본 발명은 건조겸용 세탁기에 관한 것으로, 특히 건조 기능을 갖는 드럼세탁기의 건조운전을 포함하는 탈수운전 제어방법에 관한 것이다.The present invention relates to a dry washing machine, and more particularly, to a dehydration operation control method including a drying operation of a drum washing machine having a drying function.

일반적으로, 드럼세탁기는 세제와 세탁수 및 세탁물이 드럼 내에 투입된 상태에서, 모터부의 구동력을 전달받아 회전하는 드럼과 세탁물의 마찰력을 이용하여 세탁을 행하는 방식으로서, 세탁물의 손상이 적고, 세탁물이 잘 엉키지 않으며, 두 드리고 비벼빠는 세탁효과를 낼 수 있도록 한 것이다.In general, the drum washing machine is a method of washing the laundry by using the friction force of the rotating drum and the laundry by receiving the driving force of the motor unit in the state in which detergent, washing water and laundry are put into the drum. Don't get tangled, knock and rub to make the laundry effect.

또한, 이러한 드럼세탁기의 기능향상 및 고급화 추세에 따라 드럼세탁기에 세탁물의 세탁 및 탈수 기능 뿐만 아니라 건조 기능까지 수행할 수 있도록 한 건조 겸용 드럼세탁기의 수요도 증가하는 추세에 있다.In addition, in accordance with the trend of functional improvement and high-end of the drum washing machine, there is a trend of increasing the demand of the combined drum washing machine which can perform the washing and dehydration function of the laundry in the drum washing machine as well as the drying function.

이와 같은 건조 겸용 드럼세탁기는 터브의 외측에 설치되는 팬과 건조히터로 외부 공기를 강제 인입하여 가열하고, 가열된 고온의 공기를 터브 내부로 송풍시킴으로써 세탁물을 건조시키게 된다. Such a combined drum washing machine forcibly draws outside air into a fan and a drying heater installed outside the tub, heats it, and blows the heated hot air into the tub to dry the laundry.

첨부된 도면의 도 1과 도 2는 이러한 건조겸용 드럼세탁기의 구성의 일례를 개략적으로 나타낸 도면으로, 캐비닛(1) 내측에 원통형의 터브(2; tub)가 설치되고, 상기 터브(2)의 내측에는 후방의 구동축(4)이 모터(5)에 연결되어 모터(5)의 동력을 전달받아 회전하게 되는 원통형의 드럼(3)이 설치된다. 상기 드럼(3)의 외주면에는 공기 및 세탁수가 통과할 수 있도록 복수개의 통공(미도시)들이 형성된다. 1 and 2 of the accompanying drawings schematically show an example of the configuration of such a combined drum washing machine, a tub (2; tub) is installed inside the cabinet (1), the tub (2) of the Inside the rear drive shaft 4 is connected to the motor 5 is a cylindrical drum (3) which is rotated by receiving the power of the motor (5) is installed. A plurality of through holes (not shown) are formed on the outer circumferential surface of the drum 3 to allow air and washing water to pass therethrough.

그리고, 상기 드럼세탁기의 건조행정을 수행하기 위하여, 상기 터브(2)의 일측 하부 및 상단부에 순환덕트(6)의 양단부가 각각 연결되어 가열 공기의 순환유로를 구성하고, 상기 순환덕트(6)의 내부에는 공기를 강제 순환시키는 송풍팬(7) 및 이 송풍팬(7)에 의해 송풍되는 공기를 가열하는 건조히터(8)가 설치된다. In addition, in order to perform the drying operation of the drum washing machine, both ends of the circulation duct 6 are respectively connected to one side lower part and the upper end of the tub 2 to constitute a circulation flow path of the heating air, and the circulation duct 6 The blower fan 7 forcibly circulating the air and the drying heater 8 for heating the air blown by the blower fan 7 are installed in the interior thereof.

또한, 상기 순환덕트(6)의 상측에는 외부로부터 순환덕트(6) 내로 응축을 위한 냉각수를 공급하기 위한 냉각수 공급관(9)이 연결된다. In addition, the upper side of the circulation duct 6 is connected to a cooling water supply pipe 9 for supplying cooling water for condensation into the circulation duct 6 from the outside.

