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

The noodle cooking apparatus for a gas range equipped with a ramen cooking time setting function according to the present invention can be used not only for ramen noodles but also various noodles such as noodles, spaghetti, udon noodles, cold noodles, etc., which are fed into a cooking vessel, It can be used for cooking.

1, a gas valve 130 is installed in a gas pipe 120 for supplying a gas to a burner 110 and is opened and closed to supply gas to the burner 110 or to supply gas supplied to the burner 110 .

The valve driver 140 automatically locks the gas valve 130 when a gas shutoff signal is input.

The temperature sensor 150 closely contacts the bottom surface of the cooking vessel to sense the temperature of the cooking vessel while applying a thermal power to the cooking vessel placed on the burner 110 in order to boil the ramen.

The first timer 160 counts a predetermined water boil determination time Ta.

The second timer 160a counts a predetermined water boiling parallel holding time Tc.

The third timer 160b counts a predetermined waiting time Td to be turned on.

The fourth timer 160c counts the instant noodle cooking time Te set by the user.

The fifth timer 160d is a boiler in which water is introduced into the cooking vessel in the boiling state of water and then water or other food is added according to the user's taste and the boiling water required for returning to the boiling state after the sudden drop in temperature And counts the trial short time (Tf).

The microprocessor 170 starts counting the first timer 160 at the same time that the gas range initiates the ignition operation.

The microprocessor 170 determines that the water boil determination time Ta is less than the predetermined water boiling temperature 100 ° C after the start of the counting of the first timer 160, (Tb), the gas shutoff signal and the overheat alarm signal are output. When the water boil determination time Ta is equal to or more than a predetermined over-heating determination time Tb, the second timer 160a starts counting.

The microprocessor 170 outputs a water boil alarm signal when the water boiling temperature of the water boiling temperature (100 ° C) or more after the start of the counting of the second timer 160a is maintained for the water boiling parallel holding time Tc or more, Subsequently, the counting of the third timer 160b is started.

After the start of the counting of the third timer 160b, the microprocessor 170 puts the ramen soup and the ramen soup into the cooking container within the ramp-up wait time Td and sets the desired ramp-up cooking time Te If the user inputs a ramen noodle and ramen soup into the cooking container within the waiting time Td for entering the cooking ramp and sets the desired cooking time Te, The counting of the fourth timer 160c is started.

When the current temperature of the water in the cooking container after the start of the counting of the fourth timer 160c is equal to or higher than the water boiling temperature (100 ° C), the microprocessor 170 outputs a gas shut- And outputs a cooking end signal.

The microprocessor 170 starts counting the fifth timer 160d after the start of the counting of the fourth timer 160c when the current temperature of the water in the cooking container is not equal to or higher than the water boiling temperature 100 ° C , An additional correction time Tg is calculated by a predetermined formula and then the additional correction time Tg is added to the rampage cooking time Te to extend the cooking time, And outputs a shutoff signal and a cooking completion signal.

It is preferable that the additional correction time Tg is calculated by the following equation and the following equation is calculated by the applicant (or the inventor) in the process of inventing the cooking device for the gas range according to the present invention If the cooking time (Te) is in the range of 3 to 5 minutes, water or other food such as eggs, kimchi, etc. is added depending on the user's taste while the water is boiling. (Tf), which is required to return to the water boiling state again, is repeatedly measured, and the optimum value of the degree of perfection of the cooking can be maintained in comparison with the average value of the measured water boiling time (Tf) And is set to calculate the additional correction time Tg.

In the above formula (1), Te is the cooking time and Tf is the shortened cooking time.

The alarm unit 180 generates an overheating alarm when the overheating alarm signal is input, generates a water boil alarm when the water boil alarm signal is input, generates a cooking failure alarm when the cooking failure alarm signal is input, If the cooking end signal is inputted, a cooking end alarm is generated.

The alarm unit 180 may be an equalization alarm device (for example, LED or FND) for generating an alarm by lighting or blinking operation, a voice alarm device for generating an alarm by outputting an alarm sound or a voice message )to be.

The cooker 100 for a gas range having the function of setting the ramp-up time according to the present invention configured as described above operates as follows.

2 and 3, the user first selects a ramen cooking start button (or a switch) provided in the gas range while placing a cooking container containing water on the burner 110 in order to boil the ramen (S100) , The ignition switch is turned on (S112).

When the user turns on the gas valve 130 while the gas valve 130 is opened, the ignition switch supplies the gas to the burner 110 and ignites the gas to generate a flame. When the gas valve 130 is switched off, Shut off the gas.

