具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请实施例的洗涤电器1。
如图1-图5所示，根据本申请实施例的洗涤电器1包括内胆100、风道组件200和热泵系统300。
内胆100具有进风口101和出风口102，风道组件200包括第一风道210，第一风道210的进口与出风口102连通，第一风道210的出口与进风口101连通。热泵系统300包括压缩机310、节流装置320、风冷冷凝器330和蒸发器340，蒸发器340的至少一部分设在第一风道210内，以便于蒸发器340与流经的气体进行热量交换。其中，风道组件200还包括第二风道220，第二风道220的进口与出风口102连通，第二风道220的出口与第一风道210连通，风冷冷凝器330的至少一部分设在第一风道210内且在气体的流动方向上位于第二风道220的下游，以便于风冷冷凝器330与流经的气体进行热量交换。
具体而言，在气体的流动方向上，第二风道220的出口与第一风道210的连通处位于风冷冷凝器330的上游且位于蒸发器340的下游。也就是说，第一风道210内的气 体经过蒸发器340的除湿作用后，可以与第二风道220内的气体汇合，并在通过进风口101流入内胆100之前，第一风道210和第二风道220内的气体都会经过风冷冷凝器330进行加热。
这里需要理解的是，“风冷冷凝器330在气体的流动方向上位于第二风道220的下游”是指从内胆100流出的气体先流经第二风道220，再流经风冷冷凝器330。“第二风道220的出口与第一风道210的连通处在气体的流动方向上位于风冷冷凝器330的上游”是指从内胆100流出的气体先流经第二风道220的出口与第一风道210的连通处，再流经风冷冷凝器330。
根据本申请实施例的洗涤电器1，通过设置热泵系统300，可以利用热泵系统300吸收外界环境中的热量，对风道组件200内流通的气体或洗涤电器1内的洗涤液进行加热，将低品位的能量转换成高品位热能后，释放于气体或洗涤液中，达到高效、低能耗制热的目的。相比电加热的方式，热泵系统300通过压缩机310、节流装置320、风冷冷凝器330和蒸发器340的作用，热泵系统300内的制冷剂可以经历压缩、冷凝放热、节流膨胀、蒸发吸热的过程，将低品位的能量转换成高品位热能后，释放于风道组件200内的气体或洗涤电器1的洗涤液中，达到高效、低能耗制热的目的，节能效果显著，可大幅度降低洗涤电器1的使用能耗。
并且，通过在风道组件200内设置第一风道210和第二风道220，内胆100流出的高湿气体可以通过出风口102流入第一风道210和第二风道220。一部分高湿气体在第一风道210内流经蒸发器340时，高湿气体内的水蒸气冷凝成液态以降低气体的湿度，实现气体的干燥除湿，此时气体的温度随之降低，高湿气体变为干燥的冷空气。另一部分高湿气体则可以直接流经第二风道220，在与第一风道210内处理后的干冷气体汇合后，混合气体流经风冷冷凝器330加热升温，再通过进风口101流回内胆100，以便于对内胆100内的餐具进行烘干处理。
由此，通过设置第一风道210和第二风道220，可以对内胆100流出的高湿气体的湿度和温度进行调节，使流回内胆100的气体具有合适的温度范围和湿度范围，便于气体顺畅地对内胆100内的餐具进行烘干，提高洗涤电器1的烘干效果。同时，不仅可以避免对内胆100流出的全部高湿气体进行干燥降温而增加洗涤电器1不必要的功耗，而且在烘干餐具的过程中，可以保证气体在风道组件200与内胆100之间进行内循环，防止外界环境中的灰尘等杂质进入内胆100而污染内胆100以及内胆100内的餐具，提高餐具的烘干安全性和可靠性。
也就是说，内胆100流出的气体一部分经过蒸发器340，另一部分未经过蒸发器340，两部分的气体在风冷冷凝器330前混合，再经过进风口101进入内胆100，控制了流经 蒸发器340的部分气体总量，便于控制流回内胆100的气体的湿度和温度，提高气体的单位除湿能力。
因此，根据本申请实施例的洗涤电器1具有对餐具的烘干效果好、烘干过程安全可靠和能耗低等优点。
