In particular, appropriate heating facilities are essential to maintain crop growth in low-temperature winter environments. However, conventional greenhouse heating methods primarily rely on convection heating to heat the entire air, which presents problems such as high energy consumption and high costs. Since this approach focuses on uniformly heating the entire greenhouse rather than providing localized heating to specific areas, it suffers from significant heat loss and economic inefficiency. The problem to be solved

[0006] In exemplary embodiments, the carbon heating mesh is electrically connected to a power supply unit that provides energy to generate heat.

[0007] In exemplary embodiments, the frame comprises at least one selected from polyethylene, polypropylene, polyvinyl chloride, polystyrene, polycarbonate, polyamide, acrylonitrile butadiene styrene, polylactic acid, polyethylene terephthalate, polyoxymethylene, ethylene-vinyl acetate, and polysulfone.

[0010] In exemplary embodiments, the density of the first to fourth meshes decreases as they move away from the base plate within the first to fourth cavities. Effects of the invention

[0011] According to exemplary embodiments, a heating device for cultivation may include a base plate having a lower cavity, first and second side walls extending vertically from both sides of the base plate to define a receiving space and each having first and second cavities inside, and a frame including third and fourth side walls extending between the first and second side walls on the base plate and each having third and fourth cavities inside, and a lower mesh having a plurality of lower voids provided within the lower cavity, and a carbon heating mesh having first to fourth meshes provided within the first to fourth cavities.

[0012] Accordingly, the cultivation heating device can provide a structurally stable and efficient heating system through the frame composed of the base plate having the lower cavity, the first and second side walls surrounding the base plate (110), and the third and fourth side walls.

The carbon heating mesh enables rapid and uniform heat release and has excellent durability, allowing for stable heating performance over a long period.

[0013] In addition, the first to fourth meshes, each disposed within the first to fourth cavities, can further enhance the stability of the cultivation heating device (10) while simultaneously distributing heat. The design combining the lower cavity and the first to fourth cavities with the lower mesh and the first to fourth meshes allows for precise temperature adjustment in specific sections, thereby optimizing the growth environment of crops. This enables a significant reduction in energy consumption compared to conventional convection heating methods and allows for the implementation of an environmentally friendly heating method. These characteristics can reduce maintenance costs for the heating equipment and improve user convenience.

[0022] FIG. 1 is a perspective view showing a cultivation heating device having a carbon heating mesh according to exemplary embodiments. FIG. 2 is a cross-sectional view taken along line A-A' of FIG. 1. FIG. 3 is a cross-sectional view taken along line B-B' of FIG. 1. FIG. 4 is a cross-sectional view taken along line C-C' of FIG. 1.

[0023] Referring to FIGS. 1 to 4, a heating device for cultivation (10) comprises a base plate (110) having a lower cavity (112), first and second side walls (120, 130) extending vertically from both sides of the base plate (110) and including first and second cavities (122, 132), and third and fourth side walls (140, 150) extending between the first and second side walls (120, 130) and having third and fourth cavities (142, 152), a frame (100), a lower mesh (210) having a plurality of lower voids (216) within the lower cavity (112), and first to fourth meshes (220, 230) respectively provided within the first to fourth cavities (122, 132, 142, 152). It may include a carbon heating mesh (200) having 240, 250).

[0024] In exemplary embodiments, the cultivation heating device (10) can enable uniform and efficient heat distribution through the stability of the frame (100) and the cavity structure. The cultivation heating device (10) can optimize heat distribution by adjusting the mesh density and can be designed to maintain the crop growth environment in an energy-efficient manner by enhancing durability and performance through a variety of material choices.

[0025] In exemplary embodiments, the frame (100) may include a base plate (110), first and second side walls (120, 130) provided on both sides of the base plate (110), and third and fourth side walls (140, 150) extending between the first and second side walls (120, 130).

[0026] The base plate (110) may have a lower cavity (112). The lower cavity (112) may accommodate a heat transfer medium or a heating mesh to maximize heating efficiency.

