Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a control method for clothing processing equipment and clothing processing equipment. Background Technology

[0002] Washing machines include household washing machines and commercial washing machines. Household washing machines have a capacity of 6 kg or less and are used to meet the laundry needs of families. Commercial washing machines have a relatively larger capacity and are widely used in laundry facilities in garment factories, laundries, industrial and mining enterprises, schools, hotels, hospitals, and other similar establishments.

[0003] Whether it's a household or commercial washing machine, the door is generally located at the front of the machine body and is installed low. Children have limited ability to judge danger, and sometimes they may climb into the washing machine through the door; or pets may accidentally enter the washing machine. If users cannot notice in time that a child or pet has entered the washing machine, serious safety accidents may occur. Summary of the Invention

[0004] The purpose of this invention is to provide a control method and a garment processing device that can effectively prevent safety accidents caused by the garment processing device executing the garment processing procedure after a living being accidentally enters the garment processing device.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Control methods for garment handling equipment include:

[0007] S1. Check whether the door of the clothing processing equipment is locked; if yes, proceed to step S2; if no, control the clothing processing equipment not to execute the clothing processing program.

[0008] S2. Control the roller of the garment processing equipment to be stationary, and weigh the roller of the garment processing equipment;

[0009] Determine if the weighing result is normal; if yes, proceed to step S3; if no, control the garment processing equipment not to execute the garment processing procedure.

[0010] S3. Control the roller to rotate at a preset speed, and simultaneously detect the first and second operating parameters of the roller; determine whether the first and second operating parameters are both normal; if so, control the garment processing device to execute the garment processing program; if not, control the garment processing device not to execute the garment processing program.

[0011] Optionally, in step S3, the first operating parameter is the displacement signal of the roller, and the second operating parameter is the current signal of the drive component that drives the roller to rotate.

[0012] Optionally, in step S3, an accelerometer is used to acquire the displacement signal of the roller.

[0013] Optionally, there are multiple acceleration sensors, which are arranged on the roller using a preset method. The data acquired by the multiple acceleration sensors are processed using a first data processing method to obtain the first operating parameters.

[0014] Optionally, the garment processing equipment includes a control system, in which the control system controls the operation of the drive component and is able to acquire the current value flowing through the drive component in step S3.

[0015] Optionally, an alarm signal may be issued when the clothing processing device fails to execute the clothing processing procedure.

[0016] Optionally, step S1 includes:

[0017] S11. Detect whether the mechanical lock of the garment processing device is locked; if yes, proceed to step S2; if no, control the garment processing device not to execute the garment processing procedure.

[0018] Optionally, step S1 includes:

[0019] S11. Detect whether the mechanical lock of the garment processing device is locked; if yes, proceed to step S12; if no, control the garment processing device not to execute the garment processing procedure.

[0020] S12. Detect whether the electromagnetic lock of the garment processing device is locked; if yes, proceed to step S2; if no, control the garment processing device not to execute the garment processing program.

[0021] Optionally, in step S3, the preset speed is 20 r / min-100 r / min.

[0022] The garment processing equipment is controlled by the aforementioned garment processing equipment control method.

[0023] The beneficial effects of this invention are:

[0024] When the clothing processing equipment control method proposed in this invention controls the clothing processing equipment, in step S1, it first detects whether the door of the clothing processing equipment is locked. If the door of the clothing processing equipment is not locked, it means that the door of the clothing processing equipment is in an open state. At this time, a living being may enter the roller, so the clothing processing equipment is controlled not to execute the clothing processing program. If the door of the clothing processing equipment is locked, it is possible that a child has entered the roller and locked the door. Therefore, the clothing processing equipment cannot be controlled to execute the clothing processing program, and step S2 is executed.

[0025] In step S2, the control roller is kept stationary to prevent it from rotating and causing a safety accident if a living being accidentally entered inside. The roller is then weighed. If the weighing result is normal, meaning the roller's weight is less than its design weight at full load, there is still a possibility of a living being accidentally entered (e.g., the living being's weight is small). In this case, step S3 is executed to further determine if a living being has entered the roller. If the weighing result is abnormal, it indicates a high probability that a living being has entered the roller. In this case, the clothing processing equipment is controlled not to execute the clothing processing procedure.

