[0045] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

The singular terms "one" and "the" may also include plural forms.

[0047] Clothes processing equipment is generally divided into two types according to the driving mode: direct drive and non-direct drive. The motor of non-direct drive clothes processing equipment is a brushless DC motor. During operation, the belt is tightly coupled with the pulley on the brushless DC motor, and the drum rotates or pauses under the drive of the brushless DC motor.

[0048] However, the belt and pulley are prone to aging after running for a period of time, or the initial installation is not in place, causing the belt to offset relative to the pulley, or the belt to fall or break, which will cause the drum to be unable to rotate. What is more serious is that when the drum is running at high speed, the belt may fall or break, making it impossible for the clothing processing equipment to rely on the brushless DC motor to slow down, posing a great safety hazard.

[0049] Therefore, in order to solve the above technical problems, the present invention provides the following technical solutions:

[0050] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a method for controlling a laundry processing device according to an embodiment of the present invention. Figure 1 As shown, the control method of the clothes processing device in the embodiment of the present invention mainly includes the following steps 101 to 104.

[0051] Step 101, during the operation of the brushless DC motor, collecting information of the monitored object through the data acquisition device;

[0052] In a specific implementation process, the clothing processing device is provided with a brushless DC motor and a data acquisition device, wherein the belt drive driven by the pulley of the brushless DC motor causes the drum to rotate or stop, and the monitored object can be set on the belt. During the operation of the brushless DC motor, the rotation speed of the brushless DC motor and the information of the monitored object are collected by the data acquisition device.

[0053] Specifically, the data acquisition device may include a first sensor for acquiring information of the monitored object. The first sensor may be a sensor capable of outputting detection light, such as an infrared sensor, and the monitored object includes a reflective film. In this way, after the first sensor outputs the detection light, it is reflected by the reflective film, or cannot be reflected by the reflective film, so that the sensor can use the reflected light signal of the reflective film detected as the information of the monitored object.

[0054] It should be noted that the above-mentioned data acquisition device collects information of the monitored object for exemplary purposes only, and this embodiment does not limit other acquisition methods. For example, the image of the monitored object can also be collected by an image acquisition device as the information of the monitored object, which will not be explained one by one here.

[0055] Step 102: Determine the transmission information of the belt based on the information of the monitored object;

[0056] In a specific implementation process, after obtaining the information of the monitored object, the information of the monitored object can be analyzed to obtain the transmission speed of the belt.

[0057] In some embodiments, the transmission speed of the belt can be calculated based on the receiving time interval between the reflective light signals of the two reflective films and the transmission distance of the reflective film when the reflective light signals of the two reflective films are received. For example, an infrared sensor can be provided, and the reflective light signal of the reflective film can be received once every rotation of the reflective film, so that the receiving time interval between the reflective light signals of the two reflective films to be calculated can be obtained based on the time of each reception of the reflective light signal of the reflective film, and the number of rotations between the reflective light signals of the two reflective films can be obtained based on the distance transmitted by one rotation, and the total transmission distance can be obtained, so that the transmission speed of the belt can be calculated.

[0058] It should be noted that the above-mentioned method of realizing the belt transmission speed according to the reflected light signal received from the reflective film is only an exemplary description, and the present embodiment is not limited thereto. For example, multiple infrared sensors can be arranged at intervals, and the time when each sensor receives the reflected light signal from the reflective film can be determined, and then the time interval is obtained, and the distance used for the speed to be calculated is obtained according to the spacing between the multiple sensors, thereby obtaining the transmission speed of the belt. No more examples are given here.

[0059] In a specific implementation process, after obtaining the information of the monitored object, the information of the monitored object can also be analyzed to obtain the position of the belt relative to the pulley.

[0060] Specifically, the coordinates of the monitored object may be acquired based on the information of the monitored object; and the position of the belt relative to the pulley may be determined according to the coordinates of the monitored object.

[0061] Here, an example is taken in which the monitored object is a reflective film and the information of the monitored object is a reflected light signal of the reflective film.

[0062] In a specific implementation process, after the reflective signal of the reflective film is detected in a continuous time, the coordinates of the reflective film in a set coordinate system can be obtained, and then the deviation angle of the monitored object relative to the pulley can be obtained based on the coordinates of the pulley in the coordinate system, and the position of the belt relative to the pulley can be further obtained based on the angle.

[0063] In a specific implementation process, the reflective film may be in the shape of thin strips, so that the reflective signal of the reflective film is relatively more, thereby more accurately obtaining the position of the reflective film relative to the pulley, and further accurately obtaining the position of the belt relative to the pulley.

[0064] Step 103: judging whether the belt is abnormal according to the transmission information of the belt;

[0065] In a specific implementation process, when the transmission information of the belt includes the transmission speed of the belt, Figure 2 The flowchart of the illustrated embodiment implements step 103 . Figure 2 yes Figure 1 A flowchart of an implementation method of step 103 in FIG.

[0066] Step 201, obtaining a required speed of the belt based on a transmission ratio between the brushless DC motor and the acquired rotation speed of the brushless DC motor;

[0067] In a specific implementation process, the required speed of the belt can be obtained based on the rotation speed of the brushless DC motor and the transmission ratio of the brushless DC motor. That is, since the transmission ratio of the brushless DC motor is fixed, after obtaining the rotation speed of the brushless DC motor, the required speed of the belt can be obtained to drive the roller to rotate or stop. The rotation speed of the brushless DC motor can be collected by a second sensor for collecting the rotation speed of the brushless DC motor included in the data collection device. The second sensor can be a speed sensor, which can be arranged on the brushless DC motor.

