Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As a refrigerated showcase facility that allows easy and quick replenishment of merchandise to a refrigerated showcase installed in a sales floor of a store, it is connected to a refrigerated warehouse for storing merchandise built inside a store building. It is known from Japanese Utility Model Publication No. 51-30215 that a refrigerated showcase (open showcase) is installed on the sales floor side of the store so that a cart for displaying products can be directly carried into the showcase through the opening of the refrigerated warehouse. is there.

In such a refrigerating showcase facility, a part of the cool air from the refrigerating warehouse is taken into the refrigerating showcase and a cool air curtain is blown out from above in front of the refrigerating showcase. It is collected in the front part with a built-in fan installed in the lower part of the front, and is then circulated to return to the cold storage via the floor of the showcase.

[0004]

By the way, when the above refrigerated showcase equipment is installed in a store, the following problems arise. That is, in general, when constructing a refrigerated warehouse, in order to enhance the heat insulation performance with the outside and suppress the heat loss as much as possible, not only the peripheral walls and ceiling walls of the warehouse but also the floor surface side thereof is heat-insulated. I am trying to apply it. However, the floor surface of the in-store sales floor where the refrigerated showcase is installed is usually not subjected to such heat insulation treatment, and floor building materials such as P tiles are simply laid on the foundation surface of concrete, mortar, etc. .

Therefore, if the refrigerated showcases are installed in the refrigerated warehouse in such a state and installed and used in the in-store sales floor, the floor area on which the refrigerated showcases are installed is in direct contact with the cold air inside the showcases. It is cooled to a low temperature. As a result, a large temperature difference occurs with the floor area on the in-store sales floor side, which causes a large amount of heat to transfer from the in-store sales floor to the floor and enter the showcase. In addition to increasing heat loss, the floor surface around the refrigerated showcase is cooled to a low temperature and a large amount of dew condensation occurs, causing problems such as wetting the floor of the sales floor passage.
In particular, if the refrigerating warehouse 1 and the refrigerating showcase 3 are of a freezing type, this tendency becomes large.

The present invention has been made in view of the above points, and is intended for the refrigerating showcase equipment described above to solve the above-mentioned problems to reduce the heat loss on the cold insulation surface, and also at the in-store sales floor. 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 surface of a refrigerator.

[0007]

In order to achieve the above object, in a refrigerating showcase facility of the present invention, a refrigerating warehouse and an installation of a refrigerating showcase connected to the refrigerating warehouse and installed on the in-store sales floor side. A heat insulating layer shall be buried under the floor of the building including the area. Then, a flat floor surface without steps is formed between the refrigerating warehouse and the refrigerating showcase on the heat insulating layer in the above-mentioned structure, and this floor surface is constituted by the floor board of the baby cage structure and the lower surface side thereof. In addition to defining a utility space for accommodating refrigerant piping, etc.,
There is a structure in which a drain drainage 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 bottom surface of the floor plate.

[0008]

With the above structure, not only the cold air inside the refrigerating warehouse for storing goods, but also the cold air heat inside the refrigerating showcase which is installed in the refrigerating warehouse and installed on the store floor side is buried under the floor. The heat insulation layer shields the heat and prevents the heat from escaping by transferring heat to the surrounding floor surface. This significantly reduces the heat loss of the refrigerated showcase compared to the case where the floor surface is not heat-insulated, and the condensation on the floor of the in-store sales floor side is caused by cold air heat, and the sales floor passage due to this condensation Wet and dirt can be satisfactorily avoided.

Further, by forming a flat floor surface without steps between the refrigerating warehouse and the refrigerating showcase on the heat insulating layer, the display cart can be carried in between the refrigerating warehouse and the showcase. ， Easy to carry out, and by constructing the floor surface with the floor board of the child structure, the space defined on the lower surface side can be utilized as a utility space for accommodating refrigerant pipes. Further, the drain drainage pit provided under the heat insulating layer is provided for drainage of condensed water generated in the refrigerated warehouse, the interior of the showcase, and the products on display in the showcase warehouse from the floor through the pit. It plays the role of draining outside. By installing a drain antifreezing heater on the lower surface side of the floor plate, the drain can be prevented from freezing and drain water can be smoothly drained.

Here, the refrigerating showcase 3 is provided with a ventilation duct for blowing cold air curtains, which communicates with the inside of the refrigerating warehouse 1 on the ceiling part of the self-standing case body 3a whose front and rear surfaces are open, and the cooling device 3b (refrigerator 3b). The evaporator 3), the fan 3c are housed therein, the fan 3d for sucking the air curtain is built in the front part of the lower front portion, and the product display shelf 3e is attached to the upper part of the inside of the case, and the case body A curtain 3f that partitions the refrigerating warehouse 1 from the back of the refrigerating warehouse 3a is hung so that the commodity display cart 4 can be freely carried into the showcase from the refrigerating warehouse 1.

With such a structure, when the refrigerating showcase 3 is kept cold, a part of the cold air in the refrigerating warehouse 1 is taken into the ceiling duct of the showcase and further cooled to a lower temperature by the cooler 3b, and then the fan 3c. Thus, the air is blown to the front opening surface of the case body 1 to form a cool air curtain. In addition, the cool airflow of the air curtain is sucked into and collected by the front part that has a built-in fan 3d. Circulating air is blown so as to recirculate, and the cold air blowing suppresses the inflow of outside air heat into the warehouse, and the product display shelf 3
e, keep the products arranged in the display cart 4 cool.

Here, according to the present invention, a heat insulating layer indicated by reference numeral 5 is buried under the floor surface of the building including the installation surface areas of the refrigerating warehouse 1 and the refrigerating showcase 2. The heat insulating layer 5 is made of, for example, a hard foam resin,
When the refrigerated warehouse 1 is constructed, it is subjected to floor surface treatment before construction.
Then, for example, concrete is poured on the heat insulating layer 5 to form a flat floor surface 6 having no step between the refrigerated warehouse 1 and the refrigerated goods 3.

With this structure, the heat insulating layer 5 shields heat between the floor surface 6 of the refrigerating warehouse 1 and the refrigerating showcase 3 and the external floor surface, so that heat can be transferred to the floor and heat from the surroundings can be prevented. In addition, it is possible to favorably prevent the floor surface around the showcase from being dewed by the cold air heat to wet or stain the passage.
