Description

[Detailed description of the invention] Industrial applications The present invention relates to a rechargeable vacuum cleaner.

2. Description of the Related Art Conventional rechargeable vacuum cleaners generally have a configuration as shown in FIG. The configuration will be explained below according to the drawings.

In FIG. 3, 11 is an electric blower 12. switch 13
, a main body containing a secondary battery 14, etc.; 15 is a dust box detachably connected to the main body 11 via a buckle 16;
A suction port 17 is formed at the tip, and a filter 18 is provided inside. A handle 19 is also formed on the main body 1.

Problems to be Solved by the Invention In such a conventional rechargeable vacuum cleaner, the secondary battery 14 is located behind the electric blower 12 and almost directly below the handle 19, so it is difficult to hold the handle 19. When the main body 11 is placed horizontally. Also, suction port 1
7 is inclined as shown in the figure, so when cleaning, the lower end 17a of the suction port 17 touches the cleaning surface, and the tip 1
7b rises above the cleaning surface. Therefore, depending on the relationship between the position of the vacuum cleaner and the position of the cleaning surface, the position of holding the nozzle 19 must be changed so that the tip of the suction port 17 does not lift up. In the direction of lifting No. 11, the further back the center of gravity is, the greater the force applied to the hand becomes and the more fatigue the hand becomes. The second problem is that since the secondary battery 14 is located to the rear of the electric blower 12, it is not possible to provide a sufficient exhaust passage, resulting in a significant exhaust pressure loss and reducing suction performance. It was also a factor.

The present invention eliminates these conventional drawbacks and provides a rechargeable vacuum cleaner that is easy to use and has good performance.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention disposes a secondary battery in front of the electric blower and below the dust box.

Operation The present invention has the above-described configuration, and since the center of gravity is located further forward than when the battery is located at the rear or lower end of the electric blower, the burden of force on the hands during cleaning is reduced. Moreover, since there are no components behind the electric blower that would cause exhaust pressure loss, suction power performance is improved.

implementation row The implementation sequence will be explained below with reference to FIG.

In the figure, 1 is a main body, an electric blower 2 is inside, and a secondary battery 3 is placed at the front lower part of the electric blower 2. Switch 4 above
have. 5 is a dust box having a suction port 6 at its tip and a filter 7 inside;
The storage section for the secondary battery 3 is located below it. 8
9 is a buckle for detachably connecting the dust box 6 to the main body 1, and 9 is a handle formed on the upper part of the main body 1.

In the above configuration, since the secondary battery 3 is located in front of the electric blower 2, the center of gravity is further forward than in the conventional row, and therefore, the tip 6 of the suction port 6, which serves as a fulcrum during cleaning.
Since the distance to a is shortened, the force applied to the hand is reduced. Further, as shown in FIG. 2, an extension pipe 9 is connected to the suction port 6.
When used with an attachment such as the floor nozzle 10, the distance between the floor nozzle 10, which serves as a fulcrum, and the center of gravity becomes particularly long, so it is convenient to arrange the secondary battery 3 at the lower end of the dust box 6. This has a great effect on reducing the force applied to the Further, since there are no components other than an exhaust port (not shown) behind the electric blower 2, the exhaust pressure loss is small and the suction performance is improved.

Effects of the Invention As described above, according to the present invention, by arranging the secondary battery at the lower end of the dust box, the center of gravity is moved to the front, and the force exerted on the hands during cleaning is greatly reduced. Derani 2
Since there is no exhaust pressure loss due to the secondary battery, it exhibits effects such as improved suction performance.
