图1至图13为本申请窗式空调器的实施例附图。本申请所提供的窗式空调器的实施例中，所述窗式空调器是将室内机及室外机一体式制成，窗式空调器整机安装在建筑的窗框上，可实现对室内环境制冷或制热。所述窗式空调器还能够将室外的新风空气引入到室内，且其引入新风的风速较高，新风风量较大。下文将对所述窗式空调器的实施例进行介绍说明。
请参阅图1至图3，在本申请的窗式空调器100的一实施例中，窗式空调器100包 括机壳110和新风壳200，机壳110包括室内部分101和室外部分102，新风壳200安装于机壳110内。新风壳200构造有位于室外部分102的新风入口201，以及位于室内部分101的新风出口202，新风壳200的内部形成有将新风入口201和新风出口202连通的新风风道，所述新风风道适用于将室外环境的空气送入室内环境。其中，所述新风风道包括与新风入口201对应的进风段230，以及与新风出口202对应的出风段240，出风段240的通风横截面面积小于进风段230的通风横截面面积。
具体说来，机壳110具有前表面、背面、侧面及顶面。顶面可以是一整个呈水平状设计的平面，也可以由一平面和与所述平面的前端连接的倾斜面组成。在此，机壳110的前表面设有室内进风口103，机壳110的顶面前端(即倾斜面)设有室内出风口104。机壳110的背面设有室外进风口，机壳110的侧面设有室外出风口。
窗式空调器100还包括室内风道壳160和室外风道壳170。其中，所述室内风道壳160安装于机壳110的室内部分101，用以形成将室内进风口103和室内出风口104连通的室内风道。室外风道壳170安装于机壳110的室外部分102，用于形成将室外进风口和室外出风口连通的室外风道。窗式空调器100还包括室内换热器120和室外换热器130。其中，室内换热器120安装于机壳110的室内部分101，并与室内进风口103对应；室外换热器130安装于机壳110的室外部分102，并与所述室外进风口对应。窗式空调器100还包括室内风机140和室外风机150。其中，室内风机140安装于所述室内风道，用以驱动空气从室内风口进入到室内风道，而后与室内换热器120换热后从室内出风口吹出。室外风机150安装于所述室外风道，用以驱动空气从室外风进入到室外风道，而后与室外换热器130换热后从室外出风口吹出。
对于新风壳200而言，新风壳200可以安装在机壳110的左侧或右侧，新风壳200自机壳110的室外部分102延伸至其室内部分101。当窗式空调器100开启新风模式时，室外环境的新风空气从新风壳200的新风入口201进入，而后依次经新风风道的进风段230、出风段240流动到新风出口202，最后从新风出口202吹出。通过合理设计新风壳200的新风出口202的位置，可以使得从新风出口202吹出的 空气可以直接从机壳110的室内进风口103吹出到室内房间；或者，也可以从新风出口202吹出的空气吹向室内换热器120的进风侧，经室内换热器120换热或除湿后从室内出风口104吹出到室内环境。
本申请的技术方案，通过将所述新风风道的出风段240的通风横截面面积小于其进风段230的通风横截面面积，以使得气流在从进风段230进入到出风段240的过程中，气流被挤压压缩到出风段240内，出风段240内的新风空气被挤压使得气压升高，气压较高的新风空气快速流向新风出口202，使得新风获得较高的风速，进而快速从新风出口202吹出，有效增大新风风量。至于新风壳200的形状结构则不设限定，要求所述新风风道的出风段240的通风横截面面积小于其进风段230的通风横截面面积即可。具体在后文还有详细介绍。
请参阅图1、图2及图8，在一实施例中，新风壳200吹出的新风可以直接从室内风道经室内出风口104吹出，也可以先吹直室内换热器120的进风侧、以由室内换热器120换热后从室内风道经室内出风口104吹出，还可以直接从室内进风口103直接吹出。在本实施例中，窗式空调器100还包括安装于室内部分101的室内换热器120；出风段240包括与进风段230连接并沿水平向延伸的第一出风部241，以及与第一出风部241连接并沿纵向延伸的第二出风部242。其中，第一出风部241的部分位于室内换热器120的下方，第二出风部242的部分位于室内换热器120进风侧。
