Abstract
PURPOSE: To ensure that the outside air is sucked in when the negative pressure in a dust collecting box has increased and that a pointer returns instantaneously by providing a connection pipe which bypasses the outside air on the movement of the pointer.
CONSTITUTION: A thin connection pipe 28 is so arranged to connect an elbow 19 with the gap 27 formed between a pipe 20 and a pointer 21 and a cover 24. During cleaning, with a filter clogged or with suction means stopped up, the negative pressure in the elbow 19 increases and a pointer 21 moves. From this time on, the outsie air flows into the elbow 19 through the pipe 28. With the suction means released from stop-up, the negative pressure in the elbow 19 decreases and the pointer 21 returns instantaneously. As a result, the airflow for preventing heating can be increased and safety is enhanced.
