[0057] Embodiment 1

[0058] See also Figures 1 to 5The embodiment of the present invention provides a clothes drying device, including a main body 10, a clothes drying assembly 20 and a drying assembly 30. The main body 10 is provided with an air inlet 11 and a main air duct 12 connected to the air inlet 11; the clothes drying assembly 20 is provided with multiple groups, and the multiple groups of clothes drying assembly 20 are arranged at intervals around the circumference of the main body 10, and each group of clothes drying assembly 20 forms a secondary air duct 21, and the secondary air duct 21 is selectively connected to the main air duct 12; each group of clothes drying assembly 20 includes a clothes drying rod 22 and a clothes drying rack 23, the clothes drying rod 22 is connected to the main body 10, and a gravity sensor is arranged between the clothes drying rack 23 and the clothes drying rod 22, and the clothes drying rack 23 can move between an initial position and an operating position relative to the clothes drying rod 22; the drying assembly 30 is arranged in the main air duct 12, and the drying assembly 30 sucks air through the air inlet 11 and blows air to the secondary air duct 21 through the main air duct 12. Among them, a ventilation valve that can be opened or closed can be provided at the connection between the secondary air duct 21 and the main air duct 12.

[0059] The weight change of the clothes drying rack 23 is detected by the gravity sensor, and it can be determined whether clothes are placed on the clothes drying rack 23 according to the weight change. Since the auxiliary air duct 21 is formed in each set of clothes drying components 20, and the auxiliary air duct 21 is selectively connected with the main air duct 12, for the clothes drying rack 23 with clothes placed, the corresponding auxiliary air duct 21 can be controlled to open to connect with the main air duct 12, and for the clothes drying rack 23 without clothes placed, the corresponding auxiliary air duct 21 can be controlled to close to disconnect from the main air duct 12. The drying component 30 sucks air through the air inlet 11 and blows air to the auxiliary air duct 21 through the main air duct 12, and only blows air to the opened auxiliary air duct 21, so that the drying is targeted and energy waste is avoided. According to the weight change, it can be determined whether the clothes on the clothes drying rack 23 are dried. For the clothes that are dried to move from the initial position to the operating position, the change in the position of the clothes drying rack 23 is convenient for the user to find and take it away in time, and to vacate the clothes drying rack 23 in time to make full use of the clothes drying position.

[0060] In this embodiment, the operating position is set below the initial position, and the height of the operating position is relatively low, which is convenient for users to take and put clothes. In other embodiments, the operating position can also be set according to actual needs, such as the operating position is set to one side of the initial position in the horizontal direction, or the operating position is set obliquely below the initial position, as long as it can be easily distinguished from the initial position.

[0061] A first lifting assembly 40 is provided between the clothes drying rod 22 and the clothes drying rack 23, and the first lifting assembly 40 can drive the clothes drying rack 23 to rise and fall. In this embodiment, the first lifting assembly 40 includes a first lifting rope and a first winding wheel, the first winding wheel is provided on the clothes drying rod 22 and can rotate around its own axis, and the first lifting rope is wound around the first winding wheel and connected to the clothes drying rack 23. The first winding wheel can be driven by a first motor. Since each clothes drying rack 23 can move independently, multiple groups of the first lifting assembly 40 are provided, and a group of the first lifting assembly 40 is provided for each clothes drying rack 23. In other embodiments, the first lifting assembly 40 may also include a cylinder, and the clothes drying rack 23 is driven to rise and fall by the cylinder.

[0062] The auxiliary air duct 21 may be entirely disposed on the clothes drying rod 22, or partially disposed on the clothes drying rod 22 and partially disposed on the clothes drying rack 23. In this embodiment, the auxiliary air duct 21 includes a first auxiliary air duct 211 disposed in the clothes drying rod 22 and a second auxiliary air duct 212 disposed in the clothes drying rack 23. When the clothes drying rack 23 is located at the initial position, the first auxiliary air duct 211 is connected to the second auxiliary air duct 212. Therefore, it is necessary to turn on the drying assembly 30 after the clothes drying rack 23 moves to the initial position to achieve a better drying effect.

