Description

Technical Field

[0001] This application relates to the field of clothes drying control technology, specifically to a clothes drying machine and its working method, electronic equipment and storage medium. Background Technology

[0002] Electric clothes drying racks are increasingly popular due to their automatic lifting and lowering capabilities, as well as integrated functions such as lighting, drying, and sterilization. They have become an indispensable part of smart home products.

[0003] Currently, electric clothes drying racks feature diverse structural designs. The number of drying rods varies depending on the area and volume of drying required. For narrower drying areas, racks typically have one or more vertically arranged rods. To accommodate most households, racks usually have at least two parallel rods. Furthermore, the main unit is designed in different sizes, including varying lengths and widths, to suit different installation scenarios. For example, when installed in a narrow ceiling or when the main unit needs to be concealed by a suspended ceiling, it is usually designed to be narrower.

[0004] Clothes drying racks typically have their drying rods mounted below the main unit via a telescopic or folding lifting mechanism that allows them to move up and down relative to the main unit. To ensure the overall integrity of the drying rack and due to the size of the main unit, the design of the drying rods needs to be coordinated with the shape and size of the main unit. When the width of the main unit is relatively narrow, the spacing between the drying rods will also be relatively narrow for drying racks with multiple parallel drying rods. This will cause clothes on adjacent drying rods to collide with each other, affecting the amount of clothes that can be dried and making the drying efficiency lower. Summary of the Invention

[0005] The primary objective of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a clothes drying rack that can automatically adjust the spacing between the drying rods, thus avoiding the situation in the prior art where the spacing between the drying rods is too small due to the constraint of the main unit, causing clothes to collide with each other. This ensures the drying capacity and efficiency of the clothes drying rack while also maintaining the overall appearance of the rack.

[0006] The second objective of this invention is to provide a working method for a clothes drying rack. This method allows the spacing between the drying rods to be increased during the drying process, preventing clothes from colliding on different rods. At the same time, when the clothes drying rack is not in use, the spacing between the drying rods can be adjusted to fit the size of the main unit, ensuring the overall appearance of the clothes drying rack.

[0007] A third objective of this invention is to provide an electronic device.

[0008] A fourth objective of this invention is to provide a computer-readable storage medium.

[0009] The first objective of this invention is achieved through the following technical solution: a clothes drying rack, comprising a main unit, a lifting mechanism, a support frame, and a drying rod;

[0010] The drying rod is mounted on the bracket and connected to the main unit through a lifting mechanism, and moves up and down under the drive of the lifting mechanism;

[0011] The support structure is retractable.

[0012] The drying rod is installed at the telescopic end of the bracket; after the drying rod starts its descent and ascent, the bracket can telescopically move the drying rod to the first position and the second position respectively.

[0013] The spacing between the drying rods when they are in the first position is greater than the spacing when they are in the second position.

[0014] Preferably, the support includes a telescopic bracket, which is connected to the main unit via a lifting mechanism; the drying rod is disposed at the telescopic end of the telescopic bracket.

[0015] The telescopic bracket includes a fixed rod and a movable rod. The movable rod includes a first movable rod and a second movable rod disposed at both ends of the fixed rod and capable of telescopic movement relative to the fixed rod. The ends of the first movable rod and the second movable rod away from the fixed rod serve as the telescopic ends of the telescopic bracket.

[0016] A sliding member is provided at one end of the lifting mechanism connected to the telescopic bracket. When the lifting mechanism drives the telescopic bracket to move up and down, the sliding member slides on the telescopic bracket.

[0017] The sliding member is connected to the first movable rod and the second movable rod through a linkage mechanism, and is used to drive the first movable rod and the second movable rod to perform telescopic movement relative to the fixed rod.

[0018] Furthermore, the linkage mechanism includes a first rack, a first transmission gear, and a second rack;

[0019] The first rack is connected to the sliding member; the first transmission gear is rotatably mounted on the bracket and meshes with the first rack; the second rack is mounted on the movable rod and meshes with the first transmission gear, and the second rack extends along the direction of extension and retraction of the movable rod.

[0020] Furthermore, the sliding member abuts against the linkage mechanism along the first direction, and during the movement of the sliding member along the first direction, the sliding member drives the movable rod to extend through the linkage mechanism;

[0021] An elastic element is provided between the fixed rod and the movable rod, and the elastic element is used to continuously apply an elastic force to the movable rod in the direction of movement toward the fixed rod.

[0022] Furthermore, a locking mechanism is provided between the movable rod and the fixed rod, and the fixed rod can lock the movable rod through the locking mechanism;

[0023] During the movement of the slider in the first direction, the anti-reverse mechanism changes from being touched by the slider to being disengaged from the slider, that is, from the unlocked state to the locked state; when the anti-reverse mechanism is in the unlocked state, the slider drives the movable rod to extend through the linkage mechanism.

[0024] During the movement of the slider in the second direction, the anti-reverse mechanism changes from being disengaged from the slider to being touched by the slider, that is, from being locked to being unlocked. When the anti-reverse mechanism is in the unlocked state, the movable rod retracts under the action of the elastic element to retract into the fixed rod.

[0025] Preferably, the bracket includes a fixed rod and a first movable rod and a second movable rod disposed at both ends of the fixed rod and capable of telescopic movement relative to the fixed rod; the ends of the first movable rod and the second movable rod away from the fixed rod serve as the telescopic ends of the bracket and are used to connect the drying rod.

