Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning equipment technology, and in particular to an automotive air conditioning drainage device. Background Technology

[0002] When the car's air conditioning system is in cooling mode, the temperature of the evaporator core inside the air conditioner is low. When hot and humid air passes through, the water vapor in the air will condense and form water droplets. Therefore, the air conditioner needs to be equipped with a drain pipe to drain the condensate outside the car.

[0003] For example, CN115107462A, published on September 27, 2022, discloses an automotive air conditioning drain pipe. It includes a first drain pipe and a second drain pipe; one end of the first drain pipe is connected to the air conditioner assembly, and the other end is connected to one end of the second drain pipe; the other end of the second drain pipe is connected to the vehicle body. The aforementioned automotive air conditioning drain structure suffers from excessive condensate discharge from the lower evaporator housing, leading to abnormal noise during drainage, excessive noise during air conditioning operation, and poor practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a car air conditioning drainage device with lower noise. This invention, through a water-resistant baffle installed inside the lower housing, effectively prevents excessive condensate from instantly filling the drain outlet, creating eddies that could cause abnormal noise from the car air conditioning system, thus reducing operating noise and improving practicality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: an automotive air conditioning drainage device, including a lower housing disposed on the automotive air conditioning evaporator, a drain pipe disposed on the lower housing, and a water-proof baffle rib disposed inside the lower housing.

[0006] The lower housing is provided with a connecting pipe, which is connected to a drain pipe.

[0007] The water-proof baffle is installed at the connection between the lower shell and the connecting pipe.

[0008] The water-proof baffle has a rounded corner on the side facing the lower shell.

[0009] The drain pipe is equipped with a corrugated pipe.

[0010] The drain pipe is equipped with a snap-fit ​​sleeve, which snaps into the connecting pipe.

[0011] The snap-fit ​​cylinder is provided with a limiting platform, which abuts against the lower housing.

[0012] The connecting pipe has a protrusion, and the snap-fit ​​cylinder has a connecting groove that connects to the protrusion.

[0013] The beneficial effects of this utility model are: The water-proof baffles installed in the lower housing can effectively prevent the drain outlet from being filled instantly when the condensate water output is too large, thus avoiding the formation of eddies that cause abnormal noise from the car air conditioner, reducing the operating noise of the air conditioner and making it more practical. The drain pipe is equipped with a corrugated pipe, which allows for easy adjustment of the drain pipe's angle, thus enabling adjustment of the drain pipe's arrangement in the car and making the drain pipe more practical. The drain pipe is easily installed by connecting the connecting pipe on the lower shell and the clamping sleeve on the drain pipe, which facilitates maintenance and replacement. The clamping sleeve has a groove with a clamp inside. The clamp inside the groove ensures a stable connection between the clamping sleeve and the connecting pipe, preventing the drain pipe from falling off the lower shell and ensuring stable installation of the drain pipe.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] like Figure 1As shown, the automotive air conditioning drainage device includes a lower housing 2 installed on the automotive air conditioning evaporator 1, a drain pipe 3 installed on the lower housing 2, and a water-proof baffle 4 installed inside the lower housing 2. Specifically, the lower housing 2 is wedge-shaped, and the cross-sectional area of ​​the upper side of the lower housing 2 is larger than that of the upper side. The drain pipe 3 is located at the bottom of the lower housing 2.

[0022] When in use, the condensate produced by the evaporator 1 falls into the lower housing 2 due to gravity and is discharged through the drain pipe 3 connected to the lower housing 2. The water-proof baffle 4 set in the lower housing 2 can effectively prevent the drain outlet from being filled instantly when the condensate output is too large, thus avoiding the formation of eddies that cause abnormal noise from the car air conditioner, reducing the noise of the air conditioner and making it more practical.

[0023] Specifically, the lower housing 2 is provided with a connecting pipe 5, which is connected to the drain pipe 3. The connection between the lower housing 2 and the drain pipe 3 is achieved through the setting of the connecting pipe 5, thereby ensuring that the condensate can be stably discharged from the lower housing 2. Specifically, the connecting pipe 5 is integrally formed with the lower housing 2, and the connecting pipe 5 is located at the bottom of the lower housing 2.

[0024] Reference Figure 3 The water-proof baffle 4 is installed at the connection between the lower shell 2 and the connecting pipe 5. By installing the water-proof baffle 4 inside the connecting pipe 5, it can block the condensate accumulated in the lower shell 2, ensuring that the condensate is stably discharged from the connecting pipe 5 into the drain pipe 3, thus realizing the drainage work. Specifically, the water-proof baffle 4 and the connecting pipe 5 are integrally formed.

[0025] The water-proof baffle 4 has a rounded corner 401 on the side facing the lower housing 2. The rounded corner 401 enables the water-proof baffle 4 to stably buffer and separate the water flow, ensuring smooth water flow and preventing abnormal noise.

[0026] The drain pipe 3 is equipped with a corrugated pipe 6. The corrugated pipe 6 allows for easy adjustment of the angle of the drain pipe 3, thereby enabling adjustment of the arrangement of the drain pipe 3 in the car and making the drain pipe 3 more practical.

[0027] The drain pipe 3 is equipped with a clamping sleeve 7, which clamps into the connecting pipe 5. The interference fit between the clamping sleeve 7 and the connecting pipe 5 facilitates the convenient installation of the drain pipe 3 and makes it easier to maintain and replace it. Specifically, the connecting pipe 5 is located inside the clamping sleeve 7, thereby ensuring a stable connection of the drain pipe 3 to the lower housing 1. The snap-fit ​​cylinder 7 is provided with a limiting platform 8, which abuts against the lower housing 2. After the snap-fit ​​cylinder 7 is snapped into the connecting pipe 5, the limiting platform 8 contacts the lower housing 2, thereby realizing the installation of the snap-fit ​​cylinder 7 in place, thus ensuring the stable installation of the drain pipe 3 on the lower housing 2.

[0028] The connecting pipe 5 is provided with a protrusion 9, and the snap-fit ​​cylinder 7 is provided with a connecting groove 10 that connects to the protrusion 9. After the snap-fit ​​cylinder 7 is snapped into the connecting pipe 5, the protrusion 9 extends into the connecting groove 10, which further increases the connection stability between the snap-fit ​​cylinder 7 and the connecting pipe 5, thereby preventing the drain pipe 3 from falling off the lower housing 2.

[0029] In summary, the condensate produced by the evaporator 1 falls into the lower housing 2 due to gravity and is discharged through the drain pipe 3 connected to the lower housing 2. The water-proof baffle 4 set in the lower housing 2 can effectively prevent the drain outlet from being filled instantly when the condensate output is too large, thus avoiding the formation of eddies that cause abnormal noise from the car air conditioner, reducing the noise of the air conditioner and making it more practical. The drain pipe 3 is equipped with a corrugated pipe 6. The corrugated pipe 6 allows for easy adjustment of the angle of the drain pipe 3, thereby enabling adjustment of the arrangement of the drain pipe 3 in the car and making the drain pipe 3 more practical. The connection between the connecting pipe 5 on the lower housing 2 and the snap-fit ​​cylinder 7 on the drain pipe 3 facilitates the convenient installation of the drain pipe 3 and makes it easier to maintain and replace it. The snap-fit ​​cylinder 7 has a groove 8 and a clamp 9 in the groove 8. The clamp 9 in the groove 8 achieves a stable connection between the snap-fit ​​cylinder 7 and the connecting pipe 5, preventing the drain pipe 3 from falling off the lower housing 2 and ensuring the stable installation of the drain pipe 3.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
