[0032] The main machine is provided with a power supply contact part, and the drying module is correspondingly provided with an electric receiving contact part;

[0033] When the drying rack moves upward to reach a set drying position under the control of the drying control module, the electric receiving contact part and the power supply contact part abut to realize electrical connection, so as to supply power to the hot air supply unit; the drying control module is configured to:

[0034] In the second drying mode, when the electrical receiving contact and the power supply contact are detected to be in contact to achieve electrical connection, and a drying command is received, the drying module is controlled to perform the drying action in response to the drying command.

[0035] A drying device includes a clothes rack comprising a main unit, a clothes rack that can be raised and lowered relative to the main unit, and a drying module disposed on the clothes rack; the drying device includes a drying control module, which is configured to have:

[0036] In response to the first clothes-drying command, the clothes rack is controlled to rise or fall to a first height for hanging the first item;

[0037] In response to a second clothes-drying command, the clothes rack is controlled to rise or fall to a second height for placing a second item on the drying module; and in response to a drying command, the clothes rack is controlled to rise to a preset position and perform a drying action; wherein the second height is lower than the first height.

[0038] A clothes drying rack includes a main unit, a drying rack that can be raised and lowered relative to the main unit, and a drying module disposed on the drying rack, and also includes the aforementioned clothes drying device.

[0039] A drying method is applied to a clothes drying rack, the clothes drying rack including a main unit, a drying rack that can be raised and lowered relative to the main unit, and a drying module configured on the drying rack, the drying method including:

[0040] In response to the first clothes-drying command, the clothes rack is lowered a first predetermined distance to hang the first item;

[0041] In response to a second clothes-drying command, the clothes rack is lowered a second predetermined distance to place the second item on the drying module; and in response to a drying command, the clothes rack is raised a second predetermined distance to control the drying module to perform a drying action on the second item.

[0042] Before the step of controlling the drying rack to rise a second predetermined distance in response to the drying command, the procedure also includes:

[0043] Check whether the cover of the drying module is in a closed state;

[0044] If the cover is closed, proceed with the steps of raising the drying rack and drying.

[0045] If the cover is not closed, the drying control module will not respond to the drying command, the drying rack will remain in its current position, and the drying module will not start.

[0046] Before the step of controlling the drying module to perform the drying action on the second item, the following is also included:

[0047] The system detects whether the drying module and the main unit are electrically connected. The electrical connection is achieved by controlling the drying rack to rise a second predetermined distance, so that the electrical receiving contact of the drying module abuts against the power supply contact of the main unit.

[0048] The drying action is only performed when the drying module is electrically connected to the main unit.

[0049] During the process of controlling the drying module to perform the drying action on the second item, it also includes:

[0050] If a lifting control command is received, the drying rack will be controlled to perform the corresponding lifting or lowering action, and the hot air supply unit will be controlled to stop working simultaneously.

[0051] When the drying rack is raised and lowered back to the drying position corresponding to the second predetermined distance, the drying module is controlled to resume the drying action.

[0052] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0053] 1. In this invention, by responding to different clothes-drying commands, the drying rack is controlled to descend to different predetermined distances, realizing the step-by-step operation of hanging the first item for drying and placing the second item for drying, realizing dedicated drying of the second item, avoiding interference with the regular drying function, and improving drying efficiency and space utilization.

[0054] 2. In this invention, by distinguishing between the first drying mode and the second drying mode, the drying rack automatically adjusts its lowering height according to different types of items, realizing intelligent switching between regular hanging and drying of clothes and precise placement and drying of small items. This avoids the cumbersome operation caused by manual adjustment or repeated raising and lowering by the user, and improves the efficiency of use and the human-computer interaction experience.

[0055] 3. The drying rack is divided into a first drying area and a second drying area, and the drying module is specially set up in the second drying area. This allows the regular drying and drying functions to operate separately in physical space, effectively avoiding interference between the drying process and naturally dried clothes, and meeting the different needs and user experience of the two types of items.

[0056] 4. In this invention, by setting a first predetermined distance that is less than a second predetermined distance, the drying rack can be lowered to a lower operating height when the second item to be dried is placed on it, which is more in line with the ergonomic requirements for picking up and putting down the item. At the same time, it maintains a higher position when the first item is hung, thus taking into account both the comfort and efficiency of the two types of operations.

