可选地，立式空调室内机还包括：多个导叶，沿垂直于第一出气口所在平面的方向均匀间隔且呈辐射状设置于风道的渐缩部分的内侧面，以对流入环形出风间隙的气流在第一出气口的径向方向上进行梳理。Optionally, the vertical air conditioner indoor unit further includes: a plurality of guide vanes, evenly spaced along the direction perpendicular to the plane where the first air outlet is located, and radially arranged on the inner surface of the tapered part of the air duct to flow into the ring The air flow in the air outlet gap is combed in the radial direction of the first air outlet.
可选地，第一送风口位于第二送风口的上方；Optionally, the first air supply opening is located above the second air supply opening;
第一送风口是开设于壳体前侧上部的圆形口；第一出气口是开设于风道前侧上部的圆形口，且第一出气口的直径小于第一送风口的直径；第一出气口和第一送风口之间具有间隙，风道配置成在第一出气口的前端形成有环圈部，以遮蔽第一出气口和第一送风口的间隙并引导出风；The first air outlet is a circular opening opened on the upper part of the front side of the housing; the first air outlet is a circular opening opened on the upper part of the front side of the air duct, and the diameter of the first air outlet is smaller than the diameter of the first air outlet; There is a gap between an air outlet and the first air outlet, and the air duct is configured to form a ring portion at the front end of the first air outlet to shield the gap between the first air outlet and the first air outlet and guide the air out;

本发明的立式空调室内机中，风道临近其第一出气口处的内壁为渐缩状，使过流截面沿气流方向逐渐变小。并且，风道内部的导流件与风道内壁的渐缩部分限定出了一个环形出风间隙。如此一来，从进气口进入风道的气流(换热气流、新风气流等)流向第一出气口的过程中，将在导流件引导下将吹向风道内壁，最终流至环形出风间隙内。由于环形出风间隙的出风截面更小，使得其出风速度更高。高速气流在风道渐缩状内壁的引导下，在向外流动过程中逐渐向气流中心方向聚合，形成汇聚效应，使得风力更加强劲，送风距离更远，满足了立式空调室内机对远距离送风和强劲送风的需求。同时，本发明的立式空调室内机中，通过在前侧设置第一送风口和第二送风口，第一送风口为聚合送风口，第二送风口为普通送风口，可以进一步满足立式空调室内机对上下方向大面积送风的需求。In the vertical air conditioner indoor unit of the present invention, the inner wall of the air duct near the first air outlet is tapered, so that the flow cross section gradually becomes smaller along the airflow direction. In addition, the air guide inside the air duct and the tapered part of the inner wall of the air duct define an annular air outlet gap. In this way, when the airflow (heat exchange airflow, fresh airflow, etc.) entering the air duct from the air inlet flows to the first air outlet, it will blow towards the inner wall of the air duct under the guidance of the air guide, and finally flow to the annular outlet. Inside the wind gap. Since the air outlet section of the annular air outlet gap is smaller, the air outlet speed is higher. Under the guidance of the tapered inner wall of the air duct, the high-speed airflow gradually converges toward the center of the airflow during the outward flow process, forming a convergence effect, making the wind stronger and the air supply distance longer, which satisfies the distance of the vertical air conditioner indoor unit. Distance supply air and strong supply air demand. At the same time, in the vertical air conditioner indoor unit of the present invention, by providing a first air outlet and a second air outlet on the front side, the first air outlet is a polymer air outlet, and the second air outlet is an ordinary air outlet, which can further satisfy the requirements of vertical air outlets. The air conditioner indoor unit needs a large area of air supply in the up and down direction.
