The invention disclosed herein relates generally to growing plants using hydroponic gardening apparatuses. More particularly, the invention relates to a hydroponic gardening apparatus, which is portable, capable of growing plants with minimal human interaction, and capable of interfacing with horticulture tracking software.
Hydroponics refers to the method of growing plants without soil. Instead, the plants are grown using aerated stones and fed with mineral nutrient solutions. Conventional hydroponics systems used for indoor or industrial gardening applications require skilled labor for installation. Additionally, these systems lack portability thereby reducing their utility in applications requiring frequent movement of the hydroponic gardening equipment. A hydroponic gardening apparatus, which is portable and installed with minimum effort, is required. Furthermore, existing hydroponic systems do not provide feedback to a user in the event of a component malfunctioning. Alternately, a user cannot monitor fluid levels, temperature levels, and other ambient condition levels of the hydroponic system remotely via a communications network, for example, the internet. Conventional systems, therefore, lack a ‘smart’ or ‘intelligent’ notification and monitoring feature, which enables users to grow plants using hydroponics. An apparatus, which monitors ambient condition levels for optimal growth of the plants and notifies users of a malfunction or reduction in ambient condition levels, is required.
Additionally, it is common knowledge that growing plants require different nutrients at different stages of growth. The supply of chilled water also affects the growth of the plants grown in a hydroponic apparatus. If the roots of the plant are kept highly oxygenated and slightly chilled via a nutrient solution and air temperatures are kept slightly warm, plant growth is affected positively. An apparatus, which supplies chilled nutrient-rich fluids to a plant, is required. Moreover, in climates having hot and highly humid conditions, the humidity levels have to be reduced for providing an environment conducive to optimal plant growth. For applications like these, an apparatus, which is capable of dehumidifying the air surrounding the plant growing area, is required.
Hence, there is a long felt but unresolved need for an apparatus, which monitors ambient condition levels for optimal growth of the plants and notifies users of a malfunction or reduction in ambient condition levels. Furthermore, there is a need for an apparatus, which supplies chilled nutrient-rich fluids to a plant. Moreover, there is a need for an apparatus, which is capable of dehumidifying the air surrounding the plant growing area. Additionally, there is a need for an apparatus that can interface with horticulture tracking software and records events in real time via the internet.
This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.
The invention disclosed herein addresses the above-mentioned need for an apparatus, which monitors ambient condition levels for optimal growth of the plants and notifies users of a malfunction or reduction in ambient condition levels. Furthermore, the invention disclosed herein addresses a need for an apparatus, which supplies chilled nutrient-rich fluids to a plant. Moreover, the invention addresses a need for an apparatus, which is capable of dehumidifying the air surrounding the plant growing area. Additionally, the invention addresses a need for an apparatus that can interface with horticulture tracking software and records events in real time via the internet. The industrial hydroponic control apparatus for monitoring and modifying an environment for growing plants comprises a portable table, a reservoir, a refrigerator assembly, and a control device. The portable table comprises a plurality of predetermined positions for mounting a plurality of insulated plant containers. Each insulated plant container supports one or more plants. The reservoir is positioned below the portable table. The reservoir is in fluid communication with each insulated plant container to distribute a fluid to each insulated plant container and drain the excess fluid from each insulated plant container via a piping network. The refrigerator assembly is positioned adjacent to the reservoir. Furthermore, the refrigerator assembly is operably engaged to the reservoir. The refrigerator assembly adjusts a temperature of the fluid within a predefined range, thereby chilling the fluid. In an embodiment, the refrigerator assembly comprises a dehumidifier for dehumidifying the air surrounding the plants. The control device is in operable communication with the insulated plant containers, the refrigerator, and the reservoir. The control device is configured to monitor and modify the environment for growing the plants.
The foregoing summary, as well as the following detailed description of the invention, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, exemplary constructions of the invention are shown in the drawings. However, the invention is not limited to the specific methods and structures disclosed herein. The description of a method step or a structure referenced by a numeral in a drawing is applicable to the description of that method step or structure shown by that same numeral in any subsequent drawing herein.
