Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and specifically provides a clothing processing device. Background Technology

[0002] With technological advancements and improved living standards, people's demands for clothing care are constantly evolving. Traditional single-drum washing machines, due to the limitations of their single washing space, reveal significant shortcomings in addressing diverse washing needs. Different types, materials, colors, and individual preferences among family members necessitate multiple wash cycles in traditional single-drum washing machines, failing to meet the urgent need for precise, efficient, and personalized healthy clothing care. While multi-drum washing machines expand the washing space to some extent by adding more drums, creating conditions for categorized washing, new problems arise. The stacked layout of multiple drums results in a higher center of gravity, while the internal space is relatively compact. During operation, especially during high-speed spin-drying, this structural characteristic easily leads to severe vibrations. The noise generated by these vibrations has become a critical challenge that the entire washing machine industry urgently needs to overcome in product development and optimization.

[0003] Accordingly, there is a need in the field for a new garment handling device to address the noise and vibration problems of existing multi-tube garment handling devices. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the noise and vibration problems of existing multi-tube garment processing equipment.

[0005] In a first aspect, the present invention provides a garment processing apparatus, the garment processing apparatus comprising at least three independent washing drums, namely a first washing drum, a second washing drum and a third washing drum;

[0006] The second and third washing drums are arranged side by side above the first washing drum. The first, second, and third washing drums are fixedly connected to each other as a whole, and the first, second, and third washing drums are configured to counterweight each other.

[0007] In the optional technical solutions of the above-mentioned clothing processing equipment, the clothing processing equipment further includes a connector, and the second washing drum and the third washing drum are connected as a whole through the connector, and the whole is connected to the first washing drum.

[0008] In the optional technical solutions of the above-mentioned clothing processing equipment, the clothing processing equipment further includes a housing and a vibration damping connector, and the washing drum is connected to the housing through the vibration damping connector.

[0009] In the optional technical solutions of the above-mentioned clothing processing equipment, the vibration damping connector includes a suspension spring, the housing includes a housing body and a housing first reinforcing member, the housing first reinforcing member is respectively provided on the left and right sides inside the housing body, and the suspension spring is connected to the housing first reinforcing member.

[0010] In the optional technical solutions of the above-mentioned clothing processing equipment, the vibration damping connector includes a vibration damper, and a second housing reinforcement is provided in the lower part of the housing body, and the vibration damper is connected to the second housing reinforcement.

[0011] In the optional technical solution of the above-mentioned clothing processing equipment, the four suspension springs are respectively disposed at the top of the first washing drum, and the four vibration dampers are respectively disposed at the bottom of the first washing drum.

[0012] In the optional technical solutions of the above-mentioned clothing processing equipment, the vibration damping connector includes a suspension spring, and the side walls or rear walls of the second washing drum and the third washing drum are connected to the housing through the suspension spring.

[0013] In the optional technical solution of the above-mentioned clothing processing equipment, the housing body includes a back plate and side plates respectively disposed on the left and right sides of the back plate. The side plates and the back plate are connected to form a U-shaped structure. The first reinforcing member of the housing is respectively disposed on the left and right side plates. One end of the side plate is provided with a first folded edge. The two ends of the first reinforcing member of the housing are respectively provided with second folded edges. One second folded edge is connected to the first folded edge, and the other second folded edge is connected to the back plate.

[0014] In the optional technical solutions of the above-mentioned clothing processing equipment, the clothing processing equipment further includes a counterweight, which is disposed on the first washing drum.

[0015] In the optional technical solutions of the above-mentioned clothing processing equipment, the volume of the first washing drum is greater than that of the second washing drum and the third washing drum; and / or, the volumes of the second washing drum and the third washing drum are equal.

[0016] Those skilled in the art will understand that the garment processing device of the present invention includes at least three independent washing drums, namely a first washing drum, a second washing drum and a third washing drum; the second washing drum and the third washing drum are arranged side by side above the first washing drum, and the first washing drum, the second washing drum and the third washing drum are fixedly connected to each other as a whole, and the first washing drum, the second washing drum and the third washing drum are arranged to counterweight each other.

[0017] By employing the above technical solution, this invention fixes three independently operable washing drums together as a single unit, making them counterweights to each other. The axis connecting the three washing drums forms a triangle. Even if the second and third washing drums are not equipped with counterweights, or even if none of the three washing drums require counterweights, each washing drum can effectively resist the excitation force caused by uneven clothing distribution during operation by utilizing the overall inertia, maintaining better balance and ensuring the stability of the entire washing machine. For example, when one washing drum is in the high-speed spin-drying stage, the other washing drums will efficiently counteract unbalanced vibrations by the traction effect generated by their own mass, greatly reducing the shaking and noise generated by the washing machine during operation.

