[0036] 《First Implementation Mode》

[0037] Figure 1 It is a front view of the refrigerator 100 according to the first embodiment.

[0038] The refrigerator 100 is a device for storing food at low temperatures, and includes a plurality of doors such as refrigerator compartment doors 211 and 212 and a camera unit 3 (device) in addition to a housing 1. The housing 1 is composed of an outer box 11 made of metal (steel plate) and an inner box 12 made of resin (see FIG. Figure 3 ) are filled with vacuum insulation material and foamed polyurethane. It should be noted that the case where a predetermined surface processing is performed on the metal outer box 11 is also included in the matter that the outer box 11 is made of metal.

[0039] A plurality of storage rooms are provided inside the frame 1. Figure 1 In the example of the refrigerator 100, as storage rooms, a refrigerating room 21, an ice-making room 22 arranged on the left and right, an upper freezing room 23, a vegetable room 24, and a lower freezing room 25 are provided in order from top to bottom.

[0040] A plurality of openings P1 corresponding to the respective chambers are provided on the front side (front side) of the housing 1 (see Figure 4 ).like Figure 1 As shown, the refrigerator 100 includes a pair of left and right refrigerator compartment doors 211, 212 as French doors that form the refrigerator compartment 21 by blocking the opening P1 of the frame 1. The left refrigerator compartment door 211 can be hinged at the left end 211a (see Figure 4 ) is the center of rotation. It should be noted that the same is true for the refrigerator door 212 on the right side.

[0041] In addition, as a drawer-style door, in addition to Figure 1 In addition to the ice-making door 221 and the upper freezer door 231 shown, the refrigerator 100 also has a vegetable door 241 and a lower freezer door 251. For example, a vegetable container (not shown) is provided on the rear side (inner side) of the vegetable door 241. Moreover, the vegetable door 241 and the vegetable container are pulled out as a whole (the same is true for other drawer-type doors). It should be noted that Figure 1 The number and arrangement of the storage rooms shown are merely examples and are not intended to be limiting.

[0042] Although not shown, the refrigerator 100 includes a compressor, a radiator (condenser), a capillary tube (throttling mechanism), and a cooler (evaporator). The refrigerant circulates sequentially through the compressor, the radiator, the capillary tube, and the cooler, and the air in the storage room is cooled by heat exchange with the refrigerant flowing in the cooler.

[0043] The camera unit 3 (device) is provided outside the housing 1 (in the Figure 1 In the example, it is the upper side of the frame 1). It should be noted that the ice making room 22, the upper freezer 23, the vegetable room 24, and the lower freezer 25 can also be photographed by the camera unit 3. In this way, the camera unit 3 has a photographing function as a "predetermined function" different from the cooling function and the wireless communication function. Figure 1 In the example of FIG. 1 , the camera unit 3 is disposed just above the joint between the refrigerator compartment doors 211 and 212 in the closed state. However, the position of the camera unit 3 in the left-right direction may be changed as appropriate.

[0044] Figure 2 is a side view of the refrigerator 100 .

[0045] like Figure 2As shown in FIG. 1 , a lens 3a is provided near the front end of the camera unit 3. The lens 3a is used to refract light and focus it on the image sensor 3d (see FIG. 1 ). Fig. 9B ) is facing downward. As such lens 3a, for example, a fisheye lens is used.

[0046] like Figure 2 As shown, the lens 3a is arranged at a position closer to the front side than the front end of the frame 1 (the edge of the opening P1 of the frame 1). More preferably, the lens 3a is arranged at a position closer to the front side than the front surfaces of the refrigerator compartment doors 211 and 212 in the closed state. Thus, when the refrigerator compartment doors 211 and 212, the vegetable compartment door 241, and the lower freezer compartment door 251 are opened, the refrigerator compartment 21, the vegetable compartment door 241, the lower freezer compartment door 251, etc. are easily brought into the field of view of the lens 3a.

[0047] The refrigerator 100 also includes a support member 4 that supports the camera unit 3 (device). The support member 4 is interposed between the camera unit 3 and the housing 1 and is fixed to the upper surface of the housing 1.

[0048] Figure 2 The power substrate 62 shown is a substrate on which a power circuit (not shown) such as a compressor (not shown) and a fan (not shown) is installed, and is disposed at the lower part of the back side of the refrigerator 100. The in-box control substrate 63 is a substrate on which an in-box control microcomputer (not shown) for cooling control is installed, and is disposed near the middle of the vertical direction on the back side of the refrigerator 100. It should be noted that Figure 2 This is just an example, and the arrangement of the power substrate 62 and the internal control substrate 63 may be appropriately changed. For example, the internal control substrate 63 may be arranged at the lower part of the back side of the refrigerator 100. In addition, the power substrate 62 and the internal control substrate 63 may be integrated.

[0049] Figure 3 This is a front view of the refrigerator 100 in a state where the left and right refrigerating chamber doors 211, 212 are opened.

[0050] like Figure 3 As shown, a plurality of shelves 213 are provided in the cold storage room 21. A plurality of door pockets 211c for storing food and the like are provided on the inner plate 211b of the cold storage room door 211 on the left side (the same is true for the cold storage room door 212 on the right side). Furthermore, if the left and right cold storage room doors 211 and 212 are opened, the food and the like in the cold storage room 21 and the door pockets 211c and 212c are overlooked and enter the field of view of the lens 3a of the camera unit 3. For example, when at least one of the cold storage room doors 211 and 212 is opened, the cold storage room 21 and the like are photographed by the camera unit 3 (automatic photography). In addition, when the drawer door of the vegetable room door 241 and the lower freezer door 251 are opened, the vegetable room 24 and the lower freezer 25 are photographed by the camera unit 3.

[0051] Here, in the case where the camera unit 3 is used to manually photograph the refrigerating room 21 or the like according to the user's photographing timing, a photographing button 5 may also be provided. For example, as an example of manual photographing, Figure 3 As shown, the shooting button 5 can be provided one on each of the left and right refrigerator doors 211, 212, or can be provided near the handles of the sliding doors of the vegetable compartment door 241 and the lower freezer compartment door 251, or can be provided on any one of the camera unit 3 and the supporting component 4, but is not limited thereto.

