Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a washing machine. Background Technology

[0002] Currently, with the acceleration of urbanization and the diversification of living conditions, especially the widespread adoption of small apartments, efficient space utilization has become a crucial consideration in modern home design. Against this backdrop, the size and space occupied by washing machines, as an indispensable household appliance, have become a focus of consumer attention. While traditional twin-tub washing machines offer convenience in separating laundry, their fixed structure and large footprint pose significant inconvenience and storage challenges for living environments with limited space.

[0003] For target consumers such as renters, students, young professionals, and new parents, who often live in spaces with limited room availability, such as dormitories and small apartments, the size and portability of a washing machine become important factors when making a purchase decision. However, most twin-tub washing machines on the market are not designed with the actual needs of these users in mind. They are usually large and heavy, making it difficult to find a suitable place in a small space and extremely inconvenient to move and store.

[0004] No effective solutions have yet been proposed for the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a washing machine to solve the problems of inconvenience in using and storage of twin-tub washing machines in limited space in the prior art.

[0011] Furthermore, at least one of the first and second bodies has a locking part at its bottom, and when the first and second bodies are in the storage position, the first and second bodies are locked together by the locking part.

[0012] Furthermore, the locking part includes a first locking structure and a second locking structure, wherein one of the first locking structure and the second locking structure is disposed at the bottom of the first body, and the other of the first locking structure and the second locking structure is disposed at the bottom of the second body.

[0013] Furthermore, there are multiple first snap-fit ​​structures, at least one of which includes a first locking hole, and the remaining multiple first snap-fit ​​structures include at least one first locking protrusion.

[0014] Furthermore, there are multiple second locking structures, at least one of which includes a second locking hole that mates with the first locking protrusion, and the remaining multiple second locking structures include at least one second locking protrusion that mates with the first locking hole.

[0015] Furthermore, the volume of each tub in each washing tub assembly is set to be the same, or the volume of each tub is set to be different.

It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0054] Combination Figures 1 to 14 As shown, according to a specific embodiment of this 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 both the first body 2 and the second body 3 is provided with an installation cavity, and each installation cavity is provided with a washing tub assembly 1. Each washing tub assembly 1 is detachably installed in the installation cavity through a lower housing 11. The first body 2 and the second body 3 are movably connected through the rotating shaft mechanism, so that one of the first body 2 and the second body 3 can rotate relative to the other to an unfolded position and a retracted position. When the first body 2 and the second body 3 are in the unfolded position, each washing tub assembly 1 is detachably placed on the first body 2 and the second body 3. When the first body 2 and the second body 3 are in the retracted position, the first body 2 and the second body 3 are in an overlapping state.

[0056] The technical solution of this utility model adopts a dual-body and dual-tub assembly structure, combined with a clever rotating mechanism, to achieve efficient folding and multi-functional use of the washing machine. The rotating 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 to an unfolded position and a storage position. This design significantly reduces the space occupied by the washing machine during storage. This application solves the problems of inconvenience in using and storage of twin-tub washing machines in space-constrained environments in the prior art.

[0057] In this embodiment, the modular design of the washing machine is achieved by cooperating with the detachable washing tub assembly and the mounting cavity on the top of the machine body. Users can replace or clean the washing tub assembly as needed, improving the flexibility and hygiene of the washing machine. When washing is required, the user unfolds the first and second bodies to the unfolded position via the pivot mechanism, installs the washing tub assembly, and begins washing. After washing, the washing tub assembly is disassembled, and the first and second bodies are rotated to the storage position via the pivot mechanism, achieving efficient space utilization.

[0058] like Figure 1 As shown, at least two washing tub components 1 are provided, each washing tub component 1 is set independently, and each washing tub component 1 is provided with a top cover 10, a tub body, a button 12 and a handle 13. The button 12 is located on the top cover 10. By pressing the button 12, the top cover can be opened to take out and put in clothes. The handle 13 is connected to the tub body. The design of the handle 13 allows users to easily lift or move the washing tub component 1. Especially when it is necessary to remove the washing tub component from the machine body for cleaning, maintenance or moving to another location, the handle provides the necessary gripping points, making the operation more convenient.