[0026] When step S2 detects that the weighing result of the roller is normal, step S3 is executed to further detect whether a living being has mistakenly entered the roller. In step S3, the roller is controlled to rotate at a preset speed, and the first and second operating parameters of the roller are detected simultaneously. The normality of the first and second operating parameters is used to further determine whether a living being has mistakenly entered the roller. If both the first and second operating parameters are normal, it indicates that the roller is operating normally and no living being is interfering with its operation. At this time, the clothing processing device is controlled to execute the clothing processing program. If at least one of the first and second operating parameters is abnormal, it indicates that there is an abnormality in the operation of the roller, which may be caused by a living being mistakenly entering the roller. At this time, the clothing processing device is controlled not to execute the clothing processing program. Thus, through the detection in steps S2 and S3, by triple detection of the roller weight, the first operating parameter, and the second operating parameter of the roller, the safety accident caused by the clothing processing device executing the clothing processing program after a living being mistakenly enters the clothing processing device is effectively prevented.

[0027] The clothing processing device proposed in this invention uses the above-mentioned clothing processing equipment control method to control the clothing processing equipment, which fully avoids safety accidents caused by the clothing processing device executing the clothing processing program after a living person accidentally enters the clothing processing device.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0037] Example 1

[0038] See Figure 1 This embodiment provides a method for controlling a garment processing device.

[0039] Optionally, the garment handling equipment is a washing machine. Further options include a commercial washing machine or a household washing machine. A commercial washing machine is preferred.

[0040] Of course, in other embodiments, the garment processing device can also be a dryer.

[0041] Specifically, the control method for the garment processing equipment includes:

[0042] S1. Check if the door of the garment processing equipment is locked; if yes, proceed to step S2; if no, control the garment processing equipment not to execute the garment processing program.

[0043] S2. Control the roller of the garment processing equipment to be stationary and weigh the roller of the garment processing equipment;

[0044] Determine if the weighing result is normal; if yes, proceed to step S3; if no, control the garment processing equipment not to execute the garment processing procedure.

[0045] S3. Control the roller to rotate at a preset speed, and at the same time detect the first and second operating parameters of the roller; determine whether the first and second operating parameters are normal; if so, control the garment processing equipment to execute the garment processing program; if not, control the garment processing equipment not to execute the garment processing program.

[0046] Generally, garment handling devices include a door, which is used to open or close the roller. When the door is open, the user can put clothes into the roller; when the garment handling process needs to be performed, the door is switched to the closed position.

[0047] To ensure that the door remains stably closed, garment handling equipment typically includes a door locking mechanism to lock the door.

[0048] When using this garment processing equipment control method to control the garment processing equipment, in step S1, it is first detected whether the door of the garment processing equipment is locked. If the door of the garment processing equipment is not locked, it means that the door of the garment processing equipment is in an open state. At this time, a living being may enter the roller, so the garment processing equipment is controlled not to execute the garment processing program. If the door of the garment processing equipment is locked, it is possible that a child has entered the roller and locked the door. Therefore, the garment processing equipment cannot be controlled to execute the garment processing program, and step S2 is executed.

[0049] In step S2, the control roller is kept stationary, and then the roller is weighed to ensure the accuracy of the weighing result. If the weighing result is normal, that is, the weight of the roller is less than the design value of the roller when fully loaded, there is still a possibility that a living being has accidentally entered the roller (e.g., the weight of the living being is small), and step S3 is executed to further determine whether there is a living being inside the roller; if the weighing result is abnormal, it means that there is a high probability that a living being has accidentally entered the roller, and in this case, the clothing processing equipment is controlled not to execute the clothing processing program.

[0050] When step S2 detects that the weighing result of the roller is normal, step S3 is executed to further detect whether a living being has mistakenly entered the roller. In step S3, the roller is controlled to rotate at a preset speed, and the first and second operating parameters of the roller are detected simultaneously. The normality of the first and second operating parameters is used to further determine whether a living being has mistakenly entered the roller. If both the first and second operating parameters are normal, it indicates that the roller is operating normally and no living being is interfering with its operation. At this time, the clothing processing device is controlled to execute the clothing processing program. If at least one of the first and second operating parameters is abnormal, it indicates that there is an abnormality in the operation of the roller, which may be caused by a living being that has mistakenly entered the roller. At this time, the clothing processing device is controlled not to execute the clothing processing program.

[0051] Specifically, for smaller capacity garment processing devices, when a child or pet enters the drum, their weight usually exceeds the drum's rated weight capacity. In this case, the garment processing device will not execute the garment processing program and will issue an alarm. However, for larger capacity garment processing devices, when a child or pet enters the drum, their weight will not exceed the drum's rated weight capacity. In this case, step S3 will be executed to further detect whether a living being has mistakenly entered the drum.

[0052] The clothing processing equipment control method provided in this embodiment can effectively prevent safety accidents caused by children or pets accidentally entering the drum of the clothing processing device; that is, it can effectively detect whether children or pets have entered the drum of the clothing processing device; when it detects that a living being such as a child or pet has entered the drum, it can control the clothing processing equipment not to execute the clothing processing procedure, thereby avoiding safety accidents.

