Description
본 고안은 김치냉장고용 냉매분배장치에 관한 것으로, 더욱 상세하게는 김치냉장고의 냉동사이클을 흐르는 냉매를 하나의 유입관으로 유입한 후, 각각 상시닫힘형 솔레노이드밸브에 의해 개폐되는 2개이상의 유출관을 통해 선택적으로 배출함으로써 냉매의 선택적 분배가 가능한 김치냉장고용 냉매분배장치에 관한 것이다.The present invention relates to a refrigerant distribution device for kimchi refrigerator, more specifically, two or more outlet pipes which are opened and closed by a normally closed solenoid valve after the refrigerant flowing through the freezing cycle of the kimchi refrigerator into one inlet pipe, respectively. It relates to a kimchi refrigerator refrigerant distribution device capable of selectively distributing the refrigerant by selectively discharge through.
일반적으로, 김치냉장고는 김치를 담아 저장하여 맛과 신선도를 장기간 유지시킬 수 있는 장치로서, 김치가 저장되는 2개 이상의 저장실을 냉동사이클을 순환하는 냉매를 이용하여 저온상태로 유지시키게 된다.이때, 김치냉장고에 설치되는 2개 이상의 저장실은 서로 분리된 공간을 이루고 있고, 냉동사이클을 순환하는 냉매는 하나의 유입관에서 각 저장실에 설치된 유출관으로 분기되어 순환하면서 각 저장실을 저온상태로 유지시키게 된다.여기서, 종래에는 도1에 도시된 바와 같이 냉동사이클을 순환하는 냉매가 하나의 냉매유입관으로 유입된 후, 연결분배관(20)에서 분기되어 각 냉매유출관(10,11)으로 유출되는데, 이때 각 저장실로 냉매를 공급하는 냉매유출관(10,11)에는 그 입구측에 각각 밸브몸체(21,22)가 설치되고, 각 밸브몸체는 그 냉매유로가 솔레노이드밸브(40)에 의해 개폐되어 냉매유출관으로 유출되는 냉매의 흐름을 단속하도록 구성되어 있다.그러나, 이러한 구조는 연결분배관(20), 밸브몸체(21,22) 등 그 부품수가 많아지면서 공간을 많이 차지하게 되고, 각 연결부위를 용접하여 연결함으로써 용접에 따른 제조공정수가 늘어날 뿐만 아니라 각 용접부위에서의 냉매유출가능성이 높아지는 문제가 초래된다.In general, the kimchi refrigerator is a device that can store the kimchi to maintain the taste and freshness for a long time, the two or more storage rooms where kimchi is stored is kept at a low temperature state using a refrigerant circulating a refrigeration cycle. The two or more storage compartments installed in the Kimchi refrigerator form a separate space from each other, and the refrigerant circulating in the refrigeration cycle is branched from one inlet pipe to the outlet pipe installed in each storage compartment to keep each storage compartment at a low temperature. Here, conventionally, as shown in FIG. 1, the refrigerant circulating in the refrigeration cycle flows into one refrigerant inlet pipe, and then branches from the connection distribution pipe 20 to be discharged into each refrigerant outlet pipe 10 and 11. In this case, the valve bodies 21 and 22 are respectively installed at the inlet side of the refrigerant outlet pipes 10 and 11 for supplying the refrigerant to the respective storage chambers. It is configured to control the flow of the refrigerant that is opened and closed by the solenoid valve 40 and flows out into the refrigerant outlet pipe. However, such a structure has a large number of parts such as the connection distribution pipe 20 and the valve bodies 21 and 22. While occupying a lot of space, by connecting each connecting portion by welding, not only does the number of manufacturing processes increase due to welding, but also causes a problem that the possibility of refrigerant leakage from each welding portion is increased.
본 고안은 밸브몸체에 있어 냉매유입관과 연결된 유입포트를 통해 유입되는 냉매가 유입로에서 분기되어 각각 상시닫힘형 솔레노이드밸브에 의해 개폐되는 밸브시트를 통해 다수의 유출로로 선택적으로 배출되도록 이루어져 그 냉매분배구조가 단순하면서 콤팩트하고, 그 용접부위수를 최소화하는 김치냉장고용 냉매분배장치를 제공함에 그 목적이 있다.The present invention is configured to selectively discharge the refrigerant flowing through the inlet port connected to the refrigerant inlet pipe in the valve body through the valve seat is opened and closed by the normally closed solenoid valve, respectively. It is an object of the present invention to provide a refrigerant distribution device for a kimchi refrigerator that has a simple and compact refrigerant distribution structure and minimizes the number of welded portions thereof.

At this time, the normally closed solenoid valve 40, which is controlled by a microcomputer that senses the room temperature of each storage compartment of the Kimchi refrigerator, operates when the coil 30 is energized. The iron core 31 is advanced to the fixed iron core 36 side by the induced electromagnetic force, so that the poppet 33 of the spool 34 selectively closes the valve seats 2 and 3, or the energization of the coil is interrupted. The poppet 33 is configured to selectively open the first and second valve seats while being retracted by the compression spring 38. Then, the solenoid valve 40 is provided inside the valve coupling holes 8 and 9. The refrigerant chambers 15 and 16 formed by the space are connected to the inflow path 14 and the outflow paths 4 and 5. On the other hand, the kimchi refrigerator refrigerant distribution device according to the present invention according to another embodiment, the refrigerant supplied to the inlet port 13 in the valve body 1 inlet path 14 The kimchi refrigerator refrigerant distribution device according to the present invention is provided to the inlet port 13 in the valve body (1) according to another embodiment The refrigerant may be configured to branch in three or more radial directions from the inflow path 14.
