Description

Technical Field

[0001] This application relates to the field of clothes drying control technology, specifically to clothes drying machines and their operation control systems. Background Technology

[0002] Smart clothes drying racks are gaining popularity due to their ability to automatically raise and lower, and the integration of functions such as lighting, drying, and sterilization. They have become an indispensable part of smart home products.

[0003] To precisely control the position of the clothes drying rack's rod and ensure its safe and reliable operation, limit switches, including upper and lower limit switches, are typically installed at the end of the main unit. When the clothes drying rod reaches the preset maximum safe position, the limit switch is triggered, cutting off the motor power and stopping the machine from rising. Without an upper limit switch, the motor might continue running even when the rod reaches its highest position, attempting to pull the already-reached rod upwards. This could lead to severe motor overload and burnout, or damage to the steel cable, the rod hitting the top, damage to the pulleys, or even deformation and damage to the entire machine structure. Limit switches are essentially the first line of defense against mechanical damage.

[0004] Currently, limit switches for clothes drying racks are generally installed on the main unit's casing, and most of these features need to be exposed on the main unit. Specifically, the limit switch and trigger arm need to be exposed on the side wall of the main unit. This requires openings in the casing, which compromises the integrity of the casing, especially the concealed design required for recessed clothes drying racks. Furthermore, current clothes drying racks generally rely solely on the on / off state of the limit switch to determine whether the drying rod has reached its limit, which cannot guarantee reliability.

[0024] The wireless signal transmitting unit and the wireless signal receiving unit are positioned opposite each other and are respectively located on both sides of the displacement path of the steering component.

[0025] Preferably, when the clothes drying rack power system includes a motor and a motor driver, the control unit is connected to the motor through the motor driver; the position detection unit is a Hall sensor installed on the motor for detecting the rotation of the motor;

[0032] This utility model has the following advantages and effects compared with the prior art:

[0033] (1) The clothes drying rack operation control system of this utility model includes a control unit and a triggering unit and a position detection unit respectively connected to the control unit; wherein the position detection unit can detect the real-time position information of the drying rod, and the triggering unit can detect the displacement of the steering component due to gravity. Based on this, the control system of this utility model can control the operation of the drying rod according to the current position information of the drying rod and the force on the steering component, so that the drying rod is in the drying position when clothes are being dried, and can be stopped in time when it rises to the upper limit position. It considers the position of the drying rod and the changes in the load of the drying rod, which effectively improves the reliability of the limit trigger of the clothes drying rack. The dual-factor collaborative judgment method can effectively avoid accidents such as the drying rod hitting the top due to the failure of a single signal. In addition, in the control system of this utility model, the triggering unit can be set in a position inside the main unit that can be triggered by the steering component, so it does not need to be exposed outside the main unit of the clothes drying rack, thus ensuring the integrity of the main unit of the clothes drying rack.

[0034] (2) The clothes drying rack operation control system of this utility model may also include a current detection unit. The control unit is connected to the output terminal of the power system of the clothes drying rack, such as the motor, through the current detection unit to obtain the current output by the power system of the clothes drying rack. Based on this, when the control unit detects that the distance between the clothes drying rack and the upper limit position is less than the preset distance according to the real-time position information of the clothes drying rack, and detects that the current output by the power system exceeds the preset current threshold without receiving a trigger signal, it can directly control the clothes drying rack to stop running. Therefore, it can avoid the situation where the clothes drying rack hits the top due to the inability to determine that the clothes drying rack has reached the upper limit position caused by the failure of the trigger unit, and provides a higher level of protection for the safe operation of the clothes drying rack.

[0035] (3) In the clothes drying rack operation control system of this utility model, the rotating components sensed by the triggering unit include a pulley and an elastic element; wherein the pulley is connected to the main unit through the elastic element, and when the force on the traction rope exceeds the preset value, the pulley can be displaced to the corresponding position to trigger the triggering unit. Based on this, the control system of this utility model does not need to make significant modifications to the original structure of the clothes drying rack in order to achieve control of the operation of the clothes drying rack. It only needs to set the pulley to be displaceable and move the position of the existing triggering unit, such as the obstruction switch, from the limit position to a position that can be triggered by the displaced pulley, which effectively reduces the mechanical modification cost of the clothes drying rack.

