Description
본 고안은 세탁기에 관한 것으로, 특히 설정된 수온에 적합하도록 온수밸브 및 냉수밸브의 개폐조절로 세탁하려는 세탁물의 세탁온도를 조절하는 세탁기의 수온 조절장치에 관한 것이다.The present invention relates to a washing machine, and more particularly, to a water temperature control apparatus for controlling the washing temperature of the laundry to be washed by the opening and closing control of the hot water valve and the cold water valve to suit the set water temperature.
세탁기는 세탁조에 세탁물을 투입한 후에 일정량의 물을 유입시키고, 설정된 세탁코스를 선택하여 동작버튼을 누르면, 설정된 시간동안 세탁기능이 수행되는 것으로, 방식에 따라 수동식 및 반자동식과 전자동식으로 나뉘어지고, 세탁용량에 따라 그 크기가 달라진다. 또한, 세탁기는 기능상으로 대별되는데, 점진적으로 각종의 세탁기능이 추가되거나 퍼지용 집적회로를 통해 완전자동화가 이루어지는 추세이다.After the washing machine is put laundry into the washing tank, a certain amount of water is introduced and the washing course is selected by pressing the operation button. The washing function is performed for the set time. The washing machine is divided into manual, semi-automatic and fully automatic according to the method. The size depends on the laundry capacity. In addition, the washing machine is roughly classified as a function, and gradually, various washing functions are gradually added or fully automated through an integrated circuit for purging.
종래의 세탁기에서 세탁조에 투입되는 세탁물의 양에 따라 세탁에 필요한 물의 양은 각각 정해져 있었다. 즉, 세탁기의 사용자가 세탁량에 따라 고(高), 중(中) 및 저(低) 등으로 구분하여 설정하면, 세탁기는 제어용 마이크로프로세서에서 입력된 세탁량을 판단함으로써, 세탁조로 투입되는 세탁량에 비례하는 양의 물을 유입시켜 세탁을 할 수 있었다. 또한, 세탁물의 종류에 따라 온수를 투입할 것인지 또는 냉수를 투입할 것인지에 관하여도 사용자는 선택을 하여야 했다.In the conventional washing machine, the amount of water required for washing is determined by the amount of laundry to be put into the washing tank. That is, if the user of the washing machine is set to high, medium and low according to the washing amount, the washing machine determines the washing amount input from the control microprocessor, and is proportional to the washing amount put into the washing tank. It was able to wash by inflowing the amount of water. In addition, according to the type of laundry, the user had to choose whether to add hot water or cold water.
그러나, 종래의 세탁기의 경우에는 세탁조내로 온수 또는 냉수만을 선택적으로 유입시켜 세탁을 할 수밖에 없었으므로 사용자가 세탁하려는 세탁물에 대한 세탁온도를 임의로 설정하지 못하였다. 즉, 세탁조에 유입되는 온수나 냉수는 단순히 물의 온도범위에 상관없이 온수나 냉수를 유입시키는 온수 및 냉수호스와 온수 및 냉수밸브를 통해 세탁조에 물을 유입시키므로 온수나 냉수의 정확한 수온에 대해서는 그 판단기준이 없었다. 따라서, 온수 및 냉수를 세탁조로 유입시킬 때에 온수호스를 보일러와 같이 더운 물을 공급하는 온수공급용 꼭지에 꽂아 사용하였고, 냉수호스의 경우에도 수도꼭지 등에 직접 꽂아 냉수를 공급받아 사용하였다. 그러므로, 세탁조로 유입되는 온수에 대한 온도를 정확하게 인식하지 못할 경우에는 세탁물을 세탁할 때에 유입되는 온수에 의해 세탁물이 손상되는 문제가 있었다.However, in the conventional washing machine, since only the hot or cold water is selectively introduced into the washing tank to wash, the user cannot arbitrarily set the washing temperature for the laundry to be washed. In other words, the hot water or cold water flowing into the washing tank simply inputs the water into the washing tank through the hot and cold water hoses and the hot and cold water valves that introduce hot or cold water regardless of the temperature range. There was no standard. Therefore, when hot water and cold water were introduced into the washing tank, the hot water hose was plugged into a hot water supply tap for supplying hot water such as a boiler, and the cold water hose was directly inserted into a faucet and used to receive cold water. Therefore, when the temperature of the hot water flowing into the washing tank is not accurately recognized, there is a problem that the laundry is damaged by the hot water introduced when washing the laundry.
