The operation and effect of the overheat-preventing automatic temperature correction method for the cooking vessel of the present invention of the gas range having the above-described configuration and steps will be described as follows.

First, a gas range to which the present invention is applied includes a power supply unit 1, a plurality of temperature sensors 2, a plurality of thermocouples 3, a display unit 4, a plurality of microswitches 5, a display unit 8, A known type of overheating prevention control device of the gas range, which is composed of the microcomputer 6 and the plurality of solenoid valves 7, is provided in the input terminal of the microcomputer 6 so that the consumer can select the type and material of the cooking container A cooking container type and a material selection unit 9 are additionally provided so that a consumer can select a container to be used for cooking in detail (that is, to select the type and material of the cooking container) .

In addition, in the present invention apparatus, the storage unit 8 under the control of the microcomputer 6 is provided with various cooking modes including a superheat prevention temperature (THicut = TN) set at a high cut temperature (MS, MA, MB) for determining different overheat preventing correction temperatures (THicut1) (THicut2) corresponding to the type and material of the container are stored, and various types and materials And the automatic overheating prevention function corresponding to the characteristics such as the type and material of the cooking container can be accurately performed when the cooking is performed using the various cooking vessels having the cooking cavity.

In this case, among the various components included in the overheat preventing control device of the known gas range, the power supply unit 1 normally performs a function of supplying power voltage to each part with a dry battery, and the temperature sensors 2 And the thermocouples 3 electrically detect whether or not the combustion is normally performed in each of the burners and transmit the detected result to the microcomputer 6, The display unit 4 includes a variety of information input by a consumer and performs various functions such as displaying various status information when cooking is performed through each burner.

The microswitches 5 are turned on / off corresponding to the rotation of the respective gas supply amount adjusting knobs and transmit the signals to the microcomputer 6. The storage unit 8 stores various control programs, In order to prevent the cooking vessel from overheating, different overheat preventing correction temperatures THicut1 and THicut2 are determined corresponding to the overheat preventing temperature (THicut = TN) set at the high cut temperature and the kinds and materials of the various cooking vessels. MA, and MB, and transmits the program and data when the microcomputer 6 requests the microcomputer 6. The microcomputer 6 may be a microcomputer or a microcomputer.

The microcomputer 6 performs a predetermined control program and controls the overall operation of the gas range. The solenoid valves 7 control the supply amount of the gas in response to the output signal of the microcomputer 6 Control and interrupting functions.

When the method of the present invention is performed in the gas range to which the apparatus of the present invention having the above-described configuration is applied, the microcomputer 6 first determines whether the consumer uses the cooking vessel type and material selection unit 9 for cooking It is determined whether the type and material of the container to be selected is selected (S1).

As a result of the determination, when the consumer selects the type of container to be used for cooking through the cooking container type and material selection unit 9, the type of the container is primarily stored in the storage unit 8 And sequentially determines which of the cooking vessels is inputted (S2).

Thereafter, the microcomputer 6 has a different value corresponding to the type of the cooking container inputted by the consumer out of the overheat correcting temperatures TF, TP, TS for the cooking vessels inputted into the storing unit 8 The predetermined overheat preventing correction temperature is determined as the first or final overheat preventing correction temperature THicut1 (S3).

At this time, the types of cooking containers that can be selected by the consumer can include various types such as a frying pan, a pot, a stone pot, and the like, and thus can not be limited thereto. In the present invention, A frying pan, a pot, and a stone pot, which were judged to be widely used, were presented for convenience.

Meanwhile, the first or final overheat correcting temperature THicut1, which is determined differently according to the type of the cooking container, is determined as the correction temperature TF, TP, TS determined according to each cooking container, , The value of the overheat preventing correction temperature THicut1 determined for each type of container is determined in the order of the frying pan (THicut1 = TF) <pot (THicut1 = TP) <stone pot (THicut1 = TS).

In this case, when the cooking vessel is a stone pot, due to the nature of the material, the risk of fire occurrence is relatively low as compared with a frying pan or pot. Therefore, the correction temperature (TS) determined according to the material characteristics of the stone pot is set to the final overheat- In the case of a frying pan or pan having a characteristic of easily overheating as compared with the stone pot, the correction temperatures TF and TP determined in correspondence with the respective container types are determined as the first overheat preventing correction temperature THicut1.

However, the overheat prevention correction temperature (THicut1 = TS) itself, which is set to the final overheat prevention correction temperature because the type of the cooking container is a stovepot, is not limited to the general type when the type and material of the cooking container are not selected by the microcomputer It is desirable to limit the temperature to a value lower than an overheat preventing temperature (THicut = TN, for example, 270 to 320 占 폚 immediately before the oil is ignited) set to the high cut temperature for the overheat prevention operation.

In the meantime, since the consumer selects only the type of container used for cooking through the cooking container type and material selection unit 9, the user can select the type of the cooking container inputted by the user, (S6), it is determined whether or not the ignition is performed in the burner on which the cooking container is placed.

As a result, if the user performs cooking after ignition, the temperature of the cooking vessel is detected in real time through the temperature sensor 2 in a state of being in close contact with the bottom surface of the cooking vessel while the cooking is being performed, It is continuously judged whether or not it is higher than the overheat prevention correction temperature THicut1 corresponding to the type of the first or last determined corresponding cooking vessel (S7).

