本申请基于申请号为202110611187.9、申请日为2021年06月01日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及空调领域，具体地，涉及壁挂式空调器。
背景技术
相关技术中，壁挂式空调器的进风口设在其顶部，为了满足顶部进风的需求，壁挂式空调器必须与室内的顶壁间隔开较大的距离，从而导致室内的空间利用率较低，室内空间显得比局促。而且，相关技术中的壁挂式空调器存在换热效率低的缺陷。
发明内容
本发明旨在至少在一定程度上解决相关技术中的技术问题之一。为此，本发明的实施方式提出一种壁挂式空调器。
本发明实施方式的壁挂式空调器包括机壳、电控部件和换热器，所述机壳内具有风道，所述换热器设置在所述风道内，所述风道包括相连的进风段和出风段，所述风道具有进风口和出风口，所述进风口的至少一部分位于所述机壳的正面，所述电控部件安装在所述进风段的上方。
根据本发明的壁挂式空调器的进风口的至少一部分位于机壳的正面，可以使环境中的空气(进风)从机壳的大体前方进入到风道内。例如，环境中的空气(进风)可以从机壳的正前方进入到风道内，也可以从机壳的前上方进入到风道内，还可以从机壳的前下方进入到风道内。此外，环境中的空气可以从机壳的正前方、前上方和前下方中的至少两个方向进入到风道内。
也就是说，环境中的空气可以不必从机壳的正上方进入到风道内。这样可以极大地减小或消除壁挂式空调器与室内的顶壁之间的距离，可以提高室内的空间利用率，尤其是对于高度较低的室内(房间)，可以有效地减小或消除室内空间的局促感。
因此，本发明实施例的壁挂式空调器对安装空间的要求非常低，安装空间只要能够容纳下壁挂式空调器即可，可以不必在壁挂式空调器的上方留出进风空间，能够扩大壁挂式空调器的适用范围。
在一些实施方式中，进风口位于正面的部分，相对于竖直面，朝墙面(可理解为安装面)斜向上倾斜。这样，当用户站立在室内的地面上时，用户无法通过进风口看到机壳(壁挂式空调器)的内部，机壳(壁挂式空调器)的内部结构未暴露给用户，这样可 以提高用户的视觉舒适度。
而且，在顶部进风的场景下，顶部空间往往是有限的，比较狭窄的，这样进风量会因为顶部空间狭窄而受限。本申请的技术方案中，使进风口的至少一部分位于机壳的正面，可以使经由进风口进入到风道内的空气直接流过换热器，以便与换热器充分地进行换热。也就是说，壁挂式空调器的进风量可以不受顶部狭窄空间的限制，从机壳的正面进风，可以有效地增大进风量，也能够显著地提高流过换热器的空气的流量，可以极大地提高换热器的换热效率。
本申请中，进风口的至少一部分位于机壳的正面，无需在进风口的下方设置成大体倒V形的换热器，也就无需在成大体倒V形的换热器的下端部处设置宽度大于或等于大体倒V形的换热器的宽度的接水盘，以便避免因接水盘遮挡而造成换热器的一部分基本不与空气进行换热。进风口的至少一部分位于机壳的正面，使得接水盘可以不阻止气流流向换热器，例如接水盘可以不经过气流流向换热器的流路，这样可以极大地提高换热器的换热效率。可选地，接水盘设置在换热器的下方。
因此，本发明实施例的壁挂式空调器具有便于安装、提高室内的空间利用率、适用范围广、换热效率高的优点。
此外，本发明实施方式提供的壁挂式空调器将电控部件安装在了风道的进风段的上方，使电控部件的安装不占用机身的长度方向上的空间，缩短了机身的长度，还提高了壁挂式空调器的空间利用效率和集成度，使壁挂式空调器的结构更加紧凑、合理。并且电控部件的安装不会挤占换热器的有效进风面，不会牺牲换热器的换热效率，本发明实施例提供的壁挂式空调器的性能得到改善。
由此，本发明实施方式提供的壁挂式空调器具有机体内部空间利用率高、结构紧凑、长度小、测试维修方便的优点。
在一些实施方式中，所述进风段从所述出风段水平或倾斜地向前延伸。
在一些实施方式中，所述进风段的风道壁包括第一进风板和第二进风板，所述出风段的风道壁包括第一出风板和第二出风板，所述电控部件与所述第一进风板和/或所述第一出风板相连。
在一些实施方式中，所述第一进风板和所述第一出风板相连，所述第二进风板和所述第二出风板相连。
在一些实施方式中，所述电控部件与所述第一进风板和/或所述第一出风板之间设有保温层。
