[0036] As attached Figure 1-6 As shown, this application provides an air conditioning circulation fan through the following technical solution, including:

[0037] The machine head 1 has a first air duct 11 inside. One end of the first air duct 11 has a first air inlet 111, and the other end of the first air duct 11 has a first air outlet 112. The first air duct 11 also has a first fan 12 inside. Driven by the first fan 12, external air enters the first air duct 11 through the first air inlet 111 and then flows out through the first air outlet 112.

[0038] The machine base 2 has a machine head 1 positioned above it. The machine base 2 includes:

[0039] The refrigeration assembly includes a compressor 201, an evaporator 202, and a condenser 203.

[0040] Water-cooled assembly 21 is arranged around condenser 203;

[0041] The second air duct 22 has a second air inlet 221 at one end and a second air outlet 222 at the other end. The evaporator 202 is located at the second air inlet 221 and the second air outlet 222 is connected to the first air duct 11. The second air duct 22 is also equipped with a second fan 23. Driven by the second fan 23, the outside air enters the second air duct 22 after being cooled into cold air by the evaporator 202 through the second air inlet 221, and then enters the first air duct 11 through the second air outlet 222.

[0042] The third air duct 24 is separated from the second air duct 22. One end of the third air duct 24 is provided with a third air inlet 241, and the other end of the third air duct 24 is provided with a third air outlet 242. The condenser 203 is provided in the third air inlet 242. The third air duct 24 is also provided with a third fan 25. Driven by the third fan 25, the outside air enters the third air duct 24 through the third air inlet 242 and cools the condenser 203 before flowing out through the third air outlet 242.

[0043] The cold air entering the first air duct 11 mixes with the air inside the first air duct 11 to form cold air, which then flows out from the first air outlet 112.

[0044] Compared with the prior art, this application has the following beneficial effects: the external air entering the second air duct is cooled by the refrigeration components installed in the base, and then enters the first air duct and mixes with the air in the first air duct to form cold air that is sent out. Thus, cooling is achieved while the air circulates and convects. The air volume of the cold air can also be adjusted by changing the temperature and proportion of the cold air entering the first air duct, thereby achieving the corresponding adjustment of cooling.

[0045] In the technical solution applied in this embodiment, the first fan 12 inside the first air duct 11 operates, drawing external air into the first air duct 11 through the first air inlet 111 and then out through the first air outlet 112, thereby achieving air circulation within the area where the air conditioning circulation fan is located. To achieve the effect of air circulation, the first fan 12 is generally selected as an axial flow fan, so that the air flows in a straight line within the first air duct 11, reducing airflow resistance.

[0046] Specifically, the base 2 is also equipped with a volute 26, and the second air duct 22 is located inside the volute 26. The volute 26 separates the second air duct 22 from the third air duct 24, so that the second air duct 22 and the third air duct 24 are not connected to each other. The evaporator 202 is located at the inlet of the volute 26. Driven by the second fan 23 in the second air duct 22, the outside air is drawn into the second air duct 22 through the second air inlet 221. When the outside air passes through the second air inlet 221, it exchanges heat with the evaporator 202 and is cooled down, so that the air entering the second air duct 22 is cold air with a temperature lower than the ambient temperature. Since the first air duct 11 is connected to the second air outlet 222 of the second air duct 22, the cold air in the second air duct 22 continues to enter the first air duct 11 and mixes with the existing air in the first air duct 11 to form cold air, which is sent out through the first air outlet 112. Thus, the air circulation is achieved while the cooling effect is also achieved. In addition, by adjusting the second fan 23 or the evaporator 202, the air volume or temperature of the cold air in the second air duct 22 can be changed, thereby changing the air volume and temperature of the cold air formed by mixing the cold air with the existing air in the first air duct 11, and realizing the corresponding adjustment of cooling and temperature reduction.

