Abstract
The invention discloses a microwave shielding structure for a microwave oven. The microwave shielding structure comprises an observation window and/or an exhaust window; a plurality of mesh holes are formed on surfaces of the observation window and the exhaust window; the mesh holes are hexagonal; the surface of the observation window and/or the exhaust window is a cambered surface; and the mesh holes are arranged into honeycombs on the cambered surface. The observation window and/or the exhaust window is drawn and formed by a metal plate of which the surface is provided with a plurality of hexagonal holes, so that the mesh holes on the observation window and/or the exhaust window are arranged into honeycombs. In the process of drawing and forming in an equivalent state, by comparing the drawn and formed metal plate provided with hexagonal holes and the drawn and formed metal plate provided with circular holes, due to interaction force among the hexagonal holes, the deformation of the holes is greatly reduced relative to the circular holes, the microwave leakage is reduced by about 20 percent, and a condition that the microwave energy leakage exceeds an acceptable range due to large hole deformation is avoided. The microwave shielding structure for the microwave oven is simple and reasonable in structure, low in microwave leakage, and safe and reliable to use.
Description
Technical field
The present invention relates to a kind of micro-wave oven, particularly a kind of microwave shielding structure for microwave oven.
Background technology
Along with the development of technology and the raising of people's living standard, people also require to bring up to demand to its fashion, convenience, the aspect such as energy-conservation from only meeting using function to the requirement of product.The present invention devises a kind of type shape side for micro-wave oven observation window or steam vent and tries.See Fig. 1, Fig. 2, not only for the fire door of conventional microwave oven, be provided with the panel beating that surface arranges some circular ports in fire door 10, this panel beating can be used as observation window but also maskable major part microwave, its circular port 10.1 diameter D1 is between 1.0mm ~ 5.0mm, and adjacent two circular hole spacing L1 are between 0.4 ~ 1.0.But the fire door due to the type micro-wave oven is tabular, so circular hole size can ensure.If when micro-wave oven is novel microwave oven spherical in shape, because its bonnet is hemispherical, when being hemispherical micro-wave screening cover by the panel beating that is provided with circular port by drawing and forming, circular port can become very irregular because of drawing process, and finally bigger than normal from this some holes microwave energy out, exceed tolerance interval.
Summary of the invention
Object of the present invention aims to provide a kind of simple and reasonable, microwave shielding structure for microwave oven that microwave leakage amount is little, safe and reliable, to overcome weak point of the prior art.
By a kind of microwave shielding structure for microwave oven that this object designs, comprise observation window and/or exhausting window, observation window and exhausting window surface are provided with some mesh, it is characterized in that mesh is hexagon.
The surface of described observation window and/or exhausting window is cambered surface, and mesh is arranged into cellular in cambered surface.
Described micro-wave oven comprises stove seat and is hemispheric bonnet; Bonnet comprises in hemispheric micro-wave screening cover, forms described observation window after micro-wave screening cover surface is provided with some mesh.User's mesh that can pass through on observation window observes the situation of food in gastronomical process in furnace chamber.
The panel beating deep drawn that described observation window is provided with some regular hexagon holes by surface is shaping.
The inscribed circle diameter D2 in the regular hexagon hole on the panel beating before the non-deep drawn of described observation window is shaping is 1.0mm-5.0mm; Distance L2 between adjacent two mesh is 0.4mm-1.0mm.
The inscribed circle diameter D2 in described regular hexagon hole is 1.5mm-3.0mm; Distance L2 between adjacent two mesh is 0.5mm-0.8mm.
The inscribed circle diameter D2 in described regular hexagon hole is 1.5mm, 2.0mm, 2.5mm or 3.0mm; Distance L2 between adjacent two mesh is 0.5mm, 0.6mm, 0.7mm or 0.8mm.
Observation window of the present invention and/or exhausting window are provided with the panel beating drawing and forming in some regular hexagon holes by surface, make the mesh on observation window and/or exhausting window be cellular arrangement.When same condition drawing and forming, adopt the panel beating that is provided with regular hexagon hole with adopt be provided with circular port panel beating drawing and forming compared with, due to the interaction force between regular hexagon hole, the modification amount in hole can be reduced greatly relative to circular port, microwave leakage is also measured little by about 20%, avoids because hole modification amount is large and causes microwave energy leakage to exceed tolerance interval.It is simple and reasonable, microwave leakage amount is little, safe and reliable.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
See Fig. 3-Fig. 4, this microwave shielding structure for microwave oven, comprise surface and be provided with some mesh observation windows, mesh is hexagon.The surface of observation window is cambered surface, and mesh is arranged into cellular in cambered surface.
Micro-wave oven comprises stove seat 2 and is hemispheric bonnet 1; Bonnet comprises in hemispheric micro-wave screening cover 3, forms described observation window after micro-wave screening cover surface is provided with some mesh.The panel beating deep drawn that observation window is provided with some regular hexagon holes 3.1 by surface is shaping.
Inscribed circle (see center line in Fig. 5) the diameter D2 in the regular hexagon hole 3.1 on the panel beating before the non-deep drawn of observation window is shaping is 1.0mm-5.0mm; Distance L2 between adjacent two mesh is 0.4mm-1.0mm.
Only sub-fraction is drawn in the mesh figure on above-mentioned micro-wave screening cover 3 surface.
The optimization range of the inscribed circle diameter D2 in above-mentioned regular hexagon hole 3.1 is 1.5mm-3.0mm; The optimization range of the distance L2 between adjacent two mesh is 0.5mm-0.8mm.The optimal value of the inscribed circle diameter D2 in regular hexagon hole 3.1 is 1.5mm, 2.0mm, 2.5mm or 3.0mm; The optimal value of the distance L2 between adjacent two mesh is 0.5mm, 0.6mm, 0.7mm or 0.8mm.