[0026] The bracket is equipped with a controller and a drive device. The controller is connected to the drive device, and the drive device is connected to the first movable rod and the second movable rod, which are used to drive the first movable rod and the second movable rod to perform telescopic movement relative to the fixed rod.

[0027] Furthermore, the controller communicates with the main controller on the host and / or an external terminal to receive telescopic commands sent by the main controller and / or the external terminal, so as to control the bracket to perform telescopic movement through the drive device.

[0028] The second objective of this invention is achieved through the following technical solution: a method for operating the clothes drying rack described in the first objective of this invention, comprising:

[0029] Control the clothes drying rack rod to descend;

[0030] After the clothes drying rack rod descent movement is initiated, the bracket is driven to extend, so that the drying rod at the extension end of the bracket changes to the first position;

[0031] Control the clothes drying rack rod to move upward;

[0032] After the clothes drying rack rod starts its upward movement, it drives the bracket to retract, causing the drying rod at the telescopic end of the bracket to change to the second position.

[0033] Preferably, the following steps are also included:

[0034] After the clothes drying rack starts its upward movement, it detects whether there are clothes drying on the drying rack.

[0035] If so, the support frame will not be driven to retract, and the position of the drying rod will be acquired in real time. When the drying rod rises to the drying position, the drying rod will be controlled to stop rising.

[0036] If not, the drive bracket will extend or retract, so that the drying rack changes to the second position when or before it rises to the first preset position;

[0037] The drying position is the position where the drying rod stops when the clothes are drying on the clothes drying machine, which is a preset distance away from the upper limit position or the storage position of the drying rod.

[0038] Furthermore, after the clothes drying rack's upward movement is initiated, if no clothes are detected on the drying rack, then:

[0039] The drive bracket extends and retracts synchronously during the upward movement of the drying rod, that is, it controls the position change of the drying rod synchronously during the upward movement, so that the drying rod changes to the second position when or before it rises to the first preset position.

[0040] or,

[0041] The position of the drying rod is acquired in real time. After the drying rod moves to the drying position, the support is driven to extend and retract, so that the drying rod changes to the second position when or before it rises to the first preset position.

[0042] Furthermore, the following steps are also included:

[0043] Detect whether there are clothes drying on the clothesline or whether the clothesline is below the drying position when the clothesline descent movement starts;

[0044] If so, the support frame will not be driven to extend after the drying pole descent movement is initiated;

[0045] If not, the drying rack will extend after the descent motion is initiated, causing the drying rack to change to the first position when or before it descends to the second preset position.

[0046] The third objective of this invention is achieved through the following technical solution: an electronic device, comprising: at least one processor, and a memory communicatively connected to the at least one processor, wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the following steps:

[0047] Obtain a control command for the clothes drying rack to lower the drying rod, and control the drying rod to lower.

[0048] After receiving the descent control command, a support extension movement command is generated to control the support to extend, so that the drying rod connected to the telescopic end of the support changes to the first position.

[0049] Obtain a control command to raise the clothes drying rack rod, and control the drying rack rod to move downwards;

[0050] After receiving the lifting control command, a support retraction movement command is generated to control the support to retract, so that the drying rod at the telescopic end of the support changes to the second position.

[0051] The clothes drying rack is connected to the main unit of the clothes drying rack via a lifting mechanism after the clothes drying rack is connected to the bracket. The spacing of the clothes drying rack when it is in the first position is greater than the spacing of the clothes drying rack when it is in the second position.

[0052] The fourth objective of this invention is achieved through the following technical solution: a computer-readable storage medium storing a computer program thereon, wherein the computer program, when executed by a processor, performs the following steps:

[0053] Obtain a control command for the clothes drying rack to lower the drying rod, and control the drying rod to lower.

[0054] After receiving the descent control command, a support extension movement command is generated to control the support to extend, so that the drying rod at the telescopic end of the support changes to the first position.

[0055] Obtain a control command to raise the clothes drying rack rod, and control the drying rack rod to move downwards;

[0056] After receiving the lifting control command, a support retraction movement command is generated to control the support to retract, so that the drying rod at the telescopic end of the support changes to the second position.

[0057] The clothes drying rack is connected to the main unit of the clothes drying rack via a lifting mechanism after the clothes drying rack is connected to the bracket. The spacing of the clothes drying rack when it is in the first position is greater than the spacing of the clothes drying rack when it is in the second position.

[0058] The present invention has the following advantages and effects compared with the prior art:

[0059] (1) The clothes drying rack of the present invention includes a main unit, a lifting mechanism, a support frame, and drying rods; the drying rods are mounted on the support frame and connected to the main unit through the lifting mechanism, and move up and down under the drive of the lifting mechanism; in the present invention, the support frame is a telescopic structure, and the drying rods are mounted on the telescopic end of the support frame; after the drying rods start to descend and ascend, the support frame can change the drying rods to a first position and a second position respectively through telescopic movement; wherein, the distance between the drying rods in the first position is greater than the distance between the drying rods in the second position. The present invention, based on the telescopic structure of the support frame, can automatically adjust the distance between the drying rods. Specifically, it can control the distance between the drying rods to increase after the drying rods descend and control the distance between the drying rods to decrease when the drying rods ascend, avoiding the situation in the prior art where the distance between the drying rods is too small due to the constraint of the main unit, resulting in the clothes colliding with each other. This ensures the drying capacity and drying efficiency of the clothes drying rack while also taking into account the overall appearance of the clothes drying rack.

