Description

Technical Field

[0001] This disclosure relates to the field of refrigerators equipped with ambient light strips, and more particularly to refrigerators. Background Technology

[0002] Refrigerators, as an indispensable necessity in modern households, have become ubiquitous in their use, evolving from traditional food refrigeration and freezing functions towards intelligent, personalized, and aesthetically pleasing designs. As users' demands for quality of life increase, the need for expanded refrigerator functions is growing. Among these, ambient lighting has become an important feature for enhancing the refrigerator's appearance and user experience. Currently, most mid-to-high-end refrigerators on the market have ambient lighting installed in their internal storage compartments or on the exterior door surfaces. This creates a warm and inviting atmosphere and helps users quickly locate door handles or check door status in low-light environments.

[0003] However, existing external ambient lighting designs for refrigerators still have significant technical limitations: due to the structural characteristics of the refrigerator door itself, some key areas cannot effectively install ambient light strips due to spatial layout or interference from moving parts, resulting in "lighting dead zones" that seriously affect the overall aesthetics and the integrity of the lighting effect. Specifically, the support and rotation of the refrigerator door rely on the door hinge structure, which is usually located at the edge of the door between the refrigerator and freezer drawers. This structure includes moving parts such as pivots and connectors, and the installation space is compact. Traditional straight ambient light strips are difficult to install here because they cannot adapt to the irregular space of the hinge area and the risk of movement interference. At the same time, for refrigerator doors with a double-door structure, there must be a certain width of gap between the adjacent sides of the two doors to ensure normal opening and closing. There is no fixed mounting surface in this gap area, and there is relative movement when the doors open and close, so traditional ambient light strips cannot be installed here either.

[0004] The "unlit areas" at the door hinges and refrigerator door gaps result in incomplete illumination coverage by the external ambient light. When the ambient light is on, these areas create a stark contrast between light and dark with the surrounding lit areas, disrupting the overall lighting uniformity, reducing the refrigerator's aesthetic appeal, and failing to meet users' needs for overall visual harmony.

[0005] Therefore, how to design an ambient lighting solution that can adapt to the structural characteristics of special structural areas such as the hinges and gaps of the refrigerator door and achieve complete lighting coverage has become a technical problem that urgently needs to be solved in the field of refrigerator ambient lighting design. Utility Model Content

[0006] This disclosure provides a refrigerator to solve the technical problem in the prior art that ambient lights cannot be installed in special structural areas such as the hinges and gaps of the refrigerator door.

[0007] The refrigerator provided by this utility model includes a refrigerator body, an ambient light strip, and a control system. The refrigerator body includes a refrigerator door and a freezer drawer located below the refrigerator door. A door hinge is provided between the refrigerator door and the freezer drawer, and a refrigerator door gap is formed between multiple refrigerator doors. The ambient light strip is provided on the lower end cover of the refrigerator door. The end of the ambient light strip near the door hinge and the end near the refrigerator door gap are respectively inclined so that the light from the ambient light strip covers the door hinge and the refrigerator door gap. The control system is electrically connected to the ambient light strip and is used to control the opening or closing of the ambient light strip.

[0008] The lower end cover of the refrigerator door is provided with an installation groove, and the ambient light strip is arranged along the installation groove. The area of ​​the installation groove corresponding to the inclined end of the ambient light strip has an adaptive inclined structure.

[0009] The mounting groove includes a straight section extending along the length of the refrigerator door and inclined sections connected to both ends of the straight section. The extension direction of the inclined sections corresponds to the positions of the door hinge and the refrigerator door gap, respectively. The non-inclined part of the ambient light strip is attached to the straight section, and the inclined end is attached to the inclined section.

[0010] The ambient light strip is constructed as a flexible wire light strip, and the tilt angle of the ambient light strip near the door hinge end and near the refrigerator door gap end is both between 30° and 60°.

[0011] The refrigerator door includes two symmetrically arranged double doors, with a gap between the two double doors, and an ambient light strip is provided on the lower end cover of each double door.

[0012] The ambient light strip has multiple LED beads spaced apart, with each LED bead emitting light towards the top cover of the freezer door drawer, so that the light evenly covers the top cover of the freezer door drawer.

[0013] The refrigerator body also includes a door switch sensor, which is electrically connected to the control system and is used to detect the opening and closing status of the refrigerator door or the freezer door drawer. When the door switch sensor detects that the refrigerator door or the freezer door drawer is open, the control system controls the ambient light strip to turn off.

[0014] The refrigerator also includes a human body sensor, which is electrically connected to the control system and is used to detect whether a user is near the refrigerator. The control system is configured to control the ambient light strip to turn on or off based on the detection signal from the human body sensor.

[0015] The refrigerator also includes a display module located in front of the refrigerator door for operating refrigerator functions, and the human body sensor is integrated into the display module.

[0016] The display module is embedded in the door panel of the refrigerator door, and the operating surface of the display module is flush with the outer surface of the door panel to avoid structural interference when the door is opened and closed.

[0017] Compared with the prior art, the technical solutions provided in this disclosure have the following advantages: The refrigerator provided in this embodiment, by tilting the ambient light strips near the ends of the door hinges and refrigerator door gaps, allows the light to bypass structural areas where light strips cannot be installed in the traditional way, precisely covering the door hinge surface and refrigerator door gaps. This avoids the uneven lighting problem caused by lighting only in non-structural interference areas, resulting in a complete and uniform distribution of external lighting for the refrigerator, significantly improving its aesthetic appearance. Through electrical connection between the control system and the ambient light strips, the system can control the opening and closing of the light strips according to actual usage needs, avoiding the ineffective power consumption caused by traditional ambient lights being constantly on, reducing the overall energy consumption of the refrigerator, and meeting energy-saving requirements. In this way, the evenly covered light can help users quickly locate the refrigerator door handle and identify the freezer drawer position in low-light environments, avoiding operational errors caused by insufficient light, such as accidentally touching the door hinges. Furthermore, the on-demand opening and closing control logic eliminates the need for manual operation by the user, improving ease of use and comfort. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0025] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement 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," "front," "back," 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 undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will 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. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0026] This disclosure uses a French door refrigerator as an example. The structure and function of the refrigerator are designed to solve the technical problem of uneven lighting caused by the inability to install ambient light strips in the door hinges and refrigerator door gaps. At the same time, it improves the user experience through intelligent control. The structure, working principle and technical effects are described in detail below.

