Description
Technical Field
[0001] This utility model relates to the field of garment processing, and in particular to a garment drying device that provides uniform heating. Background Technology
[0002] With the fast pace of life, clothing drying equipment has become an essential appliance in homes and commercial settings. However, existing drying equipment generally suffers from poor heat uniformity. Traditional equipment often uses single-sided airflow or fixed hanging designs, which can easily create drying dead zones in certain areas of the clothing, resulting in clothes that are "dry on the outside but damp on the inside" and low drying efficiency. Utility Model Content
[0003] In view of the shortcomings mentioned above in the background technology, this utility model provides a garment drying device that provides uniform heating.
[0004] The present invention adopts the following technical solution: A garment drying device that provides uniform heating, characterized in that the drying device comprises: A drying oven, which has a drying chamber inside for drying operations; A ring-shaped clothes rack is installed inside the drying chamber and can be driven to rotate at a slow differential speed; A cylindrical drying drum is coaxially mounted at the center of an annular clothes rack and can rotate. The inside of the drying drum is hollow to form a cavity, and multiple ventilation holes communicating with the cavity are evenly distributed on its outer ring surface. A clothes hanger, multiple of which are suspended on the annular clothes rack and can rotate automatically under wind power, the clothes hanger includes a hook, a turbine mechanism and a body, the hook and the body being rotatably connected through the turbine mechanism; The axis of the ventilation hole is designed to form a tangential angle with the radius of the drying cylinder, so as to generate a rotating airflow in the drying chamber to drive the turbine mechanism to rotate the clothes hanger.
[0005] As a further improvement, the upper part of the annular clothes rack is connected to a turntable via multiple connecting rods, and the turntable is located at the top of the drying chamber and can rotate.
[0006] As a further improvement, the turntable is driven by a separate drive motor, and its rotation direction is opposite to that of the drying drum.
[0007] As a further improvement, the lower part of the annular clothes rack is provided with multiple positioning rings for hanging the clothes hangers.
[0008] As a further improvement, the turbine mechanism includes a connecting sleeve, a connecting arm, and blades. The two ends of the connecting sleeve are rotatably connected to the hook and the main body, respectively. Multiple blades are mounted on the outer ring surface of the connecting sleeve through the connecting arm, and they are driven to rotate by the tangential airflow blown from the drying cylinder.
[0009] As described above, this utility model has the following advantages compared to existing technologies: The drying device effectively solves many pain points of traditional drying equipment through its innovative design of "four core components + coordinated revolution and rotation." The device uses a drying chamber as the sealed load-bearing body, with an annular hanging rod and a coaxial cylindrical drying drum inside, along with a dedicated rotating clothes hanger, constructing a dual rotation mechanism of "revolution + rotation." The annular hanging rod and the drying drum rotate slowly in opposite directions. The drying drum sprays hot air through integrated tangential ventilation holes, forming a rotating airflow field that both drives the clothes hanger's rotation and enhances airflow turbulence. This ensures that clothes are heated from all angles, avoiding localized dampness and wrinkles. Furthermore, the integrated ventilation holes of the drying drum eliminate welding stress concentration, and the use of high-quality high-temperature resistant materials ensures a reliable and durable structure. Balancing drying efficiency, reliability, and convenience, it provides a superior solution for clothing drying. Attached Figure Description

[0015] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0016] As attached Figure 1 and Figure 4 As shown, a clothing drying device with uniform heating is provided. The device mainly consists of four core components: a drying box 1, a ring-shaped clothes hanging rod 2, a drying drum 3, and a clothes hanger 4. The components work together to form a dual rotation drying mechanism of "revolution + rotation" to ensure that the clothes are heated evenly.
[0017] As attached Figure 1As shown, the drying oven 1, serving as the main supporting structure of the entire device, is integrally stamped from high-strength, high-temperature resistant material. The side walls of the drying oven 1 are equipped with heat insulation layers to effectively reduce heat loss and improve energy efficiency. Inside, a closed drying chamber 11 is formed. The volume of the drying chamber 11 is designed according to the usage scenario, and the inner wall is polished, resulting in a smooth, burr-free surface that avoids scratching clothes and reduces airflow resistance. The front of the drying oven 1 features a sealable observation door 12 with a high-temperature resistant glass window, allowing users to easily observe the drying status of the clothes in real time. Sealing strips are installed around the edges of the observation door 12 to ensure the airtightness of the drying chamber 11 and prevent hot air leakage.
