  However, when the number of cooking menus registered in advance increases, a call operation for a desired cooking menu becomes complicated. Therefore, as a technique for reducing the complexity of such an operation, in Patent Document 1, one or more of a plurality of cooking menus are registered in advance as a priority call menu, so that a priority call is made when the menu is called. There is disclosed a cooking device that preferentially calls and executes a cooking menu registered as a menu.

  In the technique of Patent Document 1, it is assumed that a user registers a cooking menu having a high use frequency as a “priority call menu (favorite menu)” among all registered cooking menus. At this time, the user can cook by a simple operation by selecting a desired cooking menu from the “favorite menu”.

  In such a favorite function, each time the user operates a predetermined key, registered cooking menus are sequentially called. Therefore, the user presses the execution key when a desired cooking menu is called. Thereby, cooking according to the selected cooking menu, for example, heating control, can be performed.

Patent Document 2 discloses a cooking related information providing system for selecting an appropriate cooking menu from provided cooking related information. In this system, an appropriate cooking menu is selected based on selection information indicating cooking data selected according to a preference of a cooking person, including a cooking history of a cooking device such as a microwave oven.

FIG. 5 is a flowchart showing the flow of processing when the control unit 2 learns the degree of user preference for cooking.

  In addition, the preference learning part 12 should just start the learning process shown in FIG. 5 according to a predetermined timing. For example, the learning process may be started when a predetermined time has elapsed since the last time when the learning process was performed, or when the operation receiving unit 11 receives an operation by the user.

  The preference learning unit 12 first reads the dish history information from the memory 3 (step S50). Next, for the dish (historic dish) recorded in the dish history information, information (dish characteristic information) representing the characteristics of each history dish is extracted (step S51).

  The preference learning unit 12 uses, as the cooking feature information representing the characteristics of the history cooking, cooking feature information representing the ingredients, the cooking type (Japanese food, Western food, etc.), the cooking method (range, oven, etc.), the heating time, etc. It can be suitably extracted from the information. In other words, the preference learning unit 12 includes each of the ingredients used for cooking the historical dish, the nutrients included in the historical dish, the calorie content of the historical dish, the type of historical dish, the cooking method of the historical dish, and the time required for cooking the historical dish Learn preference information for cooking feature information. The preference information may simply be the appearance frequency of each dish characteristic information, or may be a numerical value obtained using the appearance frequency. Therefore, the microwave oven 1 can more reliably determine the tendency of the user's preference for cooking, for example, what kind of material or method is preferred.

  In the microwave oven 1, tag information or meta information representing the characteristics of the history dish may be associated with the dish history information. At this time, the preference learning unit 12 extracts information representing the characteristics of the historical dish based on the tag information or the meta information associated with the dish history information.

  In addition, a keyword representing cooking characteristics may be stored in the memory 3 in advance. In this case, the preference learning unit 12 determines whether or not the keyword stored in advance in the memory 3 is included in the cooking history information by executing a character string matching process. When a keyword is included in the cooking history information, the keyword is regarded as cooking feature information.

  After extracting the cooking feature information, the preference learning unit 12 updates the preference information stored in advance in the memory 3 (step S52). Next, it is determined whether or not the cooking history information being processed is the last cooking history information (step S53).

  When the result of the determination in step S53 is “true” (YES), the processing shown in FIG. 5 ends. On the other hand, when the result of the determination in step S53 is “false” (NO), the processing shown in FIG. 5 returns to step S50. At this time, the preference learning unit 12 reads out the next unprocessed cooking history information from the memory 3. In this manner, the preference learning unit 12 repeatedly executes the processes of steps S50 to S53 until a “true” result is obtained in the process of step S53.

  As described above, the preference learning unit 12 processes, for example, the cooking history information whose dish name is “squid ink spaghetti”, cooking information such as “Ikaika”, “spaghetti”, “Italian cuisine”, etc. Cooking type information and cooking utensil information such as “range” are extracted.

  Note that “squid” representing a higher-order concept may be extracted from the cooking history information instead of “delicious” as the ingredient information. In this case, in the memory 3 of the microwave oven 1, the word “squid” is defined in advance as a superordinate concept such as “do it? What is necessary is just to identify the high-order concept of each term contained in cooking history information using this definition information.

