Embodiment 1

[0061]In this embodiment, in the fruit freshening mode and the vegetable freshening mode, the first light source, the second light source and the third light source operate independently in sequence in the same cycle, and the first light source runs for the longest time, that is, the first light source It runs first, the second light source runs after it goes out, and the third light source runs after the second light source goes out. In this embodiment, the operating rules of the first light source, the second light source and the third light source in the same cycle under different freshness-increasing modes are shown in Table 1 below.

[0062]

[0063] As shown in Table 1, in the fruit freshening mode, in the same cycle, the first light source runs for 5s-8s first, then goes out for 1s, then the second light source runs for 1s, then goes out for 1s, the third light source runs for 1s-3s, and then goes out After 1 second, the next operation cycle is performed according to...

Embodiment 2

[0067] In this embodiment, the first light source, the second light source and the third light source operate simultaneously in the same period in both the fruit freshness increasing mode and the vegetable freshening mode, and the first light source runs for the longest time. In this embodiment, the operation rules of the first light source, the second light source and the third light source in the same period under different freshness increasing modes are shown in Table 2 below.

[0068]

[0069] As shown in Table 2, in the fruit freshening mode, within the same cycle, the first light source, the second light source and the third light source operate simultaneously, wherein the first light source operates for 5s-8s, the second light source operates for 1s, and the third light source operates 1s-3s, the second light source and the third light source are extinguished first, and the first light source with the longest running time is also extinguished and after 1s, the three l...

Embodiment 3

[0072] refer to Figure 9 and Figure 10 In this embodiment, the light preservation device 300 further includes a sterilizing module 330 capable of emitting ultraviolet light waves for sterilizing the surface of food in the refrigerator compartment 130 . The sterilizing module 330 can emit ultraviolet light in a specific band. Due to the poor penetrating ability of ultraviolet light waves, the light loss after it penetrates the light guide plate 311 is large, so the sterilizing module 330 can be installed separately, such as integrating LED lamp beads that can generate ultraviolet light waves On another circuit board, the LED lamp beads that generate ultraviolet light waves do not need to face the light-incident surface 311A ​​of the light guide plate 311 to form a surface light source, so their installation positions are flexible, and can be installed on the refrigerator liner 120 or assembled with the freshness-increasing module 310 as one.

Abstract

The invention provides a refrigerator. The refrigerator comprises a refrigeration liner, and a light fresh keeping device, wherein the light fresh keeping device comprises a fresh increasing module; the fresh increasing module comprises a light guiding plate and a plurality of light sources; the light guiding plate is located on light paths of the light sources; the wavelengths of lights emitted by the light sources are different; the light sources comprise a first light source which can emit red light, a second light source which can emit orange light and a third light source which can emit blue light; the light fresh keeping device has a fresh increasing pattern; the fresh increasing pattern comprises a fruit fresh increasing pattern and a vegetable fresh increasing pattern; under the fruit fresh increasing pattern, in the same period, at least the first light source of the first light source, the second light source and the third light source operates; and under the vegetable freshincreasing pattern, in the same period, at least the third light source of the first light source, the second light source and the third light source operates. Through setting corresponding fresh increasing patterns, a user can select different fresh keeping patterns according to the stored food kinds, and the light fresh keeping effect is further increased.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator with the function of keeping light fresh. Background technique [0002] With the acceleration of the pace of life and changes in consumption habits, many consumers have gradually formed the consumption habit of buying a large amount of food in supermarkets at one time. In order to prolong the storage time of food, they usually store food in the refrigerator, which stores fresh fruits and Vegetables are the most common. [0003] Fresh fruits and vegetables are still fresh living individuals for a long period of time after they are picked. When they are stored in the refrigerator, although the low temperature environment of the refrigerator can inhibit their respiration and slow down metabolism to a certain extent, their own nutrients will be withered. The prolongation of storage time leads to continuous consumption and loss. Therefore, most refrigerator companies are committed to...