[0039] 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.

[0040] Example 1

[0041] Currently, limit switches on clothes drying racks are generally installed on the main unit's casing, and most of these features need to be exposed on the main unit. Specifically, the limit switch and trigger arm need to be exposed on the side wall of the main unit. This requires openings in the casing, which compromises the integrity of the casing, especially the concealed design required for recessed clothes drying racks. Furthermore, current clothes drying racks generally rely solely on the on / off state of the limit switch to determine whether the drying rod has reached its limit, meaning they depend on a single signal, which cannot guarantee reliability.

[0042] Based on the problems existing in the prior art, this embodiment provides a clothes drying rack operation control system, which enables reliable and safe control of the clothes drying rack rod.

[0043] The clothes drying rack referred to in this embodiment generally includes a main unit and drying rods. The main unit is generally installed on the ceiling. The aforementioned drying rods generally refer to drying rod assemblies, which are set below the main unit by a traction rope (such as a steel wire rope) or other lifting components. The drying rod assembly generally includes 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.). Clothes of general size are usually hung on the clothes drying rods, quilt drying rods, or small drying rods using clothing hangers (such as clothes hangers). The main unit contains a main control module, a power system, and other components. The power system of the clothes drying rack can include a motor, a reel, a steering assembly, and cables (such as steel wire rope). The main control module 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 steering assembly to change direction (from horizontal to vertical) before being fixedly connected to the drying rod assembly below the main unit. The reel rotates under the motor's power, winding and unwinding the steel wire rope, thereby causing the drying rod assembly on the steel wire rope to rise or fall. Additionally, the clothes drying rack may be equipped with lighting, drying, and disinfection modules, which can be controlled by commands issued from the main control module on the main unit.

[0044] The clothes drying rack operation control system in this embodiment includes a control unit, a triggering unit, and a position detection unit. Wherein:

[0045] The position detection unit is connected to the control unit and is used to detect the real-time position information of the clothes drying rack's drying rod. In this embodiment, when the clothes drying rack's power system includes a motor and a motor driver, the control unit is connected to the motor through the motor driver. The position detection unit can be a Hall sensor installed on the motor to detect its rotation. The Hall sensor calculates the motor speed based on the number of rotations per unit time, thereby calculating the position of the drying rod pulled by the traction rope. Alternatively, the position detection unit can also be a distance sensor installed on the main unit or the drying rod, including ultrasonic sensors, infrared distance sensors, laser sensors, etc. In this embodiment, the position information of the drying rod is determined by measuring the distance between the drying rod and the main unit.

[0046] In this embodiment, the triggering unit is located on the main body of the clothes drying rack, for example, in or beside the displacement path of the steering component of the clothes drying rack's traction rope. When the steering component moves to the corresponding position, the triggering unit can be triggered. Since the steering component of the traction rope is installed on both sides inside the main body, the triggering unit located on the displacement path of the steering component is also inside the main body of the clothes drying rack. In this embodiment, the steering component will displace when the force it experiences is greater than or equal to a threshold. When the steering component moves to a position that can trigger the triggering unit, the triggering unit will be triggered, thus issuing a trigger signal. The control unit connected to the triggering unit (e.g., the main control module of the clothes drying rack) will receive the trigger signal. The threshold can be 10KG, and the force on the steering component includes the weight of the drying rod itself and the weight of the clothes and other items hanging on the drying rod. When the clothes drying rack is unloaded, meaning no other items are hanging on it, the force on the steering component will not exceed the threshold before the rack reaches its upper limit, so the trigger unit will not be activated. When clothes or other items are hung on the rack, causing the force on the steering component to be greater than or equal to the threshold, the trigger unit will be activated. When the rack reaches its upper limit or encounters an obstacle above it during its ascent, the rack will be obstructed, and the force on the steering component will be greater than or equal to the threshold, at which point the trigger unit will be activated.