[0060] (2) In the clothes drying rack of the present invention, the support can be a telescopic bracket connected to the lifting mechanism, that is, the drying rod is connected to the main unit through the telescopic bracket and the lifting mechanism, and the drying rod is set at the telescopic end of the telescopic bracket; the telescopic bracket includes a fixed rod and a first movable rod and a second movable rod set at both ends of the fixed rod, the ends of the first movable rod and the second movable rod away from the fixed rod serve as the telescopic end of the telescopic bracket, and are respectively connected to the drying rod; wherein, a sliding member is provided at the end of the lifting mechanism connected to the telescopic bracket, and the sliding member is connected to the first movable rod and the second movable rod through a linkage mechanism. When the lifting mechanism drives the telescopic bracket to move up and down, the sliding member can slide on the bracket, thereby driving the first movable rod and the second movable rod to move up and down relative to the fixed rod. Based on this, the present invention can drive the telescopic bracket to move up and down by only the lifting movement of the lifting mechanism, and can realize the control of the spacing between the drying rods without setting up additional power equipment, thus achieving effective energy saving and consumption reduction.

[0061] (3) In the clothes drying rack of the present invention, the support frame can also be controlled to extend and retract via a drive device mounted thereon. Specifically, the support frame can include a fixed rod and a first movable rod and a second movable rod disposed at both ends of the fixed rod; the ends of the first movable rod and the second movable rod away from the fixed rod serve as the extension and retraction ends of the support frame to connect to the drying rod; the support frame is equipped with a power system such as a controller and a drive device, the controller is connected to the drive device, and the drive device is connected to the first movable rod and the second movable rod, for driving the first movable rod and the second movable rod to extend and retract relative to the fixed rod. Based on this, the present invention can achieve extension and retraction via a drive device on the support frame, such as a motor or a telescopic cylinder. Since the drive device operates under the control of the controller, the corresponding drive commands can be flexibly adjusted based on the controller, making the control of the extension and retraction of the support frame more flexible.

[0062] (4) In the clothes drying machine of the present invention, the controller installed on the bracket can also communicate with the main controller on the clothes drying machine host and / or external terminals (such as mobile phones). Based on this, relevant operators can realize the telescopic movement control of the bracket through external terminals that communicate with the controller, external terminals connected to the main controller, or back-end platforms, which effectively improves the controllability of the clothes drying machine and can also adapt to more personalized needs.

[0063] (5) The working method of the clothes drying rack of the present invention is as follows: after the clothes drying rod descent movement is initiated, the support is driven to extend, so that the clothes drying rod at the telescopic end of the support changes to the first position; after the clothes drying rod descent movement is initiated, the support is driven to retract, so that the clothes drying rod at the telescopic end of the support changes to the second position. Compared with the second position, the spacing of the clothes drying rods is larger in the first position. The method of the present invention can make the spacing of the clothes drying rods larger after the clothes drying rack descends, so as to adapt to the drying distance and increase the drying capacity; at the same time, it can make the spacing of the clothes drying rods smaller after the clothes drying rack rises, so as to match the appearance of the main unit, for example, by retracting it onto the main unit.

[0064] (6) In the working method of the clothes drying rack of the present invention, after the upward movement of the drying rod is started, it is first detected whether there are clothes drying on the drying rod. If there are clothes, the control bracket does not retract. When the drying rod moves to the drying position, the control bracket stops the upward movement. The above operation ensures that when there are clothes drying on the drying rod, the drying rod remains in the first position when it rises to the drying position, thus maximizing the gap. When there are no clothes drying on the drying rod, the control bracket continues to rise, and the drying rod changes to the second position before rising to the first preset position (such as the storage position), thereby ensuring that the drying rod is in a smaller gap when it is retracted to the main unit, which is convenient for storage and is suitable for scenarios with a small main unit or hidden ceiling installation.

[0065] (7) The working method of the clothes drying rack of the present invention further includes the following operation: when the clothes drying rod descent movement is started, it is detected whether there are clothes drying on the clothes drying rod, or whether the clothes drying rod is in or below the drying position. If so, it is determined that the clothes drying rack is in the drying state and the clothes drying rod is currently in the first position. Therefore, after the clothes drying rod descent movement is started, the support is not driven to retract. Otherwise, it is determined that the clothes drying rod starts to descend from above the drying position and the clothes drying rack is not in the drying state. Therefore, after the clothes drying rod descent movement is started, the support is driven to extend, so that the clothes drying rod changes to the first position before descending to the second preset position. The above operation can avoid the operation of frequently adjusting the spacing of the clothes drying rod, that is, avoid unnecessary adjustment of the spacing of the clothes drying rod, and can effectively reduce the working power consumption of the clothes drying rack.

[0071] The embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions of the embodiments of this application.

[0072] Example 1

[0073] A clothes drying rack typically consists of a main unit and a drying rod. The main unit is usually mounted on the ceiling and contains a main controller, a power system, and other components. The power system may include a motor, a reel, a pulley assembly, and a steel wire rope. The main controller is connected to the motor via a motor driver to control the motor's rotation. The reel is driven by the motor's output shaft. One end of the steel wire rope is mounted on the reel, and the other end passes through a pulley in the pulley assembly to change direction (from horizontal to vertical) and is fixedly connected to the drying rod below the main unit. The reel rotates under the motor's power to wind up and unwind the steel wire rope, thereby causing the drying rod assembly on the steel wire rope to rise or fall. To prevent the drying rod from swaying due to airflow and for safety reasons, a lifting mechanism, such as a folding frame or a scissor frame, is usually installed between the drying rod and the main unit. Alternatively, some clothes drying racks do not have a winding component like a steel wire rope; instead, the drying rod and main unit are directly connected by a lifting mechanism, and the drying rod moves up and down with the lifting mechanism.

