The connecting beam 23 according to an embodiment of the present invention is described below with reference to fig. 1 to 39.

As shown in fig. 11 to 17, the connection beam 23 according to one embodiment of the present invention includes: the connection beam body 231 is adapted to be fixed to a bearing structure of the laundry treating apparatus 100, for example, to a vertical beam, or to front and rear beams of the laundry treating apparatus 100, and the connection beam body 231 has a support slope 2311, the support slope 2311 being a surface extending obliquely with respect to a vertical or horizontal plane, and a support seat 232 provided on the support slope 2311, the support seat 232 being for mounting a vibration damping device such as a vibration damping lever.

That is, a vibration damping device, such as a vibration damping rod, one end of which is connected to the tub of the laundry treating apparatus 100 and the other end of which is fixed to the support base 232, such as when the connecting beam 23 of the present embodiment is used for a laundry treating apparatus having a first laundry treating module and a second laundry treating module, the connecting beam 23 may be connected to a vertical beam of a frame of the laundry treating apparatus, the vibration damping device of the first laundry treating module located at the upper side, such as the vibration damping rod, may be directly supported on the support slope 2311, the support slope 2311 is inclined toward the first laundry treating module, so that the support slope 2311 may be approximately perpendicular to the support bar, thereby reducing a shearing force of the support rod to the support beam 23; for the supporting seat 232 is installed on the vertical supporting surface, the supporting seat 232 is supported on the inclined surface, so that tangential force of the damping rod of the washing bucket on the connecting beam body 231 can be reduced, the supporting seat 232 is prevented from sliding relative to the connecting beam body 231 to be disconnected, the connecting beam body 231 can also play a supporting role in supporting the damping rod of the washing bucket, and the stability of the structure is further improved.

However, if the support base 232 is directly mounted on the horizontal support surface, the size of the connection beam body 231 in the horizontal direction needs to be further increased, thereby occupying a larger mounting space on the laundry treating apparatus 100, and increasing the size of the connection beam body 231 also results in an increase in cost, so that the support base 232 is disposed on the support inclined surface 2311 according to the embodiment of the present invention, and thus, the structure of the support inclined surface 2311 does not increase the size of the mounting beam body 251, thereby avoiding an increase in cost, and facilitating the mounting of the mounting beam body 251 on the laundry treating apparatus 100, compared to the case of directly mounting the support base 232 on the horizontal support surface.

According to the connecting beam 23 of the embodiment of the invention, the supporting inclined plane 2311 is arranged on the connecting beam body 231, so that the supporting seat 232 for installing the vibration reduction rod can be obliquely supported on the connecting beam body 231, the supporting inclined plane 2311 can enable the stress of the connecting beam body 231 to be more reasonable, the connecting beam body 231 can also play a role in supporting the supporting seat 232, excessive installation space is not occupied, and the stability and reliability of the connecting beam 23 are improved.

As shown in fig. 15, according to an embodiment of the present invention, the support slope 2311 is located at the inner side of the connection beam body 231, i.e., the support slope 2311 is located at one side of the connection beam body 231 near the center of the laundry treating apparatus 100, and the support slope 2311 gradually extends obliquely toward one side near the center of the laundry treating apparatus 100 in a top-down direction, thereby enabling the support base 232 to be supported at the inner side of the connection beam body 231 (i.e., one side near the center of the laundry treating apparatus 100), the vibration damping device such as a vibration damping rod can be directly supported at the inner side of the connection beam body 231 when the vibration damping rod is installed, the installation is convenient, and the support base 232 has a good supporting effect on the vibration damping rod.

The inventor has verified through experimental analysis that when the included angle between the supporting inclined plane 2311 and the vertical plane is 20 ° -35 °, the supporting effect of the supporting inclined plane 2311 on the supporting seat 232 and the vibration-damping rod is best, preferably, the included angle between the supporting inclined plane 2311 and the vertical plane is 25 °, 27 °, 30 °, on the basis of ensuring structural stability, the thickness (distance in the left-right direction as shown in fig. 15) of the connecting beam body 231 is shortened, and the space occupied during installation thereof is reduced.

As shown in fig. 11 and 15, according to an embodiment of the present invention, at least a portion of the connection beam body 231 is recessed toward the inside of the connection beam body 231 to form a beam protrusion 2312 at the inside surface of the connection beam body 231 and a beam recess 2313 at the outside surface of the connection beam body 231, thereby improving the strength of the connection beam body 231 without increasing the size of the connection beam body 231 and also facilitating the assembly of the damper rod.

As shown in fig. 15, in some examples, the beam protrusion 2312 extends in a length direction of the connection beam body 231, that is, the length of the beam protrusion 2312 is increased, thereby increasing a position where the support base 232 can be mounted, so that the vibration-damping lever of the tub is fixed at an arbitrary position where the beam body 251 is mounted.

As shown in fig. 15, in some examples, at least a portion of the beam convex portion 2312 is recessed toward the outside of the connection beam body 231 to form a reinforcing concave portion 2314 at the inside surface of the connection beam 23 and a reinforcing convex portion 2413 at the outside surface of the connection beam 23, and the reinforcing concave portion 2314 may be formed by punching and manufacturing at the beam convex portion 2312, which may improve structural strength, simplify and facilitate manufacturing process, and improve feasibility and versatility of the product.

As shown in fig. 15, in some examples, the reinforcing concave portions 2314 include a plurality of reinforcing concave portions 2314 that are arranged at intervals along the length direction of the connecting beam body 231, and by providing the plurality of reinforcing concave portions 2314, the structural strength of the connecting beam body 231 in the length direction thereof is ensured to be uniform, thereby improving the overall structural strength of the connecting beam 23.

As shown in fig. 15, in some examples, the overall structural strength near the reinforcing recess 2314 is relatively high, and thus the support base 232 is disposed above the reinforcing recess 2314 to further improve the stability and reliability of the installation of the support base 232.

As shown in fig. 15, in some examples, the beam convex portion 2312 has a top wall 23121 and side walls 23122 located at both sides of the top wall 23121, wherein the top wall 23121 of the beam convex portion 2312 may be a vertical surface, one side wall 23122 of the beam convex portion 2312 is located above the top wall 23121 of the beam convex portion 2312, one side wall 23122 of the beam convex portion 2312 is located below the top wall 23121 of the beam convex portion 2312, the top wall 23121 and the side walls 23122 of the beam convex portion 2312 respectively extend in a length direction (front-rear direction as shown in fig. 15) connecting the beam body 231, a supporting slope 2311 is formed on a surface of the side wall 23122 of the beam convex portion 2312 located above the top wall 23121 thereof, the supporting slope 2311 is gradually and inwardly inclined in a top-down direction, and the supporting seat 232 is supported at the top inner side of the beam convex portion 2312, facilitating installation of the vibration damping rod, and improving stability after installation.
