Drying mechanism of clothes drying machine and clothes drying machine

Abstract

The application discloses a drying mechanism of a clothes airing machine, which comprises a blowing pipeline, a pipeline main body of the blowing pipeline extending along the length direction of the clothes airing machine, and a bottom plate of the pipeline main body being provided with air outlet holes arranged along the length direction of the clothes airing machine; one side of the pipeline main body is provided with an air inlet connecting port; a fan is connected to the air inlet connecting port and used for conveying a drying airflow into the blowing pipeline; wherein the blowing pipeline further comprises a flow regulation plate arranged in the pipeline main body along the air outlet holes, the flow regulation plate is located at the side of the air outlet holes away from the air inlet connecting port, and the drying airflow is guided downwards to the air outlet holes by the flow regulation plate. When the fan sends in the horizontal drying airflow from the side, the airflow is guided by the flow regulation plate after colliding with the flow regulation plate, and is directly turned to be sent out vertically downwards from the air outlet holes. Compared with the traditional structure in which the airflow needs to collide with the wall and turn back for many times (such as colliding with the pipeline side wall after horizontal flowing and then reversely flowing), the design only needs to turn once, greatly reduces the vortex loss, and realizes the provision of more sufficient air volume.

Description

Technical Field

[0001] This application relates to the technical field of clothes drying racks, and more particularly to a drying mechanism for a clothes drying rack and a clothes drying rack. Background Technology

[0002] Current electric clothes drying racks mainly consist of a main unit and a clothes rack that can be raised and suspended below the main unit. Some high-end models also integrate a drying function. Specifically, this drying function is achieved by setting up a drying system inside the main unit. Its working principle is to use the drying system to blow hot air downwards, thereby accelerating the evaporation of moisture from the clothes hanging on the rack and achieving the purpose of rapid drying.

[0003] Most drying systems on the market currently employ a cross-flow fan paired with a narrow air delivery channel. The air delivery channel runs parallel to the length of the lower drying rod, with evenly distributed air outlets at the bottom. Driven by the fan, hot air is delivered to the drying rod area through the air delivery channel. However, this existing structure has a significant technical flaw: because the fan is typically connected to the side of the air delivery channel, the hot air flows primarily horizontally within the channel, perpendicular to the orientation of the air outlets at the bottom. This design results in substantial air resistance loss along the path of the hot air from the fan outlet to the air outlets, leading to a significant reduction in the volume of hot air delivered from the outlets. Furthermore, the air pressure cannot meet the requirements for efficient drying, ultimately affecting the drying efficiency and uniformity of the clothes, and increasing drying energy consumption. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a drying mechanism for a clothes drying machine and a clothes drying machine, which can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On the one hand, a drying mechanism for a clothes dryer is provided, comprising: An air supply duct includes a duct body extending along the length of the clothes drying rack, and an air outlet is provided on the bottom plate of the duct body along the length of the clothes drying rack; an air inlet is provided on one side of the duct body. A fan is connected to the air inlet to deliver drying airflow into the air supply duct. The air supply duct also includes a rectifier plate disposed inside the duct body along the air outlet. The rectifier plate is located on the side of the air outlet facing away from the air inlet. The rectifier plate guides the drying airflow downward to the air outlet for delivery.

[0006] Optionally, the rectifier plate is provided with a first ventilation notch corresponding to the air inlet connection port, and a second ventilation notch is reserved at the end of the rectifier plate and the end of the duct body. A bypass channel is formed between the side of the rectifier plate facing away from the air outlet and the duct body. Part of the drying airflow can be transported to the end area of ​​the duct body through the bypass channel and sent out from the air outlet near the end area.

[0007] Optionally, along the length of the air supply duct, the width ratio of the first ventilation gap to the second ventilation gap is 1:(2~3).

[0008] Optionally, the two ends of the duct body are a first end and a second end, respectively, and the air inlet is located near the first end; the rectifier plate includes a first rectifier plate and a second rectifier plate located on both sides of the first ventilation gap, the first rectifier plate extending towards the first end and the second rectifier plate extending towards the second end; The bypass channel is formed between the second rectifier plate and the main body of the pipe. The first rectifier plate is connected to a guide plate on the side near the first ventilation gap, and the drying airflow is guided to the bypass channel through the guide plate.

