The clothes drying rod of the clothes drying machine is generally connected to the main unit assembly through a wire rope. When the clothes drying rod needs to be hidden, the main unit assembly drives the clothes drying rod to rise through the wire rope, and the clothes drying rod is placed in the guide groove; when it is needed to be used, the main unit assembly drives the clothes drying rod to fall through the wire rope. When the clothes drying rod is pulled up into the guide groove, due to the high speed, it will bring a certain impact to the guide groove and the installation surface. In the long run, it will affect the service life of the hidden clothes drying machine, and more seriously, it will cause damage to the installation surface.

[0051] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0053] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0054] See also Figure 1 As shown, the anti-collision control method of the present invention is applied to a clothes drying machine 100. The clothes drying machine 100 includes a driving module 80, a control module 70, a positioning module 90 and a clothes drying rod assembly 40. The anti-collision control method includes:

[0055] The driving module 80 drives the drying rod assembly 40 to rise or fall, and generates a signal value according to the load on the drying rod assembly 40;

[0056] The control module 70 monitors the running speed and signal value of the driving module 80 in real time, and controls the driving module 80 to start deceleration movement at a deceleration time point corresponding to the signal value based on the signal value and the running speed; so that the speed of the driving module 80 is zero when it reaches the positioning module 90.

[0057] The anti-collision control method of the present invention will generate different signal values ​​when the load on the clothes-drying rod assembly 40 is different. The control module 70 will monitor the signal value and the running speed of the driving module 80, and control the driving module 80 to decelerate at the deceleration time point corresponding to the signal value according to the monitored signal value and the running speed, so that no matter how much the load is, the driving module 80 can be accurately controlled to decelerate to zero when it reaches the positioning module 90.

[0058] The deceleration time point is a time node pre-set in the control module 70 , or the deceleration time point is a time node corresponding to the signal value established by the control module 70 based on the relationship between the signal value and the operating speed of the drive module 80 .

[0059] The control module 70 may pre-set a plurality of deceleration time nodes according to the different loads on the drying rod assembly 40, and select the time node corresponding to the signal value for deceleration according to the monitored signal value. It may also establish the time node corresponding to the signal value in real time through calculation based on the relationship between the signal value and the operating speed of the driving module 80.

[0060] In some embodiments, the deceleration time point here can also be converted into a deceleration position set between any two stop positions 60, and the distance between the deceleration position and the stop position 60 in the forward direction of the drying rod assembly 40 is related to the signal value. For example, when the drying rod assembly 40 runs from the drying position 62 to the upper limit position 63, the distance between the deceleration position and the upper limit position 63 is related to the signal value.

[0061] In some embodiments, the driving module 80 decelerates at a uniform speed during the deceleration process. In other implementations, it may also decelerate at a non-uniform speed.

[0062] The driving module 80 decelerates at a uniform speed during the deceleration process, and the deceleration rate is related to the running speed of the driving module 80, the signal value, and the distance between the drying rod assembly 40 and the stop position at the deceleration time point. The magnitude of the signal value is positively or negatively correlated with the weight of the load.

[0063] The signal value is the current value of the driving module 80. The driving module 80 includes a motor 12. The motor 12 drives the drying rod assembly 40 to move. When the load on the drying rod assembly 40 is different, the current value generated by the motor 12 will be different. The current value is positively correlated with the load. The control module 70 controls the time point when the motor 12 decelerates according to the detected current value.

[0064] Please continue reading Figure 2 As shown, a collision avoidance control system according to a preferred embodiment of the present invention includes:

[0065] The driving module 80 includes a motor 12 and a gear 14. The motor 12 is in transmission connection with the gear 14. The motor 12 drives the drying rod assembly 40 of the clothes drying machine 100 to rise or fall through the gear 14.

