通常，在洗碗机200清洗餐具完成之后会朝向洗涤腔2101内通入热空气，以对餐具进行干燥。在本发明的一些实施例中，进入风道件2内的空气可以经由加热装置3加热后通入洗涤腔2101内对洗涤腔2101内的餐具进行干燥。
可以理解的是，加热风道11内的热风进入洗涤腔2101后能够对洗涤腔2101内的餐具进行干燥，提高用户使用满意度。
另外，洗碗机200工作过程时，洗涤腔2101内会产生大量的高温高湿的气体，这样的气流如果直接排放至洗涤腔2101的外部会导致洗碗机200在工作工程中不断的排放高温高湿的气体，这样会极大地降低客户体验度，因此，通过在本体1内设置所述冷凝风道，使得洗涤腔2101内排出的高温高湿的气流可以经过冷凝后再进一步排出。
内胆2101内部的高湿空气经过所述冷凝风道冷凝后的空气可以直接排到箱体外部(称为外循环)，或者这部分的空气还可以与加热风道11的入口(例如加热进风口111)连通，加热后再输送回到内胆2101里(称为内循环)。
例如，所述冷凝风道可以位于风道件2的上游，所述冷凝风道处设有换热器。可以理解的是，加热装置3可对经过所述换热器换热的气流进行加热，使得由加热出风口112进入洗涤腔2101内部的气流具有较高的温度，从而提高洗涤腔2101内部餐具的干燥效率。
据本发明实施例的用于洗碗机的干燥装置100，通过加热装置3可以将进入风道件2内的空气进行加热，便于通过热空气对洗涤腔2101内的餐具等进行干燥，有利于提高客户满意度。
相关技术的洗碗机中，在洗完餐具后需要对洗涤腔内的餐具进行烘干，因此干燥装置中具有加热件，然而，加热件直接放置在干燥装置的加热风道内不仅容易导致加热件损坏，还使得加热风道受热不均导致加热风道损坏。
为了解决上述技术问题，在一些实施例中，风道件2的至少部分可以形成为双层结构，风道件2包括第一层壳体21和第二层壳体22，第二层壳体22可以设在第一层壳体21外。由此，通过将风道件2的至少部分设置为双层结构，有利于减小热量的传递，降低风道件2外侧的温度。
其中，第二层壳体22的至少部分可以形成为双层结构，由此，双层结构之间的空气层可以降低导热系数，降低风道件2外侧的温度，还可以提高风道件2的结构强度。
在一些实施例中，第一层壳体21可以为金属件，第二层壳体22的至少部分可以为阻燃塑料件。这样不仅便于热量的传递，还有利于提高风道件2的使用可靠性。
另外，由于所述冷凝风道的材料的耐热不高，通过将风道件2的至少部分设置为双层结构，还有利于保护所述冷凝风道，防止所述冷凝风道受到高温影响而损坏。
此外，当干燥装置100应用于洗碗机200上时，有利于减小干燥装置100传递至洗碗机 200的箱体的热量，从而能够防止所述箱体的温度过高，进而降低烫伤用户的风险。
例如，风道件2的高温处可以形成为双层结构。具体地，加热风道11中由于热通量(热流密度)最高的地方出现在相对于热风阻挡作用最大的区域，即风道拐弯处，所以加热风道11的高温处往往出现在加热风道11的拐弯处，如图3所示的区域P。通过在高温处设计双层结构，可有效降低此处风道件2外侧壁的温度，同时还能起到加强结构强度的作用，从而能够有效解决加热风道11外部局部温度较高的问题，提高干燥装置100的安全性。
当然，在一些实施例中，也可以将风道件2的整体均设置为双层结构；还可以在风道件2与加热装置3之间设有隔热件等；在一些实施例中，通过双层结构的风道件2与隔热件的配合，可以进一步降低烫伤用户的风险。
根据本发明实施例的用于洗碗机的干燥装置100，通过将风道件2的至少部分设置为双层结构，中间的空气层可以降低导热系数，从而有利于减小热量的传递，降低风道件2外侧的温度，进而降低烫伤用户的风险。
