本发明的壁挂式空调室内机中，第一送风口朝前敞开，第二送风口朝下敞开，使空调整体送风角度范围更大。第一送风口外侧设置有分流件，可引导出风气流朝分流件的边缘发散地吹向室内环境，使出风气流更加分散，扩散范围更大，从而使得室内制冷/制热速度更快，室内各处温度变化更加均匀，温差更小。出风气流分散吹出后不会强吹人体，也更加接近于自然风，使人感更加舒适。而且，第二送风口设置有多个独立受控的导风板，以便通过调节各导风板的开闭，来调节两个送风口的风量占比。In the wall-mounted air conditioner indoor unit of the present invention, the first air supply port is opened forward, and the second air supply port is opened downward, so that the overall air supply angle range of the air conditioner is larger. A splitter is arranged on the outside of the first air supply port, which can guide the outlet air flow to blow toward the indoor environment divergently towards the edge of the splitter, so that the outlet air flow is more dispersed and the diffusion range is larger, so that the indoor cooling/heating speed is faster.

本发明实施例提供了一种壁挂式空调室内机。壁挂式空调室内机为分体壁挂式房间空调器的室内部分，用于调节室内空气，例如制冷/制热、除湿、引入新风等等。An embodiment of the present invention provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is the indoor part of the split wall-mounted room air conditioner, and is used to adjust indoor air, such as cooling/heating, dehumidification, and introducing fresh air, etc.

如图1至图3所示，本发明实施例的壁挂式空调室内机一般性地可包括机壳10、分流件30和多个导风板61、62。As shown in FIGS. 1 to 3 , the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 , a flow divider 30 and a plurality of air deflectors 61 , 62 .
机壳10开设有朝前的第一送风口11和朝下的第二送风口12。机壳10用于挂在室内墙壁上。如图1，机壳10可为沿水平方向延伸的长条状，横截面大致为四边形。机壳10可包括顶壁、前壁、后壁和底壁和横向两个端壁，其后壁贴靠挂在室内墙壁上。第一送风口11可开设于机壳10的前壁底部，第二送风口12可开设于机壳10的底壁前部。机壳10的横向或者称为长度方向在图中用x表示。The casing 10 is provided with a first air outlet 11 facing forward and a second air outlet 12 facing downward. The casing 10 is used to hang on the indoor wall. As shown in FIG. 1 , the casing 10 may be in the shape of a strip extending along the horizontal direction, and the cross section is substantially quadrilateral. The casing 10 may include a top wall, a front wall, a rear wall, a bottom wall and two lateral end walls, the rear wall of which is attached to and hung on the indoor wall. The first air outlet 11 can be opened at the bottom of the front wall of the cabinet 10 , and the second air outlet 12 can be opened at the front of the bottom wall of the cabinet 10 . The transverse or longitudinal direction of the housing 10 is indicated by x in the figure.
第一送风口11和第二送风口12用于将机壳10内的气流吹向室内，调节室内空气。前述的气流可为壁挂式空调室内机在制冷模式下制取的冷风，在制热模式下制取的热风，或者在新风模式下引入的新风等。The first air supply port 11 and the second air supply port 12 are used to blow the airflow in the casing 10 to the room to adjust the indoor air. The aforementioned airflow can be cold air produced by the indoor unit of the wall-mounted air conditioner in cooling mode, hot air produced in heating mode, or fresh air introduced in fresh air mode.
壁挂式空调室内机可为通过蒸气压缩制冷循环***进行制冷/制热的空调器的室内机，其还包括换热器40和贯流风机50。换热器40设置在机壳10内，用于与流经其的气流进行换热，形成热交换气流，即冷风或热风，其可为三段式翅片换热器。贯流风机50设置于机壳10内，用于促使室内空气经机壳10顶部进风口13进入机壳10，使其与换热器40完成换热成为热交换气流，然后促使热交换气流经风道20流动至第一送风口11和第二送风口12，最终从第一送风口11和第二送风口12吹向室内。The wall-mounted air conditioner indoor unit may be an indoor unit of an air conditioner that performs refrigeration/heating through a vapor compression refrigeration cycle system, and it also includes a heat exchanger 40 and a cross-flow fan 50 . The heat exchanger 40 is arranged in the casing 10 for exchanging heat with the air flow passing through it to form a heat exchange air flow, namely cold air or hot air, which can be a three-stage fin heat exchanger. The cross-flow fan 50 is arranged in the casing 10, and is used to force the indoor air to enter the casing 10 through the air inlet 13 on the top of the casing 10, so that it can complete heat exchange with the heat exchanger 40 and become a heat exchange air flow, and then promote the heat exchange air to pass through the casing 10. The air duct 20 flows to the first air supply port 11 and the second air supply port 12 , and finally blows into the room from the first air supply port 11 and the second air supply port 12 .
