FIG. 3 is a flow chart illustrating an operation of providing refrigerator 100 and mobile terminal 200 of FIG. 2 with purchase recommendation information for a currently recognized product to a user, and updating purchase information of a corresponding product Fig. In the following description, it is assumed that a database corresponding to an article to be purchased by the user is already formed in the refrigerator 100 for convenience of explanation, and the user scans the identification code of the article to be purchased through his or her mobile terminal 200 Will be described below.

3, when the function of scanning an identification code by a user is activated, the mobile terminal 200 detects an identification code from an image sensed from a scanning unit (not shown) of the mobile terminal 200 . When the identification code is detected, the product information can be recognized from the identification code (S300). When the product information is recognized from the identification code, the recognized product information can be displayed on the display unit 210 of the mobile terminal 200. [

Meanwhile, when the product information is recognized, the mobile terminal 200 can transmit the recognized product information to the refrigerator 100 (S302). The refrigerator 100 may then receive the product information recognized from the identification code. Then, a database of articles corresponding to the received product information can be selected (S304).

On the other hand, if the goods database corresponding to the received product information is selected in step S304, the controller 110 determines whether the remaining consumption period of the currently received product information and / or the price information of the goods corresponding to the received product information (S306). Here, the 'consumption period' may mean a period in which the user normally consumes the article corresponding to the currently received product information. The term " remaining consumption period " means a period obtained by subtracting the period from the most recent purchase of the article corresponding to the product information currently received from the consumption period to the present, Which is the remaining period during the consumption period.

The consumption period may be calculated based on the purchase pattern of the user analyzed from the database of the goods corresponding to the received product information. That is, if the article corresponding to the received product information is 'milk' and the user purchases three milk on average every 6 days, the consumption period per unit of 'milk' according to the purchase pattern of the user is 3 It can be a job.

In step S308, the control unit 110 may determine whether to recommend the purchase of the article based on the presence / absence of the remaining consumption period and the price information included in the product information received in step S302.

For example, the controller 110 can determine that the article is not needed if the current remaining consumption period remains. You may not recommend purchasing the item. However, if the price of the article is low at a certain level or less, it may be recommended to purchase the article.

On the other hand, the controller 110 can determine that the article is necessary if the current remaining consumption period remains. You can then recommend purchasing the item. However, if the price of the article is above a certain level, it may not recommend purchasing the article. The operation of the refrigerator 100 that determines whether or not the current mobile terminal 200 recommends the purchase of the article corresponding to the recognized product information based on the presence or absence of the remaining consumption period calculated in step S306 and the price information of the article The process will be described in more detail with reference to FIG.

Meanwhile, if the purchase recommendation of the product is determined, the control unit 110 may transmit the purchase recommendation result to the mobile terminal 200 in response to the product information transmitted in step S302 (S310). Then, the mobile terminal 200 can display the received purchase recommendation result through the display unit 210 of the mobile terminal 200 (S312).

On the other hand, in step S302, the mobile terminal 200 can transmit the information of the current location together with the recognized product information. In this case, the refrigerator 100 may further transmit the result of collecting the information of the other selling place selling the article corresponding to the recognized product information around the position of the other mobile terminal 200, together with the purchase recommendation result . Then, the mobile terminal 200 can display the information of the other sales agents transmitted through the display unit 210 of the mobile terminal 200.

Meanwhile, the information of the other selling place may further include information of other selling places searched not only around the position of the mobile terminal 200 but also around the at least one specified position. It should be noted that the information of the other selling place may include information of the online selling place as well as the offline selling place. The operation of the refrigerator 100, which collects the information of other sellers and transmits the collected information together with the purchase recommendation result, will be described in more detail with reference to FIG.

Meanwhile, if the purchase recommendation result is displayed in step S312, the mobile terminal 200 can detect whether the article in which the current product information is recognized is purchased by the user (S314). For example, the control unit of the mobile terminal 200 may be connected to the mobile terminal 200 or another payment means (for example, a credit card for which payment information is set to be transmitted to the mobile terminal 200) It is possible to detect whether or not the purchase information of the article in which the product information is recognized is contained in the payment history. If the purchase information of the article in which the product information is recognized is included, it can be determined that the article is purchased.