本发明的立式空调室内机中，导流件不仅与风道内壁限定出了环形出风间隙，达到提升风速的作用，同时也恰好能将气流导向环形出风间隙，或者说是强迫气流朝环形出风间隙流动，以迫使气流接受渐缩状内壁的聚合引导，形成最终的聚合出风效果。本发明仅通过改进风道形状和增设一导流件就实现了非常好的聚合送风效果，其结构非常简单，而且成本较低，易于实现量产推广，构思非常巧妙。In the vertical air conditioner indoor unit of the present invention, the deflector not only defines the annular air outlet gap with the inner wall of the air duct, so as to increase the wind speed, but also can guide the airflow to the annular air outlet gap, or force the airflow toward The annular air outlet gap flows to force the air flow to accept the polymerization guidance of the tapered inner wall to form the final polymerization air outlet effect. The invention realizes a very good aggregated air supply effect only by improving the shape of the air duct and adding a deflector, the structure is very simple, the cost is low, the mass production promotion is easy to realize, and the concept is very clever.
进一步地，本发明还对导流件的形状进行了特别设计，使得导流件由包括依次光滑相接的外凸的第一弧形段、内凹的第二弧形段、外凸的第三弧形段、外凸的第四弧形段和外凸的第五弧形段的导流线绕水平中心轴线旋转一周形成，使得气流流动过程中的流动阻力更小，能量损耗和噪声更小，同时汇聚效应更明显，提升了第一出气口的聚合送风效果。Furthermore, the present invention also specially designs the shape of the flow guide, so that the flow guide consists of a first arc-shaped section that is smoothly connected in sequence, a second arc-shaped section that is concave, and a second convex section. The guide lines of the three-arc section, the convex fourth arc section and the convex fifth arc section are formed by rotating around the horizontal central axis once, so that the flow resistance during the air flow is smaller, and the energy loss and noise are more At the same time, the convergence effect is more obvious, which improves the aggregate air supply effect of the first air outlet.
进一步地，本发明对风道形状进行特别设计，使风道的渐缩部分的内壁的流线形状与导流件相对部分的导流线的线型相同，能进一步减少出风阻力，提升出风强度，同时通过将进气口的位置低于第一出气口，使气流从下至上流向导流件，以便环形出风间隙底部区段的气流带动其余区段的气流共同朝前上方上扬流动。在制冷模式时，上扬流动的冷风可充分避开人体，达到最高点后再向下散落，实现一种“淋浴式”制冷体验，提高用户使用舒适性。并且，气流上扬吹出也有利于提升其送风距离。Furthermore, the present invention specially designs the shape of the air duct so that the streamline shape of the inner wall of the tapered part of the air duct is the same as the line shape of the diversion line of the opposite part of the deflector, which can further reduce the wind resistance and increase the Wind intensity, at the same time, by lowering the position of the air inlet to the first air outlet, the airflow flows from the bottom to the upflow guide, so that the airflow in the bottom section of the annular air outlet gap drives the airflow in the remaining sections to flow upward and forward together . In the cooling mode, the rising and flowing cold air can fully avoid the human body, and then fall down after reaching the highest point, realizing a "shower-like" cooling experience and improving user comfort. In addition, the upward blowing of the airflow is also conducive to increasing the air supply distance.

