일반적으로 세탁기는 세제의 유화 작용 및 펄세이터(pulsator)의 회전에 따른 수류의 마찰작용 및 펄세이터가 세탁물에 가하는 충격작용 등을 이용하여 의복, 침구 등에 부착된 각종 오염 물질을 제거하는 작용을 수행하고, 센서에 의해 세탁물의 양과 종류를 감지하여 세탁방법을 자동으로 설정할 뿐 아니라 세탁수를 세탁물의 양과 종류에 따라 적절한 수위로 급수 후 마이컴의 제어에 따라 세탁을 수행한다.In general, a washing machine performs a function of removing various contaminants attached to clothes, bedding, etc. by using an emulsification action of a detergent and a friction action of water flow due to the rotation of a pulsator, and an impact action applied to the laundry by the pulsator. In addition, the sensor detects the amount and type of laundry and automatically sets the washing method. The washing water is supplied to the appropriate level according to the amount and type of laundry, and then washing is performed under the control of the microcomputer.

And a clutch 12 and a motor 14 mounted on the washing tub 6 or the pulsator 8 to transmit driving power, and installed on an upper side of the washing tub 6 to wash the washing water together with the detergent. A water supply valve assembly 18 including a detergent box assembly 16 and a water supply valve 18a to be supplied, and a drain valve installed at a lower portion of the dehydration tank 4 to drain the washing water inside the washing tank 6. A drain valve assembly 20 including the 20a, the clutch 12 and the motor ( 14) and a microcomputer (not shown) for controlling the operation of the washing machine by controlling the supply / drain valves (18a, 20a) and the like.

여기서, 상기 세제박스 어셈블리(16)는 세제가 저장되는 세제박스(16a)와, 상기 세제박스(16a)가 탈착되도록 상기 케이스(2)의 상부에 고정되는 세제박스 하우징(16b)으로 구성되며, 상기 급수밸브 어셈블리(18)는 상기 급수밸브(18a)가 온되면 세제와 함께 세탁수가 동시에 상기 세탁조(6) 내부로 공급되도록 상기 세제박스 하우징(18b)과 연결되도록 설치된다.Here, the detergent box assembly 16 is composed of a detergent box 16a in which detergent is stored, and a detergent box housing 16b fixed to an upper portion of the case 2 so that the detergent box 16a is detachable. The water supply valve assembly 18 is installed to be connected to the detergent box housing 18b such that when the water supply valve 18a is turned on, washing water is simultaneously supplied into the washing tub 6 together with detergent.

The purpose is to provide a washing course determination method of a washing machine.

상기한 과제를 해결하기 위한 본 발명에 따른 세탁기의 세탁코스 결정방법은 세탁조 일측에 부착된 온도센서 및 전극센서가 잠기도록 세탁수 및 세제가 투입되는 제1단계와, 상기 제1단계의 온도센서에 의해 세탁수의 수온이 측정된 다음 측정된 수온에 따라 세제량 회귀식이 설정되는 제2단계와, 상기 제1단계의 전극센서에 의해 측정된 세탁수의 전도도에 따라 전극센서의 고장여부가 판단되고, 상기 전도도 및 세제량 회귀식으로부터 투입되는 세제량이 판단되는 제3단계와, 상기 제3단계의 판단된 세제량에 따라 세탁패턴이 설정된 다음 설정된 세탁패턴에 따라 세탁 운전이 수행되는 제4단계로 이루어진다.Washing course determination method of the washing machine according to the present invention for solving the above problems is the first step of the washing water and detergent is injected so that the temperature sensor and the electrode sensor attached to one side of the washing tank, and the temperature sensor of the first step After the water temperature of the washing water is measured by the second step of setting the detergent amount regression equation according to the measured water temperature, and whether or not the electrode sensor is determined according to the conductivity of the wash water measured by the electrode sensor of the first step And a third step of determining the amount of detergent inputted from the conductivity and detergent amount regression equation, and a fourth step of washing operation being set according to the set washing pattern according to the determined amount of detergent in the third step.

