FIG. 4 shows an example of this type of showcase.
And a showcase 31 as shown in FIG.
The showcase 31 is formed by a heat insulating box 33 having an opening 32 for taking in and out a product above. The opening 32 is covered with a roof-shaped hood 34, and a transparent slide door 35 that can be opened and closed before and after the hood 34. Is provided. Product display portions 36 are formed at intervals inside the heat insulating box 33, and a plurality of basket-shaped buckets 37 are stored therein. The floor of the commodity display section 36 is formed in a double structure, and has a cool air circulation duct 40 having a cooler 38 and a blower 39.
Is provided. Both ends of the circulation duct 40 are connected at the rear end to the cool air outlet 41 and at the front end to the cool air inlet 42. The cool air cooled by the cooler 38 is supplied from the cool air outlet 41 to the near side. It blows out to the merchandise display section 36 to maintain the merchandise display section 36 at a predetermined cooling temperature, and
It is sucked into the circulation duct 40 from 2 and circulates through this path by the action of the blower 39. A refrigeration component 43 is built in the lower part of the heat insulation box 33 of the showcase 31, and air is introduced from a punching hole formed in the front kick plate 44 for the introduction of outside air by the action of a condenser fan (not shown). The air is sucked, and the waste heat air is discharged from the rear side of the showcase 31.

[0004]

By the way, in such a conventional refrigerator built-in type showcase 31, dew condensation water adheres to the windshield (such as the sliding door 35 of the hood 34), and eventually grows into droplets. In some cases, the water flowed down the floor of the case and accumulated on the floor. In addition, windshield (hood 34
Water may adhere to the sliding door 35, etc.), and eventually grow into droplets, soak into the heat insulating box 33 through a gap in the exterior of the case, and corrode the inside of the heat insulating box 33 in some cases. Then, in order to prevent the above, a structure in which dew condensation water is guided to the drain tank has been developed, but the number of parts is increased and the cost is high.

Accordingly, an object of the present invention is to provide an inexpensive refrigerator-incorporated showcase that has a simple structure and prevents the occurrence of dew condensation by constantly creating a flow of wind on the breeze shield.

[0006]

In order to solve the above-mentioned problems, according to the present invention, there is provided a heat insulating box having an opening for taking in and out of a product, and a space formed inside the heat insulating box. A refrigerator and a blower are provided in the underfloor duct between the product display part and the refrigerator built-in type showcase that cools the opening by covering the opening with cool air, and forms a gap between the heat insulating box and the exterior panel. The air passage, the lower end of the air passage is connected to the outside air introduction path for heat exchange with the condenser of the refrigerator, the upper end of the air passage is connected to a punching hole formed in a handrail rail located outside the windshield, In addition, waste heat of the refrigerator is blown out from a punching hole of one handrail rail, and the blown waste heat and ambient air are sucked in from a punching hole of the other handrail rail. Further, the relationship between the waste heat blow-out side of the punching holes of the handrail rail and the waste heat / peripheral air suction side coincides with the cool air blow-out side and the cool air suction side in the cooling unit in the showcase storage, and the wind circulation direction. Is characterized by the same.

[0007] By adopting the above configuration, since the waste heat air of the refrigerator flows near the windshield, dew condensation can be prevented. In addition, since the circulation direction of the cold air and the waste heat air was the same, the waste heat air of the refrigerator blown out from the punching hole of the railing rail on one side was pulled by the air curtain inside the refrigerator, and was drawn on the top plate of the case. The air flows along the rail and is sucked into the air passage together with the surrounding air from the punching hole of the other handrail rail. Therefore, even without the sliding door of the hood, the waste heat air is smoothly circulated and does not collide with the cool air, so that no turbulence is generated and the cooling efficiency of the showcase is not hindered.
