Description

Technical Field

[0001] This utility model relates to a door for household appliances. Background Technology

[0002] Household appliances such as cooking equipment, refrigerators, and laundry appliances, which house objects within their interior space and have doors, are widely used. These appliances may have a storage space inside a cabinet that forms the exterior, and a door for opening and closing the storage space.

[0003] In recent years, various electronic components have been installed inside the doors of household appliances. For example, lighting can be installed in the door to illuminate objects inside. Alternatively, a camera can be installed in the door to photograph objects. Such electronic components can illuminate or photograph objects inside the door through a viewing area formed in the door.

[0004] In this case, the door of the household appliance can be constructed from multiple stacked glass panels. Furthermore, the camera can be positioned between the multiple panels to reduce the influence of temperature and humidity inside the household appliance. Here, the panels can be formed from a transparent material such as glass.

[0005] However, if the camera is positioned between multiple panels, a ghosting phenomenon occurs, where objects outside the appliance are reflected between the multiple panels and captured by the camera. As mentioned above, if external objects are captured by the camera, they will overlap with objects inside the appliance, resulting in an inaccurate image being provided to the user.

[0006] In particular, when a user is in front of a home appliance, their image can be reflected onto the door panel and captured by a camera. This can lead to a violation of user privacy.

[0007] Furthermore, multiple glass panels can reflect light from external or internal lighting fixtures of the appliance. This reflected light is transmitted to the camera, potentially causing light leakage or glare in the captured image.

[0008] To address the aforementioned issues, the path of images of external objects to the camera can be cut off by reducing the transparent portion of the glass panel. However, this approach reduces the area where the user can directly observe the interior of the appliance, and the widened frame can negatively impact the door's aesthetics.

[0009] In addition, the surface of the glass panel of the door may be printed or deposited to give it a specific color. While this enhances the door's aesthetics, it reduces the light transmittance of the glass panel. Since the camera captures images of the interior space through the glass panel, this reduced light transmittance leads to a decrease in the quality of the images captured by the camera.

[0010] On the other hand, even if the camera is positioned between the glass panels that make up the door, the internal heat of the household appliance can be transferred into the door, posing a risk of damaging the camera. In particular, if the household appliance is a cooking appliance such as an oven, the risk of camera damage increases because the appliance transfers very high temperatures into the door whenever it is running.

[0011] Furthermore, if the temperature inside the door rises, the refractive index of light inside the door will change, causing distorted images to be transmitted to the camera. This reduces the accuracy of the images captured by the camera, resulting in a decline in the quality of household appliances. Utility Model Content

[0012] This invention addresses the problems of the prior art as described above. The purpose of this invention is to prevent reflected external light from being transmitted to the camera device by positioning the camera device outside the reflective area inside the door that reflects external light (visible light).

[0013] Another objective of this invention is to enable the camera device to capture clearer images by setting a shooting window independent of the door panel.

[0014] Another objective of this invention is to reduce the temperature of the camera device and its surrounding area by providing a cooling device around the camera device located inside the door.

[0015] According to the features of this utility model for achieving the objectives described above, the utility model may include: a door body disposed in front of a storage space for a household appliance; and a door panel attached to the door body. The door panel may include a plurality of panels. An interior door space may be configured, surrounded by the door body and the door panel. A camera assembly for acquiring images of the storage space may be disposed within the interior door space.

[0016] The plurality of panels may include: a front panel, forming the front of the door panel; and a rear panel, disposed rearwardly spaced from the front panel. Furthermore, the camera assembly may be disposed outside the area where the front panel and the rear panel face each other. As described above, since the camera device is located outside the path of light reflection between the panels, external light cannot reach the camera device. Therefore, the camera device can accurately capture images of only objects disposed inside the household appliance, and can achieve an effect of improved image quality.

[0017] The camera assembly can be positioned outside the transparent portion among the plurality of said panels.

[0018] Additionally, the camera assembly can be configured on the outer periphery of the rear panel.

[0019] Furthermore, the camera assembly can be separated from the surface of the front panel in the direction of the storage space.

[0020] In addition, the camera assembly can be configured separately from the front panel and the rear panel.

[0021] In addition, the door body may be provided with a shooting window that allows the storage space to be viewed in the direction of the camera assembly.

[0022] Additionally, a shooting window that allows the storage space to pass through can be provided on the outer periphery of the rear panel. The shooting window can be configured between the camera assembly and the storage space.

[0023] Furthermore, the shooting window can be formed by stacking multiple shooting panels on top of each other.

[0024] Additionally, the door body may be equipped with a cooling device that discharges air toward the camera assembly.

[0025] In addition, the cooling device can draw in air from the front of the door body and expel the drawn-in air toward the camera assembly.

[0026] Furthermore, based on a direction orthogonal to the direction separating the front panel and the back panel from each other, the peripheral portion of the front panel can extend further outward than the peripheral portion of the back panel, and a panel peripheral portion can be provided at the edge of the front panel. The light transmittance of the panel peripheral portion can be formed to be lower than that of the light transmittance of the light transmittance portion. The camera assembly can be disposed behind the panel peripheral portion.

[0027] Furthermore, a main body through-hole can extend through the door body, and a window assembly can be disposed in the main body through-hole. The window assembly may include: a window frame disposed in the main body through-hole; and a camera window that allows light from the storage space to pass through the camera assembly.

[0028] Additionally, the viewing window frame may include a mounting frame disposed in the main body through-section and having a first through-section at its center where the shooting window is disposed. The viewing window frame may include a pressure frame that is coupled to the mounting frame and has a second through-section at its center connected to the first through-section, and which applies pressure to the shooting window toward the main body through-section.

[0029] Furthermore, the viewing frame may be provided with an inclined portion formed at an angle toward the storage space. The camera assembly may be configured to tilt in the direction of the inclined portion.

[0030] Additionally, the camera assembly may include a mounting cover disposed on the door body. A cooling flow path for airflow can be formed between the mounting cover and the inclined portion.

[0031] Furthermore, the camera assembly can be fixed to the door body. The camera assembly can be disposed between the front panel and the rear panel.

[0032] Additionally, the camera assembly may include: a mounting cover fixed to the door body; and a camera unit disposed on the mounting cover and facing the storage space. In this case, at least a portion of the mounting cover may be disposed behind the periphery of the front panel.

[0033] Furthermore, a cooling section for external air to flow into can be formed in the door body. A cooling flow path connected to the cooling section can be formed between the camera assembly and the door body.

[0034] Additionally, the camera assembly may include a cooling device for circulating air. This cooling device can draw in air from outside the door body and discharge it towards the camera assembly.

[0035] Furthermore, the mounting cover may include a main cover portion fixed to the front frame and on which the camera unit is disposed. The mounting cover may also include a flow path cover portion joined to the main cover portion and forming a cooling flow path between the two portions. In this case, a cover penetration portion may be formed at the center of the main cover portion to draw in external air and transmit it towards the cooling flow path. One end of the cooling flow path may open toward the cover penetration portion, and the other end of the cooling flow path may open toward the camera unit.

[0036] Additionally, a cooling device may be provided in the through-hole of the cover to expel air toward the cooling flow path. One end of the cooling flow path may be open toward the cooling device, and the other end of the cooling flow path may be open toward the camera unit.

