The rinsing process is performed by rinsing laundry by continuously using hot water. Although the effect is increased, the water temperature during rinsing is lower than that during washing, and the washing water for washing the contaminated washing liquid that has infiltrated the laundry at high temperature is lowered. It is to solve the problem that a large amount of energy is consumed by the continuous hot water supply.

본 발명은 이와 같은 종래 문제점을 해결하기 위하여 열변형이 배제되는 수온하에서 온수를 사용해 세탁물 세탁후 초기에는 온수로 헹굼을 계속 실시하여 다음 헹굼시에는 냉수를 이용해 헹굼을 실시하므로서 헹굼효과를 향상시키면서도 에너지 소비를 줄이고 고온에 의한 세탁조 및 세탁물의 열변형을 방지하도록 한 것으로 세탁기에 적용한다.In order to solve the conventional problems, the present invention continues to rinse with warm water after washing the laundry using hot water under water temperature to avoid heat deformation, and then rinsing with cold water during the next rinsing while improving the rinsing effect and energy. It is applied to the washing machine to reduce the consumption and prevent heat deformation of the washing tank and the laundry due to high temperature.

Description

세탁기의 온수 절약방법How to save hot water in the washing machine

제 1도는 종래 세탁기의 온수 세탁방법을 보인 플로우챠트.1 is a flowchart showing a method of washing hot water of a conventional washing machine.

제 2도는 온수 세탁시 세탁물의 헹굼효과를 보인 그래프.2 is a graph showing the rinsing effect of laundry when washing hot water.

제 3도는 본 발명의 온수 절약방법에 의한 세탁 제어과정의 플로우챠트.3 is a flow chart of the washing control process according to the hot water saving method of the present invention.

본 발명은 세탁물이 세탁 및 헹굼효과를 향상시키면서 온수를 절약하여 에너지 절약 및 세탁 비용을 절감시키도록 한 세탁기의 온수 절약 방법에 관한 것이다.The present invention relates to a method for saving hot water of a washing machine in which laundry is used to save hot water while improving washing and rinsing effects, thereby saving energy and washing costs.

종래 세탁기의 온수 세탁방법은 제 1 도에 도시된 바와 같이, 사용자가 세탁기 사용시 세탁수를 온수로 선택하여 포량센싱 수위까지 온수를 급수한 후 포량센싱에 의해 감지수위까지 온수를 급수하여 세탁을 실시한다.In the conventional method for washing hot water of a washing machine, as shown in FIG. 1, when a user uses the washing machine, the user selects the washing water as hot water to supply hot water up to the level of the quantity sensing, and then performs the washing by supplying the hot water to the sensing level by the quantity sensing. do.

세탁이 완료되었으면 탈수를 진행한 후 다시 감지된 수위까지 냉수와 온수를 동시에 급수한 후 탈수된 세탁물의 헹굼을 실시한다.After washing is completed, dehydration is performed, and then cold water and hot water are supplied to the detected water level at the same time, and then rinsed the dehydrated laundry.

헹굼이 완료되었으면 최종탈수를 진행하여 탈수가 완료되었으면 경보음을 울려 사용자에게 세탁이 완료되었음을 알린다.If the rinsing is completed, proceed to the final dehydration and if the dehydration is completed, an alarm sounds to inform the user that the washing is complete.

한편, 온수급수시 세탁기 내부에 장착된 수온센서에 의해 계속 급수된 수온을 감지하여 일정온도(약 70℃) 이상이 되면 경보음을 발생시켜 세탁기의 동작을 중지시켜 세탁조 및 수지물의 열변형을 방지하도록 한다.On the other hand, when hot water is supplied, the water temperature sensor continuously installed by the washing machine detects the water temperature and generates an alarm sound when it reaches a certain temperature (about 70 ℃) to stop the washing machine and prevent thermal deformation of the washing tank and resin. Do it.

그러나 종래 세탁기는 세탁물 세탁시 선택한 온수와 세탁완료후 헹굼시 급수된 온수의 온도차에 의해 헹굼효과가 반감된다.However, in the conventional washing machine, the rinsing effect is halved by the temperature difference between the hot water selected when washing laundry and the hot water supplied when rinsing after washing.

즉, 제 2도에서와 같이 세탁물 헹굼시 온수를 계속 사용하여 세탁헹굼을 실시하여 헹굼효과를 상승시키지만 세탁시보다 헹굼시의 수온이 더 낮게 때문에 고온에서 세탁물에 침투했던 오염된 세액을 씻어내는 세척물이 저하되었고, 세탁시 계속 급수된 온수의 온도상승에 의해 세탁조 및 수지물이 열변형되며, 계속된 온수공급에 의해 많은 에너지가 소비되는 문제점이 있었다.In other words, as shown in FIG. 2, the washing rinsing effect is increased by continuously using hot water to rinse the laundry, but the rinsing effect is increased. The water was lowered, and the washing tank and the resin water were thermally deformed by the temperature rise of the hot water continuously supplied during washing, and a lot of energy was consumed by the continuous hot water supply.

본 발명은 이와 같은 종래 문제점을 해결하기 위하여 열변형이 배제되는 수온하에서 온수를 사용해 세탁물 세탁후 초기에는 온수로 헹굼을 계속 실시하여 다음 헹굼시에는 냉수를 이용해 헹굼을 실시하므로서 헹굼효과를 향상시키면서도 에너지 소비를 줄이고 고온에 의한 세탁조및 세탁물의 열변형을 방지하는데 그 목적이 있는 것으로 첨부된 도면에 의하여 본 발명의 작용효과를 설명하면 다음과 같다.In order to solve the conventional problems, the present invention continues to rinse with warm water after washing the laundry using hot water under water temperature to avoid heat deformation, and then rinsing with cold water during the next rinsing while improving the rinsing effect and energy. When explaining the operation and effect of the present invention by the accompanying drawings that the purpose is to reduce the consumption and to prevent the thermal deformation of the washing tank and the laundry due to high temperature.

