Description

Air conditioner housing, vehicle air conditioning system and motor vehicle Technical Field

[0001] This disclosure relates to an air conditioning housing, a vehicle air conditioning system including the air conditioning housing, and a motor vehicle including the vehicle air conditioning system, and particularly to an air conditioning housing that can block foreign objects and does not affect the discharge of condensate. Background Technology

[0002] Existing vehicle air conditioning systems include a housing and an evaporator housed within the housing. During the heat exchange process between the evaporator and the air, condensate is generated on the outer wall of the evaporator. The condensate flows into the housing below the heat exchanger under the influence of gravity and is discharged through a drain pipe.

[0003] When the working environment of a vehicle's air conditioning system is harsh, foreign objects such as dust and particles may be mixed in. If these foreign objects are not removed in time and accumulate, they may flow with the condensate into the drain pipe and block it, causing poor drainage. At the same time, the high temperature and humidity environment is also prone to the growth of bacteria, producing odors and reducing the user experience.

[0004] Therefore, those skilled in the art are dedicated to developing an air conditioner housing that can prevent foreign objects from clogging the drain pipe and does not affect the discharge of condensate to overcome the above-mentioned defects of the prior art. Summary of the Invention

[0005] The purpose of this disclosure is to provide an air conditioner housing that, by providing a blocking structure upstream of the drain pipe that can block foreign objects without affecting the passage of condensate, effectively prevents foreign objects from clogging the drain pipe, while allowing condensate to drain smoothly, preventing bacterial growth and odor, and improving the user experience. Furthermore, the blocking structure of this disclosure can be configured to include multiple ribs, especially multiple flat ribs, which simplifies the structure, facilitates manufacturing, and saves costs. Moreover, the blocking structure of this disclosure can be integrally molded with the air conditioner housing, which facilitates demolding and avoids problems such as wasted time due to additional assembly of the blocking structure.

[0006] This disclosure provides an air conditioner housing, the air conditioner housing including: a water collection tank for collecting condensate; and a drain pipe for discharging the condensate from the air conditioner housing and disposed at the bottom of the water collection tank, wherein the air conditioner housing further includes a blocking structure for blocking foreign objects, the blocking structure allowing the condensate to pass through and be located upstream of the drain pipe.

[0007] By using the above-mentioned blocking structure, this disclosure can effectively prevent foreign objects from clogging the drain pipe, while also allowing condensate to drain smoothly, preventing the growth of bacteria and the generation of odors, and improving the user experience.

[0008] The air conditioner housing according to this disclosure may also have one or more of the following features, individually or in combination.

[0010] In one or more embodiments, the blocking structure includes a plurality of ribs, wherein the distance between the outermost rib and the wall of the adjacent water collection tank is less than or equal to 3 mm.

[0011] In one or more embodiments, the distance between adjacent ribs in the plurality of ribs is less than or equal to 3 mm.

[0012] In one or more embodiments, the gap between two adjacent ribs is between 1.5 mm and 3 mm.

[0016] In one or more embodiments, at least one end of the rib is provided with a forked structure.

[0017] The present invention, through the above-described arrangement of the ribs, can more effectively stop foreign objects and reduce the risk of drainage pipes being blocked.

[0018] In one or more embodiments, the blocking structure is integrally formed with the air conditioner housing.

[0019] This disclosure, through the aforementioned arrangement of the blocking structure, facilitates demolding and avoids problems such as wasted labor time and installation inconvenience caused by the additional installation of the blocking structure.

[0020] In one or more embodiments, the distance between the blocking structure and the drain pipe is greater than or equal to 5 mm.

[0021] This disclosure, through the aforementioned arrangement of the blocking structure, prevents foreign objects that are blocked from affecting the drainage of the drain pipe.

[0022] In one or more embodiments, a guide plate is further provided in the water collection tank, and the guide plate is located upstream of the blocking structure.

[0023] This disclosure, by setting a baffle plate, can guide condensate to a blocking structure, so that the condensate flows through the blocking structure before flowing to the drain pipe, thus avoiding the problem of condensate flowing directly to the drain pipe and causing foreign objects to clog the drain pipe.

