背景技术Background technique
贯流风机运行时，随着贯流风机的转速的变化，贯流风机包括稳定的工作区间和不稳定的工作区间。在稳定的工作区间内，送风风道的出风量与贯流风机的转速为线性关系。随着贯流风机的转速降低，贯流风机进入不稳定的工作区间，送风风道的出风量会非线性地急剧下降。这时空调器出现不连续的喘息现象，也可能会发生倒吸风。When the cross-flow fan is running, as the rotation speed of the cross-flow fan changes, the cross-flow fan includes a stable working area and an unstable working area. Within a stable working range, the air output of the air supply duct has a linear relationship with the speed of the cross-flow fan. As the speed of the cross-flow fan decreases, the cross-flow fan enters an unstable working range, and the air output of the air supply duct will decrease sharply and non-linearly. At this time, the air conditioner will appear discontinuous wheezing, and draft may also occur.
为了满足人们对空调器不同出风量的需求，贯流风机会在低速下运行，这时，空调器的噪音会比较大。随着人们生活水平的提升，在某些情况下，比如睡眠或者学习，人们对于空调器的噪声提出了更高的要求。为了满足空调器不同的使用场景，这就需要降低空调器在低出风量下的噪音。In order to meet people's needs for different air output volumes of air conditioners, cross-flow fans will run at low speeds. At this time, the noise of the air conditioners will be relatively loud. With the improvement of people's living standards, in some cases, such as sleeping or studying, people have put forward higher requirements for the noise of air conditioners. In order to meet the different usage scenarios of the air conditioner, it is necessary to reduce the noise of the air conditioner under low air output.

如图4至图6所示，在仿真图中，送风风道310内的浅灰区表示气流比较均匀，送风风道310内的黑色区域表示喘息区，也即回流区。贯流风机200的转速降低时，送风风道310内会出现回流区，回流区会导致空调器室内机10产生噪音。如图4所示，贯流风机200的转速较高，这时送风风道310 内大部分区域的气流比较均匀，回流区较小。如图5所示，贯流风机200的转速中等，送风风道310内的回流区的面积有所增加。如图6所示，贯流风机200低转速运行，送风风道310内的回流区的面积进一步增加。发明人发现，随着贯流风机200的转速降低，送风风道310内的回流区的面积逐步增加，这会导致空调器室内机10的噪声越来越大。As shown in Figures 4 to 6, in the simulation diagrams, the light gray area in the air supply duct 310 represents a relatively uniform air flow, and the black area in the air supply duct 310 represents a breathing area, that is, a backflow area. When the rotational speed of the cross-flow fan 200 decreases, a backflow area will appear in the air supply duct 310, and the backflow area will cause the air conditioner indoor unit 10 to generate noise. As shown in FIG. 4 , when the cross-flow fan 200 rotates at a high speed, the air flow in most areas of the supply air duct 310 is relatively uniform and the return flow area is small. As shown in FIG. 5 , the rotation speed of the cross-flow fan 200 is medium, and the area of the return flow area in the air supply duct 310 increases. As shown in FIG. 6 , the cross-flow fan 200 operates at low speed, and the area of the return flow area in the air supply duct 310 further increases. The inventor found that as the rotation speed of the cross-flow fan 200 decreases, the area of the return flow area in the air supply duct 310 gradually increases, which causes the noise of the indoor unit 10 of the air conditioner to become louder and louder.
如图1至图3所示，本发明实施例提供一种空调器室内机10，该空调器室内机10包括贯流风机200和送风蜗壳300，其中，送风蜗壳300包括风机段320和风道段330。送风蜗壳300从贯流风机200的外周向空调器室内机10的送风口100延伸设置，并限定出送风风道310。风机段320沿贯流风机200的外周朝向送风口100延伸。风道段330的第一侧枢转地设置于风机段320的延伸端321，其第二侧朝向送风口100延伸，配置为在朝向和背向送风风道310之间转动，以改变送风风道310的宽度。As shown in Figures 1 to 3, an embodiment of the present invention provides an air conditioner indoor unit 10.

The air supply volute 300 extends from the outer periphery of the cross-flow fan 200 toward the air supply port 100 of the air conditioner indoor unit 10 and defines an air supply duct 310 . The fan section 320 extends along the outer periphery of the cross-flow fan 200 toward the air supply opening 100 .

