[0035] In order to solve the problem of poor drying effect of the existing drying machine, the present application provides a drying machine and a drying machine control method.

[0036] As shown in Figures 1 to 5 The drying machine includes an air duct structure 10 and an inner drum assembly 20. The air duct structure 10 has an air outlet 11, an air passing space and an air return port 12, and the air outlet 11 and the air return port 12 are both in communication with the air passing space. The inner drum assembly 20 includes an inner drum structure 21 and an air passing structure 22 sleeved outside the inner drum structure 21, and the air passing structure 22 rotates synchronously with the inner drum structure 21; an air passing cavity 23 is formed around the outer surface of the air passing structure 22 and the air passing space, and the air passing structure 22 has a plurality of air passing holes 221, which are arranged in the circumferential and / or axial direction of the inner drum structure 21, and each air passing hole 221 is in communication with the air passing cavity 23. Among them, the air outlet 11 is located below the inner drum assembly 20, and the air return port 12 is located above the inner drum assembly 20.

[0037] By applying the technical scheme of the present embodiment, the air outlet 11 is located below the inner drum assembly 20 and can directly provide hot air to the clothes, and the air return port 12 is located above the inner drum assembly 20, so that the air flowing in the inner drum structure 21 during the drying process is "downward and upward", which ensures that the clothes in the inner drum structure 21 maintain a suspended drying state, on the one hand, reduces the entanglement between the clothes, the accumulation of the clothes in the inner drum structure 21 and the friction between the clothes and the inner drum structure 21, increases the contact area between the hot air and the clothes, effectively reduces the wear of the clothes during the drying process, and prolongs the service life of the clothes; on the other hand, the optimized air flow design increases the heat and moisture exchange area between the air and the clothes, ensures uniform distribution of the incoming air and the return air, avoids local overheating or incomplete drying, so that heat and moisture can be more effectively taken away, significantly improves the drying efficiency and speeds up the drying speed, thereby improving the uniformity and quality of the drying, and solving the problem of poor drying effect of the existing drying machine. At the same time, a plurality of air passing holes 221 in communication with the air passing cavity 23 are distributed on the air passing structure 22, the gas discharged from the air outlet 11 enters the inner drum structure 21 through a part of the air passing holes 221, and the gas after completing the drying in the inner drum structure 21 is discharged to the air return port 12 through another part of the air passing holes 221, realizing the recycling of the gas, thereby saving energy consumption, and realizing the efficient, energy-saving and environmentally friendly drying process.

[0038] As shown in Figure 2 The clothes dryer further comprises a partition structure 30 arranged in the air duct structure 10 and outside the inner drum assembly 20 to divide the air passing cavity 23 into a first chamber 231 and a second chamber 232 arranged in the height direction. The plurality of air passing holes 221 comprises a first air passing hole group and a second air passing hole group. The first air passing hole group is located in the second chamber 232, and the air outlet 11 communicates with the first air passing hole group through the second chamber 232. The second air passing hole group is located in the first chamber 231, and the air return inlet 12 communicates with the second air passing hole group through the first chamber 231. In this way, by arranging the partition structure 30 in the air duct structure 10, the air passing cavity 23 is effectively divided into two independent air flow channels, i.e. the first chamber 231 and the second chamber 232 in the height direction, and the plurality of air passing holes 221 on the air passing structure 22 are divided into the first air passing hole group and the second air passing hole group. The first air passing hole group is located in the second chamber 232 and directly communicates with the air outlet 11, and the second air passing hole group is located in the first chamber 231 and directly communicates with the air return inlet 12, thereby achieving the purpose of fine adjustment of air flow distribution and enhancing the efficiency of heat and moisture exchange. It is ensured that the first chamber 231 is a return air area and the second chamber 232 is a supply air area, thereby avoiding the short circuit of the supply air directly entering the air return inlet 12 from the air outlet 11, so as to ensure that the air flow discharged from the air outlet 11 can first enter the inner drum structure 21 through the first air passing hole group and then be discharged to the air return inlet 12 through the second air passing hole group to realize air return.

