Abstract
Description
Technical Field
[0001] This utility model relates to a clothes drying rack, and more particularly to a clothes drying rack clothes weight detection system. This weighing system can weigh the clothes on the drying rack and can provide early warning of unilateral overload on the drying rack. Background Technology
[0002] As people's living standards continue to improve, clothes drying racks, as an important piece of equipment in modern homes, are becoming increasingly diversified and intelligent in their functions. The weighing system, a key component of the clothes drying rack, provides users with numerous conveniences, such as helping them to rationally manage the weight of clothes for drying, avoiding damage to the drying rack due to overloading, and also improving drying efficiency and the quality of drying clothes to a certain extent.
[0003] Currently, the weighing systems of existing clothes drying racks mainly use the following methods:
[0004] Overall suspended weighing: This method involves suspending the entire clothes drying rack using sensors, which measure the total weight of the rack and the clothes being dried. Its advantages are relatively simple installation and low cost. However, its disadvantages are also obvious: it only obtains the total weight information and cannot determine the weight distribution of the clothes in different locations.
[0005] Pressure sensors are integrated into the support structure: Pressure sensors are mounted on the support legs or frame of the clothes dryer, and the total weight is calculated by measuring the pressure exerted on the support structure. This method can measure the overall weight relatively stably, but it cannot accurately measure the weight of specific areas on the drying rod.
[0006] Pallet weighing based on the principle of electronic scales: An electronic scale module is installed on the tray or basket of the clothes drying rack, and the clothes are placed on the tray for weighing. This method is more accurate for clothes placed on the tray, but for clothes hanging on the drying rod, it can only obtain the total weight data.
[0007] While existing clothes drying rack weighing systems meet users' needs for overall weight monitoring to some extent, a significant problem exists: they can only weigh the total weight on the drying rod, failing to accurately measure the weight of specific areas. This often leads to situations where the drying rod is overloaded in certain areas during actual use. For example, when drying clothes, users may hang a large number of heavy items on one side or in a few locations on the drying rod. Because the local weight cannot be known, when this local weight exceeds the drying rod's load-bearing capacity, it can easily cause deformation, damage, or even safety hazards, severely impacting the lifespan of the clothes drying rack and the user experience. Utility Model Content
[0008] The technical problem to be solved by this utility model is to provide a clothes load detection system on a clothes drying rack to prevent local overload.
[0009] The core technical concept of this utility model lies in pressing the roller shaft onto the upper side of the weighing strain gauge, or extending the roller shaft into the corresponding lower fixing block bearing hole, thereby connecting the roller shaft to the weighing strain gauge. The resistance change value of each weighing strain gauge is collected by the detection unit and processed by the controller to obtain the weight of the clothes drying, which is then displayed on the display terminal. At the same time, a warning is given for local overload to prevent the drying rod from being damaged due to local overload, thereby improving the service life of the clothes drying machine and the user experience.
[0010] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a clothes drying rack clothes weight detection system, used to weigh the clothes drying on the drying rack, including rollers located at both ends of the main unit, four weighing strain gauges and a display terminal;
[0011] Two steel wire ropes leading from the power unit pass over the rollers respectively;
[0012] A wheel axle passes through the roller and forms axle portions at both ends thereon;
[0013] The four shafts corresponding to the two rollers press respectively onto their respective weighing strain gauges;
[0014] The detection unit connected to the weighing strain gauge is connected to the controller via a signal line;
[0015] The display terminal is connected to the controller.
[0016] A further technical solution of this utility model is: the detection unit collects the resistance change value of each weighing strain gauge and performs comprehensive processing through the controller to obtain the weight of the clothes after drying, which is then displayed on the screen.
[0017] When one of the detection units collects a resistance change value exceeding a certain threshold, the controller determines that the clothes drying on the clothesline are partially overweight.
[0018] A further technical solution of this utility model is as follows: side plates are fixedly installed at both ends of the main unit, a fixing frame is provided on the inner side of the side plates, and a connection hole is provided on the weighing strain gauge;
[0019] The weighing strain gauge is mounted onto the mounting bracket by inserting a screw into the connection hole.
[0020] A further technical solution of this utility model is: a protective frame is provided on the inner side of the side plate, the protective frame includes a pair of parallel and spaced metal pieces, and the roller is located between the two metal pieces;
[0021] The metal sheet has a vertical waist-shaped hole, and the shaft extends into the vertical waist-shaped hole in a suspended manner;
[0022] A further technical solution of this utility model is: the display terminal is a display screen or a user's mobile phone installed on the surface of the host;
[0023] A further technical solution of this utility model is as follows: the weighing strain gauge is elongated, the connecting hole is located at the first end of the weighing strain gauge, and the shaft is pressed against the upper side of the second end of the weighing strain gauge.
