Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
Laundry treatment apparatuses, such as washing machines, typically comprise a main control panel and a motor inverter (i.e. inverter), and the main control panel communicates with the motor inverter for driving the motor in operation to rotate the laundry treatment drum. When the washing machine is used in a severe environment and the driving command (instruction) is complicated, the washing machine can be subjected to external interference, so that communication errors between the main control board and the motor frequency converter are caused; or there may be human software writing errors. The errors can cause the washing machine to receive a reverse rotation instruction in the normal rotation instruction operation process, or the washing machine receives the normal rotation instruction in the reverse rotation instruction operation process, and the motor is directly locked, so that the washing machine is abnormal in operation.
In view of at least one of the above problems, an embodiment of the present disclosure provides a control method of a laundry treatment apparatus, where the method is applied to a frequency converter, and can trigger and execute a rotation protection program when a reverse rotation speed instruction is received during unidirectional operation of a motor, so as to implement abnormal protection, avoid direct locking (i.e. jamming) of the motor, and facilitate conversion of the laundry treatment apparatus into reverse operation, thereby implementing normal operation.
In some embodiments, an anomaly protection algorithm may be added based on the motor frequency converter to achieve reverse rotational speed anomaly protection.
In some embodiments, the control method is applied to a laundry treatment apparatus such as a drum washing machine, and may be performed in a laundry treatment process such as a washing course, a rinsing course, and the like of the laundry treatment apparatus, which is not limited herein.
In some embodiments, triggering and execution of the rotation protection procedure may specifically include: if the frequency converter receives a reverse rotation speed instruction (namely a reverse rotation speed instruction) in the normal operation process, the frequency converter automatically reduces the speed and even stops; if the rotating speed is reduced to be smaller than a preset rotating speed threshold value, enabling the rotating speed instruction in the opposite direction; if the rotating speed is still equal to or greater than the preset rotating speed threshold value, the reverse rotating speed command is not responded. Therefore, the motor locking phenomenon is avoided, abnormal damage of the clothes treatment equipment is avoided, continuous operation of the clothes treatment equipment is facilitated, and user experience is improved.
Control methods, devices, media, and laundry treatment apparatuses provided by embodiments of the present disclosure are exemplarily described below with reference to the accompanying drawings.
Exemplary, fig. 1 is a schematic flow chart of a control method according to an embodiment of the disclosure. The method is applicable to application scenes in which operation control of the motor in the clothes treatment equipment is required, and can be executed by the control device of the clothes treatment equipment provided by the embodiment of the disclosure, for example, the method can be executed by a controller (namely a motor frequency converter) in the clothes treatment equipment; the control means of the laundry treating apparatus may be implemented in software and/or hardware. As shown in fig. 1, the method comprises the steps of:
S110, receiving a reverse rotation speed command triggered in the unidirectional operation process of the motor.
In the embodiments of the present disclosure, the reverse direction is relative to the direction of the unidirectional operation process, specifically, the direction opposite to the direction of the unidirectional operation; the reverse rotational speed command may also be referred to as a reverse rotational speed command, or a reverse rotational speed command.
Illustratively, when unidirectional operation is forward rotation, reverse rotation speed is reverse rotation speed; this step corresponds to the receipt of a reverse rotational speed command during forward rotation of the motor. Or when the unidirectional operation is reverse rotation, the reverse rotation speed is the forward rotation speed; this step corresponds to the receipt of a forward rotation speed command during the reverse rotation of the motor.
In some embodiments, the reverse rotational speed instruction is generated based on a user operation or received based on a communication transmission.
In combination with the above, under the condition of severe use environment, the communication between the main control board and the motor frequency converter may be wrong, and the occurrence and the reception of the reverse rotation speed instruction may be caused due to the existence of the communication error. Or in the case of human software writing errors, the occurrence and reception of reverse rotation speed instructions is caused by software running errors. Or in the running process of the washing machine, a reverse rotating speed instruction is generated based on user operation and is transmitted to the main control board, and then is transmitted to the motor frequency converter.
In other embodiments, the reverse speed command may also be generated/triggered/presented based on other circumstances and received, without limitation. The embodiment of the disclosure mainly provides a method for performing operation protection on the abnormal reverse rotation speed instruction, which is described later.
And S120, triggering and executing a rotation protection program based on the reverse rotation speed instruction.
In the embodiment of the disclosure, the rotation protection program is used for carrying out corresponding abnormal protection on the reverse rotation speed instruction, so that the motor is prevented from being directly locked, the continuous operation of the motor is realized, the continuous normal operation of the clothes treatment equipment is facilitated, and the user experience is further improved.
In some embodiments, triggering and executing the rotation protection procedure may specifically include:
acquiring the current rotation speed of the unidirectional operation of the motor;
Judging whether the current rotating speed is equal to or greater than a preset rotating speed threshold value or not;
If the current rotating speed is equal to or greater than a preset rotating speed threshold value, controlling the current rotating speed to be reduced to a target rotating speed; the target rotational speed is less than a preset rotational speed threshold, and the selectable target rotational speed is equal to or greater than 0.
