Description

Technical Field

[0001] This utility model relates to the field of household appliances, and more specifically, to a housing structure and clothing processing equipment for clothing processing. Background Technology

[0002] Front-loading washing machines have become the mainstream choice for modern families due to their gentle washing principle, water conservation, and low abrasion to clothes. However, the front door of the washing machine bears a significant load, which can easily lead to deformation and even abnormal noises over time. Furthermore, the frequency range of the washing machine's casing structure is generally less than 40Hz. However, most commonly used front-loading washing machines operate at speeds of 1200-1400 rpm, while the inner drum's rotation frequency is typically around 20Hz. The close frequency of these two components easily triggers resonance, producing additional impact sounds and abnormal noises, resulting in excessive noise levels that seriously affect the user experience and the product's market competitiveness.

[0003] Currently, the common methods for reducing vibration and noise in drum washing machines mainly include adding vibration damping structures, increasing the distribution of counterweights, and adding reinforcing ribs to the cabinet walls. However, these measures either occupy a large amount of space inside the washing machine or make the overall structure of the washing machine complex, and cannot solve the problem of vibration and noise in the washing machine from the root. Utility Model Content

[0004] In view of this, the present invention aims to propose a housing structure and garment processing equipment for garment processing, so as to solve the problems of high noise and complex assembly of existing drum garment processing equipment.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A housing structure for a garment processing device includes a U-shaped frame and a front sealing door. The front sealing door is connected to the front side of the U-shaped frame. The U-shaped frame includes a rear panel, a first side panel, and a second side panel, wherein both the first and second side panels are perpendicular to the rear panel. The U-shaped frame and the front sealing door are die-cast together as a single unit. This integral molding of the U-shaped frame reduces the number of parts, simplifies the assembly process, avoids problems such as non-coplanarity between different beams, and improves the overall strength and vibration damping performance of the frame.

[0007] Furthermore, the inner side of the connection between the front sealing door and the U-shaped frame is at least partially rounded, and the outer side of the connection between the front sealing door and the U-shaped frame is at least partially right-angled. The 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 curved chamfer also helps to distribute stress on the edge areas. 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.

[0008] Furthermore, a second mounting portion is formed on the front sealing door. The second mounting portion is located at the middle position of the front sealing door. The second mounting portion is configured to be recessed towards the rear panel. The second mounting portion is used to install the door assembly. The edge of the second mounting portion forms a stepped structure with the front sealing door body. A second damping ring is provided on the edge of the second mounting portion near the center. The second damping ring is configured to be recessed towards the rear relative to the second mounting portion.

[0009] Furthermore, a hinge connection portion is also provided on the second mounting portion. The hinge connection portion is configured to be recessed relative to the second mounting portion in the direction towards the rear plate. The hinge connection portion is located on the side close to the first side plate or the second side plate.

[0010] Furthermore, a filter mounting part is die-cast on the front sealing door. The filter mounting part is located near the lower part of the front sealing door and near the first side plate or the second side plate. The filter mounting part has a hole-like structure and is used to install a filter hole cover.

[0011] Furthermore, at least a partial rounded corner structure is provided on the inner side of the transition portion between the rear plate and the first side plate, and at least a partial rounded corner structure is also provided on the inner side of the transition portion between the rear plate and the second side plate. At least a partial right-angle structure is provided on the outer side of the connection portion between the rear plate and the first side plate and the outer side of the connection portion between the rear plate and the second side plate.

[0012] Furthermore, a first vibration damping step is formed near the center of the rear plate. The side of the first vibration damping step near the center of the rear plate is a clearance part, which protrudes rearward. A second convex surface is provided circumferentially away from the center of the rear plate on the first vibration damping step, and the second convex surface surrounds the clearance part.

[0013] Furthermore, a first reinforcing rib is provided on the outer circumferential side of the first vibration damping step. The first reinforcing rib is configured as a ring structure and surrounds the second convex surface of the first vibration damping step.

[0014] Furthermore, a second vibration damping step is provided on the outer circumferential side of the first reinforcing rib, and a gap is formed between the second vibration damping step and the first reinforcing rib.

