[0066] In this embodiment, an underwear washing structure is provided in the washing tub 1 to realize dedicated washing of underwear and reduce the deformation of underwear during washing; at the same time, by monitoring and recording the motor power during underwear washing, and determining whether the shoulder straps / back straps are entangled with the washing structure, if so, an untangling process is executed, thereby solving the problem of entanglement caused by excessively long shoulder straps and back straps during underwear washing.

[0067] Combine Figure 1 The laundry processing device and the underwear washing structure therein are further described in this embodiment. The laundry processing device includes an underwear washing structure disposed within a washing tub. The underwear washing structure is preferably detachably disposed within the washing tub and is used to support underwear and prevent deformation. During the washing process, motor operating parameters, such as motor power, are periodically monitored and recorded during the rotation of the washing tub. These parameters are compared with power values ​​calculated by a program to determine whether the underwear shoulder straps and back straps are entangled with the underwear washing structure. If entanglement occurs, an untangling process is performed.

[0068] The underwear washing structure is a standalone accessory, detachably mounted on a main underwear frame 7, which is rigidly connected to the washing tub. It features a contoured frame 4 that supports the desired washing object and prevents deformation. It also includes a kneading structure 5, mounted on the outer surface of the contoured frame 4, which rubs and washes the desired washing object. To wash, the desired washing object is placed over the contour of the kneading structure 5, and the underwear washing structure is then installed inside the washing tub.

[0069] Further optionally, the preset washing object is a bra;

[0070] The underwear washing structure is an underwear plug-in plate assembly, which includes a plug-in plate main frame 6, which serves as the main supporting component for placing underwear and divides the clothing processing barrel into two areas, left and right or upper and lower areas; a contoured frame 4, whose outer contour forms a raised feature consistent with the arc surface of the inner side of the underwear cup; a kneading structure 5, which is assembled on the outer contour of the contoured frame 4, is generally made of flexible material and fits the inner side of the underwear cup for kneading and washing to improve the cleaning of the inner side of the cup; a heart-shaped beam 8, which is arranged on the upper part of the underwear main frame 7 and is used to fit the heart position of the underwear, so as to place the left and right cups of the underwear at the highest part of the left and right or upper and lower areas of the clothing processing barrel.

[0071] The contoured frame 4 is detachably mounted on the inserting plate 51. The corresponding contoured frame 4 can be mounted on the inserting plate 51 according to actual needs to accommodate preset washing objects of different types or sizes. The contoured frame 4 supports the preset washing objects, expands the scope of use of the contoured frame 4, and improves the compatibility of the contoured frame 4 with the preset washing objects.

[0072] The kneading and washing structure 5 also includes a kneading and washing outer layer, which is sleeved on the outer side of the contoured frame 4. The corresponding kneading and washing outer layer can be sleeved on the contoured frame 4 according to actual needs to adapt to preset washing objects of different types or sizes; the preset washing objects are sleeved on the outer side of the kneading and washing outer layer, and the kneading and washing outer layer has a washing effect on the preset washing objects, thereby expanding the use range of the kneading and washing outer layer and improving the compatibility of the kneading and washing outer layer with the contoured frame 4.

[0073] Further optionally, the motor operating parameters include motor power and / or motor current.

[0074] Further optionally, monitoring and recording the motor operating parameters when the washing tub rotates, and determining whether the preset washing object is entangled between the kneading structure and the mounting assembly according to the motor operating parameters includes the following steps:

[0075] A1, monitor and record the motor power W of the washing tub during washing i ;

[0076] A2, calculate the motor power W within the monitoring time t i The average value of

[0077] A3, the motor power W i The average value W' i and the preset motor power threshold W max Make comparisons;

[0078] A4, if W' i ≥W max , it is determined that the preset washing object is entangled between the kneading structure and the installation component.

[0079] Further optionally, monitoring and recording the motor operating parameters when the washing tub rotates, and determining whether the preset washing object is entangled between the kneading structure and the mounting assembly according to the motor operating parameters includes the following steps:

[0080] B1, periodically monitor and record the motor power W during the washing process of the washing tub i , i represents the number of cycles;

[0081] B2, based on the power change value ΔW between each two adjacent cycles i Determining whether a preset washing object is entangled between the kneading structure and the installation component;

[0082] B3, in power change value ΔW i When it is greater than the set value, i≥2, it is considered that the preset washing object is entangled between the kneading structure and the installation component.

[0083] Further optionally, the method further includes: determining the motor power threshold W using the motor power W0 and the winding coefficient A monitored in the first cycle. ma .

[0084] This control method monitors and records the motor power when washing underwear, compares the average motor power within the set monitoring time t with the preset motor power threshold, or compares the power change value of each two adjacent monitoring cycles with the set value to determine whether the washed clothes are entangled between the kneading structure and the installation component. It can more accurately judge the entanglement status of the underwear. If entangled, the untangling process is executed, solving the problem of entanglement caused by excessively long shoulder straps and back straps when washing underwear.