In an embodiment, the reservoir 102 is positioned below the portable table 101. The reservoir 102 is in fluid communication with each insulated plant container 105 to distribute a fluid to each insulated plant container 105 and drain the excess fluid from each insulated plant container 105 via a piping network 110 exemplarily illustrated in
In an embodiment, the control device 104 is in operable communication with the pump and multiple sensors 125. The sensors 125, for example, flow sensors, temperature sensors, etc., are positioned on the refrigerator assembly 103 and the reservoir 102 for generating a plurality of sensor data variables. The control device 104 receives the generated sensor data variables from the sensors 125. A graphical user interface of the control device 104 displays the received sensor data variables and transmits the sensor data variables to either a server 127 or a monitoring device 126 via a communication network 128, as exemplarily illustrated in
The expansion device 113 is in fluid communication with the condenser 112 and receives the cooled working medium liquid. The expansion device 113 then further lowers the pressure of the cooled working medium liquid, thereby cooling the working medium to lower temperatures. The evaporator 114 is in fluid communication with the expansion device 113 and receives the low temperature-working medium. In an embodiment, the evaporator 114 comprises multiple coiled tubing 114a through which the highly cooled working medium is passed. This increases the surface area of contact available for external warm air from the condenser 112. Since the condenser 112 is positioned in front of the evaporator 114, the external warm air surrounding the condenser 112 is cooled when the air is exposed to the coiled tubing 114a of the evaporator 114. A fan or blower is provided to increase the rate of heat transfer between the external air and the working medium. Additionally, the fluid from the reservoir 102 is also brought into contact with a few of the coiled tubing 114a of the evaporator 114. The cooled working medium exchanges heat with the fluid in the reservoir 102, thereby chilling the fluid. In an embodiment, the refrigerator assembly 103 comprises a dehumidifier for dehumidifying the air surrounding the plants. The control device in operable communication with the insulated plant containers, the refrigerator, and the reservoir, the control device is configured for monitoring and modifying the environment for growing the plants.
The fluid fills the insulated plant container 105 from the bottom panel 105d. In an embodiment, the bottom panel is positioned at a height of about 2 inches from the bottom of the insulated plant container 105. The bottom panel 105d further comprises a drain port 105f which drains the fluid into a drain tube 105e and back to the piping network 110 via the outlet hose end 105c. In an embodiment, the insulated plant containers 105 are of a generally cylindrical configuration. The insulated plant containers 105 are formed using injection molding. Each insulated plant container 105 comes out of the mold looking very much like a typical four gallon, round, black plastic bucket. The insulated plant container 105 holds about three gallons of hydroponic medium. The insulated plant container 105 is formed with a two-inch skirt at the bottom as exemplarily illustrated in
In an embodiment, the outlet hose end 105c is a female ½-inch NPT (National Pipe Threads) recessed into the side of the bottom panel 105d. The recessed threads allow for the fitting to be removed so that the insulated plant containers 105 can be stacked for shipping or storage. In addition, the threaded fitting is necessary for cleaning, or theoretically to clear a clog in the line. The plumbing system is designed with a choke point at the ports, meaning any debris small enough to get thru the port will flush out the other end of the assembled line. The inlet hose end 105b and the outlet hose end 105c are vertically aligned with each other on the right hand side of the insulated plant container 105 as exemplarily illustrated in
The keeper ring secures a bug barrier fabric (weed block) laid over the top of the growing medium firmly against the inside of the insulated plant container 105. The keeper ring also prevents gnats and root aphids from getting into the grow stones. Once bugs enter the growing medium, it is virtually impossible to eradicate them and they can devastate a crop. A breathable fabric will not restrict air from getting to the roots when the hydro solution is not flowing. It is sliced from one side to the center allowing for easy installation and it will expand with the stalk as it grows. The screen 105h is made of an oval shaped piece of ¼″ galvanized steel mesh material. The screen 105h prevents the grow stones from getting out of the insulated plant container 105 and into the plumbing lines. The screen 105h is simply wedged into the mouth of either the inlet hose end 105b, the drain port 105f or the outlet hose end 105c, which allows the interior of the insulated plant container 105 to remain completely smooth and easy to clean. Other screens require retainer formations that are very difficult to clean and makes storage difficult for the insulated plant containers 105.