[0018] Furthermore, by significantly reducing the use of counterweights, the internal space of the casing is effectively saved. This allows the overall height of the garment processing equipment to be further reduced to below 850mm, meeting the standard height of European-style front-loading washing machines. As a result, the equipment can be easily integrated into mainstream standard cabinets, seamlessly blending into home décor without occupying extra space. Simultaneously, this equipment can be stacked and combined with dryers, shoe washers, etc., to form a multi-functional laundry and care product, further saving space and meeting the needs of modern users for efficient use of home space.

[0026] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0027] It should be noted that in the description of this invention, terms such as "center," "top," "bottom," "left," "right," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] To address the noise and vibration issues of existing multi-tube garment processing equipment, this invention proposes a garment processing device.

[0030] Reference Figure 1 and Figure 2 The garment processing equipment includes a housing 1 and at least three independent washing drums, namely a first washing drum 31, a second washing drum 32, and a third washing drum 33. The volume of the first washing drum 31 is greater than the volumes of the second washing drum 32 and the third washing drum 33. The second washing drum 32 and the third washing drum 33 are arranged side by side above the first washing drum 31. The volumes of the second washing drum 32 and the third washing drum 33 are equal.

[0031] The above-described setup allows users to select the appropriate washing drum based on the size and quantity of their clothes on a single garment processing device, thus saving water and electricity. For example, small items can be washed in a smaller drum, while larger items can be washed in a larger drum. This also prevents color bleeding and cross-contamination. Furthermore, since the garment processing device of this application includes washing drums for different sizes of clothes, there is no need to place conventional washing machines and wall-mounted washing machines in different locations in the home, thus saving floor space.

[0032] By arranging the second washing drum 32 and the third washing drum 33 side-by-side above the first washing drum 31, the vertical space of the garment processing equipment can be utilized more efficiently. This results in a compact overall structure, clear functional division, and maximizes space utilization. Furthermore, the first washing drum 31, located at the bottom of the equipment, is heavier, which effectively increases the stability of the equipment and reduces vibration during washing. The second and third washing drums 32 and 33, positioned side-by-side at the top, are relatively lighter, providing more washing space without increasing the overall center of gravity. This also helps maintain the equipment's balance and avoids instability caused by a high center of gravity. In short, this layout enhances the overall stability of the garment processing equipment. The first washing drum 31, with its larger volume, can hold more clothes and is suitable for large-volume washing tasks; the second and third washing drums 32 and 33, being smaller, are suitable for handling small amounts of clothes or performing specialized washing operations.

[0033] The second washing drum 32 and the third washing drum 33, which have equal volumes, can evenly distribute the load of clothes, ensuring a balanced load during operation, thereby improving the stability of the equipment and avoiding equipment vibration, noise or mechanical failure caused by excessive load on one side.

[0034] In one possible implementation, the first washing drum 31, the second washing drum 32, and the third washing drum 33 are fixedly connected to each other as a whole, and the first washing drum 31, the second washing drum 32, and the third washing drum 33 are configured to act as counterweights for each other. That is, two of the three washing drums are designed to act as counterweights for the other washing drum.

[0035] Mass is the sole measure of inertia, reflecting the degree to which an object resists changes in its state of motion. According to Newton's second law, under the same external force, the greater the mass of an object, the smaller its acceleration. This means that the greater the mass, the greater the inertia of the object, and the more difficult it is to change its state of motion. This invention fixes three independently operating washing drums together, with the axes of the three drums forming a triangle, making them counterweights to each other. Therefore, even without counterweights in the second and third washing drums (32 and 33), or even if none of the three drums require counterweights, each drum can effectively resist the excitation force caused by uneven clothing distribution during operation by utilizing the overall inertia, maintaining better balance and ensuring the stability of the entire washing machine. For example, when one drum is in the high-speed spin-drying stage, the other drums, through the traction generated by their own mass, efficiently counteract unbalanced vibrations, greatly reducing the shaking and noise generated during the operation of the washing machine.