分流件30与第一送风口11间隔地设置在第一送风口11前侧，以使第一送风口11的出风气流吹向分流件30，然后在分流件30的后表面引导下朝分流件30的边缘发散地吹向室内环境。The splitter 30 is spaced apart from the first air outlet 11 on the front side of the first air outlet 11, so that the air flow from the first air outlet 11 is blown to the splitter 30, and then guided by the rear surface of the splitter 30 toward the splitter. The edge of the piece 30 blows divergently towards the room environment.
导风板61、62的数量为多个，例如2个、3个或更多个，其沿前后方向并排设置在第二送风口12处。导风板61、62的作用对第二送风口12的出风气流的方向进行引导，以及用于开闭第二送风口12。There are multiple air deflectors 61 , 62 , such as 2, 3 or more, which are arranged side by side at the second air outlet 12 along the front and rear directions. The function of the air deflectors 61 and 62 is to guide the direction of the air flow from the second air supply port 12 and to open and close the second air supply port 12 .
本发明实施例中，如图3，出风气流从第一送风口11流出后，并非直接吹向室内环境，而是吹向分流件30，在分流件30的后表面引导下朝分流件30的边缘发散地吹向室内环境，能够使出风气流更加分散，扩散范围更大，使得室内制冷/制热速度更快，室内各处温度变化更加均匀，温差更小。出风气流分散吹出后不会强吹人体，也更加接近于自然风，使人感更加舒适。In the embodiment of the present invention, as shown in FIG. 3 , after the outlet air flow flows out from the first air supply port 11, it is not directly blown to the indoor environment, but blows to the splitter 30, and is directed toward the splitter 30 under the guidance of the rear surface of the splitter 30. The edge of the air blows divergently to the indoor environment, which can make the air flow more dispersed and the diffusion range larger, making the indoor cooling/heating faster, and the temperature changes in the room are more uniform and the temperature difference is smaller. After the air flow is scattered, it will not blow the human body forcefully, and it is closer to the natural wind, making people feel more comfortable.
现有的壁挂式空调室内机更多将改进方向放在如何更好地增大送风距离或加强对出风气流的方向引导，以使其吹到设定区域，使其达到躲避人体的目标。而本实施例创造性地改变思路，在出风气流刚刚吹出第一送风口11就使其向多个方向(至少2个方向)扩散，避免其出现向前直吹的强力气流，从而既能够躲避人体，又能够使冷量/热量扩散范围更大，减少室内温差。并且，本实施例利用分流件30取代了常规的导风板，并通过分流，使气流流速降低，避免因流速过快、未能对导风板及机壳10表面充分降温、使其温度分布不均而出现凝露。此外，可对分流件30进行表面处理，增加表面的疏水功能，进一步防止其表面产生凝露。The existing wall-mounted air-conditioning indoor units focus more on how to better increase the air supply distance or strengthen the direction guidance of the airflow, so that it can blow to the set area and achieve the goal of avoiding the human body . However, this embodiment creatively changes the way of thinking, and spreads to multiple directions (at least 2 directions) just after the first air supply port 11 is blown out by the air outlet airflow, so as to avoid the strong airflow directly blowing forward, so as to avoid the The human body can also make the cooling/heat diffusion range larger and reduce the indoor temperature difference. Moreover, the present embodiment utilizes the flow diverter 30 to replace the conventional air deflector, and through the diversion, the flow velocity of the air flow is reduced, avoiding that the air deflector and the surface of the casing 10 cannot be sufficiently cooled to make the temperature distribution due to the excessive flow velocity. Condensation occurs due to unevenness. In addition, surface treatment can be performed on the flow diverter 30 to increase the hydrophobic function of the surface and further prevent condensation on the surface.
