Description

[Detailed explanation of the idea] Industrial applications This invention relates to a steam iron for commercial use.

Prior Art In the conventional steam iron of this type, steam is directly fed from a separately provided boiler and is ejected from numerous spout holes provided in the bottom plate.

Problems with the Prior Art In conventional steam irons, when ironing is not being performed, it is possible to close a valve provided on the steam supply pipe to the iron to stop the ejection of steam from the iron. When the steam supply is stopped, the steam that accumulates in the steam chamber of the iron cools down over time and begins to form water droplets on the bottom metal, and then the valve is opened to supply steam for ironing. Initially, water droplets tended to drip. In order to solve this problem, conventionally the iron was propped up and the valve was left slightly open rather than completely closed even when not ironing, allowing a small amount of steam to escape.

Solution The solution provided by the present invention to solve the above problem is to attach a pipe to the iron to circulate steam and keep the iron warm.

Example: On the bottom plate 1 is a header 2 as a steam/water separator.
, a steam chamber 3, and a heat insulation pipe 4 surrounding the steam chamber.
One end of the heat insulation pipe 4 is connected to the boiler 15 via a flexible tube, and the other end is connected to the header 2, so that the steam generated in the boiler passes through the flexible tube and heats the area around the steam room 3. It is designed to be fed into the header 2 through a pipe 4. The header 2 and the steam chamber 3 are connected through an inverted L-shaped pipe 5, and the upper end of the rising part of the pipe 5 is closed or opened with a gasket-like valve 6. When opened, the inside of the header 2 is Steam passes through pipe 5 to steam chamber 3
The water is sent to the base plate 1 and is ejected from numerous ejection holes 7 formed in the base metal 1. The valve 6 is attached to the lower end of the vertical shaft 8, and the compression spring 1 is usually wound around the vertical shaft 9.
0, and closes the upper end of the rising portion of the pipe 5. When lifting the valve 6 and opening the upper end of the rising part, the lever 12 provided on the handle 11 is pressed down. and will be raised. In the figure, 13 is a steam trap, and 14 is a cover that covers the steam chamber and the heat insulating pipe 4.

When ironing, the lever 12 is held down, so that the steam generated in the boiler as described above circulates through the heat insulation pipe 4 and reaches the header 2.
The steam enters the pipe 5 from the upper end of the rising portion thereof, passes through the pipe 5, is sent to the steam chamber 3, and is ejected from the jet hole 7.

When ironing is stopped, the presser foot on the lever 12 is released and the upper end of the rising part of the pipe 5 is closed with the valve 6. This will stop the steam from blowing out, but
Even during the stop period, steam is supplied in accordance with the pressure reduction between the headers due to the moisture discharged from the steam tube 13 and the steam discharged accordingly, and the steam flows through the heat insulation pipe, so that the steam chamber 3
is kept warm.

In the embodiment described above, the heat retaining pipe 4 is arranged so as to surround the steam chamber 3, but it may also be arranged in a V-shape or in a meandering manner inside or outside the steam chamber 3.

Effects As described above, the iron of the present invention is designed so that even when ironing is stopped, steam circulates through the insulation pipe to keep it warm, so the steam chamber is cooled and water droplets adhere to it, and then ironing is stopped. When doing this, it will no longer drip with the steam that is ejected.

Claims (1)

[Scope of utility model registration request] It has a steam chamber that is connected to the boiler via a valve and is provided on the bottom plate. When the valve is opened by operating the valve, the steam generated in the boiler is sent to the steam chamber, and the numerous bubbles formed on the bottom plate are In this steam iron, the steam is ejected from the nozzle, and when the valve is closed, the ejection of steam is stopped. On the bottom metal 1, there is further provided a heat insulating pipe 4, which is connected to the boiler and through which steam always flows, and a valve 6. This steam iron is designed so that the steam chamber 3 can be kept warm by the heat insulation pipe 4 even when the steam iron is closed and the ejection of steam is stopped.