下面参考附图描述根据本申请具体实施例的洗涤电器1。
在本申请的一些具体实施例中，如图1-图5所示，根据本申请实施例的洗涤电器1包括内胆100、风道组件200和热泵系统300。
具体地，如图3所示，第一风道210包括主风道211、流入段212和流出段213，主风道211的两端分别与流入段212和流出段213连通。其中，第二风道220的出口与流出段213连通，风冷冷凝器330的至少一部分设在流出段213内。这样不仅便于第一风道210通过进口和出口与内胆100连通为循环回路，而且便于第一风道210内的气体与第二风道220内的气体汇合后再流经风冷冷凝器330进行加热升温。
具体而言，第一风道210包括主风道211、流入段212和流出段213，主风道211的两端分别与流入段212和流出段213连通，第一风道210的进口形成在流入段212上，流入段212通过第一风道210的进口与出风口102连通。第一风道210的出口形成在流出段213上，流出段213通过第一风道210的出口与进风口101连通。蒸发器340设在主风道211或流出段213内。第二风道220的进口与第一风道210连通，第二风道220的出口与流出段213连通，风冷冷凝器330的至少一部分设在流出段213内，在气体的流动方向上，第二风道220与流出段213的连接处位于风冷冷凝器330的上游，第二风道220与流出段213的连接处位于蒸发器340的下游。换言之，第一风道210内的气体在流经蒸发器340后再流经风冷冷凝器330，然后流回内胆100，第二风道220内的气体在流经风冷冷凝器330后再流回内胆100。
在一些具体实施例中，如图3所示，第二风道220的进口与流入段212连通，以使第二风道220的进口通过流入段212与出风口102连通。这样可以通过流入段212将内胆100的高湿气体导流至第一风道210的主风道211和第二风道220，便于第一风道210和第二风道220与内胆100连通为循环回路。
在另一些具体实施例中，流入段212、第二风道220的进口分别与出风口102直接连通。这样内胆100内的高湿气体可以分别单独流入第一风道210和第二风道220内，避免第一风道210和第二风道220内的气体相互干涉而影响气体的正常流动。
可选地，主风道211的流通面积大于第二风道220的流通面积。这样可以保证从内胆100流出的高湿气体中的大部分可以经过蒸发器340进行干燥除湿处理，便于降低气体的湿度，提高气体对餐具的烘干效果。
在一些实施例中，如图3所示，风道组件200包括第一通风口230和第二通风口240，第一通风口230和第二通风口240分别与外界连通。其中，洗涤电器1还包括第一切换件410和第二切换件420，第一切换件410用于控制主风道211与第一通风口230或流入段212的通断，第二切换件420用于控制主风道211与第二通风口240或流出段213的通断。这样第一风道210的主风道211根据需要可以分别与外界环境或内胆100连通为循环回路，便于提高第一风道210内流通气体的灵活变化，提高风道组件200的功能性和适用性。
可选地，第一通风口230和第二通风口240可设置在洗涤电器1的侧板、踢脚板或外壳等不被橱柜或外物遮挡的位置。进风口101和出风口102可设置在内胆100的侧壁面或顶面等便于与内胆100相通的位置。
具体地，如图3所示，洗涤电器1还包括洗涤系统500，热泵系统300还包括水冷冷凝器350，水冷冷凝器350用于加热洗涤系统500内的洗涤液。洗涤电器1具有烘干状态和加热状态，在洗涤电器1处于烘干状态下，第一切换件410连通主风道211与流入段212且关闭第一通风口230，第二切换件420连通主风道211与流出段213且关闭第二通风口240。在洗涤电器1处于加热状态下，第一切换件410连通主风道211与第一通风口230且隔断主风道211与流入段212，第二切换件420连通主风道211与第二通风口240且隔断主风道211与流出段213。这样洗涤电器1处于烘干状态下，风道组件200可以与内胆100形成内循环，便于蒸发器340对内胆100流出的高湿气体进行干燥除湿处理，不仅可以提高洗涤电器1的烘干效果，而且可以避免外界环境中的灰尘等进入内胆100而对内胆100和餐具造成污染。洗涤电器1处于加热状态下，风道组件200可以与外界环境连通，便于蒸发器340对外界环境中空气的热量进行收集，提高热泵系统300的加热效率，提高洗涤电器1的洗涤效果。
