Definitions
- the invention relates to a microwave-tight stove lamp for installation in a wall of a stove muffle delimiting a cooking space, with at least one light source, in particular an incandescent lamp, associated with each lamp, with the latter being aligned along a central axis, in particular a screw axis, with the lamp holder the lamp-holding metallic housing, a connecting flange connected to the housing and rotating in one plane around a lighting opening for fastening the lamp to the muffle wall, an essentially microwave-proof, translucent metallic shielding sleeve which is galvanically connected to the housing and the connecting flange, and one the interior of the housing from the glass compartment.
- at least one light source in particular an incandescent lamp, associated with each lamp, with the latter being aligned along a central axis, in particular a screw axis, with the lamp holder the lamp-holding metallic housing, a connecting flange connected to the housing and rotating in one plane around a lighting opening for fastening the lamp to the muffle wall,
- Recessed lights for microwave ovens have to meet special requirements. Particularly when using an incandescent lamp as a light source, microwave-tight shielding of the lamp from the cooking space must be ensured.
- a microwave oven with a built-in lamp in which an all-round perfect gal Vanic connection between the shield cover and the muffle wall and thus a perfect microwave tightness is to be achieved in that the shield grille and the glass cover are non-detachably and with good galvanic contact in a metallic socket.
- the socket is screwed into a holder provided with a connecting flange and fastened to the muffle wall.
- This known microwave oven light has a considerable size due to the double socket (inner socket and outer holder) and the screwing direction perpendicular to the installation opening.
- a lighting device for a microwave oven known from DE-C-3 606 421 has a similarly large construction volume.
- the lamp housing is formed from a cylindrical inner sleeve with an internal width of less than the microwave length and an outer sleeve mechanically connected to the inner sleeve and connected to the stove wall. Both sleeves are arranged coaxially on a screw axis running at right angles to the installation opening.
- this lamp housing has a sleeve extension with a narrow diameter, in which at least part of the lamp holder lies. This sleeve extension, which surrounds the entire lamp holder, increases the installation depth of the known lighting device and impairs the standardization of the electrical base connections.
- the invention has for its object to provide a comparatively inexpensive to manufacture and assemble microwave-tight stove recessed luminaire available, in which the position and effectiveness of the shield cover in terms of a microwave-proof closure when changing the light bulb or when cleaning the glass cover are not changed and accordingly the perfect galvanic connection between shielding and the muffle wall and the perfect microwave tightness are always guaranteed.
- the recessed luminaire should enable a compact design and shallow installation depth and be compatible with conventional base connections.
- this object is achieved according to the invention in that the screw axis of the lamp is essentially parallel to the plane of the connecting flange and that the metallic shield cover is firmly installed in the housing, the lamp at least from the lamp base to the filament whose side facing the lighting opening covers and on the side opposite the lamp holder has a suitable large opening for removing the lamp.
- the function of the shield cover as a microwave-proof shielding of a light source, in particular an incandescent lamp, is at least not impaired by large round through openings if this opening is arranged beyond the incandescent filament transversely to the radiation direction of the lamp into the cooking space.
- the preferably approximately cylindrical shield cover can therefore be permanently installed in the interior of the housing.
- a light bulb is inserted and screwed in through the through-opening in the metallic shield cover, which is open in the axial direction.
- the effectiveness of the metallic shield cover and its galvanic connection via the housing to the muffle wall is in no way impaired by removing the glass cover. Even if the glass lid has not been put back on the housing or the muffle wall by mistake, no microwave energy can escape from the cooking space.
- the clear width of the sleeve-shaped peripheral shielding sheath should not exceed the cut-off wavelength of the microwave radiation.
- Optimal microwave tightness can be achieved according to the invention even without a sleeve extension which increases the structural volume of the luminaire when using a conventional luminaire base, in that the shielding envelope consists of a sleeve-shaped metal cage which is open on both sides around the screw axis and a base-side metal flange and that the metal flange with the metal base wall of the housing is joined to form a double-walled structural unit, as a result of which leakage radiation is prevented from escaping through the base wall perforated by the non-metallic base.
- the double-walled unit consisting of the base wall and the edge flange of the shield cover acts similarly to the outer housing extension used in known lighting devices and ensures the necessary microwave tightness despite a base wall opening which is penetrated by the lamp base.
- the elimination of an outer housing extension not only has a favorable effect on a reduction in the overall volume of the stove light, but also enables the use of conventional lamp base connections. In this respect, all electrical components and connections of large-scale range lights can be used in the microwave-tight range light according to the invention.