[0030] The following specific embodiments illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification.

[0031] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art in understanding and reading the content disclosed herein, and are not intended to limit the implementation conditions of this disclosure. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effectiveness and purpose of this disclosure, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms such as "above" and "a" used in this specification are merely for clarity of description and are not intended to limit the scope of this disclosure. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this disclosure's implementation.

[0032] This disclosure provides an air conditioner housing. Specific embodiments of this disclosure are described below with reference to the accompanying drawings.

[0033] Figures 1 and 2 show perspective views of the air conditioner housing 1. For clarity, only the lower volute of the air conditioner housing 1 is shown, while other structures such as the upper volute are omitted. As shown in Figures 1 and 2, the air conditioner housing 1, especially its mounting opening H, is mainly used to house a heat exchanger (e.g., an evaporator), so that air can enter the air duct of the air conditioner housing 1 only after passing through this heat exchanger, thus avoiding a series of problems such as air leakage leading to low heat exchange performance and water blowing at the air conditioner outlet. When air passes through the heat exchanger, the water vapor in the air exchanges heat with the cooling medium in the heat exchanger, thereby forming condensate on the outer peripheral wall of the heat exchanger. In order to collect and drain the condensate formed on the outer peripheral wall of the heat exchanger, the air conditioner housing 1 includes a water collection tank 10 located below the mounting opening H (or at the bottom of the heat exchanger) and a drain pipe 20 in fluid communication with the water collection tank 10. The water collection tank 10 is used to collect condensate, and the drain pipe 20 is located at the bottom of the water collection tank 10 and is used to drain the condensate. Condensate forms on the outer wall of the heat exchanger and drips into the water collection tank 10 under the action of gravity, and is discharged from the air conditioner casing 1 through the drain pipe 20.

[0034] When the working environment of the vehicle's air conditioning system is harsh, the condensate in the air conditioning housing 1 may contain foreign objects such as dust and particles. If these foreign objects are not discharged in time and accumulate, they may block the drain pipe 20, causing poor drainage. At the same time, the high temperature and high humidity environment is also prone to the growth of bacteria, producing odors and reducing the user experience.

[0035] To address the aforementioned issues, the air conditioner housing 1 of this disclosure is equipped with a blocking structure 30 that prevents foreign objects from entering without hindering the drainage of condensate, as shown in Figure 2. This blocking structure 30 is located within the water collection tank 10 and upstream of the drain pipe 20. This design ensures that even if dust, particles, or other foreign objects accumulate in the condensate within the air conditioner housing 1, these objects will be blocked by the blocking structure 30 before reaching the drain pipe 20, thus preventing blockage. Furthermore, since the blocking structure 30 does not impede the drainage of condensate (or allows condensate to pass through), the condensate in the water collection tank 20 can drain smoothly, preventing bacterial growth and odor generation, and improving the user experience.

[0036] Specifically, as shown in Figures 1 and 2, the water collection tank 10 located below the installation opening H can be roughly in the shape of a groove with an inclined bottom wall, so that when there is less condensate, the condensate can be collected at the bottom of the water collection tank 10 (i.e., the lower right of the water collection tank 10 as shown in Figure 1), and discharged from the air conditioner housing 1 through the drain pipe 20 provided at the bottom, thus avoiding the problem of condensate easily remaining in the flat-bottomed water collection tank 10, which can easily cause bacteria to grow and produce odors. More specifically, the water collection tank 10 may include a first sidewall 11 and a second sidewall 12 disposed opposite to each other along the air intake direction (referred to as the first direction X) of the air conditioner housing 1, a third sidewall 13 and a fourth sidewall 14 disposed opposite to each other and connected between the first sidewall 11 and the second sidewall 12 along a direction perpendicular to the air intake direction (referred to as the second direction Y), and a bottom wall 15 connecting the first sidewall 11, the second sidewall 12, the third sidewall 13 and the fourth sidewall 14, wherein the bottom wall 15 may deviate from the third sidewall 13 in the second direction Y in a direction away from the mounting opening H until it connects to the fourth sidewall 14, so that the area near the intersection of the bottom wall 15 and the fourth sidewall 14 can serve as the bottom of the water collection tank 10, and the bottom is provided with a drain pipe 20 communicating with the water collection tank 10, so as to drain all the condensate in the water collection tank 10 as much as possible.

