(advertisement picture display processing; FIG. 3)
Next, an advertisement screen display process performed by the above-described refrigerator system 1 will be described. Fig. 3 is a flowchart of the advertisement screen display process. The advertisement screen display processing is started, for example, when the power of the refrigerator 2 is turned on. As shown in fig. 3, in S10 of the advertising screen display process, the control section 20 of the refrigerator 2 determines whether the first sensor 41 has detected the person M (e.g., the user of the refrigerator 2) present within the range of the first distance L1 with respect to the refrigerator main body 40. When the first sensor 41 detects the person M present within the range of the first distance L1, a first detection signal is transmitted from the first sensor 41 to the control unit 20. When receiving the first detection signal, the control unit 20 determines YES in S10 and proceeds to S11. When the first detection signal is not received, the control unit 20 determines NO (NO) in S10 and stands by.
In the next S11, the control part 20 determines whether the second sensor 42 detects the person M present in the range of the second distance L2 with respect to the refrigerator main body 40. When the second sensor 42 detects the person M present within the range of the second distance L2, a second detection signal is transmitted from the second sensor 42 to the control unit 20. When the control unit 20 receives the second detection signal, the determination at S11 is yes, and the process proceeds to S13. On the other hand, if the second detection signal is not received, the control unit 20 determines in S11 no and proceeds to S12.
If yes in S10 and no in S11, the person M is present in the range of the first distance L1 with respect to the refrigerator main body 40, but is not present in the range of the second distance L2 with respect to the refrigerator main body 40.
In S12 after no in S11, the controller 20 displays a predetermined advertisement screen in the center of the operation display unit 24. The control unit 20 displays 1 or more advertisement screens on the operation display unit 24. The control unit 20 displays an advertisement screen on the operation display unit 24 based on the advertisement information stored in the storage unit 21. For example, as shown in fig. 4, the control unit 20 displays a carrot advertisement screen D1, a pork advertisement screen D2, or the like in the center of the operation display unit 24. The center of the operation display unit 24 is the center in the lateral direction and/or the center in the vertical direction of the operation display unit 24. After the process at S12 shown in fig. 3 is completed, the process returns.
On the other hand, in S13 following S11, the controller 20 displays a predetermined advertisement screen on the peripheral edge of the operation display unit 24. The control unit 20 displays 1 or more advertisement screens on the operation display unit 24. The control unit 20 displays an advertisement screen on the operation display unit 24 based on the advertisement information stored in the storage unit 21. For example, as shown in fig. 5, the control unit 20 displays a carrot advertisement screen D1, a pork advertisement screen D2, and the like on the peripheral edge of the operation display unit 24. The peripheral edge of the operation display unit 24 is a portion around the central portion of the operation display unit 24.
When the process of S13 shown in fig. 3 is executed and the process of S13 is executed after the process of S12 is executed, the control unit 20 displays the advertisement screens D1 and D2 (see fig. 4) displayed on the center portion of the operation display unit 24 in S12 and displays the advertisement screens D13 (see fig. 5) on the peripheral portion of the operation display unit 24 in S13.
In S13, control unit 20 displays a predetermined operation button for executing the function of refrigerator 2 in the center of operation display unit 24. The control unit 20 displays 1 or more operation buttons on the operation display unit 24. For example, as shown in fig. 5, the controller 20 displays a cold storage button B1, a freeze button B2, an ice making button B3, and a power saving button B4 in the center of the operation display unit 24. For example, the cold storage button B1 is a button for setting the cold storage temperature of the refrigerator 2, and the freeze button B2 is a button for setting the freeze temperature of the refrigerator 2. Further, the ice making button B3 is a button for setting on/off of the ice making function of the refrigerator 2, and the power saving button B4 is a button for setting on/off of the power saving function of the refrigerator 2. The kind of the operation buttons for performing the functions of the refrigerator 2 is not particularly limited. In S12, the controller 20 does not display the operation buttons B1-B4 for executing the functions of the refrigerator 2 on the operation display unit 24 (see fig. 4). The control unit 20 ends the process at S13 and returns to the step.
Then, the control unit 20 repeatedly executes the above-described advertisement screen display process. The above-described advertisement screen display processing is terminated when the power of the refrigerator 2 is turned off, for example.
(specific conditions)
Next, a specific situation will be described. In the above-described refrigerator system 1, as shown in fig. 1, when the person M (user of the refrigerator 2) is not present within the range of the first distance L1 with respect to the refrigerator main body 40 and the person M is present outside the range of the first distance L1 with respect to the refrigerator main body 40, neither the first sensor 41 nor the second sensor 42 detects the person M. In this case, as shown in fig. 3, the control unit 20 of the refrigerator 2 determines no in S10.
