This demand is no longer satisfied with the simple drying of clothes, but also focuses on the pursuit of intelligence and simplification. Some smart clothes drying racks have the function of automatically stopping or automatically lifting when encountering obstacles. Stopping or lifting when encountering obstacles means that during the descent process, the clothes drying rack immediately stops running or reverses when encountering obstacles to prevent accidental injuries. The existing implementation structure of stopping or lifting when encountering obstacles is to set a detector to directly detect whether the wire rope is loaded to determine whether the clothes drying rack is handling the obstruction state, and then the MCU controller controls the winding device to retract the wire rope. Among them, the detector used to detect whether the wire rope is loaded often rubs against the wire rope, which is easy to cause the wire rope to wear after a long period of friction, and there is a risk of causing the wire rope to wear and break.

[0028] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0031] With the improvement of the quality of life, consumers have an increasingly strong demand for smart clothes drying racks. This demand is no longer just satisfied with the simple drying of clothes, but also focuses on the pursuit of intelligence and simplification. Some smart clothes drying racks have the function of automatically stopping or automatically lifting when encountering obstacles. Stopping or lifting when encountering obstacles means that during the descent process, the clothes drying rack immediately stops running or reverses when encountering obstacles to prevent accidental injuries. The existing implementation structure of stopping or lifting when encountering obstacles is to set a detector to directly detect whether the wire rope is loaded to determine whether the clothes drying rack is handling the obstruction state, and then the MCU controller controls the winding device to retract the wire rope. Among them, the detector used to detect whether the wire rope is loaded often rubs against the wire rope, which is easy to cause the wire rope to wear after a long period of friction, and there is a risk of causing the wire rope to wear and break.

[0032] In order to overcome the above technical problems, the present embodiment provides a clothes drying machine with a weight feedback function, including a main unit, wherein the main unit includes a pulley 2 bracket, a pulley 2 and an axle 3, the axle 3 is installed on the pulley 2 bracket, and the pulley 2 is rotatably installed on the axle 3; the axle 3 is provided with a weighing sensor 4 for detecting the deformation amount of the axle 3.

[0033] Specifically, the clothes drying machine of this solution includes a drying rack in addition to the main machine. A traction machine 6 and a control panel are installed in the main machine. The steel wire rope of the traction machine 6 is guided by the pulley 2 and then hangs down to connect the drying rack. The control panel drives the drying rack to rise and fall by controlling the operation of the traction machine 6. The pulley 2 can be used to support and guide the steel wire rope that suspends the drying rack. The axle 3 is used to support the pulley 2, and the pulley 2 supports the steel wire rope. Therefore, the deformation of the axle 3 is proportional to the weight that the steel wire rope bears. In this solution, a weighing sensor 4 that can detect the deformation of the axle 3 is set on the axle 3. When used, the weighing sensor 4 is electrically connected to the control panel of the main machine, and the deformation of the axle 3 can be fed back to the control panel. The system can automatically convert the load-bearing weight of the steel wire rope to realize the function of controlling the drying rack to automatically stop or lift when encountering obstacles.

[0034] The principle of this solution to realize the function of controlling the drying rack to automatically stop or lift when encountering obstacles is: when there are no clothes or other items hanging on the drying rack, the weighing sensor 4 is in the initial state; when the drying rack encounters obstacles during the descent process, the pressure applied by the wire rope to the pulley 2 is reduced, so the pressure applied by the pulley 2 to the axle 3 is further reduced, and the deformation of the axle 3 is also reduced accordingly. At this time, the weighing sensor 4 arranged on the axle 3 will change from the tensile deformation state to the zero load state. After the weighing sensor 4 transmits the signal to the control board, the control board can automatically control the traction machine 6 to stop or reverse to lift the drying rack.

[0035] Based on the weighing sensor 4 of this solution, the clothes drying machine of this solution can also realize the function of automatically raising the lifting rod. Specifically, when the drying rack is in the lowered state, when the user needs to raise the drying rack, he only needs to lift one side of the drying rack slightly by hand, so that the weighing sensor 4 on the wheel axle 3 corresponding to the steel wire rope on this side changes from the tensile deformation state to the zero load state. After the weighing sensor 4 transmits the signal to the control board, the control board can automatically control the traction machine 6 to reverse and lift the drying rack. In this way, the user does not need to find a remote control to control the drying rack to rise after finishing drying, which greatly facilitates the operation and optimizes the user experience.