[0036] Furthermore, by significantly reducing the use of counterweights, the internal space of the casing 1 is effectively saved. This allows the overall height of the garment processing equipment to be further reduced to 850mm or less, meeting the standard height of European-style drum washing machines. As a result, the equipment can be easily integrated into mainstream standard cabinets, seamlessly blending into home décor without occupying extra space. Simultaneously, this equipment can be stacked and combined with dryers, shoe washers, etc., to form a multi-functional laundry and care product, further saving space and meeting the needs of modern users for efficient use of home space.

[0037] In one possible implementation, the garment processing equipment includes a connector 6, which connects the second washing drum 32 and the third washing drum 33 to form a single unit. The top of the first washing drum 31 has two upward-protruding first fixing seats (not shown in the figure). The bottoms of the second washing drum 32 and the third washing drum 33 are respectively provided with second fixing seats 321 and third fixing seats 331. The two first fixing seats are connected to the second fixing seats 321 and the third fixing seats 331 by fasteners. Connecting the second washing drum 32 and the third washing drum 33 into a single unit increases the rigidity and integrity of this part of the structure. When the second washing drum 32 and the third washing drum 33 are fixed as a single unit before being connected to the first washing drum 31, they can better withstand external forces, reducing the shaking and displacement that may occur due to the individual connection of each washing drum, making the entire assembly more stable and reducing the risk of component damage due to vibration during operation.

[0038] As one possible implementation, the connector 6 is eliminated, and the first washing tub 31, the second washing tub 32 and the third washing tub 33 are directly connected by cladding welding, adhesive bonding or integral molding to reliably fix the three washing tubs into one unit.

[0039] Fusion welding enables the washing drums to bond at the atomic level at the joints, forming a high-strength interface that greatly improves the overall structural stability. The weld seams also provide excellent sealing, effectively preventing leakage of the washing liquid. Adhesive bonding utilizes high-performance adhesives, evenly distributed at the joints. This not only simplifies the process but also buffers the vibrations and stresses generated by the washing drums during operation, reducing equipment noise and avoiding the corrosion risks associated with metal connectors. The one-piece molding process eliminates gaps at the source, making the entire washing drum structure seamless. This achieves optimal structural strength and sealing, reduces the number of parts, lowers assembly difficulty and cost, and significantly improves the reliability and durability of the equipment.

[0040] As one possible implementation method, refer to Figure 2The garment processing equipment also includes vibration damping connectors. These connectors consist of four suspension springs 4 and four vibration dampers 5.

[0041] The four suspension springs 4 are symmetrically arranged in pairs and connected between the side of the housing 1 and the top of the first washing drum 31. The four vibration dampers 5 are also symmetrically arranged in pairs and connected between the bottom of the housing 1 and the bottom of the first washing drum 31, thus constructing an eight-dimensional vibration damping structure. Specifically, the suspension springs 4 are installed at the four corners of the top of the first washing drum 31, and the vibration dampers 5 are installed at the four corners of the bottom of the first washing drum 31.

[0042] The eight-dimensional vibration reduction design, through the cleverly arranged suspension springs 4 and vibration dampers 5, works synergistically from multiple dimensions to effectively resist such eccentric excitation. The suspension springs 4, with their elastic properties, provide buffering and support in both the vertical and horizontal directions, weakening vibration transmission. The vibration dampers 5 utilize the damping principle to rapidly dissipate vibration energy and suppress equipment swaying. Together, they significantly reduce the vibration amplitude and noise level of the entire machine during operation, creating a quiet and stable operating environment for users and significantly improving the user experience. This invention, through the fixed connection of three washing drums that act as counterweights, combined with the eight-dimensional vibration reduction mechanism design, effectively solves the problem of overall machine vibration and noise.

[0043] This invention directly connects the suspension spring 4 and the vibration damper 5 to the housing 1, eliminating the need for a traditional frame. From a cost control perspective, eliminating the dedicated load-bearing frame reduces the procurement, processing, and assembly costs of components, thus lowering the overall production cost. Regarding space utilization and size optimization, removing these additional components eliminates the need for a pre-installed frame in the housing 1, effectively reducing its overall size. This not only makes the product appearance more compact and simple but also facilitates user placement in practical applications. For example, it allows for easier integration into space-constrained home environments, improving the product's spatial adaptability. Furthermore, reducing the number of components lowers potential failure points, improves product reliability and stability, and makes subsequent maintenance more convenient.

