[0002] In the damping system of the clothes treatment device, a spring (stiffness component) connects an outer drum and a cabinet to suspend the drum component on the cabinet, the bottom of the outer drum is connected to the cabinet through a damper (damping component), and a counterweight (mass component) is fixed on the drum component. The spring is used for buffering the vibration of the drum component, reducing the vibration load transmission of the drum component to the cabinet, the damper is used for consuming the vibration energy of the drum component, reducing the vibration of the drum component, and the counterweight is used for increasing the weight of the drum component and absorbing the vibration energy of the drum component. In addition, a door seal is also provided to seal the water in the drum, but because the door seal is connected between the outer drum and the cabinet, it also affects the vibration of the drum component, and the door seal can be regarded as a stiffness component with properties similar to the spring.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the protection scope of the present application.

In addition, the terms “first” and “second” are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as “first” and “second” can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of “plurality” is two or more, unless otherwise explicitly and specifically limited.

[0048] In the present application, the word “exemplary” is used to mean “serving as an example, instance, or illustration.” Any implementation described as “exemplary” in the present application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the present application. In the following description, for the purposes of explanation, numerous details are set forth. It should be appreciated that a person having ordinary skill in the art can realize further implementations of the present application without using these specific details. In other instances, well-known structures and processes are not elaborated in order not to obscure the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited by the implementations shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0049] The present application provides a laundry treating apparatus and a control method, a control device and a storage medium thereof, which are described in detail as follows.

[0050] Through the research of the present inventor, it is found that the curve diagram between the rotational speed and the amplitude under different stiffness conditions is as follows, Figure 1As shown in FIG. 1 and FIG. 2, the vibration amplitude corresponding to the large stiffness is smaller than the vibration amplitude corresponding to the small stiffness when the rotating speed is at a low level, and the vibration amplitude corresponding to the small stiffness is larger than the vibration amplitude corresponding to the large stiffness when the rotating speed is at a high level. Therefore, the stiffness of the damping system of the clothes treatment apparatus is suitably large when the clothes treatment apparatus is operated at a low rotating speed, and the stiffness of the damping system of the clothes treatment apparatus is suitably small when the clothes treatment apparatus is operated at a high rotating speed. However, the stiffness of the damping system of the clothes treatment apparatus cannot be adjusted in the prior art, and the clothes treatment apparatus is operated at the same stiffness at a high rotating speed and at a low rotating speed, which is not good for suppressing vibration. The stiffness of the clothes treatment apparatus in the prior art is determined according to the suppression of vibration at a high rotating speed. With the pursuit of a quiet and safe home environment, the clothes treatment apparatus needs to have small vibration at a low rotating speed and at a high rotating speed.

[0051] Therefore, in combination with Figure 2 and Figure 3 shown in the drawings, the embodiment of the present application provides a clothes treatment apparatus 10, which comprises:

[0052] a cabinet 100;

[0053] a drum assembly 200 arranged in the cabinet 100;

[0054] a damping system 300 connected to the drum assembly 200 and the cabinet 100; and

[0055] a magnetic assembly 400, which comprises a first magnetic member 410 and a second magnetic member 420; one of the first magnetic member 410 and the second magnetic member 420 is arranged on the cabinet 100, and the other is arranged on the drum assembly 200, and the first magnetic member 410 and the second magnetic member 420 are arranged opposite to each other and can repel each other; at least one of the first magnetic member 410 and the second magnetic member 420 is an electromagnet; the electromagnet has a power-on state and a power-off state; when the electromagnet is in the power-on state, the first magnetic member 410 and the second magnetic member 420 repel each other, so as to increase the stiffness of the damping system 300; when the electromagnet is in the power-off state, the repulsion between the first magnetic member 410 and the second magnetic member 420 disappears.

