Description

Technical Field

[0002] In the related art, most clothing treatment devices (such as washing machines, dryers, integrated washing and drying machines, etc.) are usually provided with a valve body structure for realizing the infusion control function of the transmission process of clothing treatment agents such as care agents or detergents. At the same time, in order to meet the needs of continuous clothing treatment, these devices are also equipped with a special liquid adding structure, so that users can easily add clothing treatment agents. However, in the traditional design, the valve body structure and the liquid adding structure are independent components, which means that the two need to occupy different installation spaces inside the clothing treatment device, which not only increases the overall volume of the clothing treatment device, but also leads to an increase in material costs due to the need to manufacture and install two independent components separately, which is not conducive to product cost control and market competitiveness.

[0057] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0058] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0059] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0061] See also Figure 1 In the first aspect of the present application, a clothes processing device 1000 is provided. The clothes processing device 1000 may be a washing machine, a clothes dryer, a washer-dryer, etc., for washing and dehydrating various types of clothes. Of course, the clothes processing device 1000 may also include a shoe washing machine for washing shoes.

[0062] In the related art, most clothing treatment devices (such as washing machines, dryers, integrated washing and drying machines, etc.) are usually provided with a valve body structure for realizing the infusion control function of the transmission process of clothing treatment agents such as care agents or detergents. At the same time, in order to meet the needs of continuous clothing treatment, these devices are also equipped with a special liquid adding structure, so that users can easily add clothing treatment agents. However, in the traditional design, the valve body structure and the liquid adding structure are independent components, which means that the two need to occupy different installation spaces inside the clothing treatment device, which not only increases the overall volume of the clothing treatment device, but also leads to an increase in material costs due to the need to manufacture and install two independent components separately, which is not conducive to product cost control and market competitiveness.

[0063] To solve the above problems, please refer to Figures 2 to 4 In a second aspect of the present application, a valve assembly 100 is proposed. The valve assembly 100 can be applied to the aforementioned clothing processing device 1000, and can also be applied to a non-clothing processing device that needs to have both an infusion function and a liquid adding function. The following is an example of the valve assembly 100 being applied to the clothing processing device 1000. In an embodiment of the present application, the valve assembly 100 includes a valve body 10, a valve core 20, and an operating member 30.

[0064] The valve body 10 is provided with a liquid inlet 12A and a liquid outlet 12B. Specifically, two outwardly protruding pipe components can be provided on the periphery of the valve body 10, and the two pipe components are respectively connected with the liquid inlet 12A and the liquid outlet 12B, and the pipe components are used to facilitate communication with other pipe channels of the clothing treatment device 1000, so as to realize the flow transmission of clothing treatment agent in the valve assembly 100.

[0065] The valve core 20 is arranged in the valve body 10, and the valve body 10 has a liquid adding channel 10A or the valve body 10 and the valve core 20 cooperate to form the liquid adding channel 10A. It can be understood that the liquid adding channel 10A is used for the clothes treating agent to flow through, so as to supplement the clothes treating agent to the clothes treating device 1000. By directly forming the liquid adding channel 10A by the valve body 10, the sealing performance is better, and the possibility of fluid leakage is reduced. By cooperating with the valve body 10 and the valve core 20 to form the liquid adding channel 10A, the size and shape of the liquid adding channel 10A can be flexibly changed by adjusting the position and shape of the valve core 20 to adapt to different flow and pressure requirements. In addition, the valve body 10 and the valve core 20 can be made of non-metallic materials such as plastic materials. First, non-metallic materials such as plastics are lighter than metal materials, which can effectively reduce the overall mass of the valve assembly 100, making installation and operation more convenient. Secondly, non-metallic materials such as plastics have excellent corrosion resistance, which can avoid the problem of rust after long-term contact with clothes treating agents.

[0066] The operating member 30 is connected to the valve core 20, and the operating member 30 is suitable for performing a first movement relative to the valve body 10 to drive the valve core 20 to connect or block the liquid inlet 12A and the liquid outlet 12B. Specifically, when the liquid inlet 12A and the liquid outlet 12B need to be blocked, the operating member 30 performs a first movement to drive the structure inside the valve core 20 or the valve body 10 as a whole to move relative to the valve body 10, so as to tightly cover at least one of the liquid inlet 12A and the liquid outlet 12B, ensuring that the clothes treatment agent in the liquid inlet 12A cannot flow through the liquid outlet 12B. At this time, an effective blocking state is formed between the liquid inlet 12A and the liquid outlet 12B, thereby avoiding leakage and misflow of the clothes treatment agent. When it is necessary to allow the laundry treatment agent to flow freely between the liquid inlet 12A and the liquid outlet 12B, the user operates the operating member 30 again, and the partial structure inside the valve core 20 or the valve core 20 as a whole will move to the non-blocking position accordingly, and no longer block the liquid inlet 12A and the liquid outlet 12B. At this time, the laundry treatment agent in the liquid inlet 12A can flow out smoothly through the liquid outlet 12B, achieving the communication state between the liquid inlet 12A and the liquid outlet 12B, meeting the needs of transmitting and using the laundry treatment agent.

