Description

Technical Field

[0001] The invention relates to the field of household appliances, and in particular to a spring-loaded crossbeam and a frame of a clothes processing device which are convenient to assemble. Background Art

[0002] The internal structures of existing clothing processing equipment are various. The complex internal structures will make the assembly process complicated, the assembly efficiency of workers is low, and the production cost is increased. Existing clothing processing equipment, such as washing machines and dryers, includes a frame, a clothing processing drum, and the clothing processing drum includes an outer barrel and an inner barrel rotatably arranged in the outer barrel. The upper part of the outer barrel is hung on a spring load-bearing beam on a reinforcement member fixed to the frame through a suspension spring, and the bottom of the outer barrel is supported by a support spring at the bottom of the frame.

[0003] The existing spring load-bearing crossbeam is respectively provided with a screw hole on both sides so as to be fixed to the sheet metal of the frame by fasteners. Firstly, only one fixing structure (screw hole) is provided on one side of the spring load-bearing crossbeam, and the fixing effect is not good. Especially during transportation or violent movement of the inner barrel, the fixing structures on both sides of the spring load-bearing crossbeam are easily forced to separate from the frame, thereby causing safety accidents. On the other hand, the structure on the existing spring load-bearing crossbeam is an asymmetric design. During the actual installation process, the operator needs to adjust its position for installation. The operator needs to adjust its front and back sides and left and right sides to perform a suitable installation, that is, the spring load-bearing crossbeam can only be fixed on the reinforcement on the frame in one posture position. Therefore, in actual work, the operator's assembly time needs to be wasted. The operator must first distinguish its posture position and adjust the position of the spring load-bearing crossbeam before positioning and installing it.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a spring load-bearing beam, wherein a first connecting structure and a second connecting structure are respectively provided on the upper and lower sides, and the spring load-bearing beam is connected and fixed to a reinforcement member on the frame of a clothing processing device through the first connecting structure and / or the second connecting structure. When the spring load-bearing beam is fixed to the reinforcement member on the frame through the first connecting structure and the second connecting structure at the same time, the fixing effect of the spring load-bearing beam is improved. When the first connecting structure and the second connecting structure are symmetrical up and down, the spring load-bearing beam is universal on the left and right. In the actual assembly process, there is no need to distinguish the left and right positions of the spring load-bearing beam, and only the front and back sides of the load-bearing beam need to be distinguished, thereby saving the time for adjusting the position of the load-bearing beam during the installation process and improving work efficiency.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A spring-loaded crossbeam comprises a long strip body, a first connecting structure is arranged on the upper side of the body, a second connecting structure is arranged on the lower side of the body, and the body is connected and fixed to a reinforcement member on the frame of a clothing processing device through the first connecting structure and / or the second connecting structure.

[0008] In the above scheme, the main body can be connected and fixed to the reinforcement on the frame of the clothing processing equipment through the first connecting structure and / or the second connecting structure. When the main body is fixed to the reinforcement on the frame through the first connecting structure and the second connecting structure at the same time, the fixing stability of the spring-loaded beam is improved.

[0009] Preferably, the first connection structure includes two connection structures respectively located at the two ends of the upper side of the main body, and the second connection structure includes two connection structures respectively located at the two ends of the lower side of the main body; wherein the first connection structure and the second connection structure can adopt the same connection structure or different connection structures.

[0010] Preferably, the first connecting structure and the second connecting structure are connecting structures with the same structure.

[0011] Preferably, the two connection structures of the first connection structure and the two connection structures of the second connection structure are symmetrically arranged on the upper and lower sides of the main body.

[0012] In the above scheme, when the first connecting structure and the second connecting structure are symmetrical up and down, the spring load-bearing beam can be used for both left and right sides. During the actual assembly process, there is no need to distinguish the left and right positions of the spring load-bearing beam, but only the front and back sides of the load-bearing beam need to be distinguished, thereby saving time in adjusting the position of the load-bearing beam during the installation process and improving work efficiency.