이하, 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 세탁기가 도시된 측단면도이고, 도 3은 본 발명에 따른 세탁기의 세탁코스 결정방법이 도시된 순서도이며, 도 4는 본 발명에 따른 세탁기의 전도도 및 수온에 따른 세제량 회귀식이 도시된 그래프이다.2 is a side cross-sectional view showing a washing machine according to the present invention, Figure 3 is a flow chart illustrating a washing course determination method of the washing machine according to the invention, Figure 4 is a detergent amount regression according to the conductivity and water temperature of the washing machine according to the present invention The equation is a graph.

본 발명에 따른 세탁기의 세탁코스 결정방법은 도 2와 도 3에 도시된 바와 같이 먼저 급수밸브(68a)가 온되어 세탁수가 세탁조(56) 또는 탈수조(54)에 부착된 온도센서(72a) 및 전극센서(72b)가 잠기도록 세제 및 세탁수가 급수된다.(S1 참조)In the washing course determining method of the washing machine according to the present invention, as shown in FIGS. 2 and 3, the water supply valve 68a is turned on so that the washing water is attached to the washing tank 56 or the dehydrating tank 54. And detergent and wash water are supplied so that the electrode sensor 72b is locked (see S1).

여기서, 상기 급수밸브 어셈블리(68)는 상기 세제박스 어셈블리(66)와 연결되도록 설치되되, 구체적으로 세탁수는 세제박스 하우징(66a)을 통하여 세제박스(66b)에 저장된 세제 측으로 분사되어 세제와 함께 상기 세탁조(56) 및 탈수조(54) 내부로 급수된다.Here, the water supply valve assembly 68 is installed to be connected to the detergent box assembly 66, in particular, the washing water is sprayed to the detergent side stored in the detergent box 66b through the detergent box housing 66a together with the detergent. Water is supplied to the washing tank 56 and the dehydration tank 54.

다음, 제2단계는 상기 제1단계에서 세탁수 및 세제가 상기 세탁조(56) 및 탈수조(54) 내부로 공급되면, 상기 온도센서(72a)에 의해 세탁수의 수온(T)이 감지된다.(S2 참조)Next, when the washing water and the detergent are supplied into the washing tank 56 and the dehydrating tank 54 in the first step, the water temperature T of the washing water is sensed by the temperature sensor 72a. (See S2)

다음, 제3단계는 상기 제2단계에서 측정된 수온(T)에 따라 세제량 회귀식이 설정된다.(S3 참조)Next, in the third step, the detergent amount regression equation is set according to the water temperature T measured in the second step.

이때, 상기 세제량 회귀식은 다수개의 특정 온도에 대해 기설정되어 마이컴(미도시)에 내장되어 있다.In this case, the detergent amount regression equation is preset for a plurality of specific temperatures and built in the microcomputer (not shown).

여기서, 상기 세탁수의 수온(T)에 따른 세제량 회귀식 설정방법을 좀더 구체적으로 살펴보면, 도 4 및 도 6에서 보는 바와 같이 먼저 세탁수의 수온(T)이 측정된다.(S11 참조)Here, looking at the detergent amount regression setting method according to the water temperature (T) of the washing water in more detail, as shown in Figures 4 and 6, the water temperature (T) of the washing water is first measured (see S11).

다음, 제2과정은 상기 제1과정에서 측정된 수온(T)이 제1설정온도(T1) 이상인 경우 세제량 회귀식D가 설정된다.(S12,S13 참조)Next, in the second process, the detergent amount regression equation D is set when the water temperature T measured in the first process is equal to or greater than the first set temperature T1. (See S12 and S13.)