If the current temperature of the corresponding cooking vessel is higher than the overheat preventing correction temperature THicut1 of the corresponding cooking vessel, which is determined first or finally, in the micom 6, If the temperature is higher than the finally determined overheat preventing correction temperature THicut1, the electromagnetic valve 7 connected to the burner for the cooking container is closed to immediately stop the fire due to overheating (S8).

In the initial stage S1, when the consumer selects both the type and the material of the container to be used for cooking through the cooking container type and the material selection unit 9, (TF, TP) stored in the storage unit 8, which are different from one another and are input to the storage unit 8, in order to determine which one of the cooking vessels is inputted to the storage unit 8 , TS) as a primary or final overheat preventing temperature (THicut1) corresponding to the type of cooking container input by the consumer.

Thereafter, the microcomputer 6 does not enter the step S6 of continuing to determine whether or not ignition is performed in the burner on which the corresponding cooking vessel is placed, and the material of the corresponding cooking vessel inputted by the consumer is stored in the storage unit 8 (Step S4). In step S4, it is determined which of the materials is input.

Then, the microcomputer 6 calculates a specific overheat corresponding to the material of the cooking container inputted by the consumer among the overheat-preventing correction temperatures MS, MA, and MB, Prevention correction temperature is firstly increased or decreased to a value determined by the cooking container-based superheat preventing correction temperature THicut1 as described above to determine the final overheat preventing correction temperature THicut2 (S5).

In this case, as a cooking container to be selected by a consumer, a frying pan or a pot may be selected, and a suitable material for the cooking container may be various materials such as stainless steel, aluminum, and enamel. However, in the present invention, stainless steel, aluminum, and enamel, which are judged to be relatively widely used as a material for a cooking vessel, are presented for convenience.

The correction temperatures MS, MA, and MB determined according to the respective materials of the cooking container (i.e., the frying pan or the pot) are set to the first overheat preventing correction temperature THicut1, which is determined differently according to the type of the cooking container, And the final final superheat preventing correction temperature THicut2 of the corresponding cooking vessel is automatically determined. Finally, the value of the final superheat preventive correction temperature THicut2, which is determined according to the type and material of each vessel, (THicut1 ± MA = THicut2) <stainless (THicut1 ± MS = THicut2) <enamel (THicut1 ± MB = THicut2) in consideration of the thermal conductivity.

Of course, the second final superheat preventing correction temperature THicut2 itself, which is set to the final overheat preventing correction temperature regardless of the type of the cooking vessel, is also controlled by the microcomputer 6 so that the type and material of the cooking utensil It is preferable to limit the temperature to a value lower than the overheat prevention temperature (THicut = TN; for example, 270 to 320 占 폚) set to the high cut temperature for the general overheat prevention operation.

Meanwhile, since the consumer selects both the type and the material of the container used for cooking through the cooking container type and material selection unit 9, the final preheating prevention correction temperature &lt; RTI ID = 0.0 &gt; (THicut2), it is determined whether or not the ignition is performed in the burner on which the cooking container is placed (S6).

As a result, if the user performs cooking after ignition, the temperature of the cooking vessel is detected in real time through the temperature sensor 2 in a state of being in close contact with the bottom surface of the cooking vessel while the cooking is being performed, (S7) whether the temperature is higher than the finally determined overheat preventing correction temperature (THicut2) according to the type and material of the cooking container selected by the consumer.

When the microcomputer 6 determines that the current temperature of the cooking container during cooking is higher than the overheat preventing correction temperature THicut2 of the corresponding cooking container finally determined as described above, If the temperature is higher than the correction temperature THicut2, the electromagnetic valve 7 connected to the burner for the corresponding cooking vessel is closed and immediately extinguished automatically (S8) in order to block the fire due to overheating.

In the initial stage S1, the consumer determines whether to select the type and material of the container to be used for cooking through the cooking container type and the material selection unit 9 connected to the input terminal of the microcomputer 6. As a result, The microcomputer 6 sets the high cut temperature input to the storage unit 8 to the overheat preventing temperature THicut = TN (e.g., 270 to 320 占 폚) (S9).

Then, it is determined whether or not ignition is performed in the burner on which the cooking vessel is seated (S6). As a result, if the consumer performs cooking after ignition, the temperature sensor The temperature of the cooking container is detected in real time through the heater 2 to continuously determine whether the current temperature is higher than the automatically set overheating prevention temperature THicut = TN at step S7.

As a result, it is determined that the present temperature of the cooking container is higher than the general high cut temperature (THicut = TN) (THicut = TN), the solenoid valve 7 connected to the burner for the corresponding cooking container is closed and immediately extinguished automatically (S8) in order to block the occurrence of fire due to overheating.

As described above, the gas range to which the present invention is applied can select the type and material of the container to be used for cooking in detail by the customer so that the automatic overheating prevention function can be accurately performed according to the characteristics of the cooking container It is possible to minimize problems such as difficulty in digestion and cooking failure during cooking, thereby solving the consumer's dissatisfaction at the time of cooking using the gas range, as well as greatly improving the convenience in cooking and the quality and reliability of the product.
