The specific implementation manner of the operation of the pulsator washing machine started by the user is not limited.

In some embodiments, as shown in fig. 6, determining the washing parameters of the pulsator washing machine may be embodied as the following steps:

s201, acquiring the dry load weight of the washings and the materials of the washings.

Alternatively, as shown in fig. 7, step S201 may be specifically implemented as the following steps:

s2011, after receiving a starting instruction, acquiring the rotation power of the motor in a period of time, and acquiring a second image of the pulsator washing drum.

It can be understood that, in general, after the controller receives the start command, the controller controls the motor of the pulsator washing machine to start to work, so as to drive the pulsator washing drum to rotate for a period of time, so as to obtain the dry load weight of the current washings in the pulsator washing drum.

S202, determining washing parameters of the pulsator washing machine according to the dry load weight of the washing articles and the material quality of the washing articles.

In some embodiments, the washing mode of the pulsator washing machine includes a plurality of operating gears, one corresponding to each washing parameter, and the washing parameters include a washing spin-stop ratio, a balancing water-flow-stop ratio, and a washing water level. It can be understood that the washing stop ratio is the stop ratio of the pulsator washing tub in the washing process, and the balance water flow stop ratio is the stop ratio of the pulsator washing tub which makes laundry uniformly distributed for the first time after the washing of the laundry in the washing mode is finished, and the washing water level is the water level in the pulsator washing tub when the pulsator washing machine starts to wash.

In some embodiments, the memory of the pulsator washing machine stores a preset correspondence relationship among a dry load weight of laundry, a material of the laundry, and a working gear of a washing mode in advance. After the dry load weight of the current laundry and the material of the laundry are obtained, a target working gear corresponding to the dry load weight of the current laundry and the material of the laundry can be determined from a plurality of working gears based on the dry load weight of the current laundry, the material of the laundry and a preset corresponding relation.

After determining the target working gear according to the dry load weight of the washings, the materials of the washings and the preset corresponding relation, the washing parameter corresponding to the target working gear can be used as the washing parameter of the subsequent pulsator washing machine in a washing mode. And controls the pulsator washing machine to enter a washing mode with the washing parameter.

S102, after the end of the washing mode is detected, acquiring a first image of the pulsator washing drum.

In some embodiments, in order to timely acquire the current water level in the pulsator washing tub and the current height of the laundry after the washing mode is finished, the controller may detect the washing time of the pulsator washing machine in the washing mode in real time to determine when the washing mode is finished.

Optionally, the washing parameters further include a washing time period. After the controller controls the pulsator washing machine to enter a washing mode according to the washing parameters, the controller detects the current washing time length of the pulsator washing machine through the timer, and after the timer detects that the current washing time length of the pulsator washing machine reaches the washing time length included in the washing parameters, the controller determines that the washing mode is finished.

In some embodiments, after the end of the wash mode, the controller may acquire a first image of the pulsator washing tub through the image acquisition device.

S103, controlling the opening of the drain valve or the water inlet valve according to the first image so that the water level in the pulsator washing drum is lower than the height of the washed objects and the height difference between the water level in the pulsator washing drum and the height of the washed objects is within a preset interval range.

The preset interval range may be preset when the pulsator washing machine leaves the factory. For example, the preset interval ranges from 10 centimeters (cm) to 20cm, that is, the drain valve is controlled to be opened or the water inlet valve is controlled to be opened so that the water level in the pulsator washing tub is below the height of the laundry and the difference in height between the water level in the pulsator washing tub and the height of the laundry is between 10cm and 20 cm.

Alternatively, as shown in fig. 8, step S103 may be specifically implemented as the following steps:

s1031, performing image recognition on the first image to obtain the current water level height in the pulsator washing drum and the current height of washings.

In some embodiments, the controller may perform image recognition on the first image based on an image recognition technique to obtain a current water level height in the pulsator washing tub and a current height of laundry.

S1032, controlling the water inlet valve to be opened under the condition that the current height of the washings is above the current water level height and the height difference between the current height of the washings and the current water level height is above a preset threshold.

In some embodiments, when the controller detects that the current height of the laundry in the pulsator washing tub is above the current water level height and that the difference between the current height of the laundry and the current water level height is above a preset threshold, the controller controls the water inlet valve to be opened to increase the water level height in the pulsator washing tub so that the water level height in the pulsator washing tub is below the height of the laundry and that the difference between the water level height in the pulsator washing tub and the height of the laundry is within a preset interval. The preset threshold is preset when the pulsator washing machine leaves the factory, for example, the preset threshold is 21cm.