具体说来，出风段240的第一出风部241和第二出风部242大致呈L形设置，新风壳200的新风出口202与第二出风部242对应。由于新风壳200的对应第二出风部242的部分位于室内换热器120进风侧，从而使得从新风壳200的新风出口202吹出的新风可以直接从窗式空调器100的前侧吹出，或经室内换热器120的进风侧通过室内换热器120而进入到室内风道中，进而从室内出风口104吹出。
此外，由于出风段240的通风横截面面积较小，从而新风壳200的对应出风段240的部分体积也相应可设计得较小，进而将容易安装到室内换热器120的下方，占用空间较小，从而无需在室内风机140和室内换热器120之间预留供新风壳200安装的位置。
进一步地，机壳110于室内部分101的正面构造有室内进风口103，并在对应室 内部分101的顶面构造有室外出风口；新风壳200的新风出口202构造于所述第二出风部242的侧壁上，新风出口202适用于向室内换热器120的进风侧吹出或向室内进风口103送风。
在一实施例中，为方便安装新风壳200，新风壳200的对应第一出风部241的部分呈扁平状设置，以使得新风壳200的对应第一出风部241的部分厚度较小，从而使得该新风壳200的对应第一出风部241的部分可嵌入至机壳110的底盘111和室内换热器120的底部之间。此外，这样设计还可以使得第一出风部241相较于进风段250狭窄，有助于增大第一出风部241的气压，进而可以驱动气流加速吹出。
请参阅图1、图2及图8，基于上述任意一实施例，新风壳200内新风风道的进风段250的形状，可以是通风横截面保持不变的直筒状，也可以是通风横截面渐变的非规则状。在此考虑到，如果进风段250呈直筒状设计，而出风段240的与该进风段250连接的第一出风部241呈扁平状设计，那么在进风段250和出风段240之间会出现横截面面积突变(类似于横截面面积从进风段250到出风段240断崖式变小)，在该横截面面积突变的位置会形成较大的风阻，不利于气流流动。
鉴于此，进风段250可选采用通风横截面渐变的非规则状设计。在此可选地，进风段250包括呈筒状设置的进风部231，以及连接进风部231和出风段240的导风部252，导风部252的通风横截面自进风部231向出风段240呈渐缩状设置。
具体说来，空气从进风部231通过并进入到导风部252，而后由导风部252引导进入到出风段240，最后从出风段240的新风出口202吹出。由于导风部252的通风横截面面积自进风部231向出风段240呈渐缩状设置，从而可避免在进风段250和出风段240的第一出风部241之间出现横截面面积突变，进而避免在该位置形成较大的风阻，使得气流可以顺利从进风段250进入出风段240。
进一步地，新风壳200包括底壳210及盖合底壳210的壳盖220，壳盖220的顶壁在对应导风部252的部分构造有导风壁221，导风壁221自上向下呈弧形设置，以使导风部252呈渐缩状设置。此外，导风壁221呈弧形设计，也可以使得导风壁221具有较佳的强度，不易发生变形。
请参阅图8至图10，为了增强导风壁221的强度，还可以在壳盖220在对应出风 段240的部分朝上凸设形成有凸包222，凸包222靠近导风壁221，在壳盖220在凸包222的远离导风部232的一侧形成有供窗式空调器100的室内换热器120对应安装的安装槽223。
具体说来，凸包222靠近导风壁221，从而凸包222可作为导风壁221的加强结构，用以强力支撑导风壁221，使得导风壁221不易发生变形。凸包222由新风壳200的壳盖220局部向上隆起形成，从而在壳盖220在凸包222的内侧形成有扩容凹槽，所述扩容凹槽与导风部232对接，从而扩容凹槽形成新风风道的一部分。该扩容凹槽的存在，可以弥补底壳210的第一凹部占用的风道空间，从而使得出风段240前后的通风横截面面积基本一致。并且，该扩容凹槽位于进风段230和出风段240之间转折位置，从而可以增大进风段230和出风段240之间转折位置的风道空间，有助于减小该转折位置对气流流动的阻力，使得气流可以顺利从进风段230进入到出风段240，增大风量；并且，还可以避免气流在转折碰撞到风道内壁，进而避免产生较大的噪音。
在一实施例中，窗式空调器100还包括新风风机300，新风风机300可以安装在新风壳200的外侧，也可以安装在新风壳200的内侧。具体在此，新风风机300安装在新风壳200的内侧，并且位于于新风壳200的进风段230的进风部231，以使得新风风机300在新风壳200的进风段230形成有较大的气压，从而驱动更多的新风空气进入新风壳200内，增大新风风量。