[0047] like Figure 2 As shown, the steering assembly in this embodiment includes a pulley component 1 and an elastic component 2. The pulley component is displaceably mounted on the main body of the clothes drying machine and is used to provide steering for the traction rope output by the power system of the clothes drying machine, so that the traction rope after steering can be connected to the drying rod below the main body of the clothes drying machine. One end of the elastic component is connected to the main body, and the other end is connected to the pulley component, which is used to limit the displacement path of the pulley component. The triggering unit is disposed on the main body of the clothes drying machine and can be triggered by the pulley component that has been displaced to the corresponding position. The pulley component includes a housing (not shown in the figure), a pulley, and an axle. The pulley is disposed in the housing through the axle, and the housing can limit the position of the traction rope on the pulley, that is, prevent the traction rope from falling off the pulley. The elastic component is connected to the end of the axle of the pulley component; the triggering unit is disposed in the displacement path of the axle of the pulley component or on both sides of the displacement path. Specifically:

[0048] The pulley in the pulley assembly is used to guide the traction rope, such as the steel wire rope 3, that connects to the clothes drying rack on the clothes drying rack. The pulley assembly is mounted displaceably on the main body of the clothes drying rack. For each pulley assembly, two grooves can be set at the corresponding position on the main body. The two ends of the axle 4 passing through the pulley on the pulley assembly are respectively set on the two grooves. Based on this, the pulley assembly can slide relative to the main body, i.e., generate displacement. The sliding of the pulley assembly can be vertical, tilted downward, or horizontal, etc. In this embodiment, it is only necessary to ensure that the pulley assembly can be displaced to the corresponding position of the trigger unit 5 after the force exceeds the threshold. Considering the current structure of the clothes drying rack, at least one steering component can be set at each end of the main body of the clothes drying rack. In the clothes drying rack of this embodiment, one end of the traction rope, such as the steel wire rope, is wound around the winding wheel of the power system, and the other end extends downward after passing around the pulley to connect with the clothes drying rack. Therefore, the pulley assembly bears the weight of the clothes drying rack.

[0049] The elastic element in the steering assembly is connected to the main unit at one end and to the pulley assembly at the other end, specifically to the axle on the pulley assembly; for example... Figure 2 As shown, for each pulley component, two elastic elements can be configured on the left and right sides respectively. One end of each elastic element is connected to both ends of the pulley component's axle, and the other end of each elastic element is fixedly connected to the main unit. The elastic elements can be tension springs. When the force on the pulley component does not exceed a preset threshold, the tension spring is in a reset state. At this time, the pulley component is in position a (such as the highest position) under the tension of the tension spring. When the force on the pulley component is greater than or equal to the preset threshold, that is, when the load on the drying rod exceeds a certain value, the pulley component will be displaced, thereby driving the tension spring to stretch in its displacement direction. If the load on the drying rod disappears or decreases so that the force on the pulley component does not exceed the preset threshold, the pulley component will return to position a under the tension of the tension spring.

[0050] In this embodiment, when triggered by the pulley assembly, a trigger signal, such as a high-level signal, a low-level signal, or a corresponding pulse signal, will be generated and sent to the control unit. After receiving the trigger signal, the control unit can determine that the triggering unit has been triggered by the pulley assembly. The triggering unit can be a contact switch unit or a non-contact switch unit.

[0051] When the unit is a contact-type switch, a micro switch can be selected; the trigger piece of the micro switch is located in the displacement path of the steering assembly, and the micro switch is triggered when the steering assembly moves to the corresponding position and contacts it.

