Description

[0001] “STOVE BURNER AND TRIVET SET’

[0002]

[0001] The present patent of invention refers to an assembly of a gas burner and trivet (which is the support of the utensils used for cooking food) in a "monobloc" structure, which can be applied both in traditional models of stoves (with one or more ovens) and in countertop models, popularly known as cooktops. This burner and trivet set in a monobloc structure presents particular characteristics that allow its manufacture both with materials commonly used in the current state of the art and with more "orthodox" materials; they enable the reduction of manufacturing costs for stoves and cooktops; facilitate the cleaning of stove tables through a design practically free of joints that could accumulate dirt; and increase operational safety during food cooking due to the trivet not moving unintentionally when the utensil is handled on it.

[0003] BACKGROUND OF THE ART

[0004]

[0002] Stove table assemblies are known in the state of the art, configuring the upper part of the stoves, which can be assembled from various components made of different materials.

[0005]

[0003] Structures assembled from various components tend to constitute the most expensive stove tables, as they make their manufacture complex, timeconsuming, and depend on the use of appropriate materials to withstand the severe conditions of high temperature gradients during food cooking. In addition, the assembly of the gas burner and trivet sets through several parts inevitably creates gaps between the assemblies that lead to places conducive to dirt buildup during stove use.

[0006]

[0004] In addition, stove tables in the current state of the art do not include trivets in their composition, and these trivets usually configure loose pieces that are only positioned on the stove table. In addition to this configuration not allowing a harmonious assembly of the stove table, it also causes difficulties in transporting the stove after manufacturing to the point of resale and then to the place of use (since it must be packed separately from the stove table so as not to damage it due to vibration during shipping), it can cause damage to the stove table due to friction between the table and the grate during the cooking process, in which the utensil is constantly handled by the person who is cooking, and it brings safety risks, as it is not fixed and can cause the cooking utensil to tip over onto the person who is cooking, causing serious bums and various adverse effects.

[0007]

[0005] The Brazilian patent document MU8601986-4U filed on September 26, 2006 and entitled "TABLE STOVE WITH INTEGRATED STRUCTURE" presents a constructive solution for the manufacture of tables for stoves in a monobloc piece, which has specific objectives unrelated to those of the present patent application. This document provides for the possibility of manufacturing the stove table with integrated trivets, but limiting the constructivity to the ceramic molding forming process, since it aims to present a monobloc structure entirely manufactured in single ceramic material.

[0008]

[0006] However, in a disadvantageous way, this prior art overlooks the possibility of manufacturing a monobloc set from different materials, limiting its constitution to ceramic material, which in turn is limited to a single ceramic material appropriate to the proposed manufacture, more specifically to the lithium aluminosilicate glass-ceramics in their compositions that are classically resistant to thermal shock, but which intrinsically have a lack of tenacity suitable for use and low resistance to mechanical traction stresses, which can lead to catastrophic failure due to fracture resulting from the impacts of cooking utensils on the table.

[0009]

[0007] Although the use of ceramic material in the composition of stove tables results in several technical and functional advantages, including the contribution to reducing manufacturing costs, it is not desirable for monoblock structures to be restrictively manufactured in ceramic, and especially in lithium aluminosilicate vitroceramic, the latter due to the high cost of the material, since the use of other materials may meet several demands required by the consumer market, which are not met by the full use of ceramic materials, even if the advantage of manufacturing more convenient and complete monoblock structures for obtaining stove tables is maintained. Thus, much is lost in term of versatility and cost reduction.

[0010]

[0008] Another disadvantage of the technology taught by the aforementioned patent document, which makes its practical application unfeasible, is the fact that the need to protect the table region for stoves that receive the products and utensils to be heated on the stove, such as pots, pans, kettles, among others, was ignored. Thus, any collision of these utensils with the trivets, as normally occurs in the daily life of a kitchen, easily damages the physical integrity of the table, especially the trivets that receive this direct contact and move on the table, and can scratch it or even knock the utensil against the user, causing serious accidents. This is because ceramic materials, despite having several advantageous characteristics, are not resistant to mechanical shocks and break easily (technically, they have low toughness), especially in regions where "sharp comers" and bumps occur, as is the case with state-of-the-art trivets.

[0011]

[0009] Thus, there is a gap in the current market for stove tables that is versatile for product composition in different configurations from different materials, and, in any project situation, enables cost reduction compared to equivalent or closer models; that provides greater ease of cleaning and less aesthetic damage to the stove table due to friction with the trivets (product with fewer moving parts); and that considerably reduces the risks of accidents due to unwanted movement of the trivets.

[0012]

[0010] In order to solve the drawbacks of the state of the art and fill the gap that currently exists, the present invention proposes an assembly of a gas burner and trivet (which is the support for the utensils used for cooking food) in a "monobloc" structure, which comprises a base, the burner(s) and the trivet(s) in one same piece, non-dismountable, regardless of which materials are used to make up each part of the monobloc structure.