[0052] Figure 4 It is a top view of a state where left and right refrigerating chamber doors 211, 212 of the refrigerator 100 are opened.

[0053] like Figure 4 As shown, hinges 211a and 212a are provided on the upper surface of the frame 1. The left hinge 211a rotatably supports the refrigerator door 211. It should be noted that the right hinge 212a is also the same.

[0054] like Figure 4 As shown, the camera unit 3 has a housing 3b. The housing 3b is a resin storage body that stores the substrate of the camera unit 3. When viewed from above, the housing 3b is in a rectangular shape that is elongated in the front-to-back direction. More specifically, the housing 3b is formed so that the length of the short side direction (left-right direction) changes in the middle of the long side direction (front-to-back direction), and the length of the short side direction of the rear portion is longer than that of the front portion. It should be noted that Figure 4 The shape of the housing 3b shown is just an example and is not limited thereto.

[0055] Figure 5 This is a perspective view when the camera unit 3 is viewed from obliquely below.

[0056] like Figure 5 As shown in FIG. 1 , in addition to the lens 3a and the housing 3b, the camera unit 3 further includes a lighting cover 3c. In addition, a circular hole (not shown) is provided on the lower surface near the front end of the housing 3b, and the lens 3a is exposed through the hole. In the housing 3b, a hole (not shown) elongated in the left-right direction is provided on the rear side of the lens 3a, and the lighting cover 3c is embedded in the hole. The lighting cover 3c is a protective cover for the light emitting portion 3e (see FIG. 1 ). Fig. 9B ) is also a light-transmitting resin component used to diffuse the light of the light-emitting portion 3e.

[0057] Figure 6 1 is a system structure diagram of the refrigerator 100 .

[0058] like Figure 6As shown, the refrigerator 100 includes a camera unit 3, an opening and closing detection unit 6, an operation unit 7, and a control unit 8. The opening and closing detection unit 6 is used to detect the opening and closing of the refrigerator door 211, 212, the vegetable compartment door 241, the lower freezer door 251, etc. (see Figure 1 ) is a door sensor for detecting the opening and closing status of each door of the refrigerator. If the signal of the opening status of each door is input to the control unit 8, the signal is transmitted to the camera / wireless communication control unit 3g of the camera unit 3 via the control unit 8. Moreover, if the shooting unit M1 detects the predetermined opening angle amount of each door such as the refrigerator door 211, 212, the predetermined opening amount of the vegetable compartment door 241, and the lower freezer compartment door 251 through image recognition, automatic shooting starts. Here, the operation unit 7 is a control panel operated by the user in a predetermined manner. For example, in addition to setting the temperature of the refrigerator 100, the control panel is also used for manual shooting buttons 5 (refer to Figure 3 ), and various settings such as pairing settings between the user's portable terminal 54 and the refrigerator 100, and are set on the refrigerator compartment doors 211, 212 (refer to Figure 3 )’s outer or inner surface.

[0059] The control unit 8 is, for example, a microcomputer, and although not shown in the figure, it is composed of electronic circuits such as a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and various interfaces. In addition, the program stored in the ROM is read out and expanded in the RAM, and the CPU executes various processes. The control unit 8 performs cooling control in a predetermined manner based on the signals input from the opening and closing detection unit 6 and the operation unit 7, and transmits a signal to the camera unit 3, thereby also controlling the timing of starting shooting.

[0060] The camera unit 3 includes an imaging unit M1, a light emitting unit 3e, a sound emitting unit 3f, a camera / wireless communication control unit 3g, and an antenna 3h. The imaging unit M1 is configured to include a lens 3a (see Fig. 9B ) and image sensor 3d (refer to Fig. 9B ). The image sensor 3d is an element that performs photoelectric conversion on the light incident through the lens 3a to generate captured image data.

[0061] The light emitting unit 3e is a light source that is turned on when the camera unit 3 is shooting, and is provided at a position in front of the refrigerator compartment doors 211 and 212 in the closed state (see also Fig. 9B As such a light emitting unit 3e, for example, an LED (Light Emitting Diode) is used. By lighting the light emitting unit 3e when photographing, the refrigerating room 21 can be photographed with appropriate brightness (see Figure 3)、door pockets 211c, 212c (refer to Figure 3 )、Vegetable compartment door 241 (refer to Figure 3 )、lower freezer door 251 (refer to Figure 3 ).

[0062] The sounding unit 3f is a buzzer that emits a predetermined sound when the camera unit 3 is shooting. When any of the door opening signals is transmitted via the control unit 8, the camera / wireless communication control unit 3g sends a signal to the image sensor 3d (see Fig. 9B ) outputs a shooting command. As a result, the captured image data is input from the image sensor 3d to the camera / wireless communication control unit 3g.

[0063] The antenna 3h is not limited as long as it can transmit and receive radio waves. For example, the types of antenna 3h include rod-shaped, wire-shaped, and planar-shaped. Here, two types of printed substrates in the case of using a planar antenna are described. The antenna 3h of this embodiment can use either a printed substrate with components mounted thereon or a printed substrate without components mounted thereon (only copper foil printing).

[0064] First, in the case of providing an antenna 3h using a printed circuit board (only copper foil printing) without components mounted thereon, on the camera control board 31 (see Fig. 9B ) is equipped with a camera control element (not shown) and a wireless communication control element (not shown), and uses an antenna 3h to transmit and receive signals from a camera / wireless communication control unit 3g as radio waves via a wiring K1.

[0065] In this case, the printed circuit board of the antenna 3h is formed only by copper foil printing, so there is an advantage that the size of the substrate can be reduced. The printed circuit board can be selected to have an antenna pattern (antenna pattern with copper foil printed on the entire surface, coil antenna pattern, sensor antenna pattern, meander antenna pattern, etc.) formed on one side or both sides according to the propagation speed.

