Description

냉장/온장 겸용 쇼케이스{COOLING/HEATING SHOWCASE}Refrigerated / cold showcase {COOLING / HEATING SHOWCASE}

본 발명은 쇼케이스에 관한 것으로, 특히 냉장과 온장을 선택하여 사용할 수 있는 냉장/온장 겸용 쇼케이스에 관한 것이다.TECHNICAL FIELD The present invention relates to a showcase, and more particularly, to a refrigeration / cold combination showcase which can be used by selecting refrigeration and heating.

일반적으로 쇼케이스는 슈퍼마켓에서 판매하는 육류나 채소류 및 음료류의 신선도를 유지하면서 이들 상품을 전시하기 위하여 사용하고 있다.Showcases are generally used to display these products while maintaining the freshness of meats, vegetables and beverages sold in supermarkets.

쇼케이스는 냉동사이클을 이용하여 냉기를 공급하고 이 냉기로 상품을 냉장 보관함으로써 신선도를 유지하는 것이다.The showcase is to maintain freshness by supplying chilled air using refrigeration cycles and refrigerated goods with this chiller.

도 1은 종래 냉장용 쇼케이스의 일례를 보인 개략도이다.1 is a schematic view showing an example of a conventional refrigeration showcase.

이에 도시한 바와 같이 쇼케이스는 내부에 냉기공급장치(20)를 설치하기 위한 기계실(11)과 상품을 진열하기 위한 진열실(12)을 형성하는 본체(10)와, 본체(10)의 진열실(12)을 개폐하기 위한 도어(D)로 구성하고 있다.As shown in the drawing, the showcase includes a machine room 11 for installing a cold air supply device 20 therein, a main body 10 forming a display room 12 for displaying goods, and a display room 12 of the main body 10. ) Is configured as a door (D) for opening and closing.

본체(10)는 진열실(12)의 하측에 상기한 기계실(11)을 형성하고 진열실(12)의 상측에는 그 진열실(12)을 통과하면서 더워진 냉기를 냉각시키는 냉각실(13)을 형성하며 진열실(12)의 배면에는 냉각실(13)에 연통하여 찬 냉기를 진열실(12)로 공급하는 냉기유로(14)를 형성하고 있다.The main body 10 forms the machine room 11 described above on the lower side of the display chamber 12, and forms a cooling chamber 13 on the upper side of the display chamber 12 to cool the hot air while passing through the display chamber 12. A cold air flow passage 14 is formed on the rear surface of the display chamber 12 so as to communicate with the cooling chamber 13 and supply cold cold air to the display chamber 12.

냉기공급장치(20)는 기계실(11)에 설치하는 압축기(21)와 응축기(22), 그리고 응축기(22)에 연결하는 상기한 냉각실(13)에 설치하는 증발기(23)로 이루어져 있다. 증발기(23)의 출구는 압축기(21)의 출구에 연결하여 상기한 압축기(21)와 응축기(22) 그리고 증발기(23)가 단일 유로의 폐루프를 형성하고 있다.The cold air supply device 20 includes a compressor 21 installed in the machine room 11, a condenser 22, and an evaporator 23 installed in the cooling chamber 13 connected to the condenser 22. The outlet of the evaporator 23 is connected to the outlet of the compressor 21 so that the compressor 21, the condenser 22, and the evaporator 23 form a closed loop of a single flow path.

또, 증발기(23)의 일측에는 진열실(12)의 더운 공기를 흡입하여 냉기유로(14)로 순환시키는 송풍팬(30)을 설치하고 있다.In addition, a blower fan 30 is provided on one side of the evaporator 23 to suck hot air from the display chamber 12 and circulate the cold air flow path 14.

도면중 미설명 부호인 14a는 냉기흡입구멍이다.Reference numeral 14a in the figure denotes a cold air suction hole.

상기와 같은 쇼케이스는 다음과 같이 동작한다.The showcase as above operates as follows.

즉, 기계실(11)에 설치한 압축기(21)에 의해 압축되어진 냉매는 고온 고압의 기체와 액체의 혼합상태가 되고, 그 냉매는 다시 기계실(11)에 설치한 응측기(22)로 이송되어 고온 고압의 액체상태가 되며, 고온 고압의 액체 냉매는 팽창밸브(도 2에 도시)(24)를 통하여 기화함과 동시에 냉각실(13)에 장착한 증발기(23)로 이송되어 증발기(23)의 내부에서 냉매가 기화되면서 소모되는 기화열로 주위의 온도를 낮추는 냉기가 발생된다.That is, the refrigerant compressed by the compressor 21 installed in the machine room 11 is in a mixed state of a gas and a liquid of high temperature and high pressure, and the refrigerant is again transferred to the measuring device 22 installed in the machine room 11. It becomes a liquid state of high temperature and high pressure, and the liquid refrigerant of high temperature and high pressure vaporizes through an expansion valve (shown in FIG. 2) 24 and is transferred to an evaporator 23 mounted in the cooling chamber 13 to be evaporator 23. As the refrigerant is evaporated inside the heat of vaporization is consumed to reduce the temperature of the surrounding air is generated.

이 냉기는 냉기유로(14)를 통해 유입되었다가 냉기흡입구멍(14a)을 통해 진열실(12)로 흡입되어 그 진열실(12)에 진열되어 있는 각종 식품이나 음료를 적정온도로 냉장 보관하게 되는 것이었다.The cold air was introduced through the cold air flow passage 14 and sucked into the display chamber 12 through the cold air suction hole 14a to store various foods or beverages displayed in the display chamber 12 at an appropriate temperature. .

그러나, 상기와 같은 종래 냉장용 쇼케이스에 있어서는, 냉기공급장치(20)가 단일 폐루프를 이루도록 구성됨에 따라 항상 차가운 냉기만을 공급하게 되어 냉장부하가 큰 하절기에는 유용한 반면, 냉장부하가 크지 않은 동절기에는 고가의 제품임에도 불구하고 거의 사용하지 않거나 단순 수납공간으로만 사용하여 제품의 활용도가 낮은 단점이 있었다.However, in the conventional refrigeration showcase as described above, since the cold air supply device 20 is configured to form a single closed loop, only cold cold air is always supplied, so it is useful in the winter season when the refrigeration load is large, but in the winter period when the refrigeration load is not large. Although it is an expensive product, there is a disadvantage in that the utilization of the product is low because it is rarely used or used only as a simple storage space.

본 발명은 상기와 같은 종래 냉장용 쇼케이스가 가지는 문제점을 감안하여 안출한 것으로, 냉장부하에 따라 냉기공급장치의 운전상태를 가변함으로써 제품의 활용도를 높일 수 있는 냉장/온장 겸용 쇼케이스를 제공하려는데 본 발명의 목적이 있다.The present invention has been made in view of the problems of the conventional refrigeration showcase as described above, to provide a refrigeration / cold storage showcase that can increase the utilization of the product by varying the operating state of the cold air supply device according to the refrigeration load. There is a purpose.