[0063] Generally, the clothes drying rack 23 is configured to be suitable for hanging clothes. In this embodiment, the air outlet of the second auxiliary air duct 212 is in a trumpet shape, which increases the air outlet area and facilitates blowing air to the clothes on the clothes drying rack 23 over a large area.

[0064] A control module is provided in the main body 10, and the gravity sensor, the drying assembly 30, the first lifting assembly 40, etc. are all electrically connected to the control module. The control module can use existing programs and chips and other components, which are not described here. The clothes drying device also includes a terminal device, and the control module is wirelessly connected to the terminal device. The control module can receive instructions issued by the terminal device and can also send status information of the clothes drying device to the terminal device. The terminal device can be a mobile phone or a remote control.

[0065] Each clothes drying rack 23 can be moved between the initial position and the operating position under the control of the control module according to the instruction of the terminal device. For example, each clothes drying rack 23 has a corresponding number, and when the user uses the terminal device to send an ascending or descending instruction to the corresponding number, the corresponding clothes drying rack 23 ascends or descends.

[0066] Since the weight change of the clothes drying rack 23 is detected by the gravity sensor, whether clothes are placed on the clothes drying rack 23 can be determined according to the weight change, so the clothes drying rack 23 has an empty state and a non-empty state. When the user needs to dry clothes, the terminal device can send a "drying" command to the control module, and the control module controls the empty clothes drying rack 23 to move from the initial position to the operating position, so that the user can hang clothes.

[0067] The drying assembly 30 includes a fan 31 and a heater 32 , and the heater 32 is disposed between the fan 31 and the air inlet 11 .

[0068] In this embodiment, the main body 10 is a fixed integral body, and a plurality of clothes drying rods 22 are arranged at intervals around the circumference of the main body 10, so that the layout is compact and the space occupied is small. Clothes are taken and placed by lifting and lowering each clothes drying rack 23. The main air duct 12 and the auxiliary air duct 21 are selectively connected by opening or closing the ventilation valve.

[0069] In some embodiments, the secondary air duct 21 corresponding to the clothes drying rack 23 can be opened only when the clothes drying rack 23 moves to the initial position. In some embodiments, when the clothes drying rack 23 is in a position between the initial position and the operating position, the secondary air duct 21 corresponding to the clothes drying rack 23 can be opened.

[0070] The position of the clothes drying rack 23 can be detected by an existing position sensor, which is arranged on the clothes drying rod 22, and a reflector is arranged on the clothes drying rack 23. The light emitted by the transmitting part of the position sensor is emitted to the reflector and is reflected by the reflector and then returned to the receiving part of the position sensor. The working principle of the position sensor is the existing technology and will not be described in detail here.

[0071] In other embodiments, the start and stop of the drying component 30 may be automatically controlled or manually controlled. For example, there are N clothes drying racks 23 in total, and when M clothes drying racks 23 are located at the initial position and the weight value of the clothes drying racks 23 is within the first set range, the drying component 30 is turned on. Wherein, M and N are both positive integers, M is greater than or equal to k multiplied by N, and k is greater than or equal to 0.5 and less than or equal to 1.

[0072] Embodiment 2

[0073] Figures 6 to 9The second embodiment is shown, wherein the parts identical or corresponding to the first embodiment are marked with the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences between the second embodiment and the first embodiment are described. The difference is that the main body 10 is divided into several parts that can move relatively, so as to facilitate the synchronous operation of all clothes drying rods 22. Specifically, the main body 10 includes a fixed part 13 and a movable part 14, the movable part 14 is arranged at the lower side of the fixed part 13 and can move in the vertical direction relative to the fixed part 13, and the clothes drying rods 22 are connected to the movable part 14. By lifting the movable part 14 in the vertical direction, all clothes drying rods 22 can be driven to rise and fall synchronously. Since the movable part 14 is arranged at the lower side of the fixed part 13 and can move in the vertical direction relative to the fixed part 13, when it is necessary to dry clothes, the clothes drying rod 22 is lowered by the lowering of the movable part 14, so as to facilitate hanging clothes. After the clothes are hung, the clothes drying rod 22 is raised by the rising of the movable part 14 to reach a better position for drying.

