Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an air conditioning unit for automobiles. Background Technology

[0002] Automotive air conditioning is a ventilation system used to adjust and control the temperature, humidity, air cleanliness, and airflow inside a car cabin to the optimal state, providing a comfortable riding environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and playing an important role in ensuring safe driving.

[0003] As an important component of the car's air conditioning system, the air conditioning unit draws in outside air after the driver turns on the air conditioning. The air first passes through the filter element to remove dust, pollen and other impurities, and then passes through the evaporator core (cooling) and the heating core (heating). The total air volume and the air volume distribution of each air outlet are controlled by adjusting the damper angle.

[0004] The air intake of the air conditioning unit is usually located in the drainage channel below the wiper cover in the front compartment. When the vehicle is driving in heavy rain or parked outdoors with the air conditioning on, rainwater flowing in through the wiper shaft mounting hole will be sucked into the air conditioning unit, causing water to enter the air conditioning unit. This can lead to mold growth on the filter element, and in severe cases, it can even wet electrical components such as the blower motor, causing corrosion, short circuits, and ultimately causing the air conditioning function to fail. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problem in the prior art where, when a vehicle is driving in heavy rain or parked outdoors with the air conditioning on, rainwater flowing into the wiper shaft mounting hole is sucked into the air conditioning unit, causing water to enter the air conditioning unit, leading to mold growth on the filter element, and in severe cases, water may drip onto electrical components such as the blower motor, causing corrosion, short circuits, and ultimately causing the air conditioning function to fail.

[0006] To solve the above-mentioned technical problems, the present invention discloses an air conditioning unit for automobiles. The air conditioning unit is disposed in the front compartment of the automobile and located below the windshield. The air conditioning unit includes a housing with an air inlet that opens upward in the height direction of the automobile.

[0007] The air conditioning unit also includes a water-receiving baffle located inside the air inlet. The water-receiving baffle is set on the side wall of the air inlet near the windshield. The water-receiving baffle has a lower end and an upper end. In the depth direction of the air inlet, the upper end is above the lower end. The lower end abuts against the inner surface of the side wall of the air inlet near the windshield. The two ends of the water-receiving baffle abut against the inner surface of the corresponding side wall of the air inlet. In the length direction of the vehicle, the water-receiving baffle extends obliquely from the lower end to the upper end in the direction away from the windshield. The water-receiving baffle and the side wall of the corresponding side of the air inlet form a water-retaining structure.

[0008] Using the above technical solution, the air conditioning unit is installed below the windshield, facilitating air circulation. Simultaneously, a water-receiving baffle is installed inside the air inlet, with its lower end closely attached to the inner surface of the air inlet's side wall, ensuring that rainwater cannot seep in from the bottom. Along the length of the vehicle, the water-receiving baffle extends at an angle away from the windshield, conforming to the natural direction of rainwater runoff. This effectively collects and guides rainwater to a water-storage structure formed by the side wall corresponding to the air inlet, temporarily storing any rainwater that might seep into the air inlet. This prevents further intrusion into the air conditioning unit, which could damage critical components such as the filter element and blower motor, reducing the air conditioning failure rate caused by rainwater and lowering maintenance costs. Furthermore, because the water-receiving baffle is located inside the air inlet, it does not increase the space occupied by the air conditioning unit, making it easier to arrange in the front compartment.

[0009] The present invention also discloses an air conditioning unit for automobiles, wherein the upper end of the water receiving baffle is flush with the upper edge of the side wall of the air inlet in the depth direction of the air inlet.

[0010] By adopting the above technical solution, the upper end of the water baffle is flush with the upper edge of the side wall of the air inlet, which will not occupy additional space above the air inlet and can reduce the resistance of airflow when passing through the air inlet.

[0011] The present invention also discloses an air conditioning unit for automobiles, wherein the water receiving baffle is configured as a straight plate structure.

[0012] The angle between the straight plate structure and the side wall of the air inlet near the windshield is in the range of 30° to 75°.

