Below with reference to the accompanying drawings clutch 100 according to embodiments of the present invention is described.
With reference to shown in Fig. 1 and Fig. 2, clutch 100 according to embodiments of the present invention can include ratchet 2 and shift fork 1.
Specifically, ratchet 2 is provided with multiple along its circumferentially-spaced tooth 23 for opening arrangement, shift fork 1 be provided be suitable to respectively with tooth
23 the first ratchets 11 and the second ratchet 12 coordinated, the first ratchet 11 and the second ratchet 12 are arranged spaced apart, and the first spine
Pawl 11 is fixedly linked with shift fork 1, and the second ratchet 12 is movably connected with 1 shift fork 1.
In other words, shift fork 1 is provided with the first ratchet 11 and the second ratchet 12, and the first ratchet 11 and the second ratchet 12 are along ratchet
2 circumference, which separates, to be configured and adapted to be connected with ratchet 2.Ratchet 2 is provided with multiple teeth 23, and multiple teeth 23 are along ratchet
2 are provided at circumferentially spaced, and the end of first ratchet 11 can be inserted between the adjacent tooth 23 of any two of ratchet, the second spine
The end of pawl 12 can be inserted between other two adjacent teeth 23 of ratchet 2.First ratchet 11 is fixedly connected with shift fork 1,
Second ratchet 12 with shift fork 1 is movable is connected, so as to reduce the assembly space of shift fork 1 and ratchet 2, save clutch
100 space-consuming.
Clutch 100 according to embodiments of the present invention, the first ratchet 11 are fixedly connected with shift fork 1, the second ratchet 12 and shift fork
1 is movable connected, so as to save the assembly space of shift fork 1 so that the structure of clutch 100 is compacter.Reduce clutch
The space-consuming of device 100, and then the volume of washing machine can be reduced.
In some embodiments of the invention, line, the second ratchet 12 of the end of the first ratchet 11 and the center of ratchet 2
End and ratchet 2 center line not on the same line.The line at the end of the first ratchet 11 and the center of ratchet 2,
The line at the end of the second ratchet 12 and the center of ratchet 2 is not on the same line.That is, the first ratchet 11 and
The line at the center of the line at the center of one ratchet 21, the second ratchet 12 and the second ratchet 22 is not on the same line.I.e.
The junction of one ratchet 11 and the second ratchet 12 and ratchet 2 can not be radially relative.So as to ensure shift fork 1 and spine
The assembly space that shift fork 1 and ratchet 2 can be saved while mating connection of wheel 2 so that the structure of clutch 100 is more stepped up
Gather.
In some embodiments of the invention, line, the second ratchet 12 of the end of the first ratchet 11 and the center of ratchet 2
The angle that is limited of line at center of end and ratchet 2 can be α, 120 ° of α ＜.Thus, it is ensured that shift fork 1 with
The stability and reliability of the mating connection of ratchet 2, while can further save the space-consuming of shift fork 1.
In some embodiments of the invention, as shown in figure 1, the first ratchet 11 may be provided in the end of shift fork 1, the second ratchet
12 are located at the middle part of shift fork 1.First ratchet 11 and the second ratchet 12 are put and the first ratchet along circumferentially-spaced open up of ratchet 2
11 are located at the top of the second ratchet 12, pass through the cooperation of the first ratchet 11 and the first ratchet 21, the second ratchet 12 and second
The positioning to ratchet 2 and clutch spring can be achieved in the cooperation of ratchet 22.
In some examples of the present invention, mounting post 13, axis of second ratchet 12 around mounting post 13 can be provided with shift fork 1
It is rotatably arranged in mounting post 13.Thus the first ratchet 11 and shift fork 1 can be realized to be fixedly connected, the second ratchet 12 with
The movable connection of shift fork 1, so as to further save assembly space.Alternatively, clutch 100 can also include bullet
Property part (not shown), elastic component are located between the ratchet 12 of mounting post 13 and second to be driven when the second ratchet 12 is movable
Second ratchet 12 resets.So, when the stress of the second ratchet 12 is excessive, the second ratchet 12 can be stirred along the circumference of ratchet 2,
Spring can provide cushioning effect power to the second ratchet 12, and can reset the second ratchet 12.So as to avoid due to stress mistake
Cause the damage of the second ratchet 12 and ratchet 2 greatly, while can also save the assembly space of shift fork 1.
The present invention some examples in, the first ratchet 11 can with the integrated injection molding of shift fork 1, so as to improve the first ratchet
11 structural strength, the assembler of clutch 100 is reduced, improve the structural strength of shift fork 1, can also save the dress of shift fork 1
With space.
In addition, the invention also provides a kind of washing machine of the clutch 100 with above-described embodiment.
Because clutch 100 according to the above embodiment of the present invention has above-mentioned technique effect, therefore, the embodiment of the present invention
Washing machine also has an above-mentioned technique effect, i.e., washing machine according to embodiments of the present invention, by setting above-mentioned clutch 100,
Assembly space of the clutch 100 in washing machine internal can be saved, reduce the volume of washing machine, with facilitate the movement of washing machine and
Carry.
In some embodiments of the invention, washing machine can also include input shaft, dehydrating shaft, clutch cover and embrace spring, input
Clutch cover and dehydrating shaft are arranged on axle, spring anchor ear is embraced and is connected in clutch cover with dehydrating shaft and with ratchet.Specifically, clutch cover
It is set on input shaft, embraces spring and be connected with clutch cover and dehydrating shaft.Thus, when washing machine is dehydrated, embraces spring and hold clutch tightly
Cover and be connected with dehydrating shaft, so as to drive dehydrating shaft to rotate.When washing machine is washed, embrace spring can into relaxed state,
Dehydrating shaft is not driven rotation.
Alternatively, embracing spring both ends can be connected with two ratchets respectively, and the first ratchet 11 and the second ratchet 12 of shift fork 1 are distinguished
It is connected with two ratchets.Specifically, ratchet 2, which is located at, embraces on the outside of spring and is connected with embracing spring, and ratchet 2 can include the first ratchet
21 and second ratchet 22, it is respectively equipped with the first ratchet 21 and the second ratchet 22 multiple along its circumferentially-spaced tooth for putting of opening up
23, the first ratchet 21 and the second ratchet 22 are connected with the axial both ends of armful spring and are distributed setting along the axial direction for embracing spring respectively.
When first ratchet 11 and the second ratchet 12 are connected with the first ratchet 21 and the second ratchet 22 respectively, spring is embraced in release shape
When state, the first ratchet 11 and the second ratchet 12 separate with the first ratchet 21 and the second ratchet 22 respectively, embrace spring and recover locking
State.So as to which washing and the dehydrating function of washing machine can be realized.
Other compositions of washing machine according to embodiments of the present invention and operation are all for those of ordinary skills
Know, be not detailed herein.
