Description

本発明は、例えばスーパーマーケットや大型コンビニエンスストア等の食品売り場において、生鮮食料品や冷凍食品等を陳列するために用いられる冷凍冷蔵ショーケースおよびその設置方法に関する。   The present invention relates to a frozen and refrigerated showcase used for displaying fresh food, frozen food, and the like in a food department such as a supermarket and a large convenience store, and a method for installing the same.

例えばスーパーマーケットや大型コンビニエンスストア等の食品売り場に配置される従来の冷凍冷蔵ショーケースは、いわゆる別置型ケースと呼ばれ、通常、圧縮機、凝縮器、減圧装置、凝縮器用送風機を含む冷凍装置を、顧客から見えない場所、例えばバックヤードの奥、あるいは食品売り場と同一の建屋内の、食品売り場から離れた場所に設置するのが一般的である。この場合、冷凍装置と冷凍冷蔵ショーケースとの間には、冷媒を循環させるための冷媒配管(例えばサクション管やリキット管等)や、冷凍冷蔵ショーケースに電力を供給するための電気配線を延在させる必要がある。これらの冷媒配管や電気配線は、通常、床面に形成されたピット内を通じて延在するように設けられ、冷凍冷蔵ショーケースは、食品売り場にてピットの上方を覆うように載置され、ピット内の冷媒配管は、冷凍冷蔵ショーケースに形成した冷媒配管口を通じてショーケース本体内の冷却装置に接続されるとともに、ピット内の電気配線は、冷凍冷蔵ショーケースに形成した電線貫通口を通じてショーケースの電気配線と接続される。   For example, a conventional freezing and refrigeration showcase placed in a food department such as a supermarket or a large convenience store is called a so-called stand-alone case, and usually includes a compressor, a condenser, a decompression device, and a refrigerator for a condenser. It is generally installed in a place that is not visible to the customer, for example, in the back of the backyard or in the same building as the food department, away from the food department. In this case, a refrigerant pipe (for example, a suction pipe or a rekit pipe) for circulating the refrigerant and an electric wiring for supplying power to the freezer / refrigerator showcase are extended between the refrigeration apparatus and the freezer / refrigerator showcase. It is necessary to exist. These refrigerant pipes and electrical wiring are usually provided so as to extend through the pit formed on the floor surface, and the freezer / refrigeration showcase is placed so as to cover the top of the pit at the food department, The refrigerant piping inside is connected to the cooling device in the showcase body through the refrigerant piping port formed in the refrigerated refrigerated showcase, and the electrical wiring in the pit is connected to the showcase through the wire through hole formed in the refrigerated refrigerated showcase Connected to the electrical wiring.

また、従来の冷凍冷蔵ショーケースは、例えばフォークリフト等で持ち上げて搬送したり、配管を設置したりする際の作業をしやすくする等の理由から、ショーケース本体の下面の左右両側端部に一対の台脚を設けて、食品売り場の床面との間に所定高さ寸法をもつ床上空間を形成するのが一般的である。しかしながら、前記台脚は、特に冷凍冷蔵ショーケースの下面と床面のピット上方領域との間に存在するピット上方空間を有効に利用する観点から、ピットの配設位置および配設寸法を考慮して配設形状の適正化を図った公知文献は見当たらない。   In addition, a conventional freezer / refrigerated showcase is paired with both left and right end portions of the lower surface of the showcase main body for the purpose of facilitating the work when lifting and transporting it with a forklift or the like or installing a pipe. In general, a floor space having a predetermined height is formed between the floor and the floor of the food department. However, the pedestal takes into account the location and dimensions of the pits, particularly from the viewpoint of effectively using the space above the pit that exists between the bottom surface of the refrigerated showcase and the area above the pit on the floor surface. There is no known document that attempts to optimize the arrangement shape.

従来の冷凍冷蔵ショーケースの台脚としては、例えば特許文献1に、低温ショーケースの本体の下面の左右両端部のそれぞれに、床面のピットの上方領域を横切るようにショーケース本体の前後方向に連続して延びる単一の台脚を固定連結した構成が開示されている。   As a pedestal of a conventional freezer / refrigerated showcase, for example, in Patent Document 1, the front / rear direction of the showcase main body crosses the upper region of the pit on the floor surface at each of the left and right end portions of the lower surface of the low-temperature showcase main body. The structure which fixedly connected the single base leg extended continuously is disclosed.

しかしながら、特許文献1に記載の低温ショーケースのように、床面のピットを横切るようにショーケース本体に台脚(特許文献1に示されている台脚と類似する配設形状として、図5および図6の台脚68を参照。)を設けると、ショーケース本体の下面と、床面のピットの上方領域との間に存在するピット上方空間が、ショーケース本体の左右両端部に取り付けた一対の台脚によって仕切られてしまうため、ショーケース本体の下面に位置するピット内に冷媒配管や電気配線を新たに配設するための新設作業や、既にピット内に配設されている、冷媒配管からの漏れ等の不具合の点検、冷媒配管の交換等のメンテナンス作業を行なう場合に、ピット内の冷媒配管等を、作業者が視認できるピット上方空間の位置まで持ち上げることは難しく、作業性が劣るという問題があった。   However, like the low-temperature showcase described in Patent Document 1, a pedestal (as an arrangement shape similar to the pedestal shown in Patent Document 1 is shown in FIG. And the pedestal 68 in FIG. 6), the pit upper space existing between the lower surface of the showcase body and the upper area of the pits on the floor surface is attached to the left and right ends of the showcase body. Because it is partitioned by a pair of pedestals, new work for newly installing refrigerant piping and electrical wiring in the pit located on the lower surface of the showcase body, or refrigerant already installed in the pit When performing maintenance work such as checking for defects such as leaks from pipes or replacing refrigerant pipes, it is difficult to lift the refrigerant pipes in the pits up to the space above the pits where the operator can see them. , There is a problem that workability is poor.
