Description

Technical Field

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

[0002] The freezer compartment of a refrigerator is usually located on the bottom of the refrigerator. Users usually have to bend over to take out items, which often blocks the light inside the freezer compartment, making it difficult to see the items in the drawers. Therefore, it is necessary to install a lighting unit in the freezer compartment.

[0003] Conventional freezers use a single light source for their lighting components, resulting in limited illumination intensity. This makes it difficult to achieve a better user experience when the drawers are well-lit, especially in larger freezer compartments with many drawers. Problems arise where the upper drawers are too brightly lit or the bottom drawers are too dimly lit, failing to meet user expectations. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a refrigerator.

[0006] This design features a freezer compartment with a controlled freezing temperature and multiple drawers housing the drawer assembly. These drawers are movably connected to the freezer body and can be pulled out or pushed back in. During drawer movement, a corresponding trigger is activated, which then uses an electrical signal to control a lighting component that emits light of varying brightness. As different drawers move, different position sensors are triggered, allowing the lighting component to emit different lights depending on the drawer's movement. At least two triggers are housed in a mounting box, which provides a semi-enclosed space to securely hold the assembly inside the refrigerator. This provides mechanical support, preventing the triggers from shifting due to drawer movement or vibration, ensuring stable detection, especially considering the low temperature and humidity inside the freezer compartment, which may contain condensation or frost. The mounting box, with its panel and side panels forming mounting grooves, provides a degree of protection for the triggers, preventing direct exposure to the environment and extending their lifespan. Furthermore, it adopts a modular design, which facilitates the quick installation or replacement of trigger components during production or maintenance, improves maintainability, simplifies the assembly process, and can be assembled into a single component before being assembled with the freezer body.

[0007] In one embodiment, the mounting box extends along the height of the refrigerator, the mounting box includes a front panel and a side panel, the side panel is connected to the outer periphery of the front panel and cooperates with the front panel to form a mounting groove, and the trigger is disposed in the mounting groove.

[0008] In one embodiment, the panel has a mounting base on the side wall forming the mounting groove, and two mounting bases are spaced apart along the height direction of the refrigerator. The trigger is engaged with the mounting base.

[0009] In one embodiment, the panel has a through hole that connects the mounting slot and the freezer compartment, and the through hole corresponds to the opening of the trigger.

[0010] In one embodiment, the side panel is provided with a buckle that engages with the wall of the freezer body.

[0013] In one embodiment, the freezer housing includes a compressor compartment, and a portion of the freezer housing forming the compressor compartment is constructed as an inclined surface, with the third trigger disposed on the inclined surface.

[0014] In one embodiment, the first trigger, the second trigger, and the third trigger are all configured as radar position sensors, capable of detecting changes in distance from the drawer assembly, and triggering the illumination assembly in response to changes in position.

[0015] In one embodiment, the lighting component is connected to the top of the freezer body, and the first trigger, the second trigger, and the third trigger are respectively electrically connected to the lighting component;

[0016] The lighting component has a first light, a second light, and a third light with different brightness levels.

[0030] This utility model provides a refrigerator 100, which has a light-emitting component 30 capable of emitting light of different brightness. A trigger component 40 is used to trigger the light-emitting component 30 to emit light of different brightness when different drawers are pulled out, so as to adapt to drawers in multiple different positions such as upper, middle and lower, and make the light more uniform.

[0031] Please see Figures 1-5 The refrigerator 100 includes a freezer body 10, a drawer assembly 20, a lighting assembly 30, and a trigger assembly 40. The freezer body 10 has a freezer compartment inside. The drawer assembly 20 includes multiple drawers, all of which are movably connected to the freezer body 10 and housed in the freezer compartment, and are arranged along the height of the refrigerator 100. The lighting assembly 30 is connected to the freezer body 10. The trigger assembly 40 includes a mounting box 41 and multiple trigger elements 42. At least two trigger elements 42 are disposed in the mounting box 41, which is connected to the freezer body 10. The multiple trigger elements 42 are correspondingly disposed with the multiple drawers, and the trigger elements 42 are configured to trigger the lighting assembly 30 to emit light of different brightness in response to the movement of the drawer assembly 20.

