[0039] Embodiment 1

[0040] See also Figure 1-Figure 5 , this embodiment provides an outer drum, which is the outer drum of a clothes processing device.

[0041] Specifically, the clothes processing device is a drum washing machine.

[0042] Specifically, see Figure 1 and Figure 2 The outer cylinder includes an outer cylinder body 1, and the outer cylinder body 1 includes a cylinder bottom 11 and a side wall 12 arranged circumferentially around the cylinder bottom 11. The cylinder bottom 11 and the side wall 12 are jointly arranged to form an inner cavity 13.

[0043] Generally speaking, the clothing processing device also includes an inner drum rotatably arranged in the inner cavity 13 of the outer drum body 1; in order to realize the rotation of the inner drum relative to the outer drum, it is generally necessary to install a motor on the outer surface of the drum bottom 11 of the outer drum body 1, and the drum bottom 11 is provided with a shaft sleeve. The output shaft of the motor passes through the shaft sleeve of the drum bottom 11 and extends into the inner cavity 13, and the inner drum is driven to rotate by the output shaft of the motor.

[0044] In the prior art, in order to achieve the positioning of the motor, it is generally necessary to install a motor positioning card on the shaft sleeve, and the motor positioning card can be engaged with the motor positioning groove on the motor to achieve the positioning of the motor.

[0045] However, installing the motor positioning card on the shaft sleeve causes the step of installing the motor positioning card to affect the assembly speed when assembling the drum washing machine.

[0046] To reduce the number of installation steps during the assembly of the laundry treatment device, see Figure 3-Figure 5 In this embodiment, the outer cylinder also includes a motor positioning structure 2.

[0047] The motor positioning structure 2 is integrally formed and arranged on the surface of the cylinder bottom 11 away from the inner cavity 13. The motor positioning structure 2 can position the motor installed on the outer cylinder.

[0048] The outer cylinder provided in this embodiment has a motor positioning structure 2 integrally formed on the surface of the cylinder bottom 11 facing away from the inner cavity 13, and the motor is positioned by the motor positioning structure 2; in the process of assembling the product, the step of installing the motor positioning card on the shaft sleeve in the prior art is omitted, thereby improving the assembly efficiency of the product.

[0049] Specifically, the motor positioning structure 2 is integrally formed by injection molding on the surface of the barrel bottom 11 away from the inner cavity 13. Such a configuration fully ensures the connection strength between the motor positioning structure 2 and the barrel bottom 11.

[0050] Specifically, in this embodiment, the motor positioning structure 2 includes a motor positioning member 21 integrally formed and arranged on the bottom of the cylinder 11, and the motor positioning member 21 is provided with an inner ring abutment surface 211, and the inner ring abutment surface 211 is configured to abut against the inner side ring surface of the motor positioning groove of the motor; and / or

[0051] The motor positioning member 21 is provided with an outer ring abutting surface 212 , and the outer ring abutting surface 212 is configured to abut against the outer ring surface of the motor positioning groove of the motor.

[0052] Preferably, in this embodiment, the motor positioning structure 2 includes a motor positioning part 21 integrally formed and arranged on the bottom of the cylinder 11, and the motor positioning part 21 is provided with an inner ring abutment surface 211 and an outer ring abutment surface 212, the inner ring abutment surface 211 is configured to abut against the inner ring surface of the motor positioning groove, and the outer ring abutment surface 212 is configured to abut against the outer ring surface of the motor positioning groove of the motor; such a setting fully ensures the stable positioning of the motor.

[0053] Preferably, in this embodiment, the motor positioning structure 2 includes a plurality of motor positioning members 21, and the plurality of motor positioning members 21 are arranged at equal intervals around the axis of the outer cylinder body 1. That is, in this embodiment, the motor positioning structure 2 is not an annular structure as a whole, and includes a plurality of motor positioning members 21 arranged at intervals along the circumference, and the outer annular surface of the motor positioning groove of the motor is positioned by a plurality of outer annular abutting surfaces 212 arranged at intervals along the circumference, and the inner annular surface of the motor positioning groove of the motor is positioned by a plurality of inner annular abutting surfaces 211 arranged at intervals along the circumference, which, on the one hand, ensures the stability of the motor positioning; on the other hand, compared with the annular motor positioning card in the prior art, the contact area between the plurality of motor positioning members 21 and the motor positioning groove is reduced, which makes it more convenient to fine-tune the motor after positioning, and quickly install the motor on the outer cylinder.

