6. The cooking appliance according to claim 5, wherein the control device is further configured to control the heating device not to heat and the temperature adjusting device to heat when the detecting device detects that the temperature/pressure in the inner pot reaches a third threshold value while the inner pot is in the pressure maintaining state and the preset time is not reached.
7. The cooking appliance according to claim 5, wherein the control device is further configured to continue to control the heating device and the temperature adjusting device to heat when the detecting device detects that the temperature/pressure in the inner pot does not reach the third threshold value while the cooking appliance is in the pressure maintaining state and the preset time is not reached.
8. The cooking appliance according to claim 5, wherein the control device is further configured to control the heating device to stop heating, and control the temperature adjustment device to cool, and then control the cooking appliance to switch to the heat preservation state when the detection device detects that the temperature/pressure in the inner pan reaches the second threshold.
9. The cooking appliance of claim 5, wherein the temperature conditioning device comprises a semiconductor chilling plate and a heat sink; the first side of the semiconductor refrigeration sheet is matched with the pot cover or the side wall in a heat transfer mode; the second side of the semiconductor refrigeration fin is matched with the heat radiating fin in a heat transfer mode; wherein,
the semiconductor refrigerating sheet is connected with a power supply; when the current loaded on the semiconductor refrigerating sheet is in a first direction, a heating end is formed on the first side of the semiconductor refrigerating sheet so as to heat the pot cover/side wall;
when the current loaded on the semiconductor refrigerating sheet is in a second direction, the first side of the semiconductor refrigerating sheet forms a refrigerating end so as to cool the pot cover/side wall.
10. The cooking appliance of claim 9, wherein the temperature conditioning device further comprises a heat dissipating fan disposed above the heat sink.