举例而言，蒸发器340设在主风道211内，当洗涤电器1处于加热状态下，需要对洗涤液进行加热时，可以通过第一切换件410和第二切换件420使主风道211的两端分别通过第一通风口230和第二通风口240与外界环境连通，这样外界环境中的空气可以不断地流经蒸发器340，便于蒸发器340更好地吸收外界环境中空气的热量。当洗涤电器1处于烘干状态下，需要对内胆100内的餐具进行烘干时，可以通过第一切换件410和第二切换件420使主风道211的两端分别与流入段212和流出段213连通，使风道组件200与内胆100之间形成循环的内回路，可以利用蒸发器340对内胆100流出的高湿气体进行干燥除湿处理，以便于处理后的气体可以流回内胆100对餐具进行烘干处理。
可选地，如图3所示，洗涤电器1还包括洗涤系统500，热泵系统300包括水冷冷 凝器350，水冷冷凝器350用于加热洗涤系统500内的洗涤液。这样可以利用水冷冷凝器350加热洗涤系统500内的洗涤液，高温洗涤液将餐具上的污染物冲走并将热量带到餐具上，从而洗涤电器1可以在较短的洗涤时间内获得较高的洗净率和干燥率。
在一些具体实施例中，如图2所示，压缩机310、节流装置320、风冷冷凝器330、水冷冷凝器350和蒸发器340串联设置，在热泵系统300内换热介质的流动方向上，水冷冷凝器350位于风冷冷凝器330的上游。这样吸收热量后的换热介质先流经水冷冷凝器350再流经风冷冷凝器330，可以保证热泵系统300通过水冷冷凝器350优先对洗涤系统500内的洗涤液进行加热，从而保证洗涤电器1的洗涤效果。
这里需要理解的是，“在热泵系统300内换热介质的流动方向上，水冷冷凝器350位于风冷冷凝器330的上游”是指通过蒸发器340吸收热量后的换热介质先流经水冷冷凝器350，再流经风冷冷凝器330。
具体而言，蒸发器340、压缩机310、水冷冷凝器350、风冷冷凝器330和节流装置320顺次串联为循环回路。节流装置320可以为膨胀阀，进一步地节流装置320可以为电子膨胀阀。
在另一些具体实施例中，如图3所示，热泵系统300包括第一支路361、第二支路362和第三支路363，第二支路362和第三支路363的两端分别与第一支路361连通。其中，压缩机310、蒸发器340和节流装置320连接在第一支路361，水冷冷凝器350和第一通断阀323连接在第二支路362，风冷冷凝器330和第二通断阀324连接在第三支路363。这样在热泵系统300加热洗涤液时，可以连通第一通断阀323且断开第二通断阀324，此时第三支路363内没有换热介质流动，可以降低热泵系统300的管路流动阻力，降低加热洗涤液时热泵系统300的能耗。在干燥或保管餐具的阶段，可以连通第二通断阀324且断开第一通断阀323，此时第二支路362内没有换热介质流动，可以降低热泵系统300的管路流动阻力，降低干燥和保管餐具阶段热泵系统300的能耗。由此，便于提高洗涤电器1的能效，降低能耗。
在另一些具体实施例中，如图4所示，节流装置320包括第一膨胀阀321和第二膨胀阀322，热泵系统300包括第一支路361、第二支路362和第三支路363，第二支路362和第三支路363的两端分别与第一支路361连通。其中，压缩机310和蒸发器340连接在第一支路361，水冷冷凝器350和第一膨胀阀321连接在第二支路362，风冷冷凝器330和第二膨胀阀322连接在第三支路363。这样利用第一膨胀阀321和第二膨胀阀322可以构成双节流装置320系统。在热泵系统300加热洗涤液时，第一膨胀阀321进入正常工作状态，第二膨胀阀322关死或者开度处于最小状态，此时第三支路363内没有换热介质流动，降低热泵系统300管路流动阻力，降低加热洗涤液时热泵系统 300的能耗。在干燥或者保管餐具阶段，第二膨胀阀322进入正常工作状态，第一膨胀阀321关死或者开度处于最小状态，此时第二支路362内没有换热介质流动，降低热泵系统300的管路流动阻力，降低干燥和保管阶段时热泵系统300的能耗。由此，便于提升洗涤电器1的能效，降低能耗。
