이하, 종래기술에 따른 식기세척기를 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, a dishwasher according to the prior art will be described with reference to the accompanying drawings.

도 1은 종래기술에 따른 식기세척기를 나타낸 단면도이다.1 is a cross-sectional view showing a dish washer according to the prior art.

도 1에 도시된 바와 같이, 종래기술에 따른 식기세척기는 내부에 세척조(11)가 형성된 본체(10)와, 상기 세척조(11)의 전면개구부를 상하방향을 따라서 회동개폐하는 도어(12)와, 상기 세척조(11)의 하측에 설치되고 정역구동에 의해 세척수의 급수 및 배수를 조정하는 급·배수일체형 세척수펌프(13)와, 상기 세척조(11)의 상부 및 하부영역에 설치되어 상기 세척수펌프(13)로부터의 세척수를 세척조(11)로 공급하는 주급수로(14)를 포함하여 구성된다.As shown in FIG. 1, the dishwasher according to the related art includes a main body 10 having a washing tank 11 formed therein, and a door 12 rotating and opening in a vertical direction in a front opening of the washing tank 11. , A water supply / drainage integral wash water pump 13 installed at the lower side of the washing tank 11 and adjusting the water supply and drainage of the washing water by forward and reverse driving, and installed at the upper and lower regions of the washing tank 11 and the washing water pump; And a main water supply channel 14 for supplying the washing water from (13) to the washing tank 11.

그리고, 상기 세척조(11)내의 상부 및 하부영역에 각각 설치되어 세척될 식기를 수용하는 상부식기바스켓(21) 및 하부식기바스켓(22)과, 상기 상부식기바스켓(21)과 하부식기바스켓(22)의 각각에 부속되어 상기 주급수로(14)로부터 세척수를 공급받아 해당 식기바스켓(21,22)을 향하여 세척수를 분사하는 상부분사노즐부(23) 및 하부분사노즐부(24)를 더 포함하여 구성된다.In addition, the upper and lower dish baskets 21 and 22 to accommodate the dishes to be installed and washed in the upper and lower regions of the washing tank 11, the upper dish basket 21 and the lower dish basket 22, respectively. And a top spray nozzle part 23 and a lower part nozzle part 24 which are supplied to each of the main body 14 to receive the washing water from the main water supply channel 14 and spray the washing water toward the corresponding dish baskets 21 and 22. It is configured by.

한편, 상기 세척조(11)의 저부에는 세척수를 집수할 수 있도록 상향개구된 사각형상을 가지는 섬프케이스(30)가 설치되고, 상기 섬프케이스(30)에는 세척수내의 비교적 큰 찌꺼기를 걸러주는 노말필터(31)와 비교적 작은 찌쩌기를 걸러주는 미세필터(32)가 구비되어 있다.On the other hand, the bottom of the washing tank 11 is provided with a sump case 30 having a rectangular shape upwardly opened to collect the washing water, and the sump case 30 filters a normal filter that filters relatively large debris in the washing water ( 31) and a fine filter 32 to filter out relatively small bladders.

상기와 같이 구성된 종래기술에 따른 식기세척기의 작용에 대하여 설명하면 다음과 같다.Referring to the operation of the dishwasher according to the prior art configured as described above are as follows.

우선, 사용자가 세척할 식기를 식기세척기에 투입한 후 세척코스를 선택하면 도시되지 않은 제어부는 세척조(11)내에 세척수가 공급되도록 세척수펌프(13)를 정회전시킨다.First, when the user inserts the dishes to be washed in the dishwasher and selects the washing course, the controller (not shown) rotates the washing water pump 13 forward so that the washing water is supplied into the washing tank 11.

상기 세척조(11)내에 공급된 세척수는 섬프케이스(30)의 집수부(30a)에 집수된 후 세척수펌프(13)에 의해 흡입되어 주급수로(14)를 통해 상부 및 하부분사노즐부(23,24)로 각각 공급된다.The washing water supplied in the washing tank 11 is collected by the water collecting unit 30a of the sump case 30, and then is sucked by the washing water pump 13, and the upper and lower four nozzle parts 23 are supplied through the main water supply passage 14. 24, respectively.

