Abstract

A parameter control system for an oven which may, for example, be a baking oven or a convection oven having the capability of injecting steam into the cooking cavity. The parameter control system precisely controls cooking temperature, cooking time, humidity and air flow in the oven. The parameters can be easily and repeatably set.

Claims

1. A heating system for an oven comprising:

a plurality of oven zone locations in a single oven in which a plurality of heating operations can take place;

a plurality of product selection keys which upon one actuation of a first key selects at least one heating parameter for a given product and which upon another actuation of a key indicates a specific oven zone location for placing the given product prior to heating.

2. A heating system in accordance with claim 1 in which said heating parameter is temperature.

3. A heating system for an oven comprising:

a plurality of oven zone locations in a single oven in which a plurality of heating operations can take place;

a plurality of product selection keys which upon at least one of a plurality of actuations of a first key selects at least one heating parameter for a batch of a given product and which upon another actuation of said first key indicates a specific oven zone location for the batch of the given product.

4. A heating system for an oven comprising:

a plurality of oven zone locations in a single oven in which a plurality of heating conditions can take place;

a plurality of product selection keys which upon one actuation of a first key selects at least one heating parameter for a given product and which upon another actuation of a key indicates a specific oven zone location for the given product to be placed and in which upon one actuation of a second of said plurality of product selection keys selects said at least one heating parameter at the same value for a second given product and which upon another actuation of the second key indicates another specific oven zone location for the second given product to be placed.
