Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a steam iron having a removable water supply tank.

[Technical background of the invention and its problems] Recently, a water supply tank has been removably attached to the iron body, and the tank can be separated from the iron body when filling and draining water, making it easier to fill and drain water. Many things are used.

This type of steam iron is equipped with a dripping nozzle, dripping operation lever, and its operation means on the tank side, and the tank has a water channel that opens only when it is attached to the iron body, and a dripping nozzle and dripping operation are installed on the iron body side. There are two types: those equipped with a rod and its operating means. These two types of cassette tank type steam irons each have their own advantages and disadvantages, but the latter is generally considered to be easier to use.

The disadvantage of this latter method is that when the tank is removed from the iron body, the water remaining in the water passageway on the iron body side will scatter to the outside during storage or when used as an automatic iron.

[Purpose of the invention]

The present invention aims to solve the above-mentioned problems, and is designed to prevent the water remaining in the water passage on the iron main body side from scattering to the outside when the tank is removed from the iron main body. This is the purpose.

[Summary of the invention]

The steam iron of the present invention has an iron body that has the function of vaporizing and spouting supplied water.
In this steam iron, a tank for supplying water to the iron body is detachably provided, and the iron body has an open state when the tank is attached to the iron body at the inlet of a water passage communicating with the vaporization part. The tank is also provided with a valve device that is closed when the tank is removed from the iron body, and the tank is provided with a valve device that opens when the tank is attached to the iron body, at a water opening that communicates with the inlet of the water passage of the iron body. The device is characterized by being provided with a valve device which supplies water to the water passage when the iron is in the closed state and which is closed when the tank is removed from the iron body.

Next, the operation will be explained.

As shown in Figure 1, insert the tank 31 into the iron body 1.
When attached to the tank attachment part 11 of the tank 31, the joint 34 at the bottom of the tank 31 fits into the connection port 22 of the heat shield plate 9, and the pushing piece 36 pushes down the valve body 26 to open the valve hole 24, and the valve body 26 is pushed down and the valve hole 24 is opened. At the same time, the lower end of the valve rod 43 of the tank 31 contacts the upper end of the opening/closing rod 25 and is pushed up together with the valve body 44, opening the water inlet 35.
Water in the tank 31 is guided to the water passage 14 through the communication hole 46 of the valve frame 42, the water passage port 35, and the communication port 37. At this time, the cylindrical portion 23 of the packing 13 is connected to the joint 3.
4 and is held in a lowered state by a predetermined height. In this state, when the operating button 18 is set to the "steam" state and the operating rod 16 is pulled up, the water in the water passage 14 is dripped from the dripping nozzle 15 into the vaporization chamber 4 of the base 2, where it becomes steam. Steam passes through the steam passage 5 and is ejected from each steam ejection hole 6 onto the lower surface of the base 2.

Moreover, as shown in FIG. 2, when the tank 31 is removed from the iron body 1, the valve device 4 of the tank 31
1, the valve body 44 is lowered together with the valve rod 43 by the biasing force of the coil spring 45, and the valve body 44 closes the water inlet 35 to prevent water leakage from the tank 31.

At the same time, in the valve device 21 of the iron body 1, the cylindrical portion 23 of the gasket 13 returns to its compressed height and rises, and the valve body 26 is pushed up by the biasing force of the coil spring 28, causing the cylindrical portion of the gasket 13 to rise. The valve hole 24 of the portion 23 is closed, and a gap is formed in the restored and raised height portion of the cylindrical portion 23 to prevent water from entering, thereby preventing water in the water passage 14 from scattering to the outside.

Moreover, as shown in FIG. 3, the tank 31 is removed from the iron main body 1, and the drip nozzle 1 is
When the heater 3 of the base 2 is energized with the heater 3 closed, the water in the water passage 14 is heated and the pressure inside the water passage 14 is increased. When this pressure rises above a specified value, the water in the passageway 14 turns into steam, etc., and the water flows through the slit 27 against the elastic force of the valve body 26.
The water is spread out and ejected to the outside, and the pressure inside the passageway 14 is reduced.

In this way, when the tank 31 is removed from the iron body 1, the water inlet 35 of the tank 31
is closed by the valve device 41 to prevent water from leaking from the tank 31, and the water passage 14 of the iron body 1 is closed.
The inlet of the water passageway 14 is closed by the valve device 21, so that the water in the water passageway 14 does not scatter to the outside.

Furthermore, if the pressure inside the water passage 14 rises above a specified value with the tank 31 removed from the iron main body 1, the water within the water passage 14 will turn into steam or the like and be blown out to the outside, so it is safe. .

In the embodiment shown in FIGS. 1 to 3 above, the valve body 26 of the valve device 21 of the iron main body 1 is fitted with the opening/closing rod 25 and is provided to be movable up and down, but as shown in FIGS. As shown in the figure, the height of the opening/closing rod 25 is lowered so that the valve body 26 moves up and down above it, and when the tank 31 is installed, the valve body 26 is pushed down by the pushing piece 36 of the joint 34 of the tank 31. At the same time, the valve device 41 of the tank 31 may be opened by bringing the valve rod 43 of the tank 31 into contact with the opening/closing rod 25 via the valve body 26.

Furthermore, in the embodiments shown in FIGS. 1 to 3 above,
A slit 27 is formed in the valve body 26 of the valve device 21 as a safety mechanism of the iron body 1, but as shown in FIGS.
4 may be communicated with the vaporization chamber 4 of the base 2. That is, in this embodiment, the opening/closing rod 25
The height of the opening and closing rod 25 is lowered so that the valve body 26 can move up and down above it, and a water passage hole 61 that penetrates vertically is formed in the center of the opening/closing rod 25.
is communicated with the vaporization chamber 4 of the base 2 via the communication frame 62, and a ball-shaped safety valve 64 biased upward by a coil spring 63 is provided at the lower end of the water passage hole 61, so that the internal pressure of the water passage 14 is regulated. When the pressure is below the specified value, the water hole 61 is closed by the safety valve 64, and when the internal pressure of the water passage 14 rises above the specified value, the water in the water passage 14 pushes the safety valve 64 open against the force of the coil spring 63. The steam is pushed out from the water passage hole 61 of the opening/closing rod 25 into the vaporizing chamber 4, where it becomes steam and is jetted out from the steam jet hole 6 onto the lower surface of the base 2. By doing so, the steam is ejected onto the lower surface of the base 2, further improving safety.

In addition, in carrying out, the valve device 21 and safety mechanism of the iron body 1, the valve device 41 of the tank 31,
In addition to the above-mentioned embodiments, an appropriate one can be selected.

〔Effect of the invention〕

According to the present invention, when the tank is removed from the iron main body, the water inlet of the tank is closed by the valve device of the tank to prevent water from leaking from the tank, and the inlet of the water channel of the iron main body is closed by the valve device of the iron main body. The water in the passageway is closed and the water in the passageway does not splash outside, making it safe to use.
