Detailed Description

In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

Firstly, to facilitate understanding, returning to the description of the background section, the hydroponic apparatus in the prior art has problems of large volume, being unsuitable for being placed in a living room, large fluctuation of liquid level, unstable flow rate, and the like.

In view of at least one of the above technical problems, or other possible technical problems, an exemplary embodiment of the present utility model provides a tray assembly for a household hydroponic apparatus, wherein the tray assembly includes: a tray body configured with an inflow port and an outflow port and a flow passage communicating the inflow port and the outflow port for a nutrient solution to flow therethrough; and a tray cover plate covering the tray main body and configured with a plurality of receiving holes for receiving the seed plants, wherein the flow path is curvedly configured, and a buffer portion is provided at least one turn portion of the flow path.

By the configuration of the tray assembly according to the utility model, the dimensions of the household hydroponic apparatus can be made smaller, in particular substantially corresponding to the conventional dimensions of the household appliance, thanks to the meandering configuration of the flow channel, and thus suitable for being placed in the living room. In addition, the buffer part is arranged at the bending part of the runner, so that the liquid level of the nutrient solution can not be severely fluctuated due to abrupt trend change of the runner, thereby providing stable flow rate of the nutrient solution and ensuring the silent growth environment required by plant root systems.

For a better understanding of the present utility model, exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

A system block diagram of a household hydroponic apparatus 100 according to one embodiment of the utility model is shown in schematic diagram in fig. 1. As shown in fig. 1, the household hydroponic apparatus 100 includes a tray assembly 1, a reservoir 2 for a nutrient solution, and a circulation pump 3. The household hydroponic apparatus 100 employs, for example, a so-called NFT cycle (Nutrient Film Technique) that intermittently supplies nutrient solution to the tray assembly 1, causing the nutrient solution to flow through the planted seed plants and back to the reservoir 2, and so on, cycling through the cycle, achieving nutrient and oxygen supply to the plants. Here, the circulation pump 3 is arranged to be adapted to pump nutrient solution into the flow channel 13 of the tray assembly 1. The user can change and/or replenish the nutrient solution in the reservoir 2.

According to a preferred embodiment, not shown, the household hydroponic apparatus 100 according to the utility model comprises a plurality of tray assemblies 1. Preferably, the plurality of tray assemblies 1 are connected to each other in series, thereby enabling nutrient solution to flow into the flow channels of the respective tray assemblies 1 in sequence. Further preferably, a plurality of tray assemblies are stacked one above the other. In this case, the nutrient solution is pumped by means of the circulation pump 3 to the uppermost tray assembly, and then flows into the respective tray assemblies below in sequence by its own weight. However, it is alternatively also conceivable for a plurality of pallet assemblies 1 to be connected in parallel with one another and/or to be arranged alongside one another, as desired.

In fig. 2, a perspective view of a tray assembly 1 for a household hydroponic apparatus 100 according to one embodiment of the utility model is shown in a schematic view, wherein the tray assembly 1 is in an assembled state.

An exploded view of the tray assembly 1 for the household hydroponic apparatus 100 of fig. 1 according to one embodiment of the utility model is schematically illustrated in fig. 3.

As can be seen from fig. 2 and 3, the tray assembly 1 includes a tray main body 10 and a tray cover 20. Here, in the assembled state, the tray cover 20 covers the tray main body 10. The tray cover 20 is provided with a plurality of receiving openings 21 for receiving the seed plants, which are preferably arranged uniformly distributed on the tray cover 20, for example, the receiving openings being arranged at the same distance from the tray cover 20. However, it is alternatively also conceivable for a different number of a plurality of receiving openings 21 to be arranged on the tray cover 20 in any desired arrangement, in particular in a manner suitable for receiving the planted seed plants. According to a preferred embodiment, the outer surface of the tray cover 20 is configured to reflect light, particularly through an electroplating process. Therefore, strong light of the plant light supplementing lamp can be reflected, the strong light is prevented from shining on nutrient solution in the flow channel of the planting tray, and the breeding of green algae is reduced.

In fig. 4, a tray body 10 of a tray assembly 1 for a household hydroponic apparatus according to one embodiment of the utility model is shown in a top view. As can be seen from fig. 3 and 4, the tray body 10 is configured with an inflow port 11 and an outflow port 12, and a flow passage 13 is arranged between the inflow port 11 and the outflow port 12. According to the utility model, the nutrient solution can be pumped into the inflow 11, through the flow channel 13 and out of the outflow 12 to the reservoir 2 by means of the circulation pump 3. Furthermore, an inlet baffle 111 is configured at the inflow 11 and an outlet baffle 121 is configured at the outflow 12. Here, the level of the nutrient solution in the tray body 10, which is preferably 30mm in height, is maintained by these baffles 111 and 121. According to the utility model, the root systems of the individual plants can be immersed through the individual receiving openings 21 into the nutrient solution in the flow channel 13, which nutrient solution is enriched with the nutrient substances used for cultivating the individual plants.

Meanwhile, an inlet baffle 111 is constructed at the inflow port 11 and an outlet baffle 121 is constructed at the outflow port 12, it is possible to ensure that an air layer exists between the tray cover 20 and the liquid surface of the nutrient solution for supplying oxygen, through which root anoxic growth can be avoided. The air layer thickness is preferably 20mm.

