Description

The present invention belongs to the technical field of washing machines, and more specifically, to a speed reduction clutch device for washing machines and a washing machine.

As a household appliance, washing machines have become an integral part of people's lives. Also, fully automatic pulsator washing machines are becoming more and more popular as the main washing machine type. In the operation method of the conventional fully automatic pulsator washing machine, the driving device normally rotates the pulsator of the washing machine forward and backward through the deceleration clutch device during washing and rinsing. Further, during dehydration, the driving device synchronously drives the pulsator and the inner tub of the washing machine through the deceleration clutch device to rotate at high speed.

However, with the rapid development of science and technology, washing methods that simply use a pulsator to agitate the water flow, such as the conventional fully automatic pulsator washing machine, are gradually becoming limited in improving the washing effect of clothes. there is Therefore, how to increase the variety of washing of the fully automatic pulsator washing machine and how to improve the washing effect is a technical problem to be solved as soon as possible.

Several patents currently propose solutions to this problem. For example, there is US Pat. do. That patent discloses a transmission mechanism that produces a two-way drive suitable for use in washing machines. The mechanism includes a power input and two power outputs. Among them, one power output end is connected to the stirrer shaft (10) to rotate the stirrer shaft in the first direction. The other power output end is connected to the inner tub shaft (11) to rotate the inner tub shaft in a second direction opposite to the first direction. In addition, regarding a washing machine that generates two-way washing, a washing method that enables two-way washing to occur in the washing machine, and an agitator and an inner tub used in the washing machine, the patent discloses that two-way driving is generated in the washing machine. It discloses a transmission mechanism that enables. In addition, the specification discloses a specific structure of the transmission mechanism. As can be seen from the description and drawings, this patent somewhat solves the problem that the conventional fully automatic pulsator washing machine has a single power drive system for washing. However, the transmission mechanism disclosed here has problems such as a complicated structure, high difficulty in manufacturing and mounting, and high manufacturing cost.

In addition, most of the reduction clutch devices in conventional pulsator washing machines have a one-way bearing between the output bush and the brake wheel. Therefore, when the soft cleaning program is executed, the inner tub and the pulsator can only rotate clockwise at the same speed and in the same direction, or rotate counterclockwise at the same speed and in the same direction. That is, since it can only rotate in one direction, the effect of washing clothes is significantly reduced.

In view of the above, the present invention is proposed.

The brake wheel axle 2 is arranged outside the input shaft 1 and fixed to the open end of the brake wheel 17 so that one end thereof is closed. The first fixed shaft gear train and the second fixed shaft gear train are respectively installed in the inner space of the braking wheel 17 , and the first fixed shaft gear frame 6 of the first fixed shaft gear train is mounted on the braking wheel shaft 2 or the braking wheel 17 . fixed to

Preferably, the second fixed shaft gear frame 12 of the second fixed shaft gear train is fixed to the first fixed shaft gear frame 6 or the braking wheel axle 2 or the braking wheel 17 .

The speed reduction clutch device for a washing machine of this embodiment further includes a clutch mechanism for controlling switching between independent rotation of the input shaft and synchronous rotation of the input shaft and the braking wheel shaft. A clutch mechanism provides relative reverse rotation of the output shaft and output bushing, thereby enabling dual power cleaning operation. A soft washing operation is performed by rotating at the same speed and in the same direction at a low speed, and a dewatering operation is performed by rotating at the same speed and in the same direction at a high speed.

When the clutch mechanism controls the input shaft 1 to rotate independently, the input shaft 1 transmits power to the first shaft fixed gear train. The first shaft fixed gear train outputs power to the output shaft 22, which simultaneously transmits power to the second shaft fixed gear train. Then, the output shaft 22 and the output bushing 21 rotate in opposite directions because the second shaft fixed gear train outputs power to the output bushing 21 .

When the clutch mechanism controls the input shaft 1 and the brake wheel axle 2 to rotate synchronously, the input shaft 1 and the brake axle 2 are connected to the brake wheel 17, the internal first axle fixed gear train and the second axle fixed gear train. To synchronously rotate gear trains. As a result, the output shaft 22 and the output bushing 21 rotate in the same direction at the same speed.

The speed reducer described in this embodiment is constructed by connecting two fixed shaft gear trains, a first fixed shaft gear train I and a second fixed shaft gear train II. When the rotational speed is input from the input shaft, the rotational speed is reduced by the first shaft fixed gear train I and then output from the output shaft to operate the pulsator of the washing machine. At the same time, the output shaft also transmits power to the second fixed gear train II. The rotational speed is reduced by the second shaft fixed gear train II and then output from the output bush to operate the inner tub of the washing machine. Thus, for one power input, after deceleration, two power outputs from the output shaft and the output bushing in two directions and with a constant transmission ratio are realized, thereby realizing the double driving function of the washing machine.

The washing machine speed reduction clutch device of the present invention has a rational structural arrangement. The speed reducer consists of two axially fixed gear trains. The two shaft-fixed gear trains respectively reduce and transmit power, and output two powers from the output shaft and the output bush. As a result, the reduction ratio, the rotation of the output shaft and the output bushing in relatively opposite directions with a constant transmission ratio, and the load capacity are satisfied. Eliminates shortcomings such as

This embodiment further provides a washing machine including a washing tub, a pulsator and a speed reduction clutch device. The reduction clutch device is connected to an input shaft, a first fixed shaft gear train including a first ring gear, a second fixed shaft gear train, and the first ring gear, and is capable of transmission to a second fixed shaft gear train. and an output bushing disposed on the output shaft and connected to the second shaft fixed gear train.

In the washing machine of this embodiment, the rotary motor can operate the output shaft and the output bush through the speed reduction clutch device during washing, thereby achieving dual power driving to improve the washing effect. During dehydration, the rotary motor operates the output shaft and the output bushing at the same speed in the same direction through the reduction clutch device, thereby performing the soft washing operation or the dewatering operation.

