Description

[0001] This application claims the priority of the Chinese patent application with the application number 202311753721.5 and the invention title "Drum Washing Machine" filed on December 19, 2023, the entire content of which is incorporated herein by reference. Technical Field

[0002] This application relates to the technical field of electrical appliances, and particularly to a drum washing machine. Background Art

[0003] Nowadays, more and more users tend to wash different types of clothes separately. For example, wash underwear and outerwear separately, wash light-colored clothes and dark-colored clothes separately, and so on. In this regard, the partitioned drum washing machine is widely favored because it can wash different types of clothes simultaneously.

[0004] The partitioned drum washing machine generally includes a box body, a main drum, and a sub-drum. The main drum and the sub-drum are both arranged in the box body, and the main drum and the sub-drum can operate simultaneously to wash different types of clothes.

[0005] Currently, the size of the main drum is relatively large. Limited by the space in the box body, the sub-drum is usually connected to the box body through a suspension beam and is eccentrically arranged with the main drum. This enables the energy generated during the operation vibration of the sub-drum to be directly transmitted to the box body via the suspension beam. Over time, the box body is prone to deformation, which further leads to shaking relative to the ground during operation and generates relatively large noise. Summary of the Invention

[0055] To make the objectives, technical solutions and advantages of the present application clearer, the following will further describe the implementation manners of the present application in detail with reference to the accompanying drawings.

[0056] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the field to which the present application pertains.

[0057] More and more users choose to wash different types of clothes separately (for example, wash underwear and outerwear separately). Based on this demand, the partitioned drum washing machine has gradually become the mainstream choice. The partitioned drum washing machine includes a cabinet, a main drum and a secondary drum. The main drum and the secondary drum are both arranged inside the cabinet. In the working state, the main drum and the secondary drum of the washing machine can operate simultaneously to wash different types of clothes. At present, to meet the conventional laundry needs of the main drum, the size of the main drum is usually large, which makes the size left for the secondary drum in the cabinet limited. Therefore, the secondary drum is usually connected to the cabinet through a suspension beam and is eccentrically arranged with respect to the main drum. This causes the energy generated by the vibration of the secondary drum during operation to be transmitted to the cabinet through the suspension beam. Over time, the cabinet deforms under the vibration of the secondary drum, resulting in a poor fit with the ground. Furthermore, the washing machine may slide relative to the ground during operation, generating a large amount of noise.

[0058] An embodiment of the present application provides a drum washing machine, which includes a body 1, a suspension beam assembly 2 and a first drum 3.

[0059] Among them, the main body 1 includes a box body 11. The suspension beam assembly 2 is located in the box body 11. The suspension beam assembly 2 includes a first reinforcing member 21, a second reinforcing member 22 and a suspension cross beam 23. The first reinforcing member 21 is connected to the first wall surface 111, the second reinforcing member 22 is connected to the second wall surface 112, both ends of the suspension cross beam 23 are respectively connected to the first reinforcing member 21 and the second reinforcing member 22, and the first roller 3 is connected to the suspension cross beam 23. The first wall surface 111 and the second wall surface 112 are two opposite wall surfaces in the box body 11.

[0060] In this way, the first reinforcing member 21 and the second reinforcing member 22 can absorb part of the energy generated when the first roller 3 works and vibrates, thereby reducing the amount of energy transmitted to the box body 11. The box body 11 is not easily deformed, which can extend the service life of the drum washing machine and reduce noise.

[0061] Next, each part of the drum washing machine will be introduced separately:

[0062] I. Main body 1

[0063] As Figure 1 shown, the main body 1 includes a box body 11. The main body 1 may further include a second roller (not shown).

[0064] Box 11

[0065] The box body 11 is a component in the main body 1 for accommodating the first roller 3, the suspension beam assembly 2 and the second roller (not shown).

[0066] As Figure 1 shown, the box body 11 has a cubic structure and has opposite first wall surface 111 and second wall surface 112.

[0067] The box body 11 can be formed by riveting multiple rectangular wall plates together, or by welding multiple rectangular wall plates together, or can be integrally formed by a stamping process. The embodiment of the present application does not limit the forming method of the box body 11.

