Description

An alarm cook gas-range}

[0001] The present invention relates to an alarm cook gas range, and more particularly, to an alarm cook gas range capable of automatically recognizing that water is boiled and preventing water from evaporating and causing a fire.

Conventionally, when boiling water using a cooking vessel containing water by using a gas range, a function of discriminating and notifying boiling water is realized.

As an example, water boiling using the conventional gas range as shown in FIG. 1 will be described as follows.

Among the conventional technologies relating to the gas range water boiling apparatus, there is Korean Patent No. 1,256,476, which is a cooking device for a gas range.

Korean Patent No. 1,256,476 discloses a method in which a temperature sensor senses a temperature of a cooking vessel while a thermal power is applied to a cooking vessel containing water for boiling a ramen, A water boil determination time, a ramen ramming wait time, a ramen ramen cooking time, and a ramen ramen cooking end determination time, which are set in order to determine whether or not the cooking is completed, are monitored through a timer to alert the user that the water in the cooking vessel has boiled If the water is completely boiled after the ramen is poured into the cooking vessel, it is alarmed that the cooking is completed and the gas range is automatically extinguished. If the water is completely boiled, the firepower of the gas range is automatically weakened until the cooking is completed, And then repeating the process of strengthening it.

1, the microprocessor 170 starts counting the first timer 160 when it is determined that the present temperature of the cooking container is equal to or higher than a predetermined timer operation start temperature (Low_T) (for example, 70 degrees Celsius).

The microprocessor 170 determines that the current temperature of the cooking vessel after the start of counting of the first timer 160 is equal to or higher than a predetermined water break determination start temperature High_T If the count value is stored as the cooking time setting time Ta, the current temperature of the cooking container is stored as the first measuring temperature T1 (e.g., 95 deg. C or more) and then the counting of the second timer 160a is started.

The microprocessor 170 stores in the internal memory the water boil determination time Tb corresponding to the ramp cooking time setting time Ta set as the count value of the first timer 160 and the waiting wait time Tc, The time Td, and the ramp-surface-cooking-end determination time Te.

The microprocessor 170 determines that the present temperature of the cooking container after the start of counting of the first timer 160 is less than a predetermined water break determination start temperature High_T (e.g., 95 deg. C) It is determined again that the current temperature of the cooking vessel is equal to or higher than a predetermined water break determination start temperature (High_T) (e.g., 95 deg. C) if it is determined that the temperature is lower than the timer operation starting temperature (Low_T)

The microprocessor 170 determines that the present temperature of the cooking container after the start of counting of the first timer 160 is less than a predetermined water break determination start temperature High_T (e.g., 95 deg. C) If it is determined that the temperature is lower than the timer operation start temperature (Low_T) (e.g., 70 deg. C), the first timer 160 starts counting again after determining that the current temperature is equal to or higher than the timer operation start temperature (Low_T).

The microprocessor 170 determines that the present temperature of the cooking container after the start of counting of the second timer 160a is greater than a predetermined water boiling determination temperature change value? T1 (for example,? 5 占 폚) ) Is greater than or equal to a predetermined first boiling water determination time TbSET1 (for example, 10 seconds) in correspondence to the cooking time setting time Ta or the count start of the second timer 160a If the present temperature of the cooking container is less than a preset value T1 of the water boiling judgment temperature change ΔT1 (eg, Δ5 ° C.) and the current count value of the second timer 160a is the cooking time setting time Ta (For example, 30 to 60 seconds) corresponding to the predetermined second water boil determination time TbSET2 corresponding to the predetermined water boil determination time TbSET2.

Korean Patent No. 1,256,476, which is a prior art, discloses that the water in the cooking container is boiled during the cooking of the ramen, so that it is possible to solve the conventional inconvenience that the user waits in the vicinity of the gas range and checks whether the water boils If the water is completely boiled, it is alarmed that the cooking is completed and the gas range is automatically extinguished. Therefore, even if the user leaves the gas range, it is possible to prevent the ramen from being blown. If the ramen is ripe, The firepower of the gas range can be automatically adjusted, thereby eliminating the conventional inconvenience that the user must manually adjust the firepower manually.

However, when the boiling water is boiled for 5 liters or more, for example, there is a problem that the user makes a mistake on the processor to notify the user that water is boiling even though the water does not boil.

In other words, in the prior art as described above, since the boiling water is discriminated and informed through a single uniform processor without considering the specific situation, it is judged incorrectly when there is a change in the amount of water, There was a problem telling me that it was boiling.

In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, the definitions of these terms should be described based on the contents throughout this specification.

First, the overall structure is introduced.

The alarm cook gas range of the present invention is provided in a gas pipe for supplying gas to the gas range and has a valve for opening and closing the gas transfer.

The MPU (MPI) controls the opening and closing of the valve so that the gas supply can be turned on and off.

The proportional unit (not shown) serves to adjust the fire power of the gas range and the micro-thermal power.

The temperature sensor is provided in the gas range and detects the temperature of the bottom of the cooking vessel.

The operation switch judges the boiling water in the cooking vessel and adjusts the processor to shut off the gas.

As shown in FIG. 3, the first processor can determine whether the water inside the cooking container is boiled or not.

The second processor as shown in FIG. 4 judges the second water boil when the water inside the cooking container is not boiled in the first processor.

