Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) First, the configuration of a cooking navigation system according to Embodiment 1 of the present invention will be described.

FIG. 1 is a block diagram showing a cooking navigation system according to the first embodiment of the present invention. As shown in FIG. 1, the cooking navigation system according to the first embodiment includes:
Input means 1, control means 2, recipe data storage means 3
Search / readout means 4, accumulated time calculation means 5,
It comprises a cooking procedure determining means 6, a navigation means 7, and an output means 8.

The input means 1 is a means for a user to input a request or an instruction. The control means 2 is a search / readout means 4 based on the user's request or an instruction received by the input means 1. It is a means for controlling the operations of the time calculating means 5, the cooking procedure determining means 6, the navigation means 7, and the output means 8.

The recipe data storage means 3 is a means for storing recipe data of a plurality of dishes. The recipe data of each dish includes cooking steps immediately before or after each of the plurality of cooking steps of the dish. The data includes a tree-structured data and cooking time data for each cooking process.
The tree structure will be further described with a specific example when the operation of the cooking navigation system according to the first embodiment is described later.

The search / read means 4 is means for searching and reading the designated data from the data stored in the recipe data storage means 3 under the control of the control means 2. The cumulative time calculating means 5 performs, for each cooking step, from each cooking step to the completion of the dish based on the tree structure data read by the search / reading means 4 and the cooking time data of each cooking step. This is a means for calculating an accumulated time obtained by accumulating the cooking times of.

The cooking procedure determining means 6 is a means for determining a cooking procedure when the user performs each cooking step, using the cumulative time for each cooking step calculated by the cumulative time calculating means 5. The cooking procedure determining means 6 also has a function of modifying the determined cooking procedure so as to shorten the overall cooking time. The navigation means 7 is means for instructing the timing of performing each cooking step in accordance with the cooking procedure determined or corrected by the cooking procedure determination means 6, and the output means 8 is configured to output each of the cooking instructions designated by the navigation means 7. This is means for outputting the timing of performing the cooking process using sounds and images.

Next, the operation of the cooking navigation system according to the first embodiment of the present invention will be described with reference to the flowchart of FIG.

For the sake of convenience in the following description, it is assumed that the user wants to know each cooking step and an efficient cooking procedure when cooking a dish called “lyonnaise”.
Then, an instruction to inform each of the cooking steps of "Lyonase" and an efficient cooking procedure is input (step 1 in FIG. 2). Further, for convenience of explanation, it is assumed that the user intends to cook for a standard number of people (for example, four people).

Then, the control means 2 controls the operation of the search / read means 4 based on the user's instruction received by the input means 1, and the search / read means 4 operates in accordance with the control. Then, the recipe data of "Lyonase" is searched and read out from the data stored in the storage device 3 (step 2 in FIG. 2).

Here, the data of the tree structure in the recipe data of "Lyonaise" will be described with reference to FIG. As shown in FIG. 3, the cooking ingredients of “Lyonades” are broccoli M1, pumpkin M2, and soup M3.
Water M4, salt and pepper M5, bread crumbs M6, onion M7, bacon M8, and garlic M9.
Note that “NX” (X = 0 to 22) in FIG. 3 is a node indicating a cooking unit. In addition, the required amount of each cooking material of “Lyonase” for four persons is defined as shown in Table 1, and the information also corresponds to a part of the recipe data.

[0045]

[Table 1] Now, regarding FIG. 3, focusing on broccoli M1,
As shown in FIG. 3, the user first cooks by cutting “N12”. Next, paying attention to the pumpkin M2, after cooking "N11" is warmed, cooking "N10" is cut. As described above, the tree structure shown in FIG. 3 indicates that, when attention is paid to the pumpkin M2, the cooking of "N10" should be performed after the cooking of "N11" to be heated.

Next, focusing on the water M4, after cooking "N9" to boil, add the soup M3 to the boiled water M4 ("N8"), and then put "N10" in it.
The tree structure shows that it is necessary to cook the pumpkin M2 cut at "N7" and cook the broccoli M1 cut at "N12" therein and then cook ("N6"). .