The control unit of the mobile terminal 200 may detect whether the product information selected by the user is present among the product information displayed on the display unit 210 of the mobile terminal 200 in step S314. If there is product information selected by the user, it can be determined that the user has purchased the article corresponding to the product information.

On the other hand, if the purchase of the article corresponding to the recognized product information is not detected until the preset time elapses while the product information is recognized, the control unit of the mobile terminal 200 responds to the recognized product information It can be judged that the article is not purchased. Or the control unit of the mobile terminal 200 detects the position of the mobile terminal 200 in a state in which the product information is recognized and as a result the mobile terminal 200 moves to the outside of the shop where the article corresponding to the product information is sold , It may be determined that the user has left the retailer without purchasing the article. In this case, the mobile terminal 200 may determine that the user has not purchased the article corresponding to the recognized product information.

If it is determined in step S314 that the article corresponding to the recognized product information has been purchased, the controller of the mobile terminal 200 may transmit information on the currently purchased article to the refrigerator 100 S316). For example, the purchased article information transmitted to the refrigerator 100 in step S316 may be the product information of the article indicated by the purchase.

Meanwhile, the refrigerator 100 may receive the purchased article information transmitted from the mobile terminal 200. Then, the database of the corresponding article can be updated based on the received purchased article information (S318). Accordingly, in step S318, the database of the goods corresponding to the received information may further include product information on the currently purchased goods, and the latest purchase date and quantity of the goods may be changed based on the purchased article information have.

Meanwhile, FIG. 4 is a flowchart illustrating an operation of calculating a remaining consumption period based on a purchase history of a currently recognized product by the refrigerator 100 according to an embodiment of the present invention.

Referring to FIG. 4, when the product information is received from the mobile terminal 200 in step S302 of FIG. 3, the controller 110 of the refrigerator 100 according to the embodiment of the present invention responds to the received product information The purchase history information for the predetermined period can be extracted from the database of the goods (S400).

Here, the predetermined period may be a period from the day when the purchase of the article corresponding to the product information occurred before the nth to the current date based on the current date.

That is, when the item corresponding to the currently received product information is 'milk', and when the user's purchase of 'milk' is as shown in [Table], if the predetermined number n is '3' , It may be determined that the first day of the 12/1 period in which the 'milk' purchase occurred before the third day based on the current date. Accordingly, the purchase history of the 'milk' from the 12/1 to the present (12/7) can be extracted in the step S400.

date 12/1 12/2 12/3 12/4 12/5 12/6 12/7 Purchase quantity 2 2 - - One - (Now)

On the other hand, if the purchase history information is extracted in step S400, the controller 110 may calculate the total quantity (or total capacity) of the products purchased during the predetermined period. The consumption period per unit of reference of the article corresponding to the currently received product information can be calculated from the calculated total quantity (or total capacity).

Here, the 'unit standard' may be a reference unit preset by a user for an article corresponding to the product information. Or the unit criterion may be determined according to the unit in which the user normally purchases the article. Here, the unit criterion may be determined according to a unit in which the user purchases the product most or a unit that purchases the article on average, as a result of analyzing the article database.

For example, when the user purchases the 'milk', if the user purchases the milk with the 900 ml capacity as the largest unit, the control unit 110 determines that the user has purchased the milk unit 900 ml capacity One milk "can be judged. Or the item is an 'egg'. If the user purchases 10 eggs each, 10 eggs can be used as the unit standard of the 'egg'.

Meanwhile, the 'per-unit-per-unit consumption period' may be a period in which the period from the purchase history to the next purchase is divided by the unit basis for the predetermined period. That is, assuming that the user purchases 900 ml of 'milk' as shown in the above table, since the user purchases the milk again on 12/2 the next day after two milk is purchased on 12/1 where the first purchase occurred , The consumption period per unit standard based on the initial purchase may be one day / two, that is, 0.5 days per unit. On the other hand, since 2 milk was purchased on 12/2 of the second purchase, and the user purchased milk again on 12/5 after 3 days, the consumption period per unit standard based on the initial purchase is 3 days / 2 It can be 1.5 days per one.