[0057] 5. In this invention, a detachable drying module design is adopted, which allows users to flexibly choose whether to enable the drying function according to actual needs. After disassembly, it does not occupy the drying space, thereby improving the overall drying capacity and usage flexibility of the drying rack, while also facilitating cleaning, maintenance and long-term storage.

[0058] 6. In this invention, by setting an opening and closing detection module at the opening end of the drying module, the drying action is only allowed to start when the cover is completely closed, which effectively prevents hot air leakage and energy waste, avoids safety hazards caused by operational negligence, and improves the reliability and safety of the drying process.

[0059] 7. In this invention, a contact-type power supply structure is adopted between the main unit and the drying module. The electrical connection is established only after the drying rack is raised to the designated position. The electrical connection status is used as a necessary condition for starting the drying process. This ensures that the drying function is activated only when the physical position is in place and the connection is reliable, avoiding accidental start-up and power consumption under no-load conditions, and improving system energy efficiency and safety.

[0069] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0070] The present invention will be further described below through specific embodiments.

[0071] SeeFigures 1 to 5 This embodiment proposes a clothes drying device applied to a clothes rack. The clothes rack includes a main unit 20, a clothes rack 30 that can be raised and lowered relative to the main unit 20, and a drying module 10 disposed on the clothes rack 30. The clothes drying device of this embodiment includes a drying control module 21, which is configured as follows:

[0072] In response to the first clothes-drying command, the clothes rack 30 is controlled to descend a first predetermined distance for hanging the first item;

[0073] In response to a second clothes-drying command, the clothes rack 30 is controlled to descend a second predetermined distance to place the second item on the drying module 10; and in response to a drying command, the clothes rack 30 is controlled to rise a second predetermined distance to control the drying module 10 to perform a drying action on the second item.

[0074] The drying command refers to the control command used to activate the drying module 10 to perform the drying action. Its triggering methods include, but are not limited to: sending to the host 20 via remote control, sending remotely via a mobile terminal APP, voice control triggering, gesture recognition triggering, or direct triggering through the drying module 10. The first item refers to items suitable for conventional natural air drying scenarios, conforming to the hanging drying design of the drying rack 30's drying area. These items are hung after the drying rack 30 is lowered to a suitable operating height to meet the needs of natural ventilation and sunlight drying, such as clothes, pants, and bed sheets. The second item refers to a type of item requiring specific drying treatment and suitable for the dedicated placement space of the drying module 10. These items are placed after the drying rack 30 is lowered to a convenient operating position to match the drying function's application scenario and achieve efficient drying, such as underwear, socks, or handkerchiefs.

[0075] In this embodiment, the clothes drying device integrates a drying control module 21 within the host 20. This module includes a processor and a memory. The memory stores the clothes drying program, and the processor executes the program to implement related responses and control actions. The drying control module 21 responds to different clothes drying commands. Specifically, the drying control module 21 receives command signals through the communication module of the host 20. Triggering methods include, but are not limited to, remote control sending, remote sending via a mobile terminal APP, voice control triggering, gesture recognition triggering, or sending via the drying module 10. The clothes drying commands are generated either by the user's active operation based on the item's drying or heat-drying needs, or automatically generated by the device according to preset logic. Specifically, these commands include a first clothes drying command, a second clothes drying command, and a drying command, driving the drying rack 30 to rise and fall at a predetermined distance. This adapts to the operational needs of different types of items, improving ease of use. Furthermore, through the integration and height adjustment of the drying module 10 and the drying rack 30, it enables the operation of both regular drying of the first item and drying of the second item, avoiding mutual interference while ensuring the effectiveness of drying energy and improving drying uniformity.

[0076] For example, in order to achieve zoned adaptation and independent operation of different types of items, the drying rack 30 is divided into a first drying area and a second drying area; the drying module 10 is correspondingly set in the second drying area;

[0077] When the drying rack 30 descends a first predetermined distance under the control of the drying control module 21, the first drying area is used to hang the first item, which is suitable for the space and operation requirements of conventional natural drying.

[0078] When the drying rack 30 descends a second predetermined distance under the control of the drying control module 21, the second drying area is in a convenient operating position, and the second drying area is used to place the second item on the drying module 10.

