Wet cleaning method, and washing machine having a wet-cleaning batch-processing function for same

Abstract

A wet cleaning method is disclosed, which does not use chemicals and still does not contract or crushes lines as in dry cleaning. The wet cleaning method includes steps for folding laundry to clean and putting in a mesh bag, tightening the mesh bag such that the laundry is tightened with compression, putting the laundry under the compression of the mesh bag into a drum of a washing machine, filling up the drum with water and cleaning the laundry in the drum, and rinsing the cleaned laundry.

         5 . The wet cleaning method of  claim 1 , wherein the step for rinsing is repeated two or more times. 
     
     
         6 . The wet cleaning method of  claim 5 , wherein the step for rinsing is repeated 3 times. 
     
     
         7 . The wet cleaning method of  claim 2 , wherein the step for spin-drying is performed with a low RPM of the washing machine below about 600, preferably about 500. 
     
     
         8 . The wet cleaning method of  claim 2 , wherein the overall time for the step for spin-drying is not exceeding 1 minute, and the step for spin-drying increases the RPM of the washing machine slowly, stay at the maximum speed for 5 to 10 seconds, decreases the RPM and stop in order. 
     
     
         9 . A washing machine having a batch processing function of wet cleaning comprising a drum installed rotatably, a motor for rotating the drum, a load portion having a water-supplying valve and a water-draining pump or a water-draining valve, a key input for a user's inputting information, a memory for storing a washing machine-operating algorithm and cleaning related information, a display for displaying information regarding cleaning according to input data from the key input, and a controller for controlling operations of the load portion by outputting control signals to a driver for driving the load portion, the memory, and the display according to data inputted from the key input,
 wherein the memory stores wet cleaning data comprising a cleaning data for filling water the drum and cleaning the laundry received in the drum, a rinsing data for rinsing the cleaned laundry, and a spin-drying data for spin-drying the rinsed laundry,   wherein the rinsing data comprises data for performing the step for rinsing,   wherein the key input comprises a wet cleaning selector for the user to select the wet cleaning,   wherein the washing machine is configured, such that if a wet cleaning starting key is pressed when the wet cleaning selector is chosen after putting the laundry to clean into a mesh bag, making the laundry received in the mesh bag compressed by tightening the mesh bag, and putting the laundry into the drum of the washing machine, the wet cleaning data stored in the memory are read out by the controller, and the load portion is controlled by the read-out wet cleaning data, so as to perform the steps for cleaning, rinsing, and spin-drying in batch.   
     
     
         10 . The washing machine having a batch processing function of wet cleaning of  claim 9 , wherein the cleaning data comprises data for the step for cleaning for 2 to 10 minutes according to kinds of fabric and states of the laundries in a cold water. 
     
     
         11 . The washing machine having a batch processing function of wet cleaning of  claim 9 , wherein the spin-drying data comprises data for spin-drying performed with a low RPM of the washing machine below about 600, preferably about 500. 
     
     
         12 .
