热泵热水器是继电热水器、燃气热水器以及太阳能热水器之后出现的一种新型热水器。热泵热水器通过吸收空气的热量，来加热水箱中的水。以此，避免了电热水器漏电、干烧以及燃气热水器使用时可能发生煤气中毒的问题、克服了太阳能热水器受天气影响大的缺点，具有高效节能、安全环保、全天候运行、使用方便等优点。
如图1所示，热泵热水器100包括水箱组件1和热泵装置2。如图2所示，水箱组件1包括第一壳体11、水箱本体12和冷凝器。水箱本体12设置于第一壳体11内，且被配置为储存水。水箱本体12具有进水口121和出水口122。例如，进水口121和出水口122可以设置在水箱本体12的轴向的两端。进水口121被配置为连接外部管道，以使冷水可以通过进水口121流入水箱本体12内，冷水被加热后可以经由出水口122流出水箱本体12，以供用户使用。
在一些实施例中，冷凝器设置在第一壳体11内，冷凝器可以为空心的管状结构的导热件。例如，冷凝器为铜管且缠绕在水箱本体12的外部。
如图1至图4所示，热泵装置2位于水箱组件1的顶部。热泵装置2包括第二壳体21、以及容纳在第二壳体21内的压缩机22和蒸发器23。蒸发器23被配置为吸收空气中的热量。压缩机22具有进气口和排气口，压缩机22的排气口与冷凝器的一端相连，压缩机22的进气口与蒸发器23的一端相连。
在一些实施例中，热泵装置2还包括节流组件24。节流组件24连接在蒸发器23的另一端和冷凝器的另一端之间。压缩机22、冷凝器、节流组件24和蒸发器23依次相连，以构成制冷剂循环回路。制冷剂可以在该制冷剂循环回路中流动，从而可以实现冷凝器与水箱本体12换热，以对水箱本体12内的水进行加热。
在一些实施例中，热泵装置2还包括风机组件25。风机组件25设置于蒸发器23的一侧，且被配置为将外部空气导入蒸发器23。蒸发器23内部的制冷剂吸收热量之后，回到压缩机22中再次被压缩，如此反复循环工作，空气中的热能被不断送到水中，使水箱本体12内的水温升高。
在一些实施例中，热泵装置2还包括电控盒26。电控盒26与压缩机22、蒸发器23和风机组件25耦接。电控盒26和压缩机22位于蒸发器23的同一侧，且与风机组件25相对。电控盒26被配置为控制热泵热水器100的正常工作。如图4所示，风机组件25和压缩机22分别位于蒸发器23的厚度方向(如图2所示的左右方向)的两侧。
当热泵热水器100工作时，风机组件25运转。在风机组件25的作用下，大量的空气流过蒸发器23的外表面。空气中的热量被蒸发器23吸收，空气的温度降低变成冷气。之后所述冷气从风机组件25排出。
在此过程中，蒸发器23内部的制冷剂吸热汽化后被吸入压缩机22中。压缩机22将回流的低压制冷剂气体压缩成高温、高压的气体，并送入缠绕在水箱本体12外侧壁的冷凝器内。高温、高压气体产生的热量经冷凝器以热传导的方式传递至水箱本体12内部，以加热水箱本体12内的水。
而冷凝器中的制冷剂在压力的持续作用下被冷却成液体，该液体经节流组件24(如膨胀阀)节流降温后再次流入蒸发器23。由于蒸发器23内的压力骤然降低，因此液态的制冷剂在蒸发器23处迅速蒸发成气态并吸收大量的热量。如此反复循环，空气中的热能被不断送到水中，使水箱本体12里的水温升高。
在一些实施例中，如图20和图28所示，热泵装置2还包括底座28，底座28设在安 装板13的远离水箱组件1的一侧。压缩机22、蒸发器23、节流组件24、风机组件25和电控盒26分别设在底座28的远离水箱组件1的一侧(如上侧)。底座28与水箱组件1连接，以完成热泵装置2与水箱组件1的装配。
在一些实施例中，如图2至图5所示，水箱组件1包括安装板13。安装板13设在第一壳体11的轴向的一端。例如，安装板13设于第一壳体11的顶部，以便于安装热泵装置2。安装板13与第一壳体11之间限定出第一容纳腔10，水箱本体12位于第一容纳腔10内。
在一些实施例中，第二壳体21的下端与安装板13可拆卸地连接。第二壳体21与安装板13构成第二容纳腔20(即容纳腔)，压缩机22、蒸发器23、节流组件24、风机组件25和电控盒26均位于第二容纳腔20内。
如图1所示，热泵热水器100还包括显示装置27(如显示面板)，显示装置27设置于第二壳体21。显示装置27被配置为显示水箱本体12内的水温。
通常，热泵装置2的第二壳体21为整体式外壳。装配显示装置27时，是先将显示装置27安装于整体式外壳后，再将显示装置27与电控盒26进行接线操作。常见的整体式外壳缺少预固定结构，安装过程中第二壳体21容易出现脱落的情况，导致装配效率降低。并且整体式外壳限制了操作空间，使得接线困难。
在一些实施例中，第二壳体21为分体式结构，第二壳体21包括第一子壳体和第二子壳体，但是第一子壳体和第二子壳体的连接处可能存在渗水的问题。
为解决上述问题中的至少之一，本公开一些实施例提供一种热泵热水器100，第二壳体21和安装板13中的一个设置有容置部131，第二壳体21和安装板13中的另一个设有第一卡合部215，第一卡合部215卡合在容置部131内，以使第二壳体21和安装板13相连。例如，第二壳体21包括第一卡合部215，第一卡合部215可以为凸台。安装板13包括容置部131，容置部131可以为凹槽。
