Description

Technical Field

[0001] The utility model belongs to the technical field of electric field fresh-keeping and refrigeration, and in particular relates to a cold storage with an electric field fresh-keeping function. Background Art

[0002] In the field of agricultural product storage and preservation, the use of cold storage technology has become a key means of ensuring the quality of fruits, vegetables, and other agricultural products and extending their shelf life. Traditional storage methods often fail to effectively control the temperature and humidity of the storage environment, making fruits and vegetables susceptible to temperature fluctuations during storage and transportation. This accelerates their aging and decay, resulting in significant quality degradation and increased waste.

[0003] In the prior art, a Chinese patent document such as announcement number CN213273356U provides an energy-saving fruit preservation cold storage, comprising a cold storage body, two connecting pipes running through the bottom of the cold storage body, an exchange pipe fixed between the two connecting pipes and located at the bottom of the cold storage body, an evaporation pipe fixed between the two connecting pipes and located inside the cold storage body, and a compressor provided on the evaporation pipe. In addition, fans are provided on both sides of the inner wall of the cold storage body and corresponding to the metal mesh. This fruit preservation cold storage provides a certain solution for the storage and preservation of agricultural products. However, traditional low-temperature cold storage only serves to lower the ambient temperature for the purpose of storing food. Long-term operation of the cold storage will accelerate the dehydration and wilting of stored goods such as agricultural products, making their surface hard. Existing low-temperature cold storage cannot maintain the fresh quality of stored goods such as agricultural products while extending the shelf life.

[0004] Therefore, in order to solve the problems existing in the prior art, it is urgent to provide a cold storage with an electric field preservation function. Summary of the Invention

[0005] In response to the problems in the related technology, the utility model proposes a cold storage with an electric field preservation function to overcome the technical problem that the existing low-temperature refrigeration technology is difficult to maintain the fresh quality of stored products such as agricultural products.

[0006] The technical solution of the utility model is achieved as follows: a cold storage with an electric field preservation function, comprising a cold storage body, wherein the cold storage body is provided with a refrigeration unit for refrigeration, a humidification device, a gas composition control device and an electric field emission device; the humidification device is used to increase the humidity inside the cold storage body; the gas composition control device is used to discharge air from the cold storage body or introduce air from outside the cold storage body;

[0007] The electric field generating device includes an electric field generator and an electric field network module; the electric field network module includes a fixed guardrail grid component and a sliding curtain grid component, which are alternately arranged inside the cold storage body; each grid component is provided with a metal conductor and is connected to the electric field generator through its own metal conductor;

[0008] The fixed guardrail power grid assembly includes a guardrail body, which is fixed to the ground and insulated from the ground by rubber parts; the sliding curtain power grid assembly includes a hanger suspended on the top of the cold storage body, and the hanger is provided with a guide rail extending in the horizontal direction. The guide rail is slidably connected to the curtain body, and the curtain body is manually or automatically retracted or unfolded along the guide rail.

[0009] The utility model arranges an electric field emission device in the cold storage body. On the basis of retaining the inlet and outlet channels without affecting the transportation of goods, an electrostatic field is applied around the refrigerated goods through the alternate arrangement of fixed guardrail grid components and sliding curtain grid components, so that the water molecules in the food are resonantly activated. At the same time, the electrostatic field can be used to inhibit the reproduction of bacteria to varying degrees, thereby achieving the purpose of extending the shelf life of refrigerated goods.

[0010] As a further improvement to the above solution, the cold storage body is provided with at least one channel, with the fixed guardrail grid assembly and the sliding curtain grid assembly distributed on both sides of the channel; the fixed guardrail grid assembly and the sliding curtain grid assembly are arranged in parallel, with a storage space between the two adjacent components for placing refrigerated goods. The fixed guardrail grid assembly provides a stable storage boundary, while the sliding curtain grid assembly offers flexibility and can be opened or closed as needed to adjust the size of the storage space. This design allows for flexible adjustment of storage space based on the type, quantity, and size of the refrigerated goods, maximizing space utilization.

