[0045] The specific structure of the balancer 10 will be mainly described below.

[0046] Reference Figures 1 to 5 In an embodiment of the present invention, the balancer 10 includes:

[0047] A balancing ring 100, wherein the balancing ring 100 has a receiving cavity extending along the extending direction of the balancing ring 100, and the balancing ring 100 is provided with a through hole 101, wherein the through hole 101 is connected to the receiving cavity, and wherein the through hole 101 is configured to be connected to one end of a transmission tube 30, wherein the other end of the transmission tube 30 is connected to a storage box 50, and a driving device is provided on the transmission tube 30, so that the damping medium in the storage box 50 is driven by the driving device to enter the receiving cavity, or the damping medium in the receiving cavity is driven by the driving device to be led out to the storage box 50;

[0048] A damping medium enters or flows out of the accommodating chamber under the action of a driving device.

[0049] Specifically, in this embodiment, the accommodating cavity may extend along the extension direction of the balance ring 100 , and the cross-section of the accommodating cavity may be circular, square, rectangular, or even other special shapes. In this embodiment, a circular shape is taken as an example.

[0050] The damping medium can be a damping solid or a damping liquid, such as silicone oil, water, etc. In this embodiment, water is taken as an example. The balance ring 100 is provided with a through hole 101, so that the damping medium can enter the accommodating chamber through the through hole 101, and can also flow out of the accommodating chamber through the through hole 101, so that the amount of the damping medium in the accommodating chamber can be adjusted. In actual use, one end of the transmission tube 30 can be inserted into the through hole 101, and the other end can be connected to the storage box 50, and then the damping medium in the storage box 50 is pumped into the accommodating chamber through a driving device such as a water pump, or the damping medium in the accommodating chamber is pumped into the storage box 50 to adjust the amount of the damping medium in the accommodating chamber.

[0051] The technical solution of the present invention is to open a through hole 101 on the balancing ring 100 so that the damping medium can enter the accommodating cavity through the through hole 101, and can also flow out of the accommodating cavity through the through hole 101. In this way, the amount of damping medium in the accommodating cavity can be adjusted, so that the amount of damping medium in the accommodating cavity can be controlled accordingly according to the weight of the clothes in the drum 20 and the rotation speed of the drum 20 to ensure the balancing effect of the balancer 10. Accordingly, the balancer 10 can be suitable for drums 20 with different loads and / or different rotation speeds, thereby improving the applicability of the balancer 10.

[0052] Regarding the proportion of the damping medium, in some embodiments, the damping medium is a damping liquid, and the ratio of the volume of the accommodating chamber to the volume of the damping liquid is 1.5:1-4:1, such as 2:1, 3:1, etc. The proportion of the volume of the damping liquid should not be too small, otherwise the damping medium is prone to violent flow, which is not conducive to ensuring the stability of the damping medium, and thus not conducive to ensuring the stability of the balancer 10; it should not be too high, otherwise the cavity part in the accommodating chamber is too small, making the movement smoothness of the damping medium lower. In actual application, the volume of the damping liquid will be adjusted according to the weight of the clothes in the drum 20 and the rotation speed of the drum 20. The volume of the accommodating chamber can be controlled by controlling the size of the balance ring 100, so that the ratio of the volume of the accommodating chamber to the volume of the damping liquid is maintained within a preset range.

[0053] In order to improve the balancing effect of the balancer 10, in some embodiments, the balancer 10 further includes a plurality of partitions 200 and a plurality of balancing bodies 300, wherein the plurality of partitions 200 are spaced apart and distributed in the accommodating cavity to divide the accommodating cavity into a plurality of balancing cavities 102, and the partitions 200 and the inner wall of the balancing ring 100 form a flow gap 103, or the partitions 200 form a through hole 104 for the damping medium to pass through; and a plurality of balancing bodies 300 are arranged in the plurality of balancing cavities 102, wherein at least one balancing body 300 is arranged in the balancing cavity 102, and the balancing body 300 is movably matched with the balancing cavity 102 so that the balancing body 300 can move along the extension direction of the balancing cavity 102. In this embodiment, by arranging the balancing body 300, the balancing body 300 can play a balancing role together with the damping medium to improve the balancing effect of the balancer 10. The arrangement of the partition 200 limits the moving range of the balancing body 300 while not hindering the damping medium from flowing in different balancing chambers 102, effectively avoiding the situation where multiple balancing bodies 300 are concentrated to cause eccentric loads on the drum 20 when the eccentricity of the drum 20 is small, thereby ensuring the use effect of the balancing body 300. It is worth mentioning that the multiple balancing bodies 300 can be evenly arranged in multiple balancing chambers 102, or the number of balancing bodies 300 arranged in each balancing chamber 102 can be different, or at least one balancing body 300 can be arranged in some balancing chambers 102, and no balancing body 300 can be arranged in some balancing chambers 102, and no specific limitation is made here. In some embodiments, the partition 200 is arranged on the outer cavity wall of the accommodating chamber, and the partition 200 and the inner cavity wall of the accommodating chamber form the flow gap 103, the width of the flow gap 103 is W1, and the width of the balancing body 300 is W2, and W1 is smaller than W2. In this way, the movement of the balancing body 300 in the corresponding balancing chamber 102 is fully guaranteed.

