Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment technology, and in particular to a drying control method, electronic equipment, and fabric processing equipment. Background Technology

[0002] In fabric processing equipment, the drying method is condensation drying. In existing condensation drying systems, the condensing and heating devices typically operate independently. On one hand, when the condensation intensity is too high, although the humid airflow can be dehumidified sufficiently, the airflow temperature is excessively reduced, resulting in an excessively low temperature of the airflow returning to the drying chamber. This reduces the rate of moisture evaporation, slows down the drying process, and lowers drying efficiency. On the other hand, when the condensation intensity is insufficient, moisture in the airflow cannot be fully removed, and moisture accumulates in the circulating airflow, causing incomplete drying and making clothes prone to dampness. Furthermore, when condensation and heating are unbalanced, there is also the problem of energy waste due to the mismatch between heating power and condensation intensity, as well as heat damage to clothing caused by excessively high temperatures within the drying chamber. Summary of the Invention

The temperature detection unit is used to detect the inlet air temperature fed into the fabric treatment cylinder; The control method includes: In response to the start of the drying program, the fan is controlled to run, driving the hot and humid airflow in the fabric treatment drum into the closed-loop air path, and after being dehumidified by the spray condensation unit and heated by the heating unit, it flows back to the fabric treatment drum. The real-time inlet air temperature collected by the temperature detection unit is acquired, and compared with a preset temperature range. The spray intensity of the spray condensation unit and the heating power of the heating unit are then adjusted in a coordinated manner to stably maintain the inlet air temperature within the preset temperature range. When the real-time air inlet temperature is lower than the lower limit of the preset temperature range, the spray intensity of the spray condensation unit is reduced, while the heating power of the heating unit is increased. When the real-time air inlet temperature is higher than the upper limit of the preset temperature range, the spray intensity of the spray condensation unit is increased, while the heating power of the heating unit is reduced.

On the one hand, this avoids excessive spray intensity leading to excessively low return air temperature and a decrease in the rate of moisture evaporation, thus slowing down the drying process and preventing "over-condensation cooling." On the other hand, it avoids insufficient spraying leading to residual moisture accumulation in the circulating airflow, or excessive heating leading to excessively high temperatures inside the fabric treatment drum, thus preventing damage to the clothing and preventing "under-condensation residue" and "overheating damage." As a result, the inlet air temperature remains stable within the preset temperature range throughout the drying process, ensuring that the heat and moisture balance is not disrupted, thus balancing drying efficiency, energy saving, and clothing protection.

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.

[0025] When washer-dryer combos use a condenser drying method to dry clothes, the condenser and heating units typically operate independently. On one hand, if the condensation intensity is too high, while the hot, humid airflow can be effectively dehumidified, the airflow temperature is excessively lowered, resulting in an excessively low temperature of the airflow returning to the drying chamber. This reduces the rate of moisture evaporation, slows down the drying process, and decreases drying efficiency. On the other hand, if the condensation intensity is insufficient, moisture in the airflow cannot be fully removed, and moisture accumulates in the circulating airflow, causing clothes to be incompletely dried and prone to dampness. Furthermore, an imbalance between condensation and heating can lead to energy waste due to a mismatch between heating power and condensation intensity, as well as heat damage to clothes caused by excessively high temperatures within the drying chamber.

[0026] Based on this, the following embodiments are proposed.

[0027] Example 1: like Figure 1As shown, this embodiment provides a drying control method for a fabric processing device, the fabric processing device including a fabric processing cylinder, a closed-loop air path 5, a fan 6, a heating unit 12, a spray condensation unit 1, and a temperature detection unit; The fan 6 is used to drive the airflow to circulate between the fabric treatment cylinder and the closed-loop air passage 5; The heating unit 12 is disposed in the closed-loop air passage 5 and is used to heat the circulating airflow. The spray condensation unit 1 is installed in the closed-loop air path 5 and is used to condense and dehumidify the circulating hot and humid airflow by spraying. The temperature detection unit is used to detect the inlet air temperature fed into the fabric treatment cylinder; The control method includes: In response to the start of the drying program, the fan 6 is controlled to run, driving the hot and humid airflow in the fabric treatment cylinder into the closed-loop air path 5. After being dehumidified by the spray condensation unit 1 and heated by the heating unit 12, the airflow returns to the fabric treatment cylinder. The real-time inlet air temperature collected by the temperature detection unit is acquired, and compared with a preset temperature range. The spray intensity of the spray condensation unit 1 and the heating power of the heating unit 12 are then adjusted in a coordinated manner to maintain the inlet air temperature stably within the preset temperature range. When the real-time air inlet temperature is lower than the lower limit of the preset temperature range, the spray intensity of the spray condensation unit is reduced, while the heating power of the heating unit is increased. When the real-time air inlet temperature is higher than the upper limit of the preset temperature range, the spray intensity of the spray condensation unit is increased, while the heating power of the heating unit is reduced.