[0013] By adopting the above technical solution, the water-receiving baffle is designed as a straight plate structure, which allows rainwater to be guided more smoothly into the water storage structure during its descent, reducing the possibility of rainwater accumulation and dripping on the baffle. Furthermore, this type of baffle has a simple structure, making it easier to manufacture and ensuring the stability and durability of the structure during installation.

[0014] The angle between the water-receiving baffle and the side wall of the air intake near the windshield is set within the range of 30° to 75°. When the angle is too small (less than 30°), rainwater may not be effectively guided to the water-retaining structure, but instead drips or splashes along the edge of the baffle, increasing the risk of rainwater entering the air conditioning unit. When the angle is too large (greater than 75°), although rainwater can be guided to the water-retaining structure, the baffle occupies more space and may increase air resistance when flowing through the air intake. Therefore, an angle range of 30° to 75° is the optimal choice that balances waterproofing, space utilization, and airflow.

[0015] The present invention also discloses an air conditioning unit for automobiles, wherein the water receiving baffle is configured as an arc-shaped plate structure, and the arc-shaped plate structure protrudes smoothly along the side wall facing away from the air inlet and closer to the windshield.

[0016] The radius of the arc-shaped plate structure is in the range of 15 mm to 25 mm.

[0017] Using the above technical solution, the water-receiving baffle is designed as an arc-shaped plate structure. This structure protrudes smoothly along the side wall facing away from the air inlet and closer to the windshield, which conforms to the natural direction of rainwater sliding down. It can also more effectively guide rainwater to flow into the water storage structure, reducing the accumulation and dripping of rainwater on the water-receiving baffle.

[0018] The radius of the arc-shaped plate structure is set within the range of 15 mm to 25 mm. When the radius of the arc is too small (less than 15 mm), the arc plate may be too steep and cannot effectively guide rainwater, or may even cause rainwater to accumulate or splash on the arc plate. When the radius of the arc is too large (greater than 25 mm), although rainwater can be guided to the water storage structure, the arc plate will occupy more space and may increase the resistance when air flows through the air inlet.

[0019] The present invention also discloses an air conditioning unit for automobiles, wherein the water receiving baffle is configured as a curved plate structure, and the side surface of the curved plate structure near the air inlet gradually concave from both sides to the middle to form an inward curved surface.

[0020] The radius of curvature of the concave surface is in the range of 680 mm to 700 mm.

[0021] Using the above technical solution, the water baffle is designed as a curved plate structure. The side surface of this structure near the air inlet gradually concaves from both sides to the middle to form an inward curved surface, which conforms to the principle of aerodynamics. This can reduce the resistance of airflow when passing through the air inlet, improve air conditioning efficiency, and more effectively guide rainwater to the water storage structure to prevent rainwater from entering the air conditioning unit.

[0022] The radius of the concave surface is set within the range of 680 mm to 700 mm. Within this radius, the water baffle can effectively guide rainwater while ensuring that air can flow smoothly through the air inlet without negatively affecting the working efficiency of the air conditioning unit.

[0023] The present invention also discloses an air conditioning unit for automobiles, wherein a plurality of drain outlets penetrating the side wall are provided at intervals above the lower end of the water receiving baffle on the side wall of the air inlet.

[0024] With the above technical solution, the drain outlet is located on the side wall of the air inlet, above the lower end of the water-receiving baffle. This ensures that when rainwater is guided to its lower end by the water-receiving baffle, it can be smoothly discharged through the drain outlet without accumulating in the water storage structure, thus preventing excessive water accumulation in the water storage structure from overflowing from the upper end of the water-receiving baffle into the air conditioning unit.

[0025] Furthermore, the drain outlets penetrate the side walls, meaning that water accumulated within the water storage structure can flow directly from inside the air conditioning unit to the outside without needing to go through other complex drainage systems. The spaced arrangement of multiple drain outlets ensures uniform and efficient drainage, more effectively dispersing and expelling rainwater and preventing localized water accumulation.

