Fig. 1 is a schematic front view of an indoor unit of an air conditioner according to an embodiment of the present utility model, and referring to fig. 2 to 9, the indoor unit of an air conditioner according to an embodiment of the present utility model includes two side-by-side air outlet portions 10 and two air guiding devices 12. Each air outlet portion 10 extends along the vertical direction, and a first air outlet 11 in a vertical bar shape is formed in the front side of each air outlet portion 10. The two first air outlets 11 are symmetrically arranged about a first reference plane extending vertically and back and forth. The two vertical edges of the first air outlet 11 are a first edge and a second edge respectively, the second edge is positioned on one side of the first edge far away from the other air outlet 10, and a forward included angle between a plane where the first edge and the second edge are positioned and a first reference plane is an acute angle. Each wind guiding means 12 is arranged at a corresponding first wind outlet 11 for guiding wind in a lateral direction. The air deflector 12 comprises a first air deflector 121 and a second air deflector 122, the first air deflector 121 being proximate to a first reference plane. In some embodiments, the forward angle between the plane in which the first and second edges lie and the first reference plane is preferably 60 ° to 80 °.

During operation, the air guiding device 12 guides the transverse air outlet of the first air outlet 11, and because the forward included angle between the plane where the first edge and the second edge are located and the first reference plane is an acute angle, especially when the acute angle is 60 ° to 80 °, the arrangement makes the first air outlet 11 be "front", so that the air flow blown out from the first air outlet 11 is more front and can flow to two sides, and the arrangement is beneficial to increasing the air outlet angle of the indoor unit of the air conditioner so as to meet the requirement of users.

In some embodiments of the present utility model, the two air outlet portions 10 are spaced apart such that an induced air space 20 is formed between the two air outlet portions 10.

In some embodiments of the present utility model, the first air deflector 121 and the second air deflector 122 are arranged so as to be rotatable to a first position in which the first air deflector 121 blows air forward, the second air deflector 122 blows air forward obliquely away from the first reference plane, and a forward angle between a plane in which two vertical edges of the second air deflector 122 lie and the first reference plane is greater than or equal to 45 °.

In some embodiments, as shown in fig. 7, the first position may be a position where the air outlet portion blows out wide-angle uniform air. The first air deflector 121 guides the air flow blown forward from the air guiding portion, so that the air in the air guiding space 20 can be driven to flow forward, and the two air flows are mixed to play a role of homogenizing air. Meanwhile, the second air deflector 122 directs the air flow to blow in the direction away from the first reference plane, thereby enlarging the air outlet angle and playing a role of wide-angle air outlet. In the first position, the air flow blown out by the forward air outlet part 10 and the air flowing out of the air inducing space 20 forward are provided, and the blown air flow with the expanded air outlet angle generally plays a role in wide-angle air homogenization.

In other embodiments of the present utility model, in the first position, the first air deflector 121 blows air in a diagonally forward direction near the first reference plane. This arrangement also drives the air in the induced air space 20 forward, and the two airflows mix to achieve the effect of homogenizing the air.

Further, in some embodiments of the present utility model, the air outlet 10 is provided with a second reference plane, and the second reference plane is a vertical plane perpendicular to the first reference plane. In the first position, the forward included angle between the plane in which the two vertical edges of the first air deflector 121 are located and the second reference plane is B, and B is 75 ° to 90 °. Preferably, B is 85 °. In the first position, the forward included angle between the plane in which the two vertical edges of the second air deflector 122 are located and the second reference plane is a, and a is 40 ° to 45 °. Preferably, a is 42 °.

In some embodiments of the present utility model, each air outlet 10 includes a first air guiding surface 32 connected to a second edge, the first air guiding surface 32 including a second edge and a third edge, the second edge being diagonally behind the third edge. In the first position, the edge of the second air deflection 122 that is proximate to the first air deflection 32 is on the front side of the first air deflection 32. In these embodiments, in the first position, the second air deflection plate 122 and the first air deflection surface 32 define a wide-angle air deflection position of the wide-angle air duct, which is more advantageous for enlarging the wide-angle air supply angle of the air outlet portion 10. Meanwhile, the arrangement is also beneficial to solving the problem of condensation possibly generated and ensuring the quality of the whole product. When the second air deflector is positioned at the first position for a long time, condensation can not be generated on the first air deflector surface. If condensation is generated on the first air guide surface, the condensation can be blown away by moving the second air guide plate to the first position.

In some embodiments of the present utility model, when the forward included angle between the plane in which the two vertical edges of the second air deflector 122 are located and the second reference plane is smaller than 60 °, the edge of the second air deflector 122 close to the first air deflector 32 is located at the front side of the first air deflector 32. That is, when the forward included angle between the plane of the vertical edge of the second air guiding plate 122 and the second reference plane is smaller than 60 °, the second air guiding plate 122 and the first air guiding surface 32 always define the wide-angle air guiding position of the wide-angle air duct, which is beneficial to enlarging the wide-angle air supplying angle of the air outlet 10.

In some embodiments of the present utility model, as shown in fig. 7, the first air guiding surface 32 is an arc surface, and the radius of the arc surface is R, where R is 50 mm to 55 mm. Preferably, R is 52 mm.

