본 발명은 드럼세탁기에 관한 것으로서, 더욱 상세하게는 세탁행정 중에 세탁수를 유동시킴으로써 벨로우즈 호스에 고인 세제가 세탁물을 세탁하는데 사용될수 있도록 하여 보다 작은 양의 세제를 사용하도록 하는 드럼세탁기의 세탁수 펌핑 장치 및 이에 따른 세탁 제어 방법에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to pumping the washing water of a drum washing machine, by using a smaller amount of detergent so that the detergent accumulated in the bellows hose can be used to wash the laundry by flowing the washing water during the washing stroke. The present invention relates to an apparatus and a laundry control method.

일반적으로 세탁기는 기설정된 알고리즘에 따라 세탁행정, 헹굼행정 및 탈수행정을 수행하여 세탁물을 세탁하는 기계장치로서, 세탁방식에 따라 펄세이터식, 교반식, 드럼식 등으로 구분된다.In general, a washing machine is a machine for washing laundry by performing a washing stroke, a rinsing stroke, and a dehydrating stroke 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.

상기 드럼식 세탁방식을 사용하는 드럼세탁기는 다른 종류의 세탁기에 비해 세탁물 손상률 최소 및 사용세탁수량 최저라는 장점을 구비하여 널리 사용되고 있다.Drum washing machine using the drum type washing method is widely used with the advantages of the minimum laundry damage rate and the lowest amount of laundry used compared to other types of washing machines.

이하, 종래의 드럼세탁기에 관해 참조도면 도 1 및 도 2를 참조하여 설명하면 다음과 같다.Hereinafter, a conventional drum washing machine will be described with reference to FIGS. 1 and 2.

도 1은 종래 드럼세탁기의 펌프 하우징의 위치 및 연결상태를 나타낸 개략도이고, 도 2는 도 1의 드럼세탁기의 세탁수 펌핑 장치 및 세탁수의 유동방향을 나타낸 개략도이다.1 is a schematic view showing the position and connection of the pump housing of the conventional drum washing machine, Figure 2 is a schematic diagram showing the flow direction of the washing water pumping device and the washing water of the drum washing machine of FIG.

도 1 및 도 2를 참조하면, 종래 드럼세탁기는 크게 본체(미도시)와, 상기 본체의 상부에 설치되어 사용자가 세탁기능 및 세탁시간 등을 입력시키는 컨트롤 패널(미도시)과, 상기 본체 내부에 댐퍼에 의해 고정된 터브(1)(tub)와, 상기 터브(1)내에 설치되어 세탁물이 투입되는 드럼(2)과, 상기 드럼(2)에 밸트를 통해 구동력을 전달하여 드럼(2)을 회전시키면서 세탁관련행정을 수행하는 모터로 이루어진다.1 and 2, a conventional drum washing machine is largely installed on a main body (not shown), a control panel (not shown) installed at an upper portion of the main body, and a user inputs a washing function and a washing time, and the inside of the main body. A tub (1) fixed by a damper to the drum, a drum (2) installed in the tub (1), into which laundry is put, and a driving force transmitted to the drum (2) through a belt (2) Rotation is made of a motor that performs the washing-related stroke.

또한, 세제를 투입하기 위한 세제통(미도시)과, 상기 세제통과 연결되어 세탁수 또는 상기 세제통의 세제가 혼합된 세탁수를 급수하기 위한 급수호스(미도시)와, 세탁행정에서 사용된 세탁수를 터브(1)에서 배출하기 위한 벨로우즈 호스(11)와, 상기 벨로우즈 호스(11)에 연결되어 세탁수를 강제로 펌핑하기 위한 펌프(13) 및 펌프 하우징(12)을 포함하여 구성된다.In addition, a detergent container for injecting detergent (not shown), a water hose (not shown) connected to the detergent container for supplying the wash water or the wash water in which the detergent of the detergent container is mixed, and the wash water used in the washing administration It is configured to include a bellows hose 11 for discharging from the tub 1, and a pump 13 and a pump housing 12 connected to the bellows hose 11 for forcibly pumping the wash water.

