[0028] Please refer to Figures 1 to 3 The present application provides a refrigerator drawer 100, which comprises a drawer body 10, a lighting assembly 20 and a plurality of baffles 30. The drawer body 10 has a containing space 11. The plurality of baffles 30 are movably arranged in the containing space 11 to divide the containing space 11 into a plurality of compartments 111. The relative sizes of the plurality of compartments 111 can be adjusted. The lighting assembly 20 is used to irradiate at least one compartment 111. By arranging the baffles 30, the containing space 11 can be divided, thereby facilitating the user to store in different areas. Moreover, the user can move the baffles in the containing space 11 according to the needs, thereby adjusting the relative sizes of the plurality of compartments 111. Since light can promote photosynthesis of plants, by arranging the lighting assembly 20, the lighting assembly 20 can promote photosynthesis of fruits and vegetables placed in the corresponding compartments 111, thereby being beneficial to the preservation of the fruits and vegetables. In actual use, the user can adjust the positions of the baffles 30 according to the needs, so as to increase the relative size of the compartment 111 irradiated by the lighting assembly 20, thereby enabling the compartment 111 to place more fruits and vegetables, thereby preserving more fruits and vegetables.

[0029] As Figure 2As shown, the refrigerator drawer 100 further comprises an oxygen concentration sensor 40, and the compartment 111 defined by the illumination assembly 20 for irradiation is a fresh-keeping space 112. The oxygen concentration sensor 40 is configured to detect the oxygen concentration value of the fresh-keeping space 112. It can be understood that oxygen is the product of respiration of fruits and vegetables and the raw material of photosynthesis of fruits and vegetables. Therefore, in order to keep the fruits and vegetables in the fresh-keeping space 112 in a fresh state, the oxygen concentration value in the fresh-keeping space 112 needs to be within a suitable range, and the oxygen level in the fresh-keeping space 112 can be monitored by the oxygen concentration sensor 40.

[0030] Further, the illumination intensity of the illumination assembly 20 is adjustable, and the illumination assembly 20 is configured to adjust the illumination intensity and the illumination time according to the oxygen concentration value detected by the oxygen concentration sensor 40. It can be understood that the illumination intensity and the illumination time are also important factors affecting the photosynthesis and respiration of fruits and vegetables. By matching the oxygen concentration value in the fresh-keeping space 112 with the illumination intensity, the level of photosynthesis of fruits and vegetables is reached, so that the fruits and vegetables in the fresh-keeping space 112 can continue to grow under suitable illumination conditions, thereby achieving the effect of preservation.

[0031] Specifically, the matching relationship between the oxygen concentration value in the fresh-keeping space 112 and the illumination intensity is that as the oxygen concentration value in the fresh-keeping space 112 detected by the oxygen concentration sensor 40 decreases, the illumination intensity of the illumination assembly 20 increases. It can be understood that as the photosynthesis of fruits and vegetables in the fresh-keeping space 112 proceeds, the oxygen in the fresh-keeping space 112 is consumed, thereby reducing the oxygen concentration in the fresh-keeping space 112. A low-oxygen environment can inhibit the respiration of fruits and vegetables, thereby reducing the consumption of organic matter such as sugar. At this time, increasing the illumination intensity of the illumination assembly 20 in a low-oxygen environment can improve the photosynthesis of plants while the low-oxygen environment can effectively reduce the negative effects of increased stomatal opening and accelerated respiration of fruits and vegetables caused by illumination. Thus, the preservation of improved photosynthesis and low-oxygen preservation can be achieved.

[0032] Further, when the oxygen concentration in the fresh-keeping space 112 decreases to a preset concentration value, the illumination assembly 20 operates at the current illumination intensity for a period of time and then turns off. In this way, the deterioration of fruits and vegetables caused by long illumination time can be avoided.

[0033] As Figure 3As shown, the refrigerator drawer 100 further comprises a light intensity sensor 50 for detecting the light intensity value of the preservation space 112, and a control unit. The lighting assembly 20, the oxygen concentration sensor 40 and the light intensity sensor 50 are respectively connected to the control unit. The light intensity sensor 50 transmits the detected light intensity value of the preservation space 112 to the control unit, the oxygen concentration sensor 40 transmits the detected oxygen concentration value of the preservation space 112 to the control unit, and the control unit adjusts the light intensity of the lighting assembly 20.

[0034] As shown in Figures 2 to 5 The inner wall of the accommodation space 11 is provided with a track 113 extending along the length direction X of the drawer body 10, and a plurality of baffles 30 are arranged along the extension direction of the track 113 and are respectively slidingly connected to the track 113.

[0035] Among them, the track 113 is configured as two groups, and the two groups of tracks 113 are respectively arranged on the inner walls of the two sides of the accommodation space 11 along the width direction Y of the drawer body 10.

