[0002] When using fabric treatment equipment, users may overdo the detergent or, when using smart dispensing, inaccurately dispense the detergent, resulting in a large amount of foam during the wash cycle. Because foam accumulates between the inner and outer drums, excessive foam can hinder the dehydration process, resulting in a longer wash time.

[0003] The method for eliminating foam in ordinary fabric processing equipment is generally to wait for the foam to disappear on its own, but this takes a long time and affects the user experience. Summary of the Invention

[0004] The embodiments of the present application provide a defoaming control method for a fabric processing device and a fabric processing device. By collecting the actual power value of the drum motor in real time during the dehydration process, it can quickly determine whether there is an excessive foam problem. This method can promptly detect the impact of foam on the washing process, thereby avoiding the time-consuming process of waiting for the foam to disappear on its own in the traditional method. At the same time, according to the abnormal power level of the actual power value, the corresponding defoaming process is determined. This method can accurately control the degree of defoaming according to different foam amounts, thereby improving the defoaming efficiency and effect. Specifically:

[0005] A first aspect of an embodiment of the present application provides a defoaming control method for a fabric processing device, the control method comprising:

[0006] In the dehydration program, the actual power value of the drum motor at the preset speed is collected, and it is determined whether the actual power value is in an abnormal power gear;

[0007] If the actual power value is in an abnormal power gear, the current defoaming process is determined according to the abnormal power gear level at which the actual power value is located;

[0008] Different abnormal power gear levels correspond to different defoaming processes, and the higher the abnormal power gear level, the more foam there is in the drum, and the higher the defoaming degree of the corresponding defoaming process.

[0009] In the above technical solution, the fabric processing device has a spray device, which is used to spray water into the drum when turned on;

[0010] The fabric processing equipment has different operating parameters when performing different defoaming processes, wherein the operating parameters include the speed of the drum motor and the opening time of the spray device.

[0011] In the above technical solution, the higher the abnormal power gear level is, the lower the drum motor speed is and the longer the spray device is turned on in the corresponding defoaming process;

[0012] The rotation speed of the drum motor is less than the preset rotation speed when the actual power value of the drum motor is collected.

[0013] In the above technical solution, the control method further includes:

[0023] In the above technical solution, in the current defoaming process, the opening or closing of the spraying device is controlled according to the change of the water level in the barrel.

[0024] In the above technical solution, the opening or closing of the spray device is controlled according to the change of the water level in the drum, including:

[0025] Obtain the water level value F in the drum before the defoaming process is started and the water level value F1 in the drum after the defoaming process is started, and obtain the water inlet flow value H of the spray device after the defoaming process is started;

[0026] Calculate the difference X between H and F and the difference X1 between H and F1, compare X and X1, and control the opening or closing of the spray device based on the comparison result of X and X1.

[0027] In the above technical solution, the control of opening or closing the spray device based on the comparison result of X and X1 includes:

[0028] If X1 is less than or equal to k times X, the sprinkler is controlled to be closed, and when X1 is greater than k times X, the sprinkler is controlled to be opened again;

[0029] The value of k is between 0 and 1.

[0030] In the above technical solution, the control method further includes:

[0031] Determine the value of k based on the specific defoaming process corresponding to the abnormal power level;

[0032] The higher the defoaming degree, the larger the k value corresponding to the defoaming process.

[0052] Background

[0053] When using fabric treatment equipment, users may overdo the detergent or, when using smart dispensing, inaccurately dispense the detergent, resulting in a large amount of foam during the wash cycle. Because foam accumulates between the inner and outer drums, excessive foam can hinder the dehydration process, resulting in a longer wash time.

[0054] The method for eliminating foam in ordinary fabric processing equipment is generally to wait for the foam to disappear on its own, but this takes a long time and affects the user experience.

[0055] For example, a drum washing machine, such as a fabric treatment device, can produce excessive amounts of foam if too much detergent is added. This excess foam fills the inner and outer drums, as well as the inner drum. When the motor drives the inner drum, the foam creates significant friction, causing the machine to require more power during the spin cycle and preventing the spin cycle from completing.