[0066] Next, when an antenna 3h using a printed circuit board on which components are mounted is provided, the antenna 3h transmits the signal from the camera control board 31 (see Fig. 9B ) of the camera / wireless communication control unit 3g is transmitted and received via the wiring K1. The antenna 3h is equipped with a chip component with noise resistance, so even if the wiring length of the wiring K1 is extended and arranged together with the antenna 3h, there is almost no influence on the communication (see Figures 13 to 15 ). Hereinafter, the antenna 3h is sometimes referred to as a wireless communication substrate 32.

[0067] The captured image data output from the camera / wireless communication control unit 3g is radiated as radio waves from the antenna 3h (wireless communication substrate 32), and the radio waves are received by the router 51. It should be noted that the antenna 3h can be directional or non-directional, and can be either. The router 51 is a communication relay device, and sends the information received from the antenna 3h as radio waves to the server 53 via the network 52.

[0068] The server 53 performs predetermined processing on the captured image data and stores it in correspondence with the identification information of the refrigerator 100. In addition, when the server 53 receives a request signal for the image inside the refrigerator 100 from the portable terminal 54 of the user who has set the pairing, the server 53 sends the captured image data to the portable terminal 54.

[0069] Figure 7 This is a result of photographing by the camera unit and is an example of a state where image processing has not been performed.

[0070] It should be noted that in Figure 7 In the paper, the front is the top and the back is the bottom. Figure 3 Wait for the left and right to reverse. Figure 7 In the example of FIG. 1 , both the left and right refrigerator doors 211 and 212 are opened, and in addition to the refrigerator 21, the left and right door pockets 211c and 212c are also photographed. By using a fisheye lens as the camera unit 3 (refer to FIG. 1 ), the camera unit 3 can be viewed from the left and right sides of the refrigerator door 211 and 212. Figure 5 ) lens 3a, which can capture images with a wide range of field angles.

[0071] Figure 8 This is a result of imaging by the camera unit and is an example of an expanded image in a state after image processing has been performed.

[0072] For example, based on Figure 7 The shooting result is obtained by the server 53 (refer to Figure 6 ) is subjected to predetermined image processing, thereby converting it into an expanded image of each of the refrigerator room 21 and the refrigerator room doors 211 and 212 as viewed from the front. By displaying such an expanded image on the portable terminal 54 (refer to Figure 6 ), the user can clearly understand what kind of food is stored in the refrigerator compartment 21 and the refrigerator compartment doors 211 and 212.

[0073] Fig.9A It is a front view of the camera unit 3.

[0074] like Fig.9A As shown, the camera unit 3 is provided on the upper side of the support member 4. In addition, the camera unit 3 is provided near the center of the support member 4 in the left-right direction.

[0075] Fig. 9B Yes Fig.9A A cross-sectional view of the section taken along line II-II.

[0076] In addition to the above-mentioned structures, the camera unit 3 also includes a camera control board 31 and a wireless communication board 32. The camera control board 31 is a printed board on which an image sensor 3d, a light emitting unit 3e, a camera control element, and a wireless communication control element (not shown) are mounted, and is provided inside the housing 3b. Fig. 9B In the example of FIG. 1 , a camera control board 31 is provided near the front end of the housing 3b in parallel with the upper surface of the housing 3b.

[0077] The wireless communication board 32 is a printed board on which an antenna 3h is mounted, and is provided inside the housing 3b. Fig. 9B In the example, the wireless communication board 32 is arranged in such a way that its board surface is parallel to the side surface of the housing 3b.

[0078] The wireless communication board 32 is connected to the camera control board 31 via the wiring K1. More specifically, the antenna 3h mounted on the wireless communication board 32 is electrically connected to the camera control element (not shown) of the camera control board 31 via the wiring K1. Furthermore, predetermined communication is performed between the antenna 3h and the camera control element (not shown) via the wiring K1. Fig. 9B In the example of FIG. 3 , the wireless communication board 32 is arranged near the camera control board 31 in the longitudinal direction of the housing 3b. Thus, the length of the wiring K1 can be shortened and the generation of noise can be suppressed.

[0079] Although the cross-section is omitted, a hole H1 that is circular in shape when viewed from above is provided near the center of the bottom surface of the housing 3b of the camera unit 3, and a cylindrical portion C1 extends upward from the edge of the hole H1. In addition, a circular hole (symbol not shown) is also provided on the upper surface of the support member 4, and a plurality of claws 4b extend upward from the edge of the hole. When the camera unit 3 is assembled, the claws 4b that protrude radially outward enter the inner side of the cylindrical portion C1 and are locked to the upper end of the cylindrical portion C1. In addition, the camera unit 3 can rotate relative to the support member 4 around the central axis of the cylindrical portion C1. Such a rotation operation can be performed manually by a user or an operator, or mechanically by a predetermined button operation.

[0080] The cylindrical portion C1 of the housing 3b is provided with recessed portions (not shown) that are recessed radially outward at multiple locations in the circumferential direction. On the other hand, the support member 4 is provided with convex portions (not shown) having a shape corresponding to the above-mentioned concave portions between the multiple claw portions 4b. In addition, during the process of rotating the camera unit 3, the convex portions and the concave portions are engaged in a predetermined manner. That is, the configuration of the camera unit 3 (device) can be moved from one of the "first configuration" and the "second configuration" to the other by the rotation mechanism R1 including the cylindrical portion C1 and the claw portions 4b.

[0081] Here, the "first arrangement" refers to an arrangement in which a portion of the camera unit 3 (device) is present outside the housing 1 in a plan view (see Fig. 9C ). In normal use for shooting, such as Fig. 9B As shown, the camera unit 3 is in the “first arrangement.” In the “first arrangement,” the lens 31 a and the light emitting unit 3 e of the camera unit 3 are located on the front side of the housing 1 .

[0082] On the other hand, the "second arrangement" refers to an arrangement in which the entire camera unit 3 (device) overlaps with the housing 1 in a plan view (see Fig.9D ). In the "second configuration", the front end of the camera unit 3 does not protrude from the housing 1 to the front side, thereby preventing the camera unit 3 from contacting a person or an object during transportation of the refrigerator 100. In the first embodiment, the position of the camera unit 3 rotated 90° clockwise from the "first configuration" when viewed from above is set as the "second configuration". In this way, the camera unit 3 can move relative to the housing 1.

