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。
通常，热泵热水器100的第一进风口和第一出风口关于顶盖为中心对称分布，即第一进风口和第一出风口的圆心连线经过顶盖的中心。这样进入第二壳体21内部的空气可能会受到第二壳体21内部的电控盒26的干扰。
并且，常见的蜗壳的第二出风口的位置设计不合理，导致蜗壳占用第二壳体21内部较大空间，使得第二壳体21内部的空间利用率低，不利于热泵热水器100的集成化和小型化设计。
为解决上述问题，本公开一些实施例提供一种热泵热水器100，热泵热水器100的第一进风口和第一出风口关于顶盖为非中心对称分布，且第一进风口与压缩机22相对设置，以增大进风空间，避免第二壳体21内部空气流动受到干扰。
蜗壳的第二出风口处设置有蜗壳延伸部，以连通第二出风口和第一出风口。蜗壳延伸部朝向蒸发器23和风轮的中心倾斜设置，以减少对第二壳体21内部空间的占用，并且避免了对第二壳体21的安装造成影响。
在一些实施例中，如图20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。
在一些实施例中，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中的另一个设有卡合部215，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包括卡合部215，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，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，卡合部215的一端朝第二壳体21的中心轴线方向延伸，卡合部215的一端的另一端与第二壳体21相连接。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 配合部133。安装板本体132与第一壳体11相连，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，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。
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，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，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，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。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位于所述多个卡合部215中的相邻两个卡合部215之间。装配时，密封件216与配合部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，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中的一个上设有卡扣2113，安装板13上设有第二限位部134，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的一端设有两个卡扣2113。两个卡扣2113分别位于第一子壳体211的周向的两端，且两个卡扣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，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，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23和图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至图4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100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和图28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所示的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所示的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。
如图30和图31所示，热泵热水器100还包括滤网组件4。滤网组件4设在第二壳体21内，且滤网组件4与第一进风口301相对。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。
在一些实施例中，如图32至图34所示，底座28具有第一接水槽281，第一接水槽281设于底座本体上且位于蒸发器23下方，第一接水槽281被配置为收集蒸发器23的管路产生的冷凝水。
