Of course, for example, a product database in which the product code is associated with the designated storage location is stored in advance in the storage unit 22 and the like, and the product code of the product selected by the storage location determination unit 212 in step S401 is used as a key from the product database. The designated storage location may be acquired.

  When it is determined that the item storage location 2213 does not match the designated storage location (N in step S403), the storage location determination unit 212 determines whether the designated storage location is “frozen” or “refrigerated” ( Step S404). When the designated storage location is “frozen”, the storage location 2213 is “refrigerated”, and when the designated storage location is “refrigerated”, the storage location 2213 is “frozen”.

  If it is determined that the designated storage location is “frozen” (“frozen” in step S404), the in-chamber information acquisition unit 211 shortens the expiration date 2214 of the item selected in step S401 (step S405). This is because the goods that should be frozen are refrigerated and the expiry date is considered to be accelerated. For example, the in-chamber information acquisition unit 211 may shorten the same predetermined number of days regardless of the type of the item, or may select and shorten the predetermined number of days depending on the type of the item.

  When it is determined that the designated storage location is “refrigerated” (“refrigerated” in step S404), the in-chamber information acquisition unit 211 extends the expiration date 2214 of the item selected in step S401 (step S406). This is because the goods that are originally recommended for refrigeration are frozen, and the expiry date is considered to be extended. For example, the in-chamber information acquisition unit 211 may extend the same predetermined number of days regardless of the type of the item, or may select and extend a predetermined number of days depending on the type of the item.

  When it is determined that the item storage location 2213 matches the designated storage location (Y in step S403), after the processing in step S405 or after the processing in step S406, the in-chamber information acquisition unit 211 receives the received warehouse. It is determined whether all items have been selected from the inside information (step S407).

  If it is determined that not all items have been selected (N in step S407), the in-chamber information acquisition unit 211 executes the process of step S401 again. If it is determined that all items have been selected (Y in step S407), the in-chamber information acquisition unit 211 ends the process illustrated in this flowchart.

  The shopping support apparatus 20 can generate a list of items stored in the refrigerator 10 based on information from the user's refrigerator 10 according to the flowchart shown in FIG. Further, the shopping support apparatus 20 can adjust the expiration date designated by the manufacturer or the like to a more accurate expiration date that is realistic based on the information indicating the actual storage location of the item.

  FIG. 10 is a flowchart illustrating an example of a shopping list generation process of the shopping support apparatus. FIG. 10 is a diagram illustrating an example of details of the process in step S5 of FIG.

  First, the shopping list generation unit 213 compares the in-store product list generated in step S4 with the shopping list history of the user for the user authenticated in step S1 (step S501). Specifically, the shopping list generation unit 213 extracts the shopping list history of the user from the shopping list history DB 223 using the customer code of the user authenticated in step S1 as a key. In addition, the shopping list generation unit 213 compares the in-store item list with the shopping list history, and the product that exists in the shopping list history and does not exist in the in-store item list (hereinafter simply referred to as “a product that does not exist in the store”). ”) Is specified.

  Then, the shopping list generation unit 213 determines whether or not a product that does not exist in the warehouse has been identified (step S502).

  When it determines with the goods which do not exist in a warehouse having been specified (Y in step S502), the shopping list production | generation part 213 performs the process of following step S503 and step S504 about each goods which do not exist in a warehouse.

  The shopping list generation unit 213 determines whether or not a product that does not exist in the warehouse is a special product (step S503). Specifically, the shopping list generation unit 213 refers to the shopping list history extracted in step S501 and determines whether or not the special product flag 2233 of the product that does not exist in the warehouse indicates that the product is a special product. To do.

  When it is determined that the product that does not exist in the warehouse is not a special product (N in step S503), the shopping list generation unit 213 determines the product as a candidate product, and records the product related to the user authenticated in step S1. Are added to the shopping list (step S504). Specifically, the shopping list generation unit 213 determines the user code of the user authenticated in step S1, the product code of the product not existing in the warehouse, the product name of the product, and the product as candidates. The reasons are associated with each other and stored in the shopping list DB 222. The product code and the product name may be acquired from the shopping list history. The reason 2223 may be set with information indicating that the product is out of stock from the refrigerator 10.

