[0049] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0050] Currently, washing machines are unable to adjust washing parameters during the washing, dehydration, and drying stages based on the movement of the laundry within the washing machine. Instead, they follow a fixed, pre-set washing method, resulting in poor washing and dehydration results. The various embodiments provided herein are intended to address at least one of these issues.

[0051] According to one embodiment of the present invention, a clothing processing drum is provided, wherein a plurality of pressure sensors are distributed along the circumference of the inner wall of the clothing processing drum for detecting the clothing pressure borne by different positions of the inner wall during the rotation of the clothing processing drum; an angle sensor is provided on the rotating shaft of the clothing processing drum for detecting the rotation angle of the clothing processing drum.

[0052] Optionally, in an implementation of this embodiment, a plurality of pressure sensors are evenly distributed along the circumference of the inner wall of the clothing treatment tub, which is conducive to more accurate detection of clothing pressure.

[0053] Optionally, in an implementation of this embodiment, a plurality of pressure sensors are evenly distributed along the axial direction of the inner wall of the laundry treatment tub, so as to increase the coverage of laundry pressure detection.

[0054] Optionally, in one implementation of this embodiment, the rotation of the laundry processing drum wall is divided into different spatial positions, and accordingly, the pressure sensor will also pass through different spatial positions during the rotation process. That is, in this embodiment, since the spatial position is fixed and the relative positional relationship between the pressure sensor and the laundry processing drum is determined, the spatial position of the pressure sensor can be accurately determined based on the rotation angle detected by the angle sensor, the spatial position, and the relative positional relationship between the pressure sensor and the laundry processing drum as the laundry processing drum rotates and thereby rotates the pressure sensor between different spatial positions.

[0055] Optionally, in an implementation of this embodiment, as Figure 1AThe figure shows the spatial position of the laundry tub as viewed from a user's perspective. The laundry tub is divided into four spatial locations by a horizontal and vertical plane passing through its axis: Area A, Area B, Area C, and Area D. The 16 sensors are evenly distributed along the circumference of the laundry tub.

[0056] Optionally, in other implementations of this embodiment, such as Figure 2A As shown, it can be divided into three consecutive spatial locations, for example, each area occupies one-third of the circumference. Figure 2B As shown, the area can also be divided into three discrete spatial locations, for example, each area occupies one-sixth of the circumference, and the portion between two adjacent areas does not participate in the clothing pressure detection process. In other words, in this embodiment, the number of spatial locations divided and whether they are continuous can be flexibly designed according to needs (for example, the higher the accuracy requirement, the more continuous spatial locations can be used; the more precise the control, the more spatial locations can be divided). This will be explained below in conjunction with the method embodiment.

[0057] Optionally, in an implementation of this embodiment, as Figure 2A As shown, the number of sensors can be 12; Figure 2B As shown, the number of sensors may be 6. In other words, in this embodiment, the number of sensors may be flexibly designed according to needs (for example, the higher the accuracy requirement, the more sensors may be used).

[0058] Alternatively, in other implementations of this embodiment, the pressure sensors may be unevenly distributed. In this case, since the spatial position is fixed and the relative positional relationship between the pressure sensor and the laundry processing drum is determined, the spatial position of the pressure sensor during the rotation process can also be determined.

[0059] Optionally, in one implementation of this embodiment, referring to Figure 1A Assume that n pressure sensors are evenly spaced along the circumference of the laundry treatment drum. The n pressure sensors are numbered n1, n2, n3...nn. In the initial state, the n pressure sensors are calibrated to Figure 1A Areas A, B, C, and D. When the laundry tub rotates by angle A, the pressure sensor can be recalibrated to the corresponding area based on the position formula A*n / 360 rounded down and the original calibrated position and rotation range of the pressure sensor, i.e., "A*n / 360 rounded down."

