Description

Technical Field

[0001] The utility model belongs to the technical field of fruit and vegetable fresh-keeping, and particularly relates to a fruit and vegetable modified atmosphere fresh-keeping device with self-generated gas. Background Art

[0002] For a current fruit and vegetable modified atmosphere fresh-keeping device with self-generated gas, it usually realizes the modified atmosphere by setting a silicone rubber window in the fresh-keeping box. The silicone rubber window can automatically adjust the gas components in the fresh-keeping box, so that the contents of oxygen and carbon dioxide are maintained within a relatively suitable range for fruit and vegetable storage. The suitable gas environment can effectively inhibit the respiration of fruits and vegetables, reduce the consumption of nutrients and the loss of moisture, and delay the ripening and aging process of fruits and vegetables, so as to achieve the purpose of fresh-keeping. However, the existing fresh-keeping devices also have some obvious disadvantages. First of all, the cooling components are arranged in the fresh-keeping box, which brings the problem of cumbersome and laborious disassembly and assembly. When the ice cubes melt and need to be replenished, the staff needs to operate inside the fresh-keeping box. Due to the limited internal space of the fresh-keeping box, the operation is very inconvenient, which increases the difficulty of replenishment, and may also cause unnecessary damage to other components during the disassembly and assembly process. The cumbersome disassembly and assembly method greatly affects the cleaning work inside the fresh-keeping box. During the long-term use of the fresh-keeping box, various dirt and bacteria will accumulate inside. However, due to the inconvenient disassembly and assembly of the cooling components, the cleaning work becomes more difficult, and the staff cannot achieve a comprehensive and thorough cleaning, thus providing a breeding ground for the growth of bacteria, reducing the reliability and hygiene standard of the fresh-keeping device. To solve this problem, we have developed a fruit and vegetable modified atmosphere fresh-keeping device with self-generated gas. Content of the Utility Model

[0024] A fixing hole 18 is opened below the rotating rod 17. The inner wall of the fixing hole 18 is provided with an internal thread. In the middle below the cover plate 8, there is a bottom rotating rod 16. The middle below the top rotating rod 14 is connected with the middle above the bottom rotating rod 16 through a rotating shaft 20. On the upper front and rear sides inside the fresh-keeping box 1, there is a fixing block 6 installed respectively. A clamping groove 7 is opened in the middle of the two fixing blocks 6 respectively.

[0025] A limiting plate 21 is installed on the outer side above the rotating shaft 20. The opening directions of the two clamping grooves 7 are opposite.

[0026] A handle 15 is installed above the top rotating rod 14. On the left and right sides above the cover plate 8, there is an ice inlet opened respectively.

[0027] The two ice inlets are respectively communicated with the interiors of the two ice storage boxes 9. Above the two ice inlets, there is a closing cover 11 provided respectively.

[0028] In the middle above the two closing covers 11, there is a lifting button 12 installed respectively. The positions of the two ice storage boxes 9 are symmetrical to the positions of the two cooling chambers 3 respectively.

[0029] The two drain valves 5 are respectively communicated with the interiors of the two cooling chambers 3. The lower end of the rotating rod 17 and the fixing hole 18 are rotationally connected through threads. An air supplement port 13 is opened on the right side above the cover plate 8. The external air supplement device can effectively adjust the internal gas components through the air supplement port 13, so as to realize active modified atmosphere packaging and enhance the applicability of the device.

[0030] Please refer to Figures 1 to 4, as the first embodiment of the present utility model: In actual use, place the fruits and vegetables to be preserved in the fresh-keeping box 1. Rotate the cross-shaped knob 19 counterclockwise to drive the rotating rod 17 to rotate out of the fixed hole 18. Then, pick up the cover plate 8 through the handle 15, rotate the top rotating rod 14 90° to the left. The top rotating rod 14 drives the bottom rotating rod 16 to rotate 90° through the rotating shaft 20. Then, align the two ice storage boxes 9 with the two cooling chambers 3 and insert them. Make the surface of the cover plate 8 contact with the upper surface of the fresh-keeping box 1. Then, rotate the top rotating rod 14 counterclockwise by 90° again, so that it drives the bottom rotating rod 16 to rotate through the rotating shaft 20. At the same time, the left end of the bottom rotating rod 16 rotates right rearward into the rear card slot 7, and its right end rotates left forward into the front card slot 7. After it enters, the position of the through hole corresponds to the position of the fixed hole 18. Then, drive the rotating rod 17 to rotate clockwise again through the cross-shaped knob 19, and screw its lower end into the fixed hole 18 to fix the top rotating rod 14, thereby realizing the sealing of the inside of the fresh-keeping box 1. After fixing, the fresh-keeping box 1 can be lifted through the handle 15. When disassembly is required, repeat the above steps in reverse to remove the cover plate 8, and then the two ice storage boxes 9 can be separated from the two cooling chambers 3, so as to facilitate the cleaning of the inside of the fresh-keeping box 1 and the inside of the cooling chamber 3 and prevent bacteria from breeding.

[0031] Please refer to Figure 1 and Figure 2 , as the second embodiment of the present utility model: Further elaborating on the first embodiment, after the cover plate 8 closes the fresh-keeping box 1, the closing cover 11 can be pulled upward through the lifting button 12 to open the ice inlet. Then, ice cubes can be added into the ice storage box 9 through the ice inlet. The ice cubes will cool the inside of the fresh-keeping box 1 through the cold air outlet 10 and the ventilation holes 4. Therefore, the fruits and vegetables can be effectively cooled. The water generated when the ice cubes melt can be discharged to the outside through the drain valve 5. And because there is a silicone rubber window 2 designed, the silicone rubber window 2 has special air permeability, and the permeability rates of oxygen and carbon dioxide are different. When the oxygen content in the fresh-keeping box 1 gradually decreases, due to the higher permeability rate of oxygen through the silicone rubber window 2 than that of carbon dioxide, the external oxygen will slowly enter the fresh-keeping box 1 through the silicone rubber window 2 under the action of the concentration difference to supplement the oxygen consumed by the fruits and vegetables. The carbon dioxide generated by the respiration of the fruits and vegetables will accumulate in the box. When the carbon dioxide concentration increases, the silicone rubber window 2 will allow the carbon dioxide to diffuse outward, thereby reducing the carbon dioxide concentration in the box. In this way, the silicone rubber window 2 can automatically adjust the gas components in the fresh-keeping box 1 to keep the contents of oxygen and carbon dioxide within a relatively suitable range for fruit and vegetable storage. The suitable gas environment can effectively inhibit the respiration of fruits and vegetables, reduce the consumption of nutrients and the loss of water, and delay the ripening and aging process of fruits and vegetables, so as to achieve the purpose of preservation.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
