Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a steam iron for general household use.

Conventional structure and its problems Conventional steam irons communicate with the vaporization chamber through a drip nozzle installed at the bottom of the tank, and this drip nozzle is manually opened and closed to supply and stop water. is common.

Therefore, if the temperature of the base surface is adjusted to be lower than the appropriate temperature that can generate steam due to operator misuse, or if the base surface is used without being sufficiently heated, the supply to the vaporization chamber may occur. The water was not completely vaporized, causing water leaks. In addition, if the drip nozzle is opened with water left in the tank after use, and the tank is left in a horizontal position, the water in the tank will flow into the vaporization chamber and the steam passage leading to the steam hole, corroding the base. There were some drawbacks as well.

In order to solve these drawbacks, a method of sensing the heat from the base and controlling the water supply to the vaporization chamber by opening and closing the dripping nozzle using a bimetal installed in the vaporization chamber has been considered. there was.

However, bimetals are constantly in contact with boiling water and steam in the vaporization chamber, and when repeatedly dried, they corrode and accumulate limescale, making them unreliable.

Furthermore, even though the bimetal senses the heat of the base and opens the dripping nozzle during use, the water that cannot be supplied from the dripping nozzle is cooled, so the dripping There was also a drawback that the nozzle was clogged and a stable steam jet could not be obtained.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, prevents problems caused by incorrect use and operation by workers, and provides an improved water control mechanism that can emit stable steam and can be used for a long period of time. It provides a steam iron that lasts a long time.

Structure of the Invention In order to achieve the above object, the present invention provides a base, a vaporization chamber provided on the base, a tank disposed above the base, and communication between the tank and the vaporization chamber, and an opening/closing mechanism. By providing a water passage with a device and this water passage integrated with the tank, it is possible to rationally control water from the tank to the vaporization chamber, and the opening/closing device is integrated into the tank side, making it possible to connect the tank to the vaporization chamber. This makes it easy to connect rooms.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a base in which a heater 2 is embedded, and a vaporizing chamber 3 and a steam hole 4 are formed therein. 5 is a base lid that covers the vaporization chamber 3, and 6 is a cover that covers the entire base 1 from above, and has four parts 6a formed approximately in the center. 7 is a handle installed above the base 1, and there is a tank 8 inside.
is formed. Reference numeral 9 denotes a bottom plate fixed to the lower surface of the handle 7 to define the tank 8. The bottom plate 9 has an opening 1o and a cylindrical projecting portion 11 projecting upward. is formed.

A water passage forming member 13 is fixed to the back surface of the bottom plate 9 facing the recess 6a of the cover 6, and covers the opening 10 and the lower surface of the protruding cylindrical part 11.
4 is formed. Reference numeral 15 denotes a recess formed in the base 1 at a position close to the vaporization chamber 3, and a thermally responsive member 16 such as a reversible bimetal that senses the base temperature and performs reversal operation is disposed within the recess 15.

17 is a lid that covers the recess 15, and in the center of this lid 17 is a pin 1 that moves up and down in response to the reversal action of the thermally responsive member 16.
A guide hole 19 for slidably holding the slider 8 is formed. Reference numeral 20 denotes a first opening/closing device having a valve shaft 20 & integrally provided with an opening/closing valve 21 for opening/closing the opening 10 at the upper part thereof, and a valve shaft 20& for opening/closing the opening 10. Penetrates through the opening 22 and by the spring 23,
The on-off valve 21 is biased downward to close the opening 10.

24 is a flexible backing that covers the lower surface of the opening 22 of the water passage forming member 13. The first switchgear 2o has pin 1
8 to open and close the opening 10 by vertically moving in response to the vertical movement caused by the reversing operation of the thermally responsive member 16. Reference numeral 25 denotes a drip nozzle provided in the water passage forming member 13 opposite to the lower surface of the protruding cylindrical portion 11. An opening 26 is formed in the base lid 6 located below the dripping nozzle 25, and water dripping from the dripping nozzle 25 is supplied into the vaporization chamber 3 through this opening 26. 27 is a second opening/closing device having an opening/closing rod 27a and the like that moves up and down inside the protruding cylindrical portion 11 and opens/closes the drip nozzle 25 at its lower end;
Although it is always biased upward to open the opening of the drip nozzle 25, when the operation button 28 at the upper end is manually pressed downward, the opening/closing frame 272L- lowers and closes the opening of the drip nozzle 26. 29 is a backing that connects the drip nozzle 26 and the opening 26 of the base lid 6.

In the above configuration, when ironing is performed using steam, the operation button 28 is released from the depression, the opening/closing frame 27& is raised, and the opening of the dripping nozzle 25 is opened. When the temperature of the base 1 is lower than the appropriate steam temperature, such as when the heater 2 is initially energized, the thermally responsive member 16 is in the state shown in FIG. 1, and the on-off valve 21 closes the opening 10. Therefore, water does not flow into the water passage 14 and is not supplied into the vaporization chamber 3 even if the drip nozzle 25 is opened.

Then, when the base 1 is heated by the heater 2 and reaches an appropriate temperature to vaporize the water, the thermally responsive member 16 is reversed as shown in FIG.
L is raised and the opening 10 is opened by the first opening/closing device 20. In this state, the water in the tank 8 flows through the water passage 1
The steam generated in the vaporizing chamber 3 is discharged from the steam hole 4.

Of course, even when in use, press down the operation button 28,
It is possible to stop the supply of water to the vaporization chamber 3 by closing the drip nozzle 25 with the second opening/closing device 27, and switching between steam and dry mode can be performed arbitrarily by manual operation.

In this way, the water passage 14 connecting the tank 8 and the vaporization chamber 3
is formed integrally with the tank 8 by the bottom plate 9 and the water passage forming member 13, so that the first opening/closing device 20 and the first opening/closing device 20 are connected to the tank 8 side of the drip nozzle 25, which is the opening of the water passage 14 on the vaporization chamber 3 side. The second opening/closing device 27 is constructed integrally with the tank, and the tank 8 as a whole is unitized. The Ushidamizu passage forming member 13 has a force of -6 recess 6&
Since the tank 8 and the cover 6 are provided opposite to each other, the heat insulating space between the tank 8 and the cover 6 can be effectively utilized.

Effects of the Invention As described above, the steam iron of the present invention has a water passage connecting the tank and the vaporization chamber integrated with the tank, and a unit of the opening/closing device for controlling this water passage to the tank. This makes it possible to easily connect the sole of the tank and the vaporizing chamber, and also improves the ease of assembling the iron.

It also has the effect of making effective use of the insulation space provided between the tank and the engine.