[0060] Specifically, Figure 1A and Figure 1BAs shown in the figure, the spatial positions include area A, area B, area C and area D. 16 pressure sensors are evenly spaced along the circumference of the laundry treatment drum and are numbered Q1 to Q16. In the initial state, area A: Q1 to Q4, area B: Q5 to Q8, area C: Q9 to Q12, area D: Q13 to Q16. When the angle sensor rotates 90 degrees clockwise (B→A→D→C), according to Figure 2A 、 2B The position calculation formula is A*n / 360 = 90*16 / 360 = 4. Rounding down the zone layout means the zones need to be moved forward by four sensor positions. After this movement, zone A corresponds to sensors Q5-Q8, zone B corresponds to sensors Q9-Q12, zone C corresponds to sensors Q13-Q15, and zone D corresponds to sensors Q1-Q4. This method calibrates the position of the pressure sensors within the tub. When a corresponding pressure sensor detects the corresponding data, it is said to have detected clothing pressure and the clothing is at its current position. Over a period of time, the pressure sensors detect the corresponding clothing positions based on the order of time, forming a trajectory that can be used to determine the clothing's movement within the tub over time.

[0061] Figure 3 1 is a flow chart of a method for treating clothes in a clothes treating drum according to an embodiment of the present invention. Figure 3 , methods include;

[0062] 300: Obtain the rotation angle of the laundry processing drum and determine the spatial positions of multiple pressure sensors distributed on the laundry processing drum based on the rotation angle. The multiple pressure sensors are distributed along the inner sidewall of the laundry processing drum and are used to detect the pressure exerted on the laundry at different positions during the rotation of the laundry processing drum.

[0063] 302: Obtaining the laundry pressure detected by the plurality of pressure sensors during the rotation of the laundry treatment tub.

[0064] 304: Determine the movement state of the clothing based on the spatial positions of the multiple pressure sensors and the detected clothing pressure. The clothing movement state can be any one or more of the following: clothing trajectory, whether the clothing sticks to the drum, whether the clothing is evenly distributed, whether the clothing is tumbled, and clothing scattering speed (corresponding to the optimal clothing scattering state, where "optimal" refers to the optimal scattering state determined from multiple scattering states, not the absolute optimal state).

[0065] The method provided in this embodiment combines angle sensor data with pressure sensor data to determine the movement state of clothing within the laundry treatment drum during its rotation. Compared to the prior art, which processes clothing based solely on manual settings, this embodiment can understand the clothing movement state and, therefore, perform relevant control of the clothing treatment process based on the clothing movement state to improve the clothing treatment effect. For example, during the washing process, depending on whether the clothing movement state is tumbling, corresponding tumbling control can be performed to improve the clothing washing effect.

[0066] Optionally, in one implementation of this embodiment, in step 300, the rotation angle of the laundry processing drum can be detected by an angle sensor, which is disposed on a rotating shaft that drives the laundry processing drum to rotate. Of course, this also includes obtaining relevant data from a third party (e.g., a server).

[0067] Optionally, in one implementation of this embodiment, in 300, the spatial positions of the multiple pressure sensors distributed on the laundry processing drum are determined based on the rotation angle of the laundry processing drum in the following manner: the spatial positions of the multiple pressure sensors are determined based on the rotation angle of the laundry processing drum, the distribution pattern of the multiple pressure sensors on the laundry processing drum (e.g., uniform distribution, uneven distribution, etc.), and the spatial position division of the multiple laundry processing drums. For related explanations, please refer to the previous description of the laundry processing drum.

[0068] In this implementation, optionally, the clothing processing drum is divided into four spatial positions arranged in sequence along the circumference of the clothing processing drum by a horizontal plane and a vertical plane passing through the axis of the clothing processing drum; multiple pressure sensors are evenly distributed along the circumference of the inner wall of the clothing processing drum, and during the rotation of the clothing processing drum, each of the four spatial positions always has at least one pressure sensor.

[0069] Optionally, in one implementation of this embodiment, in step 304, the clothing movement state is a clothing movement trajectory. In this case, the clothing movement trajectory in the clothing movement state can be determined based on the spatial position of the pressure sensor that detects the clothing pressure and the corresponding time. The pressure sensor that detects the clothing pressure can be a pressure sensor that detects that the clothing pressure is greater than a set threshold. In this implementation, based on the position of the pressure sensor that generates the pressure (the position can be a spatial position or a time interval), the clothing movement trajectory in the clothing movement state can be determined based on the spatial position of the pressure sensor that detects the clothing pressure and the corresponding time interval. Figure 1C The specific position of the pressure sensor in the space position shown in the figure can be determined according to the relative position relationship and rotation angle between the pressure sensor and the laundry processing drum) and the time information corresponding to the position to generate the trajectory information of the laundry. Figure 1AAs shown, an exemplary trajectory information may be "A→B→C→A→B" (without passing through D), or "A→B→C→D→A→B", or "A→B", etc.

