[0058] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0059] like Figures 1 to 6 As shown, the first embodiment of the present invention provides an air duct assembly, which includes an air duct housing 1, a mounting assembly and a heating element 4. The air duct housing 1 forms an air duct. The mounting assembly is arranged at the side of the air duct housing 1; the mounting assembly includes a first mounting assembly 2 and a second mounting assembly 3; the second mounting assembly 3 is provided with a mounting groove 31 connected to the air duct; at least part of the first mounting assembly 2 is movably arranged to move to a closed position in which at least part of the first mounting assembly 2 covers the notch 32 of the mounting groove 31 or to a evasive position in which at least part of the first mounting assembly 2 avoids the notch 32. The heating element 4 is detachably arranged on the air duct housing 1; when the heating element 4 is installed on the air duct housing 1, the heating element 4 abuts against at least part of the first mounting assembly 2 so that at least part of the first mounting assembly 2 is in the evasive position, and the heating portion of the heating element 4 is arranged in the mounting groove 31 and is arranged opposite to the air duct.

[0060] The air duct assembly provided by the first embodiment of the present invention is adopted, and the installation process of the heating element 4 is effectively simplified by the arrangement of the first mounting assembly 2 and the second mounting assembly 3. When installing or removing the heating element 4, the user does not need to perform complicated operations, and only needs to simply insert or pull out the heating element 4 into or out of the mounting groove 31. The first mounting assembly 2 can move to a evasive position according to the installation requirements of the heating element 4 to facilitate the installation of the heating element 4 or to a closed position to cover the notch 32 of the mounting groove 31 to close the air duct, thereby effectively realizing the rapid assembly of the heating element 4. When the heating element 4 is not installed, the first mounting assembly 2 can automatically move to a closed position to cover the notch 32 of the mounting groove 31, which not only prevents dust and foreign matter from entering the air duct, but also maintains the structural integrity and stability of the air duct assembly. When the heating element 4 is installed, the first mounting assembly 2 is in an evasive position, which ensures the smooth installation of the heating element 4. At the same time, due to the abutment between the heating element 4 and the first mounting assembly 2, the structural stability of the air duct assembly is further enhanced. The detachable design of the heating element 4 allows the user or maintenance personnel to easily replace the heating element 4 without disassembling the entire dryer. In addition, the heating element 4 is designed as a module that can be easily installed and disassembled, which can separate the wiring system of the heating element 4 from the wiring of the entire dryer, effectively reducing the problems of wire clamping, wire hanging, wire cutting and wire stretching during the use of the dryer. In addition, the heating part of the heating element 4 is directly arranged in the mounting groove 31, opposite to the air duct. This design ensures that the heat can be directly and efficiently transferred to the air in the air duct, thereby improving the drying efficiency. Compared with the traditional design, this layout reduces the loss of heat during the transfer process, making the operation of the dryer more energy-saving and efficient. Therefore, the air duct assembly provided by this embodiment can solve the technical problem that the heating element in the air duct assembly in the prior art is not easy to assemble quickly.

[0061] Specifically, the air duct assembly provided in this embodiment is applicable to a clothes dryer. Specifically, the air duct assembly is applicable to a folding clothes dryer.

[0062] Specifically, the heating element 4 provided in this embodiment is connected to the control mainboard 7 via a single wire. Thus, by using a single wire to connect the heating element 4 to the control mainboard 7, the present design simplifies the electrical connection of the heating element 4 and reduces the complexity of the internal wiring. This simplification not only makes the assembly process more convenient and reduces the possibility of wiring errors, but also reduces the problems of wire clamping, wire hanging, wire cutting, wire stretching, etc. that are easily caused by operations such as unfolding or folding during the use of the clothes dryer.

