Abstract
The present invention relates to a system for a gas oven having an improved air flow plate and connection thereof whereby the extinguishing of the bottom heating element is prevented. The present invention more particularly relates to a gas oven (1) comprising a burning chamber in which a bottom burner unit (2) is situated, said bottom burner unit (2) being delimited from below by a bottom air flow plate (4) in the manner that an intermediate space (9) in air flow communication with the burning chamber is formed between said bottom air flow plate (4) and a bottom plate (3) of the gas oven (1), air circulating through said intermediate space (9) to said burning chamber through air flow holes (5) located on said bottom air flow plate (4).
Description
The present invention relates to a system for a gas oven having an improved air flow plate and connection thereof whereby the extinguishing of the bottom heating element is prevented.
It is well-known that the bottom air flow plate carrying the bottom broiler in gas ovens can be deformed into a curved shape due to the high operating temperatures. The deformation of the air flow plate can cause the air flow holes on said plate to close, thereby depriving the flame in the boiler of air and causing the flame to be extinguished.
Among others, a prior art publication in the technical field of the invention may be referred to as US2016153667, which discloses a cooking appliance including a cooking chamber, wherein the cooking chamber comprises a bottom wall, a top wall and a gas burner disposed under the bottom wall. The bottom wall includes an opening opposite the gas burner. The cooking appliance includes a plate disposed in the cooking chamber, above the gas burner, a space between the plate and the bottom wall forming a passage for flow of the burnt gases coming from the gas burner.
The present invention, on the other hand, addresses the situation where the bottom air flow plate is fixed relative to the bottom plate to ensure that the air flow holes remain open and the broiler flame receives the desired air flow. In addition, as the amount of oxygen in the broiler chamber will remain in the desired range, the quality of combustion will improve and the formation of carbon monoxide due to incomplete burning will be minimized, resulting in a more environmentally friendly gas oven.
The present invention provides a system for a gas oven having an improved air flow plate and connection thereof, as provided by the characterizing features defined in Claim 1.
Primary object of the present invention is to provide a system for a gas oven having an improved air flow plate and connection thereof whereby the extinguishing of the bottom heating element is prevented.
The present invention proposes a gas oven with a bottom burner unit under which a bottom air flow plate allows air intake from an intermediate space through air flow holes. A bottom plate is provided below said bottom air flow plate as separated by said intermediate space.
Said bottom plate’s position relative to the bottom air flow plate is maintained by physical barriers in the form of spacing means extending along the distance between the bottom plate and the bottom air flow plate in the intermediate space.
The spacing means are preferably connection screws fixedly attached to the bottom air flow plate in the manner to be extending in the direction of said bottom plate.
Alternatively or additionally, the spacing means are hollow cylindrical elements extending along said intermediate space such that their upper end fit around the peripheral line of said air flow holes and they allow air passage thanks to their wire mesh structure in air communication with the intermediate space and opening to said air flow holes.
Accompanying drawings are given solely for the purpose of exemplifying a gas oven, whose advantages over prior art were outlined above and will be explained in brief hereinafter.
The drawings are not meant to delimit the scope of protection as identified in the Claims, nor should they be referred to alone in an effort to interpret the scope identified in said Claims without recourse to the technical disclosure in the description of the present invention.
The drawings are only exemplary in the sense that they do not necessarily reflect the actual dimensions and relative proportions of the respective components of the system if not otherwise stated explicitly.

The following numerals are assigned to different part numbers used in the detailed description:
1) Gas oven
2) Bottom burner unit
3) Bottom plate
4) Bottom air flow plate
5) Air flow hole
6) Spacing means
7) Connection hole
8) Connection screw
9) Intermediate space
The present invention proposes a gas oven (1) having a bottom burner unit (2) supported relative to a bottom air flow plate (4). Air flow through bottom burner unit (2) is facilitated by said bottom air flow plate (4) through a plurality of air flow holes (5) placed thereon.
