Abstract
An oven comprising a controller that operates the oven in a food cooking mode and in energy saving mode in which energy consumption of a heater and one or more fans is reduced. In the food cooking mode the controller maintains heated air flow at a first set temperature. In the energy saving mode the controller maintains the heated air flow at a second set temperature, which is less than the first set temperature, thereby reducing energy consumed by the heater. In the energy mode, controller also operates the fan that circulates the heater air and a cooling fan at reduced speeds, thereby reducing energy consumption of both fans.
Claims7
An oven for cooking food comprising:
- an oven chamber,
- a heater and a fan disposed to provide a heated airflow to said oven chamber;
- a temperature sensor disposed to provide a temperature signal indicative of a temperature of said heated airflow;
- and
- a controller that uses said temperature signal to control operation of one or both of said fan and said heater to maintain said temperature of said heated airflow at a first set temperature during a cooking mode and at a second set temperature, which is less than said first set temperature, during an energy saving mode of non-cooking activity of said oven, thereby reducing energy consumed by said heater, wherein said controller comprises a computer that comprises a processor, a memory and an energy saving program, wherein said processor executes at least a first instruction of said energy saving program to maintain said temperature of said heated airflow at said second set temperature and to reduce a speed of said fan, thereby reducing energy consumption by said fan, and wherein said processor executes at least additional instruction of said energy saving program to turn said oven off at or after an expiration of a predetermined time of being in said energy saving mode.