[0028] In this embodiment, during the drying process, the fabric treatment equipment controls the fan 6 to operate in response to the start of the drying process. This drives the hot and humid airflow in the fabric treatment drum into the closed-loop air path 5. The hot and humid airflow flows sequentially through the spray condensation unit 1 and the heating unit 12. At the spray condensation unit 1, the airflow is directly contacted by the sprayed water for heat exchange and condensation dehumidification. At the heating unit 12, the airflow is heated and then returns to the fabric treatment drum, forming a closed-loop airflow. The heat carried in the circulating airflow can be recovered and utilized within the system, reducing drying energy consumption.

[0029] Furthermore, during the drying process, the real-time air inlet temperature collected by the temperature detection unit is acquired, and the real-time air inlet temperature is compared with the preset temperature range. Based on the comparison result, the spray intensity of the spray condensation unit 1 and the heating power of the heating unit 12 are adjusted in opposite phases to keep the air inlet temperature stably within the preset temperature range.

[0030] Specifically, when the real-time inlet air temperature is lower than the lower limit of the preset temperature range, it indicates that the cooling effect of the spray condensation on the airflow is too strong. At this time, the spray intensity of the spray condensation unit 1 is reduced, while the heating power of the heating unit 12 is increased. When the real-time inlet air temperature is higher than the upper limit of the preset temperature range, it indicates that the airflow condensation is insufficient or the heating is too strong. At this time, the spray intensity of the spray condensation unit 1 is increased, while the heating power of the heating unit 12 is reduced.

[0031] It should be noted that in the closed-loop system, the spray condensation unit 1 condenses and dehumidifies the drying airflow while simultaneously removing heat from the airflow, thus lowering its temperature. The heating unit 12 compensates for this cooling and raises the airflow temperature before it enters the fabric treatment drum. The effects of these two units on the airflow temperature are mutually inverse and coupled. This embodiment uses the inlet air temperature as a single feedback signal to coordinately adjust the spray intensity and heating power in opposite phases, ensuring that the dehumidification capacity of the spray condensation and the compensating heating capacity of the heating unit are matched in real time with the drying heat load. On the one hand, it avoids excessive spray intensity leading to excessively low return air temperature and a decrease in the rate of moisture evaporation, thus slowing down the drying process, i.e., avoiding "over-condensation cooling." On the other hand, it avoids insufficient spraying leading to residual moisture accumulation in the circulating airflow, or excessive heating leading to excessively high temperatures inside the fabric treatment drum, thus avoiding "under-condensation residue" and "overheating damage." As a result, the inlet air temperature remains stable within the preset temperature range throughout the drying process, maintaining a stable heat and moisture balance, and balancing drying efficiency, energy saving, and garment protection.

[0032] Optionally, in one implementation of this embodiment, the preset temperature range is dynamically adjusted according to the execution progress of the drying program. The drying program includes an initial stage and subsequent stages performed sequentially. The step of dynamically adjusting the preset temperature range according to the execution progress of the drying program includes: The amount of condensate discharged from the spray condensation unit 1 is obtained; when the amount of condensate is greater than a preset high condensate threshold, the drying process is determined to be in the initial stage, and the preset temperature range is maintained as the first temperature range; when the amount of condensate decreases from greater than the preset high condensate threshold to less than or equal to the preset low condensate threshold, the drying process is determined to enter the subsequent stage from the initial stage, and the preset temperature range is adjusted from the first temperature range to the second temperature range. Wherein, the preset low drainage threshold is less than the preset high drainage threshold, and the upper limit of the second temperature range is less than the upper limit of the first temperature range.

[0033] In this embodiment, under stable closed-loop operation, the amount of condensate discharged by the spray condensation unit 1 is approximately equal to the amount of water evaporated from the clothes. The condensate drainage volume directly and quantitatively characterizes the change in the moisture content of the clothes during the drying process: initially, the clothes have a high moisture content and vigorous evaporation, resulting in a large drainage volume; as drying progresses, the moisture content of the clothes gradually decreases, evaporation slows down, and the drainage volume decreases accordingly. Using condensate drainage volume as a stage criterion is more fundamental than using only the inlet air temperature, avoiding misjudgments caused by fluctuations in ambient temperature, heating power, and other factors. Simultaneously, by setting preset high and low drainage volume thresholds to form a hysteresis interval, the system only determines whether to proceed to the next stage when the drainage volume clearly decreases from above the high threshold to below the low threshold. This avoids frequent switching of stage determination when the drainage volume fluctuates around the threshold, ensuring the stability and reliability of the preset temperature range adjustment.