[0079] For example, to optimize the overall spatial layout of the drying rack 30 and improve space utilization, the first drying area and the second drying area can adopt a design form of partial space coverage. This coverage is only an overlap in physical space and must meet the core premise of not affecting the normal use of the drying device: the covered area does not obstruct the installation and fixing structure of the drying module 10, does not hinder the opening and closing operation of the cover 11c of the drying module 10, and at the same time, it reserves operating space for the second item to be placed and the hot air circulation path when the drying module 10 is working, ensuring that the core functions of the second drying area for placing the second item and the drying module 10 performing the drying action are not interfered with in any way.

[0080] To further adapt to the different operating characteristics of the first and second items, the first predetermined distance is smaller than the second predetermined distance, so that the operating height of the drying rack 30 when it descends to the second predetermined distance is lower than the operating height when it descends to the first predetermined distance, thus adapting to the hanging requirements of the first item and the placement requirements of the second item.

[0081] For example, considering a typical ceiling height of about 2.8m, the first predetermined distance is typically set to 1.0m-1.2m, corresponding to the drying rack 30 being about 1.6m-1.8m above the ground after being lowered, which is suitable for the operation of hanging the first item; the second predetermined distance is set to 1.4m-1.6m, corresponding to the drying rack 30 being about 1.2m-1.4m above the ground after being lowered, which is suitable for placing the second item into the drying module 10, and also facilitates related operations by the user.

[0082] Once the drying rack 30 has descended to the first predetermined distance in response to the first drying command, if it receives a second drying command again, the drying control module 21 will control the drying rack 30 to descend by the difference between the second and first predetermined distances to ensure it reaches the corresponding operating height. This avoids redundant operations of resetting and descending the drying rack 30, ensuring both the lower operating height required for placing the second item and not affecting the normal drying status of items already hung in the first drying area. Similarly, once the drying rack 30 has descended to the second predetermined distance in response to the second drying command, if it receives the first drying command again, the drying control module 21 will control the drying rack 30 to rise by the difference between the second and first predetermined distances to ensure it reaches the corresponding operating height.

[0083] The drying module 10 is detachably installed on the drying rack 30. The detachable design not only facilitates daily cleaning and maintenance, but also allows it to be removed when the drying function is not needed, thus avoiding occupying the space of the second drying area and further improving the overall drying utilization rate of the drying rack 30.

[0084] See Figure 4 The clothes drying device also includes an on-site detection module 14 for detecting whether the drying module 10 is installed on the drying rack 30. Exemplarily, the on-site detection module 14 includes a magnet and a Hall switch. The magnet is positioned in the second drying area corresponding to the installation location of the drying module 10, and the Hall switch is mounted on the drying module 10. When the drying module 10 is installed in the second drying area of ​​the drying rack 30, the magnet aligns with the Hall switch and triggers an on-site detection signal, confirming that the drying module 10 is in a normal assembly state. If the drying module 10 is not installed on the drying rack 30, the Hall switch does not detect the alignment signal of the magnet, and the drying module 10 cannot respond to drying-related operation commands, but this does not affect the normal use of other drying functions of the clothes drying machine.

[0085] For example, see Figure 3 The drying module 10 includes a main body 11, a cover 11c, and a hot air supply unit 16. The main body 11 has a cavity 11a for accommodating a second item. This cavity 11a has an opening 11b, and a storage structure 15 for supporting the second item is provided within the cavity 11a. This structure can be a grid-type or tiered shelf, etc. The cover 11c is closable at the opening 11b end of the cavity 11a, used to close or open the cavity 11a. When the cover 11c is closed, it creates a relatively sealed environment in the cavity 11a. The hot air supply unit 16 is mounted on the main body 11, with its air inlet connected to the outside atmosphere and its air outlet connected to the cavity 11a, used to supply hot air into the cavity 11a to dry the second item.

[0086] In one exemplary embodiment, a sterilization unit 18 is also provided on the cover 11c of the drying module 10. The sterilization unit 18 is assembled on the side of the cover 11c facing the cavity 11a. It can be an ultraviolet sterilization lamp or other suitable sterilization structure. When the cover 11c is closed and the cavity 11a forms a relatively sealed environment, the sterilization unit 18 can be started synchronously with the hot air supply unit 16. Its effective range can cover the second item in the cavity 11a.