[0037] Referring to Figures 2 to 4, the blocking structure 30 is located upstream of the drain pipe 20 and can be installed on at least one of the first side wall 11, the second side wall 12, and the bottom wall 15 of the water collection tank 10. The gap between the outermost edge of the blocking structure 30 and the first side wall 11, the second side wall 12, or the bottom wall 15 (where the blocking structure 30 is not installed, i.e., the distance between them is greater than 0 mm) can be less than or equal to 3 mm. This gap allows for the blocking of accumulated foreign matter without affecting the passage of condensate. The height of the blocking structure 30 is less than the depth of the water collection tank 20, meaning the top of the blocking structure 30 is lower than the opening of the water collection tank 20, preventing the blocking structure 30 from protruding beyond the water collection tank 20 and interfering with the heat exchanger.

[0038] In one embodiment, as shown in Figures 3 and 4, the blocking structure 30 may include three ribs 31, 32, and 33. Rib 31 (also referred to as the first rib 31) may be disposed on the bottom wall 15 and the first side wall 11 of the water collection tank 10, or in other words, rib 31 may be disposed on the bottom wall 15 of the water collection tank 10, with one side, for example, the side away from the fourth side wall 14, directly contacting the first side wall 11. However, this disclosure is not limited to this; for example, a gap of less than or equal to 3 mm may be provided between rib 31 and the first side wall 11, so that this gap can not only stop accumulated foreign matter but also not affect the passage of condensate. The specific position between rib 31 and the first side wall 11 mainly depends on the width of the water collection tank 10 along the first direction X and the dimensions of the blocking structure 30 in the first direction X.

[0039] Rib 32 (also referred to as second rib 32) can be disposed on the bottom wall 15 of the water collection tank 10 and adjacent to rib 31. The two ribs 31 and 32 are not parallel, and the distance between them (i.e., the minimum distance between them) can be less than or equal to 3 mm. Preferably, the distance between the two ribs 31 and 32 can be between 1.5 mm and 3 mm. In this way, the gap between the two ribs 31 and 32 can effectively block the accumulated foreign objects without affecting the passage of condensate. In this embodiment, the distance between the two ribs 31 and 32 can gradually decrease along the second direction Y, that is, the distance between the two ribs 31 and 32 is the smallest near the drain pipe 20. In this way, the two ribs 31 and 32 can not only act as guide plates to guide the condensate to flow towards the drain pipe 20, but the gradually decreasing distance between them can also be used to stop the accumulated foreign objects, so that the foreign objects are stuck between the two ribs 31 and 32.

[0040] Rib 33 (also referred to as third rib 33) can be disposed on the bottom wall 15 of the water collection tank 10, and located between rib 32 and the second side wall 12. Rib 33 is not disposed parallel to rib 32 and / or the second side wall 12, and the distance between the two ribs 32 and 33 (i.e., the minimum distance between them) and the distance between rib 33 and the second side wall 12 (i.e., the minimum distance between them) are both set to be less than or equal to 3mm. Preferably, both of the above distances can be between 1.5mm and 3mm. In this way, the gap between the two ribs 32 and 33, and the gap between rib 33 and the second side wall 12 can effectively block the accumulated foreign matter, and will not affect the passage of condensate. In this embodiment, the distance between the two ribs 32 and 33 can gradually increase along the second direction Y (i.e., the distance between the two ribs 31 and 32 is the smallest at the distance away from the drain pipe 20), and the distance between the rib 33 and the second side wall 12 can gradually decrease along the second direction Y (i.e., the distance between the two is the smallest at the distance close to the drain pipe 20). In this way, the rib 33 can act as a guide plate to guide the condensate water to flow toward the drain pipe 20 and guide the accumulated foreign objects to be stuck between the rib 33 and the second side wall 12. Of course, the gap between the two ribs 32 and 33 can also block foreign objects without affecting the passage of condensate water.

