Description

세탁기{Washing machine}Washing machine

본 발명은 세탁기에 관한 것으로서, 더 상세하게는 기기 내로 유입되는 냉수 또는 온수의 양을 자유자재로 조절할 수 있음과 함께 필요에 따라 기기 내로 유입되는 세탁수의 온도를 가변시킬 수 있는 세탁기에 관한 것이다.The present invention relates to a washing machine, and more particularly, to a washing machine capable of freely adjusting the amount of cold water or hot water flowing into the device, and varying the temperature of the washing water flowing into the device as needed. .

일반적으로, 세탁기는, 세탁물에 묻은 때나 더러운 물질을 화학적인 분해작용과 기계적인 충격작용에 의해 제거하는 기기로서, 도 1에 도시된 바와 같이, 본체(1)와, 상기 본체 내에 댐퍼에 의해 지지된 외조(2)와, 상기 외조 내에 회전 가능하게 설치되며 세탁물을 넣을 수 있는 원통형상의 내조(3)와, 상기 내조의 저면에 축결합되어 상기 내조를 회전시키는 구동부(4)로 크게 이루어진다.In general, a washing machine is a device that removes dirt or dirty material from laundry by chemical decomposition and mechanical impact. As shown in FIG. 1, the washing machine is supported by a main body 1 and a damper in the main body. It consists of a large outer tub 2, a cylindrical inner tub 3 rotatably installed in the outer tub and into which laundry can be put, and a driving unit 4 axially coupled to the bottom of the inner tub to rotate the inner tub.

이와 더불어, 상기 외조(2)의 하단에 일단이 연결되고 타단이 외조의 상단에 구비되는 공압관(6)과, 상기 공압관의 상단에 구비되어 외조(2) 내에 채워지는 세탁수 높이에 따라 주파수가 변화되면서 수위를 감지하는 수위센서(7)가 포함되어 이루어진다.In addition, one end is connected to the lower end of the outer tub (2) and the other end is provided on the upper end of the outer tub, and provided with the upper end of the pneumatic tube is filled in the outer tub (2) in accordance with the height The water level sensor 7 which detects the water level as the frequency is changed is included.

따라서, 사용자가 상기 내조(3)에 세탁하고자 하는 세탁물을 넣고 세제통에 세제를 넣은 상태에서 제어부에 구비된 세탁모드를 선택하면, 내조의 회전에 의해 세탁행정-헹굼행정-탈수행정이 연속적으로 이루어지면서 세탁이 진행되게 된다.Therefore, when the user puts the laundry to be washed in the inner tank 3 and selects the washing mode provided in the control unit while the detergent is put in the detergent container, the washing stroke-rinsing stroke-dehydrating stroke is continuously made by the rotation of the inner tank. Washing will proceed as you build.

특히, 세탁행정 또는 헹굼행정시, 외조(2) 내로 세탁수가 공급되게 되고 적정수위 만큼 채워지고 나면 수위센서(7) 및 제어부(미도시)에 의해 급수가 완료되게 된다.In particular, when washing or rinsing, washing water is supplied into the outer tank 2 and filled with the appropriate level, and the water supply is completed by the water level sensor 7 and a controller (not shown).

한편, 상술한 수위센서를 보다 구체적으로 살펴보면 다음과 같다.On the other hand, look at the above-described water level sensor in more detail as follows.

외조(2) 내에 세탁수가 공급되면, 공압관(6)에도 세탁수가 차오르면서 공압관의 공기압을 상승시키게 된다. 그리고, 상승된 공기압은 수위센서(7)의 다이어프램(미도시)을 부풀리게 되고, 이에 따라 수위센서의 코아(미도시)와 코일보빈(미도시)이 서로 상대변위를 일으키게된다.When the wash water is supplied into the outer tub 2, the washing water also rises in the pneumatic pipe 6, thereby raising the air pressure of the pneumatic pipe. In addition, the increased air pressure inflates the diaphragm (not shown) of the water level sensor 7, thereby causing a relative displacement between the core (not shown) and the coil bobbin (not shown) of the water level sensor.

