AI Technical Summary
Existing washing machine cameras pose a risk of leaking user privacy when capturing clothing attribute information, thus affecting user experience.
The camera is positioned in the area where the housing and the door overlap. By detecting the movement parameters and status of the door, the camera can be selectively controlled to capture images of the clothing or issue a prompt message, thus avoiding shooting when the door is not fully open.
This effectively prevents the camera from capturing images of users when the shutter is not fully open, reducing the risk of privacy leaks and improving the user experience.

[0033] The preferred embodiments of the present application will be 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 application, and are not intended to limit the protection scope of the present application. For example, although the present application is described in combination with a drum washing machine, the technical solution of the present application is not limited thereto, and the control method can obviously be applied to other laundry treatment devices such as a pulsator washing machine, a dryer, a washer-dryer, a shoe washing machine, and a care machine, and such changes do not deviate from the principles and scope of the present application.
[0034] It should be noted that in the description of the present application, the terms "front", "upper", "circumferential" and other terms indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0035] Moreover, it needs to be explained that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0036] Based on the technical problems proposed in the background art, the present application provides a control method for a drum washing machine, the drum washing machine comprising a cabinet and a drum door pivotally connected with the cabinet, the cabinet is provided with a camera device for shooting images, and the camera device is located in the area where the cabinet and the drum door coincide. Relative to the technical solution of setting the camera on the front panel of the cabinet of the drum washing machine in the prior art, the camera device is set in the area where the cabinet and the drum door coincide, when the drum door is in the closed state, the drum door can shield the camera device, even if the camera device is mistakenly started, it cannot shoot the image of the user, thereby avoiding the leakage of the privacy of the user, and further improving the use experience of the user. Further, when the drum washing machine runs the clothes recognition mode, the motion parameter of the drum door is acquired, it is judged whether the motion parameter meets the preset condition, according to the judgment result of whether the motion parameter meets the preset condition, the camera device is selectively controlled to shoot the clothes image or to issue a prompt information, only when the motion parameter meets the preset condition, the camera device is controlled to shoot the clothes image, avoiding the camera device continuously performing the shooting operation, thereby reducing the probability of the camera device shooting the image of the user, which can avoid the leakage of the privacy of the user, and further improve the use experience of the user.
[0037] Firstly, referring to Figure 1 and Figure 2 , the drum washing machine of the present application is described. Among them, Figure 1 is the structure diagram of the drum washing machine of the present application; Figure 2 is the schematic diagram of the drum door of the present application in the closed state.
[0038] As shown in Figure 1 and Figure 2 , the drum washing machine of the present application comprises a cabinet 1 and a drum door 2, the front panel of the cabinet 1 (i.e. the panel shown in Figure 1 ) is provided with a clothes throwing opening 11 and a camera device 3, the camera device 3 is located above the clothes throwing opening 11 and in the area where the cabinet 1 and the drum door 2 coincide; the drum door 2 is pivotally connected with the front panel of the cabinet 1 through a pivot member 4, when the drum door 2 is pivoted to the open state, the camera device 3 is exposed to the environment (as shown in Figure 1 ), at this time, the camera device 3 can acquire the image of the clothes; when the drum door 2 is pivoted to the closed state, the drum door 2 can shield the camera device 3 (as shown inFigure 2 As shown, even if the camera device 3 is accidentally activated, it will not be able to capture images of the user, thus preventing the leakage of user privacy. Of course, the location of the camera device 3 is not limited to the locations listed above. For example, the camera device 3 can be arbitrarily set around the circumference of the clothing delivery port 11. No matter how the location of the camera device 3 is adjusted, as long as it is located in the area where the housing 1 and the door 2 overlap, so that the door 2 can block the camera device 3 when it is pivoted to the closed state, it is acceptable.
[0039] The imaging device 3 can be, but is not limited to, a camera, a video camera, or a camcorder. Preferably, the camera, video camera, or camcorder transmits the captured image data to the control mechanism of the drum washing machine via interfaces such as USB, serial port, DCMI, or MIPI. The control mechanism can then run the control method of this invention based on the received image data.
[0040] Among them, the pivoting component can be, but is not limited to, a pivot shaft, a door hinge, etc.
