Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. Background Technology

[0002] As consumers demand more from fresh food preservation, vacuum drawers are increasingly being equipped in refrigerators because they extend the shelf life of food by creating a vacuum environment and reducing moisture loss.

[0003] In related technologies, the dim lighting inside vacuum drawers makes it difficult for users to clearly identify food details; it also makes it difficult to install a camera inside the vacuum drawer to determine food details through images. Summary of the Invention

[0004] This application provides a refrigerator to improve the synergistic optimization of the imaging device and the illumination module inside the vacuum drawer, thereby improving the visualization effect and the clarity of the captured images.

[0005] This application provides a refrigerator, which includes:

[0006] The container is designed to form a storage room.

[0007] A door, connected to the housing, is used to open or close the storage compartment;

[0008] A vacuum drawer is disposed within the storage compartment; the vacuum drawer includes:

[0009] The drawer shell is constructed to form a drawer cavity with an open front.

[0010] A drawer body is configured to form a storage cavity with an opening at the top; the drawer body is configured to be pull-outable from the drawer cavity through the opening; a drawer door is provided at the front end of the drawer body, and the drawer door is configured to form a light-transmitting area so that the interior space of the storage cavity is visible through the light-transmitting area;

[0011] A pressure relief component is provided on the drawer door and located outside the light-transmitting area; the pressure relief component is used to open or close the pressure relief hole connecting the drawer cavity and the external space;

[0012] A camera is configured to capture an image of the interior of the storage compartment; the camera is mounted at the junction of the top wall and the rear wall of the drawer shell.

[0013] The illumination module is installed on the top wall of the shell and located on the front side of the shooting device;

[0014] The optical axis of the shooting device is tilted toward the drawer door relative to a direction perpendicular to the horizontal plane.

[0015] The refrigerator of this embodiment achieves a large, continuous light-transmitting area by constructing a light-transmitting area on the drawer door and placing a pressure-relieving component on the outside of the light-transmitting area. Furthermore, the vacuum drawer of this embodiment has a light-illuminating module on the drawer shell to provide light to the storage cavity and increase the light intensity inside the storage cavity. An imaging device is installed on the drawer shell of the vacuum drawer to capture images of the interior of the storage cavity. The light-illuminating module enhances the light intensity inside the storage cavity, providing supplementary lighting for the imaging device and helping to improve the clarity of the images captured by the imaging device.

[0016] This application embodiment, through the coordination of the installation position of the shooting device, the installation position of the illumination module, and the tilt angle of the optical axis of the shooting device, ensures the reliability of the installation of the shooting device and the illumination module, ensures sufficient light for the captured image, and ensures sufficient light for direct observation of the storage state inside the storage cavity through the light-transmitting area.

[0017] In summary, the refrigerator of this application embodiment has at least the following technical effects:

[0018] Firstly, the design optimizes the synergy between enhanced visualization and image clarity: by placing the pressure relief component outside the light-transmitting area, the obstruction of the viewing line by the pressure relief structure in traditional designs is avoided, allowing the drawer door to form a large, continuous light-transmitting area. Users can directly observe the interior of the storage compartment without pulling out the drawer, reducing the disruption of the vacuum environment caused by frequent pulling and lowering of the vacuum pump, thereby extending the device's lifespan and saving energy. Simultaneously, the lighting module is located at the front of the shooting device, providing supplemental lighting for the camera while avoiding obstruction of the light path to the light-transmitting area, ensuring clarity for both direct user observation and image capture.

[0019] Secondly, the systematic optimization of spatial layout and optical path design: the shooting device is installed at an angle at the connection between the top wall and the rear wall of the shell, with the optical axis tilted forward, so that its shooting range covers the rear wall and top wall of the storage cavity, reducing shooting blind spots and ensuring the comprehensiveness of the captured images.

[0020] Furthermore, the establishment of a foundation for intelligent management: sufficient light and clear images provide a high-quality data foundation for intelligent functions such as food type identification and freshness analysis. Users can remotely view the storage status of food in the storage compartment through the refrigerator door screen or mobile terminal, reducing the number of times the door is opened and maintaining stable temperature.

[0021] In some embodiments of this application, the drawer body has a center surface, which is perpendicular to the horizontal plane and the rear side surface of the box, respectively.

[0022] The optical axis of the imaging device is located on the center surface of the drawer body.

[0023] This configuration, with the optical axis arranged along the center surface of the drawer, avoids image distortion caused by viewing angle shifts, providing data support for more accurate food positioning. Furthermore, the centered placement of the imaging device in the width direction avoids interference with the drawer's pulling trajectory, ensuring consistent positioning of the imaging device during repeated drawer opening and closing.

[0024] In some embodiments of this application, two lighting modules are provided, and the two lighting modules are symmetrically arranged about the center line of the drawer shell; wherein, the center line of the drawer shell extends along the depth direction of the box body, and the drawer shell is symmetrical about the center line.

[0025] This embodiment of the application enhances the light intensity within the storage cavity by incorporating two lighting modules. The two modules are symmetrically positioned at their center along the width, ensuring even light coverage from both sides of the storage cavity and preventing shadows or uneven brightness caused by unilateral illumination. This symmetrical arrangement of the two lighting modules utilizes the mechanical symmetry of the shell's top wall to reduce stress concentration caused by unilateral loads, thus enhancing module stability under low-pressure environments.

[0026] In some embodiments of this application, there is a first gap between the rear end of the illumination module and the rear wall of the housing, the first gap being less than one-quarter of the depth dimension of the drawer cavity.

[0027] This arrangement places the lighting module close to the rear of the storage compartment, allowing the light to directly illuminate the rear wall and corners of the compartment. This helps eliminate dark areas at the rear and improves the consistency of brightness between the front and back when the user observes through the light-transmitting area.

[0028] In some embodiments of this application, the illumination module has a second gap between itself and the adjacent sidewall of the drawer housing, the second gap being less than one-third of the width dimension of the drawer cavity.

[0029] By defining a second interval, the lighting module is positioned close to the side wall of the housing but at an appropriate distance, preventing the light from being blocked by the side wall of the housing. At the same time, the coverage of the light on the side wall area of ​​the storage cavity is expanded, reducing blind spots in the shooting.

[0030] In some embodiments of this application, the angle between the optical axis of the imaging device and the horizontal plane is 30° to 60°.

[0031] With this setup, the shooting range of the camera can simultaneously cover the inner surface of the top wall and the inner surface of the rear wall of the shell, enabling more comprehensive imaging of the storage cavity, reducing blind spots, improving image quality and the reliability of food identification; and ensuring that high-quality and comprehensive images of the storage cavity can still be obtained even with a fixed shooting device and shooting position.

[0032] In some embodiments of this application, the main ray direction of the illumination module is parallel to the height direction of the housing.

[0033] In this way, the light is projected vertically downwards, avoiding direct light shining on the rear wall of the housing and causing reflections that interfere with the shooting device. It also avoids glare caused by light shining forward, which would affect the user's comfort when observing directly.

[0034] In some embodiments of this application, the main light beam direction of the illumination module is tilted forward relative to the height direction of the housing.

[0035] The light is tilted forward and downward, prioritizing coverage of the front of the storage compartment, enhancing the brightness for users to observe directly through the light-transmitting area, while also providing forward supplemental lighting for the shooting device and reducing the risk of reflections from the rear wall.

[0036] In some embodiments of this application, a first mounting hole is provided on the drawer shell;

[0037] The imaging device includes:

[0038] A first light-transmitting cover covers the first mounting hole and a first sealing component is provided between it and the drawer shell;

[0039] A camera housing engages with the drawer housing; a first receiving cavity is formed between the camera housing and the first light-transmitting cover; the camera housing and the first light-transmitting cover abut against each other in the area outside the first mounting hole to press the first light-transmitting cover tightly against the drawer housing;

[0040] The camera is located inside the first receiving cavity and is fixedly connected to the camera housing.

[0041] The imaging device of this application embodiment has a first mounting hole on an opaque drawer shell, providing a structural basis for the imaging device to capture light from the storage cavity to form an image. A first light-transmitting cover ensures light transmission while sealing the first mounting hole; and a first sealing component between the first light-transmitting cover and the drawer shell ensures the airtightness of the drawer cavity in a vacuum environment, preventing air leakage in low-pressure environments. A camera housing is snapped into the drawer shell, forming a first receiving cavity with the first light-transmitting cover to accommodate and install the camera, providing external protection for the camera. By utilizing the area where the camera housing and the first light-transmitting cover abut against each other outside the first mounting hole, the first light-transmitting cover is pressed tightly against the drawer shell, achieving fixation of the first light-transmitting cover relative to the drawer shell, simplifying assembly steps, improving assembly efficiency, and simultaneously ensuring that the optical path of the camera is unobstructed.

[0042] In some embodiments of this application, the drawer shell is constructed to form an inclined mounting wall, which intersects with the top wall and the rear wall of the shell respectively; the inclined mounting wall is provided with the first mounting hole; the first light-transmitting cover protrudes from the inner surface of the drawer cavity onto the inner surface of the inclined mounting wall.

[0043] The protruding first light-transmitting cover essentially pushes the camera's "viewing window" into the drawer cavity, bringing it closer to the storage space. This effectively reduces the obstruction of light from the camera's edge by the wall of the first mounting hole, thereby maximizing the use of the camera's physical field of view and resulting in a wider shooting range.

[0044] In some embodiments of this application, the inner surface of the first light-transmitting cover does not protrude beyond the inner surface of the mounting inclined wall, and the wall of the first mounting hole is provided with an inclined surface facing the inner end of the drawer cavity; along the direction from the outer end to the inner end of the first mounting hole, the inclined surface is inclined away from the optical axis of the camera.

[0045] The inclined surface design causes the inner end of the first mounting hole to tilt away from the optical axis of the camera, forming a "trumpet mouth" opening at the inner end of the first mounting hole. This actively avoids the light path and prevents the hole wall from blocking the light and affecting the shooting range.

[0046] In some embodiments of this application, the drawer body has a clearance notch on the rear wall of the drawer, the clearance notch extending downward from the top of the rear wall of the drawer; along the height direction of the drawer body, the clearance notch is opposite to the shooting device.

[0047] By setting a clearance notch on the back wall of the drawer, a "window" is opened for the camera to capture images of the rear of the storage cavity. This reduces the obstruction of the camera's light by the back wall of the drawer, allowing the camera to capture light from the rear of the storage cavity through the clearance notch. This enables visualization of the rear and bottom areas of the storage cavity, reduces blind spots, and helps expand the actual effective monitoring range of the camera. It also allows a single camera in a fixed position to obtain near-panoramic monitoring capabilities of the storage cavity.

[0048] In some embodiments of this application, the drawer door body includes:

[0049] An inner light-transmitting panel faces the storage cavity; a portion of the inner light-transmitting panel protrudes towards or away from the storage cavity, forming a protrusion; a door seal is provided on the edge of the inner light-transmitting panel, the door seal being used to seal the opening of the drawer shell;

[0050] A door frame is constructed to form a viewing window; the door frame is fixedly connected to the inner light-transmitting panel.

[0051] An outer light-transmitting panel is fixed to the outside of the door frame and covers the viewing window; the area of ​​the outer light-transmitting panel opposite to the viewing window forms the light-transmitting area;

[0052] A sealing element is installed between the door frame and the inner light-transmitting panel;

[0053] The inner light-transmitting panel is provided with a first hole in the area opposite to the bottom edge of the door frame; the first hole communicates with the drawer cavity.