그리고 상기 상대변위에 의해 발생된 자속밀도가 높아지게되고, 그에 따라 인덕턴스값이 상승하여 결국 상기 수위센서(7)의 주파수값이 줄어드는 원리를 이용하여 수위를 감지하게 된다.In addition, the magnetic flux density generated by the relative displacement is increased, thereby increasing the inductance value and finally detecting the water level by using the principle that the frequency value of the water level sensor 7 decreases.

하지만, 상기와 같이 이루어진 세탁기는 다음과 같은 문제가 있었다.However, the washing machine made as described above had the following problems.

첫째, 상기 수위센서(7)는, 외조(2) 내에 공급되는 세탁수량을 검출하는 것이 아니라 상술한 바와 같이 외조 내에 차오르는 수위를 검출하는 것임 따라, 10리터 또는 20리터 등 특정 수량을 요구하는 세탁시 한계가 있었다.First, the water level sensor 7 does not detect the amount of washing water supplied in the outer tank 2, but rather detects the level of water rising in the outer tank as described above. Thus, washing requiring a specific quantity such as 10 liters or 20 liters is required. There was a city limit.

둘째, 외조(2)로 공급되는 온수 및 냉수의 양을 조절할 수 없기 때문에 세탁수의 온도를 특정온도로 만드는데 문제가 있었다.Second, there is a problem in making the temperature of the wash water to a specific temperature because it can not control the amount of hot and cold water supplied to the outer tank (2).

상술한 문제점을 해결하기 위하여, 본 발명의 목적은, 기기 내로 유입되는 냉수 또는 온수의 양을 자유자재로 조절할 수 있음과 함께 필요에 따라 기기 내로 유입되는 세탁수의 온도를 가변시킬 수 있는 세탁기를 제공하는데 있다.In order to solve the above problems, an object of the present invention is to provide a washing machine capable of freely adjusting the amount of cold water or hot water flowing into the device and varying the temperature of the washing water flowing into the device as needed. To provide.

본 발명에 따른 세탁기는, 도 2에 나타난 바와 같이, 외조(2)로 냉수를 안내하는 냉수공급관(10)과 외조로 온수를 안내하는 온수공급관(110)을 갖는 세탁기에 있어서, 상기 냉수공급관(10)에 구비되어 상기 외조(2)로 유입되는 냉수의 양을 검출하는 냉수용 유량계(20)와, 상기 냉수공급관에 구비되어 상기 냉수용 유량계에서 검출된 냉수량에 따라 상기 냉수의 공급을 차단시키는 냉수용 밸브(30)와, 상기 온수공급관에 구비되어 상기 외조로 유입되는 온수의 양을 검출하는 온수용 유량계(120)와, 상기 온수공급관에 구비되어 상기 온수용 유량계에서 검출된 온수량에 따라 상기 온수의 공급을 차단시키는 온수용 밸브(130)와, 상기 냉수용 유량계 및 상기 온수용 유량계의 검출신호에 따라 상기 냉수용 밸브 및 온수용 밸브를 제어하여 상기 외조의 세탁수 온도를 설정온도로 유지시키는 제어부(50)가 포함되어 이루어진다.Washing machine according to the invention, as shown in Figure 2, in the washing machine having a cold water supply pipe 10 for guiding cold water to the outer tank (2) and hot water supply pipe 110 for guiding hot water to the outer tank, the cold water supply pipe ( 10) is provided in the cold water flow meter 20 for detecting the amount of cold water flowing into the outer tank (2), and is provided in the cold water supply pipe to block the supply of the cold water in accordance with the amount of cold water detected by the cold water flow meter To the cold water valve 30, the hot water flow meter 120 for detecting the amount of hot water introduced into the hot tub, and the hot water flow rate provided in the hot water supply pipe to detect the amount of hot water. According to the detection signal of the hot water valve 130 and the cold water flow meter and the hot water flow meter to block the supply of hot water to control the cold water valve and the hot water valve to adjust the washing water temperature of the tub. A control unit 50 is maintained to maintain the set temperature.

이하, 본 발명에 따른 세탁기의 동작을 구체적으로 설명하면 다음과 같다.Hereinafter, the operation of the washing machine according to the present invention will be described in detail.