具体地，如图1所示，洗涤系统500包括喷臂组件510、集水件520和洗涤泵530，喷臂组件510设在内胆100内，集水件520设在内胆100且位于喷臂组件510的下方(内胆100的上下方向如图1所示)，洗涤泵530分别与喷臂组件510和集水件520连通。这样可以利用洗涤泵530将洗涤系统500内的洗涤液输送到喷臂组件510，利用喷臂组件510对餐具进行不断的覆盖喷射洗涤，达到清洁餐具的目的。集水件520可以对内胆100内的洗涤液进行收集，以实现洗涤液在洗涤系统500内的循环流动。
这里需要理解的是，图1中的上下方向仅为了便于表述内胆100内结构的上下位置关系，并非对于洗涤电器1实际结构的限定。
更为具体地，如图3所示，喷臂组件510包括顶喷臂511、中喷臂512和下喷臂513，集水件520形成为位于内胆100下部的水杯集水槽。
可选地，如图3所示，第一风道210内设有第一风机600，在气体的流动方向上第一风机600位于蒸发器340的上游。这样在第一风机600的作用下，便于气体顺畅地流经蒸发器340，提高风道组件200内的通风量，提高热泵系统300的换热效率。
进一步地，第一风机600设在第一风道210的主风道211内。
可选地，如图3所示，内胆100设有与外界环境连通的第三通风口103，第三通风口103位于内胆100的顶端。第三通风口103处设有可移动的密封件，当内胆100的内部压力大于预设压力时，密封件会被顶开，实现第三通风口103的打开，此时第三通风口103与内胆100连通，内胆100内的气体可以通过第三通风口103排出到外界环境中。当内胆100的内部压力小于或等于预设压力肘，密封件对第三通风口103进行密封，以便在内胆100内形成密封空间。
在一些实施例中，当洗涤电器1处于对洗涤液进行加热的状态时，热泵系统300内压缩机310工作，将高温高压的换热介质泵送至水冷冷凝器350，以对洗涤系统500内的洗涤液进行加热，换热介质与洗涤液完成换热后流出水冷冷凝器350，再流入风冷冷凝器330，然后经过节流装置320进行节流后，换热介质变成低温低压的换热介质再流入蒸发器340，换热介质在蒸发器340内与气体进行换热，然后换热介质流回压缩机310完成整个热泵系统300的加热循环。
在此模式下，洗涤泵530工作，将洗涤液从集水件520泵送到热泵系统300内的水冷冷凝器350进行加热后，然后供送到喷臂组件510对餐具进行洗涤。
在此模式下，第一风机600启动，第一切换件410连通主风道211与第一通风口230，第二切换件420连通主风道211与第二通风口240。外界环境中的空气在第一风机600的作用下，从第一通风口230流入主风道211，流经蒸发器340后再从第二通风口240排出。
在另一些实施例中，当洗涤电器1处于对餐具进行干燥的烘干状态时，第一风机600启动，热泵系统300内压缩机310亦处于启动状态。在此模式下，压缩机310将高温高压的换热介质泵送至水冷冷凝器350，以对水冷冷凝器350和洗涤系统500内部件进行烘干，然后流入风冷冷凝器330对内胆100内气体进行循环加热，从而实现加快对餐具上的水滴蒸发干燥和提升餐具本身的温度。
进一步地，经过风冷冷凝器330冷凝后的换热介质经过节流装置320节流后，流入风冷蒸发器340。内胆100高湿气体在第一风机600的作用下从出风口102流入风道组件200，部分经过风冷蒸发器340进行降温除湿，与另一部分未经蒸发器340的气体混合后流向风冷冷凝器330，然后通过进风口101进入内胆100，与高温高湿的内胆100气体混合或将高温高湿的气体从出风口102挤出，如此循环，实现对内胆100内气体进行降湿的效果，从而提高干燥效率，缩短干燥时间。
