Description

Technical Field

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

[0002] An air conditioner changes the air outlet angle by controlling the air deflector to rotate to different positions. For example, it can achieve the floor air (heating) mode and the sky curtain air (cooling) mode. In the related art, in the sky curtain air mode, eddy currents are likely to form near the air deflector, resulting in the problem of condensation on the air conditioner; in the floor air mode, the hot air flowing through the air deflector is difficult to quickly reach the ground, resulting in poor heating effect of the air conditioner. Utility Model Content

[0003] The present disclosure provides an air deflector to reduce the risk of condensation problems in the air conditioner and improve the heating effect of the air conditioner.

[0004] The air deflector of the present disclosure includes an air deflector body.

[0032] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure.

[0033] As Figure 1 and Figure 2 shown, the air deflector 10 of the embodiment of the present disclosure includes an air deflector body 1. The air deflector body 1 includes a first air guiding surface 11, a transitional air guiding surface 13, and a second air guiding surface 12 that are arranged in sequence along its width direction (the Y direction in the figure). At least a part of the first air guiding surface 11 is inclined relative to the transitional air guiding surface 13 in a direction away from the transitional air guiding surface 13, and at least a part of the second air guiding surface 12 is inclined relative to the transitional air guiding surface 13 in a direction away from the transitional air guiding surface 13.

[0034] Among them, at least a part of the first air guiding surface 11 being inclined relative to the transitional air guiding surface 13 in a direction away from the transitional air guiding surface 13 can be understood as: only a part of the first air guiding surface 11 is inclined relative to the transitional air guiding surface 13 in a direction away from the transitional air guiding surface 13; or, the entire first air guiding surface 11 is inclined relative to the transitional air guiding surface 13 in a direction away from the transitional air guiding surface 13. At least a part of the second air guiding surface 12 being inclined relative to the transitional air guiding surface 13 in a direction away from the transitional air guiding surface 13 can be understood as: only a part of the second air guiding surface 12 is inclined relative to the transitional air guiding surface 13 in a direction away from the transitional air guiding surface 13; or, the entire second air guiding surface 12 is inclined relative to the transitional air guiding surface 13 in a direction away from the transitional air guiding surface 13.

[0035] For example, the transition air guiding surface 13 is arranged on one side of the air guiding plate body 1 facing the thickness direction (the Z direction in the figure), at least a part of the first air guiding surface 11 is inclined relative to the transition air guiding surface 13 along the other side facing the thickness direction of the air guiding plate body 1, and at least a part of the second air guiding surface 12 is inclined relative to the transition air guiding surface 13 along the other side facing the thickness direction of the air guiding plate body 1. Wherein, the length direction of the air guiding plate body 1 is consistent with the X direction in the figure.

[0036] As Figure 5 shown, for the air conditioner 100 with the air guiding plate 10 of the embodiment of the present disclosure, in the sky curtain air mode, the air flow at the air outlet 201 flows to the first air guiding surface 11 under the guiding action of the transition air guiding surface 13, and the air flow is mainly guided by the first air guiding surface 11; in the floor air mode, the air flow at the air outlet 201 flows to the second air guiding surface 12 under the guiding action of the transition air guiding surface 13, and the air flow is mainly guided by the second air guiding surface 12. By arranging at least a part of the first air guiding surface 11 to be inclined relative to the transition air guiding surface 13 along the direction away from the transition air guiding surface 13, the eddy current formed by the air flow at the air guiding plate 10 can be reduced, thereby reducing the risk of condensation problems occurring in the air conditioner 100; by arranging at least a part of the second air guiding surface 12 to be inclined relative to the transition air guiding surface 13 along the direction away from the transition air guiding surface 13, the landing speed of the air flow passing through the air guiding plate 10 can be increased, and the heating effect of the air conditioner 100 can be improved.

[0037] Optionally, as Figure 2 shown, the transition air guiding surface 13 is an arc surface.

[0038] By setting the transition air guiding surface 13 as an arc surface, the flow resistance of the transition air guiding surface 13 to the air flow can be reduced, and the air volume of the air conditioner 100 can be increased.

[0039] In some embodiments, as Figure 2 and Figure 3 shown, the first air guiding surface 11 includes a first part 111 and a second part 112. The first part 111 is arranged between the second part 112 and the transition air guiding surface 13 in the width direction of the air guiding plate body 1. The first part 111 is smoothly connected to the transition air guiding surface 13, and the second part 112 is inclined relative to the transition air guiding surface 13 along the direction away from the transition air guiding surface 13.

