Description
Technical Field
[0001] This invention relates to the technical field of washing machines, and particularly to a mini washing machine. Background Technology
[0002] Patent CN2017214151985 discloses a dynamic balancing device, inner drum assembly, and drum washing machine for a drum-type washing machine. From the background technology of this patent, it can be seen that the vibration source of existing drum-type washing machines mainly comes from the suspension system. The suspension system, as the core component of the drum washing machine, mainly includes an inner drum rotor, an outer drum assembly, a drive motor, a counterweight, suspension springs, and a damper. The inner drum rotor is a high-speed rotating structure, mainly connected to the outer drum of the washing machine through bearings, and driven to rotate by the motor through a transmission belt, thereby realizing functions such as washing and spin-drying.
[0003] When there are clothes unevenly loaded in the inner drum of the inner drum rotor, the rotor will rotate asymmetrically, which will cause vibration of the suspension system and even the entire washing machine, seriously affecting the user experience and the service life of the washing machine.
[0004] Current washing machines mainly use a combination of counterweights, suspension springs, and dampers on the outer drum for dynamic balance and vibration reduction. These vibration reduction designs often result in an abnormally heavy suspension system.
[0005] As can be seen from the above description, the dynamic balancing structure of existing washing machines is relatively complex, occupies a large amount of internal space, and is not conducive to reducing the size of the washing machine.

[0043] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0044] As shown in Figures 1 to 17, a mini washing machine in this embodiment includes a washing machine housing 5, a drive assembly 2, and a drum assembly. The washing machine housing 5 includes a water tank 51 and an outer shell 52. The water tank 51 is disposed inside the outer shell 52, and an assembly cavity 53 is formed between the two. The drive assembly 2 is disposed inside the assembly cavity 53, and the drum assembly is disposed inside the water tank 51.
[0045] The roller assembly includes a roller body 1 and a dynamic balancing device. The dynamic balancing device includes an eccentric component 3 and an elastic component 4 disposed at both ends of the roller body 1. The eccentric component 3 is disposed between the drive component 2 and the roller body 1. The eccentric component 3 enables the drive component 2 to drive the roller body 1 to perform eccentric motion.
[0046] The elastic component 4 is disposed between the roller body 1 and the water tank 51. The elastic component 4 can elastically deform with the movement of the roller body 1 to achieve the effect of dynamic balance.
[0047] Compared to older dynamic balancing devices that use components such as suspension springs and dampers, this design offers advantages over traditional methods.
[0048] The proposed dynamic balancing device only requires the setting of elastic component 4 and eccentric component 3 to achieve the effect of dynamic balancing. It has fewer parts, a simple structure, and occupies less internal space in the washing machine, which helps to reduce the size of the washing machine, making it more miniaturized and easier for users to carry.
[0049] Preferably, as shown in Figures 1 to 17, the mini washing machine in this embodiment further includes a drying component 6, which is disposed in the assembly cavity 53. The water tank 51 has an air outlet 511 on its side wall, and the output end of the drying component 6 is sealed to the air outlet 511. By adding the drying component 6, the mini washing machine is equipped with a drying function, increasing the diversity of washing machine functions.
[0050] Preferably, the drying assembly 6 includes a blower 61, an air outlet 62, and a heating element 63. One end of the air outlet 62 is sealed to the output end of the blower 61, and the other end of the air outlet 62 is sealed to the air outlet 511. The heating element 63 is disposed in the air outlet 62 to heat the airflow blown out by the blower 61 to form hot air. The hot air is blown into the water tank 51 through the air outlet 511 to dry the clothes in the drum body 1.
[0051] Preferably, the air outlet channel 62 includes a first channel 621 and a second channel 622 connected in sequence. The blower 61 is connected to the side wall of the first channel 621, the heating element 63 is disposed in the first channel 621, one end of the second channel 622 is connected to the bottom of the first channel 621, and the side wall of the second channel 622 is provided with an air outlet end corresponding to the air outlet hole 511. This design can extend the length of the air outlet channel 62 so that the air outlet channel 62 has a sufficient heat exchange range, can extend the heating time of the airflow, and can raise the temperature of the airflow to a sufficient level to ensure that clothes can be dried.