[0063] Specifically, when at least part of the first mounting component 2 is in the closed position, at least part of the first mounting component 2 is located above the notch 32, and at least part of the first mounting component 2 is overlapped or connected to the second mounting component 3 on one side close to the second mounting component 3. Such a structural arrangement ensures that after the heating element 4 is disassembled, the first mounting component 2 can be moved to the closed position, covering the notch 32 of the mounting groove 31, preventing dust and foreign matter from entering the air duct, and maintaining the airtightness, cleanliness and integrity of the internal components of the air duct. At the same time, the overlap or connection between the first mounting component 2 and the second mounting component 3 enhances the structural stability of the entire air duct assembly, making it easier for the air duct assembly to maintain good sealing and structural strength.

[0064] Specifically, the first mounting assembly 2 includes a first baffle 21 and a first elastic member 22, one side of the first elastic member 22 is connected to at least part of the air duct housing 1, and the other side is used to connect or overlap with the first baffle 21; the first baffle 21 forms at least part of the first mounting assembly 2, the first baffle 21 is arranged around the air duct housing 1, at least part of the first baffle 21 is arranged in contact with the outer wall of the air duct housing 1, and the side of the first baffle 21 close to the second mounting assembly 3 is used to overlap or connect with the second mounting assembly 3. With such a structural arrangement, an automatically adjustable closed system is formed by introducing the combination of the first baffle 21 and the first elastic member 22. The first elastic member 22 (such as a spring) ensures that the first baffle 21 is always in a closed position when no external force is applied, and at least part of the first baffle 21 is in contact with the outer wall of the air duct housing 1, ensuring the airtightness of the air duct in the closed position. The overlap or connection of the first baffle 21 with the second mounting assembly 3 not only realizes the rapid fixation of the heating element 4, but also ensures the structural stability and safety of the heating element 4 when it is installed.

[0065] Specifically, in order to facilitate the movement of the first baffle 21 and ensure the structural stability of the air duct assembly, a protrusion 12 is provided on the air duct shell 1. The protrusion 12 protrudes from the outer wall of the air duct shell 1. One side of the first elastic member 22 is connected to the protrusion 12, and the other side is used to connect or overlap with the first baffle 21.

[0066] Specifically, the first elastic member 22 is a spring structure. The use of a spring structure as the first elastic member 22 has good reset performance and durability. The elastic properties of the spring ensure that the first baffle 21 can be quickly reset to the closed position when there is no external operation, effectively avoiding contamination inside the air duct. In addition, the spring has a simple structure, low cost, easy installation and maintenance, and can withstand repeated stretching and compression, which prolongs the service life of the air duct assembly, while also ensuring the smoothness and safety of the installation and disassembly process of the heating element 4.

[0067] Specifically, a first guide portion 11 is provided on the outer wall of the air duct housing 1, and a second guide portion 211 is provided on the side of the first baffle plate 21 close to the air duct housing 1, which is mutually guided and cooperated with the first guide portion 11, and the first guide portion 11 and the second guide portion 211 are both extended along the extension direction of the air duct housing 1. With such a structural arrangement, by providing the first guide portion 11 and the second guide portion 211, accurate guidance and positioning of the first baffle plate 21 on the air duct housing 1 are achieved, ensuring the smoothness and stability of the first baffle plate 21 when moving to the closed position or the avoidance position. This guiding mechanism reduces the alignment error during the installation of the heating element 4, ensuring that the heating element 4 can be accurately installed in the predetermined position, and also improves the assembly quality and work efficiency of the entire air duct assembly.

[0068] Specifically, the first guide portion 11 is a guide protrusion, and the second guide portion 211 is a guide groove. In this way, the use of the guide protrusion and the guide groove provides more reliable mechanical positioning and guidance, and can maintain good matching accuracy even in a high temperature or humid environment, avoiding guide failure caused by thermal expansion or material deformation. This design not only simplifies the structure of the air duct assembly, but also reduces assembly errors, ensuring the stability of the installation of the heating element 4 and the smoothness of the air duct airflow.

