The refrigerator 51 is configured to communicate with the router device 55 via the wireless repeater 36 and the gateway device (relay device) 54, receives a signal transmitted from the router device 55, and receives the received signal from the refrigerator 51. It transmits to the wireless device 39 of the imaging unit 35 set inside. Based on this signal, the camera 38 of the imaging unit 35 set in the refrigerator 51 is configured to execute an imaging operation.

  The wireless repeater 36 also transmits the identification information (for example, the serial number and model number) of the wireless repeater itself, the image data in the warehouse to be described later, and the like to the router device 55 via the gateway device (relay device) 54. Configured as follows.

  As described above, the display terminal 15 is a general-purpose portable terminal such as a smartphone or a tablet PC (personal computer). In the present embodiment, the display terminal 15 is detachable from the door 10 of the refrigerator 51 described above. It has a function (means) for connecting to a public communication network 56 such as the Internet and a function (means) for communicating with a gateway device 54 described later.

  The display terminal 15 (for example, a smartphone) is configured to be connected to a public communication network 56 such as the Internet via a telephone line network (for example, a 3G line network). In addition or alternatively, for example, the display terminal 15 is configured to be connected to a public communication network 56 such as the Internet via a public wireless LAN by a Wi-Fi communication function.

  By connecting to the public communication network 56 such as the Internet, for example, the display terminal 15 transmits the image data acquisition program for the ingredients in the refrigerator that is the subject of the present invention via the public communication network 56 such as the Internet. It can be obtained from the manufacturer's website. By installing the acquired program on the display terminal 15 and starting the installed program, the display terminal 15 can acquire image data and the like of ingredients in the refrigerator. That is, the display terminal 15 can generate and transmit an instruction signal for acquiring the image data of the refrigerator 51 by operating the operation screen of the display 15a.

  The gateway device 54 is further configured to be connectable to a public communication network 56 such as the Internet via the router device 55. As a result, the gateway device 54 can communicate with the display terminal 15 (second communication) via the public communication network 56 such as the Internet and the router device 55 and can also communicate with the server device 57.

  Therefore, the gateway device 54 communicates with the display terminal 15 via the public communication network 56 such as the Internet and the communication not via the public communication network 56 such as the Internet (that is, the first communication via only the router device 55). (That is, the second communication via the public communication network 56 such as the Internet and the router device 55). The reason for this configuration is to enable speedy communication using the first communication when the user is in the house and the public communication network 56 such as the Internet is congested.

  The server device 57 is prepared by a manufacturer of the refrigerator or the imaging unit 35, for example. The server device 57 manages information and the like necessary for access and authentication regarding the display terminal 15 and the wireless repeater 36. For example, the server device 57 determines whether or not the identification information of the display terminal 15 included in the communication request signal matches the identification information of the display terminal 15 stored and registered in association with the wireless repeater 36. Is authenticated (discriminated). And when these correspond, the display device 15 to access is authenticated as a regular display terminal, and communication with the imaging unit 35 provided in the refrigerator 51 in the residence A is permitted.

  The server device 57 stores the image data of the ingredients in the refrigerator transmitted from the imaging unit 35 as described above. This image data is transmitted to the display terminal 15 based on a data call signal from the display terminal 15. In other words, the user can confirm the food image data in the refrigerator by operating the display terminal 15 on the display.

Of course, when a data call signal is transmitted from the display terminal 15 in the absence of a signal for requesting prior transmission of image data, the latest image data stored in the data storage unit 67 is transmitted to the display terminal 15.

  The data storage unit 67 stores necessary data such as a management program and an application program for executing the refrigerator system. Further, the data storage unit 67 rewrites and stores the latest data of the food image data transmitted from the imaging unit 35 with the addition of time information in accordance with the control of the server control unit 66. The data storage unit 67 is configured by, for example, an HDD (Hard Disc Drive), an SSD (Solid State Drive), or the like.

  The server device 57 can be constructed by either a server composed of a single large computer or a cloud server composed of a large number of computers.

<2. Operation>
Next, the operation of the refrigerator and the refrigeration system configured as described above will be described. In the following descriptions, the same operations are described with the same step numbers added.

  In this system, the inside of the storage room is imaged by the camera 38 of the imaging unit 35 attached in the storage room of the refrigerator. This imaging is performed when the door is opened or closed to put in or out the food, or the user operates the display terminal 15. This is done when an image is instructed.

  The operation will be described with reference to the flowchart of FIG.

