具体而言，如图3所示，风道件101具有风道1011，风道1011具有第一进风口和第一出风口1012，风轮102位于风道1011内，电机103可以驱动风轮102转动，风轮102转动可以驱动气流由进气口进入到风道1011内，并从出气口1012排出。
电机103包括分体设置的电机本体1031和PCB板1032，也就是说，电机本体1031和PCB板1032是分体设置的，其中，电机本体1031位于风道1011内，PCB板1032位于风道件101的外侧，第一导线105的一端与PCB板1032电连接，第一导线105的 另一端穿过风道件101上的第一过线孔1013后与位于风道件101内的电机本体1031的线圈电连接。可以理解的是，当风道模块10使用在空调器上时，PCB板1032还与空调器的电控模块电连接。
一般地，电机103的PCB板1032集成在电机103的壳体内。当电机103使用在空调器中用于驱动风轮102转动时，由于电机103和风轮102一般位于空调器的气流通道内，PCB板1032上的器件与风轮102驱动的气流接触，当气流通道内的空气湿度较大或温度较高时，容易引起PCB板1032出现故障。
有鉴于此，根据本申请实施例的空调器的风道模块10，通过使得电机103包括分体设置的电机本体1031和PCB板1032，并且PCB板1032位于风道件101的外侧，从而可以避免PCB板1032与风轮102驱动进入到风道1011内的气流接触，避免了因PCB板1032接触潮湿或高温的空气而导致的损坏，有利于提高PCB板1032的使用寿命和可靠性。
在本申请的一些实施例中，如图1-图3所示，空调器的风道模块10包括防护盒104，防护盒104位于风道件101的外侧，PCB板1032位于防护盒104内，防护盒104具有第二过线孔1041，第一导线105的一端与PCB板1032电连接，第一导线105的另一端依次穿过防护盒104上的第二过线孔1041和风道件101上的第一过线孔1013后与位于风道件101内的电机本体1031的线圈电连接。由此，通过设置防护盒104，从而一方面可以利用防护盒104的防护作用对PCB板1032进行防护，继而进一步地提高PCB板1032的使用寿命，另一方面还可以利用防护盒104的防护作用防止人手等接触到PCB板1032，避免安全隐患的发生。
在一些实施例中，防护盒104为防火材料件(例如，金属件)。由此，通过使得防护盒104为防护材料件，从而可以提高防护盒104的防火性能，进而提高防护盒104对PCB板1032防护的可靠性，而且成本比内置在电机103中的PCB板1032的方案来说要低。
在本申请的一些实施例中，防护盒104安装在风道件101的外表面上。当然，防护盒104与风道件101也可以分体设置。
在一些实施例中，防护盒104与风道件101可拆卸地相连。也就是说，防护盒104可拆卸地设在风道件101的外表面上，从而便于防护盒104的拆卸和安装，当防护盒104和风道件101其中一个损坏时，只需更换损坏的部件即可，有利于降低维修成本。
在本申请的一些实施例中，如图1和图4所示，防护盒104包括：盒体1044和盖体1045，盒体1044的背离风道件101的一侧敞开，PCB板1032安装在盒体1044内，盖体1045可枢转地设在盒体1044的敞开侧以打开或关闭盒体1044。从而便于对PCB 板1032的维修和更换。
在一些实施例中，盖体1045可拆卸地盖设在盒体1044上。由此，通过使得盒体1044与盖体1045的可拆卸设置，从而便于对PCB板1032的维修和更换。
当然，本申请不限于此，在另一些实施例中，防护盒104的面对风道件101的表面敞开，风道件101封盖防护盒104的敞开侧，由此，可以简化防护盒104的结构，降低防护盒104的制造成本。
在本申请的一些实施方式中，防护盒104与风道件101通过紧固件相连。具体而言，如图1所示，防护盒104(例如，上述的盒体1044)上设有第一紧固孔1042，风道件101的外表面上设有第一螺钉柱1014，紧固件为第一螺钉，第一螺钉穿设于第一紧固孔1042和第一螺钉柱1014，从而实现防护盒104与风道件101的可拆卸连接。
