All steam iron

Abstract

An all steam iron constructed as that a preheat hollow chamber is omitted in an iron main body, and a preheat circulation passage, in which steam flows to heat the iron main body, is formed. And, a branched passage, freely opened and closed by an operation valve, is disposed along a near part of a sole, and steam is jetted out of many steam jets on the sole through the branched passage in a steam jet operation in which the operation valve is opened.

What is claimed is:  
     
         1 . An all steam iron comprising an iron main body in which a heat hollow chamber for preheat is omitted and a preheat circulation passage is formed.  
     
     
         2 . An all steam iron comprising a construction in which: 
 a preheat circulation passage, omitting a heat hollow chamber for preheat, is formed in an iron main body;    the iron main body is warmed by steam flowing in the preheat circulation passage;    a branched passage, freely opened and closed by an operation valve, is disposed along a near portion of a sole; and    the steam is jetted out of many steam jets on the sole through the branched passage in a steam-jetting state in which the operation valve is opened.    
     
     
         3 . An all steam iron comprising an iron main body, having many steam jets disposed on a sole of flat face, many branched passage bores parallel to the sole and communicatively connected to the steam jets, and a preheat circulation passage bore disposed above the branched passage bores, in which the branched passage bores and the preheat circulation passage bore are formed uniformly with a block body.  
     
     
         4 . The all steam iron as set forth in  claim 3 , wherein a steam supplying hose has a first supplying passage and a second supplying passage, the first supplying passage is communicatively connected to the preheat circulation passage bore, the second supplying passage is communicatively connected to an operation valve, and steam can be supplied to the branched passage bores by the operation valve in a steam-jetting state.  
     
     
         5 . The all steam iron as set forth in  claim 4 , wherein a check valve, which sends the steam supplied from the second supplying passage to the preheat circulation passage bore in a non-jetting state and prevents water generated in the preheat circulation passage bore from flowing back to the second supplying passage side in the steam-jetting state, is provided.  
     
     
         6 . The all steam iron as set forth in  claim 1 ,  2 ,  3 ,  4 , or  5 , wherein the iron main body is formed with aluminum, titanium, magnesium, or an alloy of these metals.
