Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious 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.
Although current handheld dust catcher can sanitation, but the dust catcher can make handheld dust catcher take place the stifled commentaries on classics when inhaling debris such as hair, wastepaper, the dust catcher gets into stifled commentaries on classics guard state, but when the stifled commentaries on classics of dust catcher emergence, its temperature can rise and lead to the electric current to diminish, the condition of stifled commentaries on classics erroneous judgement appears, then can't carry out the stifled protection and lead to the dust catcher to be burnt out, reduced the life of dust catcher.
Based on the technical scheme, whether the dust collector enters the locked rotor protection state or not is judged by judging whether the restart working current is greater than the current threshold value within the first preset time, the phenomenon that the dust collector is burnt out when the locked rotor does not enter the locked rotor protection state is avoided, and the service life of the dust collector is prolonged.
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for controlling a vacuum cleaner, wherein the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer-executable instructions, and wherein, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than that illustrated.
In this embodiment, a control method of a vacuum cleaner is provided, which can be used for a vacuum cleaner, such as a handheld vacuum cleaner, etc., and fig. 1 is a flowchart of a control method of a vacuum cleaner according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
and S11, when the cleaner is restarted, acquiring the time of the cleaner stopping the rotation blockage last time.
When the motor of the dust collector is blocked and stops, the dust collector can be restarted, and the time for the dust collector to be blocked and stopped is obtained. Specifically, the dust collector can be provided with a restart key, and a user can press the restart key to send a restart instruction to the dust collector. The vacuum cleaner can respond to the restart instruction to execute the restart operation of the vacuum cleaner, and when the vacuum cleaner is restarted, the vacuum cleaner can acquire the time of the last shutdown caused by the locked rotor. The time that the dust collector stops due to the rotation blockage can be stored in a storage unit in the dust collector, and when the dust collector is restarted, the dust collector can acquire the stop time that the dust collector stops due to the rotation blockage last time by inquiring the storage unit in the dust collector.
And S12, judging whether the time difference value between the current starting time and the stopping time is within the preset time threshold value.
The current starting time is the time corresponding to the successful restart of the dust collector. And (4) subtracting the current starting time from the stopping time to obtain a time difference value between the current starting time and the stopping time. The preset time threshold is the maximum restart time of the vacuum cleaner, the time difference value is compared with the preset time threshold to determine whether the time difference value is within the preset time threshold, and when the time difference value is within the preset time threshold, step S13 is executed, otherwise, other operations are executed, where the other operations may be detecting the working current of the vacuum cleaner, or detecting whether the vacuum cleaner is in a locked-rotor state, and the operation is not specifically limited here.
And S13, acquiring the restarting working current of the dust collector.
The restarting working current is the dust collection operating current after the dust collector is restarted. When the time difference value is within the preset time threshold value, the secondary starting of the dust collector is successful, and at the moment, the restarting working current when the secondary starting of the dust collector is successful can be obtained through the current detection device.
And S14, judging whether the restart working current in the first preset time length is larger than a current threshold value.
The first preset time is the locked-rotor state judgment time of the secondary starting of the dust collector motor, and the current threshold is the current value of the locked-rotor of the dust collector motor. And comparing the restarting working current with the current threshold value within a first preset time length, and determining whether the restarting working current is greater than the current threshold value within the first preset time length. When the restart operating current is greater than the current threshold, step S15 is executed, otherwise, the vacuum cleaner executes another operation, which may be to continue to detect the relationship between the restart operating current and the current threshold, or to execute a normal vacuum cleaning operation, and this is not limited specifically here.
And S15, judging that the dust collector enters a locked-rotor protection state, and stopping dust collection operation.
When the restarting working current is larger than the current threshold value, the motor of the dust collector is in a locked-rotor state, the locked-rotor protection state needs to be started, the dust collector is controlled to stop dust collection operation, and the dust collector is prevented from being burnt out due to the motor being locked.
