Problems solved by technology

[0002] Now household appliances have been popularized in every household, but the household appliances on the market can only work with AC or DC. For example, vacuum cleaners can only use AC or DC. ; These two kinds of power supply all have the inconvenience of actual use: can only use AC household appliances, such as vacuum cleaners: it can only be used in places with AC power, which brings inconvenience to the family, such as power outages, AC power failure in the family, etc. Unusable places; household appliances that can only use direct current: its working time is limited, when it is used for home work, it suddenly runs out of power or forgets to charge it when it is in use, or the home work is only partially done It was out of power, which made homework extremely inconvenient

Embodiment 1

[0017] Such as Figures 1 to 3 As shown, the AC-DC dual-purpose motor control system is composed of an AC-DC dual-purpose motor and a control circuit, wherein the AC-DC dual-purpose motor includes a casing 18, a stator part and a rotor part 1 inside the casing 18, and the casing 18 is Assembled structure, the rotor part 1 has an AC armature winding for alternating current and a DC armature winding for direct current, the AC armature winding has an AC armature winding commutator 2, and the DC armature winding has a DC armature winding commutator 3, The AC armature winding commutator 2 and the DC armature winding commutator 3 are respectively located at both ends of the rotor part 1, and the output end 19 of the rotor part 1 protrudes from the DC armature winding commutator 3 outside the casing 18, and the alternating current The armature winding commutator 2 cooperates with brush I4 and brush II5, the DC armature winding commutator 3 cooperates with brush III6 and brush IV7, an...

Embodiment 2

[0021] A household appliance has an AC / DC motor for power output, wherein the control system of the AC / DC motor adopts the aforementioned AC / DC motor control system. Such as Figure 4 Shown is a schematic diagram of the structure when the household appliance is a vacuum cleaner. It is composed of a supporting shell 24 and a working head 25. The AC and DC motor constitutes its power part, and the rotation of the AC and DC motor drives the working head to work. Due to the convenient conversion of AC and DC, the vacuum cleaner is very convenient to use.

Abstract

The invention provides an AC-DC-two-purpose-motor control system which is simple in structure, small in occupied space, and convenient in AC-DC control conversion and a household appliance which is convenient for domestic use. The AC-DC-two-purpose-motor control system includes an AC-DC two-purpose motor and a control circuit. A rotor part of the AC-DC two-purpose motor includes an AC armature winding with an AC-armature-winding commutator and a DC armature winding with a DC-armature-winding commutator. The AC-armature-winding commutator is in cooperation with an electric brush I and an electric brush II. The DC-armature-winding commutator is in cooperation with an electric brush III and an electric brush IV. The control circuit includes an AC power supplying end I, an AC power supplying end II, a DC power supplying end I, a DC power supplying end II, a diode I, a diode II, a diode III, a diode IV and a relay. The relay is provided with a coil, a contact I and a contact II.
