본 발명은 드럼세탁기에 관한 것으로서, 더욱 상세하게는 세탁시의 급수량 및 전력소모를 줄일 수 있는 새로운 방식의 세탁제어방법에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to a washing method of a new method that can reduce the amount of water and power consumption during washing.

일반적으로, 세탁기는 드럼이 수직방향으로 세워진 펄세이터 타입 세탁기와, 상기 드럼이 대략 수평방향으로 눕혀진 드럼 타입 세탁기(드럼세탁기라 통칭함)로 크게 구분된다.In general, a washing machine is roughly divided into a pulsator type washing machine in which a drum is set in a vertical direction, and a drum type washing machine (collectively referred to as a drum washing machine) in which the drum is laid in a substantially horizontal direction.

여기서, 상기 드럼세탁기는 전술한 바와 같이 드럼이 수평방향으로 눕혀져 있기 때문에 드럼 내부에 투입된 세탁물을 드럼의 회전시 위로 끌어올려 낙하시키는 방식으로 세탁을 수행하게 된다.Here, since the drum washing machine is laid down in the horizontal direction as described above, the drum washing machine performs washing by pulling up and dropping the laundry put into the drum when the drum is rotated.

또한, 상기한 드럼세탁기 중 세탁물의 세탁 및 탈수 기능뿐만 아니라 건조 기능까지 수행할 수 있도록 한 건조 겸용 드럼세탁기도 최근에는 그 수요가 점차 증가하고 있다.In addition, the demand of the combined drying drum washing machine that can perform not only the washing and dehydration function of the laundry in the drum washing machine but also a drying function has been gradually increased in recent years.

그리고, 드럼세탁기에는 드럼이 완전히 수평하게 누운 타입의 드럼세탁기와, 드럼이 수평면에 대해 일정각도 기울어진 경사형의 드럼세탁기가 있다.The drum washing machine includes a drum washing machine of a type in which the drum is completely horizontal, and an inclined drum washing machine in which the drum is inclined at an angle with respect to the horizontal plane.

도시한 도 1을 참조하여 일반적인 드럼세탁기의 개략적 구조를 살펴보면, 상기 드럼세탁기는 터브(1)와, 상기 터브(1) 내부에 회전 가능하게 장착된 드럼(2)과, 터브(1)와 드럼(2) 사이의 공간 하부에 설치되어 세탁에 사용되는 세탁수를 가열하는 세탁히터(3)와, 상기 터브(1)에 채워진 세탁수를 순환시키도록 터브(1) 외측에 설치되는 순환덕트(4)와, 상기 순환덕트(4) 상에 설치되는 순환펌프(5)로 구성된다.Referring to the schematic structure of a general drum washing machine with reference to FIG. 1, the drum washing machine includes a tub 1, a drum 2 rotatably mounted inside the tub 1, a tub 1 and a drum. (2) a washing heater (3) installed in the lower part of the space between the two to heat the washing water used for washing, and a circulation duct installed outside the tub (1) to circulate the washing water filled in the tub ( 4) and a circulation pump 5 installed on the circulation duct 4.

이 때, 드럼(2) 내부 공간과 터브(1)는 드럼에 형성된 통공(미도시)을 통해 연통되며, 상기 세탁히터(3)와 더불어 터브(1)와 드럼(2) 사이의 공간에는 세탁수의 온도를 측정하는 써미스터(6)가 설치된다.At this time, the inner space of the drum 2 and the tub 1 communicate with each other through a through hole (not shown) formed in the drum, and in addition to the washing heater 3, the tub 2 and the tub 2 are washed in the space between the tub 1 and the drum 2. Thermistor 6 for measuring the temperature of the water is provided.

즉, 써미스터(6)를 통해 측정된 온도에 근거하여 세탁히터(3)를 온/오프 제 어함으로써 세탁수를 원하는 온도로 조절하게 된다.That is, the washing water is controlled to a desired temperature by controlling the washing heater 3 on / off based on the temperature measured by the thermistor 6.

한편, 터브(1)를 감싸도록 설치되는 아웃케이스와, 상기 터브(1) 내측으로 세탁수를 공급하는 급수수단 및 드럼(2)을 구동시키는 구동 수단등은 도시를 생략한다.On the other hand, the outer case is installed so as to surround the tub (1), the water supply means for supplying the wash water into the tub (1) and the driving means for driving the drum (2) and the like are omitted.

