[0037] The beneficial effects of the technical solution provided by the embodiments of the present application are:

[0038] In the first aspect, the present application provides a method for controlling light tracking during drying. The implementation of this method can achieve the following effects:

[0039] (1) When the light chasing function is turned on, the light intensity of the clothes drying rod is first obtained, and the light chasing operation is started when the light intensity of the clothes drying rod meets the light chasing condition. Specifically, the clothes drying rod is controlled to move up and down in a predetermined direction according to the current position of the clothes drying rod, and the light intensity of the clothes drying rod during the lifting process in the predetermined direction is collected to determine the position of the clothes drying rod when the light intensity meets the condition, and finally the clothes drying rod is controlled to be in the above-mentioned determined position. It can be seen that in the method of the present application, each time the light chasing function is turned on, it is determined whether to start the light chasing operation based on the current light intensity of the clothes drying rod. After the light chasing operation is started, the lifting control can be performed according to the current state (position) of the clothes drying rod, and the best drying position can be found for the clothes drying rod based on the light intensity information during the lifting process of the clothes drying rod. It can be seen that the method of the present application can realize the first light chasing adaptively each time the light chasing function is turned on, so that the clothes drying rod can find the best drying position when the light chasing is turned on, effectively improving the drying efficiency of the clothes drying machine.

[0040] (2) In the present invention's method for controlling the light-following of clothes, when the light-following function is turned on and the clothes-drying rod is at the top position, the clothes-drying rod is controlled to move downward and descend to the bottom position, and then the position where the light intensity is the largest and greater than the preset value is found, and this position is used as the drying position that meets the conditions, i.e., the optimal drying position, and the clothes-drying rod is controlled to be at this position; as can be seen from the above, when the present invention is chasing the light for the first time, the optimal drying position is selected after the clothes-drying rod is completely lowered, which can effectively avoid the defect that the clothes-drying rod may stay at a position after the optimal drying position due to the information lag in the real-time control of the clothes-drying rod, and the clothes on the clothes-drying rod miss the position with the maximum light intensity. In addition, when the light-following function is turned on and the clothes-drying rod is at the top position, the present invention's method can also make a real-time judgment on the light intensity during the process of the clothes-drying rod descending. When it is detected that the light intensity is greater than the preset value, the clothes-drying rod is controlled to stop moving, so that the clothes-drying rod stays at a position with relatively large light intensity. Based on this, it is possible to find the drying position that meets the conditions in real time during the process of the clothes-drying rod descending, and ensure that the clothes-drying rod finds the best drying position with the shortest movement distance.

[0041] (3) In the present application's method for controlling the light chasing of clothes drying, when the light chasing function is turned on and the clothes drying rod is at the bottom position, the clothes drying rod is controlled to move upward and find a position where the current light intensity is less than the last saved data value (the last data value is the currently saved maximum data value and is greater than the preset value) during the rising process, and the position is used as a drying position that meets the conditions. The above method utilizes the hysteresis of receiving light sensor information so that the clothes on the clothes drying rod are just at the drying position with the maximum light intensity, which effectively improves the drying efficiency. In addition, the present application searches for the current light intensity during the rising process of the clothes drying rod to meet the requirement of being less than the last saved data value and the last data value being the maximum data value. Compared with directly finding the maximum data value, when the clothes drying rod has a section of running positions where all the positions are the maximum data value and are greater than the second preset value, the above operation can make the clothes drying rod stay at the highest position that meets the light intensity requirement, further improving the effect of clothes drying.

[0042] (4) In the present application's method for controlling the light tracking of the drying rod, when the light tracking function is turned on and the drying rod is in the middle position (i.e., between the top and bottom positions), the drying rod is first controlled to descend and the light intensity is determined during the descent process, and the drying rod is controlled to stay at a position where the light intensity is relatively large and greater than a preset value. If a position that meets the above conditions is not found during the descent process, the drying rod can be controlled to rise after the drying rod reaches the bottom position, and during the rise process, a position where the current light intensity is less than the last saved data value (the last data value is the current maximum saved data value and greater than the preset value) is found, and this position is used as the optimal position for the drying rod to stay. Based on this, the present application method can ensure that a drying position that meets the light requirements is found when the travel distance is small, thereby improving the efficiency of the first light tracking. In addition, when the light tracking function is turned on and the drying rod is relatively close to the top position, the drying rod can also be controlled to move upward first. If a position that meets the conditions is not found during the rise process, the drying rod can be controlled to descend and a drying position that meets the conditions is found during the descent process, thereby further improving the efficiency of the first light tracking.

[0043] (5) In the drying and chasing light control method of the present application, the light intensity of the clothes drying rod during the rising or falling process is collected in a preset sampling period, and each N data collected is listed as a group. The data value calculated by averaging the data in the same group is saved as the final light intensity value; it can be seen that the method of the present application determines the light intensity value of the clothes drying rod at each position based on multiple light intensity data values, can more accurately reflect the actual light intensity at each position, can effectively avoid the detection error caused by a single light intensity value, and ensure the effectiveness of the chasing light control.

[0044] (6) In the drying light tracking control method of the present application, after the first light tracking, the light offset direction (including light moving up or down) is further detected based on the collected light intensity changes. When the light moves up or down, the clothes drying on the clothes drying rod can be controlled to move up or down so that the clothes drying on the clothes drying rod follow the direction of light movement, so that they are always in the relatively strongest light position, so as to achieve continuous light tracking operation.

[0045] (7) In the method for controlling the light chasing of clothes drying in the present application, after the light chasing operation is started, the light intensity of the clothes drying rod is monitored in real time to determine whether to turn off the light chasing function. When it is detected that the light intensity of the clothes drying rod is less than a certain preset value and the duration exceeds the preset time, the light chasing function of the clothes drying rod can be controlled to turn off. After the light chasing function is turned off, if the light intensity returns to above the preset value and the duration exceeds the preset time, the light chasing function can be controlled to turn on. Therefore, the method of the present application can realize automatic control of turning on and off the light chasing function. When the light intensity is weak and light chasing is not needed, turning off the light chasing function can save power consumption.

[0046] (8) In the light-chasing control method for clothes drying of the present application, before starting the light-chasing operation, the daytime start and end time of the installation location can be determined based on the latitude and longitude information of the clothes drying machine installation location. Therefore, when the current time reaches the daytime start time, the light-chasing function can be controlled to be turned on, and when the current time reaches the end time, the light-chasing function can be controlled to be turned off. This can realize automatic control of the light-chasing function on and off based on time information, which brings great convenience to the light-chasing control of the clothes drying machine. In addition, when the clothes drying machine host is connected to the Internet, the present application can also control the light-chasing function on and off based on weather change information. For example, after the light-chasing function is turned on, when the weather changes from sunny to cloudy, the light-chasing function can be controlled to be turned off to stop the light-chasing and control the clothes drying rod to be at the top position. After that, when the weather turns sunny, the light-chasing function can be turned on again. It can be seen that the method of the present application can adapt to weather changes and realize automatic light-chasing control according to weather conditions.

[0047] In a second aspect, the present application provides a method for controlling continuous light tracking during drying. The implementation of this method can achieve the following effects:

[0048] (1) The continuous light tracking control method for drying clothes in the present application first determines the light intensity change of the clothes drying rod based on the light intensity information of the clothes drying rod, and then determines the light offset direction according to the light intensity change of the clothes drying rod; finally, according to the light offset direction, the clothes drying rod is controlled to move up and down, and the light intensity during the lifting and lowering process of the clothes drying rod is collected to determine the position of the clothes drying rod when the light intensity meets the conditions, and the clothes drying rod is controlled to be in the above-determined position. As can be seen from the above, the method of the present application can continuously track the changing light in the drying area based on the real-time offset light, so that the clothes drying on the clothes drying rod can always be in the best drying position, effectively improving the efficiency of the clothes drying machine.

[0049] (2) In the method for controlling continuous light tracking during drying of the present application, the direction of light offset can be determined based on the difference in the total light intensity at various positions on the drying rod along the direction of movement of the drying rod within a specified time, wherein the specified time refers to the time from the last time the drying rod stopped to the current moment to be determined. Therefore, the method of the present application determines the direction of light offset based on the light intensity information at each moment in the specified time at the upper and lower positions of the drying rod, and takes into account the changes in light intensity at each moment, and can more accurately and quickly determine the direction of light offset. In addition, the method of the present application can determine the direction of light offset based on multiple groups of positions on the drying rod along the direction of movement of the drying rod, and can combine the changes in light intensity at multiple different positions in the horizontal direction of the drying rod, so the accuracy of determining the direction of light offset is higher. Furthermore, if the upper and lower widths of the clothes-drying pole allow, more than three positions can be selected in the same group of positions to collect light intensity. Specifically, the sum of the light intensity differences at the positions of each two adjacent light sensors can be calculated first. The sum of the light intensity differences calculated above can be averaged as the sum of the light intensity differences for the group of positions. Finally, the total light intensity difference is calculated based on the sum of the light intensity differences for each group of positions to determine the direction of light offset. The above method of the present application takes into account the changes in light intensity at multiple positions in the direction of movement of the clothes-drying pole, i.e., the longitudinal direction, and can also more accurately determine the direction of light offset on the clothes-drying pole.

[0050] (3) In the continuous light-chasing control method for drying clothes in the present application, during the continuous light-chasing process, when it is detected that the light is moving upward, the clothes-drying rod is controlled to move upward and find a position where the current light intensity is less than the last saved data value (the last data value is the current maximum data value saved and greater than the preset value) during the rising process, and the position is used as a drying position that meets the conditions. The above method uses the hysteresis of receiving light sensor information so that the clothes on the clothes-drying rod are just at the drying position with the maximum light intensity, which effectively improves the drying efficiency. In addition, the current light intensity found by the present application during the rising process of the clothes-drying rod satisfies the requirement of being less than the last saved data value and the last data value being the maximum data value. Compared with directly finding the maximum data value, when the clothes-drying rod has a section of running positions where all the positions are the maximum data value and greater than the preset value, the above operation can make the clothes-drying rod stay at the highest position that meets the light intensity, further improving the effect of drying clothes.

[0051] (4) In the method for controlling continuous light tracking during drying of clothes in the present application, during the continuous light tracking process, when it is detected that the light is moving downward, the drying rod is first controlled to descend and the best drying position is found during the descent process. If the best drying position cannot be found during the descent process, after the drying rod descends to the bottom, the drying rod is controlled to move upward from the bottom and the best drying position is found during the upward movement. Based on this, the method of the present application can find a better drying position even when the light is moving downward, which is generally when the light is weakened.

[0052] (5) In the continuous light-chasing control method for drying clothes in the present application, the light intensity of the clothes-drying rod during the rising or falling process is collected in a preset sampling period, and each N data collected is listed as a group. The data value calculated by averaging the data in the same group is saved as the final light intensity value; it can be seen that the method of the present application determines the light intensity value of the clothes-drying rod at each position based on multiple light intensity data values, can more accurately reflect the actual light intensity at each position, can effectively avoid the detection error caused by a single light intensity value, and ensure the effectiveness of the light-chasing control.

[0053] (6) In the method for controlling continuous light chasing during drying of clothes in the present application, whether to turn off the light chasing function is also determined by real-time monitoring of the light intensity of the clothes drying rod. When it is detected that the light intensity of the clothes drying rod is less than a certain preset value and the duration exceeds the preset time, the light chasing function of the clothes drying rod can be controlled to turn off. After the light chasing function is turned off, if the light intensity returns to above the preset value and the duration exceeds the preset time, the light chasing function can be controlled to turn on. Therefore, the method of the present application can realize automatic control of turning on and off the light chasing function. When the light intensity is weak and light chasing is not needed, turning off the light chasing function can save power consumption.

[0054] (7) In the method for controlling continuous light tracking during drying of clothes in the present application, the starting time and ending time of the daytime at the installation location can also be determined based on the latitude and longitude information of the installation location of the clothes drying machine. Therefore, when the current time reaches the starting time of the daytime, the light tracking function can be controlled to be turned on, and when the current time reaches the ending time, the light tracking function can be controlled to be turned off. This method can realize automatic control of the turning on and off of the light tracking function based on time information, which brings great convenience to the light tracking control of the clothes drying machine.

[0055] (8) In the method for controlling continuous light tracking during drying of clothes in the present application, when the main unit of the clothes drying machine is connected to the Internet, the present application can also control the turning on and off of the light tracking function based on weather change information. For example, during the light tracking process, when the weather changes from sunny to cloudy, the light tracking function can be controlled to be turned off to stop the light tracking and control the clothes drying rod to be at the top position. After that, when the weather turns sunny, the light tracking function can be continued again. It can be seen that the method of the present application can adapt to the changes in the weather and realize automatic light tracking control according to weather conditions.

[0056] On the third aspect, the present application provides a method for controlling light-chasing drying. By starting the light-chasing operation only when the current drying condition information of the clothes drying machine meets the light-chasing conditions, it can avoid power consumption waste caused by ineffective light-chasing. The designated drying position of the clothes drying machine controlled during the light-chasing operation is obtained by matching historical data. After determining the designated drying position, the drying position of the clothes can be automatically adjusted so that the clothes are always in a drying position with appropriate light intensity. There is no need to collect time-consuming and energy-consuming light intensity and calculate it before determining the designated drying position before each light-chasing drying. It can significantly improve the efficiency and intelligence of light-chasing drying.

[0057] Fourthly, the present application provides a clothes drying control system, in which the controller controls the light intensity detector to move along the clothes drying rod through the first power device and collects light intensity information during the movement, and the light intensity detector can also move up and down with the clothes drying rod and collect light intensity information during the lifting process. The controller can determine the degree of drying of clothes at different positions based on the light intensity information collected at different positions in the horizontal and vertical directions, so as to effectively help to intelligently and accurately identify sunlight for clothes drying.

[0058] In a fifth aspect, the present application provides a sun-drying and tracking light control system, which can achieve the following effects:

[0059] (1) The light-chasing control system for clothes drying in the present application includes a controller and a light-chasing device. The light-chasing device includes a plurality of light sensors connected to the controller, wherein at least two light sensors are arranged along the direction of movement of the clothes drying rod; each light sensor is arranged on the clothes drying rod of the clothes drying machine, and is used to monitor the light intensity information on the clothes drying rod in real time and send it to the controller; the controller is directly or indirectly connected to the motion drive mechanism of the clothes drying rod, and determines the light offset direction according to the change of light intensity to control the movement of the clothes drying rod, and determines the drying position of the clothes drying rod based on the light intensity information during the movement of the clothes drying rod. The system of the present application can determine the light offset direction by at least two light sensors arranged along the direction of movement of the clothes drying rod, and then control the clothes drying rod to move to a drying position that meets the drying conditions based on the light offset direction, thereby realizing continuous light-chasing, so that the clothes drying on the clothes drying rod can always be in the best drying position, and effectively improving the drying efficiency of the clothes drying machine.

[0060] (2) The present application's light-chasing control system may include multiple groups of light sensors, each of which may be arranged at a different position in the horizontal direction of the drying rod. Based on this, the present application can determine the direction of light offset by combining the light changes of multiple groups of light sensors, making the determination of the light offset direction more accurate. In addition, in the same group of light sensors, more than three light sensors may be arranged along the direction of movement of the drying rod. Based on this, multiple light sensors can be combined to determine the light changes, thereby further determining the light offset direction, and also improving the accuracy of determining the light offset direction on the drying rod.

[0061] (3) In the clothes drying light tracking control system of the present application, the light tracking device includes a mounting body, and the light sensor can be set on the mounting body, and then set on the clothes drying rod through the mounting body. Based on this, the present application can flexibly adjust the position of the light sensor on the clothes drying rod, which is suitable for use in clothes drying machines under various installation conditions, such as different orientations, different areas, and other installation conditions. In addition, one or more outwardly protruding Fresnel hemispherical lenses can be embedded on the surface of the mounting body, and the light sensor can be set within the lens to improve the sensitivity of light intensity acquisition.

[0062] (4) In the present application, the controller of the light-chasing control system for drying clothes can be a controller of a light-chasing device independently set on the clothes-drying rod, or the main controller of the clothes-drying machine can be directly used; in the former case, the controller can communicate with the main controller of the clothes-drying machine through a wireless communication module, thereby realizing the lifting and lowering movement of the clothes-drying rod through the main controller of the clothes-drying machine, so as to achieve continuous light-chasing, which has the advantages of simple structure and convenient control. In addition, when the controller is independently set on the clothes-drying rod, it can be connected to a solar panel to power the controller and light sensor on the clothes-drying rod, without the need to input power from the main machine of the clothes-drying machine for wired power supply, making the structure simpler and directly applicable to the current clothes-drying machine without the need to significantly improve the structure of the current clothes-drying machine.

[0063] In a sixth aspect, the embodiments of the present application provide a light-tracking clothes drying machine, which can achieve the following effects:

[0064] (1) The light-chasing clothes drying machine described in the present application can sense light and feed back light information to the host by setting a photosensitive module on the lifting device and / or the drying rack. The host controls the drying rack or the hook of the drying rack to reach the designated drying position according to the light information, thereby allowing most of the surface of the clothes to be exposed to sunlight as much as possible or extending the exposure time to sunlight as much as possible.

[0065] (2) The light-chasing clothes drying machine described in the present application has multiple photosensitive modules arranged at intervals, which is conducive to simultaneously sensing the light at multiple positions horizontally and / or vertically to obtain the position with the strongest light.

[0066] (3) The light-chasing clothes drying machine described in this application movably connects the photosensitive module to the drying rack. Compared with a fixed setting method, the photosensitive module can be sensed in more and more flexible positions.

[0067] Additional aspects and advantages of the present application will be given in part in the following description, which will become apparent from the following description, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0091] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems of the prior art. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0092] The following is a detailed description of the drying and chasing light control method provided in the embodiment of the present application.

[0093] At present, some of the light-tracking technologies for clothes drying machines are completely dependent on the light-tracking model set in the background. Specifically, the background light-tracking model analyzes and calculates the parameters input in advance by the user and some parameters obtained through the network to obtain the lighting conditions, and then controls the lifting and lowering of the clothes drying machine; some use light sensors set at fixed positions such as wall-mounted remote controls to detect the lighting conditions to control the lifting and lowering of the clothes drying machine; the above-mentioned light-tracking technologies have poor effects, and there is no first-time adaptive light-tracking operation process. It is impossible to control the clothes drying machine to be in the best drying state when starting light-tracking, and the light-tracking efficiency needs to be improved.

