Description

Technical Field

[0001] The present application relates to the technical field of automobile air conditioners, and in particular to an air inlet structure with a compensating air outlet and an automobile air conditioner. Background Art

[0002] Car air conditioning includes external circulation state and internal circulation state: the external circulation state uses a fan to draw air outside the car into the car, so that the air passages outside and inside the car are in a flowing state; the internal circulation state closes the airflow channel outside the car, and the airflow drawn by the fan only comes from inside the car, thus forming an airflow circulation in the car.

[0003] The ventilation box of the car air conditioner is usually equipped with a compensation air vent, and the air entering from the compensation air vent is the air inside the car. In summer, when the air conditioner is cooling, the internal circulation is usually adopted, and the compensation air vent is used to increase the air intake, thereby improving the cooling effect of the car air conditioner. In winter, when the air conditioner is heating, the external circulation is usually adopted to reduce the fogging of the car windshield. The air entering from the compensation air vent is mixed with the external air to improve the heating effect in the external circulation state.

[0004] In the prior art, the compensation air vents are mostly arranged in the air inlet box and are located before the filter. The air entering from the external circulation air inlet, the internal circulation air inlet and the compensation air vent of the ventilation box will all pass through the filter. With respect to the above-mentioned related technologies, there is a problem that the location of the compensation air vent increases the workload of the filter, making the effect of the vehicle air conditioning worse. Summary of the invention

[0005] In order to solve the above-mentioned problem that the location setting of the compensation air outlet increases the workload of the filter and makes the vehicle air conditioning effect worse, the present application provides a vehicle air conditioner with a compensation air outlet.

[0006] In a first aspect, the present application provides an air inlet structure with a compensation air outlet, which adopts the following technical solution.

[0007] An air inlet structure with a compensation air outlet, comprising: The ventilation box is provided with an external circulation air inlet, an internal circulation air inlet, a compensation air outlet and an air outlet in sequence; An air conditioning filter element is mounted against the inner wall of the ventilation box and is located between the internal circulation air inlet and the compensation air outlet; and A damper and a driving member, wherein the damper is rotatably mounted on the inner wall of the ventilation box, and the driving member drives the damper to rotate to close the external circulation air inlet or the internal circulation air inlet.

[0008] By adopting the above technical solution, the driving member drives the damper to rotate, which can effectively switch the internal circulation state or the external circulation state. First, the air conditioning filter is located between the internal circulation air inlet and the compensation air inlet, so that the air flow entering from the compensation air inlet passes less through the air conditioning filter, thereby reducing the filtering burden of the air conditioning filter, and further increasing the service life of the air conditioning filter. Second, compared with setting the air conditioning filter after the compensation air inlet, the wind entering the compensation air inlet will impact the air conditioning filter, thereby making the wind noise in the air intake structure larger. The compensation air inlet is set after the air conditioning filter, which can reduce the wind noise generated by the air flow impacting the filter. Third, the air conditioning filter is set between the compensation air inlets to act as a partition, so that the compensation air inlet and the external circulation air inlet are set "in parallel". By parallel connection, the compensation air inlet and the external circulation air inlet are separated independently, reducing the possibility of leakage of the compensation air in the car from the compensation air inlet to the external circulation air inlet, thereby avoiding the loss of cold air or heating in the car. Fourth, the location of the air conditioning filter and the compensation air outlet can further save energy. Since the airflow entering from the compensation air outlet is the airflow inside the car, and the airflow inside the car has been filtered to meet the standards when entering from outside the car, it does not need to be filtered multiple times. The compensation air at the compensation air outlet can delay filtering, which can further save energy. Fifth, the setting of the compensation air outlet increases the air volume of the internal and external circulation, thereby effectively improving the cooling or heating effect of the entire air conditioner.

[0009] Optionally, the plane where the compensation air outlet is located is not coplanar with the plane where the air outlet is located, and an air guide net is provided at the compensation air outlet, and the extension direction of the mesh holes in the air guide net is toward the air outlet.

[0010] By adopting the above technical solution, the direction of the mesh in the air guide net can effectively guide the airflow to the air outlet. By shortening the flow path of the airflow from the compensation air outlet to the air outlet, the flow rate of the airflow at the compensation air outlet can be effectively increased, and increasing the airflow flow rate can increase the air volume, thereby further improving the air conditioning effect.

[0011] Optionally, an air outlet surface of the air conditioning filter element is parallel to an extension direction of the mesh holes.

