Description

식기세척기{DISHES WASHING MACHINE}Dishwasher {DISHES WASHING MACHINE}

본 발명은 식기 세척시에 발생된 찌꺼기가 노즐을 통해 다시 분사되어 세척된 식기가 재오염 되는 것을 방지함과 동시에 포집된 찌꺼기를 배수시 전부 외부로 배출시킬 수 있도록 하는 식기 세척기에 관한 것이다.The present invention relates to a dish washer that prevents re-contamination of the washed dishes by spraying again the debris generated during dish washing through the nozzle and simultaneously discharging the collected debris to the outside during drainage.

종래 식기 세척기의 구성은 도 1에 도시된 바와 같이 선반(1)에 수납된 식기(11)에 세척수를 분사하는 노즐(2)과;The conventional dishwasher includes a nozzle 2 for spraying the washing water onto the dishware 11 stored in the shelf 1 as shown in FIG. 1;

상기 노즐(2)과 토출관(32)으로 연결하여 세척수를 공급하는 세척펌프(3)와;A washing pump 3 connected to the nozzle 2 and the discharge pipe 32 to supply washing water;

상기 세척펌프(3)에 흡입관(31)으로 연결하여, 노즐(2)에서 분사된 세척수가 세척조(6)를 통해 그 내부에 떨어져서 모이며, 그 상부에 제 1 필터(41)가 구비된 집수조(4)와;Connected to the washing pump (3) by the suction pipe (31), the washing water sprayed from the nozzle (2) is collected by falling into the interior through the washing tank (6), the water collecting tank having a first filter (41) at the top (4);

상기 식기의 세척이 완료된 후 세척수 및 찌꺼기를 외부에 배출시키는 배수호스(51)가 구비된 배수펌프(5)로 이루어진다.After the washing of the dishes is completed is composed of a drain pump 5 is provided with a drain hose 51 for discharging the washing water and the residue to the outside.

그리고, 상기 토출관(32)의 일측에는 분기관(33)이 결합되고, 상기 분기관(33)의 끝단에는 상부에 제2필터(71)가 구비된 포집실(7)이 연결설치되며, 상기 포집실(7)의 일측에는 배출관(42)이 설치된다.A branch pipe 33 is coupled to one side of the discharge pipe 32, and a collecting chamber 7 having a second filter 71 at an upper end thereof is connected to an end of the branch pipe 33. One side of the collecting chamber 7 is provided with a discharge pipe 42.

상기와 같이 이루어진 식기 세척기의 세척과정을 설명하면 다음과 같다.Referring to the washing process of the dishwasher made as described above are as follows.

먼저, 선반(1)에 세척하고자 하는 식기(11)를 수납한 후 전원스위치를 누르게 되면, 급수가 시작되며 정해진 사이클에 의해 세척행정이 진행된다.First, after storing the tableware 11 to be washed on the shelf 1 and pressing the power switch, the water supply starts and the washing administration proceeds by a predetermined cycle.

이때, 상기 세척행정을 세척펌프(3)가 가동을 시작하면 토출관(32)을 통해 노즐(2)에 세척수를 공급하게 되고, 상기 노즐(2)에서 분사된 세척수는 식기(11)와 부딪히며 식기(11)에 묻어 있는 찌꺼기를 제거하게 된다.At this time, when the washing pump 3 starts operating the washing stroke, the washing water is supplied to the nozzle 2 through the discharge pipe 32, and the washing water sprayed from the nozzle 2 collides with the dishware 11. The residue on the tableware 11 is removed.

상기 찌꺼기와 세척수는 함께 세척조(6)에 떨어져 집수조(4)에 모이게 된다. 이때 상기 찌꺼기들은 제 1 필터(41)에 의해 걸러져 제 1 필터(41)의 직하부에 모이게 된다. 또한, 집수조(4)에 모인 세척수는 흡입관(31)을 통하여 세척펌프(3)에 공급된다.The debris and washing water fall together in the washing tank 6 and are collected in the sump tank 4. In this case, the debris is collected by the first filter 41 and collected directly under the first filter 41. In addition, the washing water collected in the sump (4) is supplied to the washing pump (3) through the suction pipe (31).

그리고, 상기 세척펌프(3)에 공급되어 토출관(32)으로 재배출되는 세척수에는 미세한 찌꺼기들이 섞여있는 바, 상기 미세한 찌꺼기들이 노즐(2)을 통해 분사되어 다시 식기(11)에 묻게 되면 세척효율이 떨어지게 됨은 물론이다.In addition, the fine water is mixed in the washing water supplied to the washing pump 3 and re-extracted to the discharge pipe 32. When the fine waste is sprayed through the nozzle 2 and buried in the dish 11 again, the washing water is washed. Of course, the efficiency is reduced.

