Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a control method, device, medium, and clothes drying rack. Background Technology

[0002] With the development of smart home appliances, clothes drying racks equipped with lights have emerged to add brightness to balconies while clothes are being dried.

[0003] However, the total power and power distribution of existing clothes drying racks are fixed, i.e., total power = motor power + lighting power of lamps. For example, the rated total power of the power supply is 100W, of which the rated power of the motor is 80W and the rated power of the lighting is 20W. Since the lighting power of the lamps is fixed, it cannot be changed according to the actual situation of clothes drying, which can easily lead to problems such as insufficient brightness caused by clothes drying, causing inconvenience to users and reducing the user experience.

[0050] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0051] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0052] The clothes drying rack to which the technical solution provided in this disclosure applies is at least equipped with a power supply, a clothes drying rod, a lighting device, and a drive device. The lighting device can be a lamp, and the drive device can be a motor. The power supply is used to supply power to the lighting device and the drive device. The lighting device provides lighting function, and the drive device provides driving function for the clothes drying rod. Specifically, it drives the clothes drying rod to perform rising and falling movements to realize the height adjustment of the clothes drying rod, so that users can hang and take off clothes and other loads through the clothes drying rod.

[0053] In addition, the rotation direction of the drive device, such as the motor, is related to the movement direction of the clothes drying rod. Under normal circumstances, the motor rotates forward to drive the clothes drying rod to move upward, that is, the clothes drying rod rises, and the motor rotates in reverse to drive the clothes drying rod to move downward, that is, the clothes drying rod descends.

[0054] The control method, device, medium, and clothes drying machine provided in the embodiments of this disclosure will be described by way of example below with reference to the accompanying drawings.

[0055] Figure 1 This is a flowchart illustrating a control method for a clothes drying rack according to an embodiment of the present disclosure. This control method can be executed by a control device, such as the controller of the clothes drying rack. The control device can be implemented in software and / or hardware. (Refer to...) Figure 1 The method includes the following steps:

[0056] S110: Receive the lifting command and, in response to the lifting command, control the drive device to drive the clothes drying rod to perform the lifting action.

[0057] The "rise command" is used to instruct the clothesline to rise. Specifically, in response to the received rise command, the drive device is controlled to drive the clothesline to rise, increasing its vertical height. The load on the clothesline (such as clothes) moves synchronously with it, allowing the load to rise to a higher position for drying. It is easy to understand that the rising scenarios corresponding to the clothesline's rising action include: the start of rising, the process of rising, and the stopping of rising.

[0058] S120. Determine the first load parameters for the rising clothesline.

[0059] The first load parameter is used to characterize the amount of load on the rising clothesline. By determining the first load parameter of the rising clothesline, the amount of clothing on the rising clothesline can be further determined, which facilitates the adaptive adjustment of the lighting power of the lighting device based on the amount of clothing on the rising clothesline. The specific adjustment of the lighting power will be explained later.

[0060] S130. Determine the first lighting power based on the first load parameters.

[0061] The first lighting power is the expected power of the lighting device under the premise that the clothesline is rising. Specifically, the first lighting power is determined based on the amount of clothing on the rising clothesline, so that the lighting power of the lighting device can be dynamically adjusted according to the amount of clothing. For example, when there are more clothes, the lighting power increases and the brightness increases; when there are fewer clothes, the lighting power decreases and the brightness decreases. This satisfies the brightness requirements for drying various amounts of clothing and overcomes the limitation of fixed lighting power in existing clothes drying machines, such as lamps.

[0062] S140. Determine that the clothesline has stopped rising and adjust the lighting power of the lighting device to the first lighting power.

[0063] Specifically, as mentioned above, when the clothesline rises, the clothes rise accordingly for drying. However, as the height of the clothesline increases, it blocks light to some extent, reducing the brightness of the surrounding environment. This effect is most severe when the clothesline reaches its highest point. To address this, this embodiment of the present disclosure controls the lighting power of the lighting device to a first lighting power, providing the necessary brightness for drying a certain amount of clothing currently on the clothesline. This allows for higher brightness when the user needs to dry clothes, avoiding the problem of insufficient brightness caused by a fixed lighting power that cannot be dynamically adjusted.

