Description

Technical Field

[0001] The present application relates to the technical field of laminar flow clean hoods, and in particular to a clean air system for laminar flow clean hoods. Background Art

[0002] Laminar clean hoods are divided into vertical laminar clean hoods and horizontal laminar clean hoods. The vertical laminar clean hood forms a clean air flow layer after the clean air passes through the flow net at a certain wind speed, so that the clean air flows vertically in one direction, thereby ensuring that the high cleanliness required by the process is achieved in the working area. The installation methods of vertical laminar clean hoods include hanging type (ceiling) and floor bracket type. The floor bracket type laminar clean hood mainly includes a bracket and a cover assembly. The bracket can support the cover assembly to a certain height to meet the operation needs. The cover assembly (wind chamber assembly) has a certain area, so that a certain range of clean space can be provided.

[0003] At present, the existing laminar flow clean hood itself does not have the air purification function, and generally requires an external clean air purification system. Its assembly is troublesome, the space utilization rate is low, and it needs to be assembled and disassembled on site. The assembly and disassembly process is relatively cumbersome, and the mobility after assembly is poor, and the practicality is poor. Therefore, the utility model proposes a clean air system for a laminar flow clean hood. Utility Model Content

[0049] The present application provides an embodiment of a clean air system for a laminar clean hood. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 as well as Figure 7 .

[0050] The clean air system for the laminar clean hood in this embodiment includes: an outer shell 4, a laminar air inlet chamber 41 is arranged in the outer shell 4, the laminar air inlet chamber 41 includes a first upper cavity 411 and a first lower cavity 412, the first upper cavity 411 is provided with a first air inlet connected to the external air, and a filtering and disinfection module 1 is provided at the first air inlet; a through hole connected to the interior of the first lower cavity 412 is opened at the bottom of the first upper cavity 411, an air inlet fan 3 is installed at the through hole, and a first air outlet is opened on the side wall of the first lower cavity 412.

[0051] It should be noted that: the clean air system adopts a modular design and can be flexibly assembled. By applying it to a laminar flow clean hood, the clean air system and the laminar flow clean hood are connected as one, which can make the laminar flow clean hood structure more compact and more practical.

[0052] The above is an embodiment of a clean air system for a laminar clean hood provided in the embodiment of the present application. The following is an embodiment of a clean air system for a laminar clean hood provided in the embodiment of the present application. For details, please refer to Figures 1 to 8 .

[0053] The clean air system for the laminar clean hood in this embodiment includes: an outer shell 4, a laminar air inlet chamber 41 is arranged in the outer shell 4, the laminar air inlet chamber 41 includes a first upper cavity 411 and a first lower cavity 412, the first upper cavity 411 is provided with a first air inlet connected to the external air, and a filtering and disinfection module 1 is arranged at the first air inlet; a through hole connected to the interior of the first lower cavity 412 is opened at the bottom of the first upper cavity 411, an air inlet fan 3 is installed at the through hole, a first air outlet is opened on the side wall of the first lower cavity 412, and the filtering and disinfection module 1 includes a primary filter 11, a plasma 12, an ozone reduction net 13 and a high-efficiency filter 14 arranged in sequence along the air inlet direction.

[0054] It should be noted that: when in use, the clean air system can be directly installed on the top of the laminar clean hood, and the first air outlet can be connected to the inside of the laminar clean hood, so that the air flow can be driven by the air inlet fan 3, the air can be filtered by the primary filter 11 and the high-efficiency filter 14, the air can be disinfected by the plasma 12, and the ozone generated by the plasma 12 when working can be reduced by the ozone reduction net 13, and finally ordinary air can be converted into clean air and transported to the laminar clean hood.

[0055] An air conditioning installation cavity 42 is also provided in the housing 4, and an air conditioning assembly 2 is installed in the air conditioning installation cavity 42. It can be understood that the installation, operation and control of the air conditioning assembly 2 are independent, and do not cooperate with the air inlet fan 3 and the filtering and disinfection module 1, but the cold and hot air inside is clean air after disinfection and filtration, that is, the operation of the air conditioning system will not change the cleanliness inside the laminar clean hood, but only adjust the temperature and humidity inside the clean hood.

[0056] The air conditioning installation cavity 42 includes a second upper cavity 421 and a second lower cavity 422. The air conditioning component 2 includes a compressor 21, a first exhaust fan 22, a second exhaust fan 26, a condenser 23, an evaporator 24 and a heater 25. One side of the second upper cavity 421 is provided with a second air inlet connected to the outside air, and the other side is provided with a second air outlet connected to the outside air. The compressor 21 is arranged in the second upper cavity 421, the condenser 23 is arranged at the second air outlet, the first exhaust fan 22 is arranged on the inner side of the condenser 23, and a third air outlet for connecting to the inside of the laminar clean hood is opened at the bottom of the second lower cavity 422. The second exhaust fan 26 is arranged at the third air outlet, and a third air inlet is opened on the side wall of the second lower cavity 422. The evaporator 24 is arranged at the third air inlet, and the heater 25 is arranged on the evaporator 24.

[0057] It should be noted that: by providing a second air inlet connected to the external air on one side of the second upper cavity 421, and providing a second air outlet connected to the external air on the other side, the air path of the upper condenser 23 is circulated outside the laminar flow clean hood; by providing a third air outlet for connecting to the inside of the laminar flow clean hood at the bottom of the second lower cavity 422, and providing a third air inlet on the side wall of the second lower cavity 422, the air path of the lower evaporator 24 is circulated inside the laminar flow clean hood.

[0058] It is understandable that the third air inlet can be directly connected to the inside of the laminar clean hood, and the air in the laminar clean hood can be circulated. Preferably, the third air inlet can also be connected to the first air outlet, and the filtered and sterilized air can be directly supplied through the laminar air inlet cavity 41, so as to ensure the cleanliness of the cold air or hot air at the air outlet of the evaporator 24.

[0059] Specifically, the number of the laminar air inlet cavities 41 may be two, and the two laminar air inlet cavities 41 are symmetrically distributed on the left and right sides of the air conditioner installation cavity 42 .

[0060] The number of the first air inlets may be two, and the two first air inlets are respectively located at the front and rear sides of the first upper cavity 411, and a filtering and disinfection module 1 is provided at each first air inlet.

[0061] The filtering and disinfecting module 1 can be detachably installed at the first air inlet. Specifically, the filtering and disinfecting module 1 can be detachably installed at the first air inlet through a pull-out structure, which is convenient for maintenance and replacement.

[0062] The air inlet fan 3 is located in the first lower cavity 412 .

[0063] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