[0056] Based on this, Figure 1-Figure 3 As shown, the first aspect of the embodiment of the present application provides a defoaming control method for a fabric processing device, the control method comprising:

[0057] In the dehydration program, the actual power value of the drum motor at the preset speed is collected, and it is determined whether the actual power value is in an abnormal power gear;

[0058] If the actual power value is in an abnormal power gear, the current defoaming process is determined according to the abnormal power gear level at which the actual power value is located;

[0059] Different abnormal power gear levels correspond to different defoaming processes, and the higher the abnormal power gear level, the more foam there is in the drum, and the higher the defoaming degree of the corresponding defoaming process.

[0060] In the embodiments of the present application, by collecting the actual power value of the drum motor in real time during the dehydration process, it is possible to quickly determine whether there is an excessive foam problem. This method can promptly detect the impact of foam on the washing process, thereby avoiding the time-consuming process of waiting for the foam to dissipate on its own in traditional methods. At the same time, the corresponding defoaming process is determined based on the abnormal power level of the actual power value. This method can accurately control the degree of defoaming according to different foam amounts, thereby improving defoaming efficiency and effectiveness.

[0061] Furthermore, in some possible embodiments, the fabric processing apparatus has a spray device, which is used to spray water into the drum when turned on;

[0062] The fabric processing equipment has different operating parameters when performing different defoaming processes, wherein the operating parameters include the speed of the drum motor and the opening time of the spray device.

[0063] In the embodiment of the present application, water is sprayed into the drum through a spray device, which can directly physically flush the foam in the drum and accelerate the rupture and elimination of the foam. This direct physical effect can significantly improve the efficiency of foam removal. At the same time, different defoaming processes correspond to different operating parameters, including the speed of the drum motor and the opening time of the spray device. This design allows the device to flexibly adjust the defoaming strategy according to the actual situation of the foam amount to achieve the best defoaming effect. Specifically, by controlling the opening time of the spray device through the foam amount, the amount of water sprayed into the drum can be accurately controlled. This helps to provide an appropriate amount of water to help eliminate foam under different foam amounts and avoid waste of water resources. Controlling the speed of the drum motor through the foam amount can avoid the problem of motor overheating caused by excessive foam.

[0064] Furthermore, in some possible implementations, the higher the abnormal power gear level is, the lower the speed of the drum motor is and the longer the spray device is turned on during the corresponding defoaming process;

[0065] The rotation speed of the drum motor is less than the preset rotation speed when the actual power value of the drum motor is collected.

[0066] In the embodiment of the present application, by reducing the speed of the drum motor and extending the opening time of the spray device, severe foaming situations can be more effectively addressed. Specifically, low-speed rotation helps to reduce the friction between the foam and the clothes while also preventing the motor from overheating due to the friction between the drum and the foam, while long-term spraying helps to remove the foam more thoroughly. In addition, when the amount of foam is large, reducing the speed of the drum motor can reduce the additional foam generated by the high-speed rotation of the motor. Based on this, when a higher degree of defoaming is required, by reducing the speed and extending the spraying time, water resources and mechanical actions can be more effectively utilized to achieve a better defoaming effect while effectively preventing the motor from overheating, avoiding overheating or damage to the motor due to excessive foam.

[0067] Furthermore, in some possible implementations, the control method further includes:

[0068] When it is determined that the actual power value is at an abnormal power gear, controlling the drum motor to reduce speed to 0;

[0069] Starting the current defoaming process, during the current defoaming process, controlling the drum motor to increase its speed to a target speed corresponding to the current defoaming process, and starting the drainage pump to drain water during the speed increase process;

[0070] The method further includes: turning on the spray device after the drum motor runs at the target speed for a preset period of time, and keeping the drainage pump turned on.

[0071] In the embodiment of the present application, after the defoaming process is started, the drum motor is controlled to slow down to 0 rpm and then speeded up to the target speed, so as to ensure a smooth start of the defoaming process and avoid damage to clothes or equipment due to sudden speed changes. At the same time, the spray device is turned on after the motor runs at the target speed for a preset period of time, so as to ensure that the foam in the drum has been preliminarily dispersed and reduced by the rotation of the motor before spraying, thereby improving the efficiency of spray defoaming. In addition, the drain pump is turned on immediately after the defoaming process is started to drain the water, so as to promptly remove excess water and foam in the drum, reduce the adverse effects of foam on the operation of the equipment, such as motor overload or poor drainage, and prepare for the subsequent dehydration step, thereby improving the dehydration efficiency.