[0012] By adopting the above technical solution, the air outlet surface of the air conditioning filter is parallel to the extension direction of the mesh, which can further reduce the impact of the air flow entering from the compensation air outlet on the air conditioning filter, thereby further reducing the filtering burden of the air conditioning filter.

[0013] Optionally, the distances between the air outlet surface of the air conditioning filter and the air guide net at two ends in a direction perpendicular to the extending direction of the mesh holes are unequal.

[0014] By adopting the above technical solution, the air conditioning filter element can reduce the impact of the air flow entering from the compensation air outlet on the air conditioning filter element through the above arrangement, and can further increase the area of ​​the air conditioning filter element installed in the ventilation box, thereby improving the filtering efficiency of the air flow entering from the external circulation air inlet or the internal circulation air inlet. Increasing the area can also further reduce the concentrated impact of the air flow on the air conditioning filter element, thereby further reducing wind noise.

[0015] Optionally, the mesh shape of the air guide net is hexagonal, and the meshes are arranged in a uniform array.

[0016] By adopting the above technical solution, first, compared with setting the mesh as a circle, the hexagon can maximize the use of the ventilation area of ​​the air guide net and improve the ventilation efficiency. Second, the setting of the hexagonal mesh has better structural strength and stability than other shapes (such as a circle) under the same material. Because the edges of the hexagon are straighter, it is conducive to dispersing external stress and improving the overall strength of the air guide net. Third, the hexagonal mesh can cause multiple reflections and scattering of sound waves, which helps to disperse the sound waves in all directions, reduce the directionality of the sound waves, and thus have a certain noise reduction effect.

[0017] Optionally, a cover plate is further included, wherein the ventilation box is provided with a mounting hole at the air conditioning filter element, and the cover plate is detachably connected to one side of the air conditioning filter element. The cover plate covers or is away from the mounting hole so that the air conditioning filter element can be inserted into or removed from the ventilation box.

[0018] By adopting the above technical solution, the installation hole improves the convenience of disassembling, cleaning or replacing the air conditioning filter element. The cover plate can seal the air conditioning filter element in the ventilation box to reduce the possibility of it falling out.

[0019] Optionally, the air conditioning filter element includes a plurality of rotatably connected filter element bodies, and the filter element body can rotate toward the direction approaching the outer wall of the ventilation box after being pulled out of the ventilation box.

[0020] By adopting the above technical solution, during the vehicle assembly process, the installation position of the ventilation structure of the vehicle air conditioner is limited, especially other structures may be arranged around the installation hole to restrict the extraction of the air conditioner filter. The multiple rotatably connected filter bodies improve the convenience of extracting, replacing or cleaning the air conditioner filter.

[0021] Optionally, the mounting hole is set to be "L"-shaped, including a first through hole and a second through hole located on the side of the first through hole, the first through hole is adapted to the length of the filter element body, and the second through hole is adapted to the width of the filter element body farthest from the first through hole.

[0022] By adopting the above technical solution, when the space perpendicular to the extension direction of the first through hole is limited, the air conditioning filter element can be taken out from the extension direction perpendicular to the second through hole. Therefore, the "L"-shaped installation hole further improves the convenience of installing or removing the air conditioning filter element.

[0023] Optionally, a clamping part is fixedly installed on one side of the cover plate, and the clamping part includes a "V"-shaped deformation portion and a clamping part formed by bending the deformation portion toward one side, and an abutting part is provided at a position of the ventilation box opposite to the clamping part, and the clamping part abuts against the abutting part.

[0024] By adopting the above technical solution, the position of the clamping part can be moved by pressing the deformation part, and releasing the deformation part can make the clamping part abut against the abutting part, thereby improving the convenience of disassembly and assembly of the cover plate.

[0025] In a second aspect, the present application provides a vehicle air conditioner, which adopts the following technical solution.

[0026] A vehicle air conditioner with a compensating air outlet comprises the above-mentioned air inlet structure with the compensating air outlet.

[0027] By adopting the above technical solution, the vehicle air conditioner can effectively increase the service life of the air conditioning filter, and can effectively reduce wind noise and improve driving comfort. At the same time, the vehicle air conditioner can also reduce energy consumption and effectively improve the cooling or heating effect of the air conditioner. Finally, the air conditioning filter of the vehicle air conditioner is easy to disassemble and install, and is not limited by the installation space in the car.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. The position of the air conditioning filter can reduce the filtering burden of the air conditioning filter, increase the service life of the air conditioning filter, reduce wind noise, act as a partition and reduce the leakage of cold or hot air, save energy and significantly improve the cooling or heating effect of the air conditioner; 2. The air guide net can shorten the flow path of the air from the compensation air outlet to the air outlet, speed up the flow speed of the air at the compensation air outlet, and further improve the air conditioning effect; 3. The setting of the air conditioning filter and cover plate improves the convenience of disassembly, cleaning or replacement of the air conditioning filter, and is relatively less affected by the limitation of other structures in the vehicle.

