At the same time, two seven-segment LEDs 102 are provided for displaying the remaining time of heating cooking during timer cooking.

Thus, by providing the plus key switch 100, the minuskey switch 101, and the 7 segment LED 102, the user can subdivide the execution time of the dimer cooking, for example, by 1 minute unit, and heat The remaining time of cooking can be detailed. However, while the seven segment LED 102 is relatively expensive, the number of output points of the interface required for controlling the display content is also large. Therefore, there is a problem in that the cost increase of the gas table is increased due to the seven segment LED 102.

In addition, in the table range, 8 (minutes) is displayed on the 7 segment LED 102 as an initial value of the execution time of timer cooking when the grill burner is ignited, so that the user can use the plus key switch 100 or the minuskey switch 101. It is a aspect to set the execution time of the desired timer cooking by operating. In this case, for example, when the execution time of timer cooking is set to 3 minutes, the user has to press the minuskey switch 101 five times.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and provides a heating cooker having a timer device that reduces the cost of the means for displaying the execution time of the timer cooking and facilitates the setting of the execution time of the timer cooking. There is a purpose.

Thus, the heating cooking apparatus of the present invention for achieving the above object is a cooking time setting switch for setting the running time of the heating cooking by the heating means, a cooking timer for performing the subtraction counting with this running time as an initial value, and this cooking Remaining time display means for displaying the remaining time of the heating cooking in correspondence with the time of the timer, and from the start of the time by the cooking timer until the time of the cooking timer becomes zero In the meantime, the present invention relates to an improvement in a heating cooker having a timer device that operates the heating means to execute a timer cooking operation for stopping the heating means when the time limit of the cooking timer becomes zero.

The cooking time setting switch sets the execution time of heating cooking to any one of a plurality of predetermined selection times, and the remaining time display means includes a single lamp which is individually set corresponding to each of the selection times, and the cooking time setting switch. Is operated, the lamp is turned on or flashes corresponding to the selection time set by the operation, and when the cooking time timer reaches each selection time, the corresponding lamp reaches the selected time during execution of the timer cooking operation. And lighting control means for lighting or blinking the single lamp corresponding to the selection time.

In addition, according to the present invention, the execution time of the timer cooking operation is set to any one of the predetermined plurality of selection times, and the selected execution time and the remaining time of the timer cooking operation are individually set corresponding to the plurality of selection times. It is indicated by the single lamp.

Therefore, for example, when the selection time is set in four stages, the four lamps may be used at a relatively low cost, and the cost of the remaining time display means may be reduced compared with the case of using expensive seven-segment LEDs. Can be saved. Further, by setting the plurality of selection times with a certain width, even when a change width of the execution time of the timer cooking operation is relatively large, the number of times of operation of the cooking time setting switch required is reduced to execute the timer cooking operation. You can easily change the time.

In addition, when the cooking time setting switch is operated during the execution of the timer cooking operation, a timer cooking time for starting a clock by the cooking timer with a new execution time set by the operation as an initial value. Characterized in that the change means.

Further, according to the present invention, it is possible to easily change the execution time of the timer cooking operation in the plurality of selected time units during the execution of the timer cooking operation.

In addition, a mode switching switch for switching between a fire extinguishing prevention timer for initializing a predetermined upper limit time and performing a subtraction clock at the start of operation of the heating means, a timer cooking mode for executing the timer cooking operation, and the fire extinguishing prevention timer. And the lighting control means turns on or flashes the light lamp corresponding to the attainment selection time when the time limit of the extinguishment forgetting timer reaches each selection time in the indigestion prevention cooking mode. And a mode switching prohibiting means for prohibiting the switching to the fire extinguishing prevention cooking mode by the mode switching switch when the time limit of the fire extinguishing prevention timer in the timer cooking mode becomes less than the longest time of the selection time. It is characterized by one.

According to the present invention, when the mode switching switch is switched from the timer cooking mode to the fire extinguishing prevention cooking mode, the remaining time until the operation stop of the heating means displayed on the lighting lamp by the lighting control means. A subject is switched from the cooking time timer to the fire extinguishing timer. Therefore, when the time for the extinction forget-memory timer is switched to the extinguishing forget-measuring mode from the timer cooking mode when the time limit is less than or equal to the longest time of the selection time, the remaining time indicated by the light lamp suddenly increases ( The time of cooking time <for the time of the anti-digestion timer for fire extinguishing) or decreases (for the time of the cooking time> the time for the fire extinguishing timer) for the user to give a sense of discomfort.

Here, in the timer cooking mode, in the timer cooking mode, when the timeout of the fire extinguishing timer is less than the longest time of the selection time, the mode switching prohibition means causes the fire extinguishing prevention cooking mode by the mode switching switch. Prohibited switching to In addition, it is possible to prevent the remaining time until the stop of the heating means, which is displayed, increases and decreases rapidly, thereby making the user feel uncomfortable.

