    [001] The present patent application refers to the technical field of washing machine and, particularly, to a double drive transmission method, mechanism, washing machine and washing method.
    [002] Washing machine is a machine that can wash clothes through chemical decomposition and mechanical impact function. It mainly uses the drive device to turn the rotor so as to stir up the water and the clothes, thus performing the washing function of the clothes. The conventional drive device as a power source is motor, and the motor output shaft transfers the torque from the motor rotation to the reducing device. It connects the output shaft of the reducing device to the rotor, thus causing the rotor to rotate.
    [003] As the normal motor speed is quite high, to obtain adequate output speed, the motor speed needs to be decelerated in the effective application. Now, the normal method is to reduce the motor speed by the level of a gearbox pulley. In the reducer, it is possible to configure one level or more levels of the gear reducer mechanism to obtain the reduction in a certain ratio. This structure is not only complicated but also takes up a lot of space. To solve the above technical problem, an actual solution is applied to remove the pulley and connect the motor and gear directly, but due to this, the motor and gear itself still remain in individual position, so they take up mounting space separated. As a result, the structure is not compact enough and the volume is too large.
    [004] To solve the above-mentioned technical problem, an external rotor motor assembly is provided according to China's invention No. CN102142734A disclosed, which includes the motor body, drive shaft and transmission device. The drive shaft is fixed to the drive device, the motor itself directly drives the drive shaft, the motor body has an inside diameter space, and the drive device is mounted within the inside diameter space. Although the structure has already reduced the space occupied to some extent, its principle is to utilize the inner circumference space of the stator of the external rotor motor for mounting the transmission device in the inner diameter space of the stator by mounting pieces. Therefore, it cannot be applied to the inner rotor motor without the inner space, so it has certain limitations. Meanwhile, its own engine directly drives the drive shaft, and then to reduce the drive shaft speed by the transmission device mounted within the engine's inner diameter space, so it only reduces the space occupied to some extent, but the structure is not compact enough. Additionally, when the transmission device needs to get high gear ratio and needs to increase the volume, it certainly needs to make the outer rotor motor inner diameter increase the volume to accomplish this application. So it obviously doesn't solve the real technical problem.
    [005] In addition, all current washing machines carry out the washing at a certain fixed speed, regardless of whether the washing load is large or small, and the washing shaft still rotates at the same speed to wash, this type of washing method can not only easily damage clothes, but also damage the washing machine motor if it is overloaded.

    [0067] An object of the present patent application is to provide a type of drive device of the washing machine and the washing machine with the drive device of the washing machine, which had small axial dimension, compact structure and little space busy.
    [0068] Figure 17 is a top view showing the drive device of the washing machine of the present patent application, and Figures 1 and 7 are the cross-sectional view showing the two configurations of the drive device of the washing machine as shown in Figure 17. As shown in Figures 1 and 7, the washing machine of the present patent application consisting of: a rotating body without an axis that provides rotational energy; mounting the speed reducing device on the rotating body, and obtaining the rotating energy from the central position of the rotating body, and producing the force at the speed of rotation equal to or less than the speed of the rotating body; the washing shaft and the slewing tube are connected to the speed reduction device, which transfers the energy of the rotation speed equal to or less than the rotation speed of the rotating body under the speed reduction device energy supplied separately to the washing running part and the washing machine rotating running part; where, the swivel tube is jacketed on the outside of the washing shaft and also connected by rotation to the washing shaft.
    [0069] The rotating body that provides rotational energy in the present patent application is a pulley or a motor rotor, both of which have a drive structure (such as a motor rotor structure or a pulley structure) and are installed on the inside the empty cavity of the drive frame. The motor rotor can be the inner motor rotor or the outer motor rotor, to be easily understood, the configuration in the present patent application only explains the inner motor rotor. It should be known that persons qualified in this technical field can also use the technical solution described in this patent application, for example, to replace the internal motor rotor mentioned in this configuration by the pulley or external motor rotor, in addition, in the case of replacement of the part, thus modifying the structure of the present patent application in a corresponding way, will not result in innovation of this patent.
    [0070] The present patent application can also use different types of motor, such as a motor, Servomotor, PSC motor, BLDC motor and so on.
    [0071] A dual drive transmission device provided in this patent application consists of the speed reduction mechanism, which includes an input piece, rotating output piece and oscillating output piece, in which:
    [0072] The input parts are fixedly connected to a motorized part that provides a rotation drive energy ;i.e., the rotating body above without shaft<;
    [0073] The swivel output piece connects ixamete to a tuo and iro to muia and avar
    [0074] The oscillating output piece connects the shaft to the shaft and avaem a muia and avar
    [0075] The oscillating output piece is fixedly connected to the input piece, so that the oscillating output piece rotates around the shaft by the motor part.
    [0076] The swivel output piece is meshed with the swivel output piece, allowing the swivel output piece and the swivel output piece to interact with each other and rotate separately on their own axes, resulting in drive of the wash shaft and the swivel tube to perform rotation individually.
