Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Embodiments of the present invention provide a rotation balancing method of a laundry treating apparatus, which will be described before describing the method. As shown in fig. 1, a laundry treating apparatus according to an embodiment of the present invention includes: the device comprises a water holding barrel 1, a dewatering barrel 2, a first balancer 3, a second balancer 4 and a water supply structure 5; wherein, the dehydration barrel 2 is positioned in the water barrel 1, the first balancer 3 is used for carrying out rotation balance in a first rotation speed stage of the dehydration barrel 2, the second balancer 4 is used for carrying out rotation balance in a second rotation speed stage of the dehydration barrel 2, and the rotation speed in the first rotation speed stage is less than that in the second rotation speed stage. The laundry treating apparatus may be a washing machine, a dryer, or a washing and drying all-in-one machine having a drying function.
In an application example, the clothes treatment apparatus is a pulsator washing machine, the first balancer 3 and the second balancer 4 are both disposed on the spin-drying tub 2, the first balancer 3 includes a plurality of water tanks disposed on an inner wall of the spin-drying tub 2 along a circumferential direction of the spin-drying tub 2, the second balancer 4 is disposed on a top of the spin-drying tub 2, the second balancer 4 includes a plurality of water storage chambers disposed at intervals along the circumferential direction of the spin-drying tub, the water storage tanks are not communicated with each other, and the water storage chambers and the water tanks are disposed in one-to-one correspondence. The second balancer 4 has water inlets respectively communicated to the water storage chambers, and the water supply structure 5 includes water supply pipes corresponding to the water inlets. A water guide pipe 6 is arranged between the water storage cavity and the corresponding water tank, and each water tank is also provided with a drainage pipe 7 for drainage. It can be understood that, in the first rotation speed stage, after the water flow introduced from the water flow inlet enters the water storage cavity, because the gravity of the water flow is greater than the centrifugal force of the water flow under the rotation action of the dehydration barrel, the water flow in the water storage cavity flows into the water tank through the water guide pipe 6 to perform rotation balance on the dehydration barrel in the water tank; at the second rotational speed stage, along with the increase of rotational speed, by the rivers of rivers entry leading-in water storage chamber, centrifugal force under the rotation effect of dehydration bucket is greater than the gravity of rivers for rivers store in the water storage intracavity, rotate the equilibrium to the dehydration bucket in the water storage intracavity. Illustratively, a cover plate 8 is provided on the tub 1, and the cover plate 8 is positioned above the second balancer 4 provided on the spin-drying tub 2.
In an embodiment of the present invention, in order to detect the eccentricity of the spin-drying tub 2, the laundry treating apparatus further includes: a hall switch sensor for detecting the rotation speed of the dehydration tub 2 and a hall displacement sensor for detecting the vibration displacement of the dehydration tub 2, the laundry treating apparatus may determine the eccentricity amount corresponding to the dehydration tub based on the detection data of the hall switch sensor and the hall displacement sensor.
As shown in fig. 2, the method for controlling the rotation balance of the laundry machine according to the embodiment of the present invention includes:
step 201, in a first rotating speed stage, controlling a water supply structure to supply water to a first balancer based on the detected eccentricity of a dewatering barrel;
and 202, controlling a water supply structure to supply water to the second balancer based on the detected eccentricity of the dewatering barrel in the second rotating speed stage.
So, at the first rotational speed stage of low rotational speed, control the water supply structure based on the eccentric amount that detects and supply water for first balancer, at the second rotational speed stage of high rotational speed, control the water supply structure based on the eccentric amount that detects and supply water for second balancer, can realize that clothing treatment facility is in the complete rotation balance of low rotational speed and high rotational speed stage, effectively avoided passive liquid balance ring can not be balanced even can increase eccentric defect under low rotational speed to clothing treatment facility's rotation balance effect has effectively been improved.
Exemplarily, in step 201, controlling the water supply structure to supply water to the first balancer based on the detected eccentricity amount of the dehydration tub in the first rotation speed stage includes:
comparing the eccentricity detected based on at least one first preset rotating speed corresponding to the dehydrating barrel in the first rotating speed stage with a first threshold value of the corresponding rotating speed, and if the detected eccentricity is greater than or equal to the first threshold value, controlling a water supply structure to supply water to a first balancer until the detected eccentricity is less than the first threshold value so as to accelerate the dehydrating barrel to a second rotating speed stage;
the first threshold corresponds to a first preset rotating speed one by one.
It is understood that, the first rotation speed stage may preset at least one first preset rotation speed, and each first preset rotation speed has a corresponding first threshold, and the first threshold may be determined based on a test, and is used as a criterion for determining whether the detected eccentricity amount needs to be subjected to rotation balance at the corresponding first preset rotation speed.
