The airflow path of the middle air supply port is described.
本发明的空调室内机中，两个主风道之间设置有一中间风道，两个主风道内的气流可通过自身的主送风口向室内环境吹送，也可以通过旁通开口进入中间风道，由中间风道的中间送风口向室内环境吹送。并且，可利用风路切换部件导通全部两个或其中任意一个主风道的旁通开口与中间送风口之间的气流通路，以选择使两个或任意一个主风道的调节气流被“分流”至中间送风口吹出。如此一来，使被分流的主风道可选，而且也能调节中间送风口的送风量，送风模式非常多样化。In the air-conditioning indoor unit of the present invention, an intermediate air duct is arranged between the two main air ducts, and the airflow in the two main air ducts can be blown to the indoor environment through its own main air supply port, or can enter the intermediate air duct through the bypass opening. , blown to the indoor environment from the middle air outlet of the middle air duct.

The indoor unit of the air conditioner is an indoor part of the air conditioner, and is used for adjusting indoor air, such as cooling/heating, dehumidification, introducing fresh air, and the like. The present invention does not limit the style of the air-conditioning indoor unit, which can be wall-mounted, vertical, ceiling-mounted, etc. Figures 1 to 6 illustrate the embodiments of the vertical air-conditioning indoor unit.

It should be noted that each figure only shows some optional air supply modes of the present invention, and some air supply modes are not clearly listed and introduced.
如图1至图5所示，本发明实施例的空调室内机一般性地可包括机壳10和风路切换部件50。As shown in FIGS. 1 to 5 , the air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 and an air path switching component 50 .
本发明实施例所述的机壳10不仅包括用于构成室内机基本框架的骨架、面板，还包括内部的风道部件。请供参考图2，机壳10限定有两个主风道20、30和一个中间风道70。中间风道70设置在两个主风道20、30之间。每个主风道20、30具有主送风口11、13，主送风口11、13朝室内环境敞开。机壳10内制取调节气流，调节气流可为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。调节气流在主风道20、30的引导下，经主送风口11、13吹向室内环境，完成对室内环境的调节，例如制冷、制热等等。同理，中间风道70具有中间送风口12(图2示意的CD两边之间)，中间送风口12位于两个主送风口11、13之间。中间送风口12朝室内环境敞开。每个主风道20、30开设有用于向中间风道70注入调节气流的旁通开口21、31(A1-B1、A2-B2)。旁通开口21、31构成中间风道70的进气口，中间风道70的调节气流是从主风道20、30内注入的。The casing 10 described in the embodiment of the present invention not only includes a skeleton and a panel for constituting the basic frame of the indoor unit, but also includes internal air duct components. Please refer to FIG. 2 , the casing 10 defines two main air ducts 20 , 30 and a middle air duct 70 . The middle air duct 70 is arranged between the two main air ducts 20 , 30 . Each main air duct 20, 30 has a main air supply opening 11, 13 which is open to the indoor environment. The regulated airflow is produced in the casing 10, and the regulated airflow can be the cold air produced by the indoor unit of the air conditioner in the cooling mode, or the hot air produced in the heating mode. The regulated airflow is guided by the main air ducts 20 and 30 and blows to the indoor environment through the main air outlets 11 and 13 to complete the adjustment of the indoor environment, such as cooling and heating. Similarly, the middle air duct 70 has a middle air supply port 12 (between the two sides of CD shown in FIG. 2 ), and the middle air supply port 12 is located between the two main air supply ports 11 and 13 . The middle air supply port 12 is open to the indoor environment. Each main air duct 20 , 30 defines a bypass opening 21 , 31 ( A1 - B1 , A2 - B2 ) for injecting regulated airflow into the middle air duct 70 . The bypass openings 21 , 31 constitute air inlets of the intermediate air duct 70 , and the regulated airflow of the intermediate air duct 70 is injected from the main air duct 20 , 30 .
