Abstract
Description
Technical Field
[0001] This utility model relates to the field of blueberry storage technology, and in particular to a blueberry preservation device. Background Technology
[0002] Blueberries, as a highly nutritious fruit, have become increasingly popular with consumers in recent years. However, as a fresh fruit, blueberries require preservation during storage. The storage temperature should be maintained between 0℃ and 5℃, and the humidity between 90% and 95%. At the same time, it's important to avoid soaking the blueberries in water generated during refrigeration.
[0003] Currently, the traditional method of preservation often uses common refrigerators or freezers for freshness. This makes blueberries susceptible to being soaked in condensation that occurs when the door is opened and closed during storage, which can lead to the growth of fungi on the surface of the blueberries and even rot and spoilage.
[0004] Therefore, it is necessary to develop a new blueberry preservation device to solve the problems existing in the current blueberry storage process. Utility Model Content
[0005] This utility model aims to solve at least one of the technical problems existing in the prior art.
[0006] This utility model provides a blueberry preservation device, comprising:
[0007] Main unit, temperature and humidity control device, inner box and storage basket;
[0008] The main unit has an internal cavity for communication with the outside, and an external sealing door for sealing the cavity. An inner box is connected inside the cavity.
[0009] The interior of the inner box is divided into multiple storage compartments by a partition structure. The storage compartments are equipped with a support structure, a drainage channel, a ventilation channel, and a humidification pipe. The support structure is located at the bottom of the storage compartment and is used to support the storage basket. The ventilation channel is used to connect adjacent storage compartments. The drainage channel is used to drain water from the inner box. The humidification pipe is used to regulate the humidity of the storage compartment.
[0010] The temperature and humidity control device is installed on the main unit. The temperature and humidity control device cools the storage compartment by using a compressor. The temperature and humidity control device is also connected to a humidification pipe through a pipeline, and the humidity of the storage compartment is adjusted by spraying humidification through the humidification pipe.
[0011] The storage basket is equipped with a drainage hole and a ventilation hole.
[0012] As a further improvement to the above technical solution, the load-bearing structure includes multiple load-bearing bars, each of which is a cuboid, and the bottom plane of the load-bearing bar is fixedly connected to the bottom of the storage compartment.
[0013] As a further improvement to the above technical solution, the support strip extends along the direction from the sealing door to the rear panel of the main unit.
[0014] As a further improvement to the above technical solution, the drainage channel is located between the load-bearing strip and the sealing door.
[0015] As a further improvement to the above technical solution, the drainage channel runs horizontally through multiple storage compartments and through the inner box, leading to the temperature and humidity control device.
[0016] As a further improvement to the above technical solution, the humidification pipe is connected to the temperature and humidity control device, and the humidification pipe is fixedly connected to the top of the storage compartment.
[0017] As a further improvement to the above technical solution, the ventilation slot includes multiple rectangular through slots.
[0018] As a further improvement to the above technical solution, the rectangular through slot extends along the top and bottom surfaces of the storage compartment.
[0019] As a further improvement to the above technical solution, the drainage holes of the storage basket are located in the storage basket and are square.
[0020] As a further improvement to the above technical solution, the ventilation hole of the storage basket is a rectangular through hole, which is located on the side plate of the storage basket and extends along the direction from the sealed door to the rear plate of the host.
[0021] Beneficial effects: This invention, by setting a support structure in the inner box, can support the storage basket, creating a ventilation space at the bottom of the basket. This facilitates uniform cooling of the stored blueberries in multiple directions, effectively reducing losses caused by slow cooling of blueberries at the bottom in traditional refrigerators. The drainage channel drains condensate that may occur during the cooling and humidity control process, effectively reducing the growth of bacteria and fungi due to water accumulation, making the stored blueberries less prone to fermentation or rot. The ventilation channel connects horizontally adjacent storage compartments, enhancing internal airflow circulation and resulting in more uniform cooling. The humidification pipe connects to the temperature and humidity control device. When the humidity inside the storage compartment decreases, the temperature and humidity control device humidifies the storage compartment through the humidification pipe, thereby maintaining the inner box within a relatively stable humidity range. When freshly picked blueberries are placed in the blueberry preservation device, condensation will occur during the cooling process. The condensation can flow downwards through the drainage holes of the storage basket, effectively reducing internal water retention. The ventilation holes in the storage basket allow for side ventilation, ensuring the blueberries cool down quickly.

[0036] The following is combined with Figures 1 to 6 The embodiments of this utility model are described below.
[0037] This application provides a blueberry preservation device, comprising:
[0038] Main unit 100, temperature and humidity control device 200, inner box 300, and storage basket 400;
[0039] The main unit 100 has an internal cavity for communicating with the outside world, and the main unit 100 has an external sealing door for sealing the cavity. The inner box 300 is connected inside the cavity.
