Description

Technical Field

[0001] The utility model relates to the technical field of mushroom freezing and refrigeration equipment, in particular to an intelligent preservation device for edible mushrooms. Background Art

[0002] Edible mushrooms, such as button mushrooms, are difficult to preserve. Without proper storage, their shelf life typically does not exceed three days. Therefore, refrigeration is essential for long-term storage. As a crucial component of the mushroom cold chain, refrigerated storage effectively mitigates mushroom loss and maintains their fresh taste and flavor.

[0003] The preservation of edible mushrooms has very strict requirements for temperature, humidity, and carbon dioxide concentration. Traditionally, mushroom storage and transportation involves farmers picking the mushrooms, wrapping them in plastic wrap, and then delivering them to consumers or restaurants through markets or fruit and vegetable supermarkets. In fruit and vegetable supermarkets, restaurants, and homes, mushrooms are typically stored directly in refrigerators or freezers for low-temperature preservation. Because traditional refrigerators or freezers can only adjust temperature and lack intelligent functions such as detecting, monitoring, and adjusting the temperature, humidity, and carbon dioxide concentration within the cabinet, they cannot effectively ensure the freshness of edible mushrooms and store them for a long time. There are also existing preservation devices that can achieve functions such as moisturizing, such as a humidifying device for an intelligent mushroom cloud cabinet provided by Chinese Patent Publication No. CN209563281U and a long-term fresh-keeping and preservation device provided by Chinese Patent Publication No. CN217523811U. Although these devices can better preserve mushrooms compared to traditional refrigerators or freezers, they still cannot meet modern usage requirements in some environments with extremely high freshness requirements.

[0004] Therefore, there is an urgent need in the prior art to invent an intelligent preservation device suitable for edible mushrooms. Utility Model Content

[0026] In summary, the intelligent preservation device for edible mushrooms provided by the present invention has at least the following technical effects compared to the prior art:

[0027] 1) The fresh-keeping device of the present invention is equipped with a humidification system, which includes a humidification device, a first fan assembly, and a second fan assembly. The humidification device includes a water storage container and humidification cotton. The water storage container is filled with water and contains a plurality of humidification cottons. When the humidity in the storage chamber is detected to be lower than a preset value, the humidification cottons absorb water. The first fan assembly blows air to the humidification cottons to blow out the moisture in the humidification cottons. The blown water vapor flows upward under the suction force of the second fan assembly, causing the water vapor to be evenly diffused throughout the storage chamber, thereby effectively increasing the humidity in the storage chamber and maintaining the same humidity between each shelf, ensuring that the humidity in the storage chamber meets the preservation requirements of edible mushrooms.

The air inlet is used to introduce oxygen into the storage chamber, and the air outlet is used to expel carbon dioxide from the storage chamber. When the carbon dioxide concentration in the storage chamber is detected to exceed a preset value, an external oxygen supply device introduces oxygen into the storage chamber through the upper air inlet. The carbon dioxide in the storage chamber, which has a higher density than oxygen, sinks and is expelled through the lower air outlet. This achieves ventilation, effectively reducing the carbon dioxide concentration in the storage chamber and ensuring that the growth and storage conditions of edible mushrooms are within the most suitable carbon dioxide concentration range.

[0029] 3) The present invention's preservation device controls the humidity, carbon dioxide concentration, and temperature in the storage chamber through a humidification system, a ventilation system, and a refrigeration system. In addition to achieving preservation, the device can also adjust the growth cycle or preservation period of edible mushrooms by controlling temperature, humidity, and carbon dioxide concentration, thereby achieving different preservation effects in different usage scenarios. For example, the temperature, humidity, and carbon dioxide concentration are controlled based on the amount of food consumed, ensuring that there are sufficient and fresh mushrooms available during meals. After consumption, the temperature, humidity, and carbon dioxide concentration are adjusted to ensure that the mushrooms grow to the optimal state for the next consumption. This allows the preservation device to meet the diverse needs of different scenarios and is highly intelligent. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They 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 direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] See also Figure 1-Figure 3 As shown, according to an embodiment of the present invention, the intelligent preservation device for edible mushrooms includes a cabinet 1 and a refrigeration system 3. The cabinet 1 is provided with an inner container 2, and the inner container 2 is provided with a storage chamber 21. The storage chamber 21 is used to store edible mushrooms and other foods. The refrigeration system 3 is used to control the temperature in the storage chamber 21 to ensure that the food stored in the storage chamber 21 is kept in the best fresh state.

[0040] The intelligent preservation device for edible mushrooms also includes a humidification system 4, which includes a humidification device and a first fan assembly arranged at the bottom of the inner tank 2, and a second fan assembly arranged at the top of the inner tank 2. The airflow direction of the first fan assembly is toward the humidification device, and the airflow direction of the second fan assembly is toward the top or obliquely upward. Specifically, when the humidification system 4 starts working, the first fan assembly is in operation, and the wind it blows will bring the water vapor in the humidification device into the storage chamber 21, thereby increasing the humidity of the storage chamber 21. In addition, when the second fan assembly is in operation, the air in the storage chamber 21 can be extracted, and the suction effect generated causes the water vapor in the humidification device to flow upward, thereby evenly diffusing the water vapor throughout the storage chamber 21, thereby effectively increasing the humidity of the storage chamber 21 and avoiding the concentration of water vapor in the bottom area of ​​the storage chamber 21, ensuring that the humidity of the entire storage chamber 21 meets the preservation conditions of edible mushrooms.

