[0022] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0023] First Embodiment

[0024] Please refer to the reference. Figure 1 and Figure 2 This invention provides an air guide impeller 100 for driving airflow. It improves the structural stability of the air guide impeller 100, prevents deformation, ensures airflow and heat exchange efficiency, and reduces noise.

[0025] It should be noted that the air guide impeller 100 is used in the outdoor unit of an air conditioner (not shown). The outdoor unit is installed outdoors and connected to the indoor unit (not shown). The outdoor and indoor units work together to regulate the indoor temperature. The outdoor unit includes a condenser (not shown), a drive motor (not shown), and a casing (not shown). The condenser, drive motor, and air guide impeller 100 are all installed inside the casing. The drive motor is connected to the air guide impeller 100 to drive its rotation. The position of the air guide impeller 100 corresponds to the position of the condenser, which is used for heat exchange with the refrigerant. The air guide impeller 100 can generate negative pressure during rotation, driving airflow to form an exhaust airflow. This exhaust airflow is used to cool the condenser, removing heat and ensuring its normal operation.

[0026] The air guide impeller 100 includes blades 120, a boss 130, and a hub 110. The hub 110 is cylindrical, and the blades 120 are fixedly connected to the circumferential surface of the hub 110. The hub 110 can drive the blades 120 to rotate, thereby driving airflow. The hub 110 is used to connect to a drive motor, which can drive the blades 120 to rotate via the hub 110. The boss 130 is fixedly connected to the side of the blades 120 away from the hub 110. The thickness of the boss 130 is greater than the thickness of the blades 120. The boss 130 is used to thicken the side of the blades 120 away from the hub 110 to improve the structural stability of the air guide impeller 100, prevent deformation of the air guide impeller 100, ensure airflow and heat exchange efficiency, and reduce noise.

[0027] In this embodiment, there are three blades 120 arranged in a circular array on the circumference of the hub 110. The hub 110 can simultaneously drive the three blades 120 to rotate, thereby creating an airflow. However, this is not the only embodiment. In other embodiments, the number of blades 120 can be four or five, and the number of blades 120 is not specifically limited.

[0028] Please refer to the reference. Figure 3 , Figure 4 and Figure 5It should be noted that the blade 120 is provided with a leading edge 121, a trailing edge 122, an inner edge 123, and an outer edge 124. The leading edge 121 and the trailing edge 122 are arranged opposite each other, and the inner edge 123 and the outer edge 124 are arranged opposite each other. The leading edge 121, the outer edge 124, the trailing edge 122, and the inner edge 123 are connected end to end to form the outline shape of the blade 120. Specifically, the inner edge 123 is the side of the blade 120 that connects to the hub 110, the outer edge 124 is the side of the blade 120 away from the hub 110, the leading edge 121 is the side of the blade 120 facing the wind during rotation, and the trailing edge 122 is the side of the blade 120 on the leeward side during rotation.

[0029] Furthermore, the inner edge 123 is fixedly connected to the hub 110, and the outer edge 124 is fixedly connected to the boss 130. The boss 130 is arranged along the extension direction of the outer edge 124, that is, the extension direction of the boss 130 is the same as the extension direction of the outer edge 124, and the boss 130 is located on the side of the outer edge 124 away from the inner edge 123. Specifically, since the outer edge 124 of the blade 120 is subjected to the greatest force and is most prone to deformation during the rotation of the wind guide impeller 100, in this embodiment, the boss 130 can reinforce the shape of the outer edge 124, improve the stability of the blade 120 structure, and prevent the outer edge 124 from deforming, which is practical and reliable.

[0030] It is worth noting that the ratio of the thickness of the blade 120 to the thickness of the boss 130 is in the range of 0.7 to 0.8. A reasonable ratio of the thickness of the blade 120 to the thickness of the boss 130 can be used to reasonably set the thickness of the boss 130 according to the thickness of the blade 120, so that the thickness of the boss 130 matches the thickness of the blade 120 and improves the stability of the blade 120 structure.

