  Next, the operation of the refrigerator 1 will be described. First, when the coolers 10 and 11 and the blower fan 12 are operated, the cooling air generated by the coolers 10 and 11 is blown into the refrigerating room 100, the switching room 200, the ice making room 300, the freezing room 400, and the vegetable room 500. . Thereby, each chamber is cooled to the temperature set in the operation part 23, for example. Further, when the refrigerator 1 is operated, the image acquisition unit 30 captures an image of the state in the refrigerator compartment 100. The captured image is subjected to image processing by the image control unit 31 and then transmitted from the wireless communication unit 32 through the outer plate 21 of the opening / closing door 3 to the external information receiving unit.

  Here, since the outer plate 21 is formed of a non-metallic material such as a glass material, the communication wave of the wireless communication unit 32 can be smoothly transmitted to the outside. Thereby, even in a state where the wireless communication unit 32 is arranged inside the opening / closing door 3 in consideration of the design of the refrigerator 1, communication failure due to metal parts and the like arranged on the housing 2 and the opening / closing door 3 is suppressed. be able to. Moreover, in the present embodiment, the vacuum heat insulating material 40 having the aluminum foil 42 is disposed on the rear surface side of the wireless communication unit 32, and the projected area of the aluminum foil 42 with respect to the plane perpendicular to the front-rear direction is larger than that of the wireless communication unit 32. The wireless communication unit 32 is electromagnetically shielded from the refrigerator compartment 100 by being formed large.

  Thereby, the communication wave transmitted to the rear side from the wireless communication unit 32 can be reflected forward by the aluminum foil 42, and this communication wave does not contribute to the communication with the information receiving unit and is reflected in the refrigerator compartment 100. Can be suppressed. Accordingly, communication waves can be concentrated toward the outside of the housing 2 while the wireless communication unit 32 is installed inside the housing 2 (more specifically, inside the opening / closing door 3). The designability and the communication property can be improved.

  In the present embodiment, the image control unit 31 and the wireless communication unit 32 are arranged on the same substrate 33, and the substrate 33 and the operation unit 23 are accommodated in the same substrate installation space 24. The vacuum heat insulating material 40 is disposed between the substrate 33 and the refrigerator compartment 100.

As a result, the number of steps of assembling the refrigerator 1 can be reduced and the work can be simplified.

  Furthermore, by installing the image control unit 31 and the wireless communication unit 32 on the same substrate 33, the communication quality between the image control unit 31 and the wireless communication unit 32 can be improved. Moreover, compared with the case where the radio | wireless communication part 32 is arrange | positioned independently, the area of the board | substrate 33 can be enlarged and the performance of the board | substrate 33 as a radiation element which radiates | emits a communication wave can be improved.

  Further, heat conduction from the image control unit 31 and the wireless communication unit 32, which are components that easily generate heat, to the refrigerator compartment 100 is suppressed by the vacuum heat insulating material 40, and the temperature of the refrigerator compartment 100 can be stably maintained. . In addition, in this embodiment, since a part of the vacuum heat insulating material 40 is constituted by the aluminum foil 42, the thermal cutoff between the image control unit 31 and the wireless communication unit 32 and the refrigerator compartment 100, and the electromagnetic The blocking can be realized by one component. Thereby, the number of parts of the refrigerator 1 can be reduced, cost reduction can be promoted, and workability during assembly can be further improved.

  The wireless communication unit 32 is disposed inside the open / close door 3 in the wall surface of the housing 2. In general, an obstacle is often not placed on the front side of the opening / closing door 3 in order to ensure the opening / closing function of the door.

Moreover, since the radio | wireless communication part 32 is arrange | positioned in the intermediate part of the width direction seeing from the front side of the refrigerator 1, when the refrigerator 1 is installed indoors, any of side part 2A, 2B is adjacent to the wall surface of a room | chamber interior Even in this case, a certain distance can be secured between the wireless communication unit 32 and the wall surface in the room. Thereby, communication quality can be stably maintained irrespective of the layout of the refrigerator 1.

  Further, even when the image acquisition unit 30 and the wireless communication unit 32 are wired to each other through the communication line 34, the vacuum heat insulating material 40 including a metal material is disposed between the image acquisition unit 30 and the wireless communication unit 32. Communication is possible through a route that does not pass through the vacuum heat insulating material 40. Moreover, since the image acquisition unit 30 and the wireless communication unit 32 are arranged in the same opening / closing door 3, the length of the communication line 34 can be shortened as much as possible. Therefore, communication quality between the image acquisition unit 30 and the wireless communication unit 32 can be ensured.

  Furthermore, in the present embodiment, an image acquisition unit 30 including an imaging camera or the like is arranged as a detection unit that detects the situation in the refrigerator compartment 100, and an image captured in the refrigerator compartment 100 is externally transmitted by the wireless communication unit 32. It is set as the structure which transmits to. Thereby, even if the user does not open the open / close door 3, the user can confirm the situation in the refrigerator compartment 100 with an image using an information terminal (not shown), for example. As a result, it is possible to shorten the time that the open / close door 3 is opened in order to check a refrigerated product, and to suppress an unnecessary temperature rise in the refrigerator 1. Further, when a wireless communication terminal or the like that can be taken out of the house is used as the information terminal, the stored items in the refrigerator compartment 100 can be confirmed at the destination when the user performs shopping. Thereby, it is possible to suppress mistakes such as forgetting to buy or duplicate buying, and to improve user convenience.
