The present invention relates to an apparatus and method for automatically controlling a thermal power and a burning time of a gas range, and more particularly to an apparatus and method for automatically controlling a thermal power and a burning time of a gas range in which a plurality of memory channels are provided in a data storage unit of a gas range, It is possible to increase the usability and operability of the gas range by automatically controlling the flame by selecting the cooking time and the heating power according to the cooking time corresponding to the food to be cooked after memorizing the required thermal power change data over time, So that they can be heated and cooked in an optimum state.

Generally, a gas range is a heating mechanism using propane gas or butane gas as fuel. In the home gas range, at least one or more burners are provided on the upper surface of a body having a predetermined volume, The number of the gas supply pipes is set between the venturi pipe of the burner and the gas supply pipe so that the opening and closing amount of the knob is determined in response to the amount of rotation of the knob, And a regulating valve is provided.

Therefore, in order to heat or cook unspecified foods using the gas range, first, the knob connected to the burner is operated to operate the speaker, and the valve is opened to ignite the gas. Then, The knob may be appropriately rotated clockwise or counterclockwise to control the opening and closing amount of the gas supply adjusting valve connected to the burner.

In addition, when it is recognized that the cooking of the specific food is completed, the knob connected to the burner is operated to close the gas supply control valve connected to the burner, so that the gas supply is cut off and the fire is extinguished.

The operation and effect of the present invention apparatus and method having the above-described configuration and steps will be described as follows.

First, in the present invention, various keys or switches are installed in the key input unit 1 without installing a knob as in the prior art, so that the automatic and manual mode selection and the setting of the combustion time and the thermal power in each memory channel in the automatic mode As well as ignition and digestion.

3, the key input unit 1 includes a mode selection switch MODE for selecting the memory channels M1 to Mx including the automatic or manual mode, (UP) (DOWN) for setting and selecting a time or firepower, a start key (START) for performing ignition, etc., and digestion And a stop key (STOP) for stopping various functions.

Of course, each of the switches or keys provided in the key input unit 1 can be operated by selecting either a button switch or a touch switch, so that the operation of the key input unit is good and the appearance of the product itself can be kept beautiful.

On the other hand, the flame detecting unit 2 provided on one side of the burner detects the burning or misfiring condition by detecting the temperature of the burner after the ignition or the burning by the dummies, and transmits the detected state to the control unit 3, Time data after digestion including the time required for the combustion operation control of the range is provided to the control unit.

Of course, the control unit 3 performs a predetermined control program based on various data and various input data stored in the data storage unit 6 to automatically or manually control the thermal power and the combustion time of the gas range.

At this time, the data storage unit 6 stores flame state data for each burning time in each memory channel (M1-Mx) including a control program necessary for automatic control of the thermal power of the gas range and the burning time.

On the other hand, the display unit 5 displays various combustion times and error states including the automatic and manual mode operating states under the control of the control unit 3. In the automatic mode, several memory channel display lamps (H, M, L) and a time display unit 51 that display the flame state as "strong", "medium", " Respectively.

At this time, the time display unit 51 displays the set time for each memory channel in the automatic mode, the total burn time in the memory channel, the error state display at the time of the misfire, and the time counted after the digestion.

The sparker driving section 8 under the control of the control section 3 operates the sparker 7 for ignition when the start key START is inputted and the electronic side drive section 10 selects the user selected or selected in the automatic mode Controls the amount of opening and closing of the electronic valve 9 to adjust the gas supply amount in response to the flame condition. The buzzer driving unit 12 drives the alarm buzzer 11 in a misfire state or a fire extinguishing state, .

When the power is supplied, the control unit 3 receives the output signal of the key input unit 1 and detects whether the user selects the automatic or manual mode (S1).

If the manual mode is selected as a result of the detection, the subroutine is executed according to the manual mode.

In this case, the manual mode subroutine S2 performs combustion control in response to a user's key operation. When the start key is normally turned on (S21), ignition is performed (S22) The combustion operation is continuously performed until the input (S30; Yes) (S24).

