Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing, and in particular provides a control method for clothing processing equipment. Background Art

[0002] Clothes are made of a variety of materials, and the most suitable washing time and temperature for different materials are different. At the most suitable washing time and temperature, the washing effect of the clothes to be washed is better. When washing clothes in traditional washing machines, users usually need to manually select the appropriate washing program according to the material and type of the clothes to wash the clothes. The process is cumbersome and it is easy to select the wrong washing program, resulting in a bad user experience.

[0003] At present, some washing machines use cameras to obtain images of laundry, and use image recognition technology to accurately obtain the material of the laundry in the image, and then determine a specific washing program based on the material of the laundry. The washing program determined in this way can usually achieve better washing results.

[0004] There are many ways to obtain images of laundry through a camera. One possible way is to set a camera on the window mat, and after the laundry is placed in the washing tub, the camera is used to obtain images of the laundry in the washing tub. However, after the laundry is placed in the washing tub, the laundry is easy to fold and crumple, and the washing tub is easy to reflect light. Therefore, the recognition accuracy of the image of the laundry obtained by the camera is low, and the washing program determined based on the recognition result is not very accurate, which affects the user experience.

[0005] Another possible implementation is to set a camera on the front side of the washing machine body, and use the camera to collect images of the laundry in the user's hands. However, the camera set in this way can usually continuously collect images of the outside of the washing machine, and cannot accurately determine whether the user is holding the laundry passing by the washing machine or preparing to put the laundry in the hand into the washing machine. In addition, if the camera is not blocked, there may be a risk of leaking the user's privacy. If it is blocked, it is necessary to set an additional shielding plate or cover on the outside of the camera, which is complex in structure and easily affects the camera's viewing angle.

[0006] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0007] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the existing washing machine has an inadequate way of acquiring images of laundry, the present invention provides a control method for a laundry processing device, the laundry processing device comprising a body and a barrel door pivotally arranged on the body, a camera device being arranged on the barrel door or in an area where the body and the barrel door overlap, the camera device being used to acquire images of laundry, the control method comprising: when running a laundry recognition mode, acquiring an opening angle of the barrel door; judging the interval in which the angle is located; and based on the judgment result, selectively starting the camera device or adjusting the opening angle of the barrel door.

[0008] In the preferred technical solution of the above control method, the step of "selectively starting the camera device or adjusting the opening angle of the barrel door based on the judgment result" further includes: if the angle is greater than or equal to a first preset angle and less than or equal to a second preset angle, starting the camera device.

[0009] In the preferred technical solution of the above control method, the clothing processing equipment is provided with a power device, which is used to drive the barrel door to rotate, and the step of "selectively starting the camera device or adjusting the opening angle of the barrel door based on the judgment result" further includes: if the angle is less than a first preset angle, or the angle is greater than a second preset angle, controlling the power device to operate to adjust the opening angle of the barrel door.

[0010] In the preferred technical solution of the above-mentioned control method, the step of "controlling the operation of the power device to adjust the opening angle of the barrel door" further includes: if the angle is less than the first preset angle, controlling the operation of the power device to increase the opening angle of the barrel door; if the angle is greater than the second preset angle, controlling the operation of the power device to reduce the opening angle of the barrel door.

[0011] In the preferred technical scheme of the above-mentioned control method, the step of "controlling the power device to increase the opening angle of the barrel door" further includes: obtaining the rotation angle of the barrel door and the opening angle of the barrel door; judging the angle range of the rotation angle; if the rotation angle is within the first angle range, controlling the power device to stop running; otherwise, controlling the power device to continue running; wherein, the first angle range is determined based on the first preset angle, the second preset angle and the opening angle of the barrel door; and / or the step of "controlling the power device to reduce the opening angle of the barrel door" further includes: obtaining the rotation angle of the barrel door and the opening angle of the barrel door; judging the angle range of the rotation angle; if the rotation angle is within the second angle range, controlling the power device to stop running; otherwise, controlling the power device to continue running; wherein, the second angle range is determined based on the first preset angle, the second preset angle and the opening angle of the barrel door.

[0012] In the preferred technical solution of the above-mentioned control method, after the step of "controlling the operation of the power device to adjust the opening angle of the barrel door", the control method also includes: obtaining the opening angle of the barrel door; determining whether the angle is greater than or equal to a first preset angle and less than or equal to a second preset angle; if so, controlling the power device to stop running.

[0013] In the preferred technical solution of the above control method, after the step of "starting the camera device", the control method also includes: acquiring an image of the laundry to be washed; determining clothing information of the laundry based on the image; determining a clothing processing program based on the clothing information; and controlling the clothing processing device to run the clothing processing program.

[0014] In a preferred technical solution of the above control method, the control method further comprises: if the angle is zero, issuing a prompt message of "open the barrel door".

[0015] In a preferred technical solution of the above control method, at the same time as or after the step of "starting the camera device", the control method further includes: issuing a prompt message of "putting in clothes".

[0016] In the preferred technical solution of the above-mentioned control method, the clothing processing equipment also includes a clothing processing drum, and the camera device is configured to acquire an image inside the clothing processing drum during the operation of the clothing processing equipment. The control method also includes: acquiring an image inside the clothing processing drum during the operation of the clothing processing equipment; and determining clothing processing process information based on the image.