风路切换部件50可动地设置在中间风道70内，配置成受控地封闭两个旁通开口21、31与中间送风口12之间的气流通路，或选择性地导通一个或两个旁通开口21、31与中间送风口12之间的气流通路。所谓封闭“气流通路”也就是阻止相应主风道20、30的调节气流经中间送风口12向外吹出，也就是在旁通开口21、31至中间送风口12的气流路径的某个位置施加阻挡，阻碍气流的流动。导通“气流通路”也就是允许气流经某个旁通开口21、31 进入中间风道70并经中间送风口12吹出。The air path switching component 50 is movably arranged in the middle air duct 70, configured to controlably close the air flow path between the two bypass openings 21, 31 and the middle air supply port 12, or selectively conduct one or both of them. The air flow path between the bypass openings 21, 31 and the middle air outlet 12. The so-called closed "airflow path" is to prevent the regulated airflow of the corresponding main air duct 20, 30 from blowing out through the middle air supply port 12, that is, to apply airflow at a certain position of the airflow path from the bypass opening 21, 31 to the middle air supply port 12. Obstruct, impede the flow of air. Conducting the “air flow path” means allowing the air to enter the middle air channel 70 through a certain bypass opening 21 , 31 and blow out through the middle air outlet 12 .
某一个旁通开口21、31通往中间送风口12的“气流通路”被导通后，中间送风口12将仅供该主风道20、30使用，该主风道20、30的至少部分调节气流将被“分流”至中间送风口12吹出，使该主风道的出风截面变大。而另一旁通开口21、31的调节气流只能使用自身的主送风口11、13。两个旁通开口21、31相应的“气流通路”均被导通时，中间送风口12将供两个主风道20、30分流，实现共用。两个旁通开口21、31的“气流通路”均被封闭后，中间送风口12不送风，两个主风道20、30依靠各自的主送风口11、13送风。After a certain bypass opening 21, 31 leads to the "air flow passage" of the middle air supply port 12, the middle air supply port 12 will only be used by the main air duct 20, 30, and at least part of the main air duct 20, 30 The regulated airflow will be "split" to the middle air outlet 12 to be blown out, so that the air outlet section of the main air duct becomes larger. And the regulated air flow of the other bypass opening 21, 31 can only use its own main air supply port 11, 13. When the corresponding "air flow passages" of the two bypass openings 21, 31 are connected, the middle air supply port 12 will be used for the two main air ducts 20, 30 to share the flow. After the "airflow paths" of the two bypass openings 21, 31 are closed, the middle air supply port 12 does not supply air, and the two main air ducts 20, 30 rely on the respective main air supply ports 11, 13 to supply air.
由此可见，风路切换部件50通过自身的动作，能选择使全部两个或其中任意一个主风道20、30的调节气流被“分流”至中间送风口12吹出。也就是能选择将中间风道70交给哪个主风道20、30使用。如此一来，既能调节每个主送风口11、13的送风量，也能调节中间送风口12的送风量，送风模式非常多样化。It can be seen that, through its own action, the air path switching component 50 can select to make the regulated air flow of all two or any one of the main air channels 20 , 30 be “split” to the middle air outlet 12 to be blown out. That is, it is possible to select which main air duct 20, 30 to use the intermediate air duct 70 for. In this way, not only the air supply volume of each main air supply port 11, 13, but also the air supply volume of the middle air supply port 12 can be adjusted, and the air supply modes are very diverse.
