[0037] The embodiment of the first aspect of the present invention provides an air outlet assembly for an air conditioner outdoor unit, such as Figures 1 to 4 As shown, the air outlet assembly for the air conditioner outdoor unit includes:

[0038] Fixed grille 100, with a first-level windshield device 110 provided on the fixed grille 100

[0039] A rotating grille 200 is provided with a secondary windshield 210. The rotating grille 200 is rotatably connected to the fixed grille 100. The rotating grille 200 has a first state and a second state. In the first state, the projection of the secondary windshield 210 on the plane where the fixed grille 100 is located at least partially covers the windshield projection of the primary windshield 110 on the plane where the fixed grille 100 is located. In the second state, the projection of the secondary windshield 210 on the plane where the fixed grille 100 is located is staggered with the windshield projection of the primary windshield 110 on the plane where the fixed grille 100 is located.

[0040] The grille rotation driving device 300 is connected to the rotating grille (200) and is used to drive the rotating grille 200 to switch between a first state and a second state.

[0041] In the air outlet component for an outdoor air conditioner provided by the present invention, it includes a fixed grille 100, a rotating grille 200, and a grille rotation driving device 300. A primary wind blocking device 110 is provided on the fixed grille 100. A secondary wind blocking device 210 is provided on the rotating grille 200. The fixed grille 100 and the rotating grille 200 are rotatably connected. The grille rotation driving device 300 is connected to the rotating grille 200 to drive the rotating grille 200 to switch between a first state and a second state. In the first state, the projection of the secondary wind blocking device 210 on the plane where the fixed grille 100 is located at least partially covers the wind blocking surface projection of the primary wind blocking device 110 on the plane where the fixed grille 100 is located, so as to increase the air guiding area of the air outlet component for the outdoor air conditioner. In the second state, the projection of the secondary wind blocking device 210 on the plane where the fixed grille 100 is located is staggered from the wind blocking surface projection of the primary wind blocking device 110 on the plane where the fixed grille 100 is located, so as to reduce the air guiding area of the air outlet component for the outdoor air conditioner, and further reduce the possibility of foreign objects entering the outdoor air conditioner.

[0042] For example, in an embodiment of the present invention, the primary wind blocking device 110 includes a plurality of primary spokes, and the secondary wind blocking device 210 includes a plurality of secondary spokes. The number of the primary wind blocking device 110 and the secondary wind blocking device 210 is equal. For example, the fixed grille 100 and the rotating grille 200 are coaxially arranged. The plurality of primary spokes are annularly arrayed on the fixed grille 100 with the center of the fixed grille 100 as the array center. Similarly, the plurality of secondary spokes are annularly arrayed on the rotating grille 200 with the center of the rotating grille 200 as the array center. The fixed grille 100 and the rotating grille 200 are rotatably connected. The grille rotation driving device 300 is connected to the rotating grille 200 to drive the rotating grille 200 to switch between a first state and a second state. In an embodiment of the present invention, when the secondary spokes on the rotating grille 200 completely coincide with the primary spokes on the fixed grille 100, the rotating grille 200 is in the first state, and at this time, the air guiding area of the air outlet component for the air conditioner is the largest; when the secondary spokes on the rotating grille 200 are completely staggered from the primary spokes on the fixed grille 100, the rotating grille 200 is in the second state, and at this time, the air guiding area of the air outlet component for the air conditioner is the smallest, and at this time, the overall spacing of the grille is encrypted, and it can also play a protective role. When the secondary spokes on the rotating grille 200 partially coincide with the primary spokes on the fixed grille 100, the rotating grille 200 is in the first state, and at this time, the air guiding area of the air outlet component for the air conditioner is between the maximum air guiding area and the minimum air guiding area. By adjusting the coincidence ratio between the secondary spokes on the rotating grille 200 and the primary spokes on the fixed grille 100, the air volume can be adjusted, and the protective effect can also be achieved.

[0043] In addition, in another embodiment of the present invention, as Figure 3 and Figure 4As shown, the secondary windshield device 210 further includes a plurality of annular rib plates 220. Each annular rib plate 220 is coaxially and spaced between each secondary spoke. Thus, not only can the strength of the rotary grille 200 be improved, but also the air guiding area in the second state can be further reduced.

[0044] With this structural arrangement, the grille rotation driving device 300 is connected to the rotary grille 200 to drive the rotary grille 200 to switch between the first state and the second state. When the possibility of foreign objects appearing in the current working environment is relatively high, the rotary grille 200 can be switched to the second state to reduce the air guiding area and prevent foreign objects from entering the air conditioner outdoor unit. When the possibility of foreign objects appearing in the current working environment is relatively low, the rotary grille 200 can be switched to the first state to increase the air guiding area. Thus, the working safety of the air conditioner outdoor unit can be improved and the possibility of dangerous accidents can be reduced.

