Abstract

PROBLEM TO BE SOLVED: To provide a charging type electric vacuum cleaner in which loss of a battery for suction tool for a floor is decreased and a rotating brush is prevented from running away. SOLUTION: In figure 6 (A), as a floor face roller 29 is not brought into contact with the floor face, a floor face detecting switch 28 for detecting that the suction tool 20 is placed on the floor face has no possibility of feeding a driving electric current to a motor 22 through a main switch from the battery. Then, under a condition where the suction tool 20 for the floor is brought into contact with the floor face, as shown in figure 6 (B), it becomes to a condition where the driving electric current can be fed to the motor 22 through the main switch from the battery 23. Under a condition where the main switch is on and the suction tool 20 for the floor is moved back and forth, the back wheels 25 are rotated accompanied with it and only when rotation of the back wheels 25 is detected by means of a lead switch 27 disposed at a position facing to a magnet 26, the driving electric current is fed to the motor 22 from the battery 23.

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 in which an electric blower is driven by a storage battery is disclosed in Japanese Utility Model Publication No. 6-8852 (A47L9).
/ 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.

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.

[0004]

In the vacuum cleaner having such a configuration, the rotary brush is driven by the rotary brush drive switch regardless of the movement of the floor suction tool, so that the cleaning operation is not performed. In other words, since the power supply of the rotating brush is turned on even when the floor suction tool does not move, the storage battery loses much power, and the remaining amount of charge may quickly run out. Further, the rotary brush of the floor suction device is operated only by touching the rotary brush drive switch, which is dangerous. Therefore, an object of the present invention is to provide a rechargeable vacuum cleaner in which loss of a storage battery of a floor suction tool is reduced and unnecessary operation of a rotating brush is prevented.