따라서, 이를 방지하기 위해 제 2 필터(71)가 구비된 포집실(7)과 토출관(32)의 입구 사이에 분기관(33)을 설치 연결하여 세척펌프(3)에서 토출되는 세척수중 일부를 분기관(33)으로 분기 토출시켜 포집실(7)의 제 2 필터(71)를 통과하게 함으로서, 세척수중의 찌꺼기가 걸러지게 하여 떨어진 세척효율을 높이게 한다.Therefore, in order to prevent this, a part of the washing water discharged from the washing pump 3 by installing and connecting the branch pipe 33 between the collection chamber 7 provided with the second filter 71 and the inlet of the discharge pipe 32. Branched discharge to the branch pipe (33) to pass through the second filter 71 of the collecting chamber (7), to filter out the debris in the washing water to increase the washing efficiency.

그러나, 상기 제 2 필터(71)에 의해 걸러진 찌꺼기들은 포집실(7)의 일측에 설치된 배출관(42)으로 떨어지게 된다. 이때 상기 제 1 필터(41)의 직하부와 배출관(42)의 끝단부가 일치되어 있으므로 제 1 필터(41)와 제 2 필터(71)에서 걸러진 찌꺼기들이 한 곳에 모이게 된다.However, the debris filtered by the second filter 71 falls into the discharge pipe 42 installed at one side of the collecting chamber 7. At this time, since the lower part of the first filter 41 and the end of the discharge pipe 42 coincide with each other, the debris filtered by the first filter 41 and the second filter 71 are collected in one place.

다음, 상기 식기(11)를 세척하는 행정이 완료되면 배수펌프(5)가 가동을 시작하며 세척수와 찌꺼기를 배수호스(51)를 통하여 외부에 배출시키게 된다.그러나, 상기 식기(11)를 세척할 때에는 세척펌프(3)는 가동을 계속하게 되고, 이로 인하여 흡입관(31)으로 세척수는 계속 공급되므로 흡입관(31)의 입구 주위에는 큰 소용돌이가 발생하게 된다.Next, when the process of washing the dish 11 is completed, the drain pump 5 starts to operate and discharges the washing water and the dregs to the outside through the drain hose 51. However, the dish 11 is washed. When the washing pump 3 continues to operate, because of this, the washing water is continuously supplied to the suction pipe 31, so that a large vortex occurs around the inlet of the suction pipe 31.

그리고, 상기 소용돌이로 인하여 제1필터(41)의 직하부와 배출관(42)의 끝단부에 모여있는 찌꺼기는 분산되어 사방으로 누설되고, 이로인하여 세척펌프(3)에 공급되는 세척수에 많은 양의 찌꺼기가 포함되어 노즐에서 분사되므로, 세척된 식기가 재 오염되는 문제점이 발생하게 된다.And, due to the vortex, the residue gathered immediately below the first filter 41 and the distal end of the discharge pipe 42 is dispersed and leaked in all directions, thereby causing a large amount of washing water to be supplied to the washing pump 3. Since the residue is included and sprayed from the nozzle, the problem is that the washed dishes are recontaminated.

또한, 상기 식기(11)에 다시 찌꺼기가 묻게 됨으로서, 세척 효율이 떨어지게 되고, 식기를 세척한 후 세척수를 외부에 배출시 세척수에 포함된 찌꺼기가 완벽하게 배출되지 못하므로 다음 가동중에 재비산되는 문제점도 발생된다.In addition, the residue is again buried in the dish 11, the washing efficiency is reduced, when the washing water is discharged to the outside after washing the dish is not completely discharged in the next operation because the waste contained in the wash water is not scattered again Is also generated.

상기와 같은 문제점등을 해결 보완하기 위하여 본 발명은,The present invention to solve the above problems and the like,

식기세척시에 발생된 찌꺼기를 포집하여 배수시 전부 외부에 배출시킬 수 있도록 하는 식기세척기를 구현함에 그 목적이 있다.An object of the present invention is to implement a dishwasher that collects the debris generated during dishwashing and discharges them to the outside during drainage.

상기의 목적을 달성하기 위하여 본 발명은,In order to achieve the above object, the present invention,

분기관과 배출관 및 포집실의 연결부위에 수로선택수단을 설치하여 세척시 발생된 찌꺼기를 포집하고 배수시 전부 배출시킴으로서, 집수조에서 분산된 찌꺼기가 세척펌프에 공급되고 다시 노즐에 의해 분사되어 세척된 식기를 재오염시키는 것을 방지함과 동시에 세척효율을 향상시킬 수 있도록 하였다.By installing the channel selection means at the connection part of the branch pipe, the discharge pipe, and the collecting chamber, it collects the debris generated during washing and discharges all the water during the drainage. Preventing re-contamination of dishes and improving the cleaning efficiency.

