Abstract

PURPOSE:To provide a vacuum cleaner capable of drawing out a power cord smoothly and having a small compact intake port body by providing on a handle an engaging means for stopping the power cord from being moved in the direction of being wound in the cord reel side and a button for releasing such engagement. CONSTITUTION:When a plug 49 is drawn out to connect a power cord 21 to a plug socket, a cord reel 15 is rotated to draw out the power cord 21. Rotational energy is stored on a coil spring 23 to generated a force for rewinding the power cord 21. However, the power cord 21 is sandwiched and held between a brake surface 48 of a brake lever 45 urged by a spring 47 and a rotatable roller 42. When a vacuum cleaner is stored after cleaning, the plug 49 is removed from the plug socket. When a button 44 is depressed, the brake lever 45 is pivoted about a shaft 46 to separate the brake surface 48 from the power cord 21 so that the power cord 21 is wound around the cord reel 15 by the rotational energy stored in the spring 23. A plug 50 is stopped at the inlet of a hole 36 formed in a handle 35.

Problems to be Solved by the Invention However, in conventional vacuum cleaners, when using the power cord 5, the power cord 5t is pulled out from the hook 7, and when the power cord 5 is stored after use, the power cord 5 is hooked again. The process of winding it around the part 7 had to be noisy, making it inconvenient to use. In addition, since the power cord 5 is sharply bent at the hook 7, there is a problem in that the durability against disconnection of the power cord is significantly reduced. Since the power cords 5 are around, there is a problem that if the power cords 5 cross each other during cleaning, the power cords 5 may get caught on obstacles and damage the power cords 5.
o Furthermore, there is a cord inside the suction port body 1 so that the power cord can be completely wound up! It is conceivable to incorporate the J-1vi, but simply incorporating the Cordry/L' causes the problems that the power cord cannot be pulled out smoothly and the suction port body becomes too large and difficult to handle.

The present invention solves these problems, and allows the power cord to be easily pulled out and stored without the need to unwind the power cord from the hook or to adjust the winding, as in the conventional method. It eliminates problems such as the power cord getting caught on obstacles and getting damaged, improves the power cord's durability against bending, and even allows the power cord to be pulled out. Do it smoothly, suck 1. A, B The purpose is to make the main body small and compact.

tth Means for Solving Section M To solve this problem, the present invention generates a suction force in the suction port body in which the suction port is formed at the lower end! ! , it has a built-in blower and cordry 1 for winding up the power cord, and is also equipped with a dust collection section for collecting dust, and a rod-shaped hollow handle is connected to the suction port body, and a hollow handle is provided at the tip of the handle. A power cord is inserted into the inside of these handles and the handle, and a 7t7'' lug is provided at the tip of the power cord so as to protrude from the end of the handle, and the power cord is wound around the handle in the direction of the cord reel. It is equipped with a locking means for stopping the movement and a lead part for releasing the lock. Furthermore, the present invention incorporates a cordry for winding up the power cord in the center of the suction port body with a suction port formed at the lower end, and an electric blower that generates suction force on one side of the cordry μ. Built-in,
Further, a dust collecting section is formed on the other side of the cord reel, the cord reel is supported by being built into a hollow bearing, and the entire bearing is used as a suction passage to communicate the dust collecting section with the electric blower. .

Function This configuration requires a power supply coat (f) for cleaning.
To connect to a power outlet, pull the plug and pull out the power cord.When storing after cleaning, press the lead part to release the lock and the power cord will automatically reel. It is wound up.

Therefore, usability is improved compared to the conventional power cord in which the entire power cord is pulled back and wrapped around the hook. There may be electricity around the inlet body or handle.

Since there is no power cord and it is neat, there is no chance of the power cord getting caught on obstacles during cleaning and causing damage. The power cord does not have to be bent sharply, and the durability against bending of the power cord is improved.

Furthermore, since the cord reel is placed in the center of the entire suction port body and the power cord is pulled out from the cord reel, the power cord can be pulled out smoothly.
