Description

Technical Field

[0001] This invention relates to the field of laundry equipment technology, and more specifically, to a washing machine. Background Technology

[0002] Most washing machines on the market are single-drum washing machines, which are inconvenient for separating the clothes to be washed. For example, they cannot separate adult and children's clothes, maternity and baby clothes, clothes that fade and clothes that do not fade, underwear and outerwear, etc. If they are washed separately, they need to be washed multiple times, which wastes time. Mixing clothes can easily cause fading, staining, and secondary pollution.

[0003] In view of this, the prior art discloses a twin-tub washing machine, which includes a frame, a drum assembly, and a pulsator assembly. The frame is divided into upper and lower drum mounting spaces and pulsator mounting spaces by a middle partition. The drum assembly is installed in its corresponding drum mounting space, and the pulsator assembly is slidably installed in its corresponding pulsator mounting space via a specific sliding mechanism. This twin-tub washing machine can wash clothes separately, combining the advantages of both drum and pulsator washing machines. However, the independent arrangement of the drum and pulsator assemblies in this twin-tub washing machine increases component costs, reduces space utilization, and results in higher overall processing and operating costs.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, and to address the issues of high component costs and low space utilization in existing twin-tub washing machines.

[0006] The present invention provides a washing machine, comprising: a housing having a receiving cavity therein; an impeller assembly including an impeller outer drum located within the receiving cavity; a drum assembly including a drum outer drum located within the receiving cavity, the drum outer drum being disposed on one side of the impeller outer drum; and a connecting assembly connected to the drum outer drum and the impeller outer drum, and configured to allow the drum outer drum and the impeller outer drum to act as counterweights to each other.

[0007] By employing the above technical solution, this invention achieves diversified washing functions and efficient space utilization by simultaneously arranging the impeller assembly and the drum assembly within the same housing. Furthermore, by connecting the impeller outer drum and the drum outer drum with connecting components respectively, the impeller outer drum and the drum outer drum can act as counterweights to each other. This not only improves the overall stability of the washing machine and reduces shaking caused by the independent operation of a single component, thus enhancing the washing effect and user experience, but also eliminates the need for additional counterweights for the impeller outer drum and the drum outer drum, reducing component costs, space occupation, manufacturing costs, and operating costs.

[0008] In the specific embodiment of the washing machine described above, one end of the connecting component is connected to the outer side of the drum outer tub near the pulsator outer tub, and the other end of the connecting component is connected to the outer side of the pulsator outer tub near the drum outer tub.

[0009] By adopting the above technical solution, the design of the connecting components makes the connection between the pulsator outer drum and the drum outer drum more stable. Furthermore, by connecting them close to each other, space is effectively utilized, enhancing the overall weight distribution. This design further reduces the shaking of the washing machine during operation, improving stability and safety.

[0010] In the specific embodiment of the washing machine described above, the length direction of the connecting component is perpendicular to the opening direction of the outer drum of the impeller.

[0011] With the above technical solution, the length direction of the connecting component is perpendicular to the opening direction of the outer drum of the impeller, ensuring that the connecting component provides effective counterweight and stability support without affecting the normal opening and closing of the outer drum of the impeller. This design optimizes the internal structural layout of the washing machine and improves space utilization.

[0012] In the specific embodiment of the washing machine described above, there are two connecting components, and the two connecting components are distributed along the length direction of the outer drum of the impeller.

[0013] By employing the above technical solution, two connecting components are distributed along the length of the impeller outer cylinder, which further enhances the connection strength and stability between the impeller outer cylinder and the drum outer cylinder.

[0014] In the specific embodiment of the washing machine described above, the connecting assembly includes a first shock absorber, one end of which is connected to the outer drum of the drum, and the other end of which is connected to the outer drum of the impeller. The first shock absorber is configured to reduce the relative sway between the outer drum of the drum and the outer drum of the impeller.

[0015] By adopting the above technical solution, the first shock absorber effectively reduces the relative sway between the pulsator outer drum and the drum outer drum, improving the stability and durability of the washing machine. At the same time, the design of the first shock absorber makes the washing machine quieter during operation, reducing noise and wear caused by swaying.

[0016] In the specific embodiment of the washing machine described above, the connecting assembly includes a connecting rod, one end of which is connected to the outer drum of the drum, and the other end of which is connected to the outer drum of the impeller. The connecting rod is configured to enable the outer drum of the drum and the outer drum of the impeller to shake synchronously.

[0017] When the above technical solution is adopted, the connecting component adopts a connecting rod design, which enables the outer drum of the impeller and the outer drum of the drum to shake synchronously, thereby reducing the overall shaking amplitude of the washing machine and improving stability.

[0018] In the specific embodiment of the washing machine described above, a second shock absorber is provided at the lower end of the outer drum along the height direction of the outer drum. The second shock absorber is configured to reduce the vibration of the outer drum in the height direction.

