The drying chamber 10 features a convenient opening and closing mechanism for easy access and placement of the cleanroom cloths. Several sets of cleanroom cloth hanging rods 30 are used to hang the cleanroom cloths for easy drying. The hot air drying zone 11 is the main area for drying the cleanroom cloths. A circulating hot air zone 15 is located on both sides and the bottom inner wall of the drying chamber 10, ensuring even distribution of hot air. The air inlet 12 is connected to the circulating hot air zone 15, serving as the channel for hot air entry. Its surface dustproof mesh 13 prevents dust from entering. An exhaust fan 16 and an electric heating mesh 19 are installed inside the air inlet 12; the exhaust fan 16 draws air in. After being heated by the electric heating mesh 19, the air is sent to the circulating hot air zone 15. The hot air outlet 14 is opened on both sides of the inner wall of the drying chamber 10 and is connected to the circulating hot air zone 15, so that the hot air can be blown evenly onto the cleanroom cloth. The threaded hole 19 is used to fix the cleanroom cloth hanging rod 30, and the threaded connector 33 of the cleanroom cloth hanging rod 30 is matched with the size of the threaded hole 19 and is threadedly connected, which facilitates installation and disassembly. Thus, the hot air circulating cleanroom cloth dryer can dry the cleanroom cloth efficiently and evenly, while maintaining a dust-free drying environment.

[0030] Furthermore, the drying oven 10 is provided with an insulation shell 17 on its outer wall.

[0036] Working principle of this hot air circulating cleanroom cloth dryer:

[0037] First, grasp the pull ring 22 on the outer edge of the door 20 to open the door 20. Hang the lint-free cloth on the lint-free cloth hanging rod 30. The anti-slip sleeve 32 on the outer wall of the main rod 31 can prevent the lint-free cloth from slipping. Then, thread the threaded connector 33 at the end of the lint-free cloth hanging rod 30 to the threaded hole 19 on the inner wall of the drying chamber 10 to fix the hanging rod. Next, close the door 20. The magnetic ring seat 23 on the contact surface of the door 20 and the drying chamber 10 will make the door close tightly to ensure airtightness.

[0038] Afterwards, the equipment is started, and the exhaust fan 16 in the air inlet 12 starts to work, drawing in air. After being heated by the electric heating grid 19, the hot air enters the circulating hot air zone 15, and then is evenly blown through the hot air outlet 14 onto the cleanroom cloth in the hot air drying zone 11 to dry the cleanroom cloth. During the drying process, the temperature in the circulating hot air zone 15 can be monitored in real time through the temperature display screen 40 on one side of the drying chamber 10, so that it can be adjusted as needed.

[0039] After drying is complete, hold the pull ring 22 again to open the door 20 and remove the dried lint-free cloth from the lint-free cloth hanging rod 30. Throughout the process, the transparent window 21 embedded in the door 20 can be used to check the drying status at any time, while the heat-insulating shell 17 on the outer wall of the drying chamber 10 can effectively reduce heat loss, improve drying efficiency, and ensure drying effect.
