Technical Field

The invention relates to the technical field of household appliances, in particular to a control method of a washing machine and the washing machine.

Background

The washing machine is a common household appliance, and greatly reduces the labor capacity of people.

When washing a piece of clothes which is easy to absorb water, such as towelling coverlet, summer quilt, woolen sweater, sweater and the like, the clothes are difficult to uniformly distribute in a roller, and the water content is high after the clothes are fully soaked due to more water absorption, so that the eccentricity is large, and spin-drying can not be performed at a high spin-drying rotating speed. The eccentric control logic of the washing machine is limited, so that the eccentric value is smaller than the preset value, sometimes even impossible to be smaller than the preset value, the problems of spin-drying alarm, spin-drying program delay, spin-drying rotating speed failing to meet the requirements and the like can occur, and the user experience is poor.

In the prior art, a balancing ball is arranged on a washing machine, the balancing ball generally adopts a steel ball, the steel ball can reduce the eccentric load value in a certain range in the dehydration stage, the action range of the balancing ball is in a proportional relation with the mass of the steel ball, once the eccentric value is larger, the steel ball cannot achieve a better balancing effect along with the rising of the dehydration rotating speed, the mass of the steel ball cannot be increased limitlessly, and the roller is deformed due to the combined action of the centrifugal force generated by the too large mass and the centrifugal force generated by the eccentric.

The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.

Example 1

Referring to fig. 1 to 6, an embodiment of the present invention provides a washing machine, including a drum assembly, a driving assembly 3 and a balancing assembly, the drum assembly includes an outer drum 1 and an inner drum 2 disposed inside the outer drum 1, a laundry inlet is formed at a front end of the inner drum 2, a rear end of the inner drum 2 is connected with the driving assembly 3, and the driving assembly 3 can drive the inner drum 2 to rotate around its own axis. The balance assembly comprises a plurality of balance balls, the inner cylinder 2 is provided with a containing cavity in a surrounding mode, the balance balls are movably arranged in the containing cavity, in the rotating process of the inner cylinder 2, the balance balls rotate along with the inner cylinder 2, namely, the containing cavity is used for limiting the movable space of the balance balls, and the balance balls can rotate in the containing cavity. Due to the centrifugal force and the friction force, a speed difference exists between the rotation speed of the balance ball and the rotation speed of the inner cylinder 2.

Specifically, the accommodating cavity may be directly disposed on the inner cylinder 2, but in order to reduce the modification of the existing structure, so as to reduce the modification of the mold and reduce the production cost, the inner cylinder 2 may be sleeved with the balance ring 4, and the accommodating cavity may be formed in the balance ring 4. The balancing ring 4 is detachably connected to the inner cylinder 2, for example by means of screws.

The balance ring 4 is provided with water passing holes 41, water in the inner cylinder 2 can enter the accommodating cavity through the water passing holes 41, and water in the accommodating cavity can also flow into the inner cylinder 2 or flow between the inner cylinder 2 and the outer cylinder 1.

The balancing ring 4 may be provided at the front, rear or middle of the inner barrel 2. One or more balance rings 4 may be provided.

At least part of the balance balls are water-absorbable balls. In the washing stage, the water-absorbing ball body absorbs water and weight is increased, and in the dewatering stage, when the rotating speed of the inner cylinder 2 reaches the set rotating speed V ₀ The water loss and weight loss of the water-absorbing sphere can be realized.

In the beginning stage of dehydration, the rotation speed of the inner cylinder 2 is smaller, the clothes lose water, but the balance balls do not lose water, the water content of the clothes in the washing machine is reduced, the eccentric value is further reduced, and as the inner cylinder 2 rotates, the balance balls and the clothes reach new balance. Along with the dehydration, the dehydration speed is increased, the water-absorbable spheres firstly lose a small amount of water and then lose water completely, and in the process, the water content of the clothes is continuously reduced, and the balance balls and the clothes continuously reach new balance. Because the balance ball can rotate in the accommodating cavity, the water can be gradually dehydrated through the water-absorbable ball body and the clothes, the balance ball and the clothes continuously reach new balance, the eccentric value is gradually reduced, the dehydration rotating speed can be stably increased, and the dehydration process is smoothly carried out.

Optionally, all the balance balls are divided into water-absorbable spheres and steel balls, and the water-absorbable spheres and the steel balls are alternately arranged. In the rotation process of the inner cylinder 2, the water-absorbable spheres and the steel balls are different in rotating speed due to different weights and different centrifugal forces, so that collision can occur between the water-absorbable spheres and the steel balls, and the friction force born by the steel balls can be increased.

Alternatively, the water-absorbable spheres are entirely made of a water-absorbable material. Or the water-absorbable sphere is divided into two parts, comprising an inner core body and a shell sleeved outside the core body, wherein the shell is made of water-absorbable materials.

