Vortex ring generating device, air conditioner indoor unit and air conditioner

Abstract

The invention discloses a vortex ring generating device, an air conditioner indoor unit and an air conditioner. The vortex ring generating device comprises a flow gathering member, a louver ring and alouver driving mechanism; the flow gathering member is provided with a first port and a second port; the wind blowing area of the second port is smaller than that of the first port; the louver ring is arranged at the first port, and includes a mounting ring and multiple blades; the multiple blades are arranged in the circumferential direction of the mounting ring; each blade has a rotating end connected with the mounting ring, and a free end rotating around the rotating end; the louver ring has a closed state that the free ends of all the blades get close to a plane where the mounting ring islocated so as to close the first port, and an open state that the free ends of all the blades move away from the first port and get close to the second port; and the louver driving mechanism drives the louver ring to be periodically switched between the open state and the closed state. In the switching process of the louver ring from the closed state to the open state, the rotation direction of each blade is consistent with an air supply direction, so that disturbance to airflow is small, and the vortex ring forming effect is good.

Description

Technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a vortex ring generator, an air conditioner indoor unit and an air conditioner. Background technique [0002] The existing air conditioner blows the air after the heat exchange through the conventional air outlet of the air conditioner. The air outlet method is the conventional air outlet, while the air flow from the conventional air outlet is fixed, and its radiation range is short and narrow, which cannot achieve a large range. And long-distance air supply reduces the user experience. [0003] Long-distance air supply can be realized by installing a vortex ring generator on the air conditioner. Specifically, the vortex ring is formed by driving the airflow to periodically flow through the collector. The general way of driving the airflow includes setting a switch door at the air inlet of the current collector, and setting an air supply component on one side of the sw...

Problems solved by technology

However, during the opening and closing process of the opening and closing door, since the moving direction of the opening and closing door is inconsistent with the air supply direction, it is easy to disturb the air flow and affect the forming effect of the vortex ring