또한, 상기 터브(2) 내부에는 터브 내의 온도를 감지하는 터브온도센서(B)가 설치되고, 상기 순환덕트(6) 내부에는 순환 공기의 온도를 감지하는 덕트온도센서(A)가 설치된다.In addition, a tub temperature sensor (B) for detecting a temperature in the tub is installed inside the tub (2), and a duct temperature sensor (A) for detecting a temperature of circulating air is installed in the circulation duct (6).

상기와 같이 구성된 종래의 일반적인 건조겸용 드럼세탁기에서 건조행정은 다음과 같은 순서로 이루어진다. In the conventional general drying drum washing machine configured as described above, the drying operation is made in the following order.

탈수행정이 종료되고 건조행정으로 진입하면, 송풍팬(7)이 작동하여 순환덕트(6) 내부로 공기가 유동하게 된다. 순환덕트(6) 내부로 유동하는 공기는 건조히터(8)를 지나면서 고온으로 가열된 후 터브(2) 및 드럼(3) 내부로 유입되어 드럼(3) 내부의 세탁물과 열교환되면서 세탁물을 건조시킨다. When the dehydration stroke is finished and enters the drying stroke, the blower fan 7 is operated to allow air to flow into the circulation duct 6. The air flowing into the circulation duct 6 is heated to a high temperature through the drying heater 8 and then flows into the tub 2 and the drum 3 to heat the laundry while drying the laundry inside the drum 3. Let's do it.

터브(2) 내부에서 세탁물과 열교환된 다습한 공기는 송풍팬(7)의 작동에 의해 다시 순환덕트(6) 내부로 유입되는데, 고온다습한 공기가 바로 송풍팬(7)을 거쳐 건조히터(8)로 유입될 경우 송풍팬(7)의 성능을 저하시키고 건조히터(8)의 효율을 크게 저하시키게 되므로, 상기 냉각수 공급관(9)으로부터 냉각수가 공급되어 터브(2)를 통해 유입된 고온다습한 공기를 응축시켜 습기를 제거하게 된다. The humid air heat-exchanged with the laundry in the tub (2) is introduced into the circulation duct (6) again by the operation of the blowing fan (7), the hot and humid air immediately passes through the blowing fan (7) drying heater ( 8, since the performance of the blower fan (7) and the efficiency of the drying heater (8) is greatly reduced, the coolant is supplied from the cooling water supply pipe (9) and the high temperature and humidity introduced through the tub (2) The air is condensed to remove moisture.

습기가 제거된 공기는 다시 건조히터(8)를 거쳐 고온으로 가열된 후 다시 터브(2) 내로 유입되어 세탁물을 건조시키는 순환과정을 반복하게 된다. After the moisture is removed, the air is heated again to a high temperature through the drying heater 8 and then flows into the tub 2 again to repeat the cycle of drying the laundry.

이와 같이 건조과정에서 고온의 열풍을 터브 내부로 순환시킬 때, 상기 모터(5)는 대략 50RPM 정도의 회전수로 드럼(3)을 저속 회전시키며 고온의 공기가 세탁물에 대체로 고르게 접촉하도록 한다. As such, when the hot hot air is circulated in the tub during the drying process, the motor 5 rotates the drum 3 at a low speed of about 50 RPM and allows the hot air to contact the laundry substantially evenly.

통상적으로, 종래의 건조 겸용 드럼세탁기에서는 각 건조모드에서 상기 덕트 온도센서(A)에 의해 감지된 온도(TA)와 터브 온도센서(B)에 의해 감지된 온도(TB)와의 차이(TA-TB=TC) 가 소정치 이상이거나, 덕트 온도센서(A)에 의해 감지된 온도(TA) 또는 터브 온도센서(B)에 의해 감지된 온도(TB)가 설정치 이상일 때, 혹은 건조행정 시작후 소정 시간이 경과하게 되면, 건조히터(8)의 작용을 중지시키고 송풍팬(7)만을 소정 시간 동안 작동시켜 냉풍건조를 수행하거나, 소정 시간정도 더 건조과정을 수행한 후 건조행정을 중지시키게 된다. In general, in the conventional drying drum washing machine, the difference between the temperature T A sensed by the duct temperature sensor A and the temperature T B sensed by the tub temperature sensor B in each drying mode T When A -T B = T C ) is greater than or equal to a predetermined value, or the temperature T A sensed by the duct temperature sensor A or the temperature T B sensed by the tub temperature sensor B is greater than or equal to the set value, Alternatively, if a predetermined time elapses after the start of the drying stroke, the operation of the drying heater 8 is stopped and only the blower fan 7 is operated for a predetermined time to perform cold air drying, or the drying process is performed for a predetermined time. The administration is suspended.

