식기 세척기의 세척펌프 구동방법{DISHES WASHING MACHINE}How to drive washing pump of dishwasher {DISHES WASHING MACHINE}

본 발명은 식기 세척기의 세척펌프의 구동방법(이하, 구동방법이라 칭함)에 관한 것으로써, 상세하게는 세척수를 분사하기 위한 세척펌프의 모터를 단계적으로 높아지는 회전속도로 구동시켜 모터의 구동에 의한 소음발생 및 사용전력을 감소시키도록 한 것이다.The present invention relates to a method of driving a washing pump of a dishwasher (hereinafter referred to as a driving method), and in detail, by driving the motor of the washing pump for spraying the washing water at a stepwise higher rotational speed to drive the motor. It is to reduce noise generation and power consumption.

일반적으로 식기 세척기는 케이스의 내부에 세척조를 설치하고, 세척조의 내, 외부 주변에 식기 적재대, 세척수 분사 구동부, 식기 건조히터 등이 설치된다.In general, the dishwasher is provided with a washing tank in the inside of the case, and the inside of the washing tank, the outside of the dish mounting table, the washing water jet driving unit, the dish drying heater is installed.

상기 식기 세척기는 식기 적재대에 다수개의 식기를 적재하고, 세척수 분사 구동부의 펌프를 구동시켜 세척수가 적층된 식기에 고루 분사되도록 하여 식기에 묻은 오물을 세척한 후, 식기에 잔여하는 물기를 제거하기 위해 식기 건조히터를 가동시켜 건조하면 식기 세척과정이 완료된다.The dishwasher loads a plurality of dishes on the table, and drives the pump of the washing water jet driving unit so that the washing water is sprayed evenly on the stacked dishes, washing the dirt on the dishes, and then removing the water remaining on the dishes. In order to operate the dish drying heater to dry, the dish washing process is completed.

도 1은 상기와 같은 일반적인 식기 세척기의 세척수 분사 구동부를 나타낸 개략도이다.1 is a schematic view showing a washing water jet driving unit of the general dish washer as described above.

도면을 참조하면, 상기 세척수 분사 구동부는 세척조(1)의 하부 근접위치에 펌프(3)가 구비되고, 이 펌프(3)로 세척수가 공급되는 공급조(2)가 세척조(1) 하면에 형성되며, 상기 펌프(3)와 연결되어 세척조(1)의 내면 하부에 노즐(4)이 설치되고, 펌프(3)의 근접위치에는 노즐(4)에서 세척수가 분사되도록 하기 위해 펌프(3)를 구동시키는 모터(5)가 설치된다.Referring to the drawings, the washing water injection drive unit is provided with a pump 3 in the lower proximal position of the washing tank 1, the supply tank 2 to which the washing water is supplied to the pump 3 is formed on the lower surface of the washing tank 1 It is connected to the pump 3, the nozzle 4 is installed in the lower inner surface of the washing tank (1), the pump 3 in order to spray the washing water from the nozzle (4) in the vicinity of the pump (3) The motor 5 to drive is provided.

상기 구성의 구동부는 세제와 세척수가 세척조(1) 내부에 공급되어 공급조(2) 내로 모여지면, 모터(5)가 펌프(3)를 구동시켜 공급조(2) 내의 세척수가 세제와 용해되며 펌프(3)를 거쳐 노즐(4)로 분사되어 적재된 식기(도시되지 않음)를 세척하게 된다.When the driving unit of the above configuration is supplied with detergent and washing water inside the washing tank 1 and gathered into the feeding tank 2, the motor 5 drives the pump 3 to dissolve the washing water in the feeding tank 2 with the detergent. The utensils (not shown) which are sprayed to the nozzle 4 through the pump 3 and are loaded are washed.

여기서, 상기 식기에 잔류하는 오염물은 그 종류가 다양한데, 이들을 개략적으로 구분해보면, 물의 분사에 의해 분해되는 오염물, 세제가 용해된 세척수와 함께 가열되어 분해되는 오염물, 세척수와 함께 가열되고 세척수의 강한 압력에 의해 식기에서 탈리되는 오염물 정도로 구분된다.Here, there are various kinds of contaminants remaining in the tableware, and when they are roughly classified, contaminants decomposed by the injection of water, contaminants decomposed by washing with detergent water dissolved therein, and strong pressure of the washing water heated together with the washing water By the amount of contaminants desorbed from the tableware.

따라서, 상기 세척수를 분사하기 위한 펌프(3)를 구동시키는 모터(5)는 도 2에서와 같이 최대의 회전수(도면에서는 3300rpm)로 회전되어 그 세척력이 최대의 효율을 갖도록 한다.Accordingly, the motor 5 driving the pump 3 for spraying the washing water is rotated at the maximum rotational speed (3300 rpm in the drawing) as shown in FIG. 2 so that the washing force has the maximum efficiency.

