It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0054] Combine Figures 1 to 14 As shown, according to a specific embodiment of the present application, a washing machine is provided.

[0055] Specifically, the washing machine includes: a body assembly and a rotating shaft mechanism, the body assembly includes a first body 2 and a second body 3, the top of the first body 2 and the second body 3 are both provided with an installation cavity, and each installation cavity is correspondingly provided with a washing tub assembly 1, wherein each washing tub assembly 1 is detachably installed in the installation cavity through a lower shell 11; the first body 2 and the second body 3 are movably connected by a rotating shaft mechanism, so that one of the first body 2 and the second body 3 can be rotated relative to the other to an expanded position and a storage position, wherein, when the first body 2 and the second body 3 are in the expanded position, each washing tub assembly 1 can be detachably placed on the first body 2 and the second body 3, and when the first body 2 and the second body 3 are in the storage position, the first body 2 and the second body 3 are in an overlapping state.

[0056] The technical solution of the present invention utilizes a dual-body and dual-tub assembly structure, combined with an ingenious rotating shaft mechanism, to achieve efficient folding and multifunctional use of the washing machine. The rotating shaft mechanism connects the first body 2 and the second body 3, allowing one of the first body 2 and the second body 3 to rotate relative to the other between an unfolded position and a stowed position. This design significantly reduces the space occupied by the washing machine during storage. This application solves the problem of conventional twin-tub washing machines being inconvenient to use and difficult to store in limited space.

[0057] In this embodiment, the detachable washing tub assembly cooperates with the mounting cavity at the top of the washing machine, achieving a modular design. Users can replace or clean the washing tub assembly as needed, improving the flexibility and hygiene of the washing machine. To wash clothes, the user deploys the first and second bodies to the deployed position using the hinge mechanism, then installs the washing tub assembly and begins washing. After washing is complete, the washing tub assembly is disassembled, and the first and second bodies are rotated to their stowed positions using the hinge mechanism, achieving efficient space utilization.

[0058] like Figure 1 As shown, at least two washing tub assemblies 1 are provided, and each washing tub assembly 1 is provided independently. Each washing tub assembly 1 is provided with an upper cover 10, a tub body, a button 12 and a handle 13. The button 12 is provided on the upper cover 10. By pressing the button 12, the upper cover can be opened to take and put clothes. The handle 13 is connected to the tub body. The design of the handle 13 allows the user to easily lift or move the washing tub assembly 1. In particular, when the washing tub assembly needs to be removed from the body assembly for cleaning, maintenance or moving to another location, the handle provides a necessary gripping point, making the operation more convenient.

[0059] Specifically, the shaft mechanism includes a first shaft 21, a second shaft 31, and a shaft housing 4. The first shaft 21 and the second shaft 31 extend along the width of the washing machine assembly and are arranged parallel to each other. At least one of the first shaft 21 and the second shaft 31 is rotatably connected to the shaft housing 4. The first shaft 21 and the second shaft 31 are respectively connected to the first and second bodies 2 and 3. The first and second bodies 2 and 3 can be switched between an extended position and a stowed position by rotating the first and second shafts 21 and 31. In the extended position, the two bodies are arranged in parallel, providing a stable base for the washing tub assembly 1 to perform washing operations. In the overlapped position, the two bodies are stacked together by the relative rotation of the first and second shafts 21 and 31, significantly reducing the overall size of the washing machine and facilitating storage and transportation.

[0060] Specifically, if Figure 2 、 Figure 3 As shown, the first body 2 and the second body 3 have a accommodating cavity, and at least one motor 7 is provided in the first body 2 and the second body 3: the motor 7 is located in the accommodating cavity, and the output shaft of the motor 7 is connected to the impeller 8 provided at the bottom of the washing tub assembly 1; the first rotating shaft 21 and the second rotating shaft 31 are respectively provided in the accommodating cavity, or the first rotating shaft 21 and the second rotating shaft 31 at least partially protrude from the accommodating cavity.

[0061] Motor 7 acts as a power source, driving the impeller 8 inside the washing machine to rotate, generating water flow and thus washing the clothes. The output shaft of motor 7 is connected to impeller 8, located at the bottom of the washing tub assembly 1, via a coupling or other transmission device. When the motor is running, the torque generated by its output shaft is transmitted to impeller 8, causing it to rotate at a set speed and direction. The blades on impeller 8 stir the water in the tub, generating vortices, causing the clothes to tumble and rub in the water, completing the washing process. The rotation speed and direction of impeller 8 are determined by motor 7, thereby adapting to different washing modes, such as gentle washing and strong washing.