Then, for example, it is set as: the person M gradually approaches the refrigerator 2, and thus enters an area within the range of the first distance L1 and outside the range of the second distance L2 with respect to the refrigerator main body 40. In this case, as shown in fig. 3, the control unit 20 makes a yes judgment in S10 and a no judgment in S11, and proceeds to S12. In S12, the control unit 20 displays the advertisement screens D1 and D2 (see fig. 4) in the center of the operation display unit 24.
Then, for example, it is set as: the person M further approaches the refrigerator 2 gradually, so that the person M enters an area within a range of the second distance L2 with respect to the refrigerator main body 40. In this case, as shown in fig. 3, the control unit 20 determines yes in S10 and yes in S11, and proceeds to S13. In S13, the control unit 20 displays predetermined advertisement screens D1 and D2 (see fig. 5) on the peripheral edge of the operation display unit 24. The controller 20 displays the advertisement screens D1 and D2 displayed in the center of the operation display unit 24 in S12 described above on the peripheral edge of the operation display unit 24. In S13, controller 20 displays predetermined operation buttons B1-B4 (see fig. 5) in the center of operation display unit 24.
Then, for example, it is set as: the person M gradually gets away from the refrigerator 2 so that the person M enters an area outside the range of the second distance L2 and within the range of the first distance L1. In this case, as shown in fig. 3, the control unit 20 makes a yes judgment in S10 and a no judgment in S11, and proceeds to S12. In S12, the control unit 20 displays the advertisement screens D1 and D2 (see fig. 4) in the center of the operation display unit 24. The control unit 20 does not display the predetermined operation buttons B1-B4 in the center of the operation display unit 24.
The first embodiment has been explained above. As is apparent from the above description, in the first embodiment, when the human detection sensor 4 detects the human M existing within the range of the first distance L1 and outside the range of the second distance L2 with respect to the refrigerator main body 40, the control unit 20 displays the advertisement screens D1 and D2 in the central portion of the operation display unit 24 (yes in S10 and no in S11 in fig. 3, refer to S12 and fig. 4). When the motion detection sensor 4 detects the presence of the person M within the range of the second distance L2 from the refrigerator main body 40, the control unit 20 displays the operation buttons B1-B4 in the center of the operation display unit 24 (yes in S10, yes in S11, refer to S13 and fig. 5).
According to this configuration, when the person M (user of the refrigerator 2) is present within the range of the first distance L1 and outside the range of the second distance L2 with respect to the refrigerator main body 40, the advertisement screens D1 and D2 can be presented to the person M. Further, when the person M exists within the range of the second distance L2 with respect to the refrigerator main body 40, the operation buttons B1-B4 can be prompted. Therefore, when the person M is close to the refrigerator 2 but the person M is not close to the position where the operation display unit 24 can be operated, the advertisement screens D1 and D2 can be presented to the person M. When the person M approaches a position where the operation display unit 24 can be operated, the operation buttons B1-B4 can be presented to the person M. Thereby, appropriate information can be presented according to the distance between the refrigerator 2 and the person M (the user of the refrigerator 2).
In the first embodiment, when the human detection sensor 4 detects the presence of the human M within the range of the second distance L2 from the refrigerator main body 40, the control unit 20 displays the advertisement screens D1 and D2 originally displayed in the central portion of the operation display unit 24 on the peripheral portion of the operation display unit 24 (see S13 in fig. 3). With this configuration, when the person M approaches the refrigerator 2 to a position where the operation display unit 24 can be operated, the advertisement screens D1 and D2 can be displayed at appropriate positions.
An embodiment has been described above, but the specific manner is not limited to the above-described embodiment. In the following description, the same reference numerals are given to the same components as those described above, and the description thereof is omitted.
(second embodiment)
A refrigerator system 1 according to a second embodiment will be described. In the refrigerator system 1 according to the second embodiment, the refrigerator 2 and the mobile terminal 3 are configured to be able to perform short-range wireless communication via the communication unit 23 of the refrigerator 2 and the communication unit 33 of the mobile terminal 3. As shown in fig. 1, when the refrigerator 2 and the mobile terminal 3 approach each other within a predetermined third distance L3, the short-range wireless communication is enabled. The third distance L3 is, for example, the same distance as the second distance L2 described above. In other embodiments, the third distance L3 may also be a shorter distance than the second distance L2.