1 to 7, this embodiment discloses a speed reduction clutch device for a washing machine. The deceleration clutch device includes an input shaft 1, a brake wheel having an open inner space inside, and a brake disposed outside the input shaft 1 and fixed to the open end of the brake wheel so that one end is closed. The wheelset 2, the gear train installed in the inner space of the braking wheel, and the braking wheelset 2 alone are locked to allow the input shaft 1 to rotate independently, or the braking wheelset 2 is released to release the braking wheelset 2 and the input shaft. 1 to synchronously rotate the input shaft 1 and the braking wheel 17.

In this embodiment, the clutch mechanism locks the braking wheel set 2 so that the braking wheel 17 does not rotate together with the input shaft 1 . At this time, the washing machine performs a normal washing process. On the other hand, when dehydration is required, the clutch mechanism releases the brake wheelset 2 and connects the brake wheelset 2 and the input shaft 1, thereby allowing the brake wheelset 2 and the brake wheel to move as the input shaft 1 rotates. Rotate together.

The clutch mechanism includes a torque transmission bushing 33, a connecting plate 3 and a positioning plate 4. The torque transmission bush 33 is arranged on the input shaft 1 and rotates together with the input shaft 1 . The positioning plate 4 is arranged outside the braking wheel axle 2 and fixed in position. The connection plate 3 is arranged on the brake wheel axle 2, positioned between the torque transmission bush 33 and the positioning plate 4, and is slidable only in the axial direction. When the connection plate 3 slides toward the positioning plate 4 and is connected to the positioning plate 4, the positioning plate 4 locks the brake wheel axle 2 via the connection plate 3, so that the input shaft 1 can rotate independently. move. Further, when the connection plate 3 slides toward the torque transmission bush 33 and is connected to the torque transmission bush 33 , the torque transmission bush 33 interlocks with the brake wheelset 2 via the connection plate 3 , so that the input shaft 1 and the braking wheel shaft 2 rotate synchronously. The connection plate 3 includes a connection hole, and an inner spline is provided on the inner wall of the connection hole. Further, the braking wheel axle 2 is provided with an outer spline, and the connection plate 3 and the braking wheel axle 2 are spline-connected. When the connection plate 3 slides toward the positioning plate 4 and is connected to the positioning plate 4, the positioning plate 4 restricts the rotation of the connection plate 3 in the circumferential direction, thereby locking the braking wheel axle 2. do. Further, when the positioning plate 4 slides toward the torque transmission bush 33 and is connected to the torque transmission bush 33, the torque transmission bush 33 interlocks with the connection plate 3 in the circumferential direction. As a result, the torque transmission bushing 33 rotates the braking wheelset 2 via the connection plate 3 .

Since the braking wheel axle 2 and the connecting plate 3 are connected by a spline, the braking wheel and the connecting plate rotate integrally in the circumferential direction. Also, the connection plate 3 is slidable along the axial direction of the braking wheel axle 2 . When the connecting plate 3 is slid to one side and connected to the positioning plate 4, the positioning plate 4 and the connecting plate 3 are integrated in the circumferential direction. Since the position of the positioning plate 4 is fixed, the connecting plate 3 is locked in position in the circumferential direction, so that the braking wheel axle 2 is likewise locked and cannot rotate. At this time, even if the input shaft 1 rotates, the braking wheel shaft 2 and the braking wheel do not rotate together, and the fixed position is maintained. Further, when the connection plate 3 slides to the other side and is connected to the torque transmission bush 33, the torque transmission bush 33 and the connection plate 3 interlock in the circumferential direction. Therefore, when the input shaft 1 rotates, the torque transmission bush 33 rotates integrally, and the connection plate 3, the braking wheel axle 2, and the braking wheel also rotate integrally.

Both ends of the connection plate 3 are provided with meshing teeth that mesh with the torque transmission bushing 33 and the positioning plate 4, respectively. When the connection plate 3 slides toward the positioning plate 4, the connection plate 3 and the positioning plate 4 mesh with each other, and the positioning plate 4 restricts the rotation of the connection plate 3 in the circumferential direction. Further, when the connection plate 3 slides toward the torque transmission bush 33 and meshes with the torque transmission bush 33, the torque transmission bush 33, the connection plate 3 and the brake wheelset 2 are interlocked in the rotational direction. In this solution, the state switching is realized by the meshing teeth, so the switching process is quick and stable.

Said connection plate 3 includes an upper annular body and a lower annular body connected and coaxially installed at the bottom of the upper annular body. The diameter of the upper annulus is greater than the diameter of the lower annulus. In addition, meshing teeth that mesh with the positioning plate 4 are provided around one end of the upper annular body that is spaced apart from the lower annular body. In addition, meshing teeth that mesh with the meshing teeth of the torque transmission bush 33 are provided around one end of the lower annular body that is spaced apart from the upper annular body. The connection plate 3 is arranged outside the brake wheelset 2 and the torque transmission bush 33 is arranged on the input shaft 1 . Therefore, the size of the connection plate 3 is larger than the torque transmission bush 33 . On the other hand, the meshing teeth on both ends of the connection plate 3 need to be arranged according to the members to be meshed. Therefore, in the present invention, the connection plate 3 is installed as an upper annular body and a lower annular body. Since the diameter of the upper annular body is large, meshing teeth to be combined with the positioning plate 4 are installed. Due to this structural design, the state-switching process of the clutch mechanism becomes more stable.

Preferably, the reduction clutch device includes an outer casing that is fixed to the washing tub of the washing machine. The braking wheel is mounted within the outer casing and the positioning plate 4 is fixedly mounted on the outer casing. Since the outer casing is directly fixed to the outer tub of the washing tub of the washing machine, the outer casing and the outer tub of the washing machine are integrally fixed. Further, since the positioning plate 4 is mounted on the outer casing, its position is fixed.