[0017] In a preferred technical solution of the present invention, the clothes processing device includes a body and a barrel door pivotally arranged on the body, and a camera device is arranged on the barrel door or in an area where the body and the barrel door overlap, and the image of the laundry can be obtained through the camera device. In this way, when the barrel door is closed, the camera device cannot collect images outside the clothes processing device, thereby effectively avoiding leakage of user privacy.

[0018] The control method of the present invention includes: when running the clothing recognition mode, obtaining the angle of the barrel door opening, judging the interval of the angle, and selectively starting the camera device or adjusting the angle of the barrel door opening based on the judgment result. Through such a control method, the camera device can be started or the opening angle of the barrel door can be adjusted according to the specific angle of the barrel door, so that the camera device can be started at a more appropriate time, and the image of the laundry obtained by the camera device will be clearer, and the clothes can be better identified based on the image, so as to obtain a better clothing treatment effect. At the same time, this also means that the camera device is not always working, so that the privacy of the user can be better avoided.

[0019] Furthermore, the step of "selectively starting the camera device or adjusting the opening angle of the barrel door based on the judgment result" further includes: if the angle is greater than or equal to the first preset angle and less than or equal to the second preset angle, starting the camera device. After starting the camera device, the image of the laundry can be obtained through the camera device. In other words, the camera device will only capture the image of the laundry when the opening angle of the barrel door is within the angle range between the first preset angle and the second preset angle, and can capture a clearer image. When the opening angle of the barrel door is outside the angle range, the camera device is not started, so as to better avoid leaking the user's privacy.

[0020] Furthermore, the laundry processing device is equipped with a power device, which is used to drive the barrel door to rotate, so that the opening angle of the barrel door can be adjusted by controlling the operation of the power device. The step of "selectively starting the camera device or adjusting the opening angle of the barrel door based on the judgment result" further includes controlling the power transposition operation to adjust the opening angle of the barrel door if the angle is less than the first preset angle or greater than the second preset angle. Through such a control method, when the opening angle of the barrel door is not within the angle range between the first preset angle and the second preset angle, the opening angle of the barrel door can be adjusted by the power device, so that the barrel door is rotated until the opening angle of the barrel door is within the angle range, so that the image of the laundry to be washed can be better obtained.

[0021] Furthermore, the step of "controlling the power device to adjust the opening angle of the barrel door" further includes: if the angle is less than the first preset angle, controlling the power device to increase the opening angle of the barrel door; if the angle is greater than the second preset angle, controlling the power device to decrease the opening angle of the barrel door. By such a control method, when the opening angle of the barrel door is relatively small, the shooting angle of the camera device is limited, and a clearer and more complete image of the laundry cannot be obtained, so it is necessary to increase the opening angle of the barrel door through the power device. When the opening angle of the barrel door is relatively large, there is a risk of leaking user privacy, and it is necessary to reduce the opening angle of the barrel door through the power device. By such a control method, the opening angle of the barrel door can be adjusted to within the angle range between the first preset angle and the second preset angle, so that the opening angle of the barrel door can be adjusted more accurately.

[0022] Furthermore, the step of "controlling the power device to increase the opening angle of the barrel door" further includes: obtaining the rotation angle of the barrel door and the opening angle of the barrel door, determining the angle range of the rotation angle, and if the rotation angle is within the first angle range, controlling the power device to stop running, otherwise, controlling the power device to continue running. The first angle range is determined based on the first preset angle, the second preset angle and the opening angle of the barrel door. In other words, if the rotation angle is within the first angle range, it means that the barrel door has been rotated to a suitable position, and the camera device can obtain a relatively complete and clear image of the laundry to be washed. At this time, the power device is controlled to stop running. If the rotation angle is outside the first angle range, it means that the barrel door has not been rotated to a suitable position. At this time, it is necessary to control the power device to continue running to adjust the opening angle of the barrel door.

[0023] Furthermore, the step of "controlling the power device to reduce the opening angle of the barrel door" further includes: obtaining the rotation angle of the barrel door and the opening angle of the barrel door, determining the angle range of the rotation angle, and if the rotation angle is within the second angle range, controlling the power device to stop running, otherwise, controlling the power device to continue running. The second angle range is determined based on the first preset angle, the second preset angle and the opening angle of the barrel door. In other words, if the rotation angle is within the second angle range, it means that the barrel door has been rotated to a suitable position, and the camera device can obtain a relatively complete and clear image of the laundry to be washed. At this time, the power device is controlled to stop running. If the rotation angle is outside the second angle range, it means that the barrel door has not been rotated to a suitable position. At this time, it is necessary to control the power device to continue running to adjust the opening angle of the barrel door.

[0024] Through such a control method, the operating timing and specific operating method of the power device can be controlled more accurately, and the opening angle of the barrel door can be controlled more accurately, and the opening angle of the barrel door can be better adjusted to between the first preset angle and the second preset angle.