[0040] It can be understood that the second part 112 is inclined relative to the transition air guiding surface 13 along the direction away from the transition air guiding surface 13, which is used to reduce the eddy current formed by the air flow at the air guiding plate 10 and reduce the risk of condensation problems occurring in the air conditioner 100.

[0041] When the air flow flows from the transition air guiding surface 13 to the first air guiding surface 11, it will first flow to the first part 111 of the first air guiding surface 11. By smoothly connecting the first part 111 with the transition air guiding surface 13, the flow resistance of the air flow from the transition air guiding surface 13 to the first air guiding surface 11 can be reduced, and the air volume of the air conditioner 100 can be increased.

[0042] In some other embodiments, the first air guiding surface 11 as a whole may also be arranged to be inclined relative to the transition air guiding surface 13 in a direction away from the transition air guiding surface 13.

[0043] Optionally, the included angle between the first part 111 and the second part 112 is 106° - 158°.

[0044] For example, as Figure 3 shown, the included angle between the first part 111 and the second part 112 is α, and α is 132°.

[0045] By setting the included angle between the first part 111 and the second part 112 to be 106° - 158°, the eddy current at the air deflector 10 in the sky curtain air mode can be effectively reduced, and the risk of the air conditioner 100 having condensation problems can be reduced.

[0046] Of course, in some other embodiments, the included angle between the first part 111 and the second part 112 may also be set to other angles outside the range of 106° - 158°.

[0047] Optionally, both the first part 111 and the second part 112 are planes.

[0048] By setting both the first part 111 and the second part 112 as planes, not only is it convenient for the processing and manufacturing of the air deflector 10, reducing the manufacturing cost of the air deflector 10; but also the eddy current at the air deflector 10 in the sky curtain air mode can be further reduced, and the risk of the air conditioner 100 having condensation problems can be reduced.

[0049] Of course, in some other embodiments, both the first part 111 and the second part 112 may also be set as arc surfaces; or, one of the first part 111 and the second part 112 is an arc surface, and the other is a plane.

[0050] Optionally, as Figures 1 to 3 shown, a fillet is provided between the first part 111 and the second part 112.

[0051] By providing a fillet between the first part 111 and the second part 112, the flow resistance of the air flow from the first part 111 to the second part 112 can be reduced, and the air volume of the air conditioner 100 can be increased.

[0052] In some embodiments, as Figure 2 and Figure 4As shown, the second air guiding surface 12 includes a third part 121 and a fourth part 122. The third part 121 is disposed between the fourth part 122 and the transition air guiding surface 13 in the width direction of the air guiding plate body 1. The third part 121 is smoothly connected to the transition air guiding surface 13, and the fourth part 122 is inclined relative to the transition air guiding surface 13 in a direction away from the transition air guiding surface 13.

[0053] It can be understood that the fourth part 122 is inclined relative to the transition air guiding surface 13 in a direction away from the transition air guiding surface 13, which is used to increase the landing speed of the air flow passing through the air guiding plate 10 and improve the heating effect of the air conditioner 100.

[0054] When the air flow flows from the transition air guiding surface 13 to the second air guiding surface 12, it will first flow to the third part 121 of the second air guiding surface 12. By smoothly connecting the third part 121 with the transition air guiding surface 13, the flow resistance of the air flow from the transition air guiding surface 13 to the second air guiding surface 12 can be reduced, and the air volume of the air conditioner 100 can be increased.

[0055] Optionally, the third part 121 is an arc surface, and the fourth part 122 is a plane surface.

[0056] As described above, when the air flow flows from the transition air guiding surface 13 to the second air guiding surface 12, it will first flow to the third part 121 of the second air guiding surface 12. By setting the third part 121 as an arc surface, the flow resistance of the air flow from the transition air guiding surface 13 to the second air guiding surface 12 can be further reduced, and the air volume of the air conditioner 100 can be increased. By setting the fourth part 122 as a plane surface, the landing speed of the air flow passing through the air guiding plate 10 in the landing air mode can be further increased, and the heating effect of the air conditioner 100 can be improved.

[0057] Optionally, the third part 121 is a concave arc surface.

[0058] Of course, in some other embodiments, both the third part 121 and the fourth part 122 can be set as arc surfaces; or, both the third part 121 and the fourth part 122 are set as plane surfaces; or, the third part 121 is set as a plane surface and the fourth part 122 is set as an arc surface.

