this time, every 70 seconds, the impeller 3 performs a brief agitation for 0.5 seconds, which can quickly break up the entangled parts of the fabric and restore the fabric to a loose state. Since the first preset duration is only 0.5 seconds, the agitation intensity is moderate and will not cause excessive friction on the fabric. At the same time, the second preset duration of 70 seconds ensures that the fabric has enough time to tumble under the action of the inner drum 1 and fully contact the hot air to accelerate the evaporation of moisture.
[0058] In another embodiment, the first preset duration is set to 0.7 seconds, and the second preset duration is set to 90 seconds. For heavier fabrics such as cotton clothing and towels, which tend to entangle more easily, a 0.7-second agitation time provides a relatively long force to loosen the heavier fabrics. The 90-second second preset duration provides these thick fabrics with a longer tumbling time to come into contact with the hot air, ensuring that the moisture inside the fabric gradually penetrates to the surface and is carried away by the hot air. This longer duration satisfies the agitation intensity required for thick fabrics while ensuring uniform drying through a longer loosening time. This avoids the negative situation of localized dryness and dampness in thick fabrics after drying, ensuring that even thick fabrics achieve good drying results.
[0059] By setting the first preset time to be less than the second preset time, it can ensure that the fabric is fully loosened to allow a larger area to come into contact with the hot air, while preventing the fabric from tangling together through moderate agitation. At the same time, it can also avoid the negative impact of excessive agitation on the fabric material, thus balancing the drying efficiency of the fabric and the protection of the fabric material.
[0060] Optionally, such as Figure 4 As shown, in one implementation of this embodiment, the preset interval duration is t; t=-a|ΔT|-b|ΔR|+c; where ΔT is the temperature difference between the bottom and middle of the inner tub 1, ΔR is the humidity difference between the bottom and middle of the inner tub 1, and a, b, and c are all adjustment coefficients, 0.1≤a≤0.15, 10≤b≤15, 30≤c≤50.
[0061] In this embodiment, 0℃≤ΔT≤100℃, 0%≤ΔR≤100%, during the drying process, temperature and humidity sensors are respectively installed at the bottom and middle of the inner drum 1 to collect the temperature and humidity values at the bottom and middle in real time, and calculate the temperature difference ΔT and humidity difference ΔR. This enables real-time sensing and response to the drying status of the fabric. The magnitudes of ΔT and ΔR can reflect the fabric accumulation and drying uniformity. The adjustment coefficient c is the base interval time to ensure that the fabric is in an ideal uniform state. That is, when ΔT and ΔR are 0, the preset interval time can still be maintained within a reasonable range, thereby ensuring the stability of the drying process. The specific working principle is as follows:
[0062] When the fabric accumulates at the bottom of the inner drum 1, the accumulated area has a greater fabric thickness and a relatively higher moisture content. This results in the temperature at the bottom of the fabric being much lower than the temperature in the middle, leading to a larger absolute value of ΔT. Simultaneously, the humidity in the middle of the fabric is much lower than the humidity at the bottom, resulting in a larger absolute value of ΔR. When the sensors detect an increase in the absolute values of ΔT and ΔR, the control system determines that the fabric is in a state of accumulation. It then automatically shortens the preset interval time, increasing the agitation frequency of the impeller 3 to promptly disperse the accumulated fabric and prevent incomplete drying in certain areas.
[0063] When the fabric is uniformly loose, the temperature and humidity difference between the bottom and the middle is small, therefore the absolute values of ΔT and ΔR are also small. In the formula for calculating the preset interval time t, t = -a|ΔT| - b|ΔR| + c, a and b are both positive numbers. When the absolute values of ΔT and ΔR increase, the value of t decreases, meaning the preset interval time is shortened; when the absolute values of ΔT and ΔR decrease, the value of t increases, meaning the preset interval time is extended. When the sensor detects a decrease in the absolute values of ΔT and ΔR, the control system determines that the fabric is in a uniformly loose state, and automatically extends the preset interval time, reducing the number of agitations by the impeller 3, lowering energy consumption and fabric wear, and improving drying efficiency.
[0064] The range of values for adjustment coefficients a, b, and c can adapt to the drying needs of different types of fabrics and different initial humidity conditions, allowing users to fine-tune the coefficient values according to the actual usage scenario, thus enhancing the flexibility and adaptability of the control method. In addition, the calculation logic can be implemented in the control system through programming without complex hardware upgrades, making it highly practical and operable.