[0054] The sealing element is provided with a second hole section, which communicates with the first hole section to form the pressure relief hole; the second hole section communicates with the external space of the drawer cavity;

[0055] The pressure relief element is configured to open or close the second orifice.

[0056] The drawer door body of this application embodiment improves the structural strength of the drawer door body by setting an inner light-transmitting plate and an outer light-transmitting plate, and setting a local area of ​​the inner light-transmitting plate as a protrusion, so as to withstand the pressure of the low-pressure storage environment of the vacuum drawer. A door frame is provided to provide installation positions for the inner and outer light-transmitting plates.

[0057] The double-layer light-transmitting panel makes the vacuum drawer transparent, allowing you to observe the storage conditions inside the drawer cavity through the light-transmitting area of ​​the drawer door without opening the drawer body. This improves the convenience of using the vacuum drawer and also helps reduce the refrigerator's energy consumption.

[0058] In some embodiments of this application, the vacuum drawer further includes a handle, which is movably connected to the door frame; the handle is located below the outer light-transmitting panel.

[0059] The pressure relief component is located on the side of the handle facing the door frame.

[0060] The pressure relief component is located on the side of the handle facing the door frame, so that the pressure relief component faces the pressure relief hole, which facilitates sealing and opening the pressure relief hole. Moreover, the pressure relief component is hidden behind the handle, which helps to improve the aesthetics of the drawer body. This gives the vacuum drawer a simple, complete, and non-redundant visual appearance, minimizing the interference of functional components on the overall appearance.

[0061] Furthermore, by using the handle to shield the pressure relief component, the handle can also become a protective component for the pressure relief component. This can effectively prevent external forces from directly acting on the pressure relief component during daily cleaning, moving items, or accidental collisions, greatly reducing the risk of damage and improving the reliability and lifespan of the product.

[0062] In some embodiments of this application, the top wall of the shell is provided with a second mounting hole;

[0063] The illumination module includes:

[0064] The second light-transmitting cover is located inside the drawer cavity and is engaged with the top wall of the shell.

[0065] A light-transmitting cover is located on the outside of the drawer cavity, and a second sealing component is provided between it and the top wall of the shell;

[0066] The lamp housing is snapped into the top wall of the housing, and a second receiving cavity is formed between the lamp housing and the light-transmitting cover plate; the lamp housing and the light-transmitting cover plate abut against each other in the area outside the second mounting hole, so as to press the light-transmitting cover plate tightly against the top wall of the housing.

[0067] The lamp panel is located inside the second receiving cavity and is fixedly connected to the lamp housing.

[0068] The lighting module of this application embodiment has a second mounting hole on the opaque top wall of the housing, providing a structural basis for light from the lighting module to enter the storage cavity. The second light-transmitting cover, while allowing light to pass through, also serves to decorate and protect the electrical components inside the lighting module. The second mounting hole is sealed by the light-transmitting cover plate; a second sealing component is provided between the light-transmitting cover plate and the top wall of the housing to ensure the airtightness of the drawer cavity in a vacuum environment and prevent air leakage in a low-pressure environment. The lamp housing is snapped into the top wall of the housing, and the lamp plate is installed between the lamp housing and the light-transmitting cover plate, using the lamp housing to provide external protection for the lamp plate. The lamp housing and the area of ​​the second light-transmitting cover outside the second mounting hole abut against each other, pressing the second light-transmitting cover tightly against the top wall of the housing. This design eliminates the need for additional fixing structures; the light-transmitting cover plate is fixed simultaneously with the lamp housing installation, simplifying the assembly process and improving assembly efficiency.

[0098] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0099] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0100] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0101] The vacuum drawer of the refrigerator uses a vacuum device to create a vacuum, which improves the food storage and preservation effect by utilizing the low-pressure environment inside the drawer.

[0102] A vacuum drawer includes a drawer shell and a drawer body. The drawer shell forms a drawer cavity with an open front end, and the drawer body is pull-out and disposed within the drawer cavity.

[0103] In related technologies, because a low-pressure environment is created inside a vacuum drawer, the drawer door at the front end of the drawer body is equipped with ribs to ensure structural strength. The food inside the drawer cannot be clearly seen through the drawer door; users can only see the stored food by pulling out the drawer. Pulling out the drawer disrupts the vacuum storage environment, requiring a re-vacuuming process after pushing it back in. This increases the number of vacuuming cycles, reducing the lifespan of the vacuum drawer and increasing the refrigerator's energy consumption.

[0104] Therefore, some vacuum drawers incorporate a partially transparent section on the drawer door to allow users to view the contents without pulling the drawer out. However, due to the pressure relief mechanism on the drawer door, the transparent area is small and discontinuous, making it difficult for users to clearly see the food inside the drawer.

[0105] Besides users directly observing the internal storage through the drawer doors, cameras can also be used to capture images of the drawer's interior. However, due to dim lighting or light reflections within the drawer, the cameras often fail to capture clear images. This not only prevents users from observing the drawer's internal storage through images but also hinders intelligent management systems that use images to identify food types and freshness.

[0106] In view of this, the vacuum drawer of this application provides a basis for setting a single, continuous, large-area light-transmitting area by placing the pressure relief component outside the light-transmitting area of ​​the drawer door. This single, continuous, large-area light-transmitting area provides a basis for clearly observing the storage conditions inside the drawer.

[0107] Through the coordinated layout of the shooting device and the lighting module, the lighting module can not only provide supplementary lighting for the shooting device, but also provide light for direct observation through the light-transmitting area.

[0108] In this way, users can not only directly observe the storage conditions inside the drawer through the light-transmitting area without depressurizing and opening the drawer, but also determine the storage conditions inside the drawer through images captured by the imaging device without opening the refrigerator door.

[0109] Furthermore, the images captured by the camera can provide data support for the intelligent management of ingredients inside the drawer.

[0110] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0111] First, it should be noted that in this embodiment, the width direction of the box corresponds to the specification appendix. Figure 1 The X-axis direction corresponds to the depth direction of the housing in Appendix 1 of the instruction manual, and the Y-axis direction corresponds to the height direction in Appendix 1 of the instruction manual. Figure 1 The Z-axis direction in the equation.

[0112] Combination Figure 1 This application provides a refrigerator, including a cabinet 10, which defines a storage compartment 11 with a front opening.

[0113] Multiple storage compartments 11 can be provided to expand storage space. Depending on the storage temperature of the storage compartments 11, the storage compartments 11 can include at least one refrigerated compartment and at least one frozen compartment. The internal temperature of the refrigerated compartment can be maintained between approximately 0°C and 5°C for storing items in refrigeration mode; the internal temperature of the frozen compartment can be maintained between approximately -30°C and 0°C for storing items in freezing mode.

[0114] The cabinet 10 may include a cabinet shell and a cabinet liner, the cabinet liner being constructed to form a storage compartment 11 with a front opening; the cabinet shell is connected to the outside of the cabinet liner to form the appearance of a refrigerator.

[0115] The cabinet 10 may include multiple cabinet liner, for example, two cabinet liner are provided, one of which is used to form a freezer compartment and the other is used to form a refrigerator compartment.

[0116] Continue to refer to Figure 1 The refrigerator in this embodiment may also include a door 20, which is connected to the cabinet 10 to open or close the front opening of the storage compartment 11.

[0117] The door 20 can be hinged to the cabinet 10, allowing the door 20 to rotate relative to the cabinet 10 to open or close the storage compartment 11. The door 20 can also be formed on the outside of the drawer and move as the drawer is pulled out.

[0118] The refrigerator also includes a refrigeration unit that provides cooling to the interior to maintain a low-temperature environment in each storage compartment 11. The refrigeration unit includes a compressor, condenser, evaporator, and throttling devices. The specific structure and connections of the refrigeration unit can be found in relevant technical documents on refrigeration components, and will not be elaborated upon here.

[0119] Continue to refer to Figure 1 The refrigerator in this embodiment may also include a vacuum drawer 30, which is disposed in the storage compartment 11.

[0120] The vacuum drawer 30 is disposed within the storage compartment 11, which serves as a refrigerator compartment. In some embodiments of this application, the vacuum drawer 30 may be installed at the bottom of the refrigerator compartment and supported on the bottom wall of the refrigerator compartment.

[0121] Reference Figure 2 and Figure 3 The vacuum drawer 30 in this embodiment may include a drawer shell 100, which is configured to form a drawer cavity 102 with a front opening 101.

[0122] For example, the drawer shell 100 is a rectangular shell structure with a regular shape, which is easy to form.

[0123] Continue to refer to Figure 2 and Figure 3 The drawer shell 100 may include a top wall 110, a bottom wall 140, a rear wall 120, and two side walls 130. The top wall 110 and the bottom wall 140 are opposite to each other along the height direction of the box body 10 and are spaced apart. The rear wall 120 is fixed to the rear end of the top wall 110 and the bottom wall 140, and the two side walls 130 are fixed to both sides of the top wall 110 and the bottom wall 140 along the width direction. Thus, the top wall 110, the bottom wall 140, the rear wall 120, and the two side walls 130 enclose a drawer cavity 102 with a front opening 101.

[0124] As the pressure-bearing outer shell of the vacuum drawer 30, the structural strength of the drawer shell 100 is crucial. For example... Figure 2 and Figure 3 As shown, the outer surface of the drawer shell 100 is provided with reinforcing ribs, which are arranged in a grid pattern to ensure the structural strength of the drawer shell 100.

[0125] The inner surface of the drawer shell 100 does not require reinforcing ribs, which facilitates the pulling out of the drawer body 200. The two shell sidewalls 130 are equipped with slide rails facing the inner surface of the drawer cavity 102. These slide rails cooperate with the drawer body 200 to support it and restrict its pulling out relative to the drawer shell 100.

[0126] To further improve the structural strength of the drawer shell 100, the top wall 110, bottom wall 140, rear wall 120, and the two side walls 130 are connected by transition walls 150. Specifically, the rear wall 120 is connected to the top wall 110, the rear wall 120 to the bottom wall 140, and the rear wall 120 to the side wall 130 by transition walls 150; the side wall 130 is connected to the top wall 110, and the side wall 130 is connected to the top wall 110 by transition walls 150.

[0127] The transition wall 150 can be arc-shaped so that an arc-shaped transition connection wall is formed between two adjacent side walls of the drawer shell 100, which avoids stress concentration and helps to improve structural strength.

[0128] Continue to refer to Figure 3 The vacuum drawer 30 in this embodiment may also include a drawer body 200, which is used to construct a storage cavity 201 with a top opening, and the storage cavity 201 is used to store food and other items.

[0129] The drawer body 200 is configured to be pull-out from the drawer cavity 102 via an opening 101. When the drawer body 200 is pushed into the drawer cavity 102 via the front opening 101 of the drawer shell 100, the drawer body 200 closes the drawer cavity 102. The drawer body 200 is then pulled out from the drawer cavity 102 via the front opening 101. At this time, items can be taken out or put in through the top opening of the drawer body 200.

[0130] In this embodiment, the drawer body 200 is pullable relative to the drawer shell 100 along the depth direction of the box 10, meaning the pull-out direction of the drawer body 200 is parallel to the depth direction of the box 10. In this embodiment, the direction orthogonal to both the depth direction (front-back direction) and the height direction of the box 10 is denoted as the width direction of the vacuum drawer 30, and the width directions of the drawer shell 100 and the drawer body 200 are consistent with the width direction of the vacuum drawer 30.

