In addition, in order to realize above-mentioned multiple drum driven action, above-mentioned motor 140 is the direct type motor preferably.That is, the stator that preferably constitutes motor is fixed in the rear of wash bucket 120, and the rotor of motor is rotated, and directly drives the form of above-mentioned cylinder 130.This be because, direction of rotation, moment of torsion etc. by the control motor can farthest prevent temporal delay or backlash (backlash), thus index drum drive actions at once.
In addition, send in the form of rotating shaft by pinion (pulley) etc. at revolving force motor, can adopt the drum driven action of the form that allows temporal delay or backlash, for example, can adopt upset to drive or the driving etc. of spinning, therefore, do not advise adopting in order to realize multiple drum driven action.The type of drive form of motor and cylinder belongs to common practise for the technical staff of relevant industries, will save detailed explanation at this.
Fig. 2 (a) is the schematic diagram that illustrates scroll actions (roiling motion), above-mentioned scroll actions is to be controlled as, above-mentioned motor 140 makes cylinder 130 be rotated to a direction, the minimum point of cylinder is set at 0 degree, and will locate reference starting point as cylinder rotation, the washings of above-mentioned cylinder inner peripheral surface is about the action that position below 90 degree drops to the minimum point of cylinder from the direction of rotation of cylinder.
Promptly, when motor 140 makes cylinder be rotated to be about 40RPM, after the washings that is positioned at the minimum point of above-mentioned cylinder 130 both rises to take the altitude along the direction of rotation of cylinder 130, to be about position below 90 degree to direction of rotation from the minimum point of above-mentioned cylinder, as flowing to the minimum point of above-mentioned cylinder as rolling, when visually looking, will constitute at cylinder when clockwise direction rotates, washings is from the form of the third quadrant face progressive rolling movement of cylinder.
Washings is by above-mentioned scroll actions, and by and the friction of washings, the friction between the washings, and carry out washing operation with the friction of cylinder inner peripheral surface, and, by above-mentioned action the upset of washings will take place fully, thereby can obtain soft effect of washing washings by rubbing with the hands.
Wherein, cylinder RPM by with the relation decision of the radius of cylinder, promptly, when the RPM of cylinder becomes big, to produce centrifugal force in the washings in the cylinder, because the size of above-mentioned centrifugal force and gravity there are differences, flowing of the washings of cylinder inside will be different, certainly, need consider the revolving force of cylinder and the frictional force between cylinder and the washings simultaneously.
Therefore, in scroll actions, the RPM of decision cylinder is so that the centrifugal force and the frictional force that produce are less than gravity (1G).
Fig. 2 (b) is the schematic diagram that illustrates rotary movement (tumbling motion).
Above-mentioned rotary movement is to be controlled as, and above-mentioned motor 140 makes cylinder 130 be rotated to a direction, and the washings of above-mentioned cylinder inner peripheral surface is about 90 degree drop to the minimum point of cylinder to 110 degree positions action from the direction of rotation of cylinder.In above-mentioned rotary movement, only need index drum to be rotated to a direction and can produce mechanicals efforts with suitable RPM, it is the general drum driven action of using when washing and cleaning operation.
Promptly, before motor 140 drives, the washings of throwing in the cylinder 130 will be positioned at the minimum point of above-mentioned cylinder 130, when above-mentioned motor 140 when above-mentioned cylinder 130 provides moment of torsion, above-mentioned cylinder 130 will be rotated, the lifting device 135 that is arranged at the inner peripheral surface of above-mentioned cylinder moves to both take the altitudes with washings from the minimum point in the cylinder, when above-mentioned motor 140 makes above-mentioned cylinder 130 be rotated to be about the 46RPM degree, washings will be about 90 degree to the position of 110 degree to direction of rotation from the minimum point of above-mentioned cylinder and drop to the minimum point direction of cylinder.
In rotary movement, the RPM of decision cylinder so that the centrifugal force that produces during greater than scroll actions centrifugal force and less than gravity.
When visually looking, rotary movement will constitute at cylinder when clockwise direction rotates, after washings moves to the part of third quadrant face to the second quadrant face from the minimum point of cylinder, break away from and drop to the form of the minimum point of cylinder from the inner peripheral surface of cylinder.