[0027] The base plate (110) may include a plurality of placement areas (PR) suitable for plant placement on the upper surface and a plurality of surrounding areas (SR) each surrounding the plurality of placement areas (PR). The placement areas (PR) are spaces where crops are directly placed, and can provide an environment optimized for crop growth. The surrounding areas (SR) are spaces that surround the placement areas (PR) as boundaries, and can ensure the stability and uniformity of heat transfer and strengthen structural strength. The placement areas (PR) and the surrounding areas (SR) are separated from each other to regulate temperature distribution and together design the cultivation environment in detail.

[0028] Plants (PL) can be placed on top of multiple placement areas (PR). The multiple placement areas (PR) are designed to efficiently transfer heat to the body or root portion of the plants (PL), thereby providing conditions for stable growth even in low-temperature winter environments. The multiple placement areas (PR) can be designed to distribute the heat uniformly and induce the plants (PL) to have uniform growth conditions. The multiple placement areas (PR) can improve agricultural productivity and create an energy-efficient cultivation environment.

[0029] First and second side walls (120, 130) may be provided on the base plate (110). The first and second side walls (120, 130) may extend in a vertical direction (Z direction) from both sides of the base plate (110). The first and second side walls (120, 130) may define a receiving space (AS) on the first and second side walls (120, 130). Third and fourth side walls (140, 150) may be provided on the base plate (110). The third and fourth side walls (140, 150) may extend between the first and second side walls (120, 130) on the base plate (110). The third and fourth side walls (140, 150) together with the first and second side walls (120, 130) can define a receiving space (AS) on the base plate (110).

[0030] The first to fourth side walls (120, 130, 140, 150) can provide a waterproof function capable of storing water (W) on the base plate (110). Since the first to fourth side walls (120, 130, 140, 150) provide the waterproof function, the cultivation heating device (10) can hydroponically cultivate the plant by storing water (W) in the receiving space (AS).

[0031] The first and second side walls (120, 130) may each have first and second cavities (122, 132). The first and second cavities (122, 132) may extend along the first and second side walls (120, 130). The first and second cavities (122, 132) may provide space for accommodating the first and second meshes (220, 230) of the carbon heating mesh (200). The third and fourth side walls (140, 150) may each have third and fourth cavities (142, 152). The third and fourth cavities (142, 152) may extend along the third and fourth side walls (140, 150). The third and fourth cavities (142, 152) may provide space for accommodating the third and fourth meshes (240, 250) of the carbon heating mesh (200). The lower cavity (112) and the first to fourth cavities (122, 132, 142, 152) may be connected to each other. Alternatively, the lower cavity (112) and the first to fourth cavities (122, 132, 142, 152) may be provided within the base plate (110) and the first to fourth side walls (120, 130, 140, 150), respectively, so as to be disconnected from each other.

[0032] In this specification, the direction (X direction) between the first side wall (120) and the second side wall (130) is referred to as the first horizontal direction, the direction (Y direction) between the third side wall (140) and the fourth side wall (150) is referred to as the second horizontal direction, and the direction perpendicular to the first horizontal direction and the second horizontal direction is referred to as the vertical direction (Z direction).

[0033] The base plate (110) and the first to fourth side walls (120, 130, 140, 150) may comprise the same material. For example, the base plate (110) and the first to fourth side walls (120, 130, 140, 150) may comprise a metallic material such as stainless steel (Fe). Alternatively, the base plate (110) and the first to fourth side walls (120, 130, 140, 150) may comprise a plastic material.

[0034] The frame (100) may include the plastic material or the metal material having high hardness and high toughness. The frame (100) can protect the plants (PL) contained in the receiving space (AS) from external impact when the plants (PL) are contained in the receiving space (AS). When the plants (PL) are not contained, the frame (100) can be stored and managed individually, and since it has a rectangular structure, multiple frames can be stored in a stacked state.

[0035] The frame (100) can efficiently transfer the heat to plants (PL) contained in the receiving space (AS) through the metal material or the plastic material. For example, the frame (100) may include carbon materials with high heat transfer efficiency, and through the carbon materials, the heat generated from the carbon heating mesh (200) can be uniformly distributed along the frame (100) and transferred to the water (W). The frame (100) can optimize the growth environment of crops by stably and continuously supplying the heat required for the plant bulbs and roots within the receiving space (AS).