[0041] This disclosure is not limited to the above-mentioned positional relationship between ribs 31, 32, and 33 and between them and the first sidewall 11 and the second sidewall 12. For example, any two ribs or ribs and the first or second sidewall 11, 12 can be arranged in parallel. Alternatively, the distance between the two adjacent ribs can be set to gradually increase or decrease along the second direction Y, as long as the blocking structure 30 can block foreign objects and does not affect the discharge of condensate.

[0042] In one embodiment, as shown in Figures 3 and 4, each rib of the blocking structure 30 can be a flat rib. This design is simple, easy to manufacture, and cost-effective. The blocking structure 30 can be integrally formed with the air conditioner housing 1, for example, by injection molding. Since each rib of the blocking structure 30 is a flat rib, demolding is easy, and the problems of wasted time and inconvenient installation caused by additional installation of the blocking structure 30 can be avoided. Of course, this disclosure is not limited to this. For example, the blocking structure 30 can also be set as other structures, such as a labyrinth structure, a wave-shaped structure, a sieve structure, or any suitable structure, as long as the blocking structure 30 has a gap of less than or equal to 3 mm, and / or the distance between the edge of the blocking structure 30 and the wall of the adjacent water collection tank 10 is less than or equal to 3 mm (or, the distance between the outermost rib of the multiple ribs of the blocking structure 30 and the wall of the adjacent water collection tank 10 is less than or equal to 3 mm), so that it can block foreign objects without affecting the discharge of condensate. Furthermore, the blocking structure 30 is not limited to being integrally formed with the air conditioner housing 1. For example, the blocking structure 30 can also be assembled separately into the water collection tank 10 of the existing air conditioner housing 1 to improve the problem that the drain pipe 20 is easily blocked by foreign objects.

[0043] Please refer to Figure 4. A certain distance D is maintained between the blocking structure 30 and the drain pipe 20. For example, the distance D between the blocking structure 30 and the drain pipe 20 (i.e., the vertical distance between the edge of the blocking structure 30 near the drain pipe 20 and the opening edge of the drain pipe 20) can be set to greater than or equal to 5 mm. Preferably, the distance D between the two can be set between 15-25 mm. More preferably, the distance D between the two can be set to approximately 20 mm. This arrangement ensures that foreign objects blocked by the blocking structure 30 will not affect the drainage of the drain pipe 20, and that condensate dripping from the outer peripheral wall of the heat exchanger can, as far as possible, flow through the blocking structure 30 before reaching the drain pipe 20 and being discharged. If the distance between the two is too small, the foreign objects blocked by the obstruction structure 30 may cause the drain pipe 20 to drain poorly; if the distance between the two is too large, a lot of condensate on the outer wall of the heat exchanger may drip directly downstream of the obstruction structure 30, that is, the dripping condensate does not flow through the obstruction structure 30, but flows directly to the drain pipe 20. In this way, the foreign objects accumulated in the condensate may block the drain pipe 20, causing poor drainage and making it easy for bacteria to grow and produce odors.

[0044] Please refer back to Figure 2. Multiple guide plates 40 may also be provided within the water collection tank 10 (this disclosure uses four as an example, but is not limited to this). The guide plates 40 can be positioned upstream of the blocking structure 30 to guide the condensate dripping into the water collection tank 10 to the blocking structure 30, allowing the condensate to flow through the blocking structure 30 before flowing to the drain pipe 20. In one embodiment, the guide plate 40 may be a generally flat guide plate and may be integrally formed with the air conditioner housing 1 to simplify its structure, facilitate manufacturing (or demolding), and reduce costs. In this embodiment, the guide plates 40 are generally positioned on the side of the blocking structure 30 opposite to the second direction Y (i.e., on the left side of the blocking structure 30 shown in Figure 2) and extend generally toward the blocking structure 30 to guide the condensate to the blocking structure 30. However, this disclosure is not limited to this. For example, when the distance between the blocking structure 30 and the drain pipe 20 is far, one or more of the guide plates 40 may also be at least partially disposed on one side of the blocking structure 30 along the second direction Y (i.e., at least partially disposed on the right side of the blocking structure 30 shown in FIG. 2) and extend generally upstream of the blocking structure 30 (to the left side shown in FIG. 2) to avoid the problem of condensate flowing directly to the drain pipe 20 without flowing through the blocking structure 30, thus causing blockage of the drain pipe 20.

