[0002] As common household appliances in modern homes, refrigeration equipment is increasingly attracting attention for its intelligent and aesthetically pleasing design. In existing technologies, to enhance user experience, some refrigeration devices integrate sensor and lighting components into the door. For example, the sensor component could be a camera module installed on the door, capable of detecting human approach and triggering corresponding functions. The introduction of lighting components can create unique visual effects, satisfying users' aesthetic needs.

[0003] However, in existing technologies, the sensing and lighting components are usually set up independently and need to be installed in different positions on the door. The independent installation of the sensing module and the lighting module increases the structural complexity and production cost. The light output direction of the lighting component and the matching effect with the door's decorative structure are limited, making it difficult to create a unique and beautiful light and shadow effect. Summary of the Invention

[0004] To address the issues with the placement of sensing and lighting components in existing refrigeration equipment, the purpose of this invention is to provide a refrigeration device that combines intelligent functionality with decorative appeal. 。

[0005] To achieve the above-mentioned objectives, one embodiment of this utility model provides a refrigeration device, comprising:

[0012] As a further improvement of this utility model, the first receiving cavity is located inside the first opening, the second receiving cavity is located inside the first receiving cavity, and the lamp assembly covers the sensing assembly outside the sensing assembly.

[0013] As a further improvement of this utility model, the sensing component includes a radar human sensing module, and the sensing end is the sensing structure of the radar human sensing module;

[0014] The cooling device also includes a controller configured to control the lamp assembly to emit light after receiving a signal from the radar human detection module that the human body is detected.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0030] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0031] One embodiment of this utility model provides a refrigeration device that combines intelligent functions with decorative effects.

[0032] The refrigeration equipment in this embodiment can be a refrigerator, freezer, upright refrigerator, wine cabinet, etc. The following embodiment can be described using a refrigerator as an example.

[0033] The refrigerator includes a cabinet and a door. The door covers the opening of the cabinet and includes a frame, an inner lining, and a panel 50. The panel 50 covers the front of the frame, and a foam insulation layer can be formed between the frame, the inner lining, and the panel 50.

[0034] To clearly express the position and direction described in this embodiment, in this embodiment, the direction of gravity is defined as up and down, and the door is arranged vertically. The up and down direction can also be defined by gravity. Figure 1 As shown, the user operates the door from the front, while the cabinet is located at the rear of the door. The front, back, top, and bottom planes represent the left and right sides, respectively.

[0035] Figures 1-3 A schematic diagram of the door structure of a refrigeration device according to an embodiment of the present invention is shown. The door includes a frame and a panel 50. The panel 50 covers the front side of the frame.

[0036] The frame includes four borders: top, bottom, left, and right. One of the borders is the first border 10. The first border 10 includes a first receiving cavity 11, a second receiving cavity 13, a first opening 12, and a second opening 14. The first receiving cavity 11 is connected to the first opening 12, and the orientation of the first opening 12 is parallel to the plane where the panel 50 is located. The second receiving cavity 13 is connected to the second opening 14, and the second opening 14 faces the panel 50.

[0037] In this embodiment, the first frame 10 extends along the width direction of the door. The first frame 10 is located at the bottom of the door.

[0038] The orientation of the first opening 12 is parallel to the plane on which the panel 50 is located. Here, the plane on which the panel 50 is located is the plane containing the top, bottom, left, and right sides. The orientation of the first opening 12 is parallel to the plane containing the top, bottom, left, and right sides, that is, the downward orientation of the first opening 12 is located in the plane containing the top, bottom, left, and right sides.

[0039] The second opening 14 faces the direction of the panel 50, i.e., forward. The first receiving cavity 11 is located inside the first opening 12. The second receiving cavity 13 is located inside the first receiving cavity 11.

[0040] The "inner side" here refers to the position where the second receiving cavity 13 is located further inside when viewed from below through the first opening 12, i.e., when looking up at the first receiving cavity 11 and the second receiving cavity 13.

[0041] The cooling equipment also includes a lamp assembly 20 and a sensor assembly 30.

[0042] The lamp assembly 20 is disposed in the first receiving cavity 11, and the light emitted by the lamp assembly 20 is emitted outward through the first opening 12.

