[0002] With the rapid development of smart homes, refrigerators, as essential storage and preservation appliances for families, are also gradually moving towards intelligentization. Traditional refrigerators can only achieve basic storage and refrigeration functions, which presents some problems in daily life. For example, when users go out to buy groceries, they cannot know the types and quantities of food left in the refrigerator, which can easily lead to duplicate purchases or omissions, increasing unnecessary expenses. In addition, when there are many items in the refrigerator, food located deep inside or hidden is easily forgotten, and after being stored for a long time, it will rot and produce odors.

Detailed Implementation

[0017] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0018] Example 1.

[0019] This embodiment provides a refrigerator with an image acquisition component installed in the refrigerator compartment, which can capture images of the front of the refrigerator compartment, such as when a user puts in or takes out food.

[0020] In this embodiment, Figure 1 In the diagram, the X-axis represents the width of the refrigerator, the Y-axis represents the depth of the refrigerator, and the Z-axis represents the height of the refrigerator.

[0021] like Figures 1 to 3 As shown, the refrigerator provided in this embodiment includes: a refrigerator compartment body 1 and a refrigerator compartment door 2. The refrigerator compartment body 1 has a refrigerator space inside. The refrigerator compartment door 2 is located at the front end of the refrigerator compartment body 1, and the refrigerator compartment door 2 can be opened or closed relative to the refrigerator compartment body 1. When the refrigerator compartment door 2 is closed, it can seal the refrigerator space.

[0022] by Figure 1 For example, the refrigerator compartment and freezer compartment are arranged from top to bottom. The refrigerator compartment door 2 can be a single door or a double door. Figure 1 The double doors shown.

[0023] A top surface light source 6 is installed at the top of the refrigeration space. The top surface light source 6 is parallel to the top wall of the refrigeration chamber body 1, and the rear end of the top surface light source 6 is installed on the refrigeration chamber body 1.

[0024] The image acquisition component 7 is located at the front end of the top surface light source 6, and the image acquisition component 7 faces the front side of the refrigeration space and acquires images diagonally downwards.

[0025] A processor is installed inside the refrigerator and electrically connected to the image acquisition component 7 to acquire captured images. The processor can process, analyze, and recognize the images, for example, by obtaining the type and quantity of food put in or taken out, and recording the time of food being put in or taken out in conjunction with the system time, thus showing the type and quantity of food currently in the refrigerator. It can also interact with the user terminal to send reminders to the user. Users can also view the food in the refrigerator compartment in real time through the image acquisition component 7 to know what food is in the refrigerator.

[0026] The technical solution provided in this embodiment has a refrigeration space inside the main body of the refrigerator compartment; a top surface light source is set at the top of the refrigeration space; the top surface light source is parallel to the top wall of the main body of the refrigerator compartment, and the rear end of the top surface light source is installed in the main body of the refrigerator compartment; an image acquisition component is set at the front end of the top surface light source, and the image acquisition component collects images at an angle downwards to know the type and quantity of food that the user puts in and takes out, and combines the system time analysis to obtain the remaining food in the refrigerator and the storage time, so as to realize intelligent management and control of the food in the refrigerator.

[0027] Based on the above technical solutions, this embodiment also provides examples of image acquisition components and their installation methods, such as... Figure 4 As shown, the top surface light source 6 includes: a surface light source bracket 61 and a surface light source assembly 62.

[0028] The surface light source bracket 61 includes a front crossbeam 611 and two side longitudinal beams 612. The front crossbeam 611 extends along the width of the refrigerator, and the two side longitudinal beams 612 are perpendicularly positioned at both ends of the front crossbeam 611. The front crossbeam 611 and the side longitudinal beams 612 form a U-shaped mounting area with one open end. The surface light source assembly 62 is positioned within this U-shaped mounting area, with its front end connected to the front crossbeam 611 and its two sides connected to the side longitudinal beams 612. The rear end of the surface light source assembly 62 is connected to the rear of the refrigerator compartment body 1.

[0029] The side longitudinal beam 612 has a U-shaped cross-section and is sandwiched between the upper and lower surfaces of the side of the surface light source assembly 62. The rear edge of the front cross beam 611 is also U-shaped and is sandwiched between the upper and lower surfaces of the front side of the surface light source assembly 62. The surface light source assembly 62 can be a light source assembly commonly used in the art, with a plate-like structure, and its size can be set according to the size of the refrigeration space.

