本发明的空调室内机中，新风风机具有第一新风出口和新风内出口，两者可同时或择一开启，以使新风气流同时流向室内环境和所述机壳内部，或流向两者之一。新风气流若从第一新风出口流出，将通过第一新风出风口直 接流向室内环境；新风气流若从新风内出口流向机壳内部，将与机壳内的换热气流混合或者直接流向换热器进行换热后，再经机壳的换热出风口排向室内环境。如此，空调可根据实际送风需要来选择新风的流出路径，达到最优的新风效果。例如，当只有新风需求，没有制冷制热需求时，可选择由第一新风出口出风，使空调的换热部分(换热器、换热风机、换热出风口等)不工作。当空调在制冷/制热的同时需要换新风时，可使新风内出口出风，使新风气流提前在机壳内完成制冷/制热过程，以使最终到达室内的新风已经为温度适宜的新风气流。当然，还可使第一新风出口和新风内出口同时出风，以使新风风量达到最大。本发明使得空调室内机具有多种新风送风模式，功能非常强大，使用户拥有更多选择。In the air-conditioning indoor unit of the present invention, the fresh air fan has a first fresh air outlet and a fresh air inner outlet, both of which can be opened at the same time or alternatively, so that the fresh air flows to the indoor environment and the inside of the casing at the same time, or to one of the two. . If the fresh air flows out from the first fresh air outlet, it will directly flow to the indoor environment through the first fresh air outlet; if the fresh air flows from the fresh air inner outlet to the inside of the cabinet, it will mix with the heat exchange air in the cabinet or flow directly to the heat exchanger After heat exchange, it is discharged to the indoor environment through the heat exchange air outlet of the casing. In this way, the air conditioner can select the outflow path of the fresh air according to the actual air supply needs, so as to achieve the optimal fresh air effect. For example, when there is only demand for fresh air and no demand for cooling and heating, the first fresh air outlet can be selected to discharge air, so that the heat exchange part of the air conditioner (heat exchanger, heat exchange fan, heat exchange air outlet, etc.) does not work. When the air conditioner needs to replace the fresh air while cooling/heating, the fresh air outlet can let out the air, so that the fresh air flow can complete the cooling/heating process in the cabinet in advance, so that the fresh air that finally reaches the room is fresh air with a suitable temperature airflow. Of course, the first fresh air outlet and the fresh air inner outlet can also be made to discharge air at the same time, so that the fresh air volume can be maximized. The invention enables the indoor unit of the air conditioner to have multiple fresh air supply modes, has very powerful functions, and enables users to have more choices.
进一步地，本发明的空调室内机中，新风风机包括水箱、第二电机和搅水轮。在必要时，搅水轮搅动水箱中的水，对新风风机吸入的空气进行加湿，避免引入室外干燥新风导致室内湿度降低，结构简单巧妙，非常实用。Further, in the air conditioner indoor unit of the present invention, the fresh air blower includes a water tank, a second motor and a water stirring wheel. When necessary, the stirring wheel stirs the water in the water tank to humidify the air inhaled by the fresh air fan, so as to avoid the reduction of indoor humidity caused by the introduction of outdoor dry fresh air. The structure is simple and ingenious, and is very practical.
进一步地，本发明的新风风机和空调室内机中，新风风机具有回风口，能够吸入非新风气流，例如室内空气或者是换热气流(冷风或热风)。可使回风口和新风进口能同时开启，使得新风气流与换热气流或室内空气混合后吹出，提前完成新风与其他气流的混合过程，加快了室内空气的更新速度。也可使回风口和新风进口择一开启，并使回风口吸入换热气流，当室内没有新风需求时，使得新风风机承担换热气流的吹送工作，加快室内制冷/制热速度。总之，回风口的设置极大丰富了新风风机的功能，设计非常巧妙。Further, in the fresh air blower and the air conditioner indoor unit of the present invention, the fresh air blower has an air return port capable of inhaling non-fresh air flow, such as indoor air or heat exchange airflow (cold wind or hot wind). The return air outlet and the fresh air inlet can be opened at the same time, so that the fresh air is mixed with the heat exchange air or indoor air and then blown out. The mixing process of the fresh air and other air is completed in advance, and the renewal speed of the indoor air is accelerated. It is also possible to open one of the return air outlet and the fresh air inlet, and make the return air inlet inhale heat exchange air. When there is no demand for fresh air in the room, the fresh air fan will undertake the work of blowing the heat exchange air to speed up the indoor cooling/heating speed. In short, the setting of the return air outlet greatly enriches the functions of the fresh air fan, and the design is very ingenious.