[0024] Another technical solution adopted by this utility model to solve the above-mentioned technical problems is: a clothes drying rack clothes weight detection system, used to weigh the clothes drying on the drying rack, including rollers located at both ends of the main unit, four weighing strain gauges and a display terminal;
[0025] Two steel wire ropes leading from the power unit pass over the rollers respectively;
[0026] A wheel axle passes through the roller and forms axle portions at both ends thereon;
[0027] A fixing block is provided on the lower side of the weighing strain gauge;
[0028] The fixing block is provided with a load-bearing hole;
[0029] The four shafts corresponding to the two rollers extend into the load-bearing holes of the fixing blocks on the underside of their respective weighing strain gauges;
[0030] The detection unit connected to the weighing strain gauge is connected to the controller via a signal line;
[0031] The display terminal is connected to the controller.
[0032] A further technical solution of this utility model is: the inner side of the load-bearing hole has a spherical concave surface, and the outer end of the shaft is provided with a sphere, the sphere falling within the spherical concave surface.
[0033] A further technical solution of this utility model is: a reinforcing plate is provided on the top plate of the main unit, and the weighing strain gauge is suspended on the reinforcing plate by screws.
[0034] A further technical solution of this utility model is: a protective frame is provided on the inner side of the side plate, the protective frame includes a pair of parallel and spaced metal pieces, and the roller is located between the two metal pieces;
[0035] The metal sheet has a vertical waist-shaped hole, and the shaft extends into the vertical waist-shaped hole in a suspended manner.
[0036] Compared with existing technologies, the advantages of this invention are: This technical solution accurately detects the weight of clothes on a clothes drying rack, solving the technical problem that traditional clothes drying rack weighing systems cannot accurately measure localized weight. By establishing a direct force transmission relationship between the roller shafts at both ends of the clothes drying rack and the weighing strain gauges, the system can sense the weight changes on each side of the drying rod in real time. This localized detection capability allows users to clearly understand the distribution of clothes on the drying rod, avoiding damage to the drying rod due to localized overload. When the weight on one side exceeds a set threshold, the controller immediately issues a warning signal, reminding the user to adjust the distribution of clothes, thereby avoiding safety hazards caused by localized overload.
[0037] Specifically, the roller shaft is pressed against the upper side of the strain gauge, or the roller shaft is inserted into the load-bearing hole of the fixing block on the lower side of the corresponding strain gauge, thereby connecting the roller shaft to the strain gauge. Simultaneously, side plates are fixedly installed at both ends of the main unit of the clothes drying machine. The inner side of the side plates has a fixing frame and a protective frame. The strain gauge is installed onto the fixing frame with screws through the connecting holes. The roller is located between the metal plates of the protective frame, and the vertical oblong holes on the metal plates allow the shaft to extend suspended into them. This technique ensures that the strain gauge is stably fixed inside the side plates, and the protective frame protects the roller and shaft, improving the stability and reliability of the system.
[0038] Of course, the weighing system of the clothes drying rack can not only weigh the clothes being dried, but also measure the local overweight of the clothes on the drying rod. When the weight on one side of the drying rod exceeds the set threshold, the system can issue an early warning in time. Through weight measurement and overweight warning, users can arrange the drying of clothes reasonably, avoid problems caused by local overweight, make the clothes drying process safer and more convenient, and improve the service life of the clothes drying rack and the user experience.
[0039] The clothes drying rack uses a detection unit to collect the resistance change values of each weighing strain gauge, which are then processed by a controller to obtain the weight of the clothes to be dried. This data is then displayed on a terminal, allowing users to plan their laundry drying time and avoid problems caused by overloading. This technology not only improves weighing accuracy but also allows users to visually see the weight of the clothes, enhancing the convenience and intelligence of the clothes drying rack.

[0048] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0049] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.
[0050] Example 1:
[0051] like Figure 1 The diagram shown is a schematic representation of the overall structure of the clothes drying rack 100 in this embodiment. The weighing system on the clothes drying rack 100 includes rollers 20 located at both ends of the main unit, four weighing strain gauges 30, and a display terminal 40. Two steel wire ropes 50 extending from the power unit 51 pass over the rollers 20 respectively, and an axle passes through the rollers 20, forming shaft portions 21 at both ends. The weighing strain gauges 30 are elongated, and the four shaft portions 21 corresponding to the two rollers 20 press on their respective weighing strain gauges 30. The display terminal 40 is a display screen 40 mounted on the surface of the main unit or a user's mobile phone, and the display terminal 40 is connected to the controller 33.
[0052] It should be noted that the display terminal 40 can directly display the weight of the clothes being dried. This technology not only makes it easier for users to arrange the drying of clothes reasonably and avoid problems caused by overloading, but also allows users to see the weight of the clothes being dried intuitively, improving the convenience and intelligence of the clothes drying machine 100.