그러나, 이와 같은 종래의 건조겸용 드럼세탁기는, 탈수행정에서는 탈수만을 수행하고, 탈수행정이 완전히 완료된 다음에야 건조행정에 진입하여 건조를 시작하기 때문에 건조시간이 매우 길어지게 되는 단점이 있었다.However, such a conventional drying drum washing machine has a disadvantage in that the drying time becomes very long because only the dehydration is performed in the dehydration stroke, and only after the dehydration stroke is completely completed, the drying washing machine enters the drying stroke and starts drying.

즉, 드럼세탁기에 적용되는 기존의 건조방식은 탈수행정이 진행되는 동안에는 순수하게 탈수만 이루어질 뿐, 건조가 전혀 이루어지지 않기 때문에 그만큼 건조시간이 길어지게 되는데, 이는 높은 건조성능을 요구하는 최근의 추세에 부합하지 못하는 단점이 있다.In other words, the conventional drying method applied to the drum washing machine is purely dehydrated only during the dehydration stroke, and the drying time is long because the drying is not performed at all, which is a recent trend requiring high drying performance. There is a disadvantage that does not match.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 건조행정에 앞서 수행되는 탈수행정 진행시, 예비건조(豫備乾燥: pre-heat)가 이루어지도록 하여, 탈수행정 완료후에 행해지는 본격적인 건조시간이 단축될 수 있도록 함과 더불어, 상기한 예비건조 진행시 증기가 세제통 쪽으로 빠져나가지 못하도록 하는 드럼세탁기의 탈수운전 제어방법을 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, during the dehydration administration to be carried out prior to the drying administration, the pre-heat (가: pre-heat) is made, the full-scale drying performed after the completion of the dehydration administration In addition to shortening the time, it is an object of the present invention to provide a method for controlling the dehydration operation of the drum washing machine to prevent steam from escaping to the detergent container during the preliminary drying process.

상기한 목적을 달성하기 위해 본 발명은, 공기를 가열하여 고온으로 만드는 건조히터와, 상기 고온의 공기가 열풍공급 유로를 통해 드럼 내부로 강제공급되도록 하는 송풍팬과, 상기 열풍공급유로를 이루는 순환덕트와, 상기 순환덕트 상에 설치되어 상기 순환덕트로 유동하는 고온다습한 공기가 응축되도록 냉각수를 공급하는 냉각수 공급관이 구비되며, 세탁행정, 헹굼행정, 탈수행정 및 건조행정을 순차적으로 수행하는 드럼세탁기의 탈수운전 제어방법에 있어서; 건조행정 진행에 앞서 수행되는 탈수행정 진행시, 건조히터를 오프시킨 상태에서 드럼의 편심 및 거품 감지가 이루어진 후 적어도 한번 이상 일정 속도로 정속 회전하는 탈수 구간에서 소정 시간동안 건조히터를 온시켜 세탁물에 대한 탈수와 더불어 건조를 진행하는 예비건조구간을 갖도록 함과 더불어 탈수행정 수행시 냉각수 공급관을 통해 상기 순환덕트 내부로 응축을 위한 냉각수가 공급되도록 한 것을 특징으로 한다.In order to achieve the above object, the present invention, a drying heater for heating the air to a high temperature, a blowing fan for forced supply of the hot air into the drum through the hot air supply passage, and the circulation forming the hot air supply passage It is provided with a duct and a cooling water supply pipe for supplying cooling water to condense the hot and humid air flowing in the circulation duct is provided on the circulation duct, drum for sequentially performing the washing stroke, rinsing stroke, dehydration stroke and drying stroke In the dewatering operation control method of the washing machine; During the dehydration operation performed prior to the drying administration, the drying heater is turned on for a predetermined time in a dehydration section that rotates at a constant speed at least once after the eccentricity and foam detection of the drum is made while the drying heater is turned off. In addition to having a pre-drying section for drying with the dehydration for the dehydration, characterized in that the cooling water for condensation is supplied into the circulation duct through the cooling water supply pipe during the dehydration administration.

