Description

Technical Field

[0001] This invention relates to the field of garment processing equipment, and more particularly to a drum assembly for garment processing equipment and garment processing equipment. Background Technology

[0002] Clothing processing equipment generally adopts a sleeve structure of an outer tub and an inner tub. The outer tub and the inner tub are installed coaxially. The outer tub serves as a fixed support and also has the function of containing the medium, while the inner tub generates strong centrifugal force through high-speed rotation, thereby achieving the purpose of washing or spin-drying clothes.

[0003] In related technologies, the inner drum will undergo significant radial deformation during high-speed rotation. Therefore, a sufficient safety gap must be reserved between the inner drum and the outer drum, which restricts the further increase of the outer diameter of the inner drum, thereby limiting the effective increase of the overall volume of the garment processing equipment. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a drum assembly for a garment processing device. The garment processing device according to this invention increases washing capacity without increasing the overall size of the device, while simplifying the installation of large-sized inner drums, optimizing space utilization, and improving the user experience.

[0005] The present invention also proposes a garment processing device having the above-described bucket assembly.

[0006] The bucket assembly according to the present invention is used in a garment handling device, the bucket assembly comprising: a first end cap; a support arm, one end of which is disposed on the outer periphery of the first end cap, and the support arm is configured to be at least two spaced apart in the circumferential direction of the first end cap, a slit being defined between the circumferential edges of two adjacent support arms on the same side, and the other ends of the edges of two adjacent support arms on the same side being spaced apart to form an axial opening communicating with the slit; and a second end cap, which is disposed at the other end of the support arm and closes the opening.

[0007] According to the tub assembly of the present invention, a slit is defined between the circumferential edges of two adjacent support arms on the same side. This slit allows the inner tub to be accommodated, enabling the support arms to more flexibly adapt to the radial deformation of the inner tub during rotation. By reducing the safety clearance that must be reserved due to inner tub deformation, the internal structure of the device becomes more compact, and a larger, more spacious inner tub can be installed and used without significantly increasing the overall size of the garment handling equipment, providing a greater capacity user experience. The other ends of the edges of two adjacent support arms on the same side are spaced apart to form axial openings communicating with the slits. These axial openings facilitate the placement of the inner tub into the space enclosed between the multiple support arms during the assembly of the tub assembly. Before the openings are closed, the axial openings allow for overcoming the limitations on the size of the inner tub while maintaining the size of the space enclosed between the multiple support arms. The inner tub can be smoothly placed into the space through the openings first, or assembled with the second end cap, and then the openings can be closed, thus completing the installation process and simplifying the installation of large-sized inner tubs.

[0008] According to some embodiments of the present invention, the second end cap is detachably connected to the support arm.

[0009] According to some embodiments of the present invention, the second end cap includes: a frame, one side of which is detachably connected to the other end of the circumferential side edge of two adjacent support arms and closes the opening; and a body disposed on the other side of the frame, the outer periphery of which is detachably connected to the axial edge of the other end of the support arm.

[0010] According to some embodiments of the invention, the other end edge of the support arm is formed with a notch adapted to accommodate at least a portion of the frame.

[0011] According to some embodiments of the present invention, it further includes: a side cover disposed on the support arm and adapted to close the cut in the radial direction.

[0012] According to some embodiments of the present invention, the barrel assembly further includes a sealing assembly disposed between the support arm and the side cover to seal the cut.

[0013] According to some embodiments of the present invention, the sealing assembly includes a sealing ring disposed between the support arm and the side cover and configured as an annular ring along the edge of the cut.

[0014] According to some embodiments of the present invention, the inner radial edge of the sealing ring is formed with a first groove that opens toward the inner radial side of the sealing ring, the support arm is formed with a first protrusion surrounding the cut, the first protrusion being embedded in the first groove; and / or, the outer radial edge of the sealing ring is formed with a second groove that opens toward the outer radial side of the sealing ring, the edge of the side cover is formed with a second protrusion that is arranged around the edge, the second protrusion being embedded in the second groove.

[0015] According to some embodiments of the present invention, the sealing assembly further includes a clamping member disposed along the radial inner edge and / or the radial outer edge of the sealing ring.