[0083] In addition to the above-mentioned structures, the refrigerator 100 also has Fig. 9B The radio wave cancellation suppression component 9 shown. The radio wave cancellation suppression component 9 is a component for suppressing mutual cancellation of radio waves, and is provided inside the support component 4. Generally, radio waves have the property of being reflected on the surface of metal components. Assuming that in a structure without the radio wave cancellation suppression component 9, when the radio wave from the antenna 3h is incident on the metal outer box 11 at an incident angle of 90°, the radio wave reflected on the surface of the outer box 11 returns to the antenna 3h at a reflection angle of 90°, so there is a possibility that mutual cancellation of radio waves will occur.

[0084] exist Fig. 9BIn the "first configuration" shown, a straight line (not shown) perpendicular to the upper surface of the frame 1 (the surface on which the camera unit 3 is installed) does not pass through the antenna 3h, so even in the absence of the radio wave cancellation suppression component 9, there is almost no mutual cancellation of radio waves. That is, in the "first configuration", there is no antenna 3h in the area where the upper surface of the frame 1 is projected upward, so there is almost no mutual cancellation of radio waves. It should be noted that the expression "installation surface" of the camera unit 3 is not limited to the case where the camera unit 3 is directly installed on the frame 1, but also includes the case where the camera unit 3 is installed on the frame 1. Fig. 9B The case where the camera unit 3 is installed via the support member 4 in this way.

[0085] On the other hand, in the "second configuration" (refer to Fig.9D ), the entire camera unit 3 overlaps with the frame 1 when viewed from above, so a straight line perpendicular to the upper surface of the frame 1 (the surface on which the camera unit 3 is installed) passes through the antenna 3h. That is, in the "second configuration", the antenna 3h exists in the area where the upper surface of the frame 1 is projected upward, so if there is no radio wave cancellation suppression component 9, there is a possibility that radio waves will cancel each other. Therefore, in the first embodiment, in particular, in order to suppress the "second configuration" (refer to Fig.9D ) and a radio wave cancellation suppression component 9 is provided to cancel out the radio waves in the circuit.

[0086] As such a radio wave canceling and suppressing member 9, for example, a metal plate such as aluminum, iron, or a predetermined alloy may be used. Fig. 9B As shown, the plate surface of the radio wave canceling suppressing member 9 is inclined in a predetermined manner relative to the upper surface of the housing 1 (the installation surface of the camera unit 3). The inclination manner and inclination angle of the radio wave canceling suppressing member 9 will be described later.

[0087] Furthermore, since the housing 3b of the camera unit 3 and the storage body 4a of the support member 4 are made of resin, there is no possibility of adversely affecting the radio waves (radio waves being reflected on the surface). Fig. 9B In the example, a refrigerator door 211 is provided directly below the antenna 3h, but the refrigerator door 211 is a structure in which the resin exterior is filled with insulating materials such as foamed polyurethane, so there is no possibility of adverse effects on radio waves (radio waves are reflected on the surface).

[0088] Fig. 9C It is a plan view showing the camera unit 3 in the “first configuration” with the upper cover of the casing 3 b removed.

[0089] As described above, the camera control board 31 and the wireless communication board 32 are connected via the wiring K1. In addition, power is supplied to the camera control board 31 from the box via the power cable K2. It should be noted that the power cable K2 is connected via the above-mentioned rotation mechanism R1 (see Fig. 9B ) of hole H1 (refer to Fig. 9B ) and plug it in.

[0090] exist Fig. 9C In the example of , a wireless communication board 32 is provided on the inner surface of the side wall of the housing 3b. When the wireless communication board 32 is provided, a double-sided tape or an adhesive may be used. In addition, a claw (not shown) for locking the wireless communication board 32 may be provided on the housing 3b. By providing the wireless communication board 32 on the side wall of the housing 3b in this way, it is easy to ensure the installation space for other electronic parts. In addition, a radio wave cancellation suppression component 9 is provided at a predetermined position of the camera unit 3 that deviates from the "first configuration" when viewed from above.

[0091] Fig.9D It is a plan view showing the camera unit 3 in the “second configuration” with the upper cover of the casing removed.

[0092] It should be noted that in Fig.9D In the figure, the wiring K1 and the power cable K2 are omitted. Fig. 9C ) is rotated 90° clockwise to form the "second configuration" (refer to Fig.9D ), the camera unit 3 moves from the position of symbol Z1 to the position of symbol Z2. In such a "second arrangement", the radio wave cancellation suppressing component 9 and the wireless communication board 32 (ie, the antenna 3h) overlap when viewed from above.

[0093] Fig.9E It is used Fig.9D This is a schematic cross-sectional view of the camera unit 3 in the “second configuration” taken along line III-III.

[0094] like Fig.9E As shown, the housing 3b of the camera unit 3 includes a lower housing member 3D and an upper housing member 3U. The upper side of the lower housing member 3D is open. The lower side of the upper housing member 3U is open. The upper housing member 3U is provided so as to block the opening of the lower housing member 3D.

[0095] The storage body 4a of the support member 4 includes a lower base member 4D and an upper base member 4U. The upper side of the lower base member 4D is open. The lower side of the upper base member 4U is open. The upper base member 4U is provided so as to block the opening of the lower base member 4D.

[0096] like Fig.9EAs shown in FIG. 1 , in the “second configuration”, the radio wave canceling suppressing component 9 is disposed between the antenna 3h and the housing 1. Furthermore, a predetermined straight line L1 perpendicular to the upper surface of the housing 1 and passing through the antenna 3h passes through the radio wave canceling suppressing component 9. In short, in the “second configuration”, the radio wave canceling suppressing component 9 is disposed directly below the antenna 3h. If described from another point of view, the radio wave canceling suppressing component 9 is disposed between the lens 3a (refer to FIG. 1 ) of the camera unit 3. Figure 5 ) in the direction parallel to the optical axis (in Fig.9E In the example of the vertical direction), the antenna 3h is used as a reference and is away from the lens 3a (refer to Figure 5 ) is arranged on one side of the radio wave cancellation suppression component 9.

