DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the application more clear and obvious, the embodiments of the application will be described in detail below with reference to the drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily without conflict. Those skilled in the art can understand that the heating assembly of the application is particularly suitable for a warmer, especially an electric heater.

[0032] As shown in Figures 1-4 , the heating assembly of the application comprises a heating body 1, an air duct support 2 and a fan 3, wherein the heating body 1, the air duct support 2 and the fan 3 are independent module structures, which can be manufactured and installed independently to reduce the cost. The heating assembly of the application can improve the air speed of the heating assembly by designing the air duct support between the heating body and the fan to realize installation.

[0033] The heating body 1 is arranged on one side of the air outlet surface 212 of the air duct support 2, and the fan 3 is arranged on one side of the air inlet surface 210 of the air duct support 2. The air duct support 2 is provided with a wind guide structure 21 for adjusting the air speed in the air duct. Specifically, the wind guide structure 21 includes a plurality of wind guide blades 24, and the plurality of wind guide blades 24 are respectively fixedly arranged on the inner wall of the air duct support 2 to form a wind guide structure, thereby increasing the air speed. Further, the heating body is a PTC heating body. Specifically, the fan 3 blows air into the air duct of the air duct support 2, the air is accelerated by the wind guide structure 21, and then is blown out along the air outlet surface 212 of the air duct support 2, and then enters the PTC heating body through the air inlet end surface 11 of the PTC heating body, and finally is blown out from the air outlet side of the PTC heating body. The heating assembly provided in the application is provided with an air duct support between the heating body and the fan, and a wind guide structure is arranged in the air duct support, so that the air speed of the heating assembly is larger, and the problem of small air speed of the heating assembly can be solved.

[0034] As shown in Figure 8 , Figure 10 , Figure 11 indicated, in some embodiments, the air inlet end surface 11 of the heating body 1 is not parallel to the edge 22 of the air outlet side of the wind guide blade 24. This design mainly considers that the air speed from the air duct is not perpendicular to the air inlet end surface 11, but flows out along the direction of the wind guide blade, and the air direction has a certain angle.

[0035] As shown in Figure 8 , Figure 10 , Figure 11 indicated, specifically, the air in the air duct is accelerated by the wind guide blade and can be blown out at a specific angle, so the air inlet end surface 11 of the heating body 1 and the edge 22 of the air outlet side of the wind guide blade 24 are designed to have a corresponding angle; specifically, the included angle a between the air inlet end surface 11 of the heating body 1 and the edge 22 is 1° to 15°, and the included angle a is preferably 2°, 4°, 6°, 9° or 12°. The heating assembly provided in the application can increase the air speed of the heating assembly by designing a specific included angle between the air duct support and the heating body.

[0036] As shown in Figure 5 and Figure 6As shown in the drawings, in some embodiments, the air guide structure 21 in the air duct support 2 further comprises a support ring 23 arranged at the center of the air duct support 2, and a plurality of air guide blades 24 are uniformly arranged on the circumference of the outer wall of the support ring 23. Specifically, one end of each of the plurality of air guide blades 24 is uniformly fixed on the circumference of the outer wall of the support ring 23, i.e., one end of each of the plurality of air guide blades 24 is uniformly fixed on the circumference of the outer wall of the support ring 23. The other end of each of the plurality of air guide blades 24 is uniformly fixed on the circumference of the inner wall of the air duct support 2, i.e., the other end of each of the plurality of air guide blades 24 is uniformly fixed on the circumference of the inner wall of the air duct support 2, thereby forming the air guide structure.