The outer casing includes an upper case 20 and a lower case 26 . The upper end case is fixed to the washing tank. A third rolling bearing 19 is mounted in the bearing housing of the upper end case 20 . The lower end case is mounted on the upper end case to form a space for receiving a braking wheel between the upper end case and the lower end case. A mounting hole is formed in the bottom of the lower end case. The positioning plate 4 includes a circular through groove. The positioning plate 4 is mounted so as to cover the bottom of the lower end case, and the circular through groove is coaxial with the mounting hole. The brake wheel axle 2 passes through the mounting hole and the circular through groove in order from the inside to the outside of the space. Since the positioning plate 4 is mounted so as to cover the bottom of the lower end case, it is convenient to engage and lock the connecting plate 3 .

A bearing housing 262 protrudes from the bottom of the lower end case 26 . A first rolling bearing 5 is mounted in the bearing housing 262 of the lower end case 26 . The brake wheel is installed to pass through the bearing housing 262 . The positioning plate 4 is arranged outside the bearing housing. Also, the circular through groove of the positioning plate 4 is coaxial with the bearing housing. Engagement teeth are provided around the circular through groove. When the connecting plate 3 slides toward the bearing housing, the meshing teeth on the top of the connecting plate 3 mesh with the meshing teeth provided around the circular through groove.

The bottom case 26 includes a cylindrical side peripheral wall 261 . One end of the side peripheral wall is an open end, and the other end converges toward the center to form an annular bottom wall. The bearing housing 261 includes a bush portion projecting outward from the inner edge of the annular bottom wall. A bent side that bends toward the center is provided on the outer edge of the bush portion. The bent side is used to regulate the mounting position of the bearing. Said positioning plate 4 comprises an annular body, the inner edge of which protrudes to one side to form a sleeve portion. A terminal end of the sleeve portion is bent toward the center to form an annular side, and a gear is provided around the annular side. The annular body is tightly connected to the annular bottom wall. The sleeve portion is disposed on the bush portion, and the annular side covers the bent side.

In the above scheme, the entire circumference of the annular body of the positioning plate 4 is fixed to the annular bottom wall of the lower end case 26 by a tightening member, so that the structures of the positioning plate 4 and the lower end case are integrated.

1 to 7, based on the second embodiment, the present embodiment further provides a speed reduction clutch device for a washing machine. In the second embodiment, the clutch mechanism will be explained in more detail.

Specifically, the clutch mechanism includes a connecting plate 3 and a drive member. The connection plate 3 has a first position where the brake wheel axle 2 is locked and the input shaft 1 can be rotated independently, and a second position where the brake wheel is released and the brake wheel and the input shaft 1 are connected and they are interlocked. It has 2 positions. Said drive member moves said connecting plate 3 between said first and second positions.

In the above scheme, the driving member of the clutch mechanism can switch between the independent rotation of the input shaft 1 and the synchronous rotation of the input shaft 1 and the braking wheels by moving the connecting plate 3 . This embodiment has a simple structure, rational design, and stable mechanical performance.

The clutch mechanism includes shift forks 28 . A shift fork 28 extends to the drive member at one end and to the connection plate 3 at the other end. The drive member moves one end of the shift fork 28 up and down, and the other end of the shift fork 28 moves the connecting plate 3 between the first position and the second position.

Preferably, the central portion of the shift fork 28 is rotatably attached to the shift fork holder 41 . The drive member also includes a rotary motor 24 . A rotary pushing member 25 is connected to the output shaft of the rotary motor 24 . The rotary pushing member 25 is provided with a pushing portion, and one end of the shift fork 28 contacts the pushing portion. When the rotary motor 24 rotates the rotary pushing member, the pushing portion of the rotary pushing member rotates and pushes the corresponding one end of the shift fork 28 to move up and down. This causes the other end of the shift fork 28 to move the connecting plate 3 between the first and second positions. In this method, the connecting plate 3 can be moved by providing a pushing portion on the rotary pushing member and rotating the pushing portion by rotating the rotary pushing member. The structure of this driving scheme is simple and sophisticated, and the energy consumption is small.

Further, one end of the shift fork 28 maintains contact with the pushing portion. As a principle of realization, it may be realized by connecting the shift fork 28 to the return spring, or may be realized by other structure. Specifically, it will be described in detail below.

The rotary pushing member includes a cylindrical body 251 . One end of the cylindrical body 251 is connected to the drive shaft of the rotary motor 24, and the other end of the cylindrical body is provided with the pushing portion. The pushing portion has a spiral surface 2521 extending in the circumferential direction of the cylindrical body. When the cylindrical body rotates, the helical surface 2521 rotates and pushes the corresponding end of the shift fork 28 to move up and down. This causes the other end of the shift fork 28 to move the connecting plate 3 between the first and second positions.

Specifically, the pushing part includes a ridge 252 extending in the circumferential direction from the edge of the circular surface at one end of the cylindrical body. A gap is provided between the head and tail of the protrusion 252 . In the extending direction from one end of the protrusion to the other end, the upper surface of the protrusion gradually rises from the circular surface, reaches the highest position, and then gradually descends to the circular surface to form a spiral surface 2521. It is molded like this. A spherical boss 282 is provided at the corresponding end of the shift fork 28, and the spherical boss 282 contacts and cooperates with the helical surface. Furthermore, the ridges are designed to have a symmetrical structure. As a result, the state of the washing machine is switched once each time the rotary motor 24 rotates the cylindrical body by 180°. For example, when the initial position is the gap between the head and tail of the ridge, when the rotary motor 24 rotates the cylindrical body 180°, the ridge pushes one end of the shift fork 28 to rotate downward. The other end of 28 moves the connecting plate 3 upward so that the connecting plate 3 meshes with the positioning plate 4 . At this time, the washing machine can perform the washing process. On the other hand, when dehydration process/soft cleaning is desired, the rotary motor 24 continues to rotate the cylindrical body by 180°. Then, one end of the shift fork 28 that cooperates with the push-up portion returns upward, and the other end of the shift fork 28 moves the connection plate 3 downward to mesh with the torque transmission bush 33 . At this time, the input shaft 1 integrally rotates the brake wheel to perform dehydration or soft cleaning. It should be noted that the washing machine includes a drive motor 32 whose output end is connected to said input shaft 1 . The washing machine performs the dehydration process or the soft washing by controlling the rotation of the drive motor 32. The main difference between them is the rotation speed and the rotation direction.