[0097] In addition, the plate surface of the radio wave cancellation suppression component 9 is inclined in a predetermined manner relative to the upper surface of the frame 1. Specifically, the plate-shaped radio wave cancellation suppression component 9 is inclined at about 45° relative to the upper surface of the frame 1. According to such a structure, among the radio waves radiated from the antenna 3h in all directions, the radio waves directed in the direction perpendicular to the upper surface of the frame 1 (that is, the direction directed vertically downward from the antenna 3h) are incident on the radio wave cancellation suppression component 9. As described above, since the radio wave cancellation suppression component 9 is inclined at about 45° relative to the surface of the frame 1, the incident angle of the radio wave (radio wave directed in the vertically downward direction) relative to the radio wave cancellation suppression component 9 is about 45°. In addition, the reflection angle when the radio wave is reflected by the radio wave cancellation suppression component 9 is also about 45°. As a result, the radio wave directed in the direction perpendicular to the upper surface of the frame 1 is reflected in a direction different from the antenna 3h, so that the mutual cancellation of radio waves can be suppressed.

[0098] In this way, the radio wave cancellation suppression component 9 has a function of reflecting the radio wave from the antenna 3h toward the radio wave cancellation suppression component 9 in a direction different from the antenna 3h. It should be noted that the inclination angle and the inclination direction of the radio wave cancellation suppression component 9 can be appropriately changed. In the case of using a metal plate as the radio wave cancellation suppression component 9, the radio wave cancellation suppression component 9 can be arranged in a manner that does not lead out a straight line (not shown) that is perpendicular to the plate surface of the radio wave cancellation suppression component 9 and passes through the antenna 3h. In this way, the radio wave reflected by the radio wave cancellation suppression component 9 can be prevented from returning to the antenna 3h.

[0099] Even when the camera unit 3 is in the "second configuration" (not shooting), wireless communication via the antenna 3h may be performed. Figure 6 ) and the user's portable terminal 54 (refer to Figure 6 ) when pairing is set between the portable terminal 54 and the server 53 (refer to Figure 6 ) provides the setting information of the refrigerator 100, wireless communication is performed via the antenna 3h. Next, use Figures 10A to 10EThe shape and the like of the radio wave canceling suppressing member 9 will be described in order.

[0100] Fig. 10A It is an explanatory diagram of a first example of the radio wave canceling suppressing member 9.

[0101] also, Fig. 10A The figure on the upper side of the paper is a top view of the radio wave canceling suppressing component 9 (a figure viewed from a direction perpendicular to the plate surface of the radio wave canceling suppressing component 9). Fig. 10A The figure on the lower side of the paper is a cross-sectional view of the radio wave canceling and suppressing component 9. Fig. 10A In the example, the plate surface of the metal radio wave canceling suppressing member 9 is flat. In the case of such a structure, as described above, the radio wave canceling suppressing member 9 can be made relative to the frame 1 (see Fig.9E ) is inclined in a predetermined manner. Thus, the radio waves reflected by the radio wave cancellation suppression component 9 can be directed toward the antenna 3h (refer to Fig.9E ) in different directions.

[0102] Fig. 10B It is an explanatory diagram of a second example of the radio wave canceling suppressing member 9A.

[0103] like Fig. 10B As shown, the metal radio wave canceling and suppressing component 9 can also be bent into a meandering shape in cross-section. In the case of such a structure, the radio wave canceling and suppressing component 9A can be relatively fixed to the frame 1 (see Fig.9E ) is tilted in a predetermined manner, or it may not be tilted in any particular manner. This is because, even when the radio wave canceling suppressing component 9A is not tilted in any particular manner relative to the upper surface of the frame 1, the radio wave is diffusely reflected and diffused on each of the sawtooth-shaped surfaces of the radio wave canceling suppressing component 9A, and its reflected wave is directed in a direction different from that of the antenna 3h. Without tilting the radio wave canceling suppressing component 9A in any particular manner relative to the upper surface of the frame 1 (or reducing the tilt angle), the height dimension of the radio wave canceling suppressing component 9A can be reduced, thereby increasing the degree of freedom in design.

[0104] Fig. 10C It is an explanatory diagram of a third example of the radio wave canceling suppressing member 9B.

[0105] like Fig. 10C As shown, the metal radio wave cancellation suppression component 9B can also be bent into a sawtooth shape when viewed in cross section. In such a structure, since the radio waves are diffusely reflected and diffused in the radio wave cancellation suppression component 9B, mutual cancellation of radio waves can also be suppressed. Fig. 10C In the example, there is no need to tilt the radio wave canceling and suppressing component 9B, so the height dimension can be reduced. As a result, the degree of freedom in design is improved. Fig. 10D , Fig. 10E The same is true in the example.

[0106] Fig. 10D It is an explanatory diagram of a fourth example of the radio wave canceling suppressing member 9C.

[0107] Fig. 10D The metal radio wave canceling suppressing member 9C shown is a structure in which a plurality of quadrangular pyramid-shaped components 9Ca are arranged in the vertical and horizontal directions. In such a structure, since radio waves are diffusely reflected and diffused in the radio wave canceling suppressing member 9C, mutual cancellation of radio waves can also be suppressed.

[0108] Fig. 10E It is an explanatory diagram of a fifth example of the radio wave canceling suppressing member 9D.

[0109] Fig. 10E The radio wave canceling and suppressing member 9D shown in the figure is in the shape of a rectangular plate and is Fig. 10A The same shape, but its constituent material is different from metal. That is, the radio wave canceling and suppressing component 9D is made of a rubber material that absorbs radio waves. Fig.9E ) At least a portion of the radio waves directed toward the radio wave cancellation suppression component 9D is absorbed by the radio wave cancellation suppression component 9D, thereby suppressing the mutual cancellation of radio waves. As such a rubber material, for example, a rubber material containing silicone rubber and magnetic particles can be used. In addition, the rubber material can also be formed into FIG. 10A to FIG. 10D The structure of the radio wave canceling and suppressing component 9D may also be a multilayer structure or a sandwich structure of different rubber material layers and different metal material layers. In the case of absorbing radio waves in this way, the plate surface of the radio wave canceling and suppressing component 9D may be relative to the frame 1 (refer to Fig.9E ) is parallel to the upper surface, and can also be inclined in a predetermined manner, which can be any one. It should be noted that, since various components for absorbing radio waves have been developed, they can also be appropriately used as the radio wave cancellation and suppression component 9D.

