Abstract

PURPOSE:To prevent a power supply cord from being drawn in between the body of an electric cleaner and a rear wheel by making the rear wheel larger. CONSTITUTION:A cleaner body 1 and a rear wheel 3 with a larger diameter than the thickness of the body 1 are arranged and the outermost diameter surface of the rear wheel 3 is projected from the top and bottom surfaces and the rear side of the body 1 with the center of gravity of the body 1 positioned behind the shaft of the rear wheel 3. Here, an interval between the rear wheel 3 and the body 1 is made smaller than the diameter of a power supply cord 10 while a neck portion 11 is provided to the body 1 at a part facing the rear wheel 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner in which a power cord is not caught between a main body and a rear wheel.

[0002]

2. Description of the Related Art FIG. 2 is a Japanese Patent Application No.
In the electric vacuum cleaner described in the specification of No. 314156 (hereinafter, simply referred to as a vacuum cleaner), the diameter of the rear wheel 3 is made larger than the thickness T of the main body 1, and the outermost radial surface of the rear wheel 3 is the main body. Of the top surface 1a, bottom surface 1b and rear side surface 1c of
Further, the center of gravity of the main body 1 is arranged behind the axle 3a of the rear wheel 3. In this vacuum cleaner, since the center of gravity of the main body 1 is located behind the axle 3a of the rear wheel, the front part of the main body is separated from the floor surface 8 and floats freely when the hose 4 is not connected to the main body. As shown in FIG. 3, the cleaner body 1 is in a self-standing state with the connection portion 5 of the hose facing upward. As a result, this vacuum cleaner has low running resistance, high turning performance, and high operability, and is a convenient vacuum cleaner not only when cleaning the floor but also when cleaning high places such as the ceiling. ..

[0003]

In the above vacuum cleaner, as shown in FIG. 4, the shape of the main body 1 viewed from the rear is barrel-shaped, so that the rear wheel 3 and the main body 1 are separated from each other. In between
There is a gap in the shape of a letter. Therefore, if the power cord 10 is caught here during cleaning, the power cord 10 may be caught between the rear wheel 3 and the main body 1. Then, the rear wheel 3 does not rotate and the rear wheel is dragged, which causes a problem that the floor surface is scratched or the power cord is damaged.

The present invention has been made to solve the above problems, and the gap between the rear wheel and the main body is made smaller than the diameter of the power cord, and the main body is inclined so that the power cord is inclined. The purpose is to obtain a vacuum cleaner that does not get caught.

[0005]

An electric vacuum cleaner according to the present invention has a main body to which a hose, a hand pipe, an extension pipe, a floor brush, and the like are connected, as well as a blower motor and a dust bag, and a thickness of the main body. With a rear wheel with a large diameter, the outermost diameter surface of the rear wheel is projected from the top surface, bottom surface and rear side surface of the main body, and the center of gravity of the main body is positioned rearward of the wheel of the rear wheel. The gap is made smaller than the diameter of the power cord, and a constricted portion is provided at the peripheral end of the portion facing the rear wheel of the main body.

[0006]

According to the present invention, since the distance between the rear wheel and the main body is smaller than the diameter of the power cord, the power cord does not enter and the power cord is prevented by the constricted portion provided at the peripheral end of the portion facing the rear wheel of the main body. Escape from the rear wheel.

[0007]

【Example】

Example 1. FIG. 1 is a rear view with a part omitted showing an embodiment of the present invention. In the figure, the parts denoted by the same reference numerals as those in FIGS. 2 to 4 indicate the same parts, and G indicates the rear wheel 3 and the main body 1.
The distance from the case is smaller than the diameter of the power cord 10. Reference numeral 11 denotes a portion of the main body 1 facing the rear wheel of the case, which has a constricted peripheral edge, and will be referred to as a constricted portion.

Since the electric vacuum cleaner of the present invention is constructed as described above, even if the power cord 10 gets inside the rear wheel 3 during cleaning, the gap G is smaller than the diameter of the power cord 10, There is no narrowing between the case of the main body 1 and the rear wheel 3. Further, the power cord 10 slips on the slope of the constricted portion 11 as shown by an arrow 12 and escapes from the rear wheel 3 and is placed in the recess 13. Therefore, the power cord 10 is not caught between the case of the main body 1 and the rear wheel 3.

The length L of the constricted portion 11 is determined by the power cord 10.
The central portion 14 is thickened to obtain a volume for storing components, and the concave portion 13 is formed. Further, the constricted portion 11 may be provided in a portion of the portion facing the rear wheel 3 in which the main body 1 is shown by a chain line in FIG.
It does not necessarily have to be provided all around. In FIG. 2, a portion of the main body 1 protruding from the rear wheel 3 is provided with a cover for the rear wheel 3 on the main body 1 in consideration of design or the like. Does not occur.

[0010]

As described above, the present invention is provided with the cleaner body and the rear wheel having a diameter larger than the thickness of the body, and the outermost diameter surface of the rear wheel is projected from the top surface, the bottom surface and the rear side surface of the main body. When the center of gravity of the main body is positioned rearward of the axle of the rear wheel, the distance between the rear wheel and the main body should be smaller than the diameter of the power cord, and the neck of the main body case facing the rear wheel should be constricted. Since the portion is provided, the power cord escapes from the rear wheel along the slope of the neck portion. Therefore, there is an effect that the power cord is not caught in the rear wheel.