[0074] The main air duct 12 includes a first main air duct 121 provided at the fixed part 13 and a second main air duct 122 provided at the movable part 14, and the first main air duct 121 is selectively connected with the second main air duct 122. When the movable part 14 is lowered relative to the fixed part 13, the first main air duct 121 is disconnected from the second main air duct 122. After the user hangs the clothes, the movable part 14 is raised relative to the fixed part 13, and the first main air duct 121 is connected with the second main air duct 122, so that the drying operation can be realized.

[0075] A second lifting assembly 50 is provided between the fixed portion 13 and the movable portion 14. The second lifting assembly 50 includes a second lifting rope 51 and a second winding wheel 52. The second winding wheel 52 is provided at the fixed portion 13 and can rotate around its own axis. The second lifting rope 51 is wound around the second winding wheel 52 and connected to the movable portion 14. The second winding wheel 52 can be driven by a second motor. By controlling the start and stop of the second motor, the movable portion 14 can be stopped at any position below the fixed portion 13. The second lifting rope 51 can have two connection ends, both of which are connected to the movable portion 14 to ensure stability.

[0076] In this embodiment, the moving part 14 is a fixed integral body, and a plurality of clothes drying rods 22 are arranged at intervals around the circumference of the moving part 14, so that the layout is compact and the occupied space is small.

[0077] As described above, the movable portion 14 is disposed at the lower side of the fixed portion 13 and can move in the vertical direction relative to the fixed portion 13, so an upper limit position and a lower limit position are set on the moving stroke of the movable portion 14. When the movable portion 14 moves to the upper limit position, the first main air duct 121 is connected to the second main air duct 122. When the first main air duct 121 is disconnected from the second main air duct 122, even if the drying component 30 is turned on, the drying effect will not be very good.

[0078] In some embodiments, a bellows is arranged between the fixed part 13 and the movable part 14, and the main air duct 12 includes a first main air duct 121 arranged at the fixed part 13 and a second main air duct 122 arranged at the movable part 14. The bellows connects the first main air duct 121 and the second main air duct 122, so that the first main air duct 121 and the second main air duct 122 are always in a connected state, and the movable part 14 can be dried when it stops at any position.

[0079] Embodiment 3

[0080] Figures 10 to 15 Embodiment 3 is shown, in which the parts identical or corresponding to those in Embodiment 2 are marked with the corresponding reference numerals in Embodiment 2. For the sake of simplicity, only the differences between Embodiment 3 and Embodiment 2 are described. The difference is that the moving part 14 includes a supporting part 141 and a rotating part 142, the supporting part 141 can move in a vertical direction relative to the fixed part 13, the rotating part 142 can rotate relative to the supporting part 141 around a first axis, and the clothes drying rod 22 is connected to the rotating part 142. The clothes drying rod 22 is driven to rotate by the rotating part 142, so that the clothes on the clothes drying rack 23 are fully in contact with the air, and the air flow can be accelerated during the rotation process, which can also increase the drying speed when not drying, and dry faster when drying.

[0081] The rotating part 142 is provided with a driven gear 143, the axis of which coincides with the first axis, and the supporting part 141 is provided with a driving gear 144 and a motor 145 connected to the driving gear 144, the driving gear 144 meshes with the driven gear 143. The driving gear 144 is driven to rotate by the motor 145, thereby driving the rotating part 142 to rotate.