[0052] Furthermore, the first channel 621 and the second channel 622 are connected to form a curved air outlet channel 62. Since the airflow passes through the curve, the wind noise problem can be reduced, making the blown airflow more stable and quiet, thereby improving the quietness of the mini washing machine.
[0053] Preferably, the drive component 2 is located at the corner of the air outlet duct 62, which makes the structure of the washing machine more compact and further reduces the size of the washing machine.
[0054] Preferably, the highest water level in the water tank 51 is lower than the plane where the second channel 622 and the first channel 621 connect, so as to ensure that when the washing machine is in the washing state, the water in the water tank 51 will not enter the first channel 621, and the water will not affect the blower 61 and the heating element 63, ensuring the normal operation of the drying assembly 6 and avoiding the occurrence of safety problems.
[0055] Preferably, the heating element 63 can be a common heating component such as a heating wire or a heating rod.
[0056] Preferably, the roller body 1 is provided with a rotating shaft component 11, the rotating shaft component 11 is connected to the elastic component 4, and the roller body 1 is also provided with a rotating part 12, the rotating part 12 is connected to the eccentric component 3;
[0057] Preferably, the output end of the drive component 2 extends into the water tank 51 and is connected to the eccentric component 3, and the elastic component 4 is connected to the side wall of the water tank 51.
[0058] Specifically, when the user places clothes into the drum body 1, the drum body 1 is under load. Under the weight of the clothes, the elastic component 4 is in an elastic deformation state. When the washing machine is started, the drive component 2, under the action of the eccentric component 3, drives the drum body 1 to make an eccentric movement. At the same time, the drum body 1 rotates under the load and eccentricity, and the centrifugal force generated causes the elastic component 4 to strain. Under the combined action of the elastic component 4 and the eccentric component 3, the drum body 1 can swing significantly, so that it can present a conical motion trajectory.
[0059] Furthermore, when the drum body 1 swings, the elastic component 4 continuously undergoes elastic deformation, and when the swing amplitude of the drum body 1 is too large, it can pull the drum body 1 back through the rotating shaft component 11, thereby achieving an adaptive dynamic balance effect, greatly improving the running stability of the drum body 1 and reducing the vibration during the operation of the washing machine.
[0060] As shown in Figures 1 to 17, in this embodiment, the eccentric component 3 and the elastic component 4 are respectively disposed at both ends of the roller assembly;
[0061] Specifically, the rotating shaft component 11 is located at one end of the drum body 1, and the rotating part 12 is located at the other end of the drum body 1;
[0062] Preferably, the washing machine is a drum-type washing machine, the drum body 1 is horizontally installed in the water tank 51, and the elastic component 4 is located between the side wall of the water tank 51 and the rotating shaft component 11, and is connected to both respectively;
[0063] The eccentric component 3 is located between the drum body 1 and the drive component 2, and the eccentric component 3 is connected to the rotating part 12 and the drive component 2 respectively;
[0064] When the washing machine is working, the drive assembly 2 operates, driving the drum body 1 to rotate circumferentially through the eccentric assembly 3 and the rotating part 12. At the same time, the drum body 1 rotates circumferentially on the elastic assembly 4 through the rotating shaft component 11. It has the advantages of simple structure, low production cost and convenient operation.
[0065] Preferably, the rotating shaft component 11 includes a rotating shaft 111 disposed on the roller body 1, a bearing 112 sleeved on the outside of the rotating shaft 111, and a bushing 113 sleeved on the outside of the bearing 112. The elastic component 4 is fixedly connected to the bushing 113. This design can ensure the normal rotation of the roller body 1 and also ensure that the elastic component 4 drives the roller body 1 to swing through the bushing 113.
[0066] As shown in Figures 1 to 17, the elastic component 4 in this embodiment includes a first soft rubber ring 41. The first soft rubber ring 41 includes a roller fixing part 411, a first deformation part 412 and a first housing fixing part 413 arranged in sequence. The roller fixing part 411 is connected to the roller assembly, and the first housing fixing part 413 is connected to the washing machine housing 5.
