본 발명은 드럼세탁기에 관한 것으로 특히, 세탁수 가열을 완료한 후에 열에너지 손실을 줄이기에 적합한 드럼세탁기의 제어방법에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to a control method of a drum washing machine suitable for reducing the heat energy loss after completing the washing water heating.

일반적으로 드럼세탁기는 세제와 세탁수 및 세탁포가 드럼내에 투입된 상태에서 모터의 구동력을 전달받아 회전하는 드럼과 세탁포의 마찰력을 이용하여 세탁을 행하는 방식으로서, 세탁포의 손상이 거의 없고, 세탁포가 서로 엉키지 않으며, 두드리고 비벼빠는 세탁효과를 낼 수 있다.In general, the drum washing machine is a method of washing by using the friction force of the rotating drum and the laundry cloth by receiving the driving force of the motor in the state in which detergent, washing water, and laundry cloth is put into the drum. Don't get tangled with each other, knocking and rubbing can have a laundry effect.

이하, 첨부된 도면을 참조하여 종래 기술을 설명하면 다음과 같다.Hereinafter, the prior art will be described with reference to the accompanying drawings.

도 1은 일반적인 드럼세탁기의 구조도이다.1 is a structural diagram of a general drum washing machine.

도면에 도시된 바와 같이, 드럼세탁기는 하우징(50)과, 상기 하우징(50) 내부에 댐퍼(51) 및 스프링(52)으로 지지되는 터브(53)와, 상기 터브(53) 내면에 회전 가능하게 설치된 드럼(54)과, 상기 드럼(54)에 연결됨과 아울러 모터(55)에 벨트(56)로 연결된 풀리(57)로 구성되어 있다.As shown in the drawing, the drum washing machine is rotatable to the housing 50, the tub 53 supported by the damper 51 and the spring 52 inside the housing 50, and the inner surface of the tub 53 And a pulley 57 connected to the drum 54 and connected to the motor 55 by a belt 56.

또한, 상기 터브(53) 및 드럼(54)에 세탁수를 공급하기 위해 설치된 급수배관(58) 및 급수밸브(59)와, 상기 세탁수가 세탁시 순환되도록 순환펌프(60)를 개재하여 설치된 순환배관(61)과, 상기 순환배관(61)에서 물을 배수시키기 위해 설치된 배수펌프(62)로 구성되어 있다.In addition, the tub 53 and the drum 54 is provided with a water supply pipe 58 and a water supply valve 59 installed to supply the wash water, and the circulation is installed through the circulation pump 60 so that the wash water is circulated during washing It consists of a piping 61 and the drain pump 62 provided in order to drain water from the said circulation pipe 61. As shown in FIG.

특히, 상기 터브(53) 내부에는 세탁수를 가열하기 위하여 히터(63)가 설치되어 있고, 드럼(54)을 간헐 개폐시킬 수 있도록 도어(64)가 설치되어 있으며, 드럼(54)에는 세탁수의 드럼(54) 내부 순환을 위해 리프터(65)가 설치되어 있다.In particular, a heater 63 is installed in the tub 53 to heat the wash water, and a door 64 is installed to intermittently open and close the drum 54, and the wash water is installed in the drum 54. A lifter 65 is installed for circulation of the drum 54.

상기한 드럼세탁기의 동작을 살펴보면 다음과 같다.Looking at the operation of the drum washing machine as follows.

도 2는 종래 기술에 따른 드럼세탁기의 세탁 과정을 나타낸 순서도이다.2 is a flowchart illustrating a washing process of a drum washing machine according to the prior art.

사용자가 세탁을 하기 위하여 도어(64)를 열고 세탁포를 드럼(54) 내부에 투입하고 도어(64)를 닫은 후에 드럼세탁기를 동작시키면 외부로부터 세탁수가 공급되게 된다.When the user opens the door 64 to wash the laundry, inserts the laundry cloth into the drum 54, closes the door 64, and operates the drum washing machine to supply the washing water from the outside.

이후 급수가 완료되면(S201), 모터(55)와 순환펌프(60)가 구동되어 드럼(54)내의 세탁포에 세탁수가 고르게 적셔지게 된다(S202).After the water supply is completed (S201), the motor 55 and the circulation pump 60 is driven so that the washing water is evenly soaked in the laundry cloth in the drum 54 (S202).

