BACKGROUND

[0002] As a kind of household appliance, washing machine gradually becomes an indispensable part in people's life, and full-automatic pulsator washing machine as a kind of main washing machine type, its application range is also more and more widely. The working mode of the existing full-automatic pulsator washing machine is generally as follows: during washing and rinsing, the driving device drives the pulsator of the washing machine to rotate forward and reverse through the deceleration clutch device; during dehydration, the driving device drives the pulsator and the washing barrel of the washing machine to rotate synchronously at high speed through the deceleration clutch device.

[0003] In order to realize the switching of different transmission modes under washing and dehydration conditions, a movable clutch sleeve needs to be installed on the deceleration mechanism of the deceleration clutch, and the transmission mode of the transmission gear train in the deceleration mechanism is changed by moving the clutch sleeve, so that the power input by the input shaft of the deceleration clutch is transmitted to the output shaft, the output shaft sleeve and other components, to realize controllable driving rotation of the pulsator and the inner barrel respectively, and then the washing and dehydration switching effect of the washing machine is achieved.

[0004] The clutch mechanism needs to be installed on the deceleration clutch, and the clutch arm of the clutch mechanism needs to pass through the installation channel provided on the motor stator, so that the two ends of the clutch arm are connected with the clutch sleeve in the inner circumferential space of the motor stator and the traction motor outside the motor respectively, so as to realize the transmission of traction action to the clutch sleeve and achieve the effect of clutch driving control of the deceleration clutch.

[0005] However, since the clutch arm needs to protrude from the motor, the components installed in the lower space of the outer barrel of different washing machine models are different, and in order to adapt to different washing machine models, the motor needs to be changed in installation direction, so that the installation channel provided on the motor is oriented in different directions, so that the clutch arm and other washing machine components are staggered, so as to realize the installation effect of the deceleration clutch. The above installation method needs to change the installation direction of the motor, especially the motor stator, which changes the wiring mode of the power supply line connected with the stator, greatly affecting the assembly rate of the deceleration clutch on different washing machines; and the power supply line connected with the motor in different installation directions may be too long or too short, which may cause certain safety hazards to the washing machine.

The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] As shown in FIG. 1 to FIG. 8, the embodiment of the present application introduces a washing machine deceleration clutch, which comprises a motor 100, a deceleration mechanism 200, a clutch mechanism 300 and a mounting plate 400; the deceleration mechanism 200 is mounted on the mounting plate 400, the clutch mechanism 300 and the motor 100 are mounted on the deceleration mechanism 200; of course, the clutch mechanism 300 can also be mounted on the motor 100, the motor 100 can be mounted on the mounting plate 400, the clutch mechanism 300 can be mounted on the mounting plate 400, and so on.

[0050] In the embodiment of the present application, a washing machine is also introduced, which comprises an outer barrel, the barrel shaft of the outer barrel is vertically arranged, the upper end is open, and the lower end is closed to form the outer barrel bottom; a rotatable inner barrel is sleeved in the outer barrel, the inner barrel wall is arranged with a dehydration hole for connecting the inner and outer barrels, so that the water separated from the clothes in the inner barrel can flow out through the dehydration hole, and the effect of separating the clothes from the water is realized; at the same time, a stirring component relatively rotatable around the shaft is arranged in the inner barrel, for example, a pulsator arranged above the inner barrel bottom, a stirring column in the inner barrel, etc. At the same time, the above-mentioned assembled washing machine deceleration clutch is integrally assembled to the lower side of the outer barrel bottom of the above-mentioned washing machine, the mounting plate is arranged upward, and the mounting plate is fixedly installed between the mounting plate and the outer barrel bottom of the washing machine, so as to realize the purpose of installing the washing machine deceleration clutch on the outer barrel of the washing machine. The output shaft 203 of the above-mentioned deceleration clutch extends into the outer barrel and is connected with the stirring component such as the pulsator, so as to drive the stirring component to rotate and realize the stirring effect on the clothes and water for washing treatment.

[0051] At the same time, in the embodiment of the present application, the above-mentioned motor 100, deceleration mechanism 200, clutch mechanism 300 and mounting plate 400 can be any structure of the existing deceleration clutch, and the present application is suitable for the modification of any model of the existing washing machine deceleration clutch, so that the existing washing machine deceleration clutch can be adapted to more models of the pulsator washing machine.

