Abstract
A pressure cooking appliance with a bowl and lid therefor, a temperature sensor, a pressure regulating valve, and a steam outlet in communication with the valve. The temperature sensor is disposed in the vicinity of the valve to sense an increase in temperature from steam exiting the outlet for triggering a timer that signals the beginning of and counts down the cooking time.
Claims13
An appliance for cooking food under pressure, the appliance comprising:
- a bowl and a lid (2) designed to be mounted on the bowl to form a leaktight cooking enclosure;
- a temperature sensor (10);
- and
- a pressure-regulating valve (3) that is sensitive to the pressure prevailing inside the cooking enclosure and that is mounted to move between two stable abutment positions, namely a first position in which it shuts off communication from the enclosure to the outside so long as the internal pressure is lower than a predetermined pressure P0, and a second position in which it puts the inside of the enclosure into communication with the outside via a steam outlet (7) once the internal pressure reaches substantially the predetermined pressure P0;
- wherein the temperature sensor (10) is disposed in the vicinity of the outlet (7) so as to make it possible to sense the increase in temperature resulting from the steam passing through the steam outlet (7), and is connected functionally to a timer (11) so as to trigger it once the increase in temperature is sensed for beginning a countdown of the cooking time.

A method of monitoring the cooking cycle of a pressure-cooking appliance, the method comprising:
- sensing the temperature of a jet of steam discharged by a pressure-regulating valve of a pressure-cooking appliance;
- and using the temperature to automatically trigger a timer mounted on the pressure-cooking appliance for beginning a countdown of the cooking time;
- removably mounting the timer on the appliance;
- dissociating the timer from the appliance;
- and monitoring the progress of the cooking cycle remotely from the appliance by consulting the timer.