本发明实施例提供了一种空调室内机。空调室内机用于调节室内空气，例如制冷、制热、除湿、引入新风等等。新风气流被空调室内机从外界环境引入，并吹向室内环境中，完成对室内环境空气的更新，使室内环境的空气保持清新，有利于人体健康。An embodiment of the present invention provides an air conditioner indoor unit. The air conditioner indoor unit is used to adjust indoor air, such as cooling, heating, dehumidification, introducing fresh air, and so on. The fresh air flow is introduced from the external environment by the indoor unit of the air conditioner, and blows into the indoor environment to complete the renewal of the indoor ambient air, keeping the indoor ambient air fresh and beneficial to human health.
空调室内机可为利用蒸气压缩制冷循环系统进行制冷/制热的分体式房间空调器的室内部分。空调室内机内设置有蒸发器和换热风机。蒸发器、节流装置与设置于空调室外壳体内的压缩机、冷凝器以及其他的制冷元件通过管路相连接，构成一蒸气压缩制冷循环系统。在换热风机的作用下，室内空气经换热进风口11进入空调室内机的机壳10的内部，与蒸发器完成强制对流换热后，形成热交换风，然后吹向机壳10的换热出风口12，最终吹向室内环境，完成对室内环境空气的调节过程。The air-conditioning indoor unit may be an indoor part of a split-type room air conditioner that utilizes a vapor compression refrigeration cycle system for cooling/heating. The air conditioner indoor unit is provided with an evaporator and a heat exchange fan. The evaporator and throttling device are connected with the compressor, condenser and other refrigerating components arranged in the outdoor housing of the air conditioner through pipelines to form a vapor compression refrigerating cycle system. Under the action of the heat exchanging fan, the indoor air enters the inside of the casing 10 of the air conditioner indoor unit through the heat exchanging air inlet 11, and after completing the forced convection heat exchange with the evaporator, the heat exchanging air is formed, and then blows to the exchanging air of the casing 10. The hot air outlet 12 finally blows to the indoor environment to complete the adjustment process of the indoor ambient air.

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和新风风机20。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 a fresh air blower 20 .
机壳10限定有容纳空间，以用于容纳空调室内机的各部件，包括蒸发器、换热风机等。机壳10开设有用于排出新风气流的第一新风出风口14。The casing 10 defines an accommodating space for accommodating various components of the air conditioner indoor unit, including an evaporator, a heat exchange fan, and the like. The casing 10 defines a first fresh air outlet 14 for discharging fresh air.
新风风机20安装在机壳10的内部，用于促使新风气流流动。新风风机20包括外壳100。外壳100开设有用于吸入新风气流的新风进口110、与第一新风出风口14连接的第一新风出口124以及朝向机壳10内部的新风内出口126。可使新风进口110通过管路连通室外环境，以引入新风气流。The fresh air blower 20 is installed inside the casing 10 for promoting the flow of fresh air. The fresh air blower 20 includes a casing 100 . The casing 100 defines a fresh air inlet 110 for inhaling fresh air, a first fresh air outlet 124 connected to the first fresh air outlet 14 , and a fresh air inner outlet 126 facing inside the casing 10 . The fresh air inlet 110 can be connected to the outdoor environment through pipelines to introduce fresh air.
新风风机20配置成：使第一新风出口124和新风内出口126同时或择一开启，以使新风气流同时流向室内环境和机壳10内部，或流向两者之一。The fresh air blower 20 is configured to: open the first fresh air outlet 124 and the fresh air inner outlet 126 at the same time or alternatively, so that the fresh air flows to the indoor environment and the inside of the cabinet 10 at the same time, or to one of them.