최근에는 상기한 구동 수단 대신, 터브(1) 후벽부에 장착되어 드럼(2)에 직접적으로 모터의 구동력이 전달되는 직결식의 BLDC모터가 많이 적용되고 있는 실정이다.In recent years, many direct-connected BLDC motors are applied to the rear wall of the tub 1 instead of the driving means so that the driving force of the motor is directly transmitted to the drum 2.

이와 같이 구성된 기존의 드럼세탁기를 위한 세탁시에는 세탁을 위한 급수후, 세탁히터(3)를 온시켜 세탁수를 소정온도까지 데운 후에 드럼(2)을 회전시켜 세탁을 행하게 된다. 물론 세탁을 위한 급수시 세제도 공급된다.When washing for the conventional drum washing machine configured as described above, after washing water for washing, the washing heater 3 is turned on to warm the washing water to a predetermined temperature, and the drum 2 is rotated to perform washing. Of course, detergents are also supplied when washing water.

즉, 기존의 세탁방식에 따르면, 급수된 물이 데워지고, 이렇게 데워진 물에 적셔져서 옷감이 데워지고, 이 상태에서 드럼(2)이 회전함에 따라 옷감의 오염분리가 가능해진다.That is, according to the conventional washing method, the water supplied is warmed, the cloth is heated by being soaked in the warmed water, and in this state, the separation of the cloth becomes possible as the drum 2 rotates.

그러나, 이와 같은 종래의 세탁제어방법은 다음과 같은 단점이 있다.However, the conventional laundry control method has the following disadvantages.

먼저, 세탁을 위한 초기 급수 후에 세탁포의 함습에 의한 수위감소로 인하여 세탁히터(3)가 수면 밖으로 노출되는 것을 방지하기 위해 초기 급수량을 충분하게 하여야 하기 때문에 물이 낭비되는 문제점이 있었다.First, there is a problem in that water is wasted because the initial amount of water must be sufficient to prevent the washing heater 3 from being exposed out of the water due to the decrease in the water level due to the humidity of the washing cloth after the initial water for washing.

이로 인해 급수량이 많아 에너지 소모도 많아지며 세탁시간이 길어지는 단점이 있었다.As a result, the amount of water supplied increases energy consumption and the washing time is long.

또한, 세탁을 위한 초기 급수 후 세탁이 완료될 때까지 세탁히터(3)를 계속 온시켜 세탁을 수행하기 때문에, 에너지 소모가 더욱 많아지는 문제점이 있었다.In addition, since the washing is continued by turning on the washing heater 3 until the washing is completed after the initial water supply for washing, there is a problem in that energy consumption is increased.

본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 드럼 내부로 공급되는 물의 양을 절약함과 더불어 많은 양의 물을 히팅함에 따른 에너지 소모 및 세탁시간의 지연을 해소할 수 있는 드럼세탁기의 세탁제어방법을 제공하고자 한 것이다.The present invention is to solve the above-mentioned problems, washing control of the drum washing machine that can save the amount of water supplied into the drum and can solve the energy consumption and delay of the washing time by heating a large amount of water It was intended to provide a way.

상기한 목적을 달성하기 위해, 본 발명은 드럼 내부로 투입된 세탁물의 양을 감지하는 포량감지단계와;상기 감지된 포량에 따라 터브 내측으로 급수를 수행하는 초기급수단계와;상기 터브의 수위주파수의 변화값이 설정된 변화값을 초과할 때마다, 상기 터브 내측으로 재급수를 수행하는 재급수단계와;상기 재급수단계가 완료될 때마다, 히터에 전원을 인가하여 상기 터브 내의 물을 설정온도까지 가열하면서 세탁을 수행하는 가열세탁단계를 포함하여 구성됨을 특징으로 하는 드럼세탁기의 세탁제어방법을 제공한다.In order to achieve the above object, the present invention is a quantity detection step of detecting the amount of laundry put into the drum; Initial water supply step of performing a water supply to the inside of the tub according to the detected quantity; and the water level frequency of the tub Whenever the change value exceeds the set change value, the water supply step of re-water supply to the inside of the tub; When the water supply step is completed, by applying power to the heater to the water in the tub to the set temperature It provides a laundry control method for a drum washing machine comprising a heating washing step of performing a washing while heating.

이와 같이 구성된 본 발명의 실시예를 첨부도면 도 2 내지 도 4를 참조하여 상세히 설명하면 다음과 같다.An embodiment of the present invention configured as described above will be described in detail with reference to FIGS. 2 to 4 as follows.

