In an embodiment of the present invention, as shown in fig. 1 to fig. 3, the indoor unit of an air conditioner includes: the scroll compressor comprises a shell 10 and a control device, wherein the shell 10 is provided with an air outlet 11, and the shell 10 comprises a rear scroll casing 12 and a front scroll tongue 13 which are respectively arranged on two sides of the air outlet 11 in the width direction; the first air deflector 20 is arranged at the air outlet 11 and close to the rear volute 12, and the first air deflector 20 is a straight plate; the second air deflector 30 is arranged at the air outlet 11 and located between the rear volute 12 and the front volute tongue 13, the second air deflector 30 is an arc plate, and the concave arc surface of the second air deflector 30 faces to one side of the second air deflector 30, which is far away from the front volute tongue 13.
In this embodiment, the housing 10 further has an air inlet, the front volute tongue 13 is located above the rear volute 12, the front volute tongue 13 and the rear volute 12 enclose to form an air duct, and a fan is disposed in the air duct to drive an air flow from the air inlet to the air outlet 11. A heat exchanger is arranged in the casing 10 for exchanging heat and adjusting temperature of the air flow flowing through the air duct. The first air guiding plate 20 and the second air guiding plate 30 are used for adjusting the air outlet direction of the air flow, such as guiding the air downwards. The first air deflector 20 extends along the length direction of the air outlet 11 and is close to the edge of the air outlet end of the rear volute 12, and when the air flow flows to the air outlet 11 along the rear volute 12, the air flow continues to flow in advance along the first air deflector 20, so that the air supply distance is prolonged, and the loss of the air flow when the air flow leaves the air outlet 11 is reduced. In addition, the first air deflector 20 extends the flow path of the airflow, and can also reduce the airflow surge caused when the airflow leaves the air outlet 11, thereby improving the stability of the indoor unit of the air conditioner.
The second air deflector 30 is located between the rear volute 12 and the front volute tongue 13, and the air flow passing through the second air deflector 30 is divided, so that the air flow is effectively guided. Because the second air guiding plate 30 is an arc plate, when the air current contacts the second air guiding plate 30, an included angle is formed between the air current and the arc surface of the second air guiding plate 30, so that the direction of the air current can be changed more easily, and the effective guiding effect on the air current is achieved.
As shown in fig. 5, if no air deflector is disposed at the air outlet of the indoor unit of the air conditioner, the air flow will flow towards the front of the rear volute 12 when leaving the air outlet, and the rear volute 12 is inclined in practical application, so that the air flow will flow towards the upper side, and is not easy to diffuse to the indoor lower space where the user is located, which may affect the user experience. If the concave arc surface of the arc-shaped air deflector faces to one side close to the front volute tongue, namely as shown in fig. 6, when the airflow passes through the air deflector, the wind field suddenly changes, the aerodynamic resistance is large, large aerodynamic loss is caused, and the air outlet efficiency is reduced.
In the air conditioning indoor unit of the present embodiment, as shown in fig. 7, the concave arc surface of the second air deflector 30 faces to the side away from the front volute tongue, so that the cross-sectional curve of the second air deflector 30 is more consistent with the air outlet flow, and the pneumatic loss caused by sudden change of the wind field is not easily generated, thereby guiding the air flow to the preset position and improving the air outlet efficiency. As shown in fig. 4, through detecting the utility model discloses the curve graph that the amount of wind power under the machine two kinds of circumstances in the machine and the no aviation baffle air conditioning of machine in the air conditioning reachs can be known, the utility model discloses the amount of wind power of machine in the air conditioning is lower, and the pneumatic loss of air-out air current is littleer promptly to air supply efficiency is higher. In practical application, the second air deflector 30 is located below the front volute tongue 13, so that the concave arc surface of the second air deflector 30 faces the lower part of the air outlet 11, and thus the air flow can be directed downwards, and can be more easily diffused to the active area of a user, and user experience is improved.
The utility model discloses the air-conditioning indoor unit sets up the first aviation baffle 20 that is close to back spiral case 12 as the straight plate, makes first aviation baffle 20 lengthen the air-out route that flows along the wall of back spiral case 12 chamber, improves the air supply distance; the second air deflector 30 is set to be an arc plate, the concave arc surface of the second air deflector 30 faces to the side far away from the front volute tongue 13, so that the second air deflector 30 can guide the air outlet airflow downwards, meanwhile, the second air deflector 30 arranged in an arc surface can enable the air flow steering process to be smoother, the pneumatic loss is reduced, and the air outlet quantity can be effectively improved.
