Description

Technical Field

[0001] The invention belongs to the technical field of air coolers, in particular to an air cooler for a vertical quick-freezing cabinet. Background Art

[0002] Vertical quick freezer is a device that provides cold air to goods, so that goods and other items are stored at low temperatures, ensuring that goods and other items remain cold, thereby extending their shelf life. The vertical quick freezer cools them through air coolers, so that the interior of the vertical quick freezer is in a low-temperature environment. When the air cooler is running, the fan blades on the axial flow fan rotate to absorb the heat of the goods in the vertical quick freezer into the air cooler, and then after being processed by the radiator in the air cooler and dissipated, it becomes cold air and is discharged from the cold air outlets on both sides of the air cooler into the vertical quick freezer to cool the goods.

[0003] In the prior art, when an axial flow fan blows external hot air to the radiator, a circular filter is installed on the back of the fan blade to prevent dust from entering. The dust can be filtered. However, since the circular filter is installed inside the air cooler, a lot of dust will adhere to the surface of the circular filter facing the fan blade after being used for a long time. This dust will affect the entry of external hot air. Generally, a person will open the air cooler and then clean the dust on the surface of the circular filter inside the air cooler. Moreover, when a lot of dust adheres to the surface of the fan blade, it also needs to be cleaned manually, which not only increases the workload of the personnel, but also reduces the efficiency of dust cleaning.

[0021] Embodiment 2 Based on Example 1, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8The fixed cleaning component includes a long block 215 and a fixed rod 214 fixed at the end of the long block 215. Two groups of vertical brushes 204 are slidably arranged on the outside of the long block 215. The dust on the surface of the fan blade 103 can be cleaned by moving the two groups of vertical brushes 204 in opposite directions. A double-headed cylinder 216 is fixedly arranged at the bottom of the long block 215.

A fixed block 213 is fixedly arranged on the outside of the pillar 205.

[0022] The cleaning mechanism of the present invention is designed. When a lot of dust adheres to the surface of the circular filter 106 located inside the casing 100, the driving motor 200 drives the rotating rod 201 to rotate, thereby driving the horizontal brush 207 to rotate to clean the dust adhered to the surface of the circular filter 106. By turning on the double-headed cylinder 216, the two sets of vertical brushes 204 move in opposite directions to contact the surface of the fan blade 103, and then the axial flow fan is turned on. At this time, the fan blade 103 rotates. During the rotation process, the dust adhered to the surface of the fan blade 103 is cleaned by the vertical brush 204, thereby realizing automatic cleaning of the dust on the surface of the circular filter 106 and the fan blade 103, improving the cleaning efficiency and reducing the labor of personnel.

[0023] During use, when cleaning the dust attached to the surface of the circular filter 106, the driving motor 200 is started to drive the rotating rod 201 to rotate, and then the first bevel gear 209 on the rotating rod 201 drives the second bevel gear 210 on the cross bar 202 to rotate, thereby driving the cross bar 202 to rotate, and then the worm 211 on the cross bar 202 drives the worm wheel 212 to rotate, thereby driving the mounting column 208 and the cross brush 207 to rotate, at this time, the dust attached to the surface of the circular filter 106 can be cleaned by the rotation of the cross brush 207, and the axial flow motor 105 on the axial flow fan is reversed during the cleaning process, so that the fan blades 103 are reversed, and the wind is discharged outward at this time, which can discharge the dust generated during the cleaning process outward; When cleaning the dust attached to the surface of the fan blade 103, first stop the rotation of the fan blade 103, then start the double-headed cylinder 216, and the working ends of the double-headed cylinder 216 move in opposite directions, driving the vertical brush 204 to move. At this time, the vertical brush 204 slides on the long block 215, and then the vertical brush 204 contacts the surface of the fan blade 103. At this time, turn on the axial flow motor 105, reverse the working end of the axial flow motor 105, and drive the fan blade 103 to reverse. During the rotation process, the vertical brush 204 can clean the dust on the surface of the fan blade 103, and the dust generated during the cleaning process can be discharged outward through the reversal of the fan blade 103, thereby cleaning the dust attached to the surface of the fan blade 103.

[0024] Embodiment 3 Based on Example 2, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , three groups of flipping parts for flipping the vertical brush 204 are arranged inside the housing 100, and the flipping parts include a bottom plate 400 fixed inside the housing 100 and a driven circle 217 sleeved and fixed outside the fixed rod 214, and a mounting motor 401 is fixedly arranged on the top of the bottom plate 400, and the vertical brush 204 can be driven to flip by the mounting motor 401, and an active circle 403 is sleeved and fixed on the working end of the mounting motor 401, and a transmission belt 404 is sleeved between the active circle 403 and the driven circle 217, and the fixed rod 214, the long block 215, and the vertical brush 204 can be driven to rotate through the transmission belt 404 to realize flipping, and the fixed rod 214 and the fixed block 213 are rotatably connected through a rotating shaft; A mounting plate 402 is also fixedly provided on the top of the base plate 400, and a hydraulic rod 406 is fixedly provided on the surface of the mounting plate 402. The hydraulic rod 406 can push the arc plate 407 and the friction plate 405 to move toward the active ring 403. The working end of the hydraulic rod 406 is fixedly provided with the arc plate 407, and the inner wall of the arc plate 407 is fixedly provided with the friction plate 405.

