Description

Air leakage prevention structure of automobile air conditioner

Technical Field

The utility model relates to an automobile air conditioner, concretely relates to automobile air conditioner leak protection wind structure.

Background

After the automobile air conditioner operates in a refrigeration mode, condensate water can appear on the evaporator, and in order to smoothly discharge the condensate water, a water drainage port is formed in a sealing rib, which is in contact with the evaporator, of the lower shell. However, air is discharged from the drain port through the drain pipe while being discharged, which causes a loss of air volume of the air conditioning box and affects air conditioning performance.

Although the document CN209445570U discloses a condensed water drainage structure of an evaporator of an automobile air conditioner, which is an S-shaped drainage elbow made of plastic, the upper end of the S-shaped drainage elbow is hermetically connected with a drainage port of an HVAC base of the automobile air conditioning system, and a drainage nozzle with a necking structure is arranged at the lower end of the S-shaped drainage elbow, the wall thickness B of the S-shaped drainage elbow is five times that of the drainage nozzle, namely B is 5B; the bottom surface of the drainage nozzle is provided with an open slot, and the side wall of the drainage nozzle is provided with a drainage seam which runs through the open slot on the bottom surface. However, the structure solves the drainage problem of the condensed water of the automobile air conditioner evaporator under the condition of large air volume of the blower from the outside of the lower shell.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a vehicle air conditioner leak protection wind structure to reduce the amount of wind loss, optimize refrigeration performance.

In order to achieve the above purpose, the present invention adopts the following technical solution.

An air leakage preventing structure of an automobile air conditioner comprises an air conditioner lower shell, wherein a drain pipe is arranged on the air conditioner lower shell, a water outlet is formed in a sealing rib in contact with an evaporator, a blocking part is arranged on the right opposite side of the water outlet, and the distance between the blocking part and the water outlet is controlled to be 7-12 mm.

Preferably, the baffle part is a U-shaped baffle, a V-shaped baffle or an arc baffle.

Preferably, the sealing ribs are of a multi-section structure, and the space between adjacent sections of sealing ribs is 7-12 mm.

Preferably, the sealing ribs comprise a first sealing rib, a second sealing rib and a third sealing rib which are arranged at intervals, the blocking part comprises a first arc-shaped baffle plate, a second arc-shaped baffle plate and a third arc-shaped baffle plate, the first arc-shaped baffle plate and the second arc-shaped baffle plate are respectively positioned on two sides of a water outlet between the first sealing rib and the second sealing rib, and the third arc-shaped baffle plate is positioned on one side of the water outlet between the second sealing rib and the third sealing rib.

Since the technical scheme is used, the utility model discloses the structure can change the flow direction of wind through fender portion, and guide wind side flow reduces wind and directly blows off from outlet and drain pipe to reduce the amount of wind and scatter and disappear, optimize refrigeration performance.