[0027] refer to Figures 1-3 The refrigerator with ambient light strip 2 provided in this embodiment includes: a refrigerator body 1, an ambient light strip 2, and a control system. The refrigerator body 1 includes a refrigerator door 11 and a freezer door drawer 12 located below the refrigerator door 11. A door hinge 13 is provided between the refrigerator door 11 and the freezer door drawer 12, and a refrigerator door gap 14 is formed between the multiple refrigerator doors 11. The ambient light strip 2 is provided on the lower end cover 111 of the refrigerator door 11. The end of the ambient light strip 2 near the door hinge 13 and the end near the refrigerator door gap 14 are respectively inclined so that the light of the ambient light strip 2 covers the door hinge 13 and the refrigerator door gap 14. The control system is electrically connected to the ambient light strip 2 and is used to control the opening or closing of the ambient light strip 2.

[0028] Thus, the refrigerator body 1 includes a refrigerator door 11 and a freezer door drawer 12 located below it. A door hinge 13 is installed between the refrigerator door 11 and the freezer door drawer 12, and a refrigerator door gap 14 is formed between multiple refrigerator doors 11. These two areas are difficult to install with traditional straight-line ambient light strips 2 due to their structural characteristics. This solution places the ambient light strip 2 on the lower end cover 111 of the refrigerator door 11. By tilting the ends of the light strip near the door hinge 13 and near the refrigerator door gap 14, the light from the light strip bypasses the structural interference area, covering both the main body area of ​​the upper end cover 121 of the freezer door drawer 12 and the surface of the door hinge 13 and the gap 14 of the refrigerator door, thus solving the problem of uneven lighting caused by traditional lighting only in non-structural interference areas.

[0029] Meanwhile, the electrical connection between the control system and the ambient light strip 2 enables on-demand control. When the refrigerator is running normally and there is no need for use, the control system defaults to turning off the ambient light strip 2 to avoid unnecessary power consumption and ambient light interference. When the system detects that the user intends to use the refrigerator, it receives a trigger signal and sends a power-on command to turn on the ambient light strip 2 and provide full illumination to the door hinge 13, the refrigerator door gap 14, and the upper cover 121 of the freezer drawer 12. After the user's use is completed, the control system sends a power-off command to turn off the light strip, ensuring a balance between illumination function and energy-saving requirements.

[0030] In summary, by tilting the ambient light strip 2, the problem of blind spots in lighting where the door hinge 13 and refrigerator door gap 14 cannot be fitted with the light strip is completely solved, resulting in uniform external lighting distribution, effectively improving the refrigerator's aesthetic appearance and mitigating the visual defects of uneven lighting in traditional solutions. The precise control logic of the control system avoids energy waste from the ambient light strip 2 remaining constantly lit, reducing the overall power consumption of the refrigerator. Furthermore, the uniform lighting coverage provides clear visual assistance for users, enhancing operational convenience and perfectly meeting the core need to improve the user experience.

[0031] Considering the structural scheme of the installation scenario of the ambient light strip 2, in the refrigerator provided in this embodiment, the lower end cover 111 of the refrigerator door 11 is provided with an installation groove 1111, the ambient light strip 2 is arranged along the installation groove 1111, and the area of ​​the installation groove 1111 corresponding to the inclined end of the ambient light strip 2 has an adapted inclined structure.

[0032] The mounting groove 1111 of the lower end cover 111 of the refrigerator door 11 adopts a segmented fitting structure. Its overall extension trajectory is completely matched with the shape of the ambient light strip 2. That is, the straight section 1111A extending along the length of the refrigerator door 11 is used to fit the middle non-sloping part of the ambient light strip 2. Corresponding to the sloping end of the ambient light strip 2 near the door hinge 13 and near the refrigerator door gap 14, the mounting groove 1111 is provided with a matching sloping section 1111B. The extension direction of the sloping section 1111B is consistent with the sloping direction of the end of the light strip, and the sloping angle matches the sloping angle of the end of the light strip, ensuring that the light strip fits without gaps after being embedded. During installation, the ambient light strip 2 is embedded along the extension trajectory of the mounting groove 1111. The light strip of the straight section 1111A fits tightly against the straight section 1111A of the groove, and the light strip of the inclined end fits tightly against the inclined section 1111B of the groove. This not only prevents the ambient light strip 2 from shifting or loosening due to vibrations caused by the opening and closing of the door, but also ensures, through the structural constraint of the groove, that the inclined end of the light strip is precisely aligned with the area where the door hinge 13 and the gap 14 of the refrigerator door are located, providing a structural basis for subsequent lighting coverage.

[0033] During operation, the segmented structure of the mounting groove 1111 directly ensures the illumination function of the ambient light strip 2: the middle part of the light strip constrained by the straight section 1111A of the groove can evenly cover the main area of ​​the upper cover 121 of the freezer door drawer 12, meeting the user's illumination needs for the main area outside the refrigerator; while the end of the light strip constrained by the inclined section 1111B of the groove can directly illuminate the surface of the door hinge 13 and the gap 14 of the refrigerator door along the inclined direction. Due to the support structure of the door hinge 13 and the opening and closing requirements of the refrigerator door gap 14, the light strip cannot be directly installed in these two areas. The traditional solution would create a blind spot in illumination if only a straight light strip is used. In this embodiment, the inclined section 1111B of the groove guides the end of the light strip to tilt, so that the light bypasses the structural obstacles and accurately covers the above-mentioned blind spot area. Moreover, the angle setting of the inclined section 1111B ensures that the light in this part and the light in the straight section 1111A form a seamless illumination superposition on the upper cover 121 of the freezer door drawer 12, avoiding the appearance of light and dark discontinuities.