此外，由于设置了多个导风板61、62，本发明可利用部分导风板引导出 风气流下出风方向，然后将靠前的导风板转动至合适角度，使其将气流更好地导向分流件30，以利用分流件30更好地分流送风。而且，当更多的导风板被打开时，第二送风口12的出风量相对更大，第一送风口11的出风量相应变小。更多的导风板被关闭后，第二送风口12的出风量相对更小，使第一送风口11的出风量相应变大。因此，本发明可通过调节开闭导风板的数量来调节两个送风口的出风量占比。In addition, since a plurality of wind deflectors 61, 62 are provided, the present invention can use some wind deflectors to guide the air flow to the direction of the wind, and then turn the front wind deflector to an appropriate angle to make the air flow better. Guide the splitter 30, so that the splitter 30 can better split the air. Moreover, when more air deflectors are opened, the air output volume of the second air supply port 12 is relatively larger, and the air output volume of the first air supply port 11 is correspondingly reduced. After more air deflectors are closed, the air output volume of the second air supply port 12 is relatively smaller, so that the air output volume of the first air supply port 11 is correspondingly increased. Therefore, the present invention can adjust the proportion of the air output of the two air supply ports by adjusting the number of open and close air deflectors.
在图1至图3所示实施例中，第一送风口11和第二送风口12均为长度方向平行于机壳10长度方向x的长条状，分流件30为平行于机壳10的长度方向的杆状。每个导风板61、62的转动轴线平行于机壳10的长度方向。此时，出风气流将在分流件30表面的引导下，朝分流件30的宽度方向(y方向)的两侧，即上下两侧吹出，从上侧吹出的气流上扬流动，流向更高更远的空间；从下侧吹出的气流下沉流动，流向更低更近的空间，使送风范围扩大。In the embodiment shown in FIGS. 1 to 3 , the first air supply port 11 and the second air supply port 12 are long strips whose length direction is parallel to the longitudinal direction x of the casing 10 , and the splitter 30 is parallel to the casing 10 Rod-shaped in the lengthwise direction. The rotation axis of each wind deflector 61 , 62 is parallel to the length direction of the casing 10 . At this time, the outlet airflow will be guided by the surface of the flow divider 30, and will be blown toward both sides of the width direction (y direction) of the flow divider 30, that is, the upper and lower sides, and the airflow blown from the upper side will flow upward, and flow to a higher and higher direction. Far space; the airflow blown from the lower side sinks and flows to a lower and closer space, expanding the range of air supply.
当然，在一些替代性实施例中，也可使第一送风口为圆形、方形、圆角矩形等其它形状，使分流件为相应形状，使出风气流沿分流件的径向向外流动。还可使机壳开设有沿其长度方向排列的多个第一送风口和多个第二送风口，每个第一送风口独立设置分流件，每个第二送风口独立设置导风板，具体不再赘述。Of course, in some alternative embodiments, the first air supply port can also be made into other shapes such as circle, square, rounded rectangle, etc., and the splitter can be made into a corresponding shape, so that the outlet air flow can flow outward along the radial direction of the splitter. . The casing can also be provided with a plurality of first air supply ports and a plurality of second air supply ports arranged along its length direction, each first air supply port is independently provided with a flow divider, and each second air supply port is independently provided with an air deflector, No more details.
在一些实施例中，如图2和图3所示，可使分流件30至少朝向第一送风口11的表面为外凸弯曲面32，以利于将气流朝分流件30的边缘引导。具体地，假如分流件30朝向第一送风口11的表面为平面，出风气流垂直地吹向该表面后，将转向90°后，才能沿该表面向边缘扩散。而本实施例使该表面为外凸弯曲面，出风气流冲击到外凸弯曲面32后再沿外凸弯曲面32向边缘扩散，气流转向小于90°，在转向过程中，外凸弯曲面32的外凸形状使得方向转变地相对更加缓和、气流损失和噪音都更小。In some embodiments, as shown in FIG. 2 and FIG. 3 , at least the surface of the splitter 30 facing the first air outlet 11 may be a convex curved surface 32 , so as to guide the airflow toward the edge of the splitter 30 . Specifically, if the surface of the flow divider 30 facing the first air outlet 11 is a plane, after the air flow blows vertically to the surface, it will turn 90° before spreading along the surface to the edge. However, in this embodiment, the surface is a convex curved surface, and the air flow impacts on the convex curved surface 32 and then spreads along the convex curved surface 32 to the edge, and the airflow is turned to less than 90°. The convex shape of 32 results in relatively smoother directional changes, less air loss and less noise.
