식기세척기의 증기배출구 개폐장치Steam outlet switchgear of dishwasher

본 발명은 식기세척기의 증기배출구 개페장치에 관한 것으로 특히 세정수를 이용하여 증기배출구의 개폐를 가능하게 하여 소음을 저감함으로 소비자로 하여금 제품의 신뢰성을 높힐수 있도록한 것이다.The present invention relates to a steam outlet opening device of the dishwasher, in particular to enable the opening and closing of the steam outlet by using the washing water to reduce the noise to enable consumers to increase the reliability of the product.

종래 식기세척기의 증기배출구는 도1과 같이 정면의 도어(1)부분에 증기가 배출되는 증기배출구(2)를 형성하고, 상기 증기배출구(2)내에 형성된 하우징(3)내에는 세정조(4)내의 증기를 흡입하여 배출할 수 있도록 모터(5)에 의하여 구동되는 팬(6)과, 상기 팬(6)의 구동에 의하여 세정조(4)내의 증기가 하우징(3)로 흡입되도록 내벽(7)에 증기흡입구(8)가 구성되였다.The steam outlet of the conventional dishwasher forms a steam outlet 2 through which steam is discharged in the front door 1 portion as shown in FIG. 1, and the cleaning tank 4 is formed in the housing 3 formed in the steam outlet 2. Fan 6 driven by the motor 5 to suck and discharge steam in the inner wall, and an inner wall to suck steam in the cleaning tank 4 into the housing 3 by driving the fan 6. A steam inlet 8 is constructed at 7).

이와같이 구성된 식기세척기의 작동을 설명하면 다음과 같다.Referring to the operation of the dishwasher configured in this way as follows.

식기의 세척을 완료한 후에는 식기를 건조하기 위하여 세정조(4)내에서 발생된 증기를 배출하여야 하는데, 이때는 모터(5)를 구동시키면 팬(6)이 회전하기 때문에 세정조(4)내의 증기가 흡입구(8)와 하우징(3)을 통하여 증기배출구(2)로 이어지는 증기유로를 통하여 토출된다.After the washing of the dishes is completed, the steam generated in the washing tank 4 should be discharged to dry the dishes. In this case, when the motor 5 is driven, the fan 6 rotates, so Steam is discharged through the steam passage leading to the steam outlet 2 through the inlet 8 and the housing 3.

그러나, 식기를 세척하기 위하여 식기세척기를 가동시키면 수류에 의한 충격음 및 낙수에 의한 하부 물표면과의 충돌로 내부에서 매우 높은 레벨의 소음이 발생하였다.However, when the dishwasher was operated to wash the dishes, a very high level of noise was generated in the interior due to impact sound caused by water flow and collision with the lower water surface caused by falling water.

이와같이 발생된 소음은 흡입구(8)와 증기배출구(2)를 통하여 외부로 유출되기 때문에 세척기의 주요 소음 원인이 되는 문제점이 발생하였다.Since the noise generated as described above flows out through the inlet 8 and the steam outlet 2, a problem that causes the main noise of the cleaner occurs.

이러한 점을 감안하여 소음을 줄이기 위하여 세척시에 증기유로를 닫을 수 있는 개폐장치를 설치하려면 그에 따른 구동부의 추가와 더불어 구조가 복잡해지기 때문에 원가상승 및 고온, 다습의 조건에서 작동가능토록 하기 위한 신뢰성등이 요구되는 문제점이 발생하였다.In view of this, it is necessary to install the switchgear that can close the steam flow when cleaning to reduce the noise. Therefore, the structure is complicated with the addition of the driving part. Therefore, it is reliable to be able to operate in the condition of high cost and high temperature and high humidity. Problems such as the need arise.

본 발명은 이러한 점을 감안하여 발명한 것으로서 세정조의 내벽에 형성된 흡입구의 앞에 차음판을 형성하고, 상기 차음판의 하단은 흘러내려 저수조에 모아진 세정수에 잠기게 함으로서 식기세척시 발생되는 소음이 증기배출구를 통하여 유출되는 것을 방지하여 주기 때문에 소음을 저감시켜줌과 더불어 제품의 신뢰성을 향상시키는데 목적이 있다.The present invention has been invented in view of this point, and the sound insulation plate is formed in front of the suction port formed in the inner wall of the cleaning tank, and the lower end of the sound insulation plate flows down so as to be immersed in the washing water collected in the storage tank so that the noise generated during dish washing is steam. Because it prevents outflow through the outlet, it aims to reduce noise and improve the reliability of the product.