[0030] The image acquisition component 7 is located in the middle of the front crossbeam 611. Specifically, as follows... Figure 5 As shown, a window 613 is provided in the middle of the front crossbeam 611. The image acquisition component 7 is mounted on the upper surface of the front crossbeam 611 and passes through the window 613. The front crossbeam 611 serves to fix and support the image acquisition component 7.

[0031] For image acquisition component 7, it can be implemented in the following way: such as Figures 6 to 8 As shown, the image acquisition component 7 includes: a lower cover 71, an image acquisition plate 72, a sealing ring 73, and an upper cover 74.

[0032] The lower cover 71 has a receiving groove, and the bottom wall of the receiving groove has a through hole. The image acquisition board 72 is embedded in the receiving groove 71, and the lens in the image acquisition board 72 is aligned with the through hole in the bottom wall of the receiving groove so that the lens can pass through the through hole to acquire images.

[0033] The upper cover 74 is connected to the lower cover 71, enclosing the image acquisition board 72 within the receiving groove. The sealing ring 73 is disposed at the mating point between the upper cover 74 and the lower cover 71 to seal the gap between them.

[0034] Mounting holes for threaded fasteners to pass through are provided at the top corners of the upper cover 74, sealing ring 73, and lower cover 71, and the upper cover 74, sealing ring 73, and lower cover 71 are connected together by threaded fasteners.

[0035] The lower cover 71 is equipped with a first clamping member and a second clamping member, which are respectively located at both ends of the image acquisition plate 72 to clamp the image acquisition plate 72 into the receiving groove. The first clamping member is a fixed member and cannot undergo elastic deformation. The second clamping member is a movable member that can undergo elastic deformation under external force and return to its original shape when the external force is removed.

[0036] During the assembly process, one end of the image acquisition plate 72 is first inserted under the first clamping member, and then the other end of the image acquisition plate 72 is pressed down. During the contact with the second clamping member, a pushing force is applied to the second clamping member to deform it. The image acquisition plate 72 continues to be pressed down to the bottom of the second clamping member. After the pushing force on the second clamping member disappears, the second clamping member returns to its original shape and clamps the image acquisition plate 72.

[0037] The outer side wall of the lower cover 71 extends outward to form a mounting ear 75. The mounting ear 75 has a mounting hole for threaded fasteners to pass through, and the mounting ear 75 is connected to the upper surface of the front crossbeam 611 by the threaded fasteners.

[0038] Furthermore, the mounting ear 75 and the bottom surface of the lower cover 71 are at a preset angle, and the distance between the rear end of the mounting ear 75 and the bottom surface of the lower cover 71 is less than the distance between the front end of the mounting ear 75 and the bottom surface of the lower cover 71. The mounting ear 75 is installed parallel to the front crossbeam 611, so that there is a certain angle between the lower cover 71 and the front crossbeam 611, so that the lens of the image acquisition board is shooting at an angle downwards, which can meet the user's viewing angle when putting in or taking out food.

[0039] Based on the above technical solutions, such as Figure 9 and Figure 10 As shown, an inner liner 11 is installed inside the main body 1 of the refrigerator compartment, forming a refrigerator space. A cable hole is provided in the middle of the top wall of the inner liner 11, and the connecting cable 76 of the image acquisition component 7 passes upward through the cable hole in the top wall of the inner liner and runs in the space between the top wall of the inner liner and the main body 1 of the refrigerator compartment.

[0040] A door hinge mounting hole 12 is provided at one end of the top wall of the refrigerator compartment body 1 for installing a pivot connector. The refrigerator compartment door 2 is rotatably connected to the refrigerator compartment body 1 via the pivot connector. The connecting cable 76 of the image acquisition component 7 passes through the door hinge mounting hole 12 and connects to the refrigerator control panel. A hinge fixing cover 13 is provided on the upper surface of the refrigerator compartment body 1 to close the door hinge mounting hole 12 and also to fix the connecting cable 76 at this position.

