In the description of the present disclosure, unless otherwise stated, "a plurality" means two or more.

The laundry processing apparatus 1000 according to an embodiment of the present disclosure is described below with reference to FIGS. 1 to 36.

Referring to FIG. 1 to FIG. 3, a laundry treatment apparatus 1000 according to some embodiments of the present disclosure may include a treatment cylinder device 100, a device housing 200, a driving device 300, a control system, and the like. The processing cylinder device 100 may be disposed in the equipment casing 200, and a door assembly 400 may be provided on the equipment casing 200 to open and close the processing cylinder device 100. The equipment housing 200 is an optional component. For example, in some optional embodiments, the processing cylinder device 100 may be directly exposed or embedded in a wall or cabinet.

As shown in FIG. 2, the driving device 300 may be a driving motor, such as a direct drive motor, to drive the processing cylinder device 100 to operate under the control of a control system. Optionally, the door assembly 400 is connected to the front portion of the processing cylinder device 100, and the driving device 300 is connected to the rear portion of the processing cylinder device 100, which is more in line with operating habits. At the same time, the driving device 300 can be hidden and the driving effect is better.

According to some embodiments of the present disclosure, as shown in FIG. 2, the processing cylinder device 100 may include an outer cylinder 30, an inner cylinder 20, and a gimbal ring assembly 10. The inner cylinder 20 is disposed in the outer cylinder cavity 310 of the outer cylinder 30. The inner cylinder 20 has a horizontal or inclined rotation axis, that is, the rotation axis of the inner cylinder 20 is parallel to or inclined to the horizontal plane. The balance ring assembly 10 is located in the outer cylinder cavity 310 of the outer cylinder 30. The balance ring assembly 10 includes a balance ring 1 and a water injection member 2. The balance ring 1 is connected to the inner cylinder 20 to rotate with the inner cylinder 20.

The center axis of the balance ring 1 is parallel or coincident with the rotation axis of the inner cylinder 20, that is, the balance ring 1 may be disposed coaxially with the inner cylinder 20 or eccentrically with respect to the inner cylinder 20. In order to ensure that the balance ring 1 has a good balance effect on the inner cylinder 20, when the balance ring 1 is eccentrically set, the value of the eccentric distance may be smaller. The distance from the rotation axis of the inner cylinder 20 may be set to 5 mm or less, for example, 2 mm, 3 mm, and the like.

The water injection member 2 can inject water into the balance ring 1 so that the center of gravity of the balance ring 1 is changed, so as to adjust the eccentricity of the inner cylinder 20 and play a role in adjusting balance. Optionally, the control system may be connected to the water injection member 2 to control the water injection member 2 to actively inject water into the balance ring 1, so that the laundry processing apparatus 1000 has an active balance control function.

Optionally, referring to FIGS. 2 to 6, the water injection member 2 may be installed on the outer cylinder 30, and when the inner cylinder 20 drives the balance ring 1 to rotate, the water injection member 2 may remain stationary, which not only facilitates manufacturing and installation, And more stable water injection can be achieved. The related structure of the water injection member 2 will be described in detail later. The related structure of the gimbal ring 1 will be further described below.

As shown in FIGS. 7 to 12, in some embodiments of the present disclosure, the balance ring 1 includes a ring-shaped body 11 with a cavity 101 therein, and the inner peripheral surface of the balance ring 1 has a water inlet 102. The water injection member 2 injects water into the balance ring, and the water flow from the water injection port of the water injection member 2 enters the chamber 101 through the water inlet 102. Optionally, the water inlet 102 extends along the circumferential direction of the body 11, that is, the water inlet 102 is a circular port provided on the inner peripheral surface of the body 11. Therefore, when the balance ring 1 is rotating, the water injection member 2 can conveniently inject water into the chamber 101 through the annular water inlet 102, and the water entering the chamber 101 will be directed to the outer wall surface of the chamber 101 under the action of centrifugal force. When the balance ring 1 stops rotating, water can flow out through the water inlet 102 under the effect of gravity, and the drainage effect is better.

It can be understood that the cavity 101 in the balance ring 1 can be set to different structures to achieve the effect of adjusting the eccentricity of the load through water injection. The related structure of the balance ring 1 is further described below with reference to some embodiments.

7 to 12 show a gimbal 1 according to a first specific embodiment of the present disclosure. As shown in FIGS. 7 to 12, the number of the chambers 101 may be three, and the three chambers 101 are distributed along the circumferential direction of the body 11. Therefore, the balance control can be achieved by controlling the water injection amount in the three chambers 101, and the control effect is better.