The volute tongue 390 and the fan section 320 are spaced apart along the outer circumference of the cross-flow fan 200, so that a part of the blades of the cross-flow fan 200 is located outside the air supply duct 310, and the other part of the blades of the cross-flow fan 200 is located in the air supply duct. 310 inside. The airflow enters the interior of the cross-flow fan 200 from a part of the blade cascades, passes through the cross-flow fan 200, and is discharged into the air supply duct 310 from another part of the blade cascades.
如图2和图3所示，风机段320沿贯流风机200的外周朝向送风口100延伸；也即，风机段320是沿着贯流风机200的外周设置的，并且，风机段320在沿着贯流风机200的外周设置的同时，其一端是朝向送风口100的，称之为延伸端321。或者理解为，风机段320的形状为弧状，设置于贯流风机200的外侧，包围贯流风机200。在本实施例中，风机段320的曲率和大小不做具体限定，也即风机段320包围贯流风机200的面积不做限定，风机段320与贯流风机200之间的间距不做限定，可根据需要选择。例如，间距可以是渐变的。As shown in FIGS. 2 and 3 , the fan section 320 extends along the outer periphery of the cross-flow fan 200 toward the air supply opening 100 ; that is, the fan section 320 is disposed along the outer periphery of the cross-flow fan 200 , and the fan section 320 extends along the outer periphery of the cross-flow fan 200 . While being disposed along the outer periphery of the cross-flow fan 200, one end thereof faces the air supply port 100, which is called the extension end 321. Or it can be understood that the fan section 320 is in an arc shape and is arranged outside the cross-flow fan 200 to surround the cross-flow fan 200 . In this embodiment, the curvature and size of the fan section 320 are not specifically limited, that is, the area of the fan section 320 surrounding the cross-flow fan 200 is not limited, and the distance between the fan section 320 and the cross-flow fan 200 is not limited. You can choose according to your needs. For example, the spacing can be gradient.
沿着送风风道310内气体的流向，风道段330位于风机段320的下游，也即风道段330更靠近送风口100。风道段330的曲率小于风机段320的曲率，也即，风机段320的弯曲程度比风道段330的弯曲程度大。风道段330的第一侧枢转地设置于风机段320的延伸端321，这使得风道段330在转动以改变送风风道310的宽度时，使得送风风道310内壁比较连续和光滑，使得送风风道310出风比较流畅。风道段330的第一侧和风道段330的第二侧相对设置，风道段330的第一侧位于送风风道310内气流的上游，风道段330的第二侧位于送风风道310内气流的下游。或者理解为，风道段330的第一侧远离送风口100，靠近风机段320的延伸端321，风道段330的第二侧靠近送风口100。风道段330配置为在朝向和背向送风风道310之间转动，也即，风道段330配置为在朝向和背向蜗壳之间转动，以改变送风风道310的宽度。在本实施例中，风道段330可转动的角度范围不做限定，可根据具体机型以及具体需要设置，风道段330能转动以改变送风风道310的宽度即可。Along the flow direction of the air in the air supply duct 310 , the air duct section 330 is located downstream of the fan section 320 , that is, the air duct section 330 is closer to the air supply outlet 100 . The curvature of the air duct section 330 is smaller than the curvature of the fan section 320 , that is, the fan section 320 has a greater curvature than the air duct section 330 . The first side of the air duct section 330 is pivotally disposed at the extended end 321 of the fan section 320, which allows the air duct section 330 to rotate to change the width of the air supply air duct 310, making the inner wall of the air supply air duct 310 more continuous and smooth. Smooth, making the air outlet from the air supply duct 310 smoother. The first side of the air duct section 330 and the second side of the air duct section 330 are arranged oppositely. The first side of the air duct section 330 is located upstream of the air flow in the air supply duct 310 , and the second side of the air duct section 330 is located in the air supply airflow. Downstream of the air flow in channel 310. Or it can be understood that the first side of the air duct section 330 is away from the air supply outlet 100 and is close to the extended end 321 of the fan section 320 , and the second side of the air duct section 330 is close to the air supply outlet 100 . The air duct section 330 is configured to rotate between facing and facing away from the air supply air duct 310 , that is, the air duct section 330 is configured to rotate between facing and facing away from the volute to change the width of the air supply air duct 310 . In this embodiment, the rotatable angle range of the air duct section 330 is not limited and can be set according to the specific machine model and specific needs. The air duct section 330 can be rotated to change the width of the air supply duct 310 .
