Fig. 6 demonstrates the starting state figure of the starting state of the embodiment of the invention.
As shown in Figure 6, the inner peripheral surface of above-mentioned union body 85 is provided with zigzag projection 86, zigzag projection 72 engagements of the zigzag projection 58` of above-mentioned zigzag projection 86 and above-mentioned drive division 58 and dehydrating shaft 70.Also be provided with a plurality of fixed lobes 87.The effect of said fixing projection 87 is: increase the contact area between plug-in module portion 88 and the union body 85, make between plug-in module portion 88 and the union body 85 to firmly fix.
By above-mentioned plug-in module portion 88 above-mentioned union body 85 and movable yoke 81 are connected.That is to say, be positioned at above-mentioned union body 85 under the state of above-mentioned movable yoke 81 inside, carry out the plug-in module operation, form above-mentioned plug-in module parts 88.Finish the formation of above-mentioned movable connector 80 by said process.
On the one hand, the upper end of above-mentioned movable connector 80 is provided with support slot 89, and above-mentioned support slot 89 supports the lower end of above-mentioned spring 80`, and above-mentioned support slot 89 is formed on the above-mentioned plug-in module parts 88.
In addition, be provided with drive unit solenoid 90 below the above-mentioned bearing shell 30, above-mentioned solenoid 90 is used to drive above-mentioned movable connector 80.Apply power supply to above-mentioned solenoid 90, the elastic force that above-mentioned movable connector 80 overcomes above-mentioned spring 80` moves to top, and the zigzag projection 86 of above-mentioned union body 85 and the zigzag projection 58` of above-mentioned drive division 58 are separated.
The upper end of above-mentioned solenoid 90 has first yoke plate 92, and the lower end of above-mentioned solenoid 90 possesses second yoke plate 94 is arranged.On the one hand, be provided with jog 95 below above-mentioned second yoke plate 94, above-mentioned jog 95 and jog 83 are fixed, and above-mentioned jog 83 is formed on the fixed flange 82 of above-mentioned movable connector 80.
Below, the effect of the power transmission of washing machine of the present invention with said structure is elaborated.
At first, the power formation that transmits by the power transmission with said structure formation is elaborated.The revolving force that is used to drive washing machine is to produce under the electro permanent magnetic of said stator 40 and rotor 50 interacts.
The rotation of above-mentioned rotor 50 is rotated above-mentioned drive division 58, and the engagement of the zigzag projection 59 by above-mentioned drive division 58 and the zigzag projection 62 of wash shaft 60 transmits revolving forces to above-mentioned wash shaft 60.By the rotation of above-mentioned wash shaft 60, make the washing fin of the sink inside, upper end that is formed on above-mentioned wash shaft 60 be rotated, overturn washings and washings.
At this moment,, apply power supply, make above-mentioned movable connector 80 relative to moving to top to above-mentioned solenoid 90 in order only to allow above-mentioned wash shaft 60 be rotated individually.The elastic force that overcomes above-mentioned spring 80` by above-mentioned movable connector 80 moves to top, and above-mentioned jog 83 is engaged on the jog 95 of above-mentioned second yoke plate 94.
In addition, to the moving of top, the zigzag projection 86 that the zigzag projection 58` with above-mentioned drive division 58 is meshed together can further not mesh with above-mentioned zigzag projection 58` by above-mentioned movable connector 80.So the revolving force of above-mentioned rotor 50 can not be sent on the above-mentioned movable connector 80, the above-mentioned dehydrating shaft 70 that meshes with above-mentioned movable connector 80 is not rotated.Fig. 2 demonstrates aforesaid state.
On the one hand, for example, washings is carried out dehydration, need above-mentioned wash shaft 60 and dehydrating shaft 70 to be rotated at high speed simultaneously for above-mentioned sink is rotated.So, start above-mentioned solenoid 90.By the startup of above-mentioned solenoid 90, above-mentioned movable connector 80 is relatively moved downwards by above-mentioned spring 80` resiliency urged.
So, as shown in Figure 6, the upper end of the zigzag projection 86 of the union body 85 of above-mentioned movable connector 80 and 72 engagements of the zigzag of above-mentioned dehydrating shaft 70 projection, the zigzag projection 58` engagement of the lower end of above-mentioned zigzag projection 86 and above-mentioned drive division 58.
Under above-mentioned state, the power of above-mentioned rotor 50 transmits to above-mentioned wash shaft 60 and movable connector 80 by above-mentioned drive division 58, sends above-mentioned dehydrating shaft 70 to through above-mentioned movable connector 80.Through said process, above-mentioned wash shaft 60 and dehydrating shaft 70 are rotated simultaneously.
