and the air flow driving device 300 is used for driving the air flow to enter the secondary air duct 230 from the secondary air inlet 240.
The housing 100 is provided in a cylindrical shape, for example, a pseudo-cylindrical shape, which is a cylindrical shape and has a small number of protruding or recessed portions according to actual needs. The primary air inlet 110 is disposed on a side of the housing 100 facing away from the user, but may be disposed on a side or a top of the housing 100 in some embodiments. The main air outlet is arranged on the cylindrical surface and is rectangular. The main air outlets include a first main air outlet and a second main air outlet 130. The heat exchanger and the wind wheel of the double cross-flow air conditioner are both arranged along the length direction of the casing 100, and the heat exchanger is connected with one end of the volute 400 close to the main air inlet 110 so as to surround the cross-flow wind wheel 500. Specifically, the heat exchanger is arranged in a U shape, the cross-flow wind wheel 500 is located at the U-shaped opening, and one end of the volute 400 is fixedly connected with one end of the heat exchanger away from the main air inlet 110, so that the air flow after heat exchange circulates along an air channel surrounded by the volute 400. The arrangement is beneficial to improving the heat exchange efficiency of the heat exchanger and the air guide efficiency of the volute 400. Of course, due to the double cross flow. Two cross-flow wind wheels 500 are arranged in parallel in the housing 100, and a volute 400 is arranged for each cross-flow wind wheel 500, and corresponds to a main air duct, namely the first main air duct 140 and the second main air duct 150 mentioned above.

The airflow driving device 300 is a driving device for driving an airflow such as a centrifugal fan or a fan. The airflow driving device 300 is disposed in the secondary air duct 230 or corresponding to the secondary air outlet 250, so that part of the airflow in the primary air duct enters the secondary air duct 230 from the secondary air inlet 240, and simultaneously the airflow in the secondary air duct 230 is discharged from the secondary air outlet 250.
After the airflow driving device 300 is turned on, air is sucked from the position of the auxiliary air inlet 240 through the auxiliary air duct 230 system, so that a certain negative pressure is formed at the position of the first main air outlet 120 or the second main air outlet 130 corresponding to the auxiliary air inlet 240, and under the action of air pressure, the wind direction at the first main air outlet 120 or the second main air outlet 130 is changed, so that the airflow in the first main air duct 150 or the second main air duct 150 deviates towards the direction with smaller air pressure, namely deviates from the front to one side, thereby achieving the purpose of adjusting the air outlet direction; the negative pressure can be adjusted by adjusting the power of the airflow driving device 300, so that the wind direction deviation, namely the air outlet direction, can be adjusted; through negative pressure wind-guiding for the direction change of air current is accomplished under the effect of atmospheric pressure, avoids air current and entity to carry out extrusion and friction, thereby has reduced the energy consumption of air current at the diversion in-process by a wide margin, thereby is favorable to improving the amount of wind, keeps the wind speed, is favorable to the user to flow the air current to assigned position far away. Meanwhile, compared with the air guide plate for guiding air, the air guide plate is not limited by the rotation angle of the air guide plate, so that the air guide range is greatly increased.
In order to improve the air guiding effect of the secondary air duct 230 system, the secondary air inlet 240 extends along the height direction of the housing 100, and the secondary air inlet 240 is opened toward the main air outlet of the first main air duct 140 or the second main air duct 150. In this embodiment, the secondary air inlet 240 extends along the height direction of the housing 100, so that the air flow can enter the secondary air duct 230 along the length direction of the first main air outlet 120 or the second main air outlet 130 under the action of the air flow driving device 300, and the negative pressure region formed by air suction is arranged along the length direction of the first main air outlet 120 or the second main air outlet 130, so that the air flow flowing out along the first main air outlet 120 or the second main air outlet 130 can be influenced by negative pressure, and thus the guiding of the air flow is more prepared and comprehensive, and the air guiding effect of the secondary air duct 230 system is favorably improved.
In order to improve the fluidity of the airflow in the secondary air duct 230, the secondary air outlet 250 is provided on the housing 100 along the height direction of the housing 100, or on the top and/or bottom of the secondary air duct 230. In this embodiment, the air flow in the auxiliary duct 230 may be discharged out of the auxiliary duct 230 along the length direction of the auxiliary duct 230, or may be discharged out of the auxiliary duct 230 from both ends of the auxiliary duct 230. The air is discharged from both ends of the sub duct 230 or one side of the sub duct 230 by the flow guide of the inner wall of the sub duct 230 and the driving of the airflow driving device 300. Taking the case where the airflow driving device 300 is provided at both ends of the casing 100 as an example, the airflow driving device 300 draws the airflow in the secondary air duct 230 from the end of the secondary air duct 230.