这样，当在第二壳体21上安装显示装置27时，可以先通过第一卡合部215和容置部131的配合将第二壳体21预安装在安装板13上，再对显示装置27进行接线，从而避免接线时第二壳体21从安装板13上脱落。并且，该装配方式简单，操作方便，可以提高装配效率。
如图12所示，容置部131设置在安装板13的外周缘。容置部131由安装板13的一部分朝向安装板13的中心轴线凹入形成。如图6和图9所示，第一卡合部215设在第二壳体21的内壁面上，且位于第二壳体21的邻近安装板13的一侧。装配时，可以通过第一卡合部215与容置部131的配合，将第二壳体21预安装至安装板13上。
在一些实施例中，第一卡合部215的一端朝第二壳体21的中心轴线方向延伸，第一卡合部215的一端的另一端与第二壳体21相连接。第一卡合部215的所述一端的宽度小于所述另一端的宽度，以便与对应的容置部131配合。
在一些实施例中，如图2和图12所示，安装板13包括彼此相连的安装板本体132和第一配合部133。安装板本体132与第一壳体11相连，第一配合部133设在安装板本体132的周向上且沿朝向靠近第二壳体21的顶部的方向延伸，第一配合部133上形成有容置部131。
如图3和图12所示，安装板本体132的形状与第一壳体11的顶部的形状相适配，以将热泵装置2与水箱本体12间隔开，避免水箱本体12内的水进入第二壳体21内而造成热泵装置2的线路短路。
第一配合部133位于安装板本体132的边缘并向远离所述水箱组件1的一侧延伸。例如，第一配合部133沿安装板本体132的周向延伸，且垂直于安装板本体132。此外，第一配合部133与安装板本体132的外周面间隔开，以使第二壳体21与安装板13装配后，第一配合部133能够位于第二壳体21内，此时第二壳体21的下端面与安装板本体132的外周面止抵。
由此，使得安装板13的结构简单、方便加工，并且能够提高第二壳体21和安装板13的连接处的密封性，避免外界液体从所述连接处进入第二壳体21内部，从而对压缩机22 等起到防水作用。
如图6至图9所示，第二壳体21包括可拆卸连接的第一子壳体211和第二子壳体212。第一卡合部215包括第一子卡合部2111和第二子卡合部2121。第一子壳体211上设置有多个第一子卡合部2111，多个第一子卡合部2111沿第一子壳体211的周向间隔排布。第二子壳体212上设置有多个第二子卡合部2121，多个第二子卡合部2121沿第二子壳体212的周向间隔排布。
多个容置部131包括多个第一子容置部1311和多个第二子容置部1312。安装时，第一子卡合部2111分别位于第一子容置部1311内，以将第一子壳体211预安装在安装板13上。第二子卡合部2121分别位于第二子容置部1312内，以将第二子壳体212预安装于安装板13。
在一些实施例中，显示装置27设置于第一子壳体211和第二子壳体212中的一个。如图6所示，显示装置27设置于第一子壳体211。此时，当在第一子壳体211上安装显示装置27时，可以先通过第一子卡合部2111与第一子容置部1311的配合，将第一子壳体211预安装在安装板13上之后，再对显示装置27进行接线，从而避免接线时第一子壳体211从安装板13上脱落。最后再将第二子壳体212与第一子壳体211连接，从而为接线操作提供足够的空间。
在一些实施例中，多个第一子卡合部2111中位于第一子壳体211的周向的两端的至少两个第一子卡合部2111具有第一导向面。多个第二子卡合部2121中位于第二子壳体212的周向的两端的至少两个第二子卡合部2121具有第二导向面。
例如，所述至少两个第一子卡合部2111包括两个第一子卡合部2111，两个第一子卡合部2111的第一导向面彼此相对设置。所述至少两个第二子卡合部2121包括两个第二子卡合部2121，两个第二子卡合部2121的第二导向面彼此相对设置。
可以理解的是，多个第一子容置部1311中的至少两个具有第三导向面，第三导向面与第一导向面接触。多个第二子容置部1312中的至少两个具有第四导向面，第四导向面与第二导向面接触。
安装时，第一导向面与第三导向面相配合，以将第一子壳体211快速安装至安装板13上。第二导向面与第四导向面相配合，以将第二子壳体212快速安装至安装板13上。这样，有利于提高壳体与安装板13之间的装配效率。
在一些实施例中，沿安装板13的径向，第二子壳体212上的多个第二子卡合部2121分别位于第二子壳体212周向上的两端。如此设置，能够保证第二子壳体212的中部具有充足的空间，便于将尺寸较大的风机组件25安装至第二容纳腔20中邻近第二子壳体212的一侧，以充分利用第二壳体21内的空间，使得热泵装置2的排布紧凑，减小热泵装置2整体的体积。
在一些实施例中，第二壳体21还包括至少一个密封件216。密封件216设置于第二壳体21的内侧壁上，且位于第二壳体21的邻近安装板13的一侧。例如，密封件216位于所述多个第一卡合部215中的相邻两个第一卡合部215之间。装配时，密封件216与第一配合部133的外周面止抵。
