Description

Technology Field

[0001] The present invention relates to a seafood freezing storage management system, and more specifically, to a seafood freezing storage management system designed to detect storage environment factors such as temperature, humidity, and cold air flow in real time in a freezing environment where seafood is stored for a long period, and to automatically adjust the operation of a refrigerator, dehumidifier, blower, and defrosting device accordingly. Background Technology

[0003] Since seafood has a long distribution period from production to consumption and quality can deteriorate rapidly if frozen conditions are not maintained, ensuring stability in temperature, humidity, and airflow during storage is crucial.

[0004] Generally, seafood freezing facilities have relied on simple freezing devices, and often lacked complex sensor systems to detect changes in the internal environment in real time, or control logic to automatically adjust freezing equipment according to changed environmental conditions.

[0005] In particular, during frozen storage, thermal non-uniformity can easily occur depending on the type of seafood, stacking height, and packaging type, and problems may arise where internal airflow becomes unbalanced depending on the periodic operation conditions of the freezer and the number of times the door is opened and closed.

[0006] If such environmental variations persist for a certain period, temperature increases, uneven freezing, and excessive humidity fluctuations may occur, leading to a rapid deterioration in the quality of seafood.

[0007] In addition, the accumulation of condensation, frost, and ice inside the freezer reduces the heat exchange efficiency of the chiller, leading to increased power consumption in the long term and acting as a factor that lowers storage efficiency.

[0008] Some existing storage systems control freezers by simply turning them on and off based on a single sensor value, which limits their ability to respond to complex environmental changes or detect quality deterioration in advance.

[0009] Since there are many cases where quality recovery becomes impossible if a sudden temperature rise or uneven cold transfer persists for just a few hours during seafood storage, there is a need to combine high-precision environmental sensing technology with prediction-based automatic control technology.

[0010] In addition, an alarm system is required to minimize on-site response time by promptly notifying managers of potential quality anomalies during storage; however, existing simple alarm methods have the problem of making rapid response difficult because they fail to provide sufficient situational information.

[0011] Therefore, a new type of management system is required that integrates real-time detection of the cold storage environment, automatic control of refrigerators, dehumidifiers, fans, and defrosting devices, and early detection and alarm functions for potential quality abnormalities.

[0012] Meanwhile, the aforementioned background technology is technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot necessarily be considered publicly known technology disclosed to the general public prior to the filing of the present invention.

Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0036] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0037] FIG. 1 is a drawing showing a seafood freezing storage management system according to one embodiment of the present invention.

[0038] Referring to FIG. 1, a seafood freezing storage management system (10) according to one embodiment of the present invention includes a freezing storage room (100) and an environment sensor module (200).

[0039] The frozen storage room (100) is a structure that provides a frozen storage space for long-term storage of seafood (1), and is composed of a storage space with enhanced insulation performance so that the internal temperature, humidity, airflow, etc., can be stably blocked from the external environment.

[0040] The cold storage room (100) may be provided with an internal structure that can maintain internal thermal uniformity to minimize factors that may cause quality degradation during long-term storage of seafood (1), and may be manufactured in a shape that allows for uniform cold air transfer even when seafood of various sizes or packaging types are stacked or dispersed.

[0041] The cold storage room (100) may include a shielding structure that can minimize external temperature changes, internal air flow due to door opening and closing, and cold air loss, thereby further improving the freshness and storage efficiency of the seafood (1).

[0042] The environment sensor module (200) is composed of at least one type of sensor that detects at least one of the internal temperature, humidity, and air circulation status of the cold storage room (100), and can be configured by combining a plurality of sensors to accurately detect the real-time status of the cold storage room (100).

[0043] The environment sensor module (200) can be designed to quickly detect when a change in the internal environment of the cold storage room (100) exceeds a threshold that may affect the long-term storage of the seafood (1), and to be linked with a subsequent control or warning system.

[0044] The environment sensor module (200) has the advantage of being able to quickly detect even minute environmental changes, as the sensor can be installed at various locations such as the top, bottom, entrance, and center of the cold storage room (100).

[0045] The environment sensor module (200) may include a waterproof and cold-resistant cover to prevent contamination and condensation of the sensor, and thus has a structural advantage of being able to operate stably and continuously even in a low-temperature environment.

[0046] A seafood freezing storage management system (10) according to one embodiment of the present invention having the configuration described above can detect and manage environmental factors such as temperature rise, humidity change, and air stagnation that may occur while seafood (1) is stored for a long period of time in real time, thereby maximizing the effect of maintaining the quality and preserving the freshness of seafood (1).

