Description:
This application claims the benefit of the Patent Korean Application No. P2004-91272 and p2004-91273 both filed on Nov. 10, 2004, which is hereby incorporated by reference as if fully set forth herein. 
   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a combination dryer, and more particularly, to a new type of a combination dryer which enables air in a drying drum and a cabinet to circulate continuously for drying the laundry more smoothly and which is suitable for being built-in as well as preventing changes of interior environments. 
   2. Discussion of the Related Art 
   In general, a dryer is an electric home appliance which can dry cloth items, cloths and beddings (hereinafter, ‘the laundry’). The dryer dries the laundry by supplying hot air to the washed laundry continuously. 
     FIG. 1  illustrates a conventional tumble dryer out of related art dryers. 
   The related art tumble dryer includes a body  101  a drying drum  20 , a door  40 , a motor  50 , a drying heater  60  and a fan  70 . 
   The body  10  defines an exterior of the tumble dryer and the drying drum  20  is rotatably mounted inside of the body  10 . 
   Also, an opening  11  is formed in front of the body  10 , and the door  40  is coupled for opening/closing the opening  11 . 
   The motor  50  is secured to an inner downside of the body  10  for creating a driving force to rotate the drying drum  20  and the fan  70 . 
   The drying heater  60  is mounted on an inner portion of a hot air supply channel  91  for heating air flowing within the hot air supply channel  91 . The hot air supply channel  91  guides a hot air passage supplied into the drying drum  20 . 
   The fan  70  discharges dry air flowing inside of the drying drum  10  to an outside, and is provided in communication with a hot air discharge channel  92 . 
   Thus, once the fan  70  is put into operation, external air is guided by the hot air supply channel  91  and heated by passing through the drying heater  60  to be drawl into the drying drum  10 . 
   Thereby, the damp laundry introduced into the drying drum  10  is getting dried by the heated external air gradually. 
   The air having dried the laundry by being circulated within the drying drum  10  is guided by the hot air supplying channel  92  to be discharged outside. 
   Once drying is completed by the repeated performance of the above process, the fan  70  and the drying heater  60  are stopped to finish a drying cycle. 
   However, the related art tumble dryer has a problem that a tangled portion of the laundry is not dried smoothly, because the drying cycle is performed in a state of the laundry being introduced together at one time. 
   There is another problem that it is impossible to keep the laundry for a long time in the related art tumble dryer. 
   Thus, recently demands have been increasing accordingly for a new type of a combination dryer having a drying capacity thereof enlarged as well as capable of keeping the laundry for a long time. There are various combination dryers provided with tumble dryers having auxiliary cabinet dryers provided therewith, for example, U.S. Pat. No. 2004-0194339 A1 or U.S. Pat. No. 2004-0154194. 
   The above combination dryer has a cabinet dryer provided on a top of a conventional dryer having a rotatory drum. The cabinet dryer has space for the laundry and receives hot air used to dry or keep the laundry for a long time. 
   The cabinet dryer is employed to dry the laundry or keep the laundry therein for a long time after receiving hot air from the tumble dryer. 
   However, the combination dryer described above may cause a problem that the combination dryer cannot be supplied for being built-in, because the air having dried the laundry is discharged outside of the combination dryer. 
   That is, since space for being built-in should be formed large enough to maintain a sufficient distance with a wall for discharging air smoothly, a design of an exterior may deteriorate. 
   Furthermore, since the air discharged from the combination dryer is a high-temperature humid air, internal environment may not be the high temperature humid one which a user does not want. 
   SUMMARY OF THE INVENTION 
   Accordingly, the present invention is directed to a combination dryer and a method thereof that substantially obviates one or more problems due to limitations and disadvantages of the related art. 
   An object of the present invention is to provide a combination dryer that enables air for drying in a tumble dryer and a cabinet dryer to be circulated continuously, such that changes of interior environment are prevented for being built-in. 
   Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings. 
   To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a controlling method of a combination dryer comprises a controlling process for selectively operating a drying cycle and a refreshing cycle.

   DETAILED DESCRIPTION OF THE INVENTION 
   Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. 
   As shown in  FIGS. 2 to 4 , a combination dryer according to a first embodiment of the present invention includes a tumble dryer  100 , a cabinet dryer  200 , and a controller  300 . 
   The tumble dryer  100  performs only a drying cycle of the laundry. The tumble dryer  100  includes a drying drum  110  capable of rotating and agitating, a hot air supplying pipe, a hot air supplying part  130 , and an air condensing part  140 . 
