Technical Field

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

[0002] In the prior art, the clutch device of the washing machine is installed below the inner barrel of the washing machine. The existing clutch device has a complex structure and occupies a large amount of space below the washing machine, causing the height of the washing machine to increase, making the washing machine larger and occupying more home space.

[0003] Chinese patent application number 201310355976.6 discloses a high-efficiency variable frequency motor deceleration clutch device and a washing machine. The deceleration clutch device comprises a clutch housing, an outer rotor motor consisting of a rotor and a stator, and an input shaft fixedly connected to the rotor and mounted on the housing. An input sleeve is disposed on the outer side of the input shaft and is rotatable about its axis. A clutch sleeve is mounted on the input sleeve and slides up and down. The clutch sleeve is connected to the traction motor via a control mechanism. When the clutch sleeve is in a first position, the input sleeve engages with the housing via the clutch sleeve. When the clutch sleeve is in a second position, the input sleeve engages with the rotor via the clutch sleeve. A control mechanism consisting of a connecting arm, a shift fork, and a clutch spring transmits the controllable traction force of the traction motor to the clutch sleeve, enabling the clutch sleeve to slide up and down. However, this solution requires the installation of a lower housing and control mechanism at the bottom of the inner tub. This washing machine clutch device is complex and occupies a significant amount of space below the inner tub.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a washing machine that uses the electromagnetic force generated by a driving module to drive the clutch assembly to move, drive the clutch assembly to move and connect / disconnect with the dehydration shaft, so as to realize the dehydration / washing function of the washing machine. The clutch assembly is arranged between the inner barrel and the outer barrel, saving the internal space at the bottom of the washing machine and reducing the volume of the washing machine.

[0006] In order to solve the above technical problems, the basic idea of the technical solution adopted by the present invention is: to provide a washing machine, including an inner tub, an outer tub, a washing shaft and a dehydration shaft sleeved on the washing shaft, one end of the dehydration shaft is connected to the inner tub, and further comprising:

[0007] A clutch assembly is slidably sleeved on the washing shaft between the inner tub and the outer tub;

[0008] The driving module is used to drive the clutch assembly to connect with / disconnect from the dehydration shaft through electromagnetic force, so that the dehydration shaft and the washing shaft rotate together or separately.

[0009] The present invention drives the bracket to move through electromagnetic force through the driving module, thereby driving the clutch assembly slidably mounted on the washing shaft to move, so that the washing shaft and the dehydration shaft can rotate integrally or non-integrally, thereby realizing the dehydration / washing function of the washing machine. The clutch assembly has a simple structure and is arranged between the inner and outer barrels, which occupies a small space, saves the internal space of the washing machine, and reduces the size of the washing machine. Under the condition that the size of the washing machine remains unchanged, the washing space of the washing machine can be increased, thereby realizing the washing capacity expansion of the washing machine.

[0010] Furthermore, there is a distance between the other end of the dehydration shaft and the bottom of the outer barrel, which at least constitutes a motion range for the clutch assembly to slide away from the dehydration shaft.

[0011] Furthermore, the clutch assembly includes a clutch ring, and the clutch ring has:

[0012] a first connecting member, configured to be integrally rotatably connected to the washing shaft;

[0013] The second connecting piece is used for engaging and connecting with the dehydration shaft.

[0014] Furthermore, the first connecting member is a spline provided on the inner peripheral wall of the clutch ring.

[0015] The second connecting member is a spline provided on the outer peripheral wall of the clutch ring, and the inner peripheral wall of the other end of the dehydration shaft is provided with a spline that matches and engages with the second connecting member;

[0016] Preferably, the clutch ring is a circular ring.

[0017] Furthermore, the spline on the outer peripheral wall of the clutch ring has a guiding slope at one end close to the dehydration shaft, and / or the spline on the inner peripheral wall of the dehydration shaft has a guiding slope at one end close to the clutch ring, for guiding the clutch ring into the dehydration shaft.

[0018] Furthermore, the clutch assembly also includes a bracket, which is slidably mounted on the washing shaft and located between the dehydration shaft and the outer barrel.

