[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0037] The disclosure below provides many different embodiments or examples to implement the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0038] In order to solve the technical problem in the prior art that air conditioning wind of a vehicle air conditioner cannot be effectively introduced into the passenger compartment, the present application provides an air guide device 1 for a vehicle air conditioner, and the air guide device 1 includes a main body.
[0039] Specifically, if Figure 1-Figure 7 As shown, the main body has an air inlet 10 and an air outlet 20, and an air guide channel 30 connected to the air inlet 10 and the air outlet 20 is defined in the main body. The main body is suitable for being connected to the outside of the body of the vehicle air conditioner (not shown in the figure), and the air inlet 10 is connected to the air outlet of the body, and the axial direction of the air inlet 10 intersects with the axial direction of the air outlet 20. The air guide channel 30 includes a first air guide surface 31, and the first air guide surface 31 is used to guide the airflow entering the air guide channel 30 from the air inlet 10 to the air outlet 20.
[0040] When the vehicle's onboard air conditioner is a back-mounted split air conditioner, the air conditioner is installed on the rear side of the passenger compartment. The passenger compartment has ventilation holes, and the air flows into the passenger compartment through the ventilation holes. The ventilation holes are generally set on the ceiling of the top floor of the passenger compartment. Therefore, it is necessary to guide the air conditioning wind on the rear side of the passenger compartment to the ventilation holes on the ceiling of the passenger compartment, and then enter the passenger compartment through the ventilation holes. In the prior art, a hose is generally set between the air outlet and the ventilation hole of the vehicle-mounted air conditioner. However, the hose is easy to deform, and the connection with the air outlet of the vehicle-mounted air conditioner cannot be stably connected, resulting in the air conditioning wind flowing out of the air outlet cannot be effectively introduced into the passenger compartment, affecting the wind speed and air volume flowing into the passenger compartment, affecting the user experience.
[0041] like Figure 1 and Figure 5 As shown, the air guide channel 30 has a first air guide surface 31. By providing the first air guide surface 31, the air flow direction can be changed easily. Figure 1-Figure 7As shown, the main body can be installed on the machine body, and the air inlet 10 of the main body is arranged opposite to the air outlet of the machine body, so that the wind can be effectively introduced into the air guide channel 30. The vehicle air conditioner may include a hose such as a bellows (not shown in the figure), and the air outlet 20 of the main body can be connected to the hose, and the air flow flows to the passenger compartment through the hose. In order to facilitate the conversion of the airflow direction, the axial direction A of the air inlet 10 is set to intersect with the axial direction B of the air outlet 20, which can facilitate the change of the flow direction of the airflow. For example, Figure 5 As shown, after the air guide device 1 is installed to the body of the vehicle air conditioner, the air inlet 10 can be located on the rear side of the body, and the axial direction of the air inlet 10 extends along the front and rear direction of the vehicle. The air outlet 20 can be located on the front side of the body, and the axial direction of the air outlet 20 is directed obliquely upward and extends forward, so as to guide the airflow forward and toward the upper end of the passenger compartment.
[0042] Therefore, by setting the first wind guide surface 31, a guide effect can be achieved, and by making the axial direction of the air inlet 10 intersect with the axial direction of the air outlet 20, the flow direction of the airflow can be easily changed to increase the wind speed and air volume supplied to the passenger compartment, thereby improving the user experience.
[0043] In some embodiments, Figure 1 , Figure 4 as well as Figure 5 As shown, the first air guide surface 31 includes a first plane section 311 and a first curved section 312. One end of the first plane section 311 defines a portion of the boundary of the air inlet 10. The first plane section 311 is parallel to the axial direction A of the air inlet 10. The first curved section 312 is connected to the other end of the first plane section 311, that is, the first plane section 311 and the first curved section 312 are sequentially connected along the gas flow direction. The first curved section 312 protrudes in a direction away from the central axis of the air inlet 10, and the first plane section 311 and the first curved section 312 have a smooth transition.