[0009] Optionally, one end of the air guide plate is connected to the first rectifier plate, and the other end extends obliquely toward the bypass channel and is connected to the side wall of the duct body opposite to the second rectifier plate.

[0010] Optionally, the air inlet is tilted toward the second end.

[0011] Optionally, a flow divider is provided inside the main body of the pipe between the air inlet and the air outlet. The flow divider divides the drying airflow sent in from the air inlet, so that part of the airflow flows toward the area where the first rectifier plate is located and part of the airflow flows toward the area where the second rectifier plate is located.

[0012] Optionally, the end of the diverter plate near the air outlet points towards the first ventilation gap.

[0013] Optionally, the flow area of ​​the first ventilation gap is 10% to 20% of the flow area of ​​the air inlet connection.

[0014] Optionally, the air outlet is configured to include a first air outlet and a second air outlet arranged alternately along the length of the main body of the pipe. The first air outlet is used to guide the drying airflow vertically downward, and the second air outlet is used to guide the airflow obliquely downward and outward.

[0015] Optionally, the length ratio of the first air outlet to the length of the second air outlet is 1.5:1 to 3:1.

[0016] Optionally, the fan includes a volute and an impeller located inside the volute. The volute has a capacity-enhancing protrusion on the side facing away from the air supply duct, which increases the internal volume of the volute. The outer wall of the capacity-enhancing protrusion has a clearance groove for avoiding the steel wire rope of the clothes drying rack.

[0017] On the other hand, a clothes drying rack is provided, including the aforementioned drying mechanism.

[0018] The beneficial effects of this application are as follows: This utility model provides a drying mechanism for a clothes dryer. By setting a rectifier plate opposite to the air inlet on the side of the air outlet, when the fan sends in the horizontal drying airflow from the side, the airflow hits the rectifier plate and is guided by it, directly turning vertically downward and being sent out from the air outlet. Compared with the traditional structure where the airflow needs to hit the wall and turn back multiple times (such as hitting the side wall of the pipe after flowing horizontally and then flowing in the opposite direction), this design only needs to turn once, which greatly reduces eddy current loss, provides more sufficient air volume, and ensures that the stable and sufficient air volume enhances the ability of hot air to penetrate clothing fibers and accelerates moisture evaporation.

Detailed Implementation

[0022] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] Current electric clothes drying racks mainly consist of a main unit and a clothes rack that can be raised and suspended below the main unit. Some high-end models also integrate a drying function. Specifically, this drying function is achieved by setting up a drying system inside the main unit. Its working principle is to use the drying system to blow hot air downwards, thereby accelerating the evaporation of moisture from the clothes hanging on the rack and achieving the purpose of rapid drying.

[0026] Most drying systems on the market currently employ a cross-flow fan paired with a narrow air delivery channel. The air delivery channel runs horizontally along the length of the lower drying rack, with air outlets evenly distributed at the bottom. Driven by the fan, hot air is transported to the drying rack area through the air delivery channel. However, this existing structure has a significant technical flaw: because the fan is typically connected to the side of the air delivery channel, the hot air flows primarily horizontally within the channel, perpendicular to the orientation of the air outlets at the bottom. This design results in substantial air resistance loss along the path of the hot air from the fan outlet to the air outlets. Specifically: When horizontally flowing hot air needs to be turned by hitting the pipe wall of the air supply duct multiple times before entering the air outlet, the whole process requires multiple sharp changes in direction, which generates local eddy current losses. The narrow air supply channel itself will generate resistance along the airflow, and the uneven airflow distribution in the channel caused by the side air supply of the fan will further increase the wind resistance. Increased wind resistance directly leads to a significant reduction in the volume of hot air delivered from the air outlet, and the air pressure also fails to meet the requirements for efficient drying, ultimately affecting the drying efficiency and uniformity of clothes.

