The structures of different conditions connects, such as rotational structure and fixed structure, and ring gear 4 be it is axial static, such ring gear 4 it is close
What envelope became is more easier, and the requirement to machining accuracy will not be too high, so that processing cost is reduced, if ring gear 4 is axial sliding
It is dynamic, it is higher to the seal request being slidably connected, so, setting one can slide completion and different shapes in the axial direction in the present invention
The clutch axle sleeve 21 of the structure connection of state, completes the function of clutch, meanwhile, ring gear 4 and clutch can be driven in internal circumferential
Axle sleeve 21 has identical rotary state.
Embodiment five
In the present embodiment, the both ends of clutch axle sleeve 21 are respectively equipped with end-tooth 5, and clutch axle sleeve 21 is in clutch driving unit
It is axially movable under effect, so that clutch axle sleeve 21 can be at first position and the second position.
When the state of first position, the end-tooth 5 of 21 one end of clutch axle sleeve is connect with a rotational structure, clutch axle sleeve 21 with turn
The synchronized rotation in the same direction of son 6, this state is dewatering state；
When the second position, the end-tooth 5 of 21 other end of clutch axle sleeve is connect with a fixed structure, and clutch axle sleeve is fixed, this
State is washing state.
It is also possible that making clutch axle sleeve 21 be in the third place under clutch driving unit effect.When the third place state,
The end-tooth 5 at 21 both ends of clutch axle sleeve is not connected with other structures, and clutch axle sleeve 21 is made to be in free state, this state one
As also be washing state.
The rotational structure can be the rotor 6 or and the relatively-stationary clutch discs 13 of rotor 6 of direct driving motor；
The fixed structure can be outer cylinder or shell 19 or and the relatively-stationary fixed disk of shell 19.
The speed-reducing clutch is fixedly mounted on outer cylinder/bucket of washing machine through shell, deceleration device and at least partly from
It attaches together and is arranged in shell.The shell includes 14 and of shell set on deceleration device and at least partly arrangement of clutch periphery
Upper cover set on 14 one end of shell.The upper cover is mutually fixedly connected respectively with outer cylinder/bucket and shell 14；Preferably, on described
Lid is made of mounting plate 8.
Mounting plate 8 is equipped with tooth socket 9 corresponding with the end-tooth 5 of clutch axle sleeve 21, the end face of the clutch axle sleeve 21
Tooth 5 protrudes into corresponding tooth socket 9, and mounting plate 8 and clutch axle sleeve are directly connected to, this kind of connection type, and structure is simple, assembly is simple,
Components are less, save the cost；Or a fixed disk (fixed disk is being not shown in the figure), the fixed disk are set on mounting plate 8
It is equipped with tooth socket 9 corresponding with the end-tooth 5 of clutch axle sleeve, the end-tooth 5 of the clutch axle sleeve protrudes into corresponding tooth socket 9,
Mounting plate 8 and clutch axle sleeve 21 are indirectly connected with, this kind of connection type is more advantageous to the service life of mounting plate, if clutch axle sleeve is logical
The tooth socket 9 crossed on end-tooth 5 and mounting plate 8 is directly connected to, and since torque is larger in rotation process, after tooth socket 9 damages, needing will be whole
A mounting plate is all replaced, if being connected by the tooth socket 9 in fixed disk, after the tooth socket 9 in fixed disk damages, can only be replaced
Fixed disk, the maintenance of such washing machine in the future become more convenient.
The rotor 6 of direct driving motor is equipped with tooth socket 9 corresponding with the end-tooth 5 of clutch axle sleeve, the clutch axle sleeve

Another location on to axial direction, when clutch platen 20 continues to rotate or rotates backward, the highest point of the first wedge-shaped protrusion 27 with
When the minimum point contact of the second wedge-shaped protrusion 28, clutch axle sleeve 21 is returned to home position.
This kind of clutch driving unit, structure is simple, axially occupies little space, to reduce the whole high of speed-reducing clutch
It is bigger for outer barrel/cylinder, increase washing capacity, so that subtracting in the case where washing capacity is constant to leave more space settings for degree
The volume of small washing machine, or increase washing capacity in the case where washing machine constancy of volume.
Clutch driving unit further includes a reset spring 18, the clutch platen 20 and the setting of the reset spring 18 from
The periphery of sympodium set 21 is at least partly overlapped with projection of the ring gear 4 on speed-reducing clutch axis, outside the clutch axle sleeve 21
Wall is equipped with annular boss 17, and the side of annular boss 17 is arranged in clutch platen 20, and reset spring 18 is arranged in annular boss
The other side or the clutch platen 20 and reset spring 18 the same side of annular boss is set.
Clutch platen 20 and reset spring 18 can also be separately positioned on the two sides of annular boss 17, when 20 turns of clutch platen
Dynamic, when the highest point contact of the highest point of the first wedge-shaped protrusion 27 and the second wedge-shaped protrusion 28, the other end of clutch platen 20 will
Clutch axle sleeve 21 is expressed to the another location in axial direction, and reset spring 18 is compressed, when clutch platen 20 continues to rotate or instead
To rotation, when the minimum point contact of the highest point of the first wedge-shaped protrusion 27 and the second wedge-shaped protrusion 28, clutch platen 20 is to clutch
The extruding force of axle sleeve 21 disappears, and 18 restoring force of reset spring makes clutch axle sleeve 21 be returned to home position.
Certain clutch platen 20 and reset spring 18 also can be set in the same side of annular boss 17, and clutch platen 20 squeezes
When pressing annular boss 17 to drive clutch axle sleeve 21 mobile, 18 under tension of reset spring, when clutch platen 20 is to clutch shaft
When the extruding force of set 21 disappears, 18 restoring force of reset spring makes clutch axle sleeve 21 be returned to home position.
The speed-reducing clutch is fixedly mounted on outer cylinder/bucket of washing machine through shell, deceleration device and at least partly from
It attaches together and is arranged in shell.The shell includes 14 and of shell set on deceleration device and at least partly arrangement of clutch periphery
Upper cover set on 14 one end of shell.The upper cover is mutually fixedly connected respectively with outer cylinder/bucket and shell 14；Preferably, on described
Lid is made of mounting plate 8.
As shown in Figure 6 and Figure 8, the support construction is shell 19, and the shell 19 is set close to the inside of 1 one end of input shaft
There is the second wedge-shaped protrusion 29 with the cooperation of the first wedge-shaped protrusion 27 and reversed dip on clutch platen 20, reset spring 18
