Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to a deflector vane and an air conditioner. Background Art

[0002] At present, with the increasing improvement of living standards, air conditioners have become an indispensable household appliance in thousands of households. An air conditioner includes an indoor unit and an outdoor unit. Among them, the indoor unit is installed indoors, and the outdoor unit is installed outdoors. The indoor unit and the outdoor unit work together to achieve the function of regulating the indoor temperature. The outdoor unit generally dissipates heat through deflector vanes. However, the current deflector vanes have a small area for doing work on the air during operation, resulting in a small air volume, poor air outlet effect, and poor user experience. Summary of the Invention

[0003] The problem solved by the present invention is how to increase the area of the deflector vane doing work on the air during operation, increase the air volume, improve the air outlet effect, and enhance the user experience.

[0004] To solve the above problems, the technical solution of the present invention is realized as follows:

[0005] In a first aspect, the present invention provides a deflector vane, which includes a hub and a plurality of blade bodies. The blade bodies are strip-shaped and extend in a swirling shape. Both ends of the plurality of blade bodies are connected to the circumferential surface of the hub. The blade body has a tip point, and the distance between the tip point and the axis of the hub is the maximum distance between the blade body and the axis of the hub in the radial direction of the hub. The tip points of the plurality of blade bodies are arranged out of alignment in the axial direction of the hub. Compared with the prior art, the deflector vane provided by the present invention can increase the area of the deflector vane doing work on the air during operation, increase the air volume, improve the air outlet effect, and enhance the user experience because it adopts blade bodies that extend in a swirling shape and are connected to the circumferential surface of the hub at both ends, and the tip points of the plurality of blade bodies are arranged out of alignment.

[0006] Further, the distance between the tip points of any two blade bodies in the axial direction of the hub ranges from 10 mm to 110 mm. A reasonable distance between the tip points of any two blade bodies in the axial direction of the hub can improve the complementary effect of the plurality of blade bodies, further increase the contact area between the plurality of blade bodies and the air during rotation, and thus increase the area of the deflector vane doing work on the air during operation.

[0007] Further, the distance between the tip point and the axis of the hub ranges from 180 mm to 220 mm. By limiting the distance between the tip point and the axis of the hub, the outer diameter size of the entire deflector vane can be controlled to make it suitable for different models of outdoor air conditioners, ensuring that different models of outdoor air conditioners have good air outlet effects and low wind noise.

[0008] Furthermore, the distance between the tip point and the hub axis is 203 millimeters. A reasonable distance between the tip point and the hub axis can minimize wind noise while ensuring the air volume, thus improving the air outlet effect.

[0009] Furthermore, the number of blade bodies is even and at least four. Multiple blade bodies are all arranged on the circumferential surface of the hub, and the angle between any two adjacent blade bodies in the circumferential direction of the hub is equal. This can ensure the balance of the guiding blades during rotation and improve the stability of the guiding blades during operation.

[0010] Furthermore, multiple blade bodies are divided into two groups. Multiple blade bodies in each group are arranged adjacent to each other in sequence, and the tip points of multiple blade bodies in each group are arranged staggeredly in the axial direction of the hub. That is, the tip points of multiple blade bodies in each group increase or decrease in height in sequence in the axial direction of the hub, which can further improve the stability of the guiding blades during operation and thus enhance the air outlet effect.

[0011] Furthermore, the tip points of multiple blade bodies are arranged staggeredly alternately in the axial direction of the hub. That is, the height of the tip point of any one blade body in the axial direction of the hub is simultaneously higher or lower than the heights of the tip points of the two adjacent blade bodies in the axial direction of the hub, which can also ensure the stability of the guiding blades during operation and enhance the air outlet effect.

[0012] Furthermore, a first blade root is arranged at one end of the blade body, and a second blade root is arranged at the other end. Both the first blade root and the second blade root are connected to the circumferential surface of the hub. The first blade roots of multiple blade bodies are arranged staggeredly alternately in the axial direction of the hub, and the second blade roots of multiple blade bodies are arranged staggeredly alternately in the axial direction of the hub. The six blade bodies work together to further enhance the complementary function of the area passed through during rotation, thereby increasing the working area of the guiding blades, increasing the air volume, and improving the air outlet effect.

[0013] Furthermore, the two ends of the blade body are arranged at intervals, and the blade body and the hub jointly enclose a guiding cavity. The guiding cavity is used for air to pass through. On the one hand, it can increase the air volume of the entire guiding blade and improve the efficiency of the wind blade. On the other hand, it can play a noise reduction role and greatly reduce wind noise.

