在上述风管机室内机的优选技术方案中，室内机还包括与安装板连接的支撑梁，换热器与支撑梁可拆卸地连接。
在上述风管机室内机的优选技术方案中，支撑梁倾斜设置，换热器包括相连的换热器主体和安装部，换热器主体设置在支撑梁的斜面上，安装部位于支撑梁和外壳之间，安装部通过螺钉与支撑梁连接。
在上述风管机室内机的优选技术方案中，换热器还包括与换热器主体连接的第一卡接部，安装板上设置有第二卡接部，第一卡接部与第二卡接部能够卡接配合。
在另一方面，本发明还提供了一种风管机，该风管机包括如前所述的任一种室内机。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过将外壳设置为包括顶盖、底盘、安装板、上围板和下围板，且安装板、上围板和下围板能够共同封闭外壳的整个侧面，顶盖、底盘、上围板和下围板均与安装板可拆卸式连接，冷媒进管和冷媒出管均被夹持在上围板和下围板之间，使得在需要维修或更换换热器时，既能够将顶盖、上围板取下，从上方取出换热器总成——换热器、冷媒进管和冷媒出管，也能够将底盘、下围板取下，从下方取出换热器总成，当建筑物的房顶内部空间较小时，可选择从下方取出换热器总成，当建筑物的 房顶内部空间较大时，可选择在维修时维修人员进入房顶内从上方取出换热器总成，因此，相比于现有的风管机室内机，本发明所提供的室内机能够实现在维修时不破坏天花板，更适合使用在房顶内部空间较大的建筑中，也就是说，本发明所提供的室内机不仅适合使用在房顶内部空间较小的建筑物中，更适合使用在房顶内部空间较大的建筑物中。
进一步地，上围板朝向下围板的一侧形成有第一凹槽和第二凹槽，下围板朝向上围板的一侧形成有第三凹槽和第四凹槽，第一凹槽与第三凹槽设置位置对应，第一凹槽和第三凹槽共同形成能够允许冷媒进管穿过的第一开口，第二凹槽与第四凹槽设置位置对应，第二凹槽和第四凹槽共同形成能够允许冷媒出管穿过的第二开口，通过这样的设置，使得冷媒进管和冷媒出管能够分别被第一开口和第二开口限位，减小冷媒进管和冷媒出管发生窜动的程度。
进一步地，第一凹槽、第二凹槽、第三凹槽和第四凹槽均为半圆形凹槽，通过这样的设置，使得第一凹槽、第二凹槽、第三凹槽和第四凹槽便于加工，提高生产效率。
进一步地，第一开口的高度和第二开口的高度不同，通过这样的设置，使得冷媒进管和冷媒出管设置在不同高度，避免了冷媒进管和冷媒出管设置在同一高度，从而一定程度上避免在安装冷媒进管和冷媒出管时两者相互妨碍。
进一步地，上围板和下围板均通过螺钉与安装板连接，通过这样的设置，能够便于上围板和下围板的拆装，即使得上围板和下围板能够方便地从安装板上拆下或安装于安装板上。
进一步地，连接上围板与安装板的螺钉数量为多个且设置在上围板的左右两侧，连接下围板与安装板的螺钉数量为多个且设置在下围板的左右两侧，通过这样的设置，使得上围板和下围板能够更为牢固地与安装板连接，并且使得上围板和下围板受力更为均匀。
在另一方面，本发明还提供了一种风管机，该风管机包括如前所述的任一种室内机，这样的设置使得在需要维修或更换换热器时，既能够将顶盖、上围板取下，从上方取出换热器总成——换热器、冷媒进管和冷媒出管，也能够将底盘、下围板取下，从下方取出换热器总成，当建筑物的房顶内部空间较小时，可选择从下方取出换热器总成，当建 筑物的房顶内部空间较大时，可选择在维修时维修人员进入房顶内从上方取出换热器总成，因此，相比于现有的风管机，本发明所提供的风管机的室内机能够实现在维修时不破坏天花板，更适合使用在房顶内部空间较大的建筑中，也就是说，本发明所提供的风管机的室内机不仅适合使用在房顶内部空间较小的建筑物中，更适合使用在房顶内部空间较大的建筑物中。

基于背景技术指出的现有风管机室内机的换热器仅能从室内机的下方拆卸、取出，该种形式的室内机并不十分适合所有类型建筑的问题，本发明提供了一种风管机室内机，旨在使得风管机室内机不仅适合使用在房顶内部空间较小的建筑物中，更适合使用在房顶内部空间较大的建筑物中。