  First, when the user opens the door 10 for taking in and out the food (step 1-Y), the door opening / closing detection unit 61 detects this and the interior lamps 34-1 and 34-2 in the storage room are turned on. (Step 2). When the storage room has an illuminance of a predetermined level or higher (step 3-Y), the illuminance detection unit 40 of the imaging unit 35 detects this, and the camera 38 images the storage room (step 4). This image data is transmitted from the wireless device 39 of the imaging unit 35 to the server device 57 via the wireless repeater 36 provided on the door 10, the gateway device (relay device) 54, the router device 55, and the public communication network 56 such as the Internet. (Step 5) and stored in the data storage unit 67 of the server device 57 (Step 6). Then, when there is a request for pre-transmission of image data so that an image can be confirmed quickly even if the public communication network 56 such as the Internet is congested from the display terminal 15 (step 7-Y), it is stored in the server device 57. The processed image data is transmitted to the display terminal 15 (step 8), and the image data is stored in the display terminal 15 (step 9).

  On the other hand, when the user does not open and close the door for putting in and out the food, but the user operates the display terminal 15 to check the food storage status in the storage room from the shop where the food is purchased, etc., an imaging instruction is transmitted (step 10-Y), the wireless device 39 of the imaging unit 35 receives this via the public communication network 56 such as the Internet, the router device 55, the gateway device (relay device) 54, and the wireless repeater 36, and the power supply unit 42 In operation, the illumination device 41 of the image pickup unit 35 is turned on (step 11), and power is supplied to the camera 38 to image the inside of the storage room (step 4). Thereafter, the same operation as after imaging when the door is opened and closed is performed.

  Further, the image data transmitted as described above is reproduced and confirmed on the display terminal 15.

  FIG. 14 shows a flowchart of normal image display in a warehouse. The user arbitrarily sets the display period or date / time of the in-store image to be displayed from the display terminal 15 and performs an image acquisition operation on the display terminal 15. For example, a prior transmission request is made from the display terminal 15 and an in-store image is acquired within a specified period. The flow of image data acquisition is as shown in FIG. The internal image is stored in the display terminal 15 (step 12), and the display terminal 15 confirms the presence or absence of image data within a specified period from the stored image (step 13), and the image data is time-sequentially stored. Is output to the display unit of the display terminal 15 (step 14). When the user presses the playback button, the image data read in time series on the display unit of the display terminal 15 is automatically switched (step 15), and is continuously displayed by displaying. As for the timing of image switching, image switching is performed after the display time has elapsed or when there is an image feed operation by the user (step 16-Y). The image feed operation by the user can be viewed while skipping the image by the time width by pressing the feed button displayed on the display terminal 15 or using a seek bar. This makes it possible to search for images in the warehouse by specifying the date and time, and to continuously browse images in the time series, greatly reducing the time required for image search, and by using a seek bar, It becomes possible to find the target image effectively.

  FIG. 15 shows a flowchart in the case of detecting the change in the internal image and continuously reproducing the internal image. The image data is stored in the display terminal 15 and output to the display unit (step 21), and the user traces the displayed image in the cabinet with his / her finger to specify the food material or the region in the cabinet (step 22). By doing this, the specific area between the image displayed last time and the image currently displayed is compared (step 23), and if there is an image feed operation by the user (step 16-Y), the image is switched ( Step 15) When the change is detected, the automatic reproduction is stopped (Step 24). As a result, users can easily know changes in the specific area in the warehouse or the presence or absence of food by performing automatic playback without checking image data one by one, making inventory management easy. Can do. Furthermore, by designating a specific area, the amount of image change detection processing can be reduced, and a constant processing speed can be maintained. Note that it is preferable that the control unit 59 of the refrigerator or the server control unit 66 of the server device 57 detects the presence or absence of the change by comparing specific areas of the previous display image and the current display image.

  As described above, the refrigerator and the refrigerator system according to the embodiment of the present invention can confirm the storage status of foodstuffs by the display terminal 15 as described above with a specific configuration. Therefore, it is easy to use because an imaging device such as a camera can be installed at a preferred position, and communication between the imaging device 38 provided in the refrigerator and the public communication network 56 is also appropriately performed via the wireless repeater 36. Since it can be performed, the refrigerator which can also confirm the foodstuff accommodation state in a refrigerator favorably can be provided.