[0034] In this way, the installation groove 1111 first solves the positioning deviation problem of traditional ambient light strip 2 installation. Without a matching groove, the tilted end of the light strip is prone to angle deviation due to installation errors, and the light cannot cover the target area. However, this embodiment controls the error of the light strip installation angle to a very small range through the structural constraint of the groove, ensuring the stability of the light coverage. Secondly, the groove's wrapping installation of the light strip significantly improves the structural stability of the light strip, preventing the light strip from loosening or falling off during frequent opening and closing of the door, and extending the life of the light strip. Finally, this structure does not require modification to the existing door hinge 13 and refrigerator door gap 14 structure of the refrigerator. It can be achieved simply by opening a groove in the lower end cover 111 of the refrigerator door 11. It has strong compatibility, and the close fit between the light strip and the groove keeps the appearance of the lower end cover 111 of the refrigerator door 11 flat, avoiding structural redundancy caused by the protruding light strip, further improving the aesthetics of the refrigerator exterior, while meeting the core requirement of uniform lighting.

[0035] Considering the specific installation scheme of the ambient light strip 2 relative to the mounting groove 1111, in the refrigerator provided in this embodiment, the mounting groove 1111 includes a straight section 1111A extending along the length direction of the refrigerator door 11, and inclined sections 1111B respectively connected to both ends of the straight section 1111A. The extension direction of the inclined sections 1111B corresponds to the positions of the door hinge 13 and the refrigerator door gap 14, respectively. The non-inclined part of the ambient light strip 2 is attached to the straight section 1111A, and the inclined end is attached to the inclined section 1111B.

[0036] In this way, the segmented structure of the mounting groove 1111 is adapted to the structural characteristics of the refrigerator door 11 and the shape requirements of the ambient light strip 2: the straight section 1111A extending along the length of the refrigerator door 11 has the same length as the non-inclined part of the ambient light strip 2. The non-inclined part is the middle main section, which can provide a stable installation reference for the light strip along the lateral direction of the refrigerator door 11; while the inclined sections 1111B connected to both ends of the straight section 1111A do not have random extension directions. The inclined section 1111B near the door hinge 13 extends towards the edge door area where the door hinge 13 is located, and the inclined section 1111B near the refrigerator door gap 14 extends towards the gap area between the two refrigerator doors 11. The inclination angle and length of the inclined section 1111B are completely matched with the angle and length of the inclined end of the ambient light strip 2, ensuring that the light strip and the groove form a gapless and close installation relationship. During installation, the non-sloping portion of the ambient light strip 2 fits tightly against the straight section 1111A of the groove. The non-sloping portion covers the main body area of ​​the upper cover 121 of the freezer door drawer 12. The side wall of the straight section 1111A of the groove constrains the light strip to prevent lateral displacement. The two sloping ends of the ambient light strip 2 are respectively embedded in the corresponding sloping sections 1111B of the groove. The two sloping ends cover the door hinge 13 and the gap 14 of the refrigerator door. The side wall of the sloping section 1111B simultaneously restricts the angular displacement of the light strip ends, so that the orientation of the sloping ends of the light strip is always accurately aligned with the door hinge 13 and the gap 14 of the refrigerator door, providing structural positioning guarantee for subsequent lighting coverage.

[0037] During operation, the segmented structure of the mounting groove 1111 directly determines the effectiveness of the ambient light strip 2's illumination coverage. Specifically, the non-inclined portion of the light strip constrained by the straight section 1111A of the groove can project light evenly along the length of the refrigerator door 11 onto the main body area of ​​the upper cover 121 of the freezer door drawer 12, meeting the illumination needs of the core area outside the refrigerator. Meanwhile, the inclined end of the light strip constrained by the inclined section 1111B of the groove, because the extension direction of the inclined section 1111B corresponds to the position of the door hinge 13 and the refrigerator door gap 14, can project light from the end of the light strip along the direction guided by the inclined section 1111B, bypassing the interference of the moving parts of the door hinge 13 and avoiding the lack of an installation surface in the refrigerator door gap 14, directly onto the gap between the door hinge 13 and the refrigerator door gap 14, which cannot be covered by traditional solutions. Meanwhile, because the light strip fits perfectly with each section of the groove, even if the refrigerator door 11 is frequently opened and closed and vibrates, the light strip will not change its tilt angle due to displacement, thus maintaining stable illumination of the target area and avoiding light shift or dead angles caused by loose light strips.

[0038] This solution first addresses the interference issue between the ambient light strip 2 installation and the refrigerator door structure: the segmented design of the mounting groove 1111 eliminates the need to modify the original door hinge 13 or refrigerator door gap 14 structure of the refrigerator door 11. Precise installation of the light strip is achieved solely through the groove's shape, avoiding the installation difficulties caused by traditional straight light strips that cannot adapt to the hinge and gap structures, thus ensuring strong compatibility. Secondly, it ensures the stability and uniformity of light coverage: the groove's fit and constraint on the light strip minimizes the tilt angle error, allowing the light to stably cover the door hinge 13 and refrigerator door gap. 14. Furthermore, the lights from the straight section 1111A and the inclined section 1111B form a seamless lighting superposition on the upper cover 121 of the freezer door drawer 12, without any light or dark breaks, thus completely improving the uneven lighting defects of traditional solutions. Finally, it enhances structural reliability and aesthetic coordination: the light strip is embedded in the groove, which provides a wrapping protection for the light strip, reducing the impact of door vibration on the light strip and extending its service life. At the same time, after the light strip is installed in the groove, there are no protruding parts on the surface of the lower cover 111 of the refrigerator door 11, maintaining a flat appearance and avoiding structural redundancy caused by protruding light strips, thus meeting the overall requirements of the refrigerator's appearance design.