如图4至图6所示，贯流风机200的转速降低时，送风风道310内的风量会下降，送风风道310内会出现回流区。而且，贯流风机200的转速越低， 送风风道310内的回流区越大。在本实施例中，风道段330被配置为在贯流风机200的风速降低的情况下，朝向送风风道310转动以使送风风道310的宽度变小。如图7所示，这能强制地删除送风风道310内的回流区，避免空调器室内机10产生噪音。As shown in FIGS. 4 to 6 , when the rotation speed of the cross-flow fan 200 decreases, the air volume in the air supply duct 310 will decrease, and a backflow area will appear in the air supply duct 310 . Moreover, the lower the rotational speed of the cross-flow fan 200 is, the larger the return flow area in the air supply duct 310 is. In this embodiment, the air duct section 330 is configured to rotate toward the air supply duct 310 to reduce the width of the air supply duct 310 when the wind speed of the cross-flow fan 200 decreases. As shown in FIG. 7 , this can forcibly delete the return flow area in the air supply duct 310 to prevent the indoor unit 10 of the air conditioner from generating noise.
基于上述分析，风道段330能朝向和背向送风风道310转动，以改变送风风道310的宽度。贯流风机200的转速降低时，风道段330朝向送风风道310转动，以使送风风道310的宽度下降。这能强制地删除送风风道310内的回流区，避免空调器室内机10产生噪音。Based on the above analysis, the air duct section 330 can rotate toward and away from the air supply duct 310 to change the width of the air supply duct 310 . When the rotational speed of the cross-flow fan 200 decreases, the air duct section 330 rotates toward the air supply duct 310 so that the width of the air supply duct 310 decreases. This can forcibly delete the return flow area in the air supply duct 310 to prevent the indoor unit 10 of the air conditioner from generating noise.
在其它一些实施例中，送风蜗壳300还包括固定段340，固定段340设置于送风口100处，在风道段330背向送风风道310转动至使送风风道310最宽的第一位置时，与风道段330的第二侧相接。一般情况下，如图2和图3所示，固定段340从送风口100逐渐朝向风道内倾斜设置，若固定段340和风道段330一起转动，在转动至和第一摆叶400抵触形成较窄的送风风道310时，容易使得较窄的送风风道310内壁不连续。其次，若风道段330直接抵触送风口100处，人们很容易观察到风道段330和送风口100抵触，影响美观。In some other embodiments, the air supply volute 300 also includes a fixed section 340. The fixed section 340 is disposed at the air supply opening 100. The air duct section 330 rotates away from the air supply duct 310 to make the air supply duct 310 the widest. When in the first position, it is connected with the second side of the air duct section 330 . Generally, as shown in FIGS. 2 and 3 , the fixed section 340 is gradually inclined from the air supply opening 100 toward the air duct. If the fixed section 340 and the air duct section 330 rotate together, they will rotate until they conflict with the first swing blade 400 to form a relatively large gap. When the air supply duct 310 is narrow, it is easy to make the inner wall of the narrow air supply duct 310 discontinuous. Secondly, if the air duct section 330 directly collides with the air supply outlet 100, people can easily observe that the air duct section 330 conflicts with the air supply outlet 100, which affects the appearance.
在其它一些实施例中，固定段340与风道段330的第二侧相接时，风机段320、风道段330与固定段340形成完整连续的第一风道壁370。也即，风机段320、风道段330与固定段340形成完整连续的第一风道壁370内壁，也即风机段320的内壁、风道段330的内壁与固定段340的内壁不存在凹凸不平，相接处不存在缝隙和不平整等。这可以使得气体在送风风道310内顺畅流动，避免吹哨，降低噪声。In some other embodiments, when the fixed section 340 is connected to the second side of the air duct section 330, the fan section 320, the air duct section 330 and the fixed section 340 form a complete and continuous first air duct wall 370. That is to say, the fan section 320, the air duct section 330 and the fixed section 340 form a complete and continuous inner wall of the first air duct wall 370, that is, there is no unevenness in the inner wall of the fan section 320, the inner wall of the air duct section 330 and the inner wall of the fixed section 340. Uneven, there are no gaps or unevenness at the joints. This can allow gas to flow smoothly in the air supply duct 310, avoid whistling, and reduce noise.