[0011] As a further improvement to the above solution, when refrigerated goods enter / exit the cold storage body, the curtain body is retracted toward one end of the guide rail; when the refrigerated goods are placed in the accommodation space, the curtain body is unfolded along the guide rail to form the accommodation space with the adjacent fixed guardrail power grid assembly. When refrigerated goods need to enter / exit the cold storage body, the curtain body is retracted toward one end of the guide rail to form a spacious opening, which is convenient for forklifts, trolleys and other handling tools to pass through quickly without detouring or waiting, greatly improving the efficiency of entering and exiting the warehouse. At the same time, when the refrigerated goods are located in the accommodation space, the curtain body is unfolded and enclosed around the refrigerated goods, using the electrostatic field to inhibit bacterial reproduction, thereby improving the refrigeration and preservation effect.

[0012] As a further improvement to the above solution, the guardrail body includes a support frame; the bottom of the support frame is provided with a plurality of legs, each of which is pressed against and fixed to the ground by the rubber member; the metal conductor is provided on the upper portion of the support frame. The rubber member is used to insulate the metal conductor from the ground, thereby preventing static electricity from being conducted away and ensuring that the static field is stably applied to the surrounding area of ​​the refrigerated goods, thereby ensuring the preservation effect.

[0013] As a further improvement to the above solution, the guide rails slide in conjunction with rollers, which are equipped with hooks for securing the curtain body. The metal conductor, in the form of a flexible wire, is provided on the surface of the curtain body. This sliding engagement between the guide rails and rollers allows for smooth movement of the curtain body during deployment and retraction, reducing friction and resistance and ensuring efficient transport of refrigerated goods in and out of the warehouse.

[0014] As a further improvement to the above solution, the curtain body is made of a low-temperature-resistant and mildew-resistant flexible fabric. Cold storage environments are typically extremely cold, and ordinary fabrics tend to harden, become brittle, and even crack in such conditions. However, low-temperature-resistant fabrics remain soft and resilient in low-temperature conditions, making them less susceptible to damage and thus extending the service life of the curtain body.

[0015] As a further improvement of the above solution, the metal conductor is composed of multiple battery cores, each battery core is connected to a cable and connected to the electric field generator through the cable; or, the metal conductor is woven into a mesh along the surface of the power grid component and connected to the electric field generator through a cable; or, the metal conductor extends in a folded manner along the surface of the power grid component and is connected to the electric field generator through a cable.

[0016] As a further improvement to the above solution, the humidification device includes a water tank, an atomizer, and an air supply pipe connected in sequence; the air supply pipe is arranged along the wall or ceiling of the cold storage body, and a nozzle is installed at the end of the air supply pipe or at an appropriate position; the atomizer atomizes water molecules in the water tank into a mist, which is transported through the air supply pipe and sprayed into the cold storage body through the nozzle. In addition to existing low-temperature refrigeration cold storage, the installation of a humidification device can reduce the dryness of refrigerated goods caused by long-term operation of the refrigeration unit.

[0017] As a further improvement to the above solution, the air supply duct is installed on one wall of the cold storage body, and the refrigeration unit is installed on the opposite wall. If condensed water produced by the refrigeration unit comes into contact with the air supply duct, it may affect the humidity of the supply air. Placing the refrigeration unit and air supply duct on opposite walls can effectively reduce the chance of such contact, thereby reducing the negative impact of condensed water on the humidity of the supply air.

[0018] As a further improvement of the above scheme, the gas composition control device includes a gas composition concentration sensing probe, a detection device and a fresh air ventilation device; the gas composition concentration sensing probe is connected to the detection device via a cable or a wireless signal module, and the detection device is connected to the fresh air ventilation device via a cable; the gas composition concentration sensing probe is used to monitor the gas composition in the cold storage body and send it to the detection device; the detection device controls the start and stop of the fresh air ventilation device to exhaust the air in the storage or introduce air from outside the storage. The gas composition control device can sense the gas composition inside the cold storage through the sensing probe, exhaust the air in the storage, and introduce fresh air through the fresh air ventilation device, which can effectively reduce the ripening effect of the gas in the storage on the refrigerated food and delay the shelf life of the refrigerated food.

