Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, most of intelligent washing machines are simply restored after power failure, and the state of the intelligent washing machines is restored to be continuously operated when power failure occurs. For the user, after the power failure is recovered, the subsequent washing process is continued to be operated according to the original set time, so that the washing time is too long, and the use experience of the user is reduced.
The technical problem to be solved by the embodiment of the invention is that the existing washing machine runs the following washing process according to the original set time after the power failure recovery, so that the washing time is too long, and the control method and the control device for the power failure recovery of the washing machine and the washing machine are provided.
Example 1
As shown in fig. 1 to 3, the present invention provides a control method for recovering from power failure of a washing machine, which may include the steps of:
s1, when the washing machine recovers power supply from a power-off state, acquiring a working state of the washing machine during power-off;
the washing machine detects whether the abnormal condition of power failure occurs through the power failure detection device in operation, and at the moment of abnormal occurrence of power failure, the working parameters during power failure are stored through the memory in the controller, and the working parameters can include: working state, washing water temperature, washing residual time, dehydration rotating speed duration, power-off duration, clothes parameters, washing water level and the like.
When the washing machine is powered back from the power-off state, the working parameters stored in the memory are read by the controller, and the working state of the washing machine in the power-off state is confirmed from the working parameters. The working state of the washing machine includes a water inlet stage, a washing stage, a water discharge stage and a dehydration stage.
S2, when the working state of the washing machine in the power-off state is a washing stage, obtaining working parameters of the washing machine in the power-off state;
as shown in fig. 2, when the operation state of the washing machine at the time of power failure is a washing stage, the operation parameters stored in the memory are read by the controller, so that the normal operation of the washing machine at the time of power restoration can be restored by the operation parameters at the time of power failure.
And S3, determining the secondary washing time according to the preset relation between the working parameters and the secondary washing time.
When the washing machine enters the washing stage after power is restored, the laundry in the washing stage is always in the soak of the washing water. Therefore, the power-off time can be used as the laundry soaking action to reduce the washing time. For example, the power-off duration in the operating parameters may be obtained at this time, and the secondary washing time may be determined according to a preset relationship between the power-off duration and the secondary washing. The secondary washing time is the time it takes for the washing machine to continue washing the laundry after the power is restored.
The preset relationship between the power-off duration and the secondary washing may be a look-up table between the power-off duration and the secondary washing, or a relationship curve between the power-off duration and the secondary washing. Of course, the embodiment is only to illustrate the preset relationship between the operating parameter and the secondary washing time, but not limited thereto, and a person skilled in the art may change the type of the operating parameter or the preset relationship according to actual situations, so as to achieve the same technical effect.
By the arrangement, the working parameters of the washing stage of the washing machine in the power-off state are obtained, and the clothes are soaked in the washing barrel all the time after the power-off state, so that the soaking effect of the clothes can be used for reducing the washing time after the power-off recovery, and the longer the power-off time is, the longer the soaking time is, the more the washing time is reduced after the power-off recovery. Meanwhile, the combination of the water level and the weight of the clothes in the washing bucket is the soaking volume of the clothes and the soaking effect of the clothes, the higher the water level in the washing bucket is, the lighter the weight of the clothes is, the better the soaking effect is, and the more the washing time is reduced after the power failure is recovered. After the outage resumes, automatically regulated laundry parameter again reduces the washing time, makes the effect efficiency of doing washing reach the optimization, improves user's laundry and experiences the sense, and the laundry shows more intellectuality.
In a preferred embodiment of the present invention, the step S3 includes:
s31, determining the washing reduction time according to the preset relation among the washing residual time, the power-off time, the clothes parameters, the washing water level and the washing reduction time;
in the embodiment of the invention, the obtained working parameters can be power-off duration, clothes parameters and washing water level, and the washing reduction time is calculated according to the power-off duration, the clothes parameters and the washing water level. In the embodiment of the invention, the washing reduction time is reduced washing time after the power failure is recovered.
Specifically, a power-off memory module is arranged in the controller, the power-off duration can be obtained by judging the power-off duration through the power-off memory module of the controller according to time points before and after power-off, and the power-off duration can be divided into five gears, for example, the gear one is a gear one when the duration is less than one hour, the gear two is a gear two when the duration is greater than or equal to one hour and less than two hours, the gear three is a gear three when the duration is greater than or equal to two hours and less than four hours, the gear four is a gear four when the duration is greater than or equal to three hours and less than four hours, and the gear five is a gear five when the duration is greater than or equal to four hours.