[0052] For non-contact switching units, photoelectric sensors, such as infrared sensors, laser sensors, and ultrasonic sensors, can be used. The non-contact unit includes a wireless signal transmitting unit and a wireless signal receiving unit. The wireless signal transmitting unit sends wireless signals. The wireless signal receiving unit is connected to the control unit and receives the wireless signals sent by the transmitting unit. If no wireless signal is received, it sends a trigger signal to the control unit. The transmitting and receiving units are positioned opposite each other on either side of the steering component's displacement path. When the steering component moves to a position between the transmitting and receiving units, the signal emitted by the transmitting unit will be reflected by the steering component, thus preventing the receiving unit from receiving the wireless signal. The wireless signal can be an infrared signal, laser signal, ultrasonic signal, etc.

[0053] In this embodiment, when the triggering unit is a contact switch unit, if the triggering unit is triggered by the axle of the pulley component, then two triggering units can be set for each steering component. The two triggering units are located on the path that the displacement at both ends of the axle will take. Both triggering units are connected to the control unit. When the control unit receives a trigger signal from one of the triggering units, or when it receives trigger signals from both triggering units simultaneously, it determines the stored triggering condition to further control the operation of the drying rack based on the drying rack position information.

[0054] In this embodiment, the control unit is connected to the clothes drying rack's power system. Based on the real-time position information of the drying rod and the trigger signal received by the trigger unit, the control unit controls the operating state of the drying rod through the power system. The specific control principle is as follows:

[0055] First, the positions of the drying rack are divided into a first preset position, a second preset position, and an upper limit position from bottom to top. The first preset position can be the drying rack position, or it can be 8 to 15 cm below the upper limit position, for example, 10 cm below the upper limit position. The second preset position can be 1 to 2 cm below the upper limit position, for example, 1 cm below the upper limit position.

[0056] When the control unit receives a command to raise the drying rack, it controls the rack to begin rising, and controls the rack based on the following conditions:

[0057] When the position detection unit determines that the drying rod is currently below the first preset position, that is, below the drying rack position, it determines whether the trigger unit has been triggered. If it has been triggered, the drying rod is controlled to rise and stop at the first preset position. At this time, the trigger unit is triggered, possibly because there are clothes with a certain weight on the drying rod, so the drying rod is controlled to stop at the drying rack for drying. If it has not been triggered, the drying rod is directly controlled to continue rising.

[0058] When the position information detected by the position detection unit determines that the drying rod is currently between the first preset position and the second preset position, it is determined whether the triggering unit is triggered. If it is triggered, the drying rod is controlled to fall back to the first preset position. At this time, the triggering unit is triggered, possibly because although there are clothes hanging on the drying rod, the weight of the clothes is not enough to cause the steering component to move to the position where the triggering unit can be triggered. After the drying rod moves beyond the first preset position, due to the obstruction of the clothes hanger or other objects on the drying rod, the drying rod is subjected to resistance, causing the steering component to be displaced to the position where the triggering unit can be triggered. Based on this, this embodiment controls the drying rod to fall back to the first preset position, which is the drying rack position.

[0059] When the position detection unit determines that the clothes drying rod is currently between the second preset position and the upper limit position, it checks whether the trigger unit has been triggered. If so, it determines that the drying rod is at the upper limit position and controls the drying rod to stop running. If not, it obtains the output current of the clothes drying machine's power system, such as the motor current, and determines whether it exceeds the preset current threshold. If so, it assumes that the drying rod has hit the top and controls the drying rod to stop running.

[0060] The aforementioned preset current threshold can be set to 1.2I_nom, where I_nom is the average current of the motor when the clothes drying rack rod rises normally without any load or obstruction. Under normal circumstances, if the trigger unit does not malfunction, when the drying rack rod moves from the second preset position to the upper limit position, the obstruction from the main unit or the ceiling will definitely exert a force exceeding the threshold on the pulley assembly, thus triggering the trigger unit. Considering the possibility of trigger unit malfunction, in the absence of a trigger signal, the control unit can further consider the output current value of the power system and determine whether the drying rack rod has reached the top based on this output current. When the output current information of the power system exceeds the preset current threshold, the drying rack rod is immediately stopped. Therefore, this embodiment provides a higher level of protection for the safe operation of the drying rack rod through the output current of the power system, avoiding the situation where the drying rack rod hits the top due to the inability to determine whether it has reached the upper limit position caused by a trigger unit malfunction.