在一些实施例中，参照图4，风道件2上还可以设有向外凸出的散热凸筋27。例如，风道件2上还可以设有散热凸筋27，散热凸筋27可以向外凸出的风道件2的外表面。当干燥装置100应用于洗碗机200上时，通过散热凸筋27可以进行散热，并且使得风道件2的外表面与洗碗机200的箱体的内壁面之间形成一个空隙，相较于风道件2的外表面直接与洗碗机200的箱体接触而言，有利于减小传递至所述箱体的热量，从而能够防止所述箱体的温度过高，进而降低烫伤用户的风险。
其中，散热凸筋27可以设在风道件2与所述箱体接触的一侧的外壁面，散热凸筋27可以包括多个，并且多个散热凸筋27可以间隔开布置。在本发明的描述中，“多个”的含义是两个或两个以上。
通过在风道件2的高温处的外侧设计向外凸出的散热凸筋27，可使该高温区域与洗碗机200的箱体的接触面积减小，有效避免所述箱体相应区域温度过高的风险，同时还能起到加强此处的结构强度的作用，有效解决加热风道11外部局部温度较高的问题，提高干燥装置100的安全性。
根据本发明实施例的用于洗碗机的干燥装置100，通过在风道件2的外侧设置散热凸筋27，可以使风道件2的外表面与洗碗机200的箱体的内壁面之间形成一个空隙，相较于风道件2的外表面直接与洗碗机200的箱体接触而言，有利于减小传递至所述箱体的热量，从而能够防止所述箱体的温度过高，降低用户发生烫伤的风险。
在一些实施例中，用于洗碗机的干燥装置100还可以包括温控器6，温控器6和加热装置3均与洗碗机200的控制器电连接，通过温控器6可以对加热装置3的温度进行 检测，由此，可以在温控器6感应到的温度值高于预设温度值时通过所述控制器控制加热装置3断电，从而有利于提高洗碗机200的使用安全性。
具体地，加热装置3在工作不正常时或其他不正常情况(进风机停转)等，加热装置3由于得不到及时散热导致温度上升，通过安装温控器6，当温控器6感应的温度值高于设定动作温度(可按需设置)时，温控器6会切断加热装置3的供电，从而保证干燥装置100的使用安全性。温控器6的安装方式、安装位置直接影响温控器6的反应精度，从而影响干燥装置100的安全性，进而影响洗碗机200的安全性。
如图3和图7所示，通过将温控器6装配在紧挨着加热装置3的位置，能够有效提高温控器6的感应精度，从而有利于提高干燥装置100的安全性。
根据本发明实施例的用于洗碗机的干燥装置100，通过温控器6可以对加热装置3的温度进行检测，从而可以在温控器6感应到的温度值高于预设温度值时通过所述控制器控制加热装置3断电，有利于提高洗碗机200的使用安全性。
结合图4，在加热装置3外设计双层保护(第一层壳体21和第二层壳体22)，第一层壳体21具有固定和保护加热装置3的作用(优选金属材质)，第二层壳体22具有固定和保护加热装置3及温控器6的作用，通过在第二层壳体22的外侧壁上设置向外凸出的散热凸筋27，使得干燥装置100可以通过散热凸筋27与洗碗机200的箱体接触，这样可以减小接触面积，有利于降低所述箱体的温度，降低烫伤用户的风险。
另外，第二层壳体22局部(例如，第二层壳体22对应设置加热装置3处)可以采用格栅式结构，由此，既可以节省材料，还能够使第一层壳体21的表面热量及时散掉，不至于过高，使用安全性好。第二层壳体22局部也可以设置为双层结构，例如，可以将图3中的圈示P处设置为双层结构，双层结构间隔开形成间隙，由此，通过双层结构之间的空气层可以降低导热系数，减小热量的传递，还有利于提高第二层壳体22的结构强度。
加热风道11由于要保证干燥装置100的安全性，采用如图2所示的结构，可解决既保证干燥装置100在一定温度运行时的安全特性，同时亦具有简便的安装特性，其中，加热风道11包括三部分(安装段23、倾斜段24以及过渡段25)。
其中，第一部分(例如安装段23)为用来固定保护加热装置3的第一层壳体21，第一层壳体21可以采用具有一定防腐特性的金属材质，如镀锌板等。
