Definitions

• the present invention relates to a panel absorbing and / or reflecting microwaves, a glazing and shutter means for an oven using microwaves, comprising such a panel, and a method of obtaining a such a panel, and such glazing and such shutter means.
• Microwaves are electromagnetic radiation, used in industry in many technical fields. They are also used daily by professionals or individuals, in the field of household appliances, and more particularly heat treatment devices, such as ovens.
• microwaves there are ovens commonly known as “microwaves” because they only use microwave radiation for heating and rapid cooking of food, and so-called “mixed” or “combined” ovens because they use microwaves and one or more other sources of heat production, such as for example an electrical resistance or an infrared source, in opposition to so-called “traditional” ovens using only one type of heat source, such as for example gas or electricity.
• the ovens using microwaves, generally include a cooking chamber, which confines the radiation, and means for closing an opening through which the products to be heat treated are placed in the oven, which comprise, or are, usually a door, capable of limiting or preventing the escape of microwaves out of the enclosure.
• the door includes glazing that is little or not transparent to microwaves by the use of shielding.
• the means for shielding glazing units comprise or consist of a network of conductors forming a mesh, which has the advantage of retaining a certain optical transparency, in the visible range, and a certain opacity to micro- waves.
• the mesh size of such a network is generally between 1 and 2 mm, which represents 10% of the wavelength of microwaves used in an oven, which have a wavelength of 12 cm for a frequency generally fixed at 2.5 GHz in the most ovens. This allows about 90% of the microwaves generated in the oven to be reflected.
• the shielding means can be a metal grid, fixed to the metal part of the frame of the microwave oven door, using enamel or paint, as described in document DE3714122, or else a wire mesh, arranged between an outer pane and an inner pane, the space being joined using silicone, or alternatively an expanded metal plate, obtained by shearing and concomitant stretching of a metal plate, to form a lattice metallic having a hexagonal or diamond-shaped pattern, as described in the document JP 2005273977, or else a metallic fabric, woven from conductive wires, as described in the document US2018054860.

Furthermore, not only does such glazing have a perfectly unsightly appearance, it also gives the oven, which includes such glazing, a connotation of "microwave oven", which may prove to be negative for certain users, especially in the case of ovens mixed.
