    [0005] The main idea of the present invention is that the outer glass panel varies along the complete outer side of the door, on the one hand, and the inner glass panel varies along the substantially complete inner side of the door, on the other hand . The circumferential sides of the door are covered by the door frame. Additionally, the outer portions of the inner side of said door are also covered by the door frame. Thus, the outer glass panel, the inner glass panel and the door frame form the door compartment, wherein the wave blocking system is arranged inside said compartment. The door has a compact shape with smooth surfaces. Since the wave blocking system is adjacent to the outer side of the inner glass panel, said inner glass panel is relatively large and the door allows an improved view through said door to a cavity of the microwave apparatus.
    [0006] According to the preferred embodiment of the present invention, the door frame is made of plastic.
    [0007] Furthermore, at least one intermediate glass panel can be arranged between the wave blocking system and the outer glass panel.
    [0008] According to a preferred embodiment of the present invention, the wave blocking system includes a G-shaped profile.
    [0009] In particular, the wave blocking system includes at least one lamella structure.
    [0010] For example, the lamella structure is arranged next to a G-shaped profile opening of the wave blocking system.
    [0011] Preferably, the lamella structure is disposed adjacent to an outer side of the inner glass panel. The inner glass panel can have a relatively high thickness.
    [0012] In addition, a gap between the circumferential sides of the inner glass panel and the door frame can be filled by a gasket. This contributes to a smooth surface of the door.
    [0013] Furthermore, an upwardly bent portion of the wave blocking system penetrates at least partially into the gap between the circumferential sides of the inner glass panel and the door frame.
    [0014] In particular, the door is an oven door for a microwave oven.
    [0015] Furthermore, the present invention relates to a microwave apparatus, wherein said microwave apparatus includes at least one port mentioned above.
    [0016] For example, the microwave apparatus is a microwave oven.
    [0017] Preferably, the microwave apparatus comprises a cavity and a front frame, wherein the front frame circumferentially surrounds a front opening of the cavity.
    [0018] Furthermore, a gap between the front frame and the front opening of the cavity is filled with a gasket.
    [0019] Finally, the door wave blocking system can extend in parallel with the gap between the front frame and the front opening of the cavity in a closed state of said door.
    [0020] New and inventive features of the present invention are presented in the appended claims.
    [0021] The present invention will be described in greater detail with reference to the drawings, in which FIG. 1 illustrates a schematic sectional side view of an oven door for a microwave oven or a multifunctional oven with microwave heating function. According to a preferred embodiment of the present invention, eFIG 2 illustrates a schematic sectional view in perspective of an oven door upper part for a microwave oven or a multifunctional oven with microwave heating function according to an embodiment of the present invention.
    [0022] FIG 1 illustrates a schematic sectional side view of an oven door 10 for a microwave oven or a multifunctional oven with microwave heating function according to a preferred embodiment of the present invention. The oven door 10 is connected to a microwave oven. In FIG 1 the oven door 10 is in a closed state.
    [0023] The oven door 10 comprises an outer glass panel 12, an inner glass panel 12, a first intermediate glass panel 16, a second intermediate glass panel 18, a door frame 20 and a locking system. wave 22. The microwave oven includes an oven cavity 28 and a front frame 30.
    [0024] The outer glass panel 12 forms the outer side of the oven door 10 and is connected to the door frame 20. The area of the outer glass panel 12 is larger than the area covered by the door frame 20. Thus, the outer glass panel 12 completely covers the door frame 20. The inner glass panel 12 forms the substantial part of the inner side of the oven door 10. The circumferential sides of the inner glass panel 12 are surrounded by the door frame 20. In this example, the door frame 20 is made of plastic materials. The door frame 20 can be formed as a single piece or composed of several frame components. The 22 door locking system is made of sheet metal.
    [0025] The door locking system 22, the first intermediate glass panel 16 and the second intermediate glass panel 18 are arranged between the outer glass panel 12 and the inner glass panel 12. The wave locking system 22 is disposed adjacent to an outer side of the inner glass panel 12. The first intermediate glass panel 16 is disposed opposite the door locking system 22. In turn, the second intermediate glass panel 18 is disposed opposite the first intermediate glass panel 16. The door frame circumferentially also surrounds the wave blocking system 22, the first intermediate glass panel 16 and the second intermediate glass panel 18.
    [0026] The wave lock system 22 includes a G-shaped profile that extends parallel to the front frame 30 of the microwave oven. The G-shaped profile forms a rectangular frame surrounded by the door frame 20. A gap of the G-shaped profile extends in parallel with a gap between the oven cavity 28 and the front frame 30 of the microwave oven. A profile section beyond the gap of the G-shaped profile includes a lamella structure 24. The lamella structure 24 is disposed adjacent to the outside of the inner glass panel 14. The plane of the lamella structure 24 extends at parallel with the inner glass panel 14.
    [0027] A circumferential gap between the inner glass panel 14 and door frame 20 is filled by a gasket 26. In addition, said gasket 26 partially surrounds an upwardly bent portion of the wave locking system 22. Said portion folded up surrounds the wave blocking system 22 and partially penetrates the gap between the inner glass panel 14 and the door frame 20.
    [0028] FIG 2 illustrates a schematic sectional view in perspective of an upper part of the oven door 10 for the microwave oven or a multifunctional oven with microwave heating function according to a preferred embodiment of the present invention.
    [0029] In particular, FIG 2 shows the geometric properties of the wave blocking system 22, including the lamella structure 24. In addition, the arrangements of the outer glass panel 12, the inner glass panel 12, the first panel of intermediate glass 16, second intermediate glass panel 18 and door frame 20 are shown. For the sake of clarity, gasket 26 is not shown in FIG 2.
    [0030] The oven door 10 allows an improved view through said oven door 10 to the oven cavity 28. The oven door 10 has a compact shape with smooth surfaces. Since the inner glass panel 14 varies over the almost complete inner side of the oven door 10, said inner side can be easily cleaned. The oven door 10 allows for a leakage of less than 1 mW/cm2. This value results from the structure and profile of the wave blocking system 22.
    [0031] The present invention is not restricted to the oven door 10 for the microwave oven. In general, the present invention relates to a door for a microwave apparatus and a corresponding microwave apparatus.
    [0032] Although an illustrative embodiment of the present invention has been described herein with reference to the accompanying drawings, it is to be understood that the present invention is not limited to that precise embodiment, and that various other changes and modifications may be made thereto by one of ordinary skill in the art. technique, without departing from the scope of the invention.