상기와 같은 종래의 펌프 구동방법은 높은 세정효율을 갖기 위해 모터를 항상 최대의 회전수로 구동시켜야 하며, 이로인해 상기 모터에서는 많은 소음이 발생되고 전력의 소모가 많아지게 된다.In the conventional pump driving method as described above, the motor must be driven at the maximum rotational speed at all times in order to have a high cleaning efficiency, which causes a lot of noise and power consumption in the motor.

따라서, 상기와 같은 펌프 구동방법은 소비자로 하여금 제품의 신뢰도를 잃게 되며, 이에 따라 타사와의 경쟁에서 우위를 확보하기 어려운 문제점이 노출된다.Therefore, the pump driving method as described above causes the consumer to lose the reliability of the product, thereby exposing a problem that is difficult to secure an advantage in competition with other companies.

본 발명은 상기와 같은 문제점을 해소시키기 위해 창안된 것으로써, 펌프의 회전에 의한 소음과 전력을 감소시키도록 한 펌프 구동방법을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a pump driving method for reducing noise and power caused by the rotation of the pump.

상기 목적을 달성하기 위해 본 발명은, 식기에 세척수를 분사하는 과정 내에서 펌프의 구동력이 단계적으로 커지도록 한다.In order to achieve the above object, the present invention, the driving force of the pump in the step of spraying the washing water to the dish to increase step by step.

상기 본 발명은 아래와 같은 특징을 갖는다.The present invention has the following features.

본 발명은 식기의 세척과정을 세척정도에 따라 2 이상 단계의 구간으로 구분하고, 구분된 구간에 따라 모터의 회전수를 증가시키고, 모터의 회전에 의하여 구동하는 펌프는 모터의 회전수 증가에 의하여 단계적으로 높아지는 압력으로 세척수를 분사하는 것을 특징으로 한다.The present invention divides the washing process of the tableware into two or more steps according to the degree of washing, increase the number of revolutions of the motor according to the divided section, the pump driven by the rotation of the motor by increasing the number of revolutions of the motor Characterized in that the washing water is sprayed at a step by step higher pressure.

이하, 상기와 같은 본 발명의 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.

세척펌프 구동방법을 수행하기 위한 세척수 분사 구동부는 도 1에서와 같이 세척수를 세척조(1)에 적재된 식기(도시되지 않음)로 분사하기 위한 노즐(4)과, 노즐(4)에 세척수 분사압력을 제공하는 펌프(3)와, 펌프(3)로 세척수가 공급되기 위한 공급부(2)와, 상기 펌프(3)를 구동시키기 위한 구동력 발생수단인 모터(5)로 구성된다.The washing water spray driving unit for performing the washing pump driving method includes a nozzle 4 for spraying the washing water into a dish (not shown) loaded in the washing tank 1, and washing water spray pressure on the nozzle 4 as shown in FIG. It is composed of a pump (3) for providing a, a supply part (2) for supplying the washing water to the pump (3), and a motor (5) which is a driving force generating means for driving the pump (3).

상기 구성에서 세척수는 세제와 함께 세척조(1)에 공급되어 공급부(2)에 모여지고, 모여진 세척수는 펌프(3)의 구동에 의해 노즐(4)을 통하여 식기로 분사된다.In the above configuration, the washing water is supplied to the washing tank 1 together with the detergent and collected in the supply unit 2, and the collected washing water is sprayed into the dish through the nozzle 4 by driving the pump 3.

상기 펌프(3)의 구동력은 노즐(4)을 통해 분사되는 세척수의 분사압력과 비례관계를 가지며, 상기 구동력은 모터(4)의 회전수와 비례한다.The driving force of the pump 3 has a proportional relationship with the injection pressure of the washing water sprayed through the nozzle 4, and the driving force is proportional to the rotational speed of the motor 4.

여기서, 상기 세척수가 분사되는 동작구간은 펌프(3)가 구동되는 동작구간임을 의미하며 이는 도 3에서와 같이 A, B, C의 세구간으로 나누어질 수 있다.Here, the operation section in which the washing water is injected means an operation section in which the pump 3 is driven, which may be divided into three sections A, B, and C as shown in FIG. 3.

상기 구간(A)은 공급된 세척수에 세제를 용해 시키며, 세척수가 세척에 필요한 적정온도가 되기 위해 세척수를 가열하고, 노즐(4)을 통해 세척수를 식기에 분사하여 식기에 붙어 있는 오염물이 세척수에 의해 불려지는 구간이므로 세척요건의 준비단계라 한다.The section (A) dissolves the detergent in the supplied washing water, heats the washing water to obtain the proper temperature for washing, and sprays the washing water onto the dish through the nozzle (4) to contaminants attached to the dishwashing water to the washing water. It is called the preparation stage of the washing requirements because it is called.