[0013] Preferably, the first connection structure includes through holes provided at both ends of the upper side of the body, and the upper side of the body is fixed to the reinforcement member on the frame through fasteners passing through the through holes, or the first connection structure includes contact portions of the reinforcement member on the frame at both ends of the upper side of the body, and the contact portions are welded and fixed to the corresponding reinforcement member;

[0014] And / or, the second connection structure includes through holes arranged at the two end edges of the lower side of the main body, and the lower side of the main body is fixed to the reinforcement on the frame by fasteners passing through the through holes, or the second connection structure includes a contact portion of the reinforcement on the frame located at the two end edges of the lower side of the main body, and the contact portion is welded and fixed to the corresponding reinforcement.

[0015] Preferably, a first spring hanging portion is provided on the main body corresponding to the first connecting structure, and a second spring hanging portion is provided corresponding to the second connecting structure. The first spring hanging portion and the first connecting structure are located on the same side of the main body, and the second spring hanging portion and the second connecting structure are located on the same side of the main body.

[0016] In the above scheme, when the spring load-bearing cross beam is fixed to the reinforcement member on the frame with the first connection structure, the first spring hanging portion is suitable for hanging the spring, and when the spring load-bearing cross beam is fixed to the reinforcement member on the frame with the second connection structure, the second spring hanging portion is suitable for hanging the spring;

[0017] Alternatively, when the first connection structure and the second connection structure of the spring load-bearing cross beam are both fixed to the reinforcement member on the frame, the spring is hung by the spring hanging portion corresponding to the first or second connection structure at a higher position.

[0018] Preferably, the two spring hanging parts are symmetrically arranged on the main body, and are used for hanging the spring by the spring hanging part corresponding to the first connecting structure / second connecting structure at a higher position after the spring load-bearing crossbeam is fixed to the reinforcement member on the frame;

[0019] In the above scheme, by arranging the two spring hanging parts symmetrically up and down, the first spring hanging part and the second spring hanging part are respectively suitable for hanging the spring by the first spring hanging part when the first connecting structure is higher than the second connecting structure, and hanging the spring by the second spring hanging part when the second connecting structure is higher than the first connecting structure.

[0020] Preferably, the middle surface of the body along its length direction is stamped to one side to form a strip-shaped protrusion, the two spring hanging parts include two notches symmetrically opened on the protrusion, and the first connection structure and the second connection structure are respectively arranged on the plane structure on the upper side and the plane structure on the lower side of the protrusion on the body. Preferably, the side wall and top wall surface of the protrusion are formed with irregular structures: including multiple planes of different heights, each plane has a smooth or non-smooth transition.

[0021] In the above scheme, the protrusion is an irregular structure, which is conducive to increasing the strength of the spring load-bearing crossbeam. The body of the spring load-bearing crossbeam is a long strip plate structure, and the protrusion is formed by stamping along the length direction of the long strip structure to a side perpendicular to the body. The protrusion is a long strip structure located in the middle of the body, so that the spring load-bearing crossbeam is symmetrically arranged in the upper and lower parts, so that it can be used for both left and right. In the actual installation process, there is no need to distinguish the left and right relationship, which improves the assembly efficiency.

[0022] Preferably, the strip-shaped protrusion includes a side wall and a top wall, and the side wall and the top wall have a non-smooth transition. The two spring hanging portions include a first notch respectively opened on the side wall on one side of the strip-shaped protrusion and the connected top wall, and a second notch opened on the side wall on the other side of the strip-shaped protrusion and the connected top wall.

