When the technical solutions between embodiments can be combined, they are all within the protection scope required by the present invention.

[0029] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0030] As Figure 1 and Figure 2 shown, a washing machine includes: an outer tub 200; an inner liner 100, the outer tub 200 is disposed inside the inner liner 100, and the outer tub 200 is connected to the inner liner 100; the inner liner 100 includes: an upper opening 121 of the inner liner, the upper opening 121 of the inner liner is communicated with the outer tub 200; a mounting portion, at least one is disposed on the outer side of the peripheral wall of the inner liner 100 for mounting at least a circuit board, a motor or a water pump.

[0031] For a small washing machine, in order to save internal space as much as possible, a sleeved inner liner 100 is provided outside the outer tub 200. Circuit boards, motors, water pumps, etc. are installed on the outer surface of the barrel wall of the inner liner 100. In addition, grooves can be provided to accommodate cables, etc. The outer tub 200 is connected to the inner liner 100 to form the internal structure of the washing machine. Compared with the existing ordinary large washing machines, there is no separate installation space for components, circuit boards, etc. inside the washing machine. The internal space of the washing machine is saved, and the miniaturization of the washing machine is realized.

[0032] Specifically, as Figure 2 shown, the installation part includes a stepped first installation part 111, a second installation part 120 provided with a support frame, or a third installation part 130 provided with an opening on the barrel wall, or a combined structure of at least two of the first installation part 111, the second installation part 112, and the third installation part 113.

[0033] The installation part has different shapes according to the shape, use, connection method, etc. of the installed components or circuit boards, etc. For example, the stepped first installation part 111 can install a water pump, etc. on the step, and through holes are provided on the barrel wall of the inner liner 100 so as to connect the water pump and the outer tub through a hose. The second installation part 112 provided with a support frame supports the component through the support, for example, fixes the circuit board on the support. The third installation part 113 provided with an opening can install a component with a housing. For example, a softener adding box can be installed on the housing of the washing machine, and the softener adding box with a certain thickness can be arranged through the opening-shaped third installation part 113. The above three forms of installation parts can be set separately or in combination of two or more. For example, a second installation part 112 with a support is provided on the stepped first installation part 111. When the water pump is fixed on the step, the water pump can also be supported by the support to avoid the water pump shaking, generating noise, and exerting force on the inner liner 100 and damaging the water pump when the washing machine is working. In addition to the above three forms of installation parts, other shaped installation parts can also be set according to actual needs. For example, a groove-type installation part can be set, and board-shaped components such as circuit boards can be inserted into the groove, which is convenient for installation, as well as socket-type, etc. Details are not described herein.

[0034] Specifically, a clamping assembly (not shown in the figure) is provided on the support frame of the second installation part 112.

[0035] By setting a clamping assembly on the support frame, after the component is installed in the second installation part 112, the component can be clamped by the clamping assembly to further fix the component.

[0036] Specifically, the inner liner cylinder 100 further includes an inner liner cylinder body 110 and an upper end plate 120 of the inner liner cylinder. The upper end plate 120 of the inner liner cylinder is connected to one end of the inner liner cylinder body 110, and the upper opening 121 of the inner liner cylinder is provided on the upper end plate 120 of the inner liner cylinder.

[0037] Specifically, as Figure 1 and Figure 2 shown, an 8-shaped through hole 122 for connecting the outer cylinder is provided on the upper end plate 120 of the inner liner cylinder, and the outer cylinder is connected to the 8-shaped through hole 122 through a spring suspension rod 300.

[0038] The installation part is arranged on the inner liner cylinder body 110 of the inner liner cylinder 100. The upper end plate 120 of the inner liner cylinder is arranged at one end of the inner liner cylinder body 110, and the 8-shaped through hole 122 is arranged on the upper end plate 120 of the inner liner cylinder. The outer cylinder 200 can be hoisted on the 8-shaped through hole 122 through the spring suspension rod 300. When the washing machine is working, the outer cylinder 200 can swing in the circumferential direction and vibrate in the up and down direction under the action of the spring of the spring suspension rod 300, so as to offset the vibration of the outer cylinder 200 during operation. Specifically, the 8-shaped through hole 122 is formed by the cross-connection of two through holes. One end of the spring suspension rod 300 connected to the 8-shaped through hole 122 is provided with an end cap. The diameter of the end cap is smaller than the diameter of one through hole in the 8-shaped through hole 133 and larger than the diameter of the other through hole. Moreover, the smallest through hole is in a shape concave towards the outer cylinder 200. During installation, the end cap of the spring suspension rod 300 passes through the large through hole and then moves towards the small through hole. After releasing the hand, the end cap is clamped in the pit of the small through hole.