[0053] Furthermore, when the garment handling equipment fails to execute the garment handling procedure, an alarm signal is issued to remind the user to open the door and check inside the drum to see if any living beings have accidentally entered the drum.

[0054] Preferably, the alarm method is an audible alarm, such as emitting a buzzing sound or issuing a voice message saying "Please check the roller".

[0055] Specifically, commercial washing machines have larger drum capacities than household washing machines, allowing children or pets to hide among the large amounts of laundry inside. When using infrared detection to determine if a living being has entered the drum, there's a risk of the infrared detector missing a child hiding among the laundry, posing a safety hazard. However, the laundry handling equipment control method provided in this embodiment detects the presence of a living being inside the drum through steps S2 and S3. By triple-checking the drum weight, the first operating parameter, and the second operating parameter, the method effectively detects any such presence, preventing safety accidents during the operation of the commercial washing machine.

[0056] Optionally, in step S3, the preset speed is 20 r / min-100 r / min. 20 r / min-100 r / min is a relatively low rotational speed, which can accurately obtain the first and second operating parameters of the drum, and can also avoid harming any living organisms that accidentally enter the drum.

[0057] For example, in step S3, the preset speed is 20 r / min, 30 r / min, 40 r / min, 50 r / min, 60 r / min, 70 r / min, 80 r / min, 90 r / min, or 100 r / min. Of course, in other embodiments, the preset speed can also be set to other values, as needed, as long as it does not cause harm to any living organisms that accidentally enter the drum.

[0058] Optionally, in step S3, the time for which the roller rotates at a preset speed is set as a preset time, which is 5s-10s. This ensures accurate acquisition of the first and second operating parameters of the roller while preventing harm to any living organisms that accidentally enter the roller. For example, the preset time can be 5s, 6s, 7s, 8s, 9s, or 10s.

[0059] Of course, in other embodiments, the preset time can also be set to other values ​​as needed.

[0060] Example 2

[0061] This embodiment provides a method for controlling a garment processing device.

[0062] Specifically, the control method for the garment processing equipment includes:

[0063] S1. Check if the door of the garment processing equipment is locked; if yes, proceed to step S2; if no, control the garment processing equipment not to execute the garment processing program.

[0064] S2. Control the roller of the garment processing equipment to be stationary and weigh the roller of the garment processing equipment;

[0065] Determine if the weighing result is normal; if yes, proceed to step S3; if no, control the garment processing equipment not to execute the garment processing procedure.

[0066] S3. Control the roller to rotate at a preset speed, and at the same time detect the first and second operating parameters of the roller; determine whether the first and second operating parameters are normal; if so, control the garment processing equipment to execute the garment processing program; if not, control the garment processing equipment not to execute the garment processing program.

[0067] Generally, garment handling devices include a door, which is used to open or close the roller. When the door is open, the user can put clothes into the roller; when the garment handling process needs to be performed, the door is switched to the closed position.

[0068] To ensure that the door remains stably closed, garment handling equipment typically includes a door locking mechanism to lock the door.

[0069] When using this garment processing equipment control method to control the garment processing equipment, in step S1, it is first detected whether the door of the garment processing equipment is locked. If the door of the garment processing equipment is not locked, it means that the door of the garment processing equipment is in an open state. At this time, a living being may enter the roller, so the garment processing equipment is controlled not to execute the garment processing program. If the door of the garment processing equipment is locked, it is possible that a child has entered the roller and locked the door. Therefore, the garment processing equipment cannot be controlled to execute the garment processing program, and step S2 is executed.

[0070] In step S2, the control roller is kept stationary, and then the roller is weighed to ensure the accuracy of the weighing result. If the weighing result is normal, that is, the weight of the roller is less than the design value of the roller when fully loaded, there is still a possibility that a living being has accidentally entered the roller (e.g., the weight of the living being is small), and step S3 is executed to further determine whether there is a living being inside the roller; if the weighing result is abnormal, it means that there is a high probability that a living being has accidentally entered the roller, and in this case, the clothing processing equipment is controlled not to execute the clothing processing program.

[0071] When step S2 detects that the weighing result of the roller is normal, step S3 is executed to further detect whether a living being has mistakenly entered the roller. In step S3, the roller is controlled to rotate at a preset speed, and the first and second operating parameters of the roller are detected simultaneously. The normality of the first and second operating parameters is used to further determine whether a living being has mistakenly entered the roller. If both the first and second operating parameters are normal, it indicates that the roller is operating normally and no living being is interfering with its operation. At this time, the clothing processing device is controlled to execute the clothing processing program. If at least one of the first and second operating parameters is abnormal, it indicates that there is an abnormality in the operation of the roller, which may be caused by a living being that has mistakenly entered the roller. At this time, the clothing processing device is controlled not to execute the clothing processing program.