[0068] In one example, referring to Figure 1 , the box body 11 is formed by riveting multiple rectangular wall plates together. The multiple rectangular wall plates enclose to form an accommodation space 12 for accommodating the suspension beam assembly 2, the first roller 3 and the second roller. When the box body 11 is formed by riveting multiple rectangular wall plates together, the first wall surface 111 and the second wall surface 112 are the two opposite wall surfaces among the two opposite wall plates.

[0069] In one example, as Figure 2As shown, the box body 11 is integrally formed by a stamping process. The rectangular plate forms the box body 11 after being stamped and bent on both sides. The box body 11 includes a first connecting portion 11a, a second connecting portion 11b, and a third connecting portion 11c. Both the first connecting portion 11a and the third connecting portion 11c are connected to the second connecting portion 11b, and the first connecting portion 11a and the third connecting portion 11c are arranged oppositely. When the box body 11 is integrally formed by a stamping process, the first wall surface 111 and the second wall surface 112 are two opposite wall surfaces in the first connecting portion 11a and the third connecting portion 11c.

[0070] Second roller

[0071] In the case where the drum washing machine is a partitioned drum washing machine, the second drum serves as the main drum in the drum washing machine, and the first drum 3 can serve as the auxiliary drum in the drum washing machine. The second drum is located inside the box body 11 and is connected to the box body 11.

[0072] In some possible embodiments, the suspension beam assembly may include a third reinforcing member and a fourth reinforcing member. The third reinforcing member is connected to the first wall surface 111, the fourth reinforcing member is connected to the second wall surface 112, and the second drum is respectively connected to the third reinforcing member and the fourth reinforcing member.

[0073] Further, the third reinforcing member may be located on the side of the first reinforcing member 21 close to the first drum 3 and connected to the first wall surface 111. The fourth reinforcing member may be located on the side of the second reinforcing member 22 close to the first drum 3 and connected to the second wall surface 112. The second drum may be respectively connected to the third reinforcing member and the fourth reinforcing member through suspension springs. That is, in the vertical direction, the third reinforcing member is disposed below the first reinforcing member 21, the fourth reinforcing member is disposed below the second reinforcing member 22, and the second drum is disposed below the first drum.

[0074] Both the third reinforcing member and the fourth reinforcing member may be the reinforcing beams for suspending the suspension springs of the second drum (i.e., the main drum) in the related art. For the specific structures of the third reinforcing member and the fourth reinforcing member, the present application will not be elaborated.

[0075] In the technical solution shown in the present application, the first drum is connected to the first reinforcing member 21 and the second reinforcing member 22 respectively through the suspension cross beam 23, while the second drum is connected to the third reinforcing member and the fourth reinforcing member respectively through suspension springs. It can be seen that the first drum and the second drum are not directly connected to a common reinforcing member, so the vibration transmission between the first drum and the second drum can be blocked, and the use stability of the drum washing machine can be improved.

[0076] Optionally, the distances from the axis of the second drum to the first wall surface 111 and the second wall surface 112 may be equal.

[0077] In this way, the connection stability between the second drum and the box body 11 can be improved.

[0078] In one example, the second drum may include an outer drum and an inner drum (both not shown). The outer drum and the inner drum both have a circular cylindrical structure. The outer drum is sleeved on the outer circle of the inner drum and is connected to the box body 11. The inner drum is rotationally connected to the outer drum and is connected to the output shaft of the motor.

[0079] In implementation, when the motor is in a working state, the output shaft of the motor rotates to drive the inner cylinder to rotate, thereby completing the washing of the clothes in the inner cylinder.

[0080] II. Suspension beam assembly 2

[0081] The suspension beam assembly 2 is a component in the drum washing machine used to suspend the first drum 3 and absorb the energy generated by the vibration of the first drum 3.

