The operation of the steam iron configured as above will be explained below.

Water in the tank 6 flows into the nozzle 4, drips into the vaporization chamber 3 through the gap created between the drip port 8 and the lower tip 7 of the adjustment rod 5, and is vaporized. Next, when the adjustment rod 5 is pushed down, the gap between the drip opening 8 of the nozzle 4 and the lower tip 7 of the adjustment rod 5 narrows, and the amount of drip from the nozzle 4 decreases. If the adjustment rod 5 is further pushed down, the drip opening 8 of the nozzle 4 is completely closed and the supply of water to the vaporization chamber 3 is stopped.

However, in the above configuration, since the nozzle 4 is located at the upper part of the vaporization chamber 3, bubbles are generated in the water in the nozzle 4 due to the heat of the vaporization chamber 3, and these bubbles block the drip port 8. Water vaporizes in chamber 3
There was a problem that the supply was no longer available.
In addition, water scale etc. tend to accumulate in the steam hole 9,
This had the problem of making the steam flow worse.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned problems and provides a steam iron that can prevent unstable water dripping due to the influence of heat and can remove water scale from the nozzle portion, etc.

Configuration of the Invention In order to achieve the above object, the steam iron of the present invention includes a base heated by a heater;
a vaporization chamber formed in the base; a tank disposed above the base for storing water to be supplied to the vaporization chamber; and a tank formed in the tank to allow water in the tank to be The amount of water supplied to the vaporization chamber through the communication waterway leading to the chamber and the water flowing into the communication waterway from an inlet that is provided in the communication waterway a certain distance above the bottom of the tank and opened at the bottom of the tank. It is equipped with a flow rate adjustment device that changes the flow rate.

According to the above configuration, since the vaporization chamber and the flow rate adjustment device are provided separately from the vaporization chamber, they are not easily affected by heat. Further, the amount of water fed into the vaporization chamber can be freely adjusted using the flow rate adjustment device, and water exceeding the vaporization capacity can be dripped into the vaporization chamber.

DESCRIPTION OF EMBODIMENTS A steam iron according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In Figure 1, 1 is a base, 2 is a heater,
3 is a vaporization chamber, 6 is a tank, and 9 is a steam hole, which are constructed in the same manner as the steam iron described above, and their explanation will be omitted.

Reference numeral 10 denotes a communicating waterway pipe, which has an H shape, that is, an inflow side vertical part 10a, a horizontal part 10b, and an outflow side vertical part 1.
0c, and is arranged at the lower part of the tank 6. The lower end of the outflow side vertical portion 10c of this communication waterway pipe 10 is connected to the vaporization chamber 3, and the inflow side vertical portion 10a
The upper end is connected to the lower end of a cylinder 12 of a pump 11 vertically disposed in the upper part of the tank 6. And the inflow side vertical portion 10a of the communication waterway pipe 10
An inflow port 13 is formed at the lower end of the tank 6, that is, a portion facing the inner bottom of the tank 6, and a ball valve 1 that is vertically movable is formed within the inflow side vertical portion 10a.
There are 4. The pump 11 is a cylinder 1
The actuating rod 15 is provided with an actuating rod 15 that moves up and down within the actuating rod 15, and a piston 16 provided at the lower end of the actuating rod 15, and the actuating rod 15 can be maintained in a pushed-in state by a lock mechanism provided at its upper end. An adjustment rod 17 is inserted into the vertical portion 10c on the outflow side of the communication waterway pipe 10, and a metal fitting 19 is attached to the upper end of the adjustment rod 17 so that the distance it can be pressed down varies depending on the rotational position of the adjustment dial 18. There is. In addition, the lower end of the adjustment rod 17 is hollow, and the connecting water pipe 1
A long hole 20 is formed in a side surface intersecting with the horizontal portion 10b of 0. The elongated hole 20 has a tapered shape that becomes larger as it goes upward.

The operation of the steam iron configured as above will be explained below.

The ball valve 14 is pushed up by the water pressure in the tank 6, and the water flows from the inlet 13 to the communication water pipe 1.
0 flows into the inflow side vertical part 10a and horizontal part 10b, flows out through the elongated hole 20 at the tip of the adjustment rod 17 to the outflow side vertical part 10c, is dripped into the vaporization chamber 3, and is steamed from the steam hole 9. gush out. If the adjustment dial 18 is rotated and the adjustment rod 17 is pushed down, the position of the tapered elongated hole 20 will also be lowered, and the horizontal part 10b of the communicating water pipe 10 and the outflow side vertical part 10 will be lowered.
Since the hole communicating with c becomes larger and the amount of water supplied to the vaporization chamber 3 increases, the amount of steam generated increases. If the adjustment rod 17 is further pushed down and the maximum opening of the elongated hole 20 overlaps the outlet of the horizontal portion 10b of the communicating water pipe 10, a large amount of water will flow into the vaporization chamber 3, exceeding the vaporization capacity of the vaporization chamber 3. Therefore, it flows out from the steam hole 9 in a liquid state, and the steam hole 9 can be cleaned. Furthermore, when the adjustment rod 17 is pushed upward, the position of the elongated hole 20 that communicates the horizontal part 10b and the outflow side vertical part 10c of the communication waterway pipe 10 also moves upward from the outlet of the horizontal part. The water supply is stopped and no steam is ejected.

According to the above configuration, since the part that adjusts the flow rate of the communication waterway pipe 10 is provided in the tank 6 at the upper part of the vaporization chamber 3, it is less affected by the heat of the vaporization chamber 3 and supplies a small amount of water. Even in such cases, the passages are not blocked by bubbles generated by heat, and water can be stably supplied. Moreover, if the amount of water supplied to the vaporization chamber 3 is maximized, the water flows out from the steam hole 9 in a liquid state, so that clogging of the steam hole 9 can be prevented.
Furthermore, since the water supply can be stopped, dry ironing is also possible, making it possible to provide a multifunctional iron at a low cost.

Effects of the Invention As described above, the steam iron of the present invention includes a base heated by a heater, a vaporizing chamber formed on the base, and a vaporizing chamber disposed above the base and supplied to the vaporizing chamber. a tank for storing water; a communicating waterway formed in the tank and guiding the water in the tank to the vaporization chamber; and a communicating waterway provided at a certain distance above the bottom of the tank, and Preventing the flow rate adjustment device from overheating due to heat from the base by including a flow rate adjustment device that varies the amount of water supplied to the vaporization chamber from water flowing into the communication waterway from the inlet opened at the bottom of the tank. This makes it possible to smoothly supply water to the vaporization chamber even when the flow rate is restricted, and to precisely adjust the amount of water supplied to the vaporization chamber.
