The term "plurality" means two or more unless otherwise specified.

At present, the commonly used full-automatic washing machines mainly comprise two types, one type is a pulsator washing machine, and the other type is a roller washing machine. The pulsator washing machine has one inner tub set inside the washing tub and capable of rotating around the central axis of the tub, one pulsator set in the bottom of the inner tub and capable of rotating coaxially with the inner tub, and the inner tub and the pulsator have rotating shaft perpendicular to the ground. The washing process mainly depends on the rotation of the impeller to drive water flow to rotate, and in the clothes dewatering process, clothes are easy to accumulate on one side of the inner barrel, so that the mass center of the inner barrel deviates from the rotation axis of the inner barrel, and the damage to the parts of the washing machine and the reduction of the service life are caused. In the prior art, some washing machines are provided with a balance ring on an inner barrel, balance liquid is filled in the balance ring, and under the condition that the inner barrel is offset, the balance liquid automatically flows to the opposite side of the offset to play a balance role. In the dehydration process of the washing machine, the inner barrel and the outer barrel are easy to collide, once the distance between the inner barrel and the outer barrel exceeds a threshold value or the collision occurs, the washing machine stops running immediately, and a user needs to manually adjust and restart the washing machine.

Fig. 1 is a schematic cross-sectional view of a pulsator washing machine according to an embodiment of the present disclosure; fig. 2 is a schematic cross-sectional view of a balancing apparatus according to an embodiment of the present disclosure. Referring to fig. 1 and 2, the pulsator washing machine includes an inner tub 200, a balancing ring disposed at the top of the inner tub, a balancing unit 300 disposed on the inner wall of the inner tub, and an outer tub 100. The balancing device 300 is used to dynamically balance and adjust the center of gravity of the inner tub 200. The balancing apparatus 300 includes a housing 310 and a linkage assembly 320. The upper part of the side wall of the housing 310 is provided with a water inlet 312, and the bottom part is provided with a water outlet 311 connected with a drainage channel of the pulsator washing machine. The shell 310 and the inner wall of the inner barrel 200 enclose a water containing cavity 330. While the washing operation starts to fill the inner tub 200 with water, the water enters the water receiving chamber 330 along the water inlet 312 until the water in the water receiving chamber 330 is as high as the water in the inner tub 200. Linkage assembly 320 includes an extension 321, a cover plate 322, and a drive assembly 323. The protruding part 321 is connected to the casing 321 through an elastic member 324, and includes a first end portion 3211 and a second end portion 3212 opposite to the first end portion 3211, the first end portion 3211 is located between the inner tub 200 and the outer tub 100, and has a gap with the outer tub 100; the second end 3212 is located within the water cavity 330. The cover 322 is disposed at the water outlet 311 and hinged to the housing 310. Drive assembly 323 the drive assembly 323 includes a first link 3231, a second link 3232, and a crankshaft 3233, the first link 3231 coupled to the second end 3212, the second link 3232 coupled to the cover 322, and the crankshaft 3233 coupled to the first link 3231 and the second link 3232.

After the washing operation is finished, the center of gravity of the inner tub is shifted due to the uneven distribution of the laundry in the inner tub 1. When the center of gravity of the inner tub 200 deviates from the center of mass and the distance between the inner tub 200 and the outer tub 100 is reduced until the first end portion 3211 of the protruding portion 321 and the outer tub 100 are pressed against each other, the elastic member 324 is compressed, at this time, the protruding portion 321 applies force to the first connecting rod 3231, one end of the crankshaft 3233 connected with the second connecting rod 3232 receives downward acting force, the other end of the crankshaft 3233 moves upward, thereby driving the second connecting rod 3232 to drive the cover plate 322 to move upward, opening the water outlet 311, and when the inner tub 200 is completely balanced with the outer tub 100, the water outlet 311 stops draining, thereby adjusting the center of gravity of the inner tub 200 and improving the balance performance of the pulsator washing machine. Alternatively, an even number of the balancing devices 300 are equally and uniformly disposed along the circumferential direction of the inner wall of the inner tub 200.

Referring to fig. 3, an embodiment of the present disclosure provides a method for controlling a pulsator washing machine including an inner tub and a balancing ring disposed at a top of the inner tub, the method including:

s11, a first actual position of the gimbal is determined.

And S12, controlling the pulsator washing machine to carry out pre-dehydration treatment under the condition that the first actual position of the balance ring meets the first set condition.

