具体实施方式
下面结合实施例对本公开做进一步说明，但不局限于说明书上的内容。
相关技术中，风管机内的风道中需要设置换热器对气体进行换热，换热器会产生冷凝水，因此在换热器下方、风道的内部会设置接水盘来承接换热器上产生的冷凝水，以避免冷凝水滴落影响风管机的使用效果，现有的风管机均仅仅考虑接水盘能够对冷凝水的承接作用，在对风管机的换热效果的改良上均是针对风机或者针对换热器。然而经过申请人的研究以及通过仿真模拟实验数据进行分析后发现，风管机在换热过程中，风道内的所有部件均会对风道内的气流产生影响，单纯的考虑风机或换热器仅仅能够起到一部分增加换热效果的目的，而为了保证接水盘的承接效果，接水盘必然存在一定的高度，此高度在风道的下部起到阻挡作用，同时为了减小风管机的占用空间，会尽可能的减小风机和换热器之间的间距，造成了接水盘也距离风机很近，使得接水盘对风机的进出风均产生较大的影响，也即接水盘实际上也是一个对风道内气流产生影响的重要因素，如何避免接水盘对风机的风量影响是能够有效提升风管机换热效率的重要参数。
为此，如图1至图4所示，本公开提供了一种风管机，包括：壳体1，所述壳体1上形成有风口；风机2，所述风机2可转动地设置于所述壳体1内；接水盘3，所述接水盘3设置于所述壳体1内，且所述接水盘3位于所述风机2和所述风口之间；当所述风口11作为进风口时，所述风机2的吸风口21的朝向相对于水平方向向上倾斜。在风口11作为进风口时，风机2由风口11吸入气体，风机2向远离接水盘3的方向倾斜，吸风口21从远离接水盘3的部分吸风，避免了接水盘3对气流阻挡而影响风机2进风，保证风机2的风量，最终保证风管机的换热效果。
或者，当所述风口11作为出风口时，所述风机2的排风口22的朝向相对于水平方向向上倾斜。在风口11作为出风口时，风机2排出的气流经过风口11吹出，由于风机2的排风口22吹出的气流大部分从接水盘3的上方流过而不会被接水盘3所阻挡，保证风机2的风量，最终保证风管机的换热效果。
当所述风口11作为进风口时，所述吸风口21的朝向与水平方向向形成第一倾斜角α，所述第一倾斜角α的角度范围为0°≤α≤12°。优选的，所述第一倾斜角α的角度范围为0°＜α≤12°。
对本例的风管机进行仿真试验，改变第一倾斜角α的数值，其中，以相对于水平方向向上倾斜为正角度，以相对于水平方向向下倾斜为负角度，仿真结果如下：
角度 转速(rpm) 风量(m 3/h) 噪音(dB)
-3.0 2200 478 46.2
0.0 2200 518 43.5
7.5 2200 533 42.2
12.0 2200 525 43.7
14.0 2200 493 45.8
根据仿真数据可知，当α为7.5°时，风量达到最大值，噪音达到最小值；当α增大到12°时，风量开始减小，噪音开始增大；当α继续加大到14°时，风量衰减继续增大，噪音明显增加；当α减小到0°时，风量开始减小，噪音开始增大；当α继续减小到-3°时，风量衰减继续增大，噪音明显增加；也可以说，第一倾斜角α在0°≤α≤12°的范围内的风量及噪音偏差不大且效果最好，而超过临界值后有较大变化，无法保证风管机的正常工作。
当所述风口11作为出风口时，所述排风口22的朝向与水平方向形成第二倾斜角β，所述第二倾斜角β的角度范围为0°≤β≤15°。优选的，所述第二倾斜角β的角度范围为0°＜β≤15°。
对本例的混流风机进行仿真试验，改变第二倾斜角β的数值，其中以相对于水平方向向上倾斜为正角度，以相对于水平方向向下倾斜为负角度，仿真结果如下：
角度 转速(rpm) 风量(m 3/h) 噪音(dB)
-2.0 2200 469 48.8
0.0 2200 504 42.8
7.2 2200 526 41.3
15.0 2200 510 42.6
16.0 2200 476 44.2
根据仿真数据可知，当β为7.2°时，风量达到最大值，噪音达到最小值；当β 增大到15°时，风量开始减小，噪音开始增大；当β继续加大到16°时，风量衰减继续增大，噪音明显增加；当β减小到0°时，风量开始减小，噪音开始增大；当β继续减小到-2°时，风量衰减继续增大，噪音明显增加；也可以说，第二倾斜角β在0°≤β≤15°的范围内的风量及噪音偏差不大且效果最好，而超过临界值后有较大变化，无法保证风管机的正常工作。
所述风口包括下风口11，所述接水盘3设置于所述下风口11和所述风机2之间；或，所述风口包括侧风口12，所述接水盘3设置于所述侧风口12和所述风机2之间。
所述风口包括下风口11，所述风机2具有第一朝向和第二朝向，在所述第一朝向时，所述下风口11作为进风口，在所述第二朝向时，所述下风口11作为出风口。也即此时风管机可以根据风机2的朝向切换进行进出风方向的切换。
当所述风机2在所述第一朝向和所述第二朝向之间切换过程中，所述风机2的转动角度小于180°，且所述风机2具有排风口的朝向为竖直向上的位置。也即，风机2在转动的过程中，其排风口22的朝向是先向上转动然后在向下转动的。
当所述风机2在所述第一朝向和所述第二朝向之间切换过程中，所述风机2的转动角度大于180°，且所述风机2具有排风口的朝向为竖直向下的位置。也即，风机2在转动的过程中，其排风口22的朝向是先向下转动然后在向上转动的。
所述风口还包括侧风口12，在所述第一朝向时，所述侧风口12作为出风口，在所述第二朝向时，所述侧风口12作为进风口。
在风管机处于制冷模式时，风机2处于所述第一朝向，所述下风口11作为进风口，此时侧风口12作为出风口，实现水平出风而实现瀑布式制冷的效果；在风管机处于制热模式时，风机2处于所述第二朝向，所述下风口11作为出风口，侧风口12作为进风口，实现竖直向下制热实现快速制热的效果。
所述风管机还包括换热器4，所述换热器4设置于所述壳体1内，且所述接水盘3位于所述换热器4的下方。
所述风机2为混流风机。
显然，本公开的上述实施方式仅仅是为清楚地说明本公开所作的举例，而并非是对本公开的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无法对所有的实施方式予以穷举。凡是属于本公开的技术方案所引伸出的显而易见的变化或变动仍处于本公开的保护范围之列。