[0023] In the above scheme, the first spring hanging portion includes a first notch opened on the upper side wall of the protrusion and the connected top wall, so that the first notch is suitable for hanging the spring when the first connecting structure is higher than the second connecting structure. Because the notch is opened on the upper side wall of the protrusion, the hook at the end of the spring is suitable for being inserted into the notch from top to bottom, and the hook is supported by the top wall; similarly, the second spring hanging portion includes a second notch opened on the lower side wall of the protrusion and the connected top wall, the first notch and the second notch are not connected, and are separated by the top wall, so that the second notch is suitable for hanging the spring when the second connecting structure is higher than the first connecting structure, and the hook at the end of the spring is suitable for being inserted from the second notch on the side wall of the protrusion from top to bottom, and the hook is supported by the top wall portion between the first notch and the second notch.

[0024] Preferably, the main body is further provided with a spring avoidance structure, which is configured so that after the spring is hung on the spring hanging portion, there is a gap between the spiral section and the main body.

[0025] In the above scheme, because the main body is located on both sides of the protruding part and is a planar structure, when the spring is hung on the spring load-bearing beam, the spring and the planar structure on both sides of the protruding part (i.e., the vertical surface) have a small inclination angle, which is easy to rub against the planar part, easily generate noise, and is not conducive to the stable hanging effect of the spring. Therefore, in the present invention, an avoidance structure is provided, which not only prevents the planar part from rubbing against the spring, but is also suitable for the spring to be stably hung on the spring load-bearing beam.

[0026] Preferably, the avoidance structure is two symmetrical recesses formed by local depressions on the upper and lower sides of a side of the body opposite to the spring, and when the spring is hung on the spring hanging part, a gap is left between the surface of the recess located on the lower side of the load-bearing beam.

[0027] Preferably, the two recesses are respectively located on the planar structures on the upper and lower sides of the protrusion on the main body, extending from the protrusion to the edge of the main body, the extension direction is perpendicular to the protrusion and the width of the recess gradually increases from the edge of the protrusion to the edge of the main body to prevent the spiral section of the spring from touching the main body.

[0028] Furthermore, the top wall of the protrusion has different heights, and the top wall where the first spring hanging part and the second spring hanging part are located is higher than the height of the adjacent top wall. Looking along the cross section of the spring load-bearing crossbeam, the ratio of the width of the protrusion: the width of the planar structure on the upper or lower side of the protrusion is 1:2 to 3:2; preferably, the ratio of the width of the protrusion: the width of the planar structure on the upper or lower side of the protrusion is 1:1. The inventor has proved in a large number of experiments that when the ratio of the width of the protrusion: the width of the planar structure on the upper or lower side of the protrusion is 1:2 to 3:2, the spring load-bearing crossbeam has a good load-bearing strength and meets the safety conditions.

[0029] Another object of the present invention is to provide a frame of a clothes processing device, the frame having the above-mentioned spring-loaded crossbeam.

[0030] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0031] 1. The spring load-bearing cross beam of the present invention comprises a long strip-shaped main body, a first connecting structure is arranged on the upper side of the main body, and a second connecting structure is arranged on the lower side of the main body. The main body is connected and fixed to a reinforcement member on the frame of the clothing processing device through the first connecting structure and / or the second connecting structure. Preferably, the first connecting structure and the second connecting structure are symmetrically arranged on the upper and lower sides of the main body. The spring load-bearing cross beam is universal on the left and right sides. In the actual assembly process, there is no need to distinguish the left and right positions of the spring load-bearing cross beam, and only the front and back sides of the load-bearing beam need to be distinguished, thereby saving the time for adjusting the position of the load-bearing beam during the installation process and improving work efficiency.