[0036] When clothes or other items are hung on the weighing sensor 4, the steel wire rope will further bend the axle 3 through the pulley 2. At this time, the weighing sensor 4 will be stretched and deformed by the further bent axle 3. The deformation of the weighing sensor 4 is proportional to the weight of the clothes or items hung on the drying rack. Therefore, the total weight of the drying rack and the objects hung on it can be detected in real time. Furthermore, this solution can also realize functions such as overweight reminder for drying, clothes drying reminder, and quick clothes collection.

[0037] The weighing sensor 4 of the present solution does not need to have any direct contact with the wire rope. During the lifting and lowering of the drying rack, the wire rope does not have any friction with other devices in the main unit except the rolling friction with the pulley 2. Therefore, the problem of wire rope wear and breakage can be effectively avoided. Therefore, compared with the traditional method of directly detecting the load of the wire rope, the present solution is safer.

[0038] Among them, the weighing sensor 4 includes a strain gauge, which is usually made of a thin sheet material, such as metal or plastic. The working principle of the strain gauge is based on the property that elastic materials will deform when subjected to force. The strain gauge is usually injected with conductive materials, such as gold or carbon, to form a resistor grid. When the strain gauge is subjected to force, the resistor grid will stretch or compress due to its deformation, thereby changing its resistance value. When a force is applied to the strain gauge, it will undergo a slight deformation, and this deformation will cause the resistance value inside the strain gauge to change. Normally, the resistance value of the strain gauge is proportional to the magnitude of the force. Therefore, by measuring the change in the resistance value of the strain gauge, the magnitude of the force applied to the strain gauge can be determined.

[0039] The weighing sensor 4 may be fixed on the axle 3 by, but is not limited to, adhesive fixing, welding fixing, screw fixing, rivet fixing, etc.

[0040] In one embodiment, the axle 3 is provided with a mounting groove 33 , and the weighing sensor 4 is disposed in the mounting groove 33 , so that the weighing sensor 4 avoids direct contact with the pulley 2 .

[0041] The weighing sensor 4 is fixedly mounted in the mounting groove 33 to ensure that it can accurately sense the deformation of the wheel shaft 3. Since there is no direct contact with the pulley 2, the weighing sensor 4 will not be subjected to friction or impact when the pulley 2 moves, thereby improving the stability and accuracy of the measurement.

[0042] In one embodiment, referring to Figure 6 The notch of the mounting groove 33 is located on the lower surface of the wheel axle 3 .

[0043] In normal use, the pulley 2 mainly applies downward pressure to the upper surface of the axle 3, but does not apply pressure to the lower surface of the axle 3. The notch of the mounting groove 33 is located on the lower surface of the axle 3, which will not damage the cylindrical surface of the upper surface of the axle 3, so that the upper surface of the axle 3 and the inner hole of the pulley 2 can be smoothly connected, avoiding affecting the stability of the operation of the pulley 2. In addition, the weighing sensor 4 can be installed on the top side of the mounting groove 33, which is exactly the side opposite to the compressed side of the axle 3. When the axle 3 is compressed and deformed, the deformation of the side opposite to the compressed side of the axle 3 is the most obvious. Therefore, the weighing sensor 4 set at this position can more accurately feedback the deformation of the axle 3, thereby improving the weighing accuracy.

[0044] In another embodiment, referring to Figure 7 The mounting groove 33 is a through groove that penetrates perpendicularly to the axial direction, and the notch of the mounting groove 33 is located on the side of the wheel axle 3.

[0045] Reference Figure 7 The structure of the mounting groove 33 can also facilitate the installation of the weighing sensor 4 to protect the weighing sensor 4.

[0046] In another embodiment, referring to Figure 8 The notch of the mounting groove 33 is located on the end surface of the wheel axle 3 .

[0047] In this structure, the weighing sensor 4 is installed into the mounting groove 33 from one end of the wheel shaft 3 and fixed, which can also achieve protection for the weighing sensor 4.

[0048] Preferably, in the above two embodiments, the weighing sensor 4 is installed on the top wall surface of the installation groove 33 .

[0049] The weighing sensor 4 is arranged on the top wall of the installation groove 33, which is the side opposite to the compressed side of the axle 3 and has the most obvious deformation. Therefore, the weighing sensor 4 arranged at this position can more accurately feedback the deformation of the axle 3, thereby improving the weighing accuracy.

[0050] In one embodiment, the wheel axle 3 includes a fixed portion 32 and a rotatable mounting portion 31 , the fixed portion 32 is connected to the pulley 2 bracket, and the rotational freedom of the fixed portion 32 relative to the pulley 2 bracket is locked, and the pulley 2 is rotatably mounted on the rotatable mounting portion 31 .

