PROBLEM TO BE SOLVED: To provide a technique that can switch between a vacuum function and a blower function of an electric vacuum cleaner easily with a simple configuration, and can effectively use the blower function in a variety of situations.SOLUTION: In a suction/blowing device, the inside of a body part 111 is served as a main channel 101 for air, and the inside of an injection channel part 112 provided in the body part 111 is served as a subchannel 102 for air. When a suction airflow is formed in the main channel 101, a power fan 114b in a suction chamber 115 rotates and an injection fan 114a rotates in conjunction therewith so that the blowing airflow is formed in the subchannel 102. By switching a channel switching part 116 of a valve member provided in the joining position between the main channel 101 and the subchannel 102, the formation of the blowing airflow or a suction airflow can be easily switched. |