[0034] Furthermore, through the aforementioned phased control, the initial stage maintains a higher first temperature range, using higher air temperature to drive rapid evaporation of moisture from the clothes and shorten drying time. In subsequent stages, the temperature switches to a lower second temperature range to avoid continuous high-temperature heating of clothes that are nearing dryness, preventing overheating damage to the fabric and fiber aging, and reducing ineffective heating energy consumption. This achieves a phased temperature control effect of "high-temperature rapid drying and gentle finishing," balancing initial drying efficiency with subsequent garment protection.

[0035] Optionally, in one implementation of this embodiment, in the subsequent stage, the control method further includes: obtaining the drainage rate of the condensate discharged by the spray condensation unit 1; When the drainage rate is less than or equal to the preset end drainage rate, the preset temperature range is adjusted from the second temperature range to the third temperature range, and the water supply to the spray condensation unit 1 is reduced simultaneously. The upper limit of the third temperature range is less than the upper limit of the second temperature range.

[0036] In this embodiment, the drainage rate reflects the degree of decay of the drying rate of the clothes in the subsequent stages (i.e., the rate of moisture evaporation). When the drainage rate decreases below the preset final drainage rate, it indicates that the clothes are basically dry, moisture evaporation tends to stop, and the drying process enters the final stage. At this time, on the one hand, the preset temperature range is further lowered to the third temperature range to avoid continuing to heat the basically dried clothes at high temperatures, preventing problems such as overheating damage, hardening, fading, and static electricity caused by over-drying; on the other hand, the water supply to the spray condensation unit 1 is reduced simultaneously. Since the clothes are basically dry and the moisture load in the humid airflow is very low, there is no need to maintain high-intensity spray condensation, thereby avoiding water waste caused by excessive spraying, avoiding excessive dehumidification of the dried clothes, and reducing the working energy consumption and noise of the spray water supply system.

[0037] Therefore, this embodiment achieves a gentle final control of "synchronous decay of air temperature and condensation intensity" in the subsequent stages: as the drying process progresses, the target air inlet temperature is gradually reduced, and the spray condensation intensity is reduced in sync. The two match the continuous decrease in the moisture content of the clothes, so that the heat and humidity balance is not out of control in the final stage of drying, the moisture content of the clothes is uniform, and the clothes feel dry. The entire process takes into account both drying quality and energy and water conservation.

[0038] It is understood that the drying control method provided in the above embodiments, through closed-loop circulation, coordinated spray condensation and heating, and staged temperature control based on condensate drainage volume and rate, achieves stable maintenance of the inlet air temperature and adaptive matching of the drying process throughout the drying process. This effectively solves the problems of insufficient condensation leading to moisture residue and imbalance between condensation and heating causing decreased drying efficiency or damage to clothing in the prior art, thus improving drying quality and user experience. The preset temperature range, preset high drainage threshold, preset low drainage threshold, preset final drainage rate, and other parameters involved in the embodiments can be reasonably set by those skilled in the art based on the clothing material, load, and drying requirements; this application does not specifically limit these parameters.

[0039] Optionally, in one implementation of this embodiment, such as Figure 2-6 As shown, the fabric processing tube includes: an outer tube 9 and an inner tube 11 disposed within the outer tube 9; The air inlet of the closed-loop air passage 5 is connected to the outer cylinder 9, and the air outlet of the closed-loop air passage 5 is connected to the inlet of the inner cylinder 11. The spray condensation unit 1 includes an independent injection chamber. A condensation chamber 108 is formed on the outer side of the bottom wall 1011 of the box body of the spray condensation unit 1. A spray structure 102 is provided at the top of the condensation chamber 108. The condensing chamber 108 is connected to the outer cylinder 9 through the first air duct 3 and to the closed-loop air path 5 through the second air duct 4. It is used to introduce the hot and humid drying air in the outer cylinder 9 into the condensing chamber 108 to exchange heat with the spray water provided by the spray structure 102, and then introduce it into the closed-loop air path 5.

[0040] In this embodiment, when the fabric processing equipment is performing the drying process, at least part of the hot and humid airflow enters the condensing chamber 108 from the inner cylinder 11 and the outer cylinder 9 along the first air duct 3. By setting a spray structure 102 at the top of the condensing chamber 108, a larger area of ​​spray water is sprayed into the condensing chamber 108, thereby giving the condensing chamber 108 a larger heat exchange surface. The spray water and the hot and humid airflow directly exchange heat, improving the condensation efficiency and effectively reducing moisture residue caused by insufficient condensation.