[0064] Furthermore, the total power supply is the sum of the power of the lighting device (referring to lighting power) and the power of the drive device (referring to drive power). Based on this, if it is determined that the clothesline has stopped performing the upward movement, it indicates that the clothesline has risen to the designated height. At this time, adjusting the lighting power of the lighting device to the first lighting power can ensure that the drive power of the drive device itself is sufficient to support the clothesline to achieve a stable upward movement. This prevents the clothesline from being unable to rise to the designated height normally due to improper adjustment of the lighting power of the lighting device during the upward movement of the clothesline.

[0065] The control method for a clothes drying rack provided in this disclosure includes: receiving a lifting command and, in response to the lifting command, controlling a drive device to drive the clothes drying rod to perform a lifting action; determining a first load parameter of the lifting clothes drying rod; determining a first lighting power based on the first load parameter; determining that the clothes drying rod stops performing the lifting action, and adjusting the lighting power of the lighting device to the first lighting power. In this way, the lighting power is no longer fixed but is adjusted according to the load of the clothes drying rod, thereby bringing convenience to the user and improving the user experience.

[0066] In some embodiments, Figure 1 Based on this, S120 specifically includes the following steps:

[0067] Step 1: Obtain the motor operating current during the clothesline's ascent.

[0068] The motor operating current is the current consumed by the motor during operation, and it is related to the amount of clothing, reflecting the quantity of clothing. The quantity of clothing refers to its amount, specifically including weight and / or number.

[0069] Specifically, given the driving force exerted by the motor on the clothesline, the heavier and more numerous the clothes on the clothesline, the more energy the motor consumes, and the more severe the light blocking effect, resulting in a higher initial lighting power. Conversely, the lighter and fewer the clothes on the clothesline, the less energy the motor consumes, and the less light blocking effect, resulting in a lower initial lighting power.

[0070] Step 2: Use the motor operating current as the first load parameter.

[0071] Specifically, when clothes are hung on the clothesline and the clothesline rises, the higher the current of the motor, the more clothes there are, and the lower the current, the fewer clothes there are. This shows that there is a mapping relationship between the motor current and the weight and / or quantity of clothes. For example, the motor current corresponds one-to-one with the quantity of clothes. By substituting the motor current into this mapping relationship, the corresponding quantity of clothes can be determined.

[0072] Thus, by measuring the weight and / or quantity of clothes based on first load parameters such as motor operating current during the clothesline's ascent, this embodiment of the present disclosure can accurately determine the magnitude of the first lighting power, providing the required brightness specifically for the clothes currently being dried, without the need for additional weight sensors or other components, thereby reducing hardware application costs.

[0073] In other embodiments, the motor's operating voltage, power, or other operating parameters during the clothesline's ascent can be obtained as the first load parameter. Appropriate operating parameters can be selected based on the calculation requirements of the first lighting power, and are not limited here.

[0074] In some embodiments, obtaining the motor operating current during the clothesline's ascent process in the above steps specifically includes the following steps:

[0075] Step 1: Sample the operating current values ​​of multiple motors during the time the clothesline rises.

[0076] Specifically, by collecting the motor's operating current value during the clothesline's ascent and determining the initial lighting power when the clothesline stops rising, the system can further achieve precise control over the lighting power of the lighting device.

[0077] For example, during the time the clothesline rises, the motor operating current value can be collected at equal time intervals, such as once every one second or once every three seconds. Alternatively, the motor operating current value can be collected at different time intervals, such as once every one second and then once every two seconds, and this process can be repeated to obtain multiple motor operating current values. The sampling frequency of the motor operating current value can be set according to the actual calculation requirements, and is not limited here.

[0078] Step 2: Based on multiple motor operating current values, determine the average operating current value of the motor and use it as the motor operating current.

[0079] In this way, by averaging the operating current values ​​of multiple motors, the average operating current value is obtained and used as the motor operating current, making the motor operating current more representative, reducing the calculation error of the motor operating current, and thus improving the accuracy of subsequent calculation of the first lighting power.

[0080] In some embodiments, Figure 1 Based on this, S130 specifically includes the following steps:

[0081] Step 1: Obtain the rated minimum power and power parameters of the lighting.

[0082] The minimum rated power of the lighting is the minimum value of the set lighting power, denoted by PLmin. Specifically, the minimum rated power of the lighting = total power of the power supply - maximum rated power of the motor. This ensures that the lighting device maintains a certain brightness for illumination when the clothesline is under maximum load. Otherwise, if the lighting power exceeds the minimum rated power, the motor will be insufficient to drive the clothesline to rise. The maximum rated power of the motor is the power generated by the motor when the clothesline is raised under maximum load, also known as the full-load lifting power of the motor.

