Description

Technology Field

[0001] The present invention relates to a smart farm capable of cultivating various crops in an eco-friendly manner by utilizing a refrigerator with a transparent window. Background Technology

[0002] Shelf-type hydroponic smart farms refer to systems that artificially control the growth environment (light, air, temperature, nutrients) within artificial structures (greenhouses, buildings, etc.), enabling planned production like manufactured goods regardless of weather or season.

[0003] Depending on the light source, it is classified into artificial light type (fully controlled) and natural light combined type (partially controlled). Natural light is replaced by artificial light such as LEDs, and crops are grown vertically using a shelf system to maximize production within a confined space.

[0004] Currently, most of these farms utilize hydroponic and aeroponic systems for crop cultivation. Hydroponics involves growing crops by placing them in water containing nutrient solution, while aeroponics involves suspending the roots in the air and spraying them with nutrient solution (a mixture of water and fertilizer). In this way, smart farms reduce management costs through systems that directly supply nutrients to the crop roots.

[0005] In addition, labor costs are low due to an automated system with monitoring in all areas, designed to increase productivity, efficiency, and consistency.

[0006] The advantages of smart farm technology include the ability to produce crops year-round, achieve consistent quality and predictable yields, and utilize key resources, particularly water, efficiently.

[0007] As such, smart farms have the advantage of increasing overall farm income by enhancing efficiency and reducing labor costs. Furthermore, positive environmental effects can be expected as they can reduce greenhouse gases.

[0008] However, currently, due to a shortage of various ICT equipment and the burden of initial costs, it is difficult to implement in places such as farms, schools, salad bars, subway stations, and company cafeterias.

[0009] Korean Registered Patent No. 10-2134518, "Multipurpose Small Smart Farm Device," can be used for various purposes such as insect rearing, hydroponic cultivation of vegetables and sprout ginseng, mushroom cultivation, dryers, and cold storage, and enables the creation of an optimal environment suited to the situation. However, the Multipurpose Small Smart Farm Device has limitations in growing crops because the spacing of the shelves is not adjusted according to crop growth, and there is a problem in that it cannot cultivate crops of various sizes.

[0010] Meanwhile, the closure rate of self-employed businesses has increased due to COVID-19 and the economic recession, and the improper disposal of discarded refrigerators is causing environmental pollution. In particular, since the refrigerants in discarded refrigerators contribute to the greenhouse effect, they must be captured using appropriate equipment; however, if the cooling units are removed without proper capture, refrigerants, oils, and heavy metals flow indiscriminately into the air, soil, and rivers, posing a significant problem. To address this, measures to recycle discarded refrigerators are urgently needed. Prior art literature

[0028] First, referring to FIGS. 1 and 2, the refrigerator farm of the present invention is a device that enables the cultivation of various crops under optimal environmental conditions by utilizing existing refrigerator frames or recycling discarded refrigerators. Here, the discarded refrigerator is preferably a refrigerator in which at least one side is formed transparent so that the inside can be seen from the outside, such as commercial beverage refrigerators, wine refrigerators, or cosmetic refrigerators. This refrigerator farm allows the user to plant any crop they desire regardless of the size of the seeds, seedlings, or crops, and the light intensity is automatically adjusted according to the growth height of the crops. The refrigerator farm of the present invention may include a refrigerator (100), a shelf unit (200), a shelf moving unit (300), a cultivation module (400), a nutrient solution supply unit (500), a lighting unit (600), and a sensor unit (700).

[0029] The refrigerator (100) is configured to provide a cultivation space, and can utilize commercial beverage refrigerators, wine refrigerators, cosmetic refrigerators, etc., which have a transparent window allowing the interior to be seen. At this time, the refrigerator (100) has an air outlet (111) installed on the rear so that air at a set temperature is introduced into the interior. Such a refrigerator (100) may include a refrigerator body (110) and an installation box (120). The refrigerator body (110) is opened by a transparent door that allows the interior to be seen, forming a space for a crop to be placed inside. Additionally, the refrigerator body (110) provides an installation space for other components that allow the crop to grow automatically.

