[0033] That is, when the current example the door 16 the door switch 18 is turned ON from the open state in the closed control operation of the control unit 20 is started, the operation data of the operation keys is inputted first, in step S ₁ You.

Next, based on the input data, step S ₂
It is determined whether or not the rice cooking key 38b has been turned ON. As a result, when the rice cook key 38b is not turned on (NO), the control ends without executing the rice cook control sequence described later.

On the other hand, when the rice cooker key 38b is turned ON, Y
When ES further proceeds to step S _3, this time determines whether the finish adjustment key 38a is turned ON.

[0036] Then, when the YES to finish adjustment key 38a is turned ON, the further step S ₄ or S ₁₉
And the setting level of the finish adjustment key 38a is weak.
(0.5 go), medium (1-1.5 go) or weak (0.5 go) even medium (1-1.
It is determined whether the strength is not strong (5 go) or not (2 go), that is, the number of go is determined.

[0037] As a result, when the determination weak (0.5 Go), first moves to the water absorption step of the 0.5 Go control sequence, the process proceeds to step S _5, the duty ratio 5/16 (maximum output the output of the magnetron 13 (16/16 = 500W) ×
5/16 = approximately 150 W) and the predetermined set time t ₁ (t ₁ =
(5 minutes) Perform internal water absorption heating. Thereafter, it followed the course of the water heating time t ₁ at step S ₆ (5 min) is determined, once a predetermined set time t ₂ and the magnetron 13 to the OFF (t ₂ = 5 min) in step S ₇ in The immersion state at a predetermined temperature is continued to perform sufficient water absorption.

Next, the dipping set time t ₂ in step S ₈ (5

00W), and the range is heated, and the full 0.5-g rice is cooked with full power.

[0039] Thereafter, the humidity sensor 1 at step S ₁₀
5 inputs a detection value V, it determines whether the detected value V in the subsequent step S ₁₁ becomes the first set value 13H more. The first humidity set value (13H) is compared with that of a sequence (1 to 1.5, 2) to be described later corresponding to the total number of the sequence being 0.5 and the least amount of cooked rice. Set to a low value.

[0040] The result of the determination, YES, i.e. when the boiling state is detected, 5/16 the output duty ratio of the magnetron 13 then proceeds to step S ₁₂ (about 150
W), and performs level heating for a predetermined set time t ₃ (t ₃ = 17 minutes).

[0041] Thereafter, heating time t ₃ in step S ₁₃ (1
Determining the course of 7 minutes), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₁₄ and ends the "cook-up process".

[0042] Then, further proceeds to "steaming process" in step S ₁₅ follows.

[0043] In step S _15, first, the above-described heater Hu
Is turned on to execute the heater heating within the predetermined set heating time t ₄ (t ₄ = 1 minute and 30 seconds) corresponding to the total number 0.5.

[0044] After that, the heating time t ₄ at step S ₁₆ (1
Determining an elapsed minute 30 seconds) and become to YES, the process proceeds to step S _17, to OFF the heater Hu.

Thereafter, the heater OFF time is continued for a predetermined set time t ₅ (t ₅ = 8 minutes), and the unevenness due to the residual heat is executed.

[0046] Then, finally, to determine the course of該余heat time t ₅ in step S _18, when becomes YES after lapse of said time t _5, and terminates the control of the white rice cooking sequence of the 0.5 Go.

Thus, the white rice for the 0.5 combination is automatically cooked in an optimally cooked state by the 0.5 rice total rice cooker control sequence selected by the weak level setting of the finishing adjustment key 38a. become.

Meanwhile, unlike the above, when it is determined in step S ₄ NO, in setting the level of the YES and the determined finish adjustment key 38a is determined in step S _19, that is if the number of (B) 1 to 1.5 when the selection of the multiplexer have been made, first proceeds to step S ₂₀ is "water process" of the same sequence side,
The output of the magnetron 13 is set to a duty ratio of 7/16.
(Maximum output (16/16 = 500W) × 7/16 = about 20
0 W) and perform water absorption heating for a predetermined set time t ₁ (t ₁ = 5 minutes). Thereafter, the water heating time at the subsequent step S ₂₁
t ₁ If the course of (5 min) is determined, a predetermined set time once by the magnetron 13 to OFF in step S ₂₂ t ₂ (t ₂
= 5 minutes), the immersion state at a predetermined temperature is continued, and sufficient water absorption is performed.

Next, the dipping set time in step S ₂₃ t
₂ has elapsed is determined (5 minutes), when the time t ₂ has elapsed, subsequently moved to "cook up process", first maximum output duty ratio of the magnetron 13 in step S ₂₄ outputs 16/1
6 (500W), range heating is carried out, and the full-powered rice of 1.5-1.5 is cooked with full power.