[0036] For example, the frame (100) may include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), nylon (PA), acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), polyethylene terephthalate (PET), polyoxymethylene (POM), ethylene vinyl acetate (EVA), polysulfone (PSU), etc.

[0037] In exemplary embodiments, the carbon heating mesh (200) may include a lower mesh (210) provided within a lower cavity (112), and first to fourth meshes (220, 230, 240, 250) respectively provided within first to fourth cavities (122, 132, 142, 152). The carbon heating mesh (200) may be provided inside the frame (100).

[0038] The lower mesh (210) and the first to fourth meshes (220, 230, 240, 250) may have a mesh structure. The lower mesh (210) and the first to fourth meshes (220, 230, 240, 250) may be designed so that the heat can be generated and dispersed uniformly inside the frame (100) through the mesh structure. The carbon heating mesh (200) is electrically connected to an external power supply and can continuously maintain heat by converting electrical energy supplied from the external power supply into thermal energy.

[0039] The lower mesh (210) may include a plurality of first extension structures (212) and a plurality of second extension structures (214). The plurality of first extension structures (212) may extend in a first horizontal direction (X direction) within the lower cavity (112), and the plurality of second extension structures (214) may extend in a second horizontal direction (Y direction) within the lower cavity (112).

[0040] The lower mesh (210) may include a plurality of lower voids (216) formed by a plurality of first extension structures (212) and a plurality of second extension structures (214). The plurality of lower voids (216) may be formed by extending each of the plurality of first extension structures (212) and the plurality of second extension structures (214) so ​​as to intersect each other.

[0041] The size or area of ​​the lower voids (216) can be varied according to the arrangement of the first extension structures (212) and the second extension structures (214), and such structural variations can be optimized according to the type and characteristics of the plants being cultivated. For example, heat transfer to the bulbs and roots of plants can be optimized by applying wider voids to the roots of large plants and finer voids to small plants. Through this, the lower mesh (210) can minimize heat loss and create a stable and uniform thermal environment for crop growth.

[0042] The first to fourth meshes (220, 230, 240, 250) may each be provided within the first to fourth cavities (122, 132, 142, 152) of the first to fourth side walls (120, 130, 140, 150). The first to fourth meshes (220, 230, 240, 250) together with the lower mesh (210) can control the temperature of the water (W) within the frame (100). When the lower mesh (210) applies heat from the bottom of the water (W) within the frame (100), the first to fourth meshes (220, 230, 240, 250) can apply heat from the sides of the water (W) within the frame (100). The first to fourth meshes (220, 230, 240, 250) together with the lower mesh (210) can rapidly raise the temperature of the water (W) inside the frame (100).

[0043] The first to fourth meshes (220, 230, 240, 250) may be provided to extend from the lower mesh (210). When the lower cavity (112) and the first to fourth cavities (122, 132, 142, 152) are connected to each other, the first to fourth meshes (220, 230, 240, 250) and the lower mesh (210) may be provided to extend to each other. Alternatively, the first to fourth meshes (220, 230, 240, 250) and the lower mesh (210) may be provided to be spaced apart from each other. When the lower cavity (112) and the first to fourth cavities (122, 132, 142, 152) are respectively provided within the base plate (110) and the first to fourth side walls (120, 130, 140, 150) and are provided so as to be separated from each other, the first to fourth meshes (220, 230, 240, 250) and the lower mesh (210) may be provided so as to be spaced apart from each other.

[0044] As illustrated in FIG. 2, the heat generated from the carbon heating mesh (200) can be transferred to the water (W) contained within the frame (100) through the lower mesh (210) and the first to fourth meshes (220, 230, 240, 250). In this process, the water (W) is efficiently heated through convection, forming a uniform temperature distribution across the entire receiving space (AS) within the frame (100). In particular, this heat transfer mechanism is designed to directly transfer heat to the roots or bulbs of plants (PL) via the water (W), thereby providing a thermal environment optimized for crop growth even in low-temperature winter environments. The carbon heating mesh (200) minimizes heat loss while maximizing energy efficiency and can provide stable and continuous heating in greenhouses or cultivation environments.

