Embodiment 1

[0023] Next, first pass Figure 1 to Figure 6 A description will be given of a power cord rewinding device equipped with the first embodiment of the present invention and an electric vacuum cleaner using the same.

[0024] exist figure 1 , 2 Among them, the electric vacuum cleaner body 1 (hereinafter referred to as the body) is slightly circular, and the lower part of the circular body 1 is provided with a scroll wheel 2 and a power cord rewinding device 3 . The scroll wheel 2 consists of a center wheel 4 that is positioned at the center of the circular body 1 and can rotate freely in the direction of travel, and 5 small rollers that are radially arranged around the center wheel 4 and can rotate freely through 360 degrees. In addition, the spring 6 exerts a downward force (that is, the direction of the rolling surface) on the center wheel 4 . The above-mentioned power cord rewinding device 3 is arranged above the scroll wheel 2 , and the power plug 7 is arranged at the rear...

Embodiment 2

[0033] next pass Figure 5 A second embodiment of the present invention will be described.

[0034] Such as Figure 5 As shown, the outer surface of the rotating body 19 is provided with a helical groove or protrusion 22 . In this way, when the power cord 16 is rewound when the cleaning operation is completed, the rotation of the rotating body 19 can be used to move the power cord 16 toward the inside (rewinding main body side), and when the power cord is pulled out, the power cord 16 can be sent out. , can play an auxiliary function for the movement of the power cord 16, thereby improving the convenience of use.

Embodiment 3

[0036] pass below Image 6 A third embodiment of the present invention will be described.

[0037] Such as Image 6As shown, the outer covering of the power cord 16 is provided with a small rib portion 23 along the length direction. In this way, during operation, the contact resistance between the power cord 16 and the bottom wall 14 of the rotating drum 13 can be reduced, and the torque required by the coil spring 21 to rewind the power cord 16 can also be reduced. At the same time, the pulling force when the power cord 16 is pulled out can be reduced correspondingly, so that the operability can be improved, and the mass and cost of the coil spring 21 can also be expected to be reduced.

[0038] To sum up, the power supply rewinding device for electric vacuum cleaners of the present invention can prevent overlapping / entanglement of power cords in the body of the vacuum cleaner, and the power cords can be pulled out / wound smoothly, thus making the electric vacuum cleaner mor...

Abstract

The present invention provides an electric vacuum cleaner capable of preventing the superposition of the power cord in the vacuum cleaner so that the vacuum cleaner is easy to use and the power cord can be smoothly winded and pulled out. The inventive vacuum cleaner is provided with a power cord winding device winding the power cord into a swirl shape segment. The power cord winding device includes: a coiler (20) for winding the power cord (16); a rotor drum (13), which is formed by disc-shaped floor and is located below the coiler for placing the winded power cord; and a rotary body (19) which is capable of freely rotating in the winding direction of the power cord and is provided on the opposite position of the rotor drum separated from the power cord. In this way, the self rigidity of the power cord winding device can be improved, the winding space of the power cord can be held constant, simultaneously the winding resistance force can be diminished by the rotary body to ensure that the winding of the power cord can smoothly carried out.

Description

technical field [0001] The invention relates to a power cord rewinding device and an electric vacuum cleaner using the device. Background technique [0002] The structure of this existing power cord rewinding device is that a disc-shaped upper wall and a lower wall are arranged on the upper and lower sides of the drum, and the upper wall and the lower wall rotate together to wind the power cord therebetween (one example can be Refer to Japanese Patent Laid-Open No. Sho 60-97177). [0003] However, in the above-mentioned power cord rewinding device, since the diameter of the drum is larger than that of the power cord used in household vacuum cleaners, the power cord cannot be smoothly rolled due to the influence of bending during molding and insufficient rigidity. around the problem. Contents of the invention [0004] The present invention aims to solve the above problems, and its purpose is to improve the rigidity of the power cord rewinding device itself, to ensure a ce...
