The subject of the invention is a heating cooker hob with gas burners designed for using it as kitchen equipment. The invention relates also to gas burners. The heating hob is the base of a detached gas cooker or it may function as a part of kitchen furniture. Gas cookers as well as heating cooker hobs are popular kitchen utensils.
They all, the detached ones as well as those arranged in the kitchen cupboards line, have open burners, which heat the pots by means of open fire. Hot fumes go round the bottom and the edges of pots going further to the air of the room. A gas burner as a part of a kitchen heating cooker hob is also known and used. It is in the shape of a metal can to which at the top a plate with holes is fixed and at the bottom part of it there is a diffusion pipe, an injector and a gas nozzle. The mixture of gas and air, produced in the injector passes through he diffusion pipe and hits the inside of the burner and goes out unevenly through the holes in the burner plate and is being burnt on its outside surface. Another disadvantage of the known burner is the fact that the diffusion pipe and the injector have to match the size, the shape of the casing, the capacity of the burner as well as the kind of gas used.
A disadvantage of the heating cooker hobs with the known burners is a troublesome way of lighting the burners. This requires first opening of a valve, lighting a match or using a Ughter or starting an ignition spark lighter, then the flame is set with a knob. While setting the valve knob on small capacity there are some difficulties with lighting. When changing the valve knob the capacity of a gas burner also changes and consequently combustion parameters also change and this increases the amount of carbon dioxide emitted to the air of the room. While cooking, when it happens that the hquid comes out of the pot there is a danger of pouring the content of the pot onto the burner and the flame might be put off and consequently the flow of gas might occur.
The main idea of the invention is the heating cooker hob having a support bracket, gas burners, ceramic plate and a special ventilation system ensuring the effective cooling of the elements of the heating cooker hob as well as cooling the fumes coming from the burners.
The heating cooker hob, according to the invention, has a support bracket to which gas burners with fumes tunnels are fixed. They are fixed in such a way that around gas burners there some gaps and the fumes tunnels are placed over the support bracket in some distance making the air passage possible. The air coming out from the gaps round the burners comes out from beneath the support bracket and goes to the outlets in the back part of the heating cooker hob. The support bracket has also additional holes done around the gas burners and on the edges of it. They help to cool the support bracket, the fumes tunnels as well as the control-indicating panel, which is in the front part of the heating cooker hob. In the back of the support bracket there are holes through which the air passes. It cools the fumes coming out of fumes tunnels. Under the support bracket there is a set of electric valves and an electric steering module. They are fixed within a distance from the support bracket to enable the free passage of air, which cools these elements. The vertical, outside walls of the fumes tunnels are furnished with thermal insulation. The same kind of insulation has the control-indicating panel. On the top of the invented heating cooker hob there is a ceramic plate cover, on which there are heating areas marked. They are placed over the gas burners. There is also a control indicating area over the control-indicating panel. Between the ceramic plate and the upper edges of the fumes tunnels there is a thermal insulation having also a sealing function.
The important feature of the invention is a gas burner, which is also a basic element of the heating cooker hob. Its casing is in the shape of a metal can with a ceramic heating element. It has an inner, solid, horizontal, metal plate, beneath which there is a solid diffuser. At the beginning of the diffuser there is an injector and a gas nozzle. Inside the solid diffuser there is an exchangeable, inner diffuser. It has a conic shaped inlet and outlet and it suitably matches the capacity of the burner. The job of the solid horizontal plate is to ensure the even spread of the mixture of gas and air to the ceramic heating cooker hob.
The heating cooker hob, according to the invention, has holes, peripheral gaps and tunnels. This enables cooling the bottom of the burners, the support bracket, fumes tunnels, the set of electric valves, the electric steering module, the control-indicating panel, and even some parts of a ceramic plate. This does not allow the parts of the plate to overheat. This was also one of the main reasons for starting the research on the project.
The ventilation system gives an opportunity to decrease a distance between the burners and the ceramic plate and this leads to the increase of the effectiveness of the heating cooker hob. All the fiimes from the heating cooker hob are directed to the outlet tunnel which enables to collect them through the ventilation of the room and this leads to an improvement and comfort of using the appliance.
The advantage of the gas burner, according to the invention, is the solid structure of the casing of the burner, a solid structure of the external diffuser and the injector not dependent on the capacity of the burner or the land of gas. The exchange of the inner diffuser as well as the gas nozzle enables the optimization of outflow of gas and air mixture keeping at the same time high efficiency of the burner and proper parameters of combustion.
