[0047] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0048] The present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0049] like Figure 1-10 As shown, an embodiment of the present application provides a washing machine, which may include an outer tub 11, an inner tub 12 installed inside the outer tub 11, a first pulsator 13 arranged on the inner tub 12, a sleeve tub 14 that can be detachably installed inside the inner tub 12, and a second pulsator 15 arranged in the sleeve tub 14. The outer tub 11 is used in conjunction with the inner tub 12 to supply water to the inner tub 12. The first pulsator 13 is generally arranged at the bottom of the inner tub 12, and can rotate relative to the inner tub 12 to drive the water and clothes in the inner tub 12 to move. The top of the sleeve tub 14 can be installed with the top of the inner tub 12, and the sleeve tub 14 can be stationary relative to the inner tub 12, so that the driving force received by the inner tub 12 can be transmitted to the sleeve tub 14, and the second pulsator 15 can be arranged at the bottom of the sleeve tub 14, and can rotate relative to the sleeve tub 14 to drive the water and clothes in the sleeve tub 14 to move.

[0050] The first pulsator 13 can be connected to the second pulsator 15 by transmission, so as to drive the second pulsator 15 to rotate. That is, when the first pulsator 13 rotates relative to the inner tub 12, the first pulsator 13 can drive the second pulsator 15 to rotate relative to the outer tub 14. Specifically, the first pulsator 13 can be connected to the second pulsator 15 by transmission shaft.

[0051] When the above-mentioned washing machine is working, if the amount of laundry is large, it is not necessary to put the outer barrel 14 into the inner barrel 12, and the clothes can be put into the inner barrel 12 for washing. When the amount of laundry is small, the outer barrel 14 can be put into the inner barrel 12, and then the clothes can be put into the outer barrel 14. After the washing machine is started, the first impeller 13 drives the second impeller 15 to rotate under the driving action of the driving part of the washing machine, thereby realizing the washing operation. Of course, in addition to using the above-mentioned outer barrel 14 when the amount of laundry is small, the outer barrel 14 can also be used in other cases as long as it can meet the washing requirements.

[0052] As can be seen from the above content, the washing machine provided in the embodiment of the present application can put the outer barrel 14 in the inner barrel 12, and the capacity of the outer barrel 14 can be set to be relatively small. Therefore, when the washing capacity is not large, the outer barrel 14 can be put into the inner barrel 12, and only water can be put into the outer barrel 14 for washing. When the washing capacity is large, the outer barrel 14 can be removed, and normal washing operations can be performed through the outer barrel 11 and the inner barrel 12. It can be seen that this washing machine can control the water consumption of the washing machine according to actual conditions, so that the economy of the washing machine is improved.

[0053] In one embodiment, the washing machine may further include a key connection structure, through which the first pulsator 13 is transmission-connected with the second pulsator 15. The key connection structure may specifically include a key tooth portion 16 disposed on the first pulsator 13 and a key sleeve 17 disposed on the barrel 14, and the key sleeve 17 can mesh with the key tooth portion 16. Specifically, the key tooth portion 16 has protruding teeth, and the key sleeve 17 has a groove that matches the teeth. When the key tooth portion 16 matches the key sleeve 17, the teeth on the key tooth portion 16 match the grooves on the key sleeve 17, so that power can be transmitted from the key tooth portion 16 to the key sleeve 17, thereby realizing power transmission between the first pulsator 13 and the second pulsator 15. This key connection structure has higher structural strength and transmission efficiency, and is easy to install. In addition, the key tooth portion 16 has little effect on the appearance of the first pulsator 13, nor does it affect the normal operation of the first pulsator 13; the key tooth portion 16 and the key sleeve 17 have sufficient assembly depth in the axial direction of the barrel 14 to prevent the two from being separated.

[0054] In order to facilitate the installation of the sleeve barrel, the washing machine provided in the embodiment of the present application may further include a balance ring 18, which is installed on the top of the inner barrel 12, and the top of the sleeve barrel 14 is positioned and matched with the balance ring 18 in the peripheral direction of the sleeve barrel 14. That is, the movement of the sleeve barrel 14 relative to the inner barrel 12 in its peripheral direction will be restricted. When the washing machine is in the washing state, the inner barrel 12 can be stationary relative to the outer barrel 11, and the sleeve barrel 14 is also stationary relative to the inner barrel 12; when the washing machine is in the spin-drying state, the inner barrel 12 can rotate relative to the outer barrel 11, and the sleeve barrel 14 will rotate driven by the inner barrel 12.

[0055] The balance ring 18 can bear the weight of the tub 14, water and clothes, and prevent the weight of the tub 14, water and clothes from acting on the first pulsator 13 or the transmission structure between the first pulsator 13 and the second pulsator 15, thereby preventing the first pulsator 13 or the transmission structure from being damaged. At the same time, the balance ring 18 can also prevent the tub 14 from tilting and prevent the balance ring 18 from interfering with the first pulsator 13.

[0056] Furthermore, a positioning protrusion is provided on one of the sleeve barrel 14 and the balance ring 18, and a positioning groove is provided on the other, and the positioning protrusion can be positioned and matched with the positioning groove, so as to achieve the purpose of positioning and matching between the sleeve barrel 14 and the inner barrel 12 in its peripheral direction. Optionally, the positioning protrusion can be provided on the sleeve barrel 14, and the positioning groove can be provided on the balance ring 18, or the positioning protrusion can be provided on the balance ring 18, and the positioning groove can be provided on the sleeve barrel 14. For example, Figure 3 As shown, a positioning protrusion 140 is provided on the sleeve barrel 14, and a positioning groove 180 is provided on the balance ring 18. In addition, a plurality of positioning protrusions and positioning grooves can be provided to enhance the connection reliability between the sleeve barrel 14 and the balance ring 18.

