Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a light preservation coupled purification structure applied in a refrigerator. Background Technology

[0002] With the progress of the times and technological innovation, the demand for a healthy lifestyle is becoming increasingly strong. The quality of healthy ingredients is receiving more and more attention, and the storage of some high-end ingredients requires matching preservation technologies. Studies have shown that fruits and vegetables undergo certain beneficial changes under light conditions during post-harvest storage. Light continues photosynthesis, affecting the absorption rate and ethylene release of fruits and vegetables, and inhibiting the growth of microorganisms on the surface of fruits and vegetables.

[0003] Research indicates that the market currently utilizes two main technologies: light-based preservation and photocatalysis. Light-based preservation involves irradiating fruits and vegetables with LED lights, while photocatalysis uses simple LED lights to irradiate catalytic materials. Both technologies rely on the function of the LED lights but differ in their underlying technology. However, light-based preservation suffers from drawbacks such as difficulty in controlling light intensity and wavelength, susceptibility to nutrient loss, and higher costs. Conversely, photocatalysis is susceptible to light exposure, exhibits low degradation efficiency, unstable catalytic performance, and limited effectiveness.

[0004] Based on the above problems, this utility model proposes a light preservation coupled purification structure for use in refrigerators, which effectively combines light preservation technology or photocatalytic technology, reduces component costs, improves the preservation effect of refrigerators, and expands the application of LED lights in refrigerator preservation technology. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a light preservation coupling purification structure for use in refrigerators, the specific technical solution of which is as follows:

[0008] Preferably, the middle area of ​​the photocatalytic component has a reserved structural space for installing LED lights.

[0009] Preferably, the catalytic material is made by spraying titanium dioxide nanomaterials onto the surface of non-woven fabric, textile fiber, or sponge material and then air-drying it.

[0011] Preferably, the LED lights located in the cold storage room are respectively red light lamps, ultraviolet lamps, blue light lamps and white light lamps with a power of 0.1-5W.

[0012] Preferably, the wavelength of the red light is 660nm; and the wavelength of the blue light is 420-450nm.

[0013] More preferably, the size of the photocatalytic component is 10cm*10cm*0.5cm to 20*20*2cm.

[0014] Furthermore, preferably, the dimensions of the cabin are 12cm*12cm*1cm to 25cm*25cm*5cm.

[0015] More preferably, all of the LED lights are electrically connected to the refrigerator's controller.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model, by setting up a photocatalytic component and LED lights of different colors, can turn on the corresponding color LED lights for illumination according to different types and needs of food, thereby realizing photo-preservation technology or photocatalytic purification technology or a combination of the two.

[0018] 2.

[0025] The specific implementation of a light preservation coupling purification structure for use in a refrigerator, provided by this utility model, will be further described in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 As shown, a light-based preservation and purification structure for use in a refrigerator is installed in the refrigerator compartment 1 and storage drawer 2. Specifically, it includes several LED lights 3 and a photocatalytic catalyst component 4. Preferably, to facilitate the entry of light from the refrigerator compartment 1 into the storage drawer 2, a hollow and transparent chamber 5 with dimensions ranging from 12cm*12cm*1cm to 25cm*25cm*5cm is provided at the top of the storage drawer 2. The photocatalytic catalyst component 4 is placed inside the chamber 5. The bottom plate of the chamber 5 has several interactive holes communicating with the inner cavity of the storage drawer 2, ensuring that the negative ions generated by the catalytic material can smoothly enter the inner cavity of the storage drawer 2 and achieve the effects of eliminating odors and sterilizing. The LED lights are respectively located on both sides of the inner liner of the refrigerator compartment 1 near the top and inside the photocatalytic catalyst component 4.

[0027] like Figure 2 As shown, the photocatalytic component 4 includes a frame 41, within which catalytic material 42 and transparent, light-transmitting PVC material 43 are sequentially intercalated from left to right. The dimensions of the photocatalytic component are 10cm*10cm*0.5cm to 20*20*2cm. The catalytic material 42 is made by spraying titanium dioxide nanomaterials onto the surface of non-woven fabric, textile fibers, or sponge material and then air-drying it. As a semiconductor oxide, when bombarded by high-energy ultraviolet photons, electrons transition from the ground state to the excited state, generating high-energy free electrons (e-) and holes (h+). These high-energy free electrons react with water or oxygen molecules to form hydroxyl radicals (·OH) and other oxygen-active groups (such as O2·, HO2·, and H2O2). These groups possess extremely strong oxidizing capabilities, degrading organic pollutants, killing bacteria, mold, and viruses, and simultaneously releasing negative oxygen ions, further eliminating odors.

[0028] Preferably, the middle area of ​​the photocatalytic component 4 is also reserved for the installation of LED lights 3.

[0029] It is worth noting that the LEDs 3 located within the structural clearance area are red, blue, and white light lamps with a power of 0.1-5W, respectively. The LEDs 3 located within the refrigerator compartment are red, ultraviolet, blue, and white light lamps with a power of 0.1-5W, respectively. Preferably, the wavelength of the red light is 660nm; the wavelength of the blue light is 420-450nm.

[0030] More preferably, all of the LED lights 3 are electrically connected to the refrigerator's controller. During use, the user can select different modes for light preservation based on the type of food being stored: when storing green vegetables, the photosynthesis mode is activated, i.e., the red, white, and blue LED lights are turned on; when storing fruits or foods with odors, the catalytic or purification (photocatalytic) mode is activated, i.e., the ultraviolet light is turned on to promote the decomposition of negative ions by the catalytic material to remove odors and sterilize; when storing mixed foods, the mixed mode can be selected for comprehensive preservation. The specific activation time and operating cycle of each mode are as follows: Figure 3 As shown.

[0031] This invention implements light-based preservation technology (i.e., photosynthesis) in the refrigerator compartment and storage drawers, simultaneously combining light-based preservation and photocatalytic technologies within the storage drawers. After being irradiated by LEDs of different colors, the food undergoes photosynthesis, and the negative ions generated by the photocatalytic titanium dioxide material can purify odors from the food, improving the refrigerator's preservation effect. It effectively solves the problems of low degradation efficiency and unstable catalytic performance associated with single-mode light preservation, while allowing for the selection of different modes based on the specific type of food, making it more intelligent.