[0083] Among them, the lighting power parameter is greater than zero. For example, the lighting power parameter can be a range of lighting power between a certain value and a certain value. Specifically, the lighting power range is determined by the lower limit and the upper limit of lighting power. The lower limit of lighting power represents the minimum value of lighting power, and the upper limit of lighting power represents the maximum value of lighting power. It is easy to see that the lighting power of the lighting device is greater than or equal to the lower limit of lighting power and less than or equal to the upper limit of lighting power.

[0084] Step 2: Determine the first lighting power based on the first load parameters, the rated minimum power of the lighting, and the lighting power parameters.

[0085] The first load parameter, the minimum rated power of the lighting, the lighting power parameter, and the first lighting power are associated with a preset relationship. Specifically, by substituting the first load parameter, the minimum rated power of the lighting, and the lighting power parameter into the above preset relationship, the unknown quantity in the corresponding preset relationship, namely the first lighting power, can be determined. The specific process for determining the first lighting power will be explained exemplarily below.

[0086] For example, the preset association relationship may be a relevant lookup table, an association formula, or other forms of association relationship known to those skilled in the art, so as to determine the first lighting power through the preset association relationship, without limitation herein.

[0087] In some embodiments, obtaining the lighting power parameters in the above steps includes the following steps:

[0088] Step 1: Obtain the total power supply and the power reduction of the motor under full load.

[0089] The total power of the power supply is the total power that the power supply can provide, denoted by P. 总 The full-load descent power of a motor is the power generated when the motor descends under maximum load, denoted by P. a express.

[0090] Step 2: Determine the upper limit of lighting power based on the total power supply and the power reduction of the motor under full load.

[0091] Among them, the total power of the power supply, the power reduction of the motor under full load, and the upper limit of the lighting power are interrelated. Specifically, the difference between the total power of the power supply and the power reduction of the motor under full load is the upper limit of the lighting power. The upper limit of the lighting power can be obtained by subtracting the total power of the power supply and the power reduction of the motor under full load.

[0092] It should be noted that when the clothesline is lowered without load, the power generated by the motor is the no-load lowering power, which is less than the full-load lowering power. Correspondingly, the difference between the total power supply and the no-load lowering power is greater than the difference between the total power supply and the full-load lowering power. If the difference between the total power supply and the no-load lowering power is set as the maximum value of the lighting power, then when the lighting power is at this maximum value and the clothesline is fully loaded, the lighting power needs to be adjusted to P first. 总 - Pa is required for the motor to descend normally, which wastes some time and makes the clothes drying rack less smooth to use. Therefore, this embodiment of the disclosure sets P... 总 -Pa is the maximum set lighting power, so that the clothesline can still be lowered quickly when the lighting device is at its maximum brightness.

[0093] Step 3: Use the minimum rated power of the lighting as the lower limit of the lighting power.

[0094] Specifically, as mentioned above, the minimum rated power of the lighting is the minimum value of the set lighting power. By using the minimum rated power of the lighting as the lower limit of the lighting power, the lighting requirements when the clothes drying rack is under maximum load can be met, which is conducive to the normal use of the clothes drying machine.

[0095] Step 4: Determine the lighting power parameters based on the upper and lower limits of lighting power.

[0096] Specifically, based on the obtained upper and lower limits of lighting power, the range of lighting power defined by these two limits can be determined, which can be expressed as a difference, i.e., by subtracting the upper and lower limits of lighting power, we obtain P. 总 -Pa-PLmin, so that the first lighting power can be determined based on this range of values.

[0097] In some embodiments, the first load parameters include the motor operating current and the motor rated maximum current; the preset correlation for determining the first lighting power includes a correlation formula; the correlation formula is:

[0098]

[0099] Where P1 represents the first lighting power, P Lmin Indicates the minimum rated power of the lighting, I a I represents the motor's operating current. max P represents the rated maximum current of the motor, which is the current corresponding to the rated maximum power of the motor. 总 P represents the total power of the power supply. a This indicates that the motor's power decreases when fully loaded.

[0100] Specifically, by combining the correlation formula, the ratio of the motor operating current to the motor's rated maximum current is multiplied by the lighting power range to obtain a certain proportion of the value within that lighting power range. The larger the motor operating current, the larger this value, and vice versa. Adding this value to the rated minimum lighting power gives the first lighting power. Since the motor operating current is related to the amount of clothing, the first lighting power is adjusted according to the amount of clothing, ensuring that the ambient brightness (i.e., space brightness) is adaptively changed. Thus, even when there are many clothes to dry, the space brightness can still meet the user's needs.

