Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a frame structure for a clothing processing device and the clothing processing device itself. Background Technology

[0002] Multi-drum washing machines, with multiple drums inside the cabinet, allow for zoned washing or separate washing and drying functions, thus gaining market dominance. However, because they contain at least two drums, multi-drum machines are prone to significant vibration when multiple drums work together, especially during the spin-drying stage, which can easily lead to resonance and generate considerable noise. Furthermore, the vibration damping structure inside multi-drum washing machines is complex, occupies a large space within the cabinet, and makes it difficult to fundamentally solve the vibration and noise problems. Utility Model Content

[0003] In view of this, the present invention aims to propose a frame structure and a garment processing device to solve the problem of difficult vibration control in multi-drum washing machines in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0011] Furthermore, a first washing zone is formed between the horizontal support beam assembly and the bottom frame, and a second washing zone is formed between the top support beam assembly and the horizontal support beam assembly. The second washing zone is located above the first washing zone, and the washing capacity of the second washing zone does not exceed that of the first washing zone. The overall height of the frame structure is 900~1600mm.

[0012] Furthermore, a first washing zone is formed between the horizontal support beam assembly and the bottom frame, and a second and a third washing zone are formed between the horizontal support beam assembly and the top support beam assembly. The second and third washing zones are arranged side by side, and the overall height of the frame structure is 900~1300mm.

[0013] Furthermore, the horizontal support beam assembly includes a first horizontal support beam assembly located at the bottom and a second horizontal support beam assembly located at the top. A first washing zone is formed between the first horizontal support beam assembly and the bottom frame, a second washing zone is formed between the second horizontal support beam assembly and the first horizontal support beam assembly, and a third washing zone is provided between the second horizontal support beam assembly and the top support beam assembly. The overall height of the frame structure is 1200~1800mm.

[0014] Furthermore, the horizontal support beam assembly includes a first horizontal support beam assembly located at the bottom and a second horizontal support beam assembly located at the top. A first washing zone is formed between the first horizontal support beam assembly and the bottom frame. A second washing zone and a third washing zone are formed between the second horizontal support beam assembly and the first horizontal support beam assembly. The second and third washing zones are arranged side by side. A fourth washing zone is formed between the second horizontal support beam assembly and the top support beam assembly. The overall height of the frame structure is 1400~1800mm.

[0015] Furthermore, the inner surface of the bottom frame is smoothly formed.

[0016] Furthermore, the top support beam assembly is a closed rectangular frame, and the surfaces of the top support beam assembly facing the inner side of the frame structure are all smooth surfaces.

[0017] Furthermore, the transverse support beam assembly includes three transverse support beams, which form a semi-closed structure with an opening on the front side.

[0018] Furthermore, the horizontal support beam assembly includes three horizontal support beams, which are located on the rear side and the left and right sides of the frame structure, respectively. The horizontal support beams on the left and right sides are staggered from the support beam on the rear side.

[0019] Furthermore, the wall thickness of each beam in the top support beam assembly and the vertical support beam assembly is set to 2~4mm, and the width of each beam is set to 50~65mm.

[0027] By integrating multiple garment processing devices into a single frame structure, space utilization is maximized. Furthermore, the die-cast structure, compared to existing technologies that use multiple separate horizontal and vertical beams assembled with screws, reduces the number of parts, simplifies the assembly process, and avoids issues such as non-coplanarity between beams. This significantly improves the overall mechanical properties of the resulting high-casing frame, particularly its elongation at break, tensile strength, yield strength, and durability. In addition, the integrally die-cast frame structure of this application alters the frame's natural frequency, making it significantly higher than existing technologies and further away from the inner cylinder's rotational frequency, thus preventing resonance, enhancing overall frame strength, and reducing overall vibration and noise.

[0035] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. In addition, the orientations involved in the following specific embodiments are briefly explained: the directions or positional relationships indicated by "front," "rear," "up," "down," "left," "right," "top," and "bottom" mentioned in the embodiments refer to the orientations or positional relationships shown in the accompanying drawings. The term "on..." means directly or indirectly supported by the... element.

[0036] It should be noted that, in the description of this utility model, 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, an electrical connection, or a connection that allows for mutual communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] like Figures 1-5 As shown, a frame structure for a garment processing device includes a base frame 1, a vertical support beam assembly 2, a top support beam assembly 3, and a horizontal support beam assembly 4. The base frame 1 forms the overall bottom support structure of the frame structure. The vertical support beam assembly 2 is perpendicular to the base frame 1 and forms the vertical skeleton of the frame structure. The top support beam assembly 3 is formed on top of the vertical support beam assembly 2 and is parallel to the base frame 1. The horizontal support beam assembly 4 is formed between the base frame 1 and the top support beam assembly 3. The base frame 1, vertical support beam assembly 2, top support beam assembly 3, and horizontal support beam assembly 4 are die-cast as a single unit, and the overall height of the frame structure is 900-1800 mm. Multiple washing zones are formed inside the frame structure, with at least two washing zones arranged vertically. The washing capacity of the lowest washing zone is not less than 8 kg.

