Description

[0001] This application claims priority to Chinese Patent Application No. 202422788425.5, filed on November 14, 2024, entitled "A Clothes Drying Rack with Circular Drying Function", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of clothes drying rack technology, and more particularly to a clothes drying rack with a ring drying function. Background Technology

[0003] A clothes drying rack is a device that can achieve functions such as lifting, lighting, disinfection, and drying. It consists of components such as a motor, controller, clothes drying rod, lighting, disinfection lamp, and drying device.

[0004] As people's living standards improve, they pay more attention to quality of life and have higher requirements for the functionality and convenience of clothes drying racks. Therefore, the demand for high-performance, high-quality clothes drying racks is increasing. Current requirements for clothes drying racks not only require them to allow clothes to air dry naturally on sunny days with ample sunlight, but also to have an active drying function so that clothes can be quickly dried in damp, rainy weather, preventing bacteria growth and odors from developing on clothes in a humid environment.

[0005] Although existing clothes drying racks have drying functions, their drying systems usually only target the middle part of the drying rack, resulting in poor drying effect and a small drying range. Clothes usually hung on the small horizontal bar cannot be dried. Therefore, traditional clothes drying racks cannot meet consumers' drying needs in humid weather. Summary of the Invention

[0006] The purpose of this application is to provide a clothes drying machine with a ring drying function, which can solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, this application adopts the following technical solution: On the one hand, a clothes drying rack with a ring-shaped drying function is provided, including: The main unit casing has an internal installation space. Two or more sets of air duct components with the same external shape and structure, the air duct components form a drying air duct inside, all the drying air ducts are arranged in a ring in the installation space to jointly enclose and form a ring-shaped main unit air duct, the main unit housing is provided with a main unit air outlet facing the surface of the clothes being hung, the main unit air outlet is provided corresponding to the air duct components and forms a ring, and the main unit air duct is provided with an air duct outlet on the side facing the main unit air outlet. The air duct assembly also includes an air duct housing and a volute assembly. The volute assembly is disposed inside the air duct housing. The sidewall of the air duct housing and the sidewall of the volute assembly together form the drying air duct. A fan assembly is disposed inside the volute assembly.

[0008] On the other hand, a clothes drying rack with a ring-shaped drying function is provided, including: The main unit casing has an internal installation space. Two or more sets of air duct assemblies with the same external shape and structure, the air duct assembly including a volute assembly and a drying air duct communicating with the volute assembly, the volute assembly being disposed inside the drying air duct, and all the drying air ducts being arranged in a ring in the installation space; Along the width direction of the main housing, the volute assembly is located between the edge of the main housing and the centerline of the main housing, and a fan assembly matching the outer shell size of the volute assembly is disposed inside the volute assembly.

[0009] On the other hand, a clothes drying rack with a ring drying function is provided. The main unit casing has an internal installation space. Two or more sets of air duct assemblies with the same external shape and structure, the air duct assembly including a volute assembly and a drying air duct communicating with the volute assembly, all the drying air ducts being arranged in a ring in the installation space; The air duct assembly has a first air duct and a second air duct extending in different directions. The volute assembly includes a first volute air outlet, which is connected to the first air duct. The angle between the direction of the airflow blown out from the first volute air outlet and the extension direction of the first air duct is α, where 15°≤α≤60°. On the other hand, a clothes drying rack with a ring-shaped drying function is provided, including: The main unit housing and the drying rack are provided. An installation space is formed inside the main unit housing. The drying rack is suspended below the main unit housing by a steel wire rope. Inside the main unit housing, the steel wire rope extends along the length of the main unit housing from the center line in the width direction of the main unit housing. Two or more sets of air duct assemblies with the same external shape and structure, wherein the air duct assembly forms a drying air duct, and all the drying air ducts are arranged in a ring in the installation space; The drying air duct includes a first air duct and a second air duct that are perpendicular to each other. The first air duct is arranged along the length direction of the main unit housing, and the second air duct is arranged along the width direction of the main unit housing. A turbine fan is installed at the connection between the corresponding first air duct and the second air duct, and is located on the same side of the steel wire rope as the corresponding first air duct.

[0010] The beneficial effects of this application are as follows: In this embodiment, by forming an annular air duct inside the main unit housing and providing an annular air outlet corresponding to the air duct, an annular drying air can be blown from the main unit housing onto the clothes. This annular drying air acts directly on the clothes, accelerating the airflow speed on the clothing surface and saving drying time. Furthermore, the annular drying air forms an air wall that separates the inside from the outside, preventing low-temperature outside air from entering the air wall. This keeps the temperature inside the air wall relatively high, accelerating the drying speed of clothes inside the air wall and improving drying efficiency.

Detailed Implementation

[0014] 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.

[0015] A clothes drying rack is a device that can achieve functions such as lifting, lighting, disinfection, and drying. It consists of components such as a motor, controller, clothes drying rod, lighting, disinfection lamp, and drying device.

[0016] As people's living standards improve, they pay more attention to quality of life and have higher requirements for the functionality and convenience of clothes drying racks. Therefore, the demand for high-performance, high-quality clothes drying racks is increasing. Current requirements for clothes drying racks not only demand that clothes be hung to air dry naturally on sunny days with ample sunlight, but also that they have an active drying function to quickly dry clothes in damp, rainy weather, preventing bacteria growth and odors from developing on clothes in a humid environment. Existing clothes drying racks with drying functions typically only have a small, localized drying range. Some racks have multiple air outlets, but these outlets are independent, meaning only clothes hanging at the corresponding outlet area are dried, while other areas remain untreated. This significantly limits the number of clothes that can be dried. Therefore, traditional clothes drying racks struggle to meet consumers' drying needs in humid weather.

[0017] Based on the above, this application provides a clothes drying rack with a circular drying function that can cover the entire drying area of ​​the clothes drying rack, such as... Figure 1-13 As shown, this application embodiment provides a clothes drying rack with a ring drying function, including: a main body housing 100, with an installation space formed inside; Two or more air duct assemblies 200 with the same external shape and structure are provided. The air duct assembly 200 forms a drying air duct 230 inside. All the drying air ducts 230 are arranged in a ring in the installation space to jointly enclose and form a ring-shaped main unit air duct. The main unit housing 100 is provided with a main unit air outlet 140 facing the surface of the clothes to be hung. The main unit air outlet 140 is provided corresponding to the air duct assembly 200 and forms a ring. The main unit air duct is provided with an air duct outlet 240 on the side facing the main unit air outlet 140.