[0131] A drawer door 210 is provided at the front end of the drawer body 200, which forms the exterior appearance of the drawer body 200. When the drawer body 200 is not pulled out, the drawer body 200 is located inside the drawer cavity 102; the drawer door 210 is sealed against the circumferential edge of the front opening 101 of the drawer shell 100, thereby closing the drawer cavity 102.

[0132] Combination Figure 2 and Figure 3 The vacuum drawer 30 in this embodiment may further include a vacuum device 300. The vacuum device 300 is configured to evacuate the vacuum drawer 30. When the drawer body 200 is fully pushed into the drawer shell 100, the drawer cavity 102 is closed, and the vacuum device 300 evacuates the closed drawer cavity 102, reducing the pressure inside the drawer cavity 102 to achieve low-pressure preservation and storage of the food inside.

[0133] For example, the vacuum device 300 may include a vacuum pump and an air pipe. The vacuum pump is mounted on the outer surface of the rear wall 120 of the drawer shell 100 and is connected to the drawer shell 100 via the air pipe and communicates with the drawer cavity 102.

[0134] It should be noted that after the vacuum device 300 evacuates the vacuum drawer 30, the drawer cavity 102 is in a low-pressure state, forming a low-pressure storage environment. According to one embodiment of this application, at the end of the vacuuming stage, the pressure inside the drawer cavity 102 is lower than one standard atmosphere or between one standard atmosphere and absolute vacuum. Because the pressure inside the drawer cavity 102 is lower than one standard atmosphere, it is commonly referred to by those skilled in the art as a "vacuum chamber".

[0135] Reference Figure 3 The vacuum drawer 30 provided in this application embodiment may also include a pressure relief component 400, which is used to relieve pressure on the vacuum drawer 30 that has been evacuated, so as to facilitate the pull-out and opening of the drawer body 200.

[0136] like Figure 3 As shown, a pressure relief hole 220 is provided on the drawer door 210, which connects the external space of the vacuum drawer 30 and the drawer cavity 102. A pressure relief component 400 is provided on the drawer door 210 and is configured to open or close the pressure relief hole 220. Before the vacuum device 300 evacuates air to form a low-pressure storage environment, the pressure relief component 400 closes the pressure relief hole 220 to form a sealed space inside the vacuum drawer 30; then the vacuum device 300 extracts the gas inside the vacuum drawer 30 to form a low-pressure storage environment.

[0137] It should be noted that the internal space of the vacuum drawer 30 includes the storage cavity 201 inside the drawer body 200 and the space between the drawer body 200 and the drawer shell 100. That is, the internal space of the vacuum drawer 30 is the space inside the drawer cavity 102 excluding the space occupied by the drawer body 200.

[0138] When the drawer body 200 needs to be pulled out, the pressure relief component 400 opens the pressure relief hole 220, allowing the gas in the external space to enter the internal space of the vacuum drawer 30 through the pressure relief hole 220, reducing the pressure difference between the inside and outside of the vacuum drawer 30, so that the user can pull out the drawer body 200 smoothly.

[0139] Continue to refer to Figure 3 In this embodiment, the drawer door 210 is constructed to form a light-transmitting area 202, allowing the user to observe the storage status inside the storage cavity 201 through the light-transmitting area 202 without having to open the drawer body 200. This reduces the frequency of vacuuming the vacuum drawer 30, which not only extends the service life of the vacuum drawer 30 but also helps to reduce energy consumption.

[0140] The light-transmitting area 202 of the drawer door 210 is a continuous single area with a large area, which helps to increase the area through which the user can observe the storage status inside the storage cavity 201. It also helps to improve the clarity of the observation of the storage status inside the storage cavity 201, thereby improving the visualization effect of the vacuum drawer 30.

[0141] The pressure relief component 400 is located on the outer side of the light-transmitting area 202. For example, the pressure relief component 400 may be located below the light-transmitting area 202; or, for another example, the pressure relief component 400 may be located on the side of the light-transmitting area 202 along its width. This arrangement ensures that the pressure relief component 400 relieves pressure on the vacuum drawer 30, while also preventing the pressure relief component 400 from being located in the middle area of ​​the drawer door 210, which would cause discontinuity in the light-transmitting area 202 and affect the visualization effect.

[0142] Continue to refer to Figure 3 The vacuum drawer 30 in this embodiment may further include a handle 410, which extends along the width of the drawer door 210. The handle 410 is connected to the drawer door 210 to move the drawer body 200.

[0143] Combination Figure 4 and Figure 5 The handle 410 is located below the light-transmitting area 202. On the one hand, the arrangement of the handle 410 conforms to the user's operating habits. On the other hand, the handle 410 does not block the light-transmitting area 202, improving the convenience and clarity for the user to observe the interior of the storage cavity 201 through the light-transmitting area 202.

[0144] The pressure relief component 400 is installed on the side of the handle 410 facing the drawer door 210, so that the pressure relief component 400 is indirectly connected to the drawer door 210 through the handle 410. In this way, the pressure relief component 400 is moved by the handle 410, thereby causing the pressure relief component 400 to seal or open the pressure relief hole 220.

[0145] The handle 410 is movably connected to the drawer door 210, allowing the handle 410 to move relative to the drawer door 210, thereby driving the pressure relief component 400 to move relative to the drawer door 210 to seal or open the pressure relief hole 220.

[0146] In some embodiments of this application, the handle 410 is rotatably connected to the drawer door 210, allowing the handle 410 to rotate relative to the drawer body 200. This arrangement makes it easier for the handle 410 to move the pressure relief component 400, improving the convenience of pressure relief.

[0147] In some embodiments of this application, the handle 410 is configured to rotate outward relative to the drawer body 200 to cause the pressure relief element 400 to open the pressure relief hole 220. The direction of rotation of the handle 410 can be referenced... Figure 2 The direction is R. With this design, on the one hand, the handle 410 rotates relative to the drawer body 200 to allow the pressure relief component 400 to open the pressure relief hole 220; on the other hand, the change from the rotation direction of the handle 410 relative to the drawer body 200 to the forward pulling direction of the handle 410 is more in line with human operating habits, making the opening of the drawer body 200 smoother.

[0148] Reference Figure 2 and Figure 3 The vacuum drawer 30 in this embodiment further includes a locking component 700, which is connected to the handle 410 and configured to lock or unlock the drawer body 200 and the drawer shell 100. The locking component 700 is connected to the handle 410, and through the movement of the handle 410 relative to the drawer door 210, the pressure relief component 400 is depressurized, while the locking component 700 is simultaneously unlocked.

[0149] In some embodiments, the locking assembly 700 may include a first locking member and a second locking member 720, wherein the first locking member is fixed to the side wall 130 of the drawer shell 100; and the second locking member 720 is connected to the handle 410. The second locking member 720 cooperates with the first locking member to lock or unlock the drawer body 200 and the drawer shell 100.

[0150] In some embodiments, the second locking member 720 may be sheet-like, and the second locking member 720 is disposed parallel to the side of the housing 10. This helps to reduce the space occupied by the second locking member 720 in the width direction. (Refer to...) Figure 4 In the front view of the vacuum drawer 30, the second locking element 720 is hidden behind the drawer door 210, so that the second locking element 720 is not exposed on the front of the vacuum drawer 30. This gives the vacuum drawer 30 a simple, complete, and non-redundant visual appearance, minimizing the interference of functional components on the overall appearance.

[0151] The second locking member 720 may include a main body, which may be triangular in shape to ensure structural strength.

[0152] The second locking member 720 may further include a locking part, which is connected to the main body and is used to cooperate with the first locking member to lock the drawer body 200 and the drawer shell 100.

[0153] The second locking member 720 may further include a first connecting portion, which is connected to the main body portion. The first connecting portion is rotatably connected to the side of the drawer door.

[0154] The second locking member 720 may further include a second connecting portion, which is connected to the main body portion. The second connecting portion is fixedly connected to the end of the handle 410.

[0155] Reference Figure 3 In some embodiments of this application, the locking assembly 700 may further include a rotating shaft 730, which is fixedly connected to the second locking member 720. The rotating shaft 730 is fixedly connected to the first connecting portion. A shaft hole 2137 is provided on the side of the drawer door 210, and the rotating shaft 730 is rotatably installed within the shaft hole 2137. The shaft hole 2137 is located on the side frame 2134 of the door frame 213. A limit switch is provided between the rotating shaft 730 and the drawer door 210 to prevent the rotating shaft 730 from dislodging from the shaft hole 2137. Through the cooperation of the rotating shaft 730 and the shaft hole 2137, the handle 410 can rotate relative to the drawer door 210.

[0156] Continue to refer to Figure 3 The locking assembly 700 may also include a torsion spring 740, which is sleeved on the rotating shaft 730. The two torsion arms of the torsion spring 740 abut against the door frame 213 of the drawer door 210 and the second locking member 720, respectively, to reset the handle 410.

[0157] When the handle 410 rotates relative to the drawer door 210 and pulls the drawer body 200 outward, the torsion spring 740 deforms elastically; when the handle 410 loses its force, the torsion spring 740 restores its deformation, causing the handle 410 to return to its original position.

[0158] It should be noted that after the handle 410 is reset, by pushing the handle 410 backward, the second locking member 720 cooperates with the first locking member to lock the drawer body 200 and the drawer shell 100.

[0159] The following reference Figure 5 and Figure 6 This application describes in detail the specific structure and function of the drawer body 200 and drawer door 210 in the embodiments of this application.

[0160] Reference Figure 6 The drawer body 200 includes a drawer bottom wall 231, a drawer rear wall 232, and two drawer side walls 233. The two drawer side walls 233 and the drawer rear wall 232 are located on the upper surface of the drawer bottom wall 231. The drawer bottom wall 231 is connected to the two drawer side walls 233 on both sides along its width direction, and the rear end of the drawer bottom wall 231 is connected to the drawer rear wall 232, forming a shell structure with a front opening and a top opening.

[0161] Among them, the bottom wall 231, the back wall 232, and the two side walls 233 of the drawer are integrally formed, which helps to improve the structural strength of the drawer body 200.

[0162] The front sides of the two drawer sidewalls 233 and the drawer bottom wall 231 form a snap-fit ​​structure, which snaps into the drawer door 210, forming a storage cavity 201 with an opening on the top side. The peripheral edge of the drawer body 200 protrudes from the edge of the shell structure, facilitating the sealing of the drawer door 210 with the drawer shell 100.

[0163] In some embodiments, the drawer door 210 may include multiple layers of light-transmitting panels to improve the structural strength and stability of the drawer door 210 and reduce the possibility of deformation of the drawer door 210 in a low-pressure storage environment.

[0164] Of course, in some possible implementations, the drawer door 210 can be equipped with a single-layer light-transmitting panel. By setting the material and shape of the single-layer light-transmitting panel, it can meet the pressure requirements of a vacuum drawer. This simplifies the structure of the drawer door 210.

[0165] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the drawer door 210 may include an inner light-transmitting panel 211, which faces the storage cavity 201. The snap-fit ​​structure formed by the two drawer side walls 233 and the front side of the drawer bottom wall 231 snaps into the inner light-transmitting panel 211, thereby achieving a fixed connection between the inner light-transmitting panel 211 and the shell structure.