[0050] Thereafter, the humidity sensor 1 at step S ₂₅
5 inputs a detection value V, the detected value V in the subsequent step S ₂₆ it is determined whether or not a second set value 15H more. The second humidity set value (15H) corresponds to the sequence (0.5 ratio) and the sequence described later corresponding to the total number of the sequence being 1 to 1.5 and the amount of cooked rice being an intermediate amount.
The value is set to an intermediate value between the two values.

The above results of judgment, YES, i.e. when the boiling state is detected, 6/16 the output duty ratio of the magnetron 13 then proceeds to step S ₂₇ (about 180
W), and performs range heating for a predetermined set time t ₃ (t ₃ = 17 minutes).

[0052] After that, the heating time t ₃ in step S ₂₈ (1
Determining the course of 7 minutes), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₂₉ and ends the "cook-up process".

[0053] Then, further proceeds to "steaming process" in step S ₃₀ follows.

[0054] In step S _30, first, the above-described heater Hu

[0055] After that, the heating time t ₄ at step S ₃₁ (1
Determining an elapsed minute 30 seconds) and become to YES, the process proceeds to step S _32, to OFF the heater Hu.

Thereafter, the heater OFF time is continued for a predetermined set time t ₅ (t ₅ = 8 minutes), and the unevenness due to the residual heat is executed.

[0057] Then, finally, to determine the course of該余heat time t ₅ in step S _33, when becomes YES after lapse of said time t _5, and terminates the control of the white rice cooking sequence of the 1.5 Go.

Thus, according to the white rice cooking control sequence of the total number of 1 to 1.5 selected by the middle level setting of the finishing adjustment key 38a, the white rice of the same number of 1 to 1.5 is automatically set to the optimum cooked state. Be able to cook.

[0059] On the other hand, At the even weak setting level by finishing control key 38a, which is determined as NO in the determination in step S ₁₉ also varies (0.5 Go), strong nor medium (1.5 Go), i.e. of 2 Go when the number of engagement is selected, first proceed towards the step S _34, passes to the water absorption step, outputs the duty ratio 12/16 (maximum output of the magnetron 13 (16/16 = 500W) × 12/16 = About 300W)
To perform water absorption heating within a predetermined set time t ₁ (t ₁ = 5 minutes). Thereafter, the water heating time at step S ₃₅ subsequent t
₁ the course of (5 min) is determined, a predetermined set time once by the magnetron 13 to OFF in step S ₃₆ t ₂ (t ₂
= 5 minutes), the immersion state at a predetermined temperature is continued, and sufficient water absorption is performed.

Next, the immersion set time in step S ₃₇ t
₂ has elapsed is determined (5 minutes), when the time t ₂ has elapsed, subsequently moved to "cook up step" First Step S ₃₈ maximum output an output duty ratio of the magnetron 13 by 16/1

The third humidity setting value (17H) is compared with that of the two sequences (0.5 and 1-1.5) corresponding to the fact that the total number of the sequences is 2 and the amount of cooked rice is the largest. And is set to the highest value.

[0062] The result of the determination, YES, i.e. when the boiling state is detected, 7/16 the output duty ratio of the magnetron 13 then proceeds to step S ₄₁ (about 200
W), and performs range heating for a predetermined set time t ₃ (t ₃ = 17 minutes).

[0063] After that, the heating time t ₃ in step S ₄₂ (1
Determining the course of 7 minutes), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₄₃ and ends the "cook-up process".

[0064] Then, further proceeds to "steaming process" in the following steps S _44.

[0065] In step S _44, first, the above-described heater Hu
Is set to ON and the predetermined set heating time corresponding to the above 2

[0083] Thereafter, heating time in step S ₁₆ t ₄ (2
Determining the elapsed minute), it becomes to YES, the process proceeds to step S _17, to OFF the heater Hu.

Thereafter, the heater OFF time is continued for a predetermined set time t ₅ (t ₅ = 8 minutes), and the unevenness due to the residual heat is executed.

[0085] Then, finally, to determine the course of該余heat time t ₅ in step S _18, when becomes YES after lapse of said time t _5, the control of the rice cooking sequence該炊can divide level "harder" finish.

Thus, the white rice is automatically cooked in the optimal cooked state of “Kakame” by the rice cooker control sequence of the “Kakame” cooking division level selected by the strong level setting of the finishing adjustment key 38a. Be able to raise.

