Description

Technical Field

Present invention relates to a flue chamber suitable for use in oven-type cooking devices and providing to discharge, in a reliable manner, air which is formed within the cooking compartment of the cooking device.

Prior Art

Oven-type cooking devices comprise at least one cooking compartment in which cooking process takes place and which, preferably, is heated by means of a heating element. When a cooking or heating process is performed within said cooking compartment, various gases may be formed depending on structure of the product being heated/cooked and characteristics of the heating element being used. For example, during cooking of a liquid containing food, steam is formed within the cooking compartment as a result of evaporation of the liquid. In addition to this, for example if a gas heater is used, gases such as carbon dioxide are formed due to burning of the gas. Such gases formed within the cooking compartment may negatively affect the cooking/heating process. For that reason, said gases should be removed from the cooking compartment.
In the known art, flue structures are used to send out the gases formed within the cooking compartment. Said flue structures comprise a flue which communicates with the cooking compartment on one side, and communicates with the outside on the other side through a body of the cooking device. Flue structures used in the cooking devices enables to practically discharge gases formed within the cooking compartment. However, since temperature of the gases formed within the cooking compartment is generally high (250 - 350°C), during release of these gases from the hearth plate flue outlet discharges on the hearth plate by means of a flue directly through the body of the cooking device, colour changes are caused especially at the hearth plate flue outlet region made of inox raw material.

Brief Description of Invention

The present invention provides a flue chamber suitable for use in a cooking device which comprises at least one cooking compartment and at least one flue communicating with the cooking compartment on at least one side. Said flue chamber comprises at least one body in the form of a hollow box which has at least one opening on at least one side, and at least one discharge hole on at least another side; at least one intermediate wall which is positioned in said body, partially closes said opening, and forms a discharge line between said discharge hole and the part of the opening that is not closed by the intermediate wall; at least one insulation element located between said intermediate wall and the body or between the intermediate wall and the opening, and having heat insulating properties; and at least one connection section located in said body and connecting the body to the cooking device through the opening.
In the flue chamber according to the present invention, hot air coming from the cooking compartment of the cooking device via the flue passes through a discharge line, which is formed by the intermediate wall in the body, so as to be sent to the outside through the discharge hole. In here, thanks to the insulation element located between said intermediate wall and the body or between the intermediate wall and the opening, temperature of the hot air, passing through the discharge line, on the intermediate wall is prevented from being transferred to the flue outlet section of the hearth plate by heat transfer. Therefore, deteriorations are prevented in a practical and reliable manner, which may be formed due to hot gas particularly at the hearth plate surface made of inox raw material.

Object of Invention

An object of the present invention is to develop a flue chamber suitable for use in oven-type cooking devices and providing to discharge, in a reliable manner, gases which are formed within the cooking compartment of the cooking device.
Another object of the present invention is to develop a flue chamber which prevents colour change, associated with the discharged gases, at the hearth plate surface of the cooking device made of inox raw material.
Yet another object of the present invention is to develop a durable and reliable flue chamber.

