[0055] In order to make the objects, technical solutions and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the application.

[0056] Fig. 1 is a flowchart of a control method of a clothes processing device according to the application, comprising:

[0057] S101, determine that the clothes treatment device completes dehydration.

[0058] S102, control the inner tub of the clothes treatment device to rotate, and acquire a load distribution state.

[0059] S103, determine to execute a scattering program based on the load distribution state satisfying a preset distribution state.

[0060] Specifically, the clothes treatment device in the embodiments of the present application can refer to a washing and drying all-in-one machine and the like, which has cleaning, dehydration and drying functions. The load can be clothes and the like to be cleaned.

[0061] The load distribution state represents the distribution of the load in the inner tub, for example, whether the load is wall-hugging, entangled, knotted, bunched, or uniformly distributed, and can freely fall in the inner tub along with the rotation of the inner tub.

[0062] When the load distribution state is uneven, bunched and wall-hugging, the drying effect is poor, which affects the user's experience. When the load distribution state is uniform, and the load can freely fall and change position along with the rotation of the inner tub, the drying effect is good.

[0063] Based on the above background, before determining that the dehydration is completed and executing the drying program, the embodiments of the present application control the inner tub of the clothes treatment device to rotate to acquire the load distribution state. When the load distribution state satisfies the preset distribution state, the scattering program is executed to scatter the load, which is beneficial to improve the drying effect in the drying process. The preset distribution state can represent that the load is in the state of entanglement and wall-hugging.

[0064] In some embodiments, S102 includes:

[0065] Control the inner tub of the clothes treatment device to rotate at a target speed.

[0066] Determine the load distribution state based on at least two collected inner tub rotation parameters.

[0067] The inner tub rotation angles corresponding to the adjacent two collected inner tub rotation parameters differ by 360 degrees.

[0068] The target speed can be the inner tub rotation speed in the clothes drying process, for example, it can be 90 revolutions per minute, so that the inner tub rotates at the target speed, which can better reflect the load distribution state of the clothes treatment device in the drying process.

[0069] Fig. 2 is a schematic diagram of the inner tub state provided by the embodiments of the present application. In Fig. 2, a mark point P0 is specially marked, which is an arbitrary specific position point on the inner tub. The mark point P0 is only used to more clearly and explicitly show the position state of the inner tub, and G represents the load.

[0070] As shown in FIG. 2, in (a) of FIG. 2, the identification point P0 is located at the lowermost position of the inner tub, and in (b) and (c) of FIG. 2, the identification point P0 is still located at the lowermost position of the inner tub. If the load G is in the wall-adhering state, the relative position of the load G to the inner tub remains unchanged, and thus in (b) of FIG. 2, the load G is still in the same position as in FIG. 1. If the load G is not in the wall-adhering state, the load G falls during the rotation of the inner tub, and thus the position of the load G can change after the inner tub rotates 360 degrees, and thus in (c) of FIG. 2, the load G is in a different position from that in FIG. 1.

[0071] As can be understood from (b) and (c) of FIG. 2, the load G in the inner tub can have an impact on the inner tub rotation parameter, and the inner tub rotation parameter can be different when the load G is in different positions, and the inner tub rotation parameter is the same or close to the same when the load G is in the same position. Therefore, the embodiments of the present application can accurately determine the load distribution state based on the inner tub rotation parameters collected at least twice.

[0072] In some embodiments, the load distribution state includes a load distribution coefficient.

[0073] Based on the inner tub rotation parameters collected at least twice, the load distribution state is determined.

[0074] Based on the inner tub rotation parameters collected at least twice, the load distribution coefficient is determined.

[0075] The load distribution coefficient is positively correlated with the fluctuation of the inner tub rotation parameter.

[0076] Based on the reference to FIG. 2 and the corresponding embodiments thereof, the inner tub rotation parameter can be different when the load G is in different positions, and the inner tub rotation parameter is the same or close to the same when the load G is in the same position. Therefore, the present application can determine the load distribution coefficient based on the inner tub rotation parameter, and the load distribution coefficient is positively correlated with the fluctuation of the inner tub rotation parameter.

[0077] The fluctuation of the inner tub rotation parameter refers to the difference between at least two groups of inner tub rotation parameters when the inner tub is in the same position, for example, the difference between two groups of inner tub rotation parameters when the identification point P0 is in the same lowermost position. The greater the difference, the greater the fluctuation of the inner tub rotation parameter.