[0040] The interior of the inner box 300 is divided into multiple storage compartments by a partition structure. The interior of each storage compartment is equipped with a support structure 301, a drainage channel 302, a ventilation channel 303, and a humidification pipe 304. The support structure 301 is located at the bottom of the storage compartment and is used to support the storage basket 400. The ventilation channel 303 is used to connect adjacent storage compartments. The drainage channel 302 is used to drain water from the inner box. The humidification pipe 304 is used to regulate the humidity of the storage compartment.
[0041] The temperature and humidity control device 200 is installed on the main unit 100. The temperature and humidity control device 200 cools the storage compartment by means of a compressor. The temperature and humidity control device 200 is also connected to the humidification pipe 304 through a pipe, and the humidity of the storage compartment is adjusted by spraying humidification through the humidification pipe 304.
[0042] The storage basket 400 is provided with a storage basket drain hole 402 and a storage basket ventilation hole 401.
[0043] The main unit 100 is equipped with a temperature and humidity control device 200. By monitoring the temperature and humidity in the inner box 300, when the temperature or humidity reaches the preset value, the temperature and humidity control device 200 can be manually activated to adjust the temperature and humidity within a suitable range, which is beneficial to the preservation of blueberries.
[0044] Meanwhile, an inner box 300 is nested inside the cavity of the main unit 100. This is to allow the structure of the inner box to be manufactured separately during the manufacturing process for pre-assembly. Then, the inner box 300 is assembled with the main unit 100. During the assembly process, the inner box 300 is first installed into the main unit 100, and then the wiring and pipes in the inner box 300 are connected from the reserved space at the installation position of the temperature and humidity control device 200. After testing, the sealing door is installed.
[0045] In the structure of the inner box 300, the supporting structure 301 is used to support the storage basket 400, so that the bottom of the storage basket 400 forms a ventilation space, which facilitates the uniform cooling effect of the stored blueberries in multiple directions, effectively reducing the loss caused by the slow cooling of blueberries at the bottom in traditional refrigerators; the drainage channel 302 is used to drain the condensate that may occur during the cooling process and humidity control process, effectively reducing the phenomenon of bacterial and fungal growth caused by water accumulation, and the blueberries stored there are less likely to ferment or rot; the ventilation channel is used to connect the horizontally adjacent storage compartments, which can enhance the internal airflow circulation effect and make the cooling more uniform; the humidification pipe 304 is connected to the temperature and humidity control device 200. When the humidity inside the storage compartment decreases, the temperature and humidity control device 200 humidifies the storage compartment through the humidification pipe 304, thereby maintaining the inner box 300 in a relatively stable humidity range.
[0046] Furthermore, when freshly picked blueberries are placed in the blueberry preservation device, condensation will occur during the cooling process. The condensation can flow downwards through the storage basket drain hole 402 of the storage basket 400, effectively reducing the water inside. The storage basket ventilation hole 401 allows the storage basket 400 to ventilate from the side, ensuring the cooling speed of the blueberries.
[0047] The supporting structure 301 includes multiple supporting bars, each of which is a cuboid. The bottom plane of each supporting bar is fixedly connected to the bottom of the storage compartment. The cuboid supporting bars are spaced apart, and their upper surfaces directly contact the bottom of the storage basket 400, thereby effectively supporting the storage basket 400.
[0048] The support strip extends along the direction from the sealed door to the rear panel of the main unit. This orientation of the support strip reduces friction during the insertion or removal of the storage basket 400, making operation more convenient.
[0049] The drain channel 302 is located between the support strip and the sealing door. This location allows the drain channel 302 to quickly drain condensate flowing down from the sealing door, preventing bacterial growth.
[0050] The drainage trough 302 extends laterally through multiple storage compartments and through the inner box 300, leading to the temperature and humidity control device 200. The temperature and humidity control device 200 contains a wastewater tank, thereby collecting and discharging the wastewater from the drainage trough 302.
[0051] The humidifying pipe 304 is connected to the temperature and humidity control device 200, and is fixedly connected to the top of the storage compartment. The fixed connection of the humidifying pipe 304 to the top of the storage compartment allows for top-down humidification.
[0052] Ventilation slot 303 includes multiple rectangular channels. The rectangular channels provide efficient temperature and humidity exchange channels, thereby making the temperature and humidity control of two adjacent compartments more consistent, which can also improve operational efficiency to a certain extent.
[0053] The rectangular channels extend from the top to the bottom of the storage compartment. These longitudinally extending rectangular channels maximize air permeability while maintaining structural strength.
[0054] The drainage holes 402 of the storage basket are located at the bottom of the storage basket 400. The square drainage holes 402 reduce the probability that blueberries will completely block the drainage holes 402.
[0055] The storage basket ventilation hole 401 is a rectangular through hole located on the side plate of the storage basket 400 and extending along the direction from the sealed door to the rear plate of the main unit. The storage basket ventilation hole 401 is perpendicular to the rectangular through groove of the ventilation slot, thereby enabling effective ventilation after the storage basket is pushed in.