[0069] Specifically, the first baffle 21 includes a first plate 2101, a second plate 2102 and a third plate 2103 connected in sequence, the first plate 2101 and the third plate 2103 are arranged opposite to each other, the end of the first plate 2101 away from the second plate 2102 is used to overlap or connect with the second mounting assembly 3, and the end of the third plate 2103 away from the second plate 2102 is used to overlap or connect with the second mounting assembly 3. With such a structural setting, the design of the first baffle 21 of the three-plate connection structure not only increases the rigidity and stability of the first baffle 21, but also further optimizes the structural balance of the air duct assembly by overlapping or connecting with the second mounting assembly 3 respectively, and prevents deformation or damage caused by uneven force on one side. At the same time, the three-plate design also facilitates the precision processing and assembly of the first baffle 21, thereby improving production efficiency and product quality.

[0070] Specifically, the first plate 2101, the second plate 2102 and the third plate 2103 are all arranged in close contact with the outer wall of the air duct housing 1, and the second guide portion 211 is arranged on the second plate 2102. In this way, the close contact between the first baffle plate 21 and the outer wall of the air duct housing 1 ensures the airtightness of the first baffle plate 21 when it is in the closed position. The second guide portion 211 is arranged on the second plate 2102, which further optimizes the guiding performance, and even when the shape or size of the air duct housing 1 changes slightly, a good guiding effect can be maintained, thereby improving the adaptability and stability of the first baffle plate 21.

[0071] Specifically, there are at least two first elastic members 22, and at least two first elastic members 22 are arranged at intervals along the outer edge of the air duct housing 1. With such a structural arrangement, by arranging at least two first elastic members 22, distributed at intervals at the outer edge of the air duct housing 1, it can be ensured that the first baffle 21 has uniform elastic support in different directions and positions, thereby improving the balance and reset speed of the first baffle 21 during movement. The design of multi-point elastic support ensures that the first baffle 21 can quickly and stably return to the closed position even when subjected to external forces in different directions, thereby enhancing the installation safety of the heating element 4 and the structural reliability of the entire air duct assembly.

[0072] In this embodiment, the heating element 4 includes a heating body and a retaining rib 41 which are connected to each other. The retaining rib 41 is located on one side of the heating body and protrudes from the heating body. The heating body is used to be arranged opposite to the air duct, and the retaining rib 41 is used to abut against the first baffle 21 for limiting position. With such a structural arrangement, by arranging the retaining rib 41 on the heating element 4 and forming a limiting fit with the first baffle 21, the heating element 4 is automatically positioned and fixed during the installation process. This design simplifies the installation steps of the heating element 4. When installing the heating element 4, the user only needs to align the heating element 4 with the installation position, and the retaining rib 41 will naturally abut against the first baffle 21 to put it in an avoidance position, and the heating element 4 can be inserted smoothly. In this way, not only the installation efficiency is improved, but also the risk of installation failure or damage caused by inaccurate alignment is reduced, and the stability and safety of the installation of the heating element 4 are enhanced.

[0073] Specifically, there are at least two retaining ribs 41, one of the at least two retaining ribs 41 is located on one side of the heating body, and the other is located on the other side of the heating body. One of the at least two retaining ribs 41 is used to abut against the first plate 2101 for limiting position, and the other of the at least two retaining ribs 41 is used to abut against the third plate 2103 for limiting position. In this way, at least two retaining ribs 41 are provided to form limiting cooperation with the two sides of the first baffle 21 (the first plate 2101 and the third plate 2103), respectively, so as to form multi-point positioning of the heating element 4 during installation, thereby improving the positioning accuracy and stability. This design makes the heating element 4 more balanced during installation and disassembly, reduces the situation of excessive force on one side, and thus reduces the risk of structural deformation or damage. At the same time, multi-point limiting also enhances the contact stability between the heating element 4 and the first baffle 21, ensures that there will be no displacement due to vibration or thermal expansion and contraction during use, and improves the reliability of the entire device.