[0056] In the technical scheme of the embodiment of the present application, the magnetic assembly is arranged, the magnetic assembly comprises a first magnetic part 410 and a second magnetic part 420; one of the first magnetic part 410 and the second magnetic part 420 is arranged on the cabinet 100, and the other is arranged on the drum assembly 200, and the two are arranged oppositely and can repel each other; at least one of the first magnetic part 410 and the second magnetic part 420 is an electromagnet; the electromagnet has a power-on state and a power-off state; when the electromagnet is in the power-on state, the first magnetic part 410 and the second magnetic part 420 repel each other, so as to increase the rigidity of the damping system 300; when the electromagnet is in the power-off state, the repulsion of the first magnetic part 410 and the second magnetic part 420 disappears. Therefore, the laundry treating apparatus 10 can adjust the power-on state and the power-off state of the electromagnet according to the needs in different stages, so as to adjust the rigidity of the damping system and meet the damping needs.

[0057] Specifically, in the embodiment, the first magnetic part 410 and the second magnetic part 420 are magnetically repulsive after the electromagnet is powered on, and the magnetic repulsion disappears after the electromagnet is powered off. When the electromagnet is magnetically repulsive, the drum assembly 200 is repelled when moving towards the cabinet 100 due to vibration, which is equivalent to increasing the rigidity of the system; after being powered off, the additional system rigidity is equivalent to being removed, so as to realize the rigidity control, and the power-on and power-off of the electromagnet are controlled according to the rigidity size needs of the system.

[0058] As shown in Figure 1 , curve (2) is a curve graph of the inner drum speed and amplitude after the electromagnet is powered on; curve (1) is a curve graph of the inner drum speed and amplitude after the electromagnet is powered off. As can be seen from the figure, when the speed is small, the amplitude in curve (2) is smaller than the amplitude in curve (1). When the speed is large, the amplitude of curve (1) is smaller than the amplitude in curve (2). Therefore, in the specific implementation process, in the low speed stage, the electromagnet is controlled to be in the power-on state, and the speed of the drum assembly is controlled to be lower than the preset speed; in the high speed stage, the electromagnet is controlled to be in the power-off state, and the speed of the drum assembly is controlled to be higher than the preset speed. The preset speed is the resonance speed of the laundry treating apparatus after the electromagnet is powered off.

[0059] In some specific embodiments, the first magnetic part 410 and the second magnetic part 420 can both be electromagnets. Both of them are powered on and powered off at the same time. When powered on, the opposite sides of the first magnetic part 410 and the second magnetic part 420 are the same side (such as both S poles or N poles), so as to repel each other.

[0060] In some embodiments, the first magnetic member 410 is arranged on the cabinet 100, and the second magnetic member 420 is arranged on the drum assembly 200. The first magnetic member 410 is an electromagnet. The second magnetic member 420 is a permanent magnet. When the first magnetic member 410 is energized, the side of the first magnetic member 410 facing the second magnetic member 420 and the side of the second magnetic member 420 facing the first magnetic member 410 are of the same polarity (e.g., both S-pole or both N-pole), and thus repel each other.

[0061] In some embodiments, the first magnetic member 410 is arranged on the cabinet 100, and the second magnetic member 420 is arranged on the drum assembly 200. The first magnetic member 410 is a permanent magnet. The second magnetic member 420 is an electromagnet. When the second magnetic member 420 is energized, the side of the second magnetic member 420 facing the first magnetic member 410 and the side of the first magnetic member 410 facing the second magnetic member 420 are of the same polarity (e.g., both S-pole or both N-pole), and thus repel each other.

[0062] In embodiments, the first magnetic member 410 and the second magnetic member 420 of the magnetic assembly are arranged on the drum assembly 200 and the cabinet 100, respectively, without the need to adjust the internal structure and the mounting structure of the vibration damping system, and thus is a low-cost, high-efficiency and high-benefit improvement.

[0063] In embodiments, the vibration damping system includes a damping shock absorber 310 and a damping spring 320. The damping spring 320 connects the upper portion of the drum assembly 200 and the top portion of the cabinet 100 to suspend and damp the drum assembly 200. The damping shock absorber connects the lower portion of the drum assembly 200 and the bottom portion of the cabinet 100 to support and damp the drum assembly 200.

