Description

The invention is a hybrid burner that is designed domestic cooking devices which hosts both gas and electricity in the same group and in the middle of the burner there is a plate which can operate with electricity and in the outer region of it there is a flame crown which can operate with gas and also energy consumption is aimed to reduce. This hybrid burner can operate with electricity in the areas without gas and can operate gas in the areas without electricity because of operating both gas and electricity. High speed and low level heat is provided with electricity and it reduces energy consumption. The invention can be adjusted all power levels at the domestic cooking devices. Electric plate can be run at the small power levels, flame crown that operates gas can be run when the high level power is desired and high level power can obtain. In this way, power selection can be made according to heated parts and energy consumption can be achieved by adjusting most appropriate heating. While the electric plate that is positioning at the middle of the hybrid burner provides heat at the lowest level, it goes down the height of the grid with the component that is placed on the plate for heating.
If you need to mention about known art, at the known art the cooking systems that are used homes can be heated either gas or electricity on the same stove. The user at home provides heating for container either putting on the plate with electricity or placing it on the burning head working with gas. Gas powered burning heads are the multiple or single systems that can be mounted on domestic cooking devices and provide the heating for the cooker placed on it. This burning system provides to distribute the flame concentric burning as one, two, three or four step ring shaped. The system adjusts flow of gas through a gas tap and thus burning control can be made of the inner or outer ring. In general, totally three different burning as small, medium and large are provided at three different burners. In addition to these, next to these three burners, some burners that host two or three burner systems inside them have been used. These burners that host two burners generally keep small and large burners at the same time. Generally these burners are separated as 2.1 kW, 2.5kW, 3.6kw, 3.8kW, 4.5kW, and 5kW power systems. However, to obtain this power, every multi-burner should be designed separately and air-gas mixture should be sent to ports of burner right amount.
The burners which have this type of an inner and an outer ring are used in Far East countries for many years. However, this type of burning systems used in Far East can not be provided too much control. Nowadays, the systems that contain one or more internal burning ring have a pre-mixing basin in general. The general objective of this basin is that, the component which is called injector is mounted this basin and provide to mixing the gas that go out from injector rapidly and the air that is located this basin. Another objective of this basin is providing to hold ignition part that has a duty of the burner ignition.
The electric plates connected to the electric supplier can increase electricity gradually when desired and provide to heat for coil with electricity that is located the plate and thus provide to heat the container on the plate.
In the above mentioned systems, when the diameter of burner head and the diameter of electric plate are the same, although electric plates are superior in terms of environmental and emission value, the gas burning stoves are more preferable because of burning with gas produce more power than the electric plates.
Stove and oven manufacturers can provide more suitable costs and more conscious energy consumption on the consumer with hybrid burner that contains these two systems at the same time and this system can be applied on the stove or oven easily. In addition, in this system because of central connection points are the same, oven manufacturers can mount this product more easily.
