Description

An alarm cook gas-range

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 boiling and preventing a fire due to evaporation of water in advance.

In the prior art, when water is boiled using a cooking container filled with water using a gas stove, a function is implemented to determine and notify the boiling of water when the water boils.

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

Among the prior art related to the gas range boiling device, there is a device for cooking ramen for a gas range, which is Korean Patent No. 1,256,476.

Korean Patent No. 1,256,476, which is a prior art, discloses that a temperature sensor detects the temperature of a cooking vessel while heat is applied to a cooking vessel containing water for boiling ramen, and a microprocessor detects the temperature change state of the cooking vessel while ramen is being cooked and ramen It alerts that the water in the cooking container is boiling by checking the ramen cooking time setting time, water boiling time, ramen input waiting time, ramen cooking time, and ramen cooking end judgment time set to determine whether or not cooking is finished through the timer. , After putting the ramen into the cooking container, it alerts that the ramen water has completely boiled and the cooking is over and the gas stove is extinguished automatically. It performs an operation that repeats the process of reinforcing with

That is, as shown in FIG. 1 , the microprocessor 170 starts counting the first timer 160 when it is determined that the current temperature of the cooking vessel is equal to or higher than the preset timer operation start temperature (Low_T) (eg, 70° C.).

The microprocessor 170 determines that the current temperature of the cooking vessel is higher than the predetermined water cutoff determination start temperature (High_T) (eg, 95°C) after the count starts of the first timer 160 , and the current temperature of the first timer 160 is determined. The count value is stored as the ramen cooking time set time Ta, and the current temperature of the cooking vessel is stored as the first measured temperature T1 (eg, 95° C. or higher), and then the counting of the second timer 160a is started.

The microprocessor 170 has a boiling determination time (Tb), ramen input waiting time (Tc), ramen cooking corresponding to the ramen cooking time setting time (Ta) set in the internal memory by the count value of the first timer 160 A time (Td) and a judgment time (Te) for determining the end of ramen cooking are stored.

The microprocessor 170 determines that the current temperature of the cooking vessel is less than a predetermined water cutoff determination start temperature (High_T) (eg, 95° C.) after the first timer 160 starts counting, and subsequently the current temperature of the cooking vessel is If it is determined that the timer operation start temperature (Low_T) (eg, 70 ℃) or more, it is determined again that the current temperature of the cooking vessel is the predetermined water cutoff determination start temperature (High_T) (eg, 95 ℃) or more.

The microprocessor 170 determines that the current temperature of the cooking vessel is less than a predetermined water cutoff determination start temperature (High_T) (eg, 95° C.) after the first timer 160 starts counting, and subsequently the current temperature of the cooking vessel is If it is determined that the timer operation start temperature (Low_T) (eg, 70° C.) is less than the current temperature, the count of the first timer 160 is restarted 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 current temperature of the cooking vessel exceeds a predetermined water boiling determination temperature change value (ΔT1) (eg, Δ5°C) after the counting starts of the second timer 160a, and successively the second timer 160a ) is greater than or equal to the first water boiling determination time (TbSET1) (eg, 10 seconds) predetermined in response to the ramen cooking time setting time (Ta), or the counting of the second timer 160a is started After determining that the current temperature of the cooking container does not exceed the predetermined water boiling determination temperature change value (ΔT1) (eg, Δ5°C), the current count value of the second timer 160a is successively determined as the ramen cooking time setting time (Ta) If it is determined that the predetermined second boiling determination time (TbSET2) (eg, 30 to 60 seconds) or more is corresponding to the above, a water boiling start alarm signal is output.

This prior art, Korean Patent No. 1,256,476, alerts the user that the water in the cooking container is boiling while cooking ramen, so it can solve the conventional inconvenience of having to check whether the water is boiling while waiting around the gas stove. In addition, it alerts that the ramen water has completely boiled and the gas cooker is extinguished automatically, so that even if the user is away from the gas range, the ramen can be prevented from pouring. Since the heating power of the gas stove can be automatically adjusted, the conventional inconvenience of having to manually adjust the heating power by the user can be eliminated.

However, in the prior art, when the amount of water to be boiled is, for example, 5 liters or more of water, the processor makes an erroneous judgment even though the water is not boiling, and informs the user that the water is boiling.

That is, since the prior art discriminates and informs the boiling of water through a single uniform processor discrimination method without considering a specific situation, inaccurate judgment is made when there is a change in the amount of water, and water is There was a problem telling me that it was boiling.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of the user or operator. Therefore, definitions of these terms should be described based on the content throughout this specification.

First, the overall configuration is introduced.

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

The MPU (MPU) may turn the gas supply on/off by controlling the opening and closing of the valve.

A proportional device (not shown) serves to adjust the fire power and fine heat power of the gas range.

The temperature sensor is provided on the gas stove and detects the temperature of the bottom of the cooking vessel.

The operation switch controls the processor for shutting off the gas by determining the boiling water in the cooking vessel.

