Description

How to prevent overheating of gas stove cook-top burner

The present invention relates to a method of preventing overheating of a gas oven, in particular, when a cook-top burner of a gas oven is ignited, a cooking time is counted, and an alarm is generated when the counted cooking time reaches a preset time. To require the user to take the necessary measures, and if no action is taken in spite of the alarm sound, the gas oven stove cooktop burner is overheated to prevent the cooktop burner from overheating by shutting off the gas supplied to the gas oven. It relates to a prevention method.

In general, a gas oven is a cooking apparatus in which a conventional gas stove for cooking food and an oven for cooking food in the cavity using radiant heat and convective heat are combined.

Figure 4 is a perspective view showing a general gas oven operating as described above, Figure 5 is a side cross-sectional view of the gas oven stove shown in Figure 4, the gas oven stove is located on top of the gas oven (1) A cooktop burner (2) used to cook the same food, an oven burner (4) mounted in a cavity (3) located below the cooktop burner (2) and used to cook food such as bread, and fish Grill burner 5 is used to cook food, such as is equipped.

The gas oven 1 configured as described above is driven and controlled by the ignition knob 7 of the operation panel 6 formed on the front surface. That is, when the handle 7 is rotated, gas is supplied to the corresponding burner by the mechanism before the MPU is driven by the thermocouple, and at the same time, the ignition transformer is driven to ignite the gas supplied to the burner. In addition, when the cooking of the food is completed and the user rotates the handle 7 in reverse, the fuel supply to the burner is blocked, so that the ignited burner is extinguished.

However, in the case of cooking food using the conventional gas oven as described above, if the user forgets the cooking room of the food, the food being cooked will be burned off, and the container containing the food will not be overheated and used. There is a problem that a fire may occur.

In order to eliminate the risk of fire as described above, a timer for setting a cooking time is installed in the oven part and the grill part of the conventional gas oven. Therefore, when the set cooking time has elapsed, the supply of gas to the oven / grill burner is stopped and the fire due to overheating can be prevented. However, the cooktop burner is not equipped with a device for preventing overheating, and a timer or In the case of mounting the sensor, as the number of burners should be installed, there was a problem in that it acts as a factor that increases the production cost of the product.

Accordingly, the present invention has been made to solve the above problems, the cooking time when the cook-top burner of the gas oven is ignited, counting the cooking time, the alarm when the counted cooking time reaches a predetermined time If no action is taken despite the alarm sound, the solenoid valve installed between the gas inlet and the governor of the gas supply pipe is turned off to turn off the gas oven. It is an object of the present invention to provide a method of preventing overheating of a gas oven stove cooktop burner by blocking a gas supplied to the cooktop burner.

In order to achieve the above object, the present invention, in the overheat prevention method of the cooktop burner is applied between the gas inlet of the gas supply pipe and the governor is applied to the gas oven range having a solenoid valve for controlling the supply of gas, the user After the solenoid valve driving switch is turned on to supply gas to the gas oven, after rotating the ignition knob to ignite the burner, the first step of counting the cooking time and the cooking time counted in the first step A second step of determining whether the preset reference value has been reached; and when the cooking time counted in the second step reaches the preset reference value, an alarm is generated to request the user to take necessary measures and to switch the time extension switch. And a third step of determining if the time extension switch is turned on within a predetermined time in the third step. And extending the time by a predetermined time and turning off the solenoid valve when the time extension switch is turned off, thereby cutting off the gas supplied to the gas oven.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically showing a configuration of a gas oven to which the present invention is applied, and FIG. 2 is a view showing a mounting position of the solenoid valve of FIG. 1.

As shown in the figure, between the gas inlet 120 and the governor 90 of the gas supply pipe 110 is equipped with a solenoid valve 60 for controlling the gas flowing into the gas oven, the solenoid valve ( 60 is drive controlled by the output signal of the controller 50.

In addition, a thermocouple 20 that is heated by the flame of the ignited burner and generates thermoelectric power and a drive switch 10 for driving the solenoid valve 60 by the user are connected to the controller 50, respectively. The thermoelectric power generated by the thermocouple 20 is supplied to the MPU 30 to maintain the gas flow into the burner.

On the other hand, the controller 50 has a function of counting the food cooking time after the burner is ignited, and comparing the counted cooking time with a predetermined reference value. As a reference value, as most foods are cooked within 1 hour, the gas oven may be set for 1 hour or other appropriate time, and may be set by the user through a separately installed key input unit.

The cooking time counted by the controller 50 is provided to the user through the display unit 80, and when the counted cooking time reaches a preset reference value, the alarm unit 70 generates an alarm sound according to the control signal of the controller 50. Instruct the user to take the necessary action. On the other hand, the time extension switch 40 is for increasing a predetermined reference value.

Next, an overheat prevention method of the cooktop burner according to the present invention applied to the gas oven configured as described above will be described in detail with reference to FIG. 3.

When the user turns on the driving switch 10, the solenoid valve 60 is driven to supply gas to the gas oven (101). When the user rotates the ignition knob while the gas is supplied to the gas oven, the gas is supplied to the corresponding burner by the mechanism war and the ignition transformer is driven to ignite the gas supplied to the burner (102).

When the burner is ignited, the controller 50 counts the cooking time and compares the counted cooking time with a preset reference value (103 to 104). In this case, the counted cooking time is provided to the user through the display unit 80.

When the counted cooking time reaches a preset reference value, the controller 50 generates an alarm sound and requests the user to take necessary measures (105), and determines the switching state of the time extension switch 40 (106). . When the time extension switch 40 is turned on within a predetermined time, the controller 50 maintains the on state of the solenoid valve 60 for a preset time to maintain a gas supply state to the gas oven ( 106).

On the other hand, when the time extension switch 40 maintains the off state so that a predetermined time elapses, the controller 50 determines that the user is absent and turns off the solenoid valve 60. Therefore, as the gas supply to the gas oven is stopped, the cooktop burner is turned off.

As described above, the present invention counts the cooking time when the cook-top burner of the gas oven is ignited, and generates an alarm when the counted cooking time reaches a preset time to take necessary measures. If no action is taken despite the alarm sound, the cooktop burner is switched off by turning off the solenoid valve mounted between the gas inlet of the gas supply line and the governor. To prevent overheating.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
