PURPOSE:To easily remove contaminants such as oil and the like adhering to an air filter part by providing the air filter provided with closely arranged heating elements on the side of a suction port. CONSTITUTION:An air discharging device 3 is provided with an air filter 11 between a main body 4 and a main body cover 10. The air filter 11 is formed into a mesh shape by closely intertwining fine linear heating elements 11' in a vertical direction A and a horizontal direction B. By supplying power to a switch 13, heat is generated. Contaminants such as dust and oil adhere to the air filter 11 which has been used for a long period of time. However, these contaminants are removed by turning on the switch 13 to generate heat in the air filter 11 itself whereby contaminants are thermally decomposed and removed. |