本发明实施例的立式空调室内机中，风道20临近其第一出气口21处的内壁为渐缩状，使过流截面沿气流方向逐渐变小。并且，风道20内部的导流件30与风道20内壁的渐缩部分150限定出了一个环形出风间隙15。如此一来，从进气口22进入风道20的气流(换热气流、新风气流等)流向第一出气口21的过程中，将在导流件30引导下将吹向风道20内壁，最终流至环形出风间隙15内。由于环形出风间隙15的出风截面更小，使得其出风速度更高。高速气流在风道20渐缩状内壁的引导下，在向外流动过程中逐渐向气流中心方向聚合，形成汇聚效应，使得风力更加强劲，送风距离更远，满足了立式空调室内机对远距离送风和强劲送风的需求。同时，本发明实施例的立式空调室内机中，通过在前侧设置第一送风口11和第二送风口13，第一送风口11为聚合送风口，第二送风口13为普通送风口，该立式空调室内机可以是仅经第一送风口11送风，也可以是仅经第二送风口13送风，还可以是经第一送风口11和第二送风口13送风。当两个送风口同时送风时，可以进一步满足立式空调室内机对上下方向大面积送风的需求。In the vertical air conditioner indoor unit of the embodiment of the present invention, the inner wall of the air duct 20 near the first air outlet 21 is tapered, so that the flow cross section gradually becomes smaller along the airflow direction. In addition, the air guide 30 inside the air duct 20 and the tapered portion 150 of the inner wall of the air duct 20 define an annular air outlet gap 15. In this way, when the air flow (heat exchange air flow, fresh air flow, etc.) entering the air duct 20 from the air inlet 22 flows to the first air outlet 21, it will blow toward the inner wall of the air duct 20 under the guidance of the air guide 30. Finally, it flows into the annular air outlet gap 15. Since the air outlet section of the annular air outlet gap 15 is smaller, the air outlet speed thereof is higher. Under the guidance of the tapered inner wall of the air duct 20, the high-speed airflow gradually converges toward the center of the airflow during the outward flow process, forming a convergence effect, making the wind stronger and the air supply distance longer, which satisfies the need for vertical air conditioning indoor units. The demand for long-distance air supply and strong air supply. At the same time, in the vertical air-conditioning indoor unit of the embodiment of the present invention, the first air supply port 11 and the second air supply port 13 are provided on the front side. The first air supply port 11 is a polymerization air supply port, and the second air supply port 13 is a normal air supply port. The vertical air conditioner indoor unit may be blown only through the first air outlet 11, may be blown only through the second air outlet 13, or may be blown through the first air outlet 11 and the second air outlet 13. When the two air outlets supply air at the same time, the vertical air conditioner indoor unit can further meet the demand for large area air supply in the vertical direction.
本发明实施例的立式空调室内机中，导流件30不仅与风道20内壁限定出了环形出风间隙15，达到提升风速的作用，同时也恰好能将气流导向环形出风间隙15，或者说是强迫气流朝环形出风间隙15流动，以迫使气流接受渐缩状内壁的聚合引导，形成最终的聚合出风效果。本发明仅通过改进风道20形状和增设一导流件30就实现了非常好的聚合送风效果，其结构非常简 单，而且成本较低，易于实现量产推广，构思非常巧妙。In the vertical air conditioner indoor unit of the embodiment of the present invention, the air guide 30 not only defines the annular air outlet gap 15 with the inner wall of the air duct 20 to achieve the effect of increasing the wind speed, but also can precisely guide the airflow to the annular air outlet gap 15. In other words, the airflow is forced to flow toward the annular air outlet gap 15, so as to force the airflow to accept the polymerization guidance of the tapered inner wall to form the final aggregated air outlet effect. The present invention achieves a very good aggregated air supply effect only by improving the shape of the air duct 20 and adding a deflector 30. The structure is very simple, and the cost is low, it is easy to realize mass production and promotion, and the concept is very clever.
参考图5，导流件30是由导流线绕水平中心轴线旋转一周形成，导流线包括依次光滑相接的外凸的第一弧形段(ab段)、内凹的第二弧形段(bc段)、外凸的第三弧形段(cd段)、外凸的第四弧形段(de段)和外凸的第五弧形段(ef段)，并且第一弧形段(ab段)、第二弧形段(bc段)、第三弧形段(cd段)在从后向前方向逐渐远离水平中心轴线，第五弧形段(ef段)的终点与第一弧形段(ab段)的起点同处于水平中心轴线上。在图1所示的实施例中，第一送风口11为圆形，第一出气口21为圆形，风道20的临近第一出气口21处的内壁纵截面也为圆形，环形出风间隙15也为圆环形出风间隙15。Referring to FIG. 5, the guide member 30 is formed by the guide wire rotating one round around the horizontal central axis, and the guide wire includes a convex first arc section (section ab) and a concave second arc that are smoothly connected in sequence. Section (bc section), convex third arc section (cd section), convex fourth arc section (de section) and convex fifth arc section (ef section), and the first arc Section (ab section), second arc section (bc section), and third arc section (cd section) gradually move away from the horizontal central axis from back to front. The end point of the fifth arc section (ef section) and the first The starting point of an arc segment (segment ab) is also on the horizontal central axis. In the embodiment shown in FIG. 1, the first air outlet 11 is circular, the first air outlet 21 is circular, and the longitudinal section of the inner wall of the air duct 20 adjacent to the first air outlet 21 is also circular, with a circular outlet The wind gap 15 is also an annular wind gap 15.
