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 following describes an unlocking control method and device for a washing machine and the washing machine according to an embodiment of the invention with reference to the accompanying drawings.
Fig. 1 is a flowchart of an unlocking control method of a washing machine according to an embodiment of the present invention, as shown in fig. 1, the unlocking control method of a washing machine including:
s101, when the washing machine is detected to be powered on, the last stored tub rotating speed before the power-on is obtained.
In the embodiment of the invention, whether the washing machine is powered on or not can be detected through the computer board in the washing machine, namely whether a user presses a power key of the washing machine to start the washing machine or not, and when the washing machine is powered on, the last stored drum rotating speed before the power on is obtained, namely the drum rotating speed stored before the power off of the last time before the power on is obtained. As a feasible implementation manner, the last stored tub rotation speed before power-on may be obtained from a Memory storage chip (i.e., a Memory) disposed in the washing machine, and the Memory storage chip may be specifically a charged Erasable Programmable Read Only Memory (EEPROM).
S102, judging whether the barrel rotating speed is equal to or less than a preset barrel rotating speed threshold value.
In the embodiment of the invention, a threshold value of the rotating speed of the tub can be preset, the threshold value of the rotating speed of the tub can be a critical value of the safe rotating speed, when the rotating speed of the tub is equal to or less than the threshold value of the rotating speed of the tub, the rotating speed of the tub of the washing machine can be judged to be in the range of the safe rotating speed, and the threshold value of the rotating speed of the tub can be 55 revolutions per minute (rpm). After the barrel rotation speed is obtained in step S101, the barrel rotation speed is compared with a barrel rotation speed threshold, and it is determined whether the barrel rotation speed is equal to or less than a preset barrel rotation speed threshold.
And S103, if so, controlling the door lock to unlock.
In the embodiment of the invention, if the rotating speed of the barrel is equal to or less than the threshold value of the rotating speed of the barrel, the rotating speed of the barrel of the washing machine is in a safe rotating speed range, and the computer board of the washing machine sends out a trigger signal to control the door lock to be unlocked.
Further, the unlocking control method further includes: if not, controlling the frequency converter to be electrified and communicating with the frequency converter; if the communication is successful, judging whether the rotating speed of the motor is 0; and if the rotating speed of the motor is 0, controlling the door lock to unlock.
In the embodiment of the invention, if the rotating speed of the barrel is greater than the threshold value of the rotating speed of the barrel, because the difference time between the power-on time of the washing machine and the time for storing the rotating speed of the barrel at the last time is uncertain, whether the rotating speed of the washing machine barrel is in a safe rotating speed range at the moment can not be judged, the power-on of the frequency converter is controlled and the frequency converter is communicated, if the communication is successful, the rotating speed of the current motor is obtained from the frequency converter, if the rotating speed of the current motor is 0, the motor of the washing machine stops rotating at the moment, the rotating speed of the washing machine barrel is also 0 and is in the safe range, and the computer board of the washing machine sends a trigger signal to control the door lock to unlock.
Further, the unlocking control method further includes: if the rotating speed of the motor is greater than 0, the door lock is controlled to be unlocked after delaying the preset first time.
In the embodiment of the invention, the first time can be preset, if the rotating speed of the motor is greater than 0, the motor of the washing machine still runs at the moment, and the rotating speed of the washing machine barrel is also greater than 0, the preset first time is delayed, so that after the rotating speed of the washing machine barrel is reduced to a safe range, the computer board of the washing machine sends out a trigger signal to control the door lock to be unlocked. For example, the first time can be preset to be 1 minute, if the rotating speed of the motor is greater than 0, the time is delayed for 1 minute, and after the rotating speed of the washing machine barrel is reduced to be within a safety range, the computer board of the washing machine sends out a trigger signal to control the door lock to be unlocked.
Further, the unlocking control method further includes: and if the communication fails, delaying the preset second time and controlling the door lock to unlock.
In the embodiment of the invention, the second time can be preset, if the communication with the frequency converter fails, the second time is delayed, the computer board of the washing machine sends a trigger signal to control the door lock to unlock after the rotating speed of the washing machine barrel is reduced to a safe range. For example, the second time can be preset to be 1 minute, if the communication with the frequency converter fails, the delay is 1 minute, and after the rotating speed of the washing machine barrel is reduced to a safe range, the computer board of the washing machine sends out a trigger signal to control the door lock to be unlocked.
Further, before step S101, the tub rotation speed before the power failure when the washing machine operates last time before power on needs to be stored first, and as a feasible implementation, the method for storing the tub rotation speed before the power failure when the washing machine operates last time before power on may include: during the power-on operation process of the washing machine, the rotating speed of the barrel of the washing machine is detected and cached in real time, and when the fact that the washing machine is about to be powered off is detected, the current rotating speed of the barrel is stored in the storage, namely the last cached rotating speed of the barrel is stored in the storage.
In the embodiment of the invention, whether the washing machine is about to be powered down or not can be detected through the computer board in the washing machine, as a feasible implementation mode, a power down signal generated by triggering the power key can be detected, namely when a user presses the power key to close the washing machine, the fact that the washing machine is about to be powered down is judged; as another possible implementation, when the power-down signal is generated at the end of the washing time, it is determined that the washing machine is about to be powered down. And when detecting that the washing machine is about to be powered off, acquiring the last cached barrel rotating speed and storing the last cached barrel rotating speed into a memory.
Further, before step S102, the unlocking control method further includes: judging whether the door lock is locked; if yes, executing the step of judging whether the barrel rotating speed is equal to or less than a preset barrel rotating speed threshold value.
In the embodiment of the present invention, whether the door lock is locked or not may be detected by the computer board in the washing machine, and if it is determined that the door lock is locked, the step S102 is performed.