The timer time display unit 20 (1 minute LED 21, 3 minute LED 22, 6 minute LED 23, 9 minute LED 24) for setting the execution time of the timer cooking operation and remaining time is displayed. Each LED corresponds to a single lamp of the present invention, and a release LED 25 that lights when the timer cooking operation is in a released state.

Next, with reference to FIG. 2, the grill 3 is the grill 30 which puts food F, such as fish, in the inside, and the combustion surface is lowered in the ceiling of the grill 30. An upper burner 31 facing (corresponding to the heating means of the present invention) is provided, and a lower burner 32 in which salt balls are directed in the lower side of the side walls on both sides of the grill 30 (this invention) Equivalent to a heating means). The upper burner 31 is connected to the upper burner gas supply pipe 34 branched from the main gas supply pipe 33, and the lower burner 32 is connected to the lower burner gas supply pipe 35.

In addition, a left range burner 36 is provided on the left range 2, and a left range gas supply line 37 branched from the main gas supply line 33 is connected. In addition, the right range burner 38 is provided in the left range 1, and the right range gas supply pipe 39 branched from the main gas supply pipe 33 is connected.

On the upstream side of the branch point from the main gas supply pipe 33 to the upper burner gas supply pipe 34 and the lower burner gas supply pipe 35, the supply / blocking of fuel gas corresponding to the upper burner 31 and the lower burner 32 is stopped. A solenoid valve 40 for switching is provided. In addition, the upper burner gas supply pipe 34 is provided with a thermal control valve (not shown) whose mechanical opening is changed by the thermal control knob 12 (see FIG. 1A), and the lower burner gas supply pipe. 35 is provided with a thermal control valve (not shown) whose mechanical opening degree is changed by the thermal control knob 13 (see FIG. 1A).

In addition, the left range gas supply pipe 37 is mechanically operated by a solenoid valve 41 for switching the supply / discharge of fuel gas corresponding to the left range burner 36, and a thermal power control knob 11 (see FIG. 1A). As a result, a thermal control valve (not shown) having a variable opening degree is installed. In addition, the right range gas supply pipe 39 is mechanically operated by the solenoid valve 42 and the thermal power control knob 10 (see FIG. 1A) for switching supply / discharge of fuel gas corresponding to the right range burner 38. A thermal control valve (not shown) having a variable opening degree is installed.

In addition, the upper burner 31, the lower burner 32, the left range burner 36 and the right range burner 38 respectively detect the ignition electrodes 43, 44, 45 and 46 and the combustion state of each burner. Thermocouples 47, 48, 49 and 50 are provided. In addition, the right range 1 is provided with a temperature sensor 51 for detecting the temperature of the bottom of the cooking vessel P1, and for the right range 31, the right range burner based on the detected temperature of the temperature sensor 51. Temperature cooking to control the thermal power of (38) is executed.

The gas table A is equipped with the controller 60 which controls the combustion operation of the right side stove 1, the left side stove 2, and the grille 3. As shown in FIG. The controller 60 is an electronic unit composed of a microcomputer and a memory, and combustion control means 61 and cooking timer 62 for controlling the combustion operation of the left and right stoves 1 and 2 and the grill 3. And a fire extinguishing prevention timer 63, a lighting control means 64, a mode switching prohibition means 65, and a timer cooking time changing means 66.

The cooking timer 62 performs the subtraction time measurement with the execution time of timer cooking set by the operation of the grill switch 19 as an initial value. In addition, the fire extinguishing prevention timer 63 performs the subtraction measurement by setting the predetermined upper limit time as an initial value when the ignition of the upper burner 31 and the lower burner 32 is detected. Here, in the heating cooker of the present embodiment, both sides of the upper burner 31 and the lower burner 32 are burned during the combustion operation of the grill 3, and the upper limit time (initial value) of the fire extinguishing timer 63 is performed. ), For example, 15 minutes. That is, in a heating cooker equipped with a grill for one-side combustion in one of the upper burner and the lower burner, the upper limit time (initial value) of the fire extinguishing timer 63 is longer than that for double-sided combustion (for example, 21 minutes). Is set.

The combustion control means 61 controls the combustion operation of the upper burner 31 and the lower burner 32 by switching the operation mode of the grill 3 to the "timer cooking mode" and the "digestion forgetting cooking mode". In the timer cooking mode, "timer cooking operation" in which the solenoid valve 40 is closed and the combustion of the upper burner 31 and the lower burner 32 is stopped when the clocking time C_cnt of the cooking timer 62 becomes zero. Run

In addition, in the fire extinguishing prevention cooking mode, the combustion control means 61 closes the solenoid valve 40 when the time-out time F_cnt of the fire extinguishing prevention timer 63 becomes zero, and the upper burner 31 and the downward direction. A fire extinguishing prevention cooking operation which stops combustion of the burner 32 is performed. As a result, when the user forgets the extinguishing operation of the grill 3, the combustion of the upper burner 31 and the lower burner 32 is forcibly stopped.

