DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rechargeable vacuum cleaner having a built-in storage battery.

[0002]

2. Description of the Related Art Conventionally, a vacuum cleaner for driving an electric blower by a storage battery is disclosed in Japanese Utility Model Publication No. 6-8852 (A47).
L 9/28).

[0003] This rechargeable vacuum cleaner has a configuration in which a current supplied from a charged storage battery is supplied to an electric blower to drive the electric blower to suck dust and the like. If the battery can be used for a long time, the size of the storage battery must be increased, the vacuum cleaner becomes heavy, the operability is deteriorated, and the cost is increased.

Therefore, when the size of the storage battery is reduced with emphasis on the operability and cost of the vacuum cleaner, the battery capacity of the storage battery is reduced and the usage time of the vacuum cleaner is shortened. Needs to be reduced in size.

However, when the size of the electric blower is reduced, the suction power becomes insufficient.
There is a case where dust in the back of the carpet cannot be sufficiently sucked, and the dust remains in the carpet.

Therefore, a method of compensating for the insufficient suction force by arranging a rotary brush driven by a motor on the suction tool and efficiently sucking the dust while scraping out the dust on the floor surface by the rotary brush is considered. Can be

[0007] In addition, with the above configuration, the motor for driving the rotating brush must be driven by a storage battery as in the case of the electric blower. Therefore, a dedicated storage battery is used for each of the electric blower and the motor, and the motor blower is used. A configuration is conceivable in which a storage battery to be driven is provided in the cleaner body and a storage battery to drive the motor is provided in the suction tool.

However, the load on the electric blower may be increased due to clogging of the dust collecting portion of the cleaner body or clogging of the hose, and the use time of the electric blower may be shorter than the use time of the motor. However, in this case, even if the dust on the carpet or the like is scraped out by the rotating brush, there is a problem that the scraped-out dust cannot be sucked in by the electric blower.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and has as its object to provide a vacuum cleaner capable of preventing the occurrence of inconveniences such as the inability to suck in the scraped-out dust. Make it an issue.

For storing the first storage battery 13 for supplying current to the storage unit 1
4 are formed. Reference numeral 15 denotes a connecting pipe 16 formed at one end.
The flexible hose 1 is inserted into the connection cylinder 9 of the cleaner body 1 and detachably connected to the suction port 2.
An extension pipe 17 and a floor suction tool 18 are sequentially and detachably connected to the other end of 5. Reference numeral 19 denotes a handle integrally formed with the connection pipe 16 of the flexible hose 15, which is located on the upper surface of the cleaner main body 1 when the flexible hose 15 is connected to the cleaner main body 1. ing.

Reference numeral 20 denotes a rotary brush rotatably disposed on the floor suction tool 18, which is connected to a motor 21 via drive transmission means (not shown). Reference numeral 22 denotes a second storage battery that supplies a current to the motor.

The first storage battery 13 and the second storage battery 2
When the carpet is in a fully charged state, the continuous use time of the electric blower 4 by the first storage battery 13 when cleaning the carpet is the second time.
The first storage battery 13 is mounted so as to be longer than the continuous use time of the motor 21 by the storage battery 22.

Reference numeral 23 denotes a charging stand incorporating a charger including a transformer and a charging control circuit (not shown), and has a charging terminal (not shown).

In this configuration, when the cleaner is not used, the cleaner main body 1 is placed on the charging stand 23 with the rear surface of the cleaner main body 1 facing downward with the floor suction tool 18 attached, and The suction tool 18 is placed on the charging stand 23 and stored.

In cleaning, for example, when the floor surface is a carpet or the like, the motor 21 is driven to rotate the rotary rotating brush 20, and the dust inside the carpet is scraped out by the rotating brush 20 to suck in the dust.

In the present invention, the continuous use time of the electric blower 4 by the first storage battery 13 is set longer than the continuous use time of the motor 21 by the second storage battery 22.

Therefore, when the load on the electric blower 4 is increased due to clogging of the dust collecting bag 6 or clogging of the flexible hose 15, the use time of the electric blower 4 becomes shorter than the use time of the motor 21. In other words, it is possible to eliminate the inconvenience that the dust blown out by the electric blower 4 cannot be sucked in even if the dust on the carpet is scraped out by the rotating brush.

In the present embodiment, the first storage battery 13 is provided in the cleaner main body 1 and the second storage battery 22 is provided in the floor suction tool 18, so that the electric blower 4 The first storage battery 13 can be arranged close to the first storage battery 13, and the motor 21 and the second storage battery 22 can be arranged close to each other, so that the wiring between the electric blower 4 and the first storage battery 13 can be arranged. Can be simplified, and the wiring between the motor 21 and the second storage battery 22 can be simplified.

The first storage battery 13 and the second storage battery 2
2 may be arranged on the cleaner body 1 together.
With this configuration, the floor suction tool 18 can be reduced in weight, and the usability of the floor suction tool 18 can be improved.

Further, in this embodiment, the continuous use time of the electric blower 4 by the first storage battery 13 when cleaning the carpet is longer than the continuous use time of the motor 21 by the second storage battery 22. , But other conditions,
For example, when the floor is cleaned, the tatami is cleaned, or the carpet, the floor and the tatami are cleaned, the continuous use time of the electric blower 4 by the first storage battery 13 is changed by the motor 2 by the second storage battery 22.
It may be set to be longer than one continuous use time.

[0029]

According to the configuration of claim 1 of the present invention, the first
The continuous use time of the electric blower from the full charge of the storage battery
By setting longer than the continuous use time of the motor from the full charge of the second storage battery, when the dust of the carpet is being scraped out by the rotating brush, an inconvenience due to the stop of the electric blower, that is, the carpet etc. by the rotating brush Even if the dust is scraped out, it is possible to prevent the occurrence of inconveniences such as the inability to suck in the dust scraped out by the electric blower, and to provide effects such as improvement in usability.

According to the configuration of the second aspect of the present invention, since the main body of the cleaner and the first storage battery can be arranged close to each other, the wiring between the electric blower and the first storage battery can be simplified. Therefore, there is an effect that the assembling workability can be improved.