[0067] It should be noted that the driving mode of the operating member 30 is diverse and flexible. It can be electrically driven to achieve automatic control, or it can be directly manually operated according to user needs. In the electric drive mode, the operating member 30 receives a control signal through a motor or other electrical device, and accurately performs a first movement relative to the valve body 10 to control the valve core 20 to achieve rapid on and off of the liquid. This automated control method not only improves work efficiency, but also can achieve precise liquid flow control in specific situations to meet different application requirements. In the manual operation mode, the user can directly operate the operating member 30, such as rotating or pulling, to manually control the valve core 20. This method is simple and easy to use, does not require a complex control system, and effectively saves costs.

[0068] In addition, the operating member 30 is provided with a sealing portion 31, wherein only the sealing portion 31 may perform a second movement relative to the valve body 10 to seal or open the liquid adding channel 10A, or the operating member 30 as a whole may perform a second movement relative to the valve body 10 to seal or open the liquid adding channel 10A.

[0069] Based on the above embodiments, the valve assembly 100 proposed in the embodiment of the present application includes a valve body 10, a valve core 20 and an operating member 30. Through the synergistic effect of the three, the infusion control function and the liquid adding function are realized at the same time. Specifically, the valve core 20 is arranged inside the valve body 10 and is connected to the operating member 30, and the valve body 10 has a liquid adding channel 10A or the valve body 10 and the valve core 20 cooperate to form a liquid adding channel 10A. In this way, the user controls the operating member 30 to perform a first movement relative to the valve body 10 to drive the valve core 20 to achieve the connection or isolation between the liquid inlet 12A and the liquid outlet 12B, thereby realizing the infusion control of the clothing treatment agent in the valve assembly 100. At the same time, the operating member 30 also includes a capping part 31. When it is necessary to add the clothing treatment agent, the user controls the capping part 31 to perform a second movement relative to the valve body 10 to open the liquid adding channel 10A, and then directly adds the clothing treatment agent through the liquid adding channel 10A. After the liquid addition is completed, the capping part 31 can be driven to re-cap the liquid adding channel 10A. In this way, the liquid adding function and the liquid on-off control function can be combined in the same valve assembly 100, so that there is no need to occupy additional space in the clothing treatment device 1000 to install an independent liquid adding structure, which effectively reduces the overall space occupation and the number of parts, thereby reducing the material cost. At the same time, this compact design also reduces the manufacturing cost and maintenance cost of the clothing treatment device 1000, further improving the cost performance of the product and bringing users a more convenient and economical use experience.

[0070] See also Figures 2 to 4In some structural forms, the liquid adding channel 10A has a liquid adding port 10a communicating with the outside on the surface of the valve body 10, and at least the sealing portion 31 is suitable for performing a second movement relative to the valve body 10 to seal or open the liquid adding port 10a. In this way, when it is necessary to add additional clothing treatment agent, the user can at least make the sealing portion 31 perform the second movement to quickly and accurately expose the liquid adding port 10a to the outside, so that the user can directly add clothing treatment agent to the liquid adding channel 10A through the liquid adding port 10a, making the liquid adding process more convenient, and allowing the user to quickly understand the state of the liquid adding channel 10A being sealed or opened.

[0071] Furthermore, the operating member 30 also includes a connecting portion 32 connected to the cover portion 31, wherein the cover portion 31 and the connecting portion 32 can be an integral structure to ensure overall strength. Or the two can also be connected in a detachable manner such as screws and snaps to facilitate later individual maintenance and replacement needs. The operating member 30 has a rotation axis passing through the connecting portion 32 and the cover portion 31. The connecting portion 32 is connected to the valve core 20, and the first movement is the rotation of the connecting portion 32 around the rotation axis, and drives the valve core 20 to rotate relative to the valve body 10, so that the valve core 20 can move relative to the valve body 10 to connect or disconnect the liquid inlet 12A and the liquid outlet 12B. It should be noted that this rotation can be a single rotation of the connecting portion 32, or it can be a rotation of the operating member 30 as a whole. This design is extremely flexible and can adapt to different operating requirements and working environments.

[0072] The second movement is the movement of the cover part 31 moving along the axial direction of the rotation axis to realize the opening and closing of the liquid adding port 10a. Specifically, the cover part 31 can move outward from the liquid adding port 10a, so as to open the liquid adding port 10a and facilitate the addition of clothing treatment agent. Alternatively, the cover part 31 can also move along the rotation axis toward the inside of the liquid adding channel 10A to also achieve the purpose of opening the liquid adding port 10a. In this way, the two movement modes of rotation and axial movement are used to respectively realize the infusion control and liquid adding functions. The operating member 30 can not only realize the precise control of the valve core 20, but also can conveniently realize the liquid adding operation. This design not only improves the convenience of operation, but also makes the entire valve assembly 100 more efficient and reliable.

[0073] In addition, the operating member 30 may further include a control portion 33, which is connected to one end of the cover portion 31 away from the connection portion 32, so that the user can hold and control it. This can drive the operating member 30 to move as a whole or drive the cover portion 31 or the connection portion 32 to move separately. The control portion 33 can be a convex block 241 structure, and the surrounding side of the convex block 241 structure can be equipped with anti-slip texture or groove 1221 to increase the friction when holding and prevent slipping during operation.

