Description

Technical Field

[0001] This invention belongs to the field of automotive parts, specifically relating to a drainage groove structure for the lower housing of an automotive air conditioning assembly. Background Technology

[0002] The automotive air conditioning system, or HVAC for short, is used to regulate the temperature, humidity, and air cleanliness inside the vehicle and to create air circulation, which has a significant impact on the overall comfort of the vehicle.

[0003] With the development of automotive air conditioning technology, there are many types of HVAC assembly structures. Built-in automotive air conditioners are usually located under the dashboard, which takes up some space in the driver and passenger seats. Taking the NIO Pegasus model as an example, due to the limitation of the overall vehicle space, the blower and drain outlet are generally located on the same side, and the filter is located between the evaporator and the drain outlet.

[0004] Therefore, when the evaporator is tilted forward or operating horizontally, a small amount of condensate will drip onto the windward side, causing the filter element to become damp, posing a potential odor hazard, affecting the driving experience of the passengers, and the air blown out by the blower will also obstruct the discharge of condensate to the drain outlet. Summary of the Invention

[0005] The purpose of this invention is to provide a drainage groove structure for the lower housing of an automotive air conditioning assembly in order to solve the above-mentioned problems.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A drainage channel structure for the lower housing of an automotive air conditioning assembly, comprising:

[0008] The main tank is located in the middle of the lower housing and is connected to the drain outlet on the front side;

[0009] The core support structure is located at the bottom of the main tank. The core support structure is used to support the evaporator and block the windward side air intake.

[0010] And a hydrophilic structure disposed on the front side of the core support structure, the front and rear sides of the hydrophilic structure extending to the bottom of the filter element and the evaporator respectively, for guiding the condensate at the bottom of the filter element and the evaporator to the drain outlet;

[0011] The core support structure includes two rows of staggered V-shaped plates, with the V-shaped openings of the V-shaped plates facing the hydrophilic structure, and a drainage channel is formed between two adjacent V-shaped plates in each row.

[0012] As a further optimization of the present invention, the main tank body is inclined downward from the rear to the front, and inclined downward from the left and right sides to the middle, and the drain outlet is connected to the bottom of the tank body at the middle of the front end of the main tank body.

[0013] As a further optimization of the present invention, a pad is provided on the lower surface of the hydrophilic structure, the pad is fixedly connected to the main tank, and a drainage gap is left between the hydrophilic structure and the main tank.

[0014] As a further optimization of the present invention, the upper surface of the hydrophilic structure is inclined downward from the front to the rear.

[0015] As a further optimization of the present invention, the hydrophilic structure is made of a hydrophilic foam porous medium, wherein the hydrophilic foam porous medium is a foam porous medium made of chromium, aluminum or zinc materials.

[0016] As a further optimization of the present invention, the upper and lower halves of the hydrophilic structure are respectively provided with a plurality of upper air guide holes and lower air guide holes, the upper air guide holes and lower air guide holes are connected, the upper air guide holes are inclined downward from the front side to the rear side, and the lower air guide holes are inclined downward from the rear side to the front side.

[0017] As a further optimization of the present invention, evaporator bracket mounting slots and filter element mounting slots are arranged side by side on both the left and right sides of the main tank, and the evaporator bracket mounting slots and the main tank are connected through side tanks.

[0018] As a further optimization of the present invention, the side groove body is connected to the evaporator bracket mounting groove through an opening, the side groove body is inclined downward from the front end to the rear end and the rear end is provided with a groove that communicates with the main groove body.

[0019] As a further optimization of the present invention, a row of baffles is provided inside the side tank from the front to the rear. The baffles are inclined from the front to the rear and a drainage gap is left between the rear end of the baffles and the side tank.

[0020] The beneficial effects of this invention are as follows:

[0021] 1) By setting a core support structure at the bottom of the evaporator core, the present invention can not only support the overhead evaporator and ensure smooth drainage of condensate on its surface, but also block the air intake on the windward side, so that the condensate on the evaporator surface is discharged against the wind in a one-way direction to the drain outlet, and the drainage is not affected by the air intake, thus solving the problem of air intake affecting drainage caused by the blower and the drain outlet being set on the same side.

[0022] 2) By setting side tanks on both sides of the main tank, the present invention can divert the condensate dripping on the filter element to the main tank, and then discharge it to the drain outlet through the core support structure, thus solving the problem of the filter element being damp and having a long-term odor hazard caused by condensate dripping on the filter element.

[0023] 3) This invention solves the problems of condensate adhering to the filter element and being difficult to drip out, as well as condensate splashing at the bottom and wetting the filter element by setting a hydrophilic structure at the bottom of the evaporator and filter element.

[0024] 4) The present invention has several upper and lower air guide holes with opposite inclination directions in the upper and lower parts of the hydrophilic structure, so that the air is blown out at an angle from the evaporator side to the filter element side. On the one hand, it can quickly blow out the condensate from the core support structure to the drain outlet. On the other hand, it can use the air intake to quickly carry out the condensate adsorbed by the hydrophilic structure, ensuring the continuous water absorption performance of the hydrophilic structure.

It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

Therefore, they should not be construed as limitations on this invention. In the description of this invention, unless otherwise stated, "a plurality of" or "several" means two or more.