由此，可以进一步提高安装板13与第二壳体21之间的密封性，避免外界杂质或液体进入第二壳体21内，保证了第二壳体21内部的清洁度。
在一些实施例中，如图18所示，第一配合部133的外周面设有至少一个第一限位部136，即第一限位部136设置于第一配合部133的邻近第二壳体21的一侧。密封件216与第一限位部136止抵，第一限位部136可支撑在对应的密封件216上。
在一些实施例中，所述至少一个密封件216包括多个密封件216，所述多个密封件216沿第二壳体21的内侧壁的周向间隔排布。所述至少一个第一限位部136包括多个第一限位部136，所述多个第一限位部136沿安装板13的周向间隔排布。
这样，通过第一限位部136和密封件216的配合，可以避免第二壳体21和安装板13沿上下方向的相对移动，避免安装板13与第二壳体21脱离配合。并且，可以进一步起到防水作用。
在一些实施例中，第一子壳体211和第二子壳体212中的一个上设有第一卡扣2113，安装板13上设有第二限位部134，第一卡扣2113与第二限位部134止抵。如图6和图8所示，第一子壳体211的内壁面的邻近安装板13的一端设有两个第一卡扣2113。两个第一卡扣2113分别位于第一子壳体211的周向的两端，且两个第一卡扣2113位于第一子卡合部2111的远离密封件216的一侧。
如图12所示，第一配合部133的邻近安装板本体132中心的一侧设有两个第二限位部134，两个第二限位部134可沿安装板本体132的径向相对。安装时，第一子卡合部2111和第二子卡合部2121分别配合在对应的容置部131内，第一卡扣2113与第二限位部134的侧壁贴合。由此，可以避免第二壳体21绕安装板13的中心轴线转动，以将第二壳体21牢靠地固定在安装板13上。
如图6至图8所示，第一子壳体211还包括第一安装柱2115。如图9至图11所示，第二子壳体212还包括第二安装柱2125，第二安装柱2125与第一安装柱2115对应设置。紧固件的两端分别与第一安装柱2115和第二安装柱2125相连。
安装时，将第一子壳体211和第二子壳体212连接之后，紧固件的两端分别伸入第一安装柱2115和第二安装柱2125内。由此，可以提高第一子壳体211和第二子壳体212的连接可靠性，避免第一子壳体211和第二子壳体212脱离配合。
在一些实施例中，第一子壳体211设置有至少一个第一连接部213，第二子壳体212中设有至少一个第二连接部214，第二连接部214与第一连接部213相配合，以提高第一子壳体211与第二子壳体212的连接处的防水性能。
例如，第一连接部213和第二连接部214中的一个具有凸起，第一连接部213和第二连接部214中的另一个具有凹槽。
以下以第一连接部213具有凹槽，第二连接部214具有凸起为例，对第二连接部214和第一连接部213的结构进行说明。
如图13至图16所示，第一连接部213设在第一子壳体211的边缘，且沿第一子壳体211的轴向延伸。第二连接部214设在第二子壳体212的边缘，且沿第二子壳体212的轴向延伸。安装时，将第二连接部214配合在第一连接部213内，以使第一子壳体211的端面与第二子壳体212的端面贴合，减小第一子壳体211和第二子壳体212的连接处的间隙，从而可以提高第一子壳体211与第二子壳体212的连接处的密封性。
这样，避免外部液体(如水)经上述连接处进入第二壳体21内，实现了对第二壳体21内的压缩机22、风机组件25和蒸发器23的防水保护，增强了热泵热水器100的防水效果。并且，可以保证第一子壳体211与第二子壳体212的光滑连接，以使第一子壳体211和第二子壳体212的外观装配效果好。
如图14所示，第一连接部213包括第一段2131和第二段2132。第一段2131沿第一壳体11的轴向延伸。第二段2132的一端与第一段2131相连，第二段2132的另一端沿朝向第一壳体11中心的方向延伸。
如图16所示，第二连接部214包括第四段2141和第五段2142。第四段2141沿第一壳体11的轴向延伸，第四段2141配合在第一段2131内。第五段2142的一端与第四段2141相连，第五段2142的另一端沿朝向第一壳体11中心的方向延伸，第五段2142配合在第二段2132内。
在一些实施例中，第二段2132沿水平方向朝向远离第一段2131的方向延伸，此时第一连接部213形成第一折弯部。第五段2142沿水平方向朝向远离第四段2141的方向延伸，此时第二连接部214形成第二折弯部。
由此，当第二连接部214嵌入第一连接部213内后，第一连接部213和第二连接部214可以进一步实现对第一子壳体211和第二子壳体212的密封，使得外部液体难以渗入第二壳体21内，从而加强了热泵热水器100的防水效果。
参照图17和图19，在一些实施例中，第二壳体21还包括顶盖3，顶盖3盖设在第一子壳体211和第二子壳体212的远离水箱组件1的一侧(如上侧)。顶盖3包括彼此相连的顶盖延伸段31和顶盖本体32，顶盖本体32与第二壳体21的顶部相对，顶盖延伸段31 沿远离顶盖本体32的方向倾斜向下延伸，且顶盖延伸段31的自由端的端面(即顶盖3的底壁)与第二段2132的外侧壁止抵。