On the other hand, in the case of 12/5 where the next purchase occurred, since the 'milk' purchase has not occurred at present, the consumption period per unit standard may not be calculated.

On the other hand, if consumption periods per unit standard are calculated each time a purchase of the article occurs for a preset period based on the current date, the controller 110 calculates an average consumption period (S402). For example, according to the example shown in [Table], when the consumption periods per unit basis (0.5 days, 1.5 days) are calculated for each purchase, the controller 110 calculates the average consumption period ((0.5 + 1.5) / 2 = 1). Accordingly, the average consumption period of the 'milk' can be calculated according to a purchase pattern in which the user purchases 'milk' during the predetermined period.

On the other hand, when the average consumption period is calculated as described above, the control unit 110 multiplies the quantity (or capacity) of the most recently purchased goods by the user before the current date with the average consumption period calculated in step S404, (S404). For example, in the case of the example shown in the table above, the date of the most recent milk purchase before 12/7 is 12/5, and one is purchased. Accordingly, the control unit 110 can calculate the consumable period calculated in step S404 as '1 day'.

If it is determined in step S404 that the consumable period is calculated, the controller 110 may calculate the remaining consumption period by subtracting the period from the most recent purchase of the product to the current time (S406). That is, in the case of the example shown in the above table, since the date of the most recent milk purchase before 12/7 is 12/5, the period from the most recent purchase date to the present day is 2 days The control unit 110 may calculate the remaining consumption period as -1 day (1 - 2 = -1) because the presently calculated consumption period is '1 day'. In this case, the control unit 110 can determine that the remaining consumption period is less than '0', and thus purchase of the article is necessary.

5, the refrigerator 100 according to the embodiment of the present invention determines whether or not to recommend the purchase of the product based on the remaining consumption period and the price information of the product, FIG. 5 is a flowchart showing the operation of the step in more detail.

5, the controller 110 of the refrigerator 100 according to the embodiment of the present invention calculates the remaining consumption period in step S306 of FIG. 3 (for example, And extract price information from the product information received from the mobile terminal 200. [ Then, the control unit 110 may determine whether the calculated remaining consumption period is less than a predetermined first threshold period (S500). If the remaining consumption period is not less than the first threshold period as a result of the determination, it may be determined that the article corresponding to the recognized product information is not currently needed (S514). On the other hand, if the remaining consumption period is less than the first threshold period, it can be determined that the article corresponding to the recognized product information is presently needed (S502).

For example, the first threshold period may be a period arbitrarily set by a user with a value of '0' or more. For example, the first threshold period may be set to '1'. If the calculated remaining consumption period is less than one day, the controller 110 proceeds from step S500 to step S502 and determines that the article corresponding to the recognized product information is necessary. If the calculated remaining consumption period is less than one day The process proceeds from step S500 to step S514 and it can be determined that the article corresponding to the recognized product information is not necessary.

On the other hand, if it is determined that the article corresponding to the recognized product information is necessary (S502), the controller 110 can extract price information from the product information (S504). Then, the price of the article according to the extracted price information and the average value of the article can be compared with each other (S506).

Here, the average value of the goods may mean an average price of the goods purchased by the user for a preset period of time corresponding to the recognized product information. Alternatively, the control unit 110 may connect with a predetermined external server or network, collect price information of the goods corresponding to the recognized product information, and calculate an average value from the collected price information. Or directly receive the average value of the article from the external server.

If the price of the article according to the extracted price information is less than or equal to the average value of the article as a result of the price comparison in step S506, the controller 110 may determine to recommend purchasing the article corresponding to the recognized article information (S508).

