[0027] The following will combine Figure 1-3 This application provides a detailed description of a pass-through window for transferring items between different clean areas within a cleanroom, as described in the embodiments of this application. It is important to note that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.

[0028] Example 1:

[0029] like Figure 1-3 A pass-through window for transferring items between different clean areas in a cleanroom includes: a frame 1, a blowing unit, and a return air unit. The lower part of the frame 1 is the pass-through area, and the upper part of the frame 1 is the installation area. The blowing unit is located in the installation area and is used to blow air at a preset wind speed into the pass-through area. The wind speed of the air blown into the pass-through area by the blowing unit is 18-20 m / s. The return air unit is located in the pass-through area and is used to guide the air in the pass-through area to the installation area.

[0030] A partition plate is installed in the middle of the frame 1, dividing the interior of the frame 1 into two independent transfer areas and an installation area. A main access door 5 and a secondary access door 4 are installed on the front and rear sides of the installation area, respectively. Both the main access door 5 and the secondary access door 4 are made of stainless steel and have two pieces of transparent tempered glass on them for easy observation of the items in the transfer area.

[0031] In this embodiment, the blowing unit includes: a fan 6, a high-efficiency filter 7, and an air shower nozzle 8. The fan 6 is used to deliver air through the high-efficiency filter 7 to the air shower nozzle 8. The air shower nozzle 8 is installed on the partition plate and blows air at a preset wind speed into the delivery area through the air shower nozzle 8.

[0032] In this embodiment, the return air unit includes a return air perforated plate 10, which is disposed on both sides of the transfer zone, and forms a sealed return air cavity with the side walls of the transfer zone. The top of the return air cavity communicates with the installation area, and the return air perforated plate 10 is provided with a plurality of return air holes. An ultraviolet lamp 9 is provided on the side of the return air perforated plate 10 away from the return air cavity.

[0033] When items need to be transferred, the electromagnetic lock is disengaged via the control panel 3, which opens the main passage door 5 and the auxiliary passage door 4. After the main passage door 5 is opened and the item is sent into the transfer area, it is closed. The controller then starts the fan 6. Air first passes through the high-efficiency filter 7, and then is sprayed at high speed through the air shower nozzles 8 onto the chamber, removing dust from the surface of the items. The dust-laden air enters the return air chamber through the return air vents on the return air plate 10, and is then blown into the installation area by the fan 6 to complete the circulation. Simultaneously, during the air shower process, the ultraviolet lamp 9 is turned on, emitting ultraviolet light to sterilize the surface of the items. A differential pressure gauge 2 is installed on the outside of the installation area. By observing the 500Pa differential pressure gauge 2 on the front, the high-efficiency filter 7 needs to be replaced when the specified value is reached.

[0034] This utility model is made of SUS304 stainless steel, and the inner edge of the transfer area is rounded, which has many advantages such as corrosion resistance, easy cleaning and no dust accumulation.

[0035] The cleaning and sterilization time can be set by the user. Items can only be removed from the auxiliary storage door 4 after cleaning and sterilization are completed. The fan 6 has five speed settings, and the desired airflow can be achieved by adjusting the fan 6 via the controller.

[0036] The above description is only a preferred embodiment of the present utility model and is used to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
