请参图1至图10，本发明实施方式的加热器10用于洗碗机100。加热器10包括壳体11和加热部12。
加热部12包括呈管状的加热元件121。加热元件121位于壳体11内。壳体11内凸设有至少一个支架13。至少一个支架13支撑加热元件121。支架13形成有凹槽131。加热元件121穿设凹槽131以使得加热元件121的部分固定在凹槽131内以与壳体11隔开。
上述加热器10中，由于加热元件121由壳体11内的支架13支撑，并且加热元件121与壳体11隔开，这样可减少加热元件121与壳体11的接触面积，进而减少加热元件121向壳体11和外部客体的热传递，避免用户在使用洗碗机100时烫伤。
在某些实施方式中，壳体11包括相对的第一内表面111和第二内表面112。第一内表面111和第二内表面112中的至少一个内表面设置有至少一个支架13。
如此，支架13的形成较为简单。
在某些实施方式中，壳体11可由第一壳15和第二壳16连接而成，如此，加热部12的安装较为方便。第一壳15和第二壳16可通过螺钉、卡扣或焊接的方式进行连接。第一壳15和第二壳16可对加热部12进行夹持。
具体地，在图2、图3和图5所示的示例中，第一内表面111为第一壳15的内表面，第二内表面112为第二壳16的内表面，第一内表面111与第二内表面112相对。
第一内表面111和第二内表面112中的至少一个内表面设置有至少一个支架13，是指，一种情况是，加热部12可为单面支撑，即，第一内表面111设置有至少一个支架13，或第二内表面112设置有至少一个支架13；另一种情况下，加热部12可为双面支撑，即第一内表面111和第二内表面112均设置有至少一个支架13。在图1、图2和图3所示的实施方式中，加热部12为双面支撑。
在某些实施方式中，支架13由钢材料构成。如此，支架13的结构强度较大，这样可充分保证加热元件121安装在支架13上的稳定性。
请参阅图8至图10，在某些实施方式中，支架13包括支架本体132及连接在支架本体132的一侧的连接板133。支架本体132凸设在壳体11的内表面上。连接板133自支架本体132的端侧向壳体11的长度方向x延伸。连接板133开设有凹槽131。凹槽 131与壳体11的内表面隔开。
如此，加热元件121为悬置在壳体11内，这样加热元件121与壳体11之间留有充分的间隙，从而可进一步减少加热元件121向壳体11和外部客体的热传递。
在某些实施方式中，支架本体132为中空结构。
如此，这样可减少支架本体132与壳体11的接触面积，由于空气的热传递效率低，从而可减少加热元件121通过支架本体132向壳体11和外部客体的热传递。另外，中空结构的支架本体132的结构简单。
在某些实施方式中，支架本体132上开设有间隔设置的多个安装孔1321。如此，支架本体132可通过紧固件(例如螺钉)穿设安装孔而安装在壳体11上，这样可通过较简单的固定方式实现对支架13的固定。
在某些实施方式中，支架本体132呈矩形体状，凹槽131呈U形状。如此，加热元件121的部分能够较稳定地固定在凹槽131内。
在某些实施方式中，至少一个支架13包括第一支架13a。第一支架13a形成有第一凹槽131a。加热元件121包括呈弯曲状的第一连接部122及呈直线型的两个第二连接部123。第一连接部122连接两个第二连接部123。两个第二连接部123相互隔开。第一连接部122的部分固定在第一凹槽131a内。
如此，这样能够提高加热元件121固定在第一凹槽131a上的稳定性，并且不会影响加热元件121在壳体11内的安装。
具体地，请参图1，两个第二连接部123平行。两个第二连接部123位于第一连接部122的两侧。每个第二连接部123沿壳体11的长度方向x延伸。如此，两个第二连接部123相互充分隔开，这样利于加热元件121的散热。其中，当气流进入壳体11后，气流在风道110内沿壳体11的长度方向x流动。