[0019] Beneficial effects of the utility model:

[0020] (1) The utility model arranges an electric field emission device in the cold storage body. On the basis of retaining the inlet and outlet channels without affecting the transportation of goods, the utility model applies an electrostatic field around the refrigerated goods through the alternate arrangement of fixed guardrail grid components and sliding curtain grid components, so that the water molecules in the food are resonantly activated. At the same time, the electrostatic field can be used to inhibit the reproduction of bacteria to varying degrees, thereby achieving the purpose of extending the shelf life of the refrigerated goods.

[0021] (2) On the basis of the existing low-temperature refrigeration in cold storage, the installation of a humidification device can reduce the dryness loss of refrigerated products caused by the long-term operation of the refrigeration device; the gas composition control device can remove the air in the warehouse and introduce fresh air, which can effectively reduce the ripening effect of the gas in the warehouse on the refrigerated food and delay the shelf life of the refrigerated products.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example

[0038] like Figure 1-Figure 5 As shown, a cold storage with electric field preservation function includes a cold storage body 1, in which a refrigeration unit 2 for refrigeration, a humidifying device 3, a gas composition control device 4 and an electric field emission device 5 are arranged.

[0039] The humidifying device 3 is used to increase the humidity inside the cold storage body 1. In this embodiment, the humidifying device 3 includes a water tank (not shown), an atomizer (not shown), and an air supply pipe 31 connected in sequence. The air supply pipe 31 is arranged along the wall or ceiling of the cold storage body 1. Nozzles (not shown) are installed at the end of the air supply pipe 31 or at appropriate positions. The appropriate positions refer to the nozzles distributed at intervals along the extension direction of the air supply pipe 31. The atomizer atomizes the water molecules in the water tank into water mist, which is transported through the air supply pipe 31 and sprayed into the cold storage body 1 through the nozzle.

[0040] On the basis of the existing cold storage low temperature refrigeration, by providing a humidification device 3, the dry loss of refrigerated goods caused by the long-term operation of the refrigeration device can be reduced. In this embodiment, the air supply pipe 31 is arranged on the wall of one side of the cold storage body 1, and the refrigeration unit 2 is arranged on the other opposite wall. If the condensed water produced by the refrigeration unit 2 comes into contact with the air supply pipe 31, it may affect the humidity of the supply air. By arranging the refrigeration unit 2 and the air supply pipe 31 on two opposite walls, the chance of such contact can be effectively reduced, thereby reducing the negative impact of condensed water on the humidity of the supply air.

[0041] The gas composition control device 4 is used to discharge the air in the cold storage body 1 or introduce the air outside the cold storage body 1; in this embodiment, the gas composition control device 4 includes a gas composition concentration sensing probe, a detection device (not shown in the figure) and a fresh air ventilation device 41; the gas composition concentration sensing probe is connected to the detection device through a cable or a wireless signal module, and the detection device is connected to the fresh air ventilation device 41 through a cable.

[0042] The gas component concentration sensing probe is used to monitor the gas components (such as carbon dioxide, ethylene and oxygen, etc.) in the cold storage body 1 and send it to the detection device; the detection device controls the start and stop of the fresh air ventilation device 41 according to whether the gas components in the storage exceed the preset threshold. The fresh air ventilation device 41 is provided with at least a valve connected to the outside world, and the air in the storage is discharged or the air outside the storage is introduced by opening and closing the valve. The gas composition control device 4 can sense the gas components inside the cold storage through the sensing probe, discharge the air in the storage, and introduce fresh air by opening the fresh air ventilation device 41, which can effectively reduce the ripening effect of the gas in the storage on the refrigerated food and delay the shelf life of the refrigerated food.

[0043] The electric field generating device includes an electric field generator (not shown in the figure) and an electric field network module; the electric field network module includes a fixed guardrail grid component 51 and a sliding curtain grid component 52, which are alternately arranged inside the cold storage body 1; each grid component is provided with a metal conductor J1, and is connected to the electric field generator through its own metal conductor J1; in this embodiment, the metal conductor J1 is composed of a plurality of battery cores, each battery core is connected to a cable, and is connected to the electric field generator through the cable; or, the metal conductor J1 is woven into a net along the surface of the grid component and is connected to the electric field generator through a cable; or, the metal conductor J1 extends in a folded manner along the surface of the grid component and is connected to the electric field generator through a cable.