[0041] The above solution utilizes the existing door hinge mounting holes on the main body of the cold storage compartment to achieve wire threading, eliminating the need for additional drilling. This reduces manufacturing costs and eliminates the need to modify the mold structure or install additional embedded parts. Furthermore, it reduces the process of injecting glue to plug the holes, further lowering the risk of cold leakage due to poor sealing.

[0042] Based on the above solutions, such as Figure 11 and Figure 12 As shown, a refrigeration hood 14 is installed at the rear of the main body 1 of the refrigerator compartment. An evaporator, a refrigeration fan, and other components are installed at the rear end of the refrigeration hood 14. A connecting plate 15 is installed at the top of the refrigeration hood 14, and the connecting plate 15 is positioned at the top of the refrigeration space, parallel to the top wall of the main body 1 of the refrigerator compartment. The lower surface of the rear end of the connecting plate 15 extends downward to form a slot 16, and the rear end of the top surface light source 6 is installed within the slot 16.

[0043] A decorative panel 63 is also provided below the front crossbeam 611 to cover the front crossbeam 611. The decorative panel 611 also has through holes so that the lens in the image acquisition assembly can acquire images through the through holes.

[0044] Example 2.

[0045] Based on the above embodiments, this embodiment also provides a lighting strip on the upper rear side of the main body of the refrigerator compartment, which can serve as an ambient light to supplement brightness and enhance visual appeal, while also reducing the space occupied by the refrigerator compartment.

[0046] like Figures 12 to 16 As shown, the refrigeration hood 14 covers the rear of the refrigeration space, extending from the top to the bottom of the refrigeration space. A glass cover 17 is also provided at the rear of the refrigeration space. The height of the glass cover 17 is lower than the top of the refrigeration hood 14. A lighting fixture mounting groove is formed between the refrigeration hood 16 and the glass cover 17. A top lighting fixture (i.e., a lighting strip 8) is installed in the mounting groove and emits light towards the refrigeration space.

[0047] One embodiment is as follows: a glass cover 17 is disposed on the front side of the upper part of the refrigerator hood 14. The refrigerator compartment is divided into a large refrigerator compartment and a variable temperature zone from top to bottom. Typically, the size of the glass cover 17 matches the size and position of the large refrigerator compartment. A certain distance is left between the top of the glass cover 17 and the top of the refrigerator compartment, providing vertical light transmission space. A certain distance is also left between the top of the glass cover 17 and the refrigerator hood 14, providing installation space in the depth direction of the refrigerator.

[0048] The lighting strip 8 extends along the width of the refrigerator and is installed in the installation space between the glass cover 17 and the refrigerator hood 14. The light-emitting side of the lighting strip 8 faces the front of the refrigerator space, and the light emitted by the lighting strip 8 shines from the light-transmitting space into the refrigerator space.

[0049] The lighting strip 8 can be single-color or multi-color; it can be a single-color constant light, a breathing light that cycles on, or a multi-color light that cycles on; it can also be designed with changing patterns, such as shooting stars or scrolling patterns; and it can also be customized to display patterns to decorate the refrigerator's appearance and enhance its aesthetics.

[0050] In the above solution, the lighting strip 8 is much smaller than that of existing solutions in the field, occupying only a small portion of the space. It is located above the rear side of the refrigerator compartment, which can enhance the atmosphere and improve the appearance. On the other hand, it can reduce the volume occupied by the refrigerator compartment. It can also reduce heat generation, without affecting the cooling effect of the refrigerator compartment, and reduce the energy consumption of the refrigerator.

[0051] Traditional refrigerators typically have only one light in the refrigerator compartment, which illuminates when the door is opened to allow users to see the items inside. Some manufacturers also add ambient lighting to the refrigerator compartment, usually a surface-emitting light source that covers the entire rear of the compartment and is secured with bolts. These ambient lights occupy a significant amount of space in the refrigerator compartment, affecting the refrigerator's volume; furthermore, they generate heat, increasing energy consumption and negatively impacting food preservation.

[0052] The lighting strip provided in this embodiment extends along the width of the refrigerator and is installed in the space between the glass cover and the refrigerator hood. The light-emitting side of the lighting strip faces the front of the refrigerator compartment. The light emitted by the lighting strip shines from the light-transmitting space into the refrigerator compartment. This not only enhances the lighting atmosphere in the refrigerator compartment but also reduces the space occupied and does not affect the volume. When the size of the lighting strip is reduced, the power decreases, reducing heat generation and thus not affecting the cooling effect of the refrigerator compartment, thereby reducing the refrigerator's energy consumption.