[0074] See also Figures 2 to 4 In one embodiment, the valve body 10 includes a valve shell 11 and a valve body 12. The valve shell 11 has an installation cavity 111 and is connected to the outside through a liquid adding port 10a. The valve body 12 is partially or completely arranged in the installation cavity 111. The valve body 12 has a valve cavity 121 and a liquid inlet 12A and a liquid outlet 12B connected to the valve cavity 121. Among them, the valve shell 11 and the valve body 12 can be connected in a detachable manner such as screws or snaps to facilitate later maintenance and replacement. The valve core 20 is movably arranged in the valve cavity 121 and has a liquid adding cavity 21, and the installation cavity 111 and the liquid adding cavity 21 are connected to form a liquid adding channel 10A. That is, when the clothing treatment agent is added from the installation port, the clothing treatment agent flows through the installation cavity 111 and the liquid adding cavity 21 in sequence. The cover part 31 is detachably connected to the valve housing 11. When it is necessary to open the liquid filling port 10a to add clothing treatment agent, the user only needs to easily remove the cover part 31 from the valve housing 11 to fully expose the liquid filling port 10a, so as to avoid the cover part 31 affecting the liquid filling process. Specifically, when the liquid inlet 12A is connected to the liquid outlet 12B, the cover part 31 is locked with the valve housing 11, and when the liquid inlet 12A is separated from the liquid outlet 12B, the cover part 31 can be removed relative to the valve housing 11. In this way, the cover part 31 can only be removed from the valve housing 11 when the liquid inlet 12A is separated from the liquid outlet 12B. When the liquid inlet 12A is connected to the liquid outlet 12B, the cover part 31 cannot be removed for liquid filling, thereby ensuring the stability of the transmission of the clothing treatment agent.

[0075] Optionally, the side wall of the mounting cavity 111 is provided with an internal thread 1111, and the outer wall of the cover portion 31 is provided with an external thread 311 for matching and connecting with the internal thread 1111. In this way, the cover portion 31 and the valve housing 11 are connected by threads to achieve detachability. Not only is the tight connection between the cover portion 31 and the valve housing 11 ensured, thereby ensuring the sealing and stability of liquid transmission. At the same time, through a simple rotation action, the user can easily achieve the locking and separation of the cover portion 31 and the valve housing 11, which greatly improves the convenience of the disassembly operation. Of course, the cover portion 31 and the valve housing 11 can also be detachably connected by means of snap fasteners or the like, which can be specifically selected according to those skilled in the art.

[0076] In another structural form, the connection part 32 is detachably connected to the valve core 20. It should be noted that the connection part 32 can be detachably connected to the valve core 20 alone. In this mode, when it is necessary to open the liquid filling port 10a with the sealing part 31, the user removes the connection part 32 from the valve core 20, so that the connection part 32 can drive the sealing part 31 to move along the axial direction of the rotation axis at the same time, thereby realizing the opening of the liquid filling port 10a, and facilitating the user to replenish the clothing treatment agent through the liquid filling port 10a. When the liquid inlet 12A is connected to the liquid outlet 12B, the connection part 32 is locked with the valve core 20, and when the liquid inlet 12A is separated from the liquid outlet 12B, the connection part 32 can be removed relative to the valve core 20. In this way, the connecting part 32 can be removed from the valve housing 11 only when the liquid inlet 12A and the liquid outlet 12B are isolated. When the liquid inlet 12A and the liquid outlet 12B are connected, the connecting part 32 cannot be separated from the valve core 20 for liquid addition, thereby ensuring the stability of the transmission of the clothing treatment agent.

[0077] In addition, in another structural form, the operating member 30 can also be detachably connected to the valve body 10 and the valve core 20 at the same time. That is, the cover portion 31 of the operating member 30 is detachably connected to the valve body 12, and the connecting portion 32 is detachably connected to the valve core 20 at the same time. In this way, the above arrangement allows the user to open the liquid filling port 10a only when the operating member 30 needs to be separated from the valve body 10 and the valve core 20 at the same time. This design improves the stability of the installation of the operating member 30 to prevent the liquid filling port 10a from being easily opened.

[0078] See also Figures 3 to 5 Further, the connecting portion 32 is provided with one of the clamping groove 323 and the clamping block 25 matched with the clamping groove 323, and the valve core 20 is provided with the other of the clamping groove 323 and the clamping block 25. The connecting portion 32 and the valve core 20 are plugged and fixed by the clamping groove 323 and the clamping block 25, so that the connecting portion 32 can drive the valve core 20 to rotate relative to the valve body 10. That is, the connecting portion 32 and the valve core 20 are connected by clamping to achieve a detachable connection. Specifically, when the connecting portion 32 is provided with the clamping groove 323, the clamping block 25 on the valve core 20 is inserted into the clamping groove 323 to form a stable connection structure. On the contrary, the connecting portion 32 is provided with the clamping block 25, and by embedding the clamping block 25 into the clamping groove 323 on the valve core 20, a stable connection is also achieved. Through this clamping method, the connecting portion 32 can easily drive the valve core 20 to rotate relative to the valve body 12. During operation, the user can rotate the connecting part 32 by driving the control part 33 to rotate the valve core 20 in the valve body 10, thereby controlling the on / off state of the liquid inlet 12A and the liquid outlet 12B. This design structure is relatively simple, easy to process, and improves the accuracy and reliability of the operation. Of course, the connecting part 32 and the valve core 20 can also be fixed in a detachable manner such as threaded fitting.

