Description

Technical Field

[0001] The present application belongs to the technical field of air conditioning, and in particular, relates to an air outlet grille, an air conditioning outdoor unit and an air conditioner. Background Art

[0002] The air outlet of the air conditioner outdoor unit is generally equipped with an air outlet grille for air flow rectification and safety protection. The air outlet grille includes staggered transverse ribs and horizontal ribs. When the axial flow fan inside the air conditioner outdoor unit rotates at high speed, it will generate airflow with a centrifugal effect. The airflow will eventually blow out of the air conditioner outdoor unit through the air outlet grille. However, when the airflow passes through the air outlet grille, there is still a centripetal rotation angle, so it will be resisted by the transverse ribs and vertical ribs, resulting in air volume loss and increased noise of the air conditioner outdoor unit.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined

[0028] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or demonstration". Any embodiment described as "exemplary" in this application is not necessarily to be construed as more preferred or advantageous than other embodiments.

[0029] An embodiment of this application provides an air outlet grille 100, which can be applied to an outdoor unit of an air conditioner.

[0030] As Figures 1 to 6 shown, the air outlet grille 100 provided by the embodiment of this application includes a plurality of horizontal ribs 110 and a plurality of vertical ribs 120, and the horizontal ribs 110 and the vertical ribs 120 are arranged intersectingly; the air guiding surface 121 of the vertical rib 120 is a torsional surface, and the torsional directions of the upper half air guiding surface 121 and the lower half air guiding surface 121 of the vertical rib 120 with the horizontal central axis of the air outlet grille 100 as the boundary are opposite; as Figure 7 shown, the included angle between the air guiding surface 121 of the vertical rib 120 and the vertical plane is the torsional angle α, and the torsional angles α at both ends of the vertical rib 120 are between 15° and 45°.

[0031] Wherein, the included angle between the air guiding surface 121 of the vertical rib 120 and the vertical plane is the included angle between the tangent plane of the air guiding surface 121 and the vertical plane, and the included angle between the tangent plane of any point on the air guiding surface 121 of the vertical rib 120 and the horizontal plane is the torsional angle α.

[0032] Exemplarily, the torsional angles α at both ends of the vertical rib 120 can be 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°, etc., and can be specifically set according to actual requirements.

[0033] For the air outlet grille 100 provided by the embodiment of this application, by setting the air guiding surface 121 of the vertical rib 120 as a torsional surface, and the torsional directions of the upper half air guiding surface 121 and the lower half air guiding surface 121 of the vertical rib 120 with the horizontal central axis of the air outlet grille 100 as the boundary are opposite, and the torsional angles α at both ends of the vertical rib 120 are between 15° and 45°, when the air flow with a centripetal rotation angle passes through the vertical rib 120, the air guiding surface 121 of the vertical rib 120 can make the air flow deflect along its centripetal angular velocity direction, so that the resistance of the vertical rib 120 to the air flow of the air outlet can be reduced, and further the loss of the air volume of the outdoor unit of the air conditioner can be reduced, and the air outlet noise of the outdoor unit of the air conditioner can also be reduced.

[0034] Optionally, as Figures 1 to 5As shown, the torsion angle α gradually decreases from both ends of the vertical rib 120 to the middle of the vertical rib 120, and the torsion angle α at the middle of the vertical rib 120 is 0°. When the air flow with a centripetal rotation angle passes through the vertical rib 120, from the axis of the air outlet grille 100 to the edge direction, the larger the centripetal angle of the air flow, so that the torsion angle α changes in the same way as the centripetal angle of the air flow, further reducing the resistance to the air outlet flow.

[0035] Optionally, the upper half and the lower half of the vertical rib 120 symmetrically arranged with the horizontal central axis of the air outlet grille 100 as the boundary. For the convenience of understanding, the upper half and the lower half of the vertical rib 120 with the horizontal central axis of the air outlet grille 100 as the boundary are respectively defined as the upper torsion part and the lower torsion part, and the torsion angles α of the symmetric points of the upper torsion part and the lower torsion part are equal. By symmetrically arranging the upper half and the lower half of the vertical rib 120 with the horizontal central axis of the air outlet grille 100 as the boundary, the resistance of the upper half and the lower half of the air outlet grille 100 to the air outlet flow is the same, so as to achieve the balance of the forces on the upper half and the lower half of the air outlet grille 100 and it is not easy to have a failure.