[0038] The overall height of the frame structure can be set according to the number of washing zones and the washing capacity of each zone. A rear plate 5 is provided at the rear of the frame structure, which is integrally die-cast with the frame structure. A clearance portion is provided on the rear plate 5 corresponding to the drum assembly; this clearance portion can be designed as a rearward protrusion to allow the motor to pass through. The left and right sides of the rear plate 5 are connected to two rear vertical support beams, respectively, and the lower part of the rear plate 5 is connected to the bottom frame 1. Multiple fixing holes are formed on the rear plate 5 for transport bolts to pass through, facilitating the fixing of the drum assembly during transportation. Since the transport bolts need to have high fixing strength, integrally molding the fixing holes for the transport bolts with the rear plate 5 and the frame improves the overall rigidity of the frame and rear plate 5, thereby increasing the fixing strength of the transport bolts, preventing deformation of the rear plate or fixing holes due to stress on the transport bolts, and improving the overall stability of the washing machine.

[0039] The inner surfaces of the bottom frame 1, vertical support beam assembly 2, top support beam assembly 3, and horizontal support beam assembly 4 are all smooth, which facilitates mold removal after the frame structure is die-cast, simplifies the mold structure, and improves die-casting efficiency and yield.

[0040] Both the bottom frame 1 and the top support beam assembly 3 are designed as closed rectangular frames, giving the frame an approximately symmetrical structure with uniform stress distribution, further enhancing the overall stability of the frame in supporting the cylindrical assembly and other internal components. Of the six faces formed by the frame, the corners near the center of each face are rounded, while the outer edges are right angles. These rounded corners reduce mechanical interference and friction between the product and the mold, making the ejection process smoother, reducing the risk of poor demolding, and facilitating demolding. The rounded corners also help to distribute stress at the edges. Maintaining external right angles ensures the product's aesthetic appearance and assembly accuracy, eliminating the need for additional machining to create a reference surface, thus saving subsequent processing costs and time. Furthermore, the radius of the arc-shaped chamfer structure at the inner edge corners of the left and right frames is 30~60mm. This avoids excessive stress concentration at the inner edge during die casting. The rounded corners provide a smooth stress transition path, which can evenly distribute the stress to a larger area, avoid cracking and improve the structural integrity and mechanical strength of the product. At the same time, it reduces the encapsulation force on the mold, making it easier to demold.

[0041] The width of a single beam in the top support beam assembly 3 and the vertical support beam assembly 2 in the left-right direction is 50-65 mm, preferably 60 mm. The wall thickness of each beam in the top support beam assembly 3 and the vertical support beam assembly 2 is set to 2-4 mm, which can save raw materials and reduce costs while ensuring the strength of the frame.

[0042] The horizontal support beam assembly 4 includes at least two horizontal support beams, located on the left and right frames of the frame, respectively. The left and right horizontal support beams can be on the same horizontal plane or staggered. Further, the horizontal support beam assembly 4 can also include three horizontal support beams, with the third horizontal support beam located at the rear of the frame structure. The left and right ends of the third horizontal support beam are connected to the vertical support beams at the rear left and right ends, respectively. The third horizontal support beam at the rear can be coplanar with the horizontal support beams on the left and right sides. The three horizontal support beams can form a semi-closed structure with an opening at the front or be staggered. The horizontal support beams on the left and right sides are used for hoisting the lower cylindrical assembly, installing support and vibration damping devices for the upper cylindrical assembly, and simultaneously supporting the upper cylindrical assembly and suspending the lower cylindrical assembly. Furthermore, the horizontal support beam assembly 4 can also be used to fix and support components used in clothing processing equipment such as the drying module.

[0043] As one embodiment of this utility model, a garment processing device is also provided. The garment processing device may further include a housing assembly, which includes plate-like structures such as side plates and top plates. The housing assembly is set as a sheet metal part. The housing assembly may also be integrally die-cast with the frame structure. When the housing assembly is integrally die-cast with the frame structure, the horizontal support beam may be a rib formed on each side plate and / or the rear plate, and the top support beam may be a rib or edge protruding inwardly formed on the top of the side plate and / or the rear plate.

[0044] By integrating multiple garment processing devices into a single frame structure, space utilization is maximized. Furthermore, the structure is die-cast as a single unit, which reduces the number of parts and simplifies the assembly process compared to the existing technology where multiple horizontal and vertical beams are assembled together with screws. This avoids problems such as non-coplanarity between different beams and can also change the natural frequency of the frame structure, making its natural frequency much higher than that of existing technologies and farther from the rotation frequency of the inner cylinder, thus avoiding resonance, improving the overall strength of the frame, and reducing overall vibration and noise.

