The invention provides a bottom shell component and an air conditioner with the bottom shell component. The bottom shell component comprises a bottom shell, an anti-water-leakage device and a water discharge pipe, wherein the bottom shell is provided with a water discharge mouth; the anti-water-leakage device is installed at the water discharge mouth and is provided with a seal position for closing the water discharge mouth and a water discharge position for opening the water discharge mouth; and the water discharge pipe is arranged in the water discharge mouth in an inserted manner to make the anti-water-leakage device be switched from the seal position to the water discharge position and is separated from the water discharge mouth to make the anti-water-leakage device be switched from the water discharge position to the seal position. According to the bottom shell component and the air conditioner with the bottom shell component, by means of the manner that the anti-water-leakage device is added at the water discharge mouth in the bottom shell, when the water discharge pipe is pulled out, the anti-water-leakage device can seal the water discharge mouth, and liquid inside the bottom shell is prevented from flowing out; and after the water discharge pipe is installed, the anti-water-leakage device is opened, the bottom shell discharges water normally, the problem that air passage residual liquid flows out after the water discharge pipe is disassembled from an after-sale wall hanging machine is solved, and after-sale operations are facilitated.
