[0042] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0043] In modern home life, clothes racks are not only basic tools for drying clothes, but also important facilities for improving the quality of life. With technological advancements and diversified consumer demands, the technology of clothes racks is constantly evolving, developing from a single drying function towards integration and intelligence. Especially in humid and rainy areas or seasons, drying clothes becomes a major challenge. Traditional clothes racks cannot meet the need for rapid drying; therefore, there is an urgent market demand for clothes racks with drying functions. This embodiment will detail an innovative floor-standing clothes drying device 100, which not only solves the limitations of traditional clothes racks but also provides an efficient and convenient clothes drying solution.

[0044] like Figures 1 to 3, Figure 7 As shown, a floor-standing clothes dryer 100 includes a drying unit 10, a retractable scissor rack assembly 20, and a horizontally extending clothes rack 30. This floor-standing clothes dryer 100, with its unique technology and functions, brings unprecedented convenience to users. It mainly consists of the drying unit 10, the retractable scissor rack assembly 20, and the horizontally extending clothes rack 30, each component meticulously crafted to ensure optimal performance and user experience.

[0045] The drying unit 10 is the core of the entire drying system. It includes a robust housing 11, a built-in hot airflow device 12, and a drawer-type drying chamber 13. The housing 11 not only provides a stable support structure but also protects the internal precision components. The hot airflow device 12 is located in the middle of the housing 11, with its sides used to connect to the lower end of the longitudinal scissor frame 21 and to mount the gas springs 40. This layout makes the entire device more compact while improving the utilization efficiency of the hot airflow.

[0046] The hot airflow device 12 consists of a centrifugal fan 121 and a heater 122. The centrifugal fan 121 has two airflow ports: the main airflow port f1 faces upward, and the auxiliary airflow port f2 faces horizontally. This technology allows the hot airflow to flow upward more effectively, covering the entire area of ​​the clothes rack 30, thereby achieving uniform drying.

[0047] The drawer-type drying oven 13 has an airflow inlet f3 at the back, which is connected to the secondary airflow outlet f2 via a flexible corrugated pipe 14 to ensure smooth flow of hot air. The drawer-type drying oven 13 allows it to be easily pulled out of the drying unit 10, making it convenient for users to place small items of clothing directly into the drying oven for drying.

[0048] Furthermore, it should be noted that the flexibility of the bellows 14 makes the connection more stable and can adapt to different installation angles and positions, reducing the complexity of the installation process. The heat resistance of the bellows 14 ensures long-term use in high-temperature environments, while its smooth internal surface facilitates the smooth flow of hot air, reducing energy loss during transmission.

[0049] The scissor-shaped frame assembly 20 is key to achieving height adjustment of the clothes drying rack. It consists of two parallel longitudinal scissor frames 21, with their lower ends connected to the housing 11 and their upper ends connected to the clothes drying rack 30. This technology allows the clothes drying rack to be freely adjusted between different heights to accommodate the different heights and drying needs of users. Hot airflow generated by the hot airflow device 12 flows upwards across the clothes drying rack 30, ensuring that clothes are dried evenly at any height. To drive the longitudinal scissor frames 21 to extend and retract in the vertical direction, the device also includes two gas springs 40. The telescopic end of each gas spring 40 is connected to the lower end of its respective longitudinal scissor frame 21. By manually controlling the extension and retraction of the gas springs 40, the height of the clothes drying rack 30 can be easily adjusted. This technology not only improves the ease of operation but also makes the entire device more stable and durable.

[0050] The clothes rack 30 is the drying platform of the entire device, comprising a main clothes rack 31 and auxiliary clothes racks 32 connected to both sides of the main clothes rack 31. The auxiliary clothes racks 32 can extend or retract laterally, providing additional drying space, especially suitable for drying large items or in situations requiring more space. The main clothes rack 31 consists of two main poles 311 and multiple spaced-apart drying support poles 312, while the auxiliary clothes rack 32 consists of retractable auxiliary poles 321 and multiple spaced-apart drying support poles 322. This technology not only improves the load-bearing capacity of the clothes rack but also ensures ventilation between clothes, accelerating the drying process.

[0051] like Figures 1 to 3 As shown, in the unfolded state, the longitudinal scissor bracket 21 unfolds upwards, raising the clothes rack 30 to the target height for easy hanging and retrieving of clothes. Figure 7 As shown, in the storage state, the longitudinal scissor bracket 21 folds downward, causing the clothes rack 30 to fall onto the upper side of the housing 11. The cross-sectional area of ​​the clothes rack 30 is less than or equal to the cross-sectional area of ​​the housing 11, which greatly saves space and makes it convenient for users to store it when not in use.