[0057] Optionally, the barrel wall of the sleeve barrel 14 may be a conical barrel wall, and the cross-sectional area of ​​one end of the conical barrel wall close to the first pulsator 13 is smaller than the cross-sectional area of ​​the other end. This arrangement can further control the size of the sleeve barrel 14 and enhance the economy of the washing machine.

[0058] Furthermore, in order to better realize the spin-drying operation, a spin-drying water outlet 141 can be provided on the top of the sleeve barrel 14, and the spin-drying water outlet 141 allows water to flow through, and the barrel wall of the sleeve barrel 14 allows water to flow through during the spin-drying process. The portion of the sleeve barrel 14 other than the aforementioned top is a water holding portion, and the inner cavity of the water holding portion is isolated from the inner cavity of the inner barrel 12. The inner cavity of the water holding portion is isolated from the inner cavity of the inner barrel 12 to prevent the water in the sleeve barrel 14 from flowing into the inner barrel 12, so that the water in the sleeve barrel 14 can be concentratedly used for washing clothes, thereby controlling the amount of water in the sleeve barrel 14; at the same time, such a setting can also form an independent space in the sleeve barrel 14 to prevent the clothes in the sleeve barrel 14 from being contaminated by other objects in the inner barrel 12. When the washing machine is spinning, the outer tub 14 rotates together with the inner tub 12, and the spun water will slide along the barrel wall of the outer tub 14. When the water slides to the spin outlet 141, it will further flow out of the outer tub 14, thereby completing the spin operation.

[0059] According to the above content, the water flow will slide along the barrel wall of the sleeve barrel 14 during the spin-drying process, so a small amount of water may not enter the spin-drying water outlet 141, but may be directly thrown out from the top edge of the sleeve barrel 14, which will have an adverse effect on the use of the washing machine. For this reason, a barrel cover 19 can also be provided, which is provided at the top of the sleeve barrel 14, and the spin-drying water outlet 141 is located between the barrel cover 19 and the second impeller 15. The barrel cover 19 includes a water retaining portion protruding toward the inside of the sleeve barrel 14 relative to the barrel wall of the sleeve barrel 14. Obviously, if the water slides to the top edge of the sleeve barrel 14, the water retaining portion of the barrel cover 19 will play a role to prevent the water flow from being thrown out of the washing machine. The barrel cover 19 can be provided with a claw 190, and the barrel cover 19 is connected to the sleeve barrel 14 through the claw 190.

[0060] The above-mentioned spin-drying water outlet hole 141 can be only one, but considering that the water output during spin-drying is large, multiple spin-drying water outlet holes 141 can be set, and each spin-drying water outlet hole 141 is arranged at intervals in the circumferential direction of the sleeve barrel 14. In addition, the shape, size and other parameters of the spin-drying water outlet hole 141 can be flexibly selected according to actual conditions, and this application does not limit this.

[0061] In one structure, the sleeve barrel 14 can be positioned and matched with the inner barrel 12 only in its peripheral direction, but in the axial direction of the sleeve barrel 14, the sleeve barrel 14 can be flexibly arranged relative to the inner barrel 12. The advantage of such an arrangement is that the disassembly and assembly operation between the sleeve barrel 14 and the inner barrel 12 will be simpler. However, this structure will cause the sleeve barrel 14 to easily move relative to the inner barrel 12 in its own axial direction when the washing machine is working, which is not conducive to the normal operation of the washing machine. Therefore, the movement of the sleeve barrel 14 can be limited in the axial direction of the sleeve barrel 14.

[0062] Preferably, a snap-in protrusion is provided on one of the barrel 14 and the balance ring 18, and a snap-in groove is provided on the other, and the snap-in protrusion and the snap-in groove can snap-fit ​​with each other, so that the barrel 14 and the balance ring 18 are positioned in the axial direction of the barrel 14, thereby limiting the displacement of the barrel 14 along its own axial direction. Figure 3 As shown, a clamping protrusion 142 is provided on the sleeve barrel 14, and a clamping groove 181 is provided on the balance ring 18. A plurality of clamping protrusions and clamping grooves can be provided to enhance the positioning reliability between the sleeve barrel 14 and the balance ring 18.

[0063] In the washing machine provided in the embodiment of the present application, the sleeve 14 can be taken out, and the taken out sleeve 14 can generally be directly placed on a placement base such as the ground or a table. However, when a key cover 17 is provided on the sleeve 14, in order to improve the support stability of the sleeve 14 on the placement base, the sleeve 14 may specifically include a water holding portion 143 and a support portion 144, which are fixedly connected, and the support portion 144 is a hollow structure, and the key cover 17 is located inside the support portion 144, and the support portion 144 can be supported on the placement base when the sleeve 14 is taken out. In other words, the key cover 17 is retracted relative to the support portion 144, so that the key cover 17 does not interfere with the support of the sleeve 14.

[0064] The support portion 144 may be a columnar structure or a conical structure. When the support portion 144 is a conical structure, the end of the support portion 144 away from the water holding portion 143 may be set larger, thereby allowing the barrel 14 to be more stably supported on the placement base.

[0065] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