[0025] Furthermore, after the step of "controlling the power device to adjust the opening angle of the barrel door", the control method of the present invention further includes: obtaining the opening angle of the barrel door, determining whether the angle is greater than or equal to the first preset angle and less than or equal to the second preset angle, and if so, controlling the power device to stop running. That is, in the process of adjusting the opening angle of the barrel door by the power device, the current opening angle of the barrel door is detected in real time. If the angle is greater than or equal to the first preset angle and less than or equal to the second preset angle, it means that the current opening angle of the barrel door is exactly within the angle range of the first preset angle and the second preset angle. In this case, the opening angle of the barrel door does not need to be increased or decreased, and the power device is controlled to stop running, and the camera device can be started, so that the opening angle of the barrel door can be controlled more accurately.

[0026] Furthermore, at the same time or after the step of "starting the camera device", the control method of the present invention further includes: acquiring an image of the laundry to be washed, determining the laundry information of the laundry based on the image, determining a laundry treatment program based on the laundry information, and controlling the laundry treatment device to run the laundry treatment program. Through such a control method, a suitable laundry treatment program can be determined specifically according to the laundry information of the laundry, so that the laundry can be better treated.

[0027] Furthermore, the control method of the present invention further includes: if the angle is zero, a prompt message of "open the tub door" is issued. If the opening angle of the tub door is zero, it means that the tub door is closed and not opened at all, and the user needs to process the laundry. At this time, it is necessary to remind the user to open the tub door. When the opening angle of the tub door is between the first preset angle and the second preset angle, the image of the laundry can be captured by the camera device.

[0028] Furthermore, after the step of "controlling the clothes processing device to run the clothes processing program", the control method of the present invention further includes: issuing a prompt message of "putting in clothes". Before controlling the clothes processing device to run, the prompt message of "putting in clothes" is issued to remind the user to put in clothes, thereby avoiding the occurrence of situations such as idling of the clothes processing device.

[0029] Furthermore, the clothing processing device also includes a clothing processing drum, which is used to hold clothes to be washed. The camera device is configured to be able to obtain images of the clothing processing drum during the operation of the clothing processing device. The control method of the present invention also includes: during the operation of the clothing processing device, obtaining images of the clothing processing drum, and determining clothing processing process information based on the images. For example, if the clothing processing device is a washing machine, the clothing processing process information may be information such as washing water and lint. Based on the clothing processing process information, the user can understand in detail the specific situation in the washing tub during the clothing processing process, which is more intuitive.

[0041] The preferred 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 scope of protection of the present invention. Although this embodiment is described by taking a drum washing machine as an example, it is also applicable to other types of clothing processing equipment such as a pulsator washing machine, a washer-dryer, and a dryer.

[0042] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do 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 limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0043] At present, the user experience is not good by manually selecting the washing program, and the camera setting method is not ideal for determining the material of the laundry and then determining the specific washing program through image recognition technology. For example, the image of the laundry in the washing tub is captured by the camera, but the image captured in this way is not clear enough and the recognition accuracy is low. For another example, the image of the laundry in the user's hand is captured by the camera. This method usually sets the camera on the outside of the washing machine, which is easy to collect wrong information (such as the user passing by with the clothes, etc.) and leak the user's privacy. The clothing processing device of the present invention can selectively start the camera device or adjust the opening angle of the barrel door according to the opening angle of the barrel door, so as to obtain a clear image of the laundry without leaking the user's privacy. Based on the image, the clothes can be better identified and a better clothing processing effect can be obtained.

[0044] First, refer to Figure 1 To illustrate the possible configuration of the laundry processing device of the present invention. Figure 1 It is a schematic structural diagram of a drum washing machine according to an embodiment of the present invention.

[0045] like Figure 1 As shown, the drum washing machine 1 includes a body 11 and a barrel door 12. A washing barrel is disposed in the body 11, and a clothes loading port 14 is formed in the body 11. The barrel door 12 is pivotally disposed at the front side of the body 11. When the barrel door 12 is pivotally opened relative to the body 11, the clothes loading port 14 is exposed to the environment, and the user can put the clothes to be washed into the washing barrel through the clothes loading port 14. When the barrel door 12 is pivotally closed relative to the body 11, the clothes loading port 14 can be blocked.

[0046] The upper part of the barrel door 12 is provided with a camera 13, which is used to obtain the image of the laundry to be washed. The camera 13 can be a camera, a still camera, a video camera, etc., as long as it can obtain the image of the laundry to be washed.

[0047] In this way, when the user needs to wash clothes, first the barrel door 12 is pivoted open relative to the machine body 11, and the user takes the laundry to be washed between the opened barrel door 12 and the machine body 11, and prepares to put the laundry in. At this time, the image of the laundry can be obtained through the camera device 13. During the laundry washing process or when there is no need to wash the clothes, the barrel door 12 is pivoted closed relative to the machine body 11. At this time, the camera device 13 cannot capture images outside the laundry processing device, thereby effectively avoiding the disclosure of the user's privacy. At the same time, when the barrel door 12 is closed, the camera device 13 can capture images inside the washing barrel. Naturally, during the operation of the drum washing machine 1, the camera device 13 can also capture images inside the washing barrel.

[0048] It should be noted that the laundry can be held by the user or placed in a laundry basket. Of course, it can also be placed in other locations, as long as the camera device can obtain the image of the laundry when the clothing recognition mode is running.

