下面参考附图1到图8详细描述根据本发明实施例的烤箱100。
参考图1到图8，根据本发明实施例的烤箱100包括箱体1和门体2，箱体1内形成具有开口6的烹饪腔3。门体2与箱体1铰接且门体2在打开和关闭开口6的位置之间可转动，其中，箱体1和门体2中的一个上设有密封件4且另一个上设有密封面5，门体1关闭开口6则密封件4环绕开口6、密封面5抵压密封件4。
根据本发明实施例的烤箱100，在门体2关闭后，门体2的密封面5充分与密封件4相抵压，能够实现烤箱100良好的密封性能，有力提高烤箱100的安全性，利于降低烤箱100的能耗。
可选地，参照图3，门体2上设置密封件4，箱体1的对应位置具有密封面5，门体2在封闭开口6时可与密封件4相互抵接，从而使密封件4产生一定的变形和压缩，进而降低门体2与箱体1的气隙，实现门体1和箱体2的密封。
可选地，参照图1、图7和图8，箱体1上连接有密封件4，门体2上形成有密封面5，门体2在封闭开口6时，密封面5可与密封件4充分抵压在一起，从而将密封件挤压产生一定的形变和压缩，从而降低门体2和箱体1的气隙，实现门体1和箱体2的密封。
可选地，参照图2和图3，密封面5的远离门体2与箱体1的铰接位置7的一端对密封件4的压缩量大于密封面5的靠近铰接位置7的一端对密封件4的压缩量，需要解释的是，密封件4的压缩量是指沿着密封面5对密封件4挤压的方向，密封件4未受到挤压时的自然长度与密封件4受到挤压并变形最大时的长度之间的差值。
门体2铰接于箱体1上，在箱体2温度升高后，门体2势必因为热胀冷缩的作用发生变形，但是由于门体2和箱体1有铰接件的连接，所以在靠近铰接位置7的一端，密封面5与密封件4的抵压作用不会产生大的改变。但是，在实际应用和多次试验中发现，门体2在远离铰接位置7的一端，随着箱体2温度的升高，会朝向箱体2的外侧涨开，为了避免密封不良，参照图2和图3，根据本发明的实施例的烤箱100设置在远离铰接位置7的一端，使门体2和箱体1之间的密封面5对密封件4的压缩量更大，以此来应对因热胀冷缩导致的门体2的形变，避免密封面5与密封件4的脱离，从而保证烤箱100的密封效果。
根据本发明实施例的烤箱100，由于远离门体2与箱体1的铰接位置7的一端密封面5对密封件4的压缩量更大，在箱温升高后，门体2在热涨热缩的作用下发生一定形变后，依然可以对密封件4产生合理的压缩量，从而保证密封效果，预防烤箱100工作之后能量损失，提高烤箱产品的安全性和可靠性。
可选地，参照图1到图3、图6和图7并结合图示的方向，箱体1和门体2的铰接位置7设于箱体1和门体2的下部，而门体2与箱体1的上部，密封面5对密封件4的压缩量相较于门体2下部密封面5对密封件4的压缩量更大，从而避免烤箱100工作后，箱温升高导致门体2的变形后使门体2上部的密封面5与密封面4脱离，从而保证烤箱100的密封效果。
可选地，为实现在远离门体2和箱体1铰接位置7的一端相较于靠近铰接位置7的一端，密封面5对密封件4的压缩量更大，结合图2和图3，可以将门体2设置为从下到上逐渐朝密封件4倾斜的形式，也可以设置密封件4从下到上逐渐加厚的形式，或者，参照图4，可以将门体2上与密封面5对应的门板的压型高度增加，使其更加贴近箱体2，从而加大对密封件4的压缩量。
为适应不同容量的烤箱，并增加方案的可行性，实现较为优良的密封效果，参照图1 和图3，门体2关闭开口6则密封面5的靠近铰接位置7的一端对密封件4的压缩量与密封面5的远离铰接位置7的一端对密封件4的压缩量的差值在1.5mm-4.0mm之间。
可选地，参照图1、图3和图7，结合图示的上下方向，铰接位置7设于门体2的下方，门体2上具有密封面5，箱体1上连接有密封件4，如图7所示，门体2打开状态下，密封件4处于自然状态，未受到来自于密封面5的挤压。如图1和3所示，当门体2关闭时，门体2上部的密封面5对密封件4的压缩量更大，相较于门体2下部的密封面5对密封件4的压缩量，两者的差值在1mm到5mm之间。经过多次试验表明，箱体1上部密封件4的压缩量和箱体1下部密封件4的压缩量之间的差值控制在1mm到5mm之间时，可以更好地应对门体1受热后导致的变形，从而避免门体2上部的密封面5与密封件4的脱离，使温升后门体1向外涨出后依然能保证密封面5与密封件4的紧密结合。