由此，顶盖3覆盖了第一连接部213与第二连接部214的配合处的上部，对第一子壳体211和第二子壳体212能起到保护作用，使得第一连接部213与第二连接部214的配合处的上部具有双重防水性能，有利于增强热泵热水器100的防水效果。
在一些实施例中，如图14和图16所示，第一连接部213还包括第三段2133。第三段2133的一端与第二段2132的另一端相连，第三段2133的另一端沿远离第二段2132的方向倾斜延伸。第二连接部214还包括第六段2143。第六段2143的一端与第五段2142的另一端相连，第六段2143的另一端沿远离第二连接部214端的方向倾斜延伸，第六段2143配合在第三段2133内。
在一些实施例中，第三段2133沿远离第二段2132的的方向倾斜向上延伸。第三段2133的长度可以小于顶盖本体32到第二段2132的距离。同样地，第六段2143沿远离第五段2142的方向倾斜向上延伸。此时，使得第一连接部213和第二连接部214的邻近顶盖3的一端具有多个折弯部。由此，进一步实现了对第一子壳体211和第二子壳体212的密封，增强了第二壳体21的防水性能。
可以理解的是，安装板13位于第一壳体11和第二壳体21之间。在一些实施例中，安装板13的侧壁伸入第二壳体21内。如图17和图18所示，安装板13的第一配合部133向上延伸构成了侧壁，且侧壁的直径小于第二壳体21的直径。安装时，第二壳体21位于安装板13的侧壁的外侧，使得第一连接部213和第二连接部214的下部具有双重防水性能，增强了热泵热水器100的防水效果。
在一些实施例中，参照图18，沿第一壳体11的轴向，安装板13的侧壁的自由端(即第一配合部133的顶端)高于第一段2131的自由端(即第一段2131的底端)。例如，在第一子壳体211与第二子壳体212的连接处，安装板13的侧壁的自由端的端面位于第一段2131的自由端上方，此时安装板13的侧壁的自由端与第一段2131的自由端在第二壳体21的轴向方向上有一部分重叠，即便外部液体从第一连接部213和第二连接部214的配合处的下部渗入第二壳体21内，安装板13的侧壁可以阻挡外部液体进一步渗入第二壳体21内，从而进一步加强了热泵热水器100的防水效果。
在一些实施例中，第一连接部213和第二连接部214均为两个，两个第一连接部213分别位于第一子壳体211的周向的两端，两个第二连接部214分别位于第二子壳体212的周向的两端。通过两个第一连接部213与两个第二连接部214配合，进一步保证了第一子壳体211与第二子壳体212连接处的防水效果。
如图20至图23所示，风机组件25包括蜗壳251、蜗壳延伸部252、风轮255。蜗壳251设于蒸发器23的远离压缩机22的一侧，蜗壳251具有第二进风口2511和第二出风口2512。第二进风口2511面向蒸发器23设置。第二出风口2512与第一出风口302沿第二壳体21的轴向相对且连通。从第一进风口301进入第二壳体21内部的空气适于流经第二进风口2511进入风机组件25后，从第二出风口2512和第一出风口302排出。
在一些实施例中，如图21和图22所示，蜗壳延伸部252的一端与第二出风口2512相连，蜗壳延伸部252的另一端与第一出风口302相对，从第二出风口2512朝向第一出风口302的方向(即上下方向)、蜗壳延伸部252朝向靠近蒸发器23的方向倾斜设置。
在一些实施例中，风轮255设在蜗壳251内，从第一进风口301进入第二壳体21内部的空气流经蒸发器23并与蒸发器23换热后，经第二进风口2511进入蜗壳251并通过第二出风口2512从第一出风口302排出。
在一些实施例中，蜗壳延伸部252朝向蒸发器23所在的一侧倾斜设置。这样，一方面可以使蜗壳延伸部252在远离蒸发器23的另一侧形成避让空间，便于第二壳体21的设置。另一方面，可以利用蒸发器23周边的部分空间，以使热泵装置2内部的结构更加紧凑，并且便于将第二出风口2512与第一出风口302连通，以增加第一出风口302处的出风量。
由此，在蜗壳251的第二出风口2512处设置倾斜的蜗壳延伸部252，可以充分利用蒸发器23顶部的空间，便于增加第二出风口2512的面积，有利于使第二出风口2512与第 一出风口302相对，增加第二出风口2512处的出风量，以使空气能够及时排出，提高第二壳体21内部空间的利用率。并且，可以避免第二壳体21在与安装板13装配时，第二出风口2512与第二壳体21互相干涉，影响第二壳体21的装配的效率。
如图21所示，蜗壳延伸部252包括开口段253和连接段254，连接段254与开口段253连接，且连接段254比开口段253更靠近蜗壳251。开口段253的一端与第一出风口302相对。例如，开口段253的横截面为圆形。连接段254的一端与开口段253的另一端连接，连接段254的另一端与第二出风口2512连接。例如，连接段254的所述另一端的横截面形状大致为矩形。
在一些实施例中，第二出风口2512流出的空气依次经过连接段254和开口段253，再从第一出风口302流出。开口段253的横截面形状与第一出风口302的形状相适配，由此，有利于增加蜗壳延伸部252的出风面积。连接段254的远离开口段253的一端的横截面的形状(如矩形)与第二出风口2512的形状相适配。这样，能够增加第二出风口2512的出风面积，从而增大蜗壳251的出风量，有利于提高蒸发器23的换热效率。