[0039] In the present embodiment, the first air passing hole group receives hot air directly from the air outlet 11, which can form a strong hot air flow at the bottom area of the clothes, effectively pushing the materials to float upwards to achieve the suspended state of the clothes. The second air passing hole group is used to guide the wet and hot air after drying to be discharged through the air return inlet 12, avoiding the accumulation of wet and hot air at the top area of the clothes and reducing the risk of direct short circuit of the wet and hot air at the upper part of the drum. In this way, through the above-mentioned layered air flow path optimization, uniform heating and efficient drying of the clothes in the drum are realized, and the technical effect of reducing the residual moisture in the clothes is achieved, thereby solving the technical problems of uneven drying and energy waste caused by insufficient hot air at the bottom of the clothes and accumulation of wet and hot air at the top in the traditional clothes dryer.

[0040] Optionally, the volume of the first chamber 231 is less than or equal to the volume of the second chamber 232. In this way, since the first chamber 231 is mainly used for the input of hot air, and the second chamber 232 is mainly used for the capture and discharge of humid hot air, the above arrangement ensures efficient use of hot air and effective management of humid hot air, reduces unnecessary energy loss, and thus reduces the overall energy consumption of the clothes dryer. At the same time, by optimizing the airflow distribution of the air duct structure and the inner drum assembly, the clothes dryer can complete the drying of the clothes in a shorter time, while reducing the wear and tear of the clothes, improving the drying efficiency and the level of clothes protection, and enhancing the user's experience.

[0041] In the present embodiment, the air passing structure 22 is a cylindrical structure, and the central axis of the cylindrical structure is coaxially arranged with the central axis of the inner drum structure 21. The inner drum assembly 20 further comprises a connecting structure, and the inner drum structure 21 is fixedly connected with the cylindrical structure through the connecting structure. The connecting structure is located within the orthographic projection of the partition structure 30 on the inner drum assembly 20. In this way, the connecting structure is within the orthographic projection area of the partition structure 30, and does not interfere with the airflow distribution of the first chamber 231 and the second chamber 232, ensuring that the hot air and the humid hot air can smoothly pass through the chambers allocated respectively, avoiding airflow short circuit, and enhancing the controllability of the airflow and the drying efficiency. At the same time, the cylindrical air passing structure can uniformly distribute the hot air, in combination with the distribution of the first air passing hole group and the second air passing hole group, so that the clothes at different heights can receive hot air, and at the same time, the humid hot air can be uniformly captured and discharged, thereby improving the efficiency of heat and moisture exchange and the drying effect of the clothes.

[0042] As shown in Figures 1 to 4 The air duct structure 10 comprises a first pipe body 13, an air duct cover 14, and a second pipe body 15. The air duct cover 14 has a first through hole, an air passing space, and a second through hole. The first pipe body 13 is arranged in the first through hole to form an air outlet 11 at the communication part of the air duct cover 14. The second pipe body 15 is arranged in the second through hole to form an air return inlet 12 at the communication part of the air duct cover 14. The air duct cover 14 is slidably connected with the air passing structure 22. In this way, the first pipe body 13 and the second pipe body 15 are independently arranged, so that the hot air and the humid hot air can enter and exit the air duct cover through their respective channels, avoiding mutual interference between the airflows, achieving accurate control of the hot air and the humid hot air, reducing energy waste, and improving the drying efficiency. At the same time, during the synchronous rotation of the air passing structure 22 with the inner drum structure 21, the air duct cover 14 is fixed, and the slidably connected air duct cover 14 and air passing structure 22 can reduce the friction therebetween, improve the running stability of the clothes dryer, and prolong the service life of the clothes dryer.

