Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically to an air-circulating cold storage. Background Technology

[0002] In the field of agricultural product storage, the preservation of fruits and vegetables is of paramount importance, directly affecting their quality and sales cycle. Small cold storage facilities, as a common type of storage equipment, can provide a relatively stable low-temperature environment for fruits and vegetables, extending their shelf life.

[0003] Traditional small cold storage facilities often lack an effective air circulation system, resulting in uneven distribution of cold air inside the storage room. This can easily lead to localized high or low temperature dead zones, affecting the preservation of fruits and vegetables. Furthermore, traditional cold storage facilities often use solid pallets, which can obstruct the normal flow of cold air and further affect the uniformity of temperature inside the storage room. Therefore, an air circulation cold storage system is proposed to improve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an air-circulating cold storage. By setting up circulation components and trays, it solves the problem that traditional small cold storages usually lack an effective air circulation system, resulting in uneven distribution of cold air inside the storage, which can easily lead to local high or low temperature dead zones, affecting the preservation effect of fruits and vegetables. In addition, traditional cold storages mostly use solid trays, which can block the normal flow of cold air and further affect the uniformity of temperature inside the storage.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is an air-circulating cold storage, including a cold storage body, a circulation component, and a tray. The circulation component is installed on the cold storage body and includes a circulating fan, a refrigerator, and an air duct plate. The air inlet end of the circulating fan is connected to an air inlet hood, and the air outlet end of the circulating fan is connected to a first pipe. The air inlet end of the refrigerator is connected to the first pipe, and the air outlet end of the refrigerator is connected to a second pipe. The second pipe is connected to the inner cavity of the air duct plate, and the bottom of the air duct plate is connected to multiple air outlet hoods. The tray is installed on the cold storage body and has multiple ventilation holes.

[0007] Furthermore, the circulation assembly also includes a third pipe, an air inlet hood connected to the third pipe, the third pipe being installed on the inner wall of the cold storage body by a snap fastener, a fourth pipe connected to the third pipe, the fourth pipe being connected to the cold storage body, and the end of the fourth pipe away from the third pipe being connected to the air inlet of the circulation fan.

[0008] Furthermore, a support plate is installed on the air duct plate, and the end of the support plate away from the air duct plate is installed on the top of the inner cavity of the cold storage body. The circulating fan and the refrigeration unit are both installed on the cold storage body. The fourth pipe, the first pipe and the second pipe are all installed on the cold storage body by clips.

[0009] Furthermore, corresponding limiting grooves are provided on both sides of the cold storage body, and the two ends of the pallet respectively cooperate with the two limiting grooves, and multiple pallets are provided.

[0010] Furthermore, the cold storage unit has a hinged door at its opening, a door lock is installed on the door, and casters are installed at the bottom of the cold storage unit and at its four corners.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model, by setting up a circulation component, allows air inside the cold storage body to enter the air intake end of the circulation fan through the air inlet hood, the third pipe and the fourth pipe, and then be transported to the air intake end of the refrigeration unit through the first pipe. After the refrigeration unit cools the air, it is then evenly diffused into the cold storage body through the second pipe, the air duct plate and the air outlet hood, thus achieving cold air circulation. This solves the problem that traditional small cold storages usually lack an effective air circulation system, resulting in uneven distribution of cold air inside the storage, which can easily lead to local high temperature or low temperature dead zones, affecting the preservation effect of fruits and vegetables.

[0013] 2. This utility model sets up multiple trays with multiple ventilation holes on the trays, allowing the air inside the cold storage body 1 to flow vertically. This solves the problem that traditional cold storages mostly use solid trays, which would block the normal flow of cold air and further affect the uniformity of the temperature inside the storage.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an air-circulating cold storage, including a cold storage body 1, which is a small cold storage for storing fruits and vegetables, thereby extending the shelf life of fruits and vegetables.

[0023] The circulation assembly 2 is installed on the cold storage body 1. There are two sets of circulation assemblies 2. Each circulation assembly 2 includes a circulating fan 201, a refrigerator 204, an air duct plate 206, and a third pipe 208. The air inlet end of the circulating fan 201 is connected to an air inlet hood 202, and the air outlet end flange of the circulating fan 201 is connected to a first pipe 203. The air inlet end of the refrigerator 204 is connected to the flange of the first pipe 203, and the air outlet end flange of the refrigerator 204 is connected to a second pipe 205. The second pipe 205 is connected to the cold storage body 1. The top of the body 1 is connected, the second pipe 205 is connected to the inner cavity of the air duct plate 206, the bottom of the air duct plate 206 is connected to multiple air outlet hoods 207, the air inlet hood 202 is flanged and connected to the third pipe 208, the third pipe 208 is installed on the inner wall of the cold storage body 1 by a snap fastener, the flange on the third pipe 208 is connected to the fourth pipe 209, the fourth pipe 209 is connected to the cold storage body 1, and the end of the fourth pipe 209 away from the third pipe 208 is connected to the air inlet flange of the circulating fan 201.

[0024] When it is necessary to circulate the cold air inside the cold storage body 1, the circulating fan 201 and the refrigerator 204 are first started by the external controller. The air inside the cold storage body 1 enters the third pipe 208 through the air inlet hood 202, and then is drawn into the air inlet of the circulating fan 201 through the fourth pipe. The air outlet of the circulating fan 201 delivers the drawn-in cold air to the air inlet of the refrigerator 204 through the first pipe 203. The refrigerator 204 cools the air. The cooled air enters the second pipe 205 from the air outlet of the refrigerator 204 and then enters the inner cavity of the air duct plate 206. Finally, it is evenly diffused into the cold storage body 1 by the air outlet hood 207, thereby cooling and preserving the fruits and vegetables in the cold storage body 1. Repeating the above air circulation process can make the cold air distribution in the cold storage body 1 more uniform.

[0025] A support plate 210 is bolted onto the air duct plate 206. The end of the support plate 210 away from the air duct plate 206 is bolted onto the top of the inner cavity of the cold storage body 1. The circulating fan 201 and the refrigerator 204 are both bolted onto the outer wall of the cold storage body 1. The fourth pipe 209, the first pipe 203 and the second pipe 205 are all fastened onto the cold storage body 1.

[0026] The tray 3 is set on the cold storage body 1. Multiple trays 3 can be set according to actual needs. Multiple ventilation holes 301 are evenly opened on the tray 3. Corresponding limiting grooves 101 are opened on both sides of the cold storage body 1. The two ends of the tray 3 are respectively slidably engaged with the two limiting grooves 101.

[0027] When it is necessary to place the tray 3 on the limiting groove 101, insert the two sides of the tray 3 into the two limiting grooves 101, and then push the tray 3 inward so that the tray 3 can be stably placed on the limiting groove 101, which is convenient for loading and unloading fruits and vegetables. Multiple trays 3 can be placed in layers to make full use of the internal space of the cold storage body 1. The ventilation holes 301 on the tray 3 can allow cold air to flow freely up and down, avoiding the problem of local high temperature or low temperature dead corners caused by the airflow being blocked by traditional solid trays.

[0028] The cold storage body 1 is hinged to a door 4 at its opening, and a door lock is installed on the door 4. Casters 5 are bolted to the bottom of the cold storage body 1 at its four corners. The casters 5 facilitate the movement and handling of the cold storage body 1, improving its flexibility.