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

The second processor as shown in FIG. 4 determines the second boiling of water when the water inside the cooking vessel does not boil 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 boiling of water.

On the other hand, when it is determined that the water inside the cooking vessel is boiled in any one of the first processor, the second processor, and the third processor, an alarm is generated and the gas supply is stopped.

1. Description of the first processor

When the gas range is ignited (S100) and boiling of water is started through the operation switch (S110), the first processor determines whether the boiling start temperature (S120) is reached and sets the boiling start time (S130) to the first step. .

In more detail, while measuring the boiling start temperature ( S120 ), the instantaneous time at which the boiling start temperature ( S120 ) is measured is set.

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

Next, after the first step, a second step of comparing the sum of the temperature deviations repeatedly measured for a predetermined time interval with a preset temperature is performed.

In more detail, the predetermined time interval of the second step may be 10 seconds.

If there is a 10-second interval between 10 and 90 seconds, there are 8 sections, and the temperature is continuously measured in 8 sections. It is determined whether it is a recognition condition (S150).

For example, the deviation between the temperatures measured in each of 5 sections at intervals of 90 seconds to 10 seconds is 5 degrees Celsius or less, and at the same time, the first section of condition recognition, that is, between 90 and 100 seconds, and the last section of condition recognition, 130 seconds to 140 seconds If the temperature difference between the sections is 7 degrees Celsius or less, boiling ends and an alarm (S210) is given and the gas is cut off.

2. Description of the second processor

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

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

After the first step, a second step of determining whether the water boiling determination primary condition ( S140 ) of comparing a preset temperature with the sum of the temperature deviations repeatedly measured during a predetermined time interval is satisfied is performed.

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

At this time, after the third step, the first water boiling recognition condition (S150) is entered, but the deviation value between the temperatures measured for a predetermined time between the first and last measured temperatures is less than or equal to the predetermined temperature, and the initial measured temperature and If it is satisfied that the difference between the last measured temperature is less than or equal to the preset temperature, the water boil ends and the alarm (S210) is given and the gas supply is stopped.

For example, if the sum of the temperature deviations of 8 sections at 10-second intervals from 10 seconds to 90 seconds is less than 28, in the processor regression discrimination condition (S160), for example, the temperature deviation of 4 sections at 10-intervals from 80 seconds to 120 seconds The sum is greater than or equal to 10, the temperature measured by the temperature sensor at 120 seconds is greater than or equal to 103 degrees Celsius, and the temperature measured by the temperature sensor at 150 seconds is greater than or equal to 112 degrees Celsius. If satisfied, it is first determined whether the water boiling recognition condition (S150) is satisfied.

For example, when the temperature deviation is 5 degrees Celsius or less for 5 sections with an interval of 10 seconds from 90 seconds, and the temperature difference between the first section of condition recognition and the end section of condition recognition is 7 degrees C or less, stop boiling and give an alarm (S210) shutting off the gas.

3. Description of the third processor

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

After the first step, there is a second step of determining whether the water boiling determination primary condition (S140) of comparing a preset temperature with the sum of the temperature deviations repeatedly measured during a predetermined time interval is satisfied.

When the sum of the temperature deviations in the second step is smaller than the preset temperature, the 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 boiling recognition temperature (S170) is measured and the second boiling recognition time (S180) is set at the same time as the second boiling recognition condition (S190). It goes through the fourth stage of entry.

After the fourth step, if the difference between the temperatures respectively measured for a predetermined period of time between the first measured temperature and the last measured temperature is equal to or less than a predetermined temperature, and the difference between the initial measured temperature and the last measured temperature is less than or equal to a preset temperature, After performing the boiling of water (S200) for the time of

The processor regression determination condition (S160) is, for example, the sum of the temperature deviations of 4 sections at 10-second intervals from 80 seconds to 120 seconds is greater than or equal to 10, and the temperature of the cooking vessel measured from the temperature sensor at the time point of 120 seconds is in degrees Celsius. It is greater than or equal to 103 degrees Celsius, and the temperature of the cooking vessel measured from the temperature sensor at 150 seconds is greater than or equal to 112 degrees Celsius and satisfies all three conditions.

The second boiling recognition temperature (S170) is, for example, after the cooking vessel temperature measured by the temperature sensor reaches 113 degrees Celsius, the second boiling recognition time (S180) is set to 0 seconds while the second boiling recognition condition (S190) will enter into

For example, when the temperature deviation is less than 1 degree Celsius during 5 sections with an interval of 0 to 10 seconds, and the temperature difference between the first section of condition recognition and the end section of condition recognition is less than 1 degree Celsius, gas supply is continuously provided for a certain period of time By doing so, after the water boiling (S200) is performed, the boiling ends and the alarm (S210) is given and the gas is cut off.

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

Although the above has been described with reference to a preferred embodiment of the present invention, those of ordinary skill in the art can variously modify and modify the present invention within the scope without departing from the spirit and scope of the present invention described in the claims below.