이와 같이 구성된 드럼세탁기의 동작을 살펴보면, 사용자가 본체 전면에 부착된 도어를 열고 세탁물을 투입한 다음 컨트롤 패널(미도시)의 버튼을 누름으로써 세탁명령을 입력하면, 급수밸브(미도시)가 열리면서 세탁에 사용되는 물이 세제통을 통해 터브(1) 내로 유입됨으로써 세탁수와 세제가 드럼(2) 내에 투입된다.Looking at the operation of the drum washing machine configured as described above, when the user opens the door attached to the front of the main body, puts laundry and inputs a washing command by pressing a button on the control panel (not shown), the water supply valve (not shown) opens. The water used for washing is introduced into the tub 1 through the detergent container so that the washing water and the detergent are introduced into the drum 2.

이때, 사용자가 컨트롤 패널에서 삶은 세탁기능을 선택했다면 급수되는 물이 설정된 온도까지 데워져 세탁물을 삶게 된다.At this time, if the user selects the boiled washing function in the control panel, the water to be heated is heated to a set temperature to boil the laundry.

이와 같은 드럼세탁기에서 세탁수가 터브(1)와 드럼(2)에 일정높이 만큼 채워지면 세탁수의 급수는 중단되고 상기 모터가 일정주기를 갖고 회전하게 된다.In such a drum washing machine, when the washing water is filled in the tub 1 and the drum 2 by a predetermined height, the water supply of the washing water is stopped and the motor rotates with a certain period.

이에 따라, 드럼(2)의 회전에 따라 세탁물이 유동되어 상기 세탁물이 세탁수와의 마찰력과 세제의 분해력 등에 의해 세탁된다.Accordingly, the laundry flows as the drum 2 rotates, and the laundry is washed by the frictional force with the wash water and the decomposition force of the detergent.

이러한 세탁행정이 완료되면, 상기 펌프 하우징(12)에 연결된 펌프를 가동하여 펌프 하우징(12) 내에 소정의 압력을 발생시킴으로써 터브(1)에 연결된 벨로우즈 호스(11)를 통해 펌프 하우징에 배출된 세탁수를 도 2의 화살표 방향과 같이 배수호스(14)를 통해 외부로 배출되도록 한다.When the washing stroke is completed, the laundry discharged to the pump housing through the bellows hose 11 connected to the tub 1 by operating the pump connected to the pump housing 12 to generate a predetermined pressure in the pump housing 12. The water is discharged to the outside through the drain hose 14 as shown by the arrow in FIG.

이어, 상기 세탁수가 배수호스(14)를 통해 배출된 후에는 다시 급수호스를 통해 터브(1) 내에 깨끗한 물이 공급되어 헹굼행정이 시작되며, 상기 헹굼행정은세탁행정시와 동일한 작용에 의해 완료된다.Subsequently, after the wash water is discharged through the drain hose 14, clean water is supplied to the tub 1 through the water supply hose again, and a rinsing stroke is started. The rinsing stroke is completed by the same action as the washing stroke. do.

상기한 헹굼행정이 사용자가 컨트롤 패널에서 설정한 횟수만큼 반복된 후에는 세탁수가 배수호스(14)를 통해 외부로 배출되고, 이어 세탁물에 함유된 수분을 원심력에 의해 빠져 나오게 하는 탈수행정이 시작된다.After the rinsing cycle is repeated the number of times set by the user in the control panel, the washing water is discharged to the outside through the drain hose 14, and then a dehydration stroke is started to drain the water contained in the laundry by centrifugal force. .

이상에서와 같이, 상기 드럼세탁기는 세탁행정, 헹굼행정 및 탈수행정을 순차적으로 수행하면서 세탁물의 세탁을 완료한다.As described above, the drum washing machine completes the washing of the laundry while sequentially performing the washing stroke, the rinsing stroke and the dehydrating stroke.

그러나, 드럼세탁기의 세탁행정이 시작되는 때에 터브(1) 내에 물과 세제가 투입되면 터브 내에서 물과 세제가 혼합되는데, 이때 터브(1)의 하면에 일단이 연결된 벨로우즈 호스(11)에 소량의 세제가 유입되어 고이게 된다.However, if water and detergent are introduced into the tub 1 at the start of the washing operation of the drum washing machine, water and detergent are mixed in the tub. At this time, a small amount of the bellows hose 11 connected to the bottom of the tub 1 is connected. Of detergent is introduced and it is collected.

