  FIG. 2 is a side view showing an upper portion of the refrigerator 1 of FIG.

  As shown in FIGS. 1 and 2, the refrigerator 1 has cameras 12C, 13C, 14C, 15C, and 16C, which are image acquisition means, respectively. Each of the cameras 12C, 13C, 14C, 15C, and 16C is, for example, a CCD (charge coupled device) camera, and is accommodated in the refrigerating chamber 12, the vegetable chamber 13, the switching chamber 14, the freezing chamber 15, and the ice making chamber 16, respectively. It is supposed to take pictures of the contained goods. The cameras 12C, 13C, 14C, 15C and 16C are preferably disposed on the inner surface of the left door 21 and the drawer-type doors 23, 24, 25 and 26, but the arrangement location of each camera is not particularly limited.

  As shown in FIGS. 1 and 2, the left door 21 incorporates a control operation unit (also referred to as a control operation board) 30 for changing the cooling control content of the refrigerator 1 and the communication unit 100. ing. In this example, in the left door 21, the communication unit 100 is disposed below the control operation unit 30. Inside the left door 21, a storage box 31 of the control operation unit and a storage box 101 for communication means are disposed.

  The control operation unit 30 is disposed in the storage box 31 of the control operation unit. The storage box 31 of the control operation unit is disposed on the back side of the front plate 21A of the left door 21. The operation buttons 30A, 30B, 30C and the home button 30H of the control operation unit 30 disposed in the storage box 31 of the control operation unit operate the function of the refrigerator by the touch operation of the user's finger from the surface of the front plate 21A. For operation, it is a capacitive button (e.g. electrostatic switch electrode).

  For example, the control operation unit 30 detects an infrared light receiving unit for detecting an environmental state around the refrigerator, each operation button 30A, 30B, 30C, the home button 30H, a touch on the home button 30H, and an operation button name, An LED indicator for transparently displaying a cooling function name, a cooling intensity and the like, and a 7-segment LED display device and the like for transparently displaying a changing numerical value such as a temperature value are provided.

  Thus, the user visually checks the stored items contained in the respective refrigerating compartments 12, vegetable compartments 13, switching compartments 14, freezing compartments 15, and ice making compartments 16 using a portable terminal, an image display device, etc. can do.

  As shown in FIG. 1 and FIG. 2, the communication unit 100 is stored in a storage box 101 for communication means. The storage box 101 for communication means is disposed on the back side of the front plate 21A of the left door 21, for example, at a position below the storage box 31. Communication unit 100 can also be called an information communication unit adapter (IT unit adapter).

  Thus, the communication unit 100 is housed in the storage box 101 for communication means, which is arranged in advance inside the front plate 21A of the left door 21, so that the communication unit 100 is accommodated inside the front plate 21A of the left door 21. It can be compactly stored at a predetermined position.

  The communication unit 100 is disposed on the inner side of the front plate 21A of the left door 21. Therefore, the communication unit 100 is disposed to protrude from the outer wall (outer surface) of the top of the cabinet 11 or the outer wall (outer surface) of the door. Therefore, the communication unit need not be provided on the top outer wall (outer surface) or the door outer wall (outer surface). Moreover, since the communication unit 100 is disposed inside the front side of the left door 21, there is nothing to block radio waves during wireless communication by the communication antenna of the communication unit 10.

  FIG. 3 shows an example of how the control operation unit 30 is stored in the storage box 31 of the control operation unit and how the communication unit 100 is stored in the storage box 101 for communication means.

  In the example of FIG. 3A, the storage box 31 of the control operation unit and the storage box 101 for communication means are separate members. Thus, the control operation unit 30 is stored in the storage box 31 of the control operation unit, but the communication unit 100 may be stored in the storage box 101 for communication means different from the storage box 31 of the control operation unit. it can.

  Further, since the storage box 31 of the control operation unit and the storage box 101 for communication means can be separate members, the layout of the communication unit 100 can be facilitated when the communication unit 100 is disposed inside the left door 21. For example, the storage box 101 for communication means can be disposed at a position separated from the storage box 31 of the control operation unit.