继续参考图2至图5，本发明实施例中，气流流动至导流件30时，先流经第一弧形段(ab段)，由于第一弧形段(ab段)为外凸设计，使得气流容易受导流件30引导。之后流经第二弧形段(bc段)，由于第二弧形段(bc段)为内凹设计，使气流流速加快，以远离第一出气口21的中心轴线地快速冲向风道20的内壁。第三弧形段(cd段)为外凸设计，以与风道20渐缩状内壁的走向更加接近，使得气流在被风道20的渐缩状内壁引导转而朝接近第一出气口21中心轴线转向过程中，受到第三弧形段(cd段)的阻力更小。第五弧形段(ef段)为外凸设计是作为导流件30的外端面将其设计成外凸形状可以使导流件30本身具有一定的将气流向前汇聚的效果。第四弧形段(de段)作为第三弧形段(cd段)和第五弧形段(ef段)的过渡区段，为外凸形状，以便气流从第三弧形段(cd段)光滑过渡至第五弧形段(ef段)。本发明实施例通过对导流件30的形状进行了特别设计，使得导流件30整体为对称的类圆锥形，由包括依次光滑相接的外凸的第一弧形段(ab段)、内凹的第二弧形段(bc段)、外凸的第三弧形段(cd段)、外凸的第四弧形段(de段)和外凸的第五弧形段(ef段)的导流线绕水平中心轴线旋转一周形成，使得气流流动过程中的流动阻力更小，能量损耗和噪声更小，同时汇聚效应更明显，提升了第一出气口21的聚合送风效果。Continuing to refer to Figures 2 to 5, in the embodiment of the present invention, when the airflow flows to the deflector 30, it first flows through the first arc section (section ab), because the first arc section (section ab) is a convex design , So that the airflow is easily guided by the deflector 30. After that, it flows through the second arc-shaped section (section bc). Because the second arc-shaped section (section bc) has a concave design, the airflow velocity is accelerated, and it quickly rushes toward the air duct 20 away from the central axis of the first air outlet 21 The inner wall. The third arc section (cd section) is a convex design, which is closer to the tapered inner wall of the air duct 20, so that the airflow is guided by the tapered inner wall of the air duct 20 to approach the first air outlet 21 During the turning process of the central axis, the resistance of the third arc section (cd section) is smaller. The fifth arc-shaped section (ef section) is designed to be convex as the outer end surface of the air guide 30. Designing it into an outer convex shape can make the air guide 30 itself have a certain effect of converging the air flow forward. The fourth arc section (de section) is used as the transition section of the third arc section (cd section) and the fifth arc section (ef section). ) Smooth transition to the fifth arc section (ef section). In the embodiment of the present invention, the shape of the flow guide 30 is specially designed, so that the flow guide 30 has a symmetrical conical shape as a whole, and is composed of a first arc-shaped section (a-b section) that is successively smoothly connected and convex. The concave second arc section (bc section), the convex third arc section (cd section), the convex fourth arc section (de section) and the convex fifth arc section (ef section) The guide wire of) is formed by rotating around the horizontal central axis once, so that the flow resistance during the air flow is smaller, the energy loss and the noise are smaller, and the convergence effect is more obvious, which improves the aggregate air supply effect of the first air outlet 21.