[0031] In this embodiment, the ratio of the thickness of the blade 120 to the thickness of the boss 130 is 0.75, but it is not limited to this. In other embodiments, the ratio of the thickness of the blade 120 to the thickness of the boss 130 can be 0.7 or 0.8. There is no specific limitation on the size of the ratio of the thickness of the blade 120 to the thickness of the boss 130.

[0032] Specifically, the thickness of the boss 130 ranges from 2.5 mm to 4 mm. A reasonable thickness of the boss 130 can minimize the material consumption of the boss 130 while ensuring the structural stability of the blade 120, thereby reducing material costs and lightening the weight of the guide impeller 100.

[0033] In this embodiment, the thickness of the boss 130 is 3 mm, but it is not limited to this. In other embodiments, the thickness of the boss 130 can be 2 mm or 4 mm. The thickness of the boss 130 is not specifically limited.

[0034] It should be noted that the width of the boss 130 ranges from 8 mm to 10 mm. A reasonable width of the boss 130 can further improve the strength of the outer edge 124, prevent the outer edge 124 from deforming, and thus improve the stability of the blade 120 structure.

[0035] In this embodiment, the width of the boss 130 is 9 mm, but it is not limited to this. In other embodiments, the width of the boss 130 can be 8 mm or 10 mm. The width of the boss 130 is not specifically limited.

[0036] For ease of understanding, the thickness of the boss 130 is denoted as H, the thickness of the blade 120 is denoted as h, and the width of the boss 130 is denoted as L.

[0037] In this embodiment, both the outer edge 124 and the boss 130 are arc-shaped. The center of the arc of the outer edge 124 coincides with the midpoint of the hub 110 to ensure air volume and heat exchange efficiency.

[0038] It is worth noting that the blades 120 are provided with a windward side 125 and a leeward side 126. One side of the boss 130 is flush with the windward side 125, and the other side of the boss 130 protrudes from the leeward side 126 to prevent the boss 130 from affecting the airflow and to ensure the air volume and heat exchange efficiency. Specifically, the blades 120 drive the airflow during rotation to form an exhaust airflow. The exhaust airflow is directed from the windward side 125 to the leeward side 126. When the exhaust airflow flows along the exhaust direction onto the windward side 125, since the boss 130 is flush with the windward side 125, the boss 130 will not affect the exhaust airflow.

[0039] It should be noted that the trailing edge 122 has a recessed notch 127 facing the leading edge 121. The notch 127 can reduce the weight of the guide impeller 100, reduce material costs, and reduce energy consumption. Specifically, there are multiple notches 127, which are continuously arranged on the trailing edge 122. The multiple notches 127 work together to further reduce the weight of the guide impeller 100, reduce material costs, and reduce energy consumption.

[0040] In this embodiment, there are three notches 127. The three notches 127 are combined to form a wave shape. The wave-shaped notches 127 can minimize the noise generated by the rotation of the air guide impeller 100 while ensuring the air volume, thus improving the user experience. However, it is not limited to this. In other embodiments, the number of notches 127 can be two or four. The number of notches 127 is not specifically limited.

[0041] In this embodiment, the blade 120 is provided with a reinforcing rib 128, which is fixedly connected to the hub 110. The reinforcing rib 128 can improve the strength of the blade 120, prevent the blade 120 from deforming or bending relative to the hub 110, and further improve the stability of the wind guide impeller 100 structure.

[0042] The air guide impeller 100 of this embodiment has blades 120 with an inner edge 123 and an outer edge 124 oppositely arranged. The inner edge 123 is fixedly connected to the hub 110, and the outer edge 124 is fixedly connected to a boss 130. The boss 130 is arranged along the extending direction of the outer edge 124, and the thickness of the boss 130 is greater than the thickness of the blades 120. Compared with the prior art, the air guide impeller 100 provided by this invention, due to the use of a boss 130 fixedly connected to the outer edge 124 and arranged along the extending direction of the outer edge 124, can improve the structural stability of the air guide impeller 100, avoid deformation of the air guide impeller 100, ensure air volume and heat exchange efficiency, and reduce noise.
