Further, since the timing start signal is automatically generated, the setting work can be facilitated.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 to 7 are block diagrams showing the configuration of each embodiment of the electric cooking heater of the present invention. In FIG. 1, 1 is a heating cooking container such as a kettle or a pot, 2 is heating means for heating the heating cooking container 1 (hereinafter referred to as a heater), 3 is heating control means for controlling the heater 2, and 4 is heating control.

Reference numeral 7 denotes an input end detector that determines that the input operation has been completed if the input section 6 has not been operated for a certain period of time and outputs a timing permission signal to the heating control means 3.

Further, in FIG. 3, 8 is a heater control section for controlling the energization of the heater 2, 9 is a timer means, and this timer means 9 receives the input of the amount of time from the time input means 5.
The heater control unit 8 outputs a timing end signal to the heater 2

Further, in FIG. 4, reference numeral 12 is a time counting prohibiting device for outputting a reset signal to the timer means 9 by setting the heating input means 4.

Further, in FIG. 5, 13 is a second timer means,
The second timer means 13 starts timing when the heating input means 4 receives a heating setting input, and outputs a heating stop signal to the heater control section 8 when the heating input means 4 performs timing for a predetermined time. It is controlled by means 9.

Further, in FIG. 6, 14 is a temperature detecting means for detecting the temperature of the cooking container 1 heated by the heater 2, and 15
Is an arrival detecting means for detecting that the detected temperature input to the heater control unit 8 has reached a set value set by the heating setting input.

Further, in FIG. 7, 16 is a third timer means,
The third timer means 16 stops the time counting operation by the arrival detection of the arrival detection means 15, and if there is no arrival detection, measures the predetermined time and then outputs the energization stop signal of the heater 2 to the heater control section 8. Is a timer means.

 Next, the operation of the present embodiment having the above configuration will be described.

First, the user inputs the heating input means 4 when cooking.
Set and input the output of heater 2. For example, when cooking boiled eggs, the high output setting is first input. As a result, the heating control means 3 sets the output of the heater 2 so that the output is the highest, and energizes the heater 2 to heat the cooking vessel 1. At the same time, the user inputs the heating time from the time counting input means 5. For example, if heating is performed for 5 minutes, input 5 minutes. However, the setting of 5 minutes input here is the cooking time after the water in the heating and cooking container 1 boils. When the setting from the heating input means 4 is high output, the heating control means 3 does not measure the time, but when the setting from the heating input means 4 is low output, the heating control means 3 is started. Therefore, the heating control means 3 receives the input from the time measurement input means 5 and measures the time for 5 minutes,
Since the setting from the heating input means 4 is a high output, the above timing is not started. This state continues until the water in the cooking vessel 1 boils.

Next, when the water in the heating and cooking container 1 boils, the user reduces the heating power of the heater 2, so that the user inputs a low output setting to the heating input means 4. As a result, the heating control means 3 controls the output of the heater 2 so as to reduce it. At the same time, since the heating control means 3 is configured to measure the time when the setting from the heating input means 4 is low, the time control for the 5 minutes set by the time input means 5 is started, and When this timing is completed, the heating of the heater 2 is stopped. That is, the eggs in the heating cooking container 1 are
After boiling the water, it is boiled for 5 minutes to form boiled eggs.

According to the present embodiment, if the cooking settings are collectively input at the start of cooking, then the timer automatically operates by adjusting the heating level according to the cooking quality. It is possible to reduce the troublesome setting.

Further, in the embodiment of FIG. 2, when the input of the time setting is finished, the input end detector 7 detects that there is no input, and outputs the time permission signal to the heating control means 3 to control the heating. Since the means 3 starts timing, the user does not need to input the start of the timer, and as a result, the input operation is simplified and the input switch for that is not necessary, so that the configuration can be made at a low cost. There is an advantage.

In addition, the heating control means 3 of the configuration of FIG. 1 starts the timing set by the timing input means 5 when the heating input means 4 has a heating setting input, whereby the start signal of the timing is heated. Since it is automatically generated by the input of the input means 4, the user does not need to input the start of the timer at the time of inputting the setting of the timekeeping input means 5, and as a result, the input operation is simplified and the input switch therefor is required. Since it is unnecessary, it can be constructed at a low cost.

