[0027] This utility model provides a refrigerator drawer 100 that can adjust the color and duration of light emitted by the light-emitting unit 31 according to the color of the stored food, thereby promoting the photosynthesis of vegetables and fruits inside the drawer and thus achieving the preservation of vegetables and fruits inside the drawer.
[0028] Please see Figures 1-3 The refrigerator drawer 100 includes a main body 10, a cover 20, and a preservation component 30. The main body 10 has a cavity inside, and an opening communicating with the cavity is provided on the main body 10. The cavity is used to accommodate food to be preserved. The cover 20 covers the opening. The preservation component 30 is located in the cavity and is connected to the cover 20. The preservation component 30 includes a light-emitting unit 31, a vision unit 32, and a controller. The light-emitting unit 31 can emit light of various colors. The vision unit 32 can identify and collect the color of the food to be preserved. The controller is electrically connected to the light-emitting unit 31 and the vision unit 32 and is configured to control the color of the light emitted by the light-emitting unit 31 in response to the electrical signal of the vision unit 32.
[0029] In this way, the vision unit 32 acquires the type and color of the food to be preserved stored in the cavity and transmits this information to the controller through an electrical signal. The controller then determines the color and duration of the light emitted by the light-emitting unit 31, thereby promoting the photosynthesis of vegetables and fruits inside the drawer and thus achieving the preservation status of vegetables and fruits inside the drawer.
[0030] It should be explained that the food to be preserved is usually fruits and vegetables of various colors. In this embodiment, the light emitted by the light-emitting unit 31 is set to red, white, blue, purple, and green light, thus adapting to most types of fruits and vegetables. The light-emitting unit 31 is equipped with LEDs, including LEDs that can emit red light, LEDs that can emit white light, and so on. The controller can control the LEDs of different colors to emit light according to the different colors of fruits and vegetables.
[0031] The light-emitting unit 31 includes a mounting box 311 and a light-emitting element 312. The mounting box 311 and the cover plate 20 cooperate to form a receiving cavity, and the light-emitting element 312 is installed in the receiving cavity. In this way, the mounting box 311 can facilitate the assembly of the light-emitting element 312, and the light-emitting element 312 can be installed in the mounting box 311 first and then installed into the cavity.
[0032] Of course, in other embodiments, the light-emitting element 312 can also be directly connected to the cover plate 20.
[0033] The mounting box 311 is made of transparent material, allowing the light emitted by the light-emitting element 312 to propagate smoothly into the cavity. It should be noted that transparent material refers to a material that allows light to pass through. Preferably, the light transmittance of the mounting box 311 is above 50%.
[0034] Understandably, in other embodiments, light-transmitting grooves may also be formed on the mounting box 311 to allow light to propagate. Alternatively, the mounting box 311 may be partially made of a light-transmitting material, and is not limited to the entire mounting box 311 being made of a light-transmitting material as described above.
[0035] The mounting box 311 has a receiving groove 3111. The opening of the receiving groove 3111 is connected to the side of the cover plate 20 facing the cavity, forming a receiving cavity. The light-emitting element 312 is connected to the groove wall of the receiving groove 3111. In this way, a receiving space for the light-emitting element 312 is formed.
[0036] Furthermore, the cover plate 20 has multiple first latches 21 on its inner wall facing the chamber, and the first latches 21 engage with the mounting box 311. In this way, the first latches 21 can improve the connection strength between the cover plate 20 and the mounting box 311 and facilitate disassembly.
[0037] In other embodiments, the cover plate 20 and the mounting box 311 may also be connected together by processes such as welding or bonding.
[0038] Furthermore, both ends of the mounting box 311 along its length are engaged with at least one first latch 21, and both sides of the mounting box 311 along its width are engaged with at least two first latches 21. This further strengthens the connection between the mounting box 311 and the cover plate 20. Please refer to... Figure 2 The mounting box 311 is limited on both sides in the width direction by its longer side, so the longer side needs to have more first claws 21 to strengthen the connection. This prevents the mounting box 311 from falling off during the vibration of the refrigerator drawer 100 during long-term operation.
[0039] The bottom of the receiving groove 3111, away from the cover plate 20, has multiple second claws 313 that engage with the light-emitting element 312. Thus, as described above, the second claws 313 strengthen the connection between the light-emitting element 312 and the mounting box 311.
[0040] In this embodiment, the light-emitting element 312 is set as a light strip, and the light strip is arranged along the length of the mounting box 311, thereby emitting more uniform light. The propagation of the light is also more adapted to the shape of the mounting box 311, and is more suitable for the shape of the rectangular mounting box 311.
[0041] The vision unit 32 includes a camera 321 and a base 322. The base 322 is constructed on the side of the cover plate 20 facing the chamber. A connecting groove is provided in the base 322, and the camera 321 is installed in the connecting groove.
[0042] In this embodiment, camera 321 is a miniature camera. Camera 321 records the types and states of vegetables and fruits placed inside the drawer. This information is fed back to the controller as data storage and also sends a signal to the controller to control the opening and closing of the LED light strip. The controller has a pre-established database of basic information about vegetables and fruits. It receives the types and states of vegetables and fruits recorded by the miniature camera, stores and compares the data, and simultaneously controls the opening and closing of the multi-color LED lights.
[0043] In the operation of this invention, when the refrigerator is running normally, the user places vegetables and fruits into the refrigerator drawer 100. The user can activate the preservation function via the control panel buttons on the refrigerator. At this time, the camera 321 records the type and state of the placed vegetables and fruits and sends a feedback signal to the controller. The controller stores the data and compares it with pre-established database information. Then, it controls the multi-color LED lights to turn on their specific color illumination, which promotes photosynthesis in the vegetables and fruits inside the drawer, thus achieving a preservation effect. During the operation of the light preservation function inside the drawer, the camera 321 records and feeds back data in real time. The controller receives and controls the color and illumination duration of the multi-color LED lights in real time, thereby ensuring good photosynthesis of the vegetables and fruits inside the drawer and preventing damage to their food state due to excessive photosynthesis.
[0044] This utility model also provides a refrigerator, including the refrigerator drawer 100 as described above.
[0045] Compared to existing technologies, this invention uses a vision unit 32 to acquire the type and color of the food to be preserved stored in the cavity, and transmits this information to a controller via an electrical signal. The controller then determines the color and duration of the light emitted by the light-emitting unit 31, thereby promoting the photosynthesis of vegetables and fruits inside the drawer and thus achieving the preservation of vegetables and fruits inside the drawer.
[0046] 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.
[0047] 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.
