[0029] As Figures 1 - 4 shown, an embodiment of the present invention provides a fruit and vegetable storage refrigerator, including a refrigerator body 1, and an air outlet 2 is fixed on the side of the inner wall of the refrigerator body 1. The refrigerator further includes:

[0030] The square shell 3 has an air inlet on its side surface. A connecting pipe is fixed to the side surface of the air outlet head 2, and the end of the connecting pipe is fixedly connected to the corresponding air inlet on the side surface of the square shell 3. The connecting pipe is used for connecting the air outlet head 2 and the square shell 3. Inside the square shell 3, there are a first accommodation chamber 31 and a second accommodation chamber 32. A HEPA filter element 4 is fixed in the first accommodation chamber 31. The HEPA filter element 4 is made of polypropylene material and can filter bacteria in the air. On the side of the inner wall of the second accommodation chamber 32 away from the HEPA filter element 4, a plurality of air outlet holes 5 are provided;

[0031] The sterilization component 6 includes an ozone storage tank 61 arranged outside the refrigeration chamber body 1. The ozone storage tank 61 is used for storing ozone. A pipeline 62 is fixed at the air outlet of the ozone storage tank 61. An electromagnetic valve is installed on the pipeline 62. When the electromagnetic valve is opened, ozone can enter the dispersion box 63 through the pipeline 62. When the electromagnetic valve is closed, ozone can be prevented from entering the dispersion box 63. The dispersion box 63 is fixed to the side surface of the square shell 3. The end of the pipeline 62 away from the ozone storage tank 61 is fixedly connected to the air inlet of the dispersion box 63. Inside the square shell 3, there are two long cavities 64. On the side of the inner wall of the long cavity 64 away from the HEPA filter element 4, a flow channel is provided. The flow channel is used for connecting the long cavity 64 and the air outlet of the dispersion box 63. On the side of the long cavity 64 close to the HEPA filter element 4, a plurality of round holes 65 are provided.

[0032] As Figure 2 shown, in this embodiment, the height of the second accommodation chamber 32 is greater than that of the first accommodation chamber 31. The number of round holes 65 opened on the right side of the second accommodation chamber 32 is increased to reduce the blockage of cold air.

[0033] As Figure 2 shown, in this embodiment, on the side of the HEPA filter element 4 close to the air outlet head 2, there are two symmetrical inclined surfaces. The contact area between the cold air and the HEPA filter element 4 is increased through the inclined surfaces, the cold air volume passing through in the same time is increased, and the blockage of cold air is reduced.

[0034] As Figure 2 shown, in this embodiment, a plurality of round holes 65 are all inclined, and the inclination angle of the round holes 65 is the same as that of the inclined surfaces on the HEPA filter element 4, so that the ozone blown out from the round holes 65 flows along the inclination direction of the inclined surfaces on the HEPA filter element 4, effectively reducing the sterilization dead angle.

[0035] As Figure 2 shown, in this embodiment, the two long cavities 64 are symmetrically arranged with the central horizontal plane passing through the square shell 3 as the symmetry plane. The two long cavities 64 are respectively located above and below the HEPA filter element 4. Ozone is blown out from the positions of the round holes 65 of the two long cavities 64 at the same time, and the sterilization treatment of bacteria at the two inclined surfaces on the left side of the HEPA filter element 4 is realized simultaneously.

[0036] As Figure 2As shown in the figure, in this embodiment, a guiding strip 66 is fixed to the side of the inner wall of the long cavity 64 close to the HEPA filter element 4. An inclined guiding surface is formed on the side surface of the guiding strip 66. After the ozone is guided by the guiding strip 66, it smoothly flows towards the position of the round hole 65, reducing the accumulation of ozone at the long cavity 64.

[0037] As Figure 2 shown in the figure, in this embodiment, a plurality of air outlet holes 5 are all inclined obliquely downward. The cold air blows downward obliquely, increasing the air fluidity at the position of the fruits and melons, and keeping the air at the position of the fruits and melons in a sterile state all the time.

[0038] As Figure 3 shown in the figure, in this embodiment, a plurality of air outlet holes 5 are distributed in a staggered manner. By means of the staggered distribution, more air outlet holes 5 can be opened, thereby increasing the air output of the square shell 3 and reducing the accumulation of cold air in the square shell 3.

[0039] Working principle: When the refrigeration device on the refrigerating chamber body 1 is started, cold air is blown out from the air outlet head 2. The cold air enters the first accommodating chamber 31 in the square shell 3. After the cold air passes through the HEPA filter element 4, the HEPA filter element 4 can effectively filter fine particles and bacteria in the air flow, effectively preventing bacteria from entering the refrigerating chamber body 1 to contact the stored fruits and melons, thereby prolonging the storage time of the fruits and melons and effectively preventing the fruits and melons from deteriorating and rotting. During the process of the HEPA filter element 4 filtering the cold air, the electromagnetic valve on the pipeline 62 is opened, so that the ozone in the ozone storage tank 61 enters the dispersion box 63 through the pipeline 62, and enters the long cavity 64 through the dispersion box 63 and the flow channel, and then is discharged from the position of the round hole 65 at the long cavity 64. The ozone blown out from the position of the round hole 65 contacts the bacteria on the HEPA filter element 4, realizing the sterilization treatment of the bacteria attached to the HEPA filter element 4, preventing the bacteria from growing and reproducing on the HEPA filter element 4, thereby ensuring the filtering ability of the HEPA filter element 4 for bacteria. After disinfecting for a period of time, just close the electromagnetic valve on the pipeline 62. The cold air is discharged from the position of the air outlet hole 5 after being filtered by the HEPA filter element 4, realizing the cooling inside the refrigerating chamber body 1.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without the description of these details.

[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