Thus, in above-mentioned rotary movement, to make washings by carrying out washing operation with the friction of washings and the impulsive force that causes that drops, and the mechanicals efforts with greater than above-mentioned scroll actions the time carried out washing and cleaning operation, and, owing to be to break away from the inside of cylinder and the action of dropping to a certain degree, the effect that can obtain making the washings of mutual winding to separate and disperse washings.
Fig. 2 (c) is the schematic diagram that illustrates stepwise operation (step motion), above-mentioned stepwise operation is to be controlled as, above-mentioned motor 140 makes cylinder 130 be rotated to a direction, and the washings of above-mentioned cylinder inner peripheral surface peak (being about 180 degree positions) on the direction of rotation of cylinder drops to the action of the minimum point of cylinder.
When above-mentioned motor 140 made above-mentioned cylinder 130 be rotated more than the 60RPM to be about, washings can not have being rotated of dropping under action of centrifugal force.Above-mentioned stepwise operation be make above-mentioned cylinder with washings after preventing under the action of centrifugal force to be rotated from the speed that the cylinder inner peripheral surface drops, by the above-mentioned cylinder of brake hard, make the action of the impulsive force maximization that washings is subjected to.
In above-mentioned stepwise operation, be controlled as, above-mentioned motor 140 make above-mentioned cylinder with washings after the speed (being about more than the 60RPM) that prevents under the action of centrifugal force to drop from the inner peripheral surface of cylinder is rotated, be positioned at washings under near the situation the peak (direction of rotation 180 degree) of cylinder, will be to above-mentioned cylinder 130 supply moments of torsion.
Thus, after the direction of rotation of washings from the minimum point of above-mentioned cylinder 130 along cylinder promotes, the moment in that the torsional interaction bottom roll of motor 140 is stopped, will drop to minimum point from the peak of cylinder 130.Therefore, above-mentioned stepwise operation is that the impulsive force that causes in the process that drops with maximum drop of the washings by cylinder inside is carried out the action of washing operation, will be greater than aforesaid scroll actions or rotary movement by the mechanicals efforts that above-mentioned stepwise operation produces.
When visually looking, stepwise operation will constitute at cylinder when clockwise direction rotates, through third quadrant face to the second quadrant face and after moving to the peak of cylinder, the inner peripheral surface from cylinder breaks away from suddenly from the minimum point of cylinder, and drops to the form of the minimum point of cylinder.Thus, in stepwise operation, the distance that drops in the inside of cylinder under the less situation of washing bag amount, can more effectively provide mechanicals efforts with maximum.
In addition, for the braking of above-mentioned cylinder, above-mentioned motor 140 is preferably by plugging, and above-mentioned plugging is that the opposite direction of the direction in the motor rotation produces the mode of revolving force with braking motor.For produce with motor rotation in side's revolving force in the opposite direction, the phase place (phase) of the electric current of supplying with in the motor is reversed, above-mentioned plugging makes the brake hard of motor become possibility, therefore, above-mentioned plugging will be the mode of braking that is fit to the most for the above-mentioned stepwise operation that applies thump to washings.
Subsequently, above-mentioned motor 140 applies moment of torsion to above-mentioned cylinder 130 again, make the washings of the minimum point of cylinder rise to peak, promptly, applying moment of torsion after the clockwise direction rotation, apply moment of torsion moment is rotated promptly to stop to counter clockwise direction, will rotate to clockwise direction again with after-applied moment of torsion, thereby realize above-mentioned stepwise operation.
Consequently, above-mentioned stepwise operation is when cylinder is rotated, and the washings and the washings that flow into through hole 131 is rubbed, and carry out washing operation, when washings is positioned at the peak of cylinder, it is dropped, and carry out the action of washing operation by impulsive force.
Fig. 2 (d) is the schematic diagram that illustrates wobbling action (swing motion), above-mentioned wobbling action is to be controlled as, above-mentioned motor 140 makes cylinder 130 be rotated to two directions, and makes washings be about the action of dropping in the position below 90 degree from the direction of rotation of cylinder.