(Example of preference information)
An example of the preference information updated by the preference learning unit 12 will be described below with reference to FIGS. FIG. 6 is a diagram showing the preference information 60 and 61 before being updated. FIG. 7 is a diagram showing the preference information 70 and 71 after being updated.

  The preference learning unit 12 generates preference information 60 and 61 and stores it in the memory 3. The preference information 60 is information in which the appearance frequency of each ingredient in the cooking history information is associated with each cooking time zone. The preference information 61 is information that associates the appearance frequency of the cooking type for each cooking time zone.

  It is assumed that the preference learning unit 12 extracts, for example, food information from the cooking history information. At this time, the preference information 60 is updated to the preference information 70 by increasing the appearance frequency of the ingredients in the preference information 60. On the other hand, it is assumed that the preference learning unit 12 has extracted information about the type of dish from the dish history information. At this time, the preference information 61 is updated to the preference information 71 by increasing the appearance frequency of the dish type.

  In this way, the preference learning unit 12 updates the history information for each time zone within the day for cooking. Note that the preference learning unit 12 can learn the preference information for each time represented by the time information included in the cooking history information. That is, the preference learning unit 12 generates preference information that associates information representing various times (cooking environment) such as days of the week and months with cooking characteristic information, as well as the time of day for cooking. However, it may be stored in the memory 3.

(Calorie table)
Note that the preference learning unit 12 determines not only information such as ingredients and names from the cooking history information, but also nutrients, calorie content, cooking type, cooking method, cooking time, and time required for cooking (cooking time). Can be extracted.

  The preference learning unit 12 can calculate the nutrient and calorie content of the historical dish using a nutrient table that defines the relationship between the content of each nutrient and the calorie content. This nutrient table is stored in advance in the memory 3 in the microwave oven 1.

  An example of the nutrient table will be described below with reference to FIG. FIG. 8 is a diagram showing the nutrient table 80. As shown in this figure, the nutrient table 80 defines the amount of calories contained for each food material such as beef streaks, beef tongue, and beef. In addition, the content of nutrients such as protein, carbohydrates, and carbohydrates is defined for each food.

  When calculating the intake calorie amount and the content nutrient content of the historical dish, the preference learning unit 12 first refers to the dish history information and specifies the type of ingredients and the amount of ingredients included in the historical dish. Next, with reference to the nutrient table 80 based on the specified information, the calorie content and the nutrient content for each food are calculated. Finally, the calorie content for all ingredients contained in the historical dish is summed up to calculate the calorie intake. Furthermore, the total amount of nutrients for each ingredient is totalized for all ingredients contained in the historical dish. Thereby, the amount of each nutrient contained in the historical dish is calculated.

  Note that the calculation method described above is merely an example. In addition, the preference learning unit 12 can use any method that can calculate the calorie content and nutrient content.

(Recommended food information for diet food)
As described above, the preference learning unit 12 specifies the user's past meal intake. For example, the calorie intake amount for each historical dish is obtained from the dish history information about the historical dish that the user has eaten in the past, and the average daily calorie intake is calculated.

  The recommended dish information determination unit 14 can determine, as recommended dish information, dish information suitable for the user to diet based on the calorie intake amount specified by the preference learning unit 12. For example, when the daily average calorie intake exceeds a reference value, the dish information having a calorie amount equal to or less than the average is determined as recommended dish information from the plurality of dish information. At this time, for example, with reference to calorie information included in advance in the dish information, dish information with a low calorie content is specified.

  Thereby, the microwave oven 1 can determine the dish information in consideration of the user's health as the recommended dish information.

(Deficient nutrients)
Moreover, the preference learning part 12 can specify the nutrient which a user lacks based on cooking history information. At this time, the dish information includes information about nutrients included in the dish information for each dish information. For example, vitamin C is 100 mg, dietary fiber is 10 g, and so on.

  At this time, the recommended dish information determination unit 14 determines the dish information including the deficient nutrients specified by the preference learning unit 12 as the recommended dish information. That is, when vitamin C is insufficient, the dish information about the dish rich in vitamin C is determined as the recommended dish information. Therefore, the microwave oven 1 can determine the dish information according to the nutritional status of the user as the recommended dish information.

