図１５は本発明の第３の実施形態を示すもので、ショーケースの要部正面図である。尚、前記第１の実施形態と同等の構成部分には同一の符号を付して示す。   FIG. 15 shows a third embodiment of the present invention and is a front view of the main part of a showcase. In addition, the same code | symbol is attached | subjected and shown to the component equivalent to the said 1st Embodiment.

本実施形態の冷却ユニットの接続構造としては、図１６に示すように、冷却ユニット４の上面に設けた空気吸入口４ｇの内部に空気吐出口４ｈが位置するように設け、空気流出口２ｅ及び空気流入口２ｆをそれぞれ空気吸入口４ｇ及び空気吐出口４ｈと対向する位置に設けている。空気吸入口４ｇと空気流出口２ｅを還気ダクト１７によって接続するとともに、空気吐出口４ｈと空気流入口２ｆを給気ダクト１８によって接続することにより、還気ダクト１７の内側と給気ダクト１８の外側との間を商品収納部２から冷却ユニット４に向かって空気が流通し、給気ダクト１８の内側を冷却ユニット４から商品収納部２に向かって空気が流通するようになっている。また、空気吸入口４ｇの下方には、給気ダクト１８及び蒸発器４ｄの結露水、蒸発器４ｄの除霜運転によって融解した霜を受ける結露水受容部としてのドレン受け１９が設けられ、その最下部には結露水及び融解した霜を図示しない除霜水皿及び除霜水タンクに流通させるためのドレン孔１９ａが設けられている。   As shown in FIG. 16, the cooling unit connection structure of the present embodiment is provided so that the air discharge port 4 h is located inside the air suction port 4 g provided on the upper surface of the cooling unit 4. The air inlet 2f is provided at a position facing the air inlet 4g and the air outlet 4h, respectively. The air inlet 4g and the air outlet 2e are connected by the return air duct 17, and the air outlet 4h and the air inlet 2f are connected by the air supply duct 18, whereby the inside of the return air duct 17 and the air supply duct 18 are connected. Air flows from the product storage unit 2 toward the cooling unit 4 between the outside and the air supply duct 18, and air flows from the cooling unit 4 toward the product storage unit 2 inside the air supply duct 18. Also, below the air inlet 4g, there is provided a drain receiver 19 as a condensed water receiving portion that receives condensed water from the air supply duct 18 and the evaporator 4d and frost melted by the defrosting operation of the evaporator 4d. A drain hole 19a for allowing the dew condensation water and the melted frost to flow through a defrost water tray and a defrost water tank (not shown) is provided at the bottom.

以上のように構成された冷凍機器の冷却ユニット接続構造において、まず、前記第１の実施形態と同様に、冷却ユニット４をガイド部材３ｄに沿って機械室３内に収納して位置決めする。次に、給気ダクト１８及び還気ダクト１７をショーケース本体１の空気流入口２ｆ及び空気流出口２ｅに順次接続する。これにより、商品収納部２内の空気は還気ダクト１７の内側と給気ダクト１８の外側との間を流通して冷却ユニット４に吸入され、蒸発器４ｄによって冷却された空気は給気ダクト１８内を介して商品収納部２に流通する。このとき、給気ダクト１８の外側及び蒸発器４ｄが結露する場合には、結露水は還気ダクト１７及び蒸発器４ｄの下方に位置するドレン受け１９に落下してドレン孔１９ａを介して除霜水皿及び除霜水タンクに流通する。   In the cooling unit connection structure of the refrigeration equipment configured as described above, first, similarly to the first embodiment, the cooling unit 4 is housed and positioned in the machine chamber 3 along the guide member 3d. Next, the air supply duct 18 and the return air duct 17 are sequentially connected to the air inlet 2 f and the air outlet 2 e of the showcase body 1. Thereby, the air in the product storage unit 2 flows between the inside of the return air duct 17 and the outside of the air supply duct 18 and is sucked into the cooling unit 4, and the air cooled by the evaporator 4 d is supplied to the air supply duct. The product is distributed to the product storage unit 2 through 18. At this time, if the outside of the air supply duct 18 and the evaporator 4d are condensed, the condensed water falls on the drain receiver 19 located below the return air duct 17 and the evaporator 4d and is removed through the drain hole 19a. Distributes to frost water trays and defrost water tanks.