[0087] The clothes drying device also includes an opening / closing detection module 13, which is installed at the opening 11b end of the cavity 11a and is used to detect the opening / closing state of the cover 11c. For example, the opening / closing detection module 13 uses a microswitch, which is mounted at the opening 11b end of the cavity 11a. A trigger element 11d is provided on the cover 11c at a position corresponding to the installation position of the microswitch. When the cover 11c is closed, the trigger element 11d triggers the microswitch to output a closing signal and feeds it back to the drying control module 21. When the cover 11c is open, the trigger element 11d disengages from the microswitch, and the microswitch outputs an open signal to the drying control module 21.

[0088] Correspondingly, the drying control module 21 is configured to: when the drying rack 30 descends to the operating height corresponding to the second predetermined distance under the drive of the drying control module 21, receive the signal fed back by the opening and closing detection module 13 in real time; when the opening and closing detection module 13 detects that the cover 11c is in a closed state and receives a drying command, it responds to the drying command, controls the drying rack 30 to rise the second predetermined distance to the corresponding drying position, and triggers the hot air supply unit 16 to perform the drying action.

[0089] If the opening and closing detection module 13 detects that the cover 11c is not closed, regardless of whether a drying command is received, the drying control module 21 will not respond to the drying command, the drying rack 30 will remain in its current position, the hot air supply unit 16 will not be started and will remain closed to avoid problems such as hot air leakage and functional interference caused by the cover 11c not being closed.

[0090] For example, see Figure 5 The main unit 20 is provided with a power supply contact 23 corresponding to the installation position of the drying module 10, and the drying module 10 is provided with an electrical receiving contact 17. The power supply contact 23 and the electrical receiving contact 17 adopt a concave-convex plug-in structure.

[0091] When the drying rack 30 moves upward a second predetermined distance under the control of the drying control module 21 and reaches the drying position, the drying module 10 rises synchronously with the drying rack 30. Its electrical receiving contact 17 abuts against the power supply contact 23 of the main unit 20 to achieve electrical connection, thereby supplying power to the hot air supply unit 16 of the drying module 10 through the main unit 20. Correspondingly, the drying control module 21 is also configured to: when it detects that the electrical receiving contact 17 and the power supply contact 23 have formed an electrical connection, and receives a drying command, respond to the drying command and control the drying module 10 to perform the drying action.

[0092] Establishing an effective electrical connection between the electrical receiving contact 17 and the power supply contact 23 is a necessary condition for initiating the drying operation, providing dual protection in conjunction with the lid 11c closure detection. Only when the drying control module 21 simultaneously detects that the electrical connection has been established, the lid 11c is closed, and a drying command has been received will it respond to the command and control the drying module 10 to execute the drying operation, ensuring coordination between power supply and drying. This avoids power supply during non-operational periods, saving energy and reducing safety hazards caused by accidental power supply activation.

[0093] The drying module 10 integrates a microcontroller 12 and an operation panel 19 with a built-in battery. The microcontroller 12 is directly electrically connected to the hot air supply unit 16 and the sterilization unit 18, and communicates with the main unit 20. When the drying rack 30 descends, causing the electrical receiving contact 17 to disconnect from the power supply contact 23 (offline state), the user can directly set parameters such as drying temperature, running time, and sterilization mode through the operation panel 19 without relying on the main unit 20 for power, thus improving the flexibility of use. The coupling structure between the electrical receiving contact 17 and the power supply contact 23 integrates a signal transmission channel in addition to the high-voltage power supply channel, which can also realize signal interaction between the microcontroller 12 and the main unit 20 of the drying rack. The user can send commands to the main unit 20 via remote control, which are transmitted to the microcontroller 12 through the signal channel, and the microcontroller controls the start / stop, power, and temperature control of the hot air supply unit 16, as well as the start / stop of the sterilization unit 18.

[0094] See Figure 2 This embodiment also proposes a clothes drying rack, including a main unit 20, a drying rack 30 that can be raised and lowered relative to the main unit 20, a drying module 10 disposed on the drying rack 30, and the aforementioned clothes drying device.