在某些实施方式中，至少一个支架13包括与第一支架13a间隔设置的第二支架13b。第二支架13b形成有第二凹槽131b。加热元件121包括呈弯曲状的第三连接部124及第四连接部125。第四连接部125连接第三连接部124及两个第二连接部123中的一个第二连接部123。第三连接部124的部分固定在第二凹槽131b内。第一连接部122和第三连接部124分别位于第四连接部125的两侧。
如此，加热元件121具有较大的加热面积，而第一支架13a和第二支架13b的设置能够保证加热元件121设置在壳体11内的稳定性。
具体地，请参图1和图4，第一支架13a与第二支架13b相互平行。第一支架13a与第二支架13b沿壳体11的宽度方向y分布。如此，第一支架13a与第二支架13b相 互充分隔开，这样利于加热元件121的散热。
在某些实施方式中，至少一个支架13包括第三支架13c。第三支架13c与第一支架13a及第二支架13b隔开。第三支架13c形成有第三凹槽131c。第四连接部125包括呈弯曲状的第五连接部1251及呈直线型的第六连接部1252。第五连接部1251连接两个第二连接部123中的一个第二连接部123及第六连接部1252。第六连接部1252连接第三连接部124。第六连接部1252与两个第二连接部123隔开。第五连接部1251的部分固定在第三凹槽131c内。
如此，这样进一步增大了加热元件121的加热面积，而第一支架13a、第二支架13b和第三支架13c能够构成三角形的三个点，从而能够充分保证加热元件121设置在壳体11内的稳定性。
在本发明实施方式中，第一支架13a、第二支架13b和第三支架13c的结构基本相同，三个支架的结构均如图8至图10所示。
在图1所示的例子中，加热部12包括间隔设置的用于接电的两个接头120。加热元件121还包括呈直线型的第七连接部126和第八连接部127。第七连接部126的一端连接第三连接部124，其另一端连接两个接头120中的一个接头120以接电。第七连接部126与两个第二连接部123平行。第八连接部127的一端连接两个接头120中的另一接头120以接电，其另一端连接两个第二连接部123中的另一个第二连接部123。
在某些实施方式中，壳体11包括相对的第一内表面111和第二内表面112。壳体11包括连接的第一壳15和第二壳16。第一壳15形成有第一内表面111。第二壳16形成有第二内表面112。第一支架13a和第二支架13b设置在第一内表面111上。第三支架13c设置在第二内表面112上。第一凹槽131a与第一内表面111和第二内表面112隔开。第二凹槽131b与第一内表面111和第二内表面112隔开。第三凹槽131c与第一内表面111和第二内表面112隔开。
如此，加热部12为双面支撑。再有，三个支架的形成方式较为简单，并且便于加热元件121的固定。再有，第一支架13a、第二支架13b和第三支架13c能够构成三角形的三个点，从而能够充分保证加热元件121设置在壳体11内的稳定性。另外，由于三个凹槽均与壳体11的内表面隔开，这样使得加热元件121与壳体11之间留有充分的间隙，从而可减小热量的传递。
请参阅图1和图2，在安装加热元件121时，可先使得第一连接部122对准第一凹槽131a，并使得第三连接部124对准第二凹槽131b，然后同时使得第一连接部122的部分固定在第一凹槽131a内和使得第三连接部124的部分固定在第二凹槽131b内，从 而使得加热元件121悬置固定在第一壳15上，然后再使得第五连接部1251对准第三凹槽131c，并由此再使得第五连接部1251的部分固定在第三凹槽131c内，从而使得加热元件121同时悬置固定在第一壳15和第二壳体16之间，从而便可完成加热元件121的安装。这时只需固定第一壳15和第二壳体16，就能够保证加热元件121悬置固定的稳定性。
在某些实施方式中，加热元件121为加热管。如此，加热元件121具有较佳的加热效果。
在某些实施方式中，壳体11内形成有风道110。风道110内凸设有至少一个支架13。加热元件121位于风道110内。
如此，由于壳体11内形成有风道110，这样可快速地对进入加热器10内的气流进行加热，保证了气流的加热效率。