[0082] The support part 141 is suspended by the second lifting rope 51, and the rotating part 142 can rotate relative to the support part 141, but cannot be separated from the support part 141, and the support part 141 provides support for the rotating part 142. Specifically, a limiting groove 1411 with a T-shaped cross section is provided on the support part 141, and a limiting protrusion 1421 with a T-shaped cross section is provided on the rotating part 142. The limiting protrusion 1421 is slidably matched with the limiting groove 1411, and the driven gear 143 is arranged in the circumference of the limiting protrusion 1421. The limiting protrusion 1421 cooperates with the limiting groove 1411 to play a limiting role, so that the rotating part 142 is suspended on the support part 141.

[0083] Regardless of whether the drying assembly 30 is turned on or not, the control module can control the rotating part 142 to rotate. The rotation of the rotating part 142 can be performed automatically. For example. There are N clothes drying racks 23 in total. When M clothes drying racks 23 are located at the initial position and the weight value of the clothes drying racks 23 is within the first set range, the control module controls the rotating part 142 to rotate. Wherein, M and N are both positive integers, M is greater than or equal to k multiplied by N, and k is greater than or equal to 0.5 and less than or equal to 1.

[0084] In some embodiments, the main body 10 includes a fixed portion and a rotating portion, and the rotating portion can rotate relative to the fixed portion around a first axis. In some embodiments, the clothes drying rack 23 is movably connected to the rotating portion, and the clothes drying rack 23 can swing in the horizontal direction to facilitate taking and hanging clothes.

[0085] Embodiment 4

[0086] Fig.16 The fourth embodiment is shown, in which the parts identical or corresponding to the first embodiment are marked with the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences between the fourth embodiment and the first embodiment are described. The difference is that an extension member 60 is provided on the main body 10, and the extension member 60 is located in the middle of the plurality of clothes drying rods 22. The extension member 60 is provided with an auxiliary air duct and a plurality of air outlets 61 connected to the auxiliary air duct, and the auxiliary air duct is selectively connected to the main air duct 12. When all the clothes drying racks 23 are hung with undried clothes, the auxiliary air duct can be opened to blow air to the clothes on each clothes drying rack 23 through the plurality of air outlets 61.

[0087] In the second embodiment, the extension member 60 may be disposed on the moving portion 14. In the third embodiment, the extension member 60 may be disposed on the rotating portion 142.

[0088] See also Fig.17 and Fig.18 In combination with the clothes drying device of any of the above embodiments, an embodiment of the present invention further provides a clothes drying control method, using the above clothes drying device, comprising:

[0089] The clothes drying rack 23 has an initial weight value M0;

[0090] Obtain the weight value M of the clothes drying rack 23;

[0091] If the weight value M of the clothes drying rack 23 is greater than M0, then the change ΔM of the weight value of the clothes drying rack 23 per unit time is obtained;

[0092] If the weight value variation ΔM is within the first set range, the clothes drying rack 23 is controlled to move to the initial position, and the drying assembly 30 and the auxiliary air duct 21 corresponding to the clothes drying rack 23 are turned on;

[0093] If the weight value variation ΔM is within the second setting range, the auxiliary air duct 21 corresponding to the clothes drying rack 23 is closed, and the clothes drying rack 23 is controlled to move to the operating position.

[0094] The initial weight value M0 of the clothes rack 23 is the weight of the clothes rack 23. If clothes are hung on the clothes rack 23, the weight of the clothes rack 23 increases. Different clothes have different weights. Therefore, when the weight value M of the clothes rack 23 is greater than M0, it is considered that clothes are hung on the clothes rack 23.

[0095] By obtaining the weight value change ΔM of the clothes drying rack 23 per unit time, the degree of dryness and wetness of the clothes can be known. If the weight value change ΔM per unit time is within the first setting range, it means that the change is large, the clothes are wet, and need to be dried. If the weight value change ΔM is within the second setting range, it means that the change is small, and the clothes are basically dry.

