Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigerator. Background Technology

[0002] In existing refrigerators, the display control panel is typically embedded inside the refrigerator, requiring users to interact with the refrigerator by touching a membrane or glass cover on its surface. To select or adjust functions, users often need to press or touch the control panel's surface for extended periods. With frequent use, the fixing structure of the membrane or glass cover may bend or deform, especially when the control panel is subjected to excessive touching or pressing. Furthermore, the glass or membrane surface is highly susceptible to fingerprints, water stains, and other dirt, which not only affects the aesthetics of the control panel but may also interfere with user operation, reducing the user experience.

[0003] Therefore, in existing refrigerator designs, the lifespan of the display and control panel and the user experience are often affected by factors such as prolonged pressing and stains. A new solution is urgently needed to effectively avoid these problems and improve the functionality of the refrigerator and the user experience. Utility Model Content

[0004] The purpose of this invention is to at least solve the problem of malfunctions in existing refrigerators, such as the display control panel easily bending or deforming due to pressure. This purpose is achieved through the following technical solution:

[0005] This utility model proposes a refrigerator, comprising:

[0007] A partition is provided in the storage room, which divides the storage room into a first storage area and a second storage area. The second storage area is located below the first storage area, and the partition is provided with a light-transmitting area for light to pass through.

[0008] An imaging component is disposed in the second storage area, and the imaging component is configured to project a virtual control panel onto a preset area of ​​the first storage area through the light-transmitting area.

[0010] According to this invention, a refrigerator features a partition in the storage compartment with a light-transmitting area. An imaging component and a vision detection component are arranged in a second storage area. A virtual control panel is projected onto a preset area through the light-transmitting area, enabling a user-friendly human-computer interaction method without direct contact. Specifically, replacing the traditional physical display control panel with a virtual control panel eliminates the need for prolonged pressing or frequent touching of the control interface, effectively preventing bending and deformation of the control panel's fixed structure due to repeated pressing and significantly extending its lifespan. Furthermore, the virtual control panel eliminates the need for a physical surface, avoiding the accumulation of fingerprints, water stains, and other dirt, maintaining a clean and aesthetically pleasing control interface. This not only enhances the refrigerator's overall appearance but also ensures smooth and convenient user operation. Additionally, the partition divides the storage compartment into upper and lower sections, making efficient use of space. The imaging component and vision detection component are centrally located in the second storage area, ensuring a compact and orderly internal structure without compromising the storage function of the compartment.

[0011] In addition, the refrigerator according to this utility model may also have the following additional technical features:

[0020] In some embodiments of this utility model, the mounting box includes a support structure disposed on the inner wall of the mounting box. The support structure is fixedly connected to the imaging component and the visual detection component, respectively, and is used to fix the imaging component and the visual detection component.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0031] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms.

It should also be understood that additional or alternative steps may be used.

[0032] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0033] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0034] like Figures 1 to 4 As shown, according to an embodiment of the present invention, a refrigerator 100 is proposed. The refrigerator 100 includes a cabinet 10, a partition 20, an imaging component 30, and a vision detection component 40. The cabinet 10 defines a storage compartment 101. The partition 20 is parallel to the bottom surface of the cabinet 10 and disposed within the storage compartment 101, dividing the storage compartment 101 into a first storage area 1011 and a second storage area 1012. The second storage area 1012 is located below the first storage area 1011. The partition 20 has a light-transmitting area for allowing optical fibers to pass through. The imaging component 30 is disposed in the second storage area 1012 and is configured to project a virtual control panel 301 onto a preset area of ​​the first storage area 1011 through the light-transmitting area. The vision detection component 40 is disposed in the second storage area 1012 and is used to detect user operations on the virtual control panel 301.

[0035] According to this embodiment, the refrigerator 100, by providing a partition 20 in the storage compartment 101 and having a light-transmitting area on the partition 20, and arranging the imaging component 30 and the visual detection component 40 in the second storage area 1012, can project a virtual control panel 301 onto a preset area through the light-transmitting area, realizing a user-computer interaction method that does not require direct contact. Specifically, by using a virtual control panel 301 to replace the traditional physical display control panel, users do not need to press or frequently touch the control interface for a long time, thereby effectively preventing malfunctions such as bending and deformation of the display control panel's fixed structure due to repeated pressing, and significantly extending the service life of the display control panel. Furthermore, the virtual control panel 301 has no physical surface, avoiding the accumulation of fingerprints, water stains, and other stains, keeping the control interface clean and aesthetically pleasing, which not only improves the overall appearance of the refrigerator 100 but also ensures the smoothness and convenience of user operation. In addition, the partition 20 divides the storage compartment 101 into upper and lower parts, making reasonable use of the space layout. The imaging component 30 and the vision detection component 40 are centrally placed in the second storage area 1012, ensuring that the internal structure of the refrigerator 100 is compact and orderly, without affecting the storage function of the storage compartment 101.