[0074] Clothes drying racks typically include one or more clothes drying rods for drying clothes, one or more quilt drying rods for drying bedding, and one or more horizontal rods for drying small items (underwear, socks, towels, etc.). In addition, clothes drying racks may also be equipped with lighting, drying, and disinfection modules, which can be controlled by a main controller.

[0075] Currently, clothes drying racks are usually installed below the main unit via a lifting mechanism and can move up and down relative to the main unit. To ensure the integrity of the clothes drying rack and due to the size of the main unit, the design of the drying rack needs to match the shape and size of the main unit. When the width of the main unit is relatively narrow, the spacing between the drying racks will also be relatively narrow for clothes drying racks with multiple parallel drying racks. This will cause clothes on adjacent drying racks to collide with each other, affecting the amount of clothes that can be dried and making the drying efficiency lower.

[0076] Based on the problems existing in the prior art, this embodiment provides a clothes drying rack, such as... Figure 1 As shown, the clothes drying rack includes a main unit 1, a lifting mechanism 2, a support frame 3, and a drying rod 4.

[0077] In this embodiment, the drying rod is mounted on the bracket and connected to the main unit through a lifting mechanism, and moves up and down under the drive of the lifting mechanism; in this embodiment, there are two or more drying rods.

[0078] In this embodiment, the support frame is a telescopic structure, and the drying rods are located at the telescopic end of the support frame. After the drying rods initiate their lowering and raising movements, the support frame can telescopically change the drying rods to a first position and a second position respectively. The spacing between the drying rods in the first position is greater than the spacing between the drying rods in the second position. In this embodiment, the specific spacing between the drying rods in the first and second positions can be set according to actual needs, such as ensuring good overall integration with the main unit when the drying rods are folded or that they can be well concealed, and preventing clothes on different drying rods from colliding when the drying rods are unfolded.

[0079] In this embodiment, the support includes a telescopic bracket. When there are multiple drying rods, such as two (first drying rod and second drying rod), the telescopic bracket is positioned between the two parallel drying rods. The number of telescopic brackets is typically set to multiple, such as two. When there are two, the two telescopic brackets are located at opposite ends of the main unit and are parallel to each other. The two telescopic ends of each bracket are connected to one end of each of the two drying rods. The two telescopic brackets and the two drying rods form a square frame structure. Additionally, one end of the telescopic bracket is connected to a lifting mechanism, and the other end of the lifting mechanism is connected to the main unit. The lifting mechanism moves up and down under the drive of a power device such as a wire rope, thereby causing the drying rods on the telescopic bracket to also move up and down.

[0080] In this embodiment, the telescopic bracket includes a fixed rod and a movable rod. The movable rod includes a first movable rod and a second movable rod disposed at both ends of the fixed rod and movable relative to the fixed rod. The ends of the first and second movable rods away from the fixed rod serve as the telescopic ends of the telescopic bracket and are respectively connected to the drying rod. In this embodiment, a sliding member is provided at one end of the lifting mechanism connected to the telescopic bracket. When the lifting mechanism drives the telescopic bracket to move up and down, the sliding member slides on the telescopic bracket. The sliding member is connected to the first and second movable rods through a linkage mechanism to drive the first and second movable rods to move telescopically relative to the fixed rod.

[0081] In this embodiment, the lifting mechanism can be a folding frame or a scissor frame, etc. One end of the folding frame or scissor frame connected to the telescopic bracket is provided with a sliding element, such as a slider or pulley. Usually, sliding elements are respectively provided on the two cross support rods at the bottom of the folding frame or scissor frame. The sliding elements are limited in the slide groove of the telescopic bracket. When the folding frame or scissor frame is folded or unfolded during the lifting movement, it drives the sliding elements to move linearly in the slide groove of the telescopic bracket. Specifically, when folding, the two cross support rods drive the sliding blocks on them to move away from each other in the slide groove. When unfolding, the two cross support rods drive the sliding elements on them to move closer to each other in the slide groove.

[0082] In this embodiment, the linkage mechanism between the sliding member 30 and the first and second movable rods can be implemented using linkage components such as gears and racks. When the folding frame or scissor frame folds and causes the drying rod to rise, the sliding members on the telescopic bracket move away from each other. Through the linkage mechanism, the first and second movable rods retract into the fixed rod. When the folding frame or scissor frame folds and causes the drying rod to descend, the sliding members on the telescopic bracket move closer to each other. Through the linkage mechanism, the first and second movable rods extend out of the fixed rod, thereby realizing the telescopic movement of the telescopic bracket. In this embodiment, the linkage mechanism can be implemented using a gear and rack structure that cooperates with the sliding member.