상기 상부 및 하부분사노즐부(23,24)로 공급된 세척수는 각 분사노즐을 통해 분사되면서 상부 및 하부식기바스켓(21,22)에 수용되어 있는 식기를 세척하게 된다.The washing water supplied to the upper and lower four nozzle parts 23 and 24 is sprayed through the respective injection nozzles to wash the dishes accommodated in the upper and lower tableware baskets 21 and 22.

그리고, 식기를 세척한 후 낙하한 세척수는 섬프케이스(30)에 마련되어 있는노말필터(31)와 미세필터(32)를 차례대로 거치면서 세척수내의 찌꺼기가 걸러진후 다시 세척조(11)내로 유입하게 된다.After washing the dishes, the washing water dropped through the normal filter 31 and the fine filter 32 provided in the sump case 30 is filtered out of the washing water and flows into the washing tank 11 again. .

한편, 상기 노말필터(31)와 미세필터(32)를 거치면서 걸러진 세척수중의 찌꺼기들은 섬프케이스(30)내에 잔류 수집되어 배수행정시 세척수펌프(13)에 의해 흡입되어 배수로(15)를 통해 세척수와 함께 외부로 배출된다.Meanwhile, debris in the washing water filtered while passing through the normal filter 31 and the fine filter 32 is collected in the sump case 30 and is sucked by the washing water pump 13 during drainage, and is discharged through the drainage path 15. It is discharged to the outside with the wash water.

그러나, 상기와 같이 구성 및 작용하는 종래기술에 따른 식기세척기는 세척할 식기의 형상을 고려하지 않고 일괄적인 세척을 하므로 세척효율이 저하되는 문제점이 있었다.However, the dishwasher according to the related art, which is configured and functions as described above, has a problem in that washing efficiency is reduced because batch washing is performed without considering the shape of the dishes to be washed.

즉, 접시와 같이 납작한 식기를 세척할 경우와 밥그릇과 같이 오목한 식기를 세척할 경우에 일괄적으로 동일한 세척코스로 세척을 함으로써, 세척수와 세제등의 낭비가 심해 기존의 손설거지에 비하여 수도비용과 세제비용등의 유지비용이 절약되는데 한계가 있었다.In other words, when washing flat dishes such as plates and washing concave dishes such as rice bowls, they are washed in the same washing course at once, resulting in a great waste of washing water and detergent. There was a limit in saving maintenance costs such as tax and tax.

또한, 분사노즐에서 분사되는 세척수의 분사압과 분사각도가 세척할 식기의 형상에 상관없이 일정하기 때문에, 오목한 식기를 세척할 경우에 정확하고 깨끗한 세척을 하기가 어려웠다.In addition, since the spray pressure and the spray angle of the washing water sprayed from the spray nozzle are constant regardless of the shape of the dish to be washed, it is difficult to accurately and cleanly wash the concave dish.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 식기세척기 내에 세척할 식기의 형상을 센싱하는 형상감지센서를 구비하여, 식기의 형상에 알맞는 세척코스를 자동적으로 선택하고 이에 적합한 분사량과 분사압 및 분사각도를 갖는 세척수로 식기를 세척할 수 있어, 세척수를 절약하면서도 신속하고 깨끗한 세척이 가능함으로써 세척효율을 향상시킬 수 있는 식기세척기를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and provided with a shape sensor for sensing the shape of the dishes to be washed in the dishwasher, automatically selects the washing course suitable for the shape of the dish, and the injection amount and It is an object of the present invention to provide a dishwasher capable of washing dishes with washing water having an injection pressure and an injection angle, thereby improving washing efficiency by allowing a quick and clean washing while saving washing water.