[0078] Based on the above embodiments in FIG. 2, it can be understood that when the load G is in the wall-adhering state, the fluctuation of the inner tub rotation parameters collected at least twice is small, and thus the load distribution coefficient is also small. When the load G is not in the wall-adhering state, the fluctuation of the inner tub rotation parameters collected at least twice is large, and thus the load distribution coefficient is also large.

[0079] Based on the above scheme, the embodiments of the present application can determine whether the clothes are wall-hung through the load distribution coefficient, and further determine whether the preset distribution state is met. In the case of meeting the preset distribution state, the scattering program is executed to scatter the load, which is beneficial to improve the drying effect.

[0080] In some embodiments, the load distribution coefficient is determined based on at least two collected inner drum rotation parameters, comprising:

[0081] The load distribution coefficient is determined based on the change rate of at least one set of adjacent two collected inner drum rotation parameters.

[0082] The change rate of the adjacent two collected inner drum rotation parameters is:

[0083] Wherein, X represents the load distribution coefficient, and A1 and A2 are the adjacent two collected inner drum rotation parameters.

[0084] Specifically, as described in the above embodiments, when the load is in the wall-hung state, the inner drum rotation parameter fluctuates less, and when the load is in the non-wall-hung state, the inner drum rotation parameter fluctuates more. Therefore, the embodiments of the present application can determine the change rate of the adjacent two collected inner drum rotation parameters based on the above method, and the change rate can be the load distribution coefficient.

[0085] As can be seen from the formula of the above change rate X, the smaller X is, the more serious the load wall-hung phenomenon is, and vice versa, the larger X is, the more slight the load wall-hung phenomenon is.

[0086] Therefore, the embodiments of the present application can accurately determine the load distribution state, i.e., whether the load is wall-hung and the degree of load wall-hung, according to the value of the change rate X.

[0087] In some other embodiments, the change rate of the inner drum rotation parameter can also be determined in other ways, for example Or the variance, standard deviation, etc. of at least two sets of inner drum rotation parameters is calculated, which is not described here.

[0088] In some embodiments, the inner drum rotation parameter includes at least one of the motor measured rotation speed, the motor measured torque and the motor measured power.

[0089] Specifically, the motor measured rotation speed, the motor measured torque and the motor measured power will not be in a completely unchanged state during the rotation of the inner drum, but will be constantly changing based on the load distribution state in the inner drum.

[0090] For example, the inner tub measured rotating speed, FIG. 3 is a kind of inner tub rotating speed curve schematic diagram provided in the embodiment of the application. In FIG. 3, the horizontal axis t represents time, unit can be s, the vertical axis w represents rotating speed, unit can be rpm, i.e. revolution per minute. Inner tub measured rotating speed changes with the change of the position of the center of gravity of load in inner tub. As shown in FIG. 3, in the case of load completely adhering to wall, when the position of the center of gravity of load is at the lowermost of inner tub, motor measured rotating speed is maximum, when the position of the center of gravity of load is at the uppermost of inner tub, motor measured rotating speed is minimum, as a whole, it presents the shape of approximate sine wave, w m That is, it can be the rotating speed of inner tub when the position of the center of gravity of load is at three o'clock direction in inner tub, in the process that load rotates from three o'clock direction clockwise to six o'clock direction, the rotating speed of inner tub gradually increases, when the position of the center of gravity of load is at six o'clock direction in inner tub, the rotating speed of inner tub reaches maximum, and then continues to decrease. In some embodiments, w m It can also be the target rotating speed in the above embodiment. The change principle of motor measured torque and motor measured power is similar to the change principle of motor measured rotating speed. t2 and t6 in FIG. 3 correspond to inner tub measured rotating speed when the position of the center of gravity of load is at the lowermost of inner tub. In the case of load adhering to wall, the rotating speed corresponding to t2 and t6 is the same or close to the same. t1-t12 are shown in FIG. 3, and the curve shown in FIG. 3 can be understood that the rotating speed at t1, t5 and t9 time is the same or close to the same in the case of load adhering to wall, the rotating speed at t2, t6 and t10 time is the same or close to the same in the case of load adhering to wall, the rotating speed at t3, t7 and t11 time is the same or close to the same in the case of load adhering to wall, and the rotating speed at t4, t8 and t12 time is the same or close to the same in the case of load adhering to wall.

[0091] And if load does not adhere to wall, the relative position of load and inner tub changes after inner tub rotates 360 degrees, then inner tub measured rotating speed is different from inner tub measured rotating speed before inner tub rotates 360 degrees, and the change rate is large.