[0065] In one embodiment, the adjustment coefficients are set to a=0.1, b=10, and c=50, respectively. In the initial stage of the drying process, assuming the sensor detects ΔT=-5 degrees Celsius (i.e., the bottom temperature is 5 degrees Celsius lower than the middle temperature) and ΔR=15% relative humidity (i.e., the bottom humidity is 15% higher than the middle humidity), then |ΔT|=5 and |ΔR|=0.15. This indicates that the fabric is currently in a piled-up state and requires untangling. Substituting |ΔT|=5 and |ΔR|=0.15 into the formula, we get t=-0.1×5-10×0.15+50=-0.5-1.5+50=48 seconds. The preset interval should be set to 48 seconds. The impeller 3 agitates the fabric every 48 seconds to untangle it. In the middle and later stages of the drying process, assuming the sensor detects ΔT = -2 degrees Celsius and ΔR = 6% relative humidity, the fabric is in a loose and unfolded state. Substituting ΔT = -2 degrees Celsius and ΔR = 6% relative humidity into the formula, we get t = -0.1 × 2 - 10 × 0.06 + 50 = -0.2 - 0.6 + 50 = 49.2 seconds. Therefore, the preset interval should be extended to 49.2 seconds to reduce the number of agitations and thus reduce the energy consumption of the fabric processing equipment.
[0066] This control method introduces adjustment coefficients a, b, and c, and obtains the real-time preset interval duration based on the real-time temperature and humidity difference between the bottom and middle of the inner drum 1. This allows the preset interval duration to be continuously and dynamically adjusted according to the actual drying state of the fabric, thereby achieving precise dynamic control of the fabric during the drying process and improving the intelligence level of the fabric processing equipment.
[0067] Optionally, such as Figure 4 As shown, in one implementation of this embodiment, the preset interval duration is t0, where 20s≤t0≤40s.
[0068] In this embodiment, the preset interval duration t0 is fixed between 20 and 40 seconds, which is suitable for scenarios where the requirements for drying control logic are relatively simple or where there is no need to dynamically adjust according to the fabric state. This makes the fabric processing equipment more convenient to operate and more stable when executing the control method, and can meet the drying needs of most conventional fabrics. Users can select a suitable t0 value between 20 and 40 seconds according to their own usage habits and fabric type.
[0069] During the drying process, the drive motor 5 drives the inner drum 1 to rotate continuously in the same direction. The electromagnetic clutch 6 alternately switches on and off according to a fixed cycle of "first preset energization time - interval t0 seconds - second preset de-energization time". This control logic is relatively simple, requiring no additional temperature and humidity sensors or complex algorithm calculations, thus reducing the requirements for hardware costs and control system complexity. It is suitable for relatively simple and economical fabric processing equipment, making the application scenarios of this control method more extensive. The preset interval t0 is limited to the range of 20 to 40 seconds. This range is suitable for the drying needs of most conventional fabrics such as cotton, chemical fibers, and blends, and achieves a good balance between ensuring the loosening effect of the fabric and the agitation frequency. The lower limit of 20 seconds ensures that the agitation interval of the impeller 3 is not too short, avoiding fabric wear or excessive energy consumption of the fabric processing equipment due to frequent agitation. The upper limit of 40 seconds ensures that the single agitation interval of the impeller 3 is not too long, thereby timely breaking the entanglement tendency of the fabric and preventing the fabric from tangling and piling up.
[0070] In one embodiment, the preset interval t0 is set to 25 seconds, making it suitable for small, easily tangled fabrics such as underwear, socks, and handkerchiefs. These fabrics are small and lightweight, and are very prone to tangling or sticking to the inner wall of the inner drum 1 during the drying process. The short interval of 25 seconds allows the impeller 3 to frequently agitate, breaking up the tangles in time, ensuring that each small fabric is fully loosened and exposed to hot air, avoiding incomplete drying in certain areas. At the same time, the short interval will not cause significant wear and tear on the small fabrics, balancing drying effect and fabric protection.
[0071] In another embodiment, the preset interval t0 is set to 35 seconds, making it suitable for medium to large-sized, non-tangling, heavy fabrics such as coats, trousers, and bed sheets. These fabrics are large in volume and relatively heavy. Driven by the continuous rotation of the inner drum 1, the fabric itself has strong tumbling ability and a relatively weak tendency to tangle. The 35-second interval provides sufficient time for the fabric to tumble and loosen, allowing the fabric surface to be heated evenly. At the same time, the longer interval also reduces the number of agitations of the impeller 3, reducing the energy consumption of the fabric processing equipment and reducing the friction between the impeller 3 and the fabric, thus achieving a good balance between preventing fabric tangling and improving fabric drying efficiency.
[0072] By fixing the preset interval t0 between 20 and 40 seconds, the agitation frequency of the impeller 3 can be effectively prevented from tangling the fabric, and the fabric can have enough time to tumble and loosen, and fully contact with the hot air to achieve efficient drying. In addition, the fixed interval makes the control method more convenient to operate, enhances its applicability and practicality, and thus expands the application scenarios of the control method.
[0073] Optionally, such asFigure 3 As shown, in one implementation of this embodiment, controlling the drive motor 5 to start the inner tub 1 to rotate in the same direction includes: controlling the drive motor 5 to start the inner tub 1 to rotate in the same direction at a preset speed, wherein the preset speed is V, 30r / min≤V≤120r / min.