Description of Invention

For the oven-type cooking devices, gases which are formed within the cooking compartment during the cooking process should be discharged. Discharging said gases through a flue directly communicating with the body of the cooking device may cause particularly hearth plate of the cooking device made of inox raw material to get damaged. Therefore, with the present invention, there is developed a flue chamber for use in oven-type cooking devices and providing to discharge, in a reliable manner, gases which are formed within the cooking compartment of the cooking device, and being mounted to the flue outlet.
The flue chamber (S) according to the present invention, exemplary views of which are provided in figures 1-4, is suitable for use in a cooking device (P) which comprises at least one cooking compartment (P1) and at least one flue (P2) communicating with the cooking compartment (P1) on at least one side, the flue chamber comprising at least one body (1) in the form of a hollow box which has at least one opening (1a) on at least one side, and at least one discharge hole (1b) on at least another side; at least one intermediate wall (2) which is positioned in said body (1), partially closes said opening (1a), and forms a discharge line between said discharge hole (1b) and the part of the opening (1a) that is not closed by the intermediate wall; at least one insulation element (3) located between said intermediate wall (2) and the body (1) or between the intermediate wall (2) and the opening (1a), and having heat insulating properties; and at least one connection section (1d) located in said body (1) and connecting the body (1) to the cooking device (P) through the opening.
In an exemplary embodiment of the invention, the intermediate wall (2) positioned within the body (1) partially closes the opening (1a) which is located in the body (1). Here, in the body (1), a discharge line is formed between the discharge hole (1b) and the part of the opening (1a) that is not closed by the intermediate wall (2). At least another side of said flue (P2) which is not communicating with the cooking compartment (P1) is connected to the section of the opening (1a) that is not closed by the intermediate wall (2). In here, gases formed within the cooking compartment (P1) pass, respectively, through the flue (P2), the opening (1a), the discharge line formed within the body (1), and finally the discharge hole (1b) to be sent out. While said gases are discharged in this manner, the insulation element (3) (e.g. a glass wool) located between said intermediate wall (2) and the body (1) or between the intermediate wall (2) and the opening (1a) prevents the heat formed within the discharge line from being transferred to the cooking device (P). In other words, thanks to said insulation element (3), heat exchange between the section of the opening (1a) which is closed by the intermediate wall (2) and the cooking device (P) is blocked. Thus, hearth plate (P3) of the cooking device (P) is prevented to get damaged due to hot gases discharged from the cooking compartment (P1).
In a preferred embodiment of the invention, said intermediate wall (2) is in the form of a plate which is in connection with an upper wall (1c) of said body (1) on at least one side, and is inclined (in other words, having an acute angle with the upper wall (1c)) so as to approach to said opening (1a) as it moves away from the upper wall (1c). In this embodiment, said insulation element (3) is positioned at the face of the intermediate wall (2), which is in the form of a plate, facing to the opening (1a). In here, when the body (1) is connected to the cooking device (P), said insulation element (3) is between the intermediate wall (2) and the cooking device (P). By this way, a better heat insulation is provided between the cooking device (P) and the discharge line.
In another preferred embodiment of the present invention, said discharge hole (1b) is positioned at an upper wall (1c) of the body (1). Thus, it is provided to discharge gases, which are coming from the discharge hole, through the discharge hole (1b) in a simpler way. In this embodiment, said discharge hole (1b) is, preferably, aligned coaxially with the discharge hole of the hearth plate (P4).
Yet in another preferred embodiment of the present invention, said intermediate wall (2) is integral with the body (1). In an alternative embodiment, the intermediate wall (2) is attachable to and detachable from the body (1). In this embodiment, the flue chamber (S) comprises at least one connection lug (2a) located at the intermediate wall (2), and at least one connection element (4), preferably in the form of a screw, to connect said connection lug (2a) to the body (1). Therefore, the flue chamber (S) can be used in a simple and practical manner.
In another preferred embodiment of the present invention, said flue chamber (S) comprises at least one protective layer (not shown in the figures) located on the body (1) and having high thermal endurance. Said protective layer is preferably in the form of a dye having high temperature endurance. By this way, the body (1) is prevented from being damaged from the hot gas passing through the body (1).
In the flue chamber (S) according to the present invention, hot air coming from the cooking compartment (P1) of the cooking device (P) via the flue (P2) passes through a discharge line, which is formed by the intermediate wall (2) in the body (1), so as to be sent to the outside through the discharge hole (1b). In here, thanks to the insulation element (3) located between said intermediate wall (2) and the body (1) or between the intermediate wall (2) and the opening (1a), hot air passing through the discharge line is prevented from being transferred to the hearth plate (P3). Therefore, deteriorations are prevented in a practical and reliable manner, which are formed due to the hot gas at the hearth plate (P3) made of inox raw material.
