Abstract

PROBLEM TO BE SOLVED: To provide a charging type electric vacuum cleaner in which when there exists fluctuation of charging batteries with electricity caused by imperfection of charging, it is informed by a displaying means and when individual batteries are charged, both charging batteries with electricity are always finished by full charging. SOLUTION: When the battery 13 or 23 is charged with electricity, it is connected with a discharge (refresh) circuit. A battery electric voltage detecting part 38 detects remaining amount of the battery by the terminal electric voltage of the battery 13 or 23. A control part 36 locks action of a charge driving part 37 from the detected electric voltage and outputs a action signal to a refresh driving part 40 to make it on and the battery is discharged (refreshed) to a definite value through the refresh part 39 consisting of a discharge resistance. As the result of discharging, when the same remaining amounts of the batteries are obtained, the control part 36 locks the action of the refresh driving part 40 and drives the charge driving part and the first battery 13 and the second battery 22 are started to be simultaneously charged with electricity from chargers 30b and 30c to make the charging time the same.

/ 28) and the like. This rechargeable vacuum cleaner has a configuration in which the electric current supplied from the charged storage battery is supplied to the electric blower to drive the electric blower, so that dust is sucked, so that a single charge can be used for a long time. Then, the storage battery had to be increased in size, the vacuum cleaner became heavy, the operability deteriorated, and the cost increased.

する構成が考えられる。Therefore, if the size of the storage battery or the size of the electric blower 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. In view of the above, it is necessary to reduce the size of the electric blower. However, if the electric blower is downsized, the suction power will be insufficient, so when cleaning a carpet with long hairs, the dust inside the carpet cannot be sufficiently sucked, and the dust remains on the carpet. In some cases. Therefore, a method of arranging a rotary brush driven by a motor on the floor suction device and efficiently sucking the dust while scraping out the dust on the floor surface by the rotary brush may be considered to compensate for the insufficient suction force. In addition, a dedicated storage battery is used for each of the electric blower and the motor so that the motor for driving the rotating brush can be driven by the storage battery in the same manner as the electric blower. Is conceivable in which a storage battery for driving the power supply is arranged in the floor suction tool.

えられる。In the electric vacuum cleaner having such a configuration, the battery of the vacuum cleaner main body and the storage battery of the floor suction device are connected in parallel to one charger and charged, or a dedicated charger is used for each. Charging may be considered, but a method of arranging charging completion display means such as an LED or a buzzer in the charger and notifying the user of the completion of charging to the user by charging completion display means or the like may be considered.

としての性能を十分に活用できないことがあった。For this reason, even if the display of the end of charge is made, it indicates whether the end of the charge of the storage battery for the vacuum cleaner body, the end of the charge of the storage battery for the floor suction tool, or both. Could not be determined to indicate the end of charging. If the battery for the vacuum cleaner has been charged but the storage battery for the floor suction device has not been charged, the user may remove the vacuum cleaner from the charger and use it. However, the storage battery for the floor suction tool became empty and the floor suction tool did not operate, so that the performance as a vacuum cleaner could not be fully utilized.

点があった。Further, when separate batteries are used for the vacuum cleaner main body and the floor suction device, there is a difference in the amount of use of both storage batteries depending on the condition of the floor surface, a notch used in the vacuum cleaner main body, and the like. . When these storage batteries having different remaining amounts are charged at the same time, the charging times are not the same, and a state occurs in which one of them is not fully charged. In particular, when using a nickel-cadmium battery, the battery life is longer when the battery is charged in a state where the remaining amount is small, and repeated charging in a state where the remaining amount is sufficient shortens the battery life. Then, by repeatedly charging the storage batteries having different charging start states as it is, there is a problem that the battery life of both batteries is different.
