Abstract
Disclosed is an electric pressure cooker. The electric pressure cooker's food container is locked to its lid by using a driving power of a motor. The inner pressure state of the container can be monitored from the outside, and is automatically discharged when it exceeds a predetermined pressure.
Claims28
An electric pressure cooker, comprising:
- a cooker body with a food container;
- a lid for opening/closing said container;
- locking means which locks or releases said lid with said container;
- and
- driving means for driving said locking means.
2 more elements
An electric pressure cooker, comprising:
- a food container;
- a lid for opening/closing said container;
- an auxiliary lid which is mounted to said lid and is able to be slightly raised by the pressure in said container;
- and
- a pressure display means which is raised together with said auxiliary lid, and allows the user to monitor the pressure level in said inner pressure state of said food container from the outside.
2 more elements
An electric pressure cooker, comprising:
- a food container;
- a lid for opening/closing said container;
- a sealing member which is mounted to said lid and contacts said container, thereby preventing the leakage of vapor;
- and
- a safety means which is mounted to said sealing member that discharges vapor when the inner pressure in said food container exceeds a predetermined pressure.
2 more elements
An electric pressure cooker, comprising:
- a container;
- a lid for opening/closing the container;
- an auxiliary lid which is mounted to said lid;
- a sealing member which is mounted to said auxiliary lid contacted with said container, thereby preventing a leakage of vapor during cooking;
- an engaging member which locks a contact portion between said auxiliary lid and said container, and is elevated together with said auxiliary lid;
- a vapor discharge means which discharges vapor so as to maintain a predetermined pressure in the inside of said food containerby said vapor generated when cooking;
- and
- safety means which is provided to said engaging means, prevents said auxiliary lid from elevating when an inner pressure in said food containeris between a first pressure higher than said predetermined pressure and a second pressure, elevates said auxiliary lid when said inner pressure of said food containeris higher than said second pressure, and discharges vapor through a gap between said food containerand said auxiliary lid simultaneously with enlarging an inner volume of said container.