[0166] The inner light-transmitting panel 211 can be a light-transmitting plastic sheet with high impact resistance and better pressure resistance. The inner light-transmitting panel 211 uses a high-transmittance plastic pressure-resistant sheet, ensuring both pressure resistance and high light transmittance. For example, the light transmittance of the inner light-transmitting panel 211 can be greater than 90%.

[0167] A portion of the inner light-transmitting plate 211 protrudes towards or away from the storage cavity 201, forming a protrusion 2111. The protrusion 2111 can be arc-shaped, with a simple shape that is easy to mold. For example... Figure 5As shown, a portion of the inner light-transmitting plate 211 protrudes away from the storage cavity 201 to form a protrusion 2111. With this arrangement, the surface of the inner light-transmitting plate 211 facing the storage cavity 201 has a recessed structure, which does not occupy the volume of the storage cavity 201 and can also increase the volume of the storage cavity 201.

[0168] The drawer door 210 of this embodiment improves the bending resistance of the inner light-transmitting plate 211 by providing an inner light-transmitting plate 211, and by forming a protrusion 2111 in a partial protrusion of the inner light-transmitting plate 211. This also allows the inner light-transmitting plate 211 to form a three-dimensional curved surface, which helps improve the rigidity of the inner light-transmitting plate 211. The protrusion 2111 helps to disperse stress and reduce the possibility of deformation. Therefore, the provision of the protrusion 2111 helps to enhance the pressure resistance of the inner light-transmitting plate 211 and reduces the possibility of deformation under pressure.

[0169] exist Figure 5 In the illustrated embodiment, a portion of the inner light-transmitting plate 211 protrudes outward from the storage cavity 201, forming a protrusion 2111. This creates an effect similar to a meniscus or wide-angle lens, expanding the user's field of vision to view the inside of the storage cavity 201. The user can capture images of a wider area within the storage cavity 201 without having to move their head at large angles or over a wide range, producing a sense of "unobstructed" transparency and helping to improve the overall comprehensiveness of observing the interior of the storage cavity 201.

[0170] Moreover, the outward-protruding protrusion 2111 forms a curved surface relative to the plane, which helps to reduce reflected glare and further helps to improve the clarity of observation.

[0171] A door seal 212 is provided on the edge of the inner light-transmitting panel 211, which is used to seal the opening 101 of the drawer shell 100. The door seal 212 is annular and located on the side of the inner light-transmitting panel 211 facing the storage cavity 201. The door seal 212 abuts against the front end face of the drawer shell 100, thereby sealing the drawer cavity 102.

[0172] The pressure relief hole 220 is located inside the annular door seal 212 to relieve pressure on the vacuum drawer 30.

[0173] In some examples, the inner light-transmitting plate 211 is provided with an annular groove on the side facing the storage cavity 201, a portion of the door seal 212 is interference-fitted with the annular groove, and / or a portion of the door seal 212 is bonded to the annular groove, thereby achieving a mechanical fixed connection between the door seal 212 and the inner light-transmitting plate 211 while ensuring the sealing between the door seal 212 and the inner light-transmitting plate 211.

[0174] Continue to refer to Figure 5 and Figure 6The drawer door 210 may also include a door frame 213, which forms a viewing window 2131. For example, the viewing window 2131 is rectangular, which not only facilitates processing but also helps to form a larger light-transmitting area 202.

[0175] The door frame 213 is fixedly connected to the inner light-transmitting panel 211. The fixed connection methods between the door frame 213 and the inner light-transmitting panel 211 include, but are not limited to, snap-fitting and adhesive bonding.

[0176] In this embodiment, the door frame 213 surrounds the edge of the inner light-transmitting panel 211. A portion of the door frame 213 is located on the front surface of the inner light-transmitting panel 211 facing away from the storage cavity 201, facilitating the fixing of the outer light-transmitting panel 214 mentioned below. A portion of the door frame 213 is located on the peripheral side of the inner light-transmitting panel 211, serving to shield the peripheral side of the inner light-transmitting panel 211, thus creating a good appearance for the drawer door 210. The door frame 213 is not located on the surface of the inner light-transmitting panel 211 facing the storage cavity 201, reserving space for the installation of the door seal 212.

[0177] It should be noted that the door frame 213 can be a single, integrally molded component, providing structural stability and contributing to the structural strength of the drawer door 210. Alternatively, the door frame 213 can be a separate structure. For example, the door frame 213 may include a rectangular frame and two side frames 2134. The rectangular frame defines a viewing window 2131, and the two side frames 2134 are respectively fixed to the inner side of the rectangular frame along its width, forming a receiving cavity for accommodating a portion of the locking mechanism described later.

[0178] In this embodiment of the application, the door frame 213 includes four frames, namely a top frame 2132, a bottom frame 2133 and two side frames 2134. The top frame 2132 and the bottom frame 2133 extend along the width direction of the drawer body 200 and are opposite to each other and spaced apart along the height direction of the drawer body 200. The top ends of the two side frames 2134 are respectively connected to the two ends of the top frame 2132, and the bottom ends of the two side frames 2134 are respectively connected to the two ends of the bottom frame 2133.

[0179] Continue to refer to Figure 6 Along the pull-out direction of the drawer body 200, the protrusion 2111 of the inner light-transmitting plate 211 can be opposite to the viewing window 2131. This allows light inside the storage cavity 201 to pass through the relatively smooth protrusion 2111 and then be emitted through the viewing window 2131. This helps improve the clarity of the user's observation of the inside of the storage cavity 201 through the viewing window 2131 and avoids complex light convergence caused by the folding point between the protrusion 2111 of the inner light-transmitting plate 211 and the flat plate in the central area of ​​the viewing window 2131, which would affect the clarity of observation.

[0180] Continue to refer to Figure 6In this embodiment of the application, the drawer door 210 may further include an outer light-transmitting panel 214, which is fixed to the outside of the door frame 213 and covers the viewing window 2131. The area of ​​the outer light-transmitting panel 214 opposite to the viewing window 2131 forms a light-transmitting area 202.

[0181] Along the pull-out direction of the drawer body 200, there is a gap between the outer light-transmitting panel 214 and the inner light-transmitting panel 211, which can prevent the deformation of the inner light-transmitting panel 211 from affecting the outer light-transmitting panel 214. Moreover, this gap isolates the inner light-transmitting panel 211 and the outer light-transmitting panel 214. When the outer light-transmitting panel 214 is subjected to external impact (such as the impact when taking out or putting in items), this gap can prevent the external force from being directly transmitted to the inner light-transmitting panel 211, greatly reducing the risk of direct damage and breakage of the inner light-transmitting panel 211.

[0182] For example, the outer light-transmitting panel 214 is bonded to the outer surface of the door frame 213 to avoid the appearance being affected by the protruding connection structure.

[0183] In some embodiments, a decorative frame 215 may be provided on the outer surface of the outer light-transmitting panel 214 away from the door frame 213. The decorative frame 215 is annular. The hollow area enclosed by the decorative frame 215 may be opposite to the viewing window 2131, or the inner edge of the decorative frame 215 may be located within the viewing window 2131. The area in the middle of the decorative frame 215 forms a light-transmitting area 202.

[0184] The decorative frame 215 can be attached to the outer surface of the outer light-transmitting panel 214. The decorative frame 215 can also be screen-printed with patterns on the outer surface of the outer light-transmitting panel 214. Of course, the decorative frame 215 can also be set on the outer surface of the outer light-transmitting panel 214 in other ways, without any restrictions.

[0185] By setting up the decorative frame 215, it can both cover the connection between the door frame 213 and the outer light-transmitting panel 214 and serve a decorative purpose, and also make the light-transmitting area 202 more prominent.

[0186] In some embodiments of this application, the outer surface of the outer light-transmitting plate 214 does not protrude beyond the outer end of the door frame 213 away from the storage cavity 201, which helps to form a flat appearance of the drawer door 210.

[0187] The drawer door 210 of this embodiment improves structural strength by providing an inner light-transmitting plate 211 and an outer light-transmitting plate 214, and by designating a portion of the inner light-transmitting plate 211 as a protrusion 2111, thus enabling it to withstand the pressure of the low-pressure storage environment of the vacuum drawer 30. A door frame 213 provides an installation position for the inner light-transmitting plate 211 and the outer light-transmitting plate 214.

[0188] The double-layer light-transmitting panel makes the vacuum drawer 30 transparent, allowing the storage status inside the storage cavity 201 to be observed through the light-transmitting area 202 of the drawer door 210 without opening the drawer body 200. This improves the convenience of using the vacuum drawer 30 and also helps to reduce the energy consumption of the refrigerator.

[0189] The pressure relief hole 220 on the drawer door 210 has an inner end facing the drawer cavity 102 and an outer end facing the external environment. The outer end of the pressure relief hole 220 faces the pressure relief component 400. The inner end of the pressure relief hole 220 can be directly connected to the drawer cavity 102, allowing outside air to directly enter the drawer cavity 102 through the pressure relief hole 220, thus achieving pressure relief. Alternatively, the pressure relief hole 220 can be indirectly connected to the drawer cavity 102 through a gap, also achieving pressure relief of the drawer cavity 102.

[0190] The following is combined with Figures 5 to 7 Describe the pressure relief structure and pressure relief path. For example... Figure 7 As shown, a first hole section 221 is provided in the area where the inner light-transmitting plate 211 is opposite to the bottom edge of the door frame 213, and the first hole section 221 is connected to the drawer cavity 102.

[0191] like Figure 7 As shown, the bottom edge 2133 of the door frame 213 is provided with a through hole 2135, the diameter of which is larger than the diameter of the pressure relief hole 220. The drawer door 210 may also include a seal 216, which is installed between the door frame 213 and the inner light-transmitting plate 211 and is used to seal the bottom edge 2133 and the inner light-transmitting plate 211. The seal 216 is provided with a second hole section 222, which communicates with and is coaxially arranged with the first hole section 221. The end of the second hole section 222 facing away from the first hole section 221 communicates with the external space of the drawer cavity 102. Thus, the pressure relief hole 220 includes the first hole section 221 provided on the inner light-transmitting plate 211 and the second hole section 222 provided on the seal 216.

[0192] Continue to refer to Figure 6 and Figure 7 A raised ring 2112 is provided on the side of the inner light-transmitting plate 211 facing the bottom frame 2133, and the raised ring 2112 surrounds the outside of the first hole section 221. The sealing member 216 is constructed to form a groove facing the opening of the inner light-transmitting plate 211, and the groove is located on the periphery of the second hole section 222. The groove is fitted onto the outside of the raised ring 2112 to achieve a fixed connection between the inner light-transmitting plate 211 and the sealing member 216.

[0193] One end of the seal 216 facing the bottom frame 2133 extends into the through hole 2135, with a gap between the seal 216 and the wall of the through hole 2135. The pressure relief component 400 seals with the seal 216 via the through hole 2135, such as... Figure 7As shown, the pressure relief component 400 is used to close the pressure relief hole 220. By setting a through hole 2135 on the bottom frame 2133, the pressure relief component 400 driven by the handle 410 can be precisely aligned and enter the second hole section 222, which restricts the movement of the pressure relief component 400, prevents it from deviating or jamming, and ensures smooth and reliable operation.

[0194] The door frame 213 is made of metal or high-strength plastic. It is more appropriate for the door frame 213 to bear the force and wear brought by the pressure relief component 400 during the pressure relief operation than for the inner light-transmitting plate 211 or the sealing component 216 to bear it directly. This helps to protect the inner light-transmitting plate 211 and the sealing component 216.