[0044] The second and third washing drums 32 and 33 are directly supported on the first washing drum 31, sharing the suspension spring 4 and vibration damper 5. Given the relatively narrow space at the top of the smaller drum, equipping it with a separate suspension spring 4 would present numerous installation difficulties. Furthermore, installing the suspension spring 4 on the smaller drum would easily lead to collisions with the washing drum during operation, generating noise. Therefore, the separate suspension spring on the smaller drum is eliminated, freeing up the top space previously used for its installation. This saved space can be used to optimize the internal layout of the equipment, reduce its height, thereby reducing vibration and noise and improving operational stability. Moreover, eliminating the separate suspension spring on the smaller drum and reducing the likelihood of collisions between the spring and the washing drum effectively reduces noise generated during operation.

[0045] However, due to special reasons, the suspension spring 4 and the vibration damper 5 cannot be designed to be mirror-symmetrical. The suspension spring 4 and the vibration damper 5 are placed as close as possible to the front and rear edges of the first washing drum 31 in order to achieve a better vibration damping effect.

[0046] The vibration damper 5 can be of various types, including friction damping damper, hydraulic damping damper, electromagnetic damping damper, and magnetorheological fluid damping damper. This invention does not impose any restrictions on the specific type of vibration damper 5, and all types fall within the scope of protection of this invention. Furthermore, the number of vibration dampers 5 and suspension springs 4 is not limited to four. Due to special circumstances, they can also be set to two, three, five, etc., and those skilled in the art can set them according to actual needs.

[0047] As one possible implementation method, refer to Figure 1 and Figure 4 The housing 1 includes a housing body 11, a first housing reinforcement 12, and a second housing reinforcement 13. Both the first housing reinforcement 12 and the second housing reinforcement 13 are plate-shaped. The housing body 11 includes side plates 111 on the left and right sides and a back plate 112 on the rear side. The side plates 111 and the back plate 112 are connected to form a U-shaped integral structure. The side plates 111 and the back plate 112 can be integrally formed, thereby enhancing the housing's rigidity and strength. The first housing reinforcement 12 is located on the side of the housing body 11, and the second housing reinforcement 13 is located at the bottom of the housing body 11. Both the first housing reinforcement 12 and the second housing reinforcement 13 are connected and fixed to the side plates 111 and the back plate 112.

[0048] The housing 1 also includes a front panel and a top panel (not shown in the figure). The front panel is connected to the front of the housing body 11, and the top panel is connected to the top of the housing body 11.

[0049] Furthermore, continue to refer to Figure 4 The side plate 111 has a first folded edge 113 at its front end. Two housing first reinforcing members 12 are respectively disposed on the left and right side plates 111. The front and rear ends of the housing first reinforcing members 12 are respectively provided with second folded edges 121. The front second folded edge 121 is connected to the first folded edge 113 on the side plate 111, and the rear second folded edge 121 is connected to the back plate 112. The housing second reinforcing member 13 is disposed in the lower part inside the housing body 11 and is connected to the housing body 11. The suspension spring 4 is connected between the housing first reinforcing member 12 and the first washing drum 31, and the shock absorber 5 is connected between the housing second reinforcing member 13 and the first washing drum 31.

[0050] By introducing the first housing reinforcement 12 and the second housing reinforcement 13, it is unnecessary to drill holes in the housing body 11 to install the suspension spring 4, thus preventing the metal suspension spring from being exposed to external environmental corrosion and avoiding the transmission of internal noise caused by the suspension spring mounting holes. The first housing reinforcement 12 has a certain strength and toughness, providing a more stable support base for the suspension spring 4 during installation. The second housing reinforcement 12 improves the connection stability of the vibration damper 5, reduces the impact on the housing body 11, and prevents deformation of the housing body 11.

[0051] As one possible implementation, to further improve the stability of the washing drums, in addition to connecting the suspension spring 4 between the first washing drum 31 and the housing 1, the middle or rear parts of the side walls of the second washing drum 32 and the third washing drum 33 are also connected to the housing 1 via suspension springs 4. The suspension springs 4 do not occupy the space at the top of the smaller drums, thus ensuring the stability of each washing drum while saving space. Of course, those skilled in the art may, as needed, omit the suspension spring 4 connecting it only between the second washing drum 32 and the third washing drum 33 and the housing 1.

[0052] As one possible implementation, the first reinforcing member 12 and the second reinforcing member 13 of the housing are eliminated, and instead all the suspension springs 4 and shock absorbers 5 are directly connected between the first washing drum 31 and the housing body 11.

