Abstract

An apparatus for heating food includes a treating chamber, a multilevel shelving in the treating chamber for supporting the food to be heated; a plurality of blowers arranged in the treating chamber; and heating elements associated with the blowers for generating hot air currents. All the blowers are arranged in a vertically spaced, superposed relationship at one side of the treating chamber and an arrangement is provided for directing the air currents generated by each blower towards another, opposite side of the treating chamber.

Claims

1. In an apparatus for heating food including a treating chamber;

a plurality of horizontally oriented, vertically spaced, superposed shelves dividing the treating chamber into compartments and serving for the support of the food to be heated;

a plurality of blowers arranged in the treating chamber; and

separate heating elements associated with each of the blowers for generating hot air currents;

the improvement wherein all said blowers are arranged in a vertically spaced, superposed relationship at one side of said treating chamber;

each said compartment having a separate one of said blowers in alignment therewith;

the improvement further comprising

(a) means defining vertically oriented lateral shafts in said one side of said treating chamber;

(b) a detachable hood arranged at each blower and having a central suction opening aligned with the respective blower and lateral outlet openings;

each compartment being in communication with said lateral shafts through the central suction opening and the lateral outlet openings of the respective hood for directing the air currents generated by each blower towards another, opposite side of said treating chamber;

(c) means for driving said blowers independently from one another and with different rpm'"'"'s;

(d) a bottom zone forming part of said treating chamber and communicating with said lateral shafts;

(e) a basin provided in said bottom zone of said treating chamber;

(f) means for filling said basin with water;

(g) means for draining said basin;

(h) an electric heater arranged in said basin for heating the water contained therein;

(i) a top side forming part of said treating chamber;

(j) means defining an opening in said top side; and

(k) a movable throttle flap disposed in said opening for controlling the cross-sectional flow passage area thereof.

2. An apparatus as defined in claim 1, wherein each hood further has a web for separating adjoining blowers from one another.