[0036] It is important to note that Figures 1 to 4 The virtual control panel 301 is marked in the figure, but the virtual control panel 301 is not a physical structure. It is a light plane formed by light refraction. In order to show the position of the virtual control panel 301 in the refrigerator 100 and the relationship between the virtual control panel 301 and the imaging component 30, the virtual control panel 301, which is not a physical structure, is shown in the figure.

[0037] like Figure 4 As shown, in some embodiments, the imaging component 30 includes a display light source 31 and a negative refractive lens 32. The display light source 31 emits light towards the negative refractive lens 32, and the negative refractive lens 32 refracts the light and projects the virtual control panel 301 through the light-transmitting area onto a preset area. The appropriate combination of the negative refractive lens 32 and the display light source 31 can achieve high-quality virtual projection within a shorter optical path. Furthermore, the negative refractive properties can optimize the optical path, making the virtual control panel 301 closer to the user's line of sight or operating area, presenting a three-dimensional and easily recognizable virtual control panel 301, and providing the user with a more technologically advanced operating experience.

[0038] Specifically, the display light source 31 is located below the negative refractive lens 32 to ensure that the incident angle of the light is adapted to the working range of the negative refractive lens 32, thereby avoiding image distortion or energy loss.

[0039] Furthermore, the display light source 31 is a display panel, and this display panel is set at an angle to the partition plate 20, with the angle ranging from 45° to 60°. The negative refractive lens 32 is set parallel to the partition plate 20, so that the virtual control panel 301 and the display panel are mirror-symmetrical about the negative refractive lens 32 as the reference plane. The angle range of 45° to 60° takes into account factors such as imaging distance, light refraction path, and user viewing angle. On the one hand, it ensures smoother optical coordination between the display panel and the negative refractive lens 32, and on the other hand, it avoids distortion or energy loss caused by excessive imaging tilt or too close distance. If the angle is too small, the display panel and the partition plate 20 are basically parallel, that is, the distance between the display panel and the partition plate 20 is too large, resulting in an excessively long projection light path, which is easily limited by the internal space of the refrigerator 100 and the light source intensity, making it difficult to obtain a clear virtual control panel 301. If the angle is too large, the display panel and the partition 20 will be excessively tilted, which may cause a large displacement of the imaging area, or make it difficult for the user to see the virtual control panel 301 intuitively at a normal door opening angle. Keeping the negative refractive lens 32 parallel to the partition 20 allows the light emitted by the display panel to maintain a relatively stable incident angle and exit angle during the refraction process, thereby accurately projecting the virtual control panel 301 onto the expected preset area.

[0040] Specifically, with an angle of 45°, the angle between the display panel and the partition 20 is relatively small, resulting in a shorter refraction distance required for the projected light inside the refrigerator 100. This helps reduce the space occupied by the imaging channel, making the structure more compact. However, due to the smaller angle, the virtual control panel 301 may be positioned closer to the partition 20, which may require users to adjust their viewing angle for a clearer view, potentially slightly reducing user comfort.

[0041] Specifically, the included angle is 55°, which provides a larger tilt surface compared to 45°. This allows for a better balance between the optical path length, imaging distance, and user line of sight, ensuring projection clarity and operability. However, the increased included angle means that the display panel may occupy more space relative to the partition plate 20, requiring a larger optical path channel and installation position to be reserved in the storage room 101 or the second storage area 1012.

[0042] Specifically, the angle is 60°. This 60° angle allows the projection surface to have a greater upward angle relative to the user's line of sight. For users of most heights, this means they can directly observe and operate the virtual control panel 301 without bending over or turning to the side, resulting in a high level of interactive comfort. However, the longer imaging path means that the display panel may require higher brightness or light source power to ensure the projection effect and overcome energy attenuation or light loss at a larger refraction angle.

[0043] Understandably, when light passes through the negative refractive lens 32, the angle of incidence and the angle of incidence have a certain symmetry. This means that if we place a display panel on one side of the lens, the image seen on the other side will be mirror-symmetrical to the display panel on the reference plane. Compared to a regular positive refractive lens that simply focuses or disperses light, negative refraction fundamentally changes the direction of light propagation at the medium interface, thus creating a mirror image, as if it were "the other side of the lens," under certain conditions. That is, the virtual control panel 301 and the display panel are mirror-symmetrical about the negative refractive lens 32 as the reference plane.