[0037] Furthermore, the main cover may include a main body fixed to the front frame and having the cover through portion formed at its center. The main cover may also include an extension body connected to the main body and extending along the storage space direction. In this case, the camera unit may be disposed on the extension body.

[0038] Additionally, the door body may be equipped with the camera assembly and a viewing window assembly that extends through the storage space. A cooling flow path may be formed between the camera assembly and the viewing window assembly. One end of the cooling flow path may be connected to the outside of the door body, and the other end of the cooling flow path may open toward the camera section of the camera assembly.

[0039] Furthermore, the cooling flow path can be formed in a downward inclined direction toward the camera section.

[0040] Additionally, the camera unit can be separated from the shooting window of the window assembly. The cooling flow path can be connected to the space between the camera unit and the shooting window.

[0041] Furthermore, a shooting space can be formed between the surface of the front panel, the edge of the rear panel, the window frame, and the mounting cover. The camera assembly can be configured within this shooting space.

[0042] Furthermore, the camera assembly and the window assembly can be configured at different heights relative to each other, based on a direction orthogonal to the direction that separates the front panel and the rear panel from each other.

[0043] Furthermore, a shooting space for configuring the camera assembly can be formed on the outer periphery of the rear panel. A barrier fence can be provided inside the door space to block the shooting space from the front panel.

[0044] Additionally, the shielding fence can be positioned between the lower part of the camera assembly and the upper part of the rear panel.

[0045] The household appliance door of this utility model, as described above, has the following effects.

[0046] In this invention, the camera device can be disposed inside a door, and at a position other than where the plurality of panels (glass, etc.) acting as reflectors face each other. As described above, since the camera device is located outside the path of light reflection between the panels, external light cannot reach the camera device. Therefore, the camera device can accurately capture images of only objects disposed inside the household appliance, and can achieve the effect of improving the image quality captured by the camera device.

[0047] In particular, because the camera device is located outside the path of light reflection between the door panels, it also prevents the image of the user located in front of the household appliances from being transmitted into the door and photographed by the camera device. Therefore, the door of this invention can also prevent the user's privacy from being violated by being photographed by the camera device.

[0048] Furthermore, in this invention, the camera device can be positioned on the outer periphery of the back panel of the door panel. Therefore, even if external light is reflected off the back panel, it will not reach the camera device. Additionally, since the outer periphery of the back panel is located closer to the storage space than the front panel of the door, it also has the advantage of creating conditions more conducive to capturing images of the storage space.

[0049] Furthermore, in this invention, the camera device can photograph the storage space without using the door panel, but rather through a separate shooting window. Therefore, even if the light transmittance of the door panel is reduced for the purpose of improving aesthetics or preventing reflections, the camera device can still obtain a clear image through the shooting window with higher light transmittance. Thus, image quality can be improved.

[0050] Furthermore, in this invention, the camera device can be installed on the door body instead of the door panel (glass, etc.). Since the camera device can be installed on the door body separately from the door panel, (i) the installation of the camera device is easier, (ii) when the door body is an injection-molded material with low thermal conductivity, the amount of heat transferred to the camera device can be reduced, and (iii) the risk of the camera device being exposed through the door panel can also be reduced.

[0051] Furthermore, in this invention, a cooling flow path can be formed around the camera device to allow external air to flow in and out. This cooling flow path can reduce the temperature of the camera device and improve its durability. In addition, when the temperature around the camera device drops, it can also prevent light from refracting due to the high temperature around the camera device, thus preventing distorted images from being captured.

[0052] Additionally, a cooling device, such as a cooling fan, can be added to the door. This cooling device can expel cool air from outside the door to the camera unit through a cooling flow path. This prevents the camera unit from overheating, thereby improving operational reliability.

[0053] In particular, since the camera device can be cooled, it can also be positioned closer to a storage space with higher temperatures. This increases the flexibility in camera installation and ensures a wide variety of shooting angles.

[0054] Furthermore, the cooling device can not only cool the camera unit but also other electronic components inside the door, and in particular, it can reduce the surface temperature of the door panel. This reduces the risk of burns when the user operates the door.

[0055] Furthermore, in this invention, if a mounting cover is provided on the door body, the camera device disposed on the mounting cover can also be installed inside the door. Therefore, the ease of installation of the camera device is improved, and since it is not necessary to fix the camera device to the door panel, the installation reliability of the camera device is also improved.

[0056] Furthermore, in this invention, if a mounting cover for fixing the camera device and a window assembly for fixing the shooting window (glass, etc.) are provided, a cooling flow path will naturally form between the mounting cover and the window assembly. Therefore, even if a separate cooling flow path is not formed inside the door, a cooling flow path surrounding the camera device can be ensured.

[0057] Furthermore, in this invention, since the camera device is positioned on the outer periphery of the rear panel, a bird's-eye view of the storage space from above can be ensured. This allows for capturing a wider area of ​​the storage space and also improves the quality of the captured images.

[0058] Furthermore, the camera device can be mounted at a suitable angle using the mounting housing. Therefore, a separate process for setting the shooting angle of the camera device can be omitted, resulting in high ease of installation.

[0059] Furthermore, in this invention, the camera device can be configured in a shooting space surrounded by a door panel, a window frame, and a mounting cover. This shooting space provides a cooling airflow path around the camera device and increases the freedom of the camera device's shooting angle.

[0060] Furthermore, in this invention, the shooting window can be composed of a plurality of panels. A plurality of panels can reduce the heat transferred to the camera device, thereby improving the durability of the camera device.

[0061] Furthermore, in this invention, a shielding fence can be installed inside the door in the direction that blocks the front panel and the camera device. If the shielding fence blocks the space between the front panel and the camera device, external light passing through the front panel will be blocked by the shielding fence and will not reach the camera device. This prevents external images from being captured by the camera device. Moreover, since the shielding fence is located on the reflection path of light towards the camera device, it is unnecessary to manufacture a large perimeter (frame portion) of the panel intended to prevent light reflection. Therefore, the opening width of the door can be increased, and the aesthetics of the door can be improved. Attached Figure Description

[0083] Hereinafter, some embodiments of the present invention will be described in detail with reference to the exemplary accompanying drawings. It should be noted that when assigning reference numerals to the constituent elements of the various drawings, the same reference numerals are assigned to the same constituent elements as much as possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, detailed descriptions of related well-known structures or functions are omitted when it is determined that a detailed explanation would hinder understanding of the embodiments of the present invention.

[0084] This utility model relates to a household appliance and a door for the household appliance (hereinafter referred to as "door 60"). Here, a household appliance can refer to one that has an internal storage space 41. The door 60 can be positioned in front of the storage space 41. Here, "in front" refers to the direction facing the user when the user is in front of the household appliance. (See reference...) Figure 1 The X-axis direction can be considered the front. The Y-axis direction can be considered the left-right width direction of the door 60. The Z-axis direction can be considered the vertical width direction, which is the height direction of the door 60. The following explanation will be based on these directions.

