본 발명은 밸브 본체 내에 복수의 스태핑모터를 구비하고 각 스태핑모터를 제어부를 통해 선택적으로 개폐가능하게 구성함으로써 냉매의 복수유로 제어가 가능한 밸브에 관한 것이다.The present invention relates to a valve having a plurality of stepping motors in the valve body and configured to selectively open and close each stepping motor through a control unit to control a plurality of channels of refrigerant.

일반적으로, 냉장고, 공기조화기, 김치냉장고 등은 냉동장치이다. 이러한 냉동장치들은 장치 내 구비된 냉동사이클을 순환하는 고온 고압의 냉매에 의하여 장 치 내의 온도를 조절한다. Generally, a refrigerator, an air conditioner, a kimchi refrigerator, or the like is a freezing device. These refrigeration units control the temperature in the device by the high temperature and high pressure refrigerant circulating the refrigeration cycle provided in the device.

이와 같은 냉동장치로서 가장 일반적인 냉장고는 각 식품보관칸과 연계된 2방향(2WAY) 솔레노이드밸브의 개폐제어에 의해서 냉동사이클을 구성하고 있다. 이때 이용되는 2방향 스태핑모터 밸브를 도 1에 도시하고 있다. The refrigerator most common as such a refrigeration device comprises a refrigeration cycle by opening and closing control of a 2-way solenoid valve associated with each food storage compartment. The two-way stepping motor valve used at this time is shown in FIG.

도 1에서 보는 바와 같이 스태핑모터 밸브는, 중심부에 상하로 이동 가능한 플렌져(37)를 설치하고, 상기 플렌져(37)의 상하 이동을 제어하기 위한 코일(31)을 상기 플렌져(37)의 주변에 설치하고 있다. 상기 플렌져(37)의 하부에는 실링볼(33)이 부착되고 있으며, 상기 실링볼(33)은 상기 솔레노이드밸브에 구성된 2개의 밸브인 입력포트(39)와 출력포트(41)를 개폐하는 구성을 하고 있다. 상기 입력포트(39)와 출력포트(41)는 서로 연통되어 있고, 상기 플렌져(37)의 하부에 부착된 실링볼(33)에 의해서 두 포트의 연통이 개폐된다. 그리고 상기 플렌져(37)는 내부에 구비된 스프링(35)에 의해서 하부방향으로 이동되는 힘을 받고 있다.As shown in FIG. 1, the stepping motor valve includes a flanger 37 that is movable up and down in the center, and a coil 31 for controlling the vertical movement of the flanger 37. We install in the outskirts of. A sealing ball 33 is attached to the lower portion of the flanger 37, and the sealing ball 33 is configured to open and close the input port 39 and the output port 41, which are two valves of the solenoid valve. Doing The input port 39 and the output port 41 communicate with each other, and communication between the two ports is opened and closed by a sealing ball 33 attached to the lower portion of the flanger 37. The flanger 37 receives a force moved downward by a spring 35 provided therein.

따라서 상기 코일(31)에 전원을 공급하면, 전자석의 원리에 의하여 상기 플렌져(37)가 상부로 이동된다. 이때 입력포트(39)와 출력포트(41)의 연통을 차단하고 있던 실링볼(33)도 상기 플렌져(37)와 같이 이동되면서 상기 입력포트(39)와 출력포트(41)는 서로 연통된다. 그러나 상기 코일(31)에 공급되던 전원이 차단되면, 상기 스프링(35) 력에 의해서 상기 플렌져(37)는 하부로 이동된다. 상기 플렌져(37)가 하부로 이동되면, 상기 플렌져(37)의 하단에 설치된 실링볼(33)이 상기 입력포트(39)와 출력포트(41)의 연통을 차단시킨다. Therefore, when power is supplied to the coil 31, the flanger 37 is moved upward by the principle of the electromagnet. At this time, the sealing ball 33, which blocks the communication between the input port 39 and the output port 41, is also moved together with the flanger 37 while the input port 39 and the output port 41 communicate with each other. . However, when the power supplied to the coil 31 is cut off, the flanger 37 is moved downward by the spring 35 force. When the flanger 37 moves downward, the sealing ball 33 installed at the lower end of the flanger 37 blocks the communication between the input port 39 and the output port 41.

