Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, specifically to a vehicle air conditioner and a car. Background Technology

[0002] Vehicle air conditioning is a device that cools, heats, and ventilates the air inside a vehicle, providing a comfortable riding environment, reducing driver fatigue, and improving driving safety. Currently, vehicle air conditioning systems mainly consist of a housing and an evaporator and condenser housed within it, as well as air outlets and return vents suitable for connection to the vehicle's exterior wall. Air from inside the vehicle enters the outdoor unit of the air conditioning system through the return vent, then passes through the evaporator, and finally returns to the vehicle through the air outlet. In existing technology, to prevent condensate generated during operation from flowing back into the vehicle through the air outlet or return vent, a drip tray is typically installed below the evaporator and connected to a drain pipe. The drain pipe then drains the water from the drip tray, thus reducing the possibility of condensate flowing back into the vehicle.

[0003] However, because the vehicle's drain pipe and drip tray have a connector, and due to the inherent bends in the assembly process, coupled with the drain pipe's rigid material and large bending radius, the drain pipe occupies a significant amount of space, severely impacting the space between the air conditioner and the vehicle's roof. After a period of vehicle use, the connection between the drain pipe and the air conditioner may age or even detach, leading to the uncontrolled drainage of condensate. Furthermore, the disassembly and reassembly of the drain pipe itself is quite complex during maintenance and after-sales service. Additionally, when the drip tray is located inside the air conditioner housing, if the water in the tray is not drained promptly, it may spill into the air vents or return vents when the vehicle is tilted, causing water to enter the vehicle and negatively impacting the user experience. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art in which the vehicle air conditioner uses a drain pipe to drain the condensate from the water tray, resulting in a large space occupation and the need for maintenance and replacement, thereby providing a vehicle air conditioner and car that occupy less space and do not require maintenance.

[0005] To address the aforementioned problems, a first aspect of the present invention provides a vehicle air conditioner, comprising: a housing, wherein an air outlet and an air return outlet are provided on the bottom wall of the housing; a first guide wall surrounding the air outlet and extending toward the interior of the housing; a first drain hole formed on the outer side of the first guide wall; a second guide wall surrounding the air return outlet and extending toward the interior of the housing; a second drain hole formed on the outer side of the second guide wall; a water collection tray disposed below the air outlet and the air return outlet, wherein a water-receiving cavity is formed on the water collection tray; and a third drain hole formed on the water collection tray and disposed near the housing.

[0006] Furthermore, the third drain hole is located at the edge of the water receiving tray.

[0007] Furthermore, the water receiving tray includes a first water receiving tray and a second water receiving tray, with the first water receiving tray arranged around the air outlet and the second water receiving tray arranged around the air return outlet.

[0008] Furthermore, the first water receiving tray and the first guide wall are an integral structure; the second water receiving tray and the second guide wall are an integral structure.

[0009] Furthermore, the connection between the first guide wall and the air outlet is intermittent welding; the connection between the second guide wall and the return air outlet is also intermittent welding.

[0010] Furthermore, a fourth drainage hole is provided on the bottom wall of the shell.

[0011] The second aspect of the present invention relates to an automobile, including a vehicle body and a vehicle roof; an in-vehicle air conditioner provided in the first aspect of the present invention; a first air vent and a second air vent, which are disposed on the vehicle roof and respectively corresponding to the air outlet and the air return vent.

[0012] Furthermore, the car also includes a sealing gasket, which is installed between the vehicle air conditioner and the roof of the car. The sealing gasket has a through hole in the center, which corresponds to the first air vent or the second air vent.

[0013] Furthermore, the sealing gasket is made of foamed rubber sponge.

[0014] Furthermore, the vehicle also includes a support block positioned between the housing and the roof.

[0015] The present invention has the following advantages:

[0016] 1. As can be seen from the above technical solution, the vehicle air conditioner of the first aspect of the present invention adds a first guide peripheral wall, a second guide peripheral wall, a first drain hole, a second drain hole, a water receiving tray, and a third drain hole to the housing. Water generated during the operation of the air conditioner first falls onto the housing and is blocked by the first guide peripheral wall when flowing to the air outlet. It then flows through the first drain hole formed on the outer side of the first guide peripheral wall into the water receiving tray, where it is stored and discharged through the third drain hole. Water flowing to the return air vent is blocked by the second guide peripheral wall and flows through the second drain hole formed on the outer side of the second guide peripheral wall into the water receiving tray, where it is stored and discharged through the third drain hole.

