The invention provides a vertical air-conditioner which can clean a blower configured on the vertical air-conditioner and assembly and disassembly of an air filter more easily, and also can improve the reasonability of maintenance. The vertical air-conditioner configures a blower and a heat exchanger in a longitudinal direction of lengthways main body, and leads the indoor air inhaled by the blower to be subjected to the heat exchanger so as to generate the adjusted air after heat exchanger and supply the adjusted air into the room; the vertical air-conditioner installs an upper part front plate provided with the discharging holes of the adjusted air on the upper half part in the front of the main body, meanwhile, one side end, which is formed with an inhalation hole with the air inhaled into the room and installed at the lower part front plate of the lower half part in front of the main body, is in rotatable shaft support on the main body, thereby the lower part front plate can be opened in single direction.