상기 구간(B)은 공급되는 세척수를 상기 적정온도로 유지시키기 위해 계속 가열하고, 식기의 오염물을 계속 불리고, 오염의 정도가 낮은 오염물은 세척수의 분사압력에 의해 식기에서 분해하여 탈리해 내는 구간이므로 정도 낮은 오염물 분해 탈리단계라 한다.The section (B) is a section in which the heating water is continuously heated to maintain the proper temperature, and the contaminants of the tableware are continuously called, and the contaminants having a low degree of contamination are decomposed and desorbed from the tableware by the injection pressure of the wash water. It is referred to as decontamination desorption step.

상기 구간(C)은 구간(B)을 통과하므로 세제가 모두 용해되고, 세척수가 가장 적정한 온도로 유지되며, 오염물질이 이상적으로 불려진 상태여서 오염정도가 높은 오염물을 강한 세척수의 분사압력으로 분해하고 탈리시키는 구간이므로 정도 높은 오염물 분해 탈리단계라 한다.Since the section (C) passes through the section (B), all of the detergent is dissolved, the washing water is maintained at the most appropriate temperature, and the contaminants are ideally called to decompose the contaminants having a high degree of contamination by the strong spray water injection pressure. Since it is a section for desorption, it is called a decontamination desorption step with a high degree of accuracy.

따라서, 상기 구간(A)은 세척요건의 준비단계로 볼 수 있기 때문에 식기가 세척되는 효율에는 지장을 주지 않으므로, 모터(5)의 회전수를 2500rpm 정도로 한다. 구간(B)은 세척요건의 준비를 계속 하고, 이 단계 수행중 오염 정도가 낮은 오염물 분해 탈리단계로 볼 수 있기 때문에 구간(A)에 비해 모터(5)의 회전수를 2800rpm 정도로 높인다.Therefore, since the section (A) can be seen as a preparation step of the washing requirements, the efficiency of washing the dishes is not impeded, so the rotation speed of the motor 5 is about 2500 rpm. Section (B) continues the preparation of the cleaning requirements, and during this step can be seen as a contaminant decomposition desorption step of low pollution degree during this step to increase the rotational speed of the motor (5) about 2800rpm compared to the section (A).

그리고, 상기 구간(C)은 구간(A)과 구간(B)을 거쳐 최상의 세척요건이 만족된 상태이기 때문에 노즐(4)에서의 세척수 분사압력이 최대가 되도록 하여 오염 정도가 심한 오염물 분해 탈리단계로 볼 수 있기 때문에 모터(5)의 회전수를 3300rpm 정도로 높이는 것이다.In addition, since the section C is in a state in which the best washing requirements are satisfied through the sections A and B, the cleaning water injection pressure at the nozzle 4 is maximized to decontaminate and remove the contaminants with severe contamination. Since the rotation speed of the motor 5 can be increased to about 3300 rpm.

상기 각 구간별 동작시간은 세척수 분사시간을 기준으로 가정했을 때 구간(A)은 대략 5분 까지이며, 구간(B)은 대략 5분에서 10분 까지이고, 구간(C)은 대략 10분에서 15분 사이로 설정함이 바람직하다.Assuming that the operation time for each section is based on the washing water injection time, section A is approximately 5 minutes, section B is approximately 5 to 10 minutes, and section C is approximately 10 minutes It is preferable to set it for 15 minutes.

위에서 설명한 구동방법은 단지 본 발명에 의한 일 실시예일 뿐이며, 예로써 펌프와 모터를 실린더 장치등으로 기능변환 시키거나 세척수 분사구간을 상기된 3구간 이상의 구간으로 구분한 것 등의 변환은 본 발명의 범위에 포함되어야 할 것이다.The above-described driving method is merely one embodiment of the present invention, and for example, the conversion of the pump and motor into a cylinder device or the like, or the division of the washing water spraying section into three or more sections described above, may be performed. It should be included in the scope.

이상에서 설명된 것과 같이 본 발명은, 세척펌프가 단계적으로 높아지는 압력을 갖도록 하여, 펌프를 구동시키는 동력 발생수단인 모터에 의한 소음발생 및 전력의 소모를 감소시킴으로써, 제품의 신뢰도 향상과 이에 따른 타사와의 제품경쟁에서 우위를 확보할 수 있는 효과가 있다.As described above, the present invention, by the washing pump has a step-increasing pressure, by reducing the noise generation and power consumption by the motor as a power generating means for driving the pump, thereby improving the reliability of the product and accordingly There is an effect that can secure an advantage in the competition with the product.