[0072] The clothing processing equipment control method provided in this embodiment can effectively prevent safety accidents caused by children or pets accidentally entering the drum of the clothing processing device; that is, it can effectively detect whether children or pets have entered the drum of the clothing processing device; when it detects that a living being such as a child or pet has entered the drum, it can control the clothing processing equipment not to execute the clothing processing procedure, thereby avoiding safety accidents.

[0073] Furthermore, while controlling the garment handling equipment not to execute the garment handling procedure, the garment handling device is also controlled to sound an alarm to remind the user to open the door and check inside the drum to see if any living beings have accidentally entered the drum.

[0074] Specifically, in step S2, a gravity sensor is used to weigh the roller. The gravity sensor is set at its lowest position when the roller is stationary to accurately obtain the weight of the roller.

[0075] Specifically, see Figure 2 In this embodiment, in step S3, the first operating parameter is the displacement signal of the drum, and the second operating parameter is the current signal of the driving component that drives the drum to rotate.

[0076] Furthermore, the driving component that drives the drum to rotate is a motor.

[0077] That is, in step S3, the roller is controlled to rotate at a preset speed, and the displacement signal of the roller and the current signal of the drive component that drives the roller to rotate are detected; it is determined whether the displacement signal of the roller and the current signal of the drive component that drives the roller to rotate are both normal; if so, the garment processing equipment is controlled to execute the garment processing program; if not, the garment processing equipment is controlled not to execute the garment processing program.

[0078] In step S2, after weighing the roller and finding no abnormalities, step S3 is executed.

[0079] In step S3, the drum rotates at a preset speed. If there is a living organism inside the drum, the drum will definitely experience abnormal and large-amplitude shaking, and the displacement signal of the drum will be abnormal. At the same time, due to the large-amplitude shaking of the drum, the drum will become eccentric. After the drum becomes eccentric, the drive component that drives the drum to rotate will emit an abnormal current, that is, the current signal of the drive component that drives the drum to rotate will be abnormal.

[0080] Specifically, in step S3, an accelerometer is used to acquire the displacement signal of the roller.

[0081] Furthermore, there are multiple acceleration sensors, which are arranged on the roller using a preset method. The data acquired by the multiple acceleration sensors are processed using a first data processing method to obtain the first operating parameters.

[0082] Optionally, the preset arrangement method is as follows: multiple acceleration sensors are arranged at intervals along the circumference of the roller on the outer surface of the roller. More optionally, four acceleration sensors are arranged at intervals along the circumference of the roller on the outer surface of the roller, with the central angle between two adjacent acceleration sensors being 90°.

[0083] Optionally, the preset arrangement method can also be: accelerometers are arranged at both the bottom and sides of the drum; for example, two accelerometers are symmetrically arranged on opposite sides of the drum, and two accelerometers are arranged radially at the bottom of the drum.

[0084] Of course, in other embodiments, the multiple acceleration sensors can also be arranged in other ways.

[0085] Optionally, the first data processing method is to obtain the average value of the data acquired by multiple acceleration sensors.

[0086] Alternatively, the first data processing method may further be: after removing the maximum and minimum values ​​of the data acquired by multiple acceleration sensors, take the average value of the remaining data.

[0087] The garment processing equipment includes a control system. Further, the first data processing method can also be: the actual displacement signal acquired by the accelerometer is processed by the control system to obtain acceleration and angular velocity; if both the acceleration and angular velocity values ​​are normal, the displacement signal of the roller is determined to be normal; otherwise, the displacement signal of the roller is determined to be abnormal.

[0088] Specifically, in the control system, the chip algorithm calculates displacement signal data that can be recognized by the overall system software. This acquired displacement signal data is then transmitted to the control system for identification. If the displacement signal data exceeds the system's set value, it is considered an abnormal signal. It's understandable that if a living organism enters the drum, the drum will inevitably sink suddenly. The drum will cause the accelerometer to move synchronously, and both will have downward displacement, allowing the accelerometer to acquire the actual displacement signal. The relationship between displacement and acceleration is a quadratic integral; acceleration is the second derivative of displacement with respect to time, meaning acceleration equals the rate of change of the rate of change of displacement with respect to time.

[0089] Furthermore, in step S3, the control system controls the drive component to operate and is able to acquire the current value flowing through the drive component.

[0090] In step S3, the control system is able to acquire the displacement signal of the roller; specifically, the control system is communicatively connected to the acceleration sensor.

[0091] Simultaneously, in step S2, the control system is also able to acquire the weight of the roller. Specifically, the control system is communicatively connected to the gravity sensor.

