Abstract

PURPOSE:To improve cleaning-efficiency, by a method wherein the title cleaner has both an automatic operation mode in which the power inputted to an electric fan is varied according to the amount of detected dust and a manual operation mode in which its power is preset at a specified value, and when an electric suction implement switch for a floor is pushed, the mode is not only shifted in the automatic operation, but a rotary brush is operated. CONSTITUTION:The title cleaner has both an automatic operation mode in which the power inputted to an electric fan 7 is automatically controlled according to the amount of the dust detected by a dust sensor 17 and a manual operation mode in which its power is manually selected. While the electric fan 7 is operated in the automatic operation mode or in the manual operation mode, a motor 13 is started or stopped by a rotary brush switch 8. While the electric fan is, however, stopped, the motor 13 is started when the rotary brush switch 8 is pushed, and the rotary brush is not only rotated but the mode is automatically shifted in the automatic operation. In the automatic operation mode, by only one push of the rotary brush switch 8, the operation of the cleaner with properly-inputted power level and the movement of the rotary brush for an electric suction implement are done at the same time. In this way, the switch operating times for the cleaner can be lessened and the properly-inputted power for cleaning is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum cleaner equipped with an electric floor suction device used in general households.

BACKGROUND OF THE INVENTION The internal structure of a conventional vacuum cleaner of this type will be described below with reference to the drawings.

6 and 7, a hose 33, an extension pipe 34, and an electric floor suction device 35 are connected to the suction port 32 of the main body 31. A hand switch 36 is provided at the tip of the hose 33 to control an electric blower 37 disposed inside the main body 31. An electric floor suction tool 35 is installed near the hand switch section 36.
A switch 38 for turning ON/OFF the rotating brush 39 of
will be established. This rotating brush 39 scrapes up dust from the floor surface and increases the efficiency of dust suction.

The circuit is shown in FIG. 8, and the electric blower 37 is controlled by a hand switch 36 and a phase control circuit 4o, and the electric motor 41 of the electric floor suction tool 35 is controlled by a switch 38. By changing the resistance value of the hand switch 36, the input to the electric blower 3 to the phase control circuit 4o is varied. When the switch 38 was closed, power was supplied to the electric motor 41, which rotated the rotating brush 39 of the electric floor suction tool 35.

FIG. 9 shows a diagram of the hand control unit. When you slide the hand switch 36, it starts at low mode and then goes to high mode. The sludge hand switch 36 and the rotary brush switch 38 are mechanically interlocked, and when the rotary brush switch 38 is turned on, the hand switch 36 slides and becomes weak. If the hand switch 36 is turned off while the rotating brush is on, the rotating brush will also be turned off.

Problems to be solved by the invention Conventional i! In the vacuum cleaner configuration, turning on the switch for the rotating brush of the electric floor suction tool causes the machine to run at low speed, and it is necessary to operate the hand switch again to set the frequently used input.

The present invention solves the above-mentioned conventional problems, and when the rotary brush switch is operated, automatic operation starts and the rotary brush is turned on.

Means for Solving the Problems In order to achieve the above object, the present invention is configured such that when a rotary brush switch is operated, automatic operation occurs and the rotary brush is turned on.

Effect: By using the means described above, it was possible to reduce the number of operations, obtain appropriate cleaning input, and improve cleaning performance.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

1 and 2, a hose 3, an extension pipe 4, and an electric floor suction device 5 are connected to a suction port 2 of a main body 1.

The rotating brush 9 of the electric floor suction tool 6 scrapes up dust from the floor surface and increases the efficiency of dust suction. A hand switch 6 is provided at the tip of the hose 3 to control an electric blower 7 disposed inside the main body 1. Next, the electric floor suction device 60 and rotating brush 8 are turned on and off near the hand switch 6.
A switch 8 for OFF is provided.

As shown in FIG. 3, a light emitting diode 10 is provided in a part of the air flow path 16 of the hose 3, and a light receiving section 11 is provided opposite to the light emitting diode 10. Changes in the amount of light are detected. The light emitting diode 10 and the light receiving section 11 form a dust sensor 17. Fourth
The circuit is shown in the figure, and the signal from the light receiving section 11 is amplified, waveform-shaped, and input to the microcomputer 12. The vacuum cleaner has two modes: an automatic operation mode in which the input to the electric blower 7 is controlled according to the amount of dust 16 detected by the dust sensor 17, and a manual mode in which the input is manually selected.

To explain the operation based on the above configuration, the rotary brush switch 8 is used to turn on/off the electric motor 13 when electric transmission is performed in automatic operation mode or manual operation mode, and when JiL machine 7 is in operation.
F is used to switch between the rotating brushes 9 and 9. If the switch 8 for the rotating brush is pressed while the rotating brush is stopped, the electric motor 13 is started and the rotating brush 9 is switched on.
When the machine rotates, it enters automatic operation mode. The automatic operation mode can be set to the user-friendly input/L' mode, and by pressing the rotary brush switch 8 once, the user can operate the motorized floor suction device at the appropriate input level and operate the rotary brush. can be operated, and the number of switch operations on the vacuum cleaner can be reduced. Among them, 7 and 13 are phase control circuits connected to the electric blower 7 and the electric motor 13, respectively.

Effects of the Invention As described above, according to the present invention, it is possible to provide a vacuum cleaner that reduces the number of operations, obtains appropriate cleaning input, and improves cleaning performance.
