Here, cylinder 3 receives the signal of microprocessor (figure slightly), carry out left rotation and right rotation by some cycles, and impeller 7 keeps halted state.
Thereupon, the clothing in the cylinder 3 is promoted and leaves by a plurality of lifting member 3a, washs.Because cylinder 3 is in heeling condition, the part of clothing is bumped on impeller 7 and impeller wing 7a when landing, is moved to the place ahead.
Because the impeller wing 7a and the impeller central part of roller washing machine of the present invention have the structure of protrusion, therefore be raised the clothing that leaves after part 3a promotes, carry out flowing before and after more with originally comparing.That is, the inclined-plane of impeller wing 7a and the surface curvature of impeller 7 and inclination angle etc. is set can cause the change in location of clothing.
Because cylinder 3 is with the heeling condition rotation, and impeller is in stationary state, therefore under the influence of the speed difference between cylinder 3 and the impeller 7, the clothing that forms on the multiple direction flows and the washing current.
The washing current are distributed to other positions of cylinder to the clothing that accumulates in cylinder 3 rear sides, make the distribution of clothing more even.
That is, when washing, the current that cause by the collision between washings and the impeller 7, and, can improve the clean result of washings greatly by the impulsive force that the collision between clothing and the impeller 7 causes, and cleaning performance.
Below, with reference to Fig. 3 b, to being disengaged when the constraint of pulley 15, the washing process when impeller 7 is in rotatable state describes.
Shown in Fig. 3 b, connect power supply to electromagnetic valve 11a, attract piston 11b, move backward when allowing piston 11b that compression spring 11c is compressed, break away from from the holddown groove 150a of pulley 15, make pulley 15 be in rotatable state, and allow impeller 7 be in rotatable state.
At this moment, if the beginning washing stroke, then rotor 4 and stator 5 between electromagnetic action under, be rotated, the cylinder 3 that is coupling with rotor 4 is rotated thereupon.
Here, cylinder 3, identical with foregoing, receive the signal of microprocessor (figure is slightly), stir rotation about being undertaken by certain cycle, and impeller 7 is when cylinder 3 rotations under the flowing water flow effect, by left rotation and right rotation.
A plurality of lifting member 3a of cylinder 2 inside promote and leave clothing, wash.Because cylinder 3 is in heeling condition, so the part of clothing is when being left, and bumps with the impeller 7 of rotation.
Clothing with impeller 7 collisions is moved to the place ahead.
That is, identical with the explanation of front, because roller washing machine of the present invention, the surface that its impeller wing 7a has inclined-plane and an impeller 7 has curvature and reason such as inclination angle is set, and can cause the bigger change in location of clothing.
Simultaneously, though impeller 7 is in rotation status, its rotation is not to force the constant speed rotation, and there is some difference with the rotary speed of cylinder 3.The clothing that therefore can form on the multiple direction flows and the washing current.
That is, though compare with the state that impeller 7 is fixed, speed difference is less, still has between cylinder 3 and the impeller 7 to be beneficial to the speed difference that washings flows.This helps improving clean result and cleaning performance.
Can under the state of fixing impeller 7, utilize bigger speed difference to wash such as, roller washing machine of the present invention, also can be under the situation of free rotation state, utilize less speed difference to wash at impeller 7.
In addition, during washing, under the state of fixing or release impeller 7, make the short period of cylinder 3, carry out positive and negative rotation, wash can allow clothing do not left.
Roller washing machine of the present invention is dewatering and when dry, can be by the control restraint device, and fixedly impeller 7 or discharge dewaters under impeller 7 states and drying.
The present invention is not subject to embodiment, under the prerequisite that does not exceed the technology of the present invention thought range, can much change and revise.
Such as, also can be on the inner peripheral surface of cylinder 3, built-in rotatable small-sized impeller.
