Description

[0001] The invention relates to a cooking appliance door, comprising a front pane with an opaque viewing frame and a non-opaque viewing cutout incorporated in the viewing frame, wherein the viewing cutout and at least one region of the viewing frame adjacent to the viewing cutout have an identical pattern.

[0002] Such a pane, referred to as a front panel, is known from publication CH 696 368 A5. In an oven door, a panel is arranged at a distance from the front panel. By adapting the size and shape of the panel to the requirements of the respective appliance type, it is possible to design the front panel consistently for different appliance types, thus simplifying the manufacturing process.

[0003] A contact guard for a stove with an oven door that closes a baking or roasting oven is known from DE 75 14 000 U. Thin plastic bars are attached to the outer surface of the door, spaced closely apart, and extend across the entire door surface.

[0004] From the document DE 10 2007 058 944 A1 a cooking appliance is known with a cooking chamber delimited by walls and having a loading opening, a door for closing the loading opening and a lighting device for illuminating the cooking chamber.

[0005] From DE 103 44 442 B3, a cooking appliance door with an inner pane made of borosilicate glass is known, on which at least one paint layer made of a high-temperature-resistant non-enamel paint with organic or inorganic binders and at least one infrared-reflecting layer are applied in such a way that the paint layer is applied directly on one side of the inner pane and the infrared-reflecting layer is applied on this paint layer.

[0006] Panes of the type mentioned are known which have a full-surface viewing frame and a pattern in the viewing cutout. For example, panes with a black viewing frame are known which have a dot pattern in the viewing cutout to visually loosen up the transition between the viewing frame and the viewing cutout. Panes with a white viewing frame are also known in which the viewing cutout is covered with a white pattern of horizontal lines. The disadvantage of panes with the white viewing frame is that they make the cooking chamber visible through the viewing cutout appear smaller than panes with the black viewing frame. One way of making the cooking chamber appear higher with the white viewing frame is to provide the left and right edges of the viewing cutout with a black line and to extend this black line downwards into the white viewing frame.However, the optical effect is not very great, and the white design is disturbed in terms of color.

[0007] It is the object of the present invention to at least partially avoid the above-mentioned disadvantages.

[0008] This object is achieved according to the features of claim 1. Preferred embodiments can be found in particular in the dependent claims.

[0009] The problem is solved by a cooking appliance door comprising a front panel with an opaque viewing frame and a non-opaque viewing cutout incorporated in the viewing frame, wherein the viewing cutout and at least one region of the viewing frame adjacent to the viewing cutout have a similar pattern. The pattern in the at least one adjacent region has a background that appears darker than the rest of the viewing frame and is similar in color to the viewing cutout in an unlit cooking chamber.

[0010] For example, the pattern can be used at the viewing area to make it difficult to see into the unlit cooking chamber while not significantly obstructing the view into the lit cooking chamber. If the pattern is continued in the adjacent area, the adjacent area's connection to the viewing area is further emphasized.

[0011] At least one adjacent area appears darker than the rest of the visible frame. This allows the color to be matched to the cooking chamber, particularly in the case of a light-colored visible frame, which previously made the cooking chamber appear smaller. The adjacent area can be patterned, e.g., multi-colored, or have a uniform design. In a simple, special case, for example, the viewing window can be unpatterned and the adjacent area can be uniformly filled in a color similar to the cooking chamber, e.g., a shade of gray, while the visible frame can be white or whitish, for example.

[0012] The viewing frame (also called a viewing window) is an opaque application applied to the front and / or back of the front panel for the purpose of concealing a flange of the cooking appliance muffle when the door is closed. The viewing frame can be printed on the front panel or applied as a film, for example. The viewing frame can also have a self-supporting frame covering the front panel, e.g., made of plastic or metal. The viewing frame can completely or partially surround the viewing cutout.

[0013] The color similarity of the area adjacent to the viewing area to the viewing area of ​​an unlit cooking chamber creates a uniform impression for the observer of these two surfaces and suggests that the cooking chamber is enlarged into the adjacent area. This apparent enlargement is optically assumed to apply to the entire adjacent area and is therefore very effective.

[0014] Another design feature is that the pattern is a line pattern.

[0015] An alternative design is for the pattern to be a dot pattern.

[0016] Another embodiment provides that the pattern in the at least one adjacent area has a darker background, i.e., the pattern is lighter or has a lighter color than the background. Thus, especially for light patterns that make the cooking chamber appear smaller, the background is adapted to the usually dark or darker, unlit cooking chamber.

[0017] It is a special design that the background is similar in color to the unlit cooking chamber, so that a very similar appearance to the viewing window is achieved, especially with the same pattern.

[0018] Another feature is that the spaces between the lines of the pattern in the adjacent area are completely filled with the background. This creates a particularly clean and unobtrusive visual enlargement of the cooking space.

[0019] Another option is for the background to be a gray shade (pure gray) or a grayish shade (with a color cast). This is easy to determine and produce and is similar to the unlit cooking chamber. A grayish shade can be, for example, anthracite, mouse gray, etc. The gray or grayish shade can be a RAL or HKS color, for example.

[0020] Another feature is that the color of the unlit muffle essentially corresponds to the color of the light when incident at an angle (from the side or from above). This takes into account the fact that in most kitchens, kitchen windows are arranged to the side of a kitchen unit.