As shown in fig. 1 and 2, the long side of the first air deflector 20 is adjacent to the edge of the rear scroll 12. In the embodiment, the long side of the first air guiding plate 20 is connected to the edge of the air outlet end of the rear volute 12 on the air outlet path, so as to reduce the distance between the first air guiding plate 20 and the edge of the rear volute 12, thereby reducing the loss of the air flowing from the rear volute 12 to the first air guiding plate 20, and increasing the air outlet amount flowing along the first air guiding plate 20. Specifically, the first air deflector 20 is rotatably disposed at the air outlet 11, and a rotation axis of the first air deflector 20 is adjacent to an edge of the rear scroll 12. The rotation axis of the first air deflector 20 is adjacent to the side edge of the first air deflector 20 close to the edge of the rear volute 12, so that in the rotation process of the first air deflector 20, the joint of the long side edge of the first air deflector and the rear volute 12 does not generate obvious depression or protrusion, the influence on the air outlet flow in the rotation process of the first air deflector 20 is reduced, and the air supply efficiency is ensured. In practical applications, the distance between the rotation axis of the first air deflector 20 and the rear volute 12 is not more than 10 mm. If the distance between the rotation axis of the first air deflector 20 and the rear volute 12 exceeds 10mm, the long side of the first air deflector 20 is prone to upwarp or sag relative to the inner wall surface of the rear volute 12 during the rotation process, and therefore, the distance between the rotation axis of the first air deflector 20 and the rear volute 12 is set to be less than or equal to 10mm, so that the rear volute 12 and the first air deflector 20 can keep smooth transition, thereby ensuring that the air flow flows through the gap more stably and smoothly, and improving the air output.
As shown in fig. 2, the first wind deflector 20 has a wind guiding surface 21 and a leeward surface 22, and a side edge of the leeward surface 22 adjacent to the rear scroll 12 forms a clearance slope 221. In this embodiment, the wind guiding surface 21 is a surface facing the wind outlet flow, the leeward surface 22 is a surface facing away from the wind outlet flow, and the leeward surface 22 is adjacent to the side edge of the rear volute 12 to form a position avoiding inclined surface 221, so that the first wind guiding plate 20 can avoid interfering with the edge of the rear volute 12 during the rotation process, thereby improving the stability of the first wind guiding plate 20 during the rotation process. Specifically, a third air guiding inclined surface 211 is formed on a side of the air guiding surface 21 away from the rear volute 12. The outlet air flowing along the guide surface leaves the first air deflector 20 after passing through the third guide inclined surface 211, and the third guide inclined surface 211 enables the outlet air to leave the first air deflector 20 more naturally and softly, so that the air volume loss caused by sudden change of the air flow is prevented, and the outlet air effect is improved. In practical application, the inclination angles of the avoiding inclined plane 221 and the third guiding inclined plane 211 relative to the air guiding plane 21 can be set to be 15-25 degrees, so that the processing process is simplified on the basis of exerting the avoiding and guiding functions.
The central angle of the second air deflector 30 is not less than 15 degrees and not more than 25 degrees. In this embodiment, if the central angle of the second air guiding plate 30 is smaller than 15 °, a contact included angle between the outlet airflow and the second air guiding plate 30 may be caused, which is likely to cause the outlet airflow to lose a large amount of air during the turning process; if the central angle of the second air deflector 30 is greater than 25 °, the turning influence on the outlet air flow is small, and the air flow is not easy to be guided to the required direction; therefore, the central angle of the second air deflector 30 is set to 15-25 degrees, and can be selected to be 20 degrees, so that the air flow can be effectively guided, and the air loss in the air flow steering process can be reduced.