The volute 400 is connected with a heat exchanger of an indoor unit of a cross-flow air conditioner, the cross-flow wind wheel 500 is arranged in the volute 400, and under the action of the cross-flow wind wheel 500, airflow passes through the heat exchanger and then flows along the inner surface of the volute 400. The flow guiding surface is connected to a side of the spiral case 400 away from the heat exchanger, so that the air flows along the flow guiding surface after leaving the inner wall surface of the spiral case 400, and the air flows pass through the secondary air inlet 240 in the process of guiding the air flow out of the main air outlet by the flow guiding surface. Through the arrangement of the flow guide part 200, the air flow can be better guided under the action of negative pressure.
In order to improve the stability of the installation of the airflow guide 200 and the housing 100, the connection portion 210 has an installation surface, and the installation surface is attached and fixed to the inner wall of the housing 100. By the attaching arrangement, the connection area of the guide member 200 and the housing 100 is increased, thereby improving the stability after installation.
In order to make the airflow in the first main air duct 140 or the second main air duct 150 flow more smoothly, the drainage portion abuts against the scroll 400 to form a side wall of the first main air duct 140 or the second main air duct 150. When the drainage portion abuts against the volute 400, the airflow flowing out from the inner wall surface of the volute 400 directly flows into the flow guide surface of the guide portion, so that the airflow is stably transited.
Of course, in some embodiments, to reduce the machining process of the baffle 200, the baffle 200 is integrally formed with the housing 100.

The left and right sides of the first main air outlet 120 and the left and right sides of the second main air outlet 130 are provided with the auxiliary air ducts 230, so that the four auxiliary air ducts 230 guide the air of the first main air outlet 120 and the air of the second main air outlet 130.
In order to enable the airflow in the first main air duct 140 or the second main air duct 150 to be guided in a shunting manner, the dual-through-flow air conditioner further includes a shunting member disposed along the height direction of the casing 100, the shunting member is disposed in the first main air duct 140 corresponding to the first main air outlet 120, or disposed in the second main air duct 150 corresponding to the second main air outlet 130, so as to partition the first main air duct 140 or the second main air duct 150 into two sub-air ducts, and the secondary air inlets 240 of the two secondary air ducts 230 are respectively communicated with the two sub-air ducts.

Through the arrangement of the flow dividing piece, airflow in the sub-air ducts cannot generate turbulence and the like due to the effect of the plurality of auxiliary air ducts 230 on colleagues, and more accurate and efficient air supply of the air conditioner is facilitated.
In order to improve the air supply efficiency of each sub-air duct, the flow dividing member comprises a first flow guiding part and a second flow guiding part, the first flow guiding part is provided with a first flow guiding surface facing one flow guiding member 200, and the second flow guiding part is provided with a second flow guiding surface facing the other flow guiding member 200;

The extending directions of the first guiding surface and the guiding surface of one guiding element 200 are close to each other, so that the air flow is guided to the same direction, and the air flow can flow more smoothly in the sub-air duct. Similarly, the second guiding surface and the guiding surface of the other guiding element 200 serve as the side wall of the other sub-air duct to guide the flow of the air flow together. The extending direction of the second guiding surface is close to that of the guiding surface of the other guiding member 200, so that the air flow is guided to the same direction, and the air flow can flow more smoothly in the sub-air duct.
