下面参考图1和图2述根据本发明实施例的烹饪器具100。
如图1和图2所示，根据本发明一个实施例的烹饪器具100包括：本体10和红外透波隔离件30，本体10包括红外加热件20，红外透波隔离件30包括相背的第一侧面31和第二侧面32，第一侧面31朝向红外加热件20设置，第二侧面32背向红外加热件20设置，第一侧面31的至少一部分与第一侧面31的另一部分不共面，即第一侧面31上具有至少两个平面不共面，至少两个平面可以相交或平行，或者第一侧面上具有弧形面。
根据本发明实施例的烹饪器具100，通过将红外透波隔离件30第一侧面31的至少两部分设置为非共面，使得红外透波隔离件30可以对红外加热件20发出的红外线进行多方向折射，使绝大部分红外线辐射到待辐射物表面，避免红外线辐射到其他位置，由此使得红外加热件20发出的红外线可以被充分利用，提高了能量利用率，提高用户的使用体验，进而提高了产品的市场竞争力。
根据本发明的一个实施例，第一侧面31上的至少一部分与第二侧面32上的至少一部分不平行，其中，这里第一侧面31上的部分与第二侧面32上的部分可以是相对布置的，即红外透波隔离件30的相背的两个外表面之间具有夹角，且第一侧面31上的至少一部分与第二侧面32上的至少一部分之间呈预设锐角布置，以对红外加热件20发出的红外线起到折射作用。
此外，这里的第一侧面31上的部分与第二侧面32上的部分也可以是非相对布置的，即第一侧面31上的一部分与第二侧面32上不与其对应的部分之间呈预设锐角布置，例如在红外透波隔离件30的延伸方向上，第一侧面31从上向下包括多段平面，第二侧面32从上向下也包括对应的多段平面，第一侧面31最上端的平面与第二侧面32最上端的平面平行布置，但第一侧面31最上端的平面与第二侧面32最下端的平面或其他非最上端的平面之间的夹角为锐角，由此使得第一侧面31和第二侧面32均为非光滑平面的结构，以便于以对红外加热件20发出的红外线进行多方向折射，使绝大部分红外线辐射到待辐射物表面，提高了红外线的利用率。
根据本发明实施例的烹饪器具100，通过将红外透波隔离件30的外表面设置有预设夹角，从而可以对红外加热件20发出的红外线进行折射，以使绝大部分的红外线辐射到待辐射物表面，避免红外线辐射到其他位置，由此使得红外加热件20发出的红外线可以被充分利用，提高了能量利用率，提高用户的使用体验，进而提高了产品的市场竞争力。
进一步地，本体10包括置物件40，红外加热件20设置在置物件40的下方，红外透波隔离件30用于将置物件40和红外加热件20间隔开，以避免置物件40上的滴落物落入红外加热件上20，而影响红外加热件20的正常使用。
根据本发明实施例的烹饪器具100，通过在置物件40和红外加热件20之间设置红外透波隔离件30，可以对红外加热件20起到保护的作用；通过将红外透波隔离件30的外表面设置有预设夹角，从而可以对红外加热件20发出的红外线进行折射，以使绝大部分的红外线辐射到置物件40上，对置物件40上的食物进行加热烹饪，避免红外线辐射到置物件40以外的位置，由此使得红外加热件20发出的红外线可以被充分利用，提高了能量利用率，提高用户的使用体验，进而提高了产品的市场竞争力。
如图1和图2所示，根据本发明的一个实施例，红外透波隔离件30沿上下方向延伸，第一侧面31形成光滑的平面，第二侧面32的至少一部分形成倾斜面33，该倾斜面33相对于光滑平面倾斜设置，从而使得第一侧面31和第二侧面32之间形成有一定的夹角，以对红外加热件20发出的红外线起到折射作用，从而可以将红外线辐射到置物件40上，且通过将第一侧面31设置为光滑的平面，使得红外透波隔离件30的结构得以简 化，从而简化了红外透波隔离件30的制造工艺和制造精度，提高了制作效率。
