Light-promoted stain removal system

Abstract

Stain removal system (101) for treating a stained area (102) on a cloth (103), said stain removal system (101) comprises a container (104) for containing a bleach chemical, wherein the container (104) is a removable cartridge, a system (105) for carrying the bleach chemical to the stained area under a liquid form, and a light source (106) for generating light radiation (107) over the stained area (102).

1 . A stain removal system for treating a stained area on a cloth, the stain removal system comprising:
 a container for containing a bleach chemical, wherein the container is a removable cartridge;   a system for carrying the bleach chemical to the stained area under a liquid form; and   a light source for generating light radiation over the stained area.   
     
     
         2 . The stain removal system as claimed in  claim 1 , wherein said light source is a light emitting diode (LED). 
     
     
         3 . The stain removal system as claimed in any  claim 1 , wherein said light source is adapted to generate said light radiation in a blue spectrum. 
     
     
         4 . The stain removal system as claimed in  claim 1 , wherein said light source has a power larger than 50 mW, preferably larger than 500 mW. 
     
     
         5 . The stain removal system as claimed in  claim 1 , wherein the light source is arranged at a front end of the stain removal system. 
     
     
         6 . The stain removal system as claimed in  claim 1 , wherein the distance between center central part of the light source and center central part of the front end of the system has a value less than 10 cm, preferably less than 5 cm. 
     
     
         7 . The stain removal system as claimed in  claim 1 , wherein said system for carrying the bleach chemical comprises:
 a tube and a valve arranged along said tube, and   a tube ( 202 ) and a pump arranged along said tube.   
     
     
         8 . The stain removal system as claimed in  claim 1 , wherein said container is adapted to contain a liquid bleach chemical or a solid bleach chemical. 
     
     
         9 . The stain removal system as claimed in  claim 8 , wherein said container is adapted to contain a solid bleach chemical, and wherein said system further comprises a water reservoir and a water path for carrying water into the container to dissolve the solid bleach chemical. 
     
     
         10 . The stain removal system as claimed in  claim 9 , further comprising a heating system for heating water of said water reservoir, said heating system being taken among:
 a heater in thermal contact with the water reservoir, and   a water channel formed in a heat sink of said light source.   
     
     
         11 . The stain removal system as claimed in  claim 1 , further comprising a heating system for heating the stained area, said heating system being taken among a heater fan and an infra-red lamp. 
     
     
         12 . The stain removal system as claimed in  claim 1 , corresponding to a portable cordless device. 
     
     
         13 . A cartridge forming a container for containing a bleach chemical, the cartridge being adapted to cooperate with a stain removal system as claimed in  claim 1 . 
     
     
         14 . A method of treating a stained area on a cloth by a stain removal system, the method comprising the steps of:
 retrieving a bleach chemical from a container, the container being in the form of a removable cartridge,   carrying the bleach chemical under a liquid form to the stained area,   generating a light radiation over the stained area.