[0092] Therefore, based on the above scheme, the embodiment of the application can accurately determine the load distribution coefficient based on at least one of motor measured rotating speed, motor measured torque and motor measured power, and then determine the load distribution state in inner tub, i.e. whether load adheres to wall and whether load adhering to wall is serious.

[0093] In some embodiments, the inner tub rotating parameter includes motor measured power. Based on at least two collected inner tub rotating parameters, the load distribution coefficient is determined, including:

[0094] The first motor power consumption is determined based on the motor measured power collected in the preset inner tub rotating angle range in the first inner tub rotating period.

[0095] The second motor power consumption is determined based on the motor measured power collected in the preset inner drum rotation angle range in the second inner drum rotation period.

[0096] The load distribution coefficient is determined based on the first motor power consumption and the second motor power consumption.

[0097] The fluctuation of the first motor power consumption and the second motor power consumption is positively correlated with the load distribution coefficient. The starting angle of the preset inner drum rotation angle range in the first inner drum rotation period is the same as the starting angle of the preset inner drum rotation angle range in the second inner drum rotation period. The ending angle of the preset inner drum rotation angle range in the first inner drum rotation period is the same as the ending angle of the preset inner drum rotation angle range in the second inner drum rotation period.

[0098] Specifically, the motor consumes certain power consumption in the process of rotating the inner drum. Due to the influence of the load in the inner drum, the rotation speed, torque, power and the like of the inner drum may be different when the center of gravity of the load is located at different positions, thereby causing the motor to consume different power consumption in the process of rotating the inner drum.

[0099] FIG. 4 is another schematic diagram of the state of the inner drum provided by an embodiment of the present application. The inner drum can have one rotation period for each 360 degrees of rotation.

[0100] As shown in (a) of FIG. 4, the position of the identification point P0 is the position of the starting angle of the preset inner drum rotation angle range in the first inner drum rotation period, and the position of the identification point P1 is the position of the ending angle of the preset inner drum rotation angle range in the first inner drum rotation period. In the process of rotating from the starting angle to the ending angle, the first motor power consumption can be determined based on the motor measured power.

[0101] As shown in (b) of FIG. 4, the position of the identification point P0 is the position of the starting angle of the preset inner drum rotation angle range in the second inner drum rotation period, and the position of the identification point P1 is the position of the ending angle of the preset inner drum rotation angle range in the second inner drum rotation period. In the process of rotating from the starting angle to the ending angle, the second motor power consumption can be determined based on the motor measured power.

[0102] In the (c) diagram of FIG. 4, the position of the identification point P0 is the position of the starting angle of the preset inner drum angle range in the second inner drum rotation period, and the position of the identification point P1 is the position of the ending angle of the preset inner drum angle range in the second inner drum rotation period. The (c) diagram of FIG. 4 and the (b) diagram of FIG. 4 both correspond to the second inner drum rotation period, but the difference is that the (b) diagram of FIG. 4 illustrates the state of the inner drum in the case of the load G adhering to the wall, and the (c) diagram of FIG. 4 illustrates the state of the inner drum in the case of the load G not adhering to the wall. As can be understood from the comparison between the (b) diagram and the (c) diagram of FIG. 4, because the load G does not adhere to the wall in the (c) diagram of FIG. 4, the position of the center of gravity of the load G changes, and in the process of the inner drum rotating from the starting angle to the ending angle, the motor measured power corresponding to the (b) diagram of FIG. 4 is the same as or close to the motor measured power corresponding to the (a) diagram of FIG. 4, and the motor measured power corresponding to the (c) diagram of FIG. 4 is different from the motor measured power corresponding to the (a) diagram of FIG. 4.

[0103] Further, because the motor measured powers are different, in the process of rotating from the starting angle to the ending angle, the first motor power consumption in the first inner drum rotation period is different from the second motor power consumption in the second inner drum rotation period. The smaller the difference between the first motor power consumption and the second motor power consumption, the more serious the load adhesion phenomenon.

[0104] Therefore, the embodiments of the present application can determine the load distribution coefficient by the first motor power consumption and the second motor power consumption.

[0105] In some embodiments, the load distribution coefficient is determined based on the following manner:

[0106] wherein i is 1 or 2. K represents the load distribution coefficient, B i represents the i-th motor power consumption. P(t) represents the motor measured power collected in the preset inner drum rotation angle range.

[0107] Continuing to refer to FIG. 4 and the corresponding embodiments thereof, the more serious the load G adhesion phenomenon, the smaller the difference between the first motor power consumption and the second motor power consumption. Therefore, the distribution coefficient can be determined based on the fluctuation degree between the first motor power consumption and the second motor power consumption. The first motor power consumption and the second motor power consumption can be obtained by integrating the motor measured power, and then the load distribution coefficient can be determined by the above formula . The smaller the load distribution coefficient, the more serious the load G adhesion phenomenon.

