Embodiment Construction

[0031] Examples such as Figures 1 to 4 As shown, a first circulating damper mechanism in an automobile air conditioner includes a blower box 1, a first circulating damper 2, a second circulating damper 3 and a linkage mechanism.

[0032] Wherein the first circulation damper 2 is located at the first circulation air inlet of the blower box 1, the second circulation damper 3 is located at the second circulation air inlet of the blower box 1, and the two ends of the linkage mechanism are respectively connected with the first circulation damper 2 and the second circulation air inlet. Throttle 3 is movably connected.

[0033] The connecting rod mechanism can be located in the casing of the blower case 1 or outside the casing of the blower case 1. In order to save the assembly space of the air conditioner on the automobile, the connecting rod mechanism is placed in the casing of the blower case 1.

[0034] like Figure 5 As shown, in this embodiment, the connecting rod mechanism ...

Abstract

This invention discloses a first circulation air door unit in car air-conditioning including a fan box with a first circulation air intake, a first circulation air door, a second circulation door and a connecting rod unit, in which, said first circulation air door is installed on the first air intake rotationally, the second door is mounted at the second air intake rotationally, both ends of the connecting rod are connected with the two doors movably and the first door, the rod are linkage with the second door. This invention sets a circulation air door at the first and the second air intakes of the fan box separately and is connected by the connecting rod, when a door rotates, it drives the other to rotate to realize switch of inside and outside circulation by closing one door and opening the other.

Description

technical field [0001] The invention relates to an internal and external circulation damper mechanism of an automobile air conditioner. Background technique [0002] At present, there are two main air intake methods for automobile air conditioners, one is external circulation air intake, and the other is internal circulation air intake. When fresh air is needed, the damper is turned to the inner circulation air inlet, the outer circulation air inlet is fully opened, the inner circulation air inlet is completely closed, and the air enters the fan inlet of the air conditioner from the outside of the car. The air intake mode at this time is the inner circulation mode; When the air quality inside the car is good, or the air outside the car is turbid, the damper is turned to the air inlet of the outer circulation, the air inlet of the inner circulation is fully opened, the air inlet of the outer circulation is completely closed, and the air directly enters the fan inlet of the ai...