具体地，如图1和2所示，该风管机室内机包括外壳和可拆卸地连接于外壳中的换热器1，换热器1上分别连接有冷媒进管2和冷媒出管3，外壳包括顶盖41、底盘(底盘图中未示出)、安装板42、上围板43和下围板44，安装板42、上围板43和下围板44能够共同封闭外壳的整个侧面，顶盖41、底盘、上围板43和下围板44均与安装板42可拆卸式连接，冷媒进管2和冷媒出管3均被夹持在上围板43和下围板44之间。其中，安装板42、上围板43和下围板44能够共同封闭外壳的整个侧面，也就是说，安装板42、上围板43和下围板44共同封闭了外壳的除去顶盖41和底盘之外的四个侧面。此外，顶盖41、底盘、上围板43和下围板44均与安装板42可拆卸式连接，可以是顶盖41、底盘、上围板43和下围板44分别与安装板42通过螺钉5或螺栓连接，也可以是顶盖41、底盘、上围板43和下围板44分别与安装板42通过卡接的方式连接，还可以是顶盖41、底盘、上围板43和下围板44中的一些分别与安装板42通过螺钉或螺栓连接，顶盖41、底盘、上围板43和下围板44的另一些分别与安装板42通过卡接的方式连接，本领域技术人员可以在实际应用中灵活地设置顶盖41、底盘、上围板43和下围板44与安装板42的连接方式，这种对于顶盖41、底盘、上围板43和下围板44与安装板42连接方式的调整和改变不构成对本发明的限制，均应限定在本发明的保护范围之内。
在更换或维修换热器1时通常需要将换热器1连同冷媒进管2和冷媒出管3整体取出，也就是说需要将换热器总成取出。该风管机室内机在取出换热器总成时，可以是将顶盖41、上围板43取下，从上方取出换热器总成，也可以是将底盘、下围板44取下，从下方取出换热器总成，由于风管机室内机具备两种取出换热器总成的方式，当建筑物的房 顶内部空间较小时，可选择从下方取出换热器总成，当建筑物的房顶内部空间较大时，可选择在维修时维修人员进入房顶内从上方取出换热器总成，因此，相比于现有的风管机室内机，本发明所提供的室内机能够实现在维修时不破坏天花板，更适合使用在房顶内部空间较大的建筑中，也就是说，本发明所提供的室内机不仅适合使用在房顶内部空间较小的建筑物中，更适合使用在房顶内部空间较大的建筑物中。
优选地，如图1所示，上围板43朝向下围板44的一侧形成有第一凹槽430a和第二凹槽430b，下围板44朝向上围板43的一侧形成有第三凹槽440a和第四凹槽440b，第一凹槽430a与第三凹槽440a设置位置对应，第一凹槽430a和第三凹槽440a共同形成能够允许冷媒进管2穿过的第一开口，第二凹槽430b与第四凹槽440b设置位置对应，第二凹槽430b和第四凹槽440b共同形成能够允许冷媒出管3穿过的第二开口。上述优选实施方式的一种替代性实施方式是，上围板43不具有第一凹槽430a和第二凹槽430b，下围板44也不具有第三凹槽440a和第四凹槽440b，而是上围板43与下围板44之间具有空隙，冷媒进管2和冷媒出管3从该空隙穿过。本领域技术人员可以在实际应用中灵活地设置冷媒进管2和冷媒出管3的具体安装形式，这种对于冷媒进管2和冷媒出管3的具体安装形式的调整和改变不构成对本发明的限制，均应限定在本发明的保护范围之内。
优选地，继续参照图1，第一凹槽430a和第三凹槽440a为直径相同的半圆形凹槽，第二凹槽430b和第四凹槽440b为直径相同的半圆形凹槽，第一开口和第二开口均为圆形。也就是说，冷凝进管和冷凝出管均从圆形的开口穿过，当第一开口和第二开口的直径大小合适时，第一开口和第二开口能够较好地对冷媒进管2和冷媒出管3进行限位，防止冷媒进管2和冷媒出管3在分别在第一开口和第二开口的径向上发生窜动。上述优选实施方式的一种替代性实施方式是，第一凹槽430a、第二凹槽430b、第三凹槽440a和第四凹槽440b分别设置为矩形凹槽。本领域技术人员可以在实际应用中灵活地设置第一凹槽430a、第二凹槽430b、第三凹槽440a和第四凹槽440b的具体结构，只要第一凹槽430a和第三凹槽440a能够共同形成允许冷媒进管2穿过的第一开口，且第二凹槽430b和第四凹槽440b能够共同形成允许冷媒出管3穿过的第二开 口即可。