[0079] Furthermore, the number of the clamping blocks 25 is at least two, and the number of the clamping grooves 323 is correspondingly at least two, and the two clamping blocks 25 are symmetrically arranged on opposite sides of the valve core 20, and the two clamping grooves 323 are symmetrically arranged on opposite sides of the connecting portion 32. This multi-point clamping design makes the connection between the connecting portion 32 and the valve core 20 more secure. The two clamping blocks 25 are symmetrically arranged on opposite sides of the valve core 20, and the two clamping grooves 323 are symmetrically arranged on opposite sides of the connecting portion 32. This symmetrical layout not only enhances the balance of the structure, but also enables the clamping blocks 25 to be evenly distributed on the valve core 20, thereby more evenly bearing and transmitting torque.

[0080] In order to further optimize the connection process between the connecting portion 32 and the valve core 20, the clamping block 25 optionally has a guide surface 251, which is used to abut against the bottom surface of the clamping groove 323 in the insertion direction of the connecting portion 32 to guide the connecting portion 32. Specifically, when the connecting portion 32 begins to be inserted into the valve core 20, the guide surface 251 on the clamping block 25 will first contact the bottom surface of the groove of the clamping groove 323. As the connecting portion 32 is further inserted, the guide surface 251 will slide along the shape of the bottom surface of the groove, guiding the clamping block 25 to gradually enter the correct position of the clamping groove 323. This design can ensure that the clamping block 25 can be accurately inserted into the clamping groove 323, avoiding the problem of installation difficulties or damage to parts caused by position deviation. In addition, the design of the guide surface 251 can also reduce the friction resistance between the connecting portion 32 and the valve core 20, making the insertion process smoother. This not only improves the convenience of operation, but also reduces the risk of damage to parts caused by improper operation.

[0081] See also Figures 3 to 5In some structural forms, the valve core 20 has a first limit portion 24, and the valve body 12 has a second limit portion 122. The first limit portion 24 has a first stop state and a second stop state abutting against the second limit portion 122. When the first limit portion 24 and the second limit portion 122 are in the first stop state, the liquid inlet 12A is connected to the liquid outlet 12B. When the first limit portion 24 and the second limit portion 122 are in the second stop state, the liquid inlet 12A is separated from the liquid outlet 12B. In this way, when the connecting portion 32 drives the valve core 20 to rotate, the interaction between the first limit portion 24 and the second limit portion 122 enables the user to clearly perceive the rotation state of the valve core 20. When the first limit portion 24 and the second limit portion 122 are in a specific stop state, the user can clearly perceive that the valve core 20 has been rotated into place, whether it is in the first stop state connecting the liquid inlet 12A and the liquid outlet 12B, or in the second stop state separating the liquid inlet 12A and the liquid outlet 12B. This design provides users with an intuitive and convenient operating experience. Through the precise cooperation of the first limit portion 24 and the second limit portion 122, the user can accurately judge the rotation position of the valve core 20 by hand feel without relying on additional tools or complicated operations. This not only simplifies the operating process and improves work efficiency, but also ensures the accuracy and reliability of the operation. In addition, the presence of the first limit portion 24 and the second limit portion 122 also enhances the stability and safety of the valve assembly 100. Since the first limit portion 24 and the second limit portion 122 can limit the rotation range of the valve core 20, damage or leakage caused by excessive rotation or improper operation is avoided. This makes the valve assembly 100 more reliable during long-term use.

[0082] Further, the first limiting portion 24 and the second limiting portion 122 are respectively a convex block 241 and a groove 1221 which cooperate with each other. The convex block 241 is inserted into the groove 1221. When the valve core 20 rotates relative to the valve body 10, the convex block 241 can slide smoothly along the inside of the groove 1221, thereby ensuring the smoothness of the rotation. Among them, the groove 1221 has a first groove wall and a second groove wall which are arranged relatively along the rotation direction of the valve core 20. When the convex block 241 abuts against the first groove wall, the convex block 241 is in a first stop state, at which time the liquid inlet 12A and the liquid outlet 12B are connected to each other, so that the laundry treatment agent can pass smoothly. When the convex block 241 abuts against the second groove wall, the convex block 241 is in a second stop state, and the liquid inlet 12A and the liquid outlet 12B are completely separated. The structural design of the convex block 241 and the groove 1221 is relatively simple, which improves the control accuracy of the valve assembly 100 and also enhances its stability and reliability. The user can sense the rotation state of the valve core 20 through the sliding of the protrusion 241 in the groove 1221, so as to more intuitively understand the current on-off state of the liquid inlet 12A and the liquid outlet 12B. In addition, this design also enables the valve assembly 100 to maintain good performance during long-term use, reducing the risk of failure caused by improper operation or wear.

