Description

Technical Field

[0001] This utility model relates to a self-cleaning laminar flow transfer window for clean rooms that is easy to assemble. Background Technology

[0002] The cleanroom self-cleaning laminar flow pass-through window is a device used for transferring items between cleanrooms or between a cleanroom and a non-cleanroom. Its core principle is to prevent cross-contamination of pollutants during transfer through directional airflow purification and pressure control. The pass-through window has a built-in high-efficiency particulate air (HEPA) filter. A fan draws in internal air, which is then filtered into clean air. This clean air is finally blown out in laminar flow (parallel, stable, and vortex-free airflow) from the flow equalization plate at the top of the pass-through chamber, covering the entire transfer space. In addition, internal germicidal lamps release ultraviolet light to sterilize the inside of the pass-through window and the surfaces of the transferred items. Residual contaminants on the surfaces of the transferred items are then drawn into the filter at the top by the fan through the mesh on the side of the pass-through chamber, and this process is repeated.

[0003] The pass-through window enclosure consists of an outer shell, an inner liner, and left and right side door frames. A closed cavity is formed between the inner liner, outer shell, and door frames. A filter and a fan are installed within this cavity, and the fan circulates airflow between the inner liner and the cavity. Pass-through windows require a high degree of airtightness. Previously, the inner liner and outer shell were mostly connected by welding sheet metal, resulting in numerous weld points and seams. Excessive welding can deform the sheet metal, affecting the enclosure's airtightness. Furthermore, the greater the welding workload, the lower the overall production efficiency of the enclosure.
