[0032]
[Action]
According to the configuration of the first problem solving means, the rotation state of the motor is changed by a chaos signal, and the mixture is stirred, kneaded, and kneaded. Therefore, stirring, kneading, and kneading can be performed by making the path of movement of the cooking object irregular, and the uniformity of the cooking object can be improved.
[0033]
According to the configuration of the second problem solving means, the rotation change by the chaotic signal is obtained based on the rotation state of the motor according to the cooking process. Therefore, stirring, kneading, and kneading can be performed while maintaining the motor rotation state set according to the cooking process while changing the motor rotation in order to improve the uniformity of the object to be cooked.
[0034]
According to the configuration of the third problem-solving means, at the start of cooking, by performing weak rotation in a state of powder or the like until the food is mixed, stirring, kneading, kneading while suppressing scattering of the food to be cooked It can be performed.
[0035]
According to the configuration of the fourth problem solving means, after the spattering of the food to be cooked at the start of the rotary cooking is suppressed, and then, after thoroughly stirring, kneading, and kneading, the temperature of the food to be cooked is not raised. Stir, knead, knead cooking to reduce the strength of rotation.
[0036]
According to the configuration of the fifth problem solving means, by selecting a process from the cooking processes stored by inputting the cooking menu, each cooking menu is stirred and kneaded in a rotating state corresponding to the cooking process. Can knead cooking.
[0037]
According to the configuration of the sixth problem solving means, cutting cooking is performed by changing the rotation state of the motor by the chaotic signal. Therefore, the cut cooking which makes the path | route of the motion of a to-be-cooked item irregular can be performed, and the uniformity of the cut to-be-cooked item can be made favorable.
[0038]
According to the configuration of the seventh problem solving means, the rotation change by the chaotic signal is obtained based on the rotation state of the motor according to the cooking process. Therefore, cutting cooking which maintains the motor rotation state set according to the cooking process can be performed while changing the motor rotation in order to improve the uniformity of the object to be cooked.
[0039]
According to the configuration of the eighth problem solving means, by selecting a process from the cooking processes in which the cooking material is inputted and stored, the cut cooking with good uniformity of the cooking object according to the cooking material It can be performed.
[0040]
According to the configuration of the ninth problem solving means, by selecting a process from among the cooking processes stored by inputting the cooking menu, the cut cooking with good uniformity of the food to be cooked according to the cooking menu It can be performed.
[0041]
According to the configuration of the tenth problem solving means, the synthesizing means operates only when the output of the rotation state output means is larger than the threshold value, so that the rotation of the motor is changed by the chaotic signal only in a state where strong rotation is necessary. Stirring, kneading, kneading, and cutting cooking can be performed with good uniformity of the object to be cooked.
[0042]
According to the configuration of the eleventh problem solving means, only the ON time of the motor rotation is changed by the chaos signal, and the OFF time is made constant so that the cooked food can be uniformly mixed and kneaded with a simple program. Kneading and cutting can be performed.
[0043]
According to the configuration of the twelfth problem solving means, the ON time is changed by chaos, and the OFF time is subtracted from the predetermined time, thereby keeping the sum of the ON time and OFF time of the motor rotation constant. Can be changed by a chaos signal, and the easy-to-handle program that operates in a fixed cycle can perform mixing, kneading, kneading, and cutting with good uniformity of the food.
[0044]
According to the configuration of the thirteenth problem solving means, the ON time of the motor is changed based on the zero volt point, so the ON time by the chaos signal can be changed with high accuracy, and the uniformity of the food to be cooked is good. Can stir, knead, knead, cut and cook. In particular, when a chaos signal is used as the ON time, if the ON time is not changed with reference to zero volts, the ON time changes chaotically, but the motor driving force does not change chaotically. For example, when the ON point does not synchronize with the zero volt point, the first time is slightly delayed from the zero volt point, the second time is when the phase is delayed by 90 degrees from the zero volt point, that is, the half wave is at the highest point. Considering this, when the voltage at the time of turning on changes, the driving force of the motor also changes. Therefore, there is a case where the driving force of the motor does not change chaotically even if the ON time is changed chaotically. Therefore, changing the ON time chaotically with reference to the zero volt point is useful for accurately changing the rotation of the motor chaotically.