[0092] Example 3

[0093] This embodiment provides a method for controlling a garment processing device.

[0094] Specifically, the control method for the garment processing equipment includes:

[0095] S1. Check if the door of the garment processing equipment is locked; if yes, proceed to step S2; if no, control the garment processing equipment not to execute the garment processing program.

[0096] S2. Control the roller of the garment processing equipment to be stationary and weigh the roller of the garment processing equipment;

[0097] Determine if the weighing result is normal; if yes, proceed to step S3; if no, control the garment processing equipment not to execute the garment processing procedure.

[0098] S3. Control the roller to rotate at a preset speed, and at the same time detect the first and second operating parameters of the roller; determine whether the first and second operating parameters are normal; if so, control the garment processing equipment to execute the garment processing program; if not, control the garment processing equipment not to execute the garment processing program.

[0099] Generally, garment handling devices include a door, which is used to open or close the roller. When the door is open, the user can put clothes into the roller; when the garment handling process needs to be performed, the door is switched to the closed position.

[0100] To ensure that the door remains stably closed, garment handling equipment typically includes a door locking mechanism to lock the door.

[0101] When using this garment processing equipment control method to control the garment processing equipment, in step S1, it is first detected whether the door of the garment processing equipment is locked. If the door of the garment processing equipment is not locked, it means that the door of the garment processing equipment is in an open state. At this time, a living being may enter the roller, so the garment processing equipment is controlled not to execute the garment processing program. If the door of the garment processing equipment is locked, it is possible that a child has entered the roller and locked the door. Therefore, the garment processing equipment cannot be controlled to execute the garment processing program, and step S2 is executed.

[0102] In step S2, the control roller is kept stationary, and then the roller is weighed to ensure the accuracy of the weighing result. If the weighing result is normal, that is, the weight of the roller is less than the design value of the roller when fully loaded, there is still a possibility that a living being has accidentally entered the roller (e.g., the weight of the living being is small), and step S3 is executed to further determine whether there is a living being inside the roller; if the weighing result is abnormal, it means that there is a high probability that a living being has accidentally entered the roller, and in this case, the clothing processing equipment is controlled not to execute the clothing processing program.

[0103] When step S2 detects that the weighing result of the roller is normal, step S3 is executed to further detect whether a living being has mistakenly entered the roller. In step S3, the roller is controlled to rotate at a preset speed, and the first and second operating parameters of the roller are detected simultaneously. The normality of the first and second operating parameters is used to further determine whether a living being has mistakenly entered the roller. If both the first and second operating parameters are normal, it indicates that the roller is operating normally and no living being is interfering with its operation. At this time, the clothing processing device is controlled to execute the clothing processing program. If at least one of the first and second operating parameters is abnormal, it indicates that there is an abnormality in the operation of the roller, which may be caused by a living being that has mistakenly entered the roller. At this time, the clothing processing device is controlled not to execute the clothing processing program.

[0104] Specifically, for smaller capacity garment processing devices, when a child or pet enters the drum, their weight usually exceeds the drum's rated weight capacity. In this case, the garment processing device will not execute the garment processing program and will issue an alarm. However, for larger capacity garment processing devices, when a child or pet enters the drum, their weight will not exceed the drum's rated weight capacity. In this case, step S3 will be executed to further detect whether a living being has mistakenly entered the drum.

[0105] The clothing processing equipment control method provided in this embodiment can effectively prevent safety accidents caused by children or pets accidentally entering the drum of the clothing processing device; that is, it can effectively detect whether children or pets have entered the drum of the clothing processing device; when it detects that a living being such as a child or pet has entered the drum, it can control the clothing processing equipment not to execute the clothing processing procedure, thereby avoiding safety accidents.

[0106] Furthermore, when the garment handling equipment fails to execute the garment handling procedure, an alarm signal is issued to remind the user to open the door and check inside the drum to see if any living beings have accidentally entered the drum.

[0107] Preferably, the alarm method is an audible alarm, such as emitting a buzzing sound or issuing a voice message saying "Please check the roller".

[0108] Specifically, see Figure 3 Step S1 includes:

[0109] S11. Check whether the mechanical lock of the garment processing equipment is locked; if yes, proceed to step S2; if no, control the garment processing equipment not to execute the garment processing procedure.

[0110] It is understandable that some garment processing equipment has only mechanical locks on its doors, meaning that the door locking components only include mechanical locks. Therefore, in step S1, it is sufficient to check whether the mechanical lock of the garment processing equipment is locked.

[0111] The mechanical lock is in the locked state, indicating that the door is in a stable closed state.