[0095] For example, a slot 31 is formed on one side (e.g., left or right) along the length of the main unit 20. The size of the slot 31 is adapted to the shape of the main body 11 of the drying module 10, and the slot 31 is arranged through the drying rack 30 in the lifting direction, without affecting the normal lifting stroke of the drying rack 30. The main body 11 of the drying module 10 is assembled in an embedded manner and is detachably assembled in the slot 31. The cover 11c is located on the side of the slot 31 facing the main unit 20, that is, on the top surface of the slot 31. Support bars or support plates can be provided between the inner wall of the slot 31 and the outer wall of the main body 11 to support and limit the drying device. In addition, a locking structure can also be provided between the inner wall of the slot 31 and the outer wall of the main body 11 to lock the connection between the two. The locking structure can be a spring piece cooperating with a slot or a screw for fastening.

[0096] This clothes rack retains the core function of drying clothes, while the detachable drying module 10 provides users with flexible and controllable drying options. Users can choose to install or remove the drying device according to weather conditions, clothing type (size), and actual drying needs, allowing for quick switching between usage scenarios. Furthermore, the device is compatible with the assembly structure of most existing clothes racks and the limited space of balconies, enhancing the product's adaptability and practical value.

[0097] This embodiment also proposes a drying method applied to a clothes rack. The clothes rack includes a main unit 20, a clothes rack 30 that can be raised and lowered relative to the main unit 20, and a drying module 10 disposed on the clothes rack 30. Exemplarily, the clothes rack can be one of the aforementioned types, and the specific drying method includes:

[0098] The drying control module 21 responds to the first clothes drying command and controls the drying rack 30 to descend a first predetermined distance to adapt to the hanging drying needs of the first item, allowing the user to hang the first item.

[0099] In response to the second clothes-drying command, the drying control module 21 controls the drying rack 30 to descend a second predetermined distance to accommodate the placement requirements of the second item, allowing the user to place the second item into the drying module 10; and in response to the drying command, the drying control module 21 controls the drying rack 30 to rise a second predetermined distance, controlling the drying module 10 to perform a drying action on the second item.

[0100] Prior to the step of controlling the drying rack 30 to rise a second predetermined distance in response to the drying command, the step of monitoring the status of the cover 11c is also included:

[0101] The opening and closing detection module 13 at the opening 11b end of the drying module 10 detects whether the cover 11c of the drying module 10 is in a closed state.

[0102] If the opening and closing detection module 13 indicates that the cover 11c is in a closed state, then the steps of raising the drying rack 30 a second predetermined distance and performing the drying action are executed.

[0103] If the opening and closing detection module 13 indicates that the cover 11c is not closed, the drying control module 21 will not respond to the drying command, the drying rack 30 will maintain the operating height corresponding to the current second predetermined distance, and the drying module 10 will not start and will remain in the closed state.

[0104] Before the step of controlling the drying module 10 to perform the drying action on the second item, an electrical connection status monitoring step is also included:

[0105] The system detects whether an electrical connection is formed between the drying module 10 and the main unit 20. This electrical connection is achieved by controlling the drying rack 30 to rise a second predetermined distance, causing the electrical receiving contact 17 of the drying module 10 to abut against the power supply contact 23 of the main unit 20. Only when an electrical connection is detected between the drying module 10 and the main unit 20, and the aforementioned cover 11c closure condition is met, will the subsequent steps of starting the drying module 10 and performing the drying action on the second item be executed. If no valid electrical connection is detected, the drying module 10 remains in the off state, and the drying action is not performed temporarily.

[0106] In one exemplary embodiment, the following control logic is further included during the process of controlling the drying module 10 to perform the drying action on the second item:

[0107] If the drying control module 21 receives a lifting control command, it controls the drying rack 30 to perform the corresponding lifting or lowering action, and simultaneously controls the hot air supply unit 16 to stop working.

[0108] Once the drying rack 30 has completed its lifting and lowering operation and returned to the drying position corresponding to the second predetermined distance, the drying control module 21 controls the drying module 10 to resume the drying action.

[0109] The high-priority design of the lifting control command allows the drying rack 30 to be raised and lowered at any time during the drying mode. This not only meets the user's need for immediate adjustment and can be operated without exiting the drying mode to avoid cumbersome procedures and improve ease of use, but also ensures operational safety through the linkage logic of synchronously pausing with the hot air supply unit 16. This achieves flexible and controllable drying process and meets the design requirements of practicality and reliability.

