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.

[0005] A refrigerator includes: a freezer body having a freezer compartment inside; a drawer assembly including multiple drawers, all of which are movably connected to the freezer body and housed in the freezer compartment; a lighting assembly connected to the freezer body; and a trigger assembly connected to the freezer body, the trigger assembly including a trigger element and a contact switch, the trigger element abutting against the drawer assembly and capable of triggering the contact switch in response to movement of the drawers, the contact switch being electrically connected to the lighting assembly; wherein there are multiple trigger assemblies, and each trigger assembly can emit light of different brightness in response to movement of different drawers.

[0006] This configuration allows the freezer compartment to maintain a freezing temperature and houses multiple drawers assemblies. These drawers are movably connected to the freezer body and can be pulled out or pushed back in. During drawer movement, triggers activate components that actuate a contact switch. The contact switch then uses an electrical signal to control the lighting component, which emits light of varying brightness. Because there are multiple trigger components, it can accommodate multiple drawers. When different drawers move, different trigger components are activated, thus allowing the lighting component to emit different lights depending on the moving drawer.

[0007] In one embodiment, the triggering component further includes a trigger seat connected to the freezer body, and the trigger seat has a mounting groove in which the trigger element and the contact switch are both mounted.

[0008] In one embodiment, the trigger is elastically connected to the trigger seat and has a first position and a second position, which is capable of moving between the first position and the second position in response to external pressure; wherein, when not under pressure, the trigger is located in the first position and protrudes from the side of the trigger seat facing the drawer, and when the trigger abuts against the drawer, the trigger is located in the second position and triggers the contact switch.

[0009] In one embodiment, the trigger seat has a groove, the bottom of the groove has a connecting hole, a connector passes through the connecting hole, and the connector passes through the connecting hole and is connected to the freezer body.

[0010] In one embodiment, the trigger seat has a protruding rib protruding from the trigger seat. The rib is hollow and its inner wall cooperates with the mounting groove to form a mounting cavity. The rib has an opening communicating with the mounting cavity, and one end of the trigger extends out of the rib from the opening.

[0011] In one embodiment, the drawer assembly includes three drawers, namely a first drawer, a second drawer, and a third drawer, which are arranged along the height of the refrigerator; the triggering component is three, namely a first triggering component, a second triggering component, and a third triggering component, which are arranged along the height of the refrigerator and correspond one-to-one with the first drawer, the second drawer, and the third drawer.

[0012] In one embodiment, the freezer body includes a compressor compartment, and the portion of the freezer body forming the compressor compartment is constructed as an inclined surface. Along the height direction of the refrigerator, the trigger assembly located at the lowest side is disposed on the inclined surface.

[0013] In one embodiment, the triggering components are all located on the rear side of the freezer body.

[0014] In one embodiment, the illumination component is connected to the top of the freezer body, and the first trigger component, the second trigger component, and the third trigger component are respectively electrically connected to the illumination component;

[0015] The lighting component has a first light, a second light, and a third light with different brightness levels. The first light is triggered by the first triggering component, the second light is triggered by the second triggering component, and the third light is triggered by the third triggering component. 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 third light.

[0016] In one embodiment, the lighting component further includes a trigger rod that extends forward along the depth direction of the refrigerator and abuts against the refrigerator door, and is capable of controlling the operating state of the lighting component.

[0017] Compared to existing technologies, this invention sets up multiple trigger components corresponding to drawers of different heights, and enables them to automatically control the top lighting components to emit lights of different brightness according to the position of the drawer pulled out by the user. That is, the lower layer is brighter than the upper layer. This effectively solves the problem of uneven lighting caused by a single light source in the freezer compartment of traditional refrigerators, significantly improves the visibility of each drawer and the user experience, and achieves intelligent lighting control and energy-saving effects.

[0029] Please see Figures 1-4 This utility model provides a refrigerator 100, which has a light-emitting component 30 capable of emitting light of different brightness. When different drawers are pulled out by a trigger component 40, the light-emitting component 30 can emit light of different brightness to adapt to drawers in multiple different positions, such as the upper, middle and lower parts, so as to make the light more uniform.

[0030] 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 11 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 11. The lighting assembly 30 is connected to the freezer body 10. The trigger assembly 40 is connected to the freezer body 10 and includes a trigger element 41 and a contact switch. The trigger element 41 abuts against the drawer assembly 20 and can trigger the contact switch in response to the movement of the drawer. The contact switch is electrically connected to the lighting assembly 30. There are multiple trigger assemblies 40, and each can trigger the lighting assembly 30 to emit light of different brightness in response to the movement of different drawers.

[0031] Thus, the freezer compartment 11 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, a trigger 41 is activated, which in turn triggers a contact switch. The contact switch then controls the illumination assembly 30 to emit light of varying brightness via an electrical signal. Since there are multiple trigger assemblies 40, they are adapted to multiple drawers. When different drawers move, different trigger assemblies 40 are activated, thus allowing the illumination assembly 30 to emit different lights according to the moving drawers.

[0032] Preferably, in this embodiment, the drawer assembly 20 includes three drawers, namely a first drawer 21, a second drawer 22, and a third drawer 23, which are arranged along the height direction of the refrigerator 100; the trigger assembly 40 includes three trigger assemblies, namely a first trigger assembly 45, a second trigger assembly 46, and a third trigger assembly 47, which are arranged along the height direction of the refrigerator 100 and correspond one-to-one with the first drawer 21, the second drawer 22, and the third drawer 23.

