DESCRIPTION
An object of the present invention is to propose improvements to an impingement food oven of the type illustrated in Figures 1 to 3. A description of this type of oven may be found in more detail in Canadian laid-open patent application no. 2,137,995.
Referring to FIGS. 1 to 3, the impingement food oven (9) comprises a baking chamber (11) having a front wall (29), an end wall (31) and opposite sidewalls (33,35). The baking chamber (11) further comprises a top wall (25) and a bottom wall (27). Two opposite openings (22,22') through which a food receiving conveyor (38) passes to move food (not shown) to be baked at a given speed inside the baking chamber (11) may provided in the sidewalls. Advantageously, the oven (9) comprises an access door (36) for easy loading of quick cooked items such as precooked meat.
The oven (9) further comprises an air circulating system to circulate air within the baking chamber (11). More particularly, the air is drawn from the baking chamber (11) through a plurality of air suction chambers (24,26) to heat the air that has been so drawn outside of the baking chamber (11) and reinject the so heated air into the baking chamber (11).
A preferred embodiment of an air circulating system which could be provided with that type of oven is illustrated in FIGS. 2 and 3. In this embodiment, the oven (9) comprises two air suction chambers (24,26), two blowers (44, 44'), a blowing chamber (10), a plurality of blown air distributors (30) and a heating chamber (18). The blowing chamber (10) is adjacent to the end wall (31). The heating chamber (18) is in open communication with the suction chambers (24,26) and operatively connected to the blowing chamber (10). The air drawn by the blowers (44,44') passes into the heating chamber (18) before passing through the blowing chamber (10). The air is thus heated while passing through the heating chamber (18).
The blowers (44,44') are both mounted within the blowing chamber (10). One of the blowers (44) is in communication with ~191786 one suction chamber (26) and the other blower (44') is in communication with the other suction chamber. Preferably, a gas conversion burner (50) is provided to generate heat inside the heating chamber (18).
As illustrated in FIG. 3, the air drawn from the baking chamber (11) through the suction chambers (24,26) passes through the blowing chamber (10) which extends at the back end of the end wall (31). The air drawn and blown by the blowers (44,44') is then reinjected back into the baking chamber (11) via a plurality of blown air distributors (30) which are in open communication with the blowing chamber (10) and the baking chamber (11). Preferably, as illustrated, the blown air distributors (30) extend within the baking chamber (11) on the top and bottom walls (25,27) thereof, from the front wall (29) to the end wall (31). Each of the blown air distributors (30) may be tapered or they may have a uniform rectangular cross section and they are provided with a plurality of evenly spaced outlet openings (37).
Referring to FIG. 4 which is a cross-sectional top view of the baking chamber (11) only, the baking chamber is in open communication with the suction chambers (24,26) via a plurality of apertures (16) which are positioned so as not to face the outlet openings (37) of the blown air distributors (30).
IMPR~LML.. l~
1. Improvement to the blowing chamber A first object of the present invention is to provide an air circulating system that improves significantly the displacements of air flow through the blowing chamber (10) compared to the blowing chambers illustrated and described in prior art.
According to that object, and referring to FIGS. 5, 6 and 7, the present invention proposes a blowing chamber (10) having a more aerodynamic shape to accelerate the displacement of air therethrough. More particularly, the walls (52) of the blowing 21917~6 chamber (10) which act as deflectors for directing the air flow are angulated to smooth the path for air and thereby preventing any turbulence of the air in the blowing chamber (10).
Advantageously, a more aerodynamic blowing chamber (10) according to the present invention has shown an increase of the flow of air entering each of the air distributors (30) of at least four times compared to a prior art blowing chamber. Thus, the energy required for operating an oven provided with an aerodynamic blowing chamber (10) according to the present lo invention is proportionally lowered. Thereby, the operating cost of such an oven is greatly reduced.
