  Regarding food ingredients, “nutrition” and “cost” are the most important factors for general consumers, especially housewives. The conventional refrigerator with an inventory management function contributes to curbing food costs such as consumption of purchased products within the deadline and prevention of double purchase.

  Moreover, the conventional food material management method contributes to the selection of food materials that take nutritional aspects into consideration.

  However, the most important thing for general consumers is to make "nutrition" and "cost" optimally compatible. On the other hand, in the conventional example or a simple combination thereof, the heterogeneous data of the food storage period, the food price and the nutrient contained in the food are only presented separately, the data of nutrition and cost are integrated, There is a problem that the overall cost performance of ingredients has not been evaluated and presented.

  In addition, in order for consumers to use foods that balance nutrition and cost in an optimal manner, the overall cost performance of the above-mentioned foods can be divided into two categories: consumption of stock foods and future food purchases. It is necessary to present priority consumption ingredients for domestic stock and to present recommended purchase ingredients for the next and subsequent shopping, but there is no refrigerator in which both are implemented.

  As a result, in the above-mentioned conventional example, the consumer has to identify the ingredients that should be preferentially consumed by the consumer after reviewing the different types of data such as nutrients and prices. There is a problem that the selective consumption is rarely made.

  In addition, in the above-mentioned conventional example, there is a problem that it is difficult for consumers to determine the nutrients that are generally lacking in the scene of purchasing ingredients and to consider the balance of nutrition to be consumed in the future. There is also a problem that it is very difficult to select and purchase the most useful food for each person, taking into account a plurality of different types of factors in a comprehensive manner.

The present invention simultaneously achieves the presentation of priority consumption foods by comprehensive cost performance evaluation of stock foods and the purchase recommended foods that provide the best cost performance, which is a balance between price and consumer deficiency of nutrients. Accordingly, an object of the present invention is to provide a refrigerator that optimizes the process from the purchase to the consumption of consumer foods.

  The present invention relates to a refrigerator having an inventory management function, obtains user's food purchase information from a cash register via a storage medium or a communication network, and based on the food consumption information input by the user, the food inventory information is obtained. Generate and determine recommended nutrients for users by querying the nutrient database, determine candidate foods, determine recommended nutrients for users by querying the nutrient database, and determine candidate foods And it is a refrigerator which presents a purchase recommendation foodstuff to a user based on the nutrition sufficiency rate and the sales price acquired from the sales price database.

Further, the present invention receives food purchase information from a cash register via a storage medium, calculates and stores food stock information based on the food purchase information and the food consumption information input by the purchaser, Nutrients related to the above-mentioned ingredient inventory information are inquired to the nutrient database, and the sales price included in the above-mentioned ingredient purchase information and the quantity of nutrients that can be satisfied with the quantity of nutrients inquired to the nutrient database and to be supplied to consumers. This is a refrigerator that presents priority consumption foods that are desirable foods for consumers according to the nutritional fulfillment rate, which is the quantity, and the expiration date information.

According to the present invention, presentation of priority consumption foods by comprehensive cost performance evaluation of stock foods and presentation of recommended purchase foods that optimize cost performance, which is a balance between price and consumer's deficient nutrient supply, are performed simultaneously. By realizing it, there is an effect that it is possible to optimize the process from the purchase of the food of the consumer to the consumption.

  The best mode for carrying out the invention is the following examples.

  FIG. 1 is an overall configuration diagram illustrating a refrigerator 100 that is Embodiment 1 of the present invention.

  The refrigerator 100 is connected to the cash register CR1 provided in the foodstuff store ST1 via the portable terminal T1. The refrigerator 100 is connected to the food nutrient information database DB1 via the communication network NW1, and is connected to the product price information database DB2 provided in the food dealer ST1 via the communication network NW2.

  Note that a dedicated card, an information receiving terminal, and an information receiving medium may be used instead of the portable terminal T1.

  The refrigerator 100 includes an ingredient purchase information receiving means 10, an ingredient consumption information input means 20, an inventory information creating means 30, a time recording means 31, a first database inquiry means 41, and a second database inquiry means 42. , Information adding means 43, refrigerator inventory recommended consumption food evaluation means 50, deficient nutrient determination means 60, store inventory food cost performance evaluation / determination means 70, and display means 80.

