본 발명은 식기세척기에 관한 것으로, 보다 상세하게는 구조적인 특성상 헹굼작용이 더욱 청결하게 이루어지는 업소용 식기세척기에 관한 것이다.The present invention relates to a dishwasher, and more particularly to a commercial dishwasher in which the rinsing action is more clean due to its structural characteristics.

일반적으로, 대형 음식점 등에서 많이 사용되는 업소용 식기세척기는 도 1과 도 2에 나타난 것과 같이 내부에 세척수조(12)와 헹굼수조(14)를 구성하는 저수탱크(10)와, 상기 저수탱크(10)의 상방에 아래위로 이격 구성된 상하 세척임펠러(20)(22) 및 상하 헹굼임펠러(30)(32)와, 상기 상하 세척임펠러(20)(22) 사이에 형 성된 세척공간을 개폐하는 슬라이드 커버(40)와, 상기 세척공간내에 개재된 랙(42) 등을 포함하여 이루어져 있다.In general, commercial dishwashers used in large restaurants, such as the storage tank 10 constituting the washing tank 12 and the rinsing tank 14 as shown in Figure 1 and 2, and the storage tank (10) Slide cover for opening and closing the washing space formed between the upper and lower washing impeller 20, 22 and the upper and lower rinsing impeller 30, 32 and the upper and lower washing impeller 20, 22 configured to be spaced up and down above) 40 and the rack 42 interposed in the washing space.

상기 세척임펠러(20)(22)와 헹굼임펠러(30)(32)는 각기 세척수관(24) 및 헹굼수관(34)을 통해 세척수조(12) 및 헹굼수조(14)와 연결되어 있는데, 상기 헹굼수관(34)은 세척수관(24)의 일측에 배치되며 그 선단이 각기 상하 하우징(36)(36')에 공통연결되어 있으며, 세척임펠러(20)(22)와 헹굼임펠러(30)(32)는 상기 하우징(36)(36')에 회전 가능하게 동축연결되어 있다.The washing impeller 20, 22 and the rinsing impeller 30, 32 are respectively connected to the washing water tank 12 and the rinsing water tank 14 through the washing water pipe 24 and the rinsing water pipe 34. The rinsing water pipe 34 is disposed at one side of the washing water pipe 24 and its front end is commonly connected to the upper and lower housings 36 and 36 ', respectively, and the washing impellers 20 and 22 and the rinsing impeller 30 ( 32 is rotatably coaxially connected to the housings 36 and 36 '.

상기 상부 세척임펠러(20)와 상부 헹굼임펠러(30)에는 하방으로 다수개의 노즐(201)(301)이 구성되어 있으며, 하부 세척임펠러(22)와 하부 헹굼임펠러(32)에는 상방으로 다수개의 노즐(221)(321)이 구성되어 있다.The upper washing impeller 20 and the upper rinsing impeller 30 are configured with a plurality of nozzles 201 and 301 downward, and the lower washing impeller 22 and the lower rinsing impeller 32 with a plurality of nozzles upward. 221 and 321 are configured.

저수탱크(10)의 내부에는 세척수관(24)을 통해 세척수조(12) 내의 세척수를 상하 세척임펠러(20)(22)로 공급하는 세척펌프(28) 및, 헹굼수관(34)을 통해 헹굼수조(14) 내의 헹굼수를 헹굼임펠러(30)(32)로 공급하는 헹굼펌프(38)가 구비되어 있다.The storage tank 10 rinses through a washing pump 28 and a rinsing water pipe 34 which supply the washing water in the washing water tank 12 to the upper and lower washing impellers 20 and 22 through the washing water pipe 24. A rinse pump 38 for supplying the rinsing water in the water tank 14 to the rinsing impellers 30 and 32 is provided.

그리고, 저수탱크(10)의 헹굼수조(14)내에는 저수된 용수를 일정온도이상으로 유지하여 세척 및 헹굼효과를 높이기 위한 히터(미도시)가 장착되어 있다.In addition, a heater (not shown) is installed in the rinsing water tank 14 of the water storage tank 10 to increase the washing and rinsing effect by maintaining the stored water at a predetermined temperature or more.

이와 같은 종래 식기세척기에 의한 식기세척과정은 저수단계, 세척단계, 대기단계, 헹굼단계 순으로 진행되는데, 각 단계별 작용을 설명하면 다음과 같다.The dish washing process according to the conventional dishwasher proceeds in the order of the water storage step, the washing step, the waiting step, and the rinsing step.

