본 발명은 냉/온자동판매기에 관한 것으로, 특히 2개의 증발기중 한 개의 증발기를 사용할 때에도 냉각능력을 최대한 발휘할 수 있도록 하여 효율을 극대화 시킬 수 있도록 된 냉/온자동판매기용 냉각장치에 관한 것이다.The present invention relates to a cold / hot vending machine, and more particularly to a cooling device for a cold / hot vending machine to maximize the efficiency by using the one of the two evaporators to maximize the cooling capacity.

일반적인 냉/온자동판매기는 도 1에 도시된 것과 같이, 외관을 형성함과 더불어 조절다리(11)로 평형을 유지하도록 설치된 외부케이스(10)와, 이 외부케이스(10)에 고정되는 수평격리판(12)를 매개로 하부에 설치된 기계실(20)과, 이 기계실(20)의 상부에는 수직격리판(13)을 매개로 좌.우측에는 냉장실(31)과 냉온장실(32)이 설치되어 있다.The general cold / hot vending machine, as shown in Figure 1, the outer case 10 and the horizontal isolation that is fixed to the outer case 10 installed to form an equilibrium with the control leg (11) to form the appearance The machine room 20 installed at the lower part through the plate 12 and the upper and lower sides of the machine room 20 are provided with a refrigerating chamber 31 and a cold room chamber 32 at the left and right sides. have.

여기서 상기 기계실(20)과 냉장실(31) 및 냉온장실(32)에는, 다수의 냉매관을 매개로 냉각싸이클을 이루도록 냉각장치(40)가 설치되어 있다.Here, in the machine room 20, the refrigerating chamber 31, and the refrigerating chamber 32, a cooling device 40 is provided so as to form a cooling cycle through a plurality of refrigerant pipes.

상기 냉각장치는 도 2에 도시된 것과 같이, 전원을 공급받아 냉매를 고온고압으로 압축하여 토출하는 압축기(41)와, 이 압축기(41)에 의해 압축된 고온고압의 냉매를 받아 고압상온의 액냉매로 응축시킬 수 있도록 배설된 응축기(42)와, 이 응축기(42)에서 응축된 냉매를 모세관(a,b)을 매개로 분기공급하여 갑압시킬 수 있도록 배설된 제1,2팽창밸브(43,44)와, 이 제1,2팽창밸브(43,44)를 통과하면서 감압된 냉매를 받아 주위의 열을 흡수하여 저온저압의 냉매로 기화시킴에 따라 주위공기를 차게 냉각시키는 제1,2증발기(45,46)로 이루어져 있다.As shown in FIG. 2, the cooling device receives a compressor 41 which is supplied with power and compresses and discharges the refrigerant at high temperature and high pressure, and receives the refrigerant of the high temperature and high pressure compressed by the compressor 41 to obtain a liquid at high pressure and room temperature. A condenser 42 disposed to condense with the refrigerant, and first and second expansion valves 43 arranged to branch and supply the refrigerant condensed in the condenser 42 through the capillary tubes a and b as a medium. 44 and the first and second coolers that cool the surrounding air as they receive the reduced pressure as they pass through the first and second expansion valves 43 and 44 to absorb ambient heat and vaporize them into a refrigerant having a low temperature and low pressure. It consists of evaporators 45 and 46.

여기서 냉/온자동판매기의 냉각장치에서 냉장실(31)과 냉온장실(32)를 모두 냉장실로 사용할 때의 냉매제어방법을 설명하면, 상기 응축기(42)에서 응축된 냉매는 제어부(도시않됨)에서 개폐되도록 제어하는 제1,2팽창밸브(43,44)를 통해 제1,2증발기(45,46)로 공급됨으로써 냉장실(31)과 냉온장실(32)이 모두 냉장실로 사용할 수 있게 된다.Here, the refrigerant control method when using both the refrigerating chamber 31 and the refrigerating chamber 32 as a refrigerating chamber in the cooling device of the cold / hot vending machine, the refrigerant condensed in the condenser 42 is controlled by a controller (not shown) By supplying the first and second evaporators 45 and 46 through the first and second expansion valves 43 and 44 to control the opening and closing, both the refrigerating chamber 31 and the refrigerating chamber 32 can be used as a refrigerating chamber.

그리고 냉/온자동판매기의 냉각싸이클에서 냉장실(31)과 냉온장실(32)를 냉장실과 온장실로 사용할 때의 냉매제어방법을 설명하면, 상기 응축기(42)에서 응축된 냉매는 제어부(도시않됨)에 의해 제2팽창밸브(44)는 폐쇄하고 제1팽창밸브(43)만을 통해 제1증발기(45)로만 공급되게 되어 냉장실은 일정온도 이하가 되게 되고, 상기 냉온장실(32)은 히터(도시않됨)의 가열에 의해 일정온도이상 으로 설정되어 온장실의 기능을 수행하게 된다.In addition, a refrigerant control method for using the refrigerating compartment 31 and the refrigerating compartment 32 as the refrigerating compartment and the warming compartment in the cooling cycle of the cold / hot vending machine will be described. The refrigerant condensed in the condenser 42 is controlled (not shown). As a result, the second expansion valve 44 is closed and supplied only to the first evaporator 45 through the first expansion valve 43 so that the refrigerating chamber is below a predetermined temperature, and the refrigerating chamber 32 is a heater (not shown). It is set above a certain temperature by heating, and performs the function of a warm room.

그러나 이러한 냉각장치는, 상기 냉온장실(32)을 온장실로 사용할 경우에 상기 제1팽창밸브(43)로부터 제1증발기(45)까지의 모세관(a)에 걸리는 압력강하는 더욱더 낮아져 제1증발기(45)에 들어가는 냉매순환량이 변화가 생긴다.However, such a cooling device has a lower pressure drop applied to the capillary tube (a) from the first expansion valve (43) to the first evaporator (45) when the cold / warm chamber (32) is used as a warm room. The amount of refrigerant circulating in 45 changes.

이로 인하여 제1증발기(45)쪽에 불균형적인 증발능력이 발생하여 냉장실(31)내의 상품을 냉각하기 위해 설정된 일정온도 이하로 떨어지기 전에 제어부에서 압축기(41)의 정지신호가 걸리게 되어 냉각하는 능력이 저하되는 문제점이 있었다.As a result, an unbalanced evaporation capacity is generated on the first evaporator 45 side, and a stop signal of the compressor 41 is caught by the control unit before the temperature falls below a predetermined temperature set to cool the goods in the refrigerating chamber 31. There was a problem of deterioration.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 응축기와 제1증발기의 사이에 설치된 감압비가 적은 모세관에 선택적으로 절환되는 냉온절환스위치에 의해 개폐되는 제3팽창밸브를 설치함으로써, 냉장실과 온장실로 사용할 경우에 냉장실의 증발기가 적정한 증발능력을 발휘할 수 있도록 한 냉/온자동판매기용 냉각장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by installing a third expansion valve that is opened and closed by a cold and hot water switch is selectively switched to a capillary tube with a low pressure reduction ratio installed between the condenser and the first evaporator, It is an object of the present invention to provide a cooling device for a cold / hot vending machine that enables the evaporator of the refrigerating compartment to exhibit an appropriate evaporation capacity when used as a overheating compartment.
