Typically, the washing machine corrects this imbalance by adding water. However, this method wastes a significant amount of water and electricity, and consequently extends the overall washing time. Summary of the Invention

[0004] To address the aforementioned technical problems, the first aspect of this invention provides a dehydration control method for a garment processing device, wherein the garment processing device is equipped with a dehydration correction mode, and the dehydration control method includes:
[0005] During the dehydration stage, the garment processing equipment is monitored for any collisions with the drum. If a collision occurs, the dehydration correction mode is activated.
[0006] In the spin-drying correction mode, determine the degree of tangling of clothes and the weight of clothes in the drum;
[0007] Based on the degree of tangling of the clothes and the weight of the clothes in the drum, a corresponding imbalance correction plan is determined to balance the clothes in the drum.
[0008] Further, optionally, the degree of tangling of the clothes and the weight of the clothes inside the drum are determined, including:
[0009] Before the dehydration correction mode, before water is injected into the garment processing equipment, the motor is controlled to rotate in both directions, the corresponding motor pulse value N0 is recorded, and the weight M0 of the tubular underwear is determined based on N0.
[0010] In the spin-drying correction mode, the motor is controlled to rotate in both directions, and the corresponding motor pulse value N is recorded. The degree of tangling of clothes is determined based on the difference ΔN between N0 and N before washing, where the difference is proportional to the degree of tangling of clothes.
[0011] Further, optionally, a corresponding imbalance correction scheme can be determined based on the degree of tangling of the clothes and the weight of the clothes inside the drum, including:

[0013] Further, optionally, a corresponding imbalance correction scheme can be determined based on the degree of tangling of the clothes and the weight of the clothes inside the drum, including:
[0014] The intensity and duration of the balanced washing cycle are determined based on the degree of tangling and the weight of the clothes in the drum; among which,
[0015] The intensity of the balanced washing cycle is directly proportional to the degree of tangling of the clothes and the weight of the clothes in the drum;
[0016] The washing time is directly proportional to the degree of tangling of clothes and the weight of clothes in the drum.
[0017] Further, optionally, after the balanced washing program is completed, the control method further includes:
[0018] The degree of tangling of the clothes is reassessed, and a corresponding dehydration plan is determined based on the degree of tangling and the weight of the clothes in the drum to continue the dehydration process.
[0019] Further, optionally, the degree of clothing tangling is reassessed, and a corresponding dehydration scheme is determined based on the degree of tangling and the weight of the clothing in the drum, including:

[0021] Find the dehydration program corresponding to the pulse difference ΔN1 and weight M0 from the table comparing pulse difference and weight of tubular clothing with dehydration program.
[0022] Further, optionally, a corresponding dehydration scheme can be determined based on the degree of tangling of the clothes and the weight of the clothes in the drum, including:
[0023] The appropriate spin cycle and spin time are determined based on the degree of tangling of the clothes and the weight of the clothes inside the drum.
[0024] The intensity of the dehydration cycle is inversely proportional to the degree of tangling of the clothing;
[0025] The spin cycle time is directly proportional to the weight of the clothes inside the drum.

[0030] If not, control the dehydration process through a dehydration correction mode.
[0031] Further, optionally, the dehydration control method also includes:
[0032] When entering the water storage correction mode, record the number of times this mode is entered, b.
[0033] Determine whether b satisfies b≥B, where B is the second preset value;
[0034] If so, an alarm will sound if dehydration fails.
[0035] If not, the dehydration process is controlled through a water storage correction mode.
[0036] Alternatively, if dehydration is successful each time the dehydration correction mode or water storage correction mode is entered, the dehydration process can be exited.
[0037] A second aspect of the present invention provides a control device for an air conditioner, comprising one or more processors and a non-transitory computer-readable storage medium storing program instructions, wherein when the one or more processors execute the program instructions, the one or more processors are configured to implement the method according to any one of the first aspects.

[0048] To address the problem in related technologies where washing machines can only correct the imbalance of the washing drum through water storage during the spin-drying process, resulting in wasted water and electricity, this embodiment provides a spin-drying control method for a garment processing device, including drum washing machines, pulsator washing machines, etc., with a preferred embodiment being a pulsator washing machine.
[0049] The dehydration control method of this embodiment will be described below with reference to the accompanying drawings.