[0087] On the other hand, unlike the above, when in setting the level of the YES and the determined finish adjustment key 38a is determined in the determination NO, a step S ₁₉ in step S ₄ is, that is,
When cooked separately select the level "normal" is made, proceed to "water process" ordinary sequence of steps S _20,
The output of the magnetron 13 is set to a duty ratio of 5/16.
(Maximum output (16/16 = 500W) × 5/16 = about 15
0 W) and perform water absorption heating for a predetermined set time t ₁ (t ₁ = 5 minutes). Thereafter, the water heating time at the subsequent step S ₂₁
t ₁ If the course of (5 min) is determined, a predetermined set time once by the magnetron 13 to OFF in step S ₂₂ t ₂ (t ₂
= 5 minutes), the immersion state at a predetermined temperature is continued, and sufficient water absorption is performed.

[0088] Next, the dipping set time in step S ₂₃ t
₂ has elapsed is determined (5 minutes), when the time t ₂ has elapsed, subsequently moved to "cook up process", first maximum output duty ratio of the magnetron 13 in step S ₂₄ outputs 16/1
Set to 6 (500W), perform range heating, and cook with full power.

[0089] Thereafter, the humidity sensor 1 at step S ₂₅
5 inputs a detection value V, the following step S ₂₆ in the detection value V and determines whether it is a more second set value 14H. The second humidity set value (14H) is compared with that of the above-described sequence (hard) and the later-described sequence (soft) corresponding to the cooking level of the sequence being “normal”. , Are set to values in between.

[0090] The above results of judgment, YES, i.e. when the boiling state is detected, 6/16 the output duty ratio of the magnetron 13 then proceeds to step S ₂₇ (about 180
W), and performs range heating for a predetermined set time t ₃ (t ₃ = 17 minutes).

[0091] After that, the heating time t ₃ in step S ₂₈ (1
Determining the course of 7 minutes), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₂₉ and ends the "cook-up process".

Then, the process proceeds to the “irregularity process” following step S ₃₀ .

[0093] In step S _30, first, the above-described heater Hu
Is turned on to perform heater heating within a predetermined set heating time t ₄ (t ₄ = 1 minute and 30 seconds) corresponding to the above cooking level “normal”.

[0094] Thereafter, heating time t ₄ in step S ₃₁ (1
Determining an elapsed minute 30 seconds) and become to YES, the process proceeds to step S _32, to OFF the heater Hu.

After that, the heater OFF time is set to a predetermined set time t ₅ (t ₅₎ corresponding to the cooking level “normal”.
= 7 minutes), and continue to perform the unevenness due to residual heat.

[0096] Then, finally, to determine the course of該余heat time t ₅ in step S _33, when becomes YES after lapse of said time t _5, terminates the control of the white rice cooking sequence該炊can divide level "normal" I do.

Thus, the rice of the same level is automatically cooked in an optimally cooked state by the white rice cooking control sequence of the cooking level "normal" selected by the middle level setting of the finishing adjustment key 38a. become.

[0098] On the other hand, but this and the strength set level by finishing control key 38a, which is determined as NO in the determination in step S ₁₉ also varies (harder), the weak nor medium (usually),
That is, when the cook divided level of "softer" is selected, proceed towards softer sequence of steps S _34, first moves to its water absorption step, the magnetron 13
Output at a duty ratio of 5/16 (maximum output (16/16
= 500 W) × 5/16 = approximately 150 W) to perform water absorption heating within a predetermined set time t ₁ (t ₁ = 5 minutes). Thereafter, followed the course of the water heating time t ₁ at step S ₃₅ (5 min) is determined, once the magnetron 13 in step S ₃₆ O
The immersion state at a predetermined temperature is continued for a predetermined set time t ₂ (t ₂ = 5 minutes) by setting to FF, and sufficient water absorption is performed.

[0099] Next, the immersion set time in step S ₃₇ t
₂ has elapsed is determined (5 minutes), when the time t ₂ has elapsed, subsequently moved to "cook up step" First Step S ₃₈ maximum output an output duty ratio of the magnetron 13 by 16/1
6 (500 W), microwave heating is performed, and the two sets of white rice are cooked with full power.

[0100] Thereafter, the humidity sensor 1 at step S ₃₉
5 inputs a detection value V, the following step S ₄₀ in the detection value V is determined whether or not a third set value 13H more. The third humidity set value (13H) corresponds to the cooking level of the sequence being “soft” and the need for the most required amount of water. It is set to the lowest value compared to the one.

As a result of the determination, if YES, that is, if the boiling state is detected, the process proceeds to step _S41 , where the output duty ratio of the magnetron 13 is set to 5/16 (about 150).
W), and performs range heating for a predetermined set time t ₃ (t ₃ = 17 minutes).

[0102] After that, the heating time t ₃ in step S ₄₂ (1
Determining the course of 7 minutes), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₄₃ and ends the "cook-up process".

[0103] Then, further proceeds to "steaming process" in the following steps S _44.

[0104] In step S _44, first, the above-described heater Hu
Is turned on to perform heater heating within a predetermined set heating time t ₄ (t ₄ = 1 minute) corresponding to the above cooking level “soft”.