[0074] In this embodiment, the second mounting assembly 3 includes a second baffle 33, a mounting member 34 and a second elastic member 35. The second baffle 33 forms a mounting groove 31. One side of the second elastic member 35 is located in the mounting groove 31 and connected to the second baffle 33, and the other side is connected to the mounting member 34. The side of the mounting member 34 away from the second baffle 33 is used to carry the heating element 4; the mounting member 34 is used to overlap or connect with at least part of the side of the first mounting assembly 2 close to the second mounting assembly 3. With such a structural arrangement, the second mounting assembly 3 provides a stable and retractable installation environment for the heating element 4 through the combination of the second baffle 33, the mounting member 34 and the second elastic member 35. This design allows the second elastic member 35 to be compressed when the heating element 4 is installed, so that the mounting member 34 can accurately carry the heating element 4, and at the same time, the mounting groove 31 surrounded by the second baffle 33 ensures the positioning and fixation of the heating element 4. When the heating element 4 is installed, the elastic force of the second elastic member 35 helps to buffer the vibration and displacement of the heating element 4 during the operation of the clothes dryer, thereby improving the working stability of the heating element 4 and the service life of the clothes dryer. In addition, the overlap or connection between the mounting member 34 and the first mounting assembly 2 further enhances the structural integrity of the entire air duct assembly, ensuring that the air duct assembly can be automatically closed after the heating element is removed to prevent foreign matter from entering.

[0075] Specifically, the second elastic member 35 is a spring structure. In this way, using a spring structure as the second elastic member 35 can provide stable and lasting elastic support, ensuring that the heating element 4 is smoothly and steadily installed and removed. The spring structure has good resilience and can maintain its original elastic properties even after long-term use. At the same time, the spring structure is simple, low-cost, and easy to maintain, which is suitable for mass production and long-term use of dryers, thereby improving the economy and reliability of the equipment.

[0076] Specifically, when at least part of the first mounting assembly 2 is in a closed position, at least part of the first mounting assembly 2 on one side close to the second mounting assembly 3 abuts against the mounting member 34. In this way, when the first mounting assembly 2 is in a closed position, its abutment against the mounting member 34 ensures the structural integrity of the air duct assembly when the heating element 4 is not installed. This design prevents outside air or foreign matter from entering the air duct from the notch 32 of the mounting groove 31, maintains the clean and dry conditions inside the air duct, helps to improve the thermal efficiency of the dryer and prevent electrical failures. At the same time, the abutment effect also strengthens the physical connection between the first mounting assembly 2 and the second mounting assembly 3, and improves the structural stability and safety performance of the entire air duct assembly.

[0077] Specifically, when at least part of the first mounting assembly 2 is in the closed position, the first baffle 21 is in contact with the mounting member 34 on one side close to the second mounting assembly 3. In this way, the airtightness and structural stability of the air duct assembly are further enhanced when the first mounting assembly 2 is in the closed position.

[0078] Specifically, when at least part of the first mounting assembly 2 is in the closed position, one end of the first plate 2101 away from the second plate 2102 and one end of the third plate 2103 away from the second plate 2102 are both in contact with the mounting member 34. In this way, the first plate 2101 and the third plate 2103 are in contact with both sides of the mounting member 34, forming a more stable closed structure, thereby improving the sealing and mechanical strength of the entire air duct assembly. At the same time, the double-sided contact also reduces the risk of deformation or damage of the single-sided baffle due to external force, thereby enhancing the durability and reliability of the air duct assembly.

[0079] Specifically, the side of the heating element 4 is provided with a first fixing portion 42, and the side of the second baffle 33 is provided with a second fixing portion 331, and the first fixing portion 42 and the second fixing portion 331 are detachably connected. With such a structural arrangement, the detachable connection mechanism of the first fixing portion 42 and the second fixing portion 331 provides great convenience for the installation and removal of the heating element 4. This design allows the user or maintenance personnel to quickly install or remove the heating element 4 without tools, greatly saving operation time and maintenance costs. At the same time, the cooperation between the detachable first fixing portion 42 and the second fixing portion 331 also facilitates the cleaning and replacement of the heating element 4, improving the maintenance efficiency and user experience of the dryer. In addition, the connection between the first fixing portion 42 and the second fixing portion 331 ensures the stability of the heating element 4 during installation, reduces the displacement or damage of the heating element 4 caused by vibration or impact, and ensures the safe operation and stable performance of the dryer.

