 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，若本申请实施例中有涉及方向性指示（诸如上、下、左、右、前、后……），则该方向性指示仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，若本申请实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，全文中出现的“和/或”的含义，包括三个并列的方案，以“A和/或B”为例，包括A方案、或B方案、或A和B同时满足的方案。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
热泵洗碗机包括洗涤腔和安装腔，所述洗涤腔用于供待洗涤餐具放置，所述安装腔用以供电气元件安放，由于热泵洗碗机在进行工作时，通常存在能量传递，在进行能量传递中存在将所述安装腔内的空气中的水汽液化成了冷凝水的现象，当所述安装腔汇聚大量的冷凝水后会导致所述安装腔锈蚀或者影响所述电气元件的工作，存在安全隐患。
鉴于此，本申请提供一种热泵洗碗机，旨在解决现有技术中，当所述安装腔汇聚大量的冷凝水后会导致所述安装腔锈蚀或者影响所述电气元件的工作，存在安全隐患的问题。图1至图9为本申请提供的热泵洗碗机的具体实施例的结构示意图。
请参照图1至图5，本申请提供的热泵洗碗机100包括底盘1和热泵系统，所述底盘1上侧设置有聚液槽a，所述热泵系统包括蒸发器21和压缩机22，所述蒸发器21和所述压缩机22均安设于所述底盘1，且所述压缩机22对应所述聚液槽a设置。
在本申请中，由于在所述热泵系统工作时，蒸发器21持续低温，因此蒸发器21作为冷源，因为所述蒸发器21安装于所述底盘1，在进行换热过程中，所述蒸发器21的冷量将传导至所述底盘1，所述底盘1的表面温度降低，在与空气接触时产生冷凝水，所述底盘1上侧冷凝出的冷凝水可以聚集于所述聚液槽a内，且通过安装于所述聚液槽a内的压缩机22在工作过程中释放的热量蒸发掉所述聚液槽a内的冷凝水，既实现了冷凝水的汇聚，也避免冷凝水长期处于所述聚液槽a导致所述聚液槽a锈蚀和影响电气元件的工作。另外，在所述冷凝水蒸发过程中吸热，可以带走所述压缩机22的热量，实现对所述压缩机22的降温。
具体地，参照图3和图4，在本申请的实施例中，所述聚液槽a的底部设置有支撑件，所述支撑件支撑所述压缩机22，使得所述压缩机22与所述聚液槽a的底部相间隔，如此设置，避免由于所述压缩机22与所述聚液槽a的底部直接抵接，使得所述压缩机22和聚液槽a的底部的接触处存在死角，不便于清理所述压缩机22和聚液槽a的底部的接触处，且当需要维修所述压缩机22时也拆装不便，且长时间的使用，将使得所述聚液槽a的底部和所述压缩机22的底部存在锈蚀的风险。
需要说明的是，使得所述压缩机22安装于所述聚液槽a的方式有多种，例如，可以是所述压缩机22上设置有安装座，所述安装座与所述聚液槽a的底部之间通过卡扣结构，通过螺纹连接结构等实现固定连接，具体地，本申请对此不作限定。
具体地，参照图4和图5，在本实施例中，所述支撑件包括凸设于所述聚液槽a的底部的多个凸柱1121，通过多个所述凸柱1121支撑所述压缩机22，使得所述压缩机22和所述聚液槽a的底部存在间隔，且通过螺纹连接结构将所述压缩机22安装于多个所述凸柱1121，即实现了所述压缩机22的安装，且使得所述压缩机22与所述盖体112之间可拆卸连接，便于维修和清理，操作简单，且连接牢固。
需要说明的是，考虑到所述压缩机22在工作过程中存在振动，所述支撑件的材质为弹性材质，由于弹性材质的弹性形变可以抵消振动，效果好，具体地，所述支撑件的支撑材质可以是橡胶和硅胶等，具体地，本申请对此不作限定。
由于除去汇聚的冷凝水的方式为通过所述压缩机22工作产生的热量除去汇聚于所述聚液槽a内的冷凝水，因此，所述压缩机22距离所述聚液槽a的底部的距离不能太远，否则将无法完全将所述聚液槽a内的冷凝水除去，因此，限定所述压缩机22与所述聚液槽a的底部之间的间距为L1，其中，L1满足：0＜L1≤5mm，在该范围内，可以使得所述压缩机22工作产生的热量能够完全蒸发掉所述聚液槽a内的冷凝水，提高了所述热泵洗碗机100的使用寿命，且便于所述压缩机22的安装。
