The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model embodiment provides a refrigeration processing device for easy preservation of vegetables, such as... Figure 1-3As shown, the refrigeration processing device for facilitating vegetable preservation includes: a refrigerator box 1; a partition 2, which is fixedly installed inside the refrigerator box 1 and divides the refrigerator box 1 into a refrigeration chamber 3 and an installation chamber 4; a refrigeration pipe 5, which is fixedly installed inside the partition 2 and is correspondingly arranged with the refrigeration chamber 3; a carbon dioxide cylinder 6, which is disposed inside the installation chamber 4; an exhaust pipe 7, which is fixedly installed on the top of the carbon dioxide cylinder 6; a solenoid valve 8, which is disposed on the exhaust pipe 7; and an exhaust mechanism, which is disposed inside the installation chamber 4 for introducing carbon dioxide into the refrigeration chamber 3.

[0020] In this embodiment, the refrigerator 1 serves as the main body of the entire preservation device, providing a closed environment to maintain the low-temperature conditions required for vegetable storage. The refrigerator's design ensures stable internal temperature, which is fundamental to vegetable preservation. A partition 2 cleverly divides the internal space of the refrigerator 1 into a refrigeration chamber 3 and an installation chamber 4. This division not only optimizes space utilization but also allows the refrigeration system and carbon dioxide supply system to be installed independently without interference, improving the overall efficiency and reliability of the device. Refrigeration pipes 5 are fixedly installed within the partition 2 and directly correspond to the refrigeration chamber 3. By circulating refrigerant, the refrigeration pipes 5 effectively lower the temperature within the refrigeration chamber, providing a suitable low-temperature environment for the vegetables, slowing their metabolism, and thus extending their shelf life. A carbon dioxide cylinder 6, a key component of modified atmosphere storage, is installed within the installation chamber 4 and stores liquid or high-pressure gaseous carbon dioxide. Carbon dioxide is an effective preservative gas that inhibits vegetable respiration, reducing nutrient loss and microbial growth. An exhaust pipe 7 connects the carbon dioxide cylinder 6 to the refrigeration chamber 3, ensuring that carbon dioxide can be smoothly delivered into the refrigeration chamber. Its design takes into account both smooth gas flow and airtightness, preventing gas leakage. A solenoid valve 8, installed on the exhaust pipe 7, is used to precisely control the amount and timing of carbon dioxide release. By adjusting the opening and closing of the solenoid valve, the carbon dioxide concentration within the refrigeration chamber can be precisely controlled to achieve optimal preservation. The exhaust mechanism is responsible for extracting carbon dioxide from the carbon dioxide cylinder 6 and delivering it to the refrigeration chamber 3 through the exhaust pipe 7 and the solenoid valve 8. By combining refrigeration and modified atmosphere packaging (MAP) technology, the respiration and microbial growth of vegetables are effectively inhibited, reducing nutrient loss and spoilage, and significantly improving the preservation effect of vegetables.

[0021] In a further preferred embodiment of the present invention, the exhaust mechanism includes a connecting pipe 9, an air pump 10, and an exhaust pipe 11. The connecting pipe 9 is fixedly installed on the exhaust pipe 7, the air pump 10 is fixedly installed in the mounting cavity 4, the input end of the air pump 10 is fixedly connected to the connecting pipe 9, the exhaust pipe 11 is fixedly installed on the output end of the air pump 10, and the other end of the exhaust pipe 11 extends into the refrigeration cavity 3.

[0022] In this embodiment, the connecting pipe 9, acting as a bridge between the air pump 10 and the exhaust pipe 7, is fixedly installed on the exhaust pipe 7. It ensures that the carbon dioxide released from the carbon dioxide cylinder 6 can smoothly enter the air pump 10, providing the necessary channel for subsequent gas delivery. The air pump 10, as the core component of the exhaust mechanism, is fixedly installed inside the mounting cavity 4. The input end of the air pump 10 is fixedly connected to the connecting pipe 9, responsible for drawing in carbon dioxide from the carbon dioxide cylinder 6 and increasing the gas pressure or flow rate through its internal mechanical structure, enabling it to be delivered more effectively into the refrigerator cavity 3. The exhaust pipe 11 is fixedly installed at the output end of the air pump 10, serving as the final channel for carbon dioxide to enter the refrigerator cavity 3 from the air pump 10. The other end of the exhaust pipe 11 extends into the refrigerator cavity 3, ensuring that the carbon dioxide can be evenly and stably distributed throughout the refrigerator cavity, thereby achieving optimal preservation. By introducing the air pump 10, this embodiment significantly enhances the gas delivery capacity of the exhaust mechanism. The air pump can generate sufficient pressure or flow rate to ensure that carbon dioxide can quickly and evenly fill the refrigerator cavity, improving preservation efficiency. In conjunction with the solenoid valve 8, the air pump 10 can precisely control the carbon dioxide concentration within the refrigerator compartment. By adjusting the air pump's operating time and the opening and closing degree of the solenoid valve, the amount of carbon dioxide released can be precisely adjusted to achieve optimal preservation. Because carbon dioxide can be more effectively delivered to every corner of the refrigerator compartment, and its concentration is precisely controlled, the preservation effect of vegetables is further improved. Respiration is more effectively suppressed, and nutrient loss and microbial growth are correspondingly reduced.