  When it is determined that a product that does not exist in the warehouse is not specified (N in step S502), or after the processing of step S503 or step S504 is completed for all the products that do not exist in the warehouse, the shopping list generation unit 213 Refers to the in-store goods list generated in step S4 for the user authenticated in step S1 (step S505). And the shopping list production | generation part 213 performs the process of following step S506-S509 about each item contained in the goods list in a warehouse.

  The shopping list generation unit 213 determines whether or not the current date exceeds the product expiration date 2214 (step S506).

  If it is determined that the current date has exceeded the product expiration date 2214 (Y in step S506), the shopping list generation unit 213 determines a product corresponding to the product as a candidate product, and records a record related to the product. Then, it is added to the shopping list of the user authenticated in step S1 (step S507). Specifically, the shopping list generation unit 213 determines the customer code of the user authenticated in step S1, the product code of the product corresponding to the product whose expiration date has been exceeded, the product name of the product, and the product as a candidate. Is stored in the shopping list DB 222 in association with the reason determined as. For the product code and product name of the product, the product code and product name of the product whose expiration date has been exceeded may be acquired from the in-store product list. The reason 2223 may be set with information indicating that the item has expired.

  When it is determined that the current date does not exceed the product expiration date 2214 (N in step S506), or after the processing in step S507, the shopping list creation unit 213 determines that the current date is the product expiration date 2214. Is determined (for example, whether it is equal to or less than a predetermined number of days until the expiration date) (step S508).

  If it is determined that the current date is close to the product expiration date 2214 (Y in step S508), the shopping list generation unit 213 determines a product corresponding to the product as a candidate product, and records a record related to the product in step S1. Is added to the shopping list of the user authenticated in step S509. Specifically, the shopping list generation unit 213 selects the customer code of the user authenticated in step S1, the product code of the product corresponding to the product close to the expiration date, the product name of the product, and the product as a candidate. The determined reason is stored in the shopping list DB 222 in association with the reason. As for the product code and product name of the product, the product code and product name of an item whose expiration date is close may be acquired from the in-store product list. The reason 2223 may be set with information indicating that the expiry date of the item is near.

  After the processing in step S506 or step S507 and the processing in step S508 or step S509 are completed for all the items included in the in-store item list, the shopping list generation unit 213 purchases the user authenticated in step S1. The history is referred to (step S510). For example, the purchase history may be stored in advance in the storage unit 22 or the like in association with a customer code, a purchase date, a product code of a purchased product, a product name of the product, and the like.

  Then, the shopping list generation unit 213 determines whether or not there is a product at the purchase time (step S511). The method for analyzing the purchase history and specifying the product at the purchase time is not particularly limited. For example, the shopping list generation unit 213 selects a product that is purchased regularly (for example, at intervals of 20 to 30 days). Then, it is determined whether or not the current date is included in the next purchase time (whether or not the purchase time has come). And the shopping list production | generation part 213 determines the goods which determined with the purchase time having come as a candidate goods, and performs the process of following step S512 about each of the said goods.

  The shopping list generation unit 213 adds a record relating to the product determined to have arrived at the purchase time to the shopping list of the user authenticated in step S1 (step S512). Specifically, the shopping list generation unit 213 determines the customer code of the user authenticated in step S1, the product code of the product for which the purchase time has arrived, the product name of the product, and the product as candidates. The reasons are associated with each other and stored in the shopping list DB 222. The product code and product name of the product may be acquired from the purchase history. Information indicating that it is the purchase time of the product may be set in the reason 2223.

  When it is determined that there is no product at the purchase time (N in step S511), or after the processing of step S512 is completed for all the products for which the purchase time has come, the shopping list generation unit 213 performs the processing shown in this flowchart. finish.

  According to the flowchart shown in FIG. 10 described above, the shopping support apparatus 20 can identify candidate products based on the difference between the in-store item list of the user's refrigerator 10 and the shopping list history. In addition, by comparing the item list with the shopping list history instead of the item list with the purchase history, the products that have been listed as candidates can be included in the shopping list regardless of whether or not they were actually purchased. be able to. When the purchase history is used, a product that is not actually purchased even though the user wants it may leave the shopping list. Moreover, the shopping assistance apparatus 20 can specify candidate goods based on the expiration date of the goods list in a warehouse. Moreover, the shopping assistance apparatus 20 can specify candidate goods based on a user's purchase history.

