Oven steam generator systems and methods
First Claim
1. A steam oven for use on-board a transportation vehicle, the oven comprising steam generator system comprising:
- an oven cavity;
an oven heat generating system positioned inside the oven cavity and configured to heat the oven cavity, wherein the oven heat generating system comprises a series of one or more heater elements inside the oven cavity;
a water reservoir in fluid communication with a steam delivery system, wherein the water reservoir comprises a water reservoir tube positioned inside the oven cavity in close proximity to the oven heat generating system and configured to conform to the approximate shape of the series of one or more heater elements, such that heat is transferred to water in the water reservoir tube in order to generate steam in the water reservoir,wherein the steam delivery system comprises at least one open steam outlet at the end of the water reservoir tube or anywhere along the water reservoir tube,such that heat is transferred to water in the water reservoir tube in order to form steam inside the tube, and wherein the steam exits the tube at the at least one open steam outlet of the tube and is delivered directly into the oven cavity.

Abstract
Embodiments of the present invention relate generally to steam ovens, and particularly to steam ovens configured to generate and deliver steam directly to the oven using a water reservoir in close proximity to an existing oven heat generating system. The steam ovens described may be designed so that they inject steam directly into the oven cavity, and in some instances, generate the steam directly in the oven cavity as well. Certain embodiments are designed with a water reservoir in close proximity to an oven heat generating system such that water in the reservoir is heated, turned to steam, and delivered to the oven cavity via a steam delivery system.

11. A method for generating steam in a steam oven on board a transportation vehicle, comprising
(a) providing a steam generator system comprising: -
an oven cavity; an oven heat generating system positioned inside the oven cavity and configured to heat the oven cavity, wherein the oven heat generating system comprises a series of one or more heater elements inside the oven cavity; and a water reservoir in fluid communication with a steam delivery system, wherein the water reservoir comprises a water reservoir tube positioned inside the oven cavity in close proximity to the oven heat generating system and configured to conform to the approximate shape of the series of one or more heater elements, such that heat is transferred to water in the water reservoir in order to generate steam in the water reservoir, wherein the steam delivery system delivers steam from the water reservoir directly into the oven cavity; (b) providing water to the water reservoir; (c) providing heat to the oven heat generating system; (d) allowing the oven heat generating system to deliver heat to the water reservoir either directly or indirectly, causing steam to be generated in the water reservoir; and (e) delivering the steam to the oven cavity via the steam delivery system.