[0045] In a modified embodiment (not shown), at least one end of each rib 31, 32, 33 of the blocking structure 30 may be provided with a forked structure, which may be generally in the shape of a comb and extend from each rib 31, 32, 33 toward a direction away from it. In this way, the forked structure can further effectively block foreign objects in the condensate water and further reduce the possibility of clogging the drain pipe 20.

[0046] Although the above embodiments of this disclosure are mainly described with the blocking structure 30 including three ribs 31, 32, 33, this disclosure is not limited thereto. For example, the blocking structure 30 may also include only one, two, four or more ribs, which mainly depends on the width of the water collection tank 10 along the first direction X.

[0047] The above embodiments of this disclosure are mainly illustrated by taking the example of the blocking structure 30 being disposed on the bottom wall 15 of the water collection tank 20 (of course, the blocking structure 30 may also contact the first side wall 11 and / or the second side wall 12). However, this disclosure is not limited to this. For example, the blocking structure 30 may also be directly disposed on the first side wall 11 and the second side wall 12, with a gap of less than or equal to 3 mm between it and the bottom wall 15. As long as the distance between the outermost edge of the blocking structure 30 and the wall of the adjacent water collection tank 10 is less than or equal to 3 mm, it can block foreign objects and does not affect the passage of condensate.

[0048] The above embodiments of this disclosure are mainly illustrated by the example of the blocking structure 30 including multiple ribs, especially flat ribs. However, this disclosure is not limited to this. For example, the blocking structure 30 may also include bent ribs or other components of any shape, as long as the blocking structure 30 can block foreign objects and does not affect the passage of condensate.

[0049] Furthermore, the above embodiments of this disclosure are mainly illustrated by the example of a blocking structure 30 and a guide plate 40 provided in the water collection tank 10. However, this disclosure is not limited to this. For example, the blocking structure 30 can also be integrated on a portion of the guide plate 40 near the drain pipe 20, as long as it can block foreign objects and does not affect the discharge of condensate.

[0050] In summary, this disclosure provides an air conditioner housing that, by providing a blocking structure upstream of the drain pipe that can block foreign objects without affecting the passage of condensate, effectively prevents foreign objects from clogging the drain pipe, while also allowing condensate to drain smoothly, preventing bacterial growth and odor, and improving the user experience. Furthermore, the blocking structure of this disclosure can be configured to include multiple ribs, especially multiple flat ribs, which simplifies the structure, facilitates manufacturing, and saves costs. Moreover, the blocking structure of this disclosure can be integrally molded with the air conditioner housing, which facilitates demolding and avoids problems such as wasted labor time due to additional assembly of the blocking structure.

[0051] This disclosure also provides a vehicle air conditioning system, which may include the aforementioned air conditioning housing 1 and a heat exchanger disposed within the air conditioning housing 1, particularly at its mounting opening H. When air passes through the heat exchanger and exchanges heat with it, condensation forms on the outer peripheral wall of the heat exchanger. Under the action of gravity, the condensation drips into the water collection tank 10 and flows to the blocking structure 30 under the guidance of the baffle plate 40. The blocking structure 30 stops foreign objects in the condensation, and the condensation continues to flow to the drain pipe 20 and is discharged from the air conditioning housing 1, avoiding problems such as poor drainage caused by foreign objects clogging the drain pipe 20.

[0052] Additionally, this disclosure also provides a motor vehicle, which may include the aforementioned vehicle air conditioning system.

[0053] The foregoing description, with reference to preferred embodiments, illustrates exemplary implementations of the air conditioning housing, vehicle air conditioning system, and motor vehicle provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