The rotary motor 24 and the rotary pressing member are installed in order from top to bottom. The upper portion of the rotary pushing member is drivably connected to the rotary motor 24, and the pushing portion is provided at the bottom portion of the rotary pushing member. One end of the shift fork 28 corresponding to the pushing portion is bent and extended upward, and a spherical boss at the end contacts the helical surface of the pushing portion.

A speed reduction clutch device for a washing machine includes a speed reducer large panel (see top cover 20 of Embodiment 1) that is mounted in the washing tub of the washing machine. The decelerator large panel includes a first mounting portion and a second mounting portion that are installed adjacent to each other. The braking wheel is mounted on the first mounting portion, and the driving member is mounted on the second mounting portion. One end of the shift fork 28 extends to the second mounting portion and contacts the driving end of the driving member.

In another parallel embodiment, the central portion of the shift fork 28 is pivotally mounted on a shift fork holder 41 . The drive member includes a traction motor. A traction motor is connected to one end of the shift fork 28 via a traction cable. The shift fork 28 is rotated by the traction motor withdrawing/releasing the traction cable. And thereby, the other end of the shift fork 28 moves the connection plate 3 between the first position and the second position.

The clutch mechanism includes torque transmission bushings 33 and positioning plates 4 . The torque transmission bush 33 is arranged on the input shaft 1 and rotates together with the input shaft 1 . The positioning plate 4 is arranged outside the braking wheel axle 2 and fixed in position. The connection plate 3 is arranged on the brake wheel axle 2, positioned between the torque transmission bush 33 and the positioning plate 4, and is slidable only in the axial direction. A shift fork holder 41 protrudes from the positioning plate 4, and the central portion of the shift fork 28 is rotatably attached to the shift fork holder 41. As shown in FIG. A shift fork 28 extends to the drive member at one end and to the connection plate 3 at the other end.

Preferably, the connecting plate 3 is provided with an annular boss, and one end of the shift fork 28 extending to the connecting plate 3 is provided with a semi-annular clamp. The shift fork 28 clamps the annular boss by the semi-annular clamping portion 281 .

In the above scheme, the holding portion 281 of the shift fork 28 holds the annular boss of the connection plate 3, so that the connection plate 3 can be easily moved up and down.

In addition, in this embodiment, one end of the shift fork 28 must maintain contact with the pushing portion. As a principle of realization, it may be realized by connecting the shift fork 28 to the return spring, or may be realized by pushing with the connection plate 3 . Specifically, a spring 30 is compressed and arranged between the connection plate 3 and the positioning plate 4/lower end case. Alternatively, a spring cap 29 is attached to the positioning plate or the lower end case, and the upper end of the spring 30 contacts the spring cap. Also, the bottom end of the spring contacts the connection plate and pushes the connection plate downward. The connection plate 3 has a downward biasing force due to the action of the spring 30 . On the one hand, one end of the shift fork 28 abuts against the pushing part and the other end acts on the connecting plate 3 concerned. In a normal state, one end of the shift fork 28 that cooperates with the connection plate moves downward under the action of the spring 30 and engages with the torque transmission bush 33 . On the other hand, the other end of the shift fork moves upward and comes into contact with the bottom end of the protrusion of the pushing portion. At this time, the input shaft 1 of the washing machine can only rotate independently, and the washing machine performs the washing process.

When the rotary motor 24 rotates the cylindrical body by 180°, the end of the shift fork 28 is pushed by the protrusion 252 and moves downward. Then, the other end of the shift fork 28 pushes the connection plate 3 upward, and the connection plate 3 moves the compression spring 30 upward by the action of the pushing portion to mesh with the positioning plate 4 . At this time, the input shaft 1 and the brake wheel 17 are interlocked so that the washing machine can perform dehydration or soft washing.

1 to 3 and 8 to 10, in this embodiment, mainly, a specific cooperation system between the output bushing and the brake wheel in the first to third embodiments will be described in detail.

This embodiment provides a speed reduction clutch device for a washing machine including a speed reduction mechanism. The speed reduction mechanism is connected to the input shaft 1, a first fixed shaft gear train including a first ring gear, a second fixed shaft gear train, and the first ring gear, and can be transmitted to a second fixed shaft gear train. an output shaft 22 connected to the output shaft 22 to operate the inner tank, an output bush 21 connected to the second shaft fixed gear train, the first shaft fixed gear train and the second shaft It includes a braking wheel 17 in which a fixed gear train is located. A second rolling bearing 18 is mounted between the braking wheel 17 and the output bushing 22 .

The speed reduction clutch device for a washing machine of this embodiment reduces power input from an input shaft 1 by means of two fixed shaft gear trains, namely, a first fixed shaft gear train and a second fixed shaft gear train. Assign to output bush 21 . A simple and stable fixed shaft gear train can achieve the effect of two power outputs for one power input.

Therefore, when the speed reduction clutch device for a washing machine of this embodiment is applied to a washing machine, it can realize two power outputs from the output shaft 22 and the output bushing 21 during the washing/rinsing process of the washing machine. . When the two rotating directions of the output shaft 22 and the output bushing 21 are relatively opposite, the inner tub and the pulsator move in relatively opposite directions, thereby realizing a dual power cleaning effect. As a result, the variety of washing water flows is increased, and the washing effect is improved. Further, when the output shaft 22 and the output bush 21 rotate at the same speed in the same direction, the inner tub and the pulsator rotate at the same speed in the same direction, so that the soft washing effect with less friction on the clothes can be obtained. Realized.

