Abstract
Disclosed are a circuit board assembly and a rice cooker, where the circuit board assembly includes: a housing, including a circuit board bracket and a fireproof cover fixing and covering the circuit board bracket, where the fireproof cover and the circuit board bracket are enclosed to define a fireproof cavity; and a circuit board, mounted on the circuit board bracket and accommodated in the fireproof cavity. The present disclosure provides a fireproof cover made of a fireproof material on the circuit board. The fireproof cover and the circuit board bracket may be fixed and covered to define a fireproof cavity, and the circuit board may be accommodated in the fireproof cavity. In this way, the circuit board may be isolated from the outside, to prevent the fire from spreading when the circuit board catches fire, to ensure the safety of users' lives and property.