[0014] In a second aspect, the present invention provides an air conditioner, which includes a driving motor and the above-mentioned air guide vane. The air guide vane includes a hub and a plurality of blade bodies. The driving motor is connected to the hub. The blade bodies are strip-shaped and extend in a swirling manner. Both ends of the plurality of blade bodies are connected to the circumferential surface of the hub. Each blade body has a tip point, and the distance between the tip point and the axis of the hub is the maximum distance between the blade body and the axis of the hub in the radial direction of the hub. The tip points of the plurality of blade bodies are arranged in a staggered manner in the axial direction of the hub. The air conditioner can increase the working area of the air guide vane on the air during operation, increase the air volume, improve the air outlet effect, and enhance the user experience.

[0020] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0021] First Embodiment

[0022] Please refer to Figures 1 to 3 , the embodiment of the present invention provides an air guide vane 100 for driving air flow. It can increase the working area of the air guide vane 100 on the air during operation, increase the air volume, improve the air outlet effect, and enhance the user experience.

[0023] It should be noted that the air guiding vane 100 is applied to an outdoor unit of an air conditioner (not shown in the figure). The outdoor unit of the air conditioner is installed outdoors and connected to an indoor unit of the air conditioner (not shown in the figure). The outdoor unit and the indoor unit of the air conditioner work together to achieve the function of regulating the indoor temperature. The outdoor unit of the air conditioner includes a condenser (not shown in the figure), a driving motor (not shown in the figure), and a housing (not shown in the figure). Among them, the condenser, the driving motor, and the air guiding vane 100 are all arranged inside the housing, and the housing is used to shield and protect the condenser, the driving motor, and the air guiding vane 100. The driving motor is connected to the air guiding vane 100 to drive the air guiding vane 100 to rotate. The position of the air guiding vane 100 corresponds to the position of the condenser, and the condenser is used to exchange heat for the refrigerant. The air guiding vane 100 can form a negative pressure during the rotation process to drive the air flow to form an air outlet flow, and the air outlet flow is used to air-cool the condenser to take away the heat of the condenser and ensure the normal operation of the condenser.

[0024] The air guiding vane 100 includes a hub 110 and a blade body 120. The hub 110 is cylindrical, and the blade body 120 is fixedly connected to the circumferential surface of the hub 110. The hub 110 is used to drive the blade body 120 to rotate, and the blade body 120 can generate a negative pressure during the rotation process to drive the air flow. The hub 110 is connected to the driving motor, and the driving motor can drive the blade body 120 to rotate through the hub 110.

[0025] It is worth noting that the blade body 120 is strip-shaped. If the blade body 120 is straightened, the entire blade body 120 is in the shape of a rectangular strip. In this embodiment, the blade body 120 extends in a swirling manner, and both ends of the blade body 120 are connected to the circumferential surface of the hub 110. Specifically, the shape of the blade body 120 is described in detail in a dynamic manner: One end of the blade body 120 is connected to the circumferential surface of the hub 110 and extends away from the hub 110. When the blade body 120 extends to a certain length, the blade body 120 twists back (the twisting angle is approximately 180 degrees) and extends towards the hub 110 until the other end of the blade body 120 is connected to the circumferential surface of the hub 110.

[0026] Furthermore, the number of the blade bodies 120 is multiple, and the multiple blade bodies 120 are arranged on the circumferential surface of the hub 110 in a circular array with the axis of the hub 110 as the center. Both ends of the multiple blade bodies 120 are connected to the circumferential surface of the hub 110, and the multiple blade bodies 120 work together to increase the air outlet volume.

[0027] Specifically, the two ends of the blade body 120 are spaced apart and are both connected to the circumferential surface of the hub 110. The blade body 120 and the hub 110 together enclose an air guiding cavity 130 for air to pass through. During the rotation of the air guiding blade 100 driven by the driving motor, the blade body 120 agitates the air to form a negative pressure. During this process, the first part of the air passes through the gap between two adjacent blade bodies 120, and the second part of the air passes through the air guiding cavity 130. Both parts of the air flow along the air outlet direction under the pressure of the blade body 120. Compared with the prior art solution where the air conditioner outdoor unit fan can only drive the air to pass through the gap between two adjacent blades, the second part of the air passing through the air guiding cavity 130 in the present invention can, on the one hand, increase the air output of the entire air guiding blade 100 and improve the blade efficiency, and on the other hand, can play a sound absorption role after converging with the first part of the air, greatly reducing the wind noise.