[0015] Furthermore, a fixed edge protruding forward is provided on the top of the rear plate, and the thickness of the fixed edge in the front-rear direction is greater than the thickness of the center part of the rear plate in the front-rear direction.

[0016] Furthermore, a plurality of fixing holes are provided on the rear plate, and a stepped structure is formed between the fixing holes and the rear plate body.

[0017] A garment processing device, characterized in that it includes the housing structure of the garment processing device described above.

[0018] Compared with the prior art, the box structure of the garment processing equipment of this utility model has the following advantages:

[0019] By using a large die-cast cabinet, the natural frequency of the cabinet itself can be effectively increased, making it less prone to torsional deformation. This increases the frequency difference between the cabinet and the drum assembly, reducing the overlap in their frequencies and preventing resonance. This, in turn, lowers the risk of resonance in the laundry equipment. Furthermore, the significantly increased natural frequency of the cabinet allows for further increases in the drum assembly's speed, even up to approximately 2000 rpm, without triggering resonance between the cabinet and the drum assembly. This is beneficial for the development and widespread use of high-speed drum washing machines. Compared to traditional methods, the large die-cast cabinet integrates the side panels, rear panel, and front door into a single unit, reducing the use of screws between panels, simplifying the assembly process, and improving overall strength and rigidity. While achieving the same rigidity and strength requirements, the optimized one-piece die-cast design allows for the use of thinner angle steel or less material, resulting in a lighter overall cabinet structure.

Detailed Implementation

[0029] 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. The term "connected" means that two components are directly or indirectly fixed or attached to each other through an intermediate structure, or that the two components are integrally formed. The term "set up" means that another structure is formed or connected to a certain element.

[0030] To fundamentally solve the noise caused by resonance in drum garment processing equipment, theoretically, the natural frequency of each component needs to be reduced. However, the inner drum rotates at high speed during operation, and the higher the speed, the higher the frequency, making it difficult to adjust the natural frequency of the inner drum. Using the frequency of the inner drum's rotation as the system's natural frequency, the amplitude will increase exponentially when the external excitation frequency (of other components) approaches the system's natural frequency. Therefore, the correct strategy is to adjust the natural frequencies of key components, moving them away from the excitation frequency range, rather than simply increasing the frequencies of all components.

[0031] Currently, the main excitation sources in garment processing equipment, besides the drum, include motor vibration and water flow impact vibration. The frequency of motor vibration is generally 100~150Hz, and the frequency of water flow impact vibration is generally 2~3Hz. Both are far from the system's natural frequency and are not easy to cause resonance. Therefore, the first step is to adjust the natural frequency of the chamber to make it far away from the system's natural frequency, thereby solving the vibration and noise problem of garment processing equipment from the root.

[0032] like Figures 1-6 As shown, the garment processing equipment includes a housing 100 and a cylindrical assembly (not shown) installed inside the housing 100. The housing 100 includes a U-shaped frame 1 and a front sealing door 2. The front sealing door 2 is connected to the front side of the U-shaped frame 1. The U-shaped frame 1 is integrally formed by die casting. The material of the U-shaped frame 1 is cast iron or cast aluminum. Reinforcing members are also integrally die-cast on the front side and / or inner wall of the U-shaped frame 1. The U-shaped frame 1 and the front sealing door 2 form the housing structure of the garment processing equipment. The U-shaped frame 1 includes a rear plate 11, a first side plate 12, and a second side plate 13. The first side plate 12 and the second side plate 13 are both perpendicular to the rear plate 11 and are both connected to the edges of the first side plate 12 and the second side plate 13. The integral molding of the U-shaped frame reduces the number of parts, simplifies the assembly process, avoids problems such as non-coplanarity between different beams, and improves the overall strength and vibration reduction performance of the frame.

