There are things. BACKGROUND ART As an electric vacuum cleaner driven by a DC power source, there is conventionally known a vacuum cleaner main body provided with a storage battery for supplying electric power to both an electric blower and a motor of a rotary cleaning body.

As a storage battery provided in this electric vacuum cleaner, generally, a storage battery having a capacity suitable for the drive power of an electric blower, which requires a drive power larger than that of the motor of the rotary cleaning body, is selected. Therefore, electric power is supplied to the motor of the rotary cleaning body through the transformer.

When electric power is supplied through a transformer, not only the energy efficiency is lowered, but also the converted electric power becomes thermal energy and heat is generated in the vicinity of the transformer. Therefore, it is preferable that the electric blower and the motor of the rotary cleaning body are driven by the storage batteries having the capacities suitable for the respective driving powers.

Therefore, there is a demand for an electric vacuum cleaner provided with a first storage battery for supplying electric power to the electric blower and a second storage battery for supplying electric power to the motor of the rotary cleaning body. Vacuum cleaners are currently unknown.

[0006]

When the first storage battery for supplying electric power to the electric blower is provided and the second storage battery for supplying electric power to the motor of the rotary cleaning body is provided as described above, both storage batteries are provided. A charging control unit must be provided for each. However, this is not preferable because the number of components is inevitably increased.

[0007] The problem to be solved by the present invention is to obtain an electric vacuum cleaner in which the electric blower and the motor of the rotary cleaning body can be driven by the storage batteries having the capacities suitable for the electric blower and the charging controller. It is in.

[0008]

In order to solve the above problems, the present invention provides a first storage battery provided in a cleaner body for supplying electric power to an electric blower, and a rotary cleaning provided in a suction port body. A second storage battery that supplies power to the body can be electrically connected to each other, and a charging control unit that controls charging of both storage batteries is provided in the cleaner body or the suction port body.

In order to solve the above-mentioned problems, the present invention provides a charging stand to which a cleaner body and a suction body are detachably connected, respectively, to supply electric power to an electric blower provided in the cleaner body. A first storage battery and a second storage battery that is provided at the suction port and supplies electric power to the rotary cleaning body can be electrically connected to each other, and a charging control unit that controls charging of both storage batteries is provided. Then, the charging control unit controls the charging of the first storage battery when the cleaner body is connected to the charging stand, and charges the second storage battery when the suction port is connected to the charging stand. The control unit controls the charging of both storage batteries when at least the cleaner body is connected to the charging stand while the cleaner body and the suction port body are electrically connected.

A first storage battery 4 for supplying electric power to the electric blower 3,
A second storage battery 8 provided on the suction port body 6 having a rotary cleaning body 7 driven by a motor and supplying electric power to the rotary cleaning body 7 and a charging stand 60 are provided to charge the cleaner body 2 It controls the charging of the first storage battery 4 when it is connected to the stand 60, and controls the charging of the second storage battery 8 when the suction port body 6 is connected to the charging stand 60, and also the cleaner body. 2 and the suction port body 6 are electrically connected to each other, at least when the cleaner body 2 is connected to the charging base 60, the charging control unit 62 for controlling the charging of the two storage batteries 4, 8.
Since the motors of the electric blower 3 and the rotary cleaning body 7 can be driven by the storage batteries 4 and 8 having appropriate capacities, the charging control unit 62 can be shared.

Further, in the electric vacuum cleaner 1c, both the storage batteries 4 and 8 can be charged at the same time, or only the first storage battery 4 or the second storage battery 8 can be charged. Also,
Generally, even if you want to charge one of the storage batteries,
If the charging circuits of both storage batteries are closed at the same time, it takes longer time to charge than the case where only the charging circuits of the storage batteries to be charged are closed. This is because if the charging circuits of both storage batteries are simultaneously closed circuits, the voltage applied from the AC power source will be dispersed and the voltage applied to both storage batteries will be lower than the voltage applied from the AC power source, respectively. . Therefore,
In this electric vacuum cleaner 1c, the charging time can be shortened when only one of the storage batteries is charged.

Moreover, in this electric vacuum cleaner 1c, since the power supply circuit 61 and the power supply cord are provided on the charging stand 60, the weight of the cleaner main body 2 can be reduced.

In each embodiment, the engaging portion 41a
May be provided in the extension tube 12, or the terminal of the power receiving unit 40 may be a pin and the terminal of the power feeding unit 50 may be a female type. Further, a charging control unit may be provided in the suction port body, and the storage battery of the cleaner body and the storage battery of the suction port body may be charged by the charging control unit.

[0067]

According to the present invention, the electric blower and the motor of the rotary cleaning body can be driven by the storage batteries having suitable capacities, and the charge control section can be shared.
