When a plurality of air guide blades of the air guide blade mechanism swing to one side (the left side or the right side) by a large angle from an unshielded position, the two ends of the cross-flow wind wheel of the fan can generate surging in the rotating process of the cross-flow wind wheel in the mode. Moreover, when the air deflector of the air deflector mechanism is opened at a small angle, the air outlet is shielded greatly, and the two ends of the cross-flow wind wheel of the fan can also have surge problems in the rotating process of the cross-flow wind wheel in the mode.

The analysis results show that: installation intervals are arranged between two ends of the cross-flow wind wheel and the side wall of the volute, the air quantity of the central area of the air outlet of the fan is far larger than that of the areas of the two ends, when the plurality of air guide blades swing to one side (the left side or the right side) by a large angle from an unshielded position and/or the air guide plates are opened by a small angle, the air in the areas of the left end and the right end of the air outlet can flow backwards into the installation intervals between the two ends of the cross-flow wind wheel and the side wall of the volute under the pressure of the air in the middle area of the air outlet, and therefore the surging of the two ends of the cross-flow wind wheel is caused. However, when the plurality of air guide blades swing to one side (left side or right side) by a small angle from the non-shielding position and the air guide plate is opened by a large angle, air at the installation interval smoothly flows, and smooth air outlet is facilitated.

Fig. 25 shows an air conditioner, in which an air guide vane mechanism is installed in an air outlet 20 of a fan, and an air guide plate mechanism is installed at the air outlet. When a plurality of air guide blades 10 of the air guide blade mechanism swing to one side (left side or right side) by a large angle from an unshielded position, the two ends of the cross-flow wind wheel 30 of the fan have a surge problem in the rotating process of the cross-flow wind wheel 30 in the mode. Moreover, when the air deflector 40 of the air deflector mechanism is opened at a small angle, the air outlet 20 is shielded greatly, and the two ends of the cross-flow wind wheel 30 of the fan can also generate surging in the rotating process of the cross-flow wind wheel 30 in the mode.

The analysis results show that: installation intervals 50 (shown in fig. 25) are arranged between two ends of the cross-flow wind wheel 30 and the side wall of the volute, the air volume in the central area of the fan air outlet 20 is far larger than that in the areas at the two ends, when the plurality of wind guide blades 10 swing to one side (left side or right side) at a larger angle from an unshielded position and/or the wind guide plate 40 is opened at a smaller angle, the air in the areas at the left end and the right end of the air outlet 20 flows backwards into the installation intervals 50 between the two ends of the cross-flow wind wheel 30 and the side wall of the volute under the pressure of the air in the middle area of the air outlet 20, and therefore surging at the two ends of the cross-flow wind wheel 30 is caused. However, when the plurality of air guiding blades 10 swing from the non-shielding position to one side (left side or right side) by a small angle and the air guiding plate 40 is opened by a large angle, the air at the installation space 50 flows smoothly, which is beneficial to smooth air outlet. The air outlet can be understood as an air outlet channel.

As shown in fig. 27, when the plurality of wind guide blades swing from the non-shielding position to the left or right by a small angle and the wind guide plate 410 is opened by a large angle, the cross flow wind wheel 310 rotates, and a first wind flow blowing toward the wind outlet 322 is formed between the wind outlet 322 and the installation space, in this mode, the function board 361 swings toward the wind outlet 322 to a third position to open the installation space and avoid the first wind flow, so that smooth flow of air at the installation space is ensured, and it is also ensured that the function board 361 does not interfere with the first wind flow and blows outward (noise is avoided), and the wind outlet effect of the wind outlet 322 is better in this mode; as shown in fig. 28, when the plurality of wind guide blades swing from the non-blocking position to the left or right by a large angle and/or the wind guide plate 410 is opened by a small angle, the cross-flow wind wheel 310 rotates, a second wind flow blowing toward the installation space is formed between the wind outlet 322 and the installation space, and in this mode, the function board 361 swings toward the installation space to the fourth position to cover the installation space, so that the second wind flow is prevented from flowing back into the installation space, and the problem of surge at two ends of the cross-flow wind wheel 310 is avoided. The air blowing from the air outlet 322 near (near) the end of the air outlet 322 is turned back from the end of the air outlet 322 to the installation space inside the air outlet 322 to form a return air, which is a second air flow.

When the plurality of air guide blades swing to the left side or the right side by a small angle from the non-shielding position and the air guide plate 410 is opened by a large angle, the cross-flow wind wheel 310 rotates, and the first wind flow driving function plate 361 swings to the third position.

When the plurality of air guide blades swing to the left side or the right side by a large angle from the non-shielding position and/or the air guide plate 410 is opened by a small angle, the cross-flow wind wheel 310 rotates, and the second wind flow driving function plate 361 swings to the fourth position. When the functional board 361 is located at the third position, the distance between the end of the functional board 361 far from the functional component 360 and the sidewall of the volute 320 is at least 5mm, so as to ensure that the plurality of wind guide blades swing from the non-shielding position to the left or right by a small angle and the wind guide plate 410 swings by a large angle, the cross flow wind wheel 310 rotates, and the first wind current can smoothly drive the functional board 361 to swing from the fourth position to the third position. Of course, a return spring (not shown in the figure in this embodiment) may be disposed between the functional member and the scroll casing, the functional plate is configured to be returned to the fourth position by the return spring, the first wind blows the functional plate, and the functional plate swings from the fourth position to the third position by overcoming the elastic force of the return spring.