(Recommendation of recommended dish information to users)
The control unit 2 determines at least one of the plurality of pieces of dish information as recommended dish information recommended to the user. Furthermore, the recommended recommended dish information is presented to the user to recommend the recommended recommended dish information to the user.

  The above processing will be described below with reference to FIG. FIG. 9 is a flowchart showing a flow of processing when the controller 2 determines recommended dish information and presents the determined recommended dish information to the user.

  First, the cooking environment information acquisition unit 16 acquires cooking environment information (step S90). At this time, as cooking environment information, for example, time information indicating the cooking time is acquired, or weather information indicating the current weather is acquired. In the example of FIG. 9, at least time information is acquired. The cooking environment information acquisition unit 16 outputs the acquired cooking environment information to the recommended dish information determination unit 14.

  Next, the recommended dish information determination unit 14 reads the preference information of the time represented by the time information from the memory 3 (step S91). Further, the dish information is read from the memory 3. (Step S92).

  The recommended dish information determination unit 14 calculates a recommendation degree for each dish information by using the input cooking environment information, the preference information and the dish information read from the memory 3 (step S93). Details of this processing will be described later.

After calculating the recommendation level for each dish information, the recommended dish information determination unit 14 determines recommended dish information recommended to the user (step S94). At this time, the recommended dish information determining unit 14 can determine at least one dish information among the plurality of dish information as the recommended dish information. For example, out of multiple dishes information
-Cooking information having the highest recommendation level-Multiple pieces of cooking information having a higher recommendation level than the reference value-A predetermined number of pieces of cooking information can be determined as recommended cooking information.

  The control unit 2 presents at least one recommended dish information determined by the recommended dish information determination unit 14 to the user. Specifically, the display processing unit 15 displays the dish name and image of the dish represented by the recommended dish information on the display 6 (step S95).

(Calculation of recommendation level)
A process when the recommended dish information determination unit 14 calculates a recommendation level for each dish information will be described below with reference to FIG. FIG. 10 is a flowchart showing the flow of processing when the recommended dish information determination unit 14 calculates the recommendation level for each dish information.

  As shown in this figure, the recommended dish information determination unit 14 first extracts dish feature information from the dish information (step S100). The cooking information usually includes a plurality of pieces of information different from each other, such as food material information representing food ingredients, cooking type information representing food types, and cooking method information representing cooking methods. Therefore, the plurality of pieces of dish characteristic information are read from the dish information one by one.

  Next, the recommended dish information determination unit 14 determines whether or not the read dish characteristic information is the ingredient information (step S101). When the result of the determination in step S101 is “true” (YES), the recommended dish information determination unit 14 accumulates the degree of preference for ingredients (step S102). That is, the value of the ingredient preference is specified from the preference information read in step S91 and added to the value stored in the memory 3.

  Next, the recommended dish information determination unit 14 accumulates the season of ingredients representing the degree of season of ingredients (step S103). At this time, based on the information that associates the food with the season of the food and the time information, the food with the time represented by the time information as the season is identified. For example, the table 110 shown in FIG. 11 is used. FIG. 11 is a diagram illustrating a table 110 that associates foodstuffs with the season of the foodstuff.

  As shown in this figure, the table 110 stores a value representing the degree of seasonality of each ingredient for each month. For example, for saury, August is stored as “1”, September through November as “2”, and December as “1”. Other months are “0”. The larger the value, the closer to the actual season. Therefore, the table 110 indicates that the season of saury is from August to December, and the degree of season increases from September to November.

  The recommended dish information determination unit 14 specifies the current time, that is, the month based on the time information. Then, a value representing the degree of season is read from the column corresponding to the ingredient indicated by the ingredient information in the table 110 and the specified month. The value read out in this way is added to the season of ingredients already stored in the memory 3, and the value is accumulated.

  On the other hand, when the result of the determination in step S101 is “false” (NO), the recommended dish information determination unit 14 determines whether the dish feature information is dish type information (step S104). When the result of the determination in step S104 is “true” (YES), the recommended dish information determination unit 14 accumulates the degree of preference for the dish type based on the dish history information (step S105). On the other hand, when the result of the determination in step S104 is “false” (NO), the recommended dish information determination unit 14 accumulates the degree of preference for the cooking method based on the dish history information (step S106).

