Description
본 발명은 식기세척기의 펌프동결방지방법에 관한 것으로, 특히 동절기에 실내온도 저하로 인하여 식기세척기의 펌프에 잔수가 동결되는 것을 방지하여 식기세척시 상기 펌프의 동결로 인하여 식기세척기의 고장을 사전에 방지할 수 있도록 한 식기세척기의 펌프동결방지방법에 관한 것이다.The present invention relates to a method for preventing a pump freezing of a dishwasher, and in particular, to prevent freezing of residual water in a pump of a dishwasher due to a decrease in room temperature in winter, so that the malfunction of the dishwasher is prevented due to the freezing of the pump during dishwashing. It relates to a method for preventing the pump freezing of the dishwasher to prevent it.
일반적으로 식기세척기는 실내 주방에 설치하여 식사 완료후 오염된 식기를 깨끗하고 위생적으로 세척해 주는 기기 이다.In general, a dishwasher is a device installed in an indoor kitchen to clean and sanitarily clean contaminated tableware after a meal is completed.
그러나 상기 식기세척기는 혹한기에 장기간 외출로 인하여 집을 비워두었을때 실내온도 저하로 인하여 식기세척기의 내부가 동결되는 현상이 발생된다.However, the dishwasher may freeze inside the dishwasher due to a decrease in room temperature when the house is left vacant for a long time in a cold weather.
왜냐하면 상기 식기세척기는 식기세척 완료후 식기세척기의 내부에 구비된 펌프나 그밖에 급수구 또는 배수구에 물이 완전히 제거되지 않고 잔존하고 있기 때문에 상기와 같이 혹한기에 장기간 사용하지 않거나 실내온도가 급격히 저하 되었을 때 상기 식기세척기 내부에 잔존하는 물이 결빙되는 현상이 발생되어 결국 식기세척기의 내부 펌프, 급수구, 배수구가 동결되게 된다.Because the dishwasher does not completely remove water in the pump or other water supply or drain in the inside of the dishwasher after the dishwashing is completed, such as when not used for a long time in the cold or when the room temperature drops sharply Water remaining in the dishwasher may freeze, resulting in freezing of the internal pump, the water inlet and the drain of the dishwasher.
그러므로 상기 혹한기에 실내온도가 저하된 상태에서 사용을 하지 않을 경우 상기 식기세척기의 펌프내부에 잔수는 결빙이 되게 되어 이 결빙을 해빙 하지 않은 상태에서 바로 사용을 하게 되면 식기세척기의 펌프는 내부의 결빙 상태에 의하여 동작을 하지 않거나, 혹은 무리하게 작동을 하게 되므로 세척기에 펌프에 과부하 또는 손상을 입히게 되어 고장을 유발하게 결국 식기세척을 할 수 없는 경우가 발생된다.Therefore, if the temperature is not used in the cold season, the remaining water inside the pump of the dishwasher will be frozen. If the product is used immediately without thawing, the pump of the dishwasher will freeze. Because the operation is not performed by the state or the operation is excessive, the pump may be overloaded or damaged in the washing machine, causing a failure, and thus dishwashing may not be performed.
그럼에도 불구하고 종래 식기세척기의 경우 상기 혹한기 장기간 외출시나 실내온도의 급격한 저하되었을 때 식기세척기의 펌프내부에 발생되는 동결을 방지할 수 있는 장치가 마련되어 있지 않아 상기 식기세척기의 신뢰성을 저하시키는 문제점을 가지게 되었다.Nevertheless, the conventional dishwasher does not have a device for preventing freezing occurring in the pump of the dishwasher when the cold weather goes out for a long period of time or when the room temperature suddenly decreases, thus reducing the reliability of the dishwasher. It became.
본 발명은 식기세척기를 혹한기에 장기간 사용하지 않거나 혹은 실내온도가 급격히 저하되었을 때 펌프내부의 잔수가 동결되는 것을 방지할 수 있도록 하고자 하는데 있으며, 이를 실현하기 위하여 식기세척기의 펌프내부에 수온 센서를 장착하여 식기세척시 상기 수온센서로 펌프내부의 잔수온도를 감지하고 이 감지된 온도가 결빙온도인가를 판단하여 상기 감지된 온도가 결빙온도가 아니면 급수하면서 세척을 하고, 상기 감지된 온도가 결빙온도이면 펌프를 오프하고 급수하면서 히터를 온하여 상기 급수되는 세탁수를 가열하고, 이 가열된 세척수로 펌프를 해동한 후 세척을 하도록 한 것을 특징으로 한다.The present invention is intended to prevent the residual water inside the pump freezing when the dishwasher is not used for a long time in a cold weather or when the room temperature is sharply lowered. To realize this, a water temperature sensor is installed inside the pump of the dishwasher. When washing the dish, the water temperature sensor detects the residual water temperature inside the pump, and determines whether the detected temperature is the freezing temperature, and if the detected temperature is not the freezing temperature, washing with water and if the detected temperature is the freezing temperature. The heater is turned on while the pump is turned off and water is supplied to heat the wash water to be supplied, and the washing is performed by thawing the pump with the heated wash water.