[0027] To overcome the above technical defects, embodiments of this application provide a drying mechanism for a clothes drying rack, comprising: The air supply duct 1 includes a duct body 11 extending along the length of the clothes drying machine, and an air outlet 14 arranged along the length of the clothes drying machine is provided on the bottom plate of the duct body 11; an air inlet 16 is provided on one side of the duct body 11. Fan 2 is connected to the air inlet 16 to deliver drying airflow into the air supply duct 1; The air supply duct 1 also includes a rectifier plate 12 disposed within the duct body 11 along the air outlet 14. The rectifier plate 12 is located on the side of the air outlet 14 facing away from the air inlet connection 16. The rectifier plate 12 guides the drying airflow downward to the air outlet 14 for discharge. The fan 2 is connected to the side of the air supply duct 1. When the fan 2 is started, it delivers horizontally flowing drying airflow into the air supply duct 1. When the drying airflow hits the rectifier plate 12, it turns downward and is directly discharged through the air outlet 14. In this process, the drying airflow only undergoes one turn, which obviously results in less wind resistance compared to the traditional method that requires multiple turns, and less airflow and air pressure loss in the downward-output drying airflow.

[0028] In summary, in this embodiment, by setting a rectifier plate 12 opposite to the air inlet 16 on the side of the air outlet 14, when the fan 2 sends in horizontal drying airflow from the side, the airflow impacts the rectifier plate 12 and is guided by it, directly turning vertically downwards and being sent out from the air outlet 14. Compared to the traditional structure where the airflow needs to hit the wall and turn back multiple times (such as flowing horizontally and then hitting the side wall of the pipe before flowing in the opposite direction), this design only requires one turn, greatly reducing eddy current loss, providing more sufficient airflow, and ensuring a stable and sufficient airflow to improve the ability of hot air to penetrate clothing fibers and accelerate moisture evaporation.

[0029] In one embodiment, the rectifier plate 12 is provided with a first ventilation notch 171 corresponding to the air inlet connection port 16, and a second ventilation notch 172 is reserved at the end of the rectifier plate 12 and the end of the pipe body 11. A bypass channel 17 is formed between the side of the rectifier plate 12 facing away from the air outlet 14 and the pipe body 11. Part of the drying airflow can be transported to the end area of ​​the pipe body 11 through the bypass channel 17 and sent out from the air outlet 14 near the end area.

[0030] Considering that the air supply duct 1 is a long and narrow channel with a relatively long distance between its end and the air inlet 16, the air volume will gradually decrease as the airflow is transported through a single channel. This will eventually result in the air volume at the air outlet 14 near the end of the air supply duct 1 being significantly less than that near the air inlet 16. In this solution, the rectifier plate 12 is spaced apart from the inner wall of the duct body 11 to create an independent bypass channel 17. The two ends of the bypass channel 17 are connected to the corresponding channels of the air outlet 14 through the first ventilation gap 171 and the second ventilation gap 172, respectively. During the air supply process, part of the drying airflow entering through the air inlet 16 will enter the bypass channel 17 through the first ventilation gap 171 and be directly transported to the end of the air supply duct 1 (there is no air outlet 14 at the bottom of the bypass channel 17). Then, it will be deflected and supplemented to the area near the air outlet 14 through the second ventilation gap 172 at the end, so that the air outlet 14 near the end also has sufficient air volume. This improves the uniformity of airflow along the entire length of the air duct 1, making the drying rate of clothes in different parts more consistent and reducing energy waste.

[0031] In addition, a bypass channel 17 is equipped with an airflow compensation mechanism. Part of the airflow enters the bypass channel 17 through the first ventilation gap 171 and is transported to the end without loss along the length of the pipe. Then, it is deflected by the second ventilation gap 172 and supplemented to the end air outlet 14 area. This process forms an airflow circulation of "near-end diversion - far-end supplementation". This allows the airflow of the bypass channel 17 to supplement the air outlet 14 at the far end of the pipe, balancing the airflow attenuation caused by friction resistance. This improves the uniformity of the airflow at the air outlet 14, enhances the synchronicity of drying clothes hanging in different locations, and avoids the need to extend the overall drying time due to slow drying of some clothes, thereby reducing drying energy consumption.

[0032] In specific settings, an electric heater 5 can be installed at the air inlet 16 of the main pipe body 11, or at the air outlet of the fan 2, so that the airflow entering the main pipe body 11 is heated and the drying rate is optimized.