[0074] In this embodiment, during the drying process, the drive motor 5 starts at a preset speed V and maintains stable operation. Through the transmission connection between the electromagnetic clutch 6 and the inner drum 1, it drives the inner drum 1 to rotate continuously in the same direction at a speed of V. When the speed is below 30 rpm, the fabric cannot be effectively lifted and therefore tends to accumulate at the bottom of the inner drum 1, failing to fully contact the hot air and resulting in low drying efficiency. When the speed is above 120 rpm, the centrifugal force on the fabric is large, making it easy to adhere to the inner wall of the inner drum 1 and preventing effective tumbling. Excessive speed also increases the energy consumption of the fabric processing equipment and may aggravate friction between fabrics, causing wear. The speed range of 30 to 120 rpm is considered a medium-speed rotation, which ensures that the fabric is smoothly lifted to a certain height in the inner drum 1 and then slowly falls back to the bottom of the inner drum 1 under the action of gravity, achieving a gentle tumbling motion. This ensures that all parts of the fabric surface can fully contact the hot air, improving drying uniformity and avoiding localized dampness or dryness. The smooth tumbling motion reduces friction and collisions between fabrics, protecting the fabric material, especially suitable for fragile and pill-prone fabrics. Furthermore, the low-speed rotation consumes less energy, meeting energy conservation and environmental protection requirements, while also reducing the load on the drive motor and transmission mechanism, extending the equipment's lifespan. Users can independently select a suitable preset speed V within the range of 30 to 120 revolutions per minute according to the type and weight of the fabric, making the fabric drying operation of the fabric processing equipment more flexible and further improving its adaptability.
[0075] In one embodiment, the preset rotation speed V is set to 35 revolutions per minute, suitable for thin and delicate fabrics such as silk, wool, and lace. These fabrics are soft and have low strength; excessively high rotation speeds can easily cause stretching, deformation, or fiber damage. The medium-speed rotation of 35 revolutions per minute allows for gentle tumbling, reducing friction and collisions between fabrics and maximizing the protection of their appearance and texture. Simultaneously, the low-speed rotation allows the fabric to fall slowly, avoiding tangling caused by high-speed drops, ensuring that every part of the fabric is evenly exposed to the hot air, achieving gentle drying and improving the user experience.
[0076] In another embodiment, the preset rotation speed V is set to 55 revolutions per minute, suitable for thick, sturdy fabrics such as denim, thick coats, and cotton quilts. These fabrics are heavy and highly absorbent, requiring strong tumbling force to achieve sufficient loosening. A rotation speed of 55 revolutions per minute provides sufficient centrifugal force to lift these heavy fabrics to a high height before they fall, breaking down the moisture binding inside the fabric by enhancing the tumbling intensity and accelerating the evaporation rate. At the same time, 55 revolutions per minute is still within the medium speed range, so it will not cause excessive wear to the thick fabrics and can also effectively prevent the fabric from piling up at the bottom of the inner drum 1, ensuring sufficient contact between the fabric and the hot air, thereby improving drying efficiency and shortening drying time.
[0077] By setting the preset rotation speed V within the range of 30 rpm to 120 rpm, the fabric can be tumbled smoothly and fully, while avoiding negative effects such as insufficient drying or severe wear caused by excessively high or low rotation speeds, thus further improving the adaptability of the fabric processing equipment.
[0078] Optionally, such as Figure 4 As shown, in one implementation of this embodiment, it is determined whether the drying process has reached the dryness judgment condition. If the drying process has not reached the dryness judgment condition, the temperature and humidity at the bottom of the inner drum 1 and the temperature and humidity at the middle are obtained, the preset interval time t is calculated, the electromagnetic clutch 6 is energized for a first preset time, and after the preset interval time t, the electromagnetic clutch 6 is de-energized for a second preset time. This process is repeated alternately until the drying process reaches the dryness judgment condition, and then the drive motor 5 is controlled to stop working to end the drying process.
[0079] In this embodiment, during the drying process, temperature and humidity sensors at the bottom and middle of the inner drum 1 continuously collect temperature and humidity data, respectively, and calculate in real time the difference between the bottom temperature and the middle temperature ΔT and the difference between the bottom humidity and the middle humidity ΔR.
[0080] When determining the dryness of fabrics, relying solely on humidity may be affected by ambient humidity, while relying solely on temperature may be affected by temperature fluctuations of the heating element. In this embodiment, the dryness determination condition is: the absolute value of ΔT is less than a preset temperature difference threshold, and the absolute value of ΔR is less than a preset humidity difference threshold.
[0081] When the absolute values of ΔT and ΔR are both less than their corresponding thresholds, it indicates that the fabric is evenly distributed in inner drum 1, and its moisture content has dropped to the preset standard for the fabric's dry state. At this point, the fabric has met the dryness judgment condition. Conversely, if the absolute values are greater than or equal to these thresholds, the fabric has not yet met the dryness judgment condition. The dryness judgment condition is set based on the actual drying state of the fabric, rather than a fixed drying time. This accurately reflects the degree of dryness of the fabric. The dryness judgment condition is a preset standard based on the state of the fabric when it is completely dry, avoiding the problems of "the time is up but the fabric is not completely dry" or "the fabric is completely dry but is still being dried" caused by a fixed time setting, thus improving the drying effect and user experience.