The control unit 20 of the refrigerator 2 can acquire the terminal identification information stored in the storage unit 31 of the portable terminal 3 by short-range wireless communication via the communication units 23 and 33. The terminal identification information is information for identifying the portable terminal 3. The control unit 20 can also provide the advertisement-related information stored in the storage unit 21 to the mobile terminal 3 by short-range wireless communication via the communication units 23 and 33. The advertisement-related information is information related to the advertisement screens D1 and D2 displayed on the operation display unit 24 (see fig. 4 and 5). For example, the advertisement-related information is information such as the price of carrot or the price of pork. The advertisement-related information is information such as the origin of carrot or the origin of pork. The content of the advertisement-related information is not particularly limited. The advertisement-related information is acquired, for example, by the control unit 20 from an external server (not shown) via the network 90. The advertisement-related information acquired by the control unit 20 is stored in the storage unit 21.
(advertisement-related information supply processing; FIG. 6)
Next, an advertisement-related information providing process performed by the above-described refrigerator system 1 will be described. Fig. 6 is a flowchart of the advertisement-related information providing process. The advertisement-related information supply process is started, for example, when the power of the refrigerator 2 is turned on. As shown in fig. 6, in S20 of the advertisement-related information providing process, the control unit 20 of the refrigerator 2 determines whether or not the terminal identification information of the mobile terminal 3 is acquired. When the refrigerator 2 and the mobile terminal 3 approach each other within the range of the predetermined third distance L3, the refrigerator 2 and the mobile terminal 3 are in a state in which the short-range wireless communication via the communication units 23 and 33 can be performed (see fig. 1). For example, when the person M (the user of the refrigerator 2 and the mobile terminal 3) carrying the mobile terminal 3 approaches the refrigerator 2 within the range of the third distance L3, the refrigerator 2 and the mobile terminal 3 can perform the short-range wireless communication. When the short-range wireless communication is enabled, the control unit 20 of the refrigerator 2 automatically acquires the terminal identification information stored in the storage unit 31 of the portable terminal 3. When the terminal identification information is acquired, the control unit 20 determines yes in S20 and proceeds to S21. Otherwise, in S20, the control unit 20 determines no and stands by. If the refrigerator 2 and the portable terminal 3 do not approach within the range of the third distance L3, the control unit 20 determines no in S20.
When the person M carrying the mobile terminal 3 approaches the refrigerator 2 within the range of the predetermined second distance L2, the control unit 20 displays advertisement screens D1 and D2 on the peripheral edge of the operation display unit 24 (see S13 and fig. 5 of fig. 3 of the first embodiment).
In S21 following S20 shown in fig. 6, the control unit 20 determines whether or not any of the advertisement screens D1 and D2 (see fig. 5) displayed on the peripheral edge portion of the operation display unit 24 has been touched. When a touch operation is performed on one (e.g., D1) of the advertisement screens D1 and D2, the controller 20 determines yes in S21 and proceeds to S22. For example, when the person M (the user of the refrigerator 2 and the mobile terminal 3) approaching the refrigerator 2 touches the advertisement screen D1 displayed on the peripheral edge of the operation display unit 24, the control unit 20 determines yes. On the other hand, if the touch operation is not performed on the advertisement screens D1 and D2, in S21, the controller 20 determines no and proceeds to S23.
In S23 after no in S21, the control unit 20 determines whether or not a predetermined time has elapsed after yes in S20 described above. The predetermined time is, for example, 3 minutes. When the predetermined time has elapsed, the control unit 20 determines yes at S23 and ends the advertisement-related information providing process. Otherwise, in S23, control unit 20 determines no and returns to S21.
In S22 after yes in S21, the control unit 20 determines whether or not the refrigerator 2 and the portable terminal 3 are in a state in which the short-range wireless communication via the communication units 23 and 33 can be performed. When the refrigerator 2 and the portable terminal 3 approach within the range of the third distance L3, the state is such that the short-range wireless communication can be performed between the refrigerator 2 and the portable terminal 3. If the state is such that the short-range wireless communication can be executed, the control unit 20 determines yes at S22 and proceeds to S24. Otherwise, at S22, the control unit 20 determines no and ends the advertisement-related information providing process. For example, when the person M carrying the mobile terminal 3 approaches the refrigerator 2 within the range of the third distance L3 and then moves away from the refrigerator 2 to be out of the range of the third distance L3, the control unit 20 determines no in S22.