[0033] Regarding the main body of the pipeline 11, refer to... Figure 5 Optionally, it can be configured as an upper shell and base structure with upper and lower covers connected, and the top surface of the entire base is open. This facilitates the forming of air outlet 14, rectifier plate 12 or other structures inside the base. When necessary, the interior can also be cleaned by disassembling the upper shell.

[0034] In one embodiment, along the length of the air supply duct 1, the width ratio of the first ventilation gap 171 to the second ventilation gap 172 is 1:(2~3).

[0035] At the second ventilation gap 172 located at the end, the airflow needs to form a 180° deflection. Setting the width of the second ventilation gap 172 to two to three times that of the first ventilation gap 172 can ensure that the airflow in the bypass channel has enough space to deflect and turn, reduce pressure loss, and ensure that there is enough airflow to supplement the end of the air supply duct 1.

[0036] In one embodiment, reference is made to Figure 5 and Figure 6 The two ends of the main body of the pipe 11 are a first end 111 and a second end 112, respectively, and the air inlet connection 16 is located near the first end 111; the rectifier plate 12 includes a first rectifier plate 121 and a second rectifier plate 122 located on both sides of the first ventilation gap 171, the first rectifier plate 121 extends toward the first end 111, and the second rectifier plate 122 extends toward the second end 112; The bypass channel 17 is formed between the second rectifier plate 122 and the pipe body 11. The first rectifier plate 121 is connected to a guide plate 13 on the side near the first ventilation gap 171, and the drying airflow is guided to the bypass channel 17 through the guide plate 13.

[0037] Combination Figure 2 The air inlet 16 is located near the first end 111. The overall structure connecting the air supply duct 1 and the fan 2 is L-shaped, with one end larger than the other (the area near the first end 111, which is closer to the air inlet, has a larger space, while the space at the second end 112 gradually decreases). This allows for a centrally symmetrical arrangement of two drying mechanisms within the main unit 10. Each of the two drying mechanisms corresponds to two parallel drying rods below, which deliver the drying airflow. This centrally symmetrical arrangement of the two drying mechanisms makes fuller use of the internal space of the main unit 10, improving the overall compactness of the main unit 10.

[0038] Based on this, since the first end 111 is closer to the air inlet 16, the drying airflow only needs to pass through a short path to reach the air outlet 14 near the first end 111. The airflow loss is small in this process, so there is no need to supplement the airflow. In contrast, the second end 112 is farther from the air inlet 16. Therefore, the bypass channel 17 is set on the side of the second rectifier plate 122. With the guidance of the air guide plate 13, the drying airflow entering through the first ventilation gap 171 can be transported to the more distant second end 112 and deflected to supplement the air outlet 14 in the area near the second end 112.

[0039] In one embodiment, reference is made to Figure 7One end of the air guide plate 13 is connected to the first rectifier plate 121, and the other end extends obliquely toward the bypass channel 17 and is connected to the side wall of the pipe body 11 opposite to the second rectifier plate 122.

[0040] One end of the air guide plate 13 is fixedly connected to the side of the first rectifier plate 121 near the first ventilation opening 171 (the connection position is located on the side of the first rectifier plate 121 facing the air inlet connection 16); the other end extends obliquely towards the bypass channel 17 and is finally fixedly connected to the side wall of the duct body 11 opposite to the second rectifier plate 122 (i.e., the side wall of the bypass channel 17 away from the second rectifier plate 122). This design makes the air guide plate 13 form a "guide ramp" that slopes from the first rectifier plate 121 towards the side wall of the duct, so as to guide the airflow more smoothly and gently into the bypass channel 17, reduce the wind resistance in this process, and ensure air volume and air pressure.

[0041] In one embodiment, the air inlet 16 is tilted toward the second end 112.

[0042] The axis of the air inlet 16 is inclined toward the second end 112 (far end) of the pipe body 11, forming an angle of 15° to 60° with the length direction of the pipe. Specifically, the opening direction of the air inlet 16 is away from the first end 111 (near end) and points toward the second end 112 (far end), so that the drying airflow sent by the fan 2 cuts into the pipe body 11 at an inclined angle. After the air outlet of the fan 2 is connected to the inclined air inlet 16, the initial direction of the airflow is at an angle with the length direction of the pipe and extends directly to the far end, rather than the traditional vertical side air intake or inclined to the near end.

