드럼 세탁기 건조행정 방법{Drying method of drum type washing machine}Drying method of drum type washing machine

도 1 은 종래의 건조행정을 나타낸 순서도. 1 is a flow chart showing a conventional drying operation.

도 2 는 본 발명에 따른 드럼 세탁기 건조행정 방법을 나타낸 순서도.2 is a flow chart showing a drum washing machine drying administration method according to the present invention.

본 발명은 세탁기에 관한 것으로서, 더욱 상세하게는 세탁물의 양과 특징에 따라 건조시간을 조정한 세탁기 건조행정 방법에 관한 것이다. The present invention relates to a washing machine, and more particularly, to a washing machine drying administrative method adjusting the drying time according to the amount and characteristics of the laundry.

일반적으로, 세탁기는 기설정된 알고리즘에 따라 세탁, 헹굼 및 탈수행정을 수행하여 세탁물을 세탁하는 기계장치로, 세탁방식에 따라 펄세이터방식, 교반식, 드럼식 등으로 구분된다. In general, a washing machine is a machine for washing laundry by performing washing, rinsing, and dehydrating strokes according to a predetermined algorithm. The washing machine is classified into a pulsator type, a stirring type, a drum type, and the like according to a washing method.

특히, 드럼 세탁기는 다른 종류의 세탁기에 비해 세탁물 손상률이 가장 작고, 사용수량이 최저라는 장점을 구비하여 널리 사용되고 있으며, 다기능 및 완전자동화를 요구하는 사용자의 욕구를 충족시키고 홈오토메이션화되어 가는 기술발달추이에 발맞추기 위하여 각종 부가기능들이 추가되고 있다. In particular, drum washing machines are widely used because they have the lowest laundry damage rate and the lowest amount of water used compared to other types of washing machines. In order to keep up with the development trend, various additional functions are added.

그리고, 상기한 부가기능 중 하나로서 기본세탁행정 즉, 세탁, 헹굼, 탈수 이외에 건조행정이 널리 채용되고 있으며, 젖은 상태의 의류 등을 세탁행정을 수행하지 않고 단지 건조시키기 위한 건조전용코스가 건조행정의 일부로서 채용되기도 하였다. In addition, as one of the above-described additional functions, a drying cycle is widely adopted in addition to the basic washing cycle, that is, washing, rinsing, and dehydration, and a drying-only course for drying only wet clothes and the like without performing the washing stroke is a drying stroke. It was also adopted as part of the.

종래의 드럼 세탁기의 세탁물 건조방법을 간단히 설명하면, 사용자가 드럼 세탁기의 드럼 내부에 세탁물을 넣은 다음 건조행정을 포함 세탁명령, 건조전용코스 수행명령 또는 건조행정을 제외한 세탁명령을 입력하며, 드럼 세탁기의 제어부는 세탁명령이 입력되는지 여부를 판단하여 세탁명령이 입력되면 세탁명령 중에 건 조행정이 선택되었는 지 여부를 판단하고, 판단결과 건조행정이 선택되지 않은 세탁명령일 경우 세탁포의 포량을 감지하고 적절히 급수 또는 배수를 반복해가며 입력된 세탁명령에 상응하도록 세탁, 헹굼 또는 탈수를 수행한다. The laundry drying method of the conventional drum washing machine will be described briefly. The user puts laundry into the drum of the drum washing machine, and then inputs a washing instruction including a drying administration, a washing instruction for performing a drying course, or a washing instruction except for the drying administration. The controller determines whether a washing instruction is input, and when a washing instruction is input, determines whether a drying stroke is selected during the washing instruction. Then repeat the water supply or drainage as appropriate, and wash, rinse or dehydrate to match the washing instructions.

한편, 상기 판단결과 건조행정이 선택된 경우 건조전용코스가 선택되었는지 판단하여 건조전용코스가 선택된 경우 건조행정을 수행하고, 건조전용코스가 아닌 경우 입력된 세탁명령에 상응하도록 세탁, 헹굼 또는 탈수를 수행한 다음 건조행정을 수행한다. On the other hand, if the drying administration is selected, it is determined whether the drying only course is selected, and if the drying only course is selected, the drying administration is performed, and if the drying only course is not performed, the washing, rinsing, or dehydration is performed to correspond to the input washing instruction. And then carry out a drying stroke.

이 때 건조행정은 드럼 세탁기 내부에 있는 히터를 이용한 열풍을 드럼 내부를 경유하도록 순환시켜 세탁포를 건조시킨다. At this time, the drying administration circulates the hot air using the heater in the drum washing machine to pass through the drum to dry the laundry cloth.