[0105] Thereafter, heating time t ₄ in step S ₄₅ (1
Determining the elapsed minute), it becomes to YES, the process proceeds to step S _46, to OFF the heater Hu.

After that, the heater OFF time is continued for a predetermined set time t ₅ (t ₅ = 6 minutes) corresponding to the cooking level “soft”, and the unevenness due to residual heat is executed.

[0107] Then, finally, to determine the course of該余heat time t ₅ in step S _47, when becomes YES after lapse of said time t _5, the control of the rice cooking sequence該炊can divide level "softer" finish.

Thus, the "soft" rice white rice cooking control sequence selected by the low level setting of the finishing adjustment key 38a allows the rice at the same cooking level to be automatically cooked in an optimally cooked state. become.

(3) Third Embodiment Next, FIGS. 6 and 7 show a high-frequency heating apparatus according to a third embodiment of the present invention and the contents of automatic rice cooking control thereof.

In the automatic rice cooking control of the first and second embodiments, the case of white rice cooking control has been described as an example in both cases.

However, the rice cooking is not limited to the case of the white rice cooking described above, and for example, "rice cooked rice" is often cooked.

However, the “cooked rice” takes more time to absorb water and heat than rice cooked rice, because it contains ingredients and seasonings. Therefore, it is not possible to cope with such a case simply by enabling the rice cooking control in accordance with the total number and the cooking level as described above.

Therefore, in this embodiment, as shown in FIG. 6, for example, by providing a cooking key 38g separately from the white rice cooking key 38b in FIG. 1, the rice cooking and the cooking rice can be optimally separated. It is characterized by having.

Next, the contents of the control will be described in detail with reference to the flowchart of FIG.

[0115] That is, when the current example the door 16 the door switch 18 is turned ON from the open state in the closed control operation of the control unit 20 is started, the operation data of the operation keys is inputted first, in step S ₁ You.

[0116] Then, based on the input data, first determines first the white rice cooking key 38b in step S ₂ is whether or not ON-operated. As a result, the white rice cooking key 38b is ON
When unmanipulated NO further turn determines whether the key 38g is turned ON cooked proceeds to step S _3. As a result, when neither of them is turned on, the control ends without executing all the rice cooking control sequences described later.

[0117] On the other hand, when in step S ₂ of white rice cooking key 38b is turned ON YES, first proceed to water absorption process of rice cooking sequence of steps S _4, the duty ratio output of the magnetron 13 5/16 (Maximum output (1
6/16 = 500 W) × 5/16 = approximately 150 W) to perform water absorption heating for a predetermined set time t ₁ (t ₁ = 5 minutes). Thereafter, it followed the course of the water heating time t ₁ in step S ₅ (5 min) is determined, once a predetermined set time t ₂ and the magnetron 13 to the OFF (t ₂ = 5 min) in step S ₆ in The immersion state at a predetermined temperature is continued to perform sufficient water absorption.

[0118] Next, the dipping set time t ₂ in step S ₇ (5
Determining the elapsed minute), when the time t ₂ has elapsed, subsequently moved to "cook up step" First Step S ₈ maximum output an output duty ratio of the magnetron 13 in 16/16 (5
(00 W), the range heating is performed, and the predetermined amount of white rice is cooked with full power.

[0119] Thereafter, the humidity sensor 1 at step S ₉
5 inputs a detection value V, it determines whether the detected value V in step S ₁₀ that follows is a first set value 13H more. The first humidity set value (13H) is set to a value lower than that in the case of the control sequence of cooked rice, which will be described later, corresponding to the case where the control sequence is white rice cooking.

[0120] The above results of judgment, YES, i.e. when the boiling state is detected, 5/16 the output duty ratio of the magnetron 13 then proceeds to step S ₁₁ (about 150
W), and performs range heating for a predetermined set time t ₃ (t ₃ = 17 minutes).

[0121] After that, the heating time t ₃ in step S ₁₂ (1
Determining the course of 7 minutes), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₁₃ and ends the "cook-up process".

[0122] Then, further proceeds to "steaming process" in step S ₁₄ follows.

[0123] In step S _14, first, the above-described heater Hu
Turn ON and set the heating time for the rice cooked
Heater heating is performed within t ₄ (t ₄ = 1 minute and 30 seconds).

[0124] Thereafter, heating time t ₄ in step S ₁₅ (1
Determining an elapsed minute 30 seconds) and become to YES, the process proceeds to step S _16, to OFF the heater Hu.

Thereafter, the heater OFF time is continued for a predetermined set time t ₅ (t ₅ = 8 minutes), and the unevenness due to the residual heat is executed.