[0053] In terms of cost, removing the first reinforcing member 12 and the second reinforcing member 13 of the housing further reduces the procurement and processing steps of raw materials, lowers the cost of parts and labor assembly, and significantly reduces the overall production cost. From the perspective of space utilization, eliminating the housing reinforcing members makes the internal space layout of the housing 1 more concise and compact, eliminating the need to reserve extra space for installing the reinforcing members. This helps to further reduce the overall size of the housing 1, allowing the clothing processing equipment to better adapt to various home environments with limited space.

[0054] As one possible implementation, the axes of the suspension spring 4 and the vibration damper 5 extend as close as possible to the rotation axis of the first washing drum 31. When the axes of the suspension spring 4 and the vibration damper 5 are aligned with the rotation axis of the first washing drum 31, they can provide direct and strong buffering and damping effects in the main direction of vibration. In the vertical direction, the suspension spring 4 absorbs vertical vibration energy through its elasticity, reducing bounce. The vibration damper 5 utilizes its damping characteristics to quickly dissipate horizontal vibration energy, effectively reducing the vibration amplitude, thereby significantly reducing operating noise and creating a quiet operating environment.

[0055] Furthermore, the orientation towards the axis of rotation ensures more even force distribution in all directions, effectively resisting torsional forces and overturning moments caused by eccentricity. During the high-speed dehydration stage, the washing drum rotates at high speeds and experiences significant centrifugal force. This design ensures the equipment remains firmly fixed in place, preventing component wear or loosening due to shaking or displacement, thus extending the equipment's lifespan.

[0056] The suspension spring 4 and the shock absorber 5 can keenly sense the slight deviation of the washing drum's rotation axis and adjust the force in time. Once the washing drum deviates, the supporting force and damping force in the corresponding direction can be quickly increased or decreased to restore the washing drum to balance quickly.

[0057] As one possible implementation method, refer to Figure 2 and Figure 3 The garment handling equipment includes a front counterweight 71 and a rear counterweight 72, respectively located at the front and rear ends of the first washing drum 31. The front counterweight 71 is positioned on the left and right sides of the opening of the first washing drum 31, while the rear counterweight 72 is located at the lower part of the opening. Since the first washing drum 31 is significantly larger in volume than the second and third washing drums 32, setting a counterweight only on the first washing drum 31, combined with the mutual counterweighting of the three washing drums, is sufficient to ensure the balance and stability of the equipment during operation. The purpose of setting the counterweights is to achieve mass balance of the three washing drum assemblies in the front-to-back and left-to-right directions, while lowering the center of gravity of the drum assembly, thus better ensuring the smooth operation of the three washing drums, especially the first washing drum 31 with the largest diameter. Appropriate counterweights can enhance the washing drum's resistance to inertia, significantly reducing the overall vibration and noise of the washing machine.

[0058] Alternatively, the counterweight can be made of cast iron or concrete. Cast iron has high density and high strength, providing a large counterweight mass within a limited space, effectively enhancing the stability of the equipment. Furthermore, its good wear resistance allows it to withstand vibration and friction during long-term operation. Concrete, on the other hand, is less expensive, easier to mold, and its shape can be flexibly customized according to the structural characteristics of the first washing drum 31. It also provides some shock absorption and cushioning, helping to reduce noise and vibration during equipment operation.

[0059] It should also be noted that the location of the counterweight can be flexibly adjusted according to the actual usage scenario, equipment operating conditions, and other factors, as long as it can ensure the overall balance after the washing drum is connected and the clothing processing equipment operates stably. For example, the counterweight can be located only at the front or rear end of the first washing drum 31, or one counterweight can be located on each of the left and right sides of the first washing drum 31. Therefore, this invention does not impose any restrictions on the location, quantity, specific shape, structure, or material of the counterweight on the first washing drum 31, and all such restrictions fall within the protection scope of this invention.

[0060] Possibly, the first washing drum 31, the second washing drum 32, and the third washing drum 33 described above in this application are all outer drums, with a rotatable inner drum inside each washing drum 3. The specific implementation of rotatably locating the inner drum inside the outer drum is quite mature and will not be elaborated further. Alternatively, the inner drum can be omitted. In this case, the first washing drum 31, the second washing drum 32, and the third washing drum 33 can also be closed washing drums 3, etc. These adjustments do not deviate from the principles of this application and are all within the protection scope of this application.

[0061] As described in the first paragraph of this section, the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0062] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