[0039] Specifically, a buffer member (not shown in the figure) is provided on the surface of the cylinder wall of the inner liner cylinder 100 opposite to the outer cylinder 200.

[0040] The outer cylinder 200 will shake circumferentially during operation. In order to reduce the impact force generated by the collision between the outer cylinder 200 and the cylinder wall of the inner liner cylinder 100, a buffer member is provided on the side wall surface of the inner liner cylinder 100 relative to the outer cylinder 200. The buffer member can adopt elastic plate-shaped members such as sponge and rubber pad.

[0041] Specifically, as Figure 3 and Figure 4 shown, the washing machine further includes: a housing 400. The inner liner cylinder 100 is connected to the housing 400 inside the housing 400. An upper opening 421 of the housing is provided at the upper end of the housing 400, and the upper opening 421 of the housing is communicated with the upper opening 121 of the inner liner cylinder and the outer cylinder 200.

[0042] By arranging the inner liner cylinder 100 between the housing 400 and the outer cylinder 200, and installing various components, circuit boards, etc. on the inner liner cylinder 100, the internal space of the washing machine is saved and the volume of the washing machine is reduced. Because there are various installation parts on the outer surface of the inner liner cylinder body 110 of the inner liner cylinder 100, which affects the appearance beauty of the inner liner cylinder 100. Therefore, by sleeving the housing 400 on the outside of the inner liner cylinder 100, the appearance of the washing machine is improved. The outer cylinder 200 is hoisted inside the inner liner cylinder 100 through the spring suspension rods 300. During operation, the vibration generated by the outer cylinder 200 is transmitted to the inner liner cylinder 100, and due to the action of the spring suspension rods 300, the vibration is offset, and there is basically no vibration on the housing 400. Therefore, arranging the inner liner cylinder 100 between the housing 400 and the outer cylinder 200 can also play a role in reducing the external vibration of the washing machine.

[0043] Specifically, as Figure 4 and Figure 5 shown, the housing 400 includes: a housing body 410; a housing upper end plate 420, connected to the housing body 410, and a housing upper opening 421 is provided on the housing upper end plate 420; a housing lower end plate 430, connected to the housing body 410 opposite to the housing upper end plate 420.

[0044] By blocking both ends of the housing body 410 through the housing upper end plate 420 and the housing lower end plate 430, the housing 400 forms a closed housing, making the appearance of the washing machine neat. Only a housing upper opening 421 communicating with the upper opening 121 of the inner liner cylinder and the barrel mouth of the outer cylinder 200 is provided on the housing upper end plate 420, so as to be able to put clothes into the outer cylinder 200.

[0045] Specifically, the upper end plate 120 of the inner liner cylinder is connected to the housing upper end plate 420.

[0046] By connecting the upper end plate 120 of the inner liner cylinder to the housing upper end plate 420, the inner liner cylinder 100 is fixed to the housing 400.

[0047] Specifically, as Figure 5 and Figure 6 shown, the inner liner cylinder 100 further includes: an inner liner cylinder bracket 130', connected to the inner liner cylinder body 110' opposite to the upper end plate 120 of the inner liner cylinder; the inner liner cylinder bracket 130' is connected to the housing lower end plate 430.

[0048] As another implementation manner, according to actual needs, the height of the inner liner cylinder body 110 of the inner liner cylinder 100 does not need to be the same as that of the housing 400, and can even be less than the height of the outer cylinder 200, saving the material of the inner liner cylinder 100 and reducing the material cost.

[0049] As another embodiment of fixing the inner liner 100, when the height of the inner liner 100 is smaller than the outer tube 200 and the shell 400, an inner liner bracket 130' can be provided at the lower part of the inner liner 100, and fixed to the lower end plate 430 of the shell through the inner liner bracket 130'.

[0050] The above two fixing methods of the inner liner 100 and the shell 400 can be used in combination, that is, the inner liner upper end plate 120 of the inner liner 100 is fixed to the shell upper end plate 420, and at the same time, the inner liner bracket 130' is fixed to the shell lower end plate 430. In this installation method, the inner liner bracket 130' and the shell lower end plate 430 can be connected by springs instead of bolts, and the shell lower end plate 430 is then fixed to the shell body 410 by bolts. In this way, the vibration caused by the shaking of the outer cylinder 200 can be further eliminated.

[0051] Those skilled in the art will readily appreciate other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art that are not disclosed in this disclosure.