Next, the case of double-sided grilling which operates the upper burner 31 and the lower burner 32 simultaneously with respect to the execution procedure of the timer cooking operation by the grill 3 is demonstrated as an example. When the user operates the ignition / fire extinguishing switch 6 (see FIG. 1A) of the grill 3 to instruct the ignition of the grill 3, the combustion control means 61 applies a high voltage to the ignition electrodes 43 and 44. Then, the solenoid valve 40 is opened in the state of a fire discharge, and the upper burner 31 and the lower burner 32 are ignited.

When the ignition of the upper burner 31 and the lower burner 32 is detected by the outputs of the thermocouples 47 and 48, the fire extinguishing timer 63 starts the subtractive time with 15 minutes as the initial setting. That is, in a heating cooker equipped with a grill for one-side combustion in one direction of the upper burner and the lower burner, the fire extinguishing timer is set to 21 minutes (for a longer time than in the case of double-sided combustion) and the subtractive time is set. It starts. In addition, as the initial setting, 9 minutes is set as the initial setting in the "timer cooking mode", and the subtraction time measurement by the cooking timer 62 is started. At this time, the lighting control means 64 turns on the LED 24 for 9 minutes, whereby the upper burner 31 and the lower burner 32 are ignited, and the execution time of the timer cooking operation is set to 9 minutes. Inform.

3 and 4 are flowcharts showing the procedure of changing the execution time of the timer cooking operation after the ignition of the upper burner 31 and the lower burner 32 is detected, and the lighting control means 64 firstly steps (STEP). As described above in step 1), the 9 minute LED 24 is turned on, and then, in step 3, the cooking timer 2 starts the subtraction counting with 9 minutes as the initial value. In the initial setting, the timer is set to "timer cooking mode", and the combustion control means 61 continues to burn the upper burner 31 and the lower burner 32 until the time limit of the cooking timer 62 becomes zero. When the clock time reaches zero, execution of the "timer cooking operation" for stopping the combustion of the upper burner 31 and the lower burner 32 is started.

The following steps 4 and 5 are the processing by the mode switching prohibiting means 65, and the mode switching prohibiting means 65 determines whether or not the time-out of the fire extinguishing prevention timer 63 is 9 minutes or less in step 4; do. When the time delay of the fire extinguishing prevention timer 63 exceeds 9 minutes, the flow proceeds to step 5, and the combustion control means 61 changes the operation mode of the grill 3 from the "timer cooking mode" to "digestion forgetting prevention". Cooking mode ”. On the other hand, in step 4, when the time-out of the fire extinguishing timer 63 is 9 minutes or less, the flow branches to step 7 to maintain the "timer cooking mode".

Specifically, the mode switching prohibiting means 65 instructs the combustion control means 61 to allow or prohibit switching to the "digestion forgetting cooking mode" by switching the mode switching plug m_chg ON / OFF.

Here, in the fire extinguishing prevention mode, as shown in Fig. 5 (a), when 15 minutes have elapsed from the ignition time t ₀ of the upper burner 31 and the lower burner 32 (t ₅ ). The combustion control means 61 stops the combustion of the upper burner 31 and the lower burner 32.

Then, the lighting control means 64 performs "cooking remaining time display" informing the user of the remaining time until the end of heating cooking by the grill 3. Specifically, the lighting control means 64 is a 9 minute LED 24, 6 minutes LED 23, when the time to time the fire extinguishing timer 63 is 9 minutes, 6 minutes, 3 minutes, 1 minute The 3 minute LED 22 and the 1 minute LED 21 are sequentially lighted ("9 minute LED 24 lights"-> "6 minute LED 23 lights"-> "3 minutes LED 22 lights") -> "1 minute LED (21) lit").

Then, the lighting control means 64 flashes the LED 21 at the same time when the time delay of the fire extinguishing prevention timer 63 reaches 30 seconds and at the same time sounds a buzzer (not shown), and the fire extinguishing prevention timer 63 When the time becomes 0 seconds, all LEDs of the time display unit 20 light up and at the same time buzzer sounds.

Also in the "timer cooking mode", the lighting control means 64 has a 9 minute LED 24 and a 6 minute LED when the cooking time of the cooking timer 62 reaches 9 minutes, 6 minutes, 3 minutes, and 1 minute. (23), the 3 minute LED 22 and the 1 minute LED 21 are sequentially lighted. When the time limit of the cooking timer 62 reaches 30 seconds, the lighting control unit 64 blinks the LED 21 at the same time and sounds a buzzer (not shown), and the time of the cooking timer 62 is zero. When the seconds are reached, all the LEDs of the time display unit 20 light up and at the same time buzzer.