[0032] 2. In the present invention, a strip-shaped protrusion is formed by punching the middle surface of the main body along its length direction toward one side, and the two spring hanging parts include two notches symmetrically opened on the protrusion, and the first connection structure and the second connection structure are respectively arranged on the plane structure located on the upper side and the lower side of the protrusion on the main body. Preferably, the side wall and the top wall surface of the protrusion are formed with irregular structures: including a plurality of planes of different heights, each plane having a smooth or non-smooth transition. The protrusion is an irregular structure, which is conducive to increasing the strength of the spring load-bearing beam. The main body of the spring load-bearing beam is a long strip plate-like structure, and the protrusion is formed by punching the long strip structure toward one side perpendicular to the main body along the length direction of the long strip structure. The protrusion is a long strip structure located in the middle of the main body, thereby constituting the spring load-bearing beam to be symmetrically arranged as a whole from top to bottom, so that it can be used for both left and right. In the actual installation process, it is not necessary to distinguish the left and right relationship, thereby improving the assembly efficiency.

[0033] 3. In the present invention, the main body of the spring load-bearing crossbeam is also provided with an avoidance structure for avoiding the spring, so that after the spring is hung on the spring hanging part, there is a gap between the spiral section and the main body. Because the main body is located on both sides of the protruding part and is a planar structure, when the spring is hung on the spring load-bearing crossbeam, the spring and the planar structure on both sides of the protruding part (i.e., the vertical surface) have a small inclination angle, which is easy to rub against the planar part, easily generate noise, and is not conducive to the hanging stability effect of the spring. Therefore, in the present invention, an avoidance structure is provided, which not only prevents the planar part from rubbing against the spring, but also is suitable for the spring to be stably hung on the spring load-bearing crossbeam. The avoidance structure is formed by two symmetrical recesses formed by local depressions on the upper and lower sides of the side opposite to the spring on the main body, and when the spring is hung on the spring hanging part, there is a gap between the surface of the recess located on the lower side of the load-bearing beam. The two recesses are respectively located on the planar structures on the upper and lower sides of the protruding portion on the main body, extending from the protruding portion to the edge of the main body. The extension direction is perpendicular to the protruding portion and the width of the recess gradually increases from the edge of the protruding portion to the edge of the main body to prevent the spiral section of the spring from touching the main body.

[0051] Embodiment 1

[0052] See also Figure 1-Figure 5 As shown, this embodiment provides a spring-loaded crossbeam 2 for use in a clothing processing device. Figure 5 As shown, the clothing processing device includes a frame 1 and a clothing processing drum 5 arranged in the internal space of the frame, the clothing processing drum 5 is hung on a spring-loaded beam 2 on the frame 1 through a spring 4, the spring-loaded beam 2 includes a long strip-shaped body, a first connecting structure 21 is arranged on the upper side of the body, and a second connecting structure 22 is arranged on the lower side of the body, and the body is connected and fixed to the reinforcement on the frame 1 through the first connecting structure 21 and / or the second connecting structure 22.

[0053] In the above scheme, the main body can be connected and fixed to the reinforcement on the skeleton 1 through the first connecting structure 21 and / or the second connecting structure 22. When the main body is fixed to the reinforcement of the skeleton 1 through the first connecting structure 21 and the second connecting structure 22 at the same time, the fixing stability of the spring load-bearing beam 2 is improved.

[0054] Preferably, the first connection structure 21 includes two connection structures respectively located at both ends of the upper side of the main body, and the second connection structure 22 includes two connection structures respectively located at both ends of the lower side of the main body; wherein the first connection structure 21 and the second connection structure 22 can adopt the same connection structure or different connection structures.

[0055] Preferably, the first connection structure 21 and the second connection structure 22 are connection structures with the same structure.

[0056] Preferably, the two connection structures of the first connection structure 21 and the two connection structures of the second connection structure 22 are symmetrically arranged on the upper and lower sides of the main body.

[0057] In the above scheme, when the first connecting structure 21 and the second connecting structure 22 are symmetrical up and down, the spring load-bearing beam 2 can be used for both left and right. In the actual assembly process, there is no need to distinguish the left and right positions of the spring load-bearing beam 2, but only the front and back sides of the load-bearing beam need to be distinguished, thereby saving the time for adjusting the position of the load-bearing beam during the installation process and improving work efficiency.

