Inner pot locking device of electric pressure pot

Abstract

The invention discloses an inner pan locking device for an electric pressure cooker, comprising, an inner pan being open at the top and provided with a secured portion at the top, an inner pan for closing the inner pan, an operation handle for locking a inner pan lid or unlocking therefore, a plurality of lock means which according to the action of the handle makes a straight move from the secured portion of the inner pan and the peripheral of the inner pan lid, a motion transformation mechanism for converting the rotation of the handle into a straight movement and transferring it to the locking device. The invention can complete the locking or unlocking action with a very small force, thus makes the convenience to be increased.

Description

technical field [0001] The invention relates to an electric pressure cooker, in particular to an inner pot locking device of the electric pressure cooker. Background technique [0002] Usually, the electric pressure cooker cooks with electricity as heating, and maintains a high-pressure state in the pot, so that the heating temperature exceeds the heating temperature under normal atmospheric pressure, thereby completing cooking quickly, such as figure 1 As shown, it includes: an inner pot 10; a pot body shell 12 for placing the inner pot 10 inside; a pot cover 14 for opening and closing the pot body shell 12; an electric heating device 16 for heating the inner pot 10; a steam exhaust device for adjusting the pressure in the pot constitute. [0003] The electric pressure cooker uses the electric heating device 16 to heat the inner pot 10 for cooking. During the cooking process, the inner pot 10 is closed, and the steam exhaust device remains closed, so that the steam generat...

AI Technical Summary

Problems solved by technology

[0009] However, the locking ring 32 of the inner pot locking device designed in the prior art rotates over the entire area of ​​the inner pot cover 30, thereby opening or closing the inner pot, and when the inner pot cover 30 is heated and deformed, the rotation of the locking ring 32 will be affected. Interference, so it is impossible to flexibly seal or open the inner pot10

[0010] The handle 20, connecting rod 22, and locking ring 32 of the inner pot locking device designed in the prior art are connected to each other, thereby performing the sealing or opening action of the inner pot 10 together, so the user seals or opens the inner pot 10 and operates the handle 20. The force is very large, resulting in the inconvenience of use