[0082] When the control system determines that the fabric has not yet reached the drying condition, it continues to control the electromagnetic clutch 6 to alternately turn on and off according to the cycle of first turning on the power for a first preset time, then at a preset interval t, and finally turning off the power for a second preset time. The drive motor 5 continuously drives the inner drum 1 to rotate in the same direction, maintaining the drying process until the fabric is determined to have reached the drying condition. At this time, the control system will issue a command to control the drive motor 5 to stop working and simultaneously turn off the power to the electromagnetic clutch 6, thus completely ending the drying process.
[0083] In one embodiment, the preset temperature difference threshold is set to 2 degrees Celsius, and the preset humidity difference threshold is set to 5% relative humidity. Assuming that after 30 minutes of drying, the sensor detects ΔT = 1.5 degrees Celsius and ΔR = 3% relative humidity, the fabric meets the drying criteria, and the control system stops the drive motor 5, ending the drying process. These threshold values are suitable for most conventional fabrics, ensuring complete drying without over-drying to prevent deformation or hardening, thus balancing drying efficiency with fabric material protection.
[0084] By real-time detection of the temperature difference ΔT and humidity difference ΔR between the bottom and middle of the inner drum 1, it is determined whether the fabric has reached the drying standard. This improves the accuracy of fabric drying judgment, avoids errors that may be caused by judging a single parameter, and enables the fabric processing equipment to automatically terminate the drying process when the conditions are met. This avoids the occurrence of fabric deformation, discoloration, fiber aging, etc. that may be caused by high temperature and long-term drying, as well as the situation of insufficient drying of fabric. It also avoids unnecessary energy consumption of the fabric processing equipment, thereby improving the intelligence and control accuracy of the control method in the drying process.
[0085] Optionally, in one implementation of this embodiment, multiple inner tubs 1, multiple impellers 3, and multiple electromagnetic clutches 6 are provided, and the multiple impellers 3 correspond one-to-one with the multiple inner tubs 1, and the multiple electromagnetic clutches 6 correspond one-to-one with the multiple impellers 3; the impellers 3 are disposed in the corresponding inner tubs 1, the drive motor 5 is connected to the corresponding inner tub 1 through the electromagnetic clutches 6, and the drive motor 5 establishes / disconnects the transmission connection with the corresponding impeller 3 by turning the electromagnetic clutches 6 on / off;
[0086] The control method further includes: during the drying process, the fabric processing equipment controls the drive motor 5 to drive multiple inner drums 1 to rotate in one direction, controls multiple electromagnetic clutches 6 to be energized at different times, and drives multiple impellers 3 to start at different times.
[0087] In this embodiment, preferably, controlling the staggered energization of the multiple electromagnetic clutches 6 to drive the staggered starting of the multiple impellers 3 includes: controlling one of any two electromagnetic clutches 6 to be energized and the other to be de-energized, driving the corresponding two impellers 3 to be running and the other to be stopped. By designing to control the staggered energization of the multiple electromagnetic clutches 6 to drive the staggered starting of the multiple impellers 3, only a single impeller is allowed to start or run. The instantaneous peak load of the motor only needs to match the starting load of a single impeller and the basic load of the unidirectional rotation of the inner barrel. The peak load is directly reduced to the single load level, thereby completely avoiding the overload risk of multiple load superposition and ensuring that the motor starts smoothly within the rated load range.
[0088] In this embodiment, during the drying process, the unidirectional rotation of the inner drum in the fabric treatment equipment can easily cause the fabric to adhere to the wall due to centrifugal force, forming a fixed clumping area. The moisture inside the clumping area cannot come into contact with the hot air, resulting in uneven drying with the outside dry and the inside wet. By staggering the power supply, multiple impellers operate alternately. The operating impellers, through the agitation of their blades, generate directional thrust on the fabric that is adhering to the wall or clumping, breaking the adhesion. Ultimately, the fabric forms a cycle of alternating tumbling, dispersing, and tumbling within the drum, ensuring that all fabrics can come into uniform contact with the hot air, completely solving the problem of incomplete drying in certain areas. Furthermore, when the impellers operate at staggered intervals, the agitation of a single impeller will create a local vortex within the drum, disturbing the hot air flowing over the fabric surface and preventing the formation of a static thermal boundary layer on the fabric surface. After the fabric is dispersed, the surface area increases significantly, allowing the hot air to fully penetrate into the gaps between the fabric fibers, accelerating the migration and evaporation of internal moisture to the surface. During the drying stage, the fabric has low moisture content and reduced fiber toughness. If multiple impellers operate simultaneously and forcefully, they will exert continuous squeezing and pulling forces on the fabric, causing fiber breakage or the formation of stubborn wrinkles. When the impellers are stationary, the fabric is prone to localized wear due to friction against the wall. Staggered power supply can make the stirring force of a single impeller more gentle, avoid the continuous impact force of the impellers, and solve the problem of excessive load on the drive motor.
[0089] Example 2
[0090] This embodiment provides an electronic device, including: a memory for storing computer instructions; and a processor for calling and executing the computer instructions to implement the control method in Embodiment 1.
