[0002] When an air conditioner is operating, condensed water often forms on the heat exchanger. A small amount of condensed water can improve the heat exchange effect. However, if the condensed water adheres to the fin surface for a long time and cannot be discharged in time, it will affect the heat exchange efficiency. Especially in winter, it will also cause frosting on the heat exchanger surface, greatly reducing the working efficiency of the air conditioner. In addition, if the condensed water cannot be discharged for a long time, it will also cause the fin surface to rust and corrode, affecting the heat exchange efficiency and reducing the service life of the fins.

Detailed Embodiments

[0020] The following further describes the present invention in conjunction with embodiments, but is not limited to the content in the specification.

[0021] As Figure 1 and Figure 2 shown, the present invention discloses an outdoor unit of an air conditioner, including a heat exchanger 10, a fan 20 and a wind guiding structure 30. The heat exchanger 10 has a diversion surface for guiding the condensed water to be discharged in a predetermined flowing direction; the fan 20 is arranged corresponding to the heat exchanger 10, and the fan can rotate forward and backward. That is to say, the fan 20 can blow air towards the heat exchanger 10 or blow air in the direction away from the heat exchanger; the wind guiding structure 30 is arranged between the heat exchanger 10 and the fan 20, and the wind guiding structure 30 is used to guide the fan 20 to blow air towards the flowing direction of the condensed water on the heat exchanger 10.

[0022] Specifically, when the air conditioner is in cooling mode in summer, the fan of the outdoor unit can rotate forward, and at this time, the blowing direction of the fan is away from the heat exchanger. When in heating mode in winter, the fan of the outdoor unit rotates in reverse. At this time, the blowing direction of the fan is towards the heat exchanger. The air flow blown by the fan first passes through the air guiding structure. Under the guidance of the air guiding structure, the air blown by the fan blows towards the flowing direction of the condensate water on the heat exchanger (usually towards the direction of gravity), thereby accelerating the flow of the condensate water.

[0023] By arranging an air guiding structure between the heat exchanger and the fan in the outdoor unit of the air conditioner of the present invention, when the fan blows air towards the heat exchanger, the air flow first passes through the air guiding structure. Under the guidance of the air guiding structure, the air blown by the fan blows towards the flowing direction of the condensate water on the heat exchanger, thereby accelerating the flow of the condensate water, enabling the condensate water to be quickly discharged, preventing the condensate water from condensing into frost on the surface of the heat exchanger, and greatly improving the heat exchange efficiency.

[0024] The air guiding structure 30 includes a plurality of air guiding plates 31. An air guiding channel 32 is formed between adjacent air guiding plates 31, and the air outlet direction of the air guiding channel 32 faces the flowing direction of the condensate water. By arranging a plurality of air guiding plates 31 in the outdoor unit of the air conditioner of the present invention, an air guiding channel 32 is formed between adjacent air guiding plates 31, thereby guiding the air flow to blow towards the moving direction of the condensate water and accelerating the flow of the condensate water.

[0025] Furthermore, the air outlet direction of the air guiding channel 32 faces the ground direction. By guiding the air outlet direction of the air guiding channel towards the ground direction in the outdoor unit of the air conditioner of the present invention, it can cooperate with gravity to accelerate the flow of the condensate water, enable the condensate water to be quickly discharged, prevent the condensate water from condensing into frost on the surface of the heat exchanger, and greatly improve the heat exchange efficiency.

[0026] Furthermore, the air guiding plate 31 is of an arc-shaped plate structure, and the air guiding channel 32 is a streamlined air duct. By adopting an arc-shaped plate structure for the air guiding plate 31 in the outdoor unit of the air conditioner of the present invention, the air guiding channel 32 becomes a streamlined air duct. The streamlined air duct can reduce the turbulent flow, resulting in less energy loss during the process of the air flow changing direction and avoiding the loss of air volume.

