Abstract

1505632 Vacuum cleaners ELECTROLUX Ltd 13 Dec 1976 51929/76 Heading A4F [Also in Division H1] A vacuum cleaner comprising a motor/fan unit (not shown) having an on/off switch 25 actuable by a member 27, is provided with a servomotor 10 which is effective to position a rocker arm 21 to maintain the switch 25 closed only if a dust bag is in position in the cleaner. As shown depression of member 27 causes a finger 29 to bear on a portion 21a of the arm and pivot the arm anticlockwise so that the portion 21a closes the switch so starting the fan. The resulting negative pressure caused by the dust bag (for example arranged as disclosed in Specification 1494310) is applied to chamber 15 and causes the diaphragm 14 to move to the left and so move the rocker arm 21, whose pivot 22 is mounted in grooves 23, to the left so that even when the member 27 is released the portion 21a holds the switch closed. Subsequent depression of member 27 causes the finger 29 to bear on the portion 21 b and so pivot the arm 21 clockwise to open the switch, the arm returning to its original position under the action of a spring 30. If there is no dust bag in the cleaner, the diaphragm 14 and hence the arm 21 do not move to the left so that on release of the member 27 the switch is opened.
