Background
In the process of dehydrating clothes, a washing machine is taken as an example for explanation, and the clothes treatment equipment usually shakes and looses the clothes by shaking and looses the rotation speed to rotate positively and negatively, then increases the rotation speed to a distribution rotation speed, and finally enters a pulse rotation speed and a set rotation speed for spin-drying.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. Those skilled in the art can adapt it as desired to suit a particular application. For example, although in the step 300 in the specification, there is a step of "stably operating at the rotation speed of the pre-determined rotation speed Vb1 for a time t 1" after "until the pre-determined rotation speed Vb1 is reached", this step is provided for ensuring the stable operation of the washing machine again, and even without this step, the control method of the present invention can already determine that it can stably operate, so this one double-insurance step is obviously omitted, as long as it is still possible to achieve the reduction of the risk of the laundry treatment apparatus colliding with the tub.
It should be noted that, in the present application, the distribution eccentric values M1, M2, M3 and the like are differences between the preset rotation speed and the actual rotation speed, and the more uneven the distribution of the laundry in the laundry treatment apparatus is, the larger the values of the distribution eccentric values M1, M2, M3 and the like are.
Note that, in the present application, the shake-out rotation speed Va1, the pre-determination rotation speed Vb1, the distribution rotation speed Vc1, the pulse rotation speed Vd, the deceleration rotation speed Ve, the pre-determination acceleration a, the pre-determination acceleration b, the acceleration c, the first preset value Mf1, the second preset value Mf2, and the third preset value Mf3 are all system preset values, and the Mfa, mfb, mfc, mfd, mfe, mff, the accelerations c1, c2, c3, c4, c5, c6, the pulse rotation speeds Vd1, vd2, vd3, vd4, vd5, and Vd6 are also all system preset values.
The set rotation speed Vf mentioned in the present application is a rotation speed when the laundry treatment apparatus maintains high-speed dehydration, and the time Δtb for continuous operation and the set rotation speed Vf are both system set values. t1 and t2 are preset values of the system, and P, N are natural numbers greater than or equal to 1.
Referring to fig. 1 to 3, a dehydration control method of a laundry treating apparatus of the present invention will be described in detail.
As shown in fig. 1 and 3, in order to solve the problem that the existing dehydration control method is unreasonable to control during the shaking phase to the distribution phase, and is easy to cause unbalance of the laundry treatment apparatus, the dehydration control method of the laundry treatment apparatus of the present invention comprises the following steps:
s100, controlling the clothes treatment equipment to shake and scatter clothes in a positive and negative rotation mode at a shake-out rotation speed Va 1;
before the clothes are dried by the washing machine, the clothes are firstly subjected to shaking-off so as to be uniformly distributed in an inner barrel of the washing machine, so that the clothes are prevented from being eccentric greatly, and preparation is made for subsequent drying.
S200, controlling the clothes treatment equipment to increase from the shaking rotation speed Va1 to the preset rotation speed Vb1 at the preset acceleration a, and monitoring the distribution eccentric value M1 of clothes in real time;
s300, in the process of rising from the shake-off rotation speed Va1 to the pre-judging rotation speed Vb1, if M1 is always smaller than a first preset value Mf1, the shake-off rotation speed Va1 is allowed to rise to the pre-judging rotation speed Vb1 until the pre-judging rotation speed Vb1 is reached, and the operation is carried out for t1 time at the rotation speed of the pre-judging rotation speed Vb1;
s310, in the process of increasing from the shake-out rotation speed Va1 to the pre-determination rotation speed Vb1, if M1 is equal to or greater than the first preset value Mf1, the shake-out rotation speed Va1 is not allowed to increase to the pre-determination rotation speed Vb1, and the process returns to step S100.
The pre-judging rotating speed Vb1 with the pre-judging eccentricity is directly increased between the shaking rotating speed Va1 and the distributing rotating speed Vc1, so that the risk that the washing machine collides due to overlarge distributing eccentricity caused by directly increasing the pre-judging rotating speed to the distributing rotating speed Vc1 is avoided. When the distribution eccentric value M1 is always smaller than the first preset value Mf1, it is indicated that the distribution eccentric value M1 is within the allowed range at this time, no collision occurs to the washing machine at this time, and Va1 can be controlled to be increased until reaching the preset rotation speed Vb1, and in order to ensure the stability of the operation of the washing machine again, after reaching the preset rotation speed Vb1, the operation is continued for t1 time at the rotation speed of the preset rotation speed Vb1, and the curve of successful distribution is shown in fig. 3. When the distribution eccentric value M1 is equal to or greater than the first preset value Mf1, it is indicated that the distribution eccentric value M1 exceeds the allowable maximum range at this time, and if the distribution rotating speed Vc1 is increased, the risk of striking the washing machine is very likely to occur, the shaking rotation speed Va1 is not allowed to increase to the preset rotating speed Vb1, and the process returns to step S100, and the shaking distribution is performed again (the rotation speed change at the time of failure is not shown in fig. 3, and the following description).