즉, 상기 모터(55) 구동에 의해 드럼(54)이 회전되고, 상기 터브(53)의 저면으로 흐르는 세탁수는 순환배관(61)을 통해 순환펌프(60)로 유입되고 순환펌프(60)에 의해 다시 터브(53) 상면으로 강제 순환되어 드럼(54) 내에 뿌려지면서 세탁포에 세탁수가 고르게 적셔지게 된다. That is, the drum 54 is rotated by the driving of the motor 55, and the wash water flowing to the bottom surface of the tub 53 flows into the circulation pump 60 through the circulation pipe 61 and the circulation pump 60. By the forced force circulated back to the upper surface of the tub 53 is sprayed in the drum 54, the washing water is evenly soaked in the laundry cloth.

포적심을 위한 설정 시간이 지나면 히터(63)에 전원을 인가하여 세탁수를 설정 온도까지 가열하는 히팅(heating) 동작을 실시한다(S203). After the set time for the core, the heater 63 is supplied with power to perform a heating operation for heating the washing water to the set temperature (S203).

그리고, 세탁수가 설정 온도에 도달하였는지를 실시간으로 감지하여 히팅 동작 완료 여부를 판단한다(S204). Then, the washing water reaches the set temperature in real time to determine whether the heating operation is completed (S204).

세탁수가 설정 온도에 도달하지 못하였으면 히팅 동작이 완료되지 않은 것으로 판단하고 상기 스텝 203(S203)으로 리턴한다. If the wash water does not reach the set temperature, it is determined that the heating operation is not completed, and returns to step 203 (S203).

반면, 세탁수가 설정 온도에 도달하였으면 히팅 동작이 완료된 것으로 판단하고 순환펌프 및 모터를 구동시켜 본격적인 세탁을 진행한다(S205).On the other hand, when the washing water reaches the set temperature, it is determined that the heating operation is completed, and proceeds to full-scale washing by driving the circulation pump and the motor (S205).

그러나. 상기한 종래 기술에서는 세탁수 가열이 완료된 직후에 바로 순환펌프를 구동시켜 세탁수를 순환시키고 있는데, 세탁수 가열 직후 바로 세탁수를 순환시키면 열손실이 크게 발생된다.But. In the above-described prior art, the washing water is circulated by driving the circulation pump immediately after the washing water heating is completed. If the washing water is circulated immediately after the washing water heating, a large heat loss is generated.

본 발명은 상기한 바와 같은 문제점들을 해결하기 위하여 안출한 것으로 히팅 완료후 열에너지 보존 지속성을 향상시킬 수 있는 드럼세탁기의 제어방법을 제공하는데 그 목적이 있다.An object of the present invention is to provide a control method of a drum washing machine that can improve the persistence of thermal energy storage after heating is completed.

본 발명에 따른 드럼세탁기의 제어방법은 세탁수 가열을 완료한 후에 순환펌프를 일정시간 동안에 정지시키는 것을 특징으로 한다.The control method of the drum washing machine according to the present invention is characterized in that the circulating pump is stopped for a predetermined time after the washing water is heated.

또한, 본 발명에 따른 드럼세탁기의 제어 방법은 세탁수 가열을 완료했는지 여부를 판단하는 제 1 단계와, 세탁수 가열이 완료되었으면 해당 시점부터 일정시간이 경과되었는지 여부를 판단하는 제 2 단계와, 상기 제 2 단계에서 일정시간이 경과되지 않은 것으로 판단되면 순환펌프를 정지시키고 일정시간이 경과된 것으로 판단되면 순환펌프를 구동시키는 제 3 단계를 포함하여 이루어짐을 특징으로 한다.In addition, the control method of the drum washing machine according to the present invention includes a first step of determining whether the washing water heating is completed, and a second step of determining whether or not a predetermined time has elapsed from the corresponding time when the washing water heating is completed; And a third step of stopping the circulation pump if it is determined that the predetermined time has not elapsed in the second step and driving the circulation pump if it is determined that the predetermined time has elapsed.

바람직하게, 상기 제 1 단계는 세탁수가 기설정 온도에 도달하였는지 여부를 판단하는 단계인 것을 특징으로 한다.Preferably, the first step is a step of determining whether the wash water has reached a predetermined temperature.

본 발명의 다른 목적, 특징 및 이점들은 첨부한 도면을 참조한 실시예들의 상세한 설명을 통해 명백해 질 것이다.Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 3은 본 발명에 따른 드럼세탁기의 세탁 과정을 나타낸 순서도이다.3 is a flowchart illustrating a washing process of the drum washing machine according to the present invention.