[0016] In summary, the tub assembly for a garment processing device according to an embodiment of the present invention includes a first end cap and support arms. One end of each support arm is disposed on the outer periphery of the first end cap, and at least two support arms are spaced apart circumferentially from the first end cap, forming a space for accommodating an inner tub. The first end cap seals the space within the tub assembly axially, allowing the inner tub and washing medium to interact in a closed and safe environment, thereby ensuring the smooth operation of the washing process. A slit is defined between the circumferential edges of two adjacent support arms on the same side, allowing the inner tub to be avoided and enabling the support arms to more flexibly adapt to the radial deformation of the inner tub during rotation. By reducing the safety clearance that must be reserved due to inner tub deformation, the internal structure of the device is made more compact, and a larger, more spacious inner tub can be installed and used without significantly increasing the overall size of the garment processing device, providing a greater capacity user experience. The other ends of the edges on the same side of two adjacent support arms are spaced apart to form axial openings communicating with the slits, facilitating the placement of the inner tub into the space enclosed by the support arms during the assembly of the tub assembly. Before the opening is closed, it's advantageous to overcome the limitations on the inner drum size while maintaining the same space dimensions between the multiple support arms. The inner drum can be smoothly inserted into the space through the opening first, and then the opening can be closed, thus completing the installation process and simplifying the installation of large-sized inner drums. The drum assembly also includes a second end cap, located at the other end of the support arm and closing the opening. The second end cap, together with the first end cap, seals the space between the multiple support arms axially, ensuring that the washing medium and clothes interact within a closed environment and preventing leakage. Simultaneously, the second end cap seals the opening, making the drum assembly structurally intact and stable.

[0018] The garment processing apparatus according to the present invention includes the tub assembly described in any of the above embodiments. Because the garment processing apparatus according to the present invention includes the tub assembly described in any of the above embodiments, it achieves increased washing capacity, optimized internal space utilization, and simplified installation without increasing overall size, thereby improving the user experience.

[0019] According to some embodiments of the present invention, the cut includes a first cut and a second cut, the first cut and the second cut being respectively disposed on both sides of the support arm in the width direction of the garment processing device.

[0020] According to some embodiments of the present invention, the garment processing device further includes: an inner drum disposed within the support arm; a housing disposed within the housing; wherein the drum assembly further includes: a side cover disposed within the support arm and adapted to radially close the cut, the side cover being fixed to the housing.

[0052] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0053] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0054] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0055] In related technologies, the inner drum will undergo significant radial deformation during high-speed rotation. Therefore, a sufficient safety gap must be reserved between the inner drum and the outer drum, which restricts the further increase of the outer diameter of the inner drum, thereby limiting the effective increase of the overall volume of the garment processing equipment.

[0056] The following is for reference. Figures 1-19 A bucket assembly according to an embodiment of the present invention is described.

[0057] like Figures 4-19 As shown, the tub assembly according to the present invention is used in a garment processing device 1. The tub assembly includes a first end cap 131 and support arms 121. One end of the support arm 121 is disposed on the outer periphery of the first end cap 131, and the support arms 121 are configured such that at least two are spaced apart around the first end cap 131, so that the multiple support arms 121 form a space for accommodating the inner tub. The first end cap 131 is used to close the space inside the tub assembly in the axial direction, so that the inner tub 11 and the washing medium can interact in a closed and safe environment, thereby ensuring the smooth progress of the washing process.

[0058] A slit 122 is defined between the circumferential edges of two adjacent support arms 121 on the same side. The slit 122 can avoid the inner drum 11, allowing the support arms 121 to more flexibly adapt to the radial deformation of the inner drum 11 during rotation. By reducing the safety clearance that must be reserved due to the deformation of the inner drum 11, the internal structure of the equipment is made more compact, and a larger inner drum 11 with a larger volume and larger capacity can be installed and used without significantly increasing the overall size of the clothing processing equipment 1, providing a greater capacity user experience.

[0059] The other ends of the same side edges of two adjacent support arms 121 are spaced apart to form axial openings communicating with the cutout 122. The axial openings facilitate the placement of the inner cylinder 11 into the space enclosed between the multiple support arms 121 during the assembly of the barrel assembly. Before the openings are closed, the axial openings help to overcome the size limitations of the inner cylinder 11 while keeping the size of the space enclosed between the multiple support arms 12112 unchanged. The inner cylinder 11 can be smoothly placed into the space through the openings first, or the inner cylinder 11 can be assembled with the second end cap 132, and then the openings can be closed to complete the installation process of the inner cylinder 11, thus simplifying the installation difficulty of the large-sized inner cylinder 11.

[0060] The tub assembly also includes a second end cap 132, which is disposed at the other end of the support arm 121 and closes the opening. The second end cap 132, together with the first end cap 131, seals the space enclosed between the multiple support arms 121 along the axial direction of the tub assembly, ensuring that the washing medium and clothes interact within a closed environment and preventing leakage. Simultaneously, the second end cap 132 closes the opening, making the tub assembly structurally intact and stable.

