Technical Field

[0001] The utility model relates to the technical field of washing tub structures, in particular to a reinforcement structure of a washing tub and a washing machine with the reinforcement structure. Background Art

[0002] The rear end of the plastic washing tub in existing drum washing machines suffers from poor strength. Two main solutions exist: One is to use a large-diameter aluminum bearing support to enhance its strength. However, due to its larger outer diameter, this increases its size, weight, and cost. The other is to use a conventional cast iron support. However, due to its limited size and strength, this product cannot support high-speed operation. Therefore, a new structure is needed to strengthen the plastic outer tub of a drum washing machine. Utility Model Content

[0026] Example 1

[0027] See also Figures 1 to 4 As shown, the utility model is a reinforcement structure of a washing tub, comprising a washing tub body 1 and a support base body 2 integrally injection-molded on the outer bottom of the rear end of the washing tub body 1; wherein, when the washing tub body 1 and the support base body 2 are integrally injection-molded, the concentricity between the two is set to be consistent, and the circumferential side wall of the support base body 2 is connected to the washing tub body 1 through a plurality of spaced-apart reinforcing ribs 11.

[0028] The reinforcement structure of the present invention is to injection mold the washing barrel body 1 and the support base body 2 as one piece to ensure the concentricity of the injection molding of the two, and the two are relatively fixed and can rotate together. In addition, the support base body 2 and the washing barrel body 1 are connected as an integral structure through a number of reinforcing ribs 11 arranged at intervals, which can ensure the connection strength of the integrally injection molded washing barrel body 1 and the support base body 2 to meet the higher speed requirements of the washing machine.

[0029] It should be understood that the washing barrel body 1 and the support base body 2 are integrally injection molded to improve the production efficiency and assembly quality between the two, and at the same time reduce the screw mechanical connection assembly process, so that the reinforcement structure of the present invention increases the strength of the washing barrel body 1 while improving its axial strength, preventing its deformation, thereby ensuring the uniformity of force on the washing barrel body 1.

[0030] In this embodiment, Figure 1 and Figure 2As shown, the outer bottom of the rear end of the washing barrel body 1 is provided with an annular rib ring 10, and the annular rib ring 10 is connected to the circumferential side wall of the support seat body 2 through a plurality of spaced reinforcing ribs 11 as an integral structure. When the washing barrel body 1 and the support seat body 2 are integrally injection-molded, the annular rib ring 10 and the support seat body 2 are fixedly connected by a plurality of spaced reinforcing ribs 11, thereby enhancing the radial and axial strength of the washing barrel body 1 and further ensuring the uniformity of the force on the washing barrel body 1.

[0031] In this embodiment, Figure 3 and Figure 4 As shown, a plurality of reinforcing convex ring portions 21 and reinforcing column portions 22 are evenly distributed on the circumferential side walls of the support seat body 2, and the reinforcing column portions 22 are spaced apart between adjacent reinforcing convex ring portions 21. The plurality of reinforcing convex ring portions 21 and reinforcing column portions 22 are provided to enhance the strength of the support seat body 2 itself, thereby strengthening the connection strength with the washing barrel body 1 which is integrally injection molded.

[0032] In this embodiment, Figure 3 and Figure 4 As shown, the outer side walls of the reinforcing convex ring portion 21 and the reinforcing column portion 22 are respectively connected to the annular rib ring 10 through a plurality of spaced reinforcing ribs 11 as an integral structure. The provided reinforcing convex ring portion 21 and the reinforcing column portion 22 facilitate increasing the connection contact area with the reinforcing ribs 11, especially the relationship between the reinforcing column portion 22 and the annular rib ring 10 through the reinforcing ribs 11, which can greatly enhance the connection strength between the washing barrel body 1 and the support base body 2.

[0033] It should be understood that the reinforcement columns 22 can be evenly distributed, or the reinforcement columns 22 can be increased or decreased according to the weak points of the outer bottom at the rear end of the washing tub 1.

[0034] In this embodiment, Figure 3 and Figure 4 As shown, a plurality of raised ribs 20 are evenly distributed on the circumferential side wall of the support seat body 2. The raised ribs 20 are spaced apart between adjacent reinforcing convex ring portions 21 and reinforcing column portions 22. The provided raised ribs 20 strengthen the strength of the support seat body 2 itself and facilitate positioning and integral injection molding with the washing barrel body 1.

[0035] In this embodiment, Figure 1 and Figure 2 As shown, the outer bottom of the rear end of the washing barrel body 1 is provided with a plurality of concentric annular rib rings 2 12, and the adjacent annular rib rings 2 12 are connected and fixed. The concentricity between the annular rib ring 2 12 and the annular rib ring 1 10 is set to be consistent, the two are connected and fixed, and the diameter of the annular rib ring 10 is smaller than the diameter of the annular rib ring 2 12. The multiple concentric annular rib rings 2 12 can enhance the self-injection molding strength of the outer bottom of the rear end of the washing barrel body 1.

[0036] Since the support base body 2 bears more pressure in this structure, in this embodiment, the support base body 2 is made of cast iron.

[0037] Example 2

[0038] Combine Figures 1 to 4 As shown, the present invention also provides a washing machine with a reinforced structure, in which the reinforcement structure of the above-mentioned embodiment 1 is arranged on the washing tub inside the washing machine; the washing machine in this embodiment distributes several reinforcing columns 22 on the outside of the cast iron support base 2, and the cast iron support base 2 with the reinforcing columns 22 is integrally injection-molded on the washing tub 1, and the reinforcing columns 22 are fixedly connected to the washing tub 1 through multiple reinforcing ribs 11 through the reinforcing columns; by adopting this technical solution, the axial strength of the washing tub 1 is increased while the strength thereof is increased to prevent deformation thereof, thereby ensuring uniform force on the washing tub 1; by adopting this technical solution, the service life and stability of the washing machine can be improved, and it has good practicality.

[0039] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
