DETAILED DESCRIPTION OF THE INVENTION

A refrigerated display cabinet (10), where the food items such as pizza, pastry etc. is displayed, has a structure which refrigerates the entire structure with a single refrigerator with a refrigerator system (140), comprising a display section (11 ) in a most general state, a material storage (13), a gastronom basket (12) and a refrigerator section (14).

The refrigerator system (140) provides refrigeration of the refrigeration section (14), the display section (11), the gastronom basket (12) and the material storage (13), which are introduced separately inside the refrigerated display cabinet (10), with and integrated air circulation, and comprises a display outlet gap (141 ), a fan box (142), refrigerator (143), a storage outlet gap (144) and an air transmission gaps (145).

The fan box (142) is the section that allows the air to be sucked and sent to the cooler (143) to be cooled, comprising a group of fans. The fan box (142) is located under the display section (11 ).

The display output gap (141 ) is a grated section that allows air suction for fans located in the fan box (142) in the display section (11).

Refrigerator (143) is a heat exchanger that allows the air absorbed through the fans in the fan box (142) to be cooled. The refrigerator (143) is an evaporator and is located in the refrigerator section (14) in the fan box (142) towards the +y direction. The storage outlet gap (144) is a channel that allows the storage containers (121 ) located in the gastronom basket (12) and the heated air circulating in the material storage (13) to reach the fan box (142) again. The storage outlet gap (144) is a channel that opens to the fan box (142) along the +x direction at the bottom of the material storage (13).

Air transmission gaps (145) are the channels that allow the passage of the cold air leaving the refrigerator (143) in the refrigerator section (14) to be distributed to the display section (11 ), the gastronom basket (12), the material storage (13). The cold air leaving the refrigerator (143) through air transmission gaps (145) are provided to circulate inside the refrigerated display cabinet (10) with a single air circulation and cooling cycle.

The display section (11 ) is the section where the food items are displayed to the customers and is located at the front of the refrigerated display cabinet (10). In the display section (11 ), foods are uniformly refrigerated from the bottom and top. In the display section (11 ), shelves (100) where the food items are stored in the -z direction, air transmission gaps (145) under the shelves (100) which provide cooling from the bottom, air dispenser (112) which provides cooling from above, outlet gap (141) through which the air heated inside the display section (11 ) is evacuated. The air dispenser (112) has a honeycomb shaped structure that looks at the display section (11) from the top with a specific angle positioned along the +y direction in the display section (11). A kind of a cold air curtain that prevent introduction of hot air is created over the display section (11 ) by means of the air dispenser (112). The display output gap (141) is the channel that allows the heated air circulating in the display section (12) to reach back into the fan box (142).

The material storage (13) is the refrigerated section where the materials for pizza, pastry etc. are stored. The material storage (13) is located along the -y direction of the gastronom basket (12), and along the -x direction of the refrigerator section (14). The transition of cold air from the gastronom basket (12) to the material storage (13) occurs through the air transmission gaps (145).

Gastronom basket (12) is a structure consisting of gaps within the area surrounded by stainless profiles extending along the -z axis and positioned in the -x direction of the refrigerator section (14) in the +y direction of the material storage (13). Storage containers (121) are placed onto the gastronom basket (12). Storage containers (121 ) are stainless steel containers known as gastronom tubs in the sector, into which materials such as pizza, pastry etc. are placed and whose top and bottom sides are exposed to cold air. The refrigerator section (14) is located between the display section (11) and the material storage (13) and contains the refrigerator system (140) which allows the cooling of the refrigerated display cabinet (10) in its entirety.

The working principle of refrigerated display cabinet (10) is as follows: The air sucked by the fans in the fan box (142) through the display outlet gap (141) and the storage outlet gap (144) is transmitted to the refrigerator (143). The air entering the refrigerator (143) cools the air here by removing the heat of the air absorbed by the heat transfer. The cooled air is separated into 2 directions indicated by the letters “A” and “B” at the outlet of the refrigerator (140). (Figure 3) The cold air following the path "A" cools the display section (11 ) from above by means of the air dispenser (112) while at the same time, cooling the food it contacts by flowing under the shelves (111) located at the display section (11) by means of the air transmission gaps (145). The cold air following the path "B" provides cooling by coming into contact with the storage containers (121) by entering the gastronom basket (12) through the air transmission gaps (145). The air passing to the other gastronom basket (12) via air transmission gaps (145) between gastronom baskets (12) proved cooling by coming into contact with storage containers (121). The cold air following the path "B" is transmitted to the material storage (13) through air transmission channels (145) located under the gastronom basket (12) and refrigerate the food items there. The cold air following the the path "B" passes through the storage outlet gap (144) and returns back to the fan box (142). The cycle repeats.
