Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The washing machine and the dewatering control method and device with water according to the embodiment of the invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for controlling dehydration with water of a washing machine according to an embodiment of the present invention.
As shown in fig. 1, the dewatering control method for a washing machine with water according to an embodiment of the present invention includes the following steps:
and S1, acquiring the working current of the dehydration motor when the washing machine executes the pre-dehydration program.
Specifically, the user may select a suitable washing program according to the requirement of the laundry, and start the washing program to wash the laundry. When the washing machine executes the washing program, water can be fed according to the water level set in the washing program. After the water supply is completed, the inner tub of the washing machine starts to rotate to start washing the laundry. After the washing of the clothes is finished, the main drainage program can be executed for the first time, specifically, the drainage pump of the washing machine can be controlled to be started, and drainage is carried out according to the set time proportion of starting and stopping work until the drainage reaches the water level of the empty barrel. The preliminary dehydration process may be performed after the first main drainage process is finished.
When the dehydration motor operates according to the preset instruction in the pre-dehydration program, as shown in fig. 2, the operating current of the dehydration motor can be obtained through the current sampler of the dehydration motor.
And S2, judging whether the working current of the dehydration motor is larger than a preset current threshold value.
As shown in fig. 2, when the current sampler obtains the working current of the dehydration motor, the working current of the dehydration motor can be input to the a/D converter, the a/D converter performs a/D conversion, the working current after the a/D conversion is further fed back to the control chip, and the control chip determines whether the working current is greater than a preset current threshold.
And S3, if the working current of the dewatering motor is larger than the preset current threshold value, controlling the washing machine to execute a defoaming procedure, and detecting the water level in the inner barrel of the washing machine in real time when the washing machine executes the defoaming procedure.
In one embodiment of the present invention, when the operation current of the dehydration motor is less than or equal to the preset current threshold, the washing machine may be directly controlled to perform the main drainage process and the main dehydration process.
It should be understood that the operation current of the dehydration motor is affected by the water level and the amount of bubbles in the inner tub of the washing machine, and the more the amount of bubbles in the inner tub of the washing machine, the more the detergent and water remain in the inner tub of the washing machine. When the working current of the dewatering motor is less than or equal to the preset current threshold, the water level and the foam amount in the inner barrel of the washing machine are in a reasonable range, and at the moment, the washing machine can be normally controlled to execute a main drainage program and a main dewatering program.
When the working current of the dewatering motor is larger than the preset current threshold, the water level in the inner barrel of the washing machine is high, and at the moment, the problems that the working power of the dewatering motor is overhigh and the dewatering is unstable exist in the washing machine, so that the power consumption and the dewatering performance of the washing machine can be influenced, and the service life of the dewatering motor of the washing machine can be influenced.
In order to solve the above problem, when the operating current of the dewatering motor is greater than the preset current threshold, as shown in fig. 2, the control chip may output a control command to the dewatering motor to control the dewatering motor not to operate, and further control the washing machine to execute the defoaming program. The preset current threshold may be set according to an actual situation, for example, the preset current threshold may be set to 20% of a normal operation threshold of the dehydration motor. If the working current of the dehydration motor exceeds 25% of the normal working threshold value, the washing machine can be judged to be serious in dehydration with water.
And S4, judging whether the water level in the inner barrel is larger than a preset water level threshold value.
And S5, if the water level in the inner barrel is greater than the preset water level threshold, controlling a drainage pump of the washing machine to be started to drain water to the empty barrel water level.
In one embodiment of the present invention, the water level in the inner tub of the washing machine may be detected by a water level sensor or a water level switch while the washing machine performs a defoaming process.
Specifically, if the water level in the inner tub of the washing machine is detected by the water level sensor, the drain pump of the washing machine may be controlled to be turned on to drain water to an empty tub water level when the water level frequency is lower than a preset water level threshold, i.e., the water level in the inner tub is greater than the preset water level threshold. If the water level in the inner barrel of the washing machine is detected in real time through the water level switch, when the water level is higher than a preset water level threshold value, namely the water level in the inner barrel is higher than the preset water level threshold value, a drainage pump of the washing machine can be controlled to be started to drain water to the water level of an empty barrel.
That is, when the washing machine executes the defoaming program, if the water level in the inner drum of the washing machine is lower than the preset water level threshold, the washing machine is controlled to continue to execute the defoaming program to perform defoaming treatment; and if the water level in the inner barrel of the washing machine is greater than the preset water level threshold value, controlling a drainage pump of the washing machine to be started, and draining water generated by the defoaming procedure until the water is drained to the water level of the empty barrel.
