[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] The present invention provides a clothes dryer, aiming to solve the problem of low drying efficiency of clothes dryers in the prior art when drying private clothes. Figures 1 to 14The clothes dryer comprises: a clothes dryer drum 1, which rotates along its own central axis; a space divider 2, which is arranged in the clothes dryer drum 1 along the central axis and divides the clothes dryer drum 1 into a first clothes dryer chamber 11 and a second clothes dryer chamber 12; an air outlet assembly 3, which is arranged at one end of the axis along the central axis in the clothes dryer drum 1, and the air outlet assembly 3 is provided with a first air outlet 324 and a second air outlet 325 respectively connected to the first clothes dryer chamber 11 and the second clothes dryer chamber 12; a return air assembly 4, which is arranged at the other end of the clothes dryer drum 1 opposite to the air outlet assembly 3, and the return air assembly 4 is provided with a first return air outlet 424 and a second return air outlet 425 respectively connected to the first clothes dryer chamber 11 and the second clothes dryer chamber 12. The clothes dryer drum 1 is the core component of the clothes dryer. The interior of the clothes dryer drum 1 is used to place the clothes to be dried, and it is supported by the drum frame 13 to maintain the roundness of the drum. The clothes dryer drum 1 can rotate along its own central axis, and can be driven to rotate by a motor. The rotation scheme is a prior art and is not described here. As the dryer 1 rotates, the clothes roll with gravity, which can help evenly distribute the drying airflow and dry the clothes quickly and efficiently. The space divider 2 is used to divide the internal space of the dryer 1 into two independent drying chambers, that is, to separate the first drying chamber 11 and the second drying chamber 12. The function of this divider is to allow the internal space of the dryer to perform two different drying operations at the same time, such as drying different types of clothes at the same time, such as private clothes and ordinary clothes, or to perform efficient classification and drying according to the amount and fabric type of clothes. The air outlet component 3 is located at one end of the dryer 1. The air outlet component 3 is responsible for blowing the drying airflow into the dryer 1. The air outlet component 3 is provided with two first air outlets 324 and second air outlets 325 that are connected to the first drying chamber 11 and the second drying chamber 12 respectively. That is, hot air can enter different drying areas through different air outlets to ensure that the clothes in each area can be dried evenly. The return air component 4 is arranged at the other end of the dryer 1 to draw back the air inside the dryer 1. The return air assembly 4 is provided with two first return air ports 424 and second return air ports 426 respectively connected to the first drying chamber 11 and the second drying chamber 12. Through the return air ports, air can circulate in the drying drum 1, which helps to accelerate the drying process and improve the thermal efficiency of the dryer. Under the action of the two sets of air outlets and return air ports, the independent flow of the drying airflows in the two chambers can be controlled, so that the clothes in different areas can be dried independently. When in use, the user can adjust or remove the partition of the dryer as needed, and choose to use the two chambers at the same time or only use one chamber for drying. For example, for private clothes when drying, the user can choose to dry only the clothes in the second drying chamber 12, while ordinary clothes are placed in the first drying chamber 11. This partitioned drying design can effectively avoid cross-contamination between clothes and improve the drying efficiency. In addition, in actual use, the dryer will also be equipped with an intelligent temperature control system, which can adjust the temperature and wind speed according to the real-time data feedback from the humidity sensor to ensure that the drying time of the clothes in each area is balanced, thereby achieving energy-saving and efficient drying process.Through the scheme of the embodiment of the present invention, the dryer can dry different types of clothes simultaneously in the same cycle, greatly improving the drying efficiency. At the same time, it also meets the family's special needs for private clothes and avoids the traditional dryer from wasting time and energy due to drying private clothes and ordinary clothes separately.

[0041] Compared with the prior art, in the technical solution of the present invention, a space divider is provided in the drying drum 1 of the dryer to obtain two independent drying chambers, and then an air outlet and an air return outlet are respectively provided at both ends of the two drying chambers so that the clothes in the two drying chambers can be dried separately, thereby allowing the user to dry more private clothes at one time and improving the drying efficiency of the dryer.