如图2和图3所示，可使分流件30朝向第一送风口11和背向第一送风口11的两侧表面(即后表面和前表面)均为外凸弯曲面，分别为外凸弯曲面32和外凸弯曲面31，两者相接处构成两个顶端A1和A2，两个顶端A1和A2处可设置有圆角，使分流件30的横截面(垂直于x轴的截面)外形轮廓形成“橄榄形”。分流件30的这种结构较为简洁，易于制作，也使其外观更加美观。As shown in Fig. 2 and Fig. 3, the two side surfaces (that is, the rear surface and the front surface) of the splitter 30 facing the first air supply port 11 and facing away from the first air supply port 11 can be convex curved surfaces, respectively. Convex curved surface 32 and outwardly convex curved surface 31, two top ends A1 and A2 are formed at the junction of the two, and rounded corners can be provided at the two top ends A1 and A2, so that the cross section of the shunt 30 (perpendicular to the x-axis Section) profile forms an "olive shape". This kind of structure of the shunt 30 is relatively simple and easy to manufacture, and also makes its appearance more beautiful.
如图2和图3所示，更具体地，可使分流件30朝向第一送风口11的外凸弯曲面32由两段圆弧面CA1和CA2相接而成，以使外凸弯曲面32特别是其中间点C更加向外凸出，从而能够将吹向其的气流更均匀地向C点两侧分开。使背向第一送风口11的外凸弯曲面31为一段圆弧面，使其满足外观美观且便于制作即可。可进一步使外凸弯曲面32的两段圆弧面CA1、CA2的半径R1、R2和长度均相等，以使流向两者的气流趋于相等。当然，分流件30的横截面外形轮廓也可为椭圆形或其他不规则的形状，在此不再赘述。As shown in FIGS. 2 and 3 , more specifically, the convex curved surface 32 of the distributor 30 facing the first air supply port 11 can be formed by connecting two sections of arc surfaces CA1 and CA2, so that the convex curved surface 32, especially the middle point C is more protruding outward, so that the airflow blowing to it can be more evenly divided to both sides of point C. The convex curved surface 31 facing away from the first air supply port 11 can be a section of arc surface, so as to satisfy the aesthetic appearance and facilitate the manufacture. The radii R1, R2 and lengths of the two sections of arc surfaces CA1, CA2 of the convex curved surface 32 can be further made equal so that the airflows flowing towards them tend to be equal. Of course, the cross-sectional profile of the flow divider 30 may also be elliptical or other irregular shapes, which will not be repeated here.
在一些替代性实施例中，若第一送风口和分流件均为圆形，可使外凸弯曲面为球冠状，在此不再赘述。In some alternative embodiments, if both the first air supply port and the flow splitter are circular, the convex curved surface can be made into a spherical crown, which will not be repeated here.
在一些实施例中，如图2和图3，机壳10包括分隔条23、前后排列的蜗舌21、蜗壳22。分隔条23位于蜗舌21前端的下方，且位于蜗壳22下端的前方。分隔条23与蜗舌21和蜗壳22与共同限定出风道20。分隔条23与蜗舌21的前端限定出第一送风口11，分隔条23与蜗壳22的下端限定出第二送风口12。可以理解的是，蜗舌21、蜗壳22与分隔条23均为沿机壳长度方向延伸的长条状。风道20的进口处安装有长度方向平行于机壳10长度方向的贯流风机50。分隔条23为机壳10的一部分，可使之与相邻的机壳部分为一体成型结构。In some embodiments, as shown in FIG. 2 and FIG. 3 , the housing 10 includes a partition bar 23 , a volute tongue 21 and a volute case 22 arranged in front and rear. The partition bar 23 is located below the front end of the volute tongue 21 and in front of the lower end of the volute case 22 . The partition bar 23 together with the volute tongue 21 and the volute case 22 define the air passage 20 . The partition bar 23 and the front end of the volute tongue 21 define the first air supply port 11 , and the partition bar 23 and the lower end of the volute case 22 define the second air supply port 12 . It can be understood that the volute tongue 21 , the volute case 22 and the partition bar 23 are all elongated strips extending along the length direction of the casing. A cross-flow fan 50 whose length direction is parallel to the length direction of the casing 10 is installed at the inlet of the air duct 20 . The partition bar 23 is a part of the casing 10 and can be integrally formed with adjacent casing parts.
可使风道20具有与第一送风口11相接且过流截面沿气流方向逐渐变大的渐扩出口。即，风道20在邻近第一送风口11处为渐扩状，这种形状使气流在流出第一送风口11前已经开始向边缘扩散，更加利于出风气流的扩散吹出。The air duct 20 may have a gradually diverging outlet connected to the first air supply outlet 11 and having a flow cross section gradually increasing along the airflow direction. That is, the air duct 20 is in a gradually expanding shape adjacent to the first air supply port 11 , and this shape makes the air flow begin to diffuse toward the edge before flowing out of the first air supply port 11 , which is more conducive to the diffusion and blowing of the air flow.