[0070] Optionally, in one implementation of this embodiment, the movement state of the clothes can be whether the clothes are close to the drum or not, that is, whether the clothes are close to the drum during the rotation of the clothes processing drum. At this time, in 304, whether the clothes are close to the drum or not in the movement state of the clothes can be determined based on the spatial position of the pressure sensor that detects the pressure of the clothes. In the case where the pressure of the clothes is detected at all spatial positions, or at the spatial position where the pressure of the clothes is theoretically the smallest (for example, referring to Figure 1A If clothing pressure is detected in region D (when the drum rotates in the direction A→B), the clothing movement state is determined to be clothing sticking to the drum; otherwise, the clothing movement state is determined to be clothing not sticking to the drum. It should be noted that in various embodiments of the present invention, "detecting clothing pressure" means that the detected clothing pressure exceeds a set threshold, such as greater than 0, and the specific value is not limited.

[0071] With this implementation, it is possible to accurately determine whether the clothes are running close to the drum during the rotation of the clothes processing drum, thereby providing a status reference for the clothes processing.

[0072] Optionally, in one application of the present embodiment, during the dehydration stage of clothes, the method provided by the present embodiment is used to confirm whether the clothes are sticking to the barrel; if it is determined that the clothes are not sticking to the barrel, the rotation speed of the clothes processing drum is increased until the clothes are sticking to the barrel; if it is determined that the clothes are sticking to the barrel, it is determined whether the clothes are evenly distributed; if the clothes are unevenly distributed, the clothes are shaken out until the clothes are sticking to the barrel and the clothes are evenly distributed; if the clothes are evenly distributed, the rotation speed of the clothes processing drum is increased for high-speed dehydration.

[0073] Optionally, in one implementation of the present invention, the clothing movement state includes whether the clothing is evenly distributed. In this case, in 304, whether the clothing is evenly distributed in the clothing movement state can be determined based on the spatial positions of multiple pressure sensors and the detected clothing pressures. Specifically, when the clothing is against the drum and the difference in clothing pressure detected by pressure detection sensors at different spatial positions is within a set threshold range, the clothing movement state is determined to be evenly distributed; otherwise, the clothing movement state is determined to be unevenly distributed. The interpolation threshold range can be obtained experimentally and is not limited by this implementation.

[0074] By adopting this implementation, it is possible to accurately determine whether the clothes are evenly distributed during the rotation of the clothes processing drum, thereby providing a status reference for clothes processing.

[0075] Optionally, in one implementation of this embodiment, the spatial position includes a rising and falling position and a passing position during the clothing beating process, and the clothing motion state includes whether the clothing is being thrown or not. In this case, in step 304, whether the clothing is being thrown or not in the clothing motion state can be determined based on the clothing pressure detected by the pressure sensors at the rising and falling position and the passing position. If the pressure sensor at the rising and falling position detects clothing pressure but the pressure sensor at the passing position does not detect clothing pressure, it is determined that the clothing is in the beating state; otherwise, it is determined that the clothing is in the non-beating state.

[0076] For example, referring to Figure 1A As shown, area C can be used as a take-off and landing position, and area D can be used as a passing position.

[0077] By adopting this implementation, it is possible to accurately determine whether the clothes are in a clothes-beating state during the rotation of the clothes processing drum, thereby providing a state reference for clothes processing.

[0078] In a specific application of this implementation, during the laundry process, the rotation speed of the laundry treatment drum is adjusted to control the laundry from being thrown. For example, when it is detected that the laundry is in the state of being stuck to the drum, the rotation speed is reduced, and the laundry is being thrown in real time; when the laundry has not reached the lifting position, the rotation speed is increased, and the laundry is being thrown in real time.

[0079] In a specific application of this embodiment, during the laundry washing process, while the laundry is being placed in a tumbling state, the rotational speed of the laundry processing drum is controlled to a relatively high speed within the speed range corresponding to the tumbling state. This can improve the tumbling ability, thereby improving the washing effect. Specifically, since the speed that ensures that the laundry reaches the lifting and lowering position without passing through the passing position is generally within a certain speed range, the highest value within this range or a relatively high value can be used as the rotational speed of the laundry processing drum.