[0110] According to the first embodiment, by providing the radio wave cancellation suppression member 9 (see Fig.9E ), it is possible to suppress the mutual cancellation of radio waves radiated from the antenna 3h and the radio waves reflected from the surface of the frame 1. For example, even if the upper surface of the frame 1 is slightly bent due to the foaming pressure of the insulating material filled in the frame 1, and the vertical distance between the frame 1 and the antenna 3h becomes a multiple of 1 / 2 wavelength of the radio waves, the mutual cancellation of radio waves can be suppressed by the radio wave cancellation suppression component 9. In addition, even if the thickness of the camera unit 3 in the height direction is reduced at the design stage and the antenna 3h is set to be close to the upper surface of the frame 1, the mutual cancellation of radio waves can be appropriately suppressed.

[0111] In addition, according to the first embodiment, even when the camera unit 3 having the antenna 3h is independently designed and the wavelength of the radio wave can be selected, mutual cancellation of radio waves can be suppressed. Therefore, the reliability of wireless communication via the antenna 3h can be ensured. In addition, the radio wave cancellation suppression component 9 has a simple structure, so the increase in manufacturing cost can be suppressed.

[0112] Second Implementation Method

[0113] The second embodiment is different from the first embodiment in that the antenna 3h (see Fig.11A ) and the radio wave cancellation suppression component 9 (refer to Fig.11A ) are both provided in the camera unit 3A (refer to Fig.11A ). In addition, the wireless communication board 32 (see Fig.11A ) is different from the first embodiment in the front-to-back direction. It should be noted that the rest is the same as the first embodiment. Therefore, the parts different from the first embodiment are described, and the description of the repeated parts is omitted.

[0114] Fig.11A It is a cross-sectional view of a camera unit 3A included in the refrigerator according to the second embodiment.

[0115] It should be noted that in Fig.11A , the state where the lens 3a of the camera unit 3A is arranged on the front side of the frame 1, that is, the "first arrangement" is shown. Fig.11A As shown in FIG. 1 , an antenna 3h and a radio wave canceling and suppressing member 9 are provided inside the housing 3b of the camera unit 3A. Specifically, a wireless communication board 32 (also see FIG. 1 ) is attached to the side surface of the inner side of the housing 3b. Fig. 11B ). In addition, the radio wave canceling suppressing component 9 is provided on the bottom surface of the housing 3b of the camera unit 3A. The radio wave canceling suppressing component 9 may be Figures 10A to 10E Any structure in, but the following is the case where it is a metal plate (refer to Fig. 10A ) for explanation.

[0116] like Fig.11A As shown, in the "first configuration" in which the camera unit 3A can take pictures, the radio wave cancellation suppression member 9 is arranged between the antenna 3h and the housing 1. If described from another point of view, the radio wave cancellation suppression member 9 is arranged between the lens 3a (see FIG. 1 ) of the camera unit 3. Figure 5 ) of the optical axis (at Fig.11A In the example, the vertical direction is parallel to the antenna 3h, and the radio wave cancellation suppression component 9 is arranged on the side away from the lens 3a. Fig.11AIn the example, the straight line L2 perpendicular to the upper surface of the frame 1 passes through the antenna 3h, but since the radio wave cancellation suppression component 9 is interposed between the antenna 3h and the frame 1, there is almost no mutual cancellation of radio waves. It should be noted that the details of the configuration of the radio wave cancellation suppression component 9 will be introduced below.

[0117] Fig. 11B It is a plan view showing the state in which the upper cover of the casing 3b is removed in the "first configuration" of the camera unit 3A.

[0118] As described above, the wireless communication board 32 is attached to the inner side surface of the housing 3b. The wireless communication board 32 overlaps the radio wave canceling suppressing member 9 in a plan view. The radio wave canceling suppressing member 9 is provided below the wireless communication board 32 in a state inclined in a predetermined manner.

[0119] Fig. 11C It is used Fig. 11B This is a schematic cross-sectional view of the camera unit 3A in the “first configuration”, taken along line IV-IV.

[0120] As described above, a radio wave cancellation suppression component 9 is disposed between the antenna 3h and the frame 1. In addition, a straight line L2 perpendicular to the upper surface of the frame 1 and passing through the antenna 3h passes through the radio wave cancellation suppression component 9. Furthermore, the radio wave cancellation suppression component 9 is inclined in a predetermined manner relative to the upper surface of the frame 1. Specifically, the radio wave cancellation suppression component 9 is inclined at about 45° relative to the upper surface of the frame 1. According to such a structure, radio waves directed in a direction perpendicular to the upper surface of the frame 1 are reflected in a direction different from the antenna 3h, thereby suppressing mutual cancellation of radio waves. It should be noted that the inclination angle and inclination direction of the radio wave cancellation suppression component 9 can be appropriately changed.

[0121] According to the second embodiment, since both the antenna 3h and the radio wave canceling suppressing member 9 are provided inside the housing 3b of the camera unit 3A, Fig. 11C In the case of the "first configuration" shown in the figure, or in the case of the "second configuration" (not shown) in which the entire camera unit 3 overlaps with the frame 1 in a plan view, the relative positional relationship between the antenna 3h and the radio wave canceling suppressing member 9 can be maintained. Fig. 11C The same is true for the case of the "first arrangement" shown, and also in the case of the "second arrangement", it is possible to suppress the mutual cancellation of radio waves.

[0122] In addition, according to the second embodiment, in the "first configuration" (refer to Fig.11A ) in the vertical direction L2 (see Fig.11A) Even when the antenna 3h is passed, the mutual cancellation of radio waves can be suppressed. Therefore, the degree of freedom when the antenna 3h is set inside the housing 3b of the camera unit 3A is improved.