  As described above, the recommended dish information determination unit 14 first identifies which dish feature the extracted dish feature information represents, and then accumulates the degree of preference for the identified dish feature. Next, it is determined whether the currently processed information is the last dish characteristic information included in the dish information (step S107).

  When the result of the determination in step S107 is “false” (NO), the processing shown in FIG. 10 returns to step S100. At this time, the recommended dish information determination unit 14 extracts new dish feature information from the dish information. In this manner, the recommended dish information determination unit 14 repeats the processes of steps S100 to S107 until a “true” result is obtained in the process of step S107.

On the other hand, when the result of the determination in step S107 is “true” (YES), the recommended dish information determination unit 14 calculates a recommendation degree for the dish information (step S108). Specifically,
Recommendation level = food preference × W _{1 +} foodstuff Shundo × W _{2 +} Cuisine species preference × W _{3 +} Recipes preference × W ₄ - using the formula of course penalty value, calculates a recommendation level. Here, in the above formulas, W ₁ is the weight of the food preference. W ₂ is the weight of the food season. W ₃ is the weight of the food species preference. W ₄ is the weight of the cooking method preference. The elapsed penalty value will be described later.

  After the recommended dish information determination unit 14 calculates the recommendation level, the process illustrated in FIG. 10 ends.

(Action / Effect)
As described above, the recommended dish information determination unit 14 determines at least one dish information corresponding to the cooking environment among the plurality of dish information as the recommended dish information. At this time, cooking environment information and a plurality of cooking information are used. In the cooking information, information representing various cooking environments, such as temperature and time suitable for a meal, is associated in advance with information for specifying a dish. Therefore, the recommended dish information determination unit 14 determines the dish information that satisfies the cooking environment information acquired by the cooking environment information acquisition unit 16 as recommended dish information.

  For example, it is assumed that the recommended dish information determination unit 14 determines that the current temperature is higher than the reference value based on the cooking environment information. At this time, in the dish information, recommended dish information that recommends to the user dish information that is defined as suitable when the temperature is higher than the reference value, for example, dish information about cold dishes such as cold noodles and salads. Determine as. Similarly, when the cooking time is specified based on the time information, the cooking information associated with the specified time in the cooking information is determined as the recommended cooking information. Therefore, the microwave oven 1 can more reliably determine the dish information that matches the user's request as the recommended dish information.

(Cooking using seasonal ingredients)
As described above, the recommended dish information determination unit 14 determines recommended dish information based on the recommendation level of the dish information. At this time, the dish information whose season of ingredients is higher than the standard can be preferentially determined as recommended dish information.

  Specifically, the recommended dish information determination unit 14 determines the time represented by the time information based on the information that associates the ingredients with the seasonal time of the ingredients and the time information acquired by the cooking environment information acquisition unit 16. Identify seasonal ingredients.

  The recommended dish information determination unit 14 determines the dish information about the dish that can be cooked using the identified ingredients as the recommended dish information. In other words, in the summer season, the dish information about the dish that can be cooked using vegetables and meat in the summer season is determined as the recommended dish information. On the other hand, in the winter season, dish information about a dish that can be cooked using fish and vegetables in winter is determined as recommended dish information. Therefore, the microwave oven 1 can determine the dish information about the dish that can be eaten deliciously in the season as recommended dish information.

(Elapsed penalty)
Note that the recommended dish information determination unit 14 can take measures not to recommend the same dish information as recommended dish information every time. Specifically, the recommendation degree of the dish information is used according to the elapsed date from the date when the cooking device 5 cooks the dish represented by the dish information in the past by using the penalty information for lowering the recommendation degree of the dish information. Can be lowered.

  FIG. 12 is a diagram illustrating a function 120 that represents the relationship between the number of days that have elapsed since the cooking device 5 cooked the dish represented by the dish information and the elapsed penalty value.

  The recommended dish information determination unit 14 can adjust the value of the recommendation degree using, for example, a progress penalty management table indicating the characteristics of the function 120. The function 120 has a characteristic that the elapsed penalty value decreases as the elapsed day value increases. Therefore, the recommended dish information determination unit 14 can easily calculate a higher recommendation level as the elapsed day value is larger.

