The hardware design of Instant Pot has matured for many years. Millions of electric pressure cookers of the same design are in use worldwide. However, our design team have been working on improvement to safety and performance for the last 6 months. I’d like to mention two most notable hardware enhancements.
The original power cable connector has a flat surface, see image on right. Liquid could drip from the lid or water collector along the cooker housing wall into the connector, which could become a power short-circuit hazard. Although none of such incident happened, our design team added a shield to redirect water away from the connector. This shield protect the power connector from any spilling water. See the new design in the picture on right.
Better Steam Release
The original steam release has a metal cone inside to seal over the steam release pipe on the lid. Metal on metal doesn’t always create a tight seal. There were reports of steam constantly leaking from the steam release. Although the defect rate is very low, at about 0.6%, our design team believed that they can resolve the problem once for all. The solution is to use a silicone rubber cone in the steam release. The silicone rubber cone creates a tight seal over the steam release pipe. This design was shipped with the last container load of Instant Pot IP-CSG60 and we haven’t had any report of leaky steam release.
