The air flow in the indoor unit can be integrated into one air flow and then discharged out of the shell through the fan part, so that the problem that the indoor unit generates surge can be effectively avoided, the noise of the indoor unit is effectively reduced, and the use experience of a user is improved.
As shown in fig. 3, the flow guiding portion 40 has a convex hull structure, and the length direction of the convex hull structure extends along the axial direction of the fan portion 30. This arrangement allows the air flow from above the fan section to be completely integrated into one air flow before it is blown out of the housing by the fan.
The housing 10 has a front shell 13 and a rear shell 14, a first end of the heat exchanger 20 is connected to the front shell 13, a second end of the heat exchanger 20 is connected to the rear shell 14, a convex hull structure is connected to the rear shell 14, and the convex hull structure is convexly arranged toward one side of the front shell 13. This arrangement enables the airflow after the integration of the convex hull structure to flow toward the front shell side, improving the connection stability of the convex hull structure and the rear shell 14.
Specifically, as shown in FIG. 1, the curvature radius of the outer surface molded line of the convex hull structure is R, wherein R is more than or equal to 35mm and less than or equal to 37mm. The minimum distance between the convex hull structure and the front shell 13 is L, wherein L is more than or equal to 85mm and less than or equal to 87mm.

The arrangement can effectively improve the air inlet and outlet of the indoor unit, and further effectively improve the performance of the indoor unit.
The air conditioner adopting the structure solves the problem that the air duct of the upper and lower air outlet wall hanging machine has surge. By adding the flow guide structure above the volute throat of the air duct, two air flows in the air duct are seamlessly fused, so that the two air flows are ensured not to fight against the frame, and no surge noise is generated. Under the condition that the size ratio of the air inlet to the air outlet is 2:1, the radius R35-37mm of the convex hull arc of the flow guiding structure is 63-65 mm, the distance from the arc to the front shell is 85-87 mm, and the flow guiding structure is a part of the water receiving disc of the whole air channel, is integrated in structural design, can be produced and taken out of the mould together, reduces the cost and improves the production efficiency.
Because the air inlet of the upper and lower air outlet air channels (upper and lower cross-flow fans) is twice the air outlet, the air inlet quantity is smaller, the air inlet cannot keep up with the air outlet quantity, and because of the limitation of the air channels, the heat exchanger divides the air inlet into two halves and finally merges above the cross-flow fan blades, if the second air flow passes through the heat exchanger to collide with the first air flow, surging can be generated. When the upper air inlet and the lower air outlet are realized, the flow guiding structure plays a great role, and two airflows at two sides of the heat exchanger are seamlessly fused together, so that the problem of air duct shock is solved. When the lower air inlet and the upper air outlet are provided, water is not received from the upper part, and the heat exchanger is arranged in a mode that the air flow from the heat exchanger to the upper through flow is one, and the flow guiding structure of the lower air channel basically has no influence on the noise of the upper air outlet. In order to ensure the appearance, the indoor unit is arranged in a mode with the same size from top to bottom, in order to solve the problem of dyspnea, the area ratio of the air inlet to the air outlet is set to be 2:1, and meanwhile, a flow guide structure is arranged. The air inlet and the air outlet are switched back and forth during upper air outlet and lower air outlet, a switching mechanism is arranged at the air inlet, the proportion of the air inlet to the air outlet is always guaranteed to be 2:1, the gap between the volute throat and the front shell is 85mm-87mm during lower air outlet, the radian of the convex hull is R35-37 mm, and the height of the convex hull is 63mm-65mm optimally.
According to another embodiment of the present application, the indoor unit further includes a switching mechanism. The switching mechanism is movably arranged at the upper air opening 11 and the lower air opening 12, namely, each air opening position is provided with a switching mechanism, the switching mechanism is used for changing the air opening sizes of the upper air opening 11 and the lower air opening 12, when the upper air opening 11 is used for air inlet and the lower air opening 12 are used for air outlet, the switching mechanism acts to enable the air inlet area ratio of the upper air opening 11 to the air outlet area ratio of the lower air opening 12 to be 2:1, or when the lower air opening 12 is used for air inlet and the upper air opening 11 are used for air outlet, the switching mechanism acts to enable the air outlet area ratio of the upper air opening 11 to the air inlet area ratio of the lower air opening 12 to be 1:2. The switching mechanism can be a wind shield and a driving motor, and the wind shield is driven by the driving motor to reciprocate at the upper wind gap and the lower wind gap, so that the wind outlet area of the upper wind gap and the lower wind gap can be changed. Of course, the switching mechanism may be provided only at one tuyere, and the tuyere ratio may be adjusted.
The indoor unit adopting the structure effectively solves the problems that the air output of the indoor unit is small, and the indoor unit is easy to generate noise of surging and gurgling. The air conditioner adopting the structure can effectively improve the indoor temperature rise and temperature drop speed. The air duct structure design adopting the structure is adopted. The air outlet device has the advantages that the relation between the angle of the diffusion angle and the length of the air outlet and the diffusion section is controlled, so that the optimal air outlet effect and comfort are achieved, the noise of the indoor unit is reduced, and the optimal experience effect is achieved for users. Through adjusting the cooperation of diffusion angle, diffusion section length and wind channel air outlet width, diffusion section length and wind channel width ratio be 3.8 promptly: 1, realize the interior machine air conditioner of high performance when the diffusion angle is 0, both guarantee the air-out amount of wind and solve the noise problem.
Table 1 relation between air volume and diffusion angle
The diffusion angle of the air outlet of the air duct is 0 degrees, namely the air outlets are parallel (as shown in figure 1), and in the same air duct structure, the smaller the diffusion angle is, the larger the air flow speed is, the maximum working efficiency of the air conditioner is improved, and the comfortableness is ensured. The diffusion angle of the traditional indoor unit is between 15 degrees and 25 degrees, the wind blown out from the air outlet is dispersed, the rising and falling speed of the temperature rise is slower, and the use comfort of consumers is poor. The internal machine is easy to surge during operation in the angle interval, and is accompanied with gurgling noise, compared with the traditional internal machine, the point diffusion angle of the invention is designed to be 0 degree (the air outlet is in a parallel state), the energy loss is less during operation, the air outlet is concentrated, and the air quantity is larger. The air outlet is in parallel state, so that no surging exists, and the problem of gurgling noise is solved. As can be seen from the data (shown in fig. 2), the air volume at each rotation speed is compared when the diffusion angle is 0 °.
When the traditional indoor unit runs, surge sound exists, as shown in fig. 1, the length of the diffusion section is 95mm, the width of the air duct is 25mm, the ratio of the length of the diffusion section to the width of the air duct is 3.8:1, and a large number of experimental analysis proves that the ratio of the length of the diffusion section to the width of the air outlet is 3.8:1 is the optimal state where wind speed is maximum, no surge, and noise is minimum. Through a series of structural settings, can guarantee the amount of wind in the time, noise reduction by a wide margin to can promote user's use experience, and then strengthen the market competition of air conditioner
