- FIG. 8A is a perspective view illustrating an open/closed state when the guide protrusion 330 is at the second position L2
- FIG. 8B is a perspective view illustrating the lift pin 140 when the guide protrusion 330 is at the second position L2. It is a cross-sectional view for explaining the pin-up position of .
- the safety cover 610 When the guide protrusion 330 is located at the second position L2, the safety cover 610 is located below the safety protrusion 240 and may not serve to fix the safety protrusion 240. That is, even if the safety cover 610 provides elastic force in the +Z-axis direction, since it only contacts the lower part of the safety protrusion 240, the rotary cover 200 can rotate without being fixed. However, even though the user does not operate the control handle 102, the fixation by the safety cover 610 may be released due to a relatively large impact, and a safety accident may occur due to this situation.
- the rotating cover 200 includes a safety area 231, so that even if the safety cover 610 is unfixed due to a defect or impact, The locking structure 300 may maintain a locked state with the inner pot 1000 .
- the safety cover 610 prevents a situation in which the rotating cover 200 rotates unnecessarily, so that it can serve as a primary safety device. Nonetheless, when the rotating cover 200 rotates unnecessarily, the reed switch 620 opens the internal passage of the solenoid valve 160 through an electrical control signal, thereby reducing the vapor pressure of the accommodation space of the inner pot 1000 to atmospheric pressure. Since it can be maintained, the reed switch 620 and the solenoid valve 160 can serve as a secondary safety device. Nevertheless, when the internal passage of the solenoid valve 160 is not opened, the lift pin 140 slides from the first surface portion 141 to the second surface portion 142 and lifts the weight 152. Since the vapor pressure of the accommodation space of the inner pot 1000 can be maintained at the atmospheric pressure level, the lift pin 140 and the first and second surface portions 141 and 142 can serve as a tertiary safety device.