[0033] Thus, when the first drawer 21 is pulled out, the first trigger component 45 is activated, transmitting an electrical signal to the illumination component 30. The illumination 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 illumination component 30 emits 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.

[0034] 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.

[0035] Specifically, the illumination component 30 is connected to the top of the freezer body 10, and the first trigger component 45, the second trigger component 46, and the third trigger component 47 are electrically connected to the illumination component 30 respectively. The illumination 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 component 45, the second light is triggered by the second trigger component 46, and the third light is triggered by the third trigger component 47. 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 third light.

[0036] 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.

[0037] Specifically, the trigger assembly 40 also includes a trigger seat 42, which is connected to the freezer housing 10. The trigger seat 42 has a mounting groove in which the trigger element 41 and the contact switch are installed. Thus, by providing the trigger seat 42 and constructing the mounting groove within it, the trigger element 41 and the contact switch can be securely and centrally installed, improving the structural integrity and assembly convenience of the trigger assembly 40. This integrated installation method effectively avoids installation errors caused by the dispersed arrangement of parts, and also facilitates later maintenance and replacement, significantly improving the manufacturability and reliability of the product. In other words, the trigger element 41 and the contact switch (not shown in the figure) can be first installed in the trigger seat 42, and then the trigger seat 42 can be installed on the freezer housing 10, simplifying the assembly process.

[0038] Furthermore, the trigger 41 is elastically connected to the trigger seat 42 and has a first position and a second position, capable of moving between the first and second positions in response to external pressure. When not under pressure, the trigger 41 is in the first position and protrudes from the side of the trigger seat 42 facing the drawer. When the trigger 41 abuts against the drawer, it is in the second position and triggers the contact switch. Thus, by elastically connecting the trigger 41 to the trigger seat 42 and allowing it to move between the first and second positions, it can reliably respond to the drawer's push-pull action and accurately trigger the contact switch. The elastic structure provides a stable rebound force, ensuring that the trigger 41 quickly resets when no external force is applied, avoiding false triggering. Simultaneously, this design has high mechanical durability, adapts to frequent operating environments, and improves the sensitivity and stability of the entire control system.

[0039] Furthermore, the trigger seat 42 has a groove 44, and a connecting hole 441 is formed at the bottom of the groove 44. A connector passes through the connecting hole 441 and is connected to the freezer body 10. Thus, the groove 44 and connecting hole 441 on the trigger seat 42, and the connector fixing it to the freezer body 10, enhance the installation stability and structural strength of the trigger assembly 40. This connection method effectively resists the vibration and impact caused by repeated opening and closing of the drawer, prevents the assembly from shifting or loosening, and ensures accurate alignment and reliable triggering during long-term use.

[0040] Furthermore, the trigger seat 42 is provided with a protruding rib 43, which protrudes from the trigger seat 42. The rib 43 is hollow, and its inner wall mates with the mounting groove to form a mounting cavity. An opening 431 communicating with the mounting cavity is provided on the rib 43, and one end of the trigger element 41 extends out of the rib 43 through the opening 431. In this way, by setting the rib 43 and forming the mounting cavity, the trigger element 41 partially extends out of the opening 431, which protects the internal structure of the trigger element 41 and ensures its effective contact with the drawer. The structure of the rib 43 plays a guiding and protective role, preventing foreign objects from entering or mechanical damage, and extending the service life of the component; at the same time, the reasonably designed opening 431 ensures smooth trigger stroke, improving the smoothness of the overall machine operation and the user experience.

[0041] Preferably, the portion of the trigger 41 extending out of the opening 431 is also connected to a contact 411, which is made of rubber to extend the service life of the trigger 41 and the drawer after prolonged contact and collision.

[0042] All trigger components 40 are located on the rear side of the freezer compartment 10. This avoids interference with the front drawer operating area, keeping the interior of the refrigerator 100 tidy. It also conceals key control components, reduces visual clutter, facilitates lighting wiring, improves internal space utilization and overall aesthetics, and prevents users from directly contacting the trigger mechanism, enhancing safety.

[0043] Understandably, in other embodiments, the trigger component 40 may also be located on the side of the freezer housing 10, as long as it can respond and trigger smoothly and accurately.

[0044] The freezer compartment 10 includes a compressor compartment. The portion of the freezer compartment 10 forming the compressor compartment is constructed as a slope 12. Along the height direction of the refrigerator 100, the trigger assembly 40, located at the lowest side, is disposed on the slope 12. This design adapts to the structural characteristics of the bottom of the freezer compartment 10, ensuring that the trigger assembly 40 can be installed and operated normally in all positions without affecting the placement of components such as the compressor in the compressor compartment. The design makes full use of the internal space structure of the refrigerator 100 and avoids interference with components such as the compressor compartment.

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

[0048] The refrigerator 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 to perform corresponding operations, thereby realizing intelligent control of the refrigerator and improving the user experience.

[0049] Compared to existing technologies, this invention sets up multiple trigger components 40 corresponding to drawers of different heights, and enables them to automatically control the top lighting component 30 to emit lights of different brightness according to the position of the drawer pulled out by the user. That is, the lower layer is brighter than the upper layer. This effectively solves the problem of uneven lighting caused by a single light source in the freezer compartment of a traditional refrigerator 100, significantly improves the visibility of each drawer and the user experience, and achieves intelligent lighting control and energy-saving effects.

[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.