In the tree structure, after the cooking process of boiling "N6", the cooking process of transferring the cooked food to the "N5" colander and further to the heat-resistant container ("N4") should be performed. Is shown.

Next, focusing on salt and pepper M5, bread crumbs M6, onion M7, bacon M8, and garlic M9, the tree structure is as follows. ), Onion M7 and bacon M8, respectively, "N2
0 "and" N19 "are to be cut.

In the tree structure, in the cooking step involving garlic M9, after cooking "N18", cooking "N17" is fried, and the bacon cut in "N19". Add M8 and fry ("N16"), then add onion M7 cut in "N20" and fry ("N15"), then "N2"
1), add the fried bread crumbs M6 and fry (“N1
4 ”), then add salt and pepper M5 and fry (“ N1
3 ").

Then, in "N3", in a heat-resistant container to which broccoli M1 and the like were transferred in the cooking process of "N4",
Place onion M7 or bacon M8 fried in "N13", then bake in the oven in "N2" and serve it on a plate ("N1") to complete a dish called "lyonase"("N0") This is shown in the tree structure.

As described above, the tree structure indicates cooking steps to be performed immediately before or immediately after each cooking step. However, when attention is paid to the cooking of cutting “N12” and the cooking of heating “N11”, information on which one should be first is not included in the tree structure. That is, the order of cooking steps connected in series is determined, but the order of cooking steps not connected in series is not determined.

It should be noted that "A" in FIG.
Indicates that it is necessary to continuously perform the cooking process of the node marked with and the next cooking process. Specifically, if the cooking step of adding “N8” is performed, then the cooking step of boiling “N7” must be performed, and the cooking step of “N8” is followed by “N20”. This indicates that a cooking process other than “N7” such as a cooking process of cutting must not be performed.

Next, the cooking time of each cooking step in the recipe data of "lyonise" read by the search / read means 4 will be described with reference to Table 2. Note that the cooking time of each cooking step in Table 2 indicates a cooking time when cooking for a standard number of people (for example, four people).

[0054]

[Table 2] Each node in Table 2 is the same as the node with the same number in FIG. Now, the cooking time of each cooking step is, as shown in Table 2, the total time of the working time and the leaving time. Here, the working time means the time when the user actually works and the hands are restrained, and the leaving time is, for example, the case where the water in the pot is boiled by heating or the case where the boiling water is used. As described above, it means the time when the user does not work and the hand is not restrained.

With reference to Table 2, several cooking steps will be described and the cooking time of the cooking steps will be described. As a specific example,
When "warming" of "N11" is taken up, the working time is 30 seconds, the leaving time is 330 seconds, and "N1"
It can be seen that the cooking time of the cooking step of “1” “warm” is 360 seconds. As another specific example, taking "fried" of "N17", the working time is 45 seconds,
Since the leaving time is 0 second, it can be seen that the cooking time of “fry” of “N17” is 45 seconds.

Note that “association” in Table 2 means a node of a cooking process immediately before the corresponding cooking process in the tree structure, and “continuity” is performed immediately after the corresponding cooking process. This indicates whether there is a cooking process to be performed.

Next, based on the tree structure data of FIG. 3 and the cooking time data of each cooking step in Table 2, the cumulative time calculating means 5 calculates the number of dishes from each cooking step for each cooking step. An accumulated time obtained by accumulating the cooking time of each cooking process until completion is calculated (step 3 in FIG. 2). Table 3 shows the calculated cumulative time for each cooking process. The accumulated time is displayed in the rightmost column of Table 3.

[0058]

[Table 3] Describing by giving a specific example, the cumulative time of the cooking process of “bake” of “N2” is the cooking time of “N2” in Table 2 and the cumulative time of “N2”.
The total of the cooking time of the cooking process of “N1” to be performed after the cooking process of “2” and the cooking time of the cooking process of “N0” is 390 seconds. Similarly, the cumulative time of the cooking process of “fried” of “N15” is calculated by the cooking time of “N15” in Table 2 and the “N” to be sequentially performed after the cooking process of “N15”.
14 "," N13 "," N3 "," N2 "," N1 ",
The total of the cooking time of each cooking process of “N0”,
0 seconds. Note that Table 3 also includes the information shown in Table 2.