도 2는 본 발명의 일실시예에 따른 드럼세탁기의 세탁제어방법을 나타낸 흐름도이고, 도 3a 내지 도 3g는 본 발명의 세탁제어방법에 따른 동작과정을 나타낸 도면이며, 도 4는 본 발명의 세탁제어방법을 나타낸 순서도이다.2 is a flowchart illustrating a washing control method of a drum washing machine according to an embodiment of the present invention, Figures 3a to 3g is a view showing the operation process according to the washing control method of the present invention, Figure 4 is a laundry of the present invention A flowchart showing the control method.

먼저, 도 1을 참조하면, 본 발명의 드럼세탁기는, 터브(1) 내부에 회전 가능 하게 장착된 드럼(2)과, 상기 터브(1)와 드럼(2) 사이의 공간 하부에 설치되어 세탁에 사용되는 세탁수를 가열하는 히터(3)와, 상기 터브(1)에 채워진 세탁수를 순환시키도록 터브(1) 외측에 설치되는 순환덕트(4)와, 상기 순환덕트(4) 상에 설치되는 순환펌프(5)와, 상기 히터(3)와 더불어 터브(1)와 드럼(2) 사이의 공간에 설치되어 세탁수의 온도를 측정하는 써미스터(6)를 포함하여 구성된다.First, referring to Figure 1, the drum washing machine of the present invention, the drum (2) rotatably mounted inside the tub (1), and installed in the lower portion of the space between the tub (1) and the drum (2) to wash On the heater (3) for heating the wash water to be used for, the circulating duct (4) provided outside the tub 1 to circulate the wash water filled in the tub (1), and on the circulating duct (4) And a thermistor 6 installed in the space between the tub 1 and the drum 2 together with the heater 3 to measure the temperature of the wash water.

이와 같이 구성된 드럼세탁기를 이용한 세탁제어방법의 일실시예를 첨부된 도 2 내지 도 4를 참조하여 설명하면 다음과 같다.An embodiment of a washing control method using a drum washing machine configured as described above will be described with reference to FIGS. 2 to 4.

도 2 내지 도 4에 도시된 바와 같이, 본 발명의 일실시예에 따른 드럼세탁기의 세탁제어방법은, 드럼(2) 내부로 투입된 세탁물의 양을 감지하는 포량감지단계(S10)와, 상기 감지된 포량에 따라 터브(1) 내측으로 급수를 수행하는 초기급수단계(S20)와, 상기 터브(1)의 수위주파수의 변화값(Δh)이 설정된 변화값(ΔH)을 초과할 때마다 상기 터브(1) 내측으로 재급수를 수행하는 재급수단계(S40)와, 상기 재급수단계(S40)가 완료될 때마다 히터(3)에 전원을 인가하여 상기 터브(1) 내 물의 온도가 설정온도(T1)를 초과할 때까지 가열하면서 세탁을 수행하는 가열세탁단계(S50)를 포함하여 구성된다.As shown in Figure 2 to 4, washing control method of the drum washing machine according to an embodiment of the present invention, a quantity detection step (S10) for detecting the amount of laundry put into the drum (2), the detection The initial water supply step (S20) for supplying water into the tub 1 in accordance with the prescribed amount, and each time the change value (Δh) of the water level frequency of the tub 1 exceeds the set change value (ΔH) (1) Re-supply step (S40) to perform the re-water feed inward, and each time the re-supply step (S40) is completed by applying power to the heater (3) the temperature of the water in the tub 1 is set temperature It comprises a heat washing step (S50) to perform the washing while heating until it exceeds (T1).

여기서, 상기 초기급수단계(S20)와 상기 재급수단계(S40) 사이와, 상기 가열세탁단계(S50)가 완료된 시점과 상기 재급수단계(S40)가 다시 시작되는 시점 사이에는, 각각 상기 터브(1)에 채워진 세탁수를 순환펌프(5)로 펌핑하여 순환시키면서 세탁을 수행하는 순환세탁단계(S30,S60)가 각각 더 구비된다.Here, between the initial water supply step (S20) and the rewatering step (S40), and when the heating and washing step (S50) is completed and the time when the rewatering step (S40) is restarted, respectively, the tub ( 1 is further provided with a circular washing step (S30, S60) for performing the washing while circulating by pumping the wash water filled in the circulation pump (5).

