The drive device and washing machine S of the washing machine S according to the utility model embodiment are described below with reference to Fig. 1-Fig. 8.
As Figure 1-Figure 8, the drive device of the washing machine S according to the utility model embodiment, washing machine S has washing
State and dewatering state, drive device include：It is equivalent operation number of poles can controlled change pole-changing motor 300 and be suitable to distinguish laundry
The controller 400 of program.
Specifically, pole-changing motor 300 has various equivalent operation numbers of poles.It should be noted that at pole-changing motor 300
When equivalent operation number of poles running status higher, the rotating speed of pole-changing motor 300 is relatively slow but can produce larger torque；Work as pole-changing
When motor 300 is in relatively low equivalent operation number of poles running status, the torque of pole-changing motor 300 is smaller but rotating speed is larger.
It is worth understanding, the number of poles of pole-changing motor 300 described here refers to the pole pair of the rotor of pole-changing motor 300
Number.Because magnetic pole is that N poles, S extremely occur in pairs, so the number of poles of pole-changing motor 300 can be 2 poles, 4 poles, 6 poles, 8 poles etc.
Deng.From the relation of the number of poles of the rotating speed and pole-changing motor 300 of pole-changing motor 300, the number of poles of pole-changing motor 300 is bigger, becomes

Motor 300 runs.Program for washing described here can be：The lotion state of washing machine S and the dewatering state of washing machine S.When
When controller 400 detects running status needed for washing machine S, the control pole-changing motor 300 of controller 400 is switched to corresponding equivalent
Number of poles runs.It is worth understanding, " running status needed for washing machine S " can be that pole-changing motor 300 is in number of poles high or low
The running status of washing machine S during series.For example, when controller 400 detects washing machine S and is in washing state, controller 400
Control pole-changing motor 300 switches to the one kind in various equivalent operation numbers of poles.It is changeable when the clothing in washing machine S is more
Pole-changing motor 300 is in the number of poles running status high of big torque, the slow-speed of revolution (for example, it may be the number of poles of pole-changing motor 300 is 16
Pole, the rotating speed of pole-changing motor 300 is 120rpm)；When controller 400 detects washing machine S is in dewatering state, controller 400
Control pole-changing motor 300 switches to the another kind in various equivalent operation numbers of poles, for example, can switch pole-changing motor 300 being in
Small torque, high-revolving low number of poles running status are (for example, it may be the number of poles of pole-changing motor 300 is 4 poles, the rotating speed of pole-changing motor 300
It is 800rpm).
The drive device of the washing machine S according to the utility model embodiment, by changing the equivalent of the pole-changing motor 300
Operation number of poles, so that pole-changing motor 300 keeps Effec-tive Function under washing machine S different working conditions, reduces washing machine S and washes
The energy consumption of clothing process.And controller 400 is provided with washing machine S, controller 400 can detect identification washing machine S
Working condition and the running status to pole-changing motor 300 adjusted accordingly so that washing machine S is more convenient and smart
Change, improve the overall performance of product.
According to one embodiment of the present utility model, the drive device of washing machine S also includes：For judging clothes weight
Weighing module (not shown) and the eccentric identification module (not shown) for recognizing clothing center of gravity.Weighing module and partially
Heart identification module is connected with the communication of controller 400, and controller 400 can be washed according to the position adjustment of clothes weight and clothing center of gravity
Clothing step.Thus, weighing detection can be carried out to the clothes weight in washing machine S by Weighing module, by eccentric module then
The position of centre of gravity of washing machine S undergarments can be detected, and the information transmission that Weighing module and eccentric module are detected is to control
Device 400, controller 400 receives detection information to select the different working modes of washing machine S, and adjusts pole-changing motor 300 and switch
To different working condition.
It is worth understanding, as shown in figure 8, " laundering step " described here can be, controller 400 is according to receiving
Information adjustment pole-changing motor 300 switch to correspondingly equivalent number of poles operation.When a laundering step is completed, controller 400
The working condition of pole-changing motor 300 is detected further according to the information for receiving, decides whether that switching pole-changing motor 300 is switched to
Different working condition, until laundry is completed.Thus, it is possible to make pole-changing motor 300 be kept under washing machine S different working conditions
Effec-tive Function, reduces the energy consumption of washing machine S laundry processes.
For example, when the clothes weight in Weighing module detects washing machine S is more than M, Weighing module is by the detection information
Pass to controller 400.Controller 400 receive can adjust after the detection information pole-changing motor 300 be in it is higher equivalent
Operation number of poles running status, now, pole-changing motor 300 is run with the working condition of big torque, the slow-speed of revolution；When Weighing module detection
To the clothing in washing machine S weight be less than M when, controller 400 can according to detection information adjust pole-changing motor 300 switch to
The relatively low running status of equivalent operation number of poles, now, pole-changing motor 300 is run with small torque, high-revolving working condition.From
And, the running status of washing machine S adjustment pole-changing motors 300 automatically and reasonably can be made, so that pole-changing motor 300 keeps efficiently fortune
OK, the energy consumption of washing machine S is reduced.
According to one embodiment of the present utility model, the drive device of washing machine S also includes：For selecting program for washing
Control button, control button is connected with the communication of controller 400, and controller 400 adjusts laundering step according to control button.Namely

The information switching pole-changing motor 300 transmitted according to control button runs to corresponding equivalent number of poles.Thus, user can be by choosing
The control button for selecting program for washing is selected the working condition of washing machine S, and program for washing control button receives selection information
And controller 400 is passed to, controller 400 carries out corresponding position switching by controlling switching mechanism 34, to adjust washing machine S
Different working modes.
Further, control button can be push type mechanical key or touch key-press.That is, control button both may be used
Think push type mechanical key, or touch key-press.Can be carried out accordingly according to the holistic cost of washing machine S and aesthetics
Selection.
In some embodiments of the present utility model, pole-changing motor 300 can be winding pole-changing motor 300, mechanical switch
Pole-changing motor 300 or the formula pole-changing motor 300 that magnetizes.In other words, the pole-changing motor 300 of washing machine S can be using winding pole-changing electricity
Pole, it would however also be possible to employ mechanical switch pole-changing electrode, certainly can also be using magnetize formula pole-changing motor 300 or other pole-changing motors
300.In actual selection application, can be selected according to the design cost of washing machine S and overall performance.
