Description

Technical Field

[0001] The utility model relates to the technical field of transfer windows, in particular to a novel transfer window. Background Art

[0002] As an auxiliary equipment of clean room, transfer window is mainly used for transferring small items between clean area and clean area, and between non-clean area and clean area, so as to reduce the number of times the clean room door is opened and minimize the pollution of clean area.

[0003] In the utility model with Chinese patent publication number CN205823082U, a transfer window is proposed. The transfer window takes pictures through a camera inside the box and the controller determines whether there is an object in the box in combination with the position of the sender. If there is an object, the flashing light on the door leaf where the recipient is located will give a reminder. The staff can turn on the display to observe the status of the object and open the door leaf to take out the object. Due to the restriction of the interlocking device, only one door leaf can be opened, thereby avoiding the cabinet doors on both sides of the transfer window from being opened at the same time and reminding the staff to take out the items. However, the filtering effect and the uniform air outlet effect of the transfer window need to be improved. Therefore, the utility model proposes a new transfer window. Utility Model Content