请参阅图5至图7，基于上述任意一实施例，由于新风壳200安装于底盘111上，而底盘111的上表面形状通常不规则，在底盘111上形成有凹凸不平的表面，故为确保新风壳200安装稳定，可选将新风壳200的底壳210和底盘111形状大致适配，具体可依据底盘111的凹凸位置进行相应设计。
请参阅图8至图10，在一实施例中，底盘111构造形成有与机壳110的室内部分101对应的接水槽11，新风壳200的底壳210在对应接水槽11的位置形成有凸起部211，凸起部211与接水槽11对应配合。其中，接水槽11对应供室内风道壳160和室内换热器120安装。新风壳200的底壳210通过凸起部211对应与该接水槽11的一端配合，该凸起部211与接水槽11的底面形成有面接触，增了新风壳200的底壳210与接水槽11的配合面积，从而使得新风壳200不易在该接水槽11处发生晃 动，增强新风壳200安装的稳定性。
进一步地，底盘111构造形成有与机壳110的室外部分102对应的沉槽14，底盘111在沉槽14和接水槽11之间形成有第一凸台12，新风壳200的底壳210在对应第一凸台12对应配合。通过第一凸台12将接水槽11和沉槽14分隔开，使得沉槽14的水不易溢流回到接水槽11中，减少避免溢流到室内房间。
在此考虑到，如果新风壳200的对应进风段230的部分与沉槽14对应配合，那么，沉槽14中的水可能会从新风壳200的新风入口201进入到新风风道中，进而导致新风过于潮湿或出现吹水现象。
请参阅图8至图11，为避免上述情况的出现，可在底盘111在沉槽14的一侧和第一凸台12之间还构造有第二凸台13，第二凸台13高于第一凸台12，新风壳200的底壳210在对应沉槽14的位置形成有第二凹部213，第二凹部213由第二凸台13支撑，而将新风壳200的底壳210与沉槽14的槽底间隔开。
具体说来，通过第二凸台13支撑新风壳200的第二凹部213，相当于通过第二凸台13将新风壳200的新风入口201抬高，使得沉槽14中中的水不易从新风壳200的新风入口201进入到新风风道中，进而避免新风过于潮湿或出现吹水现象。
综上所述，底盘111的接水槽11和第一凸台12、第二凸台13组合大致呈阶梯状设置；相应地，将新风壳200的底壳210上的凸起部211和第一凹部212、第二凹部213组合也大致呈阶梯状设计，从而使得新风壳200可与底盘111形状基本适配。
进一步地，考虑到新风壳200的新风入口201需要靠近室外进风口，故新风壳200的靠近新风入口201的一端会从沉槽14上方向室外进风口延伸，也就是说，新风壳200的第二凹部213部分会悬空于沉槽14上方，这样会存在新风壳200向沉槽14倾倒的可能。为避免这种情况发生，可在第二凹部213的下表面凸设有支撑架214，支撑架214适用于与沉槽14的槽底坻持，而支撑新风壳200，从而使得新风壳200不易向沉槽14倾倒，大大提高新风壳200安装的稳定性。
请参阅图6至图8，基于上述任意一实施例，窗式空调器100还包括安装于接水槽11的接水盘400，接水盘400适用于承接室内换热器120产生的冷凝水。在此，可将接水盘400的一端延伸至新风壳200的上方，以避免冷凝水直接落入到新风 壳200上，打湿新风壳200。可选地，并与新风壳200的上方的上表面对应配合。例如，新风壳200的壳盖220凸设有凸包222，相应地，接水盘400的底面构造有供凸包222对应容置的容置槽。
由于接水盘400的一端延伸至新风壳200的上方，如果接水盘400的远离新风壳200的一端悬空，则会使得接水盘400晃动不稳定。为解决该问题，窗式空调器100还包括设置在接水槽11内的垫板，所述垫板位于新风壳200的一侧，并与新风壳200的位于接水槽11内的部分平齐，以与该新风壳200的位于接水槽11内的部分配合支撑接水盘400。所述垫板可以是泡沫或海绵等具有弹性或柔性的材料，这样可以与接水盘400的底面接触更紧密，稳定性更高。
进一步地，为了将接水盘400的水排出，在接水盘400构造有排水槽410，所述排水槽410自接水盘400朝向沉槽14延伸，以用于向底盘111的沉槽14排出。最后通过沉槽14向室外环境排出。
请参照图3和图12，基于上述任意一实施例，窗式空调器的机壳在其壳体112的正面设有室内进风口103。在此，所述壳体112的正面应当指的是窗式空调器面向用户的一面。窗式空调器的室内侧换热器120包括第一室内换热器121及第二室内换热器122，窗式空调器具有恒温除湿模式，在恒温除湿模式下，第一室内换热器121及第二室内换热器122的其中一者处于制热模式，另一者处于制冷模式。