[0126] Then, finally, to determine the course of該余heat time t ₅ in step S _17, when becomes YES after lapse of said time t _5, and terminates the control of the sequence of the white rice cooking.

As a result, a predetermined amount of white rice is automatically cooked in an optimally cooked state by the predetermined amount of white rice cooking control sequence.

[0128] On the other hand, when the result of the decision in step S _3,
When the cooking key 38g determined to be YES is ON,
Proceed to water absorption process of cooked sequence of steps S _18, duty ratio 6/16 (maximum output outputs a slightly higher than in the case of the white rice cooking of the magnetron 13 (1
6/16 = 500 W) × 6/16 = approximately 180 W) to perform water absorption heating within a predetermined set time t ₁ (t ₁ = 5 minutes). Thereafter, followed the course of the water heating time t ₁ (5 min) is determined in step S _19, step S ₂₀ in once the magnetron 13 a longer predetermined set than in the OFF of the white rice cooking time t ₂ (t ₂ = 7 minutes) Continue the immersion state at a temperature slightly higher than the time of rice cooked inside white rice to perform more sufficient water absorption.

[0129] Next, the immersion set time in step S ₂₁ t
₂ has elapsed is determined (7 minutes), when the time t ₂ has elapsed, subsequently moved to "cook up process", first maximum output duty ratio of the magnetron 13 in step S ₂₂ outputs 16/1
6 (500W) and microwave heating is performed to cook the cooked rice with full power.

[0130] Thereafter, the humidity sensor 1 at step S ₂₃
5 inputs a detection value V, the following step S ₂₄ in the detection value V is determined whether or not a second set value 15H or higher than that at the white rice cooking.

[0131] As a result of this determination, YES, i.e. when the boiling state is detected, the output duty ratio of the magnetron 13 slightly higher than in the white rice cooking then proceeds to step S ₂₅ 6/16 (about 180 W) Then, range heating is performed for a predetermined set time t ₃ (t ₃ = 18 minutes), which is slightly longer than when cooking white rice.

[0132] Thereafter, heating time t ₃ in step S ₁₃ (1
Determining the course of 8 minutes), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₂₇ and ends the "cook-up process".

Then, the process proceeds to the “irregularity process” from step S ₂₈ .

[0134] In step S _28, first, the above-described heater Hu
Is turned on to perform heater heating within a predetermined set heating time t ₄ (t ₄ = 2 minutes) corresponding to the cooked rice.

[0135] After that, the heating time in the step S ₂₉ t ₄ (2
Determining the elapsed minute), it becomes to YES, the process proceeds to step S _30, to OFF the heater Hu.

After that, the heater OFF time is set to a predetermined set time t ₅ (t ₅ = 1) which is longer by two minutes than the above rice cooking.
(0 minutes) Continue to perform sufficient spotting by residual heat.

[0137] Then, finally, to determine the course of該余heat time t ₅ in step S _31, when becomes YES after lapse of said time t _5, the cooked ends the control of the white rice cooking sequence cooking.

Thus, the cooked rice selected and set by the cooking key 38g can be automatically cooked in an optimum cooked state by the cooked rice control sequence.

(4) Fourth Embodiment Next, FIGS. 8 to 10 show the configuration of a high-frequency heating apparatus according to a fourth embodiment of the present invention and the contents of automatic rice cooking control thereof.

[0140] Recently, there is a feeling of being full and low in calories,
In addition, digestible "porridge" has been reviewed, and it has been recognized not only as a conventional diet for sick people and baby food for infants, but also as a healthy diet for ordinary people. Under such circumstances, in recent toaster ranges and the like, a "porridge" rice cooking function is also added.

However, in the conventional method, as in the case of the white rice cooking, the rice is cooked only in a fixed heating sequence, and for example, (a) all the rice, (b) five minutes, (c) three minutes There was a problem that it was not possible to realize cooking of rice porridges having different moisture contents such as potatoes.

Therefore, in this embodiment, for example, as shown in FIG. 8, a dedicated porridge key 38h is provided separately from the rice cooking key 38b in FIG. The corresponding water-absorption and heating sequence (e.g., (a) is full, two times are (b) for 5 minutes, and three times (c) are three minutes, etc.) T ₁ ,
It is characterized in that selection and setting of t ₂ , t ₃ ) can be performed.

Next, the flowchart of FIG. 9 and the flowchart of FIG.
The content of the rice porridge rice cooking control will be described in detail with reference to the time chart of FIG.

[0144] That is, now for example, door 16 is a door switch 18 from the open state in the closed starts control operation of the control unit 20 turns ON, the operation data of each operation key is input first in step S ₁ .

Next, based on the input data, step S ₂
It is determined whether or not the rice porridge key 38h has been turned ON. As a result, when the rice porridge key 38h is not turned on (NO), the control ends without executing the rice cooking control sequence described later.

