[0023] This embodiment provides a refrigerator, which includes a drawer assembly provided with a slide rail system. The drawer assembly is provided with electronic devices such as a display screen. The wiring harness of the electronic devices is arranged along the slide rail assembly, which effectively increases the usable space of the drawer while maintaining the simplicity of the drawer body structure, improving the overall space utilization, and making the product more in line with the aesthetic requirements of the modern home environment.

[0024] This embodiment provides a refrigerator comprising a storage space formed within a housing. The storage space may include multiple compartments, such as a refrigerator, a fresh-keeping compartment, and a freezer, depending on the temperature settings of the compartments, for storing items requiring different storage temperatures. The drawer assembly provided in this embodiment may be disposed within one or more of the compartments, and each compartment may also be provided with one or more drawer assemblies for storing items.

[0025] like Figures 1 to 3 As shown, the drawer assembly includes: a drawer body, a drawer outer box 1, a slide rail assembly 2, an electronic assembly 3 and a wiring harness 4 electrically connected to the electronic assembly 3.

[0026] The drawer outer box 1 includes a receiving cavity 11 and at least one opening 12 . The drawer body is movably disposed in the receiving cavity 11 through the slide rail assembly 2 and moves in and out along the opening 12 .

[0027] In this embodiment, the drawer assembly is particularly used in a storage area with oxygen control and freshness preservation functions. The oxygen control and freshness preservation functions have high requirements on the sealing of the drawer. Therefore, a drawer outer box 1 is provided on the outside of the drawer body, which is used to seal the drawer body when the drawer is completely inserted into the drawer outer box 1, thereby minimizing the circulation of air and maintaining the stability of the storage environment.

[0028] Furthermore, in this embodiment, the drawer outer box 1 is a split-type structural design, including an outer box upper cover 1a and an outer box lower cover 1b. When the outer box upper cover 1a and the outer box lower cover 1b are closed, the space between them constitutes a storage cavity 11 and an opening 12 facing the user. The drawer body is placed in the storage cavity 11, and the user pushes and pulls the drawer to move it in and out along the opening 12 to take items in and out. The outer box upper cover 1a and the outer box lower cover 1b can be fixed with other modular components for achieving oxygen control and freshness preservation, such as a control module arranged on the top side of the outer box upper cover 1a and a sealing strip arranged around the opening 12.

[0029] The slide rail assembly 2 is arranged on one side of the accommodating cavity 11, and the drawer body moves in and out along the opening 12 through the slide rail assembly 2. The slide rail assembly 2 can be a linear bearing, a pulley structure, or a telescopic pulley structure, etc. In this embodiment, the slide rail assembly 2 realizes the movement of the drawer body through the drag chain 21. Through the drag chain 21, the movement of the drawer body along the slide rail becomes smoother, reducing the vibration and noise that may be generated during the movement. The use of the drag chain 21 as the movement trajectory control structure in the slide rail assembly enhances the durability of the entire system and extends the service life of the drawer. The slide rail assembly 2 using the drag chain 21 allows for more flexible configuration and customization, and can be optimized according to the space size of different models of refrigerators.

[0030] Furthermore, the rail assembly 2 includes a rail housing 22 that extends along the depth of the accommodating cavity 11. The drag chain 21 is housed within the rail housing 22. When cleaning or repair is required, the entire system can be cleaned or disassembled, facilitating long-term maintenance and repair, ensuring the long-term performance of the drawer system. The rail housing 22 effectively encloses the moving parts between the drawer body and the rail assembly 2, protecting the drag chain 21 structure and reducing the risk of user contact with moving parts during operation.

[0031] Specifically, in this embodiment, the slide rail assembly 2 is disposed at the bottom of one side of the storage space. Positioned in the bottom side area, the slide rail assembly 2 minimizes interference with the storage space while ensuring stable and smooth drawer movement. The design of the bottom slide rail assembly 2 provides sturdy support and a precise guide path for the drawer body, ensuring smooth and unobstructed opening and closing, even with heavy items inside. The drawer body naturally rests on the slide rail assembly 2, effectively preventing the drawer from shaking or derailing during movement.

[0032] The end of the drag chain 21 is fixedly set on the lower cover 1b of the outer box body. After extending inward, it bends and extends outward. The inner side is the side away from the user when the user faces the refrigerator, and the outer side is the side facing the user. The drag chain 21 includes an end fixedly set on the lower cover 1b of the outer box body and a starting end facing outward.

[0033] In this embodiment, the drawer assembly is provided with an electronic assembly 3, and the wiring harness 4 of the electronic assembly 3 is arranged along the rail assembly 2. The electronic assembly 3 may include a temperature sensor, a humidity sensor, a lighting device (such as an LED lamp), an intelligent control module, etc. The electronic assembly 3 can realize functions such as temperature and humidity monitoring, automatic adjustment, internal lighting and intelligent interconnection. In order to realize the functions of the electronic assembly 3, it is necessary to electrically connect the electronic device with a power supply device through the wiring harness 4. Since the drag chain 21 occupies less space in the rail assembly 2, the wiring harness 4 of the electronic assembly 3 can be routed along the rail assembly 2. The design makes full use of the space and avoids the wiring harness 4 from occupying additional drawer space, thereby making the layout of the wiring harness 4 neater. And since the wiring harness 4 is arranged in the rail housing 22, it plays a role in protecting and isolating the wiring harness 4, preventing moisture and pollutants from damaging the electronic assembly 3, and at the same time reducing the risk of damage to the wiring harness 4, ensuring electrical safety during use, and ensuring the stability and safety of the electronic system.

