## Abstract

A cooking device has at least one support and a cooking body which is rotatably attached to the support via a rotatable axis, the cooking body has a tub-shaped cooking container and at least one gas burner. The cooking device has at least one supply line for the gas burner, which is connected to the gas burner, which extends through the rotatable axis and which is configured concentrically with the rotatable axis. The cooking device has an outer pipe surrounding the supply line, the supply line having a smaller diameter than the rotatable axis, as a result of which an annular gap is formed radially between the supply line and the wall of the outer pipe.

## Claims

### Claim 1

A cooking device having at least one support and a cooking body which is rotatably attached to the support via a rotatable axis,
the cooking body comprising a tub-shaped cooking container and at least one gas burner,
the cooking device having at least one supply line for the gas burner, which is connected to the gas burner, which extends through the rotatable axis and which is configured concentrically with the rotatable axis,
the cooking device having an outer pipe surrounding the supply line, the supply line having a smaller diameter than the rotatable axis, as a result of which an annular gap is formed radially between the supply line and the wall of the outer pipe.

### Claim 2 (depends on 1)

The cooking device according to claim 1, wherein the at least one supply line is a line for fuel, in particular gas or a gas-air mixture, for air, in particular fresh air or cooling air, or for exhaust gas.

### Claim 3 (depends on 1)

The cooking device according to claim 1, wherein a drive is provided in the support, which is configured such that it can rotate the rotatable axis along with the cooking body.

### Claim 4 (depends on 1)

The cooking device according to claim 1, wherein at least one first supply line and at least one second supply line are provided, in particular wherein the first supply line is configured as an exhaust gas line and the second supply line is configured as a fuel line or air line, in particular as a cooling air line or fresh air line.

### Claim 5 (depends on 4)

The cooking device according to claim 4, wherein at least one third supply line is provided, in particular wherein the third supply line is configured as a cooling air line, and/or in that at least one fourth supply line is provided, in particular wherein the fourth supply line is configured as a fresh air line.

### Claim 6 (depends on 1)

The cooking device according to claim 1, wherein the annular gap is configured as at least one further supply line and/or a further supply line runs in the annular gap.

### Claim 7 (depends on 1)

The cooking device according to claim 1, wherein the rotatable axis forms the outer pipe.

### Claim 8 (depends on 1)

The cooking device according to claim 1, wherein at least one further one of the supply lines has a common wall section with an exhaust gas-carrying supply line, in particular with the supply line which is concentric with the rotatable axis.

### Claim 9 (depends on 1)

The cooking device according to claim 1, wherein the support has a gas connection and/or an exhaust gas outlet, in particular an exhaust gas outlet socket, and/or in that the support has a fan which is provided in the supply line, in particular in the exhaust gas line.

### Claim 10 (depends on 1)

The cooking device according to claim 1, wherein the at least one gas burner is a premixing gas burner or an atmospheric gas burner.

### Claim 11 (depends on 2)

The cooking device according to claim 2, wherein a drive is provided in the support, which is configured such that it can rotate the rotatable axis along with the cooking body.

### Claim 12 (depends on 2)

The cooking device according to claim 2, wherein at least one first supply line and at least one second supply line are provided, in particular wherein the first supply line is configured as an exhaust gas line and the second supply line is configured as a fuel line or air line, in particular as a cooling air line or fresh air line.

### Claim 13 (depends on 12)

The cooking device according to claim 12, wherein at least one third supply line is provided, in particular wherein the third supply line is configured as a cooling air line, and/or in that at least one fourth supply line is provided, in particular wherein the fourth supply line is configured as a fresh air line.

### Claim 14 (depends on 2)

The cooking device according to claim 2, wherein the annular gap is configured as at least one further supply line and/or a further supply line runs in the annular gap.

### Claim 15 (depends on 2)

The cooking device according to claim 2, wherein the rotatable axis forms the outer pipe.

### Claim 16 (depends on 2)

The cooking device according to claim 2, wherein at least one further one of the supply lines has a common wall section with an exhaust gas-carrying supply line, in particular with the supply line which is concentric with the rotatable axis.

### Claim 17 (depends on 2)

The cooking device according to claim 2, wherein the support has a gas connection and/or an exhaust gas outlet, in particular an exhaust gas outlet socket, and/or in that the support has a fan which is provided in the supply line, in particular in the exhaust gas line.

### Claim 18 (depends on 2)

The cooking device according to claim 2, wherein the at least one gas burner is a premixing gas burner or an atmospheric gas burner.

### Claim 19 (depends on 3)

The cooking device according to claim 3, wherein at least one first supply line and at least one second supply line are provided, in particular wherein the first supply line is configured as an exhaust gas line and the second supply line is configured as a fuel line or air line, in particular as a cooling air line or fresh air line.

### Claim 20 (depends on 19)

The cooking device according to claim 19, wherein at least one third supply line is provided, in particular wherein the third supply line is configured as a cooling air line, and/or in that at least one fourth supply line is provided, in particular wherein the fourth supply line is configured as a fresh air line.