[0018] In this embodiment, an annular air duct is formed within the main unit housing 100, and an annular air outlet is provided correspondingly to the air duct. This allows an annular drying airflow to be blown from the main unit housing 100 onto the clothes. The annular drying airflow directly acts on the clothes, accelerating the airflow speed on the clothing surface and saving drying time. Furthermore, the annular drying airflow forms an air wall 150, separating the interior of the air wall 150 from the outside, preventing low-temperature outside air from entering the air wall 150. This maintains a higher temperature within the air wall 150, accelerating the drying speed of clothes within the air wall 150 and improving drying efficiency. Both the main unit air outlet 140 and the main unit air duct are annular and correspondingly arranged, ensuring that the drying air generated in the main unit air duct is blown out through the corresponding main unit air outlet 140, avoiding excessive airflow that could lead to airflow loss and heat dissipation.

[0019] Meanwhile, the air duct components 200 in the main housing 100 of this application have the same external structure, which can reduce the number of processing molds to be developed and save manufacturing costs.

[0020] It is understandable that the above-mentioned air duct components 200 having the same external structure means that the main structure of all air duct components 200 in this solution can be made by the same mold, and does not mean that their external details are exactly the same. For example, errors generated during the processing, or accessory structures formed on their main body by other processing methods, may cause differences between air duct components 200.

[0021] Specifically, refer to Figure 7-9 As shown, the air duct assembly 200 in this embodiment includes an air duct housing 210 and a volute assembly 220. The volute assembly 220 is disposed inside the air duct housing 210. The sidewall of the air duct housing 210 and the sidewall of the volute assembly 220 together form the drying air duct 230. A fan assembly 300 is disposed inside the volute assembly 220.

[0022] By integrating the volute assembly 220 with the duct housing 210, the connecting flange and seals between the volute assembly 220 and the duct housing 210 are eliminated, reducing resistance loss during airflow and thus improving the overall efficiency of the system. At the same time, it facilitates the optimization of airflow distribution in the system, reduces eddies and separation phenomena, and improves airflow uniformity. Due to the reduction of connecting parts, air leakage is greatly reduced, improving the system's sealing performance.

[0023] Because the volute assembly 220 is integrated with the duct housing 210, the number of connecting parts is reduced, thereby reducing vibration. The integrated design can better organize airflow, reduce friction between airflow and the wall, and thus reduce noise.

[0024] The integrated design makes the system structure more compact, reduces space occupation, simplifies installation steps, and facilitates the miniaturization of clothes drying racks.

[0025] The volute assembly 220 is positioned on one side of the centerline along the width direction of the main housing 100. Since the steel wire rope 500 connecting the drying rack 400 needs to extend from the centerline of the drying main unit and connect to the middle of the drying rack 400, this application addresses this by positioning the volute assembly 220 on one side of the centerline. This prevents interference with the steel wire rope 500 located on the centerline, eliminating the need to adjust the position of the steel wire rope 500. Positioning the steel wire rope on the centerline best ensures the stability of lifting and lowering, and also shortens the length of the steel wire rope 500.

[0026] Preferably, the volute assembly 220 of all the air duct assemblies 200 are arranged symmetrically within the main housing 100. By symmetrically arranging the air duct assemblies 200 within the main housing, the center of gravity of the air duct assembly 200 is located at its geometric center, making it easier to ensure the stability of the clothes drying rack installation and avoiding uneven force caused by a tilted center of gravity, which would affect installation and use.

[0027] Preferably, refer to Figure 6-9 As shown, in this embodiment of the application, the air duct assembly 200 consists of two sets, each having a first air duct 231 and a second air duct 232 that are perpendicular to each other. The two sets of air duct assemblies 200 are arranged in a centrally symmetrical manner in the installation space, so that the two first air ducts 231 and the two second air ducts 232 together form a ring-shaped host air duct.

[0028] By using two sets of air duct components 200 to form a ring-shaped main air duct, one set of air duct components 200 provides drying air to the two perpendicular sides of the clothes drying machine. The drying air can be controlled to enter the first air duct 231 and / or the second air duct 232 by a simple baffle, so as to achieve flexible control of the drying area of ​​the clothes drying machine. While achieving ring-shaped full-area drying, only two fans are used for air supply, saving product costs.

[0029] As a preferred technical solution, the host housing 100 in this embodiment has a rectangular structure, referring to... Figure 2 , 5 As shown, it has a first sidewall 110 and a second sidewall 120 that are perpendicular to each other. The first air duct 231 is arranged parallel to the first sidewall 110 and close to the inner wall of the first sidewall 110, and the second air duct 232 is arranged parallel to the second sidewall 120 and close to the inner wall of the second sidewall 120.

[0030] By setting the first air duct 231 parallel to and close to the inner wall of the first side wall 110, and setting the second air duct 232 parallel to and close to the inner wall of the second side wall 120, the drying air duct 230 is basically located in the outermost area of ​​the main housing 100, and the resulting annular air wall 150 is as large as possible. The four sides of the annular air wall 150 correspond to the frame of the rectangular drying rack 400, so that the clothes drying on the frame of the drying rack 400 (main drying rod, telescopic drying rod and small crossbar) are exposed to the direct blowing of the drying air as much as possible, resulting in a good drying effect. The large annular air wall 150 covers a large drying area, which can meet the drying needs of more clothes.

[0031] Reference Figure 2 , 5As shown, the main unit air outlet 140 in this embodiment includes a first air outlet 141 and a second air outlet 142. The first air outlet 141 and the second air outlet 142 are arranged perpendicular to each other. The first air duct 231 corresponds to the first air outlet 141, and the second air duct 232 corresponds to the second air outlet 142. The length of the first air duct 231 is longer than the length of the first air outlet 141, and the length of the second air duct 232 is longer than the length of the second air outlet 142.