[0067] Specifically, the drum fixing part 411 is fixedly connected to the bushing 113, and the first housing fixing part 413 is fixedly connected to the water tank 51. When the washing machine is working, the first housing fixing part 413 is fixed on the side wall of the water tank 51 and will not move. The drum body 1 rotates in the water tank 51 through the bearing 112. At the same time, the drum body 1 drives the first deformation part 412 to continuously deform elastically through the bushing 113, so that the drum body 1 forms a swinging effect. By adopting the design of the first soft rubber ring 41, the washing machine can achieve the effect of dynamic balance by using an elastic component. The structure is simple, the production cost is low, and the maintenance cost is low.
[0068] 10. Preferably, in this embodiment, the first soft rubber ring 41 has a disc-like structure, and the roller fixing part 411, the first deformation part 412, and the first housing fixing part 413 are concentrically arranged. The roller fixing part 411 is located inside the first deformation part 412, and the first housing fixing part 413 is located outside the first deformation part 412.
[0069] This design facilitates the assembly of the first soft rubber ring 41 with the roller body 1 and the water tank 51 respectively, and provides a certain deformation space between the roller body 1 and the water tank 51 for the elastic deformation of the first deformation part 412.
[0070] Preferably, the first soft rubber ring 41 is an integrally molded structure, which has the advantages of high structural strength and long service life.
[0071] Specifically, in this embodiment, the cross-sectional shape of the first deformation part 412 is arc-shaped, preferably U-shaped. The U-shaped opening of the first deformation part 412 faces the roller body 1. The outer support of the first deformation part 412 is connected to the first housing fixing part 413, and the inner support is connected to the roller fixing part 411. With this design, when the first deformation part 412 deforms, some of the inner support of the first deformation part 412 moves closer to the corresponding outer support and some of the inner support moves away from the corresponding outer support. The first deformation part 412 drives the bushing 113 on the roller fixing part 411 to move through the inner support, so as to achieve the effect of the roller body 1 swinging.
[0072] By adopting a design where the cross-sectional shape of the first deformation part 412 is arc-shaped, the deformation of the first deformation part 412 can be ensured, thus ensuring the swing effect of the roller body 1. It can also prevent the roller body 1 from swinging too much, exceeding the deformation of the first deformation part 412, which could lead to damage to the first soft rubber ring 41 and ensure its service life.
[0073] Preferably, the elastic component 4 further includes a soft rubber cover plate 42 and a bushing fixing plate 43, wherein the soft rubber cover plate 42 is disposed on the outer side wall of the water tank 51;
[0074] Preferably, the soft rubber cover 42 is ring-shaped, and the outer wall of the water tank 51 is provided with mounting holes.
[0075] The first soft rubber ring 41 is located at the assembly hole, and the first housing fixing part 413 is sealed between the soft rubber cover plate 42 and the outer wall of the water tank 51 to ensure that the water tank 51 will not leak.
[0076] Preferably, one side of the roller fixing part 411 is an assembly groove, and the other side is formed with an assembly protrusion. One side of the bushing 113 is assembled into the assembly groove, and the two abut against each other.
[0077] The bushing fixing plate 43 is assembled on the outer side wall of the mounting protrusion, and the two abut against each other. The bushing fixing plate 43 is also provided with multiple connecting parts (such as screws), which pass through the roller fixing part 411 and are fixedly connected to the bushing 113.
[0078] As shown in Figures 1 to 17, the washing machine in this embodiment also includes a detection component 7 for detecting the swing amplitude of the drum body 1. The detection component 7 is electrically connected to the drive component 2. When the detection component 7 detects that the swing amplitude of the drum body 1 is too large, the detection component 7 will send a signal to the drive component 2 to reduce the rotation speed of the drum body 1 driven by the drive component 2 or to cut off the power and stop working, so as to avoid the washing machine vibration and abnormal noise or tipping over caused by the excessive swing amplitude of the drum body 1, thereby improving the safety performance of the washing machine.