[0061] Therefore, the tub assembly according to the present invention achieves increased washing capacity without increasing the overall size of the device, while simplifying the installation difficulty of large-sized inner tubs, optimizing space utilization and improving user experience.

[0062] According to some embodiments of the present invention, such as Figures 5-19 As shown, the second end cap 132 is detachably connected to the support arm 121. During production and assembly, the second end cap 132 can be removed from the support arm 121 and reinstalled, improving assembly efficiency and flexibility. Furthermore, because the second end cap 132 is detachably connected to the support arm 121, maintenance becomes simpler and more efficient in subsequent maintenance processes.

[0063] According to some embodiments of the present invention, such as Figures 5-11 As shown, the second end cap 132 includes a frame 1321. One side of the frame 1321 is detachably connected to the other end of the circumferential edge of two adjacent support arms 121 and closes the opening. The frame 1321 is used to close the opening after the inner cylinder 11 is installed in the space enclosed between the multiple support arms 121, thereby completing the installation process of the inner cylinder 11 and simplifying the installation difficulty of the large-sized inner cylinder 11.

[0064] The second end cap 132 also includes a body 1322, which is located on the other side of the frame 1321. The outer periphery of the body 1322 is detachably connected to the axial edge of the other end of the support arm 121. This allows the space enclosed between the multiple support arms 121 in the axial direction of the bucket assembly to be sealed through the detachable connection between the body 1322 and the axial edge of the other end of the support arm 121 after the inner cylinder 11 is installed and the frame 1321 closes the opening. This makes the structure of the bucket assembly complete and stable, and easy to assemble.

[0065] According to some embodiments of the present invention, such as Figures 5-8 As shown, one end edge of the support arm 121 has a notch 1211 formed to accommodate at least part of the frame 1321. Through the interlocking of the notch 1211 of the support arm 121 and the frame 1321, the installation between the frame 1321 and the support arm 121 becomes more intuitive and simple, reducing the adjustment and alignment work required during installation, while increasing the structural strength and stability of the entire barrel assembly.

[0066] According to some embodiments of the present invention, such as Figure 11 , Figure 15 and Figure 19As shown, the tank assembly also includes a side cover 14, which is disposed on the support arm 121 and adapted to close the cut 122 radially. The side cover 14 is sized to cover the cut 122, thereby closing the cut 122 and effectively preventing the medium from leaking from the cut 122, ensuring the safe operation of the equipment.

[0067] According to some embodiments of the present invention, such as Figures 1-3 As shown, the tank assembly also includes a sealing component 15, which is disposed between the support arm 12 and the side cover 14 to seal the cut 122. By providing the sealing component 15, the sealing component 15 can fit tightly with the support arm 12 and the side cover 14 respectively, effectively preventing the medium from leaking through the cut 122 from the gap between the side cover 14 and the support arm 12, thus ensuring the safe operation of the equipment.

[0068] According to some embodiments of the present invention, such as Figures 1-3 As shown, the sealing assembly 15 includes a sealing ring 151, which is disposed between the support arm 12 and the side cover 14 and is configured as an annular ring along the edge of the cutout 122. The sealing ring 151 provides a tight seal, preventing media from leaking from the cutout 122 to the outside of the device. Because the sealing ring 151 is annular, it completely surrounds the edge of the cutout 122, ensuring an effective seal.

[0069] According to some embodiments of the present invention, the radial inner edge of the sealing ring 151 is formed with a first groove opening towards the radial inner side of the sealing ring 151, and the support arm 12 is formed with a first protrusion 123 surrounding the cutout 122. The first protrusion 123 on the support arm 12 corresponds to the first groove on the sealing ring 151. By embedding the first protrusion 123 into the first groove, a secure connection is formed between the sealing ring 151 and the support arm 12, which helps to form a sealing effect between the sealing ring 151 and the support arm 12, preventing the medium from leaking from the gap between the sealing ring 151 and the support arm 12.

[0070] According to some embodiments of the present invention, such as Figure 3 As shown, the radial outer edge of the sealing ring 151 forms a second groove that opens radially outward toward the sealing ring 151, and the edge of the side cover 14 forms a second protrusion 141 that surrounds it. The first protrusion 123 on the side cover 14 corresponds to the second groove on the sealing ring 151. The second protrusion 141 is embedded in the second groove, which makes the sealing ring 151 and the side cover 14 firmly connected, which helps to form a sealing effect between the sealing ring 151 and the side cover 14, preventing the medium from leaking from the gap between the sealing ring 151 and the support arm 12.