[0045]
【Example】
A first embodiment of the present invention will be described with reference to FIGS. In FIG. 1, reference numeral 11 denotes a main body, and the upper portion of the main body 11 is covered with a lid 12 so as to be opened and closed. Reference numeral 13 denotes a pan case for cooking by putting bread and kneading ingredients. The pan case 13 is heated by a heater 14. Reference numeral 15 denotes a rotating wing that is rotatably arranged on the inner bottom of the pan case 13. The rotating wing 15 kneads a material such as bread. Reference numeral 16 denotes a motor for rotating the rotary blade 15; 17, a drive circuit for controlling energization of the motor; 10, a chaos signal generating means for generating a chaos signal; and 18, a signal to the drive circuit 17 according to the output of the chaos signal generating means 10. Is a control means for sending.
[0046]
Next, an example of the chaos signal generating means 10 will be described. As an example of a function that generates a chaotic signal, there is a function shown below.
[0047]
F (X) = 2 × X (0 ≦ X <0.5)
F (X) = 2 × (1-X) (0.5 ≦ X ≦ 1)
The above formula is shown in the graph of FIG. A method of generating a chaotic signal will be described using the graph of FIG. That is, when the initial value A is calculated as the X value of F (X), F (X) = X1. This X1 is calculated again as the X value of F (X). This result is F (X) = X2, and this X2 is again calculated as the X value of F (X) to obtain a result of F (X) = X3. When the above calculation is repeated N times, X1, X2, X3,... X (N) can be obtained. That is, it is known that X (n) obtained by repeating the above calculation changes chaotically, and the data X (n) can be used as a chaotic signal. Since the conversion of FIG. 2 is the same as the movement when kneading a pie uniformly, it is generally called a pie-cone conversion and has orbital instability that does not take the same state twice.
[0048]
A specific configuration of the chaos signal generating means will be described with reference to FIG. In FIG. 3, reference numeral 30 denotes an initial value input means, which outputs an initial value A to the function calculation means 31 as an X value. The function calculation means 31 calculates the function F (X) with X = A, and outputs the calculation result as a chaos signal. The calculation result of the function calculation means 31 is stored in the storage means 32, and the stored value is input again as the X value of the function calculation means 32. Reference numeral 33 denotes an occurrence number comparing means for stopping the operation of the function calculating means 31 when the number of times calculated by the function calculating means 31 reaches a predetermined value.
[0049]
The operation of the chaos signal generating means will be described with reference to FIG. First, n = 0, the initial value X0 of the function F (X) is A, and the initial value of the number of times N is B (steps 41 to 43). Next, F (X) is calculated, and the calculation result is stored as the next X value of F (X), that is, Xn + 1 (step 44). Next, 1 is added to the value of n (step 45), and it is determined whether or not this n value has reached the initially set number N (step 46). If not reached, the above steps 44 to 46 are repeated, and if reached, the program is terminated.
[0050]
The chaos signal of the chaos signal generating means changes as shown in FIG. If the rotation of the motor is controlled using this chaos signal, the convection path of the object to be cooked is changed during the rotation cooking such as stirring, kneading, kneading and cutting of the object to be cooked. Since it has orbital instability such that it does not become the same state, if the rotation of the motor is controlled by the chaotic signal, the convection path can be changed irregularly as described above, and the uniformity of the object to be cooked can be improved.
[0051]
Although the function F (X) is used in the chaotic signal generating means, a function capable of generating a chaotic signal other than this function, such as a Bernoulli function, may be used, or a chaotic signal may be generated by an electric circuit. In short, what is necessary is that it can generate a chaotic signal.
[0052]
Next, a specific circuit configuration of the cooking device will be described with reference to FIG. As shown in the figure, the motor 16 is connected to an AC power supply via a drive circuit 17. The drive circuit 17 is a circuit composed of a triac, a transistor, and a resistor. The drive circuit 17 can turn on / off the motor 16 and determine the rotation direction. That is, the drive circuit 17 changes the on / off time of the motor 16 to control the rotational force of the motor 16.