4, the temperature sensor 150 is attached to the bottom surface of the cooking container so as to sense the temperature of the cooking container, It is preferable that the jaw is provided on the panel together with the ignition switch.

The cooking start button (or switch) illustrated in FIG. 4 is set so that the user can select the most frequently used ramen cooking time Te for four minutes when the user presses the center ramp button. The cooking time Te can be set to 3 minutes or 5 minutes according to the preference of the user.

The ramen cooking start button (or the switch) described above can be easily and variously installed on the operation panel of the gas range at an expert level in the related art, unlike the example shown in FIG. For example, the cooking time Te can be freely set if the user is in the range of 3 to 5 minutes in seconds, 10 seconds, 30 seconds, or minutes.

In the state where the gas range is ignited after the cooking start button (or switch) of the gas range is selected as described above, the microprocessor 170 firstly starts the ignition operation of the gas range, and at the same time the first timer 160 (S114).

For reference, the water boil determination time Ta is a time required until the present temperature of the water in the cooking vessel starts to become equal to or higher than the water boiling temperature (100 ° C), and the temperature sensor 150 ) Is preferably set to a time required for the current temperature of the cooking container to be detected to be about 95 DEG C or higher. When 120 g is used, 550 mL of water is used for cooking one (including ramen soup) The water boil determination time (Ta) is preferably set to 3 minutes.

After the start of the counting of the first timer 160, the microprocessor 170 determines whether the current temperature of the water in the cooking container after the start of the counting of the first timer 160 is equal to or higher than the water boiling temperature (100 ° C) (S116).

If the current temperature of the water in the cooking container after the start of the counting of the first timer 160 is determined to be equal to or higher than the water boiling temperature (100 ° C), the microprocessor 170 calculates the water boil determination time Ta Is greater than or equal to the predetermined overheating determination time Tb (S118).

For example, 550 g of water may be used to cook one of the above 120 g (including ramen soup), for example, when the overheating determination time Tb is shorter than the water boil determination time Ta. , It is preferable that the water boil determination time Ta is shorter than 3 minutes and less than 3 minutes.

If the overheating determination time Tb is determined to be within 3 minutes, the current temperature of the water in the cooking vessel should be equal to or higher than the water boiling temperature (100 deg. C) within 3 minutes after the first timer 160 starts counting , It is determined that the water in the cooking vessel is rapidly heated in a short period of time and is in a boiling overheated state.

Therefore, if the water boil determination time Ta is not equal to or greater than the predetermined overheating determination time Tb, that is, if the water in the cooking vessel is above the boiling water temperature (Ta) before the predetermined water boiling determination time Ta (S118), the microprocessor 170 outputs a gas shutoff signal and an overheat alarm signal (S120, S122).

At this time, the valve driver 140 automatically locks the gas valve 130 so as to safely and automatically extinguish the gas range, and the alarm unit 180 generates an overheating alarm. As a result, the boiling water overflow accident, Or a fire accident that may occur due to overheating of the cooking vessel can be prevented.

Alternatively, if the water boil determination time Ta is equal to or greater than the predetermined overheating determination time Tb, that is, if the water in the cooking vessel is not more than the water boiling temperature 100 ° C after the predetermined water boil determination time Ta (S118), the microprocessor 170 starts counting the second timer 160a (S124).

After the start of counting of the second timer 160a, the microprocessor 170 determines whether boiling of the water boiling temperature (100 deg. C) or more is continued for the water boiling parallel holding time Tc or not (S126).

For reference, the water boil parallel holding time Tc is a time for maintaining the water boiling temperature (100 ° C) or more continuously in the state where the water in the cooking vessel starts to boil, It is preferable to set the time to about 10 to 20 seconds (for example, 15 seconds) when 550 ml of water is used for cooking one (including ramen soup) for 120 g.

If it is determined that the water boiling temperature of the water boiling temperature (100 ° C) or more is maintained longer than the water boiling parallel holding time Tc (S126), the microprocessor 170 outputs a water boil alarm signal, 3 timer 160b (S128, S130).

At this time, the alarm unit 180 generates a water boil alarm, and as a result, it is confirmed that water is boiled even if the user is waiting around the gas range or leaving the gas range, and the ramen and ramen soup are put into the cooking vessel do.

After the start of the counting of the third timer 160b, the microprocessor 170 inserts the ramen soup and the ramen soup into the cooking container within the ramping-on waiting time Td, (S132).