[0049] Obviously, under the premise of avoiding leakage of user privacy and ensuring the shooting effect, the camera device can also be set at other positions of the barrel door, or at any position in the area where the body and the barrel door overlap.

[0050] Refer to the following Figures 2 to 4 The control method of the drum washing machine of the present invention is described below. Figure 2 is a main flow chart of a control method for a drum washing machine according to an embodiment of the present invention. Figure 3 is a flow chart of a method for controlling a drum washing machine according to an embodiment of the present invention (I), Figure 4 Flowchart (II) of a method for controlling a drum washing machine according to an embodiment of the present invention.

[0051] like Figure 2 As shown, in a possible implementation manner, the control method of the laundry processing device of the present invention includes:

[0052] Step S100: when running the clothing recognition mode, obtaining the opening angle of the barrel door;

[0053] In the present invention, when washing clothes with a drum washing machine, it is first necessary to run a clothing recognition mode to obtain clothing information of the clothes to be washed, such as material, etc., through the clothing recognition mode, and then determine a suitable washing program based on the clothing information of the clothes to be washed. The drum washing machine washes the clothes according to the washing program, thereby achieving a better washing effect.

[0054] Of course, the clothing recognition mode can also be run at other times, such as during the spin-drying stage or the drying stage after washing the clothes.

[0055] In step S100, when the clothing recognition mode is running, the opening angle of the barrel door is first obtained.

[0056] In the present invention, the opening angle of the barrel door can be detected by a detection device such as a three-axis acceleration sensor, a six-axis acceleration sensor or a gyroscope, and the detection device for detecting the angle can be set on the barrel door.

[0057] Taking the detection device as a three-axis acceleration sensor as an example, the detection device partially performs continuous detection. During the process of the barrel door pivoting and opening relative to the body, the acceleration detected by the three-axis acceleration sensor starts to increase from zero. After increasing to a certain value, the acceleration gradually decreases to zero. At this time, the barrel door has completed the process from closing to opening, and the angle θ of the barrel door opening can be obtained.

[0058] Taking the detection device as a gyroscope as an example, the detection device continuously detects, and continuously detects the angular velocity of the barrel door switch through the gyroscope, and then determines the angle θ at which the barrel door is opened.

[0059] It should be noted that the detection principle and process of using the above-mentioned three-axis acceleration sensor, six-axis acceleration sensor or gyroscope and other detection equipment to detect the opening angle of the barrel door are conventional technical means in this field and will not be repeated here.

[0060] Step S200: determining the interval of the opening angle of the barrel door;

[0061] Step S300: Based on the judgment result, selectively start the camera device or adjust the opening angle of the barrel door.

[0062] In step S200, based on the opening angle of the barrel door obtained by the detection device in step S100, the interval in which the angle is located is determined. Then, based on the determination result, the camera device is selectively started or the opening angle of the barrel door is adjusted, that is, step S300 is executed.

[0063] Through such a control method, the camera device can be activated or the opening angle θ of the door can be adjusted according to the specific angle of the door, so that the camera device can be activated at a more appropriate time, and the image of the laundry obtained by the camera device will be clearer. Based on the image, the laundry can be better identified and a better laundry treatment effect can be obtained. At the same time, this also means that the camera device is not always working, so as to better avoid leaking the user's privacy.

[0064] like Figure 3As shown, in a possible implementation manner, the control method of the present invention includes:

[0065] Step S100: obtaining the opening angle of the barrel door;

[0066] Step S400: determining whether the opening angle of the barrel door is greater than or equal to a first preset angle and less than or equal to a second preset angle; if so, executing step S500; if not, executing step S600;

[0067] Step S500: starting the camera device;

[0068] Step S600: Control the operation of the power device;

[0069] In the present invention, the drum washing machine is equipped with a power device, such as a stepper motor, etc., through which the angle θ of the tub door opening can be adjusted. For example, the rotation angle of the stepper motor is controllable, and the purpose of adjusting the angle θ of the tub door opening is achieved by controlling the rotation angle of the stepper motor. Of course, without departing from the principle of the present invention, those skilled in the art can also adjust the angle θ of the tub door opening in other ways, such as manual adjustment.

[0070] In step S400, based on the opening angle of the barrel door obtained by the detection device in step S100, it is determined whether the current opening angle θ of the barrel door is greater than or equal to the first preset angle and less than or equal to the second preset angle, such as the first preset angle is 120° and the second preset angle is 140°. If yes, that is, the current opening angle θ of the barrel door is greater than or equal to the first preset angle and less than or equal to the second preset angle, such as θ is 130°, indicating that the current opening angle θ of the barrel door is relatively suitable, at which the camera device can obtain a relatively clear image of the laundry to be washed, at which time, the camera device is started, that is, step S500 is executed.

[0071] If not, that is, the current opening angle θ of the barrel door is less than the first preset angle or greater than the second preset angle, such as θ is 90°, or θ is 175°, it means that the current opening angle θ of the barrel door is too small or too large. At this time, the camera device is not started, but the power device is controlled to run, that is, step S600 is executed to adjust the opening angle θ of the barrel door.