[0047] In this embodiment, the second fan 23 is a centrifugal fan, which can change the cold air that enters the second air duct 22 in a straight line to be sent into the first air duct 11 in a vertical direction, reducing the area occupied by the second air duct 22 and making it easier to set up the second air duct 22 and the third air duct 28 in the base 2 at the same time. In addition, the cold air that enters the first air duct 11 in a vertical direction is more likely to collide with the air flowing in a straight direction in the first air duct 11, improving the mixing effect and making the temperature of the cold air sent out from the first air outlet 112 uniform, avoiding sudden changes in temperature that affect the performance.

[0048] In the technical solution applied in this embodiment, a wind box 28 is also provided inside the base 2, a third air duct 24 is located inside the wind box 28, a condenser 203 is disposed at the inlet of the wind box 28, and a third fan 25 is disposed at the outlet of the wind box 28. When the refrigeration components are working, the evaporator 202 is used to absorb heat, so its surface temperature is relatively low, while the condenser 203 is used to release heat, so its surface temperature is relatively high. Therefore, driven by the third fan 25, while external air enters the third air duct 28 from the inlet of the wind box 28, the external air cools the condenser 203 at the inlet of the wind box 28. Because the outer wall of the base 2 has a mesh structure, the external air entering the third air duct 28 includes both ambient air entering through the outer wall of the base 2 and air inside the base 2. The ambient air is at room temperature, while the air inside the base 2 is at a higher temperature due to the heat generated by the components inside the base 2. This air cannot effectively cool the condenser 203 and will also become hot air after absorbing heat from the condenser 203. This hot air, after being discharged from the outlet of the air box 28, will damage the cooling effect of the air conditioner's circulating fan and affect the user experience.

[0049] To this end, a water distribution tank 281 is installed inside the air box 28 above the condenser 203. The water distribution tank 281 is equipped with a water supply pipe (not shown in the figure) connected to the first water tank 27. Water from the first water tank 27 enters the water distribution tank 281 through the water supply pipe, and then drips from the water distribution tank 281 onto the condenser 203 to cool it down. In this way, the combined effect of water cooling in the water distribution tank 281 and air cooling from the third fan 25 achieves sufficient cooling of the condenser 203, ensuring the overall operating effect of the refrigeration components. In addition, the air entering the third air duct 28 after passing through the condenser 203 is cooled by the water in the water distribution tank 281, which greatly reduces its temperature rise. Therefore, the air discharged from the outlet of the air box 28 has little impact on the cooling effect of the circulating fan.

[0050] In the technical solution applied in this embodiment, in order to make full use of the cooling water of the condenser 203 and the condensate of the evaporator 202, a water collection system that can be used for circulation within a certain period is formed by the first receiving tank 261 below the evaporator 202, the second receiving tank 282 below the condenser 203, the first water tank 27, and the second water tank 29. Specifically, a first water tank 27 is provided at the bottom of the base 2; a first receiving tank 261 is provided in the volute 26 below the evaporator 202, and a first water outlet 262 is provided in the first receiving tank 261, which is connected to the first water tank 27; a second receiving tank 282 is provided in the air box 28 below the condenser 203, and a second water outlet 283 is provided in the second receiving tank 282, which is connected to the first water tank 27. In this way, the condensate from the evaporator 202 flows into the first water tank 27 through the first outlet 262, and the cooling water from the condenser 203 flows into the second outlet 283, respectively, achieving collection and recycling. Because the condensate from the evaporator 202 is at a lower temperature, it can also appropriately neutralize the high temperature of the cooling water from the condenser 203, ensuring that the temperature of the cooling water re-entering the water distribution tank 281 is not too high and thus does not affect the cooling effect. The base 2 also has a removable second water tank 29, which is connected to the first water tank 27. By adding water to the removed second water tank 29, water loss due to evaporation and other factors can be replenished, ensuring that the entire water collection system maintains the necessary water volume.

[0051] In addition, a neck 3 is provided between the base 2 and the head 1. The neck 3 has a hollow pipe 31. One end of the hollow pipe 31 is connected to the second air outlet 222, and the other end of the hollow pipe 31 is connected to the first air duct 11. While the neck 3 fixes the head 1 to the base 2, it also realizes the connection between the first air duct 11 and the second air duct 22 through the hollow pipe 31.

[0052] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
