Below, roller washing machine operation principle of the present invention is described:
At first, roller washing machine of the present invention allows the front side of cylinder 3 and wash bucket 2 and ground form 10～30 ° inclination angle, can throw in or take out clothing easily.
In the conventional art, the user drops into clothing or need take to squat down or the posture of bending over very inconvenience when cylinder 3 takes out clothing in cylinder 3.Different therewith, by wash bucket 2 and cylinder 3 are set obliquely, can allow the user carry out the input or the taking-up of clothing at an easy rate among the present invention.
Meanwhile, roller washing machine of the present invention has improved scourability by in cylinder 3 inside impeller being set.
Be in the conventional art,, allow lifting member 3a promote and leave clothing that wash, there is certain limit in the raising of its scourability only by the rotation of cylinder.But among the present invention, when being obliquely installed the wash bucket 2 of roller washing machine and cylinder 3, in cylinder 3 inside impeller is set, lifting member 3a effect when having improved washing and the percussion between impeller 7 and the clothing, and utilize the heeling condition of cylinder 3 and the structure of impeller 7, allow clothing flow forwards, backwards better, can significantly improve scourability.
In more detail, wash bucket 2 and cylinder 3 are tilted setting, impeller axle 8 runs through hollow shape drum shaft 6, be connected under the state of pulley 15 of motor rear side, by restraint device 11 power supplys that are fixed on wash bucket 2 rear wall parts etc. are controlled, utilize the electromagnetic valve 11a and the effect of compressing spring 11c of restraint device 11, allow piston 11b maintenance be inserted in the state in the disc pulley 15 holddown groove 150a or to make it and extract out, retrain or release pulley 15 from holddown groove 150a.This means, can promptly retrain or discharge pulley 15.
By the way, allow impeller 7 be in stationary state or rotatable state, can allow cylinder 3 interior clothings have multiple flow regime, improve scourability.
When dewatering, also can allow piston 11 be inserted among the holddown groove 150a of pulley 15, make impeller 7 be in stationary state, or allow piston 11 extract out from the holddown groove 150a of pulley 15, make impeller 7 be in rotatable state.
If when dehydration, electromagnetic valve 11a is switched on, piston 11b is extracted out from the holddown groove 150a of pulley 15, though then impeller 7 might rotate along with cylinder 3 carry out high speed together, but the strong rotation under the direct driving that to be not cylinder such of rotation at this moment.That is, the rotation of impeller 7 and motor and asynchronous, but in the cylinder that is rotated at a high speed under the drive of clothing, be rotated with the speed that approaches cylinder 3.
Along with improving scourability, roller washing machine of the present invention is provided with autobalance 9 in the inboard, front and back of cylinder 3, can more effectively reduce the system vibration under the effect of eccentric weight power.Fluid is being filled in the inboard of autobalance 9, allows cylinder keep balance, and this has any different with the balance weight that is installed in wash bucket 2.
Particularly, roller washing machine of the present invention, because wash bucket 2 and cylinder are in the state that is provided with of inclination, the vibration of its rear side is bigger than traditional roller washing machine.But, can reduce the vibration of rear side effectively by autobalance also being installed in the inboard at cylinder 3 rears.
As mentioned above, when with heeling condition wash bucket 2 being set, the cylinder 3 of wash bucket 2 inboards also has heeling condition, can suitably pour into washings on a small quantity to cylinder 3 inside, washs.
Such as, the cylinder 3 of roller washing machine of the present invention is provided with being tilted, and the part of clothing is collected at the bottom side of cylinder 3, when therefore pouring water, can only pour into the amount of soaking the rear side clothing.
In addition, in the roller washing machine of the present invention, allow the engaging piece 15c of pulley 15 be positioned at drum shaft 6 inside during fabricated sheave 15, can reduce the total length of roller washing machine.
That is, under heeling condition, if the engaging piece 15c of pulley can not be positioned at the inside of drum shaft 6, then total length is elongated, and allows the capacity of roller washing machine descend.But, in the roller washing machine of the present invention, allow the engaging piece 15c of pulley 15 be positioned at drum shaft 6 inside during fabricated sheave 15, can reduce the total length of roller washing machine, improve washing capacity.
Below, pulley control procedure and principle when roller washing machine of the present invention is carried out laundry operation describe:
At first, with reference to Fig. 3 a, the process of carrying out laundry operation with the fixing state rotary drum 3 of impeller 7 is described:
Shown in Fig. 3 a, piston 11b advances, and is positioned at the holddown groove 150a of pulley 15, and pulley 15 can't be rotated, and impeller is fixed in the cylinder 3.Under this state, beginning is during washing stroke, rotor 4 and stator 5 between electromagnetic action under, be rotated.The cylinder 3 that is connected on the rotor 4 in the mode of being coupling is rotated thereupon.
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 when landing on impeller 7 and washing wing 7a, is moved to the place ahead.
Because the washing wing 7a and the impeller central part of roller washing machine of the present invention have outstanding structure, 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 washing 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 is identical with foregoing, receives the signal of microprocessor (figure slightly), stirs 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 washing 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.