[0085] The aforementioned door 60 for household appliances can be applied not only to doors 60 of household appliances such as cooking equipment, refrigerators, freezers, kimchi refrigerators, plant cultivation devices, clothing care machines, washing machines, and dryers, but also to furniture doors or entrance doors. This utility model can be applied to a wide variety of household appliances with one or more doors 60. Cooking equipment may include ovens, microwave ovens, etc., which are enclosed cooking devices. The following description uses the application of the door 60 of this utility model to a cooking equipment as an example.

[0086] In this embodiment, electronic components can be configured inside the door 60. These electronic components can give the door 60 a variety of functions. For example, the electronic components may be electronic component unit 100 (see reference 100). Figure 2 In the case of [unclear], an image of the interior of the storage space 41 can be acquired through the electronic component unit 100. The door 60 can increase the illuminance inside the storage space 41. For this purpose, the electronic component unit 100 may be equipped with an image acquisition module 120 and a lighting device (not shown).

[0087] As another example, a display device (not shown) can also be configured as an electronic component in the door 60. The display device can provide the user with information about home appliances. The user can input operating commands through the display device.

[0088] The electronic component unit 100 or a portion of the display device may be disposed inside the door 60. In this case, the electronic components such as the electronic component unit 100 or the display device may receive and generate signals with the main control unit disposed on the main appliance body 10, or be connected to the main body 10 by wires for power supply. Hereinafter, the case where the electronic component disposed on the door 60 is the image acquisition module 120 will be described as an example.

[0089] Reference Figure 4 In this embodiment, the image acquisition module 120 may include a camera assembly 160 and a window assembly 130, described later. The camera assembly 160 may include a camera unit 170 for capturing images of the storage space 41. The window assembly 130 may be disposed between the camera unit 170 and the storage space 41, and may allow images of the storage space 41 to pass through the camera unit 170. Their detailed structures are described below.

[0090] Reference Figure 1 The front of the cooking appliance in this embodiment may include a door 60 and an operating section 15. Reference numeral 16 indicates a display section exposed on the front of the operating section 15. The image acquisition module 120 described above may be configured inside the door 60. The household appliance may also be a built-in household appliance. For example, the household appliance may be a cooking appliance installed in a built-in manner.

[0091] Reference Figure 2 The image acquisition module 120 captures images of the storage space 41 from an angle indicated by arrow ①. Additionally, in Figure 2 In the diagram, the direction in which external light travels into the interior of door 60 is indicated by arrow ②. Here, external light can refer to visible light reflected from external objects located outside the household appliance. The path of this visible light that passes through the front panel Ga of door 60 and is reflected inside door 60 is indicated by arrow ②.

[0092] As described above, in this embodiment, if external visible light enters the interior of the door 60, the visible light will be reflected inside the door 60, but the reflected visible light cannot reach the image acquisition module 120. This is because, in this embodiment, the image acquisition module 120 is disposed in the area Gs (refer to) where the door panels, acting as reflectors, face each other. Figure 8 The location is outside of ( ). More details will be provided later.

[0093] Reference Figure 3The figure shows the view of the door 60 from the rear. For reference, in the figure, reference numeral "I" indicates the inside of the door 60, that is, the direction of the storage space 41, and reference numeral "O" indicates the outside of the door 60, that is, the exterior of the household appliance. Figure 3 Based on this, the left side is equipped with storage space 41, and the right side corresponds to the exterior of the door 60.

[0094] The door 60 may be provided with a shooting window CW. The shooting window CW allows light to pass through to the camera assembly 160 of the image acquisition module 120. That is, the camera unit 170 of the camera assembly 160 can photograph the storage space 41 through the shooting window CW. In this embodiment, the shooting window CW is disposed on the outer periphery of the rear panel IP constituting the transmission section. Figure 3 Based on this, the shooting window CW is positioned above the edge of the second rear panel Gc. As described above, in this embodiment, the camera assembly 160 can shoot the storage space 41 through the separate shooting window CW, rather than through the second rear panel Gc.

[0095] As another example, the shooting view window (CW) can be omitted. If the shooting view window (CW) is omitted, the camera assembly 160 can shoot the storage space 41 through the rear panel IP. In this case, the shooting angle can be set with the camera assembly 160 facing the rear panel IP.

[0096] Reference Figure 3 and Figure 4 The components constituting this embodiment are described in detail. The door bodies 70, 80, and 90 that form the skeleton of the door 60 may include a plurality of frame components. In this embodiment, the door bodies 70, 80, and 90 may include a front frame 70, a rear frame 80, and an inner frame 90. They can be combined with each other to form a door body 70, 80, and 90. Here, 'front' refers to the front of the door 60 (as shown in the image). Figure 4 (The left side of the reference) is used as the reference.

[0097] A front frame 70 may be disposed in front of the door bodies 70, 80, and 90. More precisely, the front frame 70 may form the front skeleton of the door bodies 70, 80, and 90. The front frame 70 may be generally quadrilateral in shape. A front opening 72 may penetrate through the center of the front frame 70, exposing the door panel G. A front bracket 73 may protrude from the lower end of the front frame 70, and the front bracket 73 may be combined with the rear bracket (not shown) of the rear frame 80. Reference numeral 74 is a side cover, and the wiring harness (not shown) may be accommodated on the inner side of the side cover 74. Reference numeral 75 indicates a door handle for opening and closing the door 60.

[0098] On both sides of the front frame 70, the front panel Ga is in close contact with the back of the front frame 70. Figure 4 The diagram shows the front panel Ga in a state where it is in close contact with the back of the front frame 70. At this time, the perimeter of the front frame 70 is wider than the perimeter of the front panel Ga. Therefore, when the front panel Ga is in close contact with the back of the front frame 70, a mounting area (not given reference numerals) is formed on the back of the front frame 70 in the portion not covered by the front panel Ga. This mounting area can be formed on the surface of the front frame 70 outside the edge of the door panel G.

[0099] A mounting plate 71 may be configured in the mounting area. The mounting plate 71 may be configured on the back of the front frame 70, covering the portion not covered by the front panel Ga. The mounting plate 71 may be made of a different material than the main body of the front frame 70. For example, the front frame 70 may be made of metal, and the mounting plate 71 may be made of injection-molded resin. The mounting plate 71 may be configured with mounting covers 180 and 190 (described later), and may also have a front fastening portion 71a (see reference) for engagement with the rear frame 80 and the inner frame 90. Figure 6 ).

[0100] A cooling section 73 may be provided on the front frame 70. The cooling section 73 allows outside air to flow into the interior of the door 60 through the front frame 70. The cooling section 73 may be constructed to extend through the front frame 70. (See reference...) Figure 8 Cooling holes 73a may be formed in the cooling section 73, which can guide the flow of air in the front-rear direction (left-right direction based on the attached drawings) of the door 60. The external air flowing in in this way can be used for cooling the camera assembly 160 and the interior space of the door.

[0101] Reference Figure 10 Door hinges 78 may be provided on the door bodies 70, 80, and 90. Figure 10 The diagram shows the door hinge 78 positioned on the rear frame 80. A hinge arm 78a protrudes from the door hinge 78. This hinge arm 78a, as a part fixed to the main body of the household appliance, protrudes outward from the door 60.

