TECHNICAL FIELD

[0001] The utility model relates to vehicle air conditioner technical field especially, relates to a vehicle air conditioner convenient for condensate water discharge and vehicle. BACKGROUND

[0002] The vehicle air conditioner is used for adjusting and controlling the temperature, humidity, flow rate and other parameters of the air in the vehicle environment, so as to meet the user's demand for the temperature in the vehicle. However, in the design and use of the vehicle air conditioner, a problem often neglected is the effective discharge of condensate water.

[0003] In the design of traditional vehicle air conditioners, the drainage structure of condensate water is often not fully considered, resulting in the problem of condensate water backflow during use, especially when the air passes through. Condensate water backflow not only affects the normal operation of the vehicle air conditioner and reduces its refrigeration or heating efficiency, but also may cause damage to the vehicle interior, such as corrosion of electrical components and breeding of bacteria.

[0004] Specifically, when the vehicle air conditioner is running, condensate water is produced on the surface of the evaporator. If the drainage structure is not reasonably designed, the condensate water may not be discharged in time, but accumulated in the air duct. When the fan is working, the airflow generated may blow the accumulated condensate water to the wrong direction, causing condensate water to backflow to the evaporator or other components, thereby causing a series of problems.

[0005] Therefore, it is necessary to optimize the drainage structure of condensate water in the vehicle air conditioner to solve the problems existing in the prior art. SUMMARY

[0006] In order to solve the problems existing in the prior art, the utility model provides a vehicle air conditioner convenient for condensate water discharge and a vehicle, which is used for guiding the discharge of condensate water, optimizing the drainage efficiency and preventing the accumulation of condensate water.

[0013] Further, the bottom wall portion of the mounting groove is provided with a water guide slope and a plurality of spaced support steps, the upper surfaces of the plurality of support steps are at the same horizontal plane to support the evaporator.

[0014] Further, the other two sides of the mounting groove have upwardly extending wall portions, and the water receiving cavities suitable for receiving condensed water are defined between the two wall portions and the bottom wall.

[0015] Further, the side of the mounting groove away from the arc-shaped wall portion is provided with a baffle to prevent water vapor from flowing back to the evaporator.

[0016] Further, the vehicle-mounted air conditioner further comprises a compressor, a condenser, an outer fan, and an inner fan, the outer fan, the condenser, the compressor, the evaporator, and the inner fan are arranged in sequence on the casing.

[0021] The drainage channel is defined between the side wall of the casing and the hollow arc-shaped wall portion arranged thereon and communicates with the drainage port, for guiding the condensed water to drain out, achieving efficient and smooth drainage of the condensed water. The arrangement of the drainage channel not only considers the natural flow path of the condensed water, but also effectively avoids the problem of backflow of the condensed water caused by air flow through the guidance of the arc-shaped wall portion. This design ensures that the condensed water can be quickly and accurately drained out, thereby maintaining the dryness and cleanliness of the internal environment of the vehicle-mounted air conditioner.
