본 발명은 식기세척기의 세척조내 증기압 배출방법에 관한 것으로 더자세히는, 식기세척기의 노즐에 의해 분사되는 물로 인한 압력이 세척조 외부로 배출되는 시간을 둔 식기세척기의 세척조내 증기압 배출방법에 관한 것이다. 종래의 경우, 식기세척기에 세척수를 공급하고 적정수위가 되면, 펌프모터를 동작시켜 세척을 진행하게 되는데, 세척펌프 동작시 노즐을 통해 분사되는 세척수 특히 온수의 압력(증기압)이 세척조 외부로 배출되지 못하는 경우가 빈번하여, 세척탱크가 압력을 받고, 도어가 오프되어, 세척조 외부로 세척수가 튀어나가는 등 여러 문제점이 뒤따랐다. 또한, 급수를 제어하는 압력스위치에 세척이 진행되면서 압력이 전달되어 압력스위치를 동작시켜 이상수위 압력스위치가 오동작되는 문제가 있었고, 압력배기가 원활히 진행되지 않아, 도어의 전면부로 물이 넘쳐 튀어나오는등 실링(Sealing)에 많은 문제가 유발되었다. 이에 본 발명은 상술한 바와같은 종래의 제반 문제점을 감안하여 안출된 것으로, 식기세척기의 세척시 동작하는 펌프모터를 주기적으로 ON/OFF시킴으로써 내부의 증기압을 배출시키도록된 식기세척기의 세척조내 증기압 배출방법을 제공함에 그 목적이 있는 것이다. 이하 첨부된 도면을 참조하여 구성 및 작용효과를 상세히 설명하면 다음과 같다.The present invention relates to a method for discharging the steam pressure in the washing tank of the dishwasher, and more particularly, to a method for discharging the steam pressure in the washing tank of the dishwasher with a time for discharging the pressure caused by the water injected by the nozzle of the dishwasher to the outside of the washing tank. In the conventional case, when the washing water is supplied to the dishwasher and the proper water level is reached, the pump motor is operated to perform the washing. When the washing pump is operated, the pressure (steam pressure) of the washing water sprayed through the nozzle is not discharged to the outside of the washing tank. In many cases, the cleaning tank is pressured, the door is turned off, and the washing water splashes out of the washing tank. In addition, there is a problem that the abnormal water level pressure switch malfunctions by operating the pressure switch as the pressure is transferred to the pressure switch to control the water supply, and the pressure exhaust does not proceed smoothly, water overflows to the front of the door Many problems have arisen in back sealing. Accordingly, the present invention has been made in view of the above-described conventional problems, and the steam pressure discharge in the washing tank of the dish washer to discharge the internal steam pressure by periodically turning on / off the pump motor operated during the washing of the dishwasher. The purpose is to provide a method. Hereinafter, with reference to the accompanying drawings, the configuration and operation effects will be described in detail.

본 발명의 목적을 달성하기 위하여, 냉,온수를 공급하여 분사노즐(4)을 통해 세척을 진행하는 식기세척기(1)에 있어서, 세척조(2)로 공급되는 세척수 온도에 따라 온도감지센서(5)에서 세척수 온도를 감지하고, 온도감지센서(5)의 감지신호에 따라 마이컴에서, 세척펌프(3)의 구동모터를 주기적으로 ON/OFF하여 세척을 진행함으로써 세척시 발생되는 증기압이 증기배출구(6)로 원활히 배출되는 시간을 두어 세척을 수행토록 구성된 것으로, 미 설명부호 7은 급수밸브인 것이다. 이상과 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.In order to achieve the object of the present invention, in the dishwasher (1) for supplying cold and hot water to perform the washing through the spray nozzle (4), the temperature sensor (5) according to the washing water temperature supplied to the washing tank (2) The steam pressure generated by washing is sensed by washing water temperature and cleaning is performed by periodically turning on / off the driving motor of the washing pump 3 in the microcomputer according to the detection signal of the temperature sensor 5. 6) It is configured to perform the cleaning by allowing a smooth discharge time, and the reference numeral 7 is a water supply valve. Referring to the effects of the present invention configured as described above are as follows.

도면 제2도에서 보는 바와같이 식기세척기의 전원을 인가하게되면 급수밸브(7)를 통해 세척조(2)내로 세척수가 공급되면서, 온도감지센서(5)에서 세척수의 온도를 감지하게 된다. 이때 세척수가 일정온도 이상이면 온도감지센서(5)를 통해 마이컴에서 인식하게 되고, 종래에는 다음표와 같이 (급수세척)구동되었으나, 본 발명은 펌프모터의 구동을 일정시간을 주기로 (급수세척)와같이 ON/OFF하여, 증기압을 단계적으로 배출토록하는 시간을 두어 효과적인 세척기능을 수행토록 된것이다.When the power of the dishwasher is applied as shown in FIG. At this time, if the washing water is above a certain temperature, it is recognized by the microcomputer through the temperature sensor 5, and conventionally, as shown in the following table (water washing ), But the present invention is to drive the pump motor at regular intervals (water cleaning By turning on / off as shown in Fig. 2), it is possible to perform effective cleaning function by allowing time to discharge steam pressure step by step.

이상에서 본 바와같이 본 발명은 세척펌프(3)-모터에 의해 세척수를 분사노즐(4)로 뿜어대면 증기배출구(6)로 증기가 빠져나가게되고, 세척펌프-모터가 계속 구동함에 따라 미처 빠져 나가지 못한 증기가 누적됨으로 인해 세척조(2)내의 증기압이 발생되는 종래기술의 문제점을 탈피하여, 세척펌프(3)-모터의 구동을 제어하여 단계적으로 세척조(2) 내부의 증기를 배출시키고, 급수되는 수온에 따라 온도감지센서(5)가 감지하여 세척펌프(3)-모터 구동을 제어하며 세척을 진행토록된 발명인 것이다.As described above, in the present invention, when the washing water is sprayed by the washing pump (3) -motor to the injection nozzle (4), steam is discharged to the steam outlet (6), and the washing pump-motor keeps running out as it continues to run. Avoiding the problem of the prior art in which the steam pressure in the washing tank 2 is generated due to the accumulation of steam that has not exited, controlling the driving of the washing pump 3-the motor to discharge the steam inside the washing tank 2 step by step, and According to the water temperature to be detected by the temperature sensor (5) to control the washing pump (3) -motor drive and to proceed with the washing.