[0061] In this embodiment, the control unit can be the controller originally installed on the main control module of the clothes drying machine host, or it can be a separately installed controller. If it is the latter, the controller needs to be connected to the main control module on the host so that the main control module controls the operating status of the clothes drying machine based on the trigger signal or clothes drying machine control signal sent by the control unit.

[0062] In summary, the clothes drying rack operation control system of this embodiment can control the operation of the drying rod based on its current position information and the force on the steering component. This ensures that the drying rod is in the drying position when clothes are being dried, and can be stopped promptly when it reaches its upper limit. It considers both the position of the drying rod and changes in load, effectively improving the reliability of the limit triggering. The dual-factor collaborative judgment method effectively avoids accidents such as the drying rod hitting the top due to a single signal failure. Furthermore, in this embodiment, the triggering unit only needs to be located within the main unit and triggered by the steering component; therefore, it does not need to be exposed outside the main unit housing, ensuring the integrity of the main unit housing.

[0063] Example 2

[0064] This embodiment discloses a clothes drying rack, including a main unit and a drying rod. The drying rod is set below the main unit by a traction rope. The main unit is equipped with a power system and a steering component. One end of the traction rope is connected to the power system, and the other end passes through the steering component and is connected to the drying rod after turning. The control system of this embodiment also includes the clothes drying rack operation control system described in Embodiment 1.

[0065] In this embodiment, the steering component is displaceable (i.e., movable) within the main unit, and can trigger the trigger unit in the clothes drying rack's operation control system when it is displaced to the corresponding position. In this embodiment, the structure of the steering component can be as shown in Embodiment 1, including a pulley component 1 and an elastic component 2, wherein the pulley component includes a housing (…). Figure 2 (Not shown in the figure), pulley and axle. The pulley is set in the housing through the axle. The housing restricts the position of the traction rope on the pulley to prevent the traction rope from coming off the pulley. The specific structure of the pulley frame and elastic element can be as shown in Example 1, and will not be described again here.

[0066] like Figure 3As shown, a support frame 11 is provided at the end of the main unit. The support frame 11 is provided with a mounting port 12 for installing the steering component and a mounting component for installing the trigger unit. The mounting port can be located approximately in the middle of the support frame. Mounting plates 13 are provided on both opposite sides of the mounting port 12. Mounting holes 14 are provided on the mounting plates 13 (corresponding to the sliding grooves provided on the main unit in Embodiment 1). When the steering component is located at the mounting port, it passes through the pulley and the two ends of the wheel axle on the housing, which are respectively located in the mounting holes 14 of the mounting plates 13 on both sides of the mounting port 12, and can move within the mounting holes. In this embodiment, the mounting holes can be set as strip holes. After the clothes drying machine main unit is installed, the length direction of the mounting holes on the mounting plate is the vertical direction perpendicular to the ground. Based on this, the steering component can move up and down through the mounting holes. When the force on the steering component does not exceed the reset force of the elastic element, the elastic element is in the reset state and is not stretched. Therefore, the steering component is in its original position and will not trigger the trigger unit. When the force on the steering component exceeds the tensile strength of the elastic element, the elastic element begins to stretch. The greater the force on the steering component, the longer the elastic element will stretch. When the force exceeds a certain value, it can physically touch the trigger unit or move between the wireless transmitter and receiver units of the trigger unit, blocking both of them, thereby causing the trigger unit to send a trigger signal to the control unit.

[0067] In this embodiment, the mounting component for installing the trigger unit on the support frame can be set on one or both sides of the mounting port. The specific location is not limited, as long as the trigger unit can be triggered by the steering component.

[0068] The above description is only an optional implementation method for some implementation scenarios of this application. It should be noted that for those skilled in the art, other similar implementation methods based on the technical concept of this application without departing from the technical concept of this application also fall within the protection scope of the embodiments of this application.