Promptly, when above-mentioned motor 140 makes above-mentioned cylinder 130 when counter clockwise direction is rotated to be about 40RPM, the washings that is positioned at the minimum point of above-mentioned cylinder 130 will rise to both take the altitudes to counter clockwise direction, at this moment, washings arrive be about the positions of 90 degree from the counter clockwise direction of cylinder before, above-mentioned motor makes cylinder stop to be rotated, thereby washings is moved to the minimum point direction of cylinder from the position that the counter clockwise direction of cylinder is about below 90 degree.
Subsequently, above-mentioned motor 140 makes above-mentioned cylinder 130 be rotated to be about 40RPM to clockwise direction, and make the washings in dropping rise to both take the altitudes to clockwise direction along the direction of rotation of cylinder, at this moment, washings arrive be about the positions of 90 degree from the clockwise direction of cylinder before, above-mentioned motor 140 makes cylinder stop to be rotated, thereby washings is moved to the minimum point direction of cylinder from the position that the clockwise direction of cylinder is about below 90 degree.
Promptly, wobbling action is the direction rotation of cylinder and stops and action that contrary direction rotation and stopping to be carried out repeatedly, when visually looking, it is to carry out four-quadrant face that washings is thus lifted to cylinder repeatedly to a first quartile face part and soft dropping, and is thus lifted to third quadrant face to the second quadrant face part of cylinder and the form of soft action of dropping.
At this, will utilize dynamic brake as the braking of above-mentioned motor 140, make the load minimizes that produces in the motor 140 thus, make the minimized while of mechanical friction of motor 140, can regulate the impact that applies on the washings.
Above-mentioned dynamic brake is that motor will play the mode of braking of the effect of generator under the effect of rotatory inertia when utilizing the electric current that inserts in the motor to be closed (OFF).When the electric current that inserts in the motor is closed (OFF), flow on the coil of electric current sense of current will sense of current be opposite before with power-off (OFF), thereby will produce active force (Fu Laiming right-hand rule), and braking motor to the direction that hinders the motor rotation.Above-mentioned dynamic brake is different with above-mentioned plugging, and it does not make motor by brake hard, but the direction of rotation of soft conversion cylinder.
Therefore, when visually looking, above-mentioned wobbling action will constitute washings striding across the third quadrant face and the four-quadrant face of cylinder, and the form that flows with 8 font attitudes of accumbency.
Fig. 2 (e) illustrates the schematic diagram of cleaning action (scrub motion), above-mentioned scouring action is to be controlled as, above-mentioned motor 140 makes cylinder 130 be rotated with two directions, and makes washings be about the action of dropping in the position more than 90 degree from the direction of rotation of cylinder.
Promptly, when above-mentioned motor 140 makes above-mentioned cylinder 130 when counter clockwise direction is rotated to be about 60RPM, the washings that is positioned at the minimum point of above-mentioned cylinder 130 will rise to both take the altitudes to counter clockwise direction, at this moment, after washings is through the position that is about 90 degree on the counter clockwise direction of cylinder, above-mentioned motor will provide contrary moment of torsion to cylinder, thereby make above-mentioned cylinder temporarily stop to be rotated, at this moment, the washings of the inner peripheral surface of cylinder will sharply drop.
Subsequently, above-mentioned motor 140 makes above-mentioned cylinder 130 be rotated to be about 60RPM to clockwise direction, and make the washings that drops rise to both take the altitudes to clockwise direction, at this moment, behind the position of washings through 90 degree on the clockwise direction of cylinder, above-mentioned motor 140 will provide contrary moment of torsion to cylinder, thereby make above-mentioned cylinder temporarily stop to be rotated, at this moment, the washings of the inner peripheral surface of cylinder position more than 90 degree from the clockwise direction of cylinder drops to the minimum point of cylinder.
Thus, in above-mentioned scouring action, sharply drop and washings is carried out washing operation from both take the altitudes by washings.In addition, in order to brake above-mentioned cylinder, above-mentioned motor 140 is preferably by plugging.
