[0003] In the existing washing machines, between the dewatering barrel body and the balance ring, and between the dewatering barrel body and the dewatering barrel bottom, in order to prevent rotational displacement during the washing process and affect the washing effect, a screw fixation method is generally used to prevent the occurrence of rotational displacement. However, this fixation method requires multiple screws, and at least two operators and at least two operating stations and workbenches or tooling are required for operation, which will result in high material costs, complex operations, time-consuming and laborious. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an inner barrel of a washing machine and a washing machine, so as to solve the problems of high cost and troublesome operation caused by screw fixation between the dewatering barrel body and the balance ring, and between the dewatering barrel body and the dewatering barrel bottom in the existing washing machines.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1:

[0031] As Figures 1-6 shown, a washing machine inner barrel includes a barrel body 1, barrel body accessories, and a ring rib 4 extending radially outwardly provided on the outer circumference of the connection between the barrel body accessories and the barrel body 1.

[0032] In this embodiment, the barrel body accessories include at least one of a balance ring 2 and a bottom of barrel 3. The connection between the barrel body 1 and the barrel body accessories is roller riveted to the barrel body accessories and wraps the ring rib 4. It can be understood that the barrel body of the washing machine inner barrel is a metal part, and certain deformation can be generated through rolling. Therefore, the barrel body can be connected to the above barrel body accessories by roller riveting. As Figure 2 and Figure 3 shown, when the barrel body accessory is a balance ring 2, a ring rib 4 is provided on the outer circumference of the lower end of the balance ring 2, and the upper end of the barrel body 1 is roller riveted to the lower end of the balance ring 2 and wraps the ring rib on the balance ring.

[0033] In this embodiment, the connection between the barrel body 1 and the barrel body accessories is roller riveted to the barrel body accessories and wraps the ring rib 4, replacing the original connection method of fixing the barrel body accessories and the barrel body 1 with screws. The roller riveting connection between the barrel body 1 and the barrel body accessories enables the barrel body 1 part to not need to reserve screw holes, saving costs, and the installation structure is also shorter than the existing installation dimensions; at the same time, due to the existence of the ring rib, the relative movement of the barrel body 1 and the barrel body accessories in the axial direction of the barrel body 1 is restricted, and a certain restrictive effect is provided on the relative movement of the barrel body 1 and the barrel body accessories in the circumferential direction of the barrel body 1.

[0034] As an optional technical solution of this embodiment, a flange 6 is provided on the annular rib 4, and the flange 6 on the annular rib 4 is wrapped by a roller riveting at the connection between the barrel body 1 and the barrel body accessory, so that the limiting effect on the relative movement of the barrel body 1 and the barrel body accessory in the axial and circumferential directions of the barrel body can be further strengthened. Optionally, in order to prevent the barrel body 1 from separating from the barrel body accessory, the flange 6 is formed by the annular rib 4 extending in a direction away from the barrel body 1, such as the flange 6 and the annular rib 4 are integrally formed, and the flange 6 extends radially from the annular rib 4 in a direction away from the barrel body 1.

[0035] For example Figure 4 and Figure 5 The barrel body accessory is a barrel bottom 3, and an annular rib 4 is arranged on the outer periphery of the upper end of the barrel bottom 3. A flange 6 is integrally formed on the outer peripheral edge of the annular rib 4, and the flange 6 extends from the annular rib 4 to a direction away from the barrel body 1, that is, downward as shown in the figure.

[0036] In this embodiment, in order to further strengthen the limiting effect on the relative movement of the barrel body 1 and the barrel body accessories in the circumferential direction of the barrel body 1, a limiting protrusion 5 can be further provided on the annular rib 4, and the limiting protrusion 5 is roller-riveted and attached at the connection between the barrel body 1 and the barrel body accessories.

[0037] In the absence of the limiting protrusion 5, the limiting force of the relative movement of the barrel body 1 and the barrel body accessories in the circumferential direction of the barrel body 1 only depends on the friction between the barrel body 1 and the barrel body accessories, and the barrel body 1 and the barrel body accessories are prone to relative movement. Figure 7 and Figure 8 Due to the existence of the limiting protrusion 5, when the barrel body 1 is roller-riveted to wrap the annular rib 4, the limiting protrusion will produce a certain deformation corresponding to the limiting protrusion, thereby causing the limiting protrusion 5 to limit the relative movement of the barrel body 1 and the barrel body accessories in the circumferential direction of the barrel body 1.

[0038] It can be understood that, in addition to the above-mentioned function of strengthening the limiting effect, the above-mentioned limiting protrusion 5 can also enhance the structural strength of the annular rib and play the role of a reinforcing rib.

[0039] As an optional implementation in this embodiment, the limiting protrusion 5 can be arranged on the surface of the annular rib 4 axially away from the barrel body 1.

[0040] In this embodiment, the balancing ring 2 may include an upper balancing ring 21 and a lower balancing ring 22. The lower balancing ring 22 is provided with the above-mentioned annular ribs 4. The barrel body 1 is tightly surrounded by the annular ribs 4 and the limiting protrusions 5 on the lower balancing ring 22 after roll riveting.

[0041] In actual products, such as Figure 4 and Figure 5, the annular rib 4 provided on the bottom 3 of this embodiment can be formed at the end face where the bottom 3 is connected to the barrel body 1, and the inner diameter of the annular rib 4 provided on the bottom 3 is smaller than the outer diameter of the barrel body 1. With such a setting, the annular rib 4 on the bottom 3 forms an axial support surface for the barrel body 1, that is, as Figure 5 shown, the upper surface of the annular rib 4 serves as the axial support surface of the barrel body 1..

[0042] As an alternative implementation, a flanging 6 can be provided only on the annular rib 4 on the bottom 3, and the barrel body 1 is roll-riveted and wrapped around the flanging 6 on the annular rib 4 at the connection with the bottom 3. The extending direction of the flanging 6 on the annular rib 4 on the bottom 3 is the same as the protruding direction of the limiting protrusion 5; at this time, no flanging needs to be provided on the balance ring, and only the above-mentioned annular rib 4 and limiting protrusion 5 are provided.

[0043] And as another alternative implementation, in addition to providing a flanging 6 and a limiting protrusion 5 on the annular rib 4 on the bottom 3, a flanging 6 and a limiting protrusion 5 are also provided on the annular rib 4 of the balance ring 2.

[0044] Embodiment 2:

[0045] This embodiment provides a washing machine, including the washing machine inner barrel described in any implementation of the foregoing embodiment.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