[0035] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0036] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] The embodiments of the present application disclose a ventilation structure with a compensating air outlet and a vehicle air conditioner.

[0038] In a first aspect, an embodiment of the present application discloses a ventilation structure having a compensation air outlet.

[0039] Reference Figure 1 and Figure 2 A ventilation structure with a compensation air outlet includes a ventilation box 1, an air conditioning filter element 2, a damper 3, a driving member 4 and a cover plate 5.

[0040] Reference Figure 1 and Figure 2The ventilation box 1 is provided with an external circulation air inlet 11, an internal circulation air inlet 12, a compensation air outlet 13 and an air outlet 14 in sequence. The plane where the compensation air outlet 13 is located is not coplanar with the plane where the air outlet 14 is located. The external circulation air inlet 11 is connected to the air outside the car, and the internal circulation air inlet 12 and the compensation air outlet 13 are connected to the air inside the car.

[0041] In this embodiment, the ventilation box 1 is of a special shape to adapt to the relevant vehicle model. The external circulation air inlet 11 and the air outlet 14 are located at both ends of the ventilation box 1, and the compensation air outlet 13 and the internal circulation air inlet 12 are both located on the side wall of the ventilation box 1.

[0042] Reference Figure 3 The air conditioning filter element 2 is mounted against the inner wall of the ventilation box 1 and is located between the internal circulation air inlet 12 and the compensation air outlet 13 .

[0043] Reference Figure 2 and Figure 3 The damper 3 is rotatably mounted on the inner wall of the ventilation box 1, and the driving member 4 drives the damper 3 to rotate to close the external circulation air inlet 11 or the internal circulation air inlet 12. The driving member 4 is mounted on the outer wall of the ventilation box 1, and the driving member 4 can be a stepper motor or other motor that can rotate. The driving member 4 drives the damper 3 to rotate so that the air conditioner can switch between the following two states.

[0044] Internal circulation state: the driving member 4 drives the damper 3 to rotate and block the external circulation air inlet 11. At this time, the automobile air conditioner is in the internal circulation state. That is, the air flow inside the automobile enters the ventilation box 1 from the internal circulation air inlet 12 and the compensation air outlet 13 respectively. The air flow entering from the internal circulation air inlet 12 passes through the air conditioning filter 2 and then exits from the air outlet 14. The air flow entering from the compensation air outlet 13 directly exits from the air outlet 14.

[0045] External circulation state: the driving member 4 drives the damper 3 to block the internal circulation air inlet 12, and the automobile air conditioner is in the external circulation state. That is, the airflow outside the automobile enters the ventilation box 1 from the external circulation air inlet 11 and the compensation air outlet 13 respectively, and the airflow entering from the external circulation air inlet 11 passes through the air conditioning filter 2 and then exits from the air outlet 14, and the airflow entering from the compensation air outlet 13 directly exits from the air outlet 14.

[0046] Through the above structure, firstly, no matter the automobile air conditioner is in the external circulation state or the internal circulation state, the airflow entering from the compensation air port 13 is less likely to be filtered by the air conditioner filter element 2. Therefore, the filtering burden of the air conditioner filter element 2 can be effectively reduced, thereby increasing the service life of the air conditioner filter element 2.

[0047] The air entering the compensation air outlet 13 does not need to be filtered in time. If it is filtered multiple times, it will only increase the filtering burden of the air conditioning filter element 2, thereby reducing the cooling and heating effects of the air conditioner. The reason is: First, the airflow entering from the compensation air outlet 13 is the airflow inside the vehicle, and the airflow inside the vehicle has been filtered and meets the standards when entering from outside the vehicle, and does not need to be filtered multiple times.

[0048] Second, the compensation air at the compensation air outlet 13 and the air intake at the internal circulation air inlet 12 are both from the vehicle and return to the vehicle. Therefore, in the internal circulation state, part of the compensation air can also enter from the internal circulation air inlet 12 and pass through the air conditioning filter 2, so the compensation air can be filtered later. Delayed filtering can further save energy and resources.