[0021] Another option is for the viewing frame to be pure white or whitish (with a color cast). This creates a high color and / or brightness contrast that makes the background of the adjacent area particularly unobtrusive, and any slight color differences from the color of the cooking chamber visible through the viewing window are only slightly noticeable or not at all. The white or whitish color can be a RAL or HKS color, for example. However, other bright colors are also possible.

[0022] The problem can be solved in particular by a front pane with a partially white or whitish viewing frame, the viewing section of which is covered with a pattern, in particular a horizontal line pattern of the same color, and wherein the adjacent area has the same line pattern as the viewing section, but has a background for the pattern that is color-matched to the cooking chamber.

[0023] The following figure schematically describes the invention in more detail using an exemplary embodiment. For clarity, identical or equivalent elements may be provided with identical reference numerals.

[0024] The figure shows a front view of a front panel 1 according to the invention for a cooking appliance door T. The front panel has a rectangular base plate 10 made of glass, into which two holes 3 for the passage of a door handle are made just before an upper edge 2. The cooking appliance can be, for example, an oven.

[0025] The front of the front panel 1 is covered with an opaque frame 4. The frame 4 can, for example, be printed, e.g., screen printed, or made of film. The frame 4 borders on all sides by the side edges (the upper edge 2, a lower edge, a left and a right edge) of the front panel 1. A rectangular, non-opaque viewing cutout 5 or viewing window is incorporated into the frame 4, which, when the cooking appliance door is closed, allows a view from the outside into the cooking chamber, which is closed by the cooking appliance door. In this case, the frame 4 prevents a view of a cooking appliance flange.

[0026] The viewing cutout 5 is covered with a pattern of horizontal, equidistantly arranged lines 6. These lines 6 merge laterally into the viewing frame 4 and, for a clear, calm design, are the same color (here: white) as at least the adjoining area of ​​the viewing frame 4. The lines 6 are preferably applied at the same time and using the same means as the viewing frame (e.g. during the same printing process, etc.). In an unlit cooking chamber, the lines 6 make it more difficult to see into the cooking chamber because, firstly, the viewing area is somewhat reduced and, secondly, a view into the dark cooking chamber is distracted by the bright lines 6. In a lit cooking chamber, on the other hand, the difference in brightness to the lines 6 and thus the distraction from perception is no longer as great and details of the cooking chamber are also clearly visible, so that the lines do not significantly impede visibility.This effect is particularly noticeable when the color of lines 6 is brighter than the color of the unlit cooking chamber.

[0027] In addition to its surrounding, homogenously white surface area, the viewing frame 4 has an opaque area 7 adjacent to a lower edge of the viewing section 5, which is designed differently than the homogenously white surface area. In particular, this adjacent area 7 is covered with the same line pattern as the viewing section 5. However, the corresponding lines 6 of the adjacent area 7 are not unoccupied as in the viewing section 5, but are covered by a homogenously gray background 8, which is indicated here by hatching. The background 8 can be in the form of a print, a film, etc. As a result, the adjacent area 7 appears darker as a whole than the rest of the viewing frame 4. In general, the pattern (here the lines 6) in the adjacent area 7 can have a darker background 8.For particularly effective optical enlargement of the cooking chamber downwards by adjusting the appearance of the adjacent area 7 to the viewing section 5 in the case of an unlit cooking chamber with oblique light incidence from outside, the background 8 is designed in a color similar to that of the unlit cooking chamber.

[0028] For a particularly clean design, the background 8 is applied in the adjacent area in such a way that spaces between the lines 6 of the line pattern are completely filled with the background 8.

[0029] The front pane 1 can, for example, be manufactured in such a way that the front pane 1 is first positioned in front of an open cooking chamber of the cooking appliance T with the oven lighting switched off. The front pane 1 can already be covered with the viewing frame 4 and the pattern. A color is then selected that is at least similar to a color of a cooking chamber viewed through the front pane 1. This can be done by automatic color determination or color matching, e.g. using a RAL or HKS fan. Subsequently, for this front pane 1 or subsequent panes, a layer in the selected color can be applied to an area 7 of the front pane 1 that borders a viewing section of the front pane 1.

[0030] When the viewing frame 4 and the lines 6 of the pattern are applied to the front of the windscreen 1, the background 8 can in particular first be applied over the entire surface of the windscreen 1, e.g., by printing, and then the viewing frame 4 and the lines 6 can be applied together. When applied to the rear, the viewing frame 4 and the lines 6 can in particular first be applied together and then the background 8 can be applied over the entire surface of the lines 6 of the adjacent area 7, e.g., by printing. This is preferably done such that the background 8 ends on one of the lines 6 in the area of ​​the line pattern, which results in a particularly clean appearance.

[0031] Of course, the present invention is not limited to the embodiment shown.

[0032] The pattern can also be a dot pattern or another suitable pattern. For example, the dot pattern can approximate a line pattern by arranging the dots in a line-like pattern.

[0033] The color selection of the display frame, lines, and background is not limited to white and gray. These achromatic colors can also have a color cast. Alternatively, colors such as yellow or silver for the line pattern and display frame, and brown for the background, can be used. The color selection, especially for the display frame, can take into account, for example, color matching to a device's frame.