在一些实施方式中，所述电控部件包括：防护外壳，所述防护外壳包括盒体和盒盖，所述盒体和所述盒盖相连以限定出密封的防火腔；电器元件，所述电器元件位于所述防火腔内。
在一些实施方式中，所述电器元件包括主板和元器件，所述主板与所述盒体的底板平行且与所述底板之间具有间隔，所述元器件安装在所述主板的远离所述底板的面上。
在一些实施方式中，所述机壳包括顶板，所述风道位于所述顶板下方，所述电控部 件位于所述顶板的上方，或者所述电控部件的上表面与所述顶板平齐，或者所述电控部件位于所述顶板和所述风道之间
在一些实施方式中，所述机壳内具有安装空间，所述安装空间位于所述机壳内的后上方，所述电控部件设在所述安装空间内。
在一些实施方式中，所述进风段的中心线和所述出风段的中心线之间的夹角大于或等于10度且小于或等于85度。
本发明的附加方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本发明的实践了解到。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
本发明是基于发明人对以下事实和问题的发现和认识做出的：
相关技术中，如图4所示，壁挂式空调器1′的进风口设在其顶部，壁挂式空调器1′的顶部必须与室内顶壁3之间间隔较大的距离，以构成进风空间，从而壁挂式空调器1′无法与室内顶壁3紧贴设置。壁挂式空调器1′的换热器10′围绕贯流风轮20′设置。具体地，换热器10′成大体倒V形的第一部分11′位于贯流风轮20′上方，换热器10′的第二部分12′位于贯流风轮20′前方。
第一部分11′的后下端部111′的下方设有接水盘30′。接水盘30′在上下方向上与第一部分11′的后下端部111′相对，接水盘30′位于第一部分11′的后下端部111′与贯流风轮20′之间。发明人认识到，第一部分11′的后下端部111′被接水盘30′遮挡，进而导致第一部分11′的后下端部111′基本不与空气进行换热，导致浪费，降低了换热效率。
第二部分12′与壁挂式空调器1′的前面板40′之间限定出进风风道50′。但是，发明人认识到，由于壁挂式空调器1′在前后方向上的大部分空间被换热器10′、贯流风轮20′和蜗壳60′占据，因此导致进风风道50′比较狭窄，即流过进风风道50′的空气流量较小，由此导致第二部分12′的换热效率较低。
发明人还发现：相关技术中，壁挂式空调器的电控部件安装在机身长度方向的侧部(例如左侧部和/或右侧部)，通常存在两种情况：一种是电控部件与分配器等管路系统同侧布置，另一种是电控部件与分配器等管路系统分别安装在机身长度方向的两个侧部。然而，无论是哪种方式，电控部件均会占用机身长度方向上的空间，使机身长度被拉长。在机身长度不变的情况下，若将电控部件与管路同侧布置会压缩管路空间，增加与管路刮碰的隐患。若将电控部件安装在换热器长度方向的侧部，还会挤占换热器有效进风面，进而牺牲换热器的换热效率。并且，将电控部件安装在机身长度方向的侧部，在对其进行维修、拆装时都要把机壳拆除，增加维修难度。
下面根据图1至图3描述本发明的实施例的壁挂式空调器1。如图1所示，壁挂式空调器1包括机壳10、换热器20、风道30和电控部件90。其中风道30设在机壳10内，换热器20位于风道30内。风道30具有进风口311和出风口312，风道30包括相连的进风段313和出风段314，其中进风口311位于进风段313，出风口312位于出风段314。电控部件90安装在进风段313的上方。
进风口311的至少一部分位于机壳10的正面11。机壳10的正面11为机壳10的能够被水平向后的视线所看到的表面，即能够被水平向后的视线所看到的机壳10的表面为机壳10的正面11。例如，当观察者的眼睛和机壳10大体位于同一水平高度、且观察者位于机壳10的前方时，观察者能够看到的机壳10的表面为机壳10的正面11。
前后方向如图1中的箭头A所示，上下方向如图1中的箭头B所示。例如，壁挂式空调器1可以安装在墙面2上。沿水平方向远离墙面2的方向为正前，沿水平方向远离墙面2的方向为正后。