For garments that are prone to damage from kneading, a soft wash program should be used. In this embodiment, by using the rotating tank bearing 100 installed between the output bushing 21 and the brake wheel 17 instead of the conventional one-way bearing, the inner tank and the pulsator rotate clockwise in the same direction, or , to enable counterclockwise rotation in the same direction. It is also possible to control the inner tank and the pulsator to alternately rotate clockwise and counterclockwise in the same direction at the same speed. This not only reduces the friction of the clothes, but also makes it possible to form a more diversified water flow, thereby improving the cleaning rate of the clothes and guaranteeing the washing effect of the clothes.

Specifically, the braking wheel 17 has an open inner space. Further, the brake wheel 17 has a hollow columnar structure. The columnar braking wheel 17 is open at one end and closed at the other end. The first fixed shaft gear train and the second fixed shaft gear train are located in the space of the braking wheel 17 . The open end is fixedly connected to a brake wheel axle 2 arranged outside the input shaft 1 . An opening 171 is provided at the closed end of the braking wheel 17 near the output shaft 22 . The output shaft 22 and the output bush 21 are connected to the pulsator and inner tub of the washing machine through the opening 171 of the braking wheel 17, respectively. The opening 171 has a circular shape and extends outward to form a hollow cylindrical bearing housing 172 for mounting the second rolling bearing 18 . The second rolling bearing 18 is mounted inside the bearing housing 172 . The output bushing 21 is operably connected to the braking wheel 17 through cooperation with the second rolling bearing 18 . The bearing housing 172 may be configured to be installed independently on the brake wheel 17. However, by forming the bearing housing 172 and the brake wheel 17 into an integrated structure, production processing is facilitated and mounting steps are simplified. become. In addition, the stability between them is enhanced, and phenomena such as loosening are less likely to occur even after long-term use.

Further, the second rolling bearing 18 includes an inner ring, an outer ring, and rolling elements installed between the inner ring and the outer ring. The inner ring is connected to the output bushing 21 and rotates along with the output bushing 21 . The outer ring of the second rolling bearing 18 is linked and fixedly connected to the bearing housing 172 to provide support. The second rolling bearing 18 used can not only realize clockwise rotation in the same direction at the same speed of the inner tank and the pulsator, but also realize counterclockwise rotation in the same direction at the same speed. . Also, since the sliding friction between the brake wheel 17 and the output bushing 21 is changed to rolling friction, friction loss is reduced and the life of the deceleration clutch device and the washing machine is extended.

Further, a bearing mounting portion 211 is installed on the output bush 21, and the bearing mounting portion 211 and the second rolling bearing 18 are mounted so as to cooperate with each other. Preferably, the bearing mounting portion 211 is formed by extending the end portion of the output bushing 21 closer to the braking wheel 17 to the outside. The bearing mounting portion 211 and the output bushing 21 are integrally installed. This simplifies the structure and simplifies the installation steps, thus improving the efficiency of production and installation. Also, the performance of the mechanical structure is stabilized.

In the above scheme, the outer diameter of the bearing mounting part 211 is larger than the inner diameter of the inner ring of the second rolling bearing 18, and the output bush 21 and the second rolling bearing 18 are tightly fitted. At the time of mounting, shrink fitting or press fitting may be used, and the surface of the second rolling bearing 18 is used as a reference. Therefore, a hole-based interference fit is provided between the inner ring and the bearing mounting portion 211 . However, in order to facilitate removal of the bearing, the fit tolerance should not be too large, eg H7/k6. Similarly, the second rolling bearing 18 and the bearing housing 172 are also linked by an interference fit. The inner diameter of the bearing housing 172 is smaller than the outer diameter of the second rolling bearing 18, and it may be mounted by shrink fitting or press fitting. This makes it possible to ensure a close cooperation between the rolling bearing 100 and the bearing housing 172 . Otherwise, damage to the bearings and bearing housing 172 would be much greater by subjecting the bearings and bearing housing 172 to pulsating and fluctuating stresses during vibration. Further, if a clearance fit is used, the shaft will also vibrate, and the shaft will receive symmetrical repetitive fluctuating stress and impact. This further increases the damage to the shaft and components on the shaft.

Preferably, the outer edge of the bearing housing 172 is provided with a bent edge that bends toward the center. The bent side is used to restrict the mounting position of the second rolling bearing 18, thereby preventing the bearing from jumping or the like during the vibration process of the washing machine.

Furthermore, the diameter of the output bushing 21 and the diameter of the bearing mounting portion 211 are different. The outer diameter of the output bushing 21 is larger than the outer diameter of the bearing mounting portion 211 . As a result, it is possible to prevent the normal use of the washing machine from being affected by the displacement between the second rolling bearing 18 and the output bushing 21 due to the action of an external force during use.

Specifically, the output bushing 21 and the bearing mounting portion 211 are transitioned via a transition ramp portion 213 and connected. The bearing mounting portion 211 is formed by extending the end portion of the output bushing 21 while being inclined inward and then horizontally extending outward.

Preferably, the outer peripheral wall of said transition ramp 213 is circumferentially provided with several threads. This prevents a situation in which normal use is affected due to displacement or jumping between the second rolling bearing 18 and the bearing mounting portion 211 due to the action of an external force during use.

In this embodiment, the second fixed shaft gear train comprises a fixed second fixed shaft gear frame 12 and a second fixed shaft gear group 23 rotatably mounted on the second fixed shaft gear frame 12. include. Also, the length of the bearing mounting portion 211 is greater than the thickness of the second rolling bearing 18 . The outer wall of the end of the bearing mounting portion 211 protruding from the second rolling bearing 18 is provided with an insertion tooth groove 212 that is connected to the second shaft fixed gear group 23 so as to cooperate therewith. A disk-shaped connection flange 214 is provided at the end of the output bushing 21 that is spaced apart from the brake wheel 17 . The connection flange 214 is provided with several connection holes, and the connection holes of the connection flange 214 are used to connect with the inner tank, thereby realizing rotation of the inner tank.

