[0067] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0068] At present, most of the existing fan lights are axial flow large blade fan type. Fan lights based on axial flow blades are therefore limited in the installation position of the light source. Usually, only a light source is installed at the bottom of the axial flow blade. This type of fan light has a relatively high overall height and occupies a large space when in use. The fan light in the embodiment of the present invention is bladeless, and the air duct is integrated into the interior of the fan module. By setting the first light-emitting component of the fan light at the bottom of the fan module and setting the light-emitting surface of the first light-emitting component to be higher than the air outlet surface of the air outlet, the overall height of the fan can be effectively reduced, and at the same time, the air outlet and lighting effects of the fan light will not be affected.

[0069] The following is combined with Figure 1-11 The technical solution of this embodiment is elaborated in detail. In the absence of conflict, the following implementation methods and embodiments can be combined with each other.

[0070] Example

[0071] like Figure 1-Figure 11 As shown, this embodiment provides a fan lamp, including:

[0072] The fan module 1 comprises a top portion close to the installation position when installed, a bottom portion opposite to the top portion and away from the top portion when installed, and a peripheral portion between the top portion and the bottom portion, an air inlet 12 is provided on the peripheral portion, an air outlet 11 is provided on the bottom portion, and an air duct connecting the air inlet 12 and the air outlet 11 is provided inside the fan module 1;

[0073] The impeller 64 is disposed in the air duct, and is used to introduce the airflow from the air inlet of the fan module 1 into the air duct and discharge the airflow introduced into the air duct from the air outlet 11 of the fan module 1;

[0074] The first light-emitting component 2 is arranged at the bottom of the fan module 1, wherein the light-emitting surface of the first light-emitting component 2 is spaced apart from the air outlet surface of the air outlet 11 and the light-emitting surface of the first light-emitting component 2 is close to the installation position of the fan module relative to the air outlet surface of the air outlet 11.

[0075] like Figure 4As shown, the fan light in the embodiment of the present invention is of bladeless type, and the air duct is integrated into the interior of the fan module 1. By setting the first light-emitting component 2 of the fan light at the bottom of the fan module 1 and setting the light-emitting surface of the first light-emitting component 2 to be higher than the air outlet surface of the air outlet 11, the overall height of the fan can be effectively reduced without affecting the air outlet and lighting effects of the fan light.

[0076] It should be noted that the light-emitting surface, air outlet surface and installation surface mentioned in the embodiments of the present invention are not required to be completely flat surfaces, as long as they are similar to planes. For example, light-emitting surfaces and air outlet surfaces with slightly curved surfaces can be identified as the light-emitting surfaces and air outlet surfaces mentioned in the embodiments of the present invention.

[0077] It should also be noted that, when a component is set at the "bottom of the fan module 1" as mentioned in the embodiment of the present invention {for example, a first light-emitting component and an air outlet are set at the bottom}, the "bottom" here does not mean that this component is completely set at the bottom of the fan module, it only represents a relative position relationship with the top of the fan module.

[0078] Specifically, the first light-emitting component 2 is arranged around the periphery of the air outlet 11. In the embodiment of the present invention, by arranging the first light-emitting component 2 around the periphery of the air outlet 11, the fan module 1 can be prevented from being blocked by the first light-emitting component 2 in the air outlet direction, thereby ensuring the air outlet effect of the air outlet 11.

[0079] More specifically, Figure 1-Figure 3 As shown, the first light-emitting component 2 is disposed around the edge of the bottom of the fan module 1. The projection center of the downward projection of the fan module 1 coincides with the projection center of the downward projection of the first light-emitting component 2.

[0080] In the embodiment of the present invention, by setting the first light-emitting component 2 at the bottom edge of the fan module 1, the lighting area can be maximized. At the same time, the projection center of the downward projection of the fan module 1 also coincides with the projection center of the downward projection of the first light-emitting component 2.

[0124] In any of the above embodiments, a convex rib 611 convex toward the crossflow impeller 64 is provided on the inner wall surface of the crossflow air duct, and there is one convex rib 611 extending along the lateral direction of the air duct housing 1; the lateral direction of the air duct housing 61 is a direction parallel to the axis of the impeller 64;

[0125] The rib 611 has a curved surface protruding from the inner wall surface of the cross-flow air duct;

[0126] The inner wall surface of the cross-flow air duct has a closest position to the impeller 64 , and the rib 611 is disposed at or near the closest position.

