Description of the Related Art A cooking apparatus including a combustion controller for controlling the combustion amount of a gas burner so that the detection temperature becomes a set temperature, and a buzzer that operates when the detection temperature reaches a set temperature.

In the above conventional cooking apparatus, the combustion amount control based on the temperature is started so that the buzzer sounds only the first time when the detection temperature reaches the set temperature. This means that the buzzer will always sound when the detection temperature reaches the set temperature. For example, in the case of cooking such as frying, the temperature of the frying oil will be set whenever the cooked product is introduced into the cooking vessel. Since the buzzer is slightly lowered, and the buzzer is operated every time the detection temperature returns to the set temperature again, the use of the cooking vessel becomes inconvenient due to the confusion caused by the frequent buzzer of the buzzer.

In the conventional cooking apparatus, when the set temperature is changed during cooking after the detection temperature reaches the set temperature and the buzzer is operated, the buzzer does not operate even if the detected temperature is changed to the changed set temperature. The user who stops cooking until it does not know when to resume the cooking is a disadvantage that the use of the cooking vessel is inconvenient.

An object of the present invention is to provide a cooking apparatus having an alarm means for sounding an alarm when the detection temperature reaches a set temperature in order to improve the convenience of use.

When the temperature setting means was re-operated after the alarm sounded by, the alarm means sounds an alarm sound again when the detection temperature reaches the newly set set temperature.

The combustion controller controls the heating by the heating source such that the detected temperature detected by the temperature sensor arranged to contact the cooking vessel containing the cooked object is a temperature set by the temperature setting means.

The alarm means sounds an alarm when the detected temperature reaches the set temperature. When the temperature setting means is re-operated after this alarm, the alarm means sounds the alarm again when the detected temperature reaches the newly set set temperature. Sounds.

Therefore, according to the present invention, when the detection temperature reaches the set temperature, an alarm sounds, and when the temperature setting means is re-operated after this alarm, the alarm means is restarted when the detection temperature reaches the newly set temperature. This beeps. Therefore, the user can easily grasp when the detection temperature reaches the newly set set temperature, that is, when the cooking can be resumed, and can cook with confidence. Convenience is improved.

The height is provided with the "+" key 32. Each said key 31 and 32 is arrange | positioned at the surface of the plastic operation panel 30 formed in the front left of the gas table A, and is electrically connected with the control unit 4. As shown in FIG. Moreover, the 7-segment green LED 33 which digitally displays a set temperature etc. is also arrange | positioned at the operation panel 30. As shown in FIG.

When the gas table A is first used, that is, when the power is turned on, the set temperature is automatically set to 180 deg. C, and after the second use, the previous set temperature is automatically set to the set temperature.

The control unit 4 is equipped with a microcomputer and compares the setting signal of the temperature setting means 3 with the electrical output of the temperature sensor 2, and in the case of the frying cooking mode which performs temperature regulation control as a general rule, [ The combustion of the M burner 13 is controlled by opening and closing the temperature regulating solenoid valve 03 so that the detection temperature = set temperature ± 4 ° C. In addition, when changing the set temperature set by the temperature setting means 3, the microcomputer of the control unit 4 is based on M based on the set temperature before the change until 1 second has elapsed from the completion of the operation for changing the set temperature. After the combustion of the burner 13 is controlled, and after one second has elapsed, the combustion of the M burner 13 is controlled based on the changed new set temperature, and the buzzer is detected when the detected temperature reaches the new set temperature. Activate (5).

As described above, the operation of the buzzer 5 is limited to only the first one as a rule, in order to prevent confusion caused by the frequent alarm sound of the buzzer during the temperature control control combustion. Temperature-predetermined temperature (for example, -30 ° C)], it is assumed that a large amount of frying oil in frying cooking, etc. is added, and it informs the time when the cooking which was stopped can be resumed, and the convenience of use To improve, it is activated when the detection temperature reaches the set temperature again.

Further, after the frying cooking mode is selected, the operation of the buzzer 5 and the switching to the small thermal power of the solenoid valve 103 for temperature adjustment are performed at the time when the detected temperature reaches the set temperature for the first time, but the ignition / fire extinguishing button 16 is executed. During the five seconds after the switch 16a is turned on and the M burner 13 starts combustion, it is necessary to burn with [forced fire power] forcibly burning with a large fire power to improve the ignition performance. Therefore, the operation of the burner 5 and the switching to a small thermal power are not executed during the above 5 seconds even if the detection temperature reaches the set temperature.