   The hot air supplying pipe as a pipe guiding an inflow of high-temperature hot air is connectedly in communication with inside space of the drying drum  110 , the air condensing part  140  and a cabinet dryer  200 . 
   The hot air supplying pipe includes a first supplying pipe  121  for supplying hot air into the drying drum  110 , a second supplying pipe  122  for receiving and supplying the air having passed through the air condensing part  140  to the first supplying pipe  121 , and a third supplying pipe  123  for receiving and transmitting the air discharged from the drying drum  110  to the air condensing part  140 . 
   A filtering part  124  may be further provided in the third supplying pipe  123  for filtering foreign substances contained in the flowing air. 
   Also, the hot air supplying part  130  is provided in the second supplying pipe  122  for generating hot air. 
   The hot air supplying part  130  includes a drying heater  131  for heating the air flowing inside of the second supplying pipe  122 , a fan  132  for forcibly ventilating the air within the second supplying pipe  122 . 
   Preferably, the fan  132  is provided in a portion of the second supplying pipe  12  where air is drawn into the drying heater  131 . 
   That is for minimizing damage of the fan  132  due to hot air. 
   Also, the air condensing part  140  condenses the air flowing along the hot air supplying pipe to radiate heat of the air. The air condensing part  140  includes a condenser  141  and an air condensing fan  142 . 
   The condenser  141  receives the hot air from the third supplying pipe  123 , and includes a pipe having a plurality of branched portions and a cooling pin. 
   The air condensing fan  142  ventilates external air toward the condenser  141 . 
   Thus, the humid air passing through the condenser  141  is condensed through heat-exchanging with external air supplied by driving of the air condensing, fan  142 , while flowing along a pipe way of the condenser  141 . 
   The cabinet dryer  200  is mounted on a top of the tumble dryer  100 , with a predetermined space having lots of the laundry kept therein. 
   The cabinet dryer  200  includes a body  210 , a keeping the laundry space  220 , an opening/closing door  230 , a hot air inlet pipe  241 , and an air outlet pipe  242 . 
   The body  210  defines an exterior of the cabinet dryer  200 , and is formed to allow a front thereof to be opened. 
   An extending part  250  may be further provided in the body  210  for extending to reach an inside of the tumble dryer  100 . 
   The extending part  250  is employed for hanging the long laundry such as pants or a coat so that the long laundries may not overlap one another, and preferably extends toward one side so as not to affect rotation of the drying drum  110 . 
   Also, the laundry keeping space  220  forms space for keeping the laundry, and includes a plurality of racks  221  and a bar  222 . 
   At that time, each rack  221  is detachable from the body  210  and formed for seating various kinds of the laundries thereon. The bar  222  is coupled along a front and a rear of a first side of upper space within the body  210 . 
   The opening/closing door  230  is employed for opening/closing the opened front of the body  210 . 
   A first end of the hot air inlet pipe  241  is connected to a portion of the second supplying pipe  122  where air is discharged, and a second end thereof is connectedly in communication with the space  220  keeping the laundry therein for transmitting the hot air from the second supplying pipe  122  into the space  220  keeping the laundry therein. 
   Preferably, an air channel valve  125  may be further provided in the second supplying pipe  122  for choosing and guiding a direction of the air flowing into the first supplying pipe  121  and/or the hot air inlet pipe  241 . 
   Also, a first end of the air outlet pipe  242  is in communication with the laundry keeping space  220 , and a second end thereof is connected to the third supplying pipe  123  to discharge the high-temperature humid air having passed through the laundry within the space  220 . 
   At that time, an auxiliary exhaustion fan (not shown) may be further provided in the air outlet pipe  242 . 
   The controller  300  according to the present invention controls operations of the tumble dryer  100  and the cabinet dryer  200 . 
   At that time, the controller  300  may be provided in at least one of the tumble dryer  100  and the cabinet dryer  200  and it is preferred but not necessary that the controller  300  is provided only in the tumble dryer as shown in embodiments of the present invention. 
   If the controller  300  is provided in both the tumble dryer  100  and the cabinet dryer  200 , the control parts  300  are connected by a data cable (not shown) to make possible to intercommunicate information. 
   Also, the controller  300  may control the tumble dryer  100  and the cabinet dryer  200  respectively, and may control the tumble dryer  100  and the cabinet dryer  200  to communicate each other. 
   A controlling process of a combination dryer according to the present invention will be described. 
   Once a drying cycle is required through the controller  300 , the controller  300  identifies an object of the drying cycle. According to the results of the identification, each various controlling process is performed. 
