- wherein the grill pan assembly includes:
- an insulating structure having a convertible compartment channel and a refrigerator compartment channel, the convertible compartment channel at a first side of the insulating structure to supply cold air to the convertible compartment, and the refrigerator compartment channel at a second side of the insulating structure to supply cold air to the refrigerator compartment;
- a convertible compartment fan at the convertible compartment channel, and the convertible compartment fan to provide cold air from the evaporator to the convertible compartment channel;
- and
- a refrigerator compartment fan at the refrigerator compartment channel, and the refrigerator compartment fan to provide cold air from the evaporator to the refrigerator compartment channel,
- wherein the insulating structure includes at least one air guide opening from the convertible compartment channel to the refrigerator compartment channel, the at least one air guide opening to allow some air to flow into the refrigerator compartment channel when the convertible compartment fan is to operate, and to block some air from flowing backward from the refrigerator compartment to a space of the evaporator,
- wherein the at least one air guide opening includes:
- a negative pressure compensation hole to reduce negative pressure when the refrigerator compartment fan is to rotate;
