[0001] The invention belongs to the technical field of washing machines, and in particular relates to a pulsator washing machine. Background Art

[0002] Washing machines generally have two functions: washing and dehydrating. When washing, the washing tub is required not to rotate, while the impeller at the bottom of the washing tub rotates. When dehydrating, the washing tub and the impeller are required to rotate together.

[0003] In existing pulsator washing machines, switching between washing and spinning typically involves a clutch to change the motion of the washing tub and pulsator. This clutch is complex, bulky, and expensive, making it unsuitable for small washing machines like tabletop washing machines. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a pulsator washing machine, aiming to solve the problem that the clutch of the existing pulsator washing machine is large in size, high in cost, and not suitable for small-sized washing machines.

[0005] The embodiment of the present application is implemented as follows: a pulsator washing machine, comprising:

[0006] outer barrel;

[0007] a rotating shaft rotatably disposed on the bottom wall of the outer barrel, wherein a first end of the rotating shaft extends into the inner cavity of the outer barrel;

[0008] a washing tub, the washing tub being disposed in an inner cavity of the outer tub, the washing tub being connected to the rotating shaft via a first one-way bearing, the first one-way bearing only allowing the rotating shaft to rotate in a first clockwise direction relative to the washing tub;

[0009] a pulsator rotatably disposed on the inner bottom wall of the washing tub, wherein the first end of the rotating shaft passes through the washing tub and is fixedly connected to the pulsator;

[0010] A tub cover is pivotally connected to the outer tub, and the tub cover is suitable for covering the opening of the washing tub. A turntable is provided on the tub cover, and the turntable is connected to the tub cover through a second one-way bearing. When the tub cover covers the opening of the washing tub, the turntable abuts the washing tub, and the axes of the first one-way bearing and the second one-way bearing coincide so that the turntable and the washing tub rotate synchronously, and the second one-way bearing only allows the turntable to rotate in a second clockwise direction relative to the tub cover.

[0011] In a preferred embodiment of the present application, the barrel cover is provided with a first tooth portion, and the turntable is provided with a second tooth portion suitable for cooperating with the first tooth portion. When the barrel cover covers the opening of the washing tub, the first tooth portion and the second tooth portion are engaged to enable the turntable and the washing tub to rotate synchronously.

[0012] In a preferred embodiment of the present application, the bottom wall of the washing tub is provided with a through hole, the first one-way bearing is arranged in the through hole, the outer ring of the first one-way bearing abuts against the inner circumferential wall of the through hole, and first oil seals are provided at both axial ends of the through hole.

[0013] In a preferred embodiment of the present application, the washing tub includes a tub wall and a tub bottom provided at one end of the tub wall, the tub bottom is made of plastic, and the first one-way bearing and the tub bottom are injection molded in a mold.

[0014] In a preferred embodiment of the present application, a first groove is provided on the outer peripheral surface of the first one-way bearing.

[0017] In a preferred embodiment of the present application, a driving motor is provided on the outer side of the outer barrel, and the driving motor is directly connected to the second end of the rotating shaft to drive the rotating shaft to rotate.

[0018] In a preferred embodiment of the present application, the tub cover is slidably provided with a locking member, and a locking groove is provided on the outer tub. When the tub cover covers the opening of the washing tub, the locking member extends into the locking groove.

[0019] In a preferred embodiment of the present application, an elastic member for driving the locking member to enter the locking groove is further provided between the locking member and the barrel cover.

[0020] Embodiments of the present application provide a pulsator washing machine. When the rotating shaft rotates in a first clockwise direction, the shaft drives the pulsator to rotate. The outer and inner rings of the first one-way bearing are unlocked, preventing the washing tub from rotating with the pulsator. Furthermore, a second one-way bearing restricts the washing tub and turntable from rotating in the first clockwise direction. This allows the pulsator to rotate without the washing tub rotating, and the washing machine performs a wash function. When the rotating shaft rotates in a second clockwise direction, the shaft drives the pulsator to rotate. The outer and inner rings of the first one-way bearing are locked, allowing the shaft to rotate the washing tub in the second clockwise direction.

This allows the washing tub and pulsator to rotate synchronously, and the washing machine performs a spin function. The first and second one-way bearings cooperate to achieve switching between washing machine functions. Compared to existing washing machine clutches, the first and second one-way bearings occupy less space and are less expensive. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of this application is described in detail below in conjunction with specific embodiments.