[0072] By such a control method, the camera device will capture the image of the laundry only when the angle θ of the door opening is within the angle range between the first preset angle and the second preset angle, and a relatively clear image can be captured. When the angle θ of the door opening is outside the angle range, the camera device will not be activated, thereby better avoiding leakage of user privacy.

[0073] Step S700: obtaining the opening angle of the barrel door;

[0074] Step S800: determining whether the current opening angle of the barrel door is greater than or equal to the first preset angle and less than or equal to the second preset angle; if so, executing step S900; if not, returning to executing step S600;

[0075] Step S900: Control the power device to stop running.

[0076] After executing step S600, step S700 is executed, that is, in the process of adjusting the barrel door opening angle θ by the power device, the current barrel door opening angle θ is continuously detected. This is to obtain the current barrel door opening angle θ in real time during the adjustment process, so as to start the camera device or continue to adjust the barrel door opening angle θ according to the current barrel door opening angle θ in real time, so as to adjust the barrel door opening angle θ more accurately. Obviously, step S700 can also be executed at the same time as step S600.

[0077] In step S700, similar to the above step S100, the current opening angle θ of the barrel door can be obtained through detection devices such as a three-axis acceleration sensor, a six-axis acceleration sensor or a gyroscope. The specific acquisition process is similar and will not be repeated here.

[0078] In step S800, based on the barrel door opening angle θ obtained in step S700, the current barrel door opening angle θ is compared with the first preset angle and the second preset angle, such as the first preset angle is 120° and the second preset angle is 140°. If the current barrel door opening angle θ is greater than or equal to the first preset angle and less than or equal to the second preset angle, such as θ is 130°, it means that the current barrel door opening angle θ is exactly within the angle range of the first preset angle and the second preset angle, and the barrel door is already in a suitable position. In this case, the barrel door opening angle θ does not need to be increased or decreased, and the control power device is stopped, that is, step S900 is executed, and the camera device can be started.

[0079] If the current opening angle θ of the barrel door is still less than the first preset angle or greater than the second preset angle, such as θ is 90° or θ is 175°, it means that the barrel door is still not opened to the appropriate position. At this time, continue to control the operation of the power device, that is, return to execute step S600, and continue to adjust the opening angle θ of the barrel door through the power device until the opening angle θ of the barrel door is adjusted to the appropriate position.

[0080] Through the above-mentioned control method, when the opening angle θ of the barrel door is not within the angle range between the first preset angle and the second preset angle, the opening angle θ of the barrel door is adjusted by the power device, so that the barrel door is rotated until the opening angle θ of the barrel door is within the angle range, and the current opening angle θ of the barrel door is continuously obtained during the adjustment process, and the power device is controlled to operate or not operate in real time according to the current opening angle θ of the barrel door, so that the opening angle θ of the barrel door can be controlled more accurately.

[0081] like Figure 4 As shown, in a possible implementation manner, the control method of the present invention includes:

[0082] Step S100: obtaining the opening angle of the barrel door;

[0083] Step S400: determining whether the opening angle of the barrel door is greater than or equal to a first preset angle and less than or equal to a second preset angle; if so, executing step S500; if not, executing step S601;

[0084] Step S500: starting the camera device;

[0085] Step S601: further determining whether the opening angle of the barrel door is less than a first preset angle, if so, executing step S602; if not, executing step S603;

[0086] Step S602: Control the power device to operate to increase the opening angle of the barrel door;

[0087] Step S603: Control the power device to operate to reduce the opening angle of the barrel door.

[0088] In step S400, based on the angle θ of the tub door opening obtained in step S100, it is compared whether the angle θ of the tub door opening is greater than or equal to a first preset angle and less than or equal to a second preset angle, such as the first preset angle is 120° and the second preset angle is 140°. If so, such as θ is 130°, the camera device is started, that is, step S500 is executed to obtain an image of the laundry through the camera device.

[0089] If not, it is further determined whether the current opening angle θ of the barrel door is less than the first preset angle, such as 120°. If yes, that is, the current opening angle θ of the barrel door is less than the first preset angle, such as 90°, indicating that the current opening angle θ of the barrel door is too small. In this case, the shooting angle of the camera device is limited, and a clearer and more complete image of the laundry cannot be obtained. It is necessary to increase the opening angle θ of the barrel door through the power device, that is, execute step S602 to control the power device to increase the opening angle θ of the barrel door.

[0090] If not, it means that the current opening angle of the barrel door is an angle other than less than the first preset angle, greater than or equal to the first preset angle and less than or equal to the second preset angle, that is, the current opening angle of the barrel door is greater than the second preset angle. For example, the second preset angle is 140°, and θ is 175°, which means that the opening angle θ of the barrel door is too large. In this case, there is a risk of leaking user privacy. At this time, it is necessary to reduce the opening angle of the barrel door through a power device, that is, execute step S603 to control the operation of the power device to reduce the opening angle θ of the barrel door.

[0091] Through the above control method, by controlling the power device to increase or decrease the opening angle of the barrel door, the opening angle θ of the barrel door can be adjusted to within the angle range between the first preset angle and the second preset angle, so that the opening angle θ of the barrel door can be adjusted more accurately.