In this case, as shown in FIG. 5 (b), when the time for the extinction forget-memory timer 63 becomes less than 9 minutes or less (before t ₂ ), the “digestion forgetting prevention mode” in the “timer cooking mode” There is no problem even if you switch to ". However, as shown in Fig. 5 (c), after the time limit of the fire extinguishing timer 63 becomes 9 minutes or less (t ₂ or less), the timer cooking mode is switched to the fire extinguishing prevention mode. At one time, the lighting display of the cooking remaining time is unnatural in the time display section 20.

For example, when the cooking time of the cooking timer 62 is 1 minute in the "timer cooking mode" and the minute 21 is lit, the time is changed from the "timer cooking mode" to the "digestion forgetting cooking mode". (t ₃ ), when the time for the extinction forget-time timer 63 is 7 minutes, the 1 minute LED 21 is turned off and the 9 minute LED 24 is turned on. In this case, irrespective of whether the user performs an operation of releasing the "timer cooking mode", the result is the same as the operation of changing the execution time of the timer cooking operation, resulting in discomfort to the user.

In this case, when the time-out of the extinguishing forget-time timer 63 becomes 9 minutes or less in step 4, the above-described time display unit 20 branches to step 7 to prohibit switching to the "digestion-preventing cooking mode". This prevents the display of an unnatural time.

Steps 6 to 4 are processing for changing the execution time of timer cooking. When the grille switch 19 is operated in step 6, the process proceeds to step 7 where the 1 minute LED 21 is controlled by the lighting control means 64. In step 8, the timer cooking time changing means 66 starts the subtraction time measurement by the cooking timer 62 with 1 minute as the initial value.

In addition, when the grille switch 19 is operated in step 9 of FIG. 4, it progresses to step 10 and the 3 minute LED 22 by the lighting control means 64 is lighted, and the timer cooking time changing means in step 11 is performed. (66) starts subtraction time measurement by the cooking timer 62 with 3 minutes as the initial value. In addition, when the grille switch 19 is operated in step 12, it progresses to step 13, the 6 minute LED 23 is lighted by the lighting control means 64, and in step 14, the timer cooking time changing means 66 is 6 The subtraction time measurement by the cooking timer 62 is started with the minute as an initial value. When the grille switch 19 is operated in the next step 15, the process returns to step 1 in FIG.

3 and 4, the grill switch 19 is operated when the time limit of the extinguishment forgetting timer 63 exceeds 9 minutes. In the time display section 20, the grill switch 19 is operated. LED to be lit is "9 minutes LED (24)"-> "Time display part (All LEDs off 200 (Switch from timer cooking mode to fire extinguishing prevention mode, release LED (25) lights)"-> "1 minute LED (21) "->" 3 minutes LED (22) "->" 6 minutes LED (23) "->…, and so on.

Subsequent to the subtraction measurement of the cooking timer 62 is started with the time corresponding to the LED to be lit as an initial value. Therefore, the user can change the execution time (C_tm in Fig. 2) of timer cooking by simple operation of one switch called grill switch 19. FIG.

In addition, when the time-out time of the fire extinguishing prevention timer 63 is 9 minutes or less, by operating the grille switch 19, the LED which is lighted on the time display part 20 is "9 minute LED 24"-> "1 minute LED". (21) "->" 3 minutes LED (22) "->" 6 minutes LED (23) "->. It is forbidden to switch to the "fire extinguishing prevention cooking mode" by switching to the.

Therefore, it is possible to prevent the occurrence of unnatural display in the above-described time display section 20, and to easily change the execution time of timer cooking. In this case, in addition to the grill switch 19, it is not necessary to separately install a switch for switching the operation mode of the grill, so that the cost of the operation panel 14 and the installation space of the switch can be reduced.

In addition, using a single LED (1 minute LED 21, 3 minute LED 22, 6 minute LED 23, 9 minute LED 24), the setting time of the timer cooking operation, the timer cooking operation and the &quot; In the fire extinguishing prevention mode ", the display with the remaining time of cooking can reduce the cost compared to displaying these times using the 7-segment LED.

In other words, the set time of the timer cooking operation and the remaining time of cooking in the timer cooking operation and the `` digestion forgetting mode '' may be distinguished by differentiating the light emission color of the single lamp, or lighting (continuous light emission) and blinking ( Parallax light emission).

In addition, although the example which applied this invention to the table stove A was shown as the heating cooker of this invention in the form of this embodiment, the application target of this invention is not limited to this, Other types of gas cookers, such as a gas oven, are shown. And the present invention can also be applied to an electric cooker.

As described above, the heat cooker of the present invention has the effect of reducing the cost of the means for displaying the execution time of the timer cooking and facilitating the setting of the execution time of the timer cooking.
