According to the burner to determine the presence of cooking utensils to drive the ignition circuit driving unit 132 and to ignite, and when the burner temperature from the temperature measuring unit 102 is a set high temperature temperature alarm driving circuit driving unit 133 alarm sound It generates a, it is composed of a microcontroller 110 for blocking the gas by driving the valve circuit driver 131.

Here, the microcontroller 110 is a temperature input unit 111 for converting the burner temperature input from the temperature measuring unit 102 into digital data, and the current temperature input from the temperature input unit 111 and the set overheating reference. By comparing the temperature and the overheat temperature determination unit 112 to determine whether the overheat temperature, the timer 113 for counting and supplying a set time, and converting the signal input from the cooking utensil sensor 103 into a digital signal Is a cooking utensil sensing input unit 114, a cooking utensil judging unit 115 for determining whether a cooking utensil is placed on a burner based on the data output from the cooking utensil sensing input unit 114, and the operation setting input unit 104. In response to the overheat input from the operation setting input processing unit 116 and the overheating determination temperature 112 for inputting a user's operation setting through), an alarm sound is generated and input from the cooking utensil determination unit 115. Outputs the valve drive signal by the operation control unit 117 for outputting the alarm sound, valve drive or automatic ignition drive signal, and the control of the overheat temperature determination unit 112 or the operation control unit 117 according to the cookware or not. The valve driving unit 118 which cuts off gas supply, the automatic ignition driving unit 119 which generates a drive signal of the ignition device under the control of the operation control unit 117, and the alarm sound under the control of the operation control unit 117 Alarm sound generating unit 120 for outputting the generation signal.

4 is a flow chart of the ignition control process according to the detection of the cooking utensils of the gas range according to an embodiment of the present invention, when the micro-controller 110 detects the auto-ignition method and determines the presence of cooking utensils and proceeds cooking by auto ignition If the automatic ignition cooking process (S111 ~ S125), and the manual ignition method is detected in the microcontroller 110 to determine the presence of cooking utensils and proceed to the manual ignition cooking process (S131 ~ S135) to proceed with cooking through manual ignition The automatic ignition cooking process (S111 ~ S125) is a first step (S111) for detecting the presence of cooking utensils on the burner of the gas range, and the automatic ignition after a set time (Δt) when the cooking utensils are detected It consists of a second step (S121) (S122), and a third step (S123 ~ S125) to automatically extinguish when the detected overheating temperature is detected during the automatic ignition cooking is carried out, the manual ignition cooking process (S131 ~ S135) silver A fourth step (S131) (S132) of generating an alarm sound when cooking utensils are detected on the burner of the gas range; and a fifth step of stopping cooking of the alarm sound and cooking when manual ignition is made after the alarm sound is generated ( S133) (S134), and the sixth step (S135) to automatically extinguish when the overheating temperature is detected during the cooking process after the manual ignition.

A detailed operation of the ignition control method according to the cooking appliance detection of the gas range according to the embodiment of the present invention configured as described above will be described in more detail with reference to FIGS. 3 and 4.

First, the present invention allows the user to select the automatic ignition or manual ignition method in the case of the automatic ignition method when the cooking utensils are detected on the burner to perform the cooking by the automatic ignition method, even if the manual ignition method does not need cooking utensils In addition to ignition, cooking is carried out by manual ignition when the cooking utensils are raised.

4 is a flow chart of the ignition control process according to the cooking utensil detection of the gas range according to an embodiment of the present invention, the user first selects the automatic ignition method or manual ignition method using the operation setting input unit 104 to proceed with cooking (S101)

When the user selects the automatic ignition method through the manipulation setting input unit 104, the microcontroller 110 inputs a signal whether the cooking utensil is placed on the burner of the gas range through the cooking utensil sensor 103. If it is determined that the cooking utensil is placed by the cooking utensil sensing input unit 114, the operation control unit 117 counts the time supplied from the timer 113 (S111).

The operation control unit 117 controls the ignition circuit driving unit 132 through the automatic ignition driving unit 119 to ignite and cooks when a predetermined time Δt supplied from the timer 113 elapses. (S122-S123)

The predetermined time Δt may be set to 3 to 5 seconds or more in the operation control unit 117 as the auto ignition waiting time after the cooking utensil is detected.

When the cooking temperature is determined to be an overheating temperature by comparing the current temperature input from the temperature input unit 111 with a preset overheating temperature in the overheat temperature determining unit 112, the operation control unit 117 is the valve driving unit 118. To output the valve control signal to cut off the gas supply. (S124) (S125)

On the other hand, if the cooking utensil is removed from the burner at any time during the cooking process, that is, if the cooking utensil is not detected by the cooking utensil burner at the cooking utensil judging unit 115, the operation control unit 117 may operate the valve driving unit 118. After extinguishing the valve through the control, it generates an alarm sound to alert the user. (S112) (S113)

Even when the cooking is completed, if the user removes the cooking utensils from the burner, automatic fire extinguishing is made and the cooking ends after the alarm.

If the user selects the manual ignition method through the operation setting input unit 104, the operation control unit 117 receives the cooking utensil presence signal detected through the cooking utensil sensor 103, and indicates that the cooking utensil is on. When it is determined, an alarm sound is generated through the alarm alarm generating unit 120 to alert the user that the user is waiting for ignition in the manual mode (S131).

After the user confirms the alarm sound, the user directly proceeds to cooking after manual ignition. (S133) (S134)

When the cooking utensils are removed from the burner by the user during the cooking process, the cooking utensils 115 maintain the ignition state without automatic extinguishing even when the cooking utensils are not detected.

When the cooking temperature is determined to be an overheating temperature by comparing the current temperature input from the temperature input unit 111 with a preset overheating temperature in the overheat temperature determining unit 112, the operation control unit 117 is the valve driving unit 118. To output the valve control signal to cut off the gas supply.

As described above, the ignition control method according to the cooking apparatus detection of the gas range according to the present invention compares the current temperature detected at any time during cooking with a preset overheating temperature regardless of the automatic or manual ignition method, and when it is determined to be overheating, the valve driving unit 118. Drive the automatic fire extinguishing to prevent accidents.

In addition, although specific embodiments of the present invention have been described and illustrated above, it will be apparent that the present invention may be variously modified and implemented by those skilled in the art, such as various applications such as a gas oven, an electric range, and the like. It's work.