In the next S24, the control unit 20 supplies the advertisement-related information associated with the advertisement screen (for example, D1) touched in the above-described S21 to the mobile terminal 3. The control unit 20 supplies the advertisement-related information to the mobile terminal 3 identified by the terminal identification information acquired in S20 described above. That is, the control unit 20 supplies the advertisement-related information to the portable terminal 3 existing within the range of the third distance L3 with respect to the refrigerator 2. The supplied advertisement-related information is information related to the advertisement screen (for example, D1) touched in S21 described above. For example, the advertisement-related information is information such as the price or the place of production of a carrot. As described above, the advertisement-related information providing process is ended.
(advertisement-associated information display processing; FIG. 7)
Next, the advertisement-related information display process executed by the above-described refrigerator system 1 will be described. Fig. 7 is a flowchart of the advertisement-associated information display process. The advertisement-related information display processing is started, for example, when the power of the portable terminal 3 is turned on. As shown in fig. 7, in S30 of the advertisement-related information display process, the control unit 30 of the mobile terminal 3 determines whether or not the advertisement-related information supplied from the refrigerator 2 in S24 of the above-described advertisement-related information supply process (see fig. 6) is acquired. The control unit 30 of the mobile terminal 3 can acquire advertisement-related information from the refrigerator 2 by short-range wireless communication via the communication units 23 and 33. When the advertisement-related information is acquired, the control unit 30 determines yes at S30 and proceeds to S31. Otherwise, control unit 30 determines no at S30 and waits.
In next S31, the controller 30 displays the advertisement-related information acquired in S30 on the operation display unit 34 of the mobile terminal 3. For example, as shown in fig. 8, the control unit 30 displays information (advertisement-related information) such as the price and the place of production of a carrot on the operation display unit 34.

The control unit 20 can acquire specific advertisement related information related to the specific advertisement information from an external server via the network 90. The specific advertisement-related information is information such as the price or the place of origin of milk. The control unit 20 stores the acquired specific advertisement information or specific advertisement-related information in the storage unit 21.
(specific advertisement picture display processing; FIG. 9)
Next, a specific advertisement screen display process performed by the above-described refrigerator system 1 will be described. Fig. 9 is a flowchart of the specific advertisement screen display process. The specific advertisement screen display processing is started, for example, when the power of the refrigerator 2 is turned on. As shown in fig. 9, in S40 of the specific advertisement screen display process, the control unit 20 of the refrigerator 2 determines whether or not the terminal identification information of the mobile terminal 3 is acquired by the short-range wireless communication. When the refrigerator 2 and the mobile terminal 3 approach each other within the range of the third distance L3, the refrigerator 2 and the mobile terminal 3 are in a state in which the short-range wireless communication via the communication units 23 and 33 is executable (see fig. 1). For example, when the person M (the user of the refrigerator 2 and the mobile terminal 3) carrying the mobile terminal 3 approaches the refrigerator 2 within the range of the third distance L3, the refrigerator 2 and the mobile terminal 3 can perform the short-range wireless communication. When the short-range wireless communication is enabled, the control unit 20 of the refrigerator 2 automatically acquires the terminal identification information stored in the storage unit 31 of the portable terminal 3. When the terminal identification information is acquired by the short-range wireless communication, the control unit 20 determines yes in S40 and proceeds to S41. Otherwise, in S40, the control unit 20 determines no and stands by. If the refrigerator 2 and the portable terminal 3 do not approach within the range of the third distance L3, the control unit 20 determines no in S40.
In next S41, the control unit 20 displays a specific advertisement screen in the central portion of the operation display unit 24. The control unit 20 displays 1 or more specific advertisement screens on the operation display unit 24. The control unit 20 displays a specific advertisement screen on the operation display unit 24 based on the terminal identification information, the order history information, and the specific advertisement information stored in the storage unit 21. More specifically, the control unit 20 compares the terminal identification information acquired in S40 with the terminal identification information stored in the storage unit 21, and extracts the terminal identification information that matches the terminal identification information acquired in S40 from the storage unit 21. The terminal identification information acquired in S40 is the terminal identification information acquired by the control unit 20 from the mobile terminal 3 by short-range wireless communication. The terminal identification information stored in the storage unit 21 is terminal identification information supplied from the portable terminal 3 having the associated application installed to the refrigerator 2 via the network 90.