[0041] Preferably, the gate 2 is further provided with a detection component (not shown in the figure), which is used to detect the angular velocity, acceleration, and opening angle of the gate 2. The detection component may be, but is not limited to, a three-axis accelerometer, a six-axis accelerometer, or a gyroscope.
[0042] For example, taking a six-axis accelerometer as the detection component, at the installation position of the six-axis accelerometer, in the xoy plane (i.e., the horizontal plane), the linear acceleration 'a' in the x direction is... x and linear acceleration a in the y direction y The linear acceleration 'a' at the mounting position of the six-axis accelerometer on gate 2 (i.e., the acceleration of gate 2) is calculated. When gate 2 is opened from a stationary state, the acceleration detected by the six-axis accelerometer at the mounting position changes from 0 m / s². 2 When the gate 2 reaches a certain value (which is related to the opening speed), the acceleration a is 0 m / s² when the gate 2 comes to a standstill or moves at a constant speed. 2 Therefore, by using acceleration, it is possible to determine whether a classmate has been opened.
[0043] For example, taking a triaxial accelerometer as the detection component, during the pivoting opening of the gate 2 relative to the housing 1, the triaxial accelerometer continuously detects the acceleration detected by the triaxial accelerometer. The acceleration detected by the triaxial accelerometer increases from zero and gradually decreases to zero after reaching a certain value. At this time, the gate 2 completes the process from closed to open, and thus the opening angle of the gate 2 can be obtained.
[0044] For example, taking a gyroscope as the detection component, during the pivoting opening of the cylinder door 2 relative to the housing 1, the gyroscope continuously detects the angular velocity of the opening and closing of the cylinder door 2, thereby determining the opening angle of the cylinder door 2.
[0045] It should be noted that the detection principle and detection process of detecting the angular velocity, acceleration and opening angle of the detection drum door 2 by using the above-mentioned three-axis acceleration sensor, six-axis acceleration sensor or gyroscope and the like detection device all belong to the conventional technical means in the art, and will not be described here.
[0046] The following refers to Figure 3 The control method for a drum washing machine of the present application is described. Among them, Figure 3 is the main flow of the control method of the present application Figure 1 .
[0047] As Figure 3 shown, the control method for a drum washing machine of the present application comprises the following steps:
[0048] S100, acquiring the motion parameters of the drum door when the drum washing machine is running the laundry identification mode;
[0049] S200, determining whether the motion parameters meet the preset condition;
[0050] S300, selectively controlling the camera to shoot the image of the laundry or issuing a prompt information according to the determination result of whether the motion parameters meet the preset condition.
[0051] Among them, the motion parameters include angular velocity and acceleration. Preferably, the angular velocity can be the angle of the drum door turned in a unit time; the acceleration can be the rotational acceleration of the drum door moving in a circular motion around the pivot member.
[0052] Correspondingly, the preset condition includes the following two conditions:
[0053] Condition 11: the angular velocity is greater than the preset angular velocity;
[0054] Condition 12: the acceleration is greater than the preset acceleration.
[0055] In step S100, the angular velocity and acceleration of the drum door can be detected by a three-axis acceleration sensor, a six-axis acceleration sensor or a gyroscope and the like detection member. No matter what kind of detection member is adopted, the corresponding detection method should not constitute any limitation on the present application.
[0056] Of course, the motion parameters can also only include angular velocity or acceleration, and correspondingly, the preset condition can also only include angular velocity greater than preset angular velocity or acceleration greater than preset acceleration. The person skilled in the art can flexibly adjust and set the parameters included in the motion parameters and the judgment conditions included in the preset condition according to the actual use requirements.
[0057] The control method of the present application is further described below with the motion parameters including angular velocity and acceleration, and the preset conditions including angular velocity greater than preset angular velocity and acceleration greater than preset acceleration as examples.
[0058] Referring to Figures 4 to 7 The control method of selectively controlling the camera to take the image of the clothes or to send the prompt information according to the motion parameters of the door is described. Figure 4 is a flowchart of the control method of selectively controlling the camera to take the image of the clothes or to send the prompt information according to the motion parameters of the door of the present application. Figure 1 ; Figure 5 is a flowchart of the control method of selectively controlling the camera to take the image of the clothes or to send the prompt information according to the motion parameters of the door of the present application. Figure 2 ; Figure 6 is a flowchart of the control method of selectively controlling the camera to take the image of the clothes or to send the prompt information according to the motion parameters of the door of the present application. Figure 3 ; Figure 7 is a flowchart of the control method of selectively controlling the camera to take the image of the clothes or to send the prompt information according to the angle of the door opening of the present application.