   The identification of the object is to identify whether only the tumble dryer  100  performs a drying cycle, or only the cabinet dryer  200  performs a drying cycle, or both of the tumble dryer  100  and the cabinet dryer  200  perform each drying cycle. 
   First of all, referring to the flow chart of  FIG. 5 , a controlling process in case that the object of the drying cycle is identified to be only the tumble dryer  100  will be described. 
   If the object of the drying cycle is identified to be only the tumble dryer  100 , an air channel valve  125  is controlled so as to have hot air flow into a first supplying pipe  121 (S 110 ). That is, the hot air is prevented from flowing into the hot air inlet pipe  241 . 
   Under that condition, the drying heater  131  is controlled to be heated. Hence, the air flowing within the second supplying pipe  122  is heated. 
   Also, the fan  132  is controlled to rotate. Hence, the hot air within the second supplying pipe  122  is supplied into the drying drum  110  of the tumble dryer  100  through the first supplying pipe  121  (S 120 ). 
   The hot air within the drying drum  110  is supplied to the laundry within the drying drum  110  for drying the laundry, and continuously discharged to an outside of the drying drum  110  through the third supplying pipe  123 . 
   At that time, the hot air discharged to an outside of the drying drum  110  contains much moisture, as well as the temperature thereof being reduced. 
   Thus, the air containing the much moisture passes through the condenser  141  along the third supplying pipe  123 . 
   At that time, driving of the air condensing fan  142  is controlled. Hence, external air is ventilated toward the condenser  141 . Then, the humid air passing through the condenser  141  heat-exchanges with the external air to be condensed (S 130 ). Thus, the air becomes dry. 
   The dry air having passed through the air condensing part  140  is re-drawn into the second supplying pipe by driving the fan  132 , and passes through the drying heater  131 . 
   Thereby, hot air is continuously created, and the created hot air is supplied into the drying drum  110  to perform a drying cycle repeatedly. 
   Although the user may stop the drying cycle described above at his/her discretion, preferably the drying cycle is performed repeatedly for a predetermined time period. 
   If the drying cycle is performed only for the predetermined time period, it is preferred but not necessary that in a state of stopping the drying heater  131 , not stopping all operations temporarily, air not heated is circulated to reduce a temperature of the drying drum  110 (S 140 ). 
   That is, controlling to continuously drive the fan  132  and the air condensing fan  142  enables the temperature of the drying drum  110  to reach a safe temperature more quickly. 
   That control may be performed until the temperature of the drying drum  110  reach a predetermined temperature, or continuously performed during the predetermined time period. 
   Once the temperature of the drying drum  110  reaches the predetermined temperature, the fan  132  and the air condensing fan  142  are stopped (S 150 ), to finish the drying cycle. 
   Next, referring to a flow chart of  FIG. 6 , a controlling process in case the object of the drying cycle is identified to be only the cabinet dryer will be described in detail. 
   First of all, once the object for drying cycle is identified to be only the cabinet dryer  200 , the air channel valve  125  is controlled so as to make the hot air flow only into the hot air inlet pipe  241  (S 210 ). That is, the hot air is not flown into the first supplying pipe  121 . 
   In that state, the drying heater  131  is controlled to radiate heat for heating the hot air within the second supplying pipe  122 . 
   Also, at that time, the fan  132  is controlled to rotate. Hence, the high temperature air, in other words, the hot air within the second supplying pipe  122  is supplied into the laundry keeping space  220  of the cabinet dryer  200  through the hot air inlet pipe  241  (S 220 ). 
   Thus, the hot air is supplied to the laundry within the laundry keeping space  220  to dry the laundry, and then is transmitted to the third supplying pipe  123  through the air outlet pipe  242 , after being discharged outside of the dryer  200 . 
   The hot air discharged outside of the space  220  may contain a large quantity of moisture, as well as the temperature thereof is reduced, while passing through the laundry. 
   Hence, the air with much moisture passes through the condenser  141  of the air condensing part  140  along the third supplying pipe  123 . 
   At that time, the driving of the condensing fan is controlled. Thereby, external air is drawn toward the condenser  141  and the humid air passing through the condenser  141  heat-exchanges with the external air to be condensed (S 230 ). Thus, the air becomes dry. 
   Continuously, the dry air having passed through the air condensing part  140  is re-drawn into the second supplying pipe  122  by driving the fan  132 , and then passes through the drying heater  131 . 
   Thereby, hot air is generated repeatedly and also the generated hot air is supplied into the laundry keeping space  220  to dry the laundry repeatedly. 