[0083] In this embodiment, as Figures 2a to 2cAs shown, the linkage mechanism includes a first rack 41, a first transmission gear 42, and a second rack 43. The first rack is connected to the sliding member 30; the first transmission gear 42 is rotatably mounted on the bracket and meshes with the first rack 41; the second rack 41 is mounted on the movable rod 20 and meshes with the first transmission gear 41, and extends along the direction of extension and retraction of the movable rod. In this embodiment, the first transmission gear 41 includes a first gear 421 and a second gear 422, which are coaxially connected. The first gear 421 is smaller than the second gear 422, and the first gear 421 meshes with the first rack 41, while the second gear 422 meshes with the second rack 43, thereby increasing the transmission ratio. Alternatively, the first gear 421 and the second gear 422 can also be meshed to drive the larger gear, thus increasing the transmission ratio. Figure 2a and 2b As shown, in this embodiment, a set of sliding parts are respectively provided on both sides of a lifting mechanism (such as a folding frame or a scissor frame) of the clothes drying machine. The two sets of sliding parts are respectively connected to the first movable rod and the second movable rod through two sets of linkage mechanisms.

[0084] Furthermore, the linkage mechanism can also be limited to the following two different structures:

[0085] First structure:

[0086] In the linkage mechanism, the first rack is fixedly connected to the sliding member, so the first rack moves synchronously with the sliding member under the drive of the sliding member 30. That is, when the sliding member slides along the first direction, it drives the first rack to slide in the first direction, thereby causing the first transmission gear to rotate and drive the second rack to slide in the second direction (opposite to the first direction), causing the corresponding movable rod to extend in the opposite direction to the sliding member; when the sliding member slides along the second direction, it drives the first rack to slide in the second direction, thereby causing the first transmission gear to rotate and drive the second rack to slide in the first direction (opposite to the second direction), causing the corresponding movable rod to retract in the opposite direction to the sliding member. In this embodiment, the first direction is the direction in which the movable rod moves away from the fixed rod along the length of the telescopic bracket, that is, the two sliding members on the same telescopic bracket move closer to each other; the second direction is the direction in which the movable rod moves closer to the fixed rod along the length of the telescopic bracket, that is, the two sliding members on the same telescopic bracket move away from each other.

[0087] The second structure:

[0088] In the linkage mechanism, the sliding member abuts against the linkage mechanism along the first direction, and the first rack of the linkage mechanism is located in the first direction of the sliding member. Therefore, during the movement of the sliding member along the first direction, the sliding member abuts against the first rack, thereby pushing the first rack to move along the first direction, which can drive the movable rod to extend through the linkage mechanism. When the sliding member moves along the second direction, the sliding member will disengage from the first rack. Therefore, during the movement of the sliding member along the second direction, there will be no transmission relationship with the linkage mechanism.

[0089] Based on the second type of linkage mechanism described above, an elastic element, such as a spring 60, is provided between the fixed rod 10 and the movable rod 20. The elastic element is used to continuously apply an elastic force to the movable rod in the direction of movement toward the fixed rod. A locking mechanism 100 is provided between the movable rod 20 and the fixed rod 10. The locking mechanism 100 can lock the movable rod. When the movable rod is in the locked state, it cannot extend or retract relative to the fixed rod. In this embodiment, the locking mechanism may include a locking pin 110 provided on the movable rod and a locking hole 120 provided at the corresponding position on the fixed rod. The movable rod 20 is sleeved inside the fixed rod 10. When the locking pin 110 extends out of the locking hole 120, the movable rod 20 is locked. When the locking pin 110 retracts into the locking hole 120, the movable rod is unlocked. During the movement of the slider along the first direction, the anti-reverse mechanism 100's anti-reverse pin 110 changes from being touched by the slider 30 (specifically pressed by the slider trigger part 31) to being disengaged from the slider, that is, changing from an unlocked state to a locked state; when the anti-reverse mechanism 100 is in the unlocked state, the slider 30 can drive the movable rod 20 to extend through the linkage mechanism until the anti-reverse mechanism changes to the locked state, such as... Figure 2b As shown. During the movement of the slider 30 in the second direction, the anti-reverse mechanism 100's anti-reverse pin 110 changes from being disengaged from the slider to being touched by the slider, that is, from a locked state to an unlocked state; when the anti-reverse mechanism changes to the unlocked state, the movable rod 20 undergoes a rapid retraction movement (rebound) under the action of the elastic element to retract into the fixed rod, as shown. Figure 2c As shown; when the moving part springs back, the second rack moves in the first direction, and the first rack moves in the second direction after being driven by the first transmission gear, so the second rack returns to the state of being engaged with the sliding frame.

[0090] In this embodiment, the first movable rod and the second movable rod at both ends of the fixed rod 10 can be located on the same straight line, or they can be arranged as follows: Figure 2bAs shown, the first movable rod and the second movable rod are staggered in the length direction, which can effectively save the length of the fixed rod. At this time, the fixed rod includes the first fixed rod and the second fixed rod side by side. The first movable rod and the second movable rod perform telescopic movements relative to the first fixed rod and the second fixed rod, respectively. Two sliding grooves are respectively provided on the opposite sides of the first fixed rod and the second fixed rod. Each set of sliding parts is embedded in the two sliding grooves on both sides so that they can slide in the sliding grooves.

[0091] In this embodiment, the lifting mechanism is connected to the telescopic bracket on which the drying rods are mounted. The lifting mechanism's movement drives the telescopic bracket's extension and retraction, thereby adjusting the spacing of the drying rods on the telescopic bracket. Based on this, this embodiment can control the spacing of the drying rods without requiring additional power equipment, achieving effective energy saving and consumption reduction.