在一些实施例中，如图34所示，底座28还具有排水槽283和排水孔285。排水槽283的一端与第一接水槽281相连通，排水槽283远离第一接水槽281的另一端与排水孔285相连通。第一接水槽281中收集的冷凝水可沿第一接水槽281流向排水槽283，并最终从排水孔285排出第二容纳腔20。
由此，在蒸发器23下方设置第一接水槽281以收集蒸发器23的管路表面产生的冷凝水，且使第一接水槽281收集的冷凝水经过排水槽283和排水孔285流出第二容纳腔20。这样能够避免冷凝水的随意流动对热泵装置2造成影响，并且，集成式的排水结构也能够显著提升冷凝水的收集效率和排放效率。
可以理解的是，底座28上对应的蒸发器23的管路之外的容易产生冷凝水的区域处也可以设置接水槽结构。所述接水槽结构连通排水槽283，使得各区域产生冷凝水经过所述接水槽结构收集后，均可以从排水槽283排出。这样，进一步保证了对冷凝水的收集效果和排放效果。
在一些实施例中，底座28还包括多个第一加强筋2811，所述多个第一加强筋2811设于第一接水槽281的底面上。所述多个第一加强筋2811相互平行设置，并构成装配位，以安装蒸发器23。这样，蒸发器23设置于第一加强筋2811构成的所述装配位，保证了蒸发器23在底座28上的稳定。
进一步地，所述多个第一加强筋2811均沿同一方向设置并指向排水槽283，以此能够保证第一接水槽281的强度，以对蒸发器23进行支撑，还能够对冷凝水起到引流的作用，引导第一接水槽281中的冷凝水尽快流向排水槽283，能够显著提升第一接水槽281的接水与排水效果。
如图32至图34所示，底座28还包括第二接水槽282，第二接水槽282位于蜗壳251的下方，且，第二接水槽282设于第一接水槽281的一侧并与排水槽283相连通。
可以理解的是，由于蜗壳251靠近蒸发器23设置，蜗壳251的表面也会因蒸发器23的运行而产生冷凝水，蜗壳251表面的冷凝水沿蜗壳251汇集至蜗壳251的底部。在蜗壳251的底部设置第二接水槽282，可收集蜗壳251表面产生的冷凝水，第二接水槽282所收集的冷凝水可沿第二接水槽282流向排水槽283并最终从排水孔285排出第二容纳腔20。
在一些实施例中，第二接水槽282的形状与蜗壳251的形状相配合，以保证对蜗壳251表面产生的冷凝水的收集效果。如图32和图34所示，蜗壳251的下表面为弧形。为了使第二接水槽282与弧形的蜗壳251相配合第二接水槽282为截面呈梯形的弧形槽。或者，第二接水槽282包括水平设置的底面，以及与底面相连接的弧形侧面。弧形侧面与蜗壳251的弧面相匹配，二者可以同圆心不同直径的两段弧面。
在一些实施例中，底座28还包括多个第二加强筋2821，所述多个第二加强筋2821设置于第二接水槽282的底面和侧面。与第一加强筋2811不同的是，所述多个第二加强筋 2821包括相互垂直的至少一个横向筋和至少一个纵向筋，即所述多个第二加强筋2821横竖交错设置。以此，能够提升第二接水槽282的结构强度，实现对蜗壳251的支撑，并且确保蜗壳251与第二接水槽282之间能够形成间隙，保证了冷凝水的正常流动。
如图34和图37所示，在一些实施例中，底座28还包括导水槽284，导水槽284设置于第二接水槽282的一侧。例如，导水槽284设置于第一接水槽281和第二接水槽282之间。导水槽284与第二接水槽282和排水槽283相连通。第二接水槽282中的冷凝水可经过导水槽284流向排水槽283。
在一些实施例中，蜗壳251的第三壳体2513向蒸发器23所在的方向延伸，且与蒸发器23的侧板连接，且第三壳体2513与蒸发器23的侧板为一体件。导水槽284还可以位于蒸发器23的侧板的底部，此时导水槽284不仅被配置为中转第二接水槽282的冷凝水，还被配置为收集蒸发器23的侧板产生的冷凝水，并将冷凝水传递至排水槽283中。
在一些实施例中，如图35、图37以及图39所示，从靠近第一接水槽281的一端至靠近排水孔285的一端，排水槽283在底座28上的正投影的宽度呈减小趋势。进一步地，为了避免排水槽283中的冷凝水在排水槽283中长时间堆积与停留，使排水槽283中的冷凝水快速排出，排水槽283的底面相对水平面向靠近水箱本体12的一端(即下端)倾斜设置，也即从靠近第一接水槽281的一端至靠近排水孔285的一端，排水槽283的底面的高度在热泵热水器100的轴向上逐渐降低。例如，排水槽283底面的倾斜角度为θ，θ满足1°≤θ≤3°。
如图35至图38所示，底座28还包括多个遮挡柱2831，所述多个遮挡柱2831设置在排水槽283的靠近排水孔285的位置处。所述多个遮挡柱2831能够对冷凝水中的大体积异物进行阻挡，可有效防止异物阻塞排水孔285影响冷凝水的正常排出。实际使用时操作人员可定期打开第二壳体21对遮挡柱2831旁侧被阻拦的异物或大体积颗粒进行清洗，进而确保排水槽283的正常使用。
在一些实施例中，为了方便操作人员及时了解各接水槽及排水槽283中的水位情况，例如，第一接水槽281内还设有水位传感器，水位感应器被配置为检测第一接水槽281内的水位情况。当排水槽283无法正常排水且导致第一接水槽281内的冷凝水水位位于水位阈值范围外时，水位传感器可发出报警信号，以提醒操作人员及时检查第一接水槽281及排水槽283的情况，保证热泵热水器100的正常运行。
本领域的技术人员将会理解，本发明的公开范围不限于上述具体实施例，并且可以在不脱离本申请的精神的情况下对实施例的某些要素进行修改和替换。本申请的范围受所附权利要求的限制。