[0032] Thus, the freezer compartment has a freezing temperature and houses multiple drawers of the drawer assembly 20. These drawers are movably connected to the freezer body 10 and can be pulled out or pushed back in. During drawer movement, trigger elements 42, each corresponding to a drawer, are activated. These trigger elements 42 then control the illumination assembly 30 to emit light of varying brightness via electrical signals. As different drawers move, different position sensors are triggered, thus controlling the illumination assembly 30 to emit different lights according to the moving drawers. At least two trigger elements 42 are installed within the mounting box 41. Therefore, the mounting box 41 provides a semi-enclosed space to accommodate multiple trigger elements 42, securely fixing the trigger assembly 40 inside the refrigerator 100. This provides mechanical support, preventing the trigger elements 42 from shifting due to drawer movement or vibration, ensuring the stability of detection, especially since the freezer compartment environment is low-temperature and humid, potentially containing condensation or frost. The mounting box 41 forms mounting grooves 413 through the panel 411 and side panels 412, providing a degree of protection for the trigger elements 42, preventing direct exposure to the environment and extending their lifespan. Furthermore, the modular design facilitates the quick installation or replacement of the trigger element 42 during production or maintenance, improving maintainability and simplifying the assembly process. It can be assembled into a single component and then assembled together with the freezer body 10.

[0033] Preferably, in this embodiment, the drawer assembly 20 includes three drawers: a first drawer 21, a second drawer 22, and a third drawer 23, arranged along the height of the refrigerator 100. There are also three triggers 42: a first trigger 43, a second trigger 44, and a third trigger 45, arranged along the height of the refrigerator 100 and corresponding one-to-one with the first drawer 21, the second drawer 22, and the third drawer 23. The first trigger 43 and the second trigger 44 are located in the mounting box 41 along the height of the refrigerator 100, while the third trigger 45 is located below the mounting box 41 and spaced apart from it, thus corresponding to the third drawer 23.

[0034] Thus, when the first drawer 21 is pulled out, the first trigger 43 is activated, transmitting an electrical signal to the lighting component 30. The lighting component 30 then emits corresponding light based on the movement signal of the first drawer 21. Similarly, when the second drawer 22 and the third drawer 23 are pulled out, the lighting component 30 can emit corresponding light. When the upper drawer is pulled out, the light is relatively weak, while when the lower drawer is pulled out, the light is stronger, thereby providing a uniform lighting effect.

[0035] Specifically, the trigger 42 is equipped with a radar position sensor. By specifically setting the trigger 42 as a radar position sensor, the movement of the drawer is detected using the radar wave ranging principle. This non-contact detection method has higher reliability and durability compared to mechanical switches or contact sensors, avoiding the risks of mechanical wear, freezing adhesion, or physical contact failure.

[0036] Furthermore, the mounting box 41 extends along the height direction of the refrigerator 100. The mounting box 41 includes a front panel 411 and a side panel 412. The side panel 412 is connected to the outer periphery of the front panel 411 and cooperates with the front panel 411 to form a mounting groove 413. The trigger 42 is disposed in the mounting groove 413. In this way, by limiting the extension of the mounting box 41 along the height direction of the refrigerator 100, the mounting box 41 can better adapt to the vertical layout of the multi-layer drawers in the freezer compartment of the refrigerator 100, realizing the rationalization of the structure and the efficient use of space. The cooperation of the front panel 411 and the side panel 412 forms a stable accommodating space, providing reliable mechanical support for the trigger 42, preventing it from shifting due to vibrations caused by the opening and closing of the drawers, and also forming a certain degree of protection, avoiding direct corrosion of the trigger 42 by cold air, moisture or condensation in the freezer compartment, thereby improving the working stability and service life of the entire trigger assembly 40.

[0037] Furthermore, the panel 411 has mounting seats 414 on the side wall forming the mounting groove 413. Two mounting seats 414 are spaced apart along the height direction of the refrigerator 100, and the trigger 42 engages with the mounting seat 414. This engagement of the trigger 42 with the mounting seat 414 achieves precise positioning and rapid installation of the trigger 42 within the mounting box 41. The spaced-apart mounting seats 414 ensure that multiple triggers 42 can correspond one-to-one with drawers of different heights, avoiding mutual interference and ensuring accurate detection. The snap-fit ​​connection simplifies the assembly process, eliminating the need for additional screws or other fasteners, thus improving production efficiency and maintainability.

[0038] A through-hole 4111 is provided on the panel 411, corresponding to the connection between the mounting slot 413 and the freezer compartment. This provides an unobstructed detection channel for the trigger 42, i.e., the aforementioned radar position sensor, enabling it to accurately sense changes in the drawer's position and ensuring detection sensitivity and reliability. At the same time, the main structure of the mounting box 41 still effectively protects the trigger 42, preventing direct impact from items inside the drawer or user operations.

[0039] The side panel 412 is equipped with a clip 4121, which snaps onto the wall of the freezer body 10. In this way, the mounting box 41 can be fixed to the wall of the freezer body 10 by snapping, realizing the quick installation and removal of the mounting box 41, eliminating the need for traditional screw fixing, and simplifying the production assembly and subsequent maintenance and replacement process.