Before the clothes are dehydrated, the balancing device automatically adjusts the inner barrel according to the change of the gravity center of the inner barrel to finally reach a relatively balanced state, and meanwhile, a first actual position of the balancing ring is determined. Under the condition that the first actual position of the balance ring meets the first set condition, the inner barrel of the pulsator washing machine is in a relatively balanced state, and the pulsator washing machine can be controlled to carry out pre-dehydration treatment. Therefore, the probability of machine halt caused by collision of the inner barrel and the outer barrel can be reduced, and the operating efficiency and stability of the pulsator washing machine are improved.

By adopting the method for controlling the pulsator washing machine, after the rinsing mode is finished, according to the deviation value of the first actual position and the initial position of the balance ring monitored in real time, the pulsator washing machine is subjected to pre-dehydration treatment before dehydration operation and is matched with the balance device arranged on the side wall of the inner barrel of the pulsator washing machine. By controlling the impeller washing machine to carry out pre-dehydration treatment and matching with the dynamic balance adjustment of the balancing device to the inner barrel, the impeller washing machine realizes the stable transition from rinsing to dehydration, reduces the collision between the inner barrel and the outer barrel, reduces the operation of users and improves the operating efficiency of the impeller washing machine.

In some embodiments, the first setting condition includes: the deviation value of the first actual position of the balance ring and the initial position is less than or equal to a first set value; or, within a first preset time period, the deviation value of the first actual position of the balance ring and the initial position is continuously less than or equal to a first set value. Therefore, the time for starting the pre-dehydration treatment of the pulsator washing machine is accurately controlled, the working time of the pulsator washing machine is shortened, and the efficiency is improved.

The balance ring is arranged at the top of the inner barrel, and the initial position of the balance ring means that after water injection is completed in the washing stage of the pulsator washing machine, the gravity center of the inner barrel is positioned on the central shaft of the inner barrel, and the central shaft of the inner barrel is coincided with the central shaft of the outer barrel. The first actual position of the balance ring refers to the position of the balance ring detected in real time after the washing process of the washing machine is finished and before the pre-dehydration treatment is carried out.

Alternatively, the displacement of the balance ring is detected by equidistantly and uniformly arranging a plurality of displacement sensors on the inner wall of the outer barrel of the pulsator washing machine. Optionally, after the pulsator washing machine finishes injecting water, the displacement sensor detects the position of the balance ring and records the position as data of the initial position. Optionally, after the washing operation of the pulsator washing machine is finished, the displacement sensor detects the displacement of the balance ring from the initial position as data of the first actual position of the balance ring, transmits the data of the first actual position of the balance ring to the control device of the pulsator washing machine, and the control device determines the deviation value of the first actual position of the balance ring from the initial position.

Alternatively, the displacement sensors measure the first actual position of the gimbal once at equal intervals, for example, the intervals may be 1s, 2s, 5s, 8s, or 10 s. Optionally, the interval duration is set by a manufacturer according to different washing modes when the pulsator washing machine leaves a factory. Optionally, the interval duration is set by the user according to actual conditions. In this way, accurate measurements of the first actual position of the gimbal at different times can be achieved. Optionally, a first actual position of the gimbal is determined when the gimbal moves to the same position as the initial position. Thus, the influence of the inner barrel on data can be avoided.

Alternatively, in the case that the deviation value of the first actual position of the balance ring from the initial position is less than or equal to the first set value, it indicates that the inner tub of the pulsator washing machine is in a balanced state, and the pulsator washing machine may be controlled to perform pre-dehydration treatment. Alternatively, the first set value may range from 5mm to 20mm, for example the first set value may be 5mm, 8mm, 10mm, 14mm, 17mm or 20 mm.

Optionally, in a first preset time period, when a deviation value of the first actual position of the balance ring from the initial position is continuously less than or equal to a first set value, it indicates that the inner tub of the pulsator washing machine is in an equilibrium state, and the pulsator washing machine may be controlled to perform pre-dehydration. Optionally, the first preset duration ranges from 20s to 40 s. Optionally, the first preset duration is in a range of 30s to 50 s. Optionally, the first preset time period ranges from 40s to 60 s. Optionally, the plurality of sensors detect a data value of the first actual position of the gimbal, and transmit the data to the control device, and compare the data value with the data value of the initial position of the gimbal to obtain an offset value between the first actual position and the initial position of the gimbal, and then calculate an average value of the offset values. Optionally, in a first preset time period, under the condition that an average value of deviation values of the first actual position and the initial position of the balance ring is continuously smaller than or equal to a first set value, controlling the pulsator washing machine to perform pre-dehydration treatment. Therefore, the accuracy of the deviation value can be improved, the control accuracy of the pulsator washing machine can be improved, and the stability of the pulsator washing machine is guaranteed.