[0026] The present invention also discloses an air conditioning unit for automobiles, wherein the drain outlet extends downward along the direction away from the water receiving baffle and inclined to the depth direction of the air inlet.

[0027] The angle between the extension direction of the drain outlet and the depth direction of the air inlet is within the range of 30° to 60°.

[0028] In the depth direction of the air inlet, the distance between the lower end of the water baffle and the lower edge of the drain outlet is in the range of 2 mm to 5 mm.

[0029] By adopting the above technical solution, the inclined extension design of the drain outlet allows rainwater to flow out more smoothly along the drain outlet, reducing the possibility of water accumulation and improving drainage efficiency.

[0030] The angle between the extension direction of the drain outlet and the depth direction of the air inlet is set within the range of 30° to 60° to ensure that rainwater can flow smoothly out of the drain outlet without causing poor drainage or water accumulation due to an excessively large or small angle. In the depth direction of the air inlet, the distance between the lower end of the water receiving baffle and the lower edge of the drain outlet is set within the range of 2 mm to 5 mm to ensure that after the rainwater is guided to the lower end by the water receiving baffle, it can flow directly into the drain outlet without dripping to other locations or accumulating inside the air conditioning unit due to an excessively large distance.

[0031] The present invention also discloses an automobile in which the front end of the windshield is fixedly connected to the front compartment. The automobile also includes any of the above-mentioned air conditioning units for automobiles, which are disposed in the front compartment and located below the windshield.

[0032] Specifically, in one embodiment, the front compartment includes a wiper cover and a lower cover that are fixedly disposed sequentially from top to bottom in the height direction of the vehicle, and the front end of the windshield is fixedly connected to the wiper cover of the front compartment.

[0033] The car also includes a windshield wiper system, which includes windshield wipers. The wiper cover has wiper holes, and the windshield wipers are rotatably connected to the wiper cover via a connecting shaft that passes through the wiper holes. In the width direction of the car, the water baffle is located in the air intake at a position corresponding to the wiper holes.

[0034] The depth of the air intake is parallel to the height of the car.

[0035] Using the above technical solution, the air conditioning unit of this car is located in the front compartment, below the windshield. Furthermore, in the width direction of the car, the water-receiving baffle is positioned within the air intake corresponding to the wiper holes. When the wipers are working, even if water droplets splash up, they will be effectively intercepted by the baffle and guided into the water storage structure, preventing them from entering the air conditioning unit. This ensures that the normal operation of the air conditioning unit is not affected by rainwater, providing a comfortable driving environment for the driver and reducing the risk of air conditioning unit malfunction.

[0036] The beneficial effects of this utility model are as follows:

[0037] This utility model discloses an air conditioning unit for automobiles. This unit features a water-receiving baffle inside the air inlet. The lower end of the baffle is tightly attached to the inner surface of the side wall of the air inlet, ensuring that rainwater cannot seep in from the bottom. Along the length of the vehicle, the baffle extends obliquely away from the windshield, conforming to the natural direction of rainwater runoff. This effectively collects and guides rainwater to a water-storing structure formed by the side wall corresponding to the air inlet, temporarily storing rainwater that may seep into the air inlet and preventing further intrusion into the air conditioning unit, which could damage critical components such as the filter element and blower motor. This reduces the air conditioning failure rate caused by rainwater and lowers maintenance costs. Furthermore, because the baffle is located inside the air inlet, it does not increase the space occupied by the air conditioning unit, making it easier to arrange in the front compartment.

[0038] Furthermore, the sidewall of the air inlet is equipped with multiple through-holes at intervals above the lower end of the water-receiving baffle, further improving the drainage performance of the air conditioning unit. Even in heavy rain, it ensures that water will not accumulate inside the air conditioning unit. In other words, the water-receiving baffle guides rainwater to its lower end, while the drains discharge this rainwater out of the air inlet. The synergistic effect of the two ensures that the inside of the air conditioning unit remains dry and clean. Attached Figure Description

[0055] As mentioned in the background section, when a vehicle is driving in heavy rain or parked outdoors with the air conditioning on, rainwater flowing into the wiper shaft mounting hole can be sucked into the air conditioning unit, causing water to enter the unit and leading to mold growth on the filter element. In severe cases, the water can even reach electrical components such as the blower motor, causing corrosion and short circuits.