[0041] The intelligent preservation device for edible mushrooms also includes a ventilation system 5, which includes an air inlet 51 provided at the top of the inner container and an air outlet 52 provided at the bottom of the inner container, and the air inlet 51 and the air outlet 52 are both connected to the storage chamber 21. The air inlet 51 is used to introduce oxygen into the storage chamber 21, and the air outlet 52 is used to discharge carbon dioxide in the storage chamber 22. When the ventilation system 5 is started, oxygen is introduced into the storage chamber 21 through the upper air inlet 51, and the carbon dioxide in the storage chamber 21, which has a higher density than oxygen, sinks and is discharged through the lower air outlet 52, thereby achieving a ventilation effect for the storage chamber 21, effectively reducing the carbon dioxide concentration in the storage chamber, and ensuring that the growth and storage conditions of the edible mushrooms are within the most suitable carbon dioxide concentration range.

[0042] In the technical solution of this embodiment, the intelligent mushroom preservation device controls the humidity, carbon dioxide concentration, and temperature of the storage chamber 21 through a humidification system 4, a ventilation system 5, and a refrigeration system 3. In addition to achieving the preservation function, the device can also adjust the growth cycle or preservation period of the mushrooms by controlling the temperature, humidity, and carbon dioxide concentration, thereby achieving different preservation effects in different usage scenarios. For example, in a restaurant dining scenario, the temperature, humidity, and carbon dioxide concentration can be controlled according to the amount of mushrooms consumed, ensuring that consumers have sufficient and fresh mushrooms to eat. After consumption, the temperature, humidity, and carbon dioxide concentration are adjusted to ensure that the mushrooms grow to the optimal freshness state for the next consumption. This allows the preservation device to meet the different usage needs of different scenarios and has a high degree of intelligence.

[0043] Example 1

[0044] In an optional embodiment of the present invention, a technical solution for the internal space design and control system design of the storage chamber 21 is disclosed.

[0045] See also Figure 1 As shown, in the technical solution of this embodiment, the storage chamber 21 is equipped with multiple shelves 22 arranged in a vertically spaced sequence. The shelves 22 divide the storage chamber 21 into multiple storage spaces. Shelves 22 are used to store food such as mushrooms. The multiple shelves 22 divide the storage chamber 21 into multiple storage spaces, allowing different food types to be placed according to different conditions. Furthermore, due to the suction effect of the second fan assembly, the water vapor generated by the humidifier is evenly distributed within the storage chamber 21, that is, evenly distributed throughout each storage space, ensuring equal humidity conditions in each storage space.

[0046] Furthermore, each storage space is equipped with at least one temperature sensor 6, one humidity sensor 7, and one carbon dioxide detector 8 on the inner wall of the inner container 2 and / or the shelf 22. The temperature sensor 6 is used to detect the temperature in each storage space, the humidity sensor 7 is used to detect the humidity in each storage space, and the carbon dioxide detector 8 is used to detect the carbon dioxide concentration in each storage space. Preferably, the temperature sensor 6, humidity sensor 7, and carbon dioxide detector 8 corresponding to each storage space are installed on the inner wall of the storage space, which facilitates installation and wiring to the external control module.

[0047] Further, see Figure 4 As shown, the intelligent preservation device for edible mushrooms also includes a control module 9, which is electrically connected to the temperature sensor 6, the humidity sensor 7, and the carbon dioxide detector 8, and is also electrically connected to the refrigeration system 3, the humidification system 4, and the ventilation system 5. Specifically, the control module 9 is used to receive the temperature, humidity, and carbon dioxide concentration signals emitted by the temperature sensor 6, the humidity sensor 7, and the carbon dioxide detector 8, and compare the detected signal values ​​with preset values. When the values ​​exceed or fall below the preset values, the control module 9 sends corresponding signals to the refrigeration system 3, the humidification system 4, and the ventilation system 5 to control them to be turned on or off. In addition, the number of control modules 9 can be one, in which case the control module 9 is a central control module. The number of control modules 9 can also be three or more, in which case the control module includes at least a temperature control module, a humidity control module, and a carbon dioxide control module, corresponding to different sensors and systems respectively.

[0048] Example 2

[0049] In another optional embodiment of the present invention, a technical solution for the specific structural design of the humidification system 4 is disclosed.

[0050] See also Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the humidifying device includes a water storage container 41 and humidifying cotton 42. The water storage container 41 is arranged at the bottom of the inner container 2. A plurality of humidifying cottons 42 are spaced apart in the water storage container 41. The humidifying cottons 42 are preferably square in structure. The plurality of humidifying cottons 42 are placed upright on the water storage container 41 at such intervals. The bottoms of the humidifying cottons 42 are in contact with the water in the water storage container 41. After absorbing water, the water fills the entire humidifying cotton 42. After the water is dried, the humidifying cotton 42 can absorb water again and fill the humidifying cotton 42.