[0083] Furthermore, in order to improve the stability and controllability of the valve assembly 100, at least two protrusions 241 are provided, and the two protrusions 241 are symmetrically arranged relative to the central axis of the valve core 20, and at least two grooves 1221 are correspondingly provided, and one protrusion 241 matches one groove 1221. As the number of protrusions 241 increases and they are symmetrically arranged, the valve core 20 is more stable during the rotation process, and the shaking and vibration are reduced, thereby improving the reliability and service life of the valve assembly 100.

[0084] Reference Figure 2 , Figure 4 as well as Figure 5In some structural forms, the liquid inlet 12A and the liquid outlet 12B are both provided on the side wall of the valve cavity 121, and the side wall of the liquid adding cavity 21 is provided with two liquid holes 211 connected to the liquid adding cavity 21. Specifically, when the two liquid holes 211 are respectively connected to the liquid inlet 12A and the liquid outlet 12B, the clothing treatment agent can smoothly flow into the liquid adding cavity 21 from the liquid inlet 12A, and then flow out to the liquid outlet 12B through the other liquid hole 211. At this time, the liquid inlet 12A and the liquid outlet 12B are connected, and the clothing treatment agent can flow freely. When the liquid inlet 12A or the liquid outlet 12B is not in a correspondingly connected position with the liquid holes 211, the flow channel of the clothing treatment agent is cut off, and a partition state is formed between the liquid inlet 12A and the liquid outlet 12B, and the clothing treatment agent cannot flow. The design of the liquid hole 211 not only simplifies the structure of valve opening and closing, but also improves the flexibility of valve operation. This is achieved by adjusting the corresponding relationship between the liquid hole 211 and the liquid inlet 12A and the liquid outlet 12B, thus providing users with a more convenient and reliable infusion control solution.

[0085] It should be noted that when the liquid inlet 12A and the liquid outlet 12B are separated, only the liquid inlet 12A may be disconnected from the liquid passage hole 211 or only the liquid outlet 12B may be disconnected from the liquid passage hole 211. Of course, both the liquid inlet 12A and the liquid outlet 12B may be disconnected from the liquid passage hole 211 at the same time.

[0086] In the embodiment where only the liquid inlet 12A or the liquid outlet 12B is not connected to the liquid passage hole 211, there are the following two situations: Situation A, only the liquid inlet 12A is not connected to the liquid passage hole 211. In this case, when the valve core 20 rotates or moves to a certain position, the liquid passage hole 211 originally corresponding to the liquid inlet 12A will be misplaced, resulting in the liquid inlet 12A and the liquid passage hole 211 no longer being connected. At this time, although the liquid outlet 12B is still connected to the other liquid passage hole 211, since the liquid inlet 12A has been disconnected, the clothing treatment agent cannot flow from the liquid inlet 12A into the liquid adding chamber 21, and thus cannot flow out from the liquid outlet 12B. In this state, a partition is formed between the liquid inlet 12A and the liquid outlet 12B, achieving complete control over the flow of the clothing treatment agent. Case B: Only the liquid outlet 12B is not connected to the liquid passage hole 211. Similarly, when the valve core 20 rotates or moves to another specific position, the liquid passage hole 211 originally corresponding to the liquid outlet 12B will be misplaced, resulting in the liquid outlet 12B no longer being connected to the liquid passage hole 211. At this time, although the liquid inlet 12A is still connected to the other liquid passage hole 211, since the liquid outlet 12B has been disconnected, the laundry treatment agent can enter the liquid filling chamber 21, but cannot flow out from the liquid outlet 12B. In this state, although the laundry treatment agent can flow inside the liquid filling chamber 21 of the valve core 20, it cannot be discharged through the liquid outlet 12B, which also achieves complete control of the flow of the laundry treatment agent.

[0087] In the embodiment where the liquid inlet 12A and the liquid outlet 12B are not connected to the liquid hole 211 at the same time, when the valve core 20 rotates to a specific closed position, the two liquid holes 211 will be misaligned with the liquid inlet 12A and the liquid outlet 12B at the same time, resulting in the liquid inlet 12A and the liquid outlet 12B not being connected to the liquid hole 211. At this time, both the liquid inlet 12A and the liquid outlet 12B are completely isolated from the liquid adding chamber 21, and the clothes treating agent cannot enter or flow out of the valve body 12. In this state, a complete isolation state is formed between the liquid inlet 12A and the liquid outlet 12B, ensuring the absolute stillness and sealing of the clothes treating agent.

[0088] Reference Figure 2 , Figure 4 as well as Figure 5 Optionally, the valve assembly 100 further includes two first seals 40, both of which are arranged between the outer side wall of the valve core 20 and the cavity side wall of the valve cavity 121. Among them, the arrangement of the first seal 40 effectively isolates the valve core 20 from direct contact with the cavity side wall of the valve body 12, avoiding wear caused by friction, thereby significantly extending the service life of the valve core 20 and the valve body 12. Moreover, this design also reduces the noise generated by friction and improves the user experience. In terms of installation, the first seal 40 can be directly fixed on the outer side wall of the valve core 20, so that when the valve core 20 is installed, the installation of the first seal 40 can be realized simultaneously, which greatly simplifies the installation process. Of course, the first seal 40 can also be directly connected to the cavity side wall of the valve body 12. No matter which installation method is used, it can ensure the close fit between the first seal 40 and the valve core 20 and the valve body 12 to achieve a sealing effect.