[0056] Therefore, this utility model provides an air conditioning unit for automobiles. This unit features a water-receiving baffle inside the air inlet, with a water-collecting structure formed between the baffle and the side wall of the air inlet. When rainwater splashes into the air inlet, it is guided by the baffle into the water-collecting structure, preventing further intrusion into the air conditioning unit and reducing the air conditioning failure rate caused by rainwater, thus lowering maintenance costs. Furthermore, because the baffle is located inside the air inlet, it does not increase the space occupied by the air conditioning unit, making it easier to arrange in the front compartment.

[0057] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0058] like Figure 1 and Figure 2 As shown, this embodiment provides an air conditioning unit 10 for automobiles. The air conditioning unit 10 is installed in the front compartment of the automobile and located below the windshield 20. The air conditioning unit 10 includes a housing 100, which has an air inlet 110 that opens upward in the height direction of the automobile.

[0059] like Figure 3 and Figure 4 As shown, the air conditioning unit 10 also includes a water-receiving baffle 200 located inside the air inlet 110. The water-receiving baffle 200 is disposed on the side wall of the air inlet 110 near the windshield 20. The water-receiving baffle 200 has a lower end 220 and an upper end 210. In the depth direction Y of the air inlet 110, the upper end 210 is located above the lower end 220. The lower end 220 abuts against the inner surface of the side wall of the air inlet 110 near the windshield 20. The two ends 230 of the water-receiving baffle 200 abut against the inner surface of the corresponding side wall of the air inlet 110. In the length direction of the vehicle, the water-receiving baffle 200 extends obliquely from the lower end 220 to the upper end 210 in a direction away from the windshield 20. The water-receiving baffle 200 and the side wall of the corresponding side of the air inlet 110 form a water-retaining structure. It should be noted that, in this embodiment, the two ends 230 of the water receiving baffle 200 refer to the ends of the water receiving baffle 200 on both sides in the horizontal direction.

[0060] It should be noted that, as Figure 5As shown, the air conditioning unit 10 also includes other components such as a filter element 300, a blower 400, an evaporator core 500, and a heating core 600 within its housing 100. When the driver turns on the air conditioning, the blower 400 rotates to draw outside air into the air conditioning unit 10 through the air inlet 110. The air first passes through the filter element 300 to filter out dust, pollen, and other impurities, and then passes sequentially through the evaporator core 500 and the heating core 600 for heat exchange. For example, during the cooling process, the air exchanges heat with the medium in the evaporator core 500, absorbing heat from the air, and thus the cool air is discharged into the passenger cabin through the air outlet. During the heating process, the air exchanges heat with the medium in the heating core 600, releasing heat to the air, and thus the hot air is discharged into the passenger cabin through the air outlet. Regarding the multiple blade structures for adjusting airflow within the air duct of the air conditioning unit 10, this embodiment does not provide specific limitations on this aspect.

[0061] This air conditioning unit 10 has a water-receiving baffle 200 installed inside the air inlet 110. The lower end 220 of the water-receiving baffle 200 is in close contact with the inner surface of the side wall of the air inlet 110, ensuring that rainwater cannot seep in from the bottom. Along the length of the vehicle, the water-receiving baffle 200 extends obliquely away from the windshield 20, conforming to the natural direction of rainwater runoff. This effectively collects and guides rainwater to the water storage structure formed by the side wall of the water-receiving baffle 200 and the air inlet 110, temporarily storing rainwater that may seep into the air inlet 110 and preventing it from further intruding into the interior of the air conditioning unit 10 and damaging key components such as the filter element 300 and the blower motor 400. This reduces the air conditioning failure rate caused by rainwater and lowers maintenance costs. In addition, since the water-receiving baffle 200 is installed inside the air inlet 110, it does not increase the space occupied by the air conditioning unit 10, making it easier to arrange in the front compartment.