[0053] Based on the above technical solution, this embodiment illustrates the installation method of the lighting strip 8: the material and structure of the refrigeration hood 14 can be implemented with reference to existing technologies. This embodiment makes adaptive improvements to the refrigeration hood 14 to meet the installation requirements of the lighting strip 8.

[0054] Specifically, the upper part of the refrigeration hood 14 includes: a first back panel 141, a second back panel 142, a third back panel 143, and a support plate 144. The first back panel 141, the second back panel 142, the third back panel 143, and the support plate 144 can be formed by multiple bending. The first back panel 141, the second back panel 142, and the third back panel 143 are all parallel to the rear wall of the main body 1 of the refrigeration compartment.

[0055] The distance between the first back panel 141 and the rear wall of the refrigerator compartment body 1 is greater than the distance between the third back panel 143 and the rear wall of the refrigerator compartment body 1, which means that the first back panel 141 is positioned closer to the front. The distance between the third back panel 143 and the first back panel 141 serves as the installation space. The lighting strip 8 is located within the installation space between the first back panel 141 and the third back panel 143.

[0056] The distance between the first back panel 141 and the rear wall of the refrigerator compartment body 1 is greater than the distance between the second back panel 142 and the rear wall of the refrigerator compartment body 1, which means that the first back panel 141 is positioned closer to the front. The distance between the second back panel 142 and the first back panel 141 also serves as part of the installation space. The second back panel 142 is higher than the first back panel 141, and the bottom end of the second back panel 142 can be at the same height as the top end of the first back panel 141.

[0057] The support plate 144 extends along the depth of the refrigerator. The front end of the support plate 144 connects to the top of the first back panel 141, and the rear end of the support plate 144 connects to the bottom of the second back panel 142. The third back panel 143 is disposed above the second back panel 142. The top of the glass cover 17 is higher than the top of the first back panel 141, and the bottom of the lighting strip 8 is located in the space enclosed by the support plate 144, the second back panel 142, and the glass cover 17.

[0058] Based on the above technical solution, the lighting strip 8 can adopt a long strip-shaped light source commonly used in the art. For example, the lighting strip 8 in this embodiment includes: a lighting slot 81 and a light-emitting module 82. The lighting slot 81 includes a slot bottom plate, a slot front plate, and a slot back plate, with the slot front plate and back plate respectively disposed on the front and rear sides of the slot bottom plate; the slot bottom plate, slot front plate, and slot back plate form a slot for inserting the light-emitting module 82.

[0059] Furthermore, the distance between the second back panel 142 and the rear wall of the refrigerator compartment body 1 is less than the distance between the third back panel 143 and the rear wall of the refrigerator compartment body 1. This means that the second back panel 142 is further back than the third back panel 143, and therefore the distance between the second back panel 142 and the glass cover 17 is larger, which is used to accommodate the lighting slot 81.

[0060] The top of the glass cover 17 is flush with the top of the second back panel 142. The glass cover 17 can cover the lighting slot 81 so that the lighting slot 81 is not visible to the user after opening the refrigerator door, thus improving aesthetics. The light-emitting module 82 shines from above the glass cover 17.

[0061] One implementation is as follows: In the width direction of the refrigerator, the two ends of the support plate 144 are respectively provided with fixing blocks and buckles for limiting the lighting strip 8, so as to limit the lighting strip 8 and prevent it from falling out.

[0062] If a fixed stop is provided at the left end of the support plate 144 and a buckle is provided at the right end, the lighting strip 8 will be inserted from right to left into the installation space between the refrigeration hood 14 and the glass cover plate 17 until the left end reaches the fixed stop and is limited, and the right end is clamped by the buckle.

[0063] If a fixed stop is provided at the right end of the support plate 144 and a buckle is provided at the left end, the lighting strip 8 will be inserted from left to right into the installation space between the refrigeration hood 14 and the glass cover plate 17 until the right end reaches the fixed stop and is limited, and the left end is clamped by the buckle.

