Definitions
- the present invention relates to an oven comprising an oven burner and a grill burner that are operated controllably.
- two different burners namely the oven burner and the grill burner
- the oven burner provides the foods placed into the cooking chamber to be cooked slowly and homogeneously and the grill burner provides a faster and regional cooking.
- a different partition is provided for each of the two burners in some ovens, the two burners are generally positioned around the same cooking chamber.
- the two burners operating simultaneously inside the same volume in gas ovens creates danger in terms of the user.
- various control systems are utilized. The most widespread of these are systems comprising two-way thermostats and/or two-way taps. In these systems, although the amount of gas delivered to the oven burner can be adjusted, the amount of gas delivered to the grill burner cannot be adjusted and the grill burner is always operated at the highest level. This results in ineffective utilization of the grill section and unnecessary consumption of energy.
- a cooking device comprising an oven burner and a grill burner is described.
- the gas source is connected to the burners by two different lines.
- An electromagnetic valve controlled by an electric thermostat is disposed on the line leading to the oven burner and a gas thermostat and a deflection valve are disposed on the line leading to the grill burner.
- the aim of the present invention is the realization of an oven comprising more than one burner that can be controlled independently from each other and prevented from operating simultaneously.
- the oven realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises an oven burner and a grill burner disposed in the vicinity of the cooking chamber.
- the gas coming from the gas source split into two lines, one going to the oven burner and the other to the grill burner.
- a valve is situated on each line.
- Each of the valves is opened/closed by means of a switch.
- the switches are disposed on the body of the oven in the section where the door is closed and change to the pressed position when the door is closed.
- the first valve connected to the oven burner allows passage of gas when the door is closed while the second valve connected to the grill burner does not allow passage of gas when the door is closed.
- the first valve does not allow passage of gas but the second valve allows while the door is open.
- the cutoff valves although appearing the same from the outside, operate in reverse effect with respect to one another due to the differences in their gas passage channels located therein. Thus, the two burners are prevented from operating simultaneously.
- the amounts of gas delivered to the oven burner and the grill burner are adjusted by two different knobs situated on the panel.
- the burning intensity of the grill burner can be adjusted independently from the oven burner and this provides the effective utilization of the grill section.
- the oven comprises a solenoid valve between the first valve and the oven burner.
- the solenoid valve continues to ignite the oven burner by means of the ignition plug whereto it is connected through the coil.
- the oven burner is ignited automatically and the user does not need to ignite again.
- the safety problems are eliminated that may occur in the situation the user forgets to perform ignition upon closing the door after completing intervention to the food by opening the door.
- the oven comprises a sensor disposed on the oven burner and that detects the temperature of the oven burner.
- the temperature detected by a bulb-shaped sensor connected to the solenoid valve, increases as the oven burner starts to burn and the solenoid valve stops ignition process of the oven burner as this increase is detected.
- the temperature detected by the sensor falls down in the course of time.
- this value falls below a value predetermined by the manufacturer, it is decided that the cooking process has ended. In this situation, the solenoid valve stops the ignition of the oven burner.
- the gas amounts delivered to the oven burner and the grill burner can be adjusted by two separate knobs and it is guaranteed that both burners are not operated simultaneously.
- Figure 1 – is the perspective view of the oven.
- Figure 2 – is the front partial perspective view of the oven.
- Figure 3 – is the rear partial perspective view of the oven.
- Figure 4 – is the perspective view of the control circuit components.
- Figure 5 — is the cross-sectional view of the first valve when the door is closed.
- Figure 6 — is the cross-sectional view of the first valve when the door is open.
- Figure 7 — is the cross-sectional view of the second valve when the door is closed.
- Figure 8 — is the cross-sectional view of the second valve when the door is open.
- the oven (1) comprises a cooking chamber (2) wherein the cooking process is performed, a door (3) providing access into the cooking chamber (2), an oven burner (4) and a grill burner (5) disposed in the vicinity of the cooking chamber (2), whereat the burning process is performed as the gas delivered from a gas source (S) is ignited.
- the oven burner (4) is disposed at the lower side of the cooking chamber (2) and provides the required heat for cooking the foods placed into the cooking chamber (2).