2. Improvement to the blown air distributors (also called finger ducts) Another object of the present invention is to propose improved blown air distributors (30) which are easy to clean, to remove or to reinstall in the oven (9).
In prior art, the finger ducts (30) are independent from each other so that they are installed or removed one by one by sliding each one of those in guide rails adapted to receive a corresponding finger duct. Therefore, the cleaning of all the finger ducts takes a lot of time and it is very expensive because each of those finger ducts has to be removed, cleaned and put back in the oven, one after another. Moreover, often, the finger ducts (30) are not put back in their proper place, causing thereby a bad performance of cooking.
There is thus presently a need for an impingement food oven provided with air distributors that are very easy to remove, install and put back in the oven.
In accordance with that object, the impingement food oven (9) is provided with at least one air distributor assembly (60) extending within the baking chamber (11) on the top or bottom wall thereof.
Referring to FIGS. 8 to 10, the blown air distributor assembly (60) comprises a single jet plate (62) which preferably has approximately the same surface area than the 219178~
surface area of the baking chamber (11). A plurality of finger ducts (30) is mounted in parallel on that jet plate (62). As illustrated, each of the finger ducts (30) comprises two elongated opposite sidewalls (64), each having a bottom edge (65) secured to an upper surface (66) of the jet plate (62).
Each finger duct (30) further comprises a top wall (68) slidable in opposite guide rails extending on an inner surface of each sidewall (64). The inside of each finger duct (30) is in open communication with the baking chamber (11) via a plurality of outlet openings (37) provided in the jet plate (62). The baking chamber (11) is also in open communication with the suction chambers via a plurality of apertures (16) also provided in the jet plate (62). As can be appreciated, each series of outlet openings (37) is disposed so as to not face a series of apertures (16).
The air distributor assembly (60) may be slid in the baking chamber (11). Advantageously, an air distributor assembly (60) according to the present invention allows each of the finger ducts (30) to be removed or put back in the oven in only one step. Thus, it is very rapid and easy to clean the finger ducts (30) .
Moreover, it prevents the risk of misplacing the finger ducts (30) as they are put back in the oven.
An object of the present invention is to propose improvements to an impingement food oven of the type illustrated in Figures 1 to 3. A description of this type of oven may be found in more detail in Canadian laid-open patent application no. 2,137,995.
Referring to FIGS. 1 to 3, the impingement food oven (9) comprises a baking chamber (11) having a front wall (29), an end wall (31) and opposite sidewalls (33,35). The baking chamber (11) further comprises a top wall (25) and a bottom wall (27). Two opposite openings (22,22') through which a food receiving conveyor (38) passes to move food (not shown) to be baked at a given speed inside the baking chamber (11) may provided in the sidewalls. Advantageously, the oven (9) comprises an access door (36) for easy loading of quick cooked items such as precooked meat.
The oven (9) further comprises an air circulating system to circulate air within the baking chamber (11). More particularly, the air is drawn from the baking chamber (11) through a plurality of air suction chambers (24,26) to heat the air that has been so drawn outside of the baking chamber (11) and reinject the so heated air into the baking chamber (11).
A preferred embodiment of an air circulating system which could be provided with that type of oven is illustrated in FIGS. 2 and 3. In this embodiment, the oven (9) comprises two air suction chambers (24,26), two blowers (44, 44'), a blowing chamber (10), a plurality of blown air distributors (30) and a heating chamber (18). The blowing chamber (10) is adjacent to the end wall (31). The heating chamber (18) is in open communication with the suction chambers (24,26) and operatively connected to the blowing chamber (10). The air drawn by the blowers (44,44') passes into the heating chamber (18) before passing through the blowing chamber (10). The air is thus heated while passing through the heating chamber (18).
The blowers (44,44') are both mounted within the blowing chamber (10). One of the blowers (44) is in communication with ~191786 one suction chamber (26) and the other blower (44') is in communication with the other suction chamber. Preferably, a gas conversion burner (50) is provided to generate heat inside the heating chamber (18).