  FIG. 11 is a diagram illustrating an example of an interface screen for editing a shopping list. FIG. 11 is a diagram illustrating an example of the screen displayed in step S6 of FIG.

  The screen 500 includes a shopping list column 510 for displaying a shopping list, a selection column 520 for selecting a deletion target from candidate products included in the shopping list, a delete button 521 for instructing deletion of the selected candidate product, and addition to the shopping list An input field 530 for inputting the product name of the target candidate product, an add button 531 for instructing addition of the input candidate product, a confirmation button 540 for instructing confirmation of the contents of the shopping list, and the like are included. In the example of FIG. 11, the shopping list column 510 includes, for each candidate product, a column that displays the product name of the product and a column that displays the reason why the product is determined to be purchased. Yes.

  The shopping list generation unit 213 displays the product name 2222 and the reason 2223 of each candidate product in the shopping list column 510 based on the shopping list generated in step S5. In the example of FIG. 11, the reason “out of stock” is displayed for the product name “milk”. That is, “milk” is a candidate product added to the shopping list in step S504 of FIG. In addition, the reason “expired” is displayed for the product name “cabbage”. That is, “cabbage” is a candidate product added to the shopping list in step S507 of FIG.

Thereby, the shopping list displayed in the shopping list column 510 is also updated.

  When the shopping list generation unit 213 receives an operation on the confirmation button 540 from the user terminal 30, the shopping list generation unit 213 stores the shopping list being displayed in the shopping list DB 222.

  The first embodiment of the present invention has been described above. According to this embodiment, a shopping list can be easily created. For example, according to the present embodiment, the refrigerator reads information on items in the warehouse, and a shopping list is generated based on the read information. Thereby, it is possible to reduce the time and effort for the user to create a shopping list. Further, it is possible to save the user from having to grasp the inventory status of the refrigerator. Further, for example, according to the present embodiment, when the user gives an instruction from the user terminal, the in-store information of the refrigerator is acquired, and a shopping list is generated based on the in-store information. Thereby, the user can obtain a shopping list at a desired timing, and can obtain a shopping list based on the refrigerator internal information at that timing.

<Second embodiment>
In the first embodiment described above, when there is an instruction from the user, the generation of the in-ware item list and the generation of the shopping list are performed, but in the second embodiment, when the refrigerator is in a predetermined state, When a product list is generated and a user gives an instruction, a shopping list is generated. Hereinafter, a description will be given focusing on differences from the first embodiment.

  The refrigerator 10 includes a first sensor (not shown) that detects opening / closing of the door of the freezer compartment 10F and a second sensor (not shown) that detects opening / closing of the door of the refrigerator compartment 10R. The control unit 11 detects the open / close state of the freezer compartment 10F based on the output signal from the first sensor, and detects the open / close state of the refrigerator compartment 10R based on the output signal from the second sensor.

  For example, the control unit 11 detects the open state of the freezer compartment 10F and then detects the closed state (that is, detects that the door of the freezer compartment 10F is closed) or the refrigerator compartment 10R. When the closed state is detected after the open state is detected (that is, when it is detected that the door of the refrigerator compartment 10R is closed), the first reading unit 12 is controlled, and the inside of the freezer compartment 10F is controlled. While reading the information such as the product code of the product, the second reading unit 13 is controlled to read the information such as the product code of the product in the refrigerator compartment 10R.

Based on the shopping list history and the like stored in the list history DB 223, candidate products for the user are determined, a shopping list including the candidate products is generated, and transmitted to the user terminal 30 of the user.

  FIG. 12 is a sequence diagram illustrating an example of a processing flow of the shopping support system according to the second embodiment of the present invention.

  (Step S11): The control unit 11 of the refrigerator 10 monitors whether or not the door of the freezer compartment 10F is closed and monitors whether or not the door of the refrigerator compartment 10R is closed. When it is detected that the door of the freezer compartment 10F is closed, or when the controller 11 detects that the door of the refrigerator compartment 10R is closed, the control unit 11 controls the first reading unit 12 to control the freezer compartment 10F. While reading the information such as the product code of the item inside, the second reading unit 13 is controlled to read the information such as the product code of the item in the refrigerator compartment 10R.

  (Step S12): Based on the information read in Step S11, the control unit 11 of the refrigerator 10 generates in-chamber information including information such as a product code and a storage location (freezer room or refrigerated room) for each item. Then, the data is transmitted to the shopping support apparatus 20 by the communication unit 14.

