[0002] With the development of society and the advancement of science and technology, more and more users have begun to use clothing processing equipment, including washing machines, to dry clothes. However, during the process of drying clothes, the clothes are often not stretched enough, resulting in low drying efficiency, long drying time and low drying uniformity. In addition, during the process of drying and caring for clothes, the wrinkle removal effect is often poor due to the low stretching of the clothes. Therefore, how to control the clothing processing equipment so that the clothes can be fully stretched during the drying process has become a key factor in reflecting the drying and caring effects of a clothing processing equipment.

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work falls within the scope of protection of the present application. For example, the control method of the clothing processing equipment in the embodiments provided in the present application can be applied to other clothing processing equipment such as washing and drying machines, shoe washing machines, drum washing machines, vertical washing machines and nursing machines. Such changes do not deviate from the principles and scope of the present invention.

[0051] First, the application scenarios to which this application is applicable are introduced. Research has found that with the development of society and the advancement of science and technology, more and more users have begun to use clothing processing equipment, including washing machines, to dry clothes. However, during the drying process, the clothes often do not stretch well, resulting in low drying efficiency, long drying time, and low drying uniformity. In addition, during the drying and care process of clothes, the wrinkle removal effect is often poor due to the low stretch of the clothes. Therefore, how to control the clothing processing equipment so that the clothes can be fully stretched during the drying process becomes a key factor in reflecting the drying and care effects of a clothing processing equipment.

[0052] Moreover, the movement states of the target clothing in the target clothing processing equipment are usually divided into three types: falling, unfolding and sticking to the wall. The force states and corresponding rotation speed requirements of these three states are different. In order to make the clothing finally reach the stretched state smoothly and avoid the wall-sticking state, it is necessary to accurately control the corresponding stable rotation speed and the process of reaching the rotation speed.

[0053] Based on this, the embodiments of the present application provide a clothing stretching control method, device and electronic device for a clothing processing device. The embodiments provided in the present application solve the problems of low drying efficiency, long drying time and low drying uniformity of the clothing processing device, and can achieve better unfolding of the clothes, thereby reducing the risk of wrinkles on the clothes.

[0054] See also Figure 1 , Figure 1 This is a flowchart of a method for controlling the stretching of clothes in a clothes processing device provided in an embodiment of the present application. Figure 1 As shown in , the clothing stretching control method for a clothing processing device provided in an embodiment of the present application includes the following steps:

[0055] S101, a stratification stage, controlling the clothes to be thrown at a low speed of the clothes processing drum and to reach a fluffy and stratified state.

[0056] In this step, the embodiment provided by the present application controls the clothes in the clothes processing drum to maintain the fluffy and stratified state until the first preset execution time threshold T1 when the clothes reach the fluffy and stratified state in the stratification stage, wherein it is assumed that the first preset execution time threshold T1 in the embodiment provided by the present application can be specific but not limited to 10s-30s, and the rotation speed range of the clothes processing drum in the stratification stage of the embodiment provided by the present application is 20rpm-50rpm.

[0057] Here, the embodiment provided in the present application determines the first preset speed acceleration corresponding to the clothing processing drum in the stratification stage and the first target speed corresponding to the clothing processing drum in the stratification stage based on the weight and / or material type of the clothing; then, according to the first target speed and the first preset speed acceleration, the clothing in the clothing processing drum is controlled to maintain a fluffy and stratified state until the first preset execution time threshold T1.

[0058] Among them, the first target speed in the embodiment provided in the present application is directly determined during the application process based on the diameter information of the clothing processing drum, the weight of the clothing and / or the material type of the clothing. However, in the data experiment stage, the first target speed is obtained through specific force analysis (specifically but not limited to centripetal force analysis in the embodiment provided in the present application).

[0059] In the above, it is assumed that the clothing processing device in the embodiment provided by the present application can be specifically a clothing processing device of various common specifications on the market, and according to the relationship between gravity and centripetal force, it can be known that clothes placed randomly into the clothing processing device, when the target speed of the clothing processing device directly increases from low to high, the clothes are often not easy to stretch out and directly enter a state of sticking to the wall. At this time, the clothes in the clothing processing device cannot achieve a good stretching effect. Therefore, the present application has found through a large number of experiments and corresponding experimental data that if the clothes are in a state of being thrown at a low speed, the movement trajectory of the clothes does not exceed the vertical central axis (critical state), and the clothes can achieve a fluffy and layered state. At this time, selecting a suitable preset speed acceleration to increase the speed can make the clothes unfold with the layers, and finally achieve a better complete stretching effect.