   The drying cycle described above may be stopped by the user at his/her discretion, and preferably the drying cycle is repeated for a predetermined time period. 
   In case the drying cycle is performed for the predetermined time period, preferably it is better to control to reduce the temperature in the laundry keeping space  220  by circulating the air which is not heated in a state of stopping only the drying heater  131 &#39;s radiating heat (S 240 ) than to stop all of the functions temporarily. 
   That is, preferably controlling to drive the fan  132  and the air condensing fan  142  repeatedly allows the temperature of the space  220  to reach a safe temperature more quickly. 
   Preferably, that controlling is performed repeatedly until the temperature of keeping space  220  reaches the predetermined temperature, or during the predetermined time period. 
   Once the temperature of the drying drum  110  reaches the predetermined temperature, the fan  132  and the air condensing fan  142  are stopped (S 250 ) to complete the drying cycle. 
   Next, referring to the flow chart of  FIG. 7 , a controlling process in case the object of the drying cycle is identified to be both of the tumble dryer  100  and the cabinet dryer  200  will be described in detail. 
   First of all, once the object of the drying cycle is identified to be the tumble dryer  100  and the cabinet dryer  200 , the air channel valve  125  is controlled so as to help hot air flow into both of the first supplying pipe  121  and the hot air inlet pipe  141  (S 310 ). 
   In that state, the drying heater  131  is controlled to radiate heat, and then the air within the second supplying pipe  122  is heated. 
   Also, at that time, the fan  132  is controlled to rotate. Hence, the hot air within the second supplying pipe  122  is supplied into the drying drum  110  of the tumble dryer  100  and the laundry keeping, space  220  of the cabinet dryer  200  through the first supplying pipe  121  and the hot air inlet pipe  241  (S 320 ). 
   The hot air within the drying drum  110  and the laundry keeping space  220  is supplies to the laundry within the drying drum  110  and the laundry keeping, space  220  to dry the laundry, and continuously discharged outside of the drying drum  110  and the cabinet dryer  200  through the third supplying pipe  123  and the air outlet pipe  242 . 
   The air discharged through the air outlet pipe  242  is transmitted to the third supplying pipe  123 , and then meets the air flowing along the third supplying pipe  123 . 
   At that time, the hot air discharged outside of the drying drum  110  and the laundry keeping space  220  has the temperature thereof reduced in the middle of passing through the laundry, and maintains a large quantity of moisture. 
   Thus, the air having much moisture passes through the condenser of the air condensing part  140  along the third supplying pipe  123 . 
   At that time, the driving of the air condensing fan  142  is controlled. Thereby, external air is drawn toward the condenser  141 , and the humid air passing through the condenser  141  exchanges heat with the external air to be condensed. Thereby, the air becomes dry. 
   The dry air having passed through the air condensing part  140  is re-drawn into the second supplying pipe  122  by the repeated driving of the fan  132 , and after that passes through the drying heater  131 . 
   Thereby, hot air is created repeatedly, and also the generated hot air is supplied into the drying drum  110  and the laundry keeping space  220  through the first supplying pipe  121  and the hot air inlet pipe  241  so as to perform a drying cycle for the laundry repeatedly. 
   The drying cycle for the laundry described above may be stopped by the user at his/her discretion, and it is preferred but not necessary that the drying cycle is performed for the predetermined time period repeatedly. 
   Preferably, in case the drying cycle is performed for the predetermined time period, it is better to circulate the air not heated for reducing the temperature of the drying drum  110  and the laundry keeping space  220  in a state of stopping the drying heater  131  (S 320 ) than to stop all of the functions temporarily. 
   That is, the fan  132  and the air condensing fan  142  may be controlled to drive continuously so as to help the temperature of the drying drum  110  and the laundry keeping space  220  reach a safe temperature more quickly. 
   Controlling the fan  132  and the air condensing fan  142  to drive continuously may be performed until the temperature of the drying drum  110  and the space  220  reach the predetermined temperature by identifying the temperature repeatedly, or during the predetermined time period. 
   Once the temperature of the drying drum  110  reach the predetermined temperature, the fan  132  and the air condensing fan  142  are stopped (S 350 ) to complete the drying cycle. 
   On the other hand,  FIG. 8  shows a combination dryer according to a second embodiment of the present invention. 
   That is, according to the second embodiment of the present invention, a steam generating part  310  is further provided for generating steam. Also, inner space of the steam generating part  310  and the cabinet dryer  200  is connected by a steam supplying pipe  320 . 