具体地，例如图4所示，使第一新风出口124打开，使新风内出口126关闭，新风气流从第一新风出口124流出，然后从机壳10的第一新风出风口14直接流向室内环境。当室内用户只有新风需求，没有制冷制热需求时，可选择由第一新风出口124出风，使空调的换热部分(换热器、换热风机、换热出风口等)不工作。Specifically, for example, as shown in FIG. 4 , the first fresh air outlet 124 is opened, the fresh air inner outlet 126 is closed, and the fresh air flow flows out from the first fresh air outlet 124, and then directly flows from the first fresh air outlet 14 of the casing 10 to the indoor environment. . When the indoor user only needs fresh air, but not cooling and heating, the first fresh air outlet 124 can be selected to discharge air, so that the heat exchange part (heat exchanger, heat exchange fan, heat exchange air outlet, etc.) of the air conditioner does not work.
或者，例如图5所示，使第一新风出口124关闭，使新风内出口126打开，新风气流从新风内出口126流向机壳10的内部，与机壳10内的换热气流混合或者直接流向换热器进行换热后，再经机壳10的换热出风口12排向室内环境。当空调在制冷/制热的同时需要换新风时，可使新风内出口126出风，使新风气流提前在机壳10内完成制冷/制热过程，以使最终到达室内的新风已经为温度适宜的新风气流，避免在新风气流温度过高或过低时直吹室内导致室内环境舒适度受到影响。Or, for example, as shown in FIG. 5 , the first fresh air outlet 124 is closed, the fresh air inner outlet 126 is opened, and the fresh air flow flows from the fresh air inner outlet 126 to the inside of the casing 10 to mix with the heat exchange airflow in the casing 10 or directly flow to After the heat exchanger performs heat exchange, it is discharged to the indoor environment through the heat exchange air outlet 12 of the casing 10 . When the air conditioner needs fresh air while cooling/heating, the fresh air inner outlet 126 can be used to discharge the air, so that the fresh air flow can complete the cooling/heating process in the casing 10 in advance, so that the fresh air that finally reaches the room is already at a suitable temperature. The fresh air flow can avoid direct blowing of the fresh air into the room when the temperature of the fresh air is too high or too low, which will affect the comfort of the indoor environment.
或者，还可使第一新风出口124和新风内出口126同时出风，以使新风风量达到最大。Alternatively, the first fresh air outlet 124 and the fresh air internal outlet 126 can also be made to discharge air at the same time, so as to maximize the fresh air volume.
由上可知，本发明实施例的空调室内机具有多种新风送风模式，功能非常强大，使用户拥有更多选择。空调可根据室内实际送风需要来选择新风的流出路径，以达到最优的新风效果。It can be seen from the above that the air conditioner indoor unit of the embodiment of the present invention has multiple fresh air supply modes, which are very powerful and allow users to have more choices. The air conditioner can select the outflow path of the fresh air according to the actual indoor air supply needs, so as to achieve the optimal fresh air effect.
如图1和图2所示，本发明的空调室内机可为壁挂式，其机壳10为水平横向延伸的长条状。新风风机20可设置在机壳10内部横向一侧，例如图中方案将新风风机20设置在机壳10内的左端部，以减轻其对换热进风口11、换热出风口12、蒸发器、换热风机的正常布局的影响。本实施例仅以壁挂式为例对空调室内机进行介绍，并不对空调室内机的结构形式进行限制，空调室内机也可为落地式空调室内机、吊顶式空调室内机或其他各种机型。As shown in Figures 1 and 2, the air conditioner indoor unit of the present invention can be wall-mounted, and its casing 10 is in the shape of a strip extending horizontally and laterally. The fresh air blower 20 can be arranged on the inner lateral side of the casing 10. For example, in the scheme in the figure, the fresh air blower 20 is arranged on the left end of the casing 10 to reduce its impact on the heat exchange air inlet 11, the heat exchange air outlet 12, and the evaporator. , The impact of the normal layout of the heat exchange fan. This embodiment only uses the wall-mounted indoor unit as an example to introduce the air-conditioning indoor unit, and does not limit the structural form of the air-conditioning indoor unit. The air-conditioning indoor unit can also be a floor-standing air-conditioning indoor unit, a ceiling-mounted air-conditioning indoor unit or other types. .