[0050] The garment processing equipment features a spin-drying correction mode, which replaces the traditional water-storage correction mode to correct imbalances in the garments within the drum. Figure 1 The dehydration control method includes steps S1 to S3, wherein:
[0051] S1, during the dehydration stage, monitor whether the garment processing equipment experiences a drum collision. If a drum collision occurs, enter the dehydration correction mode.
[0052] Specifically, taking a pulsator washing machine as an example, after detecting the signal of the impact bar, it enters the spin-drying correction mode, or after detecting the signal of the impact bar multiple times (e.g., 3 times) in a row, it enters the spin-drying correction mode.
[0053] S2, in the spin-drying correction mode, determines the degree of tangling of clothes and the weight of clothes in the drum;
[0054] Optionally, the degree of clothing tangling can be determined by monitoring the motor current. The weight of the clothes inside the drum can be the current load weight inside the drum or the net weight of the clothes themselves.
[0055] S3. Determine the corresponding imbalance correction scheme based on the degree of tangling of the clothes and the weight of the clothes in the drum, so as to balance the clothes in the drum.
[0056] Specifically, the heavier or more tangled the clothes, the more force the impeller needs to rotate to achieve a balanced washing effect. Therefore, determining the balancing scheme based on the degree of tangling and weight of the clothes can improve the balanced washing effect, thereby increasing the success rate of spin-drying.
[0057] The dehydration control method of this embodiment can, when a drum collision event is detected during the dehydration process of the clothing processing equipment, adopt different imbalance correction schemes based on the weight and degree of entanglement of the load. This solves the problem in related technologies where washing machines can only use water storage correction to achieve drum imbalance during the dehydration process, resulting in wasted water and electricity.
[0058] More preferably, step S2 includes S21 to S22, wherein:
[0059] S21, Before the dehydration correction mode and before water is injected into the garment processing equipment, control the motor to perform forward and reverse rotation, record the corresponding motor pulse value N0, and determine the weight M0 of the tubular underwear based on N0.
[0060] S22, in the spin-drying correction mode, the motor is controlled to rotate in both directions, and the corresponding motor pulse value N is recorded. The degree of tangling of clothes is determined based on the difference ΔN between N0 and N before washing, where the difference is proportional to the degree of tangling of clothes.
[0061] Specifically, before entering the spin-drying correction mode and before water is added to the laundry equipment, the motor is controlled to rotate in both directions. The motor pulse value N0 during these rotations is recorded. N0 can be the real-time motor pulse value or the average value of the motor pulses throughout the entire rotation process. The weight M0 of the laundry in the drum at that moment can be determined from the pulse value. Since the more severely the clothes are tangled, the greater the resistance the motor exerts on the washing machine's pulsator to overcome the rotation of the clothes, the smaller the motor pulse value. The motor pulse value N0 corresponding to the clothes at this moment is considered to indicate that the clothes are not tangled under this resistance. Subsequently, when the spin-drying correction mode is entered, the motor pulse value N is recorded again. The degree of tangling is determined by the difference in pulse values caused by the magnitude of the resistance to the rotation of the clothes before and after N0 - N = ΔN.
[0062] Optionally, the motor is controlled to rotate in both directions with a preset rotation-stop ratio and a preset cycle. The preset rotation-stop ratio and preset cycle are distinct from the actual washing cycle. In this embodiment, a preferred rotation sequence is 0.7s forward, 0.5s stop, 0.7s reverse, 0.5s stop, repeated 5 times.
[0063] Further optionally, in step S3, the corresponding imbalance correction scheme is determined based on the degree of tangling of the clothes and the weight of the clothes in the tub, including: looking up the imbalance correction scheme corresponding to the difference ΔN and the weight M0 from the comparison table of pulse difference and weight of clothes in the tub and imbalance correction scheme.
[0064] Specifically, the pulse difference is divided into different intervals to distinguish different degrees of clothing entanglement, and the clothing weight is divided into different intervals to distinguish different weight levels. That is, different combinations of clothing entanglement degree and different clothing weight levels can determine different balancing schemes. Table 1 shows the numerical balancing schemes corresponding to the pulse difference ΔN and load weight M0 in this embodiment. As shown in Table 1, the weight of the clothing is divided into 8 intervals, and the pulse difference is also divided into 8 intervals. Different combinations of pulse difference and clothing weight can yield 64 different balancing schemes.
