Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a steam iron that has multiple functions such as temporarily ejecting a large amount of steam, varying the amount of steam ejected, and spraying from a spray nozzle. It is.

Conventional Structure and Problems A typical steam iron has a structure in which water is supplied from a tank to a vaporizing chamber, and steam generated in the vaporizing chamber is ejected. A steam iron having such a basic configuration will be explained with reference to FIG.

In the same figure, base 1 for ironing
A vaporization chamber 3 is provided near a heater 2 embedded in the tank. A nozzle 4 for limiting the amount of water dripping is located above the vaporization chamber 3, and a tank 5 is provided above the nozzle 4. An operating rod 6 which penetrates this tank 5 and is movable up and down is arranged to open and close the opening of the nozzle 4 at the lower end thereof.

According to the above configuration, the nozzle 4 can be opened and closed by vertical movement of the operating rod 6, so that water in the tank 5 is vaporized in the vaporization chamber 3 through the nozzle 4, and steam is ejected or the ejection is stopped. You can However, since it only has the function of emitting steam and stopping the ejection of steam, it has not been possible to meet the demands of steam iron users, even though in recent years there has been a desire for multi-functional steam irons. For this purpose, as shown in FIG. 4, the lower end of the operating rod 6 that opens and closes the nozzle 4 is tapered, the lower end is inserted into the opening of the nozzle 4, and the opening is opened by moving the operating rod 6 up and down. A steam iron is constructed in which the amount of dripping into the vaporizing chamber 3 can be varied by changing the opening area, and a function that can vary the amount of steam ejected is added. However, in the above configuration, since the nozzle 4 is close to the vaporization chamber 3, the nozzle 4 is easily affected by heat, which may cause problems in dripping. In addition, a steam iron with a so-called shot function that temporarily ejects a large amount of steam is, as shown in FIG. 5, equipped with a pump device 7 in addition to the basic steam iron shown in FIG.
A nozzle 8 connected to this pump device 7 and facing the vaporization chamber 3 is additionally provided, and this pump device 7
By this operation, the water in the tank 5 is forcibly discharged into the vaporization chamber 3 through the nozzle 7, and a large amount of steam can be temporarily ejected. However, in order to add this shot function, it was necessary to newly provide a pump device 6 and a nozzle 7.

As mentioned above, in order to add functions to a basic steam iron, the number of parts increases, the cost increases, and the configuration becomes more complex, which lowers reliability and requires additional functions. The space these parts occupied inside the tank also increased, and there was a limit to the number of functions that could be added. In addition, because the nozzle of conventional general steam irons is located near the vaporization chamber, the iron is susceptible to the effects of heat, and steam cannot be ejected stably in some cases.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned problems, and provides a steam iron that requires few additional parts, has multiple functions, and can emit stable steam.

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; a spray nozzle disposed in front of the tank; and a spray nozzle formed in the tank. and a first communicating waterway that guides water in the tank to the vaporization chamber, and a second communicating waterway that branches from the first communicating waterway and leads to a spray nozzle disposed in front of the tank. , a pump device provided on the inflow side of the first communicating waterway, and an inlet provided in the first communicating waterway a certain distance above the bottom of the tank and opened at the bottom of the tank. The inflow port communicates with a flow rate adjustment device that stops the water supply of water flowing into the first communication channel to the vaporization chamber, varies the amount of water supplied, and sets the maximum amount of water supplied to the vaporization chamber to be greater than the vaporization capacity of the vaporization chamber. It is equipped with a switching device that selectively switches water flowing into the waterway to the first communication waterway and the second communication waterway.

According to the above configuration, it is possible to spray from the spray nozzle using the switching device, the amount of steam ejected can be adjusted using the flow rate adjustment device, and a large amount of steam can be temporarily ejected by operating the pump. This allows the steam iron to have multiple functions.

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

In Figure 1, 1 is the base, 2 is the heater, and 3
5 is a vaporizing chamber, and 5 is a tank, which are constructed in the same manner as the steam iron described above, and their explanation will be omitted.