在一些实施例中，如图4所示，新风风机20还包括风门210和第一电机211。风门210的一端可枢转地安装于外壳100，且转动轴线位于第一新风出口124和新风内出口126之间，以转动至封闭第一新风出口124、打开新风内出口126的位置(如图5)，或转动至封闭新风内出口126、打开第一新风出口124的位置(如图4)，或转动至同时打开第一新风出口124和新风内出口126的位置(未图示，处于图4和图5中间的位置)。第一电机211配置成受控地驱动风门210转动。In some embodiments, as shown in FIG. 4 , the fresh air fan 20 further includes a damper 210 and a first motor 211 . One end of the damper 210 is pivotably mounted on the casing 100, and the axis of rotation is between the first fresh air outlet 124 and the inner fresh air outlet 126, so as to rotate to the position of closing the first fresh air outlet 124 and opening the inner fresh air outlet 126 (as shown in the figure 5), or rotate to the position of closing the fresh air outlet 126 and opening the first fresh air outlet 124 (as shown in Figure 4), or turn to the position of opening the first fresh air outlet 124 and the fresh air outlet 126 at the same time (not shown, in the figure 4 and the position in the middle of Fig. 5). The first motor 211 is configured to controlly drive the damper 210 to rotate.
图6是根据本发明一个实施例的第一电机与风门的配合结构示意图。Fig. 6 is a schematic diagram of the cooperative structure of the first motor and the damper according to an embodiment of the present invention.
具体地，如图4至图6所示，可使第一电机211安装于外壳100的外部，利用其安装耳部2113与外壳100紧固连接。第一电机211的转轴2112通过外壳100的开孔伸入外壳100内部，以与风门210固定连接。Specifically, as shown in FIG. 4 to FIG. 6 , the first motor 211 can be installed on the outside of the housing 100 , and be firmly connected with the housing 100 by using its mounting ears 2113 . The rotating shaft 2112 of the first motor 211 protrudes into the casing 100 through the opening of the casing 100 to be fixedly connected with the damper 210 .
在一些替代性实施例中，也可设置其他结构来开闭第一新风出口124和新风内出口126，例如使两个出口分别设置风门，每个风门独立受控以分别控制第一新风出口124和新风内出口126的开闭，具体不再赘述。In some alternative embodiments, other structures can also be set to open and close the first fresh air outlet 124 and the fresh air inner outlet 126, for example, the two outlets are respectively provided with dampers, and each damper is independently controlled to control the first fresh air outlet 124 respectively. And the opening and closing of outlet 126 in the fresh air, specifically no longer repeat them.
在一些实施例中，如图4至图6所示，外壳100形成有连接其内部空间的出风筒1011，出风筒1011的端部出口构成第一新风出口124，出风筒1011临近端部的筒壁上开设有新风内出口126。如此，使第一新风出口124和新风内出口126相邻且敞开方向垂直，使风门210在大致90°范围内转动即可实现第一新风出口124和新风内出口126的开闭。In some embodiments, as shown in FIG. 4 to FIG. 6 , the casing 100 is formed with an air outlet 1011 connected to its inner space, the end outlet of the air outlet 1011 constitutes the first fresh air outlet 124, and the air outlet 1011 is adjacent to the end. Open the inner outlet 126 of fresh air on the tube wall of the part. In this way, the first fresh air outlet 124 and the fresh air inner outlet 126 are adjacent to each other and the opening direction is perpendicular, and the damper 210 is rotated within approximately 90° to realize the opening and closing of the first fresh air outlet 124 and the fresh air inner outlet 126 .
进一步地，对于壁挂式空调室内机，可使新风风机20临近机壳10的一个横向端面布置(图示为左侧)，使第一新风出口124朝前敞开，使新风内出口126朝机壳10的横向另一端(右端)敞开，以恰好朝机壳10内部吹送新风气流，使新风气流吹向蒸发器。Further, for the wall-mounted air conditioner indoor unit, the fresh air blower 20 can be arranged near a lateral end surface of the casing 10 (the left side is shown in the figure), the first fresh air outlet 124 is opened forward, and the fresh air inner outlet 126 faces the casing. The lateral other end (right end) of 10 is open, so that the fresh air flow is blown toward the inside of the casing 10 so that the fresh air flow is blown to the evaporator.
