BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerated showcase facility which is installed in a large store such as a supermarket to exhibit and sell frozen and refrigerated products.

[0002]

2. Description of the Related Art As a refrigerated showcase facility that can easily and promptly replenish products to a refrigerated showcase installed at a store floor of a store, it is connected to a refrigerated warehouse for product storage constructed inside a store building. A refrigerated showcase (open showcase) is installed on the sales floor side of the store, and a product display cart can be directly loaded into the showcase through the opening of the refrigerated warehouse, which is well known in Japanese Utility Model Publication No. 51-30215. is there.

In such a refrigerated showcase facility, a part of cold air is taken from a refrigerated warehouse into a refrigerated showcase, and a cold air curtain is blown out from the top of the refrigerated showcase from above. It is collected at the front part with a built-in fan provided at the lower part of the front, and is further circulated through the showcase floor to return to the refrigerated warehouse.

[0004]

When the above-mentioned refrigerated showcase equipment is installed in a store, the following problems arise. That is, in general, when constructing a refrigerated warehouse, in order to increase the heat insulation performance between the outside and the heat loss as much as possible, not only the peripheral wall and the ceiling wall of the warehouse but also the floor surface side thereof. To be constructed. However, the floor of an in-store floor where a refrigerated showcase is installed is not usually subjected to such heat-insulating treatment, and merely a floor building material such as a P tile is laid on a foundation such as concrete or mortar. .

Therefore, if the above-mentioned refrigerated showcase is installed in a store and connected to a refrigerated warehouse in this state and used, the floor area on which the refrigerated showcase is installed comes into direct contact with the cold air in the showcase. And cooled to a low temperature. As a result, a large temperature difference is generated between the floor area on the store floor side and a large amount of heat from the store floor side is transmitted to the floor to enter the showcase, thereby causing a refrigerated showcase. In addition to an increase in heat loss, the floor around the refrigerated showcase is cooled down to a low temperature, causing a large amount of dew condensation to occur, causing problems such as wetting the floor of the sales passage.
In particular, when the refrigerated warehouse 1 and the refrigerated showcase 3 are of the freezer type, this tendency is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and aims at solving the above-mentioned problems and reducing heat loss on a refrigerated surface in a refrigerated showcase facility as described above. It is an object of the present invention to provide a refrigerated showcase facility capable of avoiding the occurrence of dew condensation on the floor of a building.

In order to achieve the above object, in the refrigerated showcase equipment of the present invention, the refrigerated warehouse and the installation of the refrigerated showcase connected to the refrigerated warehouse and installed on the sales floor in the store are installed. A heat insulation layer shall be buried under the floor of the building including the area. Then, on the heat insulating layer in the above configuration, a flat floor surface having no step between the refrigerated warehouse and the refrigerated showcase shall be formed, and this floor surface is constituted by a floor plate having a pen-shaped structure, and the lower surface side thereof is formed. A utility space for accommodating refrigerant pipes, etc.
There is a configuration in which a drain drain pit communicating with the utility space is provided below the heat insulating layer through a drain hole opened in the heat insulating layer. Further, it is preferable that a drain freeze prevention heater is laid on the lower surface of the floor plate.

[0008]

According to the above construction, not only the cold air inside the refrigerator store for storing goods, but also the cool air heat in the refrigerator showcase warehouse which is connected to the refrigerator store and installed at the store side is buried under the floor. The heat insulation by the heat insulating layer prevents the heat from being transmitted to the surrounding floor surface and escaping. As a result, the heat loss of the refrigerated showcase is greatly reduced as compared with the case where the floor is not heat-insulated, and dew condensation due to cold air is generated on the floor on the side of the sales floor in the store, and the store passage due to the dew condensation. Satisfactorily can be avoided.

[0009] Further, by forming a flat floor surface with no step between the refrigerated warehouse and the refrigerated showcase on the heat insulating layer, the display cart is carried in between the refrigerated warehouse and the showcase. In addition, since the floor can be easily carried out, and the floor surface is formed of a floor plate having a floor structure, the space defined on the lower surface side can be used as a utility space for accommodating refrigerant pipes and the like. In addition, a drain drain pit provided below the heat insulating layer is provided for draining the condensed water generated in the refrigerated warehouse, the inside of the showcase, and the displayed products in the showcase warehouse from the floor through the pit. Plays the role of draining water outside. By arranging a drain anti-freezing heater on the lower surface side of the floor plate, the drain can be prevented from freezing and drain water can be smoothly drained.