Because the direction of rotation of cylinder is sharply changed, the inner peripheral surface of the disengaging cylinder that washings will can be not bigger, thus can obtain the very powerful effect of washing by rubbing with the hands.Above-mentioned scouring action is to carry out repeatedly sharply dropping through four-quadrant face and the washings that moves to a first quartile face part, again through the third quadrant face and move to the form of the action of dropping after the second quadrant face part.Therefore, when visually looking, above-mentioned scouring action will constitute the form of the action that the washings that is raised descends repeatedly along the inner peripheral surface of cylinder.
Fig. 2 (f) is the schematic diagram that illustrates filter action (filtration), above-mentioned filter action is, above-mentioned motor 140 is rotated cylinder 130, and makes washings prevent to drop from the inner peripheral surface of cylinder under action of centrifugal force, and the while is to the action of the internal spray washings of above-mentioned cylinder.
Promptly, in above-mentioned filter action, after being unfolded, washings is close in the process that the inner peripheral surface of cylinder is rotated, will be to the internal spray washings of cylinder, and washings are under action of centrifugal force, to be discharged to wash bucket 120 via the through hole 131 of washings, cylinder, thus, in above-mentioned filter action, when the surface area that makes washings is widened, because washings can connect washings, can obtain making washings to supply to the effect of washings uniformly.
In above-mentioned filter action, will realize in the following way to the mode of roller spray washings, that is, utilize circulation stream (not shown) and take out pump (not shown) washings that store in the wash bucket are circulated and to spray.
In addition, in above-mentioned filter action, can be under the situation that washings do not spray, the inner peripheral surface that makes washings be close to cylinder is rotated, this will produce the dispersion of washing bag, is suitable for for the dispersion that produces the washing bag in washing process thereby soak the back at the washing bag.
And, in above-mentioned filter action, the washings that store in the wash bucket are not circulated, but carry out from the mode of the clean washings of the water-supply source supply of outside with injection.For with wash bucket in the situation of the washings circulation that stores distinguish, at this it is defined as jet cleaning action (Spray Rinse motion), to utilize clean washings in above-mentioned jet cleaning action, therefore, it is the action that is suitable for the stroke of needs cleaning.
Fig. 2 (g) is the schematic diagram that illustrates extrusion action (squeeze motion), above-mentioned extrusion action is, above-mentioned motor 140 is rotated cylinder 130, and make washings under action of centrifugal force, prevent to drop from the inner peripheral surface of cylinder, reduce the rotary speed of cylinder 130 subsequently, and carry out the action that washings separates from the inner peripheral surface of cylinder repeatedly, and in the rotary course of above-mentioned cylinder to the action of the internal spray washings of cylinder.
Promptly, the difference of above-mentioned filter action and above-mentioned extrusion action is, in above-mentioned filter action, to proceed rotation with the speed that washings does not drop from the inner peripheral surface of cylinder, but in above-mentioned extrusion action, to change the rotary speed of above-mentioned cylinder, and carry out the action that washings is close to and is separated from the inner peripheral surface of cylinder 130 repeatedly.
Though the not shown process that goes out in above-mentioned filter action and extrusion action to the internal spray washings of above-mentioned cylinder 130 among Fig. 2, but it can and take out pump and realize by the circulation stream, it can be set to, the above-mentioned pump of taking out is communicated with and the washings that pressurize with the bottom surface of wash bucket 120, one side of above-mentioned circulation stream is connected with the above-mentioned pump of taking out, opposite side from the top of above-mentioned cylinder to the internal spray washings of cylinder.
Just, above-mentioned circulation stream and necessary structure when taking out pump and being the washings that in spraying wash bucket, store, it is not the situation that is intended to get rid of by the internal spray washings of the above-mentioned cylinder of injection feedwater flow road direction that is connected with the water-supply source of hull outside.
That is, when a side of above-mentioned injection feedwater stream is connected with water-supply source, opposite side is connected with above-mentioned wash bucket, and be provided with can be when the nozzle of the internal spray washings of above-mentioned cylinder, can filter action with extrude move in to the internal spray washings of cylinder.