Further, by means of the inlet baffle 111, the flushing speed of the nutrient solution at the time of opening the water circulation can be reduced, and further the fluctuation of the liquid level can be reduced, thereby helping to maintain a gentle flow rate of the nutrient solution.

According to a preferred embodiment, a filter screen 30 may be arranged at the outflow opening 12, said filter screen being arranged to be suitable for filtering impurities in the nutrient solution, such as detached stubbles, green algae, etc. In particular, in the case of a plurality of tray assemblies 1 connected in series, in particular one above the other, the filter screen 30 in each tray assembly 1 can advantageously prevent impurities, such as detached root systems, green algae, etc., from flowing into the circulation line connecting the tray assemblies 1, so that said impurities prevent nutrient solution circulation.

In fig. 5, an enlarged detail view of the tray body 10 at the outflow opening 12 is shown. As can be seen from fig. 5, an overflow recess 1211 is formed in the outlet baffle 121. Thus, the influence of the water surface tension on the flow velocity can be reduced, and the outflow of the nutrient solution can be accelerated in an overflow manner, so that the circulation efficiency of the nutrient solution can be improved.

As can also be seen from fig. 3 and 4, the flow channel 13 is of meandering design, i.e. of multi-fold design. By means of such a meandering configuration, the dimensions of the tray assembly 1 in the longitudinal direction can be reduced with the same effective length of the flow channel 13, so that the dimensions of the tray assembly 1 or of the corresponding household hydroponic apparatus 100 are adapted to conventional household appliances, in particular so that the household hydroponic apparatus 100 can resemble the morphological configuration of a household appliance, for example a refrigerator. As shown in fig. 3 and 4, the flow channel 13 is divided into a plurality of sub-flow channels parallel to one another, for example, by a plurality of bends, for example, four sub-flow channels being provided. However, it is alternatively also conceivable that the flow channel 13 is divided into any number of sub-flow channels, or that the sub-flow channels are arranged non-parallel to each other, as long as they are shaped or dimensioned to accommodate the planted plants and to be placed in the living room.

According to a preferred embodiment, ventilation grooves 40 are provided between the individual sub-channels of the flow channel 13, said ventilation grooves being arranged to allow air to circulate between the individual sub-channels. As shown in fig. 3, the ventilation grooves 40 are, for example, formed as depressions, in particular as a plurality of depressions distributed uniformly, on the dividing wall separating the individual sub-channels. Preferably, the ventilation groove 40 is integrally formed with the tray body 10. Fresh air can thus pass through these ventilation grooves 40 across the various sub-channels to fully contact the liquid surface, allowing the plant root system to obtain sufficient oxygen.

As can also be seen from fig. 3 and 4, a temperature sensor 50 is arranged in the tray assembly 1. The temperature sensor 50 is arranged, for example, at a bend between the second and third sub-flow channels. The temperature of the nutrient solution in the tray assembly 1 can be detected by the temperature sensor 50, so that the temperature suitable for planting plants can be adjusted accordingly.

According to a preferred embodiment, at least one buffer 131, 132 is provided in the flow channel 13 of the tray assembly 1. Optionally, the buffer parts 131, 132 are integrally formed at least one corner of the flow channel 13 of the tray body 10. Alternatively, it is also conceivable for the buffer parts 131, 132 to be constructed as separate components from the tray body 10, for example as components which can be detachably or replaceably mounted between the individual sub-channels, in order to flexibly adapt to different application requirements, for example for different plants, for achieving different flow rates, etc. Preferably, the buffer 131, 132 has a buffer angle α, β between 140 ° and 155 °. Alternatively, only one buffer portion may be provided, for example, at the corner of the sub-flow path to which the inflow port 11 is connected, thereby moderating the flow rate of the nutrient solution injected from the inflow port 11. Alternatively, a plurality of buffer portions 131, 132 may be provided, and buffer angles α, β of the respective buffer portions may be set to be the same as or different from each other. An exemplary embodiment according to the present utility model is shown in fig. 4. For example, a first buffer 131 is provided between the first and second sub-flow channels and between the third and fourth sub-flow channels, the buffer angle α of which is in particular 153.4 °. For example, a second buffer 132 is provided between the second and third sub-channels (adjacent to the temperature sensor 50), the buffer angle β of which is in particular 146.6 °. Such buffer portions 131, 132 having the buffer angles α, β are provided for reducing the liquid vortex at the turning, whereby the fluctuation of the liquid level of the nutrient solution flowing in the flow path 13 can be reduced, particularly, the fluctuation of the liquid level is controlled within 1 mm.

Further, by means of the buffer parts 131, 132 in combination with the pumping rate of the circulation pump 3, the liquid level speed at the turn can be controlled to be 0.015 m/s.+ -. 0.005m/s, whereby the surge impact to which the plant root system is subjected can be reduced. Also, since the tray body 10 is generally manufactured by injection molding, setting the buffer angles α, β between 140 ° and 155 ° is also advantageous for demolding of the tray body 10.