[0082] As Figure 1 and Figure 2 shown, the suspension beam assembly 2 includes a first reinforcing member 21, a second reinforcing member 22, and a suspension cross beam 23. The first reinforcing member 21, the second reinforcing member 22, and the suspension cross beam 23 are all located in the box body 11. Among them, the first reinforcing member 21 is connected to the first wall surface 111, the second reinforcing member 22 is connected to the second wall surface 112, and both ends of the suspension cross beam 23 are respectively connected to the first reinforcing member 21 and the second reinforcing member 22.

[0083] In implementation, the first drum 3 is connected to the suspension cross beam 23. The first drum 3 will generate vibration during the working state. The energy generated by the vibration is transmitted to the box body 11 via the suspension cross beam 23 and the first reinforcing member 21, or, via the suspension cross beam 23 and the second reinforcing member 22, or, the energy generated by the vibration is transmitted to the box body 11 via the suspension cross beam 23, the first reinforcing member 21, and the second reinforcing member 22 at the same time. During the energy transmission process, both the first reinforcing member 21 and the second reinforcing member 22 will absorb part of the energy, which makes the energy received by the box body 11 smaller, the box body 11 is not easily deformed, the service life of the drum washing machine can be improved, and the noise can be reduced.

[0084] In some possible embodiments, the suspension cross beam 23 has a bending structure.

[0085] In some examples, the above bending structure may be located at the end position of the suspension cross beam 23, and at least one end of the suspension cross beam 23 has a bending structure.

[0086] In one example, the first end of the suspension cross beam 23 is connected to the first reinforcing member 21, and the second end of the suspension cross beam 23 is connected to the second reinforcing member 22. Both the first end and the second end of the suspension cross beam 23 may have a bending structure.

[0087] In one example, the first end of the suspension cross beam 23 is connected to the first reinforcing member 21, and the second end of the suspension cross beam 23 is connected to the second reinforcing member 22. The first end of the suspension cross beam 23 has a bending structure.

[0088] Wherein, the first roller 3 is connected to the suspension cross beam 23, and the distance from the axis of the first roller 3 to the first end of the suspension cross beam 23 is greater than the distance from the axis of the first roller 3 to the second end of the suspension cross beam 23.

[0089] In one example, the suspension cross beam 23 may have a plate-like structure, and the above-mentioned bending structure may be formed by bending the plate-like structure twice in opposite directions.

[0090] In this example, the bending structure is formed by bending the plate-like structure twice in opposite directions. While forming the bending structure, a clearance area is also formed at the corresponding position of the bending structure. This clearance area can provide space for the installation of other components in the drum washing machine, thereby improving the space utilization efficiency in the drum washing machine.

[0091] Optionally, the angles of the above-mentioned two bends in opposite directions may both be 90°.

[0092] In this way, the forming difficulty of the bending structure can be reduced.

[0093] In the technical solution shown in this application, by setting a bending structure on the suspension cross beam 23, when the vibration of the first roller drives the suspension cross beam 23 to vibrate, the vibration of the suspension cross beam 23 and the vibration transmitted from the suspension cross beam 23 to the box wall surface can be reduced, thereby reducing the noise of the drum washing machine during use.

[0094] III. The first roller 3

[0095] When the drum washing machine is a partitioned drum washing machine, the first roller 3 serves as the auxiliary drum in the drum washing machine. The first roller 3 is located inside the box body 11 and is connected to the box body 11.

[0096] In some possible embodiments, the first roller 3 includes an outer cylinder 31 and an inner cylinder 32.

[0097] As Figure 5 shown, the first roller 3 includes an outer cylinder 31 and an inner cylinder 32. The outer cylinder 31 and the inner cylinder 32 are coaxially arranged. The outer cylinder 31 is connected to the suspension cross beam 23, and the inner cylinder 32 is located inside the outer cylinder 31 and is connected to the outer cylinder 31.

[0098] In implementation, the inner cylinder 32 is rigidly connected to the output shaft of the motor. When the motor is in a working state, the output shaft rotates to drive the inner cylinder 32 to rotate, and the washing of the clothes in the inner cylinder 32 is completed.

[0099] In one example, the outer cylinder 31 is connected to the suspension crossbeam 23 by bolts.