[0065] Table 1
[0066]
[0067] Further, optionally, the imbalance correction scheme includes balancing the washing cycle and balancing the washing duration, wherein,
[0068] The intensity of the balanced washing cycle is directly proportional to the degree of tangling of the clothes and the weight of the clothes in the drum;
[0069] The washing time is directly proportional to the degree of tangling of clothes and the weight of clothes in the drum.
[0070] Specifically, in this embodiment, the balancing scheme is preferably determined by balancing washing time and balancing washing rhythm. The heavier the clothes, or the more tangled the clothes, the greater the force required for the impeller to rotate in order to achieve a balanced washing effect.
[0071] For example, the weight of the clothes in the drum is divided into eight different weight levels from M1 to M8 (the weight increases from M1 to M8). The eight different weight levels correspond to eight different balanced washing times. The balanced washing time corresponding to M1 is preferably 50 seconds. For each additional weight level, the balanced washing time increases by 10 seconds, and M8 is 120 seconds.
[0072] The balance washing cycle is different for different weights from M1 to M8. The balance washing cycle for M1 is 0.6 revolutions followed by 0.6 stops, and then the washing time increases by 0.1 seconds for each additional weight. For M8, it is 1.3 revolutions followed by 0.6 stops.
[0073] Generally, different pulse differences correspond to different washing intensities, with the washing time increasing by 0.1 seconds for each additional pulse level.
[0074] For weight M1, if the pulse difference is within the range of ≤ΔN1, the balance washing cycle is 0.6s rotation, 0.6s pause, and 50s washing time. If the pulse difference is within the range of ≥ΔN8, the balance washing cycle is 1.3s rotation, 0.6s pause, and 50s washing time.
[0075] For example, under weight M8, if the pulse difference is within the range of ≤ΔN1, the balance washing cycle is 1.3s rotation, 0.6s pause, and 120s washing time. If the pulse difference is within the range of ≥ΔN8, the balance washing cycle is 2.0s rotation, 0.8s pause, and 120s washing time.
[0076] Further optionally, after the balanced washing program is completed, the control method also includes S4:
[0077] S4. Re-determine the degree of clothing tangling, and determine the corresponding dehydration plan based on the degree of clothing tangling and the weight of the clothes in the drum to continue the dehydration process.
[0078] Specifically, the heavier or more tangled the clothes, the greater the eccentricity of the pulsator washing machine. If the spin speed is forcibly increased, the clothes may hit the machine and cause displacement. Therefore, in order to improve the success rate of spin drying, the spin drying program needs to be determined according to the weight and degree of tangling of the clothes.
[0079] Optionally, in step S4, the degree of clothing tangling is re-determined, and a corresponding dehydration scheme is determined based on the degree of tangling and the weight of the clothing in the drum, including steps S41 to S42, wherein:
[0080] S41, control the motor to perform forward and reverse rotation, record the corresponding motor pulse value N1, and determine the degree of clothing tangling based on the difference ΔN′ between N0 and N1 before washing;
[0081] S42, find the dehydration scheme corresponding to the pulse difference ΔN′ and weight M0 from the comparison table of pulse difference and weight of tubular clothing with dehydration scheme.
[0082] Specifically, after the imbalance correction scheme is executed, the motor rotates in both directions, and the detected motor pulse value is N1. The degree of clothing entanglement is determined based on the difference ΔN′ between the initial motor pulse value N0 and the detected motor pulse value N1. During dehydration, the pulse difference and the weight of the clothing in the tubing are compared with a dehydration scheme table, and the dehydration scheme corresponding to ΔN′ and M0 is determined. Table 2 shows the dehydration schemes corresponding to the pulse difference ΔN′ and the clothing weight M0. As shown in Table 2, this embodiment divides the clothing weight into 8 intervals and the pulse difference into 8 intervals, thus determining 64 different dehydration schemes, which can effectively improve the dehydration success rate.
[0083] Table 2
[0084]
[0085] Further optionally, the dehydration program includes a dehydration cycle time and a dehydration duration, wherein,
[0086] The intensity of the dehydration cycle is inversely proportional to the degree of tangling of the clothing;
[0087] The spin cycle time is directly proportional to the weight of the clothes inside the drum.
[0088] Specifically, the heavier or more tangled the clothes, the greater the eccentricity of the pulsator washing machine. If the spin speed is forcibly increased, the clothes may hit the machine body and cause displacement.