In the embodiment of the disclosure, the current rotation speed is a detection value based on the unidirectional operation rotation speed of the motor acquired by an encoder or other sensors; the preset rotation speed threshold is used for measuring whether the current rotation speed is too high, namely whether the speed needs to be reduced. Specifically, if the current rotation speed is equal to or greater than a preset rotation speed threshold, the current rotation speed indicating the unidirectional operation of the motor is higher, and at the moment, a reverse rotation speed instruction cannot be enabled continuously, but the current rotation speed needs to be reduced; until the current rotation speed is reduced to a target rotation speed which is smaller than a preset rotation speed threshold value.
In some embodiments, the target rotation speed may be 0, or a lower rotation speed greater than 0 and less than a preset rotation speed threshold, which may be understood as a rotation speed at which the motor is not directly locked when the reverse rotation speed command is enabled, so as to achieve continuous operation of the motor.
It should be noted that the specific value of the preset rotation speed threshold may be set based on the motor performance parameter and the requirement of the control method, which is not limited herein.
In some embodiments, if the current rotational speed is low, the reverse rotational speed command is directly enabled without causing the motor to lock directly. Specifically, the method may further comprise:
If the current rotation speed is smaller than the preset rotation speed threshold value, directly enabling the reverse rotation speed instruction.
In the embodiment of the disclosure, if the current rotation speed of the motor in one-way operation is smaller than the preset rotation speed threshold, the reverse rotation speed command can be directly enabled, so that the motor is continuously converted into reverse rotation from the forward rotation or is continuously converted into forward rotation from the reverse rotation.
In some embodiments, after triggering and executing the rotation protection procedure, the method further comprises:
Judging whether the current rotating speed after the speed reduction is equal to or greater than a preset rotating speed threshold value;
and if the current rotating speed after the speed reduction is smaller than the preset rotating speed threshold value, enabling a reverse rotating speed instruction.
In the embodiment of the disclosure, whether the current rotation speed after the speed reduction meets the rotation speed requirement of enabling the reverse rotation speed instruction is further judged, namely whether the current rotation speed after the speed reduction is smaller than a preset rotation speed threshold value or not; if the current rotating speed after the speed reduction is equal to or greater than a preset rotating speed threshold value, continuing the speed reduction until the current rotating speed after the speed reduction is less than the preset rotating speed threshold value, meeting the rotating speed requirement, and enabling the reverse rotating speed instruction to realize the conversion from the current unidirectional operation to the opposite operation under the condition of ensuring that the motor is not locked, thereby ensuring the continuous operation of the motor.
In some embodiments, taking the example that the reverse rotation speed command is received during the forward rotation of the motor, if the current rotation speed of the forward rotation of the motor is higher, it is required to first reduce the speed, for example, to a lower target rotation speed, or to reduce to 0, and then enable the reverse rotation speed command.
In some embodiments, taking the example that the forward rotation speed command is received during the reverse rotation of the motor, if the current rotation speed of the motor is higher, it is also necessary to first reduce the speed, for example, to a lower target rotation speed, or to reduce to 0, and then enable the forward rotation speed command.
In some embodiments, triggering and executing the rotation protection procedure further comprises:
and controlling the motor to slow down to stop.
In the embodiment of the disclosure, when a reverse rotating speed instruction is received in the unidirectional operation process of the motor, the motor is directly controlled to be decelerated to a stop, and the reverse rotating speed instruction is converted into an enabled reverse rotating speed instruction, so that the motor is prevented from being directly locked, the motor is enabled to continuously operate, and the clothes treatment equipment is enabled to continuously operate, so that user experience is improved.
In some embodiments, feedback control of the present rotational speed may be implemented based on the detected current.

As shown in fig. 2 and 3, Q3 corresponds to a unidirectional operation instruction issued by the normal operation main control board of the frequency converter, and corresponds to the motor in the normal unidirectional operation process; q2 corresponds to the reverse rotating speed instruction received by the frequency converter, namely an abnormal reversing command, and the frequency converter enters a speed reduction or even stopping state after receiving the reverse rotating speed instruction, namely braking is carried out to a range limited by a preset rotating speed range; q11 of the Q1 part corresponds to the frequency converter for judging the validity of the reverse rotation speed command, and enabling the reverse rotation speed command when the reverse rotation speed command is valid.
In an embodiment of the present disclosure, the operation process of the laundry treatment apparatus may include a main control board issuing a control instruction to a frequency converter, the frequency converter controlling the operation of a motor based on the received instruction; if a reverse rotation speed instruction is received in the running process of the forward rotation instruction, the frequency converter executes a rotation protection program to conduct abnormal protection so as to prevent the motor from being directly locked. Specifically, the rotation protection procedure may include: firstly, automatically reducing the speed and even stopping the machine; when the current speed is reduced to a rotation speed range limited by a preset rotation speed threshold value, a reverse rotation speed instruction is enabled, so that the motor is continuously converted from forward rotation to reverse rotation, namely, the motor continuously runs, and therefore, the operation of the clothes treatment equipment is uninterrupted, the operation continuity is good, and the user experience is improved.