  (Step S <b> 13): When the in-store information acquisition unit 211 of the shopping support apparatus 20 receives the in-store information from the refrigerator 10 through the communication unit 23, the in-store information list is generated based on the in-store information. Since the detailed process of step S13 is the same as that of FIG. 9, description is abbreviate | omitted. The in-chamber information acquisition unit 211 specifies the user code of the user based on, for example, the refrigerator code of the refrigerator 10 that transmitted the in-chamber information and the customer information DB 220, and generates an in-store item list for the user. do it.

  (Step S14): Since this is the same as Step S1 in FIG.

  (Step S15): The shopping list generation unit 213 of the shopping support apparatus 20 is a candidate product for the user of the user terminal 30 based on the in-store item list, the shopping list history, etc. generated in Steps S11 to S13. And a shopping list including the candidate product is generated. The detailed process in step S15 is the same as that in FIG.

  (Step S16 to Step S20): Since this is the same as Step S6 to Step S10 in FIG.

  In FIG. 12, the processes in steps S14 to S20 are performed immediately after step S13, but are not limited thereto. That is, the process of step S11 to step S13 and the process of step S14 to step S20 can be executed at independent timings.

  The second embodiment of the present invention has been described above. According to the present embodiment, when the refrigerator 10 is opened and closed, the in-store goods list is updated to the latest state, and in the case of a shopping list generation request, the latest in-store article list is not updated. A shopping list is generated based on the in-store goods list. Therefore, compared with the first embodiment, the user can obtain a shopping list in a shorter time.

  Further, in the present embodiment, by defining the timing when the refrigerator 10 is opened and closed as the update timing of the in-store item list, for example, compared with the case of periodically updating the in-store item list, taking in / out the items to / from the refrigerator 10 Further, it is possible to immediately detect changes such as movement of goods between the freezer compartment 10F and the refrigerator compartment 10R and obtain more accurate in-house information.

<Modification>
The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist of the present invention.

  In the above-described embodiment, the special product is not included in the shopping list (step S503 in FIG. 10), but may be included in the shopping list when a predetermined condition is met. For example, when it is determined that a product that does not exist in the warehouse is a special product (Y in step S503), the shopping list generation unit 213 sets the current date of the special product at a time when the special product should be purchased. It is determined whether or not they are close (for example, a predetermined date when the special product is started to be used is stored in the storage unit in advance, and it is determined whether or not the predetermined date is equal to or less than a predetermined number of days). Then, when it is determined that the current date is close to the time when the special product should be purchased, the shopping list generation unit 213 determines a product corresponding to the special product as a candidate product and adds it to the shopping list. If it does in this way, a special product can be shown to a user as a candidate product according to time.

  In the above-described embodiment, the designated storage location includes freezing and refrigeration, but may include room temperature (normal temperature). In this case, in step S404 of FIG. 9, the storage location determination unit 212 determines whether the designated storage location is “freezing”, “refrigerated”, or “room temperature”. When it is determined that the designated storage location is “room temperature”, the in-chamber information acquisition unit 211 extends the expiration date 2214 of the item. This is because the products that are originally recommended to be stored at room temperature are refrigerated or frozen, and the expiration date is considered to be extended. When the designated storage location is determined to be “room temperature”, the storage location determination unit 212 determines whether the storage location 2213 of the item is “frozen” or “refrigerated”. The expiration date may be set longer than the case. In this way, the expiration date designated by the manufacturer or the like can be adjusted to a more accurate expiration date that is realistic.

  In the above embodiment, the expiration date is used. However, for example, a expiration date such as a best before date may be used instead of the expiration date.

  In the above-described embodiment, the freezing room 10F and the refrigerating room 10R are exemplified as the storage room, but are not limited thereto. As a storage room, various things can be considered, such as a vegetable room for storing vegetables and the like, and a freezing room for rapid freezing. In other words, the present invention can also be applied to a case where the refrigerator includes one or more storage rooms and includes a reading unit that reads information on items in each storage room.

  In the above-described embodiment, the shopping list generation request is transmitted from the user terminal 30, but is not limited thereto. For example, the control unit 11 of the refrigerator 10 may receive an instruction for generating a shopping list from the user through the operation unit 16 and transmit a shopping list generation request to the shopping support device 20 through the communication unit 14. In this way, the user can create a shopping list from the refrigerator 10.