  On the other hand, in the example shown in FIG. 3B, the storage box 31 of the control operation unit and the storage box 101 for communication means are integrated, and are configured as one storage box member 39. Thus, the control operation unit 30 and the communication unit 100 can be stored in one integrated storage box 39. By using one storage box 39, the number of parts can be reduced.

  3A and 3B, the control / operation unit 30 and the communication unit 100 store the control / operation unit from the opening 41 on the end surface 21T side of the left door 21 in the vertical direction. It can be inserted into the box 31 and the storage box 101 for communication means, and can be stored in the storage box 31 of the control operation unit and the storage box 101 for communication means.

  The communication unit 100 shown in FIG. 4 has a communication board 110 and a case 111. A communication antenna 120 and a connector (also referred to as a slot) 131 for inserting and connecting an information storage medium 130 such as a semiconductor memory card are mounted on the communication substrate 110. The format of the information storage medium 130 is not particularly limited. As the information storage medium 130, one based on various data storage standards such as an SD memory card can be adopted, and it has a communication function including an antenna. It is good. The communication antenna 120 is a printed wiring antenna formed linearly in the communication substrate 110.

  The case 111 shown in FIG. 4 is made of plastic, and has an upper case portion 111A and a lower case portion 111B. The communication substrate 110 is accommodated between the upper case portion 111A and the lower case portion 111B and fixed by screws 111C, but the connector (also referred to as a slot) 131 is exposed to the outside from the case 111.

  By arranging the communication antenna 120 and the connector (also referred to as a slot) 131 at a position near the end face 21T of the left door 21 as described above, the communication antenna 120 is, for example, a hole formed in the end face 21T of the left door 21. Wireless transmission and reception can be facilitated by performing wireless transmission and reception with the outside through the (or thin portion) 21H.

  Further, by arranging the connector (also referred to as a slot) 131 at a position near the end face 21T of the left door 21, the information storage medium 130 can be inserted into or removed from the connector 131 of the communication board 111 through the hole 21R. You can do it easily.

  In the refrigerator according to the first embodiment of the present invention described above, the control operation unit 30 and the communication unit 100 as communication means are prevented from protruding as a convex portion from the outer wall (outer surface) of the left door 21 of the refrigerator. For this reason, since the front part of the left door 21 can be made smooth, the glass-made front plate 21A can be used. Therefore, the external appearance of the refrigerator can be improved and the outside size can be reduced.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIGS. 6 and 7.

  In the first embodiment of the present invention described above, as shown in FIG. 3, a storage box 101 for communication means is disposed inside the front plate 21A of the left door 21. Then, a communication unit 100 as communication means constituted by the case 111 and the communication substrate 110 is stored as it is in the storage box 101 for communication means.

Are disposed in the storage box 201 of FIG.

  FIG. 6 shows an example of how the control operation unit 30 is stored in the storage box 31 of the control operation unit, and how the communication board 110 is stored in the storage box 201 for communication means.

  In FIG. 6A, the storage box 31 of the control operation unit and the storage box 201 for communication means are separate members. Thus, the control operation unit 30 is stored in the storage box 31 of the control operation unit, but the communication board 110 may be stored in the storage box 201 for communication means different from the storage box 31 of the control operation unit. it can. For example, the storage box 201 for communication means can be disposed at a position separated from the storage box 31 of the control operation unit.

  On the other hand, in FIG. 6 (B), the storage box 31 of the control operation unit and the storage box 201 for communication means are integrated into one storage box member 139. Thus, the control operation unit 30 and the communication substrate 110 can be stored in one integrated storage box 139. By using one storage box 139, the number of parts can be reduced.

  6A and 6B, the control operation unit 30 and the communication substrate 110 store the control operation unit from the opening 41 on the end surface 21T side of the left door 21 in the vertical direction. It can be inserted into the box 31 and the storage box 201 for communication means, and can be stored in the storage box 31 of the control operation unit and the storage box 201 for communication means.

  Moreover, as shown in FIG. 7, in either case of FIG. 6A and FIG. 6B, the communication antenna 120 and the connector (also referred to as a slot) 131 are formed on the left door 21 in the communication substrate 110. It is preferable to arrange at a position near the end face 21T.