저수단계에서는 식기세척기 외부에 구비된 순간온수기 등의 열원을 사용하여 상온의 용수를 일정온도 이상으로 가열한 다음, 세척수조(12)와 헹굼수조(14)로 공 급하여, 세척수조(12)와 헹굼수조(14)를 채우게 되는데, 헹굼수조(14)로 유입된 용수는 히터에 의해 가열됨으로써 일정온도를 유지하게 된다.In the water storage stage, the water at room temperature is heated to a predetermined temperature or more using a heat source such as an instantaneous water heater provided outside the dishwasher, and then, the washing water tank 12 and the rinsing water tank 14 are supplied. The rinsing tank 14 is filled, and the water flowing into the rinsing tank 14 is maintained by a heater to maintain a constant temperature.

저수단계를 통해 일정치의 세척용수가 확보된 후에는 세척단계가 진행되는데, 세척단계에서는 도 3에 나타난 것과 같이 세척수에 소량의 세제가 혼입된 상태에서 세척펌프(26)에 의해 세척수(도면상 실선 화살표시)가 이송되어 상하 세척임펠러(20)(22)의 노즐(201)(221)을 통해 분사됨으로써 랙(42)에 담겨진 식기를 세척하게 되며, 분사된 세척수는 세척수조 상단의 거름망(121)을 거쳐 다시 세척수조로 유입된다음, 재차 세척펌프(28)를 통해 이송되는 순환과정을 일정기간동안 반복하게 된다.After a certain amount of washing water is secured through the water storage step, the washing step is performed. In the washing step, the washing water is washed by the washing pump 26 in a state in which a small amount of detergent is mixed into the washing water as shown in FIG. Solid arrow) is transported and sprayed through the nozzles 201 and 221 of the upper and lower washing impellers 20 and 22 to wash the dishes contained in the rack 42, and the sprayed washing water is filtered through the top of the washing tank ( After 121) is introduced into the washing tank again, the circulation process which is conveyed through the washing pump 28 again is repeated for a certain period of time.

세척단계에서 상기 세척임펠러(20)(22)는 노즐(201)(221)을 통해 분사되는 세척수의 압력에 의해 회전하게 됨으로써 세척효율을 높이게 된다. In the washing step, the washing impellers 20 and 22 are rotated by the pressure of the washing water sprayed through the nozzles 201 and 221 to increase the washing efficiency.

세척단계가 종료되면, 세척임펠러(20)(22)를 통한 세척수의 분사작동이 멈춘 후 부터 헹굼펌프(38) 및 헹굼임펠러(30)(32)의 작동이 시작되기 전까지 일정한 시간차를 두어 세척임펠러(20)(22)에 잔류된 세척수가 자중에 의해 어느정도 배출되도록 함으로써 헹굼단계에서 헹굼수와 세척수가 혼합되는 것을 방지하는 대기단계가 진행된다.When the washing step is completed, the washing impeller is given a certain time difference from the start of the operation of the rinsing pump 38 and the rinsing impeller 30, 32 from the stop of the spray operation of the washing water through the washing impeller 20, 22 By the washing water remaining in the (20) (22) to some extent by the self-weight, the waiting step for preventing the rinsing water and the washing water mixed in the rinsing step is carried out.

헹굼단계에서는 헹굼수조(14)에 저수된 헹굼수(도면상 가성선 화살표시)가 헹굼펌프(38)를 통해 이송되어 헹굼임펠러(30)(32)를 통해 분사됨으로써 식기에 잔류된 세제성분을 제거하게 된다. 헹굼작용시에 사용되는 헹굼수는 순환사용되지 않고, 일회 사용된후 배수된다.In the rinsing step, the rinsing water stored in the rinsing tank 14 (when the caustic arrow in the drawing) is transferred through the rinsing pump 38 and sprayed through the rinsing impellers 30 and 32 to remove the detergent components remaining in the tableware. Will be removed. The rinsing water used in the rinsing operation is not circulated but drained after being used once.

여기서, 상기 헹굼임펠러(30)(32)는 세척임펠러(20)(22)와 마찬가지로 노즐(301)(321)로부터 분사되는 헹굼수의 압력에 의해 회전하게 됨으로써 헹굼효율을 높이게 된다.Here, the rinsing impeller 30, 32 is rotated by the pressure of the rinsing water sprayed from the nozzles 301, 321, like the washing impeller 20, 22 to increase the rinsing efficiency.

