Conventionally, vacuum cleaners have been configured to convert changes in air volume in the vacuum cleaner's air flow path into movement of the wind catcher plate, and to electrically detect and control this movement to change the input power of the electric blower.

To describe the operation of the embodiment configured as described above, air and dust are sucked into the dust box 2 from the air intake hole 3 through the floor nozzle, connecting pipe, hose, etc. by driving the electric blower 9. , dust is separated by a filter device 5, and clean air passes through an electric blower 9 and is exhausted into the motor case 8.

The exhaust gas filling the motor case 8 is first discharged from the exhaust hole 8b which is not provided with the wind receiving plate 19, but it cannot be completely exhausted from this exhaust hole 8b alone, and is exhausted from the exhaust hole 8a which is provided with the wind receiving plate 19. The wind pressure acts on the wind receiving plate 19, and the tension spring 2
3, the wind receiving plate 19 is pushed out in the direction of the arrow x shown in FIG. 3, centering on the shaft cylinder portion 19a.

In such a state, when the object to be cleaned is a floor or tatami mat, the ventilation resistance of the surface to be cleaned is small, so the amount of air sucked into the vacuum cleaner main body 1 increases, and the amount of air drawn into the vacuum cleaner main body 1 increases, and the motor case 8 The amount of air discharged also increases proportionally. Therefore, the opening degree of the wind receiving plate 19, that is, the rotation angle of the rotation shaft 15a of the variable resistor 15 changes greatly in the arrow X direction.

この時、風受板19が一定の回動角度以上にな

At this time, if the wind receiving plate 19 reaches a certain rotation angle or more, it is detected by the variable resistor 15, and the electronic control unit 30 controls the output to a low level based on the detection signal, and the electric blower 9 is operated at low rotation speed based on the output. The amount of air sucked into the vacuum cleaner main body 1 is reduced to a suction air amount suitable for cleaning floors and tatami surfaces.

In addition, when the surface to be cleaned is a carpet, there is more contact between the surface to be cleaned and the vacuum cleaner's suction tool (not shown), which increases ventilation resistance and causes suction into the vacuum cleaner body 1. The amount of air discharged from the motor case 8 decreases.

Therefore, the opening degree of the wind receiving plate 19, that is, the rotation angle of the rotating shaft 15a of the variable resistor 15 changes slightly in the direction opposite to the direction of the arrow X. Therefore, when the rotation angle becomes less than a certain rotation angle, it is detected by the variable resistor 15, and based on the detection signal, the electronic control unit 30 controls the output to high, and the output causes the electric blower 9 to rotate at high speed. Therefore, the amount of air sucked into the vacuum cleaner main body 1 increases, and a strong suction force is obtained on the carpet surface.

以上のように、被掃除面により吸引される風量

As described above, when the amount of air suctioned by the surface to be cleaned changes, the electric blower 9 is controlled and operated so that a constant amount of air within a certain range is constantly suctioned.

The air thus discharged from the exhaust holes 8a and 8b is discharged to the outside of the vacuum cleaner main body 1 through the outlet hole 40.