- the double-walled construction of the housing unit consisting of base wall and flange also enables the position of the screw axis of the lamp to be varied with respect to the level of the connecting flange. Instead of the preferred parallel position of the screw axis to the plane of the connecting flange, an inclination up to an approximation to a rectangular position can be provided, with the short overall depth of the lamp in the direction of Screw axis has a particularly favorable effect.
- the metal flange of the shield cover of the housing base wall surrounding the lamp base is preferably adapted in size and shape in order to expand the double wall in the vicinity of the base opening as far as possible.
- the shielding component according to the invention is characterized in that it consists of a sleeve-shaped metal cage encircling a central axis, open at the end, and an edge flange which adjoins an end and runs approximately radially outwards. With this edge flange, the shielding component according to the invention is placed against the base wall of a stove lamp housing and fixed to the housing, preferably by welding or spot welding. To avoid arcing during microwave operation of the cooker, the surrounding sleeve-shaped metal body in the installed position should have a minimum distance of 1.5 mm, preferably 2.0 mm, from all metal rear and side walls of the housing. The same applies to all other metallic connecting parts which are adjacent to the metal cage or a housing wall in the interior of the housing.
- a particular advantage of the invention lies in the fact that all metal parts which are in galvanic connection for shielding remain in the original installation position when the housing interior is accessed either for maintenance or cleaning purposes.
- the galvanically conductive parts of the luminaire which are made of corrosion-resistant metal for safety reasons, can be made small and can be designed to be inexpensive and functional as stationary parts. Due to the preferred position of the screw axis of the lamp pa parallel to the muffle wall, in which the lighting opening is formed, the installation depth is comparatively small, so that the new lamp is particularly suitable for incorporation into a side muffle wall of the cooking space.
- the basic size, design and base design of the new microwave oven light can correspond to that of a normal built-in oven light with conventional thermal heating elements.
- the metallic shield cover has reliable shielding with only a slight loss of light if it consists of perforated metal sheet or wire with opening cross sections of at most 5 mm.
- the housing can be trough-shaped and, in the area of the lighting opening, be delimited in the form of a frame by an integral connecting flange.
- the metallic housing is preferably provided with reflective surfaces on its inside facing the lamp.
- a preferred embodiment of the stove light is characterized in that the connecting flange can be connected to a frame-shaped metallic fastening flange and that the fastening flange is perpendicular to the flange plane on one side has projecting fixed bolts which are arranged in a predetermined grid and can be pushed through holes arranged in corresponding grids in the muffle wall and the connecting flange.
- the distance between the adjacent bolts should be sealed for microwave reasons unit 40 mm, preferably not exceed 30 mm.
- the housing, the metallic shield cover, the connecting flange and the mounting flange are usually made of corrosion-resistant metal, e.g. Stainless steel.
- the glass cover should be locked in a manner known from conventional oven lights (DE-A 3 428 329) with suitable spring elements of the housing itself.
- the invention is further developed in that rib-shaped holding members are formed with undercuts on the side of the glass cover facing the interior of the housing, which cooperate with locking springs attached to the housing in such a way that the locking springs positively engage in the undercuts of the glass cover.
- a double glass cover with a cavity enclosed between the two glass panes is particularly suitable for use in stoves with pyrolytic cleaning capability.
- the cover which consists of glass panes, cavity, frame and possibly all-round seal, forms thermal insulation to protect the temperature-sensitive light bulb against the high temperatures during pyrolytic cleaning.
- the microwave oven light 1 according to the exploded view in FIG. 1 has a metal housing 2 with a base 3 held in the housing, a base socket, a screwed-in incandescent lamp 4, a hollow cylindrical metal cage 5, which forms the shielding cover, and a connecting flange 7 surrounding a lighting opening 6, which is integrally connected to the rest of the housing 2. Furthermore, a mounting flange 10 and a plate-shaped glass cover 11 are shown in FIG.
- the trough-shaped housing 2 is welded to avoid microwave-permeable gaps at the joints or connecting points of adjacent metal sections and therefore forms a microwave-tight hood that largely covers the outside of the lighting opening 6.
- the area of the socket of the incandescent lamp 4 and the exit of the electrical line connections through the base 3 are critical. This area must be made microwave-tight in the exemplary embodiment described and in the prior art.
- the through opening 9 is as wide as the inside diameter of the hollow cylindrical metal cage 5 (FIG. 3). It is arranged on the end face of the shield cover 5 opposite the base 3.
- the bulb 4 is behind Removing the glass cover 11 accessible and can be unscrewed from its socket in the base 3 in the direction of a screw axis 13.
