본 발명은 김치저장고의 냉매 흐름 제어장치에 관한 것으로서, 좀더 구체적으로는 2개의 저장실을 갖는 김치저장고에서 응축기로부터 응축되어 증발기 측으로 이동하는 냉매의 흐름을 선택적으로 제어할 수 있도록 하는 김치저장고의 냉매 흐름 제어장치에 관한 것이다.The present invention relates to a refrigerant flow control apparatus of a kimchi reservoir, and more particularly, a refrigerant flow of a kimchi reservoir to selectively control the flow of a refrigerant condensed from a condenser and moving to an evaporator in a kimchi reservoir having two storage compartments. It relates to a control device.

일반적으로 김치저장고는 기존의 일반적인 냉장고와는 달리, 김치와 같은 발효 음식물을 적절하게 숙성시켜 음식물의 맛을 보다 더 향상시킬 수 있도록 하는 주방용 전자제품으로서, 이러한 김치저장고는 냉각 방식에 따라 간냉식 또는 직냉식으로 대별된다.In general, unlike the conventional refrigerators, kimchi storage is a kitchen electronic product that allows the fermented foods such as kimchi to be appropriately aged to improve the taste of the food. It is roughly divided into.

도 1은 일반적인 김치저장고의 냉각사이클을 나타낸 구성도로서, 저장실이 일정온도 이하로 유지되도록 하는 냉각사이클은 저온 저압의 기체냉매를 압축하여 고온 고압의 기체냉매로 변화시키는 압축기(1)와, 상기 압축기(1)에 의해 변환된 고온 고압의 기체냉매를 고온 고압의 액체냉매로 응축하는 응축기(2)와, 상기 응축기(2)를 지난 액체냉매의 흐름을 제어하는 삼방밸브(3)와, 상기 삼방밸브(3)에 연결되어 응축기(2)를 지난 고온 고압의 액체냉매를 공급받아 고온 저압의 액체냉매로 변환하는 캐필러리 튜브(4)와, 상기 캐필러리 튜브(4)를 지난 고온 저압의 액체냉매는 증발기(5)를 지나면서 저온, 저압의 기체냉매로 변화되면서 증발하여 주변의 공기를 냉각시키므로 냉기가 발생된다.1 is a configuration diagram showing a cooling cycle of a general kimchi storage, the cooling cycle for maintaining the storage chamber below a certain temperature is a compressor (1) for compressing the low-temperature low-pressure gas refrigerant to a high-temperature high-pressure gas refrigerant, and A condenser (2) for condensing the high temperature and high pressure gas refrigerant converted by the compressor (1) into a high temperature and high pressure liquid refrigerant, a three-way valve (3) for controlling the flow of the liquid refrigerant passing through the condenser (2), and Capillary tube (4) connected to the three-way valve (3) is supplied to the high temperature and high pressure liquid refrigerant passing the condenser (2) to a high temperature low pressure liquid refrigerant, and the high temperature past the capillary tube (4) The low pressure liquid refrigerant evaporates while changing into a low temperature, low pressure gas refrigerant passing through the evaporator 5, thereby cooling the surrounding air, thereby generating cold air.

이러한 냉각사이클은 압축기(1), 응축기(2), 삼방밸브(3), 캐필러리 튜브(4), 증발기(5)를 연결하는 냉매관(6)을 통해 냉매가 순환되므로 동작이 이루어지게 된다.The cooling cycle is circulated through the refrigerant pipe (6) connecting the compressor (1), condenser (2), three-way valve (3), capillary tube (4), evaporator (5) so that the operation is made. do.

도 2는 종래의 김치저장고를 나타낸 종단면도로서, 본체(7)의 상측 내부에 2개의 저장실(8a)(8b)이 각각 독립되게 구비되어 있고, 상기 저장실(8a)(8b)의 상부 에는 도어(9)가 힌지(도시는 생략함)를 중심으로 개폐 가능하게 설치되어 있다.FIG. 2 is a vertical cross-sectional view showing a conventional kimchi storage, in which two storage chambers 8a and 8b are independently provided inside the main body 7, and a door is provided above the storage chambers 8a and 8b. (9) is provided so that opening and closing is possible centering on hinge (illustration omitted).

상기 저장실(8a)(8b)의 둘레에는 저장실의 온도를 저온 상태로 유지시키기 위해 저온, 저압의 기체냉매로 변환되면서 증발하여 주변의 공기를 냉각시키는 증발기(10a)(10b)가 각각 설치되어 있는데, 상기 응축기(2)를 통과한 냉매가 흐르는 냉매관(6) 상에는 냉매의 흐름을 제어하는 밸브(11)가 설치되어 있다.Evaporators 10a and 10b are installed around the storage chambers 8a and 8b to convert the refrigerant into low-temperature and low-pressure gas refrigerants to keep the temperature of the storage chamber at a low temperature. On the refrigerant pipe 6 through which the refrigerant having passed through the condenser 2 flows, a valve 11 for controlling the flow of the refrigerant is provided.