[0085] Specifically, the detection frequency is to perform motor power detection every X minutes during the washing process, and one detection cycle is Y seconds when the washing tub rotates; for example, X is 5 and Y is 5;

[0086] Alternatively, the motor power limit value W is calculated using the following formula: max :

[0087] W max =AW0.

[0088] Specifically, the average motor power W0 is recorded at the beginning of the washing phase. At this time, it is considered that the underwear shoulder straps, back straps, etc. are not entangled with the underwear washing structure. Considering the monitoring accuracy, this embodiment proposes a winding coefficient, and the product of the winding coefficient A and W0 is used as the motor power limit value W max .

[0089] Further optionally, executing the unwinding procedure includes:

[0090] The washing tub is controlled to perform n times of forward and reverse reciprocating motion with different unwinding rotation-stop ratios, different unwinding rotation speeds, and different unwinding accelerations, so as to generate relative displacement between the preset washing object and the underwear washing structure.

[0091] Specifically, the untangling process is to perform multiple reciprocating forward and reverse operations of the underwear barrel, with a forward and reverse start-stop ratio, rotation speed, and acceleration that are different from those in the normal washing process. The unwinding turn-stop ratio, unwinding rotation speed, and unwinding acceleration of the n forward and reverse operations are all different, which causes relative displacement of the underwear shoulder straps, back straps, and underwear washing structure, thereby achieving the untangling effect.

[0092] Further optionally, the jth unwinding rotation-stop ratio in the n-times forward and reverse reciprocating motion is T jSeconds, stop t j Seconds, turn counterclockwise T j Seconds, stop t j seconds, where T j+1 =T j +f,t j+1 =t j +f, where f is a constant; in this way, the controller can calculate the parameters based on the data of the previous cycle and directly assign the parameters for the machine to run in this cycle to achieve the unwinding effect;

[0093] The jth unwinding speed in the n-time forward and reverse reciprocating motion is V j , V j =f1(b);

[0094] The jth unwinding speed in the n-time forward and reverse reciprocating motion is a j , a j =f2(b);

[0095] b=W j / W0,W j is the current real-time motor power;

[0096] Further optionally, V j =B+Cb;a j =D+Eb;

[0097] Among them, B, C, D, and E are all constants, V j >0, C<0, E>0, a j >0.

[0098] The speed is changed here to take into account the problem of rotational centrifugal force. The measured motor power reaches the threshold range of the untangling process. The centripetal force is reduced by reducing the speed, and untangling is attempted. Therefore, C<0 and B+Cb>0; the acceleration is changed to take into account the problem of inertia. By increasing the acceleration to increase the inertia, the shoulder strap is more likely to produce relative displacement with the washing structure, making it easier to untangle.

[0099] Moreover, the clockwise and counterclockwise rotation speeds and accelerations during a single reciprocating rotation are the same.

[0100] Further optionally, executing the decompression procedure further includes:

[0101] When controlling the washing tub to perform the jth forward and reverse reciprocating motion of n times, W j and W max Make a comparison;

[0102] In W j ≥W max When the washing tub is in the state of being moved, the washing tub is controlled to perform the next reciprocating motion;

[0103] In W j <W max When the unwinding is completed, it is considered to be successful, the unwinding program is exited, and the washing program continues to run until the washing is completed.

[0104] Further optionally, when Wj≥W max When executing the unwinding procedure, the following steps are also performed:

[0105] When j≥n, the unwinding process is considered to be completed once;

[0106] Record the number of times the unwinding program is run k;

[0107] When k≥m, m is the set number of unwinding times, and the washing program continues to run until the end of washing;

[0108] When k<m, the washing tub is controlled to perform the reciprocating motion of the next cycle.

[0109] Preferably, m=1 (times), f=1 (seconds), that is, T j+1 =T j +1,t j+1 =t j +1;

[0110] Combine Figure 3 , further details the execution unwinding process:

[0111] (1) Calculate the current real-time motor power growth coefficient b, b = W j / W0;

[0112] (2) Calculate the washing tub speed V during the untangling process j =B+Cb, acceleration a j =D+Eb;

[0113] (3) The washing tub is set and calculated according to the rotation and stop ratio. j Stop j Reverse T j Stop j , speed V j , acceleration a j Run a cycle;

[0114] (4) j = j++ (initial 1);

[0115] (5) Determine whether the number of reciprocating cycles j of the washing tub is greater than the maximum number of cycles n set by the program;

[0116] If yes, go to step (6), otherwise, return to step (1);

[0117] (6) Determine whether the number of times the untangling process is executed in this washing process is greater than or equal to 1;

[0118] If yes, go to step (7), otherwise, return to step (1);

[0119] (7) Continue running until the washing is completed.
