Claims

[Scope of Claim for Utility Model Registration] A vacuum cleaner body that forms a dust collection chamber communicated with a suction port, has a built-in electric blower, and is equipped with a control means for controlling input to the electric blower, and this vacuum cleaner. a suction hose provided with a manual operation part that is detachably connected to the main body of the vacuum cleaner and has operating means consisting of a plurality of switches for operating the control means; A detection switch for detecting the presence or absence of the attached dust collection bag, and a notification means operated based on the operation of the detection switch to detect that the dust collection bag is not attached, are provided in the hand operation section of the suction hose. A current control resistor is provided corresponding to each switch of the operating means, and the vacuum cleaner body includes a constant voltage power supply device, a voltage detection resistor connected in series with the current control resistor to the constant voltage power supply device, and a voltage detection resistor connected in series with the current control resistor, and the detection switch. and a shunt resistor connected in series with the detection switch and in parallel with the voltage detection resistor, and the control means controls the load flowing through the voltage detection resistor by the operation of the detection switch to detect that the dust collection bag is not attached. A vacuum cleaner characterized in that input is controlled so that the electric blower is not driven in response to changes in current, and the notification means is operated.