[0032] The first air duct 231 corresponds to the first air outlet 141, and the second air duct 232 corresponds to the second air outlet 142. By setting the length of the first air duct 231 to be longer than the length of the first air outlet 141, and the length of the second air duct 232 to be longer than the length of the second air outlet 142, the first air outlet 141 and the second air outlet 142 are completely covered by the first air duct 231 and the second air duct 232 in the length direction. The drying air blown out by the first air outlet 141 and the second air outlet 142 is actively blown out by the first air duct 231 and the second air duct 232 without the need for lateral diffusion. Therefore, the wind speed can be guaranteed. The high wind speed can increase the airflow speed on the surface of the clothes being hung, thereby improving the drying efficiency. On the other hand, it ensures that the wind wall 150 has no weak points in terms of wind force, and can effectively isolate the inside and outside of the wind wall 150.

[0033] Specifically, refer to Figure 1 , 6 As shown, the clothes drying machine with ring drying function described in this embodiment also includes a drying rack 400 and a drive mechanism 600 for driving the drying rack 400 to rise and fall. The drying rack 400 is suspended below the main housing 100 by a steel wire rope 500. One end of the steel wire rope 500 is connected to the middle of the drying rack 400 and the other end is connected to the drive mechanism 600.

[0034] The drying rack 400 is suspended below the main drying unit and typically includes a main drying rod. Optionally, telescopic drying rods are provided at both ends of the main drying rod. The telescopic drying rods are used to extend the drying length of the drying rack 400 so that it can dry more clothes. In this embodiment, the main unit's air outlet 140 is arranged parallel to the main unit's air outlet 140 and above the main unit's air outlet 140. The drying air blown from the main unit's air outlet 140 can directly blow onto the clothes hanging on the main drying rod. The drying rack 400 is driven to rise and fall by the drive mechanism 600. The rising state of the drying rack 400 indicates that the clothes are hung or that no clothes need to be hung. When it is necessary to hang clothes on the drying rack 400, the driving mechanism 600 can be used to control the drying rack 400 to fall. After the drying rack 400 falls to an appropriate height to complete the hanging of clothes, the driving mechanism 600 can be used to control the drying rack 400 to rise again to the drying position to dry and dry the clothes.

[0035] Specifically, refer to Figure 5 , 6 As shown in Figure 13, the drive mechanism 600 includes a drive motor 610 and a transmission component 620 that is connected to the power output end of the drive motor 610. The transmission component 620 is located on the center line of the width direction of the main housing 100 so that the wire rope 500 extends along the length direction of the main housing 100 on the center line of the width direction of the main housing 100.

[0036] In this embodiment, by setting the transmission component 620 on the center line of the width direction of the main housing 100, the wire rope 500 extends along the length direction of the main housing 100 on the center line of the width direction of the main housing 100, so that the length of the wire rope 500 is the shortest and the force is the most balanced, reducing the possibility of wire skipping and jamming.

[0037] The transmission assembly 620 includes a transmission gear set and a winding wheel. One end of the transmission gear set is connected to the power output end of the drive motor 610, and the other end is connected to the winding wheel. The wire rope 500 is wound on the winding wheel. The rotation of the winding wheel realizes the winding and unwinding of the wire rope 500, thereby realizing the lifting and lowering of the drying rack 400 connected to the other end of the wire rope 500.

[0038] Preferably, in this embodiment, the two second air ducts 232 are located on both sides of the wire rope 500, and the wire rope 500 crosses the air duct assembly 200 above the first air duct 231.

[0039] In this embodiment, the wire rope 500 is configured to cross the air duct assembly 200 only above the first air duct 231, so that the shape of the air duct assembly 200 does not need to be changed in many places, and the ventilation effect of the air duct assembly 20 can be guaranteed.

[0040] This application also provides a specific air duct structure, referring to... Figure 8-9 As shown, the air duct housing 210 includes an upper air duct housing 211 and a lower air duct housing 212. The upper air duct housing 211 is provided with a wire groove 2111, and the steel wire rope 500 is embedded in the wire groove 2111, passing over the upper air duct housing 211 at the wire groove 2111.

[0041] In this embodiment, after the upper housing 211 and the lower housing 212 of the air duct are fastened together by the snap-fit ​​structure 213, a first air duct 231, a second air duct 232, and a volute assembly 220 are formed inside. The groove 2111 on the upper housing 211 corresponds to the second air duct 232 and is recessed into the second air duct 232. The function of the groove 2111 is to make way for the steel wire rope 500. Since the steel wire rope 500 will cross the second air duct 232, if the steel wire rope 500 and the second air duct 232 are simply stacked vertically, the height will increase, and the corresponding main housing 100 will need to be made thicker, thereby increasing the overall thickness of the clothes drying machine, wasting materials and affecting the aesthetics. In this embodiment, by setting the groove 2111 on the upper housing 211 of the air duct to allow the steel wire rope 500 to pass through, the upper surface of the steel wire rope 500 is lower than the upper surface of the upper housing 211 of the air duct, thus reducing the height and saving more space. Meanwhile, the second air duct 232 is recessed inward at the position corresponding to the line groove 2111, which can drastically reduce the flow area of ​​the second air duct 232 at this position. The reduction in flow area will increase the air velocity in the second air duct 232, thereby accelerating the wind speed blown out from the air outlet 140 of the main unit. This avoids the problem of the wind speed decreasing at the end of the air duct due to the excessive length of the air duct, making the drying air blown out from the air outlet 140 of the main unit more uniform and resulting in a better drying effect for clothes.

[0042] The clothes drying rack with a ring-shaped drying function described in this application embodiment, in addition to its drying function, also has a plasma disinfection function. Plasma disinfection is a highly efficient and safe sterilization technology that utilizes high-energy particles generated by plasma, ultraviolet light, ozone, and other active substances to sterilize and disinfect object surfaces. Plasma is a highly ionized gas containing a large number of active particles such as electrons, ions, and free radicals. These particles have extremely strong oxidizing capabilities, which can destroy the cell walls, proteins, and nucleic acids of microorganisms, thereby achieving the purpose of sterilization and disinfection.

