[0025] The following describes the specific structure of a wardrobe structure with laminar flow:

[0026] Taking Figure 1 the front view as the front end for description:

[0027] Please refer to Figures 1 to 6, the wardrobe structure with laminar flow in this embodiment includes a cabinet body 1, and the cabinet body 1 is composed of a top plate 101, a bottom plate 102, a back plate 103, a first side plate 104 and a second side plate 105. The top plate 101, the bottom plate 102, the back plate 103, the first side plate 104 and the second side plate 105 are sealed with each other by a seal 11, which improves the airtightness of the overall wardrobe. Preferably, the back plate 103 is used as an access panel and can be detachably used for maintenance.

[0028] Furthermore, the wardrobe structure further includes a filtering component, and the filtering component is arranged inside the cabinet body 1. The filtering component includes a first filter 6 and a second filter 7. Preferably, the first filter 6 is a primary filter for primarily filtering particles and microbial impurities in the air, and the second filter 7 is a high-efficiency filter for ultimately filtering particles and microbial impurities in the air.

[0029] Furthermore, a fan 3, a flow equalizing plate 4 and a box body 5 are also arranged inside the cabinet body 1. Preferably, two of the fan 3, the box body 5, the first filter 6 and the second filter 7 are provided in this embodiment. The fan 3 is arranged at the bottom end of the cabinet body 1, and the above-mentioned first filter 6 is connected to the fan 3 and arranged at the bottom end of the cabinet body 1. The wardrobe structure further includes a first plate body 10, and the first plate body 10 is arranged outside the first filter 6 for concealing the first filter 6. The first plate body 10 is also provided with a second hole 1001 that cooperates with the first filter 6. Preferably, the second hole 1001 is an air return port for the intake and suction of the fan 3.

[0030] Furthermore, a storage grid 2 is also arranged in the wardrobe structure, and the storage grid 2 is arranged between the top plate 101 and the first filter 6. A first partition 8 is arranged at the upper end of the first filter 6 near the storage grid 2. Preferably, three storage grids 2 are provided in this embodiment, and the storage grids 2 are separated from each other by a second partition 12 up and down.

[0031] Furthermore, the flow equalizing plate 4 is arranged along a first direction and cooperates with the storage grid 2. The first direction is the height direction of the wardrobe structure, and the second filter 7 is also arranged in the box body 5 along the first direction. The second filter 7 cooperates with the flow equalizing plate 4 to perform laminar air supply to the storage grid 2.

[0032] Furthermore, one end of the box body 5 away from the first filter 6 is closed. The upper end of the box body 5 is connected to the top plate 101, and a first hole 501 is opened at one end of the box body 5 near the first filter 6. By providing the first hole 501, the fan 3 can send air to the second filter 7.

[0033] Further, the wardrobe structure further includes a lamp tube 9, which is concealed on the surfaces of the first side plate 104 and the second side plate 105 and is matched with the storage compartment 2. Preferably, the lamp tube 9 is preferably an ultraviolet lamp for performing ultraviolet sterilization on the items in the storage compartment 2.

[0034] Further, a door body 13 is arranged outside the storage compartment 2 at the front end of the wardrobe structure. Preferably, the door body 13 is a double-door, which is convenient for operators to check the internal situation and prevents the influence on personnel when the lamp tube 9 is operating.

[0035] Further, a control panel 14, a relay 15 and a differential pressure gauge 16 are arranged at the front end of the top plate 101. Preferably, in this embodiment, the control panel 14 is used for equipment control to control the opening and closing of the fan 3 and the lamp tube 9, the relay 15 is used for setting the operation time of the lamp tube 9, and the differential pressure gauge 16 is used for monitoring the upstream and downstream differential pressure of the second filter 7 to provide data parameters for the replacement of the second filter 7.

[0036] Further, a first detection port 17 and a second detection port 18 are arranged on the left and right sides at the front end of the first partition 8. Preferably, the first detection port 17 and the second detection port 18 are respectively a PAO dust generation port and a PAO sampling port for the integrity detection of the second filter 7.

[0037] Further, a power supply port 19 is also arranged on the second side plate 105 for powering on the wardrobe structure.

[0038] The following describes the specific working process of a wardrobe structure with laminar flow according to an embodiment of the present invention as follows:

[0039] When the wardrobe structure is powered on, the fan 3 operates, and external air is sent into the wardrobe structure through the second hole 1001. After primary filtration by the first filter 6, it then flows through the first hole 501 to the box body 5, and then is ultimately filtered by the second filter 7 in the box body 5, and then is sent through the flow equalizing plate 4 for laminar flow to the storage compartment 2, effectively ensuring that the internal environment of the wardrobe structure can reach the sterile level.

[0040] In this embodiment, it is required that the equipment meets the requirements of Class A environmental level, that is, the sterile level;

[0041] Its specific functional data is reflected in that through the settings of the first filter 6 and the second filter 7, the number of internal environment particles can be controlled within 3250 particles / m 3 When the particle size is not greater than 0.5 μm and is controlled within 20 particles / m 3 When the particle size is not greater than 5.0 μm, the number of settled bacteria and floating bacteria is not greater than 1 cfu / m 3 .

[0042] Its air outlet wind speed can be controlled within 0.36 - 0.54 m / s, that is, 0.45 m / s ± 20%. Through the flow equalizing plate 4, it can ensure that the error of the air outlet wind speed at each point does not exceed ±20%.

[0043] When the device is in the state of controlling the wind speed, it can ensure that the air flow is a horizontal unidirectional flow, that is, the air flow comes out from the second filter 7, passes through the interior, and then discharges from the gap of the door body 13, and the air flow will not flow back or form dead corners such as vortices.

[0044] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0045] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
