Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0022] The core of this application is to provide an internal circulation clothing drying device to achieve low energy consumption in drying clothes, reduce the risk of clothing damage, and reduce the influence of region and climate on drying effect.

[0023] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 A structural diagram of an internal circulation type clothes drying device provided in this application embodiment is shown below. Figure 1 As shown, the internal circulation clothes drying device includes: an outer cylinder 1, an inner cylinder 2, a fan 3, and a moisture-absorbing component 4; the inner cylinder 2 is suspended inside the outer cylinder 1, and the top and bottom of the inner cylinder 2 are open structures. A support component for carrying clothes is installed inside the inner cylinder 2. The fan 3 is installed inside the inner cylinder 2 and close to the bottom of the inner cylinder 2. The moisture-absorbing component 4 is arranged around the outer circumference of the inner cylinder 2, and the edge of the moisture-absorbing component 4 abuts against the inner wall of the outer cylinder 1. The internal cavity of the moisture-absorbing component 4 is used to hold moisture-absorbing material. The moisture-absorbing component 4 is provided with multiple through holes so that air can flow from the top of the outer cylinder 1 to the bottom of the outer cylinder 1 through the through holes.

[0025] This application embodiment does not specifically limit the shape and size of the outer cylinder 1 and the inner cylinder 2. The inner cylinder 2 is suspended inside the outer cylinder 1, and the inner cylinder 2 and the outer cylinder 1 are coaxially arranged. Regarding how the inner cylinder 2 is suspended inside the outer cylinder 1, a support beam 7 can be provided on the inner wall of the outer cylinder 1. The support beam 7 is connected to the outer wall of the inner cylinder 2, and the support beam 7 is used to position the inner cylinder 2 and suspend it inside the outer cylinder 1. This application embodiment does not specifically limit the number of support beams 7. To improve the stability of fixing the inner cylinder 2, multiple support beams 7 can be provided, and the support beams 7 are connected to the outer wall of the inner cylinder 2 near the top. Regarding the load-bearing components inside the inner cylinder 2, they can be any structural component capable of supporting clothing, such as a mesh tray or hooks. This application embodiment does not specifically limit the shape and number of moisture-absorbing components 4. The moisture-absorbing components 4 can be fixedly connected to or detachably connected to the outer periphery of the inner cylinder 2. One side of the moisture-absorbing component 4 is connected to the outer periphery of the inner drum 2, and the other side abuts against the inner wall of the outer drum 1. This ensures that humid air is dried by the moisture-absorbing component 4 before flowing out. The moisture-absorbing component 4 is used to create a humidity gradient difference between the outer drum 1 and the inner drum 2. For ease of understanding, the drying process of clothes in the inner drum 2 is described below: Air is pushed upward from the bottom of the inner drum 2 by the fan 3, carrying away the moisture from the damp clothes inside the inner drum 2 and becoming humid air. The humid air rises to the top of the outer drum 1 and disperses and sinks in all directions. It is then absorbed by the moisture-absorbing component 4 and becomes dry air. The dry air is then pushed upward by the bottom fan 3, passing through the wet clothes to absorb moisture. This cycle repeats, transferring moisture from the wet clothes to achieve the drying and moisture-absorbing effect. By planning a closed air circulation path, relying on the moisture-absorbing component 4 to create a humidity gradient difference in the closed circulation loop, and using the fan 3 to drive the air circulation in the loop, the extremely low humidity air is used as a carrier to promote the directional transfer of moisture in the wet clothes. Finally, the moisture evaporates quickly without the aid of heat, achieving low-carbon, energy-saving, and efficient clothes drying.

[0026] The internal circulation clothing drying device provided in this application includes: an outer cylinder 1, an inner cylinder 2, a fan 3, and a moisture-absorbing component 4; the inner cylinder 2 is suspended inside the outer cylinder 1, and the top and bottom of the inner cylinder 2 are open structures. A support component for carrying clothing is provided inside the inner cylinder 2. The fan 3 is located inside the inner cylinder 2 and close to the bottom of the inner cylinder 2. The moisture-absorbing component 4 is arranged around the outer circumference of the inner cylinder 2, and the edge of the moisture-absorbing component 4 abuts against the inner wall of the outer cylinder 1. The internal cavity of the moisture-absorbing component 4 is used to hold moisture-absorbing material. The moisture-absorbing component 4 is provided with multiple through holes so that air can flow from the top of the outer cylinder 1 to the bottom of the outer cylinder 1 through the through holes. In this application, air is propelled upwards from the bottom of the inner cylinder 2 by the fan 3, carrying away moisture from the wet items to become humid air. The humid air rises to the top of the outer cylinder 1 and then disperses and sinks in all directions, where it is absorbed by the moisture-absorbing component 4 to become dry air. The dry air is then pushed upwards by the fan 3, and the cycle repeats to transfer moisture from the wet items to dry the clothes. This application uses a closed-space air circulation method, which reduces the influence of region and climate on the drying effect. In addition, no heating is required, achieving low energy consumption for drying clothes and reducing the risk of damage to clothes.

