本申请提出一种风机100。
参照图1至4，在本申请实施例中，该风机100包括贯流风轮10、电机20以及底座40，贯流风轮10包括第一端板11；电机20包括内定子组件21和设于所述内定子组件21外圈的外转子组件22，所述外转子组件22与所述第一端板11为一体结构，所述外转子组件22与所述内定子组件21转动连接；底座40与所述内定子组件21固定连接。
现有技术中的电机20固定在支架上，通过电机20的外转子组件22首先带动转轴221旋转，进而通过转轴221带动风轮随之转动，其中，电机20与风轮之间留有安装间隙，导致风机100整体所占空间较大，同时零部件较大，装配繁杂，容易影响风机100的装配效率和使用效果。
在本方案中，相较于轴流风轮、离心风轮，贯流风轮10具有结构紧凑、风量大、送风平稳以及噪声低等特点，因而采用贯流风轮10能够增大气流流速、缩小占地空间而满足使用需求，其中，贯流风轮10包括第一端板11，通过将第一端板11和外转子组件22一体化设置，能够进一步简化电机20和贯流风轮10之间的装配结构，进而使电机20和贯流风轮10结构更为紧凑、连接更为牢固，从而缩小风机100所占空间，有利于预留更多空间用于走管、走线等，提升空间利用率；同时，还能够提升电机20和贯流风轮10的连接稳定性，有利于有效提升能效，降低噪音。
第一端板11和外转子组件22为一体结构，可以通过注塑一体成型、焊接、嵌接等方式使得第一端板11和外转子组件22结构紧凑，连接牢固，从而提升风机100整体结构的稳定性和运行的可靠性。
电机20还包括内定子组件21，外转子组件22设于内定子组件21外圈，换言之，接通电源后，可以使外转子组件22绕内转子组件进行旋转运动，由于外转子组件22与第一端板11为一体结构，进而能够直接带动贯流风轮10一同旋转，而平稳送风，增强传动性能，降低能耗，提升电机20的驱动可靠性和驱动高效性。
底座40与内定子组件21固定连接，如此设置，可以通过底座40装配至室外机，既能够保证内定子组件21和底座40相互固定成一整体，通过驱使外转子组件22旋转而带动贯流风轮10转动，还能够将风机100固定在室外机内，实现风机100的散热作用。此外，底座40和内定子组件21的结合体能够更为稳定地支撑外转子组件22和贯流风轮10，提升贯流风轮10旋转的可靠性，同时，还可通过分离内定子组件21和外转子组件22，使得外转子组件22和贯流风轮10的结合体、内定子组件21和底座40的结合体相互分离，方便拆装和维护。
本申请技术方案通过采用贯流风轮10的第一端板11和外转子组件22为一体结构，能够简化电机20和贯流风轮10之间的装配结构，使得电机20和贯流风轮10间结构更为紧凑、连接更为牢固，从而缩小风机100所占空间，有利于预留更多空间用于走管、走线等，提升空间利用率；同时，还能够提升电机20和贯流风轮10的连接稳定性，有利于提升电机20的驱动可靠性和驱动高效性，降低噪音。此外，电机20的内定子组件21与底座40固定连接，方便风机100整体的装配，以及更为稳定地支撑外转子组件22和贯流风轮10，从而提升贯流风轮10旋转的可靠性。同时，还可通过分离内定子组件21和外转子组件22，使得外转子组件22和贯流风轮10的结合体、内定子组件21和底座40的结合体相互分离，方便拆装和维护。
参照图2，在一实施例中，外转子组件22包括转轴221和永磁体222，转轴221固设于第一端板11中心，且与内定子组件21可转动连接，永磁体222沿内定子组件21的外圈环形设置，并与第一端板11固定连接，如此设置，可以使转轴221、永磁体222与第一端板11为一体结构，而永磁体222沿内定子组件21的外圈环形设置，便于接通电源后，在内定子组件21和永磁体222的相互作用下，通过转轴221和永磁体222与第一端板11的固定连接，能够可靠驱动贯流风轮10旋转。
转轴221、永磁体222与第一端板11的固定，可以将转轴221和永磁体222作为嵌件，通过嵌件注塑一体成型，或者，通过焊接、粘接、旋接等方式固定成一整体，有利于提升转轴221、永磁体222和第一端板11的连接牢固性，进而使贯流风轮10在电机20的作用下可靠旋转，从而提升贯流风轮10的旋转可靠性和电机20的驱动高效性。
在一实施例中，第一端板11设有嵌槽，外转子组件22还包括转子端盖，转轴221固设于转子端盖中心，永磁体222绕转轴221环形设置，并与转子端盖的周缘固定连接，转子端盖嵌设于嵌槽，如此可以增强外转子组件22和第一端板11的连接牢固性。