[0019] By adopting the above technical solution, a second shock absorber is installed at the lower end of the outer drum, which effectively reduces the vibration of the outer drum in the height direction and improves the stability of the washing machine. At the same time, it reduces noise and wear caused by vibration, extending the service life of the washing machine.

[0020] In the specific embodiment of the washing machine described above, both the first shock absorber and the second shock absorber include a friction rod and a damping cylinder. One end of the friction rod extends into the damping cylinder from one end of the damping cylinder and is slidably connected to the damping cylinder.

[0021] When the above technical solution is adopted, both the first and second shock absorbers use a combination design of friction rod and damping cylinder, which provides an effective shock absorption effect.

[0022] In the specific embodiment of the washing machine described above, a drum loading port is provided on the side of the outer drum away from the outer drum of the impeller, and the housing is provided with an impeller top cover and a drum side cover. The impeller top cover is positioned at the upper end of the outer drum of the impeller, and the drum side cover is positioned on the side of the outer drum of the drum away from the outer drum of the impeller, at a position corresponding to the loading port.

[0023] With the above technical solution, a drum loading port is located on the side of the outer drum away from the pulsator drum, and is equipped with a corresponding pulsator top cover and drum side cover, allowing users to choose different washing methods according to different types of clothing. This design improves the flexibility and practicality of the washing machine, meeting the diverse washing needs of users.

[0024] In the specific embodiment of the washing machine described above, the upper end of the outer drum is provided with a suspension spring connected to the housing; and / or the outer side of the pulsator outer drum is provided with a suspension rod connected to the housing, the number of the suspension rods being two, and the two suspension rods being symmetrically arranged relative to the pulsator outer drum.

[0025] By adopting the above technical solution, a suspension spring is installed at the upper end of the drum outer tub, and a suspension rod is installed on the outside of the impeller outer tub. This not only provides additional stability and support but also optimizes the internal structural layout of the washing machine. This design makes the washing machine run more smoothly, reducing noise and wear caused by shaking. Attached Figure Description

Furthermore, by using the connecting assembly 4 to act as counterweights for the pulsator outer tub 31 and the drum outer tub 21, the overall stability of the washing machine is improved, and the shaking caused by the independent operation of a single component is reduced, thus enhancing the washing effect and user experience. Simultaneously, it eliminates the need for counterweights on the pulsator outer tub 31 and the drum outer tub 21, reducing manufacturing costs.

[0037] like Figures 1-4 As shown, in one or more embodiments, the washing machine of the present invention includes a housing 1, a drum assembly 2, a pulsator assembly 3, and a connecting assembly 4. The drum assembly 2, the pulsator assembly 3, and the connecting assembly 4 are all disposed within the housing 1.

Figures 1-4 The side facing outwards in the direction perpendicular to the paper; the technical term "back side" refers to... Figures 1-4 The side perpendicular to the paper and pointing inwards; the technical terms "left side," "right side," "top side," and "bottom side" are all based on Figure 1 Regarding the directions shown.

[0039] like Figures 1-4 As shown, in one or more embodiments, the housing 1 has a generally cuboid shape. Alternatively, the housing 1 may also be configured as a cube or other suitable shape. A generally hollow receiving cavity 11 is provided inside the housing 1, which is configured to accommodate the roller assembly 2 and the impeller assembly 3.

[0040] like Figure 1 and Figure 2 As shown, in one or more embodiments, a pulsator loading port (not shown in the figure) is provided on the top plate of the housing 1, which facilitates the addition of clothing into the pulsator assembly 3. That is, the rotation center of the pulsator assembly 3 extends approximately in the vertical direction. Specifically, the pulsator loading port is located on the right side of the top plate of the housing. Alternatively, the pulsator loading port can also be located on the left side of the top plate of the housing or other suitable positions. A pulsator cover 13 is provided inside the pulsator loading port, and the pulsator cover 13 is openable and closable within the pulsator loading port, allowing the pulsator loading port to be opened or closed. It should be noted that the connection method between the pulsator cover 13 and the pulsator loading port is prior art and will not be described in detail here.

[0041] like Figure 1 and Figure 2 As shown, in one or more embodiments, a roller loading port (not shown) is provided on the left side plate of the housing 1, which facilitates the addition of clothing into the roller assembly 2. That is, the rotation center of the roller assembly 2 extends approximately in the left-right direction. A roller side cover 12 is provided inside the roller loading port, and the roller side cover 12 is openable and closable within the roller loading port, allowing the roller loading port to be opened or closed. It should be noted that the connection method between the roller side cover 12 and the roller loading port is prior art and will not be described further here. Alternatively, the roller loading port can be located on the front, rear, or right side plate of the housing 1. Correspondingly, the roller side cover 12 can be located on the front, rear, or right side plate of the housing 1, as long as clothing can be added into the roller assembly 2 through the roller loading port.