상기와 같이 이루어지는 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention made as described above are as follows.
먼저 식기를 세척하기 위하여는 세척하고자 하는 식기를 식기세척기의 세척실(1)내에 장착되는 선반(2)에 재치하고, 이어서 세척하고자 하는 일련세척 행정신호를 운전신호입력부(가)를 통해서 마이콤(나)에 입력시키게 되면 상기 마이콤(나)에서는 상기 운전신호입력부(가)에서 입력된 일련의 세척행정에 대하여 기설정된 소정의 프로그램에 의하여 제어하고 제어된 신호를 급배수구동부(다)에 출력하여 급수를 하고, 수위감지부(라)를 통해서 급수수위를 감지하며 상기 급수가 완료되면 펌프구동부(마)를 제어하여 세척수를 펌핑하고, 분사노즐(3)를 통해서 식기에 분사하면서 식기를 세척하게 된다.First, in order to wash the dishes, the dishes to be cleaned are placed on the shelf 2 mounted in the washing room 1 of the dishwasher, and then the serial washing signal to be cleaned is transferred through the operation signal input unit A. B) If input to the microcomputer (b) is controlled by a predetermined program for the series of washing operation input from the operation signal input unit (a) by outputting the controlled signal to the water supply and drain driver (c) When the water supply is completed, the water level is sensed through the water level detection unit (D), and when the water supply is completed, the pump driving unit (E) is controlled to pump the washing water, and the dishes are washed while spraying the dishes through the injection nozzle (3). do.
이와같이 식기를 세척하는 식기세척기의 경우, 가령 동절기나 혹은 실내 온도가 급격히 저하되었을 때, 상기 식기세척기의 펌프(4)내부에 잔수는 실내 온도 저하로 인하여 결빙되는 경우가 종종 발생되게 된다.As described above, in the case of the dishwasher for washing dishes, for example, when the winter temperature or the room temperature drops sharply, the residual water inside the pump 4 of the dishwasher often freezes due to the decrease in the room temperature.
그러므로 상기와 같이 동절기나 실내온도가 급격히 저하된 상태에서 사용자는 식기를 세척하기 위하여 식기를 선반(2)에 재치하고, 이어서 식기세척기의 운전신호입력부(가)를 통해서 식기세척운전신호를 입력하게 되면, 상기 마이콤(나)에서는 기설정된 소정의 프로그램에 의하여 운전시작신호입력판단단계(30)로 가서 운전시작신호가 입력되었는가를 판단하게 된다.Therefore, when the winter or indoor temperature is rapidly lowered as described above, the user places the dish on the shelf 2 to wash the dish, and then inputs the dish washing operation signal through the operation signal input unit of the dishwasher. Then, the microcomputer (b) goes to the operation start signal input determination step 30 by a predetermined program and determines whether the operation start signal has been input.
이때 상기 운전시작신호입력판단단계(30)에서 운전신호입력부(가)로 부터 운전시작신호가 입력되지 않게 되면 대기상태를 유지하게 되고, 반면에 상기 운전시작신호가 입력되게 되면, 상기 마이콤(나)에서는 실내온도 저하로 인하여 펌프(4)의 내부잔수가 결빙되었는가를 판단하기 위하여 잔수온도감지단계(31)로 가서 수온감지부(사)를 제어하여 펌프(4)의 내부에 장착되어 있는 수온센서(6)로 세척완료후 펌프(4)의 내부에 잔존하게 되는 잔수온도를 감지하게 된다.At this time, when the operation start signal is not input from the operation signal input unit in the operation start signal input determination step 30, the standby state is maintained. On the other hand, when the operation start signal is input, the microcomputer (b) ), Go to the residual water temperature sensing step (31) to control the water temperature sensing unit (g) in order to determine whether the internal residual of the pump (4) is frozen due to a decrease in room temperature, the water temperature mounted inside the pump (4) The sensor 6 detects the residual water temperature remaining in the pump 4 after the cleaning is completed.
