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] A front-loading washing machine consists of a cabinet and a drum assembly installed inside the cabinet. The frequency range of the cabinet structure is generally less than 40Hz. However, the rotation speed of commonly used front-loading washing machines is between 1200 and 1400 rpm, while the inner drum's rotation frequency is generally around 20Hz. The two frequencies are close, which can easily cause resonance, producing additional impact sounds and abnormal noises, leading to excessive noise problems. This seriously affects the user's living 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 connecting beams 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 for a garment processing device and a garment processing device in order to solve the problems of high noise and complex assembly of existing drum garment processing devices.

[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 plate, a first side plate, and a second side plate, wherein the first side plate and the second side plate are both perpendicular to the rear plate. The rear plate, the first side plate, and the second side plate form a U-shaped frame structure with a front opening. The U-shaped frame is integrally die-cast, and reinforcing members are integrally die-cast on the front side and / or inner wall of the U-shaped frame.

[0007] Furthermore, the reinforcing member on the front side of the U-shaped frame connects the first side plate and the second side plate, and the reinforcing member on the inner wall of the U-shaped frame is connected to the inner wall of the first side plate and / or the second side plate.

[0008] Furthermore, a first crossbeam, a lower connecting plate, and a lower surrounding plate are die-cast between the first side plate and the second side plate. The first crossbeam, the lower connecting plate, and the lower surrounding plate are distributed sequentially from top to bottom. The first crossbeam, the lower connecting plate, and the lower surrounding plate are all reinforcements on the front side of the first side plate and the second side plate. The vibration damping ribs on the first crossbeam and the lower surrounding plate have the same protrusion direction, and the vibration damping ribs on the lower connecting plate have the opposite protrusion direction.

[0009] Furthermore, a first fixing rib is also connected to the first side plate. The first fixing rib is formed on the inner wall of the first side plate. The first fixing rib is located near the top of the first side plate and is configured to protrude and extend towards the second side plate.

[0010] Furthermore, there is a transition portion between the rear plate and the first side plate, and the inner side of the transition portion has at least a partially rounded corner structure. There is also a transition portion between the rear plate and the second side plate, and the inner side of the transition portion has at least a partially rounded corner structure.

[0011] Furthermore, the outer side of the connection between the rear plate and the first side plate, and the outer side of the connection between the rear plate and the second side plate, are at least partially right-angled structures.

[0012] Furthermore, a clearance portion is provided on the rear plate, the clearance portion protrudes rearward, and a first reinforcing rib is located at the edge of the clearance portion, the first reinforcing rib being at least partially annular or linear.

[0013] Furthermore, a forward-protruding fixing edge is formed on the top of the rear plate, and the thickness of the fixing edge in the front-rear direction is greater than the thickness of the center part of the rear plate in the front-rear direction.

[0014] Furthermore, multiple fixing holes are formed on the rear plate, located near the edge of the rear plate, and transport bolts are disposed in the fixing holes.

[0015] Furthermore, the U-shaped frame is integrally formed with a bottom frame assembly, which is connected to the bottom of the U-shaped frame. The bottom frame assembly is also integrally die-cast with a support foot, which is used to fix the vibration damping device.

[0016] This utility model also provides a garment processing device, including the box structure described above.

[0017] Compared with the prior art, the housing structure and garment processing equipment of this utility model have the following advantages:

[0018] By integrating reinforcement components into the large die-cast U-shaped frame, the natural frequency of the cabinet structure is effectively increased. This makes the cabinet less prone to torsional deformation, increases the frequency difference between the cabinet structure and the drum assembly, reduces the overlap in their frequencies, and avoids resonance with the drum assembly, thereby lowering the risk of resonance in the clothes handling equipment. Furthermore, because the natural frequency of the cabinet structure is significantly increased, the drum assembly speed can be further increased, even to around 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.

[0019] Furthermore, the large die-cast U-shaped frame integrates multiple crossbeams, vertical beams, side plates, and rear plates into a single structure, reducing the number of parts, simplifying the assembly process, and improving overall strength and rigidity compared to traditional methods.

Detailed Implementation

[0027] 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.

[0028] To fundamentally solve the noise caused by resonance in a drum washing machine, theoretically, the natural frequency of each component needs to be lowered. However, the inner drum rotates at high speed, 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 (other component) excitation frequency 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.

[0029] Currently, the main excitation sources in washing machines, 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 likely to cause resonance. Therefore, the first step is to adjust the natural frequency of the cabinet to keep it away from the system's natural frequency, thereby solving the washing machine vibration noise problem at its root.