[0033] In existing pulsator washing machines, the motor's output shaft is typically connected to the clutch's power shaft via a belt drive. The clutch then drives the washing tub and pulsator to rotate. Common washing machine clutches are based on a planetary gear system design. The central gear of the planetary gear system is fixedly connected to the power shaft, the ring gear is coaxially fixed to the washing tub, and the planetary carrier is fixedly connected to the pulsator shaft. This system's ring gear drives the washing tub in rotation, while the planetary carrier drives the pulsator in rotation. During the wash cycle, a brake mechanism restricts the rotation of the washing tub or the ring gear. This prevents the washing tub from rotating, while the planetary carrier can still drive the pulsator in rotation. During the spin cycle, a clutch mechanism connects the ring gear to the central gear, releasing the brake mechanism. This deactivates the entire planetary gear system, allowing it to rotate as a single unit. This allows the washing tub and pulsator to rotate synchronously. However, this clutch structure is extremely complex. In addition to the planetary gear system, it also requires a brake mechanism, a clutch mechanism, and a drive mechanism to activate the brake and clutch mechanisms. This results in a bulky and costly clutch. Installing a clutch in a small washing machine such as a desktop washing machine will make the washing machine larger and increase the cost, which goes against the original design intention. Therefore, a new solution is needed to realize the switching of the washing and dehydration functions of the washing machine. For this purpose, the present application provides a pulsator washing machine.

[0034] like Figure 1 and Figure 2 , which is a schematic structural diagram of a pulsator washing machine provided in an embodiment of the present application, the pulsator washing machine includes: an outer barrel 100, a rotating shaft 610, a washing barrel 200, a pulsator 300, and a barrel cover 400.

[0035] like Figure 1 and Figure 2As shown, the outer barrel 100 is a barrel-shaped structure with an open upper end and a closed lower end. In some embodiments, a shell (not shown) is further provided on the outer side of the outer barrel 100.

[0036] The rotating shaft 610 is rotatably mounted on the bottom wall of the outer barrel 100, and the first end of the rotating shaft 610 extends into the inner cavity of the outer barrel 100. Figure 2 As shown, the rotating shaft 610 is arranged along the axial direction of the outer barrel 100 and is rotatably set at the center of the bottom wall of the outer barrel 100. One end of the rotating shaft 610 is located in the inner cavity of the outer barrel 100, and the other end extends to the outside of the outer barrel 100 to connect to the drive motor 500.

[0037] like Figure 2 As shown, the washing tub 200 is disposed in the inner cavity of the outer tub 100, and the washing tub 200 is connected to the rotating shaft 610 via a first one-way bearing 620. The first one-way bearing 620 only allows the rotating shaft 610 to rotate in a first clockwise direction relative to the washing tub 200. Specifically, as Figure 3 and Figure 4 As shown, the washing tub 200 is coaxially arranged with the outer tub 100. A first one-way bearing 620 is disposed on the bottom wall of the washing tub 200. The washing tub 200 is fixedly connected to the outer ring of the first one-way bearing 620, and the inner ring of the first one-way bearing 620 is mounted on the rotating shaft 610. The first one-way bearing 620 only allows the rotating shaft 610 to rotate in a first clockwise direction relative to the washing tub 200. This allows the rotating shaft 610 to rotate freely in the first clockwise direction relative to the washing tub 200 without causing the washing tub 200 to rotate. However, when the rotating shaft 610 rotates in a second clockwise direction relative to the washing tub 200, the inner and outer rings of the first one-way bearing 620 lock, allowing the rotating shaft 610 to rotate with the washing tub 200. In some preferred embodiments, when viewed from the top of the pulsator washing machine, the first clockwise direction is counterclockwise, and the second clockwise direction is clockwise.

[0038] like Figure 2 As shown, the pulsator 300 is rotatably mounted on the inner bottom wall of the washing tub 200, and the first end of the rotating shaft 610 passes through the washing tub 200 and is fixedly connected to the pulsator 300. Figure 4 As shown, a steel ring 310 is provided at the center of the impeller 300, and the steel ring 310 is injection-molded with the impeller 300 to strengthen the connection between the steel ring 310 and the impeller 300. The steel ring 310 is connected with the rotating shaft 610 through the trimmed circular hole to limit the rotation between the steel ring 310 and the rotating shaft 610, and the steel ring 310 is axially limited by a locking nut (not shown in the figure), so that the fixed connection between the impeller 300 and the rotating shaft 610 is achieved, and the impeller 300 and the rotating shaft 610 rotate synchronously in both directions.

[0039] like Figure 1 、 Figure 2 and Figure 6 As shown, the barrel cover 400 is pivotally connected to the outer barrel 100, and the barrel cover 400 is suitable for covering the opening of the washing tub 200. A turntable 710 is provided on the barrel cover 400, and the turntable 710 is connected to the barrel cover 400 through a second one-way bearing 720. When the barrel cover 400 covers the opening of the washing tub 200, the turntable 710 abuts against the washing tub 200, and the axes of the first one-way bearing 620 and the second one-way bearing 720 coincide. The second one-way bearing 720 only allows the turntable 710 to rotate relative to the barrel cover 400 in the second clockwise direction. Figure 1 and Figure 2 As shown, the washing tub 200 is a tub-shaped structure with an open upper end, and the tub cover 400 can be flipped relative to the outer tub 100 to cover or open the opening of the washing tub 200.