With continued reference to FIGS. 7 to 12, the inner peripheral surface of the main body 11 may be provided with three water channel grooves 103. The three water channel grooves 103 respectively extend in the circumferential direction of the main body 11 and are arranged along the axial direction of the main body 11. The three waterway grooves 103 communicate with the three chambers 101 one-to-one, and the bottom wall surface 1031 of each waterway groove 103 has three openings 104 to communicate the waterway groove 103 and the corresponding chamber 101. Therefore, the control of the water injection amount of the three chambers 101 can be achieved by controlling the water injection amount of the three water channel grooves 103. When the required water amount is injected into the corresponding chamber 101, the corresponding water injection member 2 can be used to The water channel tank 103 is filled with the required amount of water, the water injection is more targeted, the balance response to the eccentric load is faster, the adjustment efficiency is higher, and the time for processing clothes can be effectively shortened.

According to some embodiments of the present disclosure, the number of the chambers 101 and the water channel grooves 103 are not limited to three as described above, and the number of the chambers 101 and the water channel grooves 103 can also be set to Other values, such as two, four, or more. In addition, the number of the chambers 101 and the water channel grooves 103 may be the same, and the relationship may be one to one, or the number of the chambers 101, and the water channel grooves 103 may be different.

For example, the number of water tanks 103 may be greater than the number of chambers 101. Some of the chambers 101 communicate with one water tank 103, and other chambers 101 communicate with at least two water tanks 103, that is, the water tank 103 and the chamber. 101 is a many-to-one relationship.

As another example, in some optional embodiments of the present disclosure, the number of the water channel grooves 103 is greater than the number of the chambers 101. The plurality of water channel grooves 103 include a special water channel groove communicating with only one chamber 101 and at least two chambers. Each of the chambers 101 may have a dedicated waterway groove communicating with the chamber 101. Therefore, when it is necessary to inject water into one chamber 101, it is possible to control the injection of water into the corresponding special waterway tank, and other special waterway tanks and public waterway tanks. When it is necessary to inject water into at least two chambers 101, not only the corresponding The water inlet of the special water channel can also control the water injection of the public water channel, which is in communication with at least two chambers 101 that need water injection.

For another example, in other optional embodiments of the present disclosure, each water channel groove 103 is in communication with all the chambers 101, and each water channel groove 103 is in a different size with the opening 104 communicating with multiple chambers 101, so that the water channel The tank 103 can inject different amounts of water into the plurality of chambers 101 respectively, thereby achieving balance adjustment.

In this regard, for the convenience of description, referring to FIG. 9 to FIG. 12 as examples, there are three water channel grooves 103, namely a first water channel groove 113, a second water channel groove 123, and a third water channel groove 133, and three chambers 101 are respectively The first chamber 111, the second chamber 121, and the third chamber 131 can set the size of the opening 104 of the first waterway groove 113 for communicating with the first chamber 111 to be larger and the same as the second chamber. The size of the opening 104 communicating with 121 and the third chamber 131 is set smaller, and the size of the opening 104 of the second watercourse groove 123 for communicating with the second chamber 121 is set to be larger and the first chamber 111 The size of the opening 104 communicating with the third chamber 131 is set to be small, and the size of the opening 104 of the third waterway groove 133 for communicating with the third chamber 131 is set to be larger and communicate with the first chamber 111 and The size of the opening 104 communicating with the second chamber 121 is relatively small.

Therefore, when the water injection into a certain chamber 101 is mainly required, the water injection into the corresponding water channel groove 103 with a large water injection volume can be controlled. For example, when the water injection into the first chamber 111 is mainly performed, the water injection into the first water channel groove 113 can be controlled.

Those skilled in the art can understand that in addition to controlling the number of the water channel grooves 103 communicating with the chamber 101, the size of the opening 104 of the water channel groove 103 communicating with the plurality of chambers 101, and other methods, it is possible to realize by controlling the plurality of water channel grooves 103 In addition to adjusting the amount of water injected into each chamber 101, the plurality of water channel grooves 103 can also be set to other structural forms, as long as it can satisfy The requirements for the adjustment of the water injection amount of the individual chambers 101 are sufficient, and details are not described herein again.

In addition, in the embodiments shown in FIG. 7 to FIG. 12, the plurality of chambers 101 may be completely staggered in the circumferential direction of the body 11, that is, the portions where any two chambers 101 do not overlap in the circumferential direction of the body 11, in other words, There are no two chambers 101 at any position in the circumferential direction of the body 11, and if there is only one chamber 101. Thereby, the effect of balance adjustment can be improved.

Of course, the present disclosure is not limited to this. The plurality of chambers 101 may also be staggered along the circumferential direction of the body 11, that is, two adjacent chambers 101 may extend to the same position in the circumferential direction of the body 11. The adjacent chambers 101 also extend to different positions in the circumferential direction of the body 11, respectively.

According to the gimbal ring 1 of the embodiment of the present disclosure, a plurality of chambers 101 distributed in the circumferential direction are provided in the body 11, and a plurality of water channel grooves 103 extending in the circumferential direction are provided on the inner peripheral surface of the body 11. Water is injected into the corresponding chambers 101. The amount of water injected into each chamber 101 can be adjusted by controlling the state of water injection into a plurality of water channel grooves 103, so that the weight distribution of the balance ring 1 in the circumferential direction can be adjusted, and the load can be adjusted. And finally reach balance adjustment.

