Description

A ceiling-mounted air handling unit for a cleanroom Technical Field

[0001] This utility model relates to the field of cleanroom technology, specifically a ceiling-mounted ventilation unit for a cleanroom. Background Technology

[0002] Air handling units are widely used in the manufacturing industry, primarily in production workshops. They deliver cool air through ductwork to each room, enabling rapid cooling of multiple rooms simultaneously. Ceiling-mounted air handling units are a common type in workshops because their structure, suspended from the ceiling, saves space.

[0003] A search revealed a Chinese patent with publication number CN220169562U that discloses a ceiling-mounted air handling unit for a cleanroom. By utilizing shock-absorbing springs installed inside the mounting sleeve and fixing sleeve, and by using dampers installed on the outer surfaces of the mounting plate and fixing plate, the mounting frame can be buffered and protected in the vertical direction. This prevents the air handling unit from vibrating during the cooling process, which could lead to loosening or gaps at the connection between the equipment and the ventilation duct.

[0004] While the above solutions can avoid the problem of vibrations in the air handling unit during the cooling process causing loosening or gaps at the connection between the equipment and the ventilation duct, the ceiling-mounted air handling unit in the above patent is difficult to clean. Cleaning requires frequent disassembly of the dust screen, which is complicated, time-consuming, and increases labor costs. Therefore, we provide a ceiling-mounted air handling unit for cleanrooms to solve the above problems. Summary of the Invention

[0029] A limiting plate 13 is slidably connected inside the groove 12. The inside of the limiting plate 13 is fixedly connected to the outer surface of the limiting post 14. A second spring 15 is sleeved on the outer surface of the limiting post 14. The end of the second spring 15 away from the limiting plate 13 is fixedly connected to the inside of the groove 12. A dust cover 16 is fixedly connected to the inner side of the connecting block 11. The groove 12 inside the connecting block 11 allows the limiting plate 13 to slide inside the groove 12. The limiting plate 13 is installed on the groove 12 and can restrict the groove 12 to prevent it from being pulled out. The second spring 15 is installed on the groove 12 and can fix the limiting post 14 under its own elastic force to prevent the dust cover 16 from falling off due to vibration.

[0030] As shown in Figures 2 and 5, the mounting plate 10 is installed on the outer shell 1, and the outer shell 1 can be fixed to the wall by bolts, which facilitates the cooling of the cleanroom by the air handling unit. The inner wall of the outer shell 1 is provided with a sliding groove 4, and a sliding rod 5 is fixedly connected inside the sliding groove 4. The outer surface of the sliding rod 5 is slidably connected to the inside of the slider 7. The upper surface of the slider 7 is fixedly connected to the lower end of the first spring 6, and the upper end of the first spring 6 is fixedly connected to the inside of the sliding groove 4. The slider 7 can slide up and down on the sliding rod 5. The sliding rods 5 on both sides can reduce the vibration of the air handling unit body 8, which can reduce the vibration generated by the air handling unit body 8 during operation. The first springs 6 on the upper and lower sides are installed on the sliding rods 5, and the first springs 6 on the upper and lower sides can support the slider 7.

[0031] A first spring 6 is sleeved on the outer surface of the slide rod 5. The slide groove 4 inside the outer shell 1 can install the slide rod 5 and the first spring 6 inside, which can reduce the shock of the blower body 8. The inner side of the outer shell 1 is provided with an installation groove 9, which is slidably connected to the blower body 8. A slider 7 is fixedly connected to one side of the blower body 8. The installation groove 9 inside the outer shell 1 can install the blower body 8 inside it. The blower body 8 can cool the cleanroom. The sliders 7 on both sides can fix the blower body 8 to prevent it from falling off during operation.

[0032] As shown in Figures 1, 3, and 4, a fixing plate 3 is fixedly connected to one side of the outer casing 1. A booster pump 210 is fixedly connected to the upper surface of the fixing plate 3. A retractable hose 209 is fixedly connected to the air outlet of the booster pump 210. The air outlet of the retractable hose 209 is fixedly connected to the air inlet of the connecting pipe 208. The booster pump 210 can be fixed to the outer casing 1 through the fixing plate 3. When cleaning, the gas is compressed by the booster pump 210. When convenient, the gas is sprayed through the nozzle 207 to clean the dust cover 16.

[0033] A cleaning mechanism 2 is provided on the lower surface of the outer casing 1. The cleaning mechanism 2 includes a support frame 205 fixedly connected to the lower surface of the outer casing 1. A fixed frame 204 is rotatably connected to the lower end of the support frame 205. An adjusting frame 202 is rotatably connected to one side of the fixed frame 204. A first electric telescopic rod 201 is hinged to one side of the adjusting frame 202, and a second electric telescopic rod 203 is hinged to the other side of the adjusting frame 202. A mounting frame 206 is fixedly connected to the lower surface of the adjusting frame 202. A nozzle 207 is fixedly connected to the lower surface of the mounting frame 206. A connecting pipe 208 is fixedly connected to the air inlet of the nozzle 207. When the dust cover 16 is used for a long time, a large amount of dust is easily accumulated on the dust cover 16, which reduces the dust removal efficiency of the dust cover 16. When it is necessary to clean the dust cover 16, the cleaning mechanism 2 can quickly clean the dust cover 16, which is beneficial to improving the dust removal effect of the dust cover 16.

[0034] The first electric telescopic rod 201, the second electric telescopic rod 203, the telescopic hose 209, the booster pump 210, the air handling unit body 8, and the dust cover 16 in this application are all common electrical devices in the prior art, and their models or specific structures will not be described in detail in this application.

[0035] Working principle: When the blower body 8 is running continuously, dust gradually adheres to the surface of the dust cover 16, increasing airflow resistance and affecting airflow efficiency. Dust easily accumulates on the dust cover 16, affecting its dust removal efficiency. When dust is removed from the dust cover 16, the first electric telescopic rod 201 and the second electric telescopic rod 203 extend and retract alternately. Through the first electric telescopic rod 201 and the second electric telescopic rod 203 on both sides, the adjusting frame 202 can be driven to swing back and forth around the axis of the fixed frame 204. The mounting frame 206 changes angle with the swing of the adjusting frame 202, performing a fan-shaped motion trajectory. The nozzle 207 forms a horizontal sweep. The pulse jet spray covers the entire surface of the dust cover. The booster pump 210 starts to generate compressed air. The airflow passes through the retractable hose 209 and is transmitted to the connecting pipe 208. The gas is then delivered into the nozzle 207 set on the mounting bracket 206 through the connecting pipe 208. The pulse jet effectively shakes off the dust adhering to the dust cover 16. The vibration generated by the air handling unit 8 during operation is offset by the first springs 6 on both sides. The dust cover 16 can be fixed to the outer shell 1 by the limiting post 14 to prevent the dust cover 16 from falling off due to the vibration generated during operation, thus achieving the cleaning of the dust cover 16.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