[0092] In this embodiment, a weighing sensor and / or a current detection unit are also included; the weighing sensor and the current detection unit are respectively connected to the main controller in the clothes drying rack. The weighing sensor can be installed on the pulley assembly to detect the gravity borne by the sliding assembly, thereby determining the weight information of the drying rod. The weighing sensor can also be installed on the drying rod itself to check its weight. The current detection unit is connected to the motor to detect the motor's current. The main controller can determine the load-bearing capacity of the wire rope based on the motor's current, thereby determining the weight information of the drying rod. There is a correspondence table between the motor current and the weight borne by the drying rod; the main controller can determine the weight information on the drying rod based on this table and the detected motor current. In this embodiment, the clothes drying rack can detect the weight of the drying rod based on the weighing sensor and / or the current detection unit, thereby determining whether there are clothes drying on the rod. Based on this, the clothes drying rack can further control the extension and retraction of the support frame according to the drying status of the clothes on the rod, thereby adjusting the spacing between the drying rods.

[0093] In this embodiment, the clothes drying rack may include multiple horizontally parallel drying rods, such as two. When the clothes drying rack is not used for drying clothes, the two drying rods need to be stored on the outer periphery of the main unit or in the main unit's storage box, as close to the main unit as possible to improve the overall integrity of the main unit. This embodiment automatically adjusts the spacing between the drying rods based on the telescopic movement of the telescopic structural support. Specifically, when the drying rods are lowered, they can be moved to a first position, thereby increasing the spacing between the drying rods. When the drying rods are raised and need to be stored, they can be moved to a second position, thereby decreasing the spacing between the drying rods. This avoids the situation in the prior art where the spacing between the drying rods is too small due to the constraint of the main unit, causing clothes to collide with each other. This ensures the drying capacity and efficiency of the clothes drying rack while also maintaining the overall appearance of the clothes drying rack.

[0094] Example 2

[0095] This embodiment discloses a clothes drying rack, differing from Embodiment 1 only in that the support frame of this embodiment is equipped with a power device, and the telescopic movement of the support frame is driven by the power device. Specifically, the support frame includes a fixed rod and a first movable rod and a second movable rod disposed at both ends of the fixed rod; the ends of the first movable rod and the second movable rod away from the fixed rod serve as the telescopic ends of the support frame, used to connect the drying rod.

[0096] In this embodiment, as Figure 3 As shown, the power equipment mounted on the bracket includes a controller and a drive device. The controller is connected to the drive device, which includes a motor drive chip and a motor. The controller is connected to the motor via the motor drive chip. The output shaft of the motor is connected to a first movable rod and a second movable rod via a transmission mechanism, used to drive the first and second movable rods to extend and retract relative to the fixed rod. In this embodiment, the rotational motion of the motor output shaft is converted into linear motion through the transmission mechanism. Specifically, a gear can be mounted on the motor output shaft, and the first and second movable rods can be mounted on a rack. The gear on the motor output shaft meshes with the rack, or it meshes with the rack via a reduction gear, enabling the first and second movable rods to perform linear motion, i.e., to extend and retract relative to the fixed rod.

[0097] In this embodiment, the driving device on a bracket may include a motor, wherein the output shaft of the motor is connected to the movable rods through two sets of transmission mechanisms, thereby driving the two movable rods to move synchronously. Alternatively, the driving device on a bracket may also be equipped with two motors, each connected to the controller through a motor driver chip. The output shafts of the two motors are respectively connected to the first movable rod and the second movable rod through transmission mechanisms. Based on this, the controller can control the movable rod (the first movable rod or the second movable rod) at only one end of the bracket to perform telescopic movement, thereby realizing the change of position of the drying rod on only one side of the bracket, making the control more flexible and adaptable to different usage scenarios.

[0098] In this embodiment, the power equipment installed on the bracket may further include a controller, a first telescopic cylinder, and a second telescopic cylinder. The controller is connected to the first telescopic cylinder and the second telescopic cylinder via a solenoid valve or a relay. The first movable rod and the second movable rod are respectively installed on the first telescopic cylinder and the second telescopic cylinder. The controller controls the first movable rod and the second movable rod to extend and retract relative to the fixed rod through the first telescopic cylinder and the second telescopic cylinder.

[0099] In this embodiment, the aforementioned bracket can be a support connected to the lifting mechanism, or it can be another support frame directly connected to any position between multiple (e.g., two) drying rods, such as being located at the ends and / or middle positions of the drying rods. In this embodiment, each drying rod has its two ends connected to the telescopic ends of two brackets respectively, and more than two drying rods can be provided. Based on the controller in the power equipment, the first movable rods on the two brackets can be controlled to extend synchronously, and the second movable rods on the two brackets can also be controlled to extend synchronously. Therefore, the drying rods as a whole can extend in a relatively parallel manner, avoiding the situation where tilting would cause the movement to be unsmooth.

[0100] In this embodiment, the controller can communicate with the main controller on the clothes drying rack and / or an external terminal to receive extension / retraction commands sent by the main controller and / or the external terminal, thereby controlling the extension / retraction movement of the bracket via a drive device. Specifically, the controller can be connected to the main controller on the rack via a wireless communication module or via a wired connection. The controller can also be connected to external terminals such as user mobile phones or computers via a wireless communication module. In this embodiment, the main controller on the clothes drying rack can communicate with external terminals and / or a backend platform via wireless or wired connections. Based on this, operators can send extension / retraction commands to the bracket via an external terminal communicating with the controller, or via an external terminal or backend platform communicating with the main controller. In the latter case, after receiving the extension / retraction command, the main controller forwards it to the controller, which then controls the first and second movable rods to move relative to the fixed rod via a drive device according to the extension / retraction command.