[0045] The carbon heating mesh (200) may have excellent durability and high thermal conductivity. The carbon heating mesh (200) can operate stably throughout the entire lifespan of the cultivation heating device (10). The density or arrangement method of the mesh structure can be adjusted to further improve heat distribution and transfer efficiency, thereby maximizing the performance of the cultivation heating device (10). The carbon heating mesh (200) can create an energy-efficient growth environment for crops and improve cultivation productivity.

[0046] The carbon heating mesh (200) may include a high thermal conductivity material to efficiently transfer the heat. The carbon heating mesh (200) may be composed of a composite material containing a metal component, and such a material can rapidly and uniformly disperse the generated heat based on its high thermal conductivity. The carbon heating mesh (200) may be designed so that the heat is not concentrated in a specific area but is evenly transferred to the water (W) from the lower cavity (112) and the first to fourth cavities (122, 132, 142, 152) within the frame. Through this, the heat generated from the carbon heating mesh (200) effectively heats the water (W) within the frame (100) and promotes convection of the water (W), thereby continuously and stably transferring heat to the roots or bulbs of the crop.

[0047] For example, the carbon heating mesh (200) may include nickel (Ni), antimony (Sb), bismuth (Bi), zinc (Zn), indium (In), palladium (Pd), platinum (Pt), aluminum (Al), copper (Cu), molybdenum (Mo), titanium (Ti), gold (Au), silver (Ag), chromium (Cr), tin (Sn), etc.

[0048] As described above, the cultivation heating device (10) can provide a structurally stable and efficient heating system through a frame (100) composed of a base plate (110) having a lower cavity (112), first and second side walls (120, 130) surrounding the base plate, and third and fourth side walls (140, 150). By forming a multi-layer structure through a lower mesh (210) and first to fourth meshes (220, 230, 240, 250) respectively provided within the lower cavity (112) and the first to fourth cavities (122, 132, 142, 152), heat can be uniformly distributed and effectively transferred to a specific area. By concentrating heat transfer to the area where it is needed through the lower mesh (210), energy loss can be minimized and efficient heat distribution can be achieved. The carbon heating mesh (200) enables fast and uniform heat release and has excellent durability, allowing it to provide stable heating performance for a long period of time.

[0049] In addition, the first to fourth meshes (220, 230, 240, 250) respectively disposed within the first to fourth cavities (122, 132, 142, 152) can further enhance the stability of the cultivation heating device (10) while simultaneously distributing heat. The design combining the lower cavity (112), the first to fourth cavities (122, 132, 142, 152), the lower mesh (210), and the first to fourth meshes (220, 230, 240, 250) allows for fine adjustment of the temperature in specific sections, thereby optimizing the growth environment of crops. This enables a significant reduction in energy consumption compared to conventional convection heating methods and allows for the implementation of an environmentally friendly heating method. These characteristics can reduce maintenance costs for the heating equipment and improve user convenience.

[0050] FIG. 5 is a drawing showing the lower mesh of a cultivation heating device according to exemplary embodiments. FIG. 6 is a drawing showing the convection phenomenon generated by the lower mesh of FIG. 5. The cultivation heating device is substantially identical or similar to the cultivation heating device described with reference to FIG. 1 through 4, except for the configuration of the lower mesh. Accordingly, identical components are indicated by identical reference numerals, and repeated descriptions of identical components are omitted.

[0051] Referring to FIGS. 1 to 6, a heating device for cultivation (10) comprises a base plate (110) having a lower cavity (112), first and second side walls (120, 130) extending vertically from both sides of the base plate (110) and including first and second cavities (122, 132), and third and fourth side walls (140, 150) extending between the first and second side walls (120, 130) and having third and fourth cavities (142, 152), a frame (100), a lower mesh (210) having a plurality of lower voids (216) within the lower cavity (112), and first to fourth meshes (220, 230, 240) respectively provided within the first to fourth cavities (122, 132, 142, 152). It may include a carbon heating mesh (200) having 250).

[0052] The lower mesh (210) may include a plurality of first extension structures (212) and a plurality of second extension structures (214). The plurality of first extension structures (212) may extend in a first horizontal direction (X direction) within the lower cavity (112), and the plurality of second extension structures (214) may extend in a second horizontal direction (Y direction) within the lower cavity (112).