第二部分(例如过渡段25)为具有固定和保护加热装置3及温控器6的第二层壳体22，同时为加热风道11转弯区域(此处为风道高温区，加热风道11中由于热通量最高的地方出现在相对于热风阻挡作用最大的区域，即风道拐弯处，参照图3中的圈示P处)，此处可以采用同第一层壳体21一样的材质，为节省材质，此处可以选用阻燃特性好的 塑料，如PBT(阻燃等级VO)。其中，PBT为聚对苯二甲酸丁二醇酯，又名聚对苯二甲酸四次甲基酯，英文名polybutylene terephthalate，属于聚酯系列。
第三部分(例如倾斜段24)为温度较低区域，此处由于要和内胆210进行装配，结构相对于前两部分较为复杂，采用PP+GF(GF含量可以为20％-40％；优选地，GF含量为30％)的材料。
聚丙烯，英文名称：Polypropylene(PP)，是由丙烯聚合而制得的一种热塑性树脂。GF是glass fiber的首字母，glass fiber中文名是玻璃纤维，简称玻纤。PP是聚丙烯塑料，GF+PP指的是加玻纤的聚丙烯材料。纯的PP材料刚性，强度及耐热性比较差，加入玻纤后可以改善这些不足。PP材料通常用于普通日用塑料制品，而GF+PP材料则应用于家电产品，汽车配件，五金工具等制品。
例如，PP+20％GF具有高流动,30％GF的加入使其具有高刚性,尺寸稳定,是结构件,散热风扇,耐压壳体的理想材料。
由此，根据功能及不同部分的特性将加热风道11分成三大部分，分别采用不同材料，可有效地解决加热风道11的安全特性，同时能够具有更好的加工特性，降低成本。
在一些实施例中，用于洗碗机的干燥装置100还可以包括温控器6，温控器6和加热装置3均与洗碗机200的控制器电连接，并且温控器6与风道件2可拆卸连接。由此，便于实现温控器6在风道件2上的安装和拆卸。
具体地，加热装置3在工作不正常时或其他不正常情况(进风机停转)等，加热装置3由于得不到及时散热导致温度上升，通过安装温控器6，并使温控器6与风道件2可拆卸连接，当温控器6感应的温度值高于设定动作温度时，温控器6会切断加热装置3的供电，从而保证干燥装置100的使用安全性。
根据本发明的一些实施例，本体1内可以设有多个限位块，风道件2可以卡接在多个限位块限定出的限位槽中。由此，通过限位块与限位槽的配合，易于实现风道件2在本体1内的安装和拆卸。
本发明对所述限位块和所述限位槽的具体结构不作限定，具体设置以所述限位块和所述限位槽相匹配且实现风道件2在本体1内的可靠安装为宜。
结合图1和图2，根据本发明的一些实施例，风道件2的一端连接有干燥风机4且另一端与加热出风口112相连，在加热风道11的气流流动方向上，加热装置3位于干燥风机4的下游。可以理解的是，干燥风机4能够使得加热风道11内的气流加速流通，从而有利于提高洗碗机200的干燥效率。
可以理解的是，加热装置3能够对干燥风机4输出的气流进行加热，使得进入洗涤腔2101内部的气流具有较高的温度，从而有利于提高洗涤腔2101内部餐具的干燥效率。
需要说明的是，如果将加热装置3设在干燥风机4的上游，也就是说，经过加热的气流在干燥风机4的带动下流向加热出风口112，这样当经过加热的气流与干燥风机4的风机壳和叶轮接触时会产生一定的温降，这样不利于提高干燥装置100的干燥效果。
此外，在一些实施例中，加热装置3与风道件2可拆卸连接。由此，通过将加热装置3可拆卸地安装在风道件2上有利于加热装置3的更换、检修及保护。
进一步地，参照图2，加热风道11在邻近加热出风口112处形成为在加热风道11内的气流流动方向上朝下倾斜的通道，以防止洗涤腔2101内的洗涤水倒流入加热风道11。
可以理解的是，由于加热出风口112直接与洗涤腔2101相连，因此，洗涤腔2101内的水位过高时有可能出现倒流进入加热风道11的现象。
为此，在本发明的干燥装置100中，由于加热风道11在邻近加热出风口112处形成为在加热风道11内的气流流动方向上朝向下倾斜的通道。例如，当洗涤腔2101的水进入加热风道11后，由于加热风道11在邻近加热出风口112处的倾斜角度原因，洗涤腔2101的水会回流至洗涤腔2101中，从而避免了加热出风口112处积水的现象发生。