[0052] In the embodiment of the present application, the mounting plate 400 is arranged at the uppermost part of the deceleration clutch, the mounting plate 400 is provided with a horizontally extending and upwardly recessed strip-shaped groove 401, the groove bottom of the strip-shaped groove 401 is provided with a through hole penetrating upward and downward; at least part of the deceleration mechanism 200 is arranged in the strip-shaped groove 401, so that the installed deceleration clutch utilizes the above-mentioned strip-shaped groove 401 to at least partially coincide with the height of the outer barrel bottom, thereby reducing the occupied height of the installed washing machine deceleration clutch.

[0053] In the embodiment of the present application, the speed reduction mechanism 200 comprises a speed reducer housing 201, which is generally vertically extended in a cylindrical shape. The upper and lower ends of the cylindrical speed reducer housing 201 are respectively provided with an output shaft 203 and an input shaft 202 coaxially inserted into the housing. The output shaft 203 extends from the through hole of the mounting plate 400 to the upper portion to extend into the outer drum of the washing machine, so as to realize the assembly of the output shaft 203 and the stirring components such as the pulsator in the outer drum. The input shaft 202 extends to the lower portion and is coaxially fixedly connected with the rotor of the motor 100, so as to realize the rotation of the input shaft 202 driven by the rotor of the motor 100. The speed reducer housing 201 is internally provided with a transmission gear train, which can be any transmission gear train structure of the prior art. The transmission gear train is in transmission connection between the input shaft and the output shaft, so as to transmit the rotation of the input shaft 202 to the output shaft 203, drive the stirring components such as the pulsator of the washing machine to rotate around the shaft through the output shaft 203, and further achieve the effect of stirring the water and clothes in the outer drum of the washing machine for washing treatment.

[0054] At the same time, in order to realize the dehydration function of the washing machine, an inner drum which can rotate around the shaft is arranged in the outer drum. The dehydration hole is arranged on the inner drum, and the stirring structure such as the pulsator is mounted in the inner drum. When the washing machine performs the dehydration program, the inner drum and the stirring structure such as the pulsator rotate coaxially and at the same speed. The water on the clothes in the drum is separated by the centrifugal force and flows to the outer drum and then is discharged. In order to realize the rotation of the inner drum, the output shaft sleeve can be sleeved on the output shaft 203. The output shaft sleeve is coaxially connected with the inner drum, so as to realize the clutch transmission between the input shaft 202 and the output shaft 203 and / or the output shaft sleeve through the transmission gear train in the speed reducer housing 201, so that the rotation power input by the motor drives the inner drum and the pulsator to rotate at the same speed, and the realization of the working condition that the pulsator rotates alone.

[0055] In order to switch the transmission mode of the transmission system in the washing and dehydration conditions, a movable clutch sleeve 302 is installed on the speed reduction mechanism 200, and the transmission mode of the transmission system in the speed reduction mechanism 200 is changed by moving the clutch sleeve 302, so that the power input by the input shaft 202 is transmitted to the output shaft 203 and / or the output shaft sleeve, thereby achieving the switching effect of the washing machine in the washing and dehydration conditions. At the same time, in order to drive the clutch sleeve 302 to move, a clutch mechanism 300 is installed on the speed reduction clutch, and the clutch mechanism 300 is generally installed on the speed reducer housing 201 of the speed reduction mechanism 200. The clutch mechanism 300 includes a clutch arm 301, which is rotatably installed on the speed reducer housing 201. One end of the clutch arm 301 is connected to the clutch motor, and the other end is provided with a yoke 3013 which can move the clutch sleeve 302. The clutch arm 301 is hinged to the speed reducer housing 201, and a torsional spring 304 is arranged at the hinge to drive the clutch arm 301 to remain in the initial position, and the yoke 3013 drives the clutch sleeve 302 to the initial position. At this time, the transmission system of the speed reduction mechanism 200 is in the first transmission state, and the washing machine can be in the washing or dehydration condition. The clutch arm 301 is also connected to the traction motor, and the output action of the traction motor overcomes the restoring force of the torsional spring 304 to drive the clutch arm 301 to rotate and move to the clutch position. At this time, the transmission system of the speed reduction mechanism 200 is in the second transmission state, and the washing machine can be in the dehydration or washing condition.