이때, 상기 벨로우즈 호스(11)에 고여있는 세제는 드럼(2)이 회전되면서 세탁작용을 하더라도 세탁물의 세탁에 아무런 도움을 주지 못하므로, 결과적으로 세제를 낭비하게 되므로 세탁효율에 영향을 주지 못한다.In this case, the detergent accumulated in the bellows hose 11 does not help washing the laundry even when the drum 2 is rotated, and thus does not affect the washing efficiency because the detergent is wasted.

또한, 세탁행정이 완료된 후에 상기 터브(1)에 수용된 세탁수가 벨로우즈 호스(11), 펌프 하우징(12) 및 배수호스(14)를 통해 외부로 배출되는 동안에 상기 벨로우즈 호스(11)에 고여있던 세제도 세탁수에 혼합되어 외부로 배출된다.In addition, the detergent accumulated in the bellows hose 11 while the washing water received in the tub 1 is discharged to the outside through the bellows hose 11, the pump housing 12, and the drain hose 14 after the washing stroke is completed. Also mixed in the wash water is discharged to the outside.

이에 따라, 세탁물을 세탁할 때에 보다 많은 양의 세제를 사용해야 하므로 수질오염을 보다 가중시킬 수 있는 문제점이 있다.Accordingly, when washing laundry, a larger amount of detergent must be used, which may increase water pollution.

상기한 제반 문제점을 해결하기 위해, 본 발명은 세탁행정 중에 세탁수를 유동시킴으로써 벨로우즈 호스에 고인 세제가 세탁물을 세탁하는데 사용될 수 있도록하여 보다 작은 양의 세제를 사용하도록 하는 것을 그 목적으로 한다.In order to solve the above problems, an object of the present invention is to use a smaller amount of detergent so that the detergent accumulated in the bellows hose can be used to wash the laundry by flowing the wash water during the washing stroke.

또한, 상기한 목적을 달성하기 위한 본 발명의 다른 형태에 따르면, 세탁행정시에 펌프 하우징의 일측에 설치된 순환펌프를 작동시켜 터브로부터 펌프 하우징에 토출된 세탁수를 순환호스를 통해 터브에 다시 공급시키는 순환단계를 더 포함하는 드럼세탁기의 세탁 제어 방법을 제공한다.In addition, according to another aspect of the present invention for achieving the above object, by operating the circulating pump installed on one side of the pump housing during the laundry administration, the washing water discharged from the tub to the pump housing back to the tub through the circulation hose It provides a laundry control method of the drum washing machine further comprising a circulation step of supplying.

본 발명에 따른 드럼세탁기는 종래의 드럼세탁기와 거의 동일하므로 동일한 부분에 대해서는 동일한 도번을 부여하고 동일한 구조 및 작용에 대해서는 그 설명을 생략하기로 한다.Since the drum washing machine according to the present invention is almost the same as the conventional drum washing machine, the same parts will be given the same number and the description of the same structure and operation will be omitted.

이하, 본 발명에 따른 드럼세탁기의 세탁수 펌핑 장치 및 이에 따른 세탁 제어 방법에 대해 참조도면 도 3을 참조하여 설명하면 다음과 같다.Hereinafter, referring to FIG. 3, a washing water pumping apparatus and a washing control method according to the present invention are described below with reference to FIG. 3.

도 3은 본 발명에 따른 드럼세탁기의 세탁수 펌핑 장치 및 세탁수의 유동방향을 나타낸 개략도이다.Figure 3 is a schematic diagram showing the flow direction of the washing water pumping device and the washing water of the drum washing machine according to the present invention.

도 3을 참조하면, 상기 드럼세탁기의 세탁수 펌핑 장치는 세탁수를 수용하는 터브(1)에 연결된 벨로우즈 호스(11)에 그 일단부가 연결된 펌프 하우징(22)과, 상기 펌프 하우징(22)의 일측에 연결된 순환펌프(24)와, 상기 순환펌프(24)에 일단부가 연결되고 그 타단부가 터브(1)에 연결된 순환호스(24a)와, 상기 펌프 하우징(22)의 타측에 연결된 배수펌프(23)와, 상기 배수펌프(23)에 일단부가 연결되는 배수호스(23a)로 이루어진다.Referring to FIG. 3, the drum washing machine pumping device includes a pump housing 22 having one end connected to a bellows hose 11 connected to a tub 1 for receiving wash water, and a pump housing 22 of the pump housing 22. A circulation pump 24 connected to one side, a circulation hose 24a having one end connected to the circulation pump 24 and the other end connected to the tub 1, and a drain pump connected to the other side of the pump housing 22 23 and a drain hose 23a having one end connected to the drain pump 23.