[0080] Optionally, in one implementation of this embodiment, the spatial positions include the rise and fall positions, the passing positions, and the landing positions during the clothing scattering process, and the clothing movement state includes the optimal clothing scattering state. In this case, in step 304, within a set speed range, when clothing pressure is detected at both the rise and fall positions and the landing positions, but no pressure is detected at the passing position, the speed at which the time difference between the detection of clothing pressure at the rise and fall positions and the landing positions is maximized or exceeds a set threshold can be determined to obtain the clothing scattering speed, and the clothing movement state at the clothing scattering speed can be determined as the optimal clothing scattering state (which is better than scattering states corresponding to other speeds).

[0081] For example, referring to Figure 1AAs shown, area C can be used as the lifting position, and area D can be used as the landing position. Since the clothes are cycled through the corresponding positions during the rotation of the clothes treatment drum, there is a time difference when passing through area C and area D during a single cycle. In this implementation, by ensuring that the clothes pass through the lifting position and the landing position, the rotational speed of the clothes treatment drum corresponding to the maximum or relatively larger time difference when passing through these two positions is selected as the clothes scattering rotational speed, and this state is defined as the clothes scattering state (or understood as the optimal clothes scattering state / more scattered clothes state. In essence, compared with the rough clothes scattering in the prior art, this implementation finds a better / optimal rotational speed through the time difference, which can effectively improve the clothes drying and / or care effect).

[0082] In an application of this implementation, during the clothes drying and / or care process, the rotational speed of the clothes treatment drum can be controlled by using the clothes scattering rotational speed.

[0083] Figure 4 It is a schematic diagram of the clothes washing process according to an embodiment of the present invention. Refer to Figure 1A 、 1C 和 Figure 4 In the washing stage, at the beginning, it rotates counterclockwise (A→B) at speed A for T seconds, where 30r / s < A < 60r / s and 0 < T < 15s. Among them, the rotational speed A starts from the lowest rotational speed within the set range. At the same time, it is detected whether the clothes reach Figure 1A the C11 to C14 areas (area C) of, if the clothes do not reach area C, the rotational speed is continuously increased until the clothes reach area C.

[0084] After the clothes reach area C, it is detected whether the clothes reach the D11 to D14 areas (area D). If it reaches area D1, it means that the rotational speed is too high at this time, and the rotational speed needs to be reduced, and then it re-enters the starting stage. If there are clothes that meet the condition of reaching area C1 but not reaching area D1 during the process of increasing the rotational speed from the lowest rotational speed to the highest rotational speed, then clothes beating is achieved at this time, and the current rotational speed is recorded as the first washing rotational speed Aa, and it rotates forward at this washing rotational speed for T1 seconds, stops for T2 seconds, and rotates backward for T1 seconds (3s < T1 < 15s, 3S < T2 < 15s). If the current washing process has not ended, on the basis of meeting the effect of "the clothes reach area C but do not reach area D so as to achieve beating", the rotational speed is increased to Ab (30r / s < Aa < 60r / s and 30r / s < Ab < 60r / s) on the basis of the first washing rotational speed Aa and re-enters the starting stage. In this way, by increasing the rotational speed within the rotational speed range that can achieve beating, the momentum of the clothes washing and beating is increased, and the washing effect is improved.

[0085] It should be noted that as Figure 1A 和 1CAs shown, although the detection mentioned in this embodiment or other embodiments is whether it is located within the large regions A, B, C, and D. In fact, as mentioned above, in different embodiments, the spatial region can be flexibly divided. For example, A11 and A12 can be taken as region A, and C14, C13, and C12 can be taken as region C, etc. The present invention does not enumerate this, but the method of position conversion based on the dual relationship of the relative position relationship between the pressure sensor and the laundry treatment drum and the spatial position division of the laundry treatment drum, as well as the way of flexibly dividing the spatial position as needed, all fall within the protection scope of the present invention.

[0086] Figure 5 is a schematic flowchart of a laundry dehydration method according to an embodiment of the present invention. Referring to Figure 5 as shown, the method includes:

[0087] After the process starts, the dehydration process begins at a lower rotational speed, and it is detected whether the laundry dewatering against the drum at this lower dehydration rotational speed. Specifically, the washing machine rotates counterclockwise at a rotational speed of A for T seconds (30 r / s < A < 60 r / s, 0 < T < 15 s). It is judged whether the laundry reaches the regions C11 to C14 (region C) and the regions D11 to D14 (region D). If it does not dewater against the drum, the rotational speed is increased so that the laundry can move from region C to region D during counterclockwise dehydration.

