Definitions
- 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.
- 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 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.
- the vertical, outside walls of the fumes tunnels are furnished with thermal insulation.
- the same kind of insulation has the control-indicating panel.
- 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 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 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.
- fig.1 presents the view of the heating cooker hob with gas burners and the fumes tunnels when the ceramic plate is removed
- fig.2 shows the cross-section of the heating cooker hob s
- fig.3 shows the cross-section of the burner
- fig.4 the view of the burner with helping accessories.
- the heating cooker hob has the support bracket 1 to which gas burners 2 are fixed and which have fumes tunnels 3 used for carrying the fumes away and directing them into the fiimes outlet 8, which is in the back top part of the heating cooker hob.
- the support bracket 1 around the gas burners 2 there are peripheral gaps 4, which enable the passage of air, cooling the bottom of the burners 2.
- the fumes tunnels 3 of the gas burners 2 are over the support bracket 1 within the distance that enables the air passage cooling the support bracket 1 and the fumes tunnels 3.
- the heating cooker hob there are holes 6 through which the air that cools the fumes passes, the fumes, which flow out from the fumes tunnels 3_through fumes outlet 8.
- a ceramic plate cover 7 On the top the heating cooker hob there is a ceramic plate cover 7 on which there is a decorative print informing about the position of heating areas and the steering indicator area.
- a control- indicating panel 10 used for the service of particular gas burners 2.
- Under the support bracket 1 there is a set of electric valves 11 giving the capacity for gas burners 2 and it is fixed in some distance from the support bracket 1, and the electric steering module 12 fixed to the supporter 13 is also within a distance from the support bracket 1.
- the air flowing from the bottom of the heating cooker hob goes through the gaps between the electric steering module 12 and the set of electric valves 11 cooling them and then it goes through the gaps 4 around the gas burners 2 and under the fumes tunnels S cooling me bottom of gas burners 2, the fumes tunnels 3, the support bracket 1 and is directed to the fumes outlet 8, where it is mixed with flowing out fumes, cooling them.
- the air flows also through additional holes 5 in the support bracket 1 cooling the fumes tunnels 3 and the control-indicating panel lO.Additional factor cooling the fumes is the air flowing through the back holes 6 situated in the back part of the support bracket 1. The air is mixed with fumes flowing out through the fumes outlet 8 of the heating cooker hob.
- a gas burner 2 has a casing 17 where in the upper part of it there is a ceramic heating element 18, in the middle part there is a solid horizontal metal plate 22, and to the bottom part of it the solid diffuser pipe 19 is fixed.
- the outlet of the solid diffuser pipe 19 is under a solid metal plate 22.
- injector 20 At the entrance of the solid diffuser pipe 19 there is an injector 20 and a gas nozzle 23.
- Additional equipment of the gas burner is the fumes tunnel 3, electrodes of the ignition spark 14 and 15, and the detecting flame electrode 16, which are placed over the ceramic heating element and used for starting and controlling the burner.
- the heating cooker hob is designed for furnishing a kitchen as well as it can serve as an element of a detached gas cooker.
- the advantage of the heating cooker hob is its high thermal efficiency and the possibility of carrying away all the fumes to the ventilation system of the room what improves the comfort of using the kitchen considerably.
- the advantage of the burner, according to the invention is ensuring the even outflow of gas and air mixture through the ceramic heating element of the burner as well as the possibihty of optimization of combustion parameters ensuring high efficiency of the burner at its different capacities and different kinds of gas.