[0094] Based on the problems existing in the prior art, this embodiment provides a method for controlling light chasing during drying. The method is applied to a clothes drying machine. The clothes drying machine includes a main unit and a clothes drying rod. The clothes drying rod is arranged below the main unit through a steel wire rope. The main unit is provided with a main controller, a motor, a drying module, a lighting module, etc. The main controller is connected to the motor through a motor driver, and the steel wire rope is controlled by the motor to realize the automatic lifting of the clothes drying rod. In addition, the main controller can be connected to functional modules such as the drying module and the lighting module to control the working status of the drying module and the lighting module. The light chasing control method of this embodiment can be implemented by a control system provided on the clothes drying machine. The control system is connected to a light sensor provided on the clothes drying rod. The control system can be directly the main controller in the clothes drying machine main unit, or it can be a separate controller. As shown in Figure 1, the light chasing control method for drying includes:

[0095] SA. Obtain the light intensity of the clothes drying rod when the light chasing function is turned on, and determine whether the light chasing condition is met based on the light intensity of the clothes drying rod. In this embodiment, when the light chasing function is turned on, if the light intensity of the clothes drying rod is greater than the preset value A, it is determined that the light chasing condition is met.

[0096] In this embodiment, a light sensor is installed on the clothes drying rod of the clothes drying machine to detect the light intensity on the rod. To meet the first light tracking requirement, this embodiment can be equipped with one or more light sensors. If multiple light sensors are used, multiple sensors can be arranged in the horizontal direction (left-right direction) of the clothes drying rod and / or in the direction of movement (up-down direction) of the clothes drying rod.

[0097] In this embodiment, the light sensor may be an ambient light sensor of model BH1750FVI, which can measure the intensity of ambient light (lumen value lux) and can clearly distinguish between sunlight and indoor light.

[0098] SB. When the light chasing condition is met, that is, when the light chasing function is turned on and the light intensity on the clothes drying rod is greater than the preset value A, the following first light chasing operation is initiated:

[0099] Based on the current position of the clothes drying rod, the clothes drying rod is controlled to move up and down in a predetermined direction. The light intensity during the process of the clothes drying rod being raised and lowered in the predetermined direction is collected to determine the position of the clothes drying rod when the light intensity meets the conditions, i.e., the optimal drying position. In this embodiment, by controlling the clothes drying rod to move up and down in the predetermined direction, the point where the light intensity is relatively high or maximum in the vertical space where the clothes drying rod is operating is found and used as the optimal drying position for the clothes drying machine.

[0100] In this embodiment, the preset value A can be set to 1000 lux. That is, when the light intensity on the clothes drying machine is greater than 1000 lux after the light tracking function is turned on, the first light tracking operation is started to determine the position of the clothes drying rod when the light intensity meets the conditions; otherwise, the light tracking function is turned off and waits until the next time the light tracking function is turned on.

[0101] SC, control the drying rod to be at a position where the light intensity of the drying rod meets the conditions determined above, thereby realizing the first light chasing operation.

[0102] In this embodiment, as shown in FIG2 , the clothes-drying rod is controlled to move up and down in a predetermined direction according to its current position, and the position of the clothes-drying rod when the light intensity meets the conditions is determined. The specific process of controlling the clothes-drying rod to be in the above-determined position is as follows:

[0103] (1) When the current position of the drying rod is at the top position, for example, when the drying rod is at the upper limit position, perform the following operations to achieve the first light tracking:

[0104] Step S1-1, controlling the drying rod to perform a downward movement.

[0105] Step S1-2: collecting the light intensity of the clothes-drying pole at a preset sampling period during the process of the clothes-drying pole descending; collecting N data as a group, averaging the data in the same group and saving the calculated data value;

[0106] In this embodiment, during the descent of the clothes-drying rod, the light intensity of the clothes-drying rod is collected with a sampling period of 100ms; every 10 data collected can be grouped as a group, that is, N is set to 10, that is, the 10 data collected every 1s are grouped as a group. For example, the light intensity data N1 to N10 are collected in the 1st second, and the light intensity data N11 to N20 are collected in the 2nd second. Then the light intensity data N1 to N10 are classified into the first group, and the data value M1 is obtained by averaging the data N1 to N10. N11 to N20 are classified into the second group, and the data value M2 is obtained by averaging the data N11 to N20. And so on, the data values ​​corresponding to each group of light intensity data are obtained and saved in the buffer.

[0107] Step S1-3: After the clothes-drying rod descends to the bottom position, compare the stored data values; obtain a data value that is greater than the first preset value and is the largest, determine the corresponding set of data for calculating the data value, and determine the position of the clothes-drying rod at the time the set of data is collected as the position when the light intensity on the clothes-drying rod meets the condition. That is, obtain a data value that is greater than the first preset value and is the largest from the stored data values, determine the corresponding set of data for calculating the data value, and determine the position of the clothes-drying rod at the time the set of data is collected as the position when the light intensity on the clothes-drying rod meets the condition; if no data value greater than the first preset value exists in the stored data values, control the clothes-drying rod to ascend to the top, and disable the light-chasing function.

[0108] It usually takes about 15 seconds for the clothes-drying pole to be lowered from the top to the bottom. Assuming it is 15 seconds, 15 groups of data will be collected after the clothes-drying pole is lowered to the bottom, corresponding to 15 data values, namely M1, M2, ..., M15. Compare the 15 data values ​​and select the largest data value, such as M8. Compare M8 with the first preset value. If it is greater than the first preset value, determine and calculate a group of data for M8, namely N81, N82, N83, ...N90. The position of the clothes-drying pole when this group of data is collected is used as the position when the light intensity of the clothes-drying pole meets the conditions. Specifically, it can be the position of the clothes-drying pole when any data from N81 to N90 is collected, and preferably it can be the position of the clothes-drying pole when N85 is collected.

[0109] In this embodiment, the first preset value can be set to 10000 lux, and can be specifically set according to the actual local lighting conditions.

[0110] In this embodiment, if the maximum data value in the buffer is not greater than the first preset value, the drying rod is controlled to rise to the top position and the light tracking function is disabled. This indicates that there is no position that meets the light intensity requirements under the current lighting environment. Therefore, the drying rod is controlled to rise to the top position for drying, and the light tracking function is disabled to save energy.

[0111] The above steps enable this embodiment to determine the optimal drying position after the rod has completed its entire travel. This effectively avoids the problem of information lag in real-time rod control, which can cause the rod to remain at a position beyond the optimal drying position, causing the clothes on the rod to miss the point of maximum light intensity. For example, if the rod determines the drying position by calculating data values ​​in real time, that is, not after the entire travel, the lag caused by information transmission, processing, and calculation can mean that by the time the position that meets the drying conditions is calculated, the rod has actually already descended to the next position. Therefore, the clothes under the rod are likely to have missed the original optimal drying position. The above execution process of this embodiment avoids this problem.

[0112] Alternatively, when the current position of the drying rod is at the top, such as when the drying rod is at the upper limit, you can also perform the following operations to achieve the first light chasing:

[0113] Step S1-1, controlling the drying rod to perform a downward movement;

[0114] Step S1-2: collecting the light intensity of the clothes-drying rod at a preset sampling period during the process of the clothes-drying rod descending; collecting N data as a group, averaging the group of data and determining whether it is greater than a first preset value;

[0115] If so, the control rod stops descending, and the stop position is the position when the light intensity of the rod meets the conditions, and the control rod is in this position;

[0116] If not, determine whether the clothes-drying rod is at the bottom position. If so, it means that the data values ​​calculated during the descent of the clothes-drying rod do not meet the preset conditions. At this time, the clothes-drying rod is controlled to rise to the top position and the tracking function is turned off. Otherwise, the clothes-drying rod is controlled to continue to descend and return to step S1-2.

[0117] In this step, the first preset value can be set to 10,000 lux. During the descent of the clothes drying rod, the light intensity of the clothes drying rod can be collected with a sampling period of 100ms. If N is set to 10, each 10 light intensity data collected (N1, N2, N3, ..., N10) are taken as a group, and the data value M is obtained by adding and averaging. After the data value M is calculated, the data value M is compared with the first preset value to determine whether the data value M is greater than the first preset value; if it is greater than the first preset value, the clothes drying machine is immediately controlled to stop descending, so that the clothes drying machine stays at this position.

[0118] The above steps enable this embodiment to make real-time judgments on the light intensity during the descent of the clothes drying rod. When it is detected that the light intensity is greater than the preset value, the clothes drying rod is controlled to stop moving, so that the clothes drying rod stays at a position with relatively high light intensity. Based on this, it is possible to find a drying position that meets the conditions in real time during the descent of the clothes drying rod, ensuring that the clothes drying rod finds a better drying position with the shortest movement distance.

[0119] (2) When the current position of the drying rod is at the bottom position, for example, when the drying rod is at the lower limit position, perform the following operations to achieve the first light tracking:

[0120] Step S2-1, controlling the drying rod to perform an upward movement;

[0121] Step S2-2, collecting the light intensity of the clothes-drying rod at a preset sampling period during the rising process of the clothes-drying rod; as in step S1-2, in this step, collecting the light intensity of the clothes-drying rod at a sampling period of 100ms during the rising process of the clothes-drying rod.

[0122] Step S2-3: For each N data collected, the data value obtained by averaging the data in the group is saved, and a determination is made as to whether the following preset conditions are met: the data value is less than the last saved data value, the last data value is the maximum data value currently saved and is greater than a second preset value;

[0123] If so, the drying rod is controlled to stop, and the stop position is the position when the light intensity of the drying rod meets the conditions, that is, the drying rod is controlled to be in this position;

[0124] If not, it is determined whether the drying rod has reached the top position. If so, it is indicated that the calculated data values ​​during the entire process of the drying rod rising from the bottom to the top do not meet the above preset conditions, so the drying rod is controlled to stay at the top position and the tracking function is turned off; otherwise, the drying rod is controlled to continue rising and the process returns to step S2-2;

[0125] In this embodiment, if N is set to 10, then for every 10 light intensity data points collected (e.g., N1, N2, N3, ..., N10) as a group, the average of N1, N2, N3, ..., N10 is calculated in real time to obtain a data value M, which is then saved in a buffer. In this step, the real-time calculated data value M is determined to be less than the data value Mup last saved in the buffer, and also to be greater than a second preset value. If both are true, it can be determined that M meets the preset conditions, and the control pole is controlled to stop rising. The data value Mup refers to the data calculated by taking the average of the last set of light intensity data collected. Compared to the numerical value M, Mup corresponds to the last data value saved in the buffer. In this embodiment, the second preset value can be set to 10,000 lux.

[0126] Based on the above steps, when the light chasing function is turned on and the clothes drying rod is in the bottom position, when chasing the light for the first time, the clothes drying rod is controlled to move upward and find a position where the current light intensity is less than the last saved data value (the last data value is the currently saved maximum data value and is greater than the preset value) during the rising process. After finding this position, the clothes drying rod is controlled to stop rising, and the stop position is used as a qualified drying position. In this embodiment, due to the lag caused by the transmission, processing, and calculation of light intensity data, when the above position is found, the clothes drying rod may have risen to the next higher position, but because the clothes are below the clothes drying rod, and the actual maximum light intensity is also below the current position of the clothes drying rod, the above steps can make the clothes drying on the clothes drying rod just at the position of maximum light intensity, effectively improving the efficiency of clothes drying. In addition, in this embodiment, the current light intensity being sought is less than the last saved data value and the last data value is the maximum data value. Compared with directly finding the maximum data value, when the clothes drying rod has a section of running positions that are all maximum data values ​​and greater than the second preset value, the above operation can make the clothes drying rod stay at the highest position that meets the light intensity, further improving the clothing drying effect.

[0127] (3) When the current position of the drying rod is in the middle position, that is, between the top position and the bottom position, perform the following operations to achieve the first light tracking:

[0128] Step S3-1, controlling the drying rod to perform a downward movement;

[0129] Step S3-2, collecting the light intensity of the clothes-drying rod at a preset sampling period during the process of the clothes-drying rod descending; as in step S1-2, in this step, collecting the light intensity of the clothes-drying rod at a sampling period of 100ms during the process of the clothes-drying rod descending.

[0130] Step S3-3: collect N data as a group, average the data in the group, and determine whether it is greater than a third preset value;

[0131] If so, the drying rod is controlled to stop, and the stop position is the position when the light intensity of the drying rod meets the conditions, that is, the drying rod is controlled to be in this position;

[0132] If not, determine whether the clothes drying rod is currently at the bottom position; if not, control the clothes drying rod to continue to descend and return to step S3-2; if so, execute step S3-4;

[0133] In this step, if N is 10, each 10 light intensity data collected is a group. In this step, for each group of data, the average value of the 10 light intensity data values ​​is calculated to determine whether the average value is greater than the third preset value. The third preset value can be set to 10000 lux.

[0134] Step S3-4, controlling the drying rod to perform an upward movement;

[0135] Step S3-5, collecting the light intensity of the clothes-drying rod at a preset sampling period during the clothes-drying rod's ascent;

[0136] Step S3-6: Each time N data are collected as a group, the data value calculated after averaging the group of data is saved, and it is determined whether the following preset conditions are met: the data value is less than the last saved data value, the last data value is the maximum data value currently saved and is greater than a second preset value; wherein the second preset value can be set to 10000 lux.

[0137] If so, the control rod stops rising, and the stop position is the position when the light intensity of the rod meets the conditions, that is, the control rod is at this position;

[0138] If not, first determine whether the drying rod has reached the top position; if so, control the drying rod to stay at the top position and turn off the light chasing function; otherwise, control the drying rod to continue rising and return to step S3-5;

[0139] The specific implementation details of this step are as in step S2-3 and will not be repeated here.

[0140] As can be seen from the above steps, during the first light chasing process, when the pole rises from the bottom to the top, if the calculated data values ​​do not meet the preset conditions after real-time determination, and the pole is currently at the top position, the pole is controlled to stay at the top position and the light chasing function is turned off;

[0141] Alternatively, when the current position of the drying rod is between the top position and the bottom position, this embodiment may further perform the following operations to achieve the first light tracking:

[0142] Step S3-1, controlling the drying rod to perform an upward movement;

[0143] Step S3-2: collecting the light intensity of the clothes-drying rod at a preset sampling period during the rising process of the clothes-drying rod; as mentioned above, the preset sampling period in this step can also be set to 100ms.

[0144] Step S3-3: Each time N data are collected as a group, the data value obtained by averaging the group of data is saved, and it is determined whether the following preset conditions are met: the data value is less than the last saved data value, the last data value is the maximum data value currently saved and is greater than a second preset value; wherein the second preset value can be set to 10000 lux, and N is 10.

[0145] If so, the control rod stops rising, and the stop position is the position when the light intensity of the rod meets the conditions, and the control rod is in this position;

[0146] If not, determine whether the clothes drying rod is currently at the top position; if not, control the clothes drying rod to continue to rise and return to step S3-2; if so, execute step S3-4;

[0147] The specific implementation details of this step are as in step S2-3 and will not be repeated here.

[0148] Step S3-4, controlling the drying rod to perform a downward movement;

[0149] Step S3-5, collecting the light intensity of the clothes-drying rod at a preset sampling period during the process of the clothes-drying rod descending;

[0150] Step S3-6: collect N data as a group, average the data in the group and determine whether it is greater than a third preset value. The third preset value can be set to 10,000 lux.

[0151] If so, the control rod stops descending, and the stop position is the position when the light intensity of the rod meets the conditions, and the control rod is in this position;

[0152] If not, first determine whether the drying rod is at the bottom position. If so, finally control the drying rod to the top position and turn off the light chasing function. Otherwise, control the drying rod to continue to descend and return to step S3-5.

[0153] It can be seen from the above steps that during the descent of the clothes-drying rod from the top to the bottom, if the calculated data values ​​are not greater than the third preset value after real-time judgment, it is determined that there is no position in the clothes-drying rod stroke where the light intensity of the clothes-drying rod meets the conditions, so the clothes-drying rod is finally controlled to be in the top position and the chasing light function is turned off.

[0154] In this embodiment, when performing the first light tracking, the number of light sensors can be one or more. When there are multiple light sensors, each data collected with a preset sampling period can be the average value of the light intensity data collected by multiple light sensors at different positions at the same time.

[0155] In this embodiment, after each light chasing function is turned on, the above-mentioned process (1), (2) or (3) is executed according to the position of the clothes drying rod to perform the first light chasing operation. After the clothes drying machine performs the first light chasing operation, the clothes drying rod is stopped at a position where the light intensity is maximum or slightly greater. Considering that the sunlight irradiated on the clothes drying rod will also be offset as the earth rotates, in this embodiment, at least two light sensors arranged along the movement direction of the clothes drying rod can be used to detect and analyze the offset direction of the light. After determining the offset direction, the clothes drying rod is controlled to move up and down to the optimal drying point that meets the conditions, as shown in Figure 3. The specific process is as follows:

[0156] Obtain the light intensity of the clothes-drying pole in real time, and detect the direction of light deviation based on the changes in light intensity;

[0157] When the light is moving upward, perform the following operations:

[0158] S101, controlling the drying rod to perform an upward movement;

[0159] S102. Collect the light intensity of the clothes-drying rod at a preset sampling period during the rising process of the clothes-drying rod. In this embodiment, such as in the first light-chasing operation, the preset sampling period can be set to 100 ms.

[0160] S103: For each N data sets collected, the data value obtained by averaging the data sets is saved, and a determination is made as to whether the following preset conditions are met: the data value is less than the last saved data value, the last data value is the maximum data value currently saved and is greater than a fourth preset value;

[0161] If yes, the drying rod is controlled to stop, and the stop position is the position when the light intensity of the drying rod meets the conditions, and the drying rod is controlled to be in this position;

[0162] If not, it is determined whether the drying rod has risen to the top. If so, the drying rod is controlled to stay at the top position and the light chasing function is turned off. If not, the drying rod is controlled to continue rising and the process returns to step S102.