  That is, the refrigerator is configured such that the imaging unit 35 in which the camera 38, the wireless device 39, and the power supply unit 42 are integrated is configured independently of the refrigerator main body 1 and the door 10, and is mounted in the storage chamber 5 of the refrigerator. In addition, since the wireless repeater 36 that communicates with the wireless device 39 of the imaging unit 35 is separately provided and the wireless repeater 36 is attached to the refrigerator body 1 or the door 10, the user is required. Accordingly, the image pickup unit 35 independent of the refrigerator main body 1 and the door 10 can be installed in a favorite place (place to see) in the storage room 5. Moreover, even if the wireless device 39 is surrounded by the metal exterior plate constituting the refrigerator body 1 and the door 10 by providing the imaging unit 35 in the storage chamber 5, the wireless device 39 of the imaging unit 35. And the public communication network 56 can be relayed by the wireless repeater 36 to establish communication appropriately. That is, when the wireless repeater 36 performs wireless communication with the wireless device 39 of the image pickup unit 35, the wireless repeater 36 communicates with the first wireless communication method using radio waves having a frequency that allows good wireless communication even when a metal plate or the like is interposed. The wireless communication with the public communication network 56 such as the Internet is performed by the second communication method such as WI-FI wireless communication that can perform good wireless communication even if there is a distance. This makes it possible to secure good communication.

  And since the said radio repeater 36 is set as the structure provided in the position which does not oppose the vacuum heat insulating material 4a provided in order to improve heat insulation, the vacuum heat insulating material 4a is used for the refrigerator main body 1 or the door 10, and the Even when the jacket material is made of a metal film or the like, communication can be established with higher accuracy, and both reliability and improved heat insulation (energy saving) can be achieved.

  In addition, since the wireless repeater 36 is provided in the vicinity of the rotation instruction portion of the door 10 in this embodiment, the impact received when the door 10 is closed is reduced, and the durability is improved. Even if it is provided, the reliability can be enhanced.

  Furthermore, since the imaging unit 35 is configured to supply power from the power supply unit 42 to the camera 38 when the wireless device 39 receives a wireless radio wave, the imaging unit 35 captures an image only when the radio wave is received. Become. Accordingly, the power consumption is remarkably reduced compared to the case where power is continuously supplied to the camera 38 and imaging is continued, and the life of the imaging unit 35 can be extended. In particular, since the imaging unit 35 uses an independent power source such as a battery, extending the life is a very important requirement, which is a great effect.

  Further, the imaging unit 35 includes an illuminating device 41 that illuminates the storage chamber 5 and is configured to supply power to the illuminating device 41 when the wireless device 39 receives a wireless radio wave. Since the illumination device 41 is lit when receiving and taking an image, the inside of the storage chamber 5 can be taken well. Further, since the imaging unit 35 itself can be illuminated, it is not necessary to change the illumination control on the refrigerator side, and the burden on the refrigerator side is reduced.

  The imaging unit 35 includes an illuminance detection unit 40 that detects the illuminance in the storage chamber 5, and supplies power to the camera 38 from the power supply unit 42 when the illuminance detection unit 40 detects a predetermined illuminance or higher. Therefore, when the door 10 is opened and the food is taken in and out, the interior lamps 34-1 and 34-2 are turned on and detected by the illuminance detection unit 40, and the camera 38 is supplied with power and stored. Image indoors. In other words, it is possible to take an image at the door opening / closing timing (timing at which the illuminance in the cabinet changes), and it is possible to reliably image the storage state after the food is put in and out performed by the door opening / closing.

  In addition, the food storage state in the refrigerator can be achieved by providing a refrigerator system including the refrigerator 51 provided with such an imaging unit 35 and the display terminal 15 that performs communication between the wireless repeater 36 of the refrigerator 51. It can be known from the outside, and convenience is improved.

  Furthermore, the present invention can wirelessly communicate with the imaging unit 35 in which the camera 38, the wireless device 39, and the power supply unit 42 are integrated, and the wireless device 39 of the imaging unit 35, and can also communicate with the public communication network 56. An imaging set 37 including a wireless repeater 36 is provided. Therefore, even if it is a general refrigerator which does not have a communication function by this, it can be set as the refrigerator which has a communication function by installing the said imaging set 37. FIG. Therefore, the user purchases a general refrigerator, or purchases and installs the imaging set 37 as necessary in a refrigerator currently in use to make a so-called internet home appliance with a communication function. And the value of the refrigerator can be dramatically improved.

  In addition, the wireless repeater 36 of the imaging set 37 has two types, a first wireless communication method for communicating with the wireless device 39 of the imaging unit 35 and a second wireless communication method for wirelessly communicating with the public communication network. It has a wireless communication system, and the frequency of the radio wave that communicates with the radio device 39 of the imaging unit 35 is higher than the frequency of the radio wave that communicates with the public communication network 56. Thereby, even if the refrigerator main body 1 and the metal exterior plate of the door 10 which are easy to block a radio wave between the radio | wireless apparatus 39 and the radio repeater 36 of the imaging unit 35 can ensure favorable communication, inside a refrigerator It is possible to provide a refrigerator that can surely check the state of storage of food ingredients.
