The first wind wheel is used for driving airflow in the air duct to flow to the first air outlet 102, optionally, the first wind wheel is a cross-flow wind wheel 21, the cross-flow wind wheel 21 is arranged in the air duct, and an axis of the cross-flow wind wheel 21 extends in the up-and-down direction. The second wind wheel 22 is used for driving the airflow in the air duct to flow to the second air outlet 103, optionally, the second wind wheel 22 is an axial flow wind wheel or an oblique flow wind wheel, and the second wind wheel 22 is arranged in the air duct and above the cross flow wind wheel 21. It will be appreciated that both the first and second wind wheels may be driven by an electric motor. For example, the indoor unit of the air conditioner includes a driving device having a first driving shaft 31 and a second driving shaft 32, the first driving shaft 31 is connected to the cross flow wind wheel 21 for driving the cross flow wind wheel 21 to rotate, and the second driving shaft 32 is connected to the second wind wheel 22 for driving the second wind wheel 22 to rotate.

When the driving device drives the cross flow wind wheel 21 to rotate through the first driving shaft 31, the cross flow wind wheel 21 drives the airflow in the air duct to flow to the first air outlet 102, when the air conditioner is in a cooling mode, cold air is blown out from the first air outlet 102, and if the air conditioner is in a no-wind-sense mode, the indoor temperature is slowly reduced, and even the temperature rises. At this time, in the air-conditioning indoor unit 100 of this embodiment, the second driving shaft 32 of the driving device can be used to drive the second wind wheel 22 to rotate, the second wind wheel 22 drives the cold air in the air duct to flow to the second air outlet 103 and blow out from the second air outlet 103, and the cold air blown out from the second air outlet 103 can not only quickly reduce the indoor temperature, but also cannot directly blow people with uncomfortable feeling from the first cold air because the second air outlet 103 is disposed at the top of the air-conditioning indoor unit 100.

Referring to fig. 2, the flow guiding ring 8 is disposed between the second wind wheel 22 and the second wind outlet 103, a flow guiding channel 801 is formed in the flow guiding ring 8, the flow guiding ring 8 guides the airflow at the position of the second wind wheel 22 to the second wind outlet 103 through the flow guiding channel 801, and as shown in fig. 13, the cross-sectional dimension of at least a part of the flow guiding channel 801 is tapered in the flowing direction of the airflow (for example, in the direction from bottom to top shown in fig. 13). That is, the cross-sectional size of only a part of the flow guide channel 801 may be gradually reduced, or the cross-sectional size of the entire flow guide channel 801 may be gradually reduced. By reducing the cross-sectional dimension of the flow guide channel 801 of the flow guide ring 8, when the airflow flows to the second air outlet 103 through the flow guide channel 801, the wind speed at the position of the second air outlet 103 can be increased, and the air supply distance can be increased, so that the disturbance and convection to the air in the room can be enhanced.

According to the utility model discloses machine 100 in air conditioning blows off from second air outlet 103 through the air current with in the wind channel, can improve the travelling comfort when the air conditioner refrigerates, improves the refrigeration ability under the no wind sense mode of air conditioner. In addition, the air speed of the second air outlet can be increased by the guide ring, the air supply distance is increased, and the disturbance and convection to the air in the room are further increased.

In one embodiment of the present invention, the ratio of the cross-sectional area of the outlet of the deflector ring 8 to the cross-sectional area of the inlet of the deflector ring 8 is in the range of 0.5-0.9. That is, the ratio of the cross-sectional area of the guide passage outlet to the cross-sectional area of the guide passage inlet is in the range of 0.5 to 0.9, in other words, the cross-sectional area of the guide passage outlet is 50 to 90% of the cross-sectional area of the inlet. For example, the cross-sectional area of the flow guide channel outlet may be 60%, 70%, 80%, or the like of the inlet cross-sectional area. Therefore, the air speed of the second air outlet 103 can be effectively improved, and the air output of the position of the second air outlet 103 is ensured.

in some embodiments, the second air outlet 103 is formed on the top of the housing 1, and/or the second air outlet 103 is formed on the top of the front side of the housing 1. That is, the second outlet 103 may be formed only on the top of the housing 1, the second outlet 103 may be formed only on the front side of the housing 1, or the second outlet 103 may be formed on both the top of the housing 1 and the front side of the housing 1. Therefore, the position of the second air outlet 103 can be flexibly set. For example, in fig. 3, the second outlet 103 is formed on the ceiling of the top of the housing 1, and as shown in fig. 9 and 10, the second outlet 103 is formed on the top of the front side of the housing 1.