이러한 구조를 갖는 드럼세탁기에 있어서, 사용자가 드럼(2)에 세탁물을 투입한 다음 컨트롤 패널의 버튼을 누름으로써 세탁명령을 입력하면, 급수밸브(미도시)가 열리면서 세탁에 사용되는 물이 세제통을 통해 터브(1) 내로 유입된다.In the drum washing machine having such a structure, when a user inputs laundry to the drum 2 and then inputs a washing command by pressing a button on the control panel, a water supply valve (not shown) opens and the water used for washing removes the detergent container. It is introduced into the tub (1) through.

이에 따라, 세탁수와 섬유 유연제와 같은 각종 세제가 드럼(2) 내에 투입된다.Accordingly, various detergents such as washing water and fabric softener are introduced into the drum 2.

상기 드럼(2) 내에 투입된 세제는 세탁수와 혼합되기도 하지만, 터브(1)의 하면에 고이거나 상기 터브(1)와 연통되어 있는 벨로우즈 호스(11)에도 세제가 가라앉으면서 고이게 된다.The detergent introduced into the drum 2 may be mixed with the wash water, but the detergent is also accumulated in the bellows hose 11 which is accumulated on the lower surface of the tub 1 or communicates with the tub 1.

이와 같이 세탁기의 세탁행정이 준비되면 상기 드럼(2)을 회전시키는 세탁행정을 시작하고, 상기 펌프 하우징(22)의 일측에 설치된 순환펌프(24)를 가동시킨다.When the washing stroke of the washing machine is prepared as described above, the washing stroke of rotating the drum 2 is started, and the circulation pump 24 installed at one side of the pump housing 22 is operated.

이때, 상기 세탁기의 제어부(미도시)에 순환펌프(24)가 작동되는 시간을 미리 설정함으로써 상기 순환펌프(24)를 세탁행정 중에 계속해서 작동시킬 수도 있으며, 상기 순환펌프(24)를 세탁행정이 수행되는 중에 소정의 주기마다 작동시킬 수도 있다.At this time, by setting the operation time of the circulation pump 24 in the control unit of the washing machine in advance, it is also possible to continue to operate the circulation pump 24 during the washing stroke, the circulation pump 24 to the washing stroke It may be operated at predetermined intervals during this operation.

또한, 상기 터브에 투입되는 세탁수의 온도에 따라 세제가 완전히 녹는 시간을 각각 제어부에 미리 설정하여, 상기 세탁행정시에 세제가 녹는 시간이 되면 상기 순환펌프를 소정 시간동안 동작시킬 수도 있다.In addition, according to the temperature of the washing water introduced into the tub, the detergent is completely dissolved in time set in advance in the control unit, when the detergent is dissolved time in the washing administration may operate the circulation pump for a predetermined time.

게다가, 상기 제어부에 세탁행정이 시작된 후 소정의 시간이 지나면 순환펌프를 동작시키도록, 제어부에 소정의 시간을 미리 설정할 수도 있다.In addition, a predetermined time may be set in advance in the control unit so that the circulating pump is operated when a predetermined time passes after the washing operation starts in the control unit.

상기 순환펌프(24)가 회전됨에 의해 펌프 하우징(22)에는 소정의 압력이 발생되고, 이러한 압력에 의해 펌프 하우징(22)에 유입되는 세탁수를 순환호스(24a)를 통해 터브(1)에 세탁수를 공급시킴으로써 세탁수를 순환시킨다..As the circulation pump 24 is rotated, a predetermined pressure is generated in the pump housing 22, and the washing water flowing into the pump housing 22 is supplied to the tub 1 through the circulation hose 24a by the pressure. Circulate the wash water by supplying the wash water.

