AI Technical Summary

Technical Problem

Condensate from the evaporator splashing into the rear cooling aisle can cause water to blow onto passengers, affecting the user experience and potentially corroding or burning out electrical components.

Method used

Design a drainage component including a water collection tank and a connecting pipe. The connecting pipe connects the rear exhaust cooling channel to the water collection tank to collect and drain splashed water. The water inlet of the water collection tank is higher than the bottom wall, and the drain outlet is higher than the water inlet. The connecting pipe is set at an angle to prevent backflow.

Benefits of technology

It effectively prevents condensation from blowing onto passengers, avoids corrosion or burnout of electrical components, simplifies the drainage structure, adapts to condensation backflow under special road conditions, and improves user experience.

Abstract

The application discloses a drainage assembly and a vehicle. The drainage assembly is used for an air conditioning system with an evaporator, and comprises a water collecting tank for receiving condensed water of the evaporator, an air exhaust component, and a connecting pipe. The air exhaust component comprises a rear cold air passage for allowing cold air exchanged with the evaporator to flow through, and the rear cold air passage receives water splashed from the evaporator. The connecting pipe connects the rear cold air passage and the water collecting tank. In this way, the water splashed from the evaporator into the rear cold air passage can flow into the water collecting tank through the connecting pipe, and then be discharged to outside of the vehicle through the water collecting tank. The water splashed from the evaporator is not easy to gather in the rear cold air passage, so that the situation that the water splashed from the evaporator blows to passengers is improved, and user experience is improved. In addition, the rear cold air passage is connected with the water collecting tank through the connecting pipe, and the splashed water is discharged through the water collecting tank, so that an additional drainage structure is not needed to be arranged, the structure for discharging the splashed water is simple, and electrical devices around the rear cold air passage can be prevented from being burnt or corroded.