특히, 건조행정은 도 1 에 도시된 바와 같이, 건조행정이 시작(S10)되면, 건조히터가 온(S20)되고, 이 건조히터는 기 설정된 시간 동안 구동(S30)한 후 건조행정이 종료(S40)하게 되는데, 이는 세탁물의 양과 특징을 전혀 고려하지 않은 것으로서, 세탁물이 많거나 세탁수의 흡수가 많은 세탁물인 경우 충분히 건조되지 않을 수도 있었다. In particular, as shown in FIG. 1, when the drying stroke starts (S10), the drying heater is turned on (S20), and the drying heater is driven for a predetermined time (S30), and then the drying stroke ends ( S40), which does not consider the amount and characteristics of the laundry at all, if the laundry is a lot of laundry or wash water absorbs a lot of water could not be sufficiently dried.

즉, 세탁물의 양과 특징을 고려한 세탁물 건조가 이루어지지 않는다는 문제점이 있었다.That is, there was a problem that laundry drying is not made in consideration of the quantity and characteristics of the laundry.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 탈수행정 완료후, 세탁물의 양과 특징에 따른 로드 센싱값을 측정하고 상기 로드 센싱값에 따른 건조시간을 재설정하여 재설정된 건조시간에 따라 건조행정을 수행하도록 한 세탁기 건조행정 방법을 제공하는데 그 목적이 있다. The present invention has been made to solve the above-described problems, after completion of the dehydration administration, the load sensing value according to the amount and characteristics of the laundry is measured and the drying administration according to the reset drying time by resetting the drying time according to the load sensing value The purpose is to provide a washing machine drying administration method to perform the.

전술한 목적을 달성하기 위해 안출된 본 발명의 구성은 다음과 같다. 본 발명은 사용자의 세탁명령에 따라 초기에 세탁물의 로드를 센싱하여 초기 로드 센싱값에 따라 세탁, 헹굼, 탈수행정을 수행한 후, 건조행정을 수행하는 드럼 세탁기의 건조행정방법에 있어서, 건조행정이 시작되면, 드럼 내부의 세탁물에 대한 현재 로드 센싱값을 측정하여 세탁행정시 측정된 초기 로드 센싱값과 비교하는 제1단계, 현재 로드 센싱값이 초기 로드 센싱값의 설정 범위내에 포함되는 지를 판단하는 제2단계, 현재 로드 센싱값이 초기 로드 센싱값의 설정 범위내에 포함되지 않으면, 새로운 건조시간을 재설정하는 제3단계, 및 재설정된 새로운 건조시간에 따라 히터를 온시켜 건조행정을 수행하는 제4단계를 포함하여 이루어지는 것을 특징으로 한다.The configuration of the present invention devised to achieve the above object is as follows. According to the present invention, in the drying administrative method of a drum washing machine performing a drying operation after washing, rinsing, and dehydrating the washing load according to an initial load sensing value by initially sensing the load of the laundry according to a washing instruction of the user. In this case, the first step of measuring the current load sensing value for the laundry in the drum and comparing it with the initial load sensing value measured at the laundry administration, and determining whether the current load sensing value is within the setting range of the initial load sensing value. In a second step of the present invention, if the current load sensing value is not within the set range of the initial load sensing value, the third step of resetting the new drying time, and the step of turning on the heater according to the reset new drying time to perform the drying administration Characterized in that it comprises four steps.

여기서, 제3단계는 현재 로드 센싱값이 설정 범위를 벗어난 크기에 비례하여 새로운 건조시간이 설정되는 것을 특징으로 하는 한다.Here, the third step is characterized in that the new drying time is set in proportion to the size of the current load sensing value outside the set range.

또한, 제3단계는 현재 로드 센싱값이 초기 로드 센싱값의 설정 범위내에 포함되면 기 설정된 건조시간에 따라 건조행정을 수행하는 것을 특징으로 한다.In addition, the third step is characterized in that if the current load sensing value is included in the setting range of the initial load sensing value, the drying operation is performed according to the preset drying time.

이하에서는 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 2 는 본 발명에 따른 드럼 세탁기 건조행정 방법의 순서도이다. 2 is a flow chart of a drum washing machine drying administration method according to the present invention.

본 발명에 따른 건조행정 방법은 세탁행정, 헹굼행정, 및 탈수행정이 완료된 후, 건조행정이 시작(S110)되면, 드럼 내부의 있는 세탁물의 로드를 센싱(S120)한다. In the drying administration method according to the present invention, after the washing stroke, the rinsing stroke, and the dehydration stroke are completed, when the drying stroke is started (S110), the load of the laundry in the drum is sensed (S120).

이는 탈수행정 완료 후, 세탁물에 흡수되어 있는 세탁수의 양을 측정하기 위한 것으로서, 세탁물은 그 재료나 특징 등에 따라 세탁수가 흡수되는 양이 서로 상이하기 때문이다. This is for measuring the amount of wash water absorbed in the laundry after the completion of the dehydration operation, because the laundry is different from each other in the amount of wash water absorbed according to the material and characteristics.