[0043] Specifically, refer to Figure 8 As shown, in this embodiment, a plasma mounting groove 260 is provided on the outside of the air duct housing 210, a plasma generator 270 is provided in the plasma mounting groove 260, and a plasma emitting head 280 is connected to the plasma generator 270. The plasma emitting head 280 passes through the air duct housing 210 and extends into the interior of the air duct housing 210.

[0044] The plasma generator 270 generates plasma by ionizing gas using a high-voltage electric field or radio frequency. A plasma emitter 280 is connected to the plasma generator 270 and is responsible for directionally emitting the generated plasma and controlling its shape, size, and energy. In this embodiment, one or more plasma emitters 280 can be connected to a single plasma generator 270; the specific number of connections can be appropriately selected by those skilled in the art based on actual needs.

[0045] To further ensure uniform airflow at various locations within the duct, this embodiment also includes a flow divider 250 inside the duct housing 210. The flow divider 250 is positioned between the volute outlet of the volute assembly 220 and the duct outlet 240 of the duct assembly 200. By providing the flow divider 250, excessive airflow at the duct outlet 240 directly opposite the volute outlet can be avoided, preventing insufficient airflow or even no airflow at other duct outlets 240.

[0046] Specifically, refer to Figure 11 , 12 As shown, in this embodiment, the diverter plate 250 is disposed in the first air duct 231 and located between the first volute air outlet 221 and the air duct outlet 240 in the first air duct 231, and is set at an angle to the extension direction of the first air duct 231.

[0047] When the drying air blown out of the volute air outlet blows toward the splitter plate 250, part of it blows toward the back of the splitter plate 250 (the side away from the volute air outlet) and the other part blows toward the front of the splitter plate 250. Part of the drying air blown toward the back of the splitter plate 250 is blown out from the air outlet 240 of the air duct located behind the splitter plate 250, and part of it continues to flow downstream. The drying air blown toward the front of the splitter plate 250 flows directly downstream of the first air duct 231 after being blocked by the splitter plate 250. This avoids the situation where too much drying air is blown out from the air outlet 240 of the air duct directly opposite the volute air outlet.

[0048] It is understood that the above-mentioned diverter plate 250 is disposed in the first air duct 231 and is not intended to limit this application. In other embodiments, the diverter plate 250 may be disposed in the second air duct 232, or the diverter plate 250 may be disposed in both the first air duct 231 and the second air duct 232.

[0049] Preferably, in a further optional embodiment of this application, the diverter plate 250 may be configured as multiple pieces, and / or the position of the diverter plate 250 inside the air duct housing 210 is adjustable.

[0050] By setting multiple flow dividers 250, the airflow within the entire duct can be effectively controlled, ensuring uniform and stable airflow. Furthermore, by making the flow dividers 250 adjustable, the airflow distribution within the duct can be flexibly adjusted as needed to achieve a more ideal drying effect.

[0051] Furthermore, refer to Figure 9 , 10 As shown in the embodiment of this application, a heater mounting groove 214 is provided inside the air duct housing 210, and a support rib 2141 is provided on the inner wall of the heater mounting groove 214. A PTC heater 215 is mounted in the heater mounting groove 214 by the support rib 2141.

[0052] PTC is an abbreviation for Positive Temperature Coefficient. The PTC heater 215 is an electric heating element that utilizes the characteristic that the resistance of PTC ceramic material increases with temperature to achieve automatic constant temperature heating. When energized, the temperature of the PTC ceramic element gradually rises, and its resistance increases accordingly. When the temperature reaches a certain value (Curie temperature), the resistance increases sharply, thereby limiting the current and stabilizing the temperature of the PTC element around that value.

[0053] By setting the heater mounting groove 214, the PTC heater 215 can be fixed in a fixed position in the air duct housing 210. The support rib 2141 reduces the contact area between the PTC heater 215 and the air duct housing 210, thereby reducing the heat diffusion from the PTC heater 215 to the air duct housing 210, reducing heat loss and improving the heating efficiency of the airflow inside the air duct housing 210.

[0054] It is understandable that, in specific applications, those skilled in the art may also use other heaters as needed, such as electric heating wire heaters, quartz tube heaters, ceramic heaters, carbon fiber heaters, etc.

[0055] Preferred, refer to Figure 2 , 9 As shown in the embodiment of this application, the clothes drying rack with ring drying function also includes a lighting module 700, a voice control module 800, and a thermistor 900. The lighting module 700 is disposed on the side of the main unit housing 100 away from the mounting surface. The main unit air outlet 140 is disposed between the periphery of the lighting module 700 and the main unit housing 100. The thermistor 900 is disposed in the main unit air duct.

[0056] The lighting module 700 is a flat panel lamp, and the air outlet 140 of the main unit is arranged around the periphery of the flat panel, etc., to provide lighting for the clothes drying machine. The voice control module 800 is electrically connected to the clothes drying machine's electrical control box and is used to control the operation of the clothes drying machine by voice. The thermistor 900 is used to monitor the airflow temperature inside the air duct of the main unit in real time, thereby controlling the drying temperature.

[0057] During operation of the clothes drying machine with an annular drying function described in this embodiment, the PTC heater 215 starts the worm gear fan. The airflow generated by the worm gear fan flows out through the first volute air outlet 221 and the second volute air outlet 222. The airflow from the first volute air outlet 221 flows through the PTC heater 215 and enters the first air duct 231. It is then blown out from the first air outlet 141 corresponding to the first air duct 231 to dry the clothes. The airflow from the second volute air outlet 222 enters the second air duct 232 and is blown out from the second air outlet 142 corresponding to the second air duct 232 to dry the clothes. The drying air blown out from the first air outlet 141 and the second air outlet 142 together form an annular air wall 150. The air wall 150 isolates the internal and external spaces, causing the internal temperature to rise and resulting in a better drying effect.

[0058] The thermistor 900 provides feedback on the internal temperature of the drying duct 230. When the temperature exceeds the preset value, it continuously starts and stops the heating module to achieve constant control of the outlet air temperature, thus achieving a constant temperature drying effect. There are multiple plasma emitters 280 that extend into the duct. When the disinfection function is activated, the user can select the appropriate plasma emitter 280 to work as needed, thereby disinfecting part of the area or the entire area.