Here, it is assumed that the number of days elapsed from the date when the cooking device 5 cooks a dish represented by certain dish information in the past is 10 days. Such elapsed days information is stored in the dish information every time the cooking device 5 cooks the dish represented by the recommended dish information, for example. Since the number of elapsed days is 10, the recommended dish information determination unit 14 acquires P (10) from the table 110 as the elapsed penalty value. Then, as described above, when the recommendation level of the dish information is obtained, the recommendation level = food preference level × W ₁ + seasonal food season × W ₂ + food type preference level × W ₃ + cooking method preference level × W ₄ -elapsed. Use the penalty value formula. That is, P (10) is subtracted in the equation. Therefore, the greater the elapsed penalty value, the lower the recommended recommendation value.

  As described above, the recommended dish information determination unit 14 determines the recommendation degree for the dish information when the dish represented by the dish information has been cooked by the cooking device 5 within a certain period in the past. Is calculated lower than the case where the cooking apparatus 5 has not cooked the food in the past certain period. In other words, when the cooking apparatus 5 has not cooked the dish represented by the dish information within the past certain period, the dish represented by the dish information is cooked within the past certain period. The recommended dish information is determined more preferentially than when the apparatus 5 has been cooked. Thereby, the microwave oven 1 can prevent determining the dish information about the dish that the cooking apparatus 5 has cooked in the past as the recommended dish information in a short period of time. Therefore, the user can always feel freshness in the recommended dish information.

(List of recommended dish information)
In the microwave oven 1, the display processing unit 15 may display recommended dish information recommended to the user as a list. This example will be described below with reference to FIG. FIG. 13 is a diagram showing a screen displaying a list of recommended dish information recommended to the user.

  As shown in this figure, the display processing unit 15 displays a plurality of recommended dish information determined by the recommended dish information determining unit 14 in a list. Specifically, six pieces of recommended dish information are displayed side by side in a matrix of 3 rows and 2 columns in one display screen. The user can select, for example, one of the dish names displayed as a list and obtain detailed information about the recommended dish information.

(Automatic cooking of recommended dish information)
Further, after confirming the screen of FIG. 13, the user selects recommended dish information about the dish that the cooking apparatus 5 wants to cook. In the microwave oven 1, the input processing unit 10 accepts selection of recommended dish information by the user. Thereby, the cooking processing unit 11 causes the cooking device 5 to cook the dish represented by the recommended dish information received by the input processing unit 10. Thereby, the cooking apparatus 5 cooks the dish represented by the selected recommended dish information using the material set by the user. Therefore, the microwave oven 1 can save time and effort for the user to cook the dish represented by the recommended dish information.

(Display of dish name and dish image)
In the screen of FIG. 13, the display processing unit 15 displays the dish name and image of the dish for each recommended dish information when presenting each recommended dish information to the user. Thereby, the microwave oven 1 can make a user understand at a glance what kind of dish the recommended dish information represents. Therefore, the user can easily select desired recommended dish information.

  In the present invention, the information displayed on the display 6 by the display processing unit 15 is not limited to the dish name and image of the dish represented by the recommended dish information. For example, it may be the time required for cooking the food, or the calorie intake. That is, the information displayed on the display 6 by the display processing unit 15 may be any information as long as it represents the details of the dish represented by the recommended dish information.

  The method for presenting the recommended dish information to the user is not limited to the list display described above as long as the user can appropriately know the recommended dish information, and any method may be used. For example, the sound of the dish name of the dish represented by the recommended dish information may be emitted through a speaker (not shown). In any case, the microwave oven 1 can appropriately present the determined recommended dish information to the user.

(Action / Effect)
As described above, the microwave oven 1 determines recommended dish information to be recommended to the user based on the user's past operation history, cooking environment and conditions, and presents the recommended dish information to the user. This saves the user the trouble of registering information about dishes that are usually cooked in the favorites list of the microwave oven 1. Furthermore, the microwave oven 1 can prevent recommending dish information about the dish cooked by the cooking apparatus 5 within a certain period in the past to the upper rank each time.