[0089] In one structural form, two first sealing members 40 and two liquid holes 211 are alternately arranged along the circumference of the valve core 20. When the liquid inlet 12A and the liquid outlet 12B are separated, the two first sealing members 40 are respectively arranged around the circumference of the liquid inlet 12A and the liquid outlet 12B to form a seamless sealing barrier. Such a design ensures that when the liquid inlet 12A and the liquid outlet 12B remain in a closed state, even if the laundry treatment agent is in a high pressure state, it can effectively prevent the laundry treatment agent from leaking from the circumference of the liquid inlet 12A and the circumference of the liquid outlet 12B into the cavity side wall of the valve body 12, thereby avoiding the waste and pollution of the laundry treatment agent.

[0090] In another structural form, two first sealing members 40 are respectively arranged around two liquid holes 211. When the liquid inlet 12A and the liquid outlet 12B are connected, the two first sealing members 40 are respectively arranged around the peripheral sides of the liquid inlet 12A and the liquid outlet 12B. That is, such a design ensures that when the liquid inlet 12A and the liquid outlet 12B remain connected, even if the laundry treatment agent is in a high pressure state, it can effectively prevent the laundry treatment agent from leaking from the peripheral sides of the liquid inlet 12A and the liquid outlet 12B into the cavity side wall of the valve body 12, thereby avoiding the waste and pollution of the laundry treatment agent.

[0091] Optionally, the valve assembly 100 further includes a second seal 50, which is disposed between the outer side wall of the valve core 20 and the side wall of the valve cavity 121. Similarly, the second seal 50 can also avoid direct contact between the valve core 20 and the valve body 12. The second seal 50 is disposed circumferentially along the outer side wall of the valve core 20 and is located on the side of the liquid hole 211 close to the top wall 22 of the valve core 20. Such a layout enables the second seal 50 to effectively seal the small gap between the valve core 20 and the side wall of the valve body 12, thereby preventing the laundry treatment agent from leaking from a position close to the top wall 22 of the valve core 20 under high pressure or high speed flow conditions. This design not only improves the sealing performance of the valve assembly 100, but also further enhances the safety and reliability of the entire system.

[0092] Optionally, the valve assembly 100 further includes a third sealing member 60, which is disposed between the outer side wall of the valve core 20 and the cavity side wall of the valve cavity 121, and the third sealing member 60 is disposed circumferentially along the outer side wall of the valve core 20, and is located on the side of the liquid passage hole 211 close to the bottom wall 23 of the valve core 20. Such a layout enables the third sealing member 60 to effectively seal the small gap between the valve core 20 and the cavity side wall of the valve body 12, thereby preventing the laundry treatment agent from leaking from a position close to the bottom wall 23 of the valve core 20 under high pressure or high speed flow conditions, so as to further improve the sealing performance of the valve assembly 100.

[0093] Of course, in order to further improve the sealing performance of the valve assembly 100, in some embodiments, a second sealing member 50 and a third sealing member 60 are provided at the same time. The second sealing member 50, as described above, is located on the side of the liquid hole 211 close to the top wall 22 of the valve core 20, while the third sealing member 60 is located on the side of the top wall 22 of the valve core 20. This double sealing structure further enhances the sealing effect of the valve assembly 100.

[0094] Reference Figure 2 , Figure 4 as well as Figure 5In some structural forms, the bottom wall 23 of the valve cavity 121 is provided with a liquid passage port 12C, the top wall 22 of the valve core 20 is provided with a first opening 221 connected to the liquid adding cavity 21, and the bottom wall 23 of the valve core 20 is provided with a second opening 231 connected to the liquid adding cavity 21, and the second opening 231 is connected to the liquid passage port 12C. The operating member 30 includes a first baffle 321 and a second baffle 322 connected to the side wall of the connecting portion 32. The connecting portion 32 and the first baffle 321 and the second baffle 322 may be an integral structure to ensure the stability of the overall structure of the operating member 30. In this way, when the two liquid passage holes 211 are respectively connected to the liquid inlet 12A and the liquid outlet 12B, the first baffle 321 abuts against the top wall 22 of the valve core 20 to block the first opening 221, and the second baffle 322 abuts against the bottom wall 23 of the valve core 20 to block the second opening 231. The first baffle 321 and the second baffle 322 effectively block the first opening 221 and the second opening 231, ensuring that during the process of the laundry treatment agent being transferred from the liquid inlet 12A to the liquid outlet 12B, the laundry treatment agent can only pass through the liquid filling chamber 21 through the preset liquid passage hole 211, thereby reducing the possibility of the laundry treatment agent leaking from the first opening 221 and the second opening 231. At the same time, blocking the second opening 231 also prevents the laundry treatment agent from accidentally flowing out from the liquid passage port 12C when the liquid inlet 12A and the liquid outlet 12B are connected.