  The food purchase information receiving means 10 receives a plurality of information such as prices related to purchased products from the cash register CR1 via an information communication terminal such as a mobile phone or a card-type memory.

  The inventory information creation means 30 includes consumption information input by the food purchaser via the consumption information input means 20, food purchase information input via the information reception means 10, and a time record output by the time recording means 31. Inventory information is created based on inventory period information corresponding to the information.

  The first database inquiry means 41 inquires the ingredient nutrient database DB1 existing on the external network NW1 about the nutrient information on the stock ingredients.

  The information adding means 43 is means for adding the contained nutrient information inquired to the food nutrient information database DB1 by the nutrient database inquiry means 42 to the food stock information.

  The refrigerator stock recommended consumption food evaluation means 50 evaluates the cost performance of the stock food based on the integrated information.

  The deficient nutrient determination means 60 determines deficient nutrients based on the nutrient balance of the stock food.

  Based on the deficient nutrient information determined by the deficient nutrient determination means 60, the second database inquiry means 42 re-inquires the food nutrient database DB1 existing on the external network NW1 for potential candidate food supplementing the deficient nutrient.

  The database inquiry means inquires about the potential candidate foods to the commodity price database DB2 provided in the food retail store ST1 near the consumer residence existing on the external network NW2.

  The retailer inventory food cost performance notation / determination means 70 comprehensively determines retail sales foodstuffs that have the best cost performance for consumers from the price and nutrient data.

  The display means 80 displays the priority consumption food list and the purchase recommended food list based on the cost performance evaluation of the stock ingredients and the cost performance evaluation of the retail store sales ingredients. The “priority consumption food list” is a list shown on the display of FIG. 5, and the “purchased recommended food list” is a list shown on the display of FIG.

  Next, the operation of the refrigerator 10 will be described.

  FIG. 2 is a flowchart showing the operation of the refrigerator 100.

  When a consumer purchases a predetermined ingredient (S1), at the time of accounting, the consumer purchase information useful for inventory management such as product name, purchase date, expiry date, price, weight, quantity, etc. is obtained from the cash register CR1. To the mobile terminal T1 and receive the food purchase information (S2) or record it in the card-type memory.

  After returning home, the consumer transmits the food purchase information from the portable terminal T1 to the information receiving means 10 of the refrigerator 100, or the food purchase information from the card type memory in which the food purchase information is written. Receiving means 10 reads, refrigerator 100 creates and stores a food stock information list based on the received food purchase information.

  Moreover, the date and time memorize | stored as an inventory foodstuff list | wrist is recorded, and the time recording means 31 updates time progress information regularly after that. When the consumer consumes the food to some extent (S3), the food consumption information input means 20 inputs information on the consumed food. When consumed completely, the food consumption information input means 20 deletes the food from the food stock information list in the same manner as described above. In this way, the food stock information is updated (S4).

  For each newly purchased ingredient included in the ingredient inventory information list updated by the above operation, the nutrient database inquiry means 42 inquires about the contained nutrient information to the ingredient nutrient information database DB1 existing on the external network NW1 (S5). . Thereafter, the inquiry result (content nutrient information) is received (S6), and the information addition means 43 adds the inquired content nutrient information to the food stock information.

  Based on the additional food stock information list, the deficient nutrient determination means 60 estimates the nutrition intake balance of the consumer and determines at least one deficient nutrient (S7).

  The deficient nutrient determination means 60 is an appropriate nutrition based on, for example, the 6th revised Japanese nutrition requirement (http://www1.mhlw.go.jp/shingi/s9906/s0628-1_11.html) announced by the Ministry of Health, Labor and Welfare. Calculate the intake balance and identify nutrients that greatly disturb the balance. Instead of using the 6th revised Japanese nutrition requirements announced by the Ministry of Health, Labor and Welfare, other data may be used as long as the data shows the standard or ideal nutritional balance of Japanese. .