[0042] In one embodiment, referring to Figures 1 to 4 The clothes dryer of the present invention further comprises a first fan, a second fan and a drying and dehumidifying module 71 circulation path, the circulation path is placed outside the clothes drying drum 1, the first air outlet 324 and the first return air outlet 424 are connected to the first fan and the drying and dehumidifying module 71 through the circulation path, and the second air outlet 325 and the second return air outlet 425 are connected to the second fan and the drying and dehumidifying module 71 through the circulation path. Figure 4 For example, Figure 4 The circulating fan 72 in the drying airflow circulation pipeline of the dryer body 81 shown in the figure can be the first fan or the second fan. The first fan or the second fan is respectively located inside the dryer, and is used to promote the flow of drying airflow, and help the hot drying airflow to circulate in the first drying chamber 11 and the second drying chamber 12 in the drying drum 1. The specific arrangement of the circulation pipelines of the first fan and the second fan is not described here. The first fan is mainly responsible for promoting the flow of drying airflow in the first drying chamber 11, and the second fan is mainly responsible for promoting the flow of drying airflow in the second drying chamber 12. The control program of the dryer can more accurately control the air flow rate of each chamber by controlling the two fans separately, thereby optimizing the drying effect. Figure 4The airflow in the drying airflow circulation pipeline circulates in a counterclockwise direction, and the drying and dehumidifying module 71 is arranged at the front end of the circulating fan 72 along the airflow circulation direction, and the front end of the drying and dehumidifying module 71 is the return air pipeline 74, and the rear end is the outlet air pipeline 75. The function of the drying and dehumidifying module 71 is to remove moisture from the airflow returned from the return air pipeline 74 and regulate the temperature of the drying airflow, so as to ensure that the moisture is discharged in time, thereby accelerating the drying process, and by controlling the temperature, ensuring that the limit of the clothes is not damaged while ensuring the drying efficiency. In the specific use process, the drying and dehumidifying module 71 includes components such as a heater, a condenser, and a dehumidifier. The circulating air path is a system for planning and guiding the air flow path in the dryer. In this embodiment, the circulating air path is externally placed outside the dryer 1, and is connected to the first air outlet 324, the first return air outlet 424, the second air outlet 325, the second return air outlet 425, the first fan, the second fan and the drying and dehumidifying module 71 through a pipeline. Through the circulating air path, the first air outlet, the first drying chamber 11, the first return air outlet 424, the drying and dehumidifying module 71 are connected to the first fan to form a circulating path, and the second air outlet, the second drying chamber 12, the second return air outlet 425, the drying and dehumidifying module 71 are connected to the first fan to form another circulating air path. Correspondingly, the two circulating air paths also include respective return air ducts 74 and air outlet ducts 75, and the specific arrangements are not repeated here. The dryer controls the air flow and dehumidification of the two drying chambers respectively through two independent air circulation loops, avoiding the mutual interference of hot air between different drying chambers, so that the clothes drying effect of each drying chamber is more uniform and efficient.

