Problems to be Solved by the Invention As described above, conventional steam irons have a mechanism that generates normal steam, a mechanism that generates a large amount of steam at once, and a mechanism that releases spray to the outside of the iron. 3 and opening/closing device 10. Since the pump device 6 and the nozzle 7 and the pump device 8 and the spray nozzle 9 are composed of independent parts, the structure is complicated and the assembly process is complicated. Moreover, there are many openings at the bottom of the tank 6, and there are also many connection parts with the vaporization chamber 4, which has disadvantages in terms of reliability against water leakage, etc. In addition, each mechanism has its own button 12, 13.1.
4, it is complicated to use.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a steam iron that has a simpler structure and is easier to operate.

Means for Solving the Problems In order to achieve this object, the steam iron of the present invention includes a pace heated by a heater, a vaporizing chamber provided on the base, and a tank provided above the vaporizing chamber. , a pump device for forcibly draining the water in the tank, and a communication waterway system communicating with the drainage side of the pump device, and a vaporization chamber side waterway leading to the vaporization chamber on the outflow side of the communication waterway;
This configuration includes a spray-side water channel leading to the spray nozzle, and a switching device for guiding water to one of the water channels.

Function According to the above structure, when the switching device selects the water channel on the vaporizing chamber and the spray nozzle side and the pump device is operated, the water in the tank flows into one of both water channels via the communicating channel, spraying water or spraying a large amount at once. can generate steam. Furthermore, if water is introduced into the communication waterway between the tank side and the vaporization chamber side, the water in the tank can be introduced into the vaporization chamber side without operating the pump.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIG.

In the figure, 16 is a base in which a heater 16 is embedded, and a vaporization chamber 19 is formed on this base 16. A nozzle 17 is provided in the upper part of this vaporization chamber 19,
It communicates with the vaporization chamber side waterway 18b of the communication waterway system 18 formed in the tank 29, and regulates the amount of water supplied into the vaporization chamber 19. A cylinder 20 constituting a pump device 31 is provided on the inlet side of the communication waterway system 18, and this cylinder 20 is equipped with a ball valve 21 that moves up and down below, and sucks water from the bottom inlet 18aJ:J) tank 29. ing. The outflow side of the communication waterway system 18 is a vaporization chamber side waterway 18b,
A spray side water channel 23 for guiding water to the spray nozzle 22 is provided 9 and has an outlet 18c. Reference numeral 24 denotes a switching device that moves up and down near the branch between the vaporization chamber side waterway 18b and the spray side waterway 23 of the communication waterway system 18 to switch between the two waterways. The switching device 24 maintains an interlocking relationship with a button 26 that constitutes a part of the locking device. 26 is a piston that constitutes a pump device, and a coil spring 2 serves as an opening/closing device that moves up and down inside the cylinder 20 and cuts off and on the supply of water.
7 is provided at the tip. The piston 26 maintains an interlocking relationship with a button 28 forming part of the locking device.

Further, the piston 26 can be freely operated by the button 28 until the piston 26 is locked by the locking device.

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

First, the switching device 24 is operated with the button 26 to allow water to flow into the vaporizing chamber side waterway 18b, and when the specified amount of water is poured into the tank 29, the button 28 is operated and the piston 2
e to draw water into the cylinder 20 from the inlet 18a through the ball valve 21. Furthermore, button 28
By operating this, water can be supplied from the vaporization chamber side waterway 18b of the communication waterway system 18 to the vaporization chamber 19 via the nozzle 17. At the same time, the air in the communication waterway system 18 is also discharged to form a communication waterway. After the communication waterway is formed, the inlet 18
Water continuously flows out from a toward the nozzle 17, and water is supplied to the vaporization chamber 19, but the communication waterway system 18
Since it has a nozzle 17, water is continuously supplied to the vaporization chamber 19 while being regulated to an appropriate amount of water supply. The supplied water is vaporized in the vaporization chamber 19 by the heat of the base 16 heated by the heater 16, and the base hole 3, which is connected to the vaporization chamber 19 provided in the base 15, is vaporized in the vaporization chamber 19.
0 to the outside of the base 15 to enable use as a steam iron with a normal amount of steam. Furthermore, when you want a large amount of steam to further improve the ironing effect, you can operate the button 28 and supply the water sucked up into the cylinder 20 from the communication waterway system 18 to the vaporization chamber 19 to generate normal steam. In the same manner as above, a large amount of steam is discharged outside the base 15, resulting in a normal amount of steam and a large amount of steam iron at once. Note that if the operation of the button 28 is stopped, the steam iron continues to generate the normal amount of steam.

Next, the switching device 24 is operated by the button 26 to switch the outlet 1
8c, the water in the tank 29 is introduced into the outlet 18c of the communication channel system 18 by the piston movement caused by the operation of the button 28. It is supplied to the spray nozzle 22 through the tank 29 and discharged in the form of a mist to the outside of the tank 29, making it possible to sufficiently spray the necessary areas. Moreover, by operating the switching device 24 to the vaporizing chamber side waterway 18b, the steam iron immediately returns to the state where the normal amount of steam is generated.

Furthermore, when the normal amount of steam is no longer required, by pressing the button 28 and activating the locking device, the coil spring 2
At step 7, the ball valve 21 is pressed against the valve seat of the inlet 18a to cut off the communication waterway, stop the water supply, and stop the generation of steam. It instantly returns to a steam iron that can generate normal steam.

Effects of the Invention As described above, the present invention is capable of providing multiple functions using one pump device, a communicating waterway system, and a switching device.The number of parts can be reduced compared to the conventional one, and the structure is also improved. Since it is very easy to make, it is possible to provide an inexpensive steam iron. Moreover, it is very convenient to use, as only the pump device and the switching device need to be operated.
