Abstract
The present invention provides an open display refrigerator comprising: a refrigerated storage space, air in the refrigerated storage space being separated from air exterior to the open display refrigerator by an air curtain established by a fan which blows air towards an air outlet and which recovers air in the air curtain via an air inlet for recirculation to the air outlet; a wall bounding at least a part of the duct and the refrigerated storage space, the wall comprising one or more voids such that air in the duct can flow into the refrigerated storage space via the one or more voids; a deflector which, when the refrigerator is in use, interrupts at least a portion of the flow of air from the one or more voids and directs the portion of the flow of air towards the top of the refrigerator.
Claims15
An open display refrigerator, comprising:
- a housing defining a refrigerated storage space;
- a fan configured to establish an air curtain that separates the refrigerated storage space from an exterior of the housing;
- an air inlet configured to recover air from the air curtain for recirculation to an air outlet;
- a wall bounding at least a part of the air duct and the refrigerated storage space, the wall including a void such that air in the duct can flow into the refrigerated storage space via the void;
- and
- a deflector configured to interrupt at least a portion of the flow of air from the void direct the portion of the flow of air towards a top of the housing.
A cooling unit, comprising:
- a housing defining an interior space that includes (i) a refrigerated storage space and (ii) an access space;
- a fan configured to establish an air curtain that separates air in the refrigerated storage space is separated from air in the access space;
- an air inlet configured to recover air from the air curtain such that the air can be recirculated to an air outlet;
- a door that separates the interior space from air external to the housing;
- a wall bounding at least a part of the air duct and the refrigerated storage space, the wall including a void such that air in the duct can flow into the refrigerated storage space via the void;
- and
- a deflector configured to interrupt at least a portion of the flow of air from the void and direct the portion of the flow of air towards the top of the housing.