具体地，蜗舌21从其进口端至出口端依次包括进风段(kc)、中间段(cs)和出风段(sa)。其中，进风段(kc)从进口端(k)向后下方延伸。中间段(cs)从进风段(kc)的末端(c)向前下方延伸。出风段(sa)从中间段(cs)的末端(s)向前上方延伸。蜗壳22位于蜗舌21后方，整体为凹侧朝前的弯曲形结构。分隔条23的上表面(ed段)从后向前逐渐向下倾斜延伸，以与出风段(sa)共同构成风道20的渐扩出口。可进一步使出风段(sa)和分隔条23的上表面(ed段)均为内凹的弧形，且各段均以圆角过渡，以使气流的方向转变更加平缓，减小流动损失。Specifically, the volute tongue 21 sequentially includes an air inlet section (kc), a middle section (cs) and an air outlet section (sa) from its inlet end to its outlet end. Wherein, the air inlet section (kc) extends backward and downward from the inlet end (k). The middle section (cs) extends forward and downward from the end (c) of the air inlet section (kc). The outlet section (sa) extends forward and upward from the end (s) of the middle section (cs). The volute 22 is located at the rear of the volute tongue 21 and is generally a curved structure with the concave side facing forward. The upper surface (section ed) of the partition bar 23 gradually extends downwards from the rear to the front, so as to form the gradually expanding outlet of the air duct 20 together with the air outlet section (sa). The air outlet section (sa) and the upper surface of the partition strip 23 (ed section) can be further made to be concave arcs, and each section is transitioned with rounded corners, so that the direction of the airflow can be changed more smoothly and the flow loss can be reduced .
在一些实施例中，如图2和图3所示，可使最靠前的导风板62在处于关闭状态时朝上的表面621为内凹弯曲状，以便导风板62处于打开状态时， 将气流引向分隔条23的下表面。其他导风板61可为平板状。如此一来，使得原本难以有气流通过的分隔条23下表面也有气流吹过，从而避免其在制冷模式下产生凝露。In some embodiments, as shown in FIG. 2 and FIG. 3 , the upwardly facing surface 621 of the most forward wind deflector 62 in the closed state can be concave and curved, so that when the wind deflector 62 is in the open state , directing the airflow to the lower surface of the partition bar 23 . Other wind deflectors 61 may be flat. In this way, airflow blows over the lower surface of the partition bar 23 which is difficult for airflow to pass through, thereby avoiding condensation in the cooling mode.
图4是图2所示壁挂式空调室内机在运行下吹模式时的示意图。Fig. 4 is a schematic diagram of the indoor unit of the wall-mounted air conditioner shown in Fig. 2 when operating in the down blowing mode.
在一些实施例中，可使分流件30配置成可动地安装于机壳10，以便调节其与第一送风口11的相对位置，从而能对出风气流风量、风向等参数进行调节。此处的“可动”包括平动、转动以及两者的结合等各种运动方式。分流件30越接近第一送风口11，第一送风口11的出风越受阻，其风量越小，但分流件30对出风气流的转向作用(促使气流朝其边缘方向转向)越强。当分流件30越远离第一送风口11，第一送风口11的出风越顺畅，风量越大，但对气流的转向作用变弱。In some embodiments, the flow divider 30 can be configured to be movably installed on the casing 10 so as to adjust its relative position to the first air supply port 11 , so as to adjust parameters such as air volume and direction of the air outlet. "Moveable" here includes translation, rotation, and a combination of the two. The closer the flow divider 30 is to the first air supply port 11, the more blocked the air outlet of the first air supply port 11 is, and the smaller the air volume is, but the stronger the diversion effect of the flow divider 30 on the outlet airflow (prompting the airflow to turn toward its edge direction). When the splitter 30 is farther away from the first air supply port 11 , the air flow from the first air supply port 11 is smoother and the air volume is greater, but the steering effect on the air flow becomes weaker.