[0044] The fixed guardrail power grid assembly 51 includes a guardrail body 511, which is fixed to the ground and insulated from the ground by a rubber member 512. Specifically, the guardrail body 511 includes a support frame 5111. The bottom of the support frame 5111 is provided with a plurality of legs 5112, each of which is pressed against and fixed to the ground by a rubber member 512. The metal conductor J1 is installed on the upper portion of the support frame 5111. The rubber member 512 is used to insulate the ground and prevent static electricity from being conducted away, ensuring a stable static field around the refrigerated goods and maintaining freshness.

[0045] The sliding curtain power grid assembly 52 includes a suspension rod 521 suspended from the top of the cold storage body 1. The suspension rod 521 is provided with a horizontally extending guide rail 522. A curtain body 523 is slidably connected to the guide rail 522. The curtain body 523 can be manually or automatically retracted or extended along the guide rail 522. In this embodiment, the curtain body 523 can be manually retracted or extended. The guide rail 522 slides with a roller 524, which is provided with a hook 525 for securing the curtain body 523. The surface of the curtain body 523 is provided with the metal conductor J1, which is in the form of a soft wire. The sliding fit between the guide rail 522 and the roller 524 allows the curtain body 523 to move smoothly during the expansion and contraction process, reducing friction and resistance and ensuring efficient transportation of refrigerated goods in and out of the warehouse. In other embodiments, the curtain can also be retracted or extended in a manner similar to that of an electric curtain.

[0046] In this embodiment, the curtain body 523 is made of low-temperature resistant and mildew-proof flexible fabric. The temperature in a cold storage environment is usually extremely low, and ordinary fabrics tend to harden, become brittle, or even crack in such an environment. However, low-temperature resistant fabrics can remain soft and tough under low-temperature conditions and are not easily damaged, thereby extending the service life of the curtain body 523. The low-temperature resistant and mildew-proof flexible fabrics that can be used include polyvinyl chloride (PVC) coated fabrics or silicone coated fabrics. These fabrics not only have the characteristics of low-temperature resistance and mildew resistance, but also have good waterproof and moisture-proof properties, and can maintain stable performance in special environments such as cold storage.

[0047] In this embodiment, the cold storage body 1 is provided with at least one channel 11, with the fixed guardrail grid assembly 51 and the sliding curtain grid assembly 52 distributed on both sides of the channel 11; the fixed guardrail grid assembly 51 and the sliding curtain grid assembly 52 are arranged in parallel, with a storage space 12 between the two adjacent components for placing refrigerated goods. The fixed guardrail grid assembly 51 provides a stable storage boundary, while the sliding curtain grid assembly 52 is flexible and can be opened or closed as needed to adjust the size of the storage space 12. This design allows for flexible adjustment of the storage space according to the type, quantity, and size of the refrigerated goods, thereby maximizing the use of space.

[0048] Through the above-mentioned scheme of the present invention, in a specific application: a cold storage with an electric field preservation function, an electric field emission device 5 is arranged in the cold storage body 1, and on the basis of retaining the inlet and outlet channels 11 without affecting the transportation of goods, an electrostatic field is applied around the refrigerated goods through the alternating arrangement of fixed guardrail grid components 51 and sliding curtain grid components 52, so that the water molecules in the food are resonantly activated, and at the same time, the electrostatic field can inhibit the reproduction of bacteria to varying degrees, thereby achieving the purpose of extending the shelf life of the refrigerated goods. Specifically, when the refrigerated goods enter / exit the cold storage body 1, the curtain body 523 is retracted toward one end of the guide rail 522; when the refrigerated goods are placed in the accommodating space 12, the curtain body 523 is unfolded along the guide rail 522, forming the accommodating space 12 with the adjacent fixed guardrail grid components 51. When refrigerated goods need to enter or exit the cold storage body 1, the curtain body 523 retracts toward one end of the guide rail 522, forming a wide opening. This allows for forklifts, carts, and other transport tools to quickly pass through without having to detour or wait, significantly improving entry and exit efficiency. Furthermore, once the refrigerated goods are positioned in the storage space 12, the curtain body 523 unfolds and surrounds the goods, utilizing the electrostatic field to inhibit bacterial growth and enhance refrigeration and preservation.