[0058] Preferably, the first connection structure 21 includes through holes provided at both ends of the upper side of the body, and the upper side of the body is fixed to the reinforcement member on the frame 1 through the through holes by fasteners, or the first connection structure 21 includes contact portions of the reinforcement member on the frame 1 located at both ends of the upper side of the body, and the contact portions are welded and fixed to the corresponding reinforcement member;

[0059] And / or, the second connection structure 22 includes through holes arranged at the two end edges of the lower side of the main body, and the lower side of the main body is fixed to the reinforcement on the frame 1 through fasteners passing through the through holes, or the second connection structure 22 includes a contact portion of the reinforcement on the frame 1 located at the two end edges of the lower side of the main body, and the contact portion is welded and fixed to the corresponding reinforcement.

[0060] Preferably, a first spring hanging portion 23 is provided on the main body corresponding to the first connecting structure 21, and a second spring hanging portion 24 is provided on the main body corresponding to the second connecting structure 22. The first spring hanging portion 23 and the first connecting structure 21 are located on the same side of the main body, and the second spring hanging portion 24 and the second connecting structure 22 are located on the same side of the main body.

[0061] In the above scheme, when the spring load-bearing cross beam 2 is fixed to the reinforcement member on the frame 1 by the first connection structure 21, the first spring hanging portion 23 is suitable for hanging the spring 4, and when the spring load-bearing cross beam 2 is fixed to the reinforcement member on the frame 1 by the second connection structure 22, the second spring hanging portion 24 is suitable for hanging the spring 4;

[0062] Alternatively, when the first connection structure 21 and the second connection structure 22 of the spring load-bearing cross beam 2 are both fixed to the reinforcement on the frame 1, the spring 4 is hung by the spring hanging portion corresponding to the first or second connection structure at a higher position.

[0063] Preferably, the two spring hanging parts are symmetrically arranged on the main body, and are used to hang the spring 4 by the spring hanging part corresponding to the first connecting structure 21 / the second connecting structure 22 at a higher position after the spring load-bearing crossbeam 2 is fixed to the reinforcement member on the frame 1;

[0064] In the above scheme, by arranging the two spring hanging parts symmetrically up and down, the first spring hanging part 23 and the second spring hanging part 24 are respectively suitable for hanging the spring 4 by the first spring hanging part 23 when the first connecting structure 21 is higher than the second connecting structure 22, and hanging the spring 4 by the second spring hanging part 24 when the second connecting structure 22 is higher than the first connecting structure 21.

[0065] Preferably, the middle surface of the body along the length direction is punched to one side to form a strip-shaped protrusion 25, the two spring hanging parts include two notches symmetrically opened on the protrusion 25, and the first connection structure 21 and the second connection structure 22 are respectively arranged on the plane structure on the upper side and the plane structure on the lower side of the protrusion 25 on the body, see the reference 26 in the attached figure. Preferably, the side wall 27 and the top wall 28 of the protrusion 25 are formed with irregular structures: including multiple planes of different heights, each plane having a smooth or non-smooth transition.

[0066] In the above scheme, the protrusion 25 is an irregular structure, which is beneficial to increase the strength of the spring load-bearing cross beam 2. The body of the spring load-bearing cross beam 2 is a long strip plate structure, and the protrusion 25 is formed by stamping along the length direction of the long strip structure to the side perpendicular to the body. The protrusion 25 is a long strip structure located in the middle of the body, so that the spring load-bearing cross beam 2 is symmetrically arranged in the upper and lower parts, so that it can be used for both left and right. In the actual installation process, there is no need to distinguish the left and right relationship, which improves the assembly efficiency.

[0067] Preferably, the strip-shaped protrusion 25 includes a side wall 27 and a top wall 28, and the side wall 27 and the top wall 28 have a non-smooth transition. The two spring hanging portions include a first notch respectively opened on the side wall 27 on one side of the strip-shaped protrusion 25 and the connected top wall 28, and a second notch opened on the side wall on the other side of the strip-shaped protrusion 25 and the connected top wall 28.