(Nutrition balance display)
The microwave oven 1 can present information about nutrients that the user has taken in the past. This example will be described below with reference to FIG. FIG. 14 is a diagram illustrating a screen in which a nutrition balance taken by a user in the past week is displayed as a graph.

  As shown in the figure, the display processing unit 15 displays on the display 6 a graph showing the nutritional balance taken by the user in the past week. The user who sees this can know the current nutritional balance. Therefore, it is possible to make an effort to effectively improve the future eating habits.

  Moreover, the microwave oven 1 can also recommend cooking information about cooking including nutrients that are lacking to the user to the user. In this case, the display processing unit 15 may display the recommended dish information on the dish including the deficient nutrients on the display 6.

  Moreover, the microwave oven 1 can also provide the user with dish information about dishes suitable for dieting based on the user's operation history. In this case, the display processing unit 15 may display diet food information on the display 6.

(Recommended dish information tab display)
In addition, the display processing unit 15 may display the determined plurality of recommended dish information on the display 6 by distinguishing them for each type of dish. Therefore, this example will be described below with reference to FIG. FIG. 15 is a diagram illustrating an example of a screen in which a plurality of recommended dish information is displayed separately for each type of dish.

  The recommended dish information determination unit 14 determines “recommended dish”, “recommended balanced dish”, and “recommended diet dish” as a plurality of recommended dish information. Thereby, as shown in FIG. 15, the display processing unit 15 displays “recommended food”, “recommended balanced food”, and “recommended diet food” on the display 6 in a tabular manner.

  By selecting each tab displayed on the display 6, the user can individually display different types of recommended dish information on the display 6.

(Cooking information processing system 160)
Note that the present invention can also be realized as a system including a plurality of devices. Therefore, the dish information processing system 160 according to the present embodiment will be described below with reference to FIG. FIG. 16 is a block diagram showing a main configuration of a dish information processing system 160 according to an embodiment of the present invention.

  As shown in this figure, the dish information processing system 160 is connected to a dish information processing apparatus 162, an automatic cooking apparatus 163, a TV apparatus 164, a refrigerator 165, and the Internet 167 connected to a home network 161. The weather information providing server 168 and the dish information providing server 169 are configured.

  The dish information processing apparatus 162 has various functions of the microwave oven 1 described above. In addition, the recommended dish information is determined in cooperation with the automatic cooking apparatus 163, the television apparatus 164, and the refrigerator 165. Further, the weather information providing server 168 and the dish information providing server 169 cooperate with each other through the Internet 167.

  In any case, the dish information processing apparatus 162 obtains necessary information from each cooperating apparatus, provides information to each apparatus, or instructs a predetermined process. Thereby, the usability for the user can be further improved.

(Cooperation with automatic cooking device 163)
The dish information processing apparatus 162 causes the automatic cooking apparatus 163 to cook the dish represented by the recommended dish information selected by the user. Thus, the automatic cooking device 163 cooks the dish represented by the designated recommended dish information in accordance with the cooking procedure defined in the recommended dish information. Therefore, the user can easily cook the recommended recommended dish information.

(Cooperation with TV device 164)
The television apparatus 164 receives broadcast waves such as data broadcasts, and acquires weather information such as weather, temperature, and humidity from the received broadcast waves. Thereby, the acquired weather information is provided to the cooking information processing apparatus 162 as cooking environment information.

  The television device 164 further stores a viewing history such as a cooking program viewed by the user and provides it to the cooking information processing device 162. Thereby, the dish information processing apparatus 162 can determine recommended dish information using program viewing history information representing a user's program viewing history in addition to cooking environment information and cooking information. Therefore, it is possible to determine recommended dish information that matches the user's preference and recommend it to the user.

(Cooperation with refrigerator 165)
The refrigerator 165 manages information about the currently stored ingredients. The refrigerator 165 stores foodstuffs, for example, using a technique described in JP-A-2002-81848. The dish information processing apparatus 162 acquires food material information representing stored food materials from the refrigerator 165 as cooking environment information. Thereby, the dish information processing apparatus 162 determines the dish information considering the ingredients stored in the refrigerator 165 as the recommended dish information. For example, cooking information about cooking that can be cooked using stored ingredients is preferentially determined as recommended cooking information.