The present embodiment further provides a washing machine utilizing the speed reduction clutch device described above. The washing machine includes an inner tub, a pulsator and a reduction clutch device. The reduction clutch device is connected to the input shaft 1, a first fixed shaft gear train including a first ring gear, a second fixed shaft gear train, and the first ring gear, and is capable of transmission to a second fixed shaft gear train. an output shaft 22 connected to the output shaft 22 to operate the inner tank, an output bush 21 connected to the second shaft fixed gear train, the first shaft fixed gear train and the second shaft It includes a braking wheel 17 in which a fixed gear train is located. A second rolling bearing 18 is mounted between the braking wheel 17 and the output bushing 22 .

In this embodiment, a method of connecting the first fixed shaft gear frame 6 and the second fixed shaft gear frame 12 in the first embodiment will be described.

As shown in FIGS. 1-3 and 11-14, the reduction clutch device provided herein includes a brake wheel 17 and a brake wheelset 2. As shown in FIGS. The braking wheel 17 has an open internal space inside. The brake wheel axle 2 is arranged outside the input shaft 1 and fixed to the open end of the brake wheel 17 so that one end thereof is closed. The first fixed shaft gear train and the second fixed shaft gear train are installed in the inner space of the brake wheel 17, respectively. The first axle-fixed gear frame 6 is fixed to the brake wheel axle 2 or the brake wheel 17 , and the second axle-fixed gear frame 12 is fixed to the first axle-fixed gear frame 6 .

Preferably, as shown in FIG. 13, the braking wheel axle 2 includes a bush portion arranged outside the input shaft and an end cover portion closing the open end of the braking wheel. The first axle-fixed gear frame 6 is fixed to the end cover of the brake wheel axle 2 , and the second axle-fixed gear frame 12 is fixedly connected to the first axle-fixed gear frame 6 .

This embodiment provides a control method for a washing machine. Specifically, it includes a state in which the inner tub and the pulsator are relatively stationary during rotation during the washing process of the washing machine.

The washing machine of this embodiment is equipped with a pulsator, and the inner tub serves as a washing tub. The inner tank may be an inner tank with holes or an inner tank without holes. A pulsator is installed at the bottom of the inner tank. In a washing machine, a pulsator rotates to create a water stream that pushes the clothes away during the washing process. In the case of a dual-power washing machine, since the inner tub and the pulsator can rotate simultaneously during the washing process, the water flow generated is stronger than when only the pulsator rotates. However, since only a simple washing water flow is included, the washing effect is limited and the improvement of the washing effect is not remarkable.

In this embodiment, it is possible to achieve a state in which the inner bath and the pulsator are relatively stationary during rotation during the cleaning process. As a result, since the water flow form when the inner tank and the pulsator rotate in the same direction and at the same speed is added, the variety of washing water flows is increased, and soft washing is realized. Therefore, the washing care effect on clothes is improved.

Specifically, the washing process of the washing machine includes a first operating state and/or a second operating state. In the first operating state, the inner tank and the pulsator are in relative motion when rotating, and in the second operating state, the inner tank and the pulsator are relatively stationary when rotating.

In the first operating state, the inner tank and the pulsator being in a state of relative motion include rotating the inner tank and the pulsator in opposite directions and rotating at the same or different speeds. Moreover, in the second operating state, the inner tank and the pulsator being in a relatively stationary state include that the inner tank and the pulsator rotate in the same direction and at the same speed. Specifically, the inner tank and the pulsator simultaneously rotate clockwise or counterclockwise at the same rotational speed.

During the same washing process, the washing machine may keep the inner tub and the pulsator relatively stationary during rotation, or keep them moving relative to each other. Alternatively, the relative stationary state may be performed only part of the time and the relative motion may be performed part of the time. By enabling switching between different states and realizing multiple types of water flow, the cleaning effect is further enhanced.

As an embodiment of this embodiment, this embodiment provides a control method for a washing machine. Specifically, it includes:

During the same washing process, the washing machine performs only the first operating state or only the second operating state.

In this embodiment, the inner bath and the pulsator can perform only the first operating state during the same cleaning process. In this case, the inner tank and the pulsator move relatively, rotating in the same direction at different speeds or in opposite directions. As a result, a relatively strong water stream can be formed, which is convenient for improving the cleaning effect.

In addition, the inner bath and the pulsator may perform only the second operating state during the same cleaning process. In this case, the inner tank and the pulsator maintain a relative stationary state all the time. That is, the inner bath and the pulsator rotate at the same speed and in the same direction during the cleaning process, creating a new type of water flow. This is convenient for soft washing of clothing made of light and soft materials.

In the cleaning process, when the inner bath and the pulsator rotate at the same speed and in the same direction, the following situations are involved.

Situation 1: During the cleaning process, the inner bath and the pulsator consistently rotate clockwise in the same direction and at the same speed.

Situation 2: During the cleaning process, the inner bath and the pulsator consistently rotate counterclockwise in the same direction and at the same speed.

Situation 3: During the cleaning process, the inner bath and the pulsator switch between rotating at the same speed and in the same direction clockwise and rotating at the same speed and in the same direction counterclockwise.

In any situation, the inner bath and pulsator maintain a relative stationary state throughout the same cleaning process, realizing a water flow form when the inner bath and pulsator rotate in the same direction and at the same speed. be done. As a result, even softer washing becomes possible, and the washing care effect for light and soft clothing is improved.

As an embodiment of this embodiment, this embodiment provides a control method for a washing machine. Specifically, it includes:

A washing process of the washing machine includes a first operating state and a second operating state, and is switchable between the first operating state and the second operating state.