[0043] The sensing component 30 is disposed within the second receiving cavity 13. The sensing component 30 includes a sensing end 311, which senses through the second opening 14. The sensing component 30 is used to detect when a human body approaches the refrigeration device.

[0044] Figure 4 A cross-sectional view of the first frame 10 is shown. The second receiving cavity 13 is located above the first receiving cavity 11, and the lamp assembly 20 is located below the sensing assembly 30.

[0045] In this embodiment, the first frame 10 is integrally formed from metal or plastic. There may be no clear boundary between the first receiving cavity 11 and the second receiving cavity 13; instead, they are distinguished by different shapes, for example... Figure 5 and Figure 6 In the middle, the first receiving cavity 11 is elongated, and the second receiving cavity 13 is block-shaped.

[0046] The first opening 12 is located on the lower surface of the first frame 10, and the second opening 14 is located at the front. The lamp assembly 20 is fixed in the first receiving cavity 11 by snap-fit. The sensor assembly 30 is fixed in the second receiving cavity 13 by snap-fit.

[0047] The refrigeration device in this embodiment simplifies the structural design of the door by integrating a lamp assembly 20 and a sensor assembly 30 within the first frame 10. The lamp assembly 20 serves both as illumination and covers the sensor assembly 30 below it, saving material used to cover the sensor assembly 30. Furthermore, the closer proximity between the sensor assembly 30 and the lamp assembly 20 facilitates faster and more convenient intelligent control, improving ease of use.

[0048] Furthermore, such as Figures 1-4 As shown, the refrigeration equipment includes a first door frame 40, which is adjacent to the first side frame 10. The first door frame 40 includes a diffuse reflector 41, which is inclined toward the first opening 12, and the plane of the diffuse reflector 41 is inclined to the plane of the panel 50.

[0049] The diffuse reflector 41 is a planar structure made of light-transmitting plastic or a material with a diffuse reflective coating on its surface.

[0050] The diffuse reflector 41 is tilted toward the first opening 12. The plane of the diffuse reflector 41 is set at an angle to the plane of the panel 50. The angle is preferably between 30° and 60° to ensure that the light emitted by the lamp assembly 20 can effectively illuminate the surface of the diffuse reflector 41 and be presented to the outside in the form of reflection or diffuse reflection.

[0051] In this embodiment, the light emitted by the lamp assembly 20 is projected downwards through the first opening 12. The light is diffused after hitting the diffuse reflector 41, creating a soft lighting effect. The distance and angle between the first door frame 40 and the first side frame 10 can be set as needed to ensure the luminous effect of the diffuse reflector 41 when the lamp assembly 20 is turned on.

[0052] This design enhances the light diffusion effect through the diffuse reflector 41, improving the visual comfort under the cooling equipment.

[0053] Furthermore, the first frame 10 is the bottom frame of the door, the first opening 12 faces downward, the second opening 14 faces forward, the first door frame 40 is located below the first frame 10, and a wave pattern is provided on the diffuse reflector 41.

[0054] The wave pattern structure in this embodiment is manufactured using a die-pressing or engraving process. The crests and troughs of the wave pattern are arranged alternately along the width direction of the first door frame 40. The depth of the wave pattern ranges from 0.5 mm to 2 mm, and the width ranges from 3 mm to 15 mm.

[0055] Light emitted from the lamp assembly 20 shines through the first opening 12 onto the corrugated structure. The light is refracted and diffused on the corrugated surface, creating a dynamic light and shadow effect. The corrugated structure enhances the decorative quality of the light, making the refrigeration equipment more aesthetically pleasing. The interplay of the corrugated pattern and light enhances the visual appeal of the refrigeration equipment.

[0056] Furthermore, an upwardly extending handle groove 15 is formed from the first opening 12 toward the first receiving cavity 11.

[0057] The handle groove 15 extends along the width direction of the first frame 10. The opening of the handle groove 15 faces downward and communicates with the first opening 12. The depth of the handle groove 15 extends upward along the height direction of the door body.