在本实施例中，通过使得室内侧换热器120具有第一室内换热器121及第二室内换热器122，且在恒温除湿模式下，使得第一室内换热器121及第二室内换热器122的其中一者处于制热模式，另一者处于制冷模式。经过室内侧换热器120的气流能够同时被加热和除湿，经过加热和除湿后的混合风温度适宜，不会有凉风感受，往复循环后不仅能将所有的室内风及新风重新除湿，且使得窗式空调器在除湿模式下整个室内温度不会下降，能够达到对全屋恒温除湿的目的。同时，除湿时能够充分利用室内侧换热器120，不用另外设置新风冷凝器及新风蒸发器，则大大降低了制造成本。
在一实施例中，请参照图3和图12，第一室内换热器121与第二室内换热器122沿室内侧风道210的进风方向层叠设置。当第一室内换热器121及第二室内换热 器122沿室内侧风道210的进风方向层叠设置时，从室内进风口103进入的室内风或新风，先经过第一室内换热器121除湿/加热，再经过第二室内换热器122加热/除湿，室内风机将经过加热除湿后的气流从室内出风口送入室内，实现全屋恒温除湿。使得第一室内换热器121和第二室内换热器122沿进风方向层叠设置，则从室内进风口103吹出的全部气流能够被同时加热，随后同时被除湿，从而无需使得加热和除湿分为两股不同的气流，减少了混合步骤，使得从室内出风口吹出的气流温度及湿度更加均匀、舒适。
在另一实施中，请参照图13，第一室内换热器121及第二室内换热器122在垂直室内侧风道210的进风方向上呈并排设置，以使从室内进风口103进入的气流一部分吹向第一室内换热器121，另一部分吹向第二室内换热器122。
在本实施例中，室内进风口103的进风方向通常为前后方向，则垂直于室内进风口103的进风方向的方向可为左右和上下方向。如此，第一室内换热器121及第二室内换热器122可以呈上下排布或左右排布，从室内进风口103进入的新风或室内风，部分经过第一室内换热器121加热/除湿，另一部分经过第二室内换热器122除湿/加热，然后在室内侧风道210内混合后形成温度适宜的干燥气流，再由室内风机将恒温的干燥气流从室内出风口送入室内，实现全屋恒温除湿。当第一室内换热器121及第二室内换热器122呈上下排布设置时，可以仅通过设置一个室内换热器，而将其上部划分为第一室内换热器121，将其下部划分为第二室内换热器122，通过控制阀控制上部换热器及下部换热器中的其中一者处于制热状态，另一者处于制冷状态。如此，能够大大减小室内侧换热器120的占用空间，从而使得整体结构更加紧凑，整机体积更小。通过使得第一室内换热器121及第二室内换热器122沿上下或左右排布，能够大大减小室内侧换热器120的厚度，充分利用壳体112高度方向的空间，从而减少室内侧换热器120的占用空间，减小整机体积和重量。
在一实施例中，如图18所示，窗式空调器还包括室外换热器130、冷媒循环管路、第一阀510及第二阀520，窗式空调器的压缩机180的冷媒出口设置有排出管181，冷媒入口设置有吸入管182，排出管181、室外换热器130、第一室内换热器121、第二室内换热器122、吸入管182通过冷媒循环管路依次连通，第一阀51 0串接在室外换热器130与第一室内换热器121之间的冷媒循环管路上，第二阀520串接在第一室内换热器121与第二室内换热器122之间的冷媒循环管路上。
在本实施例中，压缩机180可以为变频式压缩机180或定频式压缩机180。通过使得压缩机180为变频式压缩机180，能够更佳的实现制冷及恒温除湿双系统，节约了一个压缩机180，从而使得整体结构更加简单，降低成本和功率，大大提高了能效。第一阀510及第二阀520可以为电磁阀、电子膨胀阀或节流阀，能够控制其所在配管的通断或流量。通过设置第一阀510及第二阀520，能够控制冷媒是否流入第一室内换热器121及第二室内换热器122，从而控制第一室内换热器121及第二室内换热器122是否参与制冷或制热。