[0023] In a further preferred embodiment of this utility model, the refrigerator box 1 is provided with a humidification mechanism for replenishing moisture to vegetables. The humidification mechanism includes a water pump 12, a drain pipe 13, a nozzle 14, a water inlet pipe 15, and an adapter 16. The water pump 12 is fixedly installed on the refrigerator box 1, the drain pipe 13 is fixedly installed on the output end of the water pump 12, and the drain pipe 13 extends into the refrigerator cavity 3. There are multiple nozzles 14, and all of the multiple nozzles 14 are fixedly installed on the drain pipe 13. The water inlet pipe 15 is fixedly installed on the input end of the water pump 12, and the adapter 16 is fixedly installed on the water inlet pipe 15.

[0024] In this embodiment, the water pump 12 serves as the power source for the humidification mechanism and is fixedly installed on the refrigerator compartment 1. The water pump generates pressure to draw water from an external water source and delivers it to the refrigerator compartment 3 through the drain pipe 13. The drain pipe 13 is responsible for delivering the water output from the pump to various locations within the refrigerator compartment to ensure uniform humidification of the vegetables. The nozzle 14 sprays the water from the drain pipe in a mist form, which increases the humidity within the refrigerator compartment while preventing water accumulation on the vegetable surface caused by direct watering. The water inlet pipe 15 ensures a continuous and stable water supply for the water pump, meeting the operational requirements of the humidification mechanism. The adapter 16 connects to external water sources of different specifications or types. The adapter makes the humidification mechanism more flexible and versatile, adapting to different usage conditions. The humidification mechanism replenishes the vegetables with moisture in a timely manner, preventing them from losing freshness and flavor due to water loss during refrigeration. This is crucial for maintaining the quality and nutritional value of vegetables. Appropriate humidity helps inhibit respiration and microbial growth in vegetables, thereby extending their shelf life. The humidification mechanism provides a more suitable storage environment for vegetables by regulating the humidity inside the refrigerator compartment. The design of the humidification mechanism makes using the refrigeration processing unit more convenient and worry-free for users. There is no need to manually water the vegetables, reducing the user's workload and time costs.

[0025] In a further preferred embodiment of the present invention, a support plate 17 is fixedly installed in the refrigeration chamber 3, and the support plate 17 has holes, and there are multiple holes.

[0026] In this embodiment, the support plate 17 is fixedly installed inside the refrigerator cavity 3 to support fresh items such as vegetables. The design of the support plate allows vegetables to be neatly arranged in the refrigerator cavity, avoiding the problems of water accumulation and difficulty in cleaning that may occur from direct contact with the bottom of the refrigerator. Multiple holes are formed in the support plate 17. These holes serve several functions. First, they increase the permeability of the support plate, facilitating air circulation within the refrigerator cavity and reducing the impact of humidity buildup and condensation dripping on the vegetables. Second, the holes also act as drainage channels, promptly draining excess moisture from the surface of the vegetables and keeping them dry. The design of the support plate and its holes helps maintain air circulation and humidity balance within the refrigerator cavity, providing a more suitable preservation environment for the vegetables. This helps reduce rotting and spoilage, extending their shelf life. The design of the support plate makes the arrangement of vegetables more orderly, reducing clutter within the refrigerator cavity. Simultaneously, the holes, acting as drainage channels, reduce water accumulation, lowering the difficulty and frequency of cleaning and maintenance.

[0027] In a further preferred embodiment of the present invention, two fixing brackets 18 are fixedly installed at the bottom of the support plate 17, and a fan 19 is fixedly installed on each of the two fixing brackets 18.

[0028] In this embodiment, the mounting bracket 18 is fixedly installed at the bottom of the support plate 17, serving as a structure to support and fix the fan 19. The design of the mounting bracket ensures that the fan can operate stably without affecting the placement and preservation effect of vegetables on the support plate. The fan 19 is installed on two mounting brackets 18 respectively to promote air circulation within the refrigerator cavity 3. The fan generates airflow by rotating, circulating and exchanging the air within the refrigerator cavity, which helps reduce problems such as temperature gradients, humidity accumulation, and odors. The addition of the fan 19 significantly enhances the air circulation effect within the refrigerator cavity 3. Enhanced air circulation also helps reduce odor accumulation within the refrigerator cavity. Vegetables may produce some odors during the preservation process. If the air does not circulate, these odors will gradually accumulate and affect the preservation effect of other vegetables. The circulation action of the fan can promptly expel odors from the refrigerator cavity, keeping the air fresh. Enhanced air circulation not only helps reduce problems such as temperature gradients and humidity accumulation but also improves the preservation efficiency within the refrigerator cavity. By continuously circulating and exchanging air, the moisture on the surface of vegetables can evaporate more easily, reducing rotting caused by water accumulation. At the same time, air circulation also helps inhibit the reproduction and growth of microorganisms, further extending the shelf life of vegetables.