Further, in the embodiment of FIG. 3, when the heating input means 4 has a heating setting input, the timer means 9 receives this signal and displays on the display means 10 a prompt for timekeeping input.
When performing pressure cooking, the user inputs the setting of the pressure cooker with the heating input means 4, and in response to this, the heater control unit 8 controls the heater 2 until the water in the cooking vessel 1 boils.
Is heated by applying electricity, and after boiling, the boiling is continued for a preset time. At this time, the preset time is the time set by the clock input means 4. That is, the setting of the timer is indispensable for cooking the pressure cooker, and in the present embodiment, when the heating input means 4 has the input setting of the pressure cooker, the timer means 9 receives this and displays the time on the display means 10. Display a prompt for input. This can prevent the user from forgetting the settings.

Further, in the embodiment shown in FIG. 4, when the heating input means 4 receives a heating setting input, the time counting prohibiting device 12 outputs a reset signal to the timer means 9. Upon receiving this signal, the timer means 9 resets the display of the timekeeping input on the display means 10 and prohibits the input from the timekeeping input means 5. For example, when performing the automatic boiling detection cooking, the user inputs the setting of the automatic boiling detection cooking by the heating input means 4, and the heater control unit 8 receives the setting input until the water in the heating cooking container 1 boils. The heater 2 is energized and heated, and when boiling is detected, the heater 2
Stop supplying power to Here, the automatic boiling detection cooking does not coexist with the setting of the timer in cooking when the user desires boiling water. In the present embodiment, the timer means 9 receives the automatic boiling detection cooking input setting in the heating input means 4, and resets the timer setting from the time counting input means 5 by that time. Then, the timekeeping display of the display means 10 is erased and the input from the timekeeping input means 5 is prohibited. As a result, the user's setting error can be eliminated.

Further, in the embodiment shown in FIG. 5, when the heating input means 4 receives the heating setting input, the second timer means 13 starts the time counting and measures the predetermined time. The heating time of the heater 2 in normal cooking is about 20 to 30 minutes, and the cooking is not performed for more than 45 minutes. That is, the predetermined time is 45 minutes in this embodiment, and if there is no heating stop input to the heating input means 4 during this time, it is considered that the user has forgotten to stop heating the device, and the heater control unit 8 is instructed. Outputs a heating stop signal. In this way, the second timer means 13 operates as a safety device for preventing forgetting to turn off. However, depending on cooking, such as stew cooking, the timer means 9
Continuous heating for about 2 hours may be required. When the timer operation setting is made by the time counting input means 5, the timer means 9 prohibits the operation of the second timer means 13 so that it does not expire in 45 minutes and gives priority to the setting by the time counting input means 5. To do. As a result, it is possible to realize an electric cooking heater in which a safety device and a timer function coexist.

Further, in the embodiment shown in FIG. 6, when the temperature detected by the temperature detecting means 14 reaches the temperature set in the heating input means 4, the timer means 9 starts time counting and measures the predetermined time.
For example, when cooking with a pressure cooker, the heating input means 4
Then, the user inputs the setting of the pressure cooker, and in response to this, the heater control unit 8 energizes the heater 2 to heat until the water in the cooking vessel 1 boils. Then, when the water in the heating cooking container 1 boils, the temperature of the bottom of the container becomes about 120 ° C., and when the temperature is adjusted at 120 ° C. thereafter, the boiling of the water in the heating cooking container 1 continues. Cooking with a pressure cooker is an important requirement for cooking, in which the water is kept boiling for a while. The user sets the boiling maintaining time with the timekeeping input means 4, and inputs the setting of the pressure cooker with the heating input means 4. In response to this, the heater control unit 8 causes the water in the cooking vessel 1 to boil. That is, the temperature detected by the temperature detecting means 14 is 120 ° C.
The heater 2 is energized and heated until the temperature reaches, and thereafter the output of the heater 2 is controlled by setting the temperature detected by the temperature detecting means 14 at 120 ° C. The arrival detection means 15 detects that the temperature detected by the temperature detection means 14 is
When the temperature reaches 120 ° C., the arrival is detected, and a timer start signal is output to the timer means 9. Timer means 9
Does not operate until the start signal is received even if the time counting means 4 sets the time counting time, starts the time counting after the water in the cooking vessel 1 boils, and when the set time is reached, the heater control is performed. A heating stop signal is output to the unit 8, and the heater control unit 8 receives the signal and ends the cooking. That is, the power supply to the heater 2 is stopped. In this case, if the boiling duration is set at the start of heating, the cooking is automatically performed thereafter.