[0101] Furthermore, in the related formulas, the total power supply, the minimum rated power of the lighting, the maximum rated current of the motor, and the power reduction under full load of the motor are usually values ​​set at the factory when the clothes dryer leaves the factory. These values ​​can vary depending on the design parameters of the clothes dryer. For example, P... 总 It can be 84W, P Lmin The rated power can be 24W, and the maximum rated power of the motor can be 60W. The value of the relevant parameters in the related formula is not limited here.

[0102] In some embodiments, Figure 2 This is a flowchart illustrating another control method for a clothes drying rack provided in an embodiment of this disclosure. (Refer to...) Figure 2 The method may include the following steps:

[0103] S201. Confirm that the clothesline is raised.

[0104] The rising of the clothesline usually indicates that the motor is rotating in the forward direction. By obtaining the direction of the motor's rotation, it can be determined whether the clothesline has responded to the rising command and performed the rising action.

[0105] S202, Collect the motor operating current.

[0106] Specifically, by collecting the motor's operating current under the premise of determining the clothesline's ascent, the weight and / or quantity of clothes on the clothesline can be further estimated, thereby determining the magnitude of the first lighting power. This ensures that when there are many clothes to dry, the first lighting power is greater and the brightness of the lighting device is higher, thus enhancing the brightness of the space. Conversely, when there are fewer clothes to dry, the first lighting power is lower and the brightness of the lighting device is lower, ensuring sufficient brightness of the space while saving energy.

[0107] S203. Has the motor stopped running?

[0108] Determine if the motor has stopped running. If yes, execute S204; otherwise, execute S202.

[0109] S204. The lighting power is adjusted according to the motor operating current during the clothes drying rod's ascent.

[0110] Specifically, when the motor stops running, the clothesline stops rising. By combining the motor's operating current during the previous rising process, a highly accurate first lighting power can be calculated. Based on this, the lighting power of the lighting device is adjusted to the first lighting power, which helps to bring a better user experience and meet the user's brightness needs for drying clothes.

[0111] In some embodiments, the method further includes the following steps:

[0112] Step 1: Receive the descent command and respond to the descent command by controlling the drive device to drive the clothesline to perform the descent action.

[0113] The descent command is used to instruct the clothesline to lower itself. Specifically, in response to the received descent command, the drive device is controlled to lower the clothesline, reducing its vertical height. The load on the clothesline (such as clothes) moves synchronously with this lowering, making it easier for the user to retrieve. It's easy to understand that the descent scenarios include: the start of descent, the process of descent, and the stop of descent.

[0114] Step 2: Determine the second load parameters for the lowered clothesline.

[0115] The second load parameter is used to characterize the amount of load on the descending clothesline. By determining the second load parameter of the descending clothesline, the amount of clothing on the descending clothesline can be further determined, thus facilitating the adaptive adjustment of the lighting power of the lighting device based on the amount of clothing on the descending clothesline. The specific adjustment of the lighting power will be explained later.

[0116] Step 3: Determine the second lighting power based on the second load parameters.

[0117] The second lighting power is the expected power of the lighting device under the premise that the clothesline is lowering. Specifically, by determining the second lighting power based on the amount of clothing on the lowered clothesline, the lighting power of the lighting device can be dynamically adjusted according to the amount of clothing, overcoming the limitation of fixed lighting power in existing clothes drying machines.

[0118] Step 4: Once the clothesline has stopped descending, adjust the lighting power of the lighting device to the second lighting power.

[0119] Specifically, as the clothesline descends, the clothes reduce their obstruction of light, increasing the brightness of the surrounding environment. When the clothesline stops descending, the lighting power of the lighting device can be adjusted to a lower secondary lighting power. This allows the lighting device to provide a lower but appropriate brightness when the user needs to retrieve clothes, saving energy while avoiding visual discomfort caused by high brightness.

[0120] In some embodiments, the second load parameter includes the rated minimum power of the lighting; the steps above for determining the second lighting power based on the second load parameter include the following steps:

[0121] The minimum rated power of the lighting is taken as the second lighting power.