[0127] In the embodiment of the present invention, a convex rib 611 is provided on the inner wall surface of the cross-flow duct to increase the outlet wind pressure and accelerate the airflow. At the same time, the convex rib 611 is provided in a curved shape to avoid generating large aerodynamic noise when accelerating the airflow.

[0128] It should be noted that the convex rib 611 in the embodiment of the present invention can only be set to one. If the number of the convex rib 611 is set to multiple, it will affect the flow rate. For example, when there are two or more convex ribs 611, the airflow will increase the wind resistance and friction when flowing through the convex rib 611, forming reverse refracted wind, thereby reducing the flow rate.

[0129] It should also be noted that the convex rib 611 in the embodiment of the present invention is preferably arranged in an arc shape, so that the airflow can accelerate the airflow velocity when passing through the convex rib without forming internal turbulence inside the air duct, thereby increasing the wind speed and wind pressure while not increasing the airflow noise. If the convex rib 611 is not arc-shaped, but is step-shaped or plane-shaped, internal turbulence will be formed inside the air duct, thereby reducing the wind speed and increasing the turbulent noise. It should be noted that the rib 611 in the embodiment of the present invention is an arc-shaped rib, which is not required to be a complete arc, as long as the surface of the convex rib 611 is relatively smooth. It should also be noted that the wind pressure increased by setting the convex rib 611 in the embodiment of the present invention refers to the wind pressure of the air duct at the air outlet 11, that is, the overall air supply pressure of the air duct when the air is supplied, and does not refer to the wind pressure at the position of the convex rib 611.

[0130] In the embodiment of the present invention, by setting the position of the rib 611 at the closest distance between the air duct and the impeller 64, the air flow backflow can be effectively increased, and the air flow can be quickly pressurized when passing through.

[0131] In any of the above embodiments, if Fig.10 As shown, the lateral direction of the rib 611 extends along the lateral direction of the air duct housing, and the lateral direction of the air duct housing is parallel to the axial direction of the impeller 64;

[0132] The transverse direction of the rib 611 is coplanar with the axial direction of the impeller.

[0133] The convex rib 611 in the embodiment of the present invention is extended in the transverse direction of the air duct housing, which can further improve the acceleration effect of the airflow when it flows through the position of the convex rib 611.

[0134] In any of the above embodiments, the convex rib 611 has a first curved surface as a windward surface and a second curved surface as a leeward surface in the air supply direction of the air duct housing 61, a third curved surface is smoothly transitioned between the first curved surface and the second curved surface, and the first curved surface and the second curved surface are symmetrically arranged on both sides of the third curved surface;

[0135] The first arc surface and the second arc surface are concave arc surfaces arranged relative to the impeller, and the third arc surface is a convex arc surface arranged relative to the impeller;

[0136] The inner wall surface of the air duct includes a first inner wall surface and a second inner wall surface located on both sides of the convex rib 611, the first inner wall surface of the air duct smoothly transitions with the first curved surface, and the second inner wall surface of the air duct smoothly transitions with the second curved surface.

[0137] In the embodiment of the present invention, the convex rib 611 is arranged between the first inner wall surface of the air duct and the second inner wall surface of the air duct, and the first inner wall surface of the air duct and the second inner wall surface of the air duct are smoothly transitioned by the convex rib having three arc surfaces, namely, the first arc surface, the second arc surface and the third arc surface, so that the convex rib 611 can be smoothly connected to the inner wall surface of the air duct, thereby further reducing the aerodynamic noise generated when the airflow flows in the air duct.

[0138] In any of the above embodiments, the protruding height of the rib 611 toward the impeller 64 is between 0.7 mm and 1 mm.

[0139] In the embodiment of the present invention, by setting the height of the rib 611 between 0.7 mm and 1 mm, the airflow outlet effect can be optimized. The "airflow outlet effect is optimized" in the embodiment of the present invention means finding a balance point between the airflow velocity and the airflow noise. At this time, the airflow velocity can be increased and the noise during the airflow flow can be reduced, thereby optimizing the air outlet effect.

[0140] In any of the above embodiments, if Fig.10 and Fig.11 As shown, the main air duct includes an air inlet section, a middle section and an air outlet section connected in sequence in the air supply direction;

[0141] The air inlet section is formed with an air inlet, the air outlet section is formed with an air outlet, and the impeller 64 is arranged on the middle section;

[0142] The air inlet section and the air outlet section both form straight inner wall surfaces of the air duct, the middle section forms a curved inner wall surface of the air duct, and the straight surface of the air inlet section, the curved surface of the middle section and the straight surface of the air outlet section form a smooth transition.