[0123] 《First Reference Method》

[0124] The first reference mode is different from the first embodiment in that no radio wave cancellation suppression component is specially provided. In addition, the first reference mode is different from the first embodiment in that the camera unit 3B (refer to Fig.12 ), the wireless communication function is switched to the off state. It should be noted that the other parts are the same as the first embodiment. Therefore, the parts different from the first embodiment are described, and the description of the repeated parts is omitted.

[0125] Fig.12 1 is a cross-sectional view of a camera unit 3B of a refrigerator including the first reference embodiment.

[0126] like Fig.12 As shown, a camera control board 31 and a wireless communication board 32 are provided inside the housing 3b of the camera unit 3B. However, no radio wave cancellation suppression component is particularly provided on the camera unit 3 and the support member 4. It should be noted that in the "first configuration", a straight line (not shown) perpendicular to the upper surface of the frame 1 is set not to pass through the antenna 3h. In addition, in the "second configuration", a straight line perpendicular to the upper surface of the frame 1 is set to pass through the antenna 3h.

[0127] In such a structure, the control unit 8 (refer to Figure 6 ) In the "first configuration" (refer to Fig.12 ), wireless communication is performed via the antenna 3h. That is, in the "first configuration" of the camera unit 3 (device), the wireless communication function using the antenna 3h is maintained in the on state.

[0128] In addition, the control unit 8 (see Figure 6 ) In the "second configuration" (not shown) in which the camera unit 3B is stored, wireless communication via the antenna 3h is not performed. That is, in the "second configuration" of the camera unit 3 (device), the wireless communication function remains in the off state. Thus, even in a structure where no radio wave cancellation suppression component is provided, mutual cancellation of radio waves can be prevented.

[0129] Second Reference Method

[0130] The second reference embodiment is different from the first embodiment in that the support member 4 (refer to Fig.13 ) and in the mounting member 10 (refer to Fig.13 ) is provided on the bottom surface of the wireless communication substrate 32 (refer to Fig.13 ). It should be noted that the rest is the same as the first embodiment. Therefore, the parts different from the first embodiment will be described, and the description of the overlapping parts will be omitted.

[0131] Fig.13 It is an explanatory diagram showing the arrangement of the mounting member 10 and the wireless communication board 32 of the refrigerator according to the second reference embodiment.

[0132] It should be noted that the mounting member 10 is disposed on the lower side of the supporting member 4, so it cannot be visually confirmed from the outside, but Fig.13 The supporting member 4 is shown by a two-dot chain line in the figure, and the mounting member 10 is shown in a perspective manner. The mounting member 10 is used to block the opening H3 on the upper surface of the outer box 11 and to connect the power cable K3 (see Fig.16 ) is a resin component inserted through the frame 1 and is arranged in the frame 1.

[0133] A rectangular opening H3 for installing the mounting member 10 is provided on the upper surface of the outer box 11 of the frame body 1. The mounting member 10 is formed with a fitting portion 10a that fits into the opening H3 of the outer box 11 and a guide portion 10b that extends backward from the fitting portion 10a. Fig.13 The wiring K1 shown by the dotted line is a wiring connecting the camera control board 31 and the wireless communication board 32, and is inserted through the hole H1 of the rotation mechanism R1. For example, in the case of using an antenna 3h with a printed circuit board (only copper foil printing) without components mounted, one wiring (coaxial cable) is used as the wiring K1. In addition, in the case of using an antenna 3h with a printed circuit board mounted with components, multiple wirings are used as the wiring K1.

[0134] Fig.14 It is a cross-sectional view of the camera unit 3 including a “second configuration” in addition to the wireless communication board 32 , the support member 4 , and the mounting member 10 .

[0135] like Fig.14 As shown, the mounting member 10 is L-shaped in longitudinal section, and is inserted from the inner side of the outer box 11 through the opening H3 on the upper surface of the outer box 11. That is, the mounting member 10 is inserted from the lower side of the upper surface of the outer box 11 through the opening H3 with the rear end of the guide portion 10b of the mounting member 10 facing upward, and then, most of the guide portion 10b is tilted backward in a state of being exposed on the upper side of the outer box 11, so that the guide portion 10b is in contact with the upper surface of the outer box 11. In addition, the fitting portion 10a is provided with a plate-shaped blocking portion 101a formed in a manner extending outward from its lower end. When the mounting member 10 is set in the outer box 11, the opening H3 of the outer box 11 is blocked by the blocking portion 101a.

[0136] It should be noted that the base member 4D (see Fig.15 ) is provided with an opening H4 for preventing interference with the mounting member 10 (see Fig.15 ). The mounting member 10 is provided through the opening H4. When the support member 4 is provided on the frame 1, the mounting member 10 is supported by the upper base member 4U (see Fig.16 ) covered status.

[0137] like Fig.14 As shown, when the mounting member 10 is installed in the outer box 11, the height position of the bottom surface of the fitting portion 10a is lower than the height position of the upper surface of the outer box 11 (i.e., the upper surface of the frame body 1). A hole for inserting the power cable K2 (see FIG. 1 ) is provided on the bottom surface of the fitting portion 10a. Fig.15 ) through hole H5 (refer to Fig.13 ). In addition, the fitting portion 10a includes an insertion portion 101b that bulges upward from the bottom surface thereof. The power cable K2 is inserted through the insertion portion 101b and guided to the guide portion 10b.

[0138] like Fig.14 As shown in the figure, a wireless communication board 32 is provided on the bottom surface of the fitting portion 10a. It should be noted that the wireless communication board 32 can be attached by double-sided tape or adhesive, and the wireless communication board 32 can also be fixed by a claw (not shown) of the fitting portion 10a. An antenna 3h is mounted on the wireless communication board 32. And, the image data captured by the camera unit 3, the setting information of the refrigerator 100, etc. are transmitted wirelessly via the antenna 3h.

[0139] As described above, the fitting portion 10a of the mounting member 10 is fitted into the opening H3 of the outer box 11. Therefore, the metal outer box 11 does not exist above or below the wireless communication board 32 provided on the bottom surface of the fitting portion 10a. Therefore, mutual cancellation of radio waves radiated from the antenna 3h does not occur.

