And an iron body 1 connected to the on-off valve 4.
It is opened and closed by the operation of the operation unit 6 provided on the handle 5 of the iron main body 1, which will be described in detail later.

As shown in FIG. 2, the iron body 1 includes a heater 10 and a vaporizing chamber 11 for vaporizing water dropped by the heat of the heater 10 to produce steam. Communicates with an upper opening-shaped water supply port 12 that supplies water to the vaporization chamber 11, and through a plurality of lower opening steam outlets 13 provided at a front portion of the bottom surface 14 via a steam flow path 45. Communicating.

A female screw portion 12a which is screwed into a male screw portion 27 (described later) of the on-off valve 4 is provided on the inner peripheral surface of the water supply port 12. The heater 10 is controlled by a thermistor (temperature controller) (not shown) and is maintained at a predetermined temperature.

As shown in FIG. 2 and FIG.
Has a valve body 15 and a valve seat 16, and the valve body 15 is elastically urged toward the lower valve seat 16 by an elastic member 17 (such as a coil spring).

More specifically, the valve body 15 includes a shaft portion 15
a and a head portion 15b having an outer diameter larger than the shaft portion 15a, and is inserted into a first cylindrical body 18 having male screw portions 20a and 20b at upper and lower portions.

The first cylindrical body 18 has a polygonal (for example, hexagonal) bolt portion 21 on the outer peripheral surface at an intermediate portion thereof, and the shaft portion 15a of the valve body 15 projects upward from the bolt portion 21. An upper cylindrical portion 22 having an inner diameter substantially equal to the outer diameter is provided, and a lower cylindrical portion 23 having an inner diameter substantially equal to the outer diameter of the head portion 15b of the valve body 15 is provided so as to project downward from the bolt portion 21.

Then, a sealing member 24, a washer member 25 and a resilient member 17 are inserted into the lower cylindrical portion 23 of the first cylindrical body 18, and further,
The valve body 15 is inserted from the shaft portion 15a side. The male screw portions 20a, 20b are provided on the outer peripheral surfaces of the upper and lower cylindrical portions 22, 23, and the male screw portions 20a of the upper cylindrical portion 22 (described later) are provided.
The nut member 34 and the adjusting screw portion 41 (having a cap nut shape) are screwed together.

The second cylindrical body 19 is provided with a female screw portion 26 which is screwed into the male screw portion 20b of the lower cylindrical portion 23 of the first cylindrical body 18 on the upper inner peripheral surface thereof, and is provided between the intermediate portion and the lower portion. On the outer peripheral surface, there is provided a male screw portion 27 which is screwed with the female screw portion 12a of the water supply port 12 of the iron body 1 (described above).

The second cylindrical body 19 has a through hole 30 between the female screw portion 26 and the male screw portion 27 and an annular notch 31 along the outer peripheral edge of the through hole 30. A curved pipe member 32 is fixed to the notch 31. The pipe member 32 has a tip 33 inserted into the other end 9 of the water flow hose 2 to connect the on-off valve 4 to the water flow hose 2.

Further, below the through hole 30 of the second cylindrical body 19,
An annular protruding wall portion 28 protruding toward the axis is provided, and the periphery of the hole of the protruding wall portion 28 is the valve seat portion 16. That is, when the first cylinder 18 into which the valve body 15 is inserted and held is screwed to the second cylinder 19, the projection 29 at the tip of the head 15b of the valve body 15 fits into the hole. Then, the valve body 15 is elastically urged toward the valve seat 16 by the elastic member 17, and the on-off valve 4 is closed in a free state.

Thus, the proximal end 36 of the valve body 15 of the on-off valve 4
Is fixedly connected to one end 37a of a flexible wire 39 (for example, a wire) externally fitted to the flexible tube 38, and the valve body 15 is separated from the valve seat 16 by pulling the flexible wire 39. (Opening / closing valve 4 is opened)
Details will be described later.

One end 40a of the flexible tube 38 is inserted and fixed to the upper cylindrical portion 41a of the adjusting screw portion 41 (described above) which is screwed to the male screw portion 20a of the upper cylindrical portion 22 of the first cylindrical body 18. I have. Also,
The adjusting screw portion 41 is stopped by a nut member 34 at a lower portion thereof.

