Embodiment

[0014] A kind of anti-leakage structure of automobile air conditioner, such as figure 1 As shown, the air conditioner lower casing 7 is included, and the air conditioner lower casing 7 is provided with a drain pipe 9, figure 1 The middle drain pipe 9 refers to the port of the drain pipe, and the rest of the drain pipe is blocked. The drain port 8 provided on the sealing rib in contact with the evaporator is provided with a retaining portion on the opposite side of the drain port 8, and the retaining portion is connected to the drain port. The spacing of 8 is controlled to be 7-12mm.

[0015] Optionally, the baffle is a U-shaped baffle, a V-shaped baffle and an arc-shaped baffle.

[0016] In this embodiment, the sealing rib has a multi-segment structure, and the distance between adjacent sealing ribs is 7-12 mm.

[0017] In this embodiment, the sealing ribs include sealing ribs one 1, sealing ribs two 4 and sealing ribs three 6 arranged at intervals, and the retaining portion...

Abstract

The invention provides an automobile air conditioner air leakage prevention structure. The structure comprises an air conditioner lower shell, wherein a drainage pipe is arranged on the air conditioner lower shell, a drainage port is formed in a sealing rib making contact with an evaporator, a blocking part is arranged on the side right opposite to the drainage port, and a distance between the blocking part and the drainage port is controlled to be 7-12 mm. The structure is advantaged in that the flow direction of air can be changed through the blocking part, the air side flow is guided, the air is prevented from being directly blown out of the drainage port and the drainage pipe, air loss is reduced, and refrigeration performance is optimized.

Description

technical field [0001] The invention relates to an automobile air conditioner, in particular to an air leakage prevention structure of the automobile air conditioner. Background technique [0002] When the car air conditioner is in the cooling mode, condensed water will appear on the evaporator. In order to discharge the condensed water smoothly, a drain port will be opened on the sealing rib where the lower case is in contact with the evaporator. However, while the water is being drained, the wind also flows out from the drain outlet through the drain pipe, which causes the air volume loss of the air conditioning box and affects the performance of the air conditioning. [0003] Although document CN209445570U discloses a condensed water drainage structure of an automobile air-conditioning evaporator, which is an S-shaped drainage elbow made of plastic, the upper end of the S-shaped drainage elbow is sealed and connected with the drain outlet of the HVAC base of the automobil...
