Description

TECHNICAL FIELD

[0001] The present application is an intelligent clothes drying rack, in particular, a multifunctional and intelligent clothes drying rack which can provide convenience for people to dry clothes from two aspects of accelerating drying speed and convenient drying process. BACKGROUND

[0002] The traditional drying method is simple suspension and air drying, the drying process is inconvenient, and the drying time is long. In the drying process, due to the different angles of sunlight, the clothes cannot be fully irradiated by sunlight. In some families with limited balcony space, if people dry clothes outdoors, due to the uncertainty of weather changes, when unexpected situations such as rainy days occur, people cannot collect the clothes for drying in time, which will cause the clothes to be wet, and people have to dry the clothes again. The main intelligent drying method on the market is mainly suspension type, which combines sensors, Internet technology, etc. to realize automatic up and down, drying and other functions, but the function is relatively single. The clothes drying rack can be folded and unfolded, but it cannot automatically seek light. The clothes drying rack can automatically seek light, but it cannot automatically avoid rain. In short, the integration degree of the function is low, which cannot meet the requirement of people for the convenience of life. SUMMARY

[0003] The purpose of the present application is to solve the above problems, and to provide an intelligent clothes drying rack which can provide more convenience and faster drying for people to dry clothes from two aspects of accelerating drying speed and convenient drying process, and to have more functions and higher automation and intelligence, so as to solve the shortcomings of the prior art.

[0004] The intelligent clothes drying rack provided by the present application has a lead screw, an optical axis, a moving support, a lower disc and a track, wherein the lead screw and the optical axis are installed on the ceiling or the support in the room, the moving support is installed on the lead screw and the optical axis through a nut block and a sliding block to move, the lead screw is driven by a motor; the moving support is provided with a ratchet winding mechanism, a steel wire of the ratchet winding mechanism is used to lift and lower the lower disc, a six-link mechanism is connected between the moving support and the lower disc to ensure stable lifting and lowering; the lower disc is provided with a track, the track is driven by a motor to rotate around the lower disc, and the track is provided with a clothes hook; the moving support is provided with a light intensity sensor and a raindrop sensor; the lead screw motor, the track motor, the winding motor and the sensors are electrically connected with a controller.

[0005] A limit sensor is further installed on the moving support and connected with the controller to ensure that the lower disc is lifted and lowered within a normal range.

[0006] The clothes hook on the track is a cam clothes buckle, which has a hook body and a torsion arm, the torsion arm is installed on the hook body through a torsion spring to keep the torsion arm and the hook body in a normally closed state, and the upper end of the torsion arm is provided with a push head.

[0007] The track is provided with a block rudder, the block rudder shaft is provided with a block, and the block is used to block the torsion arm of the cam clothes buckle moving on the track to make the clothes automatically fall into the clothes collecting position when clothes are collected.

[0008] The lower disc is a rectangular disc, and the track is installed on the pulley at the four corners of the lower disc to rotate, and the pulley is driven by the track motor.

[0009] The track is a synchronous belt.

[0010] The ratchet winding mechanism has a ratchet housing and a ratchet wheel installed in the ratchet housing and connected to the ratchet wheel, and the ratchet wheel is kept in a constant state by the ratchet teeth. The ratchet teeth are a symmetrical ratchet pair rotating on the same axis, and the ratchet pair is provided with a ratchet cam in the middle. The ratchet cam is driven by the rudder to push away the left or right ratchet to make the ratchet wheel rotate intermittently in one direction, and then the ratchet is pushed back by the reset spring. The ratchet wheel is connected to the winding motor through the shaft to drive the winding motor. The cam motor is also controlled by the controller, and the steel wire is wound on the ratchet wheel.

[0011] The cam motor and the winding motor are respectively installed on the two sides of the ratchet housing.

[0012] The controller is a programmable single-chip microcomputer.

[0013] The whisk sensor is arranged on the ceiling or support corresponding to the optical axis away from the balcony side, and is set as the reference origin.

[0014] The present application is used and works as follows:

[0015] When drying clothes, hang a piece of clothes on a single clothes hanger and hang it into the cam clothes buckle in front, start the track switch, let the track rotate a certain distance to hang the next piece of clothes into the next cam clothes buckle, and operate in this way until the clothes are hung or the track is full of clothes. Stop the track rotation, start the ratchet winding mechanism, the steel wire lifts the lower disc, the six-link mechanism retracts, and the lower disc remains stable. Stop when the lower disc reaches the predetermined height.