[0019] Furthermore, the center of the bracket in the longitudinal direction has a through hole for the washing shaft to pass through, and both ends of the bracket in the longitudinal direction extend from the through hole toward the peripheral direction;

[0020] Preferably, the bracket is a centrosymmetrical structure.

[0021] Furthermore, the bracket is provided with a force portion at positions close to both ends in the length direction, for cooperating with the driving module to generate a force to move the bracket in the axial direction;

[0022] Preferably, the force acting portion is symmetrically arranged with respect to the through hole.

[0023] Furthermore, a clutch spring is provided between the bracket and the bottom of the outer tub, the clutch spring is sleeved on the washing shaft, and two ends of the clutch spring are respectively in contact with the bracket and the outer tub.

[0024] Furthermore, the driving module is arranged on the outside of the bottom of the outer barrel, and the position of the outer barrel opposite to the driving module is made of non-magnetic material;

[0025] Preferably, the driving module is arranged opposite to two ends of the bracket.

[0026] In the present invention, when the washing machine clutch assembly is installed on the washing machine, the driving module does not need to be set at the bottom of the inner barrel of the washing machine, but can be set on the outside of the outer barrel of the washing machine. By installing a washing machine clutch device with a smaller structure, the space inside the washing machine is saved, the volume of the washing machine is reduced, the washing space of the inner barrel can be increased, and the washing capacity of the washing machine can be increased.

[0027] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0028] (1) The present invention drives the clutch assembly to move through electromagnetic force through the driving module, thereby driving the clutch assembly slidably mounted on the washing shaft to move, controlling the integral rotation of the washing shaft and the dehydration shaft or their separate rotation, thereby realizing the dehydration / washing function of the washing machine. The structure is simple and the operation and control are convenient. The clutch assembly has a simple structure and is arranged between the inner and outer barrels, which occupies a small space and saves the internal space of the washing machine, making the volume of the washing machine smaller. Under the condition that the volume of the washing machine remains unchanged, the washing space of the washing machine can be increased, thereby realizing the washing capacity expansion of the washing machine.

[0029] (2) In the present invention, when the washing machine clutch assembly is installed on the washing machine, the driving module does not need to be set at the bottom of the inner barrel of the washing machine, but can be set on the outside of the outer barrel of the washing machine. By installing a washing machine clutch device with a smaller structure, the space inside the washing machine is saved, the volume of the washing machine is reduced, the washing space of the inner barrel can be increased, and the washing capacity of the washing machine can be increased.

[0030] (3) The washing machine of the present invention does not have a deceleration device. By arranging a variable frequency motor on the outside of the outer barrel of the washing machine, the variable frequency motor controls and adjusts the rotation speed of the impeller and / or the inner barrel to wash. This simplifies the internal structure of the washing machine, saves space inside the washing machine, reduces the height of the washing machine, and increases the available space of the washing machine. This is conducive to increasing the capacity of the washing machine at the same volume. The washing machine of the present invention has a simple structure, is easy to install, and reduces costs.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0045] like Figures 1 to 7 As shown, the washing machine 8 of the present invention includes an inner barrel 81, an outer barrel 82, a washing shaft 1 and a dehydration shaft 2 sleeved on the washing shaft 1, one end of the dehydration shaft 2 is connected to the inner barrel 81, and further includes:

[0046] A clutch assembly is slidably mounted on the washing shaft 1 between the inner tub 81 and the outer tub 82;

[0047] The driving module 5 is used to drive the clutch assembly to connect with / disconnect from the dehydration shaft 2 through electromagnetic force, so that the dehydration shaft 2 and the washing shaft 1 rotate together / independently.

[0048] The present invention drives the clutch assembly to move through electromagnetic force through the driving module 5, driving the clutch assembly slidably mounted on the washing shaft 1 to move, so that the dehydration shaft 2 and the washing shaft 1 rotate integrally or non-integrally, thereby realizing the dehydration / washing function of the washing machine 8. The clutch assembly has a simple structure and is arranged between the inner barrel 81 and the outer barrel 82, occupying a small space, saving the internal space of the washing machine and reducing the volume of the washing machine. Under the condition that the volume of the washing machine remains unchanged, the washing space of the washing machine can be increased, thereby realizing the washing capacity increase of the washing machine.

