The container is a modular or container-type structure, and multiple sets of mushroom racks are installed inside the container. The mushroom racks are used to place one or more types of mushroom crops. The air conditioning system includes a fan, a heat exchanger, a compressor, a filter, a misting device, and ventilation ducts. The control system includes an intelligent control platform and various sensors. The air conditioning system is used to regulate and control the temperature, humidity, and airflow inside the mushroom house. The components include a volute (31), an impeller (32), and a shaft (33). The impeller is installed inside the volute and on the shaft, which is connected to a drive motor. An outlet pipe is provided on the volute, which is approximately tangent to the outer periphery of the volute. The volute has a front side plate (34), and an arc-shaped inlet ring (35) is provided at the center of the front side plate, extending into the volute. The impeller includes a front cover plate (321), a rear cover plate (322), and blades (323). Multiple blades are distributed circumferentially and connected to the front and rear cover plates. In a cross-sectional view through the same plane, there is a first radial gap G1 between the outer circumferential surface of the impeller and the inner circumferential surface of the volute, and a second radial gap G2 between the outer circumferential surface of the impeller and the inner circumferential surface of the volute. The first and second sides are arranged opposite each other at 180° or opposite each other about the rotating shaft (33). Gap G1 < Gap G2. The position of the first radial gap G1 is the first end A, and the position of the second radial gap G2 is the second end B. The second end B is located adjacent to / close to the outlet pipe. The feature is that: the front side plate (34) A flow guide (36) is provided on the outer side of the arc-shaped inlet ring. The flow guide is located radially outside the arc-shaped inlet ring and adjacent to the arc-shaped inlet ring. The flow guide includes a first flow guide (37), an annular protrusion (38), and a second flow guide (39). Multiple first flow guides are distributed circumferentially at 360° or in a circle. Multiple second flow guides are distributed circumferentially at Q1°, and 45° < Q1° < 180°. The second flow guide is formed on the annular protrusion by removing material. The first flow guide is disposed between the arc-shaped inlet ring and the annular protrusion.

[0006] Furthermore, 90° < Q1° < 150°.

[0007] Furthermore, the front side plate (34) is provided with one or more connecting holes (41), which are respectively connected to the channels between multiple first guide vanes (37), the channels between multiple second guide vanes (39), and the return channel between the front cover plate (321) and the front side plate. The angle between the axis of the connecting hole and the axis of the impeller 32 is 40-70°.

[0008] Furthermore, the first guide vane (37) has a cross-section of a right triangle, and the hypotenuse of the right triangle is approximately tangent to the arc surface of the arc-shaped inlet ring (35); the arc-shaped inlet ring extends from the upper side of the front side plate (34) into the volute, and the lower end of the arc-shaped inlet ring extends to below the lower side of the front cover plate (321).

[0009] Furthermore, the cross-section of the annular protrusion (38) is approximately a right-angled triangle, and the hypotenuse of the approximately right-angled triangle is part of a circular arc.

[0010] Furthermore, a third guide vane (40) is provided on the outer circumferential surface of the arc-shaped inlet ring (35). Multiple third guide vanes are distributed along the circumferential direction Q2°, and 45° < Q2° < 180°. The third guide vane is provided adjacent to the inner circumferential surface of the front cover plate. The axis of the connecting hole (41) passes through the gap channel between the third guide vane and the inner circumferential surface of the front cover plate (321).

[0011] Furthermore, 90° < Q2° < 150°.

[0012] Furthermore, the circumferential Q1° coverage area partially overlaps or completely repeats the circumferential Q2° coverage area.

[0013] Furthermore, in the top view, the rotation / tilt direction of the first guide vane (37) is opposite to that of the second guide vane (39) and the third guide vane (40), and the rotation / tilt direction of the second guide vane (39) and the third guide vane (40) are the same.

[0014] The present invention discloses a modular intelligent mushroom house and its air conditioning system and fan. The fan, through the design of the guide section and / or connecting hole, can adjust or improve the return flow rate / velocity at the second end of the return channel on the outer side of the front cover plate, and introduce the airflow on the outer side of the front plate into the return channel through the connecting hole; through multiple second guide vanes distributed along the circumferential direction Q1°, with 45° < Q1° < 180°, it can adjust or improve the inlet flow rate / velocity at the second end B of the arc-shaped inlet ring, thereby increasing the fan flow rate and ensuring flow stability, improving fan efficiency, and thus providing effective protection for constant temperature, constant humidity, and constant flow in the intelligent mushroom house.