  Thus, the communication antenna 120 and the connector (also referred to as a slot) 131 are disposed at a position near the end face 21T of the left door 21, and the communication antenna 120 is, for example, a hole formed in the end face 21T of the left door 21. Wireless transmission and reception can be facilitated by performing wireless transmission and reception with the outside through the (or thin portion) 21H.

  Further, by arranging the connector (also referred to as a slot) 131 at a position near the end face 21T of the left door 21, inserting or removing the information storage medium 130 from the connector 131 of the communication board 111 through the hole 21R. Can be done easily.

  FIG. 8 is a side view with a partial cross section of the left door 21 showing the example of FIG. 6 (A).

  As shown in FIG. 8, inside the left door 21, a storage box 31 of the control operation unit and a storage box 201 for communication means are arranged. A translucent cover member 290 is attached to the front side of the storage box 31 of the control operation unit and the storage box 201 for communication means.

  In this example, the storage box 31 of the control operation unit and the storage box 201 for communication means are disposed at the upper and lower positions along the Z direction, but the invention is not limited thereto. The storage box 201 for communication means can also be disposed at the left and right positions along the X direction. The X direction and the Z direction are orthogonal to each other.

  In the example shown in FIG. 9A, the communication substrate 110 is stored in the storage box 201 for communication means, but the communication antenna 120 is on the front side of the communication substrate 110 and the inner surface of the cover member 290. It is fixed to Thus, the communication antenna 120 can facilitate wireless transmission and reception by performing wireless transmission and reception with the outside.

  FIG. 9B shows a structural example in which the communication antenna 120 is fixed to the inner surface of the cover member 290. A protective film 292 is attached to the surface of the nonmetal plate member 291 of the cover member 290, and the communication antenna 120 is attached to the inner surface of the plate member 291. The communication antenna 120 is connected to the communication substrate 110 shown in FIG. 9A by a vapor deposition film 292 made of metal.

  FIG. 10A shows the case where the hole HL is opened at the position of the communication substrate 110 corresponding to the communication antenna 120. In FIG. 10B, the communication antenna 120 of the communication substrate 110 is opened. The example of the part of a corresponding position is shown being formed thinly compared with other parts.

  In FIG. 10A, the hole HL is open at the position of the communication substrate 110 corresponding to the communication antenna 120. Thus, the communication antenna 120 can easily transmit a radio wave, and can easily transmit and receive with the outside. Further, in FIG. 10B, the portion 127 at the position corresponding to the communication antenna 120 of the communication substrate 110 is formed thinner than the other portions. Thus, the communication antenna 120 can easily transmit a radio wave, and can easily transmit and receive with the outside.

  11 shows an example in which the control operation unit (also referred to as a control operation board) 30 is disposed on the inner surface side of the left door 21, that is, on the inside of the cabinet, and the communication substrate 110 is disposed on the front plate 21A side of the left door 21. It shows. Thereby, the user can perform the operation in the control operation unit 30 when the left door 21 is opened.

  12 and 13 show an arrangement example of the mounted elements in the communication board 110. FIG. The communication substrate 110 is disposed in parallel at a distance from the inner surface 21 N of the front plate 21 A of the left door 21.

  In the example illustrated in FIG. 12A, the connector 131, the control unit 177, and the communication antenna 120 are disposed on the front surface 110F of the communication substrate 110. As described above, the communication antenna 120 is linearly formed on the communication substrate 110. However, for example, a protective member is used to prevent the communication antenna 120 from adhering to the inner surface of the front plate 21A made of glass. 128 are disposed between the communication antenna 120 and the inner surface 21N of the front plate 21A.

  This prevents the communication antenna 120 from being directly affected by the expansion or contraction of the front plate 21A. For example, if the communication antenna 120 is hit against the front plate 21A, communication can not be performed, and this is to prevent this. The protective member 128 is also a position regulating member for preventing the communication antenna 120 from coming close to and contacting the glass front plate 21A.

  Further, the thickness t1 of the connector 131 and the thickness t2 of the control unit 177 are larger than the thickness t3 of the communication antenna 120.

  In the example illustrated in FIG. 12B, the connector 131 and the control unit 177 are disposed on the front surface 110F of the communication substrate 110. However, the communication antenna 120 is disposed on the back surface 110B of the communication substrate 110 so as not to be in close contact with the inner surface 21N of the front plate 21A made of glass. This prevents the communication antenna 120 from being directly affected by the expansion or contraction of the front plate 21A.