根据本发明实施例的用于洗碗机的干燥装置100，由于加热风道11邻近加热出风口112处形成为在加热风道11内的气流流动方向上朝向下倾斜的通道，实现了由加热出风口112进入洗涤腔2101内的洗涤水回流至洗涤腔2101的功能，避免了加热风道11内积水的现象发生，从而可以保证加热风道11内的气流流量，进而可以在一定程度上提高干燥装置100的干燥效率。
参照图4，根据本发明的一些实施例，第一层壳体21包括两个第一子壳体211，两个第一子壳体211中的其中一个上形成有第一卡扣部2111，且两个第一子壳体211中的另一个上形成有第一卡槽2112，第一卡槽2112与第一卡扣部2111相匹配，第一卡扣部2111与第一卡槽2112卡接以使两个第一子壳体211扣合。
第二层壳体22包括两个第二子壳体221，两个第二子壳体221中的其中一个上形成有第二卡扣部2211，且两个第二子壳体221中的另一个上形成有第二卡槽2212，第二卡槽2212与第二卡扣部2211相匹配，第二卡扣部2211与第二卡槽2212卡接以使两个第二子壳体221扣合。
由此，通过将第一层壳体21和第二层壳体22设置为分体式结构，便于实现第一层壳体21以及第二层壳体22的组装，且有利于加热装置3的安装和拆卸，工艺性好。
可以理解是，如果直接将风道件2设计成一体形成的带通道的盒状，这样的结构不利于加热装置3安装，且生产工艺较为复杂，在外力作用下容易发生损坏。
而在本发明实施例中，风道件2为双层结构(例如，风道件2包括第一层壳体21和第二层壳体22)，第一层壳体21可以内嵌于第二层壳体22内，第一层壳体21包括两个第一 子壳体211，两个第一子壳体211扣合(例如卡接等)形成第一层壳体21；第二层壳体22包括两个第二子壳体221，两个第二子壳体221扣合(例如卡接等)形成第二层壳体22，这样既方便了加热装置3的安装，还能够防止加热装置3晃动，此外，还可在一定程度上简化风道件2的生产工艺，降低风道件2的生产成本。
当然，在本发明的其他实施例中，两个第一子壳体211(或两个第二子壳体221)还可通过螺钉、连接销钉等连接件连接。
进一步地，参照图3和图4，加热装置3包括加热体31和接线端32，接线端32与加热体31相连，风道件2上设有避让缺口26，避让缺口26可以避让接线端32，通过避让缺口26便于使接线端32伸出风道件2外，结合合理且工艺性好。
避让缺口26包括：第一避让缺口212和第二避让缺口222，第一避让缺口212可以形成在第一层壳体21上；第二避让缺口222可以形成在第二层壳体22上，并且第二避让缺口222与第一避让缺口212可以对应。
这里，需要说明的是，图4中风道件2处于分解状态，图4中示意性地标出了第一避让缺口212和第二避让缺口222的位置。
进一步地，参照图4和图7，接线端32处还套设有支撑件5，接线端32通过支撑件5设在避让缺口26处。由此，通过支撑件5可以对接线端32与风道件2相连的部分进行支撑，从而有利于保护接线端32，提高加热装置3的使用可靠性。
这里的支撑件5可以为例如绝缘件等，这样可以使接线端32与风道件2绝缘，安全性好且有利于提高干燥装置100的使用可靠性。
可选地，结合图4和图2，每个第一子壳体211均包括：第一底壁2113和第一侧壁2114，第一侧壁2114包括两个，并且两个第一侧壁2114可以在图4中所示的AB方向上相对且间隔开布置，第一侧壁2114设在第一底壁2113沿宽度方向(参照图4中所示的AB方向)上的两侧且沿第一底壁2113的长度方向(参照图2中所示的气流流动的箭头指向)延伸。
其中，两个第一侧壁2114中的其中一个上形成有适于避让接线端32的第一子避让缺口，当两个第一子壳体211扣合时，两个第一子避让缺口配合限定出第一避让缺口212。
