Laundry device and method thereof

Abstract

The present invention relates to a laundry device, and more particular, to a new type of laundry device provided with a washing machine and cabinet dryer as one body for reducing production cost, which can gain suitable output for an operation of each cycle by varying a structure of a drying heater as well as can perform a washing and drying cycle simultaneously.

1 . A laundry device comprising: 
 a washing machine with a drying function comprising a drum, a hot air supplying pipe for guiding hot air inflow into the drum and more than two drying heaters provided within the hot air supplying pipe for heating flowing air;    a cabinet dryer mounted on a top of the washing machine with a drying function comprising a connecting pipe connected with the hot air supplying pipe for drying the laundry therein by receiving air flowing along the hot air supplying pipe; and    a controller provided in at least one of the washing machine and the cabinet dryer for controlling the washing machine with a drying function and the cabinet dryer.    
   
   
       2 . The laundry device of  claim 1 , wherein the drying heaters of the washing machine with a drying function are two, and 
 the two drying heaters having the same output capacity of power are paralleled.    
   
   
       3 . The laundry device of  claim 1 , wherein the drying heaters of the washing machine with a drying function are two, and 
 the two drying heaters having a different output capacity of power are paralleled.    
   
   
       4 . The laundry device of  claim 1 , wherein the drying heaters of the washing machine with a drying function are two, and 
 the two drying heaters having the same output capacity of power are connected so as to adjust linear output.    
   
   
       5 . The laundry device of  claim 1 , wherein the drying heaters of the washing machine with a drying function are two, and 
 the two drying heaters having a different output capacity of power are connected so as to adjust linear output.    
   
   
       6 . The laundry device of  claim 1 , wherein the drying heaters of the washing machine with a drying function are three, and 
 the two drying heaters having the same output capacity of power are connected so as to adjust linear output and the other drying heater parallels the two drying heater.    
   
   
       7 . A method of a laundry device comprising steps of 
 receiving a user's request for a drying cycle;    identifying if an operation object is a washing machine with a drying function and/or a cabinet dryer; and    controlling more than two drying heaters to selectively radiate heat based on the identified operation object.    
   
   
       8 . The method of the laundry device of  claim 7 , wherein all of the drying heaters are controlled to be on in case that the operation object is identified as a washing machine with a drying function.  
   
   
       9 . The method of the laundry device of  claim 7 , wherein one of the drying heaters is controlled to be on in case that the operation object is identified as a cabinet dryer.  
   
   
       10 . The method of the laundry device of  claim 7 , wherein all of the drying heaters is controlled to be on in case that the operation object is identified as both of the washing machine with a drying function and the cabinet dryer.  
   
   
       11 . A laundry device comprising: 
 a drum washing machine only for washing the laundry;    a cabinet dryer mounted on a top of the drum washing machine for drying the laundry, the cabinet dryer comprising a keeping part for keeping the laundry therein, a hot air supplying pipe for guiding hot air inflow, and more than two drying heaters provided within the hot air supplying pipe for forcibly ventilating air; and    a controller provided in at least one of the washing machine and the cabinet dryer for controlling the drum washing machine and the cabinet dryer.    
   
   
       12 . The laundry device of  claim 11 , wherein the drying heaters of the cabinet dryer are two and 
 the two drying heaters having the same output capacity of power are paralleled.    
   
   
       13 . The laundry device of  claim 11 , wherein the drying heaters of the cabinet dryer are two, and 
 the two drying heaters having a different output capacity of power are paralleled.    
   
   
       14 . The laundry device of  claim 11 , wherein the drying heaters of the cabinet dryer are two, and 
 the two drying heaters having the same output capacity of power are connected so as to adjust linear output.    
   
   
       15 . The laundry device of  claim 11 , wherein the drying heaters of the cabinet dryer are two, and 
 the two drying heaters having a different output capacity of power are connected so as to adjust linear output.    
   
   
       16 . The laundry device of  claim 11 , wherein the drying heaters of the cabinet dryer are three, and 
 the two drying heaters having the same output capacity of power are connected so as to adjust linear output and the other drying heater parallels the two drying heater.    
   
   
       17 . A method of a laundry device comprising steps of receiving a user's request for a cycle of a cabinet dryer; 
 identifying if a kind of operation is one of a drying, laundry-keeping and refreshing cycle; and    controlling more than two drying heaters to selectively radiate heat based on the identified kind of the operation.    
   
   
       18 . The method of the laundry device of  claim 17 , wherein all of the drying heaters are controlled to be on in case that the kind of the operation is identified as a drying cycle.  
   
   
       19 . The method of the laundry device of  claim 17 , wherein one of the drying heaters is controlled to be on in case that the kind of the operation is identified as a laundry-keeping cycle.