[0080] Specifically, the first fixing portion 42 is an annular member, and the second fixing portion 331 is a protruding member, and the annular member and the protruding member are arranged in a matching manner. In this way, the coordinated use of the annular member and the protruding member provides a simple and effective way to fix the heating element 4. This design ensures the accuracy and stability of the installation of the heating element 4, and prevents reduced thermal efficiency or safety problems caused by misalignment during the installation process. The matching connection between the annular member and the protruding member also simplifies the installation steps of the heating element 4. The user can easily align the annular member on the heating element 4 with the protruding member, and quickly fix it through the annular member without the need for additional tools or complicated operations, thereby improving the user's operating convenience and the maintenance efficiency of the dryer.

[0081] Specifically, the second baffle 33 is a U-shaped structure, the mounting member 34 is a plate-shaped structure, and the mounting member 34 is arranged to match the size of the mounting slot 31. The U-shaped structure can better surround the heating element 4, providing all-round support and positioning, while the mounting member 34 with a plate-shaped structure and a matching size ensures the vertical positioning of the heating element 4 in the mounting slot 31, avoiding shaking or displacement of the heating element 4 during operation, and improving the heat conduction efficiency and safety of the dryer.

[0082] Specifically, there are at least two second elastic members 35, and the at least two second elastic members 35 are arranged at intervals along the extension direction of the mounting member 34. This design provides a uniform and stable supporting force, ensuring smooth and safe installation and removal of the heating element 4. At the same time, this design can also provide additional buffering and shock absorption effects after the heating element 4 is installed, thereby enhancing the stability and durability of the dryer in a vibrating or moving environment.

[0083] In this embodiment, the air duct assembly further includes an alarm, a position detection member and a control member. The alarm is arranged on the air duct housing 1; the alarm is used to issue an alarm indication, the position detection member is arranged on the mounting member 34, and the position detection member is used to detect whether the heating element 4 is at a predetermined position of the mounting member 34. The alarm and the position detection member are both connected to the control member to control the alarm to issue an alarm indication according to the detection result of the position detection member. With such a structural setting, the alarm, the position detection member and the control member are introduced to form an intelligent monitoring system for detecting whether the heating element 4 is correctly installed in the predetermined position. This design improves the safety performance of the dryer and prevents electrical failures or fire risks caused by improper installation or non-installation of the heating element 4. The real-time monitoring of the position detection member and the timely feedback mechanism of the alarm can remind the user of the installation status of the heating element 4 and avoid potential safety hazards. The connection with the control member also enables the dryer to automatically adjust the operating mode according to the installation status of the heating element 4, such as automatically disabling the heating function when it is detected that the heating element is not installed, further ensuring the safety and reliability of the dryer during use.

[0084] like Figures 7 to 9 As shown, the second embodiment of the present invention provides a clothes dryer, and the clothes dryer includes the air duct assembly provided in the first embodiment.

[0085] The clothes dryer provided by the second embodiment of the present invention effectively simplifies the installation process of the heating element 4 through the arrangement of the first mounting assembly 2 and the second mounting assembly 3. When installing or removing the heating element 4, the user does not need to perform complicated operations, and only needs to simply insert or pull out the heating element 4 into or out of the mounting groove 31. The first mounting assembly 2 can move to the avoidance position according to the installation requirements of the heating element 4 to facilitate the installation of the heating element 4 or move to the closed position to cover the notch 32 of the mounting groove 31 to close the air duct, effectively realizing the rapid assembly of the heating element 4. When the heating element 4 is not installed, the first mounting assembly 2 can automatically move to the closed position to cover the notch 32 of the mounting groove 31, which not only prevents dust and foreign matter from entering the air duct, but also maintains the structural integrity and stability of the air duct assembly. When the heating element 4 is installed, the first mounting assembly 2 is in the avoidance position, ensuring the smooth installation of the heating element. At the same time, due to the abutment between the heating element 4 and the first mounting assembly 2, the structural stability of the air duct assembly is further enhanced. The detachable design of the heating element 4 allows users or maintenance personnel to easily replace the heating element 4 without disassembling the entire clothes dryer. Moreover, the heating element 4 is designed as a module that can be easily installed and disassembled, so that the wiring system of the heating element 4 can be separated from the wiring of the whole dryer, effectively reducing the problems of wire clamping, wire hanging, wire cutting and wire stretching during the use of the dryer. In addition, the heating part of the heating element 4 is directly arranged in the mounting groove 31, opposite to the air duct. This design ensures that the heat can be directly and efficiently transferred to the air in the air duct, thereby improving the drying efficiency. Compared with the traditional design, this layout reduces the loss of heat during the transfer process, making the operation of the dryer more energy-saving and efficient. Therefore, the dryer provided by this embodiment can solve the technical problem that the heating element in the air duct assembly in the prior art is not easy to assemble quickly.

