Fig. 1 is a schematic front view of an air conditioning indoor unit according to an embodiment of the present utility model, and referring to fig. 2 to 4, the air conditioning indoor unit according to an embodiment of the present utility model includes two air outlet portions 10. Each air outlet 10 is provided with a first air outlet 11 in a vertical bar shape, and the two air outlet 10 are arranged at intervals, so that an induced air interval 20 is formed between the two air outlet 10. The entirety of the induced draft interval 20 has a venturi structure.

As shown in fig. 4, the venturi structure includes an inlet section 40, a narrow section 50 and an outlet section 60, wherein arrows indicate fluid flow directions, and fluid entering from the inlet section 40 is accelerated through the narrow section 50 and exits from the outlet section 60. The venturi structure creates a venturi effect, i.e., the velocity of fluid passing through a narrow flow passage increases. In these embodiments, when at least one of the air outlet portions 10 blows the heat exchange air flow forward, the air in the air introducing space 20 is driven forward by the negative pressure. When the air flow in the induced air interval 20 passes through the interval with venturi tube structure, the air flow is accelerated and flows out, so that the air flow is better mixed with the heat exchange air flow of the air outlet part 10, and the temperature of the mixed air flow is closer to the room temperature and is not hard.

In other embodiments of the present utility model, the portion of the induced draft interval 20 is in the form of a venturi structure.

In some embodiments of the present utility model, the full column of the cross-sectional profile of the induced air space 20 is similar to the venturi cross-sectional profile such that the entirety of the induced air space 20 is in the venturi configuration. By "similar" is meant herein that the cross-sectional profile of the induced air space 20 may be sized differently than the cross-sectional profile of the venturi tube, but both conform to the venturi tube structure, and that the airflow flowing within the induced air space 20 may create a venturi effect that accelerates the airflow through the induced air space 20.

Of course, in some embodiments of the utility model, the portion of the cross-sectional profile of the induced draft interval 20 is similar to the venturi cross-sectional profile.

In some embodiments of the present utility model, as shown in fig. 2, the ratio between the distance in the back-and-forth direction of the rear section of the narrowest portion of the cross section of the induced air space 20 and the distance in the back-and-forth direction of the front section is greater than 2. Preferably, the ratio is 2.68. In these embodiments, the arrangement may be such that the position of acceleration of the airflow in the induced air compartment 20 is as forward as possible, thereby allowing the airflow velocity exiting the induced air compartment 20 to be as high as possible to facilitate airflow mixing.

The indoor unit of the air conditioner further comprises two air guiding devices 12, wherein each air guiding device 12 is respectively arranged at the corresponding first air outlet 11, and is used for guiding air out in the width direction of the first air outlet 11 and can move to a wide-angle air guiding position which defines a wide-angle air channel with the first air guiding surface.

In operation, the air guiding device 12 on the air outlet portion 10 rotates to guide the direction of the air blown out from the first air outlet 11, particularly, when the air guiding device 12 rotates to the wide-angle air guiding position, at least one column of air blown out from the first air outlet 11 enters the wide-angle air duct defined by the first air guiding surface 32 and the air guiding device 12 and is blown out in the direction away from the other air outlet portion 10, so that the air outlet angle of the first air outlet 11 is enlarged, and the air outlet angles of the two air outlet portions 10 are further larger, thereby meeting the requirement of users on wide-angle air supply of the indoor unit of the air conditioner.

In some embodiments of the utility model, each air outlet includes an air outlet base and an air guide. The front side of the air-out main part 10 has a communication port extending in the longitudinal direction of the air-out main part 10.

In some embodiments of the present utility model, as shown in fig. 2, an air outlet structure 18 is disposed at the second air outlet 17, and the air outlet structure 18 causes the air outlet passing through the second air outlet 17 to blow out toward the front side of the second air outlet 17 near the third edge. That is, the wind entering the bypass duct can change the wind direction after passing through the wind outlet structure 18, and enlarge the wind outlet angle.

In some embodiments of the present utility model, as shown in fig. 3, the air outlet structure 18 includes a plurality of arc plates, and the plurality of arc plates are disposed in parallel, and the plurality of arc plates protrude toward the front of the first air outlet 11, so that the air outlet passing through the arc plates blows out toward the front side of the second air outlet 17 near the third edge.

Further, in some embodiments of the present utility model, as shown in fig. 2, the air inlet structure 19 is a microplate, and two edges of the microplate along the length direction are connected to the fourth edge and the first edge, respectively. The air outlet of the one-column communication port is scattered by the micropores through the micropore plate to become breeze, so that the air outlet is softer.

In some embodiments of the utility model, the microwells are horizontally disposed.

In some embodiments of the present utility model, as shown in fig. 2, the air guiding body 30 further includes a second air guiding surface 31 located at a rear side of the first air guiding surface 32, where the first air guiding surface is a cambered surface that arches away from the bypass duct. The second air guiding surface 31 has a planar area connected to the fourth edge, and an end of the planar area away from the first edge is obliquely in front of the fourth edge. The second air guiding surface 31 can reduce wind resistance, so that wind entering the bypass air duct through the air inlet structure 19 can be blown out more easily through the air outlet structure 18.

In some embodiments of the present utility model, the air outlet structure 18, the air inlet structure 19, and the air guide are integrally formed.

In some embodiments of the present utility model, as shown in FIG. 3, the air guide 12 includes at least one air guide plate, and when the air guide is moved to the wide angle air guide position, the edge of the air guide plate closest to the air guide 30 is located on the front side of the first air guide surface 32.

A fan is arranged in each air outlet main part, and the fan guides air to enter the air outlet main parts and blow out from the communication ports. The fan is a cross flow fan 14. At least one of the air outlet portions is provided with a heat exchanger 15. When one of the two air outlet parts blows the heat exchange air flow, the non-heat exchange air flow and the air in the induced air interval 20 are mixed in front of the indoor unit of the air conditioner, so that the temperature of the mixed air flow is closer to the room temperature, and the air outlet is soft. When both the two air outlet bases blow the heat exchange air flow, the heat exchange air flow and the air in the induced air interval 20 are mixed in front of the indoor unit of the air conditioner, and the air outlet is soft.

In some embodiments of the present utility model, an air conditioning indoor unit has a plurality of air outlet modes. The air guiding device 12 closes the first air outlet 11, and the air outlet passing through the communication port enters the bypass air duct through the air inlet structure 19 and is blown out from the second air outlet 17 through the air outlet structure 18, and this air outlet mode may be called a breeze mode.

The air outlets of the two first air outlets 11 are directed to each other, and the air outlets of the two first air outlets 11 drive the air in the air inducing space 20 to flow forwards, so that the wind speed after mixing is larger, and the air is beneficial to supplying air to a far distance, and the air outlet mode can be called a far distance air supply mode. As shown in fig. 3, the two air deflectors of the air guiding device 12 are inclined in the direction of the air guiding body 30, and the air outlets of the two first air outlets 11 are facing away from each other, so that the air outlets of the two first air outlets 11 mainly face to two sides, and this air outlet mode may be referred to as a wide-angle encircling air mode. The air deflector near the second edge of the air guiding device 12 extends back and forth, and the air deflector near the air guiding body 30 and the first air guiding surface 32 form a wide-angle air duct, so that the air outlet angle passing through the first air outlet 11 is relatively large, and the air outlet mode can be called a wide-area air homogenizing mode. One of the air guiding devices is closed, the other air guiding device guides air, and the air outlet mode can be called a single-column air supply mode.