[0036] Optionally, in an embodiment, as shown in Figure 5 The track 113 is configured as a rack 114, and the end of each baffle 30 is rotatably connected with a gear 31, and the gear 31 is engaged with the rack 114. By engaging the gear 31 with the rack 114, the baffle 30 can slide more stably in the accommodation space 11. Specifically, the side wall of the drawer body protrudes outwardly and forms a groove 12 communicating with the accommodation space 11, and the rack is arranged in the groove 12, and the gear 31 is accommodated in the groove 12.

[0037] Further, each group of tracks 113 comprises two racks 114, and the two racks 114 are spaced apart along the height direction Z of the drawer body 10. The gear 31 and the rack 114 are arranged one by one.

[0038] In other embodiments, the track 113 can also be configured as a sliding groove, and a sliding block (not shown) is arranged at the end of the baffle 30, and the sliding block is slidingly clamped in the sliding groove to achieve the sliding connection of the baffle 30 to the track 113.

[0039] Exemplarily, as shown in Figure 2 and Figure 3As shown, in an embodiment, the number of baffles 30 is configured as two, the two baffles 30 are arranged along the extension direction of the track 113, and divide the accommodation space 11 into three compartments 111, wherein the middle compartment 111 is configured as the fresh-keeping space 112, and the oxygen concentration sensor 40 and the light intensity sensor 50 are respectively installed on the wall surfaces of the two baffles 30 facing each other. In this way, by moving the two baffles 30 along the extension direction of the track 113 respectively, the relative sizes of the three compartments 111 can be adjusted. By respectively installing the oxygen concentration sensor 40 and the light intensity sensor 50 on the wall surfaces of the two baffles 30 facing each other, not only the assembly of the oxygen concentration sensor 40 and the light intensity sensor 50 is facilitated, but also the oxygen concentration value and the light intensity value of the fresh-keeping space 112 can be more accurately detected. When it is necessary to preserve fruits and vegetables in the fresh-keeping space 112, the two baffles 30 can be moved to the two ends of the track 113 respectively, so as to adjust the capacity of the fresh-keeping space 112 to the maximum.

[0040] As shown in Figure 2 and Figure 3 As shown, the refrigerator drawer 100 further comprises an upper cover 70, the upper cover 70 is arranged at the opening of the drawer main body 10, and the illumination assembly 20 is detachably installed on the upper cover 70.

[0041] One end of each baffle 30 is in sealing cooperation with the bottom wall of the accommodation space 11, and the other end is in sealing cooperation with the upper cover 70. In this way, the three compartments 111 are independent of each other, and each compartment 111 has good sealing performance. Therefore, the oxygen concentration level in the compartment 111 serving as the fresh-keeping space 112 can be more accurately measured.

[0042] Among them, the form of setting a sealing gasket between the baffle 30 and the bottom wall of the accommodation space 11, and between the baffle 30 and the upper cover 70 can be adopted to improve the sealing performance of each compartment 111.

[0043] The upper cover 70 is configured of transparent material, and the side of the upper cover 70 away from the accommodation space 11 is provided with a mounting groove 71, the illumination assembly 20 comprises a surface light source 21 and a cover plate 22, the surface light source 21 is arranged in the mounting groove 71, and the cover plate 22 is detachably connected to the groove wall of the mounting groove 71 and is used to close the mounting groove 71.

[0044] Among them, the bottom wall of the mounting groove 71 is configured as a porous structure communicating with the accommodation space 11. Along the height direction Z of the drawer main body 10, the surface light source 21 is arranged directly above the fresh-keeping space 112, and the refrigerator drawer 100 further comprises a decorative panel 60, the decorative panel 60 is arranged at the front end of the drawer main body 10 along the width direction Y of the drawer main body.

[0045] Please refer to Figure 6The following will take an embodiment as an example to introduce a method for adjusting the light intensity of the lighting assembly 20 according to the light intensity value of the fresh-keeping space 112 detected by the light intensity sensor 50 and the oxygen concentration value of the fresh-keeping space 112 detected by the oxygen concentration sensor 40.

[0046] Step S1, turn on the lighting assembly 20, detect the oxygen concentration value in the fresh-keeping space 112, and detect the light intensity value in the fresh-keeping space 112;

[0047] Step S2, when the oxygen concentration value in the fresh-keeping space 112 is greater than the first oxygen concentration value K1, adjust the lighting assembly 20 to operate at the first light intensity value L1;

[0048] Step S3, when the oxygen concentration value in the fresh-keeping space 112 is between the first oxygen concentration value K1 and the second oxygen concentration value K2, adjust the lighting assembly 20 to operate at the second light intensity value L2;

[0049] Step S4, when the oxygen concentration value in the fresh-keeping space 112 is less than the second oxygen concentration value K2, adjust the lighting assembly 20 to operate at the third light intensity value L3, and turn off the lighting assembly 20 after operating at the third light intensity value L3 for a preset time T. Wherein, the first oxygen concentration value K1 > the second oxygen concentration value K2; the first light intensity value L1 < the second light intensity value L2 < the third light intensity value L3.