본 발명에 따른 식기세척기에서도 세척수는 종래기술에서와 마찬가지로 동일한 경로로 유동하기 때문에 이에 대한 설명은 중복되므로 생략하고, 본 발명에 따른 식기세척기의 세척제어방법에 대하여 설명하기로 한다.In the dishwasher according to the present invention, since the washing water flows in the same path as in the related art, the description thereof will not be repeated, and thus the washing control method of the dishwasher according to the present invention will be described.

우선, 사용자가 세척할 식기를 상부식기바스켓(121)과 하부식기바스켓(122)에 정열하여 투입하고 식기세척기를 작동시키면, 제1열발광부(141a)와 제2열발광부(141b)에서 각각 대향된 제1열수광부(142a)와 제2열수광부(142b)로 조사되는 빛이 차단 및 통과 됨에 따라 식기의 형상을 센싱한다.First, when the user arranges the dishes to be washed in the upper dish basket 121 and the lower dish basket 122 and operates the dishwasher, the first heat emitting unit 141a and the second heat emitting unit 141b may be used. As the light irradiated to the first heat receiving unit 142a and the second heat receiving unit 142b is blocked and passed through, the shape of the tableware is sensed.

즉, 세척할 식기가 접시와 같이 높이가 제1열발광부(141a)의 높이 미만으로 오목도가 작은 식기이면 제1열발광부(141a)와 제2열발광부(141b)에서 조사되는 빛이 각각 제1,2열수광부(142a,142b)로 수광되고, 세척할 식기의 높이가 제1열발광부(141a)와 제2열발광부(141b) 사이의 높이로 오목도가 중간인 식기이면 제1열발광부(141a)에서 조사되는 빛은 차단되고 제2열발광부(141b)에서 조사되는 빛은 제2열수광부(141b)로 수광되며, 세척할 식기의 높이가 제2열발광부(141b) 이상으로 오목도가 큰 식기이면 제1,2열발광부(141a,141b)에서 각각 조사되는 빛이 모두 차단됨으로써, 세척할 식기의 형상을 센싱할 수 있다.(제1단계)That is, when the dish to be washed is a dish having a small recess such that the height is less than the height of the first heat emitter 141a, such as a plate, the light irradiated from the first heat emitter 141a and the second heat emitter 141b. The dishes are received by the first and second heat receiving units 142a and 142b, respectively, and the height of the dishes to be washed is the height between the first heat emitting unit 141a and the second heat emitting unit 141b. When the light emitted from the first heat emitting unit 141a is blocked, the light emitted from the second heat emitting unit 141b is received by the second heat receiving unit 141b, and the height of the dishes to be cleaned is the second heat emitting unit. If the dishes have a large concave portion above the portion 141b, all of the light irradiated from the first and second heat emitting units 141a and 141b may be blocked, thereby sensing the shape of the dishes to be cleaned.

그리고, 상기 제1,2열발광부(141a,141b)와 제1,2열수광부(142a,142b)로 이루어진 형상감지센서와 전기적으로 연결된 제어부(150)는 센싱된 신호를 입력받아 식기의 형상을 비교판단하고(제2단계), 비교 판단 결과에 따라서 식기의 세척코스를 선택한다.The controller 150 electrically connected to a shape detecting sensor including the first and second heat emitting parts 141a and 141b and the first and second heat receiving parts 142a and 142b receives a sensed signal to form a dish. Compare the judgment (step 2), and select the washing course of the dishes according to the comparison judgment result.