As shown in FIG. 5, when the water inside the cooking container is not boiled in the second processor, the third processor determines the third water boil.

On the other hand, when it is determined that any one of the first processor, the second processor, or the third processor has boiled water in the cooking container, the gas supply is stopped while generating an alarm.

1. Description of the first processor

The first processor performs a first step of determining whether the water boiling start temperature (S120) has been reached when the gas range is ignited (S100) and water boiling is started through the operation switch S110 and is set to the water boiling start time (S130) .

More specifically, the water boiling start temperature S120 is measured, and at the same time, the time at which the water boiling start temperature S120 is measured is set.

For example, the temperature is set to 0 seconds while the temperature inside the cooking vessel is detected at 72 degrees Celsius.

Next, a second step is performed to compare the sum of the inter-temperature deviations measured repeatedly for a predetermined time interval after the first step with a predetermined temperature.

More specifically, the predetermined time interval in the second step may be 10 seconds.

The temperature is measured continuously from 10 seconds to 90 seconds at intervals of 10 seconds, and the temperature is continuously measured at 8 intervals. When the sum of the temperature deviations of the eight measured intervals is equal to or greater than 28, the first water boil It is determined whether the recognition condition is S150.

For example, if the deviation between the temperatures measured in intervals of 90 seconds to 10 seconds is less than 5 degrees Celsius and the condition is the same as the first interval, i.e., 90 seconds to 100 seconds, and the condition is 130 seconds to 130 seconds The water boil is terminated and an alarm (S210) is given to shut off the gas.

2. Description of the second processor

As shown in FIG. 4, the second processor performs a first step of determining a water boil start time (S130) while determining whether the water boil start temperature (S120) has been reached.

When the gas range is ignited (S100) and water boiling is started through the operation switch S110, it is determined whether the water boiling start temperature (S120) is reached and set to the water boiling start time (S130).

And a second step of determining whether the sum of the deviation of the temperature repeatedly measured for a predetermined time interval after the first step and the predetermined condition of water boiling discrimination (S140) that compares the predetermined temperature with each other is satisfied.

If the sum of the temperature deviations in the second step is less than the preset temperature, a third step of determining the processor regression determination condition (S160) is performed.

At this time, when the first water boiling state or the first water boiling state (S150) is entered after the third step, the deviation value between the temperatures measured between the first measurement temperature and the last measurement temperature for a predetermined time is below a predetermined temperature, If the difference in the final measured temperature is less than or equal to the predetermined temperature, water boiling is terminated and the alarm (S210) is given to stop the gas supply.

For example, if the sum of the temperature deviations of 8 intervals of 10 seconds to 90 seconds from 10 seconds to 90 seconds is less than 28, the temperature of the temperature deviation of 4 intervals of 10 intervals (for example, 80 seconds to 120 seconds) If the sum is greater than or equal to 10 and the temperature measured by the temperature sensor at 120 seconds is greater than or equal to 103 degrees Celsius and the temperature measured at the temperature sensor is greater than or equal to 112 degrees Celsius at 150 seconds, If satisfied, first determine whether it is a boil or a condition (S150).

 For example, if the temperature difference is less than 5 degrees Celsius for 5 periods from 90 seconds to 10 seconds, and the temperature difference between the first and last condition is less than 7 degrees Celsius, To shut off the gas.

3. Description of the third processor

As shown in FIG. 5, the third processor has a first step of setting the water boil start time (S130) while discriminating whether the water boil start temperature (S120) has been reached.

And a second step of determining whether the sum of the deviation of the temperature repeatedly measured for a predetermined time interval after the first step and the water boiling discrimination primary condition (S140) which compares the predetermined temperature with each other is satisfied.

If the sum of the temperature deviations in the second step is less than the preset temperature, a third step of determining the processor regression determination condition (S160) is performed.

If the processor regression determination condition (S160) is not satisfied in the third step, the second water boil recognition condition (S190) is set to measure the second boil water temperature (S170) and the second water boil recognition time (S180) The fourth step is to enter.

If the difference between the measured temperatures between the first measured temperature and the last measured temperature after the fourth step is less than or equal to the predetermined temperature and the difference between the initial measured temperature and the last measured temperature is less than the preset temperature, (S200) for a period of time equal to or longer than a predetermined time (S200), and then stops water boiling and an alarm (S210) to stop the gas supply.

The processor regression determination condition (S160) is such that the sum of the temperature deviations of the four sections is equal to or more than 10 at intervals of 10 seconds from 80 seconds to 120 seconds, and the temperature of the cooking vessel measured from the temperature sensor at 120 seconds And the temperature of the cooking container measured from the temperature sensor at the time of 150 seconds is greater than or equal to 112 degrees Celsius.

The second water boiling temperature (S170) may be set to, for example, a second water boil condition (S190) while setting the cooking vessel temperature measured by the temperature sensor to 113 degrees Celsius, .

For example, if the temperature difference is less than 1 degree Celsius for 5 intervals from 0 second to 10 seconds, and the temperature difference between the first and last condition is 1 degree Celsius, the gas supply is continued for a certain period of time (S200), water boiling is terminated and an alarm (S210) is given to shut off the gas.

On the other hand, when the temperature measured by the temperature sensor is less than or equal to 60 degrees Celsius, the first processor, the second processor and the third processor are initialized.