[0064] In embodiments, the drum assembly 200 includes an outer drum 220 and an inner drum 210 arranged in the outer drum 220. The inner drum 210 is rotatable, while the outer drum 220 is not rotatable. The damping shock absorber 310 and the damping spring 320 are both connected to the outer drum 220. One of the first magnetic member 410 and the second magnetic member 420 is arranged on the outer drum 220, and the other is arranged on the cabinet 100.

[0065] In embodiments, the electromagnet is connected to a power supply device through a circuit structure. The circuit structure includes a wire and a switch. The energized state and the de-energized state of the electromagnet are adjusted by the switch. The power supply device can be an electric energy conversion device of the laundry treatment apparatus 10; the electric energy conversion device is connected to an external power grid.

[0066] As an optional implementation of the above embodiment, the magnetic assembly 400 includes multiple pairs; multiple pairs of the magnetic assembly are sequentially and evenly spaced along the circumference of the barrel assembly 200. In an embodiment, multiple pairs of the magnetic assembly are sequentially and evenly spaced along the circumference of the barrel assembly 200, so that when the first magnetic member 410 and the second magnetic member 420 are in a repelling state, the vibration of the barrel assembly 200 can be inhibited in multiple directions.

[0067] For example, in some embodiments, three pairs of the magnetic assembly are sequentially and evenly spaced along the circumference of the barrel assembly 200. For another example, in some embodiments, five pairs of the magnetic assembly are sequentially and evenly spaced along the circumference of the barrel assembly 200.

[0068] As an optional implementation of the above embodiment, the magnetic assembly includes four pairs; four pairs of the magnetic assembly are sequentially and evenly spaced along the circumference of the barrel assembly 200; wherein two pairs of the magnetic assembly in the four pairs are arranged along a first radial direction of the barrel assembly 200, and the other two pairs of the magnetic assembly are arranged along a second radial direction of the barrel assembly 200; wherein the first radial direction and the second radial direction are perpendicular to each other. In this way, when the first magnetic member 410 and the second magnetic member 420 are in a repelling state, the vibration of the barrel assembly 200 is inhibited in the first radial direction and the second radial direction, and since the first radial direction and the second radial direction are perpendicular to each other, the resultant force of the repulsive force can inhibit the vibration of the barrel assembly 200 along the remaining radial directions.

[0069] As an optional implementation of the above embodiment, the first radial direction is parallel to the horizontal direction, and the second radial direction is perpendicular to the horizontal direction. As shown in Figure 2 The four magnetic assemblies include a first magnetic assembly 401, a second magnetic assembly 402, a third magnetic assembly 403, and a fourth magnetic assembly 404. The first magnetic assembly 401 and the third magnetic assembly 403 are arranged vertically, and the second magnetic assembly 402 and the fourth magnetic assembly 404 are arranged horizontally.

[0070] As an optional implementation of the above embodiment, the repulsion forces generated by the two pairs of magnetic assemblies along the first radial direction of the drum assembly 200 are the same; the repulsion forces generated by the two pairs of magnetic assemblies along the second radial direction of the drum assembly 200 are the same. In the embodiment, the repulsion forces generated by the two pairs of magnetic assemblies along the first radial direction of the drum assembly 200 are the same; the repulsion forces generated by the two pairs of magnetic assemblies along the second radial direction of the drum assembly 200 are the same. So that the drum assembly 200 is balanced in the first radial direction and balanced in the second radial direction, avoiding the eccentricity of the drum assembly 200. In the embodiment, the first magnetic members 410 of the magnetic assemblies are the same specification products, and the second magnetic members 420 of the magnetic assemblies are the same specification products. The electromagnets pass through the same current when powered on. The gaps between the first magnetic members 410 and the second magnetic members 420 of the two pairs of magnetic assemblies along the first radial direction are the same. The gaps between the first magnetic members 410 and the second magnetic members 420 of the two pairs of magnetic assemblies along the second radial direction are the same. Secondly, the present application also provides a control method of a clothes processing apparatus, which is used to control the clothes processing apparatus as described in the above embodiment. The control method of the present application is executed by the controller of the clothes processing apparatus to realize the steps of the control method proposed in the present application.