[0110] See Figures 1 to 5 ,as well as Figure 7 This embodiment also proposes a drying device for use with a clothes rack. The clothes rack includes a main unit 20, a clothes rack 30 that can be raised and lowered relative to the main unit 20, and a drying module 10 disposed on the clothes rack 30. The drying device includes a drying control module 22, which is configured to have the following two modes:

[0111] First drying mode: In response to the first drying command, control the drying rack to descend 30 degrees to hang the first item;

[0112] Second drying mode: In response to the second drying command, the drying rack 30 is controlled to descend to place the second item on the drying module 10, and in response to the drying command, the drying rack 30 is controlled to rise to a preset position and perform the drying action.

[0113] The drying command refers to the control command used to start the drying module 10 to perform the drying action. Its triggering methods include, but are not limited to: sending to the host 20 via remote control, sending remotely via mobile terminal APP, triggering via voice control, triggering via gesture recognition, or triggering directly through the drying module 10.

[0114] The first category of items refers to items suitable for regular natural air drying, conforming to the hanging design of the drying rack 30's drying area. These items are hung after the rack 30 is lowered to a suitable operating height to meet the needs of natural ventilation and sunlight drying, such as clothes, pants, and bed sheets. The second category of items refers to a type of item requiring specific drying treatment and conforming to the dedicated placement space of the drying module 10. These items are placed in a convenient operating position after the rack 30 is lowered to match the drying function's intended use, achieving efficient drying, such as underwear, socks, or handkerchiefs.

[0115] In this embodiment, the drying device integrates a drying control module 22 within the host unit 20. This module includes a processor and a memory. The memory stores the drying program, and the processor executes the program to implement related responses and control actions. The drying control module 22 responds to different drying commands. Specifically, it receives command signals through the host unit 20's communication module. Triggering methods include, but are not limited to, remote control sending, remote sending via a mobile terminal APP, voice control triggering, gesture recognition triggering, or sending via the drying module 10. The drying commands are generated either by the user's active operation based on the item's drying or air-drying needs, or automatically by the device according to preset logic. Specifically, these commands include a first drying command, a second drying command, and a drying command, driving the drying rack 30 to adjust its height accordingly. This adapts to the operational needs of different types of items, improving ease of use. Furthermore, the integration and height adjustment of the drying module 10 and the drying rack 30 enable the operation of both regular air-drying of the first item and drying of the second item, avoiding mutual interference while ensuring the effectiveness of drying energy and improving drying uniformity.

[0116] For example, in the first drying mode, the drying control module 22 is configured to control the drying rack 30 to descend a first predetermined distance; in the second drying mode, the drying control module 22 is configured to control the drying rack 30 to descend a second predetermined distance. The first predetermined distance is less than the second predetermined distance, so that the operating height of the drying rack 30 when it descends to the second predetermined distance is lower than the operating height when it descends to the first predetermined distance, thus adapting to the hanging requirements of the first item and the placement requirements of the second item, respectively.

[0117] For example, considering a typical ceiling height of about 2.8m, the first predetermined distance is typically set to 1.0m-1.2m, corresponding to the drying rack 30 being about 1.6m-1.8m above the ground after being lowered, which is suitable for the operation of hanging the first item; the second predetermined distance is set to 1.4m-1.6m, corresponding to the drying rack 30 being about 1.2m-1.4m above the ground after being lowered, which is suitable for placing the second item into the drying module 10, and also facilitates related operations by the user.

[0118] When in the first drying mode and the drying rack 30 has descended to the first predetermined distance, if a second drying command is received requiring a switch to the second drying mode, the drying control module 22 will control the drying rack 30 to descend by the difference between the second and first predetermined distances, stopping at the operating height corresponding to the second predetermined distance. This switching design eliminates the need for the drying rack 30 to reset and descend again, improving operational efficiency without affecting the hanging status of the first item. Similarly, when in the second drying mode and a switch to the first drying mode is required, the drying control module 22 will control the drying rack 30 to rise by the difference between the second and first predetermined distances, stopping at the operating height corresponding to the first predetermined distance.