Alternatively, the angle of the balance ring deviating from the central axis of the inner barrel/outer barrel is detected by uniformly arranging a plurality of angle sensors on the inner wall of the outer barrel of the pulsator washing machine at equal intervals. Optionally, after the pulsator washing machine finishes injecting water, the angle sensor detects the position of the balance ring and records the position as data of the initial position. Optionally, after the washing operation of the pulsator washing machine is finished, the angle sensor detects the deviation angle displacement of the balance ring as data of the first actual position of the balance ring, transmits the data of the first actual position of the balance ring to the control device of the pulsator washing machine, and the control device determines the deviation angle value between the first actual position of the balance ring and the initial position. Alternatively, the angle sensors measure the actual position of the gimbal once at equal intervals, for example, the interval duration may be 1s, 2s, 5s, 8s, or 10 s. Optionally, the interval duration is set by a manufacturer according to different washing modes when the pulsator washing machine leaves a factory. Optionally, the interval duration is set by the user according to actual conditions.

Alternatively, after the washing operation is finished, the center of gravity of the inner tub is shifted due to the uneven distribution of the laundry in the inner tub. At the moment, the extension part of the balancing device on the unbalanced side in the inner barrel and the outer barrel are mutually extruded, the elastic element is compressed, the extension part applies force to the transmission assembly, and the second connecting rod of the transmission assembly drives the cover plate to move and open the water outlet, so that the gravity center of the inner barrel is adjusted.

In the process, the displacement sensor detects the position of the balance ring in real time, and the pulsator washing machine is controlled to carry out pre-dehydration treatment under the condition that the inner barrel and the outer barrel are balanced with each other, namely under the condition that the deviation value of the first actual position of the balance ring and the initial position is less than or equal to a first set value; or, in the first preset time, under the condition that the deviation value of the actual position of the balance ring and the initial position is continuously less than or equal to the first set value, controlling the pulsator washing machine to carry out pre-dehydration treatment.

In some embodiments, controlling the pulsator washing machine to perform the pre-dehydration process includes: controlling the inner barrel to rotate at a first speed.

And under the condition that the first actual position of the balance ring meets a first set condition, controlling the pulsator washing machine to carry out pre-dehydration treatment so as to enable the inner barrel to rotate at a first speed. In the process that the inner barrel rotates at the first speed, the clothes are distributed unevenly, and the gravity center of the inner barrel deviates from the mass center of the inner barrel due to the centrifugal force generated by the rotation of the inner barrel and the influence of the gravity action of the clothes on the balance of the inner barrel. The inner barrel rotates at a first speed, the balancing assembly autonomously adjusts the gravity center of the inner barrel, water in the balancing assembly is discharged, the gravity center of the inner barrel is continuously adjusted, in the process, the displacement sensor detects the displacement of the balancing ring deviating from the initial position in real time to serve as data of the second actual position of the balancing ring, the data of the second actual position of the balancing ring are transmitted to the control equipment of the pulsator washing machine, and whether the deviation value of the second actual position of the balancing ring and the initial position meets a second set condition is judged by the control equipment. Therefore, the real-time and accurate control of the pre-dehydration treatment can be realized, the control of the balance of the inner barrel is ensured, and the stability and the safety of the pulsator washing machine are improved.

And under the condition that the deviation value of the second actual position of the balance ring and the initial position meets a second set condition, the inner barrel is in a balanced state, and the dewatering operation stage can be started. Alternatively, the displacement sensors measure the actual position of the gimbal once at equal intervals, for example, the intervals may be 1s, 2s, 5s, 8s, or 10 s. Optionally, the interval duration is set by a manufacturer according to different washing modes when the pulsator washing machine leaves a factory. Optionally, the interval duration is set by a user.

Optionally, in the case that the second actual position of the balance ring does not satisfy the second set condition, the pulsator washing machine is controlled to continuously perform the pre-dehydration treatment, so that the inner tub continuously rotates at the first speed. The balancing device continuously adjusts the gravity center of the inner barrel while controlling the impeller washing machine to continuously perform pre-dehydration treatment to continuously rotate the inner barrel at the first speed, so that the inner barrel is stably operated. Like this, before carrying out the dehydration, carry out dehydration in advance to the adjustment of balancing unit to inner tub focus makes the steady dehydration of beginning of rotary drum washing machine operate, has reduced the risk that the impact of the interior bucket of direct start dehydration and urceolus leads to rotary drum washing machine to shut down, has improved rotary drum washing machine's factor of safety and steadiness ability, has improved user's use and has experienced.