[0036] Optionally, as Figure 7 shown, the vertical rib 120 has an air inlet side 122 and an air outlet side 123, and the thickness of the vertical rib 120 gradually increases along the direction from its air inlet side 122 to its air outlet side 123. In this way, the thickness of the air inlet side 122 of the vertical rib 120 is smaller than the thickness of its air outlet side 123, so that the wind resistance on the windward side of the vertical rib 120 can be reduced and the air outlet noise can be lowered.

[0037] Optionally, there are multiple horizontal ribs 110 and multiple vertical ribs 120. The multiple horizontal ribs 110 are arranged in parallel, the multiple vertical ribs 120 are arranged in parallel, and the distance between adjacent two horizontal ribs 110 is greater than the distance between adjacent two vertical ribs 120. In this way, on the premise of ensuring the structural stability, the number of the horizontal ribs 110 can be reduced, so as to reduce the resistance of the horizontal ribs 110 to the air outlet flow, and further reduce the loss of the air outlet volume of the air conditioner outdoor unit, and also reduce the air outlet noise of the air conditioner outdoor unit.

[0038] In some embodiments of the present application, the air outlet grille 100 further includes a frame 130, and the horizontal ribs 110 and the vertical ribs 120 are arranged on the frame 130. By providing the frame 130, it is convenient to install the air outlet grille 100 on an external device, for example, to install the air outlet grille 100 on the housing 200 of the air conditioner outdoor unit.

[0039] The embodiments of the present application also provide an air conditioner outdoor unit, as Figure 8As shown in the figure, the outdoor unit of the air conditioner includes a housing 200, an axial flow fan 300, and an air outlet grille 100. The axial flow fan 300 is arranged inside the housing 200. The housing 200 is provided with an air outlet, and the air outlet grille 100 is arranged at the air outlet. The specific structure of the air outlet grille 100 refers to the above-mentioned embodiment.

[0040] Since the outdoor unit of this air conditioner adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.

[0041] Among them, the axial flow fan 300 may include a blade and a driving member, and the driving member can drive the blade to rotate. It should be noted that the installation of the axial flow fan 300 should correspond to the torsion direction of the vertical rib 120. When the driving member is configured to drive the blade to rotate clockwise, from the air outlet direction, the upper half of the vertical rib 120 is twisted obliquely to the right, and the lower half of the vertical rib 120 is twisted obliquely to the left. In this way, the torsion direction of the air guiding surface 121 of the vertical rib 120 can be the same as the centripetal angular velocity direction of the air outlet airflow, so as to realize the inclined diversion of the air outlet airflow along its centripetal angular velocity direction, reduce the resistance of the vertical rib 120 to the air outlet airflow, and further reduce the loss of the air outlet volume of the outdoor unit of the air conditioner, and also reduce the air outlet noise of the outdoor unit of the air conditioner.

[0042] Combined with Figures 1 to 8 As shown in the figure, when the driving member is configured to drive the blade to rotate counterclockwise, from the air outlet direction, the upper half of the vertical rib 120 is twisted obliquely to the left, and the lower half of the vertical rib 120 is twisted obliquely to the right. In this way, the torsion direction of the air guiding surface 121 of the vertical rib 120 can be the same as the centripetal angular velocity direction of the air outlet airflow, so as to realize the inclined diversion of the air outlet airflow along its centripetal angular velocity direction, reduce the resistance of the vertical rib 120 to the air outlet airflow, and further reduce the loss of the air outlet volume of the outdoor unit of the air conditioner, and also reduce the air outlet noise of the outdoor unit of the air conditioner.

[0043] Optionally, the driving member can be a motor. To facilitate the installation of the driving member inside the housing 200, the outdoor unit of the air conditioner may further include a bracket 400. The bracket 400 is arranged inside the housing 200. The bracket 400 can be fixed to the housing 200 through structures such as screws or buckles, and the driving member is installed on the bracket 400.

[0044] Optionally, the outdoor unit of the air conditioner further includes an outdoor heat exchanger 500. The outdoor heat exchanger 500 is arranged inside the housing 200, and the outdoor heat exchanger 500 is located on the air inlet side of the axial flow fan 300, and the air outlet grille 100 is located on the air outlet side of the axial flow fan 300.

The specific structure of the outdoor unit of the air conditioner refers to the above embodiments. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. In the above embodiments, the descriptions of each embodiment have their own focuses. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0046] The above has introduced in detail the outlet grille, the outdoor unit of the air conditioner and the air conditioner provided by the embodiments of the present application.

The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope.