[0043] The inclined air intake directs the initial airflow direction toward the second end 112, forming a far-end priority delivery logic: after the airflow enters the pipeline, the main energy rushes toward the far end along the inclined direction, reducing the loss along the way in long-distance delivery.

[0044] In one embodiment, reference is made to Figure 6 and Figure 8 The main body of the pipe 11 is provided with a diverter plate 15 located between the air inlet connection 16 and the air outlet 14. The diverter plate 15 diverts the drying airflow sent in by the air inlet connection 16, so that part of the airflow flows toward the area where the first rectifier plate 121 is located, and part of the airflow flows toward the area where the second rectifier plate 122 is located.

[0045] One end of the diverter plate 15 is fixed to the inner wall of the duct body 11 near the air inlet 16, and the other end extends into the duct, dividing the initial area of ​​the airflow sent into the air inlet 16 into two independent flow channels. This allows the airflow to be diverted by the diverter plate 15, with one part flowing towards the first end 111 where the first rectifier plate 121 is located, and the other part flowing towards the second end 112 where the second rectifier plate 122 is located. The diverter plate 15 typically adopts a straight or slightly curved design. Guided by the diverter plate 15, part of the drying airflow flows along a short path to the first end 111 area, is turned by the first rectifier plate 121, and is then sent out from the near-end air outlet 14 (without the need for supplementary air from the bypass channel 17). The other part of the drying airflow, guided by the diverter plate 15, flows to the second end 112 area, with one part directly turned by the second rectifier plate 122 and sent out from the corresponding air outlet 14, and the other part entering the bypass channel 17 through the first ventilation gap 171, ultimately supplementing the far-end air outlet 14.

[0046] This design avoids the disordered diffusion of airflow in the intake area when there is no splitter plate in the traditional 15, so that the airflow energy is distributed according to the near end demand and the far end demand, reducing the energy waste caused by eddies.

[0047] In one embodiment, the end of the diverter plate 15 near the air outlet 14 points towards the first ventilation gap 171.

[0048] In this structure, the edge of the splitter plate 15 is offset from the first rectifier plate 121, avoiding the formation of a sealed dead angle. Part of the airflow located near the first end 111 of the splitter plate 15 can directly enter the first ventilation gap 171 through the opening between the splitter plate 15 and the first rectifier plate 121, avoiding the problem of the airflow being blocked at this point and forming vortices that ultimately lose power, thus reducing energy waste overall.

[0049] In one embodiment, the flow area of ​​the first ventilation gap 171 is 10% to 20% of the flow area of ​​the air inlet connection 16.

[0050] With this ratio, most of the airflow (80%~90%) passes directly through the main channel, is turned by the rectifier plate 12, and is sent out through the air outlet 14 to ensure the basic air volume in the near and middle sections; a small portion of the airflow (10%~20%) enters the bypass channel 17 through the first ventilation gap 171 to supplement the air volume at the far end (second end 112).

[0051] In this embodiment, the air volume of the air outlet 14 at each location can be balanced along the entire length direction, so that the air outlet is uniform at each location.

[0052] In one embodiment, the air outlet 14 is configured to include a first air outlet 141 and a second air outlet 142 arranged alternately along the length direction of the pipe body 11. The first air outlet 141 is used to guide the drying airflow vertically downward, and the second air outlet 142 is used to guide the airflow obliquely downward and outward.

[0053] Specifically, the first air outlet 141 is a straight hole design, with the hole axis perpendicular to the bottom plate of the pipe, forming a vertically downward air supply direction; the second air outlet 142 is an oblique hole design, with the hole axis forming an angle of 15°~45° with the bottom plate of the pipe, and the oblique direction is towards the outside of the main body of the pipe 11 (away from the center of the clothes drying machine), forming an obliquely downward and outward air supply direction.

[0054] The first air outlet 141 blows air vertically downwards, directly affecting the clothing area directly below the outlet. It uses vertical air pressure to penetrate the clothing fibers, accelerating moisture evaporation. Its downward penetration ability is also good, reaching the lower ends of long clothes and trousers, ensuring overall drying of the entire garment. The second air outlet 142 blows air outwards at an angle. This is because the drying rod is actually offset outwards (away from the center of the drying machine) relative to the air outlet 14. The angled outward airflow can cover the outer side and edge areas of the clothing (such as the outer sleeves). The oblique airflow disperses the humid and hot air around the clothing, avoiding local humidity saturation, while also enhancing air convection between the clothing.