[0028] It should be noted that the blade body 120 has a tip point 121. The distance between the tip point 121 and the axis of the hub 110 is the maximum distance between the axis of the blade body 120 and the axis of the hub 110 in the radial direction of the hub 110, that is, the tip point 121 is the end point on the blade body 120 with the longest straight-line distance from the hub 110, that is, the end point on the blade body 120 farthest from the hub 110. The blade body 120 is twisted at the position of the tip point 121 so that both ends of the blade body 120 are connected to the circumferential surface of the hub 110. Specifically, the tip points 121 of multiple blade bodies 120 are staggeredly arranged in the axial direction of the hub 110, that is, the projections of multiple tip points 121 in the axial direction of the hub 110 are staggeredly arranged. In this way, the twisting positions of multiple blade bodies 120 are different from each other in the axial direction of the hub 110, and the areas passed by multiple blade bodies 120 during rotation are complementary, so as to increase the contact area between multiple blade bodies 120 and the air during rotation, thereby increasing the work area of the air guiding blade 100 on the air during operation, increasing the air output, improving the air outlet effect, and enhancing the user experience.

[0029] Furthermore, the distance range between the tip points 121 of any two blade bodies 120 in the axial direction of the hub 110 is 10 millimeters to 110 millimeters. A reasonable distance between the tip points 121 of any two blade bodies 120 in the axial direction of the hub 110 can improve the complementary effect of multiple blade bodies 120, and further increase the contact area between multiple blade bodies 120 and the air during rotation, thereby increasing the work area of the air guiding blade 100 on the air during operation.

[0030] It should be noted that the number of blade bodies 120 is an even number and at least four. A plurality of blade bodies 120 are all arranged on the circumferential surface of the hub 110, and the included angle between any two adjacent blade bodies 120 in the circumferential direction of the hub 110 is equal, so as to ensure the balance of the guiding vane 100 during the rotation process and improve the stability of the operation of the guiding vane 100.

[0031] In this embodiment, the number of blade bodies 120 is six, and the included angle between any two adjacent blade bodies 120 in the circumferential direction of the hub 110 is 60 degrees, that is, the six blade bodies 120 are arranged on the circumferential surface of the hub 110 in a circular array. The hub 110 can drive the six blade bodies 120 to rotate simultaneously, so that the air flows to form an air outlet flow. However, it is not limited thereto. In other embodiments, the number of blade bodies 120 can be four or eight, and the number of blade bodies 120 is not specifically limited.

[0032] In this embodiment, a plurality of blade bodies 120 are divided into two groups. The plurality of blade bodies 120 in each group are arranged adjacent to each other in sequence, and the tip points 121 of the plurality of blade bodies 120 in each group are arranged in a staggered manner in the axial direction of the hub 110, that is, the tip points 121 of the plurality of blade bodies 120 in each group are successively increased or decreased in height in the axial direction of the hub 110. In this way, the stability of the guiding vane 100 during the operation process can be further improved, thereby enhancing the air outlet effect. However, it is not limited thereto. In other embodiments, the tip points of the plurality of blade bodies 120 are arranged in an alternating staggered manner in the axial direction of the hub 110, that is, the height of the tip point 121 of any one blade body 120 in the axial direction of the hub 110 is simultaneously higher or lower than the heights of the tip points 121 of the two adjacent blade bodies 120 in the axial direction of the hub 110, which can also ensure the stability of the guiding vane 100 during the operation process and enhance the air outlet effect.

[0033] Further, the six blade bodies 120 are divided into two groups. The three blade bodies 120 in each group are arranged adjacent to each other in sequence, and the tip points 121 of the three blade bodies 120 in each group are arranged in a staggered manner in the axial direction of the hub 110. Among them, the first group of blade bodies 120 includes the first blade body 120, the second blade body 120, and the third blade body 120, and the heights of the tip points 121 of the first blade body 120, the second blade body 120, and the third blade body 120 in the axial direction of the hub 110 are successively decreased; the second group of blade bodies 120 includes the fourth blade body 120, the fifth blade body 120, and the sixth blade body 120, and the heights of the tip points 121 of the fourth blade body 120, the fifth blade body 120, and the sixth blade body 120 in the axial direction of the hub 110 are also successively decreased.