[0042] like Figure 3 and Figure 4 As shown, in one or more embodiments, a roller loading port (not shown) is provided on the left side of the top plate of the housing 1, which facilitates the addition of clothing into the roller assembly 2. Correspondingly, an opening communicating with the roller loading port is provided on the circumferential wall of the roller assembly 2, allowing clothing to enter the interior of the roller assembly 2 through the opening. A roller cover 14 is provided inside the roller loading port, and the roller cover 14 is openable and closable within the roller loading port, allowing the roller loading port to be opened or closed. It should be noted that the connection method between the roller cover 14 and the roller loading port is prior art and will not be described further here.

[0043] like Figure 1 and Figure 2 As shown, in one or more embodiments, the impeller assembly 3 includes components such as an outer impeller cylinder 31, an inner impeller cylinder 32, a suspension rod 33, and an impeller drive 34. The outer impeller cylinder 31 is located inside the housing 1 near the right side, with its opening facing the impeller cover 13 on the housing 1. Alternatively, the outer impeller cylinder 31 can be located inside the housing 1 near the left side. Alternatively, the outer impeller cylinder 31 can be located inside the housing 1 near the center. The upper end of the outer impeller cylinder 31 is open, allowing it to hold washing water. The inner impeller cylinder 32 is located inside the outer impeller cylinder 31, with its upper end also open, and contains an impeller 35. The impeller drive 34 is located on the lower side of the outer drum 31. The output shaft of the impeller drive 34 passes through the outer drum 31 and the inner drum 32 and connects to the impeller 35. The impeller drive 34 can drive the impeller 35 to rotate, which in turn drives the clothes and water in the inner drum 32 to rotate. This causes the clothes to rub against the inner walls of the impeller 35 and the inner drum 32, thus cleaning the clothes. In one or more embodiments, there are two hangers 33, located on the left and right sides of the outer drum 31, respectively. One end of the hanger 33 is fixedly connected to the outer drum 31, and the other end is connected to the inner side of the upper wall of the housing 1. The two hangers 33 not only provide additional stability and support but also optimize the internal structural layout of the washing machine, making the washing machine run more smoothly and reducing noise and wear caused by shaking. Alternatively, there can be three, four, or five hangers 33. Alternatively, the hangers 33 can also be connected to the inner left wall of the housing 1.

[0044] like Figure 1 and Figure 2As shown, in one or more embodiments, the roller assembly 2 includes components such as an outer roller 21, an inner roller 22, a roller drive 24, a suspension spring 23, and a second shock absorber 25. The outer roller 21 and the impeller outer roller 31 are approximately on the same horizontal plane, with the outer roller 21 positioned on the left side of the housing 1. Alternatively, the outer roller 21 can be positioned on the right side of the housing 1, and correspondingly, the impeller outer roller 31 can be positioned on the left side of the housing 1. Alternatively, the outer roller 21 can be positioned in the middle of the housing 1. Alternatively, the outer roller 21 and the impeller outer roller 31 can be arranged perpendicular to the plane of the paper. In one or more embodiments, the inner roller 22 is disposed inside the outer roller 21, and the inner roller 22 has an opening facing to the left, facilitating the placement of clothing inside the inner roller 22. In one or more embodiments, the roller drive 24 is located on the right side of the outer roller 21, and the drive shaft of the roller drive 24 passes through the outer roller 21 and connects to the inner roller 22. The drum drive 24 drives the inner drum 22 to rotate, thus washing the clothes inside the inner drum 22. In one or more embodiments, one end of the suspension spring 23 is connected to the outer drum 21, and the other end of the suspension spring 23 is connected to the upper wall of the housing 1. The suspension spring 23 provides an upward pulling force to the outer drum 21, providing additional stability and support, making the washing machine run more smoothly and reducing noise and wear caused by shaking. Alternatively, the number of suspension springs 23 can be one, two, three, or four, as long as they can provide an upward pulling force to the outer drum 21.

[0045] like Figure 1 and Figure 2 As shown, in one or more embodiments, the second shock absorber 25 is arranged generally vertically. The lower end of the second shock absorber 25 is connected to the lower wall of the housing 1, and the upper end of the second shock absorber 25 is connected to the bottom of the outer drum 21. The second shock absorber 25 is configured to reduce the vertical vibration of the outer drum 21. Thus, by providing the second shock absorber 25 at the lower end of the outer drum 21, the vertical vibration of the outer drum 21 is effectively reduced, improving the stability of the washing machine. Simultaneously, noise and wear caused by vibration are reduced, extending the service life of the washing machine. Alternatively, the second shock absorber 25 may not be provided, or multiple second shock absorbers 25 may be provided.