[0052] This floor-standing clothes dryer's technology fully considers the needs for stability and flexibility. Two parallel longitudinal scissor arms 21 are height-adjustable via gas springs 40. This technology not only improves ease of operation but also makes the entire device more stable and durable.

[0053] In addition, such as Figures 4 to 6 As shown, the telescopic end of the gas spring 40 is connected to the first slider k1 via the connecting rod 41. When the first slider k1 slides, it can drive the second slider k2 to move in the opposite or relative direction. This technique ensures the smooth unfolding and retraction of the longitudinal scissor frame 21.

[0054] Furthermore, the technology of the clothes rack 30 fully considers the diverse needs of users. The main clothes rack 31 and the secondary clothes rack 32 provide ample drying space, making them particularly suitable for drying large items of clothing or in situations requiring more space. The extendable technology of the secondary clothes rack 32 allows users to adjust the width of the clothes rack according to their actual needs. This technology not only improves the practicality of the clothes rack but also saves space.

[0055] More specifically, such as Figure 2 and Figure 4 As shown, the lower end of the longitudinal scissor frame 21 includes a first slider k1, a first intermediate end k2, and a second slider k3. The housing 11 contains a first slide rail h1 for the lower end of the longitudinal scissor frame 21 to move. The first intermediate end k2 is axially connected to the first slide rail h1, and the first slider k1 and the second slider k2 can slide on the first slide rail h1. This technique not only enhances the stability of the structure but also provides flexible sliding functionality. The housing 11 is internally designed with a first slide rail h1, which serves as the track for the lower end of the longitudinal scissor frame 21 to move, ensuring the smoothness and precision of the sliding process. The first intermediate end k2 is fixed to the first slide rail h1 via an axial connection, while the first slider k1 and the second slider k2 can slide freely on the first slide rail h1. This technique allows for precise height adjustment of the longitudinal scissor frame 21 in the vertical direction.

[0056] The telescopic end of the gas spring 40 is connected to the first slider k1 via a connecting rod 41. This connection method allows the telescopic action of the gas spring 40 to be directly converted into the unfolding and retracting action of the longitudinal scissor frame 21. When the first slider k1 slides along the first slide rail h1, it can drive the second slider k2 to move in the opposite or relative direction. This synchronous sliding mechanism ensures the smooth unfolding and retracting of the longitudinal scissor frame 21, and also ensures the stability of the clothes rack 30 when adjusting its height.

[0057] At the upper end of the longitudinal scissor frame 21, a third slider k4, a second intermediate end k5, and a fourth slider k6 are provided. Below the main rods 311 on both sides of the clothes rack 30, a second slide rail h2 is provided, which serves as the track for the upper end of the longitudinal scissor frame 21 to move. The second intermediate end k5 is pivotally connected to the second slide rail h2, while the third slider k4 and the fourth slider k6 can slide on the second slide rail h2. This technique allows for precise horizontal position adjustment of the clothes rack 30.

[0058] To enhance the stability of the longitudinal scissor frame 21, a first slider k1 is connected to a first support rod c1, and a second slider k2 is connected to a second support rod c2. A third support rod c3 is pivotally connected to the middle section of the first and second supports, and the two third support rods c3 are pivotally connected to the first slide rail h1 via pins. This structural design not only enhances the stability of the longitudinal scissor frame 21 but also improves its load-bearing capacity. Similarly, a third slider k3 is connected to a fourth support rod c4, and a fourth slider k4 is connected to a fifth support rod c5. A sixth support rod c6 is pivotally connected to the middle section of the third and fourth supports, and the two sixth support rods are pivotally connected to the second slide rail h2 via pins, further enhancing the stability and durability of the longitudinal scissor frame 21.

[0059] Finally, it should be noted that the floor-standing design in this embodiment allows the device to be flexibly placed anywhere indoors without the need for fixed installation. It is both stable and easy to maintain, making it particularly suitable for renters or users who do not wish to make permanent modifications to their homes. Meanwhile, the drawer-type drying oven design provides a convenient solution for drying small items of clothing. Its rear airflow inlet is connected to a hot airflow device, ensuring smooth flow of hot air and achieving rapid and even drying of clothes.

[0060] Combining the flexibility of a floor-standing design with the high-efficiency drying performance of a drawer-type drying oven, this clothes drying device provides users with a space-saving and easy-to-use clothes drying solution. It not only improves drying efficiency but also enhances the user experience, making the drying process more comfortable and convenient, perfectly suited to today's fast-paced lifestyle.