[0066] The control module 70 includes a control unit 16 and a switch unit 15. The control unit 16 is electrically connected to the motor 12 to control the rotation of the motor 12. The control unit 16 includes a current detection circuit to detect the current value of the motor 12. The switch unit 15 is electrically connected to the control unit 16 to send a signal to the control unit 16.

[0067] The positioning module 90 includes a plurality of stop positions 60. When the drying rod assembly 40 runs between any two stop positions 60, the control unit 16 controls the driving module 80 to reduce the speed at the time node corresponding to the signal value detected by the driving module 80, so that when the drying rod assembly 40 reaches the next stop position 60, the speed of the driving module 80 is reduced to zero.

[0068] The positioning module 90 in the control system of the present invention is provided with a plurality of stop positions 60 during the operation of the drying rod assembly 40. The control unit 16 can control the drying rod assembly 40 to operate between any two stop positions 60, so as to facilitate users to take and hang clothes and dry clothes. In this process, when the number of clothes hung on the drying rod assembly 40 is different, the load of the drying rod assembly 40 will be different, and the signal value detected by the control unit 16 will also be different. The control unit 16 reduces the rotation speed at a preset rate according to the time node corresponding to the detected signal value, so as to ensure that when the drying rod assembly 40 is under different loads, the driving module 80 can decelerate to zero when the drying rod assembly 40 reaches the next stop position 60, so as to avoid the impact on the clothes drying machine 100, so as to avoid the damage to the ceiling caused by the drying rod assembly 40 pulling or colliding with the guide groove assembly 20 and the installation surface. The control module 70 includes a control unit 16, which is electrically connected to the driving module 80 and configured to control the driving module 80. The control unit 16 includes a current detection circuit, which is used to detect the current value of the driving module 80.

[0069] The control module 70 includes a control unit 16 . The control unit 16 is electrically connected to the driving module 80 and configured to control the driving module 80 . The control unit 16 includes a current detection circuit, and the current detection circuit is used to detect the current value of the driving module 80 .

[0070] The stop position 60 at least includes an upper limit position 63, a drying position 62 and a lower limit position 61 which are arranged in sequence from top to bottom in the vertical direction. Usually, the upper limit position 63 is located in the guide groove assembly 20. At this time, the drying rod assembly 40 is hidden in the guide groove assembly 20, which is more beautiful. The lower limit position 61 is located at a low place, which is convenient for people to hang clothes. The drying position 62 is located between the upper limit position 63 and the lower limit position 61. At this position, clothes can be better dried. By setting the above three stop positions 60, people's daily use needs can be better met.

[0071] The control module 70 includes a plurality of switch units. The switch unit 15 is electrically connected to the control unit 16 and is configured to send a signal to the control unit 16. The switch unit 15 is arranged in a one-to-one correspondence with the stop position 60. When the drying rod assembly 40 runs to the stop position 60, the switch unit 15 corresponding to the stop position 60 will be triggered. After being triggered, the switch unit 15 sends a stop signal to the control unit 16, and the control unit 16 controls the driving module 80 to stop rotating.

[0072] The driving module 80 includes a motor 12 and a gear 14 . The motor 12 is in transmission connection with the gear 14 . The motor 12 drives the drying rod assembly 40 of the clothes drying machine 100 to rise or fall through the gear 14 .

[0073] The drying position switch 151 and the lower limit switch 152 are installed in the driving module 80 and are movably connected to the gear 14. The gear 14 is equipped with a first touch rod 141 and a second touch rod 142. When the drying rod assembly 40 moves to the drying position 62, the first touch rod 141 triggers the drying position switch 151. When the drying rod assembly 40 moves to the lower limit 61, the second touch rod 142 triggers the lower limit switch 152. When the drying rod assembly 40 moves to the drying position 62, the first touch rod 141 on the gear 14 will abut against the drying position switch 151 at this time, triggering the drying rod position switch. When the drying rod assembly 40 moves to the lower limit 61, the second touch rod 142 on the gear 14 will abut against the lower limit switch 152 at this time, triggering the lower limit switch 152.