[0047] In addition, by ensuring the stability of the frozen storage environment based on information collected through the environmental sensor module (200), the risk of quality degradation, spoilage, dehydration, etc., which may occur during long-term storage can be minimized, and technical advantages can be provided to increase the reliability of storage of seafood (1) in various storage environments.

[0049] A seafood freezing storage management system (10) according to one embodiment of the present invention having the configuration as described above may further include a freezing environment control unit (300) and a quality abnormality notification unit (400).

[0050] The refrigeration environment control unit (300) is configured to automatically control the operation of a refrigerator, dehumidifier, blower, or defrosting device of a refrigeration storage room (100) based on environmental data collected from an environment sensor module (200).

[0051] The refrigeration environment control unit (300) can operate to ensure thermal uniformity of the storage space by immediately adjusting the output or operating cycle of the refrigeration unit when the temperature change inside the refrigeration storage room (100) deviates from the set reference value.

[0052] The refrigeration environment control unit (300) can control the control level of the dehumidifier in stages to maintain humidity balance when humidity increases and the risk of surface freezing or moisture evaporation of the seafood (1) increases.

[0053] The refrigeration environment control unit (300) can control the airflow or direction of the blower when an area where the air inside the refrigeration storage room (100) is stagnant is detected, thereby facilitating air circulation and eliminating deviations in the distribution of cold air.

[0054] The refrigeration environment control unit (300) can automatically determine the defrosting cycle and activate the defrosting device when necessary, and can perform a defrosting optimization function to prevent the refrigeration efficiency from decreasing due to excessive frost and freezing.

[0055] The refrigeration environment control unit (300) may include rule-based or statistical-based logic that predicts the state of the refrigeration storage room (100) based on correlation analysis between collected sensor data and adjusts a pre-emptive operation mode according to the prediction result.

[0056] The quality abnormality notification unit (400) is configured to provide a warning signal to an administrator terminal when the possibility of quality deterioration of the seafood (1) stored in the frozen storage room (100) is detected, thereby performing the role of preventing quality deterioration by detecting changes in the condition of the seafood (1) at an early stage.

[0057] The quality abnormality notification unit (400) can immediately generate a notification signal when it determines a situation in which there is a possibility of quality deterioration, such as a sudden rise in temperature, a sudden change in humidity, uneven airflow, or an abnormal long-term shutdown of the refrigerator.

[0058] The quality abnormality notification unit (400) includes time information, location information where the abnormal condition occurred, and the amount of change in sensor data when the notification signal is transmitted to the manager terminal, so that the manager can quickly identify the situation on site.

[0059] The quality abnormality notification unit (400) may include reliability assurance functions such as duplicate transmission, retransmission after storage, and transmission failure recording so that the notification is not missed even in the event of a terminal connection failure or network congestion.

[0060] The quality abnormality notification unit (400) has the effect of improving management efficiency by automating an alarm system to stably maintain the quality of seafood (1) stored for a long period in a frozen storage room (100).

[0061] A seafood freezing storage management system (10) according to one embodiment of the present invention having the configuration described above analyzes the internal environment of a freezing storage room (100) in real time and automatically adjusts the operation of a freezer, dehumidifier, blower, and defrosting device according to the analysis results, thereby having the effect of greatly improving the stability of the storage environment.

[0062] In addition, by detecting the possibility of quality deterioration of the seafood (1) at an early stage and immediately transmitting it to the manager terminal, the risk of quality degradation or disposal is minimized, and the overall operational efficiency and safety of the seafood storage system are simultaneously increased, providing a technical advantage.

[0063] The combination of the freezing environment control unit (300) and the quality abnormality notification unit (400) contributes to enhancing the reliability of the overall storage environment by going beyond simply detecting environmental changes in the freezing storage room (100) to include active and automated environment management and a prediction-based alarm system.

[0065] FIGS. 2 and FIGS. 3 are drawings showing a seafood freezing storage management system according to another embodiment of the present invention.

[0066] Referring to FIGS. 2 and 3, a seafood freezing storage management system (20) according to another embodiment of the present invention includes a freezing storage room (100), an environment sensor module (200), and a cold air injection module (500).

[0067] Here, the cold storage room (100) and the environment sensor module (200) are identical to the components of FIG. 1, so the description is omitted to avoid duplication of description.

[0068] A plurality of cold air injection modules (500) are installed sequentially along the upper side of the cold storage room (100) and are configured to sequentially receive cold air from a cooling device (110) installed in the cold storage room (100) and uniformly spray it into the internal space of the cold storage room (100).