[0018] The ring-shaped clothes hanging rod 2 is horizontally set inside the drying chamber 11. It is made of lightweight, high-strength alloy material, which ensures structural stability while reducing the driving load. Its upper part is fixedly connected to the turntable 22 through multiple evenly distributed connecting rods 21. The turntable 22 is mounted on a bearing seat at the top of the drying chamber 11 and can rotate flexibly around the central axis of the drying chamber 11. The drive system of the turntable 22 consists of an independent variable frequency drive motor. The motor is connected to the turntable 22 through a gear transmission mechanism or a belt transmission mechanism, which can achieve slow stepless speed regulation of 0.5-2 r / min.
[0019] As attached Figure 1 and Figure 4 As shown, the lower part of the annular clothes hanging rod 2 is evenly provided with multiple positioning rings 23 along the circumference. The inner diameter of the positioning rings 23 is adapted to the hooks 41 of the clothes hangers 4, which not only ensures the stability of the clothes hangers 4 during hanging, but also reduces the swaying of the clothes hangers 4 during the revolution. It is worth noting that the rotation direction of the annular clothes hanging rod 2 is opposite to that of the cylindrical drying drum 3 mentioned later. This reverse rotation design can further enhance the turbulence of the airflow in the drying chamber 11, break the airflow stratification phenomenon, and allow heat to penetrate more evenly to all parts of the clothes.
[0020] As attached Figure 1 and Figure 3 As shown, the cylindrical drying drum 3 is coaxially positioned at the center of the annular clothes hanging rod 2, sharing the same axis of rotation with the annular clothes hanging rod 2. Its length matches the height of the drying chamber 11, ensuring that hot air can cover the entire drying area. The drying drum 3 is manufactured using a one-piece stainless steel molding process, with a hollow interior forming a cavity for conveying hot air. The cavity is connected to a hot air generating device (such as an electric heater or heat pump system) outside the drying chamber 1. Clean hot air (the temperature of which can be adjusted between 30-60℃) generated by the hot air generating device is conveyed into the cavity through pipes.
[0021] Multiple ventilation holes 33 are evenly distributed on the outer ring surface of the drying drum 3. The diameter of the ventilation holes 33 is 3-5mm, and the spacing between the holes is 8-10mm, ensuring uniform hot air spray. The key design is that the axis of the ventilation holes 33 is not along the radius of the drying drum 3, but forms a tangential angle of 15°-30° with the radius. This design allows the hot air ejected from the ventilation holes 33 to naturally carry a tangential velocity component, forming a stable rotating airflow field within the drying chamber 11. In addition, the ventilation holes 33 and the drying drum 3 are integrally molded, without any additional splicing parts or welding joints, completely avoiding structural fatigue problems caused by welding stress concentration, and significantly improving the structural strength and long-term operational reliability of the drying drum 3. At the same time, the integral molding design makes the outer ring surface of the drying drum 3 smooth and flat, without any gaps or protrusions, eliminating dead corners for hygiene. Fiber dust shed during the drying process does not easily accumulate, and daily cleaning only requires wiping with a cloth, resulting in extremely low maintenance costs.
[0022] The cylindrical drying drum 3 is also equipped with an independent drive motor, which is connected to the drying drum 3 through a separate gear transmission mechanism or belt transmission mechanism. Its rotation speed can be adjusted between 1-3 r / min, and the rotation direction is opposite to that of the ring hanging rod 2. This reverse rotation further enhances the airflow disturbance effect, allowing the hot air to come into fuller contact with the clothes.
[0023] As attached Figure 4 and Figure 5 As shown, the clothes hanger 4 is the core component for enabling the clothes to rotate. It is made of high-temperature and corrosion-resistant engineering plastic. Each device is equipped with 6-12 clothes hangers 4 (the number can be adjusted according to the volume of the drying chamber), which are evenly suspended on the positioning ring 23 of the annular hanging rod 2. The clothes hanger 4 mainly consists of three parts: hook 41, turbine mechanism 42, and body 43. The hook 41 is designed with an arc-shaped structure and a smooth surface, which can easily be hooked into the positioning ring 23 and is not easy to fall off. The body 43 is used to support the clothes. The hook 41 and the body 43 are rotatably connected through the turbine mechanism 42, ensuring that the body 43 can rotate flexibly relative to the hook 41.