[0112] In this embodiment, in step S3, the first operating parameter is the displacement signal of the drum, and the second operating parameter is the current signal of the driving component that drives the drum to rotate.

[0113] Furthermore, the driving component that drives the drum to rotate is a motor.

[0114] That is, in step S3, the roller is controlled to rotate at a preset speed, and the displacement signal of the roller and the current signal of the drive component that drives the roller to rotate are detected; it is determined whether the displacement signal of the roller and the current signal of the drive component that drives the roller to rotate are both normal; if so, the garment processing equipment is controlled to execute the garment processing program; if not, the garment processing equipment is controlled not to execute the garment processing program.

[0115] In step S2, after weighing the roller and finding no abnormalities, step S3 is executed.

[0116] In step S3, the drum rotates at a preset speed. If there is a living organism inside the drum, the drum will definitely experience abnormal and large-amplitude shaking, and the displacement signal of the drum will be abnormal. At the same time, due to the large-amplitude shaking of the drum, the drum will become eccentric. After the drum becomes eccentric, the drive component that drives the drum to rotate will emit an abnormal current, that is, the current signal of the drive component that drives the drum to rotate will be abnormal.

[0117] Specifically, in step S3, an accelerometer is used to acquire the displacement signal of the roller.

[0118] Furthermore, there are multiple acceleration sensors, which are arranged on the roller using a preset method. The data acquired by the multiple acceleration sensors are processed using a first data processing method to obtain the first operating parameters.

[0119] Optionally, the preset arrangement method is as follows: multiple acceleration sensors are arranged at intervals along the circumference of the roller on the outer surface of the roller. More optionally, four acceleration sensors are arranged at intervals along the circumference of the roller on the outer surface of the roller, with the central angle between two adjacent acceleration sensors being 90°.

[0120] Optionally, the preset arrangement method can also be: accelerometers are arranged at both the bottom and sides of the drum; for example, two accelerometers are symmetrically arranged on opposite sides of the drum, and two accelerometers are arranged radially at the bottom of the drum.

[0121] Of course, in other embodiments, the multiple acceleration sensors can also be arranged in other ways.

[0122] Optionally, the first data processing method is to obtain the average value of the data acquired by multiple acceleration sensors.

[0123] Alternatively, the first data processing method may further be: after removing the maximum and minimum values ​​of the data acquired by multiple acceleration sensors, take the average value of the remaining data.

[0124] The garment processing equipment includes a control system. Further, the first data processing method can also be: the actual displacement signal acquired by the accelerometer is processed by the control system to obtain acceleration and angular velocity; if both the acceleration and angular velocity values ​​are normal, the displacement signal of the roller is determined to be normal; otherwise, the displacement signal of the roller is determined to be abnormal.

[0125] Specifically, in the control system, the chip algorithm calculates displacement signal data that can be recognized by the overall system software. This acquired displacement signal data is then transmitted to the control system for identification. If the displacement signal data exceeds the system's set value, it is considered an abnormal signal. It's understandable that if a living organism enters the drum, the drum will inevitably sink suddenly. The drum will cause the accelerometer to move synchronously, and both will have downward displacement, resulting in the actual displacement signal acquired by the accelerometer. The relationship between displacement and acceleration is a quadratic integral; acceleration is the second derivative of displacement with respect to time, meaning acceleration equals the rate of change of the rate of change of displacement with respect to time.

[0126] Furthermore, in step S3, the control system controls the drive component to operate and is able to acquire the current value flowing through the drive component.

[0127] In step S3, the control system is able to acquire the displacement signal of the roller; specifically, the control system is communicatively connected to the acceleration sensor.

[0128] Simultaneously, in step S2, the control system is also able to acquire the weight of the roller. Specifically, the control system is communicatively connected to the gravity sensor.

[0129] Example 4

[0130] This embodiment provides a method for controlling a garment processing device.

[0131] Specifically, the control method for the garment processing equipment includes:

[0132] S1. Check if the door of the garment processing equipment is locked; if yes, proceed to step S2; if no, control the garment processing equipment not to execute the garment processing program.

[0133] S2. Control the roller of the garment processing equipment to be stationary and weigh the roller of the garment processing equipment;

[0134] Determine if the weighing result is normal; if yes, proceed to step S3; if no, control the garment processing equipment not to execute the garment processing procedure.

[0135] S3. Control the roller to rotate at a preset speed, and at the same time detect the first and second operating parameters of the roller; determine whether the first and second operating parameters are normal; if so, control the garment processing equipment to execute the garment processing program; if not, control the garment processing equipment not to execute the garment processing program.

[0136] Generally, garment handling devices include a door, which is used to open or close the roller. When the door is open, the user can put clothes into the roller; when the garment handling process needs to be performed, the door is switched to the closed position.

