Convected-air cabinet
View Patent ↗A convected-air cabinet ( 10 ) for storage of food has fans ( 62, 84 ) for directing air from a lower part of the apparatus to an upper part. In particular there is an upper fan ( 84 ) mounted above an apertured partition ( 86 ) so that air entering through an aperture ( 88 ) in this partition ( 86 ) is directed laterally and then downwardly to provide air curtains adjacent food access means ( 20 ) at a front ( 16 ) and rear ( 18 ) of the cabinet.
1. A convected-air food storage cabinet comprising:
a front side provided with food access means,
an opposed rear side provided with food access means,
a base, a roof and spaced side walls interconnecting the front and rear sides,
a plurality of food storage regions within the cabinet,
a laterally extending cover extending from and attached laterally to the front and rear sides and spaced from each side wall,
a first fan mounted adjacent the base and arranged beneath and adjacent to the laterally extending cover, the laterally extending cover including a substantially central aperture to allow for ingress of air to the first fan,
a second fan mounted adjacent the roof, and
a laterally extending partition containing a substantially central aperture mounted below and adjacent to the second fan, the laterally extending partition being spaced from the front and rear sides, wherein air directed around the laterally extending cover by the first fan is conveyed upwardly within the cabinet initially along the side walls and subsequently to the central aperture in the laterally extending partition and is then directed laterally along the roof by the second fan and subsequently downwardly across the front and rear sides to form air curtains extending downwardly across the front and rear sides.
2. A convected-air food storage cabinet according to claim 1 , further comprising an air heater located adjacent the first fan to heat air directed laterally by the first fan.
3. A convected-air food storage cabinet according to claim 1 , wherein the aperture in the laterally extending partition is disposed adjacent the second fan.
4. A convected-air food storage cabinet according to claim 3 , wherein the laterally extending partition has downwardly turned peripheral flanges adjacent the front and rear sides.
5. A convected-air food storage cabinet according to claim 4 , wherein the laterally extending partition includes upwardly turned peripheral flanges adjacent the side walls.
6. A convected-air food storage cabinet according to claim 1 , wherein the cabinet includes a basin arranged to contain water, in use, so as to humidify air in the cabinet.
7. A convected-air food storage cabinet according to claim 1 , wherein the front and rear sides include doors arranged to be opened and closed to permit loading and unloading of food to and from the cabinet.
8. A convected-air food storage cabinet according to claim 1 , wherein the cabinet includes a plurality of substantially horizontally disposed air permeable shelves arranged to support items of food.
