From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:
in the air outlet mechanism provided by the invention, the air outlet mechanism comprises a through-flow channel 10, a flow distribution plate 30 and two air outlets 20, wherein the two air outlets 20 are both communicated with the through-flow channel 10 and are arranged at intervals along the circumferential direction of the through-flow channel 10; the flow distribution plate 30 is movably arranged in the through-flow channel 10 along the distribution direction of the two air outlets 20, and the flow distribution plate 30 has a shielding state and an avoiding state between the two air outlets 20; when the flow distribution plate 30 is in the shielding state, the flow distribution plate 30 is disposed opposite to one of the two outlets 20, so as to shield the outlet 20.
In a specific implementation process, the two air outlets 20 are respectively a first air outlet 21 and a second air outlet 22, and when the flow distribution plate 30 moves to a position between the first air outlet 21 and the second air outlet 22, the flow distribution plate 30 avoids both the first air outlet 21 and the second air outlet 22, that is, at this time, the flow distribution plate 30 does not shield the first air outlet 21 and the second air outlet 22, and the airflow in the through-flow channel 10 can flow out through the first air outlet 21 and the second air outlet 22; when the flow distribution plate 30 moves to a position opposite to the first air outlet 21, the flow distribution plate 30 is stopped between the through-flow channel 10 and the first air outlet 21 to shield the first air outlet 21, so that the first air outlet 21 is in a closed state, and at this time, the airflow in the through-flow channel 10 only flows out through the second air outlet 22; when the flow distribution plate 30 moves to a position opposite to the second air outlet 22, the flow distribution plate 30 is stopped between the through-flow channel 10 and the second air outlet 22 to shield the second air outlet 22, so that the second air outlet 22 is in a closed state, and at this time, the airflow in the through-flow channel 10 only flows out through the first air outlet 21. The diversion plate 30 may also be kept in a moving state, so that each air outlet 20 is periodically switched between a closed state and an open state to realize dynamic flow air supply. It can be seen that the air-out mode of the cabinet air conditioner with the air-out mechanism of this application is diversified, and the problem that the air-out mode of the cabinet air conditioner in the prior art is single is solved.