[0086] Specifically, the clothes dryer is a folding clothes dryer.

[0087] Specifically, the clothes dryer further comprises a housing 5, the housing 5 having an assembly space and an assembly port 51 communicating with the assembly space, the air duct assembly is arranged in the assembly space, and the assembly port 51 is arranged opposite to the second mounting assembly 3 of the air duct assembly. The clothes dryer further comprises a cover 6, which is movably arranged at the assembly port 51 to move to a closed position where the cover 6 covers the assembly port 51 or an open position where the cover 6 avoids the assembly port 51. With such a structural arrangement, the combined design of the housing 5 and the cover 6 provides an operable environment that is both easy to operate and can ensure the safety of the equipment. The movable arrangement of the cover 6 allows the user to easily open and close the assembly port 51 to perform the installation and removal operations of the heating element 4, thereby improving the maintainability and user-friendliness of the clothes dryer. When the cover 6 moves to the closed position, it is tightly covered on the assembly port 51 to prevent dust and foreign matter from entering the air duct assembly, thereby maintaining the clean state of the internal air duct, and helping to improve the drying efficiency and equipment life. In addition, the closing function of the cover body 6 also provides additional protection for the dryer during transportation or storage, thereby preventing the air duct assembly from being damaged due to external impact.

[0088] Specifically, there are at least two shell parts 5, one of the at least two shell parts 5 is connected to the other and is rotatably arranged along a preset rotation axis, so as to move to a folded position where one of the at least two shell parts 5 is relatively arranged or an unfolded position where one of the at least two shell parts 5 is arranged at a preset angle, and the preset angle is greater than 90 degrees and less than or equal to 180 degrees; there are at least two air duct components, and at least two air duct components and at least two shell parts 5 are arranged one by one. In this way, the design of at least two shell parts 5, combined with the rotatable arrangement according to the preset rotation axis, realizes the folding function of the dryer, significantly reduces the volume of the equipment, facilitates storage and movement, improves space utilization efficiency, and is particularly suitable for small households or environments that often need to be moved. The adjustment range of the preset angle (greater than 90 degrees and less than or equal to 180 degrees) enables the two shell parts 5 to form a sufficiently large working space when the dryer is in the unfolded position to meet the drying needs of clothes of different sizes. At the same time, when in the folded position, the two shell parts 5 fit closely, reducing the occupied space. The one-to-one arrangement of the air duct assembly and the housing portion 5 ensures that each air duct assembly can work independently and efficiently, thereby improving the overall drying capacity and thermal energy utilization rate of the dryer. In addition, this also facilitates the user to flexibly select and configure the number of heating elements 4 according to the type and needs of clothing in actual application, thereby realizing personalized setting of heating power.

[0089] Specifically, the corresponding heating elements 4 of at least two air duct components are electrically connected to the control mainboard 7 through wires. By centrally and electrically connecting all the heating elements 4 to the control mainboard 7, centralized control and management of the heating elements 4 inside the clothes dryer is achieved. The control mainboard 7 can accurately adjust the working state of each heating element 4, such as opening, closing, power adjustment, etc., according to the preset drying program or user settings, which helps to optimize the heat energy distribution during the drying process, improve the drying efficiency, and reduce energy consumption.