相应地，机壳10的新风出风口14也朝前敞开，该新风出风口14可命名为前新风出风口14，可使前新风出风口14设置在临近机壳10的横向端面的上角位置，以使其高度更高，使新风气流流出后，送风距离更远。前新风出风口14可由多个孔排列组合而成，以使机壳10更加美观，避免开设一个较大的开口影响机壳10的外观。Correspondingly, the fresh air outlet 14 of the casing 10 is also open to the front. , so that its height is higher, so that after the fresh air flows out, the air supply distance is longer. The front fresh air outlet 14 can be formed by arranging and combining a plurality of holes, so as to make the casing 10 more beautiful, and avoid opening a larger opening to affect the appearance of the casing 10 .
如图1至图3所示，可使机壳10的顶面开设有上新风出风口13，使机壳10的底面开设有下新风出风口15。相应地，新风风机20的外壳100还开设有朝上和朝下的新风出口123、125，以分别与上新风出风口13和下新风 出风口15相接。通过在机壳10的不同表面设置新风出风口，使得新风气流朝不同的方向吹出，以同时对不同区域的气流进行更新，有利于加快室内空气更新速度，使用户能够充分感受到新风的存在。此外，还可在壳体100上开设更多的新风出风口。As shown in FIGS. 1 to 3 , an upper fresh air outlet 13 can be provided on the top surface of the casing 10 , and a lower fresh air outlet 15 can be provided on the bottom surface of the casing 10 . Correspondingly, the housing 100 of the fresh air blower 20 is also provided with upward and downward fresh air outlets 123, 125 to connect with the upper fresh air outlet 13 and the lower fresh air outlet 15 respectively. By arranging fresh air outlets on different surfaces of the casing 10, the fresh air flow blows out in different directions to update the air flow in different areas at the same time, which is beneficial to speed up the indoor air update speed and enables users to fully feel the existence of fresh air. In addition, more fresh air outlets can be provided on the casing 100 .
由于多个新风出口同时出风，使得新风风机20的出风更加顺畅，风力更强。而且，新风出口的数量变多，也会减少每个新风出口的出风阻力。在同等风量下，增加新风出口也将降低了新风风机20的转速，从而使其功耗和噪声更低。Because a plurality of fresh air outlets output air simultaneously, the air output of the fresh air blower 20 is smoother and the wind force is stronger. Moreover, increasing the number of fresh air outlets will also reduce the wind resistance of each fresh air outlet. Under the same air volume, increasing the fresh air outlet will also reduce the rotation speed of the fresh air fan 20, so that its power consumption and noise are lower.

在一些实施例中，如图7所示，新风风机20还包括上侧敞开的水箱171、第二电机172和搅水轮173。水箱171安装于外壳100的内部，搅水轮173在第二电机172的带动下转动，从而搅动水箱171内的水，促进水汽化，从而对新风风机20内的气流进行加湿。搅水轮173具体可包括一与第二电机172连接的转轴1731和从转轴1731的周向不同位置延伸出的多个叶片1732，在转轴1731转动时，各叶片1732拨动水箱171中的水，使水翻滚，以促使水蒸发。水箱171设置在新风风机20的叶轮的上游方向，也就是吸气侧。In some embodiments, as shown in FIG. 7 , the fresh air fan 20 further includes a water tank 171 with an open upper side, a second motor 172 and a water stirring wheel 173 . The water tank 171 is installed inside the housing 100 , and the water stirring wheel 173 rotates under the drive of the second motor 172 , thereby stirring the water in the water tank 171 to promote water vaporization, thereby humidifying the airflow in the fresh air blower 20 . The stirring wheel 173 may specifically include a rotating shaft 1731 connected to the second motor 172 and a plurality of blades 1732 extending from different positions in the circumferential direction of the rotating shaft 1731. When the rotating shaft 1731 rotates, each blade 1732 stirs the water in the water tank 171. , to tumble the water to encourage evaporation. The water tank 171 is arranged in the upstream direction of the impeller of the fresh air blower 20 , that is, on the suction side.