According to the control method of the washing machine, in the dehydration stage, the dehydration parameters are determined according to the eccentric value, and if the eccentric value is large, high-speed dehydration is not easy to carry out. Specifically, the dehydration stage comprises:

s1, detecting an eccentric value of clothes;

s2, determining a dehydration parameter according to the eccentric value, and controlling the inner cylinder 2 to execute a dehydration process according to the dehydration parameter, wherein the dehydration parameter comprises the rotating speed and the rotating time length of the inner cylinder 2, and the dehydration process is divided into a high-speed dehydration process, a low-speed dehydration process and a balance correction process from large to small according to the rotating speed;

and S3, if the step S2 is performed by a low-speed dehydration process or a balance correction process, returning to the step S1 until the step S2 is performed by a high-speed dehydration process, and ending the dehydration.

It will be appreciated that in step 2, the balance correction process is at a minimum rotational speed and the high-speed dewatering process is at a maximum rotational speed. By means of the balancing correction process, the load in the inner cylinder 2 can be redistributed, thereby changing the eccentricity value. By the low-speed dehydration process, the laundry can be partially dehydrated, and the eccentricity value can be changed.

In this embodiment, the eccentricity value is a static eccentricity value, denoted by L0.

Referring to fig. 7, in the dehydrating stage, an eccentric value L0 of laundry is detected, whether L0 is less than L11 is judged, and when L0 is less than a first static set value L11, the inner tub 2 is controlled to perform a high-speed dehydrating process; when L0 is larger than the second static set value L12, controlling the inner cylinder 2 to execute a balance correction process; otherwise, the inner drum 2 is controlled to perform a low-speed dehydration process.

If the high-speed dehydration process is executed this time, the dehydration is ended. If the balance correction process or the low-speed dehydration process is executed this time, the eccentric value L0 is re-detected after the execution is completed, and the judgment is performed again.

In the low-speed dehydration process, the inner drum 2 may be controlled to dehydrate at a rotational speed less than V0 so that the laundry is dehydrated without the balance ball being dehydrated. The corresponding rotation speed and rotation duration may be determined according to the range in which L0 is located.

In particular, the low-speed dewatering process can be divided into two stages, including:

when L0 is within (L13, L12), controlling the rotating speed of the inner cylinder 2 to rise to a first rotating speed V11 for a first time period t11;

when L0 is within [ L11, L13], controlling the rotation speed of the inner cylinder 2 to rise to a second rotation speed V12 for a second time period t12;

wherein L11 is more than L13 and less than L12, and V11 is more than V0 and less than V12.

Because V11 < V0, when the rotation speed of the inner cylinder 2 is V11, the clothes lose water but the balance balls do not lose water, so that the water content of the clothes in the washing machine is reduced, and as the inner cylinder 2 rotates, the balance balls and the clothes reach new balance, so that the eccentric value is reduced.

Because V0 is less than V12, when the rotating speed of the inner cylinder 2 is V12, the clothes and the balance ball lose water, after the stage, the water content in the water-absorbable sphere is very small, and the influence of the weight of the water-absorbable sphere on the next eccentric detection is small.

In the balance correction process, the rotating speed of the inner cylinder 2 is V10, and the inner cylinder 2 rotates positively and negatively alternately, so that the clothes in the inner cylinder 2 are redistributed. Wherein V10 is less than V11, and the clothing is convenient for redistribute and can not lead to the sphere that can absorb water to lose water to the less rotational speed for the sphere that can absorb water can continue to exert the balancing action.

Alternatively, the low speed dewatering process can be divided into three stages, including:

when L0 is within (L13, L12), controlling the rotating speed of the inner cylinder 2 to rise to a first rotating speed V11 for a first time period t11;

when L0 is within [ L14, L13], controlling the rotation speed of the inner cylinder 2 to rise to a second rotation speed V12 for a second time period t12;

when L0 is within [ L11, L14], controlling the rotation speed of the inner cylinder 2 to rise to a third rotation speed V13 for a third time period t13;

wherein L11 is more than L14 and less than L13 is more than L12, V11 is more than V0 and less than V12 and less than V13.

It is understood that the low-speed dehydration process can be divided into two or more stages, and can be set according to practical situations.

In this embodiment, the rotational speed of the high-speed dehydration process may be 800rpm, and the duration may be set according to actual needs. V0 is obtained through multiple tests according to the actual situation of the water-absorbable sphere. For example, V12 is 200rpm and V13 is 400rpm.

Referring to fig. 8, between step S1 and step S2, further includes:

s11, if L0 is larger than L12, obtaining the number M1 of times of continuously executing the balance correction process, if M1 is larger than the set number M10, controlling the alarm device to be started, otherwise, executing S2;

s12, if L0 is smaller than or equal to L12 and larger than or equal to L11, the times M2 of continuously executing the low-speed dehydration process are obtained, if M2 is larger than the set times M20, the alarm device is controlled to be started, and otherwise, S2 is executed.

After the balance correction process or the low-speed dehydration process is performed for a plurality of times, the high-speed dehydration process is not performed, which means that the eccentricity of the load is serious and the load needs to be manually and timely processed.