进一步地，本发明实施例通过对各弧形段的大小关系进行优化，以强化上述效果。在一些实施例中，第一弧形段(ab段)的半径小于第三弧形段(cd段)的半径，优选可使第一弧形段(ab段)与第三弧形段(cd段)的半径之比在0.4至0.6之间，例如半径之比为0.4、0.5、0.6。第二弧形段(bc段) 的半径大于第三弧形段(cd段)的半径，优选可使第二弧形段(bc段)与第三弧形段(cd段)的半径之比在2.2至2.7之间，例如半径之比为2.2、2.5、2.7。第四弧形段(de段)的半径小于等于第一弧形段(ab段)的半径，优选可使第四弧形段(de段)与第三弧形段(cd段)的半径之比在0.2至0.4之间，例如半径之比为0.2、0.3、0.4。第五弧形段(ef段)的半径大于第三弧形段(cd段)的半径，优选可使第五弧形段(ef段)与第三弧形段(cd段)的半径之比在1.8至3.0之间，例如半径之比为1.8、2.5、3.0。Further, the embodiment of the present invention optimizes the size relationship of each arc segment to enhance the above effect. In some embodiments, the radius of the first arc segment (segment ab) is smaller than the radius of the third arc segment (segment cd). Preferably, the first arc segment (segment ab) and the third arc segment (cd The ratio of the radii of the section) is between 0.4 and 0.6, for example, the ratio of the radii is 0.4, 0.5, 0.6. The radius of the second arc-shaped section (bc section) is greater than the radius of the third arc-shaped section (cd section), preferably the ratio of the radius of the second arc-shaped section (bc section) to the third arc-shaped section (cd section) Between 2.2 and 2.7, for example, the ratio of radii is 2.2, 2.5, 2.7. The radius of the fourth arc-shaped segment (de segment) is less than or equal to the radius of the first arc-shaped segment (ab segment), preferably the radius of the fourth arc-shaped segment (de segment) and the third arc-shaped segment (cd segment) The ratio is between 0.2 and 0.4, for example, the ratio of the radii is 0.2, 0.3, 0.4. The radius of the fifth arc section (ef section) is greater than the radius of the third arc section (cd section), preferably the ratio of the radius of the fifth arc section (ef section) to the third arc section (cd section) Between 1.8 and 3.0, for example, the ratio of radii is 1.8, 2.5, 3.0.
如图2所示，还可使导流件30的最宽处的宽度D1大于等于第一出气口21的宽度D2。发明人通过理论分析并经试验证实，D
1大于等于D2时可保证明显的气流汇聚效果，同时整个立式空调室内机的外形美观度高。
As shown in FIG. 2, the width D1 at the widest point of the air guide 30 may be greater than or equal to the width D2 of the first air outlet 21. By theoretical analysis, and the inventors confirmed through testing, D 1 be greater than or equal to ensure convergence effect significant air flow D2, while a high aesthetic appearance throughout the vertical air conditioning indoor unit.
继续参考图2、图3和图5，在一些实施例中，风道20的渐缩部分150的内壁的流线形状与导流件30相对部分的导流线的线型相同。图3中，以渐缩部分150的底部区段的流线为例，主要包括mn段和np段，其中mn段的线型与导流件30的第四弧形段(de段)的前部区段的线型相同，np段的线型与导流件30的第五弧形段(ef段)的后部区段的线型相同。参考图2和图3，进气口22的位置低于第一出气口21，以使气流从下至上流向导流件30，以便环形出风间隙15底部区段的气流带动其余区段的气流共同朝前上方上扬流动。通过将进气口22的位置低于第一出气口21，这样一来，环形出风间隙15底部区段相比其他区段处于气流上游，使气流会更加顺畅地先流入环形出风间隙15底部区段。基于以上两点设计，环形出风间隙15底部区段相比其余区段的风量更大，风力更强。底部强力气流在与环形出风间隙15上部和横向两侧气流的冲击、聚合过程中占据优势，更加有力地带动气流整体共同朝前上方上扬流动，实现更好的上扬送风效果。本发明实施例对风道20形状进行特别设计，使风道20的渐缩部分150的内壁的流线形状与导流件30相对部分的导流线的线型相同，能进一步减少出风阻力，提升出风强度，同时通过将进气口22的位置低于第一出气口21，使气流从下至上流向导流件30，以便环形出风间隙15底部区段的气流带动其余区段的气流共同朝前上方上扬流动。在制冷模式时，上扬流动的冷风可充分避开人体，达到最高点后再向下散落，实现一种“淋浴式”制冷体验，提高用户使用舒适性。并且，气流上扬吹出也有利于提升其送风距离。Continuing to refer to FIGS. 2, 3 and 5, in some embodiments, the streamline shape of the inner wall of the tapered portion 150 of the air duct 20 is the same as the line shape of the diversion line of the opposite portion of the air guide 30. In FIG. 3, taking the streamline of the bottom section of the tapered portion 150 as an example, it mainly includes the mn section and the np section, and the line type of the mn section is in front of the fourth arc section (de section) of the air guide 30. The line type of the section is the same, and the line type of the np section is the same as the line type of the rear section of the fifth arc-shaped section (ef section) of the air guide 30. 