[0071] As shown in Figure 4 , the control method comprises:

[0072] S100, in a first preset phase, controlling the electromagnet to be in an energized state, and controlling the rotation speed of the drum assembly to be lower than a preset rotation speed;

[0073] S300, in a second preset phase, controlling the electromagnet to be in a de-energized state, and controlling the rotation speed of the drum assembly to be higher than the preset rotation speed.

[0074] In the embodiment, in the first preset phase, when the rotation speed of the inner drum of the drum assembly is lower than the preset rotation speed, the electromagnet is in the energized state, and the repulsion force is generated to improve the stiffness of the damping system and suppress the vibration of the drum assembly at low rotation speed of the inner drum. In the second preset phase, when the rotation speed of the inner drum of the drum assembly is lower than the preset rotation speed, the electromagnet is in the de-energized state, and the repulsion force is removed, and the stiffness of the damping system is reduced to suppress the vibration of the drum assembly at high rotation speed of the inner drum. Therefore, the clothes processing apparatus operates in a low-vibration condition in the first preset phase and the second preset phase.

[0075] In the embodiment, the first preset phase can include a washing phase, a weighing phase, an eccentricity detection phase, and the like. The second preset phase can include a dehydration phase and the like.

[0076] As an optional implementation of the above embodiment, the preset rotating speed is a resonance rotating speed when the electromagnet is powered off. In an embodiment, the resonance rotating speed is a resonance rotating speed of the magnetic assembly when the electromagnet is powered off to distinguish the low rotating speed and the high rotating speed. As shown in FIG. 8, because the system stiffness is large after the electromagnet is powered on, the resonance rotating speed of the magnetic assembly after the electromagnet is powered on is larger than the resonance rotating speed when the electromagnet is powered off. Therefore, when the inner drum is running at a low rotating speed, the rotating speed is smaller than the resonance rotating speed when the electromagnet is powered off, and thus is smaller than the resonance rotating speed after the electromagnet is powered on. That is, when the inner drum is running at a low rotating speed, the rotating speed is much smaller than the resonance rotating speed after the electromagnet is powered on, and thus does not cause resonance of the laundry device. Figure 1

[0077] As shown in FIG. 9, as an optional implementation of the above embodiment, in the first preset stage, the electromagnet is controlled to be in a powered-on state, and the rotating speed of the drum assembly is controlled to be lower than the preset rotating speed, including: Figure 5

[0078] S101, controlling the inner drum of the drum assembly to run at a first rotating speed; the first rotating speed is smaller than the preset rotating speed;

[0079] S102, controlling the electromagnet to be in a powered-on state;

[0080] S103, obtaining a first eccentricity value of the inner drum;

[0081] S104, if the first eccentricity value is smaller than a first preset eccentricity value, controlling the inner drum of the drum assembly to run at a second rotating speed; the second rotating speed is larger than the first rotating speed and smaller than the preset rotating speed; wherein the first preset eccentricity value is a safety threshold value when the inner drum of the drum assembly runs at the second rotating speed.

[0082] In an embodiment, by detecting the first eccentricity value of the inner drum when the inner drum runs at the first rotating speed, it is determined whether the inner drum can run at the second rotating speed.

[0083] In the stage before formal dehydration, the inner drum runs at the first rotating speed, and by detecting the first eccentricity value of the inner drum when the inner drum runs at the first rotating speed, it is determined whether the inner drum can run at the second rotating speed. If the inner drum cannot run at the second rotating speed, it indicates that the load is eccentric, and at this time, the load needs to be distributed. After distribution, it is determined again until the load is uniformly distributed. In this process, the electromagnet is in a powered-on state, so that the damping system has large stiffness, which is helpful to suppress vibration.

