16 is attached. The inlet of the water conduit 16 is opened on the upper surface and faces the water inlet 18 opened at the bottom of the detachable tank 17 and is sealed and coupled by a packing 19. Reference numeral 20 is a normally closed valve of the water supply port 18 provided at the bottom of the tank 17, and when the tank 17 is mounted, the normally closed valve 20 is moved upward by the push-up part 21 provided in the water conduit 16 to open the water supply port 18. Then the tank
The water in 17 is made to flow into the water conduit 16. A nozzle portion 22 is provided on the outlet side of the water conduit 16 and is connected to the vaporization chamber 14 via a seal packing 23. Thus, the tank 17
The water inside is supplied to the vaporization chamber 14 via the water conduit 16. A cylinder 24 of the pump device 25 is located between the inlet and the outlet of the water conduit 16, and is connected to the water conduit 16. 26 is the above cylinder
An electric device, such as an electromagnetic solenoid, arranged above the pump 24.
Is pulled up, and when the current is cut off, the pump device 25 is pushed down by the spring 27 that biases the pump device 25 downward. Reference numeral 28 denotes a ball which is arranged to freely move in the water conduit 16 so as to face the lower end of the pump device 25, and the vertical motion of the pump device 25 causes the ball 28 to move through the ball 28.
Can be opened and closed. Reference numeral 29 denotes a handle that surrounds the electric device 25 and the like and is mounted on the cover 15. A switch 30 for switching between "steam" and "dry" is provided on the front portion of the upper surface thereof.
And a switch 31 for driving the electric device 25 to generate “increasing steam”.

Next, the operation of the structure of this embodiment will be described.

The electric device 25 is off when the iron is not energized.
In this state, the pump device 25 is pushed downward by the spring 27 and the water conduit 16 is closed by the ball 28.
Then, when the tank 17 containing water is attached to the iron, water flows into the water conduit 16 from the water supply port 18, but since the water conduit 16 is closed by the ball 28, the water is not supplied to the vaporization chamber 14 It is the state of. After the base 11 is heated to a temperature at which water can be vaporized, when the switch 29 is operated, the electric device 26 is energized and the solenoid is excited, so that the pump device 25 overcomes the spring 27 and is pulled up, and the lower end of the pump device 25 is pulled up. Release the push down of ball 28 at. Therefore, the water in the tank 17 passes through the water conduit 16 and the nozzle part
It is restricted by 22 and supplied to the vaporization chamber 14, and normal steam can be ejected.

And when switching to "dry", the switch
When the electric power to the electric device 26 is cut off by the operation of 29 and the excitation of the solenoid is released, the pump device 25 descends due to the action of the spring 27, the ball 28 at the lower end thereof is pushed down and the water conduit 16 is closed, and the vaporization chamber 14 It can stop the flow of water into and be "dry".

Next, when a large amount of steam is temporarily needed during ironing, the switch 31 for "increase steam" is pressed to turn on the electric power to the electric device 26 by an electronic circuit (not shown) or the like. By energizing and de-energizing the solenoid automatically by turning it ON / OFF at intervals, a large amount of water is temporarily vaporized from the nozzle part 22 by repeating the reciprocating motion of the pump device 25 with a predetermined stroke. It can be forcibly supplied to the chamber 14 and "increasing steam" can be ejected. In this way, by simply pressing the switch 31 for "increasing steam", the "increasing steam" can be jetted any number of times or for any time. Then, when the "increasing steam" is stopped, it can be easily released by pressing the switch 31 again.

The interval for turning on / off the power to the electric device 26 can be freely selected according to the relationship with the vaporization capacity of the vaporization chamber, and the amount of water supplied once can be arbitrarily set. it can. Further, one switch for operation may be used.
What is essential is that the electric device controls the switching between "steam" and "dry" by opening and closing the water conduit and the increasing steam for temporarily supplying a large amount of water to the vaporization chamber.

Effects of the Invention As described above, according to the present invention, a switch for driving the electric device by opening and closing the water conduit and operating the increasing steam that temporarily supplies a large amount of water to the vaporization chamber by the electric device. It can be performed by a simple operation that only lightly presses.