2 and 3, the position of the air inlet 22 is lower than the first air outlet 21, so that the air flow flows from the bottom to the top of the guide member 30, so that the air flow in the bottom section of the annular air outlet gap 15 drives the air flow in the remaining sections Together they flow upward and forward. By positioning the air inlet 22 lower than the first air outlet 21, in this way, the bottom section of the annular air outlet gap 15 is upstream of the air flow compared to other sections, so that the air flow will flow into the annular air outlet gap 15 more smoothly first. The bottom section. Based on the above two points of design, the bottom section of the annular air outlet gap 15 has a larger air volume and stronger wind than the other sections. The strong airflow at the bottom has an advantage in the impact and polymerization process with the upper and lateral sides of the annular air outlet gap 15, and more effectively drives the airflow to flow upward and forward together to achieve a better upward air supply effect. In the embodiment of the present invention, the shape of the air duct 20 is specially designed so that the streamline shape of the inner wall of the tapered portion 150 of the air duct 20 is the same as the line shape of the diversion line of the opposite part of the deflector 30, which can further reduce the wind resistance. , To increase the strength of the air outlet, and at the same time, by lowering the position of the air inlet 22 below the first air outlet 21, the airflow flows from the bottom to the upper part of the guide member 30, so that the airflow in the bottom section of the annular air outlet gap 15 drives the remaining sections The air flows upward and upward together. In the cooling mode, the rising and flowing cold air can fully avoid the human body, and then fall down after reaching the highest point, realizing a "shower-like" cooling experience and improving user comfort. In addition, the upward blowing of the airflow is also conducive to increasing the air supply distance.
在一些实施例中，立式空调室内机还包括导流件驱动机构(图中未示 出)。导流件驱动机构安装于风道20，用于支撑导流件30并驱动导流件30前后平移，以开闭第一出气口21或调节环形出风间隙15的出风面积，从而使环形出风间隙15的出风量、风速和送风距离可调，丰富了送风调节模式。导流件驱动机构可为电动伸缩杆。例如图2中标示出导流件30的最宽处与风道20的非渐缩部分的内壁的距离d1，以及导流件30的与风道20的渐缩部分150线型相同的区段与风道20的渐缩部分150的内壁的距离d2，其中d2和d1的大小之比可以为0.125-2；当移动导流件30使d1>d2时，出风集束更明显，送风距离更远；当移动导流件30使d1<d2时，出风较为扩散，送风风量大。In some embodiments, the vertical air conditioner indoor unit further includes a guide driving mechanism (not shown in the figure).

The number of the driving mechanism 90 may be one or more. For example, there are two driving mechanisms 90 arranged at intervals along the left and right directions, which are connected to the different positions of the left and right sides of the baffle 80 and act synchronously, so as to keep the baffle 80 in translation as much as possible during the movement, so as to avoid the inconsistent movement steps of its various parts. It produces skew. The baffle 80 moves up to close the second air outlet 23. At this time, the air flow in the air duct 20 flows out of the first air outlet 11 only through the first air outlet 21 (see the air flow direction in Fig. 2) to realize the upward upward air supply . When a large area of rapid air supply in the up and down direction is required, move the baffle 80 down and open the second air outlet 23.
