The existing quick-freezing air coolers are divided into floor-mounted and ceiling-mounted according to different usage requirements. For quick-freezing products in different locations, the air outlet orientation of the floor-mounted quick-freezing air coolers needs to be customized specifically. Therefore, the same type of air cooler is not convenient to meet the usage requirements of different scenarios; 2. Currently, the most commonly used method for removing frost is electric heating or hot air defrosting. This method requires stopping the quick-freezing air cooler and then heating the copper pipes and fins of the evaporator. Not only is the heating time long, but the temperature is also high. After defrosting is completed, the quick-freezing air cooler is operated. Then, since there is still a lot of heat in the pipes and fins of the evaporator of the quick-freezing air cooler, it greatly affects the rapid cooling effect of the quick-freezing air cooler and the problem of the operating burden of the quick-freezing air cooler.

[0014] A method for using a quick-freezing cold air blower with adjustable air outlet comprises the following steps: S1: When the position of the air outlet of the adjustable exhaust hood needs to be adjusted, the reduction motor is started, and the rotation of the reduction motor is that the worm drives the worm wheel to rotate, and the rotation of the worm wheel drives the steering ball to rotate 90° counterclockwise in the direction shown in the figure through the connecting shaft, and the through hole of the three-way hole originally facing the exhaust fan is turned to the lower exhaust outlet, and the through hole of the three-way hole originally facing the upper part is turned to the exhaust fan, and the through hole of the three-way hole originally facing the side exhaust outlet is turned to the upper part, so that the quick-freezing air cooler is turned from the side exhaust outlet to the lower exhaust outlet; S2: If the air outlet position needs to be changed again, just perform the above operation in reverse. Since the steering ball is in a rotatable state inside the adjustable exhaust hood, the lock tongue of the electric lock is inserted into the slot provided in the rotating disk, thereby completing the locking and fixing of the worm wheel and the worm, that is, the position state of the steering ball is also locked and fixed; S3: When in use, the defrost liquid is filled in the purification box. The defrost liquid can be a saline solution, ethylene glycol antifreeze, white vinegar solution, propylene glycol antifreeze or defrost agent, etc. Different defrost liquids need to be selected according to the use scenario of the quick freezing air cooler, preferably a non-toxic saline solution; S4: Then, the centrifugal pump is started to operate so that the salt water solution in the purification box enters the liquid separation pipe through the connecting pipe, and then enters into the multiple liquid discharge pipes from the liquid separation pipe and is sprayed out from the multiple liquid spray holes opened at the bottom of the liquid discharge pipe to the dynamic fins and the copper pipe. The salt dissolved in the water will lower the freezing point of the water, making the freezing point of the solution lower than the freezing point of pure water. When the salt solution contacts the frost, the melting point of the frost can be lowered, so that the frost can be melted at a lower temperature, thereby accelerating the defrosting speed and completing the defrosting operation. S5: The dripping salt water solution can be collected by the liquid collection tray, and the collected salt water solution is gathered in the purification box, and the dust and lint mixed in the salt water solution are effectively filtered through the filter screen inside the purification box, so as to realize the recovery and reuse of salt water and effectively save resource costs; S6: In order to further accelerate the frost removal efficiency on the dynamic fins and copper tubes, the salt water solution passing through the heating tank can be heated by a heating pipe arranged inside the heating tank, so that the salt water is heated to room temperature water, thereby further improving the melting and removal efficiency of the frost; S7: After long-term use, the cold air generated by the quick freezing air cooler is likely to clog the multiple liquid spray holes opened at the bottom of the drain pipe. Therefore, when the quick freezing air cooler is working normally, the drain pipe is driven by the driving component to rotate 90° so that the multiple liquid spray holes opened in the drain pipe are all located below the arc-shaped cover, and the arc-shaped cover covers the multiple liquid spray holes for protection. When defrosting is required, the drain pipe is driven by the driving component to rotate 90° in the opposite direction so that the liquid spray holes are exposed again, thereby achieving effective protection of the liquid spray holes. S8: In order to further improve the defrosting efficiency, the two rotating shafts are driven to rotate synchronously by the driving component 2, and the rotating shaft rotates to lift the force bars welded at the bottom ends of the fins 1 and 2 through the protrusions. At this time, the waist-round hole grooves 1 and 2 can effectively avoid the copper tube, and under the action of the gravity of the fins 1 and 2, the fins 1 and 2 move back and forth up and down along the direction of the internal notch of the guide frame, thereby accelerating the dripping rate of the defrosting liquid; S9: The contacting sides of fin 1 and fin 2 rub against each other, thereby generating heat, which is transferred to the frost-containing sides of fin 1 and fin 2 through heat transfer, so that the frost also melts at the contacting positions of fin 1 and fin 2, and the shaking off and melting of the frost is further accelerated under the micro-vibration generated by the reciprocating movement of fin 1 and fin 2; S10: When the quick-freezing air cooler is running, frost is easily generated at the positions of the waist-round hole slots 1 and 2 opened on the two fins 1 and 2 of the dynamic fins, thereby affecting the up and down movement of the dynamic fins. Therefore, when the dynamic fins are not defrosted, the waist-round hole slots 1 and 2 are covered by two shielding covers, thereby effectively preventing frost at the positions of the waist-round hole slots 1 and 2 from affecting the normal operation of the dynamic fins.