[0039] Considering the specific construction and installation scheme of the ambient light strip 2, in the refrigerator provided in this embodiment, the ambient light strip 2 is constructed as a flexible wire light strip, and the tilt angle of the ambient light strip 2 near the end of the door hinge 13 and near the end of the refrigerator door gap 14 is a value between 30° and 60°.

[0040] The ambient light strip 2 is constructed as a flexible wire light strip. Its core feature is that it has the structural advantages of being flexible and easy to shape. It can fully adapt to the installation scenario requirements of the lower end cover 111 of the refrigerator door 11. For the non-straight installation area at the door hinge 13 and the refrigerator door gap 14, the flexible wire light strip can bend naturally with the change of the installation path. Without additional cutting or splicing, it can closely fit the contour of the corresponding area of ​​the lower end cover 111 of the refrigerator door 11. This avoids the structural interference between the traditional rigid light strip and the door hinge 13 and the refrigerator door gap 14 due to the inability to bend. It ensures that the light strip is stably arranged in the preset installation position, providing a structural foundation for the subsequent accurate coverage of the target area by the light.

[0041] Meanwhile, the ambient light strip 2 is tilted at an angle of 30°-60° at the end near the door hinge 13 and the end near the refrigerator door gap 14. This angle range is determined based on precise calculations of the refrigerator door structure and lighting requirements: if the tilt angle is less than 30°, the light at the end of the light strip will not be able to cover the surface of the door hinge 13 and the gap of the refrigerator door 14 due to the small illumination angle, and will still form a blind spot; if the tilt angle is greater than 60°, the light will be too diffused, resulting in insufficient illumination of the door hinge 13 and the gap area, and some light will shine on non-target areas of the refrigerator cabinet, such as the ground and walls, resulting in wasted light. The 30°-60° tilt angle range allows the light from the end of the light strip to be precisely projected onto the surface of the door hinge 13 and the refrigerator door gap 14 along a preset trajectory. Simultaneously, it creates a seamless lighting superposition with the light from the straight section 1111A of the ambient light strip 2 on the upper cover 121 of the freezer drawer 12, ensuring uninterrupted illumination across the entire area of ​​the upper cover 121 of the freezer drawer 12, the door hinge 13, and the refrigerator door gap 14, thus meeting the core requirement of uniform lighting. For example, the straight section 1111A extends along the length of the lower cover 111 of the refrigerator door 11.

[0042] First, the flexible light strip's design solves the installation pain points of traditional rigid light strips: it eliminates the need to modify the original structure of the refrigerator door hinges 13 and refrigerator door gaps 14, adapting to non-straight installation paths solely through the light strip's own flexibility. This simplifies the installation process, reduces assembly difficulty, and avoids the risk of reduced refrigerator door strength due to structural modifications. Second, the 30°-60° tilt angle range ensures effective and economical lighting coverage, eliminating blind spots at the door hinges 13 and refrigerator door gaps 14, improving uneven external lighting distribution, enhancing overall aesthetics, and preventing energy waste caused by excessive light diffusion. Finally, the flexible structure of the flexible light strip makes it less prone to loosening, falling off, or breaking under the vibration of frequent refrigerator door opening and closing, resulting in a longer lifespan compared to rigid light strips. This further improves the reliability of the refrigerator ambient lighting system, while the uniform illumination provides clear visual assistance for users operating the refrigerator in low-light environments, indirectly enhancing the user experience.

[0043] Considering the specific location scheme of the ambient light strip 2 on the refrigerator door 11, in the refrigerator provided in this embodiment, the refrigerator door 11 includes two symmetrically arranged double doors 112, and the refrigerator door gap 14 is formed between the two double doors 112. The ambient light strip 2 is provided on the lower end cover 111 of each double door 112.

[0044] In this way, the refrigerator door 11 adopts a structure of two symmetrically arranged double doors 112. This structure not only meets the needs of large-capacity storage in the refrigerator, but also, due to the symmetrical layout of the two doors, naturally forms a refrigerator door gap 14 extending vertically on the adjacent sides. Based on this structural characteristic, each double door 112 has an independent ambient light strip 2 installed on its lower end cover 111. The overall arrangement trajectory of the light strip is adapted to the length direction of the lower end cover 111 of the corresponding double door 112. The straight section 1111A extending along the width of the double door 112 covers the main area of ​​the upper end cover 121 of the freezer drawer 12 on that side. The ends of the light strips near the door hinge 13 are tilted to match the hinge position and the gap position, respectively. This ensures that the light strip on a single double door 112 can independently cover its own side door hinge 13, the area of ​​the upper end cover 121 of the corresponding freezer drawer 12, and half of the area of ​​the freezer gap 14, laying the structural foundation for the coordinated illumination of the two light strips.

[0045] During operation, the ambient light strips 2 on the two double doors 112 form a symmetrical and coordinated lighting coverage logic: the ambient light strip 2 on the left double door 112 projects light towards the right side of the gap from its inclined end near the gap, while the ambient light strip 2 on the right double door 112 projects light towards the left side of the gap from its inclined end near the gap. The two light strips overlap in the gap 14 area of ​​the refrigerator door, providing sufficient and uniform lighting to the gap area where light strips could not be installed due to the door's opening and closing requirements. Simultaneously, the left... The light strip of the side-opening door 112 covers the left side of the left door hinge 13 and the left side of the upper cover 121 of the freezer drawer 12, while the light strip of the right-opening door 112 covers the right side of the right door hinge 13 and the right side of the upper cover 121 of the freezer drawer 12. Combined with the superimposed lighting at the gaps, the refrigerator's exterior is fully illuminated, including the left hinge, the left drawer area, the gaps, the right drawer area, and the right hinge. This avoids the problem of blind spots in lighting on the other side of the hinge and gaps when only one side is equipped with a light strip.

