[0035] Embodiment

[0036] Please refer to Figure 1 The present embodiment provides a wind and sand prevention cabinet air conditioner, in particular to a simple and efficient wind and sand prevention cabinet air conditioner. The wind and sand prevention cabinet air conditioner comprises an air conditioner body 100, a filter screen 200 and an air inlet pipe 300.

[0037] Among them, the air conditioner body 100 has an air inlet 110. Correspondingly, the filter screen 200 is arranged on the air conditioner body 100, and the filter screen 200 covers the air inlet 110.

[0038] In addition, one end of the air inlet pipe 300 surrounds the filter screen 200 and is connected with the air conditioner body 100. The other end of the air inlet pipe 300 is arranged downwardly.

[0039] When the sand-proof cabinet air conditioner works, the air in the external environment first enters the air inlet pipe 300, and then flows into the air inlet 110 on the air conditioner body 100 after being filtered by the filter screen 200. In areas with more wind and sand, there is often a horizontal airflow around the air conditioner body 100. Since the end of the air inlet pipe 300 away from the air conditioner body 100 is bent downward, the horizontal airflow needs to be diverted before flowing upward into the air inlet pipe 300 and being diverted again at the bent part of the air inlet pipe 300. In the process of diversion, the large particles of dust mixed in the airflow are separated from the airflow due to inertia, thereby effectively reducing the dust content in the airflow flowing through the filter screen 200, preventing the filter screen 200 from being easily clogged and avoiding affecting the normal operation of the air conditioner body 100, and without the need for frequent cleaning of the filter screen 200, the use is more convenient.

[0040] In some embodiments, the filter screen 200 is detachably connected with the air conditioner body 100.

[0041] During the filtering of dust in the air by the filter screen 200, part of the dust will adhere to the filter screen 200, and the maintenance personnel need to clean the filter screen 200 regularly. By detachably connecting the filter screen 200 with the air conditioner body 100, the maintenance personnel can detach the filter from the air conditioner body 100 when cleaning the filter screen 200, thereby facilitating cleaning.

[0042] Please refer to Figure 2 Specifically, the filter screen 200 includes a filter screen body 210 and an outer frame 220. The outer frame 220 surrounds the filter screen body 210, and the outer frame 220 is detachably connected with the air conditioner body 100.

[0043] In use, the filter screen body 210 plays a role in filtering dust in the air, and the outer frame 220 fixes and supports the filter screen body 210.

[0044] In some embodiments, the outer frame 220 is provided with a magnetic attraction piece 221, and the magnetic attraction piece 221 is magnetically attracted to the air conditioner body 100.

[0045] In use, the maintenance personnel only need to overcome the magnetic attraction between the magnetic attraction piece 221 and the air conditioner body 100 to detach the outer frame 220 from the air conditioner body 100. After the cleaning of the filter screen 200 is completed, the maintenance personnel attaches the outer frame 220 to the surface of the air conditioner body 100 again, so as to fix the outer frame 220 on the air conditioner body 100, and the detachment and assembly process is convenient and fast.

[0046] Exemplarily, the outer frame 220 is square-shaped, and a magnetic attraction strip is arranged on each of the four edges of the outer frame 220. The magnetic attraction strip serves as the magnetic attraction piece 221 and is magnetically attracted to the steel shell of the air conditioner body 100.

[0047] In some embodiments, the outer frame 220 is provided with a screw hole, and a screw is screwed into the screw hole and is screwed with the outer shell of the air conditioner body 100, so as to achieve detachable connection between the outer frame 220 and the air conditioner body 100.

[0048] Please refer to Figure 1 and Figure 3 In some embodiments, the air inlet 110 is located on the side of the air conditioner body 100. Accordingly, the air inlet pipe 300 comprises a horizontal section 310, a bending section 320 and a vertical section 330 connected in sequence. The horizontal section 310 is connected with the air conditioner body 100 and surrounds the filter screen 200 at the end away from the bending section 320.

[0049] When the windproof and sandproof cabinet air conditioner works, the horizontally flowing air flow is turned upward into the vertical section 330, is turned again in the bending section 320, and then flows in the horizontal section 310 in the horizontal direction, and finally flows into the air inlet 110 through the filter screen 200.

[0050] In some embodiments, the air inlet pipe 300 is provided with a dismounting hole 311 through which the filter screen 200 passes at the pipe wall near one end of the air conditioner body 100. In addition, the air inlet pipe 300 is further provided with a dismounting plate 340. The dismounting plate 340 is detachably connected with the air inlet pipe 300, and the dismounting plate 340 is used to shield the dismounting hole 311.