[0101] Based on this, this embodiment can achieve telescopic movement through a drive device such as a motor or telescopic cylinder connected to the controller on the bracket. Since the drive device operates under the control of the controller, the corresponding drive commands can be flexibly adjusted based on the controller, making the control of the bracket's telescopic movement more flexible. In addition, since the controller can also communicate directly with an external terminal, or with an external terminal or backend platform through the main controller on the host, relevant operators can realize the telescopic control of the bracket based on the external terminal, backend platform, etc., thereby adjusting the spacing of the drying rods, effectively improving the controllability of the clothes drying rack's drying rod spacing, and also adapting to more personalized needs. For example, users can adjust the first position of the clothes drying rack's drying rods according to the actual installation environment requirements at home, avoiding the drying rods extending too far and affecting user activities, or extending too narrowly and affecting drying efficiency, etc.

[0102] Example 3

[0103] This embodiment discloses a working method of the clothes drying rack described in Embodiment 1 or Embodiment 2, including the following steps:

[0104] Step SA: Receive the clothes drying rack lowering control command, and control the clothes drying rack to lower according to the clothes drying rack lowering control command; after the clothes drying rack lowering movement is started, drive the bracket to extend, so that the clothes drying rack at the extension end of the bracket changes to the first position, at which time the clothes drying rack is in an extended state.

[0105] In step SA above in this embodiment, it is detected whether there are clothes drying on the drying rod or whether the drying rod is in a position below the drying position (including the drying position) when the descent movement of the drying rod is started;

[0106] If so, that is, if clothes are detected to be drying on the clothesline, or if the clothesline is below the drying position when the clothesline descent movement is started, then the support will not be driven to extend after the clothesline descent movement is started; at this time, it is determined that the clothes drying machine is in the drying state, and the clothesline is still in the first position, that is, the extended position, and there is no need to control the support to extend.

[0107] If no clothes are detected on the clothesline, and the clothesline is not below the drying position when the clothesline descent motion is started, then the support will extend after the clothesline descent motion is started. At this time, it is determined that the clothesline is not currently in the drying state. Therefore, the support will extend after the clothesline descent motion is started, so that the clothesline will change to the first position when or before it descends to the second preset position.

[0108] In this embodiment, the aforementioned second preset position can be set according to actual needs. For example, it can be the lower limit position of the drying rod, the clothes-collecting position of the drying rod, or a position set by the user according to their needs. This position is below the drying position. The aforementioned detection operation when the drying rod starts to descend can avoid frequent adjustments to the spacing of the drying rods, thus avoiding unnecessary adjustments to the spacing of the drying rods and effectively reducing the power consumption of the clothes drying machine.

[0109] In this embodiment, if it is the clothes drying rack shown in Embodiment 1, when the linkage mechanism is of the first type, after the clothes drying rod descent movement is started, the sliding parts on the lifting mechanism, such as the folding frame or the scissor frame, will move closer to each other. At this time, based on the linkage mechanism, during the descent movement of the clothes drying rod, the sliding parts will drive the first and second movable rods on the bracket to extend synchronously, thereby causing the clothes drying rod on the telescopic bracket to gradually change to the first position, that is, the unfolded position of the clothes drying rod. When the linkage mechanism is of the second type, during the descent movement of the clothes drying rod, the sliding parts will drive the first and second movable rods on the bracket to extend. During this process, the sliding parts will continuously touch the stop mechanism, keeping the stop mechanism in an unlocked state. When the sliding parts move to the corresponding position and the stop mechanism locks, the sliding parts will no longer be able to drive the first and second movable rods to move. At this time, the first and second movable rods stop moving, and the clothes drying rod is in the first position, that is, the unfolded position.

[0110] In this embodiment, if it is the clothes drying rack shown in Embodiment 2, that is, a power device is installed on the bracket, then in step SA above, when the main controller of the clothes drying rack receives the command to lower the drying rod, it can send a bracket extension movement command to the controller on the bracket while controlling the drying rod to lower. The controller on the bracket controls the first movable rod and the second movable rod to extend relative to the fixed rod based on the received extension movement command, so as to increase the distance between the drying rods on the first movable rod and the second movable rod. Further, when the main controller of the clothes drying rack receives the command to lower the drying rod, it first checks whether there are clothes drying on the drying rod, or checks whether the drying rod is below the drying position. If so, it is determined that the clothes drying rack is in the drying state, and the drying rod is currently still in the first position. Therefore, when controlling the drying rod to lower, it does not send an extension movement command to the controller on the bracket; if not, it is determined that the clothes drying rack is not in the drying state, and while controlling the drying rod to lower, it sends a bracket extension movement command to the controller on the bracket. The controller on the bracket controls the first movable rod and the second movable rod to extend relative to the fixed rod based on the received extension movement command, so as to increase the distance between the drying rods on the first movable rod and the second movable rod.

[0111] Step SB: Receive the clothes drying rack rod lifting control command, and control the clothes drying rack rod to lift according to the clothes drying rack rod lifting control command; after the clothes drying rack rod lifting motion is started, drive the bracket to retract, so that the clothes drying rack rod at the telescopic end of the bracket changes to the second position, at which time the clothes drying rack rods are in a retracted state.