[0059] The lighting module 700 also includes ambient lights. The panel lights are mainly used for illumination. The ambient lights are respectively set to correspond to the first air outlet 141 and the second air outlet 142. If the user only activates the drying or disinfection function on the end cover side, only the ambient light corresponding to the second air outlet 142 will light up. If the user only activates the drying or disinfection function on the side panel side, only the ambient light corresponding to the first air outlet 141 will light up. When the user activates the full circle of drying or disinfection functions, the ambient lights corresponding to the first air outlet 141 and the second air outlet 142 will all light up, so that the user can clearly observe the area where the corresponding function is activated.

[0060] Meanwhile, this application also provides a clothes drying rack with a ring-shaped drying function, including: The main unit casing 100 has an internal installation space; Two or more sets of air duct assemblies 200 having the same external shape and structure, wherein the air duct assembly 200 includes a volute assembly 220 and a drying air duct 230 communicating with the volute assembly 220, wherein the volute assembly 220 is disposed inside the drying air duct 230, and all the drying air ducts 230 are arranged in a ring in the installation space. Along the width direction of the main housing 100, the volute assembly 220 is located between the edge of the main housing 100 and the center line of the main housing 100, and a fan assembly 300 matching the outer shell size of the volute assembly 220 is disposed inside the volute assembly 220.

[0061] Reference Figure 6 As shown, in this embodiment, the volute assembly 220 is positioned so that it extends from the edge near the main housing 100 to the center line near the main housing 100, allowing a single volute assembly 220 to occupy nearly half of the main housing 100. Compared to existing solutions, this embodiment uses a larger volute assembly 220. The size of the volute assembly 220 determines the amount of airflow it generates. In this application, by making the volute assembly 220 as large as possible, it can provide a larger airflow. A larger airflow can generate stronger drying air, providing a better drying effect for the clothes dryer.

[0062] It should be noted that the term "close" in this application specifically refers to the sidewall of the volute assembly 220 coinciding with or nearly coinciding with the sidewall of the main housing 100, and the sidewall of the volute assembly 220 nearly coinciding with the centerline.

[0063] Optionally, continue to refer to Figure 6 As shown, in the width direction of the main unit housing 100, the size of the main unit housing 100 is D1, and the size of the volute assembly 220 is D2. D2 / D1 = L1, and 1 / 2 > L1 > 1 / 3 are defined.

[0064] In this embodiment, by placing the volute assembly 220 inside the drying duct 230, the size of the volute assembly 220 increases, and the size of the drying duct 230 also increases. Therefore, the problem of the volute assembly 220 compressing the size of the drying duct 230 will not occur. At the same time, the volute assembly 220 will not interfere with the lifting drive device and transmission device of the drying rack 400 set in the main housing 100. Thus, a more reasonable system layout is formed, which can make fuller use of the internal space of the main housing 100, making the volute assembly 220 as large as possible. According to fluid dynamics theory, the air volume of the centrifugal fan is positively correlated with the volume of the volute (Q=k·V, where k is the proportionality coefficient and V is the effective volume of the volute). The increase in volume directly leads to the increase in air volume, thereby improving the drying effect of the clothes dryer.

[0065] Furthermore, refer to Figure 2 , 7 As shown, the overall thickness of the main unit housing 100 in this application is D3, 70 mm ≤ D3 ≤ 100 mm, and the thickness of the air duct assembly 200 is D4, 45 mm ≤ D4 ≤ 90 mm.

[0066] In a preferred embodiment of this application, the overall thickness D3 of the main housing 100 is 80 mm, and the thickness D4 of the air duct assembly 200 is 55 mm.

[0067] The overall thickness of the main unit casing 100 is D3, which is an ultra-thin model in the clothes drying rack industry. The ultra-thin form of the clothes drying rack occupies less space when installed and does not protrude significantly from the ceiling, which is an important development trend of clothes drying racks today. With the main unit casing 100 of the clothes drying rack being thinner, the installation space for the traditional air duct component 200 and fan structure will be even smaller. This will result in a small drying air volume in the clothes drying rack, making it difficult to meet the needs of quickly drying a large number of clothes.

[0068] In this application, the space ratio of the drying air duct 230 and the turbine fan in the main unit housing 100 is increased through the above design, and this improvement is more prominent in the Ultra-Bet model.

[0069] In this embodiment of the application, the air duct assembly 200 consists of two sets, each having a first air duct 231 and a second air duct 232 that are perpendicular to each other. The two sets of air duct assemblies 200 are arranged in a centrally symmetrical manner in the installation space, so that the two first air ducts 231 and the two second air ducts 232 together form a ring-shaped host air duct.

[0070] Two sets of air duct components 200 together form a ring-shaped main unit air duct, which generates a ring-shaped drying airflow. This ring-shaped drying airflow directly acts on the clothes, accelerating the airflow speed on the surface of the clothes and thus saving drying time. Furthermore, the ring-shaped drying airflow forms an air wall 150, separating the interior of the air wall 150 from the outside, preventing cold outside air from entering the interior of the air wall 150. This maintains a higher temperature within the air wall 150, thereby accelerating the drying speed of clothes within the air wall 150 and improving drying efficiency. Both the main unit air outlet 140 and the main unit air duct are ring-shaped and correspondingly positioned, ensuring that the drying air generated in the main unit air duct is blown out through the corresponding main unit air outlet 140, avoiding excessive airflow that could lead to airflow loss and heat dissipation.

[0071] Furthermore, refer to Figure 9As shown, the volute assembly 220 in this embodiment includes a first volute air outlet 221, which is connected to the first air duct 231. The angle between the airflow direction blown out from the first volute air outlet 221 and the extension direction of the first air duct 231 is less than 90°. By setting the air outlet direction of the first volute air outlet 221 and the airflow extension direction of the first air duct 231 to an angle of less than 90°, the drying air blown out of the first volute air outlet 221 can enter the first air duct 231 with minimal resistance, thereby reducing wind energy loss. The air volume is large and the wind speed is fast, which makes the drying air blown out by the clothes dryer more efficient. Under the same turbine fan power, the drying effect of this solution is better and the efficiency is higher.