    [0077] In one configuration, the motorized part in the present patent application is the drive frame or the drive frame with empty cavity. The input part is an eccentric sleeve that is mounted inside the empty cavity, is connected to the pulley or motor rotor and rotates around the wash shaft. The oscillating output piece consisting of: a spur gear which is housed on the outside of the eccentric sleeve and rotationally connected to it, rotating around the axis of the eccentric sleeve with the rotation of the eccentric sleeve itself; a connecting device that connects the spur gear to the wash shaft or swing tube. The rotating output piece is a sprocket which is connected to the slewing tube or wash shaft, and into which the spur gear is placed, so that during the revolution, the spur gear rotates on its own axis as a result of its meshing with the inner teeth of the sprocket, causing the sprocket to rotate on its own.
    [0078] On the other hand, the dual drive transmission output method for a washing machine, comprising steps in the following sequences:
    [0079] Fixedly connecting an input part of a speed reduction mechanism to a motorized part to provide rotational drive eneria;
    [0080] Fixingly connecting a rotating output piece of the speed reduction mechanism to a rotating tube of the washing machine;
    [0081] Connecting an oscillating output part of the speed reduction mechanism to a washing shaft of the washing machine;
    [0082] By connecting the oscillating output part to the input part, the oscillating output part rotates around an axis of the motorized part; and
    [0083] By means of the mesh connection between the swiveling output piece and the oscillating output piece, it allows the swiveling output piece and the oscillating output piece to interact with each other, and rotate separately on their own axes, in order to activate the washing shaft and the rotating tube to perform the rotation individually.
    [0084] During the rotation of the washing shaft, the washing shaft transfers the reactive force from a washing load to the yacht outlet part; and the yacht's axle transfers the reactive force from the washing load to the rotary outlet part, then the The interaction force between the oscillating output piece and the rotating output piece is changed, therefore, the individual rotation speed of the oscillating output piece and the rotating output piece varies depending on the washing load. That is, when the wash load increases, the autorotation speed of the rotating output piece also increases accordingly, which also reduces the autorotation speed of the swinging output piece, moreover, when the wash load decreases, the The rotating output piece's autorotation speed also reduces accordingly, which also increases the rotating output piece's autorotation speed.
    [0085] Especially, the transmission means between the input piece of the speed reduction mechanism, the oscillating output pieces and the rotating output pieces is provided in plane for reduction operation.
    [0086] As shown in Figure 1, 2, 7 and 8, the motorized part of the present patent application is the drive structure or equipped with the drive structure and the drive structure with empty cavity 3. The input part of the speed reduction mechanism is the eccentric sleeve 4 which is mounted inside the drive frame 3, connected to the drive frame 31 and rotating around the wash shaft 5. The oscillating output piece consisting of: spur gear 6 housed outside of eccentric sleeve 4 and connected by rotation to eccentric sleeve, which rotates around the axis of eccentric sleeve 4 with rotation of eccentric sleeve &; the connecting device that connects the sprocket 6 to the washing shaft 5. The swivel output piece is the sprocket 7 which connects the slewing tube 20, and the spur gear 6 is installed inside the sprocket, allowing the gear to straight 6 is engaged with the inner teeth of ring gear 7 during the revolution interval, which causes the drive gear to rotate by itself.
    [0087] As shown in Figure 19, the motorized part of the present patent application is the drive structure, the input device mounting on the drive structure 3, and the input part consisting of the input gear shaft 51 which is mounted in the offset position of the drive frame shaft and the input gear which connects to the input gear shafts including the first input gear 52 and the second input gear 54. The oscillating output piece is the output gear which is meshed with the second input gear (& of the input gear the rotating output piece is the intermediate gear 53 located outside the drive frame and meshed with the first input gear 52 of the input gear.
    [0088] In the present patent application, the motor's inner rotor provides the rotational energy when rotating around its own axis, the speed reduction mechanism installed inside the inner rotor can change the output speed of the inner rotor, due to When the speed reduction mechanism is connected to the inner rotor, the speed reduction mechanism can obtain rotational energy while rotating the inner rotor around its own axis. Because of this, the eccentric sleeve of the speed reduction mechanism connected to the inner rotor rotates around the inner rotor axis eccentrically, allowing other parts of the speed reduction mechanism to rotate around the inner rotor axis eccentrically and also that the energy coming from the eccentric rotation is transferred to the output force where the rotation speed is equal to or less than the internal rotor speed. Thus, the speed reduction mechanism connects to the washing shaft, and one end of the washing shaft connects to the washing machine rotor (or agitator, this will not be repeated hereafter and is not shown in the Figure), and the tube swivel tube 20 is housed on the outside of the washing shaft and is connected by rotation to the washing shaft, and the slewing tube connects to the washing machine basket (this is not shown in the Figure), thus exercising the power function. output of the speed reduction mechanism, the washing shaft and the rotating tube supply the energy from the rotation speed which is equal to or less than the speed of the inner rotor individually to the corresponding running parts, as a result, the assembly of the washing machine with the drive device of the washing machine in the present patent application can realize the function of washing clothes.