具体地，通过转子端盖嵌设于嵌槽，有利于增大第一端板11和转子端盖的有效接触面积，既能使贯流风轮10与外转子组件22结构更为紧凑，从而缩小风机100所占空间，还能够进一步提升贯流风轮10与外转子组件22的连接牢固性，从而提升贯流风轮10的转动可靠性和电机20的驱动高效性。其中，第一端板11、外转子组件22的固定，可以将设有转轴221、永磁体222的转子端盖作为嵌件，通过嵌件注塑一体化成型，如此可以通过转子端盖的设置，增强永磁体222、转轴221与第一端板11的连接稳定性，且方便快速生产；或者，通过焊接、粘接、旋接等方式固定成一整体。
在一实施例中，风机100还包括外围件30，外围件30环设于内定子组件21的外圈，并与第一端板11固定连接，永磁体222设于外围件30和内定子组件21之间，如此可以隔离开永磁体222和其他结构，在出模后的搬运、安装等情况下，能够有效防止永磁体222受到碰撞导致产生裂纹，甚至断裂等风险，有利于延长永磁体222的寿命。其中，外围件30可随第一端板11一同注塑成型，也可以随转子端盖一同注塑成型，有利于简化相关模具的成型工艺，同时便于提升模具的通用性。
具体地，贯流风轮10、转子端盖和外围件30均可采用例如玻璃纤维增强AS、玻璃纤维增强ABS、玻璃纤维增强PP等材料注塑成型，方便快速生产、组装。
在一实施例中，外围件30与永磁体222间隔设置，此时外围件30用来隔离开永磁体222和其他结构，在出模后的搬运、安装等情况下，能够有效防止永磁体222受到碰撞导致产生裂纹，甚至断裂等风险，有利于延长永磁体222的寿命。此外，通过设置较大直径的外围件30，即其注塑模具的通用性强，只需更换不同尺寸的永磁体222，便可形成相应的风机100。
在一实施例中，外围件30与永磁体222紧密贴合，此时永磁体222与外围件30固定连接，且与第一端板11固定连接，如此可以增大永磁体222的有效固定面积，进而提升永磁体222的连接牢固性，从而方便大扭矩的传递，适用于大尺寸贯流风轮10的传动。
在一实施例中，外围件30包括相连接的第一段311和第二段312，第一段311与第一端板11固定连接，且与永磁体222紧密贴合，第二段312位于第一段311的上方，且与永磁体222间隔设置，可以理解的，外围件30的设置，能够保护永磁体222而延长永磁体222的使用寿命，而第一段311和第二段312平行且错位设置，即第一段311和第二段312折弯连接，或者平行，且在转轴221的径向上厚度不同，如图2所示，通过第一段311与永磁体222靠近第一端板11的下部固定连接，能够在一定程度上增大永磁体222与第一端板11的连接牢固性，通过第二段312与永磁体222远离第一端板11的上部间隔设置，当永磁体222出现受损时，留有活动空间使得工作人员能够握持并拆卸永磁体222，同理，当永磁体222通过焊接、粘接等方式进行固定时，留有活动空间使得工作人员能够握持并固定永磁体222，如此能够提升永磁体222的拆装便利性。
在一实施例中，外围件30包括第一折段、第二折段和折弯连接于第一折段和第二折段之间的过渡段，第一折段与第一端板11固定连接，永磁体222固设于第一折段和过渡段的连接处，第二折段设于永磁体222远离转轴221的一侧，如此既可以保护永磁体222，还能够进一步固定永磁体222于第一端板11。同时，能够增强外围件30与第一端板11的连接牢固性。
具体地，第一折段和过渡段的连接处具有较大的结构强度和刚度，方便且可靠固定永磁体222，实现永磁体222的固定装配。
在一实施例中，外围件30设有安装槽，永磁体222包括插接部，插接部插设于安装槽，可以理解的，安装槽开设于第一折段和过渡段的连接处，永磁体222通过插接部插设于安装槽后，其余部分结构可通过过渡段进行支撑，从而增强永磁体222与外围件30的连接牢固性和连接稳定性，有效增强大扭矩传递，适用于大尺寸贯流风轮10的传动。其中，插接部可设置有多个，各插接部沿永磁体222的结构间隔排布，安装槽对应插接部设置，能够进一步增强永磁体222与外围件30的连接牢固性。当然本申请不限于此，于其他实施例中，支撑段设有安装凸部，永磁体222设有插接孔，通过安装凸部与插接孔的配合，同样能够提升永磁体222与外围件30的连接牢固性。
同理，当外围件30包括第一段311和第二段312时，由于第一段311和第二段312在径向上厚度不同，即第一段311较第二段312厚，因而安装槽可设于第一段311面向第二段312的端面，同样能够与永磁体222的插接部相互固定，进而达到增强永磁体222与外围件30的连接牢固性和连接稳定性的目的。或者，安装槽可设于第一段311面向永磁体222的端面，同样能够与永磁体222的插接部相互固定，进而达到增强永磁体222与外围件30的连接牢固性和连接稳定性的目的。
在一实施例中，第二折段与永磁体222间隔设置，如此设置，能够保护永磁体222，且方便永磁体222的拆装。当然本申请不限于此，于其他实施例中，第二折段与永磁体222固定连接。