The cooling water for condensation is supplied into the circulation duct 6 through the supply pipe 9.

이 때, 상기 예비건조구간은 탈수속도가 소정의 속도, 예를 들어 600rpm, 이상으로 된 이후에 존재하게 되며, 특히, 상기 예비건조구간은 정속으로 회전하는 구간을 포함한다.At this time, the preliminary drying section is present after the dehydration speed becomes a predetermined speed, for example, 600rpm, or more, in particular, the preliminary drying section includes a section that rotates at a constant speed.

한편, 상기 예비건조구간은 실제적인 편심량 검출이 끝난 이후에 존재하게 된다.On the other hand, the preliminary drying section is present after the actual eccentricity detection is over.

그리고, 상기와 같이 예비운전을 포함한 탈수행정이 진행되는 동안, 냉각수는 지속적으로 순환덕트 내부로 급수될 수 있으며, 이와는 달리 일정 주기로 급수될 수 있다.In addition, during the dehydration operation including the preliminary operation as described above, the cooling water may be continuously supplied into the circulation duct, and alternatively, the cooling water may be supplied at regular intervals.

이 때, 상기 냉각수는 분(分)당 약 0.5리터 정도 급수됨이 바람직하다.At this time, the cooling water is preferably supplied about 0.5 liters per minute.

한편, 상기 냉각수는 예비건조가 수행되는 구간에만 지속적으로 혹은 일정주기로 급수될 수도 있다.On the other hand, the cooling water may be supplied continuously or at regular intervals only to a section where preliminary drying is performed.

먼저, 탈수행정 진행 초기에는 600rpm 이하에서 편심 및 거품감지를 행하게 되는데, 이 때에는 건조히터(8)를 오프시킴으로써 예비건조를 수행하지 않는다.First, eccentricity and bubble detection are performed at the initial stage of the dehydration stroke at 600 rpm or less. In this case, predrying is not performed by turning off the drying heater 8.

이는 실제 편심량은 탈수속도를 600rpm까지 올렸다가 내린후, 다시 드럼을 회전시켜 편심을 감지하는 구간에서 검출되기 때문이며, 두 번째 편심감지에서도 편심량이 정상으로 판정될 경우에야 비로소 탈수속도를 그 다음 단계의 정속탈수 속도인 900rpm으로 올릴 수 있게 되며, 그 속도구간에서 편심없이 안정적으로 탈수가 이루어질 수 있기 때문이다.This is because the actual amount of eccentricity is detected in the section of detecting the eccentricity by rotating the drum again after raising and lowering the dehydration speed up to 600rpm.In the second eccentricity detection, the dehydration speed is not changed until the eccentricity is determined to be normal. This is because it can be raised to a constant speed dehydration speed of 900rpm, and can be dehydrated stably without eccentricity in the speed section.

또한, 이때에야 비로소 편심없이 안정적으로 탈수가 이루어지므로 인해, 건조히터(8) 및 송풍팬(7)을 작동시켜 예비건조도 수행할 수 있기 때문이다.In addition, since only dehydration can be performed stably without eccentricity at this time, preliminary drying can also be performed by operating the drying heater 8 and the blowing fan 7.

이 후, 소정시간 동안 탈수와 더불어 건조를 행한 후에는 다시 드럼을 정지시키게 되며, 이 때 건조히터 및 송풍팬의 작동도 정지시킨다.After that, after dehydration and drying for a predetermined time, the drum is stopped again, and the operation of the drying heater and the blowing fan is also stopped.

이어, 최종적으로 편심감지 및 거품감지를 수행하고, 그 다음 단계의 탈수속도인 1000rpm까지 상승시켜 소정의 시간동안 정속으로 탈수를 진행하게 되는데, 이 1000rpm으로의 정속운전 구간에 다시 건조히터(8) 및 송풍팬(7)도 온시켜 예비건조를 수행한다.Subsequently, eccentricity detection and foam detection are finally performed, and the dehydration speed of the next stage is increased to 1000 rpm, and dehydration is performed at a constant speed for a predetermined time. The drying heater 8 is again in this constant speed operation section at 1000 rpm. And the blower fan 7 are also turned on to perform preliminary drying.