[0027] Based on the above embodiments, the top opening of the outer cylinder 1 in this application embodiment is covered with an arc-shaped cover 5, and the middle part of the arc-shaped cover 5 is provided with a rounded corner 6. The arc opening of the rounded corner 6 is opposite to the arc opening of the arc-shaped cover 5.

[0028] In this embodiment, a rounded corner 6 is provided at the top inside the arc-shaped cover 5. This allows humid air to be deflected by the rounded corner 6 and dispersed downwards in all directions, ensuring that the humid air can sink to the interlayer area between the inner cylinder 2 and the outer cylinder 1, facilitating dehumidification of the humid air by the moisture-absorbing component 4. Furthermore, the smooth curve of the rounded corner 6 effectively reduces airflow resistance, making airflow smoother. This design better disperses the kinetic energy of the airflow and reduces air turning losses. The rounded corner 6 guides the airflow to turn smoothly, avoiding violent separation or eddies at the corner, thereby reducing flow losses. Correspondingly, a rounded corner can also be provided at the bottom inside the outer cylinder 1. This rounded corner is located at the bottom of the inner cylinder 2, and the arc opening of this rounded corner faces the opposite direction to the arc opening of the rounded corner 6 inside the arc-shaped cover 5, so that air is deflected by this rounded corner and flows into the inner cylinder 2. The arc-shaped cover 5 is hinged to the outer cylinder 1 via a hinge, and the arc-shaped cover 5 also facilitates the placement and removal of wet items into the inner cylinder 2.

[0029] Based on the above embodiments, Figure 2 This is a schematic diagram of a moisture-absorbing component provided in an embodiment of this application, as shown below. Figure 2As shown, in this embodiment of the application, the moisture-absorbing component 4 is a frustum-shaped moisture-absorbing component. The frustum-shaped moisture-absorbing component has a through hole 401 in the middle. The inner wall of the through hole 401 is connected to the outer wall of the inner cylinder 2. The bottom edge of the frustum-shaped moisture-absorbing component abuts against the inner wall of the outer cylinder 1.

[0030] In this embodiment, the moisture-absorbing component 4 is configured in a frustum shape to facilitate the storage of a larger amount of moisture-absorbing material. A through hole 401 is provided in the center of the frustum-shaped moisture-absorbing component. The inner diameter of the through hole 401 matches the outer diameter of the inner cylinder 2. The inner cylinder 2 is inserted into the center of the frustum-shaped moisture-absorbing component through the through hole 401. The height of the frustum-shaped moisture-absorbing component is less than the height of the inner cylinder 2. This embodiment does not limit the specific method of connecting the inner wall of the through hole 401 to the outer wall of the inner cylinder 2; it can be a bolt connection, etc.

[0031] Based on the above embodiments, in this application embodiment, the angle between the generatrix of the frustum-shaped moisture-absorbing component and the bottom surface of the frustum-shaped moisture-absorbing component is 45°, and multiple frustum-shaped moisture-absorbing components are spaced apart along the axial direction of the inner cylinder 2.

[0032] In this embodiment, the generatrix refers to the hypotenuse of the frustum-shaped moisture-absorbing component, i.e., the straight line from the circumference of the upper base to the circumference of the lower base. In this embodiment, the sidewall of the frustum-shaped moisture-absorbing component is set at 45 degrees. When humid air enters the frustum-shaped moisture-absorbing component at a 45-degree angle, the streamline changes. Due to the obstruction of the wall of the frustum-shaped moisture-absorbing component, the airflow needs to change direction, which leads to the formation of a pressure gradient. This pressure gradient causes the airflow to slow down because the airflow needs to overcome the pressure difference to continue flowing. The slowing down of the humid air entering the frustum-shaped moisture-absorbing component allows for sufficient contact with the moisture-absorbing material, achieving thorough drying of the humid air and improving moisture absorption efficiency. Furthermore, this embodiment uses multiple frustum-shaped moisture-absorbing components to achieve multi-stage drying of humid air, thereby improving the drying effect.

[0033] Based on the above embodiments, in this application embodiment, the outer peripheral surface of the inner cylinder 2 is provided with a slide rail, the slide rail extends along the axial direction of the inner cylinder 2, the moisture-absorbing component 4 is provided with a slider, the inner cylinder 2 and the moisture-absorbing component 4 are slidably connected through the slide rail and the slider, and a limiting part is provided on the outer peripheral surface of the inner cylinder 2 in an adjustable position, the limiting part is used to abut against the bottom of the moisture-absorbing component 4.