[0068] Step 202, calculating the speed difference between the transmission speed of the belt and the required speed of the belt;

[0069] Step 203, detecting whether the speed difference is within a preset error range, if so, executing step 204, if not, executing step 205;

[0070] Step 204: Detect that the transmission speed of the belt is normal;

[0071] If the speed difference is within the preset error range, it means that there may be no risk of aging or improper installation, falling off, breaking, etc., and the transmission speed of the belt is detected to be normal.

[0072] Step 205: Detect that the transmission speed of the belt is abnormal.

[0073] If the speed difference is outside the preset error range, it means that there may be risks of falling off or breaking due to aging or improper installation, thereby detecting that the transmission speed of the belt is abnormal.

[0074] In a specific implementation process, when the transmission information of the belt includes the position of the belt relative to the pulley, the position of the belt can be determined according to Figure 3 The flowchart of the illustrated embodiment implements step 103 . Figure 3 yes Figure 1 Flow chart of another implementation method of step 103 in FIG.

[0075] Step 301, determine whether the position of the belt relative to the pulley is outside the preset range; if so, execute step 302; if not, execute step 303;

[0076] Step 302: determine whether the belt is offset or falls off relative to the pulley;

[0077] In a specific implementation process, a preset range of the belt relative to the pulley can be preset. If the position of the belt relative to the pulley is outside the preset range, it can be determined that the belt is offset or falls off relative to the pulley.

[0078] Step 303: determine that the belt is not offset or fallen off relative to the pulley.

[0079] If the position of the belt relative to the pulley is within a preset range, it can be determined that the belt has not shifted or fallen off relative to the pulley.

[0080] Step 104: If it is determined that the belt is abnormal, control the clothing processing device to perform abnormal processing operations.

[0081] In a specific implementation process, if it is determined that the belt has an abnormality, the clothing processing device is controlled to perform an abnormality processing operation; if it is determined that the belt has no abnormality, the process returns to step 101.

[0082] In a specific implementation process, if the transmission speed of the belt is abnormal, the clothing processing device can be controlled to perform but not limited to the following abnormal processing operations: outputting a prompt message of abnormal belt speed, directly shutting down the machine. For example, the display screen or APP of the clothing processing device can be used to output, accompanied by a warning sound, to indicate whether the pulley is aging and loose, or is not installed properly.

[0083] In a specific implementation process, if the belt is offset or falls off relative to the pulley, the clothing processing device can be controlled to perform but not limited to the following abnormal processing operations: outputting a prompt message of the belt offset or falling off, directly performing a shutdown operation. For example, the display screen or APP of the clothing processing device can be output, accompanied by a warning sound, to indicate whether the pulley is aging and loose, or is not installed properly.

[0084] The control method of the clothing processing device of this embodiment is as follows: during the operation of the brushless DC motor, the rotation speed of the brushless DC motor and the information of the monitored object are collected by the data acquisition device; based on the information of the monitored object, the transmission information of the belt is determined; according to the transmission information of the belt, it is judged whether the belt is abnormal; if it is judged that the belt is abnormal, the clothing processing device is controlled to perform the operation of abnormal processing.

[0085] In a specific implementation process, if the clothes processing device can always execute the current program (the clothes processing device performs the operation of abnormal processing or the operation of the second abnormal processing is only to output prompt information, but the user does not control the clothes processing device, then the clothes processing device can always execute the current program, or the transmission speed of the belt is normal, and it is a disengaged and cheap pulley, and the clothes processing device can always execute the current program), if the clothes processing device mistakenly determines that the drum has stopped, it may cause the user to open the door and get injured. Therefore, the following steps may also be performed:

[0086] (1) if the clothes processing device has been executing the current program, obtaining the remaining time of the current program of the clothes processing device;

[0087] (2) when the remaining time reaches a preset threshold, detecting whether the current transmission speed of the belt meets the safety shutdown condition;

[0088] In a specific implementation process, when the remaining time reaches a preset threshold, if the belt can be controlled to decrease from the current transmission speed of the belt to 0 in a decreasing trend within the remaining time, it is detected that the current transmission speed of the belt meets the safety shutdown condition; if the transmission speed of the belt continues to be high during the remaining time, or the transmission speed of the belt is reduced to 0 before the end time of the current program, it is detected that the current transmission speed of the belt does not meet the safety shutdown condition.

[0089] In a specific implementation process, the preset threshold value may be but is not limited to 3 minutes. That is to say, 3 minutes before the end of the operation of the laundry treatment device, if the belt can be controlled to decrease from the current transmission speed of the belt to 0 in a decreasing trend within 3 minutes, it means that when the laundry treatment device ends its operation, the drum can also stop rolling, and the laundry treatment device can be safely shut down. On the contrary, if the transmission speed of the belt continues to be high within 3 minutes (the belt is aged and cannot be effectively decelerated), or it is reduced to 0 before the end time of the current program (the belt falls off, the belt is no longer rotating, but the drum is still rotating), it means that when the laundry treatment device ends its operation, the drum may not stop rolling, and the laundry treatment device is not safely shut down.

[0090] (3) if the current transmission speed of the belt meets the safety shutdown condition, when the clothing processing device stops, the door is automatically opened;

[0091] (4) If the current transmission speed of the belt does not meet the safety shutdown condition, when the clothing processing device is shut down, the door is prohibited from opening automatically, and the door is opened after receiving a manual door opening command.