  Here, it is determined whether the food is purchased or consumed (S7a). If the food is purchased, the process proceeds to S8. If the food is consumed, the process proceeds to S11.

  From this deficient nutrient information, the food nutrient information database DB1 is again queried (S8), and a candidate list of food supplements (deficient nutrient supplemented food information) is created.

  For each candidate ingredient included in this ingredient candidate list, the product price database DB2 of the neighboring ingredient store ST1 is inquired, and the cost performance of the candidate ingredient (to nutritional sufficiency rate) is calculated (S9). Based on this, the recommended purchase ingredients are presented on the display means 80. The cost performance CP of the candidate food is calculated based on, for example, the following formula (1).

CP = K ₁ ^* Nu ^* (Bu / (Pr ^* K ₂ ) …… Equation (1)
In the above formula (1), Nu = nutrient sufficiency rate, Pr = food price at a specific food store ST1, Bu = food purchase budget in household, K ₁ , K ₂ = adjustment parameters. The ingredients are ranked according to the value of the cost performance CP of the candidate ingredients and presented on the display means 80. The nutrient sufficiency rate Nu is the amount of nutrients that can be satisfied relative to the amount of nutrients to be supplied to the consumer.

  If the value of the cost performance CP of the candidate food is large, it indicates that the food is a low-cost high-performance food, and is a purchase recommended food that is recommended for purchase. The purchase recommended food is output to the display device 80 (S10).

  The calculation formula of the cost performance CP of the candidate food may not be the same as the above formula (1), and the nutritional sufficiency rate contributes to increasing the cost performance CP of the candidate food, and the high price of the food is the candidate food If it is an expression that contributes to reducing the cost performance CP of the household, and that the budget for purchasing ingredients in the household contributes to reducing the impact of the price of ingredients on the cost performance CP, formulas other than the above formula (1) It may be used.

  As a result, a candidate product with a large cost performance CP is presented as a recommended purchase ingredient on the display means 80, and if the consumer views the display means 80, the consumer purchases an ingredient that is inexpensive and beneficial in terms of nutrition. Is encouraged and costs can be minimized.

On the other hand, for the foodstuffs in stock, the nutritional sufficiency ratio Nu of each stock foodstuff is calculated from the stock history so far, and the purchase price Pr, the household food budget Bu, the stock period Pe, the expiration date Fd, the purchase date D, the adjustment From the parameters K ₃ , K ₄ , K ₅ , for example, an early consumption recommendation index RIEC is calculated based on the following equation (2) (S 11). The early consumption recommendation index RIEC is an index indicating that the larger the value, the higher the cost and the higher the performance of the food, and the food that should be consumed preferentially.

RIEC = K ₃ * Nu * (Pr / (Bu * K ₄ )) * (Pe / ((Fd−D) * K ₅ )) …… Equation (2)
And a consumption recommendation foodstuff is output (S12). Note that a food with a large early consumption recommendation index RIEC is a priority consumption recommended food.

  The higher the nutritional sufficiency rate, the larger the recommended early consumption index RIEC, the higher the food price, the larger the recommended early consumption index RIEC, and the larger the food purchase budget in the household, the faster the recommended consumption index RIEC for food prices. The above formula (2) is a formula in which the early consumption recommendation index RIEC becomes smaller as the remaining shelf life calculated from the purchase date and the expiration date becomes smaller, and the early consumption recommendation index RIEC becomes smaller as the inventory period becomes shorter. ) (Calculation formula of recommended early consumption index RIEC) may be used instead.

  By doing as described above, the food with a large early consumption recommendation index RIEC is presented as the priority consumption food on the display means 80, and the consumer is high in price, beneficial in terms of nutrition, and has a long inventory period. The food is encouraged to be consumed quickly, and the economic loss can be minimized while enjoying the maximum nutritional benefits.

  These priority consumption ingredients and recommended purchase ingredients are displayed on the display means 80 every time the inventory information is updated, and the consumer can select the most suitable ingredients in stock and new purchases in terms of both cost and nutrition. Can be achieved.

  Next, in the first embodiment, a procedure for using the refrigerator 100 will be described.