As shown in fig. 2, a first diversion inclined plane 31 is formed at the inner end of the concave arc surface of the second air deflector 30. In this embodiment, the inner end of the concave arc surface of the second air guiding plate 30 is close to the end of the air outlet 11, and the first guiding inclined surface 31 is formed at the inner end of the concave arc surface of the second air guiding plate 30, so that the flowing process of the air flow when contacting the second air guiding plate 30 is softer and more natural, the air flow is prevented from sudden change or disorder due to contacting the second air guiding plate 30, and the stability of the air flow is further improved. Specifically, the outer end of the convex arc surface of the second air deflector 30 forms a second air guiding inclined surface 32. The outer end of the convex arc surface of the second guide plate is away from one end of the air outlet 11, and a second guide inclined plane 32 is formed at the outer end of the convex arc surface of the second air deflector 30, so that the air flow is more natural and soft when leaving the convex arc surface of the second air deflector 30, and the loss of the wind wheel is further reduced.
In practical application, the inclination angles of the first diversion inclined surface 31 and the second diversion inclined surface 32 can be set to be 15-20 degrees, so that the processing difficulty is reduced on the basis of exerting the diversion function. It can be understood that the inclination angle of the first guiding inclined plane 31 is an included angle formed between the first guiding inclined plane 31 and a tangent line passing through the inner end of the second air guiding plate 30, and the inclination angle of the second guiding inclined plane 32 is an included angle formed between the second guiding inclined plane 32 and a tangent line passing through the outer end of the second air guiding plate 30.
As shown in fig. 2, the second wind deflector 30 has a rotation axis 33, and the rotation axis 33 is located between the second wind deflector 30 and the front volute tongue 13. In this embodiment, the second air guiding plate 30 can rotate around the rotation axis 33 to adjust the direction of the outlet air flow. The rotation axis 33 is located outside the second air guiding plate 30, so that the rotation axis 33 only needs to rotate by a small amplitude to rotate the second air guiding plate 30 in place, thereby improving the driving efficiency of the second air guiding plate 30. The rotation axis 33 is located between the convex arc surface of the second air deflector 30 and the front volute tongue 13, and can hide and protect the driving structure of the second air deflector 30, so as to improve the stability of the second air deflector 30 in the moving process.
Specifically, the distance between the rotation axis 33 and the second air deflector 30 is not less than 10mm and does not exceed 15mm, and it can be understood that the distance between the rotation axis 33 and the second air deflector 30 is the minimum distance that can be reached, and the distance is set to 10mm to 15mm, which can improve the driving efficiency of the second air deflector 30 and reduce the occupied space of the driving structure in the casing 10, so that the internal structure of the air conditioning indoor unit is simpler and more compact.
As shown in fig. 3, the second air guiding plate 30 rotates to a closing position for closing the air outlet 11 together with the first air guiding plate 20. In the embodiment, the first air deflector 20 and the second air deflector 30 are both rotatably mounted at the air outlet 11, and the first air deflector 20 and the second air deflector 30 can be rotated to close the air outlet 11 together, so as to close the air outlet 11 in the shutdown state of the air conditioning indoor unit, thereby maintaining the integrity of the appearance of the air conditioning indoor unit. Specifically, when the second air deflector 30 is located at the closed position, the concave arc surface faces outward, so that the second air deflector 30 is recessed relative to the air outlet 11 in the shutdown state of the air-conditioning indoor unit, damage caused by collision is prevented, and the second air deflector can be rotated to the position where the concave arc surface faces downward more quickly and easily when the air-conditioning indoor unit is started.
In combination with the above embodiments of the third guiding inclined surface 211 and the first guiding inclined surface 31, when the first air guiding plate 20 and the second air guiding plate 30 close the air outlet 11, the air guiding surface 21 of the first air guiding plate 20 faces inward, the concave arc surface of the second air guiding plate 30 faces outward, and at this time, the third guiding inclined surface 211 is overlapped with the first guiding inclined surface 31 to avoid the first air guiding plate 20 and the second air guiding plate 30 from interfering with each other, so that the first air guiding plate 20 and the second air guiding plate 30 can be in smooth transition, and the integrity of the air conditioner indoor unit in the shutdown state is further improved.
Specifically, the width ratio of the first air deflector 20 to the air outlet 11 is not less than 40% and does not exceed 45%; the width ratio of the second air deflector 30 to the air outlet 11 is not less than 55% and does not exceed 60%, so that the first air deflector 20 and the second air deflector 30 can be matched with each other to close the air outlet 11 together, and the guiding effects of prolonging the air supply distance and adjusting the air outlet flow direction can be improved.
