In addition, the specific air quantity entering the jet air duct 10 can be controlled by adjusting the rotating speed of the jet fan 20, and the air quantity is not influenced by other external factors and is accurately and stably controlled.
In particular, the fluidic device 1 further comprises at least one additional functional module 30, each additional functional module 30 being selectively in communication with the outlet plenum 11 through a damper to selectively apply a corresponding additional function to the airflow entering the outlet plenum 11 or exiting through the outlet plenum 11.

In some embodiments, the jet duct 10 includes an outlet duct 13 extending vertically and an inlet duct 14 extending horizontally outward from the bottom of the outlet duct 13. The air outlet cavity 11 is formed in the air outlet duct 13, and the air outlet cavity 11 can be a vertically extending strip-shaped air outlet cavity. The heat exchange airflow outlet is usually located at the front side of the cabinet air conditioner indoor unit so as to supply air towards the front side. Therefore, the jet outlet 12 may be formed on the front side 131 of the outlet duct 13 so as to be mixed with the heat exchange air flowing out from the heat exchange air outlet. The jet fan 20 is arranged at the intersection of the air outlet duct 13 and the air inlet duct 14, so that the size of the jet device 1 in the transverse direction or the front-back direction is not increased, the jet device 1 is more suitable for being integrated in a cabinet air-conditioning indoor unit with higher vertical height and smaller size in other directions, and the cabinet air-conditioning indoor unit is prevented from being large in size or complex in structure.

That is, the second electrically controlled damper 52 can be controlled to connect the fluid communication between the air outlet duct 80 and the air outlet chamber 11, or to block the fluid communication between the air outlet duct 80 and the air outlet chamber 11. Therefore, when the additional function module 30 in a certain air outlet pipeline 80 needs to be started, the second electric control air door 52 in the air outlet pipeline 80 can be controlled, so that the air outlet pipeline 80 is communicated with the air outlet cavity 11, part of air flow in the air outlet cavity 11 flows to the air outlet pipeline 80 and flows to the indoor space after flowing through the additional function module 30 in the air outlet pipeline 80, and the additional function module 30 is utilized to apply corresponding additional functions to the air flow flowing through the additional function module.
Fig. 2 and 3 are schematic structural views of a fluidic device according to a second embodiment of the present invention in different states, and the dotted arrows in fig. 3 indicate the flow direction of the air stream. In some embodiments, the fluidic device 1 further comprises at least one additional functional chamber 60 attached alongside the fluidic air duct 10. Each additional function chamber 60 is provided with a corresponding additional function module 30, and a third electrically controlled damper 53 is arranged between each additional function chamber 60 and the air outlet cavity 11, wherein the third electrically controlled damper 53 is configured to controllably position the additional function module 30 in the additional function chamber 60 on the airflow path from the jet flow fan 20 to the jet flow outlet 12, so as to apply a corresponding additional function to the airflow flowing to the jet flow outlet 12 through the additional function module 30.
Specifically, the third electrically controlled damper 53 is in a closed state, see fig. 2, the additional function chamber 60 is isolated from the outlet chamber 11, and the airflow in the outlet chamber 11 does not flow to the additional function chamber 60. In the open state of the third electrically controlled damper 53, see fig. 3, the outlet air chamber 11 is blocked and divided into a first section communicating with the jet outlet 12 and a second section communicating with the jet fan 20, the first and second sections communicating through the additional function chamber 60. Therefore, the airflow driven by the jet fan 20 flows to the additional function chamber 60 through the second section, flows to the first section after flowing through the additional function module 30 in the additional function chamber 60, and is further sent out from the jet air outlet 12, and the airflow sent out from the jet air outlet 12 carries the additional functions applied by the additional function module 30, such as humidification, aromatherapy, purification, and the like.
Fig. 4 is a schematic structural view of a fluidic device according to a third embodiment of the present invention. In some embodiments, the jet device 1 has an indoor air inlet 141 communicated with the indoor space where it is located, and specifically, the indoor air inlet 141 may be opened at an end of the air inlet duct 14 far from the air outlet channel 13. At least one air inlet duct 70 is connected in parallel to the indoor air inlet 141, and each air inlet duct 70 is open to an indoor space where the jet device 1 is located. That is, each air intake duct 70 communicates with the indoor space where the jet device 1 is located.
Further, a corresponding additional function module 30 is disposed in each air inlet duct 70, and a fourth electrically controlled damper 54 is disposed between each air inlet duct 70 and the air inlet duct 14 between the indoor air inlet 141 and the jet flow fan 20, the fourth electrically controlled damper 54 being configured to controllably communicate the air inlet duct 70 and the air inlet duct 14, so that the indoor air flows through the air inlet duct 70 to the jet flow fan 20, and thus the corresponding additional function module 30 in the air inlet duct 70 applies a corresponding additional function to the air flowing to the jet flow fan 20. Therefore, when the additional function module 30 in a certain air inlet pipeline 70 needs to be started, the fourth electrically controlled damper 54 in the air inlet pipeline 70 can be controlled, so that the air inlet pipeline 70 is communicated with the air inlet duct 14, the air flow in the indoor space flows to the air outlet duct 13 through the air inlet pipeline 70 and flows to the indoor space through the jet air outlet 12, and the additional function module 30 is utilized to apply corresponding additional functions to the air flow flowing through the additional function module.
Specifically, when the fourth electrically controlled damper 54 is in the closed state, the fluid connection between the air inlet line 70 and the air inlet duct 14 is blocked, and the air flow driven by the jet fan 20 flows through the air inlet duct 14 to the air outlet duct 13. When the fourth electrically controlled damper 54 is in the open state (in fig. 4, the fourth electrically controlled damper 54 is in the open state), the fluid connection between the air inlet pipeline 70 and the air inlet duct 14 is opened, and the air flow driven by the jet fan 20 flows at least partially through the air inlet pipeline 70 to the air outlet duct 13. It should be noted that the fourth electrically controlled damper 54 may block the air inlet duct 14 when in the open state, at this time, the airflow driven by the jet fan 20 flows to the air outlet duct 13 completely through the air inlet pipeline 70, and the air inlet duct 14 may not be blocked when the fourth electrically controlled damper 54 is in the open state.
As can be seen from the above embodiments, since the additional function module 30 is selectively communicated with the air outlet cavity 11 through the air door, the additional function module 30 may be disposed in the air inlet pipe 70 for introducing the air flow into the air outlet cavity 11, may also be disposed in the air outlet pipe 80 for introducing the air flow in the air outlet cavity 11, and may also be disposed on the air flow path between the jet flow fan 20 and the jet flow outlet 12, so as to improve the flexibility of the position arrangement of the additional function module 30.
In some embodiments, the at least one additional function module 30 may include one or more of a humidification module, a purification module, and an aromatherapy module. In other embodiments, the additional function module 30 may also include modules capable of performing other additional functions on the airflow.
In some embodiments, the fluidic device 1 can include one or more of the outlet duct 80, the inlet duct 70, and the additional function chamber 60. When the number of the additional function modules 30 is plural, the plural additional function modules 30 may be disposed at different positions according to actual situations. For example, when the fluidic device 1 includes three additional function modules 30, the three additional function modules 30 may be respectively disposed in the three outlet ducts 80, respectively disposed in the three inlet ducts 70, respectively disposed in the three additional function chambers 60, respectively disposed in one outlet duct 80, one inlet duct 70, and one additional function chamber 60, respectively disposed in two outlet ducts 80 and one inlet duct 70, and so on.