[0122] For example, the lighting power of the lighting device can be adjusted during the descent of the clothesline, or when the clothesline stops descending. Taking the former as an example, during the descent of the clothesline, the lighting power of the lighting device can be controlled to gradually decrease from a first lighting power to a second lighting power. The amount of power change within a preset time and the specific timing of power adjustment can be set according to the brightness adjustment requirements. It is only necessary to ensure that the lighting power of the lighting device is the minimum rated lighting power when the clothesline stops descending. There are no limitations on either of these.

[0123] In this way, by using the minimum rated power of the lighting as the second lighting power, it is possible to ensure that the drive device, such as the motor itself, has enough power to drive the clothes drying rod and the clothes it carries to rise together when the clothes drying rod continues to rise. This improves the stability and reliability of the clothes drying machine during operation, and thus helps to enhance the user experience.

[0124] In some embodiments, Figure 3 A flowchart illustrating another control method for a clothes drying rack provided in this disclosure embodiment is shown below. Figure 3 The method includes the following steps:

[0125] S301. Confirm that the clothesline has been lowered.

[0126] The clothesline descending usually indicates that the motor is reversing. By obtaining the direction of the motor's rotation, it can be determined whether the clothesline is responding to the descent command and performing a descent action.

[0127] S302, Lighting power is reduced to the minimum rated lighting power.

[0128] Specifically, the lighting power is typically reduced to the minimum rated power during or after the clothesline is lowered. For example, the minimum rated power can be 10W, 20W, 24W, or other values, and can be set according to the actual situation of the clothesline; this is not limited here.

[0129] It is understandable that in other embodiments, although the motor operating current can be obtained during the descent of the clothesline to calculate the second lighting power, the resistance needs to be constantly adjusted to slow down the descent speed to achieve a slow descent and prevent free fall. This is equivalent to the motor not doing any work, resulting in large fluctuations in the motor operating current and high measurement errors. When the clothesline rises, it only needs to overcome gravity to achieve a smooth rise, and the change in the motor operating current is gradual, with smaller measurement errors. Therefore, compared to obtaining the motor operating current during the descent of the clothesline, the calculation method of obtaining the motor operating current during the rise of the clothesline in this embodiment is more accurate.

[0130] Based on the above embodiments and the same inventive concept, this disclosure also provides a brightness control device.

[0131] In some embodiments, Figure 4 This is a schematic diagram of the structure of a control device for a clothes drying rack provided in an embodiment of this disclosure. (Refer to...) Figure 4 The control device includes: an action drive module 41, for receiving a lifting command and controlling the drive device to drive the clothesline to perform a lifting action in response to the lifting command; a first determination module 42, for determining a first load parameter of the lifting clothesline; a second determination module 43, for determining a first lighting power based on the first load parameter; and a power adjustment module 44, for determining that the clothesline stops performing the lifting action and adjusting the lighting power of the lighting device to the first lighting power.

[0132] Specifically, in the control device of the clothes drying rack provided in this embodiment, through the coordinated action of the action drive module 41, the first determination module 42, the second determination module 43, and the power adjustment module 44, the clothes drying rod can be driven to perform an upward action in response to the received upward command. The first load parameter of the upward clothes drying rod is determined, and the amount of clothes on the upward clothes drying rod is determined by the first load parameter. This facilitates the adaptive adjustment of the lighting power of the lighting device according to the amount of clothes on the upward clothes drying rod. That is, the first lighting power is determined based on the first load parameter. When there are more clothes, the first lighting power is relatively large, and the brightness is increased; when there are fewer clothes, the first lighting power is relatively small, and the brightness is reduced. This satisfies the brightness requirements when drying various amounts of clothes. Furthermore, when it is determined that the clothes drying rod stops performing the upward action, the lighting power of the lighting device is adjusted to the first lighting power. This ensures that the drive power of the drive device itself is sufficient to support the clothes drying rod to achieve a stable upward effect, while providing the brightness required for drying clothes on the clothes drying rod suspended at a high position.

[0133] It is understood that the control device for the clothes drying rack provided in this embodiment can implement the steps of any of the control methods for the clothes drying rack provided in the above embodiments, and has corresponding beneficial effects, which will not be elaborated here.

[0134] This disclosure also provides a computer-readable storage medium having a computer program stored thereon, the computer program being executed by a processor to implement the steps of any of the clothes drying rack control methods provided in the above embodiments.

[0135] The computer-readable storage medium may be any combination of one or more readable media. A readable medium may be a readable signal medium or a readable storage medium. A readable storage medium may be, for example, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination thereof.