[0030] like Figures 1-4 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 front sealing door 2 is a sheet metal part or an injection molded part. 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 edge of the rear plate 11. The rear plate 11, the first side plate 12, and the second side plate 13 form a U-shaped frame structure with a front opening.

[0031] There is a transition section between the rear plate 11 and the first side plate 12, with the inner side of the transition section having at least a partially rounded corner structure. There is also a transition section between the rear plate 11 and the second side plate 13, with the inner side of the transition section having at least a partially rounded corner structure. The outer sides of the connection points between the rear plate 11 and the first side plate 12, and between the rear plate 11 and the second side plate 13, are at least partially right-angled structures. Specifically, the inner side of the connection point between the rear plate 11 and the first side plate 12 is provided with a smoothly transitioning rounded corner structure, and the inner side of the connection point between the rear plate 11 and the second side plate 13 is also provided with a smoothly transitioning rounded corner structure. Correspondingly, the outer sides of the connection points between the rear plate 11 and the first side plate 12, and between the rear plate 11 and the second side plate 13, are provided with right-angled structures, but also with slightly rounded corner structures that are smoothly transitioning. 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. In addition, the rounded corners have a certain effect on dispersing the force on the edge parts. The structure of maintaining external right angles and small rounded corners can ensure the aesthetic appearance and assembly accuracy of the product. There is no need to carry out additional machining to create a reference surface, saving subsequent processing costs and time.

[0032] 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.

[0033] like Figure 4As 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 structure or a linear structure, such as 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 and prevents deformation of this part.

[0034] As an alternative, such as Figure 5 As shown, depending on the size of the motor, the clearance portion 1121 on the rear plate 11 can also be set as... Figure 5The 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 a ring or a line, and the first reinforcing rib 113 is used to increase the strength between the clearance portion 1121 and the rear plate body.

[0035] 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.

[0036] 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 located circumferentially outside the second damping step 115, and the edges of the fixing holes 114 are formed to protrude forward relative to the clearance portion 1121, creating a stepped structure between the area around the fixing holes 114 and the back plate 11 body, thus reinforcing the area around the fixing holes 114. The fixing holes are used for transport bolts to pass through, facilitating the fixing of the cylinder assembly during transport. Since the transport bolts require high fixing strength, the fixing holes 114 for fixing the transport bolts are integrally formed with the back plate 11 and the U-shaped frame 1. This improves the overall rigidity of the U-shaped frame 1 and the back plate 11, thereby increasing 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.

[0037] 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.

[0038] 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 are symmetrical.

[0039] A first fixing rib 121 is integrally formed on the first side plate 12, and the first fixing rib 121 is formed on the inner wall of the first side plate or the first side plate 12. The first fixing rib 121 is located near the top of the first side plate 12, and the first fixing rib 121 is configured to protrude and extend towards the second side plate 13. There are two first fixing ribs 121, and the two first fixing ribs 121 are distributed vertically and separated from each other. While strengthening the side plate, they also disperse the vibrations received by the side plate. The first fixing rib 121 located at the upper part is close to the top of the first side plate, and the top of the first side plate 12 is configured to protrude towards the second side plate 13. The load on the top of the first side plate 12 is dispersed to the lower part or the center of the first side plate 12 through the first fixing rib 121, avoiding deformation of the top of the first side plate. The first fixing rib 121 can also be used to fix the wiring, pipes, drying components and other modules inside the box structure, avoiding the need for additional connectors, reducing the number of internal parts of the box and improving assembly efficiency. Alternatively, a notch or opening can be formed on the first fixing rib 121, and the cylinder assembly of the garment processing equipment can be hung in the notch or opening via a suspension spring. This reduces the number of connecting parts for fixing the suspension spring, facilitates the assembly of the cylinder assembly, and increases the connection strength between the suspension spring and the housing, preventing the suspension spring or cylinder assembly from falling off.

[0040] A first crossbeam 6 is formed 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 provided to increase the connection strength between the first side plate 12 and the second side plate 13, and to prevent the front sides of the first side plate 12 and the second side plate 13 from deforming under stress. At the same time, the first crossbeam 6 can also be used to support and fix other components inside the clothing processing equipment, such as the drying module, water inlet pipes, and other components. 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 formed 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.