[0040] It is understandable that when the rotating shaft 610 rotates in the first clockwise direction, although it will not drive the washing tub 200 to rotate, the clothes in the washing tub 200 will still drive the washing tub 200 to rotate, resulting in poor washing effect. By limiting the rotation of the washing tub 200 in the first clockwise direction by the second one-way bearing 720 and the turntable 710, the friction between the clothes and the washing tub 200 can be increased, thereby improving the washing effect.

[0041] In this embodiment, when the rotating shaft 610 rotates in a first clockwise direction, it drives the pulsator 300 to rotate. The outer and inner rings of the first one-way bearing 620 are unlocked, preventing the drum 200 from rotating with the pulsator 300. Furthermore, the second one-way bearing 720 restricts the drum 200 and the turntable 710 from rotating in the first clockwise direction. This allows the pulsator 300 to rotate without rotating the drum 200, and the washing machine performs the wash function. When the rotating shaft 610 rotates in a second clockwise direction, it drives the pulsator 300 to rotate. The outer and inner rings of the first one-way bearing 620 are locked, driving the drum 200 to rotate in the second clockwise direction. The second one-way bearing 720 is unlocked, allowing the drum 200 and turntable 710 to rotate in the second clockwise direction. This allows the drum 200 and pulsator 300 to rotate synchronously, allowing the washing machine to perform the spin function. The switching of the washing machine function can be achieved through the cooperation of the first one-way bearing 620 and the second one-way bearing 720. Compared with the clutch of the existing pulsator washing machine, the first one-way bearing and the second one-way bearing 720 occupy less space and have lower cost.

[0042] like Figure 5As shown, in some embodiments of the present application, a mounting post 711 is provided on the turntable 710, and a second connecting sleeve 730 is sleeved on the mounting post 711. The second connecting sleeve 730 and the mounting post 711 are locked and fixed by a locking screw 740. The inner ring of the second one-way bearing 720 is sleeved on the second connecting sleeve 730. Two convex rings are also formed on the second connecting sleeve 730, and the two convex rings respectively abut against the two ends of the second one-way bearing 720 to achieve axial limitation of the second one-way bearing 720. Figure 6 As shown, the inner ring of the second one-way bearing 720 is provided with a slot, and the outer periphery of the second connecting sleeve 730 is provided with a protrusion that cooperates with the slot. The cooperation between the protrusion and the slot restricts the rotation of the second connecting sleeve 730 relative to the second one-way bearing 720. The mounting post 711 has a circular cross-section with cut edges, and the second connecting sleeve 730 is provided with a circular through-hole with cut edges. In this way, when the mounting post 711 passes through the through-hole of the first connecting sleeve 730, it can restrict the rotation between the second connecting sleeve 730 and the rotating disk 710.

[0043] like Figure 5 As shown, in some embodiments of the present application, the barrel cover 400 is provided with a mounting hole, the second one-way bearing 720 is disposed in the mounting hole, and the outer ring of the second one-way bearing 720 is fixed to the barrel cover 400. The lower end of the second connecting sleeve 730 is also provided with a sleeve 750, and the outer side of the sleeve 750 is provided with a second oil seal 820, and the outer peripheral surface of the second oil seal 820 abuts against the peripheral wall of the mounting hole. The second oil seal 820 can prevent water from invading the second one-way bearing 720. In addition, in some embodiments, the second oil seal 820 is fixed to the barrel cover 400, and the sleeve 750 is fixed to the second connecting sleeve 730. When the second connecting sleeve 730 rotates, the friction between the sleeve 750 and the second oil seal 820 can effectively protect the second connecting sleeve 730.

[0044] like Figure 6 As shown, in some embodiments of the present application, the barrel cover 400 is provided with a first tooth portion 231, and the turntable 710 is provided with a second tooth portion 712 suitable for cooperating with the first tooth portion 231. When the barrel cover 400 covers the opening of the washing tub 200, the first tooth portion 231 and the second tooth portion 712 are engaged to enable the turntable 710 and the washing tub 200 to rotate together.

[0045] Specifically, such as Figure 3 As shown, a barrel ring 230 is fixedly provided on the top of the barrel wall 210. Figure 6As shown, the first teeth 231 are provided on the upper surface of the drum ring 230, circumferentially surrounding the drum ring 230. The second teeth 712 are provided on the lower end surface of the turntable 710, circumferentially surrounding the turntable 710. In this embodiment, the engagement of the first teeth 231 and the second teeth 712 allows the turntable 710 to be better connected to the washing tub 200, thereby restricting the washing tub 200 from rotating in the first clockwise direction.