[0016] The light intensity sensor outputs a light intensity value signal to the controller according to the change of external light intensity, and the controller controls the rotation of the lead screw motor. The moving support moves accordingly, so that the clothes receive the strongest light. With the whisk sensor as the origin, when the raindrop sensor, light intensity sensor and whisk sensor are not triggered, the clothes hanger moves to the origin and stops when it touches the whisk sensor. When the raindrop sensor detects rain outside, the lead screw motor rotates to stop when the clothes hanger touches the whisk sensor. When there is no rain and the light intensity sensor detects a value greater than the set value, the motor stops rotating.

[0017] If the clothes are hung on the track, the controller will keep the track rotating slowly when adjusting the lower disc to the best light receiving position, so that the clothes can be evenly lighted. When there is only one side of clothes hung on the track, the controller will rotate the track to the side with the strongest light, so that the clothes can be dried quickly.

[0018] After the clothes are dried, the B button sensor is turned off, the lower disc is lowered to the limit position, the C button sensor is turned on, the block rudder takes the block to the predetermined angle, and the track motor is started. The cam clothes buckle is gradually opened at the block, and the single clothes rack is automatically dropped to the clothes collecting place and folded by manual operation. After the clothes on the track are collected, the block rudder is turned back to the original angle, the block is lifted, the winch motor is rotated to lift the lower disc to the predetermined height, and the lead screw motor is rotated to drive the moving support to return to the original position for next use.

[0019] The clothes drying device has various functions, convenient operation, certain interactivity, and can provide people with more convenient and intelligent life style.

[0020] Therefore, the clothes drying device can realize the purposes of accelerating the drying speed, facilitating the drying process, providing more functions, and improving the automation and intelligence. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 1-8 As shown, the lower plate 22 is the component that directly mounts the track 10 and supports hanging clothes. It is a rectangular frame made of materials such as aluminum alloy, with a horizontal bar in the center where the lower end of the steel cable 11 is fixed. The hanging point of the steel cable is the center of gravity of the lower plate. The track is a synchronous belt, mounted on pulleys at the four corners of the lower plate. At least one pulley is driven by the track motor 6 as the drive wheel. A cam-shaped clothes hanger 7 is installed at regular intervals on the outer side of the track. When drying clothes, individual hangers are used, with one cam-shaped clothes hanger hanging one individual hanger. The cam-shaped clothes hanger consists of a hook body 702 and a torsion arm 701. The hook body has a pin, and the torsion arm is mounted on the pin and kept in a closed state by a torsion spring. This structure is similar to a clip. A pusher at the upper end of the torsion arm is used for collecting clothes.

[0033] Automatic garment collection is accomplished by a stop block 9 mounted next to the track and a cam-shaped garment hook. The stop block is fixed on the servo motor 8. Normally, the stop block is raised and does not contact the moving cam-shaped garment hook on the track. When collecting the garment, the stop block servo motor rotates a certain angle, and the stop block moves to the position where it contacts the cam-shaped garment hook. With the force of the moving cam-shaped garment hook, the push head at the top of the torsion arm collides with the stop block, opening the torsion arm. The individual garment hangers automatically fall to the collection point. After the track rotates one full revolution, the cam-shaped garment hooks are opened one by one, and all the clothes are automatically collected and can be folded manually.

[0034] For safe operation, install button sensor 3 (A), button sensor 4 (B), and button sensor 5 (C) on the lower plate and connect them to the controller. The controller can be mounted on the lower plate, on the movable bracket 2, or on a nearby wall.

[0035] As described above, in order to ensure smooth lifting and lowering of the lower plate, two six-bar telescopic mechanisms are used to connect the steel cable between the movable support and the lower plate on both sides.

[0036] The moving bracket is also a rectangular frame structure, but it has a part similar to a handle on the upper side, which is used to install and fix the ratchet winding mechanism 13, the nut block 18 and the two sliding blocks 21. The ratchet winding mechanism is a component that ensures the lifting of the lower disc. It can realize the stop of the lower disc at any position within the lifting range without sliding.