[0054] The gap between two adjacent motor positioning members 21 can reduce the contact area between the inner surface of the motor positioning groove and the motor positioning structure 2, making it easier to fine-tune the motor after the motor is initially installed in place.

[0055] More specifically, in this embodiment, the cylinder bottom 11 is provided with a shaft sleeve mounting hole 111 , and a plurality of motor positioning members 21 are arranged at intervals along the circumference of the shaft sleeve mounting hole 111 .

[0056] Preferably, a plurality of motor positioning members 21 are arranged at equal intervals along the circumference of the shaft sleeve mounting hole 111 .

[0057] In the clothes processing device, the sleeve is located at the sleeve mounting hole 111. In the actual manufacturing process, the sleeve is first cast, and then the outer cylinder is formed by injection molding, and the outer cylinder is integrally formed with the sleeve by injection molding.

[0058] Specifically, see Figure 3 and Figure 4 The motor positioning member 21 includes an outer supporting portion 213 and two inner supporting portions 214 .

[0059] An outer ring abutting surface 212 is disposed on the outer supporting portion 213 .

[0060] The two inner support portions 214 are respectively located on both sides of the outer support portion 213 . The inner support portion 214 is arranged relative to the outer support portion 213 and close to the axis of the outer cylinder body 1 . An outer ring abutting surface 212 is arranged on the inner support portion 214 .

[0061] It can be understood that, in this embodiment, all the outer ring abutting surfaces 212 are located on the same circumference; and all the inner ring abutting surfaces 211 are located on the same circumference.

[0062] Specifically, in this embodiment, the outer support portion 213 and the two inner support portions 214 are arranged in a roughly “J” shape.

[0063] Specifically, the outer support portion 213 and the inner support portion 214 are connected by a smooth transition portion. The provision of the smooth transition portion ensures that after the injection molding is completed, during the contraction process of the motor positioning member 21, the relative positions of the outer support portion 213 and the inner support portion 214 remain stable, thereby ensuring that the motor positioning member 21 stably positions the motor.

[0064] Preferably, along the axial direction of the outer cylinder body 1 , the maximum dimension of the outer support portion 213 and the maximum dimension of the inner support portion 214 are the same.

[0065] More specifically, along the axial direction of the outer cylinder body 1 , the maximum size of the outer support portion 213 and the maximum size of the inner support portion 214 are both the same as the depth of the motor positioning groove. This arrangement can fully ensure that the motor positioning member 21 can stably position the motor.

[0066] It should be noted that see Figure 3 During the processing and forming process, the surface of the inner support portion 214 facing the bottom of the motor positioning groove has a curved surface shape; the curved surface shape will not abut the bottom of the motor positioning groove. Similarly, the surface of the outer support portion 213 facing the bottom of the motor positioning groove has a curved surface shape; the curved surface shape will not abut the bottom of the motor positioning groove. The maximum size of the outer support portion 213 and the maximum size of the inner support portion 214 are both the same as the depth of the motor positioning groove. Such an arrangement can ensure that the surface of the outer support portion 213 facing the bottom of the motor positioning groove can stably abut against the bottom of the motor positioning groove, and the surface of the inner support portion 214 facing the bottom of the motor positioning groove can stably abut against the bottom of the motor positioning groove, so as to fully ensure the stable positioning of the motor by the motor positioning member 21.

[0067] Further preferably, in order to ensure the structural strength of the motor positioning member 21 , the motor positioning member 21 further includes a connecting portion 215 , and the connecting portion 215 is connected to both the outer supporting portion 213 and the inner supporting portion 214 .

[0068] Preferably, along the axial direction of the outer cylinder body 1 , the size of the connecting portion 215 is smaller than the size of the outer supporting portion 213 .

[0069] After installation, the outer support portion 213 will abut against the bottom of the motor positioning groove; and along the axial direction of the outer cylinder body 1, the size of the connecting portion 215 is smaller than the size of the outer support portion 213, so the connecting portion 215 will not abut against the bottom of the motor positioning groove, avoiding the connecting portion 215 interfering with the installation of the motor.

[0070] That is, the connection portion 215 is provided to ensure the structural strength of the motor positioning member 21 on the one hand, and to prevent the connection portion 215 from interfering with the installation of the motor on the other hand.

[0071] At the same time, the connecting portion 215 can also ensure that after the outer cylinder is injection molded, during the contraction of the motor positioning member 21, the relative positions of the outer support portion 213 and the inner support portion 214 remain stable, thereby ensuring that the motor positioning member 21 stably positions the motor.