[0041] The fabric processing equipment proposed in this embodiment, without increasing the equipment space, sets up a condensation chamber at the bottom of the spray condensation unit, thereby improving condensation efficiency and optimizing the use of structural space. The condensed gas, driven by the fan 6, enters the return air inlet through the second air duct 4 and mixes with the gas condensed in the rear cylinder and the rear air duct before being sent into the closed-loop circulation air path 5. The gas entering the closed-loop circulation air path 5 is heated and dried by the heating unit 12 and then re-enters the inner cylinder 11 through the air inlet to complete the gas circulation.

[0042] It should be noted that the spray condensation unit 1 includes an independent injection chamber. "Independent" means that the inlet valve of the fabric processing equipment has a pipe supplying water to the injection chamber and also a pipe supplying water to the spray structure; the two pipes supply water independently. Furthermore, "independent" also indicates that the injection chamber can be independently extracted or pushed back within the spray condensation unit. The spray condensation unit 1 is fixed within the outer casing of the fabric processing equipment, and the fluid within the injection chamber will not leak out under physical isolation conditions (e.g., the chamber's enclosure). A partition is installed inside the spray condensation unit 1, dividing the inner chamber into... An independent dispensing chamber; the dispensing method of the dispensing chamber can be divided into one-time dispensing and automatic dispensing. In the case of one-time dispensing, the dispensing chamber only includes the dispensing cavity. The detergent added in the dispensing cavity is flushed into the inner drum 11 through the water inlet channel to realize dispensing. In the case of automatic dispensing, the dispensing chamber includes the dispensing cavity and the storage cavity. The main control board of the fabric processing equipment determines the amount of detergent to be dispensed according to the amount of laundry and controls the dispensing pump to dispense the corresponding amount of detergent from the storage cavity into the dispensing cavity. The detergent is then flushed into the inner drum 11 through the water inlet channel.

[0043] It should be noted that rear cylinder condensation refers to the installation of a condenser plate 8 between the bottom of the outer cylinder 9 and the bottom of the inner cylinder 11 to condense the humid and hot airflow discharged from the inner cylinder 11, or the direct use of the bottom of the outer cylinder 9 as a condenser plate to condense the humid and hot airflow. Rear air duct condensation refers to the installation of a condenser section 501 in the closed-loop air path 5 to exchange heat and dehumidify the humid and hot airflow through condensate.

[0044] In this embodiment, based on the rear cylinder condenser and the air duct condenser, the condensation chamber formed by the bottom wall 1011 of the spray condensation unit 1 is further designed to condense the hot and humid airflow, thereby improving the condensation efficiency of the equipment within the original size space.

[0045] Preferably, the bottom wall 1011 of the box is a heat-conducting metal wall, which is not easy to rust and further improves the heat exchange and dehumidification efficiency of the hot and humid airflow in the condensation chamber 108.

[0046] Optionally, in one implementation of this embodiment, such as Figure 3 , 4As shown, the spray structure includes a spray channel 1021, which is formed inside the bottom wall 1011 of the box. An inlet 105 communicating with the spray channel 1021 is provided on the bottom wall 1011 of the box. Spray holes 1022 are provided at intervals in the spray channel 1021.

[0047] In this embodiment, the spray channel 1021 located inside the bottom wall 1011 of the box corresponds to the condensation chamber 108. The spray channel 1021 is formed by relying on the bottom wall 1011 of the original spray condensation unit 1, without the need to add an independent spray chamber. This makes full use of the original empty space of the dispensing box, simplifies the layout of the whole machine's pipeline and cavity, and reduces the internal volume occupied by the equipment.

[0048] The inlet 105 is connected to the spray channel 1021. After the water flows into the spray channel 1021 through the inlet 105, it is evenly discharged downward from each spray hole 1022 by the liquid surface pressure. The porous structure of the bottom wall 1011 of the box can form a planar water curtain on the cross-section of the condensing chamber 108, so as to maximize the condensing area of ​​the condensing chamber 108 and thus maximize the condensing efficiency of the condensing chamber.

[0049] Preferably, the spray channel 1021 is a continuously bent channel.

[0050] Optionally, in one implementation of this embodiment, the diameter of the spray hole 1022 is 1 mm to 3 mm.

[0051] In this embodiment, by setting the diameter of the spray holes 1022 to 1mm to 3mm, the sprayed water is made into a fine mist, which increases the spray surface of the sprayed water in the condensation chamber 108, thereby improving the condensation efficiency and reducing the amount of water used for condensation, achieving a water-saving effect. If the hole diameter is too small, less than 1mm, the channel is too narrow, and tiny impurities and scale in the water can easily clog the spray holes 1022, resulting in uneven water distribution. By designing the diameter of the spray holes 1022 to be in the range of 1 to 3mm, both the atomization pattern can be ensured and the clogging failure caused by scale and impurities can be greatly reduced.