优选地，继续参照图1，第一开口的高度和第二开口的高度不同，如前所述，第一凹槽430a和第三凹槽440a共同形成第一开口，第二凹槽430b和第四凹槽440b共同形成第二开口。这样的设置使得冷媒进管2和冷媒出管3设置在不同高度，避免了冷媒进管2和冷媒出管3设置在同一高度，从而一定程度上避免在安装冷媒进管2和冷媒出管3时两者相互妨碍。
优选地，继续参照图1，上围板43和下围板44均通过螺钉5与安装板42连接。这样的设置能够便于上围板43和下围板44的拆装，拆装上围板43和下围板44省时省力。
优选地，继续参照图1，连接上围板43与安装板42的螺钉5数量为多个且设置在上围板43的左右两侧，连接下围板44与安装板42的螺钉5数量为多个且设置在下围板44的左右两侧。例如，如图1所示，连接上围板43与安装板42的螺钉5数量为四个，其中两个螺钉5设置在上围板43的左侧将上围板43的左侧与安装板42连接，另外两个螺钉5设置在上围板43的右侧将上围板43的右侧与安装板42连接，连接下围板44与安装板42的螺钉5数量为三个，其中两个螺钉5设置在下围板44的左侧将下围板44的左侧与安装板42连接，另外一个螺钉5设置在下围板44的右侧将下围板44的右侧与安装板42连接。通过多个螺钉5来连接，且螺钉5在上围板43和下围板44的左右两侧均有设置，这样的设置使得上围板43和下围板44能够更为牢固地与安装板42连接，并且使得上围板43和下围板44受力更为均匀。
优选地，如图1和2所示，室内机还包括与安装板42连接的支撑梁6(为了更清楚的示出室内机的结构，图1和2均在示出安装板42的同时也示出了设置在外壳内的支撑梁6)，换热器1与支撑梁6可拆卸地连接。也就是说，换热器1安装在支撑梁6上，并通过支撑梁6设置在室内机的外壳中。换热器1与支撑梁6可拆卸地连接，可以是换热器1与支撑梁6通过螺钉或螺栓连接，也可以是换热器1与支撑梁6通过卡接的方式连接，本领域技术人员可以在实际应用中灵活地设置换热器1与支撑梁6的连接方式，这种对于换热器1与支撑梁6连接方式的调整和改变不构成对本发明的限制，均应限定在本发明的保护范围之 内。当然，室内机也可以不包括支撑梁6，换热器1可以直接与外壳的安装板42连接来使得换热器1设置在外壳中。
优选地，继续参照图1，支撑梁6倾斜设置，换热器1包括相连的换热器主体11和安装部12，换热器主体11设置在支撑梁6的斜面上，安装部12位于支撑梁6和外壳之间，安装部12通过螺钉5与支撑梁6连接。需要说明的是，上述的支撑梁6的斜面可以是因支撑梁6倾斜设置而产生的斜面，也可以是支撑梁6本身所具有的斜面。换热器主体11设置在支撑梁6的斜面上，可以是换热器主体11与支撑梁6的斜面没有通过其他构件连接，而是螺钉5将安装部12与支撑梁6连接后，换热器主体11即与支撑梁6的斜面接触而实现将换热器主体11设置在支撑梁6的斜面上，还可以是换热器主体11与支撑梁6的斜面通过其他构件连接。还需要说明的是，安装部12通过螺钉与支撑梁6连接，可以是螺钉仅连接安装部12和支撑梁6，螺钉贯穿安装部12之后插入支撑梁6，还可以是螺钉5连接外壳、安装部12和支撑梁6，螺钉5依次贯穿外壳、安装部12之后插入支撑梁6(图1和2中所示的正是此种情形)。
优选地，换热器1还包括与换热器主体11连接的第一卡接部，安装板42上设置有第二卡接部，第一卡接部与第二卡接部能够卡接配合(第一卡接部和第二卡接部附图中未示出)。第一卡接部与第二卡接部卡接配合使得换热器主体11与安装板42连接，从而使得换热器主体11设置在支撑梁6的斜面上。第一卡接部可以是卡爪、卡口，相应地，第二卡接部可以是卡勾、卡扣，本领域技术人员可以在实际应用中灵活地设置第一卡接部与第二卡接部的具体结构，只要第一卡接部与第二卡接部能够卡接配合从而使得换热器主体11与安装板42连接即可。通过第一卡接部与第二卡接部的卡接配合将换热器主体11与安装板42连接，便于将换热器主体11与安装板42的连接与分离。
在另一方面，本发明还提供一种风管机，该风管机包括如前所述的任一种风管机室内机。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换 之后的技术方案都将落入本发明的保护范围之内。