[0045] To further illustrate the distribution of frame structures under different circumstances, the frame structures are divided into the following cases:

[0046] Example 1

[0047] like Figures 1-2As shown, the area formed between the horizontal support beam assembly 4 and the bottom frame 1 is the first washing zone, where the first drum assembly is installed. Correspondingly, hanging holes are provided on the horizontal support beam assembly 4 for installing lower suspension springs, which are used to suspend the first drum assembly within the first washing zone. The area formed between the top support beam assembly 3 and the horizontal support beam assembly 4 is the second washing zone, where the second drum assembly is installed. The second washing zone is located above the first washing zone, and the washing capacity of the second drum assembly does not exceed that of the first drum assembly to avoid a top-heavy situation in the garment processing equipment and to prevent tipping or violent shaking during use. Furthermore, when the frame structure forms two washing zones, the overall height of the frame structure is 900-1600 mm, the distance from the horizontal support beam assembly 4 to the lower surface of the bottom frame 1 is 600-900 mm, and the distance from the horizontal support beam assembly 4 to the top surface of the top support beam assembly 3 is 400-800 mm. The first and second washing zones are separated by the intermediate horizontal support beam assembly 4. Correspondingly, a first clearance portion is formed at the position of the first washing zone corresponding to the rear plate 5, and a second clearance portion is formed at the position of the second washing zone corresponding to the rear plate 5. The first clearance portion is used to clear the upper motor, and the second clearance portion is used to clear the lower motor.

[0048] At least six fixing holes are formed on the rear plate 5, four of which are arranged around the lower first clearance portion, and the other two are arranged on the upper left and right sides of the second clearance portion. Preferably, eight fixing holes may also be provided, that is, four fixing holes are also provided around the second clearance portion.

[0049] Example 2

[0050] like Figure 3 As shown, the structure of the first washing zone is the same as that in Embodiment 1 above.

[0051] A second and third washing zone are formed between the horizontal support beam assembly 4 and the top support beam assembly 3. The second and third washing zones are arranged side-by-side. A second drum assembly and a third drum assembly are respectively installed within the second and third washing zones. The second and third drum assemblies are basically horizontally aligned. The washing capacity of the second drum assembly is less than that of the first drum assembly, and the washing capacities of the second and third drum assemblies are basically the same. Furthermore, the washing capacity of both the second and third drum assemblies is less than 3 kg.

[0052] In this embodiment, the overall height of the frame structure is 900~1300mm.

[0053] A fixing hole is provided on the rear plate 5 corresponding to the position of the first cylinder assembly, and the fixing hole is arranged around the lower first clearance part. Since the upper second and third cylinder assemblies are small in size, the upper fixing bolts can be omitted.

[0054] Example 3

[0055] like Figure 4 As shown, the frame structure has two sets of horizontal support beam assemblies, which are distributed vertically. Specifically, there is a first horizontal support beam assembly 41 and a second horizontal support beam assembly 42. The first horizontal support beam assembly 41 and the bottom frame 1 form a first washing zone. The first washing zone contains a first drum assembly. The first horizontal support beam assembly 41 is located below the second horizontal support beam assembly 42. The second horizontal support beam assembly 42 and the first horizontal support beam assembly 41 form a second washing zone. The second washing zone contains a second drum assembly. The washing capacity of the second drum assembly is not greater than that of the first drum assembly. The second drum assembly is located above the first drum assembly.

[0056] A third washing zone is provided between the second horizontal support beam assembly 42 and the top support beam assembly 3. The third washing zone is located above the second washing zone. A third drum assembly is installed in the third washing zone. The washing capacity of the third drum assembly is no greater than that of the first drum assembly.

[0057] The central axes of the first, second, and third cylinder components are coplanar, ensuring a balanced overall structure of the garment processing equipment and preventing violent shaking caused by excessive local vibrations during use.

[0058] In this embodiment, the overall height of the frame structure is 1200~1800mm.

[0059] Example 4

[0060] like Figure 5 As shown, the frame structure has two sets of horizontal support beam assemblies, which are distributed vertically. Specifically, there is a first horizontal support beam assembly 41 and a second horizontal support beam assembly 42. The first horizontal support beam assembly 41 and the bottom frame 1 form a first washing zone. The first washing zone is equipped with a first tub assembly. The first horizontal support beam assembly 41 is located below the second horizontal support beam assembly 42. The second horizontal support beam assembly 42 and the first horizontal support beam assembly 41 form a second washing zone and a third washing zone. The second washing zone and the third washing zone are used to install the second tub assembly and the third tub assembly, respectively. The washing capacity of the second tub assembly and the third tub assembly is smaller than that of the first tub assembly. The second tub assembly and the third tub assembly are both located above the first tub assembly and are arranged side by side in the horizontal direction.

[0061] The second horizontal support beam assembly 42 and the top support beam assembly 3 form a fourth washing zone. A fourth drum assembly is installed in the fourth washing zone. The washing capacity of the fourth drum assembly is not greater than the washing capacity of the first drum assembly, but is greater than the washing capacity of the second drum assembly and the third drum assembly.

[0062] In this embodiment, the overall height of the frame structure is 1400~1800mm.

[0063] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