    [0089] In the present patent application, as shown in Figure 17, 1 and 7, the stator 2 is installed inside the housing assembly 1 and the internal rotor 3 installed inside the stator 2, which provides rotation energy. The inner rotor in the present patent application comprises the drive structure 31 and the empty cavity 32 installed within the drive structure, so that the rotation speed of the inner rotor is the speed of the drive structure and also the axis of rotation. The drive structure is symmetrical axis. In this sense, the speed reduction mechanism is mounted inside the empty cavity of the drive structure, and the speed reduction mechanism comprising the transmission device, and the transmission device containing: the spur gear 6 which is housed outside the eccentric sleeve and connected by rotation to the eccentric sleeve, which rotates around the axis of the drive frame with the rotation of the eccentric sleeve; the sprocket 7 which is connected to the slewing tube 20, and the sprocket is positioned within the sprocket, allowing the sprocket to be meshed with the inner teeth of the sprocket to rotate alone during the period of revolution, and thus the sprocket rotates as a result during the process that is engaged with the spur gear, also transferring the eneria of rotation to the spur of iro; where the spur gear connects to the washing shaft 5 via the connecting device, and then transfers the rotational energy to the washing shaft. Otherwise, the speed reduction mechanism in the present patent application also includes the clutch coil assembly which controls the output speed of the reduction device, which is installed within the housing assembly and is axially jacketed by sliding over the outer wall of the sprocket, and its teeth engaged or disengaged with the teeth at one end of the sliding drive device in the axial direction, thus it drives the rotation speed output by the speed reduction mechanism to become equal or less than the rotational speed of the drive frame.
    [0090] The transmission device in the present patent application, the spur gear is connected to the washing shaft by a connecting device and there are different types of connecting device structure, in the following, the present patent application is described in detail in set with the configuration hereafter.
    [0091] The first configuration of the present patent application is:
    [0092] As shown in Figures 1 and 2, they are a schematic view showing the structure of the washing machine device in the present patent application where the connecting device is a slider.
    [0093] As shown in Figure 1, the motor in this configuration is an internal motor rotor. In which, the housing assembly consists of: tube housing 11 with opening holes at both ends, the motor end cap which is connected to the bottom of the housing 11, the mounting disk 14 at the top of the housing which is connected to the motor end cap 12 by motor screws 13, and housing 11, motor end cap 12 and mounting disc 14 integrated as an internal space for installing stator 2, inner rotor and other parts.
    [0094] The internal rotor in the configuration of the present patent application consisting of the drive structure 31 and the empty cavity 32 installed inside the drive structure, whose upper end has teeth 33. In detail, as shown in Figures 1 and 12, the drive frame in this configuration including the tube rotor 34 and the rotor insert 35 into the rotor, and the rotor insert including: cylinder 351 with opening holes at both ends, teeth 33 at the top and projecting upwards; the base plate %(# positioned at the bottom of the cylinder and an opening hole in the center of the base. The rotor insert cylinder and the base plate combine the empty cavity 32 for installation of the speed reduction mechanism and the wash shaft passes through the center of the base hole, so when the drive frame rotates, it has the same rotation axis as the wash shaft, ie the rotation axis of the drive frame coincides with the axial rotation of the wash shaft.
    [0095] In this configuration, as shown in Figure 2, the speed reduction mechanism installed within the empty cavity of the inner rotor and the speed reduction mechanism including transmission device and clutch coil assembly, and transmission device including sleeve cam 4, sprocket 6, sprocket 7 and connecting device 8.
    [0096] The eccentric sleeve of the transmission device is fixedly connected with the drive frame 31 and the eccentric sleeve rotates around the axis of the drive frame. As shown in Figure 6, the eccentric sleeve consists of the first tube that rotates around the same axis of rotation as the drive frame and the first tube that rotates offset from the axis of the drive frame. Wherein, the second tube and the first tube can be fixedly connected by separate pieces or can be fixedly connected by one-piece combination. In order to be convenient for machining or assembly, preferably, as shown in Figure 2, the second tube is only the second tube 43, and the first tube consisting of the eccentric connecting piece 41 which is connected to the top of the second tube, and the first tube 42 which is connected to the top of the eccentric connecting piece, whereby the eccentric connecting piece 41 has the outer edge projected by the outward extension of the first tube 42 and no eccentric sleeve hole passing through the second tube 43, and the eccentric sleeve remains extended upwards and passes through the eccentric connection piece and through the first tube.
    [0097] In eccentric sleeve machining, the first tube, the eccentric connecting piece and the second tube can form a single piece or connect as a single piece by welding and, in the case of machining, between the centerline of the first tube and the centerline of the second tube may be a certain eccentric distance, the eccentric distance being equal to the difference between the radius of the spur gear and the radius of the sprocket.