当然，第一侧面31也可以形成相对于红外透波隔离件30的延伸方向(如图2所示的上下方向)倾斜延伸的倾斜面33，第二侧面32也形成相对于红外透波隔离件30的延伸方向(如图2所示的上下方向)倾斜延伸的倾斜面33，第一侧面31还可以与第二侧面32沿上下方向对称布置。
如图1和图2所示，根据本发明的一个实施例，第二侧面32形成光滑平面，即背离红外加热件20的一侧为光滑平面，第一侧面31的至少一部分形成倾斜面33，倾斜面33相对于第二侧面32倾斜设置，通过将第二侧面32设置为光滑平面，使得置物件40上产生的滴落物不会残留在红外透波隔离件30上，避免红外透波隔离件30上残留污渍而影响对红外线的透射效果，进而影响烹饪器具100的烹饪效果，导致用户体验降低；而通过将靠近红外加热件20的一侧设置为倾斜面，使得红外透波隔离件30产生棱镜的效果，这样使得红外加热件20发出的红外线可以全部辐射到置物件40上，减少了辐射到其他位置造成的损耗，提高了能量利用率。
在一些示例中，置物件40沿水平方向延伸布置，红外透波隔离件30的第二侧面32沿竖直方向延伸布置，第二侧面32的延伸方向与置物件40的延伸方向垂直，即第二侧面32与水平面垂直布置，由此进一步避免置物件40上的滴落物残留在红外透波隔离件30上。进一步地，第二侧面32的延伸方向与置物件40的延伸方向之间的夹角也可以形成钝角，由此使得置物件40上的滴落物在滴落的过程中逐渐远离红外透波隔离件30，从而进一步避免了置物件40上的滴落物残留在红外透波隔离件30上。
在一些具体的示例中，红外透波隔离件30沿上下方向延伸，置物件40位于红外透波隔离件30的上方，红外加热件20位于邻近红外透波隔离件30的下方的位置，且红外加热件20和置物件40分别位于红外透波隔离件30的两侧，在红外透波隔离件30的延伸方向上，倾斜面33从上向下逐渐朝向光滑平面延伸，由此使倾斜面33和光滑平面之间形成锐角，从而可以将红外加热件20发出的红外线折射到置物件40上，实现能量的充分利用。
在一些示例中，倾斜面33包括多个，多个倾斜面33沿红外透波隔离件30的延伸方向间隔布置，通过设置多个倾斜面33，可以减小红外透波隔离件30的厚度，便于红外透波隔离件30的制造与装配，还可以对多个倾斜面33的倾斜角进行调节，以使红外加热件20发出的红外线均匀的折射到置物件40上，进而使得置物件40上食物的加热均匀，口感好，烹饪效果好。其中，相邻两个倾斜面33圆滑过渡连接，以使红外线辐射在两个倾斜面33之间也可以折射至置物件40上，进一步提高红外加热件20的利用率。
在一些可选的示例中，相邻两个倾斜面33也可以通过平面连接，以便于红外透波隔离件30的制造，提高制造精度；或者多个倾斜面33中的一部分通过平面连接，另一部分圆弧过渡连接，以适于对红外线的折射为宜，在此不再限定。
在一些可选的示例中，倾斜面33包括多个，每个倾斜面33与光滑平面之间的夹角相同，例如，多个倾斜面33包括第一倾斜面331、第二倾斜面332和第三倾斜面333，第一倾斜面331与水平面之间的夹角为α，第一倾斜面331与水平面之间的夹角为β，第一倾斜面331与水平面之间的夹角为γ，其中，α＝β＝γ，由此可以简化红外透波隔离件30的结构，便于红外透波隔离件30的制造和装配。
在另一些可选的示例中，多个倾斜面33与光滑平面之间的夹角不同，以使红外加热件20发出的红外线可以均匀的折射到置物件40上，进而使得置物件40上食物的加热均匀，提高烹饪效果，提升烹饪口感。
