Embodiment 1

[0028] figure 1 It is a side view of the electric vacuum cleaner in the first embodiment of the present invention, figure 2 It is the circuit block diagram of the electric vacuum cleaner.

[0029] exist figure 1 and figure 2 Among them, 1 is the motor for driving the rotating brush 2 to sweep up the dust on the surface to be cleaned, 3 is the electric fan for attracting dust, 4 is the dust collecting chamber for collecting the dust, and 5 is for controlling the A motor control device for the rotational speed of the motor 1 , 6 is an input control device for controlling the electric fan 3 , and 7 is a current detection device for detecting the current flowing in the motor control device 5 .

[0030] 8 is a temperature detection device for detecting the temperature of the motor 1 . In this embodiment, the temperature detecting means 8 is constituted by a low-cost (self-recovery type) thermostat 9 and is connected in series with the motor 1 . When the temperature of the ...

Embodiment 2

[0038] image 3 It is a cross-sectional view of some important structures of the electric vacuum cleaner in the second embodiment of the present invention, Figure 4 It is the circuit block diagram of the electric vacuum cleaner. In addition, for the same parts as those in the previous embodiment, only the same symbols are assigned here, and repeated explanations thereof are omitted here.

[0039] exist image 3 and Figure 4 Among them, 11 is a motor drive availability detection device for judging whether the motor 1 can be driven. In this embodiment, a micro switch 12 is used to detect the state of the electric vacuum cleaner, specifically to detect that the electric vacuum cleaner is in a state that does not need to drive the rotating brush 2, that is, the main body 15 is in an upright shelving state ( image 3 a), still in the state that the main body 1 that should drive the rotating brush 2 is pulled down, that is, the dust suction state ( image 3 b). 12a is the op...

Abstract

A vacuum cleaner includes an electric motor for driving a rotational brush for brushing dust particles from a surface to be cleaned, an electric blower for generating a suction air stream for sucking in the dust particles, a dust chamber for collecting the dust particles therein, a motor controller for controlling the electric motor, an input controller for controlling the electric blower, a current detector for detecting a current flowing through the motor controller, and a temperature detector for detecting a temperature of the electric motor. If the temperature of the electric motor increases over a predetermined temperature value, the electric motor is stopped and the stoppage of the electric motor is detected by the current detector.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, and more particularly, to a control method of a motor for driving a rotating brush that sweeps up dust. Background technique [0002] The structure of the existing electric vacuum cleaner is generally as Figure 5 and Image 6 shown in . The composition thereof will be described in detail below. [0003] like Figure 5 As shown in , the body 50 of the vacuum cleaner is provided with an electric blower 51 for attracting dust, and the suction side of the electric blower 51, that is, the upper side, is provided with a dust collection chamber 52 for collecting dust. The front part of the vacuum cleaner body 50 is provided with a hose 60 communicating with the dust collection chamber 52, and the other end of the hose 60 is connected with the suction head 80, and the suction head 80 is provided with a rotating brush 53 and a motor 81 for driving it. and other parts. Additionally, if Image 6 A...