根据本发明的壁挂式空调器的进风口的至少一部分位于机壳的正面，可以使环境中的空气(进风)从机壳的大体前方进入到风道内。例如，环境中的空气(进风)可以从机壳的正前方进入到风道内，也可以从机壳的前上方进入到风道内，还可以从机壳的前下方进入到风道内。此外，环境中的空气可以从机壳的正前方、前上方和前下方中的至少两个方向进入到风道内。
也就是说，环境中的空气可以不必从机壳的正上方进入到风道内。这样可以极大地减小或消除壁挂式空调器与室内的顶壁之间的距离，可以提高室内的空间利用率，尤其 是对于高度较低的室内(房间)，可以有效地减小或消除室内空间的局促感。
因此，本发明实施例的壁挂式空调器对安装空间的要求非常低，安装空间只要能够容纳下壁挂式空调器即可，可以不必在壁挂式空调器的上方留出进风空间，能够扩大壁挂式空调器的适用范围。
在一些实施方式中，进风口311位于正面的部分，相对于竖直面，朝墙面2(可理解为安装面)斜向上倾斜。这样，当用户站立在室内的地面上时，用户无法通过进风口311看到机壳10(壁挂式空调器1)的内部，机壳10(壁挂式空调器1)的内部结构未暴露给用户，这样可以提高用户的视觉舒适度。
而且，在顶部进风的场景下，顶部空间往往是有限的，比较狭窄的，这样进风量会因为顶部空间狭窄而受限。本申请的技术方案中，使进风口的至少一部分位于机壳的正面，可以使经由进风口进入到风道内的空气直接流过换热器，以便与换热器充分地进行换热。也就是说，壁挂式空调器的进风量可以不受顶部狭窄空间的限制，从机壳的正面进风，可以有效地增大进风量，也能够显著地提高流过换热器的空气的流量，可以极大地提高换热器的换热效率。
本申请中，进风口的至少一部分位于机壳的正面，无需在进风口的下方设置成大体倒V形的换热器，也就无需在成大体倒V形的换热器的下端部处设置宽度大于或等于大体倒V形的换热器的宽度的接水盘，以便避免因接水盘遮挡而造成换热器的一部分基本不与空气进行换热。进风口的至少一部分位于机壳的正面，使得接水盘可以不阻止气流流向换热器，例如接水盘可以不经过气流流向换热器的流路，这样可以极大地提高换热器的换热效率。可选地，接水盘设置在换热器的下方。
因此，本发明实施例的壁挂式空调器具有便于安装、提高室内的空间利用率、适用范围广、换热效率高的优点。
此外，本发明实施例提供的壁挂式空调器将电控部件安装在了风道的进风段的上方，使电控部件的安装不占用机身的长度方向上的空间，缩短了机身的长度，还提高了壁挂式空调器的空间利用效率和集成度，使壁挂式空调器的结构更加紧凑、合理。并且电控部件的安装不会挤占换热器的有效进风面，不会牺牲换热器的换热效率，本发明实施例提供的壁挂式空调器的性能得到改善。
由此，本发明实施例提供的壁挂式空调器具有空间利用率高、结构紧凑、性能好、长度小、测试维修方便的优点。
下面结合图1和图2详细描述本发明提供的具体实施例。在一些实施例中，壁挂式空调器1可以安装在室内的墙面2。
如图1和图2所示，壁挂式空调器1包括机壳10、换热器20、设在机壳10内的风道30、设在风道30中的风轮40以及电控部件90。机壳10包括前板111，进风口311设在前板111上。
在一些实施例中，机壳10在安装在墙面2时，机壳10的顶面与室内的顶壁3之间的距离小于或等于20厘米。换言之，机壳10与室内的顶壁3在上下方向上的最小距离 小于或等于20厘米。由此可以进一步提高室内的空间利用率。
可选地，机壳10的顶面与室内的顶壁3之间的距离小于或等于15厘米。或者，机壳10的顶面与室内的顶壁3之间的距离小于或等于10厘米。或者，机壳10的顶面与室内的顶壁3之间的距离小于或等于8厘米。或者，机壳10的顶面与室内的顶壁3之间的距离小于或等于5厘米。或者，机壳10的顶面与室内的顶壁3接触，即机壳10的顶面与室内的顶壁3之间的距离等于0厘米。由此可以进一步提高室内的空间利用率。
风道30包括相连的进风段313和出风段314，进风段313限定出了进风通道3136，出风段314限定出了出风通道3143。风道30的进风口311位于进风通道3136的一端，风道30的出风口312位于出风通道3143的一端。电控部件90安装在进风段313的上方，电控部件90的安装不占用机身的长度方向上的空间，缩短了机身的长度，还提高了壁挂式空调器1的空间利用效率和集成度，使壁挂式空调器1的结构更加紧凑、合理。