[0062] Specifically, in the depth direction Y of the air inlet 110, the upper end 210 of the water baffle 200 is flush with the upper edge of the side wall of the air inlet 110, which will not occupy additional space above the air inlet 110 and can reduce the resistance when the air flows through the air inlet 110.

[0063] The specific structure of the water baffle 200 will be described below.

[0064] A water-receiving baffle 200 is disposed inside the air inlet 110 and connected to the side wall of the air inlet 110. As its name suggests, the water-receiving baffle 200 is used to guide water droplets splashing into the air inlet 110 and prevent water from wetting other components inside the air conditioning unit 10. It should be noted that the connection method between the water-receiving baffle 200 and the side wall of the air inlet 110 can be adhesive, snap-fit, screw, or other commonly used fixing methods in the art. This embodiment does not specifically limit this method.

[0065] In order to improve the sealing of the water storage structure formed by the water receiving baffle 200 and the side wall of the air inlet 110, sealing gaskets are provided between the lower end 220 and the two side ends 230 of the water receiving baffle 200 and the corresponding side wall to prevent the water temporarily stored in the water storage structure from seeping into the housing 100 of the air conditioning unit 10.

[0066] In one embodiment, such as Figure 3 As shown, the water receiving baffle 200 is configured as a straight plate structure. That is, the cross-section of the water receiving baffle 200 is straight plate-shaped.

[0067] The angle between the straight plate structure and the side wall of the air inlet 110 near the windshield 20 is in the range of 30° to 75°. That is, the angle between the straight plate structure and the side wall of the air inlet 110 near the windshield 20 can be 30°, 45°, 60°, 75° or any other angle within the above range. Those skilled in the art can design according to actual conditions and specific needs. This embodiment does not make specific limitations in this regard.

[0068] In this embodiment, the water-receiving baffle 200 is configured as a straight plate structure, which allows rainwater to be guided more smoothly into the water storage structure during its descent, reducing the possibility of rainwater accumulation and dripping on the water-receiving baffle 200. Furthermore, this water-receiving baffle 200 has a simple structure, making it easier to manufacture and ensuring the installation stability and durability of the structure.

[0069] The angle between the water-receiving baffle 200 and the side wall of the air inlet 110 near the windshield 20 is set within the range of 30° to 75°. When the angle is too small (less than 30°), rainwater may not be effectively guided to the water-retaining structure, but instead drips or splashes along the edge of the water-receiving baffle 200, increasing the risk of rainwater entering the air conditioning unit 10. When the angle is too large (greater than 75°), although rainwater can be guided to the water-retaining structure, the water-receiving baffle 200 will occupy more space and may increase the resistance to airflow through the air inlet 110. Therefore, an angle range of 30° to 75° is the optimal choice that balances waterproofing, space utilization, and airflow.

[0070] In another embodiment, such as Figures 6 to 8 As shown, the water baffle 200 is configured as an arc-shaped plate structure, and the cross-section of the water baffle 200 protrudes smoothly along the side wall facing away from the air inlet 110 and close to the windshield 20.

[0071] The radius of the arc-shaped plate structure is in the range of 15 mm to 25 mm. That is, the radius of the arc-shaped plate structure can be 15 mm, 16 mm, 20 mm, 25 mm or any other length within the above range. Those skilled in the art can design it according to actual conditions and specific needs. This embodiment does not limit it to a single length.

[0072] In this embodiment, the water-receiving baffle 200 is designed as an arc-shaped plate structure. This structure protrudes smoothly along the side wall facing away from the air inlet 110 and close to the windshield 20, which conforms to the natural direction of rainwater sliding down. It can also more effectively guide rainwater to the water storage structure, reducing the accumulation and dripping of rainwater on the water-receiving baffle 200.