도 3a 및 도 3b는 종래의 김치저장고용 냉매 흐름 제어장치(실용신안등록 제241242호)의 구성을 나타낸 종단면도로서, 응축기(2)에서 응축된 냉매가 유입관(12)을 통해 하우징(13)의 내부로 유입됨에 따라 하우징(13)의 내부에 설치되어 동시 또는 선택적으로 동작하는 2개의 솔레노이드 밸브(14)(15)에 의해 밸브체(14a)(14b)가 유로(16a)(16b)를 개방하는 구조로 되어 있어 유로가 개방되면 냉매가 유출관(17a)(17b)을 통해 저장실(8a)(8b)의 둘레에 설치된 증발기(10a)(10b)측으로 공급된다.3A and 3B are longitudinal cross-sectional views showing the structure of a conventional Kimchi reservoir refrigerant flow control device (Utility Model Registration No. 241242), in which the refrigerant condensed in the condenser 2 passes through the inlet pipe 12 and the housing 13. The valve body (14a) (14b) is the flow path (16a) (16b) by two solenoid valves (14) (15) installed in the housing (13) and operating simultaneously or selectively as they flow into the interior of the housing (13). When the flow path is opened, the refrigerant is supplied to the evaporators 10a and 10b provided around the storage chambers 8a and 8b through the outlet pipes 17a and 17b.

따라서, 유입포트에 고정된 유입관(12)을 통해 냉매가 하우징(13)의 내부로 유입되면 유입된 냉매는 밸브체(14a)(14b)의 개폐 여부에 따라 유로(16a)(16b)가 닫히거나, 열리게 되므로 유출관(17a)(17b)을 통해 각 저장실(8a)(8b)의 둘레에 설치된 증발기(10a)(10b) 측으로 이동하여 저장실을 저온상태로 유지시키게 된다.Therefore, when the refrigerant flows into the housing 13 through the inflow pipe 12 fixed to the inflow port, the flow of refrigerant flows in accordance with whether the valve bodies 14a and 14b are opened or closed. Since it is closed or opened, it moves to the evaporator 10a, 10b provided around each storage chamber 8a, 8b through the outflow pipe 17a, 17b, and keeps a storage chamber at low temperature.

예를 들어, 2개의 밸브체(14a)(14b)가 동시에 후퇴하여 유로(16a)(16b)를 개방한 경우에는 각 저장실(8a)(8b)의 둘레에 설치된 증발기(10a)(10b) 측으로 냉매가 동시에 공급되어 각 저장실을 저온상태로 유지하고, 어느 하나의 저장실(8a)이 설정된 온도를 유지하여 저장실의 둘레에 설치된 증발기(10a) 측으로 냉매의 공급 을 중단시키기 위해 밸브체(14a)가 전진하여 유로(16a)를 폐쇄하면 다른 일 측의 증발기(8b)로만 냉매가 공급되므로 압축기의 구동시간을 줄이게 된다.For example, when the two valve bodies 14a and 14b retreat at the same time to open the flow paths 16a and 16b, they are directed toward the evaporators 10a and 10b provided around the respective storage chambers 8a and 8b. Refrigerant is supplied at the same time to keep each storage chamber at a low temperature state, any one of the storage chamber (8a) to maintain the set temperature to stop the supply of the refrigerant to the evaporator (10a) side installed around the storage chamber is provided with a valve body (14a) When the flow path 16a is closed by advancing, the refrigerant is supplied only to the evaporator 8b on the other side, thereby reducing the driving time of the compressor.

그러나, 이러한 구조를 갖는 종래의 장치는 냉매가 순환하는 냉매관의 유로 상에 고가인 2개의 솔레노이드밸브 또는 스탭 밸브를 설치하여 유출관과 통하는 유로를 개폐하도록 구성되어 있어 김치저장고의 생산원가가 상승되는 결과를 초래하였음은 물론 각 저장실의 온도 변화에 따라 2개의 솔레노이드밸브를 각각 제어하여야하므로 회로의 구성이 복잡해지게 되는 문제점이 발생되었다. However, the conventional apparatus having such a structure is configured to open and close the flow path communicating with the outlet pipe by installing two expensive solenoid valves or step valves on the flow path of the refrigerant pipe through which the refrigerant circulates, thereby increasing the production cost of the kimchi storage. In addition, the two solenoid valves must be controlled individually according to the temperature change of each storage compartment, resulting in a complicated circuit configuration.