[0096] If the weight value M of the clothes drying rack 23 is not greater than M0, the control module detects whether it has received a drying instruction; if it has received a drying instruction, the clothes drying rack 23 is controlled to move to the operating position; otherwise, the clothes drying rack 23 is controlled to move to the initial position.

[0097] If the weight value M of the clothes drying rack 23 is greater than M1, a first alarm message is issued, indicating that the weight of the clothes on the clothes drying rack 23 is too large and exceeds the bearing range of the clothes drying rack 23, which may cause damage to the clothes drying rack 23.

[0098] To be on the safe side, if the weight value change ΔM remains within the second set range and remains unchanged within the first time period, it means that the clothes have been dried, the secondary air duct 21 corresponding to the clothes rack 23 is closed, and the clothes rack 23 is controlled to move to the operating position.

[0099] When the clothes rack 23 is in the operating position, the weight value M of the clothes rack 23 is obtained; if the weight value M of the clothes rack 23 is greater than M0 and remains unchanged within the first set time, it means that the user has not collected the clothes for a long time, and the first prompt information can be issued. If the weight value M of the clothes rack 23 is not greater than M0 and remains unchanged within the second set time, it means that the user has taken away the clothes and has not hung new clothes, and the clothes rack 23 can be controlled to move to the initial position.

[0100] Regardless of whether the weight value changes within the first set time or the second set time, the weight value M of the clothes drying rack 23 continues to be obtained. If the weight value M of the clothes drying rack 23 is greater than M0, the change ΔM of the weight value of the clothes drying rack 23 per unit time is obtained. If the weight value M of the clothes drying rack 23 is not greater than M0, it is determined whether the weight value M remains unchanged within the second set time.

[0101] Normally, when a user needs to air clothes, the user sends a command to the clothes drying device through the terminal device, and the control module controls the vacant clothes drying rack 23 to move from the initial position to the operating position. According to the change in the weight of the clothes drying rack 23, if the weight value M of the clothes drying rack 23 is greater than M0, the change ΔM of the weight value of the clothes drying rack 23 per unit time is obtained; if the change ΔM of the weight value is within the first setting range, the clothes drying rack 23 is controlled to move to the initial position, and the drying component 30 and the auxiliary air duct 21 corresponding to the clothes drying rack 23 are turned on; if the change ΔM of the weight value is within the second setting range, the auxiliary air duct 21 corresponding to the clothes drying rack 23 is closed, and the clothes drying rack 23 is controlled to move to the operating position. When the clothes drying rack 23 is in the operating position, the weight value M of the clothes drying rack 23 is obtained; if the weight value M of the clothes drying rack 23 is greater than M0 and remains unchanged within the first setting time, a first prompt message is issued. If the weight value M of the clothes drying rack 23 is not greater than M0 and remains unchanged within the second set time period, the clothes drying rack 23 is controlled to move to the initial position.

[0102] For the clothes drying device in the second embodiment, when the first main air duct 121 and the second main air duct 122 are selectively connected, when in use, it further includes: when the drying assembly 30 is in the on state, the control module controls the moving part 14 to move to the upper limit position to connect the first main air duct 121 with the second main air duct 122. When the first main air duct 121 and the second main air duct 122 are connected through the bellows, the method of use is the same as the clothes drying control method, and no matter whether the moving part 14 is at the upper limit position, the lower limit position, or any position between the upper limit position and the lower limit position, the wind in the main air duct 12 can reach the entrance of the auxiliary air duct 21.

[0103] The clothes drying device provided in the embodiment of the present invention can be used alone or in a smart home system. The smart home system includes a washing machine, and the clothes drying device is linked with the washing machine. When the washing machine finishes washing, the clothes drying device receives a "drying" instruction, and the control module controls the empty clothes drying rack 23 to move from the initial position to the operating position, so that the user can hang clothes. According to the change in the weight of the clothes drying rack 23, the empty clothes drying rack 23 moves from the initial position to the operating position after clothes are hung, so that the user can hang clothes.

[0104] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