[0059] Optionally, the radius of the third part 121 is 30 mm to 45 mm.

[0060] For example, as Figure 4 shown, the radius of the third part 121 is R, and R is 37 mm.

[0061] By setting the radius of the third part 121 to 30 mm to 45 mm, the landing speed of the air flow passing through the air guiding plate 10 in the landing air mode can be further increased, and the heating effect of the air conditioner 100 can be improved.

[0062] Optionally, the radian of the third part 121 is 18° to 28°.

[0063] For example, as Figure 4 shown, the radian of the third part 121 is β, and β is 23°.

[0064] By setting the radian of the third part 121 to 18° to 28°, the landing speed of the air flow passing through the air deflector 10 in the floor air mode can be further increased, and the heating effect of the air conditioner 100 can be improved.

[0065] Optionally, as Figure 1 , Figure 2 and Figure 4 shown, a fillet is provided between the third part 121 and the fourth part 122.

[0066] By providing a fillet between the third part 121 and the fourth part 122, the flow resistance of the air flow from the third part 121 to the fourth part 122 can be reduced, and the air volume of the air conditioner 100 can be increased.

[0067] Optionally, the included angle between the first part 111 and the fourth part 122 is 42° to 62°.

[0068] For example, as Figure 4 shown, the included angle between the first part 111 and the fourth part 122 is γ, and γ is 52°.

[0069] By setting the included angle between the first part 111 and the fourth part 122 to 42° to 62°, the landing speed of the air flow passing through the air deflector 10 in the floor air mode can be further increased, and the heating effect of the air conditioner 100 can be improved.

[0070] As Figure 1 and Figure 2 shown, the air deflector 10 further includes a spacer layer 3 and an outer air deflector plate 4, and the air deflector body 1 is connected to the outer air deflector plate 4 through the spacer layer 3.

[0071] For example, the spacer layer 3 is connected to the air deflector body 1 by a buckle, and the outer air deflector plate 4 is bonded to the spacer layer 3.

[0072] As Figure 5 shown, the air conditioner 100 of the embodiment of the present disclosure includes the air deflector 10 of any one of the above embodiments.

[0073] Due to the air deflector 10 of the embodiment of the present disclosure, the eddy current formed by the air flow at the air deflector 10 can be reduced, so that the risk of the air conditioner 100 having a condensation problem can be reduced; the landing speed of the air flow passing through the air deflector 10 can be increased, thereby improving the heating effect of the air conditioner 100. Thus, the performance of the air conditioner 100 of the embodiment of the present disclosure is better.

[0074] In some embodiments, such as Figure 5 shown, the air conditioner 100 is a wall-mounted air conditioner 100. The air conditioner 100 includes a housing 20. An air outlet 201 is provided at the front side of the housing 20 and near the upper side. The air deflector 10 is provided at the air outlet 201.

[0075] Among them, the air outlet 201 is provided at the front side of the housing 20 and near the upper side, that is, the air outlet of the air conditioner 100 is an upper air outlet.

[0076] During specific use, the first air deflector surface 11 is provided above the second air deflector surface 12. In the sky curtain wind mode, the air deflector 10 rotates until the first air deflector surface 11 is in front of the second air deflector surface 12, and the front end and the rear end of the air deflector 10 are generally at the same height. At this time, the airflow at the air outlet 201 is mainly guided by the first air deflector surface 11; in the floor wind mode, the air deflector 10 rotates until the second air deflector surface 12 is in front of the first air deflector surface 11, and the front end of the air deflector 10 is lower than the rear end of the air deflector 10. At this time, the airflow at the air outlet 201 is mainly guided by the second air deflector surface 12.

[0077] Such as Figure 6 and Figure 7 shown, by optimizing the design of the air deflector 10, the air conditioner 100 can reduce the eddy current formed at the front end of the air deflector 10 in the sky curtain wind mode, reducing the risk of condensation problems of the air conditioner 100; in the floor wind mode of the air conditioner 100, the hot air flow can quickly reach the ground, and the hot air flow is as close to a vertical angle with the ground as possible, ensuring that the hot air flow can reach the ground within one meter, improving the heating effect of the air conditioner 100.

[0078] Although the embodiments of the present disclosure have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present disclosure. Any changes, modifications, substitutions, and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present disclosure.