[0100] As Figure 3 shown, the outer cylinder 31 has a cylindrical structure. The outer wall of the outer cylinder 31 has a plurality of connecting seats 311. The connecting seats 311 have a cylindrical structure, and the axis of the connecting seat 311 is perpendicular to the axis of the outer cylinder 31. An internal threaded hole is provided on the connecting seat 311.

[0101] Exemplarily, as Figure 3 shown, a total of 4 connecting seats 311 are provided on the outer wall of the outer cylinder 31. The 4 connecting seats 311 are distributed in a matrix. Two of the 4 connecting seats 311 are located on one side of the axis of the outer cylinder 31, and the other two connecting seats 311 are located on the other side of the axis of the outer cylinder 31. An internal threaded hole is provided on each connecting seat 311.

[0102] Optionally, the connection line of the two connecting seats 311 on the same side of the axis of the outer cylinder 31 can be parallel to the axis of the outer cylinder 31. Moreover, the distance from the connection line of the two connecting seats 311 on the first side of the axis of the outer cylinder 31 to the axis of the outer cylinder 31 can be equal to the distance from the connection line of the two connecting seats 311 on the second side of the axis of the outer cylinder 31 to the axis of the outer cylinder 31.

[0103] Exemplarily, 4 through holes are provided on the suspension crossbeam 23. The 4 through holes are also distributed in a matrix and correspond to the positions of the 4 connecting seats 311 on the outer wall of the outer cylinder 31.

[0104] In implementation, the connecting seat 311 on the outer cylinder 31 is attached to the lower wall surface of the suspension crossbeam 23. After the bolt passes through the above-mentioned through hole, it is threadedly connected to the threaded hole on the connecting seat 311, realizing the detachable connection between the outer cylinder 31 and the suspension crossbeam 23.

[0105] In this way, the connection stability between the first roller 3 and the suspension crossbeam 23 can be improved.

[0106] Optionally, the external thread of the bolt and the internal thread in the threaded hole on the connecting seat 311 can both be fine pitch threads, and a fillet is provided at the root of the thread.

[0107] In this way, the stress concentration at the root of the thread can be reduced. Moreover, since the inner cylinder 32 vibrates under the drive of the motor and there is a load between the outer cylinder 31 and the suspension crossbeam 23, setting the internal thread as a fine pitch thread can enable the outer cylinder 31 and the suspension crossbeam 23 to have good self-locking performance under the action of the load, preventing the outer cylinder 31 from shaking relative to the suspension crossbeam 23 and generating noise.

[0108] Optionally, a gasket may be provided between the bolt head of the above bolt and the suspension cross beam 23. The material of the gasket may be plastic or rubber, and the embodiments of the present application do not limit this.

[0109] In this way, the connection stability between the outer cylinder 31 and the suspension cross beam 23 can be reduced.

[0110] In some possible embodiments, the wall surface of the box body 11 has a flanging structure.

[0111] As Figure 1 and Figure 2 shown, the first wall surface 111 of the box body 11 has a first flanging structure 1111 and a second flanging structure 1112 arranged oppositely, and the second wall surface 112 has a third flanging structure 1121 and a fourth flanging structure 1122 arranged oppositely.

[0112] In one example, the two ends of the first reinforcing member 21 are respectively connected to the first flanging structure 1111 and the second flanging structure 1112. The two ends of the second reinforcing member 22 are respectively connected to the third flanging structure 1121 and the fourth flanging structure 1122.

[0113] In this way, the first reinforcing member 21 is no longer directly connected to the first wall surface 111 of the box body, but is connected to the first flanging structure 1111 and the second flanging structure 1112 provided on the first wall surface 111. The first flanging structure 1111 and the second flanging structure 1112 can also participate in energy absorption, thereby reducing the amount of energy transmitted to the first wall surface 111, and the first wall surface 111 is not easily deformed. Similarly, the second reinforcing member 22 is no longer directly connected to the second wall surface 112 of the box body, but is connected to the third flanging structure 1121 and the fourth flanging structure 1122 provided on the second wall surface 112. The third flanging structure 1121 and the fourth flanging structure 1122 can also participate in energy absorption, thereby reducing the amount of energy transmitted to the second wall surface 112, and the second wall surface 112 is not easily deformed. Neither the first wall surface 111 nor the second wall surface 112 in the box body 11 is easily deformed. Furthermore, the box body can maintain its original shape without change under the action of vibration, and the fit degree between the box body 11 and the ground is always good. The washing machine will not slide relative to the ground during the working process, and thus the noise can be reduced.

