Abstract

PURPOSE:To reduce the number of component parts and realize a low cost by setting a switch for connecting the low tension output section of a charging equipment for charging a storage battery, to the storage battery at the time of charging, and connecting said low tension output section to the driving motor of a power nozzle, to be switched at the time of using a commercial power source. CONSTITUTION:When a switch 4 is turned to a DC position in a state that a charging equipment 17 is removed from a main body 1, then the output of a storage battery 3 is connected to both the sides of the DC winding 15 of a fan motor MF2 and a power nozzle motor MP9, and a power nozzle 11 can be used in a cordless state. After that, when the charging equipment 11 is fitted on the main body 1 and a power cord 21 is connected to a plug socket and the switch 4 is turned to an AC position, then a power source is fed to the AC 100V winding 13 of the fan motor MF2, and at the same time, the DC low tension output section 20 of the charging equipment is connected to the power nozzle motor MP9, and voltage higher than the output voltage of the storage battery 3 by about 20% is fed, and the power nozzle 11 is strongly operated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a battery-powered vacuum cleaner having a power nozzle.

Conventional Technology There have been battery-powered vacuum cleaners with power nozzles. Then there was a battery-powered vacuum cleaner that could be used for both AC and DC power, with a switch that allowed you to select between commercial power supply and storage batteries.

Problems to be Solved by the Invention However, there has been a problem in that no AC/DC storage battery-powered vacuum cleaner with a power nozzle has been proposed. The present invention solves these problems and aims to provide a battery-powered vacuum cleaner that can be used for both AC and DC functions, and can drive a power nozzle both when using the storage battery and when using commercial power. It is.

Means for Solving the Problems In order to solve the above problems, the present invention switches the connection of the low-voltage output part of the charger that charges the storage battery to the storage battery when charging, and to the drive motor of the power nozzle when using commercial power. It is equipped with a switch.

Function: With this configuration, the vacuum cleaner of the present invention can drive the power nozzle both when using a commercial power supply and when using a storage battery.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4. 1 is a fan motor Mp2. It has a built-in storage battery 3 and a switch 4, and on its suction side, a dust collection case 7 having a built-in filter 5 and a suction port 6 at its tip is locked and fixed with a buckle 8. Further, a power nozzle motor Mp9 consisting of a DC commutator motor and a power nozzle 11 housing a flocked brush 10 driven by the motor are press-fitted into the suction port 6. The fan motor Mp2 has a commutator 12 and a winding 13 for the commercial power supply AC100V.
A DC commutator 14 and a winding 15 are provided.

The AC 100V winding 13 and the DC winding 15 are respectively wound around the core 16 in an overlapping state. Reference numeral 17 denotes a charger, in which a transformer 18 is provided, and the secondary side of the transformer 18 is connected to a DC low voltage output section 20 via a rectifying diode 19. Also, 21 is transformer 18
This is a power cord connected to the primary side of the AC output section 22 and the AC output section 22. Connectors 23 and 24 are provided on the rear surface of the main body 1 to connect with the DC low voltage output section 20 and the AC output section 22, and the charger 17 is configured to be detachable using a buckle (not shown).

FIG. 4 shows the operating contact portions corresponding to the charging (off), DC, and AC positions.

The switch 4 has three positions: OFF, charging, DC, and AC, and in the OFF and charging positions, the contact S1 is OFF.
It becomes N state and all other contact parts become OFF state. D
In C position, S4. When the contact part of Ss is in the ON state,
All other contact points are turned OFF. S in AC position
The contacts 2 and 83 are connected so that they are turned on and all others are turned off. Table 1 shows the above charging (off), DC,
ON and OFF of each contact at each position of AC
This is a list showing F states.

Below Margin In the above configuration, when the switch 4 is set to the DC position with the charger 17 removed from the main body 1, the output of the storage battery 3 is connected to both the DC winding 15 of the fan motor MF2 and the power nozzle motor Mp9. The power nozzle 11 can be used in a cordless state. Next, charger 17
When the power cord 21 is connected to the main body 1 and the power cord 21 is connected to the outlet, and the switch 4 is set to the AC position, power is supplied to the AC 100V winding 113 of the fan motor MF2, and at the same time, the DC low voltage output section 20 of the charger is is connected to the power nozzle motor Mp9, and the output voltage of the storage battery 3 is approximately 2
A 0% higher voltage is supplied and the power nozzle 11 is operated strongly. When charging the built-in storage battery 3 in the main body 1, turn off the switch 4 with the main body 1 attached to the charger 17 and set it to the charging position, the DC low voltage output part 20 is supplied to the charging control circuit, and the output of the circuit is used to Can be charged.

Effects of the Invention As described above, according to the present invention, a general DC commutator motor is used as a power nozzle motor, and the DC low voltage output of the charger can be outputted not only during DC operation but also during AC operation without using a dedicated circuit. It can be driven by sharing parts, and the effect is that the number of parts can be reduced and it can be realized at low cost. Furthermore, although this embodiment shows the case of AC/DC dual use, even in the case of DC only, the load on the storage battery 3 can be reduced by driving the power nozzle motor Mp9 using the DC low voltage output section 20 of the charger 7. There is also the effect that the usage time can be extended by reducing the amount of water used.