    [0098] In this configuration, the fixed connection between the eccentric sleeve 4 and the drive frame 3 is the rigid connection to transfer the rotation torque. In machining, the eccentric sleeve and the drive frame can be fixedly connected to form a single piece, or they can be connected by combining separate pieces, such as screw connection, welding, etc. The preferred method in detail is of the type: tube rotor 34 uses metal material, eccentric sleeve 4 uses metal material, tube 34 rotor and eccentric sleeve 4 are placed on plastic injection tools or casting tools , they are molded as rotor and eccentric sleeve by plastic injection or casting and then are mounted on the % insert (8 (four grooves shown in Figure 2) or guide should be mounted on the outside of the extended edges of the eccentric connection piece 41 on the eccentric sleeve, thus, by increasing the bonding force during plastic injection or casting of eccentric sleeve 4 and drive structure 31, it can meet the requirement of being rigidly connected between eccentric sleeve 4 and eccentric sleeve activation 31.
    [0099] During the rotation of the drive frame, the eccentric sleeve that is fixedly connected to the hole of the rotor insertion base by the second tube that rotates around the same axis and at the same speed as the drive frame. In this way, it drives the spur gear which is connected by rotation to the first tube 42 of the eccentric sleeve to rotate accordingly.
    [00100] As shown in Figure 5, the spur gear 6 in the configuration of the present patent application comprising the steel ring 63 and the outer teeth 60 that together form a single piece by plastic injection, and a pair of grooves 62 being extreme direction relatives are installed on the upper end surface of the spur gear. In this configuration, the steel ring is connected by rotation to the first tube of the eccentric sleeve and, in the detailed method: the outer wall of the first tube 42 and the inner ring of the bushing 100 are connected as an interference fit, but the upper end of the extended outer edge of the eccentric connection piece is contact connected to the lower end of the extended outer edge of buc8a 100; or the outer wall the outer wall of the first tube 42 and the inner ring of the bushing 100 can be connected as a clearance connection, but the upper end of the outer extended edge of the bushing 100 and the lower end of the outer extended edge of the bushing 100 are connected by contact and the outer ring of bushing 100 and the inner wall of the spur gear are connected as an interference fit.
    [00101] Of course, in order to realize the relative rotation connection between the eccentric sleeve 4 and the spur gear, the method applied in detail can be as follows: to improve the structure of the eccentric sleeve 4, how to use metallurgical material, which allows the eccentric sleeve 4 to have the function of bushing 100 to avoid using bushing 100 separately, so as to connect by rotation the steel ring to the eccentric sleeve, which has the bushing function.
    [00102] Preferably, several material reduction chutes within the first tube 42 to reduce the cost of production and the material having lubrication function can be added to the material reduction chutes, such as lubricating oil, cottonseed oil, in addition to increasing the life of the eccentric sleeve.
    [00103] When the eccentric sleeve rotates, the spur gear rotation is connected by rotation to the first tube above the eccentric sleeve which rotates in the same direction of rotation with the eccentric sleeve. There is a certain eccentric distance between the centerline of the first tube of the eccentric sleeve and the centerline of the second tube, and the axis of rotation of the first tube coincides with the axis of the drive frame, so when the spur gear is rotating , it will actually be rotating eccentrically around the axis of the drive frame.
    [00104] During spur gear rotation, because the outer teeth are meshed with the sprocket, it can transfer its rotational force to the sprocket. The sprocket in this configuration is a plastic or metallic connecting piece, the metal or plastic connecting piece consisting of the upper connecting piece 71 and the lower connecting piece 72 located underneath it and connecting the upper connecting piece . As shown in Figure 14, the upper connecting piece is housing and the outer groove 711 is arranged in the outer wall along the axial direction and several guides 712 arranged in its inner wall along the axial direction; the lower connecting piece *# is tubular structure, its upper portion is fixedly connected to the upper connecting piece and the outer teeth 721 installed on its inner wall, and many gussets 723 arranged in the connecting area between the upper connecting piece and the bottom connection piece, and an adjacent brace 723 mounted with guide 722 containing spring installation holes 200.
    [00105] As shown in Figure 13, the various guides in the upper connection piece correspond with the various tube grooves 201 arranged in the outer wall of the swivel tube, thus allowing the sprocket to be fixedly connected to the swivel tube as a single piece. In addition, it is possible to use metal connection piece to obtain a rigid connection to the swivel tube using laser welding or other procedures. In the present embodiment, the inner teeth 721 on the inner wall of the lower connecting piece 72 can be made of plastic or metal.
    [00106] When the spur gear is in rotation (that is, rotating eccentrically around the axis of the drive frame), its outer teeth are meshed with the inner teeth of the sprocket, thus, by the interaction force of the gearing, it drives the sprocket to rotate on its own axis and the current rotation direction is opposite to the rotation direction, also due to the differences in the number of teeth between its external teeth and the internal teeth of the sprocket, and the sprocket may have speed differences during its autorotation and revolution, that is, the autorotation speed is less than the revolution speed, thus the rotation output speed is less than the rotational speed of the drive frame. Likewise, due to the interaction force exerted by the sprocket and the sprocket, the sprocket may rotate when the sprocket is in autorotation, but the sprocket rotation direction is opposite the sprocket rotation direction, being the rotational direction of the sprocket is equal to the rotational direction of the drive frame, and the rotational speed of the sprocket is less than the rotational speed of the drive frame.