如图22所示，连接段254包括沿蜗壳251的第二出风口2512的周向依次连接的第一面2541、第二面2542、第三面2543、第四面2544、第五面2545和第六面2546。第一面2541分别与蒸发器23以及第二面2542连接。第四面2544与蒸发器23的面向风机组件25的一侧表面相对。第六面2546分别与第五面2545以及蒸发器23连接，第六面2546与第一面2541相对。
例如，第一面2541的一侧与蒸发器23连接，第二面2542的一侧与第一面2541的另一侧连接，第三面2543的一侧与第二面2542的另一侧连接，第四面2544的一侧与第三面2543的另一侧连接，第四面2544与蒸发器23的面向风机组件25的一侧表面相对，第五面2545的一侧与第四面2544的另一侧连接，第六面2546的一侧与第五面2545的另一侧连接，第六面2546的另一侧与蒸发器23连接，第六面2546与第一面2541相对。且至少第二至第五面2545沿第二出风口2512朝向第一出风口302的方向(即由下到上的方向)朝向靠近蒸发器23倾斜延伸。
需要说明的是，第一面2541至第六面2546的外周面分别为不规则的曲面。例如，第四面2544邻近开口段253的部分的曲率半径大于第四面2544邻近第二出风口2512部分的曲率半径。
第二出风口2512的端面包括第一连接段、第二连接段、第三连接段、第四连接段、第五连接段和第六连接段，第一连接段的两端的端点沿开口段253的中心轴线的方向(即上下方向)与开口段253对应点的连线围成的区域构成第一面2541。第二面2542至第六面2546依次类推。由此，第一面2541至第六面2546从第二出风口2512朝向开口段253倾斜延伸，使蜗壳延伸部252根据第二出风口2512的形状构成连接段254的下端面，以保证连接段254下端面的横截面积与第二出风口2512相适应，从而增加蜗壳251的出风量。
如图22所示，第二出风口2512的远离蒸发器23的两个角处分别具有第一圆角256和第二圆角257，第二面2542和第三面2543连接在第一圆角256处，第五面2545连接在第二圆角257处。即所述第二连接段和所述第三连接段为第一圆角256，所述第五连接段为第二圆角257。第一圆角256和第二圆角257由蜗壳251在成形过程中形成。
在一些实施例中，第二面2542、第三面2543和第五面2545在朝向开口段253延伸时，蜗壳延伸部252的横截面积减小，以将空气引导至开口段253。由此，第一圆角256和第二圆角257的设置，便于降低空气在蜗壳251内部流动的阻力，且便于第二面2542、第三面2543和第五面2545的设置，以使连接段254与第二出风口2512相适配。
在一些实施例中，如图23所示，第一面2541沿第二出风口2512至开口段253的方向朝向蜗壳251的中心(如图23中风轮255所在的一侧)倾斜延伸。由此，将第一面2541倾斜设置，能够避免开口段253对第二壳体21的安装产生干涉并且提高第二壳体21内部空间的利用率。
如图23所示，第一面2541的倾斜角度为β。即第一面2541在第一截面上的正投影与开口段253的中心轴线在第一截面上的正投影的夹角为β，β满足：β≤3°。也即第一面 2541在蒸发器23上的正投影与开口段253的中心轴线之间的角度为β，β满足：β≤3°。
需要说明的是，所述第一截面为垂直于风轮255的中心轴线方向的风机组件25的横截面。风轮255的中心轴线如图24所示的虚线N-N。
可以理解的是，夹角β越大，第一面2541的倾斜角度越大，空气在流经第一面2541时的方向变化越大。因此空气可能在第一面2541附近产生涡流，从而影响蜗壳延伸部252内空气的流动速率，降低第二出风口2512的出风量。
由此，限定第一面2541与开口段253中心轴线之间的夹角，以使第一面2541位于预设位置范围内，便于蜗壳延伸部252与第一出风口302相对，保证了出风效果。
在一些实施例中，如图24所示，第四面2544沿第二出风口2512向开口段253的方向朝向蒸发器23倾斜延伸，第四面2544的倾斜角度为α，α满足：α≤5°。即第四面2544在第二截面上的正投影与开口段253的中心轴线在所述第二截面上的正投影的夹角为α，α满足：α≤5°。
需要说明的是，所述第二截面为过风轮255的中心轴线的纵向平面，且该纵向平面沿开口段253的中心轴线方向延伸。也即，所述第二截面为过图23中虚线M-M的风机组件25的截面。
可以理解的是，夹角α越大，第四面2544的倾斜角度越大。受到第四面2544倾斜角度的影响，空气可能在第四面2544附近产生涡流，从而影响蜗壳延伸部252内空气的流动速率，降低第二出风口2512的出风量。
由此，限定第四面2544与开口段253的中心轴线之间的夹角，能够提高蜗壳延伸部252的出风效果，且有效降低蜗壳延伸部252对空气流动的阻力，保证第二出风口2512的空气能够及时从蜗壳延伸部252排出。
