RECREATIONAL VEHICLE AIR CONDITIONER, AND DRAINAGE EARLY-WARNING METHOD AND DEVICE FOR RECREATIONAL VEHICLE AIR CONDITIONER

The present application relates to the technical field of air conditioners, and provides a recreational vehicle air conditioner, and a drainage early-warning method and device for a recreational vehicle air conditioner. The recreational vehicle air conditioner comprises an air conditioner body, multiple dual-level liquid level sensors, and multiple flow velocity sensors; the multiple dual-level liquid level sensors are arranged in the air conditioner body at the same height, and each dual-level liquid level sensor comprises a low-level detection end and a high-level detection end, wherein the elevations of the low-level detection end, the high-level detection end and an air outlet increase sequentially; and the multiple flow velocity sensors are arranged between the low-level detection ends and the high-level detection ends of the multiple dual-level liquid level sensors in a one-to-one correspondence manner. Water level information and flow velocity information in the air conditioner body are acquired by mea