[0033] Example 1

[0034] like Figure 1-4 As shown, a drainage channel structure for the lower housing of an automotive air conditioning assembly includes a main channel 1 disposed in the middle of the lower housing 100 and communicating with a drain outlet 110 on the front side, a core support structure 2 disposed at the bottom of the main channel 1, and a hydrophilic structure 3 disposed on the front side of the core support structure 2; wherein,

[0035] The main tank 1 slopes downward from the rear to the front and from the left and right sides to the middle. The drain outlet 110 is connected to the bottom of the tank at the middle of the front end of the main tank 1, which can collect condensate and discharge it from the drain outlet 110.

[0036] The core support structure 2 is integrally formed with the lower shell 100. The core support structure 2 is used to support the evaporator and block the windward side air intake. The core support structure 2 includes two rows of staggered V-shaped plates 21. The V-shaped opening of the V-shaped plate 21 faces the hydrophilic structure 3, and a drainage channel 22 is formed between two adjacent V-shaped plates 21 in each row. The bottom of the pointed end of the V-shaped plate 21 on the front side corresponds to the gap between the two V-shaped plates 21 on the rear side.

[0037] The hydrophilic structure 3 extends to the bottom of the filter element and the evaporator on both the front and rear sides, respectively, to guide the condensate at the bottom of the filter element and the evaporator to the drain outlet 110; a pad 4 is provided on the lower surface of the hydrophilic structure 3, and the pad 4 is fixedly connected to the main tank 1, that is, integrally formed with the lower shell 100. A drainage gap is left between the hydrophilic structure 3 and the main tank 1. The upper surface of the hydrophilic structure 3 is inclined downward from the front to the rear. The hydrophilic structure 3 is made of hydrophilic foam porous medium. The hydrophilic foam porous medium is a foam porous medium made of chromium, aluminum or zinc materials, and the pore diameter of the foam porous medium is 1-400 micrometers, the porosity is 50%-80%, and it has high water absorption.

[0038] It should be noted that since the blower and the drain outlet 110 are located on the same side, when the blower is working, its air intake direction is opposite to the condensate drain direction, which will affect the drainage and cause the condensate to splash. Therefore, we use the core support structure 2 to support the evaporator core and block the air intake at the bottom of the evaporator on the windward side, so as to ensure that the condensate flowing down the evaporator surface can be discharged from the drain channel 22 of the core support structure 2 to the drain outlet 110 on the front side.

[0039] In addition, the staggered distribution of the two rows of V-shaped plates 21 and the orientation of their V-shaped openings ensure that the condensate discharged to the front of the core support structure 2 will not flow back, thus achieving one-way drainage.

[0040] Finally, by setting a hydrophilic structure 3 at the bottom of the evaporator and the filter element, the hydrophilic structure 3 can quickly adsorb and guide the condensate at the bottom of the filter element and the bottom of the evaporator to the main tank 1 at the bottom, and finally discharge it from the drain outlet 110.

[0041] The hydrophilic structure 3 allows for easy removal and replacement of the filter cartridge, making it convenient to use.

[0042] like Figure 4-5 As shown, the upper and lower halves of the hydrophilic structure 3 are respectively provided with a plurality of upper air guide holes 5 and lower air guide holes 6. The upper air guide holes 5 and lower air guide holes 6 are connected. The upper air guide holes 5 are inclined downward from the front to the rear, and the lower air guide holes 6 are inclined downward from the rear to the front.

[0043] It should be noted that after the blower's air enters through the filter element, some of the air can enter below the hydrophilic structure 3 through the upper air guide hole 5 and the lower air guide hole 6. During this process, the air first enters the hydrophilic structure 3 through the upper air guide hole 5, then enters the lower air guide hole 6 in the opposite direction, and finally the air is blown out from the rear to the front, that is, blown out from the evaporator side to the filter element side. This can quickly blow out the condensate from the core support structure 2 to the drain outlet 110. Moreover, the air entering the hydrophilic structure 3 through the air guide hole can also quickly carry out the condensate adsorbed by the hydrophilic structure 3, ensuring the continuous water absorption performance of the hydrophilic structure 3, that is, drying the hydrophilic structure 3.

[0044] like Figure 1-3 As shown, evaporator bracket mounting slots 120 and filter element mounting slots 130 are arranged side by side on both the left and right sides of the main tank 1, and the evaporator bracket mounting slots 120 and the main tank 1 are connected by side tanks 7.

[0045] The side tank 7 is connected to the evaporator bracket mounting groove 120 through an opening 71. The side tank 7 is inclined downward from the front end to the rear end and the rear end is provided with a groove 72 that communicates with the main tank 1.

[0046] A row of baffles 8 is provided inside the side channel 7 from the front to the rear. The baffles 8 are inclined from the front to the rear and a drainage gap is left between the rear end of the baffles 8 and the side channel 7. The baffles 8 are integrally formed with the lower shell 100.

[0047] It should be noted that when the evaporator is tilted forward or horizontally, a small amount of condensate will drip on the windward side, causing the filter element to become damp and posing a risk of odor. Therefore, we have set up side tanks 7 on both sides of the main tank 1. The condensate dripping from both sides of the filter element can enter the main tank 1 from the side tanks 7 and then be transported to the drain outlet 110 through the core support structure 2.

[0048] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