[0059] As shown in Figure 4 , the step of "selectively controlling the camera to take the image of the clothes or to send the prompt information according to the judgment result of whether the motion parameters meet the preset conditions" in step S300 specifically includes:
[0060] S311, if the motion parameters meet the preset conditions, the angle of the door opening is obtained;
[0061] S312, it is judged whether the angle is greater than the preset angle;
[0062] S313, selectively controlling the camera to take the image of the clothes or to send the prompt information according to the judgment result of whether the angle is greater than the preset angle.
[0063] In steps S311 to S313, if the motion parameters meet the preset conditions, i.e. the angular velocity of the door is greater than the preset angular velocity, and the acceleration of the door is greater than the preset acceleration, for example, the preset angular velocity is 0 rad / s, the detected angular velocity is 5 rad / s, which is greater than the preset angular velocity, indicating that the door is being pivoted open; the preset acceleration is 0 m / s 2 , the detected angular velocity is 2 m / s 2 , which is greater than the preset acceleration, indicating that the door is being accelerated to open, and in summary, it can be determined that the door is being opened at a speed of 2 m / s 2The acceleration of the door is pivoted open, in order to accurately determine whether the door is opened to the preset position (i.e. not in the shooting range of the camera), the angle of the door opening is obtained, and according to the judgment result of whether the angle is greater than the preset angle, the camera is selectively controlled to shoot the clothes image or prompt information is sent, which avoids controlling the camera to shoot the clothes image when the door is not opened to the preset angle, thereby avoiding shooting the image of the user, and further avoiding leaking the privacy of the user.
[0064] As shown in Figure 5 , in step S300, the step of "selectively controlling the camera to shoot the clothes image or sending prompt information according to the judgment result of whether the motion parameter meets the preset condition" further includes:
[0065] S314, if the motion parameter does not meet the preset condition, controlling the camera to shoot the environment image;
[0066] S315, judging whether the environment image includes at least a part of the door; if yes, executing step S316; if no, executing step S317;
[0067] S316, sending prompt information of "opening the door";
[0068] S317, obtaining the angle of the door opening;
[0069] S318, judging whether the angle is greater than the preset angle;
[0070] S319, selectively controlling the camera to shoot the clothes image or sending prompt information according to the judgment result of whether the angle is greater than the preset angle.
[0071] In step S314, if the motion parameter does not meet the preset condition, for example, the angular velocity of the door is less than or equal to the preset angular velocity, assuming that the preset angular velocity is 0 rad / s, and the detected angular velocity is 0 rad / s, which is equal to the preset angular velocity, indicating that the door is stationary, which may have been opened to the preset position, or may not have been opened.
[0072] For another example, the acceleration of the door is less than or equal to the preset acceleration, assuming that the preset acceleration is 0 m / s 2 , and the detected angular velocity is 0 m / s 2 , which is equal to the preset acceleration, indicating that the door is stationary or the door is being opened at a constant speed.
[0073] Therefore, when at least one of the above two conditions is not met, the state of the drum door cannot be accurately determined, and whether the drum door is opened to the preset position cannot be determined. In order to further determine the current position of the drum door, the camera device is controlled to capture an environment image, and it is determined whether the environment image includes at least a part of the drum door, so as to determine the current position of the drum door.
[0074] In step S315, the environment image is sent to a database preset in the drum washing machine. The database compares the environment image with an image of the drum door, and further determines whether the environment image includes at least a part of the drum door.
[0075] In step S316, if the environment image includes at least a part of the drum door, for example, the environment image includes the entire drum door, it indicates that the drum door is still in a closed state or the opening angle is very small; or the environment image includes a part of the drum door, it indicates that the drum door has been opened but has not been opened to the preset position, and the picture of the drum door can still be captured. If the image of the clothes is obtained at this time, the drum door will also exist in the picture, which will interfere with the acquisition of the material, color, category and other attribute information of the clothes. In order to improve the accuracy of the acquisition of the attribute information of the clothes, a prompt information of "opening the drum door" is sent to prompt the user to open the drum door, and after the prompt information of "opening the drum door" is sent, the step S100 is returned.