[0102] Re-reference Figure 4A rear frame 80 can be attached to the front frame 70 via the door panel G. The rear frame 80 includes a generally rectangular rear frame body 81. When the door 60 is closed, the rear frame 80 can face the entrance of the opening of the storage space 41. A rear opening 82 can be opened at the center of the rear frame body 81. The rear opening 82 can have a structure that opens both front and rear, allowing the transparent portion V to see through the interior of the storage space 41. Reference numeral 88 indicates a cantilever through-hole for the hinge cantilever 78a to protrude.

[0103] The rear opening 82 of the rear frame 80 does not obstruct the transparent portion V. However, the rear frame 80 can obstruct the image acquisition module 120. Therefore, even when the door 60 is opened, most of the image acquisition module 120 will be obscured by the rear frame 80. Only the camera portion 170 constituting the image acquisition module 120 can be exposed through the rear through-hole 80H, which will be described later.

[0104] A cooling channel 85 may be formed in the rear frame 80. Air flowing into the door 60 through the cooling channel can be transferred to the main body 10 of the cooking appliance and perform a cooling function. Conversely, hot air from the main body 10 of the cooking appliance can flow into the cooling channel 85, pass through the interior of the door 60, and be discharged to the outside.

[0105] A rear through-hole 80H may be provided in the rear frame 80. The rear through-hole 80H may be formed to penetrate the rear frame 80. The rear through-hole 80H can be regarded as a shooting hole for the camera assembly 160 to take pictures of the interior of the storage space 41. The rear through-hole 80H may be connected to the inner through-hole 90H described below to form a continuous main through-hole 80H, 90H. The rear through-hole 80H and the inner through-hole 90H may be configured with the window frames 140, 150 described below. This structure will be described again later.

[0106] The inner frame 90 may be integrated with the rear frame 80. The inner frame 90 may be disposed between the rear frame 80 and the front frame 70. The rear panel IP may be disposed between the inner frame 90 and the rear frame 80. An insulator (not shown) may also be disposed between the inner frame 90 and the rear frame 80. If the inner frame 90 is integrated with the rear frame 80, the rear panel IP and the insulator can be secured.

[0107] In this embodiment, the inner frame 90 is composed of a first inner frame 91 and a second inner frame 95. A first inner opening 92 and a second inner opening 96 open at the center of the first inner frame 91 and the second inner frame 95, respectively. The first inner opening 92 and the second inner opening 96 connect to the rear opening 82, exposing the through-hole V. A hinge avoidance portion 93 is recessed on the side of the first inner frame 91. The hinge avoidance portion 93 may be recessed to avoid the portion where the door hinge 78 is mounted. As another example, the inner frame 90 may be omitted, or it may be formed by a portion of the rear frame 80.

[0108] An inner through-hole 90H may be provided in the inner frame 90. The inner through-hole 90H may be formed to penetrate the inner frame 90. The inner through-hole 90H can be regarded as a shooting hole for the camera assembly 160 to take pictures of the interior of the storage space 41. In this embodiment, the first inner through-hole 94 and the second inner through-hole 97 may be formed in the first inner frame 91 and the second inner frame 95, respectively. The first inner through-hole 94 and the second inner through-hole 97 may be connected to the rear through-hole 80H and form continuous main through-holes 80H and 90H. The rear through-hole 80H and the inner through-hole 90H may be configured with window frames 140 and 150 as described below.

[0109] An inner rib 92a may be provided on the back surface 91a of the first inner frame 91 along the edge of the first inner opening 92. The inner rib 92a protrudes towards the rear frame 80. The inner rib 92a can press against and secure the surface of the rear panel IP. (Refer to...) Figure 11 As can be seen, the inner rib 92a contacts the surface of the first back panel Gb in the back panel IP. The inner rib 92a can press the surface of the first back panel Gb towards the rear frame 80 and fix it without gap. The opposite surface of the back panel IP, that is, the surface of the second back panel Gc, can be supported by the rear rib 84c provided on the rear frame 80. As a result, the two side surfaces of the back panel IP can be supported by the rear rib 84c and the inner rib 92a, respectively.

[0110] The first back panel Gb and the second back panel Gc constituting the back panel IP can be separated from the front panel Ga. An airflow space can be formed between the back panel IP and the front panel Ga, which are separated in this way. Additionally, the back panel IP can form an insulated space within it to prevent internal heat from the storage space 41 from being transferred forward, i.e., to the door 60 side. Therefore, the back panel IP can also be considered a heat-insulating panel. As another example, the back panel IP can consist of only one panel, or it can consist of three or more panels. (Refer to...) Figure 8 A panel spacer G′ for maintaining the spacing may be configured between the first rear panel Gb and the second rear panel Gc.

[0111] Re-reference Figure 4 An image acquisition module 120 may be configured between the inner frame 90 and the front frame 70. The image acquisition module 120 may include the camera assembly 160 and the viewport assembly 130. The camera assembly 160 may be fixed to the front frame 70. The viewport assembly 130 may be fixed to the inner frame 90. A more detailed description of the structure will follow later.

[0112] Reference Figure 5 The cooling hole 73a is provided on the front frame 70. The cooling hole 73a may be formed at the upper center of the front frame 70. Alternatively, the cooling hole 73a may be formed on either side or the lower part of the front frame 70. The cooling hole 73a may correspond to the position of the image acquisition module 120 and may be formed in various locations. The transparent portion V is located at the center of the front frame 70, rather than at the cooling hole 73a.

[0113] Figure 6 The rear side of the assembly incorporating the front frame 70 and the front panel Ga is shown. As shown, the camera assembly 160 can be configured on the front frame 70. More specifically, the mounting covers 180, 190 of the camera assembly 160 and the camera section 170 can be fixed to the mounting plate 71 disposed on the upper part of the rear side of the front frame 70. The mounting covers 180, 190 are disposed on the mounting plate 71 and cover the cooling holes 73a. Thus, air flowing into the outside of the cooling holes 73a can flow along the mounting covers 180, 190. As another example, the mounting covers 180, 190 can also omit the mounting plate 71 and be directly fixed to the front frame 70.

[0114] If the mounting covers 180 and 190 are fixed to the mounting plate 71, a portion of the mounting covers 180 and 190 will protrude in the direction of the transmission portion V. More specifically, the main cover portion 180 constituting the mounting covers 180 and 190 is disposed on the mounting plate 71, and a portion of the main cover portion 180 extends in the direction of the transmission portion V. The camera portion 170 may be disposed in the portion extending in this way. The main cover portion 180 may be combined with the flow path cover portion 190, forming a cooling flow path between them. This structure will be described again later.

[0115] like Figure 6 As shown, the front panel Ga may have a panel perimeter PA surrounding the edge of the transparent portion V. The light transmittance of the panel perimeter PA is lower than that of the transparent portion V, thereby preventing the storage space 41 from being seen through. The panel perimeter PA may include: an upper perimeter PA1 surrounding the upper edge of the transparent portion V; a lower perimeter PA2 surrounding the lower edge of the transparent portion V; and a side perimeter PA3 surrounding both side edges of the transparent portion V. The upper perimeter PA1, lower perimeter PA2, and side perimeter PA3 are connected to each other and are approximately quadrilateral. In other words, the upper perimeter PA1 can be called the first perimeter, the lower perimeter PA2 can be called the second perimeter, and the side perimeter PA3 can be called the third perimeter.