It can be understood that when the current height of the washings in the pulsator washing drum is detected to be above the current water level, and the difference between the current height of the washings and the current water level is above the preset threshold, the current height of the washings is represented to be greatly beyond the current water level, and if the pulsator washing drum is controlled to perform secondary uniform distribution in the state, the noise caused by the pulsator washing machine is large. Therefore, the water inlet valve is controlled to be opened, so that the water level in the pulsator washing drum is lower than the height of the washed objects, the height difference between the water level in the pulsator washing drum and the height of the washed objects is in a preset interval range, and larger noise is prevented from being caused when secondary uniform distribution is carried out subsequently.

The controller determines the opening duration of the water inlet valve according to the height difference between the current height of the washings and the current water level height, and the fixed flow rate of the water inlet valve, and further controls the opening duration of the water inlet valve corresponding to the opening duration of the water inlet valve when detecting that the current height of the washings in the pulsator washing tub is above the current water level height and the height difference between the current height of the washings and the current water level height is above a preset threshold.

In some embodiments, when the controller detects that the difference between the current height of the laundry and the current water level height reaches a preset threshold, the water inlet valve is controlled to be closed so as to stop water flow into the pulsator washing tub.

S1033, controlling the drain valve to be opened under the condition that the current height of the washings is below the current water level.

In some embodiments, when the controller detects that the current height of the laundry in the pulsator washing tub is below the current water level height, the controller controls the drain valve to be opened to reduce the current water level height in the pulsator washing tub, so that the water level height in the pulsator washing tub is below the height of the laundry and a height difference between the water level height in the pulsator washing tub and the height of the laundry is within a preset interval range.

It can be understood that when the current height of the washings in the pulsator washing drum is detected to be lower than the current water level, the current water level is represented to be higher than the current height of the washings, and if the pulsator washing drum is controlled to carry out secondary uniform distribution in the state, the uniform distribution effect is poor, and the eccentricity is still larger. Therefore, the drain valve is controlled to be opened, so that the water level in the pulsator washing drum is lower than the height of the washed objects, and the height difference between the water level in the pulsator washing drum and the height of the washed objects is within a preset interval range, thereby improving the uniform distribution effect of the secondary uniform distribution when the secondary uniform distribution is carried out subsequently.

Optionally, when detecting that the current height of the laundry in the pulsator washing drum is below the current water level, the controller determines the opening duration of the drain valve according to the height difference between the current height of the laundry and the current water level, and combines the fixed flow rate of the drain valve, so as to control the opening duration of the drain valve.

In some embodiments, when the controller detects that the difference between the current height of the laundry and the current water level reaches the preset interval range, the drain valve is controlled to be closed to stop draining the water in the pulsator washing tub.

S104, controlling the pulsator washing machine to enter a drainage mode.

In some embodiments, when the controller detects that the water level in the pulsator washing tub is below the height of the laundry and the height difference between the water level in the pulsator washing tub and the height of the laundry is within the preset interval range, the controller controls the pulsator washing machine to enter a drainage mode, and completes the secondary uniform distribution process in the drainage mode.

In some embodiments, controlling the pulsator washing machine to enter the drain mode may be embodied as: and controlling the water discharge valve to be opened, and controlling the pulsator washing drum to rotate in a preset direction and at a preset speed so as to discharge water in the pulsator washing drum from the water discharge valve.

The preset direction and the preset speed are preset when the pulsator washing machine leaves the factory, for example, the preset direction is clockwise and anticlockwise, and the preset speed is 75 revolutions per minute.

It can be understood that in the process of controlling the opening of the drain valve, the pulsator washing drum is controlled to rotate in a preset direction and at a preset speed, so that the secondary uniform distribution process of the washings is completed, the washings in the pulsator washing drum are uniformly distributed on the inner wall of the pulsator washing drum, and the noise generated in the subsequent dehydration process is reduced.

In some embodiments, when the pulsator washing drum is controlled to rotate in a preset direction and at a preset speed, the pulsator washing drum may be controlled to roll in this state for a preset time period, and the preset time period may also be preset when the pulsator washing machine leaves the factory, for example, the preset time period is 20 seconds (S).

In some embodiments, when the pulsator washing drum is controlled to rotate for a preset time period in a preset direction at a preset speed, the pulsator washing drum is controlled to rotate for a first preset time period in the preset direction at the preset speed, the rotation is stopped for the first preset time period, then the pulsator washing drum is controlled to rotate for a second preset time period in the preset direction at the preset speed, and the rotation is stopped for the second preset time period.

Illustratively, assuming the preset direction is clockwise, the preset speed is 75 revolutions per minute. After the drain valve is controlled to be opened, the pulsator washing drum is controlled to rotate clockwise, and the pulsator washing drum is controlled to rotate for 20s at the speed of 75 revolutions per minute, so that washings in the pulsator washing drum can be uniformly distributed on the inner wall of the pulsator washing drum; or, the pulsator washing drum is controlled to run for 4s in the clockwise direction at 75 rpm, the pulsator washing drum is stopped for 4s, and then the pulsator washing drum is controlled to run for 6s in the clockwise direction at 75 rpm, and the pulsator washing drum is stopped for 6s. The washing machine is operated periodically, so that noise generated during secondary uniform distribution is reduced, and washings can be uniformly distributed on the inner wall of the pulsator washing drum.