[0045] In an embodiment of the present invention, the fixed grille 100 is used for fixedly connecting to the housing 400 of the air conditioner outdoor unit. The rotary grille 200 is rotatably connected to the outside of the fixed grille 100.

[0046] In an embodiment of the present invention, an arc-shaped chute 120 is provided on one side of the fixed grille 100 close to the rotary grille 200. A pulley is provided on one side of the rotary grille 200 close to the fixed grille 100. The pulley is connected into the arc-shaped chute 120. The pulley can slide in the arc-shaped chute 120 to enable the rotary grille 200 to switch between the first state and the second state.

[0047] In an embodiment of the present invention, a dust-proof baffle 230 is provided at the edge of the rotary grille 200. The dust-proof baffle 230 extends to the outside of the edge of the fixed grille 100 to block the gap between the fixed grille 100 and the rotary grille 200.

[0048] Furthermore, in an embodiment of the present invention, the grille rotation driving device 300 includes a grille motor. The housing of the grille motor is fixedly connected to the rotary grille 200. The output shaft of the grille motor is fixedly connected to the fixed grille 100.

[0049] Specifically, as Figures 1 to 4As shown, both the rotating grille 200 and the fixed grille 100 are circular structures. A circular mounting hole is provided on the housing 400 of the outdoor unit of the air conditioner, and the fixed grille 100 is fixedly connected into the circular mounting hole. The rotating grille 200 and the fixed grille 100 are coaxially arranged, and the rotating grille 200 is rotatably connected to the outside of the fixed grille 100, that is, the rotating grille 200 is located on the side of the fixed grille 100 away from the inside of the outdoor unit of the air conditioner. An arc-shaped chute 120 is provided at a position near the edge on the outer side surface of the fixed grille 100. A pulley is provided on the inner side surface of the rotating grille 200, and the pulley is adapted to the arc-shaped chute 120, and the pulley is slidably mounted into the arc-shaped chute 120. For example, the grille rotation drive device 300 is a grille motor. The housing of the grille motor is fixedly connected to the rotating grille 200, and the housing of the grille motor is coaxially arranged with the rotating grille 200. The output shaft of the grille motor is coaxially and fixedly connected to the fixed grille 100. The grille motor is used to drive the rotating grille 200 to rotate so that the rotating grille 200 is switched between a first state and a second state. An annular dust-proof baffle 230 is provided at the edge of the rotating grille. The end of the annular dust-proof baffle 230 extends to the outside of the edge of the fixed grille 100. Thus, it is possible to prevent external dust from entering the gap between the rotating grille 200 and the fixed grille 100.

[0050] In an embodiment of the present invention, the air outlet assembly for the outdoor unit of the air conditioner further includes a connecting shaft 510, a fan 520 and a fan motor 530.

[0051] Among them, the housing of the fan motor 530 is used to be fixedly connected to the housing 400 of the outdoor unit of the air conditioner. One end of the connecting shaft 510 is connected to the output shaft of the fan motor 530, and the other end of the connecting shaft 510 is rotatably connected to the fixed grille 100. The fan 520 is sleeved and fixed to the connecting shaft 510.

[0052] Furthermore, in an embodiment of the present invention, a fixed shaft 130 is provided on the side of the fixed grille 100 close to the fan 520. A connecting hole is provided on the fixed shaft 130. The end of the connecting shaft 510 passes through the connecting hole, and a bearing is provided between the end of the connecting shaft 510 and the connecting hole.

[0053] Such as Figure 1 and Figure 2As shown in the figure, a connecting shaft 510, a fan 520 and a fan motor 530 are further installed inside the housing 400 of the outdoor unit of the air conditioner. The housing of the fan motor 530 is connected to the inner side wall of the housing 400 of the outdoor unit of the air conditioner through fasteners and a mounting seat. The output shaft of the fan motor 530 is connected to one end of the connecting shaft 510. The other end of the connecting shaft 510 passes through the central connecting shaft 510 of the fan 520 and is connected to the fixed grille 100. Specifically, a fixed shaft 130 is provided at the central axis position of the fixed grille 100, and a connecting hole is provided on the fixed shaft 130. The other end of the connecting shaft 510 passes through the central connecting shaft 510 of the fan 520 and is rotatably connected to the connecting hole. In addition, a bearing is provided between the connecting shaft 510 and the connecting hole.

[0054] Compared with the structure in the prior art where one end of the connecting shaft 510 is fixedly installed, in the present invention, one end of the connecting shaft 510 is connected to the output shaft of the fan motor 530, and the other end of the connecting shaft 510 is rotatably connected to the fixed grille 100. Thus, the connection stability of the fan 520 can be greatly improved, and problems such as the shaking of the outdoor unit of the air conditioner caused by poor connection stability of the fan 520 can be avoided; at the same time, the maximum rotation speed of the fan 520 can also be increased, the air volume can be increased, and thus the heat exchange efficiency can be improved.

