[0041] See also Figure 1 As shown, an embodiment of the present application provides a guide member 50, which is installed at the air outlet of the fan 30 and is used to adjust the wind direction and wind speed of the cold air output by the fan 30. The guide member 50 includes a connecting portion and a guide portion.

[0042] In some embodiments, the connecting portion is installed at the air outlet of the fan 30; the air guide portion is installed at the end of the connecting portion away from the fan 30, and the air guide portion includes a wind shield 2 and a wind guide 3, and the wind shield 2 is connected between the connecting portion and the wind guide 3;

[0043] In this embodiment, the connecting part includes a connecting member 1 and a fixing member, wherein the connecting member 1, the wind shield plate 2 and the wind guide plate 3 are integrally formed; a fixing hole 11 is provided on the connecting member 1, and the connecting member 1 is installed at the air outlet of the fan 30 through the cooperation between the fixing member and the fixing hole 11.

[0044] At least two ventilation holes 21 are disposed on the wind shield 2 . A plurality of the ventilation holes 21 are disposed on the wind shield 2 , and a wind shield 22 is formed between two adjacent ventilation holes 21 .

[0045] The guide member 50 provided in the embodiment of the present application blocks the flow of cold air through the setting of the wind shield 2, thereby changing the flow direction and the air outlet speed of the cold air, thereby reducing the abnormal noise generated by blowing the fins; at the same time, ventilation holes 21 are set on the wind shield 2, and a wind shield 22 is formed between the two ventilation holes 21. The wind shield 22 plays a role in breaking up the high-speed wind field, thereby improving the wind field distribution and the abnormal noise generated by blowing the fins; in addition, through the setting of the wind guide plate 3, the flow direction of the cold air is further changed, so that the cold air will not blow directly to the water receiving tray, thereby solving the problem of blowing water and further improving the abnormal noise generated by blowing the fins.

[0046] See also Figure 3 As shown, in some embodiments, two ventilation holes 21 are provided on the wind shield 2, and the two ventilation holes 21 are arranged side by side on the wind shield 2, and a wind shield 22 is formed between the two ventilation holes 21, and the wind shield 22 is located on the central axis of the wind shield 2.

[0047] During the operation of the air conditioner, the closer the air outlet of the fan 30 is to the center, the greater the increase in wind speed. The wind speed in the central area of ​​the air outlet is the highest, so when the high-speed wind in the middle blows the fins, obvious abnormal noise will be generated.

[0048] In some embodiments, the width of the wind shield 22 is 5 mm to 15 mm. Specifically, the width of the wind shield 22 can be set to one of 5 mm, 10 mm, and 15 mm or a range formed between any two values.

[0049] The embodiment of the present application forms a wind shield 22 on the central axis of the wind shield 2, and uses the wind shield 22 to block the cold wind in the middle, thereby breaking up the high-speed wind field in the middle and causing it to flow to the ventilation holes 21 on both sides, thereby reducing the wind speed and forming a uniform wind field distribution, thereby improving the problem of excessive wind speed and further improving the abnormal sound problem.

[0050] See also Figure 4 As shown, in other embodiments, the wind shield plate 2 may further be provided with four ventilation holes 21 , and the wind shield member 22 includes a central wind shield member 221 and a side wind shield member 222 .

[0051] The central wind shield 221 is located on the central axis of the wind shield plate 2 , and the plurality of ventilation holes 21 are symmetrically arranged on both sides of the central wind shield 221 ; the side wind shield 222 is located between two adjacent ventilation holes 21 .

[0052] In some embodiments, the width of the central wind shield 221 is 5 mm to 15 mm. Specifically, the width of the central wind shield 221 can be set to one of 5 mm, 10 mm, and 15 mm or a range formed between any two values.

[0054] In some embodiments, the shape of the ventilation hole 21 is selected from at least one of a circle, an ellipse, an oblong, a rectangle, a polygon, an irregular polygon, and a star.

[0055] In some embodiments, the porosity of the wind shield 2 is R=S / Q, wherein 70%≤R≤80%, S is the total area of ​​the plurality of ventilation holes 21 , and Q is the total area of ​​the wind shield 2 .

[0056] In this embodiment, the through-hole ratio of the wind shield plate 2 is 78%.

[0057] See also Figure 2 As shown, in some embodiments, a first set angle θ1 is formed between the wind shield 2 and the air outlet direction of the fan, wherein the first set angle θ1 is 0° to 90°. Specifically, the first set angle θ1 can be set to any one of 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90° or a range formed between any two values.

[0058] In some embodiments, a second set angle θ2 is formed between the wind shield 2 and the wind guide plate 3, wherein the second set angle θ2 is 0° to 90°.

[0059] In some embodiments, a third set angle θ3 is formed between the air guide plate 3 and the horizontal plane, wherein the third set angle θ3 is 0° to 10°. Specifically, the third set angle θ3 can be set to any value of 5°, 10° or a range formed between any two values.

[0060] In this embodiment, the first set angle θ1 is 80°, the second set angle θ2 is 90°, and the third set angle θ3 is 10°. The embodiment of the present application limits the first set angle to ensure that the wind shield plate 2 can provide a suitable wind shielding effect, and facilitates CNC processing of the air guide plate 3; at the same time, the third set angle is limited to ensure that the air guide plate 3 can change the angle at which the cold air blows to the evaporator fins.

[0061] The embodiment of the present application solves the problem of the fan blowing water by setting a suitable angle of the air guide plate 3 to avoid the cold air outlet direction directly toward the water receiving tray. In addition, since the air guide plate 3 guides the cold air and changes the cold air outlet direction, the abnormal noise problem caused by the cold air blowing toward the evaporator fins is solved.

[0063] The embodiment of the present application sets a reasonable length of the wind guide plate 3 so that the orthographic projection of the wind shield plate 2 falls on the wind guide plate 3, so that the wind shield plate 2 can guide the cold air in the direction of the wind guide plate 3, and further guide it through the wind guide plate 3, avoiding the cold air from being blown directly toward the water receiving tray, thereby solving the problem of water blowing by the fan.

[0064] See also Figure 1 to Figure 3 As shown, in some embodiments, the guide portion also includes a bending plate 4, and the bending plate 4 is connected between the connecting portion and the wind shield 2. In this embodiment, the bending plate 4 is formed by bending inward on both sides of the wind shield 2, and the top of the bending plate 4 is connected to the connecting member 1.

[0065] In the embodiment of the present application, a bending plate 4 is provided to increase the structural strength of the wind shield 2. Since the bending plates 4 are located on both sides of the wind shield 2, they correct the outlet direction of the cold air, thereby making the wind field evenly distributed.
