Description

微波炉的腔体和微波炉
技术领域
本发明涉及微波炉领域，特别涉及一种微波炉的腔体和微波炉。
背景技术
微波炉是用微波加热食品的现代化烹调灶具，如常见的圆形微波炉中，该圆形微波炉的腔体也是圆形的，以圆形微波炉为例，该圆形腔体包括一个圆柱形的腔体本体和一个设在该圆形腔体的上端边缘外侧、呈水平设置的翻边，该翻边采用焊接方式连接于该圆形腔体上，而由于焊接方式会导致翻边起皱，这将造成翻边的表面平整度下降，然而翻边上表面需要与圆形微波炉的门体配合（微波炉的炉盖中的组件），由于翻边的上表面平整度不足，造成腔体与门体配合后之间的缝隙过大，而影响微波炉正常使用。
发明内容
本发明的主要目的是提出一种微波炉的腔体，以提高微波炉腔体的上端边缘的翻边表面的平整度。
为实现上述目的，本发明提出的一种微波炉的腔体，包括横截面为圆形的腔体本体以及设置于所述腔体本体的上端边缘外侧、呈水平设置的翻边，所述腔体本体与所述翻边为一体成型设置。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明，若本发明实施例中有涉及方向性指示（诸如上、下、左、右、前、后……），则该方向性指示仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
本实施例在此提出了一种微波炉（未示出），该微波炉包括有磁控管，用于激发微波；波导组件，用于将微波导入腔体中；腔体，内可放置内胆锅，内胆锅可接收微波能量以加热放入该锅内的食物，搁板 用于盛放待加热物品，其与驱动电机连接，顶盖 ，用于打开/关闭腔体，顶盖包含有门体 ；当顶盖关闭腔体时，门体与腔体本体配合。
参照图1，本实施例的微波炉所采用的腔体1包括：横截面为圆形的腔体本体10以及设置于所述腔体本体10的上端边缘外侧、呈水平设置的翻边20，该翻边20是与腔体本体10一体成型制成。
本实施例中，该微波炉的腔体中，其腔体本体10是与翻边20为一体成型设置，而使得翻边20的平整度可以得到有效保证，当顶盖关闭腔体时，门体抵接到与腔体的翻边20上，顶盖的门体与腔体1的翻边20可实现无缝接触或者缝隙极小，进而降低从顶盖的门体与腔体1的翻边20之间的缝隙中泄露的微波量。
腔体本体10与翻边20一体成型的方式有多种，如可采用拉伸方式一体成型，冷轧方式一体成型，注塑方式一体成型等常见一体成型方式，鉴于加工的方便性与经济性的综合考虑，于本实施例中，腔体本体10与翻边20采用一体拉伸成型方式成型。
进一步地，结合参考图2和图3，本实施例中，翻边20具有竖向折边30，即在翻边20的边缘处设置一个向上延伸的延伸边，竖向折边30可与翻边20一体成型或者分体成型，考虑到加工的方便性，本实施例优选采用竖向折边30与翻边20一体成型，如一体拉伸成型。其中竖向折边30上可以设有多个的连接孔31，用于与外部物件相连，例如，本实施例可以在腔体的翻边20外侧包裹一紧固圈，在紧固圈上内侧设置卡扣，通过卡扣卡接于该连接孔31中，以实现紧固圈固定包裹于腔体外侧。
进一步地，本实施例中，翻边20上还可以开设弧形压型槽21。弧形压型槽21是在翻边20上从翻边20上表面向下凹陷而形成的一圆弧形凹槽，相当于给翻边20设置了加强筋，可以使翻边20具有更好较好的强度，而不容易变形。
进一步地，本实施例中，腔体本体10的底壁还设有多级台阶11，具体地，在制作腔体本体10时，在腔体本体10的底部形成多个从底部到顶部方向直径依次增大的环形挡台，以形成多级台阶11，以便将搁板固定放置于该多级台阶11之间形成的环形挡台上。当驱动电机带动搁板转动时，搁板会处在多级台阶11所能限定的预定区域内转动。另外，多级台阶也可以对放入腔体本体10内的内锅胆的底部进行限位固定，可谓一举两得。
当面临烹饪食物量的不同选择时，会选择不同尺寸的锅内胆，而随着锅内胆的增大，必然需要更大尺寸的腔体本体10，自然，翻边20的尺寸也要随之改变，本实施例中，环形翻边20与腔体本体10的直径差的范围可以设定在6-70mm。换言之，即环形翻边20的宽度范围为3-35mm。本实施例设置这样一个范围，不仅是因为实际中因为锅内胆大小变化的原因，更是基于加工方便性与加工成本的综合考量。
本实施例中，腔体本体为一体结构。现有技术中，腔体本体10大多是采用焊接方式进行一体成型制作而成，如沿腔体本体10的轴向方向会存在一条焊缝，而焊接会造成腔体本体10的热变形，影响腔体本体10形状的精确度，而本实施例的腔体本体10可以为一体结构，如可采用一体拉伸成型或冷轧等常见一体成型方式，考虑加工的方便性，本实施例优选采用一体拉伸成型方式来制作腔体本体10。
本实施例中，腔体本体10的底部设置有馈波口。微波是微波炉的底部馈入微波至腔体本体10中，而现有技术中，由于微波炉腔体是方形的，馈波口一般是设置在腔体本体的侧壁上，本实施例中，将馈波口设置在腔体本体10的底部，是当将磁控管安装在腔体本体10的底部的灵活选择方式。当然，在一些实施例中，馈波口也可以设置在腔体本体10的侧壁上。
此外，本实施例中，水平翻边20上开设有用以安装门钩的门钩孔22，门钩孔22位于上述的两对称设置的压型槽21之间，可在微波炉的顶盖上对应设置一门钩，通过门钩与门钩孔22的配合，方便打开/关闭腔体本体10。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