[0044] Among them, it can be understood that the "curved surface" in the embodiment of the present application can be a surface formed by an arc surface, an elliptical surface or a combination of the two, which is not limited here. The specific setting method can be specifically set according to actual needs to ensure the diversion effect.
[0045] Thus, by providing the first plane section 311, the airflow can be smoothly introduced into the air guide channel 30, and by providing the first curved section 312, the streamlined design of the air guide channel 30 can be realized, so as to reduce air resistance, ensure the wind speed and air volume flowing into the passenger compartment, and improve the user experience. At the same time, the smooth transition between the first plane section 311 and the first curved section 312 can prevent the airflow from escaping from the first air guide surface 31, and can make the airflow change its flow direction smoothly, so as to further improve the air guide effect of the first air guide surface 31.
[0046] In some embodiments, Figure 2 , Figure 3 as well as Figure 6 As shown, the air guide channel 30 further includes a second air guide surface 32, which is connected to the first air guide surface 31 along the circumferential direction of the air guide channel 30, and includes a second plane segment 321 and a second curved segment 322, one end of the second plane segment 321 defines a portion of the boundary of the air inlet 10, the second plane segment 321 is parallel to the axial direction of the air inlet 10, and the second curved segment 322 is connected to the other end of the second plane segment 321. That is, the second plane segment 321 and the second curved segment 322 are sequentially connected along the gas flow direction.
[0047] Thus, by providing the second plane section 321, it is convenient for the airflow to smoothly enter the air guide channel 30, and by providing the second curved section 322, a streamlined design of the air guide channel 30 can be achieved, so as to reduce air resistance, ensure the wind speed and air volume of the airflow flowing into the passenger compartment, and improve user experience. At the same time, the second air guide surface 32 can cooperate with the first air guide surface 31 to further improve the smoothness of the airflow in the air guide channel 30, and ensure the wind speed and air volume of the airflow flowing into the passenger compartment.
[0048] In some embodiments, Figure 2 As shown, the second plane section 321 is connected to the second curved section 322 through a transition section 323 so that the second plane section 321 and the second curved section 322 are smoothly transitioned and connected. The transition section 323 protrudes in a direction away from the central axis of the air inlet 10, and the second curved section 322 protrudes in a direction toward the central axis of the air inlet 10.
[0049] In this way, the air flow guiding effect can be further improved, because the second curved section 322 and the transition section 323 are both curved surfaces with a smaller protrusion and a gentler curvature, which can further prevent the airflow from escaping from the second air guide surface 32, so as to increase the wind speed and air volume of the airflow flowing into the passenger compartment.
[0050] For example, the length of the first curved segment 312 is greater than the length of the first plane segment 311, and the length of the second curved segment 322 can be greater than the length of the second plane segment 321, so as to ensure the contact area between the airflow and the wind guide surface and improve the effect of changing the flow direction of the airflow and the guide stability.
[0051] In some embodiments, Figure 1 and Figure 4As shown, the air guide channel 30 further includes: a third air guide surface 33, the third air guide surface 33, the second air guide surface 32 and the first air guide surface 31 are sequentially connected along the circumferential direction of the air guide channel 30, one end of the third air guide surface 33 defines a part of the boundary of the air inlet and outlet 10, the other end of the third air guide surface 33 is connected to the first air guide surface 31, and the air outlet 20 is formed on the third air guide surface 33. Thus, by providing a plurality of air guide surfaces, it is possible to guide the airflow in multiple directions, so as to effectively guide the airflow flowing in from the air inlet 10 to the air outlet 20.
[0052] For example, in Figure 1 and Figure 4 In the example, the third air-guiding surface 33 may include a third plane segment 331 and a fourth plane segment 332 connected along the gas flow direction, the air outlet 20 is formed in the fourth plane segment 332, one end of the third plane segment 331 defines a portion of the boundary of the air inlet and outlet 10, which can facilitate the airflow to smoothly enter the air-guiding channel 30, the other end of the third plane segment 331 is connected to one end of the fourth plane segment 332, the other end of the fourth plane segment 332 is connected to the first air-guiding surface 31, and both ends of the fourth plane segment 332 are smoothly transitioned to ensure the smoothness of the airflow. Of course, in other embodiments, the third air-guiding surface 33 may include a third plane segment 331 and a curved surface segment (not shown) connected in the gas flow direction, and the air outlet 20 is formed in the curved surface segment, which is not limited here.