[0044] Furthermore, the negative refractive lens 32 can be attached to the bottom of the partition plate 20 and configured in conjunction with the light-transmitting area, meaning the negative refractive lens 32 projects onto the partition plate 20, and this projection is located within the light-transmitting area. The negative refractive lens 32 is attached to the bottom of the partition plate 20 (i.e., the side facing the second storage area 1012), ensuring its center is aligned with the light-transmitting area on the partition plate 20. In this way, the light emitted from the display light source 31 can pass through the light-transmitting area and, under the anomalous refraction of the lens, form a clear virtual control panel 301 in a predetermined area above the partition plate 20. Additionally, the fixing method can use adhesives (such as optical adhesive, structural adhesive, etc.) for installation, ensuring a tight fit between the negative refractive lens 32 and the partition plate 20. Furthermore, to ensure cleanliness and facilitate future maintenance, a detachable or replaceable module can be reserved at the bottom of the partition plate 20 for easy cleaning, repair, or replacement by users or after-sales personnel. For example, the partition plate 20 has symmetrically arranged L-shaped slots below it, and the negative refractive lens 32 can be inserted into the L-shaped slots, making it convenient for users or after-sales personnel to clean, repair or replace it.

[0045] Furthermore, the negative refractive lens 32 can also be integrally integrated with the partition plate 20, meaning the negative refractive lens 32 is positioned within the light-transmitting area of ​​the partition plate 20, forming an integral structure with it. By integrating the optical microstructure of the negative refractive lens 32 into the light-transmitting area of ​​the partition plate 20, this area not only has light transmission capabilities but also performs anomalous refraction of light, thereby creating the "mirror symmetry" effect required by the virtual control panel 301. This method can be achieved by pre-embedding a structural layer or film layer with negative refractive properties into the material or local stacking of the partition plate 20 through processes such as injection molding, hot pressing, and micro / nano fabrication to form the negative refractive lens 32. Since the negative refractive lens 32 and the partition plate 20 are integrally integrated, the additional steps of optical component bonding, positioning, and sealing are eliminated, simplifying the assembly process and reducing the possibility of errors during assembly. It avoids misalignment or detachment caused by adhesives or snap-fit ​​connections, reduces the risk of potential mechanical fatigue or sealing failure, and significantly improves reliability. Meanwhile, the integrated design eliminates the air layer, adhesive layer, and other interfaces between the separator 20 and the negative refractive lens 32, reducing multiple reflections and refractions of light between the interfaces, thereby reducing optical loss. Light passes through the separator 20 with higher transmittance and directly enters the negative refractive structure, enabling more accurate guidance and control of the light path, thus improving the imaging brightness and clarity of the virtual control panel 301.

[0046] In some embodiments, the visual detection component 40 is a visual sensor, and the sensing area of ​​the visual sensor is arranged parallel to the virtual control panel 301. In this solution, the sensing area of ​​the visual sensor (e.g., the imaging plane of a camera or the detection plane of a TOF sensor) is arranged parallel to the virtual control panel 301, which means that when the user performs gestures or taps on the virtual panel seen "floating" or "above the partition," the visual sensor can capture changes in the position of the hand or fingertips with minimal parallax.

[0047] Furthermore, by reasonably adjusting the distance and angle between the visual sensor and the negative refractive lens, the optical path of the negative refractive lens is made relatively independent from the field of view of the visual sensor, thus avoiding cross-interference.

[0048] By aligning the sensing plane with the geometry of the displayed virtual interface, detection errors and algorithm complexity can be significantly reduced, and "distortion" or "blind spots" in visual detection when the user's hand is tilted at an excessive angle can be avoided. The visual sensor is arranged in the second storage area 1012 on the same side as the display light source 31, with the sensing plane facing the imaging area of ​​the virtual control panel 301. When the sensing plane is parallel to the virtual interface, the effective field of view of the visual sensor can be fully utilized, and a more stable detection resolution can be obtained in both the horizontal and vertical directions. For depth cameras, parallel arrangement also helps to improve the accuracy of depth measurement and is less prone to calculation errors caused by local shadows or excessive tilt. In addition, when the user's finger performs clicks, swipes, or other operations on the virtual control panel 301, the visual sensor acquires the image (or depth information) of the designated area, and the software algorithm maps it to the coordinate system of the virtual panel to determine the touch position, operation type, etc. If there is a significant tilt between the sensing plane and the virtual control panel 301, the algorithm requires cumbersome perspective correction. This solution makes the two parallel, which reduces the amount of correction calculation and enhances the real-time performance and accuracy of recognition.