[0017] Therefore, in this invention, by placing the water collection tray at the bottom of the housing, the water collection tray can guide condensate. The water collection tray in the vehicle air conditioner of this invention can replace the drain pipe to discharge rainwater and condensate. This eliminates the need for the water collection tray to be connected to the drain pipe, avoiding the large area occupied and after-sales problems such as interface aging and detachment associated with installing a drain pipe. This allows for a more compact structure of the vehicle air conditioner and eliminates the need for maintenance and replacement of the drain pipe, thus improving the user experience. Furthermore, the water collection tray in this invention is located below the air outlet and return air vent. When the water collection tray is located inside the air conditioner housing, if the water in the tray is not drained in time, it may spill into the air outlet or return air vent when the vehicle body is tilted. However, the water collection tray in this application is located under the housing, so even if the vehicle body tilts or bumps during driving, the water in the tray can only be discharged through the third drain hole and will not enter the vehicle through the air outlet or return air vent.

[0018] 2. The drip tray includes a first drip tray and a second drip tray. The first drip tray surrounds the air outlet and receives water from the first drain hole, which is then discharged outwards through the third drain hole. The second drip tray surrounds the return air inlet and receives water from the second drain hole, which is then discharged outwards through the third drain hole. When the first and second drip trays are designed as separate units, they can specifically drain water from the air outlet and return air inlet of the housing. This prevents water from inside the housing from entering the air outlet or return air inlet, reduces the overall area of ​​the drip tray, and allows for a more compact structure for the vehicle air conditioner, facilitating its installation on the vehicle roof.

[0019] 3. The first water receiving tray and the first guide wall are an integral structure, which helps to improve the connection strength between the two. The second water receiving tray and the second guide wall are an integral structure, which helps to improve the connection strength between the two. The third drain hole is located at the top of the water receiving tray. This allows water to be temporarily stored in the water receiving tray and then drained out when the tray is full.

[0020] 4. The connection between the first guide wall and the air outlet is intermittent welding. This shortens the welding speed of welding the first guide wall to the air outlet and facilitates the drainage of water accumulated inside the casing through the intermittent weld seams. The connection between the second guide wall and the return air outlet is also preferably intermittent welding. This shortens the welding speed of welding the second guide wall to the air outlet and facilitates the drainage of water accumulated inside the casing through the intermittent weld seams. A fourth drainage hole is provided on the bottom wall of the casing. The fourth drainage hole allows water inside the casing to pass through and drain outside the casing, further improving the air conditioner's drainage speed.

[0021] 5. The vehicle of the second aspect of this invention, by including or using the vehicle air conditioner of the first aspect of this invention, achieves its effect: the water tray in the vehicle air conditioner of this invention can replace the drain pipe to discharge rainwater, condensate, etc., without the need for connection to the drain pipe. This avoids the large area occupied by the drain pipe, the aging of the interface, and other after-sales problems, such as detachment, which are caused by the installation of the drain pipe. It allows for a more compact structure of the vehicle air conditioner and eliminates the need for maintenance and replacement of the drain pipe, thus improving the user experience. In addition, the water tray in this invention is located below the air outlet and return air inlet. When the water tray is located inside the air conditioner housing, if the water in the water tray is not discharged in time, the water in the water tray may spill into the air outlet or return air inlet when the vehicle body is tilted. However, the water tray in this application is located under the housing, so even if the vehicle body tilts or bumps during driving, the water in the water tray can only be discharged through the third drain hole and will not enter the vehicle through the air outlet or return air inlet.