Incidentally, when calculating the cumulative time, the cumulative time calculating means 5 performs the calculation of the continuous group before any one of the continuous steps composed of a plurality of cooking steps which need to be continuously performed. When performing a cooking process other than the cooking process, when calculating the cumulative time for the cooking process other than the cooking process of the continuous group, the cooking time of the cooking process is added to the cumulative time for the first cooking process in the order of the continuous group. The time obtained by adding the time is the accumulated time.

For example, the cumulative time of the cooking process of “cut” of “N10” is not the time obtained by adding the cooking time of “N10” to the cumulative time of the cooking process of “boil” of “N7”, but
"N1" is added to the cumulative time of the cooking process of "boil" of "N9".
This is the time obtained by adding the cooking time of “0”.

Next, the cooking procedure determining means 6 determines the cooking procedure in descending order of the cumulative time by using the cumulative time for each cooking step described with reference to Table 3 (Step 4 in FIG. 2). . Table 4 shows the determined cooking procedure.

[0062]

[Table 4] Next, the cooking procedure determining means 6 corrects the determined cooking procedure as shown in Table 4 so that each cooking step in a continuous group composed of a plurality of cooking steps that need to be performed continuously is continuous. (Step 5 in FIG. 2). Table 5 shows the modified cooking procedure.

[0063]

[Table 5] By the way, for example, the cooking time of the cooking process of “warming” of “N11” in FIG. 3 includes the leaving time as shown in Table 2, but in the cooking procedure shown in Table 5, the cooking time of the It cannot be used effectively. That is,
The leaving time of “N11” is 330 seconds, and since the user does not work for that 330 seconds, it is possible to cook “N12” or cook “N20”. In the cooking procedure shown in Table 5,
The idle time does nothing. Paradoxically, it is possible to effectively use the idle time.

Therefore, the cooking procedure determining means 6 selects one or more cooking steps to be performed after the cooking step having the standing time in Table 5 since the total of the cooking time or the working time falls within the leaving time. Then, the cooking procedure shown in Table 5 is corrected again so that the selected cooking process is performed within the idle time. In such a case, there is an advantage that the entire cooking time until completion of the dish is shortened. Table 6
Fig. 7 shows a cooking procedure in consideration of the standing time.

[0065]

[Table 6] When the cooking procedure is modified in consideration of the idle time, the cooking procedure determining means 6 is composed of a plurality of cooking steps that need to be continuously performed when selecting a cooking step to be performed within the idle time. Do not select only some cooking steps in a continuous group. This is because if only some of the cooking steps are selected, there is a possibility that the cooking steps to be performed continuously cannot be performed continuously. However, it is possible to select all cooking steps in a continuous group. In addition, the cooking procedure determining means 6 corrects the cooking procedure without changing the order of the cooking steps connected in series.

In accordance with the cooking procedure corrected and finally determined by the cooking procedure determining means 6, the navigation means 7 determines the cooking process to be cooked by the user with the lapse of time from the start time instructed by the user. The output unit 8 is instructed to perform the operation, and the output unit 8
The timing at which each of the designated cooking steps is to be performed is output using sounds and images (step 6 in FIG. 2).

As described above, by using the cooking navigation system according to the first embodiment of the present invention, the user can cook in the shortest cooking time and can cook the food deliciously.

When the output means 8 navigates the cooking procedure using sounds and images, a response from the user as to whether or not each cooking step has been completed within the designated time is provided.
The cooking navigation system may receive the information via the input unit 1. Then, when the user can perform each cooking step within the designated time, the output means 8 navigates the finally determined cooking procedure, and on the other hand, within the designated time, If the cooking step could not be performed, the cooking procedure determining means 6 may correct the cooking procedure again. When the progress of the user is used in this way, the cooking procedure is modified according to the user's cooking ability, so that the user can cook according to the procedure according to his / her own cooking ability.

In the above-described embodiment, the cooking procedure determining means 6 determines the cooking procedure in descending order of the accumulated time, for example. However, the cooking procedure may be determined by another method. For example, the cooking procedure may be determined so that the same type of cooking content is continuous. Specifically, "N
This means that the cooking procedure may be determined so that the cooking step of cutting “12” and the cooking step of cutting “N20” are continuous. In short, the cooking procedure determining means 6
Only needs to determine or correct the cooking procedure using the cumulative time calculated by the cumulative time calculating means 5.

