あった。In the cold air circulation type open showcase according to the prior art described above, unsold products when the store is opened during the day are transported to a place commonly called a backyard when the store is closed at night, and the refrigerator is opened. The showcase is stopped and the showcase is stopped, and the product is returned to the showcase the next morning, or the cooling operation of the showcase is continued after the store is closed at night, and the lighting is turned off.
F, the opening 2a of the showcase is covered with a night cover, and unsold products are cooled and stored in the showcase as they are. However, the method of storing unsold products in the backyard refrigerator at night is extremely labor-intensive, such as transporting the products to the backyard refrigerator after the store closes at night and displaying them again in the showcase before opening the next morning. There was a problem that occurred. Further, in the method of storing unsold products in a showcase, power is wasted because the showcase must be operated under the same conditions as in the daytime even if only a small number of products are cooled and stored. There was a problem.

されることとなる。According to the present invention, since the above-described structure is employed, the lamp is turned on during the daytime and one of the coolers is operated together with the other cooler. The open showcase operates with the same cooling capacity as before, and the circulating air circulates in the ventilation passage and opens from the outlet. A cool air curtain is formed at the outlet to cool the product in the storage space. However, during the night, unsold products are accumulated in a limited portion of the storage space such as on a deck plate of the same open show case, and the lighting is turned off, which turns off the auxiliary contact of the relay. Since the solenoid valve is closed, the supply of the refrigerant to one of the coolers is cut off and the only one of the coolers is operated, and the cover body is pulled out to close the ventilation path and open the side opening. By blowing out circulating air from this side opening, only a limited partial deck of the storage space where the unsold goods are accumulated is cooled. As a result, unsold products are efficiently cooled and stored.

This turns on the auxiliary contact 21a of the relay 21. Since the electromagnetic valve 23 is opened by turning on the auxiliary contact 21a, the refrigerant flows to the one cooler 4a together with the other cooler 4b, and both the coolers 4a and 4b contribute to the cooling. On the other hand, the cover body 15 is wound, and the closing plate 17 is thereby held by the holding metal fittings 25 to close the side opening 2b, and the through hole 15 provided in the cover body 15 is provided.
a, a circulation passage for the circulating air is ensured, so that the open-show case operates with the conventional cooling capacity, and the circulating air circulates in the ventilation passage 3 and blows out from the outlet 6 to the opening 2 a to cool the cool air curtain 8. The product 10 in the storage space 11 is formed and stored by cooling. By the way, during the night, the unsold products 10 are accumulated on the deck plate 13 of the same open show case, and the illumination lamp 18 is turned off by turning off the switch 19, whereby the auxiliary contact 21 a of the relay 21 is turned off.
I do. When the auxiliary contact 21a is turned off, the electromagnetic valve 2
Since 3 is closed, one cooler 4a does not contribute to cooling, and only the other cooler 4b is operated. On the other hand, the cover body 15 is pulled out against the pulling force of the spring body 16a to close the ventilation passage 3 and open the side opening 2b, so that the circulating air is supplied to the other cooler 4b as shown by the dotted arrow.
After passing through the ventilation passage 3, it passes through the side opening 2 b from the middle of the ventilation passage 3, flows around the deck plate 13, and then returns to the normal route which is sucked from the suction port 7 and returns to the ventilation passage 3.
The unsold product 10 placed on 3 is cooled.

るという効果を奏する。According to the present invention, the cooling capacity of the cooler can be varied. The inner box is provided with a side opening at a position lower than the lowermost shelf of the wall. By having a cover that is drawn out from the opening to the storage space and limits the circulation range of the circulating air to a level lower than the lowermost shelf, the cooler operates at normal strong cooling capacity during daytime. In addition, the cover body is wound and a blocking plate that does not accompany it covers the side opening and the through hole provided in the cover body secures the circulation air passage, so that the open showcase has the same cooling capacity as before The circulating air circulates in the ventilation path and blows out from the outlet to the opening to form a cool air curtain to cool the goods in the storage space. However, at night, the unsold products are accumulated in a limited portion of the same open showcase, for example, on a deck plate, which is lower than the lowest shelf in the storage space. On the other hand, the cover body is pulled out to close the ventilation path, and the side opening is opened to allow the circulating air to blow out from the side opening, thereby limiting the circulating range of the circulating air to a position lower than the lowermost shelf. The cooler is operated with a weak cooling capacity corresponding to the limited circulation area of the circulating air, but the circulation air flows only through a limited part of the storage space, so that unsold goods are cooled efficiently. It will be. As a result, when the unsold products are cooled and stored, the products need only be accumulated on, for example, a deck plate in the same open showcase, so that no labor is required, and the cooler can be operated with a weak cooling capacity. This has the effect of reducing power consumption.
