Method for rinsing fabric in a washer and washer adapted to carry out this method

Abstract

A method of rinsing fabric in a washer having a wash chamber rotatable about a horizontal axis comprises the step of adding water to the wash chamber and spraying the rinse water by recirculating it onto the fabric while spinning the wash chamber at a speed to effect a centrifugal force on the fabric such that the fabric will not tumble within the wash chamber as it spins. The method further comprises at least a last rinsing step in which the rotating speed of the wash chamber is such that the fabric tumbles within the wash chamber and in that the rinsing water is not recirculated and sprayed onto the fabric.

1 . A method of rinsing fabric in a washer having a wash chamber rotatable about a horizontal axis comprising:
 the step of adding water to the wash chamber and spraying the rinse water by recirculating it onto the fabric while spinning the wash chamber at a speed to effect a centrifugal force on the fabric such that the fabric will not tumble within the wash chamber as it spins, wherein   that it comprises at least a last rinsing step in which the rotating speed of the wash chamber is such that the fabric tumbles within the wash chamber and in that the rinsing water is not recirculated and sprayed onto the fabric.   
   
   
       2 . The method according to  claim 1 , wherein the water amount added in the last rinsing step is higher than the water amount used in the previous rinsing steps. 
   
   
       3 . The method according to  claim 1 , wherein that in each rinsing step with recirculation of rinsing water the washing chamber is accelerated to the speed to effect a centrifugal force on the fabric and it is then slowed down in order to allow tumbling of the fabric, such alternating acceleration and slowing down being repeated several times in each rinsing step. 
   
   
       4 . The method according to  claim 3 , wherein the alternating sequence of acceleration and slowing down of the wash chamber is repeated from about 2 to 12 times. 
   
   
       5 . The method according to  claim 3 , wherein it comprises detecting the detergent concentration in the rinsing water, the last rinsing step being carried out when such detergent concentration is lower than a predetermined value.