[0136] This disclosure also provides a clothes drying rack. Exemplarily, Figure 5 This is a schematic diagram of the structure of a clothes drying rack provided in an embodiment of the present disclosure, with reference to... Figure 5 The clothes drying rack includes a clothes drying rod 50, a drive device 51, a lighting device 52, a memory 53, and a processor 54; the memory 53 stores executable programs or instructions; the processor 54 runs the programs or instructions to implement the steps of any of the clothes drying rack control methods provided in the above embodiments.

[0137] Specifically, the drive device 51 can be controlled to drive the clothes drying rod 50 to perform an upward action according to the upward command. Then, the first load parameter of the upward clothes drying rod 50 is determined, and the first lighting power required for drying the current clothes is determined based on this. When the clothes drying rod 50 stops performing the upward action, the lighting device 52 is increased to the first lighting power, so as to realize the adaptive adjustment of the lighting power of the lighting device according to the condition of the clothes. The lighting power of the lighting device is no longer fixed.

[0138] The processor 54 may be a central processing unit (CPU) or other form of processing unit with data processing and / or instruction execution capabilities, and may control other components in the computer to perform desired functions.

[0139] The memory 53 may include one or more computer program products, which may include various forms of computer-readable storage media, such as volatile memory and / or non-volatile memory. Volatile memory may include, for example, random access memory (RAM) and / or cache memory. Non-volatile memory may include, for example, read-only memory (ROM), hard disk, flash memory, etc. One or more computer program instructions may be stored on the computer-readable storage medium, and the processor 54 may execute these program instructions to implement the method steps of the various embodiments of this application described above and / or other desired functions.

[0140] In some embodiments, Figure 6 This is a schematic diagram of another clothes drying rack provided in an embodiment of this disclosure. (Refer to...) Figure 6 The clothes drying rack includes: a power supply 55, a DC-DC conversion circuit 56, a controller 57, a drive unit 51, and a lighting device 52; the power supply 55 is connected to the DC-DC conversion circuit 56, the drive unit 51, and the lighting device 52 respectively, and the controller 57 is connected to the DC-DC conversion circuit 56, the drive unit 51, and the lighting device 52 respectively, and the direction of transmission of relevant energy or signals is indicated by arrows.

[0141] The power supply 55 is an AC-DC power supply, used to convert alternating current into direct current to provide DC power to connected electrical structures such as the drive unit 51 and the lighting unit 52, and to provide the DC-DC conversion circuit 56 with the required DC power. Furthermore, the power of the drive unit and the lighting power of the lighting unit are dynamically adjusted values, only requiring that the total power of the power supply be the sum of the power of the drive unit and the lighting power of the lighting unit.

[0142] The DC-DC converter circuit 56 converts the input DC power into a DC voltage of a corresponding magnitude to meet the power requirements of certain electronic components such as the controller 57. For example, the controller 57 can be used with voltages of 5V, 12V, 24V, or other magnitudes, which can be set according to actual needs and are not limited herein.

[0143] Among them, combined Figure 5 and Figure 6 The controller 57 includes a processor 54, which can execute instructions and process data. Specifically, in practical applications, the clothes drying rack also includes a drive device drive circuit and a lighting device drive circuit (not shown in the figure). The drive device drive circuit is used to drive the drive device 51 to work, including but not limited to controlling the power, speed, start and stop of the drive device 51. The lighting device drive circuit is used to drive the lighting device 52 to work, including but not limited to controlling the power, brightness, and on / off of the lighting device 52. Based on this, the controller 57 can sample the current of the drive device 51 through the drive device drive circuit, such as collecting multiple current values ​​of the drive device 51 during the rising time of the clothes drying rod 50, calculating the average current value as its working current, and the controller 57 sends a brightness adjustment signal to the lighting device drive circuit, which then responds to the brightness adjustment signal and makes adaptive adjustments to the lighting power of the lighting device.

[0144] It is easy to understand that there is a correlation between the power of a component and its application cost. Specifically, the higher the power of a component, the higher the application cost, and vice versa. Given that the total power of the power supply in this embodiment is constant, it can be seen that the overall cost of the power supply has not changed. Based on this, when the clothesline is raised, the lighting power of the lighting device is higher than the rated lighting power of the existing lighting device to avoid insufficient brightness caused by clothing blocking the light. Therefore, this embodiment increases the number of LEDs in the lighting device accordingly, achieving a good improvement in lighting brightness while ensuring a low overall application cost.

[0145] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0146] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