사용자가 세탁을 하기 위하여 도어(64)를 열고 세탁포를 드럼(54) 내부에 투입하고 도어(64)를 닫은 후에 드럼세탁기를 동작시키면 외부로부터 세탁수가 공급되게 된다.When the user opens the door 64 to wash the laundry, inserts the laundry cloth into the drum 54, closes the door 64, and operates the drum washing machine to supply the washing water from the outside.

이후 급수가 완료되면(S301), 모터(55)와 순환펌프(60)가 구동되어 드럼(54)내의 세탁포에 세탁수가 고르게 적셔지게 된다(S302).After the water supply is completed (S301), the motor 55 and the circulation pump 60 is driven so that the washing water is evenly soaked in the laundry cloth in the drum 54 (S302).

즉, 상기 모터(55) 구동에 의해 드럼(54)이 회전되고, 상기 터브(53)의 저면으로 흐르는 세탁수는 순환배관(61)을 통해 순환펌프(60)로 유입되고 순환펌프(60)에 의해 다시 터브(53) 상면으로 강제 순환되어 드럼(54) 내에 뿌려지면서 세탁포에 세탁수가 고르게 적셔지게 된다. That is, the drum 54 is rotated by the driving of the motor 55, and the wash water flowing to the bottom surface of the tub 53 flows into the circulation pump 60 through the circulation pipe 61 and the circulation pump 60. By the forced force circulated back to the upper surface of the tub 53 is sprayed in the drum 54, the washing water is evenly soaked in the laundry cloth.

그 다음 세탁수를 가열하는 히팅(heating) 동작을 실시한다(S303).Then, a heating operation for heating the washing water is performed (S303).

그리고, 세탁수가 설정 온도에 도달하였는지를 실시간으로 감지하여 히팅 동작 완료 여부를 판단한다(S304). Then, it is determined whether the washing water reaches the set temperature in real time to determine whether the heating operation is completed (S304).

세탁수가 설정 온도에 도달하지 못하였으면 히팅 동작이 완료되지 않은 것으로 판단하고 상기 스텝 303(S303)으로 리턴하여 세탁수를 계속해서 가열한다. If the wash water does not reach the set temperature, it is determined that the heating operation is not completed, the flow returns to step 303 (S303) and continues to heat the wash water.

반면, 세탁수가 설정 온도에 도달하였으면 히팅 동작이 완료된 것으로 판단한다. On the other hand, when the wash water reaches the set temperature, it is determined that the heating operation is completed.

이어, 열손실을 줄이기 위하여 순환펌프(60)를 구동시키지 않고 일정시간동안 대기한다.Subsequently, in order to reduce heat loss, the circulation pump 60 is not driven and waits for a predetermined time.

즉, 히팅 동작이 완료되면 히팅 동작 완료 시점부터 일정시간이 경과되었는지 여부를 판단한다(S305).That is, when the heating operation is completed, it is determined whether a predetermined time has elapsed from the completion of the heating operation (S305).

상기 판단 결과, 아직 해당 시간이 경과되지 않은 경우에는 순환펌프를 오프(off)시키고(S306) 상기 스텝 305(S305)로 리턴한다.As a result of the determination, if the time has not yet elapsed, the circulation pump is turned off (S306) and the flow returns to the step 305 (S305).

반면, 해당 시간이 경과되었으면 순환펌프 및 모터를 구동시켜 본격적인 세탁을 진행한다(S307).On the other hand, if the corresponding time has elapsed, the circulation pump and the motor are driven to perform full washing (S307).

상기와 같은 본 발명의 드럼세탁기의 제어방법은 세탁수 가열을 완료한 후 일정시간동안 순환펌프를 구동하지 않아 일정시간 동안 고온 상태가 유지시키므로 열 보존성이 향상되는 효과가 있다.The control method of the drum washing machine of the present invention as described above does not drive the circulation pump for a predetermined time after the washing water heating is completed, thereby maintaining a high temperature for a certain time, thereby improving heat preservation.

이상 설명한 내용을 통해 당업자라면 본 발명의 기술 사상을 이탈하지 아니하는 범위에서 다양한 변경 및 수정이 가능함을 알 수 있을 것이다.Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

따라서, 본 발명의 기술적 범위는 실시예에 기재된 내용으로 한정하는 것이 아니라 특허 청구범위에 의해서 정해져야 한다.Therefore, the technical scope of the present invention should not be limited to the contents described in the examples, but should be defined by the claims.