[0059] Specifically, the rotating mechanism includes a first rotating shaft 21, a second rotating shaft 31, and a rotating shaft housing 4. The first rotating shaft 21 and the second rotating shaft 31 extend along the width direction of the machine body assembly and are arranged in parallel. At least one of the first rotating shaft 21 and the second rotating shaft 31 is rotatably connected to the rotating shaft housing 4. The first rotating shaft 21 and the second rotating shaft 31 are respectively connected to the first machine body 2 and the second machine body 3. The first machine body 2 and the second machine body 3 can switch between an unfolded position and a folded position by rotating the first rotating shaft 21 and the second rotating shaft 31. In the unfolded state, the two machine bodies are arranged in parallel, providing a stable base for the washing tub assembly 1 to perform washing operations. In the overlapping state, the two machine bodies are stacked together by the relative rotation of the first rotating shaft 21 and the second rotating shaft 31, which greatly reduces the overall size of the washing machine and facilitates storage and transportation.

[0060] Specifically, such as Figure 2 , Figure 3 As shown, the first body 2 and the second body 3 have a receiving 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 receiving 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 receiving cavity, or the first rotating shaft 21 and the second rotating shaft 31 are at least partially protruding from the receiving cavity.

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

[0062] The first pivot 21 and the second pivot 31 are key components for achieving the folding function 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 pivot 21 and the second pivot 31 can be completely located within their respective receiving cavities, or they can partially protrude from the receiving cavities (i.e., they can be designed as internal dual pivots or external dual pivots). The external dual pivot design means that the first pivot 21 and the second pivot 31 are designed to be embedded inside the washing machine main unit and are not exposed. Through the rotation of the internal pivots, the first and second main units of the washing machine can fold along a designed path, such as folding upwards or to the sides, without the exposed pivots being visible, maintaining the machine's aesthetics and neatness. The external dual pivot design means that the first pivot 21 and the second pivot 31 are at least partially located outside the body and are directly visible. This is usually done 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 may protrude along the length or width direction of the corresponding body component, at least partially located outside the receiving cavity, and not completely enclosed by the outer shell of the body component. The protruding design of the rotating shaft allows the washing machine to rotate more naturally and smoothly when folded, without being limited by the internal space of the receiving 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. Because the rotating shaft is not completely located within the receiving cavity, the internal space of the machine can be planned more efficiently and freely, providing more installation space for other core components (such as the motor). The rotating shaft portion being located outside the receiving cavity helps dissipate heat from the motor and other heat-generating components. When the washing machine is operating, the heat inside the machine can be dissipated through the contact surface between the rotating shaft and the outside, thereby reducing the internal temperature, extending the lifespan of electronic components, and improving the overall performance of the washing machine.

[0064] like Figures 4 to 8 The diagram illustrates the process of rotating the first body 2 and the second body 3 from their unfolded positions to their stowed positions. For example, the first body 2 is rotated relative to the second body 3 by a first preset angle (90°), and then rotated by a second preset angle (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 by the first preset angle in opposite directions.

[0065] Specifically, the first body 2 has a first arc-shaped surface 22 on the side closest to the second body 3, and the second body 3 has a second arc-shaped surface 32 on the side closest to the first body 2. The first arc-shaped surface 22 and the second arc-shaped surface 32 are arranged opposite each other along the length of the body assembly. When the two bodies rotate relative to each other via a pivot mechanism, that is, when the first body 2 and the second body 3 change from an unfolded state to a folded state (or vice versa), the presence of the arc-shaped surfaces can significantly reduce the contact area between the bodies, thereby reducing frictional resistance and ensuring a smoother and less strenuous folding process. The arc-shaped design can also avoid jamming or damage that may occur when hard edges are joined.

[0066] Specifically, such as Figure 9 As shown, the rotating mechanism includes a first rotating shaft 21, a second rotating shaft 31, a third rotating shaft 25, a fourth rotating shaft 35, and a rotating shaft housing 4. The first and third rotating shafts 21 and 25 are spaced apart along the width direction of the first body 2 and are coaxially arranged, rotatably relative to the first body 2. The second and fourth rotating shafts 31 and 35 are spaced apart along the width direction of the second body 3 and are coaxially arranged, rotatably relative to the second body 3. The first and third rotating shafts 21 and 25 are connected to a first side of the rotating shaft housing 4, and the second and fourth rotating shafts 31 and 35 are connected to a second side of the rotating shaft housing 4, with the first and second sides facing each other. The multi-axis design principle of the rotating mechanism is to increase the number of rotating shafts to improve the stability and flexibility of the body's folding and unfolding. The result is that the body components are more compact when folded and more stable when unfolded.