[0046] First, this solution precisely solves the problem of blind spots in the symmetrical double-door structure 112: the light strips of the two double-door 112 respectively cover the door hinges 13 on their respective sides, while the opposing inclined ends work together to cover the refrigerator door gap 14. Compared with the solution of setting light strips only on one side of the double-door 112, it completely eliminates the dark area at the far end of the hinge and gap on the other side, making the external light distribution of the refrigerator more complete. Second, the symmetrical arrangement of light strips ensures uniform illumination: the illumination range of the two light strips forms a seamless connection in the upper cover 121 of the freezer door drawer 12 and the gap area, without any dark spots. The distinct light and shadow separation creates a more unified overall lighting effect when viewed from the front of the refrigerator, significantly enhancing its aesthetic appeal. Finally, this solution boasts excellent structural compatibility: the light strips are only located on the lower end cover 111 of each side-by-side door 112, eliminating the need to modify the original opening and closing structure and hinge layout of the symmetrical side-by-side doors 112. This adapts to existing manufacturing processes for side-by-side door 112 refrigerators, reducing modification costs and assembly difficulty. Furthermore, the independent placement of the two light strips facilitates future maintenance; if one side of the light strip malfunctions, only the corresponding side needs to be replaced, without requiring complete disassembly, thus improving usability.

[0047] Considering the specific display scheme of the ambient light strip 2, in the refrigerator provided in this embodiment, a plurality of LED beads 3 are arranged at intervals on the ambient light strip 2, and the light emission direction of each LED bead 3 is towards the upper end cover 121 of the freezer door drawer 12, so that the light evenly covers the upper end cover 121 of the freezer door drawer 12.

[0048] The LED beads 3 of the ambient light strip 2 are positioned and their light emission direction is closely adapted to the lighting requirements of the upper cover 121 of the freezer door drawer 12. Multiple LED beads 3 are arranged at intervals along the extension direction of the ambient light strip 2. The spacing is determined based on the area of ​​the upper cover 121 of the freezer door drawer 12, the length of the ambient light strip 2, and the illumination range of a single LED bead 3. By calculating the effective illumination radius of the LED beads 3 at a preset power, the spacing of the LED beads 3 is set to be less than twice the effective illumination radius. This ensures that the illumination range of adjacent LED beads 3 overlaps in the upper cover 121 of the freezer door drawer 12, avoiding illumination breaks or dark areas due to excessive spacing. At the same time, the light emission direction of all LED beads 3 is directed towards the upper cover 121 of the freezer door drawer 12, rather than radiating to the side or downward. The optical structure of the LED beads 3 constrains the light propagation path, concentrating the light on the upper cover 121 area and reducing ineffective projection onto non-target areas such as the ground and the sides of the refrigerator cabinet.

[0049] During operation, the spaced LED beads 3 work together with their directional light emission characteristics to achieve uniform illumination coverage of the upper cover 121 of the freezer door drawer 12: the LED beads 3 arranged along the straight section 1111A of the ambient light strip 2, where the straight section 1111A corresponds to the straight area of ​​the lower cover 111 of the refrigerator door 11, project their directional light vertically or obliquely onto the main body area of ​​the upper cover 121 of the freezer door drawer 12. Due to the overlapping of light from adjacent LED beads 3, the illuminance in this area is uniform and there is no obvious difference in brightness; along The ambient light strip 2 has LED beads 3 arranged on its inclined section 1111B. The inclined section 1111B is close to the end of the door hinge 13 and the refrigerator door gap 14. Although the light strip itself is inclined, the light emission direction of the LED beads 3 still faces the upper cover 121. Its light can cover the edge area of ​​the upper cover 121 near the hinge and gap, and form a seamless connection with the light of the LED beads 3 on the straight section 1111A in the edge area. This avoids the problem of the main body being bright and the edges being dark caused by the messy light emission direction of traditional LED beads 3. In addition, if the refrigerator door 11 is a symmetrical double door 112 structure, each double door 112 has an ambient light strip 2 on its lower cover 111. The light of the LED beads 3 on both sides can be superimposed in the middle of the upper cover 121 of the freezer drawer 12. The middle of the upper cover 121 of the freezer drawer 12 corresponds to the area below the refrigerator door gap 14, further ensuring sufficient illumination in this intersection area and achieving uniform illumination of the entire upper cover 121 without dead angles.

[0050] First, this solution completely solves the core pain point of uneven illumination in traditional ambient lighting: through optimized spacing and directional light emission of the LED beads 3, the illuminance variance of the upper cover 121 of the freezer door drawer 12 is controlled within a very small range, making it impossible for users to perceive differences in brightness with the naked eye. Compared to solutions where the LED beads 3 are randomly arranged or have chaotic light emission directions, the uniformity of illumination is significantly improved. Second, the light utilization rate is greatly improved: the directional light emission setting towards the upper cover 121 ensures that more than 90% of the light emitted by the LED beads 3 is applied to the target area, avoiding energy waste caused by traditional diffused light emission. Under the same illuminance requirements, the overall power of the ambient light strip 2 can be reduced, meeting the energy-saving requirements of the refrigerator. Finally, it provides real convenience for users: in dimly lit environments, the uniformly covered light can clearly show the outline and position of the upper cover 121 of the freezer door drawer 12, helping users quickly locate the drawer pull-out and reducing operational errors caused by blurred vision. At the same time, the uniform lighting effect also makes the exterior visual appearance of the refrigerator more unified, improving the overall aesthetics and meeting the quality requirements of refrigerator appearance design.

[0051] Considering the linkage control scheme between the refrigerator's opening and closing status and the ambient light strip 2's opening and closing status, in the refrigerator provided in this embodiment, the refrigerator body 1 further includes a door switch sensor. The door switch sensor is electrically connected to the control system and is used to detect the opening and closing status of the refrigerator door 11 or the freezer door drawer 12. When the door switch sensor detects that the refrigerator door 11 or the freezer door drawer 12 is in the open state, the control system controls the ambient light strip 2 to turn off.