[0051] See also Figure 1 and Figure 2As shown, in a preferred solution of this embodiment, the first fan assembly includes a first mounting bracket 43 and a plurality of first fans 44. The first mounting bracket 43 is arranged on the rear side wall of the bottom of the inner tank 2, and the first fans 44 are arranged on the first mounting bracket 42, and the first fans 44 are arranged toward the humidifying cotton 42. When the first fans 44 are started, the airflow blown out by them can blow out the moisture in the humidifying cotton 42 and diffuse the water vapor in the storage chamber 21. Among them, the first mounting bracket 43 is used to provide support for the installation of the first fans 44. It is arranged on the rear side wall of the bottom of the inner tank 2. Firstly, it can enhance the diffusion capacity of the water vapor in the storage chamber 21 through the blowing force, and secondly, it is convenient for users to perform repair, maintenance, replacement and other operations without affecting the storage space of the storage chamber 21 for mushrooms.

[0052] Further, see Figure 1 and Figure 3 As shown, the second fan assembly includes a second mounting bracket 45 and a plurality of second fans 46. The second mounting bracket 45 is mounted on the rear side wall of the top of the inner liner 2. The second fans 46 are mounted on the second mounting bracket 45, and the second fans 46 are tilted toward the storage chamber 21. When the second fans 46 are activated, the suction generated causes the water vapor blown out of the humidifying cotton 42 to flow upward, thereby evenly diffusing the water vapor throughout the storage chamber 21. This effectively increases the humidity in the storage chamber 21 and prevents the water vapor from concentrating in the bottom area of ​​the storage chamber 21, ensuring that the humidity throughout the storage chamber 21 meets the preservation requirements for edible mushrooms. Similarly, the second mounting bracket 45 is used to provide support for the installation of the second fans 46. Positioning it on the rear side wall of the top of the inner liner 2 can, firstly, enhance the diffusion capacity of water vapor in the storage chamber 21 through the suction generated, and secondly, facilitate user repair, maintenance, and replacement operations without affecting the storage space of the storage chamber 21 for the mushrooms.

[0053] Further, see Figure 1 and Figure 3 As shown, the humidification system 4 further includes a back plate 47 connected to the second mounting bracket 45 and extending downward. An air duct 48 is provided between the second mounting bracket 46, the back plate 47, and the rear side wall of the inner liner 2. The bottom of the air duct 48 is connected to the storage chamber 21. When the second fan 46 is activated, the air in the storage chamber 21 is drawn into the air duct 48 and then flows back into the storage chamber 21 through the opening at the bottom of the air duct 48, forming an air circulation system, so that the water vapor blown out of the humidification cotton 42 at the bottom is evenly diffused throughout the storage chamber 21.

[0054] Example 3

[0055] In another optional embodiment of the present invention, a technical solution for the specific structural design of the ventilation system 5 is disclosed.

[0056] See also Figure 2 and Figure 3As shown, in the technical solution of this embodiment, the ventilation system 5 also includes an oxygen supply device, an air inlet pipe, and an air outlet pipe. The two ends of the air inlet pipe are respectively connected to the oxygen supply device and the air inlet 51, and the air outlet pipe is connected to the air outlet 52. Specifically, the oxygen supply device is used to generate oxygen and pass it into the storage chamber through the air inlet pipe and the air inlet 51. After the oxygen is introduced, the carbon dioxide in the storage chamber 21, which has a higher density than oxygen, sinks and is discharged through the air outlet 52 below and the air outlet pipe, thereby achieving a ventilation effect, effectively reducing the carbon dioxide concentration in the storage chamber, and ensuring that the growth and storage conditions of edible mushrooms are within the most suitable carbon dioxide concentration range.

[0057] Example 4

[0058] In another optional embodiment of the present utility model, a technical solution for a specific structural design of the refrigeration system 3 is disclosed.

[0059] In an alternative embodiment of this embodiment, the refrigeration system 3 includes a compressor, an evaporator, a condenser, and a throttling element. The evaporator and condenser are located on the inner and outer sides of the storage chamber 21, respectively, and the compressor can be installed at the bottom of the inner tank 2. The compressor, evaporator, condenser, and throttling element are connected by pipes to form a refrigerant circulation channel. The evaporator is used to exchange heat with the air in the storage chamber 21, thereby reducing the temperature in the storage chamber 21 and achieving a low-temperature preservation effect.

[0060] In another alternative embodiment of this embodiment, the refrigeration system 3 includes a semiconductor chip, a cooling structure connected to the cold end of the semiconductor chip, and a heat dissipation structure connected to the hot end of the semiconductor chip. The cooling structure and the heat dissipation mechanism are respectively located on the inner and outer sides of the storage chamber 21. The cooling structure may include a cooling plate, a cooling fan, and other structures for exchanging heat with the air in the storage chamber 21, thereby lowering the temperature in the storage chamber 21 and achieving a low-temperature preservation effect.