    [00107] In conclusion, the spur gear under the influence of the rotation of the eccentric sleeve and because it is meshed with the ring gear, it can rotate and make autorotation at the same time, and the direction of autorotation is opposite to the direction of revolution, with the speed of rotation during autorotation it is less than the speed of rotation of the drive frame; the sprocket under the corresponding action, rotates at a speed lower than the rotational speed of the drive frame in the direction of the spur gear autorotation.
    [00108] When the spur gear rotates by itself at low speed, it transfers energy to the wash shaft through the sliding frame. The slide structure in this configuration includes: the cross slide 85 which passes through the wash shaft and its lower end surface is slide connected with the upper end surface of the spur gear; the positioning derailleur 86 which is slidingly connected with the upper end surface of the cross-slider and its center is fixedly connected to the wash shaft. As shown in Figure 4, the cross slider including; the disc body 851 passing through the wash shaft; a lower guide pair 852 respectively installed on the lower end surface of the disc body and relative to the radial direction; an upper guide pair 853 installed on the upper end surface of the body relative to the radial direction and its extended line and the extended line of a lower guide pair are crossed in space. As shown in Figure 3, the positioning slider consists of: slider body 861 in tubular form, its center fixedly connected to the wash shaft; a pair of "optical placode" 862 in position disposed on both sides of the sliding body and along the radial direction, a pair of grooves 863 corresponding to a pair of upper ones. Preferably, a pair of gear grooves installed on the upper end surface of the spur gear and relative to the radial direction, which corresponds to the position of a lower guide pair.
    [00109] Specifically, as shown in Figure 5, in this configuration, a lower guide pair on the cross slider 85 respectively installed in a gear groove pair 62 on the gear upper end surface, and a lower guide pair respectively sliding within a pair of gear grooves in relative position; a pair of cross-sliding upper guide 85 respectively disposed within a pair of grooves 863 under the surface of the positioning slider, and a pair of upper guide may respectively slide within a pair of grooves; the center of the positioning slider body is fixedly connected to the washing shaft, and thus it drives the centerline of the positioning slider to coincide with the centerline of the washing shaft.
    [00110] During spur gear self-rotation, a pair of gear slots 62 above it rotates at the same speed and in the same direction as the spur gear, thereby driving a pair of lower guide 852 installed in a pair of gear slot to rotate together, that is, the entire cross slider rotates together with the spur gear, under centrifugal force, a lower guide pair on the cross slider and an upper guide pair respectively slide in a pair of gear slots and a pair of groove 863 along the radial direction and during the sliding process, that is, the sliding process occurs from the direction of the spur gear shaft 40 in the direction of the wash shaft shaft 50. Due to an upper guide pair on the cross slider in sliding arrangement within a pair of slots 863 of the positioning slider, rotation of the guide results in rotation of the slot, i.e., the positioning slider also slides on account of this. The center of the positioning slider is fixedly connected to the washing shaft, so when the positioning slider rotates, it makes the washing shaft rotate with the spur gear in the same direction and at the same speed.
    [00111] As shown in Figure 2 and 18, when the spur gear rotates eccentrically around the shaft of the wash shaft, through the slider structure, it can transfer the force resulting from the rotation of the spur gear around shaft 40 of the spur gear to the rotation force of the wash shaft around the shaft 50 (ie the drive frame shaft) of the shaft, that is, transferring the output of the spur gear which rotates eccentrically around the shaft of the wash shaft for the wash shaft output on the same shaft.
    [00112] As the washing machine has different washing conditions, it needs to adjust the output speed of the speed reduction mechanism according to different washing conditions. In washing condition, the speed reduction mechanism output speed should be at low speed, and in rotation state, the speed reduction mechanism output speed should be at high speed. Therefore, in the present patent application, the speed reduction mechanism consists of a clutch coil device, which is installed in the empty cavity of the housing assembly and jacketed by sliding on the outside of the outer wall of the sprocket in the axial direction, engaging and disengaging with teeth 33 on the extreme surface of the drive frame, it makes the speed reduction mechanism work at high or low speed.
    [00113] Specifically, the clutch coil device in this configuration is a magnetic clutch coil device, including electromagnetic coil mechanism and slider 91, the electromagnetic coil device being disposed on the outside of the slider.
    [00114] The electromagnetic coil mechanism comprises the electromagnetic coil 92, coil structure 93 and coil support. The coil support is fixedly mounted to the mounting plate 14 of the housing assembly, and the coil frame is mounted inside the coil support, but the electromagnetic coil is installed over the coil frame.
    [00115] Slide 91 consists of the top connecting piece and the bottom connecting piece. The top connecting piece and the bottom connecting piece can be fixedly connected by as separate pieces or they can be fixedly connected as a single piece. To be convenient for machining or assembly, preferably, as shown in Figure 16, the top connecting piece is the tube frame, and the inner spline 911 is disposed on the inner wall, and the magnetic iron ring 912 is molded as one piece by plastic injection into the outer wall, and the inner spline 911 and the outer spline 711 in the outer spline on the outside of the sprocket are slidingly coupled. The magnetic iron ring is coupled to the electromagnetic coil so that it is away from the coil under the magnetic force of the electromagnetic coil; many guide teeth in certain spaces located on the extreme surface of the bottom of the lower connecting piece and the teeth of the adjacent guide teeth form the tooth groove 913, and the tooth groove 913 engage with teeth 33 on an end surface of the frame of drive, preferably several material discharge chutes installed around the lower connecting piece serve to reduce production costs.