Here, the first preset rotation speeds may be set to two or more, and thus, the rotation balance control may be performed based on the comparison result of the eccentricity amounts detected at the plurality of first preset rotation speeds with the corresponding first threshold values in the first rotation speed stage, and the influence of unreliable detection of the eccentricity amounts on the rotation balance control in the low rotation speed stage may be effectively reduced.
In an application example, the first speed stage comprises two first preset speeds S1, S2, wherein S1< S2. If the eccentric amount detected in S1 is greater than or equal to the first threshold corresponding to S1, the water supply structure needs to be controlled to supply water to the first balancer, so that after the eccentric amount detected in S1 is less than the first threshold corresponding to S1, the rotation balance control of S2 is skipped, and the second rotation speed stage is directly started; if the eccentric amount detected at S1 is less than the first threshold corresponding to S1, after accelerating to S2, it is determined at S2 whether the rotation balance control is necessary, and if the eccentric amount detected at S2 is greater than or equal to the first threshold corresponding to S2, it is necessary to control the water supply structure to supply water to the first balancer so that the eccentric amount detected at S2 is less than the first threshold corresponding to S2, and the second rotation speed stage is entered. For the case that the first rotation speed stage has more than two first preset rotation speeds, the same can be said, and the description thereof is omitted.
In some embodiments, controlling the water supply structure to supply water to the first balancer includes:
determining a target water tank to be supplied with water and the water supply amount of the target water tank based on a phase angle representing the direction of the eccentric amount and an amplitude representing the magnitude of the eccentric amount;
and controlling the water supply structure to supply water based on the determined target water tank and the water supply amount of the target water tank.
For example, the laundry treating apparatus may acquire a pulse signal detected by a hall switch sensor and a displacement signal detected by a hall displacement sensor; determining an amplitude and a phase angle of the eccentricity amount based on the pulse signal and the displacement signal; wherein the pulse signal indicates the phase angle of the dewatering drum at different moments, and the displacement signal indicates the vibration displacement of the dewatering drum at different moments. For example, the pulse signal and the displacement signal may be processed based on a cross-correlation method to extract the magnitude and phase angle of the eccentricity amount of the dehydration tub. Here, the cross-correlation method, that is, the correlation between two signals based on time variation, may specifically adopt Fast Fourier Transform (FFT) or Discrete Fourier Transform (DFT), and the embodiment of the present invention is not particularly limited in this respect.
Here, a first vector corresponding to the eccentricity amount may be determined based on the phase angle and the magnitude of the acquired current eccentricity amount of the dehydration tub, and a second vector for rotational balance having a direction opposite to and a magnitude equal to that of the first vector is generated, a water supply ratio between the target tanks and each of the target tanks is determined based on the direction and magnitude of the second vector, and the total amount of water to be supplied is determined based on the magnitude of the second vector, and the amount of water to be supplied to each of the target tanks is distributed based on the water supply ratio, thereby achieving rotational balance of the eccentricity.
In an application example, it is assumed that the water tanks in the first balancer are arranged at intervals of 120 degrees, as shown in fig. 3, X1、X2、X3Respectively representing three tanks, vector FuRepresenting the direction and magnitude of the eccentricity, vector FbRepresenting the direction and magnitude of the balance, namely: fu＝-Fb(ii) a According to the sine theorem, X can be calculated1Balance of water tank Fx1And X2Balance of water tank Fx2Namely:
and based on Fx1And Fx2The ratio of the amount of water supplied to the target tank is determined. For other balance calculations, and so on.
In some embodiments, controlling the water supply structure to supply water to the first balancer further comprises:
determining that the amplitude value is in an increasing trend in the water supply process of the water supply structure, and controlling the water supply structure to interrupt water supply;
comparing the eccentric amount after the water supply is interrupted with a first balance limit value of the corresponding rotating speed;
if the eccentricity is smaller than the first balance limit value after the water supply is interrupted, controlling the dehydration barrel to accelerate to a second rotating speed stage;
if the eccentric amount after the water supply is interrupted is greater than or equal to the first balance limit value, controlling the clothes treatment equipment to stop;
the first balance limit value corresponds to a first preset rotating speed and is larger than a corresponding first threshold value.
Here, the laundry treating apparatus may filter (e.g., median filter) the amplitude and phase of the extracted eccentricity amount, and compare two adjacent filtered amplitudes to obtain a variation trend of the amplitude, and if the amplitude is increased, it indicates that the continuous water supply does not effectively improve the eccentricity of the rotation, control the water supply structure to interrupt the water supply, and determine whether the laundry treating apparatus can continue to dehydrate based on the eccentricity amount after the interruption of the water supply.