[0143] That is, the inner wall section of the air duct in the embodiment of the present invention transitions along the impeller curve arc, and is composed of three curved surfaces, namely, a horizontal straight surface, an arc curved surface, and a vertical straight surface. Fig.10 As shown in the figure, the three-segment surface smoothly transitions along the section of the impeller, which can effectively improve the smoothness of fluid flow.

[0144] In any of the above embodiments, the width of the air inlet 12 is greater than the diameter of the impeller 64;

[0145] The air inlet area of ​​the air inlet 12 is greater than the air outlet area of ​​the air outlet 11 .

[0146] The embodiment of the present invention can improve air inlet blockage, improve air outlet performance, and ensure smooth air inlet by setting the air inlet width of the air inlet 12 larger than the diameter of the impeller 64, thereby avoiding the formation of turbulence inside the air duct and reducing vibration noise and vibration frequency. By setting the air inlet area of ​​the air inlet to be larger than the air outlet area of ​​the air outlet, the air duct structure is more reasonable, and the air supply distance of the compressed air at the air outlet can be increased.

[0147] Preferably, the ratio of the width of the air inlet 12 to the diameter of the impeller 64 is 3:2. It should be noted that if the ratio exceeds 3 / 2, the air inlet is saturated and the extra air inlet area is of little significance. If the ratio is less than 3 / 2, the air inlet volume is insufficient and the wind speed is reduced.

[0148] Preferably, the air inlet area of ​​the air inlet 12 is three times the air outlet area of ​​the air outlet 11. In this case, the air supply duct structure is more reasonable and the air supply distance of the compressed air from the air outlet can be increased.

[0149] In any of the above embodiments, if Figure 3 As shown, an angle a is formed between the air inlet direction of the air inlet 12 and the air outlet direction of the air outlet 11;

[0150] The angle a is designed to be: 90°<a<110°.

[0151] That is, the air inlet 12 and the air outlet 11 in the embodiment of the present invention are at a certain angle, that is, the overall air inlet and air outlet angles of the air duct in the embodiment of the present invention are set between 90°-110°, and the air supply is smoother at this time. Preferably, when the overall air inlet and air outlet angles of the air duct are set between 90°-95°, the smoothness of the air supply reaches the optimum. At this time, the air supply capacity of the impeller 64 is enhanced, which effectively increases the air flow velocity and flow rate, makes the fluid smoother in the air duct space, and reduces air friction loss.

[0152] In any of the above embodiments, if Fig.10 As shown, the air duct is formed with a volute tongue structure 62 at the position where the cross-flow impeller is set, and the air inlet and the air outlet are set on both sides of the volute tongue structure 62. The volute tongue structure 62 has a volute tongue angle b in the range of 70°-90°.

[0153] In the embodiment of the present invention, by arranging the volute tongue structure 62 on both sides of the air inlet 12 and the air outlet 11, turbulence inside the air duct can be avoided and resonance noise can be reduced. By setting the angle of the volute tongue structure 62 between 70° and 90°, the air flow velocity can be effectively increased. Preferably, when the angle of the volute tongue structure 62 is 80°, the effect of increasing the air flow velocity is optimal.

[0154] In any of the above-mentioned embodiments, the air outlet 12 is constructed as a gradually expanding structure. Preferably, the outlet expansion angle of the air outlet 12 is set between 40° and 45°.

[0155] In the embodiment of the present invention, the air outlet 12 is configured to be gradually expanded and the expansion angle is set between 40° and 45°, so that the air supply distance and air supply volume can be effectively increased.

[0156] It is worth noting that if the expansion angle is set to be greater than 45°, the air supply distance will be affected, and if the expansion angle is set to be lower than 40°, the air supply volume will be lost; therefore, in the embodiment, setting the expansion angle of the air outlet 12 to 40°-45° is the best angle, and the air outlet 12 at this time can increase both the air supply distance and the air supply volume.

[0157] The fan lamp in the embodiment of the present invention adopts the above-mentioned air duct structure, which can effectively improve the product performance by more than 50% in air output compared with similar products on the market, and reduce the noise by more than 30% year-on-year, thereby improving the product experience.