Of course, if the UP or DOWN key DOWN is inputted by the user during the normal combustion operation (S21-S26) after the ignition in the manual mode (S27: Yes), the current thermal power is increased or decreased S28) The combustion continues to proceed with the flame corresponding to it.

If the result of the detection by the controller 3 indicates that the desired combustion time and thermal power adjustment data are pre-stored in the memory channel of the user among the several memory channels M1-Mx, A subroutine S4 for allowing the user to set and memorize the burning time and thermal power in each memory channel M1-Mx if the data is not stored in the memory channel selected by the user among the memory channels M1-Mx of the memory M1- .

Accordingly, when the user operates one of the mode selection switches MODE of the key input unit 1 to select one of the several memory channels M1-Mx assigned to the data storage unit 6, When the "strong" lamp among the flame state display lamps H, M, L of the display unit 5 is turned on by the control program (S41), the up / down key UP (S42). In this case, the user may set the desired burning time in the reinforcing force by operating the setting switch SET (S42).

When the burning time setting is completed as described above, the "middle" lamp is turned on by the pre-programmed control program (S43). When the "middle" lamp is lit in this manner, (S44). In this case, the time required to set the time is set in the same manner as in the above-described manner.

Of course, when the burning time setting to the neutralization power is completed as described above, the "weak" lamp is turned on this time (S45) and the user sets the time for the combustion to proceed with the weakening power in this state ).

In the above, when the time is set through the UP / DOWN key (DOWN), the time is normally up or down in units of 5 seconds or 10 seconds to set the maintenance time of the fire to "strong", "medium" So that the up / down change time is not limited to the above embodiment.

When the setting of the burning time for each firepower in one of the memory channels is completed in the above procedure, the control unit 3 causes the user to select another memory channel by UP / DOWN (UP) (S47). As a result, if another memory channel is selected through the UP / DOWN key, the "strong" lamp is turned on as described above (S48) It is possible to continuously input thermal power adjustment data for each time period into the memory channel again selected by returning to step S42.

On the other hand, when the control unit 3 detects data input to the data storage unit 6 as a result of the detection, if the desired combustion time and thermal power adjustment data are stored in the memory channel (S3: Yes) (S5).

When the user selects a desired memory channel and turns on the start key (S6) by operating the sparker driving unit 8, the sparker is operated to perform ignition (S7) (9) of the burner is opened to automatically adjust the thermal power to "strong", "medium", "weak" for each time stored in the memory channel (S9).

When the predetermined time has elapsed (S12; Yes) by automatically adjusting the firepower to "strong", "medium", "weak" according to the time zone stored in the memory channel, the electronic valve 9 is closed, (S13).

In addition, as described above, when the fire power is automatically adjusted to "strong", "medium", "weak" for each time stored in the memory channel in the automatic mode and the combustion is performed for a predetermined period of time (S9-S13) The control unit 3 checks the time elapsed from the time of extinguishing by using the timer 4 and displays it on the display unit 5 at step S14 so that when the user returns to the gas- I can clearly recognize what time it has been done before and take the necessary action.

The post-extinguishing time counter continues until the stop key is input (S15; Yes) by the user.

If the ignition operation is performed in the automatic or manual mode (S7, S22), the control unit 3 detects whether the flame is detected within a predetermined time (i.e., several seconds) through the flame detection unit 2, (S11, S26, S29; Yes), the electronic valve is closed and disappeared, and the display portion 5 and the buzzer 11 are closed It is possible for the user to recognize the unfired state or the misfire state through visual and auditory sense and to take necessary measures in a short time.

Of course, when the stop key STOP is inputted by the user during the combustion operation in the automatic mode as described above (S10: Yes), the electronic valve 9 is operated regardless of the remaining time during the time that is stored in the memory channel Closed and forced to be digested.

It should be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention.

 As described above, according to the present invention, first, a plurality of memory channels are provided in the data storage unit of the gas range, and thermal power variation data for each time period required for cooking and cooking unspecified foods in an optimal state are stored It is possible to improve the usability and operability of the gas range by controlling the flame to be automatically controlled by selecting the cooking time and the heating power according to the cooking time to be cooked, as well as heating and cooking the food in an optimal state .
