Abstract
Description
Technical Field

[0002] In automotive air conditioning systems, drainage management of the air conditioning unit is a crucial aspect of ensuring overall vehicle comfort and safety. Condensate generated during air conditioning operation must be drained promptly to prevent water accumulation and its adverse effects on the vehicle's interior environment and components.
[0003] In existing technology, when condensate enters the distribution box area of the heater core, the condensate in this area cannot be discharged in time. This not only causes the condensate to seep into the sponge or plastic parts, leading to mold and odor over time, attracting mosquitoes and other insects, thus affecting the driving experience; but the accumulated condensate may even drip into the electrical components inside the air conditioning unit, causing the components to malfunction and resulting in a safety accident.
[0004] Therefore, there is an urgent need to design a diversion and drainage automotive air conditioner to solve the above technical problems. Utility Model Content

[0010] The inner wall of the first housing is provided with a flow guide groove, and the second housing is provided with a flow guide hole and a drain hole. One end of the flow guide groove is connected to the bottom area of the warm air core, and the other end of the flow guide groove is connected to the flow guide hole. The flow guide hole is connected to the drain hole. Along the first direction, the height of the drain hole is lower than the height of the flow guide hole.
[0011] As an optional technical solution for a deflector-drainage automotive air conditioner, the deflector groove has a first end and a second end. The first end is connected to the bottom region of the heater core, and the second end is connected to the deflector hole. Along the first direction, the height of the second end is lower than the height of the first end.
[0012] As an optional technical solution for a water-guiding and drainage automotive air conditioner, the bottom of the guide channel is provided with a number of guide ribs, which are distributed at intervals along the water flow direction, and the height of the guide ribs gradually decreases from the first end to the second end, so as to guide the water flow to the guide hole.
[0013] As an optional technical solution for a drainage-guided automotive air conditioner, the drainage channels are configured as multiple channels, and the multiple drainage channels are distributed at equal intervals on the inner wall of the first housing.
[0014] As an optional technical solution for a deflector-drainage automotive air conditioning system, a water-blocking edge is provided around the bottom area of the heater core, and the height of the water-blocking edge is higher than the bottom height of the deflector channel.
[0015] As an optional technical solution for a drainage-guided automotive air conditioner, the diameter of the guide hole is larger than the width of the guide groove.
[0016] As an optional technical solution for a car air conditioner with drainage, the edge of the drainage hole is provided with a downwardly extending water guide flange, which extends into the drainage hole of the second housing.

[0019] As an optional technical solution for a car air conditioning system that guides and drains water, the drain pipe is made of rubber, and both the first housing and the second housing are made of engineering plastics.
[0020] The beneficial effects of this utility model include at least the following:
[0021] This utility model provides a deflector-drainage automotive air conditioner, which includes a distribution box, an evaporator, a heater core, an evaporator, a deflector channel, a deflector hole, and a drain hole. The distribution box includes a first housing and a heater core, with the heater core disposed within the first housing. The evaporator includes a second housing and an evaporator, with the evaporator disposed within the second housing. A deflector channel is provided on the inner wall of the first housing, and a deflector hole and a drain hole are provided on the second housing. One end of the deflector channel communicates with the bottom area of the heater core, and the other end of the deflector channel communicates with the deflector hole, which in turn communicates with the drain hole.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0036] This embodiment provides a diversion and drainage automotive air conditioner that can promptly drain accumulated water from the distribution box, improving the driving experience and reducing safety hazards.
[0037] like Figures 1-3 As shown, the deflector-drainage automotive air conditioner mainly includes a distribution box 10, an evaporator 20, a heater core 12, an evaporator 22, a deflector channel 13, a deflector hole 23, and a drain hole 24. The distribution box 10 includes a first housing 11 and a heater core 12, with the heater core 12 disposed within the first housing 11. The evaporator 20 includes a second housing 21 and an evaporator 22, with the evaporator 22 disposed within the second housing 21. A deflector channel 13 is provided on the inner wall of the first housing 11, and a deflector hole 23 and a drain hole 24 are provided on the wall of the second housing 21. One end of the deflector channel 13 communicates with the bottom area of the heater core 12, and the other end of the deflector channel 13 communicates with the deflector hole 23. The deflector hole 23 communicates with the drain hole 24. Along the first direction (… Figure 2 (in the X-axis direction), the height of the drain hole 24 is lower than the height of the guide hole 23.