Optionally, in a case that a deviation value of the first actual position of the balance ring from the initial position satisfies a first condition, controlling the pulsator washing machine to enter a pre-dehydration process, including: recording a first actual position before entering the pre-dehydration treatment, and setting the first actual position as an initial position of the pre-dehydration treatment; controlling the inner barrel to rotate at a first speed.

In some embodiments, the second setting condition includes: and within a second preset time length, the deviation value of the second actual position of the balance ring and the initial position is continuously less than or equal to a second set value. The dewatering of the pulsator washing machine is accurately and efficiently controlled.

Alternatively, the second set value may range from 0mm to 15mm, for example, the second set value may be 0mm, 3mm, 5mm, 10mm, 12mm or 15mm, depending on the actual situation. Optionally, the second preset time period ranges from 20s to 60s according to practical situations. Alternatively, the plurality of sensors detect the data value of the second actual position of the gimbal, and transmit the data to the control apparatus, and compare the data value with the data value of the initial position of the gimbal to obtain the deviation value between the second actual position and the initial position of the gimbal, and then calculate the average value of the deviation values. Alternatively, in the case that an average value of deviation values of the second actual position of the balancing ring from the initial position satisfies a second set condition, the pulsator washing machine is controlled to perform a spinning operation.

Optionally, the second setting condition includes: and within a second preset time length, the deviation value between the actual position of the balance ring and the initial position of the pre-dehydration treatment is continuously less than or equal to a second set value.

In some embodiments, controlling the pulsator washing machine to perform a dehydration operation includes: controlling the inner barrel to rotate at a second rotating speed.

and S31, determining a third actual position of the balance ring.

S32, it is determined whether the third actual position of the gimbal satisfies the third setting condition.

And S331, controlling the pulsator washing machine to perform pre-dewatering treatment again under the condition that the third actual position of the balance ring meets a third set condition.

S332, controlling the pulsator washing machine to continuously perform the dehydration operation under the condition that the third actual position of the balance ring does not meet the third set condition, and enabling the inner tub to continuously rotate at the second speed

And under the condition that the second actual position of the balance ring meets a second set condition, controlling the pulsator washing machine to carry out dehydration operation so as to enable the inner tub to rotate at a second speed. In the process that the inner barrel rotates at the second speed, the distribution of clothes is also uneven, the balance of the inner barrel is affected due to the centrifugal force generated by the rotation of the inner barrel and the gravity of the clothes, the gravity center of the inner barrel deviates from the mass center of the inner barrel, and the inner barrel needs to be adjusted at the moment. The balance assembly adjusts the gravity center of the inner barrel autonomously, water in the balance assembly is discharged, the gravity center of the inner barrel is adjusted continuously, in the process, the displacement sensor detects the displacement of the balance ring deviating from the initial position in real time to serve as data of a third actual position of the balance ring, the data of the third actual position of the balance ring are transmitted to the control device of the pulsator washing machine, and whether the deviation value of the third actual position of the balance ring and the initial position meets a third set condition or not is judged by the control device. And under the condition that the deviation value of the third actual position of the balance ring and the initial position meets a third set condition, the gravity center of the inner barrel is in a state of deviating from the mass center, and the adjustment is needed. Like this, make the operation of interior bucket safe, stable, the effectual problem of noise, vibration that appears of washing machine in the dehydration process of having solved has guaranteed washing machine's life, has promoted user and has used experience.

Alternatively, the displacement sensors measure the actual position of the gimbal once at equal intervals, for example, the intervals may be 1s, 2s, 5s, 8s, or 10 s. Optionally, the interval duration is set by a manufacturer according to different washing modes when the pulsator washing machine leaves a factory. Optionally, the interval duration is set by the user according to actual conditions.

And under the condition that the inner barrel rotates at the second rotating speed and the third actual position of the balance ring meets a third set condition, controlling the pulsator washing machine to carry out pre-dehydration treatment again, and continuously adjusting the gravity center of the inner barrel by the balance device. Therefore, through the pre-dehydration operation performed before dehydration, the gravity center of the inner barrel is adjusted by matching with the balancing device, the impeller type washing machine is ensured to be stably transited to the dehydration operation, the position of the balancing ring is detected in real time in the dehydration operation stage, the balance and the stability of the impeller type washing machine in the dehydration operation stage are further ensured, the problem of halt caused by the collision of the inner barrel and the outer barrel in the dehydration operation stage is reduced, once the third actual position of the balancing ring meets the third condition, the impeller type washing machine is controlled to perform the pre-dehydration treatment again, the inner barrel is changed from the operation at the second speed to the operation at the first speed, the phenomenon of halt caused by the collision of the inner barrel and the outer barrel is effectively reduced, and the dehydration speed is ensured to be efficiently completed.