[0092] Combine the following Figure 5 , Figure 6 and Figure 8 The following is a detailed description of the possible implementation methods of adjusting the opening angle of the drum door of the drum washing machine of the present invention by the power device. Figure 5 1 is a flow chart of a control method for adjusting the opening angle of a drum door of a drum washing machine through a power device according to an embodiment of the present invention (I). Figure 6 Flow chart (II) of a control method for adjusting the opening angle of a drum door of a drum washing machine through a power device according to an embodiment of the present invention, Figure 8 It is a schematic structural diagram of the pivoting of the barrel door of a drum washing machine according to an embodiment of the present invention.

[0093] like Figure 5 and Figure 8 As shown, in a possible implementation manner, the control method of the present invention includes:

[0094] Step S6021: when the power device is controlled to operate, obtaining the rotation angle of the barrel door and the opening angle of the barrel door;

[0095] Step S6022: determine whether the rotation angle is within the first angle range, if so, execute step S6023; if not, execute step S6024;

[0096] Step S6023: Control the power device to stop running;

[0097] Step S6024: Control the power device to continue running.

[0098] The first angle range is determined based on the first preset angle, the second preset angle and the opening angle of the barrel door. For example, the first angle range is greater than or equal to the first difference and less than or equal to the second difference, and the first difference is the minimum rotation angle θ' of the barrel door. minThe second difference is the maximum rotation angle θ of the barrel door. max The difference between the angle θ of the barrel door opening. Here, the minimum rotation angle of the barrel door is θ' min The maximum rotation angle of the barrel door is approximately the same as the value of the first preset angle. max The value of the second preset angle is substantially the same as that of the second preset angle. Of course, they may also be different.

[0099] For example, the minimum rotation angle of the barrel door is 120°, the maximum rotation angle of the barrel door is 140°, and the opening angle of the barrel door is 90°, then the first difference is 30°, the second difference is 50°, and the first angle range is greater than or equal to 30° and less than or equal to 50°. Of course, the first angle range can also be determined in other ways, such as taking the average of the first preset angle and the angle θ of the barrel door opening as the first value, taking the average of the second preset angle and the angle θ of the barrel door opening as the second value, and the first angle range is greater than or equal to the first value and less than or equal to the second value.

[0100] If the opening angle of the tub door is too small, the camera device cannot obtain the image of the complete and clean laundry, so it is necessary to control the power device to increase the opening angle of the tub door. In the process of controlling the power device to increase the opening angle of the tub door, the rotation angle θ' of the tub door is obtained in real time, that is, step S6021 is executed, so that the rotation of the tub door can be adjusted more accurately.

[0101] In step S6021, similar to the above-mentioned steps S100 and S700, the rotation angle θ' of the barrel door can be obtained through detection devices such as a three-axis acceleration sensor, a six-axis acceleration sensor or a gyroscope. The specific acquisition process is similar and will not be repeated here.

[0102] In step S6022, based on the rotation angle θ' of the barrel door obtained in step S6021, it is determined whether the rotation angle θ' is within the first angle range, such as the first angle range being greater than or equal to 30° and less than or equal to 50°. If so, such as the rotation angle θ' is 40°, that is, the rotation angle θ' is within the first angle range, indicating that the barrel door has been rotated to a suitable position. When the barrel door is at this position, the camera device can already obtain a relatively complete and clear image of the laundry to be washed. At this time, there is no need to continue to increase the angle of the barrel door opening through the operation of the power device, then the power device is controlled to stop running, that is, step S6023 is executed.

[0103] If not, that is, the rotation angle θ' is outside the first angle range, it means that the barrel door has not been rotated to the appropriate position. In this case, if the rotation angle θ' is 20°, the rotation angle θ' is too small, the opening angle of the barrel door is still too small, and the camera device still cannot obtain a relatively complete and clear image of the laundry to be washed. Or, if the rotation angle θ' is 60°, the rotation angle θ' is too large, the opening angle of the barrel door is too large, the shooting angle of the camera device is biased, and a relatively complete and clean image of the laundry to be washed cannot be obtained. At this time, it is necessary to control the power device to continue to run to continue to adjust the opening angle of the barrel door, and continue to increase or decrease the opening angle of the barrel door. Then, the power device is controlled to continue to run, that is, execute step S6024.

[0104] Through the above control method, the operation of the power device is controlled according to the rotation angle of the barrel door, so that the opening angle of the barrel door can be controlled more accurately and the opening angle of the barrel door can be better adjusted to between the first preset angle and the second preset angle.

[0105] like Figure 6 and Figure 8 As shown, in a possible implementation manner, the control method of the present invention includes:

[0106] Step S6031: when the power device is controlled to operate, obtaining the rotation angle of the barrel door and the opening angle of the barrel door;

[0107] Step S6032: determine whether the rotation angle is within the second angle range, if so, execute step S6033; if not, execute step S6034;

[0108] Step S6033: Control the power device to stop running;

[0109] Step S6034: Control the power device to continue running.

