Problems solved by technology

[0004] Although the drum provided by the prior art guarantees the structural strength and rigidity of the drum to a certain extent, since the operation of the washing machine depends on the high-speed rotation of the drum, once the drum bursts during high-speed operation, the hoop and the drum body will The rigid contact of the hoop may cause the hoop to be difficult to resist the impact of the burst and burst together with the drum, thereby causing serious damage to the washing machine, seriously damaging the user's property, and even affecting the user's life safety

Embodiment 1

[0035] figure 1 Schematic diagram of the structure of the cylinder hoop 2 provided by the embodiment of the present invention, figure 2 for figure 1 Partial enlarged view of I in the center, such as figure 1 and 2 As shown, this embodiment provides a cylinder hoop 2, which includes a sheet-shaped cylinder hoop body 21. The cylinder hoop body is in a ring shape, and the annular outer surface of the cylinder hoop body 21 is stamped inwardly to form a protrusion 22. The upper end surface is flush with the upper end surface of the cylinder hoop body 21 , and the lower end surface of the protrusion 22 is flush with the lower end surface of the cylinder hoop body 21 . And there are multiple protrusions 22 , and the plurality of protrusions 22 are arranged at intervals along the circumferential direction of the tube hoop 2 .

[0036] The cylinder collar 2 provided in this embodiment forms a protrusion 22 by recessing the cylinder collar body 21 inwardly. The outer surface of th...

Embodiment 2

[0048] Figure 4 The structure schematic diagram of the drum provided for the embodiment of the present invention, as Figure 4 As shown, this embodiment provides a drum, including a drum body 1, a front end cover 3 and a rear end cover 4, one end of the drum body 1 is connected to the front end cover 3, and the other end of the drum body 1 is connected to the rear end cover 4, the cylinder The outer surface of the hoop body 21 is sheathed with the hoop 2 described in the first embodiment, and the protrusion 22 in the hoop 2 is in contact with the outer surface of the drum body 1 .

[0049] By sheathing the above-mentioned hoop 2 on the outer surface of the drum body 1 , the strength and rigidity of the hoop body 21 can be increased, and the impact resistance of the hoop body 21 can also be improved. When the drum body 1 bursts and other phenomena, the structure of the cylinder hoop 2 makes the cylinder hoop 2 elastically contact with the drum body 1, which can absorb the imp...

Abstract

The invention belongs to the technical field of washing machines and particularly discloses a drum hoop, a drum and a washing machine. The drum hoop comprises a sheet drum hoop body in a ring shape, the ring outer surface of the drum hoop body is inwardly recessed to form a plurality of projections at intervals along the periphery of the drum hoop body, upper end faces of the projections are flushwith the upper end face of the drum hoop body, and lower end faces of the projections are flush with the lower end face of the drum hoop. The drum comprises a drum body and the drum hoop, and the drum hoop sleeves the outer surface of the drum body and contacts with the outer surface of the drum. The washing machine comprises the drum. The drum hoop, the drum and the washing machine has advantages that structural strength of the drum can be improved, impact resistance of the drum is improved, and safety and reliability of the drum and the washing machine are improved.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a drum hoop, a drum and a washing machine. Background technique [0002] With the improvement of people's living standards at any time, washing machines have gradually become one of the necessary household appliances for family life. Existing washing machines are generally divided into drum washing machines and pulsator washing machines. The drum washing machine uses a motor to drive the drum to rotate forward and backward at high speed, so that the clothes in the drum are continuously lifted and dropped, so as to achieve the effect of beating and washing the clothes. [0003] An industrial washing machine disclosed in the prior art has a drum structure mainly composed of drum mesh, several reinforcing ribs, front and rear end caps and other structures welded into a drum body, and the front, middle and rear three Parts are respectively provided with hoops, which are use...