[0043] As shown in Figure 4As shown, the clothes dryer further comprises a matching assembly 40, which comprises a first matching part 41 and a second matching part 42. The first matching part 41 is arranged on the air duct cover 14, and the second matching part 42 is arranged on the air passing structure 22. One of the first matching part 41 and the second matching part 42 is a protrusion, and the other is a recess, and the protrusion extends into the recess to limit the matching. In this way, by arranging the first matching part 41 on the air duct cover 14 and the second matching part 42 on the air passing structure 22, one of which is a protrusion and the other is a corresponding recess, the limit matching of the protrusion and the recess is achieved, which improves the control accuracy of the airflow and ensures the stable operation of the system. At the same time, the limit matching design of the first matching part 41 and the second matching part 42 can accurately control the relative position between the air duct cover 14 and the air passing structure 22, so that stable and accurate airflow transmission between the air duct structure 10 and the inner drum assembly 20 can be ensured even in a high-speed running environment, and airflow organization confusion and efficiency decline caused by relative displacement of the two are avoided.

[0044] In the embodiment, the first matching part 41 is a protrusion, and the second matching part 42 is a recess, and the protrusion extends into the recess to limit the matching.

[0045] As shown in the drawings, Figure 4 The clothes dryer further comprises a sealing structure 50 arranged between the first matching part 41 and the second matching part 42. The sealing structure 50 is made of rubber or silicone. In this way, the sealing structure 50 can effectively seal the gap between the first matching part 41 and the second matching part 42, prevent the leakage of airflow at the matching position of the protrusion and the recess, ensure that the hot air and the humid air can only enter and exit the air duct cover 14 through the predetermined air outlet 11 and the air return port 12, avoid unnecessary energy loss, and improve the energy utilization efficiency. At the same time, the good sealing performance ensures the integrity of the airflow path, reduces the unnecessary dissipation of hot air and the premature loss of humid air, makes the heat and moisture exchange process more efficient, not only speeds up the drying speed of the clothes, but also reduces the overall energy consumption of the clothes dryer, which meets the energy-saving and environmental protection trend of modern household appliances.

[0046] Optionally, the recess is a groove, and the sealing structure 50 is two, and the two sealing structures 50 are respectively matched with the two groove walls of the groove.

[0047] Optionally, the sealing structure 50 is a sealing ring.

[0048] As shown in the drawings, Figure 4As shown, the air duct cover 14 includes a cylinder body 141 and two oppositely arranged annular plates 142. The cylinder body 141 is sleeved outside the inner cylinder assembly 20 and has a first through hole and a second through hole, and the central axis of the cylinder body 141 is coaxially arranged with the central axis of the inner cylinder structure 21. The two oppositely arranged annular plates 142 are located inside the cylinder body 141, and a through air space is formed around the two annular plates 142 and the cylinder body 141; the central axis of each annular plate 142 is coaxially arranged with the central axis of the cylinder body 141. Among them, the outer ring surface of each annular plate 142 is connected with the cylinder body 141, and the first matching part 41 is arranged on the inner ring surface of each annular plate 142. In this way, the through air space formed by the air duct cover 14 and the two annular plates 142 can more finely control the airflow path entering and leaving the inner cylinder assembly 20, ensure that the hot air and the humid air exchange heat and humidity in their respective preset chambers, and improve the uniformity of the airflow and the efficiency of the heat and humidity exchange. At the same time, the first matching part 41 on the annular plate 142 and the second matching part 42 of the through air structure 22 form a dynamic limiting fit, which can keep the accurate alignment between the air duct cover and the through air structure even in the environment of high-speed operation of the clothes dryer, avoiding the airflow organization confusion caused by relative motion, and enhancing the stability and reliability of the system.

[0049] In the present embodiment, the accurate design of the coaxially arranged cylinder body 141 and inner cylinder structure 21 and annular plate 142 together ensures efficient transmission of airflow between the air duct cover 14 and the inner cylinder assembly 20, reduces energy loss during transmission, realizes full utilization of energy, and reduces the operating energy consumption of the clothes dryer.