[0069] The cold air injection module (500) may include an internal flow equalization structure so that cold air supplied from the cooling device (110) can be distributed to each module in equal proportions as it moves sequentially along the passage.

[0070] The cold air injection module (500) is positioned at the top of the cold storage room (100) and utilizes the existing cold environment characteristics in which cold air naturally diffuses from the top to the bottom, thereby ensuring thermal uniformity throughout the storage space.

[0071] The cold air injection module (500) can be configured in such a way that the injection amount for each module can be individually adjusted, thereby allowing for fine correction of temperature deviations that may occur in specific areas of the cold storage room (100).

[0072] The cold air injection module (500) can be designed to maintain a uniform spacing between modules and optimize the injection angle and direction so that the cold air reaches evenly to the bottom even when the seafood (1) is stored in stacks.

[0073] The cold air injection module (500) can be manufactured with a material and shape with an optimized heat transfer surface area to prevent freezing and condensation that may occur during long-term operation, and can be configured with a modular structure for ease of maintenance.

[0074] The cold air injection module (500) can perform the function of increasing environmental stability by automatically adjusting the amount of injection by modules adjacent to the area when a cold air shortage is detected in a specific area inside the cold storage room (100).

[0075] A seafood freezing storage management system (20) according to another embodiment of the present invention can minimize the overall temperature variation of the freezing storage room (100) by uniformly spraying cold air delivered from a cooling device (110) through a plurality of modules, and effectively suppress the possibility of quality degradation occurring during the long-term storage process of seafood (1).

[0076] In addition, by configuring the cold air injection module (500) in multiple units, fine adjustment of the cold air distribution becomes possible, and a technical advantage is provided that more precise refrigeration environment control is possible by quickly correcting temperature abnormalities or heat concentration phenomena in specific areas.

[0077] Furthermore, the arrangement and structural combination of the cold air injection module (500) improves the overall energy efficiency of the cold storage room (100), and as the cold air transfer efficiency improves, it reduces the load of the refrigeration unit, thereby contributing to increasing the lifespan and stability of the entire system.

[0080] Referring to FIG. 4, the cold air injection module (500) includes a horizontal moving rail (510), a horizontal moving part (520), a module installation groove (530), a spherical module (540), a module rotation driving part (550), a cold air delivery channel (560), a hollow chamber (C), a first injection path (570), a second injection path (580), a third injection path (590), and an opening / closing control part (600).

[0081] The horizontal moving rail (510) is configured to extend in the left-right width direction along the upper side of the cold storage room (100) and serves as a guide to provide the overall movement trajectory of the cold air injection module (500).

[0082] The horizontal moving rail (510) can be designed so that the horizontal moving part (520) can slide smoothly even during long-term use by having a friction-reducing treatment on the rail surface.

[0083] The horizontal moving rail (510) may be treated with anti-corrosion, moisture-proof coating, or anti-freezing structure so that it can be stably maintained even with internal temperature fluctuations or condensation formation in the cold storage room (100).

[0084] The horizontal moving part (520) is configured to be capable of sliding movement on the horizontal moving rail (510), and provides physical movement force that allows the cold air injection module (500) to move to a required position.

[0085] The horizontal moving part (520) is designed so that the connection structure with the rail does not shake, ensuring stable movement even against vibrations or repeated cooling shocks that may occur during cold air injection.

[0086] The horizontal moving part (520) may be applied in a way that automatically adjusts its position to a specific zone according to the operating mode of the cooling device (110), thereby improving the concentration or dispersion effect of the cold air supply.

[0087] The module installation groove (530) is formed hollowly on the inner side of the horizontal moving part (520), and the lower side of the hollow structure forms an opening to provide a space where the spherical module (540) can rotate or tilt.

[0088] The module installation groove (530) can have a smooth air passage formed so that cold air delivered from the cooling device (110) can efficiently pass through the interior, and an insulating structure can be added to reduce cold air loss.

[0089] The module installation groove (530) is configured with a structure in which the inner surface is precisely machined so that the spherical module (540) can maintain uniform rotational movement, and can be designed so that wear is minimized even during long-term use.

[0090] The spherical module (540) is configured to be rotatably installed in the module installation groove (530) in a circular spherical shape and performs the function of directly spraying cold air through the internal hollow chamber (C).

[0105] The second injection chamber (580) serves to diffuse cooling the surrounding area after the central injection, thereby enabling a uniform supply of cold air over a wide area.

[0106] The third injection tube (590) is formed in a circular arrangement with a larger diameter than the second injection tube (580) and performs an outer injection function to spread cold air over a wide area.

