Abstract

The invention discloses a fruit-vegetable box applicable to an air-cooling refrigerator. The fruit-vegetable box comprises a box body, wherein a spraying device is arranged at the top in the box body; an air inlet is arranged at the upper part of the front side of the box body; an air outlet is backwards and convexly arranged at the lower part of the rear side of the box body and is communicated with an air duct of the refrigerator; the tops of the rear ends of the air inlet and the air outlet are respectively hinged with a wind board; and the wind boards are used for blocking the air inlet and the air outlet. The invention also discloses a rapid-cooling and moisturizing method of the fruit-vegetable box applicable to the air-cooling refrigerator. The fruit-vegetable box is provided with the air outlet connected with the air duct of the refrigerator, so that high-humidity gas in the fruit-vegetable box is directly conveyed out by the air duct of the refrigerator, and is prevented from entering a refrigerating chamber and further promoting the frosting phenomenon in the refrigerating chamber. The spraying device can carry out spraying and over-humidifying treatment on fruits and vegetables in advance, the circulating air of the refrigerator can carry out evaporation and cooling on the fruits and the vegetables, so that not only is rapid cooling of the fruits and the vegetables realized, but also high humidity of the fruits and the vegetables is maintained, and simultaneously, the frosting phenomenon in the refrigerating room can not be promoted.

Description

technical field

[0001] The invention relates to the technical field of fruit and vegetable preservation, in particular to a fruit and vegetable box for an air-cooled refrigerator and a quick cooling and moisturizing method thereof. Background technique

[0002] Postharvest physiology believes that due to the high water content in fruits and vegetables, the humidity is often close to saturation, so the evaporation of water depends on the temperature and relative humidity of the product and the environment. The higher the temperature, the greater the water pressure difference inside and outside the fruits and vegetables, and the faster the water evaporates. Therefore, air-cooled refrigerators that use forced convection circulating air to achieve rapid cooling are popular, but circulating air will cause stored foods (especially fruits and vegetables) to lose moisture very easily. Simultaneously cooling fruits and vegetables (or other foods) rapidly and maintaining high humidit...

Examples

Embodiment 1

[0028] Such as Figure 1 to Figure 3 shown ( figure 1 The direction shown by the middle arrow is the airflow direction), the fruit and vegetable box suitable for air-cooled refrigerators of the present invention includes a box body 2, and the top of the box body 2 is provided with a spray device 1, and the front side of the box body 2 (the present invention Among them, the side facing the user is referred to as the front side) and the upper part is provided with an air inlet 3, and the lower part of the rear side of the box body 2 is provided with an air outlet 7 protruding backward, and the air outlet 7 extends into the refrigerator air duct 8 The way is connected with refrigerator air duct 8; the top of the rear end of the air inlet 3 and the air outlet 7 can be disassembled and hinged with a windshield 12 made of plastic; the windshield 12 is used to block all The air inlet 3 and the air outlet 7.

[0029] Described box body 2 is provided with movable shelf at the bottom,...

Embodiment 2

[0038] The difference between the present embodiment and the first embodiment lies in the quick cooling and moisturizing method.

[0039] An air duct 8 is provided in the cabinet 6 of the air-cooled refrigerator using a fruit and vegetable box, and a fan 9 is provided in the air duct 8; the fan 9 is connected with the electric control device of the refrigerator, and the electric control device of the refrigerator includes a spray timing control (the timing controller is a mature prior art, not shown in the figure).

[0040] The first step of the quick cooling and moisturizing method of this embodiment is that the spraying device 1 starts to spray and over-humidify the box body 2; the spray over-humidification refers to spraying into the box body 2 until the relative humidity in the box body 2 more than 100%; during this process, the spray is vaporized in the box body 2, thereby rapidly reducing the temperature in the box body 2; the spray humidification process forms cold wate...
