So by stronger power rotary turnplate 4, when electric wire 8b is wound, electric wire shortcoming chaotic or that swell laterally can take place when beginning to rotate.Originally strong revolving force is done the time spent, and electric wire 8b is subjected to strong tensile force, but the revolving force of rotating disk dies down after after a while, thereby causes the chaotic or situation of protuberance laterally of electric wire by the inertia force of the electric wire that twines.That is, there is the irregular shortcoming of electric wire that is wrapped on the rotating disk 4 in the above-mentioned prior art.
Above-mentioned shortcoming of the prior art comes down to can not to do movement at the uniform velocity by above-mentioned reel 4 and causes.That is, the strong elastic restoring force fast rotational that provides by spring 6 originally, but finally, the elastic restoring force of spring 6 dies down, and rotary speed is also slack-off.
Summary of the invention
In order to address the above problem, to the invention provides a kind of electric wire that makes and fitly to be wrapped in the cord-reel assembly of reel from the inside to surface.
To achieve these goals, the invention provides a kind of cord-reel assembly of vacuum cleaner, comprise framework, reel and spring, frame fixation is installed in the body interior of vacuum cleaner, reel is rotatable to be installed on the rotating shaft of said frame, can wound wire, the direction that spring is used for wound wire applies elastic force to reel, this spring is arranged on the medial surface of the winding part of wound wire on the reel and inserts between the internal diameter of back shaft of reel, has between medial surface and the spring the spring reel spring of resiliency supported to the inside.
The effect that the present invention brings is: when the elastic restoring force of reel spring worked, movement at the uniform velocity was almost done in the rotation of above-mentioned reel.More specifically, above-mentioned reel is almost done constant speed when rotation, be wrapped on the above-mentioned reel electric wire from interior do not begin to twine the shortcoming that electric wire ejects laterally or swells can take place.And, be wrapped in the from inside to outside neat winding of electric wire of cord-reel assembly according to the present invention.Electric wire twines explanation in order from the inboard to the outside can easierly draw electric wire, and then has improved the practicality of vacuum cleaner.