[0053] The lower mesh (210) may include a plurality of lower voids (216) formed by a plurality of first extension structures (212) and a plurality of second extension structures (214). The plurality of lower voids (216) may be formed by extending each of the plurality of first extension structures (212) and the plurality of second extension structures (214) so ​​as to intersect each other.

[0054] A plurality of lower voids (216) may each be provided on a plurality of placement areas (PR) and a plurality of surrounding areas (SR). A plurality of lower voids (216) may each have first areas (A1) on a plurality of placement areas (PR). A plurality of lower voids (216) may each have second areas (A2) on a plurality of surrounding areas (SR). Each of the second areas (A2) may be smaller than each of the first areas (A1).

[0055] Because the second areas (A2) of the plurality of surrounding areas (SR) are smaller than the first areas (A1) of the plurality of placement areas (PR), the method and distribution of heat transfer between the plurality of placement areas (PR) and the plurality of surrounding areas (SR) can be controlled through the difference in area. Since the lower voids (216) on the plurality of placement areas (PR) have wider first areas (A1), heat transfer on the plurality of placement areas (PR) can be reduced and convection can be promoted. When heat is transferred through convection compared to being transferred directly to the plant (PL), the heat distribution becomes more uniform and the overall growth environment of the crop can be optimized.

[0056] In a plurality of surrounding areas (SR), the lower voids (216) each have a second area (A2) that is narrower than the first area (A1), and the lower mesh (210) can be designed to be more densely packed in the surrounding areas (SR). This structure can cause the lower mesh (210) to generate more heat in the surrounding areas (SR), thereby inducing the heat to be evenly transferred to plants (PL) located in the placement areas (PR) through the convection phenomenon. The amount of heat generated in the surrounding areas (SR) can be increased, the heat transfer efficiency due to the convection phenomenon can be increased, and the thermal uniformity in the placement areas (PR) can be enhanced. Through this structure, the lower mesh (210) provides structural advantages that can reduce energy consumption and maximize heat transfer performance, and can create more stable and efficient growth conditions for crops.

[0057] FIG. 7 is a drawing showing the first to fourth meshes of a cultivation heating device according to exemplary embodiments. The cultivation heating device is substantially identical or similar to the cultivation heating device described with reference to FIG. 1 to 4, except for the configuration of the lower mesh. Accordingly, identical components are indicated by identical reference numerals, and repeated descriptions of identical components are omitted.

[0058] Referring to FIGS. 1 to 4 and FIG. 7, a heating device for cultivation (10) comprises a base plate (110) having a lower cavity (112), first and second side walls (120, 130) extending vertically from both sides of the base plate (110) and including first and second cavities (122, 132), and third and fourth side walls (140, 150) extending between the first and second side walls (120, 130) and having third and fourth cavities (142, 152), a frame (100), a lower mesh (210) having a plurality of lower voids (216) within the lower cavity (112), and first to fourth meshes (220) respectively provided within the first to fourth cavities (122, 132, 142, 152). It may include a carbon heating mesh (200) having 230, 240, 250).

[0059] In exemplary embodiments, the first to fourth meshes (220, 230, 240, 250) may each be provided within the first to fourth cavities (122, 132, 142, 152) of the first to fourth side walls (120, 130, 140, 150). The first to fourth meshes (220, 230, 240, 250) together with the lower mesh (210) can control the temperature of the water (W) within the frame (100). When the lower mesh (210) applies heat from the bottom of the water (W) within the frame (100), the first to fourth meshes (220, 230, 240, 250) may apply heat from the sides of the water (W) within the frame (100). The first to fourth meshes (220, 230, 240, 250) together with the lower mesh (210) can rapidly raise the temperature of the water (W) inside the frame (100).

[0060] The density of the first to fourth meshes (220, 230, 240, 250) may decrease as they move away from the base plate (110) within the first to fourth cavities (122, 132, 142, 152). The density of the first to fourth meshes (220, 230, 240, 250) may decrease as they move away from the base plate (110) in a vertical direction (Z direction). The first to fourth meshes (220, 230, 240, 250) together with the lower mesh (210) may increase the temperature of the water (W) within the frame (100). The first to fourth meshes (220, 230, 240, 250) together with the lower mesh (210) may cause the convection phenomenon in the water (W) within the frame (100).

