본 발명은 드럼세탁기에 관한 것으로 특히, 세탁수를 가열하는 히팅 구간동안에 열에너지 손실을 줄여 히팅(heating) 효율을 향상시키기에 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 improving heating efficiency by reducing heat energy loss during a heating section for heating washing water.

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

이때, 상기 순환펌프(60)는 멈추지 않고 계속 구동되는데 이로 인해 히팅 동작 동안에도 세탁수는 순환배관(61)을 타고 강제 순환되게 된다.At this time, the circulating pump 60 continues to be driven without stopping, thereby washing water is forced to circulate through the circulation pipe 61 even during the heating operation.

따라서, 가열된 세탁수는 순환배관(61)을 타고 순환하는 동안에 외부에 열을 빼앗겨 식어버리게 되므로 히팅 효율이 낮다.Therefore, the heated wash water is deprived of heat to the outside while circulating in the circulation pipe 61, so the heating efficiency is low.

또한, 순환하는 동안에 세탁수가 식어버리므로 세탁수를 설정 온도까지 가열하는데 많은 시간이 소요되어 세탁시간이 지연되게 된다.In addition, since the washing water cools down during the circulation, it takes much time to heat the washing water to the set temperature, which delays the washing time.

본 발명은 상기한 바와 같은 문제점들을 해결하기 위하여 안출한 것으로 세탁수를 가열하는 동안 에너지 손실을 줄여 히팅 효율을 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 heating efficiency by reducing energy loss while heating wash water.

본 발명의 다른 목적은 세탁시간을 단축시키는데 있다.Another object of the present invention is to shorten the washing time.

본 발명에 따른 드럼세탁기의 제어방법은 세탁수를 가열하는 동안에 순환 펌프를 정지시키는 것을 특징으로 한다.The control method of the drum washing machine according to the present invention is characterized in that the circulation pump is stopped while heating the washing water.

또한, 본 발명에 따른 드럼세탁기의 제어방법은 세탁수 가열 구간에 진입했는지 여부를 판단하는 제 1 단계와, 상기 제 1 단계의 판단 결과 세탁수 가열 구간에 진입한 것으로 확인되면 순환펌프를 정지시키는 제 2 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 section has been entered, and when it is determined that the washing water heating section has been entered as a result of the determination of the first step, stopping the circulation pump. It comprises a second step.

바람직하게, 상기 제 1 단계의 판단 결과 세탁수 가열 구간에 진입하지 않은 것으로 확인되면 현재 세탁기가 진입해있는 해당 행정의 제어에 따라서 순환펌프를 구동시키는 것을 특징으로 한다.Preferably, if it is determined that the washing water is not entered into the washing water heating section as a result of the determination of the first step, the circulation pump may be driven according to the control of the corresponding stroke in which the washing machine is currently entering.

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 실시해야 하는데 히팅시 순환펌프(60) 구동에 따른 열에너지 손실을 막기 위하여 히팅 구간 동안 순환펌프(60)가 구동되지 않도록 제어해야 한다.Then, a heating operation for heating the washing water should be performed. In order to prevent heat energy loss due to driving the circulation pump 60 during heating, the circulation pump 60 should be controlled so as not to be driven during the heating section.

이를 위해 세탁기가 히팅 구간에 진입했는지 여부를 실시간으로 판단한다(S303).To this end, it is determined in real time whether the washing machine has entered the heating section (S303).

상기 판단 결과, 히팅 구간에 진입한 것으로 확인되면 순환펌프를 정지시키고(S304), 히터(63)에 전원을 인가하여 설정 온도까지 세탁수를 가열하는 히팅 동작을 실시한다. As a result of the determination, if it is determined that the heating section has been entered, the circulation pump is stopped (S304), and the heating operation is performed by heating power to the set temperature by applying power to the heater 63.

반면, 세탁기가 히팅 구간에 있지 않은 것으로 확인되면 현재 세탁기가 진입해 있는 해당 행정의 제어에 따라 순환펌프(60)를 구동시킨다(S305).On the other hand, if it is determined that the washing machine is not in the heating section, the circulation pump 60 is driven under the control of the corresponding stroke in which the washing machine is currently entering (S305).

이후, 세탁수가 설정 온도까지 도달하게 되면 히팅 동작을 종료하고 본격적인 세탁을 실시한다.After that, when the washing water reaches the set temperature, the heating operation is terminated and washing is performed in earnest.

상기와 같은 본 발명의 드럼세탁기의 제어방법은 다음과 같은 효과가 있다.The control method of the drum washing machine of the present invention as described above has the following effects.

세탁수를 가열하는 동안 순환펌프가 구동되지 않기 때문에 세탁수가 순환하지 않으므로 세탁수 순환에 따른 열 에너지 손실을 막을 수 있어 히팅 효율을 향상시킬 수 있다.Since the circulation pump is not driven while the washing water is heated, the washing water does not circulate, thereby preventing heat energy loss due to the washing water circulation, thereby improving heating efficiency.

또한, 열 에너지 손실이 줄어들기 때문에 세탁수를 설정 온도까지 가열하는 히팅 동작시간이 줄어 전체적인 세탁시간을 단축시킬 수 있다.In addition, since the heat energy loss is reduced, the heating operation time for heating the wash water to the set temperature is reduced, thereby reducing the overall washing time.

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.