[0034] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1

[0036] Figure 1 A perspective view of the vehicle air conditioner according to Embodiment 1 of the present invention is shown. Figure 2 The vehicle air conditioner of Embodiment 1 of the present invention in use Figure 1 A cross-sectional view at line AA in the diagram. (See example...) Figure 1 and Figure 2As shown, Embodiment 1 relates to a vehicle air conditioner 100, including a housing 1, a first guide wall 21, a first drain hole 23, a second guide wall 31, a second drain hole 33, a drip tray, and a third drain hole 4. The bottom wall of the housing 1 has an air outlet 11 and an air return outlet 12. The first guide wall 21 surrounds the air outlet 11 and extends towards the interior of the housing 1. The first drain hole 23 is formed on the outer side of the first guide wall 21. The second guide wall 31 surrounds the air return outlet 12 and extends towards the interior of the housing 1. The second drain hole 33 is formed on the outer side of the second guide wall 31. The drip tray is located below the air outlet 11 and the air return outlet 12. A water-receiving cavity is formed on the drip tray. The third drain hole 4 is formed on the drip tray and located close to the housing 1.

[0037] In this embodiment, the vehicle air conditioner 100 has a first guide wall 21, a second guide wall 31, a first drain hole 23, a second drain hole 33, a water collection tray, and a third drain hole 4 added to the housing 1. Water generated during operation of the air conditioner 100 first falls onto the housing 1 and is blocked by the first guide wall 21 when it flows to the air outlet 11. It then flows through the first drain hole 23 formed on the outside of the first guide wall 21 into the water collection tray, where it is stored and discharged through the third drain hole 4. Water flowing to the return air outlet 12 is blocked by the second guide wall 31 and flows through the second drain hole 33 formed on the outside of the second guide wall 31 into the water collection tray, where it is stored and discharged through the third drain hole 4.

[0038] Therefore, the water collection tray in the vehicle air conditioner 100 of this embodiment can replace the drain pipe to discharge rainwater, condensate, etc. This eliminates the need for the water collection tray to be connected to the drain pipe, avoiding the large area occupied and after-sales problems such as interface aging and detachment caused by installing a drain pipe. This allows the structure of the vehicle air conditioner 100 to be more compact, and eliminates the need for maintenance and replacement of the drain pipe, thus improving the user experience. In addition, the water collection tray in this embodiment is located below the air outlet 11 and the return air outlet 12. When the water collection tray is located inside the air conditioner housing, if the water in the water collection tray is not discharged in time, the water in the water collection tray may spill into the air outlet or return air outlet when the vehicle body is tilted. However, in this embodiment, the water collection tray is located under the housing 1, so even if the vehicle body tilts or bumps during driving, the water in the water collection tray can only be discharged outward through the third drain hole 4 and will not enter the vehicle through the air outlet 11 or the return air outlet 12.

[0039] The first guide wall 21 and the second guide wall 31 can be inclined, but are preferably arranged perpendicular to the bottom wall of the housing 1. This prevents water from entering the air outlet 11 or the return air outlet 12 without affecting the airflow of the air outlet 11 or the return air outlet 12. The length of the first guide wall 21 and the second guide wall 31 is preferably in the range of 45-62 mm, and most preferably 48 mm. When the length of the first guide wall 21 and the second guide wall 31 is less than 45 mm, there is still a risk that water will enter the air outlet 11 or the return air outlet 12 when the vehicle body is tilted. When the length of the first guide wall 21 and the second guide wall 31 is greater than 62 mm, it will affect the airflow at the air outlet 11 and the return air outlet 12. The height of the drip tray can be adjusted according to the distance between the housing 1 and the roof, preferably in the range of 8-12 mm, so that the height of the vehicle air conditioner 100 can be adjusted to a suitable range when the drip tray is used for fixed connection with the roof.

[0040] As can be seen from the above technical solution, the vehicle air conditioner 100 of this embodiment adds a first guide wall 21, a second guide wall 31, a first drain hole 23, a second drain hole 33, a water collection tray, and a third drain hole 4 to the housing 1. Water generated during the operation of the air conditioner first falls onto the housing 1. When the water in the housing 1 flows to the air outlet 11, it is blocked by the first guide wall 21 and flows through the first drain hole 23 formed on the outside of the first guide wall 21 into the water collection tray, where it is stored. It is then discharged through the third drain hole 4 on the water collection tray. Water flowing to the return air outlet 12 is blocked by the second guide wall 31 and flows through the second drain hole 33 formed on the outside of the second guide wall 31 into the water collection tray, where it is stored. It is then discharged through the third drain hole 4 on the water collection tray. Therefore, the vehicle air conditioner 100 of the present invention can discharge rainwater and condensate outwards using a water collection tray, avoiding the large area occupied by installing a drain pipe, and after-sales problems such as aging and detachment of the interface. It occupies less space and does not require maintenance or replacement of the drain pipe. At the same time, since the water collection tray is sunken outside the housing 1, even if the vehicle body tilts or bumps during driving, the water in the water collection tray can only be discharged outwards through the third drain hole 4, and will not enter the vehicle through the air outlet 11 or the return air vent 12.