[0089] In this embodiment, the dehydration cycle and dehydration duration are preferably determined based on the values of the intervals where M0 and ΔN′ are located.
[0090] For example, the total dehydration time is generally defined to be different for different weights from M1 to M8. The total dehydration time for M1 is 4 minutes. Then, the total dehydration time increases by 30 seconds for each weight increment. The total dehydration time for M2 is 4 minutes and 30 seconds, and so on, with M8 being 7 minutes and 30 seconds.
[0091] Generally, different pulse differences result in different intervals. Generally, a higher degree of entanglement indicates a larger eccentricity, so an interval with a slow initial acceleration should be added.
[0092] Taking a fixed-frequency washing machine as an example:
[0093] For loads with a weight of M1 and a pulse difference within the range of ≤ΔN1, where the winding degree is low and the weight is light, the speed should be increased directly. The dehydration cycle is 6 seconds of rotation followed by 4 seconds of rest, repeated 6 times; continuous dehydration for 3 minutes.
[0094] For loads with low entanglement and high weight, such as M8 loads, and pulse differences within the range of ≤ΔN1, the speed is directly increased and the dehydration time is extended. The dehydration cycle is 6 seconds of rotation followed by 4 seconds of rest, repeated 6 times; continuous dehydration takes 6 minutes and 30 seconds.
[0095] For example, under weight M1, if the pulse difference is within the range of ≥ΔN8, the load with high entanglement and low weight will have a slow speed-up, and the dehydration cycle will be 2 seconds of rotation and 2 seconds of rest, 5 times; 6 seconds of rotation and 4 seconds of rest, 5 times; continuous dehydration for 3 minutes.
[0096] For loads with a weight of M8 and a pulse difference within the range of ≥ΔN8, the dehydration speed increases slowly. The dehydration cycle is 2 seconds of rotation followed by 2 seconds of rest, repeated 5 times; then 6 seconds of rotation followed by 4 seconds of rest, repeated 5 times. Continuous dehydration lasts 6 minutes and 30 seconds.
[0097] Further, optionally, combined Figure 2 , Figure 3 The garment processing equipment is equipped with a water storage correction mode, and the dehydration control method also includes:
[0098] When entering the dehydration correction mode, record the number of times this mode is entered, 'a'.
[0099] Determine whether a satisfies a≥A, where A is a first preset value; in this embodiment, A is preferably 3.
[0100] If so, enter the water storage correction mode and control the dehydration process through the water storage correction mode;
[0101] If not, control the dehydration process through a dehydration correction mode.
[0102] Further, optionally, combined Figure 3 Dehydration control methods also include:
[0103] When entering the water storage correction mode, record the number of times this mode is entered, b.
[0104] Determine whether b satisfies b≥B, where B is a second preset value; in this embodiment, B is preferably 3.
[0105] If so, an alarm will sound if dehydration fails.
[0106] If not, the dehydration process is controlled through a water storage correction mode.
[0107] Specifically, after detecting the signal of the impact rod, it enters the dehydration correction mode. If it still cannot dehydrate successfully after entering this mode a limited number of times, it enters the traditional water storage correction mode. If it still cannot dehydrate successfully after entering this mode a limited number of times, a dehydration failure alarm will be triggered.
[0108] Specifically, such as Figure 3 The number of spin-drying rotation corrections and water storage corrections is set to 3. The machine enters the spin-drying correction mode. The washing machine stops all loads. If this is the first time entering this mode, the default balanced washing cycle is preferred, typically 0.9s forward, 0.6s stop, 0.9s reverse, 0.6s stop, washing for 80s. The motor rotates in both directions to adjust the eccentricity of the clothes in the washing tub. If this is the Nth time (N > 1) entering this mode, the balanced washing scheme is determined based on the difference in pulse values ΔN and M0 from the previous cycle. After the balanced washing cycle is completed, the motor rotates in both directions, and the current motor pulse value is detected as ΔN′. The difference ΔN′ between the initial motor pulse value N0 and the newly detected motor pulse value N′ is used. To improve the spin-drying success rate, the spin-drying cycle is determined according to different weight loads M0 and ΔN′ values. A second aspect of the invention provides a control device for an air conditioner, comprising one or more processors and a non-transitory computer-readable storage medium storing program instructions, wherein when the one or more processors execute the program instructions, the one or more processors are configured to implement the method according to any one of the first aspects.