Reference numeral 9 denotes a steam hole, which is provided on the surface of the base 1 and communicates with the vaporization chamber 3. Reference numeral 10 denotes a communicating waterway pipe, which has an H shape, that is, consists of an inflow side vertical section 10a, a horizontal section 10b, and an outflow side vertical section 10c, and is arranged at the lower part of the tank 5. The lower end of the outflow side vertical section 10c of this communication waterway pipe 10 is connected to the vaporization chamber 3, and the upper end of the inflow side vertical section 10a is connected to the lower end of the cylinder 12 of the pump 11 vertically arranged in the upper part of the tank 5. has been done. An inlet 13 is formed at the lower end of the inflow side vertical portion 10a of the communication waterway pipe 10, that is, a portion facing the inner bottom of the tank 5, and within the inflow side vertical portion 10a,
A vertically movable ball valve 14 is provided, and this communication waterway pipe 10 constitutes a first communication waterway that guides water in the tank 5 to the vaporization chamber 3. The pump 11 includes an actuating rod 15 that moves up and down within a cylinder 12, and a piston 16 provided at the lower end of the actuating rod 15. The actuating rod 15 can be maintained in the pushed state by a lock mechanism provided at its upper end. It's summery. A sliding adjustment rod 17 is inserted into the vertical portion 10c on the outflow side of the communication water pipe 10, and the upper end of the adjustment rod 17 has a metal fitting 1 whose pushing distance varies depending on the rotational position of the adjustment dial 18.
9 is installed. The lower end of the adjustment rod 17 is hollow, and a long hole 20 is formed in the side that intersects with the horizontal portion 10b of the communication waterway pipe 10, and has a tapered shape that becomes larger as it goes downward. ing. Reference numeral 21 denotes a gasket attached above the lower end of the adjustment rod 17, which slides on the inner wall of the outflow side vertical portion 10c of the communicating waterway pipe 10. Further, a chamber 22 provided on a side surface near the center of the outflow side vertical section 10c communicates with the outflow side vertical section 10c through a small hole. A spray nozzle 23 projecting toward the tip of the iron is attached to the upper part of this chamber 22.

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 10.
The steam flows into the inlet vertical part 10a and the horizontal part 10b, flows out through the elongated hole 20 at the tip of the adjustment rod 17 to the outflow vertical part 10c, is dripped into the vaporization chamber 3, and blows out steam from the steam hole 9. do. 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 and the outflow side vertical part 10c of the communicating water pipe 10 will be lowered.
Since the hole communicating with the vaporizer 3 becomes smaller and the amount of water supplied to the vaporization chamber 3 decreases, the amount of steam generated decreases. Further push down the adjustment rod 17 and
If the outflow port of the horizontal portion 10b of 0 and the gasket 21 overlap, the outflow of water to the vaporization chamber is stopped and steam is no longer ejected. If the gasket 21 is further moved below the inlet of the horizontal part 10b of the communication water pipe 10, the water flows through the horizontal part 10b and above the outflow side vertical part 10b by operating the pump 11, and the water flows through the chamber 22. It is ejected from the spray nozzle 23 in the form of mist. Moreover, if the adjustment rod 17 is pushed upward and the maximum opening of the elongated hole 20 overlaps the outlet of the horizontal part 10b of the communicating water pipe 10, a large amount of water will flow into the vaporization chamber 3.
Since the vaporization capacity of the hot water is exceeded, hot water flows out from the steam hole 9 and the steam hole 9 can be cleaned.

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 a small amount of water is supplied. Even in such cases, the passages are not blocked by bubbles generated by heat, and water can be stably supplied. Furthermore, 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, thereby preventing the steam hole 9 from clogging. Spraying can also be performed by switching to the spray nozzle 23 side. Furthermore, the gasket 21 provided on the adjustment rod 17 can close the outlet of the horizontal portion 10b of the communicating waterway pipe 10, so the water supply can be stopped and the iron can be operated dry, making the steam iron multi-functional. It can be done.