[0041] In this embodiment, the water receiving tray preferably includes a first water receiving tray 2 and a second water receiving tray 3. The first water receiving tray 2 is arranged around the air outlet 11. It can receive water from the first drain hole 23 and discharge it outwards through the third drain hole 4. The second water receiving tray 3 is arranged around the return air outlet 12. It can receive water from the second drain hole 33 and discharge it outwards through the third drain hole 4. When the first water receiving tray 2 and the second water receiving tray 3 are configured as separate units, they can specifically drain water from the air outlet 11 and the return air outlet 12 of the housing 1. This not only prevents water from entering the air outlet 11 or the return air outlet 12 from the housing 1, but also reduces the overall area of ​​the water receiving tray, making the structure of the vehicle air conditioner 100 more compact and easier to install on the roof. The first water receiving tray 2 can be fixedly connected to the first guide wall 21 by welding, bonding, or other methods, but preferably it is an integral structure with the first guide wall 21, which helps to improve the connection strength between the first water receiving tray 2 and the first guide wall 21. The second water receiving tray 3 can be fixedly connected to the second guide wall 31 by welding, bonding, or other methods, but preferably it is an integral structure with the second guide wall 31, which helps to improve the connection strength between the second water receiving tray 3 and the second guide wall 31. Preferably, the third drain hole 4 is located at the edge of the water receiving tray. To avoid poor contact between the air conditioner and the vehicle interior, a sealing gasket is generally provided between the car roof and the air conditioner. The sealing gasket has through holes corresponding to the air outlet 11 and return air inlet 12 of the air conditioner, which can play a sealing role and prevent rainwater and water discharged from the air conditioner from entering the air outlet 11 or return air inlet 12. In this embodiment, the third drain hole 4 is located at the edge of the water receiving tray, which can maximize the distance between the third drain hole 4 and the sealing gasket 203, and prevent the water discharged from the third drain hole 4 from entering between the sealing gasket 203 and the water receiving tray, thereby damaging the sealing performance of the sealing gasket 203. The shape of the air outlet 11 and the return air inlet 12 is preferably, but not limited to, circular, rectangular, or triangular. For example, in this embodiment, both the air outlet 11 and the air return vent 12 are rectangular, which can match the air outlet and air return vent of a car, and facilitates the sealing connection between the first guide wall 21 and the air outlet 11, and the second guide wall 31 and the air return vent 12. Figure 3 and Figure 4As shown, the first guide wall 21 and the first water receiving tray 2 can be either integral or separate. For example, in this embodiment, the first guide wall 21 and the first water receiving tray 2 are integral and are composed of multiple first bent plates 24. Each first bent plate 24 includes a first folded edge 241 and a second folded edge 242 connected to each other. Multiple first folded edges 241 are assembled to form the first water receiving tray 2. Multiple second folded edges 242 are assembled to form the first guide wall 21. Preferably, the multiple first folded edges 241 are connected by welding, preferably by continuous welding, to prevent water from entering the return air vent through the gaps in the first folded edges 241. The second guide wall 31 and the second water receiving tray 3 are integral and are composed of multiple second bent plates 34. Each second bent plate 34 includes a third folded edge 341 and a fourth folded edge 342 connected to each other. Multiple third folded edges 341 are assembled to form the second water receiving tray 3, and multiple second folded edges 242 are assembled to form the first guide wall 21. The preferred connection method for the second fold 242 is welding, preferably continuous welding, to prevent water from entering the return air vent 12 through the gap on the second side.

