Abstract

A gas control valve for a hob includes a valve housing, and a valve body accommodated in the valve housing. The valve body is rotatable in a predetermined direction of rotation from a closed position, in which the gas control valve is closed, into an open position, in which the gas control valve is open. The valve body is rotatable in the predetermined direction of rotation beyond the open position into a low-flame position when the valve body is rotated from the open position into the low-flame position for controlling a flow volume of combustion gas flowing through the gas control valve/The valve body is rotatable in opposition to the predetermined direction of rotation from the open position into a booster position, in which the flow volume of combustion gas is greater than the flow volume of combustion gas in the open position.

First claim

The invention claimed is:

1. A gas control valve for a hob, comprising:
a valve housing having only a single gas outlet; and
a tubular valve body accommodated in the valve housing, said valve body having exactly one gas aperture disposed on a peripheral wall of the valve body, wherein the valve body is rotatable in a predetermined direction of rotation from a closed position, in which the gas aperture is covered by the valve housing and the gas control valve is closed, into an open position, in which the gas control valve is open;
wherein the valve body is rotatable in the predetermined direction of rotation beyond the open position into a low-flame position;
wherein the gas control valve is continuously adjustable by rotating the valve body between the open position and the low-flame position to control a flow volume of combustion gas flowing through the gas aperture to the single gas outlet; and
wherein the valve body is rotatable against the predetermined direction of rotation from the open position into a booster position, in which the flow volume of combustion gas flowing through the gas aperture is greater than the flow volume of combustion gas in the open position.

2. The gas control valve of claim 1 , wherein the flow volume of combustion gas is constant in the booster position.

3. The gas control valve of claim 1 , further comprising a timer device configured to rotate the valve body automatically from the booster position into the open position after a predetermined time interval has elapsed.

4. The gas control valve of claim 1 , wherein the valve body is pressable into the valve housing to thereby enable a rotation of the valve body from the open position into the booster position.

5. The gas control valve of claim 1 , further comprising a spring device applying a spring force, with the valve body being pressable into the valve housing in opposition to the spring force of the spring device.

6. The gas control valve of claim 5 , wherein the valve body is configured for accommodation in the spring device.

7. The gas control valve of claim 1 , wherein the valve housing is adapted for attachment to a main gas line of the hob.

8. The gas control valve of claim 1 , wherein the booster position is disposed between the open position and the closed position.

9. The gas control valve of claim 1 , wherein the gas control valve is connectible to only a single burner supply line.

10. A hob, comprising
a gas control valve, said gas control valve comprising a valve housing having only a single gas outlet;
a valve body accommodated in the valve housing;
said valve body having exactly one gas aperture, wherein the valve body is rotatable in a predetermined direction of rotation from a closed position, in which the single gas aperture is covered by the valve housing and the gas control valve is closed, into an open position, in which the gas control valve is open;
wherein the valve body s rotatable in the predetermined direction of rotation beyond the open position into a low-flame position;
wherein a flow volume of combustion gas through the gas aperture to the single gas outlet is continuously adjustable by rotating the valve between the open position and the low-flame position; and
wherein the valve body is rotatable against the predetermined direction of rotation from the open position into a booster position, in which the flow volume of combustion gas flowing through the gas aperture is greater than the flow volume of combustion gas in the open position; and
a thermoelement receptacle attached to the valve housing, the thermoelement receptacle being connected to a thermoelement.

11. The hob of claim 10 , wherein the flow volume of combustion gas is constant in the booster position.

12. The hob of claim 10 , the gas control device includes a timer device having an actuator configured to rotate the valve body automatically from the booster position into the open position after a predetermined time interval has elapsed.

13. The hob of claim 10 , wherein the valve body is pressable into the valve housing to thereby enable a rotation of the valve body from the open position into the booster position.

14. The hob of claim 10 , wherein the gas control device includes a spring device applying a spring force, with the valve body being pressable into the valve housing in opposition to the spring force of the spring device.

15. The hob of claim 10 , wherein the valve housing is adapted for attachment to a main gas line of the hob.

16. The hob of claim 10 , wherein the valve body is tubular.

17. A gas oven, comprising
at least one member selected from the group consisting of:
a gas control valve which includes a valve housing having only a single gas outlet; a valve body accommodated in the valve housing, said valve body having exactly one gas aperture, wherein the valve body is rotatable in a predetermined direction of rotation from a closed position, in which the gas aperture is covered by the valve housing and the gas control valve is closed, into an open position, in which the gas control valve is open, wherein the valve body is rotatable in the predetermined direction of rotation beyond the open position into a low-flame position; wherein a flow volume of combustion gas through the gas aperture to the single gas outlet is continuously adjustable by rotating the valve between the open position and the low-flame position, and a thermoelement receptacle attached to the valve housing, the thermoelement receptacle being connected to a thermoelement;
wherein the valve body is rotatable against the predetermined direction of rotation from the open position into a booster position, in which the flow volume of combustion gas flowing through the gas aperture is greater than the flow volume of combustion gas in the open position; and

a hob comprising said gas control valve.