- the grill burner (5) is disposed at the ceiling of the cooking chamber (2) and enables the foods placed thereunder to be cooked with the grill effect ( Figure 1, Figure 2, and Figure 3).
- the oven (1) of the present invention comprises,
- the oven burner (4) and the grill burner (5) can be controlled independently from one another.
- the first valve (6) and the second valve (8) are connected parallel to the gas source (S). While the door (3) is closed, the first switch (7) and the second switch (9) are actuated and the first valve (6) and the second valve (8) are activated ( Figure 2, Figure 3, Figure 4).
- the first valve (6) allows passage of gas to the oven burner (4) while the first switch (7) is pressed on and cuts off the gas delivered to the oven burner (4) when the first switch (7) is not pressed on.
- the second valve (8) allows passage of gas to the grill burner (5) while the second switch (9) is not pressed on and cuts off the gas delivered to the grill burner (5) when the second switch (9) is pressed on. Even though the first valve (6) and the second valve (8) look very much alike in outer appearance, their inner structures are entirely different from one another.
- the first switch (7) while in free position, stops the passage of gas by interrupting the connection between the valve inlet and the valve outlet, and when actuated, allows passage of gas by opening the path between the valve inlet and the valve outlet.
- the second valve (8) operates in a manner opposite to the first valve (6).
- the switches (7, 9) of both of the two valves (6, 8) are pressed on while the door (3) is closed, the first valve (6) allows passage of gas and the second valve (8) does not.
- the door (3) is open, while the second valve (8) allows passage of gas, the first valve (6) does not. Consequently, in both positions of the door (3), the oven burner (4) and the grill burner (5) are prevented from operating simultaneously.
- the oven (1) is provided to be utilized in a safe manner ( Figure 5, Figure 6, Figure 7, and Figure 8).
- the oven (1) comprises a panel (10) situated on the front surface of its body, a first knob (11) disposed on the panel (10) and that enables the adjustment of the amount of gas delivered to the oven burner (4) and a second knob (12) disposed on the panel (10) and that enables the adjustment of the amount of gas delivered to the grill burner (5).
- the first knob (11) is positioned between the gas source (S) and the first valve (6) and the second knob (12) between the gas source (S) and the second valve (8).
- the amount of gas coming from the gas source (S) is delivered to the valves (6, 8) by adjusting the knobs (11, 12) and the valves (6, 8) control guiding of the gas to the burners (4, 5) depending on the position of the door (3).
- the two burners (4, 5) can be controlled flexibly and independently from one another ( Figure 1, Figure 2).
- the oven (1) comprises a solenoid valve (13) that provides the ignition of the oven burner (4) even if the gas delivered to the oven burner (4) is cut off when the door (3) is opened while the oven burner (4) is operating.
- the door (3) is opened for checking the state of the cooking food while cooking is performed by means of the oven burner (4) inside the cooking chamber (2).
- the first valve (6) does not allow passage of gas to the oven burner (4).
- the solenoid valve (13), disposed between the first valve (6) and the oven burner (4) provides ignition of the oven burner (4) to be continued by means of the ignition plug it controls.
- the door (3) is closed, the user does not need to perform the ignition again and the cooking process is resumed (Figure 2, Figure 3, Figure 4).
- the oven (1) comprises a sensor (14) that provides the detection of the temperature of the oven burner (4).
- the solenoid valve (13) provides ignition to be stopped when the temperature of the oven burner (4) starts increasing.
- the solenoid valve (13) provides the ignition to be stopped when the temperature of the oven burner (4) falls below a limit value predetermined by the manufacturer when the door (3) is opened while the oven burner (4) is operating. Thus, it is decided that the cooking process is desired to be ended and the igniter is prevented from operating unnecessarily.
- the oven burner (4) and the grill burner (5) are provided to be operated selectively depending on the position of the door (3). Consequently, both burners (4, 5) are prevented from operating simultaneously and the cooking process can be performed in a safe manner. Furthermore, the amount of gas delivered to both burners (4, 5) can be adjusted independently from one another and this provides flexibility of utilization.
