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

2, when the cooking container 220 is placed on the burner 210, the temperature sensor 230 closely contacts the bottom surface of the cooking container 220 to sense the temperature of the cooking container 220.

When the defrosting temperature and the defrosting time for defrosting the frozen food are set by the defrosting switch of the gas range, the microprocessor 240 sets the first defrosting temperature lower than the defrosting temperature and the first defrosting temperature higher than the defrosting temperature Automatically set the lower second defrosting temperature.

The microprocessor 240 automatically sets the second thermal power smaller than the first thermal power when the first thermal power is set by the ignition switch of the gas range in the state where the thawing temperature and the thawing time are set.

The microprocessor 240 may automatically fire the gas-fired thermal power from the first thermal power to the second thermal power or from the second thermal power to the first thermal power for the defrosting time after the gas range starts the ignition operation with the first thermal power The defrosting operation is performed such that the temperature of the cooking container 220 sensed by the temperature sensor 230 is maintained at the defrosting temperature beyond the second defrosting temperature after the temperature of the cooking container 220 is raised to the first defrosting temperature, And outputs a defrosting completion signal when the defrosting time ends.

When the temperature of the cooking container 220 sensed by the temperature sensor 230 reaches the first thawing temperature after the gas range is ignited by the first thermal power, It is determined whether the temperature of the cooking container 220 is the second defrosting temperature at a time interval and whether the temperature of the cooking container 220 reaches the temperature of the cooking container 220 within a second predetermined time after the temperature of the cooking container 220 reaches the second defrosting temperature When the temperature of the cooking container 220 is lowered to the second defrosting temperature or lower than the second defrosting temperature It is determined again whether the temperature of the cooking container 220 is the second thawing temperature at the first time interval. If the temperature of the cooking container 220 is lower than the second thawing temperature Not Or if the temperature of the cooking container 220 does not rise above the discrimination temperature for reaching the defrosting temperature within the second time period after the second defrosting temperature is reached, a thermal power increase signal is output to control the gas range by the first thermal power The defrosting operation is repeated for the defrosting time.

The microprocessor 240 automatically extinguishes the gas range when the defrosting time ends, thereby preventing the defrosting state of the frozen food from deteriorating.

1, the microprocessor 240 automatically de-energizes the gas range by delivering a gas shutoff signal to the valve driver, wherein the gas valve is closed by a valve driver Thereby shutting off the gas supplied to the burner through the gas pipe. Alternatively, the microprocessor 240 turns off the ignition switch in a state in which the gas valve is opened, thereby automatically shutting off the gas supplied to the burner to thereby extinguish the gas range. The ignition switch and the gas valve controlled by the microprocessor in the field of gas range technology can easily understand its operation to the level of ordinary skill in the art, so that further detailed explanation is omitted.

When the defrosting completion signal is input, the defrosting completion notifying unit 250 notifies the defrosting completion of the frozen food to the outside.

The defrosting notifying unit 250 may be an equalizing notifying device (for example, an LED or an FND) for notifying completion of defrosting by lighting or blinking, a voice notification device for notifying completion of defrost by outputting a voice or voice message, Speakers, etc.).

The thawing temperature regulator 200 for a gas range according to the present invention configured as above operates as follows.

FIG. 3 is a flowchart showing an operation process of the thawing temperature control device 200 for a gas range according to the present invention.

The operation of the present invention assumes that the user inserts the frozen food into the cooking container 220 for defrosting.

3, when the defrosting temperature T and the defrosting time t for defrosting the frozen food are set by the defrosting switch of the gas range, the microprocessor 240 is lower than the defrosting temperature T (T2) higher than the first thawing temperature T1 (e.g., T-10 占 폚) and the first thawing temperature T1 (e.g., T-10 占 폚) and lower than the thawing temperature T ) (For example, T-3 占 폚) is automatically set (S10).

Although the thawing switch (or thawing button) is not shown in the figure, it can be understood that the thawing switch (or the thawing button) can be easily and variously installed on the operation panel of the gas range at a level of ordinary skill in the gas range.

The thawing temperature (T) and thawing time (t) may be set according to the kind of the frozen food by operating the thawing switch. For example, a method of setting the defrosting temperature T and the defrosting time t using the up / down button, a method of setting the defrosting temperature T (T) automatically displayed corresponding to the type of frozen food in the display device of the operation panel of the gas range And the defrosting time t are selected and set by the soft buttons displayed on the display device.

When the microprocessor 240 determines that the first thawing temperature T1 (e.g., T-10 占 폚) and the first thawing temperature T1 (e.g., T-10 占 폚) are lower than the thawing temperature T, The second defrosting temperature T2 (e.g., T-3 占 폚), which is higher than the defrosting temperature T, may be automatically set to various temperatures depending on the type of the frozen food.

