Further preferably, in some embodiments, the ratio of the distance H in the lateral direction from the first edge to the second edge to the maximum thickness H of the air outlet 10 in the lateral direction is equal to 0.64.

In these embodiments, the air outlet ranges of the first air outlet 11 and the second air outlet 17 are ensured by setting the ratio of the distance H between the first edge and the second edge in the lateral direction to the maximum thickness H of the air outlet 10 in the lateral direction, thereby further expanding the air outlet ranges and the air outlet angles of the indoor unit of the air conditioner.

In some embodiments of the present utility model, as shown in fig. 2, a ratio of a width H1 of the first air outlet 11 to a maximum thickness H of the air outlet 10 in the lateral direction is greater than or equal to 0.2.

In some embodiments of the present utility model, as shown in fig. 4, 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. The two edges of the communication port extending along the length direction are a first edge and a third edge respectively. The surface of the wind-out base 10 includes a wind-guiding region connected to the third edge. The edge of the air guiding area opposite to the third edge is a second edge. The wind guide body 30 is disposed at the front side of the wind guide area. The air guide 30 includes a first air guide surface 32 provided on the front side of the air guide 30. A bypass air duct is arranged between the air guide body 30 and the air guide area. The interval between the first edge and the end of the air guide body 30 having the fourth edge is the first air outlet 11, and the interval between the second edge and the end of the air guide body 30 having the fifth edge is the second air outlet 17. The bypass duct communicates the communication port with the second air outlet 17.

And one part of the air flow passing through the air duct enters the bypass air duct through the communication port and is blown out from the second air outlet, and the other part of the air flow is blown out from the first air outlet.

In some embodiments of the present utility model, as shown in fig. 3 and 4, the second air outlet 17 is provided with an air outlet structure 18. The air outlet structure 18 is a plurality of arc plates, the arc plates are parallel, and the arc plates are protruded towards the front of the first air outlet 11, so that the air flow passing through the arc plates is blown out towards the front side of the second air outlet 17, which is far away from the first air outlet 11. 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.

Further, in some embodiments of the present utility model, as shown in fig. 9, the angle θ between the tangential plane at the front edge of the windward side of the arcuate plate and the vertical reference plane is greater than 50 °.

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.

The wind-guiding body is located at one side of the reference tangent plane far away from the first air outlet. The arrangement is beneficial to wide-angle wind guiding and can not obstruct the wind outlet of the communication port.

In some embodiments of the present utility model, as shown in fig. 1, two air outlet portions are spaced apart such that an induced air space 20 is formed between the two air outlet portions. When the two air outlet parts are used for forward air outlet, the air in the air inducing interval 20 is driven to flow forward by virtue of negative pressure, so that the air and the air outlet blown out by the two air outlet parts are mixed together, the air outlet temperature is reduced during refrigeration, the air is not too hard, and the effect of soft air is generated.

In some embodiments of the utility model, the induced air gap 20 tapers in width from back to front. The above arrangement of the induced air space 20 facilitates the air entering from the rear side of the induced air space 20 and also facilitates the air in the induced air space 20 to be blown out at a faster speed.

In some embodiments of the utility model, an air inlet 16 communicated with the communication port is arranged on the side wall of each air outlet base. 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. As shown in fig. 3, 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 referred to as a breeze mode. As shown in fig. 5, the air guiding device 12 extends along the front-rear direction, the opening area of the first air outlets 11 is the largest, the air outlets of the two first air outlets 11 drive the air in the air guiding space 20 to flow forwards, the air quantity is the largest, and the air outlet mode can be called as the maximum air quantity mode. As shown in fig. 6, 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 forward, so that the wind speed after mixing is greater, which is helpful for supplying air to a far distance, and this air outlet mode may be referred to as a far distance air supply mode. As shown in fig. 7, 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. As shown in fig. 8, the air deflector near the first 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 this air outlet mode may be referred to as a wide-area air homogenizing mode. As shown in fig. 4, one of the air guiding devices is closed, and the other air guiding device guides air, and this air outlet mode may be referred to as a single-unit air supply mode. One of the air guiding devices guides air, the heat exchanger in the other air outlet part is closed, and the air inlet of the other air outlet part is communicated with the indoor environment or the outdoor environment, namely, one air outlet part outputs heat exchange air, and the other air outlet part outputs non-heat exchange indoor air or fresh air, and the air outlet mode can be called a healthy air supply mode.