[0060] Therefore, it is assumed that the speed states in the embodiments provided in the present application include but are not limited to a fluffy stratified state at low speed, a wall-adhering state at high speed, and an unfolded state at high speed, wherein the state at low speed corresponds to the clothes being in the stratified stage, and the wall-adhering state at high speed and the unfolded state at high speed correspond to the clothes being in the unfolding stage.

[0061] In this way, when the clothes in the clothing processing drum are in the stratification stage, the embodiment provided in the present application can perform centripetal force analysis on the clothes based on the drum diameter information of the clothing processing equipment, the weight information of the clothes in the clothing processing equipment, and the position coordinates of the clothes in the fluffy and stratified state, determine the critical throwing angle of the clothes in the critical state of low-speed throwing, and then determine the first target rotation speed of the clothes in the stratification stage based on the critical throwing angle.

[0062] The embodiment provided in this application determines the first target rotation speed in the critical state of low-speed throwing of clothes through the following sub-steps:

[0063] Sub-step 1: Based on the cylinder diameter information of the clothing processing device and the weight information of the clothing inside the clothing processing device, the centripetal force analysis is performed on the clothing to determine the force relationship of the clothing in the critical state of low-speed throwing.

[0064] For the specific force analysis process of the embodiment provided in the present application, please refer to Figure 2 , Figure 2 FIG. 1 shows a schematic diagram of force analysis of clothing in a layered stage in a clothing stretching control method for a clothing processing device provided by the present application. Figure 2 As shown in the figure, the force analysis of the clothes in the stratification stage in the clothes processing equipment is carried out. Assuming that the clothes are thrown from a relatively low height and their landing point just reaches the vertical center axis below, the force relationship of the clothes in the critical state of low-speed throwing is specifically as follows:

[0065] mrω1 2 ≤mgcosα;

[0066]

[0067] Among them, m is used to represent the weight information of the clothes inside the clothes processing device; R is used to represent the cylinder diameter information of the clothes processing device; ω1 is used to represent the critical angular velocity of the clothes; and α is used to represent the critical throwing angle of the clothes.

[0068] Sub-step 2: determining the motion trajectory relationship of the clothing in the stratification stage based on the position coordinates of the clothing in the stratification stage.

[0069] In this step, please continue to Figure 2 , assuming the clothes are Figure 2 The specific coordinates of the scattering point under the established coordinates are:

[0070] (x0, y0)=(rsinα, rcosα);

[0071] Here, the clothes are Figure 2 The specific coordinates of the landing point at the critical point of low-speed throwing under the established coordinates are:

[0072] (x, y) = (0, -r);

[0073] At this point, the specific relationship of the movement trajectory of the clothes in the layered stage can be determined as follows:

[0074] x=x0-vtcosα;

[0075]

[0076] Here, x0 is used to represent the horizontal coordinate of the clothes in the clothes processing device at the throwing point; y0 is used to represent the vertical coordinate of the clothes in the clothes processing device at the throwing point; x is used to represent the horizontal coordinate of the clothes in the clothes processing device at the landing point; y is used to represent the vertical coordinate of the clothes in the clothes processing device at the landing point.

[0077] Sub-step 3: determining a critical throwing angle of the clothes in the stratification stage based on the force relationship and the motion trajectory relationship.

[0078] In this step, according to Figure 2 The determined force relationship expression and motion trajectory relationship expression (specifically, the force relationship of the clothes in the critical state of low-speed throwing, the position coordinates of the throwing point, and the position coordinates of the landing point) are jointly solved to calculate the critical throwing angle α = 60° of the clothes in the critical state of low-speed throwing.

[0079] At this time, the specific coordinates of the spreading point are determined as follows:

[0080] Sub-step 4: Determine the critical angular velocity of the clothes in the stratification stage based on the critical throwing angle.

[0081] Here, according to Figure 2 The position coordinates of the throwing point in the stratification stage are then determined to be the critical angular velocity of the clothing.

[0082] Sub-step 5: determining a first target rotation speed of the clothes in the stratification stage according to the critical angular velocity.

[0083] Here, since ω1=2πn;

[0084] Therefore, it can be determined that when different laundry processing apparatuses are in different drum diameter information, the first target rotation speed n1 of the laundry in the stratification stage is different.

[0085] In the above description, it is assumed that the first target speed n1 in the stratification stage in the embodiment provided in this application can be specifically but not limited to 20 rpm-50 rpm.

[0086] Here, for details, please see Figure 3 , Figure 3 A schematic diagram showing a clothing layering stage in a clothing stretching control method for a clothing processing device provided in the present application is shown.

[0087] S102, in the unfolding stage, the clothes are controlled to unfold at a high speed of the clothes processing drum and reach a fully unfolded wall-adhering state.