[0091] In this embodiment, when the fabric processing equipment receives a drying signal, the processor first calls the initialization program for the drying process from the memory, starts the drive motor 5 to drive the inner drum 1 to rotate in the same direction at a preset speed V; simultaneously, the processor controls the electromagnetic clutch 6 to alternately turn on and off according to a preset cycle, and collects temperature and humidity data of the bottom and middle of the inner drum 1 in real time through temperature and humidity sensors, and calculates ΔT and ΔR; based on the values of ΔT and ΔR, the processor adjusts the preset interval time according to the calculation formula for dynamically adjusting the preset interval time t in Embodiment 1, and determines whether the fabric has reached the dryness judgment condition. If the fabric has not reached the dryness judgment condition, the processor continues to execute the control logic of alternating on and off of the electromagnetic clutch 6; if the fabric has reached the dryness judgment condition, the processor outputs a control signal to stop the drive motor 5 and end the drying process.
[0092] Since the electronic device proposed in this embodiment is used to call and execute computer instructions to implement the control method in Embodiment 1, the electronic device in this embodiment has all the beneficial effects of the control method in Embodiment 1, and will not be described again.
[0093] Example 3
[0094] like Figures 1-2 As shown, this embodiment provides a fabric processing device that can execute the control method in Embodiment 1, or the fabric processing device includes the electronic equipment in Embodiment 2.
[0095] The fabric processing equipment in this embodiment includes the electronic equipment in Embodiment 2 and is capable of executing the control method in Embodiment 1.
[0096] When the fabric processing equipment starts the drying process, if the equipment integrates the electronic device described in Example 2, the electronic device, upon receiving the signal to start the drying process, will activate the drive motor 5 to drive the inner drum to rotate in the same direction at a preset speed V. Simultaneously, the electronic device controls the electromagnetic clutch 6 to alternately energize and de-energize, causing the impeller to rotate intermittently and agitate the fabric. Subsequently, temperature and humidity sensors collect real-time temperature and humidity parameters at the bottom and middle of the inner drum and transmit them to the electronic device. The electronic device dynamically adjusts the preset interval duration by calculating ΔT and ΔR and determines whether the fabric has reached the drying criteria. If the fabric has not reached the drying criteria, drying control continues; if the fabric has reached the drying criteria, the electronic device controls the drive motor 5 to stop working, and the drying process ends. If the fabric processing equipment does not integrate the electronic device described in Example 2, the equipment directly executes the control method of Example 1 through its own control system to achieve the above-described drying process.
[0097] Since the fabric processing device proposed in this embodiment can execute the control method in Embodiment 1, or integrates the electronic equipment in Embodiment 2, the fabric processing device in this embodiment has all the beneficial effects of the control method in Embodiment 1 and the electronic equipment in Embodiment 2, which will not be repeated here.
[0098] Optionally, such as Figures 1-2 As shown, in one implementation of this embodiment, a first drive shaft is provided at the center of the bottom wall outside the inner tub, and a second drive shaft 4 is provided at the center of the impeller. The first drive shaft is constructed as a hollow bushing, and the second drive shaft 4 extends through and out of the first drive shaft. An electromagnetic clutch 6 and a driven member 7 are provided on the output shaft 501 of the drive motor 5. The electromagnetic clutch 6 is connected to the output shaft 501, and the driven member 7 is in clearance fit with the output shaft 501. When the electromagnetic clutch 6 is energized, it generates a magnetic force that attracts the driven member 7 to slide axially along the output shaft 501 until it engages with the electromagnetic clutch 6. When the electromagnetic clutch 6 is de-energized, the driven member 7 slides back along the output shaft 501 and separates from the electromagnetic clutch 6. The electromagnetic clutch 6 is connected to the first drive shaft, and the driven member 7 is connected to the second drive shaft 4 through the transmission assembly 9. The transmission assembly 9 includes a transmission shaft 901, a first transmission gear 902 connected to the transmission shaft 901, and a second transmission gear 401 disposed on the second drive shaft 4. The driven member 7 is connected to the transmission shaft 901 through the first transmission belt 11, and the first transmission gear 902 meshes with the second transmission gear 401.
[0099] In this embodiment, a first drive shaft is installed at the center of the outer bottom wall of the inner tub via a fixed structure. The first drive shaft is designed as a hollow shaft, and the inner diameter of the hollow shaft is equal to the outer diameter of the second drive shaft 4, so that the second drive shaft 4 can pass through the first drive shaft and be installed inside the first drive shaft. One end of the second drive shaft 4 passes through the hollow cavity of the first drive shaft and continues to extend outward. The center of the impeller is fixedly connected to the end of the second drive shaft 4. The first drive shaft and the second drive shaft 4 together form a compact double-layer shaft system, which can optimize the internal space layout of the fabric processing equipment, reduce the occupation of the internal space of the fabric processing equipment, and also realize the coaxial rotation of the inner tub and the impeller, so as to ensure that the fabric processing equipment can maintain a stable state when the inner tub and the impeller rotate at the same time, and also reduce the noise caused by mechanical vibration.