[0095] When the liquid inlet 12A and the liquid outlet 12B are cut off, the connecting portion 32 can be directly disassembled and separated from the valve core 20, or the sealing portion 31 can be disassembled from the valve housing 11 to drive the connecting portion 32 to move, so that the connecting portion 32 can be separated from the valve core 20. Thus, the first baffle 321 no longer blocks the first opening 221, and the second baffle 322 no longer blocks the second opening 231. In this way, after the sealing portion 31 opens the liquid adding port 10a, the laundry treatment agent can naturally flow into the liquid adding chamber 21 through the first opening 221 under the action of gravity, and then smoothly enter the liquid adding port 10a through the second opening 231, thereby completing the liquid adding process.

[0096] Furthermore, the valve assembly 100 further includes a fourth sealing member 70, which is disposed between the top wall 22 of the valve core 20 and the first baffle 321, and is disposed along the circumference of the first opening 221. Thus, when the first baffle 321 abuts against the top wall 22 of the valve core 20 to block the first opening 221, the fourth sealing member 70 can fit tightly to form an effective sealing barrier, further preventing the laundry treatment agent in the liquid adding chamber 21 from leaking through the first opening 221.

[0097] Optionally, the valve assembly 100 further includes a fifth sealing member 80, which is disposed between the bottom wall 23 of the valve core 20 and the second baffle plate 322 and is disposed along the circumference of the second opening 231. When the second baffle plate 322 abuts against the bottom wall 23 of the valve core 20 to block the second opening 231, the fifth sealing member 80 will be tightly fitted to provide additional sealing protection for the second opening 231, further preventing the laundry treatment agent in the liquid adding chamber 21 from leaking through the second opening 231.

[0098] It should be noted that the first seal 40, the second seal 50, the third seal 60, the fourth seal 70 and the fifth seal 80 can be made of high-quality elastic materials such as silicone and rubber. These materials not only have good elasticity and sealing performance, but also can adapt to various temperature and humidity environments, ensuring that the valve assembly 100 can work stably under various conditions.

[0099] Reference Figure 6 The liquid adding channel 10A in another embodiment of the present application is different from the liquid adding channel 10A in the above embodiment. Specifically, the valve body 10 includes a valve shell 11 and a valve body 12. The valve shell 11 has a mounting cavity 111 and a liquid adding port 10a connected to the mounting cavity 111. The valve body 12 has a valve cavity 121. The valve core 20 is movably arranged in the valve cavity 121. The liquid inlet 12A and the liquid outlet 12B are arranged on the side wall of the valve cavity 121. The operating member 30 also includes a connecting portion 32 connected to the sealing portion 31. The connecting portion 32 is connected to the valve core 20. The operating member 30 has a rotation axis passing through the connecting portion 32 and the sealing portion 31. The first movement is a movement in which the connecting portion 32 rotates around the rotation axis and drives the valve core 20 to rotate relative to the valve body 10. The valve body 12 is at least disposed in the installation cavity 111 . The installation cavity 111 and the valve cavity 121 are connected to form a liquid adding passage 10A. The bottom wall 23 of the valve cavity 121 is provided with a liquid port 12C connected to the liquid adding passage 10A.

[0100] In this way, when the liquid filling port 10a is opened, when the user adds clothing treatment agent through the liquid filling port 10a, the clothing treatment agent can flow from the installation cavity 111 and the valve cavity 121 to the liquid filling port 12C in sequence, thereby completing the liquid filling process. And the cover part 31 is a cover body that can be flipped relative to the connecting part 32, and the second movement is the flipping movement of the cover body relative to the connecting part 32. Alternatively, in another structural form, the cover part 31 is a cover body that can be moved relative to the connecting part 32, and the second movement is the translational movement of the cover body relative to the connecting part 32. That is, the cover part 31 can be used as a flippable cover body to open or cover the liquid filling port 10a through a flipping movement relative to the connecting part 32, or as a movable cover body, which is slidably connected to the connecting part 32 through the setting of the slide rail and the slider, so as to perform a translational movement to cover or open the liquid filling port 10a. This design not only simplifies the operation process, but also improves the convenience and stability of the operation. Whether it is flipping or translation, the operation of the capping part 31 does not need to move the connecting part 32, which makes the liquid adding process more concise and efficient. In addition, this design also enhances the flexibility and maintainability of the system, bringing users a better use experience.