例如图2所示，风路切换部件50将两个旁通开口21、31与中间送风口12之间的气流通路均被封闭，使得中间送风口12未被启用。如图3，仅使右侧主风道30的旁通开口31与中间送风口12之间的“气流通路”被导通，以使右侧主风道30借用中间送风口12送风，使右侧主出风口13的风量变小。如图4，仅使左侧主风道20的旁通开口21与中间送风口12之间的“气流通路”被导通，以使左侧主风道20借用中间送风口12送风，使左侧主出风口11的风量变小。如图5所示，可使两个主风道20、30的旁通开口21、31与中间送风口12之间的“气流通路”均被导通，使两个主风道20、30均利用中间送风口12送风，使中间送风口12的送风量更大。For example, as shown in FIG. 2 , the air path switching component 50 closes the airflow paths between the two bypass openings 21 , 31 and the middle air outlet 12 , so that the middle air outlet 12 is not activated. As shown in Figure 3, only the "air flow path" between the bypass opening 31 of the right side main air duct 30 and the middle air supply port 12 is conducted, so that the right side main air duct 30 borrows the middle air supply port 12 to supply air, so that The air volume of the right main air outlet 13 becomes smaller. As shown in Figure 4, only the "air flow path" between the bypass opening 21 of the left main air duct 20 and the middle air supply port 12 is conducted, so that the left main air duct 20 borrows the middle air supply port 12 to supply air, so that The air volume of the left main air outlet 11 becomes smaller. As shown in Figure 5, the "air flow path" between the bypass openings 21, 31 of the two main air ducts 20, 30 and the middle air supply port 12 can be conducted, so that the two main air ducts 20, 30 can Utilize the middle air supply port 12 to supply air, so that the air supply volume of the middle air supply port 12 is larger.
在一些实施例中，可使中间风道70至少邻近中间送风口12的区段(即出口段)为使出风截面沿气流方向逐渐变小的渐缩状。如图5，使中间风道70由横向间隔设置的第一侧壁301和第二侧壁302，以及位于后侧的后壁303限定出。使第一侧壁301和第二侧壁302的出口段(S截面以前区段)的间距沿气流方向逐渐变小。如此一来，两个旁通开口21、31与中间送风口12的之间气流通路均被导通时，如图5，使气流在中间风道70的渐缩状内壁的引导下逐渐汇聚，从而在中间送风口12外侧形成聚合，汇聚成一股，使得风力非常强劲，送风距离更远，满足了空调室内机对远距离送风和强劲送风 的需求。由此，本发明实施例的空调室内机既可通过主送风口11、13实现常规送风，又能通过中间送风口12实现聚合送风，送风方式更加多样化，拥有多种送风模式，以充分满足用户不同情况的不同需求。In some embodiments, at least a section of the middle air channel 70 adjacent to the middle air outlet 12 (ie, the outlet section) can be tapered so that the air outlet cross section gradually becomes smaller along the airflow direction. As shown in FIG. 5 , the middle air duct 70 is defined by a first side wall 301 and a second side wall 302 arranged at intervals in the transverse direction, and a rear wall 303 located at the rear side. Make the distance between the outlet sections of the first side wall 301 and the second side wall 302 (the section before the S section) gradually decrease along the airflow direction. In this way, when the airflow paths between the two bypass openings 21, 31 and the middle air supply port 12 are all connected, as shown in Figure 5, the airflow is gradually converged under the guidance of the tapered inner wall of the middle air duct 70, Thereby, aggregation is formed on the outside of the middle air supply port 12, converging into one strand, making the wind force very strong, and the air supply distance is longer, which meets the needs of the air conditioner indoor unit for long-distance air supply and strong air supply. Therefore, the air-conditioning indoor unit of the embodiment of the present invention can realize conventional air supply through the main air supply outlets 11 and 13, and can realize aggregated air supply through the intermediate air supply outlet 12, and the air supply mode is more diversified, and has multiple air supply modes , to fully meet the different needs of users in different situations.