[0064] In this embodiment, the second scheme described above is adopted, such as... Figure 13 and Figure 14 As shown, a fixing block 181 is provided at the right end of the support plate 144 to limit the lighting strip 8. Figure 13 This is a front view of the refrigerator. Figure 13 The glass cover plate 17 was not shown in the image.

[0065] Figure 14 From the rear view of the refrigerator, a clip 182 is provided at the left end of the support plate 144. The lighting strip 8 is inserted from left to right into the installation space between the refrigerator hood 14 and the glass cover 17. After installation, the clip 182 locks the lighting strip 8 in place.

[0066] The latch 182 includes a latch body and a latch tongue. The latch body is located at the end of the support plate 144 and extends outward along the width direction of the frost; the upper surface of the latch body is flush with the upper surface of the support plate 144; the latch tongue protrudes from the upper surface of the latch body away from the end of the support plate. During the installation of the lighting strip 8, downward pressure is applied to the latch tongue, causing the latch 182 to bend downward. After the lighting strip 8 has completely passed the latch tongue, the pressure is no longer applied to the latch tongue, and the latch 182 springs back to its original shape, while the latch tongue moves upward to the left end of the lighting strip 8, limiting the lighting strip 8.

[0067] Based on the above technical solution, a through locking hole 145 is opened on the second back plate 142. The locking screw is inserted into the locking hole 145 from the rear side and presses against the lighting strip 8 to further limit and fix the lighting strip 8.

[0068] Specifically, the locking hole 145 is provided corresponding to the slot back plate in the lighting slot 81 so that the locking screw is inserted into the locking hole 145 from the rear and presses against the slot back plate.

[0069] One embodiment is as follows: the rear surface of the back plate is provided with a locking groove 83 extending along the width direction of the refrigerator, the locking hole is provided corresponding to the locking groove 83, and the locking screw is inserted into the locking groove 83 to tighten the back plate.

[0071] Based on the above technical solution, the refrigerator provided in this embodiment also has a light installed on the outer surface of the refrigerator door, which can provide brightness to the surrounding space at night.

[0072] like Figure 1 , Figures 17 to 31 As shown, a door handle 3 is provided at the bottom of the refrigerator door 2. The bottom or side of the door handle 3 is recessed to form a latch. The user can open the refrigerator door 2 by inserting their fingers into the latch and pulling it outward. The front end of the door handle 3 has a light strip mounting groove, into which the door light strip 5 is embedded. The door light cover 4 is placed on the outside of the light strip mounting groove and is detachably connected to the door handle 3.

[0073] The door light strip 5 can use a lighting module commonly used in existing technologies to emit light when powered on. The door light cover 4 can protect the door light strip 5 and diffuse the light emitted by the door light strip 5, making the light soft and evenly distributed.

[0074] In dimly lit environments, the door light strip 5 illuminates with a brightness equivalent to a nightlight, allowing users to see surrounding objects clearly for easier operation. It also allows the eyes to adjust to the light in advance, preventing glare from the refrigerator door when the light inside is opened, thus improving comfort.

[0075] Furthermore, the door light strip 5 can be single-color or multi-color; it can be a single color that is always on, or a breathing light that cycles on, or multiple lights that cycle on; it can also be designed with changing patterns, such as shooting stars, scrolling patterns, etc.; and it can also be customized to display patterns to embellish the appearance of the refrigerator and enhance its aesthetics.

[0076] Traditional refrigerators typically only have one light in the refrigerator compartment, which turns on when the door is opened to allow users to see the items inside. However, when users take items out of the refrigerator at night, the bright light from inside can easily cause glare and be blinding.

[0077] The technical solution provided in this embodiment illuminates the surrounding environment through the door light strip on the door handle, allowing users to see objects around them without turning on the indoor headlights, making it convenient for users to retrieve items at night; and it also allows users' eyes to adapt to the light in advance, so that they will not feel glare when opening the refrigerator door, thus improving comfort.

[0078] This embodiment provides an example, such as Figure 1 The refrigerator shown has a refrigerator compartment and a freezer compartment arranged from top to bottom. The light is located on the bottom door handle of the refrigerator compartment 2, which is basically in the middle of the refrigerator, giving it good symmetry and a more aesthetically pleasing appearance.