[0043] In one embodiment, referring to Figures 5 to 8 The air outlet assembly 3 includes an air outlet inner structure 32, and the air outlet inner structure 32 is provided with a first air outlet interlayer 326, a second air outlet interlayer 327 and a second air outlet duct 328. The second air outlet duct 328 is connected to the second air outlet 325 and the second air outlet interlayer 327. The first air outlet 324 is connected to the first air outlet interlayer 326, wherein the first air outlet interlayer 326 and the second air outlet interlayer 327 are used to input airflow to the air outlets connected to them. The first air outlet interlayer 326 and the second air outlet interlayer 327 are components of the airflow channel, and are respectively connected to the first air outlet 324 and the second air outlet 325 of the clothes drying drum 1, and are used to input airflow to their respective air outlets, wherein the second air outlet interlayer 327 and the second air outlet 325 are connected through the second air outlet duct 328. The air outlet assembly 3 includes an air outlet inner structure 32. The so-called air outlet inner structure 32 is the air outlet interlayer, which is used to separate the airflow through the structural component layer to ensure that the drying airflows of different circulation air paths are effectively distributed and flowed without interfering with each other, thereby improving the drying efficiency. Figures 5 to 8For example, the inner structure 32 of the air outlet is provided with a first air outlet guide plate 321, a second air outlet guide plate 322 and a third air outlet guide plate 323, and the first air outlet 324 and the second air outlet 325 are arranged on the first air outlet guide plate 321. Through the separation of the three guide plates, a first air outlet interlayer 326 is separated between the first air outlet guide plate 321 and the second air outlet guide plate 322, and a second air outlet interlayer 327 is separated between the second air outlet guide plate 322 and the third air outlet guide plate 323. The second air outlet duct 328 passes through the first air outlet guide plate 321 and the second air outlet guide plate 322 so that the second air outlet 325 and the second air outlet interlayer 327 are connected, completing the separation of the two drying gas circulation paths in the air outlet assembly 3. By providing the first air outlet interlayer 326 and the second air outlet interlayer 327, the clothes dryer can better separate the gas flow and ensure that the drying airflow can be distributed to different drying chambers as needed. The design of the second air outlet duct 328 optimizes the guiding effect of the airflow, so that the hot air can be accurately introduced from the second air outlet interlayer 327 to the second air outlet 325. The first air outlet interlayer 326 and the second air outlet interlayer 327 are arranged in the same air outlet inner structure 32 through three plate structures and the second air outlet duct 328. While the airflow inside each interlayer does not interfere with each other, the thickness of the air outlet inner structure 32 can be reduced, which is convenient for reducing the overall design size of the dryer and reducing the manufacturing cost of the air outlet inner structure 32.

[0044] Further, refer to Figures 5 to 10 The return air assembly 4 includes a first return air interlayer 426, a second return air interlayer 427 and a second return air duct 428, the second return air duct 428 is connected to the second return air port 425 and the second return air interlayer 427, the first return air port 424 is connected to the first return air interlayer 426, wherein the first return air interlayer 426 and the second return air interlayer 427 are used to transport airflow from the return air ports connected to each other. In the embodiment of the present invention, the inner structure 32 of the outlet assembly 3 and the inner structure 42 of the return air assembly 4 have the same structure. Figures 5 to 8For example, the outlet air inner structure 32 and the return air inner structure 42 are arranged in mirror image at both ends of the central axis of the clothes drying drum 1. Since the outlet air inner structure 32 and the return air inner structure 42 are circular flat structures, the outlet air inner structure 32 and the return air inner structure 42 have the same actual structure. The return air inner structure 42 is also provided with a first return air guide plate 421, a second return air guide plate 422 and a third return air guide plate 423, and a first return air port 424 and a second return air port 425 are provided on the first return air guide plate 421. The first return air guide plate 421, the second return air guide plate 422 and the third return air guide plate 423 are respectively provided with a first return air interlayer 426 and a second return air interlayer 427, and a second return air duct 428 connects the second return air interlayer 427 and the second return air port 425. The first return air interlayer 426 and the second return air interlayer 427 guide the airflow passing through the first clothes drying chamber 11 and the second clothes drying chamber 12 to the return air path, so as to be transported to the drying and dehumidifying module 71 to realize circulation.

