At this time, the preliminary washing process is completed by repeatedly performing the process of washing and stopping the dishes loaded in the loading means inside the dishwasher using the washing water and the detergent supplied from the outside. This washing operation is then performed. At this time, this washing administration is completed by first draining the washing water used in the preliminary washing stroke, heating the re-supplied washing water using a heater (not shown) inside, and washing the dishes by spraying the heated washing water and detergent. And a preliminary rinse stroke is performed. At this time, the preliminary rinsing stroke is a process of removing contaminants such as food residues attached to the dishes by draining the washing water used in the washing stroke and repeating the process of rinsing the dishes with the replenished water. This rinse stroke is then performed. At this time, the rinsing stroke is completed by draining the washing water used in the preliminary rinsing stroke, heating the re-watered washing water to a high temperature using a heater, and spraying the heated washing water to remove food residues or detergents remaining in the dishes. do.
도 2는 종래의 식기세척기의 행정제어방법을 나타낸 플로우챠트로써, 도 1을 참조하여 설명한 바와 같이, 예비세척행정을 수행한후 예비세척행정에서 사용된 세척수를 배수하고 가열된 세척수를 이용하여 식기를 세척하는 세척행정을 수행하기 위해 외부에서 세척수를 급수한다(S11). 이어서 급수된 세척수가 정상수위인지 판단하여(S12), 정상수위이면 급수를 종료한다(S13). 그리고 세척모터를 구동시키고(S14), 가열세척을 수행하기 위한 설정온도에 도달하였는지 여부를 판단한다(S15). 이어서 설정온도에 도달하지 않았으면 히터를 0g온0h 시킨다(S17). 그리고 설정온도에 도달하였는지를 계속 판단하여 설정온도에 도달하면 히터를 0g오프0h시킨다(S16). 이때 세척모터의 구동에 의해 가열세척행정은 수행중이다. 이어서 가열세척을 위해 설정된 시간이 경과하였는지 판단하여(S18), 설정시간이 경과하지 않았으면 세척수의 온도가 설정온도 이하로 낮아졌는지 판단하여(S15), 설정온도 이하이면 다시 히터를 0g온0h시켜(S17) 세척수의 온도를 설정온도 이상으로 유지시킨다. 이때 세척수의 온도가 설정온도에 도달하면 히터는 0g오프0h된다. 그리고 설정시간이 경과하였으면 세척모터 및 히터를 0g오프0h시키고(S19) 가열세척에 사용된 세척수를 배수한다(S20). 이때 히터를 0g오프0h시키는 이유는 설정시간이 경과하였다 하더라도 세척수의 온도가 설정온도 이하로 되면 히터가 재동작할 수 있기 때문이다. 이어서 정상수위까지 재급수하고(S21), 다음행정 즉, 예비헹굼행정을 수행한다. 이때 예비헹굼행정은 재급수된 세척수를 가열하지 않은 상태로 사용한다.FIG. 2 is a flow chart illustrating a conventional method for controlling a dishwasher. As described with reference to FIG. 1, after performing a preliminary washing stroke, the washing water used in the preliminary washing stroke is drained and the dish is heated using the heated washing water. Water the washing water from the outside to perform the washing stroke to wash (S11). Subsequently, it is determined whether the supplied water is normal water level (S12), and when the normal water level, the water supply is terminated (S13). Then, the washing motor is driven (S14), and it is determined whether or not the set temperature for heating and washing has been reached (S15). Subsequently, if the set temperature is not reached, the heater is turned on at 0g at 0h (S17). Then, it is determined whether the set temperature has been reached, and when the set temperature is reached, the heater is turned off by 0 g (0 h) (S16). At this time, the heating and washing stroke is being performed by driving the washing motor. Subsequently, it is determined whether the set time for heating and cleaning has elapsed (S18). If the set time has not elapsed, it is determined whether the temperature of the washing water is lower than or equal to the set temperature (S15). (S17) Maintain the temperature of the washing water above the set temperature. At this time, when the temperature of the washing water reaches the set temperature, the heater is turned off 0g 0h. When the set time has elapsed, the washing motor and the heater are 0g off 0h (S19), and the washing water used for heating and washing is drained (S20). The reason why the heater is 0g off 0h is that the heater may be restarted when the temperature of the washing water is lower than the set temperature even if the set time has elapsed. Subsequently, the water is resupplied to the normal water level (S21), and the next stroke, that is, the preliminary rinsing stroke is performed. At this time, the pre-rinse stroke is used without reheating the wash water.
종래의 기술에 따른 식기세척기의 행정제어방법은 가열헹굼 행정 수행후 가열헹굼 행정에서 사용된 고온의 세척수에 의해 고온으로 가열된 식기에 갑자기 차가운 세척수를 직접 분사하여 예비헹굼 행정을 수행하므로 급격한 온도변화에 의해 유리컵을 비롯한 얇은 그릇이 깨어지거나 금이가는 손상을 초래할 수 있는 문제점이 있다.In the conventional method of controlling the dishwasher according to the prior art, a sudden temperature change is performed by suddenly spraying cold washing water directly onto a dish heated to a high temperature by a high temperature washing water used in a heating rinsing stroke after performing a heating rinsing stroke. There is a problem that can cause a glass bowl, such as a broken or cracked damage by the glass.