[0112] In step SB of this embodiment, after the clothes drying rack starts its upward movement, it is first detected whether there are clothes drying on the clothes drying rack.

[0113] If so, the support frame will not be driven to retract, and the position of the drying rod will be acquired in real time. When the drying rod rises to the drying position, the drying rod will be controlled to stop rising. The above-mentioned drying position is the position where the drying rod stops when the clothes drying machine is drying clothes. It is usually a preset distance away from the upper limit position or the storage position of the drying rod. The upper limit position and the storage position of the drying rod are generally the highest positions that the drying rod can reach.

[0114] If not, the drive bracket will extend or retract, causing the drying rod to change to the second position when or before it rises to the first preset position. In this embodiment, the first preset position can be any position after the upper limit position, storage position, or drying position of the drying rod, and can be set according to actual needs.

[0115] In this embodiment, after the upward movement of the drying rod is initiated, if it is detected that there are no clothes drying on the drying rod, the support can be driven to extend and retract in any of the following ways:

[0116] The first method involves the drive bracket extending and retracting synchronously during the upward movement of the drying rod, which means controlling the drying rod to change position synchronously during the upward movement, so that the drying rod changes to the second position when or before it reaches the first preset position.

[0117] The second method involves acquiring the position of the drying rod in real time. After the drying rod moves to the drying position, the support is driven to extend and retract, so that the drying rod changes to the second position when or before it rises to the first preset position.

[0118] In this embodiment, if the clothes drying rack is the one shown in Embodiment 1, when the linkage mechanism is of the first type, after the clothes drying rod's upward movement is initiated, the sliding parts on the lifting mechanism, such as the folding frame or the scissor frame, will move away from each other. At this time, based on the linkage mechanism, during the upward movement of the clothes drying rod, the sliding parts will drive the first and second movable rods on the bracket to retract synchronously, thereby causing the clothes drying rod on the telescopic bracket to gradually change to the second position, that is, the retracted position of the clothes drying rod. When the linkage mechanism is of the second type, when the clothes drying rod reaches the drying position during its upward movement or before, the sliding parts cannot touch the stop mechanism. Therefore, the clothes drying rod is always in the first position, that is, the unfolded state. After the clothes drying rod reaches the drying position, the sliding parts touch the stop mechanism, causing the stop mechanism to unlock. The first and second movable rods of the telescopic bracket are retracted to the fixed rod under the action of the elastic element, causing the clothes drying rod to change to the second position, that is, the retracted position of the clothes drying rod.

[0119] In this embodiment, if it is the clothes drying machine shown in Embodiment 2, that is, a power device is set on the bracket, then in the above step SA, when the main controller of the clothes drying machine receives the instruction to raise the drying rod, it can send the bracket retraction movement instruction to the controller on the bracket while controlling the drying rod to rise. The controller on the bracket controls the first movable rod and the second movable rod to retract relative to the fixed rod based on the received retraction movement instruction, so as to reduce the distance between the drying rods on the first movable rod and the second movable rod. Furthermore, when the main controller of the clothes drying rack receives the command to raise the drying rod, it first checks whether there are clothes drying on the rod. If so, it controls the rod to rise while simultaneously acquiring the rod's position in real time. When the rod reaches the drying position, it stops rising. During this process, the main controller does not send a support retraction command, keeping the rod in its first unfolded position to maximize the spacing between the drying rods during drying. If not, the main controller can send a support retraction command to the controller while raising the rod, synchronizing the rising and retraction movements. This means that the spacing between the drying rods decreases synchronously during the rising process. Alternatively, if no clothes are detected on the rod, the main controller can send the support retraction command to the controller only after the rod has reached the drying position, causing the rod to retract only after reaching the drying position, thus reducing the spacing between the drying rods.

[0120] In this embodiment, the presence of clothing on the drying rod can be detected by the weight information detected by a weighing sensor installed on the clothes drying rack. This weighing sensor can be installed on the sliding assembly or on the drying rod itself. Alternatively, the weight borne by the drying rod can be determined based on the current of the motor in the clothes drying rack's power system, thus further confirming whether clothing is drying on the rod. In practice, there is a correspondence between motor current and the weight borne by the drying rod; therefore, the weight information on the drying rod can be determined based on this correspondence and the detected motor current.

[0121] In this embodiment, steps SA and SB are not sequential. Step SA is executed when the main controller on the clothes drying rack receives a control command to lower the clothes drying rod; step SB is executed when the main controller on the clothes drying rack receives a control command to raise the clothes drying rod. In addition, in this embodiment, the first preset position and the second preset position refer to the position of the clothes drying rod in the vertical direction, and the first position and the second position refer to the position of the clothes drying rod in the horizontal direction.

[0122] In summary, after the clothes drying rack's descent movement is initiated in this embodiment, the drive bracket extends, causing the drying rack at the extendable end of the bracket to move to the first position. After the clothes drying rack's ascent movement is initiated, the drive bracket retracts, causing the drying rack at the extendable end of the bracket to move to the second position. Compared to the second position, the spacing between the drying racks is larger in the first position. Based on this, the method of this embodiment can increase the spacing between the drying racks after the clothes drying rack descends, to accommodate drying distances and increase the amount of drying capacity; simultaneously, it can decrease the spacing between the drying racks after the clothes drying rack rises, to better fit the main unit's appearance, for example, by retracting them onto the main unit.