  In the above-described embodiment, the shopping list is transmitted to the user terminal 30, but is not limited thereto. For example, the shopping list generation unit 213 transmits (outputs) a screen including the generated shopping list to the user's refrigerator 10 through the communication unit 23. When the control unit 11 of the refrigerator 10 receives a screen including a shopping list from the shopping support device 20 through the communication unit 14, the control unit 11 displays the screen on the display unit 15. In addition, the control unit 11 receives an instruction to edit and confirm the shopping list from the user through the operation unit 16 on the displayed screen, and sends an editing content and a shopping list confirmation request to the shopping support device 20 through the communication unit 14. Send to. In this way, the user can edit or confirm the shopping list from the refrigerator 10.

  In the second embodiment, when the refrigerator 10 detects that one of the doors of the freezer compartment 10F and the refrigerator compartment 10R is closed, the product code of the items in the refrigerator compartment 10F and the refrigerator compartment 10R, etc. Reading information, but not limited to this. For example, when the control unit 11 detects that the door of the freezer compartment 10F is closed, the control unit 11 reads information such as a product code of an item in the freezer compartment 10F, generates in-house information regarding the freezer compartment 10F, It transmits to the support apparatus 20. Moreover, when the control part 11 detects that the door of the refrigerator compartment 10R was closed, it reads the information, such as the product code of the goods in the refrigerator compartment 10R, produces | generates the in-chamber information regarding the refrigerator compartment 10R, and shopping It transmits to the support apparatus 20. When the in-chamber information acquisition unit 211 of the shopping support apparatus 20 receives the in-chamber information regarding the freezer room 10F, the record in the storage item 2213 of the user's in-house goods list is deleted and received. A new record may be added based on the internal information. In addition, when the in-chamber information acquisition unit 211 of the shopping support apparatus 20 receives the in-chamber information regarding the refrigerated room 10R, it deletes the record in which the storage location 2213 is “refrigerated room” from the user's in-store goods list, A new record may be added based on the received internal information. If it does in this way, the data amount which the refrigerator 10 and the shopping assistance apparatus 20 process will be reduced.

  In the above embodiment, the control unit 21 of the shopping support apparatus 20 outputs the generated in-store item list to the user terminal 30, and the control unit 31 of the user terminal 30 displays the received in-store item list on the display unit 33. May be displayed. In addition, the control unit 21 of the shopping support apparatus 20 outputs the generated in-store item list to the refrigerator 10, and the control unit 11 of the refrigerator 10 displays the received in-store item list on the display unit 15. Also good. In this way, the user can recognize the stock status in the refrigerator 10 without actually looking inside the refrigerator 10.

  In the first embodiment described above, the shopping support device 20 generates and stores the in-store item list, the shopping list, and the shopping list history. However, the refrigerator 10 may have such a function. . For example, the shopping support system includes a refrigerator 10 and a user terminal 30. The control unit 31 of the user terminal 30 transmits a shopping list generation request to the refrigerator 10. When the control unit 11 of the refrigerator 10 receives the shopping list generation request, the control unit 11 reads information such as product codes of the items in the freezer compartment 10F and the refrigerator compartment 10R, generates in-compartment information, and based on the in-compartment information. An in-compartment item list is generated and stored in the storage unit provided in the refrigerator 10. In addition, the control unit 11 generates a shopping list based on the generated in-store item list, shopping list history, and the like, and transmits (outputs) it to the user terminal 30. When receiving the screen including the shopping list from the refrigerator 10, the control unit 31 of the user terminal 30 displays the screen on the display unit 33. In addition, the control unit 31 receives an instruction to edit and confirm the shopping list from the user via the operation unit 34 on the displayed screen, and transmits the editing content and the shopping list confirmation request to the refrigerator 10. The control unit 11 of the refrigerator 10 edits and saves the shopping list based on the editing content and the shopping list confirmation request transmitted from the user terminal 30. In this way, the shopping list can be easily created without providing the shopping support device 20. Similarly, in the second embodiment described above, the shopping support device 20 generates and stores the in-store item list, the shopping list, and the shopping list history. However, the refrigerator 10 has such a function. May be.
