110. After the first water inlet is finished, the first water level height acquired by the water level sensor is acquired, and the washing equipment is controlled to enter a washing stage.
The washing process of washing equipment such as washing machines mainly brings dirt into water for cleaning purposes under mechanical actions such as draining, scouring and the like generated by machinery and wetting and dispersing actions of detergents.
In an embodiment of the application, the washing equipment comprises a washing barrel. In washing, the washing object is first put into a washing tub. Wherein, the washing objects comprise clothes, hats, scarves, shoes, bedsheets, quilts and other articles needing washing. The washing apparatus includes a water inlet stage and a washing stage when washing the washing object. In the water inlet stage, the washing barrel is controlled to carry out the first water inlet, so as to prepare for washing. In the subsequent washing stage, the washing of the laundry may be achieved by draining, washing, and replenishing water.
In the embodiment of the application, the washing equipment can also comprise a water level sensor, wherein the water level sensor is used for collecting the water level in the washing barrel, and the water level of the washing barrel can be monitored through the water level sensor to control the washing barrel to perform the first water inlet. For example, during the water inflow process, the water level of the washing tub may be collected in real time by the water level sensor. When water is fed for the first time, water is fed continuously when the water level in the washing barrel does not reach the first water level, and water feeding is stopped when the water level in the washing barrel reaches the first water level.
Wherein the first water level may include a full load height and a half load height corresponding to a capacity of water filling the entire tub into the washing tub and a capacity of water filling half of the tub, respectively. It is understood that the first water level may also include other water levels, such as a 1/4 tank capacity level, a 3/4 tank capacity level, etc.
The first water level may be preset according to a washing requirement, or may be determined according to the weight of laundry loaded in the washing tub at the time of the next washing. For example, the washing weight of the washing object in the washing tub may be acquired, the first water level height may be determined according to the washing weight, and the water intake in the washing tub may be controlled to reach the first water level height at the time of the first water intake. When the water inlet of the washing barrel reaches the first water level, the water inlet is considered to be completed, the water inlet stage is ended, the first water level is obtained, and the washing equipment is controlled to enter the washing stage.
120. And in the washing stage, acquiring a second water level height acquired by the water level sensor.
After the washing stage is started, the washing device washes clothes in the washing barrel, for example, the washing device can comprise a motor, and the washing device drives the washing barrel to rotate through the motor, so that the washing device is washed.
In the embodiment of the application, after the washing stage is started for a first preset time, namely, after the washing time of the washing object reaches the first preset time, washing is paused. The first preset duration may be set as needed, for example, the first preset duration may be set to 5 minutes. After the water inflow was completed, the washing was suspended after washing the washing object for 5 minutes.
After the washing is suspended, the washing equipment is controlled to stand for a second preset time period, and the washing equipment does not wash the washing object within the second preset time period, so that the whole washing equipment is kept in a standing state.
After standing for a second preset time period, controlling the water level sensor to acquire the water level height after standing, namely the second water level height, and acquiring the second water level height acquired by the water level sensor.
The second preset duration may be set as needed, for example, the second preset duration may be set to 1 minute. After stopping the washing for 1 minute, the water level sensor is controlled to collect the second water level and obtain the second water level.
130. And acquiring a first difference value between the second water level height and the first water level height.
And subtracting the first water level of the washing barrel when the first water inlet is finished from the second water level of the washing barrel after washing for a first preset time period and standing for a second preset time period to obtain a first difference value. The first difference reflects a change in a water level height in the washing tub after the washing for the first preset time period and the resting for the second preset time period.
140. And if the first difference value is larger than or equal to a first preset threshold value, controlling the washing equipment to enter a defoaming stage.
In the embodiment of the application, whether a large amount of foam is generated in the washing barrel is judged by comparing the first difference value with the first preset threshold value. If the first difference value is larger than or equal to a first preset threshold value, a large amount of foam is generated in the washing barrel, foam removal is needed to be carried out in a defoaming stage, and if the first difference value is smaller than the first preset threshold value, a large amount of foam is not generated in the washing barrel, and the defoaming stage is not needed to be carried out.
The value of the first preset threshold can be set according to actual needs, so that power saving is realized while defoaming, and the value of the first preset threshold can be set larger. If the defoaming effect is desired to be higher, the value of the first preset threshold may be set smaller, for example, the first preset threshold may be set to 0, and when the second water level height-the first water level height is greater than or equal to 0, that is, the second water level height is greater than or equal to the first water level height, that is, the foam is removed in the defoaming stage.
In the embodiment of the application, the washing equipment further comprises a drain valve for controlling drainage and a pre-washing valve for controlling water inflow, and in the defoaming stage, the drain valve can be controlled to be opened and closed according to the first switching frequency, and the pre-washing valve is controlled to be opened and closed according to the second switching frequency.
For example, when entering the defoaming stage, the drain valve immediately starts draining and opens and closes at a first switching frequency of 45 seconds on/5 seconds off, while the pre-wash valve opens and closes at a second switching frequency of 2 seconds on/4 seconds off. Since the foam is water in nature, it is possible to achieve an antifoaming effect by inflow and drainage.
In the embodiment of the application, the pre-washing valve can be switched on and off for 4 times as a group, and a group (namely, 4 times) of switching is carried out every 4 minutes. In addition, in the defoaming stage, the motor may be controlled to rotate at a preset rotational speed, which may be set to 30rpm, and a preset rotation-stop ratio, which may be set to 2 seconds on/15 seconds off, for example. Defoaming is achieved by short rotation and long standing.
In other embodiments, during the defoaming stage, the foam may also be treated in the following manner: heating is stopped to reduce foaming and the operation of the washing apparatus is suspended.
Taking a drum washing machine as an example, if a change in water level in the washing machine is detected by a water level sensor due to bubbles in the washing machine, and a water level in the washing machine exceeds a preset threshold value by a water level sensor installed in the washing machine, a water temperature of laundry in the washing machine can be reduced by stopping heating of the drum washing machine, thereby reducing bubbles in the drum washing machine.
Here, since the drum washing machine has a warm water washing function, the solubility of the detergent can be increased to make the laundry fiber fluffy to enhance the laundry washing effect, but the increase of the water temperature increases the foam in the washing machine, so the water temperature in the washing machine can be reduced by stopping the heating, thereby reducing the foam in the washing machine.
If it is detected that the change in the water level in the washing machine is caused by foam in the washing machine and it is detected that the water level in the washing machine exceeds a preset threshold value by a water level sensor installed in the washing machine, it is possible to select to pause the operation of the washing machine.