[0015] This invention utilizes multiple third guide vanes distributed circumferentially at Q2°, with 45° < Q2° < 180°. The rotation / tilt direction of the first guide vane is opposite to that of the second and third guide vanes. This allows for better adjustment or improvement of the return flow rate / velocity at the second end of the return channel on the outer side of the front cover plate, and better adjustment or improvement of the inlet flow rate / velocity at the second end B of the arc-shaped inlet ring. This, in turn, increases the fan flow rate and ensures flow stability, thereby improving fan efficiency and providing effective protection for constant temperature, humidity, and flow rate in the intelligent mushroom house.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] like Figure 1-4As shown, a modular intelligent mushroom house includes a container 10, mushroom racks 20, an air conditioning system 30, and a control system. The container 10 is a modular / container-type three-dimensional structure. Multiple sets of mushroom racks 20 are installed inside the container 10. The mushroom racks 20 are used to place one or more types of mushrooms / fungi. The air conditioning system 30 includes a fan, a heat exchanger, a compressor, a filter, a misting device, and ventilation ducts. The control system includes an intelligent / smart control platform and various sensors (such as temperature sensors, humidity sensors, carbon dioxide / CO2 sensors, etc.). The air conditioning system 30 is used to regulate and control factors such as temperature, humidity, and airflow / ventilation rate inside the mushroom house.

[0025] The fan includes a casing / volute 31, an impeller 32, and a shaft 33. The impeller 32 is installed inside the volute 31 and on the shaft 33, which is connected to a drive motor. An outlet pipe is provided on the volute 31, approximately tangentially to the outer periphery of the volute 31 (as is known, not shown). The volute 31 has a front side plate 34, with an arc-shaped inlet ring 35 at its center, extending inwards into the volute 31. The impeller 32 includes a front cover plate 321, a rear cover plate 322, and blades 323. Multiple blades 323 are circumferentially distributed and connected between the front cover plate 321 and the rear cover plate 322. In a cross-sectional view through the same plane, a first radial gap G1 exists between the outer circumferential surface of the impeller 32 and the inner circumferential surface of the volute 31, and a second radial gap G2 exists between the outer circumferential surface of the impeller 32 and the inner circumferential surface of the volute 31, with the first and second sides being 180° apart. The device is configured relative to or about the rotating shaft 33, with gap G1 < gap G2. The first radial gap G1 is located at the first end A, and the second radial gap G2 is located at the second end B. The second end B is located adjacent to / close to the outlet pipe (as is known, not shown). The device is characterized by: a guide portion 36 is provided on the outer surface of the front side plate 34. The guide portion 36 is located radially outside and adjacent to the arc-shaped inlet ring 35. The guide portion 36 includes a first guide plate 37, an annular protrusion 38, and a second guide plate 39. Multiple first guide plates 37 are distributed circumferentially at 360°, and multiple second guide plates 39 are distributed circumferentially at Q1°, with 45° < Q1° < 180°, preferably 90° < Q1° < 150°. The second guide plates 39 are formed on the annular protrusion 38 by removing material. The first guide plates 37 are located between the arc-shaped inlet ring 35 and the annular protrusion 38.

[0026] Furthermore, one or more connecting holes 41 are provided on the front side plate 34. The connecting holes 41 are respectively connected to the channels between multiple first guide vanes 37, the channels between multiple second guide vanes 39, and the return channel between the front cover plate 321 and the front side plate 34. The angle between the axis of the connecting hole 41 and the axis of the impeller 32 is 45-65°.

[0027] The cross-section of the first guide vane 37 is a right triangle, and the hypotenuse of the right triangle is approximately tangent to the arc surface of the arc-shaped inlet ring 35. The arc-shaped inlet ring 35 extends from the upper side of the front side plate 34 into the volute 31, and the lower end face of the arc-shaped inlet ring 35 extends to below the lower side of the front cover plate 321.

