An air injection type vessel washer is provided to improve washing efficiency by forming injection holes at an air injection nozzle so that injection holes have tilt angles and air is injected all over the inner wall of a vessel. An air injection type vessel washer comprises a housing(2) and an air injector(10). The air injector includes a support unit(20), an inner housing(30), an elevating cylinder(45), an elevating block(50), a cover plate(80), an air supply fan(60), and an air injection nozzle(90). The support unit is fixed in the housing of the vessel washer. The inner housing is arranged on the support unit, and equipped with a mounting portion(31) where an inlet port(1a) of a vessel(1) is mounted, and an air outlet port(32) connected to an air outlet unit(3e) through an open/shut valve(v). The elevating cylinder is fixed beneath the support unit so that the elevating cylinder operates by air or hydraulic pressure. The elevating block is supported by the support unit, and has an air injection port(51), an air injection channel(52) communicated to the air injection port. The elevating block has an installation space(53) for installation of the air supply fan. The cover plate seals the installation space of the elevating block, and elevates together with the elevating block. The air supply fan is mounted on the cover plate, and has a rotation shaft with a hollow portion communicated to the air injection channel. The air injection nozzle is fitted to the rotation shaft, and has an air injection channel(91) communicated to the hollow portion. The air injection nozzle has an outer surface where a plurality of air injection holes(92) are formed so that the air injection holes are communicated to the air injection channel. The air injection nozzle elevates together with the elevating block.