[0163] When the light is moving downward, perform the following operations:

[0164] S201, controlling the drying rod to perform a downward movement;

[0165] S202, collecting light intensity on the clothes-drying rods at a preset sampling period during the process of the clothes-drying rods being lowered;

[0166] S203, each time collecting N data into a group, taking the average of the group of data and determining whether it is greater than a fifth preset value;

[0167] If yes, the drying rod is controlled to stop, and the stop position is the position when the light intensity of the drying rod meets the conditions, and the drying rod is controlled to be in this position;

[0168] If not, it is determined whether the clothes drying rod is currently at the bottom position; if not, the clothes drying rod is controlled to continue to descend and the process returns to step S202; if so, step S204 is executed;

[0169] S204, controlling the drying rod to perform an upward movement;

[0170] S205, collecting the light intensity of the clothes-drying rod at a preset sampling period during the clothes-drying rod's ascent process;

[0171] S206: For each N data collected, the data value obtained by averaging the data in the group is saved, and a determination is made as to whether the following preset conditions are met: the data value is less than the last saved data value, the last data value is the maximum data value currently saved and is greater than a fourth preset value;

[0172] If so, the control rod stops rising, and the stop position is the position when the light intensity of the rod meets the conditions, and the control rod is in this position;

[0173] If not, determine whether the clothes-drying rod has risen to the top. If so, control the clothes-drying rod to stay at the top position and turn off the light-chasing function. If not, control the clothes-drying rod to continue rising and return to step S205.

[0174] In this embodiment, the fourth preset value and the fifth preset value can both be set to 10,000 lux.

[0175] In this embodiment, the specific process of detecting the light offset direction according to the change in light intensity is as follows:

[0176] Sa. Real-time acquisition of light intensity information on the clothes-drying rod: In this embodiment, the light intensity detected by each light sensor on the clothes-drying rod is acquired. Based on this, the light intensity information on the clothes-drying rod is acquired.

[0177] Sb. When it is detected that the light intensity of the clothes-drying rod at the current moment is less than a preset value, the light intensity of each position in each group of positions on the clothes-drying rod at each moment within a specified time is obtained, that is, the change in the light intensity of the clothes-drying rod is obtained; wherein each position in the same group of positions on the clothes-drying rod is arranged along the direction of movement of the clothes-drying rod, and each position may be located on the same straight line, with the straight line between the positions being perpendicular to the ground, or the horizontal distance between each position is within a specified range. The specified time is the time from the last time the clothes-drying rod stopped to the current moment;

[0178] In this embodiment, light sensors are provided at the locations for obtaining light intensity, and the light sensors detect the light intensity at their respective locations. The current light intensity of the clothes-drying rod can be the average of the current light intensities detected by each light sensor on the clothes-drying rod, or it can be the current light intensity value of one or more light sensors on the clothes-drying rod. In this embodiment, the preset value can be set to 10,000 lux.

[0179] In this embodiment, a light sensor is provided at each position of each group of positions on the clothes-drying rod, that is, the light sensors at each position in the same group of positions are provided along the direction of movement of the clothes-drying rod. In this embodiment, when it is detected that the current light intensity of the clothes-drying rod is less than a preset value, the light intensity L of each position in each group of positions on the clothes-drying rod at each moment in the specified time is obtained. i (k); L i (k) is the light intensity detected at the kth moment at the i-th position in a group of positions on the clothes-drying rod, which can be detected at the kth moment by the light sensor set at the i-th position. k is the kth moment within the specified time, that is, the kth moment between the last stop moment of the clothes-drying rod and the current moment.

[0180] In this embodiment, the light intensity at each position can be detected by one or more light sensors at the position. When detected by multiple light sensors, the light intensity data can be detected by multiple light sensors arranged side by side along the horizontal direction of the clothes-drying pole at the position, and then the light intensity at the position is obtained by averaging. At this time, the position can be considered not as a point position, but as an area position.

[0181] Sc. For each group of positions, determine the sum of the differences in light intensity of the group of positions within the specified time based on the light intensity of each position at each moment within the specified time. The specific process is as follows:

[0182] Sc-1, for each position in each group of positions, calculate the sum of the light intensity differences between the position and the position below it within the specified time:

[0183] Among them, L a(k) is the light intensity detected at time k at position a on the drying rod, L b (k) is the light intensity detected at position b on the drying rod at time k, where k is the kth moment within the specified time, where position b and position a belong to the same group of positions and position b is above position a; SUM b,a It is the sum of the differences in light intensity between position b and position a below it within the specified time.

[0184] In this embodiment, the above calculation can be performed for each position in each group of positions to determine the sum of the light intensity differences between each position and the position below it within a specified time period. Alternatively, the above calculation can be performed for only one or more positions to determine the sum of the light intensity differences between one or more positions and the position below them within a specified time period; the specific calculation is not limited. Furthermore, positions b and a can be adjacent to each other, or they can be non-adjacent, i.e., there are other positions between b and a.

[0185] Sc-2, for each group of positions, average the sum of the light intensity differences calculated above to obtain the sum of the light intensity differences of the group of positions within the specified time;

[0186] In this embodiment, if the sum of the light intensity differences between each position in each group of positions and the position below within the specified time is calculated, and the position below is an adjacent position, then in this embodiment, the sum of the light intensity differences of each group of positions is calculated as:

[0187] Among them, SUM i+1,i L is the sum of the differences in light intensity between the i+1th position and the ith position in the same group of positions on the drying rod within the specified time (i.e., from the 1st moment to the nth moment); i+1 (k) is the light intensity detected at the i+1th position at time k, L i (k) is the light intensity detected at the i-th position at time k; in the direction of the rod's movement, the i+1-th position is above the i-th position and the two are adjacent positions, that is, the light sensor set at the i+1-th position is above the light sensor set at the i-th position; I is the total number of positions in each group of positions on the rod, corresponding to the total number of light sensors arranged in each group of positions along the direction of the rod's movement, and I ≥ 2. SUM x is the sum of the light intensity differences calculated for the x-th group of positions.

[0188] In this embodiment, the sum of the light intensity differences can also be calculated for positions in each group that have a vertical relationship but are not necessarily adjacent. The sum of the calculated light intensity differences is averaged and used as the sum of the light intensity differences for the corresponding group of positions. For example, in a group of positions on the clothes-drying rod, there are four positions from bottom to top, namely positions 1 to 4. For this group of positions, this embodiment can calculate the sum of the light intensity differences between the third position and the first position within a specified time period, SUM 3,1 , the sum of the light intensity differences between the 4th position and the 1st position within the specified time SUM 4,1 , the sum of the light intensity differences between the 4th position and the 3rd position within the specified time SUM 4,3 The sum of the light intensity differences calculated above is added together and averaged to obtain the sum of the light intensity differences of the group of positions within the specified time. In addition, the sum of the light intensity differences of the two adjacent upper and lower positions can also be calculated, including the sum of the light intensity differences of the second position and the first position within the specified time SUM 2,1 , the sum of the light intensity differences between the third position and the second position within the specified time SUM 3,2 , the sum of the light intensity differences between the 4th position and the 3rd position within the specified time SUM 4,3 The sum of the light intensity differences obtained by the above calculations is added together and averaged to obtain the sum of the light intensity differences of the group of positions within the specified time.

[0189] From the above, it can be seen that for each group of positions, when the total difference in light intensity within the specified time is greater than zero, it means that the total light intensity of the upper position is greater than that of the lower position, which generally reflects that the light intensity of the upper position at each moment is greater than that of the lower position; when the total difference in light intensity is less than zero, it means that the total light intensity of the upper position is smaller than that of the lower position, which generally reflects that the light intensity of the lower position at each moment is greater than that of the upper position.

[0190] Sd, the total light intensity difference SUM is obtained based on the sum of the light intensity differences of each group of positions within the specified time.

[0191] When only one group of positions on the drying pole is equipped with a light sensor, that is, when only the light intensity of one group of positions is used, the total light intensity difference SUM is equal to the sum of the light intensity differences of the group of positions within the specified time, that is: SUM=SUM x , x=1;

[0192] When there are multiple groups of light sensors installed on the clothes drying pole, that is, when the light intensity of multiple groups of positions is used, the sum of the light intensity differences of each group of positions within the specified time is averaged to obtain the total light intensity difference SUM:

[0193] Where X is the total number of light sensors, corresponding to the total number of positions on the clothes-drying pole where the light intensity is to be obtained.

[0194] Se, compare the total light intensity difference SUM with the light threshold:

[0195] When SUM>light threshold, it is determined that the light is shifted upward;

[0196] When SUM<-light threshold, it is determined that the light is shifted downward.

[0197] As can be seen from the above, in this embodiment, the pole can be provided with only one set of light sensors arranged along the direction of the pole's movement, or multiple sets of light sensors, each arranged along the direction of the pole's movement. In the latter case, as shown in Figure 4b , the sets of light sensors can be provided at different transverse positions on the pole, with each light sensor in each set arranged along the direction of the pole's movement. The positions of the light sensors in each set on the pole are defined as being in the same group, i.e., positions along the pole's movement. Based on this, the process for determining the direction of light offset in this embodiment is as follows: First, for each set of positions, the sum of the light intensity differences within a specified time period is calculated through steps Sa through Sc described above.

[0198] Then, the sum of the light intensity differences of each group of positions within the specified time is averaged to obtain the total light intensity difference SUM:

[0199] Among them, X is the total number of light sensors, SUM x is the sum of the light intensity differences calculated for the x-th group of positions, that is, based on the x-th group of light sensors.

[0200] Finally, the illumination offset direction is determined based on the total illumination intensity difference SUM obtained by the above calculation.

[0201] In this embodiment, as shown in FIG4a , light sensors are respectively provided at a first position and a second position on the clothes-drying rod, and the two are in the same group of positions. In the direction of movement of the clothes-drying rod, the first position on the clothes-drying rod is located below the second position. Light sensor A is located at the first position, and light sensor B is located at the second position. That is, light sensor A and light sensor B are arranged along the direction of movement of the clothes-drying rod. In this case, the specific process of detecting the light offset direction according to the change in light intensity in this embodiment is as follows:

[0202] Sa1, light sensor A and light sensor B set on the clothes-drying rod obtain light intensity information at a first position and a second position on the clothes-drying rod in real time.

[0203] Sb1. When it is detected that the current light intensity of the clothes-drying rod is less than the preset value, the light intensity of the first position and the second position on the clothes-drying rod at each moment within the specified time is obtained; the above preset value can be set to 10000 lux, and the current light intensity of the clothes-drying rod can be the average of the light intensities detected by light sensor A and light sensor B at the current moment.

[0204] In this embodiment, the light intensity at the first position can be detected by one or more light sensors on the clothes-drying rod. When detected by multiple light sensors, the light intensity data can be detected by multiple light sensors arranged side by side along the horizontal direction of the clothes-drying rod, and the light intensity at the first position can be averaged. Similarly, the light intensity at the second position can be detected by one or more light sensors on the clothes-drying rod. When detected by multiple light sensors, the light intensity data can be detected by multiple light sensors arranged side by side along the horizontal direction of the clothes-drying rod, and the light intensity at the second position can be averaged.

[0205] Sc1. Calculate the sum of the differences in light intensity between the first and second positions on the drying rod within the specified time:

[0206] Among them, L1(k) is the light intensity at the first position of the drying rod at time k, which can be detected by the light sensor A in Figure 4a at time k, and L2(k) is the light intensity at the second position of the drying rod at time k, which can be detected by the light sensor B in Figure 4a at time k; n is the total number of moments within the specified time, that is, the total number of moments from the last stop moment of the drying rod to the current moment. When k=1, L1(1) is the light intensity at the second position of the drying rod at the first moment, that is, the last stop moment; when k=n, L1(n) is the light intensity at the second position of the drying rod at time n, that is, the current moment or the moment before the current moment.

[0207] Sd1, based on the sum of the light intensity differences between the first and second positions on the drying rod within the specified time calculated above, calculate the total light intensity difference SUM:

[0208] In this embodiment, since there is only one group of positions and there are only two positions in the group of positions, the total illumination intensity difference SUM is the sum of the illumination intensity differences of the two positions in the group of positions at a specified time.

[0209] Se1. Compare the total light intensity difference SUM with the light threshold; wherein the light threshold can be set to 3000 to 6000 lux.

[0210] When SUM>light threshold, it is determined that the light is shifted upward;

[0211] When SUM<-light threshold, it is determined that the light is shifted downward.

[0212] In this embodiment, to achieve the continuous light tracking function, at least two light sensors must be used. At least two of these light sensors are arranged along the direction of the pole's movement, so that the direction of light offset can be determined based on changes in the light sensors' illumination of the pole. Specifically, as shown in Figure 4a, light sensor A at a first position and light sensor B at a second position are arranged along the direction of the pole's movement.

[0213] As can be seen from the above, in this embodiment, multiple groups of light sensors can be set at the horizontal position of the clothes-drying rod, that is, the direction of light offset can be determined based on the light intensity of the multiple groups of positions; in each group of light sensors, at least two light sensors are arranged along the direction of movement of the clothes-drying rod, as shown in Figure 4b; based on each group of light sensors, after calculating the sum of the light intensity differences of each group of positions within a specified time through steps Sa to Sc, the average is taken to obtain the total light intensity difference SUM, and the above SUM is compared with the light threshold to determine the direction of light offset. As shown in 4b, two groups of light sensors are set along the horizontal position direction of the clothes-drying rod, and the sum of the light intensity differences SUM is calculated based on the first group of light sensors. 1 , the sum of the light intensity differences SUM is calculated based on the second set of light sensors 2 , for SUM 1 and SUM 2 The total light intensity difference SUM is obtained by averaging, and the total light intensity difference SUM is compared with the light threshold to determine the light offset direction.

[0214] In this embodiment, among the above-mentioned groups of light sensors, one or more groups of sensors may be provided with more than three light sensors, each of which is provided along the direction of movement of the clothes-drying pole (perpendicular to the ground). Based on the light sensors at the upper and lower adjacent positions in each group of light sensors, the total light intensity difference of each group position is calculated through steps Sa to Sd, and then the average is taken to obtain the total light intensity difference SUM, which is compared with the light threshold to determine the direction of light offset. As shown in Figure 4c, one group of light sensors includes three light sensors, namely A, B, and C. Based on the light sensors B and A at the upper and lower adjacent positions, the SUM is calculated. 2,1 , SUM is calculated based on the adjacent light sensors C and B at the upper and lower positions. 3,2 , for SUM 2,1 and SUM 3,2 Take the average to get the sum of the light intensity differences of the group of positions. If there is only one group of light sensors, the sum of the light intensity differences of the group is used as SUM and compared with the light threshold to determine the light offset direction. If there are multiple groups of light sensors, calculate the sum of the light intensity differences of each group SUMx After (x=1, 2, ...X), the total light intensity difference SUM is obtained by averaging, where X is the total number of light sensor groups. The total light intensity difference SUM is compared with the light threshold to determine the light offset direction.

[0215] In this embodiment, as shown in FIG5 , before the above step SA, that is, when the light chasing function is turned off, the light chasing function can be turned on in the following manner:

[0216] First, determine the daytime start time Tstart and end time Tend at the installation location based on the longitude and latitude information of the clothes drying machine installation location; the specific method can be as follows: determine the time zone n (n = 5, 6, 7, 8 and 9) where the longitude of the clothes drying machine installation location is located based on the longitude and latitude information, and determine the daytime start time Tstart = 8 + 9 - n, and the daytime end time Tend = 18 + 9 - n.

[0217] Then, it is determined that the current time T is between the start time point Tstart and the end time point Tend of the day; if so, the light chasing function is turned on.

[0218] In this embodiment, as shown in FIG5 , after the light chasing operation is initiated, the following operation steps are further included: obtaining the light intensity on the clothes drying rod in real time; when it is detected that the light intensity on the clothes drying rod is less than a sixth preset value and the duration exceeds a first threshold, the clothes drying rod is controlled to rise to the top and the light chasing function is disabled. In this embodiment, the sixth preset value can be set to 8000 lux, and the first threshold can be set to 5 minutes. That is, after the first light chasing operation, if the light intensity is detected to be slightly weaker and the duration exceeds the threshold, it can be determined that the current light intensity does not meet the conditions for light chasing. In this case, the clothes drying rod is preferably controlled to rise to the top position and the light chasing function is disabled.

[0219] In this embodiment, when the light-chasing function is off, it can also be enabled in the following manner: real-time monitoring of the light intensity on the clothes-drying poles. When it is detected that the light intensity on the clothes-drying poles is not less than a sixth preset value and the duration exceeds a second threshold, a light-chasing function activation instruction is issued; the second threshold can also be set to 5 minutes. In this embodiment, when the light-chasing function activation instruction is issued, if the current time is between the daytime start time TStart and the daytime end time TEnd, the light-chasing function is activated. Of course, if the daytime start time TStart and the daytime end time TEnd are not considered, the light-chasing function can also be activated directly when the light intensity on the clothes-drying poles is not less than the sixth preset value and the duration exceeds the second threshold.

[0220] In this embodiment, as shown in FIG5 , after the light chasing operation is started, the following steps are further included:

[0221] Real-time monitoring of the weather information at the location where the clothes drying machine is installed. When the weather changes to the first preset weather, the clothes drying rod is controlled to be in the top position and the tracking light function is turned off.

[0222] After the light-tracking function is disabled, the weather information at the location where the clothes drying machine is installed is monitored in real time. When the weather changes to a second preset weather condition, a light-tracking function activation command is issued. In this embodiment, when the light-tracking function activation command is issued, if the current time is between the daytime start time TStart and the daytime end time TEnd, the light-tracking function is activated. Of course, if the daytime start time TStart and the daytime end time TEnd are not considered, the light-tracking function can also be activated directly when the weather changes to the second preset weather condition.

[0223] In this embodiment, the first preset weather may refer to a cloudy day, and the second preset weather may refer to a sunny day. After the clothes drying machine is connected to the Internet, weather information is obtained through the cloud platform. Specifically, the first preset weather and the second preset weather may be set according to the geographical location where the clothes drying machine is installed, etc., to ensure the efficiency of drying clothes.

[0224] In summary, the light chasing control method for clothes drying in this embodiment performs the first light chasing when the light chasing function is turned on and the light chasing conditions are met. Specifically, the optimal drying position is found for the clothes drying rod based on the light intensity information during the lifting and lowering process of the clothes drying rod according to the state of the clothes drying rod when the light chasing function is turned on, so that the clothes drying rod can adaptively perform the first light chasing each time the light chasing function is turned on, so that the clothes drying rod can be in the optimal drying position when the light chasing starts, effectively improving the efficiency of the clothes drying machine. In addition, in the light chasing control method for clothes drying in this embodiment, after the first light chasing, the direction of light offset (including light moving up or down) is further detected based on the collected light intensity changes. When the light moves up or down, the clothes drying rod can be controlled to move up or down so that the clothes drying on the clothes drying rod follow the direction of light movement, so that they are always in the relatively strongest light position, so as to achieve continuous light chasing operation.