在图1至图5所示实施例中，机壳10为竖直延伸的柱状，也就是使空调室内机为立式空调室内机或者立式壁挂机。当然，与机壳10的形状相匹配地，主风道20、30、主送风口11、13、中间风道70和中间送风口12均为竖条状。两个主风道20、30沿机壳10的横向排列，中间送风口12朝前敞开，两个主送风口11、13分列于中间送风口12的横向两侧。可使两个主送风口11、13均朝前敞开，也可使两个主送风口11、13朝侧前方敞开，以扩大空调室内机的整体送风角度范围。例如图1至图5所示，使左侧的主送风口11朝左前方敞开，使右侧的主送风口13朝右前方敞开。主送风口11、13处可设置有导风装置，例如导叶60，以对主送风口11、13的送风方向进行引导。In the embodiments shown in FIGS. 1 to 5 , the casing 10 is in the shape of a column extending vertically, that is, the air conditioner indoor unit is a vertical air conditioner indoor unit or a vertical wall-mounted unit. Certainly, to match the shape of the casing 10 , the main air ducts 20 , 30 , the main air supply ports 11 , 13 , the middle air duct 70 and the middle air supply port 12 are all in the shape of vertical bars. The two main air ducts 20, 30 are arranged laterally along the casing 10, the middle air supply opening 12 is open to the front, and the two main air supply openings 11, 13 are arranged on the lateral sides of the middle air supply opening 12. The two main air supply ports 11, 13 can be opened to the front, or the two main air supply ports 11, 13 can be opened to the front side, so as to expand the overall air supply angle range of the air conditioner indoor unit. For example, as shown in FIGS. 1 to 5 , the left main air outlet 11 is opened toward the left front, and the right main air outlet 13 is opened toward the right front. Air guide devices, such as guide vanes 60 , may be provided at the main air outlets 11 and 13 to guide the air supply direction of the main air outlets 11 and 13 .
当然，另一些实施例中，也可使空调室内机为壁挂式，使机壳为长度方向水平延伸的长条状，使主风道、主送风口、中间风道和中间送风口相应均为水平横向延伸的长条状，具体不再赘述。Of course, in some other embodiments, the indoor unit of the air conditioner can also be wall-mounted, the casing can be a long strip extending horizontally in the length direction, and the main air duct, the main air supply port, the middle air duct and the middle air supply port can be Long strips extending horizontally and horizontally, details will not be repeated here.
下面参照图2至图5介绍本发明实施例的风路切换部件50。The air path switching component 50 according to the embodiment of the present invention will be described below with reference to FIG. 2 to FIG. 5 .
如图2至图5所示，风路切换部件50为中空筒状。对于立式空调室内机，风路切换部件50的轴向平行于竖直方向。风路切换部件50的周壁包括沿其周向排列的至少两个通风区段52、53，以允许气流经通风区段52、53进出风路切换部件50的内腔，两个旁通开口21、31与中间送风口12围绕在风路切换部件50的外周。例如，可使中间风道70大致为筒状，其轴向平行于风路切换部件50的轴向。中间风道70的外周具有间隔设置的后壁303和两个侧壁301、302。后壁303与两个侧壁301、302之间的间隔分别构成两个旁通开口21、31，两个侧壁301、302之间的间隔构成中间送风口12。As shown in FIGS. 2 to 5 , the air passage switching member 50 has a hollow cylindrical shape. For the vertical air conditioner indoor unit, the axial direction of the air path switching component 50 is parallel to the vertical direction. The peripheral wall of the air path switching component 50 includes at least two ventilation sections 52, 53 arranged along its circumference, to allow air to pass through the ventilation sections 52, 53 into and out of the inner cavity of the air path switching component 50, and the two bypass openings 21 , 31 and the middle air outlet 12 surround the outer periphery of the air path switching component 50 . For example, the intermediate air passage 70 may be substantially cylindrical, and its axial direction is parallel to the axial direction of the air passage switching member 50 . The outer periphery of the middle air duct 70 has a rear wall 303 and two side walls 301 , 302 arranged at intervals. The distance between the rear wall 303 and the two side walls 301 , 302 constitutes two bypass openings 21 , 31 respectively, and the distance between the two side walls 301 , 302 constitutes the middle air outlet 12 .