根据本申请的一些示例，盒体1044的周壁上设有凸耳10441，凸耳10441上设有在凸耳10441的厚度方向上贯穿凸耳10441的第一紧固孔1042。由此，结构简单，便于加工制造。
在一些实施例中，凸耳10441与盒体1044为一体成型件。由此，一体件的结构不仅可以保证凸耳10441与盒体1044的结构、性能稳定性，并且方便成型、制造简单，而且省去了多余的装配件以及连接工序，大大提高了凸耳10441与盒体1044的装配效率，保证凸耳10441与盒体1044连接的可靠性，再者，一体形成的结构的整体强度和稳定性较高，组装更方便，寿命更长。
根据本申请的一些示例，盒体1044的周壁上设有多个凸耳10441，每个凸耳10441上设有在凸耳10441的厚度方向上贯穿凸耳10441的第一紧固孔1042。由此，结构简单，便于加工制造。
在本申请的一些实施例中，防护盒104上设有第一卡扣部，风道件101上设有第二卡扣部，第一卡扣部与第二卡扣部卡合。具体而言，例如，第一卡扣部为卡孔，第二卡扣部为卡钩，通过卡钩与卡孔的卡合，从而实现防护盒104与风道件101的可拆卸相连，由此，结构简单，便于加工制造。
在本申请的一些实施例中，PCB板1032可拆卸地设在防护盒104内。由此，可以便于对PCB板1032的维修和更换。
在一些实施例中，PCB板1032与防护盒104通过紧固件相连。具体而言，PCB板1032上设有第二紧固孔，防护盒104内设有第二螺钉柱，紧固件即第二螺钉穿设于第二紧固孔和第二螺钉柱，从而实现PCB板1032与防护盒104的可拆卸连接。
在本申请的一些实施例中，如图4所示，PCB板1032上设有第一卡接部10321，防护盒104(例如，盒体1044，)的内壁上设有第二卡接部1043，第一卡接部10321 和第二卡接部1043卡接。由此，通过使得第一卡接部10321与第二卡接部1043卡接，从而便于实现PCB板1032与防护盒104的可拆卸连接。
在一些示例中，第二卡接部1043为凸出于防护盒104的内周壁的凸筋，PCB板1032的外周边缘被构造成为第一卡接部10321，第一卡接部10321卡设在凸筋与防护盒104的底壁之间。
在一些实施例中，防护盒104的底壁的外周边缘处设有凸起部10442，第一卡接部10321卡设在凸起部10442与凸筋之间。由此，一方面实现了PCB板1032的安装，另一方面还可以将PCB板1032与防护盒104的底壁间隔开，从而提高PCB板1032的散热效果。
在一些实施例中，防护盒104上设有多个散热孔。由此，有利于提高PCB板1032的散热效果。
在一些实施例中，风轮102为离心风轮，风道件101为蜗壳。
根据本申请实施例的空调器，包括：壳体、电控模块和上述的风道模块10。
具体而言，风道模块10位于壳体内，电控模块位于壳体内，壳体具有第二进风口和第二出风口，第二进风口与上述的第一进风口对应，第二出风口与上述的第一出风口1012对应，电控模块具有电控板，PCB板1032通过第二导线20与电控板电连接。
根据本申请实施例的空调器，通过设置上述的风道模块10，通过使得电机103包括分体设置的电机本体1031和PCB板1032，并且PCB板1032位于风道件101的外侧，从而可以避免PCB板1032与风轮102驱动进入到风道1011内的气流接触，避免了因PCB板1032接触潮湿或高温的空气而导致的损坏，有利于提高PCB板1032的使用寿命和可靠性。
在本申请的一些实施例中，壳体具有新风风道，风道模块10为位于新风风道内的新风模块，第二进风口和第二出风口均位于新风风道，第二进风口适于与室外连通。由此，可以避免PCB板1032与风轮102驱动进入到风道1011内的室外气流接触，避免了因PCB板1032接触潮湿或高温的空气而导致的损坏，有利于提高PCB板1032的使用寿命和可靠性。