또한, 상기 터브(1)의 수위주파수의 변화값(Δh)이 설정된 변화값(ΔH) 이하 일 경우, 상기 히터(3)에 전원을 인가하여 상기 터브(1) 내의 물을 목표온도(T2)까지 가열하면서 설정된 시간동안 세탁을 수행하는 최종세탁단계(S70)를 더 포함하여 구성된다.In addition, when the change value Δh of the water level frequency of the tub 1 is equal to or less than the set change value ΔH, power is applied to the heater 3 to supply water in the tub 1 to a target temperature T2. It further comprises a final washing step (S70) to perform the washing for a set time while heating up.

한편, 상기 최종세탁단계(S70)의 목표온도(T2)는 상기 가열세탁단계(S50)의 설정온도(T1)보다 크게 설정되는 것이 바람직하다.On the other hand, the target temperature (T2) of the final washing step (S70) is preferably set larger than the set temperature (T1) of the heating washing step (S50).

이 때, 상기 가열세탁단계(T1)의 설정온도(T1)는 상기 터브(1)의 수위주파수 변화값(Δh)이 설정된 수위주파수 변화값(ΔH) 이상이 되기 전까지 히터에 의해 물이 가열되어 설정된 온도임이 바람직하다.
왜냐하면, 터브(1)의 수위주파수 변화값(Δh)이 설정된 수위주파수 변화값(ΔH) 이상이 된다고 하는 것은 터브내의 수위가 줄어듦을 뜻하는 것이므로, 상기 터브(1)의 수위주파수 변화값(Δh)이 설정된 수위주파수 변화값(ΔH) 이상 될 때까지 히터에 의해 물이 가열되면 히터가 수면 밖으로 노출되는 문제가 발생될 수 있기 때문이다.At this time, the water is heated by the heater until the set temperature (T1) of the heating washing step (T1) until the water level frequency change value (Δh) of the tub 1 is equal to or greater than the set water level frequency change value (ΔH). It is preferably at a set temperature.
Because the water level frequency change value Δh of the tub 1 is equal to or higher than the set water level frequency change value ΔH, it means that the water level in the tub is reduced, and thus the water level frequency change value Δh of the tub 1 is reduced. This is because when the water is heated by the heater until the water level frequency change value (ΔH) is greater than or equal to the set water level frequency change value (ΔH), the heater may be exposed out of the water surface.

그리고, 상기 초기급수단계(S20)에서 급수가 완료되는 수위는 상기 재급수단계(S40)에서 급수가 완료되는 수위보다 높게 설정되는 것이 바람직하다.And, the water level at which the water supply is completed in the initial water supply step (S20) is preferably set higher than the water level is completed in the water supply step (S40).

이하, 상기와 같이 구성된 본 발명의 세탁제어방법에 따른 세탁과정을 설명하면 다음과 같다.Hereinafter, the washing process according to the laundry control method of the present invention configured as described above is as follows.

먼저, 사용자가 세탁물을 상기 드럼(2) 내부에 투입하고 드럼세탁기를 작동시키면, 상기 드럼(2) 내부에 수용된 세탁물의 양을 감지하여 감지된 포량에 맞는 급수량만큼 터브(1)로의 초기 급수를 수행하게 된다.First, when a user puts laundry into the drum 2 and operates a drum washing machine, the user may sense the amount of laundry contained in the drum 2 to supply initial water to the tub 1 by the amount of water corresponding to the detected amount of water. Will be performed.

이어, 초기 급수가 완료된 다음에는 터브(1) 내부의 물을 순환펌프(5)를 써서 펌핑하여 순환시키게 된다.Subsequently, after the initial water supply is completed, the water inside the tub 1 is circulated by pumping using the circulation pump 5.

한편, 초기 급수 완료 후 물을 펌핑하여 순환시킬 때 드럼(2)의 회전이 동시에 이루어짐이 바람직하다.On the other hand, when the water is pumped and circulated after completion of the initial water supply, the drum 2 is preferably rotated at the same time.

그리고, 상기와 같이 터브(1) 내부의 물을 순환시켜 세탁하는 중에 세탁물이 물을 흡수함에 따라 터브(1) 내부의 물은 점차 줄어든다.Then, as the laundry absorbs the water while circulating the water inside the tub 1 as described above, the water inside the tub 1 gradually decreases.

그리하여, 상기 터브(1) 내부의 수위에 따른 수위주파수의 변화값(Δh)이 설정된 수위주파수의 변화값(ΔH)을 초과하게 되면, 상기 터브(1)로의 재급수를 수행한다.Thus, when the change value Δh of the water level frequency according to the water level inside the tub 1 exceeds the set value ΔH of the water level frequency, re-water supply to the tub 1 is performed.

