Abstract

본 발명은 식기세척기에 관한 것으로, 특히 가열세척 또는 가열헴굼시 세척모터가 구속되었을 경우 히터과열로 인해 세척조가 열변형되는 것을 방지하고자 한 식기세척기의 가열에러 감지 방법에 관한 것이다.The present invention relates to a dishwasher, and more particularly, to a heating error detection method of a dishwasher intended to prevent the washing tank from being thermally deformed due to overheating of a heater when the washing motor is restrained during heating or heating.

종래의 식기세척기는 세척모터가 구속되면 세척수가 분사되지 못함에도 불구하고 히터는 계속구동되므로 히터 주위의 세척조가 열을 받게 되면, 온도감지부는 계속 세척수의 온도를 감지하지만 세척모터의 구속으로 세척수의 온도가 상승되지 못하는데 히터는 계속구동되므로 상기와 같이 세척조에만 일이 전달되어 세척조가 변형되는 문제점이 있었다.Conventional dishwashers keep the heater running even though the washing motor is not sprayed when the washing motor is constrained. Therefore, when the washing tank around the heater receives heat, the temperature sensing unit detects the temperature of the washing water but the restraint of the washing water Since the heater is continuously driven but the temperature is not increased, the work is delivered only to the cleaning tank as described above, so that the cleaning tank is deformed.

따라서 본 발명은 세척행정이 시작되면 설정수위만큼 급수를 행하고, 세척모터 및 히터를 구동시킨 후 초기 수온을 감지하고 설정시간의 경과유무를 검색하는 제1과정과, 상기 설정시간이 경과되기 이전에 감지되는 수온이 설정온도에 이르면 정상적인 가열로 판단을 하고 세척행정을 진행시키는 제2과정과, 상기 감지되는 수온이 설정온도에 도달되지 이전에 설정시간이 경과되면 현재감지되는 수온과 초기감지된 초기수온과의 차온도로 수온의 변화량을 판단하는 제3과정과, 상기 수온의 변화량 판단결과 수온의 변화가 없으면 가열에러로 판단하고 상기 구동시킨 세척모터 및 히터를 오프시킨 후 표시부를 통해 가열에러를 표시하고 세척행정을 종료하는 제4과정을 순차실행시켜 상기와 같은 종래 기술의 문제점을 해결하였다.Therefore, in the present invention, when the washing stroke starts, water is supplied by the set water level, the washing motor and the heater are driven, and then the first process of detecting the initial water temperature and searching for the passage of the set time, and before the set time elapses. The second process of judging normal heating when the detected water temperature reaches the set temperature and proceeding with the washing process; and if the set time has elapsed before the detected water temperature reaches the set temperature, the currently detected water temperature and initial detected initial The third process of determining the change amount of the water temperature by the difference between the water temperature and the determination result of the change amount of the water temperature, if there is no change in the water temperature is determined to be a heating error, turn off the driven cleaning motor and the heater and then the heating error through the display unit The fourth step of displaying and terminating the washing stroke was sequentially executed to solve the problems of the prior art as described above.

Claims (3)

세척행정이 시작되면 설정수위만큼 급수를 행하고, 세척모터 및 히터를 구동시킨 후 초기수온을 감지하고 설정시간의 경과유무를 검색하는 제1과정과, 상기 설정시간이 경과되기 이전에 감지되는 수온이 설정온도에 이르면 정상적인 가열로 판단을 하고 세척행정을 진행시키는 제2과정과, 상기 감지되는 수온이 설정온도에 도달되지 이전에 설정시간이 경과되면 현재감지되는 수온과 초기감지된 초기수온과의 차온도로 수온의 변화량을 판단하는 제3과정과, 상기 수온의 변화량 판단결과 수온의 변화가 없으면 가열에러로 판단하고 상기 구동시킨 세척모터 및 히터를 오프시킨 후 표시부를 통해 가열에러를 표시하고 세척행정을 종료하는 제4과정으로 이루어짐을 특징으로 하는 식기세척기의 가열에러 감지방법.When the washing stroke is started, the water supply is supplied by the set water level, the washing motor and the heater are driven, the first process of detecting the initial water temperature and searching whether the set time has elapsed, and the water temperature detected before the set time is elapsed. When the set temperature is reached, the second process of determining normal heating and proceeding with the washing process, and the difference between the currently detected water temperature and the initial detected initial water temperature when the set time elapses before the detected water temperature reaches the set temperature. The third process of determining the change amount of the water temperature by the temperature, and if there is no change in the water temperature as a result of the determination of the change amount of the water temperature is determined to be a heating error, turn off the driven washing motor and the heater and then display the heating error through the display unit and the washing administration Heating error detection method of the dishwasher, characterized in that the fourth step of terminating the process. 제1항에 있어서, 상기 제3과정은 초기수온 감지 후 설정시간의 경과여부를 검색하는 제1단계와, 상기 설정시간이 경과되면 현재감지되는 수온에서 상기 초기수온을 감산하여 차온도(A)를 산출하는 제2단계와, 상기 산출한 온도(A)와 수온의 변화를 검출하기 위해 기설정된 기준온도(ΔT)와를 비교하여 수온의 변화량을 판단하는 제3단계로 이루어짐을 특징으로 하는 식기세척기의 가열에러 감지 방법.The method of claim 1, wherein the third process comprises: a first step of searching whether the set time has elapsed after the initial water temperature is detected, and subtracting the initial water temperature from the currently detected water temperature after the set time has elapsed; And a third step of comparing the calculated temperature (A) with a predetermined reference temperature (ΔT) to determine a change amount of the water temperature in order to detect the change of the water temperature. How to detect heating error 제1항에 있어서, 상기 제4과정은 상기 차온도가 기준온도 보다 클경우 정상적인 가열에 의해 수온이 변화된 것으로 판단을 하며, 상기 차온도가 기준온도 보다 작을 경우에는 수온의 변화가 없으므로 가열에러로 판단하는 것을 특징으로 하는 식기세척기의 가열에러 감지방법.The method of claim 1, wherein the fourth process determines that the water temperature is changed by normal heating when the difference temperature is higher than the reference temperature. When the difference temperature is lower than the reference temperature, there is no change in the water temperature.