(Cooperation with portable terminal device 166)
The dish information processing apparatus 162 outputs recommended dish information to the mobile terminal device 166 through communication or through a recording medium such as a memory card. In other words, an output unit (output means) (not shown) responsible for such output processing is provided. A user using the mobile terminal device 166 can use recommended dish information stored in the mobile terminal device 166 as a memo of the material, for example, when purchasing food.

(Cooperation with weather information providing server 168)
The weather information providing server 168 provides weather information representing weather conditions such as weather, temperature, and humidity to the dish information processing apparatus 162 via the Internet 167. Thereby, the dish information processing apparatus 162 acquires various weather information as cooking environment information. The dish information processing apparatus 162 considers the acquired weather information when determining recommended dish information. Specifically, dish information corresponding to the weather represented by the weather information is determined as recommended dish information. Thereby, the dish information about the dish more matched with the user's preference can be determined as the recommended dish information. For example, warm food information such as pots can be recommended to the user on a cold day.

(Cooperation with cooking information providing server 169)
The dish information providing server 169 provides the dish information to the dish information processing apparatus 162 through the Internet 167. That is, in the dish information processing apparatus 162, the dish information acquisition unit 17 acquires new dish information representing a new dish from the dish information providing server 169 via the communication device 7. Thereby, when determining the recommended dish information, the dish information processing apparatus 162 can also select the dish information represented by the acquired new dish information. In other words, the dish information processing apparatus 162 can recommend dish information about a dish suitable for the user from among more dish information. For example, the dish information represented by the obtained dish information and the dish information represented by the dish information based on the user operation history can be recommended to the user at the same time. Therefore, the range of dish information that can be determined as recommended dish information can be further expanded.

  In addition, the dish information processing system according to the present invention is not limited to the above-described configuration, and may be configured by a part of the various apparatuses constituting the dish information processing system 160.

  Further, in the dish information processing system 160, the dish information processing apparatus 162 includes information on a cooking history viewed by the user, information representing a search history such as a keyword when the user searches for dish information using a personal computer, and the like. Various types of information having a possibility of specifying the degree of preference of the user with respect to the dish information may be used when determining the recommended dish information as appropriate.

(Refrigerator 170)
The display 6 of the microwave oven 1 described above can be integrated with a refrigerator. Then, the refrigerator 170 provided with the display 6 is demonstrated below with reference to FIG. FIG. 17 is a diagram illustrating a refrigerator 170 including the display 6.

  As shown in this figure, the refrigerator 170 includes the display 6 of the microwave oven 1. Moreover, the control part 2 of the microwave oven 1 is also provided in the inside. Thereby, the refrigerator 170 has a recommendation function and a display function of recommended dish information realized by the control unit 2.

  Therefore, the refrigerator 170 can display the recommended dish information recommended to the user and the ingredient information about the ingredients stored in the refrigerator 170 on one display 6.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible in the range shown to the claim. In other words, embodiments obtained by combining technical means appropriately changed within the scope of the claims are also included in the technical scope of the present invention.

(Determine recommended dish information based on time information)
For example, the cooking environment information acquisition unit 16 acquires time information indicating time when cooking as cooking environment information. Specifically, time information representing at least one of a time zone, a day of the week, a month, and a season within a day when cooking is acquired.

  Based on the time information acquired by the cooking environment information acquisition unit 16, the recommended dish information determination unit 14 recommends a dish corresponding to the cooking time corresponding to the cooking time represented by the time information among the plurality of pieces of dish information. Determine as information. For example, when it is specified that the cooking time is morning, the dish information about light dishes suitable for breakfast is determined as recommended dish information. On the other hand, when it is specified that the cooking time is evening, the dish information about the popular dish suitable for dinner is determined as recommended dish information.

  Therefore, the microwave oven 1 can more reliably determine the dish information corresponding to the cooking time as the recommended dish information.

(Determine recommended dish information based on weather information)
For example, the cooking environment information acquisition part 16 acquires the weather information showing the weather at the time of cooking a dish as cooking environment information. For example, weather information representing at least one of weather, temperature, and humidity is acquired as weather information.