According to the control method of the dust collector provided by the embodiment of the invention, when the dust collector is restarted within the preset time threshold, the dust collector is still in a locked-rotor state when being restarted due to the existence of the temperature of the first locked-rotor. Because the motor coil resistor of the dust collector is metal, when the dust collector is locked, the temperature in the dust collector rises, the coil generates heat, the longer the locked-rotor time is, the higher the coil temperature is, the higher the corresponding motor internal resistance is, and the motor voltage is unchanged, so that the restarting working current of the dust collector motor is reduced, the condition that the restarting working current is smaller than the current threshold value is caused, and the dust collector is not locked but burnt out due to the locked-rotor protection state. The method comprises the steps of judging whether the restarting working current is greater than a current threshold value within a first preset time period or not, and judging that the dust collector enters a locked-rotor protection state when the restarting working current is greater than the current threshold value within the first preset time period, and stopping working of the dust collector, so that misjudgment of the locked-rotor state of the dust collector is avoided. Through the accurate judgement to the stifled commentaries on classics state of dust catcher for the dust catcher can in time get into stifled commentaries on classics protection state when taking place the stifled commentaries on classics, avoids the dust catcher to be burnt out, has improved the life of dust catcher.
In this embodiment, a control method of a vacuum cleaner is provided, which can be used for a vacuum cleaner, such as a handheld vacuum cleaner, etc., and fig. 2 is a flowchart of a control method of a vacuum cleaner according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
and S20, acquiring the working current of the dust collector.
The working current is the motor current of the dust collector in the dust collection operation. The operating current may be obtained by a current sensing device, such as a current sensor, provided in the cleaner. Of course, the current may be obtained in other manners, and is not limited in particular, as long as the current of the motor of the vacuum cleaner during the dust collecting operation can be obtained.
And S21, judging whether the working current is larger than the current threshold value.
For the detailed description of the current threshold, refer to the corresponding related description of the above embodiments, and are not repeated herein. The operating current is compared to a current threshold to determine whether the operating current is greater than the current threshold. When the working current is greater than the current threshold, step S22 is performed, otherwise, a normal dust suction operation is performed.
And S22, acquiring the duration corresponding to the working current being greater than the current threshold.
When the working current of the dust collector is larger than the current threshold, the duration of the working current larger than the current threshold can be obtained. Specifically, a timing device can be arranged in the dust collector, and when the working current of the dust collector is detected to be larger than the current threshold, the timing device starts a timing function to determine the duration of the working current of the dust collector larger than the current threshold.
And S23, judging whether the duration is greater than a second preset duration.
The second preset time is the first locked-rotor state judgment time of the dust collector motor. In order to prevent a certain current instant value from rising, the motor is judged to be in a locked-rotor state by mistake, and the second preset time length can be set to be more than or equal to 20 seconds. And comparing the duration with a second preset duration, and determining the size relation between the duration and the second preset duration. When the duration is longer than the second preset duration, step S24 is executed, otherwise step S210 is executed.
And S24, entering a locked-rotor protection state and restarting the dust collector.
When the duration is longer than the second preset duration, the working current is continuously larger than the current threshold value and is not the instant increase of the current, the motor of the dust collector can be judged to be locked, the dust collector is controlled to enter a locked-rotor protection state, and the dust collector is restarted for the second time. Specifically, as long as the second preset time period is long enough, the motor cannot be determined to be in the locked-rotor state even if the ground is uneven and the working current is increased instantly. Because operating current's the grow in the twinkling of an eye also lasts for a few seconds, consequently predetermine for a long time more than or equal to 20 seconds through setting up the second, can accurately avoid appearing the condition of motor stalling. And if the working current is greater than the current threshold value for 20 seconds, controlling the dust collector to enter a locked-rotor protection state.
And S25, when the cleaner is restarted, acquiring the time of the cleaner stopping the rotation blockage last time. For a detailed description, refer to the related description of step S11 corresponding to the above embodiment, and the detailed description is omitted here.
And S26, judging whether the time difference value between the current starting time and the stopping time is within the preset time threshold value. When the time difference is within the preset time threshold, step S27 is executed, otherwise step S211 is executed.