한편, 상술한 바와 같은 종래 업소용 식기세척기에 의하면 헹굼작용 시의 효율을 높이기 위해 세척단계가 종료된 후, 헹굼단계가 시작되기 전까지 앞서 말한 바와 같이 일정 시간동안 상부 세척임펠러(20) 내에 잔류된 세척수가 자연배출되도록 하는 대기단계가 진행되는데, 이에 따르면, 잔류 세척수의 배출정도가 극히 미미하기 때문에, 결과적으로 헹굼단계 종료후에 상부 세척임펠러(20)로부터 잔류된 세척수가 떨어져 식기에 묻게 됨으로써 헹굼효과를 떨어뜨리게 된다.On the other hand, according to the conventional commercial dishwasher as described above, after the washing step is finished to increase the efficiency during the rinsing action, the washing water remaining in the upper washing impeller 20 for a predetermined time as described above before the rinsing step begins The process of waiting for the natural discharge is carried out. According to this, since the discharge degree of the residual washing water is extremely small, as a result, after the end of the rinsing step, the remaining washing water is dropped from the upper washing impeller 20 and is buried in the dishes, thereby providing a rinsing effect. Dropped.

또한, 세척단계에서 세척펌프(28)에 의해 강한 압력으로 이송되는 세척수가 세척임펠러(20)(22)에서 분사됨과 동시에 일부가 헹굼수관(34)을 타고 흘러 내려서 헹굼수관(34) 안으로 역유동되어 헹굼수조(14)로 유입됨으로써 헹굼수를 오염시키는 현상이 발생하게 되는 등, 종래기술에 의하면 결과적으로 식기가 깨끗하게 세척되지 않는다는 문제점이 발생한다.In addition, at the same time the washing water is transferred to the strong pressure by the washing pump 28 in the washing step is sprayed from the washing impeller 20, 22 and at the same time a portion flows down the rinsing water pipe 34 to flow back into the rinsing water pipe 34 As a result, a phenomenon in which the rinsing water is contaminated by being introduced into the rinsing water tank 14 occurs, and according to the related art, a problem arises that the tableware is not cleaned as a result.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로, 세척단계에서 세척수가 헹굼수관으로 유입되거나, 세척임펠러에 잔류된 세척수가 헹굼단계 이후에 식기로 떨어져 식기를 더럽히는 현상을 방지함으로써 세척효과를 높일 수 있는 업소용 식기세척기의 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, to increase the cleaning effect by preventing the washing water flowing into the rinsing water pipe in the washing step, or the washing water remaining in the washing impeller falls into the dishes after the rinsing step to dirty the dishes.

먼저, 저수단계에서는 종래와 마찬가지로 식기세척기 외부에 구비된 순간온수기 등의 열원을 사용하여 상온의 용수를 일정온도 이상으로 가열한 다음, 세척수조(12)와 헹굼수조(14)로 공급하여, 세척수조(12) 및 헹굼수조(14)를 채우게 되는데, 헹굼수조(14)로 유입된 용수는 히터에 의해 가열됨으로써 일정온도를 유지하게 된다.First, in the water storage step, the water at room temperature is heated to a predetermined temperature or more using a heat source such as an instantaneous water heater provided outside the dishwasher, and then supplied to the washing water tank 12 and the rinsing water tank 14 for washing. The water tank 12 and the rinsing water tank 14 are filled, and the water introduced into the rinsing water tank 14 is maintained by a heater to maintain a constant temperature.

저수단계를 통해 일정치의 세척용수가 확보된 후에는 세척단계가 진행되는데, 세척단계에서는 도 5a에 나타난 것과 같이 세척수에 소량의 세제가 혼입된 상 태에서 세척펌프(28)에 의해 세척수가 이송되어 상하 세척임펠러(20)(22)의 노즐(201)(221)을 통해 분사됨으로써 랙(42)에 담겨진 식기를 세척하게 되며, 분사된 세척수는 세척수조 상단의 거름망(121)을 거쳐 다시 세척수조(12)로 유입된다음, 재차 세척펌프(28)를 통해 이송되는 순환과정을 일정기간동안 반복하게 된다.After a certain amount of washing water is secured through the water storage step, a washing step is performed. In the washing step, the washing water is transferred by the washing pump 28 in a state where a small amount of detergent is mixed into the washing water as shown in FIG. 5A. It is sprayed through the nozzles 201 and 221 of the upper and lower washing impellers 20 and 22 to wash the dishes contained in the rack 42, and the sprayed washing water is washed again through the sieve 121 at the top of the washing tank. After being introduced into the water tank 12, the circulation process, which is transferred through the washing pump 28 again, is repeated for a predetermined period of time.