The overlapping portion 360 is provided on the stroke portion 350. When the air duct section 330 rotates toward the air supply duct 310 to the narrowest second position of the air supply duct 310, it overlaps the fixing section 340 to fix the air duct section 330.
在本实施例中，行程部350的具体结构和形状不做限定，可根据需要选择。作为一个具体的实施方式，如图2和图3所示，行程部350的形状为板状。很显然，这仅为示例性的，并不是唯一的。例如，行程部350的形状可以是长条状的支撑杆等。行程部350背向送风风道310伸出，也即，行程部350背向风道段330的内侧伸出。In this embodiment, the specific structure and shape of the stroke portion 350 are not limited and can be selected as needed.

在其它一些实施例中，空调器室内机10还包括多个第二摆叶500，多个第二摆叶500分别沿送风口100的长度方向枢转地设置于送风口100处，配置为受控地独立转动至预设位置以使送风风道310的气流均匀。In some other embodiments, the air conditioner indoor unit 10 further includes a plurality of second swing blades 500. The plurality of second swing blades 500 are respectively pivotally disposed at the air supply opening 100 along the length direction of the air supply opening 100 and are configured to receive The air supply duct 310 can be independently rotated to a preset position in a controlled manner to make the air flow in the air supply duct 310 uniform.

Obviously, this is only an example. , not the only one.
在其它一些实施例中，固定段340从送风口100逐渐朝向风道内倾斜延伸。也即，固定段340沿着送风风道310内气流的方向逐渐背向蜗舌390倾斜，这使得送风口100的宽度比较大，送风范围比较广。In some other embodiments, the fixed section 340 gradually extends obliquely from the air supply opening 100 toward the air duct. That is, the fixed section 340 gradually tilts away from the volute tongue 390 along the direction of the air flow in the air supply duct 310, which makes the width of the air supply opening 100 relatively large and the air supply range relatively wide.

In this embodiment, when the air duct section 330 rotates from the first position to the second position, the angle range through which the air duct section 330 rotates is not specifically limited and can be selected as needed. Specifically, as shown in Figure 3, the rotation angle of the air duct section 330 is 22°. This can not only eliminate the return flow area and reduce the noise of the air conditioner indoor unit 10, but also does not affect the air supply volume.
搭接部360伸出的长度值是风道段330壁厚值的1倍至6倍。具体地，如图2和图3所示，搭接部360伸出的长度值是风道段330壁厚值的3倍。这既能固定风道段330，也能保证送风蜗壳300的强度。The extended length of the overlapping portion 360 is 1 to 6 times the wall thickness of the air duct section 330 . Specifically, as shown in FIGS. 2 and 3 , the extended length of the overlapping portion 360 is three times the wall thickness of the air duct section 330 . This can not only fix the air duct section 330, but also ensure the strength of the air supply volute 300.
在其它一些实施方式中，贯流风机200的转速降低时，风道段330朝向送风风道310转动以使送风风道310变窄。贯流风机200的转速降低时，容易出现回流区，风道变窄可以强制删除回流区，避免产生噪音。In some other embodiments, when the rotational speed of the cross-flow fan 200 decreases, the air duct section 330 rotates toward the air supply duct 310 to narrow the air supply duct 310 . When the speed of the cross-flow fan 200 is reduced, a backflow area is likely to occur. The narrowing of the air duct can forcibly delete the backflow area to avoid noise.

When the air duct section 330 rotates to the first position, the second side of the air duct section 330 is connected to the fixed section 340. In this embodiment, the specific length of the air duct section 330 along the airflow direction in the air supply duct 310 is not limited. According to the specific machine model, it is sufficient that the air duct section 330 does not extend out of the air supply opening 100 during rotation. , that is, the air duct section 330 is always located in the air supply outlet 100 during the rotation. As a specific embodiment, as shown in Figures 2 and 3, the length of the air duct section 330 is 3/4 of the sum of the length of the air duct section 330 and the length of the fixed section 340, and the length of the air duct section 330 is the length of the first air duct. 1/3 of the total length of wall 370.