[0054] Regarding the material of the balancing body 300, in some embodiments, the balancing body 300 is made of stainless steel. That is, the balancing body 300 is made of stainless steel to ensure that the balancing body 300 has a larger gravity under a smaller volume, thereby ensuring that a smaller number of balancing bodies 300 can also balance a larger eccentric load; in addition, stainless steel is not easy to rust, which ensures the service life of the balancing body 300, thereby ensuring the service life of the balancer 10.

[0055] In order to extend the service life of the balancer 10, in some embodiments, the separator 200 is elastic. For example, the separator 200 is made of rubber, silicone or other elastic materials. In this way, when the balancing body 300 hits the separator 200, the separator 200 can play a buffering effect so that the balancing body 300 and the separator 200 are not easily damaged, thereby ensuring the service life of the balancing body 300 and the separator 200, which is conducive to extending the service life of the balancer 10; at the same time, the balancing body 300 is not easy to be bounced off after the collision with the separator 200, thereby ensuring the stability of the movement of the balancing body 300, ensuring that the balancing body 300 can quickly and stably play a balancing role, and ensuring the use effect of the balancer 10.

[0056] In other embodiments, the separator 200 and the balancing body 300 are both magnetic, and the magnetic poles at the ends of the separator 200 are the same as the magnetic poles at the ends of the balancing body 300. In this way, the balancing body 300 and the separator 200 will not collide with each other by utilizing the principle of like poles repelling each other, thereby ensuring the service life of the balancing body 300 and the separator 200, thereby facilitating the extension of the service life of the balancer 10; at the same time, the moving range of the balancing body 300 is further limited, more effectively avoiding the situation where multiple balancing bodies 300 are concentrated to generate eccentric loads on the drum 20, thereby ensuring the balancing effect of the balancing body 300.

[0057] In order to further limit the moving range of the balancing body 300, in some embodiments, a connecting member 400 is provided in the balancing cavity 102, one end of the connecting member 400 is connected to the cavity wall of the balancing cavity 102, and the other end is connected to the balancing body 300. The connecting member 400 is connected to the balancing body 300, so that the connecting member 400 can limit the range of movement of the balancing body 300, so that the balancing body 300 moves within the preset range of movement, thereby further avoiding the situation where the balancing bodies 300 are gathered, and more effectively avoiding the situation where multiple balancing bodies 300 are concentrated to cause the drum 20 to generate eccentric loads, thereby improving the balancing effect of the balancer 10. Further, the connecting member 400 is elastic, the connecting member 400 is a spring, or the connecting member 400 is an elastic strip, such as a rubber strip, etc. The connecting member 400 is elastic so that the connecting member 400 can produce elastic deformation, and can absorb the pulling force generated by the balancing body 300 on the connecting member 400, thereby reducing the reaction force generated by the connecting member 400 on the balancing body 300, and preventing the balancing body 300 from being instantly subjected to excessive reaction force and being rebounded, thereby ensuring that the balancing body 300 can stably move in the accommodating cavity, thereby ensuring that the balancing body 300 can quickly and stably play a balancing role, and further ensuring the balancing effect of the balancer 10.