[0100] The output shaft 501 of the drive motor 5 and the electromagnetic clutch 6 are fixedly installed using a key connection, preventing slippage during transmission and ensuring continuous and stable power output. The driven member 7 is mounted on the output shaft 501, with a certain gap between its inner circumferential wall and the outer circumferential wall of the output shaft 501, allowing the driven member 7 to reciprocate axially along the output shaft 501. Corresponding engagement structures are provided on the opposing end faces of the electromagnetic clutch 6 and the driven member 7. An elastic member 8 is installed between the electromagnetic clutch 6 and the driven member 7, always in a partially extended pre-compressed state, providing a continuous and rapid separation force to the driven member 7, enabling the impeller to respond quickly to power switching. When the electromagnetic clutch 6 is energized, the generated electromagnetic force is greater than the elastic force of the elastic element 8. Under the action of the electromagnetic force, the driven element 7 overcomes the elastic force and moves towards the electromagnetic clutch 6, engaging with it. When the power is de-energized, the driven element 7 quickly disengages from the electromagnetic clutch 6 under the action of the elastic force of the elastic element 8. This achieves a rapid and reliable switching of the transmission connection between the impeller and the drive motor 5, ensuring precise control of the intermittent agitation of the impeller by the fabric processing equipment, accelerating the impeller's response speed, and reducing the mechanical wear of related components. The electromagnetic clutch 6 can be connected to the first drive shaft via a transmission belt, and the driven element 7 can also drive the impeller to rotate via a transmission belt to the second drive shaft 4. The electromagnetic clutch 6 is connected to the first drive shaft via a second transmission belt 12. Both the first transmission belt 11 and the second transmission belt 12 are made of high-strength, wear-resistant materials to ensure the reliability and durability of power transmission.
[0101] The transmission component includes a transmission shaft 901 and a first transmission gear 902 fixedly mounted at its end. The transmission shaft 901 is fixed between the driven member 7 and the second drive shaft 4 via a bearing housing. A transmission wheel is integrally formed on the driven member 7, and the transmission wheel is connected to the transmission shaft 901 via a first transmission belt 11. At the end of the second drive shaft 4, a second transmission gear 401 is fixed. The number of teeth on the second transmission gear 401 matches the number of teeth on the first transmission gear 902, maintaining a reasonable transmission ratio between them. The transmission wheel and the transmission shaft 901 are connected by the first transmission belt 11. Power is transmitted through the friction of the transmission belt, which has a certain shock absorption effect, absorbing the impact force generated during power transmission and making the power transmission smoother. The first transmission gear 902 and the second transmission gear 401 are tightly meshed to achieve rigid power transmission, preventing slippage between the two gears and thus accurately transmitting power to the second drive shaft 4. The first transmission gear 902 is positioned between the transmission wheel and the second transmission gear 401, ensuring that the rotation direction of the impeller and the output shaft 501 is opposite, thus ensuring that the rotation direction of the impeller and the inner drum is always opposite. The transmission assembly 9, through a composite transmission method combining a transmission belt and gear meshing, achieves higher power transmission efficiency and better stability. It can accurately transmit the rotational power of the driven member 7 to the impeller, ensuring the agitation intensity and effect of the impeller. Simultaneously, the gear meshing transmission method can also change the power transmission direction, ensuring that the rotation direction of the impeller and the inner drum is always opposite, thereby further improving the loosening and unfolding effect on the fabric.
[0102] The electromagnetic clutch 6 includes a coil 601 and a magnetic yoke 602. The coil 601 and the magnetic yoke 602 cooperate to form a closed magnetic circuit. The magnetic field generated when the coil 601 is energized is conducted through the magnetic yoke 602. The coil 601 is clearance-fitted with the output shaft 501, and the magnetic yoke 602 is drive-connected to the output shaft 501. The coil 601 in the electromagnetic clutch 6 can be made of multiple strands of enameled wire tightly wound on a frame to form a ring coil structure. The magnetic yoke 602 is made of laminated silicon steel sheets with excellent magnetic permeability. After the coil 601 and the magnetic yoke 602 are assembled according to a specific structure, they form a closed magnetic circuit structure, ensuring that the magnetic field generated when the coil 601 is energized is concentrated inside the magnetic yoke 602 for conduction, effectively reducing magnetic field leakage, maximizing the concentration of magnetic field energy, and improving the attraction force of the electromagnetic clutch 6. The coil 601 is fitted outside the output shaft 501 of the drive motor 5, maintaining a uniform gap between it and the output shaft 501 to ensure that the output shaft 501 does not rub against the stationary coil 601 when rotating. The magnetic yoke 602 and the output shaft 501 are connected by a fixed transmission. For example, the magnetic yoke 602 is fixed to the output shaft 501 by a spline connection, so that the magnetic yoke 602 and the output shaft 501 will not slip when rotating synchronously, so that the power is sufficient and stable.