[0037] As described above, the ratchet winding mechanism includes steel wire 11, ratchet 1302 connected with the capstan 1306, ratchet teeth 1303, ratchet cam 1304, ratchet housing 1309 and other components. The connected ratchet and capstan are installed in the ratchet housing through their shafts and are driven by the winding motor 1308. The ratchet is equipped with ratchet teeth below, which is a pair of teeth that respectively support the two sides of the ratchet so that it cannot rotate. The ratchet cam is installed in the middle of the tooth pair, and the ratchet cam is installed on the cam steering wheel 1301 and swings left or right. The tooth pair is supported by two return springs 1305 to maintain its normal state inward. The steel wire is wound on the capstan.

[0038] When the lower disc needs to rise, the cam steering wheel drives the ratchet cam to swing left, pushes away the left ratchet, and allows the winding motor to drive the ratchet to rotate counterclockwise without reversing. When the lower disc rises to the predetermined position, the winding motor stops and the cam steering wheel returns to its original position. The left ratchet resets and locks the ratchet, so the lower disc cannot be lifted or lowered. When the lower disc needs to descend, the cam steering wheel drives the ratchet cam to swing right and release the ratchet. At the same time, the winding motor rotates clockwise and the lower disc descends. When the lower disc descends to the predetermined position, the winding motor stops and the cam steering wheel returns to its original position. The right ratchet resets and locks the ratchet, so the lower disc cannot be lifted or lowered. In this way, the lower disc can be kept stable and safe at any position. The winding motor is installed on the winding motor seat 1307, and the winding motor seat is fixed on the ratchet housing.

[0039] The lead screw 16 is a screw that cooperates with the nut block 18. It is driven by the lead screw motor 1. When the lead screw rotates, the nut block installed on it drives the moving bracket 2 to move in a certain direction. When the lead screw motor reverses, the nut block drives the moving bracket to move in the opposite direction, thereby realizing the translation function of the moving bracket. The lead screw is configured with a light shaft 15 on both sides, and the light shaft is inserted into the sliding block 21 to slide, thereby keeping the moving bracket moving stably and balanced in force.

[0040] The light shaft and the lead screw are both installed and fixed on the ceiling or another bracket by connecting bearings 14. In this way, the entire intelligent clothes drying rack can be installed on the ceiling of the home balcony to lift or translate.

[0041] In order to change the position of the clothes according to the strength of the light, obtain the best drying effect, and ensure the safety of the action, a light intensity sensor (not shown in the figure), a raindrop sensor 17 and a limit sensor 23 are installed on the moving bracket. The whisk sensor 19 serves as the reference origin of the movement of the moving bracket and is installed on the ceiling.

[0042] Each motor, each sensor and the controller are electrically connected to realize intelligent control.

[0043] The controller is also called control mainboard or single-chip microcomputer, Basra main control board plus BigFish expansion board are selected, Basra is a development board based on Arduino open source scheme, can accept external environment data through various sensors, and can feedback and respond to environmental changes through control of various servo motors, lead screws, winding motors, track motors and other sensors. The main control board can be selected on the market. Refer to the instruction manual for installation, and program and adjust according to specific control needs.

[0044] According to the function type, the present application has a lifting function module, a light finding module, a rain avoiding function module and a convenient drying and clothes collecting function module. The three modules cannot interfere with each other, otherwise the stability of the intelligent drying system will be affected. It follows and meets the following logic:

[0045] Only when it is in the original position, the up and down lifting function is executed;

[0046] Only when the drying part is in the upper limit position, the automatic light finding and automatic rain avoiding functions are executed;

[0047] Only when the drying part is in the lower limit position, the convenient drying and one-key clothes collecting functions are executed;

[0048] Only when there is no rain, the automatic light finding function is executed, and the automatic light finding function is not executed when the automatic rain avoiding function is executed;

[0049] When the convenient drying function is executed, the one-key clothes collecting function is not executed, and when the one-key clothes collecting function is executed, the convenient drying function is not executed;

[0050] During the execution of the up and down lifting function, the automatic light finding, rain avoiding, convenient drying and one-key clothes collecting functions are not executed.

[0051] According to the programming rules of the controller single-chip microcomputer and the specific requirements of the present application, as well as the above-mentioned logical rules, the control program is edited and input into the single-chip microcomputer, and the debugging is normal, which can be used.

[0052] The unmentioned parts and symbols are as described above.