[0049] The washing shaft 1 is arranged in the inner tub 81 and the outer tub 82. The washing machine 8 of the present invention is a drum washing machine or a pulsator washing machine. This embodiment is specifically described by taking a pulsator washing machine as an example.

[0050] Specifically, the drive module 5 is configured to drive the clutch assembly to engage or disengage with the spin shaft 2 through electromagnetic force, causing the spin shaft 2 and the washing shaft 1 to rotate together or independently. When the clutch assembly is engaged with the spin shaft 2, the spin shaft 2 and the washing shaft 1 rotate together; when the clutch assembly is disengaged from the spin shaft 2, the spin shaft 2 does not rotate with the washing shaft 1, but rotates independently.

[0051] There is a distance between the other end of the dehydration shaft 2 and the bottom of the outer barrel 82, which at least constitutes a range of motion for the clutch assembly to slide away from the dehydration shaft 2. The clutch assembly is sleeved on the washing shaft 1 and is located below the dehydration shaft 2 so as to slide up and down.

[0052] like Figures 2 to 7 As shown, the clutch assembly includes a clutch ring 3, and the clutch ring 3 has a first connecting member for being integrally rotatably connected to the washing shaft 1; and a second connecting member for being meshedly connected to the dehydration shaft 2.

[0053] In a preferred embodiment, the first connecting member is a spline provided on the inner circumferential wall of the clutch ring 3, the second connecting member is a spline provided on the outer circumferential wall of the clutch ring 3, and the inner circumferential wall of the other end of the dehydration shaft 2 is provided with a spline that matches and engages with the second connecting member. Preferably, the clutch ring 3 is a circular ring that rotates integrally with the washing shaft 1.

[0054] The spline on the outer wall of the clutch ring 3 has a guiding bevel (not shown in the figure) at one end close to the dehydration shaft 2, and / or the spline on the inner wall of the dehydration shaft 2 has a guiding bevel at one end close to the clutch ring 3, which is used to guide the clutch ring 3 into the dehydration shaft 2.

[0055] Another preferred solution is that the first connecting member is a spline provided on the inner wall of the clutch ring 3, the second connecting member is a clutch tooth (not shown in the figure) provided on the end face of the clutch ring 3 facing the dehydration shaft 2, and the end face of the other end of the dehydration shaft 2 is provided with end face teeth (not shown in the figure) that match and engage with the second connecting member, and the clutch ring 3 is a circular ring.

[0056] Furthermore, a flange 22 is provided at the upper end of the dehydration shaft 2, and the flange 22 is connected to the inner barrel 81. The flange 22 has a connecting hole 221 arranged along the axial direction.

[0057] Specifically, the dehydration shaft 2 is connected to the outer side of the bottom of the inner barrel 81, and the flange 22 of the dehydration shaft 2 is connected to the outer side of the bottom of the inner barrel 81. The outer side of the bottom of the inner barrel 81 is also provided with a hole, and the connecting hole 221 of the flange 22 and the hole of the inner barrel 81 are connected by bolts or screws.

[0058] The washing machine 8 also includes a pulsator 83 and a variable frequency motor 84. The variable frequency motor 84 is disposed on the outer tub 82. One end of the washing shaft 1 is connected to the pulsator 83, and the other end is in transmission connection with the variable frequency motor 84. The variable frequency motor 84 is disposed on the outside of the bottom of the outer tub 82. The washing shaft 1 is inserted into the outer tub 82 and in transmission connection with the variable frequency motor 84.

[0059] The washing machine 8 of the present invention is not provided with a deceleration device. By arranging a frequency conversion motor 84 outside the outer barrel 82 of the washing machine, the frequency conversion motor 84 controls and adjusts the rotation speed of the impeller 83 and / or the inner barrel 81 for washing, which simplifies the internal structure of the washing machine, saves space inside the washing machine, reduces the height of the washing machine, and is conducive to the capacity expansion of the washing machine. The washing machine of the present invention has a simple structure, is easy to install, and reduces costs.