在一些实施例中，如图7所示，外壳100包括蜗壳101和净化壳102，两者贴靠相接且内部空间连通。蜗壳101内设置有新风风机20的叶轮。第一新风出口124以及上新风出口123、下新风出口125开设于蜗壳101上。净化壳102开设有新风进口110，其内设置有净化模块200，以允许从新风进口110吸入的新风气流经净化模块200，被其净化后，再流向叶轮。净化模块200可为过滤模块，以滤除新风气流中的有害杂质。净化模块200也可具有其他处理功能，以对新风气流进行进一步加工处理，使其更加清新健康。In some embodiments, as shown in FIG. 7 , the housing 100 includes a volute 101 and a purification case 102 , which are in contact with each other and communicate with each other in the internal space. The impeller of the fresh air blower 20 is arranged in the volute 101 . The first fresh air outlet 124 , the upper fresh air outlet 123 , and the lower fresh air outlet 125 are opened on the volute 101 . The purification shell 102 is provided with a fresh air inlet 110, and a purification module 200 is arranged therein, so as to allow the fresh air inhaled from the fresh air inlet 110 to flow through the purification module 200, be purified by it, and then flow to the impeller. The purification module 200 can be a filter module to filter out harmful impurities in the fresh air flow. The purification module 200 may also have other processing functions to further process the fresh air flow to make it fresher and healthier.
如图1至图7所示，可使蜗壳101和净化壳102均为扁平状且厚度方向相平行地贴靠相连，两者可采用螺钉实现连接紧固。叶轮可为离心叶轮，蜗壳101的厚度方向(x轴方向)的面对净化壳102的一端设置有吸气口1012。净化壳102面对蜗壳101的一侧敞开，以便罩扣在蜗壳101上，边缘实现密封相接，内部空间连通。净化模块200被净化壳102封盖在内。在叶轮的转动作用下，新风气流从净化壳102的新风进口110进入净化壳102后，流经净化模块200以被其净化，然后从吸气口1012进入蜗壳101。在叶轮的作用下，净化气流沿叶轮径向甩出，然后经第一新风出口124、上新风出口123、 下新风出口125排出蜗壳101。当然，也可使叶轮为轴流叶轮或其他形式的叶轮，在此不再对其具体结构赘述。在了解本公开各个实施例的基础上，本领域技术人员应当易于获知叶轮的结构和安装位置，附图中未做标注。As shown in Fig. 1 to Fig. 7, the volute 101 and the purification case 102 can be made to be flat and connected in parallel in the thickness direction, and the two can be connected and fastened by screws. The impeller may be a centrifugal impeller, and an air suction port 1012 is provided at one end of the volute 101 facing the purification case 102 in the thickness direction (x-axis direction). The side of the purification case 102 facing the volute 101 is open, so that the cover is buckled on the volute 101 , the edges are sealed and connected, and the internal space is communicated. The purification module 200 is covered by the purification case 102 . Under the rotation of the impeller, the fresh air flow enters the purification case 102 from the fresh air inlet 110 of the purification case 102 , flows through the purification module 200 to be purified by it, and then enters the volute 101 from the suction port 1012 . Under the action of the impeller, the purified airflow is thrown out along the radial direction of the impeller, and then discharged from the volute 101 through the first fresh air outlet 124 , the upper fresh air outlet 123 and the lower fresh air outlet 125 . Certainly, the impeller may also be an axial flow impeller or other types of impellers, and its specific structure will not be repeated here. On the basis of understanding various embodiments of the present disclosure, those skilled in the art should easily know the structure and installation position of the impeller, which are not marked in the drawings.
在一些实施例中，如图1至图7所示，净化壳102的周面开设有插口140，以允许净化模块200通过插口140插入净化壳102，以方便净化模块200的安装、清洗和更换。In some embodiments, as shown in FIGS. 1 to 7 , a socket 140 is provided on the peripheral surface of the purification case 102 to allow the purification module 200 to be inserted into the purification case 102 through the socket 140 to facilitate the installation, cleaning and replacement of the purification module 200 .
图8是根据本发明一个实施例的净化壳在转动挡板打开新风进口时的状态示意图；图9是根据本发明一个实施例的净化壳在转动挡板打开回风口时的状态示意图。Fig. 8 is a schematic diagram of the purification case according to an embodiment of the present invention when the baffle is turned to open the fresh air inlet; Fig. 9 is a schematic diagram of the purification case according to an embodiment of the present invention when the baffle is turned to open the air return port.