[0046] like Figure 4 As shown, in some embodiments of the present application, the bottom wall of the washing tub 200 is provided with a perforation, and the first one-way bearing 620 is disposed within the perforation. The outer ring of the first one-way bearing 620 abuts the inner circumferential wall of the perforation, and first oil seals 810 are disposed at both axial ends of the perforation. In this embodiment, the two first oil seals 810 prevent external water from entering the first one-way bearing 620, thereby protecting the first one-way bearing 620 and extending its service life.

[0047] like Figure 3 As shown, in some embodiments of the present application, the washing tub 200 includes a tub wall 210 and a tub bottom 220 disposed at one end of the tub wall 210. The tub bottom 220 is made of plastic, and the first one-way bearing 620 is injection-molded with the tub bottom 220. In this embodiment, the first one-way bearing 620 is injection-molded with the tub bottom 220 to simplify installation of the first one-way bearing 620. Furthermore, ensuring the connection strength between the outer ring of the first one-way bearing 620 and the tub bottom 220 ensures that the first one-way bearing 620 can drive the washing tub 200 to rotate.

[0048] In some embodiments of the present application, a first retaining groove is provided on the outer circumferential surface of the first one-way bearing 620. In this embodiment, when the rotating shaft 610 rotates in the second clockwise direction, the washing tub 200 needs to be driven to rotate by the first one-way bearing 620. Torque needs to be transmitted between the first one-way bearing 620 and the washing tub 200. By providing the first retaining groove on the outer ring of the first one-way bearing 620, the plastic melt will fill the first retaining groove when the bottom 220 of the washing tub 200 is in-molded. This can further improve the connection strength between the first one-way bearing 620 and the bottom 220, thereby improving torque transmission.

[0049] In some embodiments of the present application, Figure 3 and Figure 4As shown, the inner circumference of the inner ring of the first one-way bearing 620 is provided with a second slot, the inner ring of the first one-way bearing 620 is connected to the first connecting sleeve 630, the outer circumference of the first connecting sleeve 630 is provided with a clamping portion that cooperates with the second slot, the first connecting sleeve 630 is provided with a trimmed circular hole along the axial direction, the rotating shaft 610 is provided with a connecting portion suitable for connecting with the trimmed circular hole, and the inner wall of the perforated first oil seal 810 abuts against the first connecting sleeve 630.

[0050] In this embodiment, the second retaining groove on the inner ring of the first one-way bearing 620 cooperates with the retaining portion of the first connecting sleeve 630 to limit rotation between the first one-way bearing 620 and the first connecting sleeve 630. The trimmed circular hole and the connecting portion with a trimmed circular cross-section cooperate to limit rotation between the rotating shaft 610 and the first connecting sleeve 630. This allows the rotating shaft 610 to transfer torque to the washing tub 200, driving the washing tub 200 to rotate. Furthermore, the present application pre-installs the first connecting sleeve 630 on the rotating shaft 610, where it abuts against the first oil seal 810. This allows the rotating shaft 610 to rotate, and friction between the first connecting sleeve 630 and the first oil seal 810 effectively protects the rotating shaft 610 from wear. Furthermore, subsequent maintenance only requires replacing the first connecting sleeve 630, eliminating the need to replace the entire rotating shaft 610.

[0051] In some embodiments of the present application, the second one-way bearing 720 is injection-molded with the barrel cover 400. In this embodiment, the second one-way bearing 720 is pre-placed in the mold cavity. After the plastic melt is injected into the mold cavity and solidifies, the plastic melt automatically connects to the second one-way bearing 720. This eliminates the need to separately install the second one-way bearing 720, simplifying the assembly process. Compared to existing methods of installing bearings through an interference fit, the solution of the present application can provide a more reliable connection between the second one-way bearing 720 and the barrel cover 400.

[0052] like Figure 2 As shown, in this embodiment, a drive motor 500 is provided on the outside of the outer tub 100. The drive motor 500 is directly connected to the second end of the rotating shaft 610 to drive the rotating shaft 610 to rotate. In this embodiment, the rotating shaft 610 is directly driven by the motor to rotate, eliminating the need for a clutch, simplifying the structure and saving costs.

[0053] like Figure 1 and Figure 6As shown, in some embodiments of the application, the lid 400 is slidably provided with a locking member 410, and the outer tub 100 is provided with a locking groove. When the lid 400 covers the opening of the washing tub 200, the locking member 410 extends into the locking groove. An elastic member 420 is further provided between the locking member 410 and the lid 400 for driving the locking member 410 into the locking groove. In this embodiment, the locking member 410 is engaged with the locking groove of the outer tub 100 to ensure that the lid 400 can be fastened to the washing tub 200 when the washing machine is in operation, so that when the washing tub 200 rotates, the rotation of the turntable 710 can be driven normally.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