[0033] The inner side of the connection between the rear plate 11 and the first side plate 12 is at least partially rounded, and the inner side of the connection between the rear plate 11 and the second side plate 13 is also at least partially rounded. Correspondingly, the outer sides of the connection between the rear plate and the first side plate 12, and the outer sides of the connection between the rear plate 11 and the second side plate 13 are at least partially right-angled, but are also slightly rounded with smooth transitions to facilitate demolding. Preferably, the inner sides of the connection between the rear plate 11 and the first side plate 12, and the inner sides of the connection between the rear plate 11 and the second side plate 13 can be set with smoothly transitioning rounded corners, while the outer sides of the connection between the rear plate and the first side plate 12, and the outer sides of the connection between the rear plate 11 and the second side plate 13 can be set with right angles. 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 chamfers also have a certain effect on dispersing the force on the edge. Maintaining external right angles can ensure the product's appearance and assembly accuracy, eliminating the need for additional machining to create a reference surface, thus saving subsequent processing costs and time.

[0034] To further enhance connection stability, corner plates 111 are formed at the top of the connection between the first side plate 12 and the rear plate 11, and at the top of the connection between the second side plate 13 and the rear plate 11. The corner plates 111 are integrally formed with the entire U-shaped frame. During the die-casting of the box structure, notches are formed on the side walls of the box structure, and the cylinder assembly of the garment handling equipment is suspended within these notches by suspension springs. Furthermore, notches are formed at the top of the first side plate 12 and the second side plate 13 for suspending the suspension springs of the connecting cylinder assembly. The integrally formed U-shaped frame structure can transfer the load on the transverse support beam assembly to other components, improving support stability.

[0035] like Figure 6As shown, a clearance portion 1121 is formed on the rear plate 11. The clearance portion 1121 protrudes rearward and is used to avoid the motor assembly inside the rear plate 11. A first reinforcing rib 113 is formed at the edge of the clearance portion 1121. The first reinforcing rib 113 is annular or linear and is used to increase the strength between the clearance portion 1121 and the rear plate body. Specifically, for example, a first damping step 112 can be die-cast around the clearance portion 1121. A second convex surface 1122 is formed on the circumferential outer side of the first damping step 112. The second convex surface 1122 protrudes rearward by a smaller extent relative to the rearward protrusion of the clearance portion 1121, and the second convex surface 1122 is arranged around the clearance portion 1121. Because the clearance portion 1121 and the second convex surface 1122 have different degrees of protrusion, a first damping step 112 is formed at their connection point. This dissipates the vibration energy of the force applied to the rear plate. Furthermore, the shape of the clearance portion 1121 and the first damping step 112 can be customized according to the shape of the motor; the motor can even be pre-embedded before die-casting. A first reinforcing rib 113 is formed on the outer circumferential side of the first damping step 112. The first reinforcing rib 113 is a ring structure surrounding the second convex surface 1122 of the first damping step 112. A gap is formed between the first reinforcing rib 113 and the outer side of the second convex surface 1122 to prevent excessive concentration of stress and vibration energy at this location. A second damping step 115 is formed on the outer circumferential side of the first reinforcing rib 113, and a gap is formed between the second damping step 115 and the first reinforcing rib 113. As an optional implementation, the first damping step 112 and the second convex surface 1122 can be omitted. Instead, a first reinforcing rib 113 can be formed directly around the periphery of the clearance portion 1121. The first reinforcing rib 113 can be a ring-shaped or linear structure; for example, it can be a straight line. The first reinforcing rib 113 increases the strength between the clearance portion 1121 and other parts of the rear plate body. The straight first reinforcing rib 113 is perpendicular to the first and second side plates on the left and right sides of the clearance portion 1121, and parallel to the first and second side plates on the top and bottom sides. The first reinforcing rib 113 strengthens the motor clearance portion, preventing deformation of this part.

[0036] As an alternative, such as Figure 7 As shown, depending on the size of the motor, the clearance portion 1121 on the rear plate 11 can also be set as... Figure 7The shape shown omits the second convex surface, and the first reinforcing rib 113 is positioned close to the edge of the clearance portion 1121, forming a first damping step between the clearance portion 1121 and the first reinforcing rib 113. Similarly, the first reinforcing rib 113 can also be configured as annular or linear, and the first reinforcing rib 113 is used to increase the strength between the clearance portion 1121 and the rear plate body.