[0058] Reference Figure 6 The present invention also proposes a clothing care device, comprising a drum 20, a storage box 50, a transmission tube 30, a main control circuit, a driving device electrically connected to the main control circuit, and the above-mentioned balancer 10, wherein the balancer 10 is sleeved on the drum 20, the storage box 50 is used to store damping medium, the two ends of the transmission tube 30 are respectively connected to the storage box 50 and the through hole 101 of the balancer 10, and the driving device is connected to the transmission tube 30, so that the damping medium in the storage box 50 enters the accommodating cavity under the drive of the driving device, or the damping medium in the accommodating cavity is led out to the storage box 50 under the drive of the driving device. The clothing care device can be a washing machine, a clothing care machine, a washing and drying machine, etc. for caring for clothing. The driving device can be a motor, a water pump, etc. The driving device is connected to the main control circuit, so that the main control circuit controls the driving device to drive the damping medium in the storage box 50 into the accommodating cavity, or controls the driving device to make the damping medium in the accommodating cavity flow out of the accommodating cavity and flow into the storage box 50. In this way, the amount of damping medium in the accommodating chamber can be adjusted, so that the amount of damping medium in the accommodating chamber can be controlled accordingly according to the weight of the clothes in the drum 20 and the rotation speed of the drum 20 to ensure the balancing effect of the balancer 10.

[0059] Specifically, one end of the transmission tube 30 is connected to the through hole 101, and the other end of the transmission tube 30 extends along the drum 20 and passes through the drum rotating shaft, and the other end of the transmission tube 30 is communicated with a first cavity provided in the drum rotating shaft; the clothing care device also includes a slip ring, and the slip ring includes a slip ring rotor 61 and a slip ring stator 62, and the slip ring rotor 61 is connected to the drum rotating shaft to rotate with the drum rotating shaft, and the slip ring rotor 61 is provided with a second cavity communicated with the first cavity, and the slip ring stator 61 is provided with There are an injection port 63 and an extraction port 64 respectively connected to the second cavity, and the injection port 63 and the extraction port 64 are respectively connected to the storage box 50; the driving device includes a first driving device 41 and a second driving device 42, the first driving device 41 is arranged between the injection port 63 and the storage box 50, and is used to drive the damping fluid from the storage box 50 to move to the injection port 63, and the second driving device 42 is arranged between the extraction port 64 and the storage box 50, and is used to drive the damping fluid from the extraction port 64 to the storage box 50.

[0060] In actual use, the load in the drum 20 comes from the weight of the clothes. The user may obtain the weight of the clothes in the drum 20 and then operate the control panel to trigger the main control circuit to control the drive device to adjust the amount of the damping medium in the accommodating chamber according to the user's selection. Alternatively, the main control circuit can obtain the load in the drum 20 and then automatically control the drive device to adjust the amount of the damping medium in the accommodating chamber according to the current load. For example, in some embodiments, the clothing care device further includes a gravity sensor, which is electrically connected to the main control circuit and is installed on the drum 20 to sense the load in the drum 20. The gravity sensor obtains the load signal in the drum 20 and transmits the load signal to the main control circuit so that the main control circuit can obtain the load in the drum 20.

[0061] In some embodiments, the clothing care device further includes a speed sensor, which is electrically connected to the main control circuit and is mounted on the drum 20 to sense the rotation speed of the drum 20. It is understandable that the centrifugal force generated by the clothes in the drum 20 is related to the rotation speed of the drum 20, so the required balancing force of the balancer 10 is related to the rotation speed of the drum 20. By setting a speed sensor to obtain the rotation speed signal of the drum 20, and then sending the rotation speed signal to the main control circuit, the main control circuit can reasonably control the driving device to adjust the amount of the damping medium in the accommodating cavity according to the rotation speed of the drum 20, so as to ensure the balancing effect of the balancer 10.

[0062] The present invention also provides a control method for a clothing care device, referring to Figures 7 to 9 In some embodiments, a method for controlling a clothing care device includes:

[0063] S10, obtaining the current load in the drum 20;

[0064] S20, obtaining a target volume of the damping medium required in the accommodating cavity according to the current load;

[0065] S30, adjusting the volume of the damping medium in the accommodating cavity according to the target volume;

[0066] S40, driving the drum 20 to rotate.

[0067] In step S10, the load in the drum 20 comes from the weight of the clothes. There are many ways to obtain the current load in the drum 20. For example, the clothes can be weighed manually, or a gravity sensor can be installed on the drum 20. The gravity sensor is connected to the main control circuit. In this way, the gravity sensor can sense the load in the drum 20, and then transmit the load information to the main control circuit, so that the main control circuit can obtain the load in the drum 20.