Fig. 3 is the more detailed schematic diagram that illustrates above-mentioned stepwise operation.When motor 140 when cylinder 130 applies moment of torsion with certain orientation, cylinder 130 will be rotated to moving direction, and washings will be close to the inner peripheral surface of cylinder 130 and promote, at this moment, for the inner peripheral surface that makes washings be close to cylinder promotes, cylinder preferably is rotated to be about more than the 60RPM.Wherein, the rotary speed of cylinder by with the relation decision of the internal diameter of cylinder, it is decided to be centrifugal force will be greater than the rotary speed of gravity.
In the positions of washings 90 degree on the direction of rotation of the cylinder 130 of associating and reach in the cylinder before the peak, temporarily stop the rotation in order to make above-mentioned cylinder, motor 140 will be by plugging.Because the position of the washings in the plugging time point of motor 140 and the cylinder 130 has close association, therefore, preferably is provided with the device that can judge or dope the position of washings.As the one example, can be the checkout gear of the Hall element (Hall effect sensor) that is provided with the anglec of rotation that to judge rotor.
Control part also can be judged direction of rotation by above-mentioned Hall element except the anglec of rotation of rotor.Xiang Guan content belongs to common practise for the technical staff of relevant industries therewith, will save detailed explanation at this.
Control part can be judged the anglec of rotation of cylinder by above-mentioned detection device, and before cylinder arrives 180 degree the above-mentioned motor of control 140 by plugging.Wherein, plugging refers to, and inserts anti-phase electric current for cylinder is rotated round about.For example, in motor, insert electric current and make it after the clockwise direction rotation, insert electric current suddenly and make it to rotation counterclockwise.
Thus, cylinder in the clockwise direction rotation will stop to be rotated moment, and the angle of this moment reaches 180 degree in fact, thereby makes washings drop to the minimum point of cylinder inside from the peak of cylinder inside, subsequently, in order to make cylinder continue to continue to insert electric current to the clockwise direction rotation.
Illustrate cylinder among Fig. 3 to right handed situation, but also can carry out stepwise operation in the rotation in the counterclockwise direction, just, owing in above-mentioned stepwise operation, on motor 140, will produce high capacity, therefore, preferably reduction is clean moves rate and carries out above-mentioned stepwise operation.
Clean moving rate refers to the ratio for the motor-driven time of the summation of the driving time of motor 140 and dwell time, and moving only rate is driving of 1 no dwell time of expression.Under the situation of above-mentioned stepwise operation, consider the load of accepting in the motor, preferably control to be about 70% clean moving rate.As the one example, can be to stop 4 second time after driving 10 second time.
Fig. 4 is the more detailed schematic diagram of cleaning action that illustrates.When motor 140 when cylinder 130 applies moment of torsion, washings in the cylinder will be rotated to clockwise direction, for the inner peripheral surface that makes washings be close to cylinder is rotated, preferably controls above-mentioned motor 140 and above-mentioned cylinder 130 is had be about the above rotation number of 60RPM.Subsequently, when washings passes through the position of 90 degree on the direction of rotation of cylinder, because motor 140 will be by plugging, the washings of being close to the inner peripheral surface of cylinder will drop to the minimum point of cylinder.
When washings drops to minimum point, above-mentioned motor 140 will provide and make cylinder to the moment of torsion that counterclockwise rotates, thus, the washings that drops will be close to the inner peripheral surface of cylinder and be rotated to counter clockwise direction, when washings be in minimum point from cylinder on counter clockwise direction 90 degree positions and the peak of cylinder between the time, above-mentioned motor will be by plugging, and the washings of being close to the inner peripheral surface of cylinder will drop to the minimum point of cylinder.
Identical with above-mentioned stepwise operation, because above-mentioned scouring action also will produce high capacity on motor 140, preferably reduce clean moving rate and carry out above-mentioned scouring action.As the one example, can be to carry out repeatedly carrying out the operation that stops 4 second time after scouring is moved, thereby control with 70% clean moving rate with 10 second time.
In addition, though not shown, in wobbling action, the mode of braking of the motor in the above-mentioned scouring action is changed to dynamic brake, and the time point of dynamic brake changed to get final product when washings arrives on the direction of rotation of cylinder 90 degree positions, so will save detailed explanation.
