However, since the doors and windows of the air conditioner are usually closed during operation, the oxygen content in the air in the indoor space is low. For this reason, the outdoor unit of the air conditioner of the present invention is equipped with an oxygen generator 2 through which the oxygen generator 2 can remove the air in the air. The oxygen is separated, and this part of oxygen is sent into the indoor space through the oxygen delivery pipe, which can significantly increase the oxygen content in the air in the indoor space, thereby improving the user experience. Since the oxygen generator 2 can deliver pure oxygen to the room, the delivery flow is greatly reduced compared to the fresh air blower, so the oxygen delivery pipeline can enter the room from the through-wall hole of the in-line pipe between the indoor unit of the air conditioner and the outdoor unit of the air conditioner. Space, no need to punch separately. 2, usually the outdoor unit of the air conditioner includes a cabinet 1, and the oxygen generator 2 includes a housing 26. The four corners of the housing 26 respectively have mounting plates extending downwards and upwards. Screw holes are formed on the mounting plates.