In the above-described embodiment, when the cooking procedure is corrected in consideration of the leaving time, the cooking procedure determining means 6 determines one or more cooking steps to be performed after the cooking step having the leaving time. Although the selection has been made, one or a plurality of cooking steps which are not in a serial relationship with the cooking step having the standing time may be selected. That is, the cooking process of another branch branched in the tree structure may be selected.

However, also in this case, without changing the order of the cooking steps connected in series, only some of the cooking steps in a continuous group consisting of a plurality of cooking steps that need to be performed continuously are not selected. You need to do that.

Although not described in the above-described embodiment, if there are a plurality of cooking steps in which the difference between cooking times falls within a predetermined time, the cooking procedure determining means 6 sets the cooking procedure to the same type of cooking content. If there is a possibility that the steps can be continued, the cooking procedure may be determined or modified so that cooking steps of the same type of cooking content are consecutive. When there are a plurality of cooking steps in which the difference between the cooking times falls within the predetermined time, the cooking procedure determining means 6 may determine or correct the cooking procedure in the order of the longest or shortest cooking time. Then, the cooking procedure may be determined or modified so that the cooking steps belonging to the intermediate cooking group for cooking the same intermediate unfinished food are continuous.

For example, when cooking “lyonise”,
Broccoli M1, pumpkin M2, soup M3,
A cooking process belonging to an intermediate cooking group for cooking an intermediate unfinished food cooked with water M4 is continuous, during which cooking with salt and pepper M5, bread crumbs M6, onion M7, bacon M8, and garlic M9. The cooking procedure determining means 6 may determine or correct the cooking procedure so that the cooking steps belonging to the intermediate cooking group for cooking the intermediate unfinished food to be performed are not sandwiched.

When the cooking procedure is determined or corrected, the cooking procedure determining means 6 needs to determine or correct the cooking procedure without changing the order of the serially connected cooking steps in the tree structure shown in FIG. There is.

Further, input means 1 in the above-described embodiment may be a touch panel, or may be a means for receiving an instruction by voice input or key input.

In the above-described embodiment, the recipe data storage means 3 is provided in the cooking navigation system. However, the recipe data storage means 3 may not be provided in the cooking navigation system. . In this case, the search / readout unit 4 may read the recipe data using, for example, the Internet.

The user is allowed to select in advance whether to request a detailed navigation or to skip the contents of the cooking procedure to be navigated by the output means 8 according to the selection. The navigation means 7 and / or the output means 8 may perform navigation.

(Embodiment 2) Next, a cooking navigation system according to Embodiment 2 of the present invention will be described.

The configuration of the cooking navigation system according to the second embodiment is the same as the configuration of the cooking navigation system shown in FIG. 1, but the operation thereof is partially different. The differences will be described.

In the first embodiment, the user tries to know the cooking process of “lyonase” and the efficient cooking procedure, whereas in the second embodiment, the user selects “lyonase” and “saute mackerel”. And the efficient cooking procedure. Then, it is assumed that the user inputs to the input means 1 an instruction to inform the cooking process of “ryonise” and “sauteed mackerel” and the efficient cooking procedure.

Then, as in the first embodiment, the search / read means 4 operates according to the control of the control means 2.
From among the data stored in the recipe data storage means 3, the recipe data of "Lyonaise" and "Sauteed mackerel" are searched and read. Here, FIG. 4 shows “sauteed mackerel”
And the tree structure of "Lyonase". Note that the tree structure of the “lyonise” portion is the same as that of FIG.
In addition, it is assumed that the tree structures of both “sauce of mackerel” and “lyonise” are related.