[0195] Both the sealing element 216 and the pressure relief element 400 are elastomers, such as silicone or rubber, which facilitate elastic deformation to improve the reliability of the pressure relief element 400 in sealing the pressure relief hole 220.

[0196] like Figure 7 As shown, the red line represents the path of gas entering the drawer cavity 102 during pressure relief. When the handle 410 moves the pressure relief component 400 away from the seal 216, the pressure relief hole 220 on the seal 216 is opened. Outside air enters the pressure relief hole 220 through the through hole 2135; then it enters the drawer cavity 102 through the gap between the inner light-transmitting plate 211 and the drawer bottom wall 231, thereby causing the air pressure inside the drawer cavity 102 to approach the air pressure of the outside environment, thus achieving pressure relief.

[0197] In this embodiment, by arranging the pressure relief hole 220 on the bottom side of the light-transmitting area 202 and mounting it on the door frame 213, the pressure relief component 400 can be prevented from occupying the middle area of ​​the drawer door 210 and affecting the visibility of the vacuum drawer 30. Furthermore, the gap between the inner light-transmitting plate 211 and the drawer bottom wall 231 is creatively utilized to form an air intake path, ensuring pressure relief while making the pressure relief hole 220 more peripheral, thus providing a basis for a large light-transmitting area 202.

[0198] Continue to refer to Figure 6 and Figure 7 In this embodiment, the handle 410 is movably connected to the door frame 213, wherein the handle 410 is rotatably connected to the door frame 213 to drive the pressure relief component 400 to close or open the pressure relief hole 220. The handle 410 is located below the outer light-transmitting plate 214 to avoid the handle 410 affecting the light-transmitting area 202.

[0199] The bottom edge 2133 of the door frame 213 has a recess 2136, which is recessed relative to the portion of the outer light-transmitting panel 214 fixed to the door frame 213, facing the storage cavity 201. A handle 410 is located in the recess 2136 to accommodate at least a portion of the handle 410, reducing the portion of the handle 410 protruding from the outer light-transmitting panel 214 and improving the structural compactness of the drawer door 210. Furthermore, a gap is formed between the rear surface of the handle 410 and the front surface of the recess 2136, facilitating the insertion of a user's hand to move the handle 410 relative to the drawer door 210.

[0200] In this embodiment, the pressure relief component 400 is disposed on the side of the handle 410 facing the door frame 213, so that the pressure relief component 400 faces the pressure relief hole 220, which facilitates sealing and opening the pressure relief hole 220; moreover, the pressure relief component 400 is hidden behind the handle 410, which helps to improve the aesthetics of the drawer body 200, so that the vacuum drawer 30 has a simple, complete and non-redundant visual appearance, minimizing the interference of functional components on the overall appearance.

[0201] Furthermore, by using the handle 410 to shield the pressure relief component 400, the handle can also become a protective component for the pressure relief component 400, which can effectively prevent external forces from directly acting on the pressure relief component 400 during daily cleaning, moving items or accidental collisions, greatly reducing the risk of damage to it and improving the reliability and lifespan of the product.

[0202] Continue to refer to Figure 6 and Figure 7 The pressure relief component 400 is located at one end of the handle 410 in the extension direction. To avoid noise caused by rigid contact between the other end of the handle 410 and the door frame 213, a buffer component 217 is provided on the door frame 213. The buffer component 217 makes elastic contact with the side of the handle 410 away from the pressure relief component 400. The buffer component 217 can be an elastic pad installed on the bottom frame 2133, such as a silicone pad or a rubber pad.

[0203] Furthermore, by setting the buffer 217, the handle 410 can be subjected to balanced force along its length, ensuring the reliability of the pressure relief component 400 sealing the pressure relief hole 220.

[0204] With the above configuration, the vacuum drawer 30 of this application embodiment arranges the pressure relief component 400 on the edge of the drawer door 210, so that a single continuous light-transmitting area 202 with a large area is formed on the drawer door 210, which improves the convenience for users to directly observe the internal storage status of the storage cavity 201 through the drawer door 210.

[0205] Due to the large depth dimension of the storage cavity 201, coupled with the obstruction caused by the items stored inside the storage cavity 201, the visibility of the rear area of ​​the storage cavity 201 is weak and it is difficult to see clearly.

[0206] Therefore, referring to Figure 2 and Figure 3 The vacuum drawer 30 in this embodiment may also include a light module 600, which is installed on the drawer shell 100 and provides light to the storage cavity 201.

[0207] The lighting module 600 is installed on the part of the drawer shell 100 located above the top of the drawer body 200 to provide light to the storage cavity 201.

[0208] For example, the lighting module 600 can be installed on the top wall 110 of the drawer housing 100, with ample space for arrangement.

[0209] For example, the illumination module 600 can be disposed on the transition wall 150 connected to the top wall 110 of the housing to reduce the deformation effect of the vacuum environment on the illumination module 600.

[0210] In some embodiments of this application, the illumination module 600 is positioned close to the rear wall 120 of the drawer shell 100, which helps to increase the brightness of the rear end of the storage cavity 201, thereby helping to increase the brightness of the entire storage cavity 201, so as to improve the clarity of observation through the light-transmitting area 202.

[0211] In some possible implementations, the lighting module 600 may include a lighting lamp, which primarily provides illumination light.

[0212] In some other possible implementations, the lighting module 600 may include a preservation lamp, for example, a preservation lamp that emits blue light to improve the preservation effect of food inside the drawer body 200.

[0213] Continue to refer to Figure 2 and Figure 3 The vacuum drawer 30 in this embodiment may also include a camera 500, which is configured to capture images of the interior of the storage cavity 201.

[0214] The refrigerator may also include a controller, which is electrically connected to the illumination module 600 and the imaging device 500 respectively, to control the operating status of the illumination module 600 and the imaging device 500.

[0215] For example, after the controller receives the refrigerator door opening signal, the controller is configured to control the lighting module 600 to start, so as to emit light into the storage cavity 201, increase the light intensity in the storage cavity 201, and allow the user to clearly observe the storage status in the storage cavity 201 through the light-transmitting area 202 of the drawer door 210.

[0216] For example, after the controller receives a signal to view the storage status inside the vacuum drawer 30, the controller is configured to control the light module 600 to start and control the imaging device 500 to capture an internal image of the storage cavity 201, and display the internal image of the storage cavity 201 on the display device, thereby showing the user the storage status of the storage cavity 201.

[0217] The display device can be a display screen installed on the refrigerator door, or it can be a user's terminal device, such as a mobile phone or tablet computer.

[0218] In this way, users can obtain the storage status inside the storage cavity 201 through the imaging device 500 without opening the refrigerator door, which helps maintain the storage environment inside the refrigerator. Moreover, the cooperation between the light module 600 and the imaging device 500 ensures clear images of the inside of the storage cavity 201, and provides a foundation for intelligent food management such as food type identification and freshness calculation using the images of the storage cavity 201.

[0219] In some possible implementations, the controller uses technologies such as image recognition to determine the freshness of the food in the storage cavity 201 based on the image captured by the camera 500, and outputs a freshness alarm message when the freshness is less than a set value.

[0220] It should also be noted that by constructing a light-transmitting area 202 in the drawer door 210, light from the lighting fixture installed in the refrigerator's storage compartment can enter the vacuum drawer 30 through the light-transmitting area 202, providing light for the imaging device 500 to capture images. Thus, when the imaging device 500 captures images, not only can the lighting module 600 provide light, but the lighting fixture in the storage compartment can also provide light through the light-transmitting area 202, ensuring sufficient lighting inside the vacuum drawer 30.

[0221] Therefore, the refrigerator of this application embodiment, by constructing a light-transmitting area 202 in the drawer door 210 and setting the pressure relief component 400 on the outside of the light-transmitting area 202, achieves a large continuous light-transmitting area 202. Users can directly observe the storage status of food in the storage cavity 201 through the light-transmitting area 202 without opening the vacuum drawer 30, which is simple and convenient. This process does not require opening the vacuum drawer 30, reducing the frequency of vacuuming the vacuum drawer 30 and helping to reduce the energy consumption of the refrigerator.

[0222] Furthermore, in this embodiment of the vacuum drawer 30, a light module 600 is provided on the drawer shell 100 to provide light to the storage cavity 201, increase the light intensity in the storage cavity 201, improve the clarity of the food in the storage cavity 201 observed by the user through the light-transmitting area 202, and more accurately obtain the storage status in the storage cavity 201.

[0223] Furthermore, in this embodiment of the vacuum drawer 30, a photographing device 500 is provided on the drawer shell 100 to capture an image of the interior of the storage cavity 201. The illumination module 600 can enhance the light intensity inside the storage cavity 201, providing supplemental lighting for the image captured by the photographing device 500, which helps improve the clarity of the image captured by the photographing device 500. This allows the user to obtain the storage status of the storage cavity 201 through the image captured by the photographing device 500 without having to open the refrigerator door, further reducing the refrigerator's energy consumption.

[0224] In this way, users can directly observe the storage status of the storage cavity 201 through the light-transmitting area 202, and also determine the storage status of the storage cavity 201 through the image captured by the imaging device 500. This adds a way to obtain the storage status of the storage cavity 201 without opening the vacuum drawer 30, enriching the functions of the refrigerator and making its use more flexible and diverse.

[0225] With the above-mentioned configuration, the vacuum drawer 30 of this application embodiment provides a basis for setting a larger light-transmitting area 202 by arranging the pressure relief component 400 on the outside of the light-transmitting area 202 of the drawer door 210, thereby providing a basis for observing the storage state inside the storage cavity 201 without opening the vacuum drawer 30.

[0226] Based on this, the vacuum drawer 30 is equipped with a light module 600 to enhance the light intensity of the storage cavity 201 and improve the clarity of observing the storage status inside the storage cavity 201 through the light-transmitting area 202.

[0227] Based on this, the illumination module 600 provides the foundation for the imaging device 500 to capture images, which in turn provides the foundation for obtaining the storage status inside the storage cavity 201 through the images captured by the imaging device 500. Thus, the various functional settings of the vacuum drawer 30 are interconnected and mutually reinforcing, forming an organic whole. Users can clearly see the storage status inside the storage cavity 201 through the light-transmitting area 202, and can also obtain the storage status inside the storage cavity 201 through the clear images captured by the imaging device 500. This also provides the foundation for intelligent management by using the internal images of the storage cavity 201 to obtain information such as the type and freshness of the ingredients.

[0228] Continue to refer to Figure 2 and Figure 3In this embodiment, the imaging device 500 is installed at the connection between the top wall 110 and the rear wall 120 of the drawer shell 100. Specifically, the imaging device 500 is installed at the transition wall 150 between the top wall 110 and the rear wall 120. On one hand, the transition wall 150 between the top wall 110 and the rear wall 120 has high structural strength, and the low-pressure storage environment has little impact on the deformation of the transition wall 150, making the installation of the imaging device 500 more stable. On the other hand, the imaging device 500 is located at the rear end of the drawer shell 100, providing a convenient position for the imaging device 500 to capture images of the entire storage cavity 201, reducing blind spots and facilitating the capture of more comprehensive images.