본 발명 식기세척기의 증기배출구 개폐장치를 도2 및 도3에 의하여 상세히 설명하면 다음과 같다.The steam outlet opening and closing device of the present invention will be described in detail with reference to Figures 2 and 3 as follows.

정면의 도어(101)부분에 증기가 배출되는 증기배출구(102)를 형성하고, 상기 증기배출구(102)내에 형성된 하우징(103)내에는 세정조(104)내의 증기를 흡입하여 배출할 수 있도록 모터(105)에 의하여 구동되는 팬(106)과, 상기 팬(106)의 구동에 의하여 세정조(104)내의 증기가 하우징(103)로 흡입되도록 내벽(107)에 증기흡입구(108)가 구성된 것에 있어서,A steam outlet 102 is formed at the front door 101 to discharge steam, and the motor 103 can suck and discharge steam in the cleaning tank 104 in the housing 103 formed in the steam outlet 102. The steam inlet 108 is formed in the inner wall 107 such that the fan 106 driven by the 105 and the steam in the cleaning tank 104 are sucked into the housing 103 by the driving of the fan 106. In

세정조(104)에서 식기를 세척시 발생되는 소음이 내벽에 형성된 흡입구(108)를 통하여 증기가 배출되는 증기배출구(102)로 유출되는 것을 방지하는 차음판(109)과, 상기 차음판(109)을 따라 흘러내려 모아진 세정수에 의하여 차음판(109)의 하단이 잠겨지도록 형성된 저수조(110)와, 상기 저수조(110)에는 모아지는 세정수가 배수되는 배수구(111)를 구비하였다.A sound insulation plate 109 for preventing the noise generated when washing dishes in the cleaning tank 104 to the steam outlet 102 through which the steam is discharged through the inlet 108 formed on the inner wall, and the sound insulation plate 109. Water reservoir 110 is formed so that the lower end of the sound insulating plate 109 is locked by the washing water collected by flowing along the), and the water reservoir 110 has a drain 111 for draining the washing water collected.

그리고, 상기 배수구(112)는 단위 시간당 세정수의 배수량이 저수조(110)로 세정수가 유입되는 단위 시간당 유입량 보다 작게 구비하였다.In addition, the drain 112 has a smaller drainage amount of washing water per unit time than the amount of inflow of washing water into the reservoir 110.

이와같이 구성된 상태에서 세척기를 가동시키면 분사노즐로 부터 분사되는 세정수에 의하여 세척이 진행되고, 또한 세정수가 펌프에 의해 계속 순환하여 세정조내에 있는 식기를 세척한다.When the washing machine is operated in this configuration, washing is performed by the washing water sprayed from the spray nozzle, and the washing water is continuously circulated by the pump to wash the dishes in the washing tank.

이때, 분사노즐에 의해 분사되는 세정수의 많은 양이 세정조(104)의 벽면을 타고 흘러내린다.At this time, a large amount of the washing water sprayed by the spray nozzle flows down the wall surface of the washing tank 104.

이와같이 흘러내리는 세정수의 일부는 차음판(109)을 따라 흘러내려 저수조(110)에 모아질 뿐만아니라, 세척되는 식기 및 벽면등으로 부터 반사되어진 세정수 등이 유입되어 고이게 된다.Part of the washing water flowing down in this way flows down along the sound insulation plate 109 and is collected in the water tank 110, and the washing water reflected from the dishes and walls to be washed is introduced therein.

이와같이 저수조(110)에 모여지는 세척수는 저수조(110)에 단위 시간당 유입되는 세정수의 양이 배수구(111)로 배수되는 양보다 적기 때문에 저수조(110)에 세정수가 모여지게 된다.As such, the washing water gathered in the reservoir 110 is collected in the reservoir 110 because the amount of washing water introduced into the reservoir 110 per unit time is less than the amount drained into the drain 111.