Next, as in the first embodiment, the cumulative time calculating means 5 calculates the cumulative time for each of the cooking steps for “Lyonades”, as in the first embodiment, for each of “Lyonades” and “sauteed mackerel”. The cumulative time for each cooking process is calculated. Describing the calculation again, the cumulative time calculation means 5 determines each of the cooking processes to be performed before and after each of the cooking processes shown in the tree structure and the cooking time data of each of the cooking processes of each of the dishes. For each cooking process, an accumulated time obtained by accumulating the cooking time of each cooking process from each cooking process to completion of the dish is calculated. Table 7 shows the cooking time of each cooking process, the calculated accumulated time for each cooking process, and the like.

[0083]

[Table 7] Then, the cooking procedure determining means 6 first determines cooking procedures in descending order of the cumulative time by using the cumulative time for each cooking process calculated by the cumulative time calculating means 5, and then needs to continuously perform the cooking procedures. The previously determined cooking procedure is corrected so that each of the cooking steps in the continuous group including a plurality of cooking steps having the following is continuous. Further, the cooking procedure determination means 6 further utilizes the leaving time to further modify the cooking procedure so that the entire cooking time until completion of the dish is shortened.
Table 8 shows the finally determined cooking procedure.

[Table 8] In this way, when the user cooks according to the finally determined cooking procedure, “lyonise” and “sauteed mackerel” can be efficiently completed.

In the example described with reference to the tree structure and Tables 7 and 8 shown in FIG. 4, "Lyonaise" is completed first, "Saba saute" is completed later, and "Saba saute" is completed. Can be eaten freshly baked. In other words, the above example is an example of a case in which “saute of mackerel” is higher in consideration of the completion priority, which is information on which dish is to be completed later,
The completion priority may be stored in the recipe data storage unit 3 in advance.

Also, the tree structure of “Lyonades”
The tree structure of “Saber Saute” is not related as shown in FIG. 4 and is independent, and the completion of “Saber Sauce” should be 5 minutes after the completion of “Lyonaise”. When the user thinks, the cumulative time calculating means 5
May modify the cumulative time by adding 5 minutes to the cumulative time for each cooking step of “Lyonades” based on the instruction from the user via the input means 1. In that case, the cooking procedure determining means 6 determines, based on the corrected accumulated time,
Modify the cooking procedure. By using the cooking procedure modified in this way, the completion of “saute of mackerel” is 5 minutes after the completion of “lyonase”, and the “saute of mackerel” and “lyonise” are completed according to the user's preference. .

Further, in the above-described embodiment, the cooking procedure for cooking a plurality of dishes has been described by taking “saute of mackerel” and “lyonase” as an example, but “saute of mackerel” and “lyonise” In addition to the case where two types of dishes are cooked as described above, the cooking procedure when three or more types of dishes are cooked can also be determined and corrected as described above.

When cooking a plurality of dishes of three or more types, the cumulative time calculating means 5 first calculates the cumulative time for each cooking step of each dish, and the cooking procedure determining means 6 has a large cumulative time. The cooking procedure is determined so as to be arranged in order from the cooking process, and the idle time is further effectively used so that each cooking process in a continuous group consisting of a plurality of cooking processes that need to be performed continuously is continuous. Then, the previously determined cooking procedure is corrected so that the entire cooking time until completion of the dish is shortened.

When three or more types of dishes are cooked, the cumulative time for each cooking step of each dish is calculated when the completion priority, which is information on the order of completing dishes, is determined in advance. Is determined according to the instruction, and if there is an instruction from the user as to in what order and at what time interval the user wants to complete each dish, it is determined according to the instruction.

More specifically, the cumulative time of each cooking step of a dish with a lower completion priority is a time obtained by adding a predetermined time to each cumulative time unique to the dish. Similarly, the user can complete the dish earlier. The cumulative time of each cooking process of the dish for which the instruction to the effect is desired is also a time obtained by adding a predetermined time to each cumulative time unique to the dish.

Although not described in the above-described embodiment, the cooking procedure determining means 6 determines the number and types of cooking utensils and the number and types of storage utensils for storing intermediate dishes made during the completion of cooking. The work procedure may be determined or modified in consideration of the above.

Here, an example in which the work procedure is determined or corrected based on the cooking utensils required for cooking “lyonise” described in the first and second embodiments and the cooking utensils owned by the user explain. Table 9 shows a list of cooking utensils necessary for cooking “lyonise”. Table 10 shows a list of cooking utensils owned by the user.