이와같이 잔수온도를 감지하게 되면 상기 마이콤(나)에서는 결빙온도판단단계(32)로 가서 상기 감지된 잔수온도가 결빙온도인가를 판단하게 되고, 이때 판단결과 잔수온도가 결빙온도가 아니면 상기 마이콤(나)에서 급수단계(33)로 가서 급배수구동부(33)를 제어하여 세척하고자 하는 수위로 세척수를 급수하되, 급수되는 수위를 수위감지부(라)를 통해서 수위센서(7)로 감지하면서 급수하고 급수가 완료되면 세척단계(34)로 가서 펌프구동부(마)를 제어하여 펌프(4)를 구동시켜면서 분사노즐(3)을 통해서 식기에 세척수를 분사하면서 식기세척을 하게 되지만, 상기 결빙온도판단단계(32)에서상기 감지된 잔수온도가 결빙온도이면, 상기 마이콤(나)에서는 펌프정지단계(35)로 가서 펌프구동부(마)를 제어하여 펌프(4)의 정지시켜놓고, 급수단계(36)로 가서 급배수구동부(다)를 제어하여 세척수를 급수하과 아울러, 세척수가열단계(37)로 가서 히터구동부(바)를 제어하여 히터(5)를 온시켜 상기 급수되는 세척수를 히터열로 가열하여 이 가열되는 세척수로 상기 펌프(4)의 내부에 결빙된 잔수를 해빙시켜 주게 된다.When the residual water temperature is detected as described above, the microcomputer (b) goes to the determination of the freezing temperature step 32 and determines whether the detected residual temperature is the freezing temperature. At this time, if the residual temperature is not the freezing temperature, the microcomputer (b) Go to the water supply step 33 to control the water supply and drainage drive 33 to supply the washing water to the water level to be washed, while the water level is detected by the water level sensor (7) through the water level sensor (D) When the water supply is completed, go to the washing step (34) to control the pump driving unit (e) to drive the pump 4 while washing the dish while spraying the washing water to the dish through the spray nozzle (3), but the determination of the freezing temperature If the detected residual water temperature in the step 32 is the freezing temperature, the microcomputer (b) goes to the pump stop step (35) to control the pump driving part (e) to stop the pump (4), the water supply step (36) Go to) The washing water is heated by controlling the driving unit (c), and the washing water is heated to the washing water heating step 37 and the heater driving unit (bar) is turned on to turn on the heater 5 to heat the washing water being heated by the heater heat. As a result, the remaining water frozen in the pump 4 is thawed.
이와같이 상기 가열되는 세척수로 상기 결빙된 펌프(4)의 잔수를 해방시키고 있는 상태에서 상기 마이콤(나)에서는 상기 잔수온도감지단계(31)로 가서 상기 수온감지부(사)를 제어하여 수온센서(6)로 해빙되는 펌프(4)의 잔수온도를 감지하고 상기 결빙온도판단단계(32)로 가서 상기 감지된 잔수온도가 결빙온도인가를 판단하게 되고, 이때 판단결과 잔수온도가 아직도 결빙온도이면, 상기 결빙온도판단단계(32)에서 상기 감지된 잔수온도가 결빙온도이면, 상기 마이콤(나)에서는 펌프정지단계(35)로 가서 펌프(4)의 정지시키고, 급수단계(36)로 가서 급수함과 아울러 세척수가열단계(37)로 가서 히터(5)를 온시켜 상기 급수되는 세척수를 히터열로 가열하면서 상기 펌프(4)의 내부에 결빙된 잔수를 해빙될 때 까지 반복수행하게 되고, 반면에 상기 감지된 온도가 결빙온도가 아니면 상기 마이콤(나)에서는 펌프(4)의 잔수가 해빙된 것으로 판단하여 급수단계(33)로 가서 급배수구동부(33)를 제어하여 세척하고자 하는 수위로 세척수를 급수하고, 수위감지부(라)를 통해서 감지하면서 급수가 완료될 때까지 급수하고 세척단계(34)로 가서 펌프구동부(마)를 제어하여 펌프(4)를 구동시키면서 분사노즐(3)을 통해서 식기에 세척수를 분사하면서 식기세척을 하게 되는 것이다.As described above, the microcomputer (b) goes to the residual water temperature sensing step 31 and controls the water temperature sensing part 4 in the state of releasing the residual water of the frozen pump 4 with the heated washing water. 6) detects the residual water temperature of the pump (4) to be thawed, and go to the determination step of determining the freezing temperature (32) to determine whether the detected residual water temperature is the freezing temperature, wherein if the residual temperature is still the freezing temperature, If the detected residual water temperature in the freezing temperature determination step 32 is the freezing temperature, the microcomputer (b) goes to the pump stop step 35 and stops the pump 4, and goes to the water supply step 36 to supply water. In addition, the washing water is heated to the heating step 37 and the heater 5 is turned on, and the washing water being heated is heated by the heater heat and repeatedly performed until the frozen water remaining in the pump 4 is thawed. The detected temperature If it is not the freezing temperature, the microcomputer (b) determines that the residual water of the pump 4 has thawed, and goes to the water supply step 33 to control the water supply and drainage drive unit 33 to supply the washing water to the level to be washed, and to detect the water level. The water is injected through the spraying unit (D), and the washing water is sprayed to the dish through the spray nozzle 3 while driving the pump 4 by controlling the pump driving unit (e) to go to the washing step 34.