在一实施例中，内定子组件21包括定子座211和设于定子座211内的轴承，转轴221与轴承转动连接，通过轴承的设置，能够可靠支撑贯流风轮10，使贯流风轮10能够通过转轴221相对于轴承进行旋转，降低传动过程中的摩擦系数，从而降低能耗。
在一实施例中，定子座211的外周面凸设有连接卡块212，底座40面向定子座211的端面设有与连接卡块212相适配的连接卡槽42，如此可以使定子座211和底座40相互卡接，进而实现内定子组件21和底座40的固定连接。当然本申请不限于此，于其他实施例中，定子座211和底座40间可以通过螺纹连接、旋扣等连接方式固定成一整体。
在一实施例中，转轴221、永磁体222和第一端板11注塑一体成型，即以转轴221和永磁体222作为嵌件，通过嵌件注塑一体成型形成第一端板11和转轴221、永磁体222的一体化结构，结构简单，成型快速，方便快速生产、组装，其中，可采用例如玻璃纤维增强AS、玻璃纤维增强ABS、玻璃纤维增强PP等材料进行加工。
在一实施例中，转子端盖、转轴221和永磁体222一次注塑成型出外转子组件22，外转子组件22再与第一端板11二次注塑成型，即先以转轴221和永磁体222作为嵌件，通过嵌件注塑一体成型形成外转子组件22，再将外转子组件22作为嵌件，通过嵌件注塑一体成型形成第一端板11和转轴221、永磁体222的一体化结构，其中，可采用例如玻璃纤维增强AS、玻璃纤维增强ABS、玻璃纤维增强PP等材料进行加工，方便快速生产、组装。
在一实施例中，底座40设有至少一个连接部41，连接部41沿底座40周向排布设置，如此可以通过连接部41，将底座40通过栓接、卡接、嵌接等方式装配至指定位置。由于可设置多个连接部41，且各连接部41沿底座40周向排布设置，便于提升底座40的装配稳定性，进而提升风机100的装配可靠性和装配稳定性，同时还能够通过多个连接部41使得底座40受力均匀。
在一实施例中，风机100还包括蜗壳组件50，连接部41与蜗壳组件50固定连接，可以理解的，贯流风轮10还包括与第一端板11相对设置的第二端板12，第二端板12通过轴套转动安装于蜗壳组件50内，第一端板11与外转子组件22为一体结构，此时贯流风轮10与外转子组件22一同安装在蜗壳组件50内，且通过轴套与蜗壳组件50转动连接，而装配有内定子组件21的底座40则通过连接部41与蜗壳组件50的外壁面固定连接，内定子组件21穿过蜗壳组件50，并通过轴承与外转子组件22的转轴221相连接，以完成电机20和贯流风轮10的装配。
贯流风轮10呈卧式安装于蜗壳组件50内，进一步降低蜗壳组件50的整体高度，从而使风机100的整体高度降低，而贯流风轮10与外转子组件22为一体结构，进一步降低蜗壳组件50的整体宽度，从而使风机100的整体宽度降低，如此能够实现装配有上述风机100的室外机小型化，有利于适用多种安装场景，方便用户安装。
具体地，蜗壳组件50的外壁面设有对应连接部41的安装部，连接部41和安装部可以通过栓接、插接等连接方式相互固定，进而实现底座40与蜗壳组件50的装配。当然本申请不限于此，于其他实施例中，底座40还可以直接与室外机机壳固定连接。
本申请还提出一种室外机，该室外机包括风机100，该风机100的具体结构参照上述实施例，由于本室外机采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
通过采用上述风机100，即室外机的机壳内固定有所述风机100，有利于进一步缩小室外机整体所占空间，同时通过风机100的设置，对机壳内的室外侧换热器60作用，还能够提高室外机的换热效率，降低室外机的工作噪音。
本申请还提出一种空调器，该空调器包括室外机，该室外机的具体结构参照上述实施例，由于本空调器采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
空调器包括室内机和室外机，室内机中设置有压缩机和室内侧换热器，压缩机连通室外机内的室外侧换热器60。具体地，因室外机一般需要悬挂于墙体或者窗边，若室外机重量较大，不方便用户安装和移动，故将压缩机挪至室内机中，从而大大减少了室外机的占地空间和整体重量，并降低室外机安装难度，相对室外机的安装，室内机可以直接放置在室内，并可于室内机的底部安装万向轮，从而从未方便室内机的安装，进而使得空调器的安装难度降低。使得用户个人也可实现空调的安装，无需专业的安装人士上门安装，从而节约安装成本。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
