[0027] Such as Figures 1-3As shown in the figure, a temperature control device for hydroponic cultivation according to an embodiment of the first aspect of the present invention includes a cabin body 100, a plurality of hydroponic rack bodies 200, a blowing temperature control component 300, and a return air structure. A long strip-shaped chamber 110 is provided inside the cabin body 100. The hydroponic rack bodies 200 are arranged inside the cabin body 100 and along the length direction of the chamber 110. The blowing temperature control component 300 includes a temperature control air outlet 310 and a temperature control air inlet 320. The blowing temperature control component 300 is arranged inside the cabin body 100 and the blowing temperature control component 300 is located at the head end of the chamber 110. The temperature control air outlet 310 blows air towards the tail end of the chamber 110. The return air structure is arranged along the length direction in the cabin body 100. A return air duct 331 is arranged inside the return air structure. The return air structure is provided with an air suction port 332 communicated with the head end of the return air duct 331 and an air supply port 333 communicated with the tail end of the return air duct 331. The air suction port 332 is located at the tail end of the chamber 110. The air supply port 333 is docked with the temperature control air inlet 320.

[0028] Among them, the cabin body 100 can be formed by splicing containers or sheet metal parts. The cabin body 100 can be in the shape of a cuboid, a long strip-shaped tank, or other irregular long strip shapes. The hydroponic rack bodies 200 can also be in the shape of long strips. Specifically, it can be formed by splicing horizontal support rods and vertical support rods to form a bracket, and then arranging multiple layers of plates arranged in upper and lower layers on the bracket. At least one hydroponic tank is arranged on each layer of plate, and fruit and vegetable plants can be planted in the hydroponic tank.

[0029] Specifically, the return air structure can enclose the return air duct 331 by using pipe fittings, or can also enclose the return air duct 331 by using the plate parts of the cabin body 100.

[0030] For the temperature control device for hydroponic cultivation of the present invention, the hydroponic rack bodies 200 are arranged along the length direction of the chamber 110, while the blowing temperature control component 300 is located at the head end of the chamber 110. The air flow output from the temperature control air outlet 310 is from the head end of the chamber 110 towards the tail end of the chamber 110. The air suction port 332 of the return air structure extends to the tail end of the chamber 110, providing suction at the tail end of the chamber 110, sucking the air flow into the return air duct 331 from the air suction port 332. The air flow returns to the air supply port 333, enters the blowing temperature control component 300 from the temperature control air inlet 320 for temperature control and then is output from the temperature control air outlet 310. Thus, the air flow continuously flows in the chamber 110, forming a cycle, which can make the temperature at each position in the chamber 110 uniform. The layout cost and operation cost of this design are reasonable, and it can effectively achieve uniform temperature control in different areas of the cabin.

[0031] In some embodiments of the present invention, the air suction port 332 is located at the bottom of the tail end of the chamber 110, and the temperature control air outlet 310 is located at the top of the head end of the chamber 110.

[0032] Generally speaking, the temperature-adjusting air outlet 310 of the air blowing and temperature-adjusting component 300 outputs cold air. The cold air moves towards the tail end of the chamber 110 and sinks during this process. Finally, it enters the return pipeline from the air extraction port 332 at the bottom of the tail end of the chamber 110, so that the air flow can flow to more positions within the chamber 110 to ensure uniform temperature.

[0033] Since the air extraction port 332 is located at the bottom of the tail end of the chamber 110, and the temperature-adjusting air outlet 310 is located at the top of the head end of the chamber 110, in some embodiments of the present invention, such as Figure 1 shown, the return air structure includes a return air duct member 330. The return air duct 331 is arranged within the return air duct member 330. The air extraction port 332 is opened at the head end of the return air duct member 330, and the air supply port 333 is opened at the tail end of the return air duct member 330. The return air duct member 330 has a bending portion 334 so that the return air duct member 330 extends from the top of the head end of the chamber 110 to the bottom of the tail end of the chamber 110.

[0034] The return air duct member 330 can be arranged close to the inner wall surface of the chamber 110. At the splicing position of adjacent wall surfaces, the return air duct member 330 can be transitioned through the bending portion 334, so that the return air duct member 330 can transition along one wall surface to extend along another wall surface.

[0035] In some embodiments of the present invention, the air blowing and temperature-adjusting component 300 includes a first housing, a first fan, and a temperature-adjusting module (not shown in the figure). The first housing is arranged within the cabin 100. A heat exchange air duct is arranged within the first housing. The temperature-adjusting air outlet 310 and the temperature-adjusting air inlet 320 are arranged on the first housing and are both communicated with the heat exchange air duct. The first fan is arranged within the first housing to guide the air flow to flow from the temperature-adjusting air inlet 320 to the temperature-adjusting air outlet 310. The temperature-adjusting module is arranged within the first housing to adjust the temperature of the air flow.