[0028] The cross-section of the annular protrusion 38 is approximately a right-angled triangle, and the hypotenuse of the approximately right-angled triangle is part of a circular arc.

[0029] In the prior art, the pressure difference between the first end A and the second end B causes the flow rate / velocity of the backflow on the outer side of the front cover plate 321 to be different, and the flow rate / velocity of the first end A and the second end B corresponding to the arc-shaped inlet ring 35 to be different, which causes the flow rate of the fan to decrease or become unstable, and the fan efficiency to decrease.

[0030] This invention provides a modular intelligent mushroom house and its air conditioning system and fan, such as... Figure 2-4 As shown by the arrow, the airflow direction, through the design of the guide section 36 and / or the connecting hole 41, can adjust or improve the return flow rate / velocity of the second end B of the return channel on the outer side of the front cover plate 321, and introduce the airflow on the outer side of the front side plate 34 into the return channel through the connecting hole 41; through the multiple second guide vanes 39 distributed along the circumferential direction Q1°, and 45°<Q1°<180°, the inlet flow rate / velocity of the second end B of the arc-shaped inlet ring 35 can be adjusted or improved, thereby increasing the fan flow rate and ensuring flow stability, and improving the fan efficiency.

[0031] Furthermore, a third guide vane 40 is provided on the outer circumferential surface of the arc-shaped inlet ring 35. Multiple third guide vanes 40 are distributed along the circumferential direction Q2°, and 45° < Q2° < 180°. Preferably, 90° < Q2° < 150°. The third guide vane 40 is provided adjacent to the inner circumferential surface of the front cover plate 321. The axis of the connecting hole 41 passes through the gap channel between the third guide vane 40 and the inner circumferential surface of the front cover plate 321.

[0032] The circumferential Q1° coverage area partially overlaps or completely repeats the circumferential Q2° coverage area.

[0033] like Figure 4 As shown in the top view, the rotation / tilt direction of the first guide vane 37 is opposite to that of the second guide vane 39 and the third guide vane 40, and the rotation / tilt direction of the second guide vane 39 and the third guide vane 40 is the same.

[0034] The present invention uses multiple third guide vanes 40 distributed circumferentially at Q2°, where 45° < Q2° < 180°, preferably 90° < Q2° < 150°. The rotation / tilt direction of the first guide vane 37 is opposite to that of the second guide vane 39 and the third guide vane 40. This allows for better adjustment or improvement of the return flow rate / velocity at the second end B of the return channel on the outer side of the front cover plate 321, and better adjustment or improvement of the inlet flow rate / velocity at the second end B of the arc-shaped inlet ring 35. This improves the fan flow rate and ensures flow stability, thereby increasing the fan efficiency.

[0035] This invention discloses a modular intelligent mushroom house and its air conditioning system and fan. The fan, through the design of the guide section 36 and / or connecting hole 41, can adjust or improve the return flow rate / velocity at the second end B of the return channel on the outer side of the front cover plate 321, and introduce airflow from the outer side of the front side plate 34 into the return channel through the connecting hole 41. Multiple second guide vanes 39 are distributed circumferentially at Q1°, with 45° < Q1° < 180°. Preferably, 90° < Q1° < 150°, which can adjust or improve the inlet flow rate / velocity at the second end B of the arc-shaped inlet ring 35, thereby increasing the fan flow rate and ensuring flow stability, improving fan efficiency, and thus providing effective protection for constant temperature, constant humidity, and constant flow rate in the intelligent mushroom house.

[0036] This invention utilizes multiple third guide vanes 40 distributed circumferentially at Q2°, with 45° < Q2° < 180°, preferably 90° < Q2° < 150°. The rotation / tilt direction of the first guide vane 37 is opposite to that of the second guide vane 39 and the third guide vane 40. This allows for better adjustment or improvement of the return flow rate / velocity at the second end B of the return channel on the outer side of the front cover plate 321, and better adjustment or improvement of the inlet flow rate / velocity at the second end B of the arc-shaped inlet ring 35. This improves the fan flow rate and ensures flow stability, thereby increasing fan efficiency and providing effective protection for constant temperature, humidity, and flow rate in the intelligent mushroom house.

It is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
