Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold storage fan technology, and more specifically to a fan for pre-cooling storage. Background Technology
[0002] Cold storage precooling is a simple and practical precooling method. It involves spreading fruits and vegetables in a precooling room to cool them down as quickly as possible. Precooling methods often involve airing them out in the shade or increasing the configuration of cold storage units and fans. Fans are an important component of the precooling room. By blowing cold air to different parts of the cold storage, the temperature in different parts of the cold storage can be kept uniform, thus ensuring the refrigeration effect of the cold storage.
[0003] However, in actual use, as the usage time increases, frost will inevitably appear on the surface of the fan. If the frost is not cleaned for a long time, it will easily affect the normal use of the fan. Therefore, it is necessary to clean the frost regularly. The existing technology uses manual cleaning, which is time-consuming, labor-intensive and wastes human resources. Therefore, there is a need for a fan that can automatically remove the frost that condenses on the surface. Utility Model Content
[0004] This utility model provides a fan for a pre-cooling warehouse, which has the advantage of automatically removing frost that condenses on the surface.
[0005] A pre-cooling warehouse fan includes a frame on which a fan body is rotatably connected. The fan body contains two first motors, each with a circular disc fixed to its output shaft. Each circular disc is connected to a transmission unit, and each transmission unit is fixed with a blowing fan. A collection box and a heating unit are also connected to the fan body.
[0006] The collection box has an inclined panel inside, which is a slope that is higher on the left and lower on the right.
[0007] Each collection box is fixed with two connecting strips, each with a threaded hole. The two connecting strips can be detachably connected to the fan body by screwing bolts into the threaded holes.
[0008] The heating element is an electric heating plate.
[0009] The heating element is a plate heat exchanger containing internal fluid. Attached Figure Description

[0016] Figure 7 This is a schematic diagram of the structure of a blower. Detailed Implementation
[0017] like Figure 1-5 As shown:
[0018] The device includes a mounting frame 401, on which a fan body 101 is rotatably connected via bearings. The fan body 101 contains two first motors, and the output shafts of the two first motors are respectively fixed to two transmission parts 302 via couplings. Each transmission part 302 is fixed to a blowing fan 301 via bolts. A collection box 201 is connected to the fan body 101, and a heating part 502 is fixed to the fan body 101 via bolts.
[0019] In actual use, by rotating the blower body 101 on the mounting frame 401, the two blowing fans 301 are rotated to a suitable angle to meet subsequent blowing requirements. When blowing is needed, the two first motors can be operated to rotate, causing the two discs to rotate, which in turn causes the two transmission units 302 to drive the two blowing fans 301 to rotate, thus ensuring efficient and uniform airflow within the cold storage, thereby maintaining the cold storage effect. After a period of use, the side of the blower body 101 equipped with the blowing fans 301 can be rotated to face... The fan tilts upwards, and then the heating unit 502 is activated. This causes the heating unit 502 to melt the frost remaining on the blower 301 and the fan body 101 into water. The frost then slowly slides down the tilted fan body 101, and the water gradually enters the collection box 201, thus automatically removing the condensed frost and achieving an automatic defrosting effect. This prevents frost accumulation from affecting the normal operation of the fan body 101. The collection box 201 can temporarily store the water, making it easier to collect it later and providing convenience for subsequent operations.
[0020] Example 1: Using the heating element 502 to melt the retained frost into a watery state:
[0021] The heating part 502 is an electric heating plate. By energizing the electric heating plate, heat is generated to melt the remaining frost.
[0022] Example 2: The frost retained using the heating element 502 is melted into a watery state.
[0023] The heating unit 502 is a plate heat exchanger in which a hot fluid can flow. By circulating and heating the fluid, the plate heat exchanger can continuously and evenly generate heat, thereby melting the remaining frost.
[0024] like Figure 3-4 As shown:
[0025] The collection box 201 has an interior sloping panel 202, which is a sloped surface that is higher on the left and lower on the right. In actual use, the collection box 201 also has a baffle on the front side to prevent water from flowing out. Figure 3-4 To facilitate viewing of the sloping panel 202 structure, the front of the collection box 201 is made transparent. That is, the collection box 201 is actually an open container that is closed on all sides and bottom, with only an opening on the top, to ensure the effective collection of water and prevent water from flowing out.
[0026] After water flows into the collection tank 201, the water will naturally flow along the inclined panel 202 to the right for storage, thereby guiding the water falling into the collection tank 201 and facilitating subsequent unified water storage operations.
[0027] like Figure 3-4 As shown:
[0028] Each collection box 201 is fixed with two connecting strips 203, and each connecting strip 203 is provided with a connecting thread hole. The two connecting strips 203 can be detachably connected to the fan body 101 by screwing bolts into the connecting thread hole.
