Description

FIELD OF THE INVENTION[0001]The present invention refers to a gas flow directing device for burners of oven-type cooking appliances. More particularly, said gas flow directing device comprises innovative technical and functional features capable of better using gases from a combustion process, but mainly maximizing efficiency of heat exchange of burners with cooking utensils.[0002]More preferably, the present invention refers to a device to be used in cooking appliance burners having the ability to increase the residence time of hot gases under a utensil by means of reducing dissipation speed of said gases.BACKGROUND OF THE INVENTION[0003]As generally known by those skilled in the art, cooking appliances are used for heating cooking utensils, such as pans, dishes, frying pans, etc. To this effect, these appliances are provided with a series of burners over which said utensils for the preparations of food are disposed, wherein the configuration of said burners is intended to produce ...

AI Technical Summary

Benefits of technology

The present invention is a gas flow directing device for burners of cooking appliances. The device improves the functioning of the burners and solves the limitations of existing burners. It includes an innovative structure that increases the residence time of hot gases under a cooking utensil bottom, enhancing the exchange heat time and energy use. The device efficiently and evenly heats the cooking appliance by allowing the gas flow to propagate along the entire utensil surface through pathways designed to reduce propagation velocity and increase the time of hot gases under the utensil. In one embodiment, the device has a distribution wall configuration with a series of distribution helical-shaped walls or a plane geometry. Other forms and geometrical configurations can also be applied to the distribution walls.

Problems solved by technology

In this sense, in accordance with the state of the art, one may note that manufacturers of cooking appliances aim at developing burners capable of obtaining higher and more suitable heating of said utensils without increasing or wasting fuel once said proposals would render such appliances economically and ecologically inappropriate in modern market.

Consequently, this type of configuration leads to an increase in the consumption of fuel by virtue of loss of energy to the atmosphere.

Nevertheless, in spite of improving efficiency, it is noted that the hot gas flow still continues losing or exchanging heat with the atmosphere, thereby wasting heating energy from the cooking utensils.

In other words, it was verified that conventional state-of-the-art burners already made use of especially developed cooktops for increasing the use of energy coming from hot gases generated by burners but unfortunately they still kept losing a substantial amount of energy to the atmosphere.

Hence, those burners known in the art still consume more energy to make up for the energy loss to the atmosphere.

Nonetheless, as can be observed by those skilled in the art, such solutions are not capable of effectively increasing burner thermal efficiency and they still cause energy loss to the atmosphere since said flame-generated hot gases are still being dissipated to the atmosphere without reusing and / or contacting the cooking utensils.

Furthermore, it is noted that such burners comprise a substantially complex structure since adaptations in the connections and fuel-feeding tubes are required such that they may also rotate without risks of causing leakages.

In other words, such state-of-the-art burners present problems and constructional limitations affecting their construction in addition to increasing security risks during handling and functioning of cooking appliances.

More particularly, it can be observed that said cooking appliances do not comprise burners capable of carrying out a more efficient heat exchange with cooking appliances but which would disclose simplified construction structures with no risk of causing fuel leakage during functioning.
