Abstract

An oven, suitable for domestic use for cooking food, includes sensors for temperature, humidity, convective heat transfer and radiant temperature, and controls convective, radiative and conductive heat fluxes, as well as the rate of mass transfer of water to/and or from an article, such as food, throughout a cooking process. An air circulation channel has inlets and outlet nozzles, and a variable air speed regulator, the inlets, outlets and air speed being configured to provide a relatively high speed of air impingement on an article in the oven, enabling an article to rest on the base of the oven, and to minimise the loss of heat and humidity conditioned air when the oven door is opened. A radiant temperature and convective heat transfer coefficient sensor has first and second sensor spades, with high and low emissivity coatings, connected to a heat sink through conductors, a plurality of temperature sensors in the sensor spades and spaced along the conductors, and an air temperature sensor, and temperature readings are taken periodically to independently determine radiative temperature and the convective heat transfer coefficient of air.
