Air outlet and return air system of air conditioner for four-wheel vehicle

Abstract

The invention belongs to the technical field of four-wheeled relaxation scooters, and provides an air outlet and return system of a vehicle-mounted air conditioner of a four-wheeled vehicle. The air outlet and return system of the vehicle-mounted air conditioner of the four-wheeled relaxation scooter comprises a left air outlet I (16), a left air outlet II (17), a right air outlet I (18), a right air outlet II (19) and a defrosting and demisting opening (20), wherein the left air outlet I (16), the left air outlet II (17), the right air outlet I (18), the right air outlet II (19) and the defrosting and demisting opening (20) are all formed in an instrument desk; a left air outlet pipe II (7) of a three-way structure is arranged corresponding to the left air outlet I (16) and the left air outlet II (17); the left air outlet pipe II (7) communicates with a left air outlet (14) in an evaporation box; a right air outlet pipe II (5) of a three-way structure is arranged corresponding to the right air outlet I and the right air outlet II and communicates with a right air outlet (12) in the evaporation box; and the evaporation box is further provided with an air return opening (11). By means of the air outlet and return system, it is guaranteed that the ventilation quantity of an air outlet pipeline system is increased to the maximum extent in a limited space.

Description

technical field [0001] The invention belongs to the technical field of four-wheel leisure scooter, and mainly proposes an air outlet and return air system of a vehicle-mounted air conditioner for a four-wheel vehicle. Background technique [0002] So far, the known vehicle-mounted air conditioners include a condenser assembly, an evaporator box assembly, a compressor assembly, an intake and exhaust pipe assembly, an air outlet pipe assembly, and a return air pipe assembly. The size of the car is small, and the installation space is small. The air conditioner installed on the four-wheel leisure scooter takes up a lot of space for the air outlet and return air piping system. The design is not smooth and does not conform to aerodynamics. This kind of air outlet and return air pipeline system layout designed for avoidance will affect the effect of the vehicle's air outlet and return air system. The existing structure of the air return system cannot meet the needs of the air out...