风路切换部件50可受控地转动，以在转动至使两个通风区段52、53分别与一个旁通开口21、31和中间送风口12相对的位置时，使两者间的气流通路被导通。此时，主风道20、30的调节气流经旁通开口21、31和一个通风区段52、53进入风路切换部件50的内腔，然后经另一通风区段52、53流出然后吹出中间送风口12。而另一旁通开口21、31由于没有与通风区段52、53相对，其气流无法进入风路切换部件50的内腔。如图2所示，每个 通风区段52、53形成有通风格栅，以使风路切换部件50的结构强度更高。此外，也可使每个通风区段52、53形成有多个通风孔，以允许气流进出。或者，也可使每个通风区段52、53为单纯的开口。通风格栅可以采用本领域技术人员所习知的格栅结构。本公开对此不作赘述。The air path switching part 50 can be rotated in a controlled manner, so that when the two ventilation sections 52, 53 are respectively opposite to a bypass opening 21, 31 and the middle air supply port 12, the air flow passage between the two can be controlled. is turned on. At this time, the regulated airflow of the main air duct 20, 30 enters the inner cavity of the air path switching component 50 through the bypass opening 21, 31 and a ventilation section 52, 53, then flows out through the other ventilation section 52, 53 and then blows out Middle air supply port 12. Since the other bypass openings 21 , 31 are not opposite to the ventilation sections 52 , 53 , the airflow thereof cannot enter the inner cavity of the air path switching component 50 . As shown in FIG. 2 , each ventilation section 52, 53 is formed with a ventilation grille, so that the structural strength of the air path switching component 50 is higher. In addition, each ventilation section 52, 53 may also be formed with a plurality of ventilation holes to allow airflow in and out. Alternatively, each ventilation section 52 , 53 can also be a simple opening. The ventilation grill can adopt a grill structure known to those skilled in the art. This disclosure does not repeat this.
如图2至图5所示，可使风路切换部件50仅包括两个通风区段52、53。可以理解的是，也可以设置更多的通风区段52、53。本发明实施例这种转动筒状的风路切换部件结构简单巧妙，而且运动控制也非常简单，仅需驱动一个部件的转动即可。As shown in FIGS. 2 to 5 , the air path switching component 50 may only include two ventilation sections 52 , 53 . It is understood that more ventilation sections 52 , 53 can also be provided. In the embodiment of the present invention, the rotating cylinder-shaped air path switching component has a simple and ingenious structure, and the motion control is also very simple, and only one component needs to be driven to rotate.
例如图2至图5所示，可使中空筒状的风路切换部件50整体为棱柱状。棱柱具有多个侧壁和轴向的两个端壁。例如，三棱柱具有三个侧壁，四棱柱具有四个侧壁。多个侧壁中的至少部分侧壁构成通风区段52、53。For example, as shown in FIGS. 2 to 5 , the hollow cylindrical air passage switching member 50 may be formed in a prismatic shape as a whole. The prism has multiple side walls and two axial end walls. For example, a triangular prism has three side walls and a quadrangular prism has four side walls. At least some of the side walls form ventilation sections 52 , 53 .
例如，可使风路切换部件50整体为三棱柱状，其三个侧壁分别构成两个通风区段52、53和一个阻风侧壁51。风路切换部件50配置成可转动至使阻风侧壁51与中间送风口12相对，以使中间送风口12被封闭的位置，如图2，此时中间送风口12无法出风；或转动至使两个通风区段52、53分别与一个旁通开口21、31和中间送风口12相对，并使阻风侧壁51与另一旁通开口21、31相对的位置，以仅导通一个旁通开口21、31与中间送风口12的气流通路，如图3、图4。For example, the wind path switching component 50 can be made in the shape of a triangular prism as a whole, and its three side walls respectively form two ventilation sections 52 , 53 and a wind-blocking side wall 51 . The wind path switching part 50 is configured to be rotatable to make the wind-blocking side wall 51 and the middle air supply port 12 opposite, so that the position where the middle air supply port 12 is closed, as shown in Figure 2, at this time the middle air supply port 12 cannot discharge the wind; or rotate To make the two ventilation sections 52, 53 opposite to one bypass opening 21, 31 and the middle air supply port 12 respectively, and make the wind blocking side wall 51 opposite to the other bypass opening 21, 31, so as to conduct only one The air flow paths between the bypass openings 21, 31 and the middle air supply port 12 are shown in Fig. 3 and Fig. 4 .