[0229] Reference Figure 8 In some embodiments of this application, the illumination module 600 is mounted on the top wall 110 of the housing and located on the front side of the imaging device 500. The illumination module 600 is mounted on the top wall 110 of the housing, with ample installation space. By placing the illumination module 600 on the front side of the imaging device 500, it can provide light for the imaging device 500 to capture images, and also ensure that the light path towards the front drawer door 210 is not blocked by the imaging device 500, thus ensuring the clarity of the observation of the storage state inside the storage cavity 201 through the light-transmitting area 202 of the drawer door 210.

[0230] Continue to refer to Figure 8 Along the depth direction of the vacuum drawer 30, the distance between the light module 600 and the front end of the drawer shell 100 is greater than the distance between the light module 600 and the rear end of the drawer shell 100. Compared to the front end of the drawer shell 100, the light module 600 is closer to the rear end of the drawer shell 100, making the light module 600 closer to the shooting device 500.

[0231] For example, the lighting module 600 is located at the rear side of the drawer housing 100 at the middle position along the depth direction.

[0232] This helps optimize the lighting at the rear of the storage cavity 201, reducing or even eliminating dark areas and minimizing blind spots for observation and shooting. Furthermore, the proximity of the lighting module 600 to the shooting device 500 shortens the optical path distance between them, enhancing the lighting efficiency of the shooting device 500 and contributing to improved image quality.

[0233] Furthermore, the lighting module 600 is located near the rear end, ensuring that the light emitted primarily covers the rear part of the storage cavity 201, while the front area can utilize natural light. When the user observes through the light-transmitting area 202, the light will not shine directly into their eyes, reducing glare.

[0234] In some embodiments of this application, the illumination module 600 is arranged symmetrically with respect to the projection line of the optical axis of the imaging device 500 onto the top wall of the drawer shell 100. This can be understood as the illumination module 600 being symmetrical about the imaging device 500. The left-right direction corresponds to the width direction of the vacuum drawer 30.

[0235] This setup ensures that light is evenly projected from both sides of the shooting device 500's field of view, avoiding shadows or uneven brightness on the food caused by unilateral lighting and reducing shooting shadows. The optical axis projection line serves as a symmetry reference, ensuring that the coverage area of ​​the illumination module 600 precisely matches the shooting angle of the shooting device 500, reducing dark areas at the image edges, improving image uniformity, and providing a high-quality image foundation for intelligent food recognition (such as type and freshness analysis).

[0236] When the optical axis of the imaging device 500 is located at the midpoint of the width direction of the drawer shell 100, the illumination module 600 is symmetrical about the midpoint of the width direction of the drawer shell 100. This symmetrical layout utilizes the mechanical symmetry of the shell top wall 110 to reduce structural stress caused by unilateral installation, which helps to improve the stability of installation under low pressure. The symmetrical layout allows light to evenly cover the approximately 201 area of ​​the storage cavity, reducing the probability of local dark areas and helping to improve brightness uniformity.

[0237] Continue to refer to Figure 8 The illumination module 600 has a certain size along the depth direction of the drawer shell 100, giving it a certain illumination area. This allows the illumination module 600 to be positioned near the rear end of the drawer shell 100 to supplement the light at the rear end of the storage cavity 201; alternatively, it can be positioned near the middle of the depth direction of the drawer shell 100 to form a large supplementary lighting area. This helps to enhance the uniformity of light and brightness within the storage cavity 201, ensuring the clarity of direct observation and image formation.

[0238] Combination Figure 9 and Figure 10 In some embodiments of this application, the optical axis O of the imaging device 500 is tilted toward the drawer door 210 relative to the direction perpendicular to the horizontal plane, so that the imaging range of the imaging device 500 can cover the top wall 110 of the drawer shell 100, the bottom wall 231 of the storage cavity 201, and the rear wall 232 of the drawer, which helps to ensure the comprehensiveness of the captured image.

[0239] With the above setup, both the shooting device 500 and the lighting module 600 are mounted on the drawer shell 100 in a fixed position, and do not move with the pull-out of the drawer body 200. This simplifies the installation structure and helps to ensure the consistency between the shooting position and the light source position.

[0240] Mounting the imaging device 500 at the connection between the top wall 110 and the rear wall 120 of the drawer shell 100 improves the stability of the imaging device 500 installation and reduces deformation interference from the low-pressure storage environment. It also positions the imaging device 500 at the top rear end of the storage cavity 201, ensuring it can capture images of the entire storage cavity 201 from a forward angle. By tilting the imaging device 500, its optical axis O is tilted forward relative to the direction perpendicular to the horizontal plane, allowing the imaging range to cover the top wall 110 of the drawer shell 100, the bottom wall 231 of the drawer 201, and the rear wall 232 of the drawer. This helps ensure comprehensive image capture, guaranteeing a clear and complete understanding of the storage status of the storage cavity 201. Furthermore, the complementary light coverage and shooting angle ensure clear visibility of details of the food at the rear, preventing image blurring due to obstruction.

[0241] The illumination module 600 is installed on the top wall 110 of the housing and located in front of the imaging device 500. On the one hand, this allows the illumination module 600 to avoid the installation position of the imaging device 500, ensuring that both the illumination module 600 and the imaging device 500 have sufficient installation space. On the other hand, the illumination module 600 is located in front of the imaging device 500, which can provide light for the imaging device 500 to capture images, and also allows the light to shine directly forward through the light-transmitting area 202 of the drawer door 210 without being blocked by the imaging device 500, ensuring the clarity of the internal storage status observed through the light-transmitting area 202.

[0242] This embodiment of the application, through the coordination of the installation position of the shooting device 500, the installation position of the illumination module 600, and the tilt angle of the optical axis O of the shooting device 500, ensures the reliability of the installation of the shooting device 500 and the illumination module 600, ensures sufficient light for the captured image, and ensures sufficient light for direct observation of the storage state inside the storage cavity 201 through the light-transmitting area 202.

[0243] In summary, the refrigerator of this application embodiment has at least the following technical effects:

[0244] First, the synergistic optimization of visualization and image clarity is achieved: by placing the pressure relief component 400 on the outside of the light-transmitting area 202, the obstruction of the viewing line by the pressure relief structure in traditional designs is avoided, allowing the drawer door 210 to form a large, continuous light-transmitting area 202. Users can directly observe the interior of the storage cavity 201 without pulling out the drawer, reducing the disruption of the vacuum environment caused by frequent pulling and lowering the frequency of vacuuming, thereby extending the device's lifespan and saving energy. Simultaneously, the lighting module 600 is located on the front of the shooting device 500, providing supplemental lighting for the camera while avoiding obstruction of the light path to the light-transmitting area 202, ensuring clarity for both direct user observation and image capture.

[0245] Secondly, structural stability and functional reliability under low-pressure environments: The drawer door 210 adopts a double-layer structure of inner light-transmitting panel 211 + outer light-transmitting panel 214, and the inner light-transmitting panel 211 is designed with a protrusion 2111 to enhance the resistance to pressure deformation and ensure the sealing and durability of the vacuum drawer 30 under low-pressure environments. The pressure relief component 400 is controlled by the handle 410 and is hidden on the bottom edge of the drawer door 210, which optimizes the appearance and ensures the convenience of pressure relief operation.

[0246] Furthermore, the systematic optimization of spatial layout and optical path design: the shooting device 500 is installed at an angle at the connection between the top wall 110 and the rear wall 120 of the housing, with the optical axis tilted forward, so that its shooting range covers the rear wall and top wall of the storage cavity 201, reducing shooting blind spots and ensuring the comprehensiveness of the captured images.

[0247] Furthermore, the establishment of a foundation for intelligent management: sufficient light and clear images provide a high-quality data foundation for intelligent functions such as food type identification and freshness analysis. Users can remotely view the food storage status in storage compartment 201 through the refrigerator door screen or mobile terminal, reducing the number of times the door is opened and maintaining stable temperature.

[0248] The refrigerator in this embodiment of the application achieves the organic integration of three functions: low-pressure preservation, visual observation, and intelligent monitoring through the external placement of the pressure relief component 400, the maximization of the light-transmitting area 202, and the coordinated layout of the imaging device 500 and the light module 600, forming a complete technical solution that takes into account both user experience and energy efficiency.

[0249] It should be noted that the imaging device 500 in this embodiment is fixed to the drawer shell 100, meaning that the imaging device 500 does not expand the imaging range by moving relative to the drawer shell 100; moreover, only one imaging device 500 is provided. By coordinating the position, installation angle, and position of the imaging device 500 with the illumination module 600, a large imaging range and clear image can be achieved. The vacuum drawer 30 in this embodiment has a simple structure, few parts, and is easy to implement.

[0250] Continue to refer to Figure 8 In some embodiments of this application, the drawer body 200 has a center surface M, which is perpendicular to both the horizontal plane and the rear side surface of the box 10. Figure 1 In the directions shown, the center plane M is parallel to the YZ plane. Figure 9 This is a cross-sectional view of the vacuum drawer 30 on the center plane M.

[0251] In this embodiment of the application, the optical axis O of the shooting device 500 is located on the center plane M of the drawer body 200, so that the shooting device 500 is arranged at the middle position of the drawer shell 100 along the width direction.

[0252] With this configuration, the optical axis O is arranged along the center plane of the drawer body 200, avoiding image distortion caused by viewing angle shifts and providing data support for more accurate food positioning. Moreover, the shooting device 500 is centered in the width direction, and there is no trajectory interference with the pull-out trajectory of the drawer body 200, which can ensure the consistency of the position of the shooting device 500 during repeated pull-out of the drawer body 200.

[0253] Based on this, the light module 600 is symmetrically arranged with respect to the projection of the optical axis of the shooting device 500 onto the top wall of the drawer shell 100. In this way, the light source is centered with respect to the width direction, and the shooting angle is also centered with respect to the width direction, ensuring a precise match between the light path and the viewing angle. This helps eliminate image distortion, avoids asymmetrical shadows and image edge distortion caused by unilateral lighting, and improves the accuracy of food recognition.

[0254] Combination Figure 9 In some embodiments of this application, the optical axis O of the imaging device 500 forms an angle α with the horizontal plane.

[0255] For ease of explanation, the shooting device 500 in this embodiment has a preset shooting angle. The shooting angle is related not only to the characteristics of the camera 540 itself, but also to the mounting holes at the mounting position of the camera 540. (In conjunction with...) Figure 9 The red line represents the top boundary line of the imaging device 500; the blue line represents the bottom boundary line of the imaging device 500. The angle between the red and blue lines is the field of view. In reality, the shooting angle of the camera 540 is an approximate radial cone (of course, in actual optical systems, due to lens design and the shape of the imaging sensor, the complete field of view is a pyramid-shaped four-sided pyramid). Both the red and blue lines are lines on the surface of the cone, and this cone-shaped surface can be understood as the boundary of the image.

[0256] If the included angle α is less than 30°, the optical axis O is close to the horizontal plane, causing the viewing angle of the shooting device 500 to be overly concentrated on the top wall 110 of the storage cavity 201, while the blind spots of the rear and bottom walls of the storage cavity 201 are expanded, thus limiting the shooting range; it is impossible to fully cover the food inside the storage cavity 201, affecting the integrity of the image and the basic data quality of the intelligent recognition function.

[0257] If the included angle α is greater than 60°, the optical axis O is too close to the direction perpendicular to the horizontal plane, causing the shooting angle to be too downward and over-focused on the bottom wall of the storage cavity 201, which may result in the area behind the top wall of the storage cavity 201 not being able to be photographed. Moreover, the angle tending to be perpendicular to the horizontal plane may increase light reflection, causing image overexposure and affecting image clarity.