[0062] The first rotating shaft 21 and the second rotating shaft 31 are key components for achieving the folding of the washing machine. They allow relative rotation between the first body 2 and the second body 3, thereby completing the folding operation. In this embodiment, the first rotating shaft 21 and the second rotating shaft 31 can be completely located within their respective accommodating cavities, or they can partially protrude outside the accommodating cavities (i.e., they can be designed as internal dual rotating shafts or external dual rotating shafts). The external dual rotating shaft design means that the first rotating shaft 21 and the second rotating shaft 31 are designed to be embedded inside the washing machine main body and are not exposed to the outside. Through the rotation of the internal rotating shafts, the first and second main bodies of the washing machine can be folded along a designed path, such as folding upward or folding to the sides, without seeing the exposed rotating shafts, maintaining the beauty and neatness of the machine. The external dual rotating shaft design means that the first rotating shaft 21 and the second rotating shaft 31 are at least partially located outside the body and are directly visible. This is usually to simplify mechanical design and reduce costs while providing an intuitive folding operation experience.

[0063] In this embodiment, at least one of the first rotating shaft 21 and the second rotating shaft 31 can be protruded along the length direction or width direction of the corresponding body component, at least partially located outside the accommodating cavity, and not completely wrapped by the outer shell of the body component. The protruding design of the rotating shaft allows the washing machine body to rotate in a more natural and smoother manner when folded, without being restricted by the internal space of the accommodating cavity, and the rotation process is more intuitive. This design optimizes the folding path, making the washing machine more flexible when unfolding and storing, and reducing friction and mechanical stress during the folding process. Since the rotating shaft is not completely located in the accommodating cavity, the space inside the body can be planned more effectively and freely, providing more installation space for other core components (such as motors). The rotating shaft is partially located outside the accommodating cavity, which helps to dissipate heat from the motor and other heat-generating components. When the washing machine is working, the heat inside the body can be dissipated through the contact surface between the rotating shaft and the outside world, thereby reducing the internal temperature, extending the life of electronic components, and improving the overall performance of the washing machine.

[0064] like Figures 4 to 8 As shown, a process of rotating the first body 2 and the second body 3 from the deployed position so that the first body 2 and the second body 3 are in the stored position is shown, for example: the first body 2 is rotated relative to the second body 3 by a first preset angle (the first preset angle is 90°), and then continued to rotate by a second preset angle (the second preset angle is 90°); or the second body 3 is rotated relative to the first body 2 by the first preset angle and the second preset angle in sequence, or the first body 2 and the second body 3 are simultaneously rotated in opposite directions by the first preset angle.

[0065] Specifically, a first curved surface 22 is provided on the side of the first body 2 proximate to the second body 3, and a second curved surface 32 is provided on the side of the second body 3 proximate to the first body 2. The first curved surface 22 and the second curved surface 32 are arranged opposite each other along the length of the body assembly. When the two bodies rotate relative to each other via the hinge mechanism, that is, when the first body 2 and the second body 3 transition from an unfolded state to a folded state (or vice versa), the presence of the curved surfaces significantly reduces the contact area between the bodies, thereby lowering frictional resistance and ensuring a smoother and more labor-saving folding process. The curved design also prevents jamming or damage that may occur when hard edges are joined.

[0066] Specifically, if Figure 9 As shown, the hinge mechanism includes a first hinge 21, a second hinge 31, a third hinge 25, a fourth hinge 35, and a hinge housing 4. The first hinge 21 and the third hinge 25 are spaced apart along the width direction of the first housing 2, and are coaxially arranged with each other. The first hinge 21 and the third hinge 25 are rotatably arranged relative to the first housing 2. The second hinge 31 and the fourth hinge 35 are spaced apart along the width direction of the second housing 3, and are coaxially arranged with each other. The second hinge 31 and the fourth hinge 35 are rotatably arranged relative to the second housing 3. The first hinge 21 and the third hinge 25 are connected to a first side of the hinge housing 4, and the second hinge 31 and the fourth hinge 35 are connected to a second side of the hinge housing 4, with the first side being arranged opposite the second side. The multi-axis design principle of the hinge mechanism is to improve the stability and flexibility of the folding and unfolding of the housing by increasing the number of hinges. The implementation effect is to make the body components more compact when folded and more stable when unfolded.