[0037] A forward-protruding fixed edge 117 is formed on the top of the rear plate 11. The thickness of the fixed edge 117 in the front-rear direction is greater than the thickness of the center part of the rear plate 11 in the front-rear direction, thereby increasing the strength and rigidity of the top of the rear plate 11. A vibration-damping transition step 116 is formed between the lower part of the fixed edge 117 and the rear plate body. The setting of the vibration-damping transition step 116 effectively decomposes and dissipates the load on the fixed edge 117 at the top of the rear plate 11, preventing the fixed edge from deforming under stress. The setting of the fixed edge 117 increases the wall thickness of the inner edge of the frame, thereby ensuring the mechanical strength of the inner side of the frame.

[0038] Multiple fixing holes 114 are formed on the back plate 11, located near the edge of the back plate 11. These fixing holes 114 are situated circumferentially outside the second vibration-damping step 115, and their edges are formed to protrude forward relative to the clearance portion 1121. This creates a stepped structure between the area around the fixing holes 114 and the back plate 11 body, reinforcing the area around the fixing holes 114. The fixing holes allow transport bolts to pass through, facilitating the fixing of the cylinder assembly during transport. Since the transport bolts require significant fixing strength, integrally forming the fixing holes 114 with the back plate 11 increases the overall rigidity of the back plate 11, thereby enhancing the fixing force of the transport bolts, preventing deformation of the back plate or fixing holes due to stress on the transport bolts, and improving the overall stability of the garment processing equipment.

[0039] Second vibration damping ribs 122, recessed into the garment processing equipment, are formed on both the first side plate 12 and the second side plate 13. Multiple second vibration damping ribs 122 are formed on the inner wall of the first or second side plate, and each second vibration damping rib 122 extends in the front-to-back direction. The multiple second vibration damping ribs 122 are arranged in an array along the vertical direction of the side plate. The second vibration damping ribs 122 on the two side plates are arranged opposite each other.

[0040] As an alternative, the second damping rib 122 can also be set as an arc-shaped rib, a vertical rib, or an inclined rib structure that is inclined along the side plate, so that the second damping ribs 122 on the two side plates remain opposite to each other.

[0041] A first fixing rib 121 is die-cast onto the first side plate 12. The first fixing rib 121 is located near the top of the first side plate 12 and extends protruding towards the second side plate 13. Two first fixing ribs 121 are provided, distributed vertically and spaced apart from each other. This arrangement strengthens the side plate and disperses vibrations. The upper first fixing rib 121 is located near the top of the first side plate, and the top of the first side plate 12 protrudes towards the second side plate 13. The load on the top of the first side plate 12 is dispersed to the lower or central part of the first side plate 12 through the first fixing rib 121, preventing deformation of the top of the first side plate. The first fixing rib 121 can also be used to connect and fix internal modules such as wiring, pipes, and drying components, avoiding the need for additional connectors, reducing the number of internal parts, and improving assembly efficiency. Alternatively, a notch or opening can be formed on the first fixing rib 121, and the cylindrical assembly of the garment processing equipment can be hung in the notch or opening by a suspension spring.

[0042] A first crossbeam 6 is die-cast between the first side plate 12 and the second side plate 13. One end of the first crossbeam 6 is connected to the first side plate 12, and the other end is connected to the second side plate 13. The first crossbeam 6 spans the front sides of the first side plate 12 and the second side plate 13. The first crossbeam 6 is designed to increase the connection strength between the first side plate 12 and the second side plate 13, preventing deformation of the front sides of the first side plate 12 and the second side plate 13 under stress. Simultaneously, the first crossbeam 6 can also be used to support and fix other components within the garment processing equipment, such as the drying module and water inlet pipes. Furthermore, the first crossbeam 6 can be configured as a bent structure, with the middle part of the first crossbeam 6 protruding forward and bent. A first damping rib 61 is also provided on the first crossbeam 6, with the first damping rib 61 protruding backward and extending along the length of the first crossbeam 6. The first damping rib 61 is used to diffuse the stress on the first crossbeam 6 and prevent the first crossbeam 6 from deforming under stress. At the same time, the configuration of the first crossbeam 6 transmits the vibration received by the first side plate to the direction of the second side plate and transmits the vibration received by the second side plate to the direction of the first side plate. The two achieve dispersion and attenuation during the transmission process.