[0116] The panel perimeter PA can prevent components disposed on the rear side of the front panel Ga from being exposed. For example, the panel perimeter PA can obscure the image acquisition module 120, which will be described later. In this embodiment, the image acquisition module 120 is disposed behind the upper perimeter PA1. For reference, Figure 8 The image acquisition module 120 is shown being obscured by the upper peripheral portion PA1. The panel peripheral portion PA not only obscures components but can also enhance the aesthetics of the door 60 by being printed with specific colors or shapes.

[0117] like Figure 7 The structure of the rear frame 80 is shown. A shooting window CW constituting the viewing window assembly 130 can be disposed in the rear through-hole 80H formed in the rear frame 80. The shooting window CW can protrude through the rear through-hole 80H toward the storage space 41. The camera unit 170 is disposed in front of the shooting window CW, so that the storage space 41 can be photographed through the shooting window CW.

[0118] Figure 8The interior of the door 60 is shown in cross-sectional view. As shown, the door 60 has an interior space surrounded by the door bodies 70, 80, and 90 and the door panel G. The interior space can be considered as being surrounded by the front panel G, the front frame 70, the rear frame 80, the inner frame 90, and the rear frame 80. The camera assembly 160 can be configured within the interior space of the door.

[0119] The camera assembly 160 can be configured outside the area where the front panel Ga and the rear panel IP face each other. Here, the area where the front panel Ga and the rear panel IP face each other refers to the space between the back of the front panel Ga and the front of the rear panel IP. Figure 8 In the accompanying drawings, reference numeral Gs denotes the area where the front panel Ga and the rear panel IP face each other (hereinafter referred to as the 'middle area'). In this embodiment, the periphery of the front panel Ga is wider than the periphery of the rear panel IP, so that the periphery of the front panel Ga does not face the rear panel IP, but faces the inner frame 90.

[0120] If the camera assembly 160 is located outside the central region Gs, external light will be reflected and unable to reach the camera assembly 160. Both the front panel Ga and the rear panel IP are reflective materials that readily reflect light, but if the camera assembly 160 is located outside the central region Gs, the reflected light will not reach the camera assembly 160. (Refer to...) Figure 8 A portion of the external light (arrow ①) is blocked by the periphery PA of the front panel Ga and cannot reach the camera assembly 160. A portion of the external light (arrow ②) passes through the transmissive portion V and is reflected by the rear panel IP, but the camera assembly 160, located outside the middle region Gs, is outside the reach of the reflected light. Therefore, the camera assembly 160 can accurately capture images of only the storage space 41 without simultaneously capturing images of external objects.

[0121] More specifically, based on a direction orthogonal to the direction spaced apart from the front panel Ga and the back panel IP, the periphery of the front panel Ga extends outward more than the periphery of the back panel IP, and a panel periphery PA is provided at the edge of the front panel Ga. In this case, the light transmittance of the panel periphery PA can be made lower than that of the transmissive portion. The image acquisition module 120 can be disposed behind the panel periphery PA, thereby being shielded from the front of the door 60. Figure 8 Based on this, the image acquisition module 120 is disposed behind the upper peripheral portion PA1 of the panel peripheral portion PA.

[0122] In this embodiment, the image acquisition module 120, including the camera assembly 160, is entirely disposed outside the central region Gs. More specifically, the image acquisition module 120 is disposed on the outer periphery of the rear panel IP. Here, the periphery of the rear panel IP refers to the edge of the rear panel IP, but... Figure 8 Based on this, it will become the upper end of the rear panel IP.

[0123] The image acquisition module 120 can be configured behind the perimeter PA of the front panel Ga. If the image acquisition module 120 is configured behind the perimeter PA, the perimeter PA prevents the image acquisition module 120 from being exposed to the front of the door 60. In this embodiment, the image acquisition module 120 is configured behind the upper perimeter. More specifically, based on the boundary L between the upper perimeter and the transparent portion V, the image acquisition module 120 can be configured outside the transparent portion V.

[0124] The camera assembly 160 can be spaced apart from the surface of the front panel Ga in the direction of the storage space 41. (Refer to...) Figure 8 The camera assembly 160 can be spaced rearward (to the right, based on the attached figures) from the back of the front panel Ga. If the camera assembly 160 is spaced from the surface of the front panel Ga in the direction of the storage space 41, then (i) it is possible to photograph the storage space 41 from a position closer to the storage space 41, (ii) it is possible to prevent the camera assembly 160 from being exposed to the outside through the front panel Ga, and (iii) it is possible to more reliably prevent light reflected from the back panel IP from reaching the camera assembly 160.

[0125] The camera assembly 160 can be configured separately from the front panel Ga and the rear panel IP. In this embodiment, the camera assembly 160 is separated from the surface of the front panel Ga by the storage space 41, and is also separated from the edge of the rear panel IP by the outer edge. This prevents heat from being directly transferred from the rear panel IP or the front panel Ga to the camera assembly 160.

[0126] The camera assembly 160 can be positioned closer to the shooting window CW than the surface of the front panel Ga. This allows for more accurate shooting from a position closer to the storage space 41. However, while the heat from the storage space 41 can be better transferred to the camera assembly 160, external air flowing in through the cooling hole 73a can effectively cool the camera assembly 160.

[0127] A shooting window (CW) that sees through the storage space 41 can be provided on the outer periphery of the rear panel IP. The shooting window CW can be positioned between the camera unit 170 and the storage space 41. Figure 8 As shown, the shooting window CW is positioned further outward than the upper edge of the rear panel IP. The camera unit 170 can capture images of the storage space 41 through the shooting window CW without passing through the rear panel IP. This allows the camera unit 170 to obtain clear images even when the light transmittance of the rear panel IP is reduced for aesthetic purposes or to prevent reflections, thanks to the higher light transmittance of the shooting window CW. Furthermore, since the camera unit 170 is positioned outside the door 60 and shoots at the storage space 41 in an angled direction, a wider shooting angle is ensured. Figure 8 The dashed line in the image represents the shooting range of the camera assembly 160.

[0128] Cooling devices CF that discharge air toward the camera unit 170 may be provided on the door bodies 70, 80, and 90. The cooling devices CF draw in external air and discharge it toward the camera unit 170. The cooling devices CF may be composed of axial flow fans. The cooling devices CF and the camera unit 170 may be controlled by a control unit (not shown).

[0129] The cooling device CF can be configured on the mounting covers 180 and 190. The cooling device CF can be configured on the mounting covers 180 and 190, and can be positioned corresponding to the cooling section 73. Thus, the cooling device CF can draw in external air through the cooling holes 73a. The structure of the cooling device CF will be described again later.

[0130] Figure 9 The path of airflow toward the camera unit 170 is shown. The cooling device CF can draw in external air through the cooling hole 73a (arrow ① direction). The air drawn in by the cooling device CF flows toward the camera unit 170 through the cooling flow path. More specifically, the drawn-in external air is first discharged into a first cooling flow path CP1 formed between the flow path housing 190 constituting the mounting housings 180, 190 and the cooling device CF. Then, the external air passes through a second cooling flow path CP2 (arrow ② direction) between the main housing 180 constituting the mounting housings 180, 190 and the viewing window frames 140, 150. Furthermore, the external air passes through a third cooling flow path CP3 formed between the lower part of the main housing 180 and the shooting window CW, during which the camera unit 170 can be cooled (arrow ③ direction).