S400, controlling the clothes treatment equipment to rise from the preset rotating speed Vb1 to the distribution rotating speed Vc1 at the preset acceleration b, and monitoring the distribution eccentric value M2 of clothes in real time;
s500, in the process of rising from the preset rotating speed Vb1 to the distributed rotating speed Vc1, if M2 is always smaller than a second preset value Mf2, the preset rotating speed Vb1 is allowed to rise to the distributed rotating speed Vc1 until reaching the distributed rotating speed Vc1, and the operation is performed stably for t2 time at the rotating speed of the distributed rotating speed Vc1;
s510, if M2 is equal to or greater than the second preset value Mf2 during the process of increasing from the pre-determination rotation speed Vb1 to the distribution rotation speed Vc1, the pre-determination rotation speed Vb1 is not allowed to increase to the distribution rotation speed Vc1, and the process returns to step S100.
When the running rotating speed of the pulsator washing machine reaches the preset rotating speed Vb1, starting to prepare to rise from the preset rotating speed Vb1 to the distribution rotating speed Vc1 at the preset acceleration b, and monitoring the distribution eccentric value M2 of clothes in real time; at this time, the first preset values Mf1 to Mf2 are modified and M2 is compared with Mf2, and similarly to the above steps S200, S300 and S310, when M2 is always smaller than the second preset value Mf2, the operation pre-determination rotation speed Vb1 is increased to the distribution rotation speed Vc1, and in order to ensure the stability of the washing machine, the operation is further stabilized with Vc1 for t2 time. When M2 is greater than the second preset value Mf2, it is indicated that the collision of the washing machine may occur by continuing the rising again, the distribution fails, the rising of the pre-determination rotation speed Vb1 is stopped, and the step S100 is returned to again perform the shaking distribution.
S600, controlling the clothes treatment equipment to rise from the distribution rotating speed Vc1 to the pulse rotating speed Vd, and then reducing from the pulse rotating speed Vd to the distribution rotating speed Vc1 until the dehydration is finished.
As shown in fig. 2 and 3, the step S600 further includes:
s610, monitoring a distribution eccentric value M3 of clothes in real time;
s620, when M3 is always smaller than a third preset value Mf3, selecting the matched acceleration c and the pulse rotating speed Vd to be achieved according to the actual value of the distributed eccentric value M3;
s630, controlling the clothes treatment equipment to rise from the distribution rotating speed Vc1 to the pulse rotating speed Vd by the acceleration c, and then reducing from the pulse rotating speed Vd to the distribution rotating speed Vc1 until the dehydration is finished.
After the clothes treatment device is stabilized at the distribution rotating speed Vc1, the clothes treatment device starts to be ready to rise to the pulse rotating speed Vd, before the clothes treatment device needs to detect the distribution eccentric value M3 and compare the distribution eccentric value with a third preset value Mf3, different acceleration c and the pulse rotating speed Vd to be achieved are selected according to the actual value of M3, and it is noted that the clothes treatment device adopts a mode of detecting M3 in real time in the invention, so that after each pulse is completed, the distribution eccentric value M3 is latest, namely the whole distribution eccentric condition after the clothes are thrown out of partial water is updated in real time, the rising speed of the next pulse rotating speed is updated in real time and is accurate, and the collision probability of the washing machine is further reduced.