优选地，如图2所示，使风路切换部件50整体为正三棱柱状，使其转动轴线平行于正三棱的几何中心轴线。风路切换部件50运动至图2至图4的位置以导通/关闭气流通路时，使正三棱柱的棱边与中间风道70的内壁抵靠或者接近，以避免或减少漏风。Preferably, as shown in FIG. 2 , the air path switching component 50 is made in the shape of a regular triangular prism as a whole, and its rotation axis is parallel to the geometric central axis of the regular triangular prism. When the air path switching component 50 moves to the positions shown in FIGS. 2 to 4 to turn on/off the airflow path, the edges of the regular triangular prism abut or approach the inner wall of the middle air duct 70 to avoid or reduce air leakage.
可以理解的是，本发明实施例使风路切换部件50整体为三棱柱状，仅仅是因为恰好使三棱柱的三个侧壁与两个旁通开口21、31与中间送风口12(共三个开口)相对，因此无需使风路切换部件50为严格几何意义的三棱柱。实际设计制作过程中，其棱边也可设置圆角，侧面也可设计为非平面，例如弧面等等。当然，也可以使风路切换部件50为四棱柱状、五棱柱状。此外，也可使风路切换部件50为圆筒状或者椭圆筒状。诸如此类的改进是本领域技术人员容易理解和作出的，在此不做过多介绍。It can be understood that the embodiment of the present invention makes the air path switching component 50 a triangular prism as a whole, just because the three side walls of the triangular prism, the two bypass openings 21, 31 and the middle air supply port 12 (a total of three openings) are opposite, so there is no need to make the air path switching component 50 a triangular prism in a strict geometric sense. In the actual design and production process, the edges can also be rounded, and the sides can also be designed as non-planar surfaces, such as curved surfaces. Of course, the air passage switching member 50 may also be in the shape of a square prism or a pentagonal prism. In addition, the air path switching member 50 may be formed into a cylindrical shape or an elliptical cylindrical shape. Improvements such as these are easily understood and made by those skilled in the art, and will not be introduced here.
如图5所示，也可使风路切换部件50配置成可转动至使其三个棱边分别与两个旁通开口21、31和中间送风口12相对的位置，以同时导通两个旁 通开口21、31与中间送风口12的气流通路。如前所述，此时可利用中间送风口12进行聚合送风。由于风路切换部件50的一个棱边对中间送风口12相对，该棱边两侧的侧壁(例如为通风区段52、53)从后向前逐渐接近并在棱边处相接，以恰好利用该两个侧壁的斜度来引导两侧的出风气流进行聚合，使聚合效果更好。As shown in FIG. 5 , the air path switching member 50 can also be configured to be rotatable to a position where its three edges are respectively opposite to the two bypass openings 21, 31 and the middle air supply port 12, so as to simultaneously conduct two The bypass openings 21 , 31 and the airflow path of the middle air outlet 12 . As mentioned above, at this time, the central air supply port 12 can be used for aggregated air supply. Since one edge of the wind path switching component 50 is opposite to the middle air supply port 12, the side walls (such as the ventilation sections 52, 53) on both sides of the edge gradually approach from the back to the front and meet at the edge to The inclination of the two side walls is just used to guide the outflow airflow on both sides to aggregate, so that the aggregation effect is better.
图6是本发明另一实施例的空调室内机的示意图。Fig. 6 is a schematic diagram of an air conditioner indoor unit according to another embodiment of the present invention.