[0056] Since the existing clutch sleeve 302 is sleeved on the input shaft 202 of the speed reduction mechanism 200, the clutch sleeve 302 needs to be arranged inside the stator 101 of the motor 100. The space inside the motor stator 101 is small, and the traction motor of the clutch mechanism 300 needs to be powered. Therefore, the traction motor needs to be arranged outside the motor 100, and the clutch arm 301 needs to pass through the stator 101 of the motor 100 to transmit the driving control force of the traction motor to the clutch sleeve 302 inside the stator 101, so as to move the clutch sleeve 302 and change the transmission state of the transmission system of the speed reduction mechanism 200.

[0057] In this application, in order to adapt to different washing machine models, the clutch mechanism 300 of the speed reduction clutch needs to be reversibly installed in different radial directions of the motor 100. At the same time, since the power supply line of the motor 100 is connected to the stator 101, in order to avoid changing the direction of the power supply line of the motor 100, the installation direction of the motor 100 needs to be relatively fixed, and the stator 101 of the motor 100 needs to be installed on the speed reducer housing 201 of the speed reduction mechanism 200 in a constant direction. In order to achieve the above-mentioned application purposes, the technical solutions adopted by the present application are as follows:

[0058] As shown in FIGS. 1-7, in the embodiment of the present application, the deceleration clutch is provided with a plurality of installation positions, and the clutch mechanism 300 can be selectively installed at any of the installation positions; each of the installation positions is at a different radial direction of the stator 101 of the motor 100, so that the clutch mechanism 300 can be installed at different radial directions of the stator 101 of the motor 100, and the installed clutch mechanism 300 can be adapted to different washing machine models and assembled with other components of different washing machine models.

[0059] Through the above arrangement, the clutch mechanism 300 of the washing machine deceleration clutch is selectively installed at different directions, so that the clutch mechanism 300 installed at a selected position can be adapted to different washing machine models under the premise that the installation direction of the motor 100 is fixed, thereby achieving the effect of significantly improving the adaptability of the deceleration clutch.

[0061] In the embodiment of the present application, each installation channel 102 extends along a different radial direction of the annular stator 101, so that the clutch structure 300 can be arranged along different radial directions of the annular stator 101, allowing the clutch structure 300 to be selectively installed in different radial directions, thereby allowing the clutch structure 300 to be adapted to different models of washing machines, and avoiding components in different directions below the bottom of the outer barrel, effectively improving the adaptability of the speed reduction clutch.

[0062] Further preferably, an installation channel 102 is arranged on each of the opposite sides of the stator 101 of the motor 100, namely a first installation channel 1021 and a second installation channel 1022. The two installation channels 102 are respectively arranged towards the opposite left and right sides of the strip-shaped groove 401 of the mounting plate 400, so that the clutch mechanism 300 has at least two installation positions arranged on the left and right opposite sides, allowing the clutch mechanism 300 to be installed on the left or right side of the outer barrel axis of the washing machine, thereby greatly improving the assembly adaptability of the speed reduction clutch.

[0063] Preferably, the strip-shaped groove 401 arranged on the mounting plate 400 is a horizontally extending upwardly recessed groove structure with one end closed and one end open.

The first installation channel 1021 and the second installation channel 1022 on the annular stator 101 are respectively arranged towards the left and right corner of the closed end of the strip-shaped groove 401, so that the two installation channels 102 are respectively arranged obliquely, allowing the clutch arm 301 selectively installed thereon to extend along the diagonal direction of the mounting plate, thereby allowing the part of the clutch arm 301 protruding from the motor 100 to be entirely below the mounting plate 400, so that the overall outer peripheral dimension of the speed reduction clutch does not exceed the outer peripheral contour of the mounting plate 400, thereby reducing the occupied volume of the speed reduction clutch.

[0064] In addition, the radial dimension of the speed reducer housing 201 of the speed reduction mechanism 200 is smaller than the left-right width of the strip-shaped groove 401 of the mounting plate 400, so that the upper part of the speed reducer housing 201 is in the strip-shaped groove 401. At the same time, a radially protruding mounting plate 400 is arranged at the middle part of the speed reducer housing 201. The left-right width of the mounting plate 400 is greater than the left-right width of the strip-shaped groove 401 and smaller than the left-right dimension of the mounting plate 400, so that the left and right sides of the mounting plate 400 are respectively correspondingly attached to the mounting plate part of the periphery of the strip-shaped groove 401 and are fixedly installed by screws, rivets or other structures, allowing the speed reduction mechanism 200 to be firmly fixed and assembled with the mounting plate 400.

