Description

Technical Field

[0001] The utility model relates to the technical field of washing machine component structures, in particular to a novel pulsator outer barrel suspension structure. Background Art

[0002] Due to its convenience, the pulsator washing machine has become a commonly used household appliance. Among them, the outer barrel of the pulsator washing machine needs to be installed on the cabinet through a suspension structure. Since the weight of the washing machine barrel is supported by this part, the strength of the outer barrel suspension structure needs to be ensured.

[0003] In the prior art, a large number of reinforcing ribs are generally added to the suspension structure of the outer drum of a pulsator washing machine to enhance the support strength. The suspension structure composed of the reinforcing ribs makes the force-bearing surface distributed on the surface of each reinforcing rib. However, during the production process, each reinforcing rib may not be guaranteed to be on a spherical surface, which can easily cause unstable force on the outer drum suspension, thereby causing the suspension structure on the side with force offset to be easily damaged due to insufficient support strength, resulting in a high maintenance failure rate of the suspension structure of the outer drum of the pulsator washing machine, affecting the service life of the pulsator washing machine. Utility Model Content

[0004] The purpose of the utility model is to provide a novel impeller outer barrel suspension structure for solving the above technical problems.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A novel impeller outer barrel suspension structure comprises an outer barrel body, wherein a plurality of suspension devices are evenly distributed on the circumferential outer wall of the outer barrel body, the suspension devices are integrally cast with the outer barrel body, and each of the suspension devices is located at the same casting height as the outer barrel body.

[0007] As a further solution of the present invention: the number of castings of the suspension device is at least 3.

[0008] As a further solution of the present invention: the suspension device includes a retaining rib block part 1 and a retaining rib block part 2, the rear ends of the retaining rib block part 1 and the retaining rib block part 2 are closed and cast integrally with the outer wall of the outer barrel body, and the front ends of the retaining rib block part 1 and the retaining rib block part 2 are provided with gap holes, and the opening direction of the gap holes is consistent with the height direction of the outer barrel body.

[0011] As a further solution of the present invention: the width of the gap hole is 6-8 mm.

[0012] As a further solution of the present invention: the first retaining rib block portion and the second retaining rib block portion are respectively reinforced and connected to the outer barrel body through a plurality of reinforcing ribs.

[0013] Beneficial effects of the utility model:

[0014] (1) In the present application, a plurality of suspension devices are integrally cast on the outer circumferential wall of the outer barrel body. Specifically, the core pulling structure when the mold is ejected can be utilized to facilitate the control of the casting accuracy between the two, ensuring that each suspension device is located at the same casting height as the outer barrel body. When the outer barrel body is suspended on the box body, each suspension device is subjected to uniform force, avoiding the occurrence of support force deviation. The number of mold forming of the reinforcing ribs can be greatly reduced, thereby reducing the maintenance failure rate of the outer barrel suspension structure of the pulsator washing machine and contributing to the service life of the pulsator washing machine.

[0015] (2) During the use of the suspension device, a spherical support portion is formed between the first and second retaining rib blocks. When the spherical support portion is installed with the suspension assembly on the box, the suspension assembly on the box can be inserted into the suspension through hole through the clearance hole, so that the spherical support portion can increase the contact area with the suspension assembly on the box, thereby playing the role of dispersing the supporting force and ensuring the supporting strength of each suspension device;

[0016] (3) By setting anti-shrinkage holes on the front end outer walls of the rib block part 1 and the rib block part 2, the anti-shrinkage holes can prevent the material from generating bubbles and shrinkage holes during the cooling and shrinkage process during the casting process of the rib block part 1 and the rib block part 2, and can prevent the rib block part 1 and the rib block part 2 from generating shrinkage cavities during the cooling and molding process. The set anti-shrinkage holes can ensure the mechanical properties and appearance quality of the suspension device, thereby improving the reliability and service life of the suspension device.

[0028] Specifically, during the use of the suspension device 2, a spherical support portion 25 is formed between the retaining rib block portion 1 20 and the retaining rib block portion 21. When installed with the suspension component on the box, the suspension component on the box can pass through the gap hole 22 into the suspension through hole 26, so that the spherical support portion 25 can increase the contact area with the suspension component on the box, thereby playing a role in dispersing the supporting force and ensuring the supporting strength of each suspension device 2.