[0029] In a further preferred embodiment of the present invention, a collection box 20 is slidably disposed at the bottom of the refrigeration chamber 3, and the collection box 20 is disposed under the two fixing frames 18.

[0030] In this embodiment, the collection box 20 is slidably disposed at the bottom of the refrigerator cavity 3, mainly used to collect water, drips, or impurities that may be generated from the holes in the support plate 17 and during the operation of the fan 19. The design of the collection box allows users to easily remove and clean it, maintaining the cleanliness and hygiene of the refrigerator cavity. The collection box 20 effectively collects and stores water, drips, or impurities at the bottom of the refrigerator cavity, preventing the accumulation and spread of these substances within the refrigerator cavity. This helps reduce odors and bacterial growth in the refrigerator cavity, thus maintaining a cleaner and more hygienic preservation environment. The sliding design of the collection box 20 allows users to easily remove it from the refrigerator cavity for cleaning. This design not only simplifies the maintenance process but also improves maintenance efficiency, making it easier for users to keep the refrigerator cavity clean and tidy. Placing the collection box 20 below the two mounting brackets 18 avoids occupying valuable preservation space on the support plate 17 while fully utilizing the space at the bottom of the refrigerator cavity. This design allows for a more rational use and allocation of space within the refrigerator cavity.

[0031] In a further preferred embodiment of this utility model, two sealing doors 21 are hinged to the refrigerator box 1. The two sealing doors 21 are respectively arranged corresponding to the refrigerator cavity 3 and the mounting cavity 4. An environmental detector 22 is fixedly installed in the refrigerator cavity 3. An operation controller 23 is fixedly installed on any of the sealing doors 21. A display screen is provided on the operation controller 23.

[0032] In this embodiment, the sealing door 21 allows users to easily open or close the refrigeration chamber and installation chamber for storing and retrieving vegetables or performing equipment maintenance. Simultaneously, the sealing door also provides insulation, helping to reduce energy loss within the refrigeration chamber. The environmental monitoring instrument 22 is used to monitor environmental parameters such as temperature, humidity, and gas concentration within the refrigeration chamber in real time. The introduction of the environmental monitoring instrument 22 allows users to accurately understand the environmental conditions within the refrigeration chamber, enabling them to make appropriate adjustments and optimizations as needed. The operation controller 23 is the main interface for user interaction with the refrigeration processing device. Users can use it to view environmental parameters within the refrigeration chamber, set preservation parameters, and control the equipment's operation. The addition of a display screen makes the operation process more intuitive and convenient. The introduction of the environmental monitoring instrument enables the refrigeration processing device to monitor and automatically adjust environmental parameters in real time. Users can set preservation parameters as needed, and the equipment will automatically adjust environmental parameters such as temperature, humidity, and gas concentration within the refrigeration chamber based on these parameters to achieve optimal preservation results. This intelligent design not only improves preservation efficiency but also reduces the difficulty and labor intensity for users.

[0033] In summary, compared with related technologies, by precisely controlling environmental parameters such as temperature, humidity, and carbon dioxide concentration within the refrigeration chamber, the respiration and microbial growth of vegetables are effectively inhibited, significantly extending their shelf life and maintaining their freshness and taste. The introduction of an environmental monitoring instrument and operating controller enables real-time monitoring and intelligent adjustment of the refrigeration chamber environment. Users can set preservation parameters as needed, and the equipment automatically adjusts to the optimal preservation state, reducing operational difficulty and labor intensity. A collection box is designed to collect accumulated water, drips, and other impurities at the bottom of the refrigeration chamber, allowing users to easily remove and clean it, maintaining cleanliness and hygiene within the refrigeration chamber. Simultaneously, the perforations on the support plate and the fan design also help reduce water accumulation, lowering cleaning difficulty. The rational layout of the support plate, its fixing frame, and the fan ensures neat arrangement of vegetables while fully utilizing the space within the refrigeration chamber.

In addition to basic refrigeration and preservation functions, this device also has multiple functions such as humidification, ventilation, and environmental monitoring, comprehensively meeting the preservation needs of vegetables and other foods. Through intelligent and user-friendly design, such as the display screen of the control controller and the heat preservation effect of the door, the user experience and satisfaction have been improved.