즉, 도 3의 점선 화살표 방향과 같이 상기 터브(1)의 세탁수가 벨로우즈 호스(11)를 통해 펌프 하우징(22)에 유입되고, 상기 펌프 하우징(22)의 세탁수는 순환호스(24a)를 통해 터브(1)로 유동된다.That is, the washing water of the tub 1 flows into the pump housing 22 through the bellows hose 11 as shown by the dotted arrow in FIG. 3, and the washing water of the pump housing 22 passes through the circulation hose 24a. Flow through the tub (1).

상기 세탁수가 유동됨에 의해 벨로우즈 호스(11)에 침전한 세제는 세탁수를 따라 유동되므로, 상기 터브(1)에 투입된 모든 세제가 세탁물을 세탁하는데 사용되게 된다.Since the detergent precipitated in the bellows hose 11 by flowing the wash water flows along the wash water, all the detergent added to the tub 1 is used to wash the laundry.

따라서, 상기 터브(1)에 종래 보다 적은 양의 세제를 투입시키더라도 동일한 세척력을 얻을 수 있으므로, 세제로 인한 수질오염을 다소 감소시킬 수 있다.Therefore, even if a smaller amount of detergent is added to the tub 1 than the conventional one, since the same washing power can be obtained, water pollution due to the detergent can be somewhat reduced.

다음으로, 상기 세탁기가 세탁행정을 완료한 후에는 제어부의 제어에 의해 펌프 하우징(22)의 타측에 설치된 배수펌프(23)를 가동시킨다.Next, after the washing machine completes the washing stroke, the drain pump 23 installed on the other side of the pump housing 22 is operated by the control of the controller.

상기 배수펌프(23)가 가동되면, 도 3의 실선 화살표 방향과 같이 터브(1)에 수용된 세탁수가 벨로우즈 호스(11)를 통해 펌프 하우징(22)에 유입되고, 계속해서 펌프 하우징(22)에 유입된 세탁수는 배수펌프(23)의 작용에 의해 배수호스(23a)를 통해 외부로 배출된다.When the drain pump 23 is operated, the washing water contained in the tub 1 flows into the pump housing 22 through the bellows hose 11 as shown in the solid arrow direction of FIG. 3, and then continues to the pump housing 22. The introduced wash water is discharged to the outside through the drain hose 23a by the action of the drain pump 23.

상기와 같은 과정을 통해 터브(1)에 수용된 세탁수가 완전히 외부로 배출된 다음에는 상기 급수호스를 통해 깨끗한 물을 다시 터브(1)에 공급하고,상기 터브(1)에 공급된 물이 일정한 수위까지 도달되면 헹굼행정을 수행한다.After the wash water accommodated in the tub 1 through the above process is completely discharged to the outside, the clean water is supplied back to the tub 1 through the water supply hose, and the water supplied to the tub 1 has a constant water level. Rinse administration is carried out when reached.

이어, 상기 헹굼행정 후에 배수펌프를 이용하여 세탁수를 완전히 배출시키고, 계속해서 드럼(2)을 고속으로 회전시켜 탈수행정을 수행하여 세탁물의 세탁을 완전히 종료한다.Subsequently, after the rinsing stroke, the washing water is completely discharged using a drain pump, and the drum 2 is rotated at a high speed to perform the dehydration stroke to completely wash the laundry.

이상에서와 같이, 상기 드럼세탁기는 세탁수를 순환시키거나 외부로 배출시킬 때에 각각의 펌프를 작동시킴으로써 세제의 낭비와 환경오염을 보다 감소시킬 수 있다.As described above, the drum washing machine can further reduce the waste of the detergent and environmental pollution by operating the respective pumps when the washing water is circulated or discharged to the outside.

이상에서와 같이, 상기 펌프 하우징에 순환펌프와 배수펌프를 각각 설치함으로써 세탁기가 세탁행정으로 운전되는 중에도 세탁수를 순환시킴으로써 상기 세탁기에 투입된 세제가 모두 세탁물을 세탁하는데 이용되도록 하였다.As described above, the circulation pump and the drain pump are respectively installed in the pump housing to circulate the washing water even while the washing machine is operated in the washing stroke so that all the detergents put into the washing machine are used to wash the laundry.

이에 따라, 동일한 세척력을 위해 보다 적은 양의 세제를 사용할 수 있으므로 세제에 의한 수질오염을 보다 감소시킬 수 있다.Accordingly, since less detergent can be used for the same washing power, water pollution by the detergent can be further reduced.