본 고안은 상기와 같은 문제를 해결하기 위하여 안출한 것으로, 세탁기의 사용자가 세탁물의 종류에 따라 유입되는 물의 수온을 설정하여 입력시키면, 냉수 및 온수밸브의 개폐로 물의 온도를 조절시켜 설정된 온도의 물로 세탁물의 세탁효과를 배가시키는 세탁기의 수온 조절장치를 제공하기 위한 것이 목적이다.The present invention is devised to solve the above problems, when the user of the washing machine sets the water temperature of the incoming water according to the type of the laundry, input the water temperature by opening and closing the cold water and hot water valve to the water of the set temperature An object of the present invention is to provide a water temperature control device for a washing machine that doubles the washing effect of laundry.

이하, 첨부된 도면에 의거하여 본 고안에 관한 세탁기의 수온 조절장치를 살펴보면 다음과 같다.Hereinafter, looking at the water temperature control device of the washing machine according to the present invention based on the accompanying drawings.
도 1은 본 고안에 따른 세탁기의 수온 조절장치의 블록도로, 온도감지부(10)는 세탁조(30)의 내부일측에 장착되어 수온을 감지하는 것으로, 세탁을 위하여 세탁조(30)내로 유입되는 물의 온도를 일정온도까지 감지할 수 있는 감지범위를 갖는 온도센서가 사용된다.1 is a block diagram of the water temperature control device of the washing machine according to the present invention, the temperature sensing unit 10 is mounted on one side of the washing tank 30 to detect the water temperature, the water flowing into the washing tank 30 for washing A temperature sensor with a sensing range capable of detecting temperature up to a certain temperature is used.
온도설정부(16)는 사용자가 세탁물의 종류를 감안하여 제어패널의 일측에 구성된 키입력부를 조작시켜 수온을 설정시키는 것이다.The temperature setting unit 16 allows the user to set the water temperature by operating a key input unit configured at one side of the control panel in consideration of the type of laundry.
온도비교부(12)는 상기 온도설정부(16)에서 설정되어 입력된 신호와, 온도감지부(10)에서 감지한 온도를 비교하여 비교된 신호를 출력시키는 것이다.The temperature comparing unit 12 compares the signal set and input by the temperature setting unit 16 with the temperature sensed by the temperature detecting unit 10 and outputs the compared signal.
제어부(14)는 상기 온도감지부(10), 온도설정부(16) 및 온도비교부(12)로부터 입력된 온도에 관한 신호를 판단하여 내장된 프로그램이나 기준데이터와의 비교로 해당되는 제어신호를 출력시킨다.The controller 14 determines a signal related to the temperature input from the temperature sensing unit 10, the temperature setting unit 16, and the temperature comparing unit 12, and compares the control signal with a built-in program or reference data. Outputs
온수조절밸브(18)는 온수호스(19)의 일단에 구성되어 유입되는 온수를 상기 제어부(14)의 제어신호로 개폐시킨다. 냉수조절밸브(20)는 냉수호스(21)의 일단에 유입되는 냉수를 상기 제어부(14)의 제어신호로 개폐시키는 것이다.The hot water control valve 18 is configured to open and close the hot water introduced at one end of the hot water hose 19 by the control signal of the controller 14. The cold water control valve 20 opens and closes the cold water flowing into one end of the cold water hose 21 by the control signal of the controller 14.
이와 같이 구성된 본 고안에 관하여 작용을 상세하게 설명한다.The operation of the present invention configured as described above will be described in detail.