[0225] Those skilled in the art will appreciate that all or part of the steps in the method of the present embodiment can be implemented by instructing the relevant hardware through a program, and the corresponding program can be stored in a computer-readable storage medium. It should be noted that although the method operations provided by the present embodiment are described in a specific order in the accompanying drawings, this does not require or imply that these operations must be performed in this specific order, or that all the operations shown must be performed to achieve the desired result. On the contrary, the steps depicted can change the order of execution, some steps can also be performed simultaneously, and additionally or alternatively, some steps can be omitted, multiple steps can be combined into one step for execution, and / or one step can be decomposed into multiple steps for execution.

[0226] The following is a detailed description of a system adapted to the above-mentioned drying and chasing light control method.

[0227] This embodiment discloses a drying and tracking light control system, which is applied to a clothes drying machine. The clothes drying machine includes a main unit and a clothes drying rod. The clothes drying rod is arranged below the main unit through a steel wire rope. The main unit is provided with a main controller, a motor, etc. The main controller is connected to the motor through a motor driver, and the steel wire rope is controlled by the motor to control the lifting and lowering movement to realize the automatic lifting and lowering of the clothes drying rod.

[0228] As shown in FIG6 , the sun drying and light chasing control system in this embodiment includes a controller and a light chasing device, and the light chasing device includes one or more light sensors connected to the controller.

[0229] The light sensor is mounted on the clothes drying rod of the clothes drying machine and is used to detect the light intensity information on the clothes drying rod and transmit the detected light intensity information to the controller. In this embodiment, the light sensor can be an ambient light sensor IC model BH1750FVI, which can measure the light intensity of the ambient light (lumen value lux).

[0230] The controller is used to execute the drying and light tracking control method provided in the embodiment.

[0231] In this embodiment, as shown in FIG7 , the light-chasing device further includes a mounting body 1. A light sensor in the light-chasing device is mounted on the mounting body 1 and is then mounted on the drying pole via the mounting body 1. A raised Fresnel hemispherical lens 2 is embedded in the mounting body. Each light sensor in the light-chasing device is disposed under each raised Fresnel hemispherical lens.

[0232] In this embodiment, when only the first light chasing operation in the drying light chasing control method provided in the embodiment is implemented, only one light sensor can be set on the drying rod, or multiple light sensors can be set. When multiple light sensors are set, the light intensities detected by each light sensor at the same time can be averaged as the final light intensity. Each light sensor can be set along the movement direction of the drying rod, or along the horizontal direction of the drying rod, or include light sensors set in the above directions at the same time. The specific number and position setting method of the light sensors are not required in this embodiment.

[0233] In this embodiment, when it is necessary to simultaneously implement the continuous light-chasing operation in the light-chasing control method for clothes drying provided in the embodiment, at least two light sensors must be installed on the clothes drying rod, and at least two light sensors must be arranged along the direction of movement of the clothes drying rod. The two light sensors are preferably arranged on the same straight line perpendicular to the ground. Of course, it is also feasible for the line connecting the two light sensors to deviate from the straight line perpendicular to the ground within a certain angle range. The specific arrangement can be based on the lighting conditions at the location where the clothes drying machine is installed. In this embodiment, to achieve the continuous light-chasing operation, one or more groups of light sensors can be provided. When there are multiple groups, each group of light sensors can be arranged along the horizontal direction of the clothes drying rod, as shown in Figure 4b;

[0234] Each group of light sensors can include at least two light sensors positioned along the direction of the drying rod's movement. As shown in FIG4c , each sensor group can include three light sensors. Finally, the total light intensity difference SUM is calculated based on the light intensity information detected by the multiple light sensors to determine the direction of the light offset. The specific calculation method and determination principle can be described in the method for controlling the light tracking of clothes in the embodiment and will not be further described here.

[0235] In this embodiment, there is at least one mounting body. If, as described above, there are multiple sets of light sensors, each set of light sensors can be mounted on a corresponding mounting body, and each mounting body can be arranged horizontally along the drying rod. If the system of this embodiment requires continuous light tracking, when there is only one mounting body, at least two light sensors are installed in the mounting body. When the mounting body is installed on the drying rod, at least two light sensors on the mounting body are arranged along the direction of movement of the rod. In this embodiment, the mounting body is attached to the drying rod via magnetic attraction.

[0236] In this embodiment, the above-mentioned controller can be a clothes drying machine main controller or an independently set controller. When it is a clothes drying machine main controller, the light sensor set on the clothes drying rod is connected to the clothes drying machine main controller by wire, and the clothes drying machine main controller implements the light tracking control method provided in the above embodiment. The clothes drying machine main controller can be an MCU.

[0237] In this embodiment, if it is independent of other controllers of the clothes drying machine main controller, the controller can communicate with the clothes drying machine main controller through a wireless communication module or a wired connection. Specifically, when the controller executes the method provided in the above embodiment, it sends the corresponding pole lifting control instruction to the clothes drying machine main controller, and controls the working state of the clothes drying machine motor through the clothes drying machine main controller to realize the pole upgrading control during the light chasing process; In addition, the controller can also be set to only receive the light intensity information sent by the light sensor and send the received light intensity information to the clothes drying machine main controller, and the clothes drying machine main controller implements the method provided in the embodiment. The wireless communication module connected to the above controller can be a Bluetooth module, a WiFi module, a ZigBee module, a radio frequency module, etc. The above controller can also use an MCU.

[0238] As shown in FIG6 , when the controller of this embodiment is an independently set controller, the controller can be set on the clothes-drying rod and connected to the light sensor also set on the clothes-drying rod. When the light-chasing device of this embodiment includes an installation body, the controller can also be set on the installation body.

[0239] In the system of this embodiment, the light-chasing controller may also include a solar panel provided on the clothes drying rod. When the controller is provided independently, the controller is connected to the solar panel, and the controller and the light sensor are powered by the solar panel. For an independently provided controller, when the controller is normally powered, it is generally connected to the clothes drying machine main controller by wired means, and powered by the clothes drying machine input power supply, then the controller and the clothes drying machine main controller can be set to have two-way communication. When the controller is powered by solar panels, the collected light data will only be sent out in one direction when sunlight shines on the solar panel on the controller and can drive the controller normally. At this time, the controller and the clothes drying machine main controller are in one-way communication, that is, the data sent by the clothes drying machine main controller is not received, and the data sent can be received by the clothes drying machine main controller and then the light-chasing control method provided in the embodiment is executed. This can reduce the cost of the controller and does not require additional wired power supply.

[0240] In this embodiment, the controller can be connected to an external terminal and / or cloud platform via a networking module to obtain real-time weather information, network time, longitude and latitude information, etc. The controller can automatically turn on and off the light tracking function based on the weather information, network time, longitude and latitude information, etc. The networking module can be a Wi-Fi module, etc.

[0241] The following is a detailed description of the method for controlling continuous light tracking during drying provided in the embodiment of the present application.

[0242] At present, some of the light-tracking technologies for clothes drying machines are completely dependent on the light-tracking model set in the background. Specifically, the background light-tracking model analyzes and calculates the parameters input in advance by the user and some parameters obtained through the network to obtain the lighting conditions, and then controls the lifting and lowering of the clothes drying machine. Some use light sensors set at fixed positions such as wall-mounted remote controls to detect the lighting conditions to control the lifting and lowering of the clothes drying machine. It is impossible to achieve real-time and continuous light tracking when the light direction shifts.

[0243] Based on the problems existing in the prior art, this embodiment provides a method for controlling continuous light chasing during drying. The method is applied to a clothes drying machine. The clothes drying machine includes a main unit and a clothes drying rod. The clothes drying rod is arranged below the main unit through a steel wire rope. The main unit is provided with a main controller, a motor, a drying module, a lighting module, etc. The controller is connected to the motor through a motor driver, and the steel wire rope is controlled by the motor to realize the automatic lifting of the clothes drying rod. The continuous light chasing control method of this embodiment can be implemented by a control system provided on the clothes drying machine. The control system is connected to a light sensor provided on the clothes drying rod. The control system can be directly the main controller in the clothes drying machine main unit, or it can be a separate controller. As shown in Figure 8, the continuous light chasing control method for drying includes:

[0244] SA, obtain the light intensity information of the clothes drying rack, determine the change of the light intensity of the clothes drying rack, and determine the light offset direction according to the change of the light intensity of the clothes drying rack.

[0245] In this embodiment, at least two light sensors are provided on the clothes drying rod of the clothes drying machine and are arranged along the movement direction of the clothes drying rod. Based on the light intensity detected by each light sensor at different times, the change in light intensity, that is, the light condition at the position where each light sensor is set, can be determined, thereby determining the direction of light offset.

[0246] SB. Control the pole to move up and down according to the direction of light offset, collect the light intensity during the pole's lifting process, and determine the position of the pole when the light intensity meets the conditions.

[0247] SC, control the drying rod to be at the position determined above.

[0248] In this embodiment, in the above step SA, the specific process of determining the light offset direction is as follows:

[0249] Sa. Real-time acquisition of light intensity information on the clothes-drying rod: In this embodiment, the light intensity detected by each light sensor on the clothes-drying rod is acquired. Based on this, the light intensity information on the clothes-drying rod is acquired.

[0250] Sb. When it is detected that the light intensity of the clothes-drying rod at the current moment is less than a preset value, the light intensity of each position in each group of positions on the clothes-drying rod at each moment within a specified time is obtained, that is, the change in the light intensity of the clothes-drying rod is obtained; wherein each position in the same group of positions on the clothes-drying rod is arranged along the direction of movement of the clothes-drying rod, and each position may be located on the same straight line, with the straight line between the positions being perpendicular to the ground, or the horizontal distance between each position is within a specified range. The specified time is the time from the last time the clothes-drying rod stopped to the current moment;

[0251] In this embodiment, light sensors are provided at the locations for obtaining light intensity, and the light sensors detect the light intensity at their respective locations. The current light intensity of the clothes-drying rod can be the average of the current light intensities detected by each light sensor on the clothes-drying rod, or it can be the current light intensity value of one or more light sensors on the clothes-drying rod. In this embodiment, the preset value can be set to 10,000 lux.

[0252] In this embodiment, a light sensor is provided at each position of each group of positions on the clothes-drying rod, that is, the light sensors at each position in the same group of positions are provided along the direction of movement of the clothes-drying rod. In this embodiment, when it is detected that the current light intensity of the clothes-drying rod is less than a preset value, the light intensity L of each position in each group of positions on the clothes-drying rod at each moment in the specified time is obtained. i (k); L i(k) is the light intensity detected at the kth moment at the i-th position in the same group of positions on the clothes-drying rod, which can be detected at the kth moment by the light sensor set at the i-th position. k is the kth moment within the specified time, that is, the kth moment between the last stop moment of the clothes-drying rod and the current moment.

[0253] In this embodiment, the light intensity at each position can be detected by one or more light sensors at the position. When detected by multiple light sensors, the light intensity data can be detected by multiple light sensors arranged side by side along the horizontal direction of the clothes-drying pole at the position, and then the light intensity at the position is obtained by averaging. At this time, the position can be considered not as a point position, but as an area position.

[0254] Sc. For each group of positions, determine the sum of the differences in light intensity of the group of positions within the specified time based on the light intensity of each position at each moment within the specified time. The specific process is as follows:

[0255] Sc-1, for each position in each group of positions, calculate the sum of the light intensity differences between the position and the position below it within the specified time:

[0256] Among them, L a (k) is the light intensity detected at time k at position a on the drying rod, L b (k) is the light intensity detected at position b on the drying rod at time k, where k is the kth moment within the specified time, where position b and position a belong to the same group of positions and position b is above position a; SUM b,a It is the sum of the differences in light intensity between position b and position a below it within the specified time.

[0257] In this embodiment, the above calculation can be performed for each position in each group of positions to determine the sum of the light intensity differences between each position and the position below it within a specified time period. Alternatively, the above calculation can be performed for only one or more positions to determine the sum of the light intensity differences between one or more positions and the position below them within a specified time period; the specific calculation is not limited. Furthermore, positions b and a can be adjacent to each other, or they can be non-adjacent, i.e., there are other positions between b and a.

[0258] Sc-2, for each group of positions, average the sum of the light intensity differences calculated above to obtain the sum of the light intensity differences of the group of positions within the specified time;

[0259] In this embodiment, if the sum of the light intensity differences between each position in each group of positions and the position below within the specified time is calculated, and the position below is an adjacent position, then in this embodiment, the sum of the light intensity differences of each group of positions is calculated as:

[0260] Among them, SUM i+1,i SUM is the sum of the differences in light intensity between the i+1th position and the ith position in the same group on the drying rod during a specified time period (i.e., from time 1 to time n). In the direction of the rod's movement, the i+1th position is above the ith position, and the two are adjacent positions. This means that the light sensor at the i+1th position is above the light sensor at the ith position. I is the total number of positions in each group on the drying rod, corresponding to the total number of light sensors arranged in each group along the rod's movement direction. I ≥ 2. x The sum of the light intensity differences calculated for the x-th group of positions.

[0261] In this embodiment, the sum of the light intensity differences can also be calculated for positions in each group that have a vertical relationship but are not necessarily adjacent. The sum of the calculated light intensity differences is averaged and used as the sum of the light intensity differences for the corresponding group of positions. For example, in a group of positions on the clothes-drying rod, there are four positions from bottom to top, namely positions 1 to 4. For this group of positions, this embodiment can calculate the sum of the light intensity differences between the third position and the first position within the specified time SUM 3,1 , the sum of the light intensity differences between the 4th position and the 1st position within the specified time SUM 4,1 , the sum of the light intensity differences between the 4th position and the 3rd position within the specified time SUM 4,3 The sum of the light intensity differences calculated above is added together and averaged to obtain the sum of the light intensity differences of the group of positions within the specified time. In addition, the sum of the light intensity differences of the two adjacent upper and lower positions can also be calculated, including the sum of the light intensity differences of the second position and the first position within the specified time SUM 2,1 , the sum of the light intensity differences between the third position and the second position within the specified time SUM 3,2 , the sum of the light intensity differences between the 4th position and the 3rd position within the specified time SUM 4,3 The sum of the light intensity differences obtained by the above calculations is added together and averaged to obtain the sum of the light intensity differences of the group of positions within the specified time.

[0262] From the above, it can be seen that for each group of positions, when the total difference in light intensity within the specified time is greater than zero, it means that the total light intensity of the upper position is greater than that of the lower position, which generally reflects that the light intensity of the upper position at each moment is greater than that of the lower position; when the total difference in light intensity is less than zero, it means that the total light intensity of the upper position is smaller than that of the lower position, which generally reflects that the light intensity of the lower position at each moment is greater than that of the upper position.

[0263] Sd, the total light intensity difference SUM is obtained based on the sum of the light intensity differences of each group of positions within the specified time.

[0264] When only one group of positions on the drying pole is equipped with a light sensor, that is, when only the light intensity of one group of positions is used, the total light intensity difference SUM is equal to the sum of the light intensity differences of the group of positions within the specified time, that is: SUM=SUM x , x=1;

[0265] When there are multiple groups of light sensors installed on the clothes drying pole, that is, when the light intensity of multiple groups of positions is used, the sum of the light intensity differences of each group of positions within the specified time is averaged to obtain the total light intensity difference SUM:

[0266] Where X is the total number of light sensors, corresponding to the total number of positions on the clothes-drying pole where the light intensity is to be obtained.

[0267] Se, compare the total light intensity difference SUM with the light threshold:

[0268] When SUM>light threshold, it is determined that the light is shifted upward;

[0269] When SUM<-light threshold, it is determined that the light is shifted downward.

[0270] As can be seen from the above, in this embodiment, the pole can be provided with only one set of light sensors arranged along the direction of the pole's movement, or multiple sets of light sensors, each arranged along the direction of the pole's movement. In the latter case, as shown in Figure 4b , the sets of light sensors can be provided at different transverse positions on the pole, with each light sensor in each set arranged along the direction of the pole's movement. The positions of the light sensors in each set on the pole are defined as being in the same group, i.e., positions along the pole's movement. Based on this, the process for determining the direction of light offset in this embodiment is as follows: First, for each set of positions, the sum of the light intensity differences within a specified time period is calculated through steps Sa through Sc described above.

[0271] Then, the sum of the light intensity differences of each group of positions within the specified time is averaged to obtain the total light intensity difference SUM:

[0272] Among them, X is the total number of light sensors, SUM x is the sum of the light intensity differences calculated for the x-th group of positions, that is, based on the x-th group of light sensors.

[0273] Finally, the illumination offset direction is determined based on the total illumination intensity difference SUM obtained by the above calculation.

[0274] In this embodiment, as shown in FIG4a , light sensors are respectively provided at a first position and a second position on the clothes-drying rod, and the two are in the same group of positions. In the direction of movement of the clothes-drying rod, the first position on the clothes-drying rod is located below the second position. Light sensor A is located at the first position, and light sensor B is located at the second position. That is, light sensor A and light sensor B are arranged along the direction of movement of the clothes-drying rod. In this case, the specific process of detecting the light offset direction according to the change in light intensity in this embodiment is as follows:

[0275] Sa1, light sensor A and light sensor B set on the clothes-drying rod obtain light intensity information at a first position and a second position on the clothes-drying rod in real time.

[0276] Sb1. When it is detected that the current light intensity of the clothes-drying rod is less than the preset value, the light intensity of the first position and the second position on the clothes-drying rod at each moment within the specified time is obtained; the above preset value can be set to 10000 lux, and the current light intensity of the clothes-drying rod can be the average of the light intensities detected by light sensor A and light sensor B at the current moment.

[0277] In this embodiment, the light intensity at the first position can be detected by one or more light sensors on the clothes-drying rod. When detected by multiple light sensors, the light intensity data can be detected by multiple light sensors arranged side by side along the horizontal direction of the clothes-drying rod, and the light intensity at the first position can be averaged. Similarly, the light intensity at the second position can be detected by one or more light sensors on the clothes-drying rod. When detected by multiple light sensors, the light intensity data can be detected by multiple light sensors arranged side by side along the horizontal direction of the clothes-drying rod, and the light intensity at the second position can be averaged.

[0278] Sc1. Calculate the sum of the differences in light intensity between the first and second positions on the drying rod within the specified time:

[0279] Among them, L1(k) is the light intensity at the first position of the drying rod at time k, which can be detected by the light sensor A in Figure 4a at time k, and L2(k) is the light intensity at the second position of the drying rod at time k, which can be detected by the light sensor B in Figure 4a at time k; n is the total number of moments within the specified time, that is, the total number of moments from the last stop moment of the drying rod to the current moment. When k=1, L1(1) is the light intensity at the second position of the drying rod at the first moment, that is, the last stop moment; when k=n, L1(n) is the light intensity at the second position of the drying rod at time n, that is, the current moment or the moment before the current moment.