[0058] The space of the handle groove 15 is part of the space of the first receiving cavity 11, and the width of the handle groove 15 is slightly larger than the gripping range of the user's fingers. The lamp assembly 20 is installed in the first receiving cavity 11 above the handle groove 15. The light from the lamp assembly 20 shines downward through the first opening 12 to the outside of the handle groove 15.

[0059] The handle groove 15 facilitates the user's grip on the door for opening operations. The design of the handle groove 15, combined with the arrangement of the first receiving cavity 11, ensures that the installation of the light assembly 20 does not affect the grip function.

[0060] Furthermore, the first receiving cavity 11 is located inside the first opening 12, the second receiving cavity 13 is located inside the first receiving cavity 11, and the lamp assembly 20 covers the sensing assembly 30 outside the sensing assembly 30.

[0061] The first receiving cavity 11 extends upward along the height of the door body and is directly connected to the first opening 12.

[0062] The lamp assembly 20 is located outside the sensing assembly 30. That is, the lamp assembly 20 is located below the sensing assembly 30, and the lamp assembly 20 serves to enclose the sensing assembly 30.

[0063] Panel 50 can be made of a light-transmitting material to ensure that the detection function of sensor 311 is not affected.

[0064] This design eliminates the need for an additional cover plate required for the sensor component 30 in traditional designs by having the lamp component 20 cover the sensor component 30 from below.

[0065] Furthermore, the sensing component 30 includes a radar human sensing module 31, and the sensing end 311 is the sensing structure of the radar human sensing module 31.

[0066] The radar human detection module 31 employs microwave radar technology. The sensing end 311 is the sensing structure of the radar human detection module 31, consisting of an antenna and a signal processing unit. The sensing end 311 faces the panel 50 through the second opening 14 and is used to detect human activity in front of the door.

[0067] The cooling equipment also includes a controller configured to control the lamp assembly 20 to emit light after receiving a signal from the radar human detection module 31 that the human body is detected.

[0068] The controller is an embedded microprocessor located on a circuit board inside the door. The controller is electrically connected to the radar human detection module 31 and the light assembly 20 via wires. When the radar human detection module 31 detects the presence of a human body, it generates an electrical signal. This electrical signal is transmitted to the controller via wires.

[0069] After receiving the electrical signal, the controller outputs a control command. The control command drives the lamp assembly 20 to emit light. After the lamp assembly 20 is lit, light is emitted outward through the first opening 12. When the radar human detection module 31 does not detect a human body, it stops sending signals, and the controller controls the lamp assembly 20 to turn off.

[0070] The detection range can be adjusted by setting the sensitivity of the radar human detection module 31, preferably within the range of 0.3 meters to 2 meters. This design enables the light assembly 20 to automatically illuminate when a human body approaches, improving the intelligence and convenience of use.

[0071] Furthermore, such as Figure 5 and 8 As shown, the sensing component 30 includes a sensing bracket 32, a first snap-fit ​​part 131 is provided in the second receiving cavity 13, a second snap-fit ​​part 321 is provided on the sensing bracket 32 ​​to snap-fit ​​the first snap-fit ​​part 131, and the radar human sensing module 31 is detachably connected to the sensing bracket 32.

[0072] The sensor bracket 32 ​​is a plastic part, manufactured by injection molding. The sensor bracket 32 ​​has a rectangular frame structure and is used to support the radar human detection module 31. The radar human detection module 31 is detachably connected to the sensor bracket 32 ​​by screws or snap-fit ​​connections.

[0073] The first latching part 131 is a groove structure located on the inner wall of the second receiving cavity 13. The second latching part 321 is a hook that matches the first latching part 131. The hook engages in the groove, fixing the sensing bracket 32 ​​in the second receiving cavity 13.

[0074] During disassembly, pressing the first latching part 131 of the sensing bracket 32 ​​disengages the second latching part 321 from the first latching part 131. The radar human detection module 31 is then removed along with the sensing bracket 32. This design facilitates the installation and replacement of the sensing component 30, reducing maintenance difficulty.

[0075] Furthermore, such as Figure 2 and 7 As shown, a third latching part 113 is provided in the first receiving cavity 11, and a fourth latching part 221 is provided on the lamp assembly 20 to latch the third latching part 113. The lamp assembly 20 is inserted into the first receiving cavity 11 from the first opening 12 and latches with the third latching part 113.