[0049] Secondly, the position of the air conditioning filter 2 can reduce the wind noise in the ventilation structure. Compared with setting the air conditioning filter 2 after the compensation air port 13, the wind entering from the external circulation air inlet 11 or the internal circulation air inlet 12 and the compensation air port 13 will impact the air conditioning filter 2 in a concentrated manner, resulting in greater wind resistance, and thus greater wind noise in the air intake structure. However, when the compensation air port 13 is set after the air conditioning filter 2, the airflow entering from the compensation air port 13 will impact the filter less, thereby reducing some of the wind noise.

[0050] Finally, the air conditioning filter 2 is arranged between the compensation air vents 13 to act as a partition, so that the compensation air vents 13 are arranged "in parallel" with the external circulation air inlet 11. That is, the compensation air vents 13 are separated from the external circulation air inlet 11, reducing the possibility of leakage of the compensation air in the car from the compensation air vents 13 to the external circulation air inlet 11, thereby preventing the loss of cold air or heating in the car.

[0051] Reference Figure 1 and Figure 3 The compensation air outlet 13 is covered with an air guide net 6, and the extending direction of the mesh in the air guide net 6 is toward the air outlet 14. The air guide net 6 can be made of a hard material. The air guide net 6 can change the flow direction of the airflow, so that the airflow flows from the compensation air outlet 13 to the air outlet 14 along the shortest distance. By reducing the flow distance of the airflow, the flow speed of the airflow can be effectively increased in the same time, thereby increasing the air volume, thereby improving the cooling or heating effect of the entire air conditioner.

[0052] The mesh shape of the air guide net 6 is hexagonal, and the meshes are arranged in a uniform array. Compared with setting the meshes as circular, the hexagonal shape can effectively utilize the ventilation area of ​​the air guide net 6, thereby increasing the ventilation volume. At the same time, the hexagonal shape also has a strong bearing capacity and can effectively resist the impact of the airflow at the compensation air outlet 13.

[0053] Reference Figure 3 and Figure 4 , the air outlet surface of the air conditioning filter 2 is parallel to the extending direction of the mesh of the air guide net 6. The direction of the air conditioning filter 2 can further prevent the airflow passing through the mesh from passing through the air conditioning filter 2, thereby reducing the filtering burden of the air conditioning filter 2 and improving the filtering efficiency of the air conditioning filter 2.

[0054] In this embodiment, the air outlet surface of the air conditioning filter element 2 is also at two ends perpendicular to the extending direction of the mesh, and the distances from the air guide net 6 are not equal. Figure 4 Taking the perspective as an example, the air conditioning filter element 2 is tilted on both sides and further tilted on both sides. The tilting of the air conditioning filter element 2 in two directions can further increase the area of ​​the air conditioning filter element 2, thereby improving the filtering efficiency of the air conditioning filter element 2.

[0055] Reference Figure 5 and Figure 6 The ventilation box 1 is provided with a mounting hole 15 at the air conditioning filter element 2, and the cover plate 5 is detachably connected to one side of the air conditioning filter element 2. The cover plate 5 covers or is away from the mounting hole 15 so as to insert or remove the air conditioning filter element 2 from the ventilation box 1.

[0056] After long-term use, the air conditioning filter 2 will accumulate a lot of dust and impurities, which will reduce the filtering efficiency of the air conditioning filter 2 on the one hand, and also make the air entering the interior of the car produce a certain odor on the other hand. Therefore, the installation hole 15 and the cover plate 5 can improve the convenience of disassembly and assembly of the air conditioning filter 2.

[0057] In the assembly of a complete vehicle, the installation positions of the ventilation structures of different vehicle models are different. When the disassembly and assembly space around the mounting hole 15 is limited, the air conditioning filter element 2 cannot be effectively extracted.

[0058] Therefore, in this application, reference is made to Figure 5 and Figure 6 The air conditioning filter element 2 includes a plurality of rotatably connected filter element bodies 21, and the filter element bodies 21 can rotate toward the outer wall of the ventilation box 1 after being withdrawn from the ventilation box 1. In this embodiment, two filter element bodies 21 are provided.

[0059] The mounting hole 15 is configured to be in an “L” shape, including a first through hole 151 and a second through hole 152 located on the side of the first through hole 151 . The first through hole 151 is adapted to the length of the filter element body 21 , and the second through hole 152 is adapted to the width of the filter element body 21 farthest from the first through hole 151 .