[0072] It is understandable that although the larger the size of the volute assembly 220, the greater the air volume, and theoretically the larger the internal space it occupies in the main unit housing 100, the better. However, in actual use, its thickness and positional relationship with other functional components inside the main unit housing 100 also need to be considered. Therefore, in this embodiment, the volute assembly 220 is located on one side of the centerline along the width direction of the main unit housing 100; the volute assemblies 220 of all the air duct assemblies 200 are arranged in a centrally symmetrical manner within the main unit housing 100.

[0073] By placing the volute assembly 220 on one side of the centerline, it will not interfere with the wire rope 500 located on the centerline. Therefore, there is no need to adjust the setting position of the wire rope 500. The wire rope being located on the centerline can best ensure the stability of lifting and shorten the arrangement length of the wire rope 500.

[0074] Optionally, refer to Figure 2 , 5 As shown, the main unit housing 100 has a rectangular structure and has a first side wall 110 and a second side wall 120 that are perpendicular to each other. The first air duct 231 is arranged parallel to the first side wall 110 and close to the inner wall of the first side wall 110, and the second air duct 232 is arranged parallel to the second side wall 120 and close to the inner wall of the second side wall 120.

[0075] By setting the first air duct 231 parallel to and close to the inner wall of the first side wall 110, and setting the second air duct 232 parallel to and close to the inner wall of the second side wall 120, the drying air duct 230 is basically located in the outermost area of ​​the main housing 100, and the resulting annular air wall 150 is as large as possible. The four sides of the annular air wall 150 correspond to the frame of the rectangular drying rack 400, so that the clothes drying on the frame of the drying rack 400 (main drying rod, telescopic drying rod and small crossbar) are exposed to the direct blowing of the drying air as much as possible, resulting in a good drying effect. The large annular air wall 150 covers a large drying area, which can meet the drying needs of more clothes.

[0076] Optionally, all the drying air ducts 230 are arranged in a ring in the installation space to jointly enclose and form a ring-shaped main unit air duct. The main unit housing 100 is provided with a main unit air outlet 140 facing the surface of the clothes being hung. The main unit air outlet 140 is provided corresponding to the air duct assembly 200 and forms a ring. The main unit air duct is provided with an air duct outlet 240 on the side facing the main unit air outlet 140.

[0077] In this embodiment, an annular air duct is formed within the main unit housing 100, and an annular air outlet is provided correspondingly to the air duct. This allows an annular drying airflow to be blown from the main unit housing 100 onto the clothes. The annular drying airflow directly acts on the clothes, accelerating the airflow speed on the clothing surface and saving drying time. Furthermore, the annular drying airflow forms an air wall 150, separating the interior of the air wall 150 from the outside, preventing low-temperature outside air from entering the air wall 150. This maintains a higher temperature within the air wall 150, accelerating the drying speed of clothes within the air wall 150 and improving drying efficiency. Both the main unit air outlet 140 and the main unit air duct are annular and correspondingly arranged, ensuring that the drying air generated in the main unit air duct is blown out through the corresponding main unit air outlet 140, avoiding excessive airflow that could lead to airflow loss and heat dissipation.

[0078] Optionally, the main unit air outlet 140 includes a first air outlet 141 and a second air outlet 142. The first air outlet 141 and the second air outlet 142 are arranged perpendicular to each other. The first air duct 231 corresponds to the first air outlet 141, and the second air duct 232 corresponds to the second air outlet 142. The length of the first air duct 231 is longer than the length of the first air outlet 141, and the length of the second air duct 232 is longer than the length of the second air outlet 142.

[0079] The first air duct 231 corresponds to the first air outlet 141, and the second air duct 232 corresponds to the second air outlet 142. By setting the length of the first air duct 231 to be longer than the length of the first air outlet 141, and the length of the second air duct 232 to be longer than the length of the second air outlet 142, the first air outlet 141 and the second air outlet 142 are completely covered by the first air duct 231 and the second air duct 232 in the length direction. The drying air blown out by the first air outlet 141 and the second air outlet 142 is actively blown out by the first air duct 231 and the second air duct 232 without the need for lateral diffusion. Therefore, the wind speed can be guaranteed. The high wind speed can increase the airflow speed on the surface of the clothes being hung, thereby improving the drying efficiency. On the other hand, it ensures that the wind wall 150 has no weak points in terms of wind force, and can effectively isolate the inside and outside of the wind wall 150.

[0080] Furthermore, refer to Figure 6-9 As shown, in this embodiment, the volute assembly 220 is located at the corner where the first air duct 231 and the second air duct 232 connect.

[0081] By positioning the volute assembly 220 at the corner connecting the first air duct 231 and the second air duct 232, the volute assembly 220 can supply air to both the first and second air ducts 231 and 232 respectively. The drying air travels a shorter distance within these ducts, resulting in less loss during its movement. This allows for faster, larger, and more uniform airflow when the drying air exits from the first and second air ducts 231 and 232. In contrast, with traditional structures where the fan is located at one end of the air duct, the drying air blown by the fan needs to travel a longer distance to reach the end of the air duct. The airflow velocity decreases significantly towards the end, while the airflow velocity is very high near the fan. This results in significant unevenness in both airflow volume and velocity, leading to noticeable differences in drying performance for clothes hung in different positions. Clothes near the fan dry quickly, while those further away remain damp, requiring longer drying times, impacting usability, and wasting energy.

[0082] In summary, compared with the prior art, the clothes drying machine provided in this application embodiment can form a larger drying air wall 150 to form a ring drying space. The air volume of the air wall 150 is larger, resulting in better drying effect and higher efficiency, which can meet the needs of energy saving, environmental protection and high-efficiency use.

[0083] In another optional embodiment of this application, a clothes drying rack with a ring-shaped drying function is provided, comprising: The main unit casing 100 has an internal installation space; Two or more sets of air duct assemblies 200 with the same external shape and structure, wherein the air duct assembly 200 includes a volute assembly 220 and a drying air duct 230 connected to the volute assembly 220, and all the drying air ducts 230 are arranged in a ring in the installation space. The air duct assembly 200 has a first air duct 231 and a second air duct 232 extending in different directions. The volute assembly 220 includes a first volute air outlet 221, which is connected to the first air duct 231. The angle α between the direction of the airflow blown out from the first volute air outlet 221 and the extension direction of the first air duct 231 is less than 90°.