[0013]

[0011] Accordingly, in order to make possible the composition of the trivets in high tenacity material, typically, but not exclusively, ceramic, it is an objective of the present invention to provide a burner and trivet set equipped with a damping system that acts together with the trivets of the stove table, in order to prevent damage to the trivets and avoid domestic accidents.

[0014]

[0012] It is also an objective of the present invention to provide a gas burner and trivet set equipped with a monobloc structure that allows a variety of different constructions, enabling the use of a single or different materials in the composition of this monobloc structure, according to each application need.

[0015]

[0013] It is another objective of this invention to provide a gas burner and trivet set in a monobloc structure that may include an insulation system or thermal sink in models that require dissipation or insulation of the heat transmitted through the burners in order to protect the base region of the table when it is made of material that is not very resistant to heat or thermal shocks, or to strong temperature gradients.

[0016]

[0014] It is also an objective of the present invention to provide a gas burner and trivet set in a monobloc structure that offers high aesthetic appeal and is easier to clean, in which the monobloc structure does not show seams between surfaces and allows the combination of various different materials, each with particular aesthetic and technical characteristics in relation to the others, in order to expand the options of design of the products and have fewer regions that are difficult to clean due to the buildup of dirt.

[0017]

[0015] Advantageously, the gas burner and trivet set in a monobloc structure of the present invention provides variable applications according to the needs of use through the choice of materials that will be used for forming the table, while at the same time presenting a product capable of greatly reducing the manufacturing costs of stove tables.

[0018]

[0016] The following are schematic drawings of a particular embodiment of the invention, whose dimensions and proportions are not necessarily the real ones, since the sole purpose of the drawings is to didactically present their various aspects, the scope of protection of which is determined only by the scope of the accompanying claims.

[0024] DESCRIPTION OF THE INVENTION

[0025]

[0021] As illustrated by the accompanying figures, the present invention describes a stove table (M) with a monobloc structure (E) with the junction point table - heat exchanger - component that undergoes heating (E), which is equipped with a burner and trivet set in a monobloc structure (2) applied in burner regions (4) and which comprises a support base for burners (1 ) and trivets (2.3). The trivets (2.3) are meticulously designed to maintain the correct distance from the household utensils (not illustrated) that are positioned on the burners (not illustrated) and to provide the highest thermal efficiency and the lowest possible emissions of polluting gases.

[0026]

[0022] The burner and trivet set in monobloc structure (2) can be manufactured from any convenient material commonly used in the state of the art, such as metal, ceramics, polymer, or any other more orthodox materials, such as rocks, plastics, glass, as long as they are not flame propagators. Similarly, the geometric shape of the monobloc structure (2) can also vary widely, and can have any shape convenient to the consumer market.

[0027]

[0023] Thus, the burners (not illustrated) and / or the trivets (2.3) included in the monobloc structure (2) can be manufactured either simultaneously with the manufacture of the base (1 ) or at different times, with the formation of the monobloc structure (2) being able to occur from different stages of the manufacturing process that result in obtaining the monobloc structure (2) from the integration or definitive assembly of the burners (not illustrated) and / or the trivets (2.3) together with the base (1 ), for example by assembly manipulating the thermal expansion of the components, allowing fitting and preventing disengagement, after the thermal equilibrium of the monobloc structure (2) has occurred.

[0028]

[0024] Thus, briefly, the burner and trivet set in a monobloc structure (2) can be obtained by the manufacture of a single physical body, or by the assembly of different elements that result in the monobloc structure (2) provided with a base (1 ) with burners and trivets (2.3) integrated into a single piece. In fact, the materials used in the manufacture of the base (1 ), burners and trivets (2.3) can be different from each other, depending on the configuration of the invention.

[0029]

[0025] The burners must be interpreted in the sense of configuring the structure that, on the table (M), enables the efficient exit of the combustion gases used to heat products (not illustrated) on the table (M), as the stove is used. Thus, the components that act to generate the heat used by the stove (not illustrated), with such heat being transmitted from the burners, can also vary widely according to the solutions already known from the state of the art.

[0030]

[0026] The table (M) also comprises a damping system (2.4) equipped with tenacious contact bodies (2.1 ) arranged on the trivets (2.3), in order to avoid physical contact between the trivets (2.3) and the cooking utensils (not illustrated), such as pots and other household items or food, to be positioned on the burner and trivet sets in a monobloc structure (2). In addition, preferably, the monobloc structure (2) also comprises bushing elements (2.2) arranged through the trivets (2.3), positioned between the tenacious contact bodies (2.1 ) and the damping system (2.4), all arranged on a support and mounting base (2.5).

[0031]

[0027] The trivets (2.3) can be configured in any geometric shape, including as already foreseen by the state of the art, and the various constructivities of the trivets

[0032] (2.3) are accompanied by the shape of the tenacious contact bodies (2.1 ) arranged on the trivets (2.3) to prevent their contact with utensils (not illustrated) to be heated on the table (M).

