Description

DETAILED DESCRIPTION OF THE INVENTION [Structure of the Invention] (Industrial Application Field) The present invention relates to a showcase in which dew attached to the outer surface of an inner box is guided as drain water to a drain tray.

(Prior Art) In a showcase of this type, for example, a showcase with an upper opening, as shown in FIGS. 3 and 4, an outer body 1 with an upper opening and an inner body arranged inside this outer body 1 are provided. Box 2,
It has a heat insulating layer 3 formed of a heat insulating material arranged between the outer body and the inner box, and is arranged so that the opening / closing doors 4 and 4 can be slid in the opening of the outer body 1. The heat insulating layer 3 disposed between the outer body and the inner box is made by joining two of the side wall layer 5 and the bottom wall layer 6 with the seal tape 7.

(Problems to be solved by the invention) In the above-described upper opening showcase, the inner box and the heat insulating layer are not structurally completely adhered to each other, and when the operation is continued for a long time, the outer box of the inner box is exposed. As a result, the dew flows downward along the outer surface of the inner box and leaks out through the bottom wall layer and the sealing tape, and is disposed in the machine room formed under the bottom wall layer. The electric equipment that has been installed causes electrical troubles when dew that flows downward along the outer surface of the inner box enters the machine room, and the dew leaks as drain water to the outside, and the showcase is installed. There is a problem that the floor is soiled.

The present invention has been made in view of the above-mentioned points, and the dew that flows downward along the outer surface of the inner box is guided to the drain port provided in the bottom wall layer, and is discharged to the drain tray from there to cause an electrical trouble. It is an object of the present invention to provide a showcase that eliminates the occurrence of dust and keeps the installation floor surface clean.

[Constitution of device]

(Means for Solving the Problems) In the showcase of the present invention, the outer body of the upper opening and the inner box arranged in the outer body are heat insulating materials arranged between the outer body and the inner box. The heat insulating layer is formed, and the heat insulating layer is composed of two of a side wall layer and a bottom wall layer, and an annular groove is formed in a portion of the upper surface of the bottom wall layer corresponding to the outer surface of the inner box. It is configured by communicating the annular groove with a drain port provided in the bottom wall layer.

(Operation) In the showcase of the present invention, the dew formed on the outer surface of the inner box flows downward along the outer surface of the inner box, is guided to the annular groove provided on the upper surface of the bottom wall layer, and drains from there. Since it is discharged to the drain tray through the mouth, the drain water does not enter the machine room, cause an electrical trouble, or leak to the outside and pollute the installation floor surface.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, the same members as those in FIG. 4 are designated by the same reference numerals.

In FIG. 1, reference numeral 10 is an annular groove, and this annular groove 10 is formed in a portion corresponding to the outer surface of the inner box 2 on the upper surface of the bottom wall layer 6 of the heat insulating layer 3. Further, the annular groove 10 communicates with a drain port 12 provided in the drain water receiving portion 11 via a guide passage (not shown). An evaporator 13 that constitutes a refrigeration cycle is provided on the inner bottom surface of the drain water receiving portion 11.
And the fan device 14 is arranged.

On the other hand, a machine chamber 15 formed between the bottom wall layer 6 of the heat insulating layer 3 and the outer body 1 is provided with a compressor 16, a condenser 17 and a fan device 18 which form a refrigeration cycle. A drain tray 19 is attached to a portion of the lower surface of the outer body 1 corresponding to the drain water receiving portion 11.

Then, the cold air that has been heat-exchanged by the evaporator 13 is forced by the fan device 14 and guided into the refrigerator to cool the refrigerated items placed in the refrigerator, but if the inside of the refrigerator is kept cold for a long time, Dew adheres to the outer surface of the inner box 2 disposed inside the body, and the adhered dew flows downward along the outer surface of the inner box 2 and is guided to the annular groove 10 provided on the upper surface of the bottom wall layer 6 to form the annular groove. The drain water stored in 10 is discharged to the drain tray 19 through the drain port 12, and therefore the drain water flows through a predetermined passage, so that the drain water enters the machine room,
It will not cause any electrical trouble.

[Effect of device]

As described above, according to the present invention, the dew adhering to the outer surface of the inner box disposed inside the outer body is discharged from the drain port 12 to the drain tray 19 through the annular groove formed on the lower side of the inner box. Therefore, the drain water does not enter the machine room, which may cause electrical troubles or stain the floor of the showcase.