[0042] Preferably, the end of the first folded edge 241 away from the second folded edge 242 is bent toward the housing 1, forming a first supporting folded edge 243 that abuts against the bottom wall of the housing 1. The first supporting folded edge 243 can support the bottom of the housing 1 and reduce the vibration of the housing 1. The first supporting folded edge 243 is preferably intermittently welded to the housing 1, which allows water in the water receiving tray to drain through the gaps in the welds while ensuring structural strength. Multiple first supporting folded edges 243 are not welded together and form a third drain hole 4. The end of the third folded edge 341 away from the fourth folded edge 342 is bent toward the housing 1, forming a second supporting folded edge 343 that abuts against the bottom wall of the housing 1. The second supporting folded edge 343 can support the bottom of the housing 1 and reduce the vibration of the housing 1. The second supporting folded edge 343 is preferably intermittently welded to the housing 1, which allows water in the water receiving tray to drain through the gaps in the welds while ensuring structural strength. The multiple second support folds 343 are not welded together, and a third water leakage hole 4 is formed between the multiple second support folds 343.

[0043] The connection between the first guide wall 21 and the air outlet 11 can be riveted, bolted, or interference-fitted. Preferably, in this embodiment, the connection between the first guide wall 21 and the air outlet 11 is intermittent welding, which shortens the welding speed of welding the first guide wall 21 and the air outlet 11 together, and facilitates the drainage of water accumulated inside the housing 1 from the intermittent weld seams. The connection between the second guide wall 31 and the return air outlet 12 is preferably intermittent welding, which shortens the welding speed of welding the second guide wall 31 and the air outlet 11 together, and facilitates the drainage of water accumulated inside the housing 1 from the intermittent weld seams. In this embodiment, a fourth drainage hole 5 is provided on the bottom wall of the housing 1. The fourth drainage hole 5 allows water inside the housing 1 to pass through and drain outside the housing 1, further improving the drainage speed of the air conditioner.

[0044] Example 2

[0045] Example 2 relates to a car, such as Figure 2 As shown, the system includes a vehicle body and the vehicle air conditioner 100 provided in Embodiment 1. The vehicle body has a roof 201. A first air vent and a second air vent are provided on the roof 201. The first air vent corresponds to the air outlet 11. The second air vent corresponds to the air return vent 12.

[0046] In this embodiment, the vehicle preferably also includes a sealing gasket 203. The sealing gasket 203 is disposed between the vehicle air conditioner 100 and the vehicle roof 201. The sealing gasket 203 has a through hole in its center. The through hole corresponds to the first air vent or the second air vent. The sealing gasket 203 can seal the vehicle roof 201 with the air outlet and return air vent 12 of the vehicle air conditioner 100, preventing condensate from entering the air outlet 11 or return air vent 12, and at the same time, it acts as a buffer between the vehicle air conditioner 100 and the vehicle roof. Compared with traditional welding and glue sealing, this method can effectively avoid water ingress problems in the later stage, extend the service life of the air conditioner, reduce after-sales problems, and ensure the safety of the air conditioning unit and the comfort of passengers. Preferably, the vehicle air conditioner 100 makes surface contact with the sealing gasket 203 through a water collection tray. This allows the water collection tray to press the sealing gasket 203 tightly, thereby improving the sealing performance of the sealing gasket 203 between the vehicle air conditioner 100 and the vehicle roof, and reducing the vibration of the vehicle air conditioner 100 by utilizing the elasticity of the sealing gasket. Preferably, in this embodiment, the third drain hole 4 is spaced apart from the sealing gasket 203, which can prevent water discharged from the third drain hole 4 from entering between the sealing gasket and the water collection tray, thus preventing damage to the sealing performance of the sealing gasket.

[0047] The sealing gasket 203 is preferably, but not limited to, made of foamed rubber sponge. Preferably, the vehicle also includes a support block 202 disposed between the housing 1 and the roof 201, which supports the weight of the vehicle air conditioner 100. The support block 202 is preferably disposed on a slide rail, allowing it to move relative to the rail. When installation errors occur, the operator can directly move the support block 202 along the slide rail, simplifying the adjustment process. Furthermore, when the support block 202 is made movable, it can be universally compatible and installed on various models of air conditioners.

[0048] In summary, the vehicle air conditioner 100 of Embodiment 1 and the car of Embodiment 2 can drain the water generated during the operation of the air conditioner by means of a water collection tray, avoiding the large area occupied by the installation of a drain pipe, the aging of the interface and the detachment of the drain pipe and other after-sales problems. It occupies less space and does not require maintenance or replacement of the drain pipe.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