[0131] On the other hand, external air can cool the camera unit 170 while flowing towards the shooting window CW. A portion of the air flowing into the shooting window CW can move towards the central region Gs and cool the surfaces of the front panel Ga and the rear panel IP respectively (arrow ④ direction). Another portion of the air flowing into the shooting window CW can also move towards the rear of the camera unit 170, that is, towards the substrate constituting the camera unit 170, and cool the rear of the camera unit 170 (arrow ⑤ direction). The cooling flow path will be explained again later.

[0132] Reference Figures 10 to 13 This describes the installation structure of the viewing window assembly 130. The viewing window assembly 130 can be configured between the camera assembly 160 and the storage space 41, allowing the camera unit 170 of the camera assembly 160 to photograph the storage space 41 through the viewing window assembly 130. The viewing window assembly 130 can also be assembled separately from the camera assembly 160 and then installed on the door bodies 70, 80, and 90.

[0133] The window assembly 130 can be configured on the main body through-holes 80H and 90H. The window assembly 130 configured on the main body through-holes 80H and 90H can transmit the image of the storage space 41 to the camera assembly 160 through the main body through-holes 80H and 90H. In this embodiment, the window assembly 130 is configured on the inner frame 90, and the camera assembly 160, including the mounting covers 180 and 190, is configured on the front frame 70.

[0134] As described above, the main body through-holes 80H and 90H include the inner through-hole 90H and the rear through-hole 80H. The window assembly 130 can be configured to pass through the inner through-hole 90H and be adjacent to the rear through-hole 80H. More specifically, a portion of the window frames 140 and 150 constituting the window assembly 130 can pass through the inner through-hole 90H and enter the rear through-hole 80H. The situation described above... Figure 11 As shown in the image.

[0135] The window assembly 130 may include window frames 140 and 150 disposed in the main body through portions 80H and 90H. The window frames 140 and 150 can be regarded as frames for fixing the shooting window CW. The window frames 140 and 150 can fix the position of the shooting window CW and can form a cooling flow path together with the camera assembly 160.

[0136] The viewing frames 140 and 150 can be formed in a generally rectangular shape. The viewing frames 140 and 150 are structures that surround the shooting window CW disposed at their center. With the viewing frames 140 and 150 fixed to the inner frame 90, the shooting window CW can be mounted on the viewing frames 140 and 150. As another example, the shooting window CW can also be first assembled onto the viewing frames 140 and 150, and then mounted onto the inner frame 90. As yet another example, the viewing frames 140 and 150 can also be integrally formed on the inner frame 90 or the rear frame 80.

[0137] The window frames 140 and 150 may include a mounting frame 140 and a pressure frame 150. For example... Figure 10 As shown, the mounting frame 140 and the pressure frame 150 may each have a corresponding first through-hole 142 and a second through-hole 152. The first through-hole 142 and the second through-hole 152 are connected to each other and frame through-hole 130H. The frame through-hole 130H can be connected to the main body through-holes 80H and 90H, so that the shooting window CW is exposed towards the storage space 41.

[0138] The mounting frame 140 is disposed on the main body through portions 80H and 90H, and a first through portion 142 is formed at its center. The first through portion 142 can be connected to the main body through portions 80H and 90H. The mounting frame 140 can keep the shooting window CW fixed to the inner frame 90. More specifically, the mounting frame 140 can temporarily fix the shooting window CW before it is combined with the pressure frame 150.

[0139] The pressure frame 150 can be combined with the mounting frame 140. A second through-hole 152 connected to the first through-hole 142 can be formed at the center of the pressure frame 150. The pressure frame 150 can apply pressure and support the shooting window CW in the directions of the main body through-hole 80H and 90H. That is, the shooting window CW, which is temporarily fixed to the mounting frame 140, is completely fixed by the pressure frame 150.

[0140] Reference Figure 11In this embodiment, since the first through-hole 142 is larger than the shooting window CW, the shooting window CW can pass through the first through-hole 142. However, since the shooting window CW is larger than the rear through-hole 80H of the main body through-holes 80H and 90H, the edge of the shooting window CW will be stuck at the edge of the rear through-hole 80H. With the mounting frame 140 mounted on the main body through-holes 80H and 90H, if the shooting window CW is positioned on the first through-hole 142, the lower end of the shooting window CW can be supported by the mounting lower part 142A of the mounting frame 140 corresponding to the lower edge of the first through-hole 142. The edge surface of the shooting window CW can be supported by the window support ends 84A and 84B provided at the edge of the rear through-hole 80H.

[0141] On the other hand, the shooting window CW is formed as a second through-hole 152 larger than the pressure frame 150. A pressure rib 157 protrudes from the edge of the second through-hole 152, and the pressure rib 157 is formed in a direction that narrows the width of the second through-hole 152. Therefore, if the pressure frame 150 is attached to the mounting frame 140 with the shooting window CW in between, the pressure rib 157 of the pressure frame 150 can elastically support the edge surface of the shooting window CW in the direction of the rear frame 80. Thus, the two side surfaces of the shooting window CW can be supported by the window support ends 84A and 84B of the rear panel IP and the pressure rib 157 of the pressure frame 150, respectively.

[0142] Figure 12 The diagram illustrates the assembly of the viewport assembly 130. As shown, the shooting viewport CW can be exposed through the frame penetration 130H formed by the mounting frame 140 and the pressure frame 150. The portion exposed in this way extends through the main body penetrations 80H and 90H into the storage space 41. Because the shooting viewport CW is made of a transparent material, light from the storage space 41 can pass through the main body penetrations 80H and 90H and the frame penetration 130H to reach the camera assembly 160. For reference, in Figure 12 In the state shown, although the shooting window CW can pass through the frame through-part 130H, the edges of the shooting window CW will be stuck on the window support ends 84A and 84B of the rear panel IP, so it can be fixed in the front and rear directions respectively.

[0143] Reference Figure 13The mounting frame 140 is generally rectangular in shape, surrounding a central first through-portion 142. The mounting frame 140 may include a lower mounting portion 142A, an upper mounting portion 142B, and a pair of mounting sides 142C. The first through-portion 142 is formed between the lower mounting portion 142A, the upper mounting portion 142B, and the pair of mounting sides 142C. Reference numeral 141 denotes the mounting body, which is the portion inserted into the through-portions 80H and 90H of the body.

[0144] At this time, the width of the first through-hole 142 gradually narrows towards the rear frame 80. In this way, the first through-hole 142 naturally becomes an inclined structure, which can serve as the shooting angle for the camera section 170. In this embodiment, the mounting upper part 142B is formed in a direction inclined downwards towards the storage space 41, and the overall width of the first through-hole 142 can gradually narrow.