[0061] Since the high-temperature fluid has a lower density than the low-temperature fluid, the above convection phenomenon can occur, and since the first to fourth meshes (220, 230, 240, 250) are formed to be denser as they get closer to the base plate (110), the heat can be applied to the lower part of the water (W) inside the frame (100) and the above convection phenomenon can occur effectively. Since the first to fourth meshes (220, 230, 240, 250) have a lower density as they get further away from the base plate (110), the cost incurred during the manufacturing process of the cultivation heating device (10) can be reduced.

[0062] FIG. 8 is a drawing showing patterns of a cultivation heating device according to exemplary embodiments. The cultivation heating device is substantially the same or similar to the cultivation heating device described with reference to FIG. 1 through 6, except for the configuration of the lower mesh. Accordingly, the same components are indicated by the same reference numerals, and the repeated description of the same components is omitted.

[0063] Referring to FIGS. 1 to 6 and FIG. 8, a heating device for cultivation (10) comprises a base plate (110) having a lower cavity (112), first and second side walls (120, 130) extending vertically from both sides of the base plate (110) and including first and second cavities (122, 132), and third and fourth side walls (140, 150) extending between the first and second side walls (120, 130) and having third and fourth cavities (142, 152), a frame (100), a lower mesh (210) having a plurality of lower voids (216) within the lower cavity (112), and first to fourth meshes (220) respectively provided within the first to fourth cavities (122, 132, 142, 152). It may include a carbon heating mesh (200) having 230, 240, 250).

[0064] In exemplary embodiments, the base plate (110) may include first patterns (400) and second patterns (410). The first patterns (400) and second patterns (410) may guide a user to a location where a plant (PL) can be placed within the frame (100). The first patterns (400) and second patterns (410) may guide the user to effectively place the plant (PL), thereby inducing heat to be evenly transferred to the plant (PL) through the convection phenomenon.

[0065] The first patterns (400) may be provided to protrude over the placement areas (PR). The first patterns (400) may be provided to be spaced apart from the lower mesh (210) by a first distance (D1). The first patterns (400) can reduce the heat directly transferred from the lower mesh (210) to the placement areas (PR) through the protruding structure.

[0066] The second patterns (410) may be provided on the surrounding areas (SR). The second patterns (410) may be provided so as to be spaced apart from the lower mesh (210) by a second distance (D2). The second distance (D2) may be smaller than the first distance (D1). Because the second distance (D2) of the second patterns (410) is smaller than the first distance (D1) of the first patterns (400), the heat directly transferred from the lower mesh (210) to the surrounding areas (SR) can be increased.

[0067] Through the first and second patterns (400, 410), the user can efficiently determine the location where the plant (PL) should be placed. The first patterns (400) can activate the convection phenomenon by reducing direct heat transfer to the plant (PL), and the heat can be transferred indirectly to the plant to form a uniform heat distribution. The first patterns (400) can prevent excessive heat from concentrating at the bottom of the plant (PL) and maintain a stable growth environment by minimizing temperature deviations.

[0068] The second patterns (410) can induce more heat to be generated on the surrounding areas (SR) and can induce the heat to be transferred to the placement areas (PR) through the convection phenomenon. The second patterns (410) can help maintain a uniform heat distribution on the placement areas (PR) by making the surrounding areas (SR) a source of the convection phenomenon. The difference between the first and second distances of the first and second patterns (400, 410) can maximize the effect of the convection phenomenon to increase the heat transfer efficiency and create a stable heating environment while saving energy.

[0069] The first and second patterns (400, 410) can be designed to finely adjust the heat distribution according to the location of the plants (PL). The placement areas (PR) where the first patterns (400) are located have a low need for the plants (PL) to receive heat directly, and the second patterns (410) in the surrounding areas (SR) can help generate more heat and transfer it to the placement areas (PR). The first and second patterns (400, 410) can provide an environment where the user can easily identify the optimal placement location and where the plants (PL) receive heat evenly and grow uniformly. The first and second patterns (400, 410) can serve as important components that simultaneously improve the heating efficiency of the cultivation system and the productivity of the crops.

That is, within the scope of the purpose of the present invention, all components may be selectively combined in one or more ways to operate.