[0053]
The microcomputer 19 outputs a control signal to the drive circuit 17 from the output ports O1 and O2. The microcomputer 19 constitutes the chaos signal generating means 10 shown in FIG. Note that reference numeral 20 in FIG. 6 denotes a DC power supply circuit for supplying power to a circuit such as the microcomputer 19 that requires a DC power supply.
[0054]
Next, the operation of the control means 18 during cooking will be described. First, the user puts powder and water, which are predetermined dough materials, into the bread case 13 and starts kneading with a kneading start switch (not shown). The operation of the control means 18 in the kneading process will be described with reference to FIGS. FIG. 7 is a block diagram showing the configuration of the control means 18, wherein 71 is a reading means for reading the output of the chaos signal generating means 10, 72 is a counter, 73 is a reset means for resetting the counter 72, 74 is an ON time determining means, 75 Is an OFF time storage means for storing the OFF time, 76 is a signal output means for outputting a signal to the drive circuit 17, 77 is a cooking timer for measuring the kneading cooking time, and 78 is an ON / OFF for measuring the ON time and the OFF time. It is an OFF timer.
[0055]
With this configuration, the control means 18 controls the ON / OFF time of the motor with the algorithm shown in FIG. In step 81, the reset means 73 sets an initial value 1 in the counter 72. In step 82, the reading means 71 reads the nth number X (n) of the chaos number sequence from the chaos signal generating means 10 as the ON time ton according to the number n stored in the counter 72. In step 83, the signal output means 76 outputs an ON signal, and in step 84, waits until ton seconds elapse according to the timing of the ON / OFF timer 78. Thereafter, the signal output means 76 outputs an OFF signal in step 85, and waits until the OFF time toff seconds stored in the OFF time storage means 75 elapses in step 86 according to the timing of the ON / OFF timer 78. The cooking timer 77 counts down the remaining time of the kneading process. If the remaining time of the cooking timer 77 is not 0 in step 87, the counter 72 increments n by 1 (step 88) and repeats step 82 and subsequent steps.
[0056]
Thus, by repeating steps 82 to 88 until the end of the kneading process, the ON time of the motor 16 can be changed according to the output of the chaos signal generating means 10, and the torque of the rotary blade 15 can be changed. Therefore, it is possible to perform kneading with a chaos signal. If the remaining time of cooking timer 77 is zero in step 87, kneading cooking is terminated. Thereafter, the user ferments the bread if it is bread, and takes out the dough that has been kneaded and cooked if it is udon or the like.
[0057]
Thus, according to the present embodiment, the rotation state of the motor is changed by the chaos signal, and the mixture is stirred, kneaded, and kneaded. Therefore, stirring, kneading, and kneading can be performed with an irregular path of movement of the cooking object, and the uniformity of the cooking object can be improved. In addition, by changing only the ON time of the motor rotation by the chaos signal and making the OFF time constant, it is possible to perform mixing, kneading, kneading, and cutting cooking with good uniformity of the cooking object with a simple program.
[0058]
A second embodiment of the present invention will be described with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. In FIG. 9, reference numeral 21 denotes an adding means for adding the chaos signal of the chaos signal generating means 10 and the rotation state output of the rotation state output means 100, which is an example of a synthesis means for synthesizing the so-called chaos signal and the rotation state. Reference numeral 22 denotes a storage means for storing the cooking process, which is configured to output a rotation state corresponding to the cooking process to the rotation state output means. Reference numeral 90 denotes a second control means that controls the drive circuit 17 by a signal from the adding means 21 to control the rotation of the motor 16. 98 is a menu input means for the user to input a menu, 99 is a selection means for selecting a cooking process from the storage means 22 in response to an input from the menu input means 98, and 101 is a start key for starting cooking. In this embodiment, the adding means 21, the storage means 22, the second control means 90, the selection means 99, and the rotation state output means 100 are realized by a microcomputer.