[0072] That is, the fabric processing equipment in the embodiment of the present application can intelligently adjust the motor speed and drainage according to the needs of the defoaming process. This adaptive adjustment mechanism makes the equipment more intelligent and able to cope with different washing challenges.

[0073] Furthermore, in some possible implementations, the preset rotational speed is between 400 rpm and 500 rpm.

[0074] The reason motor power values ​​are collected between 400 and 500 rpm in this embodiment is because the 200-350 rpm speed range is a resonance range. The washing machine resonates at this speed, so it needs to quickly skip this speed range during the ramp-up phase, making it unsuitable for power value collection. However, the power value is relatively stable after 400 rpm, reflecting the actual situation.

[0075] Furthermore, in some possible implementations, the power gears of the fabric processing device include a first power gear at a normal power gear, and a second power gear, a third power gear, and a fourth power gear at an abnormal power gear;

[0076] The defoaming process includes a first defoaming process corresponding to the second power level, a second defoaming process corresponding to the third power level, and a third defoaming process corresponding to the fourth power level.

[0077] In the embodiment of the present application, by setting a normal power gear and three abnormal power gears, the operating status of the washing machine under different foam amounts can be clearly distinguished. This clear division helps to accurately control the defoaming process and ensure that appropriate measures can be taken in different foam situations. Each abnormal power gear corresponds to a specific defoaming process, which means that the equipment can take different defoaming measures according to the severity of different foam amounts. This targeted strategy helps to improve the defoaming efficiency and effect. By designing different defoaming processes for different abnormal power gears, the equipment can flexibly respond to various foam situations, whether it is mild, moderate or heavy foam, it can be effectively handled. By taking different defoaming measures at different power gears, the foam can be removed more quickly, thereby improving the dehydration efficiency and shortening the entire washing cycle. At the same time, taking different defoaming measures at different power gears can reduce the entanglement of clothes and overload of equipment caused by excessive foam, thereby protecting the texture of clothes and extending the service life of the equipment.

[0078] That is, the fabric processing device in the embodiment of the present application can intelligently select the corresponding defoaming process according to the actual power value. This adaptive adjustment mechanism makes the device more intelligent and able to cope with different washing challenges.

[0079] Furthermore, in some possible implementations,

[0080] In the first defoaming process, the drum motor is controlled to rotate at a speed of v1, and the spray device is controlled to be turned on for a preset time t1, where v1 is between 200 rpm and 300 rpm, and t1 is between 60s and 120s;

[0081] In the second defoaming process, the drum motor is controlled to rotate at a speed of v2, and the spray device is controlled to be turned on for a preset time t2, where v2 is between 100 rpm and 150 rpm, and t1 is between 150s and 210s;

[0082] In the third defoaming process, the drum motor is controlled to rotate at a speed of v3, and the spray device is controlled to open for a preset time t3, where v3 is between 40rpm and 80rpm, and t1 is between 240s and 300s.

[0083] In the embodiment of the present application, by setting a specific motor speed and spraying time for each defoaming process, the defoaming process can be precisely controlled to ensure that the best defoaming effect can be achieved under different foam conditions. The parameter settings of different defoaming processes take into account the severity of different foam amounts. For example, as the amount of foam increases, the motor speed decreases and the spraying time increases, which helps to handle more foam more effectively. By adjusting the motor speed and spraying time, the defoaming efficiency can be improved. When there is a lot of foam, a lower speed and a longer spraying time help to remove the foam more thoroughly. In each defoaming process, the reasonable setting of the motor speed and spraying time helps to reduce unnecessary energy consumption. For example, when there is less foam, a higher speed and a shorter spraying time can reduce energy waste. In addition, by adjusting the motor speed and spraying time in different defoaming processes, the entanglement of clothes and the overload of the equipment caused by excessive foam can be reduced, thereby protecting the texture of the clothes and extending the service life of the equipment and the service life of the drum motor.