[0038] Based on the above design, this embodiment provides a guide channel 13 within the first housing 11 of the distribution box 10, which connects to the guide hole 23 and drain hole 24 on the second housing 21 of the evaporator box 20, forming a complete drainage path. This allows for timely drainage of water accumulated in the bottom area of the heater core 12 within the distribution box 10, effectively preventing water accumulation and reducing problems such as mold, odor, and insect attraction caused by condensate (water) seeping into sponges or plastic parts, thus improving the driving experience. It also avoids the risk of water dripping into electrical components within the air conditioning unit, reducing safety hazards. Furthermore, along the first direction, the height of the drain hole 24 is lower than the height of the guide hole 23. Utilizing gravity, this facilitates water flow towards the drain hole 24, ensuring smooth drainage and improving drainage efficiency.
[0039] It should be noted that, Figure 3 The direction of the arrow in the diagram indicates the drainage path.
[0040] It is understood that the condensate produced by the evaporator 22 in this embodiment accumulates at the bottom of the evaporator 22 and then flows directly to the drain hole 24 of the second housing 21 and is discharged.
[0041] Optionally, in this embodiment, the flow guide trough 13 is integrally injection molded onto the inner wall of the first housing 11. Furthermore, the cross-section of the flow guide trough 13 can be U-shaped or V-shaped.
[0042] Optionally, in this embodiment, multiple guide channels 13 are provided, and the multiple guide channels 13 are distributed at equal intervals on the inner wall of the first housing 11, thereby increasing the drainage area and allowing the water in the bottom area of the warm air core 12 to flow more evenly into each guide channel 13, improving the drainage capacity of the bottom area of the entire distribution box 10, effectively preventing the occurrence of local water accumulation, and further improving the drainage effect.
[0043] For example, the number of guide channels 13 is set to 2-4, and the spacing between two adjacent guide channels 13 is set according to the size of the warm air core 12. For example, the spacing can be set to 100mm-150mm, and the width of the guide channel 13 is set to 5mm-8mm.
[0044] In this embodiment, the first housing 11 is provided with a first snap-fit part 14, and the second housing 21 is provided with a second snap-fit part 25. The first snap-fit part 14 and the second snap-fit part 25 are snap-fitted together. This makes the connection between the distribution box 10 and the evaporator box 20 more convenient and secure, facilitates the assembly and disassembly of the drainage-guided automotive air conditioner, and is beneficial for cleaning, maintaining and repairing the drainage structure inside the drainage-guided automotive air conditioner. At the same time, it also ensures the stability and reliability of the drainage.
[0045] For example, the first snap-fit portion 14 on the first housing 11 is a snap-fit, and the second snap-fit portion 25 on the second housing 21 is a slot. There are three sets of snap-fit and slots, which are distributed on both sides and the top of the first housing 11 and the second housing 21, respectively. The matching dimensions of the snap-fit and the slot are precise, and the elasticity of the snap-fit is moderate, which can ensure a tight connection between the distribution box 10 and the evaporator box 20, while facilitating disassembly and installation, and ensuring the integrity and sealing of the drainage automotive air conditioner.
[0046] Alternatively, in some embodiments, the first housing 11 and the second housing 21 may also be detachably connected using components such as bolts.
[0047] like Figures 2-3As shown, the guide channel 13 in this embodiment has a first end 131 and a second end 132. The first end 131 is connected to the bottom area of the heater core 12, and the second end 132 is connected to the guide hole 23. Along the first direction, the height of the second end 132 is lower than the height of the first end 131, thereby realizing the inclined setting of the guide channel 13. This allows the guide channel 13 to use gravity to make the water flow naturally towards the second end 132, further improving the drainage efficiency of the guide channel 13 and ensuring that the accumulated water can quickly flow from the bottom area of the heater core 12 to the guide hole 23, thus enhancing the smoothness of drainage.