[0076] Further, in the process of opening the drum door, the user can manually open the drum door, or can open the drum door through the control of the power device. Those skilled in the art can flexibly adjust and set the way of opening the drum door according to the specific product structure or market demand, and the present application does not make any limitation on this.
[0077] Further, the prompt information of "opening the drum door" can be sent in the form of voice, light, sound, picture, etc.
[0078] In steps S317 to S319, if the environment image does not include the drum door, it indicates that the drum door has been opened to the outside of the shooting range of the camera device. In order to ensure that the drum door is opened to the preset position, the opening angle of the drum door is obtained, and according to the judgment result of whether the angle is greater than the preset angle, the camera device is selectively controlled to capture the clothes image or send a prompt information, which avoids controlling the camera device to capture the clothes image when the drum door is not opened to the preset angle, thereby avoiding capturing the image of the user, and further avoiding leaking the privacy of the user.
[0079] Preferably, in step S317, the angle of the drum door can be detected in real time by a triaxial acceleration sensor, a six-axis acceleration sensor, or a gyroscope, etc. detection component, so as to timely control the camera to shoot the laundry image. Of course, the angle of the drum door can also be detected according to a first set time, for example, 1s, 2s, 3s or 4s, by a triaxial acceleration sensor, a six-axis acceleration sensor, or a gyroscope, etc. detection component, and those skilled in the art can flexibly adjust and set the first set time according to the actual detection needs.
[0080] As shown in Figure 6 steps S313 and S319, the step of "selectively controlling the camera to shoot the laundry image or issuing a prompt information according to the judgment result of whether the angle is greater than the preset angle" specifically includes:
[0081] S321, if the angle is greater than the preset angle, controlling the camera to shoot the laundry image;
[0082] S322, if the angle is less than or equal to the preset angle, counting the duration of the opening operation of the drum door;
[0083] S323, judging whether the duration is greater than or equal to a preset time; if yes, executing step S324; if no, executing step S325;
[0084] S324, issuing a prompt information of "abnormal drum door";
[0085] S325, acquiring the angle of the drum door opening again.
[0086] In step S321, if the angle is greater than the preset angle, for example, the preset angle is 150°, and the detected angle is 155°, which is greater than the preset angle, it indicates that the drum door has been opened to the preset position, at which the camera can shoot a clear and complete laundry image, and the drum door will not be shot, and will not interfere with the acquisition of the attribute information of the laundry such as material, color, and category, etc. Therefore, the camera is controlled to shoot the laundry image.
[0087] In step S322, if the angle is less than or equal to the preset angle, for example, the preset angle is 150°, and the detected angle is 100°, which is less than the preset angle, it indicates that the drum door has not been opened to the preset position, which may be that the opening time is too short, and there is not enough time to open the drum door to the preset position, or it may be that the drum door is abnormal and cannot be opened to the preset position. In order to accurately determine the reason why the drum door has not been opened to the preset position, the duration of the opening operation of the drum door is counted, so as to determine the reason why the drum door has not been opened to the preset position according to the duration.
[0088] In step S324, if the duration is greater than or equal to the preset time, for example, the preset time is 10s, and the counted time is 12s, which is greater than the preset time, it indicates that the door opening operation has been performed for 12s, which is enough to open the door to the preset position in the normal case of the door, but the door has not been opened to the preset position at this time, and the door can be considered to be abnormal, and a prompt information of "door abnormality" is sent to prompt the user that the door is abnormal, and the user can handle it in time.
[0089] The reason for the door abnormality can be that the drum washing machine is provided with an auxiliary door opening device, for example, a mechanical ejection device or a motor auxiliary door opening device, which can be considered to be abnormal due to the failure of the mechanical ejection device or the motor auxiliary door opening device, or that the drum washing machine is provided with a door opening and closing state detection member, which is opened but the door is not opened to the preset position, which can also be considered to be abnormal. Of course, the reason for the door abnormality can also be the failure of the pivoting member, which causes the door to be unable to pivot, etc., regardless of the reason, as long as the door failure can be determined.