Further, in the embodiment shown in FIG. 7, when there is a heating setting input to the heating input means 4, the third timer means 16 starts the time measurement and measures the predetermined time. The heating time of the heater in normal cooking is about 20 to 30 minutes, and heating is not performed for more than 45 minutes. That is, the predetermined time is 45 minutes in the present embodiment, and if there is no heating stop input to the heating input means 4 during this time, it is considered that the user forgets to stop heating the device, and the heater control unit 8 is heated. The stop signal of is output. When the temperature detected by the temperature detecting means 14 reaches the set value within the predetermined time, the arrival detecting means 15 stops the operation of the third timer means 16. As a result, the heating time of the heater 2 is prioritized by the setting of the timer means 9. That is, when the detected temperature of the temperature detecting means 14 reaches the set value, the energization of the heater 2 is stopped after the set time of the timer means 9 elapses. However, if the detected temperature does not reach the set value for some reason, The third timer means 16 outputs a current stop signal for the heater 2 to the heater control section 8 after the third timer means 16 measures a predetermined time so that the apparatus can be stopped safely, thereby providing a safe electric cooking heater.

Next, the operation of the embodiment shown in FIG. 8 will be described with reference to the flow charts shown in FIGS.

When voltage is applied to the circuit from AC power supply 21, DC power supply
A DC voltage output is generated by 24, and the operating voltage is supplied to the microcomputer 25. As a result, the microcomputer 25 starts operation from step 41 of the flowchart. In step 42, the microcomputer 25 is initialized, the RAM of the storage unit 28 is cleared, the output Q of the transistor Q ₁ is turned off from the output unit 21, the relay switch 23S is turned off, and the liquid crystal display means 38
Is displayed as an input standby display, and is initially set in a state of waiting for a user operation. Next, in steps 43 and 44, if there is an input, the heating setting from the input switch 30 is input and accepted from the input section 26. Similarly, in steps 45 and 46, the heating setting input from the input switch 30 is received, and if there is an input. Accept. Next, step 47
Then, the temperature detected by the thermistor 32 is changed to the A / D converter 3
Input from the input unit 26 via 3, and stored in the storage unit 28,
The current temperature of the cooking vessel 1 is constantly monitored. Next, at step 48, by turning on and off the transistor Q ₁ via the output section 27, an output according to the set heating mode, the contact of the relay switch 23S is opened and closed, and the heater 2
Conduct by energizing 2.

Next, at step 49, clocking is performed according to the set timer mode. In steps 50 and 51, when the timer counted in step 49 ends or when there is an input to stop the cooking from the input switch 30, jump to step 52, stop the output of the heater 22, It ends at 53. In other cases, the process jumps from step 51 to step 43, and thereafter steps 43 to 51 are repeatedly operated in a time division manner.

FIG. 10 shows steps in the flowchart of FIG.
49 shows a detailed flowchart of 49. This second
The operation of the present embodiment will be described in more detail with reference to FIG. 10.When the user operates the input switch 30 to set the high output of heating and the setting of the timer to start after changing the heating power, the microcomputer 25 makes a step. This input is judged between 43 and 46 and stored in the storage unit 28. Step 49 Step 54
The operation is started from, and in this case, since the timer has been set in step 55, the process proceeds to step 56. In this case, since it is a timer after changing the firepower, further steps
Step 57, step 58. In step 58, it is detected that the current setting is high thermal power output from the stored contents of the storage unit 28 according to the settings input in steps 43 to 44, the process proceeds to steps 66 to 68 to 69, and the timer counts. The operation ends. The timer does not operate in the above operation. By the way, depending on how well the user cooks,
When the heating high output setting is changed to a low output by operating the input switch 30, the microcomputer 25 determines this input during steps 43 to 46 and stores it in the storage unit 28. In step 58, it is detected from the stored contents that the current setting is low thermal power output, and the process proceeds to step 59 to count down the timer. The countdown of the timer is performed by a series of time division processing between steps 43 and 51,
When the set time is reached, the end is detected in step 50, the process jumps to step 52, and the relay switch 23S is released to stop energizing the heater 22 and end. In this case, an electric cooking heater can be obtained in which the timer count starts automatically simply by changing the heating power setting.