[0119] To achieve zoned adaptation and independent operation of different types of items, the drying rack 30 is divided into a first drying area and a second drying area, and the drying module 10 is set in the second drying area.

[0120] In the first drying mode, when the drying rack 30 descends a first predetermined distance under the control of the drying control module 22, the first drying area is used to hang the first item;

[0121] In the second drying mode, when the drying rack 30 descends a second predetermined distance under the control of the drying control module 22, the second drying area is used to place the second item on the drying module 10.

[0122] For example, to optimize the overall spatial layout of the drying rack 30 and improve space utilization, the first drying area and the second drying area can adopt a design form of partial space coverage. This coverage is only an overlap in physical space and must meet the core premise of not affecting the normal use of the drying device: the covered area does not obstruct the installation and fixing structure of the drying module 10, does not hinder the opening and closing operation of the cover 11c of the drying module 10, and at the same time, it reserves operating space for the second item to be placed and the hot air circulation path when the drying module 10 is working, ensuring that the core functions of the second drying area for placing the second item and the drying module 10 performing the drying action are not interfered with in any way.

[0123] The drying module 10 is detachably mounted on the drying rack 30. The drying device also includes an on-site detection module 14 for detecting whether the drying module 10 is mounted on the drying rack 30. Exemplarily, the on-site detection module 14 includes a magnet and a Hall switch. The magnet is disposed in the second drying area corresponding to the installation position of the drying module 10, and the Hall switch is mounted on the drying module 10. When the drying module 10 is mounted in the second drying area of ​​the drying rack 30, the magnet aligns with the Hall switch and triggers an on-site detection signal, confirming that the drying module 10 is in a normal assembly state. If the drying module 10 is not mounted on the drying rack 30, the Hall switch does not detect the alignment signal of the magnet, and the drying module 10 cannot respond to drying-related operation commands, but this does not affect the normal use of other drying functions of the clothes rack.

[0124] For example, see Figure 3 The drying module 10 includes a main body 11, a cover 11c, and a hot air supply unit 16. The main body 11 has a cavity 11a for accommodating a second item. This cavity 11a has an opening 11b, and a storage structure 15 for supporting the second item is provided within the cavity 11a. This structure can be a grid-type or tiered shelf, etc. The cover 11c is closable at the opening 11b end of the cavity 11a, used to close or open the cavity 11a. When the cover 11c is closed, it creates a relatively sealed environment in the cavity 11a. The hot air supply unit 16 is mounted on the main body 11, with its air inlet connected to the outside atmosphere and its air outlet connected to the cavity 11a, used to deliver hot air into the cavity 11a to dry the second item.

[0125] In one exemplary embodiment, a sterilization unit 18 is also provided on the cover 11c of the drying device. The sterilization unit 18 is assembled on the side of the cover 11c facing the cavity 11a. It can be an ultraviolet sterilization lamp or other suitable sterilization structure. When the cover 11c is closed and the cavity 11a forms a relatively sealed environment, the sterilization unit 18 can be started synchronously with the hot air supply unit 16. Its effective range can cover the second item in the cavity 11a.

[0126] For example, see Figure 4The drying device also includes an opening / closing detection module 13, which is installed at the opening 11b end of the cavity 11a and is used to detect the opening / closing state of the cover 11c. For example, the opening / closing detection module 13 uses a microswitch, which is mounted at the opening 11b end of the cavity 11a. A trigger element 11d is provided on the cover 11c at a position corresponding to the installation position of the microswitch. When the cover 11c is closed, the trigger element 11d triggers the microswitch to output a closing signal and feeds it back to the drying control module 22. When the cover 11c is open, the trigger element 11d disengages from the microswitch, and the microswitch outputs an open signal to the drying control module 22.

[0127] Correspondingly, the drying control module 22 is also configured to: in the second drying mode, when a drying command is received, first confirm the opening and closing status of the cover 11c through the opening and closing detection module 13; if the opening and closing detection module 13 detects that the cover 11c is in a closed state, then respond to the drying command, control the drying rack 30 to rise to the preset drying position, and trigger the hot air supply unit 16 to perform the drying action; if the opening and closing detection module 13 detects that the cover 11c is in an open state, then regardless of whether a drying command is received, no drying-related operation will be responded to, the drying rack 30 will maintain the operating height corresponding to the second predetermined distance unchanged, and the hot air supply unit 16 will remain in a closed state.