[0030] The installation box (120) is placed at the bottom or top of the refrigerator body (110) and may be equipped with a heating and cooling controller (121), a moving rail operating motor (330), a nutrient solution dispenser (550), and a water tank (560). The heating and cooling controller (121) can be used as a cooling device equipped in the existing refrigerator and as a heating device to be installed additionally, and is equipped to control the temperature inside the refrigerator body (110). As such, the heating and cooling controller (121) has an automatic temperature control function, maintains a temperature of 18 to 22 degrees, which is most suitable for crop cultivation, and allows for manual control for each crop.

[0031] The shelf section (200) is configured to allow as many crops as possible to be cultivated in a narrow space. This shelf section (200) is configured such that shelves (210) are spaced apart and installed in multiple rows within the refrigerator body (110). It is preferable that the shelf section (200) be formed in a flat shape and installed horizontally so as to support the cultivation module. Additionally, the shelf section (200) can be formed from various materials such as plastic, glass, or stainless steel. Furthermore, the shelf section (200) is equipped to be movable up and down by a shelf moving part (300), thereby allowing the distance between the shelves (210) to be adjusted.

[0032] The shelf moving unit (300) is configured to automatically adjust the spacing by moving the shelf (210) up and down. Such a shelf moving unit (300) is positioned vertically at the edge of the refrigerator body (110) and is driven simultaneously to move the shelf (210) in a vertical direction. It is preferable that the shelf moving unit (300) be formed so that the lower part of the shelf (210) is mounted and can move up and down at the same time.

[0033] For example, as illustrated in FIG. 3-(a), the shelf moving unit (300) may include a moving rail (310-1) having a rail groove (310-1a) formed in the longitudinal direction in the form of a vertical bar, and a shelf support (320-1) having a wheel (320-1a) that is positioned at the bottom of the shelf (210) and mounted on the rail groove (310-1a) to move. At this time, the shelf moving unit (300) may be connected to a moving rail operating motor (330) provided in the installation box (120) of the refrigerator (100) so that the moving rail (310-1) can be automatically driven up and down.

[0034] As another example, as illustrated in FIG. 3-(b), the shelf moving part (300) may include a moving rail (310-2) having a plurality of tooth grooves (310-2a) formed in the longitudinal direction in the form of a vertical bar, and a shelf support (320-2) having a tooth projection (320-2a) that is positioned at the bottom of the shelf (210) and moves by engaging with the plurality of tooth grooves (310-2a). In this case, the shelf moving part (300) may be connected to a moving rail operating motor (330) provided in the installation box (120) of the refrigerator (100) so that the moving rail (310-2) can be automatically driven up and down.

[0035] As another example, as illustrated in FIG. 3-(c), the shelf moving unit (300) may include a mounting base (310-3) having a plurality of connecting links (310-3a) formed in the form of a vertical bar, and a shelf support (320-3) having a mounting link (320-3a) that is positioned at the bottom of the shelf (210) and is mounted and fixed to the connecting link (310-3a). In this case, the shelf moving unit (300) may allow the mounting link (320-3a) of the shelf support (320-3) to be mounted and fixed to the connecting link (310-3a) of the mounting base (310-3) by the user, thereby allowing the installation position to be manually changed selectively.

[0036] Referring to FIGS. 2 and 4, the cultivation module (400) is configured to allow for the cultivation of seeds from the beginning by placing them in a sponge or styrofoam, or to cultivate crops by planting them in a sponge or styrofoam, and is reusable. This cultivation module (400) can be placed on a shelf (210) and may have multiple cultivation holes (412a) formed so that crops (1) can be planted. Taking into account that the upper body of a crop is large but the roots are small, cultivation holes (412a) that allow roots to enter are created, and by cultivating crops in the holes of the cultivation holes (412a) thus created, it becomes possible to cultivate crops of various sizes by placing them in the holes, rather than cultivating only specific crops by making holes in styrofoam or making only a few holes. This cultivation module (400) is reusable and can be used permanently, and has the advantage of being environmentally friendly as no waste is discharged.

[0037] In detail, the cultivation module (400) may include a cultivation module body (410), a nutrient solution inlet nozzle (420), and a nutrient solution spray nozzle (430). The cultivation module body (410) is equipped with a lower body (411) that is box-shaped and has an open top, and an upper cover (412) that is positioned on the upper surface of the lower body (411), and a plurality of cultivation holes (412a) may be formed in the upper cover (412). At this time, the cultivation module body (410) is provided such that the lower body (411) and the upper cover (412) are separable, so that after cultivating crops, cleaning is easy and the module can be reassembled for use.

