Refrigerating device with cooling of circulating air
View Patent ↗A refrigerating device is subdivided by a first partition into a storage zone and an air distribution zone. An air supply inlet and an air outlet open into the air distribution zone, and a plurality of holes are formed in the partition for letting air through from the air distribution zone into the storage zone and vice versa.
1. A refrigerating device comprising:
a.) a first cooling region;
b.) at least one air supply aperture;
c.) an air discharge aperture, the first cooling region being supplied with cold air delivered thereto in a forced air circulation manner under the motive force of a fan with the cold air being supplied by way of the at least one air supply aperture and air exiting the first cooling region exiting via the air discharge aperture; and
d.) a first partition that subdivides the first cooling region into a storage zone in which items to be cooled are stored and an air distribution zone, the air supply aperture and the air discharge aperture being communicated with the air distribution zone and the first partition having a plurality of holes for the passage of air therethrough such that air travels from the air distribution zone to the storage zone via the plurality of holes and air travels from the storage zone to the air distribution zone via the plurality of holes; and
wherein the air distribution zone is subdivided by a second partition into an upstream area and a downstream area, the upstream area of the air distribution zone being communicated with the air supply aperture and with the storage zone such that cold air is supplied into the upstream area and all of the supplied cold air exits the upstream area into the storage zone, and the downstream area of the air distribution zone being communicated with the air discharge aperture and with the storage zone such that air exits the storage zone into the downstream area and thereafter exits the downstream area via the air discharge aperture; and
a second cooling region separate from the first cooling region, and an intermediate wall, the second partition being molded as a single part on the first partition and having a free end, the free end of the second partition adjoining the intermediate wall, the intermediate wall separating the first cooling region from the second cooling region in a thermally insulating manner.
2. The refrigerating device as claimed in claim 1 , wherein the second partition serves as a deflection element, deflecting the cooling air flowing into the first cooling region toward the first partition.