参照图22和图25，蒸发器23还包括避让部231，蜗壳延伸部252部分位于避让部231内。避让部231被配置为避让蜗壳延伸部252。避让部231在水平面上的第一正投影面积与第二正投影面积之比为A，第二正投影面积为蜗壳延伸部252的远离第二出风口2512的一端(即开口段253)在水平面上的正投影面积，A满足：1/6≤A≤1/2。
可以理解的是，避让部231与开口段253的正投影面积之比A越小，则避让部231的空间越小。此时，蜗壳延伸部252不能合理地利用蒸发器23的内部空间，使蒸发器23和蜗壳251的整体体积大，不利于热泵装置2的小型化设计。并且避让部231空间不足，还会影响开口段253截面的面积大小，从而影响出风效果。
避让部231与开口段253的正投影面积之比A越大，则开口段253与第二出风口2512在水平面上的正投影相交的面积越小。因此，可能会干扰第二出风口2512出风，从而降低第二出风口2512的出风效率。
由此，限定避让部231与开口段253在水平面的正投影面积之比，便于将第一出风口302与开口段253相对设置，避免第一出风口302对开口段253的安装产生干涉，并且能够提高蜗壳延伸部252、蜗壳251和蒸发器23的结构紧凑性，增大蜗壳251内部的空间。另外，能够保证蜗壳延伸部252的出风效率，使得空气能够快速地从第二出风口2512流向第一出风口302，从而从第一出风口302排出。
如图26所示，蜗壳延伸部252的远离开口段253的一端(即底端)与蒸发器23的连接处通过第三圆角258过渡。空气在流出第二出风口2512时，能够在蜗壳延伸部252与蒸发器23的连接处，通过第三圆角258流向蜗壳延伸部252，以此增加所述连接处对空气的导向性，避免空气在该连接处流动方向变化大，而影响蜗壳延伸部252的出风效率。
如图21和图24所示，蜗壳251包括沿风轮255的中心轴线方向相互连接的第三壳体2513和第四壳体2514。蒸发器23包括用于蒸发的管路和安装管路的侧板。第三壳体2513与蒸发器23的侧板连接，且第三壳体2513与侧板为一体件。第四壳体2514连接在第三壳体2513的远离蒸发器23的一侧。由此，第三壳体2513与蒸发器23的侧板一体成型，可以减小热泵装置2部件的数量，有利于提高蜗壳251的安装效率。
如图26和图29所示，蜗壳251的第二进风口2511连通蒸发器23的侧板，空气经过蒸发器23的管路换热后，到达蒸发器23的侧板所在的位置，再经第二进风口2511进入 蜗壳251。由此，第三壳体2513与蒸发器23的侧板一体成型，能够保证蜗壳251与蒸发器23之间的密封性，有利于增加第二进风口2511的进风量。
如图24所示，沿蒸发器23的厚度方向也即风轮255的中心轴线方向，第三壳体2513的宽度与第四壳体2514的宽度之比为B，B满足：3/7≤B≤1。
可以理解的是，若第三壳体2513与第四壳体2514之间的宽度之比B小于3/7，则不能充分地利用蒸发器23的内部空间，且可能降低第三壳体2513与蒸发器23连接的结构强度。若第三壳体2513与第四壳体2514之间的宽度之比B大于1，则第三壳体2513容易与蒸发器23内部的结构产生干涉，影响第二出风口2512的出风量。
由此，通过限定第三壳体2513与第四壳体2514的宽度之比，以使第三壳体2513能够合理的利用侧板的空间，便于蜗壳延伸部252与第一出风口302相对，保证第三壳体2513与蒸发器23的连接强度，且增大蜗壳251的内部空间，提高蜗壳251的进风量和出风量。
在一些实施例中，如图20所示，顶盖3具有第一进风口301和第一出风口302，第一进风口301和第一出风口302均与第二容纳腔20连通。
在一些实施例中，如图2和图3所示，第一进风口301和第一出风口302分别位于蒸发器23的两侧，第一出风口302和风机组件25位于蒸发器23的同一侧且与风机组件25连通，从第一进风口301进入第二壳体21内部的空气适于流经蒸发器23并与蒸发器23换热后经风机组件25从第一出风口302排出。
在一些实施例中，第一进风口301和第一出风口302关于顶盖3为非中心对称布置，也即第一进风口301与第一出风口302不在顶盖3的径向方向相对设置。这样，能够避免第一进风口301受到电控盒26等部件的干扰，增加进风空间和进风效率。并且从第一进风口301进入第二壳体21内部的空气在流经蒸发器23时需要经过预设角度，再从第一出风口302处流出，能够延长空气从第一进风口301流向第一出风口302的流动路径，以使空气与压缩机22、电控盒26、蒸发器23等充分换热。
如图27所示，第一进风口301的中心和第一出风口302的中心分别与顶盖3的中心的连线之间的夹角为γ，γ满足：80°≤γ＜180°。也即，第一进风口301的中心与顶盖3的中心连接形成第一线段，第一出风口302的中心与顶盖3的中心连接形成第二线段，第一线段和第二线段沿第二壳体21的轴向方向在顶盖3上的正投影构成的夹角为γ。