[0052] In this way, the door opening / closing sensors are precisely adapted to the refrigerator door structure. For the different opening and closing methods of the refrigerator door 11 and the freezer drawer 12, sensors are installed in corresponding detection positions: the door opening / closing sensor for the refrigerator door 11 is embedded on the door hinge side of the refrigerator door 11, adjacent to the door hinge 13, and determines the open / closed state of the refrigerator door 11 by sensing the relative displacement between the door and the cabinet; the door opening / closing sensor for the freezer drawer 12 is installed at the end of the slide rail of the freezer drawer 12, and determines the open / closed state of the drawer by sensing the sliding travel of the drawer and the slide rail. All door opening / closing sensors are electrically connected to the control system via wires. During operation, the sensors convert the detected mechanical state of the door (open / closed) into electrical signals, which are transmitted to the control system in real time, providing the door status basis for the opening and closing control of the ambient light strip 2. When the sensor detects that the refrigerator door 11 or the freezer drawer 12 has switched from closed to open, it immediately sends a door opening signal to the control system; when it detects that the door has switched from open to closed, it sends a door closing signal.

[0053] The control system, based on the signal from the door switch sensor, forms a door-state-priority linkage control logic with the ambient light strip 2, and this logic is deeply matched with the lighting function of the ambient light strip 2. The core function of the ambient light strip 2 is to cover the door hinge 13, the refrigerator door gap 14, and the upper cover 121 of the freezer drawer 12. When the door switch sensor sends a door opening signal, the control system will prioritize triggering the ambient light strip 2 to turn off: In the scenario where the refrigerator door 11 is open, the open door will block the ambient light strip 2 on its lower cover 111, and the light cannot be projected onto the hinge, gap, and upper cover 121 of the drawer, so continuing to light it has no practical lighting significance; In the scenario where the freezer drawer 12 is open, the pulled-out drawer will be out of the original lighting area, and the light strip lighting will also lose its function. Conversely, when the sensor sends a door closing signal, the control system will combine it with other triggering conditions, such as a user approach signal from the human body sensor. If it is determined that the user still has a need for use, such as the user not leaving the refrigerator, the control system will turn the ambient light strip 2 back on to ensure that the lighting function of the target area is quickly restored after the door is closed, and to avoid the lack of lighting support for subsequent operations due to the door being open for a short time.

[0054] The solution applied in this embodiment avoids the light strip from illuminating ineffectively after the door is opened. Real-world testing shows that compared to control methods without door linkage, the average daily ineffective illumination time of the ambient light strip 2 is significantly reduced, resulting in a substantial decrease in the refrigerator's overall energy consumption. Secondly, it effectively improves user comfort: if the ambient light strip 2 remains illuminated when the door is open, light can easily shine directly into the user's eyes through the gap in the open door, causing visual discomfort. The linkage shutdown setting completely avoids this problem, improving the user experience. Finally, it works in synergy with the original control logic of the ambient light strip 2, such as human body sensing triggering: the light strip turns on when a user approaches, turns off when the door is opened, and restarts if the user does not leave after the door is closed. This forms a coherent control process of sensor-activated opening, door-opening closing, and door-closing restart, ensuring effective illumination of the target area while avoiding functional redundancy. This makes the control logic of the ambient light strip 2 more aligned with actual user habits, further optimizing the refrigerator's intelligence and practicality.

[0055] Considering the scheme of the control system controlling the opening and closing of the ambient light strip 2 based on the detection signal of the sensor, the refrigerator provided in this embodiment of the disclosure further includes a human body induction sensor, which is electrically connected to the control system and is used to detect whether a user is near the refrigerator; the control system is configured to control the opening or closing of the ambient light strip 2 according to the detection signal of the human body induction sensor.

[0056] In this way, the control system forms the ambient light strip 2 control logic based on the detection signal of the human body sensing sensor, which is triggered on demand and dynamically adjusted. This logic is deeply adapted to the structural settings of the ambient light strip 2, taking into account the arrangement of the lower end cover 111 of the refrigerator door 11 and the limitation of the tilt at both ends. When the control system receives a user proximity signal from the sensor, it immediately sends a power-on command to the ambient light strip 2. At this time, the straight section 1111A of the ambient light strip 2 covers the main body area of ​​the upper cover 121 of the freezer door drawer 12, and the two inclined ends cover the door hinge 13 and the refrigerator door gap 14 respectively, achieving comprehensive full-area illumination of the upper cover 121, hinge, and gap of the freezer door drawer 12, avoiding the problem of uneven lighting caused by lighting only in some areas. When the control system receives no user signal from the sensor, it sends a power-off command to turn off the light strip, reducing unnecessary energy consumption. At the same time, combined with the implicit requirement of the ambient light turning off when the refrigerator door is opened, if the user opens the refrigerator door 11 or the freezer door drawer 12, the door status can be detected by the refrigerator's original door control components. Even if the human body sensor still has a signal, the control system will prioritize controlling the light strip to turn off. At this time, the opened door will block the light, and continuing to keep the light on has no practical effect and may also cause discomfort to the user's eyes from direct light, further optimizing the rationality of the control logic.

[0057] It should be noted that the combination of the human body sensor and the control system firstly solves the pain points of traditional refrigerator ambient lights being constantly on, consuming excessive power, or requiring cumbersome manual switching. Through the logic of automatically turning on when the user approaches and automatically turning off when they leave, the ambient light strip 2's daily effective on-time is only a fraction of the time in the traditional constant-on mode. The specific percentage of time can be set according to actual application needs, significantly reducing the overall energy consumption of the refrigerator and meeting the energy-saving requirements of home appliances. Secondly, it enhances the user experience. In dimly lit environments, such as a kitchen at night, the light strip automatically turns on when the user approaches the refrigerator, providing even illumination to assist in... The system allows users to quickly locate the handle of the refrigerator door 11 and identify the position of the freezer door drawer 12, avoiding operational errors caused by insufficient ambient light, such as accidentally touching the door hinge 13, thus improving the user experience of using the refrigerator. Finally, this sensor control scheme works synergistically with the tilted structure of the ambient light strip 2. The tilted light strip solves the problem of blind spots in lighting, while the sensor control ensures that lighting is provided on demand. The combination of the two enhances the aesthetics of the refrigerator, i.e., uniform lighting throughout the entire area, and also improves ease of use, i.e., intelligent opening and closing, thus making up for the dual deficiencies of traditional refrigerator ambient lights in terms of structural adaptation and intelligent control.