In the first operating state, the inner tank and the pulsator are in relative motion when rotating, and in the second operating state, the inner tank and the pulsator are relatively stationary when rotating.

In this solution, it is possible to switch between two operating states during the cleaning process, and to generate different cleaning water flows in the two operating states. This increases the variety of washing water streams, thereby improving the washing efficiency and washing ratio of the clothes.

Specifically, the two operating states in the cleaning process include a state in which the inner bath and pulsator are relatively stationary and a state in which the inner bath and pulsator are in relative motion. When the inner tank and the pulsator are in a relatively stationary state during the rotation process, the direction of the formed water flow is the same and the flow velocity is stable. In this case, since the tensile force or stretching force applied to the clothes is reduced, the abrasion of the clothes can be reduced, and soft washing can be achieved. On the other hand, when the inner tank and the pulsator move relative to each other, the strength of the formed water flow increases. In this way, by switching between the above two types of states for washing and combining them with each other, not only can the washing effect be improved, but also the action of protecting the clothes and reducing wear and deformation of the clothes can be achieved. , can satisfy the needs of users.

In the cleaning process, the inner bath and the pulsator being relatively stationary in the second operating state include rotating the inner bath and the pulsator in the same direction and at the same speed. The inner bath and the pulsator may rotate clockwise or counterclockwise at the same rotational speed at the same time. In this case, both the inner tank and the pulsator rotate, but since their motions are completely synchronized, they are relatively stationary. At this time, since the water flow formed in the inner tank flows in the same direction at the same stable speed, the tensile force applied to the clothes in the inner tank due to the motion of the water flow is minimized. This type of soft wash is more suitable for easily deformable garments such as silk and wool.

On the other hand, in the first operating state, there are a plurality of types of methods in which the inner tank and the pulsator are in a state of relative motion, and depending on the method, it is possible to form a water flow of slightly different strength. In this embodiment, washing is performed by combining the water streams formed in the first operating state and the second operating state. The motion mode of the inner bath and the pulsator in the first operating state can include the following several schemes.

Method 1: The inner tub and the pulsator rotate in opposite directions, and the rotation speed of the inner tub and the pulsator are the same.

When the inner bath and the pulsator rotate in opposite directions and the rotation speeds of the inner bath and the pulsator are the same, two water streams rotating in opposite directions are formed. A powerful swirling water stream is formed where the two water streams collide with each other, and a large washing force is generated against the clothes, thus ensuring the cleaning effect and cleaning rate.

Method 2: The inner tub and the pulsator rotate in opposite directions, and the rotation speeds of the inner tub and the pulsator are different. Similar to the effect of method 1, the rotation of the inner tub and pulsator can form a strong swirling water flow, which generates a large washing force and pulling force on the clothes, so that the washing effect and cleaning rate are guaranteed.

As a preferred method, when the inner tank and the pulsator rotate in opposite directions, the rotation speeds are made different, and the difference between the rotation speeds is set to a constant value or a variable value. This makes it possible to preset a water flow of constant intensity. The intensity of the water stream is suitable for the majority of garments, which can ensure a high washing efficiency and avoid damaging the garments.

Solution 3: In the first operating state, the inner bath and the pulsator rotate in the same direction, but the rotation speeds of the inner bath and the pulsator are different. Even when the inner bath and the pulsator rotate in the same direction but at different speeds, it is possible to form a swirling water flow with great strength, thus ensuring cleaning efficiency.

Furthermore, the inner tank and the pulsator rotate in the same direction at different speeds, and the difference between the rotational speeds of the inner tank and the pulsator is a constant value or a variable value. By doing so, it is possible to preset a constant intensity of water flow, and it is also convenient for forming a stable washing program.

In the first operating state, the difference in rotational speed when the inner tank and pulsator rotate in opposite directions is equal to or less than the difference in rotational speed when the inner tank and pulsator rotate in the same direction at different speeds. By doing so, it becomes possible to form a relatively stable water flow with a relatively suitable strength, and the cleaning effect and cleaning rate are improved.

In addition, in this embodiment, when switching the execution of the first operating state and the second operating state in the same cleaning process, the following specific measures can be included as specific methods (however, but not limited to these).

Method 1: In the same washing process, the washing machine sequentially performs the first operating state/second operating state and the second operating state/first operating state.

In this scheme, the washing machine performs the first operating state once and the second operating state once. In this case, the first operating state may be performed first and then the second operating state may be performed, or the second operating state may be performed first and then the first operating state may be performed. The operating times of the first operating state and the second operating state can be set in advance as required. For example, after the user selects the operation of the washing program, the washing machine first executes the first operating state until time T1 is reached, and then controls the second operating state until time T2 is reached. The time T1 and the time T2 may be the same or different, and more specifically, may be set in advance as required or set by the user himself/herself.

Method 2: The washing machine is controlled to switch between the first operating state and the second operating state a plurality of times, so that the first operating state and the second operating state are alternately performed.

In this scheme, the washing machine performs the first operating state and the second operating state n times. The first operating state and the second operating state are executed alternately. The washing machine performs these switching periodically or irregularly. This further diversifies the water flow formed during the cleaning process. By combining the two types of operating conditions with each other, the objectives of high washing efficiency and high cleaning rate for clothes are achieved, and wear on clothes is also greatly reduced.

As a further method, the first operating state and the second operating state are alternately performed in the same cleaning process. Each time the first operating state is reached, the pulsator and inner bath rotate in opposite directions, or the pulsator and inner bath rotate in the same direction at different speeds. In the second operating state, the inner tank and the pulsator rotate clockwise or counterclockwise in the same direction and at the same speed.