In an embodiment of the present invention, as shown in fig. 3, after controlling the drain pump of the washing machine to be turned on to drain water to the empty tub water level, the following steps may be further included:
and S6, judging whether the time for the washing machine to execute the defoaming program reaches the preset time.
And S7, if the time for the washing machine to perform the defoaming process reaches a preset time, controlling the washing machine to perform a main draining process and a main dehydrating process.
Specifically, if the time for the washing machine to execute the defoaming procedure does not reach the preset time, the process continues to return to step S3, and the steps S3-S6 are executed in a loop, that is, the defoaming procedure and the operation of controlling the drainage pump to be turned on are continued until the time for the washing machine to execute the defoaming procedure reaches the preset time. After the time for the washing machine to execute the defoaming program reaches the preset time, the drainage pump of the washing machine can be controlled to be started, and the main drainage program is executed according to the set time ratio of starting and stopping the work until the drainage reaches the water level of the empty barrel. After the main dewatering program, the washing machine may be controlled to execute the main dewatering program until the time of the main dewatering program reaches the set time and the whole washing program is finished.
It should be noted that, if the washing program includes a plurality of pre-dewatering programs, each pre-dewatering program can adopt the above-mentioned dewatering control method for washing machine with water, so as to ensure that the clothes contain a relatively proper amount of water during dewatering with water, reduce the dewatering risk of washing machine with water well, prolong the service life of the dewatering motor, and ensure the safe and reliable operation of washing machine.
In order to make the present invention more clear to those skilled in the art, as shown in fig. 4, the method for controlling dehydration with water in a washing machine according to an embodiment of the present invention may include the following steps:
and S101, after the washing machine is started, water can be fed according to a set water level.
S102, the inner tub of the washing machine rotates to start washing the clothes.
And S103, after washing is finished, controlling a drainage pump of the washing machine to be started, and draining according to the set time proportion of starting and stopping work until the drainage reaches the water level of the empty barrel.
And S104, the washing machine executes a pre-dehydration program and acquires the working current of the dehydration motor.
And S105, judging whether the working current of the dehydration motor is larger than a preset current threshold value. If yes, go to step S110; if not, step S106 is performed. Wherein, the preset current threshold can be set to be 20% of the normal operation threshold of the dehydration motor.
And S106, controlling the washing machine to execute a defoaming program, and detecting the water level in the inner barrel of the washing machine in real time.
And S107, judging whether the water level of the washing machine is greater than a preset water level threshold value. If yes, go to step S108; if not, return to step S106.
And S108, controlling a drainage pump of the washing machine to be started, and draining water to the water level of the empty barrel.
And S109, judging whether the preset time of the defoaming program is reached. If yes, go to step S110; if not, return to step S106.
And S110, controlling the washing machine to drain water according to the set time proportion of starting and stopping the washing machine, and executing a main dewatering program after the water is drained to the water level of the empty barrel.
In summary, according to the dewatering control method for a washing machine with water according to the embodiment of the present invention, first, when the washing machine performs a pre-dewatering process, the operating current of the dewatering motor is obtained, and whether the operating current of the dewatering motor is greater than a preset current threshold is determined, if the operating current of the dewatering motor is greater than the preset current threshold, the washing machine is controlled to perform a defoaming process, then, when the washing machine performs the defoaming process, the water level in the inner tub of the washing machine is detected in real time, whether the water level in the inner tub is greater than the preset water level threshold is determined, and if the water level in the inner tub is greater than the preset water level threshold, the drainage pump of the washing machine is controlled to. According to the method, when the washing machine executes the pre-dehydration program, the working current of the dehydration motor is detected, whether water in the inner barrel of the washing machine is excessive can be judged, the defoaming program can be executed when the water in the inner barrel of the washing machine is excessive, water generated by defoaming is discharged in time when the defoaming program is executed, the risk of dehydration of the washing machine with water can be effectively reduced, the washing machine can be guaranteed to operate safely and reliably, and the service life of the dehydration motor can be prolonged.
Fig. 5 is a block diagram illustrating a dehydration control apparatus with water for a washing machine according to an embodiment of the present invention. As shown in fig. 5, the dewatering control device with water for a washing machine according to the embodiment of the present invention includes a current obtaining module 10, a current determining module 20, a control module 30, a water level detecting module 40, and a water level determining module 50.