[0103] When coil 601 is energized, a strong magnetic field is generated. This magnetic field is conducted through the closed magnetic circuit formed by yoke 602, giving yoke 602 strong magnetism. Since yoke 602 rotates synchronously with output shaft 501, and driven member 7 is clearance-fitted to output shaft 501 and located on one side of yoke 602, driven member 7 is attracted by yoke 602 under the influence of the magnetic field. This causes it to overcome the elastic force of elastic member 8 and move towards yoke 602, becoming attracted to it. Subsequently, driven member 7 rotates together with yoke 602 and output shaft 501, thus transmitting power to subsequent transmission components. When coil 601 is de-energized, the magnetic field disappears, and the magnetism of yoke 602 also disappears. Driven member 7 separates from yoke 602 under the elastic force of elastic member 8, and power cannot be transmitted to impeller 3, leaving impeller 3 in a powerless state.
[0104] This method, which controls the generation and disappearance of the magnetic field by switching the coil 601 on and off, and thus controls the engagement and disengagement of the driven part 7, enables the electromagnetic clutch 6 to achieve efficient and precise switching of power transmission. This provides key power control assurance for the realization of different washing modes in the fabric processing equipment, and improves the control accuracy and operational stability of the equipment.
[0105] Through the compact double-layer shaft system formed by the first drive shaft and the second drive shaft 4, and the synergistic effect of the electromagnetic clutch 6 and the driven part 7's electromagnetic attraction and elastic separation, the fabric processing equipment can flexibly control the independent operation of the inner tub and the impeller. This ensures both the cleaning effect of the fabric processing equipment in the washing mode and the thorough loosening of the fabric during the drying process, significantly improving the washing and drying performance and adaptability of the fabric processing equipment. The mutual cooperation of the various components in the transmission assembly 9 forms a complete and reliable power transmission path, ensuring that the driven part 7 can accurately and efficiently transmit power to the second drive shaft 4 through the combination of transmission belt and gear meshing. The second transmission belt 12 between the electromagnetic clutch 6 and the first drive shaft also ensures the stability of the power transmission of the inner tub. This allows the fabric processing equipment to flexibly control the power switching of the impeller, enabling it to achieve different washing modes and drying processes for different fabrics, such as the inner tub operating alone or the inner tub and the impeller operating in synergy. Its performance has been further improved.
[0106] Optionally, such as Figures 1-2 As shown, in one implementation of this embodiment, multiple inner tubs 1, impellers 3, electromagnetic clutches 6, and driven members 7 are provided. The multiple impellers 3 correspond one-to-one with the multiple inner tubs 1, the multiple driven members 7 correspond one-to-one with the multiple electromagnetic clutches 6, the electromagnetic clutches 6 are connected to the corresponding first drive shaft 2, and the driven members 7 are connected to the corresponding second drive shaft 4.
[0107] In the fabric processing equipment of this embodiment, multiple inner drums 1, impellers 3, electromagnetic clutches 6, and driven components 7 are provided, and the number is consistent. Each impeller 3 corresponds one-to-one with an inner drum 1, and is precisely installed at the center of the bottom wall of the corresponding inner drum 1, ensuring that each inner drum 1 can independently achieve the drying function. The multiple driven components 7 also correspond one-to-one with the multiple electromagnetic clutches 6, and each driven component 7 cooperates with an electromagnetic clutch 6 to control the power transmission. Each electromagnetic clutch 6 establishes a transmission connection with the first drive shaft 2 on the corresponding inner drum 1 through an independent transmission structure, and each driven component 7 is also connected to the second drive shaft 4 on the corresponding impeller 3 through a corresponding transmission component, thereby realizing the independent control and operation of multiple inner drums 1 to meet the user's need to dry multiple types of fabrics simultaneously.
[0108] The fabric processing equipment has multiple inner drums, each containing a corresponding impeller. Each inner drum has a first drive shaft connected to an electromagnetic clutch 6, and each impeller has a second drive shaft 4 connected to a driven component 7. The driven components 7 and electromagnetic clutches 6 are matched one-to-one. The drive motors 5 can be a single main drive motor 5 providing power to the multiple electromagnetic clutches 6 via a distribution mechanism, or each electromagnetic clutch 6 can have its own independent drive motor 5. When the fabric in multiple inner drums needs to be dried simultaneously, the electronic equipment in the fabric processing equipment controls each electromagnetic clutch 6 to alternately energize and de-energize according to its corresponding control parameters. This causes each inner drum to rotate continuously in the same direction under the drive of its corresponding electromagnetic clutch 6. Consequently, each impeller intermittently agitates under the transmission of its corresponding driven component 7, achieving independent drying control for the multiple inner drums. When only some inner drums need to be dried, the electronic equipment only controls the electromagnetic clutch 6 and drive motor 5 of the corresponding inner drum to operate, while keeping the other inner drums stationary, thus saving overall energy consumption of the fabric processing equipment.