[0114] Exemplarily, the two ends of the first reinforcing member 21 are respectively riveted to the first flanging structure 1111 and the second flanging structure 1112, and the two ends of the second reinforcing member 22 are respectively riveted to the third flanging structure 1121 and the fourth flanging structure 1122.

[0115] In this way, the connection stability between the first reinforcing member 21 and the flanging structure can be improved, and the stability between the second reinforcing member 22 and the flanging can also be improved.

[0116] Exemplarily, both ends of the hanging crossbeam 23 are respectively bolted to the first reinforcing member 21 and the second reinforcing member 22.

[0117] In implementation, the hanging crossbeam 23 is used to hang the first drum 3. Over a long period, deformation is likely to occur. Setting the connection method between the hanging crossbeam 23 and the first reinforcing member 21 and the second reinforcing member 22 as bolt connection can improve the efficiency of disassembling the hanging crossbeam 23.

[0118] In one example, the flanging structure can be perpendicular to the wall surface of the box body 11.

[0119] Such as Figure 2 shown, both the first flanging structure 1111 and the second flanging structure 1112 are perpendicular to the first wall surface 111. As Figure 1 shown, both the third flanging structure 1121 and the fourth flanging structure 1122 are perpendicular to the second wall surface 112.

[0120] In this way, the processing difficulty of the flanging structure can be reduced.

[0121] The flanging structure can be processed and formed by a stamping process. The embodiments of the present application do not limit the processing method of the flanging.

[0122] Optionally, both the first flanging structure 1111 and the second flanging structure 1112 can be perpendicular to the axis of the first drum 3, and both the third flanging structure 1121 and the fourth flanging structure 1122 can be perpendicular to the axis of the first drum 3.

[0123] For the first wall surface 111, when the vibration of the first drum 3 is relatively large, the first reinforcing member 21, the first flanging structure 1111 and the second flanging structure 1112 may deform. For the second wall surface 112, when the vibration of the first drum 3 is relatively large, the second reinforcing member 22, the third flanging structure 1121 and the fourth flanging structure 1122 may deform. Since the first flanging structure 1111 and the second flanging structure 1112 are distributed in the axial direction of the first drum 3, and the third flanging structure 1121 and the fourth flanging structure 1122 are also distributed in the axial direction of the first drum 3, the two edges of the first wall surface 111 located in the axial direction of the first drum 3 may move towards or away from the first drum 3. Similarly, the two edges of the second wall surface 112 located in the axial direction of the first drum 3 may move towards or away from the first drum 3. In this way, the two edges of the first wall surface 111 and the second wall surface 112 in the vertical direction will not move or the amount of movement is small, and the fitting degree between the box body 11 and the ground is always kept good. Furthermore, the washing machine is not likely to slide relative to the ground during the working process, and noise can be reduced.

[0124] In some possible embodiments, the suspension beam assembly 2 may further include a first connecting member 24 and a second connecting member 25.

[0125] As Figure 3 shown, both ends of the first connecting member 24 are respectively bolted to the first reinforcing member 21 and one end of the suspension cross beam 23. Both ends of the second connecting member 25 are respectively bolted to the second reinforcing member 22 and the other end of the suspension cross beam 23.

[0126] Referring to Figure 3 , the first connecting member 24 has a stepped plate-like structure. One end of the first connecting member 24 is in contact with the suspension cross beam 23, and the other end of the first connecting member 24 is in contact with the first reinforcing member 21. The second connecting member 25 also has a stepped plate-like structure. One end of the second connecting member 25 is in contact with the suspension cross beam 23, and the other end of the second connecting member 25 is in contact with the second reinforcing member 22.