In some embodiments of the present utility model, the first air deflector 121 and the second air deflector 122 are arranged so as to be rotatable to a second position in which the first air deflector 121 blows air in a diagonally forward direction away from the first reference plane, the second air deflector 122 blows air in a diagonally forward direction away from the first reference plane, and a forward angle between a plane in which a vertical edge of the second air deflector 122 is located and the first reference plane is greater than or equal to 45 °.

In some embodiments, as shown in fig. 8, the second position may be a position in which the blown wide angle embraces the wind. The first air deflector 121 and the second air deflector 122 both guide the air flow to blow in the oblique front direction far away from the first reference plane, so that the air outlet angle is enlarged, that is, the air outlet of the two air outlet portions 10 are both in the direction far away from each other, so that surrounding air is formed, direct blowing of users in front of the air outlet portions 10 is avoided, and the use feeling of the users can be improved. As shown in fig. 9, the air flow blown out from the first air outlet and the air flow blown out from the second air outlet may also be mixed together.

Further, in some embodiments of the present utility model, in the second position, the forward included angle between the plane in which the two vertical edges of the first air deflector 121 lie and the second reference plane is B, and B is 60 ° to 75 °. Preferably, B is 70 °. The forward included angle between the plane in which the two vertical edges of the second air deflector 122 are located and the second reference plane is a, and a is 30 ° to 40 °. Preferably, a is 35 °. The forward included angle between the plane of the two vertical edges of the second air deflector 122 and the second reference plane is smaller than the forward included angle between the plane of the two vertical edges of the second air deflector 122 and the second reference plane when the second air deflector is in the first position.

In these embodiments, the wide angle air channel defined by the second air guiding plate 122 and the first air guiding surface 32 when the second air guiding plate 122 moves to the second position is smaller than the wide angle air channel defined by the second air guiding plate 122 and the first air guiding surface 32 when the second air guiding plate 122 moves to the first position, which is beneficial to increasing the speed of the air flow flowing out of the wide angle air channel, thereby being beneficial to increasing the air supply distance.

In some embodiments of the utility model, in the second position, the edge of the second air deflection 122 closest to the first air deflection 32 is on the front side of the first air deflection 32. In the second position, the second air guiding plate 122 and the first air guiding surface 32 define a wide-angle air guiding position of the wide-angle air duct, and this arrangement is also beneficial to enlarging the wide-angle air supply angle of the air outlet portion 10.

In some embodiments of the present utility model, each air outlet portion 10 further includes a second air outlet 17 in a vertical bar shape. The second air outlet 17 is arranged at the front side of the air outlet part 10, and the second air outlet 17 is arranged at one side of the first air outlet 11 far away from the other air outlet 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 away from the first air outlet. 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. 4, the air outlet structure 18 includes a plurality of arcuate plates, where the arcuate plates are disposed in parallel, and the arcuate plates are spaced apart to form a plurality of outflow holes at the second air outlet, and the air flow passing through the second air outlet flows out through the plurality of outflow holes. The plurality of arc plates are protruded towards the front of the first air outlet 11, so that the air outlet 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.

In some embodiments of the utility model, the forward angle between the tangential plane at the front edge of the arcuate plate and the second reference plane is C, C being 15 ° to 20 °. Preferably, C is 18 °. The angle of the arc plate is favorable for enlarging the air outlet angle of the second air outlet 17.

In some embodiments of the utility model, the ratio of the width D of the outflow hole to the width D of the second air outlet 17 is 0.4 to 0.8. Preferably, the ratio of the width D of the outflow hole to the width D of the second air outlet 17 is 0.6.

In some embodiments of the present utility model, each of the air outlet portions 10 further includes an air outlet base portion and an air guide 30. The front side of the air outlet main part is provided with a communication port extending along the length direction of the air outlet main part. The communication port has a first edge and a fourth edge extending in the longitudinal direction of the air outlet base portion and away from the other air outlet portion 10.

Between the fifth edge and the third edge is a second air outlet 17. The bypass duct communicates the communication port with the second air outlet 17. When the air conditioner works, air flows out from the communication port and flows out through the first air outlet and the second air outlet, so that the air outlet area is enlarged, and the air outlet angle is increased.

In some embodiments of the utility model, as shown in FIG. 2, an air intake structure 19 is provided at the inlet of the bypass duct to break up the wind passing through the inlet of the bypass duct.

Further, in some embodiments of the present utility model, as shown in fig. 1, the air intake structure 19 is a microplate, and two edges of the microplate along the length direction are connected to the fourth edge and the second edge, respectively. Part of the air outlet of the 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 wind guiding body 30 further includes a second wind guiding surface 31 located at a rear side of the first wind guiding surface 32, where the first wind guiding surface 32 is a cambered surface arched away from the bypass duct. The second air guiding surface 31 has a planar area connected to the second edge, and an end of the planar area away from the first edge is obliquely in front of the second 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 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 present utility model, an air inlet 16 is provided on the side wall of each air outlet base portion, which communicates with the communication port. 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.

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 first air deflector 121 extends back and forth, and the second air deflector 122 forms a wide-angle air duct with the first air guiding surface 32, so that an 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-angle air homogenizing mode.