The right furnace 6 is placed on the right side as shown in FIG. 1, and the thermocouple 63 which generates electromotive force by the ignition electrode 62 and the combustion flame 60 is formed by the H burner 61.

It is arrange | positioned close toward the porous combustion plate of the grill burner 71. Moreover, 701 and 702 are a safety valve and a main valve arrange | positioned in the middle of the gas pipeline 703.

Next, an example of the operation of the control unit 4 with a microcomputer will be described with reference to FIG. 3 and FIG.

When the user turns on the power switch of the gas table A, the set temperature is automatically set to 180 ° C. Then, press the "+" key 32 of the operation panel 30 once (elapsed time to) to change the set temperature from 180 ° C to 190 ° C, and then press the frying-cooking mode key 34 to ignite and extinguish it. When the button 16 is pressed, the safety valve 101 and the main valve 106 interlock with each other to open the valve, and the switch 16a is turned on, and the control unit 4 is designated as the safety valve 101. By keeping the valve open while energizing for time, the solenoid valve 103 for temperature adjustment is brought into the valve open state, and energized by the ignition electrode 14, so that the left furnace 1 is ignited to start combustion with a large fire power.

At the time elapsed time t ₁ , when the detected temperature reaches 190 ° C., which is the set temperature, the control unit 4 operates the buzzer and stops supplying power to the temperature regulating solenoid valve 103 so as to stop the [temperature regulating solenoid valve. (103) Closed] The thermal power of the M burner 13 is switched to a small thermal power. The control unit 4 opens and closes the solenoid valve 103 for temperature control so that [detection temperature = 190 degreeC +/- 4 degreeC] (first time detection temperature = 190 degreeC), and repeats alternately with large thermal power-small thermal power. Control combustion of (13).

That is, when the detection temperature reaches 186 ° C (190 ° C-4 ° C) at the time elapsed time t ₂ , the control unit 4 resumes energization with the temperature control solenoid valve 103 and the [temperature control solenoid valve ( 103 is opened] When the thermal power of the M burner 13 is set to a large thermal power and the detection temperature reaches 194 ° C (190 ° C + 4 ° C) at the time of elapsed time t ₃ , the control unit 4 is used for temperature control. The energization to the solenoid valve 103 is stopped (close the temperature regulating solenoid valve 103), and the thermal power of the M burner 13 is switched to small thermal power. In addition, when repeatedly controlling with the large thermal power-small thermal power, the buzzer 5 is not operated when the detection temperature reaches the set temperature of 190 ° C, so that the user is confused by the frequent alarm sound of the buzzer 5. It does not cause it.

Here, in FIG. 4, at step S1, the step S2 corresponds to the elapsed time (t ₁₎ ~ elapsed time (T ₄₎ to the temperature control in the combustion [Setting temperature 190 ℃ ± 4 ℃].

At the time of elapsed time T ₄ , the user starts pressing the "-" key 31, and at the time elapsed time t ₅ at which _five pressing operations have ended (equivalent to Yes in step S3), the green LED ( 33) denotes "140 ° C" which means 140 ° C.

At the elapsed time t ₆ , which is 1 second (Yes in step S4) from the last pressing operation (the fifth time) of the "-" key 31, the set temperature is sent to the control unit 4, so the set temperature is 140 degrees. change to ℃ and in the subsequent (step S5), the elapsed time (t _6), such that the [detected temperature = 140 ℃ ± 4 ℃] the (first detects temperature = 140 ℃) controlling the combustion of the M burner 13 . 3, the thermal power of the M burner 13 from the elapsed time t ₆ to the elapsed time t ₇ is small.

When the elapsed time t ₇ reaches [detection temperature = 140 ° C.] (Yes in step S6), the control unit 4 operates the buzzer 5 (step S7), and at the same time, the solenoid valve 103 for temperature control. [Opens the temperature regulating solenoid valve 103] to switch the thermal power of the M burner 13 to a large thermal power.

In addition, between the elapsed time t ₆ and just before the elapsed time t ₇ , the buzzer 5 is not operated because the detection temperature does not fall to the set temperature.

Thereafter, the flow returns to step S2, and as described above, the large thermal power-small thermal power is repeatedly burned so that the detection temperature becomes [140 ° C +/- 4 ° C]. Also at this time, even if the detection temperature reaches 140 ° C, the buzzer 5 does not operate.

Next, another example of the operation of the control unit 4 with the microcomputer will be described based on FIG. 5 and FIG.