[0050] As shown in the drawings, Figure 1 The separation structure 30 includes two partitions 31, each of which extends along the axial direction of the inner cylinder assembly 20, and the side edge of each partition 31 has a first edge, a second edge, a third edge and a fourth edge connected in sequence, the first edge is connected with the cylinder body 141, the second edge and the fourth edge are respectively connected with each annular plate 142, and the third edge has a preset gap with the through air structure 22. In this way, the space inside the air duct cover 14 is divided into a first chamber 231 and a second chamber 232 by the two partitions 31, and each chamber has an independent airflow inlet and outlet path, thereby ensuring that the airflow entering the inner cylinder structure 21 and the airflow leaving the inner cylinder structure 21 will not directly mix, avoiding the occurrence of airflow short circuit phenomenon, and improving the efficiency of heat and humidity exchange. At the same time, the preset gap between the third edge of the partition 31 and the through air structure 22 prevents the through air structure 22 from interfering with the third edge during synchronous rotation with the inner cylinder structure 21, thereby affecting the normal operation of the inner cylinder assembly 20.

[0051] In the embodiment, the clothes dryer further comprises a cabinet 60 and a fan, the cabinet 60 has a first air passage, a mounting cavity and a second air passage, the first air passage communicates with the second air passage through the mounting cavity. The fan is arranged in the mounting cavity. The first air passage communicates with the air outlet 11, and the second air passage communicates with the air return port 12. In this way, the first air passage in the cabinet communicates with the air outlet 11, and the second air passage communicates with the air return port 12, and a gas circulation system is formed through the driving of the fan, thereby ensuring that the hot air can be effectively recycled after fully contacting the clothes, and the humid hot air is sent into the inner drum again after the cooling and dehumidification and heating processes, thereby improving the efficiency of the gas circulation and the energy utilization of the drying process. At the same time, the accurate placement of the fan and the effective communication with the air outlet 11 and the air return port 12 can accurately control the inlet and outlet amount and the wind speed of the gas flow, avoid the energy waste caused by excessive air volume, and also reduce the problem of prolonging the drying time caused by insufficient air volume, thereby realizing the efficient management of energy.

[0052] Optionally, the clothes dryer further comprises a driving device, a detection device and a control module. The driving device is drivingly connected with the inner drum assembly 20 to drive the inner drum assembly 20 to rotate, and the detection device is arranged in the inner drum structure 21 to detect the weight of the clothes located in the inner drum structure 21. The control module is electrically connected with the driving device, the fan and the detection device. The control module controls the working parameters of the driving device and / or the rotating speed of the fan according to the weight detection value of the detection device. In this way, the control module can adjust the working parameters of the driving device (such as the motor), for example, adjust the rotating speed or the torque, according to the weight information of the clothes fed back by the detection device, so as to ensure that the inner drum assembly 20 can rotate at the optimal speed under various conditions, thereby promoting the uniform suspension of the clothes in the drum and accelerating the drying process. At the same time, by adjusting the rotating speed of the fan, the control unit can ensure the appropriate intensity of the gas flow, avoid damaging the clothes due to excessive wind force, or reduce the low drying efficiency caused by insufficient wind force.

[0053] In the embodiment, the intelligent control based on the weight of the clothes can accurately match the required energy input, thereby avoiding excessive energy consumption or energy waste, especially when a small amount of clothes is processed, the energy consumption can be significantly reduced, and the goal of energy saving and emission reduction is achieved. At the same time, the control module optimizes the gas dynamics by analyzing the weight data of the clothes, so that the hot air can more uniformly penetrate the clothes pile, the adhesion and coverage between the clothes are reduced, the heat and moisture exchange efficiency is improved, and the overall drying time is shortened.

[0054] The application also provides a clothes dryer control method suitable for the clothes dryer.

[0055] The weight value of the clothes in the inner drum structure 21 of the clothes dryer is acquired in real time, and the rotating speed of the inner drum assembly 20 and / or the rotating speed of the fan is adjusted according to the weight value of the clothes.

[0056] Specifically, according to the weight of the clothes, the rotation speed of the inner drum assembly 20 is dynamically adjusted, which can promote the suspension state of the clothes in the drum, increase the contact area of the clothes and the hot air, optimize the heat and moisture exchange process, and thus significantly improve the drying efficiency and the uniformity of the clothes drying. At the same time, through the weight information of the clothes obtained by the detection device, the control module can intelligently judge and adjust the rotation speed of the fan, so as to avoid using unnecessary high air volume when processing light load clothes, or insufficient air volume when heavy load, effectively reducing energy consumption, and realizing the goal of energy saving and environmental protection.