On the other hand, if the porridge key 38h has been turned ON, the process proceeds to steps S ₃ , S ₄ , and S ₂₅ , and
This time, it is determined whether the number of times the porridge key 38h is turned ON once, twice, or three times.

[0147] Then, first, when the number of times the porridge key 38h is turned ON is once, since the total Gayu of the above-described (i), the water absorption process of Step S ₅ is a control sequence of the entire Gayu Then, the output of the magnetron 13 is changed to a duty ratio of 5/16 (maximum output (16/16 = 500 W)).
× 5/16 = approximately 150 W) and set for a predetermined time t ₁ (t ₁
= 5 minutes) Heating by internal water absorption is performed. Thereafter, it followed the course of the water heating time t ₁ at step S ₆ (5 min) is determined, once a predetermined set time t ₂ and the magnetron 13 to the OFF (t ₂ = 5 min) in step S ₇ in The immersion state at a predetermined temperature is continued to perform sufficient water absorption.

[0148] Next, the dipping set time t ₂ in step S ₈ (5
Determining the elapsed minute), when the time t ₂ has elapsed, subsequently moved to "cook up step" First Step S ₉ maximum output an output duty ratio of the magnetron 13 in 16/16 (5
(00 W), the range is heated, and the white rice is cooked with full power.

[0149] Thereafter, the humidity sensor 1 at step S ₁₀
5 inputs a detection value V, it determines whether the detected value V reaches the set value 60H or in a succeeding step S _11. The humidity set value (60H) is set to a value corresponding to “porridge” rice cooking.

[0150] The above determination result, YES, i.e. when the boiling state is detected, 3/16 the output duty ratio of the magnetron 13 then proceeds to step S ₁₂ (about 100
W) and performs range heating for a predetermined set time t ₃ (t ₃ = 40 minutes).

[0151] Thereafter, heating time in step S ₁₃ t ₃ (4
Determining the course of 0 min), when the heating time t ₃ has elapsed, then the OFF the magnetron 13 in step S ₁₄ and ends the cook-up step of the "Zengayu".

As a result, according to the control sequence, the “zengayu” specified by the single pressing operation of the porridge key 38h is performed.
Is automatically and optimally cooked.

[0153] On the other hand, unlike the above, when NO in the determination in step S _3, the ON times of porridge key 38h it is determined YES in the determination in Step S ₄ twice, that is the
When the selection of 5 minutes Gayu of (b) have been made, first 5 minutes proceeds to water absorption process of step S ₁₅ is a control sequence of boiled, the duty ratio output of the magnetron 13 5
/ 16 (maximum output (16/16 = 500W) × 5/16 =
(150 W) and water absorption heating is performed for a predetermined set time t ₁ (t ₁ = 6 minutes). Thereafter, followed the course of the water heating time t ₁ at step S ₁₇ (6 minutes) is determined, a predetermined set time once by the magnetron 13 to OFF in step S ₂₂
During t ₂ (t ₂ = 6 minutes), the immersion state at a predetermined temperature is continued and sufficient water absorption is performed.

[0154] Next, the dipping set time in step S ₁₈ t
₂ to determine the course of (6 min), when the time t ₂ has elapsed, subsequently moved to "cook up process", first maximum output duty ratio of the magnetron 13 in step S ₁₉ outputs 16/1
6 (500W), microwave heating is performed, and the white rice is cooked with full power.

[0155] Thereafter, the humidity sensor 1 at step S ₂₀
5 inputs a detection value V, it determines whether the detected value V reaches the set value 60H or in a succeeding step S _21.

[0156] As a result of this determination, YES, i.e. when the boiling state is detected, 3/16 the output duty ratio of the magnetron 13 then proceeds to step S ₂₂ (about 100
W) and performs range heating for a predetermined set time t ₃ (t ₃ = 45 minutes).

As a result, according to the control sequence, the "five minutes" designated by the twice pressing of the rice porridge key 38h is automatically and optimally cooked.

[0158] On the other hand, this A is determined in but step S ₂₅ is judged NO in also different determination in step S ₄ Y
When ES been judged above porridge key 38h is 3 times ON engineered above (c) "3 Bungayu", first proceed towards the step S ₂₆ is a corresponding control sequence, the water absorption step And the output of the magnetron 13 is changed to a duty ratio of 5/16 (maximum output (16/16 = 500 W) × 5 /
16 = approximately 150 W) and a predetermined set time t ₁ (t ₁ = 7)
Min) to perform internal water absorption heating. Thereafter, followed the course of the water heating time t ₁ (5 min) is determined in step S _27, a predetermined set time t ₂ which temporarily 3 minutes by the magnetron 13 to the OFF corresponds to the boiled step S ₂₈ ( (t ₂ = 7 minutes) The immersion state at a predetermined temperature is continued within the period, and sufficient water absorption is performed.