[0043] In a preferred embodiment, the first crossbeam 6 is positioned near the top of the first side plate 12 and the second side plate 13. A lower connecting plate 4 is also provided near the lower part of the first side plate 12 and the second side plate 13. One end of the lower connecting plate 4 is connected to the first side plate 12, and the other end is connected to the second side plate 13. The lower connecting plate 4 spans the front side of the first side plate 12 and the second side plate 13. The lower connecting plate 4 is used to increase the connection strength of the lower part of the first side plate 12 and the second side plate 13, preventing deformation of the lower front part of the first side plate 12 and the second side plate 13 under stress. Simultaneously, the lower connecting plate 4 can also be used to support and fix other internal components of the garment processing equipment, such as water outlet pipes and dispensing modules. The lower connecting plate 4 can be configured as a bent structure, with the middle part of the lower connecting plate 4 bulging backward, i.e., the bending direction of the lower connecting plate 4 is opposite to the bending direction of the first crossbeam 6. A second damping rib 41 is also provided on the lower connecting plate 4 to diffuse the stress on the lower connecting plate 4 and prevent deformation of the lower connecting plate 4 under stress. Preferably, there are two second damping ribs 41, located near the upper edge of the lower plate 4 and near the lower edge of the lower plate 4, respectively, and both second damping ribs 41 extend along the length of the lower plate 4.

[0044] A lower enclosure plate 3 is also provided near the bottom of the front side of the first side plate 12 and the second side plate 13. One end of the lower enclosure plate 3 is connected to the first side plate 12, and the other end is connected to the second side plate 13. The lower enclosure plate 3 spans the bottom front side of the first side plate 12 and the second side plate 13. The lower enclosure plate 3 is provided to increase the connection strength of the first side plate 12 and the second side plate 13 near the bottom, and to prevent the bottom front side of the first side plate 12 and the second side plate 13 from deforming under stress. The lower enclosure plate 3 is a flat plate structure, and a filter hole 31 is also provided on the lower enclosure plate 3. The filter hole 31 is designed to protrude forward, so that a boss 32 is formed around the filter hole 31. The boss 32 and the flat plate of the lower enclosure plate 3 form a rib, which strengthens the filter hole 31 and reduces the noise generated by friction and vibration between the components installed at the filter hole and the lower enclosure plate. A vibration damping strip 33 is provided on the lower enclosure plate 3. The vibration damping strip 33 is located between the filter hole 31 and the first side plate 12. The vibration damping strip 33 is used to increase the strength of the lower enclosure plate 3 and attenuate and dissipate the vibration transmitted from the side plate and the bottom frame to the lower enclosure plate 3.

[0045] In this embodiment, the first crossbeam 6, the lower connecting plate 4, and the lower surrounding plate 3 are arranged sequentially from top to bottom. The vibration damping ribs on the first crossbeam 6 and the lower surrounding plate 3 have the same direction of protrusion, but the opposite direction of the vibration damping ribs on the lower connecting plate 4. When the U-shaped frame is under load, the force on the side plate is transmitted to the front side along the side plate. The vibration damping ribs on the first crossbeam, the lower surrounding plate, and the lower connecting plate 4 with opposite directions form an efficient vibration transmission path. For example, force and vibration can be transmitted and dispersed through the vibration damping ribs of the first crossbeam, and then transferred to the other side plate through the connecting node, and then transmitted downward to the lower connecting plate through the side plate. The vibration damping ribs on the lower connecting plate with the opposite direction of the first crossbeam continue to disperse the vibration. In this way, the setting of vibration damping ribs in different directions changes the stiffness and mass distribution of the U-shaped frame in different directions, so that more vibration energy is converted into heat energy dissipation during the transmission process, thereby changing the natural frequency of the entire U-shaped frame and even the entire box structure.