[0034] Specifically, the distance between the tip point 121 of the first blade body 120 and the tip point 121 of the second blade body 120 in the axial direction of the hub 110 is 50 mm. The distance between the tip point 121 of the second blade body 120 and the tip point 121 of the third blade body 120 in the axial direction of the hub 110 is 30 mm. The distance between the tip point 121 of the third blade body 120 and the tip point 121 of the fourth blade body 120 in the axial direction of the hub 110 is 60 mm. The distance between the tip point 121 of the fourth blade body 120 and the tip point 121 of the fifth blade body 120 in the axial direction of the hub 110 is 10 mm. The distance between the tip point 121 of the fifth blade body 120 and the tip point 121 of the sixth blade body 120 in the axial direction of the hub 110 is 70 mm. The distance between the tip point 121 of the sixth blade body 120 and the tip point 121 of the first blade body 120 in the axial direction of the hub 110 is 100 mm. For the sake of easy understanding, the distance between the tip point 121 of the first blade body 120 and the tip point 121 of the second blade body 120 in the axial direction of the hub 110 is denoted as A, the distance between the tip point 121 of the second blade body 120 and the tip point 121 of the third blade body 120 in the axial direction of the hub 110 is denoted as B, the distance between the tip point 121 of the third blade body 120 and the tip point 121 of the fourth blade body 120 in the axial direction of the hub 110 is denoted as C, the distance between the tip point 121 of the fourth blade body 120 and the tip point 121 of the fifth blade body 120 in the axial direction of the hub 110 is denoted as D, the distance between the tip point 121 of the fifth blade body 120 and the tip point 121 of the sixth blade body 120 in the axial direction of the hub 110 is denoted as E, and the distance between the tip point 121 of the sixth blade body 120 and the tip point 121 of the first blade body 120 in the axial direction of the hub 110 is denoted as F.

[0035] It should be noted that a first blade root 122 is provided at one end of the blade body 120, and a second blade root 123 is provided at the other end. Both the first blade root 122 and the second blade root 123 are connected to the circumferential surface of the hub 110. The first blade root 122 and the second blade root 123 act together to fix the relative positions of the blade body 120 and the hub 110 and prevent the blade body 120 from detaching from the hub 110.

[0036] In this embodiment, the first blade roots 122 of the six blade bodies 120 are alternately offset in the axial direction of the hub 110, that is, the height of the first blade root 122 of any one blade body 120 in the axial direction of the hub 110 is simultaneously higher or lower than the heights of the first blade roots 122 of the two adjacent blade bodies 120 in the axial direction of the hub 110. Correspondingly, the second blade roots 123 of the six blade bodies 120 are alternately offset in the axial direction of the hub 110, that is, the height of the second blade root 123 of any one blade body 120 in the axial direction of the hub 110 is simultaneously higher or lower than the heights of the second blade roots 123 of the two adjacent blade bodies 120 in the axial direction of the hub 110. In this way, the torsional positions of the six blade bodies 120 are different from each other in the axial direction of the hub 110, and the six blade bodies 120 act together to further enhance the complementary function of the area passed through during rotation, thereby increasing the working area of the air guiding blade 100, increasing the air output, and improving the air output effect.

[0037] Furthermore, the distance between the tip point 121 and the axis of the hub 110 ranges from 180 mm to 220 mm. By limiting the distance between the tip point 121 and the axis of the hub 110, the outer diameter size of the entire air guiding blade 100 can be controlled to adapt to different models of air conditioner outdoor units, ensuring that different models of air conditioner outdoor units all have good air output effects and low wind noise. For the sake of easy understanding, the distance between the tip point 121 and the axis of the hub 110 is denoted as G.

[0038] In this embodiment, the distance between the tip point 121 and the axis of the hub 110 is 203 mm. A reasonable distance between the tip point 121 and the axis of the hub 110 can minimize the wind noise while ensuring the air output and improve the air output effect. However, it is not limited to this. In other embodiments, the distance between the tip point 121 and the axis of the hub 110 can be 180 mm or 220 mm, and the size of the distance between the tip point 121 and the axis of the hub 110 is not specifically limited.

[0039] In the embodiment of the present invention, for the air guiding vane 100, the blade body 120 is strip-shaped and extends in a swirling shape. Both ends of a plurality of blade bodies 120 are connected to the circumferential surface of the hub 110. The blade body 120 has a tip point 121. The distance between the tip point 121 and the axis of the hub 110 is the maximum distance between the axis of the blade body 120 and the axis of the hub 110 in the radial direction of the hub 110. The tip points 121 of a plurality of blade bodies 120 are arranged in a staggered manner in the axial direction of the hub 110. Compared with the prior art, since the air guiding vane 100 provided by the present invention adopts the blade body 120 that extends in a swirling shape and both ends are connected to the circumferential surface of the hub 110 and the tip points 121 of a plurality of blade bodies 120 arranged in a staggered manner, the working area of the air guiding vane 100 on the air during operation can be increased, the air output can be increased, the air output effect can be improved, and the user experience can be enhanced.