  In the example shown in FIG. 13, the connector 131, the control unit 177, and the communication antenna 120 are disposed on the back surface 110B of the communication substrate 110, but the electrostatic switch electrode 199 is disposed on the front surface 110F. As a result, when the user touches the front plate 21A with the finger HT, the capacitance of the electrostatic switch electrode 199 changes, so that various inputs can be performed using the electrostatic switch electrode 199.

  FIG. 14 is a perspective view showing an example of the communication substrate 110 and the storage box 201 for communication means.

  The storage box 201 has a rectangular insertion port 21 M on the end face 21 T side of the left door 21. The communication board 110 is inserted and stored in the storage box 201 through the insertion opening 21M, and the insertion opening 21M can be closed by the lid member 219. The lid member 219 has a hole 220 for radio wave passage. The communication antenna 120 is disposed at a position near the hole 220 on the communication substrate 110. Thus, the communication antenna 120 can easily perform transmission and reception with the outside through the hole 220 of the lid member 219 without any problem.

  15 to 17 show another example of the communication board 110. FIG.

  In the example shown in FIG. 15, the communication substrate 110 has a first substrate unit 110P and a second substrate unit 110R. The first substrate unit 110P and the second substrate unit 110R of the communication substrate 110 are accommodated in a storage box 201 for communication means.

  As shown in FIG. 15, an electrostatic switch electrode 199 is disposed on the surface of the first substrate portion 110P, and a through hole 199H is formed at a position corresponding to the electrostatic switch electrode 199 of the first substrate portion 110P. ing. The second substrate unit 110R is disposed parallel to the rear side of the first substrate unit 110P. An LED (light emitting diode) 110E as a light source for illumination and a communication antenna 120 are disposed on the surface of the second substrate unit 110R. The LED 110E is disposed immediately behind the through hole 199H.

  Thereby, the light of LED110E can illuminate the electrostatic switch electrode 199 from the back through the through-hole 199H by lighting LED110E. Therefore, when the user touches the front plate 21A with the finger HT to operate the electrostatic switch electrode 199, the user can easily visually check the position of the electrostatic switch electrode 199 by illumination from behind.

  As shown in FIG. 15, the communication antenna 120 is disposed at a position near the lid member 219 and is close to the hole 220 of the lid member 219. Thus, the communication antenna 120 can reliably transmit and receive with the outside through radio waves through the hole 220.

  In the example shown in FIG. 16, the electrostatic switch electrode 199 is disposed on the front surface of the communication substrate 110, and the communication antenna 120 is disposed on the back surface. The communication antenna 120 is disposed at a position close to the lid member 219 and is close to the hole 220 of the lid member 219. Thus, the communication antenna 120 can reliably transmit and receive with the outside through radio waves through the hole 220.

  In the example shown in FIG. 17, the electrostatic switch electrode 199 and the communication antenna 120 are disposed on the surface of the communication substrate 110. The communication antenna 120 is disposed at a position close to the lid member 219 and is close to the hole 220 of the lid member 219. Thus, the communication antenna 120 can reliably transmit and receive with the outside through radio waves through the hole 220.

  In the example shown in FIG. 18, a connector (also referred to as a slot) 131 for inserting and connecting the information storage medium 130 is disposed at a position away from the communication substrate 110. The connector 131 is disposed, for example, inside the front plate 21A of the left door 21 and on the side of the end face 21G outside the left door 21. The connector 131 is electrically connected to the communication substrate 110 using the wiring 131H. Thus, there is an advantage that the user can easily insert and remove the information storage medium 130 from the side of the end face 21G on the outer side of the left door 21 to and from the connector 131. When the information storage medium 130 has a communication function including an antenna, after the information storage medium 130 is inserted into the connector, communication may be performed with the communication substrate 110 in a noncontact manner, and may also be performed with the outside.

  In the embodiment described above, the control operation unit (also referred to as a control operation board) 30 and the communication unit 100 (or the communication board 110) are housed inside the left door 21. However, the control operation unit (also referred to as a control operation board) 30 and the communication unit 100 (or communication board 110) may be accommodated inside the right door 22 instead of the left door 21.