본 발명 세탁기의 온수 절약방법은 제 3도에 도시된 바와 같이 , 사용자가 세탁물을 세탁하기 위해 먼저 세탁기에 장착된 온수 절약키를 온하면 온수 밸브를 통해 온수가 세탁조로 급수된다.In the hot water saving method of the washing machine according to the present invention, when the user turns on the hot water saving key mounted on the washing machine to wash the laundry, the hot water is supplied to the washing tank through the hot water valve.

온수 급수후, 급수개시 1분후 온도(T1)와 급수개시 2분후 온도(T2)를 급수개시 직후 온도(T0)와 비교하여 일정온도(약 3℃)이하면 냉수가 공급되는 것으로 판단하여 사용자에게 경고음을 울린 후 세탁기의 동작을 정지시킨다.After supplying hot water, compare the temperature (T1) after 1 minute of water supply and the temperature (T2) after 2 minutes of water supply to the temperature (T0) immediately after water supply. After the alarm sounds, the washing machine stops operating.

한편, 급수개시후 온수온도가 급수개시 직후 온도(T0)와 비교하여 일정온도(약 3℃)이상이면 온수가 정상적으로 급수되고 있는 것으로 판단한다.On the other hand, when the hot water temperature after the start of water supply is more than a predetermined temperature (about 3 ℃) compared to the temperature (T0) immediately after the start of water supply is determined that the hot water is normally supplied.

이때 급수 개시 1분후 온도(T1)를 설정온도 (약 40℃)와 비교하여 설정온도 이상이면 온수밸브를 오프시키고 냉수밸브를 온시켜 급수된 온수가 설정온도 이하가 되도록 한다.At this time, compare the temperature (T1) with the set temperature (about 40 ℃) one minute after the start of water supply, if the set temperature is over, turn off the hot water valve and turn on the cold water valve so that the hot water supplied is below the set temperature.

이후 매 10초마다의 온도(Ti)를 감지하여 급수된 온수가 일정온도(약 30℃, -40℃ )를 유지하였으면 포량센싱 수위에 도달하였는지 판단하여 포량센싱 수위에 도달하였으면 급수를 중지하고, 포량센싱 수위에 도달하지 않았으면 계속 급수를 실시하며, 매 10초마다의 온도(Ti)를 감지하여 설정온도 (약 40℃)이하에서 포량센싱 수위에 도달하였는지 판단하여 포량센싱 수위에 도달하였으면 급수를 중지하고 포량센싱 후 초기에는 냉수와 온수를 동시에 급수를 실시하여 메 10초마다 감지한 온수온도(Ti)가 설정온도 (약 40℃)이하면 포량센싱 수위대신 포량센싱 감지수위에 도달하였는지 감지하여 포량센싱 감지수위에 도달하였으면 급수를 중지하고 세탁을 실시한다.After detecting the temperature (Ti) every 10 seconds, if the supplied hot water maintains a constant temperature (about 30 ℃, -40 ℃), it is determined whether or not to reach the level of the capacity sensing level, and stop the water supply when the level of the quantity sensing level is reached, If the quantity of water level is not reached, continue to supply water, and detect the temperature (Ti) every 10 seconds to determine whether the quantity of water level is reached below the set temperature (about 40 ℃). After stopping the quantity of water and initially supplying cold water and hot water simultaneously, if the detected hot water temperature (Ti) is less than the set temperature (about 40 ℃) every 10 seconds, it detects whether the quantity of sensing of the quantity of water is reached instead of the quantity of water. When the water level is detected, stop the water supply and wash.

세탁이 완료되었으면 세탁물을 탈수한 후 다시 온수를 급수하여 포량센싱없이 포량센싱 감지 수위까지 도달하였으면 급수를 중지한 후 탈수된 세탁물을 다시 1회 헹굼을 실시한다.When the laundry is completed, the laundry is dehydrated and water is supplied again to reach the level of the sensing capacity without sensing the quantity of water. After stopping the water supply, rinse the dehydrated laundry once again.

이후 다시 헹굼이 완료된 세탁물을 탈수한 후 탈수가 완료되었으면 2회 헹굼부터는 냉수를 급수한다.After dehydrating the laundry after rinsing again, if dehydration is complete, rinsed twice from the cold water.

급수된 냉수가 포량센싱 수위에 도달하였으면 다시 헹굼 및 탈수를 실시한 후 경고음을 통해 세탁물 세탁 및 탈수가 완료되었음을 알려 세탁기의 동작을 정지시킨다.If the cold water reaches the level of the volume sensing level, the rinsing and dehydration is performed again, and the washing machine stops the operation by notifying the laundry washing and dehydration through a warning sound.

이상에서 설명한 바와 같이 세탁물 헹굼시 헹굼 초기 (1회)만 온수를 사용해 헹굼을 실시한 후 다시 세탁물을 헹굼시에는 냉수를 사용해 헹굼을 실시하므로서 온수를 공급하기 위한 에너지를 절감하면서 세탁물의 세탁효율을 향상 시킬 수 있는 효과가 있다.As described above, when rinsing laundry, the initial rinsing cycle (only once) is rinsed using hot water, and when rinsing the laundry again, cold water is used to rinse the laundry to improve the washing efficiency of the laundry while saving energy for supplying hot water. It can be effected.