[0046] Furthermore, the housing of this utility model also integrally forms a bottom frame assembly 7, which is disposed at the bottom of the housing. The bottom frame assembly 7 includes a rear bottom plate, a first side bottom plate, and a second side bottom plate, wherein the first side bottom plate and the second side bottom plate are respectively disposed at the lower part of the two side plates, and the rear bottom plate is disposed at the lower part of the rear plate. The bottom frame assembly 7 is provided to increase the lower thickness of the housing, thereby improving the lower rigidity of the housing. Support feet 71 are also provided on the first bottom plate and the second bottom plate, which are used to fix the vibration damping device. The vibration damping device is connected to the cylinder assembly and provides support and vibration damping for the cylinder assembly. Preferably, the bottom frame assembly 7 also includes a front bottom plate, which is disposed at the lower front side of the housing and is integrally connected to the lower enclosure plate 3.

[0047] A front sealing door 2 is die-cast on the front side of the U-shaped frame 1, and the front sealing door 2 is parallel to the rear plate 11. When the front sealing door 2 is die-cast integrally with the U-shaped frame 1, the aforementioned first crossbeam 6, lower connecting plate 4, and lower surrounding plate 3 can be omitted, or the first crossbeam 6, lower connecting plate 4, and lower surrounding plate 3 can be die-cast integrally with the front sealing door 2. That is, a protruding structure is formed on the corresponding part of the front sealing door 2 facing the rear plate 11 to replace the aforementioned multiple parts. It is not necessary to connect the first crossbeam 6, lower connecting plate 4, and lower surrounding plate 3 with the front sealing door 2, and the overall strength of the front sealing door 2 can be guaranteed. Furthermore, the entire box 100 is integrally formed, so that the four sides around the box 100 are evenly stressed, and the load borne by the box 100 can be evenly distributed, avoiding vibration and deformation of the box.

[0048] Specifically, the inner sides of the connection points between the front sealing door 2 and the first side panel 12 and the second side panel 13 are all at least partially rounded to avoid excessive stress concentration at the connection points and to facilitate demolding. The outer sides of the connection points between the front sealing door 2 and the first side panel 12 and the second side panel 13 are all at least partially right-angled. Preferably, the inner sides of the connection points between the front sealing door 2 and the first side panel 12 and the second side panel 13 are all smoothly transitioned rounded to avoid excessive stress concentration at the connection points and to facilitate demolding. The outer sides of the connection points between the front sealing door 2 and the first side panel 12 and the second side panel 13 are all right-angled, but are also slightly rounded with a smooth transition.

[0049] A second mounting portion 22 is formed on the front sealing door 2. The second mounting portion 22 is located in the middle of the front sealing door 2 and is recessed towards the rear panel 11. The second mounting portion 22 is used to install the door assembly during assembly. The edge of the second mounting portion 22 forms a stepped structure with the body of the front sealing door 2. A second damping ring 25 is provided near the center edge of the second mounting portion 22. The second damping ring 25 is recessed rearward relative to the second mounting portion 22. The second damping ring 25 has a certain transmission and dispersion effect on the vibration and force on the front sealing door.

[0050] A hinge connection portion 24 is also provided on the second mounting portion 22. The hinge connection portion 24 is recessed towards the rear plate 11 relative to the second mounting portion 22. The hinge connection portion 24 is located on the side close to the first side plate 12 or the second side plate 13. The hinge connection portion 24 cooperates with the stepped structure on the inner and outer sides of the second mounting portion 22, which not only strengthens the front sealing door but also buffers and dissipates vibrations. Furthermore, a hinge plate assembly is formed on the hinge connection portion 24, reducing the number of parts during door assembly installation and preventing large-scale vibrations at the door assembly installation location. When installing the door assembly, it is only necessary to hook the door assembly onto the hinge connection portion.

[0051] A filter mounting part 23 is also die-cast onto the front sealing door 2. The filter mounting part 23 is located near the lower part of the front sealing door 2 and near the first side plate 12 or the second side plate 13. The filter mounting part 23 has a perforated structure, and the inner edge of the filter mounting part 23 has a stepped structure to facilitate the installation of the filter hole cover. The stepped structure also has a damping effect on the vibration of the front sealing door 2 near the lower right corner, preventing the vibration from being too concentrated near the filter hole cover. The filter hole cover corresponds to the filter hole 31 mentioned above.