[0258] In this embodiment, the included angle α is 30° to 60°, so that the shooting range of the shooting device 500 includes the inner surface of the top wall 110 and the inner surface of the rear wall 120. For example, the included angle α is 45°.

[0259] With this configuration, the shooting range of the shooting device 500 can simultaneously cover the inner surface of the top wall 110 and the inner surface of the rear wall 120 of the shell, enabling more comprehensive shooting of the interior of the storage cavity 201, reducing blind spots, improving image quality and the reliability of food identification; ensuring that high-quality and comprehensive images of the storage cavity 201 can still be obtained under the premise that the shooting device 500 and the shooting position are fixed.

[0260] In some embodiments, the angle α between the optical axis O of the imaging device 500 and the horizontal plane is such that the mounting angle of the imaging device 500 is between a first position and a second position. In the first position, the top side boundary line of the imaging device 500 ( Figure 9 The red line in the middle is parallel to the horizontal plane, and the bottom boundary line of the shooting device 500 ( Figure 9 The blue line in the middle is tilted backward relative to the rear wall 120 of the shell; in the second position, the bottom boundary line of the imaging device 500 ( Figure 9 The blue line extends along the height direction, and the top edge boundary line of the shooting device 500 ( Figure 9 The red line in the middle is parallel to the horizontal plane and tilts upwards.

[0261] The mounting position of the shooting device 500 between the first position and the second position helps to ensure that a wide range of comprehensive shooting can be achieved using a single and fixed-position camera 540, reducing blind spots and improving the comprehensiveness of the image.

[0262] In some embodiments of this application, reference is made to Figure 6 The drawer body 200 has a rear wall 232 with a clearance notch 2321 that extends downward from the top of the rear wall 232. Along the height of the drawer body 200, the clearance notch 2321 is opposite to the shooting device 500.

[0263] When the drawer body 200 is pushed into the drawer cavity 102, there is usually a gap between the drawer rear wall 232 and the shell rear wall 120 of the drawer body 200. By providing an avoidance notch 2321 in the drawer rear wall 232, a "window" is opened for the imaging device 500 to capture images of the rear part of the storage cavity 201, reducing the obstruction of light from the camera 540 by the drawer rear wall 232. This allows light from the rear of the storage cavity 201 to be captured by the imaging device 500 through the avoidance notch 2321, enabling visualization of the rear and bottom areas of the storage cavity 201, reducing the occurrence of blind spots, and helping to expand the actual effective monitoring range of the imaging device 500. This allows even a single camera 540 in a fixed position to obtain near-panoramic monitoring capabilities within the storage cavity 201.

[0264] Compared to using a movable camera 540 or a complex optical system, this method solves the major field-of-view obstruction problem with just a simple static structural modification, offering high reliability and low cost.

[0265] The clearance notch 2321 has two opposite sides along the width direction. The distance between the two sides decreases from top to bottom along the height direction, making the clearance notch 2321 wider at the top and narrower at the bottom. This facilitates the demolding of the drawer body 200 and minimizes obstruction of light for image capture, ensuring image quality.

[0266] Combination Figure 10 , Figure 11 as well as Figure 12 In some embodiments of this application, a first mounting hole 1511 is provided on the drawer shell 100. The first mounting hole 1511 is provided on the transition wall 150 between the top wall 110 and the rear wall 120 of the shell.

[0267] In some embodiments of this application, the drawer shell 100 is configured to form a mounting inclined wall 151, which intersects with the top wall 110 and the rear wall 120 of the shell, respectively. A first mounting hole 1511 is provided on the mounting inclined wall 151. The axial direction of the first mounting hole 1511 is parallel to the normal direction of the mounting inclined wall 151, so that the optical axis O of the imaging device 500 is perpendicular to the mounting inclined wall 151. The direction of the optical axis O of the imaging device 500 is determined by the tilt angle of the mounting inclined wall 151, which helps to simplify the installation structure of the imaging device 500, simplify the function implementation, and reduce costs.

[0268] Continue to refer to Figure 10 The shooting device 500 may include: a first light-transmitting cover 510, which covers the first mounting hole 1511 and has a first sealing member 520 disposed between it and the drawer shell 100. The first sealing member 520 seals the first light-transmitting cover 510 and the mounting inclined wall 151.

[0269] The first light-transmitting cover 510 includes a first light-transmitting portion 511 and a first fixing portion 512. The first light-transmitting portion 511 is embedded into the first mounting hole 1511. The first fixing portion 512 is formed on the edge of the first light-transmitting portion 511 and abuts against the mounting inclined wall 151. A first sealing member 520 is provided between the first fixing portion 512 and the mounting inclined wall 151 to ensure the sealing of the shooting device 500 installed in the drawer shell 100, thereby ensuring the sealing of the drawer cavity 102.

[0270] like Figure 10 As shown, the shooting device 500 may also include a camera housing 530, which is connected to the drawer housing 100.

[0271] For example, the camera housing 530 is snapped into the drawer housing 100, which is a simple connection method and helps to improve assembly efficiency; moreover, it can also avoid increasing the risk of air leakage in the drawer cavity 102 by drilling holes in the drawer housing 100.

[0272] Reference Figure 13 The drawer shell 100 is also constructed to form a mounting enclosure 152, which is connected to the mounting inclined wall 151 to form a mounting groove with an upward opening. A first slot 1521 is provided on the mounting enclosure 152, and a snap-fit ​​flange 531 is provided on the edge of the camera shell 530. The snap-fit ​​flange 531 is inserted into the first slot 1521 to achieve snap-fit ​​between the camera shell 530 and the drawer shell 100. Furthermore, the snap-fit ​​position between the camera shell 530 and the drawer shell 100 is located outside the first sealing member 520, and does not affect the sealing of the drawer cavity 102.

[0273] In some embodiments of this application, the camera housing 530 and the drawer housing 100 are connected by a rotating snap-fit ​​method.

[0274] Reference Figure 14 and Figure 15 A limiting wall 1522 is provided on the inner surface of the mounting enclosure 152. Along the axial direction of the first mounting hole 1511, the limiting wall 1522 and the mounting inclined wall 151 are opposite to each other and spaced apart. Thus, a first groove 1521 is formed between the limiting wall 1522, the mounting inclined wall 151 and the mounting enclosure 152.

[0275] The limiting wall 1522 extends circumferentially along the mounting enclosure 152, and multiple limiting walls 1522 are spaced apart circumferentially along the mounting enclosure 152, thus forming multiple segments of first slots 1521 circumferentially along the mounting enclosure 152. For example, three limiting walls 1522 are spaced apart circumferentially along the mounting enclosure 152, forming three segments of first slots 1521 circumferentially along the mounting enclosure 152. A slotting inlet 1523 is formed between adjacent limiting walls 1522 circumferentially along the mounting enclosure 152, such that the number of slotting inlets 1523 is the same as the number of first slots 1521.

[0276] Correspondingly, such as Figure 14 As shown, the camera housing 530 has multiple snap-fit ​​flanges 531 on its edge, and the multiple snap-fit ​​flanges 531 are arranged at intervals along the circumference of the camera housing 530. The number of snap-fit ​​flanges 531 is the same as the number of first slots 1521.

[0277] During assembly, the snap-fit ​​flange 531 is first aligned with the snap-fit ​​inlet 1523. Then, the camera housing 530 is rotated so that the snap-fit ​​flange 531 enters the first slot 1521, thereby restricting the axial freedom of the camera housing 530 along the first mounting hole 1511. This assembly method is simple and convenient, helping to improve assembly efficiency. A rotation arrow can also be provided on the outer surface of the camera housing 530 as an indicator of the rotation direction during installation, further improving assembly efficiency.

[0278] In some embodiments, by setting a gap between the limiting wall 1522 and the mounting inclined wall 151, the gap between the limiting wall 1522 and the mounting inclined wall 151 along the axial direction of the first mounting hole 1511 gradually decreases along the rotation direction when the camera housing 530 is installed, so that the camera housing 530 gradually becomes more tightly pressurized with the rotation direction, thereby restricting the circumferential degree of freedom of the camera housing 530 and limiting the rotation termination position of the camera housing 530.

[0279] In other embodiments, a limiting protrusion is provided at the end of the first slot 1521. When the locking flange 531 abuts against the limiting protrusion, it indicates that the camera housing 530 is installed in place. The limit of rotational installation is obvious, which makes it easy to stop the rotation in time and avoid damage to the camera housing 530 due to excessive rotation.

[0280] To improve the ease of rotating the camera housing 530, a handle, such as a cross-shaped protrusion, is provided on the outer surface of the camera housing 530 away from the first light-transmitting cover 510, providing a force application point for the installation of the camera housing 530.

[0281] Refer again Figure 10 and Figure 13 A first receiving cavity 532 is formed between the camera housing 530 and the first light-transmitting cover 510. The shooting device 500 may also include a camera 540, which is located in the first receiving cavity 532 and is fixedly connected to the camera housing 530.

[0282] For example, the camera 540 and the camera housing 530 can be fixedly connected by screws to ensure the stability of the position between the camera 540 and the camera housing 530 and to prevent the camera 540 from shifting due to the installation of the camera housing 530.

[0283] Continue to refer to Figure 10 and Figure 13The first light-transmitting cover 510 has a first groove 513, which opens towards the camera housing 530. Part of the camera 540 extends into the first groove 513. This arrangement allows the camera 540 to extend into the drawer cavity 102, reducing the impact of the first mounting hole 1511 on the shooting angle.

[0284] In some embodiments of this application, the imaging device 500 may further include a heating element 550, which is installed in the first groove 513 and contacts the bottom wall of the first groove 513 to heat the first light-transmitting cover 510, thereby reducing the fogging of the first light-transmitting cover 510 caused by the low temperature environment in the drawer cavity 102, which would affect the clarity of the image.

[0285] The heating element 550 can be ring-shaped and located between the camera 540 and the sidewall of the first groove 513 to prevent the heating element 550 from directly contacting the camera 540, thereby increasing the heat of the camera 540 and affecting its service life.

[0286] In some embodiments of this application, the first light-transmitting cover 510 can be bonded to the first sealing component 520, and the first sealing component 520 is bonded to the mounting inclined wall 151, thereby fixing the first light-transmitting cover 510 to the mounting inclined wall 151, while ensuring the relative position between the first sealing component 520 and the mounting inclined wall 151, which helps to ensure the airtightness of the drawer cavity 102.

[0287] In other embodiments of this application, the camera housing 530 abuts against the area of ​​the first light-transmitting cover 510 outside the first mounting hole 1511, so as to press the first light-transmitting cover 510 tightly against the drawer housing 100. Specifically, the camera housing 530 abuts against the first fixing portion 512 of the first light-transmitting cover 510, thereby pressing the first light-transmitting cover 510 tightly against the drawer housing 100.

[0288] Combination Figure 14 The camera housing 530 has a protruding pressing part 533 on its inner surface facing the first receiving cavity 532. The pressing part 533 abuts against the first fixing part 512, thereby pressing the first light-transmitting cover 510 against the drawer shell 100. With this configuration, no additional fixing structure is required. The first light-transmitting cover 510 is fixed at the same time as the camera housing 530 is installed, which simplifies the assembly steps and improves assembly efficiency.