[0036] Under the agitation of the first fan, the air flow enters the first housing from the temperature-adjusting air inlet 320, and after being temperature-adjusted by the temperature-adjusting module, it is sent out from the temperature-adjusting air outlet 310. Specifically, the temperature-adjusting module includes one or more of a semiconductor refrigeration sheet and a compression refrigeration component.

[0037] In some embodiments of the present invention, such as Figure 2 、 3As shown, the temperature control device for hydroponic cultivation further includes a fresh air component 400 and an air exchange duct component 500. An air exchange duct is provided in the air exchange duct component 500. The air exchange duct component 500 is provided with a fresh air inlet 550 communicating with the head end of the air exchange duct and a fresh air outlet 560 communicating with the tail end of the air exchange duct. The fresh air component 400 communicates with the fresh air inlet 550, the fresh air outlet 560, and the outside respectively. The air exchange duct component 500 is provided with a plurality of fresh air outlets 510 and a plurality of exhaust outlets 520 that are all communicated with the air exchange duct along the length direction.

[0038] The fresh air component 400 communicates with the outside of the cabin 100. The fresh air component 400 can send fresh air from the outside into the air exchange duct component 500. The fresh air flows into the chamber 110 at the fresh air outlet 510. The air in the chamber 110 can enter the air exchange duct component 500 at the exhaust outlet 520 and then be discharged to the outside through the fresh air component 400.

[0039] In some embodiments of the present invention, as Figure 2 shown, the fresh air component 400 is provided at the tail end of the cabin 100. The air exchange duct component 500 is arranged along the length direction of the chamber 110. A plurality of fresh air outlets 510 and a plurality of exhaust outlets 520 are both arranged along the length direction of the air exchange duct component 500. Thus, the air in each area in the length direction of the cabin 100 has corresponding fresh air outlets 510 and exhaust outlets 520 for ventilation, ensuring that the air in most areas inside the cabin 100 is fresh.

[0040] In some embodiments of the present invention, as Figure 2 shown, the air exchange duct component 500 includes an air outlet pipe section 530 and an air inlet pipe section 540 arranged side by side with each other. The fresh air inlet 550 is provided at the head end of the air outlet pipe section 530. The fresh air outlet 560 is provided at the tail end of the air inlet pipe section 530. A plurality of the fresh air outlets 510 are arranged on the air outlet pipe section 530 along the length direction of the air outlet pipe section 530. A plurality of the exhaust outlets 520 are arranged on the air inlet pipe section 540 along the length direction of the air inlet pipe section 540. The fresh air outlets 510 and the exhaust outlets 520 are offset from each other in the length direction.

[0041] The air exchange duct member 500 has an air outlet duct section 530 and an air inlet duct section 540 arranged side by side and independent of each other. Fresh air can enter the air outlet duct section 530 from the fresh air inlet 550. The air flow flows into the chamber 110 through each fresh air outlet 510 arranged along the length direction of the air outlet duct section 530, while the air in the chamber 110 can enter the air inlet duct section 540 at each air outlet 520 arranged along the length direction of the air inlet duct section 540 and is finally discharged. The fresh air and the air in the chamber 110 are not easily interfered and mixed with each other in the air exchange duct member 500. The misaligned fresh air outlets 510 and air outlets 520 enable the fresh air output from the fresh air outlets 510 not to be immediately discharged from the air outlets 520, and the fresh air can flow towards the chamber 110.

[0042] In some embodiments of the present utility model, as Figure 2 shown, the hydroponic rack body 200 has at least two rows. The two rows of hydroponic rack bodies 200 are arranged side by side and there is an interval space between the two rows of hydroponic rack bodies 200. The air exchange duct member 500 is located in the interval space.

[0043] The air exchange duct member 500 is arranged in the interval space. The hydroponic rack body 200 is not likely to block the air outlet and air inlet of the fresh air outlet 510 and the air outlet 520 on the air exchange duct member 500, and at the same time, it can also take into account the air usage requirements of the plants on the hydroponic rack body 200.

[0044] In some embodiments of the present utility model, the fresh air assembly 400 includes a second housing and a second fan. The second housing penetrates through the cabin body 100. The second housing is provided with a first air exchange opening 410 and a second air exchange opening 420 that are isolated from each other. The two ends of the second housing are respectively connected to the air exchange duct member 500 so that the fresh air inlet 550 is communicated with the first air exchange opening 410 and the fresh air outlet 560 is communicated with the second air exchange opening 420. The second fan is arranged in the second housing to guide the air flow to enter the air exchange duct from the first air exchange opening 410 and flow out from the second air exchange opening 420.

[0045] Specifically, there can be two second fans. One second fan is used to extract external air and send it to the air outlet duct section 530, and the other second fan is used to extract the air in the chamber 110 to the air inlet duct section 540 and discharge it to the outside.

[0046] Specifically, filter meshes 430 can be arranged at both the first air exchange opening 410 and the second air exchange opening 420 to reduce the entry of external dust into the chamber 110.

[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0048] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
