The opening area of the valve hole of the drip portion is increased or decreased by an opening / closing rod interlocked with the movement of the lock button to adjust the amount of water dropped into the vaporization chamber.

The steam iron of the present invention can be operated by one push button for switching between steam and dry and adjusting the amount of steam with the above configuration, and any of the above operations can be performed by pressing the push button. It becomes like that.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 to 5, reference numeral 1 denotes a base heated by a heater 2, which forms a vaporization chamber 3 and communicates with a steam chamber 5 having a plurality of steam ejection holes 4. 6
Is a vaporization chamber cover installed on the base 1, and provided with a drip portion 7 facing the vaporization chamber 3. Numeral 8 denotes a tank provided above the vaporizing chamber 3, which is constituted by a handle 9 and a base cover 10 and is sealingly connected to the vaporizing chamber lid 6 via the dripping part 7. An opening 7a for communicating the tank 8 with the vaporizing chamber 3 is provided at the bottom. An opening / closing rod 11 has a lower end facing the drip portion 7 and is rotatably arranged in the tank 8, and has an upper end projecting upward from the tank 8. Further, a groove 11b is provided facing the opening 7a of the drip portion 7 upward from the lower end. Further, a lock button 13 is provided on the upper end 11a of the opening / closing rod 11.
And are linked so as to interlock with the turning operation of the lock button 13. Reference numeral 14 denotes a handle cover having a button hole 15 formed at a position opposed to the upper end of the opening / closing rod 11, and the button hole 15 is fitted with a steam button 17 having a plurality of sharply angled nails 16 formed at equal intervals on a lower outer peripheral surface. It is inserted. 18 is the button hole 15
An annular guide formed on the handle cover 14 to surround the
18a are formed at equal intervals, and the locking portion 18a has an inclined surface inclined in one direction. 19 is the steam button 17
On the lock button 13 provided by fitting inside, a plurality of arms formed at equal intervals, the arm 19 is provided with an inclined surface inclined in the same direction as the locking portion 18a of the guide body 18, When the steam button 17 is pressed by the contact between the claw 16 of the steam button 17 and the arm 19, the lock button 13 is
The guide 18 rotates in one direction while descending, and sequentially moves the locking portions 18a of the guide body 18. Therefore, the vertical movement of the lock button 13 is absorbed by the spring 21, while the rotation is transmitted to the opening / closing rod 11 and rotates in conjunction with the lock button 13.

Next, the operation of the configuration of the embodiment will be described.
The supply and stop of water from the tank 8 to the vaporization chamber 3 and the adjustment of the amount of dripping of water are performed by the pressing operation of the steam button 17, and the rotation of the opening / closing rod 11 causes the opening provided on the lower surface of the dripping unit 7 to rotate. The opening area of 7a can be increased or decreased,
By closing the opening 7a, the supply of water to the vaporizing chamber 3 is stopped, and by fully opening the opening 7a, the amount of dripping into the vaporizing chamber 3 can be maximized, and strong steam can be ejected.

As shown in FIG. 4, in the case of “strong steam”, the opening 7a is located at a position where the groove 11b faces the opening 7a.
Is fully open. Therefore, a large amount of water in the tank 8 is supplied into the vaporization chamber 3 through the opening 7a, and a large amount of steam is generated.

Next, when switching from this state to “normal steam”, when the steam button 17 is pressed down in the direction of arrow A, the lock button
13 also descends with the steam button 17 against the spring 21. At this time, the claw 16 of the steam button 17 presses the inclined surface of the arm 19, and the contact position is changed to the locking portion 18a of the guide body 18.
, The lock button 13 is rotated in the direction of arrow B. Then, when the pressing force of the steam button 17 is removed in this state, the steam button is
With the rise of 17, the lock button 13 rises while rotating in the direction of arrow C along the inclined surface of the locking portion 18a. Therefore, the open / close rod 11 having the upper end 11a fitted to the lock button 13
Also rotates in conjunction with this.

At this time, the opening area of the opening 7a is reduced by the rotation of the opening / closing rod 11, and the groove 11b is shifted from the opening 7a. That is, the water in the tank 8 is adjusted at the opening 7a and supplied to the vaporization chamber 3, so that "normal steam" can be generated.

Further, when the steam button 17 is depressed, the lock button 13 rotates in the direction of arrow B in the same manner as the above-described operation, and the opening area of the opening 7a at this time is reduced by the rotation of the lock button 13.
11b is completely removed from opening 7a, and opening 7a is completely closed. Therefore, the water in the tank 8 is not
It is not supplied inside and becomes "dry".

In the above embodiment, the adjustment of “steam” is switched in two stages, but may be switched in multiple stages. In short, it is only necessary that switching between “steam” and “dry” and adjustment of the amount of steam can be performed by pressing the steam button.

Next, another embodiment of the present invention will be described. 6 to 8, the lock button 13 that rotates by pressing the steam button 17 is moved up and down in multiple steps, so that the opening and closing rod 11 linked with the lock button 13 is moved up and down in multiple steps. The water supply to the vaporization chamber 3 is switched between supply and stop, and the amount of water dripping is adjusted. For example, a conical valve 22 is integrally formed below the opening / closing rod 11, and the drip portion 7 is formed. Has a relatively large valve hole 23. The opening area of the valve hole 23 of the drip portion 7 is increased or decreased by the vertical movement of the opening / closing rod 11.

As shown in FIG. 7, in the case of “strong steam”, the opening / closing rod 11 is located at the uppermost position, and the opening area formed between the valve hole 23 and the conical valve 22 of the drip portion 7 is the largest, A large amount of water in the tank 8 is supplied into the vaporization chamber 3 through the opening 23, and a large amount of steam is generated.

Next, when switching from this state to "normal steam", when the steam button 17 is depressed in the direction of arrow A in FIG. 8, the lock button 13 also descends together with the steam button 17 against the spring 21. At this time, the nail of the steam button 17
16 presses the inclined surface of arm 19 and the contact position is the guide
The lock button 13 is rotated in the direction of the arrow B because the lock button 13 is displaced a little after the locking portion 18a of the lock 18 has passed. In this state, when the pressing force of the steam button 17 is removed, the steam button 17 is raised by the urging force of the spring 21 and the lock button 13 is
It rises while rotating in the direction of arrow C along the inclined surface a. Therefore, the opening / closing rod 11 in which the upper end 11a is fitted to the lock button 13 also rises while rotating in conjunction with this,
It is locked by the locking portion 24b that regulates at a position lower than the locking portion 24a, and the opening 23 is narrowed.
Can be generated.

Further, when the steam button 17 is pressed, the lock button 13 operates in the same manner as described above, and the lock portion 13 is located at a lower position.
Locked by 24c, the opening 23 is completely closed, the supply of water to the vaporization chamber 3 is stopped, and the state becomes "dry".

As described above, an arbitrary state can be easily selected by repeatedly performing the pressing operation of the steam button 17.

Effect of the Invention As described above, the present invention allows the steam button and the opening / closing rod to cooperate via the lock button, and by pressing the steam button, rotates the lock button to move the drop button to the vaporization chamber. By adjusting the amount of water dripping, switching between "steam" and "dry" and adjusting the amount of steam can be easily operated with one button, and the operation can be performed by the same one-way pressing operation Therefore, an efficient and easy-to-use iron steam iron is available, such as one-handed operation while ironing without interrupting work every time such an operation is frequently performed during ironing. can get.