[0068] In step S20, it can be understood that, during the rotation of the drum 20, its rotation speed will have an acceleration process from zero to reach a high speed, and then after running at a high speed for a period of time, it will decelerate from a high speed to a low speed until it stops rotating. During the rotation of the drum 20, the clothes in the drum 20 will have a centrifugal force on the drum 20. At the beginning of the low-speed operation, because the speed is relatively low, the centrifugal force of the clothes is relatively small, and the force on the drum 20 is relatively small, so that the eccentric force of the drum 20 is relatively small; when the drum 20 rotates at a high speed, the centrifugal force of the drum 20 is much greater than the weight of the clothes. At this time, the weight of the clothes and the distribution of the clothes in the drum 20 have little effect on the drum 20, so that the eccentricity of the drum 20 is also relatively small, that is, the eccentricity of the drum 20 is relatively small in the initial low-speed state and the high-speed uniform speed operation stage. However, in the medium-speed stage between low speed and high speed, the centrifugal force of the clothes exerts a greater squeezing force on the drum 20, resulting in a greater eccentricity of the drum 20 and a greater balancing force required for the drum 20. In this stage, the greater the load in the drum 20, that is, the greater the weight of the clothes, the greater the centrifugal force generated, the greater the balancing force required for the drum 20, and the greater the weight of the required damping medium. Therefore, the required balancing force can be obtained according to the current load of the drum 20 to obtain the required weight of the damping medium, and then according to the formula that volume is equal to mass divided by density, when the damping medium is determined, the target volume of the required damping medium can be calculated.

[0069] It is worth mentioning that a load-volume mapping table can be pre-stored in the main control circuit, that is, the load value in the drum 20 has a corresponding target volume value of the damping medium. In this way, after the main control circuit obtains the current load in the drum 20, it can obtain the target volume of the damping medium required in the containing cavity through the load-volume mapping table.

[0070] Of course, in other embodiments, in order to more accurately balance the drum 20, step S20 may include:

[0071] S21, obtaining the current working mode of the clothing care device;

[0072] S22, obtaining a preset rotation speed of the drum 20 according to the current working mode;

[0073] S23. Obtaining a target volume of the damping medium according to the current load and a preset rotation speed.

[0074] In steps S21 and S22, the working mode of the clothing care device can be a washing mode, a spin mode, a drying mode, etc. It can be understood that the rotation speed of the drum 20 may be different for each different working mode. The current working mode of the clothing care device can be obtained through the main control circuit, and then the preset rotation speed of the drum 20 is obtained according to the current working mode.

[0075] In step S23, it can be understood that during the rotation of the drum 20, its rotation speed will have an acceleration process from zero to reach a high speed, and then after running at a high speed for a period of time, it will decelerate from high speed to low speed until it stops rotating. When the drum 20 is in the low-speed and high-speed rotation stages, the balancing force required by the drum 20 is relatively small, and in the medium-speed stage between the low speed and the high speed, the balancing force required by the drum 20 is relatively large, so at the critical speed between the medium-speed and high-speed stages, the required balancing force is the largest, so when calculating the balancing force, the required maximum balancing force should be calculated based on the speed of the critical speed, and the clothing care device has different preset speeds in different working modes, that is, the maximum speed is different, and the critical speed will be different, so the critical speed can be obtained by obtaining the preset speed, and then combined with the current load in the drum 20, the weight of the damping medium required in the accommodating cavity is obtained, and then according to the formula that volume is equal to mass divided by density, when the damping medium is determined, the target volume of the required damping medium is calculated.

[0076] Similarly, a load, speed-volume mapping table can be pre-stored in the main control circuit, that is, after obtaining the current load in the drum 20 and the preset speed of the drum 20, the main control circuit can obtain the target volume of the damping medium required in the accommodating cavity through the load, speed-volume mapping table.

[0077] In step S30, the main control circuit may include a storage circuit for storing the volume of the damping medium in the accommodating cavity adjusted each time, so that the main control circuit can obtain the volume of the damping medium in the current accommodating cavity. Specifically, step S30 includes:

[0078] S31, obtaining the current volume of the damping medium in the accommodating cavity;

[0079] S32, comparing the target volume and the current volume, and calculating the adjustment volume required for adjustment;

[0080] S33. Adjust the volume of the damping medium in the accommodating cavity according to the adjustment volume.

[0081] In step S40, the main control circuit controls the driving motor connected to the drum 20 to operate in a preset mode, so that the drum 20 starts to rotate in the preset working mode.

[0082] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