    [00116] When the electromagnetic coil is energized, under the repelling force of the electromagnetic coil, it activates the magnetic iron ring, which moves downwards to move away from the electromagnetic coil, and the magnetic iron ring is fixedly connected to the upper part of the slider, thus, under the magnetic iron ring and it drives the entire slider 91 to slide down the outer wall of the slider and reach the second locating position, in which the teeth groove of the lower connecting piece of the slider is engaged with the teeth of the drive structure, therefore, the sprocket obtains the same rotational speed as the drive structure allowing the transmission disosion to be traced; On the other hand, when the electromagnetic coil is disengaged, the slider, under the reaction force of the spring mounted on the ring gear, moves up along the outer wall of the ring gear to reach the first locating position. action, now the tooth groove of the lower connection piece is disengaged from the teeth of the drive frame, allowing the transmission device to enter into operating condition.
    [00117] From now on, the operating conditions of washing and rotation of the washing machine with the drive mechanism in the present patent application are explained in detail below.
    [00118] When centrifuging the laundry for washing, the electromagnetic coil in the clutch coil assembly is energized and the electromagnetic coil and the magnetic iron ring 912 on the outside of the slider form a closed magnetic path. Then the slider slides down (in the direction shown in Figure 1) along the outer wall of the ring gear under repellent magnetic force. During the sliding process, the slider compresses the spring in the sprocket and many tooth grooves in the lower connecting piece of the slider and the teeth at one end of the drive frame, thereby enabling the slider and the frame to drive are connected as one piece, and the slew tube and drive frame are connected as one piece, thus driving the tube to obtain the same rotation speed as the drive frame. Due to this, the rotational inertia of the basket connected to the slewing tube becomes greater than the rotational inertia of the rotor connected to the washing shaft, thus, the spur gear and the sprocket in the transmission device are fixedly connected by the washing shaft and the rotor in the locked state, allowing the transmission device to be locked by the large rotational inertia of the basket, then the transmission device can rotate together with the drive structure at high speed, thereby driving the washing shaft fixedly connected to the transmission device to rotate together with the drive structure at high speed, thus the basket connected with the rotating tube and the rotor connected to the washing shaft rotate at high speed, performing the centrifugation for washing clothes.
    [00119] When washing clothes that are in washing condition, the electromagnetic coil is de-energized and the closed magnetic path formed by the coil and the slider disappears and the slider is no longer under repellent magnetic force, thus under the spring reaction force , the runner moves up together with the outer wall of the sprocket, so that many tooth grooves in the lower connecting piece of the runner and the teeth of one end of the drive frame is disengaged, so it drives the sprocket piece. slider connection and the teeth at one end of the drive frame are disengaged, thus triggering the connecting device on the speed reduction mechanism to enter the operating state:
    [00120] As shown in Figure 18, when the drive frame rotates around the drive frame shaft at high speed counterclockwise (i.e., wash shaft shaft 50, as shown in Figure 18, to convenience of description hereinafter this shaft will be called washing shaft shaft) which drives the eccentric sleeve 4 which is fixedly connected to it to rotate counterclockwise and at the same high speed as the washing shaft, and rotation High speed eccentric sleeve drives spur gear to rotate eccentrically around shaft of high speed wash shaft. During high rotation of the spur gear at high speed, and with its outer teeth meshed with the inner teeth of the sprocket to interact with each other, thereby allowing the spur gear to rotate around its own axis 40 alone and the spur gear autorotation direction is opposite to the eccentric sleeve rotation direction, as shown in Figure 18, the spur gear rotation direction is clockwise and its rotation speed is less than the rotation speed of the drive frame .
    [00121] During self-rotation by the meshing between the sprocket and the sprocket, the sprocket rotates in its function, due to the differences in the teeth between the internal teeth of the sprocket and the external teeth of the sprocket, the sprocket rotates in the opposite direction to the spur gear at low speed and counterclockwise as shown in Figure 18. The slider frame on the drive device also rotates in conjunction with the spur gear autorotation. When the spur gear rotates around its own shaft clockwise at a speed less than the rotational speed of the drive frame, the sprocket transfers energy from a pair of gear groove 62 disposed above a lower guide pair 852 arranged in a pair of sliding gear slots, thereby allowing the cross slider to rotate together with the spur gear in a clockwise direction, and it drives the positioning slider where a pair of slots 863 is slidably connected to the upper guide on the cross slider to rotate clockwise. To do this, the center of the positioning slider is connected to the washing shaft, the positioning slider rotating clockwise, which triggers the washing shaft to rotate clockwise with the positioning slider and in the direction indicated by the arrow shown in Figure 18.