[0280] Sd1, based on the sum of the light intensity differences between the first and second positions on the drying rod within the specified time calculated above, calculate the total light intensity difference SUM:

[0281] In this embodiment, since there is only one group of positions and there are only two positions in the group of positions, the total illumination intensity difference SUM is the sum of the illumination intensity differences of the two positions in the group of positions at a specified time.

[0282] Se1. Compare the total light intensity difference SUM with the light threshold; wherein the light threshold can be set to 3000 lux to 6000 lux.

[0283] When SUM>light threshold, it is determined that the light is shifted upward;

[0284] When SUM<-light threshold, it is determined that the light is shifted downward.

[0285] In this embodiment, to achieve the continuous light tracking function, at least two light sensors must be used. At least two of these light sensors are arranged along the direction of the pole's movement, so that the direction of light offset can be determined based on changes in the light sensors' illumination of the pole. Specifically, as shown in Figure 4a, light sensor A at a first position and light sensor B at a second position are arranged along the direction of the pole's movement.

[0286] As can be seen from the above, in this embodiment, multiple groups of light sensors can be set at the horizontal position of the clothes-drying rod, that is, the direction of light offset is determined based on the light intensity of the multiple groups of positions; in each group of light sensors, at least two light sensors are arranged along the direction of movement of the clothes-drying rod, as shown in Figure 4b; based on each group of light sensors, after calculating the sum of the light intensity differences of each group of positions within the specified time through steps Sa~Sc, the average is taken to obtain the total light intensity difference SUM, and the above SUM is compared with the light threshold to determine the direction of light offset. As shown in Figure 4b, two groups of light sensors are set along the horizontal position direction of the clothes-drying rod, and the sum of the light intensity differences SUM is calculated based on the first group of light sensors. 1 , the sum of the light intensity differences SUM is calculated based on the second set of light sensors 2 , for SUM 1 and SUM 2 The total light intensity difference SUM is obtained by averaging, and the total light intensity difference SUM is compared with the light threshold to determine the light offset direction.

[0287] In this embodiment, among the above-mentioned groups of light sensors, one or more groups of sensors may be provided with more than three light sensors, each of which is provided along the direction of movement of the clothes-drying pole (perpendicular to the ground). Based on the light sensors at the upper and lower adjacent positions in each group of light sensors, the total light intensity difference of each group position is calculated through steps Sa to Sd, and then the average is taken to obtain the total light intensity difference SUM, which is compared with the light threshold to determine the direction of light offset. As shown in Figure 4c, one group of light sensors includes three light sensors, namely A, B, and C. Based on the light sensors B and A at the upper and lower adjacent positions, the SUM is calculated. 2,1 , SUM is calculated based on the adjacent light sensors C and B at the upper and lower positions. 3,2 , for SUM 2,1 and SUM 3,2 Take the average to get the sum of the light intensity differences of the group of positions. If there is only one group of light sensors, the sum of the light intensity differences of the group is used as SUM and compared with the light threshold to determine the light offset direction. If there are multiple groups of light sensors, calculate the sum of the light intensity differences of each group SUM x (x=1, 2, ...X), take the average to obtain the total light intensity difference SUM, where X is the total number of light sensor groups. The total light intensity difference SUM is compared with the light threshold to determine the light offset direction.

[0288] In this embodiment, in the above step SB, the clothes-drying rod is controlled to move up and down in a predetermined direction according to the light offset direction, and the light intensity during the process of the clothes-drying rod being raised and lowered in the predetermined direction is collected to determine the position of the clothes-drying rod when the light intensity meets the conditions. The specific process is as follows:

[0289] (1) When the light offset direction is upward, perform the following operations:

[0290] S101, controlling the clothes drying rod to perform an upward movement.

[0291] S102. Collect the light intensity of the clothes-drying rod at a preset sampling period during the clothes-drying rod's rising process. In this step, collect the light intensity of the clothes-drying rod at a sampling period of 100 ms during the clothes-drying rod's rising process.

[0292] S103: For each N data sets collected, the data value obtained by averaging the data sets is saved, and a determination is made as to whether the following preset conditions are met: the data value is less than the last saved data value, and the last data value is the maximum data value currently saved and greater than a first preset value;

[0293] If yes, the drying rod is controlled to stop, and the stop position is the position when the light intensity of the drying rod meets the conditions, and the drying rod is controlled to be in this position;

[0294] If not, it is determined whether the drying rod has risen to the top. If so, the drying rod is controlled to stay at the top position and the light chasing function is turned off. If not, the drying rod is controlled to continue rising and the process returns to step S102.

[0295] In this embodiment, if N is set to 10, then for every 10 light intensity data points collected (e.g., N1, N2, N3, ..., N10) as a group, the average of N1, N2, N3, ..., N10 is calculated in real time to obtain a data value M, which is then saved in a buffer. In this step, the real-time calculated data value M is determined to be less than the data value Mup last saved in the buffer, and also to determine whether Mup is the currently saved maximum data value and greater than a first preset value. If both are true, it can be determined that M meets the preset conditions, and the control pole is controlled to stop rising. The data value Mup refers to the data calculated by taking the average of the last set of light intensity data collected. Compared to the numerical value M, Mup corresponds to the last data value saved in the buffer. In this embodiment, the first preset value can be set to 10,000 lux.

[0296] In this embodiment, when the light shifts upward, the clothes drying rod is controlled to move upward, and the optimal drying position is found during the upward movement. This operation, i.e., controlling the clothes drying rod to stop when it is detected that the light intensity at the clothes drying rod position is reduced and the light intensity at the previous position is at maximum light intensity, effectively utilizes the hysteresis of receiving light sensor information, so that the clothes on the clothes drying rod are exactly in the drying position with maximum light intensity when the clothes drying rod stops, effectively improving the drying efficiency. In addition, based on this embodiment, the current light intensity found during the clothes drying rod's upward movement satisfies the requirement of being less than the last stored data value and the last data value being the maximum data value. Compared to directly finding the maximum data value, when the clothes drying rod has a period of operating positions with the maximum data value and greater than a first preset value, this operation can cause the clothes drying rod to stay at the position that satisfies the highest light intensity, further improving the clothes drying effect.

[0297] (2) When the light offset direction is downward, perform the following operations:

[0298] S201, controlling the drying rod to perform a downward movement;

[0299] S202. Collect the light intensity of the clothes-drying rod at a preset sampling period during the process of the clothes-drying rod being lowered. In this step, collect the light intensity of the clothes-drying rod at a sampling period of 100 ms during the process of the clothes-drying rod being lowered.

[0300] S203, each time collecting N data into a group, taking the average of the group of data and determining whether it is greater than a second preset value;

[0301] If so, the control rod stops descending, and the stop position is the position when the light intensity of the rod meets the conditions, and the control rod is in this position;

[0302] If not, it is determined whether the clothes drying rod is currently at the bottom position; if not, the clothes drying rod is controlled to continue to descend and the process returns to step S202; if so, step S204 is executed;

[0303] The second preset value in this step can be set to 10000 lux. During the descent of the clothes drying rod, the light intensity of the clothes drying rod can be collected with a sampling period of 100ms. If N is set to 10, each 10 light intensity data collected (N1, N2, N3, ..., N10) are taken as a group, and the average value is taken after adding them up to obtain the data value M. After the data value M is calculated, the data value M is compared with the second preset value to determine whether the data value M is greater than the second preset value; if it is greater than the second preset value, the clothes drying machine is immediately controlled to stop descending, so that the clothes drying machine stays at this position.

[0304] S204, controlling the drying rod to perform an upward movement.

[0305] S205. Collect the light intensity of the clothes-drying rod at a preset sampling period during the clothes-drying rod's rising process, wherein the preset sampling period can be set to 100 ms.

[0306] S206: For each N data sets collected, the data value obtained by averaging the data sets is saved, and a determination is made as to whether the following preset conditions are met: the data value is less than the last saved data value, and the last data value is the maximum data value currently saved and greater than a first preset value;

[0307] If so, the control rod stops rising, and the stop position is the position when the light intensity of the rod meets the conditions, and the control rod is in this position;

[0308] If not, determine whether the clothes-drying rod has risen to the top. If so, control the clothes-drying rod to stay at the top position and turn off the light-chasing function. If not, control the clothes-drying rod to continue rising and return to step S205.

[0309] The specific implementation details of step S206 are the same as those of step 103 and will not be repeated here.

[0310] In this embodiment, when the direction of light offset is downward, the clothes drying rod is first controlled to descend, and the optimal drying position that meets the conditions is found during the descent process, that is, a position greater than a second preset value. If the optimal drying position that meets the conditions cannot be found during the descent process, the clothes drying rod is controlled to rise again after it descends to the bottom, so as to find the optimal drying position that meets the conditions during the rising process. If it is still not found, the clothes drying rod is controlled to stay at the top position and the light chasing function is turned off. Through the continuous light chasing method of this embodiment, the clothes drying rod can always be kept in the optimal drying position, effectively improving the drying efficiency.

[0311] In this embodiment, as shown in FIG9 , the light chasing function can be enabled in the following manner so that the drying rod enters a continuous light chasing operation:

[0312] First, determine the daytime start time Tstart and end time Tend at the installation location based on the longitude and latitude information of the clothes drying machine installation location; the specific method can be as follows: determine the time zone n (n = 5, 6, 7, 8 and 9) where the longitude of the clothes drying machine installation location is located based on the longitude and latitude information, and determine the daytime start time Tstart = 8 + 9 - n, and the daytime end time Tend = 18 + 9 - n.

[0313] Then, it is determined that the current time T is between the start time point Tstart and the end time point Tend of the day; if so, the light chasing function is turned on.

[0314] In this embodiment, during the continuous light chasing process, as shown in FIG9 , the following operation steps are further included: obtaining the light intensity of the clothes-drying rod in real time; when it is detected that the light intensity of the clothes-drying rod is less than a third preset value and the duration exceeds a first threshold, controlling the clothes-drying rod to rise to the top and disabling the light chasing function; in this embodiment, the third preset value can be set to 8000 lux, and the first threshold can be set to 5 minutes. That is, after the first light chasing, if the light intensity is detected to be slightly weaker and the duration exceeds the threshold, it can be determined that the current light intensity does not meet the conditions for light chasing, and in this case, the clothes-drying rod is preferably controlled to rise to the top position and the light chasing function is disabled.

[0315] In this embodiment, when the light-chasing function is off, as shown in FIG9 , the light-chasing function can also be enabled in the following manner: real-time monitoring of the light intensity on the clothes-drying poles. When the light intensity on the clothes-drying poles is detected to be no less than a third preset value and the duration exceeds a second threshold, a light-chasing function activation instruction is issued; the second threshold can also be set to 5 minutes. In this embodiment, after the light-chasing function activation instruction is issued, if the current time is between the daytime start time TStart and the daytime end time TEnd, the light-chasing function is activated. Of course, if the daytime start time TStart and the daytime end time TEnd are not considered, the light-chasing function can also be activated directly when the light intensity on the clothes-drying poles is no less than the third preset value and the duration exceeds the second threshold.

[0316] In this embodiment, the continuous light chasing process further includes the following steps:

[0317] Real-time monitoring of the weather information at the location where the clothes drying machine is installed. When the weather changes to the first preset weather, the clothes drying rod is controlled to be in the top position and the tracking light function is turned off.

[0318] After the light-tracking function is disabled, the weather information at the location where the clothes drying machine is installed is monitored in real time. When the weather changes to a second preset weather condition, a light-tracking function activation command is issued. In this embodiment, when the light-tracking function activation command is issued, if the current time is between the daytime start time TStart and the daytime end time TEnd, the light-tracking function is activated. Of course, if the daytime start time TStart and the daytime end time TEnd are not considered, the light-tracking function can also be activated directly when the weather changes to the second preset weather condition.

[0319] In this embodiment, the first preset weather may refer to a cloudy day, and the second preset weather may refer to a sunny day. After the clothes drying machine is connected to the Internet, weather information is obtained through the cloud platform. Specifically, the first preset weather and the second preset weather may be set according to the geographical location where the clothes drying machine is installed, etc., to ensure the efficiency of drying clothes.

[0320] In summary, the continuous light tracking control method for drying clothes in this embodiment determines the light change based on the light intensity on the clothes drying rod during the clothes drying process, and further determines the light offset direction. When the light offsets upward, the clothes drying rod is controlled to move upward to a position that meets the light conditions, that is, the optimal drying position. When the light offsets downward, the clothes drying rod is first controlled to move downward to find a position that meets the conditions. If the search is unsuccessful, the clothes drying rod is controlled to rise and find a position that meets the conditions during the rising process. Based on this, the method of this embodiment can continuously track the changing light in the drying area based on the real-time offset light, so that the clothes drying on the clothes drying rod can always be in the optimal drying position, effectively improving the efficiency of the clothes drying machine.

[0321] Those skilled in the art will appreciate that all or part of the steps in the method of this embodiment can be implemented by instructing the relevant hardware through a program, and the corresponding program can be stored in a computer-readable storage medium. It should be noted that although the operations of the method for controlling the continuous light chasing during drying provided by this embodiment are described in a specific order in the accompanying drawings, this does not require or imply that these operations must be performed in this specific order, or that all the operations shown must be performed to achieve the desired results. On the contrary, the steps depicted can change the order of execution, some steps can also be performed simultaneously, and additionally or alternatively, certain steps can be omitted, multiple steps can be combined into one step, and / or one step can be decomposed into multiple steps.

[0322] The following is a detailed description of a system suitable for a method of controlling continuous light tracking during drying.

[0323] This embodiment discloses a continuous light tracking control system for drying clothes, which is applied to a clothes drying machine. The clothes drying machine includes a main unit and a clothes drying rod. The clothes drying rod is arranged below the main unit through a steel wire rope. The main unit is provided with a main controller, a motor, etc. The main controller is connected to the motor through a motor driver, and the steel wire rope is controlled by the motor to control the lifting and lowering movement, thereby realizing automatic lifting and lowering of the clothes drying rod.

[0324] As shown in FIG6 , the continuous light tracking control system for drying clothes in this embodiment includes a controller and a light tracking device, wherein the light tracking device includes a plurality of light sensors connected to the controller.

[0325] Each light sensor is mounted on the clothes drying rod of the clothes drying machine and is used to monitor the light intensity on the rod in real time and transmit the information to the controller. In this embodiment, to determine the direction of light deviation, at least two light sensors must be installed on the clothes drying rod. In this embodiment, the light sensor can be an ambient light sensor IC model BH1750FVI, which can measure the ambient light intensity (lumens value lux).

[0326] A controller is used to execute the method for controlling continuous light tracking during drying provided in the embodiment; wherein the controller is directly or indirectly connected to the motion drive mechanism of the drying rod, and is used to control the movement of the drying rod based on the light offset direction.

[0327] In this embodiment, one or more groups of light sensors may be provided on the clothes-drying rod. When it is necessary to obtain light intensity information for a group of positions on the clothes-drying rod, a light sensor may be provided at each position within the group. As shown in the method provided in the embodiment, each position within the group is along the direction of movement of the clothes-drying rod, and therefore the light sensors at each position are also provided along the direction of movement of the clothes-drying rod. When it is necessary to obtain light intensity information for multiple groups of positions on the clothes-drying rod and determine the direction of light offset based on the light intensity information from the multiple groups of positions, a corresponding group of light sensors may be provided at each group of positions.

[0328] When there are multiple groups of light sensors, each group of light sensors can be set along the horizontal direction of the clothes-drying rod, as shown in Figure 4b; one or more groups of light sensors are set with at least two light sensors set along the direction of movement of the clothes-drying rod, as shown in Figure 4c, each group of sensors includes 3 light sensors, and the 3 light sensors are set along the direction of movement of the clothes-drying rod. Finally, the total difference in light intensity SUM can be calculated based on the light intensity information detected by the multiple groups of light sensors to determine the direction of light offset. The specific calculation method and determination principle can be as shown in the method provided in the embodiment, and will not be repeated here. Among them, the light sensors set along the direction of movement of the clothes-drying rod in the same group can be sensors set on the same vertical line on the ground, as shown in Figures 4a to 4c; or they can be sensors with a horizontal distance within a certain range and set along the direction of movement of the clothes-drying rod, that is, in the up and down direction, as shown in Figure 4d. They can be set specifically according to the light conditions of the installation location of the clothes-drying machine.

[0329] In this embodiment, as shown in Figure 7, the light-chasing device further includes a mounting body 1. A light sensor in the light-chasing device is mounted on the mounting body 1 and is then mounted on the clothes-drying pole via the mounting body 1. A raised Fresnel hemispherical lens 2 is embedded in the mounting body. Each light sensor in the light-chasing device is positioned below a corresponding raised Fresnel hemispherical lens. The mounting body can be attached to the clothes-drying pole via magnetic attraction.

[0330] In this embodiment, to determine the direction of light deviation, at least two light sensors can be installed on the same mounting body. As shown in Figure 7, after the mounting body is attached to the clothes-drying rod, the at least two light sensors on the mounting body are positioned along the direction of the rod's movement. Alternatively, only one light sensor can be installed on the mounting body, in which case at least two mounting bodies are required, positioned along the direction of the rod's movement. If multiple sets of light sensors are provided, each set of light sensors can be installed on a corresponding mounting body, with each mounting body arranged transversely along the clothes-drying rod.

[0331] In this embodiment, the controller can be a clothes drying machine main controller or an independently set controller. When it is a clothes drying machine main controller, the light sensor set on the clothes drying rod is connected to the clothes drying machine main controller by wire, and the clothes drying machine main controller implements the light tracking control method provided in the above embodiment. The clothes drying machine main controller can be an MCU. The controller is directly or indirectly connected to the motion mechanism of the clothes drying rod, which means that when the controller is a clothes drying machine main controller, the controller is directly connected to the motion drive mechanism of the clothes drying rod and directly sends corresponding control instructions to the motion drive mechanism of the clothes drying rod to control the movement of the clothes drying rod. When the controller is an independently set controller, the controller is indirectly connected to the motion drive mechanism of the clothes drying rod, that is, there is no direct connection between the controller and the motion drive mechanism of the clothes drying rod, and the control needs to be achieved through the clothes drying rod main controller.

