The invention discloses a wall-mounted hair drier capable of slidably blowing a towel rack and hair. The wall-mounted hair drier comprises a motor, an electric wire, a pulley rail, pulleys, an air outlet, a shell, a switch, fan blades, a control circuit board, a thermostat electric heating net, a plug, the metal towel rack, nail holes and an ozone generator. At present, hair driers on the market are mostly handheld hair driers and need a user to hold with one hand all the time when used in a bathroom, thereby being quite inconvenient; further, towels on the towel racks are always wet and result in generation of a great quantity of bacteria, thereby being very unsanitary; solutions to the two conditions above require two different electric appliances, which cause wastes. The wall-mounted hair drier capable of slidably blowing the towel rack and the hair is provided for overcoming the defects. When needing to drying hair, a user can move the hair drier with hands to a vacancy avoiding the towel rack prior to using the hair drier normally; when hair drying is not required, the hair drier can be moved above the towel rack, and then wet towels can be blown dry by hot air with ozone generated by the ozone generator, so that bacterium reduction is realized.