[0038] The nutrient solution inlet nozzle (420) is installed on the side of the cultivation module body (410) and is configured to be connected to the nutrient solution supply unit (500). When the cultivation module (400) is installed, the nutrient solution inlet nozzle (420) is connected to the nutrient solution supply unit (500) at the corresponding location while it is placed on the shelf (210). In addition, the nutrient solution inlet nozzle (420) is configured to be easily installed and removed from the nutrient solution supply unit (500), thereby improving convenience and allowing the installation location to be easily changed, enabling the cultivation of various crops.

[0039] The nutrient solution spray nozzle (430) is installed in the direction of a plurality of cultivation holes (412a) inside the cultivation module body (410) and connected to the nutrient solution inlet nozzle (420) so as to supply nutrient solution to the plurality of cultivation holes (412a). The nutrient solution spray nozzle (430) is horizontally connected to the nutrient solution inlet nozzle (420) and arranged vertically in the direction of the cultivation holes (412a) so as to supply nutrient solution to the cultivation holes (412a) of the cultivation module body (410).

[0040] In detail, as illustrated in FIG. 4, a plurality of cultivation holes (412a) may have a crop space formed inside, and a spiral groove (412b) may be formed on the wall surface to fix the crop target in a planted state. At this time, the wall surface in which the spiral groove (412b) is formed may be a vertical structure or a slanted structure. In addition, the plurality of cultivation holes (412a) are approximately 3 to 4 cm in size, and may be larger or smaller, allowing the cultivation holes (412a) to be selected and used according to the size of the crop target.

[0041] Multiple cultivation holes (412a) are provided with a lid (412b) spirally connected to the upper portion, and a cross-shaped groove or a straight groove may be formed on the lid (412c) to be used as a handle. In this case, the cross-shaped groove or the straight groove may be used as a handle to remove the lid (412c) when the spiral groove (412b) is not on the wall. In this way, the cultivation module (400) can prevent loss by opening the lid (412c) of the cultivation hole (412a) to be used, planting the crop, and then storing the lid (412c) on the upper shelf (210) of the refrigerator (100).

[0042] Additionally, the multiple cultivation holes (412a) are equipped so that when seedlings or seeds grown in a sponge or styrofoam are placed in the crop space, they do not fall into the crop space. The multiple cultivation holes (412a) allow for the cultivation of seedlings grown in a sponge or styrofoam by placing them directly into the crop space, or for the cultivation of crops grown directly from seedlings or roots of delivered crops by placing them directly into the crop space.

[0043] The nutrient supply unit (500) is configured to supply nutrient solution to the cultivation module (400) according to the installation height of the cultivation module (400). The nutrient supply unit (500) is positioned vertically on the refrigerator (100) and is connected to the cultivation module (400) to supply nutrient solution and water from the nutrient solution dispenser (550) and water tank (560) provided in the installation box (120). This nutrient supply unit (500) may include a movable support (510), a pipe cover (520), a nutrient solution supply pipe (530), a pipe connection nozzle (540), a nutrient solution dispenser (550), and a water tank (560).

[0044] The movable support (510) can be fixedly installed by being positioned vertically on both sides of the refrigerator (100). In this way, the movable support (510) forms a guideline to allow movement in the up and down direction, thereby enabling the nutrient solution supply pipe (530) to move in a stable position.

[0045] Additionally, multiple pipe covers (520) are mounted horizontally on the movable support (510) and can be installed in multiple rows along the longitudinal direction of the movable support (510). Furthermore, the pipe covers (520) are mounted so as to be movable in the vertical direction on the movable support (510), thereby stably fixing and supporting the nutrient solution supply pipe (530) while allowing the nutrient solution supply position to be adjusted.

[0046] The nutrient supply pipe (530) is formed in a continuous curved 'L' shape and can be inserted into a plurality of pipe covers (520). In this way, the nutrient supply pipe (530) is formed so that the position where the nutrient is supplied can be adjusted according to the installation height of the cultivation module (400). As shown in FIG. 5-(a), the nutrient supply pipe (530) is installed in close contact, and as shown in FIG. 5-(b), the nutrient supply pipe (530) opens up and moves to the position of the cultivation module (400).