On the other hand, if it is determined in step S506 that the price of the article according to the extracted price information exceeds the average value of the article, the controller 110 determines whether the recognized product information (Step S510). In other words, the controller 110 proceeds to step S510, and if it is determined that the current remaining consumption period is equal to or less than 0 day, the controller 110 may proceed to step S508 and determine that the purchase of the article corresponding to the recognized product information is recommended have. That is, when the current price of the product is high, the control unit 110 may enable the user to purchase the product only when necessary. Accordingly, if it is determined in operation S510 that the current remaining consumption period exceeds '0 day', the controller 110 may determine that the purchase of the article corresponding to the recognized product information is not recommended (S512 ).

The step S510 may further include determining whether the price of the article is equal to or greater than a second threshold value. Here, the second threshold may be a value obtained by multiplying the highest price among the prices of the goods purchased by the user corresponding to the recognized product information by one or more numbers (for example, 1.3) Lt; / RTI > If the price of the article is equal to or higher than the second threshold value, the control unit 110 may not recommend purchasing the article even if the current consumption period calculated at step S510 is equal to or less than '0 day' . That is, when it is judged that the price of the current product is higher than the predetermined maximum price, it may not recommend the purchase of the product even if it is judged to be necessary at present.

On the other hand, if it is determined in step S500 that the remaining consumption period is not less than the preset first threshold period (or more), the controller 110 proceeds to step S514 and determines that the article is not currently needed . Then, the control unit 110 can extract price information from the currently received product information (S516). Then, the price of the article according to the extracted price information and the preset first threshold value may be compared with each other (S518).

Here, the first threshold value is calculated by multiplying the lowest price among the prices of the goods purchased by the user corresponding to the recognized product information by a number of 1 or less (for example, '0.8') for a predetermined period It can be price. If the price of the article is less than or equal to the first threshold value, the control unit 110 may proceed to step S508 and determine to recommend the purchase of the article corresponding to the recognized product information. That is, even if it is determined that the article corresponding to the currently recognized product information is not needed, if the product price is determined to be less than the preset lowest price, .

On the other hand, if it is determined in step S518 that the price of the article according to the extracted price information exceeds the preset first threshold value, the controller 110 proceeds to step S512 to determine whether the article corresponding to the recognized product information You can decide not to recommend a purchase. That is, when the controller 110 determines that the article corresponding to the currently recognized product information is not needed, the controller 110 can recommend the purchase to the user only when the product price is lower than a predetermined level.

The step S518 may further include a step of determining whether the currently calculated residual consumption period is equal to or greater than a predetermined second threshold period. The second threshold period may be a period arbitrarily set by the user. Alternatively, the second threshold period may be a period calculated by multiplying the average consumption period calculated in FIG. 4 by one or more.

If the current remaining consumption period is equal to or longer than the second threshold period, the controller 110 may not recommend purchasing the article even if the article price extracted from the product information is lower than the first threshold value. That is, when it is determined that the remaining consumption period of the article corresponding to the currently recognized product information is sufficient, the controller 110 may not recommend the purchase of the article even if it is determined that the article price is less than a predetermined level have.

On the other hand, if it is determined in step S508, S512 or S520 that the article is recommended, the controller 110 proceeds to step S310 in FIG. 3 to transmit the currently determined purchase recommendation to the mobile terminal 200 .

According to the above description, the refrigerator 100 according to the embodiment of the present invention collects information of another selling place selling an article corresponding to the recognized product information, based on a request transmitted from the mobile terminal 200 And to transmit the collected information to the mobile terminal 200. [

6 is a view showing in more detail an operation process of the refrigerator 100 according to the embodiment of the present invention collecting information on other sellers of the currently recognized product and transmitting the collected information to the mobile terminal 200 to be.

Referring to FIG. 6, the controller 110 of the refrigerator 100 according to the embodiment of the present invention can acquire position information of the mobile terminal 200 (S600). For example, when the mobile terminal 200 transmits the product information recognized from the identification code to the refrigerator 100, the mobile terminal 200 may transmit the measured information of the current position of the mobile terminal 200 together. The control unit 110 of the refrigerator 100 may receive the location information of the mobile terminal 200 together with the recognized product information.