第一卡扣部2111和第一卡槽2112均形成在第一侧壁2114上，第一卡扣部2111包括多个，并且多个第一卡扣部2111沿第一侧壁2114的长度方向间隔开，第一卡槽2112与第一卡扣部2111一一对应。由此，通过第一卡槽2112与第一卡扣部2111的配合，易于实现两个第一子壳体211之间的安装和拆卸。
进一步地，参照图4，每个第二子壳体221均包括：第二底壁2213和第二侧壁2214，第二侧壁2214包括两个，并且两个第二侧壁2214相对且间隔开布置，第二侧壁2214设在第二底壁2213沿宽度方向上的两侧且沿第二底壁2213的长度方向延伸。
其中，两个第二侧壁2214中的其中一个上形成有第二子避让缺口，所述第二子避让缺口与所述第一子避让缺口对应，当两个第二子壳体221扣合时，两个第二子避让缺口配合限定出第二避让缺口222。
第二卡扣部2211和第二卡槽2212均形成在第二侧壁2214上，第二卡扣部2211包括多个，并且多个第二卡扣部2211沿第二侧壁2214的长度方向(例如风道件2的延伸方向)间隔开，第二卡槽2212与第二卡扣部2211一一对应。由此，通过第二卡槽2212与第二卡扣部2211的配合，易于实现两个第二子壳体221之间的安装和拆卸。
这里，在垂直于风道件2的延伸方向上，第一层子壳体211和第二层子壳体221可以大致形成为U形或H形等。
在本发明的描述中，需要理解的是，术语“长度”、“宽度”等指示的方位或位置关系仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
参照图2和图3，根据本发明的一些实施例，风道件2包括：安装段23、倾斜段24以及过渡段25。
具体地，加热装置3可以配合在安装段23内。由此，通过安装段23便于实现加热装置3在风道件2内的安装。
倾斜段24的一端与加热出风口112相连，倾斜段24内设有在加热风道11内的气流流动方向上朝下倾斜的通道；过渡段25的两端分别连接在安装段23和倾斜段24之间，过渡段25形成为在气流流动方向(参照图3中的箭头指向)上外凸的弧形。
其中，至少安装段23被构造成双层结构。例如，通过将安装有加热装置3的安装段23构造成双层结构，不仅可以减小由加热装置3传递至安装段23外壁的热量，避免风道件2的外壁面温度过高导致用户烫伤，还有利于提高风道件2的结构强度，保证加热装置3的使用安全性。
可以理解的是，倾斜段24内设有在加热风道11内的气流流动方向上朝下倾斜的通道，由此，可以实现由加热出风口112进入洗涤腔2101内的洗涤水回流至洗涤腔2101的功能。过渡段25形成为在气流流动方向上外凸的弧形，能够在洗涤腔2101内的水位进一步提高的时候仍能实现由加热出风口112进入洗涤腔2101内的洗涤水回流至洗涤腔2101的功能。
有利地，倾斜段24与水平直线的夹角a满足如下关系式，30°≤a≤60°。由此，有利于流入倾斜段24的洗涤水回流至洗涤腔2101内。当然，设计人员也可以根据实际情况设计倾斜段24与水平之间夹角a的范围。
例如，倾斜段24与水平直线的夹角a可以为30°、45°或60°等。
当然，在本发明的其他实施例中，安装段23、倾斜段24和过渡段25可以根据需要设定 其形状。倾斜段24和过渡段25也可以形成为双层结构。
在一些实施例中，倾斜段24可以通过连接管与内胆2101相连。
参照图3和图4，根据本发明的一些实施例，风道件2上设有散热凸筋27，散热凸筋27可以形成在风道件2邻近洗碗机200的箱体的一侧，风道件2正对加热装置3处形成有散热格栅28。由此，通过散热凸筋27有利于减小传递至洗碗机200的箱体的热量，从而能够避免局部温度过高；通过散热格栅28可以使由加热装置3产生的热量迅速散开，从而有利于避免第一层壳体21和第二层壳体22的局部过热而损坏。
进一步，参照图4并结合图3，散热凸筋27可以形成在过渡段25的外侧壁处。由于图3中圈示P处为高温区，通过在此处设置散热凸筋27，可以减小过渡段25与洗碗机200的箱体的接触面积，从而能够避免过多的热量传递至所述箱体，由此，当用户触碰所述箱体时有利于降低烫伤用户的风险。