换热器20位于进风通道3136内且设在进风口311处，换热器20与进风口311相对，以便对从进风口311处进入进风通道3136中的空气进行换热。风轮40的一部分位于进风通道3136中，风轮40的另一部分位于出风通道3143中。风轮40用于产生排风力，使空气从进风口311进入进风通道3136后经过风轮40进入出风通道3143，最后从出风口处排出。在风道30内设置风轮40，可以提高流过换热器20的空气的流量和流速，以便进一步提高换热器20和壁挂式空调器1的换热效率。
如图1和图2所示，进风口311设在前板111上，进风段313从出风段314倾斜地向前向上延伸，换言之，进风段313从其与出风段314的连接处倾斜地向前向上延伸。
需要说明的是，在其他可选的实施例中，进风段313还可以从其与出风段314的连接处水平地向前延伸，或者，进风段313还可以从其与出风段314的连接处向前向下延伸。优选在一些实施例中所示，进风段313从其与出风段314的连接处倾斜地向前向上延伸，以使得壁挂式空调器1的结构更加合理。
如图1和图2所示，在一些实施例中，前板111为向前凸出的弧形板，前板111包括上板部1111和下板部1112。上板部1111为前板111的上部分，下板部1112为前板111的下部分，上板部1111位于下板部1112的上方。出风口312设在上板部1111上，
出风段314的邻近出风口312的部分从出风段314的其余部分向下向前延伸，换言之，出风314包括邻近出风口312的部分和除了该部分的其余部分，出风段314的邻近出风口312的部分从其与该其余部分的连接处向下向前延伸。出风口312设在机壳10的下部。
进一步地，进风段313的风道壁包括第一进风板3131和第二进风板3132，第一进风板3131和第二进风板3132限定出进风通道3136。出风段314的风道壁包括第一出风板3141和第二出风板3142，第一出风板3141和第二出风板3142限定出出风通道3143。例如，第一出风板3141为蜗舌结构，第二出风板3142为蜗轮结构。
在图1和图2所示的实施例中，第一进风板3131和第一出风板3141相连形成一体的第一壁，第二进风板3132和第二出风板3142相连形成一体的第二壁。在其他实施例 中，第一进风板3131和第一出风板3141可以不相连，第二进风板3132和第二出风板3142可以不相连。
如图1和图2所示，在一些实施例中，电控部件90与第一进风板3131相连，即电控部件83安装在了第一进风板3131的外侧面(远离进风通道3136的侧面)上。可以理解的是，在其他可选的实施例中，电控部件90还可以安装在第一壁的其他位置的外侧面上，例如电控部件90可以安装在第一出风板3141上，或者电控部件90可以与第一进风板3131和第一出风板3141中的每一者相连，电控部件90位于进风段313的上方即可，本申请不作限制。
如图1和图2所示，换热器20配合在进风段313的进风口处，且换热器20的上端与第一进风板3131配合并与第一进风板3131之间设有第一密封结构(图中未示出)，换热器20的下端与第二进风板3132配合并与第二进风板3132之间设有第二密封结构(图中未示出)。第一密封结构和第二密封结构用于密封，避免未经换热器20换热的空气从换热器20与第一进风板3131或换热器20与第二进风板3132之间的缝隙处进入进风通道3136中，影响空调器的制冷效果。可选地，第一密封结构和第二密封结构为密封泡沫。
由于换热器20在换热过程中会产生冷凝水，为了避免冷凝水流入出风通道并从出风口312处流出。如图1和图2所示，第二进风板3132包括凹陷部3133，凹陷部3133形成用于接纳换热器20的冷凝水的接水槽3134。接水槽3134位于凹陷部3133的靠近进风通道3136的一侧。例如，凹陷部3133为第二进风板3132的一部分向远离进风通道3136的方向凹陷形成。由于凹陷部3133形成了接水槽3134，凹陷部3133也可以称作接水盘。
在图1和图2所示的实施例中，接水槽3134的开口朝上，且接水槽3134在上下方向上具有一定的深度，接水槽3134位于换热器20的下端的后方，即位于第二密封结构的后方，并且接水槽3134还位于换热器20的下方，以便有效地接纳换热器20的冷凝水。