따라서, 모아지는 세정수에 차음판(109)을 하단이 묻힘으로 인하여 식기를 세척하는 과정에서 발생된 소음이 흡입구(108)와 증기배출구(102)를 통하여 외부로 유출되는 것을 방지할 수 있는 것이다.Therefore, the noise generated in the process of washing the dishes due to the bottom of the sound insulating plate 109 is buried in the collected water can be prevented from leaking to the outside through the inlet 108 and the steam outlet 102. .

이와같이 저수조(110)로 유입되는 세정수의 단위 시간당 유입량을 Q1(리터/초)이라 하고, 배수구(111)로 배출되는 단위 시간당 배수량을 Q2(리터/초)라 하며, 저수조(110)의 입구까지 채워지는데 이의 유량은 Q0라 한다.In this way, the inflow rate of the washing water flowing into the reservoir 110 is called Q1 (liters / second), and the discharge amount per unit time discharged to the drain 111 is called Q2 (liters / second), and the inlet of the reservoir 110 is provided. The flow rate is called Q0.

이때, 배수구(111)의 크기가 Q1 Q2로 되었기 때문에 Q3 = Q1 - Q2(리터/초)의 세정수가 저수조(110)의 외부로 넘쳐 배출되며, 일단 저수조(110)에 세정수가 찬 후에는 Q1 Q2이기 때문에 항상 저수조(110)에는 세정수가 넘쳐 흐르게 된다.At this time, since the size of the drain 111 is Q1 Q2, the washing water of Q3 = Q1-Q2 (liters / sec) overflows to the outside of the reservoir 110, and once the washing water is filled in the reservoir 110, Q1. Since it is Q2, the washing tank 110 always overflows the washing water.

그리고, 유입된 세정수량 Q1은 배수구(111)으로 Q2의 양이 배출되고 저수조(110)입구에서 넘치게 되어 Q3 = Q1 -Q2의 양이 세정조 내부로 넘치게 된다.In addition, the amount of water Q1 introduced is discharged to the drain 111 and the amount of Q2 is discharged and overflowed at the inlet of the reservoir 110 so that the amount of Q3 = Q1 -Q2 is overflowed into the cleaning tank.

따라서, 세척 시작후 시간 T1 = Q0 / (Q1-Q2)= Q0/Q3(초)의 시간이 지나면 차음판(109)과 세정수에 의하여 증기유로는 완전히 차단이 되며, 증기유로를 통하여 외부로 방사되는 소음 레벨이 현저히 저하된다.Therefore, after the time T1 = Q0 / (Q1-Q2) = Q0 / Q3 (seconds) after the start of washing, the steam flow path is completely blocked by the sound insulation plate 109 and the washing water, and the outside flows through the steam flow path. The noise level emitted is significantly reduced.

한편, 세척이 종료되면 저수조(110)로 유입되는 유량 Q1이 없으므로 저수조(110)애 남아있는 유량 Q0만이 배수구(111)를 통하여 시간 T2 = Q0/Q2(초)후에 완전히 배출되어지므로 팬(106)의 구동을 통한 증기배출 과정이 이뤄지게 된다.On the other hand, when the washing is finished, there is no flow rate Q1 flowing into the reservoir 110, so only the flow rate Q0 remaining in the reservoir 110 is completely discharged after the time T2 = Q0 / Q2 (seconds) through the drain 111. The steam discharge process is performed by driving).

상기 시간 T2(초)는 세척완료후에 세정수 배수시간에 비해 매우 짧은 시간이므로 이로 인한 시간 지연은 발생하지 않게된다.Since the time T2 (second) is a very short time compared to the washing water drainage time after the washing is completed, there is no time delay.

이와같은 본 발명은 식기세척시 발생되는 소음이 증기배출구로 유출되는 것을 방지할수 있고, 또한 증기배출구로 소음이 유출되는 것을 방지하기위한 개폐장치의 구조가 단순한 구조로 이루어질수 있으며, 소음이 유출되는 것을 방지하는 개폐장치로 인한 제품의 신뢰성이 확보되는 발명이다.The present invention as described above can prevent the noise generated during dish washing to flow out of the steam outlet, and the structure of the switchgear for preventing the leakage of noise into the steam outlet can be made of a simple structure, that the noise is leaked The invention is to ensure the reliability of the product due to the switchgear to prevent.