따라서 본 발명은 이러한 종래의 문제점을 해결하기 위하여 안출한 것으로서 행정진행도중 급격한 수온 변화에 의해 발생할 수 있는 식기의 손상을 방지할 수 있도록 한 식기세척기의 행정제어방법을 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide an administrative control method for a dish washer that can prevent damage to the tableware which may be caused by a sudden change in water temperature during the administrative process.

본 발명은 식기세척기의 행정제어방법에 있어서, 가열된 세척수를 이용하여 본 세척행정 종료후 세척수중 일정량을 배수하는 단계, 배수 후 배수된 만큼의 세척수를 보충하는 과정을 일정회 반복하여 식기의 온도를 낮춘 다음 예비 헹굼행정을 수행하는 단계를 포함하여 이루어짐을 특징으로 한다.According to the present invention, in the administrative control method of the dishwasher, using the heated washing water, the step of draining a certain amount of the washing water after the completion of the washing operation, replenishing the washing water as much as the drained water after the draining is repeated the temperature of the tableware It characterized in that it comprises a step of lowering and then performing a preliminary rinsing stroke.
이하, 첨부된 도면을 참조하여 본 발명에 따른 식기세척기의 행정제어방법을 설명한다.Hereinafter, with reference to the accompanying drawings will be described an administrative control method of the dish washer according to the present invention.
도 3은 본 발명에 따른 식기세척기의 행정제어방법을 나타낸 플로우챠트이다.3 is a flow chart showing a stroke control method of the dish washing machine according to the present invention.
먼저, 예비세척행정을 수행한후 예비세척행정에서 사용된 세척수를 배수하고 가열세척행정을 수행하기 위해 외부에서 세척수를 급수한다(S31). 이어서 급수된 세척수가 정상수위인지 판단하여(S32), 정상수위이면 급수를 종료한다(S33). 그리고 세척모터를 구동시키고(S34), 가열세척을 수행하기 위한 설정온도에 도달하였는지 여부를 판단한다(S35). 이어서 설정온도에 도달하지 않았으면 히터를 0g온0h 시킨다(S37). 그리고 설정온도에 도달하였는지를 계속 판단하여 설정온도에 도달하면 히터를 0g오프0h시킨다(S36). 이때 세척모터의 구동에 의해 가열세척행정은 수행중이다. 이어서 가열세척에 상응하여 설정된 시간이 경과하였는지 판단하여(S38), 설정시간이 경과하지 않았으면 세척수의 온도가 설정온도 이하로 낮아졌는지 판단하여(S35), 설정온도 이하이면 다시 히터를 0g온0h시켜(S37) 세척수의 온도를 설정온도 이상으로 유지시킨다. 이때 세척수의 온도가 설정온도 이상이 되면 히터는 0g오프0h된다. 그리고 설정시간이 경과하였으면 세척모터 및 히터를 0g오프0h시킨다(S39). 이어서 종래의 문제점인 급격한 수온변화율을 감소시키기 위한 행정을 수행한다. 먼저 0gX0h 값을 초기화 한다(S40). 이때 0gX'값은 가열세척행정에 의해 가열된 식기의 온도를 낮추는 동작의 횟수를 의미한다. 그리고 가열세척행정에서 사용된 세척수를 모두 배수하지 않고 그중 약 1/3(20∼40%)만을 배수한 다음(S41), 정상수위까지 재급수한다(S42). 따라서 세척수의 온도는 배수량에 비례하여 낮아진다. 이때 본 발명에 따른 세척수의 온도는 가열된 식기의 온도에 비해서는 낮은 온도이고 종래의 기술에 따라 정상수위까지 급수된 세척수의 온도에 비해서는 높은 온도이다. 이어서 세척모터를 수초간 구동시켜(S43) 세척수를 식기에 분사함으로써 식기의 온도를 낮추는 동작을 수행한다. 그리고 0gX0h 값을 0g10h 증가시키고(S44), 0gX0h 값이 0g30h 이상인지 여부를 판단한다(S45). 이어서 그 판단결과 0gX0h 값이 0g30h 보다 작으면 상술한 식기의 온도를 낮추는 알고리즘으로 복귀하여 식기의 온도를 낮추는 동작을 반복수행한다. 즉, 세척수를 모두 배수하지 않고 그중 약 1/3 만을 배수한 다음(S41), 정상수위까지 재급수한다(S42). 이어서 세척모터를 수초간 구동시켜(S43) 세척수를 식기에 분사함으로써 식기의 온도를 낮추는 동작을 2회 반복수행한다. 그리고 각 회마다 0gX0h 값을 0g10h 증가시키고(S44), 0gX0h 값이 0g30h 이상인지 여부를 판단한다(S45). 이어서 그 판단결과 0gX0h값이 0g30h이상이면 세척모터를 0g오프0h시키고(S46), 세척수를 모두 배수한다(S47). 그리고 정상수위까지 급수하여(S48), 다음 행정 즉, 예비 헹굼행정을 수행한다.First, after performing the preliminary washing stroke, the washing water used in the preliminary washing stroke is drained and the washing water is externally supplied to perform the heating washing stroke (S31). Subsequently, it is determined whether the water supplied in the washing water is the normal water level (S32). Then, the washing motor is driven (S34), and it is determined whether or not the set temperature for performing the heating and washing is reached (S35). Subsequently, if the set temperature is not reached, the heater is turned on at 0g at 0h (S37). And it is determined whether the set temperature has been reached continuously when the set temperature is reached 0g off 0h (S36). At this time, the heating and washing stroke is being performed by driving the washing motor. Subsequently, it is determined whether the set time has elapsed according to the heating washing (S38). If the set time has not elapsed, it is determined whether the temperature of the washing water is lower than the set temperature (S35). (S37) to maintain the temperature of the washing water above the set