[0109] The control parameters for each inner drum can be set independently. Users can adjust the drying parameters for each drum based on factors such as the type, weight, and humidity of the fabrics inside, adapting to the drying needs of different types of fabrics. This improves the drying effect and protects the fabrics. Users can achieve personalized drying by setting parameters such as the first preset time, second preset time, preset rotation speed V, and drying condition threshold. For example, after placing heavy cotton clothing in one inner drum, a user can set a longer first preset time and a higher preset rotation speed for that drum; while placing light silk clothing in another inner drum, a user can set a shorter first preset time and a lower preset rotation speed for that drum, thus ensuring that different types of fabrics achieve the best drying results.
[0110] By incorporating multiple inner drums and impellers within the fabric processing equipment and controlling their independent or combined operation, the efficiency of processing multiple batches of different types of fabrics simultaneously is significantly improved. This saves time spent queuing for batches and enables personalized drying and washing control. It not only enhances the drying and material protection of fabrics but also allows for the separate washing of fabrics with different needs, improving ease of use and hygiene. This expands the application scenarios and scope of the fabric processing equipment.
[0111] In summary, the ingenious design of this control method lies in:
[0112] Firstly, through precise control of the electromagnetic clutch in this fabric processing equipment, the inner drum and the impeller achieve coordinated movement during the drying process, enabling the inner drum and impeller to rotate in various modes, either independently or in combination. This control method improves fabric drying performance by optimizing the control logic of the existing electromagnetic clutch without requiring additional drive devices. It features simple structure, low modification cost, and strong applicability, and can be widely applied to various similar impeller-type fabric processing equipment.
[0113] Secondly, by setting the first preset duration, the preset interval duration, and the second preset duration, the fabric processing equipment can accurately control the motion state of the impeller, making the agitation action of the impeller regular and stable. This ensures effective disturbance of the fabric while avoiding the problem of excessive wear or increased entanglement of the fabric caused by the impeller rotating continuously for a long time.
[0114] Third, by setting the first preset time to be less than the second preset time, it can ensure that the fabric is fully loosened to allow a larger area to come into contact with the hot air, while preventing the fabric from tangling together through moderate agitation. At the same time, it can also avoid the negative impact of excessive agitation on the fabric material, thus balancing the drying efficiency of the fabric and the protection of the fabric material.
[0115] Fourth, this control method introduces adjustment coefficients a, b, and c, and obtains the real-time preset interval duration based on the real-time temperature and humidity difference between the bottom and middle of the inner drum. This allows the preset interval duration to be continuously and dynamically adjusted according to the actual drying state of the fabric, achieving precise dynamic control during the fabric drying process and thus improving the intelligence level of the fabric processing equipment.
[0116] Fifth, by fixing the preset interval t0 between 20 and 40 seconds, the agitation frequency of the impeller can be effectively prevented from tangling the fabric, and the fabric can have enough time to tumble and loosen, and fully contact the hot air to achieve efficient drying. In addition, the fixed interval makes the control method more convenient to operate, enhances its applicability and practicality, and thus expands the application scenarios of the control method.
[0117] Sixth, by real-time detection of the temperature difference ΔT and humidity difference ΔR between the bottom and middle of the inner drum, it is determined whether the fabric has reached the drying standard, which improves the accuracy of fabric drying judgment, avoids the errors that may be caused by judging a single parameter, and enables the fabric processing equipment to automatically terminate the drying process when the conditions are met. This avoids the occurrence of fabric deformation, discoloration, fiber aging, etc. that may be caused by high temperature and long-term drying, as well as the situation of insufficient drying of fabrics. It also avoids unnecessary energy consumption of fabric processing equipment, thereby improving the intelligence and control accuracy of this control method in the drying process.
[0118] Seventh, through the compact double-layer shaft system formed by the first and second drive shafts, and the synergistic effect of the electromagnetic clutch and the driven component's electromagnetic attraction and elastic separation, the fabric processing equipment can flexibly control the independent operation of the inner tub and the pulsator. This ensures both the cleaning effect of the fabric processing equipment in the washing mode and the thorough loosening of the fabric during the drying process, significantly improving the washing and drying performance and adaptability of the fabric processing equipment. The mutual cooperation of the various components in the transmission assembly forms a complete and reliable power transmission path, ensuring that the driven component can accurately and efficiently transmit power to the second drive shaft through a combination of transmission belt and gear meshing. The second transmission belt transmission between the electromagnetic clutch and the first drive shaft also ensures the stability of the power transmission of the inner tub. This allows the fabric processing equipment to flexibly control the power switching of the pulsator, enabling it to achieve different washing modes and drying processes for different fabrics, such as independent operation of the inner tub or coordinated operation of the inner tub and the pulsator. Its performance has been further improved.
[0119] Eighth, by setting up a multi-inner-tub and multi-pulse structure within the fabric processing equipment, and controlling these inner-tubs and pulsators to operate independently or in combination, the efficiency of the fabric processing equipment in processing multiple batches of different types of fabrics simultaneously is significantly improved. This saves time spent queuing in batches and enables personalized drying and washing control. It not only improves the drying and material protection of fabrics, but also allows for the separate washing of fabrics with different needs, enhancing convenience and hygiene. This expands the application scenarios and scope of the fabric processing equipment.