[0025] The present invention uses a designed flip piece, when there is no need to clean the dust on the fan blade 103, to start the installed motor 401 and drive the transmission belt 404 to rotate, thereby driving the vertical brush 204 to flip downward at a certain angle to a tilted state, which can maximize the reduction of the influence of the vertical brush 204 on the air volume entering the casing 100 during use, avoid the influence of the vertical brush 204 in the vertical state on the air volume entering the casing 100, and improve the use effect.

[0026] When the fan blade 103 does not need to be cleaned of dust, the motor 401 is started to drive the active circle 403 to rotate, driving the transmission belt 404 to rotate, and then driving the driven circle 217 and the fixed rod 214 to rotate, and then driving the long block 215 to rotate, and then driving the vertical brush 204 to rotate. When it rotates to a certain angle, it stops. At this time, the vertical brush 204 rotates downward to a certain angle, and the vertical brush 204 is in an inclined state. Then the hydraulic rod 406 is started, and then the arc plate 407 is driven to move toward the active circle 403. Then the friction plate 405 on the arc plate 407 contacts and clamps the active circle 403, which can increase the stability of the vertical brush 204 after tilting and reduce the influence of the vertical brush 204 on the air volume entering the casing 100 during use. When it is necessary to clean the dust on the surface of the fan blade 103, the above-mentioned opposite principle is used to operate, and the vertical brush 204 is in a vertical state for cleaning.

[0027] Embodiment 4 Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.11 A limiting member is provided on the top of the housing 100 for clamping and limiting the rotating rod 201. The limiting member includes a fixing ring 301 sleeved and fixed on the outside of the rotating rod 201 and a vertical plate 300 fixed on the top of the housing 100. The outer wall of the fixing ring 301 is provided with multiple groups of limiting holes 302. The rotating rod 201 is limited by inserting the plug posts on the moving frame 303 into the limiting holes 302. The moving frame 303 is slidably provided inside the vertical plate 300. The end of the moving frame 303 is fixedly provided with a plug post for inserting into the limiting holes 302 to limit the rotating rod 201. The outer part of the mobile frame 303 is fixedly provided with a concave limiting plate 307, which can play a certain limiting effect on the mobile frame 303, reducing the probability of the end of the mobile frame 303 being separated from the vertical plate 300. The upper surface of the mobile frame 303 is provided with two groups of sockets 308, and the interior of the vertical plate 300 is slidably provided with two groups of plug rods 304, and the bottom of the plug rod 304 is inserted into the interior of the socket 308; A top plate 305 is fixed on the top of the insertion rod 304, and an elastic band 306 is fixed between the top plate 305 and the vertical plate 300. The elastic band 306 can ensure that the bottom of the insertion rod 304 can always be inserted into the socket 308 on the movable frame 303, thereby increasing the stability of the insertion column into the limit hole 302.

[0028] The present invention has a designed limiter. When the dust on the circular filter 106 is not cleaned, the end of the plug post on the movable frame 303 is inserted into the corresponding limit hole 302 in the fixed ring 301 to limit the rotating rod 201, thereby preventing the fan blade 103 from rotating and sucking external hot air into the interior of the casing 100 or accidentally hitting the rotating rod 201, causing the rotating rod 201 to rotate and causing the horizontal brush 207 to rotate, thereby facilitating use.

[0029] When the dust on the circular filter screen 106 is not cleaned, the top plate 305 is moved upward to drive the insertion rod 304 to move. At this time, the elastic band 306 is stretched, and then the bottom of the insertion rod 304 is separated from the surface of the movable frame 303. At this time, check whether the position of the limit hole 302 is correct. If it is not correct, start the drive motor 200 to drive the rotating rod 201 to rotate, so that the limit hole 302 on the fixing ring 301 is consistent with the position of the end of the subsequent insertion column inserted into the limit hole 302. At this time, the movable frame 303 located near the left side of the vertical plate 300 is moved away from the fixing ring 3 01 direction, driving the plug column to move, and then moving the movable frame 303 to the right direction, driving the plug column to move. When the end of the plug column is aligned with the corresponding limiting hole 302 on the fixing ring 301, the movable frame 303 is moved in the direction close to the fixing ring 301, and then the end of the plug column is inserted into the corresponding limiting hole 302. At this time, it can be limited to prevent the fan blade 103 from rotating and sucking external hot air and hot wind into the interior of the casing 100, or accidentally hitting the rotating rod 201, causing the rotating rod 201 to rotate, causing the horizontal brush 207 to rotate.

[0030] In this embodiment, three groups of brackets 102 are fixedly provided on the casing 100 for fixing the axial flow motor 105. Three groups of inlet rings 104 are embedded and installed inside the casing 100. A heat exchanger 107 is provided inside the casing 100 for cooling the hot air entering the casing 100. Cold air outlets 101 are fixedly provided on both sides of the casing 100.

[0031] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
