[0037] To better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0038] As Figures 1 to 4As shown in the figure, according to the first aspect of the embodiments of the present application, a wind deflector 100 is provided, including: a wind deflector main body 110, the air outlet end of the wind deflector main body 110 is the first end, and the end corresponding to the air outlet end is the second end; an airfoil plate 120, disposed in the middle of the second end of the wind deflector main body 110, for accelerating the air flow flowing through the airfoil plate 120.

[0039] It can be understood that the wind deflector 100 provided in the embodiments of the present application is provided with a wind deflector main body 110 and an airfoil plate 120. Among them, the wind deflector main body 110 is rotatably disposed at the air outlet 240 of the ceiling unit 200 to change the blowing angle of the air outlet 240 by adjusting the angle of the wind deflector main body 110 relative to the air outlet 240. The air outlet end of the wind deflector main body 110 is set as the first end, and the end opposite to the air outlet end is the second end. The airfoil plate 120 can be disposed in the middle of the second end of the wind deflector main body 110. The shape of the airfoil plate 120 can accelerate the air flow flowing through the airfoil plate 120. In this way, the cold air formed by the ceiling unit 200 in the cooling mode is accelerated by the airfoil plate 120 and blown out from the air outlet 240, improving the air supply distance to blow the air flow to a farther place.

[0040] It should be noted that the airfoil plate 120 is disposed in the middle of the second end of the wind deflector main body 110. The length dimension of the airfoil plate 120 is smaller than the length dimension of the wind deflector main body 110, that is, there is a gap between the airfoil plate 120 and both ends of the wind deflector main body 110. When the air flow passes through the side of the airfoil plate 120 close to the second end, part of the air flow will continue to move forward along the surface of the airfoil plate 120. The surface of the airfoil plate 120 conforms to the accelerating effect of aerodynamics to accelerate this part of the air flow and blow it towards the air outlet 240, improving the air supply distance. Another part of the air flow will blow out from the air outlet 240 through the gap without passing through the accelerating effect of the airfoil plate 120 to flow to the area below the ceiling unit 200, so that the air flow acts on the indoor environment more evenly and ensures the temperature adjustment effect of the ceiling unit 200.

[0041] It can be understood that in the cooling condition of the ceiling unit 200 applying the wind deflector 100 of the embodiments of the present application, the cold air will be evenly distributed in the indoor environment under the action of the wind deflector 100 to ensure a uniform indoor environment temperature field. It avoids the situation that the cold air is heavier and falls to a smaller area below the ceiling unit 200, improving the user experience.

[0042] In some examples, as Figure 1 shown, the distance dimension between the end of the airfoil plate 120 close to the first end and the wind deflector main body 110 is smaller than the distance dimension between the end of the airfoil plate 120 close to the second end and the wind deflector main body 110.

[0043] It can be understood that the distance between one end of the airfoil plate 120 close to the second end and the air deflector main body 110 is the maximum value of the distance between the airfoil plate 120 and the air deflector main body 110. The airfoil plate 120 extends in the direction of the air outlet side with this distance dimension. At the position where the airfoil plate 120 is close to the first end, the distance between the airfoil plate 120 and the air deflector main body 110 gradually decreases, so that the distance between one end of the airfoil plate 120 close to the first end and the air deflector main body 110 is smaller than the distance between one end of the airfoil plate 120 close to the second end and the air deflector main body 110. Thus, the airfoil plate 120 is arranged to be narrowed towards the air outlet side of the air deflector main body 110, so that the shape of the airfoil plate 120 conforms to the aerodynamic acceleration model, thereby producing an acceleration effect on the air flow.

[0044] In some examples, the distance dimension between the airfoil plate 120 and the air deflector main body 110 is determined according to the width dimension of the air outlet 240 corresponding to the air deflector 100 and the rotation angle of the air deflector 100.

[0045] It can be understood that in order to ensure the adaptation between the air deflector 100 and the ceiling unit 200, the distance dimension between the airfoil plate 120 and the air deflector main body 110 can be determined according to the width dimension of the air outlet 240 and the rotation angle of the air deflector 100 relative to the air outlet 240. Specifically, taking Figure 5 the horizontal direction shown as the width direction of the air outlet 240 of the ceiling unit 200. Let the distance dimension between the airfoil plate 120 and the air deflector main body 110 be d; the width dimension of the air outlet 240 of the air deflector 100 be D; and the rotation angle of the air deflector 100 be θ. Then d = (5% - 10%) * D * sinθ. The distance dimension between one end of the airfoil plate 120 close to the second end and the air deflector main body 110 and the distance dimension between one end of the airfoil plate 120 close to the first end and the air deflector main body 110 both satisfy the above formula. Exemplarily, the distance dimension d1 between one end of the airfoil plate 120 close to the second end and the air deflector main body 110 is 6% * D * sinθ; the distance dimension d2 between one end of the airfoil plate 120 close to the first end and the air deflector main body 110 is 9% * D * sinθ. The distance dimension between the airfoil plate 120 and the air deflector 100 designed by the above formula can ensure that a certain amount of gas can enter the area formed by the airfoil plate 120 and the air deflector main body 110, and at the same time will not cause excessive air volume loss, improve the air supply efficiency, and ensure the air supply effect.

