Air deflector and air conditioner

Abstract

This application relates to the field of air conditioner technology and discloses an air guide plate and an air conditioner. The air guide plate provided in this application includes an air guide plate body with an air guiding surface. The air guiding surface includes an inlet section, a flow stabilizing section, and an outlet section connected in sequence. The inlet section, flow stabilizing section, and outlet section are all curved surfaces. The radius of curvature of the inlet section is smaller than that of the flow stabilizing section, and the radius of curvature of the flow stabilizing section is smaller than that of the outlet section. This air guide plate, by setting an air guiding surface and dividing it into an inlet section, a flow stabilizing section, and an outlet section, ensures that the radius of curvature of the inlet section is smaller than that of the flow stabilizing section, and the radius of curvature of the flow stabilizing section is smaller than that of the outlet section. This allows the airflow to adhere to the surface of the inlet section after flowing through the air guiding surface. Furthermore, the gradually increasing radius of curvature allows the decelerated airflow to further conform to the flow stabilizing section and the outlet section, reducing airflow separation, thereby reducing wind resistance, increasing the airflow delivery distance, and solving the problem of short airflow delivery distance.

Description

Technical Field

[0001] This application belongs to the field of air conditioner technology, and particularly relates to air guide vanes and air conditioners. Background Technology

[0002] Air conditioner vents typically have deflectors to adjust the airflow angle. As airflow passes over the deflector, it collides with the deflector, causing a change in airflow direction. However, the airflow loses significant kinetic energy when colliding with the deflector, resulting in a short airflow distance.

[0003] Therefore, improvements to existing technologies are necessary.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0023] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0024] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides an air guide plate and an air conditioner to solve the problem of short airflow delivery distance. The following description will be provided in conjunction with the accompanying drawings.

[0027] Please see Figure 1 and Figure 2 This application provides an air guide plate, including an air guide plate body 1. The air guide plate body 1 has an air guiding surface 3. The air guiding surface 3 includes an air inlet section 31, a flow stabilizing section 32, and an air outlet section 33 connected in sequence. The air inlet section 31, the flow stabilizing section 32, and the air outlet section 33 are all curved surfaces. The radius of curvature of the air inlet section 31 is smaller than the radius of curvature of the flow stabilizing section 32, and the radius of curvature of the flow stabilizing section 32 is smaller than the radius of curvature of the air outlet section 33.

[0028] By setting an air guide surface 3 and dividing it into an inlet section 31, a flow stabilizing section 32, and an outlet section 33, the radius of curvature of the inlet section 31 is smaller than that of the flow stabilizing section 32, and the radius of curvature of the flow stabilizing section 32 is smaller than that of the outlet section 33. This allows the airflow to adhere to the surface of the inlet section 31 after flowing through the air guide surface. Furthermore, the gradually increasing radius of curvature allows the decelerated airflow to further conform to the flow stabilizing section 32 and the outlet section 33, reducing airflow separation, thereby reducing wind resistance, increasing the airflow delivery distance, and solving the problem of short airflow delivery distance.

[0029] Please see Figure 1 and Figure 2 In this embodiment, the air guide plate includes an air guide plate body 1 and two rotating shafts 2. Both rotating shafts 2 are located on the air guide surface 3, and are respectively located at both ends of the length direction of the air guide plate body 1. The air guide plate body 1 is biomimetic airfoil-shaped, making the windward side of the air guide plate body 1 curved. In addition, multiple serrations 11 are provided on the windward side of the air guide plate body 1. The multiple serrations 11 are arranged sequentially and spaced apart along the length direction of the windward side, so that the windward side of the air guide plate body 1 forms a serration structure similar to an owl feather, which can disperse the tail vortex and reduce mid-to-high frequency noise.

[0030] Please see Figure 1 and Figure 2 The radius of curvature of the air intake section 31 is R1, where 10mm ≤ R1 ≤ 20mm. In this embodiment, the value of R1 is 15mm. In some embodiments of this application, the value of R1 is any one of 10mm, 11mm, 12mm, 13mm, 14mm, 16mm, 17mm, 18mm, 19mm, and 20mm. By ensuring that 10mm ≤ R1 ≤ 20mm, not only can the airflow quickly adhere to the surface of the air intake section 31 after entering it, reducing kinetic energy loss caused by direct collision between the airflow and the air guide plate body 1, but the airflow can also be accelerated, thereby increasing the airflow delivery distance.

