CONTAINER UNIT AND CONTAINER ASSEMBLY FOR HYDROPONICS

Abstract

A container unit for hydroponics includes a container having an overflow unit and an outflow unit located therein. The overflow unit includes an overflow tube, and the outflow unit includes a siphon pipe which is height adjustable. A cover is mounted to the container and includes an opening, a first hole and a second hole. A pot is engaged with the opening of the cover. Two hooks are connected to the back of the container so as to be hooked to a shelve to form multiple rows of the containers between which the overflow tubes and the outflow tubes are connected via the first and second holes of the containers. The overflow tube and siphon pipe control the water level in the container to prevent plant root from being rotted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] Referring to FIGS. 1 to 4, the container unit “A” for hydroponics of the present invention comprises a container 1 having an overflow unit 2 and an outflow unit 3 located therein. The overflow unit 2 includes an overflow tube 21, and the outflow unit 3 includes a siphon pipe 31 which is height adjustable. The outflow unit 3 includes an outlet 10 formed through the underside of the container 1. The siphon pipe 31 is a U-shaped pipe and includes a U-section 310 which has an oval cross section. The siphon pipe 31 includes an inlet 311 formed in the first end thereof. The second end of the siphon pipe 31 is inserted into the outlet 10. Multiple seal rings 312 are located between the outlet 10 and the second end of the siphon pipe 31.

[0027] A cover 4 is mounted to the container 1 and has an opening 41, a first hole 42 and a second hole 43. A pot 5 is engaged with the opening 41 of the cover 4. At least one hook 6 is connected to the back of the container 1. The container 1 includes a reception part 11 on at least one side thereof. A light part 7 is inserted into the reception part 11 and includes a clip 71 so as to secure a light tube 84 as shown in FIG. 5. The overflow tube 21 and siphon pipe 31 control water level in the container 1 to prevent plant root from being rotted.

[0028] The top face of each of the containers 1 is inclined downward 37 degrees relative to a horizontal plane so that the plant in the pot is tilt and grows toward light. A concaved and curved face 12 is formed to a front face of the container 1.

[0029] As shown in FIGS. 3, 5 and 5a, a container assembly “B” for hydroponics is disclosed and comprises a shelve 8 including a frame 82 which is connected to a water tank 81. The frame 82 includes multiple transverse bars 821. A feeding tube 83 has one end thereof connected with a motor 80 in the water tank 81 so as to pump nutrient solution or liquid from the water tank 81 to the containers “A”.

[0030] The multiple containers 1 are hooked to the transverse bars 821 by the at least one hook 6 of each container 1 so as to form at least two rows of containers 1 along the transverse bars 821. The feeding tube 83 includes multiple dripping tubes 831 which are respectively inserted into the second holes 43 of the containers 1 of the first row or the top row of the containers 1. The overflow tubes 21 of the containers 1 of the first row of the containers 1 are inserted into the first holes 42 of the containers 1 of the second row of the containers 1. The second row of the containers “A” are located below the first row of the containers “A”. The outflow tube 13 is connected to the outlet 10 of each of the containers 1 of the first row of the containers 1, and the outflow tubes 13 of the first row of the containers 1 are inserted into the second holes 43 of the containers 1 of the second row of the containers 1. The outlet 10 of each container 1 of the second row of the containers 1 face the water tank 81. The shelve 8 may have multiple rows of the containers “A” which are interconnected by the overflow tubes 21 and the outflow tubes 13.

[0031] The nutrient liquid are provided to the containers “A” via the dripping pipes 831 connected to the feeding tube 83. When the water level of the nutrient liquid in the containers “A” reaches the top of the siphon tube 13, the siphon tube 13 is operated so that the nutrient liquid in the containers “A” flows downward to the containers “A” of the lower row of the containers “A”. When the water level of the upper row of the containers “A” is lowered and below the inlet 311 of the siphon tube 31, the siphon tube 31 sucks air to stop the nutrient liquid from flowing out. The nutrient liquid eventually drops into the water tank 81 from the lowest row of the containers “A”. The water level of the nutrient liquid in each container “A” is lowered regularly to let the plant roots to such the nutrients and air. The nutrient liquid circulates to provide nutrient to the plant, while the plant roots are protected from being rotted.

[0032] The siphon tube 31 can be adjusted according to different needs of different plants, and the seal rings 312 ensure the sealing feature so that the water level can be precisely controlled.

[0033] It is noted that the U-section 310 of the siphon tube 31 has an oval cross section. When the nutrient liquid reaches the U-section 310, the water level in the siphon tube 31 increases quickly and the nutrient liquid together with the air in the siphon tube 31 flow toward the second end of the siphon tube 31. Therefore, the siphon effect is effective and only limited nutrient liquid is required.

[0034] When a foreign object is sucked in the siphon tube 31 and the siphon tube 31 fails to normally operate, the water level is increased in the container “A” and will flows to the lower row of the containers “A” via the overflow tube 21.

[0035] The container assembly “B” include multiple rows of the containers “A” and arranged from upper position to lower position, so that the nutrient liquid can flows downward from the first row to the last (the lowest) row of the containers “A”. This saves the nutrient liquid required and also saves the electricity required for the motor 80.

[0036] As shown in FIGS. 5 and 5a, the light parts 7 are easily positioned to the containers “A” by the reception parts 11, and the light tubes 84 are secured to the light parts 7 which provide light to the plants in the pots 5 when desired in any season.

[0037] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