[0145] The pressurizing frame 150, like the mounting frame 140, has a generally rectangular shape surrounding a second through-hole 152 at its center. The pressurizing frame 150 may include a lower pressurizing portion 152A, an upper pressurizing portion 152B, and a pair of pressurizing side portions 152C. The second through-hole 152 is formed between the lower pressurizing portion 152A, the upper pressurizing portion 152B, and the pair of pressurizing side portions 152C.

[0146] Pressure ribs 157 are provided in the lower pressure portion 152A, the upper pressure portion 152B, and the pair of pressure side portions 152C in a direction that narrows the second through portion 152. The pressure ribs 157 can press against the edge surface of the shooting window CW. More specifically, the pressure ribs 157 can press against the edge surface of the shooting window CW towards the window support ends 84A and 84B of the rear panel IP. Thus, the two side surfaces constituting the edge of the shooting window CW can be supported by the pressure ribs 157 and the window support ends 84A and 84B, respectively.

[0147] At this time, the mounting upper part 142B and the pressurizing upper part 152B can be structures that are tilted downward toward the shooting window CW. This tilted structure can be configured to face the first tilted portion 184 of the mounting cover 180, 190 of the camera assembly 160 described below and form a second cooling flow path CP2. That is, the tilted structure of the mounting upper part 142B and the pressurizing upper part 152B can serve as a guide surface for forming a cooling flow path.

[0148] The mounting frame 140 may be provided with a first connecting piece 145, and the pressure frame 150 may be provided with a second connecting piece 155 corresponding to the first connecting piece 145. The first connecting piece 145 and the second connecting piece 155 may be joined together in an overlapping manner. In this state, a fastener (not shown) may be tightened to pass through the first connecting piece 145 and the second connecting piece 155, or the first connecting piece 145 and the second connecting piece 155 may be joined together by welding.

[0149] Reference Figure 11 The first connecting piece 145 and the second connecting piece 155 can be engaged with the edge of the first inner through-hole 94 of the first inner frame 90 that constitutes the inner frame 90. Therefore, the window assembly 130 cannot further enter towards the rear frame 80, and the installation position of the window assembly 130 can be determined. The first connecting piece 145 and the second connecting piece 155 can also be secured to the edge of the first inner through-hole 94 by fasteners.

[0150] Then, refer to Figures 14 to 17 The structure of the camera assembly 160 is described below. The camera assembly 160 is provided with the mounting plate 71. The camera assembly 160 can be fixed to the mounting plate 71 to shield the cooling portion 73 formed on the mounting plate 71. Figure 14 The image shows the cooling section 73 being obscured by the camera assembly 160. As another example, the cooling section 73 is omitted, and the camera assembly 160 can be positioned at different locations on the mounting plate 71, independent of the cooling section 73.

[0151] The camera assembly 160 may include the camera unit 170 and mounting covers 180 and 190 for fixing the camera unit 170. The mounting covers 180 and 190 not only fix the camera unit 170 but also form a cooling flow path for transferring external air to the camera unit 170. Figure 14 Based on this, the upper part of the camera assembly 160 is for introducing external air and for fixing the camera assembly 160, and the lower part of the camera assembly 160 is for fixing the camera unit 170.

[0152] Reference Figure 15The mounting covers 180 and 190 may include a main cover portion 180 and a flow path cover portion 190. The main cover portion 180 may be fixed to the front frame 70. The camera portion 170 may be disposed on the main cover portion 180. The flow path cover portion 190 may be combined with the main cover portion 180. The flow path cover portion 190 may form a cooling flow path between itself and the main cover portion 180. The flow path cover portion 190 is a cover-like structure that covers the cooling device CF.

[0153] A cover penetration 181a is formed at the center of the main cover portion 180. The cover penetration 181a can be connected to the cooling section 73. Thus, external air can flow into the interior of the door 60 through the cover penetration 181a. The external air flowing in in this way can be transmitted in the direction of the cooling flow path. The main cover portion 180 may have a structure corresponding to the cooling section 73.

[0154] A cooling device CF may be disposed in the through-hole 181a of the housing. The cooling device CF may be a cooling fan. The cooling device CF is composed of an axial flow fan and can draw in air in the front-to-back direction. Although not shown, the cooling device CF may be controlled and powered by the control unit together with the camera unit 170. As another example, the cooling device CF may be omitted. Even without the cooling device CF, external air can still flow in through the cooling section 73.

[0155] A close examination of the structure of the main cover portion 180 reveals that it can be composed of a cover body 181 and an extension body 183. The cover body 181 is fixed to the front frame 70, more specifically, to the mounting plate 71, and has a cover through portion 181a formed at its center. The extension body 183 can be connected to the cover body 181 and extends along the direction of the storage space 41. The extension body 183 can extend from the cover body 181 in a downwardly inclined direction toward the storage space 41.

[0156] The camera unit 170 can be disposed on the extension body 183. Since the extension body 183 extends in an inclined direction, the camera unit 170 can also have an inclined angle. For example... Figure 15 and Figure 16 As shown, the extension body 183 may include a first inclined portion 184, a second inclined portion 185, and a connecting side portion 187. The first inclined portion 184, the second inclined portion 185, and the connecting side portion 187 may form a three-dimensional structure surrounding the camera portion 170. (Refer to...) Figure 16The camera unit 170 is housed in a mounting space 189 surrounded by the first tilting portion 184, the second tilting portion 185, and the connecting side portion 187.

[0157] The first inclined portion 184 is a flat plate structure extending downwardly from the main body 181 of the housing. The second inclined portion 185 can be provided from the first inclined portion 184 at a different angle than the first inclined portion 184. In this embodiment, the second inclined portion 185 is formed in a direction inclined downward toward the transparent portion. The camera portion 170 can be disposed on the second inclined portion 185. Reference numeral 186 indicates a shooting hole formed in the second inclined portion 185, and the lens 171 of the camera portion 170 can be located at the shooting hole 186. The connecting side portion 187 constitutes the two sides of the extension body 183.

[0158] The flow path cover portion 190 can be attached to the main cover portion 180. When the flow path cover portion 190 is attached to the main cover portion 180, the cooling device CF is shielded. The flow path cover portion 190 can direct the direction of airflow from the outside air drawn into the cooling device CF. More specifically, the flow path cover portion 190 can direct the drawn-in outside air towards the camera portion 170. The flow path cover portion 190 can form a continuous cooling flow path from the cooling device CF towards the camera portion 170.

[0159] Reference Figure 9 The flow path cover portion 190 and the cooling device CF can be spaced apart from each other, and a first cooling flow path CP1 is formed in the spaced-apart portion. A second cooling flow path CP2 connected to the first cooling flow path CP1 can be formed between the main cover portion 180 and the window frames 140, 150. More specifically, the second cooling flow path CP2 can be formed between the first inclined portion 184 of the main cover portion 180 and the inclined surfaces formed by the mounting upper portion 142B and the pressurizing upper portion 152B constituting the window frames 140, 150. A third cooling flow path CP3 connected to the second cooling flow path CP2 is formed between the shooting window CW and the second inclined portion 185.

[0160] As described above, in this embodiment, a cooling flow path toward the camera section 170 can be formed between the camera assembly 160 and the window assembly 130. A second cooling flow path CP2 is formed between the main housing section 180 constituting the camera assembly 160 and the window frames 140 and 150 constituting the window assembly 130.