[0074] The driving rod 1511 of the drying position switch 151 is provided with an arc portion 1512 for contacting the first contact rod 141. When the drying rod assembly 40 descends from the upper limit position 63 to the lower limit position 61 and rises from the lower limit position 61 to the upper limit position 63, it will pass through the drying position 62. Correspondingly, during the descent of the drying rod assembly 40, the motor 12 drives the gear 14 to rotate in the first direction. During the ascent of the drying rod assembly 40, the motor 12 drives the gear 14 to rotate in the second direction opposite to the first direction. During this process, the first contact rod 141 on the gear 14 needs to trigger the drying position switch 151. Here, the driving rod 1511 on the drying position switch 151 is provided with an arc portion 1512. Only through the design of the arc portion 1512 can the gear 14 smoothly trigger the drying position switch 151 regardless of rotating in the first direction or the second direction.

[0075] The driving module 80 includes a Hall sensor 13, which is electrically connected to the control unit 16 for detecting the rotational speed of the motor 12 and outputting a pulse signal. The control unit 16 determines and controls the rotational speed of the motor 12 based on the pulse signal. In order to prevent errors in the time node when the control unit 16 controls the deceleration of the motor 12, a Hall sensor 13 is also provided in the driving module 80. The Hall sensor 13 is directly connected to the output shaft of the motor 12. The rotational speed of the motor 12 can be detected through the Hall sensor 13. The control unit 16 receives the pulse signal sent by the Hall sensor 13, determines the rotational speed of the motor 12 accordingly, and adjusts and optimizes the deceleration rate of the motor 12 according to the detected rotational speed to ensure a better deceleration effect.

[0076] Preferably, when the drying rod assembly 40 moves from the drying position 62 to the upper limit position 63, the control unit 16 controls the driving module 80 to drive the drying rod assembly 40 to decelerate. When the drying rod assembly 40 moves from the upper limit position 63 / the lower limit position 61 to the drying position 62 or from the drying position 62 to the lower limit position 61, the control unit 16 controls the driving module 80 to drive the drying rod assembly 40 to run at a uniform speed.

[0077] When the drying rod assembly 40 moves from the drying position 62 to the upper limit position 63, because it will make rigid contact with the guide groove assembly 20, the damage caused by the collision is relatively large. Therefore, it can be set here that only when the drying rod assembly 40 is in the rising process, in the process of moving from the drying position 62 to the upper limit position 63, the control unit 16 controls the driving module 80 to drive the drying rod assembly 40 to slow down. In the process of the drying rod assembly 40 moving to the upper limit position 63, the rising speed of the drying rod assembly 40 is gradually slowed down, and when it finally reaches the upper limit position 63, the rising speed is slowed down to zero to stop the movement. When running in other intervals, such as when the drying rod assembly 40 is rising from the lower limit position 61, the rising speed of the drying rod assembly 40 is gradually slowed down. When the drying rod assembly 40 is finally reached, the rising speed is slowed down to zero to stop the movement. When the drying rod assembly 40 reaches the drying position 62, and when it descends from the upper position 63 to the drying position 62 and from the drying position 62 to the lower limit position 61, the drying rod assembly 40 is set to run at a uniform speed, which can bring a better user experience. During the entire process of the drying rod assembly 40 descending and the process of rising from the lower limit position 61 to the drying position 62, the drying rod assembly 40 can run at a faster speed, and the user does not need to wait for a long time during use. During the process of rising from the drying position 62 to the upper limit position 63, the drying rod assembly 40 decelerates, which effectively avoids the impact on the guide groove assembly 20 and the ceiling, thereby extending the service life of the clothes drying machine 100.

[0078] The driving module 80 includes a motor 12, which is connected to the drying rod assembly 40 through a cable. The motor 12 is controlled to rotate in a first direction or a second direction to drive the drying rod assembly 40 to rise or fall, and the rotation speed of the motor 12 is controlled to drive the drying rod assembly 40 to run at a constant speed or at a reduced speed.