한편, 세척단계에서 가압이송된 세척수가 세척임펠러(20)(22)에서 분사됨과 동시에 헹굼수관(34) 및 보조헹굼수관(50)으로 역류될 수도 있는데, 이와 같은 세척수 역류현상에 의해 헹굼수관(34) 및 보조헹굼수관(50)을 통해 헹굼수조(14)로 역류하는 세척수는 헹굼수관(34) 및 보조헹굼수관(50)에 각각 장착된 체크밸브(39)(54)에 의해 차단되기 때문에 헹굼수조(14)로 유입되지 않는다.Meanwhile, the washing water pressurized and transferred in the washing step may be sprayed from the washing impellers 20 and 22 and simultaneously flowed back to the rinsing water pipe 34 and the auxiliary rinsing water pipe 50. 34) and the wash water flowing back to the rinsing water tank 14 through the auxiliary rinsing water pipe 50 are blocked by the check valves 39 and 54 mounted to the rinsing water pipe 34 and the auxiliary rinsing water pipe 50, respectively. It does not flow into the rinse tank 14.

이어서, 진행되는 예비헹굼단계에서는 도 5b에 나타난 것과 같이 세척임펠러(20)의 작동이 멈춘다음, 보조헹굼펌프(52)에 의해 가압이송되는 헹굼수가 보조헹굼수관(50)을 통해 상부 세척임펠러(20)로 유입되어 노즐(201)을 통해 일정기간 동안 배출됨으로써, 상부 세척임펠러(20)내에 잔류된 세척수를 배출시키게 된다.Subsequently, in the preliminary rinsing step, as shown in FIG. 5B, after the operation of the washing impeller 20 is stopped, the rinsing water pressurized by the auxiliary rinsing pump 52 is supplied to the upper washing impeller (50). 20 is introduced into and discharged through the nozzle 201 for a predetermined time, thereby discharging the washing water remaining in the upper washing impeller 20.

그리고, 헹굼단계에서는 도 5c에 나타난 것과 같이 헹굼수관(34)을 통해 헹굼수가 이송되어 상하 헹굼임펠러(30)(32)를 통해 분사되는데, 이때 상부 헹굼임펠러(30)에서는 상면에 형성된 보조노즐(302)을 통해서도 헹굼수가 상방으로 배출되어 상부 세척임펠러(20)의 표면에 묻어있는 세척수를 씻어내게 된다. In the rinsing step, as shown in FIG. 5C, the rinsing water is transferred through the rinsing water pipe 34 and sprayed through the upper and lower rinsing impellers 30 and 32. In this case, the upper rinsing impeller 30 has an auxiliary nozzle formed on the upper surface ( The rinsing water is discharged upward through the 302 to wash off the washing water on the surface of the upper washing impeller 20.

따라서, 본 실시예에 의하면 세척단계에서 세척수가 헹굼수조(14)로 역유입되어 헹굼수를 오염시키는 현상이 발생하지 않을 뿐만 아니라, 헹굼단계가 종료된 후에도 세척임펠러(20)(22)로부터 잔류된 세척수가 떨어지거나 하여 식기를 더럽히 는 현상 또한 발생하지 않게 된다. Therefore, according to the present embodiment, not only does the washing water flow back into the rinsing tank 14 in the washing step, and contaminates the rinsing water, but also remains from the washing impeller 20 and 22 even after the rinsing step is completed. Dirty dishes will not run out and the dishes will not be soiled.

이상에서 살펴본 바와 같이 본 발명에 따른 업소용 식기세척기에 의하면 세척단계에서 세척수가 헹굼조로 역유입되어 헹굼수를 오염시키는 현상이 발생하지 않을 뿐만 아니라, 헹굼단계가 종료된 후에도 세척임펠러내에 잔류된 세척수가 떨어지거나 하여 식기를 더럽히는 현상 또한 발생하지 않게 되는 등, 결과적으로 세척효율이 향상된다는 이점이 있다. As described above, according to the commercial dishwasher according to the present invention, the washing water is introduced into the rinsing tank in the washing step so that the rinsing water is not contaminated, and the washing water remaining in the washing impeller even after the rinsing step is completed. As a result, the phenomenon of dirtying the dishes due to falling, etc. does not occur. As a result, the cleaning efficiency is improved.
