Abstract

PURPOSE:To obtain a refrigerated showcase so constructed as to permit the dew condensed on the glass side plate of the showcase to drain off from the inside of the showcase before the condensed water drops on the floor surface. CONSTITUTION:A channeled frame 5 is provided to support the lower ends of glass side plate 4 fixed to the side wall of a showcase for seeing its interior therethrough and formed into the shape of a trough which serves as a dew receiving tray, a dew drain hole 5a is formed in wall of the frame on the inner showcase side and a dew receiving guide 5b is formed on the upper edge of the frame on the outer showcase side along the glass side plate projecting upwardly and obliquely from the frame edge. L-shaped spacers 6 are provided at a plurality of front and rear places arranged at intervals to retain a water rain passage 5c in the frame channel between the bottom surface and outer surface of the glass side plate and the inner surface of the frame, the water condensed on the outer surface of the glass side plate is allowed to flow into the frame channel and the water runs through the dew drain hole 5a on a bottom plate 8 in the showcase and drained off from a water drain hole 8a.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerating showcase in which a glass side plate for seeing through a refrigerator is fitted on a side wall of a case body, and more particularly to a drainage structure for dew condensed on the glass side plate.

[0002]

2. Description of the Related Art As a refrigerated open showcase, a structure in which a side plate of transparent glass is fitted on the side wall of the case body has been conventionally used so that the products displayed in the case can be seen from the side of the case. Has been done. FIG. 3 shows the entire structure of such a refrigerated showcase. In the figure, 1 is a case body with an open front, 2 is a product display shelf installed in the cabinet, 3 is a heat insulating property that covers the side surface of the case body 1. The side walls 4 and the side walls 3 are notched and fitted into the glass side plate for internal fluoroscopy, and 5 is a grooved frame for supporting the lower end of the glass side plate 5, commonly called a molding.

[0003]

The refrigerated showcase having the glass side plate fitted on the side wall of the case body as described above has the following problems. That is,
If the side wall of the case body that is in contact with the refrigerating space in the refrigerator is composed of a heat insulating wall, almost no condensation will occur, but with the structure in which the glass side plate is fitted to the side wall as described above, the glass side plate is kept cool during the showcase. Dew forms on the outer surface of the container because it is cooled by the cold air inside the container. Moreover, if the condensed dew is left as it is, it will travel down the glass surface and flow down to the floor, which will wet the floor in the store.

The present invention has been made in view of the above points, and by improving the structure of the frame for supporting the lower end of the glass side plate, the above problems are solved and dew droplets condensed on the glass side plate are deposited on the floor surface. It is an object to provide a structure of a refrigerating showcase so that wastewater can be treated as drainage inside the refrigerator before it flows down.

[0005]

In order to achieve the above object, in the refrigerating showcase of the present invention, the grooved frame for supporting the lower end of the glass side plate is formed as a gutter-shaped body which also serves as a dew tray, and The frame shall be constructed by opening a dew drainage hole in the wall surface on the inside side of the frame. Further, the frame in the above configuration can be configured by adding the following additional requirements.

(1) A structure in which a dew receiving guide is formed at the upper edge of the outer side of the frame so as to project obliquely upward along the glass side plate. (2) In the groove of the frame, an L-shaped spacer for maintaining a gap as a drainage passage between the bottom surface and outer surface of the glass side plate and the frame is arranged at a plurality of front and rear positions.

(3) A structure in which a waterproof seal is provided between the frame and a spacer interposed at the front and rear end positions in the frame.

[0008]

According to the above construction, the dew that has condensed on the outer surface of the glass side plate during the cold storage operation of the refrigerated showcase is transmitted along the glass surface and flows into the groove of the frame which also serves as the dew tray, and is opened on the wall surface of the frame. After flowing down on the bottom plate in the refrigerator through the dewatering hole, the waste water is drained from the drain hole of the bottom plate.

[0009]

Embodiments of the present invention will be described below with reference to FIGS. In the figure, the same members corresponding to those in FIG. 3 are designated by the same reference numerals. In the configuration of the illustrated embodiment, the metal grooved frame 5 that fits and supports the lower end of the glass side plate 4 is made as a gutter-shaped body having a U-shaped cross-section that also serves as a dew tray, and its inside side. At the lower part of the wall surface, a dew drain hole 5a is opened, and at the upper edge of the outside side of the refrigerator, there is provided a dew receiving guide 5b which is formed to project obliquely upward along the glass side plate 4. Also, frame 5
In the groove of, the L-shaped spacers 6 are divided into a plurality of front and rear portions so as to hold the glass side plate 4 while leaving a gap to be the exposed water passage 5c between the bottom surface and the outer surface of the glass side plate 4 and the inner surface of the frame. It has been deployed. In particular, a seal member 7 provides a waterproof seal between the frame 5 and the end of the spacer 6 interposed at the front and rear ends of the frame 5.

With such a structure, when dew condensation occurs on the outer surface of the glass side plate 4 during the cold-keeping operation of the showcase, the dew drop W drips on the glass surface and flows into the groove of the frame 5 through the above-mentioned gap, and then the dew water It flows through the passage 5c, comes out from the dew drainage hole 5a, and flows down onto the bottom plate 8 in the refrigerator. On the other hand, a drain drain hole 8a is opened in the bottom plate 8 in the refrigerator, and the dew water is drained together with the drain generated inside the refrigerator through the drain drain hole 8a. In this case, the dew receiving guide 5b formed on the outer side of the frame 5 catches the dew drop W dripping from above, so that there is no risk of dew overflowing onto the floor surface, and the dew drop inside the groove of the frame 5 does not occur. Since a waterproof seal is provided between the spacer 6 and the frame 5 which are interposed at the front and rear ends,
Dew water does not leak from the front and rear ends of the frame 5.

[0011]

Since the refrigerated showcase of the present invention is constructed as described above, the dew condensed on the guide side plate flows into the groove of the frame which also serves as the dew tray and is drained to the bottom plate in the refrigerator. . Therefore, it is possible to prevent the trouble that the dew condensation water drips on the floor as it is and wets the floor surface.
