Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a show case with a glass window provided with a cooling chamber in the lower part of the storage chamber, the width of which is smaller than the width of the storage chamber.

Structure of a conventional example and its problems FIGS. 1 to 3 show a conventional show case with a glass window. The configuration of this conventional example will be explained below with reference to FIGS. 1 to 3.

In the figure, 1 is a show case with a glass window. Reference numeral 2 denotes a storage room installed in the upper part of the main body, with multi-layer transparent walls 4 installed on three sides between pillars 3 set up in the square part of the main body, and a door (not shown) attached to the remaining one side so as to be openable and closable. It is composed of: A cooling chamber 5 is provided in the lower part of the storage chamber 2, and a machine room 6 is provided in the lower part thereof. And the width of the cooling room 5 and the machine room 6 (second
The width of the storage chamber 2 (the length in the left-right direction in the figure) is
2A (as shown in Figure 3)
I'm keeping it small. The cooling chamber 5 is provided with a cooler 7 and an internal blower 8. Reference numeral 9 is a heat insulating container with an open top surface, which houses the cooler 7 and the internal blower 8. Reference numeral 10 denotes a bottom plate of the storage chamber 2, which covers the upper surface of the heat insulating container 9 and partitions the cooling chamber 5 and the storage chamber 2. This bottom plate 10 consists of an upright piece 11 that comes into contact with the upper end of the heat insulating container 9, and a horizontal part 12, and this horizontal part 12 has square discharge ports 13 on the windward and leeward sides of the internal blower 8, and a suction inlet. Mouth 14
is formed. The machine room 6 includes an electric compressor 15, a condenser 16, and a cooling blower 17.
has been established. Reference numeral 18 denotes an evaporating dish that collects the defrosting water from the cooler 7 and evaporates it. Reference numeral 19 denotes a receiving frame, which is placed on a receiving metal fitting 21 attached to the upper end of the heat insulating container 9 and the upper end of the chassis 6 constituting the framework of the machine room 6. The lower end of the multilayer transparent wall 4 and the bottom plate 10 are placed on this receiving frame 19. Next, the configuration near the discharge port 13 will be explained. The inner end 19' of the receiving frame 19 is located closer to the multi-layer transparent wall than the opening end of the discharge port 13 on the multi-layer transparent wall 4 side, and is located between the inner end of the receiving frame 19 and the discharge port 13. There is a distance B to the inner opening end, and a dimension C is provided in the width direction of the upper end of the heat insulating container 9 (both are the third
(Illustrated in the figure). The same applies to the structure near the suction port 14.

Next, the flow of cold air will be explained.

The cold air discharged from the internal blower 8 rises along the inner surface of the heat insulating container 9 and is discharged upward into the storage chamber 2 from the discharge port 13. Then, it rises along the inner surface of the multilayer transparent wall 4, and the storage chamber 2
reaches the top surface 20 of , and is further sucked toward the suction port 14 .

However, in the above conventional example, since the width of the cooling chamber 5 is smaller than the width of the storage chamber 2 on one side by the dimension A, the widthwise dimension C of the upper end of the heat insulating container a is smaller than the width of the multilayer transparent wall 4 of the discharge port 13. Since it is located inward from the side opening end, the opening dimension B through which the discharged cold air passes is narrow. Similarly, the same can be said about the suction port 14 side. Therefore, since the cold air discharged by the internal blower 8 is throttled by this dimension B, the discharge air volume is small, and since it is also throttled on the suction side,
The amount of cold air circulating inside the refrigerator was low, resulting in poor cooling performance. In addition, since there are only the receiving frame 19 and the receiving metal fitting 21 at the bottom of the multi-layer transparent wall 4, the surface temperature of the receiving metal fitting 21 decreases through the receiving frame 19 due to heat conduction from the multi-layer transparent wall 4, and dew condensation occurs. Occur. There was a drawback that this condensed water dripped onto the floor.

Purpose of the invention The present invention eliminates the drawbacks of the conventional example described above, and improves the cooling performance by increasing the amount of cold air circulated, and also improves the perspiration performance by reducing heat conduction to the receiving frame and the receiving fitting. The purpose is to improve the quality of the products.

Structure of the invention In order to achieve the above object, the present invention provides a bottom plate of a storage chamber that covers the upper surface of a heat-insulating container and has a cold air outlet and an intake in the vicinity of a multilayer transparent wall, and a bottom plate of a storage chamber that covers the upper surface of an insulated container and has an outlet and an inlet for cold air. It is located on the multi-layer transparent wall from the open end of the multi-layer transparent wall side, and has a protrusion that protrudes outward from the upper end side of the heat-insulating container on which the receiving frame is placed, and has excellent cooling performance and perspiration performance. The aim is to improve

DESCRIPTION OF THE EMBODIMENTS The structure of an embodiment of the present invention will be described below with reference to FIGS. 4 to 6, but the same numbers will be given to the same structures as the conventional ones and detailed explanation thereof will be omitted.

22 is a protrusion formed by protruding the upper end of the heat insulating container 9 to the outside; the receiving frame 19 is placed on this protruding part 22;
It is placed on top of 1. The multilayer transparent wall 4 is placed on the receiving frame 19 as in the conventional case.

Next, the configuration near the discharge port 13 will be explained.

After forming the protrusion 22, the chassis 6'
The distance in the width direction between the upper end and the slope 23 of the heat insulating container 9 is C (dimension in the width direction of the upper end of the conventional heat insulating container 9).
The inclined surface 23 is inclined in a direction that makes the slope gentler, using point E (shown in FIG. 6) as a fulcrum until the point E (shown in FIG. 6) is reached. Even in this case, it is possible to ensure the same insulation properties as the conventional one, and therefore the inner end 19' of the receiving frame 19 placed on the upper end of the heat insulating container 9 and the discharge port 1 can be secured.
The distance from the inner open end of No. 3 can be increased to D, where D>B. Further, the configuration near the suction port 14 is also similar.

Therefore, since the opening areas of the discharge and suction ports are expanded, the amount of cold air circulated increases, and the cooling performance is improved. Furthermore, since the protrusion 22 of the heat insulating container 9 is formed at the lower part of the receiving frame 19, heat conduction from the multi-layer transparent wall 4 can be reduced, so the surface temperature of the receiving fitting 21 does not drop, thereby improving perspiration performance. can be improved.

Effects of the Invention The present invention has the above-mentioned configuration, and provides the following effects.

By forming a protrusion that protrudes outward at the upper end of the insulated container on which the receiving frame is placed, the volume of the cooling chamber can be increased, and the opening area of the discharge and suction ports can be expanded. The amount of circulation can be increased and cooling performance can be improved. Furthermore,
Since the heat conduction from the multilayer transparent wall through the receiving frame can be reduced, the surface temperature of the receiving fitting does not decrease, so that perspiration performance can be improved.