[0090] Specifically, the clothes dryer also includes a wiring terminal, which is used to be inserted into the wiring port of the heating element 4 of the air duct assembly to energize the heating element 4; a plug-in slot 52 is provided on the shell portion 5, and the plug-in slot 52 is located on one side of the air duct assembly, and the plug-in slot 52 is used to insert the wiring terminal. With such a structural setting, by providing the plug-in slot 52 on the shell portion 5, in conjunction with the wiring terminal, when the heating element 4 is removed, the wiring terminal used for electrical connection with the heating element 4 can be accommodated in the plug-in slot 52, which is convenient for the arrangement of the wiring, and also convenient for the rapid wiring of the heating element 4 after installation, ensuring the stability and safety of the subsequent electrical connection, and avoiding electrical failures or safety hazards caused by improper wiring. This design is also convenient for the replacement and maintenance of the heating element 4. The user can easily unplug the wiring terminal to clean or replace the heating element 4 without disassembling the entire clothes dryer, thereby improving the maintenance efficiency and maintainability of the equipment.

[0091] Specifically, the working principle of the clothes dryer includes: when the heating element 4 needs to be used normally, the other door of the middle shell (equivalent to the cover body 6) needs to be opened, and then in the process of installing the heating element 4 downward, the user needs to first push the first baffle 21 backward. The first baffle 21 is composed of three side panels, and its function is to close the upper, left and right sides of the air duct. The rear of the first baffle 21 is a fixed structure composed of a spring and a protrusion 12, and the spring is tightly connected to the protrusion 12. In the process of pushing the first baffle 21 backward, the first baffle 21 pushes the spring, and the spring will shrink backward. When the first baffle 21 is pushed out to a distance equivalent to the width of the heating element 4, the heating element 4 can be installed downward. The second baffle 33 at the bottom of the air duct is composed of a mounting groove 31 and a second elastic member 35. The two ends of the second elastic member 35 are fixedly connected to the second baffle 33 and the mounting member 34 respectively. When the heating element 4 applies pressure downward, the second elastic member 35 will shrink, and the mounting member 34 will shrink into the mounting groove 31. At this time, the door buckle (equivalent to the first fixing part 42) and the buckle column (equivalent to the second fixing part 331) at both ends of the bottom of the heating element 4 can be used to fix the bottom of the heating element 4, and the retaining ribs 41 on both sides of the heating element 4 will push the first baffle 21 and fix it. When the heating element 4 is removed, the spring on the rear side of the first baffle 21 will return to its original state and push the first baffle 21 forward under the action of the elastic force. In order to ensure that the moving track of the first baffle 21 does not deviate, a slideway (equivalent to the first guide part 11) is designed on the upper side of the air duct housing 1. In this way, after the first baffle 21 moves forward, the air duct can be sealed on the upper, left and right sides. At the same time, the second baffle 33 is also extended from the mounting groove 31 driven by the elastic force to achieve the sealing of the bottom surface of the air duct. Through this telescopic device of the baffle and the spring, when the heating element 4 is removed, the air duct can be automatically sealed, which not only improves convenience but also maintains stability.

[0092] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: through the modular design of the heating element, the user no longer needs complicated internal wiring processing when installing or removing the heating element, which greatly simplifies the operation process, reduces the difficulty of installation, and improves maintenance efficiency. Especially for non-professional users, this design significantly improves the user-friendliness of the equipment; in this solution, there is no need to worry about the damage of the internal circuit when installing and removing the heating element, so that the wiring system of the heating element is separated from the wiring of the whole machine, which simplifies the wiring system of the heating element and reduces the electrical faults and safety hazards caused by clamping, hanging, cutting, etc. during the opening and closing process of the folding dryer; users can customize the drying power according to the type of clothing, and by controlling the operation of different numbers of heating elements and reasonably allocating heat energy, not only the drying efficiency is improved, but also the efficient use of energy is achieved. This flexible power adjustment mechanism meets the drying needs of different clothes and avoids energy waste.