한편, 1000rpm까지 상승시킨 상태에서 소정의 시간동안 탈수 및 예비건조를 행한 다음에는, 탈수속도를 1400rpm까지 상승시켜 다시 설정된 시간동안 최종탈수속도로 탈수한 후에는 탈수속도를 0으로 떨어뜨리게 되고, 그 이후 포풀림 과정을 진행함으로써 탈수행정을 마무리 짓게 된다.On the other hand, after dehydration and preliminary drying for a predetermined time in the state up to 1000rpm, after the dehydration rate is increased to 1400rpm and dehydrated to the final dehydration rate for a set time again, the dehydration rate is reduced to zero, After that, the dehydration administration is completed by proceeding with the inflated process.

상기한 예비건조구간에서, 건조히터는 일정온도 범위에 들도록 온/오프제어되며, 상기 온도범위는 과열현상이 일어나지 않고 건조성능 또한 저하되지 않는 범위로 정해지게 되는데, 예를 들면, 90℃에서 오프되고 87℃에서 온되도록 제어범위가 정해진다.In the preliminary drying section, the drying heater is controlled on / off so as to fall within a predetermined temperature range, and the temperature range is set to a range in which overheating does not occur and drying performance does not decrease, for example, at 90 ° C. The control range is set to turn on at 87 ° C.

한편, 상기와 같이 탈수행정 진행시 본 발명은 냉각수 공급관(9)을 통해 냉각수가 지속적으로 혹은 주기적으로 순환덕트 내부로 급수되도록 한다.On the other hand, when the dehydration operation proceeds as described above, the present invention allows the cooling water to be continuously or periodically supplied to the circulation duct through the cooling water supply pipe 9.

이는, 상기와 같이 탈수행정 진행시 예비건조가 이루어지는 과정에서 드럼내의 세탁물과의 열교환에 의해 발생된 증기가 세제통 손잡이쪽으로 빠져나가지 못하도록 하기 위함이다.This is to prevent the steam generated by the heat exchange with the laundry in the drum in the process of preliminary drying during the dehydration operation as described above to escape to the handle of the detergent container.

한편, 상기와 같이 하여 탈수행정이 완료된 다음에는 본격적으로 건조만을 행하는 건조행정을 수행하게 된다.On the other hand, after the dehydration stroke is completed as described above, the drying stroke is performed only in earnest.

요컨대, 기존의 탈수운전시에는 순수하게 탈수만 행하였지만, 본 발명에서는 탈수진행시 소정의 구간마다 건조히터(8)를 작동시켜 세탁물에 대한 탈수와 건조를 겸하는 예비건조구간을 갖게 되며, 이와 더불어 냉각수 공급이 이루어져 세제통쪽으로의 증기 배출이 방지된다.In short, in the conventional dehydration operation, purely dehydration was performed, but in the present invention, the drying heater 8 is operated at predetermined intervals during the dehydration operation to have a preliminary drying section that combines dehydration and drying of laundry. Cooling water supply is provided to prevent steam from being discharged to the detergent container.

상기와 같이 이루어지는 본 발명의 탈수운전 제어방법은 드럼세탁기를 그예로 들어 설명하였으나, 이에 한정되지 않고 펄세이터 타입의 세탁기 혹은 그밖에 탈수 및 건조기능을 갖는 세탁기라면 세탁기 타입에 관계없이 모두 적용가능함은 물론이다.The dehydration operation control method of the present invention made as described above has been described by taking a drum washing machine as an example, but not limited to this, any pulsator type washing machine or any other washing machine having a dehydration and drying function may be applied regardless of the washing machine type. to be.

이상에서 설명된 바와 같이, 본 발명은 탈수후 진행되는 본격적인 건조에 앞서 탈수진행시 예비건조(豫備乾燥: pre-heat)가 이루어지도록 한 것이다. As described above, the present invention is to pre-heat (시: pre-heat) is performed during the dehydration prior to full-scale drying proceeds after dehydration.