[0049] As we can understand, a TOF (Time-of-Flight) sensor is a sensor that measures the distance between an object and a sensor by utilizing the time it takes for light to travel through space ("time of flight"). First, the TOF sensor uses a built-in or external light source (commonly infrared or near-infrared LEDs or lasers) to send light pulses towards the scene or target object. When the light encounters the surface of the target object, it is reflected or scattered. A receiver within the sensor (such as a specially designed photodetector) collects the returned light signal. By comparing the time difference between light emission and reception, the phase difference of the light pulses, or the intensity changes of multiple pulses, the TOF sensor can obtain the distance (or depth information) between the object and the sensor. TOF sensors can provide relatively high-precision distance data, are not easily affected by background light, and are suitable for applications such as gesture recognition.

[0050] In some embodiments, the refrigerator 100 also includes a voice sensor located within the storage compartment 101. The voice sensor is used to receive user voice commands. The voice sensor can be positioned inside the storage compartment 101 (e.g., on the top, side wall, or below the partition 20), and a voice sensor (such as a microphone module) can be installed to directly capture the user's voice commands. Since the refrigerator door is frequently opened and closed during normal use, the sensor location should be as far away as possible from the effects of condensation, frost, or spilled liquids from food, while maintaining good sound reception. The voice sensor needs to operate in the low-temperature environment inside the storage compartment 101; a waterproof and moisture-proof membrane or seal can be added externally to ensure the stability and durability of the microphone and circuitry. Furthermore, since there may be noise sources inside the refrigerator 100 such as fan operation, refrigeration compressor, and airflow, active or passive noise reduction (such as digital filtering and noise suppression algorithms) can be added to the microphone front-end or signal processing unit to improve voice recognition accuracy. The advantage of this technical solution is that users can directly operate the device through voice commands when opening the door or taking food. Combined with the virtual control panel 301, it realizes a dual-mode interaction of voice and aerial imaging, allowing users to freely choose the most suitable control method in different situations.

[0051] Understandably, the refrigerator 100 also includes an installation box 60 with an opening. Relative to the sides of the cabinet 10, the installation box 60 is positioned in the middle of the second storage area 1012. A partition 20 connects to the installation box 60 and closes the opening. The installation box 60 is used to house the imaging component 30, the vision detection component 40, and the voice sensor 50. Positioning the installation box 60 in the middle of the second storage area 1012 relative to the sides of the cabinet 10, away from the side walls or corners of the refrigerator 100, reduces the direct impact of condensation and low temperatures on the equipment and does not significantly occupy the main food storage space. Simultaneously, since it is located inside or adjacent to the storage compartment 101, the installation box 60 needs to possess a certain degree of airtightness and moisture-proof performance to protect the internal electronic components such as the imaging component 30, the vision detection component 40, and the voice sensor 50.

[0052] Furthermore, the opening reserved on the mounting box 60 is usually directly opposite the partition plate 20. The partition plate 20 closes the opening with a corresponding connecting structure (such as screws or clips), forming a space for module embedding or maintenance. When maintenance, replacement, or cleaning of the imaging component 30, vision inspection component 40, or voice sensor 50 is required, the partition plate 20 can be removed or the access port of the mounting box 60 can be opened without extensive disassembly of other structures of the refrigerator 100.

[0053] Furthermore, a mounting box 60 is positioned in the center of the second storage area 1012 to house core functional components such as the imaging component 30, the vision detection component 40, and the voice sensor 50. Drawers are located on either side of the mounting box 60. This layout divides the second storage area 1012 into three parts: the central mounting box 60 and the drawers on the left and right sides. The symmetrical or near-symmetrical structural design not only ensures reasonable internal space partitioning but also makes the overall appearance of the appliance more concise and aesthetically pleasing. The drawers on both sides are mainly used to store food or related items, with partitioned storage meeting different capacity and category needs. The drawers are pulled out independently of the mounting box 60, ensuring that users do not affect the electronic components inside the central mounting box 60 when retrieving or placing food. Similarly, maintenance of the mounting box 60 does not require moving items inside the drawers, greatly improving the convenience of daily use. In this embodiment, the second storage area 1012 has two drawers, which provides better spatial separation and facilitates the categorized storage of food. The first storage area, 1011, is a flat shelf. Compared to drawers, the flat shelf design provides users with more storage space and can easily accommodate larger or irregularly shaped items.