이와 같이, 세탁물의 로드를 센싱하면, 측정된 현재 로드 센싱값과 초기 로드 센싱값과 비교(S130)하여 기 설정된 초기 로드 센싱값의 설정 범위에 현재 로드 센싱값이 포함되어 있는 지를 판단(S140)한다. As described above, when the load of the laundry is sensed, the measured current load sensing value and the initial load sensing value are compared (S130), and it is determined whether the current load sensing value is included in the set range of the preset initial load sensing value (S140). do.

이 때, 현재 로드 센싱값이 초기 로드 센싱값의 설정 범위 이내에 포함되어 있으면, 건조히터를 온(S150)시켜 세탁물의 건조를 시작하고, 기 설정된 건조시간이 경과하는 지를 계속적으로 판단(S160)한다. At this time, if the current load sensing value is within the setting range of the initial load sensing value, the drying heater is turned on (S150) to start drying the laundry, and it is continuously determined whether the preset drying time has elapsed (S160). .

건조히터를 온시킨 후, 설정된 건조시간이 경과하면, 건조행정을 종료(S200)하고 모든 세탁과정을 종료한다. After turning on the drying heater, when the set drying time has elapsed, the drying administration is terminated (S200) and all washing processes are finished.

한편, 현재 로드 센싱값이 초기 로드 센싱값의 범위 내에 포함되어 있지 않으면, 새로운 건조시간을 재설정(S170)한다. On the other hand, if the current load sensing value is not included in the range of the initial load sensing value, the new drying time is reset (S170).

이는 탈수행정완료 후, 세탁물에 포함되어 있는 세탁수의 양과 특징을 고려하여 건조시간을 새로이 설정하는 것으로서, 상기한 설정범위를 벗어난 크기에 비 례하여 다양한 건조시간이 적용될 수 있다. 예를 들어, 현재 로드 센싱값이 설정범위를 작게 벗어나면 건조히터의 구동시간 즉, 건조시간이 작게 설정되고, 설정범위를 크게 벗어나면 건조시간이 크게 설정된다. This is to set a new drying time in consideration of the amount and characteristics of the wash water included in the laundry after the completion of the dehydration administration, a variety of drying time can be applied in proportion to the size outside the above-mentioned setting range. For example, when the current load sensing value is out of the setting range, the driving time of the drying heater, that is, the drying time is set small, and when the current load sensing value is out of the setting range, the drying time is set large.

따라서, 탈수행정완료 후, 세탁물의 양과 크기에 따라서 건조시간을 새로이 설정함으로써 효과적인 건조가 이루어지도록 한다. Therefore, after completion of the dehydration administration, the drying time is newly set according to the amount and size of the laundry so that effective drying is achieved.

이와 같이, 설정범위에 따른 건조시간이 재설정되면, 건조히터를 온(S180)시키고, 상기 재설정된 건조시간이 경과하는 지를 계속적으로 판단(S180)한다.As such, when the drying time according to the set range is reset, the drying heater is turned on (S180), and it is continuously determined whether the reset drying time has elapsed (S180).

이 때, 재설정된 건조시간이 경과하면 건조행정을 종료(S200)하고, 모든 세탁행정을 종료한다. At this time, when the reset drying time has elapsed, the drying administration is terminated (S200), and all washing administrations are finished.

즉, 본 발명에 따른 드럼 세탁기 건조행정방법은 탈수행정 완료 후, 세탁물의 로드를 센싱하여 센싱된 센싱값이 기 설정된 초기 로드 센싱값의 설정 범위에 포함되어 있는 지를 판단하고, 초기 로드 센싱값의 범위를 벗어나는 경우 그 크기에 따라 건조시간을 새로이 설정하여 새로이 설정된 건조시간에 따라 건조행정을 수행함으로써, 세탁물 건조의 효율성과 효과를 높일 수 있도록 한다. That is, in the drum washing machine drying administration method according to the present invention, after the completion of the dehydration stroke, the load of the laundry is sensed to determine whether the sensed sensing value is included in a preset initial load sensing value, If it is out of the range by setting a new drying time according to the size to perform the drying administration according to the newly set drying time, to improve the efficiency and effectiveness of laundry drying.

본 발명은 전술한 실시예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수 있다. The present invention is not limited to the above-described embodiments and can be carried out in various modifications within the scope of the technical idea of the present invention.

이와 같이 구성되는 본 발명에 따르면, 탈수행정 완료후, 세탁물의 양과 특징에 따른 로드 센싱값을 측정하고 상기 로드 센싱값에 따른 건조시간을 재설정하 여 재설정된 건조시간에 따라 건조행정을 수행하도록 함으로써, 효과적인 건조행정이 이루어질 수 있고, 건조 기능을 더욱 향상시킬 수 있다. According to the present invention constituted as described above, after completion of the dehydration stroke, by measuring the load sensing value according to the amount and characteristics of the laundry and by resetting the drying time according to the load sensing value to perform the drying administration according to the reset drying time Effective drying administration can be achieved, and the drying function can be further improved.