可以理解的是，夹角γ越小，则第一进风口301与第一出风口302距离越近。若夹角γ小于80°，则容易导致第一进风口301与第一出风口302互相干涉，影响热泵热水器100的进风和出风效果。还可能会使第一进风口301与第一出风口302分别与第二进风口2511的连线的夹角小，增加空气在第二壳体21内部流动的阻力。并且，不便于第二壳体21内部电控盒26和压缩机22等部件的设置。
由于从第一进风口301进入第二壳体21内部的空气经过蒸发器23之后，再经由第二进风口2511和第二出风口2512，最终从第一出风口302流出。因此在第二进风口2511的中心位置固定的情况下，夹角γ越大，空气在第二壳体21内部的流经的路径越短，对第二壳体21内压缩机22和电控盒26的散热效果越弱。并且，空气在第二壳体21内部停留时间变短，降低了蒸发器23的蒸发效率。
若夹角γ等于180°，则第一进风口301与第一出风口302关于第二壳体21的中心对称设置。此时第一进风口301可能部分位于电控盒26上方，导致进风空间小，从第一进风口301进入第二壳体21内部的空气受到电控盒26的干扰，不能顺利到达蒸发器23所在的位置处，从而导致空气的流失。
例如，第一进风口301的中心和第一出风口302的中心分别与顶盖3的中心的连线之间的夹角γ＝105°。
由此，通过限定第一进风口301与第一出风口302之间的夹角γ，一方面能够保证第一进风口301的进风效果，从而保证蒸发器23工作所需要的风量，以提高蒸发器23的换热效率。另一方面能够保证第一出风口302的出风效果，有利于提高空气在第二壳体21内部流动的速率，使空气能够快速带走电控盒26和压缩机22等工作产生的热量，有效降低 热泵热水器100的能耗。
在一些实施例中，如图20和图27所示，第一进风口301与压缩机22沿热泵热水器的轴向方向相对设置，且第一进风口301与压缩机22间隔设置。也即第一进风口301与压缩机22在第二壳体21的轴向方向相对。从第一进风口301进入第二壳体21的空气先经过压缩机22再流向蒸发器23和电控盒26。以此，可以避免电控盒26对第一进风口301的遮挡，增加第二壳体21进风量，实现对压缩机22的降温。
在一些实施例中，如图26、图28和图29所示，在蒸发器23的宽度方向上，进风口2511位于蒸发器23的靠近电控盒26的一侧。例如，第二进风口2511和电控盒26位于蒸发器23的两侧且相对设置。从第一进风口301进入第二壳体21内部的空气先经过压缩机22，再经过电控盒26和蒸发器23，并最终流向第二进风口2511。
以此，保证在风机组件25的作用下，第二壳体21内部的空气从蒸发器23的靠近电控盒26的一侧(如图28所述的S2侧)流向第二进风口2511，避免空气从蒸发器23的靠近压缩机22的一侧(如图28所述的S1侧)流向第二进风口2511。这样，使得空气所流经蒸发器23的面积增大，增加了蒸发器23的受风面积。并且可以保证空气与电控盒26充分接触，实现对电控盒26的散热，从而保证电控盒26的工作效率。
如图29所示，第二进风口2511的中心位于第一中心平面邻近安装板13的一侧。所述第一中心平面为所述蒸发器23的高度方向上的中心平面，且所述第一中心平面沿蒸发器23的中心轴线方向延伸。
需要说明的是，所述蒸发器23的高度方向为图29所示的上下方向，所述蒸发器23的宽度方向为图29所示的左右方向。
由此，将第二进风口2511的中心设置于蒸发器23的所述第一中心平面以下，且靠近所述电控盒26设置，能够延长空气从第一进风口301流向第一出风口302的流动路径，充分增加蒸发器23的受风面积，以此增加蒸发器23的换热效率。
如图28所示，沿朝向压缩机22的方向，电控盒26与蒸发器23之间的距离逐渐增大，电控盒26与蒸发器23之间呈夹角θ，θ满足：15≤θ≤30°。第一进风口301与压缩机22相对，空气从第一进风口301进入第二壳体21内后，流向蒸发器23和蒸发器23与电控盒26之间的空间内，以便于电控盒26的散热。
可以理解的是，夹角θ越小，则电控盒26与蒸发器23之间的进风量越小，可能导致电控盒26的散热能力降低，蒸发器23的换热能力减弱。电控盒26与蒸发器23之间的夹角θ越大，则流向蒸发器23的空气会受到电控盒26的阻挡，越容易在电控盒26的表面产生紊流，从而造成空气的流失，使蒸发器23的进风量减小，并进一步影响蒸发器23的换热效果。
例如，沿朝向压缩机22的方向、电控盒26与蒸发器23之间的距离逐渐增大，电控盒26与蒸发器23之间的夹角θ＝25°。由此，限定电控盒26与蒸发器23之间的夹角θ，可以增加蒸发器23靠近电控盒26一侧的进风量，提高蒸发器23的换热能力和换热效率，并且可使大量空气经过电控盒26表面，提升电控盒26内的电控板的降温效果，便于对电控盒26进行散热。
在一些实施例中，如图30至图32所示，第二壳体21形成有第一开口217，第一开口217可以形成在第二壳体21的侧壁上。热泵装置2还包括滤网组件4，滤网组件4穿设第一开口217设于第一开口217内，滤网组件4与第一进风口301相对。滤网组件4被配置为过滤从第一进风口301进入第二壳体21内部的空气中的杂质。
在风机组件25的作用下，从第一进风口301进入第二壳体21内部的空气先经过滤网组件4的过滤后，再流经压缩机22、蒸发器23和风机组件25等，最终从第一出风口302流出。
