Washing machine capable of performing normal washing and intense washing

Abstract

The present disclosure relates to a washing machine capable of performing a normal washing and an intense washing, and includes: a controller in which a plurality of entire washing split regions T obtained by partitioning an entire area of the laundry L on a certain sector basis are stored, and to which a contamination washing split region t corresponding to a contaminated site of the laundry L among the entire washing split regions T is inputted, the contamination washing split region t being subjected to an intense washing; and a washing part including at least one washing nozzle installed to inject the washing water toward each of the entire washing split regions T.

1 . A washing machine for performing a washing by injecting a washing water toward a laundry L while conveying the laundry L, comprising:
 a controller in which a plurality of entire washing split regions T obtained by partitioning an entire area of the laundry L on a certain sector basis are stored, and to which a contamination washing split region t corresponding to a contaminated site of the laundry L among the entire washing split regions T is inputted, the contamination washing split region t being subjected to an intense washing; and   a washing part including at least one washing nozzle installed to inject the washing water toward each of the entire washing split regions T,   wherein, based on a signal from the controller, a normal washing is performed in which the washing water mixed with a general detergent is injected toward the laundry L from the at least one washing nozzle, and the intense washing is performed in which the injection of the general detergent is stopped when the contamination washing split region t of the laundry L passes during the normal washing, and the washing water mixed with a specific detergent is injected toward the contaminated site of the laundry L from the at least one washing nozzle corresponding to the contamination washing split region t.   
     
     
         2 . The washing machine according to  claim 1 , further comprising:
 a general detergent tank  800  installed to supply the general detergent to the at least one washing nozzle; and   at least one specific detergent tank  810  installed to supply the specific detergent to at least one the washing nozzle,   wherein the specific detergent is supplied for a certain period of time when the contaminated site passes in the course of supplying the general detergent to the at least one washing nozzle, and   wherein the at least one specific detergent which is classified according to a contamination type is supplied in response to the signal from the controller.   
     
     
         3 . The washing machine according to  claim 2 , further comprising:
 a sensor or a roller configured to measure a size of the laundry L entering the washing part,   wherein the controller is configured to set a predetermined number of the entire washing split regions T and the contamination washing split region t based on the measured size of the laundry L, and configured to calculate a timing of supplying the specific detergent and a timing of stopping the supply of the specific detergent in consideration of a position of the contamination washing split region t under movement.   
     
     
         4 . The washing machine according to  claim 1 ,
 wherein the washing part further includes at least one installation bar  220  in which the at least one washing nozzle is installed, the at least one installation bar  220  being arranged at regular intervals in a travel direction of the laundry L to intersect the travel direction of the laundry L, and   wherein the specific detergent is supplied to the at least one washing nozzle installed in the at least one installation bar  220 .   
     
     
         5 . The washing machine according to  claim 4 , wherein the washing part comprises:
 a first washing part  200  including at least one of a first washing nozzle A- 1  configured to inject the washing water toward the laundry L conveyed from the feeding part  100 , a soaking tank  210  in which the laundry L passed through the first washing nozzle A- 1  is soaked, a sensor configured to sense the laundry L passed through the first washing nozzle A- 1  or the soaking tank  210 , and a second washing nozzle  320  installed to inject the washing water toward the laundry L; and   a second washing part  300  including a third washing nozzle  410  installed to inject the washing water toward the laundry passed through the first washing part  200 .   
     
     
         6 . The washing machine according to  claim 5 , further comprising: at least one of
 a feeding part  100  including a feeding conveyor installed to feed the laundry placed thereon while being unfolded toward the washing part;   a rinsing part  400  including at least one rinsing nozzle installed to rinse the laundry by injecting a rinsing water toward the laundry passed through the washing part;   a dewatering  500  including upper and lower rollers installed to squeeze the laundry passed through the washing part or the rinsing part  400 ;   a discharging part  600  installed to discharge the laundry passed through the washing part, the rinsing part  400  or the dewatering part  500 ; and   a conveyor installed in the washing part, the rinsing part  400 , the dewatering part  500  or the discharging part  600  to convey the laundry,   wherein the conveyor includes at least one of:   a first conveyor installed to convey the laundry L from the feeding part  100  to the second washing part  300 ;   a second conveyor installed to convey the laundry L from the first washing part  200  to the rinsing part  400 ; and   a third conveyor installed to convey the laundry L from the second washing part  300  to the discharging part  600  through the dewatering part  500 , and   wherein the conveyor further includes at least one of: a pair of a second roller R 2  and a first roller R 1  provided adjacent to each other in the first conveyor and the second conveyor so as to invert the laundry to be upside down; and a pair of a second roller R 4  and a third roller R 3  provided adjacent to each other in the second conveyor and the third conveyor so as to invert the laundry to be upside down.
