Abstract
An oven includes a food chamber with an access door which houses a water evaporator chamber in fluid communication with the food chamber. By sensing the temperature of the water in the evaporator and the dry bulb temperature within the food chamber and by controlling a dry heat source that heats the air and a wet heat source that heats the water, the cook can control both the final food temperature and the degree of browning of the food.
Claims10
An oven for cooking food, comprising:
- a housing defining a food chamber;
- an access door to said food chamber, said access door defining an evaporator and defining an opening which puts said evaporator in fluid communication with said food chamber when the access door is closed;
- a first heat source, located in said evaporator;
- a first temperature sensor, which senses the temperature in said water evaporator;
- a second heat source, located in said food chamber;
- a second temperature sensor, which senses the temperature in said food chamber;
- first and second user inputs for setting the desired food temperature and the desired degree of browning;
- and
- a controller, which receives signals from said first and second temperature sensors and from said first and second user inputs, and which controls said first and second heat sources to reach the desired food temperature and the desired degree of browning.
6 more elements
An oven, comprising:
- a housing defining a food chamber;
- a door pivotably mounted to said housing and providing access to said food chamber, said door having an outer wall and an inner wall and defining a evaporator, wherein said inner wall defines a fill port and said outer wall defines a drain port for said evaporator;
- a first heat source, located in said evaporator;
- a first temperature sensor, which senses the temperature in said evaporator;
- a second heat source, located in said food chamber;
- a second temperature sensor, which senses the temperature in said food chamber;
- first and second user inputs for setting the desired food temperature and the desired degree of browning;
- a controller, which receives signals from said first and second temperature sensors and from said first and second user inputs, and which controls said first and second heat sources to reach the desired food temperature and the desired degree of browning;
- and
- an air sparger which injects air into said evaporator.
7 more elements
A method for cooking food, comprising the steps of:
- inserting food into an oven chamber which has an access door;
- inserting water into a evaporator defined in said access door, wherein said evaporator is in fluid communication with said oven chamber when said access door is closed;
- closing the access door;
- and
- controlling a first heater in the evaporator and a second heater in the food chamber to control the food temperature and the degree of browning of the food.
