DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional side view of a flat open showcase of the present invention, and FIG. 2 is a perspective view of the same.

The flat open showcase 1 comprises a box-shaped merchandise display portion 2 having an open top and a pedestal portion 3 for holding the merchandise display portion 2 at an appropriate height, as in the conventional case. The refrigeration unit 15 is accommodated in the pedestal 3. The four side walls 4 of the product display section 2 are
The upper windshield is made of a transparent plate 4a made of glass or the like, and the lower part is made of a panel 4b having a heat insulating function. The upper end and both ends of the transparent plate 4a are provided with struts 5 and upper rails 6 provided at four corners. And is held by.

Furthermore, the bottom plate 2a of the commodity display section 2 is formed in a double structure, and is provided with a cool air circulation duct 9 having a cooler 7 and a blower 8. Both ends of the circulation duct 9 are connected to a cool air outlet 10 and a cool air inlet 11, and the air cooled by the cooler 7 is blown out from the cool air outlet 10 into the product display unit 2, so that the air is cooled. Is maintained at a predetermined cooling temperature, and the circulation duct 9 is
And is circulated through this path by the action of the blower 8.

The cold air outlet 10 and the cold air inlet 11 are provided along opposing longitudinal inner walls of the side wall, and the cool air outlet 10 is an upper end of a cold air outlet kit 12 rising along the inner wall of the side wall. The portion is provided so as to blow cool air in a substantially horizontal direction toward the opposing side wall. The cool air outlet kit 12 having the cool air outlet 10 is formed of a transparent material such as a transparent synthetic resin, and is detachably attached to an outlet of the circulation duct 9.

A cool air suction port 11 is provided at an upper end of a cool air passage 14 formed between a side wall 4 and a suction port fence 13 made of a transparent material such as a transparent synthetic resin and erected in parallel with the inner surface of the side wall. Are provided in an open state.

The cold air suction port 11 is provided so that the suction position thereof is higher than the cold air outlet 10. By setting the cold air inlet 11 for sucking and circulating the cool air in the product display section 2 higher than the cool air outlet 10, the air curtain C of the cool air flows as shown in FIG. Later, a cold pool is formed up to the position L shown in FIG. As a result, the cool air outlet 10 and the cool air outlet kit 12 can be located in the cool air in the product display section 2, and the cool air temperature blown out through the cool air outlet kit 12 and the cool air outlet 10 and their outer surface temperatures Can be set to substantially the same temperature, so that dew condensation does not occur on these outer surfaces.