[0108] In summary, the embodiments of the present application can accurately determine the load distribution coefficient based on the motor measured power based on the above scheme, and then determine the load distribution state.

[0109] In some embodiments, based on the load distribution state satisfying a preset distribution state, it is determined to execute a scattering program, including:

[0110] Based on the load distribution coefficient being less than or equal to the first threshold value, water and / or air is introduced into the inner tub, and the scattering program is executed.

[0111] Specifically, if the load distribution coefficient is less than or equal to the first threshold value, it can be indicated that the load adhesion phenomenon is serious, and at this time the clothes treatment apparatus can be controlled to inject water and / or air into the load in the inner tub.

[0112] For water injection and / or air introduction to the load, the core idea is to apply an auxiliary external force to the load to make the load more easily fall off the barrel wall of the inner tub to achieve the purpose of scattering.

[0113] For water injection to the load, it can also wet the load to reduce the adsorption force between the load and the barrel wall of the inner tub, so that the load is more easily detached from the barrel wall of the inner tub to achieve the purpose of scattering.

[0114] In this process, cold air can be blown to the load, or hot air can be blown to the load, but generally hot air is preferred. Because blowing hot air to the load can achieve the effect of raising the temperature of the load itself, thereby improving the drying effect in the subsequent process.

[0115] In this process, the amount of water injected to the load needs to be controlled according to the situation, and the amount of water should not be too much or too small. Too much water injection can directly affect the drying effect in the subsequent drying process, and too little water injection cannot achieve the ideal purpose of making the load more easily fall off the barrel wall of the inner tub. The embodiments of the present application can determine the amount of water injection based on the weight, type, and number of the load, etc. For example, if the load is only one shirt, the amount of water injection can be tens of milliliters, and if the load is a coat, the amount of water injection can be appropriately increased.

[0116] For the scattering program, the embodiments of the present application can control the inner tub to rotate in the forward and reverse directions, for example, first rotate at 45 revolutions per minute for 5 seconds in the forward direction, then stop rotating for 3 seconds, then rotate at 45 revolutions per minute for 5 seconds in the reverse direction, then stop rotating for 3 seconds, and then repeat the above process until a set number of times is repeated.

[0117] In some embodiments, during the execution of the scattering program, the first rotation direction of the inner tub can be opposite to the direction of the previous rotation of the inner tub to achieve a better scattering purpose.

[0118] In summary, the embodiments of the present application can achieve the purpose of scattering the load based on the above-mentioned scheme in the case of serious load adhesion phenomenon.

[0119] In some embodiments, it further includes:

[0120] perform the scattering procedure based on the load distribution coefficient being greater than the first threshold value and less than or equal to a second threshold value.

[0121] The second threshold value is greater than the first threshold value.

[0122] If the load distribution coefficient is greater than the first threshold value and less than or equal to the second threshold value, it indicates that the load has a wall sticking phenomenon, but the wall sticking phenomenon is light, so the scattering procedure can be directly performed to achieve the purpose of scattering the load.

[0123] In some embodiments, the method further includes performing a weighing operation based on the load distribution coefficient being greater than the second threshold value.

[0124] Specifically, if the load coefficient is greater than the second threshold value, it indicates that the load is not in a wall sticking state, and the weighing operation can be performed. The weighing operation is used to determine the weight of the clothes, and specific drying parameters are used based on the weight of the clothes.

[0125] In some embodiments, the method further includes:

[0126] performing the weighing operation based on the number of times of performing the scattering reaching a preset number of times.

[0127] Specifically, in the embodiments of the present application, after the scattering procedure is performed again, the above S102 can be returned to determine the scattering effect. If the scattering effect is poor, the scattering is performed again to improve the scattering effect.

[0128] If the number of times of scattering reaches the preset number of times, it indicates that the scattering procedure of the clothes processing device itself cannot achieve the purpose of scattering the load, and the weighing operation can be directly performed to determine the weight of the load.

[0129] In some embodiments, the method further includes:

[0130] determining the drying parameters based on the weighing result.

[0131] Specifically, the embodiments of the present application can determine the drying parameters based on the weighing result, i.e., the weight of the load. Different weighing results correspond to different drying parameters. The drying parameters can at least include drying temperature, drying time, drying speed, etc., which are not described in detail here.

[0132] The embodiments of the present application can determine different drying parameters based on different weighing results to achieve better drying effect.