[0059]
Next, the case where bread is produced with the cooker having the above-described configuration will be described. That is, at the time of cooking, the user puts powder and water, which are predetermined bread ingredients, into the bread case 13, turns on the power, selects a menu, and starts cooking. This flow is shown in FIG. In step 110, the input of the menu input means 98 is waited, and when input, the cooking menu m is read in step 111. m is a number representing a menu such as bread, French bread, soft bread, etc. For example, 1 is bread, and 2 is French bread. In step 112, the process waits for the start key 101 to be pressed. When the start key 101 is pressed, the selection means 99 selects the cooking process of the menu m from the storage means 22 and the process (m) in step 113.
[0060]
FIG. 11 shows a bread manufacturing cooking process of the bread menu. The bread production process is roughly divided into three steps: a kneading step, a fermentation step, and a baking step. The kneading process is a process in which the ingredients are uniformly mixed and kneaded to make the bread dough smooth and easy. The fermentation process is a process in which the dough is kept at the temperature at which the yeast works and fermented, and the dough is finely ground by degassing during the fermentation. The baking process is a process of heating and baking the dough. The storage means 22 stores the temperature and the strength of rotation shown in FIG. 10 according to the elapsed time after the start of cooking.
[0061]
In step 114 of FIG. 10, the rotation state output unit 100 reads the rotation process (m) representing the rotation state of the process (m). After this, actual cooking is performed according to this process (m), and the bread of the selected menu is baked.
[0062]
Next, the operation of the kneading process will be described. The kneading process proceeds according to the strength of rotation by the rotation process (m). The optimum strength of kneading varies depending on the condition and temperature of the food to be cooked in the process. For example, as shown in the pre-kneading step of FIG. 11, at the start of kneading, for example, a weak rotation is performed for 3 minutes. This is because at the start of kneading, the food to be cooked is in a state of powder and water, so if a strong rotation is applied, the powder will scatter and leave unmixed powder. After the powder and water are gathered, knead for a while, for example, 3 minutes 30 seconds, in order to mix the dough firmly, but after that, perform weak kneading, for example, 13 minutes to suppress the temperature rise of the dough due to rotation. . The rotation process (m) is a data string representing the strength of kneading for each time as a motor ON time within a predetermined time, that is, a duty.
[0063]
Next, the operation of the kneading process of the adding means 21 will be described with reference to FIGS. In FIG. 12, 91 is a chaos reading means for reading the chaos signal of the chaos signal generating means 10, 92 is a rotation reading means for reading the strength of rotation from the rotation state output means 100, and 93 is storing the chaos addition gain. Gain storage means. 94 is an arithmetic means for inputting the outputs of the chaos reading means 91 and the gain storage means 93, and 95 is an n reading means for reading the number n of chaos cycles. The chaos reading is performed based on the number of cycles n output from the n reading means 95. Means 91 reads the chaos signal. 96 is a cooking timer reading means, and 97 is an output means for outputting the calculation result of the calculation means 94 to the second control means 90.
[0064]
Next, the configuration of the second control unit 90 will be described. The W input unit 120 that reads the output W of the addition unit 21 outputs the output W to the OFF time calculation unit 121 and the signal output unit 76. The OFF time calculation unit 121 calculates the OFF time from W of the W input unit 120. The counter 72, reset means 73, signal output means 76, cooking timer 77, and ON / OFF timer 78 have the same functions as in the first embodiment.
[0065]
When the strength of the kneading is W1, that is, for example, when the ON time for 5 seconds is W1 seconds and the OFF time is (5-W1) seconds, the adding means 21 outputs the chaos signal from the chaos signal generating means 10 described above. This is added to the output W1 output from the storage means 22 and output as shown in FIG. In step 121, the n reading means 95 reads the chaos cycle number n from the counter 72 of the second control means 90. In step 122, the chaos reading means 91 reads the nth, X (n) of the chaos sequence from the chaos signal generating means 10. In step 123, the cooking timer reading means 96 reads the time elapsed after the start of cooking from the cooking timer 77 of the second control means 90, and in step 124, the rotation reading means 92 determines the rotation intensity W1 according to the elapsed time after cooking. Is read from the rotation state output means 100. In step 125, the calculation means 94 calculates as shown in the figure using the gain G stored in the gain storage means 91 to obtain the rotation strength W. In step 126, the output means 97 outputs the rotation strength W to the second control means 90. The chaotic signal K by the chaos signal generating means 10 has a magnitude from 0 to 1.