[0073] The radius of the arc-shaped plate structure is set within the range of 15 mm to 25 mm. When the radius of the arc is too small (less than 15 mm), the arc plate may be too steep and cannot effectively guide rainwater, or may even cause rainwater to accumulate or splash on the arc plate. When the radius of the arc is too large (greater than 25 mm), although rainwater can be guided to the water storage structure, the arc plate will occupy more space and may increase the resistance of airflow when passing through the air inlet 110.

[0074] In another embodiment, such as Figure 4 As shown, the water receiving baffle 200 is configured as a curved plate-like structure. The side surface of the curved plate-like structure near the air inlet 110 gradually concaves from both sides towards the middle to form an inwardly concave curved surface. Figure 4 (The cross-section shown by the dashed line). That is, the surface of the longitudinal section of the water receiving baffle 200 near the side wall is a concave curved surface.

[0075] The radius of the concave surface is in the range of 680 mm to 700 mm. That is, the radius of the concave surface can be 680 mm, 685 mm, 688 mm, 690 mm, 700 mm or any other length within the above range. Those skilled in the art can design it according to actual conditions and specific needs. This embodiment does not make specific limitations in this regard.

[0076] In this embodiment, the water baffle 200 is designed as a curved plate structure. The side surface of this structure near the air inlet 110 gradually concaves from both sides to the middle to form an inward curved surface, which conforms to the principle of aerodynamics. This can reduce the resistance of airflow when passing through the air inlet 110, improve air conditioning efficiency, and more effectively guide rainwater to the water storage structure to prevent rainwater from entering the air conditioning unit 10.

[0077] The radius of the concave surface is set within the range of 680 mm to 700 mm. Within this radius range, the water baffle 200 can effectively guide rainwater while ensuring that air can flow smoothly through the air inlet 110 without negatively affecting the working efficiency of the air conditioning unit 10.

[0078] It should be noted that when the longitudinal section of the water receiving baffle 200 is concave on the surface of the side wall, the cross section of the water receiving baffle 200 can be set as a straight plate or an arc shape. This embodiment does not limit this to a single shape.

[0079] Furthermore, the water storage structure formed by the side wall of the water receiving baffle 200 and the side corresponding to the air inlet 110 has a limited water storage capacity. If too much water accumulates in the water storage structure, it may overflow from the upper end 210 of the water receiving baffle 200. Therefore, in one embodiment, the side wall of the air inlet 110 is provided with a plurality of drain outlets 111 that penetrate the side wall at intervals above the lower end 220 of the water receiving baffle 200. The number of drain outlets 111 can be two, three, four or other numbers. This embodiment does not make a specific limitation on this.

[0080] In this embodiment, the drain outlet 111 is located on the side wall of the air inlet 110 and above the lower end 220 of the water-receiving baffle 200. This ensures that when rainwater is guided to its lower end 220 by the water-receiving baffle 200, it can be smoothly discharged through the drain outlet 111 without accumulating in the water storage structure, thus preventing excessive water accumulation in the water storage structure from overflowing from the upper end 210 of the water-receiving baffle 200 into the air conditioning unit 10. It should be noted that the air conditioning unit 10 is located in the front compartment of the car. Other components in the front compartment, such as the intercooler and engine, will not be damaged by a small amount of accumulated water, and the front compartment is not a sealed space, so the accumulated water will drain out from the front compartment.

[0081] Furthermore, the drain outlet 111 penetrates the side wall, meaning that water accumulated in the water storage structure can flow directly from the inside of the air conditioning unit 10 to the outside without going through other complex drainage systems. The multiple drain outlets 111 are spaced apart to ensure uniform and efficient drainage, more effectively dispersing and draining rainwater and avoiding localized water accumulation.

[0082] More specifically, such as Figure 7 As shown, in one embodiment, the drain outlet 111 extends downward along the direction away from the water receiving baffle 200 and inclined to the depth direction Y of the air inlet 110.

