) oven showcase is equipped with a cooler in the back area of the cold air circulation duct, a blower fan in the upper part on the leeward side of the cooler, and both left and right ends of the ceiling air duct formed on the discharge side of the blower fan. A pair of left and right partition plates are provided, the width of which is selected according to the direction of the airflow from the fan, and which set the width of the central opening of the blow-off duct, and a pair of partition plates are provided in front of the central opening to direct the airflow within the duct. A configuration is shown in which a rectifier plate is provided that sends out toward the ceiling air outlet at the tip.

弁の弁開度を得るようにしている。(c) Problems to be solved by the invention Generally, in an oven showcase, the length of the cooler housed in the cold air circulation duct is made shorter than the length of the insulating wall constituting the main body. A space for adjusting the expansion valve is formed between the left and right sides of the container. That is,
The cooler is usually in the form of a plate fin, and an expansion valve that supplies reduced-pressure refrigerant to the cooler is placed in the space on one side of the cooler, so this space can be used for oven show. The valve opening of the expansion valve is adapted to the ambient conditions of the case.

た。By the way, in the above-mentioned conventional technology, the non-uniformity of the air volume distribution caused by the rotation direction of the blower fan, that is, the strength and weakness of the dynamic pressure, can be corrected by using the partition plate, but the cold air whose temperature has decreased after passing through the cooler and the cooler In other words, the air that does not pass through the space (air that is colder than the outside air) mixes with the air before reaching the blower fan, so the cold air flowing through the ceiling air duct is heated immediately after it is exchanged with the cooler. There was a problem in that the temperature was higher than that of the cold air, and it took a long time from the start of the cooling operation until the temperature of the product storage chamber was lowered to a predetermined temperature.