进一步地，第一进风板3131的一部分向外凹陷以形成避让槽3135，避让槽3135位于换热器20的上端的后方，即位于第一密封结构的后方，避让槽3135用于避让换热器20形成的冷凝水，避免冷凝水沿着第一进风板3131流入出风段314内。可选地，第一进风板3131的邻近出风段314的一部分向外凹陷以形成避让槽3135。例如，避让槽3135为第二进风板3132的一部分向远离进风通道3136的方向凹陷形成，避让槽3135也可以看做为第二进风板3132的一部分向外突出形成。
在一些实施例中，第一进风板3131和/或第一出风板3141的背面设有开口朝上的水槽60，其中水槽60倾斜地设置且与接水槽3134连通。水槽60用于承接第一进风板3131和/或第一出风板3141的背面上形成的冷凝水。水槽60中的水将汇聚到接水槽3134中，随后一同排出。水槽60倾斜设置是指水槽60在其长度方向上倾斜设置。
在图1和图2所示的实施例中，第一进风板3131和第一出风板3141相连形成一体 的第一壁，第二进风板3132和第二出风板3142相连形成一体的第二壁，水槽60设置在第一壁的背面。进一步地，水槽60设置在第一壁的背面的最靠后的位置，以更好地承接冷凝水。
作为示例，水槽60沿壁挂式空调器1的长度方向延伸且倾斜设置，接水槽3134同样沿壁挂式空调器1的长度方向延伸且倾斜设置，接水槽3134的倾斜方向与水槽60的倾斜方向相同。壁挂式空调器1的长度方向可以与风道30的长度方向一致。风道30的长度方向如图3中的箭头C所示。水槽60的下端与接水槽3134的下端相连以便水槽60中的水将汇聚到接水槽3134中，接水槽3134的下端与壁挂式空调器1内设置的排水口连通，以便水槽60和接水槽3134中的水从该排水口处排出。
进一步地，在一些实施例中的壁挂式空调器1还包括保温层50，保温层50位于电控部件90与风道30之间。在图1所示的实施例中，保温层50位于第一壁和电控部件90之间，即保温层50位于电控部件90与第一进风板3131以及电控部件90与第一出风板3141之间。保温层50的设置可以实现防凝露效果，从而避免出现危急电控安全的事故发生。在其他实施例中，电控部件90与第一进风板3131和/或所述第一出风板3141之间设有保温层。
在一些实施例中，机壳10包括顶板70，顶板70沿水平方向延伸，风道30位于顶板70的下方。电控部件90位于顶板70的上方。
在其他实施例中，电控部件90的上表面可以与顶板70平齐。或者，顶板70与风道30之间具有间隔，电控部件90安装于该间隔中。
在一些实施例中，机壳10内具有安装空间，电控部件90设在该安装空间内。可选地，所述安装空间位于所述机壳10内的后上方。
如图1所示，在一些实施例中，电控部件90包括防护外壳91和电器元件92。防护外壳91包括盒体911和盒盖912。盒体911和盒盖912相连以限定出密封的防火腔。电器元件92位于该防火腔内。如上设置提高了电控部件90的防护能力，避免电器元件92故障起火，提高了壁挂式空调器1的安全系数。并且，电控部件90可以实现独立拆卸，极大的增加了测试、维修便利性。
电器元件92包括主板921和元器件922，主板921与盒体911的底板913平行且与底板913之间具有间隔，元器件922安装在主板921的远离底板913的面上。可选地，主板921与底板913之间的间隔尺寸为4mm-15mm。
如图1和图2所示，第一出风板3141包括邻近出风口312的第一平板部3144，第二出风板3142包括邻近出风口312的第二平板部3145。第一平板部3144和第二平板部3145的投影的内侧面均为直线。
如图1和图2所示，在正交于风道30的长度方向的竖直面内，第二平板部3145与出风段314的中心线之间的第一夹角θ1大于0度且小于或等于30度。
可以在确保出风通道3143内的空气的流量(出风通道3143的出风量)的情况下，减小出风通道3143占用的空间，可以使安装空间50具有足够大的安装空间，以便将原 本安装在风道30的长度方向上的侧部(例如左侧部和/或右侧部)的部件(电控部件90)安装在安装空间50内。可以有效地减小壁挂式空调器1的长度、进一步降低壁挂式空调器1的安装难度和安装所需空间。左右方向如图3中的箭头E所示。