Meanwhile, when the location information of the mobile terminal 200 is acquired in step S500, the controller 110 may search for other sale sites located within a preset distance around the location of the mobile terminal 200. [ Here, the other selling place may be another offline selling place selling the article corresponding to the recognized product information. The control unit 110 may obtain price information of the goods corresponding to the recognized product information from each searched retailer (S602).

If the goods price information is obtained from each sales person in the vicinity of the mobile terminal 200 in step S602, the control unit 110 may generate map information indicating the location of each sales person including the obtained price information (S604 ). Here, the map information may include route information and distance information from the current location of the mobile terminal 200 to the location of each sales person.

Meanwhile, when the map information is generated in step S604, the generated map information may be transmitted to the mobile terminal 200 (S606). More preferably, the map information may be transmitted together with the article purchase recommendation result determined through step S508, S512, and S520 of FIG. Accordingly, the mobile terminal 200 displays the article purchase recommendation result received from the refrigerator 100 on the display unit 210, and displays the location and price information of the other sellers according to the user's selection, Map information including information on the display unit 210 can be displayed. An example in which the mobile terminal 200 displays information on other salespersons received from the refrigerator 100 on the display unit 210 will be described in more detail with reference to FIG.

Meanwhile, in step S602, the control unit 110 may collect not only price information but also information related to an event to be performed by each vendor. The control unit 110 may generate map information further including the event information collected in step S604. In this case, the retailer including the event information can be displayed on the map information separately from the other retailers, and the mobile terminal 200 can display the event information included in the map information on the display unit 210 Can be displayed. An example in which the mobile terminal 200 displays the sales information including the event information separately from other sellers and displays the event information according to the user's selection will be described in more detail with reference to FIG. .

Meanwhile, although FIG. 8 illustrates an example in which the refrigerator 100 collects and transmits information on other sellers around the location of the mobile terminal 200 based on the location information received from the mobile terminal 200, The present invention is not limited thereto. That is, it is needless to say that the controller 110 of the refrigerator 100 may collect the information of the other selling place located around the predetermined position of the mobile terminal 200 and transmit it to the mobile terminal 200.

For example, the particular point may be points that the user pre-designated, such as " home " or " company ". When the user designates specific points in advance, the controller 110 can acquire and store position information of the designated points.

5, when the mobile terminal 200 determines whether to recommend the purchase of the article corresponding to the product information recognized by the mobile terminal 200, It is possible to search for other sale places located within a predetermined distance around the position of each of the specific points. The control unit 110 can obtain price information and event information of the goods corresponding to the recognized product information from each searched retailer. And generate map information including information of other salespersons located around the specific points. The map information generated by the specific points may be transmitted to the mobile terminal 200 along with the purchase recommendation decision result.

Then, the mobile terminal 200 may display the map information of the point according to the user's selection among the specific points on the display unit 210. [ Then, route information and distance information from the selected point to the other sales points, sales price of each of the other sale destinations, and information related to the event in the case of the sales person proceeding with the event are transmitted to the mobile terminal 200 And can be displayed on the display unit 210. [ 8 and 9, an example in which not only the current location of the mobile terminal 200 but also information of other retailers searched based on specific points preset by the user is displayed will be described in detail.

In the above description, the information collected from the offline shoppers located at the current position of the mobile terminal 200 or around the preset specific points is described, but the present invention is not limited thereto. That is, the refrigerator 100 may collect price information from online retailers selling goods corresponding to the currently recognized product information, and may transmit the collected price information to the mobile terminal 200 together with information of each online retailer. In this case, the information of the online merchants may be displayed on the display unit 210 of the mobile terminal 200 together with the information of the offline merchants.

In the above description, the refrigerator 100 according to the embodiment of the present invention receives the product information recognized by the mobile terminal 200, and determines the result of determining whether or not to recommend the purchase of the article corresponding to the received product information, And transmits the product information to the mobile terminal 200 in response to the product information, with reference to a plurality of flowcharts.

In the following description, it is assumed that the mobile terminal 200 transmits the recognition result of the product information to the refrigerator 100, and determines whether or not to recommend the purchase of the article corresponding to the product information according to the information received from the refrigerator 100 Examples of display will be described with reference to a plurality of examples.