[0090] Further, the prompt information of "door abnormality" can be sent in the form of voice, light, sound, picture, etc.
[0091] In step S325, if the duration is less than the preset time, for example, the preset time is 10s, and the counted time is 8s, which is less than the preset time, it indicates that only 8s of door opening operation has been performed, and the time for executing the door opening is short, and there is not enough time to open the door to the preset position, and the angle of the door opening is acquired again until the duration reaches the preset time or the angle is greater than the preset angle.
[0092] In the above process, only in the case that the angle of the door is greater than the preset angle, the shooting operation is performed, and in the case that the angle of the door is not greater than the preset angle, the shooting operation is not performed, which avoids the continuous shooting operation of the camera device and further reduces the probability of the camera device shooting the image of the user, thereby avoiding the leakage of the privacy of the user.
[0093] It should be noted that the above-mentioned angular velocity, preset angular velocity, acceleration, preset acceleration, angle and preset angle are only exemplary and are not limited, and the angular velocity, preset angular velocity, acceleration, preset acceleration, angle and preset angle can be flexibly adjusted and set according to the actual use requirements by those skilled in the art.
[0094] It should be further noted that in the above process, step S311 and step S314 have no sequence, are parallel, are only related to the judgment result of whether the motion parameter meets the preset condition, and the corresponding step can be executed according to different judgment results. Step S316 and step S317 have no sequence, are parallel, are only related to the judgment result of whether the environment image includes at least part of the door, and the corresponding step can be executed according to different judgment results. Step S321 and step S322 have no sequence, are parallel, are only related to the judgment result of whether the angle is greater than the preset angle, and the corresponding step can be executed according to different judgment results. Step S324 and step S325 have no sequence, are parallel, are only related to the judgment result of whether the duration is greater than or equal to the preset time, and the corresponding step can be executed according to different judgment results.
[0095] As shown in FIG. 4, in an alternative embodiment, in the case where the motion parameter does not meet the preset condition, step S300 includes the following steps: Figure 7
[0096] S331, controlling the camera to capture an environment image;
[0097] S332, judging whether the environment image includes at least part of the door; if yes, executing step S333; if no, executing step S334;
[0098] S333, issuing a prompt information of “open the door”;
[0099] S334, controlling the camera to capture a clothes image.
[0100] In step S331, in the case where the motion parameter does not meet the preset condition, that is, the state of the door cannot be accurately determined, and whether the door is opened to the preset position cannot be judged, the specific case is detailed in the case listed in step S314, which will not be repeated here. In order to further determine the current position of the door, the camera is controlled to capture an environment image, and it is judged whether the environment image includes at least part of the door, so as to determine the current position of the door.
[0101] In step S333, if the environment image includes at least part of the door, for example, the environment image includes the entire door, it indicates that the door is still in a closed state or the angle of opening is very small; or the environment image includes part of the door, it indicates that the door has been opened but has not been opened to the preset position, and the picture of the door can still be captured, if the image of the clothes is obtained at this time, the door will also exist in the picture, which will interfere with the acquisition of the attribute information of the clothes such as material, color and category. In order to improve the accuracy of the acquisition of the attribute information of the clothes, a prompt information of “open the door” is issued to prompt the user to open the door.
[0102] Further, in the process of opening the drum door, the user can manually open the drum door, or can open the drum door through the control of the power device, and those skilled in the art can flexibly adjust and set the opening mode of the drum door according to the specific product structure or market demand, and the present application does not make any limitation on this.
[0103] Further, the prompt information of "opening the drum door" can be in the form of voice, light, sound, picture, etc.
[0104] In step S334, if the environment image does not include the drum door, it means that the drum door has been opened out of the shooting range of the camera device, at this position, the camera device can shoot a clear and complete clothes image, and will not shoot the drum door, and will not interfere with the acquisition of the material, color, category and other attribute information of the clothes, then the camera device is controlled to shoot the clothes image.
[0105] It should be noted that in the above process, step S333 and step S334 have no sequence and are parallel, and are only related to the judgment result of whether the environment image includes at least part of the drum door, and the corresponding steps can be executed according to different judgment results.