[0046] In some examples, as Figure 1 shown, the air deflector 100 further includes: a baffle 130, which is arranged in the middle of the edge of the first end.

[0047] It can be understood that the baffle 130 can be arranged in the middle of the first end edge of the air deflector main body 110, and both the baffle 130 and the airfoil plate 120 are arranged on the front surface of the air deflector main body 110. With such an arrangement, when the airflow accelerated by the airfoil plate 120 passes through the baffle 130, the flow direction of the airflow will be changed by the baffle 130, causing the airflow to flow further away from below the ceiling unit 200. Specifically, when the air deflector 100 is in normal operation, the air volume of the airflow on the front surface of the air deflector main body 110 is greater than that of the airflow on the back surface of the air deflector main body 110. Under the action of the Coanda effect, the airflow on the back surface of the air deflector main body 110 is drawn and blown out by the airflow on the front surface of the air deflector main body 110, so that the airflow under the action of the airfoil plate 120 and the baffle 130 flows further away from below the ceiling unit 200.

[0048] It should be noted that the length dimension of the baffle 130 is smaller than the length dimension of the air deflector main body 110, that is, there is a gap between the two ends of the baffle 130 and the air deflector main body 110. Part of the airflow will be sent to a farther distance under the action of the airfoil plate 120 and the baffle 130. Another part of the airflow will be blown out from the air outlet 240 through the gap to flow to the area below the ceiling unit 200, so that the airflow acts on the indoor environment more evenly and ensures the temperature adjustment effect of the ceiling unit 200.

[0049] In some examples, such as Figure 1 and Figure 5 as shown, the maximum distance dimension between the above-mentioned baffle 130 and the above-mentioned air deflector main body 110 is greater than or equal to the maximum distance dimension between the above-mentioned airfoil plate 120 and the above-mentioned air deflector main body 110.

[0050] It can be understood that the maximum distance dimension between the baffle 130 and the air deflector main body 110 should be greater than or equal to the maximum distance dimension between the airfoil plate 120 and the air deflector main body 110, so that the airflow on the front surface of the air deflector main body 110 after being accelerated by the airfoil plate 120 can be completely acted on by the baffle 130, ensuring the effect of changing the air supply direction, and due to the Coanda effect, the airflow on the back surface of the air deflector main body 110 changes its flow direction to direct the airflow to a farther distance and improve the air supply distance.

[0051] In some examples, the distance dimension between the above-mentioned airfoil plate 120 and the above-mentioned baffle 130 is greater than or equal to 10 mm.

[0052] It can be understood that if the distance dimension between the airfoil plate 120 and the baffle plate 130 is too small, it will cause the air flow acting on the airfoil plate 120 to collide with the air flow whose direction is changed by the baffle plate 130 during the acceleration process, forming a mixed flow, which will affect the acceleration effect of the airfoil plate 120 on the air flow and the effect of the baffle plate 130 on changing the air flow direction, thus affecting the air supply distance and the uniformity of the indoor environment temperature field. Therefore, the distance dimension between the airfoil plate 120 and the baffle plate 130 should be set to be greater than or equal to 10 mm. After ensuring that the airfoil plate 120 fully accelerates the air flow and the air flow flows stably for a certain distance, the air flow direction is changed by the baffle plate 130 to avoid chaotic air flow and improve stability.

[0053] In some examples, the length dimension of the above airfoil plate 120 accounts for 60% to 70% of the length dimension of the above air deflector main body 110; and / or the length dimension of the above baffle plate 130 accounts for 60% to 70% of the length dimension of the above air deflector main body 110.

[0054] It can be understood that, as Figure 1 shown, the extending direction of the air deflector main body 110 is the length direction. If the length dimension of the airfoil plate 120 is small, it will cause less air flow acting on the airfoil plate 120, and the acceleration effect on the air flow is poor, resulting in a shorter air supply distance of the ceiling unit 200. If the length dimension of the airfoil plate 120 is large, it will cause less air flow flowing out from the gaps between the two ends of the airfoil plate 120 and the air deflector main body 110, resulting in less air flow below the ceiling unit 200 and uneven air supply, affecting the uniformity of the temperature field of the indoor environment. Therefore, the length dimension of the airfoil plate 120 is set to account for 60% to 70% of the length dimension of the air deflector main body 110.