[0029] When too much water accumulates in the collection box 201, the collection box 201 can be removed from the fan body 101 by loosening the bolts in the two connecting threaded holes, so that the water stored in the inclined panel 202 can be treated uniformly, thus supporting the long-term maintenance of the water collection effect of the collection box 201.
[0030] like Figure 5-7 As shown:
[0031] The connecting threaded hole has multiple holes.
[0032] The multiple threaded holes allow for the use of more bolts to secure the two connecting strips 203, thus ensuring that the collection box 201 can be more stably connected to the underside of the fan body 101.
[0033] like Figure 3 As shown:
[0034] The main body 101 of the fan is provided with two rounded chamfers 102, and the two rounded chamfers 102 are respectively located at the corresponding positions of the two blowing fans 301.
[0035] The two rounded chamfers 102 allow the frost on the blower 301 to melt into water, which then flows downwards. This allows the water to flow smoothly along the rounded chamfers 102 to the surface of the blower body 101, facilitating its subsequent entry into the collection box 201 for temporary storage.
[0036] like Figure 5-6 As shown:
[0037] It also includes an L-shaped plate 501, which has a fixing threaded hole. The L-shaped plate 501 can be detachably connected to the fan body 101 by screwing a bolt into the fixing threaded hole.
[0038] A heating element 502 is fixedly connected inside the L-shaped plate 501. The heating element 502 is installed on the fan body 101 through the L-shaped plate 501 and is used to heat and melt the frost on the blower 301 and the fan body 101.
[0039] The fixed threaded hole allows the L-shaped plate 501 to be detachably connected to the fan body 101. In the event of a subsequent failure of the heating element 502 or when it is necessary to periodically disassemble the two blowers 301 for manual defrosting, the L-shaped plate 501 can be disassembled by loosening the bolts in the fixed threaded hole, thereby completing the above operations.
[0040] As shown in 5:
[0041] The fixed threaded hole is provided in multiple ways.
[0042] The multiple fixed threaded holes provide a more reliable connection between the L-shaped plate 501 and the fan body 101 when they are connected to each other, ensuring stable operation of the equipment.
[0043] like Figure 3 and Figure 7 As shown:
[0044] Both of the transmission units 302 are detachably connected to the circular plate inside the fan body 101 by bolts.
[0045] When the automatic defrosting function alone is insufficient to achieve the defrosting effect, the two transmission parts 302 can be disassembled by loosening the bolts of multiple fixed transmission parts 302, and then the two blowing fans 301 can be manually defrosted, thereby further maintaining the stable operation of the equipment for a longer period of time.
[0046] like Figure 5 As shown:
[0047] It also includes a second motor 402 that is bolted to the mounting frame 401. A cylindrical rod is welded to the fan body 101. The output shaft of the second motor 402 is fixed to the cylindrical rod through a coupling, thereby driving the fan body 101 to rotate.
[0048] When it is necessary to rotate the fan body 101, the second motor 402 can be started to rotate the output shaft of the second motor 402, thereby driving the fan body 101 to rotate, thus changing the orientation of the fan body 101, thereby meeting the air blowing requirements of the cold storage and facilitating subsequent defrosting operations.
[0049] Example 1: Using the second motor 402 to drive the fan body 101 to rotate;
[0050] The second motor 402 is a worm gear reducer motor. Through the perpendicular meshing structure of the worm and worm wheel, the helix angle of the worm and the tooth profile of the worm wheel form a mechanical self-locking mechanism. When the motor stops running, the worm wheel cannot drive the worm in the reverse direction, thus achieving pure mechanical self-locking. This ensures that after the fan body 101 is rotated, it can maintain the angle and achieve the effect of stably changing the orientation of the fan body 101.
[0051] Embodiment 2: The fan body 101 is driven to rotate using the second motor 402;
[0052] The second motor 402 is a motor with an electromagnetic brake. When the power is off, the brake clamps the rotating shaft, thereby locking the output shaft of the motor after rotation. This locks and fixes the fan body 101, ensuring that the fan body 101 can maintain the angle and achieve the effect of stably changing the orientation of the fan body 101. The electromagnetic brake and the clamping effect of the electromagnetic brake are both mature technologies in the prior art and are conventional technologies used by those skilled in the art. They are not the content to be protected in this application, so they will not be described in detail here.
[0053] like Figure 5 As shown:
[0054] The mating bracket 401 has multiple mating threaded holes.
[0055] The mounting bracket 401 can be fixed by screwing bolts into multiple mating threaded holes, thereby fixing the entire device.