[0051] The fixing part 32 of the axle 3 is installed on the bracket of the pulley 2, and the rotational freedom of the entire axle 3 is locked by locking the fixing part 32, so that the axle 3 can be reliably installed, avoiding the problem that the pulley 2 rotates and drives the axle 3 to rotate, causing the weighing sensor 4 to be compressed.

[0052] Reference Figure 5 The rotating mounting part 31 is located in the middle of the wheel shaft 3, and the two ends of the rotating mounting part 31 are respectively connected to a fixing part 32. The pulley 2 bracket is provided with two opposite shaft holes 131, and the two fixing parts 32 are respectively inserted into the two shaft holes 131 to achieve simultaneous support of the two ends of the wheel shaft 3. One of the fixing parts 32 is provided with a rotation-stopping groove, which fits with the hole arm of the shaft hole 131 to limit the rotation of the wheel shaft 3.

[0053] In one embodiment, referring to Figure 5-6 The main machine also includes an anti-jumping frame 5, which includes two parallel side guard plates 51 and an anti-jumping plate 52 connected between the two side guard plates 51. The two side guard plates 51 are respectively located on both sides of the pulley 2 and connected to the wheel axle 3. The anti-jumping plate 52 blocks one side of the pulley 2 to prevent the wire rope from escaping from the wheel groove on the pulley 2.

[0054] The anti-jump wire rack 5 comprises two parallel side guard plates 51 and an anti-jump wire plate 52 connected between the two side guard plates 51. The two side guard plates 51 are respectively located on both sides of the pulley 2 and connected to the wheel axle 3 to form a stable support structure. The anti-jump wire plate 52 is shielded on one side of the pulley 2 to form a physical barrier to prevent the wire rope from escaping from the wheel groove during the movement of the pulley 2. This structure can effectively ensure the stability of the drying rack during the lifting process.

[0055] In one embodiment, the pulley 2 bracket includes two parallel support plates 13, the two ends of the wheel axle 3 are respectively fixed to the two support plates 13, the anti-jump wire frame 5 is installed between the two support plates 13, and the two side guard plates 51 are respectively provided with a wing plate 53 on the separated sides, and the support plate 13 is provided with a bayonet 132, and the wing plate 53 is clamped in the bayonet 132.

[0056] Reference Figure 4 , a bayonet 132 is simultaneously provided on the two support plates 13 at both ends of the wheel axle 3, and a wing plate 53 is correspondingly provided on the side of the side guard plate 51 of the anti-jump wire frame 5 facing the bayonet 132, and the wing plate 53 is engaged in the bayonet 132 to lock the rotational freedom of the anti-jump wire frame 5, so that the anti-jump wire plate 52 can be stably located on the top side of the pulley 2 to block the steel wire rope, thereby avoiding the problem of friction between the anti-jump wire plate 52 and the steel wire rope.

[0057] In one embodiment, the host comprises a host frame 1 , and the pulley 2 bracket is integrally formed on the host frame 1 .

[0058] Specifically, the mainframe 1 includes two parallel frame crossbeams 12 and two parallel frame longitudinal beams 11, and the two ends of the frame crossbeam 12 are respectively connected to the ends of the two frame longitudinal beams 11 to form a stable square frame structure. The pulley 2 bracket is integrally formed on the frame crossbeam 12, and a mounting opening 14 is provided in the middle of the frame crossbeam 12. The two support plates 13 of the pulley 2 bracket are respectively located at two opposite sides of the mounting opening 14, so that the pulley 2 can be installed at the mounting opening 14 to guide the wire rope from the inside of the mainframe 1 to the outside of the mainframe 1.

[0059] In this solution, the pulley 2 bracket and the frame crossbeam 12 of the main frame 1 are configured as an integrated structure, which has the advantages of fewer parts, low cost, and good structural connection reliability.

[0060] In one embodiment, the main machine includes a traction machine 6 and a control board, and the traction machine 6 and the weighing sensor 4 are electrically connected to the control board respectively.

[0061] Specifically, the traction machine 6 is arranged in the middle of the main machine, and two steel wire ropes are extended to the left and right sides of the main machine respectively. The two steel wire ropes are extended downward after turning the pulley 2 and connected to the drying rack. The operation of the traction machine 6 can be controlled by the control panel to realize the function of automatically controlling the lifting and lowering of the drying rack. The weighing sensor 4 is connected to the control panel, and can provide the control panel with real-time feedback of the weight and state of the drying rack. The control panel combines the signal fed back by the weighing sensor 4 and installs a preset program to automatically control the operation of the traction machine 6, so that the lifting and lowering of the lifting rod, the rebound when encountering resistance, the overweight reminder, the clothes drying reminder, the quick collection of clothes and other functions can be realized, realizing a smarter drying experience.
