Description

Technical Field

[0001] The present invention relates to the technical field of smart home, and specifically to an environment-adaptive automatic unfolding clothes hanger and a control method therefor. Background Art

[0002] With the improvement of living quality, people's interest in smart drying has gradually increased. However, the clothes hangers on the market generally have a single function and only have the simple function of carrying clothes, which does not meet the needs of modern life and severely limits the application value of the clothes hanger.

[0003] To solve the above problems, a Chinese invention patent with the authorization announcement number CN215481834U discloses "a clothes drying machine". The clothes drying machine is designed with a telescopic bracket. After the telescopic bracket is retracted, it is located at the bottom of the main body of the clothes drying machine. It adopts a scissor arm telescopic mechanism, which has a stable structure and solves the problem of time-consuming and laborious manual drying.

[0004] However, this clothes drying machine fails to comprehensively consider the problem that when the weather changes, it is often necessary to manually dry and collect clothes, and it fails to meet people's pursuit of comfort in use, such as convenient use, accelerated drying, and clothes management. Summary of the Invention

[0005] The purpose of the present invention is to provide an environment-adaptive automatic unfolding clothes hanger and a control method therefor to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An environment-adaptive automatic unfolding clothes hanger, including an upper box body, a telescopic device, a lower box body, an environment detection system, a cleaning and sterilization system, and a control unit. Among them, the lower end of the upper box body is connected to the upper end of the lower box body, the right side of the lower box body is connected to the left end of the telescopic device, and the environment detection system is located inside the upper box body.

[0007] The upper box body is fixedly installed on the wall through expansion bolts and is used to adjust the telescopic device and the rotation movement of the lower box body of the clothes hanger. The upper box body includes a driving gear, a driven gear, a motor 1, and a fan. The upper outer shell and the upper outer cover are respectively arranged at the top of the side of the upper box body. The motor 1 drives the driving gear to move, so that the driven gear makes a corresponding rotational movement to adjust the angle of the clothes hanger.

[0008] The telescopic device is connected to the lower box body through a linkage plate and is used to adjust the telescopic movement of the clothes hanger. The telescopic device includes an electric push rod, a cross bar, a clothes rod, a support bar, and a chute. The electric push rod drives the movement of the support bar through the push rod, thereby driving the cross bar to contract in a scissor arm manner.

[0009] The lower box body includes a sliding rod, a lead screw, a lower outer shell, an upper support, a lead screw nut, a second motor, an upper coupling, a lower coupling, a lower support, and a linkage plate. The lower outer shell is located outside the lower box body. The lower box body is connected to the upper box body through the upper coupling to adjust the lifting action of the drying rack. The lead screw and the lead screw nut are driven by the second motor to achieve the upward and downward movements. The upper support is arranged at the upper end of the lower box body, and the lower support is arranged at the lower end of the lower box body. The number of sliding rods is two, located on both sides in front of the upper support and the lower support, and the lead screw is located in the middle. One end is connected to the second motor at the bottom through the lower coupling. And through the connection of the lower coupling, the output torque of the second motor is converted into the driving force for the lead screw and the lead screw nut to achieve the upward and downward movements. There is a brake component on the second motor. When powered off, the rotating shaft of the second motor can be held to prevent it from rotating for protection, so that the lead screw nut remains in place without falling off.

[0010] The environmental detection system is used to detect and give early warnings about the drying environment, and includes a temperature sensor, a humidity sensor, an air quality sensor, a weather warning device, and a gravity sensor.

[0011] The cleaning and sterilization system is used to clean the surface of clothes and includes a disinfection device and an active oxygen negative ion generator.

[0012] The control unit processes the detection results of the environmental detection system and performs corresponding feedback operations through the motion system.

[0013] Preferably, the fan includes a fan body, fan blades, and a corresponding accelerated air-drying module for shortening the drying time of clothes.

[0014] Preferably, the clothes rod is installed in the installation hole in the middle of the cross bar, and the small holes on adjacent clothes rods are arranged in a staggered manner to prevent clothes from piling up.

[0015] Preferably, the cross bar is installed in the form of two rods clamping one bar. 5 to 8 groups of cross bars can be installed to adapt to different numbers of users. The end of the first group of cross bars is connected through a support bar, and this support bar moves restrictively in the chute, thereby driving the telescopic movement of the cross bar.