Referring to fig. 9, between step S1 and step S2, further includes:

s11, if L0 is larger than L12, obtaining the number M1 of times of continuously executing the balance correction process, if M1 is larger than the set number M10, controlling the washing machine to execute the balance correction process, otherwise, executing S2;

s12, if L0 is smaller than or equal to L12 and larger than or equal to L11, the times M2 of continuously executing the low-speed dehydration process are obtained, if M2 is larger than the set times M20, the washing machine is controlled to execute the balance restoration process, and otherwise, S2 is executed.

In the balance restoration process, water is fed into the washing machine and the inner cylinder 2 rotates, the quality of the fed water is set to be the quality M, after the water feeding is finished, the eccentric value L0 of the clothes is detected again, and the L0 is compared, and the balance restoration method comprises the following steps:

and judging whether L0 is larger than L12, if so, controlling the alarm device to be started, and if not, continuing to judge. Judging whether L0 is smaller than L11, if yes, controlling the inner cylinder 2 to execute a high-speed dehydration process; otherwise, the inner drum 2 is controlled to perform a low-speed dehydration process.

After the high-speed dehydration process, the dehydration is ended; after the low-speed dehydrating process, the eccentricity value L0 of the laundry is re-detected. If the total dehydration duration exceeds the set total duration, the alarm device is controlled to be started if the dehydration is not finished yet.

The value of M20 may be set according to actual conditions, and specifically, may be set according to the water content of the laundry. When the water content is high, the low-speed dehydration may be performed several times more. Therefore, before step S1, it includes:

s0, acquiring the water content of the clothes in the inner cylinder 2, setting the times M20=M21 when the water content is larger than or equal to a first set water content, otherwise, setting the times M20=M22, wherein M21 is larger than M22.

For example m21=3, m22=2.

Example two

For simplicity, only the points of distinction between the second embodiment and the first embodiment will be described. The difference is that the eccentricity value also includes a dynamic eccentricity value N0, the dynamic eccentricity value being denoted N0. In some cases, the static eccentricity value is smaller, so that the inner cylinder 2 is suitable for rotating at a high speed, but the dynamic eccentricity value is larger, and the phenomenon that the inner cylinder 2 impacts the outer cylinder 1 can occur. For example, there is little clothing in the drum, the distribution of the clothing and the balance ball results in a small static eccentricity value, but the clothing and the balance ball are diagonally distributed, so that during the rotation of the inner drum 2, the clothing and the balance ball generate torque, resulting in a large dynamic eccentricity value.

In addition, the dynamic eccentricity value can be obtained only after the inner cylinder 2 is rotated, and the dynamic eccentricity value is changed in real time during the rotation of the inner cylinder 2. Therefore, in both the speed-up stage of the high-speed dehydration process and the speed-up stage of the low-speed dehydration process, it is necessary to detect the moving eccentricity value to determine whether the moving eccentricity value allows the inner tub 2 to be speed-up to a desired rotational speed.

Step S2 further includes:

when L0 is smaller than L11, in the process of increasing the speed of the inner cylinder 2, if N0 is larger than or equal to a first dynamic set value N11, controlling the inner cylinder 2 to reduce the speed and executing a balance correction process;

when L0 is smaller than or equal to L12 and larger than or equal to L11, in the process of increasing the speed of the inner cylinder 2, if N0 is larger than or equal to a second dynamic set value N12, controlling the inner cylinder 2 to reduce the speed and executing a balance correction process;

wherein N11 is less than N12.

It will be appreciated that in the process of performing high-speed dehydration, the inner cylinder 2 needs to be accelerated to 800rpm or 1000rpm, if the dynamic eccentricity value is large, the cylinder collision phenomenon will occur in the process of acceleration, so in order to avoid cylinder collision, the cylinder needs to be decelerated and corrected in time to change the eccentricity value, so that the dehydration is facilitated to be performed smoothly.

When L0 is smaller than L11, in the process of accelerating the inner cylinder 2, if N0 is smaller than a first dynamic set value N11, continuing to execute the high-speed dehydration process; when L0 is smaller than or equal to L12 and larger than or equal to L11, and in the process of accelerating the inner cylinder 2, if N0 is smaller than the second dynamic setting value N12, continuing to execute the low-speed dehydration process.

Whether the eccentricity value to be detected for this dehydration is a single static eccentricity value or a combination of static eccentricity value and dynamic eccentricity value is considered can be judged according to the weight of the wet load. The more the wet load is, the more densely distributed the inner cylinder 2, and the smaller the possibility of generating larger dynamic eccentricity is, so that under the condition of more wet load, only the static eccentricity value is needed to be referenced, the steps are saved, and the dehydration time is saved.

Specifically, step S1 includes: and acquiring a weight value of the wet load in the inner cylinder 2, wherein when the weight value is greater than or equal to a first set weight, the eccentric value is a static eccentric value L0, and otherwise, the eccentric value comprises the static eccentric value L0 and a dynamic eccentric value N0.

The embodiment of the invention also provides a washing machine, which is controlled by adopting the control method of the washing machine in any embodiment.