[0110] The second angle range is determined based on the first preset angle, the second preset angle and the angle of the barrel door opening. For example, the second angle range is greater than or equal to the third difference and less than or equal to the fourth difference, and the third difference is the angle θ of the barrel door opening and the minimum rotation angle θ' min The fourth difference is the difference between the opening angle θ of the barrel door and the maximum rotation angle θ' max Here, the minimum rotation angle of the barrel door is θ' min The maximum rotation angle of the barrel door is approximately the same as the value of the first preset angle. max The value of the second preset angle is substantially the same as that of the second preset angle. Of course, they may also be different.

[0111] For example, the minimum rotation angle of the barrel door is 120°, the maximum rotation angle of the barrel door is 140°, and the opening angle of the barrel door is 175°. Then, the first difference is 35°, the second difference is 55°, and the second angle range is greater than or equal to 35° and less than or equal to 55°.

[0112] Of course, the second angle range can also be determined in other ways, such as taking the average of the first preset angle and the angle θ of the barrel door opening as the first value, taking the average of the second preset angle and the angle θ of the barrel door opening as the second value, and the first angle range is greater than or equal to the first value and less than or equal to the second value.

[0113] When the barrel door is opened at an angle that is too large, there is a problem of leaking user privacy, so it is necessary to control the power device to reduce the barrel door opening angle. In the process of controlling the power device to reduce the barrel door opening angle, the barrel door rotation angle θ' is obtained in real time, that is, step S6031 is executed, so that the barrel door rotation can be adjusted more accurately.

[0114] In step S6031, similar to the above-mentioned steps S100, S700, and S6021, the rotation angle θ' of the barrel door can be obtained through detection devices such as a three-axis acceleration sensor, a six-axis acceleration sensor, or a gyroscope. The specific acquisition process is similar and will not be repeated here.

[0115] In step S6032, based on the rotation angle θ' of the barrel door obtained in step S6031, it is determined whether the rotation angle θ' is within the second angle range, such as the second angle range is greater than or equal to 35° and less than or equal to 55°. If so, such as the rotation angle θ' is 45°, that is, the rotation angle θ' is within the second angle range, indicating that the barrel door has been rotated to a suitable position. When the barrel door is at this position, the camera device can already obtain a relatively complete and clear image of the laundry to be washed, and there is no risk of leaking user privacy. At this time, there is no need to continue to reduce the angle of the barrel door opening through the operation of the power device, then the power device is controlled to stop running, that is, step S6033 is executed.

[0116] If not, that is, the rotation angle θ' is outside the second angle range, it means that the barrel door has not been rotated to the appropriate position. In this case, if the rotation angle θ' is 20°, the rotation angle θ' is too small, the opening angle of the barrel door is still too large, and the shooting angle of the camera device is biased, and a relatively complete and clean image of the laundry to be washed cannot be obtained. Or, if the rotation angle θ' is 60°, the rotation angle θ' is too large, the opening angle of the barrel door is too small, and the camera device cannot obtain a relatively complete and clear image of the laundry to be washed. At this time, it is necessary to control the power device to continue to run to continue to adjust the opening angle of the barrel door, and continue to reduce or increase the opening angle of the barrel door. Then, the power device is controlled to continue to run, that is, execute step S6034.

[0117] Through the above control method, the operation of the power device is controlled according to the rotation angle of the barrel door, so that the opening angle of the barrel door can be controlled more accurately and the opening angle of the barrel door can be better adjusted to between the first preset angle and the second preset angle.

[0118] Refer to the following Figure 7 To illustrate the possible specific implementation of the control method of the present invention. Figure 7 Flowchart (III) of a method for controlling a drum washing machine according to an embodiment of the present invention.

[0119] like Figure 7 As shown, in a possible implementation manner, the control method of the present invention includes:

[0120] Step S100: obtaining the opening angle of the barrel door;

[0121] Step S110: Determine whether the opening angle of the barrel door is zero, if yes, execute step S120; if no, execute step S130;

[0122] Step S120: issuing a prompt message of "open the barrel door";

[0123] Step S130: further determining whether the opening angle of the barrel door is greater than or equal to the first preset angle and less than or equal to the second preset angle, if so, executing step S150; if not, executing step S140;

[0124] Step S140: Control the operation of the power device;

[0125] Step S150: starting the camera device and sending a prompt message of "putting in clothes";

[0126] Step S160: Acquire the image of the laundry;

[0127] Step S170: determining the laundry information of the laundry based on the image;

[0128] Step S180: determining a laundry washing program based on the laundry information;

[0129] Step S190: Control the drum washing machine to run the laundry washing program.

[0130] In step S110, based on the opening angle θ of the tub door obtained in step S100, it is determined whether the opening angle θ of the tub door is zero. If so, it means that the tub door is closed and not opened at all, and the user needs to wash the laundry. At this time, it is necessary to remind the user to open the tub door, that is, execute step S120 and send a prompt message of "open the tub door".

[0131] Here, after the prompt message is issued, the way to open the barrel door may be that the user opens the barrel door manually, such as pulling it outward with force, or pressing a door opening button on the control panel of the drum washing machine, etc. The way to open the barrel door may also be to control the power device to open the barrel door outward. Without departing from the principles of the present invention, those skilled in the art may flexibly select a specific implementation method for opening the barrel door according to a specific application scenario, and the present invention does not limit it.

