Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner having a cord reel device.

BACKGROUND ART Conventionally, this type of vacuum cleaner generally had the following configuration. The configuration will be described below with reference to the drawings.

In FIGS. 4 and 5, 1 is a vacuum cleaner body with a built-in electric blower 2, and 3 is a dust collection box for collecting dust. 4 is a cord reel for winding the cord 5, and a cord reel shaft 6
It is rotatably supported. 7 is a spiral spring that urges the cord reel 4 in the direction to wind up the cord 5;
A brake lever 8 has a brake body made of rubber at one end and is biased by a spring so as to press the brake body against the flange surface of the cord reel 4.

9 is a main body switch that turns on and off the electric blower.

Problems to be Solved by the Invention In such a conventional vacuum cleaner, the cord 5 can be easily wound by operating the brake lever 8.
However, as shown in Fig. 5, the user has to pull the cord 6, which is many meters long, by hand, which is time-consuming and requires a lot of effort. I had a problem where my whole arm, especially my palm, started to hurt after I pulled it out several times.

The present invention solves these conventional problems and provides a vacuum cleaner that is more convenient to use.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a drive shaft for pulling out the cord at the cord outlet and links this drive shaft to a motor powered by a battery.

Function: With the above configuration, the drive shaft that clamps the cord can be rotated by the motor.

Just by operating a switch, the cord can be pulled out easily and quickly.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 3, 10 is a vacuum cleaner body equipped with an electric blower and a cord reel device for winding up the cord 11, and a cord outlet 12 is formed at the rear for moving the cord 11 in and out. . A rotary shaft 1 is provided in the cord outlet 12 so as to hold the cord 11 therebetween.
3 and a drive shaft 14 are disposed, and the rotating shaft 13 is pivotally supported so as to be slidable in the vertical direction and rotatable. 15 is a spring that biases the rotating shaft 13 in the direction of pressing against the cord 11;
16 slides the rotating shaft 13 and the spring 16 upward to rotate the rotating shaft 1.
3 from the cord 11, and is rotatably supported approximately at the center. 17 is a brake button that presses the brake lever 16 from the outside. Further, the drive shaft 14 is connected to the small gear 1B via a small gear coaxially provided, and the small gear 18 is activated by the small gear 2o via a large gear 19 provided coaxially. moreover.

This small gear 2o is connected to the large gear 21 coaxially,
It is started by the motor 22. The motor 22 is a DC motor, and a rechargeable lead battery 23 and a charging circuit 24 are built into the vacuum cleaner body 1o. Reference numeral 25 is a lead for the cord 11 that turns the motor 22 on and off, and 26 is a changeover switch that turns the cleaner body 10 and the charging circuit 24 on and off. FIG. 3 shows a specific circuit configuration of this embodiment, in which 27 is a transformer, 28 is a rectifying diode, 29 is a thyristor for controlling charging current, 3o and 31 are a constant voltage diode and thyristor for detecting the completion of charging, 32
33 is a resistor for current limiting, and a diode for preventing backflow. 34 is a lid for attaching and detaching the lead battery.

To explain the operation in the above configuration, the drawer button 26
By pressing , the motor 22 rotates.

The rotation speed of the shaft of each gear is gradually reduced by the combination of large and small gears, and torque that overcomes the torque of the spiral spring is transmitted to the drive shaft 14.
4, the cord 11 is pulled out. Further, by incorporating the lead battery 23 and the charging circuit 24 into the cleaner main body 1o, it is possible to eliminate the need to replace the battery, thereby improving usability.

Effects of the Invention As is clear from the embodiments described above, the vacuum cleaner of the present invention is provided with a drive shaft that clamps the cord at the cord outlet, and this drive shaft is rotated by a motor via a speed reduction device consisting of gears. This eliminates the need for the trouble and effort of pulling out the cord, and by incorporating a rechargeable battery such as a lead battery and a charging circuit inside the vacuum cleaner as a power source for the motor, there is no need to replace the battery. This will greatly improve usability.