    [00122] As shown in Figure 18, in the washing condition, when the drive structure rotates at high speed, the transmission device in this configuration can allow the rotating tube to be connected to the sprocket and the rotor to be connected to the shaft of washing to obtain a low speed that is lower than the rotation speed of the drive structure in the opposite direction, which solves the difficulty encountered in current technology regarding the large energy consumption for fixing the washing tube during the washing mode.
    [00123] This configuration is for installing the speed reduction mechanism inside the inner rotor, which effectively utilizes the inner space of the inner rotor. It is advantageous because the size of the washing machine tends to be smaller in production. Furthermore, in this configuration, slider structure is adopted for connecting the spur gear and the washing shaft, which transfers the eccentric output of the spur gear around the shaft of the washing shaft to the output coaxially together with the washing shaft , which can prevent the speed reduction mechanism from causing unnecessary vibrations during operation.
    [00124] The second configuration of the present patent application is:
    [00125] As shown in Figures 7 and 8, is a schematic view showing the structure of the drive device of the washing machine with the structure of the connection plate.
    [00126] As shown in Figure 7, the motor in this configuration is the internal rotor of the motor. In which, the inner rotor with the empty cavity is disposed inside the housing assembly, and the speed reducing device is installed inside the empty cavity of the inner rotor and the speed reducing device comprises the transmission device and the device of clutch coil. In which, the transmission device consists of eccentric sleeve 4, sprocket 6, sprocket 7 and connecting device 8. In this configuration, the connecting device is used in the structure of the connecting plate.
    [00127] In this configuration, the housing assembly, the clutch coil device, the eccentric sleeve and the ring gear are strictly the same as in the first configuration, therefore, they will not be repeated here. Now, only the connecting device and the spur gear structure that are connected to the connecting device will be described below.
    [00128] As shown in Figure 11, spur gear 6 in this configuration includes steel ring 63 and outer teeth 60, which are located on the outside of the steel ring and are integrated integrated with the steel ring by plastic injection. Connecting holes 61 are evenly located around the steel ring for installation of one or more connecting shafts 83. The steel ring is connected by rotation to the first tube of the eccentric sleeve and the detailed connection mode is the same as for the first configuration and therefore will not be repeated here.
    [00129] The connection plate structure in this configuration includes the connection plate and many connection shafts that contact the connection plate by sliding, which drives the connection plate to rotate through frictional force. Specifically, as shown in Figures 8, 9 and 10, the connecting plate has the plate-shaped connecting plate body 81 and its center passes through the washing shaft, being fixedly connected to the washing shaft. In order to reinforce the connection with the washing shaft, it can install a cylinder tube 84 in the middle of the upper end of the body of the connection plate and can be fixedly connected to the washing shaft by the profile of teeth arranged inside the inner wall of the cylinder. During fabrication, the body of the connecting plate is mold-integrated into the cylinder, or welding can be used to integrate both as a single piece. There are several through holes 82 located evenly around the body of the connecting plate. Many connecting shafts are installed inside each hole and also come into contact with the slip through holes. Specifically, one end of each connecting shaft is inserted into a through hole of the connecting plate body along the inner wall of the through hole. The other end of each connecting shaft is fixedly disposed within the hole of the spur gear connecting shaft. In this configuration, the number of through holes of the connecting plate body and the number of connecting shafts are both six, where the inside diameter of the through hole is greater than the outside diameter of the connecting shaft. During assembly, first the other end of the six connection shafts must be fixedly installed into the holes of the six connection shafts of the spur gear, and then one end of the six connection shafts individually must be fixedly installed inside the six through holes of the body of the connection plate, and also ensure that the outer surface of the six connection axes individually are tangent to the outer wall of the six through holes in the corresponding opposite position.
    [00130] The purpose of the transmission device in this configuration is to transfer the rotational energy of the inner rotor in the following manner of operation.
    [00131] When the electromagnetic coil in the clutch coil device is energized, the washing machine enters the spin mode: At this time, the electromagnetic coil and the electromagnetic steel ring 912, arranged on the outside of the slider, form a magnetic path closed. Now the slider slides down (in the downward direction shown in Figure 1) along the outer wall of the ring gear under repellent magnetic force. During the sliding process, the slider compresses the spring in the sprocket and many tooth grooves in the lower connecting piece of the slider and the teeth at one end of the drive frame, thereby enabling the slider and the frame to drive are connected as one piece, and the slew tube and drive frame are connected as one piece, thus driving the tube to obtain the same rotation speed as the drive frame. Due to this, the rotational inertia of the basket connected to the slewing tube becomes greater than the rotational inertia of the rotor connected to the washing shaft, thus, the spur gear and the sprocket in the transmission device are fixedly connected by the washing shaft and the rotor in the locked state, allowing the transmission device to be locked by the large rotational inertia of the basket, then the transmission device can rotate together with the drive structure at high speed, thereby driving the washing shaft fixedly connected to the transmission device to rotate together with the drive structure at high speed, thus the basket connected with the rotating tube and the rotor connected to the washing shaft rotate at high speed, performing the centrifugation to wash clothes.
