Guide pipe 161 connected to the) is coupled.

이러한 구성에 의하여, 스핀바스켓(119)내에 세탁물이 수용되고 세탁코스가 선택되면, 도시 않은 제어부는 터브(115)내로 세탁수가 공급되도록 급수밸브(145)를 제어한다. 세탁코스에 따라 해당 급수밸브(145)가 유로를 개방하게 되면 세탁수는 해당 공급관(143)을 따라 급수부(112)로 유입된다. 급수부(112)내로 유입된 세탁수는 하향개구된 다수의 분사공을 통하여 세제통(109)의 해당 세제수용영역내로 분사되어 세제수용영역내에 수용된 세제와 혼합되어 안내부(159) 및 안내관(161)을 통하여 터브(115)내로 유입되게 된다.By this configuration, when the laundry is accommodated in the spin basket 119 and the washing course is selected, the controller (not shown) controls the water supply valve 145 so that the washing water is supplied into the tub 115. When the water supply valve 145 opens the flow path according to the washing course, the washing water flows into the water supply 112 along the supply pipe 143. The washing water introduced into the water supply unit 112 is injected into the corresponding detergent receiving area of the detergent container 109 through a plurality of downwardly-opened injection holes, mixed with the detergent contained in the detergent receiving area, and the guide part 159 and the guide tube ( It is introduced into the tub 115 through 161.

그런데, 이러한 종래의 세탁기에 있어서는, 세탁수와 함께 터브내로 유입된 세제가 충분히 용해되지 않은 상태에서 배수관과 터브의 저부영역에 잔류하게 된다. 이에 따라, 급수완료후 스핀바스켓의 정역회전구동에 의한 세탁행정진행시 세제의 실질농도가 저하되게 되어 세탁이 미흡하게 되는 문제점이 있다.By the way, in such a conventional washing machine, the detergent flowing into the tub together with the wash water remains in the drainage pipe and the bottom region of the tub without being sufficiently dissolved. Accordingly, after the water supply is completed, the actual concentration of the detergent is lowered when the washing operation is progressed by the forward and backward rotation driving of the spin basket, thereby causing insufficient washing.

따라서, 본 발명의 목적은, 세제가 적절히 용해될 수 있도록하여 세탁효과를 향상시킬 수 있는 세탁기 및 그 제어방법을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a washing machine and a method of controlling the same, which can improve the washing effect by allowing the detergent to be properly dissolved.

도 3은 도 1의 세탁기의 제어블럭도이고, 도 4는 본 발명에 따른 세탁기의 제어방법을 설명하기 위한 흐름도이다. 이들 도면에 도시된 바와 같이, 세탁프로그램이 내장된 마이컴 등을 포함하는 제어부(81)에는 터브(15)내의 세탁수량을 감지하도록 마련된 수위감지센서(85)가 연결되어 있으며, 제어부(81)는 수위감지센서(85)로부터의 감지신호를 수령하여 기 설정된 설정압력값을 상호 비교판단하는 비교판단부(83)를 포함한다. 그리고, 제어부(81)에는 세탁수의 유동을 제어할 수 있도록 제1 내지 제5급수밸브(71~75)가 각각 부속되어 있다.3 is a control block diagram of the washing machine of Figure 1, Figure 4 is a flow chart for explaining a control method of the washing machine according to the present invention. As shown in these figures, the control unit 81 including a microcomputer with a built-in laundry program is connected to a water level sensor 85 provided to detect the amount of washing in the tub 15, the control unit 81 And a comparison determination unit 83 which receives the detection signal from the water level detection sensor 85 and compares the predetermined set pressure value with each other. The control unit 81 is provided with first to fifth water supply valves 71 to 75 so as to control the flow of the wash water.

이러한 구성에 의하여, 스핀바스켓(19)내에 세탁물이 수용되고 세탁코스가 선택되면, 제어부(81)는 터브(15)내로 세탁수(여기서는 냉수를 사용한 세탁의 경우를 예를 들어 설명함)가 공급되도록 제5급수밸브(75)를 제어한다(S10). 제5급수밸브(75)가 개방되어 제2연결관(64)을 통하여 세탁수가 터브(15)내에 공급되면, 제어부(81)는 수위감지센서(85)를 제어하여 수위를 감지하도록 한다(S20).According to this configuration, when the laundry is accommodated in the spin basket 19 and the washing course is selected, the control unit 81 supplies the washing water (here, for example, the case of washing using cold water) into the tub 15. The fifth water supply valve 75 is controlled to be made (S10). When the fifth water supply valve 75 is opened and the washing water is supplied into the tub 15 through the second connecting pipe 64, the controller 81 controls the water level sensor 85 to detect the water level (S20). ).

비교판단부(83)에 의해 수위감지센서(85)로부터의 수위감지값이 기 설정된 제1설정압력값이상인 것으로 판단되면(S30), 제어부(81)는 제5급수밸브(75)를 차단하고(S40), 제3급수밸브(73)가 개방되도록 한다(S50). 제3급수밸브(73)가 개방되면 제3공급관(55)을 통해 급수부(12)로 유입된 세탁수는 세제수용영역으로 분사되어 세제와 함께 터브(15)내로 유입되게 된다.If it is determined by the comparison determination unit 83 that the water level detection value from the water level detection sensor 85 is equal to or greater than the preset first set pressure value (S30), the controller 81 shuts off the fifth water supply valve 75. (S40), the third water supply valve 73 is to be opened (S50). When the third water supply valve 73 is opened, the washing water introduced into the water supply unit 12 through the third supply pipe 55 is injected into the detergent receiving area and introduced into the tub 15 together with the detergent.

제3공급관(55)을 통해 세탁수가 터브(15)내로 소정 공급되면, 제어부(81)는 수위감지센서(85)를 제어하여 수위를 감지하도록 한다(S60). 수위감지값이 소정의 제2설정압력값이상이면(S70), 유로가 차단되도록 제3급수밸브(73)를제어한다(S80).When the washing water is supplied into the tub 15 through the third supply pipe 55, the controller 81 controls the water level sensor 85 to detect the water level (S60). If the water level detection value is equal to or greater than the predetermined second set pressure value (S70), the third water supply valve 73 is controlled to block the flow path (S80).

전술 및 도시한 실시예에서는, 냉수에 의한 세탁을 예를 들어 설명하고 있지만, 냉수와 온수가 적절히 혼합되도록 제4 및 제5급수밸브를 적절히 조절할 수 있음은 물론이다.In the above-described and illustrated embodiments, washing with cold water has been described as an example, but it is a matter of course that the fourth and fifth water supply valves can be properly adjusted so that cold water and hot water are properly mixed.

이상 설명한 바와 같이, 본 발명에 따르면, 터브내에 세탁수를 소정이상 공급되도록 한 상태에서 세제를 투입되도록 함으로써, 세제가 터브의 저부영역으로 침하되던 종래와는 달리, 세제가 세탁수에 적절히 용해될 수 있도록하여 세탁효과를 향상시킬 수 있는 세탁기 및 세탁기의 제어방법이 제공된다.As described above, according to the present invention, the detergent is introduced into the tub so that the detergent is introduced into the tub, so that the detergent may be properly dissolved in the wash water, unlike the conventional case in which the detergent is submerged in the bottom region of the tub. It is possible to provide a washing machine and a control method of the washing machine to improve the washing effect.
