The storage battery 16 is accommodated in a position corresponding to.
[0014]
17 is a center of gravity position of the storage battery 16, and the center of gravity position 17 of the storage battery 16 is in a use state of the cleaner body 1, that is, in a state where the caster roller 11 and the rear wheel 12 of the cleaner body 1 are grounded to the floor surface. It arrange | positions ahead and downward rather than the gravity center position 13 of the cleaner body 1 except the storage battery 16.
[0015]
A conductive terminal plate 18 is disposed on the rear surface of the cleaner body 1, and the terminal plate 18 is connected to the storage battery 16.
[0016]
Reference numeral 19 denotes a flexible hose that is inserted into the connecting tube portion 10 of the cleaner body 1 and is detachably connected to the air inlet 2, and the other end of the flexible hose 19. The extension pipe 21 and the floor suction tool 22 are detachably connected to each other. A handle 23 is formed integrally with the connecting pipe 20 of the flexible hose 19 and is positioned on the upper surface side of the cleaner body 1 when the flexible hose 19 is connected to the cleaner body 1. ing.
[0017]
Reference numeral 24 denotes a charging stand having a built-in charger comprising a transformer and a charging control circuit (not shown), and has a mounting portion 25 for mounting the rear surface of the cleaner body 1 in an upright state.
[0018]
Reference numeral 26 denotes a terminal housing portion formed at a position corresponding to the terminal plate 18 of the cleaner body 1 of the charging base 24. The terminal housing portion 26 incorporates a conductive leaf spring 27 serving as a charging terminal. The spring 27 is connected to a built-in charger. Reference numeral 28 denotes a slit formed in the terminal housing portion 26. When the cleaner body 1 is placed on the charging base 24, the terminal plate 18 of the cleaner body 1 is inserted into the slit 28 to the leaf spring 27. It comes to be elastic.
[0019]
29 and 30 are guide walls formed on two opposite sides of the mounting portion 25, and when the cleaner body 1 is placed on the placement portion 25, the upper and lower surfaces of the cleaner body 1 are The guide walls 29 and 30 are opposed to each other.
[0020]
The guide walls 29 and 30 are formed so as to be gradually inclined from the upper end toward the placing portion 25 toward the mounting portion 25. When the cleaner body 1 is placed on the charging base 24, the guide walls 29 and 30 are cleaned. The machine body 1 is guided to a proper position so that the terminal plate 18 of the cleaner body 1 and the leaf spring 27 of the charging stand 24 are surely matched.
[0021]
In this configuration, when the vacuum cleaner is not used, the vacuum cleaner body 1 is placed and stored on the placement portion 25 of the charging stand 24 with the rear surface of the cleaner body 1 facing downward. At this time, the terminal plate 18 provided on the rear surface of the cleaner body 1 is brought into elastic contact with the leaf spring 27 through the slit 28 of the terminal housing portion 26, and the storage battery 16 built in the cleaner body 1 is charged.
[0022]
When cleaning, the cleaner main body 1 is removed from the charging stand 24, and one end of the flexible hose 19 is connected to the air inlet 2 of the cleaner main body 1 as shown in FIG. The extension pipe 21 and the floor suction tool 22 are sequentially connected to the other end of the wheel, and the caster roller 11 and the rear wheel 12 are moved and used in contact with the floor surface.
[0023]
Since the center of gravity 16 of the storage battery 15 is disposed in front of the center of gravity 13 of the cleaner body 1 excluding the storage battery 16, the center of gravity is located in front of the cleaner body 1 when the storage battery 16 is attached to the cleaner body 1. Therefore, even if the flexible hose 19 is pulled along with the cleaning operation, the front of the cleaner body 1 is not easily lifted up, and the cleaner body 1 does not fall down. Will improve.
[0024]
Further, since the center of gravity 17 of the storage battery 16 is located below the center of gravity of the cleaner body 1, the center of gravity of the cleaner body 1 moves downward while the storage battery 16 is attached to the cleaner body 1, and cleaning is performed. The machine body 1 is less likely to fall, and the running stability is improved.
[0025]
【The invention's effect】
According to claim 1 of the present invention, the center of gravity of the storage battery is arranged in front of the center of gravity of the cleaner body excluding the storage battery, so that the center of gravity is placed in front of the cleaner body when the storage battery is mounted on the cleaner body. Even if the flexible hose is moved along with the cleaning operation, the front of the cleaner body is not easily lifted up, and the tip of the cleaner body can be prevented from being overturned and the operability and usability can be improved.
[0026]
According to claim 2 of the present invention, the center of gravity of the storage battery is disposed in front of and below the center of gravity of the vacuum cleaner main body excluding the storage battery, so that the front of the vacuum cleaner main body is attached to the vacuum cleaner main body. Even if the center of gravity moves and the flexible hose is pulled along with the cleaning operation, the front of the vacuum cleaner body is not easily lifted up, and the vacuum cleaner body can be prevented from falling, improving operability and usability. The center of gravity of the cleaner body can be moved downward to prevent the cleaner body from overturning, and the running stability can be improved.