[0052] Optionally, in one implementation of this embodiment, such as Figure 2 As shown, an air inlet and water outlet 1014 is provided on the bottom cavity wall of the condensing chamber 108, and the air inlet and water outlet 1014 is connected to the first air duct 3. An air outlet 1013 is provided on the side cavity wall of the condensing chamber 108, which is connected to the second air duct 4.

[0053] In this embodiment, the hot and humid airflow enters the condensing chamber 108 through the inner cylinder 11 and outer cylinder 9 along the first air duct 3 and through the air inlet and water outlet 1014. By setting a spray structure 102 at the top of the condensing chamber 108, a larger area of ​​spray water is sprayed into the condensing chamber 108, thereby giving the condensing chamber 108 a larger heat exchange surface, improving condensation efficiency, and effectively reducing moisture residue caused by insufficient condensation. The condensed gas, driven by the fan 6, enters the return air port through the air outlet 1013 and the second air duct 4, mixes with the gas condensed by the rear cylinder and the rear air duct, and is sent into the closed-loop air path 5. The gas entering the closed-loop air path 5 is heated and dried by the heating unit 12 and then enters the inner cylinder 11 again through the air inlet to complete the gas circulation. The spray water is discharged from the air inlet and water outlet 1014 under the action of gravity to the outer cylinder drain pipe of the fabric processing equipment.

[0054] Optionally, in one implementation of this embodiment, such as Figure 2 , 6 As shown, at least part of the bottom wall of the condensing chamber 108 is constructed as an inclined wall, and the air inlet / outlet 1014 is located at the bottommost end of the bottom wall of the condensing chamber 108. The inclined wall is used to guide the condensate in the condensing chamber 108 to the air inlet / outlet 1014.

[0055] In this embodiment, as Figure 5 As shown, by constructing at least part of the bottom wall of the condensation chamber 108 as an inclined wall, for example, the angle between the inclined wall and the horizontal plane can be 15° to 45°, it is ensured that the condensate drains smoothly under the action of gravity, avoiding water accumulation.

[0056] Optionally, in one implementation of this embodiment, such as Figure 1 As shown, the fabric processing equipment further includes a condensate drain pipe 7, one end of which is connected to the air inlet / outlet 1014, and the other end is connected to the outer cylinder drain pipe of the fabric processing equipment. The middle part of the condensate drain pipe 7 is connected to the first air duct 3.

[0057] In this embodiment, the condensate drain pipe 7 can smoothly guide the airflow in the first air duct 3 into the condensation chamber 108, and can also guide the spray water discharged from the air inlet and water outlet 1014 of the condensation chamber 108 into the outer cylinder drain pipe of the fabric processing equipment, further simplifying the internal pipe design of the fabric processing equipment.

[0058] It should be noted that the other end of the condensate drain pipe 7 is connected to the outer cylinder drain pipe and is located downstream of the drain valve of the fabric processing equipment. The condensate discharged from the condensate drain pipe 7 is not affected by the opening and closing of the drain valve and can be directly discharged to the outside of the fabric processing equipment.

[0059] A valve can be installed on the condensate drain pipe 7. During the drying process, the valve on the condensate drain pipe 7 remains open.

[0060] Optionally, in one implementation of this embodiment, such as Figure 2 As shown, the first air duct 3 and / or the second air duct 4 are flexible pipes.

[0061] In this embodiment, preferably, both the first air duct 3 and the second air duct 4 are flexible rubber tubes. One end of the second air duct 4 is connected to the condensation chamber 108, and the other end is connected to the return air port of the rear air duct section of the closed-loop air path 5. The airflow condensed in the condensation chamber 108 returns to the closed-loop air path 5 along the second air duct 4. The use of flexible rubber tubes for both the first air duct 3 and the second air duct 4 can ensure the sealing of the pipe head connection while allowing a certain displacement. When the fabric processing equipment is working, the operation of the fan and the rotation of the inner cylinder 11 will generate continuous vibration. The flexible rubber tube has flexible deformation capability, which can effectively block the vibration transmission between the condensation chamber 108, the closed-loop air path 5, and the inner cylinder 11, avoid the rigid pipeline from loosening and cracking due to resonance, and at the same time weaken the abnormal noise of the pipeline caused by vibration.

[0062] Optionally, in one implementation of this embodiment, such as Figure 2 As shown, the fabric processing equipment further includes: a condenser plate 8, which is disposed between the bottom of the outer cylinder 9 and the bottom of the inner cylinder 11 of the fabric processing equipment. The condenser plate 8 is provided with a condenser plate water inlet that is connected to the water inlet valve of the fabric processing equipment. An outer cylinder air outlet that is connected to the air inlet end of the closed-loop air passage 5 is opened on the bottom of the outer cylinder 9.