[0024] The turbine mechanism 42 is the key to driving the rotation of the clothes hanger 4. It consists of three parts: a connecting sleeve 421, a connecting arm 422, and a blade 423. The connecting sleeve 421 is a hollow cylindrical structure with a high-precision bearing 424 installed inside. Its two ends are rotatably connected to the lower end of the hook 41 and the upper end of the main body 43, respectively, to ensure smooth rotation without jamming. Multiple connecting arms 422 are evenly distributed along the circumference on the outer ring surface of the connecting sleeve 421. The connecting arms 422 are perpendicularly connected to the connecting sleeve 421, and have high strength and are not easily deformed. A cylindrical blade 423 is installed at the end of the connecting arm 422. The axis of the blade 423 is perpendicular to the connecting arm 422, and the surface of the blade 423 is streamlined to effectively capture airflow power. When the vent 33 of the cylindrical drying drum 3 ejects tangential airflow, the airflow acts on the blades 423, generating a rotational torque along the axis of the connecting sleeve 421, which drives the turbine mechanism 42 to automatically rotate the main body 43 and the clothes at a speed of 5-10 r / min, thus realizing the rotation of the clothes.
[0025] The core advantage of this invention lies in its dual rotary drying mode of "revolution + self-rotation," and its workflow and coordination mechanism are as follows: After the device is started, the hot air generated by the hot air generator first enters the internal cavity of the cylindrical drying cylinder 3, and then is ejected through the ventilation holes 33 on the outer ring surface. Due to the tangential angle design of the ventilation holes 33, the ejected hot air forms a rotating airflow field and flows in the circumferential direction within the drying chamber 11. Meanwhile, the ring-shaped clothes rod 2 rotates slowly around the central axis under the drive of the independent drive motor, causing the clothes hanger 4 and clothes suspended on the positioning ring 23 to move along the ring track, so that the clothes pass through each area of the drying chamber 11 in sequence, avoiding insufficient heating in some areas. The rotating airflow acts on the turbine mechanism 42 and blades 423 of the clothes hanger 4, driving the main body 43 and the clothes to rotate, so that every side of the clothes can be evenly contacted by hot air, completely solving the problem of uneven heating of the back and sides of clothes in traditional drying equipment. The reverse rotation design of the ring-shaped clothes hanging rod 2 and the cylindrical drying drum 3 further exacerbates the turbulence of the airflow in the drying chamber 11, breaking the laminar flow of hot air and allowing heat to be distributed more evenly throughout the drying space. At the same time, the asynchronous revolution and rotation speeds of the clothes avoid local drying dead zones caused by the constant relative speed between the airflow and the clothes, ensuring that the clothes are fully dried from the inside out and from the surface to the folds.
[0026] In summary, this utility model drying device effectively solves many pain points of traditional drying equipment through its innovative design of "four core components + coordinated revolution and rotation". The device uses the drying chamber 1 as the sealed supporting body, and inside it is set an annular clothes hanging rod 2 and a coaxial cylindrical drying drum 3, which, together with a special clothes hanger 4 that can rotate on its own, constructs a dual rotation mechanism of "revolution + rotation". The annular clothes hanging rod 2 and the drying drum 3 rotate slowly in opposite directions. The drying drum 3 sprays hot air through the integrally formed tangential ventilation holes 33, forming a rotating airflow field, which both drives the clothes hanger 4 to rotate on its own and enhances the airflow disturbance. Its core advantages are significant: First, the dual-rotation and tangential airflow design ensures all-around heating of clothing, preventing localized dampness and wrinkles; second, the drying drum with 3 ventilation holes is integrally molded, eliminating welding stress concentration, and is made of high-quality high-temperature resistant materials, resulting in a reliable and durable structure; third, the smooth inner surface of the equipment prevents the accumulation of fiber dust, making cleaning and maintenance convenient. This device balances drying efficiency, reliability, and convenience, providing a superior solution for garment drying. The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