[0058] Considering the display function scheme of the refrigerator based on sensors, the refrigerator provided in this embodiment of the present disclosure further includes a display module, which is located in front of the refrigerator door 11 and is used to operate the refrigerator functions. The human body sensing sensor is integrated into the display module.

[0059] In this way, the installation position and functional settings of the display module are closely adapted to the daily use scenarios of the refrigerator. It is fixedly installed in the front door area of ​​the refrigerator door 11, which is within the user's natural line of sight and hand movement range when operating the refrigerator. The user can reach it with a simple raise of their hand and operate the refrigerator's core functions, such as adjusting the temperature of the refrigerator and freezer compartments, switching between quick cooling and quick freezing modes, or setting the refrigerator's timer function, without having to search for an additional operating interface, thus improving the convenience of function operation. At the same time, the human body sensor is integrated into the display module, specifically embedded in the non-operating area of ​​the display module, such as the corner, so as not to obstruct the display interface and operating components, and to ensure that the sensor's detection angle covers the user's normal activity area in front of the refrigerator, such as the path of the user walking towards the refrigerator in the kitchen, and determines whether the user is approaching the refrigerator by capturing human infrared signals. During operation, the human body sensor converts the detected user location signal into an electrical signal, which is directly transmitted to the refrigerator's control system through the internal circuitry of the display module. This eliminates the need for additional independent signal lines and provides a precise triggering basis for the subsequent opening and closing control of the ambient light strip 2. If the user does not enter the detection range or leaves the detection range for more than a preset time, the sensor sends a no-user signal to the control system, cutting off the triggering condition for the ambient light strip 2 to turn on.

[0060] The display module, human body sensor and control system form a collaborative control logic, and this logic is deeply adapted to the structure of the ambient light strip 2, such as the arrangement of the lower end cover 111 of the refrigerator door 11 and the tilt of both ends. When the control system receives a user approach signal from the human body sensor via the display module, it immediately sends a power-on command to the ambient light strip 2. At this time, the straight section 1111A of the ambient light strip 2 can cover the main body area of ​​the upper cover 121 of the freezer door drawer 12, while the two inclined ends cover the door hinge 13 and the refrigerator door gap 14 respectively, achieving full-area illumination of key areas outside the refrigerator and avoiding uneven lighting caused by partial lighting. If the user operates the refrigerator functions through the display module after approaching the refrigerator, the display module will synchronize the user's continuous presence signal to the control system while executing the operation command, ensuring that the ambient light strip 2 remains on and providing stable lighting support for the user's operation. In addition, when the user opens the refrigerator door 11 or the freezer door drawer 12, even if the human body sensor still detects the user signal, the control system will prioritize controlling the ambient light strip 2 to turn off. At this time, the opened door will block the light of the ambient light, and continuing to light it will have no practical lighting significance and may also cause discomfort to the user's eyes due to direct light, further optimizing the rationality of the control logic.

[0061] This solution first addresses the structural redundancy issue of separate display modules and sensing components in traditional refrigerators: the human body sensor is integrated into the display module, eliminating the need for additional holes or mounting brackets in the refrigerator door 11, simplifying the overall structure of the refrigerator door 11, and maintaining the flatness and uniformity of the door's appearance, avoiding the cluttered appearance of the door panel 113 caused by separate installation components. Second, it significantly improves the user experience: the front-mounted position of the display module makes operation more convenient, and the automatic detection function of the human body sensor enables the ambient light strip 2 to be turned on as needed. Users do not need to manually switch the lights on or off; they can automatically obtain uniform lighting when approaching the refrigerator in dimly lit environments, assisting in quickly locating the door handle and drawer positions and reducing operational errors. Finally, it optimizes the system's stability and energy efficiency: the sensor and display module share the same wiring to transmit signals, reducing the risk of faults such as poor contact and aging wiring that may occur with separate wiring, and improving control stability. At the same time, based on the logic of turning on only when the user approaches and turning off when they leave, the ambient light strip 2 does not need to be constantly lit, effectively reducing the overall energy consumption of the refrigerator and meeting the energy-saving requirements of home appliances.

[0062] Considering the specific installation scheme of the display module relative to the refrigerator door 11, in the refrigerator provided in this embodiment, the display module is embedded in the door panel 113 of the refrigerator door 11, and the operating surface of the display module is flush with the outer surface of the door panel 113 of the refrigerator door 11 to avoid structural interference when the door is opened and closed.

[0063] In this way, the installation structure of the display module is adapted to the depth of the door panel 113 of the refrigerator door 11. The door panel 113 of the refrigerator door 11 has a pre-cut installation cavity that matches the outer dimensions of the display module. The depth of the installation cavity is consistent with the thickness of the display module, ensuring that after the display module is fully installed, its operating surface remains flush with the outer surface of the door panel 113. The edge of the display module is fixed to the inner wall of the installation cavity by a suitable snap-fit ​​or adhesive structure, which not only prevents the display module from loosening or shifting during the opening and closing of the door, but also maintains the flush state between the operating surface and the outer surface of the panel, preventing surface unevenness caused by unstable fixing.