[0079] The control module 70 also includes a remote control unit 71 and a receiving unit 72. The receiving unit 72 receives the wireless signal sent by the remote control unit 71, converts it into a control signal recognizable by the control unit 16, and then sends it to the control unit 16. The control unit 16 controls the driving module 80 to drive the drying rod assembly 40 to rise or fall according to the received control signal. In order to facilitate user operation, the control module 70 is provided with a remote control unit 71 and a receiving unit 72. The remote control unit 71 can be set as a remote control. The user sends a wireless signal in a wireless manner through the remote control. The receiving unit 72 receives the wireless signal and converts it into a control signal recognizable by the control unit 16, that is, the operation of the drying rod assembly 40 can be controlled in a wireless manner, and the design is more humane and intelligent.

[0080] The upper limit position 63 is located at the upper limit switch 22 correspondingly arranged in the guide groove assembly 20 of the clothes drying machine 100. When the drying rod assembly 40 moves to the upper limit position 63, that is, touches the upper limit switch 22, the upper limit switch 22 sends a signal to the control unit 16, and the control unit 16 controls the driving module 80 to stop driving. The upper limit switch 22 is arranged in the guide groove assembly 20. When the drying rod assembly 40 rises and hides in the guide groove assembly 20 to reach the upper limit position 63, it will touch the upper limit switch 22. The upper limit switch 22 will send a signal to the control unit 16, and the control unit 16 and the control motor 12 will reduce the speed to zero. The upper limit switch 22 includes a fixing portion 221 and a tail portion 222 extending from the fixing portion 221 to the direction of the drying rod assembly 40, and the fixing portion 221 is fixedly connected to the guide groove assembly 20.

[0081] The control unit 16 may adopt an MCU controller, which has rich instructions and can fully meet various requirements of the operation of the drying rod assembly 40, effectively reducing the manufacturing cost.

[0082] Please continue reading Figures 3 to 9 As shown, a clothes drying machine 100 according to a preferred embodiment of the present invention includes the above-mentioned anti-collision control system.

[0083] The clothes drying machine 100 further includes:

[0084] The host assembly 10 is used for fixed installation on the installation surface, and includes a driving module 80, a control module 70 and a positioning module 90;

[0085] The guide groove assembly 20 is fixedly connected to the main assembly 10;

[0086] The drying rod assembly 40 is arranged below the main assembly 10 and is flexibly connected to the main assembly 10. The main assembly 10 is configured to provide traction for the drying rod assembly 40 to rise or fall, so that the drying rod assembly 40 moves downward to the outside of the guide groove assembly 20 or moves upward to the inside of the guide groove assembly 20.

[0087] In some embodiments, the guide groove assembly 20 has a accommodating cavity 21, the upper limit switch 22 is located in the guide groove assembly 20, and a damping device 30 is also provided in the guide groove assembly 20. After the drying rod assembly 40 is accommodated in the accommodating cavity 21, it is decelerated by the damping device 30 and abuts against the upper limit switch.

[0088] The clothes drying machine 100 controls the rising or falling process of the drying rod assembly 40 through the driving module 80, the control module 70 and the positioning module 90 integrated in the main unit assembly 10. When there is no clothing hanging on the drying rod assembly 40 and it needs to be hidden in the accommodating cavity 21 in the guide groove assembly 20, the motor 12 in the driving module 80 can be controlled by the control module 70 to rotate at a reduced speed when the drying rod assembly 40 moves from the drying position 62 to the upper limit position 63, so as to drive the drying rod assembly 40 to rise at a reduced speed. When rising to the upper limit position 63, the rotation speed of the motor 12 is zero, so that the drying rod assembly 40 stops rotating. In this way, the impact and collision on the guide groove assembly 20 can be minimized, the guide groove assembly 20 and the ceiling can be effectively protected, and the service life of the clothes drying machine 100 can be extended.