It will be appreciated that the first equilibrium limit value, which is reasonably determined on a trial basis, is more redundant than the first threshold value since it corresponds to the first preset rotation speed and is greater than the corresponding first threshold value, as long as the detected eccentricity is less than the first equilibrium limit value, the laundry treating apparatus can continue to spin, otherwise the laundry treating apparatus stops draining, waiting for manual treatment.
In some embodiments, the rotational balancing method further comprises, after the water supply is interrupted and before the comparing of the eccentricity after the water supply interruption with the first balancing limit value of the corresponding rotational speed: the water supply structure is controlled to supply a set amount of water to the tank corresponding to the target tank from which water was supplied last time.
Here, since the water supply is interrupted only after the amplitude value is increased, the water supply structure may be controlled to supply water in a reverse direction (i.e., to supply water to the tank opposite to the target tank from which water was supplied last time) so that the eccentric amount of the rotational balance reaches a preferred level, and then, based on the detected eccentric amount, it is determined whether the laundry treating apparatus can continue to dehydrate, and specifically, if the detected eccentric amount is less than the first balance limit value, the dehydrating tub is controlled to accelerate to the second rotation speed stage; and if the detected eccentricity amount is greater than or equal to the first balance limit value, controlling the clothes treatment equipment to stop.
In some embodiments, the rotational balance control method further comprises:
determining that the water supply frequency of any water tank is over or the water supply frequency of the first rotating speed stage is greater than the first frequency;
comparing the detected eccentricity with a first equilibrium limit value of the corresponding rotation speed;
if the detected eccentric amount is smaller than the first balance limit value, controlling the dewatering barrel to accelerate to a second rotating speed stage;
and if the detected eccentricity amount is greater than or equal to the first balance limit value, controlling the clothes treatment equipment to stop.
Here, if there is overflow of the water tank or the number of times of water supply is over, it indicates that the eccentricity of rotation cannot be effectively improved based on water supply, at this time, it needs to be judged whether the laundry treating apparatus can continue to dehydrate based on the comparison of the detected eccentricity amount with the first balance limit value, specifically, if the detected eccentricity amount is less than the first balance limit value, the dehydrating tub is controlled to accelerate to the second rotation speed stage; and if the detected eccentricity amount is greater than or equal to the first balance limit value, controlling the clothes treatment equipment to stop. It is understood that the first number can be chosen appropriately according to the requirements.
In an embodiment of the present invention, the second rotation speed stage includes: a plurality of second preset rotation speeds, controlling the water supply structure to supply water to the second balancer based on the detected eccentricity of the dehydrating tub at a second rotation speed stage, including:
aiming at each second preset rotating speed, comparing the detected eccentric amount with a second threshold value of the corresponding rotating speed, and if the detected eccentric amount is greater than or equal to the second threshold value, controlling a water supply structure to supply water to a second balancer until the detected eccentric amount is less than the second threshold value, so that the dewatering barrel is accelerated in sequence until the dewatering rated rotating speed is reached;
and the second threshold corresponds to a second preset rotating speed one by one.
It can be understood that, a plurality of second preset rotation speeds may be preset in the second rotation speed stage, and each second preset rotation speed has a corresponding second threshold, and the second threshold may be determined based on a test and used as a criterion for determining whether the detected eccentricity amount needs to be subjected to rotation balance at the corresponding second preset rotation speed. Here, the laundry treating apparatus may perform the determination of the rotational balance at each second preset rotational speed of the second rotational speed stage, and control the water supply structure to supply water to balance the eccentricity of the rotation by the second balancer if the rotational balance is required.
In some embodiments, the second balancer is located on the spin-drying tub and includes a plurality of water storage chambers arranged at intervals in a circumferential direction, and the control water supply structure supplies water to the second balancer, including:
determining a target water storage cavity to be supplied with water and the water supply amount of the target water storage cavity based on the phase angle representing the direction of the eccentric amount and the amplitude representing the magnitude of the eccentric amount;
and controlling the water supply structure to supply water based on the determined target water storage cavity and the water supply amount of the target water storage cavity.