Next, the control unit 20 extracts, from the storage unit 21, order history information of the portable terminal 3 specified from the terminal identification information extracted from the storage unit 21. In addition, the control unit 20 similarly extracts specific advertisement information associated with the subscription history information extracted from the storage unit 21. The order history information is, for example, information for determining that 1 milk box was ordered one week ago. The specific advertisement information is, for example, information of an advertisement for milk. In S41 shown in fig. 9, the control unit 20 displays a specific advertisement screen in the central portion of the operation display unit 24 based on the specific advertisement information extracted from the storage unit 21. For example, as shown in fig. 10, the control unit 20 displays a milk-specific advertisement screen E1 in the central portion of the operation display unit 24.
As shown in fig. 9, at next S42, the controller 20 determines whether or not the specific advertisement screen E1 (see fig. 10) displayed at the center of the operation display unit 24 has been touched. When the specific advertisement screen E1 is touched, the controller 20 determines yes in S42 and proceeds to S43. For example, when the person M (the user of the refrigerator 2 and the mobile terminal 3) approaching the refrigerator 2 touches the specific advertisement screen E1 displayed in the center of the operation display unit 24, the control unit 20 determines yes. On the other hand, if the specific advertisement screen E1 is not touched, the controller 20 determines no in S42 and proceeds to S44.
In S44 after no in S42, the controller 20 determines whether or not a predetermined time has elapsed after the specific advertisement screen E1 is displayed on the operation display unit 24 in S41 described above. The predetermined time is, for example, 3 minutes. When the predetermined time has elapsed, the control unit 20 determines yes in S44 and proceeds to S46. Otherwise, in S44, control unit 20 determines no and returns to S42.
In S46 following S44, the controller 20 erases the specific advertisement screen E1 originally displayed on the operation display unit 24. Therefore, the specific advertisement screen E1 is no longer displayed on the operation display portion 24. Then, the control unit 20 ends the specific advertisement related information display processing.
In S43 following yes in S42, the control unit 20 determines whether or not the refrigerator 2 and the portable terminal 3 are in a state in which the short-range wireless communication via the communication units 23 and 33 is executable. When the refrigerator 2 and the portable terminal 3 approach within the range of the third distance L3, the state is such that the short-range wireless communication can be performed between the refrigerator 2 and the portable terminal 3. If the state is such that the short-range wireless communication can be executed, the control unit 20 determines yes at S43 and proceeds to S45. Otherwise, in S43, control unit 20 determines no and proceeds to S46. For example, when the person M carrying the mobile terminal 3 approaches the refrigerator 2 within the range of the third distance L3 and then moves out of the range of the third distance L3 with respect to the refrigerator 2, the control unit 20 determines no in S43. At S46, the controller 20 erases the specific advertisement screen E1 originally displayed on the operation display unit 24.
In S45 following S43, the control unit 20 supplies the mobile terminal 3 with the specific advertisement-related information associated with the specific advertisement screen E1 touched in S42. The control unit 20 supplies the specific advertisement-related information to the mobile terminal 3 identified from the terminal identification information acquired in S40 described above. That is, the control section 20 supplies the specific advertisement-related information to the portable terminal 3 existing within the range of the third distance L3 with respect to the refrigerator 2. The supplied specific advertisement-related information is information related to the specific advertisement screen E1 touched at S42 described above. For example, the specific advertisement-related information is information such as the price or the origin of milk. As a result, the specific advertisement-related information display processing is ended.
(specific advertisement-associated information display processing; FIG. 11)
Next, a specific advertisement-related information display process performed by the above-described refrigerator system 1 will be described. Fig. 11 is a flowchart of specific advertisement associated information display processing. The specific advertisement-associated information display processing is started, for example, when the power of the portable terminal 3 is turned on. As shown in fig. 11, in S50 of the specific advertisement-related information display processing, the control unit 30 of the mobile terminal 3 determines whether or not the specific advertisement-related information supplied from the refrigerator 2 in S45 of the specific advertisement-related information display processing (see fig. 9) described above has been acquired. The control unit 30 of the mobile terminal 3 can acquire specific advertisement-related information from the refrigerator 2 by short-range wireless communication via the communication units 23 and 33. When the specific advertisement-related information is acquired, control unit 30 determines yes at S50 and proceeds to S51. Otherwise, control unit 30 determines no at S50 and waits.
At next S51, the controller 30 displays the specific advertisement-related information acquired at S50 on the operation display unit 34 of the mobile terminal 3. For example, as shown in fig. 12, the control unit 30 displays information (specific advertisement related information) such as the price and the place of production of milk on the operation display unit 34. In S51, the control unit 30 stores the acquired specific advertisement-related information in the storage unit 31 of the mobile terminal 3.