本发明实施例中的风路切换部件50可为单个部件，例如图1至图5所示的实施例即如此。此外，风路切换部件也可为多个部件的组合。The air path switching component 50 in the embodiment of the present invention may be a single component, such as the embodiments shown in FIGS. 1 to 5 . In addition, the wind path switching component may also be a combination of multiple components.
例如图6所示，可使风路切换部件包括两个风门91、92，每个风门设置在一个旁通开口21、31处，以用于受控地开闭对应的旁通开口21、31。当仅一个风门91、92打开时，该风门91、92对应旁通开口21、31与中间送风口12之间的气流通路被导通。具体地，可使风门91、92可转动地设置在旁通开口21、31处，以转动地开闭旁通开口21、31。在一些替代性实施例中，也可使风门91、92可平移地开闭旁通开口21、31，具体结构不再赘述。For example, as shown in FIG. 6 , the air path switching component may include two dampers 91 , 92 , each damper is arranged at a bypass opening 21 , 31 for controlled opening and closing of the corresponding bypass opening 21 , 31 . When only one damper 91 , 92 is opened, the airflow path between the corresponding bypass openings 21 , 31 and the middle air outlet 12 of the damper 91 , 92 is conducted. Specifically, the dampers 91 , 92 can be rotatably arranged at the bypass openings 21 , 31 so as to rotatably open and close the bypass openings 21 , 31 . In some alternative embodiments, the dampers 91, 92 can also be opened and closed the bypass openings 21, 31 in a translational manner, and the specific structure will not be repeated here.
如图2所示，可使每个主风道20、30的进口处设置有一贯流风机80，空调室内机还包括换热器40，换热器40位于两个贯流风机80后方，换热器40的横向两侧向前弯折，以使其两个边缘分别抵靠于两个主风道20、30的内壁。机壳10的进风口(未图示)开设于机壳10的后壁，在贯流风机80的作用下，室内气流从进风口进入机壳10，与换热器40完成换热，然后进入两个主风道20、30。由于换热器40已经完全封堵两个主风道20、30的进口，使得换热气流完全进入两个主风道20、30，避免风量浪费。As shown in Figure 2, a cross-flow fan 80 can be installed at the entrance of each main air duct 20, 30, and the indoor unit of the air conditioner also includes a heat exchanger 40, and the heat exchanger 40 is located behind the two cross-flow fans 80. The lateral sides of the heater 40 are bent forward so that its two edges abut against the inner walls of the two main air ducts 20 , 30 respectively. The air inlet (not shown) of the casing 10 is opened on the rear wall of the casing 10, and under the action of the cross-flow fan 80, the indoor airflow enters the casing 10 from the air inlet, completes heat exchange with the heat exchanger 40, and then enters the Two main air ducts 20,30. Since the heat exchanger 40 has completely blocked the inlets of the two main air passages 20, 30, the heat exchange air flow completely enters the two main air passages 20, 30, avoiding waste of air volume.
图7是本发明的空调室内机的控制方法的示意图。Fig. 7 is a schematic diagram of the control method of the air conditioner indoor unit of the present invention.
如图7所示，本发明还提供了一种空调室内机的控制方法，用于控制如以上任一实施例的空调室内机，其包括如下步骤：As shown in FIG. 7 , the present invention also provides a control method for an air conditioner indoor unit, which is used to control the air conditioner indoor unit in any of the above embodiments, which includes the following steps:
步骤S702：检测人体所处位置，确定与人体距离更近的主送风口11、13。例如图1至图6所示实施例中，两个主送风口11、13横向设置。如图1，确定与人体距离更近的主送风口11、13，可以两个主送风口11、13之间的中央对称平面Y(两个主送风口11、13的中央相对于Y对称)作为分界面，由该分界面Y将室内空间分为S1和S2两个区域，当人体处于S1区域时，距离左侧的主送风口11更近，当人体处于S2区域时，距离右侧的主送风口13更近。具体地，可利用传感器检测人体所处位置。Step S702: Detect the position of the human body, and determine the main air outlets 11, 13 that are closer to the human body. For example, in the embodiment shown in Fig. 1 to Fig. 6, two main air supply ports 11, 13 are arranged laterally. As shown in Figure 1, to determine the main air supply ports 11, 13 closer to the human body, the central symmetry plane Y between the two main air supply ports 11, 13 (the center of the two main air supply ports 11, 13 is symmetrical to Y) As an interface, the interface Y divides the indoor space into two areas, S1 and S2. When the human body is in the S1 area, it is closer to the main air outlet 11 on the left, and when the human body is in the S2 area, it is closer to the main air outlet 11 on the right The main air supply port 13 is closer. Specifically, the sensor can be used to detect the position of the human body.