[0055] In an embodiment of the present invention, the air outlet assembly for the outdoor unit of the air conditioner further includes a control device and a motor operating state detection device. The motor operating state detection device is used to detect the operating state of the fan motor 530. The control device is connected to the motor operating state detection device and the grille rotation driving device 300. The control device is used to control the operating state of the grille rotation driving device 300 based on the detection result of the motor operating state detection device.

[0056] For example, in the case where the fan motor 530 stops operating, the control device controls the grille rotation driving device 300 to cause the rotating grille 200 to switch to the second state.

[0057] In an embodiment of the present invention, the air outlet assembly of the outdoor unit of the air conditioner further includes an infrared detection device and a control device.

[0058] The infrared detection device is connected to the housing 400 of the outdoor unit of the air conditioner and is used to detect whether there is a foreign object approaching the fixed grille 100 or the rotating grille 200. The control device is connected to the infrared detection device and the grille rotation driving device 300 and is used to control the operating state of the grille rotation driving device 300 based on the detection result of the infrared detection device.

[0059] For example, the infrared detection device is installed on the outer side of the housing of the outdoor unit of the air conditioner. The infrared detection device can detect whether there is a foreign object approaching the fixed grille 100 or the rotating grille 200. For example, whether a staff member's finger approaches the fixed grille 100 or the rotating grille 200, or whether a foreign object such as a bird approaches the fixed grille 100 or the rotating grille 200. Specifically, when the infrared detection device detects that there is a foreign object approaching the fixed grille 100 or the rotating grille 200, the control device controls the grille rotation driving device 300, so that the grille rotation driving device 300 drives the rotating grille 200 to switch to the second state, so as to reduce the air guiding area and block the foreign object from entering the outdoor unit of the air conditioner. When the infrared detection device detects that there is no foreign object approaching the fixed grille 100 or the rotating grille 200, the control device controls the grille rotation driving device 300, so that the grille rotation driving device 300 drives the rotating grille 200 to switch to the first state, so as to increase the air guiding area as much as possible.

[0060] Furthermore, in an embodiment of the present invention, when there is a foreign object approaching the fixed grille 100 or the rotating grille 200, the control device controls the grille rotation driving device 300, so that the rotating grille 200 switches to the second state.

[0061] The motor working state detection device is used to detect the working state of the fan motor 530, that is to say, the motor working state detection device is used to detect whether the fan motor 530 is in the running state or in the shutdown state. The control device controls the grille rotation driving device 300 based on the detection result of the motor working state detection device, so that the rotating grille 200 switches to the first state or the second state. Specifically, when there is a foreign object approaching the fixed grille 100 or the rotating grille 200, the control device controls the grille rotation driving device 300, so that the rotating grille 200 switches to the second state. When the fan motor 530 is shut down, the control device controls the grille rotation driving device 300, so that the rotating grille 200 switches to the second state. That is to say, when there is a foreign object approaching the fixed grille 100 or the rotating grille 200, or when the fan motor 530 is in the shutdown state, that is, when the outdoor unit of the air conditioner is in the shutdown state, the control device controls the grille rotation driving device 300, so that the rotating grille 200 rotates to the second state, reducing the ventilation area, protecting the outdoor unit of the air conditioner or the foreign object, and avoiding damaging the outdoor unit of the air conditioner or causing dangerous accidents.

[0062] In an embodiment of the present invention, a coil 610 is arranged at the outer end of the fixed shaft 130. A hollow cavity is arranged on the hub of the fan 520. An annular magnet 620 is connected in the hollow cavity. The fixed shaft 130 extends into the hollow cavity, so that the annular magnet 620 is arranged around the outside of the coil 610. The air outlet assembly for the outdoor unit of the air conditioner further includes a power storage device. The coil 610 is connected to the power storage device, and the power storage device is connected to the grille motor.

[0063] For example, as Figure 2 shown, a hollow cavity is provided at the hub center position of the fan 520, and an annular magnet 620 is provided in the hollow cavity. The fixed shaft 130 of the fixed grille 100 extends into the hollow cavity and passes through the center of the annular magnet 620. A coil 610 is provided on the fixed shaft 130, and the coil 610 is located inside the annular magnet 620. The coil 610 is connected to the power storage device, and the power storage device is connected to the grille motor. When the outdoor unit of the air conditioner stops running, the natural wind can drive the fan 520 to rotate. During the rotation of the fan 520, electricity will be generated in the coil 610 and can be stored in the power storage device. When the grille motor needs to work, the power storage device can provide power for it to achieve the energy-saving effect. For example, the power storage device includes a rechargeable battery.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