[0128] For example, see Figure 5 The main unit 20 is provided with a power supply contact 23, and the drying module 10 is correspondingly provided with an electrical receiving contact 17; the power supply contact 23 and the electrical receiving contact 17 adopt a concave-convex plug-in structure. When the drying rack 30 moves upward a second predetermined distance under the control of the drying control module 22 and reaches the drying position, the drying module 10 rises synchronously with the drying rack 30, and its electrical receiving contact 17 abuts against the power supply contact 23 of the main unit 20 to achieve electrical connection, thereby supplying power to the hot air supply unit 16 of the drying module 10 through the main unit 20.

[0129] The drying control module 22 is configured to: in the second drying mode, when it detects that the electrical receiving contact 17 and the power supply contact 23 are in contact to achieve electrical connection, and a drying command is received, it responds to the drying command and controls the drying module 10 to perform the drying action.

[0130] Establishing an effective electrical connection between the electrical receiving contact 17 and the power supply contact 23 is a necessary condition for initiating the drying operation, providing dual protection in conjunction with the lid 11c closure detection. Only when the drying control module 22 simultaneously detects that the electrical connection has been established, the lid 11c is closed, and a drying command has been received will it respond to the command and control the drying module 10 to execute the drying operation, ensuring coordination between power supply and drying. This avoids power supply during non-operational periods, saving energy and reducing safety hazards caused by accidental power supply activation.

[0131] The drying module 10 integrates a microcontroller 12 and an operation panel 19 with a built-in rechargeable battery. The microcontroller 12 is directly electrically connected to the hot air supply unit 16 and the sterilization unit 18, and communicates with the main unit 20. When the drying rack 30 descends, causing the electrical receiving contact 17 to disconnect from the power supply contact 23 (offline state), the user can directly set parameters such as drying temperature, running time, and sterilization mode through the operation panel 19, without relying on the main unit 20 for power supply and control, thus improving the flexibility of use. The coupling structure between the electrical receiving contact 17 and the power supply contact 23 integrates a signal transmission channel in addition to the high-voltage power supply channel, enabling signal interaction between the microcontroller 12 and the main unit 20 of the drying rack. The user can send commands to the main unit 20 via remote control, which are transmitted to the microcontroller 12 through the signal channel, allowing the microcontroller to control the start / stop, power, and temperature control of the hot air supply unit 16, as well as the start / stop of the sterilization unit 18.

[0132] The present invention also proposes another embodiment of a drying device, which is applied to the same clothes rack as the drying device in the previous embodiment. The drying device in this embodiment is also equipped with a drying control module 22, which is configured to include:

[0133] In response to the first clothes-drying command, control the clothes rack 30 to rise or fall to a first height for hanging the first item;

[0134] In response to a second clothes-drying command, the clothes rack 30 is controlled to rise or fall to a second height for placing a second item on the drying module 10; and in response to a drying command, the clothes rack 30 is controlled to rise to a preset position and perform a drying action; wherein the second height is lower than the first height.

[0135] The drying control module 22, drying instructions, and clothes drying instructions (including the first clothes drying instruction and the second clothes drying instruction) are consistent with the corresponding technical features in the aforementioned drying device embodiments.

[0136] For example, the first height and second height correspond to the target position parameters of the drying rack 30, respectively, with the difference being the different perspectives. The first and second predetermined distances are defined with reference to the descent distance of the drying rack 30 relative to the host 20, while the first and second heights are defined with reference to the final ground clearance of the drying rack 30. That is, the first height corresponds to the ground clearance of the drying rack achieved by the first predetermined distance (e.g., 1.6m-1.8m), which is used to accommodate the hanging operation of the first item; the second height corresponds to the ground clearance of the drying rack achieved by the second predetermined distance (e.g., 1.2m-1.4m), which is used to accommodate the placement operation of the second item into the drying module 10.

[0137] Except for the different ways of expressing the target position parameters, the drying device in this embodiment is basically consistent with the aforementioned drying device embodiment in other technical details such as the structural composition of the drying module 10, the functional logic of each detection module, the power supply connection method, the configuration of the sterilization unit 18, and the control function of the operation panel 19.
