在到达第一预设位置后，曲柄元件1的第二传动轴12进入第一分支滑道202，第二传动轴12与第一分支滑道202产生抵接力，进而控制第一连杆2的第一端部滑块211向第一分支轨道42内运动，且，此时第一连杆2的第一协作滑块212继续作直线运动， 第一连杆2在第一端部滑块211和第一协作滑块212的限定下运动改向，且，第二连杆3继续作直线运动，因此，导风板6在第一连杆2和第二连杆3的共同带动下向上开启，如图12-14所示。
在到达第一预设位置后，曲柄元件1的第二传动轴12进入第二分支滑道203，第二传动轴12与第二分支滑道203产生抵接力，进而控制第一连杆2的第一端部滑块211向第二分支轨道43内运动，且，此时第一连杆2的第一协作滑块212继续作直线运动，第一连杆2在第一端部滑块211和第一协作滑块212的限定下运动改向，且，第二连杆3继续作直线运动，因此，导风板6在第一连杆2和第二连杆3的共同带动下向下开启，如图15和16所示。
可选地，本公开实施例提供的空调室内机为大导板式空调室内机，本公开实施例提供的空调室内机的导风板6可以在导风板6处于关闭状态时，导风板6完全封闭出风口。可选地，本公开实施例提供的空调室内机还可以为柜机或风管机等。