In the water inlet stage, the washing barrel is controlled to carry out the first water inlet, so as to prepare for washing. In the subsequent washing stage, the washing of the laundry may be achieved by draining, washing, and replenishing water.
In the embodiment of the application, the washing equipment can also comprise a water level sensor, wherein the water level sensor is used for collecting the water level in the washing barrel, and the water level of the washing barrel can be monitored through the water level sensor to control the washing barrel to perform the first water inlet. For example, during the water inflow process, the water level of the washing tub may be collected in real time by the water level sensor. When water is fed for the first time, water is fed continuously when the water level in the washing barrel does not reach the first water level, and water feeding is stopped when the water level in the washing barrel reaches the first water level.
Wherein the first water level may include a full load height and a half load height corresponding to a capacity of water filling the entire tub into the washing tub and a capacity of water filling half of the tub, respectively. It is understood that the first water level may also include other water levels, such as a 1/4 tank capacity level, a 3/4 tank capacity level, etc.
The first water level may be preset according to a washing requirement, or may be determined according to the weight of laundry loaded in the washing tub at the time of the next washing. For example, the washing weight of the washing object in the washing tub may be acquired, the first water level height may be determined according to the washing weight, and the water intake in the washing tub may be controlled to reach the first water level height at the time of the first water intake.

In the embodiment of the application, after the washing stage is started for a first preset time, namely, after the washing time of the washing object reaches the first preset time, washing is paused. The first preset duration may be set as needed, for example, the first preset duration may be set to 5 minutes. After the water inflow was completed, the washing was suspended after washing the washing object for 5 minutes.

204. A first difference between the second water level and the first water level is obtained.
And subtracting the first water level of the washing barrel when the first water inlet is finished from the second water level of the washing barrel after washing for a first preset time period and standing for a second preset time period to obtain a first difference value. The first difference reflects a change in a water level height in the washing tub after the washing for the first preset time period and the resting for the second preset time period.
205. And judging whether the first difference value is larger than or equal to a first preset threshold value. If not, go to step 206, if yes, go to step 212.