  FIG. 3 is a diagram showing an overview of the refrigerator 100.

  On the surface of the refrigerator 100, information receiving means 10, food consumption information input means 20, and display means 80 are provided.

  When the consumer finishes shopping and pays, the information receiving means 10 receives the food purchase information by connecting or inserting the portable terminal T1 or the super-issued special card, etc. that he / she brought into the information receiving means 10 To do. That is, after returning home, the consumer uses the information receiving means 10 and transmits the food purchase information to the refrigerator 100. Thereby, the inventory information in the refrigerator 100 is updated.

  FIG. 4 is a diagram illustrating an example of the current total inventory information in the refrigerator 100.

  As shown in FIG. 4, when the “all inventory list” button is pressed after the display unit 80 is turned on, the current total inventory information in the refrigerator 100 is displayed on the display unit 80.

  That is, the refrigerator 200 uses the mobile terminal T1 or a dedicated card in the refrigerator 100 to receive the ingredient purchase information via the external communication network NW3, instead of receiving the ingredient purchase information. It is a refrigerator that receives directly.

According to the refrigerator 200, it is possible to further reduce the amount of work for consumers than the refrigerator 100, and achieve optimal stock consumption and new purchase of food from both the cost and nutrition aspects.

  In Embodiment 3 of the present invention, storage means for long-term purchase history information is added to the refrigerators 100 and 200, and recommended purchase ingredients are displayed on the display means 80 based on the purchase history information stored in the storage means. This is an embodiment in which the number of purchase histories is displayed simultaneously when presenting.

  Instead of displaying the number of purchase histories, the recommended purchase ingredients with a large purchase history and the recommended purchase ingredients with a small purchase history may be ranked and displayed. In other words, the items may be displayed in order of purchase history or in ascending order.

  In general, since consumers tend to look at foods that they are accustomed to buying, there is a strong tendency to purchase foods that they are accustomed to buying again, and the variety of ingested ingredients is fixed.

However, according to Example 3, the consumer is a low-cost and high-performance food, and provided with an opportunity to know information on the food that has not been noticed so far, has not been noticed until now Diversity of eating habits is increased by selecting and purchasing fresh ingredients.

  In the fourth embodiment of the present invention, a means for transmitting recommended purchase food information from the refrigerator 100 is added to the configurations of the first, second, and third embodiments, and the purchase recommended food information is received by the mobile terminal T1, and purchase recommendation It is an Example which shows foodstuff information in portable terminal T1.

  According to the fourth embodiment, the recommended purchase food information can be confirmed even outside the home, and the low-cost and high-performance food can be more easily purchased for the consumer.

  Purchase recommended food information may be stored in a small memory such as an IC card or an SD card. In this case, the consumer may be able to confirm purchase recommended food information by connecting the small memory to a small memory compatible device installed in a store and viewing the display.

  That is, in the above-described embodiment, the nutrient database DB1 on the external network and the product price database DB2 of the food retailer ST1 on the basis of the input or transmission of the food purchase information and the food inventory information that has been updated with the consumption of the food The priority consumption foods by the inventory food material cost performance evaluation of the home refrigerator and the purchase recommended foods by the dealer stock food cost performance evaluation are presented.

  As a result, the food consumer can know the priority consumption stock food and the recommended purchase food by performing only simple operations of transmitting the food purchase information when purchasing the food and inputting the consumption information when using the food. It is possible for the consumer to manage the food inventory that is most beneficial overall.

  According to the above-mentioned example, presentation of priority consumption foods by comprehensive cost performance evaluation of stock ingredients and presentation of recommended purchase ingredients that optimize cost performance which is a balance between price and consumer's deficient nutrient supply, By realizing at the same time, it is possible to provide a refrigerator capable of optimizing the process from the purchase of food to consumption by the consumer.

This can encourage consumption within the shelf life so as not to waste high-cost, high-performance ingredients, that is, expensive and consumer-rich nutrients, for home refrigerator inventory, Further, in future purchasing activities, it is possible to promote the purchase of low-cost and high-performance foods, that is, foods that have a greater effect of correcting the nutritional balance of consumers at a low price.