参照图4，散热凸筋27包括多个，并且多个散热凸筋27可以形成在第二底壁2213的外侧，且多个散热凸筋27间隔开设置。多个散热凸筋27可以形成在第二底壁2213的外壁面的任意位置，当干燥装置100应用在洗碗机200上时，风道件2可以通过散热凸筋27与洗碗机200的箱体接触，这样可以减小接触面积，避免过多的热量传递至所述箱体，由此，当用户触碰所述箱体时有利于降低烫伤用户的风险。
其中，第二层壳体22的外侧形成有散热凸筋27，第一层壳体21和第二层壳体22中的至少一个上形成有散热格栅28。由此，通过散热格栅28可以将由加热装置3产生的热量散开，通过散热凸筋27可以进一步减小传递至洗碗机200的箱体的热量，从而能够避免所述箱体的温度过高导致用户烫伤，进而提高洗碗机200的使用安全性。
例如，可以是在第一层壳体21上形成有散热格栅28，也可以是在第二层壳体22上形成有散热格栅28，还可以是在第一层壳体21和第二层壳体22中均形成有散热格栅28。优选地，散热格栅28可以形成在第一层壳体21和/或第二层壳体22正对加热装置3处。
其中，至少安装段23处形成有散热格栅28。由于安装段23处安装有加热装置3，由此，通过在安装段23处设有散热格栅28，有利于快速将热量散开，从而能够避免局部温度过高导致干燥装置100失效。
当然，在一些实施例中，倾斜段24和过渡段25处也可以形成有散热格栅28。
进一步地，安装段23可以为金属件，并且安装段23处形成有散热格栅28。由此，通过将安装段23设置为金属件，便于热量的传递，并且通过在安装段处23形成有散热格栅28，可以通过散热格栅28及时将加热装置3产生的热量散开，从而有利于避免因局部温度过热导致干燥装置100失效。
可选地，过渡段25为金属件或阻燃塑料件，倾斜段24为塑料件。采用耐热、阻燃材料 (例如PBT材料)制造风道件2，这样可以避免加热装置3设在加热风道11内导致加热风道11局部过热损坏。
进一步地，风道件2内设有支架(未示出)，加热装置3可以通过所述支架设在风道件2内。由此，通过所述支架不仅便于加热装置3在风道件2内的安装，还有利于减小传递至风道件2外侧壁的热量。
这里，本发明对所述支架的具体结构不作限定，所述支架的设置以能够实现对加热装置3的有效支撑为宜。
温控器6和加热装置3均与洗碗机200的控制器电连接，通过温控器6可以对加热装置3的温度进行检测，由此，可以在温控器6感应到的温度值高于预设温度值时通过所述控制器控制加热装置3断电，从而有利于提高洗碗机200的使用安全性。
在一些实施例中，温控器6与风道件2可拆卸连接。由此，便于实现温控器6在风道件2上的安装和拆卸。可选地，参照图4，温控器6可拆卸地设在第一层壳体21上。
温控器6的安装方式、安装位置直接影响温控器6的反应精度，从而影响干燥装置100的安全性，进而影响洗碗机200的安全。
根据本发明的一些实施例，温控器6邻近加热装置3设置。由此，通过将温控器6邻近加热装置3设置，可以通过温控器6更加准确地检测加热装置3的温度，灵敏性提高。
进一步地，参照图3和图7，温控器6可以设于加热体31背离接线端32的一侧。这样便于温控器6的安装，且有利于准确地检测加热装置3的温度，保证使用的安全性。
例如，在图3的示例中，接线端32可以设在加热体31的B侧，温控器6设于加热体31的A侧。
进一步地，参照图3，温控器6与加热体31可以在风道件2的宽度方向上正对。风道件2的宽度方向可以参照图3中所示的AB方向，其中，温控器6设于加热体31的A侧，接线端32设在加热体31的B侧，并且温控器6与接线端32可以在AB方向上正对，此时，温控器6紧贴加热体31设置，如此，可以进一步提高温控器6温度检测的灵敏性，从而有利于保证洗碗机200的使用安全性。
参照图4和图5，根据本发明的一些实施例，温控器6包括：本体部61以及安装支耳62。