즉, 상기 제어부(150)에서 비교 판단한 결과 식기의 형상이 오목도가 큰 식기이면 다시말해 제1,2열발광부(141a,141b)에서 각각 조사되는 빛이 모두 차단되는 경우이면 강력한 세척이 수행되도록 강력세척코스를 설정하고, 오목도가 중간인 식기이면 다시말해 제1열발광부(141a)에서 조사되는 빛은 차단되고 제2열발광부(141b)에서 조사되는 빛은 제2열수광부(142b)로 수광되는 경우이면 표준적인 세척이 수행되도록 표준세척코스를 설정하며, 오목도가 작은 식기이면 다시말해 제1열발광부(141a)와 제2열발광부(141b)에서 조사되는 빛이 각각 제1,2열수광부(142a,142b)로 수광되는 경우이면 약한 세척이 수행되도록 약세척코스를 설정한다.That is, if the shape of the tableware is a tableware having a large concave result as compared with the control unit 150, that is, if all of the light irradiated from the first and second heat emitting units 141a and 141b is blocked, a strong washing is performed. If the washing course is set to be strong, and the recess is medium, the light irradiated from the first heat emitting unit 141a is blocked, and the light irradiated from the second heat emitting unit 141b is blocked by the second heat receiving unit ( 142b), the standard washing course is set so that standard washing is performed. In the case of a dish having a small concave, in other words, the light irradiated from the first heat emitting unit 141a and the second heat emitting unit 141b is When the light is received by the first and second heat receiving units 142a and 142b, the weak washing course is set to perform a weak washing.

또한, 상기 제어부(150)에서 비교 판단한 결과 세척할 식기의 형상이 오목도가 큰 식기와, 오목도가 중간인 식기와, 오목도가 작은 식기 중에서 2종류 이상의 식기 형상인 것으로 판단되면 다시말해 제1열발광부(141a)에서 조사되는 빛이 제1열수광부(142a)의 일부에서는 수광되고 일부에서는 차단되는 경우 또는 제2열발광부(141b)에서 조사되는 빛이 제2열수광부(142b)의 일부에서는 수광되고 일부에서는 차단되는 경우 또는 상기 두가지 경우가 동시에 해당되는 경우에는 식기형상이 2종류 이상인 것으로 판단하여, 각각의 식기 형상에 따른 세척 과정이 교대로 수행되도록 혼합코스를 설정한다.(제3단계)In addition, if it is determined that the shape of the dishes to be washed is two or more types of tableware among the dishes having a large concave degree, the ones having a middle concave degree, and the one having a small concave degree, as a result of comparing and judging by the controller 150. When the light irradiated from the first heat emitting unit 141a is received by a part of the first heat receiving unit 142a and is blocked in part, or the light irradiated by the second heat emitting unit 141b is the second heat receiving unit 142b. In some cases, when the light is received in some cases and blocked in some cases or when the two cases are applicable at the same time, it is determined that there are two or more kinds of dish shapes, and the mixing course is set to alternately perform the washing process according to each dish shape. 3rd step)

그리고, 상기와 같이 세척코스가 선택되면, 상기 제어부(150)는 선택된 식기의 세척코스에 따라 세척수펌프(113)와 노즐구동부(123b,124b)를 구동 제어하여 선택된 세척코스를 수행한다.When the washing course is selected as described above, the controller 150 controls the washing water pump 113 and the nozzle driving units 123b and 124b according to the washing course of the selected dish to perform the selected washing course.

다시 말해, 선택된 세척코스가 강력세척코스일 경우에는 세척수펌프(113)의 회전수를 최대로 하여 노즐(123a,124a)에서 분사되는 세척수의 분사량과 분사압을 최대로 하고, 노즐구동부(123b,124b)의 각도를 변각시켜 이와 연결된 노즐(123a,124a)에서 분사되는 세척수의 분사각도를 변화시킴으로써 식기의 안쪽 오목한 부분을 집중적으로 세척할 수 있다.In other words, when the selected washing course is a strong washing course, the rotation speed of the washing water pump 113 is maximized to maximize the injection amount and the injection pressure of the washing water sprayed from the nozzles 123a and 124a, and the nozzle driving unit 123b, By changing the angle of the 124b to change the spray angle of the washing water sprayed from the nozzles 123a and 124a connected thereto, the inner concave portion of the tableware may be concentrated.

