### Claim 2 (depends on 1)

The cooker of claim 1, wherein the cooling system comprises:
a second heatsink configured to dissipate heat into an environment; and
a heat transfer module;
wherein a cold side of the heat transfer module is coupled to the first heatsink and a hot side of the heat transfer module is coupled to the second heatsink, and the heat transfer module transfers heat from the first heatsink to the second heatsink.

### Claim 3 (depends on 2)

The cooker of claim 2, wherein the cooling system further comprises a fan configured to enhance heat dissipation into the environment.

### Claim 4 (depends on 2)

The cooker of claim 2, wherein the heat transfer module is a Peltier module.

### Claim 5 (depends on 1)

The cooker of claim 1, wherein the processor is configured to control at least one of: power level, start time, and end time of the respective cooling and heating systems.

### Claim 6 (depends on 1)

The cooker of claim 1,
wherein
the first heatsink comprises a portion mounted to an inner side wall of the outer pot, the inner side wall of the outer pot extending upward from an inner bottom surface of the outer pot, and
the first heatsink includes a contact surface, the contact surface of the first heatsink is in contact with and is shaped to conform with the outer side wall of the inner pot for thermal coupling, the outer side wall of the inner pot extending upward from an outer bottom surface of the inner pot.

### Claim 7 (depends on 6)

The cooker of claim 6, wherein the heating system comprises a heating element installed at the inside bottom of the outer pot, wherein the inner pot sits directly above the heating element when the inner pot nests with the outer pot.

### Claim 8 (depends on 1)

The cooker of claim 1, wherein the heating system comprises a resistive heating element.

### Claim 9 (depends on 1)

The cooker of claim 1, further comprising a user interface configured to receive user input commands.

### Claim 10 (depends on 1)

The cooker of claim 1, further comprising a wireless interface configured to receive user input commands from a wireless device.

### Claim 11 (depends on 1)

The cooker of claim 1, wherein the processor is configured to control the cooling and heating systems to perform multiple cooking functions.

### Claim 12 (depends on 1)

The cooker of claim 1, wherein cooling system and the heating system are fixed to or integrated into the inner pot.

### Claim 13 (depends on 6)

The cooker of claim 6, wherein the contact surface of the first heatsink of the cooling system extends along a circumferential direction of the outer side wall of the inner pot, and
a dimension of the contact surface of the first heatsink along the circumferential direction is greater than a dimension of the contact surface of the first heatsink in a vertical direction.

### Claim 14 (depends on 6)

The cooker of claim 6, wherein the cooling system includes a heat transfer module,
wherein a cold side of the heat transfer module is coupled to the first heatsink,
wherein the heating system comprises a resistive heating element under the outer bottom surface of the inner pot, and
wherein each of the heat transfer module of the cooling system and the first heatsink of the cooling system overlaps with the outer side wall of the inner pot in a side view.

### Claim 15 (depends on 4)

The cooker of claim 4, wherein the first heatsink of the cooling system extends from the Peltier module to the outer side wall of the inner pot past the outer side wall of the outer pot, such that the first heatsink of the cooling system directly supports the inner pot and spaces the inner pot away from the inner side wall of the outer pot.

### Claim 16

A method for heating food comprising:
locating food in a first pot;