As shown in FIGS. 10 to 12, the three openings 104 communicating with the water channel groove 103 and each of the chambers 101 may be spaced apart along the circumferential direction of the main body 11, so that the water intake is smoother and more uniform. It can be understood that the number of openings 104 communicating with the water channel groove 103 and each of the chambers 101 is not limited to three, and may be other numbers, for example, one, two, four, etc., which can be flexibly set according to actual needs.

With continued reference to FIGS. 10 to 12, the three chambers 101 may have the same volume and the same shape, which is not only convenient for manufacturing, but also easier to adjust the balance. According to some embodiments of the present disclosure, when the number of the chambers 101 is other, the multiple chambers 101 may still be set to have the same volume and the same shape. Of course, the present disclosure is not limited to this, and the plurality of chambers 101 may be set to have different volumes and shapes according to needs.

Optionally, according to some embodiments of the present disclosure, the depth direction of each waterway groove 103 and the orientation of the notch (ie, the water inlet 102) of each waterway 103 are perpendicular to the axial direction of the body 11. In other words, the direction of the groove bottom wall surface 1031 of the waterway groove 103 is approximately the extension direction of the radial section of the body 11, and the direction of the groove is also approximately the extension direction of the radial section of the body 11. Thus, the waterway groove The groove bottom wall surface 1031 of the groove 103 is approximately facing the center of the body 11, which not only makes it easier for water to enter the groove, but also allows water to enter the chamber 101 through the water channel groove 103 more quickly and smoothly. Improved regulation efficiency.

13 to 15 show a gimbal 1 according to a second specific embodiment of the present disclosure. The structure in this specific embodiment is substantially the same as the structure in the first specific embodiment, and the difference is mainly in the structure of the notch of the waterway tank 103. As shown in FIGS. 13 to 15, the edge of the notch (that is, the water inlet 102) may be provided with a water retaining rib 105. When water is sprayed on the inner wall surface of the body 11, a certain splash may be caused, and the water retaining rib 105 may be provided. The splash is effectively reduced, the water sprayed by the water injection member 2 is not easily splashed, and the water injection efficiency is improved.

The present disclosure does not specifically limit the specific structure of the water retaining rib 105 as long as it can meet the requirement of forming a certain suppression effect on the splash of water. Optionally, taking the embodiment shown in FIG. 14 as an example, the arrangement of the water retaining rib 105 can make the notch roughly formed into a contraction structure, and the water entering the groove can be blocked by the water retaining rib 105, and it is not easy to splash outward. Out. Optionally, in this embodiment, the water retaining rib 105 is a flange extending from the edge of the slot along the axial direction of the body 11 into the slot, so that the structure is not only easy to manufacture, makes the appearance more regular and beautiful, but also avoids splashing. The effect is better.

Of course, the water retaining rib 105 may also be provided as a flange extending obliquely to the axial direction of the body 11 and extending into the slot. The flange may extend along a straight line or along a curve. Optionally, as shown in FIG. 19, the water retaining rib 105 can also be provided as a protrusion provided on the edge of the slot, and this structure can also play a role of preventing splashing.

In addition, in order to eliminate the splash and reduce the influence on the water, the protruding size of the water retaining rib 105 in the slot is not easy to be too large. For example, the protruding size can be set within 3 mm, for example, 1 mm or 2 mm.

Optionally, the water retaining rib 105 may be an integral part with the main body 11, or may be a separate piece assembled integrally with the main body 11. The water retaining rib 105 may be flexibly provided according to the actual situation.

As shown in FIG. 19, in some embodiments of the present disclosure, the depth h of the water channel groove 103 may be set to 5 mm or more. This arrangement ensures a sufficient depth of the water channel groove 103 and also plays a role of preventing splashing.

16 to 20 show a gimbal ring 1 according to a third specific embodiment of the present disclosure. The structure in this specific embodiment is substantially the same as that in the second embodiment, and the difference is mainly in the structure of the inner wall surface of the chamber 101. In short, in this specific embodiment, the structure of the chamber 101 is optimized. The corners of the chamber 101 are chamfered to make it easier for water in the balance ring 1 to drain, and at the same time, it can enter the balance ring 1 during the washing process. The fouling inside is very easy to discharge.

As shown in FIG. 16, FIG. 17, and FIG. 19, optionally, an inner wall surface of the chamber 101 at both ends in the axial direction of the body 11 and an inner wall surface of the chamber 101 at the inner end in the radial direction of the body 11 are optionally formed. There is an axial end inside angle 106, that is, the angle formed by the connection between the cavity side wall surface 1011 of the cavity 101 and the cavity bottom wall surface 1012 of the cavity 101 is the axial end inside angle 106. Optionally, the axially inner side angles 106 at both ends of the chamber 101 are chamfered. This structure can weaken the dead corner area in the cavity 101, avoid the accumulation of hair debris, and make the inner wall surface of the cavity 101 smoother, thereby facilitating the discharge of water and hair debris.