[0015] Beneficial Effects Compared with the prior art, the present invention provides a quick-freezing cold air blower with adjustable air outlet, which has the following beneficial effects: 1. The quick-freezing cold air fan in the present invention can adjust the air outlet orientation of the adjustable exhaust hood in a targeted manner through the direction adjustment component, so that the quick-freezing cold air fan can meet the use requirements of different scenarios.

[0016] 2. The present invention adopts the liquid spraying mechanism and circulation system of the defrosting system to effectively remove the frost formed on the dynamic fins and the outer surface of the copper tube at room temperature.

[0017] 3. The present invention drives the drain pipe to rotate 90° through a driving component, so that the arc-shaped cover covers and protects multiple spray holes. When defrosting operation is required, the drain pipe is driven by the driving component to rotate 90° in the opposite direction, so that the spray holes are exposed again, thereby realizing effective anti-blockage operation of the spray holes.

[0018] 4. The present invention realizes the vibration of the dynamic fins through the structure of the dynamic fins themselves and the second driving protrusion of the driving component to lift the two fins of the dynamic fins in an offset manner, thereby accelerating the efficiency of the defrosting system in removing the frost formed on the outer surface.

[0019] 5. The contact surfaces of the dynamic fins of the present invention generate heat through vibration friction, and the frost produced on the opposite surfaces of the dynamic fins is accelerated to melt through heat transfer, further improving the frost removal efficiency on the dynamic fins. This process is carried out at room temperature and does not require heating and defrosting by electric heating or hot air, effectively improving the rapid refrigeration effect of the quick-freezing air cooler.

[0020] 6. When the dynamic fins of the present invention are not defrosted, the two shields cover the first and second girdle hole grooves, thereby effectively preventing frost from forming at the first and second girdle hole grooves to affect the normal operation of the dynamic fins.

When in use, since the existing quick-freezing air coolers need to be divided into floor-standing installation and ceiling installation according to different usage requirements, and for quick-freezing products in different positions, the floor-standing quick-freezing air coolers need to customize the direction of the air outlet. Therefore, the quick-freezing air cooler in the present invention can adjust the direction of the air outlet of the adjustable exhaust hood 1 through the direction adjustment component 9, so that the quick-freezing air cooler can meet the usage requirements of different scenarios. After the quick-freezing air cooler is used for a long time, the copper of the evaporator inside it will be Frost is easy to form on the copper pipes and fins, which not only affects the cooling effect of the fins, but also affects the service life of the evaporator. Therefore, the frost on the copper pipes and fins of the internal evaporator needs to be removed. At present, the common method of removing frost is electric heating or hot air defrosting. This method requires stopping the operation of the quick-freezing air cooler, and then heating the copper pipes and fins of the evaporator. Not only is the heating time long, but the temperature is also high. After the defrosting is completed, the quick-freezing air cooler is operated. Then, since there is still a lot of heat in the pipes and fins of the evaporator of the quick-freezing air cooler, it greatly affects the rapid cooling effect of the quick-freezing air cooler, as well as the quick-freezing air cooler.