[0332] In this embodiment, if it is independent of other controllers of the clothes drying machine main controller, the controller can communicate with the clothes drying machine main controller through a wireless communication module or a wired connection. Specifically, when the controller executes the method provided in the above embodiment, it sends the corresponding pole lifting control instruction to the clothes drying machine main controller, and controls the working state of the clothes drying machine motor through the clothes drying machine main controller to realize the pole upgrading control during the light chasing process; In addition, the controller can also be set to only receive the light intensity information sent by the light sensor and send the received light intensity information to the clothes drying machine main controller, and the clothes drying machine main controller implements the method provided in the embodiment. The wireless communication module connected to the above controller can be a Bluetooth module, a WiFi module, a ZigBee module, a radio frequency module, etc. The above controller can also use an MCU.

[0333] As shown in FIG6 , when the controller of this embodiment is an independently set controller, the controller can be set on the clothes-drying rod and connected to the light sensor also set on the clothes-drying rod. When the light-chasing device of this embodiment includes an installation body, the controller can also be set on the installation body.

[0334] In the system of this embodiment, the light-chasing controller may also include a solar panel provided on the clothes drying rod. When the controller is provided independently, the controller is connected to the solar panel, and the controller and the light sensor are powered by the solar panel. For an independently provided controller, when the controller is normally powered, it is generally connected to the clothes drying machine main controller by wired means, and powered by the clothes drying machine input power supply, then the controller and the clothes drying machine main controller can be set to have two-way communication. When the controller is powered by solar panels, the collected light data will only be sent out in one direction when sunlight shines on the solar panel on the controller and can drive the controller normally. At this time, the controller and the clothes drying machine main controller are in one-way communication, that is, the data sent by the clothes drying machine main controller is not received, and the data sent can be received by the clothes drying machine main controller and then the light-chasing control method provided in the embodiment is executed. This can reduce the cost of the controller and does not require additional wired power supply.

[0335] In this embodiment, the controller can be connected to an external terminal and / or cloud platform via a networking module to obtain real-time weather information, network time, longitude and latitude information, etc. The controller can automatically turn on and off the light tracking function based on the weather information, network time, longitude and latitude information, etc. The networking module can be a Wi-Fi module, etc.

[0336] The following is a detailed description of the light chasing and drying control method provided in the embodiment of the present application.

[0337] The embodiment of the present application provides a method for controlling sun drying, as shown in FIG10 , the method comprising:

[0338] Step SA: obtaining the current drying condition information of the clothes drying machine when the light chasing function is turned on, and determining whether the light chasing condition is met according to the current drying condition information.

[0339] For this embodiment, the clothes drying machine has a light-tracking function. When the light-tracking function of the clothes drying machine is turned on and the current drying condition information meets the light-tracking conditions, the clothes drying machine can automatically adjust the drying position of the clothes according to the difference in sunlight intensity at different drying positions, so that the clothes are always in a drying position with appropriate light intensity. The drying position with appropriate light intensity can be the best drying position with the strongest light.

[0340] The light-chasing conditions can be pre-set by the clothes dryer's factory defaults and / or user-defined. These light-chasing conditions define the current drying conditions for which the clothes dryer can effectively chase the light. If the current drying conditions do not meet the light-chasing conditions, even if the light-chasing operation is performed, it will be ineffective and the clothes will not be placed in the optimal drying position for light intensity. By only initiating the light-chasing operation when the clothes dryer's current drying conditions meet the light-chasing conditions, energy consumption caused by ineffective light-chasing can be avoided, improving the efficiency and intelligence of light-chasing drying.

[0341] The current drying condition information includes at least one of the installation location, installation direction, drying date, current time point, daytime period, weather information and light intensity.

[0342] The installation location is specifically the positioning information of the installation point of the clothes drying machine, that is, the longitude and latitude information.

[0343] The installation orientation specifically refers to the orientation of the clothes drying machine based on a predetermined component after installation, for example, the orientation of the clothes drying machine based on the length direction of the clothes drying rod after installation.

[0344] The drying date is specifically the date of the drying day, and the date can be a public date or a lunar date.

[0345] The current time point is specifically the time point of the current moment, and the time point can be accurate to hours, minutes or seconds according to application requirements.

[0346] The daytime time period is specifically the time period between the daytime start time and the end time of the clothes drying day. The daytime start time and the end time of the clothes drying day can be determined based on the latitude and longitude information of the clothes drying machine installation point via the Internet.

[0347] The weather information specifically refers to the weather conditions at the current moment, such as the probability of rainfall, probability of sunny days, temperature and humidity, etc.

[0348] The light intensity is specifically the sunlight intensity at the current moment.

[0349] Step SB: When the light-chasing conditions are met, the following light-chasing operation is initiated to automatically adjust the drying position of the clothes so that the clothes are always in a drying position with appropriate light intensity:

[0350] Step SB10: Determine a designated drying location that matches the current drying condition information based on the current drying condition information, wherein the designated drying location is determined locally and / or in the cloud based on stored historical drying condition information and corresponding historical drying locations;

[0351] In this embodiment, the designated drying location can be determined by matching the historical drying condition information of the clothes drying machine with the corresponding historical drying location, or by matching the historical drying condition information and corresponding historical drying location of another clothes drying machine that has a high degree of matching installation conditions. A high degree of matching installation conditions specifically refers to the same installation location and / or the same installation orientation.

[0352] The historical drying condition information is information about the clothes drying machine's drying conditions over a predetermined period of time in the past. This drying condition information also includes at least one of the following: installation location, installation orientation, drying date, current time, daytime period, weather information, and light intensity. The predetermined period of time may be one year, six months, one month, or the like, and is not limited in this embodiment of the present application.

[0353] The clothes dryer can locally store its historical drying condition information and corresponding historical drying positions. It can also store historical drying condition information and corresponding historical drying positions of other clothes dryers that have a high degree of matching with the clothes dryer's installation conditions, as sent from the cloud. When the clothes dryer performs a light tracking operation, it determines the historical drying condition information that matches its current drying condition information from the locally stored information and determines the historical drying position corresponding to the matching historical drying condition information as the designated drying position that matches the current drying condition information.

[0354] The cloud can store historical drying condition information and corresponding historical drying positions for multiple clothes drying machines. When a clothes drying machine performs a light tracking operation, it sends its current drying condition information to the cloud. The cloud then identifies historical drying condition information that matches its current drying condition information from the massive amount of information, and determines the historical drying position corresponding to this matching historical drying condition information as the designated drying position that matches the current drying condition information. This designated drying position is then fed back to the clothes drying machine, allowing it to receive and determine the designated drying position.

[0355] A mapping relationship is established between the time points in the historical drying condition information and the historical drying positions, and the historical drying positions are associated with the time points in the historical drying condition information and stored.

[0356] Step SB20: Control the clothes on the clothes drying machine to be in the designated drying position.

[0357] For this embodiment, controlling the clothes on the clothes drying machine to be in the designated drying position includes: controlling the clothes drying rod of the clothes drying machine to be at a height corresponding to the designated drying position, and / or controlling the clothes on the clothes drying rod of the clothes drying machine to move along the clothes drying rod to the designated drying position.

[0358] The clothes drying machine comprises a main unit and a clothes drying rod. A longitudinal power device is installed on the main unit. The main unit and the clothes drying rod are connected via a lifting mechanism. The lifting mechanism is controlled by the longitudinal power device to drive the clothes drying rod to move up and down.

[0359] Specifically, the longitudinal power unit on the main unit includes a motor driver and a DC motor. The motor driver is connected to the DC motor, which is then connected to the lifting mechanism of the clothes drying machine. The lifting mechanism is then connected to the clothes drying rod. This allows the DC motor connected to the motor driver to drive the clothes drying rod to move upward and downward. When the clothes drying machine determines a designated drying position, the longitudinal power unit controls the clothes drying rod to a height corresponding to the designated drying position, thereby ensuring that the clothes on the clothes drying rod are in the designated drying position.

[0360] Furthermore, the clothes on the clothes drying rack can be moved along the clothes drying rod, meaning that the clothes drying position can be adjusted laterally. The clothes drying rod comprises a clothes drying rod body, a chain for driving the clothes on the clothes drying rod to move along the clothes drying rod, and a hanger for hanging the clothes. A chain movement groove is defined below or on the outer side of the clothes drying rod body. The chain movement groove is configured to accommodate the chain, and a plurality of hangers are connected to the chain at intervals, which can be used to hang or clamp the clothes. A transverse power device is disposed on the clothes drying rod and connected to the chain received in the chain movement groove of the clothes drying rod. The transverse power device drives the chain to move within the chain movement groove to drive the clothes on the hanger to move along the clothes drying rod.

[0361] Specifically, the transverse power device on the clothes drying rod includes a motor driver and a stepper motor. The first motor driver is connected to the stepper motor, thereby enabling the stepper motor connected to the first motor driver to drive the clothes on the clothes drying rod to move along the clothes drying rod. When the clothes drying machine determines a designated drying position, the transverse power device controls the movement of the clothes on the clothes drying rod, thereby placing the clothes on the clothes drying rod in the designated drying position.

[0362] In one possible implementation, the clothes drying rod is a circular rod, and the clothes on the clothes drying machine can be moved along the circular route of the clothes drying rod. Specifically, when the clothes drying machine determines a designated drying position, the clothes on the circular rod are controlled to move by a transverse power device, so that the clothes on the circular rod are in the designated drying position.

[0363] It can be understood that the longitudinal power device and the transverse power device can work simultaneously or successively to control the lifting and lowering of the clothes drying rod of the clothes drying machine and the movement of the clothes on the clothes drying rod along the clothes drying rod. After the longitudinal and transverse movements, the clothes are in the designated drying position.

[0364] The present application provides a light-chasing drying control method, which starts the light-chasing operation only when the current drying condition information of the clothes drying machine meets the light-chasing conditions, which can avoid power consumption waste caused by ineffective light-chasing, and the designated drying position of the clothes drying machine controlled in the light-chasing operation is obtained by matching historical data. After the designated drying position is determined, the drying position of the clothes can be automatically adjusted so that the clothes are always in a drying position with appropriate light intensity. There is no need to collect time-consuming and energy-consuming light intensity and calculate it before determining the designated drying position before each light-chasing drying, which can significantly improve the efficiency and intelligence of light-chasing drying.

[0365] In some embodiments, obtaining the current drying condition information of the clothes drying machine when the light tracking function is turned on in step SA includes: obtaining the longitude and latitude information of the clothes drying machine when the light tracking function is turned on; and determining the current drying condition information of the clothes drying machine through networking or local detection based on the longitude and latitude information.

[0366] For this embodiment, the duration and direction of sunshine are both affected by the longitude and latitude of the installation point of the clothes drying machine. Therefore, when obtaining the current drying condition information, the positioning information of the installation point of the clothes drying machine when the tracking function is turned on is first obtained based on the positioning function of the clothes drying machine, that is, the longitude and latitude information, and then the current drying condition information of the clothes drying machine is determined based on the longitude and latitude information of the clothes drying machine.

[0367] The installation location and installation orientation in the current drying condition information can be determined through local detection, the daytime time period can be determined through networking, and the drying date, current time, weather information, and light intensity can be determined through networking or local detection. Specifically, the corresponding current drying condition information can be determined locally through functional modules or sensors of the clothes drying machine, and received from the cloud through networking.

[0368] In some embodiments, the current drying condition information of the clothes drying machine may satisfy one or more light tracking conditions.

[0369] If the current drying condition information includes the installation location, the current time, and the daytime period, then the light tracking condition can be satisfied if the current time is within the daytime period. For example, if the daytime period at the clothes drying machine installation location is from 7:00 AM to 6:00 PM and the current time is 12:00 PM, then the light tracking condition is satisfied if the current time is within the daytime period.

[0370] If the current drying condition information includes the installation location and weather information, and the weather information includes a probability of rain, then the tracking condition can be met if the probability of rain in the weather information is less than a predetermined probability value. The predetermined probability value can be 85%, 75%, 60%, etc., and is not limited to this embodiment of the present application.

[0371] If the current drying condition information includes the installation location and light intensity, then the light chasing condition can be satisfied when the light intensity is greater than a predetermined intensity value, which can be 1000 lux, but is not limited to this in the present embodiment.

[0372] In some embodiments, the designated drying location in step SB10 is determined by any of the following methods:

[0373] Method 1: Match and determine the historical drying condition information on the same day as the drying date, and determine the historical drying position corresponding to the historical drying condition information and the current time point as the designated drying position.

[0374] In this method, if the installation point of the clothes drying machine remains unchanged and the light chasing conditions are met, the drying condition information of the same day in different years should be similar, then the historical drying position corresponding to the historical drying condition information can be used as the designated drying position for the current drying date. Specifically, the designated drying position corresponds one-to-one to the historical drying position at the same time point. Among them, the same day can refer to the same day of the Gregorian calendar date or the same day of the lunar calendar date. Therefore, when the light chasing operation is turned on, the drying date and current time point are extracted from the current drying condition information, and the historical drying condition information is filtered by date, and the historical drying condition information of the same day as the drying date is matched and determined, and finally the historical drying position corresponding to the historical drying condition information and the current time point is determined as the designated drying position.

[0375] This method can be used to determine the designated drying position from historical information. Compared with the time-consuming and energy-consuming collection of light intensity and calculation to determine the designated drying position, this method can quickly match and determine the designated drying position from massive data, significantly reducing the amount of calculation required for the clothes drying machine's light tracking operation, and significantly improving the efficiency and intelligence of light tracking drying.

[0376] Method 2: Match and determine historical drying condition information that is the same as the weather information or light intensity at the current time point, and determine the historical drying position corresponding to the historical drying condition and the current time point as the designated drying position.

[0377] In this method, when the installation point of the clothes drying machine remains unchanged and the light chasing conditions are met, for the drying condition information of different dates, if the weather information or light intensity of the two at the same time point is the same, then the drying condition information of the two at other same time points in the day should be close, and the historical drying position corresponding to the historical drying condition information can be used as the designated drying position under the current weather information or light intensity. Specifically, the designated drying position corresponds one-to-one to the historical drying position at the same time point. Therefore, when the light chasing operation is turned on, the current time point and weather information or light intensity are extracted from the current drying condition information, and the weather information or light intensity corresponding to the current time point in the historical drying condition information is matched, and the historical drying condition information that is the same as the weather information or light intensity at the current time point is matched and determined, and finally the historical drying position corresponding to the historical drying condition and the current time point is determined as the designated drying position.

[0378] This method can be used to determine the designated drying position from historical information. Compared with the time-consuming and energy-consuming collection of light intensity and calculation to determine the designated drying position, this method can quickly match and determine the designated drying position from massive data. Its data accuracy is equivalent to the position result obtained by real-time light tracking operation and calculation, but it can significantly reduce the amount of calculation required for the light tracking operation of the clothes drying machine, significantly improving the efficiency and intelligence of light tracking drying.

[0379] In some embodiments, as shown in FIG11 , after step SB20 controls the clothes on the clothes drying machine to be in the designated drying position, the step further includes:

[0380] Step SB30: obtaining an updated current time point according to a predetermined period, obtaining an updated designated drying position according to the updated current time point, and controlling the clothes on the clothes drying machine to be at the updated designated drying position.

[0381] For this embodiment, the designated drying positions are different at different time points in a day. It is necessary to obtain the updated designated drying positions regularly and control the clothes on the clothes drying machine to be in the updated designated drying positions to achieve continuous light-chasing drying, so that the clothes are always in the drying position with appropriate light intensity throughout the day.

[0382] As previously described, for the matched historical drying condition information, the designated drying position corresponds one-to-one to the historical drying position at the same time point. Since step SB10 has already determined the historical drying condition information that matches the current drying condition information, specifically the historical drying condition information for the same day as the drying date, or the historical drying condition information with the same weather information or light intensity as the current time point, when determining the updated designated drying position in this step, there is no need to re-match. The historical drying condition information matched in the previous step and the updated historical drying position at the current time point can be directly determined as the updated designated drying position. This further reduces the amount of computation and time required for the clothes drying machine's light tracking operation, further improving the efficiency and intelligence of light tracking drying.

[0383] Among them, in order to distinguish it from the predetermined period in other steps, this predetermined period is the first predetermined period. The first predetermined period is the time interval for updating the clothes drying position, which can be a time period of one hour, half an hour, etc., which can be determined according to actual application requirements. The embodiment of the present application does not limit this.

[0384] Among them, the updated designated drying location is the historical drying condition information corresponding to the matching determined in the local and / or cloud and the historical drying location of the updated current time point, that is, as mentioned above, the historical drying condition information and the corresponding historical drying location can be stored locally and / or in the cloud, and the specific matching process is the same as the aforementioned feature, which will not be repeated here.

[0385] In other embodiments, before obtaining the updated designated drying position according to the updated current time point, it is also possible to first determine whether the clothes drying machine still meets the light chasing conditions, and only when the light chasing conditions are met will the step of obtaining the updated designated drying position be continued to further avoid power consumption waste caused by invalid light chasing.

[0386] In some embodiments, the light-chasing drying control method further includes: during the start-up of the light-chasing operation, monitoring the current drying condition information of the clothes drying machine according to a predetermined cycle, and controlling the clothes on the clothes drying machine to be in the drying completion position when the light-chasing drying completion conditions are met.

[0387] In this embodiment, during the light-chasing operation, if the clothes drying machine's current drying condition information meets the light-chasing drying completion conditions, the light-chasing operation can be terminated, and the clothes on the clothes drying machine can be controlled to the drying completion position. Generally, the drying completion position is when the clothes drying rod is raised to the top, i.e., the highest position of the clothes drying machine's lifting range, to prevent the clothes from blocking the room's light or being exposed to secondary environmental contamination when in the low position. In addition, after the clothes on the clothes drying machine are controlled to the drying completion position, a clothes collection reminder can be sent to the mobile terminal associated with the clothes drying machine.

[0388] Among them, in order to distinguish it from the predetermined period in other steps, this predetermined period is the second predetermined period. The second predetermined period is the time interval for confirming whether the chasing light drying is completed. It can be a time period of one hour, half an hour, etc., which can be determined according to actual application requirements. The embodiment of this application does not limit this.

[0389] In this embodiment, the current drying condition information of the clothes drying machine may satisfy one or more conditions for completing the light-chasing drying process.

[0390] Condition 1: The real-time weight of the clothes on the clothes drying machine is less than or equal to a predetermined proportion of the initial weight of the clothes; the initial weight of the clothes is detected before the light chasing operation is started, and the real-time weight of the clothes is monitored during the light chasing operation.