[0066]
By calculating as shown in the figure, it is possible to obtain the fluctuation of the amplitude obtained by multiplying W1 by the gain with W1 as the center. At this time, the OFF time is (5-W) seconds. Since the duty cycle is 5 seconds, the maximum ON time is 5 seconds.
[0067]
Next, the operation of the second control means 90 in the kneading process will be described with reference to FIGS. In the configuration of FIG. 12, the second control means 90 controls the motor ON / OFF time with the algorithm shown in FIG. In step 140, the reset means 73 sets the initial value 1 to the counter 72. In step 141, the W input unit 120 inputs the ON time W from the output unit 97 of the adding unit 21. In step 142, the signal output means 76 outputs an ON signal, and in step 143, waits until W seconds elapse according to the time count of the ON / OFF timer 78. Thereafter, the signal output means 76 outputs an OFF signal at step 144, and waits until the OFF time (5-W) seconds calculated by the OFF time calculation means 121 elapses according to the timing of the ON / OFF timer 78 at step 145. The cooking timer 77 counts down the remaining time of the kneading process. If the remaining time of the cooking timer 77 is not 0 in step 146, the counter 72 increments n by 1 (step 147) and repeats step 141 and subsequent steps.
[0068]
In this way, by repeating steps 141 to 147 until the end of the kneading process, the ON time of the motor 16 can be changed according to the output of the chaos signal generating means 10, and the torque of the rotary blade 15 can be changed. Therefore, it is possible to perform kneading with a chaos signal. If the remaining time of cooking timer 77 is zero in step 87, kneading cooking is terminated. After the kneading process is completed, baking is performed according to the cooking process of FIG. 11 as described above.
[0069]
As described above, according to this embodiment, the rotation change by the chaos signal is obtained based on the rotation state of the motor according to the cooking process. Therefore, stirring, kneading, and kneading can be performed while maintaining the motor rotation state set according to the cooking process while changing the motor rotation in order to improve the uniformity of the object to be cooked.
[0070]
Moreover, it is possible to perform stirring, kneading, and kneading while suppressing the scattering of the food to be cooked by performing weak rotation in a state of powder or the like until the food to be cooked is mixed at the start of cooking.
[0071]
In addition, hold down the splatter of the food to be cooked at the start of rotary cooking, and then stir, knead and knead thoroughly, and then stir, knead and knead to reduce the strength of the rotation so that the temperature of the food will not rise. Cooking can be done.
[0072]

The operation of the third control means 28 during cooking will be described. The third control means 28 outputs the magnitude of the motor power as a control signal to the drive circuit 27 according to the output of the chaos signal generation means 50, and then rotates the motor 26. The motor 26 rotates the rotary blade 25 to cut vegetables and the like that are to be cooked. In general, when cutting vegetables with a rotary cooker, it is known that changing the rotational force rather than cooking with a constant rotational force cuts the vegetables etc. cleanly and uniformly without collapsing. ing. Accordingly, by performing cutting cooking with non-uniform rotational force by cutting cooking with a chaotic signal, uniform cutting cooking with little damage to the tissue of the object to be cooked can be performed.
[0078]

[0079]
A fourth embodiment of the present invention will be described with reference to FIG. Note that the same components as those in the third embodiment are denoted by the same reference numerals, and the description thereof is omitted. In FIG. 17, reference numeral 170 denotes a synthesizing unit that synthesizes a chaos signal with the output of the rotation state output unit 100. 177 is a drive circuit for controlling the energization of the motor 26, 171 is a fourth control means for sending a control signal to the drive circuit 177 in accordance with the output of the synthesizing means 170, and 174 is a comparison for comparing the output of the rotation state output means 100 with a predetermined value.

[0081]
When cooking with the cooker having the above-described configuration, the user puts the cooking material into the container 23, turns on the power, inputs the menu or material using the menu switch 175 or the material switch 176, and starts cooking.