[0107] The third injection tube (590) has the effect of increasing the uniformity of cold air throughout the entire cold storage room (100) by naturally delivering cold air to the area where low-pressure cold air diffusion is required.

[0108] The opening / closing control unit (600) is configured to open and close the second injection path (580) and the third injection path (590), and performs the role of controlling the cold air injection pattern and injection area.

[0109] The opening / closing control unit (600) has the function of automatically opening / closing according to the analysis of the temperature distribution of the cold storage room (100) and switching to a cold air concentration or cold air diffusion mode.

[0110] The opening / closing control unit (600) can implement an active cold air control system that quickly corrects the cold air shortage in a specific area in conjunction with the received sensor data.

[0111] A cold air injection module (500) according to one embodiment of the present invention having the configuration described above can concentrate, diffuse, and disperse cold air through the structure of rotation and multiple injection of a spherical module (540), thereby providing excellent cooling efficiency that enhances temperature uniformity inside a cold storage room (100).

[0112] In addition, by utilizing the horizontal moving rail (510) and the horizontal moving part (520), the cold air injection position can be freely adjusted, allowing for flexible cold air operation that responds to changes in storage volume and loading method.

[0113] Furthermore, the cold air delivery channel (560) and the hollow chamber (C) stabilize the cold air pressure and flow, ensuring a uniform supply of cold air to each injection point, thereby having the technical advantage of maintaining a constant cold air quality even during long-term use.

[0131] The second rotary motor (650) may be designed with high durability and cold resistance so that stable operation is achieved even when the cold air injection pattern changes frequently.

[0132] The second opening / closing cover (660) is configured in a downwardly rounded arch shape that covers all of the openings formed on the lower side of the first opening / closing cover (620) where the first injection path (570) and the second injection path (580) are located.

[0133] The second opening / closing cover (660) can distribute internal cold air evenly when rotating due to its arch-shaped structural characteristics, and allows for stable opening of cold air even at low pressure.

[0134] The second opening / closing cover (660) can continuously adjust the opening amount of the spray according to the rotation of the second rotary motor (650), which is advantageous for precisely controlling the cold air spray intensity.

[0135] The second cover support (670) is installed between the drive shaft of the second rotary motor (650) and the second opening / closing cover (660) to stably join the second opening / closing cover (660) and support rotational movement.

[0136] The second cover support (670) may have a left-right balance structure or a cushioning structure applied to suppress eccentricity or vibration that occurs during rotation.

[0137] The second opening groove (680) is a plurality of opening areas formed in the second opening / closing cover (660), which controls the opening of the second injection path (580) to adjust the diffuse cold air injection pattern.

[0138] The second open groove (680) may include a patterned groove or a variable angle structure that can adjust the cold air injection direction distribution, thereby enabling various cold air injection scenarios.

[0139] The third opening groove (690) is an open area formed in the first opening / closing cover (620) and serves to control the opening of the first injection path (570).

[0140] The third open groove (690) is designed to finely adjust the cold air injection intensity for areas requiring concentrated cooling.

[0141] An opening / closing control unit (600) according to one embodiment of the present invention having the configuration as described above,

[0142] It has a structural advantage of being able to precisely control the cold air injection pattern by independently and continuously opening and closing the first injection chamber (570), the second injection chamber (580), and the third injection chamber (590).

[0143] In addition, the amount of cold air sprayed and the range of cold air diffusion can be automatically adjusted according to the situation through a combination of multiple rotary motors (610, 650) and multiple opening / closing covers (620, 660), so that the temperature difference inside the cold storage room (100) can be effectively corrected.

[0144] Furthermore, the internal structure of the opening / closing control unit (600) is designed to minimize cold air loss and improve spraying efficiency, thereby providing an environment that can stably maintain the quality of the seafood (1) even during long-term storage.

[0146] Figure 8 is a drawing showing the module rotation drive unit of Figure 5.

[0147] Referring to FIG. 8, the module rotary drive unit (550) includes a drive unit installation groove (551), a curved frame (552), a rotary drive gear (553), a support projection (554), and a projection support (555).

[0148] The drive unit installation groove (551) is a configuration formed on the upper side of the module installation groove (530) and provides a space in which a curved frame (552) and a rotary drive gear (553) can be placed.

[0149] The drive unit installation groove (551) can be precisely machined into a structure with an inner surface having a curvature, serving to guide the curved frame (552) to move smoothly in a curved manner.

[0150] The drive unit installation groove (551) can be made of a material with enhanced cold resistance and durability so that deformation does not occur even in the low-temperature environment of the cold storage room (100).