   The steam generating part  310  supplies steam to the laundry kept within the cabinet dryer  200  to have the laundry refreshed, and is provided in at least one of the tumble dryer  100  and the cabinet dryer  200 . 
   The steam generating part  310  includes a water chamber  311  for storing water to generate steam, a water supplying pipe  312  connected to the water chamber  311  for receiving water from the water chamber  311  a heating part  313  having predetermined space for storing the water received from the water supplying pipe  312 , and heating element  314  provided within the heating part  313  for heating and evaporating the water into steam. 
   The water chamber  311  may be connected to the water pipe for receiving water, or the user may supply water to the water chamber  311  directly. 
   Alternatively, as not shown the steam generated in the steam generating part  310  may be supplied to the tumble dryer  100 . 
   A refreshing cycle in the combination dryer according, to the second embodiment of the present invention will be described. 
   First, in case of performing a refreshing cycle such as smoothing out wrinkles and sterilizing the laundry, the steam generating part  310  is operated for generating steam. 
   In other words, the water supplied to the heating part  314  from the water chamber  311  is evaporated by heating the heating element  314  for generating steam. 
   The steam generated in the steam generating part  310  is supplied into the laundry keeping space  220  of the cabinet dryer  200  through the steam supplying pipe  320 . 
   Hence, the refreshing cycle is performed for the laundry kept within the space  220  of the cabinet dryer  200 . 
   On the other hand, the steam generating part  310  according to the second embodiment of the present invention may cause a problem that the user should supply water for generating steam consistently. 
   Furthermore, the first embodiment of the present invention may cause a problem that an auxiliary structure is needed for draining the condensed water, because the air condensing part  140  according to the first embodiment is operated for condensing hot humid air to generate much condensed water. 
   Therefore, a technical feature according to a third embodiment of the present invention is that the condensed water generated in the air condensing part is used to generate steam. 
   That is, as shown in  FIG. 9 , according to a combination dryer of the third embodiment, a condensed water storing chamber  150  is further provided in the combination dryer of the first embodiment. The condensed water storing chamber  150  is connected to the air condensing part  140 , the cabinet dryer  200  and the drain pipe  160 . 
   The condensed water generated in the air condensing part  140  and in the cabinet dryer  200  is drawn into the condensed storing chamber  150  through the drain pipe  160 . 
   Preferably, a pump  161  is further provided in the drain pipe  160  for forcibly pumping the condensed water to transmit the condensed water to the condensed water storing chamber  150 . 
   Also, the combination dryer of the third embodiment further includes a steam generating part  410  for generating steam after receiving the condensed water stored in the condensed water storing chamber  150 , and a steam supplying pipe  420  for supplying the steam generated in the steam generating part  410  to the cabinet dryer  200 . 
   At that time, the steam generating part  410  is provided in either of the tumble dryer  100  and the cabinet dryer  200 , and includes a condensed water supplying pipe  412  for receiving water from the condensed water storing chamber  150 , a heating part  413  having a storing space for contemporarily storing the water received through the condensed water supplying pipe  412 , and a heating element  414  provided within the heating part  413  for heating and evaporating the stored water into steam. 
   Especially, it is preferred but not necessary that an opening/closing valve  415  is further provided in the condensed water supplying pipe  412  for selectively opening/closing the inflow of the water supplied into the heating part  414 . 
   A refreshing cycle of the combination dryer according to the third embodiment of the present invention will be described. 
   First, when operating a refreshing cycle such as smoothing out wrinkles or sterilizing the laundry, an air passage of the condensed water supplying pipe  412  is opened by controlling of the opening/closing valve  415  for supplying the water n the condensed storing chamber  150  to the heating part  413 . 
   Also, heating the heating part  414  evaporates the water supplied to the heating part  413  for generating steam. 
   At that time, the steam generated within the heating part  413  is supplied into the laundry keeping space  220  of the cabinet dryer  200  through the steam supplying pipe  420 . 
   Thus, the laundry within the space  220  is refreshed by the hot steam. 
   Also, preferably the fan  132  is driven for helping the hot humid air within the cabinet dryer  200  flown into the condenser  141 . 
   Hence, condensed water is regularly supplied into the condensed water storing chamber  150 , and steam is generated by using the condensed water without difficulty. 
   The condensed water is generated while the humid air is passing through the condenser of the air condensing part, and the condensed water is supplied into the condensed water storing chamber  150  through the drain pipe  160 . Alternatively, the water remaining within the laundry keeping space  220  of the cabinet dryer  200  may be supplied into the condensed water storing chamber  150 .
