The structure can effectively increase the joint area of the temperature sensing piece 42 and the inner pot 12, thereby ensuring that the measured temperature is more accurate. Of course, in other embodiments, the inner pot may not be a spherical pot, and the inner pot may include an arc-shaped bottom wall and a straight wall (as shown in fig. 19), and the abutting surface abuts against the arc-shaped bottom wall, which can also increase the abutting area of the temperature sensing piece 42 and the inner pot 12. In another embodiment, the inner pan may include a horizontal bottom wall and an arc-shaped sidewall, and the engagement of the engaging surface with the arc-shaped sidewall can also increase the engaging area of the temperature sensing piece 42 with the inner pan 12.

Since the first magnetic means 20 corresponds to the middle of the bottom of the inner pot 12, the temperature measuring unit 40 should be attached to a non-central portion of the inner pot 12 to measure the temperature of the inner pot 12.