[0079] Refrigerator door 2 can be a single door or a double door. Figure 1 The double door shown. If it is a double door, the two door panels are opposite doors. The side of the two door panels that are far apart from each other is hinged to the main body 1 of the refrigerator compartment. Lighting lights are installed on both door panels, specifically the door handles 3, door light covers 4 and door light strips 5 mentioned above.

[0080] Specifically, the opening of the light strip mounting groove on the door handle 3 faces the front of the refrigerator, the door light strip 5 is embedded in the light strip mounting groove, and the door light cover 4 is set on the front of the refrigerator door 2, covering the door light strip 5.

[0081] The surface of the door light cover 4 is flush with the surface of the refrigerator door 2, improving the uniformity and aesthetics of the refrigerator surface. The dimensions of the door light cover 4 are the same as those of the refrigerator door 2 along the width of the refrigerator.

[0082] Based on the above technical solution, this embodiment provides a specific description of the lighting solution: The door handle 3 extends along the width of the refrigerator and is installed to the refrigerator compartment body 1. The shape and structure of the door handle 3 can be adaptively designed according to the shape of the refrigerator compartment body 1. The door handle 3 can be fixed to the refrigerator compartment body 1 by snap-fit ​​or screw connection.

[0083] The bottom of the door handle 3 is provided with a first limiting part 31 for supporting the door light strip 5. The end of the door handle 3 is provided with a second limiting part 32 for limiting the door light strip 5. The second limiting part 32 is provided with a triangular locking buckle 33, which can limit the door light strip 5 in the depth direction.

[0084] In addition, the other end of the door handle 3 is provided with a third limiting part 36 for limiting the door light strip 5. The third limiting part 36 can support the bottom of the door light strip 5 and limit the door light strip 5 along the depth direction.

[0085] During installation, the right end of the door light strip 5 is placed into the light strip mounting groove, and then a pushing force is applied to the left end of the door light strip 5 along the depth direction to push the door light strip 5 into the light strip mounting groove. After the door light strip 5 passes the locking buckle 33, the right-angled side of the locking buckle 33 abuts against the outer side of the door light strip 5 to limit the door nail strip 5 and lock the door light strip 5 into the light strip mounting groove.

[0086] The door handle 3 has a door light wiring hole 34 for the electrical wire of the door light strip 5 to pass through. After passing through the door light wiring hole 34, the electrical wire is connected to the refrigerator's power supply, which then supplies power to the door light strip 5. Alternatively, the electrical wire can also be connected to a controller in the refrigerator, which can adjust the lighting mode or pattern of the door light strip 5.

[0087] Based on the above technical solution, a first hook 35 is provided on the outer side of the door handle 3. Correspondingly, a second hook 41 is provided on the inner side of the door lamp cover 4. The door lamp cover 4 is engaged with the first hook 35 through the second hook 41, thereby limiting the door lamp cover 4 in a first direction and a second direction. The first direction is the same as the width direction of the refrigerator, and the second direction is the same as the depth direction of the refrigerator.

[0088] One embodiment is as follows: the first hook 35 has an L-shaped structure and faces the opposite direction to the assembly direction of the door lamp cover 4. The second hook 41 has an L-shaped structure and faces the assembly direction of the door lamp cover; the second hook 41 can be inserted into the first hook 35 along the assembly direction of the door lamp cover.

[0089] like Figure 26 and Figure 27 As shown, the door light cover 4 moves along the Y direction and is installed towards the door handle 3, and is installed in place as shown. Figure 28 and Figure 29 As shown. Then move the door light cover 4 along the X direction so that the second hook 41 is inserted into the first hook 35, thus completing the installation and locking of the door light cover 4.

[0090] During disassembly, first move the door light cover 4 in the opposite direction of the X direction to separate the second hook 41 from the first hook 35, and then remove the door light cover 4 in the opposite direction of the Y direction. The disassembly and assembly process is simple and quick.

[0091] Furthermore, the end of the door lamp cover 4 is also provided with a fourth limiting part 42 extending along the assembly direction of the door lamp cover 4, which is used to insert the door handle 3 during the installation process to further limit the door lamp cover 4.

[0092] One embodiment is as follows: the door handle 3 is provided with two rows of first hooks 35, the two rows of first hooks 35 being located above and below the light strip mounting groove respectively, and each row including multiple first hooks 35 arranged at intervals. Correspondingly, the door light cover 4 is provided with two rows of second hooks 41, the positions of the second hooks 41 being corresponding to the first hooks 35.