可以理解的是，第一开口217的设置便于滤网组件4的安装。滤网组件4的设置，能够避免空气中的杂质例如颗粒物等进入蒸发器23中，且在蒸发器23的表面停留而造成蒸发器23的堵塞，以此提高蒸发器23的换热效率，增加第二壳体21内部蒸发器23和压缩机22等部件的使用寿命。
在一些实施例中，如图33和图34所示，滤网组件4包括滤网41和支架42。滤网41设于支架42上，支架42被配置为对滤网41进行支撑。支架42设置在第二壳体21的第一开口217处，且与第二壳体21相连接。例如，支架42与第二壳体21一体成型。支架42远离第一开口217的部分朝向第一进风口301的中心延伸，以与第一进风口301相对。
可以理解的是，滤网41安装于支架42之后，沿第二壳体21的轴向方向，第一进风口301、滤网41和支架42相对。支架42的设置能够便于滤网41的安装，且提高滤网41的稳定性。
在一些实施例中，如图35所示，滤网41包括第二配合部411和第三连接部412。第二配合部411靠近第一开口217的一侧表面与第二壳体21的外周面平齐。第三连接部412的一端与第二配合部411连接，第三连接部412的另一端穿设第一开口217伸入第二壳体21内。
滤网41的形状可以与支架42的形状相适配，以提高滤网41的安装效率，充分过滤进入第二壳体21内部的空气。并且，便于用户在第一开口217处取出滤网41，以对滤网41进行更换和清理，来保证第一进风口301处的进风量。
在一些实施例中，如图34至图37所示，支架42和滤网41中的一个上设有第二卡合部423，支架42和滤网41中的另一个上设有第二卡扣414。
例如，支架42设置有第二卡合部423，第二卡合部423设于支架42的邻近第一开口217的一侧。第三连接部412设有第二卡扣414，第二卡扣414设于滤网41邻近第二配合部411的一侧。第二卡扣414与第二卡合部423相配合，以将滤网41与支架42相固定。
在一些实施例中，第二卡扣414的自由端朝向第二壳体21的中心倾斜延伸，且第二卡扣414在第二壳体21的轴向方向可发生形变，以便于第二卡扣414与第二卡合部423的配合。由此，第二卡合部423可以形成对第二卡扣414的限位，使得滤网41与支架42可拆卸连接，便于后期更换和清理滤网41，降低滤网组件4的使用成本。
在一些实施例中，如图34所示，支架42上形成有通孔424。通孔424设于支架42的远离第一开口217的一端，且通孔424与第一进风口301相对。滤网41的至少部分与通孔424相对，从第一进风口301进入第二壳体21内部的空气适于通过滤网41的所述至少部分以及通孔424。
在一些实施例中，如图34所示，支架42包括支架本体421和安装槽422。安装槽422设置于支架本体421的沿第二壳体21的周向方向的至少一侧。安装槽422沿第二壳体21的径向方向朝向第一进风口301的中心延伸。安装槽422被配置为对滤网41进行导向。
如图35所示，滤网41还包括导向筋413，导向筋413设置于第三连接部412的沿第二壳体21的周向方向的至少一侧。导向筋413沿第二壳体21的径向方向朝向第二壳体21的中心延伸。导向筋413与安装槽422相配合，以将滤网41安装于支架42。
在滤网41与支架42装配的过程中，滤网41从第一开口217处沿着安装槽422伸入第一开口217内，以完成与支架42的配合。由此，安装槽422和导向筋413的设置，可以形成对滤网41的限位，增加装配过程中对滤网41的导向性，以及安装后滤网41的稳定性，有利于提高滤网41与支架42的装配效率。
在一些实施例中，如图35所示，滤网还包括推拉部415，推拉部415设置于第二配合部411靠近第二壳体21的顶部的一侧，且沿第二壳体21的周向方向延伸。在第二壳体21的轴向方向上，推拉部415朝向水箱组件1的方向凹入。以此，推拉部415具有防滑的作用，便于用户通过推拉部415打开第二配合部411或者取出滤网41。
在一些实施例中，如图31所示，第二壳体21上还设有第二开口218，第二开口218位于第一开口217的邻近第二壳体21的顶部的一侧。第二开口218在第二壳体21的轴向方向与第一开口217连通，且第二开口218与推拉部415相对设置。第二开口218的设置可以进一步便于用户取出滤网41。
在一些实施例中，滤网组件4满足以下之一：滤网组件4与第二壳体21可拆卸连接，或，滤网组件4包括滤网41和支架42，滤网41可拆卸地安装在支架42上，支架42与第二壳体21相连接。
在滤网组件4与第二壳体21可拆卸连接的情况下，安装槽可形成于第二壳体21的侧壁上，以便于滤网组件4安装和拆卸，提高安装效率。滤网组件4整体可沿安装槽装配于第二壳体21。在需要更换滤网组件4时，将滤网组件4整体沿安装槽取下。这样，滤网组件4和第二壳体21可分别进行制造，能够降低加工难度。
在滤网组件4包括滤网41和支架42的情况下，滤网41可拆卸地设在支架42上，支架42可与第二壳体21一体成型，以提高支架42的结构强度。在需要更换滤网41时，将滤网41沿支架42取下，以便于滤网41的更换，降低后期使用和维护的成本。