For reference, the ramp-on waiting time (Td) is a time required for the user to put the ramen soup and ramen soup in the cooking container and set the desired cooking time (Te), and immediately after the above- (For example, 120 seconds) when 550 ml of water is used to cook one (including ramen soup) if it is 120 g, for example.

If the user puts the ramen soup and the ramen soup into the cooking container and does not set the desired cooking time Te in step S132 within the waiting time Td, And outputs a cooking failure alarm signal (S134, S136).

At this time, the valve driver 140 automatically locks the gas valve 130 so as to safely and automatically extinguish the gas range, and the alarm unit 180 generates a cooking failure alarm. As a result, It is possible to improve the completeness of the cooking by preventing the situation where the cooking fails in advance.

If a cooking failure alarm occurs, it is preferable that the user start cooking again from the beginning, if the user further replenishes the cooking vessel with water.

Alternatively, if the user inserts the ramen noodles and ramen soup into the cooking container within the ramping-on waiting time Td and sets the cooking time Te desired by the user, the microprocessor 170 sequentially outputs the fourth timer (Step 138).

After the start of the counting of the fourth timer 160c, the microprocessor 170 determines whether the present temperature of the water in the cooking container is equal to or higher than the water boiling temperature (100 ° C), that is, It is determined whether the water in the container continues to boil at a water boiling temperature (100 DEG C) or more (S140).

If the water in the cooking vessel continues to boil above the water boiling temperature (100 ° C) immediately after the ramen and ramen soup are introduced into the cooking vessel (S140), the microprocessor 170 continues to perform the above- Similarly, it is determined whether the cooking time Te set by the user has been set (S142).

If the cooking time Te set by the user is reached, the microprocessor 170 outputs a gas shutoff signal and a cooking completion signal at steps S144 and S146.

At this time, the valve driver 140 automatically locks the gas valve 130 so as to safely and automatically extinguish the gas range. When the alarm unit 180 is activated, a cooking end alarm is generated. As a result, If you are on standby or leaving the gas range, you will be notified that the cooking has finished.

Alternatively, if the water in the cooking vessel does not continue to boil above the water boiling temperature (100 ° C) immediately after the ramen and ramen soup are introduced into the cooking vessel (S140), the microprocessor The count of the fifth timer 160d is started (S148).

In the present invention, if the water in the cooking vessel does not continue to boil at a water boiling temperature (100 ° C) or higher immediately after the ramen and ramen soup are introduced into the cooking vessel as described above, Depending on the user's taste, water or other food such as eggs, kimchi and the like is added to the water, the temperature of the water falls sharply and falls down.

After the start of the counting of the fifth timer 160d, the microprocessor 170 calculates an additional correction time Tg in accordance with a predetermined equation (S150).

At this time, it is preferable that the additional correction time Tg is calculated by the above-mentioned equation (1).

When the additional correction time Tg is calculated, the microprocessor 170 extends the cooking time by adding the calculated additional correction time Tg to the ramen cooking time Te set by the user as described above When the extended cooking time has elapsed (S152), the gas shutoff signal and the cooking completion signal are output (S154, S156).

At this time, the valve driver 140 automatically locks the gas valve 130 so as to safely and automatically extinguish the gas range. When the alarm unit 180 is activated, a cooking end alarm is generated. As a result, If you are on standby or leaving the gas range, you will be notified that the cooking has finished.

In particular, if the cooking time is extended by adding the additional correction time (Tg) automatically calculated to the user-set ramen cooking time Te as described above, and if the cooking is finished, By avoiding a failure situation in advance, the perfection of the cooking can be further improved.

5, the graph of FIG. 5 shows the water temperature change state in the cooking container during operation of the cooking device for the gas range with the ramping time setting function according to the present invention.

FIG. 5 (a) is a view showing a state in which water in the cooking container continues to boil at a temperature of water boiling (100 ° C.) after the ramen and ramen soup are put into the cooking container as described above, When the time Te is reached, the cooking is terminated.

FIG. 5 (b) is a diagram illustrating a state in which the temperature of the water drops sharply as the user adds water or other food according to the user's taste after the ramen and ramen soup are put into the cooking vessel as described above, An additional correction time Tf is added to the user-set ram surface cooking time Te, and the cooking is terminated if the time elapses.

It is to be understood that the present invention is not limited to the above-described embodiment, but may be modified and changed without departing from the spirit and scope of the present invention, There is a technical spirit to the extent that anyone with ordinary knowledge in the field to which it belongs can make various changes.