[0060] The clutch assembly further comprises a bracket 4, which is slidably sleeved on the washing shaft 1 and is located between the clutch ring 3 and the outer barrel 82. The upper end of the bracket 4 can abut against the lower end surface of the clutch ring 3.

[0061] Preferably, the washing shaft 1 includes a first shaft segment 11, a second shaft segment 12 and a third shaft segment 13 connected in sequence from top to bottom, the diameter of the second shaft segment 12 is larger than the diameters of the first shaft segment 11 and the third shaft segment 13, and the outer peripheral wall of the upper end of the second shaft segment 12 is provided with a spline that can engage with the clutch ring 3. When the bracket 4 is pressed down, it is sleeved on the smooth outer peripheral wall of the lower end of the second shaft segment 12.

[0062] The dehydration shaft 2 is sleeved on the washing shaft 1 and includes a coaxially arranged stepped hole, which includes a first hole segment 23, a second hole segment 24, and a third hole segment 25 connected in sequence at the upper and lower ends. The aperture of the second hole segment 24 is smaller than that of the first hole segment 23 and the third hole segment 25. The first hole segment 23, the second hole segment 24, and the third hole segment 25 are straight through holes.

[0063] The inner wall of the dehydration shaft 2 is provided with ribs 21 along the circumferential direction. The dehydration shaft 2 is located above the connection between the first shaft section 11 and the second shaft section 12 through the ribs 21, which can prevent the washing shaft 1 from passing through the dehydration shaft 2.

[0064] One end of the dehydration shaft 2, having the first hole section 23, is connected to the inner barrel 81. A rib 21 is provided on the inner wall of the lower end of the first hole section 23. The third hole section 25 is provided with a spline that matches the clutch ring 3. Under the action of an external force, the clutch ring 3 enters the third hole section 25 at the lower end of the dehydration shaft 2 and connects with the spline in the third hole section 25.

[0065] The washing machine 8 also includes a pulsator 83 and a variable frequency motor 84. Specifically, the first shaft section 11 is connected to the pulsator 83, and the third shaft section 13 is transmission-connected to the variable frequency motor 84. The washing shaft 1 drives the pulsator 83 to rotate, and the speed of the washing shaft 1 is controlled by the variable frequency motor 84. The dehydration shaft 2 can rotate integrally with the washing shaft 1.

[0066] A sealing structure 7 is provided at the connection between the upper end of the dehydration shaft 2 and the washing shaft 1 , which can cooperate with the inner barrel 81 to prevent water in the barrel from flowing out of the inner barrel 81 .

[0067] The sealing structure 7 is sleeved on the washing shaft 1 and installed above the rib 21. Preferably, the rib 21 is a circular rib.

[0068] The center of the bracket 4 in the longitudinal direction has a through hole 42 for the washing shaft 1 to pass through, and both ends of the bracket 4 in the longitudinal direction extend from the through hole 42 toward the periphery. The aperture of the through hole 42 is smaller than the outer diameter of the clutch ring 3.

[0069] Preferably, the bracket 4 is a sheet metal member having a length. The bracket 4 is a support plate or a support rod. The bracket 4 is a rectangular plate, a long rod, or a special-shaped plate. Preferably, the bracket 4 has a centrally symmetrical structure. The length of the bracket 4 matches the diameter of the outer barrel 82.

[0070] The bracket 4 is provided with a force portion 41 at positions near both ends in the length direction, which is used to cooperate with the driving module 5 to generate a force to move the bracket 4 along the axial direction; preferably, the force portion 41 is symmetrically arranged with respect to the through hole 42.

[0071] The force acting portion 41 is made of metal material and is subjected to the electromagnetic force generated by the driving module 5 when it is powered on, so as to move the bracket 4 downward. The force acting portion 41 is a metal frustum or a metal cylinder protruding from the upper side and / or the lower side of the bracket 4.