[0106] The following refers to Figure 8 The control method of the present application is further introduced. Among them, Figure 8 is the complete flow chart of the control method of the present application.
[0107] As Figure 8 shown, before step S100, the control method further comprises:
[0108] S010, acquiring the opening and closing state of the drum door;
[0109] S020, judging whether the drum door is in an open state;
[0110] and selectively executing the operation of acquiring the motion parameter or issuing the prompt information according to the judgment result of whether the drum door is in an open state.
[0111] In step S010, a drum door opening and closing state detection member is arranged on the door lock of the drum washing machine, and the opening and closing state of the drum door is detected through the drum door opening and closing state detection member. Among them, the drum door opening and closing state detection member can be a door opening and closing sensor, a door magnetic opening and closing sensor, or a mechanical door opening and closing switch (i.e. when the drum door collides with the box body, the circuit of the mechanical door opening and closing switch is closed; when the drum door is separated from the box body, the circuit of the mechanical door opening and closing switch is opened), etc. No matter what kind of detection member is adopted, the corresponding detection method should not constitute any limitation on the present application.
[0112] With the above method, the user can be reminded to open the drum door in time in the case that the drum door is closed, so as to avoid the user waiting for a long time for the camera to perform the operation of capturing the image of the clothes; and the operation of acquiring the motion parameter is performed only in the case that the drum door is opened, so as to accurately determine whether to control the camera to capture the image of the clothes, and further avoid the leakage of the user's privacy.
[0113] With reference to the above Figure 8 , the step of "selectively performing the operation of acquiring the motion parameter or issuing the prompt information according to the determination result of whether the drum door is in the open state" specifically includes:
[0114] If the drum door is in the closed state, step S030 is performed;
[0115] If the drum door is in the open state, step S100 is performed;
[0116] S030, issuing the prompt information of "opening the drum door".
[0117] In step S030, if the drum door is in the closed state, it indicates that the drum door has not been opened, and the camera cannot capture the image of the clothes in the closed state, so the prompt information of "opening the drum door" is issued to prompt the user to open the drum door, and after the prompt information of "opening the drum door" is issued, step S100 is performed.
[0118] Further, the prompt information of "opening the drum door" can be issued in the form of voice, light, sound, picture, etc.
[0119] If the drum door is in the open state, it indicates that the drum door has been opened and is being rotated to the preset position, or is about to be rotated to the preset position, in order to accurately determine the current state of the drum door, the operation of acquiring the motion parameter of the drum door is performed.
[0120] Preferably, the operation of acquiring the motion parameter can be performed immediately after it is determined that the drum door is in the open state, or can be performed after it is determined that the drum door is in the open state and after a second set time, for example, 3s, 6s, 9s or 12s, the second set time can be flexibly adjusted and set by the person skilled in the art according to the actual detection requirement.
[0121] With reference to the above Figure 9 , another control method of the present application is introduced. Among them, Figure 9 is the main flow of the control method of the present application Figure 2 .
[0122] As shown in Figure 9 , the control method of the present application includes:
[0123] S400, acquire the opening and closing state of the drum door when the drum washing machine is running the laundry recognition mode;
[0124] S500, determine whether the drum door is in the open state;
[0125] S600, selectively control the camera to capture the laundry image or send the prompt information according to the determination result of whether the drum door is in the open state.
[0126] The method for acquiring the opening and closing state of the drum door can refer to the description in step S010, which will not be repeated here.
[0127] In step S600, if the drum door is in the open state, the motion parameter of the drum door is acquired, and selectively control the camera to capture the laundry image or send the prompt information according to the determination result of whether the motion parameter meets the preset condition. The specific method can refer to the description in step S300, which will not be repeated here.
[0128] If the drum door is in the closed state, the prompt information of "open the drum door" is sent. Preferably, the prompt information of "open the drum door" can be sent in the form of voice, light, sound, picture, etc.
[0129] By using the above control method, the camera is controlled to capture the laundry image only when the drum door is in the open state, which avoids the camera continuously performing the shooting operation, thereby reducing the probability of the camera capturing the image of the user, avoiding the leakage of the user's privacy, and further improving the user's use experience.
[0130] The following refers to Figure 10 , a possible control flow of the present application is introduced. Among them, Figure 10 is the logic diagram of the control method of the present application.