본 발명은 이와 같은 종래의 문제점을 해결하기 위해 안출한 것으로서, 그 구조를 개선하여 1개의 솔레노이드밸브와 비교적 가격이 저렴한 2개의 체크밸브를 사용하여 각 저장실의 온도 변화에 따라 냉매의 흐름을 제어할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve such a conventional problem, and by improving its structure, one solenoid valve and two relatively inexpensive check valves are used to control the flow of refrigerant according to the temperature change of each storage compartment. The purpose is to make it possible.

상기 목적을 달성하기 위한 본 발명의 형태에 따르면, 응축기에 연결된 냉매관을 분기하여 2개의 저장실의 둘레에 설치된 증발기 측으로 냉매가 공급되도록 하고 상기 냉매관 상에는 밸브를 설치하여 냉매의 흐름을 제어하도록 구성된 김치저장고의 냉매 흐름 제어장치에 있어서, 일 측의 증발기와 연결된 냉매관에 솔레노이드밸브를 설치하고 냉매관으로부터 분기된 분기관에는 제1체크밸브를 설치함과 동시에 솔레노이드밸브의 후단 및 제1체크밸브의 후단사이에는 제2체크밸브가 설치된 연장관을 연결하여서 된 김치저장고의 냉매 흐름 제어장치가 제공된다.According to an aspect of the present invention for achieving the above object, it is configured to branch the refrigerant pipe connected to the condenser so that the refrigerant is supplied to the evaporator side installed around the two storage chambers and to install a valve on the refrigerant pipe to control the flow of the refrigerant. In the refrigerant flow control device of the Kimchi storage, the solenoid valve is installed in the refrigerant pipe connected to the evaporator on one side, and the first check valve is installed in the branch pipe branched from the refrigerant pipe, and the rear end of the solenoid valve and the first check valve. Between the rear ends of the Kimchi reservoir is provided with a refrigerant flow control device connected to the extension pipe is installed.

이하, 본 발명을 일 실시예로 도시한 도 4를 참고하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, described in more detail with reference to Figure 4 showing the present invention as an embodiment.

도 4는 본 발명에 따른 냉각사이클을 보여주는 구성도이다.4 is a configuration diagram showing a cooling cycle according to the present invention.

도면에 도시된 바와 같이, 본 발명은 압축기(1)의 구동에 따라 압축된 고온, 고압의 기체 냉매를 고온, 고압의 액체 냉매로 상 변화시키는 응축기(2)가 냉매관(6a)으로 연결되어 있고, 상기 응축기(2)와 캐필러리 튜브(4a)사이에 연결된 냉매관(6b)에는 냉매의 흐름을 제어하는 솔레노이드밸브(21)가 설치되어 있어 일 측의 증발기(10a)로 공급되는 냉매의 흐름을 제어하도록 되어 있다.As shown in the figure, the present invention is connected to the refrigerant pipe (6a) is a condenser (2) for changing the high-temperature, high-pressure gas refrigerant to a high-temperature, high-pressure liquid refrigerant in accordance with the operation of the compressor (1) The solenoid valve 21 for controlling the flow of the refrigerant is installed in the refrigerant pipe 6b connected between the condenser 2 and the capillary tube 4a, and the refrigerant supplied to the evaporator 10a on one side thereof. To control the flow of

그리고, 상기 냉매관(6b)으로부터 분기된 분기관(6d)에는 냉매의 역류를 방지하는 제1체크밸브(22)가 설치되어 있고, 솔레노이드밸브(21)의 후단에 위치한 냉매관(6b)과 제1체크밸브(22)의 후단에 위치하는 분기관(6d)사이에는 제2체크밸브(23)가 설치된 연장관(6e)이 연결되어 있으며, 각 증발기(10a)(10b)와 압축기(1) 사이에는 회수관(6c)이 연결되어 있다.In addition, the branch pipe 6d branched from the refrigerant pipe 6b is provided with a first check valve 22 for preventing a backflow of the refrigerant, and a refrigerant pipe 6b located at the rear end of the solenoid valve 21. An extension pipe 6e provided with a second check valve 23 is connected between the branch pipes 6d positioned at the rear end of the first check valve 22. Each evaporator 10a, 10b and the compressor 1 are connected. The recovery pipe 6c is connected between them.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

먼저, 압축기(1)가 구동하면 압축기에서 압축된 냉매가 냉매관(6a) - 냉매관(6b) 및 분기관(6d) - 회수관(6c)을 따라 순환하면서 제1,2저장실(8a)(8b)을 저온의 상태로 유지시키게 된다.First, when the compressor 1 is driven, the refrigerant compressed by the compressor circulates along the refrigerant pipe 6a-the refrigerant pipe 6b and the branch pipe 6d-the recovery pipe 6c, and the first and second storage chambers 8a. (8b) is kept at a low temperature.