According to the present invention, bottom air flow plate’s (4) vertical position is maintained relative to a bottom plate (3) of the gas oven (1) by a plurality of spacing means (6) preventing blocking of said air flow holes (5) as will be delineated hereinafter.
The bottom air flow plate (4) in air communication with an intermediate space (9) in between said air flow plate (4) and said bottom plate (3) ensures that the air flow holes (5) opening to said intermediate space (9) remain unblocked. However, it is possible that the bottom plate (3) in gas ovens deforms into a curved shape due to the high operating temperatures in the region. The deformation of the bottom plate can cause the air flow holes (5) on said plate to close, thereby depriving the flame around the bottom burner unit (2) of air and causing the flame to be extinguished.
According to the present invention, the bottom air flow plate (4) is separated from the bottom plate (3) such that the air flow holes (5) remain open and the bottom burner unit (2) receives the desired air flow, which also ensures that the amount of oxygen in the burning chamber remains in the desired range.
According to a preferred embodiment of the present invention, the spacing means (6) are realized by connection screws (8) mounted on connection holes (7) in the manner that deformation of the bottom plate (3) is prevented when the curved shape of the bottom plate (3) at the initial stage of its curving movement is stopped by the tip portions of the connection screws (8), thereby preventing blocking of the air flow by closing of the air flow holes (5) due to the high operating temperatures.
According to a further preferred embodiment of the present invention, the spacing means (6) are formed around said air flow holes (5) in the form of cylindrical elements (not shown) extending along said intermediate space (9). In this particular embodiment, cylindrical bodies of the spacing means (6) are made of wire mesh material supported by a durable material body portions, allowing air to pass through the wire mesh and leave the intermediate space (9) from the upper open ends of the cylindrical bodies at the air flow hole (5) portions.
This configuration is more advantageous compared to spacing means (6) in the form of connection screws (8) because in extreme and rare conditions, it can be possible that the bottom plate (3) is punctured by the tip portions of the connection screws (8). On the other hand, it is to be noted that the connection screws (8) still provides a very effective, practical and cheaper solution to the aforementioned problems.
In one aspect of the present invention, a gas oven (1) comprising a burning chamber in which a bottom burner unit (2) is situated, said bottom burner unit (2) being delimited from below by a bottom air flow plate (4) in the manner that an intermediate space (9) in air flow communication with the burning chamber is formed between said bottom air flow plate (4) and a bottom plate (3) of the gas oven (1), air circulating through said intermediate space (9) to said burning chamber through air flow holes (5) located on said bottom air flow plate (4).
In a further aspect of the present invention, said bottom plate’s (3) position relative to said bottom air flow plate (4) is maintained by at least one spacing means (6) forming a barrier between said bottom air flow plate (4) and said bottom plate (3) in the intermediate space (9).
In a further aspect of the present invention, said at least one spacing means (6) is fixedly attached to the bottom air flow plate (4) and extends in the direction of said bottom plate (3) in the intermediate space (9).
In a further aspect of the present invention, said at least one spacing means (6) is a connection screw (8) mounted on a connection hole (7) on the bottom air flow plate (4).
In a further aspect of the present invention, tip portion of said at least one connection screw (8) extends in the direction of said bottom plate (3) in the intermediate space (9).
In a further aspect of the present invention, the spacing means (6) are formed by cylindrical elements extending along said intermediate space (9).
In a further aspect of the present invention, the cylindrical elements are hollow elements positioned to fit around the peripheral line of at least one of said air flow holes (5), said cylindrical elements being made of wire mesh material allowing air to pass through the wire mesh and leave the intermediate space (9) from the upper open ends of the cylindrical elements at the air flow hole (5) portions.
Therefore, the present invention ensures that the quality of combustion remains stable and the formation of carbon monoxide due to incomplete burning is prevented, resulting in a more environmentally friendly operation gas oven.