The current judging module 20 is configured to judge whether the working current of the dewatering motor is greater than a preset current threshold. The control module 30 is configured to control the washing machine to execute a defoaming procedure when the operating current of the dehydration motor is greater than a preset current threshold. The water level detection module 40 is used for detecting the water level in the inner tub of the washing machine in real time when the washing machine performs a defoaming procedure. The water level judgment module 50 is used for judging whether the water level in the inner tub is greater than a preset water level threshold. The control module 30 controls the drain pump of the washing machine to be turned on to drain water to the empty tub water level when the water level in the inner tub is greater than the preset water level threshold.
Specifically, the user may select a suitable washing program according to the requirement of the laundry, and start the washing program to wash the laundry. When the washing machine executes a washing program, water can be fed according to a water level set in the washing program, and after the water is fed, the inner tub of the washing machine starts to rotate and the clothes start to be washed. After the washing of the clothes is finished, the main drainage program can be executed for the first time, specifically, the drainage pump of the washing machine can be controlled to be started, and drainage is carried out according to the set time proportion of starting and stopping work until the drainage reaches the water level of the empty barrel. The preliminary dehydration process may be performed after the first main drainage process is finished.
When the washing machine dehydration motor works according to the preset instruction in the pre-dehydration program, the current obtaining module 10 can obtain the working current of the dehydration motor.
Further, after the current obtaining module 10 obtains the working current of the dewatering motor, the working current can be fed back to the current judging module 20, and the current judging module 20 judges whether the working current of the dewatering motor is greater than a preset current threshold value.
In an embodiment of the present invention, the control module 30 may be further configured to directly control the washing machine to perform the main draining process and the main dehydrating process when the operating current of the dehydrating motor is less than or equal to the preset current threshold.
It should be understood that the operation current of the dehydration motor is affected by the water level and the amount of bubbles in the inner tub of the washing machine, and the more the amount of bubbles in the inner tub of the washing machine, the more the detergent and water remain in the inner tub of the washing machine. When the working current of the dewatering motor is less than or equal to the preset current threshold, the water level and the foam amount in the inner barrel of the washing machine are in a reasonable range, and at the moment, the washing machine can be normally controlled to execute a main drainage program and a main dewatering program.
When the working current of the dewatering motor is larger than the preset current threshold, the water level in the inner barrel of the washing machine is high, and at the moment, the problems that the working power of the dewatering motor is overhigh and the dewatering is unstable exist in the washing machine, so that the power consumption and the dewatering performance of the washing machine can be influenced, and the service life of the dewatering motor of the washing machine can be influenced.
In order to solve the above problem, when the operating current of the dehydration motor is greater than the preset current threshold, the control module 30 may output a control command to the dehydration motor to control the dehydration motor not to operate, and further control the washing machine to execute the defoaming program. The preset current threshold may be set according to an actual situation, for example, the preset current threshold may be set to 20% of a normal operation threshold of the dehydration motor.

If the water level in the inner tub of the washing machine is detected in real time through the water level switch, when the water level is higher than a preset water level threshold, that is, the water level in the inner tub is greater than the preset water level threshold, the drainage pump of the washing machine may be controlled to be turned on by the control module 30 to drain water to the empty tub water level.
That is, when the washing machine executes the defoaming program, if the water level in the inner tub of the washing machine is lower than the preset water level threshold, the washing machine is controlled by the control module 30 to continue to execute the defoaming program, and defoaming treatment is performed; if the water level in the inner tub of the washing machine is greater than the preset water level threshold, the control module 30 controls the drainage pump of the washing machine to be started, and water generated by the defoaming procedure is drained until the water level is drained to the empty tub water level.
In an embodiment of the present invention, as shown in fig. 6, the above-mentioned dewatering control device with water for a washing machine may further include a time judgment module 60. The time determination module 60 may be configured to determine whether a time for the washing machine to perform the defoaming procedure reaches a preset time after controlling the drainage pump of the washing machine to be turned on to drain water to an empty tub water level, wherein the control module 30 may be further configured to control the washing machine to perform the main drainage procedure and the main dehydration procedure when the time for the washing machine to perform the defoaming procedure reaches the preset time.
Specifically, when the time for executing the defoaming program of the washing machine does not reach the preset time, the working process of executing the defoaming program and controlling the drainage pump to be started is continued until the time for executing the defoaming program of the washing machine is judged to reach the preset time by the time judgment module 60.