[0037] As shown in the drawings, Figure 9 In some embodiments, in order to improve the air outlet effect of the air duct support 2 and improve the air outlet speed, the air guide blades are designed with a twist angle. Since the air guide blades 24 are twisted to form a guide angle in an arc structure, there is an included angle b between the tangent line B at the connection point of the air guide blades 24 and the outer wall of the support ring 23 and the tangent line at the connection point of the support ring 23. The included angle b is 45° to 90°, and the included angle b is preferably 65°, 73°, 75°, 77° or 83°. Further, the included angle c between the tangent line A at one end of the air guide blade 24 connected to the inner wall of the air duct support 2 and the inner wall of the air duct support 2 is 90° to 130°, and the included angle c is preferably 102°, 107°, 113°, 116°, 120°, 123° or 127°. In the present application, the included angle a and the twist angle of the air guide blade, i.e., the included angle b and the included angle c, cooperate with each other to improve the air speed of the heating assembly. See Table 1 below for details.

[0040] In the present application, an air duct support is designed between the heating body and the fan, and the specific structure of the air duct support is designed to effectively improve the air outlet speed of the heating assembly. See Table 2 below for details:

[0043] As shown in the drawings, Figures 1 to 6As shown in the drawings, in some embodiments, the fan 3 includes a motor, which is arranged at the center of the fan. Further, the support ring 23 is provided with a blocking cavity 211, which is located at the center of the air inlet face 210; and the air inlet face 210 is provided with a mounting structure for mounting and cooperating with the fan. Specifically, the fan 3 is connected with the mounting structure together, so that the motor is arranged at the blocking cavity position of the air inlet face 210, thereby forming a wind blocking face. The support ring 23 can support the guide vane, and by designing the blocking cavity, the weight of the material is reduced, and the motor can form a shielding structure, so that the wind in the air duct can be affected by the guide vane to accelerate and reduce the disturbance at the center of the air duct.

[0044] As shown in the drawings, Figures 1 to 6 In some embodiments, the mounting structure includes a blocking edge 27 and a buckle, which are respectively fixedly arranged on the periphery of the air inlet face 210. Further, the air outlet end face 31 of the fan 3 is arranged on the air inlet face 210; the outer side edge of the fan 3 abuts on the blocking edge 27, and the buckle is buckled with the fan 3 together, so that the fan 3 is mounted on the air inlet face 210 as a whole. Specifically, the air inlet face 210 is a quadrilateral structure, the blocking edge 27 is an L-shaped structure, and two blocking edges 27 are respectively arranged on the diagonal opposite corners of the air inlet face 210. The buckle includes a positioning buckle 28 and a positioning wall 29, two positioning buckles 28 are respectively arranged on the other diagonal opposite corners of the air inlet face 210, and the end of the positioning wall 29 forms a clamping jaw. In the above scheme, by arranging the blocking edge 27 and the positioning buckle 28 on the four corners of the air inlet face 210, the fan 3 can be mounted in the four corners of the air inlet face 210, and the positioning buckle 28 is buckled on the side wall of the fan, and the clamping jaw of the positioning wall 29 is buckled on the air inlet side of the fan, thereby achieving the fixed connection.

[0045] As shown in the drawings, Figure 7 In some embodiments, the thickness between the air outlet face 212 and the air inlet face 210 of the fan bracket 2 is 5mm to 25mm, preferably 6mm, 10mm, 12mm, 18mm and 20mm. It should be emphasized that the thickness of the air outlet face and the air inlet face 210 designed in the application is based on the overall structure of the air duct bracket, especially the guide structure in the air duct bracket. If the thickness of the air outlet face and the air inlet face 210 is insufficient or too thick, the acceleration effect of the guide vane will be reduced. The heating assembly proposed in the application can effectively improve the wind speed of the heating assembly by designing the thickness of the air duct bracket.

[0046] As shown in the drawings, Figures 5 to 6As shown, in some embodiments, the number of the air guide blades 24 includes 5 to 20, preferably 5, 6, 8, 10, 13 or 18, see Table 3 below, which can be concluded that the air speed is higher than the air speed of 2.2 m / s of the existing heating assembly. It should be noted that the number of the air guide blades 24 designed in the present application is based on the overall structure of the air duct support, especially the air guide structure in the air duct support. Too few or too many air guide blades 24 will reduce the acceleration effect of the air guide blades.