[0045] In one embodiment, referring to Figures 5 to 10 The air outlet assembly 3 further includes an air outlet outer structure 33, which is arranged on the outer side of the air outlet inner structure 32 along the axial direction of the central axis. A first cavity 333 is provided on one side of the air outlet outer structure 33 close to the air outlet inner structure 32, which is concave outward along the axial direction of the central axis. The air outlet inner structure 32 is rotatably arranged in the first cavity 333 along the central axis. The air outlet outer structure 33 is located outside the air outlet inner structure 32 and is arranged on the outer side of the air outlet inner structure 32 along the axial direction of the central axis of the clothes dryer. A first cavity 333 is provided on one side of the air outlet outer structure 33 close to the air outlet inner structure 32, which is concave outward along the axial direction of the central axis. The air outlet inner structure 32 is arranged in the first cavity 333, and the air outlet outer structure 33 wraps the air outlet inner structure 32. The air outlet outer structure 33 supports the air outlet inner structure 32 and guides the airflow into the air outlet inner structure 32. In order to enable the air outlet inner structure 32 to rotate with the clothes drying drum 1 so as to keep the supply of drying airflow to the first clothes drying chamber 11 and the second clothes drying chamber 12 synchronous, the air outlet inner structure 32 is set to a circular flat shape. On the circular flat air outlet inner structure 32, the first air outlet guide plate 321, the second air outlet guide plate 322 and the third air outlet guide plate 323 are circular plates, and the center is connected by a structure penetrating through. At this time, the first air outlet interlayer 326 sandwiched between the first air outlet guide plate 321 and the second air outlet guide plate 322 is not blocked by a structure along the radial direction of the central axis. The shape of the first cavity 333 matches the air outlet inner structure 32, and the space of the first cavity 333 provides the necessary accommodation position, so that the air outlet inner structure 32 can rotate freely without interfering with other components.

[0046] In one embodiment, referring to Figures 5 to 10The air outlet outer structure 33 also includes a first air outlet duct 331 and a second air outlet duct 332. The first air outlet duct 331 is connected to the first air outlet interlayer 326, and the second air outlet duct 332 is connected to the second air outlet interlayer 327. The first air outlet duct 331 is used to transport the airflow blown out by the first fan, and the second air outlet duct 332 is used to transport the airflow blown out by the second fan. Since the first air outlet duct 331 and the second air outlet duct 332 are arranged in layers to match the first air outlet interlayer 326 and the second air outlet interlayer 327 on the air outlet outer structure 33, when the air outlet inner structure 32 rotates along the central axis, the first air outlet duct 331 and the second air outlet duct 332 arranged on the air outlet outer structure 33 can be directly connected to the first air outlet interlayer 326 and the second air outlet interlayer 327, so as to realize the uninterrupted supply of drying airflow.

[0047] In one embodiment, referring to Figures 5 to 11 The return air assembly 4 also includes a return air outer structure 43, which is arranged on the outer side of the return air inner structure 42 along the axial direction of the central axis. A second cavity 433 is provided on a side of the return air outer structure 43 close to the return air inner structure 42, which is recessed outward along the axial direction of the central axis. The return air inner structure 42 is rotatably arranged in the second cavity 433 along the central axis. Similar to the air outlet assembly 3, in order to enable the air outlet inner structure 32 to rotate with the clothes drying drum 1 so as to keep the supply of drying airflow to the first clothes drying chamber 11 and the second clothes drying chamber 12 synchronous, the return air inner structure 42 is set into a circular flat shape. The return air outer structure 43 is provided with a second cavity 433 for accommodating the return air inner structure 42. The shape of the second cavity 433 matches the return air inner structure 42. The space of the second cavity 433 provides the necessary accommodation position, so that the return air inner structure 42 can rotate freely without interfering with other components.

[0048] Furthermore, the return air outer structure 43 further includes a first return air duct 431 and a second return air duct 432, wherein the first return air duct 431 is connected to the first return air interlayer 426, and the second return air duct 432 is connected to the second return air interlayer 427, and the first return air duct 431 and the second return air duct 432 are used to return air flow to the drying and dehumidification module. The return air outer structure 43 is supported by the return air end frame 73 and is connected to the return air duct 74. Since the first return air duct 431 and the second return air duct 432 are layered and matched with the first return air interlayer 426 and the second return air interlayer 427 on the return air outer structure 43, when the return air inner structure 42 rotates along the central axis, the first return air duct 431 and the second return air duct 432 arranged on the return air outer structure 43 can be directly connected with the first return air interlayer 426 and the second return air interlayer 427, so as to realize uninterrupted supply of drying airflow to the drying and dehumidification module 71, and the rear end pipeline of the drying and dehumidification module 71 is connected to the circulation fan 72 to realize circulation.