[0063] In this embodiment, water is supplied to the inlet of the condenser plate through the water inlet valve, so that the water flow fills the condenser plate 8. The hot and humid airflow discharged from the inner cylinder 11 exchanges heat with the condenser plate 8 to achieve the dehumidification effect. The condenser plate 8 can be a condenser plate with a condensation cavity composed of two plates. The water inlet valve supplies water to the condensation cavity. The condenser plate 8 exchanges heat with the hot and humid airflow through the indirect wall. The condenser plate 8 can also form a condensation cavity between itself and the inner wall of the bottom of the outer cylinder 9. The condenser plate 8 can also be a single plate structure, on which the condensate directly exchanges heat with the hot and humid airflow. In the fabric processing equipment proposed in this embodiment, during the drying process, part of the hot and humid airflow discharged from the inner cylinder 11 directly exchanges heat and dehumidifies with the condenser plate 8, while part enters the condensation chamber 108 from the inner cylinder 11 along the first air duct 3. By setting a spray structure 102 at the top of the condensation chamber 108, a larger area of ​​spray water is sprayed into the condensation chamber 108, thereby giving the condensation chamber 108 a larger heat exchange surface, improving condensation efficiency, and effectively reducing moisture residue caused by insufficient condensation. The condensed gas, driven by the fan 6, enters the return air port through the second air duct 4 and mixes with the gas condensed by the rear cylinder, i.e., the gas condensed by the condenser plate 8, and is sent into the closed-loop circulation air path 5. The gas entering the closed-loop circulation air path 5 is heated and dried by the heating unit 12 and then enters the inner cylinder 11 again through the air inlet to complete the gas circulation. The diversion condensation method further improves the condensation efficiency of the fabric processing equipment.

[0064] It should be noted that the outer cylinder air outlet includes an upper air outlet 901 opened on the bottom of the outer cylinder 9 and a lower air outlet 902 opened on the side wall of the outer cylinder 9. The arrangement of the two air outlets allows the airflow between the outer cylinder 9 and the inner cylinder 11 to enter the closed circulation air path 5 relatively quickly.

[0065] Optionally, in one implementation of this embodiment, such as Figure 2 As shown, a condensation section 501 is provided in the closed-loop air passage 5. The condensation section 501 is used to condense the hot and humid airflow entering the closed-loop air passage 5. The condensation section 501 is provided with a condensation section inlet that is connected to the water inlet valve of the fabric processing equipment.

[0066] In this embodiment, water is supplied to the inlet of the condensing section through the inlet valve. Part of the hot and humid airflow discharged from the inner cylinder 11 exchanges heat with the condensate entering the condensing section 501, achieving a dehumidification effect. In the fabric processing equipment proposed in this embodiment, during the drying process, part of the hot and humid airflow discharged from the inner cylinder 11 directly exchanges heat and dehumidifies with the condensing section 501, while part enters the condensing chamber 108 from the inner cylinder 11 along the first air duct 3. By setting a spray structure 102 at the top of the condensing chamber 108, a larger area of ​​spray water is sprayed into the condensing chamber 108, thereby giving the condensing chamber 108 a larger heat exchange surface, improving condensation efficiency, and effectively reducing moisture residue caused by insufficient condensation. The condensed gas, driven by the fan 6, enters the return air inlet through the second air duct 4 and mixes with the gas condensed in the rear cylinder (i.e., after passing through the condensation section 501). The mixture is then sent into the closed-loop air path 5. The gas entering the closed-loop air path 5 is heated and dried by the heating unit 12 and then enters the inner cylinder 11 through the air inlet to complete the gas circulation. The diversion condensation method further improves the condensation efficiency of the fabric processing equipment.

[0067] Optionally, in one implementation of this embodiment, such as Figure 7 As shown, the control method further includes: when the fabric processing equipment is in the washing program, controlling the water inlet valve to provide a first flow rate of water to the delivery chamber; and when the fabric processing equipment is in the drying program, controlling the water inlet valve to provide a second flow rate of water to the spray structure. The first flow rate is greater than the second flow rate.

[0068] In this embodiment, when the fabric treatment equipment is in the washing program and the drying program, water with different flow rates is supplied to the injection chamber and spray structure of the spray condensation unit 1, respectively. That is, the water inlet valve is configured to have two working states: washing mode and condensation mode, so as to realize independent control of the fabric treatment agent rinsing and condensation functions, ensuring that the fabric treatment agent residue is thoroughly cleaned, while not affecting the drying and condensation effect.

[0069] The inlet valve has two modes. When the washing program is running, the high flow mode can be switched to rinse away any residual fabric treatment agent in the dispensing chamber. When the drying program is running, the low flow mode can be switched to adapt to the water mist spray. By switching modes, the rinsing and condensation of the fabric treatment agent can be independently controlled, improving the system's adaptability.