需要说明的是，加热元件121穿设凹槽131以使得加热元件121的部分固定在凹槽131内以与风道110的内壁隔开。
在本实施方式中，壳体11包括连接的第一壳15和第二壳16，第一壳15和第二壳16连接并形成风道110。
另外，若将加热器10安装在洗碗机100的内的30的侧板31上，并通过加热元件121进行加热时，风道110内形成的气流的温度能够达到250-300度。若不使得加热元件121与风道110的内壁充分隔开，则加热元件121向壳体11和外部客体(例如侧板31)的导出的热量能够使得内胆30的侧板31具有较高的温度，这样容易烫伤用户。但是在加热元件121与风道110的内壁充分隔开时，洗碗机100的内胆30的侧板31的温度较低，不容烫伤用户。
请参阅图11至图13，本发明实施方式的热风装置20包括进风部21、出风部22和上述任一实施方式所述的加热器10。加热器10连接进风部21和出风部22。热风装置20设有贯穿进风部21、加热器10和出风部22的气流通道23。
在本发明实施方式的热风装置20中，由于加热元件121由壳体11内的支架13支撑，并且加热元件121与壳体11隔开，这样可减少加热元件121与壳体11的接触面积，进而减少加热元件121向壳体11和外部客体的热传递，避免用户在使用洗碗机100时烫伤。
需要说明的是，热风装置20可用于洗碗机100。例如，在一些例子中，热风装置20安装在洗碗机100的内胆30的侧板31上。
在某些实施方式中，壳体11形成有风道110。气流通道23包括风道110。热风装 置20包括位于气流通道23内的气流挡板24。气流挡板24被配置成关闭和开启气流通道23。气流挡板24位于进风部21内。
具体地，请结合图11，进风部21内置有风机25。进风部21的侧面开设有进风口211。风机25靠近进风口211设置。出风部22开设有出风口221。进风口211连接洗碗机100的内胆30的出口32。出风口221连接洗碗机100内胆30的进口33。在热风装置20工作时，加热器10启动加热，风机25启动并从内胆30内吸气。内胆30内的气流可经出口32和进风口211进入热风装置20内，加热部12对进入加热器10内的气流进行加热，被加热后的气流由出风口221和进口33进入内胆30内。如此循环，这样可提升洗碗机100的干燥效率。
在本实施方式中，气流挡板24被配置成，能够依靠自身重力关闭气流通道23(如图11中实线所示的气流挡板24)和在风机25的风力驱动下开启气流通道23(如图11中虚线所示的气流挡板24)。风机25设置在进风部21内。
在图11所示的实施方式中，气流挡板24位于进风部21内。更具体地，在进风部21内的气流通道23侧壁设置有固定部26，固定部26开设有轴孔261，气流挡板24的侧边固定有转轴262，转轴262能够转动地穿设在轴孔261中，这使得气流挡板24能够地转动地设置在进风部21内(见图11)。
当热风装置20的风机25关闭时，气流挡板24能够依靠自身的重力关闭位于进风部21内的气流通道23。当热风装置20的风机25开启时，风机25转动形成的气流能够吹起气流挡板24，使气流挡板24能够开启位于进风部21内的气流通道23。这样气流挡板24开启和关闭气流通道23的方式较为简单。
请参阅图14，本发明实施方式的洗碗机100包括内胆30和上述任一实施方式所述的热风装置20。热风装置20安装在内胆30的侧板31外表面。
在本发明实施方式的洗碗机100中，由于加热元件121由壳体11内的支架13支撑，并且加热元件121与壳体11隔开，这样可减少加热元件121与壳体11的接触面积，进而减少加热元件121向壳体11和外部客体的热传递，避免用户在使用洗碗机100时烫伤。
具体地，在图14所示的示例中，热风装置20安装在内胆30的右侧板31外表面。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一 特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