[0067] The first and third rotating shafts 21 and 25 are spaced apart along the width of the first housing 2 and are coaxial, meaning they share a common centerline and can rotate synchronously. Similarly, the second and fourth rotating shafts 31 and 35 are spaced apart along the width of the second housing 3 and are also coaxial and rotatable relative to the second housing 3. In this embodiment, the first and third rotating shafts 21 and 25 are connected by a linkage on the first side of the housing 4, enabling them to rotate freely about their common centerline. Similarly, the second and fourth rotating shafts 31 and 35 are similarly connected on the second side. This design ensures that when a user operates any one rotating shaft, the other rotating shaft on the same side also rotates in tandem, driving the rotation of the first or second housing 2 or 3. To convert the washing machine from an unfolded state to a folded state, the user can operate the first or third rotating shaft 21 or 25 to rotate them by a first predetermined angle (90°). As the first and third rotating shafts rotate, the first housing 2 begins to fold. Then drive the first rotating shaft 21 or the third rotating shaft 25 to drive them to rotate a second preset angle (90°). Under the guidance of the rotating shaft, the first body 2 and the second body 3 can be smoothly overlapped to form a compact structure, which greatly saves storage space.

[0068] Specifically, a locking portion is provided on the bottom of at least one of the first and second housings 2, 3. When the first and second housings 2, 3 are in the stowed position, the locking portion locks the first and second housings 2, 3 together. The locking portion is provided to stably lock the first and second housings 2, 3 in the stowed state, preventing the washing machine from accidentally unfolding during storage and ensuring stability during storage or transport.

[0069] Specifically, the locking portion includes a first latching structure and a second latching structure, one of which is located at the bottom of the first body 2, and the other of which is located at the bottom of the second body 3. When the washing machine is folded and stored, the first and second latching structures engage with each other, forming a mechanical lock that prevents accidental separation during transport or storage. This ensures the structural integrity of the washing machine and reduces the risk of damage caused by instability. When the washing machine needs to be unfolded for use, the lock between the first and second latching structures is released, allowing the user to easily open and position the washing machine and begin washing.

[0070] The specific implementation of the snap-fit structure can be achieved in a variety of ways, but common ones include: The first snap-fit structure can be a buckle with an elastic locking tongue, typically supported by a spring or elastic material. When the body is folded into place, the locking tongue automatically pops out and snaps into a slot or hole in the second snap-fit structure, achieving locking. The second snap-fit structure corresponds to the first snap-fit structure and can be a socket with a slot or hole. The shape of the slot or hole matches the locking tongue of the first snap-fit structure, ensuring precise docking and a secure connection.

[0071] Specifically, if Figure 10 、 Figure 11 As shown, there are multiple first clip structures, at least one of which includes a first locking hole 24, and the remaining multiple first clip structures include at least one first locking protrusion 23. There are multiple second clip structures, at least one of which includes a second locking hole 34 that cooperates with the first locking protrusion 23, and the remaining multiple second clip structures include at least one second locking protrusion 33 that cooperates with the first locking hole 24.

[0072] When the first and second bodies 2, 3 are folded together, the first locking protrusion 23 precisely aligns and engages with the second locking hole 34. Simultaneously, the second locking protrusion 33 also engages within the first locking hole 24. This engagement of the protrusion and hole creates a mechanical lock, ensuring a stable connection between the bodies in the folded state. The coordination of multiple latching structures ensures the overall stability and compactness of the twin-tub washing machine in the folded state, reducing damage caused by accidental shaking or impact during transport or storage. The flexible design and distribution of the locking holes and locking protrusions allows the washing machine to adapt to washing tubs of varying sizes and shapes, and maintain stability and safety in a variety of usage environments.

[0073] When the first body 2 and the second body 3 are in the expanded position, the first locking protrusion 23 and the second locking protrusion 33 protrude from the bottom of the first body 2 and the second body 3, and the first locking protrusion 23 and the second locking protrusion 33 directly contact the ground to avoid direct wear or collision on the bottom surface of the body assembly.

[0074] Specifically, the volumes of the tubs of each washing tub assembly 1 can be set to the same size, or the volumes of the tubs can be set to different sizes. The dual-tub volume-adjustable design principle is to provide washing tub assemblies of the same or different volumes to meet users' varying washing requirements. This improves the flexibility and efficiency of the washing machine, allowing users to select the appropriate washing tub assembly 1 for washing according to the size of the laundry load.