例如，多个倾斜面33与光滑平面之间的夹角在红外透波隔离件30的延伸方向上从靠近置物件40的一侧到远离置物件40的一侧依次减小，如图2所示，多个倾斜面33包括第一倾斜面331、第二倾斜面332和第三倾斜面333，第一倾斜面331、第二倾斜面332和第三倾斜面333从下向上间隔布置，第一倾斜面331与水平面之间的夹角为α，第一倾斜面331与水平面之间的夹角为β，第一倾斜面331与水平面之间的夹角为γ，其中，α＞β＞γ。优选地，α＝85°，β＝80°，γ＝75°。
根据本发明的一个实施例，红外透波隔离件30为玻璃件，玻璃具有良好的透波性能，且来源广泛，成本低，制造工艺成熟，便于推广应用。
根据本发明的一个实施例，本体10内设有支撑框架50，红外透波隔离件30的边沿与支撑框架50固定连接，由此实现红外透波隔离件30的固定，且仅将红外透波隔离件30的边沿进行固定，便于红外透波隔离件30对红外线的透射和折射，避免对红外线产生遮挡，影响烹饪加热效果。
在一些示例中，第一侧面31的与支撑框架50连接处形成光滑的平直段，即该处第二侧面32与第一侧面31平行，且在该处第一侧面31与第二侧面32均沿竖直方向延伸，以便于红外透波隔离件30的固定安装，支撑框架50可以形成纵截面为U形的开口槽，红外透波隔离件30可以直接插接至支撑框架50内，从而简化安装的复杂度，提高装配效率，同时提高装配后的密封性和稳定性，以避免置物件40上的滴落物进入红外加热件20的放置区，影响使用性能。
根据本发明的一个实施例，置物件40为格栅状，本体10还包括承接盘60，承接盘60设置在置物件40的下方，承接盘60可以用来承接置物件40上的滴落物，例如食物上的油汁透过格栅状的置物件40，可以滴落在承接盘60上，承接盘60与本体10可拆 卸连接，由此便于将承接盘60内的滴落物倒掉排出，提高使用的便利性。
根据本发明的一个实施例，烹饪器具100为无烟红外烤架，下面以无烟红外烤架为例，描述根据本发明的一个具体的实施例。
无烟红外烤架包括：本体10和红外透波隔离件30，本体10包括红外加热件20、置物件40、支撑框架50和承接盘60。
置物件40为格栅状，红外加热件20设置在置物件40的下方，且红外加热件20位于置物件40在红外加热件20所在平面的投影的外侧，置物件40在承接盘60所在平面的投影落入承接盘60内，由此可以使置物件40上的滴落物完全滴落在承接盘60上。
红外透波隔离件30通过支撑框架50固定在本体10上，红外透波隔离件30用于将置物件40和红外加热件20间隔开，从而可以避免置物件40上的滴落物落入红外加热件上20。
红外透波隔离件30包括相背的第一侧面31和第二侧面32，第二侧面32背向红外加热件20设置，第二侧面32形成光滑平面，且第二侧面32沿竖直方向延伸布置，第二侧面32与置物件40的延伸方向垂直。
第一侧面31朝向红外加热件20设置，第一侧面31上具有相对于第二侧面32倾斜设置的倾斜面33，倾斜面33包括第一倾斜面331、第二倾斜面332和第三倾斜面333，第一倾斜面331、第二倾斜面332和第三倾斜面333从下向上间隔布置，且相邻两个倾斜面33圆滑过渡连接，其中，第一倾斜面331与水平面之间的夹角为α，第一倾斜面331与水平面之间的夹角为β，第一倾斜面331与水平面之间的夹角为γ，α＝β＝γ＝83°，由此使得红外透波隔离件30可以对红外加热件20发出的红外线起到折射作用。
根据本发明实施例的无烟红外烤架，红外透波隔离件30可以对红外加热件20起到防护的作用，通过在红外透波隔离件30的第一侧面31上设置倾斜面33，从而使得红外透波隔离件30可以对红外加热件20发出的红外线进行折射，以使绝大部分红外线辐射到置物件40上，对置物件40上的食物进行加热烹饪，避免红外线辐射到置物件40以外的位置，由此使得红外加热件20发出的红外线可以被充分利用，提高了能量利用率，提高用户的使用体验，进而提高了产品的市场竞争力。