With continued reference to fig. 2 and 3, the selection of the matched acceleration c, rise time Δta, and pulse rotation speed Vd to be achieved "according to the actual value of the distributed eccentricity M3" in step S620 further includes:
s621, when Mfa is less than M3 and less than or equal to Mfb, the acceleration c is c1, and the pulse rotating speed Vd is Vd1;
s622, when Mfb is less than M3 and less than or equal to Mfc, the acceleration c is c2, and the pulse rotating speed Vd is Vd2;
s623, when Mfc is less than M3 and less than or equal to Mfd, the acceleration c is c3, and the pulse rotation speed Vd is Vd3;
s624, when M3 is smaller than Mfd and smaller than Mfe, the acceleration c is c4, and the pulse rotating speed Vd is Vd4;
s625, when Mfe is less than M3 and less than or equal to Mff, the acceleration c is c5, and the pulse rotating speed Vd is Vd5;
s626, when Mff is smaller than M3, the acceleration c is c6, and the pulse rotation speed Vd is Vd6;
s627, returning to the step S100 again when M3 is larger than or equal to a third preset value Mf3, recording one failure time, stopping dehydration when the accumulated failure time reaches P times, and prompting dehydration failure information; wherein P is a natural number of 1 or more.
After detecting the actual values of the distributed eccentric value M3, the washing machine can select the proper acceleration c and the pulse rotation speed Vd according to the six groups of segments, only the value fluctuation of the two groups of the selected values of c1, vd1, c2 and Vd2 is shown in fig. 3 by way of example, other values can be selected, in addition, the invention only divides the value range of M3 into six groups by way of example, and it is obvious to those skilled in the art that the grouping can be increased or decreased according to the actual needs. In addition, when M3 is greater than or equal to a third preset value Mf3, it indicates that the distribution is unsuccessful at this time, the distribution eccentric value is still larger, step S100 is returned again at this time, the number of times of failure is recorded once, and when the number of times of accumulated failure reaches P times, dehydration is stopped, and dehydration failure information is prompted; wherein P is a natural number of 1 or more.
With continued reference to fig. 2 and 3, step S630 further includes:
s631, controlling the clothes treatment equipment from the distribution rotating speed Vc1 to the pulse rotating speed Vd, and then reducing the pulse rotating speed Vd to the distribution rotating speed Vc1;
s632, repeating steps S610, S620 and S631 for N times until the dehydration is finished.
Through repeated pulse rotating speeds, clothes with different distribution eccentric values M3 can be dried to different degrees, and the smaller the eccentric value is, the better the drying is, so that a better drying effect is obtained.
In step S631, "again, the pulse rotation speed Vd is reduced to the distribution rotation speed Vc1" further includes:
s6311, firstly, reducing the pulse rotation speed Vd to a speed reduction rotation speed Ve;
s6312, the rotational speed Ve is increased from the deceleration rotational speed to the pulse rotational speed Vd, and the rotational speed Vd is decreased to the distribution rotational speed Vc1.
The increase of the deceleration rotation speed Ve is to drain water in the washing machine, the washing machine is not suitable for draining water at high speed, the whole unbalance can be caused, however, the speed is too low, and the re-acceleration difficulty can be caused, so that the buffer deceleration rotation speed Ve is arranged between the distribution rotation speed Vc1 and the pulse rotation speed Vd, the washing machine can drain water without too much deceleration, and the spin-drying process is optimized.
Step S632 further includes:
s6321, repeating steps S610, S620 and S631 for N-1 times;
s6322, repeating steps S610 and S620 on the nth time, then controlling the clothes treatment equipment to continuously run for delta Tb from the distribution rotating speed Vc1 to the pulse rotating speed Vd, and then from the pulse rotating speed Vd to the set rotating speed Vf;
s6323, the set rotation speed Vf is decreased to 0, and the dehydration is completed.
By directly increasing the pulse rotation speed to the set rotation speed Vf in the last spin-drying, deep spin-drying can be realized, and spin-drying is more thorough.
In summary, by increasing the preset rotation speed Vb1 and updating the distributed eccentricity value M3 in real time, the collision probability of the washing machine is greatly reduced, so that the washing machine is safer in use and longer in service life.
It should be noted that the above-mentioned embodiments are merely for illustrating the principles of the present invention, and are not intended to limit the scope of the invention, and those skilled in the art can modify the above-mentioned structure to apply the present invention to more specific application scenarios without departing from the principles of the present invention.
For example, in an alternative embodiment, the "steady operation at the rotation speed of the preset rotation speed Vb1 for t1 time" in step S300 of fig. 1 and the "steady operation at the rotation speed of the distributed rotation speed Vc1 for t2 time" in step S500 are all for making the washing machine perform the subsequent speed increase after the operation is more stable, but these obviously may be omitted, which do not deviate from the principle of the present invention, and therefore all fall within the scope of the present invention.
Further, the present invention provides a laundry treating apparatus including a controller capable of executing the dehydration control method mentioned in the present invention.