Similarly, the user operates the input switch 30 to set and input the start of heating. Thereafter, when a timer setting input is performed, the microcomputer 25 determines this input and stores in the storage unit 28 that the general timer mode is set. In step 56, since it is a general timer, the process proceeds to step 60, and at this point, the setting input is still set for the timer operation and the counting is not permitted, and in step 61, the setting input is in progress. Therefore, if two seconds or more have not elapsed from the timer input operation, jump to step 66,
This state is continued. The lapse of 2 seconds or more can be realized by configuring a timer inside the microcomputer 25 that clears the count each time the switch operation is detected. After setting the timer time, input switch
When the operation of 30 has disappeared and 2 seconds have elapsed, this is detected in step 61 and the process proceeds to step 62 where it is stored in the storage unit 28 so that the counting of the timer is permitted.
Then, with this storage, the process proceeds to step 59, and the timer counts down. In this case, after setting the timer time, the timer can be automatically started without inputting a timer start signal, the setting is facilitated, and forgetting to input the start can be prevented.

FIG. 11 shows the steps in the flowchart of FIG.
44 shows a detailed flowchart of 44. This second
The operation will be described with reference to FIG. User input switch 30
When the timer setting is input by the operation of, the microcomputer 25 judges this input and stores in the storage unit 28 that the general timer mode is set. Next, a heating setting input is made, but at this time it is not yet done. At step 43, if there is no heating setting input, step 44 is skipped and step 45 is proceeded to.
In this case, nothing happens if only the timer is set. Next, when you set the heating from the input switch 30, step
The routine proceeds from 43 to step 44, and as the internal operation of this step 44, since the general heating is performed in step 71, the routine proceeds to step 72, and the general operation is also performed in step 72, the routine proceeds to step 73. Since the timer has been set in step 73, the process proceeds to step 74. In this step 74, counting of the timer is permitted, and the process proceeds to step 77. Then, in step 77, the heating setting mode is set in the storage unit 28, and the process proceeds to step 78. In step 48, the heating output of the heater 22 is set based on the memory of the box setting. In step 49, since the timer count is permitted, the timer is counted down thereafter, and when the set time is counted, the heating of the heater 22 is stopped. In this case, after setting the timer time, the timer can be automatically started without inputting a timer start signal, the setting is facilitated, and forgetting to input the start can be prevented.

Similarly, the user operates the input switch 30 to set and start the heating of the pressure cooker. By this input, the process proceeds to step 43 to step 44. Since the internal operation of step 44 is heating by the pressure cooker at step 71, the process proceeds to step 75, and the microcomputer 25 displays the liquid crystal display means 38 via the output unit 27. The timer time "0:00" and the cooking timer display, that is, the same display as after receiving the input to start the setting of the timer, are displayed, and the pressure cooker cooking mode setting is set in the storage unit 28 in step 27. , Go to step 78. In step 48, the heating output of the heater 22 is set based on the memory of the box setting. As a result, it is possible to prevent the user from forgetting the setting, and the input for starting the setting of the timer is omitted.

Similarly, when the user operates the input switch 30 to input a timer setting, the microcomputer 25 determines this input and stores the general timer mode setting. At this point, the setting input for heating has not yet been made, so in step 43 step 44 is skipped and step 45 is proceeded to. Nothing works just by setting the timer. Next, by operating the input switch 30, the heating start of the boiling water detection heating is set and input. With this input, the process proceeds to step 43 to step 44. As the internal operation of step 44, since the boiling water detection mode is set in step 71, the process proceeds to steps 72 and 76, and the microcomputer 25 outputs the output unit 27.
The setting display of the timer time is displayed on the liquid crystal display means 38 via, and the memory of the mode setting of the cooking timer in the storage unit 28 is erased. Automatic boiling detection cooking does not coexist with the timer setting.If there is an automatic boiling detection cooking input setting, if there is a timer setting, that setting is reset and the time display of the liquid crystal display means 10 is erased. To do. As a result, the user's setting error can be eliminated.