[0070] Furthermore, the washing stage uses a large flow of water with strong impact force, which can thoroughly flush the inner wall of the dispensing box and dead corners of the flow channel, completely removing residual fabric softener, detergent and other fabric treatment agents, preventing long-term accumulation of agents that can cause mold, clumping and blockage of pipes; the drying stage switches to a small flow of water to meet the working requirements of water mist spray condensation, with uniform and stable water atomization effect, ensuring the condensation heat exchange efficiency of the drying system, and the two operating conditions do not interfere with each other.

[0071] The drying and condensing process requires only a small amount of water to meet the atomization needs. Compared with a continuous large flow of water, the small flow of water can effectively save water consumption. At the same time, the low flow of water has less impact, which can weaken the abnormal noise generated by the water flow and optimize the operating noise of the equipment during the drying process. During the washing stage, a large flow is output as needed, and a high flow is only used in the chemical rinsing scenario to avoid the ineffective waste of water resources.

[0072] Optionally, in one implementation of this embodiment, such as Figure 8 , 9 As shown, the control method further includes: obtaining the temperature difference between the inner cylinder air inlet 111 and the inner cylinder air outlet 112 of the fabric processing equipment, determining the preset temperature range to which it belongs based on the temperature difference, and controlling the water inlet valve of the fabric processing equipment to selectively supply water to at least one of the spray structure, the condenser plate water inlet and the condenser section water inlet.

[0073] In this embodiment, preferably, the step of determining the preset temperature range to which the fabric treatment equipment belongs based on the temperature difference and controlling the water inlet valve of the fabric treatment equipment to selectively supply water to at least one of the spray structure, the water inlet of the condensation tray 8, and the water inlet of the condensation section 501 includes: If the temperature difference is greater than or equal to the first preset temperature, the water inlet valve is controlled to supply water to the spray structure, the condenser plate inlet, and the condenser section inlet. If the temperature difference is less than the first preset temperature and greater than the second preset temperature, then the water inlet valve is controlled to supply water to both the spray structure and the condensation section inlet. If the temperature difference is less than or equal to the second preset temperature and greater than the third preset temperature, then the water inlet valve is controlled to supply water to the spray structure. If the temperature difference is less than or equal to the third preset temperature, then control the water inlet valve to stop supplying water; Wherein, the first preset temperature is greater than the second preset temperature, and the second preset temperature is greater than the third preset temperature.

[0074] Based on the temperature difference between the air inlet and outlet of the inner drum 11 of the fabric processing equipment, the drying process is divided into three different zones. Each zone employs a different condensation combination method to prevent damage to the inner drum 11 load caused by high temperatures during moisture evaporation. Specifically, the temperature difference between the air inlet and outlet of the inner drum 11 is divided into four zones by a first preset temperature, a second preset temperature, and a third preset temperature. Based on the measured temperature difference between the air inlet and outlet of the inner drum 11, the condensation combination method used by the fabric processing equipment is determined to achieve a suitable condensation effect.

[0075] In this embodiment, the proposed control method can match the heat load of different drying stages and dynamically adapt the condensation effect. The temperature difference between the inlet and outlet of the inner cylinder 11 directly reflects the hot air temperature, water vapor content and drying intensity inside the cylinder. The larger the temperature difference, the higher the hot air temperature, the larger the moisture carrying capacity and the higher the overall heat load. The scheme divides the temperature difference into four intervals and matches the multiple water supply modes of the condensation section 501, condensation plate 8 and spray structure water inlet 105 step by step. When the temperature difference is high, full-area condensation is activated, that is, the water inlet valve is controlled to supply water to the water inlet 105, condensation plate 8 and condensation section 501. When the temperature difference is medium, the water inlet valve is controlled to supply water to the water inlet 105 and condensation section 501, realizing two condensation modes of condensation section 501 and spray condensation unit 1. When the temperature difference is low, only basic water supply is retained, the water inlet valve is controlled to supply water to the water inlet 105, and only the condensation chamber 108 at the bottom of the spray condensation unit 1 needs to be condensed. The control method proposed in this embodiment, compared with the fixed flow rate and fixed point water supply mode, can match the condensation capacity in real time with the drying process, maintain the temperature of the air duct and cylinder in a reasonable range throughout the process, and keep the condensation heat exchange efficiency at the optimal state.