[0049] Furthermore, since the air outlet outer structure 33 is close to the circulation fan 72, in order to reduce the resistance of the drying airflow blown out by the circulation fan 72, the connection between the first air outlet 331 and the second air outlet 332 is a circular structure, and a smooth airflow guiding structure is arranged in the first air outlet 331 and the second air outlet 332, so as to reduce wind resistance and wind noise. The return air outer structure 43 is arranged close to the dryer door 82. When the drying airflow passes through the clothes in the drying chamber, the airflow speed decreases. In order to facilitate the arrangement of the return air outer structure 43, the interface between the first return air duct 431 and the second return air duct 432 is arranged to be flat, specifically, a flat elliptical shape.

[0050] In one embodiment, referring to Figures 5 to 8 , the size of the first air outlet 324 and the first return air outlet 424 is larger than the second air outlet 325 and the second return air outlet 425. The size of the first air outlet 324 and the first return air outlet 424 is larger than the second air outlet 325 and the second return air outlet 425. Through the size difference, the types of clothes processed by the airflow of the first air outlet 324 and the return air outlet and the second air outlet 325 and the return air outlet may have different requirements. The large-sized first air outlet 324 and the return air outlet can ensure the efficient operation of the main air flow channel of the dryer and realize the efficient drying of conventional fabric clothes. The relatively small second air outlet 325 and the return air outlet may be used for drying clothes such as silk fabrics or other clothes with low fiber strength.

[0051] In one embodiment, referring to Figure 12 to Figure 14, the space divider 2 is detachably arranged in the clothes dryer 1. The air outlet assembly 3 also includes an air outlet baffle 31, and the air outlet baffle 31 is provided with a first D-shaped groove 311 near the center. The return air assembly 4 also includes a return air outlet baffle 41, and the return air outlet baffle 41 is provided with a second D-shaped groove 411 near the center. A main partition plate 21 and a secondary partition plate 22 are provided on the space divider 2, and the main partition plate 21 and the secondary partition plate 22 are connected. A rear interlocking protrusion 24 and a front interlocking protrusion 25 are provided at both ends of the main partition plate 21 along the central axis, wherein the rear interlocking protrusion 24 is detachably engaged in the first D-shaped groove 311, and the front interlocking protrusion 25 is detachably engaged in the second D-shaped groove 411. The secondary partition plate 22 can be folded and unfolded relative to the main partition plate 21 by hinges for easy storage. Through the detachable, foldable and storable space divider 2 of this embodiment, the drying drum 1 can switch between partition drying and conventional drying, which is convenient for users. In particular, in order to allow the drying gas to fully contact the dried clothes, a plurality of diffuser holes are evenly arranged on the air outlet shield 31. In order to prevent the debris in the dried clothes from falling into the return air port, a plurality of holes are evenly arranged on the return air port shield 41, so as to block the passage of debris as much as possible while the air flow passes. For the convenience of maintenance, the return air port shield 41 is detachably mounted on the return air end frame 73.

[0052] Furthermore, in order to further enhance the support strength of the space divider 2 on the air outlet shield 31 and the return air outlet shield 41, an annular groove 312 is also provided on the air outlet shield 31, and a first auxiliary protrusion 26 and a second auxiliary protrusion 27 are provided on the side of the main partition plate 21 and the auxiliary partition plate 22 close to the air outlet shield 31. When the space divider 2 is installed in the clothes dryer 1, the first auxiliary protrusion 26 and the second auxiliary protrusion 27 are embedded in the annular groove 312, so that the space divider 2 has more support points on the air outlet shield 31, and the installation is more stable. In addition, the first auxiliary protrusion 26 and the second auxiliary protrusion 27 can slide in the annular groove 312, which facilitates the folding, storage and alignment installation of the main partition plate 21 and the auxiliary partition plate 22.

[0053] In addition, the dryer of the embodiment of the present invention is also equipped with an intelligent temperature control system, which can adjust the temperature and wind speed according to the real-time data feedback from the humidity sensor to ensure that the drying time of the clothes in each drying chamber is balanced, thereby achieving energy-saving and efficient drying process.