[In case of FIG. 5]

For 5 seconds from the elapsed time point 831 (0 second) from the start of combustion to the elapsed time 834, the M burner 13 is burned with a large thermal power to raise the electromotive force of the thermocouple 15 early. Forced firepower is implemented to improve the ignition performance. In the elapsed time (832), by pressing the fried food mode key 34 to switch the M burner 13 to the fried food mode to control the temperature, the set temperature at this time is set to 190 ° C set in the previous cooking mode. Then, even if the detected temperature reaches 190 ° C, which is the set temperature, in the elapsed time 833 in the range within the above 5 seconds, the operation of the buzzer 5 and switching to a small thermal power by the solenoid valve 103 for temperature control The operation of the buzzer 5 and the switching to a small fire power are executed at the time when the "forced fire power" ends (elapsed time 834) without executing.

This is for ensuring the improvement of the said ignition performance by prior combustion with [forced fire power].

[In case of FIG. 6]

In the elapsed time 841, when the user presses the fried food mode key 34 to switch the M burner 13 to the fried food mode in which the temperature is controlled by the boiling food mode key, the set temperature at this time is the last boil. It is set to 190 ° C set in the cooking mode. Subsequently, while thinking that what should be the set temperature should be, press the "+" key 32 and the "-" key 31 alternately (two times each) to finally set the set temperature at 190 ° C in the elapsed time (843). When the detection temperature reaches 194 ° C (190 ° C + 4 ° C), the energization to the temperature control solenoid valve 103 is stopped (close the temperature control solenoid valve 103) and M The thermal power of the burner 13 is switched to a small thermal power, but the buzzer 5 is not operated because the temperature is being set.

At an elapsed time 844 that elapses one second from the elapsed time 843, the microcomputer recognizes the set temperature as 190 DEG C, and since the detection temperature at this point has reached 190 DEG C or lower, the thermal power of the M burner 13 is reduced. Switch to big firepower.

When the detected temperature reaches 190 ° C, which is the set temperature at the elapsed time 845, the thermal power of the M burner 13 is switched to a small thermal power, and the buzzer 5 is operated.

[In case of FIG. 7]

Since the state of the contact is detected every predetermined time, the "-" key 31 or " + " Then, at the elapsed time 852 one second has elapsed from the time point (elapsed time 851) when the set temperature displayed on the green LED 33 reaches the upper limit temperature (220 ° C) or the lower limit temperature (130 ° C), the set temperature is It is settled at 220 degreeC or 130 degreeC. 7 shows a case where the set temperature is changed from 190 ° C. to 220 ° C. by continuously pressing the “+” key 32.

Hereinafter, the gas table A of the present embodiment has the following advantages.

(a) When the detected temperature reaches the set temperature (eg 190 ° C), the buzzer 5 is operated. Then, when the set temperature is changed (190 ° C to 140 ° C), the detected temperature reaches the changed set temperature. When the buzzer 5 is operated again. Therefore, the user can confirm that the detection temperature has reached the changed set temperature at the time when the alarm sound of the buzzer 5 is heard, and the cooking that has been interrupted can be resumed, so that the user can cook with confidence and convenience of use. This is improved.

(b) The set temperature is determined at the time point 1 second elapses after the "-" key 31 and the "+" key 32 are released. Therefore, it is possible to prevent the drawback that the fire power of the M burner 13 is switched every time the buzzer 5 is operated or the "-" key 31 and the "+" key 32 are operated during the operation of the key.

(c) Normally, when the detected temperature reaches the set temperature (first time), the buzzer 5 is operated. However, as shown in FIG. 5, at a time elapsed within 5 seconds from the start of combustion (elapsed time 831). When the detected temperature reaches the set temperature (elapsed time 833), it switches to a smaller thermal power at the end (elapsed time 834) of the [forced thermal power] period (time required to secure the ignition performance) for 5 seconds. The buzzer 5 is operating.

(d) Normally, the set temperature is determined at the point of 1 second after the pressing operation of the "-" key 31 and the "+" key 32 is released, but as shown in FIG. For example, when the " + " key 32 is kept pressed, the set temperature is determined after one second has passed (elapsed time 852) from the time point at which the display of the set temperature reached the 220 ° C upper limit temperature (elapsed time 851). For example, 220 ° C., even if the key is kept pressed, the buzzer 5 is operated when the detected temperature reaches the set temperature (elapsed time 853). Even in the case of a special key operation, the buzzer 5 Alarm function is not impaired.