[0016] Preferably, the size of the chute matches the movement distance of the push rod of the electric push rod, and the installation position of the chute needs to meet the requirement that the limit angle between the cross bar and the vertical position of the push rod of the electric push rod in the extended state of the cross bar is 45 degrees.

[0017] Preferably, the lead screw is a ball screw. The lead screw nut is connected to the linkage plate through a fixed support, so that the lead screw nut and the telescopic device move synchronously. Through the connection of the lower coupling, the output torque of the second motor is converted into the driving force for the lead screw and the lead screw nut to move up and down, thus realizing the function of saving time and effort when hanging and taking clothes.

[0018] Preferably, the motion system includes a rotating mechanism, a lifting mechanism, and a telescopic mechanism.

[0019] Preferably, the temperature sensor is used to monitor the temperature of the drying environment in real time. When the environmental temperature is lower than the annual average temperature of the user's location and the season, the temperature sensor sends a signal to the control unit, and the control unit controls the drying rack to take the clothes indoors.

[0020] Preferably, the humidity sensor is used to detect the environmental humidity. When the environmental humidity is greater than 70%RH, the clothes are taken indoors and the accelerated air-drying module is turned on. The weather warning device is used to obtain the future weather through networking and determine whether to dry clothes according to the weather changes. The gravity sensor is used to detect whether the sub-mechanisms of the drying rack are normally connected.

[0021] Preferably, the cleaning and sterilization system is used for sterilization, disinfection, and cleaning of clothes before and after drying.

[0022] Preferably, the control unit processes the parameters fed back by each module and issues instructions for the next actions of each module, which are used to instruct and control the opening and closing of the drying rack and connect with the cleaning and sterilization system and the environmental monitoring system to realize the intelligent escort of clothes.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. For this environment-adaptive automatic unfolding drying rack and control method, by setting up an environmental detection system, not only can the drying environment be detected, but also the drying state can be adjusted through the environmental detection system, so that the clothes are in a suitable environment, which helps the clothes to be more comfortable to wear. Through the cleaning and sterilization system, the sterilization and disinfection of clothes can be realized. Through the gravity sensor, when the value is abnormal, an alarm response is given to check whether the drying rack is abnormally loose.

[0025] 2. For this environment-adaptive automatic unfolding drying rack and control method, it is connected with the user through the communication module, so that users with a fast-paced life, who often go out early and return late, and who are not at home for a long time will not let the clothes get damp in the dark due to forgetting to dry or collect the clothes. Moreover, through the autonomous control of the environmental detection system, when the weather changes, users do not need to subjectively judge when to dry or collect clothes; in rainy weather, people will not let the clothes be wet by rain because they forget to collect the clothes.

[0026] 3. The environment-adaptive automatic unfolding clothes hanger and its control method can achieve multi-degree-of-freedom automatic adjustment in multiple angles and directions, with a higher degree of intelligence. It can complete three actions: telescoping, lifting, and rotating, improving the efficiency of drying clothes and greatly reducing the labor cost of manual drying. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-5 , the present invention provides a technical solution: an environment-adaptive automatic unfolding clothes hanger, including an upper box body, a telescopic device, a lower box body, an environment detection system, a cleaning and sterilization system, and a control unit.

[0035] See Figure 2, the upper box body is fixedly installed on the wall through expansion bolts, and is used to adjust the telescopic device of the drying rack and the rotation of the lower box body. The upper box body includes an upper outer shell 4, an upper outer cover 5, a driving gear 15, a driven gear 14, a first motor 16, and a fan. The upper outer shell 4 and the upper outer cover 5 are respectively arranged at the top of the side surface of the upper box body. The first motor 16 drives the driving gear 15 to move, so that the driven gear 14 makes corresponding rotational motion, which is used to adjust the angle of the drying rack. The fan includes a fan body 12, fan blades 13 and a corresponding accelerated air-drying module, which is used to shorten the drying time of clothes.

