Referring to fig. 1 and 6 to 11, the present application provides an air conditioning module 1 including a supply duct 11, a return duct 12, a baffle 14, and an air conditioning case 15. The supply duct 11 has a supply opening communicating with the controlled environment. Referring to fig. 6, the return duct 12 includes a return port 121 and a dust discharge port 122 penetrating in the thickness direction of the duct wall. The dust exhaust port 122 is disposed adjacent to the return air port 121. The baffle 14 is rotatably connected to the inner wall of the return duct 12 and is located between the return air inlet 121 and the dust exhaust port 122. The air conditioning box 15 is connected at both ends to the air supply duct 11 and the air return duct 12, respectively. The air conditioning module 1 has a cooling mode and a dust removal mode. In the cooling mode, the damper 14 is rotated toward the side of the dust discharge opening 122 to cover the dust discharge opening 122, air enters the air conditioning case 15 through the return air opening 121, and the cooled air is discharged to the controlled environment through the supply air opening. In the dust removing mode, the baffle plate 14 rotates toward the side of the return air inlet 121 to cover the return air inlet 121, and air reversely enters the return air duct 12 to be cleaned through the air conditioning box 15 and is discharged through the dust discharge port 122 to clean dust in the return air duct 12.

The air conditioning module 1 that this application provided can purify air in the controlled environment, air conditioning temperature and humidity, and can be through the mode of operation that changes air conditioning module 1 alright clean return air duct 12 to the dust of absorption in the clean return air duct 12 reduces the peculiar smell in the air current that is blown out by supply air duct 11. And the reverse airflow is utilized for cleaning, and a cleaning device is not required to be additionally arranged, so that the structure is simple and convenient, and the cost is reduced.

As shown in fig. 11, in some embodiments, the air conditioning module 1 further comprises a filter screen 16. The filter screen 16 is provided on the return air opening 121. In particular, filter screen 16 may prevent dust within the controlled environment from being drawn into return duct 12. Filter screen 16 is removable for periodic cleaning.

Specifically, the blower of the air conditioning compartment 15 may be rotated in forward and reverse directions, and may also be capable of processing the passing air flow to change the humidity and temperature of the air flow. In the cooling mode, the blower of the air conditioning box 15 rotates forward to generate negative pressure in the return duct 12, and the air in the controlled environment enters the return duct along the return opening 121 and is processed by the air conditioning box 15, and then is blown to the controlled environment through the air supply opening. In the dust removal mode, the fan of the air conditioning cabinet 15 is reversed to generate negative pressure in the air supply pipeline 11, and air enters the air supply pipeline 11 through the air supply opening and then reversely flows through the dust exhaust opening 122 in the return air pipeline 12 to be blown out, so that dust and impurities adsorbed on the inner wall of the return air pipeline 12 are removed, and peculiar smell is reduced. In addition, the baffle 14 can automatically cover the air return opening 121 in the dust removal mode, so that dust is prevented from passing through the air return opening 121 and polluting the filter screen 16 on the air return opening 121.

As shown in fig. 11, in some embodiments, the damper 14 is rotated toward the return air opening 121 side by the reverse air flow in the dust removing mode. In the dust removal mode, the fan of the air conditioning box 15 is rotated reversely, the baffle 14 automatically covers the air return opening 121 under the action of the airflow, manual control of rotation of the baffle 14 is not needed, and the operation is simple and convenient. The baffle 14 is made of a corrosion resistant lightweight material and has a structural strength and rigidity to facilitate frequent rotation and increase service life.

Referring to fig. 5, in some embodiments, the air conditioning module 1 further includes a spring 13. One end of the baffle 14 is rotatably connected with the inner wall of the return air duct 12, and the other end of the baffle 14 is connected with the inner wall of the return air duct 12 through a spring 13. In the cooling mode, the elastic force of the spring 13 causes the baffle plate 14 to cover the dust discharge port 122.