7 is a diagram illustrating an example in which a result of a determination by the refrigerator 100 of whether a product recognized through the mobile terminal 200 is recommended is displayed through the mobile terminal 200 according to an embodiment of the present invention. .

For example, the user can activate the predetermined application or the like to sense the image 702 through the scan unit of the mobile terminal 200. [ 7, when the identification code 700 is included in the sensed image 702, the product information can be recognized from the result of scanning the identification code 700. [ 7, the currently scanned identification code 712 and the currently recognized product information 712 can be displayed on the display unit 210 of the mobile terminal 200. As shown in FIG.

7, when the product information is recognized through the identification code, the recognized product information may be transmitted to the refrigerator 100 connected to the mobile terminal 200. [ Then, the refrigerator 100 can analyze the purchase pattern of the user for the article based on the database of the article corresponding to the received product information. Then, based on the analyzed purchase pattern of the user, it is possible to calculate the average consumption period, which is a period during which the user consumes the goods on average. Based on the calculated average consumption period and the latest purchase history of the goods, It can be judged whether it is necessary or not. The mobile terminal 200 can determine whether to recommend the purchase of the goods corresponding to the product information recognized by the mobile terminal 200 based on the price information included in the received product information. The determined purchase recommendation result may be transmitted from the refrigerator 100 to the mobile terminal 200.

Then, the mobile terminal 200 may display a purchase recommendation result 720 for the goods corresponding to the product information, as shown in the third diagram of FIG. In this case, the purchase recommendation result 720 may include a details menu 722 that allows the user to further confirm other information analyzed to calculate the purchase recommendation result. When the user selects the detailed information menu 722, as shown in the fourth diagram of FIG. 7, the refrigerator 100 determines whether or not to recommend the purchase, Various information analyzed from the database of articles can be displayed on the display unit 210. [

[ Herein, the information of other salespersons that are searched based on the position of the mobile terminal 200 may be information on the location of the mobile terminal 200, which is transmitted together when the mobile terminal 200 transmits the recognized product information to the refrigerator 100 Based on the information, the refrigerator 100 may be collected according to a result of searching for other sales places located within a certain distance.

In this case, the mobile terminal 200 can display the positions of other sales people around the current position. 8D, the position of the B convenience store 826 and the A store 824 around the K-mat 822 is displayed on the display unit (not shown), for example, 210). ≪ / RTI > In the vicinity of each of the sellers 824 and 826, price information for selling the goods corresponding to the product information at the seller can be displayed. From the current position of the mobile terminal 200, that is, from the 'K-mat' 822 And route information to each of the sellers 824 and 826 may be displayed. Each path information may further include distance information.

According to the above description, when the refrigerator 100 according to the embodiment of the present invention transmits the information of the other selling place to the mobile terminal 200, if there is a selling place where the event is proceeding, And further information related to the event can be transmitted. Accordingly, when the mobile terminal 200 displays the information related to the other sellers on the display unit 210, the mobile terminal 200 can display the sellers for the events separately from the other sellers.

FIG. 9 is an exemplary diagram illustrating an example in which the mobile terminal 200 provides event information of the other retailer provided from the refrigerator 100, according to an embodiment of the present invention.

First, referring to the first drawing of FIG. 9, the first diagram of FIG. 9 shows an example of a case where the user selects sales shop information 813 based on a predetermined point 'home' from the sales shop information menu screen 810 It is. In such a case, the mobile terminal 200 may receive other merchants (F-mart 902, G-convenience store 904) that sell articles corresponding to the currently recognized product information, Can be displayed on the display unit 210. [

In this case, the G convenience store 904 may be in a state where the current event is proceeding. 9, the mobile terminal 200 can display the G convenience store 904 differently from other retailers, that is, the F shopping mall 902. In this case, For example, the mobile terminal 200 may display notification information 906 related to the event around the G convenience store 904.

Meanwhile, the mobile terminal 200 may sense an input of a user applied to the notification information 906. 9, when the touch input of the user is applied to the notification information 906 displayed in the vicinity of the G convenience store 904, the mobile terminal 200 stores the G convenience store 904 (see FIG. 9) 904 may display on the display unit 210 information related to the event.