[0067] The first rotating shaft 21 and the third rotating shaft 25 are spaced apart along the width direction of the first body 2 and are coaxial, meaning they share a common centerline and can rotate synchronously, rotatably positioned relative to the first body 2. Similarly, the second rotating shaft 31 and the fourth rotating shaft 35 are spaced apart along the width direction of the second body 3 and are also coaxial, rotatably positioned relative to the second body 3. In this embodiment, the first rotating shaft 21 and the third rotating shaft 25 are connected on the first side of the rotating shaft housing 4 by a linkage, allowing them to rotate freely around a common centerline; similarly, the second rotating shaft 31 and the fourth rotating shaft 35 are similarly arranged on the second side. This design ensures that when the user operates any one of the rotating shafts, the other rotating shaft on the same side will also rotate in conjunction, thereby driving the first body 2 or the second body 3 to rotate. When the washing machine needs to be converted from an unfolded state to a folded state, the user can operate the first rotating shaft 21 or the third rotating shaft 25 to drive them to rotate by a first preset angle (90°). As the first and third rotating shafts rotate, the first body 2 begins to fold. Then drive the first rotating shaft 21 or the third rotating shaft 25 to rotate them by a second preset angle (90°). Under the guidance of the rotating shaft, the first body 2 and the second body 3 can be smoothly stacked and formed into a compact structure, which greatly saves storage space.

[0068] Specifically, at least one of the first body 2 and the second body 3 is provided with a locking part at its bottom. 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 locked together by the locking part. The locking part is provided to achieve stable locking of the first body 2 and the second body 3 in the storage state, ensuring that the washing machine will not be accidentally unfolded during storage, and ensuring the stability of the washing machine during storage or transport.

[0069] Specifically, the locking mechanism includes a first locking structure and a second locking structure. One of the first and second locking structures is located at the bottom of the first body 2, and the other is located at the bottom of the second body 3. When the washing machine is in a folded storage state, the first and second locking structures engage with each other to form a mechanical lock, preventing the machine from accidentally separating during handling or placement, ensuring the structural integrity of the washing machine, and reducing the risk of damage caused by instability. When the washing machine needs to be unfolded for use, the user can easily open and position the machine by releasing the lock between the first and second locking structures to begin the washing task.

[0070] There are several ways to implement a locking mechanism, but common methods include: The first locking mechanism can be a latch with a spring-loaded latch, typically supported by a spring or elastic material. When the mechanism is folded into place, the latch automatically pops out and engages with a slot or hole in the second locking mechanism, achieving a lock. The second locking mechanism corresponds to the first and can be a retainer with a slot or hole. The shape of the slot or hole matches the latch of the first locking mechanism, ensuring precise engagement and a secure lock.

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

[0072] When the first body 2 and the second body 3 are folded together, the first locking protrusion 23 precisely aligns with and engages with the second locking hole 34. Simultaneously, the second locking protrusion 33 also engages with the first locking hole 24. This engagement of the protrusion and hole forms a mechanical lock, ensuring a stable connection of the bodies in the folded state. The cooperation of multiple locking 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 handling or storage. The flexible design and distribution of the locking holes and protrusions allow the washing machine to adapt to washing tubs of different sizes and shapes, and to maintain stability and safety in various usage environments.

[0073] When the first body 2 and the second body 3 are in the unfolded 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 components.

[0074] Specifically, the volume of each tub in each washing tub assembly 1 can be set to be the same or different. The principle of the dual-tub adjustable volume design is to meet the different washing needs of users by providing washing tub assemblies with the same or different volumes. This improves the flexibility and efficiency of the washing machine, allowing users to select the appropriate washing tub assembly 1 according to the amount of laundry.

[0075] like Figure 12As shown, the two washing tub components 1 are arranged in a large and small configuration, suitable for living environments with limited space, such as small apartments, student dormitories, or studio apartments. This combination is very flexible in daily use; the large tub can be used to wash large items or large loads of clothing, while the small tub is suitable for washing smaller items such as underwear and socks, or clothing made of special materials, avoiding mixing with other clothes. It is primarily targeted at young users aged 18-35, including students, young professionals, singles, or small families. This demographic typically prioritizes cost-effectiveness, practicality, and convenience, while also having high requirements for hygiene and personalized washing.

