It was difficult to operate when using "increase steam".

In other words, ironing work involves moving the iron,
In addition to the pressure action required to press clothing being carried out in a well-balanced manner by the hands of the worker, especially when using the "increasing steam" function, the operator must repeatedly move the operation button up and down at the same time, making it difficult for the worker's hands to press. There was a problem that it placed a burden on the hands and fingers, making it difficult to use.

Therefore, the present invention aims to generate steam by opening and closing the water conduit.
The purpose of the present invention is to provide an easy-to-use steam iron with improved operability when switching between "dry" mode and when using "increase steam" that temporarily supplies a large amount of water to the vaporization chamber.

Means for Solving the Problems And in order to achieve the above object, the present invention provides a conduit for supplying water in a tank to the vaporization chamber, a pump device connected to the conduit, and a pump device. A driving electric device is provided, and the electric device opens and closes the water conduit;
This is to control the increased amount of steam that temporarily supplies a large amount of water to the vaporization chamber.

Function The iron of the present invention has the above-mentioned configuration, so that the opening and closing of the water conduit and the operation of the pump device that temporarily supplies a large amount of water to the vaporizing chamber are extremely simple, just by lightly pressing a switch to drive the electric device. This can be done with simple operations. therefore,
Since the iron can be easily operated while moving and pressing the iron during ironing work, the usability can be greatly improved.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIG. 1, reference numeral 11 denotes a base heated by a heater 12, which forms a vaporization chamber 14 covered with a lid 13. Reference numeral 15 denotes a cover that covers the upper surface of the base 11, and a water conduit 16 is attached to the upper surface of the cover, in which a plurality of members are connected by heat or ultrasonic welding. The inlet of this water conduit 16 is open on the top surface, and is sealingly connected by a backing 19 to face a water supply port 18 that is open at the bottom of a detachable tank 17. Reference numeral 20 denotes a normally closed valve for the water supply port 18 provided at the bottom of the tank 17. When the tank 17 is attached, the normally closed valve 20 is moved upward by a push-up portion 21 provided in the water conduit 16, and the water supply port 18 is opened. The water in the tank 17 is caused to flow into the water conduit 16. Further, 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 backing 23. In this way, tank 1
Water in the vaporizer 7 is supplied to the vaporization chamber 14 via the water conduit 16. A cylinder 24 of a pump device 25 is located between the inlet and the outlet of the water conduit 16, and is connected to the water conduit 16. 2
Reference numeral 6 denotes an electric device consisting of an electromagnetic solenoid or the like placed above the cylinder 24, which is electrically controlled and pulls up the pump device 25 when current flows, and urges the pump device 25 downward when the current is cut off. The spring 27 pushes the pump device 25 downward.

On the second day, the water conduit 16 is located opposite the lower end of the pump device 25.
The pump device 25 is a ball freely disposed within the pump device 25.
The water conduit 16 can be opened and closed via the ball 28 by vertical movement of the ball 28 . Reference numeral 29 denotes a handle attached to the cover 15 to surround the electric device 25, etc., and a switch 3 for switching between "steam" and "dry" is provided at the front of the top surface of the handle.
0 and a switch 31 that drives the electric device 25 to generate "increased steam".

Next, the operation of the configuration of this embodiment will be explained.

When the iron is not energized, the electric device 25 is
In the FF state, the pump device 25 is pushed down by the spring 27 and the water conduit 16 is closed by the ball 28. When the tank 17 filled with 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, it is not supplied to the vaporization chamber 14, and the water is not supplied to the vaporizing chamber 14. ” condition.

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 energized, so that the pump device 25 is pulled up over the soup ring 27 and the ball 28 at the lower end of the pump device 25 is released from being depressed. Therefore, the water in the tank 17 passes through the water conduit 16, is restricted by the nozzle part 22, and is supplied to the vaporization chamber 14, so that normal steam can be ejected.

When switching to "dry", the power supply to the electric device 26 is cut off by operating the switch 29, and when the solenoid is de-energized, the pump device 25 is lowered by the action of the spring 27, and the ball at the lower end of the pump device 25 is lowered. 28
can be pushed down to close the water conduit 16 and stop the flow of water into the vaporization chamber 14 to make it "dry."

Next, if you temporarily need a large amount of steam while ironing, press the "increase steam" switch 31, and an electronic circuit (not shown) or the like will turn on electricity to the electric device 26 at a specified level. By turning 0N10FF at intervals, the solenoid is automatically energized and de-energized, so that the pump device 25 repeats reciprocating motion at a predetermined stroke to temporarily pump a large amount of water from the nozzle portion 22 to the vaporization chamber 14. It is possible to forcibly supply the steam to the tank and eject "increased steam". In this way, "increase steam"
By simply pressing the switch 31, "increased steam" can be ejected an arbitrary number of times or for an arbitrary period of time. and,
To stop this "increase steam", switch 3 above.
It can be easily canceled by pressing 1 again.

Note that the interval at which the electric device 26 is energized from ON to 10 F F can be freely selected depending on the relationship with the vaporization capacity of the vaporization chamber, and the amount of water supplied twice can also be set arbitrarily. can. Furthermore, the operation may be performed using only one switch. In short, any electric device may be used as long as it controls the switching between "steam" and "dry" by opening and closing the water conduit, and the increased amount of steam that temporarily supplies a large amount of water to the vaporization chamber.

Effects of the Invention As described above, the present invention uses an electric device to open and close the water conduit and to operate the increased steam that temporarily supplies a large amount of water to the vaporization chamber, thereby providing a switch for driving the electric device. This can be done by simply pressing lightly. Therefore, the iron can be easily operated while moving the iron and pressing against the clothes during the ironing operation, thereby significantly reducing the fatigue of the hands and fingertips and greatly improving the usability.