[0076] During the initial drying stage, when the temperature difference is greatest under high load, the all-area water supply can quickly absorb a large amount of residual heat and moisture, suppressing localized heat accumulation inside the drum and air ducts. This prevents the inner and outer drums and the closed-loop air circulation path from being in an overheated state for extended periods, thus preventing high-temperature aging of metal components and heat-induced deformation of seals. Simultaneously, it avoids damage to the fabric due to excessively high temperatures inside the drum, resolving issues such as fabric stiffening, fading, and material aging caused by high-temperature drying. As drying progresses, the humidity and temperature inside the drum gradually decrease, and the water supply points are progressively reduced until water supply is stopped. This avoids excessive cooling that could affect drying efficiency, achieving a balance between temperature control and drying effect.

[0077] Example 2 This embodiment provides an electronic device, including: a processor; A memory on which computer programs are stored; When the processor executes the computer program, it implements the drying control method in Embodiment 1.

[0078] The electronic device in this embodiment can implement the drying control method in Embodiment 1, and therefore has all the beneficial effects of the drying control method in Embodiment 1, which will not be repeated here.

[0079] Example 3 This embodiment provides a fabric processing device, including: executing the drying control method in Embodiment 1 or including the electronic device in Embodiment 2.

[0080] Since the fabric processing equipment in this embodiment, such as a washer-dryer combo machine, can execute the drying control method in Embodiment 1 or include the electronic equipment in Embodiment 2, it has all the beneficial effects of the drying control method in Embodiment 1 or the electronic equipment in Embodiment 2, and will not be described again.

[0081] In summary, the ingenious design of the drying control method lies in: First, using the inlet air temperature as a feedback signal, the spray intensity and heating power are adjusted in opposite phases to ensure that the dehumidification capacity of the spray condensation and the compensating heating capacity of the heating unit are matched in real time with the drying heat load. On the one hand, this avoids excessive spray intensity leading to excessively low return air temperature and a decrease in the rate of moisture evaporation, thus slowing down the drying process and preventing "over-condensation cooling." On the other hand, it avoids insufficient spraying leading to residual moisture accumulation in the circulating airflow, or excessive heating leading to excessively high temperatures inside the fabric treatment drum, thus preventing damage to the clothing and avoiding "under-condensation residue" and "overheating damage." As a result, the inlet air temperature remains stable within the preset temperature range throughout the drying process, ensuring that the heat and moisture balance is not out of control, thus balancing drying efficiency, energy saving, and clothing protection.

[0082] Secondly, during the drying process, at least part of the hot and humid airflow enters the condensing chamber through the inner and outer cylinders along the first air duct. By installing a spray structure at the top of the condensing chamber, a larger area of ​​spray water is applied to the chamber, resulting in a larger heat exchange surface. This allows for direct heat exchange between the spray water and the hot and humid airflow, improving condensation efficiency and effectively reducing residual moisture caused by incomplete condensation. Furthermore, the fabric processing equipment, without increasing the equipment space, incorporates a condensing chamber at the bottom of the spray condensation unit, achieving both improved condensation efficiency and optimized utilization of structural space.

[0083] Third, the bottom wall of the fabric processing equipment's feeding box is used as a spray structure, eliminating the need for an additional independent spray chamber. This fully utilizes the existing space in the feeding box, streamlining the overall piping and chamber layout and reducing the internal volume of the equipment. Water flows into the spray channel through the inlet, and relies on surface pressure to evenly spray downwards from each spray hole, forming a surface water curtain. This maximizes the contact area with the bottom wall of the box, resulting in a larger heat exchange surface and higher utilization.

[0084] Fourth, by constructing at least part of the bottom wall of the condensation chamber as an inclined wall, for example, the angle between the inclined wall and the horizontal plane can be between 15° and 45°, it is ensured that the condensate can be smoothly discharged through the condensate drain pipe under the action of gravity, thus avoiding water accumulation.

[0085] Fifth, the drying control method can match the heat load at different stages of drying, dynamically adapting the condensation effect. The temperature difference between the inlet and outlet of the inner cylinder directly reflects the hot air temperature, moisture content, and drying intensity inside the cylinder. The larger the temperature difference, the higher the hot air temperature, the greater the moisture carrying capacity, and the higher the overall heat load. The system is divided into four temperature zones, progressively matching multiple water supply modes for the condensing section, condensing pan, and inlet pipe. At high temperature differences, full-area condensation is activated, meaning the inlet valve supplies water to the inlet pipe, condensing pan, and condensing section. At medium temperature differences, the inlet valve supplies water to both the inlet pipe and condensing section, achieving two condensation modes: the condensing section and the spray condensation unit. At low temperature differences, only basic water supply is maintained, controlling the inlet valve to supply water to the inlet pipe, requiring only the spray condensation unit for condensation. Compared to fixed flow and fixed-point water supply modes, this control method can match the condensation capacity in real time according to the drying process, maintaining the temperature in the air duct and inside the cylinder within a reasonable range throughout the process, ensuring optimal condensation heat exchange efficiency.