[0151] The curved frame (552) is formed by bending it into a round shape and is configured to be installed on one side of the drive unit installation groove (551) so as to be able to move in a curved manner.

[0152] The curved frame (552) is positioned to wrap around the upper side of the spherical module (540) and serves to stably hold the rotating structure.

[0153] The curved frame (552) moves along the curved surface according to the rotation of the rotary drive gear (553), and can finely adjust the rotation angle of the spherical module (540) during the movement process.

[0154] The curved frame (552) can be surface-treated and bearing-structured to minimize internal friction, so that performance is maintained consistently even during repeated operation for a long time.

[0155] The rotary drive gear (553) is configured to rotate in the forward or reverse direction to move the curved frame (552) in a curved motion.

[0156] The rotary drive gear (553) can be designed to enable precise rotational control by being directly coupled to the drive motor or linked with the reduction gear structure.

[0157] The rotary drive gear (553) acts as a key driving element that determines the overall direction of the spherical module (540) as the rotational speed and amount of rotation are controlled, and increases the precision of the cold air injection direction.

[0158] The support projection (554) is a component installed in the upper central part of the spherical module (540) exposed to the drive unit installation groove (551), and is a coupling element that is directly affected by the movement of the curved frame (552).

[0159] The support projection (554) serves to stably hold the rotational center axis of the spherical module (540) and prevents eccentricity occurring during rotation, thereby increasing injection accuracy.

[0160] The support projection (554) can control the tilt and rotation angle of the spherical module (540) by receiving rotational force between the curved frame (552) and the projection support (555).

[0161] The protrusion support (555) is configured to be installed on the inward surface of the curved frame (552) to support the support protrusion (554).

[0162] The protrusion support (555) serves to rotate the support protrusion (554) smoothly and stably as the curved frame (552) moves along the curved surface.

[0163] The protrusion support (555) has the technical effect of maintaining the injection direction precisely because it balances the axis so that it does not shake when the spherical module (540) rotates.

[0164] The protrusion support (555) may include a structural cushioning function to alleviate friction and shock occurring during operation and to maintain rotational stability even during long-term operation.

[0165] In one embodiment, the projection support (555) may be made of an actuator capable of extending or contracting.

[0166] The protrusion support (555) performs the function of tilting or stably supporting the upper central axis of the spherical module (540) while changing the position of the support protrusion (554) according to the extension or contraction movement of the actuator.

[0167] The protrusion support (555) may include a driving structure based on fine step control to enable precise tilting control, thereby allowing fine adjustment of the rotation angle of the spherical module (540) and the direction of cold air injection.

[0168] The protrusion support (555) may have a cushioning function or an earthquake-resistant structure to mitigate rotational shock or eccentric force occurring during the tilting process of the spherical module (540).

[0169] The protrusion support (555) may be composed of a driving cylinder, an electric actuator, or a micro linear actuator, etc., with enhanced cold resistance so that it can operate stably even in a low-temperature environment.

[0170] The protruding support (555) has the technical effect of enabling the up-down and left-right adjustment of the cold air spray angle through the tilting control of the spherical module (540), thereby allowing for more precise correction of the temperature deviation in a specific area of ​​the cold storage room (100).

[0171] A protrusion support (555) according to one embodiment of the present invention having the configuration described above can precisely control the tilting of a spherical module (540) through the driving of an actuator that extends or contracts, and provides the technical advantage of enabling multi-axis control of the cold air injection direction.

[0172] In addition, by finely adjusting the tilting angle of the spherical module (540), the cold air concentration area and cold air diffusion range of the cold air injection module (500) can be changed according to the situation, so that the temperature balance inside the cold storage room (100) can be adjusted immediately.

[0173] Furthermore, the actuator-based tilting structure has minimal deformation even with repeated movements and is suitable for long-term operation in a refrigerated environment, contributing to increased stability and uniformity of the entire cold air injection system.

[0174] A module rotation drive unit (550) according to one embodiment of the present invention having the configuration described above provides a mechanical advantage of being able to precisely adjust the rotation direction and tilt of a spherical module (540) through the interaction of a curved frame (552) and a rotation drive gear (553).

[0175] In addition, the combination of the support projection (554) and the projection support (555) stably maintains the rotational center of the spherical module (540), thereby contributing to reducing deviation in the cold air injection direction and improving injection efficiency.

[0176] Furthermore, the entire mechanism of the module rotation drive unit (550) has structural and technical advantages that can more precisely correct the internal temperature deviation of the cold air injection module (500) by enhancing the direction control performance of the cold air injection module (500).
