Description

[Detailed explanation of the device] This device drips water in a tank through a dripping valve into a steam generation chamber installed in a part of the base to instantly generate steam, which is then ejected from the steam hole in the base. Regarding the steam iron.

This type of iron obtains steam by dripping water into the steam generation chamber, so it has not been possible to prevent scale from accumulating when water is turned into steam directly under the dripping valve of the steam generation chamber.

However, if water scale deposits move due to external shocks, they block the steam vents and make it impossible to eject steam, which is a factor that impairs long-term stable use. .

Although it is possible to remove accumulated water scale using chemicals or the like, this method has the disadvantage that the parts in contact with the liquid are eroded by the chemical, impairing durability, and is not a practical measure.

Furthermore, in conventional irons of this type, the dripping valve is opened and closed by operating the on/off button provided on the handle, but if you forget to use this button to open the valve and store the iron, the remaining water in the tank will flow out and cause the iron to dry. Not only does it cause corrosion of the metal parts, but it also has the disadvantage of getting the storage box etc. wet.

Moreover, if the on/off button is opened before the base reaches a sufficient temperature during use, steam will not be generated but will leak out and wet the fabric.

This invention was devised for the purpose of providing a drip-type steam iron that can eliminate the various drawbacks of the prior art, and one embodiment of this invention will be described below with reference to the drawings.

In the figure, 1 is a base in which, for example, a heating element 2 is embedded, 3 is a base cover that covers the top surface of the base 1, and 4 is a handle attached to the top surface of the base cover 3.

The base 1 and the base cover 3 form an iron body,
A thermostat (not shown) for controlling the heat generation of the tank 5 and the heating element 20 is provided inside the main body.

Note that 6 is a dial for setting the operating temperature of the thermostat, and 7 is a power cord.

A steam generation chamber 9 is formed in the base 1 by a groove formed on the upper surface thereof and a lid 8 screwed onto the upper surface of the base 1 so as to close the opening of the upper surface of the groove. 9 and a required number of steam holes 10 opening on the lower surface of the base 1.

Inside the steam generation chamber 9, there is a water receiving plate 1 made of bimetal or the like.
It stores 1.

The water receiving plate 11 is, for example, in the shape of a dish that forms part of a spherical surface, and is always concave when the temperature of the base 1 reaches a temperature suitable for generating steam (for example, in this state, the water receiving plate 11 11 is about 160° C.), it elastically inverts and becomes convex, and when the temperature drops below the appropriate temperature, it elastically inverts and becomes concave.

The tank 5 is connected to a water inlet body 12 that opens on the front surface of the handle 4, and is also provided with a drip valve 13 facing substantially the center of the water receiving plate 11.

The drip valve 13 is interposed between the tank 5 and the lid 8, and the drip valve 13 is interposed between the tank 5 and the lid 8.
The Q valve seat body 14 communicates with the steam generation chamber 9, and the valve body 15 contacts and separates from the valve seat portion of the Q valve seat body 14.

The valve body 15 is connected to the approximate center of the water receiving plate 11 via a connecting rod 16, and with this structure, the valve body 15 is moved up and down in conjunction with the reversing operation of the water receiving plate 11, and the dripping valve 13 It is possible to open and close automatically.

Further, the valve body 15 is attached to the lower end of the valve stem 17, and the upper end of the valve stem 17 slidably passes through the vertical cylindrical portion of the water inlet body 12, and is constantly urged downward by a spring 18. be.

Note that 19 indicates a spring receiver fixed to the valve stem 17, and 20 indicates a relief portion when the valve stem 17 rises.

However, in this drip-type steam iron, in an emergency or for a while after the power is turned on, the water receiving plate 11 is
As shown by the dotted chain line, it has a concave shape, and the drip valve 13 is closed.

Therefore, the water in the tank 5 will not leak out from the dripping valve 13 through the steam generation chamber 9 and the steam hole 10.
There is no need for metal corrosion or wetting of storage boxes, fabrics, etc. as with conventional methods.

When the temperature of the base 1 rises and reaches a temperature sufficient to generate steam toward the steam generation chamber 8, the water receiving plate 11 is elastically reversed as shown by the solid line in FIG. It becomes convex.

Then, the valve body 15 is pushed up in conjunction with the water receiving plate 11 to open the dripping valve 13, so that the water in the tank 5 drips from the dripping valve 13 toward the water receiving plate 11.

Therefore, steam is generated instantaneously and this is caused by steam vent 1.
0, and the user irons the iron.

In this case, since the sound of the water receiving plate 11 reversing is generated, it is possible to easily know when ironing is possible by listening to the sound.

Since the falling water droplets are received by the water receiving plate 11 and evaporated there, water scale adheres to the upper surface of the water receiving plate 11.

Then, when the ironing operation is completed, the power is turned off, and when the temperature of the base 1 decreases, the water receiving plate 11 is elastically inverted so as to have a concave shape.

The water scale adhering to the upper surface of the water receiving plate 11 due to the shock at this time is broken into small pieces and peeled off from the water receiving plate 11.

Therefore, after this, the valve stem 17 is
By lifting up the dripping valve 13 and letting the water in the tank 5 drip, water scale is removed from the steam hole 1 along with this water.
0 to the outside of the steam generation chamber 9.

That is, by repeating the above operations, it is possible to prevent the accumulation of water scale and eliminate the harmful effects caused by the accumulation.

Note that this invention is not limited to the above-mentioned embodiment; for example, the shape of the draining plate can be modified in various ways, such as a rectangular shape, in addition to a dish shape that forms part of a spherical surface, depending on the shape of the steam generation chamber.

Furthermore, if the drip valve is constructed to open when the valve body is lowered, the inversion state of the water receiving plate may be reversed to that of the above embodiment.

This invention has been explained above, and since the opening/closing operation of the dripping valve is linked to the reversing operation of the water receiving plate housed in the steam generation chamber, the dripping valve will not open until the base temperature reaches a predetermined temperature. Therefore, there is no leakage of water from the tank, which prevents corrosion and prevents inconveniences such as leakage of fabrics, etc., and steam can be automatically spewed out when the base temperature reaches a predetermined temperature, so there is no misoperation.

Since the water scale is peeled off each time by the reversing operation of the water receiving plate, it is possible to eliminate the harmful effects caused by the accumulation of water scale.