[0076] The third latching portion 113 consists of multiple latching slots spaced apart along the inner wall of the first receiving cavity 11. The depth of the latching slots is 3 mm to 5 mm. The fourth latching portion 221 is a buckle that matches the third latching portion 113 and protrudes from the side of the lamp assembly 20.

[0077] The lamp assembly 20 is inserted into the first receiving cavity 11 through the first opening 12. During insertion, the fourth locking part 221 aligns with the third locking part 113. After pressure is applied, the fourth locking part 221 is inserted into the third locking part 113, achieving a locking and fixing. The light-emitting surface of the lamp assembly 20 faces the first opening 12 to ensure normal light output.

[0078] During disassembly, the fourth snap-fit ​​part 221 is disengaged from the third snap-fit ​​part 113 by pulling the lamp assembly 20. This design uses a snap-fit ​​method to fix the lamp assembly 20, which facilitates assembly and disassembly and improves production efficiency.

[0079] Furthermore, the lamp assembly 20 includes a lamp strip 21 and a lamp cover 22, both of which extend along the direction of the first frame 10. The light emission direction of the lamp strip 21 is towards the first opening 12, and the lamp cover 22 is disposed on the side of the lamp strip 21 facing the first opening 12. The lamp cover 22 is detachably connected to the first frame 10.

[0080] The light strip 21 is an LED light strip arranged along the extension direction of the first frame 10. The light strip 21 includes multiple LED light-emitting units, with the light emission direction facing the first opening 12. The light strip 21 is powered by a flexible circuit board and fixed to the bottom of the first receiving cavity 11.

[0081] The lampshade 22 is made of transparent or translucent polycarbonate material. The length of the lampshade 22 matches that of the light strip 21.

[0082] The inner surface of the lampshade 22 is attached to the lamp strip 21, and the outer surface faces the first opening 12.

[0083] The lampshade 22 has a fourth snap-fit ​​part 221 on both sides, i.e., a snap-fit ​​structure. The lampshade 22 is detachably connected to the first frame 10 by the snap-fit. During installation, the lampshade 22 is pressed in from the first opening 12, and the snap-fit ​​is inserted into the slot to fix it. During disassembly, the lampshade 22 can be separated by pulling it outward.

[0084] This design, through the combination of light strip 21 and lampshade 22, ensures uniform light output while facilitating the replacement and maintenance of lampshade 22.

[0085] Furthermore, the first receiving cavity 11 includes opposing first sidewalls 111 and second sidewalls 112, and the distance between the first sidewalls 111 and the second sidewalls 112 gradually increases along the direction from the first receiving cavity 11 to the first opening 12.

[0086] The first sidewall 111 and the second sidewall 112 are arranged one in front of the other. The cross-section of the first receiving cavity 11 is approximately trapezoidal. The width near the bottom of the first receiving cavity 11 is smaller, so that when light propagates from the first receiving cavity 11 to the first opening 12, the trapezoidal structure expands the illumination range of the light.

[0087] This design enhances the lighting effect of the lamp assembly 20 and improves the uniformity of light output.

[0088] Compared with the prior art, this embodiment has the following beneficial effects:

[0089] The cooling device houses the lamp assembly 20 and the sensor assembly 30 within the first receiving cavity 11 and the second receiving cavity 13 of the first frame 10, respectively, and achieves light output and sensing functions through the first opening 12 and the second opening 14. The lamp assembly 20 not only provides illumination but also acts as a cover for the sensor assembly 30, eliminating the need for an additional cover plate required for the sensing module in traditional designs. This reduces production materials and assembly processes, lowering manufacturing costs and complexity. Furthermore, the sensing end 311 of the sensor assembly 30 faces the panel 50 through the second opening 14, effectively detecting when a person approaches the cooling device. The light emitted by the lamp assembly 20 is projected outwards through the first opening 12, satisfying both lighting and intelligent detection requirements, providing users with a more efficient and aesthetically pleasing user experience.

[0090] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0091] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