[0040] Furthermore, the freezer body 10 has an inner wall 13 and an outer wall 14. The inner wall 13 forms a freezer compartment. A positioning groove is formed on the wall of the freezer body 10, penetrating both the inner wall 13 and the outer wall 14. The mounting box 41 is installed in the positioning groove, and the buckle 4121 is engaged with the edge of the positioning groove. The side panel 411 facing the freezer compartment is flush with the inner wall 13. This design ensures that the trigger component 40 does not occupy additional storage space, maintains the flatness and smoothness of the inner wall 13 of the freezer compartment, and avoids protruding structures affecting the normal pulling out of the drawer or creating cleaning dead corners. The method of securing the buckle 4121 with the edge of the positioning groove further ensures the installation strength and stability of the mounting box 41 on the freezer body.

[0041] The freezer compartment 10 includes a compressor compartment 12. The portion of the freezer compartment 10 forming the compressor compartment 12 is constructed as a slope 11, and a third trigger 45 is disposed on the slope 11. By disposing the third trigger 45 on the slope 11 of the compressor compartment 12, the structural characteristics of the bottom space of the refrigerator 100 are adapted, interference between the third trigger 45 and the compressor or other components is avoided, ensuring the feasibility of detection and signal stability of the third drawer 23 (the bottom drawer), and guaranteeing the integrity and reliability of the entire system under complex structures.

[0042] In this embodiment, along the height direction of the refrigerator 100, the lighting component 30 is located at the top of the freezer compartment 10, the first drawer 21 is located at the top, the second drawer 22 is located in the middle, and the third drawer 23 is located at the bottom. Therefore, when the first drawer 21 is pulled out, the light emitted by the lighting component 30 is the weakest, while when the third drawer 23 is pulled out, the light emitted by the lighting component 30 needs to be the strongest, and when the second drawer 22 is pulled out, the lighting component 30 emits moderate light.

[0043] Specifically, the lighting component 30 is connected to the top of the freezer body 10, and the first trigger 43, the second trigger 44, and the third trigger 45 are electrically connected to the lighting component 30 respectively. The lighting component 30 has a first light, a second light, and a third light with different brightness. The first light is triggered by the first trigger 43, the second light is triggered by the second trigger 44, and the third light is triggered by the third trigger 45. The brightness of the third light is greater than that of the second light, and the brightness of the second light is greater than that of the first light.

[0044] In this way, by setting up a one-to-one correspondence between three drawers and three trigger components 40, independent lighting control for drawers of different heights is achieved, allowing the light intensity to be intelligently adjusted according to the drawer position. This layout significantly improves the uniformity of lighting inside the freezer, especially alleviating the problem of insufficient lighting in the lower layers due to their depth; users can obtain suitable brightness when operating at different heights, reducing visual fatigue, improving user satisfaction and product ergonomics, and making items on each layer clearly visible, thus solving the pain point that traditional single lighting cannot simultaneously address lighting at different depths.

[0045] In addition, the lighting assembly 30 also includes a trigger lever 31, which extends forward along the depth of the refrigerator 100 and abuts against the door of the refrigerator 100, controlling the working state of the lighting assembly 30. This achieves an intelligent control function of automatically turning on the light when the door is opened and automatically turning off the light when the door is closed. This mechanism further improves energy efficiency, avoids wasting electricity by keeping the light on continuously, and reduces manual operation by the user, enhancing ease of use. The trigger lever 31 has a simple and reliable structure, good durability, and is suitable for high-frequency daily use scenarios. It also prevents the lighting assembly 30 from remaining off even if the trigger assembly 40 located at the rear malfunctions after prolonged use and becomes easily triggered, or if the trigger assembly 40 remains in the triggered state due to the drawer not being fully pushed in, thus preventing continuous lighting due to these abnormal reasons and avoiding wasted electricity.

[0046] Please see Figure 5 The lighting component 30 also includes a base 32 and a light strip 33. The base 32 is installed on the freezer cabinet, and the light strip 33 is embedded in it and can emit a first light, a second light, and a third light.

[0047] Understandably, if the refrigerator 100 is provided with four drawers in other embodiments, a fourth trigger component 40 and a fourth light can be added accordingly, and it is not limited to embodiments with three of each.

[0048] Compared to existing technologies, this invention integrates and securely mounts multiple trigger elements 42 within the freezer body 10 using a mounting box 41, creating a device that intelligently responds to different drawer opening and closing states by emitting lights of varying brightness. The mounting box 41 ensures precise positioning and reliable detection of each trigger element 42 with its corresponding drawer, driving the top lighting component 30 to emit light with brightness matching the drawer's position. This provides a uniform and comfortable visual experience for each drawer, significantly enhancing the user experience.

[0049] The refrigerator 100 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the refrigerator 100 to perform corresponding operations, thereby realizing intelligent control of the refrigerator 100 and improving the user experience.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