[0041] In a preferred embodiment, the first crossbeam 6 is located near the top of the first side plate 12 and the second side plate 13. A lower connecting plate 4 is also connected to 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 provided to increase the connection strength of the lower part of the first side plate 12 and the second side plate 13, and to prevent the lower front part of the first side plate 12 and the second side plate 13 from deforming under stress. At the same time, the lower connecting plate 4 can also be used to support and fix other components inside the clothing 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 and bent backward, that is, 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 connected to the lower connecting plate 4 to diffuse the stress on the lower connecting plate 4 and prevent the lower connecting plate 4 from deforming 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.

[0042] A lower enclosure plate 3 is formed 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 designed to increase the connection strength of the first side plate 12 and the second side plate 13 near the bottom, preventing 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 has a flat plate structure and a filter hole 31 is 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 damping strip 33 is connected to the lower enclosure plate 3. The damping strip 33 is disposed between the filter hole 31 and the first side plate 12. The 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.

[0043] 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.

[0044] Furthermore, the U-shaped frame 1 of this utility model is integrally formed with a bottom frame assembly 7, which is disposed at the bottom of the U-shaped frame 1. The bottom frame assembly 7 includes a first side bottom plate, a second side bottom plate, and a rear 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 of the U-shaped frame 1. The bottom frame assembly 7 is provided to increase the lower thickness of the U-shaped frame 1, thereby improving the lower stiffness of the U-shaped frame 1. Support feet 71 are also provided on the first side bottom plate and the second side bottom plate. The support feet 71 are used to fix the vibration damping device, which is connected to the cylinder assembly and plays a supporting and vibration damping role for the cylinder assembly. Preferably, the bottom frame assembly 7 also includes a front bottom plate, which is disposed at the front side of the U-shaped frame 1 and is integrally connected with the lower surrounding plate 3.

[0045] In this embodiment, the U-shaped frame 1, including all the structural details mentioned above, is integrally formed by die casting. Compared with the existing technology of separate frames and side plates connected by screws, this reduces the number of parts and connecting components such as screws and rivets. The overall integrated design reduces the assembly time to about 40 minutes, compared with the traditional process of about 2 hours per unit, greatly improving assembly efficiency.

[0046] In this embodiment, the material of the U-shaped frame 1 can be aluminum alloy, high-silicon aluminum alloy, magnesium-aluminum alloy, or high-strength composite material, preferably with a density of 2700 kg / m³. 3 The aluminum alloy used is ADC12, which has a Young's modulus of elasticity of 71,000 MPa and a Poisson's ratio of 0.33. The front sealing door structure connected to the U-shaped frame uses commonly used sheet metal materials, such as pre-coated steel sheet (PCM).

[0047] The U-shaped frame 1 is integrally die-cast using die-casting equipment. Specifically, the alloy material used for die casting is injected into the casting mold. The die-casting machine can have a clamping force of 40,000 to 60,000 kilonewtons.

[0048] To further verify the specific effects of the aforementioned frame, vibration simulation tests were conducted on U-shaped frames 1 with different structures. The natural frequencies of the frame under actual conditions were also measured, as follows:

[0049] (1) To Figures 1-2 The U-shaped frame shown was used for simulation testing. Figures 1-2 All structural details shown are integrally die-cast. Specifically, the U-shaped frame 1 is made of ADC12 alloy, and the garment processing equipment is a 10KG drum washing machine. A front door is fixedly connected to the front of the U-shaped frame, and the front door is made of PCM color-coated steel sheet. Finite element analysis was performed using ANSYS to obtain the first-order natural frequency of the U-shaped frame. 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 U-shaped frame in this test. After simulation testing, the first-order natural frequency of the U-shaped frame in this form was found to be 72.47Hz.

[0050] (2) To Figure 3 The U-shaped frame shown was subjected to simulation testing. Unlike (1) above, the U-shaped frame tested in this test had no reinforcing members, vibration damping ribs or other structures, and the other test conditions were the same as those in (1) above. After simulation testing, the first-order fixed frequency of the frame in this form was found to be 54.65-12 Hz.

[0051] The above tests show that, compared with the existing technology where the first-order fixed frequency of the box frame and other parts is generally in the frequency range of 25~40Hz, the inherent frequency of the U-shaped frame structure of this application, which is made of one piece of die casting, is greatly improved, far exceeding the 25~40Hz of the existing technology, and is 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.

[0052] In this embodiment, the clothing handling equipment can be a washing machine, dryer, washer-dryer combo, or other equipment that can use the above-mentioned U-shaped frame.

[0053] 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.