[0089] The clothes drying machine 100 also includes a lighting unit. The main unit component 10 is provided with a lighting driver 17 for driving the lighting unit for lighting, so as to facilitate the user to use the clothes drying machine in poor light conditions.

[0090] The damping device 30 includes a damping block 32 and a bracket 31. The bracket 31 is fixedly connected to the guide groove assembly 20, and a slot (not shown) is provided on the side of the bracket 31 close to the drying rod assembly 40. The damping block 32 is snapped into the slot and at least partially exposed from the slot. When the drying rod assembly 40 rises toward the main assembly 10, the damping block 32 elastically abuts against the drying rod assembly 40.

[0091] In order to better install the damping device 30 in the guide groove assembly 20, the damping device 30 is fixedly connected to the guide groove assembly 20 through the bracket 31, and the damping block 32 is directly clamped in the slot at the lower end of the bracket 31. Through the set slot, there is no need to assemble the damping block 32 through other parts, and the overall structure is more compact. The part of the damping block 32 exposed outside the slot is used to abut against the drying rod assembly 40 when it is rising.

[0092] After the drying rod assembly 40 is accommodated in the accommodating chamber 21, the damping device 30 is limitedly abutted against the drying rod assembly 40. By installing the damping device 30, the drying rod assembly 40 will first abut against the damping device 30 when it rises into the guide groove assembly 20, so as to further reduce the rising speed of the drying rod assembly 40. At the same time, by installing the damping device 30, even if the control module 70 or other modules fail, the drying rod assembly 40 can be prevented from causing collision and impact on the guide groove assembly 20 during the rising process, making the clothes drying machine 100 more reliable.

[0093] Preferably, the damping block 32 is made of a silicone block, which can effectively reduce the impact of the drying rod assembly 40 on the guide groove assembly 20. At the same time, the silicone block generates less noise and vibration, has strong durability, and is conducive to protecting the overall structure of the clothes drying machine 100 and extending the service life of the product. In other embodiments, the damping block 32 of rubber or resin material can also be used, and the present invention does not impose any limitation on this.

[0094] The motor 12 passes through the fixed pulley 11 through the flexible member 50 and is connected to the drying rod assembly 40. The motor 12 drives the drying rod assembly 40 to rise or fall through the flexible member 50. Fixed pulleys 11 are provided at both ends of the host assembly 10. One end of the flexible member 50 is connected to the drying rod assembly 40, and the other end passes through the fixed pulley 11 and is connected to the motor 12. When it is necessary to control the drying rod assembly 40 to rise, the motor 12 is started to rotate forward. At this time, the flexible member 50 passing through the fixed pulley 11 drives the drying rod assembly 40 to rise under the rotation of the motor 12. When it is necessary to control the drying rod assembly 40 to fall, the motor 12 is started to rotate reversely, and the motor 12 drives the drying rod assembly 40 to fall through the flexible member 50.

[0095] In summary, the anti-collision control method, anti-collision control system and clothes drying machine 100 of the present invention, the upper limit position 63, the drying position 62 and the lower limit position 61 three different stop positions 60 are set in the positioning module 90, and the control unit 16 is used to control the drying rod assembly 40 to be able to decelerate and run at a constant speed when running between any two stop positions 60. At the same time, the control module 70 monitors the signal value generated according to the load of the drying rod assembly 40 and the running speed of the driving module 80 in real time, and controls the driving module 80 to decelerate at the deceleration time point corresponding to the signal value according to the monitored signal value and running speed, so that the running speed of the driving module 80 of the drying rod assembly 40 is reduced to zero when it reaches the next stop position 60, thereby effectively avoiding collision and impact on the guide groove assembly 20, protecting the ceiling and the clothes drying machine 100, and bringing a better user experience.

[0096] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