具体地，安装支耳62设在本体部61端部的周缘，并且安装支耳62包括两个，温控器6可以通过安装支耳62与风道件2相连。由此，通过安装支耳62便于实现温控器6与风道件2之间的装配。
进一步地，结合图5至图8，安装支耳62上形成有通孔621，通孔621可以沿厚度方向贯穿安装支耳62，通孔621可以被构造成例如圆形、椭圆形、长圆形或多边形等。
具体地，风道件2上可以形成有预定位部29和安装部20，其中一个通孔621与预定位部29相连以将温控器6预定位至风道件2处，另一个通孔621与安装部20相匹配以使温控器6与风道件2相连。由此，通过预定位部29和安装部20易于实现温控器6与风道件2之间的装配连接。
进一步地，参照图5至图8，预定位部29为向外凸出风道件2的卡勾，所述卡勾包括：倾斜部291和水平部292，倾斜部291与风道件2相连；水平部292设在倾斜部291的自由端，水平部292可以沿平行于风道件2的长度方向(参照图5中所示的上下方向)延伸。
其中，所述卡勾与风道件2之间限定有U形开口，其中一个通孔621适于穿过水平部292并卡接在U形开口处。由此，通过所述卡勾易于实现温控器6在风道件2上的预定位。
这里，倾斜部291可以形成为弧形面，并且倾斜部291与水平部292之间可以形成有过渡圆角，工艺性好且便于装配。
上述对预定位部29的描述只是示意性的，不能理解为对本发明的限制，在一些实施例中，预定位部29也可以形成为其他的结构形式例如锥形的定位柱等。
在一些实施例中，参照图5和图7，安装部20为安装孔，所述安装孔可以沿厚度方向贯穿风道件2，紧固件7适于穿过另一个通孔621和所述安装孔以使温控器6与风道件2相连。由此，通过所述卡勾和所述安装孔易于实现温控器6与风道件2之间的装配。
本发明不限于此，在一些实施例中，参照图9，安装部20还可以为卡接部，所述卡接部与通孔621相匹配，另一个通孔621适于与所述卡接部卡接以使温控器6与风道件2相连。由此，通过所述卡勾和所述卡接部易于实现温控器6与风道件2之间的装配。
进一步地，结合图9，在温控器6与风道件2的装配方向上，所述卡接部被构造成径向尺寸逐渐增大的锥形。例如，在图9中所示的FE方向上，所述卡接部被构造成径向尺寸逐渐增大的锥形。在温控器6与风道件2的装配方向(例如，图9中所示的FE方向)上，通孔621易于与所述卡接部卡接；在温控器6与风道件2的拆卸方向(例如，图9中所示的EF方向)上，所述卡接部限位在通孔621内，由此，便于实现温控器6与风道件2之间的可靠装配。
在一些实施例中，通过采用如图5和图7所示的安装方式，能够保证温控器6与加热装置3的相对位置。同时采用对温控器6安装固定时，先预装配，例如通过U形槽状倒扣固定，再通过一个安装部20(例如紧固件7或卡接件)装配固定，将第一层壳体21和加热装置3固定。
当温控器6通过紧固件7进行固定时，只使用一个紧固件7即可将温控器6稳定的固定在指定位置。可减少使用两个紧固件装配时对于零件精度的要求，降低生产及装配成本。
根据本发明实施例的用于洗碗机的干燥装置100，温控器6先预定位再固定连接，具有 装配操作简单，对零件精度要求低，固定效果好的特点。这种先预定位再固定连接的方式有利于保证温控器6的感应精度，提高干燥装置100安全性。
参照图1，根据本发明第二方面实施例的洗碗机200，包括：箱体(未示出)、内胆210以及干燥装置。
具体地，内胆210设在所述箱体内，内胆210内限定出洗涤腔2101；所述干燥装置设在内胆210的外侧壁处，所述干燥装置为上述的用于洗碗机的干燥装置100。由此，通过在洗碗机200上设置上述第一方面实施例的用于洗碗机的干燥装置100，可以更好地对洗碗机200进行干燥，从而有利于提高洗碗机200的卫生水平。
根据本发明实施例的洗碗机200的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