[0084] By setting the air outlet direction of the first volute air outlet 221 and the airflow extension direction of the first air duct 231 to an angle of less than 90°, the drying air blown out of the first volute air outlet 221 can enter the first air duct 231 with minimal resistance, thereby reducing wind energy loss. The air volume is large and the wind speed is fast, which makes the drying air blown out by the clothes dryer more efficient. Under the same turbine fan power, the drying effect of this solution is better and the efficiency is higher.

[0085] It is understood that the included angle α is not necessarily better the smaller it is. In this application, α ≥ 15°, α ≤ 60°. Further, 20° ≤ α ≤ 45°, and preferably, α = 30°.

[0086] As mentioned above, α is less than 90° to ensure that the drying air blown out by the volute assembly 220 enters the first air duct 231 more smoothly. However, in this application, the connection between the first volute outlet 221 and the first air duct 231 is not located at one end of the first air duct 231, but at a certain position in the middle of the length of the first air duct 231. After the drying air enters the first air duct 231 at the connection between the first volute outlet 221 and the first air duct 231, it needs to flow to both sides along the first air duct 231. When α < 15°, the airflow entering the side of the first air duct 231 near the second air duct 232 will be significantly reduced, which will cause a blind spot to form in this area, resulting in an unsatisfactory drying effect. Figure 14 , 15 As shown, simulation diagrams of airflow distribution under two different angles α are provided, in which... Figure 14 This is a simulation result when α is 30°. Figure 15 The image shows the simulation results when α is 10°. As can be seen from the image... Figure 15 An airflow blind zone was formed in the area within the dashed box, and Figure 14The airflow is obvious at the corresponding position. When α is less than 15°, the airflow on the side of the first air duct 231 closer to the second air duct 232 will be greatly reduced, and when α is greater than 60°, the airflow on the side of the first air duct 231 farther from the second air duct 232 will be greatly reduced. It is difficult to ensure the uniformity of airflow and wind speed in the entire air duct.

[0087] Furthermore, in this embodiment, the volute assembly 220 is integrally formed and disposed inside the air duct assembly 200. The integral formation of the volute assembly 220 inside the air duct assembly 200 eliminates the connecting flange and seals between the volute assembly 220 and the air duct housing 210, reducing resistance losses during airflow and thus improving the overall system efficiency. Simultaneously, it facilitates optimized airflow distribution within the system, reduces eddies and separation phenomena, and improves airflow uniformity. Due to the reduction in connecting parts, air leakage is significantly reduced, improving the system's sealing performance.

[0088] The integration of the volute assembly 220 with the duct housing 210 reduces connecting parts and thus lowers vibration. The integrated design better organizes airflow, reduces friction between the airflow and the wall, and consequently reduces noise. The integrated design also makes the system structure more compact, reduces space occupation, simplifies installation, and facilitates the miniaturization of the clothes drying rack.

[0089] Optionally, refer to Figure 11 As shown, the volute assembly 220 includes a main housing for mounting the impeller and an air guide wall panel 291 connected to the main housing. The first volute outlet 221 is disposed on the main housing. The air guide wall panel 291 connects the first volute outlet 221 to the first air duct 231. Along the width direction of the main housing 100, the air guide wall panel 291 extends obliquely from the center line near the center line of the main housing 100 towards the direction away from the center line of the main housing 100. The oblique arrangement of the air guide wall panel 291 helps to concentrate the air volume, which can reduce the decrease in air velocity away from the end of the first volute outlet 221, making the air volume and air velocity more uniform. At the same time, the air guide wall panel 291 serves as part of the volute assembly 220 on the one hand and as the side wall of the air duct on the other. This integrated design makes the overall structure more compact, reduces material costs, and reduces airflow resistance.

[0090] Further reference Figure 6-12 As shown, the clothes drying rack in this embodiment also includes a second air duct. The first air duct 231 and the second air duct 232 are arranged perpendicularly. The main housing is located at the connection between the first air duct 231 and the second air duct 232. The main housing shares a portion of the sidewall with the first air duct 231 and / or the second air duct 232.

[0091] Specifically, the main housing includes a first housing sidewall 292 and a second housing sidewall 293, wherein all or part of the first housing sidewall 292 and the second housing sidewall 293 serve as the sidewalls of the first air duct 231, and / or the second housing sidewall 293 serves as the sidewall of the second air duct 232.

[0092] By sharing the sidewalls of the main housing with the first air duct 231 and the second air duct 232, the product structure is simplified, the product weight is reduced, and the structure and components that generate wind resistance are reduced, so that the drying air can enter the first air duct 231 and the second air duct 232 more efficiently.

[0093] Meanwhile, this embodiment also specifically provides the formation methods of the first volute air outlet 221 and the second volute air outlet 222, referring to... Figure 11 As shown, the first housing sidewall 292 and the second housing sidewall 293 are spaced apart to form a first volute air outlet 221 for supplying air to the first air duct 231, and / or, to form a second volute air outlet 222 for supplying air to the second air duct 232.

[0094] A first notch and a second notch are formed at a distance between the first housing sidewall 292 and the second housing sidewall 293. The first notch forms the first volute air outlet 221, and the second notch forms the second volute air outlet 222.

[0095] Specifically, at the second notch, the first housing sidewall 292 abuts against the sidewall of the air duct assembly 200, the second housing sidewall 293 is spaced apart from the sidewall of the air duct assembly 200, and the second volute air outlet 222 is formed between the second housing sidewall 293 and the sidewall of the air duct assembly 200.

[0096] The first volute air outlet 221 extends from the top plate to the bottom plate of the main housing along the thickness direction of the main housing, that is, a first volute air outlet 211 is formed in the thickness direction of the main housing, which is approximately equal to the thickness of the main housing. The second volute air outlet 222 occupies only a portion of the height in the thickness direction of the main housing, that is, the second housing sidewall 293 only partially forms the second volute air outlet in the thickness direction of the main housing.

