Description
- The present invention relates to a gas burner system for a gas cooking hob, in particular for a domestic gas cooking hob. Further, the present invention relates to a gas cooking hob, in particular a domestic gas cooking hob, comprising at least one gas burner system.
- In a conventional gas cooking hob the mixture of gas and primary air for the gas burner assembly is generated by a mechanical system, e.g. a Venturi system. Usually, said mechanical system is designed to work in an optimal way within a given range of a gas flow rate. At a given power, the minimum amount of primary air depends on the distance between a cooking pot and flame port of the gas burner assembly, so that the combustion quality is compliant to the standards and the CO values are below the threshold values. Also the burner efficiency depends on the distance between a cooking pot and flame port of the gas burner assembly. The higher said distance, the lower the burner efficiency. The burner efficiency is the ratio between the amount of heat transferred to the cooking pot and the total heat of the burned gas.
- Further, in the gas cooking hob an automatic extinguishing of the flames would be advantageous. Said extinguishing of the flames could be used in an automatic cooking process or for safety reasons.
- It is an object of the present invention to provide a gas burner system for a gas cooking hob, which allows an improved efficiency of said gas burner system.
- The object is achieved by the gas burner system according to claim 1.

- a gas burner assembly including a plurality of flame ports,

- a gas regulator for regulating a gas flow from the gas inlet to the gas burner assembly,
- a control unit for controlling the supply air fan and the gas regulator, and
- at least one thermocouple for detecting flames above the gas burner assembly and for providing a flame signal to the control unit.
- The core of the present invention is the use of the supply air fan controlled by the control unit on the one hand and the thermocouple for detecting flames above the gas burner assembly and for providing a flame signal to the control unit on the other hand. The gas burner system according to the present invention allows an improved efficiency.
- Preferably, the supply air fan is provided for switching off the gas burner assembly by making the flames lift and/or moving the flames aside, so that the thermocouple is not detecting the flames above the gas burner assembly anymore and the appropriate flame signal is sent to the control unit. The supply air fan allows an automatic extinguishing of the flames on the gas burner assembly. After the flame signal is sent to the control unit, said control unit stops the gas flow from the gas inlet to the gas burner assembly. For example, during an automatic cooking process the flames are automatically extinguished after a predetermined time. Further, the flames may be automatically extinguished for safety reasons. For example, if no cooking pot is detected on the pot support, then the flames are automatically extinguished by the air flow. The shutdown of the gas burner assembly by the air flow is realized by low costs, since fans are usually cheaper than gas valves. Moreover, in a premix system a fan is already present and can be used for extinguishing the flames.
- In particular, the gas regulator comprises a gas tap interconnected between the gas inlet and the gas burner assembly, wherein said gas tap is closed by the control unit, if the thermocouple detects no flames above the gas burner assembly.
- For example, the gas burner system is provided for an automatic cooking process, wherein the gas burner assembly is switched off after a predetermined time.
- Further, the gas burner system may comprise at least one pot sensor for detecting the presence of a cooking pot on the pot support, wherein said pot sensor provides the control unit with a pot signal, and wherein the gas burner assembly is switched off, if no cooking pot is detected on the pot support.

Thus, theair flow 24 depends on thegas flow 26. - The
supply air fan 16 increases the amount of primary air fed to thegas burner assembly 12. Said increased amount of primary air allows alower pot support 14 in order to achieve higher burner efficiencies. The burner efficiency is the ration between the amount of heat transferred to the cooking pot and the total heat of the burned gas. Further, thelower pot support 14 is advantageous for the design of the gas cooking hob.

The shutdown of thegas burner assembly 12 by theair flow 24 is realized by low costs, since thesupply air fan 16 is already present and can be used for extinguishing the flames. - The
supply air fan 16 allows the automatic extinguishing of the flames on thegas burner assembly 12. In particular, during an automatic cooking process the flames are automatically extinguished after a predetermined time or for safety reasons. For example, if no cooking pot is detected on thepot support 14, then the flame is automatically extinguished by theair flow 24. -