[0051] Before dismounting the filter screen 200, the maintenance personnel dismounts the dismounting plate 340 on the air inlet pipe 300 to expose the dismounting hole 311, so that the filter screen 200 can be taken out through the dismounting hole 311, without the need to dismount the entire air inlet pipe 300 from the air conditioner body 100, which is more convenient.

[0052] After dismounting the filter screen 200, the maintenance personnel installs the dismounting plate 340 again to shield the dismounting hole 311, so as to avoid that the air in the external environment directly enters the inside of the air inlet pipe 300 through the dismounting hole 311.

[0053] Specifically, the dismounting hole 311 is arranged on the pipe wall of the horizontal section 310 near one end of the air conditioner body 100, and the dismounting plate 340 is detachably connected with the horizontal section 310.

[0054] In some embodiments, the dismounting plate 340 comprises a first plate body 341 and a second plate body 342 connected with each other. The first plate body 341 is used to shield the dismounting hole 311. The second plate body 342 is arranged in pairs at both ends of the first plate body 341 and clamps both sides of the air inlet pipe 300, and the second plate body 342 is detachably connected with the air inlet pipe 300.

[0055] Specifically, the horizontal section 310 is a square tube, and the dismounting hole 311 is arranged on one of the side walls of the horizontal section 310. Meanwhile, the first plate body 341 is arranged vertically and is attached to the side wall of the horizontal section 310 on which the dismounting hole 311 is arranged. The second plate bodies 342 are arranged horizontally, one of which is attached to the top surface of the horizontal section 310, and the other of which is attached to the bottom surface of the horizontal section 310.

[0056] In addition, screws are arranged on the two second plate bodies 342 respectively, and the screws are screwed with the horizontal section 310. One of the second plate bodies 342 is detachably connected to the top surface of the horizontal section 310 through the screw, and the other of the second plate bodies 342 is detachably connected to the bottom surface of the horizontal section 310 through the screw.

[0057] In use, the maintenance personnel dismounts and mounts the dismounting plate 340 by screwing the screws.

[0058] Further, the dismounting plate 340 is slidably connected to the air inlet pipe 300 along the axial direction of the air inlet pipe 300.

[0059] Specifically, the dismounting plate 340 is slidably connected to the horizontal section 310 along the axial direction of the horizontal section 310. After the maintenance personnel unscrews the screws connecting the second plate bodies 342 and the horizontal section 310, the dismounting plate 340 does not need to be completely removed from the horizontal section 310, but can be slid in a direction away from the air conditioner body 100, so as to expose the dismounting hole 311.

[0060] Further, the dismounting plate 340 further comprises a third plate body 343. The third plate body 343 is perpendicular to the first plate body 341, and the third plate body 343 is connected to the end of the first plate body 341 away from the air conditioner body 100.

[0061] In use, the third plate body 343 can be gripped by the maintenance personnel, so that the maintenance personnel can slide the dismounting plate 340, and the operation is more convenient.

[0062] In summary, when the wind-sand-proof cabinet air conditioner works, the air in the external environment first enters the air inlet pipe 300, and then flows into the air inlet 110 on the air conditioner body 100 after being filtered by the filter screen 200. In the area where the wind and sand are relatively large, there is often a horizontal airflow around the air conditioner body 100. Since the end of the air inlet pipe 300 away from the air conditioner body 100 is arranged to be bent downward, the horizontal airflow needs to be turned before flowing upward into the air inlet pipe 300, and is turned again at the bent part of the air inlet pipe 300. In the turning process, the large particles of dust mixed in the airflow are separated from the airflow due to inertia, so that the dust content in the airflow flowing through the filter screen 200 can be effectively reduced, the filter screen 200 is not easy to be blocked, the normal operation of the air conditioner body 100 is avoided, and the filter screen 200 does not need to be cleaned frequently, which is more convenient to use.

[0063] In addition, when the filter screen 200 is cleaned, the maintenance personnel can directly pull out the filter screen 200 for cleaning by disassembling the disassembly plate 340.

[0064] The embodiment also provides an electrical control cabinet, comprising the above-mentioned sand-proof cabinet air conditioner.

[0065] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not limiting, and thus other examples of the example embodiments can have different values.

[0066] It should be noted that like reference numerals and letters refer to like items throughout the several views, and once an item is defined in one view, it need not be further defined and explained in subsequent views.

[0067] The above-described embodiments only express several implementation manners of the utility model, and the description is relatively specific and detailed, but it should not be understood as the limitation of the scope of the utility model. It should be pointed out that for ordinary skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