[0084] Furthermore, in some possible implementations, the control method further includes:

[0085] In the current defoaming process, the spray device is controlled to be turned on or off according to the change of the water level in the barrel.

[0086] In the embodiment of the present application, during the defoaming process, by controlling the opening or closing of the spray device according to the changes in the water level in the barrel, it is possible to intelligently determine whether the drainage of the equipment is smooth. Specifically, if the water level in the barrel becomes abnormally high, the equipment may not be draining smoothly. At this time, the spray device can be temporarily closed and reopened after the water level drops.

[0087] Specifically, in some possible implementations, controlling the opening or closing of the spray device according to the change in the water level in the drum includes:

[0088] Obtain the water level value F in the drum before the defoaming process is started and the water level value F1 in the drum after the defoaming process is started, and obtain the water inlet flow value H of the spray device after the defoaming process is started;

[0089] Calculate the difference X between H and F and the difference X1 between H and F1, compare X and X1, and control the opening or closing of the spray device based on the comparison result of X and X1.

[0090] That is, in the embodiment of the present application, by measuring the water level value (F and F1) in the cylinder and the water inlet flow value H of the spray device before and after the defoaming process is started, the changes in foam and water level can be accurately monitored. By calculating the difference X between H and F (indicating the foam calibration value) and the difference X1 between H and F1 (indicating the water level change during the spraying period), it is possible to intelligently determine whether the drainage is smooth. If the comparison result of X1 and X shows that the drainage is not smooth, the opening or closing of the spray device can be adjusted in time. That is, based on the comparison result of X and X1, the opening or closing of the spray device can be intelligently controlled to optimize the defoaming effect. For example, if there is too much foam and the drainage is not smooth, the spray device can be temporarily turned off and then turned on again after the water level drops.

[0091] Furthermore, in some possible implementations, controlling the opening or closing of the spray device based on the comparison result of X and X1 includes:

[0092] If X1 is less than or equal to k times X, the sprinkler is controlled to be closed, and when X1 is greater than k times X, the sprinkler is controlled to be opened again;

[0093] The value of k is between 0 and 1.

[0094] In the embodiment of the present application, by introducing the proportional factor k, the opening and closing of the spray device can be controlled more accurately. When X1 is less than or equal to k times X, it indicates that there is too much foam and drainage is poor, and the spray device is turned off at this time; when X1 is greater than k times X, it indicates that the drainage situation has improved, and the spray device is turned on again at this time. By intelligently controlling the spray device based on the comparison results of X and X1, the defoaming effect can be optimized. Pausing spraying when there is too much foam helps to avoid further increasing the amount of foam; reopening spraying after drainage improves helps to continue defoaming. This avoids continuing to spray water when drainage is poor, thereby reducing unnecessary waste of water resources.

[0095] That is, in the embodiment of the present application, by introducing the proportional factor k, an intelligent adjustment mechanism is provided, which enables the equipment to dynamically adjust the operation of the spray device according to the actual foam situation (reflected by the power gear) and the setting of the defoaming process (motor speed and spraying time) to achieve the best defoaming effect.

[0096] Furthermore, in some possible implementations, the control method further includes:

[0097] Determine the value of k based on the specific defoaming process corresponding to the abnormal power level;

[0098] The higher the defoaming degree, the larger the k value corresponding to the defoaming process.

[0099] In the embodiment of the present application, by determining the value of k according to the degree of defoaming in the defoaming process, a more targeted control strategy can be provided for each defoaming process. This means that for more severe foaming situations, the device will take more proactive measures to control the spray device.

[0100] Furthermore, in some possible implementations, the power gears of the fabric processing device include a first power gear at a normal power gear, and a second power gear, a third power gear, and a fourth power gear at an abnormal power gear;

[0101] The defoaming process includes a first defoaming process corresponding to the second power gear, a second defoaming process corresponding to the third power gear, and a third defoaming process corresponding to the fourth power gear;

[0102] The value of k is determined according to the specific defoaming process corresponding to the abnormal power level, including:

[0103] When the defoaming process is the first defoaming process, the value of k is 0.1-0.3;

[0104] When the defoaming process is the second defoaming process, the value of k is 0.4-0.6;

[0105] When the defoaming process is the third defoaming process, the value of k is 0.7-0.9.