可选地，根据不同的密封件4的尺寸和烤箱100的容量，门体2关闭时，靠近铰接位置7一端密封件4的压缩量和远离铰接位置7一端密封件7的压缩量之间的差值在5mm之上，也可以保障温升后门体2与箱体1之间良好的密封效果。
可选地，参照图1和图3，为实现良好的密封特性，应对门体2的温升变形，门体2关闭开口6则密封面5的远离铰接位置7的一端对密封件4的压缩量在1mm-8mm之间。
在其他实施例中，在远离铰接位置7的一端，密封面5对密封件4的压缩量在8mm之上，也可以有效地应对门体2的温升变形，保障密封面5与密封件4的紧密抵压状态。
为了改善密封效果并保证密封件4的使用寿命，参照图1和图3，门体2关闭开口6则密封面5对密封件4的压缩率在5％-45％之间。需要解释的是，密封件4的压缩率是指密封件4受挤压后的压缩量与密封件4未受到挤压时自然长度的比值。
在一些实施例中，根据不同材质的密封件4的性能，密封件4的压缩率在45％到60％之间，也能够达到较优良的密封效果，同时不影响密封件4本身的使用寿命和性能。
参照图3、图4和图6，密封面5的靠近铰接位置7的一端相对于箱体1外侧面的高度小于密封面5的远离铰接位置7的一端相对于箱体2外侧面的高度。换言之，结合图3和图6所示方向，在靠近箱体1的最内侧门板上，该门板对应上部密封面5的压型厚度，比该门板对应下部密封面5的压型厚度大，在此处，门板的成型工艺简单可行，只需要调整对应模具的尺寸就能够实现。
可选地，参照图3和图6并结合图示方向，门体2外表面沿上下方向延伸，为实现上述的密封效果，靠近铰接位置7的密封面5到门体2外表面的高度t1,比远离铰接位置7的密封面5到门体2外表面的高度t2小，换言之，上部密封面5到门体2外表面的高度t1，相较于下部密封面5到门体2外表面的高度t2小。
为实现优良的密封性能，应对温升形变，参照图6，密封面5的靠近铰接位置7的一端 相对于箱体1外侧面的高度与密封面5的远离铰接位置7的一端相对于箱体1外侧面的高度之间的高度差在1.5mm-4.0mm之间，换言之，在图6所示的实施例中，t1和t2的差值在1.5mm-4.0mm之间。
在其他实施例中，考虑烤箱100的容量变化和门体2的尺寸，密封面5的靠近铰接位置7的一端相对于箱体1外侧面的高度与密封面5的远离铰接位置7的一端相对于箱体1外侧面的高度之间的高度差在1.5mm之下，也可以达到改善密封性能的作用。
参照图1至图3和图7，箱体1上设有环绕开口6用于安装密封件4的安装面8，门体2关闭开口6则密封面5在远离铰接位置7的方向上逐渐朝向安装面8倾斜延伸，换言之，门体2朝向安装面8倾斜设置，从而有效地应对烤箱100温升后门体2的变形，进而有效地避免密封面5与密封件4的脱离。
参照图2，门体2关闭开口6则密封面5相较于安装面8的倾斜角度α在0.05°-0.8°之间，换言之门体2上具有密封面5的内表面与安装面8的倾斜角度α在0.05°-0.8°之间。
在其他实施例中，门体2沿上下方向延伸，安装面8沿上下方向延伸，并且门体2上具有密封面5的内表面由下向上逐渐朝向安装面8倾斜延伸，其中，门体2的内表面相对于门体外表面的倾斜角度α在0.05°以下。
可选地，参照图1和图7，密封件4的横截面为直径在15mm到26mm之间的圆。
参照图4到图6，密封面5为与密封件4对应的环形，密封面5设于门体2上，且门体2上设有凸筋9，凸筋9位于密封面5的内侧，凸筋9适于抵接开口6的四周。
可选地，参照图4，凸筋9为环形，凸筋9抵接于开口6的四周，起到一定的密封效果，防止烤箱100的内部高温对密封件4造成的损伤，从而提高烤箱100的可靠性。
参照图7和图8，密封件4包括密封圈10和连接件11，连接件11与密封圈10相连，其中，开口6周围设于卡孔12，连接件11与卡孔12卡接。
参照图8，连接件11可以为膨胀扣，连接件11的一端连接于密封圈10上，另一端卡入卡孔12，卡孔12设置于开口6周围的箱体1上，并且连接件11的另一端与卡孔12的周壁充分卡接，从而实现密封圈10与箱体1之间的可靠连接，结构简单，易于实现。
可选地，参照图1和图7，密封圈10为空心管状结构。
总之，根据本发明实施例的烤箱100，相较于传统技术，具有密封性能高，结构可靠稳定，易于实现，改进成本低的优点。