    [00132] When washing clothes that are in washing condition, the electromagnetic coil is de-energized and the closed magnetic path formed by the coil and the slider disappears and the slider is no longer under repellent magnetic force, thus under the spring reaction force , the runner moves up together with the outer wall of the sprocket, so that many tooth grooves in the lower connecting piece of the runner and the teeth of one end of the drive frame is disengaged, so it drives the sprocket piece. slider connection and the teeth at one end of the drive frame are disengaged, thus triggering the connecting device on the speed reduction mechanism to enter the operating state:
    [00133] As shown in Figure 18, when the drive frame rotates around the drive frame shaft at high speed counterclockwise (that is, wash shaft shaft 50, as shown in Figure 18, to convenience of description hereinafter this shaft will be called washing shaft shaft) which drives the eccentric sleeve 4 which is fixedly connected to it to rotate counterclockwise and at the same high speed as the washing shaft, and rotation High speed eccentric sleeve drives spur gear to rotate eccentrically around shaft of high speed wash shaft. During high rotation of the spur gear at high speed, and with its outer teeth meshed with the inner teeth of the sprocket to interact with each other, thereby allowing the spur gear to rotate around its own axis 40 alone and the spur gear autorotation direction is opposite to the eccentric sleeve rotation direction, as shown in Figure 18, the spur gear rotation direction is clockwise and its rotation speed is less than the rotation speed of the drive frame .
    [00134] During self-rotation by the meshing between the sprocket and the sprocket, the sprocket rotates in its function, due to the differences in the teeth between the internal teeth of the sprocket and the external teeth of the sprocket, the sprocket rotates in the opposite direction to the spur gear at low speed and counterclockwise as shown in Figure 18. Together with the spur gear autorotation, the transmission device connecting plate structure rotates in accordance with the spur gear autorotation, since it drives the wash shaft to rotate in the same direction and speed as the spur gear, moreover, it transfers the eccentric output resulting from the eccentric rotation of the spur gear around the wash shaft shaft to the output resulting from the axial rotation of the spur gear along the wash shaft.
    [00135] Specifically, during eccentric rotation of the spur gear, the six connecting shafts fixedly mounted in the holes of the six connecting shafts of the spur gear, rotate in synchronism with it. As the other end of the six connection shafts fixed against the inner wall of the six holes in the connection plate body, also rotating circularly within the inner wall, the six connection shafts drive the connection plate body to rotate in sync with the spur gear rotation. However, the cylindrical tube on the upper end surface of the connecting plate body is fixedly connected to the washing shaft, when the connecting plate body rotates, it drives the washing shaft to perform synchronized rotation. In this way, making it possible to transfer the output resulting from the eccentric rotation of the spur gear deviated from the washing shaft shaft to the output in the same axial direction as the washing shaft.
    [00136] As the structure of the other parts mentioned in the configuration of this patent application is composed of the same structure as the first configuration, and the theory of operation is also the same, it will not be repeated hereinafter.
    [00137] For the drive device of the washing machine in this patent application, in order to avoid longitudinal play or displacement of the washing shaft in the axial direction, several locking rings or other components that have the same function as the ring locks will be added at the proper position of the wash shaft or swing tube as mentioned above in the first configuration and in the second configuration; !For convenience purpose for installation and load resistance, washer, or other components that have the same function as the washer, should be added in the proper position of the drive shaft; / To re-start the standard transmission reaction and assembly of the present patent application, many bushings and many ball bearings should be positioned in different sections, such as installing multiple bushings between the wash shaft and swing tube, and installation of many ball bearings between the sprocket and the slewing tube, the mounting plate and the slewing tube and the motor end cover and the wash shaft, specifically, the above mentioned ball bearings can be deep spherical bearings grooved. Preferably, the Sleeve can be installed between the ball bearing located between the motor cover and the washing shaft, the washing shaft having the function of bushing. To prevent the wash water from penetrating inside the gearbox and motor along the wash shaft, swing tube and mounting plate, a small seal is installed between the wash shaft and swing tube, already a large seal is installed between the swing tube and the mounting plate. Preferably, in order to reduce vibration and reduce noise during operation, a damping pad made of plastic material or flexible material should be added between the assembly parts, and under the condition of achieving the assembly strength or related functions, the housing assembly uses cast aluminum material or ring gear uses plastic material.
    [00138] Therefore, the locking ring, washer, bushing, ball bearing, sleeve, large seal, small seal, and vibration and noise damping pad, etc., all these parts are considered normal used by the individual skilled in the field Therefore, some modifications and improvements that can be made in the structure of the parts mentioned above in the present patent application should not be considered as an innovation of this patent.
    [00139] In addition to the two additional configurations, the gear reducer mechanism can have other configurations. The present application also provides for a washing machine including a gear reducing mechanism in the first configuration or second configuration of the present application, a washing machine using one of the gear reducing mechanisms, and in the second configuration of the present application. patent, has compact structure and small volume, being convenient for manufacturing products with reduced dimensions.