[0054] In another embodiment, the mounting box 60 is directly embedded in the bottom of the storage compartment 101, and the partition plate 20 is actually the bottom wall of the storage compartment 101. Specifically, the bottom of the storage compartment 101 is provided with an embedding groove, and the mounting box 60 is installed in the embedding groove and fixedly connected to the box body 10. At the same time, the partition plate 20, as the bottom wall, covers the embedding groove and closes it. By embedding the mounting box 60 in the bottom of the storage compartment 101 and using the partition plate 20 as the bottom wall, the bottom space of the storage compartment 101 is fully utilized, allowing the upper area to be used for more food storage, greatly improving the space utilization efficiency of the storage compartment 101.

[0055] Furthermore, the mounting box 60 includes a support structure located on its inner wall. The support structure is fixedly connected to both the imaging component 30 and the vision detection component 40, providing secure support for both components. By establishing a support structure on the inner wall of the mounting box 60 and rationally arranging the mounting holes, the imaging optical path and the vision detection area can achieve consistent and stable spatial positioning. This ensures both the quality of the projected image and allows the vision detection component 40 to more accurately and reliably capture gestures, clicks, and other operations.

[0056] Specifically, the support structure includes an inclined support plate, a parallel support frame, and a sensor fixing plate. An inclined support plate is provided on the side wall of the mounting box 60 to fix the display screen, maintaining it at a pre-designed angle of 45° to 60° relative to the partition plate 20. This inclined support plate is typically connected to the inner wall of the mounting box 60 vertically or nearly vertically, and has pre-drilled screw holes or slots. The display screen is fixed to its surface or frame by screws or clips. For fine-tuning, adjusting screws or limiting slots can be provided between the inclined support plate and the display screen to allow for angle adjustments during assembly or maintenance. Since the negative refractive lens 32 needs to be parallel to the partition plate 20, a frame can be provided on the side of the mounting box 60 near the partition plate 20, which is substantially parallel to the partition plate 20. The negative refractive lens 32 can be mounted on this frame. The sensor fixing plate can be a small vertical plate inside the mounting box 60, a cantilever, or a secondary support plate connected to other support frames.

[0057] It is understood that the refrigerator 100 also includes a lighting assembly, which is disposed on the inner wall of the cabinet 10. The virtual control panel 301 has a projection surface on the inner wall of the cabinet 10, and the lighting assembly is spaced apart from the projection surface. The projection surface corresponding to the virtual control panel 301 is located in a certain area of ​​the cabinet 10 (such as the side wall or back wall), while the lighting assembly is spaced apart from this projection surface, that is, physically separated, to ensure that the illumination light does not directly illuminate or reflect onto the virtual control panel 301. By spaced apart from the projection surface and separated in physical position or illumination direction, the direct, reflected, or spot interference of illumination light on the imaging of the virtual control panel 301 can be significantly reduced or eliminated. In aerial imaging scenarios, if the light is too strong or directly illuminates the projection area, it can easily cause problems such as insufficient image brightness and reduced contrast. This embodiment can effectively maintain the clarity and stability of the projected image.

[0058] Understandably, the storage room 101 has an opening near the door, and the virtual control panel 301 is positioned near this opening. Positioning the virtual control panel 301 near the door opening makes it easier for users to see and operate it directly when the door is open. Meanwhile,

[0059] Understandably, the refrigerator 100 also includes a camera 70, which is installed on the inner wall of the cabinet 10 and located on the top of the storage compartment 101. Installing the camera 70 on the top of the storage compartment 101 provides a wider field of view, allowing a clear view of the storage conditions and food locations inside the refrigerator 100. With the cooperation of the intelligent system, it can automatically identify or remind users of information such as food type, quantity, and shelf life, improving the convenience of using the refrigerator 100.

[0060] Furthermore, the camera 70 is electrically connected to a visual sensor, which can assist the visual sensor in capturing the user's gestures in real time, especially the user's operations on the virtual control panel 301, thereby improving the accuracy of recognizing the user's gestures.

[0061] It is understandable that the partition 20 is made of glass, meaning the entire partition 20 is a light-transmitting area. Alternatively, the light-transmitting area can be made of a high-transmittance material, such as tempered glass or high-quality acrylic, and treated with anti-condensation or anti-fogging measures (such as hydrophilic / hydrophobic coatings or electrically heated films) to reduce the interference of water vapor or frost on the imaging effect. If further reduction of reflection loss is required, an anti-reflection coating can be added to the light-transmitting area or the lens surface to improve light throughput and image quality.

[0062] It is understandable that the refrigerator 100 is a double-door refrigerator 100, with two doors 80 connected to the two sides of the cabinet 10 in a pivotal manner, and the virtual control panel 301 located in the middle area of ​​the two doors 80. By placing the virtual control panel 301 in the middle area of ​​the two doors 80, the user can directly observe and operate the panel when opening or closing either door, without it being obstructed or interfered with by the opening or closing of the doors 80.

[0063] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
