Problems solved by technology

[0009] Therefore, if it is desired to use an isolation transformer to detect (or correct) fluctuations in the power supply voltage, an adjustment circuit and a feedback circuit for reducing deviations or fluctuations in the output voltage are required, resulting in high cost.

Abstract

The invention provides an electric dust collector and electric device. The electric dust collector comprises an electric pressure fan (1) for absorbing the dust, an electric pressure fan control part (2) for controlling the electric pressure fan (1), a control part (3) for outputting the power signal of the electric pressure fan (1), a signal transmitting part (4) for transmitting the power signal from the control part (3) to the electric pressure fan control part (2), and a voltage generating part (5) of an insulated transformer (6) for insulating the control part (3) from a primary side power supply (13) and applying the motion voltage, wherein, the phase difference of a secondary side voltage phase and the primary side voltage phase of the insulated transformer (6) varies according to the primary side supply power voltage. In this way, the variation of the power supply voltage can be detected with a reduced and cheap structure.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner and electric equipment for collecting dust by utilizing the suction force of a built-in electric blower. Background technique [0002] As far as electric vacuum cleaners are concerned, floor-moving (canister) type vacuum cleaners are generally popular. In such a vacuum cleaner, an input of an electric blower disposed in the vacuum cleaner main body is operated by an operation unit provided on a handle portion of a hose detachably connected to a connection portion of the vacuum cleaner main body. The control unit in the main body of the vacuum cleaner detects the input information of the operation unit, and drives the electric blower according to the input information. That is, the input of the electric blower can be arbitrarily set through the control unit by the operation of the operation unit. The operation part and the cleaner main body are electrically connected through the connection te...