상기 터브(1)로의 재급수가 완료되면, 히터(3)의 전원을 온(ON)시켜 터브(1) 내부의 물을 설정온도(T1)까지 가열한다.When the water supply to the tub 1 is completed, the power of the heater 3 is turned on to heat the water inside the tub 1 to the set temperature T1.

이후, 상기 터브(1) 내부의 물의 온도(T)가 설정온도(T1)를 초과하게 되면, 상기 히터(3)의 전원을 오프(OFF)시키고, 상기 터브(1) 내부의 물을 순환펌프(5)를 사용하여 순환시킴과 아울러 드럼(2)을 회전시키면서 세탁을 수행한다.Then, when the temperature (T) of the water in the tub 1 exceeds the set temperature (T1), the power of the heater (3) is turned off (OFF), the water in the tub (1) circulating pump Circulation is carried out using (5) and washing is performed while rotating the drum (2).

그리고, 상기 터브(1)로의 재급수과정과 터브(1) 내부의 물의 가열과정 및 터브(1) 내부의 물을 순환시키는 과정을 반복적으로 수행하면서 세탁과정이 진행된다.Then, the washing process proceeds while repeatedly performing the rewatering process to the tub (1), the heating process of the water in the tub (1) and the circulation of the water in the tub (1).

이 때, 상기 터브(1) 내부의 수위에 따른 수위주파수의 변화값(Δh)이 설정된 수위주파수의 변화값(ΔH) 이하이면, 상기와 같은 반복과정을 완료하고 상기 히터(3)의 전원을 온시켜 상기 터브(1) 내부의 물을 가열한다.At this time, if the change value Δh of the water level frequency according to the water level inside the tub 1 is less than the set value ΔH of the water level frequency, the above-described repetition process is completed and the power of the heater 3 is turned off. The water inside the tub 1 is heated by turning on.

이후, 상기 터브(1) 내부의 물의 온도(T)가 목표온도(T2) 이상이 되면, 상기 히터(3)의 전원을 오프시키고, 설정된 시간 동안 드럼(2)을 회전시키면서 세탁을 수행한다.Thereafter, when the temperature T of the water inside the tub 1 becomes equal to or higher than the target temperature T2, the power of the heater 3 is turned off and washing is performed while rotating the drum 2 for a predetermined time.

그리고, 설정된 시간이 경과되면 상기 터브(1) 내부의 물을 배수펌프(미도시)를 작동시켜 배수하고, 배수가 완료되면 드럼(2)을 고속회전시켜 세탁물을 탈수 하면 세탁과정이 완료된다.When the set time elapses, the water inside the tub 1 is drained by operating a drain pump (not shown). When the draining is completed, the drum 2 is rotated at a high speed to dehydrate the laundry.

이와 같이 구성된 본 발명의 일실시예의 작용은 다음과 같다.The operation of one embodiment of the present invention configured as described above is as follows.

본 실시예에 따르면, 터브(1)의 재급수가 완료된 시점에서 터브(1) 내부의 물이 설정온도(T1)을 초과할 때까지만 히터(3)를 온시킴에 따라 히터에 전원을 공급하기 위한 에너지 소모를 줄일 수 있다.According to the present embodiment, the heater 3 is turned on only until the water inside the tub 1 exceeds the set temperature T1 at the time when the water supply of the tub 1 is completed. To reduce energy consumption.

또한, 상기와 같이 히터(3)를 주기적으로 온/오프시킴에 따라 세탁물의 함습에 의한 수위감소로 히터(3)가 수면 밖으로 노출되는 것을 방지할 수 있어, 초기 급수량 및 재급수량을 적게 할 수 있어, 세탁수를 절약할 수 있다.In addition, as the heater 3 is periodically turned on and off as described above, it is possible to prevent the heater 3 from being exposed to the outside of the water due to the decrease in the water level due to the humidity of the laundry, so that the initial water supply amount and the resupply water amount can be reduced. Thereby, washing water can be saved.

이상에서 설명된 바와 같이, 본 발명의 드럼세탁기 세탁제어방법은, 드럼 내부로 공급되는 물의 양을 절약함과 더불어 물을 히팅함에 따른 에너지 소모 및 많은 양의 물을 히팅함에 따른 세탁시간의 지연을 해소할 수 있게 된다.As described above, the drum washing machine washing control method of the present invention, while saving the amount of water supplied into the drum, the energy consumption of heating the water and the delay of the washing time due to heating a large amount of water It can be solved.