다음, 제3과정은 상기 제2과정에서 측정 수온(T)이 상기 제1설정온도(T1) 미만이고, 상기 제2설정온도(T2) 이상인 경우 세제량 회귀식C가 설정된다.(S14,S15 참조)Next, in the third process, the detergent amount regression equation C is set when the measured water temperature T is less than the first set temperature T1 and is greater than or equal to the second set temperature T2 in the second process. (S14, S15 Reference)

다음, 제4과정은 상기 제3과정에서 측정 수온(T)이 상기 제2설정온도(T2) 미만이고, 상기 제3설정온도(T3) 이상인 경우 세제량 회귀식B가 설정된다.(S16,S17 참조)Next, in the fourth process, the detergent amount regression type B is set when the measured water temperature T is less than the second set temperature T2 and is greater than or equal to the third set temperature T3 in the third process. (S16, S17 Reference)

다음, 제5과정은 상기 제4과정에서 측정 수온(T)이 상기 제3설정온도(T3) 미만인 경우 세제량 회귀식A가 설정된다.(S18 참조)Next, in the fifth process, the detergent amount regression equation A is set when the measured water temperature T is less than the third set temperature T3 in the fourth process (see S18).

한편, 제4단계는 상기 제1단계에서 세탁수 및 세제가 상기 세탁조(56) 및 탈수조(54) 내부로 공급되면, 상기 전극센서(72b)에 의해 세탁수의 전도도(R)가 감지된다.(S4 참조)Meanwhile, in the fourth step, when the washing water and the detergent are supplied into the washing tank 56 and the dehydrating tank 54 in the first step, the conductivity R of the washing water is sensed by the electrode sensor 72b. (See S4)

이때, 상기 전도도(R)는 세제 성분이 이온화됨으로 세제가 과다하게 투입될수록 그 값이 커지게 되는데, 상기 전도도(R)를 표시하는 회로 구성에 따라 그 값이 커지게 도시될 수도 있고, 그 값이 작게 도시될 수도 있다.At this time, the conductivity (R) is the value of the detergent component is ionized and the detergent is excessively increased as the value is increased, depending on the circuit configuration for displaying the conductivity (R) may be shown to be larger, the value This may be shown small.

그리고, 상기 전도도(R)는 수온(T)에 따라 그 값이 변화될 수 있으므로 세탁수는 전도도(R)와 수온(T)이 동시에 측정되며, 이와 같은 전도도(R) 및 수온(T)은 투입된 세제량 판단을 위한 기준이 된다.In addition, since the value of the conductivity (R) may change according to the water temperature (T), the conductivity of the wash water (R) and the water temperature (T) are simultaneously measured, and the conductivity (R) and the water temperature (T) are It is a standard for judging the amount of detergent injected.

다음, 제5단계는 상기 제4단계에서 측정된 전도도(R)에 따라 설정된 세제량 회귀식으로부터 투입된 세제량이 판단된다.(S5 참조)Next, in the fifth step, the amount of detergent injected from the detergent amount regression equation set according to the conductivity R measured in the fourth step is determined.

여기서, 세탁수의 전도도(R)에 따른 세제량 판단방법을 좀더 구체적으로 살펴보면, 도 5와 도 6에 도시된 바와 같이 세탁수의 전도도(R)가 측정된다.(S21 참조)Here, looking at the detergent amount determination method according to the conductivity (R) of the wash water in more detail, as shown in Figures 5 and 6, the conductivity (R) of the wash water is measured (see S21).

다음, 제2과정은 상기 제1과정에서 측정된 세탁수의 전도도(R)가 제1설정전도도(R1) 이상인 경우 상기 전극센서(72b) 고장으로 판단되고, 투입된 세제량이 표준 세제량으로 판단된다.(S22,S23,S24 참조)Next, in the second process, when the conductivity R of the wash water measured in the first process is greater than or equal to the first predetermined conductivity R1, the electrode sensor 72b is determined to be in failure, and the amount of detergent added is determined as the standard detergent amount. (See S22, S23, S24)