temperature. At this time, when the temperature of the washing water is more than the set temperature, the heater is 0g off 0h. Then, if the set time has elapsed, the washing motor and the heater are turned off 0g 0h (S39). Subsequently, a stroke for reducing the rate of rapid water temperature change, which is a conventional problem, is performed. First, the 0gX0h value is initialized (S40). At this time, the value 0gX 'means the number of times of lowering the temperature of the dishes heated by the heating washing stroke. And without draining all of the washing water used in the heat washing stroke only about one third (20 to 40%) of the drain (S41), and then re-supplied to the normal water level (S42). Therefore, the temperature of the wash water is lowered in proportion to the drainage amount. At this time, the temperature of the washing water according to the present invention is a low temperature compared to the temperature of the heated dishware and a high temperature compared to the temperature of the washing water supplied to the normal water level according to the prior art. Subsequently, the washing motor is driven for several seconds (S43) to lower the temperature of the dish by spraying the washing water onto the dish. The 0gX0h value is increased by 0g10h (S44), and it is determined whether the 0gX0h value is 0g30h or more (S45). Subsequently, if the value of 0gX0h is smaller than 0g30h, the operation returns to the above-described algorithm for lowering the temperature of the dish and repeatedly performs the operation of lowering the temperature of the dish. That is, after draining only about one third of them without draining all the washing water (S41), the water is resupplied to the normal water level (S42). Subsequently, the washing motor is driven for several seconds (S43) to repeatedly perform the operation of lowering the temperature of the dish by spraying the washing water onto the dish. Each time 0gX0h is increased by 0g10h (S44), and it is determined whether the 0gX0h value is greater than or equal to 0g30h (S45). Subsequently, if the 0gX0h value is 0g30h or more as a result of the determination, the washing motor is 0g off 0h (S46) and all the washing water is drained (S47). Then, water is supplied to the normal water level (S48) to perform the next stroke, that is, a preliminary rinsing stroke.
상술한 바와 같이, 가열세척 행정 진행후 예비헹굼 행정을 수행함에 있어 가열세척행정에 의해 고온으로 가열된 식기에 저온의 세척수를 분사하여 급격한 온도변화를 초래하지 않고 부분 배수에 의해 일정비율로 그 온도가 낮아진 세척수를 식기에 분사함으로써 식기의 온도를 단계적으로 낮춘 다음, 저온의 세척수를 이용하는 행정을 수행하므로 식기의 급격한 온도변화에 따른 손상을 방지할 수 있는 것이다.As described above, in performing the preliminary rinsing stroke after the heating washing stroke is carried out, by spraying low-temperature washing water on the dishes heated to high temperature by the heating washing stroke, the temperature is kept at a constant rate by partial drainage without causing a sudden temperature change. By lowering the temperature of the dishes in a step by spraying the wash water is lowered to the next step, by performing a stroke using the low temperature wash water it is possible to prevent damage due to the rapid temperature change of the dishes.
본 발명에 따른 식기세척기의 행정제어방법은 가열세척 행정 수행후 세척수의 일정량을 배수하고 배수된 만큼의 세척수를 보충하여 감온된 세척수를 식기에 분사함으로써 식기의 온도를 단계적으로 낮춘 다음 저온의 세척수를 사용하는 행정을 수행하므로 식기의 손상 등을 방지하여 식기세척기의 신뢰성을 향상시킬 수 있는 효과가 있다.In the administrative control method of the dish washing machine according to the present invention, after performing a heating washing stroke, a predetermined amount of the washing water is drained, and the washing water is replenished as much as the drained water, thereby lowering the temperature of the dish by gradually lowering the temperature of the dish and then washing the cold water. Since the stroke is used, it is possible to prevent damage to the dishes and to improve the reliability of the dishwasher.