[0084] As an optional implementation of the above embodiment, the first rotating speed is an eccentricity detection rotating speed, and the second rotating speed includes a weighing rotating speed and a pre-dewatering rotating speed. In an embodiment, the eccentricity detection rotating speed is smaller than the weighing rotating speed and the pre-dewatering rotating speed. In some embodiments, the weighing rotating speed is smaller than the pre-dewatering rotating speed. ​​

[0085] As Figure 6 shown, as an optional implementation of the above embodiment, the control method further comprises:

[0086] S201, in the third preset phase, controlling the electromagnet to be in a power-off state, and controlling the rotating speed of the inner drum of the drum assembly to be lower than a preset rotating speed;

[0087] S202, obtaining a second eccentricity value of the inner drum;

[0088] S203, if the second eccentricity value is less than a second preset eccentricity value, controlling the clothes processing device to enter the second preset phase; wherein the second preset eccentricity value is a safety threshold value of the clothes processing device when running in the second preset phase;

[0089] Wherein, the third preset phase is between the first preset phase and the second preset phase.

[0090] In the embodiment, the third preset phase is a transition phase between the first preset phase and the second preset phase. When the clothes processing device is dehydrating, eccentricity detection needs to be performed to determine whether the inner drum can be dehydrated at high speed. Moreover, when dehydrating at high speed, the electromagnet is in a power-off state, reducing the stiffness. Therefore, when performing eccentricity detection, the electromagnet also needs to be in a power-off state. Therefore, in the third preset phase, the electromagnet needs to be controlled to be in a power-off state, and the rotating speed of the inner drum of the drum assembly needs to be controlled to be lower than a preset rotating speed; at this time, the rotating speed of the inner drum is the eccentricity detection rotating speed. After the electromagnet is powered off, the second eccentricity value of the inner drum is obtained, and if the second eccentricity value is less than the second preset eccentricity value, the clothes processing device is allowed to enter the second preset phase at this time. When the second eccentricity value is less than the dehydration eccentricity safety threshold value in the dehydration phase, the inner drum is allowed to dehydrate at high speed, and at this time the electromagnet is in a power-off state, the damping system has small stiffness, and can better suppress vibration.

[0091] As Figure 7 shown, the steps of a control method of a clothes processing device applied to a dehydration link are exemplified. The dehydration link includes a first processing phase S1, a third processing phase S2 and a second processing phase S3 performed in time sequence. Among them, the third processing phase S2 is a transition phase.

[0092] In the first processing stage S1, the electromagnet is always in the powered state. After the load is scattered, the inner cylinder runs at the first rotating speed, and it is determined whether the first eccentricity value is less than the weighing eccentricity value. If yes, the weighing stage is entered, the inner cylinder is raised to the weighing rotating speed, the first weight of the wet load is obtained, and if no, the load is scattered. After the weighing is completed, the inner cylinder is lowered to the first rotating speed, and it is determined whether the first eccentricity value is less than the pre-removal eccentricity value. If yes, the pre-removal stage is entered, the inner cylinder is raised to the pre-removal rotating speed, and if no, the load is scattered. After the pre-removal, the inner cylinder is lowered to the first rotating speed, and it is determined whether the first eccentricity value is less than the weighing eccentricity value. If yes, the weighing stage is entered, the inner cylinder is raised to the weighing rotating speed, the second weight of the wet load is obtained, and if no, the load is scattered. Whether the pre-removal is needed is determined by the second weight and the first weight. If yes, the pre-removal is re-performed. If no, the inner cylinder is lowered to the first rotating speed, and then the second processing stage S2 is entered. (The electromagnet is powered off after being lowered to the first rotating speed, so as to avoid large vibration of the clothes processing device caused by powering off of the electromagnet at a high rotating speed.)

[0093] In the second processing stage S2, the electromagnet is powered off, and the inner cylinder is lowered to the first rotating speed. Then it is determined whether the second eccentricity value is less than the dehydration eccentricity value. If yes, the third processing stage S3 is entered. If no, the load is scattered.

[0094] In the third processing stage S3, the electromagnet is powered off, the rotating speed of the inner cylinder is rapidly increased, rapidly passes through the resonance rotating speed, reaches the dehydration rotating speed, and then the dehydration is completed.