[0053] Reference Figure 1-Figure 6 The air guide channel 30 may further include a fourth air guide surface 34, the first air guide surface 31, the second air guide surface 32, the third air guide surface 33 and the fourth air guide surface 34 are sequentially connected along the circumferential direction of the air guide channel 30 to jointly construct the air guide channel 30, and the connection between the first to fourth air guide surfaces 34 may be smoothly transitioned and connected, the fourth air guide surface 34 may be constructed as a plane, and the boundary of the air inlet 10 may be a square, and one end of the first air guide surface 31 facing the air inlet 10, one end of the second air guide surface 32 facing the air inlet 10, one end of the third air guide surface 33 facing the air inlet 10 and one end of the fourth air guide surface 34 facing the air inlet 10 may jointly define the boundary of the air inlet 10, that is, the first to third plane sections 331 and the fourth air guide surface 34 are perpendicular to each other and jointly construct a partial section of the cubic air guide channel 30, so that the airflow can smoothly enter the air guide channel 30.
[0054] In some embodiments, Figure 1As shown, the outer periphery of the air inlet 10 is provided with a first annular flange 40 surrounding the air inlet 10, and the first annular flange 40 has a mounting hole 41. By setting the first annular flange 40, it can be set in close contact with the body and located at the outer periphery of the air outlet of the body, and the mounting hole 41 can be provided for bolts to pass through to be installed and connected with the body to ensure the air guiding effect of the air guide device 1. For example, the mounting holes 41 can be multiple and spaced to ensure the reliability of the installation of the air guide device 1 and the body, and at the same time, it can ensure that the air conditioning wind can smoothly pass through the air inlet 10 into the air guide channel 30. In the description of this application, the meaning of "multiple" is two or more.
[0055] In some embodiments, Figure 1 As shown, the outer periphery of the air outlet 20 is provided with a second annular flange 50 surrounding the air outlet 20. For example, the cross section of the second annular flange 50 can be a circular ring. By providing the second annular flange 50, the hose can be covered with the second annular flange 50 to ensure the installation reliability of the hose and the air guide device 1, so as to ensure the heat exchange effect.
[0056] For example, the main body may be made of fiberglass, which has the advantages of high structural strength and rigidity, good heat resistance, and low cost, and can ensure the wind guiding effect and help reduce the cost of the wind guiding device 1.
[0057] In some embodiments, the air guide device 1 further includes a heat preservation layer (not shown), which is attached to the outer peripheral wall of the body. By providing heat preservation cotton, the airflow in the air guide duct can be kept warm, so as to improve the heat exchange effect.
[0058] The vehicle air conditioner of the second aspect embodiment of the present application includes the air guide device 1 and the body of the vehicle air conditioner, the air guide device 1 is installed on the body, and the air inlet 10 of the air guide device 1 is arranged opposite to the air outlet of the body. The vehicle air conditioner may also include a hose, and the air-conditioned air blown out of the body may first change the flow direction of the airflow through the air guide device 1, and then further change the flow direction of the airflow through the hose according to actual needs, so as to guide the air-conditioned air blown out of the body into the passenger compartment. The vehicle air conditioner thus arranged has a good air guiding effect, and can ensure the wind speed and air volume of the cold or hot air delivered to the passenger compartment, so as to improve the heat exchange efficiency. Among them, there may be multiple air outlets of the body, and the air guide device 1 and the hose may be multiple and arranged corresponding to the air outlets.
[0059] The vehicle of the third embodiment of the present application includes the above-mentioned vehicle air conditioner. The vehicle air conditioner has a good air guiding effect, which can ensure the wind speed and air volume of the cold or hot air delivered to the passenger compartment, and can improve the user experience.