세탁기의 사용자가 세탁하려는 세탁물의 종류를 판단하여 세탁물의 세탁온도를 온도설정부(16)에 구성된 키입력부의 키입력으로 설정을 하면, 온도설정부(16)에서 설정된 온도에 관한 데이터는 각각 온도비교부(12) 및 제어부(14)로 입력된다. 온도설정부(16)에서 설정할 수 있는 온도는 일정의 단위 즉, 1℃간격이나 5℃간격 또는 10℃간격으로 설정되게 할 수 있다. 이는 온도감지부(10)에서 사용되는 온도센서의 감지범위에 따라 다를 수 있기 때문이다.When the user of the washing machine determines the type of the laundry to be washed, and sets the washing temperature of the laundry as the key input of the key input unit configured in the temperature setting unit 16, the data regarding the temperature set in the temperature setting unit 16 is respectively set to the temperature. It is input to the comparator 12 and the controller 14. The temperature that can be set by the temperature setting unit 16 may be set to a predetermined unit, that is, 1 ° C interval, 5 ° C interval, or 10 ° C interval. This is because it may vary depending on the detection range of the temperature sensor used in the temperature sensor 10.
세탁물의 세탁을 위하여 세제의 투입과 각종의 조건설정이 완료되고, 또, 상기 온도설정부(16)에서 온도설정이 완료되면, 사용자는 세탁기의 키입력부에 구성된 작동키를 입력시킨다. 작동키가 입력되면 제어부(14)는 세탁을 위한 물을 투입시키기 위하여 온수호스(19) 및 냉수호스(21)에 각각 구성된 온수조절밸브(18) 및 냉수조절밸브(20)를 개방시켜 온수 및 냉수를 유입시킨다. 이때, 제어부(14)는 설정된 온도에 따라 온수조절밸브(18) 및 냉수조절밸브(20)의 개폐정도를 달리할 수 있다. 즉, 설정온도가 높을 때에는 냉수조절밸브(20)보다 온수조절밸브(18)를 많이 개방시켜 온수가 더 많이 유입되게 하고, 설정온도가 낮을 때에는 온수조절밸브(18)보다 냉수조절밸브(20)를 많이 개방시켜 냉수가 많이 유입되게 한다.When the detergent is added and various conditions are set for washing the laundry, and the temperature is set in the temperature setting unit 16, the user inputs an operation key configured in the key input unit of the washing machine. When the operation key is input, the controller 14 opens the hot water control valve 18 and the cold water control valve 20 respectively configured in the hot water hose 19 and the cold water hose 21 to inject water for washing. Inflow of cold water. At this time, the controller 14 may vary the opening and closing degree of the hot water control valve 18 and the cold water control valve 20 according to the set temperature. That is, when the set temperature is high, the hot water control valve 18 is opened more than the cold water control valve 20 so that more hot water is introduced. When the set temperature is low, the cold water control valve 20 is higher than the hot water control valve 18. Open a lot of cold water to let a lot of inflow.
이때, 온수호스(19) 및 냉수호스(21)를 통해 유입되는 물은 세탁조(30)의 일측에 구비된 온도감지부(10)의 온도센서가 수온을 감지한다. 온도감지부(10)에서 감지한 온도에 관한 신호는 각각 온도비교부(12) 및 제어부(14)로 입력된다. 온도비교부(12)는 상기 온도설정부(16)로부터 설정되어 입력된 온도신호와 온도감지부(10)로부터 입력된 온도에 관한 신호를 비교하여 비교된 신호를 제어부(14)로 출력시킨다. 제어부(14)는 온도비교부(12)로부터 입력된 비교신호를 판단하여 온도설정부(16)에서 입력된 설정된 온도보다 온도감지부(10)에서 감지한 온도가 높을 때에는 온수조절밸브(18)를 일정비율로 잠그거나 냉수조절밸브(20)를 더 개방시켜 냉수의 유입속도를 높이도록 제어신호를 출력시킨다. 또한, 제어부(14)는 온도비교부(12)에서 입력된 비교신호와, 온도설정부(16)에서 설정된 온도에 관한 신호 및 온도감지부(10)에서 감지되어 입력된 온도신호를 각각 판단하여 온도설정부(16)에서 설정된 신호보다 온도감지부(10)에서 입력된 신호가 더 작으면, 제어부(14)는 각각 온수조절밸브(18) 및 냉수조절밸브(20)에 제어신호를 출력시켜 온수조절밸브(18)를 일정비율로 더 개방시키거나 냉수조절밸브(20)를 통해 유입되는 냉수의 유입속도를 줄인다.At this time, the water flowing through the hot water hose 19 and the cold water hose 21 is the temperature sensor of the temperature sensing unit 10 provided on one side of the washing tank 30 detects the water temperature. The signal related to the temperature detected by the temperature sensing unit 10 is input to the temperature comparing unit 12 and the control unit 14, respectively. The temperature comparison unit 12 compares the temperature signal set and input from the