[0032] A method for using a quick-freezing cold air blower with adjustable air outlet comprises the following steps: S1: When the position of the air outlet of the adjustable exhaust hood 1 needs to be adjusted, the reduction motor 16 is started, and the reduction motor 16 rotates so that the worm 17 drives the worm wheel 21 to rotate, and the worm wheel 21 rotates through the connecting shaft 22 to drive the steering ball 12 to rotate. Figure 4 The direction shown in the figure is rotated counterclockwise by 90°, and the through holes of the three-way hole 11 originally facing the exhaust fan 10 are turned to the lower exhaust port 13, and the through holes of the three-way hole 11 originally facing upward are turned to the exhaust fan 10, and the through holes of the three-way hole 11 originally facing the side exhaust port 14 are turned upward, so that the quick-freezing air cooler is turned from exhausting the side exhaust port 14 to exhausting the lower exhaust port 13; S2: If the air outlet position needs to be changed again, the above operation only needs to be performed in reverse. Since the steering ball 12 is in a rotatable state inside the adjustable exhaust hood 1, the lock tongue of the electric control lock 18 is inserted into the slot 19 provided in the rotating disk 20, thereby completing the locking and fixing of the worm wheel 21 and the worm 17, that is, the position state of the steering ball 12 is also locked and fixed; S3: When in use, the defrosting liquid is filled in the purification box 30. The defrosting liquid can be a saline solution, an ethylene glycol antifreeze, a white vinegar solution, a propylene glycol antifreeze or a defrosting agent, etc. Different defrosting liquids need to be selected according to the use scenario of the quick freezing air cooler, preferably a non-toxic saline solution; S4: Then, the centrifugal pump 29 is started to operate so that the salt solution in the purification box 30 enters the liquid dispensing pipe 27 through the connecting pipe 28, and then enters the plurality of liquid dispensing pipes 26 from the liquid dispensing pipe 27 and is sprayed from the plurality of liquid spraying holes 37 opened at the bottom of the liquid dispensing pipe 26 to the dynamic fins 6 and the copper tube 7. The salt dissolved in the water will lower the freezing point of the water, making the freezing point of the solution lower than the freezing point of pure water. When the salt solution contacts the frost, the melting point of the frost can be lowered, so that the frost can be melted at a lower temperature, thereby accelerating the defrosting speed and completing the defrosting operation. S5: The dripping salt solution can be collected by the liquid collecting tray 24, and the collected salt solution is gathered in the purification box 30, and the dust and lint mixed in the salt solution are effectively filtered by the filter 41 inside the purification box 30, so as to realize the recovery and reuse of salt water and effectively save resource costs; S6: In order to further accelerate the frost removal efficiency on the dynamic fins 6 and the copper tubes 7, the salt water solution passing through the heating tank 40 can be heated by the heating pipe arranged inside the heating tank 40, so that the salt water is heated to normal temperature water, thereby further improving the melting and removal efficiency of the frost; S7: After the quick freezing air cooler is used for a long time, the cold air generated by it is easy to cause blockage to the multiple liquid spray holes 37 opened at the bottom of the drain pipe 26. Therefore, when the quick freezing air cooler is working normally, the drain pipe 26 is driven by the driving component 1 25 to rotate 90 degrees, so that the multiple liquid spray holes 37 opened in the drain pipe 26 are all located below the arc-shaped cover 31, and the arc-shaped cover 31 covers and protects the multiple liquid spray holes 37. When defrosting is required, the drain pipe 26 is driven by the driving component 1 25 to rotate 90 degrees in the opposite direction, so that the liquid spray holes 37 are exposed again, thereby realizing effective protection of the liquid spray holes 37. S8: In order to further improve the defrosting efficiency, the two rotating shafts 42 are driven to rotate synchronously by the driving assembly 2 43. The rotating shaft 42 rotates to lift the force bars 53 welded at the bottom ends of the fins 1 45 and 2 fins 48 through the protrusions 50. At this time, the waist-round hole groove 1 46 and the waist-round hole groove 2 47 can effectively avoid the copper tube 7. Under the action of the gravity of the fins 1 45 and 2 fins 48, the fins 1 45 and 2 fins 48 move back and forth up and down along the inner notch direction of the guide frame 44, thereby accelerating the dripping rate of the defrosting liquid. S9: The contacting sides of the fin 1 45 and the fin 2 48 rub against each other, thereby generating heat, which is transferred to the frost-containing sides of the fin 1 45 and the fin 2 48 through heat transfer, so that the frost also melts at the contacting positions of the fin 1 45 and the fin 2 48, and the shaking off and melting of the frost is further accelerated under the micro-vibration generated by the reciprocating up and down movement of the fin 1 45 and the fin 2 48; S10: When the quick-freezing air cooler is running, frost is easily generated at the positions of the waist-round hole groove 1 46 and the waist-round hole groove 2 47 formed on the two fins 1 45 and the fin 2 48 of the dynamic fin 6, thereby affecting the up and down movement of the dynamic fin 6. Therefore, when the dynamic fin 6 is not defrosted, the waist-round hole groove 1 46 and the waist-round hole groove 2 47 are covered by two shielding covers 49, thereby effectively preventing frost at the positions of the waist-round hole groove 1 46 and the waist-round hole groove 2 47 from affecting the normal operation of the dynamic fin 6.