As shown in FIG. 4A, an operating portion 6 for opening and closing the on-off valve 4 (having a substantially a shape in a side view) can be pivoted back and forth on the tip of the handle portion 5 of the iron body 1. Is pivoted to. The other end 37b of the flexible wire 39 connected to the valve body 15 is fixedly connected to the hooking projection 42 of the operation unit 6.

At this time, the portion from the other end 37b to the middle of the flexible wire 39 fitted and covered on the flexible tube 38 passes through the inside of the handle 5 so as not to hinder the work. In addition, the holding portion 43 of the operation unit 6 is inclined rearward in the free state.

As shown in FIG. 4 (b), when the pressing portion 43 of the operating portion 6 is pressed to swing forward, the other end 37b of the flexible wire 39 is pulled forward. Then, the valve body 15 of the on-off valve 4 connected to one end 37a of the flexible wire 39 is
It is pulled upward and separates from the valve seat 16. Then, water from the water passage hose 2 drops into the vaporization chamber 11 of the iron body 1 through the pipe member 32 and the second cylindrical body 19.

At this time, as shown in FIGS. 4 (b) and 5, the valve body 15 is pulled upward.
36a comes into contact with the inner surface 44 of the upper adjustment screw portion 41 and is stopped. That is, the degree of separation between the valve body 15 and the valve seat 16 is thereby adjusted.

Accordingly, as shown in FIGS. 2 and 3, the adjusting screw 41 screwed into the first cylindrical body 18 of the on-off valve 4 is screwed forward to adjust the adjusting screw 41 from the base end portion 36a of the valve body 15. The distance dimension W to the inner surface 44 of the portion 41 is reduced, and the degree of separation can be reduced. That is, the water from the water supply hose 2 can be dropped (water-supplied) little by little into the vaporization chamber 11.

On the contrary, if the adjusting screw portion 41 is screwed back, the above-mentioned interval dimension W becomes large and the degree of separation between the valve body 15 and the valve seat portion 16 becomes large, so that a relatively large amount of water is vaporized at one time. It can be dropped (water supply) into the chamber 11. Then, the water in the vaporization chamber 11 of the iron main body 1 is turned into steam by the heat of the heater 10 heated to a predetermined temperature, and is spouted from the steam outlets 13 on the bottom surface 14 through the steam flow path 45.

The present invention is not limited to the above-described embodiment. For example, the flexible wire 39 may be slid forward and backward to pull the flexible wire 39 in addition to the longitudinal swing type operation unit 6 described with reference to FIG. Alternatively, the flexible wire 39 may be wound and pulled in a rotary manner.

[0027]

Since the present invention is configured as described above, the following effects can be obtained.

The opening / closing valve 4 provided at the water supply port 12 of the iron body 1 is relatively lightweight, so that the entire iron is lightened and the iron is easy to handle. (Especially all-day ironing work) can be reduced. In addition, since the on-off valve 4 is compact, it does not become an obstacle, and fine ironing can be easily performed.

The dropping iron according to the present invention does not use an electromagnetic valve as a source of electromagnetic waves, but rather opens and closes the on-off valve 4 by operating the operation unit 6. Electromagnetic waves that could cause the thermistor (temperature controller) that controls 10 to malfunction will not be generated. That is,
The heater 10 may be overheated due to the malfunction of the thermistor, or conversely, the temperature of the heater 10 may not be increased and the steam may not be produced.However, the present invention prevents the malfunction of the thermistor and improves the efficiency. Ironing work can be done.

By providing the operating portion 6 at the tip of the handle portion 5 having an iron (according to claim 2), the operation can be easily performed by pressing the operating portion 6 with a finger.

According to the third aspect of the present invention, the degree of separation between the valve body 15 and the valve seat 16 (ie, the degree of opening of the on-off valve 4) can be finely controlled by screwing the adjusting screw 41 forward and backward. The amount of water (the amount of water supply) dropped from the water passage hose 2 to the vaporization chamber 11 in the iron body 1 can be finely adjusted.
That is, since the amount of steam to be spouted can be adjusted, for example, in the case of ironing with a large area, the amount of steam can be increased, and in the case of fine ironing, the work can be performed with a reduced amount of steam.

(According to claim 4) The other end 37 of the flexible wire 39
By passing through the handle part 5 from b to the middle, it is refreshing, and it does not catch on hands or things,
Does not interfere with work.
