具体实施方式
正如背景技术中所述，相关技术的方案中，空调内机在制冷时易在面板表面形成凝露，经发明人研究发现，造成这一现象的原因在于在制冷状态下冷风会吹到面板上，空调内机吹出的冷风与环境中的热风在面板处交互，从而在面板表面形成凝露。
有鉴于此，本申请旨在提供一种空调内机及空调器，通过在风道的侧壁上设置背离风道的折弯段，并将面板设置在折弯段之外，从而降低了冷风吹到面板上的几率，进而降低面板上凝露的产生几率。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例一
图1是本申请一实施例提供的空调内机在第一状态下的结构简图；图2是本申请一实施例提供的空调内机在第二状态下的结构简图；图3是本申请一实施例提供的空调内机在第三状态下的结构简图；图4是本申请一实施例提供的风道组件的结构简图。
请参照图1-图4，本实施例提供了一种空调内机，包括机壳100以及设置在机壳100内的风道组件，机壳100上设有进风口101和出风口 102；沿第一方向X，机壳100包括分别位于出风口102的两侧的第一面板110和第二面板120。
风道组件连通进风口101和出风口102，从进风口101至出风口102一侧，风道组件依次包括蒸发器210、贯流风扇220、蜗壳230、蜗舌240和导风板250，导风板250位于蜗壳230和蜗舌240朝向出风口102的一侧，且可相对于出风口102移动。导风板250与出风口102具有相对的第一状态和第二状态，在第一状态下，导风板250遮蔽出风口102；在第二状态下，导风板250朝向蜗壳230移动以显露出风口102，从而形成如图1-图3中所示结构。
在图1-图3所示结构中，风道组件还包括相对设置的第一侧壁和第二侧壁，第一侧壁和第二侧壁之间形成风道；其中，第一侧壁由蜗舌240构成，第二侧壁由蜗壳230和导风板250共同组成。
具体来说，第一侧壁包括第一主体段241和第一折弯段242，第一折弯段242连接第一主体段241靠近出风口102的一端，且第一折弯段242朝向背离风道的方向弯折。第二侧壁包括第二主体段231和第二折弯段252，第二折弯段252连接第二主体段231靠近出风口102的一端，且第二折弯段252朝向背离风道的方向弯折。沿第一方向X，第一面板110和第二面板120之间的距离大于第一折弯段242和第二折弯段252之间的距离。
通过上述设置，空调内机在制冷时，冷风吹到第一主体段241和第一折弯段242的临界位置时，大部分冷风会沿第一主体段241的切线方向直接吹出。同样的，在第二主体段231和第二折弯段252的临界位置时，大部分冷风会沿第二主体段231的切线方向直接吹出。由于第一面板110和第二面板120之间的距离大于第一折弯段242和第二折弯段252之间的距离，因此进一步降低了冷风吹到第一面板110和第二面板120上的几率，从而降低了凝露产生的几率。
此外，通过设置第一折弯段242和第二折弯段252还增大了出风口102的面积。
请继续参照图1-图3，本实施例中第一侧壁包括背离风道的第一背风面，在第一背风面上，第一主体段241与第一折弯段242之间的夹角为钝角，从而确保沿第一主体段241的切线方向吹出的冷风不会再吹到第一折弯段242上，有利于降低第一面板110上凝露的产生几率。
第二侧壁包括背离风道的第二背风面，在第二背风面上，第二主体段231与第二折弯段252之间的夹角为钝角，从而确保沿第二主体段231的切线方向吹出的冷风不会再吹到第二折弯段252上，有利于降低第二面板120上凝露的产生几率。
在一个可能的实施方式中，本实施例的第一侧壁还包括第一连接段243，第一连接段243连接第一折弯段242背离第一主体段241的一端，第一连接段243与第一面板110之间形成有间隙，间隙内靠近出风口102的一侧设有凸起结构，凸起结构用于遮挡间隙，从而防止冷风从该间隙内吹向第一面板110，降低第一面板110上产生凝露的几率。