[0033]

[0028] Basically, each tenacious contact body (2.1 ) can be made of any material that has sufficient tenacity to withstand and absorb forces from minor collisions with the cooking utensils (not illustrated) positioned on the burner and trivet set in a monobloc structure (2), without harming its physical integrity and preventing the forces from these collisions from reaching the trivets (2.3). In an exemplary manner, without excluding any other type of material sufficiently tenacious for the same application, the tenacious contact bodies (2.1 ) are made of metallic material, such as stainless steel and enamelled iron-carbon alloys, so as to allow the trivets (2.3) to be made of materials of low toughness and impact resistance, such as ceramic materials.

[0034]

[0029] Each tenacious body (2.1 ) is connected to an upper end of a trivet

[0035] (2.3), and the number and shape of the upper ends may vary according to each configuration of the trivets (2.3) chosen for each stove model (not illustrated).

[0036]

[0030] Optionally, depending on the specific configuration characteristics of the monobloc structure (2), the table (M) can also comprise a thermal balancing system (3) equipped with thermal elements (3.1 , 3.2 and 3.3) installed in the burner and trivet set in a monobloc structure (2). This thermal balancing system (3) is applied to enable the use of different materials in the composition of the burner and trivet set in a monobloc structure (2), so that the thermal elements (3.1 , 3.2 and 3.3) act to dissipate the heat produced in the surroundings of the burners, before this heat is transferred to the base (1 ) of the table (M).

[0037]

[0031] Thus, there is the possibility of using less expensive materials to manufacture the base (1 ), such as tempered glass, porcelain tiles or several other common ceramic materials. In an exemplary way, if the base (1 ) is manufactured in stainless steel material, there will be no need to apply the thermal balancing system (3) on the table (M).

[0038]

[0032] Each thermal balancing system (3) comprises thermal elements (3.1 , 3.2 and 3.3) arranged between each burner and trivet set in a monobloc structure (2) and the base (1 ), so as to serve as a thermal barrier. These thermal elements (3.1 , 3.2 and 3.3) can have any convenient shape to be inserted between the burner and trivet set in a monobloc structure (2) and the base (1 ), according to each design of the monobloc structure (E), and are made of any convenient heat-dissipating material, preferably aluminum.

[0039]

[0033] Preferably, each thermal balancing system (3) comprises a spacer body (joined set 3.1 , 3.2 and 3.3) and reduced contact ends (3.4) arranged at the peripheral edges of the spacer body (joined set 3.1 , 3.2 and 3.3). Thus, the distancing body (joined set 3.1 , 3.2 and 3.3) is responsible for directly contributing to the dissipation of the heat that migrates from the burner and trivet set in a monobloc structure (2), towards the base (1 ), while the reduced contact ends (3.4) act to reduce the amounts of heat transferred to the thermal balancing system (3), due to its close and direct contact with the burner and trivet set in a monobloc structure (2), and from the thermal balancing system (3) to the base (1 ).

[0040]

[0034] In an exemplary way, the reduced contact ends (3.4) are configured in a wedge or similar format, arranged beyond the fitting regions of the thermal balancing system (3) with the base (1 ) and with the burner and trivet set in a monobloc structure (2).

[0041]

[0035] Also preferably, the thermal balancing system (3) comprises an upper face (3.1 ) that is not uniformly rectilinear, preferably being curvilinear, but can also comprise straight segments joined by different angles. This upper face implies the expansion of the contact surface of the thermal balancing system (3) with the environment, as it facilitates heat exchange, and also implies the retention of products (not illustrated) that may occasionally run off onto the table (M), as commonly occurs, for example, during cooking processes in culinary activities, preventing the rapid dissipation of these products (not illustrated) to the rest of the table (M).

[0042]

[0036] Similarly, the thermal balancing system (3) can also comprise a lower face (3.2) that is not uniformly rectilinear, preferably being curvilinear, but can also comprise straight segments joined by different angles. In this case, a lower face (3.2) that is not uniformly rectilinear implies the enlargement of the contact surface of the thermal balancing system (3), which may be convenient depending on the specific model designed to compose the table (M).

[0043]

[0037] Additionally, in a complementary manner, each thermal balancing system (3) may comprise a heat exchanger element (3.2) arranged under the thermal balancing system (3), to facilitate or speed up the dissipation of heat passing through the thermal device (3). This heat exchanger element (3.2) can be configured by any convenient heat exchanger known in the state of the art, provided that it can be conveniently associated with the heat balancing system (3).

[0044]

[0038] Each thermal balancing system (3) may comprise a heat exchanger fluid conductive body, and this fluid may be the ambient air itself, gases or cooling liquids, that is, this heat exchanger fluid should be interpreted broadly, encompassing both the ambient air and gases or cooling liquids, all known from the state of the art, according to the different construction configurations assumed by the heat exchanger (3).

[0045]

[0039] Similarly, the constructivity of the thermal balancing system (3) can vary widely, as known from the state of the art and according to each application requirement.

[0046]

[0040] A person skilled in the art will readily perceive several ways to carry out the invention from the description, without straying from the scope of the accompanying claims.