由于目前通过风冷吸收所述蒸发器21的冷量的过程中，存在噪音的问题，参照3和5，在本申请的实施例中，所述底盘1包括储液箱11，所述储液箱11包括开口朝上的箱体111和盖设于所述开口的盖体112，所述盖体112局部下凹以形成所述聚液槽a，所述蒸发器21安装于所述箱体111内，所述压缩机22位于所述箱体111外，其中，所述箱体111储存有换热液，使得位于所述箱体111内的蒸发器21与存储于所述箱体111的换热液采用自然流动换热，使得所述蒸发器21可将其产生的冷量传导于所述换热液，不需要采用风机或水泵等零件，使得工作过程几乎没有噪音，效果好。
且由于所述蒸发器21和所述换热液均处于所述箱体111内，使得所述热泵洗碗机100结构紧凑，减小了所述热泵洗碗机100的体积。另外，由于所述蒸发器21和所述压缩机22分别设于盖体112的两侧，蒸发器21释放的冷量首先传递于换热液中，除去换热液储存的冷量以外还会有一部分传递于储液箱11上，由于所述储液箱11的盖体112上设置有电气元件，为了避免所述盖体112上聚集的大量冷凝水四处流溢，影响电器元件的工作甚至导致安全隐患，使得所述盖体112上的冷凝水汇聚于所述聚液槽a内，通过所述压缩机22工作释放的热量除去所述聚液槽a内的冷凝水。另外，在所述冷凝水蒸发过程中吸热，可以更好地带走所述压缩机22的热量，实现对所述压缩机22的降温。由于所述储液箱设于所述底盘1，减小了所述热泵洗碗机100的高度，增加了所述热泵洗碗机100底盘1的重量，降低了所述热泵洗碗机100的重心，增大了所述热泵洗碗机100结构的稳定性。
需要说明的是，本实施例中，换热液用于吸收所述蒸发器释放的冷量，即与所述蒸发器进行换热。由于所述换热液的种类有多种，本申请中的换热液优选在常温情况（一般为10-25℃）为液体，低温情况（一般低于10℃）为固体的换热液，即所述换热液在吸收了所述蒸发器的冷量过程中会发生相变，由液体变为固体的过程吸收所述蒸发器21大量的冷量，具体地，所述换热液可以是由无机盐、水、促凝剂、稳定剂和增稠剂组成的混合物，还可以是无机盐水溶液、水等，当所述换热液为水时，可使得所述箱体111的换热液入口与供水装置相连通，以对所述箱体111内进行加水，使得所述箱体111的换热液出口接入排水泵进行排水。
进一步地，参照图4至图6，通过使得所述聚液槽a的侧壁呈倾斜设置，使得空气中水蒸气冷凝产生的冷凝水可以沿着所述侧壁流向所述聚液槽a的底部，并汇聚于所述聚液槽a的底部，便于通过所述压缩机22的热量将所述冷凝水蒸发除去。
具体地，所述箱体111内储存的换热液的初始液面不高于所述盖体112的最低处，考虑到换热液在吸收所述蒸发器21释放的冷量的过程中，会发生相变，即由液态变成固态，如此将导体积膨胀，通过使得所述换热液的初始液面不高于所述盖体112的最低处，使得所述换热液的液面与所述盖体112之间存在间隙，为相变过程中体积膨胀预留了空间，避免由于体积膨胀而导致所述箱体111发成形变。
参照图3和图5，所述储液箱11上设有溢出口113，使得所述箱体111和外界大气相连通，由于换热液相变后体积将发生变化，当体积缩小时，外部空气由溢出口113进入所述箱体111，形成内外气压平衡，当体积膨胀时，其固态向周围扩展，挤压所述箱体111，将所述箱体111内多余的空气经由溢出口113排出，同样形成内外气压平衡，避免所述储液箱11变形，所述溢出口113高于所述盖体112的最低处，也避免换热液溢出过多，影响后续使用。
具体地，参照图3和图5，在本申请的实施例中，所述溢出口113设于所述箱体111的侧壁面，如此设置，当储存于所述箱体111内的换热液溢出时，所述换热液可以直接溢出至所述热泵洗碗机100外，便于清理，避免安全隐患。
参照图2和图7，所述热泵洗碗机100还包括洗涤箱体4，所述洗涤箱体4至少部分承压于所述盖体112的上端面，如此，通过所述洗涤箱体4将盖体112与所述箱体111压紧，使得所述盖体112承载的重量均匀的分布在箱体四周，从而使得所述箱体111和所述盖体112的之间具有均匀的密封效果，当所述箱体111内存储有换热液时，可有效地防止换热液泄露。