[0137] To ensure that the door remains stably closed, garment handling equipment typically includes a door locking mechanism to lock the door.

[0138] When using this garment processing equipment control method to control the garment processing equipment, in step S1, it is first detected whether the door of the garment processing equipment is locked. If the door of the garment processing equipment is not locked, it means that the door of the garment processing equipment is in an open state. At this time, a living being may enter the roller, so the garment processing equipment is controlled not to execute the garment processing program. If the door of the garment processing equipment is locked, it is possible that a child has entered the roller and locked the door. Therefore, the garment processing equipment cannot be controlled to execute the garment processing program, and step S2 is executed.

[0139] In step S2, the control roller is kept stationary, and then the roller is weighed to ensure the accuracy of the weighing result. If the weighing result is normal, that is, the weight of the roller is less than the design value of the roller when fully loaded, there is still a possibility that a living being has accidentally entered the roller (e.g., the weight of the living being is small), and step S3 is executed to further determine whether there is a living being inside the roller; if the weighing result is abnormal, it means that there is a high probability that a living being has accidentally entered the roller, and in this case, the clothing processing equipment is controlled not to execute the clothing processing program.

[0140] When step S2 detects that the weighing result of the roller is normal, step S3 is executed to further detect whether a living being has mistakenly entered the roller. In step S3, the roller is controlled to rotate at a preset speed, and the first and second operating parameters of the roller are detected simultaneously. The normality of the first and second operating parameters is used to further determine whether a living being has mistakenly entered the roller. If both the first and second operating parameters are normal, it indicates that the roller is operating normally and no living being is interfering with its operation. At this time, the clothing processing device is controlled to execute the clothing processing program. If at least one of the first and second operating parameters is abnormal, it indicates that there is an abnormality in the operation of the roller, which may be caused by a living being that has mistakenly entered the roller. At this time, the clothing processing device is controlled not to execute the clothing processing program.

[0141] Specifically, for smaller capacity garment processing devices, when a child or pet enters the drum, their weight usually exceeds the drum's rated weight capacity. In this case, the garment processing device will not execute the garment processing program and will issue an alarm. However, for larger capacity garment processing devices, when a child or pet enters the drum, their weight will not exceed the drum's rated weight capacity. In this case, step S3 will be executed to further detect whether a living being has mistakenly entered the drum.

[0142] The clothing processing equipment control method provided in this embodiment can effectively prevent safety accidents caused by children or pets accidentally entering the drum of the clothing processing device; that is, it can effectively detect whether children or pets have entered the drum of the clothing processing device; when it detects that a living being such as a child or pet has entered the drum, it can control the clothing processing equipment not to execute the clothing processing procedure, thereby avoiding safety accidents.

[0143] Furthermore, when the garment handling equipment fails to execute the garment handling procedure, an alarm signal is issued to remind the user to open the door and check inside the drum to see if any living beings have accidentally entered the drum.

[0144] Preferably, the alarm method is an audible alarm, such as emitting a buzzing sound or issuing a voice message saying "Please check the roller".

[0145] Specifically, see Figure 4 In this embodiment, step S1 includes:

[0146] S11. Check whether the mechanical lock of the garment processing equipment is locked; if yes, proceed to step S12; if no, control the garment processing equipment not to execute the garment processing program.

[0147] S12. Check whether the electromagnetic lock of the garment processing equipment is locked; if yes, proceed to step S2; if no, control the garment processing equipment not to execute the garment processing program.

[0148] It is understandable that some garment processing equipment has mechanical locks and electromagnetic locks on its doors, that is, the door locking components include mechanical locks and electromagnetic locks. Therefore, in step S1, it is detected whether the mechanical locks and electromagnetic locks of the garment processing equipment have been locked.

[0149] The mechanical lock is in the locked state, indicating that the door is in a stable closed state.

[0150] When the electromagnetic lock is locked, the user cannot open the door from the outside. Understandably, when an alarm is triggered, the electromagnetic lock is unlocked so that the user can open the door and check for any living beings inside the rollers.

[0151] In this embodiment, in step S3, the first operating parameter is the displacement signal of the drum, and the second operating parameter is the current signal of the driving component that drives the drum to rotate.

[0152] Furthermore, the driving component that drives the drum to rotate is a motor.

[0153] That is, in step S3, the roller is controlled to rotate at a preset speed, and the displacement signal of the roller and the current signal of the drive component that drives the roller to rotate are detected; it is determined whether the displacement signal of the roller and the current signal of the drive component that drives the roller to rotate are both normal; if so, the garment processing equipment is controlled to execute the garment processing program; if not, the garment processing equipment is controlled not to execute the garment processing program.

