Abstract
In an engine drive washing machine, a discharge switch 10 is provided in a jet gun 5. When the switch 10 is turned off, an engine 1 is stopped. When the switch 10 is turned on, the engine 1 is started up to drive a pump 2. When an outlet pressure of the pump 2 is not lower than a predetermined value, a water-discharge valve in the gun 5 is opened to cause the water to be discharged. When the switch 10 is not turned off for a long time, the engine 1 is stopped. When an operator takes up the gun 5 to start the operation, the engine 1 is started up. The engine-drive type of washing machine is provided with a battery 13 for a starter motor, and the battery 13 is charged by a generator function of a starter-motor generator 3 during the operation of the engine 1.