[0055] It can be understood that if the length dimension of the baffle plate 130 is small, it will cause less air flow acting on the baffle plate 130, and the effect of changing the air flow direction to blow farther is poor. At the same time, the Coanda effect is poor, and the effect of adjusting the air flow on the back of the air deflector main body 110 to follow the air flow on the front of the air deflector main body 110 is poor, resulting in a shorter air supply distance of the ceiling unit 200. If the length dimension of the baffle plate 130 is large, it will cause less air flow flowing out from the gaps between the two ends of the baffle plate 130 and the air deflector main body 110, and the air supply is uneven, affecting the uniformity of the temperature field of the indoor environment. Therefore, the length dimension of the baffle plate 130 is set to account for 60% to 70% of the length dimension of the air deflector main body 110.

[0056] It can be understood that the length dimension of the airfoil plate 120 is substantially the same as that of the baffle plate 130, so as to ensure that the air flow accelerated by the airfoil plate 120 can be completely deflected by the baffle plate 130 and blown to a farther distance. At the same time, sufficient air flow flows out through the gaps between the airfoil plate 120 and both ends of the air guide plate main body 110 and through the gaps between the baffle plate 130 and both ends of the air guide plate main body 110, and blows to a relatively short distance below the ceiling unit 200, so as to increase the coverage area of the air flow and improve the uniformity of the temperature field in the indoor environment.

[0057] In some examples, the above-mentioned airfoil plate 120 and the above-mentioned air guide plate main body 110 are of an integrated structure; and / or the above-mentioned baffle plate 130 and the above-mentioned air guide plate main body 110 are of an integrated structure.

[0058] It can be understood that the airfoil plate 120 and the air guide plate main body 110 can be made by an integral injection molding process, so as to improve the connection strength between the airfoil plate 120 and the air guide plate main body 110, improve the overall structural strength and stiffness of the air guide plate 100, and reduce the deformation amount of the air guide plate 100. The baffle plate 130 can also be made with the air guide plate main body 110 by an integral injection molding process, so as to improve the connection strength between the baffle plate 130 and the air guide plate main body 110, improve the overall structural strength and stiffness of the air guide plate 100, and reduce the deformation amount of the air guide plate 100.

[0059] In some examples, such as Figure 1 and Figure 4 shown, the above-mentioned air guide plate 100 further includes: a rotating shaft 140, which is arranged on the side of the above-mentioned air guide plate main body 110.

[0060] It can be understood that the air guide plate 100 can also be provided with a rotating shaft 140. Specifically, the rotating shaft 140 can be arranged on the side of the air guide plate main body 110, and the rotating shaft 140 is rotatably connected to the panel 220 of the ceiling unit 200 through a shaft sleeve, so as to drive the air guide plate main body 110 to rotate relative to the panel 220 through the rotating shaft 140. At the same time, the ceiling unit 200 can be provided with a stepping motor 270, and the power output shaft of the stepping motor 270 can be connected to the side of the air guide plate main body 110 through an anti-electricity shaft to provide power for the rotation of the air guide plate main body 110.

[0061] Such as Figure 5 and Figure 6 shown, according to the second aspect of the embodiments of the present application, a ceiling unit 200 is proposed, including: the air guide plate 100 described in any one of the above technical solutions; a housing 210; a panel 220, which is connected to the above-mentioned housing 210, an air inlet is provided in the middle of the above-mentioned panel 220, and air outlets 240 are provided on the periphery of the above-mentioned air inlet, and the above-mentioned air guide plate 100 is rotatably arranged at the above-mentioned air outlets 240; an evaporator 250, which is arranged in the above-mentioned housing 210;

[0062] The centrifugal air impeller 260 is disposed inside the above-mentioned housing 210 and is located between the above-mentioned evaporator 250 and the above-mentioned panel 220.

[0063] It can be understood that since the ceiling air conditioner 200 is provided with the above-mentioned air deflector 100, it has all the beneficial effects of the air deflector 100, which will not be elaborated here. The ceiling air conditioner 200 is also provided with a housing 210, a panel 220, an evaporator 250, and a centrifugal air impeller 260. Among them, the panel 220 can be connected to the housing 210, and a receiving space is formed inside the housing 210 to accommodate components. Specifically, the evaporator 250 and the fixing structure of the evaporator 250 can be disposed inside the housing 210. The centrifugal air impeller 260 and the motor and fixing structure of the centrifugal air volume can be disposed inside the housing 210, and the centrifugal air volume is located between the evaporator 250 and the panel 220. An air inlet can be provided in the middle of the panel 220, and a plurality of air outlets 240 can be provided on the periphery of the air inlet to blow air in multiple directions simultaneously, improving the air outlet uniformity. A wind guiding ring 280 can also be provided between the centrifugal air impeller 260 and the panel 220. With such a setting, after the ceiling air conditioner 200 is started, the centrifugal air impeller 260 operates to suck the air in the indoor environment from the air inlet, exchange heat with the evaporator 250, and then, after the action of the centrifugal air impeller 260, the air flow direction is guided by the wind guiding ring 280 to flow to the air deflector 100, and is blown out through the air outlets 240 under the action of the air deflector 100 to adjust the indoor environment temperature. An air inlet grille 230 can be provided at the air inlet to block larger foreign objects from entering the air inlet, improving the protection of the components inside the housing 210.