그러나 상기와 같이 종래 냉동사이클에 이용하고 있는 스태핑모터 밸브는 내 부에 스태핑모터가 1개가 구비되어 단방향 2WAY제어만이 가능했었던 한계가 있었다.However, as described above, the stepping motor valve used in the conventional refrigeration cycle has a limitation that only one-way 2WAY control is possible because one stepping motor is provided inside.

이에 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 밸브 본체 내에 복수의 스태핑모터를 구비하고 각 스태핑모터를 제어부를 통해 선택적으로 개폐가능하게 구성함으로써 냉매의 복수유로 제어가 가능한 밸브를 제공함에 있다.Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a plurality of stepping motor in the valve body and to control the plurality of flow path of the refrigerant by selectively opening and closing each stepping motor through the control unit In providing a possible valve.

전술한 목적을 달성하기 위한 본 발명의 밸브는, 냉매 유입구 및 유출구가 형성되고, 내부에 상기 냉매 유입구에서 유출구로 이어지는 유로를 개폐할 수 있도록 제어부를 통해 제어되는 스태핑모터가 설치된 밸브에 있어서, 상기 유출구 및 상기 스태핑모터는 복수 개로 구비되며, 상기 각 스태핑모터는 상기 제어부에 의해 상기 각각의 유출구를 선택적으로 개폐하도록 형성한 것을 특징으로 한다.In the valve of the present invention for achieving the above object, in the valve is provided with a stepping motor is formed through the control unit to open and close the flow path leading to the outlet from the refrigerant inlet and outlet is formed therein, Outlet and the stepping motor is provided in plurality, each stepping motor is characterized in that formed by the control unit to selectively open and close the respective outlet.

상기한 구성에 의하면, 밸브 본체 내에 2개의 스태핑모터를 구비하고 상기 각 스태핑모터를 제어부를 통해 선택적으로 개폐가능하도록 구성함으로써, 냉매의 3방향(3WAY) 제어가 가능해지는 효과를 얻을 수 있다.According to the above configuration, by providing two stepping motors in the valve body and configured to selectively open and close each of the stepping motors through the control unit, it is possible to obtain the effect that the three-way (3WAY) control of the refrigerant is possible.

상기 제1,2스태핑모터(100a)(100b)는 외주부에 코일(150)이 감겨진 케이스(110)가 구비되고, 상기 케이스(110) 내부에는 로터(130)가 회전가능하게 설치되며, 상기 로터(130)의 하단부에는 제1,2냉매 유출구(104)(105)를 개폐하는 실링부(140)가 형성되고, 상기 로터(130)의 상단에는 상기 로터(130)를 하방으로 밀어주도록 탄성력을 인가하게 되는 스프링(120)이 지지된 구조를 이룬다.The first and second stepping motors 100a and 100b include a case 110 in which a coil 150 is wound around an outer circumference thereof, and a rotor 130 is rotatably installed in the case 110. The lower end of the rotor 130 is formed with a sealing portion 140 for opening and closing the first and second refrigerant outlets 104, 105, the elastic force to push the rotor 130 downward on the upper end of the rotor 130 The spring 120 is applied to form a supported structure.

상기 제1,2냉매 유출구(104)(105)는 냉매가 유출되는 초기지점에 하방으로 갈수록 점차 직경이 감소되도록 테이퍼진 경사부가 형성되고, 상기 경사부의 하단에서 다시 내측방향을 향하여 수평으로 인입된 수평부가 형성되며, 상기 수평부의 내측단으로부터 수직하게 하방으로 연결된 수직부가 형성된 구조를 갖는다.The first and second refrigerant outlets 104 and 105 have a tapered inclined portion formed to gradually decrease in diameter downward toward an initial point at which the refrigerant flows out, and is horizontally drawn toward the inner side again from the lower end of the inclined portion. A horizontal portion is formed, and has a structure in which a vertical portion connected vertically downward from an inner end of the horizontal portion is formed.