进一步地，为了提高所述盖体112和所述箱体111的密封性，参照图5，所述盖体112的下端面和所述箱体111之间设置有密封圈3，由于所述洗涤箱体4承压于所述盖体112，使得所述密封圈3能够更好地密封所述盖体112下端面和所述箱体111之间的间隙，提高了所述盖体112和所述箱体111连接处的密封性，避免所述换热液外溢，效果好。
具体地，参照图4和图7，所述洗涤箱体4通过安装结构安装至所述盖体112的上端面，所述安装结构包括自所述盖体112朝上延伸设置的支撑部51，所述支撑部51的上端与所述洗涤箱体4相抵接，以使得所述洗涤箱体4和所述盖体112之间形成安装间隙b，通过使得所述压缩机22位于所述安装间隙b内，实现了所述压缩机22的安装，使得所述热泵洗碗机100结构紧凑。
需要说明的是，所述洗涤箱体4安装于所述盖体112上端面的发方式有多种，例如，所述洗涤箱体4和所述盖体112之间还可以设置安装凸起和与所述安装凸起相适配的安装卡槽，所述安装凸起沿所述盖体112的周缘延伸设置，如此设置，通过所述安装凸起和所述安装卡槽配合安装，并通过螺纹结构将所述安装凸起锁紧固定与所述安装卡槽内，以使得所述洗涤箱体4和所述盖体112之间形成安装间隙b，通过使得所述压缩机22位于所述安装间隙b内，实现了所述压缩机22的安装，使得所述热泵洗碗机100结构紧凑。
进一步的，参照图4和图7，所述支撑部51沿所述盖体112周缘延伸设置，如此，使得通过所述支撑部51支撑所述洗涤箱体4时，所述盖体112受到的来自所述洗涤箱体4的压力均匀地分布于所述盖体112的周缘，提高密封效果。
为了将所述洗涤箱体4固定于所述盖体112，参照图4和图7，所述安装结构还包括连接部52，所述连接部52沿上下向延伸设置，所述连接部52的一端与所述洗涤箱体4的侧壁相连接，所述连接部52的另一端与所述支撑部51相连，如此实现了所述洗涤箱体4与所述盖体112的连接固定，且结构简单且易安装。
为了避免在将所述洗涤箱体4安装至所述盖体112时发生错位，参照图7，所述洗涤箱体4和所述支撑部51之间还设置有导向结构，所述导向结构包括沿上下向延伸设置的导向部61和与所述导向部61相适配的配合部62，所述导向部61和所述配合部62中，其中一者设于所述洗涤箱体4，另一者设于所述支撑部51，通过使得所述导向部61和所述配合部62配合安装，对所述洗涤箱体4进行安装导向，使得所述洗涤箱体4能够精确地安装至所述盖体112，操作简单。
所述导向部61和所述配合部62的种类有多种，例如，所述导向部61和所述配合部62可以设置为导向槽和与所述导向槽相适配的导向凸起，具体地，在本申请的实施例中，所述导向部61设置为导向柱，所述配合部62设置为与所述导向部61相适配的导向孔，通过所述导向柱和所述导向孔配合安装，即实现了对所述洗涤箱体4的导向作用，也起到了对所述洗涤箱体4的支撑作用，使得所述洗涤箱体4安装稳定。
具体地，所述洗涤箱体4的底部设置有排水槽41，参照图1至图3，所述热泵洗碗机100还包括洗涤系统，所述洗涤系统包括设于所述安装间隙b的进水流路c，所述进水流路c的入水口c1与所述排水槽41相连通，所述进水流路c的排水口c2用于与设于所述洗涤箱体4内的喷臂7相连通，所述进水流路c上设置有循环水泵8，所述热泵系统还包括设于所述进水流路c上的冷凝器23，所述冷凝器23包括进水管路，所述进水管路具有冷凝进水口231和冷凝出水口232，且所述冷凝进水口231低于所述冷凝出水口232，且所述冷凝器23位于所述排水槽41和所述循环水泵8之间，如此，当需要通过所述喷臂7向所述洗涤箱体4喷水时，洗涤水先进入所述洗涤箱体4内，并充满排水槽41，然后，所述排水槽41的水沿着所述进水流路c依次经过所述冷凝器23和所述循环水泵8，所述洗涤水通过冷凝器23加热，然后通过循环水泵8将洗涤水泵入所述喷臂7以对处于洗涤箱体4的餐具进行洗涤，由于所述排水槽41的底部低于所述冷凝器23的冷凝进水口231，所述冷凝器23的冷凝出水口232低于所述循环水泵8的循环进水口81（参照图8），可使得所述冷凝器23中充满水，避免冷凝器23中存在空气，另外，即使所述冷凝器23内存在空气，也可以通过所述循环水泵8和所述喷臂7将气体排出，效果好。