[0053] More preferably, the display terminal 40 can be a display screen 40 installed on the surface of the host or a user's mobile phone, providing users with multiple ways to view weight information. Users are not limited to being near the clothes drying rack 100; they can check the weight of the clothes being dried anytime, anywhere via their mobile phones, and arrange the drying time reasonably to avoid overloading. This technology allows users to guide other family members in using the clothes drying rack 100, and to reasonably arrange the drying weight and time, thus improving the user experience of the clothes drying rack 100.
[0054] like Figure 1 and Figure 2 As shown, the detection unit 31 connected to the weighing strain gauge 30 is connected to the controller 33 via the signal line 32. The detection unit 31 collects the resistance change value of each weighing strain gauge 30 and processes it through the controller 33 to obtain the weight of the clothes drying, which is displayed on the display screen 40. When the resistance change value collected by one of the detection units 31 exceeds a certain threshold, the controller 33 determines that the clothes drying on the drying rod 52 are locally overweight.
[0055] like Figure 3 The diagram illustrates the working principle of the weighing system of the clothes drying rack 100. More preferably, the weighing system of the clothes drying rack 100 can not only weigh the clothes being dried, but also measure localized overloading on the drying rod 52. When the weight on one side of the drying rod 52 exceeds a set threshold, even if the total weight does not exceed the rated value, localized overload may still cause structural damage or safety hazards. The system will issue a timely warning. Through weight measurement and overload warnings, users can rationally arrange the drying of clothes, avoiding problems caused by localized overloading, making the clothes drying process safer and more convenient, and improving the service life of the clothes drying rack 100 and the user experience.
[0056] like Figure 4 As shown, side plates 53 are fixedly installed at both ends of the main unit. A fixing frame 54 is provided on the inner side of the side plate 53. A connecting hole 34 is provided on the weighing strain gauge 30. Screws 35 are inserted into the connecting hole 34 to install the weighing strain gauge 30 onto the fixing frame 54. A protective frame is provided on the inner side of the side plate 53. The protective frame includes a pair of parallel and spaced metal plates 55. A roller 20 is located between the two metal plates 55. The connecting hole 34 is provided at the first end of the weighing strain gauge 30. The shaft 21 is pressed against the upper side of the second end of the weighing strain gauge 30.
[0057] More preferably, the metal sheet 55 has a vertical oblong hole 56, and the shaft 21 extends into the vertical oblong hole 56 in a suspended manner. The roller 20 is located between the metal sheets 55 of the protective frame. This technique allows the weighing strain gauge 30 to be stably fixed inside the side plate 53. The vertical oblong hole 56 allows the shaft to move within a certain range, which can accommodate small displacements under different weights. The protective frame protects the roller 20 and the shaft 21, preventing external factors from interfering with the weighing system and improving the stability and reliability of the clothes rack 100.
[0058] This utility model's clothes drying rack weight detection system represents a significant breakthrough in detection technology. Through high-precision weight detection and a local overload warning function, it provides users with an intelligent clothes drying experience. The system utilizes rollers 20 and weighing strain gauges 30 located at both ends of the main unit to accurately sense local and overall weight changes of the clothes on the drying rod. When the weight on one side exceeds a set threshold, the controller 33 immediately issues a warning, effectively preventing damage to the drying rod or safety hazards caused by local overload.
[0059] Example 2:
[0060] like Figure 6 and Figure 7 As shown, the overall structure of this embodiment is the same as that of Embodiment 1. The difference is that a fixing block 57 is provided on the lower side of the weighing strain gauge 30, and a load-bearing hole 58 is provided in the fixing block 57. The four shafts 21 corresponding to the two rollers 20 extend into the load-bearing holes 58 of the fixing block on the lower side of their respective weighing strain gauges 30. This technical means further optimizes the connection between the roller shafts 21 and the weighing strain gauge 30, making the weight transmission more direct and stable.
[0061] Preferably, a reinforcing plate 59 is provided on the top plate of the main unit, and the weighing strain gauge 30 is suspended to the reinforcing plate 59 by screws 35. The reinforcing plate 59 provides better support and protection for the weighing strain gauge 30, improving the durability and service life of the clothes drying rack 100. At the same time, the inner side of the load-bearing hole 58 has a spherical concave surface, and the outer end of the shaft 21 is provided with a ball 22. The ball 22 falls in the spherical concave surface, and the shaft 21 contacts the fixing block 57 with a spherical structure, thereby avoiding measurement errors caused by installation errors or changes in the point of application of external force, ensuring that the center point of the ball is pressed down every time force is applied. This technical means not only improves the weighing accuracy, but also enhances the stability and reliability of the system.
[0062] Example 2 significantly optimizes the design of the clothes hanging weight detection system for clothes drying racks. By setting a fixed block 57 with a spherical concave surface on the lower side of the weighing strain gauge 30 and having the ball of the roller shaft 21 cooperate with it, a more direct, stable and accurate weight transfer is achieved.