[0127] In implementation, one end of the first connecting member 24 is bolted to the suspension cross beam 23, and the other end is bolted to the first reinforcing member 21. One end of the second connecting member 25 is bolted to the suspension cross beam 23, and the other end is bolted to the second reinforcing member 22.

[0128] In this way, the processing difficulty of the suspension cross beam 23 can be reduced.

[0129] In one example, the first wall surface 111 has a fifth flanging structure 1113. Both ends of the fifth flanging structure 1113 are respectively connected to the first flanging structure 1111 and the second flanging structure 1112.

[0130] Referring to Figure 4 , a clearance area 241 is formed by the middle part of the first connecting member 24 being recessed in a direction away from the fifth flanging structure 1113. The distance between the first wall surface 111 and the axis of the first drum 3 is greater than the distance between the second wall surface and the axis of the first drum 3.

[0131] In some possible embodiments, the first connecting member 24 and / or the second connecting member 25 has a bending structure. Since both the first connecting member 24 and the second connecting member 25 are connected to the suspension cross beam, this bending structure can reduce the vibration of the suspension cross beam 23 and the vibration transmitted from the suspension cross beam 23 to the box wall surface when the first drum vibrates, thereby reducing the noise of the drum washing machine during use. In addition, exemplarily, the bending structure of the first connecting member 24 is formed by the plate-like structure being bent twice in opposite directions. While damping vibration by bending, the clearance area 241 is formed.

[0132] In implementation, since the axis of the first drum 3 is parallel to the first wall surface 111 and the second wall surface 112, and the distance from the axis of the first drum 3 to the first wall surface 111 is greater than the distance from the axis of the first drum 3 to the second wall surface 112, therefore, the first wall surface 111 is subjected to a greater moment from the first drum 3. Compared with the second wall surface 112, the first wall surface 111 is more likely to deform.

[0133] In this way, on the premise of making full use of the space inside the drum washing machine, the structural strength of the first flanging structure 1111 and the second flanging structure 1112 can be improved.

[0134] In some possible embodiments, the stiffness of the suspension crossbeam 23 is less than the stiffness of the cabinet 11.

[0135] In implementation, the vibration amplitude transmitted from the first drum 3 to the cabinet 11 is related to the natural frequency corresponding to the connecting component between the two, and the natural frequency is positively correlated with the stiffness of the connecting component between the two. That is to say, the greater the stiffness of the suspension crossbeam 23, the greater the vibration amplitude transmitted from the first drum 3 to the cabinet 11, and the smaller the stiffness of the suspension crossbeam 23, the smaller the vibration amplitude transmitted from the first drum 3 to the cabinet 11. Therefore, setting the stiffness of the suspension crossbeam 23 to be less than the stiffness of the cabinet 11 can reduce the vibration amplitude transmitted from the first drum 3 to the cabinet 11, and thus can reduce the overall amplitude of the washing machine.

[0136] In some possible embodiments, the drum washing machine further includes a counterweight 4.

[0137] As Figure 1 shown, the counterweight 4 has a cubic structure. The counterweight 4 is located in the cabinet 11, on the side of the suspension crossbeam 23 close to the first drum 3, and is bolted to the suspension crossbeam 23.

[0138] In this way, it is equivalent to increasing the mass of the suspension crossbeam 23. In implementation, the vibration amplitude transmitted from the first drum 3 to the cabinet 11 is related to the natural frequency corresponding to the connecting component between the two, and the natural frequency is positively correlated with the mass of the connecting component between the two. That is to say, the greater the mass of the suspension crossbeam 23, the smaller the vibration amplitude transmitted from the first drum 3 to the cabinet 11, and the smaller the mass of the suspension crossbeam 23, the greater the vibration amplitude transmitted from the first drum 3 to the cabinet 11. Therefore, adding the counterweight 4 to the suspension crossbeam 23, which is equivalent to increasing the mass of the suspension crossbeam 23, can reduce the vibration amplitude transmitted from the first drum 3 to the cabinet 11, and thus can reduce the overall amplitude of the washing machine and reduce the overall amplitude and noise of the washing machine.