[0289] With the above-described configuration, the imaging device 500 of this embodiment provides a first mounting hole 1511 on the opaque drawer shell 100, providing a structural basis for the imaging device 500 to pick up light from the storage cavity 201 to form an image. By providing a first light-transmitting cover 510, light transmission is ensured while sealing the first mounting hole 1511; and a first sealing component 520 between the first light-transmitting cover 510 and the drawer shell 100 ensures the airtightness of the drawer cavity 102 in a vacuum environment, preventing air leakage in a low-pressure environment. By providing a camera housing 530 that snaps into the drawer shell 100 and forms a first receiving cavity 532 with the first light-transmitting cover 510, the camera 540 is accommodated and installed, providing external protection for the camera 540. By utilizing the area where the camera housing 530 and the first light-transmitting cover 510 are located outside the first mounting hole 1511, the first light-transmitting cover 510 is pressed tightly against the drawer housing 100, thereby fixing the first light-transmitting cover 510 relative to the drawer housing 100, simplifying the assembly steps and improving assembly efficiency; at the same time, it ensures that the optical path of the camera 540 is unobstructed.

[0290] In some embodiments of this application, the first light-transmitting cover 510 protrudes from the inner surface of the mounting inclined wall 151 toward the inner surface of the drawer cavity 102. The protruding first light-transmitting cover 510 effectively pushes the "viewing window" of the camera 540 into the drawer cavity 102, bringing it closer to the storage space. This effectively reduces the obstruction of the edge light of the camera 540 by the hole wall of the first mounting hole 1511, thereby maximizing the use of the physical field of view of the camera 540 itself and making the shooting range wider. Moreover, for the camera 540 installed in the corner (the connection between the top wall 110 and the rear wall 120 of the housing), the design of the protruding first light-transmitting cover 510 is particularly beneficial for reducing the blind spot at close range, allowing the camera 540 to "see" the side and lower area closer to the installation position.

[0291] In other embodiments of this application, reference is made to Figure 13 The inner surface of the first light-transmitting cover 510 does not protrude from the inner surface of the mounting inclined wall 151, and the hole wall of the first mounting hole 1511 is provided with an inclined surface 1512 facing the inner end of the drawer cavity 102; along the direction from the outer end to the inner end of the first mounting hole 1511, the inclined surface 1512 is inclined away from the optical axis O of the camera 540.

[0292] For example, the angle between the inclined surface 1512 and the optical axis O can be 45°.

[0293] The inclined surface 1512 causes the inner end of the first mounting hole 1511 to tilt away from the optical axis O of the camera 540, forming an "opening" design at the inner end of the first mounting hole 1511, which actively avoids the light path and prevents the hole wall from blocking the light and affecting the shooting range.

[0294] By employing the two methods described above, the theoretical field of view of the camera 540 can be converted into the actual shooting field of view with minimal loss, which helps to improve image integrity, eliminate edge vignetting and distortion, and improve the clarity of the captured image.

[0295] Reference Figure 16 In some embodiments of this application, two illumination modules 600 are provided, and the two illumination modules 600 are symmetrically arranged about the center line O1 of the drawer shell 100; wherein, the center line O1 of the drawer shell 100 extends along the depth direction of the box 10, and the drawer shell 100 is symmetrical about the center line O1.

[0296] This embodiment of the application enhances the light intensity within the storage cavity 201 by incorporating two lighting modules 600. The two lighting modules 600 are symmetrically positioned at their center along the width direction, ensuring even light coverage from both sides of the storage cavity 201 and preventing shadows or uneven brightness caused by unilateral lighting. This symmetrical arrangement of the two lighting modules 600 also utilizes the mechanical symmetry of the shell top wall 110 to reduce stress concentration caused by unilateral loads, thus enhancing module stability under low-pressure environments.

[0297] Continue to refer to Figure 16 In some implementations, a first gap L1 exists between the rear end of the illumination module 600 and the rear wall 120 of the housing. This first gap L1 is less than one-quarter of the depth dimension D of the drawer cavity 102. That is, .

[0298] Understandably, the installation position of the lighting module 600 can avoid the transition wall 150 between the top wall 110 and the rear wall 120 of the housing, making the installation of the lighting module 600 simpler. When the rear end of the lighting module 600 contacts the edge of the transition wall 150, the first gap L1 is at its minimum value.

[0299] This arrangement places the lighting module 600 close to the rear of the storage cavity 201, allowing the light to directly illuminate the rear wall and corners of the storage cavity 201. This helps to eliminate dark areas at the rear and improves the consistency of brightness between the front and back when the user observes through the light-transmitting area 202.

[0300] Continue to refer to Figure 16 In some implementations, the illumination module 600 has a second gap L2 between it and the shell sidewall 130 of the adjacent drawer shell 100, the second gap L2 being less than one-third of the width dimension W of the drawer cavity 102. That is, .like Figure 16 As shown, there is a second gap L2 between the left illumination module 600 and the left shell sidewall 130, and there is a second gap L2 between the right illumination module 600 and the right shell sidewall 130.

[0301] When the dimension W of the drawer cavity 102 varies along the width direction and the depth direction, the aforementioned dimension W can be the average value of the dimension of the drawer cavity 102 along the width direction. Alternatively, the aforementioned dimension W can also be the width of the drawer cavity 102 at the midpoint along the depth direction.

[0302] Understandably, the installation position of the illumination module 600 can avoid the transition wall 150 between the top wall 110 and the side wall 130 of the housing, making the installation of the illumination module 600 simpler. When the side of the illumination module 600 away from the center line O1 contacts the edge of the transition wall 150 of the adjacent side wall 130 of the housing, the second interval L2 is at its minimum value.

[0303] By defining the second interval L2, the illumination module 600 is positioned close to the side wall 130 of the housing but at an appropriate distance, preventing the light from being blocked by the side wall 130 of the housing, while simultaneously expanding the coverage of the light on the side wall area of ​​the storage cavity 201, thus reducing blind spots during shooting.

[0304] Combination Figure 17 In some embodiments of this application, the main light direction O2 of the illumination module 600 is parallel to the height direction of the housing 10. In this way, the light is projected vertically downward, avoiding the light from shining directly on the rear wall 120 of the housing and causing reflection interference to the shooting device 500. It can also avoid glare caused by the light shining forward, which would affect the user's comfort in direct observation.

[0305] In other embodiments, the main light beam of the illumination module 600 is tilted forward relative to the height direction of the housing 10. The light beam is tilted forward and downward, preferentially covering the front part of the storage cavity 201, enhancing the brightness for direct observation by the user through the light-transmitting area 202, while providing forward supplementary lighting for the shooting device 500 and reducing the risk of reflection from the rear wall.

[0306] The main light beam of the illumination module 600 can be directed downwards or forwards to prevent strong light from directly hitting the lens of the camera 540 and causing glare or overexposure.

[0307] The main ray direction of the illumination module 600 refers to the direction of light propagation where the light intensity is greatest and the energy is most concentrated. When the illumination module 600 includes LED lights, the peak light intensity direction is the main ray direction.

[0308] The direction of the main ray is the normal direction of the center of the light-emitting surface. When the lighting module 600 includes the lamp board 650, the direction of the main ray is perpendicular to the surface of the lamp board 650.

[0309] Reference Figure 18 In some embodiments of this application, the top wall 110 of the shell is provided with a second mounting hole 111, which provides a channel for the light from the illumination module 600 to enter the storage cavity 201.

[0310] like Figure 18 As shown, the lighting module 600 may include a second light-transmitting cover 610, which is located inside the drawer cavity 102 and is snapped onto the top wall 110 of the housing. While allowing light to pass through, the second light-transmitting cover 610 also serves to decorate and protect the electrical components inside the lighting module 600.

[0311] For example, the second light-transmitting cover 610 includes a snap-fit ​​portion 612 and a cover portion 611. The cover portion 611 is located on the inner surface of the top wall 110 of the housing, and the snap-fit ​​portion 612 is connected to the top surface of the cover portion 611 and engages with the top wall 110 of the housing. In this way, the second light-transmitting cover 610 is used to close the second mounting hole 111, preventing light-blocking objects from entering the second mounting hole 111 and blocking light.

[0312] The lighting module 600 may also include a light-transmitting cover 620, which is located on the outside of the drawer cavity 102 and has a second sealing component 630 between it and the top wall 110 of the housing. While allowing light to enter the storage cavity 201 through the light-transmitting cover 620, the light-transmitting cover 620 and the second sealing component 630 seal the second mounting hole 111 to ensure the airtightness of the drawer cavity 102.

[0313] Continue to refer to Figure 18 The lighting module 600 may also include a lamp housing 640, which is connected to the top wall 110 of the housing. For example, the lamp housing 640 is snapped into the top wall 110 of the housing, making the installation of the lamp housing 640 simple.

[0314] In some possible implementations, a side wall 112 is formed on the top wall 110 of the shell, and a mounting groove is formed between the side wall 112 and the top wall 110 of the shell to mount the lighting module 600. Second slots 113 are respectively formed on both sides of the side wall 112 along its width direction, with the openings of the two second slots 113 facing each other. The second slots 113 extend along the depth direction of the drawer shell 100, and one end of the second slot 113 extending in the direction of extension is open.

[0315] The lamp housing 640 has a snap-fit ​​part 642 on both sides along the width direction. The snap-fit ​​part 642 slides into the second slot 113 through the opening at the end of the second slot 113, so that the snap-fit ​​part 642 snaps into the second slot 113, thereby realizing the snap-fit ​​between the lamp housing 640 and the top wall 110 of the housing.

[0316] The lamp housing 640 is installed by sliding snap-fit, which is simple and helps to improve assembly efficiency.

[0317] In some embodiments, the dimension of the second slot 113 along the height direction decreases along the sliding insertion direction, so that the lamp housing 640 gradually tightens along the sliding insertion direction, thereby restricting the position of the lamp housing 640 along the depth direction.

[0318] In other embodiments, the second slot 113 is provided with a limiting protrusion at one end opposite to the opening. The lamp housing 640 is restricted to the termination position of sliding into the depth direction by abutting against the limiting protrusion.

[0319] Continue to refer to Figure 18 A second receiving cavity 641 is formed between the lamp housing 640 and the light-transmitting cover plate 620. The lighting device may also include a lamp plate 650, which is located in the second receiving cavity 641 and is fixedly connected to the lamp housing 640.

[0320] For example, the lamp panel 650 and the lamp housing 640 are fixedly connected by screws to ensure the stability of the position between the lamp panel 650 and the lamp housing 640 and to prevent the lamp panel 650 from shifting due to the installation of the lamp housing 640.

[0321] In some embodiments of this application, the light-transmitting cover 620 can be bonded to the second sealing member 630, and the second sealing member 630 is bonded to the top wall 110 of the shell, thereby fixing the light-transmitting cover 620 to the top wall 110 of the shell, while ensuring the relative position between the second sealing member 630 and the top wall 110 of the shell, which helps to ensure the airtightness of the drawer cavity 102.

[0322] In other embodiments of this application, the lamp housing 640 and the second light-transmitting cover 610 abut against each other in an area other than the second mounting hole 111, so as to press the second light-transmitting cover 610 tightly against the top wall 110 of the housing. With this configuration, no additional fixing structure is required, and the light-transmitting cover 620 is fixed at the same time as the lamp housing 640 is installed, which helps to simplify the assembly steps and improve assembly efficiency.
