By adjusting the movable partition, the size of the breath window area can be changed, so that Adjust the intensity of breathing.

Furthermore, in the fresh-keeping box of the above-mentioned breathing refrigerator, a finger contact piece is provided on the moving partition.

Furthermore, in the fresh-keeping box of the above-mentioned breathing refrigerator, a box cover is installed on the outer end of the storage drawer, and a sealing strip is provided at the corresponding position where the box cover contacts with the fresh-keeping box body.

Still further, in the fresh-keeping box of the breathing refrigerator, corresponding buckles are provided on both sides of the outer end of the storage drawer, and the box cover is buckled connected to the outer end of the fresh-keeping box body.

Adopting the technical scheme of the utility model, relying on the breathing window formed by the silicon rubber film, an appropriate gas ratio can be maintained in the fresh-keeping box during the use of the refrigerator, so that the stored fruits and vegetables can perform proper respiratory metabolism, delay aging, and thus prolong the preservation of fruits and vegetables Expect.

The objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.

Detailed ways

As shown in Figure 1, a breathing refrigerator fresh-keeping box includes a fresh-keeping box body 1, and a storage drawer 2 is arranged in the fresh-keeping box body 1, and its difference is that: the top of the crisper body 1, At least one side has a breathing window. Specifically, in view of a preferred embodiment of the present utility model, the breathing window is provided with a support frame 3 , and the support frame 3 is filled with a silicon rubber film 4 .

Moreover, in order to achieve a better ratio of the concentration of oxygen and carbon dioxide, a guide groove is provided outside the breathing window, and a movable partition 5 is provided in the guide groove. Specifically, the opening degree of the breathing window can be controlled by moving the opening degree of the partition plate 5 . Therefore, it can be adjusted according to the actual situation of the respiration of fruits and vegetables, and the emission ratio of carbon dioxide can be controlled to adapt to different storage requirements. Moreover, in order for the user to conveniently manipulate the movable partition 5 and increase a certain contact area, a finger contact piece 6 is provided on the movable partition 5 .

Furthermore, a box cover 7 is installed on the outer end of the storage drawer 2, and a sealing strip 8 is provided at the contact corresponding position between the box cover 7 and the crisper body 1, so that the storage environment of the crisper body 1 is optimally sealed, Provide better freshness. Considering the convenience of the overall assembly of the utility model, corresponding buckles 9 are provided on both sides of the outer end of the storage drawer 2, and the outer end of the box cover 7 and the fresh-keeping box body 1 is connected by a buckle.

Because fruits and vegetables need respiration, their respiration is mainly affected by several factors such as temperature, oxygen, carbon dioxide concentration and light. Specifically - 1. Temperature, which can significantly affect the rate of plant respiration. The reaction rate of enzymes closely related to the respiration process increases with the increase of temperature within a certain range. However, if the temperature is too high, the enzymes will be denatured and inactivated. Therefore, respiration has its maximum, optimum and minimum temperature ranges. When the temperature is lower than the minimum When the temperature is higher than the maximum temperature, plant respiration stops. 2. The concentration of oxygen and carbon dioxide. Under hypoxic conditions, NADH (nicotinamide adenine dinucleotide) and FADH (protein-binding carrier) of fruits and vegetables are inhibited due to the dehydrogenation and oxidation of the respiratory chain, which hinders the oxidation process in the tricarboxylic acid cycle, so ethanol Fermentation often accounts for a larger proportion. Ethanol is toxic to plants, and at the same time, the supply of ATP and intermediate products of respiration will be insufficient, affecting biosynthesis. Typically, respiration produces marked inhibition of respiration with carbon dioxide concentrations above 5%.

In the actual use of the utility model, the refrigerator provides a lower temperature for the fruits and vegetables, and the function of the silicone rubber film 4 is to organically regulate the gas in the box, and discharge excess carbon dioxide gas, while oxygen cannot enter in large quantities. In the box, the final concentration of carbon dioxide and oxygen reaches a balance state, ensuring the proper breathing of fruits and vegetables stored in the crisper.

It can be seen from the above text description and in conjunction with the accompanying drawings that after the utility model is adopted, the breathing window made of the silicon rubber film 4 can cooperate with the use of the refrigerator to maintain a suitable gas ratio in the fresh-keeping box, so that the fruits and vegetables can be properly dried. Respiratory metabolism, anti-aging, thereby prolonging the freshness period of fruits and vegetables.

Of course, the above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. In addition to the above-mentioned embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