[0088] In this step, the embodiment provided by the present application controls the clothes in the clothes processing drum to maintain the fully unfolded and wall-adhered state until the second preset execution time threshold T2 when the clothes reach the fully unfolded and wall-adhered state in the unfolding stage, wherein T2 in the embodiment provided by the present application is set to 10s-30s.

[0089] Here, it is assumed that the embodiment provided in the present application first determines the weight and / or material type of the clothes; then, based on the weight and / or material type of the clothes, determines the first preset speed acceleration corresponding to the clothes processing drum in the stratification stage and the first target speed corresponding to the clothes processing drum in the stratification stage; finally, according to the second target speed and the second preset speed acceleration, controls the clothes in the clothes processing drum to maintain a fully unfolded wall-attached state until the second preset execution time threshold T2.

[0090] It is assumed that the second preset speed acceleration a2 in the embodiment provided in this application is set to 1 rpm / s-30 rpm / s.

[0091] Thus, when the speed state is specifically the expansion stage, the method for determining the second target speed includes the following sub-steps:

[0092] Sub-step 1: Based on the cylinder diameter information of the clothing processing device and the weight information of the clothing inside the clothing processing device, the centripetal force analysis is performed on the clothing to determine the unfolding angular velocity of the clothing in a uniform speed state.

[0093] In this step, when the rotation speed state of the clothes in the clothing processing device is specifically a uniform expansion state, the embodiment provided in the present application will re-analyze the centripetal force of the clothes based on the cylinder diameter information of the clothing processing device and the weight information of the clothes inside the clothing processing device, and re-determine the expansion angular velocity of the clothes.

[0094] Here, please refer to the specific force analysis process. Figure 4 , Figure 4 FIG. 1 shows a schematic diagram of force analysis of clothing in the unfolding stage in a clothing stretching control method for a clothing processing device provided by the present application, as shown in FIG. Figure 4 As shown in the figure, a force analysis is performed on the clothes in the unfolding stage of the clothes processing device. Assuming that the clothes are fully unfolded and rolling in the inner drum, the entire body can be regarded as being provided with only the centripetal force by gravity. The specific force analysis relationship is as follows:

[0095] mω2 2 r = mg;

[0096] Among them, m is used to represent the weight information of the clothes inside the clothes processing device; R is used to represent the cylinder diameter information of the clothes processing device; ω is used to represent the unfolding angular velocity of the clothes in the unfolding stage.

[0097] Therefore, the unfolding angular velocity of the clothing in the unfolding stage in the embodiment provided by this application can be specifically:

[0098]

[0099] Thus, when the unfolding angular velocity is equal to , it is determined that the clothes are in a completely unfolded state in the clothes treating device.

[0100] In the speed up, when the angular velocity is expanded It means that the gravity at this time is not enough to provide centripetal force, and the clothes are still supported by the wall of the tube, that is, the clothes gradually enter the wall-adhering state.

[0101] Sub-step 2: determining a second target rotational speed of the clothes in the unfolding stage according to the unfolding angular velocity.

[0102] In this step, since ω2=2πn;

[0103] Therefore, it can be determined that under different drum diameter information of different laundry processing devices, the second target rotation speed of the laundry in a uniform speed state can be specifically but not limited to 60 rpm-90 rpm.

[0104] See also Figure 5 , Figure 5 One of the schematic diagrams showing the clothes in a uniform speed state in a clothes stretching control method of a clothes processing device provided in the present application is shown. Figure 5 A simulation diagram showing a state in which the clothing is fully unfolded in the unfolding stage is shown.

[0105] See also Figure 6 , Figure 6 The second schematic diagram shows the clothes in the unfolding stage in the clothes stretching control method of the clothes processing equipment provided by the present application. Figure 6 A simulation diagram showing the state of clothing sticking to the wall at a constant speed is shown.

[0106] in, Figure 5 and Figure 6 The direction of the arrow in the figure indicates the direction of movement of the clothes during rotation.

[0107] Optionally, the stratified stage includes at least one low-speed stage, and each of the low-speed stages has a corresponding low target speed; wherein, when the stratified stage includes n low-speed stages running in chronological order, n≥2, and the speed relationship of the n low-speed stages is Vi-1≤Vi≤.Vi+1, n≥i+1≥2; and / or the expansion stage includes at least one high-speed stage, and each of the high-speed stages has a corresponding high target speed, wherein, when the expansion stage includes m high-speed stages running in chronological order, m≥2, and the speed relationship of the m high-speed stages is Vi-1≤Vi≤.Vi+1, m≥i+1≥2.

[0108] Here, the stratification stage in the embodiment provided by the present application includes more than just a low-speed stage, and the expansion stage in the embodiment provided by the present application also includes more than just a high-speed stage.