[0036] See Figures 1-4 , the telescopic device is connected to the lower box body through a linkage plate 7, and is used to adjust the telescopic movement of the drying rack. The telescopic device includes an electric push rod 6, a first cross bar 1, a second cross bar 2, a clothes rod 3, a support bar 24, and a chute 8. The electric push rod 6 drives the movement of the support bar 24 through a push rod 23, so as to drive the first cross bar 1 to contract in a scissor-arm manner. For example, after the electric push rod 6 receives an execution instruction, it pushes downward to make the first cross bar 1 in a contracted state. After the clothes are hung, when it receives the execution instruction again, it pushes upward to make the first cross bar 1 in an unfolded state, that is, the state of drying clothes.

[0037] See Figure 3 , the lower box body includes a sliding rod 9, a lead screw 10, a lower outer shell 11, an upper support 18, a lead screw nut 19, a second motor 22, an upper coupling 17, a lower coupling 20, a lower support 21 and a linkage plate 7. The lower outer shell 11 is located outside the lower box body. The lower box body is connected to the upper box body through the upper coupling 17, and is used to adjust the lifting movement of the drying rack. The lead screw 10 and the lead screw nut 19 are driven by the second motor 22 to realize the upward and downward movements. The upper support 18 is arranged at the upper end of the lower box body, and the lower support 21 is arranged at the lower end of the lower box body. The number of sliding rods 9 is two, which are located on both sides in front of the upper support 18 and the lower support 21, while the lead screw 10 is located in the middle, and one end is connected to the second motor 22 at the bottom through the lower coupling 20. And through the connection of the lower coupling 20, the output torque of the second motor 22 is converted into the driving force for the lead screw 10 and the lead screw nut 19 to realize the upward and downward movements. There is a brake component on the second motor 22. When the power is off, the rotating shaft of the second motor 22 can be held to prevent it from rotating for protection, so that the lead screw nut 19 remains in place without falling off.

[0038] See Figure 3, the lead screw 10 is a ball screw. The lead screw nut 19 is connected to the linkage plate 7 through a fixed support, so that the lead screw nut 19 moves synchronously with the telescopic device. The lead screw 10 is made of stainless steel or alloy steel. The lead screw nut 19 is made of copper material that can bear large loads, has a small friction coefficient, and has a certain self-lubricating effect. Through the connection of the lower coupling 20, the output torque of the second motor 22 is converted into the driving force for the lead screw 10 and the lead screw nut 19 to move up and down, thus realizing the function of saving time and effort when hanging and taking clothes. Among them, there is a brake assembly on the second motor 22. When power is cut off, the rotating shaft of the second motor 22 can be held to prevent it from rotating for protection, so that the lead screw nut 19 remains in place without falling off.

[0039] See Figure 5 , the environmental detection system is used to detect and give early warnings about the drying environment. This environmental detection system is located inside the upper box body and includes a temperature sensor, a humidity sensor, an air quality sensor, a weather warning device, and a gravity sensor. The gravity sensor is used to give an alarm response when the value is abnormal to check whether the clothes dryer is installed abnormally loose. The control unit processes the detection results of the environmental detection system and performs corresponding feedback operations through the motion system. The motion system includes a rotating mechanism, a lifting mechanism, and a telescopic mechanism. The rotating mechanism is the main actuator for adjusting the overall spatial angle of the clothes dryer to rotate. The lifting mechanism is the main mechanism for the vertical movement of the clothes dryer. The telescopic mechanism is required to be the main mechanism for the clothes to extend and retract on the balcony side. Among them, each sub-mechanism works independently without affecting each other.

[0040] See Figure 5 , the cleaning and sterilization system is used to clean the surface of clothes and includes a disinfection device and an active oxygen negative ion generator. The disinfection device is filled with alcohol with a concentration of 70% to disinfect and clean the surface of clothes. The active oxygen negative ion generator can generate ozone. The active oxygen negative ion sterilization in the form of gas can achieve all-round and non-dead-angle cyclic sterilization. Moreover, the active oxygen will only decompose into oxygen during the sterilization process in the shoes, without any other chemical residues and without causing any harm to the human body. For example, when ozone with a concentration of 4mg / L acts for 1 minute, the killing rate of Candida albicans is 99.8%, and the killing rate can reach 100% when it acts for 3 minutes; when ozone with the same concentration acts on Aspergillus fumigatus for 5 minutes, the killing rate is 99.5%.