As illustrated in FIG. 3, the air drawn from the baking chamber (11) through the suction chambers (24,26) passes through the blowing chamber (10) which extends at the back end of the end wall (31). The air drawn and blown by the blowers (44,44') is then reinjected back into the baking chamber (11) via a plurality of blown air distributors (30) which are in open communication with the blowing chamber (10) and the baking chamber (11). Preferably, as illustrated, the blown air distributors (30) extend within the baking chamber (11) on the top and bottom walls (25,27) thereof, from the front wall (29) to the end wall (31). Each of the blown air distributors (30) may be tapered or they may have a uniform rectangular cross section and they are provided with a plurality of evenly spaced outlet openings (37).
Referring to FIG. 4 which is a cross-sectional top view of the baking chamber (11) only, the baking chamber is in open communication with the suction chambers (24,26) via a plurality of apertures (16) which are positioned so as not to face the outlet openings (37) of the blown air distributors (30).
IMPR~LML.. l~
1. Improvement to the blowing chamber A first object of the present invention is to provide an air circulating system that improves significantly the displacements of air flow through the blowing chamber (10) compared to the blowing chambers illustrated and described in prior art.
According to that object, and referring to FIGS. 5, 6 and 7, the present invention proposes a blowing chamber (10) having a more aerodynamic shape to accelerate the displacement of air therethrough. More particularly, the walls (52) of the blowing 21917~6 chamber (10) which act as deflectors for directing the air flow are angulated to smooth the path for air and thereby preventing any turbulence of the air in the blowing chamber (10).
Advantageously, a more aerodynamic blowing chamber (10) according to the present invention has shown an increase of the flow of air entering each of the air distributors (30) of at least four times compared to a prior art blowing chamber. Thus, the energy required for operating an oven provided with an aerodynamic blowing chamber (10) according to the present lo invention is proportionally lowered. Thereby, the operating cost of such an oven is greatly reduced.
2. Improvement to the blown air distributors (also called finger ducts) Another object of the present invention is to propose improved blown air distributors (30) which are easy to clean, to remove or to reinstall in the oven (9).
In prior art, the finger ducts (30) are independent from each other so that they are installed or removed one by one by sliding each one of those in guide rails adapted to receive a corresponding finger duct. Therefore, the cleaning of all the finger ducts takes a lot of time and it is very expensive because each of those finger ducts has to be removed, cleaned and put back in the oven, one after another. Moreover, often, the finger ducts (30) are not put back in their proper place, causing thereby a bad performance of cooking.
There is thus presently a need for an impingement food oven provided with air distributors that are very easy to remove, install and put back in the oven.
In accordance with that object, the impingement food oven (9) is provided with at least one air distributor assembly (60) extending within the baking chamber (11) on the top or bottom wall thereof.
Referring to FIGS. 8 to 10, the blown air distributor assembly (60) comprises a single jet plate (62) which preferably has approximately the same surface area than the 219178~
surface area of the baking chamber (11). A plurality of finger ducts (30) is mounted in parallel on that jet plate (62). As illustrated, each of the finger ducts (30) comprises two elongated opposite sidewalls (64), each having a bottom edge (65) secured to an upper surface (66) of the jet plate (62).
Each finger duct (30) further comprises a top wall (68) slidable in opposite guide rails extending on an inner surface of each sidewall (64). The inside of each finger duct (30) is in open communication with the baking chamber (11) via a plurality of outlet openings (37) provided in the jet plate (62). The baking chamber (11) is also in open communication with the suction chambers via a plurality of apertures (16) also provided in the jet plate (62). As can be appreciated, each series of outlet openings (37) is disposed so as to not face a series of apertures (16).
The air distributor assembly (60) may be slid in the baking chamber (11). Advantageously, an air distributor assembly (60) according to the present invention allows each of the finger ducts (30) to be removed or put back in the oven in only one step. Thus, it is very rapid and easy to clean the finger ducts (30) .
