Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a steam system that can switch between steam and dry mode and flush out impurities such as lint that have accumulated in the steam passage by pouring a large amount of water from the tank into the vaporization chamber of the base. It is related to irons and aims to reduce costs by simplifying the configuration.

Generally, a steam iron with this type of cleaning function has a relatively large opening in the tank, and a normally closed drain valve is disposed in this opening, and when the drain valve is opened, a large amount of water-based steam is discharged from the opening. It was designed to be poured into the passage to clean the inside of the steam passage.

For this reason, a special opening for cleaning must be provided in the tank, and a drain valve to open and close this opening, as well as an operating rod to open and close this drain valve, etc. must be provided, making the configuration complicated. This caused the problem of high costs.

The present invention eliminates these conventional problems, and one embodiment thereof will be described below with reference to the drawings.

In the figure, 1 is a base with a heater 2, and a vaporization chamber 3.
have.

Reference numeral 4 denotes a steam passage communicating with the vaporization chamber 3, and is provided with a large number of steam ejection holes 5 that open on the shaded side of the base.

Reference numeral 6 denotes a penis lid installed on the base 1, which defines the vaporization chamber 3 and the steam passage 4.

A tank 7 is installed on the base lid 6, and has an opening 8 at the bottom for attaching a nozzle part.

Reference numeral 9 denotes a nozzle portion disposed in opposition to the mouth edge of the opening 8 on the side of the vaporizing chamber, and is brought into pressure contact with the opening edge by a spring 11.

Note that the opening 8 is formed larger than the nozzle hole 10 of the nozzle portion 9.

Reference numeral 12 denotes an opening/closing rod that is movable up and down in the tank 7 with its lower end facing the nozzle part 9. It is constantly pushed upward by a spring 13, and a spring 14 is installed at the tip of the opening/closing rod 12. An auxiliary opening/closing rod 15 is attached to allow for appropriate stroke expansion and contraction.

The auxiliary opening/closing rod 15 is fixed to the opening/closing rod 12 by a pin or the like so as to be vertically movable, and is normally configured to move up and down together with the opening/closing rod 12.

Further, the load of the spring 14 is set to be smaller than that of the spring 11.

Reference numeral 17 denotes a steam button for vertically operating the opening/closing rod 12 from the outside, and by pressing the steam button, the opening/closing rod can be switched to three levels of suppression.

In the above configuration, the following operation will be explained.

First, when using a normal iron, when the steam button 17 is set to the highest position as shown in Figure 1, the opening/closing rod 12
is raised by the spring 13 together with the connecting rod 15,
Open the hole 10 of the nozzle part 9.

Therefore, the water in the tank 7 drips into the vaporization chamber 3 from this nozzle hole 10 and is vaporized.

Then, it is ejected from the steam ejection hole 5 via the steam passage 4.

Next, when switching to dry mode or pouring mode during this ironing operation, press the steam button 17 to the "I" position and close the nozzle hole 10 as shown in FIG. 2A.

At this time, the opening/closing rod 12 of this embodiment is provided with an auxiliary opening/closing rod 15 at its lower end so that it can be expanded and contracted.
(Even if the opening/closing rod 12 is pressed excessively, the nozzle part 9 will not be pushed down and the opening 8 will open. This has the advantage that it can be used with peace of mind.

Although it is normally used as described above, cleaning is performed by pushing the steam button 17 to the state shown in FIG. 2 α.

That is, when the opening/closing rod 12 is further pushed down to the position α from the dry state, the auxiliary opening/closing rod 15 is pressed while in contact with the nozzle part 9, as shown by the opening in FIG. 2, and the spring is completely compressed, causing the opening/closing The rod 12 and the auxiliary opening/closing rod 15 are substantially integrated to push down the nozzle portion 9 against the urging force of the spring 11.

As a result, the opening 8 that has been blocked by the nozzle portion 9 is opened, and a large amount of water in the tank 7 is discharged from the opening 8 into the vaporization chamber 3.

Part of this water is vaporized to become high-pressure steam, which is vigorously discharged from the vaporizing chamber 3 through the steam passage 4 and from the steam jet hole 5.

At this time, the water from the tank performs a cleaning action by washing away impurities such as limescale that have adhered to the vaporization chamber 3, steam passage 4, etc.

In the above embodiment, the nozzle part 9 was moved toward the vaporization chamber, but the opening 8 may be opened by moving it upward, and the spring 11 supporting the nozzle part is directly attached to the base. Needless to say, it may be constructed between the

As is clear from the above description of the embodiments, according to the present invention, the nozzle moves to open the bottom of the tank, so there is no need for a cleaning opening or a drain valve to open and close the opening. It is possible to simplify the configuration and reduce costs.

Moreover, as shown in this embodiment, if the nozzle section is moved toward the vaporization chamber and pushed up by the opening/closing rod, no special member is required for moving the nozzle section, and the structure can be further improved. simplification and cost reduction.