步骤S704：控制风路切换部件50运动，导通与人体距离更近的主送风口11、13所对应的风道的旁通开口21、31与中间送风口12的气流通路，封闭另一旁通开口21、31与中间送风口12的气流通路。Step S704: Control the movement of the air path switching component 50 to connect the bypass openings 21, 31 of the air ducts corresponding to the main air outlets 11, 13 closer to the human body and the air flow path between the middle air outlet 12, and close the other bypass The airflow path between the openings 21 and 31 and the middle air outlet 12 .
例如，当检测到人体距右侧的主送风口13距离更近时，即判断人体在空调室内机靠右侧的区域，便如图3所示，仅使右侧主风道30的旁通开口31与中间送风口12之间的“气流通路”被导通，以使右侧主风道30借用中间送风口12送风，使右侧主出风口13的风量变小，风速降低，避免强风直吹人体导致不适。For example, when it is detected that the human body is closer to the main air outlet 13 on the right side, it is judged that the human body is in the area on the right side of the air-conditioning indoor unit, and as shown in Figure 3, only the bypass of the main air duct 30 on the right side The "air flow path" between the opening 31 and the middle air outlet 12 is connected, so that the right main air duct 30 borrows the middle air outlet 12 to supply air, so that the air volume of the right main air outlet 13 becomes smaller and the wind speed is reduced, avoiding The strong wind directly blows the human body causing discomfort.
同理，当到检测到人体距左侧的主送风口11距离更近时，即判断人体在空调室内机靠右侧的区域，便如图4所示，仅使左侧主风道20的旁通开口21与中间送风口12之间的“气流通路”被导通，以使左侧主风道20借用中间送风口12送风，使左侧主出风口11的风量变小，风速降低，避免强风直吹人体导致不适。Similarly, when it is detected that the human body is closer to the main air outlet 11 on the left side, it is judged that the human body is in the area near the right side of the air-conditioning indoor unit, and as shown in Figure 4, only the left side of the main air duct 20 The "airflow path" between the bypass opening 21 and the middle air outlet 12 is connected, so that the left main air duct 20 borrows the middle air outlet 12 to supply air, so that the air volume and wind speed of the left main air outlet 11 become smaller , Avoid strong wind blowing directly on the human body and causing discomfort.
总之，本发明实施例的控制方法中，空调室内机根据人体位置选择需要被分流的主风道20、30，使与人体距离更近的主送风口11、13所对应主风道20、30的调节气流被“分流”至中间送风口12吹出，以使该主风道20、30的总出风截面更大，使其气流冲击力更小，使人体的风感更舒适。In short, in the control method of the embodiment of the present invention, the indoor unit of the air conditioner selects the main air ducts 20, 30 that need to be diverted according to the position of the human body, so that the main air ducts 20, 30 corresponding to the main air outlets 11, 13 that are closer to the human body The regulated airflow is "split" to the middle air supply port 12 to blow out, so that the total air outlet cross section of the main air ducts 20, 30 is larger, the impact force of the airflow is smaller, and the wind feeling of the human body is more comfortable.
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。So far, those skilled in the art should appreciate that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, without departing from the spirit and scope of the present invention, the disclosed embodiments of the present invention can still be used.