When the first thermal power is set by the ignition switch of the gas range in the state that the defrosting temperature T and the defrosting time t are set as described above, the microprocessor 240 sets the second thermal power smaller than the first thermal power And the ignition operation of the gas range is started with the first thermal power from this time (S20).

1, when the user turns on the gas valve 160 while the gas valve 160 is open, the ignition switch supplies gas to the burner 110 and simultaneously ignites the flame And blocks the gas supplied to the burner 110 when it is switched off.

A method of setting the fire power of the gas range by operating the ignition switch can be variously implemented. For example, the ignition switch may be rotated to select a strengthening force or a weakening force. In this case, the strengthening force may be set to a first firepower, and the firepower may be set to a second firepower. Alternatively, the ignition switch may be rotated to select a thawing force, a neutralizing force, and a weakening force. In this case, the thawing force may be set to the first thawing force, It can be set to 2 firepower.

As described above, when the gas range starts the ignition operation at the first thermal power, the microprocessor 240 repeats the defrosting operation for the defrosting time t from this time.

The defrosting operation of the microprocessor 240 will be described in detail as follows.

The microprocessor 240 determines whether the temperature of the cooking container 220 sensed by the temperature sensor 230 is lower than the first thawing temperature T1 ) (For example, T-10 占 폚) (S30).

If the temperature of the cooking container 220 sensed by the temperature sensor 230 reaches the first thawing temperature T1 (e.g., T-10 占 폚) in step S30, (S40) whether the temperature of the cooking container 220 is the second defrosting temperature T2 (e.g., T-3 DEG C) at a predetermined first time (e.g., 1 minute).

The interval of the first time (for example, 1 minute) is a preset period for determining whether the temperature of the cooking container 220 is the second defrosting temperature T2 (for example, T-3 ° C) It is preferable to set it automatically corresponding to the defrosting temperature T2 (for example, T-3 占 폚), and it may be set at a predetermined temperature in the gas range production step.

If the temperature of the cooking container 220 detected by the temperature sensor 230 reaches the second defrosting temperature T2 (for example, T-3 ° C) in step S40, Within a predetermined second time (e.g., 5 seconds) after the temperature of the cooking container 220 reaches the second defrosting temperature T2 (e.g., T-3 占 폚) It is determined whether the temperature rises above the defrosting temperature arrival discrimination temperature T3 (for example, 1 占 폚) (S50).

It is preferable that the defrosting temperature arrival discrimination temperature T3 (for example, 1 占 폚) is automatically set in correspondence with the defrosting temperature T or the second defrosting temperature T2 (for example, T-3 占 폚) It may be set at a predetermined temperature in the gas range production step.

The second time (for example, 5 seconds) is a time set in advance to determine whether the temperature of the cooking container 220 rises above the defrosting temperature arrival discrimination temperature T3 (for example, 1 占 폚) It is preferably set automatically corresponding to the arrival discrimination temperature T3 (for example, 1 占 폚), and may be set at a predetermined temperature in the gas range producing step.

If the temperature of the cooking vessel 220 is within the second predetermined time (for example, 5 seconds) after the temperature of the cooking vessel 220 reaches the second defrosting temperature T2 (for example, T-3 ° C) The microprocessor 240 outputs a thermal power reduction signal to adjust the thermal power of the gas range by the second thermal power (for example, 1 < 0 > C) S60).

After the thermal power reduction signal is output as described above (S60), the microprocessor 240 determines whether the temperature of the cooking container 220 is lower than the second defrosting temperature T2 (for example, T-3 占 폚) S70).

If the temperature of the cooking container 220 is less than the second defrosting temperature T2 (for example, T-3 占 폚) in step S70, the microprocessor 240 determines whether the defrosting time t has ended (S80).

If the defrosting time t is not terminated in step S80, the microprocessor 240 returns to step S40 and determines whether or not the defrosting time t has elapsed in the first time interval (e.g., 1 minute) It is determined again whether the temperature is the second defrosting temperature T2 (for example, T-3 占 폚) and the second defrosting temperature T2 (for example, T-3 占 폚) Is not the second defrosting temperature T2 (for example, T-3 ° C) (S40), or the second defrosting temperature T2 (for example, T-3 ° C) If the temperature of the cooking container 220 does not rise above the defrosting temperature arrival discrimination temperature T3 (for example, 1 占 폚) within a predetermined time (for example, 5 seconds) (S50) (S20), and the thawing operation including the steps S30 to S80 is repeated for the defrosting time (t).

When the microprocessor 240 performs the defrosting operation and the defrosting time t is terminated (S80), the microprocessor 240 outputs a defrosting completion signal to the defrosting completion notification unit 250, And the defrosting state of the frozen food is prevented from being deteriorated by automatically extinguishing the gas range (S90).

The present invention is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the scope of the present invention as defined in the appended claims. There is a technical spirit to the extent that anyone who has it can make various changes.
