Description

Technical Field

[0001] This utility model relates to the technical field of automotive air conditioning unit equipment, specifically to a structure for draining condensate inside an air conditioning unit. Background Technology

[0002] When the air conditioner is turned on in cooling mode, the evaporator starts working. The surface temperature of the evaporator is lower than the temperature of the intake airflow, so water vapor condenses on the evaporator surface. Due to gravity, water droplets gather at the bottom of the evaporator. Under the action of the blower, the water droplets gathered at the bottom are blown out in a parabolic shape. The current air conditioning unit uses a drip tray structure to help the internal condensate drain out of the vehicle through a designated path. However, the existing drip tray structure cannot guarantee that all the condensate will drain out from here without passing through the rear air vent. While draining the water, it cannot prevent the air from blowing directly out of the drain outlet, which can easily cause backflow and affect the normal operation of the air conditioning system. Utility Model Content

[0003] Technical objective: To address the shortcomings of existing condensate tray structures in air conditioning units, this utility model discloses a structure for draining condensate inside an air conditioning unit, which reduces return air while achieving smooth collection and discharge of condensate.

[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution: A structure for draining condensate inside an air conditioning unit includes a water collection tray located below the evaporator of the air conditioning unit and a drain outlet located at the lowest point of the water collection tray surface. The surface of the water collection tray extends vertically from the air outlet side of the evaporator along the air outlet surface of the evaporator; the entire surface of the water collection tray is inclined towards the side where the drain outlet is located.

[0005] Preferably, the water receiving tray of this utility model is provided with several baffles along the air flow direction of the evaporator outlet. The baffles are perpendicular to the surface of the water receiving tray, and the surfaces of adjacent baffles are parallel to each other, dividing the surface of the water receiving tray into several mutually separated tray areas. A water passage hole for the collection of condensate is opened between the contact surfaces of the baffles and the water receiving tray. The water passage hole is located at the lowest point of the corresponding tray area, and the adjacent tray areas are connected through the water passage hole for the collection of condensate.

[0006] Preferably, the length of the water receiving tray of this utility model is set according to the maximum wind speed passing through the evaporator when the air conditioning unit is running, so that the condensate blown out by the air conditioning unit at the maximum wind speed falls within the area of ​​the water receiving tray.

[0007] Preferably, the drain outlet of this invention is located on the side of the water receiving tray near the bottom of the evaporator.

[0008] This utility model also discloses an air conditioning unit, which has the above-mentioned structure for draining condensate inside the air conditioning unit, for discharging condensate from the evaporator.

[0009] Beneficial effects: The structure for draining condensate inside an air conditioning unit disclosed in this utility model, as well as the air conditioning unit itself, can achieve efficient collection and discharge of condensate through the inclined water receiving tray. The length of the water receiving tray is designed according to the maximum wind speed through the evaporator during the operation of the air conditioning unit, reducing the risk of condensate falling into the air duct inside the air conditioning unit and ensuring the collection effect of condensate. At the same time, the wind baffle is set on the surface of the water receiving tray to separate the airflow, which can reduce the airflow flowing out through the drain outlet and reduce the impact of return air phenomenon. Attached Figure Description

[0010] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below.

[0011] Figure 1 This is a schematic diagram of the structure of the air conditioning unit of this utility model; Among them, 1-evaporator, 2-water receiving tray, 3-drain outlet, 4-wind baffle, 5-water passage hole, 6-blower, 7-air inlet casing. Detailed Implementation

[0012] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0013] like Figure 1 As shown, this utility model discloses a structure for draining condensate inside an air conditioning unit and an air conditioning unit. The air conditioning unit includes a blower 6, an air inlet housing 7, and an evaporator 1. The air from the blower 6 enters the vehicle through the air inlet housing 7. In cooling mode, the air is cooled by the evaporator 1 upon entry. At this time, the surface temperature of the evaporator 1 is lower than the air temperature blown by the blower 6, and water vapor condenses on the surface of the evaporator 1, which is the condensate that this utility model aims to collect.

[0014] The structure of the condensate drain of this utility model includes a water collection tray 2 located below the evaporator 1 of the air conditioning unit and a drain outlet 3 located at the lowest point of the surface of the water collection tray 2. The drain outlet 3 is located on the side of the water collection tray 2 near the bottom of the evaporator 1. The surface of the water collection tray 2 extends vertically from the air outlet side of the evaporator 1 along the air outlet surface of the evaporator 1. The entire surface of the water collection tray 2 is inclined towards the side where the drain outlet 3 is located. The inclined design of the water collection tray 2 allows condensate to be smoothly collected and discharged through the drain outlet 3. At the same time, this utility model places the water collection tray 2 at the bottom of the evaporator and towards the drain outlet 3. The vertical extension on the air outlet side is preferred. The length of the water collection tray 2 is set according to the maximum wind speed passing through the evaporator 1 when the air conditioning unit is running. When the air conditioning unit is running at the maximum wind speed, the condensate blown out falls within the area of ​​the water collection tray 2. The design size of the corresponding air conditioning unit water collection tray can be determined through simulation experiments. Compared with the method of collecting condensate directly by gravity, this utility model can block and recover the condensate droplets blown out by the air intake, enhance the condensate collection effect, and reduce the risk of condensate entering the car air conditioning duct.

[0015] To prevent a large amount of incoming air from flowing directly out through the drain outlet 3 and affecting the air conditioning efficiency, the water receiving tray 2 of this invention is provided with several baffles 4 along the airflow direction of the evaporator 1. The baffles 4 are perpendicular to the surface of the water receiving tray 2, and the surfaces of adjacent baffles 4 are parallel to each other, dividing the surface of the water receiving tray 2 into several separated tray areas. A water passage hole 5 is opened between the contact surface of the baffles 4 and the water receiving tray 2 for the collection of condensate. The water passage hole 5 is located at the lowest point of the corresponding tray area of ​​the water receiving tray 2, and the adjacent tray areas are connected through the water passage hole 5 for the collection of condensate. The baffles 4 can separate the drain outlet 3 from the air duct to a certain extent, thereby reducing the return air phenomenon and ensuring the air conditioning cooling effect under cooling conditions. At the same time, it can also reduce the impact of cold air entering from the drain outlet 3 on the operation of the air conditioner when heating.

[0016] This utility model also discloses an air conditioning unit with the above-mentioned structure for draining condensate inside the air conditioning unit. It drains condensate from the evaporator. In the cooling mode, the evaporator 1 starts to work. The surface temperature of the evaporator 1 is lower than the temperature of the intake airflow. Water vapor condenses on the surface of the evaporator. Due to gravity, it gathers into water droplets below the evaporator. Under the action of the blower, the water droplets gathered below are blown out in a parabolic shape. The water collection tray 2 can effectively intercept the blown-out condensate into the water collection tray 2. The condensate flows through the water passage 5, passes through each wind deflector 4, and reaches the drain outlet 3. The water is discharged outside the vehicle from the drain outlet 3, thereby achieving the drainage effect. The wind deflectors also reduce the impact of the return air on the operation of the air conditioning.

[0017] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