[0140] Fig.15 It is a plan view including the camera unit 3 in a state where the upper casing member is removed and the support member 4 in a state where the upper base member is transparent.

[0141] Fig.15 The power cable K2 shown is a cable for supplying power supplied via a power plug (not shown) to the camera unit 3 and the like. Fig.15 2, but the number of power cables K2 can be changed as needed. The power cables K2 are sequentially passed through the insertion holes H5 (see FIG. Fig.13 ) and the hole H1 of the rotating mechanism R1 (refer to Fig.13) and is inserted into the interior of the camera unit 3. Such a power cable K2 is connected to the camera control board 31 (see Fig.13 )Electrical connection.

[0142] The mounting member 10 is provided with a connector N1 for electrical connection of the power cable K2. On the other hand, as described above, the wireless communication board 32 is provided on the bottom surface of the fitting portion 10a of the mounting member 10. That is, both the connector N1 and the wireless communication board 32 are provided on the mounting member 10. Thus, in the process of manufacturing the refrigerator 100 on the production line, the operator can simultaneously perform the operation of connecting the power cable K2 to the connector N1 and the operation of attaching the wireless communication board 32. Therefore, the manufacturing efficiency of the refrigerator 100 can be achieved.

[0143] Fig.16 This is a perspective view of a state in which the interior of the support member 4 is visually confirmed by opening 90 degrees with the rear end side of the upper base member 4U as a fulcrum.

[0144] It should be noted that in Fig.16 In the embodiment, the wireless communication substrate 32 is omitted (see Fig.15 )、Wiring K1 (refer to Fig.15 ) icon. Fig.16 The multiple fixing portions 61 shown fix the power cable K2 so that it can slide, and are provided on the inner surface of the upper base member 4U and also on the inner surface of the lower base member 4D. The power cable K2 is arranged in a meandering manner inside the support member 4 via the multiple fixing portions 61. By providing such a "play" on the power cable K2, the power cable K2 will not be disconnected even when the camera unit 3 is separated from the support member 4. In addition, when the camera unit 3 is separated, the sliding friction of the power cable K2 is dispersed to the multiple fixing portions 61, generating appropriate resistance.

[0145] It should be noted that the camera unit 3 does not need to be particularly firmly fixed to the support member 4. For example, when a force greater than a predetermined force is applied to lift the camera unit 3 from below, the camera unit 3 can be separated from the support member 4. Thus, when a person or an object comes into contact with the camera unit 3, a strong resistance between the camera unit 3 and the object can be suppressed.

[0146] In addition, the camera control board 31 (see Fig.15 ) and the wireless communication board 32 (refer to Fig.15 ) wiring K1 (refer to Fig.15) can be longer than the length of the power cable K2 from the connector N1. Thus, when the camera unit 3 is separated from the support member 4 while the wiring K1 and the power cable K2 are connected to the camera control substrate 31, the power cable K2 is stretched before the wiring K1 (i.e., when the wiring K1 is bent). Therefore, it is possible to prevent the wiring K1 from being broken. It should be noted that the power cable K2 is thicker than the wiring K1 and is in a winding state via a plurality of fixing portions 61, so it is unlikely to be broken.

[0147] 《Variation Example》

[0148] As mentioned above, although the refrigerator 100 etc. of this invention were demonstrated using each embodiment, it is not limited to these descriptions, and various changes are possible.

[0149] For example, in each embodiment, the camera unit 3 is described as being able to rotate relative to the support member 4, but the present invention is not limited thereto. That is, the camera unit 3 may be configured to be able to slide in the front-rear direction relative to the support member 4. In addition, the camera unit 3 may be configured to be foldable. In each of these structures, it is possible to move between a "first configuration" in which a portion of the camera unit 3 is present outside the frame 1 when viewed from above and a "second configuration" in which the entire camera unit 3 overlaps with the frame 1 when viewed from above.

[0150] In addition, in each embodiment, the camera unit 3 is described as being relatively movable with respect to the support member 4, but the present invention is not limited thereto. That is, the camera unit 3 may be fixed to the housing 1.

[0151] In addition, in each embodiment, the case where the antenna 3h of the wireless communication board 32 is entirely arranged to overlap the radio wave canceling suppressing component 9 in the direction perpendicular to the upper surface of the housing 1 is described, but the present invention is not limited thereto. That is, at least a portion of the antenna 3h may overlap the radio wave canceling suppressing component 9 in the direction perpendicular to the upper surface of the housing 1. Such a structure can also suppress the mutual cancellation of radio waves.

[0152] In each embodiment, the arrangement and angle of the wireless communication board 32 can be changed as appropriate. For example, the board surface of the wireless communication board 32 may be arranged parallel to the board surface of the camera control board 31.

[0153] In addition, in each embodiment, the case where the "device" provided by the refrigerator 100 is the camera unit 3 is described, but the present invention is not limited thereto. For example, the refrigerator 100 may also be provided with a "device" having a voice recognition function or a person recognition function based on a captured image as a "predetermined function" different from the cooling function and the wireless communication function. It should be noted that the installation surface of the above-mentioned "device" may be the upper surface of the frame 1, or may be a predetermined surface different from the upper surface of the frame 1.

[0154] In addition, each embodiment and each reference mode can be combined as appropriate. For example, the first embodiment and the second embodiment can be combined, and in a structure in which the camera unit 3 includes the antenna 3h and the radio wave cancellation suppression component 9 (refer to Fig.11A : Second embodiment), it is assumed that in the "first configuration" there is a refrigerator door 211 directly below the antenna 3h (refer to Fig. 9B : First implementation mode).

[0155] In addition, in the structure in which the antenna 3h is provided inside the housing 3b of the camera unit 3 (device) by combining the first embodiment and the first reference mode (first embodiment), the wireless communication function of the camera unit 3 can be maintained in the off state (first reference mode) in the "second configuration" in which the entire camera unit 3 overlaps with the frame 1 when viewed from above. In such a structure, mutual cancellation of radio waves can also be suppressed.

[0156] The refrigerator 100 and the like described in each embodiment and each reference form are merely examples, and each embodiment and the like can also be applied to other types of refrigerators.