[0093] The two ends of the door lampshade 4 are bent inward to block the light from both sides and prevent light leakage from the sides.

[0094] Example 4.

[0095] Based on the above technical solutions, this embodiment also provides a method for dynamic monitoring of food ingredients inside a refrigerator based on image recognition.

[0096] like Figure 32 As shown, the following embodiments use the aforementioned controller as the execution subject to specifically illustrate the dynamic monitoring of food ingredients in a refrigerator control system. The image recognition-based dynamic monitoring method for food ingredients inside a refrigerator provided in this application includes the following steps 401-403: Step 401: In response to the refrigerator door opening signal, the top surface light source starts to emit light, the image acquisition component acquires the spatial image of the refrigerator interior space in real time, and sends the spatial image to the control component; Step 402: The control component identifies the spatial images received in real time based on a pre-configured target recognition model to obtain the identified objects in each spatial image; The objects to be identified include at least hands and food ingredients. The target recognition model can be the YOLO model or other types of recognition models. This application does not impose specific limitations and can be flexibly selected according to the actual situation.

[0097] Step 403: Determine the real-time position of each identified object in the spatial image in the preset coordinate system; The preset coordinate system can be the pixel coordinate system in the image or the spatial coordinate system of the refrigerator, or other coordinate systems. This application embodiment does not make specific limitations and can be flexibly selected or set according to the actual situation, as long as it can realize the unified mapping of the position of the image and the refrigerator entity.

[0098] Step 404: Determine the state changes of the food in the refrigerator's interior space based on the real-time positions of each identified object in multiple consecutive frames of the spatial images.

[0099] The above solution acquires spatial images of the refrigerator's interior space in real time using an image acquisition component. Based on a pre-configured target recognition model, it identifies the real-time received spatial images to obtain the objects to be identified in each spatial image. After determining the real-time position of each object in each spatial image in a preset coordinate system, it determines the state changes of the food in the refrigerator's interior space based on the real-time positions of each object in multiple consecutive frames of spatial images. This avoids installing too many sensors on the refrigerator and determines the position changes of the food through image recognition, thereby achieving dynamic monitoring of the food inside the refrigerator.

[0100] In an optional embodiment of this application, step 404 above, determining the state changes of the food in the refrigerator's interior space based on the real-time positions of each identified object in multiple consecutive frames of the spatial images, includes at least the following three cases: In the first case, if there is an intersection between the hand and the first food ingredient in the Mth frame spatial image, and the first food ingredient is not present in the recognition object of the Nth frame spatial image, then the state change of the food ingredient in the refrigerator's interior space is to take out the first food ingredient; where M and N are both positive integers greater than 1, and N > M. In the second case, if the first food ingredient is not present in the spatial image of the Mth frame, and there is an intersection between the hand and the first food ingredient in the recognition object of the spatial image of the Nth frame, then the state change of the food ingredient in the refrigerator's interior space is to take in the first food ingredient. In the third scenario, if the hand and the first food ingredient intersect in the first storage area in the Mth frame spatial image, and the hand and the first food ingredient intersect in the second storage area in the Nth frame spatial image, then the state change of the food ingredient in the refrigerator's interior space is to move the first food ingredient from the first storage area to the second storage area.

[0101] If the detection borders of the food and the hand intersect, it is determined that the food is in the hand; if the border of the hand or the food is within a certain area border, it is determined that the food is in that area; if it is not within any area border, it is determined that the food is outside the refrigerator; if the hand moves from outside the refrigerator to a certain position inside the refrigerator and stays in that position for more than, for example, 300 milliseconds, it is determined that the food is being taken in, and the food previously held in the hand is recorded; if the hand moves from a certain position inside the refrigerator to outside the refrigerator, it is determined that the food is in the dark, and the food currently held in the hand is recorded.

[0102] The above-mentioned scheme can accurately determine the state changes of food in the refrigerator space by checking whether there is an intersection between the hand and the first food in each frame of spatial image, and whether there is food in the recognition object of the spatial image. The method is simple and fast. Moreover, the embodiment of this application makes the judgment by using multiple consecutive frames of the spatial image, which can avoid frame drops caused by failure of image acquisition components or communication networks, and the state judgment is more accurate.