[0391] Regarding this condition, before starting the light-chasing operation, generally, a weight sensor is used to detect the initial weight of the clothes on the clothes drying machine when the clothes are detected. During the light-chasing operation, the real-time weight of the clothes on the clothes drying machine is continuously monitored. When the real-time weight is less than or equal to a predetermined ratio of the initial weight, it indicates that the moisture content of the clothes has been reduced to a level that can be considered dry, and the light-chasing drying condition is met. The predetermined ratio can be 85%, 75%, 60%, etc., and is not limited to this in the present embodiment.

[0392] Condition 2: The current time point is outside the daytime period.

[0393] If the current drying condition information includes the installation location, the current time, and the daytime period, then the condition for completing the sun-following drying process may specifically be that the current time is outside the daytime period. For example, if the daytime period at the clothes drying machine installation location is 7:00 AM to 6:00 PM and the current time is 7:00 PM, then the condition for completing the sun-following drying process is that the current time is outside the daytime period.

[0394] Condition three: the rainfall probability in the weather information reaches a predetermined probability value.

[0395] If the current drying condition information includes the installation location and weather information, and the weather information includes a probability of rainfall, then the condition for completing the sun-following drying process may specifically be that the probability of rainfall in the weather information reaches a predetermined probability value. The predetermined probability value may be 5%, 15%, 20%, etc., and is not limited to this in the present embodiment.

[0396] In some embodiments, the clothes drying machine includes a light intensity detector that can be moved along the clothes drying rod. The historical drying position is the drying position with the best light intensity, which is obtained in advance through a light tracking and collection operation.

[0397] The clothes drying machine has a light tracking and data collection function. To later match the designated drying position based on historical data, it is necessary to perform light tracking and data collection when the clothes drying machine is used in the early stage and record the corresponding drying data as historical drying condition information and corresponding historical drying positions.

[0398] In this embodiment, the clothes drying machine includes a main unit and a clothes drying rod. The clothes on the clothes drying machine can be moved along the clothes drying rod. Its specific structure is as described above and will not be repeated here. On this basis, the clothes drying machine also includes a light intensity detector that can be moved along the clothes drying rod. The light intensity detector includes a housing, a light intensity detection chip housed in the housing, a drive motor and a roller. A roller motion groove that can accommodate the roller is provided above the clothes drying rod. The gear edge of the drive motor is engaged with the gear edge of the roller. When the motor is running, it can drive the roller to rotate synchronously, thereby moving along the clothes drying rod in the roller motion groove, realizing the movement of the light intensity detector along the clothes drying rod. In the early stage of using the clothes drying machine for light tracking and collection operations, by controlling the light intensity detector to move along the clothes drying rod and detecting the light intensity, the light intensity corresponding to the corresponding drying position on the clothes drying rod can be collected.

[0399] As shown in FIG12 , the historical drying positions are obtained in advance through the following light tracking and collection operations:

[0400] Step SC10: controlling the clothes drying rod of the clothes drying machine to be at several designated heights in succession according to a predetermined cycle, and controlling the light intensity detector to move along the clothes drying rod and detect multiple light intensities when the clothes drying rod is at the designated heights.

[0401] In one possible implementation, the designated heights are the heights corresponding to when the clothes-drying rod stops at certain time intervals or distances during its ascent or descent. For example, the designated heights are the heights corresponding to when the clothes-drying rod stops every 5 milliseconds when descending from its highest position to its lowest position. Another example is the heights corresponding to when the clothes-drying rod stops every 10 centimeters when descending from its highest position to its lowest position. When the clothes-drying rod is at the designated heights, the light detector is controlled to move along the rod and detect multiple light intensities, thereby collecting the light intensities corresponding to the corresponding drying positions on the rod when the rod is at the designated heights.

[0402] In a preferred implementation, the designated heights are specifically the highest and lowest positions in the clothes drying machine's lifting stroke. The clothes drying rod of the clothes drying machine is controlled to be positioned successively at the highest and lowest positions in the lifting stroke. When the rod is at the highest or lowest position, a light detector is controlled to move along the rod and detect multiple light intensities, thereby collecting the light intensities corresponding to the corresponding drying positions on the rod when the rod is at the highest or lowest position. In this method, by collecting the light intensities at the highest and lowest positions of the rod to analyze and determine the optimal drying position, the time spent on tracking light acquisition operations and the amount of computation can be reduced, thereby improving the efficiency of early tracking light drying.

[0403] Among them, in order to distinguish it from the predetermined period in other steps, this predetermined period is the third predetermined period. The third predetermined period is the time interval for controlling the light intensity collection, which can be a time period of one hour, half an hour, etc., which can be determined according to actual application requirements. The embodiment of this application does not limit this.

[0404] Step SC20: Send the detected light intensity to the cloud, so that the cloud can analyze and obtain the optimal light intensity drying position corresponding to different time points. The optimal light intensity drying position is stored locally and / or in the cloud.

[0405] For this embodiment, the clothes drying machine sends the detected light intensity to the cloud. After receiving the large amount of light intensities collected by the clothes drying machine, the cloud performs big data analysis to obtain the maximum light intensity of the clothes drying machine at different time points, and determines the drying position corresponding to the maximum light intensity, that is, the corresponding specified height and / or drying position on the drying rod as the drying position with the best light intensity. The drying position with the best light intensity, the time point and the clothes drying machine identification code are associated and stored in the cloud, and / or the drying position with the best light intensity is sent to the clothes drying machine for storage.

[0406] Furthermore, in some embodiments, the light tracking and collection operation also includes: obtaining the drying condition information of the clothes drying machine according to a predetermined period; and associating and storing the drying condition information with the optimal drying position of the light intensity obtained by the corresponding analysis locally or in the cloud as historical drying condition information and the corresponding historical drying position.

[0407] In this embodiment, this predetermined period corresponds to the third predetermined period, which is the time interval for controlling light intensity collection. That is, during each period of light intensity collection, the clothes drying condition information of the clothes drying machine must be simultaneously acquired so that the analyzed optimal light intensity drying position can be associated with the drying condition information at the same time and stored as historical drying condition information and the corresponding historical drying position.

[0408] If the optimal drying position for light intensity is stored in the cloud, the clothes drying machine will send the acquired drying condition information to the cloud. After receiving the drying condition information, the cloud will associate and store the drying condition information corresponding to the time point, the optimal drying position for light intensity, and the clothes drying machine identification code in the cloud as historical drying condition information and the corresponding historical drying position for subsequent light tracking operations.

[0409] If the optimal drying position with the best light intensity is stored locally, the clothes drying machine will associate the drying condition information corresponding to the time point with the received optimal drying position and store it locally as historical drying condition information and the corresponding historical drying position for subsequent light chasing operations.

[0410] In some embodiments, before starting the light-tracking acquisition operation, the method further includes: obtaining current drying condition information of the clothes drying machine when the light-tracking acquisition function is turned on, and determining whether the light-tracking acquisition condition is met based on the current drying condition information.

[0411] For this embodiment, the clothes drying machine has a light tracking and collection function. When the light tracking and collection function of the clothes drying machine is turned on and the current drying condition information meets the light tracking and collection conditions, the clothes drying machine can collect light intensity at different heights of the clothes drying rod and / or at different drying positions on the clothes drying rod. After big data analysis, the drying position with the best light intensity is obtained, and it will be used as historical data for subsequent light tracking operations.

[0412] The light-chasing acquisition conditions can be pre-set by the clothes dryer's factory defaults and / or user-defined. These conditions limit the current drying conditions for which the clothes dryer can effectively chase light. If the current drying conditions do not meet the light-chasing acquisition conditions, even if light-chasing acquisition is performed, it will be ineffective, and the collected data cannot be used to analyze and accurately determine the optimal drying position for light intensity. By only initiating the light-chasing operation when the clothes dryer's current drying conditions meet the light-chasing acquisition conditions, power consumption caused by ineffective light-chasing detection can be avoided, improving the efficiency and intelligence of light-chasing drying.

[0413] In some embodiments, obtaining the current drying condition information of the clothes drying machine when the light tracking and collecting function is turned on includes: obtaining the longitude and latitude information of the clothes drying machine when the light tracking function or the light tracking and collecting function is turned on; and determining the current drying condition information of the clothes drying machine through networking or local detection based on the longitude and latitude information.

[0414] For this embodiment, the duration and direction of sunshine are affected by the longitude and latitude of the installation point of the clothes drying machine. Therefore, when obtaining the current drying condition information, the positioning information of the installation point of the clothes drying machine when the tracking light function is turned on is first obtained based on the positioning function of the clothes drying machine, that is, the longitude and latitude information, and then the current drying condition information of the clothes drying machine is determined based on the longitude and latitude information of the clothes drying machine.

[0415] The installation location and installation orientation in the current drying condition information can be determined through local detection, the daytime time period can be determined through networking, and the drying date, current time, weather information, and light intensity can be determined through networking or local detection. Specifically, the corresponding current drying condition information can be determined locally through functional modules or sensors of the clothes drying machine, and received from the cloud through networking.

[0416] In some embodiments, the current drying condition information of the clothes drying machine may satisfy one or more tracking light collection conditions.

[0417] If the current drying condition information includes the installation location, the current time, and the daytime period, then the tracking light acquisition condition can specifically be satisfied if the current time is within the daytime period. For example, if the daytime period at the clothes drying machine installation location is 7:00 AM to 6:00 PM and the current time is 12:00 PM, then the tracking light acquisition condition is satisfied if the current time is within the daytime period.

[0418] If the current drying condition information includes the installation location and weather information, and the weather information includes a probability of rainfall, then the tracking light acquisition condition can be specifically satisfied if the probability of rainfall in the weather information is less than a predetermined probability value. The predetermined probability value can be 85%, 75%, 60%, etc., and is not limited to this embodiment of the present application.

[0419] If the current drying condition information includes the installation location and light intensity, then the tracking light collection condition may specifically be that the light intensity is greater than a predetermined intensity value, which may specifically be 1000 lux, but is not limited to this in the present embodiment.

[0420] It is understandable that the light tracking collection conditions and the light tracking conditions that the current drying condition information of the clothes drying machine must satisfy may be the same.

[0421] In addition, based on the same principles as the above-mentioned light-chasing drying control method embodiment, the embodiment of the present application also provides a light-chasing drying control system, which includes: a controller and a drying condition acquisition device connected to the controller; wherein:

[0431] For this embodiment, the light intensity detector is connected to the controller, and the light intensity detector is movably set on the drying rod of the drying equipment through the first power device. The controller can control the light intensity detector to move along the drying rod, that is, to move in the horizontal direction, through the first power device, and collect light intensity information at different positions in the horizontal direction of the drying rod during the movement.

[0432] In addition, the drying rod can also move up and down relative to the main unit of the drying equipment, and the light intensity detector can also move up and down with the drying rod, that is, move in the vertical direction, and collect light intensity information during the lifting process.

[0433] In this embodiment, the light intensity detector can collect light intensity information during movement at a predetermined frequency or a predetermined moving distance. For example, light intensity information is collected every 2 ms during movement. For another example, light intensity information is collected every 10 cm during movement. The controller controls the lifting and lowering of the clothes-drying rod and the movement of the light intensity detector along the clothes-drying rod, and performs grid scanning to detect light intensity information based on the predetermined frequency or predetermined moving distance, thereby detecting light intensity information at different positions. The light intensity detector transmits the collected light intensity information to the controller, so that the controller determines the degree of drying of the clothes at different positions based on the collected light intensity information.

[0434] As a preferred implementation, the predetermined frequency is related to the total duration required for the light intensity detector to be raised and lowered and moved horizontally, and the predetermined frequency is calculated by dividing the total duration in equal proportion. The predetermined movement distance is related to the total movement distance of the light intensity detector to be raised and lowered and moved horizontally, and the predetermined movement distance is calculated by dividing the total movement distance in equal proportion.

[0435] It should be noted that the predetermined frequency and the predetermined moving distance can be determined according to actual needs, and the embodiments of the present application do not limit this.

[0436] The first power unit includes a first motor driver and a stepper motor. The controller is connected to the stepper motor via the first motor driver, and the stepper motor is connected to a light intensity detector. Under the control of the controller, the stepper motor connected via the first motor driver drives the light intensity detector to move along the clothes-drying rod. Specifically, the controller sends a specified number of pulses to the first power unit to control the stepper motor to rotate a specified angle, thereby causing the light intensity detector to move along the clothes-drying rod to a target position.

[0437] In the clothes drying control system provided in this embodiment, the controller controls the light intensity detector to move along the clothes drying rod through the first power device and collects light intensity information during the movement. The light intensity detector can also move up and down with the clothes drying rod and collect light intensity information during the lifting process. The controller can determine the degree of drying of clothes at different positions based on the light intensity information collected at different positions in the horizontal and vertical directions, so as to effectively help to intelligently and accurately identify sunlight for clothes drying.

[0438] In some embodiments, as shown in FIG14 , the clothes drying control system further includes a clothes detector and a second power device connected to the controller.

[0439] In this embodiment, the clothing detector is connected to the controller and is used to detect clothing status information of the clothes on the clothes drying rod and send the detected clothing status information to the controller. The clothing status information includes but is not limited to information such as temperature, humidity, and weight of the clothes.

[0440] The second power unit is disposed on the drying rod and is used to drive the laundry on the drying rod to move along the drying rod. The second power unit includes a first motor driver and a stepper motor. The controller is connected to the stepper motor via the first motor driver. Under the control of the controller, the stepper motor connected via the first motor driver drives the laundry on the drying rod to move along the drying rod. Specifically, the controller sends a specified number of pulses to the second power unit to control the stepper motor to rotate a specified angle, thereby moving the laundry on the drying rod to a target position along the drying rod.

[0441] In this embodiment, the controller determines the degree of drying of the clothes at different locations based on the collected light intensity information, and analyzes and determines the optimal drying position for the clothes in combination with the clothing status information. The optimal drying position is the position with the highest light intensity within the range of the rod's elevation and movement of the clothes along the rod. After determining the optimal drying position based on the clothing status information and the light intensity information, the controller controls the operation of the second power unit to move the clothes on the rod along the rod to the optimal drying position. Specifically, the controller can also control the movement of specific clothes on the rod, such as clothes with the highest humidity, to the optimal drying position along the rod.

[0442] In some embodiments, the clothes-drying rod is an annular clothes-drying rod, which includes a clothes-drying rod body, a chain for driving the clothes on the clothes-drying rod to move along the clothes-drying rod, and a hanging part for hanging the clothes.

[0443] In this embodiment, the clothes drying rod is a circular clothes drying rod, and clothes can be moved along the circular path of the clothes drying rod. Specifically, a chain movement groove is formed on the bottom or outer side of the clothes drying rod body, and the chain is connected to a plurality of spaced hanging parts, which can be used to hang or clamp clothes.

[0444] The second power device is arranged on the drying rod, specifically a chain connected to and accommodated in the chain motion groove of the drying rod. The second power device is used to drive the chain to move in the chain motion groove to drive the clothes on the hanging part to move along the drying rod.

[0445] In some embodiments, the clothing detector includes a weight detector, a humidity detector, and a temperature detector connected to a controller.

[0446] The weight detector is arranged on the clothes drying rod, specifically, on the clothes drying rod body, and is used to detect the clothes weight information and send the detected clothes weight information to the controller.

[0447] The humidity detector is arranged on the clothes drying rod, specifically, on the clothes drying rod body, and is used for detecting clothes humidity information of the clothes on the clothes drying rod when the clothes on the clothes drying rod move along the clothes drying rod and sending the detected clothes humidity information to the controller.

[0448] The temperature detector is arranged on the clothes-drying rod, specifically, on the clothes-drying rod body, and is used to detect ambient temperature information and send the detected ambient temperature information to the controller.

[0449] After determining the optimal drying position based on the laundry humidity information, the ambient temperature information, and the light intensity information, the controller controls the second power device to operate, thereby controlling the laundry on the drying rod to move along the drying rod to the optimal drying position. Specifically, the controller can control the movement of specific laundry on the drying rod, such as the laundry with the highest humidity, to the optimal drying position along the drying rod.

[0450] Furthermore, in some embodiments, the controller is also connected to a third power device.

[0451] The drying device includes a third power unit mounted on a main unit of the drying device. A controller controls the raising and lowering of the drying rod via the third power unit. The controller is configured to control the operation of the third power unit based on laundry weight information transmitted by a weight detector or laundry humidity information transmitted by a humidity detector, thereby raising the drying rod to a drying completion position. Typically, the drying completion position is when the drying rod is raised to the top, i.e., the highest position within the drying device's lifting range.

[0452] The third power device includes a second motor driver and a DC motor. The controller is connected to the DC motor through the second motor driver. The DC motor is connected to the lifting mechanism of the drying equipment. The lifting mechanism is connected to the drying rod. Under the control of the controller, the DC motor connected through the second motor driver drives the drying rod to perform lifting movements.

[0453] In some embodiments, the clothes drying control system also includes a solar power supply device connected to the controller, and the solar power supply device includes a solar panel and a lithium battery. The solar power supply device is used to charge the lithium battery through the solar panel to supply power to the drying equipment, thereby achieving energy saving and strong adaptability in drying.

[0454] In some embodiments, the clothes drying control system further includes a WIFI module connected to the controller, and the WIFI module is used to communicate with the cloud to obtain information such as weather forecast from the cloud.

[0455] The following is a detailed description of the drying and tracking light control system provided in the embodiment of the present application.

[0456] At present, some of the light-tracking technologies for clothes drying machines are completely dependent on the light-tracking model set in the background. Specifically, the background light-tracking model analyzes and calculates the parameters input in advance by the user and some parameters obtained through the network to obtain the lighting conditions, and then controls the lifting and lowering of the clothes drying machine. Some use light sensors set at fixed positions such as wall-mounted remote controls to detect the lighting conditions to control the lifting and lowering of the clothes drying machine. It is impossible to achieve real-time and continuous light tracking when the light direction shifts.

[0457] Based on the problems existing in the prior art, this embodiment provides a drying light tracking control system, which is applied to a clothes drying machine. As shown in Figure 6, the control system includes a controller and a light tracking device. The light tracking device includes multiple light sensors, and each light sensor is connected to the controller respectively.

[0458] In this embodiment, light sensors are installed on the clothes drying rod of the clothes drying machine to monitor the light intensity on the rod in real time and transmit this information to a controller. At least two light sensors are arranged along the direction of movement of the rod. As shown in Figure 4a, light sensors A and B are arranged along the direction of movement of the rod. In this embodiment, the light sensors can be BH1750FVI ambient light sensor ICs, which can measure ambient light intensity (lux).