[0161] Re-reference Figure 15The flow path cover 190 may include a first flow path body 191, a second flow path body 193, and a side body 194. The second flow path body 193 may be disposed on the upper part centered on the first flow path body 191. The second flow path body 193 may have a shape in which its width gradually narrows towards the upper end. The inclined structure of the second flow path body 193 can guide external air downwards. The side body 194 can prevent external air from leaking to both sides.

[0162] At this time, the lower end of the first flow path body 191 opens downward. The portion opened in this way can open toward the first inclined portion 184 of the main cover portion 180. Although the first inclined portion 184 is not covered by the flow path cover portion 190, it can be separated from the surfaces of the window frames 140, 150 constituting the window assembly 130 and form a second cooling flow path CP2 therebetween.

[0163] Figure 17 The diagram shows the case where the inner frame 90, rear frame 80, and window assembly 130 are omitted. Referring to this, the lower end of the first flow path body 191 can be seen to open downwards. This open portion faces the first inclined portion 184, which, as described above, faces the window frames 140 and 150 and forms the second cooling flow path CP2. The lower end of the first flow path body 191 can be configured adjacent to the mounting upper portion 142B and pressurizing upper portion 152B constituting the window frames 140 and 150, and the first cooling flow path CP1 can form a continuous path with the second cooling flow path CP2.

[0164] Reference Figure 15 and Figure 17 Reference numeral 73b indicates a first fixing part 73b disposed on the cooling section 73. The first fixing part 73b may be combined with a second fixing part 182b of the main cover section 180 and a third fixing part 192 of the flow path cover section 190. That is, if a fastener such as a screw (not shown) is fixed to the first fixing part 73b via the third fixing part 192 and the second fixing part 182b, the mounting covers 180 and 190 will be fixed to the mounting plate 71.

[0165] Figure 18The internal structure of a second embodiment of the door for household appliances of this utility model is shown. Only the parts that differ from the above embodiment will be described. The shooting window CW can be constructed by stacking a plurality of shooting panels CW1 and CW2 on top of each other. The plurality of shooting panels CW1 and CW2 constituting the shooting window CW can each be made of a transparent material, allowing light to pass through. For example, the shooting panels CW1 and CW2 can both be made of glass and can be stacked on top of each other in the front-to-back direction, allowing light to pass through. As described above, by providing a plurality of shooting panels CW1 and CW2, heat from the storage space 41 can be prevented from being transferred to the camera section 170.

[0166] Figure 19 The internal structure of a third embodiment of the door for household appliances of this utility model is shown. Only the parts that differ from the above embodiments will be described. A shielding fence 188 may be provided inside the door space to block the camera window CW and the front panel Ga. The shielding fence 188 can block the camera window CW, thereby preventing external light from passing through the front panel Ga and reaching the camera unit 170.

[0167] The shielding fence 188 can be disposed between the lower part of the camera assembly 160 and the upper part of the rear panel IP. More specifically, the upper end of the shielding fence 188 can face the lower part of the camera assembly 160, and the lower end of the shielding fence 188 can face the upper part of the rear panel. In this embodiment, the shielding fence 188 can protrude from the main housing portion 180 constituting the camera assembly 160. That is, the shielding fence 188 can be part of the main housing portion 180. More specifically, the shielding fence 188 can protrude downward from the lower end of the extension body 183 of the main housing portion 180, that is, from the edge of the rear panel IP.

[0168] The lower end of the shielding fence 188 may face toward and be spaced apart from the pressure frame 150 constituting the window assembly 130. Air can flow through the portion separated in this way. In this embodiment, the lower end of the shielding fence 188 may extend to a position spaced a predetermined distance from the bottom surface of the pressure frame 150 constituting the window assembly 130.

[0169] As described above, since the shielding fence 188 blocks the shooting window CW, it can prevent external light from passing through the front panel Ga and reaching the camera unit 170. Therefore, in this embodiment, the periphery PA of the panel can also be formed to be relatively short. (Refer to...) Figure 19 It can be seen that the upper peripheral portion PA1 is different from the above embodiment (refer to Figure 8It is formed in a shorter length. Even if the area of ​​the periphery PA of the panel is reduced, resulting in a wider area for external light to pass through, there is no need to worry about light reaching the camera section 170 because the shielding fence 188 can block the shooting window CW.

[0170] Figure 20 The internal structure of a fourth embodiment of the door for household appliances of this utility model is shown. Only the parts that differ from the above embodiments will be described. A shielding fence 158 may be provided inside the door space to block the camera window CW and the front panel Ga. The shielding fence 158 can block the camera window CW, thereby preventing external light from passing through the front panel Ga and reaching the camera unit 170.

[0171] The shielding barrier 158 can be disposed between the lower part of the camera assembly 160 and the upper part of the rear panel IP. More specifically, the upper end of the shielding barrier 158 can face the lower part of the camera assembly 160, and the lower end of the shielding barrier 158 can face the upper part of the rear panel. In this embodiment, the shielding barrier 158 can protrude from the pressure frame 150 constituting the window frames 140, 150. That is, the shielding barrier 158 can be part of the pressure frame 150.

[0172] The upper end of the shielding fence 158 may face toward and be spaced apart from the camera assembly 160. Air can flow through the portion separated in this way. In this embodiment, the upper end of the shielding fence 158 extends to the underside of the extension body 183 of the main cover portion 180 constituting the camera assembly 160.

[0173] Similar to the above embodiment, since the shielding fence 158 blocks the shooting window CW, thereby preventing external light from passing through the front panel Ga and reaching the camera unit 170, in this embodiment, the periphery PA of the panel can also be formed to be relatively short. (Refer to...) Figure 20 This shows that the upper peripheral portion PA1 is different from the above embodiment (refer to...). Figure 8 The area of ​​the panel perimeter PA is reduced, resulting in a wider area for external light to pass through. Since the shielding fence 158 blocks the shooting window CW, there is no need to worry about light reaching the camera section 170.

[0174] Reference Figure 21In the illustrated embodiment, an image acquisition module 120, including the camera assembly 160, can be configured between the front panel Ga and the rear panel Gb constituting door panels Ga and Gb. The transmissive portion V of the front panel Ga is formed relatively closer to the center of the front panel Ga than the panel periphery PA of the front panel Ga. The transmissive portion V can form a continuous light transmission path together with the rear panel Gb. Reference numeral L indicates the boundary between the transmissive portion V and the panel periphery PA.

[0175] At this time, the image acquisition module 120 is positioned outside the transmittance portion V between the plurality of panels Ga and Gb. For example... Figure 21 As shown, the image acquisition module 120 is positioned outside the transmittance portion V, with respect to the height direction (vertical direction based on the attached figure). While the image acquisition module 120 could also be positioned where the front panel Ga and the back panel Gb face each other in the front-back direction (left-right direction based on the attached figure), it is positioned outside the transmittance portion V. In other words, the image acquisition module 120 can be positioned outside the transmittance portion V and facing the panel periphery PA in the front-back direction (left-right direction based on the attached figure). As described above, the image acquisition module 120 can be positioned outside the transmittance portion V to be outside the path of external light reflection.