[0101] Reference Figure 7 The liquid adding channel 10A in another embodiment of the present application is different from the liquid adding channel 10A in the above embodiment. The valve body 10 includes a valve shell 11 and a valve body 12. The valve shell 11 has a mounting cavity 111 and a liquid adding port 10a connected to the mounting cavity 111; the valve body 12 has a valve cavity 121 and a liquid inlet 12A and a liquid outlet 12B connected to the valve cavity 121. The valve body 12 is at least partially disposed in the mounting cavity 111, and the valve core 20 is movably disposed in the valve cavity 121. The operating member 30 also includes a connecting portion 32 connected to the sealing portion 31, and the connecting portion 32 is connected to the valve core 20. The operating member 30 has a rotation axis passing through the connecting portion 32 and the sealing portion 31. The first movement is a movement in which the connecting portion 32 rotates around the rotation axis and drives the valve core 20 to rotate relative to the valve body 10. The valve core 20 has a liquid adding cavity 21, and the valve core 20 includes a liquid passing conduit 26 disposed in the liquid adding cavity 21 and used to connect the liquid inlet 12A and the liquid outlet 12B, and the liquid passing conduit 26 is isolated from the liquid adding cavity 21. In this way, the valve core 20 is driven to rotate relative to the valve body 10 through the connecting portion 32, so as to synchronously drive the liquid passing conduit 26 to connect and disconnect with the liquid inlet 12A and the liquid outlet 12B.

[0102] The bottom wall 23 of the valve cavity 121 is provided with a liquid passage port 12C, the top wall 22 of the valve core 20 is provided with a first opening 221 connected to the liquid adding cavity 21, the bottom wall 23 of the valve core 20 is provided with a second opening 231 connected to the liquid adding cavity 21, the second opening 231 is connected to the liquid passage port 12C, the installation cavity 111, the first opening 221, the liquid adding cavity 21, the second opening 231, and the liquid passage port 12C are connected in sequence to form a liquid adding channel 10A. In this way, the liquid passage pipe 26 and the liquid adding channel 10A are separated so that the liquid adding process and the liquid passing process can be carried out simultaneously without affecting each other. When the liquid adding port 10a is opened, when the user adds clothing treatment agent through the liquid adding port 10a, the clothing care agent can flow from the installation cavity 111, the first opening 221, the liquid adding cavity 21, the second opening 231, to the liquid passage port 12C in sequence, thereby completing the liquid adding process. At the same time, since the liquid passage pipe 26 is isolated from the liquid adding chamber 21 , the liquid adding process will not affect the flow of liquid in the liquid passage pipe 26 .

[0103] And the capping part 31 is a cover body that can be flipped relative to the connecting part 32, and the second movement is the flipping movement of the cover body relative to the connecting part 32. Or, in another structural form, the capping part 31 is a cover body that can be moved relative to the connecting part 32, and the second movement is the translational movement of the cover body relative to the connecting part 32. That is, the capping part 31 can be used as a flippable cover body to open or cover the liquid filling port 10a by flipping the cover body relative to the connecting part 32, or it can be used as a movable cover body to achieve sliding connection with the connecting part 32 through the setting of the slide rail and the slider, so as to perform translational movement to cover or open the liquid filling port 10a. This design not only simplifies the operation process, but also improves the convenience and stability of the operation. Whether it is flipping or translation, the operation of the capping part 31 does not need to move the connecting part 32, which makes the liquid filling process more concise and efficient. In addition, this design also enhances the flexibility and maintainability of the system, bringing users a better quality experience.

[0104] The above is an explanation of the valve assembly 100 proposed in the embodiment of the present application. Since the clothing processing device 1000 proposed in the embodiment of the present application adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0105] Reference Figure 1 , Figure 2 as well as Figure 8Furthermore, the clothing treatment device 1000 also includes a liquid storage box 200, a liquid inlet pipe 300, a clothing treatment barrel 400 and a liquid outlet pipe 500, forming a complete clothing treatment system. First, the liquid storage box 200 is directly connected to the liquid adding channel 10A, which allows the user to easily add clothing treatment agent to the liquid storage box 200. The liquid inlet pipe 300 acts as a bridge, connecting the liquid storage box 200 with the liquid inlet 12A of the valve assembly 100, ensuring that the clothing treatment agent can flow smoothly to the next link. A clothing treatment chamber 401 is provided in the clothing treatment barrel 400, which is the core area of ​​clothing treatment. The liquid outlet pipe 500 connects the liquid outlet 12B of the valve assembly 100 with the clothing treatment chamber 401, forming a delivery channel for the clothing treatment agent.

[0106] When the liquid inlet 12A of the valve assembly 100 is connected to the liquid outlet 12B, the laundry treatment agent in the liquid storage box 200 can flow into the laundry treatment chamber 401 in a variety of ways. On the one hand, it can flow naturally under the action of gravity, pass through the liquid inlet pipe 300, the valve assembly 100 and the liquid outlet pipe 500 in sequence, and finally reach the laundry treatment chamber 401 to treat the clothes. On the other hand, the laundry treatment device 1000 can also be equipped with a pump body, which can be set at the liquid inlet pipe 300 or the liquid outlet pipe 500, and the power provided by the pump body drives the laundry treatment agent to flow into the laundry treatment chamber 401 more efficiently.

[0107] When it is necessary to add clothes treating agent to the liquid storage box 200, the user only needs to remove the operating member 30 from the valve body 10 or the valve core 20 to open the liquid adding port 12C. At this time, the user can directly add clothes treating agent into the liquid storage box 200 from the liquid adding channel, ensuring that the system can continuously provide clothes treating agent to meet the needs of treating clothes for a long time or a large amount of clothes.