[0097] like Figure 9 , 11As shown, the air duct housing 210 includes two parts: an upper air duct housing 211 and a lower air duct housing 212. The second housing sidewall 293 is also divided into upper and lower parts, namely an upper sidewall 2931 located in the upper air duct housing 211 and a lower sidewall 2932 located in the lower air duct housing 212. The upper sidewall 2931 and / or the lower sidewall 2932 are provided with notches, and the second volute air outlet 222 for supplying air to the second air duct 232 is formed at the notches.

[0098] Specifically, such as Figure 9 As shown, in this embodiment, the notch 294 provided on the upper sidewall 2931 is located at one end of the width direction of the upper housing 211 of the air duct, and is formed in part of the upper sidewall 2931 in the thickness direction of the upper housing 211 of the air duct. like Figure 11 As shown, the notch 294 provided on the lower sidewall 2932 of the lower duct housing 212 is located at one end of the width direction of the lower duct housing 212 and is formed on the entire lower sidewall in the thickness direction of the lower duct housing 212. When the upper duct housing and the lower duct housing are engaged, the notch 294 on the upper sidewall 2931 and the lower sidewall 2932 together form the second volute air outlet 222.

[0099] In another optional embodiment of this application, a clothes drying rack with a ring-shaped drying function is provided, comprising: The main unit housing 100 and the drying rack 400 are provided. An installation space is formed inside the main unit housing 100. The drying rack 400 is suspended below the main unit housing 100 by a steel wire rope 500. Inside the main unit housing 100, the steel wire rope 500 extends along the length direction of the main unit housing 100 on the center line in the width direction of the main unit housing 100. Two or more sets of air duct assemblies 200 with the same external shape and structure, wherein the air duct assembly 200 forms a drying air duct 230 inside, and all the drying air ducts 230 are arranged in a ring in the installation space; The drying air duct 230 includes a first air duct 231 and a second air duct 232 that are perpendicular to each other. The first air duct 231 is arranged along the length direction of the main unit housing 100, and the second air duct 232 is arranged along the width direction of the main unit housing 100. The turbine fan is installed at the connection between the corresponding first air duct 231 and the second air duct 232, and is located on the same side of the steel wire rope 500 as the corresponding first air duct 231.

[0100] In this application, the first air duct 231 is arranged along the length of the main housing 100. As the main air duct of the clothes drying rack, it corresponds to a larger drying area and is longer, thus requiring a larger air volume and wind speed. By setting the turbine fan and the first air duct 231 on the same side of the wire rope 500, it is not necessary to thin the first air duct 231 or the turbine fan to avoid interference between the turbine fan or the first air duct 231 and the wire rope 500. In this way, a structure is formed in which the wire rope 500 does not affect the size of the turbine fan and the first air duct 231, ensuring the air volume in the first air duct 231.

[0101] Specifically, such as Figure 7 As shown, in order to ensure that the wire rope 500 does not affect the overall thickness of the main housing 100, in this embodiment, the range of motion of the wire rope 500 in the thickness direction of the main housing 100 is located between the upper and lower surfaces of the turbine fan. Thus, with a fixed thickness of the main housing 100, the turbine fan and the first air duct 231 can be made as thick as possible in the thickness direction of the main housing 100.

[0102] To further utilize the internal space of the main unit housing 100, in this embodiment, the main unit housing 100 is configured as a rectangular structure with a first sidewall 110 and a second sidewall 120 perpendicular to each other. The first air duct 231 is parallel to the first sidewall 110 and close to its inner wall, and the second air duct 232 is parallel to the second sidewall 120 and close to its inner wall. This configuration allows for the formation of an annular air duct with the largest coverage area within the effective area of ​​the main unit housing 100, thereby further enabling the main unit air outlet 140 corresponding to the annular air duct to cover as large an area as possible. This results in a wider drying coverage area for the clothes dryer, increasing the drying capacity. Simultaneously, with the same number of clothes, the clothes can be hung more dispersedly, which helps with ventilation and moisture evaporation.

[0103] Reference Figure 6 As shown, in this embodiment, there are two sets of air duct components 200. The two sets of air duct components 200 are arranged symmetrically at the center in the installation space, so that the two first air ducts 231 and the two second air ducts 232 together form a ring-shaped main unit air duct. By symmetrically arranging the air duct components 200 in the main unit housing 100, the center of gravity of the air duct components 200 is located at its geometric center, which makes it easier to ensure the stability of the clothes drying rack installation and avoids uneven force caused by the center of gravity tilt, which would affect the installation and use.

[0104] In the case of the two sets of air duct components 200 described above, the two first air ducts 231 are respectively located on both sides of the steel wire rope 500, and the steel wire rope 500 crosses the air duct component 200 above the second air duct 232. Since the second air duct 232 corresponds to the width direction of the clothes drying machine, its corresponding drying area is relatively short, and therefore, the required air volume is small. The steel wire rope 500 crosses the second air duct 232 above the second air duct 232. This can be achieved by partially setting a recessed structure on the second air duct 232 or by thinning the second air duct 232 as a whole to avoid interference with the steel wire rope 500. In this way, the drying effect is not affected and the overall thickness of the clothes drying machine is not increased, which can meet various needs.

[0105] Specifically, in this embodiment, a recessed structure is partially provided on the second air duct 232 to allow the wire rope 500 to cross the second air duct 232. The air duct assembly 200 includes an upper air duct housing 211 and a lower air duct housing 212. A wire groove 2111 is provided on the upper air duct housing 2111. The wire rope 500 is embedded in the wire groove 2111 and crosses the upper air duct housing 2111 at the wire groove 2111. It can be understood that in the above case, the wire groove 2111 is provided at the position of the air duct assembly 200 corresponding to the second air duct 232.

[0106] The above solution makes full use of the internal space of the main unit housing 100. Without increasing the size of the main unit housing 100, it maximizes the drying air volume and air speed of the clothes dryer by increasing the size of the turbine fan, maximizing the height of the air duct, and optimizing the air duct design to reduce wind resistance, resulting in a better overall effect.