[0071] According to some embodiments of the present invention, such as Figure 2 and Figure 3As shown, the sealing assembly 15 also includes a clamping member 152 disposed along the radial inner edge of the sealing ring 151. The clamping member 152 provides additional tightening force to ensure that the sealing ring 151 fits more firmly onto the cutout 122 of the support arm 12. When the clamping member 152 is installed, it applies a tightening force along the radial inner edge of the sealing ring 151, resulting in a tighter connection between the first groove of the sealing ring 151 and the first protrusion 123 of the support arm 12, thereby effectively preventing media leakage from the small gap between the sealing ring 151 and the support arm 12.

[0072] According to some embodiments of the present invention, the sealing assembly 15 further includes a clamping member 152 disposed along the radial outer edge of the sealing ring 151. The clamping member 152 acts at the connection between the sealing ring 151 and the side cover 14 to provide additional tightening force to ensure that the sealing ring 151 can fit more firmly against the edge of the side cover 14. When the clamping member 152 is installed, it applies a tightening force along the radial outer edge of the sealing ring 151, making the connection between the second groove of the sealing ring 151 and the second protrusion 141 of the side cover 14 tighter, thereby effectively preventing the medium from leaking from the small gap between the sealing ring 151 and the side cover 14.

[0073] According to some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the sealing assembly 15 also includes multiple locking members 152, which are respectively arranged along the radial inner edge and radial outer edge of the sealing ring 151. The locking members 152, arranged along the radial inner edge of the sealing ring 151, ensure a tighter fit between the first groove of the sealing ring 151 and the first protrusion 123 of the support arm 12. Simultaneously, the locking members 152, arranged along the radial outer edge of the sealing ring 151, strengthen the contact between the sealing ring 151 and the edge of the side cover 14, further ensuring the integrity of the seal and effectively preventing the medium from penetrating through the tiny gap between the sealing ring 151 and the side cover 14.

[0074] The following is a brief description of the garment processing device 1 according to the present invention.

[0075] The garment processing apparatus according to the present invention includes the tub assembly of any of the above embodiments. Since the garment processing apparatus according to the present invention includes the tub assembly of any of the above embodiments, the garment processing apparatus 1 according to the present invention achieves increased washing capacity, optimized internal space utilization, and simplified installation process without increasing overall size, thereby improving user experience.

[0076] According to some embodiments of the present invention, such as Figure 3As shown, the cut 122 includes a first cut and a second cut, which are respectively located on both sides of the support arm 12 in the width direction of the garment handling device 1. The first cut and the second cut together provide space for the radial deformation that may occur in the inner drum 11 during rotation, ensuring that the inner drum 11 expands accordingly on both sides in the width direction of the garment handling device 1 when deformation occurs. By setting the first cut and the second cut, the adaptability of the support arm 12 to the radial deformation of the inner drum 11 during rotation is further improved.

[0077] According to some embodiments of the present invention, such as Figure 11 , Figure 15 and Figure 19 As shown, the garment processing device 1 also includes an inner drum 11 and a housing 16. The housing 16 is used to house and protect the internal components of the garment processing device 1 and the structures required for processing garments. The inner drum 11 and the support arm 12 are disposed within the housing 16 to perform washing or drying programs within the housing 16.

[0078] The barrel assembly also includes a side cover 14, which is disposed on the support arm 121 and adapted to close the slit 122 radially. By fixing the side cover 14 to the housing 16, the position of the side cover 14 can be fixed, allowing the side cover 14 to more reliably close the slit 122 and improving the sealing performance of the equipment.

[0079] According to some embodiments of the present invention, such as Figure 2 As shown, the diameter of the inner cylinder 11 is D, and the distance between the first cut and the second cut is L, satisfying L < D. By limiting the distance L between the first cut and the second cut to be less than the diameter D of the inner cylinder 11, the size of the support arm 12 can be minimized and the capacity of the inner cylinder 11 can be increased while ensuring that the first and second cuts can effectively expand the radial deformation that the inner cylinder 11 may generate during high-speed rotation, thus improving the overall space utilization rate.

[0080] According to some embodiments of the present invention, such as Figure 2 As shown, the distance between the inner cylinder 11 and the side cover 14 is G1, and the distance between the support arm 12 and the side cover 14 is G2, satisfying G2 < G1. G1 reflects the position of the side cover 14 relative to the inner cylinder 11, while G2 reflects the position of the side cover 14 relative to the support arm 12. The smaller distance G2 between the support arm 12 and the side cover 14 provides more solid support for the support arm 12, reducing vibration caused by the high-speed rotation of the inner cylinder 11, and further improving the operational stability and safety of the equipment. The larger distance G1 between the inner cylinder 11 and the side cover 14 reserves space for radial deformation of the inner cylinder 11 during operation, ensuring that the inner cylinder 11 always maintains a safe distance from the side cover 14.