temperature setting unit 16 with the signal related to the temperature input from the temperature sensing unit 10 and outputs the compared signal to the control unit 14. The control unit 14 determines the comparison signal input from the temperature comparing unit 12 and when the temperature detected by the temperature sensing unit 10 is higher than the set temperature input by the temperature setting unit 16, the hot water control valve 18. To lock at a constant rate or to further open the cold water control valve 20 to output a control signal to increase the inflow rate of cold water. In addition, the controller 14 determines the comparison signal input from the temperature comparator 12, the signal related to the temperature set by the temperature setting unit 16, and the temperature signal detected and input by the temperature sensing unit 10, respectively. When the signal input from the temperature sensing unit 10 is smaller than the signal set by the temperature setting unit 16, the controller 14 outputs a control signal to the hot water control valve 18 and the cold water control valve 20, respectively. The hot water control valve 18 is further opened at a predetermined ratio or the inflow rate of cold water introduced through the cold water control valve 20 is reduced.
이와 같이 세탁조(30)내로 유입되는 온수 및 냉수의 비율은 온도설정부(16)에서 설정된 수온과 온도감지부(10)에서 감지한 수온이 일치할 때까지 제어부(14)는 계속 온수조절밸브(18) 및 냉수조절밸브(20)의 개폐정도를 제어하여 세탁조(30)내에는 온도설정부(16)에서 설정된 수온의 물이 채워지게 된다.As such, the ratio of the hot water and the cold water introduced into the washing tank 30 is controlled until the water temperature set by the temperature setting unit 16 and the water temperature detected by the temperature sensing unit 10 are consistent with each other. 18) by controlling the opening and closing degree of the cold water control valve 20 is filled in the water temperature of the water temperature set in the temperature setting section 16 in the washing tank (30).
세탁조(30)내로 설정된 양 및 수온의 물이 유입되면, 제어부(14)는 온수조절밸브(18) 및 냉수조절밸브(20)를 모두 잠그는 제어신호를 출력시키고, 세탁의 시작을 위한 제어신호를 구동모터나 별도의 구동장치로 출력시킨다.When water of the amount and water temperature set in the washing tank 30 flows in, the controller 14 outputs a control signal for locking both the hot water control valve 18 and the cold water control valve 20, and outputs a control signal for starting washing. Output to drive motor or separate drive device.
또한, 제어부(14)는 세탁이 시작되었을 때에는 온도비교부(12)의 신호를 무시하지만, 세탁행정이 완료되고, 헹굼이나 별도의 행정때에는 계속하여 유입되는 물에 대하여 설정된 수온을 유지시켜 준다.In addition, the control unit 14 ignores the signal of the temperature comparison unit 12 when the washing is started, but the washing operation is completed, and maintains the water temperature set for the water continuously flowing in the rinsing or a separate stroke.
이상에서 설명한 바와 같이, 본 고안은 세탁기내로 유입되는 세탁수의 수온을 사용자가 온도설정부에서 임의로 설정시키면, 온수호스 및 냉수호스에 구성된 온수밸브 및 냉수밸브의 개폐를 조절시켜 설정된 수온으로 세탁물을 세탁할 수 있도록 함으로써, 세탁기의 기능향상 및 세탁물의 손상을 최소화시킨 효과가 있다.As described above, according to the present invention, when the user sets the water temperature of the washing water flowing into the washing machine arbitrarily in the temperature setting unit, the laundry is heated at the set water temperature by controlling the opening and closing of the hot water valve and the cold water valve configured in the hot water hose and the cold water hose. By allowing to wash, there is an effect of improving the function of the washing machine and minimizing damage to the laundry.