세탁행정 또는 행굼행정이 시작되어 급수가 진행되면 냉수는 냉수공급관(10)을 따라 유동하고 온수는 온수공급관(110)을 따라 유동하면서 각각 냉수용 유량계(20) 및 온수용 유량계(120)를 거친 후 외조(2)로 공급되게 된다.Cold water flows along the cold water supply pipe 10 and the hot water flows along the hot water supply pipe 110 when the washing stroke or the rinsing stroke starts and the water flows through the cold water flowmeter 20 and the hot water flowmeter 120, respectively. It is then supplied to the outer tank (2).

이때, 냉수용 유량계(20) 및 온수용 유량계(120)에서는 각각 수량을 검출하게 되고 검출된 신호는 리드선(21, 121)을 따라 제어부(50)에 인가되어 설정된 세탁수량 및 설정된 온도에 해당되게 되면 제어부에 의해 개별적으로 냉수용 밸브(30) 및 온수용 밸브(130)를 차단시켜 급수를 종료시키게 된다.At this time, the cold water flow rate meter 20 and the hot water flow rate meter 120 detects the quantity, respectively, and the detected signal is applied to the controller 50 along the lead wires 21 and 121 to correspond to the set washing amount and the set temperature. When the control unit individually blocks the cold water valve 30 and the hot water valve 130 to terminate the water supply.

한편, 온수의 온도가 정해지지 않을 경우, 보다 바람직하게 세탁수의 온도를 특정시키기 위해서는, 외조(2) 내의 수온을 감지하여 상기 제어부(50)에 감지신호를 인가시키기 위한 온도센서(미도시)가 상기 외조(2) 내에 더 구비됨이 바람직하다.On the other hand, when the temperature of the hot water is not determined, in order to more specifically specify the temperature of the washing water, a temperature sensor (not shown) for sensing the water temperature in the outer tank 2 and applying a detection signal to the controller 50 is provided. It is preferable that the outer tank 2 is further provided.

즉, 온수의 온도가 정해지지 않게 되면, 냉수의 양과 온수의 양만을 가지고 세탁수의 온도를 특정시키기가 곤란하므로, 외조(2) 내에 구비된 별도의 온도센서를 가지고 외조의 수온을 계속 측정하면서 측정된 감지신호를 제어부(50)에 보내 냉수용 밸브(30) 및 온수용 밸브(130)를 적절히 제어하면서 세탁수의 온도를 설정된 온도로 만들게 된다.That is, if the temperature of the hot water is not determined, it is difficult to specify the temperature of the washing water with only the amount of cold water and the amount of hot water, so that the measurement is performed while continuously measuring the water temperature of the outer tank with a separate temperature sensor provided in the outer tank 2. By sending the detected signal to the controller 50 to control the cold water valve 30 and the valve for hot water 130 to make the temperature of the wash water to the set temperature.

즉, 온수의 온도가 정해지지 않게 되면, 냉수의 양과 온수의 양만을 가지고 세탁수의 온도를 특정시키기가 곤란하므로, 온수용 유량계(120) 내에 구비된 별도의 온도센서를 가지고 온수의 온도를 계속 측정하면서 측정된 감지신호를 제어부(50)에 보내 냉수용 밸브(30) 및 온수용 밸브(130)를 적절히 제어하면서 세탁수의 온도를 설정된 온도로 만들게 된다.That is, if the temperature of the hot water is not determined, it is difficult to specify the temperature of the wash water with only the amount of cold water and the amount of hot water, so that the temperature of the hot water is continuously measured with a separate temperature sensor provided in the hot water flowmeter 120. While sending the measured detection signal to the control unit 50 to properly control the cold water valve 30 and the hot water valve 130 to make the temperature of the wash water to a set temperature.

따라서, 본 발명에 따른 유량계가 구비된 세탁기를 제공함에 따라, 10리터, 20리터 등의 특정된 세탁수량을 요구하는 세탁시, 보다 정확한 양의 세탁수를 공급할 수 있게 된다. 그리고, 필요에 따라 외조 내에 채워지는 세탁수의 온도 또한 특정시킬 수 있어 보다 바람직한 세탁을 수행할 수 있게 된다.Therefore, by providing a washing machine equipped with a flow meter according to the present invention, it is possible to supply a more accurate amount of washing water when washing requires a specific washing water amount, such as 10 liters, 20 liters. And, if necessary, the temperature of the wash water filled in the outer tank can also be specified, so that more preferable washing can be performed.
