[0023] AsFigures 1 to 7 The utility model discloses a refrigerator with independent space sterilization, agricultural residue reduction and moisture preservation, which adopts the technical scheme of comprising a box body 1 and a fan, a refrigeration air duct 101 is formed in the rear wall of the box body 1, the refrigeration air duct 101 is connected with the fan, the fan can blow the cold air generated by the refrigerator evaporator into the refrigeration air duct 101, and a control module on the refrigerator is electrically connected with the fan. An air duct air outlet 102 is formed in the box body 1, the refrigeration air duct 101 is connected with the inside of the box body 1 through the air duct air outlet 102. A return air inlet is also formed in the box body 1, the return air inlet is connected with a return air duct, the cold air blown into the box body 1 enters the return air duct through the return air inlet to form a circulation at the evaporator. A drawer 2 is slidably connected in the box body 1.

[0024] A sterilization and moisture preservation assembly 3 is arranged above the drawer 2, and the two sides of the sterilization and moisture preservation assembly 3 are connected with the inner wall of the box body 1. Figures 5 to 7As shown, the main body of the sterilization and moisture retention assembly 3 is a mounting plate 302, which is connected to the inner wall of the box body 1 on both sides, and a sink is arranged on the mounting plate 302, and the side wall of the sink is provided with an air inlet 301, which corresponds to the position of the air outlet 102 of the air duct, so that the cold air blown out of the air outlet 102 of the air duct can be blown into the sink from the air inlet 301. In order to enable the cold air to enter the drawer 2, a sterilization air outlet 305 is arranged on the bottom surface of the sink, which connects the sink with the internal space of the drawer 2 below the sterilization and moisture retention assembly 3. In order to be able to sterilize and reduce the agricultural residues of the food in the drawer 2, a sterilization box module 303 is installed in the sink, and a negative ion generator and an ultraviolet lamp are arranged in the shell of the sterilization box module 303. The negative ion generator can generate negative ions, and the ultraviolet lamp can convert part of the oxygen in the surrounding environment into ozone by irradiation. In order to be able to drive the ultraviolet lamp, an ultraviolet lamp driving module 304 is also installed in the sink, which is electrically connected with the ultraviolet lamp, and the ultraviolet lamp driving module 304 and the negative ion generator are electrically connected with the control module of the refrigerator. In order to be able to bring the negative ions and ozone generated in the sterilization box module 303 into the drawer 2 to sterilize and reduce the agricultural residues of the food, ventilation holes are arranged on the shell of the sterilization box module 303, so that the cold air flowing into the sink can blow through the sterilization box module 303 through the ventilation holes to blow out the negative ions and ozone. In order to enable the negative ions and ozone to smoothly enter the drawer 2, the sterilization box module 303 should also be located in the upwind direction of the sterilization air outlet 305, so a airflow guiding structure is arranged on the sink, which is a guide slope, the air inlet 301 is opposite to the guide slope, and the sterilization box module 303 is located at the end of the guide slope. After the cold air enters the air inlet 301, it blows to the sterilization box module 303 under the guidance of the guide slope, passes through the ventilation holes on the sterilization box module 303, blows out the negative ions and ozone generated in the sterilization box module 303, and blows into the drawer 2 through the sterilization air outlet 305, to sterilize and reduce the agricultural residues of the food in the drawer 2. A top sealing plate is arranged on the top surface of the mounting plate 302 to close the sink from above. The bottom surface of the top sealing plate is a mirror surface, which can reflect the ultraviolet light emitted by the ultraviolet lamp in the sterilization box module 303, and part of the reflected light can pass through the gap of the sterilization air outlet 305 to irradiate the food in the drawer 2, to sterilize and reduce the agricultural residues of the food. However, due to the limitation of the reflected ultraviolet light, this is only an auxiliary means.

[0025] In order to realize the circulation of the cold air flow, the mounting plate 302 is arranged in an L-shaped structure, and a circulating air inlet 307 is arranged on the vertical plate thereof, Figure 7As shown, the cold air flow into the drawer 2 can flow to the drawer 2 and the box body 1 through the circulating air port 307, and then return through the return air port, in order to reduce the moisture loss in the drawer 2, the humidifying module 306 is installed outside the circulating air port 307, the humidifying module 306 relies on the principle of the humidifying film to block the moisture in the passing cold air to achieve the effect of humidification.

[0026] In order to prevent the cold air passing through the sterilization and humidification assembly 3 and the drawer 2 from overflowing from the joint between the sterilization and humidification assembly 3 and the drawer 2, a sealing gasket is arranged between the mounting plate 302 of the sterilization and humidification assembly 3 and the drawer 2.

[0027] In order to ensure that the air pressure at the air inlet 301 is higher than the air pressure at the circulating air port 307, a guide groove is arranged on the vertical plate of the mounting plate 302, the air inlet 301 is arranged in the guide groove, and a sealing groove is arranged around the slot of the guide groove on the vertical plate. A square ring-shaped sealing ring is arranged in the sealing groove, the square ring-shaped sealing ring can seal the gap between the air duct outlet 102 and the guide groove, so that the cold air blown out of the air duct outlet 102 can enter the air inlet 301.

[0028] The working principle of the utility model is as follows:

[0029] The control module controls the negative ion generator in the sterilization box module 303 to generate negative ions, and controls the ultraviolet lamp driving module 304 to start the ultraviolet lamp in the sterilization box module 303 to irradiate, so as to convert part of the oxygen around into ozone.

[0030] The cold air in the refrigeration air duct 101 is blown out of the air duct outlet 102, due to the sealing of the sealing ring, all the cold air blown out of the air duct outlet 102 enters the sink groove of the mounting plate 302 through the air inlet 301 in the guide groove of the sterilization and humidification assembly 3, and does not overflow under the cover of the top cover plate; the cold air flow entering the sink groove is guided to the sterilization box module 303 under the guidance of the air flow guide structure, and the negative ions and ozone generated by the sterilization box module 303 are blown out after passing through the ventilation hole on the shell of the sterilization box module 303, and are blown into the drawer 2 through the sterilization air outlet 305, so as to sterilize and reduce the pesticide residues in the drawer 2. When the cold air flow entering the drawer 2 leaves the drawer 2 through the circulating air port 307, the moisture is blocked by the humidifying module 306 to prevent the moisture in the drawer 2 from being lost. The dry cold air passing through the humidifying module 306 enters between the drawer 2 and the box body 1, and then enters the return air duct through the return air port.

[0031] The circuit and mechanical connection are the common means adopted by the person skilled in the art, and the technical inspiration can be obtained through limited tests, and belong to the common general knowledge.