To increase the sealing of the baffle 14 to the air return opening 121 and the dust exhaust opening 122 and to facilitate the flow of air to exert a force on the baffle 14, in some embodiments, the baffle 14 includes a protrusion. In the cooling mode, the baffle plate 14 covers the dust discharge opening 122 and the projection is sunk into the dust discharge opening 122 by the elastic force of the spring 13. In the dust removal mode, the reverse airflow makes the baffle 14 overcome the elastic force of the spring 13 and rotate to the other side to cover the air return opening 121, and the convex part covers the outer side of the air return opening. With particular reference to fig. 4, the front view of the baffle 14 is shown as convex on one side and concave on the other side, since the baffle 14 has a convex portion. That is, a portion of the baffle 14 is curved. When the air conditioning box 15 rotates forward, as shown in fig. 8, the convex part of the baffle plate 14 sinks into the dust discharge opening 122 and the forward flowing air flow generates an acting force on the concave surface of the baffle plate 14, and the vertical downward component of the acting force cooperates with the elastic force of the spring 13 to further press the baffle plate 14 on the dust discharge opening 122, so that the shielding effect of the baffle plate 14 on the dust discharge opening 122 is increased. When the air conditioning case 15 is reversed, the reverse airflow first acts on the convex surface of the blocking plate 14 not caught in the dust discharge port 122 to rotate the blocking plate 14 against the force of the spring 13 to the state shown in fig. 11, and then the reverse airflow continues to exert force on the convex surface of the blocking plate 14 to keep the return air port 121 covered tightly. When the air conditioning box 15 stops reversing, the baffle plate 14 resets to the state shown in fig. 8 again under the action of the spring 13, the whole process is automatic, the air return opening 121 and the dust exhaust opening 122 can be well covered, the air return opening 121 is prevented from being polluted by dust in the pipeline, and the situation that the residual dust in the dust exhaust opening 122 is sucked again by negative pressure in the air return pipeline 12 when the air conditioning module 1 is in a refrigeration mode can also be avoided. Further, the dust exhaust port 122 is well sealed, which also improves the air tightness in the return duct 12, thereby improving the suction capacity of the return air inlet 121 and preventing the space airflow from entering the return duct 12 through the dust exhaust port 122.

Referring to fig. 2 and 3, in some embodiments, the baffle 14 includes a cover plate 141 and a bezel 142. The frame 142 is disposed around the cover plate 141. The frame 142 is made of a hard material. The cover plate 141 is made of a soft material. In particular, the use of a hard material (e.g., an aluminum alloy) for the frame 142 may improve the overall structural strength of the baffle 14, increasing the service life. The cover plate 141 can be in close contact with the air return opening 121 and the dust exhaust opening 122 by using a soft material (e.g., rubber), so that the covering performance is improved.

In some embodiments, the baffle 14 further comprises a gasket. Gaskets are provided on the rim 142 to further increase the covering properties of the baffle 14.

The air conditioning module 1 includes a plurality of baffles 14. The plurality of baffles 14 are correspondingly arranged between the plurality of air return openings 121 and the plurality of dust exhaust openings 122. Setting the number of the return air openings 121 and the dust discharge openings 122 to a plurality can improve the air supply efficiency and the dust removal effect.

In some embodiments, the air conditioning module 1 further comprises an air gauge. The anemometer is used to detect the wind speed in the return duct 12. Further, the air conditioning module 1 further comprises a controller, and the controller is in signal connection with the air gauge and the air conditioning box 15. The controller controls the rotation speed of the air conditioning box 15 based on the wind speed data detected by the anemometer to ensure that the wind speed in the return duct 12 can overcome the force of the spring 13 to drive the baffle plate 14 to rotate. The controller is also able to prevent blowing damage to the duct walls by controlling the rotational speed of the air-conditioning box 15 so that the wind speed is lower than a set value.

The controller is in signal connection with the pressure detection device and is used for controlling the on-off of the on-off valves 5, the working modes of the air conditioning modules 1 and the on-off of the pressure relief ports 17. Specifically, the pressure relief port 17 may be an electronic control valve, a valve core opening of the electronic control valve is controlled by a signal of a controller, and when the pressure in the return air duct 12 is too high, the controller sends a signal to make the valve core opening of the electronic control valve increase to implement pressure relief.