具体的，本实施例中的凸起结构包括设置在第一面板110上的第一凸起111和设置在第一连接段243上的第二凸起244，在第二方向Y上，第一凸起111和第二凸起244至少部分重合；其中，第二方向Y平行于风道的出风方向，第一方向X与第二方向Y互相垂直。通过设置交错的两层凸起，能够更好的阻挡冷风吹向第一面板110。
优选地，本实施例中第一凸起111和第二凸起244均沿空调内机的轴向延伸，从而保证凸起结构具有良好的挡风效果。第一凸起111抵接在第一连接段243上。考虑到加工时出模的影响，第二凸起244沿第一方向X的长度优选大于等于2.5mm，第二凸起244沿第二方向Y的长度优选大于等于3.2mm。
本实施例中，第一连接段243上还设有多个卡槽2431，多个卡槽2431沿空调内机的轴向间隔设置；第一面板110上设有多个卡扣，多个卡扣与多个卡槽2431一一对应，第一面板110与第一连接段243卡接固定。
在一个可能的实施方式中，本实施例的导风板250包括导风板主体 251和导风板端面，导风板端面位于导风板主体251的一端，且朝向背离第二面板120的方向设置。在第一状态下，导风板主体251用于遮挡出风口102。
在第二状态下，导风板端面抵接在蜗壳230上，导风板端面与蜗壳230共同构成第二侧壁，其中，导风板端面形成上述第二弯折段252。
具体的，本实施例的蜗壳230朝向出风口102的一侧设有抵接部232，导风板端面抵接在抵接部232上。
本实施例的风道组件还包括设置在出风口102处的竖摆叶260，竖摆叶260可相对于出风口102转动，从而改变出风口102的出风方向，图1-图3中箭头所示为各自的实际出风方向。
具体的，在图1所示结构中，竖摆叶260大体平行于第二方向Y，此时冷风沿第二方向Y直吹，由于在风道的第一侧壁上设置了第一折弯段242，在风道的第二侧壁上设置了第二折弯段252，在第二方向Y上与第一折弯段242和第二折弯段252对应的区域是无风区域，进而不会有冷风直接吹向第一面板110和第二面板120，因此空调内机在制冷时，第一面板110和第二面板120上不会产生凝露。
在图2所示结构中，竖摆叶260沿第二方向Y向左偏移，此时冷风朝向第一侧壁一侧吹出，在第二方向Y上，与第一折弯段242对应的区域会有部分冷风，因此第二面板120上不会产生凝露。与第二折弯段252对应的区域是无风区域，由于设置了凸起结构，因此第一面板110上的第一凸起111和第一连接段243上的第二凸起244会共同阻止冷风进入第一连接段243与第一面板110之间的间隙内，从而降低了冷风吹到第一面板110上的几率，进而降低了第一面板110上凝露产生的几率。
在图3所示结构中，竖摆叶260沿第二方向Y向右偏移，此时冷风朝向第二侧壁一侧吹出，在第二方向Y上，与第一折弯段242对应的区域是无风区域，因此第一面板110上不会产生凝露。与第二折弯段252对应的区域会有部分冷风，由于第二面板120在第一方向X上位于第二折弯段252之外，冷风吹出时会沿第二折弯段252末端的切线方向出风， 从而降低了冷风吹到第二面板120上的几率，进而降低了第二面板120上凝露产生的几率。
综上，本实施例的空调内机在制冷时，冷风吹到第一主体段241和第一折弯段242的临界位置时，大部分冷风会沿第一主体段241的切线方向直接吹出。同样的，在第二主体段231和第二折弯段252的临界位置时，大部分冷风会沿第二主体段231的切线方向直接吹出。由于第一面板110和第二面板120之间的距离大于第一折弯段242和第二折弯段252之间的距离，因此进一步降低了冷风吹到第一面板110和第二面板120上的几率，从而降低了凝露产生的几率。