본 발명 식기세척기의 구성은 종래와 동일하나, 분기관(33)과 배출관(42) 및 포집실(7)의 연결부위에 수로선택수단(8)을 설치한 것이 본 발명의 특징이다.The structure of the dishwasher of the present invention is the same as that of the related art, but it is a feature of the present invention that the channel selecting means 8 is provided at the connection portion between the branch pipe 33, the discharge pipe 42 and the collecting chamber 7.

이때, 상기 수로선택수단(8)은 지지부재(82)에 의해 작동구간이 형성되며, 상기 작동구간에서 세척수의 흐름에 따라 수로를 선택하는 선택부재(81)로 이루어진다.At this time, the channel selection means 8 is formed by the support member 82, the operation section is formed, and consists of a selection member 81 for selecting the channel in accordance with the flow of the washing water in the operation section.

이에 도2와 도3 및 도4를 참조하여 더욱 상세히 설명하면, 먼저 식기세척기의 세척행정은 주지와 같으나, 상기 포집실(7)에서 포집된 찌꺼기들이 종래에는 배출관(42)을 따라 이동되었으나, 본 발명에서는 포집실(7)의 포집면(72)에 모여있게 된다.2, 3, and 4, the washing stroke of the dishwasher is first known as well, but the debris collected in the collecting chamber 7 is conventionally moved along the discharge pipe 42. In this invention, it collects in the collection surface 72 of the collection chamber 7.

즉, 도 2와 도 3에서와 같이 세척펌프93)에서 토출관(32)으로 배출되는 세척수중 일부는 분기관(33)을 따라 흐르게 되고, 상기 세척수의 흐름에 의해 선택부재(81)는 상승하여 배출관(42)의 입구를 막게 된다.That is, as shown in FIGS. 2 and 3, some of the washing water discharged from the washing pump 93 to the discharge pipe 32 flows along the branch pipe 33, and the selection member 81 is raised by the flow of the washing water. By blocking the inlet of the discharge pipe (42).

그리고, 상기 분기관(33)으로 유입된 세척수는 포집실(7)의 제2필터(71)를 통과하며 찌꺼기들이 걸러지게 되고, 상기 제2필터(71)를 통과한 세척수는 세척조(6)에 떨어져 집수조(4)에 모이게 된다.In addition, the washing water introduced into the branch pipe 33 passes through the second filter 71 of the collecting chamber 7, and the debris is filtered. The washing water passing through the second filter 71 is the washing tank 6. Fall into the sump (4).

또한, 상기와 같이 제2필터(71)에 의해 걸러진 찌꺼기들은 세척수의 흐름에 의해 다시 분기관(33)으로 돌아갈 수 없을 뿐 아니라 포집실(7) 밖으로 분산되려 하여도 제2필터(71)에 의해 통과하지 못하게 됨으로서, 포집면(72)에 모여있게 되는 것이다.In addition, as described above, the residues filtered by the second filter 71 are not only able to return to the branch pipe 33 again by the flow of the washing water, but also to be dispersed outside the collection chamber 7 to the second filter 71. By not being able to pass by, it will be gathered on the collecting surface 72.

그리고, 도 2와 도 4에서와 같이 상기 식기(11)를 세척하는 행정이 완료되면 세척펌프(3)가 가동을 정지하고 배수펌프(5)가 가동을 시작하게 되는 바, 이때에는 상기 선택부재(81)를 상부로 밀었던 분기관(33) 내의 세척수의 흐름이 상실되므로 선택부재(81)는 자중에 의해 하측으로 떨어져 지지부재(82)에 걸리게 된다. 이로 인하여 선택부재(81)에 의하여 막혔던 배출관(42)의 입구가 개방된다.Then, as shown in FIGS. 2 and 4, when the process of washing the dish 11 is completed, the washing pump 3 stops operation and the drainage pump 5 starts operation. In this case, the selection member Since the flow of the washing water in the branch pipe 33 that pushed the upper portion 81 is lost, the selection member 81 falls to the lower side by its own weight and is caught by the supporting member 82. As a result, the inlet of the discharge pipe 42 blocked by the selection member 81 is opened.

이때, 상기 선택부재(81)는 분기관(33)을 통과하는 세척수의 흐름에 따라서만 작동구간을 유동할 수 있도록 세척수보다 비중이 높아야 한다.In this case, the selection member 81 should have a higher specific gravity than the washing water so that the operation section can flow only according to the flow of the washing water passing through the branch pipe 33.