It can be understood that the clothes treatment device can obtain the pulse signal detected by the hall switch sensor and the displacement signal detected by the hall displacement sensor; the magnitude and phase angle of the eccentricity amount are determined based on the pulse signal and the displacement signal. The clothes treatment equipment determines a first vector corresponding to the eccentricity based on the acquired phase angle and amplitude of the current eccentricity of the dewatering barrel, generates a second vector which is opposite to the first vector in direction and equal in size and is used for rotation balance, determines a water supply proportion between the target water storage cavity and each target water storage cavity based on the direction and size of the second vector, determines the total water quantity needing water supply based on the size of the second vector, and then distributes the water supply quantity of each target water storage cavity based on the water supply proportion, so that the eccentric rotation balance is realized. For a specific determination process, reference may be made to the calculation process of the balance amount shown in fig. 3, which is not described herein again.
In some embodiments, the rotational balance control method further comprises:
determining that the amplitude value is in an increasing trend in the water supply process of the water supply structure, and controlling the water supply structure to interrupt water supply;
comparing the eccentric amount after the water supply is interrupted with a second balance limit value of the corresponding rotating speed;
if the eccentric amount after the water supply is interrupted is less than a second balance limit value, controlling the dewatering barrel to accelerate to a next second preset rotating speed;
if the eccentric amount after the water supply is interrupted is greater than or equal to the second balance limit value, controlling the clothes treatment equipment to stop;
the second balance limit value corresponds to a second preset rotating speed and is larger than a corresponding second threshold value.
Here, the laundry treating apparatus may filter (e.g., median filter) the amplitude and phase of the extracted eccentricity amount, and compare two adjacent filtered amplitudes to obtain a variation trend of the amplitude, and if the amplitude is increased, it indicates that the continuous water supply does not effectively improve the eccentricity of the rotation, control the water supply structure to interrupt the water supply, and determine whether the laundry treating apparatus can continue to dehydrate based on the eccentricity amount after the interruption of the water supply.
It will be appreciated that the second equilibrium limit value, which is reasonably determined on a trial basis, may be more redundant than the second threshold value as long as the detected eccentricity is less than the second equilibrium limit value, which corresponds to the second preset rotation speed and is greater than the corresponding second threshold value, and the laundry treating apparatus may continue to spin, otherwise the laundry treating apparatus stops draining, waiting for manual treatment.
In some embodiments, after the water supply is interrupted and before the comparing based on the eccentricity after the water supply interruption with the second equilibrium limit value for the corresponding rotational speed, the method further comprises:
and controlling the water supply structure to supply the set water quantity to the water storage cavity corresponding to the target water storage cavity supplied with water last time.
Here, since the water supply is interrupted only after the amplitude value is increased, the water supply structure may be controlled to supply water in a reverse direction (i.e., to supply water to the water storage chamber opposite to the target water storage chamber supplied with water last time) so that the eccentric amount of the rotational balance reaches a preferred level, and then, based on the detected eccentric amount, it is determined whether the laundry treating apparatus can continue to dehydrate, specifically, if the detected eccentric amount is less than the second balance limit value, the dehydrating tub is controlled to accelerate to the next second preset rotation speed; and if the detected eccentricity amount is greater than or equal to the first balance limit value, controlling the clothes treatment equipment to stop.
In some embodiments, the rotational balance control method further comprises:
determining that the water supply frequency of the second rotating speed stage is greater than the second frequency;
comparing the detected eccentricity with a second equilibrium limit value of the corresponding rotation speed;
if the eccentric amount is smaller than the second balance limit value, controlling the dewatering barrel to accelerate to the next second preset rotating speed;
and if the eccentricity amount is greater than or equal to the second balance limit value, controlling the clothes treatment equipment to stop.
Here, if the number of times of water supply is over, it indicates that the eccentricity of the rotation has not been effectively improved based on the water supply, and at this time, it is required to judge whether the laundry treating apparatus can continue the dehydration based on the comparison of the detected eccentricity amount with the second equilibrium limit value, and specifically, if the detected eccentricity amount is less than the second equilibrium limit value, the dehydration tub is controlled to be accelerated to the next second preset rotation speed; and if the detected eccentricity amount is greater than or equal to the first balance limit value, controlling the clothes treatment equipment to stop. It will be appreciated that the second number may be chosen appropriately according to requirements.
The following describes the rotation balance control method according to the embodiment of the present invention in further detail with reference to the application examples.
In the application example, after the controller of the washing machine acquires the displacement signal detected by the hall displacement sensor and the pulse signal detected by the hall switch sensor, the rotating speed, the period, the frequency and the like of the dewatering drum can be determined, the amplitude value and the phase angle of the eccentricity are extracted based on the cross-correlation method, the amplitude value and the phase angle are subjected to median filtering, the amplitude values after two adjacent median filtering are compared, the change trend of the amplitude value can be judged to be increased or decreased, and the change trend of the amplitude value, the phase angle, the rotating speed and the amplitude value corresponding to each moment can be obtained.