[0068] In the above scheme, the first spring hanging portion 23 includes a first notch opened on the upper side wall of the protrusion 25 and the connected top wall 28, so that the first notch is suitable for hanging the spring 4 when the first connecting structure 21 is higher than the second connecting structure 22. Because the notch is opened on the upper side wall of the protrusion 25, the hook at the end of the spring 4 is suitable for inserting into the notch from top to bottom, and the hook is supported by the top wall 28; similarly, the second spring hanging portion 24 includes a second notch opened on the lower side wall of the protrusion 25 and the connected top wall 28. The first notch and the second notch are not connected and are separated by the top wall 28, so that the second notch is suitable for hanging the spring 4 when the second connecting structure 22 is higher than the first connecting structure 21. The hook at the end of the spring 4 is suitable for inserting from the second notch on the side wall of the protrusion 25 from top to bottom, and the hook is supported by the top wall 28 between the first notch and the second notch.

[0069] Preferably, the main body is further provided with an avoidance structure for avoiding the spring 4, so that after the spring 4 is hung on the spring hanging portion, there is a gap between the spiral section and the main body.

[0070] In the above scheme, because the main body is located on both sides of the protrusion 25 and is a planar structure 26, when the spring 4 is hung on the spring load-bearing beam, the spring 4 and the planar structure 26 on both sides of the protrusion 25 (i.e., the vertical surface) have a small inclination angle, which is easy to rub against the planar part, easily generate noise, and is not conducive to the stable hanging effect of the spring 4. Therefore, in the present invention, an avoidance structure is provided, which not only prevents the planar part from rubbing against the spring 4, but is also suitable for the spring 4 to be stably hung on the spring load-bearing beam.

[0071] Preferably, the avoidance structure is two symmetrical recesses 261 formed by local depressions on the upper and lower sides of the side of the main body opposite to the spring 4. When the spring 4 is hung on the spring hanging part, a gap is left between the surface of the recess 261 located on the lower side of the load-bearing beam.

[0072] Preferably, the two recesses 261 are respectively located on the planar structures 26 on the upper and lower sides of the protrusion 25 on the main body, extending from the protrusion to the edge of the main body, and the extension direction is perpendicular to the protrusion and the width of the recess 261 gradually increases from the edge of the protrusion to the edge of the main body to prevent the spiral section of the spring 4 from touching the main body.

[0073] Preferably, the two recesses 261 and the two spring hanging portions are all arranged on the same straight line perpendicular to the length direction of the main body, and the four are symmetrically arranged up and down and left and right.

[0074] Preferably, the reinforcement of the skeleton 1 of the clothing processing device includes four vertically arranged sheet metal parts 11, and the first connecting structure 21 located on the upper side of the protrusion 25 and the second connecting structure 22 located on the lower side of the body of the spring load-bearing beam 2 at both ends are respectively fixed to the two sheet metal parts 11 on one side of the skeleton 1, the left connecting structure of the first connecting structure 21 on the upper left side of the body and the left connecting structure of the second connecting structure 22 below are fixed to a sheet metal part on the skeleton 1, and the right connecting structure of the first connecting structure 21 on the upper right side of the body and the right connecting structure of the second connecting structure 22 below are fixed to another sheet metal part on the skeleton 1.

[0075] Furthermore, the top wall 28 of the protrusion has different heights, and the top wall 28 where the first spring hanging portion 23 and the second spring hanging portion 24 are located is higher than the height of the adjacent top wall 28. Looking along the cross section of the spring load-bearing crossbeam 2, the ratio of the width of the protrusion: the width of the planar structure 26 on the upper or lower side of the protrusion is 1:2 to 3:2; preferably, the ratio of the width of the protrusion: the width of the planar structure 26 on the upper or lower side of the protrusion is 1:1.