The screen 105h is easy to install by simply inserting it into the mouth of the drain port 105f. The screen 105h keeps the mouth of the drain port 105f clear of debris, the right angle of the drain port 105f prevents the screen 105h from being stuck in the line, and the choke point actually makes it easier for the pump to fill the insulated plant containers 105. In an embodiment, Teflon® tape of the CHEMOURS COMPANY FC, LLC is used on all threaded fittings to form a watertight seal.
In an embodiment, the supply and return piping are two separate trunk lines and are injection molded using black plastic. In an embodiment, the piping are assembled using ¾ inch, 200 PSI, PVC (for the return) and ¾ inch CPVC (for the supply). The trunk lines are factory assembled and then installed on site. They are installed lengthwise down the center of the table and clamped to (Unistrut) stand-offs that are mounted perpendicular to the top of the platform. The stand-offs are also tall enough to attach more pipes if necessary. Both trunk lines will have a clean out fitting at each end. The trunk lines are assembled using a combination of tees and 90 degree slip fittings that are glued together. These fittings are aimed horizontally toward the edge of the table and are appropriately aligned with each container position. These fittings are used to glue in hose whips that are specific to the supply and return fittings on each insulated plant container 105. These hose whips are cut to length and are connected directly to their corresponding fittings on each insulated plant container 105. They are made of a semi-flexible, ½ inch, black hose and each hose whip is equipped with a Female Hose End. The female hose ends contain a typical rubber O-ring for a watertight seal. The hose connectors make it very easy to connect and disconnect the insulated plant containers 105.
In an embodiment, the supply line is installed first, and is clamped to the stand-offs down as low as it can go, or about ¼″ above the platform. The supply line must be lower in elevation than the supply fitting on the insulated plant container 105 to allow the solution in the insulated plant container 105 to completely drain back into the reservoir 102 when the pump is shut off. Foam plumbing pipe insulation is provided to completely insulate the supply and return lines after they are installed. In an embodiment, the return trunk line is clamped to the same stand offs, elevating it approximately 2″ above the supply line allowing room for the foam insulation. To maintain an even flow rate, the return trunk line will tee in the middle of the system where it extends towards the left hand side of the table and takes compound angles (over and down) toward the oval shaped opening above the reservoir 102 as exemplarily illustrated in
The touchscreen interface of the control device 104 is used to enter data required for tracking, and for programming the refrigerator assembly 102, the circulation pump, and the de-humidifier. Once programmed, the settings are latched, meaning they remain during power loss. The control device 104 is also equipped with a small battery backup so that the time clock will keep time while the industrial hydroponic control apparatus 100 is unplugged. The control device 104 includes a digital thermometer and relative humidity display. Moreover, the control device 104 has status lights and warning lights that supervise the industrial hydroponic control apparatus 100. There are five reset buttons as well, one for GFCI protection and one for each of the four motors. They protect each motor individually, which will prevent the industrial hydroponic control apparatus 100 from shutting down due to a problem with one motor. If any sensor 125 trips, the status light changes from green to red on the control device 104 and a notification message appears on the monitoring device 105 if the monitoring device 104 is connected to the industrial hydroponic control apparatus 100 via the internet. Additionally, if the solution fails to flow during the pre-programmed period, an alarm is triggered to notify the operator.
The Built-In float switch ensures automatic re-filling of the reservoir 102. The float switch is also a low water sensor for the control device 104 of the industrial hydroponic control apparatus 100. If the float switch does not reach high level during top-off, a trouble notice will be triggered. The float switch is primarily designed to open and close the circuit to an electric (sprinkler) valve. The float switch leads are spliced to a two-wire cord with a Bi-Pin cord end on it. The cord end is necessary to maintain the portability of the industrial hydroponic control apparatus 100. The bi-pin cord plugs into the bi pin adapter 115 outlet. The bi pin adapter 115 is installed on the output side of any electric sprinkler valve where it is convenient to wire and operate. Furthermore, the bi pin adapter 115 is capable of being installed on any standard ¾″ pipe.
In an embodiment, the multiple interfaces 116 connect the sensors 125 to the control device 104. The multiple interfaces 112 are, for example, one or more bus interfaces, a wireless interface, etc. The network interface 123 connects the control device 104 to the communication network 128.