그리고, 선택된 세척코스가 표준세척코스일 경우에는 세척수펌프(113)의 회전수를 중간치로 하여 노즐(123a,124a)에서 분사되는 세척수의 분사량과 분사압을 중간치로 하고, 노즐구동부(123b,124b)의 각도를 변각시켜 이와 연결된 노즐(123a,124a)에서 분사되는 세척수의 분사각도를 변화시킴으로써 식기의 더러운 부분을 집중적으로 세척할 수 있다.When the selected washing course is a standard washing course, the rotation speed of the washing water pump 113 is set to an intermediate value, and the injection amount and the injection pressure of the washing water sprayed from the nozzles 123a and 124a are set to an intermediate value, and the nozzle driving units 123b and 124b are used. By changing the angle of the () to change the spraying angle of the washing water sprayed from the nozzles (123a, 124a) connected to it can be intensively washed dirty dishes.

또한, 선택된 세척코스가 약세척코스일 경우에는 세척수펌프(113)의 회전수를 최저로 하여 노즐(123a,124a)에서 분사되는 세척수의 분사량과 분사압을 최저로 하고, 노즐구동부(123b,124b)의 각도를 변각시켜 이와 연결된 노즐(123a,124a)에서 분사되는 세척수의 분사각도를 변화시킴으로써 세척수를 절약하면서도 최적으로 식기 세척을 수행할 수 있다.(제4단계)In addition, when the selected washing course is a weak washing course, the rotation speed of the washing water pump 113 is minimized to minimize the injection amount and the spray pressure of the washing water sprayed from the nozzles 123a and 124a, and the nozzle driving units 123b and 124b. By changing the angle of the () to change the spray angle of the washing water sprayed from the nozzles (123a, 124a) connected to it can save the washing water and perform the dish washing optimally (step 4).

그리고, 각각의 세척코스에 맞는 세척과정을 수행한 후, 세척시간이 설정시간에 도달할 경우 식기세척기의 작동을 중지하고 식기세척을 완료한다.Then, after performing a washing process for each washing course, when the washing time reaches the set time stops the operation of the dishwasher and completes dish washing.

상기와 같이, 본 발명에 따른 식기세척기는 세척될 식기의 형상에 맞추어 세척코스를 자동으로 선택하여 이에 필요한 세척수의 분사압과 분사량으로 식기를 세척함으로써 세척수와 전기에너지를 절약하면서도 신속한 세척을 할 수 있고, 분사되는 세척수의 분사각도를 조절하여 세척수가 직접 분사되기 어려운 오목한 식기의 안쪽 깊숙한 부분까지 세척을 함으로써 정확하고 깨끗한 세척을 할 수 있어 식기세척기의 세척효율을 최적화시킬 수 있다.As described above, the dishwasher according to the present invention can automatically select the washing course according to the shape of the dishes to be washed to wash the dishes with the injection pressure and the injection amount of the washing water required for this, while washing water and electrical energy can be quickly washed. In addition, it is possible to optimize the cleaning efficiency of the dishwasher by adjusting the spray angle of the washing water to be sprayed to wash the deep parts of the concave dish that the washing water is difficult to spray directly, thereby enabling accurate and clean washing.

상술한 바와 같이, 본 발명은 식기세척기 내에 세척될 식기의 형상을 감지하는 형상감지센서를 구비하여 식기를 세척하기 전에 세척될 식기의 형상을 센싱하고, 센싱된 식기에 알맞는 세척수 분사량과 분사압으로 식기를 세척함으로써 물과 전기에너지를 절약하면서도 신속한 식기 세척이 가능하다.As described above, the present invention is provided with a shape sensor for sensing the shape of the dishes to be washed in the dishwasher to sense the shape of the dishes to be washed before washing the dishes, washing water injection amount and injection pressure suitable for the sensed dishes By washing dishes, it is possible to quickly wash dishes while saving water and electric energy.

또한, 식기에 분사되는 세척수의 분사각도를 조절하여 식기를 세척함으로써, 정확하고 깨끗하게 식기를 세척할 수 있어 식기세척기의 세척효율을 향상시키는 효과가 있다.In addition, by washing the dishes by adjusting the spray angle of the washing water sprayed on the dishes, the dishes can be washed accurately and clean, thereby improving the washing efficiency of the dishwasher.