[0103] In one optional embodiment of this application, step 404 above, determining the state changes of the food in the refrigerator's interior space based on the real-time positions of each identified object in multiple consecutive frames of the spatial images, includes the following three cases: In the first case, if the hand and the first food ingredient have an intersection in the Mth frame spatial image for more than a preset time, and the first food ingredient is not found in the recognition object of the Nth frame spatial image, then the state change of the food ingredient in the refrigerator's interior space is to take out the first food ingredient; where M and N are both positive integers greater than 1, and N > M. In the second case, if the first food ingredient is not present in the spatial image of the Mth frame, and the hand and the first food ingredient have an intersection in the recognition object of the spatial image of the Nth frame for more than a preset time, then the state change of the food ingredient in the refrigerator's interior space is to take in the first food ingredient. In the third scenario, if the hand and the first food ingredient in the Mth frame spatial image have an intersection in the first storage area for more than a preset time, and the hand and the first food ingredient in the Nth frame spatial image have an intersection in the second storage area for more than a preset time, then the state change of the food ingredient in the refrigerator's interior space is to move the first food ingredient from the first storage area to the second storage area.

[0104] The preset duration can be, for example, 300 milliseconds. By setting this preset duration and filtering out false judgments through a time threshold, the accuracy and reliability of monitoring can be greatly improved in this embodiment of the application.

[0105] In one optional embodiment of this application, the refrigerator interior space includes multiple storage areas, each area having at least one storage drawer; the method further includes the following steps: The storage drawer containing the ingredients in each identified object is determined based on the real-time position of each identified object in the preset coordinate system in each spatial image.

[0106] The storage drawers include, but are not limited to, fruit and vegetable drawers, temperature-controlled drawers, and fresh-keeping drawers. In this embodiment, the storage drawers where the ingredients of each identified object are located are determined based on the real-time position of each identified object in the preset coordinate system in the spatial image. This allows for easy determination of the real-time storage position of each ingredient before and after a state change, as well as during the state change process. This facilitates subsequent updates to the ingredient list in each drawer and enables users to achieve more precise dynamic monitoring of ingredients.

[0107] In one optional embodiment of this application, the control component is configured with a food ingredient database; correspondingly, after step 402 above, where the control component identifies the spatial images received in real time based on a pre-configured target recognition model to obtain the objects to be identified in each spatial image, the method includes: Each identified object is compared with each ingredient in the ingredient database to determine the ingredient category of each identified object; If the currently identified object does not exist in the food database, the area where the currently identified object is located in the spatial image is sent to the service terminal; Receive the identification result sent by the service terminal, and determine the food category of the current identification object based on the identification result.

[0108] Configuring an ingredient database can improve the speed of ingredient identification, enabling local recognition even in poor or no network conditions. Through collaboration between the local machine and the service terminal, network resource requirements can be greatly reduced and ingredient recognition efficiency can be significantly improved. At the same time, the ingredient database can be open-sourced to users, allowing them to maintain and update their local ingredient database for user convenience.

[0109] In an optional embodiment of this application, after step 404 above, which involves determining the state changes of the food items in the refrigerator's interior space based on the real-time positions of each identified object in multiple consecutive frames of the spatial images, the method further includes the following steps: The changes in the state of the food in the refrigerator's interior space are converted into voice information and broadcast.

[0110] It allows users to determine changes in the state of ingredients from multiple dimensions, improving the dimensions and efficiency of human-computer interaction.

[0111] In an optional embodiment of this application, the above-described image recognition-based method for dynamic monitoring of food items inside a refrigerator further includes the following steps: Upload the status changes of the food in the refrigerator's interior space to the service terminal; and / or, The status changes of the food in the refrigerator's interior space are updated to a pre-built food list and displayed; wherein the food list is stored in the control component and / or the user's remote terminal.

[0112] By uploading changes in the status of food items inside the refrigerator to a service terminal or updating and displaying a pre-built food list, users can easily monitor changes in the food items inside the refrigerator in real time. This enables automated identification and recording of the food storage and retrieval process, eliminating the need for manual operation by the user, thus improving the level of intelligent refrigerator management and optimizing the user's food management experience.