[0052] As an optional embodiment of this utility model, when the housing 100 is used as the housing of a multi-drum washing machine, a first mounting portion 21 may be formed on the front door 2. The first mounting portion 21 is used for mounting the door assembly corresponding to the other drum assembly. The first mounting portion 21 and the filter mounting portion 23 are separated by a second mounting portion 22.

[0053] Furthermore, a front protruding edge 26 is formed on the top of the front sealing door 2. The front protruding edge 26 protrudes and extends towards the rear panel. The front protruding edge 26 is used to increase the strength of the top of the front sealing door 2, prevent the top of the front sealing door 2 from deforming, and at the same time distribute the load on the top of the front sealing door 2 evenly to the front sealing door body below the front protruding edge 26.

[0054] The enclosure structure of this embodiment, including all the structural details mentioned above, is integrally formed using a die-casting process. Compared with the existing technology of separate frames and side panels, or the method of connecting the front of the frame to the front door with screws, this reduces the number of parts and connecting components such as screws and rivets. The integrated design reduces assembly time to approximately 30 minutes, compared to approximately 2 hours per unit using traditional methods, significantly improving assembly efficiency. The enclosure structure in this embodiment can be made of aluminum alloy, high-silicon aluminum alloy, magnesium-aluminum alloy, or high-strength composite materials, preferably with a density of 2700 kg / m³. 3 The material used is ADC12 aluminum alloy with a Young's modulus of 71000 MPa and a Poisson's ratio of 0.33. In this embodiment, the wall thickness of the box structure is 1~4 mm, preferably 1~3.5 mm, and more preferably 2.5 mm.

[0055] The box structure is integrally die-cast using die-casting equipment. Specifically, the alloy material used for die casting is heated to a molten state in a melting furnace and degassed. A release agent is applied to the inner wall of the mold cavity. The molten metal is then injected into the casting mold, and the molten metal is pushed to fill the mold cavity according to the set process parameters. After die casting is completed, the casting cools in the mold, and then the mold is opened, with the casting being ejected from the mold by an ejection mechanism. The die-casting equipment can have a clamping force of 40,000 to 60,000 kilonewtons.

[0056] In this embodiment, the garment processing equipment can be a garment processing device, a dryer, a washer-dryer combo, or other equipment that can use the above-described housing structure.

[0057] To further verify the specific effects of the aforementioned enclosure, vibration simulation tests were conducted on enclosure structures with different structures. Simultaneously, the natural frequencies of the enclosure structures under actual conditions were measured, as detailed below:

[0058] (1) To Figure 3 The box structure shown was subjected to simulation testing. Figure 3All structural details shown are integrally die-cast. Specifically, the housing structure is made of ADC12 alloy, and the garment processing equipment is a 10KG drum garment processing device. Finite element analysis was performed using ANSYS to obtain the first-order natural frequency of the housing. The first-order natural frequency refers to the frequency corresponding to the simplest and most easily excited vibration mode of a structure during free vibration; therefore, the first-order natural frequency was used to represent the natural frequency of the housing in this test. Simulation results showed that the first-order natural frequency of the housing in this configuration is 87.56Hz.

[0059] (2) To Figure 3 The natural frequency of the enclosure structure shown was tested. Specifically, a vibrator was used to excite the enclosure of the garment processing equipment, and an accelerometer was used to measure the response. Modal parameters were then analyzed using professional software such as LMS Test.Lab. The measured first-order natural frequency of the enclosure was 54.89 Hz.

[0060] The above tests show that, compared with the existing technology where the first-order fixed frequency of the frame and other parts is generally in the range of 25~40Hz, the inherent frequency of the integrated die-cast frame structure of this application is greatly improved, which is much higher than the 25~40Hz of the existing technology, and also far away from the inner cylinder rotation frequency of 20Hz. This avoids resonance from the source, makes it less likely to occur, and reduces the overall noise of the clothing processing equipment.

[0061] 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.