[0093]

[Table 9]

[0094]

[Table 10] A list of cooking utensils necessary for cooking "Lyonaise" shown in Table 9 is stored in the recipe data storage means 3, and a list of cooking utensils owned by the user shown in Table 10 is shown. Is stored in the recipe data storage means 3 through the input means 1 when the user introduces the cooking navigation system and subsequently purchases new cooking utensils. Also, in the recipe data,
It is assumed that necessary cookware is described for each cooking process (for each node).

The cooking procedure determining means 6 has a list of cooking utensils necessary for cooking "Lyonaise" in Table 9 when determining or correcting the cooking procedure, and the user in Table 10 owns the list. The cooking procedure is determined or corrected by comparing the list of cooking utensils with each other and determining whether the idle time can be effectively used. For example, when a microwave oven is used in a cooking process of a cooking time including a leaving time, and the cooking procedure is modified so that another cooking process is performed during the leaving time, the cooking procedure determining means 6 may use the electronic process. This means that the cooking procedure is modified so that a cooking process that does not use a stove is performed within the idle time.

The number of stoves greatly affects the efficiency of cooking. If the user has a plurality of stoves, there can be a plurality of steps using the stove during the idle time, and an efficient cooking procedure is determined.

[0097] The output means 8 may inform the user of the cooking utensils necessary for cooking "Lyonaise" by displaying images or outputting sounds that are not owned by the user.

Further, for example, when the user cooks “Lyonades”, he does not have broccoli, and uses cabbage instead of broccoli to “Lyonades”.
When the user desires to cook the food and inputs the fact to the input means 1, the cumulative time calculating means 5 calculates the cumulative time of each cooking process when the broccoli is replaced with cabbage. As described above, when the user is instructed to change the cooking material, the cumulative time calculating means 5 calculates the cumulative time based on the instruction. In any case, the cooking procedure determining means 6
Determines and / or corrects the cooking procedure using the cumulative time calculated by the cumulative time calculating means 5.

[0099] It should be noted that, although cooking steps may be added or deleted in accordance with a change in cooking ingredients, they may be changed.
In this case, the cumulative time calculation means 5 calculates the cumulative time taking into account the change in the cooking process. This is because, for example, when the cooking material is changed from raw shiitake mushroom to dried shiitake mushroom, a step of reconstituting water may be newly added.

For further explanation, Table 11 shows an example of a list of ingredients that can be used as alternative ingredients when cooking “Lyonaise”.

[0101]

[Table 11] In Table 11, instead of 1/6 pumpkin, potato 2
It shows that 50 g of pork slices can be used instead of 1/2 bacon. When the alternative ingredients are used in this way, a part of the cooking process and the cooking time (working time, leaving time) are changed. Table 12 shows an example of the change information.

[0102]

[Table 12] When the alternative ingredients are used, the process of “warming” of “N11” in FIG. 3 is changed to the process of “draining” of “N11”, and accordingly, the working time and the leaving time are changed. Table 3 shows that the operation time is changed for the step “cut” of “N10” of FIG. 3, but the operation time is also changed for the step “cut” of “N19” of FIG. 12 shows.

When the user is instructed to use the alternative ingredients shown in Table 11, the cumulative time calculating means 5 uses Table 12 to calculate the cumulative time for each cooking process based on the instruction. Is calculated. Further, cooking procedure determining means 6
Determines and / or corrects a cooking procedure so that cooking can be efficiently performed using the cumulative time calculated by the cumulative time calculating means 5.

The change numbers in Table 11 and Table 12
Are the numbers assigned to indicate the corresponding parts in both tables. The change number “1” in Table 11 corresponds to the change number “1” in Table 12, and the change number “1” in Table 11. "2" corresponds to change number "2" in Table 12. Tables 11 and 12 are stored in the recipe data storage unit 3.

As described above, even when all the ingredients are not prepared, the user can cook the originally planned dish by using the substitute ingredients he has, and can know the cooking procedure. Become like

When information such as how many dishes to cook from the user, whether or not it is better to fry or bake the ingredients, and the taste and the like are input, the accumulated time calculation means is provided. The cooking procedure determining means 6 and the cooking procedure determining means 6 may calculate the accumulated time and determine and / or correct the cooking procedure in consideration of the information.