[0041] See Figure 4, The clothes rod 3 is installed in the mounting holes in the middle of the first cross bar 1 and the second cross bar 2. The clothes rod 3 is made of plastic material. The small holes on adjacent clothes rods are arranged in a staggered manner to prevent clothes from piling up. The cross bars are installed in the form of two rods clamping one bar. 5 to 8 groups of cross bars can be installed to adapt to different numbers of users. The end of the first group of cross bars is connected by a support bar 24. The support bar 24 makes a restricted movement in the chute 8, thereby driving the telescopic movement of the cross bars.

[0042] See Figure 4 , The size of the chute 8 matches the movement distance of the push rod 23 of the electric push rod 6. The installation position of the chute 8 needs to meet the requirement that the limit angle between the cross bar and the vertical position of the push rod 23 of the electric push rod 6 in the extended state of the cross bar is 45 degrees.

[0043] See Figure 5 , The temperature sensor is used to monitor the temperature of the drying environment in real time. When the environmental temperature is lower than the annual average temperature of the user's location and the current season, the temperature sensor sends a signal to the control unit, and the control unit controls the drying rack to retract the clothes indoors. The humidity sensor is used to detect the environmental humidity. When the environmental humidity is greater than 70%RH, the clothes are retracted indoors and the accelerated air-drying module is turned on. The weather warning device is used to obtain the future weather through networking and judge whether to dry clothes according to the weather changes. The control unit processes the parameters fed back by each module and issues instructions for the next actions of each module.

[0044] See Figures 1-5 , The working principle of the environment-adaptive automatic unfolding drying rack and control method of the present invention is:

[0045] During operation, the environmental detection system works, detects the environmental humidity, environmental temperature and environmental air quality of the drying environment respectively, and transmits the detection results to the control unit. The control unit controls the motion system to adjust the drying rack so that the drying environment is within a suitable range, so that the clothes will not become damp and breed mold due to weather changes. The control unit can also send the information of the clothes environment status to the user's mobile phone client through the communication module, and the user can adjust when to dry the clothes. Among them, before and after drying the clothes, the clothes are cleaned and disinfected by the cleaning and sterilization system.

[0046] See Figures 1-5 , The working process of the environment-adaptive automatic unfolding drying rack and control method of the present invention is:

[0047] Step 1: The second motor 22 works, drives the lead screw nut 19 to rotate, and the linkage plate 7 connected to the lead screw nut 19 moves downward synchronously. When it reaches the limit position, the electric push rod 6 starts, drives the first cross bar 1 to unfold, and the user can place the clothes to be dried on the clothes rod 3.

[0048] Step 2: After the user places the clothes to be dried on the clothes rod 3, the gravity sensor on the cross bar 1 detects that the gravity has not changed, and the electric push rod 6 starts again to drive the cross bar 1 to contract.

[0049] Step 3: After the cross bar 1 contracts to the limit position, the motor 22 works again to drive the lead screw nut 19 to rotate, and the linkage plate 7 connected to the lead screw nut 19 moves upward synchronously. At this time, the cross bar is still in the contracted state.

[0050] Step 4: If the environmental detection system detects that the current weather condition is suitable for drying clothes, the rotation mechanism starts, that is, the motor 16 drives the gear set to move, and through the lower coupling 20, the drying rack is driven to rotate to prepare for the cross bar 1 to extend out of the window. If the environmental detection system detects that the current weather condition is not suitable for drying clothes, such as thunderstorms, heavy snow, or plum rain weather, the rotation mechanism does not act, and the corresponding action of the telescopic mechanism in Step 5 is directly performed.

[0051] Step 5: After the lead screw nut 19 rises to the limit position and the rotation mechanism works accordingly according to the weather condition, the electric push rod 6 starts to drive the cross bar 1 to expand again, and the clothes are extended out of the window for drying. At this time, the environmental detection system is still working. When the weather changes severely, the drying rack moves in the reverse direction according to Steps 1 to 5 under the control of the control unit until the clothes are retracted into the room. Moreover, all the above steps can be manually controlled and interfered with on the user's mobile phone client.

[0052] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.