[0109] Among them, it is assumed that the embodiment provided in this application is not limited to the two-stage from n to m, but can also be specifically a multi-stage low-speed stage, for example, determining at least one n1, and then rising from 0 through the at least one n1 to the second target speed n2, so that the clothes reach a fully unfolded state.

[0110] Alternatively, it is assumed that the embodiment provided in the present application is not limited to the two-stage from n1 to m, but can also be specifically a multi-stage high-speed stage, for example, determining at least one m1, and then rising from 0 through the at least one m1 to the second target speed m2, so that the clothes reach a fully unfolded state.

[0111] Alternatively, it is assumed that the embodiment provided in the present application is not limited to the two-stage from n1 to m, but can also be specifically a multi-stage preset speed acceleration a, for example, determining at least one a1, and then rising from 0 through the at least one a1 to the second target speed m, so that the clothes reach a fully unfolded state.

[0112] Optionally, the stratification stage and the expansion stage are performed alternately and include at least two rotation speed increase processes.

[0113] Here, the two-stage implementation case provided by this application from the n low-speed throwing critical state stratification to the m uniform speed expansion state is the best preferred embodiment. In addition, the control method of the clothing processing equipment in the embodiment provided by this application is not limited to the two-stage from n to m, but can also be specifically an implementation process from n to m and then to n, which is repeated in a cycle and includes at least two speed increases.

[0114] See also Figure 7 , Figure 7 A schematic diagram showing a curve of angular velocity changing over time in a method for controlling the stretching of clothes in a clothes processing device according to an embodiment of the present application is shown. Figure 7 As shown, it is assumed that the angular velocity in the embodiment provided in the present application is specifically two-stage. First, when ω1, the clothes are in the stratified stage with low speed, and then when ω2, the clothes are in the fully expanded stage with high speed, where the angular acceleration is represented by β.

[0115] S102. Adjusting the operation strategy of the clothing processing device based on the target speed and the preset speed acceleration under the different speed states so that the clothing is fully unfolded in the clothing processing device, wherein the preset speed acceleration is determined according to the weight information of the clothing.

[0116] In this step, the embodiment provided by the present application starts to control the inner drum of the clothing processing device to rotate from stationary after determining the second target speed of the clothes in the uniform speed state and the first target speed of the clothes in the low-speed throwing critical state, until the running speed of the clothing processing device reaches the first target speed, controls the clothes to enter the low-speed throwing critical state, and after the clothes enter the low-speed throwing critical state, controls the clothes processing device to execute the low-speed throwing strategy according to the first target speed, and then when the first actual execution time of the clothes executing the low-speed throwing strategy meets the range of the first preset execution time threshold, accelerates the first target speed according to the preset speed acceleration until the running speed of the clothing processing device reaches the second target speed, determines that the clothes enter the uniform speed unfolding state, and when the clothes enter the uniform speed unfolding state, controls the clothes processing device to execute the uniform speed unfolding strategy on the clothes according to the second target speed.

[0117] Here, it is assumed that the first preset execution time threshold in the embodiment provided in the present application can be specific but not limited to T1=10s-30s, wherein the significance of T1 is to keep the clothes in this state so that they can be smoothly layered and unfolded when subsequently accelerated according to the preset speed acceleration.

[0118] In the above, it is assumed that after the clothes are in a uniform speed state, the embodiments provided by the present application can continue to select multiple implementation methods to perform post-drying, stretching and care for the clothes, specifically: (1) drying and caring for the clothes after unfolding them, so that the efficiency is greatly improved; (2) or when the second actual execution time of the clothes executing the uniform speed unfolding strategy meets the range of the second preset execution time threshold, the second target speed is decelerated according to the preset speed acceleration until the operating speed of the clothes processing device reaches the first target speed, and it is determined that the clothes enter the low-speed throwing critical state again, and the speed state conversion is repeated until the clothes are completely unfolded in the clothes processing device.

[0119] In the above, when the second preset speed acceleration a2 is small, the clothes often fall off after being unfolded, resulting in a poor final unfolding degree; when the preset speed acceleration is large, the number of revolutions increases too fast and the clothes fail to unfold and enter a wall-sticking state. Therefore, the selected value of the second preset speed acceleration a2 is greatly affected by the weight of the clothes. The heavier the clothes, the greater the preset speed acceleration is required to lift the clothes. Therefore, the preset speed acceleration in the embodiment provided in the present application can solve the problem of clothes falling off after being unfolded when the acceleration is too small and clothes sticking to the wall before being unfolded when the acceleration is too large, thereby improving the drying and care effects of the clothes.

[0120] Here, when the type of clothing is a common suit, it is assumed that a common suit can achieve a better unfolding effect through a preset speed acceleration of about 10 rpm / s; and when the type of clothing is a common shirt, a preset speed acceleration of about 3 rpm / s is required to achieve a fully unfolded state.