상기한 바와 같이 사이클을 이루면서 냉매가 순환할 때 제1,2저장실(8a)(8b)의 둘레에 설치된 증발기(10a)(10b)로 냉매를 동시에 공급하여 저온 저압의 기체냉매로 변화되는 과정에서 증발하여 주변의 공기를 냉각시키고자 할 경우에는 솔레노 이드밸브(21)에 전원을 인가하여 유로를 개방하므로써, 가능해지게 된다.As described above, when the refrigerant circulates in a cycle, the refrigerant is simultaneously supplied to the evaporators 10a and 10b installed around the first and second storage chambers 8a and 8b to change into a low temperature low pressure gas refrigerant. When the air is to be evaporated to cool the surrounding air, power is supplied to the solenoid valve 21 to open the flow path.

즉, 솔레노이드밸브(21)의 유로를 개방하면 응축기(2)를 통과하면서 고온, 고압의 액체로 상 변화한 냉매가 냉매관(6b) - 솔레노이드밸브(21) - 캐필러리 튜브(4a)를 거쳐 일 측에 위치된 증발기(10a)로 공급되므로 제1저장실(8a)을 저온 상태로 유지하게 된다.That is, when the flow path of the solenoid valve 21 is opened, the refrigerant, which has changed into a liquid of high temperature and high pressure while passing through the condenser 2, passes through the refrigerant tube 6b-solenoid valve 21-capillary tube 4a. Since it is supplied to the evaporator 10a located on one side, the first storage chamber 8a is maintained at a low temperature.

상기한 바와 같이 냉매관(6b)을 따라 이동하는 냉매 중 일부의 냉매는 분기관(6d)을 통해 다른 일 측의 증발기(10b)로 공급되므로 제2저장실(8b)을 동시에 저온 상태로 유지시킬 수 있게 된다.As described above, some of the refrigerant moving along the refrigerant pipe 6b are supplied to the evaporator 10b on the other side through the branch pipe 6d, thereby maintaining the second storage chamber 8b at a low temperature. It becomes possible.

이러한 상태에서 제1저장실(8a)의 둘레에 위치한 증발기(10a) 측으로 냉매의 흐름을 제어하고자 할 경우에는 솔레노이드밸브(21)에 인가하고 있던 전원을 차단시키면 된다.In such a state, in order to control the flow of the refrigerant toward the evaporator 10a located around the first storage chamber 8a, the power applied to the solenoid valve 21 may be cut off.

이에 따라, 냉매관(6b)을 통해 제1저장실(8a)의 둘레에 설치된 증발기(10a)로 냉매가 공급되지 않고, 분기관(6d) 및 캐필러리 튜브(4b)를 거쳐 제2저장실(8b)의 둘레에 설치된 증발기(10b) 측으로만 냉매가 공급되는데, 이 때 연장관(6e) 상에는 제2체크밸브(23)가 설치되어 있어 분기관(6d)을 따라 공급되던 냉매가 연장관(6e) 측으로 역류되지 않게 되는 것이다.Accordingly, the refrigerant is not supplied to the evaporator 10a provided around the first storage chamber 8a through the refrigerant tube 6b, and passes through the branch pipe 6d and the capillary tube 4b to the second storage chamber ( The refrigerant is supplied only to the evaporator 10b provided around the periphery of 8b. At this time, the second check valve 23 is provided on the extension pipe 6e, and the refrigerant supplied along the branch pipe 6d is extended to the extension pipe 6e. It will not flow back to the side.

이상에서 설명한 바와 같이 본 발명은 1개의 솔레노이드밸브와 비교적 가격이 저렴한 2개의 체크밸브를 이용하여 저장실의 둘레에 설치된 증발기 측으로 공급되는 냉매의 흐름을 제어하게 되므로 김치저장고의 생산원가를 절감하게 됨은 물론 솔레노이드밸브의 구동에 따른 제어부의 구성이 간단해 지는 효과를 얻게 된다.As described above, the present invention uses a single solenoid valve and two relatively inexpensive check valves to control the flow of the refrigerant supplied to the evaporator installed around the storage compartment, thereby reducing the production cost of the kimchi reservoir. The configuration of the control unit according to the operation of the solenoid valve is obtained to simplify the effect.