When the washing machine alternately executes the first operating state and the second operating state a plurality of times, in the first operating state, the operating states of the inner tub and the pulsator may or may not be the same each time. good. For example, the inner bath and pulsator may rotate in opposite directions each time, or may move in the same direction at different speeds each time. Such driving is relatively regular, and the rotation direction of the clothes is also relatively regular, so that the tangling of the clothes can be reduced. Alternatively, the inner bath and the pulsator are first rotated in opposite directions, and then the inner bath and the pulsator are rotated in the same direction at different speeds. In this case, it becomes possible to form more diversified water streams, and the cleaning rate of the clothes is improved. On the other hand, in the second operating state, the inner tank and the pulsator rotate in the same direction at the same rotational speed. Each time the execution of the second operating state is switched, the inner tank and the pulsator may rotate at the same or different rotational speed as last time, may rotate clockwise, or may rotate counterclockwise. .

As a further method, the washing machine alternately performs the first operating state and the second operating state during the same washing process. Each time the first operating state is reached, the pulsator and the inner tank rotate in opposite directions. Moreover, the difference value between the rotation speeds of the pulsator and the inner tank is a constant value. In addition, the pulsator and the inner tank rotate clockwise in the same direction at the same speed each time the second operating state is entered. In this case, the operation of the inner tub and the pulsator is relatively regular, and the rotation direction of the clothes is also relatively regular, so that the tangling of the clothes can be reduced.

Further, in the second operating state, the pulsator and the inner tub rotate in the same direction, and the rotation speed is V1. The V1 is set to be equal to or greater than the smaller one of the rotational speeds of the inner tank and the pulsator during rotation in the first operating state. By doing so, the washing efficiency and washing ratio of the clothes can be improved, and the abrasion of the clothes can be reduced, and soft washing can be realized. Therefore, user's needs can be satisfied.

As an embodiment of this embodiment, this embodiment provides a control method for a washing machine. In the cleaning process in this embodiment, the first state, the second operating state, or both the first operating state and the second operating state are performed. In the first operating state, the inner tank and the pulsator are in relative motion when rotating, and in the second operating state, the inner tank and the pulsator are relatively stationary when rotating.

In this embodiment, the second operating state can be added to the washing process of the normal washing program in the conventional washing machine, and the soft washing mode can be independently set in the conventional washing machine. This adds a soft cleaning mode and allows the soft cleaning process to be performed independently. When the user selects a normal washing program or a soft washing mode that allows switching between washing processes, the washing machine switches between executing the first and second operating states during the washing process, or executes the second operating state alone. .

Specifically, in this embodiment, a soft washing program can be independently set based on a conventional washing machine program. This improves the user experience by increasing the washing programs available to the user and enriching the washing machine's programs. Specifically, it includes:

To facilitate user selection, conventional washing machines include a normal wash program, a fast wash program, and the like. Also, the washing machine further includes a soft wash program and a strong wash program. In the washing process of the soft washing program, the washing machine may execute only the second operating state, or may switch between executing the first operating state and the second operating state. In addition, the washing machine executes the first operating state during the washing process of the powerful washing program. In this case, during operation, the inner tub and the pulsator rotate in opposite directions to form a relatively strong water flow, thus improving the washing effect.

The soft washing program is a separate program based on the conventional washing machine, and is intended for clothes made of soft materials. When the user selects the soft washing program and operates, the washing machine can only execute the second operating state alone. In this case, the inner bath and the pulsator can rotate clockwise and/or counterclockwise at the same speed and in the same direction. Next, when the user selects the powerful cleaning program, the cleaning process is performed by switching to the first operating state. Further, in the soft cleaning program, the first operating state and the second operating state may be switched to operate while switching between a strong water flow and a weak water flow. This achieves the objectives of enhancing the flow of washing water, improving the washing effect, and avoiding deformation of the clothes.

Thus, the washing machine program includes not only a normal wash program, but also a strong wash program and a soft wash program. The user can independently select an appropriate washing program according to the material of the clothes, the degree of dirt, etc., and can switch between different washing programs/operating states. As a result, the washing program of the washing machine is enriched, the washing water flow is abundant, and not only the user experience is improved, but also the purpose of improving the washing and clothes care effect can be achieved.

1 to 14, this embodiment provides a washing machine having the speed reduction clutch device described in the above first to fifth embodiments. The washing machine has two washing states, the first operating state and the second operating state of the sixth embodiment. Moreover, the washing machine also has a dehydration state.

The washing machine includes a drive motor 32 . A drive motor 32 is connected to the input shaft 1 . During the washing process, when it is desired to proceed to the first operating state, the washing machine controls the drive member to move the connecting plate upwards into engagement with the positioning plate. The positioning plate thereby locks the braking axle via the connecting plate. In this case, when the drive motor rotates the input shaft, the input shaft 1 transmits power to the first shaft fixed gear train. The first shaft fixed gear train outputs power to the output shaft 22, which simultaneously transmits power to the second shaft fixed gear train. Then, the second shaft fixed gear train outputs power to the output bushing 21, so that the output shaft and the output bushing 21 rotate in opposite directions. On the other hand, when it is desired to proceed to the dehydration stage or to proceed to the second operating state, the washing machine controls the driving member to move the connecting plate downward to engage the torque transmission bush 33 of the input shaft. In this case, when the motor rotates the input shaft 1, the input shaft 1 and the brake wheelset 2 rotate synchronously. Then, the input shaft 1 and the braking wheel shaft 2 synchronously rotate the braking wheel 17 and the internal first and second fixed shaft gear trains, so that the output shaft 21 and the output bushing 21 are the same. Rotate in the same direction at the same speed.

It should be noted that the difference between the dehydration state and the second operating state is primarily the difference in rotational speed. The washing machine controls the motor to rotate at a high speed when desiring to proceed to the spin-drying state, but controls the motor to rotate at a low speed when desiring to proceed to the second operating state. In addition, another difference is that in the dehydration state, the washing machine controls the motor to rotate in one direction to achieve dehydration. On the other hand, in the second operating state, the washing machine controls the motor to repeatedly rotate forward and backward at intervals, thereby softly washing the clothes. A good cleaning effect is thereby achieved.