[0139] In one example, the counterweight 4 may be provided with a threaded hole, and an internal thread is provided in the threaded hole.

[0140] Exemplarily, the internal thread may be a fine pitch thread, the thread profile may be an equilateral triangle, and may have a rounded corner at the thread root.

[0141] In this way, stress concentration at the tooth root can be reduced. In addition, due to the vibration of the first roller 3, there is a load between the counterweight 4 and the suspension beam 23. Setting the internal thread to a fine thread can make the counterweight 4 and the suspension beam 23 have better self-locking performance under the action of load, preventing the external counterweight 4 from shaking relative to the suspension beam 23 and generating noise.

[0142] The depth of the threaded hole can be less than the thickness of the counterweight 4, and the number of the threaded holes can be multiple, and the threaded holes are located on the wall of the counterweight 4 close to the suspension beam 23, and the suspension beam 23 has multiple through holes, and the positions of the multiple through holes correspond to the positions of the threaded holes. The bolt head of the bolt is located on the side of the suspension beam 23 away from the counterweight 4, and is attached to the suspension beam 23.

[0143] In practice, the bolt can pass through the through hole and extend into the threaded hole, and the fixed connection between the counterweight 4 and the suspension beam 23 is achieved through the cooperation between the external thread on the outer wall of the bolt and the internal thread on the inner wall of the threaded hole.

[0144] In this way, the difficulty of assembling the counterweight 4 and the suspension beam 23 can be reduced.

[0145] In one example, the counterweight 4 may be provided with a connecting through hole. The number of the connecting through holes may be multiple, and the suspension beam 23 has multiple through holes, and the positions of the multiple through holes correspond to the positions of the connecting through holes.

[0146] In implementation, one end of the bolt can pass through the through hole on the suspension beam 23 and the connecting through hole in sequence, so that the bolt head abuts against the side wall of the suspension beam 23 away from the counterweight 4, and the nut and one end of the bolt are assembled together to achieve a fixed connection between the counterweight 4 and the suspension beam 23.

[0147] In this way, the processing cost of the counterweight 4 is reduced.

[0148] In one example, the counterweight 4 may have a cubic structure, and the distances from the center of mass of the counterweight 4 to the first wall 111 and the second wall 112 are equal.

[0149] Optionally, the density of the counterweight 4 may be greater than the density of the suspension beam 23 .

[0150] Exemplarily, the material of the suspension beam 23 may be super-hard aluminum, and the material of the counterweight 4 may be industrial pure iron.

[0151] In this way, the stiffness of the suspension crossbeam 23 can be made smaller, and the mass of the counterweight 4 can be made larger, so as to reduce the natural frequency of the suspension crossbeam 23 and reduce the overall amplitude and noise of the washing machine.

[0152] The technical solution provided by the embodiments of the present application at least includes the following beneficial effects:

[0153] The embodiments of the present application provide a drum washing machine. In this drum washing machine, the main body 1 includes a cabinet 11, and a suspension beam assembly 2 is located in the cabinet 11. The suspension beam assembly 2 includes a first reinforcing member 21, a second reinforcing member 22, and a suspension crossbeam 23. The first reinforcing member 21 is connected to the first wall surface 111, the second reinforcing member 22 is connected to the second wall surface 112, and the two ends of the suspension crossbeam 23 are respectively connected to the first reinforcing member 21 and the second reinforcing member 22. The first drum 3 is connected to the suspension crossbeam 23. The first wall surface 111 and the second wall surface 112 are two opposite wall surfaces in the cabinet 11. In this way, the first reinforcing member 21 and the second reinforcing member 22 can absorb part of the energy generated during the operation vibration of the first drum 3, thereby reducing the amount of energy transmitted to the cabinet 11. The cabinet 11 is not easily deformed, the service life of the drum washing machine can be extended, and the noise can be reduced.

[0154] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
