Description

[Detailed Description of the Invention] The present invention relates to a frozen/refrigerated open case, and particularly relates to a see-through structure on the side of the case.

In this type of case, an inner box is assembled at a certain distance within an outer box made of a heat insulator with a roughly U-shaped cross section, and an air path is created between the inner box and the outer box from the bottom to the back through the ceiling. At the same time, a ventilator and a cooler are arranged in this air passage so that the opening on the front side of the case is covered with a cold air curtain.

FIG. 1 shows an example of this type of case from the side.

The side ends of the case body 1 are closed by side plates 2, and usually, the front area of the side plates 2 at a height corresponding to the display area inside the case is cut out in the depth direction.
The inside of the case can be seen even from the side of the case. A transparent plate 4 made of glass or the like is usually fitted into the notch of the side plate 2 using a decorative cover 3 attached to cover the surface thereof.

However, due to the temperature difference between the inner and outer surfaces of the transparent plate 4, dew tends to form on the outer surface, especially when the temperature is high in summer. However, with the above-mentioned mounting structure of the see-through plate 4, the moisture that has been deposited on the see-through plate 4 flows down along the surface of the see-through plate 4, and furthermore, passes through the decorative cover 3 and falls onto the floor where the show case is installed, wetting the floor on the front side of the show case. There is a drawback.

In addition, this type of open-show case has the drawback that air curtain irregularities tend to occur in the air curtain portions on both sides of the case, and cold air or outside air tends to enter.

The present invention aims to provide a frozen/refrigerated open storage case that eliminates these drawbacks.

The present invention provides an open freezer/refrigerator case having side plates on both sides in which the front part of the side plate is cut out in the depth direction over an area of a predetermined height. A see-through plate is provided that can be seen through at least from the outside using a It is characterized by extending slightly forward or at the same level as the line segment connecting the front part of the mouth and the front part of the cold air suction port.

The present invention has a structure in which a see-through plate is attached to the inner wall of the side panel, but this mounting structure also has the function of draining moisture from dew formed on the outer surface of the see-through plate and the rectifying function of the air curtain. It is characterized by:

Examples of the present invention will be described below.

FIG. 2 is a longitudinal cross-sectional view of the refrigerated/freezer open case according to the present invention, and FIG. 3 is an exploded view of the side plate of the case.

Referring to FIG. 2, an inner box 6 is assembled into an outer box 5 made of a heat insulator, and the space between them forms a ventilation path from the bottom to the ceiling via the back. A ventilation fan 7 and a cooler 8 using a refrigerant evaporator are installed in this ventilation path, and a cold air curtain flows from a cold air outlet 9 provided at the front end of the ceiling to a cold air intake port 10 provided at the front end of the bottom. is formed. The side plate 2 attached to the side end of the case body 1 is provided with a substantially U-shaped notch in the front area corresponding to the display section inside the case, and a see-through plate is provided on the inner wall of the side plate 2 to cover this notch. 4 is screwed on. 11 is a bottom display board, 12 is a display shelf board, and 13 is a drain port connected to an existing drain pipe.

Referring to FIG. 3, the viewing plate (4) is attached via a U-shaped spacer 14 made of metal or resin. As the transparent plate 4, in addition to a transparent plate made of resin or glass, a pair of glass made by combining two transparent plates, a so-called magic mirror that can be seen only from the outside may be used, and the display effect can be improved. can. Holes 41 for screw insertion are provided at appropriate intervals on the peripheral edge of the transparent plate 4, and similar holes 141,
21 are provided.

FIG. 4 is a sectional view taken along the line A--A in FIG. 2, and as is clear from this figure, the transparent plate 4 is attached separated from the inner wall of the side plate 2 by the spacer 14. In this way, the gap formed between the transparent plate 4, the spacer 14, and the inner wall of the side plate 2 at the lower end of the transparent plate 4 acts as a drainage channel for water droplets when dew forms on the outer surface of the transparent plate 4. Further, the hole 41 for a screw provided in the transparent plate 4 has a hole 41 for a screw.
It is formed so that the head of the head is embedded.

5 and 6 are diagrams showing other examples of the portion shown in FIG. 4, respectively.

In the example shown in FIG. 4, a flange 142 is formed on the outer periphery of the spacer 14 to facilitate positioning of the see-through plate 4, but basically the spacer 14
4 may be simplified into a U-shaped flat plate, which is shown in FIG. FIG. 6 shows an improved version of the spacer shown in FIG. 4, in which a U-shaped portion 144 into which the edge of the transparent plate 4 can fit is formed on the outer periphery of the spacer 14, so that the transparent plate 4 and the spacer 14 are integrated. This makes it easy to attach the side plate 2 to the side plate 2.

Referring again to FIG. 2, the transparent plate 4 is installed so that its front end is aligned with the line segment connecting the front part of the cold air outlet 9 and the front part of the cold air intake port 10, or extends slightly forward. It will be done. In this way, the front end of the transparent plate 4 acts as a rectifying plate at the side end of the air curtain flow, and prevents cold air leakage or outside air intrusion that conventionally occurs due to irregular flow at the side end of the air curtain flow. be able to. Furthermore, since the front end of the drainage channel formed by the above-mentioned transparent plate 4, spacer 14, and side plate 2 extends to above the cold air suction port 10, the water flowing therethrough is transferred to the cold air suction port 1.
0 into the bottom ventilation passage, and is drained from the drain port 13.

As is clear from the above explanation, according to the present invention, it is possible to prevent cold air leakage or intrusion of outside air from the air curtains at both ends of the case, improving cooling efficiency and thereby improving the operation of the cooling circuit. It is possible to save energy by lowering the rate. Furthermore, even if dew forms on the outer surface of the see-through plate 4, the moisture can be drained out of the regular drainage port without flowing out of the case and spreading to areas where people can easily see it.

It goes without saying that the frozen/refrigerated open case according to the present invention is not limited to the illustrated type.