[0459] In an embodiment, one or more groups of light sensors may be included. As shown in FIG4b, when there are multiple groups, each group of light sensors is arranged along the horizontal position of the clothes-drying rod, wherein one or more groups of light sensors meet the following conditions: at least two light sensors are arranged along the direction of movement of the clothes-drying rod. In addition, as shown in FIG4c, more than three light sensors may be provided in each group of light sensors. Among them, the light sensors arranged along the direction of movement of the clothes-drying rod in the same group may be sensors arranged on the same vertical line on the ground, that is, in a vertical arrangement relationship, as shown in FIG4a to 4c; or they may be sensors arranged within a certain range of horizontal distance and along the direction of movement of the clothes-drying rod, that is, in the up and down direction, as shown in FIG4d. Specifically, they may be arranged according to the lighting conditions of the installation location of the clothes-drying machine.

[0460] In this embodiment, as shown in Figure 7, the light-chasing device further includes a mounting body 1. A light sensor in the light-chasing device is mounted on the mounting body, which is then mounted on the clothes-drying pole. The mounting body can be attached to the clothes-drying pole by magnetic attraction. A protruding Fresnel hemispherical lens 2 is embedded in the mounting body. Each light sensor in the light-chasing device is mounted under each protruding Fresnel hemispherical lens.

[0461] In this embodiment, to determine the direction of light deviation, at least two light sensors can be installed on the same mounting body. As shown in Figure 7, after the mounting body is attached to the clothes-drying rod, the at least two light sensors on the mounting body are arranged along the direction of the rod's movement. Alternatively, only one light sensor can be installed on the mounting body, in which case at least two mounting bodies are required, arranged along the direction of the rod's movement. If multiple sets of light sensors are provided, each set of light sensors can be installed on a corresponding mounting body, with each mounting body arranged transversely along the clothes-drying rod.

[0462] In this embodiment, the controller is directly or indirectly connected to the motion drive mechanism of the clothes-drying rod. The controller can determine the change in light intensity of the clothes-drying rod based on the light intensity monitored by the light sensor, and further determine the direction of light offset, so as to control the movement of the clothes-drying rod based on the light offset direction, and determine the drying position of the clothes-drying rod based on the light intensity information during the movement of the clothes-drying rod.

[0463] In this embodiment, the controller can be a clothes drying machine main controller or an independently set controller. When it is a clothes drying machine main controller, the light sensor set on the clothes drying rod is connected to the clothes drying machine main controller by wire, and the clothes drying machine main controller implements the light tracking control method provided in the above embodiment. The clothes drying machine main controller can be an MCU. The controller is directly or indirectly connected to the motion mechanism of the clothes drying rod, which means that when the controller is a clothes drying machine main controller, the controller is directly connected to the motion drive mechanism of the clothes drying rod and directly sends corresponding control instructions to the motion drive mechanism of the clothes drying rod to control the movement of the clothes drying rod. When the controller is an independently set controller, the controller is indirectly connected to the motion drive mechanism of the clothes drying rod, that is, there is no direct connection between the controller and the motion drive mechanism of the clothes drying rod, and the control needs to be achieved through the clothes drying rod main controller.

[0464] In this embodiment, if it is independent of other controllers of the clothes drying machine main controller, the controller can communicate with the clothes drying machine main controller through a wireless communication module or a wired connection. The controller sends the clothes drying rod lifting control instruction to the clothes drying machine main controller, and controls the working state of the clothes drying machine motor through the clothes drying machine main controller to realize the clothes drying rod lifting control during the light chasing process; in addition, the controller can also be set to only receive the light intensity information sent by the light sensor and send the received light intensity information to the clothes drying machine main controller. The clothes drying machine main controller determines the light offset direction based on the light intensity information and controls the clothes drying rod to be lifted and lowered to the optimal drying position according to the light offset direction. The wireless communication module connected to the above controller can be a Bluetooth module, a WiFi module, a ZigBee module, a radio frequency module, etc. The above controller can also use an MCU.

[0465] As shown in FIG6 , when the controller of this embodiment is an independently set controller, the controller can be set on the clothes-drying rod and connected to the light sensor also set on the clothes-drying rod. When the light-chasing device of this embodiment includes an installation body, the controller can also be set on the installation body.

[0466] In the system of this embodiment, the light-chasing controller may further include a solar panel mounted on the clothes drying rod. When the controller is independently configured, the controller is connected to the solar panel, and power is supplied to the controller and the light sensor via the solar panel. For an independently configured controller, when the controller is normally powered, it is typically connected to the clothes drying machine controller via a wired connection, and powered by the clothes drying machine input power. In this case, bidirectional communication between the controller and the clothes drying machine controller can be configured. When the controller is powered by a solar panel, the collected light data is transmitted unidirectionally only when sunlight shines on the solar panel mounted on the controller and can normally drive the controller. In this case, the controller and the clothes drying machine controller communicate unidirectionally, i.e., the controller does not receive data transmitted by the clothes drying machine controller, but the transmitted data can be received by the clothes drying machine controller and then executed accordingly. This reduces the cost of the controller and eliminates the need for additional wired power supply. No power is required from the clothes drying machine controller for wired power supply, making the structure simpler and directly applicable to current clothes drying machines without requiring significant structural improvements to the current clothes drying machine.

[0467] In this embodiment, multiple light sensors arranged along the movement direction of the clothes-drying rod obtain light intensity information in real time and transmit it to the controller; as shown in Figure 4a, light sensor A and light sensor B are arranged along the movement direction of the clothes-drying rod, and light sensor B is above light sensor C.

[0468] In this embodiment, the controller judges the received light intensity information to determine whether it is less than a set value, such as 10,000 lux. If so, it means that the light intensity at the current position of the clothes-drying pole is weak, and the controller can turn on the chasing light. In this embodiment, the controller can compare the light intensity information detected by one or more light sensors with the set value. When there are multiple light sensors, the average light intensity detected by each light sensor can be taken, and the average light intensity can be compared with the set value to determine whether to turn on the chasing light.

[0469] Among them, after turning on the light tracking, the controller obtains the light intensity detected by each light sensor at each moment in the specified time interval to obtain the light intensity information of each position corresponding to each light sensor at each moment in the specified time interval, that is, the light change of the clothes drying pole. By calculating the sum of the light intensity differences of two positions with an upper and lower relationship at the above-mentioned moments, the total light intensity difference SUM can be determined, and the total light intensity difference SUM is compared with the light threshold to determine the direction of light offset. The light threshold can be set to 3000~6000lux; specifically: if SUM>light threshold, it is determined that the light is offset upward; if SUM<-light threshold, it is determined that the light is offset downward. The principle of determining the light offset in this embodiment is that within the specified time, if the sum of the light intensity of the upper position is greater than that of the lower position and is greater than the set threshold, it means that the light is moving upward. Conversely, if the sum of the light intensity of the upper position is smaller than that of the lower position and is less than the set threshold, the light is moving downward. The above-mentioned specified time refers to the time from the last time the clothes drying rod stopped to the current time, that is, the time when the light intensity is less than the set value.

[0470] For example, if this embodiment only includes two light sensors as shown in FIG4a, and the two light sensors A and B are located at positions a and b of the clothes-drying rod, respectively, with position b being above position a, then the light intensity information of positions a and b at each moment within a specified time interval is obtained, and then the sum of the light intensity differences between positions a and b at each moment is calculated, that is, Where Lb(k) is the light intensity at position b at time k, detected by light sensor b at position b. La(k) is the light intensity at position a at time k, detected by light sensor a at position a. n is the total number of moments from the last time the drying rod stopped to the current moment. The direction of the light offset can be determined based on the sum of these light intensity differences, SUM.

[0471] In this embodiment, when there are multiple groups of light sensors corresponding to multiple groups of positions on the clothes-drying rod, the sum of the light intensity differences can be calculated for each group of positions, and then the average is compared with the light threshold to determine the direction of light offset. In addition, if a group of light sensors includes more than three light sensors, that is, each group of positions includes more than three positions, then for each group of positions, the sum of the light intensity differences at the above-mentioned moments can be calculated for two positions that are in a vertical relationship, and finally the sum of the light intensity differences obtained above SUM can be calculated. a,b Take the average to get the total difference in light intensity SUM.

[0472] For example, as shown in Figure 4c, a group of light sensors includes light sensors A, B, and C, which are respectively set at positions a, b, and c on the clothes-drying rod. The sum of the light intensity differences SUM at the above moments can be calculated for two positions b and a that are in a vertical relationship. b,a , calculate the sum of the light intensity differences SUM at the above moments for the two positions c and b that have a vertical relationship c,b , SUM b,a and SUM c,b Take the average to get the total difference in light intensity SUM.

[0473] In this embodiment, after determining the direction of light offset, the controller controls the clothesline to rise or fall. When the light offset is downward, the controller controls the clothesline to fall, monitoring the light intensity on the clothesline in real time during the descent. If the light intensity detected on the clothesline is greater than a set value, such as 10,000 lux, the clothesline stops descending, with the stop position becoming the optimal drying position. When the light offset is upward, the controller controls the clothesline to rise, searching for a suitable drying position during the ascent. A suitable drying position can be a position where the light intensity is greater than the set value, or a position where the light intensity decreases from the maximum intensity. When the clothesline stops at this position, the clothesline remains at the position of maximum light intensity.

[0474] In summary, in this embodiment, by arranging at least two light sensors along the movement direction of the clothes drying rod, the total difference in light intensity at at least two upper and lower positions on the clothes drying rod can be determined, that is, the light change situation can be determined, and the light offset direction can be determined based on the light change situation, and then the clothes drying rod is controlled to move to a drying position that meets the conditions based on the light offset direction, thereby realizing continuous light chasing, so that the clothes drying on the clothes drying rod can always be in the best drying position, effectively improving the drying efficiency of the clothes drying machine.

[0475] The following is a detailed description of the clothes drying machine that is suitable for the drying and tracking light control system.

[0476] This embodiment discloses a clothes drying machine, comprising a main unit, a clothes drying rod, and a light-tracking control system provided in this embodiment. The clothes drying rod is attached to the main unit via a steel wire rope, which is automatically raised and lowered by a motor in the main unit. A control system is provided in the main unit to control the clothes drying machine to perform various other functions, including drying, disinfection, and lighting.

[0477] In this embodiment, as shown in FIG6 , the clothes drying machine controller is connected to an external terminal and / or a cloud platform via a networking module, which may be an IoT cloud platform. The clothes drying machine controller is connected to the internet via the networking module and can obtain real-time weather information, latitude and longitude information, network time, and the like.

[0478] The clothes drying machine of this embodiment can control the start or stop of light chasing according to weather change information based on the weather information obtained by the networking module. For example, during the light chasing process, when the weather changes from sunny to cloudy, the light chasing function can be controlled to be turned off to stop light chasing and control the clothes drying rod to be at the top position. After the weather turns sunny, the light chasing can be continued. Therefore, the system of the utility model can adapt to the changes in the weather and realize automatic light chasing control according to weather conditions.

[0479] In this embodiment, the clothes drying machine can determine the start and end time of the day at the clothes drying machine's installation location after obtaining the latitude and longitude information. Therefore, the light tracking function can be controlled to turn on when the current time reaches the start time of the day, and to turn off when the current time reaches the end time. This can automatically control the light tracking function based on time information, greatly facilitating the light tracking control of the clothes drying machine. In addition, obtaining time through the network can make the time determined by the clothes drying machine more accurate, and the control can also be more precise.

[0480] The following is a detailed description of the light-chasing clothes drying machine provided in the embodiment of the present application.

[0481] This section will describe the specific embodiments of the present application in detail. The preferred embodiments of the present application are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present application, but it cannot be understood as a limitation on the scope of protection of the present application.

[0482] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0483] 15 to 19 , a preferred embodiment of the light-tracking clothes drying machine of the present application includes:

[0484] Host 10,

[0485] Lifting devices 20 are provided on both sides of the main machine 10;

[0486] The drying rack 30 is used for drying clothes and is connected to the main unit 10 via the lifting device 20. It can be driven by the main unit 10 or driven to rise and fall.

[0487] The photosensitive module 40 is provided on the lifting device 20 and / or the drying rack 30, and is capable of sensing light and feeding back light information to the host. The host controls the drying rack 30 or the hook 311 of the drying rack 30 to reach the designated drying position according to the light information. By providing a photosensitive module on the lifting device and / or the drying rack, it is capable of sensing light and feeding back light information to the host. The host controls the drying rack or the hook of the drying rack to reach the designated drying position according to the light information, thereby allowing most of the surface of the clothes to be exposed to sunlight as much as possible or extending the exposure time to sunlight as much as possible. The drying rack 30 can be driven to rise and fall autonomously or by the host 10. The drying rack has its own motor to drive the steel wire rope to rise and fall, that is, the original host's built-in motor is transferred to the drying rack, so that the host can be reduced in size and made thinner. The photosensitive module 40 can be installed on the lifting device 20, on the drying rack 30, or on both the lifting device 20 and the drying rack 30. The following specifically describes the installation on the drying rack. It is understood that the embodiments of installing the photosensitive module 40 on the lifting device or on both the lifting device and the drying rack are equally applicable to achieve the same function. In this embodiment, the lifting device 20 is a folding frame that can prevent the drying rack from swinging back and forth.

[0488] Specifically, multiple photosensitive modules 40 are arranged in a spaced-apart arrangement. This spacing facilitates simultaneous horizontal and / or vertical sensing of light at multiple locations, thereby locating the location with the strongest light. Due to varying orientations and seasons, sunlight can have varying angles throughout the day. When the photosensitive modules are arranged in a horizontally spaced arrangement, they can sense changes in sunlight on the left and right sides of the balcony. When the photosensitive modules are arranged in a vertically spaced arrangement, they can sense changes in sunlight on the upper and lower sides of the balcony. When the photosensitive modules are distributed both horizontally and vertically, they can comprehensively sense changes in sunlight on the balcony.

[0489] The photosensitive module 40 can be movably connected to the drying rack 30, and compared with a fixed setting, it can sense more and more flexible positions. As described above, for example, if five photosensitive modules are arranged horizontally on the drying rack at intervals, the light information obtained by them is constant in the horizontal position (up to 5), and can only change in the vertical direction as the drying rack is raised or lowered (up to infinite). Therefore, its perceptible range is relatively small. If the photosensitive module is set to be movable on the drying rack, the light information obtained by it can be changed in the horizontal position (up to infinite). That is, only one photosensitive module is needed to realize the functions of multiple photosensitive modules. It is only necessary to sample at different time points with a short interval to obtain light information at multiple positions, and the sampling positions can be increased as needed.

[0490] In order to further realize the movable lighting function, the photosensitive module 40 is provided with a driving wheel, and the drying rod 31 is provided with a guide rail or guide groove 312 that matches the driving wheel.

[0491] In order to further illustrate the relationship between different drying rack shapes and the photosensitive module, the drying rack is expanded below.

[0492] In a typical drying rack, the drying rack 30 includes two spaced-apart drying rods 31 and a support frame 32 connecting the two drying rods 31. The photosensitive module 40 is movably mounted on the drying rod 31 on the sunny side. The drying rod on the sunny side is generally located on the side closer to the balcony or on the outside. Conversely, the side farther from the balcony, i.e., closer to the living room, is considered the inside. Positioning the photosensitive module on the sunny side facilitates unobstructed sunlight perception.

[0493] Furthermore, the drying rod 31 is movably connected to a plurality of hooks 311. These hooks are interconnected and can be brought together or dispersed by a motor. When the light-sensing module senses light at different positions on the drying rod, the host control system can control the drive mechanism to bring the hooks together or disperse to appropriate positions. For example, if the light-sensing module senses no light on the left side of the drying rod and light on the rear side, the drive mechanism will be controlled to bring the hooks together to the right side where the light is. If light is present on both sides and the intensity is comparable, the drive mechanism will be controlled to disperse the hooks. To achieve this function, a drive trolley can be installed at both ends of the hooks.

[0494] Furthermore, in order to realize the real-time linkage between the photosensitive module and the hook, the photosensitive module 40 can be arranged on one or more of the hooks 311. For example, when the hook is located at a position where it cannot sense light, it can feedback light information to the host in real time. The host controls the driving mechanism according to the feedback to drive the hook to a position with light.

[0495] The circular drying rack, as shown in Figures 15 to 17, adds two arcuate transition sections to a conventional drying rack. Specifically, a curved rod is connected to the same side of two spaced-apart drying rods 31 to form a circular drying rack. Multiple hooks 311 are movably connected to the circular drying rack 30. To allow for the hooks to move, the drying rods and the curved rods are hollow and connected, with slots at their lower ends for the hooks' hanging portions to extend. The hooks' movable portions move within the drying rods and the curved rods (not shown).

[0496] In this embodiment, a drive belt 313 is provided within the annular drying rack 30, and the hook 311 is connected to the drive belt. The drive belt is driven by a motor 34 and can rotate along the drying rack 30. When the light-sensing module senses light at different positions on the drying rod, the host control system can control the motor to move the hook to the appropriate position. The host control system can even adjust the drying time and position of each piece of clothing at different light intensities based on the light intensity. For example, heavier or wetter clothing can be dried longer in a stronger light intensity, while clothing of the same wetness or weight can be dried in the stronger light position in turn.

[0497] Similarly, the photosensitive modules 40 can be arranged in an arranged or spaced relationship on a plurality of the hooks 311 to achieve real-time linkage.

[0498] Of course, it is understandable that in the case of a circular drying rack, the hooks can also be driven by a driving trolley to separate or gather thereon to meet different drying needs.

[0499] Figures 15 to 17 of this embodiment illustrate a guide slot 312 defined in a circular drying rack. The photosensitive module is a light-chasing vehicle comprising a housing 41, a light-transmitting cover 42 protruding from the housing 41, at least one drive wheel 43 mounted on the bottom of the housing 41, a light-transmitting cover 42 housing a light detection chip 44, and a battery 45 and a control board 46 built into the housing 41. The drive wheel 43 is directly driven by a second motor 47 and can move along the guide slot 312.

[0500] In order to enable the light-chasing trolley to move continuously or intermittently on the annular drying rack, power-taking plates 48 are provided on both sides of the shell 41 , and correspondingly, power supply contacts (not shown) are provided inside the guide groove 312 .

[0501] To further sense the environment in which the clothes are located, the housing 41 is further provided with a humidity sensor or a raindrop sensor 49.
