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 sent directly into the steam chamber from a separately installed boiler, and is then jetted out from numerous spout holes provided in the bottom plate.

Problems with the prior art With conventional steam irons, when ironing is not being performed, the steam from the iron can be stopped by closing a valve installed on the steam supply pipe to the iron. When the valve is closed to stop the supply of steam, the steam accumulated in the supply pipe from the valve to the steam chamber and in the steam chamber cools down over time and becomes water droplets, which adhere to the inner wall surface. In addition, in the supply pipe between the valve and the boiler, when the length of the pipe reaches tens of meters or more in large-scale factories, the steam in the supply pipe near the valve is cooled, and water droplets form on the inner wall of the pipe. It becomes attached. In this state, when the valve is opened to perform ironing next time, the water droplets that have accumulated in the supply pipe and the steam chamber are discharged from the spout hole and scattered together with the steam.

Solution The above problem is solved by providing a steam separator on the bottom plate.

Embodiment A header 2 as a steam/water separator and a steam chamber 3 connected to a boiler (not shown) are provided on the bottom plate 1, and both are communicated with each other by an inverted L-shaped pipe 4. The upper end of the vertical part is closed or opened with a gasket-like valve 5, and the valve 5 is biased downward by a compression spring 7 attached to a vertical shaft 6 on which the valve is attached. It always acts to block the top end of the pipe.

When lifting the valve 5 and opening the upper end of the pipe, this is done by pressing a lever 9 provided on the handle 8. When the lever is pressed, the vertical shaft 6 rises via the link mechanism 11 against the action of the compression spring. .

When the upper end of the pipe is opened, the steam in the header supplied from the boiler through the supply pipe 14 is sent to the steam chamber through the pipe 4, and the bottom metal 1
The steam is ejected from countless steam ejection holes 10 formed in the air. In the figure, 12 is a steam trap, and 13 is a cover.

When ironing is performed, the lever 9 is pressed as described above to blow out steam, and when ironing is to be stopped, the pressure on the lever 9 is released and the upper end of the pipe is closed with the valve 5. This stops the steam ejection, but even during the stop period, steam is supplied in proportion to the reduced pressure inside the header due to the moisture discharged from the steam trap 12 and the steam discharged a little along with this. The header 2 is kept warm, and the bottom metal 1 is mainly welded to the header.
Through this, the steam chamber 3 is also kept warm to some extent.

Effects As described above, with the iron of the present invention, steam is supplied into the header through the supply pipe even when ironing is stopped, so the header is kept warm.
Along with this, the steam chamber is also kept warm, which prevents the steam in the steam chamber from turning into water droplets due to cooling.Moreover, the steam does not accumulate in the supply pipes, and therefore the steam does not turn into water droplets due to cooling inside the supply pipes. Not only is this prevented, but even if the product cools down and becomes water droplets, the water is separated in the header and discharged through the steam trap, so there is no chance of water being spewed out and scattered with steam at the beginning of ironing. It will be resolved.

Claims (1)

[Scope of utility model registration request] A steam chamber 3 provided on the bottom plate 1, a steam separation chamber 2 connected to the boiler, and a steam flow path from the steam separation chamber to the steam chamber, and the flow path is opened and closed by external operation. It consists of a valve 5 and a steam trap 12 installed in a steam/water separation chamber.
When the valve 5 is opened, the steam sent from the boiler to the steam-water separation chamber is passed through the steam chamber and is ejected from the numerous jetting holes 10 formed in the bottom plate 1. When the valve 5 is closed, the steam is sent from the steam trap 12. A steam iron in which steam is supplied to a steam/water separation chamber according to the amount of pressure reduced by the discharged moisture and steam.
