Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this embodiment, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0035] Figures 1 to 8 The outdoor unit and air conditioner provided by the present invention are shown. As can be seen from the figure, the outdoor unit of the present invention includes an outdoor unit housing 100, an outdoor fan 200, and a shielding device 300. The outdoor unit housing 100 has an air outlet 110. The outdoor fan 200 is located inside the outdoor unit housing 100 and connected to the outdoor unit housing 100. The shielding device 300 is connected to the outdoor unit housing 100 and is used to expose the air outlet 110 when the rotation speed of the outdoor fan 200 is higher than a preset value, or to block the air outlet 110 when the rotation speed of the outdoor fan 200 is lower than a preset value.

[0036] In practical implementation, when the speed of the outdoor fan 200 is lower than the preset value, the shielding device 300 can cover the air outlet 110. Therefore, in rainy weather, rainwater is less likely to enter the outdoor unit casing 100 through the air outlet 110, preventing water ingress into the outdoor unit and improving the user experience. This solves the technical problem of water ingress into outdoor units in existing technologies. Furthermore, when the outdoor fan 200 is running, the air outlet 110 is exposed, ensuring normal heat exchange between the outdoor unit and the outside air, thus enabling the outdoor unit to operate normally.

[0037] like Figure 1 As shown, in this embodiment, the air outlet 110 can be located at the upper end of the outdoor unit housing 100, the air outlet 110 can be circular, and the shielding device 300 and the outdoor fan 200 can be arranged sequentially from top to bottom; the outdoor fan 200 can be an axial flow fan or a centrifugal fan, etc.

[0038] like Figure 1As shown, according to one embodiment of the present invention, the shielding device 300 may include a support unit 310 and at least one shielding unit 320. The support unit 310 is located inside the outdoor unit housing 100 and connected to the outdoor unit housing 100. At least one shielding unit 320 is located at the air outlet 110 and is rotatably connected to the support unit 310. The shielding unit 320 is used to rotate by the wind force of the outdoor fan 200 when the rotation speed of the outdoor fan 200 is higher than a preset value, so as to expose the air outlet 110, or to be reset by its own gravity when the rotation speed of the outdoor fan 200 is lower than the preset value, so as to shield the air outlet 110.

[0039] In practice, the support unit 310 supports the shielding unit 320. When the outdoor fan 200 starts, the outdoor fan 200 (fan blades) rotates, expelling air through the air outlet 110 to the outside of the outdoor unit casing 100. Since the shielding unit 320 is located at the air outlet 110, the outdoor fan 200 provides a wind force to the shielding unit 320. Under the action of the wind force, the shielding unit 320 rotates, exposing the air outlet 110. This exposure ensures that the outdoor unit can exchange heat normally with the outside air, thus enabling the outdoor unit to function normally. When the speed of the outdoor fan 200 is lower than the preset value, for example, when the outdoor fan 200 is turned off, the outdoor fan 200 will stop rotating. When the outdoor fan 200 stops rotating, the shielding unit 320 will rotate in the opposite direction under its own gravity. The shielding unit 320 can block the air outlet 110 when it rains. Therefore, when encountering rainy weather, rainwater is not easy to enter the outdoor unit housing 100 through the air outlet 110, which will not easily cause water to enter the outdoor unit and improve the user experience. This invention uses the wind power of the outdoor fan 200 to drive the shielding unit 320 without the need for other drive structures. Therefore, the outdoor unit has a simple structure and low cost.

[0040] like Figure 4 As shown, according to one embodiment of the present invention, the support unit 310 includes a support component 311 and at least one partition component 312; the support component 311 includes a flange 3110 and a support ring 3120; the flange 3110 is sleeved on the end of the support ring 3120 and can abut against the edge of the air outlet 110; the support ring 3120 is arranged vertically and passes through the outer casing 100 through the flange 3110, and its outer peripheral wall is sealed to the edge of the air outlet 110; the partition component 312 is connected to the inner peripheral wall of the support ring 3120 and is used to divide the air outlet 110 into a plurality of setting areas 111 in which shielding units 320 can be set; the shielding unit 320 is located in the setting area 111 and is rotatably connected to the partition component 312, and the rotation axis of the shielding unit 320 is arranged in the horizontal direction.

[0041] In practice, the support ring 3120 is installed inside the outdoor unit housing 100 through the flange 3110, and the flange 3110 abuts against the edge of the air outlet 110, which can improve the stability of the support ring 3120 inside the outdoor unit housing 100; the outer peripheral wall of the support ring 3120 is sealed to the edge of the air outlet 110, which can prevent rainwater and other liquids from entering the outdoor unit housing 100 from the connection between the outer peripheral wall of the support ring 3120 and the edge of the air outlet 110.

[0042] like Figure 4 As shown, according to one embodiment of the present invention, the dividing component 312 is located inside the support ring 3120 and is used to divide the air outlet 110 into a plurality of setting areas 111 arranged sequentially adjacent to each other along the circumference of the support ring 3120; there are a plurality of shielding units 320, and each setting area 111 is provided with a shielding unit 320.

[0043] In practice, if only one shielding unit 320 is set, the weight of the shielding unit 320 will be relatively heavy, and the outdoor fan 200 will not be able to drive the shielding unit 320 to rotate. By setting multiple shielding units 320, their weight can be reduced, and the outdoor fan 200 can quickly drive each shielding unit 320 through wind power to rotate the shielding unit 320 so as to expose the air outlet 110.

[0044] like Figure 4 As shown, in this embodiment, the number of setting areas 111 can be four, and the number of blocking units 320 can also be four, and the area of ​​each setting area 111 can be equal.