  The recommended dish information determination unit 14 recommends dish information corresponding to the weather as recommended dish information based on the weather information acquired by the cooking environment information acquisition unit 16. At this time, in the dish information, information on the weather suitable for eating is associated with information for specifying the dish in advance. For example, information representing “temperature 0 to 10 degrees” is associated with the dish information A, and information representing “temperature 25 to 30 degrees” is associated with the dish information B, respectively.

  Therefore, the recommended dish information determination unit 14 uses the association to specify the dish information corresponding to the weather represented by the weather information acquired by the cooking environment information acquisition unit 16 from the dish information. For example, when the temperature is high, cold dishes such as cold noodles and salad (cooking information B) are determined as recommended dish information, and when the temperature is cold, warm dishes such as grilled meat and hot pot (cooking information A) are determined as recommended dish information. . Therefore, the microwave oven 1 can more reliably determine dish information corresponding to the weather as recommended dish information.

(Acquisition of food information)
For example, the cooking environment information acquisition part 16 acquires the food material information showing the food which a user has as cooking environment information. For example, food material information representing a stored food material is acquired from a refrigerator having a function of managing information about the food material.

  The recommended dish information determination unit 14 determines, as recommended dish information, dish information about a dish that can be cooked using the ingredients of the user, based on the ingredient information acquired by the cooking environment information acquisition unit 16. For example, suppose that it specified based on foodstuff information that the fish was preserve | saved in the refrigerator. At this time, the dish information about the dish (for example, Meuniere) that can be cooked using fish is determined as the recommended dish information.

  As described above, the microwave oven 1 can more reliably determine dish information about dishes using ingredients familiar to the user as recommended dish information. Therefore, the dish information about the dish that the user can cook in a short time can be determined as the recommended dish information.

(Learning preference information for each hour)
In addition, the dish history information includes time information representing the time in a day when the history dish is cooked. For example, time information indicating “7:30 to 40 minutes” as a time zone when the first historical dish is cooked, and “8 to 8 pm as time when the second historical dish is cooked” Time information representing “30 minutes”.

  The preference learning unit 12 learns the user's preference information for each hour based on the time information included in the cooking history information. For example, the preference information from 7:00 am to 8:00 am and the preference information from 6:00 pm to 8:00 pm are individually learned.

  The recommended dish information determination unit 14 determines the dish information corresponding to the preference information for each hour as the recommended dish information for each hour based on the learned preference information. For example, the dish information corresponding to the preference information in the time from 7 am to 8 am is determined as recommended dish information for breakfast. On the other hand, the dish information corresponding to the preference information from 6:00 pm to 8:00 pm is determined as recommended dish information for dinner.

  As described above, the microwave oven 1 can reliably determine the dish information about the dish that matches the user's preference as the recommended dish information by time.

(Cooking that meets cooking conditions)
For example, the input processing unit 10 accepts input of cooking conditions by the user. For example, information input such as 18:00 in the evening as cooking time is accepted as input of cooking conditions. The recommended dish information determination unit 14 determines the dish information satisfying the cooking condition received by the cooking condition input unit as the recommended dish information.

  For a user, the time when the user wants to recommend a dish may be different from the time when the recommended dish is actually cooked. For example, at the time of cooking lunch, you may want to recommend in advance what you want to make for dinner. In such a case, even if the microwave oven 1 recommends a dish suitable for lunch at noon, it cannot be said that it has answered the request of a user who wants to recommend dinner at noon.

  Therefore, for example, when the user designates dinner as a cooking condition at noon, the recommended dish information determination unit 14 determines the dish information about the dish suitable for dinner as recommended dish information even if the present is noon. To do. Thereby, the microwave oven 1 can determine the recommended dish information according to a user's request.

  Moreover, it is preferable that the cooking condition received by the cooking condition input means is at least one of a time zone during a meal, a condition related to diet, a condition related to food allergy, and a condition related to nutritional balance. Thereby, the microwave oven 1 can determine cooking information satisfying each cooking condition such as diet and nutrition balance as recommended cooking information. In addition, cooking information that does not include these ingredients can be determined as recommended cooking information by using cooking ingredients that cannot be eaten due to food allergies as cooking conditions.

(Cooking information processing method)
