Safety lid for a pressure cooker
A safety lid is provided for an electric pressure cooker. The electric pressure cooker comprises a housing, an outer pot received in the housing, and an inner pot removably disposed within the outer pot. The safety lid includes a lid body for covering the inner pot, an inner rim extending from the lid body for lockably engaging with an upper rim of the outer pot, and an outer rim extending from the lid body and being substantially concentric with the inner rim. The inner rim and the outer rim of the safety lid are spaced apart to define an annular groove for receiving an upper rim of the housing. An electric pressure-cooking appliance equipped with the safety lid is also provided.
1. A lid for an electric pressure cooker, the electric pressure cooker comprising a housing, an outer pot received in the housing, an inner pot removably disposed within the outer pot, the lid comprising:
a lid body for covering the inner pot;
an inner rim extending from the lid body for lockably engaging with an upper rim of the outer pot;
an outer rim extending from the lid body and being substantially concentric with the inner rim; and
wherein the inner rim and the outer rim are spaced apart to define an annular groove for receiving an upper rim of the housing or a portion thereof;
wherein the inner rim is receivable between the outer pot and the housing; and
wherein the outer pot, the inner rim, the housing, and the outer rim define a steam pathway for directing and discharging excess steam outside of the electric pressure cooker along a first downward direction between the outer pot and the inner rim, a second upward direction between the inner rim and the housing, and a third downward direction between the housing and the outer rim.
2. The lid of claim 1 , wherein the outer rim is constructed and arranged to be removably attachable to at least one of the lid body and the inner rim.
3. The lid of claim 1 , wherein the outer rim is configured to partially surround an exterior periphery of the inner rim.
4. The lid of claim 1 , wherein the outer rim has at least one interrupted or non-continuous section.
5. The lid of claim 1 , wherein the outer rim is configured to have varying heights measured from a bottom of the annular groove along a periphery of the outer rim.
6. The lid of claim 1 , wherein the outer rim is at an angle to the inner rim.
7. The lid of claim 1 , wherein the outer rim has a height that is greater than that of the inner rim.
8. A lid assembly for an electric pressure cooker, the electric pressure cooker comprising a housing, an outer pot received in the housing, an inner pot removably disposed within the outer pot, the lid assembly comprising:
a first part comprising a lid body for covering the inner pot and an inner rim extending from the lid body for lockably engaging with an upper rim of the outer pot, the inner rim being integrally formed with the lid body; and
a second part comprising an outer rim extending from the lid body and being substantially concentric with the inner rim, wherein the inner rim and the outer rim are spaced apart to define an annular groove for receiving an upper rim of the housing or a portion thereof, and wherein the outer rim is removably attachable to the first part;
wherein the inner rim is receivable between the outer pot and the housing; and
wherein the outer pot, the inner rim, the housing, and the outer rim define a steam pathway for directing and discharging excess steam outside of the electric pressure cooker along a first downward direction between the outer pot and the inner rim, a second upward direction between the inner rim and the housing, and a third downward direction between the housing and the outer rim.
9. An electric pressure-cooking appliance comprising:
a housing;
an outer pot received in the housing;
an inner pot removably disposed within the outer pot; and
a lid comprising a lid body for covering the inner pot, an inner rim extending from the lid body for lockably engaging with an upper rim of the outer pot, and an outer rim extending from the lid body and being substantially concentric with the inner rim, wherein the inner rim and the outer rim are spaced apart to define an annular groove for receiving an upper rim of the housing or a portion thereof; wherein the inner rim is receivable between the outer pot and the housing; and wherein the outer pot, the inner rim, the housing, and the outer rim define a steam pathway for directing and discharging excess steam outside of the electric pressure cooker along a first downward direction between the outer pot and the inner rim, a second upward direction between the inner rim and the housing, and a third downward direction between the housing and the outer rim.
10. The electric pressure-cooking appliance of claim 9 , wherein the outer rim is constructed and arranged to be removably attachable to at least one of the lid body and the inner rim.
11. The electric pressure-cooking appliance of claim 9 , wherein the outer rim is configured to partially surround an exterior periphery of the inner rim.
12. The electric pressure-cooking appliance of claim 9 , wherein the outer rim has at least one interrupted or non-continuous section.
13. The electric pressure-cooking appliance of claim 9 , wherein the outer rim is configured to have varying heights measured from a bottom of the annular groove along a periphery of the outer rim.
14. The electric pressure-cooking appliance of claim 9 , wherein the outer rim has a height that is greater than that of the inner rim.
15. The electric pressure-cooking appliance of claim 9 , wherein the outer rim is at an angle to the inner rim.