[0045] In practice, the above-mentioned structural design ensures that each shielding unit 320 can be opened simultaneously, the air outlet 110 emits air evenly, and the heat exchange performance of the outdoor unit will not be affected by the shielding unit 320, thus ensuring that the outdoor unit can exchange heat with the outside air normally.

[0046] like Figure 4 As shown, according to one embodiment of the present invention, the partition assembly 312 may include a support column 3121 and a plurality of partition components 3122; the support column 3121 is arranged vertically and located at the middle position of the support ring 3120; the plurality of partition components 3122 extend radially along the support ring 3120 and are evenly distributed along the circumference of the support ring 3120, and are connected between the inner peripheral wall of the support ring 3120 and the outer peripheral wall of the support column 3121, so as to divide the air outlet 110 into a plurality of equally sized installation areas 111; a plurality of shielding units 320 correspond one-to-one with the plurality of partition components 3122 and are rotatably connected.

[0047] In practice, the partition component 3122 is connected between the inner peripheral wall of the support ring 3120 and the outer peripheral wall of the support column 3121, so that the partition component 3122 has two connection points, thereby making the connection strength of the partition component 3122 greater.

[0048] like Figure 1 As shown, according to one embodiment of the present invention, the air outlet 110 may be circular, and the air outlet 110, the support column 3121, the support ring 3120 and the outdoor fan 200 are arranged coaxially, and the area of ​​the air outlet 110 is equivalent to the cross-sectional area of ​​the outdoor fan 200 (fan).

[0049] In practice, the above-mentioned structural design can concentrate the wind power of the outdoor fan 200, which makes it easy for the outdoor fan 200 to quickly drive each shielding unit 320 through the wind power, so that the shielding unit 320 rotates and the air outlet 110 is quickly exposed.

[0050] like Figure 1 As shown, according to one embodiment of the present invention, a plurality of shielding units 320 are arranged to form a cone-shaped space when the rotational speed of the outdoor fan 200 is lower than a preset value. The cone-shaped space has a large-diameter end and a small-diameter end, which are arranged vertically at intervals.

[0051] In practice, the above-mentioned structural design allows rainwater and other liquids to concentrate in the middle of the cone-shaped space.

[0052] like Figure 5 and Figure 6 As shown, in this embodiment, the shielding unit 320 may include a plurality of water-blocking fan rings 321; the plurality of water-blocking fan rings 321 are rotatably connected between two adjacent separating components 3122, and the plurality of water-blocking fan rings 321 are arranged sequentially along the radial inward direction of the support ring 3120, the size of the plurality of water-blocking fan rings 321 decreases sequentially, and they overlap sequentially when the speed of the outdoor fan 200 is lower than a preset value.

[0053] In practice, since there is a certain slope in the radial direction of the support ring 3120, it can prevent rainwater and other liquids from seeping into the interior of the outdoor unit housing 100 from the connection of the two adjacent water baffle rings 321 in the radial direction of the support ring 3120. Thus, when the speed of the outdoor fan 200 is lower than the preset value, the rainwater can be concentrated in the middle of the conical space.

[0054] like Figure 6As shown, in this embodiment, the water-blocking fan ring 321 has a first end and a second end; the first end is provided with a first rotating shaft 3211, and the second end is provided with a first rotating shaft 3212. The extension lines of the first rotating shaft 3211 and the second rotating shaft 3212 are collinear; in two adjacent partition members 3122, the partition member 3122 corresponding to the first end has a blind hole, and the partition member 3122 corresponding to the second end also has a blind hole; the first rotating shaft 3211 and the second rotating shaft 3212 are located in the corresponding blind holes and are rotatably connected to the hole wall of the blind hole.

[0055] like Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, a first region R1 is provided below the connection between the shielding unit 320 and the partition member 3122; a second region R2 is provided below the connection between the shielding unit 320 and the support column 3121; the outdoor unit also includes a water receiving unit 400; the water receiving unit 400 is disposed inside the outdoor unit housing 100 and has a water receiving trough 410, which is located in the first region R1 and the second region R2.

[0056] In practice, while ensuring that rainwater and other liquids can be collected by the water collection tank 410, the volume of the water collection unit 400 should be minimized to reduce the wind power loss of the outdoor fan 200 and ensure that the outdoor unit can exchange heat normally with the outside air.

[0057] like Figure 7 As shown, in this embodiment, the water receiving tank 410 can be in the shape of a cross, the water receiving unit 400 can be connected to the support unit 310, the water receiving unit 400 has a water outlet 420, the water outlet 420 is connected to the water receiving tank 410, and is used to discharge water in the water receiving tank 410 to the outside of the outdoor unit housing 100.

[0058] According to one embodiment of the present invention, the outdoor unit of the present invention may further include a condensate drain pipe, one end of which is connected to the water outlet 420, and the other end of which extends to the outside of the outdoor unit housing 100. The condensate drain pipe is used to discharge water in the water receiving tank 410 to the outside of the outdoor unit housing 100.

[0059] The present invention also provides an air conditioner, including an outdoor unit and an indoor unit as described in the above embodiments, wherein the indoor unit is connected to the outdoor unit.

[0060] In practical implementation, when the speed of the outdoor fan 200 is lower than the preset value, the shielding device 300 can cover the air outlet 110. Therefore, in rainy weather, rainwater is less likely to enter the outdoor unit casing 100 through the air outlet 110, preventing water ingress into the outdoor unit and improving the user experience. This solves the technical problem of water ingress into outdoor units in existing technologies. Furthermore, when the outdoor fan 200 is running, the air outlet 110 is exposed, ensuring normal heat exchange between the outdoor unit and the outside air, thus enabling the outdoor unit to operate normally.