Further, the cumulative time calculating means 5 and the cooking procedure determining means 6 may calculate the cumulative time and determine and / or correct the cooking procedure in consideration of the number and ability of the people who cook. Good. In addition, about ability of person to cook,
A method may be used in which the degree of kitchen knife judgment is previously tested and the test result is used.

Here, the cooking time of each cooking process, which is determined by the ability of the person who cooks and the number of people to cook, is represented by the standard number of persons shown in Table 1 (4 persons).
Table 13 shows the results of comparison with the case of cooking for minutes.

[0109]

[Table 13] In Table 13, the standard operation time, the standard leaving time, and the standard cooking time are the same as the operation time, the leaving time, and the cooking time in Table 2, respectively. The “quantity coefficient” means a number indicating the ratio of the number of people who cook to a standard number of people (four). In addition, about "quantity coefficient", regardless of how many people cook, if it takes the same time as cooking time for four people, "1"
Is described.

For example, when the “accustomed coefficient” is 1, it means that the cooking ability is standard, and when the “accustomed coefficient” is 1.2, the cooking ability is inferior to the standard person, and This means that it takes 20% more time than a standard person. Note that, depending on the cooking process, the “accustomed coefficient” is 1 even when it takes almost a fixed time regardless of the ability. Further, the fact that the “quantity coefficient” is 0.5 means that 50% of the standard number of people (four) is cooked, that is, two people are cooked. Note that, as described above, although the “quantity coefficient” is 1, the number of people who cook is two, as described above, it may mean that the cooking time is the same as when cooking four people.

More specifically, in the case of Table 13, the cook is not accustomed to the “cut” operation of “N10” or the “fried” operation of “N21”.
It takes 20% longer than a standard person, and “1.2” is assigned as the “accustomed coefficient”. As for the amount, when the standard time of the recipe data is the time required to cook the amount for 4 people, and when cooking for 2 people,
Since the number of people is 0.5 times that of four people, "quantity coefficient"
Is assigned as “0.5”.

The “cooking time” in Table 13 is
The standard cooking time is a time obtained by multiplying the “accustomed coefficient” and the “quantity coefficient”. When the cooking time shown in Table 13 is used, the cooking determined by the ability of the cook and the number of dishes to be cooked are determined. There is an advantage that the accumulated time is calculated and the work procedure is determined according to the situation.

[0113] The "accustomed coefficient" and the "quantity coefficient" indicating the cooking ability of the cook are input to the input means 1 by the cook. In addition, the “coaching factor” may be determined by the cook independently, or a test item may be prepared in advance, and the cook may test and test the item.

In addition, when a cook performs a test, only one test may be performed for a group of similar cooking processes, and the result may be used as the familiarity coefficient of all the cooking processes in the group. Table 14 shows a table defining an example of a group constituted by similar cooking steps.

[0115]

[Table 14] In Table 14, it is divided into four groups G1 to G4, and the portion where the “accustomed coefficient” is “1” indicates that it does not depend on the ability of the cook. Note that the “W” portion of the “quantity coefficient” in Table 14 indicates the ratio of the cooking amount to the standard amount, and the portion where the “quantity coefficient” is “1” indicates that the amount does not depend on the amount.

Further, the cooking navigation system includes:
The cooking procedure determined by the cooking procedure determining means 6,
Notification means for notifying the total cooking time when cooking according to the modified cooking procedure may be provided.
When the total cooking time is notified in this way, the user:
You can know how long it takes to complete a dish. The notifying means may have a function of notifying the time from the middle of the cooking process to the completion of the cooking when all the cooking processes are performed based on the determined or corrected cooking procedure. In this case, the user can know how long the food can be completed.

Further, the tree structure and the cooking time described in the first and second embodiments reflect the intention of the person who creates the data (the person who makes the recipe). Therefore, the “deliciousness” of the finished dish
Will reflect the intention of the person who made the recipe.
Therefore, if a person who is particular about “deliciousness” makes a recipe, the finished dish will be delicious.