在一些实施例中，如图8和图9所示，外壳100还限定有朝向机壳10的内部、以用于吸入非新风气流的回风口150，具体可使其开设于净化壳102上。在一种方案中，回风口150位于外壳100的底部且朝下敞开，以吸入机壳10内部的换热气流。在另一种未图示方案中，也可使回风口朝向机壳10的换热进风口11，以吸入未经换热的室内空气。In some embodiments, as shown in FIG. 8 and FIG. 9 , the casing 100 also defines an air return port 150 facing the inside of the casing 10 for inhaling non-fresh air, which can be opened on the purification casing 102 . In one solution, the air return port 150 is located at the bottom of the casing 100 and opens downward to suck in the heat exchange airflow inside the casing 10 . In another solution not shown in the figure, the air return port can also be directed towards the heat exchange air inlet 11 of the casing 10 to suck in the indoor air without heat exchange.
新风风机20配置成允许新风进口110和回风口150同时或择一开启。当空调室内机运行新风模式时，使新风进口110开启，使回风口150关闭，使进入新风风机20的全部为新风，如图8。当室内没有新风需求时，使新风进口110关闭，使回风口150开启，使得新风风机20承担换热气流的吹送工作，以加快室内制冷/制热速度，如图9。当然，也可使新风进口110和回风口150还能同时开启，使新风气流和换热气流在新风风机20内混合，然后吹出。提前完成新风与其他气流的混合过程，加快了室内空气的更新速度。The fresh air fan 20 is configured to allow the fresh air inlet 110 and the return air outlet 150 to be opened simultaneously or alternatively. When the indoor unit of the air conditioner operates in the fresh air mode, the fresh air inlet 110 is opened, the air return port 150 is closed, and all the fresh air entering the fresh air blower 20 is fresh air, as shown in FIG. 8 . When there is no demand for fresh air in the room, the fresh air inlet 110 is closed, and the return air outlet 150 is opened, so that the fresh air fan 20 undertakes the blowing work of the heat exchange airflow to speed up the indoor cooling/heating speed, as shown in Figure 9 . Of course, the fresh air inlet 110 and the return air outlet 150 can also be opened simultaneously, so that the fresh air flow and the heat exchange air flow are mixed in the fresh air blower 20 and then blown out. The mixing process of fresh air and other airflows is completed in advance, which speeds up the renewal speed of indoor air.
总之，回风口150的设置极大丰富了新风风机20的功能，设计非常巧妙。In a word, the setting of the return air outlet 150 greatly enriches the functions of the fresh air blower 20, and the design is very ingenious.
如图8和图9所示，在一些实施例中，使得新风进口110和回风口150相邻。新风风机20还包括转动挡板190和第三电机180。转动挡板190的一端可枢转地安装于新风进口110与回风口150之间，以转动至封闭新风进口110、打开回风口150的位置，如图9；或转动至封闭回风口150、打开新风进口110的位置，如图8。第三电机180配置成受控地驱动转动挡板190转动。可以理解的是，当转动挡板190转动至图8和图9的中间状态时，新风进口110与回风口150均被开启。该实施例仅通过设置一个转动挡板190和一个第三电机180就可控制新风进口110与回风口150，结构非常简单实用。As shown in FIG. 8 and FIG. 9 , in some embodiments, the fresh air inlet 110 and the return air outlet 150 are adjacent to each other. The fresh air fan 20 also includes a rotating baffle 190 and a third motor 180 . One end of the rotating baffle 190 is pivotably installed between the fresh air inlet 110 and the air return port 150, so as to rotate to the position of closing the fresh air inlet 110 and opening the return air port 150, as shown in Figure 9; The position of the fresh air inlet 110 is shown in Figure 8. The third motor 180 is configured to drive the rotating baffle 190 to rotate in a controlled manner. It can be understood that when the rotating baffle 190 is rotated to the intermediate state shown in FIG. 8 and FIG. 9 , both the fresh air inlet 110 and the return air outlet 150 are opened. In this embodiment, the fresh air inlet 110 and the return air outlet 150 can be controlled only by setting a rotating baffle 190 and a third motor 180, and the structure is very simple and practical.
在一些替代性实施例中，也可利用平移的挡板来控制新风进口110和回风口150的开闭，还可以设置两个第三电机和两个挡板分别控制新风进口110和回风口150的开闭，具体不再赘述。In some alternative embodiments, a translational baffle can also be used to control the opening and closing of the fresh air inlet 110 and the return air outlet 150, and two third motors and two baffles can also be set to control the fresh air inlet 110 and the return air outlet 150 respectively. The opening and closing, the details will not be repeated.