다음, 제3과정은 상기 제2과정에서 측정된 전도도(R)가 상기 제1설정전도도(R1) 미만이고, 상기 제2설정전도도(R2) 이상인 경우 투입된 세제량이 무세제로 판단된다.(S25,S26 참조)Next, in the third process, when the conductivity (R) measured in the second process is less than the first set conductivity (R1) and the second set conductivity (R2) or more, it is determined that the amount of detergent added is no detergent. See S26)

다음, 제4과정은 상기 제3과정에서 측정된 전도도(R)가 상기 제2설정전도도(R2) 미만이고, 상기 제3설정전도도(R3) 이상인 경우 투입된 세제량이 표준 세제량으로 판단된다.(S27,S28 참조)Next, in the fourth process, when the conductivity R measured in the third process is less than the second set conductivity R2 and is greater than or equal to the third set conductivity R3, the amount of detergent added is determined to be a standard detergent amount. , See S28)

다음, 제5과정은 상기 제4과정에서 측정된 전도도(R)가 상기 제3설정전도도(R3) 미만인 경우 투입된 세제량이 과다 세제량으로 판단된다.(S29 참조)Next, in the fifth process, when the conductivity R measured in the fourth process is less than the third set conductivity R3, it is determined that the amount of detergent added is excessive detergent amount (see S29).

다음, 제6단계는 상기 제5단계에서 판단된 세제량에 따라 세탁 패턴이 설정된다.(S6 참조)Next, in the sixth step, the washing pattern is set according to the amount of detergent determined in the fifth step.

여기서, 상기 세탁패턴은 투입된 세제량에 따라 비교적 세탁시간이 긴 반면 헹굼시간이 짧고 헹굼수위가 낮은 무세제 세탁패턴과, 세탁 및 헹굼시간과 헹굼수위가 세탁물의 포량에 대해 최적으로 설정되는 표준 세탁패턴과, 비교적 세탁시간이 짧은 반면 헹굼시간이 길고 헹굼수위가 높은 과다 세제 세탁패턴으로 나뉘어진다.Here, the washing pattern has a relatively long washing time according to the amount of detergent injected, while a short rinsing time and a low rinsing level, a detergent-free washing pattern, and a standard washing pattern in which washing and rinsing time and rinsing water level are optimally set for the amount of laundry. And, the washing time is relatively short, while the rinsing time is long, and the rinsing water level is divided into an excessive detergent washing pattern.

이때, 투입된 세제량이 무세제로 판단되는 경우 무세제 세탁패턴이 설정되고, 투입된 세제량이 표준 세제량으로 판단되는 경우 표준 세탁패턴이 설정되며, 투입된 세제량이 과다 세제량으로 판단되는 경우 과다 세제 세탁패턴으로 설정된다.At this time, if the detergent amount is determined to be detergent-free, the detergent-free washing pattern is set, and if the detergent amount is determined to be the standard detergent amount, the standard washing pattern is set, and if the detergent amount is determined to be the excess detergent amount, it is set as an excessive detergent washing pattern. .

다음, 상기 제7단계는 상기 제6단계에서 설정된 세탁패턴에 따라 세탁 운전이 수행된다.(S7 참조)Next, in the seventh step, the washing operation is performed according to the washing pattern set in the sixth step.

상기와 같이 구성되는 본 발명에 따른 세탁기의 세탁코스 결정방법은 온도센서와 전극센서에 의해 세탁수의 수온 및 전도도가 측정되고, 수온에 따라 설정된 세제량 회귀식으로부터 전도도에 따라 투입된 세제량이 판단되며, 투입된 세제량에 따라 설정된 최적의 세탁패턴으로 세탁 운전이 수행되도록 하기 때문에 세탁 성능이 향상될 뿐 아니라 물이나 전기 등의 에너지 낭비를 줄일 수 있는 이점이 있다. In the washing course determination method of the washing machine according to the present invention configured as described above, the water temperature and conductivity of the washing water are measured by a temperature sensor and an electrode sensor, and the amount of detergent injected according to the conductivity is determined from the detergent amount regression equation set according to the water temperature.