更进一步地，分流件30配置成可沿前后方向平移且可围绕其上端或下端前后摆动，转动轴线平行于分流件30的长度方向。例如图3和图4所示，分流件30可前后平移且可绕其顶端前后摆动。当处于图3所示状态时，出风气流被分流件30分为上下两路吹出。在此基础上，将分流件30后移至关闭第一送风口11的状态，然后使其绕上端(A1端)向前摆动一定角度，到达图4的状态，使气流仅从分流件30表面向下流出。而且可以理解的是，分流件30摆动角度越大，其下端(A2端)离分隔条23越远，出风量越大。由此可见，本发明通过使分流件30能平移+摆动，使第一送风口11能够仅朝下送风、仅朝上送风且送风量均可调节。Furthermore, the flow divider 30 is configured to be able to translate along the front-rear direction and to swing back and forth around its upper end or lower end, and the rotation axis is parallel to the length direction of the flow divider 30 . For example, as shown in FIGS. 3 and 4 , the flow divider 30 can translate back and forth and swing back and forth around its top end. When in the state shown in FIG. 3 , the outlet airflow is divided into upper and lower paths by the splitter 30 and blown out. On this basis, move the flow divider 30 back to the state of closing the first air supply port 11, and then make it swing forward at a certain angle around the upper end (A1 end) to reach the state in Figure 4, so that the air flow only flows from the surface of the flow divider 30 Flow down. And it can be understood that, the larger the swing angle of the flow divider 30 is, the farther its lower end (A2 end) is from the partition bar 23, and the larger the air output is. It can be seen that the present invention enables the first air supply port 11 to only supply air downwards or upwards, and the air supply volume can be adjusted by enabling the splitter 30 to translate and swing.
分流件30配置成可运动至关闭第一送风口11的位置，如图3。还可使风道20渐扩出口处的表面轮廓与分流件30相应区段的表面轮廓相匹配，以使分流件30在关闭状态时贴合于风道20渐扩出口处的表面，这使得分流件30能更好地封闭第一送风口11，避免灰尘等异物经第一送风口11进入机壳10。并且，壁挂式空调室内机处于断电或者待机等非运行状态时，将分流件30移动至关闭状态，也使分流件30向内“嵌入”第一送风口11处，避免分流件30完全处于第一送风口11外影响美观。例如，当分流件30为橄榄形，其朝向第一送风口11的表面为外凸弯曲面32时，使出风段sa为内凹的弯曲面，以与之匹配。The splitter 30 is configured to be movable to the position of closing the first air outlet 11 , as shown in FIG. 3 . It is also possible to make the surface profile at the diverging outlet of the air duct 20 match the surface profile of the corresponding section of the flow divider 30, so that the divider 30 fits on the surface at the diverging outlet of the air duct 20 when it is in the closed state, which makes The splitter 30 can better seal the first air supply port 11 , preventing foreign matter such as dust from entering the casing 10 through the first air supply port 11 . Moreover, when the indoor unit of the wall-mounted air conditioner is in a non-operating state such as power-off or standby, the flow divider 30 is moved to the closed state, and the flow divider 30 is also "embedded" inward at the first air outlet 11, so as to avoid the flow divider 30 being completely in a state of being closed. The outside of the first air supply port 11 affects the appearance. For example, when the splitter 30 is olive-shaped and its surface facing the first air outlet 11 is an outwardly convex curved surface 32 , the outlet section sa is made to be a concave curved surface to match it.

When the air conditioner operates in cooling mode, it can supply air according to the air supply mode.
向下送风模式：如图4所示，控制分流件30关闭第一送风口11或小角度打开第一送风口11以向斜下方送风，使导风板61、62打开第二送风口12。在导风板61、62的引导下，由第二送风口12向下送风。在空调运行制热模式时，可以按照下送风模式送风，以利于加快制热速度。Downward air supply mode: as shown in Figure 4, control the splitter 30 to close the first air supply port 11 or open the first air supply port 11 at a small angle to supply air obliquely downward, so that the air deflectors 61, 62 open the second air supply port 12. Under the guidance of the air deflectors 61 and 62, the second air outlet 12 blows air downward. When the air conditioner is running in the heating mode, the air can be supplied according to the downward air supply mode, so as to accelerate the heating speed.
最大送风模式：如图5所示，使第一送风口11和第二送风口12均打开，两者同时出风，以使风量最大。Maximum air supply mode: as shown in FIG. 5 , both the first air supply port 11 and the second air supply port 12 are opened, and both of them output air at the same time to maximize the air volume.

The driving mechanism includes a rack 71 extending forward and backward and fixed to the distributor 30 , a gear 72 meshing with the rack 71 , and a motor 73 for driving the gear 72 to rotate to drive the rack 71 to translate forward and backward. The motor 73 can be fixed on the casing 10 , and the rack 71 can be slidably mounted on the casing 10 along the front and rear directions.