[0159] Next, the dipping set time in step S ₂₉ t
₂ has elapsed is determined (7 minutes), when the time t ₂ has elapsed, subsequently moved to "cook up process", first maximum output duty ratio of the magnetron 13 in step S ₃₀ outputs 16/1
6 (500W), microwave heating is performed, and the white rice is cooked with full power.

[0160] Thereafter, the humidity sensor 1 at step S ₃₁
5 inputs a detection value V, it determines whether the detected value V reaches the set value 60H or in a succeeding step S _32.

As a result of this determination, if YES, that is, if the boiling state is detected, the process proceeds to step _S33 , where the output duty ratio of the magnetron 13 is set to 3/16 (about 100
W), and performs range heating for a predetermined set time t ₃ (t ₃ = 50 minutes).

[0162] Thereafter, heating time t ₃ in step S ₃₄ (5
Determining the course of 0 min), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF to end the increase cook of the "3 Bungayu" in step S _35.

As a result, according to the control sequence, the "three minutes gayu" designated by the three-time pressing operation of the porridge key 38h is automatically and optimally cooked.

(5) Fifth Embodiment Next, FIGS. 11 and 12 show contents of rice porridge rice cooking control of a high-frequency heating apparatus according to a fifth embodiment of the present invention.

The rice porridge rice cooking control of the fourth embodiment has been described on the assumption that rice porridge rice is cooked from white rice. However, usually "porridge" includes not only rice porridge cooked from white rice as described above, but also rice porridge cooked from rice, for example. The water absorption and heating sequences of these two are naturally different as shown in FIGS. 12 (a) and (b).

Therefore, in this embodiment, the rice porridge key 38h provided in the fourth embodiment is used, and when the number of ON operations is one, a rice porridge sequence from rice (FIG. 12 (b)).
But, on the other hand, the porridge sequence from two people
((A) of FIG. 12) are automatically set.

Hereinafter, the same two types of porridge cooking control will be described in detail with reference to the flowchart of FIG.

[0168] That is, now for example, door 16 is a door switch 18 from the open state in the closed starts control operation of the control unit 20 turns ON, the operation data of each operation key is input first in step S ₁ .

Next, based on the input data, step S ₂
It is determined whether or not the rice porridge key 38h has been turned ON. As a result, when the rice porridge key 38h is not turned ON, the control ends without executing the rice cooking control sequence described later.

[0170] On the other hand, when YES of porridge key 38h is ON operated, further proceeds to step S _3, S _10,
This time, the number of ON operations of the porridge key 38h is one,
Or it is determined twice.

That is, it is determined whether the porridge the user is about to cook is from rice or white rice.

[0172] As a result, when the ON operation number is porridge from one rice, subsequently moved to "cook up process", first maximum output an output duty ratio of the magnetron 13 in step S ₄ 16/16 = (500 W), and perform range heating to cook with full power.

[0173] Thereafter, the humidity sensor 1 at step S ₅
5 inputs a detection value V, it determines whether the detected value V becomes a predetermined set value 60H or in a succeeding step S _6.

[0174] Results of the determination, YES, i.e. when the boiling state is detected, 5/16 the output duty ratio of the magnetron 13 then proceeds to step S ₇ (about 150 W)
The range heating is performed for a predetermined set time t ₃ (t ₃ = 20 minutes), which is considerably shorter than the sequence from white rice described later.

[0175] After that, the heating time t ₃ in step S ₈ (20
Determining the elapsed minute), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₉ to end the porridge cook up from the rice.

Thus, according to the rice porridge rice cooking control sequence selected by pressing the rice porridge key 38h once, rice porridge from the rice can be automatically cooked in an optimally cooked state.

[0177] On the other hand, when the porridge key 38h at step S ₁₀ that has been turned ON twice is determined contrary to the above, recognizes a porridge from rice has been selected, the control sequence side corresponding thereto first moves to water absorption step, in step S _11, the duty ratio output of the magnetron 13 5/16 (maximum output (16/16 = 500W) × 5 of
/ 16 = approximately 150 W) and a predetermined set time t ₁ (t ₁ = 5)
Min) to perform internal water absorption heating. Thereafter, it followed the course of the water heating time t ₁ at step S ₁₂ (5 min) is determined, once a predetermined set time t ₂ and the magnetron 13 to the OFF (t ₂ = 5 min) in step S ₁₃ in The immersion state at a predetermined temperature is continued to perform sufficient water absorption.