[0031] Please see Figure 1 and Figure 2 The radius of curvature of the flow stabilizing section 32 is R2, where 25mm ≤ R2 ≤ 55mm. In this embodiment, the radius of curvature R2 of the flow stabilizing section 32 gradually increases along the direction from the intake section 31 to the outlet section 33. By ensuring that 25mm ≤ R2 ≤ 55mm and gradually increasing the radius of curvature of the flow stabilizing section 32, the airflow flowing in from the intake section 31 can enter the flow stabilizing section 32 and remain attached to it, reducing airflow separation from the flow stabilizing section 32, guiding the airflow to flow stably, and thus reducing wind resistance.

[0032] Please see Figure 1 and Figure 2 The radius of curvature of the outlet section 33 is R3, where 60mm ≤ R3 ≤ 100mm. In this embodiment, the value of R3 is 80mm. In some embodiments of this application, the value of R3 is any one of 60mm, 65mm, 70mm, 75mm, 85mm, 90mm, 95mm, and 100mm. By ensuring that 60mm ≤ R3 ≤ 100mm, the airflow flowing in from the stabilizing section 32 can enter the outlet section 33 and remain attached to it, reducing airflow separation from the stabilizing section 32 and thus reducing wind resistance.

[0033] Please see Figure 1 and Figure 2 Furthermore, a diffuser surface 4 is provided on the air guide plate body 1, which connects the air outlet section 33 and the leeward end of the air guide plate body 1. The angle between the diffuser surface 4 and the tangent at the end of the air outlet section 33 away from the air inlet section 31 is b, where 5°≤b≤10°. In this embodiment, the value of b is 8°. In some embodiments of this application, the value of b is any one of 5°, 6°, 7°, 9°, and 10°. By ensuring that 5°≤b≤10°, the formation of turbulence can be suppressed, and the noise caused by the formation of vortices on the leeward side of the air guide plate after the airflow exits the air guide plate can be reduced.

[0034] Please see Figure 1 and Figure 2 An air guide plate body 1 is provided with an air-guiding surface 5, which is located on the side of the air guide plate body 1 away from the air guide surface 3. Multiple guide fins 51 are provided on the air guide surface 5, and the density of the guide fins 51 gradually increases along the direction from the air inlet section 31 to the air outlet section 33. Each guide fin 51 includes a guide slope 52 and a support surface 53 connected in sequence. The end of the guide slope 52 away from the support surface 53 is connected to the air guide surface 5, and the end of the support surface 53 away from the guide slope 52 is connected to the air guide surface 5.

[0035] Please see Figure 1 and Figure 3 The angle between the tangent at the connection point between the guide slope 52 and the air intake surface 5 and the guide slope 52 is α, where 20°≤a≤30°. In this embodiment, the value of α is 25°. In some embodiments of this application, the value of α is any one of 20°, 21°, 22°, 23°, 24°, 26°, 27°, 28°, 29°, and 30°. By ensuring that 20°≤a≤30°, the thickness of the viscous sublayer of the airflow can be increased, which helps to reduce the average velocity gradient on the air intake surface 5. Furthermore, the guide fins 51 hinder the occurrence of instantaneous lateral flow caused by turbulent motion, reducing the overall turbulent change within the airflow boundary layer, thereby reducing the frictional resistance of the air intake surface 5.

[0036] Please see Figure 1 and Figure 3 In addition, an anti-condensation structure is provided on the air guide surface 3. The anti-condensation structure includes a heat insulation layer 61, a heating layer 62, and a hydrophobic layer 63 arranged sequentially. The side of the heat insulation layer 61 away from the heating layer 62 is attached to the air guide surface 3. The hydrophobic layer 63 can reduce water droplets adhering to the surface of the air guide plate body 1. The heating layer 62 is used to heat the air guide plate body 1, so that the temperature of the air guide plate body 1 can be higher than the dew point temperature of the ambient air. The setting of the heat insulation layer 61 helps to reduce the heat loss of the air guide plate body 1, so that the temperature of the air guide plate body 1 can be maintained at a state higher than the dew point temperature of the ambient air.

[0037] This application also provides an air conditioner that includes the air guide plate described above. Since the air conditioner has the aforementioned air guide plate, it possesses at least some or all of the beneficial effects of the aforementioned air guide plate, which will not be elaborated upon here.