[0046] like Figure 1 and Figure 2As shown, in one or more embodiments, the second shock absorber 25 includes a friction rod 252 and a damping cylinder 251. The upper end of the friction rod 252 is fixedly connected to the bottom of the outer drum 21. Friction grooves are provided on the friction rod 252, and the lower end of the friction rod 252 is inserted into the damping cylinder 251 through the upper end of the damping cylinder 251, with the friction rod 252 and damping cylinder 251 slidably connected. The friction grooves on the friction rod 252 rub against the inner wall of the damping cylinder 251, thereby increasing the resistance that the second shock absorber 25 needs to overcome during extension and retraction, thus completing the shock absorption of the outer drum 21. The lower end of the damping cylinder 251 is connected to the lower wall of the housing 1. Thus, the second shock absorber 25, with its combined design of the friction rod 252 and damping cylinder 251, provides an effective shock absorption effect. It should be noted that the second shock absorber 25 can also adopt other structures, as long as it can effectively absorb the shock of the outer drum 21.

[0047] like Figure 3 and Figure 4 As shown, in one or more embodiments, the upper end of the outer drum 21 is open, and the opening of the outer drum 21 faces the upper drum cover 14. The inner drum 22 rotates under the action of the drum drive 24. An inner drum loading port is provided on the left-right extending surface of the inner drum 22. The inner drum loading port is equipped with an inner drum door 221. When the inner drum door 221 is facing upwards, it faces the upper drum cover 14, allowing clothing to be placed into the inner drum 22 through the inner drum door 221. In one or more embodiments, one end of the inner drum door 221 is hinged to the inner drum loading port, and a buckle is provided on the other end of the inner drum door 221. A latch is provided on the outer wall of the inner drum 22 to engage with the buckle. The inner drum door 221 closes the inner drum loading port through the engagement of the latch and the buckle. Alternatively, the specific connection method of the inner drum door 221 can be set according to actual needs. For example, a slide rail can be set on the outside of the inner drum 22, and the inner drum door 221 can be slidably connected to the slide rail to realize the opening and closing of the inner drum inlet.

[0048] like Figure 1As shown, in one or more embodiments, one end of the connecting component 4 is connected to the outer right side of the drum outer tub 21, and the other end of the connecting component 4 is connected to the outer right side of the impeller outer tub 31. This design of the connecting component 4 makes the connection between the impeller outer tub 31 and the drum outer tub 21 more stable, and by connecting them close to each other, it effectively utilizes space and enhances the overall counterweight effect. This design further reduces the shaking of the washing machine during operation, improving stability and safety. Alternatively, the connecting component 4 can also be connected to other positions on the drum outer tub 21 and the impeller outer tub 31. In one or more embodiments, the length direction of the connecting component 4 is perpendicular to the opening direction of the impeller outer tub 31. Alternatively, the length direction of the connecting component 4 can also be set at an angle of 80 degrees, 70 degrees, 60 degrees, etc., to the opening direction of the impeller outer tub 31. Figure 1 As shown, in one or more embodiments, the number of connecting components 4 is two, and the two connecting components 4 are distributed along the length direction of the impeller outer cylinder 31. One connecting component 4 is located at the upper position of the impeller outer cylinder 31, and the other connecting component 4 is located at the lower position of the impeller outer cylinder 31. Thus, by using two connecting components 4 distributed along the length direction of the impeller outer cylinder 31, the connection strength and stability between the impeller outer cylinder 31 and the drum outer cylinder 21 are further enhanced. Alternatively, as... Figure 2 As shown, the two connecting components 4 can both be set on the lower side of the outer cylinder 21 of the roller and are spaced apart.

[0049] like Figure 1 and Figure 4 As shown, in one or more embodiments, the connecting assembly 4 includes a connecting rod. One end of the connecting rod is connected to the right side of the outer drum 21, and the other end is connected to the left side of the outer impeller drum 31. The connecting rod is configured to enable the outer drum 21 and the outer impeller drum 31 to shake synchronously. Thus, the connecting assembly 4, with its connecting rod design, allows the outer impeller drum 31 and the outer drum 21 to shake synchronously, thereby reducing the overall shaking amplitude of the washing machine and improving stability.

[0050] like Figure 2 and Figure 3 As shown, in one or more embodiments, the connecting assembly 4 includes a first shock absorber. One end of the first shock absorber is connected to the right side of the outer drum 21, and the other end is connected to the left side of the outer impeller drum 31. The first shock absorber is configured to reduce the relative sway between the outer drum 21 and the outer impeller drum 31. Thus, the first shock absorber effectively reduces the relative sway between the outer impeller drum 31 and the outer drum 21, improving the stability and durability of the washing machine. It should be noted that the first shock absorber and the second shock absorber 25 have the same structure in the connecting assembly 4, and will not be described again here. Of course, the first shock absorber can also adopt different structures as long as the same effect is achieved.
