Problems solved by technology

[0004] However, in the above-mentioned existing electric vacuum cleaners, the research on the conditions for releasing the forced stop after the electric fan is temporarily stopped (forced stop) for power saving and quietness is not enough.
For example, after a period of time has elapsed after the control device detects that the suction head has not touched the surface to be vacuumed (detected to be off the ground) according to the output information of the grounding detection device of the suction head, and forcibly stops the motor or the electric blower, the user only If the electric vacuum cleaner moves and touches the suction head of the electric vacuum cleaner and the switch is closed, the operation will start unintentionally (forced stop release)

Abstract

The present invention provides an electric vacuum cleaner which can compulsorily stops a motor when cleaning is not performed and can eliminate the incoordination feeling when the compulsory stopping is released. The electric vacuum cleaner comprises the following components: a flexible pipe (3) which is provided with an operation part (4) and can be freely detached and installed on a body (1); alengthened pipe (5) which can be installed and detached on the flexible pipe; a suction head (6) which can be freely installed and detached on the lengthened pipe and the flexible pipe and is provided with a grounding detector that detects whether contacts with a dust suction surface; and a control device (16) which drives and controls an electric motor according to a driving mode set by the operation part. Once the control device detects that the suction head does not contact with the surface which is to be executed with vacuum cleaning from the output information in the grounding detector, the control device controls for compulsively stopping the electric fan, and simultaneously, if a compulsory stopping releasing condition preset at the compulsory stopping state is satisfied, the control device controls the electric fan for operating for furthermore obtaining the suction force which is before the compulsory stopping or set beforehand.

Description

technical field [0001] The invention relates to an electric vacuum cleaner capable of reducing electric energy consumption. Background technique [0002] A typical structure of an existing electric vacuum cleaner is as follows. The body of the electric vacuum cleaner is provided with an electric fan, and the suction head uses the suction airflow generated by the electric fan to inhale dust, and is connected to the body of the electric vacuum cleaner through a hose or the like. The above-mentioned suction head is provided with a rotating brush and a motor that drives the rotating brush to rotate, and at the same time, a wire that supplies power to the motor of the suction head from the body of the electric vacuum cleaner is also provided. This power supply wire is provided with a switch, and is equipped with a ground detection device for detecting whether the suction head is in contact with the vacuumed surface. Therefore, when the switch is closed and the ground detection ...