[0057] In this embodiment, according to the weight of the clothes, the rotation speed of the inner drum assembly 20 is adjusted, which can avoid excessive tumbling when there are fewer clothes, reduce the friction and collision between the clothes, reduce the risk of wear and tear of the clothes, protect the original appearance and material of the clothes, and prolong the service life of the clothes. At the same time, by monitoring the weight of the clothes in real time and making targeted adjustments, the clothes dryer can adapt to the drying needs of different loads, avoiding the inconvenience or errors of manual adjustment, simplifying the operation process, and improving the user's experience.

[0058] In this embodiment, the method for adjusting the rotation speed of the inner drum assembly 20 and / or the rotation speed of the fan according to the weight value of the clothes includes:

[0059] If the weight value of the clothes is greater than or equal to G2, the fan is controlled to rotate at a rotation speed V3, and the inner drum assembly 20 is controlled to rotate at a rotation speed V 33 ;

[0060] If the weight value of the clothes is greater than or equal to G1 and less than G2, the fan is controlled to rotate at a rotation speed V2, and the inner drum assembly 20 is controlled to rotate at a rotation speed V 22 ;

[0061] If the weight value of the clothes is less than G1, the fan is controlled to rotate at a rotation speed V1, and the inner drum assembly 20 is controlled to rotate at a rotation speed V 11 ; wherein V3≥V2≥V1, V 33 ≥V 22 ≥V 11 .

[0062] Specifically, according to the different weight values of the clothes, the rotation speeds of the fan and the inner drum assembly are automatically adjusted, avoiding the waste of energy caused by fixed high rotation speed. When processing lighter clothes, the fan rotates at a lower speed V1, and the inner drum assembly 20 rotates at a lower speed V 11 , reducing unnecessary energy consumption; for heavier clothes, the fan rotates at a higher speed V3, and the inner drum assembly 20 rotates at a higher speed V 33 , thereby ensuring sufficient heat and moisture exchange, and realizing effective use of energy. At the same time, by dynamically adjusting the rotation speed, especially V3≥V2≥V1 and V 33 ≥V 22 ≥V11 Under these conditions, it ensures more thorough contact between hot air and clothing, optimizes the heat and moisture exchange process, significantly improves the drying speed and quality of clothing, and shortens the drying cycle.

[0063] In this embodiment, adjusting the rotation speed of the inner drum assembly according to the weight of the clothing can reduce the chance of clothing excessively tumbling or colliding inside the drum, especially when handling lightly loaded clothing. 11 The low rotation speed reduces wear and tear on clothing, protects the fabric, and extends the garment's lifespan. Meanwhile, the automated, tiered control strategy simplifies operation; users don't need to manually adjust equipment parameters. The equipment automatically selects the optimal operating mode based on the weight of the clothing, improving ease of use and user satisfaction.

[0064] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0065] The air outlet is located below the inner drum assembly and can directly supply hot air to the clothes, while the return air outlet is located above the inner drum assembly 20. This allows for a "bottom-in, top-out" airflow within the inner drum structure during the drying process, ensuring that the clothes remain suspended and dried. This reduces tangling between clothes, accumulation of clothes within the inner drum structure, and friction between clothes and the inner drum structure, increasing the contact area between hot air and clothes. This effectively reduces wear and tear on clothes during the drying process and extends their lifespan. Furthermore, the optimized airflow design increases the heat and moisture exchange area between air and clothes, ensuring even distribution of air intake and return, avoiding localized overheating or incomplete drying. This allows heat and moisture to be carried away more effectively, significantly improving drying efficiency and speed, thereby enhancing the uniformity and quality of drying. This solves the problem of poor drying performance in existing dryers. Meanwhile, the air passage structure has multiple air passage holes that communicate with the air passage cavity. The gas discharged from the air outlet enters the inner cylinder structure through some of the air passage holes. After drying in the inner cylinder structure, the gas is discharged to the return air port through another part of the air passage holes, realizing gas recovery and reuse, thereby saving energy consumption and achieving a high-efficiency, energy-saving and environmentally friendly drying process.