需要说明的是，上述实施例中，通过所述循环水泵8提高驱动力，将洗涤餐具后的洗涤水重新输送至所述进水流路c上，形成一个洗涤水循环回路，实现了洗涤水的循环利用，节约了水源，且通过使得所述循环水泵8设置于所述安装间隙b内，使得所述进水流路c的结构布局紧凑，可在一定程度上减小所述热泵洗碗机100的体积。
进一步地，在洗涤完成后需要将洗涤水完全排出，所述洗涤系统还包括设于所述安装间隙b的排水流路d，所述排水流路d上设置有排水泵9，所述排水流路d的排水进口d1与所述排水槽41相连通，使得洗涤水可以在自身重力的作用下进入所述排水流路d，并使得所述排水槽41内的洗涤完成的洗涤水完全排出，排出的洗涤水流入所述排水泵9，通过排水泵9的作用，快速的将洗涤水排出，另外，由于所述排水流路d的排水进口d1低于所述冷凝器23的冷凝进水口231，使得洗涤完成后，所述冷凝器23中的洗涤水也可以回流至所述排水槽41，并通过排水流路d的排水出口d2连接的排水管排出，从而实现洗涤水完全排出，避免冷凝器23中残存有洗涤水影响下次使用。
具体地，参照图9，所述蒸发器21包括蒸发器芯管211，所述蒸发器芯管211至少部分浸没于所述换热液内，通过使得所述蒸发器芯管211排布于所述箱体111内，增大了所述蒸发器芯管211与所述换热液的接触面积，提高了换冷的效率。
进一步地，所述蒸发器芯管211设置两个，两个所述蒸发器芯管211来回弯曲设置，两个所述蒸发器芯管211一端相连通形成冷媒入口2111a，两个所述蒸发器芯管211的另一端相连通形成所述冷媒出口2111b，如此，增大了所述冷媒流动过程中与所述换热液接触的时间，提高了冷量传导效率，通过在所述蒸发器芯管211上还设置有换热翅片212，增大了所述换热液与所述蒸发器21接触面积，进一步提高了冷量的传导效率。所述热泵系统还包括冷媒循环流路24，通过使得所述冷媒出口2111b和所述冷媒入口2111a接入冷媒流路，实现了冷媒的循环。
为了缩小所述热泵洗碗机100的体积，所述蒸发器21的形状为平板状，如此设置，使得所述蒸发器21能够大部分浸没于所述换热液内，且在一定程度上可以减小所述储液箱11的体积和需要的换热液的量，减小了所述洗碗机100的高度，增加了所述洗碗机100底部的重量，降低了所述洗碗机100的重心，增大了所述洗碗机100结构的稳定性。节约了成本。
参照图1和图3，所述热泵系统还包括节流装置10，所述节流装置10设于所述安装间隙b，所述压缩机22、所述冷凝器23、所述蒸发器21及所述节流装置10均设于所述冷媒循环流路24上，热泵系统工作时，以压缩机22为驱动力促进冷媒循环流路24中的冷媒循环，处于所述压缩机22热端的所述冷凝器23加热所述进水流路c上的水，从而增加洗涤水的去污能力，所述蒸发器21向处于所述箱体111内的所述换热液传导冷量，且使得所述热泵洗碗机100结构紧凑。
考虑到当所述换热液吸收了所述蒸发器21释放的冷量后，所述换热液发生相变，由液态变成固体，当处于所述蒸发器21周围的换热液为固体时，将大大降低吸收所述蒸发器21冷量的效率，为了解决该问题，具体地，参照图1，所述热泵洗碗机100还包括加热组件101，通过使得所述加热组件101对应所述箱体111设置，利用所述加热组件101对所述箱体111进行加热，使得吸收冷量后处于固态的换热液可以吸收热量恢复为液态，便于后续热泵洗碗机100工作时，吸收所述蒸发器21的冷量。
具体地，参照图3，所述洗涤水流路还包括软水器102，通过所述软水器102去除水中钙镁离子，降低洗涤水的硬度，以达到软化硬水的目的，从而避免碳酸盐在处于所述洗涤水流路上的元件（输水管道、排水槽41及喷臂7等）产生结垢现象，大大节省成本的同时又能保证输送洗涤水的顺利进行。
以上所述仅为本申请的优选实施例，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。