  Alternatively, the control operation unit (also referred to as a control operation board) 30 and the communication unit 100 (or the communication board 110) can be separately disposed to both the left door 21 and the right door 22.

  Also in the refrigerator according to the second embodiment of the present invention described above, the control operation unit 30 and the communication substrate 110 as the communication means are prevented from protruding from the outer wall (outer surface) of the left door 21 of the refrigerator as a convex portion. For this reason, since the front part of the left door 21 can be made smooth, the glass-made front plate 21A can be used. Therefore, the external appearance of the refrigerator can be improved and the outside size can be reduced.

  The refrigerator 1 according to the embodiment of the present invention includes a refrigerator body having an open front, a heat insulating door attached to a front opening of the refrigerator, and communication means for communicating information with the outside, Means are arranged in the door. Thereby, it can prevent projecting from the outer wall (outer surface) of a refrigerator, the appearance on the external appearance of a refrigerator can be improved, and size reduction of outer dimensions can be achieved.

Therefore, the communication means can be prevented from protruding from the outer wall (outer surface) of the refrigerator, the appearance of the refrigerator can be improved, and the outside size can be reduced.

  The storage box for the control operation unit and the storage box for the communication means are an integrated structure, or the storage box for the control operation unit and the storage box for the communication means are separate structures. Thus, the storage box for the control operation unit and the storage box for the communication means can adopt either an integrated structure or a separate structure, and the control operation unit and the communication means can be arranged in the door. You can increase the freedom of layout.

  The communication means is constituted only by the communication substrate having the communication antenna, or constituted by the communication substrate and a case for accommodating the communication substrate. As a result, the communication means can be configured only with the communication substrate having the communication antenna, or can be configured with the communication substrate and the case for accommodating the communication substrate, as needed. be able to.

  The communication board has a connector for mounting an information storage medium, and a communication antenna, and the connector and the communication antenna are arranged on the communication board at a position close to the longitudinal end face of the door. Thus, the information storage medium can be easily attached to and detached from the connector from the end face side of the door, and the radio wave of the communication antenna can be sent from the end face side of the door.

  A glass front plate is disposed on the front of the door, and the communication antenna is disposed away from the front plate. Thereby, the communication antenna can be prevented from being chipped by the contact of the front plate.

  The communication antenna is disposed on the surface side facing the inner surface of the front plate of the communication substrate, and a protection member is disposed between the communication antenna and the inner surface of the front plate. Thus, the communication antenna can be protected from the front plate by using a protective member, the communication antenna does not hit the front plate, and the communication antenna is not chipped.

  A control unit and a connector are arranged on the side of the communication substrate on which the communication antenna is arranged, and the thickness of the control unit is larger than the thickness of the communication antenna. Thus, since the thickness of the control unit is larger than the thickness of the communication antenna, the communication antenna does not directly hit the front plate, and therefore the communication antenna is not chipped.

  In the communication substrate, the connector, the control unit, and the communication antenna are disposed on the back surface separated from the front plate, and the electrostatic switch electrode is disposed on the surface of the communication substrate facing the inner surface of the front plate. Thus, since the communication antenna is disposed on the back side away from the front plate, the communication antenna does not hit the front plate and is not chipped by the front plate. Since the electrostatic switch electrode is disposed on the surface of the communication substrate, the user can change the electrostatic capacitance of the electrostatic switch electrode and operate the switch by putting a finger on the front plate.

  The vertical end face of the door is provided with a hole through which the radio wave of the communication antenna passes. Thus, the radio wave of the communication antenna can pass through the hole of the end face, so that the communication antenna can reliably transmit and receive information with the outside.

  The opening of the storage box of the communication means is formed on the longitudinal end face of the door, and the cover has a lid member for closing the opening, and the lid is provided with a hole. Thus, the radio wave of the communication antenna can pass through the hole of the lid member, so that the communication antenna can reliably transmit and receive information with the outside.

  Since the light source for irradiating the electrostatic switch electrode with light is disposed on the communication substrate, the light of the light source can illuminate the electrostatic switch electrode, so the user can easily confirm the position of the electrostatic switch electrode visually be able to.