[0064] During operation, the embedded structure seamlessly integrates with the opening and closing motion of the refrigerator door 11: when the refrigerator door 11 opens, it rotates around the door hinge 13, and the outer surface of its door panel 113 must avoid the refrigerator cabinet, another refrigerator door 11, and other structures within the rotation trajectory. Since the operating surface of the display module is flush with the outer surface of the panel and has no protrusions, the display module will not collide or rub against the cabinet side panel or adjacent doors during the rotation of the refrigerator door 11, completely eliminating the problem of interference with other structures caused by traditional protruding display modules. Furthermore, even if the refrigerator door 11 vibrates due to frequent opening and closing, the fixedly embedded display module maintains a stable position and will not cause the operating surface to protrude due to vibration, thus maintaining a seamless opening and closing environment.

[0065] First, this solution directly solves the structural interference problem between the display module and the door switch: compared to the traditional protruding display module, which has a higher interference rate during opening and closing, the flush-mounted design reduces the risk of interference during the opening and closing of the refrigerator door 11 to zero, ensuring smooth door opening and closing and avoiding damage to the door or display module due to interference. Second, it improves the appearance integrity of the refrigerator door 11: the display module is flush with the outer surface of the door panel 113, with no obvious splicing gaps or protrusions, making the overall visual effect of the door panel 113 more unified and improving the problem of protruding installation disrupting the door's appearance coordination. Finally, it optimizes the user experience and structural reliability: the flush operating surface allows users to touch or press buttons without any bumps or obstructions, resulting in a smoother operating feel; the flush-mounted fixing is more resistant to vibrations from door opening and closing than the protruding type, reducing the probability of the display module loosening or falling off, extending its service life, while not compromising the original structural strength of the door panel 113, ensuring the overall performance stability of the refrigerator door 11.

[0066] In summary, in the refrigerator using this embodiment, a door hinge 13 is provided on the edge of the door between the refrigerator door 11 and the lower freezer drawer 12 to support the rotation and opening of the refrigerator door 11. The door hinge 13 is a key structure that prevents the installation of the ambient light strip 2. A refrigerator door gap 14 is formed between the two double-leaf refrigerator doors 11, which is also an area that traditional light strips cannot cover due to the need for door opening and closing. To address this constraint, this solution places the ambient light strip 2 on the lower end cover 111 of the refrigerator door 11, that is, on the side facing the freezer drawer 12, and the end of the light strip is inclined.

[0067] For example, the two ends of the ambient light strip 2 are not set in a traditional straight strip shape, but are inclined at the positions of the door hinge 13 and the refrigerator door gap 14 respectively. The end of the light strip near the door hinge 13 is inclined towards the edge of the door where the hinge is located; the end of the light strip near the refrigerator door gap 14 is inclined towards the adjacent gap between the two refrigerator doors 11. This inclined setting can avoid interference from the moving parts of the hinge, while a traditional straight light strip would collide with the hinge pivot and connecting parts. At the same time, it utilizes the linear propagation characteristics of light to allow the light to bypass the structural areas where the light strip cannot be installed, and directly cover the hinge surface and the gap.

[0068] The ambient light strip 2 is not designed as a traditional straight strip at both ends. Instead, it is angled towards the door hinge 13 and the refrigerator door gap 14. Specifically, the end of the light strip near the door hinge 13 is angled towards the edge of the door where the hinge is located, while the end of the light strip near the refrigerator door gap 14 is angled towards the adjacent gap between the two refrigerator doors 11. This angled design avoids interference from the moving parts of the hinge, whereas a traditional straight light strip would collide with the hinge pivot and connecting parts. Furthermore, by utilizing the linear propagation characteristics of light, the light bypasses structural areas where light strips cannot be installed, directly covering the hinge surface and the gap.

[0069] Regarding the application of the control system, when the refrigerator is working normally and there is no user operation, the control system defaults to turning off the ambient light strip 2 to avoid the power waste caused by traditional ambient lights being constantly on, and to prevent light from interfering with the home environment, such as light pollution in the living room at night. When a user approaches the refrigerator, for example, in a scenario where they are preparing to take out or put away food, the sensor transmits a detection signal to the control system, and the control system immediately sends a power-on command to the ambient light strip 2, turning on the light strip and providing full-area illumination, which can be understood as full-area illumination covering the hinges, gaps, and the top cover 121 of the freezer door drawer 12. When the user opens the refrigerator door 11 or the freezer door drawer 12, the control system identifies the door status through the door switch detection component. At this time, the light from the ambient light strip 2 will be blocked by the open door and cannot illuminate the target area. The control system then sends a power-off command, and the light strip turns off. After the user closes the door, if the sensor still detects that the user is nearby, the control system turns the light strip on again to ensure a balance between the user's lighting needs and energy-saving needs throughout the user's operation.

[0070] In this way, the angled arrangement of the light strip ends allows light to directly cover the aforementioned dark areas. Specifically, the ambient light strip 2 covers the upper cover 121 of the freezer door drawer 12, which helps users quickly locate the pull-out position of the freezer door drawer 12 in low-light environments. At the same time, the illumination of the hinge area can prevent users from accidentally touching the hinge components when opening the door, as traditional dark areas can easily lead to hand bumps. The on-demand lighting logic of the control system avoids the cumbersome operation of traditional manual light switching and prevents light interference from constantly lit lights. For example, the light strip does not turn on when the user only passes by the refrigerator at night. The lights only turn on when the user intends to use the appliance, which meets the user's comfortable need for seamless interaction with home appliances.

[0071] Furthermore, the tilting setting of the ambient light strip 2 does not require modification to the existing door hinge 13 or refrigerator door 11 structure. Only a shallow groove for the light strip needs to be made in the lower end cover 111 of the refrigerator door 11. It can be directly adapted to multi-door refrigerators with refrigeration and freezer drawers with open door 112. The modification cost is low and it is easy to apply in batches. The control system defaults to turning off the light strip, which, combined with the linkage of turning off the light when the door is opened, shortens the average daily effective operating time of the ambient light strip 2.

[0072] In summary, this solution addresses the core issue of the inability to install light strips in the door hinge 13 and gaps by adapting the inclined structure of the ambient light strip 2. It also improves the user experience through intelligent linkage of the control system, while making up for the technical deficiencies of traditional refrigerator ambient lights.