[0072] The driving module 5 of the present invention drives the bracket 4 to move through electromagnetic force, driving the clutch ring 3 mounted on the washing shaft 1 to slide up and down, enter and move out of the interior of the dehydration shaft 2, and the washing shaft 1 engages or disengages with the inner ring of the dehydration shaft 2 through the clutch ring 3. When engaged, the dehydration shaft 2 rotates integrally with the washing shaft 1; when disengaged, when the washing shaft 1 rotates, the dehydration shaft 2 and the washing shaft 1 do not rotate integrally, thereby realizing the clutch function of the washing machine. It has a simple structure, small size, and occupies little space.

[0073] A clutch spring 6 is provided between the bracket 4 and the bottom of the outer barrel 82 . The clutch spring 6 is sleeved on the washing shaft 1 . Both ends of the clutch spring 6 are in contact with the bracket 4 and the outer barrel 82 , respectively.

[0074] When the washing machine 8 is dehydrating, the driving module 5 is powered off, the bracket 4 is no longer subjected to downward force, and the clutch spring 6 is no longer squeezed. The clutch spring 6 recovers its deformation, and the clutch spring 6 presses the bracket 4 upward, so that the clutch ring 3 engages with the dehydration shaft 2.

[0075] The driving module 5 is arranged on the outside of the bottom of the outer barrel 82, and the position of the bottom of the outer barrel 82 opposite to the driving module 5 is made of non-magnetic material. Preferably, the driving module 5 includes two electromagnet modules, which are symmetrically arranged on both sides of the center of the bottom of the outer barrel 82.

[0076] The driving module 5 is disposed opposite to both ends of the bracket 4 . The driving module 5 is disposed at positions corresponding to those of the force acting portion 41 of the bracket 4 .

[0077] The distance between the driving module 5 and the washing axis 1 is equal to the distance between the force acting portion 41 and the washing axis 1 .

[0078] In the washing machine 8 described in the present invention, the driving module 5 does not need to be set at the bottom of the inner barrel 81 of the washing machine, nor does it need to be connected to the clutch assembly. It is simple to operate and can be set on the outside of the outer barrel 82 of the washing machine, saving the internal space between the inner and outer barrels of the washing machine, making the volume of the washing machine smaller, and can increase the washing space of the inner barrel, thereby realizing the washing capacity expansion of the washing machine.

[0079] The drive module 5 of the present invention comprises two electromagnet modules, symmetrically positioned on either side of the bottom center of the outer barrel 82. These modules generate electromagnetic force when powered on and dissipate it when powered off. The two electromagnet modules are mounted on the outer barrel 82 at positions opposite the force-applying portions 41 at either end of the bracket 4.

[0080] The driving module 5 has two working states:

[0081] In the first working state, the driving module 5 generates electromagnetic force when powered on, driving the bracket 4 to move downward, pressing the clutch spring 6 downward, so that the dehydration shaft 2 is disengaged from the clutch ring 3;

[0082] The second working state is that the electromagnetic force disappears when the driving module 5 is powered off, and the clutch ring 3 is bounced up by the clutch spring 6 and engages with the dehydration shaft 2 .

[0083] Specifically, when the driving module 5 is energized, an electromagnetic force is generated. When the bracket 4 is within a certain range of distance from the two electromagnet modules, the two ends of the bracket 4 are subjected to the downward electromagnetic force of the driving module 5, squeezing the clutch spring 6. The bracket 4 moves downward, and the clutch ring 3 loses its supporting force and disengages downward from the dehydration shaft 2, so that the dehydration shaft 2 cannot rotate as a whole with the washing shaft 1. The frequency conversion motor 84 drives the impeller 83 to rotate through the washing shaft 1, thereby washing the clothes.

[0084] When the drive module 5 is powered off, the electromagnetic force disappears. When the force exerted by the drive module 5 on the bracket 4 is removed, the extrusion on the clutch spring 6 is released. The clutch spring 6 recovers its deformation upward, pushing the bracket 4 upward, driving the clutch ring 3 upward and entering the inner ring of the dehydration shaft 2. The clutch ring 3 engages with the dehydration shaft 2, causing the dehydration shaft 2 to rotate integrally with the washing shaft 1. When the variable frequency motor 84 rotates, it drives the inner tub 81 to rotate, dehydrating the clothes.

[0085] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments of equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above-mentioned embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above-mentioned embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