[0178] Next, the immersion set time in step S ₁₄ t
₂ has elapsed is determined (5 minutes), when the time t ₂ has elapsed, subsequently moved to "cook up step" First Step S ₁₅ maximum output an output duty ratio of the magnetron 13 by 16/1
6 (500W), microwave heating is performed, and the white rice is cooked with full power.

[0179] Thereafter, the humidity sensor 1 at step S ₁₆
5 inputs a detection value V, it determines whether the detected value V becomes a predetermined set value 60H or in a succeeding step S _17.

[0180] Results of the determination, YES, i.e. when the boiling state is detected higher than the sequence from the rice output duty ratio of the magnetron 13 then proceeds to step S ₁₈ 6/16 (about 180 W) And the predetermined set time t ₃ (t
₃ = 40 minutes).

[0181] After that, the heating time in the step S ₁₉ t ₃ (4
Determining the course of 0 min), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF in step S ₂₀ and ends the increased cooking of porridge from the rice.

Thus, the rice porridge from the white rice selected by pressing the rice porridge key 38h twice can automatically cook the rice porridge from the white rice in an optimally cooked state.

(6) Sixth Embodiment Next, FIGS. 13 and 14 show the configuration of a high-frequency heating apparatus according to a sixth embodiment of the present invention and the contents of rice porridge rice cooking control.

In this embodiment, for example, when cooking rice porridge from rice, instead of providing a key dedicated to rice porridge as in the fourth embodiment, a rice cooking key 3 as shown in FIG.
8b, and the rice cooking key 38b and the finishing adjustment key 38
In combination with a, the water content of (a) is 5 minutes, (b) is 7 minutes, and (c) the total water content is different from that of the fourth embodiment.
It is a type of rice porridge that can be cooked separately.

Next, the contents of the control will be described in detail with reference to the flowchart of FIG.

[0186] That is, when the current example the door 16 the door switch 18 is turned ON from the open state in the closed control operation of the control unit 20 is started, the operation data of the operation keys is inputted first, in step S ₁ You.

Next, based on the input data, step S ₂
It is determined whether or not the rice cooker key 38b serving also as the porridge key has been turned ON. As a result, the same cooked rice / porridge key 3
When NO is not operated, the control is ended without executing the rice cooking control sequence described later.

[0188] On the other hand, when YES of rice / porridge key 38b is turned ON, the further proceeds to step S _3, this time determines whether the finish adjustment key 38a is turned ON.

Thus, according to the rice cooking control sequence selected by the high level setting of the finishing adjustment key 38a, the same five minutes can be automatically cooked in the optimum cooking state.

[0195] On the other hand, when the result of the decision in step S _11,
In (7 Bungayu) when the judgment is the 7 minutes passes to step up cooking control sequence of boiled, first, in step S _12, the maximum output 16 the duty ratio output of the magnetron 13
/ 16 (500W) and cook with a microwave.

[0196] Thereafter, the humidity sensor 1 at step S ₁₃
5 inputs a detection value V, it determines whether the detected value V becomes a predetermined set value 60H or in a succeeding step S _14.

[0197] Results of the determination, YES, i.e. when the boiling state is detected, then the output duty ratio of the magnetron 13 proceeds to step S ₁₅ 6/16 (about 180 W)
And performs range heating for a predetermined set time t ₃ (t ₃ = 25 minutes).

[0198] Thereafter, heating time t ₃ in step S ₁₆ (2
Determining the course of 5 minutes), when the heating time t ₃ has elapsed, the 5 minute finishes up cook boiled by the magnetron 13 to OFF in step S _17.

As a result, the 7-minute rice cooker control sequence selected by the medium-level setting of the finishing adjustment key 38a enables the 7-minute rice cooker to automatically cook in an optimally cooked state. .

[0200] On the other hand, when the result of the decision in step S _11,
Weak (Zengayu) When determination is moved to "cook up process" in the control sequence of the entire Gayu, first, in step S _18, the maximum output the duty ratio output of the magnetron 13 16 /
Set to 16 (500W), perform range heating, and cook with full power.

[0201] Thereafter, the humidity sensor 1 at step S ₁₉
5 inputs a detection value V, it determines whether the detected value V becomes a predetermined set value 60H or in a succeeding step S _20.

[0202] Results of the determination, YES, i.e. when the boiling state is detected, then the output duty ratio of the magnetron 13 proceeds to step S ₂₁ 6/16 (about 180 W)
To perform range heating for a predetermined set time t ₃ (t ₃ = 20 minutes).

[0203] Thereafter, heating time t ₃ in step S ₂₂ (2
Determining the course of 0 min), when the heating time t ₃ has elapsed, and the magnetron 13 to OFF to end the increase cook of the total Gayu in step S _23.

As a result, the rice cooker control sequence selected by the weak level setting of the finishing adjustment key 38a enables the rice cooker to automatically cook the rice in an optimum cooked state.
