Description

Electric vacuum cleaner {ELECTRIC CLEANER}

The present invention relates to a rechargeable vacuum cleaner with a built-in battery.

Background Art Conventionally, an electric vacuum cleaner for driving an electric blower by a storage battery is known from Japanese Patent Application Laid-Open No. 6-8852 (A47-L 9/28).

The rechargeable vacuum cleaner is configured to drive an electric blower to draw in dust and the like by supplying a current supplied from a charged battery to the electric blower. It must be enlarged, and the vacuum cleaner becomes heavy, resulting in poor operability and high cost.

Therefore, miniaturizing the storage battery with an emphasis on the operability and cost of the vacuum cleaner reduces the battery capacity of the storage battery and shortens the use time of the vacuum cleaner. Therefore, it is necessary to miniaturize the electric blower in consideration of the use time.

However, when the electric blower is downsized, the suction force is insufficient. Therefore, when cleaning the carpet, the dust of the carpet may not be sufficiently sucked, and the dust may remain in the carpet.

Therefore, a method of replenishing the insufficient suction force can be considered by providing a rotary brush driven by a motor at the suction port and efficiently sucking dust while sweeping dust on the floor surface by the rotary brush.

In addition, since the motor driving the rotary brush also needs to be driven by a battery as in the case of the electric blower, the dedicated battery is used for the electric blower and the motor, and the battery for driving the electric blower is placed on the cleaning body. At the same time as the installation, it is conceivable to install a storage battery for driving the motor at the suction port.

However, when cleaning long carpets or the like, or when the floor suction hole is strongly pushed onto the floor surface, the load on the motor increases, and the use time of the motor may be shorter than the use time of the electric blower. Since the suction force of the insufficient electric blower cannot be compensated for by the rotating brush, there arises a problem that the suction force decreases.

This invention is made | formed in view of the said fault, and makes it a subject to provide the vacuum cleaner which can prevent the fall of suction power, even if it uses a long carpet or the like for a long time.

Embodiments of the present invention will be described in detail below based on the drawings.

Reference numeral 1 denotes a cleaning main body, which has a dust collecting chamber 3 in which an inlet port 2 is formed in the front, and an electric blower storage chamber 5 in which the electric blower 4 is accommodated in the rear. Reference numeral 6 denotes a dust collecting bag accommodated in the dust collecting chamber 3 and mounted in a state in which an opening is communicated with the intake port 2, and reference numeral 7 denotes a dust collecting lid that closes and opens the upper surface opening of the dust collecting chamber 3. .

Reference numeral 8 is a front cover attached to the front surface of the dust collecting chamber 3, and forms a connecting cylindrical portion 9 communicating with the intake port 2, and the flexible hose (to be described later) is described later. One end of 15) is detachably mounted.

Reference numeral 10 denotes a caster roller installed at the front of the bottom surface of the basic vacuum cleaner 1, and reference numeral 11 denotes a pair of rear wheels rotatably installed on the rear side surface of the basic vacuum cleaner 1.

Reference numeral 12 is a cover which is attached to the lower part of the electric blower storage chamber 5 and constitutes a part of the lower surface of the cleaning main body 1, and the electric blower 4 is connected to the electric blower 4 between the bottom wall of the electric blower storage chamber 5. An accommodating part 14 for accommodating the first storage battery 13 for supplying the battery is formed. Reference numeral 15 denotes a flexible hose which is detachably connected to the inlet port 2 by inserting the connecting tube 16 formed at one end into the connecting cylindrical portion 9 of the cleaning base 1. The extension tube 17 and the floor suction opening 18 are detachably connected in order to the other end of the (). Reference numeral 19 is a handle formed integrally with the connecting pipe 16 of the flexible hose 15, and is located on the upper surface side of the cleaning main body 1 when the flexible hose 15 is connected to the cleaning main body 1. It is supposed to be.

Reference numeral 20 is a rotary brush rotatably provided in the floor suction opening 18, and is connected to the motor 21 via a drive transmission means (not shown). Reference numeral 22 is a second storage battery which supplies a current to the motor.

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

Numeral 23 denotes a charging station including a charger composed of a transformer (not shown) and a charging control circuit, and has a charging terminal (not shown).

In this configuration, when the vacuum cleaner is not used, the cleaning main body 1 is mounted on the charging base 23 while the rear surface of the cleaning main body 1 faces downward while the floor suction port 18 is mounted. The intake port 18 is mounted on the charging table 23 and stored therein. At this time, the charging terminals (not shown) provided in the charging base 23 contact the charging receiving units not shown in the rear surface of the cleaning body 1 and the floor suction port 18, respectively, The built-in first storage battery 13 and the second storage battery 22 built in the floor suction port 18 are charged.

When cleaning, for example, when the floor surface is a carpet or the like, the rotating brush 20 is rotated by driving the motor 21, and the dust in the carpet is swept away by the rotating brush 20 to suck in dust.

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

Therefore, when cleaning the long carpet or the like or cleaning by pushing the floor suction opening 18 strongly to the floor surface, the load of the motor 21 is increased, and the use time of the motor 21 is increased by the electric blower 4. The drawback that occurs when the use time is shorter, that is, the suction force of the insufficient electric blower 4 cannot be compensated by the rotating brush 20, and the drawback that the suction force decreases can be solved.

In addition, in the present embodiment, the first storage battery 13 is installed in the cleaning main body 1, and the second storage battery 22 is installed in the floor suction opening 18, whereby the electric blower 4 and While the primary battery 13 can be installed in close proximity, the motor 21 and the secondary battery 22 can be installed in close proximity, and the wiring between the electric blower 4 and the primary battery 13 can be simplified. In addition, the wiring between the motor 21 and the second storage battery 22 can be simplified.

Further, the first storage battery 13 and the second storage battery 22 may be provided together with the cleaning main body 1, and the floor storage suction opening 18 can be reduced in weight, and the floor suction opening ( 18) usability can be improved.

In addition, in this embodiment, the continuous use time of the motor 21 by the second storage battery 22 when cleaning the carpet is more than the continuous use time of the electric blower 4 by the first storage battery 13. Although it is set to become long, the continuous use time of the motor 21 by the 2nd storage battery 22 when cleaning other conditions, for example, floor cleaning, tatami cleaning, or a carpet, a floor, and a tatami, You may set so that it may become longer than the continuous use time of the electric blower 4 by the single storage battery 13.

According to the configuration of claim 1 of the present invention, the motor during driving of the electric blower is set by setting the continuous use time of the motor from full charge of the second battery longer than the continuous use time of the electric blower from full charge of the first battery. Without stopping the motor, the drawback caused by the motor stopping during the operation of the electric blower, that is, the suction force of the insufficient electric blower cannot be compensated by the rotating brush, and the suction force can be prevented from decreasing.