[0154] In step S2, after weighing the roller and finding no abnormalities, step S3 is executed.

[0155] In step S3, the drum rotates at a preset speed. If there is a living organism inside the drum, the drum will definitely experience abnormal and large-amplitude shaking, and the displacement signal of the drum will be abnormal. At the same time, due to the large-amplitude shaking of the drum, the drum will become eccentric. After the drum becomes eccentric, the drive component that drives the drum to rotate will emit an abnormal current, that is, the current signal of the drive component that drives the drum to rotate will be abnormal.

[0156] Specifically, in step S3, an accelerometer is used to acquire the displacement signal of the roller.

[0157] Furthermore, there are multiple acceleration sensors, which are arranged on the roller using a preset method. The data acquired by the multiple acceleration sensors are processed using a first data processing method to obtain the first operating parameters.

[0158] Optionally, the preset arrangement method is as follows: multiple acceleration sensors are arranged at intervals along the circumference of the roller on the outer surface of the roller. More optionally, four acceleration sensors are arranged at intervals along the circumference of the roller on the outer surface of the roller, with the central angle between two adjacent acceleration sensors being 90°.

[0159] Optionally, the preset arrangement method can also be: accelerometers are arranged at both the bottom and sides of the drum; for example, two accelerometers are symmetrically arranged on opposite sides of the drum, and two accelerometers are arranged radially at the bottom of the drum.

[0160] Of course, in other embodiments, the multiple acceleration sensors can also be arranged in other ways.

[0161] Optionally, the first data processing method is to obtain the average value of the data acquired by multiple acceleration sensors.

[0162] Alternatively, the first data processing method may further be: after removing the maximum and minimum values ​​of the data acquired by multiple acceleration sensors, take the average value of the remaining data.

[0163] The garment processing equipment includes a control system. Further, the first data processing method can also be: the actual displacement signal acquired by the accelerometer is processed by the control system to obtain acceleration and angular velocity; if both the acceleration and angular velocity values ​​are normal, the displacement signal of the roller is determined to be normal; otherwise, the displacement signal of the roller is determined to be abnormal.

[0164] Specifically, in the control system, the chip algorithm calculates displacement signal data that can be recognized by the overall system software. This acquired displacement signal data is then transmitted to the control system for identification. If the displacement signal data exceeds the system's set value, it is considered an abnormal signal.

[0165] Furthermore, in step S3, the control system controls the drive component to operate and is able to acquire the current value flowing through the drive component.

[0166] In step S3, the control system is able to acquire the displacement signal of the roller; specifically, the control system is communicatively connected to the acceleration sensor.

[0167] Simultaneously, in step S2, the control system is also able to acquire the weight of the roller. Specifically, the control system is communicatively connected to the gravity sensor.

[0168] Example 5

[0169] This embodiment provides a garment processing device, and the garment processing device control method of any one of embodiments one to four controls the operation of the garment processing device.

[0170] The garment processing equipment provided in this embodiment is controlled using the garment processing equipment control method described above.

[0171] When using this garment processing equipment control method to control the garment processing equipment, in step S1, it is first detected whether the door of the garment processing equipment is locked. If the door of the garment processing equipment is not locked, it means that the door of the garment processing equipment is in an open state. At this time, a living being may enter the roller, so the garment processing equipment is controlled not to execute the garment processing program. If the door of the garment processing equipment is locked, it is possible that a child has entered the roller and locked the door. Therefore, the garment processing equipment cannot be controlled to execute the garment processing program, and step S2 is executed.

[0172] In step S2, the roller is kept stationary to prevent it from rotating and causing a safety accident if a living being accidentally entered. The roller is then weighed. If the weighing result is normal, meaning the roller's weight is less than its design weight at full load, there is still a possibility of a living being accidentally entered (e.g., the living being's weight is small), and step S3 is executed. If the weighing result is abnormal, it indicates a high probability that a living being has entered the roller, and the garment processing equipment is prevented from executing the garment processing procedure.

[0173] When step S2 detects that the weighing result of the roller is normal, step S3 is executed to further detect whether a living being has mistakenly entered the roller. In step S3, the roller is controlled to rotate at a preset speed, and the first and second operating parameters of the roller are detected simultaneously. The normality of the first and second operating parameters is used to further determine whether a living being has mistakenly entered the roller. If both the first and second operating parameters are normal, it indicates that the roller is operating normally and no living being is interfering with its operation. At this time, the clothing processing device is controlled to execute the clothing processing program. If at least one of the first and second operating parameters is abnormal, it indicates that there is an abnormality in the operation of the roller, which may be caused by a living being that has mistakenly entered the roller. At this time, the clothing processing device is controlled not to execute the clothing processing program.