[0034] In this embodiment, the moisture-absorbing component 4 is slidably connected to the inner cylinder 2, allowing for convenient adjustment of its position on the inner cylinder 2 according to actual needs. Furthermore, the edge of the moisture-absorbing component 4 can also be slidably connected to the inner wall of the outer cylinder 1 via a slider and a slide rail. The limiting part in this embodiment is used to limit the moisture-absorbing component 4, preventing it from sliding down under gravity. This embodiment does not specifically limit the limiting part; it can be a rubber ring, which is attached to the outside of the inner cylinder 2 and abuts against the bottom of the moisture-absorbing component 4 to prevent it from sliding down. Alternatively, the limiting part can be a positioning pin, with multiple positioning holes spaced apart in the axial direction of the inner cylinder 2. After the moisture-absorbing component 4 is adjusted to the set position, the positioning pin is inserted into the positioning hole, abutting against the bottom of the moisture-absorbing component 4 to prevent it from sliding down.

[0035] Based on the above embodiments, the frustum-shaped moisture-absorbing component of this application includes an inner frustum cylinder and an outer frustum cylinder. The inner frustum cylinder is coaxially sleeved inside the outer frustum cylinder. The inner frustum cylinder has a plurality of first through holes, and the outer frustum cylinder has a plurality of second through holes. The inner frustum cylinder can rotate relative to the outer frustum cylinder so that the first through holes and the second through holes are aligned or staggered. The interior of the inner frustum cylinder is used to place moisture-absorbing material.

[0036] This application does not specifically limit the method of achieving rotation of the inner frustum relative to the outer frustum. A circular groove can be provided on the bottom surface of the outer frustum, and a slider can be provided on the bottom surface of the inner frustum. The inner and outer frustums are rotatably connected through the groove and slider. A rotating shaft is connected to the bottom of the inner frustum, extending through a through-hole in the outer frustum to the outside of the outer frustum. The rotating shaft can be manually rotated to drive the inner frustum to rotate, or a motor can be used to drive the rotating shaft to rotate the inner frustum. Rotation of the inner frustum relative to the outer frustum allows the first and second through-holes to be aligned or offset, thereby adjusting the flow rate of humid air entering the inner frustum. When drying clothes is not required, the first and second through-holes are offset, preventing the absorbing material from continuing to participate in the drying process.

[0037] Based on the above embodiments, the bottom of the outer cylinder 1 in this application embodiment is provided with a drainage pipe. If water in the moisture-absorbing material flows into the bottom of the outer cylinder 1, the drainage pipe can discharge the water from the moisture-absorbing material out of the outer cylinder 1, thereby achieving continuity and efficiency in the drying process.

[0038] Based on the above embodiments, the outer cylinder 1 in this application embodiment is equipped with a first opening door on its side wall, and the frustum-shaped moisture-absorbing component is provided with a second opening door corresponding to the first opening door on its side wall. The first and second opening doors are used to take out and put in moisture-absorbing material into the frustum-shaped moisture-absorbing component. This application embodiment facilitates user replacement of the moisture-absorbing material by providing the first and second opening doors. The first opening door can be hinged to the outer cylinder 1 via a hinge, and the second opening door can be hinged to the frustum-shaped moisture-absorbing component via a hinge.

[0039] Based on the above embodiments, this application embodiment also includes a humidity sensor, a first weighing sensor and a second weighing sensor. The humidity sensor is located at the top of the inner cylinder 2 and is used to detect air humidity. The first weighing sensor is located at the bottom of the moisture-absorbing component 4 and is used to detect the weight of the moisture-absorbing material. The second weighing sensor is located on the supporting component and is used to detect the weight of the clothing.

[0040] This embodiment of the application uses a humidity sensor to detect air humidity and a second weighing sensor to detect the weight of clothing, allowing users to easily understand the dryness of their clothes. The first weighing sensor detects the weight of the moisture-absorbing material, allowing users to easily replace the moisture-absorbing material in a timely manner.

[0041] In the closed air circulation path of the internal circulation clothing drying system, the wet items are located inside the inner cavity, while the moisture-absorbing material is located inside the outer cylinder 1. The air humidity in the outer cylinder 1 is higher than that in the inner cylinder 2. The fan 3 pushes the air upwards, into the arc-shaped cover 5, and near the arc-shaped corner 6 in the middle of the arc-shaped cover 5, it begins to turn and sink. The scientifically designed arc-shaped corner 6 can reduce the loss of kinetic energy during air turning and allow it to sink quickly under the action of gravity to the moisture-absorbing component 4. It enters the moisture-absorbing component 4 through the through hole and comes into contact with the moisture-absorbing material. It continues to sink and is accelerated downwards by the incoming airflow under the continuous push of the fan 3. At the bottom, it turns and enters the inner cylinder 2, where it continues to be directly driven by the fan 3 to dry the wet items and accelerates upwards, completing the closed air circulation. In addition, the overall structure of the internal circulation clothing drying device provided in this application can be made of lightweight materials, which can reduce the weight as much as possible while ensuring structural strength, thereby reducing the burden during handling and installation and facilitating people's daily life. An energy subsystem can also be installed within the internal circulation clothes dryer to provide power to the fan 3 and various sensors. This energy subsystem includes a rechargeable battery or can be plugged into a power source. During operation, the energy subsystem powers all components within the internal circulation clothes dryer.

The various embodiments in the specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