[0106] Specific, combined Figure 2 and Figure 3 The control logic of the dehydration process of the fabric processing device in the embodiment of the present application is specifically described:

[0107] Set the device's motor power level to L1, L2, L3, or L4. 0 ≤ L1 < 200, 200 ≤ L2 < 300, 300 ≤ L3 < 400, and 400 ≤ L4, where 200, 300, and 400 correspond to units of power. During the spin cycle, collect motor power values ​​in real time. After the speed reaches 400 rpm and remains stable, record the highest motor power value (W) during this period. If W is within the L1 power range, the washing machine is deemed to have no or minimal foam, and the spin cycle continues. If W falls into the L2, L3, or L4 range, reduce the drum speed to 0 and initiate a rapid defoaming process.

[0108] When W is in the power range L2, the first defoaming process, lasting t1, begins: the drum motor is controlled to increase its speed to v1, and the drain pump is simultaneously activated. After the speed stabilizes, the spray valve opens to spray water into the drum, draining the foam through the flowing water. The value of t1 is 60s to 120s, and the value of v1 is 200rpm to 300rpm.

[0109] When W is in the power range of L3, the second defoaming process, lasting t2, begins: the motor is controlled to increase its speed to v2, and the drain pump is simultaneously activated. After the speed stabilizes, the spray valve opens to spray water into the tub, discharging the foam through the flowing water. The value of t2 is 150s to 210s, and the value of v2 is 100rpm to 150rpm.

[0110] When W is in the power range of L4, the third defoaming process, lasting t3, begins: the motor is controlled to increase its speed to v3, and the drain pump is simultaneously activated. After the speed stabilizes, the spray valve opens to spray water into the tub, discharging the foam through the flowing water. The value of t3 is 240s to 300s, and the value of v3 is 40rpm to 80rpm.

[0111] As can be seen, the larger the actual power value W of the drum motor at 400 rpm, the longer the subsequent defoaming process takes, and the lower the speed during the defoaming process. This setting is partly due to the fact that the foam in the washing machine drum creates resistance to the rotation of the drum. The higher the speed, the more obvious the resistance, and the greater the force required to rotate the washing machine, which is reflected in the higher power. Therefore, the larger the actual power value W, the more foam there is in the drum. If the speed is too high at this time, it will lead to increased power, motor heating, and a safety hazard.

[0112] When the rapid defoaming process is completed, the normal dehydration process continues. At the same time, the real-time power value of the drum motor continues to be collected, and the rapid defoaming judgment is performed based on the highest value W. If the judgment conditions are met, the rapid defoaming process continues to ensure that the washing machine can complete the dehydration process normally.

[0113] Furthermore, a flow meter can be installed on the sprinkler. When the sprinkler is turned on, the flow meter records the real-time flow rate value H and the water level value F in the cylinder before the sprinkler is turned on. The foam calibration value X = HF is obtained, where H is the real-time value and F is a fixed value (only the water level value before the sprinkler is turned on is recorded). During the sprinkler, F1 is also recorded, where F1 is the real-time water level value.

[0114] During the spraying process, if H-F1 ≤ 0.3X during the first defoaming cycle, it is determined that drainage is blocked due to excessive foam. If H-F1 ≤ 0.6X during the second defoaming cycle, it is determined that drainage is blocked due to excessive foam. If H-F1 ≤ 0.8X during the third defoaming cycle, it is determined that drainage is blocked due to excessive foam. At this time, the water inlet valve is controlled to close, while the drainage device remains open and the speed remains unchanged. When H-F1 ≥ 0.3X, H-F1 ≥ 0.6X, or H-F1 ≥ 0.8X, spraying is resumed.

[0115] It's worth noting that the difference between the flow rate H and the water level F (or F1) can reflect the drainage situation. The flow rate reflects the amount of water entering, while the water level reflects the amount of water in the drum. When the flow rate remains unchanged (i.e., the water inflow is stable), if the water level rises, it means that the water in the drum is increasing, which means that the drainage is not smooth.

[0116] It can be understood that when the difference between the flow value and the water level value is smaller, the more water accumulates in the cylinder, and when the difference between the flow value and the water level value is larger, the less water accumulates in the cylinder.
