Description

[Detailed explanation of the invention] This invention relates to refrigerators used in business, for example, where products are often taken out from the refrigerator, and the purpose is to store products in the refrigerator and take products out from the refrigerator from different directions. To make it easier to take out products and to reduce leakage of cold air when taking out products.

The following is an explanation of the embodiment of the present invention with reference to the drawings: 1
This is a commercial refrigerator whose main body is composed of an insulating wall 2 that defines a refrigerator interior 3, and a large front opening 4 formed on one side of the side wall of the insulating wall that is the front side is openable and closable. A rotatable large insulating door 5 is provided, and the top opening 6 formed in the ceiling wall is divided into two by a partition member 7, with a small insulating door 8 that can be opened and closed on one side, and an insulating frame 9 on the other side. A metal container 10 for storing cooked food and the like is provided through the container. Reference numeral 11 denotes a cold air passage formed between the recess 2a of the heat insulating wall and the partition plate 12, in which a plate fin cooler 13, an axial blower 14, and a dew pan 15 are housed.
The partition plate has an air outlet 16 formed in its upper part for blowing out the cold air heat-exchanged by the cooler 13 along the bottom surface of the container 10 and the small insulation door 8 as shown by the arrow in FIG. A suction port 17 is formed apart from the inner wall. Reference numeral 18 denotes a shelf disposed inside the refrigerator 3, which is located perpendicular to the large heat insulating door 5 and directly below the small heat insulating door 8 and the container 10. Reference numeral 19 denotes a machine room formed directly under the recess 2a of the heat insulating wall, in which a compressor 20, a condenser 21, a blower 22, etc., which constitute a refrigeration cycle together with the cooler are housed, and an air intake port formed on the lower surface. The air sucked in from the compressor 23 is discharged upward from the exhaust port 25 through the exhaust duct 24 formed along the front recess as shown by the arrow in FIG. 2 to radiate heat from the compressor and condenser. Reference numeral 26 denotes a protrusion formed on the upper surface of the ceiling wall of the heat insulating wall 2 near the exhaust port 25. The protrusion 26 prevents dew water, etc. on the upper surface of the ceiling wall from flowing into the machine room 19 from the exhaust port 25. As shown by the chain line in Figure 2, even if a load 27 or the like is placed on the exhaust port 25, the entire exhaust port 25 will not be blocked, and warm air from the machine room 19 will flow through the gap formed between the exhaust port 25 and the load 27. can be discharged.

With this configuration, a large amount of goods can be stored in the upper and lower parts of the shelves 18 in the interior 3 through the front opening 4 by opening the insulated large door 5, and the goods stored in the upper part of the shelves 18 can be removed through the top opening 6 by opening the insulated small door 8. That is, since the shelves 18 are perpendicular to the insulated large door 5 and located directly below the insulated small door 8 and the container 10, not only is it very easy to store a large amount of goods through the front opening 4 and to remove (small amounts of) goods through the top opening 6, but it also greatly reduces the number of times the insulated large door 5 is opened and closed, facilitating the work of operators in the kitchen. Moreover, when there is no more goods directly below the insulated small door 8, it is possible to remove the goods remaining on the shelves 18 simply by replacing the insulated small door 8 with the container 10. Furthermore, the container 10 not only serves as a lid for closing a part of the top opening 6, but is itself cooled by the cold air in the interior 3, so it can be used to keep cooked foods cool, diversifying the uses of the refrigerator 1. Furthermore, the cold air that has been heat exchanged in the cooler 13 is blown out along the vicinity of the bottom surface of the container 10 and the heat-insulating small door 8, and flows parallel to the top opening 6.
This promotes cooling of the container 10 and at the same time, the heat-insulating small door 8
When the upper opening 6 is opened, the leakage of cold air from the upper opening 6 is reduced.

As mentioned above, this proposal consists of a large insulating door that can be opened and closed in a large front opening formed on one side of the insulating wall that defines the interior of the refrigerator and in which the cooler and blower are installed, and a top opening formed in the top wall. A small insulated door that can be opened and closed and a removable metal container are respectively provided to close each opening, and a shelf is provided inside the refrigerator that is perpendicular to the large insulated door and located directly below the small insulated door and the container. The feature is that the cold air that has been heat-exchanged by the cooler is blown out along the bottom of the container and the small insulating door, so that a large amount of products stored in the refrigerator can be easily removed from the top opening through the front opening. Not only can it be taken out, but also
It is possible to reduce the leakage of cold air from the top opening when the small insulated door is opened, and the number of times the large insulated door is opened and closed can be significantly reduced. Cooked food can be cooled in the container, and the connection between the small insulated door and the container can be reduced. Products on the shelves can be taken out quickly by mutual replacement.
