Description

A Method for Detecting and Warning the Leakage of Gas from Cook-Top Burners in Gas Oven Range

The present invention relates to a gas leakage alarm method for a stove burner of a gas oven, and in particular, a micro switch for detecting whether the control knob is turned on or off during automatic fire extinguishing due to overflow of soup when cooking in a stove burner of a gas oven. If the control knob is in the on state, the alarm sound so that the user can easily recognize the gas burner of the stove burner gas leakage method to prevent safety accidents due to gas leakage.

In general, a gas oven is a cooking appliance that combines a gas stove for cooking food and an oven for putting food in a cavity and cooking food using radiant heat and convection heat. The burner is ignited or turned off by the rotation of the formed adjustment knob.

4 is an exploded perspective view showing the cock portion for igniting or extinguishing the gas oven as described above, wherein the shaft insertion portion 12 and the grounding portion 14 are formed in the inner center of the adjusting knob 10. The adjusting knob shaft 16 which is engaged with the shaft inserting portion 12 of the knob 10 and the adjusting knob mounting groove 20 in which the micro switch 18 is mounted on one side of the knob 10 are integrally formed so that the mechanism cock 22 is formed. Is connected to.

The instrument cock 22 is connected to a gas supply pipe 24 for supplying gas and a thermocouple tube 26 integrally formed with a thermocouple for detecting a salt voltage from a flame of a burner.

Therefore, when the user pushes and rotates the adjustment knob 10 of the cock back, the adjustment knob 10 is rotated and the ground portion 14 presses the micro switch 18, and is coupled to the adjustment knob 10. As the push rod pushes the safety valve backward, gas is supplied to the burner through the gas supply pipe 24, and then an ignition transformer interlocked with the mechanism cock 22 is driven to ignite the gas supplied to the burner. .

However, when the burner is burned down automatically by the soup while cooking by rotating the control knob 10 formed on the cock of the gas oven range as described above, the salt voltage detected by the thermocouple is below a certain level. Then, the electromagnet that is opened by the thermoelectric power is closed and gas shutoff is possible, but there is a risk of gas leakage because the cock is open until the time that the rotating control knob 10 is rotated. If a problem occurs in the relay, there was a problem that a safety accident occurs due to the continuous leakage of gas.

The present invention is to solve the above problems, by using a stove burner of gas oven microwaves to detect whether the control knob is on or off when the stove burner is automatically extinguished by the overflow of the soup when cooking. Gas burner alarm method for gas burner of gas oven to prevent safety accidents due to gas leakage by alerting the user to easily recognize that control knob is on by installing switch. To provide that purpose.

In the present invention for achieving the above object in the stove burner gas leakage alarm method of the gas oven, when the combustion mode is performed by igniting the range burner to cook food, the control unit detects the salt voltage in the flame of the burner A first step of determining whether the salt voltage is detected through the thermocouple, If the salt voltage is detected at a constant level through the thermocouple in the first step, the control unit is a second step of continuing the combustion mode of the range burner, the first step When the salt voltage is detected to be below a predetermined level through the thermocouple, the controller determines whether the adjustment knob of the range burner is on or off, and if it is on, the controller controls the alarm to generate an alarm sound to indicate that the adjustment knob is on. And a third step of recognizing the user.

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

Figure 1 is an exploded perspective view showing a cock portion according to the present invention, the shaft insertion portion 12 and the ground portion 14 is formed in the inner center of the adjustment knob 10, the shaft insertion of the adjustment knob 10 The adjusting knob shaft 16 which is fastened to the part 12 and the adjusting knob installation groove 20 in which the first and second micro switches 30 and 40 are mounted on one side of the upper and lower sides are integrally formed. Connected to (22).

The instrument cock 22 is connected to a gas supply pipe 24 for supplying gas and a thermocouple tube 26 integrally formed with a thermocouple for detecting a salt voltage from a flame of a burner. Therefore, when the adjustment knob 10 is rotated to use the range burner, the ground part 14 is rotated while pressing the first micro switch 30 which recognizes the off state, and the second micro switch 40 is rotated. When pressed, the control unit (shown in FIG. 2) recognizes the on state by the operation of the second micro switch 40, and the push rod coupled to the control knob 10 then pushes the safety valve backward. As the gas is supplied to the burner through the gas supply pipe 24, the ignition transformer linked to the mechanism cock 22 is driven to ignite the gas supplied to the burner.

On the other hand, when the user reverses the adjustment knob 10 to extinguish the range burner, the grounding portion 14 formed on the adjustment knob 10 moves the first micro switch 30 from the second micro switch 40. The control unit recognizes that the adjustment knob 10 is turned off by pressing it.

Figure 2 is a block diagram schematically showing the configuration of the gas oven according to the present invention, the first and second micro switch 30, 40 is rotated by the adjustment knob 10 and the return operation according to the reverse rotation It is connected to the control part 50 so that the adjustment knob 10 may be in an on or off state, and the alarm part 60 which produces an alarm sound is comprised so that it may be controlled by the control part 50. FIG.

The operation and effects of the gas oven configured as described above will be described in detail with reference to the flowchart of FIG. 3.

When the user rotates the control knob 10 to cook food and ignites the range burner to perform the combustion mode of the range burner (101), the salt voltage is detected from the flame of the range burner where the thermocouple is ignited to detect this detection signal. When applied to the control unit 50, the control unit 50 determines the ignition state according to the applied salt voltage level (102), if a predetermined level of salt voltage is detected through the thermocouple, the control unit 50 stops cooking food The combustion mode of the range burner is continued (103).

On the other hand, when the salt voltage detected through the thermocouple is applied to a predetermined level or less, the controller 50 is applied to the second micro switch 40 or whether the OFF signal is applied from the first micro switch 30. If the on signal is continuously applied from the second micro switch 40 (104), the control unit 50 does not return even if the adjustment knob 10 of the range burner is extinguished. In response to the determination that the control unit 60 controls the alarm unit 60 to generate an alarm sound, the control knob 10 recognizes that the user is open even though the range of the burner is extinguished (105).

As described above, the present invention is equipped with a micro switch that detects whether the control knob is on or off when the burner is automatically extinguished during the combustion by the soup, etc., during cooking by rotating the adjustment knob of the gas oven. If the control knob is on during fire extinguishing, it generates an alarm sound, and the electromagnet that was opened by the thermal power is closed so that the gas can be shut off, but the cock is open until the control knob is rotated. It is possible to prevent safety accidents due to continuous leakage of gas in case of danger of abnormality and abnormality of relay for driving electromagnetic.