[0055] Therefore, the combined design of the first air outlet 141 and the second air outlet 142 in this solution can cover the clothes for drying in both vertical and horizontal directions, achieving rapid drying of the clothes as a whole.

[0056] In one embodiment, the length ratio of the first air outlet 141 to the length of the second air outlet 142 is 1.5:1 to 3:1.

[0057] The length ratio of the first air outlet 141 (vertically downward) to the second air outlet 142 (sloping outward) is limited to 1.5:1 to 3:1 (for example, when the length of the first air outlet 141 is 30mm, the length of the second air outlet 142 is 10-20mm). The length ratio is finely adjusted according to the size of the duct body 11 and the target air volume distribution. Within the range of 1.5:1 to 3:1, the dominant air supply position of the first air outlet 141 is ensured, while the auxiliary role of the second air outlet 142 is fully utilized. The first air outlet 141 is longer and has a higher proportion, with a larger flow area, and can allocate 60% to 75% of the total air volume. This ensures that the vertically downward main airflow covers the core area of ​​the clothes, meets basic drying needs, and provides more air volume to blow vertically downward, ensuring that the bottom of long clothes and trousers can also be effectively dried. The second air outlet 142 is shorter and allocates 25% to 40% of the total air volume. By tilting outward, it supplements the edges and outer areas of the clothes, avoiding the problem of insufficient coverage by the main airflow.

[0058] In one embodiment, the fan 2 includes a volute 21 and an impeller 22 located inside the volute 21. The volute 21 has a capacity-enhancing protrusion 211 on the side facing away from the air supply duct 1, which increases the internal volume of the volute 21. The outer wall of the capacity-enhancing protrusion 211 is provided with a clearance groove 212 for avoiding the steel wire rope 41 of the clothes drying machine.

[0059] After the enlarged protrusion 211 increases the internal volume of the volute 21, the airflow generated by the impeller 22's rotation gains more space for diffusion, resulting in a more complete conversion of dynamic pressure to static pressure and effectively increasing the outlet air pressure. This enhances the delivery capacity of hot air within the duct. Furthermore, the larger internal volume reduces airflow velocity fluctuations within the volute 21, minimizing turbulence and ensuring smoother interaction between the impeller 22 and the airflow. This not only reduces energy loss and improves the overall efficiency of the fan 2 but also reduces intermittent air pressure fluctuations caused by airflow turbulence, ensuring a continuous and stable drying process. In addition, reduced airflow disturbance directly lowers turbulent noise, and the smoother friction between the impeller 22 and the airflow avoids the generation of high-frequency noise. Combined with the streamlined design of the volute 21, the overall noise level of the fan 2 during operation is significantly reduced, improving the user experience.

[0060] When applying, refer to Figure 2 The main unit 10 is usually equipped with a lifting device 4, and the steel wire rope 41 of the lifting device 4 extends from both ends and connects downward to the clothes rack 20. In this solution, when installed in the main unit 10, the expansion protrusion 211 can be arranged vertically and vertically with the steel wire rope 41 by avoiding the clearance groove 212, which realizes the installation of the larger fan 2 in the main unit 10 with the inherent size, and avoids the impact on the steel wire rope 41.

[0061] On the other hand, a clothes drying rack is provided, including the aforementioned drying mechanism.

[0062] In practical applications, refer to Figure 1 The clothes drying rack includes a main unit 10 and a clothes rack 20. The main unit 10 is equipped with a lifting device 4, and the steel wire ropes 41 of the lifting device 4 extend from both ends and connect downwards to the clothes rack 20. The lifting device 4 can control the raising and lowering of the clothes drying rack. The main unit 10 is also equipped with a drying mechanism, which can blow drying air downwards to dry the clothes hanging under the clothes rack 20.

[0063] Similarly, based on the drying mechanism provided in this embodiment, the drying function of the clothes dryer in this embodiment has the advantages of sufficient air volume, good uniformity, and low energy consumption.