このように、還気ダクト１７の内部に給気ダクト１８を配置するようにしたので、給気ダクト１８の外面が直接外気と接触することはなく、給気ダクト１８の断熱性能を低下させても給気ダクトの結露の発生を防止することができる。   As described above, since the air supply duct 18 is arranged inside the return air duct 17, the outer surface of the air supply duct 18 is not in direct contact with the outside air, and the heat insulation performance of the air supply duct 18 is reduced. Also, the occurrence of condensation in the air supply duct can be prevented.

また、給気ダクト１８の下方に結露水を受容するためのドレン受け１９を設けたので、給気ダクト１８の外面が結露した場合に結露水をドレン受け１９によって受容することができ、給気ダクト１８の断熱処理をなくすことができるという利点がある。   Further, since the drain receiver 19 for receiving the dew condensation water is provided below the air supply duct 18, the dew condensation water can be received by the drain receiver 19 when the outer surface of the air supply duct 18 condenses. There is an advantage that the heat insulation treatment of the duct 18 can be eliminated.

尚、前記第１、第２及び第３の実施形態では、冷却ユニット４の空気吸入口４ｇ及び空気吐出口４ｈとショーケース本体１の空気流出口２ｅ及び空気流入口２ｆをそれぞれ還気ダクト５，１２，１７及び給気ダクト６，１３，１８によって接続するようにしたものを示したが、冷却ユニット４の空気吸入口４ｇ及び空気吐出口４ｈを隣接して配置するとともに、空気流出口２ｅ及び空気流入口２ｆを隣接して配置し、図１６に示すように、還気ダクト２０及び給気ダクト２１を隣り合うように一体に形成して断熱材２０ａによって覆うようにしてもよい。この場合、還気ダクト２０及び給気ダクト２１が一体に形成されているので、還気ダクト２０及び給気ダクト２１をそれぞれ接続する必要はなく、冷却ユニット４の接続作業を更に容易に行うことができる。また、還気ダクト２０及び給気ダクト２１をそれぞれ断熱処理を行う必要はなく、製造コストの低減を図ることができる。   In the first, second and third embodiments, the air inlet 4g and air outlet 4h of the cooling unit 4 and the air outlet 2e and air inlet 2f of the showcase body 1 are connected to the return air duct 5 respectively. , 12, 17 and the air supply ducts 6, 13, 18 are shown, but the air inlet 4g and the air outlet 4h of the cooling unit 4 are disposed adjacent to each other, and the air outlet 2e. Further, the air inlet 2f may be disposed adjacently, and as shown in FIG. 16, the return air duct 20 and the air supply duct 21 may be integrally formed so as to be adjacent to each other and covered with the heat insulating material 20a. In this case, since the return air duct 20 and the supply air duct 21 are integrally formed, it is not necessary to connect the return air duct 20 and the supply air duct 21, and the connecting operation of the cooling unit 4 can be performed more easily. Can do. Moreover, it is not necessary to heat-insulate the return air duct 20 and the air supply duct 21, respectively, and the manufacturing cost can be reduced.

A refrigeration cycle may be constituted using brine or the like, or a refrigeration cycle may be constituted by a Stirling refrigerator. In this case, the cooling system of the refrigeration equipment can be changed by changing the cooling unit, and a suitable cooling system can be adopted as necessary.

また、前記第１及び第３の実施形態では、レバー部材７ａ、係合部材７ｂ及びフック部材７ｃからなる着脱機構７によって還気ダクト５，１７及び給気ダクト６，１８を着脱自在に接続するようにしたものを示したが、図１７に示すように、ダクト２２の接続部にフランジ２３を設け、フランジ２３に設けられた孔２３ａにネジ２３ｂを螺合することにより着脱機構を構成してダクト２２を接続したり、図１８に示すように、ダクト２４の接続部の一方に可撓性を有するフック部材２５に係合部２５ａを設け、他方に係合部が係合可能な受部材２６を設けることにより着脱機構を構成し、フック部材２５の先端を受部材２６に差込むようにして着脱自在に接続するようにしてもよい。   In the first and third embodiments, the return air ducts 5 and 17 and the air supply ducts 6 and 18 are detachably connected by the attaching / detaching mechanism 7 including the lever member 7a, the engaging member 7b, and the hook member 7c.
