Laundry machine

Abstract

A laundry machine is disclosed. The laundry machine includes a drum in which laundry is put, a steam generator to generate steam, a water supply line connected to the steam generator, a steam line connected to the steam generator, and a valve placed in the steam line, wherein the valve is controlled to block the steam line to prevent water from flowing from the steam generator to the drum.

1 . A laundry machine comprising:
 a drum in which laundry is placed;   a steam generator to generate steam;   a water supply line through which water is supplied to the steam generator;   a steam line through which the generated steam is supplied to the drum; and   a valve positioned in the steam line, wherein the valve is controlled between an open and closed position such that when the valve is in the closed position, the valve prevents communication between the steam generator and the drum.   
   
   
       2 . The laundry machine of  claim 1 , wherein the water supply line is connected to a water supply valve and the water supply valve is connected to a faucet. 
   
   
       3 . The laundry machine of  claim 1 , wherein the valve is controlled based on a temperature of the steam generator. 
   
   
       4 . The laundry machine of  claim 3 , wherein the valve is controlled to the open position when the temperature reaches a preset temperature. 
   
   
       5 . The laundry machine of  claim 4 , wherein the valve is controlled to the closed position when an amount of water supplied to the steam generator reaches a preset amount. 
   
   
       6 . The laundry machine of  claim 2 , wherein the valve is controlled to closed position within a preset period of time after the water supply valve is closed and the valve is controlled to the open position when a temperature of the steam generator reaches a preset temperature. 
   
   
       7 . The laundry machine of  claim 1 , wherein the valve is controlled based on an amount of water supplied to the steam generator. 
   
   
       8 . The laundry machine of  claim 7 , further comprising an instrument to measure an amount of water flowing through the water supply line. 
   
   
       9 . The laundry machine of  claim 8 , wherein the instrument includes an impeller flowmeter. 
   
   
       10 . The laundry machine of  claim 9 , wherein the valve is controlled to the closed position when a rotation number of an impeller of the impeller flowmeter reaches a preset number. 
   
   
       11 . The laundry machine of  claim 8 , wherein the instrument comprises a sensor to sense a water level of the steam generator.
