Abstract
A wood burning oven comprising a platform having a generally rectangular outline which includes a metal tray with refractory material contained in the tray forming the floor of the oven, a metal enclosure supported on the tray, the enclosure having a semi-cylindrical wall with the axis of the cylinder at right angle to the longitudinal axis of the rectangle, the semi-circular wall forming the cover of the oven, front and rear walls completing the enclosure. An opening is provided in the front wall of the enclosure. and an inlet/outlet tunnel extending outwardly from the front wall is coincident with the opening of the front wall.
An exhaust duct extends upwardly from the top of the inlet/outlet tunnel wall, whereby a wood-burning fire when activated in the oven towards a longitudinal end of the oven causes heat by means of the combustion gases circulating by convection along the contour of the cover of the oven and passing through the opening to exhaust through the exhaust duct.

Description
"PORTABLE OVEN"
The present invention related to a portable oven and more particularly to a wood-burning pizza oven.
Many restaurants that have had pizza-baking facilities adapted for the more traditional wood-fire ovens as opposed to modern day electrical ovens.
Connoisseurs will state that a pizza baked in a wood-burning oven has a better flavor, possibly from the charcoal, and is more evenly baked.
However conventional wood-burning ovens for baking pizzas are stationary facilities, generally build of masonry with refractory bricks forming the interior walls of the oven. There is a need for a port-able wood-burning oven for baking pizzas that can be installed in smaller restaurants or for outdoor events.
It is an aim of the present invention to provide a wood-burning oven which is portable.
It is a further aim of the present invention to provide a wood-burning oven for baking pizzas which can be easily assembled at a designated indoor or out door site.
A construction in accordance with the present invention includes a platform comprising a generally rectangular metal tray with refractory material contained in the tray forming the floor of the oven, a metal enclosure supported on the tray, the metal enclosure having a semi-cylindrical wall forming the cover with front and rear walls completing the enclosure. An opening is provided in the front wall and an inlet/outlet tunnel extends outwardly from the front wall and is coincident with the opening in the front wall. An exhaust duct extends upwardly from the top of the inlet/outlet tunnel wall.
In a more specific embodiment of the present invention the portable oven is a knock-down kit comprising a carriage provided with caster wheels, means on the carriage for mounting a platform consist-ing of a rectangular metal tray, refractory bricks adapted to be set in the tray, and an enclosure to be fitted on the platform, whereby the enclosure includes a metal semi-cylindrical cover with front and rear metal walls; an inlet/outlet tunnel enclosure adapted to be mounted to the front wall surrounding an opening in the front wall, and an exhaust duct adapted to be mounted to the top of the inlet/outlet tunnel wall.
Having thus generally described the nature of the invention, reference will now be made to the accompanying drawings, showing by way of illustration, a preferred embodiment thereof, and in which:
Fig. 1 is a fragmentary perspective view of an embodiment of the present invention;
Fig. 2 is a perspective view taken from a different angle of the embodiment shown in Fig. 1;
Fig. 3 is a perspective view of the knock down element making up the portable oven kit in accor dance with the embodiment of Fig. 1;
Fig. 4 is a perspective view of one of the know-down elements of the kit;
Fig. 5 is a perspective view similar to Fig. 4 but showing another knock-down element assembled to the knock-down element shown in Fig. 4; and Fig. 6 is a perspective view of a partially assembled oven.
The portable pizza oven 10 shown in Figs. 1 and 2 includes a carriage 12 to which is mounted a platform 14. A hooded enclosure 16 sits on the platform 14 while an inlet/outlet tunnel 18 extends forwardly of the enclosure 16. An exhaust duct 20 is mounted to the top of the inlet/outlet tunnel 42.
As shown in Figs. 2, 4 and 5, the carriage 12 includes a light weight metal frame 22 made of steel. The frame 22 includes posts 27 at each corner of a rectangular shelf 26. Caster wheels 24 are mounted at the bottom of each post 27.
The posts 27 are adapted to support and mount the platform 14 which comprises a shallow tray 28. The tray 28 is rectangular and each post 27 coincides with a respective bottom corner of the tray 28. Refractory bricks 30 are placed in the tray 28 to form the floor of the oven.
The oven enclosure 16 includes a cover made up of a semi-cylindrical sheet metal wall 32 as best seen in Figs. 1, 3 and 6. A flat sheet metal rear wall 34 and a sheet metal front wall 36 completes the enclo sure 16. The enclosure 16 is preferably made of steel which has been treated to resist high temperature. The front wall 36 is provided with an opening 31.
An inlet/outlet tunnel 18 includes a wall portion made up of flat side walls 40 and a top semi-cylindrical wall 42. The rear edges of the walls 40 and 42 coincide with the periphery of the opening 31 on the front wall 36. A short upper wall segment 38 extends downwardly from the forward edge of the top wall 42 on the tunnel 18.
The inlet/outlet tunnel 18 is also provided with a platform wall 44 which extends forwardly of the platform 14 forming a hearth. The inlet/outlet tunnel 18 and the platform wall 44 can be mounted to the platform 14 by means of mounting brackets 29 as seen in Fig. 5. A utility bracket 46 may be provided under the platform 44 in order to accommodate utensils such as a pizza paddle. The pizzas are inserted into the oven through the tunnel 18 and opening 31.
The duct 20 is fitted to the top of the wall 42 of the inlet/outlet tunnel 18, and preferably extends to a level to avoid smoke getting into the faces of the oven operator or other persons standing around the oven. The total overall vertical dimension of the pizza oven 10 of the present embodiment, includ-ing the extent of the exhaust duct 20 would be approxi-mately 14 feet. The radius of the semi-cylindrical wall is ------ . The area of opening 31 is ----- .
The shape of the enclosure 16 is considered important to the proper operation of the oven as is the proportional size thereof compared to the opening 31 and the inlet/outlet tunnel 18.
In operation, a small stack of fire wood is inserted within the enclosure 16, either towards the left or the right of the opening 31. The wood is then ignited and allowed to heat up the oven. A pizza to be baked is then inserted into the oven by means of a paddle to sit on the refractory bricks 30 making up the floor of the oven. The top surface of the pizza is heated from the top by convection as the hot combustion gases circulate within the oven following the contour of the semi-cylindrical cover 32. The hot gases are then exhausted through the opening 31 and then through the duct 20. The circulation causes the hot gases to contact the top of the pizza to bake it by convection.
At the same time, the refractory brick floor acts as a heat sink and heats the bottom of the pizza by direct radial contact with the bottom surface of pizza.
A feature of the oven is that it is a knock-down oven and, as shown in the drawings, the various knock-down elements include the carriage 12, the tray 28 and the refractory bricks 30 making up the platform 14. The enclosure 16, the inlet/outlet tunnel 18 and the exhaust duct 20, all of which are separate elements which can be transported to a site to be assembled.
Once the oven has been assembled, it can be moved within a reasonable radius by way of the carriage 12 with caster wheels 24.