S105, controlling the pulsator washing machine to enter a dehydration mode when the water level in the pulsator washing cylinder is detected to drain to a preset dehydration water level.

In some embodiments, the pulsator washing machine is controlled to enter a dehydrating mode when it is detected that the water level in the pulsator washing tub is drained to a preset dehydrating level during the dehydrating mode of the pulsator washing machine.

Optionally, in the process that the pulsator washing machine is in the drainage mode, the controller acquires images in the pulsator washing cylinder in real time through the image acquisition device and performs image recognition so as to acquire the water level height in the pulsator washing cylinder in real time. When the water level in the pulsator washing cylinder is detected to be drained to a preset dehydration water level, the pulsator washing machine is controlled to enter a dehydration mode. Wherein, the preset dehydration water level is preset when the pulsator washing machine leaves the factory.

Optionally, after the controller detects that the opening time of the drain valve reaches the corresponding opening time through the timer, when the water level in the pulsator washing drum reaches the preset dehydration water level, the controller controls the drain valve to be closed, and controls the pulsator washing machine to enter a dehydration mode.

It can be understood that the water level in the pulsator washing machine is always reduced in the water draining process, when the controller detects that the water level in the pulsator washing machine is reduced to the preset water level, the water content in the pulsator washing machine is less, and the washed matters in the pulsator washing machine are uniformly distributed on the inner wall of the pulsator washing machine after being secondarily and uniformly distributed, so that the eccentricity of the washed matters is reduced, the water level in the pulsator washing machine is reduced when the water level in the pulsator washing machine is reduced, the generated noise is reduced, and the use experience of a user is improved.

Based on the embodiment shown in fig. 5, at least the following advantages are brought about: the embodiment of the application provides a control method of a pulsator washing machine, which is used for determining washing parameters of the pulsator washing machine after receiving a starting instruction of the pulsator washing machine. Wherein the washing parameters include a washing rotation stop ratio, a balancing water flow stop ratio and a washing water level. It can be understood that the balance water flow stop ratio is the first uniform distribution of the laundry after the laundry is washed by the pulsator washing tub in the washing mode. And then washing the washings and balancing water flow, wherein after balancing the water flow, the height difference between the washings and the water level in the pulsator washing cylinder is controlled to be kept within a preset interval range, so that the washings can be uniformly distributed on the inner wall of the pulsator washing cylinder after the pulsator washing machine enters a drainage mode. It can be understood that the pulsator washing machine controls the height difference between the washed objects and the water level in the pulsator washing drum to be kept in the preset interval range and then enters the drainage mode, and the second uniform distribution can be understood as the second uniform distribution of the washed objects, so that the eccentricity of the washed objects is reduced through the two uniform distribution, the vibration amplitude of the pulsator washing machine in the dehydration mode is reduced, the generation of larger noise is avoided, and the use experience of a user is improved.

A control method of a pulsator washing machine according to an embodiment of the present application is illustrated below with reference to a specific example. The control method comprises the following steps, as shown in fig. 9:

after receiving a starting instruction for controlling the pulsator washing machine to start, the controller obtains the weight and the material of the washing object through fuzzy weighing and image recognition, and determines washing parameters according to the weight and the material of the washing object. Wherein the washing parameters include: a washing rotation stop ratio, a balancing water flow stop ratio and a washing water level. After the end of the washing mode is detected, a first image of the washings and the water level in the pulsator washing drum is obtained, and the first image is identified to obtain the current height of the washings and the current water level height in the first image. If the current height of the washings is lower than the current water level, controlling the drain valve to be opened, and discharging water flow out of the pulsator washing drum at a fixed flow rate, so that the current height of the washings is 10cm-20cm higher than the current water level; if the current height of the washings is higher than the current water level, and the height difference between the current height of the washings and the current water level is higher than a preset threshold, controlling the water inlet valve to be opened, and enabling water flow to enter the pulsator washing drum at a fixed flow rate, so that the current height of the washings is 10cm-20cm higher than the current water level. When the current height of the washings is detected to be 10cm-20cm higher than the current water level, the drain valve is controlled to be opened, and the pulsator washing drum is controlled to rotate in a preset direction and at a preset speed, so that the pulsator washing machine performs a secondary uniform distribution process in a drainage mode, the washings are uniformly distributed on the inner wall of the pulsator washing drum, the eccentricity of the washings is reduced, and noise is reduced when the washings are dehydrated in a dehydration mode. And controlling the pulsator washing machine to enter a dehydration mode when the water discharge to a preset dehydration level is detected.