[0132] It should be noted that the prompt information in step S120 may also be of other types, such as the barrel door is not open, etc. Those skilled in the art can flexibly select the type of prompt information according to the specific application scenario, as long as it can serve as a prompt.

[0133] In this embodiment, the prompt message of "open the barrel door" can be issued by the air conditioner or APP client in the form of voice, text, alarm, etc. The present invention does not impose any limitation on the specific prompt method as long as the purpose of the prompt can be achieved.

[0134] In step S130, based on the barrel door opening angle θ obtained in step S100, it is further determined whether the barrel door opening angle θ is greater than or equal to a first preset angle and less than or equal to a second preset angle, such as the first preset angle is 120° and the second preset angle is 140°. If not, such as θ is 90° or θ is 175°, indicating that the current position of the barrel door is not suitable, the power device is controlled to adjust the barrel door opening angle, that is, execute step S140, so that the barrel door can be rotated to the barrel door opening angle between the first preset angle and the second preset angle.

[0135] If θ is 130°, it means that the angle θ of the door opening is between the first preset angle and the second preset angle. At this time, the camera device is started and a prompt message of "putting in clothes" is sent, that is, step S150 is executed. In this case, the camera device is ready to capture images of the laundry, and sends a prompt message of "putting in clothes" to remind the user that the laundry can be put in. When the user takes the laundry to the drum washing machine and prepares to put it in, the laundry enters the field of view of the camera device, so that the image of the complete and clean laundry can be captured.

[0136] It should be noted that, although in step S150, starting the camera device and sending the prompt message of "putting in clothes" are performed simultaneously, it is obvious that the prompt message of "putting in clothes" can also be sent after starting the camera device. Those skilled in the art can flexibly select the execution order of starting the camera device and sending the prompt message of "putting in clothes" according to specific application scenarios, as long as the camera device can obtain the image of the clothes to be washed and remind the user to put in clothes.

[0137] It should be noted that the prompt information in step S150 may also be of other types, such as putting away clothes, washing clothes, etc. Those skilled in the art may flexibly select the type of prompt information according to the specific application scenario, as long as it can serve as a prompt.

[0138] In this embodiment, the "put in clothes" prompt information can be issued by the air conditioner or APP client in the form of voice, text, alarm, etc. The present invention does not impose any limitation on the specific prompt method as long as the purpose of the prompt can be achieved.

[0139] In step S160, an image of the laundry is acquired based on the camera device activated in step S150.

[0140] In step S170, based on the image of the laundry obtained in step S160, the laundry information of the laundry is determined. The laundry information may be information such as the material and category of the laundry. The laundry information of the laundry may be determined based on the image by building a neural network, deep learning, and other methods. This determination method belongs to the conventional technical means in the art and will not be described in detail here.

[0141] In step S180, based on the laundry information of the laundry determined in step S170, a suitable laundry washing program is determined. Taking the laundry information of the laundry as the material of the laundry as an example, the drum washing machine includes a control module, the database of which has a plurality of reference laundry washing programs corresponding to the material of each piece of laundry, the material of the laundry determined in step S170 is matched with a plurality of laundry materials in the database, the reference laundry washing program corresponding to the material of the laundry with the highest matching degree with the material of the laundry is determined as the target laundry washing program, and then the target laundry washing program is determined as the laundry washing program.

[0142] In step S190, based on the laundry washing program determined in step S180, the drum washing machine is controlled to run the laundry washing program, so as to obtain a better washing effect.

[0143] Through the above control method, a suitable laundry processing program can be determined specifically according to the laundry information of the laundry, so that the laundry can be washed better.

[0144] In a possible implementation, the camera device is configured to capture an image of the washing drum during the operation of the drum washing machine. The control method of the present invention further includes: capturing an image of the washing drum during the operation of the drum washing machine, and determining washing process information based on the image. The washing process information may be information such as washing water and lint. Based on the washing process information, the user can understand the specific situation in the washing drum during the washing process in detail, which is more intuitive.

[0145] Although the various steps in the above embodiment are described in the above-mentioned order, those skilled in the art can understand that in order to achieve the effect of this embodiment, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in a reverse order. These simple changes are within the scope of protection of the present invention.

[0146] In summary, in the preferred technical solution of the present invention, when the clothing recognition mode is running, the camera device is selectively started or the angle of the barrel door opening is adjusted based on the interval where the barrel door opening angle is located, so that the camera device can be started at a more appropriate time, and the image of the laundry obtained by the camera device will be clearer. Based on the image, the laundry can be better identified and a better laundry treatment effect can be obtained. At the same time, it can also avoid leaking the user's privacy. When the barrel door opening angle is greater than or equal to the first preset angle and less than or equal to the second preset angle, the camera device is started, and a complete and cleaned image is obtained through the camera device. When the barrel door opening angle is less than the first preset angle, or greater than the second preset angle, the power device is controlled to operate to adjust the barrel door opening angle, so that the barrel door rotates to the barrel door opening angle between the first preset angle and the second preset angle, so that the image of the laundry can be better obtained.

[0147] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0148] In addition, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims of the present invention, any one of the claimed embodiments may be used in any combination.

[0149] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