[0027] The fan of the outdoor unit is an axial flow fan. During the rotation of the axial flow fan, the blown air flow advances in a spiral shape. When side air intake is adopted, the orientations of the arc-shaped plates are the same, so turbulent flow will occur when the air flow enters some of the air guiding channels, thereby causing air volume loss.

[0028] To solve this problem, in this embodiment, the air deflector 31 includes a first air deflector 31a and a second air deflector 31b. Both the first air deflector 31a and the second air deflector 31b are arc-shaped plates. The convex arc surface of the first air deflector 31a faces away from the ground, and the convex arc surface of the second air deflector 31b faces the ground. By setting both the first air deflector 31a and the second air deflector 31b as arc-shaped plates, with the convex arc surface of the first air deflector 31a facing away from the ground and the convex arc surface of the second air deflector 31b facing the ground, the air conditioner outdoor unit of the present invention can avoid flow interference and greatly reduce the loss of air volume.

[0029] Specifically, the air guiding structure 30 in Figure 1 is divided into a first region 30a, a second region 30b, and a third region 30c. Both the first region 30a and the second region 30b are Figure 1 regions corresponding to the fan in Figure 1 Among them, the first region 30a is the Figure 1 region on the left side of the fan shaft, and the second region 30b is the Figure 1 region on the right side of the fan shaft in

[0030] The third region 30c is the region surrounding the circumferences of the first region 30a and the second region 30b.

[0030] The first air deflector 31a is located within the first region 30a, and the second air deflector 31b is located within the second region 30b. Both the first air deflector 31a and the second air deflector 31b are arc-shaped plates. The convex arc surface of the first air deflector 31a faces away from the ground, and the convex arc surface of the second air deflector 31b faces the ground.

[0031] When the fan blades 21 of the blower 20 rotate to the first region 30a, the fan blades 21 rotate from top to bottom. Since the convex arc surface of the first air deflector 31a faces away from the ground, at this time, the convex arc surface of the first air deflector 31a becomes the windward surface, thus enabling the air flow to be guided more smoothly. The effect data is as Figure 3 shown; Similarly, when the fan blades 21 of the blower 20 rotate to the second region 30b, the fan blades 21 rotate from bottom to top. The convex arc surface of the second air deflector 31b faces the ground. At this time, the convex arc surface of the second air deflector 31b becomes the windward surface, thus enabling the air flow to be guided more smoothly. The effect data is as Figure 4 shown.

[0032] Furthermore, the air deflector 31 further includes a third air deflector 31c. The third air deflector 31c is disposed within the third region 30c. The shape of the third air deflector 31c is the same as that of the first air deflector 31a, which can be used to evenly guide the air flow towards the direction of the heat exchanger, making the air volume distribution on the surface of the heat exchanger more uniform, so as to improve the heat exchange efficiency of the heat exchanger.

[0033] In the above embodiment, the air guiding structure 30 is an air guiding grille. The shape of the air guiding grille matches the shape of the heat exchanger 10, and the air guiding grille is U-shaped and surrounds the outer periphery of the fan. By setting the shape of the air guiding grille to match the shape of the heat exchanger 10, the air volume distribution on the surface of the overall heat exchanger can be relatively uniform, thereby improving the heat exchange effect of the heat exchanger.

[0034] In the above embodiment, the air guiding grille is attached to the heat exchanger 10, which can improve the air guiding effect.

[0035] In the above embodiment, fins for heat exchange are provided on the heat exchanger 10. The fins are arranged vertically, and the surface of the fins is an air guiding surface. By providing vertically arranged fins, the air conditioner outdoor unit of the present invention can, while exchanging heat, allow condensed water to drain under the action of gravity. In cooperation with the air guiding structure, the blowing of the fan can blow downward towards the condensed water, and the condensed water can quickly drain away under the action of gravity and wind force, thereby preventing the condensed water from condensing into frost on the surface of the heat exchanger and greatly improving the heat exchange efficiency.

[0036] According to the second embodiment of the present invention, an air conditioner is further disclosed, including the above-mentioned air conditioner outdoor unit.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