[0048] For example, the tilt angle of the guide channel 13 is set to 10°-30°.
[0049] In some optional embodiments, the bottom of the guide channel 13 is provided with a number of guide ribs, which are distributed at intervals along the water flow direction, and the height of the guide ribs gradually decreases from the first end 131 to the second end 132, so as to guide the water flow to the guide hole 23 in a concentrated manner, avoid the water flow from being dispersed or turbulent in the guide channel 13, improve the orderliness and efficiency of drainage, and also enhance the flow velocity of the water flow, so that the accumulated water can be discharged more quickly.
[0050] For example, the width of the drainage ribs is set to 1mm-3mm, the height of the drainage ribs gradually decreases from 4mm-6mm at the first end 131 to 1mm-3mm at the second end 132, the spacing between adjacent drainage ribs is 2mm-8mm, and they are integrally molded from engineering plastic material. The drainage ribs are uniformly distributed at the bottom of the guide channel 13 by injection molding to ensure that the water flow can flow stably along the direction guided by the drainage ribs and improve drainage efficiency.
[0051] In some alternative embodiments, a water-blocking edge is provided around the bottom area of the heater core 12. The height of the water-blocking edge is higher than the bottom height of the guide channel 13, which can effectively prevent water from spreading to the surrounding area of the heater core 12 and prevent water from seeping into other areas (such as the electrical component area), thus protecting the electrical components. At the same time, it confines the water near the guide channel 13, ensuring that the water can smoothly enter the guide channel 13 and be discharged.
[0052] For example, the height of the water-blocking edge can be set to 5mm-10mm, and it is integrally molded from engineering plastic material. It surrounds the edge of the bottom area of the heater core 12 to form a water-blocking barrier and prevent water from overflowing from the edge of the heater core 12 to other areas.
[0053] In some optional embodiments, the diameter of the guide hole 23 is larger than the width of the guide channel 13, so that the water flow in the guide channel 13 can flow smoothly and completely into the guide hole 23, avoiding water flow obstruction or partial water overflow from the guide channel 13 due to the small diameter, thus ensuring the continuity and integrity of drainage and improving the reliability of drainage.
[0054] For example, the diameter of the guide hole 23 can be set to 18mm-22mm, and the width of the guide groove 13 can be set to 12mm-16mm.
[0055] In some optional embodiments, the edge of the guide hole 23 is provided with a downwardly extending water-guiding flange that extends into the drain hole 24 of the second housing 21. This further guides the water flow accurately into the drain hole 24, preventing water from overflowing or splashing at the connection between the guide hole 23 and the drain hole 24, ensuring that the water flows steadily to the drain hole 24 for discharge, and improving the accuracy and efficiency of drainage.
[0056] like Figures 1-2 As shown, the drainage-type automotive air conditioner in this embodiment also includes a drain pipe 30. One end of the drain pipe 30 is interference-fitted with the drain hole 24, and the other end of the drain pipe 30 extends to the outside of the vehicle compartment. This ensures the sealing and connection strength between the drain pipe 30 and the drain hole 24, preventing water leakage or detachment of the drain pipe 30 during drainage. Simultaneously, it directly drains accumulated water outside the vehicle compartment, preventing water accumulation inside the compartment, further improving the interior environment of the vehicle and reducing safety hazards.
[0057] Optionally, in this embodiment, the drain pipe 30 is made of rubber, which has good flexibility and sealing properties, and can effectively adapt to vibrations and temperature changes during vehicle operation, ensuring drainage stability. The first housing 11 and the second housing 21 are both engineering plastic parts, which have high strength and corrosion resistance, can protect the internal drainage structure, and at the same time reduce the weight of the drainage vehicle air conditioner, improving the vehicle's energy efficiency.
[0058] For example, the drain pipe 30 may be made of EPDM rubber, and the first housing 11 and the second housing 21 may be made of reinforced nylon engineering plastic.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