Further, the storage unit 28 and the arithmetic control unit 29 of the microcomputer 25 are configured so that, when the user forgets to stop the device during cooking, a predetermined time elapses after the user last operates the input switch 30. It is to stop, and this constitutes the function of preventing forgetting to turn off. Further, in step 66, in the case of heating and cooking without a timer set, the timer is counted in step 67 and a safe operation is performed. If the timer is set, in step 66, the process proceeds to step 68, and in the case of timer cooking other than the pressure cooker, the process jumps to step 67 and proceeds to step 69. As a result, the forget-to-cut timer does not operate, and the set timer has priority and operates. If the timer operation is set, the operation of the forget-to-cut timer means is prohibited so that it does not expire in 45 minutes, and the timer setting is given priority to operate. As a result, an electric cooking heater having a safety device and a timer function coexisting can be obtained.

Similarly, when cooking with a pressure cooker, the boiling maintaining time after boiling water is an important requirement for cooking. The user sets the boiling example time with the input switch 30, and then inputs the setting for cooking with the pressure cooker. In this case, step 54
Since it is cooking with a pressure cooker, steps 55-56
~ 57 ~ 63 ~ 64, if not reached in step 64, proceed to step 66, the countdown of the set timer is not performed. When the cooking container 1 is heated and its temperature rises, the microcomputer 25 detects this from the thermistor 32 via the A / D converter 33 through the input unit 26. Step 48
In the heating output setting of, since it is the heating by the pressure cooker starting from step 79 in FIG. 12 as the internal processing, the temperature control mode is entered and the process proceeds to step 81,
In 81, the set temperature has not been reached, so the process proceeds to step 83, and in this step 83, the current temperature is ± 10 of the set temperature.
If the current temperature is lower than the set temperature, the heating operation is performed, and if the current temperature is higher than the set temperature, the rest operation is performed between the steps 85 and 87. When the current temperature falls within ± 10% of the set temperature, it is determined that the set temperature has been reached, and in step 84, the process of reaching, that is, the timer count permission is stored.
Store it in 28. Even if the set time is set, the set timer does not operate until the count permission by this arrival is received, and the clock in the heating and cooking container 1 is boiled and the count is given, and when the set time is reached, heater
A heating stop signal is output to 22 to end heating and cooking, that is, stop energizing the heater 22. In this case, if the boiling duration is set at the start of heating, the cooking is automatically performed thereafter.

Similarly, in step 68 of FIG. 10, only when the cooking setting by the pressure cooker has not been reached, the process jumps to step 67 to perform the countdown operation of the forget-to-cut timer.
If the timer for forgetting to turn off and the set temperature for cooking with the pressure cooker have not reached, it is unlikely that the timer can operate even if left as it is.
It outputs 22 power-off signals, which provides a safe electric cooking heater.

EFFECTS OF THE INVENTION As is clear from the description of the above embodiments, according to the present invention, it is possible to obtain an electric cooking heater capable of controlling the timekeeping operation of the timer in accordance with the cooking of the heating set, and as a result, For example, in boiled egg cooking, when the user weakens the heating power after boiling, the heating is stopped after a preset time, so that there is no excessive cooking as in the past.

Also, in pressure cooker cooking, heating is stopped after a preset time after boiling, which improves usability.

In addition, in the case of taking out the dashi or simply boiling the water, the heating is stopped immediately after the boiling is detected, which is also convenient.

Furthermore, in cooking that does not use a timer, the so-called "forget-to-remember prevention timer" that stops heating at a predetermined time from the start of heating works, while when setting the heating time of a predetermined part of the cooking process such as cooking stew, "Forgot to cut timer" is disabled, so "Forgot to cut timer"
No need to restart heating every time when works, eliminating the hassle.

Also, for example, when the boiling temperature is set to about 120 ° C and cooking is continued for a predetermined time in order to cook the pressure cooker at about 2 atm, the pressure adjustment valve is open. If you put the wrong pot in the wrong place, it won't reach the set temperature of 120 ℃ until it is cooked empty.
Since the third timer stops heating after a predetermined time,
It can be an extremely safe electric cooking heater.

In addition, complicated cooking using a timer is possible, and the settings can be input all at once at the start of cooking, which makes it easier for the user to perform setting operations and reduces the hassle of setting. Is something that can be done.