If there is an input by the user for the preset area 1002, the controller 110 can select any one of the purchased items from the user. The second diagram of FIG. 11 shows an example in which 'milk' is selected by the user, among the purchased products.

On the other hand, as shown in the second diagram of FIG. 11, when the user selects a specific item, the control unit 110 can display the result of analyzing the price information on the currently selected item on the display unit 150 have. For example, the controller 110 can display the result of analyzing the price of each of the currently selected products, i.e., the products included in 'milk', on the display unit 150 as shown in the third drawing of FIG. 11 have.

For example, the control unit 110 may extract a list of products purchased by the user from the database of the currently selected item 'milk'. Then, information on the current price of each of the extracted products can be searched through a predetermined external server or a connected network. Alternatively, the control unit 110 may collect price information of each of the extracted products from sellers around specific points (e.g., 'home' or 'company') preset by the user. Based on the collected price information, the average price of each of the extracted products can be calculated and the average price information 1112 of each of the calculated products can be displayed.

On the other hand, as shown in the third diagram of FIG. 11, in a state in which the average price information 1112 for each product is displayed, the controller 110 can sense an input of a user applied to a specific product. When the user inputs the specific product, the display unit 150 may display the price change information for the selected product. The fourth diagram in Fig. 11 shows this example.

For example, the control unit 110 calculates an average price for the 'A milk' for each predetermined period, and displays information 1122 including the average prices calculated for each period, so that the price for the 'A milk' Can be displayed.

On the other hand, the prices for each period for the currently selected product may be the purchase price for which the user purchased the product. If the user selects 'A milk' as in the above example, the controller 110 determines whether the user has purchased the 'A milk' from the purchase history information of the currently selected product, that is, 'A milk' Information and information about each purchase date can be extracted. Then, based on the extracted purchase date and purchase price information, information 1122 indicating the fluctuation state of the purchase price for the currently selected specific product, i.e., 'A milk' is displayed as shown in the fourth drawing of FIG. 11 You may.

In the above description, one mobile terminal is connected to the refrigerator 100. However, it is needless to say that the number of mobile terminals connected to the refrigerator 100 may be plural. In this case, when the user's behavior related to the purchase of a specific article is detected from each mobile terminal, each mobile terminal can transmit information of the purchased articles to the refrigerator 100. [ And the refrigerator 100 can update the database of articles corresponding to the received purchased article information each time the information of the purchased article is received. Accordingly, when the first user of the mobile terminal (first mobile terminal) connected to the refrigerator 100 purchases the article, the recent purchase history of the article can be updated on the database according to the purchase of the article. In this case, the consumable period of the article can be newly calculated according to the update of the recent purchase history.

On the other hand, when a second user of another mobile terminal (second mobile terminal) connected to the refrigerator 100 confirms whether or not to recommend the purchase of the same article on the same day, the product information recognized by the second mobile terminal May be transmitted to the refrigerator (100). Then, the refrigerator 100 can calculate the remaining consumption period based on the current date and the recent purchase history of the article corresponding to the product information. In this case, since the date of the latest purchase of the article is 'today' according to the purchase of the first user, the period subtracting the current date from the latest purchase date of the article may be 0 day.

On the other hand, the consumable life period (calculated by multiplying the quantity (or capacity) of the article purchased by the first user and the average consumption period) analyzed from the database of the article is greater than the calculated average consumption period , The residual consumption period may have a value larger than the average consumption period. Accordingly, the refrigerator 100 may determine that the article is not currently needed (step S514 of FIG. 5), and therefore may not recommend purchasing the present article. In response to the transmitted product information, the refrigerator 100 may transmit to the second mobile terminal information indicating that the purchase of the corresponding item is not performed.

In the above description, the mobile terminal 200 recognizes the product information according to the scanned identification code, but the present invention is not limited thereto. For example, the mobile terminal 200 may transmit only the image scanned with the identification code to the refrigerator 100, and in this case, the refrigerator 100 may recognize the product information from the received image.