Therefore, the guide ring 8 is simple in structure and convenient to process and manufacture. For example, the baffle ring 8 may be formed in a shape of a rotating body having an axis extending in the vertical direction and both ends open, the connection section 81 may be formed in a cylindrical shape, and the contraction section 82 may be connected to the upper end of the connection section 81 so as to gradually decrease in cross-sectional area.

In some embodiments, as shown in fig. 14, the second air outlet 103 is located on the front side of the housing 1, and the flow guide channel 801 is formed into an arc-shaped channel with a gradually decreasing flow cross section in a direction from the second wind wheel 22 toward the second air outlet 103. Therefore, the resistance of the flow guide channel to the fluid can be reduced, and the wind speed of the second air outlet 103 can be further improved.

according to some embodiments of the present invention, the indoor unit of air conditioner 100 may further include: and the air guide mechanism is arranged at the position of the second air outlet 103, is configured to guide the air flow of the second air outlet 103 to blow in a forward and upward direction, and/or is configured to make the air flow of the second air outlet 103 swing in a horizontal direction. That is, the air guide mechanism may direct the air flow of the second outlet 103 only in the forward and upward direction and may cause the air flow of the second outlet 103 only to swing in the horizontal direction. The air guide mechanism can also guide the airflow of the second air outlet 103 to blow out in a forward and upward direction, and simultaneously make the airflow of the second air outlet 103 swing in a horizontal direction. The air flow blows forwards and upwards, the air supply distance can be increased, ceiling settlement refrigeration is realized, air supply can be realized leftwards and rightwards by swinging the air flow in the horizontal direction, the air supply range is improved, and disturbance of the air flow in a room is enhanced.

In some examples, as shown in fig. 13, the wind guide mechanism may include: and the air deflector 5 is arranged at the second air outlet 103 and used for opening and closing the second air outlet 103, and when the air deflector 5 opens the second air outlet 103, the air deflector extends obliquely in the forward and upward direction. At this time, the air deflector 5 can guide the airflow of the second air outlet 103 to blow out in the upward and forward direction, so that cold air can be prevented from directly blowing to the human body, and the comfort is improved.

In some examples, as shown in fig. 12, the second air outlet 103 is formed at the front side of the housing 1, and the air guide mechanism may include: and the air guide louver 51 is arranged on the inner side of the second air outlet 103 in a rotatable manner around a vertical axis of the air guide louver 51. When the air guide louver 51 rotates around the vertical axis, the direction of the airflow blown out from the second air outlet 103 can be changed in real time, so that the airflow blown out from the second air outlet 103 can swing.

In some embodiments, the air guide mechanism may include: and the grating plate 9 is connected with the shell 1, and an air guide grating opposite to the second air outlet 103 is formed on the grating plate 9.

Thus, in some embodiments, referring to fig. 11, the spacing between two adjacent transverse air guiding ribs 91 is in the range of 5mm-35 mm. Therefore, the guiding function of the transverse air guiding ribs 91 on the air flow can be ensured, and meanwhile, the resistance of the air guiding grille on the air flow is reduced. For example, the spacing between the two transverse wind guiding ribs 91 may be 8mm, 12mm, 16mm, 20mm, 24mm, 28mm, 32mm, and so on.

In some examples, the included angle between the transverse air guiding rib 91 and the horizontal plane is in a range of 1 ° to 40 °, that is, the angle of upward inclination of the transverse air guiding rib 91 is in a range of 1 ° to 40 °. In some examples, the included angle between the transverse air guiding rib 91 and the horizontal plane is in a range of 0 ° to 30 °, that is, the angle of upward inclination of the transverse air guiding rib 91 is in a range of 0 ° to 30 °. Therefore, the air supply distance of the second air outlet 103 can be effectively increased. For example, the included angle between the transverse air guiding rib 91 and the horizontal plane may be 5 °, 10 °, 15 °, 20 °, 25 °, 35 °, and so on.

When the grating plate 9 rotates in the horizontal direction, the vertical air guiding ribs 92 also rotate along with the grating plate, so that the relative positions and the relative angles of the vertical air guiding ribs 92 can be adjusted, the effect of guiding air flow is achieved, air swinging is achieved, and the air supply range is improved.

In one embodiment of the present invention, the axis of the cross-flow wind wheel 21 coincides with the axis of the second wind wheel 22. In the rotating process of the second wind wheel 22 and the cross-flow wind wheel 21 which are coaxially arranged, the rotating central shafts are the same, so that the stability of the airflow in the air duct can be improved, and the rotating stability of the second wind wheel 22 and the cross-flow wind wheel 21 is improved.