[0076] like Figure 13 As shown, the two-tub washing unit 1 consists of two large tubs, suitable for scenarios requiring large-volume laundry, such as before and after family gatherings, large families, or small businesses like hotels washing employee uniforms. The two large tubs allow for simultaneous handling of large quantities of different types of laundry, improving washing efficiency and saving time. Target users include families with children, multi-generational households, and small and medium-sized enterprises with multiple employees. These individuals or businesses typically face high-frequency and large-volume laundry needs, seeking efficient and high-volume washing capabilities.

[0077] like Figure 14 As shown, the two-tub assembly 1 consists of two smaller tubs, suitable for residents in small spaces who require meticulous laundry sorting, such as families with young children. The two smaller tubs can be used separately to wash baby clothes and adult clothes, or clothes of different colors, avoiding cross-contamination and ensuring washing effectiveness and garment hygiene. It is primarily aimed at users with special requirements for laundry hygiene, such as new parents, family members with sensitive skin, and individuals with high demands for garment care. The two-tub combination not only saves space but also provides the possibility of meticulous washing, making it ideal for small families or individuals who value garment hygiene and care.

[0078] Specifically, when the first body 2 and the second body 3 are in the unfolded position, the output shafts of the motor 7 located in the first body 2 and the second body 3 are arranged parallel to each other. This parallel arrangement of the two motor output shafts ensures that the washing tubs on both sides rotate synchronously and maintain a consistent trajectory during operation, thus maintaining the overall balance of the washing machine and reducing vibration and noise caused by imbalance. The parallel output shafts can directly drive their respective washing tubs, avoiding energy loss during power transmission and improving the overall system's transmission efficiency. Furthermore, the parallel arrangement simplifies the transmission mechanism, reducing the number and complexity of transmission components, thereby lowering production costs and maintenance difficulty.

[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 located 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 first pivot 21. For example, operating the first pivot 21 rotates the first body 2 90° relative to the second body 3 along the vertical axis. This step allows the first body 2 to be laterally aligned with the second body 3. Then, continue to operate at least one of the first pivot 21 and the second pivot 31 to rotate 90° until one body can be completely located below the other body. The two bodies are tightly stacked together to form a compact structure. At this time, the first locking structure and the second locking structure, through the cooperation of the locking hole and the locking protrusion, ensure that the body is tightly locked in the storage position, preventing accidental unfolding or shaking.

[0080] Specifically, when the first body 2 and the second body 3 are in the storage position, the output shaft of the motor 7 located in the first body 2 is coaxial with the output shaft of the motor 7 located in the second body 3. The internal structure of the body components needs to fully consider the installation position of the motors and the direction of the output shafts. When the first body 2 and the second body 3 are in the storage position, the output shafts of each motor can be precisely aligned, achieving coaxiality. This coaxial storage design of the motor output shafts minimizes the overall size of the washing machine, especially in the height direction, making it easy to store even in narrow spaces.

[0081] It should be further noted that both the first body 2 and the second body 3 have knobs 6 on their outer surfaces, each knob 6 independently controlling its corresponding washing tub component 1. The knobs 6 allow users to independently select the washing program for each washing tub component. For example, a user can select a gentle wash on one side and a powerful cleaning mode on the other, meeting the washing needs of different types of clothing.

[0082] Specifically, multiple support members 200 are provided on the top of both the first body 2 and the second body 3. Each support member 200 is arranged circumferentially around the first body 2 and the second body 3, and each support member 200 at least partially protrudes from the upper surface of the first body 2 and the second body 3. When the first body 2 and the second body 3 are in the storage position, or when the first body 2 and the second body 3 are in an overlapping state, these protruding support members 200 first contact the ground, avoiding direct wear or collision on the surface of the body components, extending the service life of the washing machine, and maintaining a clean and beautiful appearance.

[0083] Specifically, the outer sides of the first body 2 and the second body 3 are also provided with a clearance part 5, which can serve as a gripping point during handling, making it easier for users to grab and control the washing machine when moving it.