When cooking is started by the start switch 178, the second selection means 172 reads the input a of the menu switch 175 in step 181 and reads the input b of the material switch 176 in step 182. In step 183, the second selection unit 172 selects the rotary cooking process and the rotation process (a, b) according to a and b from the second storage unit 173. For example, if a is 0, the menu indicates no input, and 1 is “make hamburger seeds from block meat and vegetables”. When b is 0, no material is input, 1 is “vegetable”, 2 is “fish”, and 3 is “meat”. Therefore, (a, b) = (0, 2) means cooking to make fish tsunami, and (1, 0) means cooking to make hamburger seeds from block meat and vegetables.
[0082]
FIG. 20 shows a rotation process (1, 0) and a rotation cooking process for making hamburger seeds from block meat and vegetables. When making hamburger seeds from block meat and onion, at the start of cooking, the food to be cooked is a lump because it is a lump with strong rotational force, but as the meat and onion become finer, the rotational force is weakened and kneaded. In addition, when cooking with fish, if the rotational force is too strong, the temperature rises due to friction and the taste becomes poor, so the rotational force is not so strong.

In FIG. 21, reference numeral 201 denotes second calculation means for inputting signals from the chaos reader 91, the rotation reading stage 92, and the gain storage means 93. The calculation result is sent to the fourth control means 171 via the T output means 203. It is the structure which outputs. The chaos reading means 91, the rotation reading means 92, the gain storage means 93, the n reading means 95, and the cooking timer reading means 96 have the same functions as in the second embodiment.
[0084]

The counter 72, the reset means 73, the cooking timer 77, and the ON / OFF timer 78 have the same functions as in the second embodiment.
[0085]
When the intensity of rotation, which is the output of the rotation state output means 100, is T1, that is, when the ON time during a half cycle of the commercial power source is T1 seconds, the combining means 170 according to the comparison result of the comparison means 174. Adds the chaotic signal from the chaotic signal generating means 10 described above to T1 and outputs it as shown in FIG. In step 221, the n reading means 95 reads the number n of chaos cycles from the counter 72 of the fourth control means 171. In step 222, the chaos reading means 91 reads the nth, X (n) of the chaos sequence from the chaos signal generating means 50. In step 223, the cooking timer reading means 96 reads the time elapsed after the start of cooking from the cooking timer 77 of the fourth control means 171. In step 224, the rotation reading means 92 reads the rotation strength T1 corresponding to the elapsed time after cooking. Is read from the rotation state output means 100.
[0086]
In step 225, the second calculation unit 201 examines the comparison result of the comparison unit 174. The comparison means 174 compares T1 with a predetermined value Tth and outputs 1 when T1> Tth and 0 when T1 ≦ Tth. When the comparison result is 1, the second calculation means 201 performs the calculation as in step 226 using the gain G stored in the gain storage means 93, and when the comparison result is 0, the calculation T = T1 in step 228. And In step 227, the T output means 203 outputs the rotation strength T to the fourth control means 171.
[0087]
Next, the operation of the fourth control means 171 will be described with reference to FIGS. In the configuration of FIG. 21, the fourth control means 171 controls the motor ON / OFF time by the algorithm shown in FIG. In step 230, the reset means 73 sets an initial value 1 in the counter 72. In step 231, the T input unit 202 inputs the ON time T from the T output unit 203 of the combining unit 170. The cooking timer 77 counts down the remaining cooking time. If the remaining time of the cooking timer 77 is not 0 in step 232, the process proceeds to step 233. If the remaining time is 0, the cooking ends. Step 233 is a step of waiting for the zero volt cross of the power source, and the second signal output means 178 waits until the zero volt detecting means 179 detects zero volt. When zero volt is detected, the second signal output means 178 outputs an ON signal in step 234, and waits until T seconds elapse according to the timing of the ON / OFF timer 78 in step 235. Thereafter, in step 236, the second signal output means 178 outputs an OFF signal, and in step 237, the counter 72 increments n by 1 and repeats step 231 and subsequent steps.
[0088]
Thus, by repeating steps 231 to 237 until the end of the kneading process, the motor 26 is turned on when the power source becomes zero volts as shown in FIG. 24, and the subsequent ON time is changed according to the output of the chaos signal generating means 50.