[0079] Preferably, the detection component 7 includes a tactile switch 71 and a trigger protrusion 72. The soft rubber cover plate 42 is provided with an assembly part for assembling the tactile switch 71. The trigger protrusion 72 is located on one side of the bushing fixing plate 43. The first deformation part 412 elastically deforms, and the bushing fixing plate 43 on the roller fixing part 411 also moves with the elastic deformation of the first deformation part 412. When the swing amplitude of the roller body 1 is too large, the bushing fixing plate 43 drives the side wall of the trigger protrusion 72 to touch the tactile switch 71, so that the tactile switch 71 sends a signal to the drive component 2.
[0080] When the swing amplitude of the roller body 1 is within a suitable range, the side wall of the trigger protrusion 72 will not touch the tactile switch 71.
[0081] As shown in Figures 1 to 17, the washing machine in this embodiment also includes a counterweight 8. The counterweight 8 is disposed in the assembly cavity 53 and located near the elastic component 4. Since the area of the drum body 1 near the elastic component 4 is a region with a large swing amplitude, by setting a counterweight 8 near this region, it can play a dual role in vibration reduction with the dynamic balancing device, helping the dynamic balancing device to balance and stabilize the washing machine, reducing the shaking and swaying of the washing machine when it rotates at high speed, preventing the machine from moving or tilting, thereby maintaining the stability of the washing machine.
[0082] Furthermore, the presence of counterweights and dynamic balancing devices can absorb some of the vibration energy generated by the internal operation of the washing machine, reducing the vibration and noise levels transmitted to the outside of the washing machine.
[0083] By incorporating counterweights and dynamic balancing devices, the washing machine can operate more stably, preventing clothes from becoming disorganized due to vibration. This helps improve the washing effect, ensuring clothes are cleaned more evenly by water and detergent, and reduces friction and vibration of washing machine parts. Consequently, it reduces wear and tear on the machine, extending its lifespan and minimizing the need for repairs and parts replacements.
[0084] Preferably, the counterweight 8 can be made of rubber or metal. Rubber has high density and good elasticity, which allows it to provide weight and stability to a certain extent, and also has a certain vibration damping effect. Rubber materials can effectively absorb vibrations and noise generated inside the washing machine, reducing the impact transmitted to the outside of the washing machine.
[0085] Metals, with their high density and stability, provide good balance and stability, while effectively absorbing vibrations and reducing noise. Iron and lead are commonly used metals; their appropriate weight and strength allow them to act as counterweights inside washing machines.
[0086] Preferably, the bottom of the counterweight 8 abuts against the inner wall of the outer shell 52, and the curvature of the two is similar or the same. The top of the counterweight 8 is provided with a groove for accommodating the water tank 51. The groove abuts against the bottom of the water tank, and the curvature of the two is similar or the same. The length of the counterweight 8 is greater than half the length of the water tank 51 to ensure the stabilizing effect of the counterweight 8.
[0087] As shown in Figures 1 to 17, the eccentric component 3 in this embodiment includes a component located at the output end of the drive component 2.
[0088] The roller body 1 has a second soft rubber ring 31 and a rotating housing 32 sleeved on the outside of the second soft rubber ring 31. The rotating housing 32 is fixedly connected to the roller assembly, and the second soft rubber ring 31 is fixedly connected to the output end of the drive assembly 2. Specifically, the rotating housing 32 is fixedly connected to the rotating part 12. The rotating part 12 is an assembly hole provided on one end of the roller body 1. One end of the rotating housing 32 is fixed on the rotating part 12. The two are integrally formed structures, which have the advantages of high structural strength and long service life.
[0089] Preferably, the other end of the rotating housing 32 extends into the drum body 1, making the structure of the washing machine more compact and effectively reducing its size. Furthermore, during operation, the rotating housing 32 also acts as agitator, breaking up clothes and preventing them from tangling. Preferably, the second soft rubber ring 31 has multiple positioning slots 314, and the output end of the drive assembly has multiple positioning protrusions 231 corresponding to the positioning slots 314. The positioning protrusions 231 engage with the positioning slots 314, thus fixing the second soft rubber ring 31 to the output end of the drive assembly 2.