[0083] The angle α between the extension direction of the drain outlet 111 and the depth direction Y of the air inlet 110 is within the range of 30° to 60°. That is, the angle α between the extension direction of the drain outlet 111 and the depth direction Y of the air inlet 110 can be 30°, 35°, 40°, 45°, 50°, 60° or any other angle within the above range. Those skilled in the art can design according to actual conditions and specific needs. This embodiment does not make specific limitations in this regard.

[0084] In the depth direction Y of the air inlet 110, the distance between the lower end 220 of the water baffle 200 and the lower edge of the drain outlet 111 is in the range of 2 mm to 5 mm. That is, the distance between the lower end 220 of the water baffle 200 and the lower edge of the drain outlet 111 can be 2 mm, 2.4 mm, 3 mm, 5 mm or any other distance within the above range. Those skilled in the art can design according to actual conditions and specific needs. This embodiment does not make specific limitations in this regard.

[0085] In this embodiment, the inclined extension design of the drain outlet 111 allows rainwater to flow out more smoothly along the drain outlet 111, reducing the possibility of water accumulation and improving drainage efficiency.

[0086] The angle α between the extension direction of the drain outlet 111 and the depth direction Y of the air inlet 110 is set within the range of 30° to 60°, ensuring that rainwater can flow smoothly out of the drain outlet 111 without causing poor drainage or water accumulation due to an excessively large or small angle. In the depth direction Y of the air inlet 110, the distance between the lower end 220 of the water receiving baffle 200 and the lower edge of the drain outlet 111 is set within the range of 2 mm to 5 mm, ensuring that after the rainwater is guided to the lower end 220 by the water receiving baffle 200, it can flow directly into the drain outlet 111 without dripping to other locations or accumulating inside the air conditioning unit 10 due to an excessively large distance.

[0087] like Figure 8 As shown, in another alternative embodiment, the extension direction of the drain outlet 111 is perpendicular to the depth direction Y of the air inlet 110. This drain outlet 111 has a simple structure and reduces the difficulty of processing.

[0088] An embodiment of this utility model also discloses a car, such as Figure 1 As shown, the front end of the windshield 20 is fixedly connected to the front compartment. This type of vehicle also includes any of the above-mentioned air conditioning units 10 for automobiles. The air conditioning unit 10 is located in the front compartment and below the windshield 20.

[0089] Specifically, in one embodiment, the front compartment includes a wiper cover plate 30 and a lower cover plate 40 fixedly disposed sequentially from top to bottom in the height direction of the vehicle, and the front end of the windshield 20 is fixedly connected to the wiper cover plate 30 of the front compartment.

[0090] like Figure 6 As shown, the car also includes a windshield wiper system, which includes a windshield wiper 50. The windshield wiper cover 30 is provided with a windshield wiper hole 301. The windshield wiper 50 is rotatably connected to the windshield wiper cover 30 through the windshield wiper hole 301 via a connecting shaft 60. In the width direction of the car, the water baffle 200 is located in the air inlet 110 at a position corresponding to the windshield wiper hole 301.

[0091] It should be noted that the depth direction Y of the air inlet 110 of the air conditioning unit 10 is parallel to the height direction of the car.

[0092] In this embodiment, the air conditioning unit 10 of the vehicle is located in the front compartment and below the windshield 20. Furthermore, in the width direction of the vehicle, the water-receiving baffle 200 is located in the air intake 110 at a position corresponding to the wiper hole 301. When the wipers 50 are working, even if water droplets splash up, they will be effectively intercepted by the water-receiving baffle 200 and guided into the water storage structure, preventing them from entering the air conditioning unit 10. The normal operation of the air conditioning unit 10 is unaffected by rainwater, providing a comfortable driving environment for the driver and reducing the risk of malfunction of the air conditioning unit 10.

[0093] Of course, this embodiment does not limit the specific location of the air conditioning unit 10 in the front compartment of the vehicle, or other components in the front compartment of the vehicle.