Moreover, it prevents the risk of misplacing the finger ducts (30) as they are put back in the oven.
3. Controllable deflectors within the air distributors In accordance with another aspect of the present invention, each air distributor (30) comprises means for controlling the air velocity exiting the outlet openings (3~) in a uniform distribution across the jet plate (6~) in order to evenly cook food products in the baking chamber (ll).
Referring to FIGS. 9 to 11, this means for controlling the velocity of air throughout each of the air distributors (30) comprises a controllable deflector (70) positioned within the air distributor (30) near the air inlet (67) of the air distributor (30). Each deflector (70) made of a thin metal sheet comprises a stationary portion including a first 21917~6 backwardly slanted plate ( 72) having opposite side edges each secured to a sidewall ( 64) of the air distributor ( 30) . The stationary portion further comprises a second plate ( 74) extending substantially parallel to the jet plate ( 62) . The second plate ( 74) has also opposite side edges each secured to a sidewall (64) of the air distributor. The deflector (70) further comprises a movable portion including a third plate (76) having an end pivotally connected to a free end of the second plate ( 74) . The third plate ( 76) is movable between a closed position, as shown in FIG. 10, where it is projecting downwardly towards the jet plate ( 62) and an open position, as shown in ~IG. 11, where it is projecting upwardly away from the jet plate ( 62) . An operating handle ( 78) is provided outside the air distributor ( 30) to control the position of this third plate. As can be appreciated, this third plate (76) is movable in order to apportion the incoming air flow within the air distributor ( 30) . In an open position as in FIG. 11, the deflector (70) deflects a portion of the incoming air flow through the outlet openings ( 37) positioned near the inlet of the air distributor ( 30) under the deflector ( 70) . In a closed position as in FIG. 10, the deflector (70) deflects an important portion of the incoming air flow through the front portion of the air distributor (30). As the deflector (70) is in a closed position, the heated high velocity air is exiting all outlet openings ( 37) in a uniform distribution across the jet plate ( 62) in order to evenly cook food products.
Often, certain products such as pizzas require that the bottom surface be more cooked than the upper surface. In order to improve the cooking of such products, the air distributors of the air distributor assembly ( 60) extending on the top wall of the baking chamber (11) are each preferably provided with a second movable deflector (80) for removably blocking the air inlet (67) of the air distributor (30). More particularly, as illustrated in FIGS. 10 and 11, the second deflector (80) comprises a thin metal plate (82) having a width approximately equal to the interior width of the air distributor ( 30) and a bottom side ( 84) pivotally connected to the sidewalls ( 64) of the air distributor (30) such that the second deflector (80) is rotatable about an axis extending parallel to the jet plate (62). The second deflector (80) is rotatable between a closed position where the air inlet (67) of the air distributor (30) is closed, as in FIG. 11, and an open position where the second deflector (80) lets the incoming flow pass through the inlet (67) of the air distributor (30). Therefore, if the upper surface of a product does not require too much cooking compared to its bottom surface, the second deflector (80) just has to be closed.
A second operating handle (86) is provided for controlling the opening of the second deflector (80), as shown in FIG. 8.
Although preferred embodiments of the invention have been described in detail herein and illustrated in the accompanying drawings, it is to be understood that the invention is not limited to these precise embodiments and that various changes and modifications may be effected therein without departing from the scope or spirit of the invention.
Referring to FIGS. 9 to 11, this means for controlling the velocity of air throughout each of the air distributors (30) comprises a controllable deflector (70) positioned within the air distributor (30) near the air inlet (67) of the air distributor (30).

Therefore, if the upper surface of a product does not require too much cooking compared to its bottom surface, the second deflector (80) just has to be closed.
A second operating handle (86) is provided for controlling the opening of the second deflector (80), as shown in FIG. 8.