[0060] When taking out the air conditioning filter 2, first pull out the cover plate 5 to move part of the filter body 21 away from the mounting hole 15. When the space perpendicular to the extension direction of the first through hole 151 is limited, the filter body 21 is rotated toward the outer wall of the ventilation box 1, that is, the filter body 21 is rotated downward or upward and bent. After bending, the filter body 21 is pulled out again in the direction perpendicular to the extension direction of the first through hole 151. The pulling and bending can be repeated multiple times according to the number of filter bodies 21 until all are pulled out.

[0061] Of course, if the width of the filter element body 21 farthest from the first through hole 151 is greater than the straight-line distance between the mounting hole 15 and the structure outside the mounting hole 15, the air conditioning filter element 2 still cannot be effectively removed. At this time, the filter element can be removed in a direction perpendicular to the second through hole 152. That is, if the air conditioning filter element 2 cannot be effectively removed from the first through hole 151, the direction can be adjusted to remove the air conditioning filter element 2 from the second through hole 152.

[0062] The shape of the mounting hole 15 and the structural arrangement of the air conditioning filter 2 enable the air conditioning filter 2 to be effectively removed in a relatively small space. Therefore, the ventilation structure of the present application can reduce the volume of the ventilation box 1 due to the relatively small space required for disassembly and assembly of the air conditioning filter 2, and thus can be adapted to different vehicle models.

[0063] In order to facilitate the installation of the air conditioning filter element 2, in this embodiment, a mounting frame (combined with Figure 3 ), thereby being able to effectively support the air conditioning filter element 2, so that the air conditioning filter element 2 does not rotate after being installed in the ventilation box 1, thereby being able to effectively filter the air.

[0064] Reference Figure 5 and Figure 6 A clamping part 7 is fixedly mounted on one side of the cover plate 5, and the clamping part 7 includes a "V"-shaped deformation part 71 and a clamping part 72 formed by bending the deformation part 71 toward one side. An abutting part 16 is provided at a position of the ventilation box 1 opposite to the clamping part 72, and the clamping part 72 abuts against the abutting part 16. When disassembling and assembling the cover plate 5, the clamping part 72 can be moved by pressing the deformation part 71. After placing the cover plate 5 at a position corresponding to the mounting hole 15 of the ventilation box 1, the clamping part 72 is released, and the deformation part 71 is reset to enable the clamping part 72 to effectively abut against the abutting part 16, thereby improving the convenience of disassembling and assembling the cover plate 5. Figure 2 The state after the engaging portion 72 abuts against the abutting portion 16 is shown.

[0065] Two groups of the clamping members 7 can be provided, so as to improve the stability of the cover plate 5 covering the outside of the mounting hole 15 .

[0066] The implementation principle of this embodiment is: During operation, the driving member 4 drives the damper 3 to rotate so as to switch the internal circulation state or the external circulation state. Part of the airflow enters the ventilation box 1 from the external circulation air inlet 11 or the internal circulation air inlet 12, and is filtered by the air conditioning filter element 2 and then exits from the air outlet 14. Part of the airflow enters from the compensation air outlet 13 and directly exits from the air outlet 14. This reduces the filtering burden of the air conditioning filter element 2 and improves the cooling and heating effects of the air conditioner.

[0067] When disassembling, press the clamping member 7 to disassemble the cover plate 5, and pull the cover plate 5 away from the installation hole 15. When the extraction space is limited, rotate the filter element body 21 and extract the air conditioning filter element 2 from the first through hole 151 or the second through hole 152 according to the extraction space. The installation of the air conditioning filter element 2 can be carried out by the opposite operation of extracting the air conditioning filter element 2.

[0068] In a second aspect, an embodiment of the present application also discloses a vehicle air conditioner.

[0069] Reference Figure 1 A vehicle air conditioner includes the above-mentioned air inlet structure with a compensation air outlet and a fan (not shown in the figure), and the air outlet 14 of the ventilation box 1 is connected to the fan. The fan draws airflow in the air inlet structure, thereby effectively cooling or heating.

[0070] The vehicle air conditioner of the embodiment of the present application can effectively increase the service life of the air conditioning filter 2, and can effectively reduce wind noise and improve driving comfort. At the same time, the vehicle air conditioner can also reduce energy consumption and effectively improve the cooling or heating effect of the air conditioner. Finally, the air conditioning filter 2 of the vehicle air conditioner is easy to disassemble and install, and is not limited by the installation space in the vehicle. Since the air conditioning filter 2 can be pulled out in a relatively small space, the adaptability of the vehicle air conditioner to different models during installation is further improved.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