[0067] Further preferably, in the embodiment of the present application, the mounting seat 303 can be integrally arranged with the reducer housing 201, so as to reduce the number of components of the speed reduction clutch and improve the integrity of the speed reduction clutch.

[0072] Through the above arrangement, the upper part of the annular stator 101 is provided with a plurality of radially arranged through openings, each through opening separates different positions of the mounting portion 103 provided at the upper end of the annular stator 101, so that the mounting portion 103 is independently separated and matched with the lower end surface of the reducer housing 201 assembled by the end surface to jointly form the installation channel 102, which effectively ensures the radial dimension of the installation channel 102 through which the clutch arm 301 passes, and avoids the occurrence of situations such as interference between the clutch arm 301 and other components and inability to effectively clutch.

[0073] At the same time, each independent part of the mounting portion 103 separated by each through opening is fixedly connected with the reducer housing 201, so that the installation strength can be ensured when the clutch arm 301 is selectively installed in different installation channels 102, and the torsional resistance of the assembly of the clutch arm 301 is effectively improved.

[0074] Preferably, in order to improve the convenience of assembly between the motor 100 and the speed reduction mechanism 200, at least one positioning column protruding upward can be arranged on the mounting end surface 1032 of the mounting portion 103, and a matching positioning groove recessed upward can be arranged on the lower end surface of the speed reducer housing 201 of the speed reduction mechanism 200, so that the annular stator 101 is quickly positioned with the speed reducer housing 201 through the positioning column and the positioning groove, and the annular stator 101 can be assembled and fixed with the speed reducer housing 201 in a constant orientation, thereby ensuring that the orientation of the assembled motor 100 is constant, the power supply line of the motor 100 can be extended in a fixed manner, and further preventing the power supply line of the motor 100 from being randomly arranged.

[0075] In the embodiment, the clutch mechanism 300 includes a clutch arm 301, which is arranged through the mounting passage 102 arranged on the stator 101; one end of the clutch arm 301 extending into the inner circumference of the stator 101 is provided with a yoke 3013, which is in contact with a clutch sleeve 302 sleeved on the input shaft 202; the middle part of the clutch arm 301 is hingedly connected with a mounting seat 303 through a horizontal rotating shaft 305, and a torsional spring 304 is arranged at the hinge connection, and the two ends of the torsional spring 304 are respectively in abutment with the clutch arm 301 and the speed reduction mechanism 200, for pushing the clutch arm 301 to remain in or move to the initial position; one end of the clutch arm 301 outside the stator 101 is connected with a traction motor, and is driven to rotate around the shaft by the traction motor, thereby driving the yoke 3013 and the clutch sleeve 302 to move up and down, so that the engagement relationship between the clutch sleeve 302 and the transmission gear train of the speed reduction mechanism 200 changes, thereby realizing the effect of changing the rotating mode of the output shaft 303 and / or the output shaft sleeve.

[0076] In the embodiment, the speed reduction mechanism 200 includes a speed reducer housing 201, a transmission gear train composed of speed reduction gears is arranged in the speed reducer housing 201; an input shaft 202 is arranged to pass through one end of the speed reducer housing 201, and an output shaft 203 is arranged to pass through the other end; the annular stator 101 of the motor 100 is fixedly installed on one side of the speed reducer housing 201 and coaxially arranged on the periphery of the input shaft 202; the connection part between the stator 101 and the speed reducer housing 201 is provided with mounting passages 102 respectively arranged in different radial directions, and the yoke 3013 of the clutch arm 301 extends into the inner circumferential space of the stator 101 through the selected mounting passage 102 and abuts against the clutch sleeve 302.

[0077] In the embodiment, the mounting channel 102 is gradually narrowed in width from the side where the stator 101 is mounted to the free side in the up-down direction, that is, the mounting channel 102 is gradually narrowed in width from the upper side to the lower side; the part of the clutch arm 301 passing through the mounting channel 102 is arranged to have the same width as the narrowest part of the mounting channel 102, so that the left and right side walls of the mounting channel respectively provide left and right direction limiting for the rotation of the clutch arm 301, especially when the clutch arm 301 generates a clamping action to the lowermost side of the mounting channel 102, the clutch arm 301 is guided and limited by the narrowest part of the mounting channel 102, effectively avoiding the left and right deflection of the clutch arm 301.