If the first difference value is larger than or equal to a first preset threshold value, a large amount of foam is generated in the washing barrel, foam removal is needed to be carried out in a defoaming stage, and if the first difference value is smaller than the first preset threshold value, a large amount of foam is not generated in the washing barrel, and the defoaming stage is not needed to be carried out.
The value of the first preset threshold can be set according to actual needs, so that power saving is realized while defoaming, and the value of the first preset threshold can be set larger. If the defoaming effect is desired to be higher, the value of the first preset threshold may be set smaller, for example, the first preset threshold may be set to 0, and when the second water level height-the first water level height is greater than or equal to 0, that is, the second water level height is greater than or equal to the first water level height, that is, the foam is removed in the defoaming stage.
206. And after the water replenishing of the washing barrel is controlled for the last time, acquiring a third water level height acquired by a water level sensor.
In the washing stage, the water replenishing of the washing barrel can be controlled for multiple times. If the result of the determination in step 205 is that the first difference is smaller than the first preset threshold, it may be determined that a large amount of foam is not generated in the washing tub at this time, and then the third water level collected by the water level controller is obtained after the last control of water replenishment in the washing tub in the washing stage.
It should be noted that, the third water level is collected immediately after the last water replenishment, and represents the water level in the washing tub before the next washing is started after the last water replenishment.
207. And acquiring a preset rotation-stop ratio of the motor.
The washing equipment comprises a motor, and the clicking controls the washing barrel to start rotating from a static state and stop in the static state according to a preset rotating-stopping ratio. The washing device controlled by the motor rotates the washing barrel for a period of time and then stops, then rotates for a period of time and stops, and then reciprocates.
The preset rotation-stop ratio of the motor refers to the time ratio of the motor in a rotating state and in a static state in one rotation-stop. For example, the preset rotation stop ratio of the motor can be 10 seconds on/2 seconds off, and the rotation of the motor to the washing tub is controlled as follows: after each 10 seconds of controlling the rotation of the washing tub, the washing tub is stopped for 2 seconds, and then rotated for 10 seconds, and then stopped for 2 seconds, and so on.

210. And obtaining a second difference value between the third water level height and the fourth water level height.
And subtracting the water level in the washing process from the water level after the last water supplementing to obtain a second difference value. The second difference reflects the change in the height of the water level in the tub relative to the washing course after the last water replenishment.
211. And judging whether the second difference value is larger than or equal to a second preset threshold value. If not, go to step 214, if yes, go to step 212.
If it is determined in step 205 that a large amount of bubbles are not generated in the tub at the beginning of the washing, further, during the washing process, whether a large amount of bubbles are generated in the tub during the washing process may be continuously monitored by comparing the second difference value with a second preset threshold value. If the second difference value is greater than or equal to a second preset threshold value, a large amount of foam is generated in the washing barrel, foam removal is needed to be performed in a defoaming stage, and if the first difference value is less than the second preset threshold value, a large amount of foam is not generated in the washing barrel, and the defoaming stage is not needed to be performed.
The value of the second preset threshold can be set according to actual needs, so that energy and electricity are saved while defoaming is realized, and the value of the second preset threshold can be set larger. In order to pursue a higher defoaming effect, the value of the first preset threshold may be set smaller.
212. The washing device is controlled to enter a defoaming stage.
In the embodiment of the application, the washing equipment further comprises a drain valve for controlling drainage and a pre-washing valve for controlling water inflow, and in the defoaming stage, the drain valve can be controlled to be opened and closed according to the first switching frequency, and the pre-washing valve is controlled to be opened and closed according to the second switching frequency.
For example, when entering the defoaming stage, the drain valve immediately starts draining and opens and closes at a first switching frequency of 45 seconds on/5 seconds off, while the pre-wash valve opens and closes at a second switching frequency of 2 seconds on/4 seconds off. Since the foam is water in nature, it is possible to achieve an antifoaming effect by inflow and drainage.
In the embodiment of the application, the pre-washing valve can be switched on and off for 4 times as a group, and a group (namely, 4 times) of switching is carried out every 4 minutes. In addition, in the defoaming stage, the motor may be controlled to rotate at a preset rotational speed, which may be set to 30rpm, and a preset rotation-stop ratio, which may be set to 2 seconds on/15 seconds off, for example. Defoaming is achieved by short rotation and long standing.
213. After the defoaming stage is performed for a third preset time period, the washing equipment is controlled to finish the defoaming stage and enter the rinsing stage.
The third preset time period may be set to, for example, 20 minutes, and after the defoaming stage for 20 minutes is completed, the washing step is not repeated, and the washing object is directly rinsed in the rinsing stage, so as to clean the detergent.
214. The washing apparatus is not controlled to enter the defoaming stage.