当需要开启除湿模式时，压缩机180流出的高温冷媒进入到室外换热器130(冷凝器)，从而室外换热器130出来的高温冷媒到达第一阀510，此时第一阀510可以全部或大部分打开，让室外换热器130的温度等于或略小于第一室内换热器121的温度，此时第一室内换热器121为冷凝器，起到加热气流的作用，然后流出第一室内换热器121的次高温冷媒到达第二阀520，第二阀520部分打开，起到毛细管节流的作用，节流后冷媒变为低温冷媒，流过第二室内换热器122，此时第二室内换热器122为蒸发器，起到降温的作用，也即除湿，从第二室内换热器122流出的冷媒再回到压缩机180。如此，新风和室内风混合后部分经过第一室内换热器121加热，部分经过第二室内换热器122降温除湿，进入室内侧风道210混合后形成温度适宜的干燥气流，随后由室内出风口吹出，从而达到室内即除湿又不会吹冷风的目的，且除湿效果更佳。当然，第一室内换热器121也可以作为蒸发器，则第二室内换热器122作为冷凝器，同样可以实现恒温除湿的目的。
当不需要除湿，仅需开启全制冷模式时，使得压缩机180流出的高温冷媒进入到室外换热器130(冷凝器)，从而室外换热器130出来的高温冷媒到达第一阀510，此时第一阀510小部分打开起到毛细节流的作用，让第一室内换热器121的温度大大小于室外换热器130的温度，此时第一室内换热器121为蒸发器，起到降温的作用，然后流出第一室内换热器121的低温冷媒到达第二阀520，第二阀520完全或大部分开启，起到完全通过或者再节流的作用，通过第二阀520的冷媒流过第二室内换热器122，此时第二室内换热器122为蒸发器，起到二次降温的 作用，从第二室内换热器122流出的冷媒再回到压缩机180。如此，新风和室内风混合后经过第一室内换热器121降温，然后经过第二室内换热器122二次降温，进入室内侧风道210后由室内出风口吹出，从而能达到室内快速降温的目的。
在一实施例中，如图19所示，冷媒循环管路包括连接排出管181与室外换热器130的第一配管610，以及连接吸入管182与第二室内换热器122的第二配管620。窗式空调器还包括切换装置700，切换装置700串接于第一配管610及第二配管620上，切换装置700具有第一切换状态及第二切换状态。在第一切换状态下，连接于切换装置700两端的第一配管610导通，连接于切换装置700两端的第二配管620导通。在第二切换状态下，排出管181和切换装置700之间的第一配管610与切换装置700和第二室内换热器122之间的第二配管620导通，室外换热器130和切换装置700之间的第一配管610与吸入管182和切换装置700之间的第二配管620导通。
在本实施例中，可以理解的是，窗式空调器还具有控制器，控制器与第一阀510、第二阀520及切换装置700均电连接，从而控制切换装置700的切换状态及各个阀的开关及开度。切换装置700可以为四通阀或其他使得冷媒不会同时进入室外换热器130和第二室内换热器122的切换装置700。通过切换装置700，能够使得空调器的功能增加。可以理解的是，切换装置700串接在第一配管610及第二配管620上，也即切换装置700的两端连通第一配管610，两端连通第二配管620。
在切换装置700处于第一切换状态时，压缩机180的排出管181流出的高温冷媒通过第一配管610流向室外换热器130，然后依次流入第一室内换热器121及第二室内换热器122，最后经第二配管620及吸入管182流回压缩机180。通过控制第一阀510及第二阀520的开度，能够控制第一室内换热器121为制冷状态或制热状态，从而能够控制整个系统处于恒温除湿模式或全制冷系统。第一阀510及第二阀520控制第一室内换热器121是处于制冷状态或制热状态，与上述没有切换状态的实施例相似，在此不做赘述。
在切换装置700处于第二切换状态时，压缩机180的排出管181流出的高温冷媒通过第一配管610及第二配管620流入第二室内换热器122，随后流向第一室内换 热器121及室外换热器130，最后通过第一配管610、第二配管620及吸入管182流回压缩机180。可以通过控制第一阀510及第二阀520的开度，进而控制第一室内换热器121是处于制冷状态或制热状态，从而控制整个系统是处于恒温除湿模式还是处于全制热状态。
当开启全制热模式时，切换装置700处于第二切换状态，压缩机180的排出管181流出的高温冷媒通过第一配管610及第二配管620流入第二室内换热器122，此时第二室内换热器122起到冷凝器加热的作用，从而第二室内换热器122出来的高温冷媒到达第二阀520，此时第二阀520全部打开，高温冷媒继续流出到第一室内换热器121，第一室内换热器121起到再次加热的作用，次高温冷媒到达第一阀510后，可使得第一阀510起到毛细管节流的作用，节流后冷媒变为低温冷媒，流经室外换热器130后回到压缩机180。如此，能实现室内快速制热的目的。