[0088] After the laundry adheres to the drum wall at the lower rotational speed, it is detected whether the laundry is evenly distributed. If it is not evenly distributed, it is de-tangled and loosened. Specifically, the rotational speed can be reduced to 0, and then rotated counterclockwise at a rotational speed of A for T seconds (30 r / s < A < 60 r / s, 0 < T < 15 s).

[0089] If it is evenly distributed, the high rotational speed condition is met, so the dehydration rotational speed is gradually increased to the maximum dehydration rotational speed until the dehydration process is completed.

[0090] By adopting the method provided in this embodiment, it is possible to achieve dehydration at a high rotational speed while ensuring that the laundry adheres evenly to the wall during the dehydration stage, improving the dehydration effect.

[0091] Figure 6 is a schematic flowchart of a drying / care method according to an embodiment of the present invention. Referring to Figure 6 , the method includes:

[0092] After the drying / care stage starts, first, the washing machine rotates counterclockwise at a rotational speed of A for T seconds, and the initial value of A is 10 r / s (10 r / s < A < 75 r / s, 0 < T < 60 s).

[0093] Then, a speed search is performed within the range of 10r / s to 75r / s to obtain the minimum speed Bmin for the clothes to reach area C and the minimum speed Bmax for the clothes to reach area D in the process of multiple cycles and gradually adjusting the speed in each cycle. In other words, the speed range in which the clothes reach area C but not area D can be obtained. Specifically, it is possible to detect whether the clothes have reached area C in the initial stage. If so, the speed at this time is recorded as Bmin; if not, the speed is increased within the set range of 10r / s to 75r / s (for example, the speed is increased step by step according to the number of cycles, that is, a value is increased for each cycle), and re-judgment is made. In the case of reaching area C for the first time, Bmin can be obtained. In the case of reaching area C, the speed is continued to increase until it is detected that area D has been reached for the first time, and the speed at this time is recorded as Bmax. Thus, the speed range [Bmin, Bmax] in which the clothes reach area C but not area D can be obtained. It should be noted that, with regard to Figure 6 In the judgment box "Is the speed Bmax greater than 0 when the speed reaches the D11 to D14 area for the first time?", the default condition is: if Bmax is not detected, then Bmax=0, and when Bmax is detected, it is assigned its actual value.

[0094] Perform a speed search within the speed range [Bmin, Bmax) obtained above to determine the speed Amax corresponding to the longest time it takes for the clothes to reach area A from area C, and use this speed as the corresponding optimal drying / care speed, and dry / care at this speed until the end of the process.

[0095] Specifically, each time the clothing is detected to have reached area A from area C but not area D, the time Tx (i.e., Txn) and the corresponding rotational speed Ax (i.e., Axn) for the current (i.e., nth) time the clothing reaches area A from area C from area C are recorded. (Tx represents the time the clothing reaches area A from area C, Ax represents the rotational speed corresponding to Tx, Txn represents the time the clothing reaches area A from area C for the nth time, Axn represents the rotational speed corresponding to Txn, and n is a positive integer representing the number of times the clothing has been detected to have reached area A from area C but not area D.) Initially, Tmax is set to Tx1, and the rotational speed corresponding to Tmax is set to Amax=Ax1, where Tx1 is the time the clothing is first detected to have reached area A from area C, and Ax1 is the rotational speed corresponding to Tx1.

[0096] Each subsequent time the speed is increased and the device detects that the garment has moved from area C to area A but not to area D, it determines whether the corresponding Tx (i.e., Txn) is greater than Tmax. If so, then: Tmax = Txn, and Amax = Axn. Tmax is the maximum recorded time for the garment to move from area C to area A, and Amax is the speed corresponding to Tmax.

[0097] If the current corresponding Tx (ie, Txn) is not greater than Tmax, then determine whether the current speed Ax (ie, Axn) is equal to Bmax. If so, determine the optimal drying / nursing speed to be Amax, Amax∈[Bmin,Bmax), and then dry / nursing at Amax drying / nursing speed until the drying / nursing stage ends. If not, increase the drying speed within the range of [Bmin,Bmax), and then refer to Figure 6 The logic shown is looped for judgment.
