초록 ▼

A commercial oven, such as a combination oven providing steam and convection heating, may provide for motorized dampers allowing the oven to move automatically between a closed-state high humidity operating mode and an open-state low humidity operating mode according to user input reflecting a desired cooking process. The dampers operate with a conventional steam trap and may provide integrated bypass valves preventing over or under pressure of the cooking volume.

대표청구항 ▼

1. A food cooking oven comprising: an insulated housing including a door closing to define an interior cooking volume in a substantially sealed first state and opening to provide access to the cooking volume in a substantially unsealed second state;a heater communicating with the cooking volume to heat the cooking volume;a steam generator generating steam from a source of introduced water, being electronically actuable to receive a signal controlling a generation of steam;a first damper positioned between the interior cooking volume and exterior atmosphere, and in the substantially sealed first state being electronically actuable to receive a signal controlling an opening of the damper to allow water vapor flow between the interior cooking volume and exterior atmosphere and providing a pressure-activated bypass allowing flow of water vapor between the interior cooking volume and the exterior atmosphere when a predetermined pressure difference between the cooking volume and the exterior atmosphere is reached; andan electronic computer executing a program stored in memory to vary the signal to the damper according to user-entered data and to vary the signal to the steam generator according to user-entered data. 2. The oven of claim 1 wherein the user-entered data indicates a type of food. 3. The oven of claim 1 further including a user interface receiving the user-entered data and wherein the electronic computer provides a data structure mapping a type of food to control data defining control of the damper suitable for cooking the type of food. 4. The oven of claim 1 wherein the user-entered data indicates a desired humidity. 5. The oven of claim 4 wherein the user-entered data is converted to control data of a duty cycle defining a proportion between a time when the signal controls the damper to open and a time when the signal does not control the damper to open. 6. The oven of claim 1 wherein the predetermined pressure difference is a pressure difference of less than one atmosphere. 7. The oven of claim 6 wherein the damper includes a flapper valve biased to a closed position by a biasing element and includes an electronically actuable linger controlled by the signal, where the flapper valve biasing may be overcome by a movement of the finger against the flapper valve or by a gas pressure difference across the flapper value. 8. The oven of claim 7 wherein the biasing element is selected from the group consisting of a weight and a spring. 9. The oven of claim 1 wherein the damper provides a first and second intake port and wherein the signal received by the damper operates, to alternately control the damper to allow water vapor flow preferentially between the first intake port and the exterior atmosphere and to control the damper to allow water vapor to flow preferentially between the second intake port and the exterior atmosphere, wherein the first intake port communicates with the interior cooking volume directly and the second intake port communicates with the interior cooking volume through a steam trap. 10. The oven of claim 9 wherein the steam trap is a container holding water through which the water vapor must flow in passing from the interior cooking volume to the exterior atmosphere. 11. The oven of claim 9 wherein the damper includes a flapper valve biased to a first position by a biasing element blocking water vapor flow through the first intake port and includes an electronically actuable finger controlled by the signal, where the flapper valve biasing may be overcome by a movement of the finger against the flapper valve or by a gas pressure difference across the flapper value to allow flow through the second intake port regardless of the signal. 12. The oven of claim 11 wherein the biasing element is selected from the group consisting of a weight and a spring. 13. The oven of claim 1 wherein the oven includes a motorized fan generating at least two regions of relative high and low pressure within the interior cooking volume and wherein the first damper has a port receiving water vapor from the region of relative high pressure expelling it to the exterior atmosphere; and further including a second damper positioned between the interior cooking volume and exterior atmosphere, being electronically actuable to receive a second signal controlling an opening of the second damper to allow water vapor flow between the interior cooking volume and exterior atmosphere, the second damper having a port at the region of relative low pressure for drawing air from the exterior atmosphere into the interior cooking volume; andwherein the electronic computer provides the second signal to the second damper. 14. The oven of claim 13 wherein the second damper includes a pressure-activated bypass allowing flow of water vapor between the cooking volume and the exterior atmosphere regardless of the signal when a predetermined pressure difference is achieved. 15. The oven of claim 14 wherein the predetermined, pressure difference is a pressure difference of less than one atmosphere. 16. The oven of claim 15 wherein the second damper provides a flapper valve biased to a closed position by a biasing element and includes an electronically actuable finger, where the flapper valve biasing may be overcome by movement of the finger against the flapper valve or by a pressure difference. 17. The oven of claim 13 wherein the first signal and the second signal operate to simultaneously open and close the first damper and the second damper. 18. The oven of claim 1 further including a convection fan for circulating heated air within the interior volume.