즉, 상기 선택부재(81)의 비중이 세척수의 비중보다 낮게 되면 세척펌프(3)와 배수펌프(5)가 정지된 상태에서도 선택부재(81)가 세척수의 비중에 의해 상승되어 배출관(42)의 입구를 막게 되며, 또한 상기 배수펌프(5)가 가동시 배출되는 세척수의 흐름에 따라 유동되어 배출관(42)의 입구를 막게 되므로 원활한 배수행정을 진행할 수 없게 된다.That is, when the specific gravity of the selection member 81 is lower than the specific gravity of the washing water, even if the washing pump 3 and the drain pump 5 are stopped, the selection member 81 is raised by the specific gravity of the washing water to discharge the discharge pipe 42. The inlet is blocked, and the drain pump 5 flows according to the flow of the washing water discharged during operation, thereby blocking the inlet of the discharge pipe 42, so that the smooth drainage stroke cannot be performed.

상기와 같이 배출관(42)의 입구가 개방되면 포집면(72)에 모여 있던 찌꺼기들은 배수펌프(5)의 가동에 의해 배출관(42)을 통과하여 세척수와 함께 외부에 배출된다.As described above, when the inlet of the discharge pipe 42 is opened, the debris collected on the collecting surface 72 passes through the discharge pipe 42 by the operation of the drainage pump 5 and is discharged to the outside together with the washing water.

즉, 상기 배수펌프(5)가 가동을 하게 되면 세척수와 찌꺼기는 배수호스(51)를 통해 외부에 배출되는 바, 상기 포집실(7)에서 있던 세척수는 입구가 개방된 배출관(42)을 통해 배수펌프(5)에 유입된다.That is, when the drain pump 5 is operated, the washing water and the residues are discharged to the outside through the drain hose 51, and the washing water in the collection chamber 7 is discharged through the discharge pipe 42 having the inlet open. It flows into the drain pump 5.

이때, 상기 포집실(7)의 포집면(72)에는 세척수에 포함되었던 찌꺼기들이 제 2 필터(71)에 의해 걸러져 모여 있게 되므로, 상기 배출관(42)으로 유입되는 세척수는 포집면(72)에 쌓여 있는 찌꺼기들을 쓸어가지고 함께 배수펌프(5)에 공급되고, 배수호스(51)를 통과하여 외부에 배출되는 것이다.At this time, since the debris contained in the washing water is collected and collected by the second filter 71 on the collecting surface 72 of the collecting chamber 7, the washing water flowing into the discharge pipe 42 is collected on the collecting surface 72. Sweep up the accumulated debris is supplied to the drain pump (5), and is discharged to the outside through the drain hose (51).

따라서, 상기 식기(11) 세척중에 발생된 찌꺼기는 포집면(72)에 모여 쌓이게 되고, 다시 세척펌프(3) 내에 공급되지 않으므로 식기(11)를 재오염시키는 경우가 발생되지 않을 뿐 아니라, 세척펌프(3)는 정지하고 배수펌프(5)는 가동하므로서 포집면(72)에 포집된 찌꺼기들이 외부에 전부 배출하게 되어, 세척효율이 향상되는 것이다.Therefore, the debris generated during the washing of the tableware 11 is collected and accumulated on the collecting surface 72, and is not supplied into the washing pump 3 again, so that the contamination of the tableware 11 does not occur. As the pump 3 stops and the drainage pump 5 operates, all the debris collected on the collecting surface 72 is discharged to the outside, thereby improving the washing efficiency.

한편, 상기 선택부재(81)는 도면에 도시된 바와같이 볼로만 형성할 수 있는 것이 아니라, 세척수의 흐름에 따라 선택적으로 관의 입구를 개폐시킬 수 있는 선택밸브등으로도 구성할 수 있음은 자명하다.On the other hand, the selection member 81 is not only can be formed by the ball as shown in the figure, it can also be configured as a selection valve for selectively opening and closing the inlet of the pipe according to the flow of the washing water. Do.

이와같이 된 본 발명은 분기관과 배출관 및 포집실의 연결부위에 수로선택수단을 설치하여 세척시 발생된 찌꺼기를 포집하고 배수시 전부 배출시킴으로서, 집수조에서 분산된 찌꺼기가 세척펌프에 공급되고 다시 노즐에 의해 분사되어 세척된 식기를 재오염시키는 것을 방지함과 동시에 세척효율을 향상시킬 수 있는 유용한 효과를 갖는다.The present invention thus achieved by installing a water channel selection means at the connection of the branch pipe and the discharge pipe and the collection chamber to collect the debris generated during washing and to discharge all when drained, the debris dispersed in the water collection tank is supplied to the washing pump and back to the nozzle By preventing the re-contamination of the dishes washed by the spray and at the same time has a useful effect to improve the washing efficiency.