[0034] Furthermore, in this embodiment, the drawer assembly also includes a wire box 5, which is arranged at the end of the drag chain 21. After the wire harness 4 extends along the drag chain 21 to the wire box 5, it bends and extends toward the inner side of the drawer outer box 1. Through the use of the wire box 5, the wire harness 4 is still effectively organized and protected after extending out of the drag chain 21. The wire box 5 is internally designed with a structure for fixing and guiding the wire harness 4 to ensure that the wire harness 4 can remain stable in any state of use, avoiding wear or damage to the wires caused by frequent opening and closing of the drawer. The wire box 5 can also play a protective role, ensuring safety during use. The combination of the wire box 5 and the drag chain 21 system provides greater flexibility for the arrangement of wires, and can adapt to different designs and space requirements, especially the integration of complex electronic systems in a limited space.

[0035] The slide rail assembly 2 not only serves as a structural component to support and guide the movement of the drawer, but also serves as a channel for the wiring harness 4, making full use of the space inside the drawer assembly and increasing the volume that can be stored.

[0036] Furthermore, the electronic components include a display screen mounted on the front panel. The display screen is installed on the front panel of the drawer and can be used to display temperature information, humidity levels, and other related intelligent control options within the refrigerator and drawer. A wiring harness 4 electrically connected to the display screen extends to the starting end of the drag chain 21 and then runs along the drag chain 21. Because the display screen is mounted on the drawer panel, its wiring harness 4 must run from the front to the back of the drawer assembly to connect to the main control system and power supply. This wiring method significantly improves drawer space utilization and wiring efficiency.

[0037] Furthermore, a water storage box is included, which is arranged in the area above the slide rail assembly 2. In other embodiments of the present invention, the water storage box can also be replaced with other unused storage spaces, so that some necessary areas that cannot be used as conventional storage spaces can be concentratedly utilized, further increasing the space utilization rate of the drawer.

[0038] Furthermore, the drawer assembly further includes a magnetic switch 6. The drawer body is provided with a magnet, and the magnetic switch 6 is configured to detect the distance between the magnet and the drawer body.

[0039] When the drawer is closed or opened to a certain position, the distance between the magnet and the magnetic switch 6 changes, thereby triggering the response of the magnetic switch 6. The magnetic switch 6 accurately determines the open or closed state of the drawer by detecting the presence of the magnet and the change in the distance between it and the switch. The use of the magnetic switch 6 simplifies the detection method and improves the accuracy and reliability of the detection. Through the feedback of the magnetic switch 6, the drawer status can be intelligently monitored and connected to the refrigerator control system to achieve intelligent operations such as lighting control and temperature and humidity adjustment. Compared with other detection devices, the magnetic switch 6 has a simple structure, easy maintenance, high durability, and greatly reduces the failure rate and maintenance costs. Even when the Wi-Fi network is unavailable, the magnetic switch 6 can still accurately determine whether the drawer has reached its maximum pull-out stroke. The function independent of the network status ensures the stability and reliability of the device and can still be used in an environment with unstable network connection.

[0040] Furthermore, the electronic component 3 also includes a lighting component 31, which is arranged on the rear side of the drawer outer box 1 and is arranged toward the drawer body.

[0041] Specifically, the lighting assembly 31 includes a light bar 312, a light bar bracket 311 and a lampshade 313. The light bar bracket 311 is fixedly arranged on the inner wall side of the outer box body 1 of the drawer. The light bar bracket 311 and the lampshade 313 are arranged to form a light bar 312 accommodating cavity. The light bar 312 is arranged in the light bar 312 accommodating cavity, and the angle between the light bar 312 and the horizontal direction is set at 60°.

[0042] The light assembly 31 is positioned on the rear side of the drawer's outer housing 1, facing the drawer itself. This ensures direct light exposure to the drawer interior, ensuring good visibility of the contents regardless of the drawer's position. The light bar bracket 311 is fixed to the inner wall of the drawer's outer housing 1 via a snap-fit ​​design. The design of the light bar bracket 311 balances stability with ease of installation, ensuring the durability and maintenance of the light assembly 31.

[0043] The installation angle of the light strip 312 in the light strip 312 accommodating cavity is set to 60° with the horizontal direction. This angle setting takes into account the optimal lighting effect and light coverage range, and can ensure that the light is evenly distributed inside the drawer, so that both the front and rear ends of the storage area can be adequately illuminated.

[0044] Through the cooperation of the magnetic switch 6 and the light assembly 31, when the magnetic switch 6 detects that the drawer has been pulled out to its maximum stroke, it controls the light assembly 31 to turn on through the control module, ensuring that even the ingredients in the deepest part of the drawer can be adequately illuminated. In some embodiments, a camera is also provided in the top area of ​​the drawer. Sufficient fill light intensity reduces the impact on imaging quality caused by insufficient light or mutual obstruction of stored items. Even in a dimly lit environment, the camera can capture clear and bright images of ingredients and provide accurate visual information. In addition to improving imaging quality, the light assembly 31 also has the function of local lighting for taking items. When users access items in the deepest part of the drawer, they can more easily identify and take the ingredients they need, which improves the convenience of use.

[0045] In summary, this embodiment provides a refrigerator, which includes a drawer assembly provided with a slide rail system, and the drawer assembly is provided with electronic devices such as display screens. The wiring harness 4 of the electronic device is arranged along the slide rail assembly 2, which effectively increases the utilization space of the drawer while maintaining the simplicity of the drawer body structure, thereby improving the overall space utilization while ensuring safety.
