The video control unit 31 and the wireless communication unit 32 are housed in the substrate installation space 24, and are disposed between the portion of the heat insulating material 8 located on the rear side of the substrate installation space 24 and the operation unit 23. That is, the wireless communication unit 32 and the operation unit 23 are housed in the same substrate installation space 24.

Moreover, as shown in FIG. 3, the opening and closing door 3 has the vacuum heat insulating material 40 formed in the flat shape. The vacuum heat insulating material 40 has, for example, a glass material 41 as a plate-like base member having a heat insulating property inside a vacuum portion, and an aluminum foil 42 coated as a metal covering the surface of the glass material 41.

It is larger than the wireless communication unit 32 and the substrate installation space 24. Thereby, the aluminum foil 42 is configured such that electromagnetic shielding is provided between the wireless communication unit 32 and the refrigerating compartment 100. In the present embodiment, the aluminum foil 42 is used as the metal member for shielding the wireless communication unit 32 from the refrigerator compartment 100. However, the present invention is not limited thereto, and the metal member may be formed of, for example, metal. The wire, the mesh material, the powder body, and the like are mixed into the glass material 41 of the vacuum heat insulating material 40.

Next, the operation of the refrigerator 1 will be described. First, when the coolers 10 and 11 When the blower fan 12 is operated, the cooling air generated by the coolers 10 and 11 is blown to the refrigerating compartment 100, the switching compartment 200, the ice making compartment 300, the freezing compartment 400, and the vegetable compartment 500. Thereby, each chamber is cooled to a temperature set by, for example, the operation portion 23. Further, when the refrigerator 1 is in operation, the image acquisition unit 30 captures 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 panel 21 of the opening and closing door 3 to the external information receiving unit.

Here, since the outer panel 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 penetrated to the outside. With this configuration, even when the wireless communication unit 32 is placed inside the opening and closing door 3 in consideration of the design consideration of the refrigerator 1, it is possible to suppress communication due to metal parts or the like disposed in the casing 2 and the opening and closing door 3. obstacle.

Electromagnetic shielding is formed between the wireless communication unit 32 and the refrigerating compartment 100.

Thereby, the communication wave emitted from the wireless communication unit 32 to the rear side can be reflected forward by the aluminum foil 42, and the communication wave can be suppressed from reverberating in the refrigerator compartment 100 without contributing to communication with the information receiving unit. Therefore, the wireless communication unit 32 can be disposed inside the casing 2 (more specifically, inside the opening and closing door 3), and at the same time, the communication wave is concentrated toward the outside of the casing 2, and the design of the refrigerator 1 can be improved.

Thereby, the operation unit 23 and the image control unit are provided The work of installing the 31 and the wireless communication unit 32 inside the opening and closing door 3 can be concentrated in one place and efficiently performed. As a result, the number of programs for assembling the refrigerator 1 is reduced, and the work is simplified.

Further, by providing the video control unit 31 and the wireless communication unit 32 on the same substrate 33, the communication quality between the video control unit 31 and the wireless communication unit 32 can be improved. Further, compared with the case of the wireless communication unit 32 in which the independent device is disposed, the area of the substrate 33 can be increased, and the performance of the substrate 33 as a radiation element that radiates communication waves can be improved.

In addition, the vacuum heat insulating material 40 can suppress the heat from being transmitted from the image control unit 31 and the wireless communication unit 32 (both of which are easily heat-generating parts) to the refrigerating compartment 100, and can stably maintain the temperature of the refrigerating compartment 100. Further, in the present embodiment, since the aluminum foil 42 constitutes a part of the vacuum heat insulating material 40, heat shielding and electromagnetic shielding between the image control unit 31 and the wireless communication unit 32 and the refrigerating chamber 100 can be realized with a single component. . Thereby, the number of parts of the refrigerator 1 can be reduced, the cost reduction can be promoted, and workability at the time of assembly can be further improved.

Further, the wireless communication unit 32 is disposed inside the opening and closing door 3 among the wall surfaces of the casing 2. In general, in order to ensure the opening and closing function of the door, an obstacle is not placed on the front side of the opening and closing door 3. Therefore, according to the present embodiment, it is possible to avoid a structure in which communication failure is caused between the wireless communication unit 32 and the external information receiving unit, and the communication quality can be improved. Further, since the wireless communication unit 32 is disposed in the intermediate portion in the wide direction when viewed from the front side of the refrigerator 1, even when the refrigerator 1 is installed indoors, even one of the side portions 2A and 2B and the indoor portion are provided. When the wall faces are adjacent to each other, a certain distance can be secured between the wireless communication unit 32 and the wall surface of the room. Thereby, regardless of the layout of the refrigerator 1 How to maintain the quality of communication in a stable manner.

In addition, the video acquisition unit 30 and the wireless communication unit 32 are connected to each other by the communication line 34, and the vacuum heat insulating material 40 containing the metal material is placed between the video acquisition unit 30 and the wireless communication unit 32. It is also possible to communicate via a path that does not pass through the vacuum heat insulating material 40. Further, since the image acquisition unit 30 and the wireless communication unit 32 are disposed in the same opening/closing door 3, the length of the communication line 34 can be shortened as much as possible. Therefore, the communication quality between the video acquisition unit 30 and the wireless communication unit 32 can be ensured.

In the present embodiment, the image acquisition unit 30 including a photographing camera or the like is disposed as a detecting unit for detecting the situation in the refrigerating compartment 100, and the image captured in the refrigerating compartment 100 is wirelessly communicated. The portion 32 is transmitted to the outside. Thereby, the user can check the situation in the refrigerator compartment 100 by using an image such as a information terminal (not shown) without opening the door 3, for example. As a result, it is possible to shorten the time required to open the opening and closing door 3 in order to confirm the cold collection, and it is possible to suppress an unnecessary temperature rise in the refrigerator 1. In addition, when a wireless communication terminal or the like that can bring out a home is used as an information terminal, when the user goes shopping, the stored contents in the refrigerator compartment 100 can be checked outside. Thereby, it is possible to suppress the mistake of forgetting to buy or repeat buying, and it is possible to improve the convenience of the user.