[0047] As shown in FIG. 2, the pipe connection nozzle (540) is configured to be connected to the nutrient supply pipe (530) and the cultivation module (400). The height of the pipe connection nozzle (540) can be changed as the nutrient supply pipe (530) extends vertically according to the movement of the shelf portion (200). This pipe connection nozzle (540) is connected so that the cultivation module (400) can be freely installed, and is configured to supply the nutrient solution at any position.

[0048] The nutrient solution dispenser (550) can be provided within the installation box (120) and supplies water and nutrient solution from the water tank (560) to allow the crop to grow. Additionally, the water tank (560) can be provided within the installation box (120) and is equipped to supply to the crop. The nutrient solution dispenser (550) and the water tank (560) can be equipped so that the nutrient solution and water are mixed and used, and can be equipped so that an automatic nutrient solution supply function is implemented to supply to the cultivation module (400) by spraying the roots 1 to 2 times at 1-hour intervals, and this time and number of sprays can be changed depending on the crop.

[0049] Referring to FIG. 2, the lighting unit (600) is configured to provide light so that the crop target (1) can grow. This lighting unit (600) is installed at the bottom of the shelf (210) and is positioned at the top of the cultivation module (400) so that light is irradiated onto the crop target (1). This lighting unit (600) is installed to maintain a certain distance from the crop target (1), and is configured so that the lighting unit (600) can move upward as the crop target (1) grows and increases in size.

[0050] At this time, the lighting unit (600) can be moved upward together with the shelf (210) by the shelf moving unit (300), and the lighting unit (600) alone can be moved while the cultivation module (400) is fixed, or the cultivation module (400) can be moved together with the lighting unit (600). In addition, the lighting unit (600) is equipped to implement an automatic lighting control function so that the lighting unit (600) is always positioned 1 to 4 cm above the top of the crop target (1) to maintain an illumination level suitable for growth.

[0051] The sensor unit (700) is configured to measure the distance to the top of the crop target (1) planted in the cultivation module (400). As such, the sensor unit (700) is installed at the bottom of the shelf (210) and detects the distance to the crop target (1) located at the bottom. At this time, when the distance to the crop target (1) measured by the sensor unit (700) reaches a set distance, the smart farm causes the shelf (210) to move upward.

[0052] That is, the sensor unit (700) measures and provides the distance to the crop target (1) so that as the crop target (1) grows and increases in size, it comes into contact with the shelf (210) located above, thereby preventing the crop target (1) from being damaged or its growth from being restricted. Additionally, the sensor unit (700) can cause the shelf (210) equipped with the lighting unit (600) to move upward according to the detected growth height of the crop target (1).

[0053] FIG. 6 is another example of installation of a refrigerator farm using a refrigerator according to an embodiment of the present invention. FIG. 6-(a) to 6-(c) shows the shelf section (200) and the cultivation module (400) moving upward and widening as the crop target (1) grows. The refrigerator farm can be formed such that the shelf section (200) and the cultivation module (400) are integrally formed and can move upward along the movable support (510). Additionally, the refrigerator farm can be installed so that the cultivation module (400) can be selectively separated to cultivate crop targets (1) of various heights.

[0054] FIG. 7 is another example of installation of a refrigerator farm using a refrigerator according to an embodiment of the present invention. The refrigerator farm can be installed such that the shelf (210) on which the cultivation module (400) is placed is fixed, and the lighting unit (600) is movable. Unlike FIG. 6, the smart farm can be installed such that the shelf unit (200) and the cultivation module (400) are selectively separated to cultivate crop targets (1) of various heights.

[0055] As such, the refrigerator farm of the present invention can adjust the installation height of the cultivation module (400) according to the size of the crop target (1) so that the user can cultivate a variety of crops desired by the user, and automatically adjusts the height of the lighting unit (600) to maintain optimal illumination conditions, thereby enabling the cultivation of crop target (1) of the highest quality.

[0056] Those skilled in the art to which the present invention pertains will understand that the invention may be implemented in modified forms without departing from the essential nature of the invention. Therefore, the disclosed embodiments should be considered in an illustrative rather than a limiting sense. The scope of the invention is defined by the claims, not by the foregoing description, and all variations within the scope of the claims should be interpreted as being included in the invention.