Further, the laundry parameter may be a laundry weight grade, the laundry weight grade is a laundry weight grade distinguished by a weighing detection module of the washing machine controller, and the laundry weight grade may be distinguished by five gears, for example, 2kg, 4kg, 8kg, 10kg or more.
The washing water level is detected by a water level detection sensor of a washing machine controller, and four gears, namely a low water level, a middle water level and a high water level, are distinguished.
Of course, the skilled person can change the power-off duration, the laundry parameter, and the grade division of the washing water level according to the actual situation, and this embodiment is only for illustration and not for limitation, and can achieve the same technical effect.
The calculation method for calculating the washing reduction time by the power-off time length, the laundry parameter and the washing water level can also be realized by referring to the table.
S32, determining the secondary washing time based on the washing reduction time and the washing residual time.
Specifically, when the washing reduced time is less than the washing remaining time, a time difference value of the washing reduced time and the washing remaining time is determined based on the washing reduced time and the washing remaining time. And determining the secondary washing time according to the time difference.
For example, the preset washing time is one hour, twenty minutes have been washed when the power is off, so the washing remaining time is forty minutes. When the washing reduction time is determined, for example, the washing reduction time is fifteen minutes, the time difference between the washing reduction time and the washing remaining time is twenty-five minutes. The washing machine may determine the secondary washing time according to the time difference, and for example, may determine the secondary washing time to be between twenty-five minutes and thirty minutes.
Specifically, when the washing reduction time is equal to or greater than the washing remaining time, it can be directly considered that the time for which the laundry is soaked in the washing tub is sufficient for the dirt on the laundry to be dissolved and spread, thereby contributing to the washing effect of the laundry. Therefore, the washing stage can be directly controlled to stop, and the washing machine is controlled to enter the next working state.
Because different washing machines have different washing programs, for example, when the washing stage of the washing machine is finished, the next working state of part of the washing machine is the drainage stage, and then the washing machine is controlled to directly enter the drainage stage; and when the washing stage of the washing machine is finished, controlling the washing machine to directly enter the secondary washing stage if the next working state of part of the washing machine is the secondary washing stage.
The 10KG drum washing machine has the following specific conditions in the relation between washing reduction time, clothes weight grade and power-off time under the condition of 10L of washing water:
in an alternative embodiment of the present invention, as shown in fig. 3, the control method further includes:
s4, when the working state of the washing machine is in a dehydration stage when the power is off, judging whether the washing machine reaches a preset dehydration rotating speed before the power is off;
when the working state of the washing machine is a dehydration stage when the power is off, the working parameters stored in the memory are read by the controller, so that the normal operation of the washing machine when the power is restored can be restored through the working parameters when the power is off.
And reading the working parameters stored in the memory through the controller, confirming the actual dehydration rotating speed of the washing machine when the power is off from the working parameters, and then judging whether the actual dehydration rotating speed of the washing machine when the power is off reaches the preset dehydration rotating speed.
S5, if yes, judging whether the dewatering time of the washing machine reaching the preset dewatering rotating speed is more than half of the preset dewatering time before power failure;
if the actual dehydration rotating speed of the washing machine during the power failure reaches the preset dehydration rotating speed, whether the dehydration duration of the washing machine for dehydrating through the preset dehydration rotating speed during the power failure is greater than half of the preset dehydration time or not is obtained, namely whether the duration of the washing machine for dehydrating through the preset dehydration rotating speed during the power failure is greater than half of the preset dehydration time or not is obtained.
For example, the preset dehydration duration is two minutes, the preset dehydration rotation speed is one thousand eight hundred revolutions, and then there is a speed increasing process from the beginning of dehydration to the process that the actual dehydration rotation speed of the washing machine is increased to the preset dehydration rotation speed. For example, when the actual dehydration rotation speed is increased from zero to the preset dehydration rotation speed, it takes ten seconds, and the duration for the washing machine to complete the entire dehydration process by the preset dehydration rotation speed is one minute and fifty seconds. Therefore, in this embodiment, it is determined whether the duration of the dewatering operation performed by the washing machine at the preset dewatering speed is longer than one minute when the washing machine is powered off, i.e., the preset dewatering duration is half of two minutes.
