下面参考图1-图8描述根据本发明实施例的微波加热电器100。
如图1所示，根据本发明实施例的微波加热电器100，包括：内胆(图未示出)、金属烤架1和绝缘结构。
具体地，内胆的前面敞开；金属烤架1可取出地设在内胆内，当用户需要使用金属烤架1放置食物或餐盘时，可以将金属烤架1放置在内胆内，当用户不需要使用时，可以将金属烤架1取出，从而可以选择多种模式加热食物，提高微波加热电器100的适应性。绝缘结构设在金属烤架1上，且绝缘结构电隔离内胆和位于内胆内的金属烤架1。由于内胆一般也是金属材质的，当金属烤架1与内胆直接接触时，微波加热电器100产生的微波会使得金属烤架1与内胆的直接接触位置产生火花，存在极大的安全隐患。本申请通过利用绝缘结构将金属烤架1与内胆电隔离，可以有效地避免金属烤架1与内胆之间产生火花，从而提高微波加热电器100使用过程中的安全性。
根据本发明实施例的微波加热电器100，通过利用绝缘结构将金属烤架1与内胆电隔离，可以有效地避免金属烤架1与内胆之间产生火花，从而提高微波加热电器100使用过程中的安全性。

有利地，如图1和图2所示，绝缘结构可以包括多个绝缘套2，绝缘套2可以套在支架11的外表面上，且多个绝缘套2可以沿支架11的周向间隔布置。由此，可以在利用多个绝缘套2实现金属烤架1与内胆之间电隔离的前提下，简化绝缘结构的结构，减少绝缘结构的材料用量，降低成本，同时还便于绝缘结构与金属烤架1之间的安装。
优选地，如图1和图5所示，支架11可以呈矩形环状，且支架11的前侧支杆111、后侧支杆112、左侧支杆113以及右侧支杆114上均间隔布置有至少两个绝缘套2。例如，支架11的前侧支杆111、后侧支杆112、左侧支杆113以及右侧支杆114可以布置两个、三个、四个或四个以上的绝缘套2。通过在支架11的每一侧布置至少两个绝缘套2，可以保证支架11的前侧支杆111、后侧支杆112、左侧支杆113以及右侧支杆114与内胆有效地电隔离，从而进一步使得内胆与支架11电隔离，进一步提高微波加热电器100使用过程中的安全性。
有利地，参照图1和图2，位于左侧支杆113上的绝缘套2可以覆盖左侧支杆113的左侧、上侧以及下侧，位于右侧支杆114上的绝缘套2可以覆盖右侧支杆114的右侧、上侧和下侧。由此，可以保证内胆与支架11有效电隔离，使得绝缘套2的结构和设置更加合理。

进一步地，参照图1和图2，位于后侧支杆112上的绝缘套2可以覆盖后侧支杆112的后侧，用于实现后侧支杆112与内胆后侧壁之间的电隔离，位于前侧支杆111上的绝缘套2可以覆盖前侧支杆111的前侧，用于实现前侧支杆111与微波加热电器100的门体之间的电隔离，从而进一步实现支架11与内胆有效电隔离。
有利地，支架11的一部分可以压扁形成扁位结构，绝缘套2的内周面可以呈与扁位结构适配的形状，且绝缘套2套在扁位结构上。由此，可以方便绝缘套2安装在支架11上，提高绝缘套2的安装效率，同时保证绝缘套2和支架11之间连接的可靠性。
在本发明的一些实施例中，绝缘结构可以包括绝缘套2，绝缘套2可以套在金属烤架1的周缘并凸出金属烤架1的侧沿，由此，可以将金属烤架1与内胆间隔开，从而实现金属烤架1与内胆之间的电隔离。
在一些实施例中，参照图8，绝缘套2可以呈直筒形状，且绝缘套2垂直于其轴线的截面可以呈优弧形状。由此，可以增大绝缘套2覆盖的支架11的沿支架11周壁周向方向的面积，进一步提高金属烤架1与内胆之间电隔离的可靠性。
在一些实施例中，内胆的左侧壁和右侧壁上形成有沿前后方向延伸的滑轨，金属烤架1沿滑轨可滑动，绝缘结构将位于内胆内的金属烤架1与滑轨、内胆的内周面隔开。以避免金属烤架1与滑轨或内胆的内周壁之间接触，从而保证金属烤架1与内胆之间有效电隔离。
在一些实施例中，参照图1，搁置架12包括纵向杆122和横向杆121，纵向杆122沿前后方向延伸，横向杆121沿左右方向延伸，具体地，结合图1，横向杆121可以包括一个或沿前后方向间隔布置的多个，纵向杆122可以包括沿左右方向间隔布置的多个，且每个纵向杆122的一端与横向杆121相连，且另一端与横向杆121或支架11的前侧支杆111或后侧支杆112相连，且横向杆121的左端或右端中的至少一个端部水平延伸、向上倾斜延伸或向下倾斜延伸。

绝缘套2呈直筒形状，且绝缘套2垂直于轴线的截面呈优弧形状。位于左侧支杆113上的两个绝缘套2覆盖左侧支杆113的左侧、上侧以及下侧，且配合限定出位于左侧支杆113外侧的第一绝缘面，位于右侧支杆114上的两个绝缘套2覆盖右侧支杆114的右侧、上侧和下侧，且配合限定出位于右侧支杆114外侧的第二绝缘面。位于后侧支杆112上的绝缘套2覆盖后侧支杆112的后侧，位于前侧支杆111上的绝缘套2覆盖前侧支杆111的前侧。
根据本发明实施例的微波加热电器100，同在在金属烤架1的支架11上套设多个绝缘套2，可以将支架11与内胆、滑轨以及微波加热电器100的门体间隔开，实现金属烤架1与内胆之间的电隔离，从而保证微波加热电器100在微波加热过程中的安全性，有效避免金属烤架1和内胆之间产生电火花。