Alternatively, in the case that the third actual position of the balancing ring does not satisfy the third set condition, the pulsator washing machine is controlled to continuously perform a spinning operation such that the inner tub is continuously rotated at the second speed. When the pulsator washing machine is controlled to continuously perform a dehydration operation, the inner tub is continuously rotated at a second speed, and the balancing device continuously adjusts the center of gravity of the inner tub to ensure that the pulsator washing machine rapidly performs a dehydration state and stably completes a dehydration process.

In some embodiments, the third setting condition includes: and within a third preset time length, the deviation value of the third actual position of the balance ring and the initial position is continuously greater than a third set value.

Alternatively, the third set value may range from 10mm to 30mm, for example, the third set value may be 10mm, 13mm, 18mm, 25mm or 30mm, depending on the actual situation. Optionally, the third preset time period ranges from 20s to 60s according to practical situations. Alternatively, the plurality of sensors detect the data value of the third actual position of the gimbal, and transmit the data to the control device, and compare the data value with the data value of the initial position of the gimbal to obtain the deviation value of the third actual position of the gimbal with the initial position, and then calculate the average value of the deviation values. Alternatively, in the case that the average value of the deviation values of the third actual position and the initial position of the balancing ring satisfies a third setting condition, the pulsator washing machine is controlled to perform the pre-dehydration process again.

Optionally, the third setting condition includes: and within a third preset time length, the deviation value of the third actual position of the balance ring and the initial position of the pre-dehydration treatment is continuously greater than a third set value.

At the later stage of the dewatering operation, moisture in the clothes is thrown out quickly, the weight of the clothes changes quickly, the distance between the inner barrel and the outer barrel changes sharply, the water amount in the balancing assembly is different at the moment, the centrifugal force generated by the inner barrel is also different, the balancing assembly drains water respectively according to the difference of the gravity center positions of the inner barrel, and the inner barrel is adjusted. When the pulsator washing machine is in a dehydration operation stage, firstly determining the water amount in the balancing device, and then determining the current position of the balancing ring, namely the fourth actual position, wherein the pulsator washing machine needs to adjust the pulsator washing machine by the water amount in the balancing device, when the balancing device is detected to be smaller than the preset water amount, the balancing device cannot continuously and automatically adjust the gravity center of the inner barrel, the pulsator washing machine is in a dangerous state, and when the deviation value of the fourth actual position of the balancing ring and the initial position is larger than the preset value in the fourth preset time period, the gravity center of the inner barrel is over-large in deviation and needs to be adjusted, but the water amount in the balancing device is insufficient at the moment, the gravity center of the inner barrel cannot be automatically adjusted to enable the inner barrel to reach a relatively balanced state, and then the pulsator washing machine is controlled to stop and give an alarm. Like this, thereby effectual solved in the dehydration operation stage because interior bucket deviate its focus to cause with outer bucket violent collision lead to the problem that the clothing machine shut down suddenly, before the condition of bucket and outer bucket striking appears, controlgear control washing machine shut down, guaranteed washing machine's life, promoted user's use and experienced.

Optionally, a water level sensor is arranged at the bottom of the water containing cavity of the balancing device and used for detecting the height of the water level in the water containing cavity. Optionally, the preset water level is in the range of 0-5 mm, for example, 0mm, 3mm or 5 mm. Optionally, the fourth preset time period is in a range of 10-30 s. Optionally, the fourth preset value ranges from 10mm to 30 mm. Therefore, the problem of sudden shutdown at the later stage of the dehydration stage can be effectively prevented, and the service life of the pulsator washing machine is prolonged.

In some embodiments, the first speed is less than the second speed. Thus, the operation speed of the inner tub at the time of the preliminary dehydration process is lower than that at the time of the dehydration operation. That is, before the dewatering operation, the inner tub is firstly operated at a low speed, the deviation value of the actual position of the balance ring and the initial position is detected in real time, and the gravity center of the inner tub is adjusted by matching with the balance device, so that the inner tub reaches a pre-balanced state before the dewatering operation, and then the inner tub enters a high-speed dewatering stage, thereby avoiding the collision problem of the inner tub and the outer tub caused by the sudden high-speed operation of the inner tub, reducing the shutdown problem of the pulsator washing machine caused by the collision of the inner tub and the outer tub, reducing the operation of users, and realizing the high-speed operation of the washing machine. The dynamic switching of the pre-dehydration treatment and the dehydration operation of the pulsator washing machine is controlled by monitoring the deviation value of the actual position and the initial position of the balance ring, so that the running balance of the pulsator washing machine is realized, and the efficiency of the pulsator washing machine is improved.