And S27, acquiring the restarting working current of the dust collector when the time difference value is within a preset time threshold value. For a detailed description, refer to the related description of step S13 corresponding to the above embodiment, and the detailed description is omitted here.
And S28, judging whether the restart working current in the first preset time length is larger than a current threshold value.
The first preset time period is any value from 1 to 8 seconds, for example, the first preset time period may be 1 second, may be 2 seconds, may also be 4 seconds, and of course, may also be 8 seconds, and is not specifically limited herein. The second preset duration is greater than the first preset duration. When the motor of the dust collector is in a locked-rotor state, the current is increased, the internal temperature of the motor is increased, the internal resistance of a motor coil under a long time is increased due to the temperature, the voltage of the motor is unchanged, the current is reduced from large to small, the restarting working current value is smaller than the current threshold value, and the phenomenon of misjudgment of the motor of the dust collector can occur. At this time, the locked-rotor state judgment time of the secondary start can be changed from the second preset time to the first preset time, and whether the restarting working current in the first preset time is greater than the current threshold value is judged, so that the situation that the motor of the dust collector is in the locked-rotor state and the dust collector is burnt out without entering the locked-rotor protection state is avoided. And when the restart working current is larger than the current threshold, executing step S29, otherwise, executing normal dust collection operation.
And S29, when the restart working current is larger than the current threshold, judging that the dust collector enters a locked rotor protection state, and stopping dust collection operation. For a detailed description, refer to the related description of step S15 corresponding to the above embodiment, and the detailed description is omitted here.
And S210, controlling the dust collector to perform normal dust collection operation.
When the duration is less than or equal to the second preset duration, the current is increased instantaneously due to some factor, but the motor is not locked. At this time, the cleaner can continue to perform a normal cleaning operation.
And S211, judging that the dust suction operation is re-executed by the dust collector.
When the time difference value exceeds the preset time threshold value, the fact that the dust collector is restarted instead of being restarted when the motor is locked and stopped is indicated, the dust collector can execute dust collection operation again, and the locked and rotated state judgment time length is the second preset time length.
Specifically, taking the first preset time duration of 1 second and the second preset time duration of 20 seconds as an example, when the cleaner is started for the second time, due to the existence of the first locked rotor temperature, the secondary start is still in the locked rotor state, and the locked rotor state is still judged for 20 seconds after the secondary start, the current may be reduced due to the influence of the overlong time and the temperature rise, and the restarting working current is smaller than the current threshold, so that the cleaner will be misjudged, and the locked rotor of the cleaner is burnt out without entering the locked rotor protection state. A preset time threshold value is set between the first start and the second start, the locked rotor state judgment time of the secondary start dust collector is changed from 20 seconds to 1 second, and the phenomenon that the restarting working current is smaller than the current threshold value due to overlong time is avoided. When the starting time exceeds the preset time threshold value, the dust collector is judged to restart, and the locked rotor state judgment time is changed into 20 seconds.
According to the control method of the dust collector provided by the embodiment of the invention, whether the duration is longer than a second preset duration is judged by acquiring the duration that the working current of the dust collector is longer than the current threshold, and when the duration is longer than the second preset duration, a locked rotor protection state is entered, and the dust collector is restarted. Because the dust catcher is during normal work, its operating current can be because of blocking the object and grow suddenly at a certain instant, nevertheless not necessarily takes place the locked rotor, through obtaining the duration that operating current is greater than the electric current threshold value, only when duration is greater than the second and predetermines the duration, judges that the dust catcher motor is locked rotor, gets into locked rotor guard state, has guaranteed the judgement accuracy of locked rotor state. The locked-rotor state of the dust collector can be accurately judged by setting the first preset time to be 1-8 seconds, so that the error judgment of the locked-rotor state is avoided; and the second preset time length is set to be more than or equal to 20 seconds, so that the misjudgment of the locked rotor state caused by the rise of a certain current instant value is avoided.