[0075] like Figure 12As shown, the two washing tub assemblies 1 are arranged in a large and small configuration, making them suitable for living environments with limited space, such as small apartments, student dormitories, or bachelor pads. This combination is very flexible in daily use. The large tub can be used to wash large items or large quantities of clothing, while the small tub is suitable for washing small items such as underwear and socks, or clothing made of special materials, to avoid mixing with other clothes. It is mainly aimed at young users aged 18-35, including students, young professionals, singles, and small families. This group generally pursues cost-effectiveness, practicality, and convenience, and has high requirements for hygiene and personalized washing.

[0076] like Figure 13 As shown, the two washing tub assemblies 1 are configured as two large tubs, suitable for scenarios requiring large amounts of laundry, such as before and after family gatherings, for large households, or for washing staff uniforms in small commercial spaces like hotels. This dual tub configuration allows for simultaneous processing of large quantities of different types of laundry, improving washing efficiency and saving time. Target users include families with children, extended multi-generational households, and small and medium-sized businesses with multiple employees. These groups or businesses typically face high-frequency and high-volume laundry needs, seeking efficient and high-volume washing capabilities.

[0077] like Figure 14 As shown, the two washing tub assemblies 1 are designed as two small tubs, suitable for those living in small spaces who require meticulously divided washing, such as families with children. The two tubs can be used to wash baby clothes and adult clothes, or clothes of different colors, respectively, to avoid cross-contamination and ensure effective washing and clothing hygiene. This is primarily designed for users with specific requirements for laundry hygiene, such as new parents, family members with sensitive skin, and individuals with high demands for clothing care. The two-tub combination not only saves space but also allows for meticulous washing, making it ideal for small families or individuals who prioritize clothing hygiene and care.

[0078] Specifically, when the first and second bodies 2 and 3 are in the deployed position, the output shaft of the motor 7 within the first body 2 is arranged parallel to the output shaft of the motor 7 within the second body 3. The parallel arrangement of the two motor output shafts ensures that the washing tubs on both sides rotate synchronously and maintain consistent motion trajectories during operation, which helps maintain the overall balance of the washing machine and reduces vibration and noise caused by imbalance. The parallel output shafts directly drive their respective washing tubs, avoiding energy loss during power transmission and improving the transmission efficiency of the entire system. Furthermore, the parallel arrangement helps simplify the transmission mechanism, reducing the number and complexity of transmission components, thereby reducing production costs and maintenance difficulties.

[0079] Specifically, when the first body 2 and the second body 3 are in the storage position, one of the first body 2 and the second body 3 is positioned below the other. When the first body 2 and the second body 3 are in the storage position, the second body 3 (or the first body 2, depending on the specific design) can be folded and placed below the first body 2 (or the second body 3) by rotating the hinge mechanism. For example, operating the first hinge 21 to rotate the first body 2 90° along the vertical axis relative to the second body 3 allows the first body 2 to be laterally aligned with the second body 3. Subsequently, at least one of the first hinge 21 and the second hinge 31 is rotated 90° until one of the bodies is completely positioned below the other, and the two bodies are tightly stacked together to form a compact structure. At this point, the first and second latching structures, through the engagement of the locking holes and the locking protrusions, ensure that the bodies are tightly locked in the storage position, preventing accidental unfolding or shaking.

[0080] Specifically, when the first and second bodies 2, 3 are in the stowed position, the output shaft of the motor 7 within the first body 2 is coaxial with the output shaft of the motor 7 within the second body 3. The internal structure of the body assembly requires full consideration of the motor's installation position and the orientation of its output shafts. When the first and second bodies 2, 3 are in the stowed position, the motor output shafts can be precisely aligned, achieving coaxiality. This coaxial stowage of the motor output shafts minimizes the overall size of the washing machine, particularly in height, making it easy to store even in confined spaces.

[0081] It should be further explained that knobs 6 are provided on the exterior surfaces of both the first and second housings 2, 3. Each knob 6 independently controls the corresponding washing tub assembly 1. Knobs 6 allow the user to independently select the wash cycle for each washing tub assembly. For example, the user can select a gentle wash mode on one side and an intense clean mode on the other, meeting the washing needs of different clothing types.

[0082] Specifically, a plurality of support members 200 are provided on the top of each of the first and second housings 2, 3. Each support member 200 is arranged along the circumference of the first and second housings 2, 3, and at least partially protrudes from the upper surface of the first and second housings 2, 3.