[0090] Specifically, when the output end of the drive component 2 rotates circumferentially, the second soft rubber ring 31 drives the rotating housing 32 to rotate circumferentially.
[0091] Specifically, under load inside the drum body 1, the drum body 1 can press the second soft rubber ring 31 against the rotating housing 32, causing it to elastically deform. This changes the position of the rotating housing 32 at the output end of the drive assembly, causing the position of the drum body 1 to shift within the water tank 51. When the drum body 1 is driven to rotate circumferentially, the second soft rubber ring 31 continuously undergoes elastic deformation under the weight of the rotating housing 32 and the clothes inside the drum body 1. Because the second soft rubber ring 31 is located at the output end, even a slight deformation of the second soft rubber ring 31 will cause the drum body 1 to produce an eccentric effect, which has the advantage of simple structure.
[0092] Preferably, in this embodiment, the second soft rubber ring 31 includes a second deformable part 311, an output end connection part 312 concentrically disposed inside the second deformable part 311, and a second housing fixing part 313 concentrically disposed outside the second deformable part 311. The output end connection part 312 is connected to the output end of the drive assembly 2, and the second housing fixing part 313 is fixedly connected to the rotating housing 32.
[0093] Specifically, the output end connection part 312 has a through hole, the output end connection part 312 is sleeved on the outside of the output end of the drive assembly 2, the positioning slot 314 is provided on the side of the second deformation part 311 facing the drive assembly 2, a deformation groove 315 is formed on the other side of the second deformation part 311, the second housing fixing part 313 is fixedly connected to the front end of the rotating housing 32, and the deformation groove 315 is located near the front end of the rotating housing 32;
[0094] The front end of the rotating housing 32 can press the second soft rubber ring 31, causing it to elastically deform. This causes a portion of the second housing fixing part 313 to move closer to the output end connection part 312, reducing the gap in the deformation groove 315. During rotation, the portion of the second housing fixing part 313 continuously moves closer to the output end connection part 312, reducing the gap in the deformation groove 315, while the portion of the second housing fixing part 313 continuously moves away from the output end connection part 312, increasing the gap in the deformation groove 315. This achieves an eccentric effect. By adopting the design of the second soft rubber ring 31, the washing machine can achieve the effect of driving the drum body to rotate eccentrically using only one elastic component. The structure is simple, the production cost is low, and the maintenance cost is low.
[0095] As shown in Figures 1 to 17, the eccentric component 3 in this embodiment also includes a soft rubber fixing ring 33. The soft rubber fixing ring 33 is disposed inside the rotating housing 32 and can be used to fix the second housing fixing part 313 inside the rotating housing 32. A connecting member 35 is also provided between the soft rubber fixing ring 33 and the rotating housing 32, and the two are detachably connected through the connecting member 35. The second housing fixing part 313 is also provided with a clearance hole or clearance gap that can avoid the connecting member 35.
[0096] Preferably, the connecting member 35 includes a connecting post and a connecting screw. The connecting post is disposed inside the rotating housing 32. The soft rubber retaining ring 33 is assembled on the free end of the connecting post. Then, the connecting screw passes through the soft rubber retaining ring 33 and is threadedly connected to the connecting post, so that the soft rubber retaining ring 33 and the second soft rubber ring 31 are assembled inside the rotating housing 32. This has the advantages of simple structure, convenient operation, and easy maintenance of the second soft rubber ring 31.
[0097] Preferably, the drive assembly 2 includes a motor bracket 21 and a drive motor 22. The drive motor 22 is provided with an output shaft 23. The outer wall of the water tank 51 is provided with an assembly hole. The motor bracket 21 is sealed at the assembly hole. The motor bracket 21 extends into the water tank 51, and part of the motor bracket 21 extends into the rotating housing 32. Part of the drive motor 22 is provided inside the motor bracket 21. The output shaft 23 passes through the motor bracket 21 and extends to the second soft rubber ring 31. A motor coupling sleeve is fixed on the outer wall of the output shaft 23. The positioning protrusion 231 is provided on the motor coupling sleeve.
