きる。Operation With the configuration described above, the electric blower can be driven at the time of AC input, and at this time, when the switch is operated, the light of the light emitting element is received by the light receiving element to operate the phase control circuit, and the electric blower enters the operating state. On the other hand, another light receiving element also receives this light, and power is supplied from the secondary battery to the self-propelled control circuit by the output of this light-receiving element, and the self-propelled electric motor is driven to make the cleaner self-propelled. Also, when the AC power is not applied, the electric blower can be driven by the secondary battery. At this time, by operating the switch, the electric blower and the self-propelled electric motor can be driven as in the AC mode. The operation function and self-propelled function of the vacuum cleaner can be obtained. Thus, the operation and the stop of the electric blower and the self-propelled electric motor can be started and stopped both by AC / DC with one set of switches, and the switching can be performed while maintaining the insulation by using the optical element.

本体を持ち運ぶといったわずらわしさが解消される。Further, when both ends of the constant voltage element are short-circuited by the switching operation of the changeover switch, the light emitting element emits light, the light is received by the light receiving element, the phase control circuit is operated, and the electric blower is driven. Electric power is supplied from the secondary battery, and the self-propelled motor is driven by the self-propelled control circuit. When both ends of the constant voltage element are opened by the switching operation of the changeover switch, the voltage applied to the light emitting element decreases by the set voltage of the constant voltage element, the light emitting element does not emit light, and the electric blower stops. The self-propelled motor is supplied with electric power from a secondary battery and is driven by a self-propelled control circuit. Therefore, even when the electric blower is stopped, only the self-propelled function can be operated independently, and the trouble of carrying the cleaner main body, such as when moving between rooms or storing, is eliminated.

止される。Further, when both ends of the constant voltage element are short-circuited by the switching operation of the changeover switch, the electric blower is in an operating state due to the light of the light emitting element. When the set voltage of the voltage element is reached, the light emitting element is turned off, the electric blower is stopped, and the light emitting element is held in the off state by the latch means. Therefore, for example, in the DC mode, when the secondary battery is exhausted, the load is automatically cut off, and overdischarge of the secondary battery is prevented.
さらに、切替スイッチの切替操作により、定電圧素子

がって、電動送風機運転中は自走用電動機をゆっくり働
かせ、電動送風機停止中は自走用電動機を早く働かせる
ことができる。Further, when both ends of the constant-voltage element are short-circuited by the switching operation of the changeover switch, the light-emitting element emits light, the electric blower enters an operating state, and the self-propelled motor is current-limited by a resistance. The movement speed becomes slow. Also,
Since the light emitting element does not emit light at the same time when both ends of the constant voltage element are opened by the switching operation of the changeover switch, the operation of the electric blower is stopped, and the current limiting resistance of the self-propelled motor is short-circuited by the short-circuit means. The voltage of the secondary battery is directly applied to the running motor, and the speed of the self-running is increased. Therefore, the self-propelled electric motor can be operated slowly while the electric blower is operating, and the self-propelled electric motor can be operated quickly while the electric blower is stopped.

Then, an electric current flows through the light emitting element 42, and the cleaner enters an operating state. Further, in this state, when the secondary battery 35 is consumed and the terminal voltage decreases and falls to a voltage set by the Zener diode 40, the transistor 44 is turned off. At this time, a gate current flows through the gate of the thyristor 54 to turn it on. Then, transistor 44
Keeps the OFF state, and the vacuum cleaner keeps the operation stopped.