S6, when the dewatering time of the washing machine reaching the preset dewatering rotating speed is more than half of the preset dewatering time, controlling the washing machine to dewater at the first rotating speed and continuing for the residual dewatering time;
and when the dewatering time of the washing machine reaching the preset dewatering rotating speed is more than half of the preset dewatering time, controlling the washing machine to dewater at the first rotating speed and continuing the residual dewatering time. The first rotating speed is smaller than the preset dehydration rotating speed, and the residual dehydration time is the difference between the preset dehydration time and the dehydrated time. For example, the first rotation speed may be a preset dehydration rotation speed reduced by one gear, and the dehydration at the reduced dehydration rotation speed of the first gear is just compensated for the other half of the duration that the dehydration at the preset dehydration rotation speed is not performed.
So set up, after the outage resumes, because the clothing is in accuse water state always, so at the outage in-process, moisture in the clothing constantly reduces, consequently, when half dehydration procedure has been carried out before the outage, can control washing machine and reduce the dehydration rotational speed, reduce the washing time, need not to dewater according to predetermineeing dehydration time and predetermineeing the dehydration rotational speed again, washing machine can reduce power consumption after the outage resumes like this, promotes energy-concerving and environment-protective.
Optionally, the control method further includes:
s7, when the duration of the washing machine reaching the preset dehydration rotating speed is less than or equal to half of the preset dehydration time, controlling the washing machine to detect the gravity center state of the clothes;
and when the duration of the washing machine reaching the preset dehydration rotating speed is less than or equal to half of the preset dehydration time, indicating that the duration of the actual dehydration of the washing machine at the preset dehydration rotating speed does not exceed half of the preset dehydration time, and dehydrating at the preset dehydration rotating speed.
At this time, it is necessary to re-detect the gravity center state of the laundry in the course of the washing machine increasing to the preset dehydration rotation speed. The higher the preset dehydration rotation speed is, the more uniform the gravity center state of the clothes in the washing machine is required, the longer the time for shaking the clothes in the dehydration is required, and the longer the final dehydration total time is. Conversely, the lower the spin rate, the less uniform the load drain condition of the garments in the cartridge, so that less time is required to fly the garments during spin-down and less total spin-down time is required.
And S8, determining the actual dehydration rotating speed based on the gravity center state of the clothes.
When the center of gravity of the clothes is not uniform, the actual dehydration rotating speed is reduced, so that the center of gravity of the clothes can be adjusted in the slow dehydration process; when the clothing focus in the washing machine is even, need tremble the clothes time in the dehydration and just need be more for a long time, can need to promote actual dehydration rotational speed to can promote dehydration effect.
Specifically, step S7 includes:
s71, controlling the washing machine to start a dehydration program, and starting dehydration according to a preset acceleration curve from acceleration to the preset dehydration rotation speed;
s72, acquiring a current acceleration curve of the washing machine;
and S73, determining the gravity center state of the clothes based on the current acceleration curve.
Specifically, step S73 includes:
when the current acceleration curve is lower than the preset acceleration curve, the clothes are in a first gravity center state, which indicates that the gravity center state of the clothes is poor;
when the current acceleration curve is higher than the preset acceleration curve, the clothes are in a second gravity center state, which indicates that the gravity center state of the clothes is better;
and when the current acceleration curve is equal to the preset acceleration curve, the clothes are in a third gravity center state, which indicates that the gravity center state of the clothes is normal.
Further, the above steps may include:
when the current acceleration curve is lower than the preset acceleration curve, the clothes are in a first gravity center state, and the washing machine is controlled to dewater at a first dewatering rotating speed lower than the preset dewatering rotating speed; at this time, the first dehydration rotation speed is lower than the preset dehydration rotation speed.
When the current acceleration curve is higher than the preset acceleration curve, the clothes are in a second gravity center state, and the washing machine is controlled to dehydrate at a second dehydration rotating speed higher than the preset dehydration rotating speed; the second dehydration rotation speed is higher than the preset dehydration rotation speed.
And when the current acceleration curve is equal to the preset acceleration curve, the clothes are in a third gravity center state, and the washing machine is controlled to dehydrate at the preset dehydration rotating speed.
When the power is off, the washing machine is in the water inlet stage or the water drainage stage, and the washing machine is controlled to continuously feed water or continuously drain water.