- the metal cage 5 serving as a shield cover is fixedly mounted on the housing 2, preferably welded.
- the housing surfaces facing the interior of the housing are designed to be reflective, so that the highest possible luminous efficiency can be used for illuminating the cooking space.
- connection flange 7 is placed directly on the edge of the muffle opening when installing the lights.
- the attachment to the muffle edge takes place with the aid of a mounting flange 10.
- the mounting flange 10 carries screw bolts 14 on one side.
- the screw bolts are arranged in a grid in which the center distance between adjacent bolts is as uniform as possible approximately between 25 and 29 mm. (Only the distance between the bolts flanking the base 3 in the installed position is sufficiently large that the latter can be easily countered next to the base 3 by means of nuts not shown in the drawing).
- the fastening flange 10 has an opening 16 corresponding to the lighting opening 6 in terms of size and shape.
- holes 17 are formed in the connecting flange 7 and in the muffle wall, which are adapted to the diameter of the bolts 14. Between the side of the mounting flange 10 carrying the bolts 14 and the muffle rim surrounding the installation opening, a closed seal with a metallic surface is regularly installed, which ensures the galvanic connection between the mounting flange 10 and the muffle wall or the connecting flange 7.
- rib-shaped holding members 21 are formed, into which grooves 22 which are open to the outside are incorporated.
- suitable catch springs 23 (FIG. 11) engage in the grooves, which firmly press the glass cover 11 with its inner edge 20 from the cooking chamber onto the adjacent surface of the fastening flange 10.
- the open openings 8 (in the jacket of the metal cage 5) should not exceed a certain cross section, so that the function of the microwave-tight closure of the lamp 4 and its holder does not impair the shielding cover 5.
- slit-like light passage openings should be avoided.
- the openings 8 can and should be made as large and dense as possible in the interest of good light output and better heat dissipation.
- the metal cage can also be designed as a latticework.
- FIGS. 6 to 8 show a special shielding component 50 which can also be used as a shield cover 5 for the luminaire 1 as shown in FIGS. 1 to 3.
- the component 50 has a sleeve-shaped metal cage 51 with open openings 8 for the passage of light.
- the metal cage can be made from a rectangular, perforated sheet metal blank that is curved around a central axis 13 and welded along an overlap edge that is parallel to the axis.
- a metal flange 52 is connected under galvanic contact. The galvanic contact is produced by welding a sleeve-shaped section 53 to the section near the edge of the corresponding sleeve-shaped metal cage 51.
- Metal cage 51 and metal flange 52 can, however, also be produced as a one-piece molded metal part, for example using the deep-drawing process.
- Angled Connection tabs 54 are formed on opposite parallel outer edges of the metal flange 52.
- the connection tabs 54 are used for the galvanic connection of the shielding component 50 to the housing of the stove light, as will be explained further below.
- the cross-sectional shape of both the metal cage 51 and the outline shape of the flange 52 can be adapted to the space and space available in the interior of the stove light.
- the circular through opening 9 of the metal cage 51 here can be oval or rectangular. The same applies to the approximately rectangular outline shape of the flange 52 shown in the exemplary embodiment.
- FIGS. 9 and 10 show an installation example of the shielding component 50, shown enlarged in FIGS. 6 to 8, in a stove light 1 a, which is otherwise similar to that of the first exemplary embodiment.
- the flange 52 of the component 50 lies against a base wall 30 of the housing 2 holding the base 3.
- the metal flange 52 and base wall 30 are welded to one another at spot welds.
- the connecting tabs 54 are welded to side walls 31 of the housing 2. In this way, the metal flange 52 is joined to the metallic base wall 30 of the housing 2 to form a double-walled structural unit.
- the clear width of the metal cage 51 which is open on both end faces should be smaller than the minimum wavelength of the high-frequency waves used. As can be seen, there is no need for a shielding extension due to the double-walled design of unit 30/52, so that the base connections can be freely accessible as with normal stove light connections.
- Figure 9 shows the preferred parallel position of the screw axis 13 to the connection plane of the lamp 1a in the muffle wall, not shown. At least smaller angles of attack between 20 and 800, for example, are easily possible, depending on requirements.
- a minimum distance a of 1.5 mm should remain between the outer circumference of the metal cage 51 and the inside of the bottom wall 32 of the housing 2 in order to avoid arcing in microwave operation.
- FIGS. 12 to 14 show different embodiments 11a, 11b and 11c of double glass covers, each of which can be used instead of the one-piece glass cover 11 (FIG. 1) in conjunction with the detent springs 23 (FIG. 11) especially for stoves with pyrolytic cleaning options.
- These double glass covers enable the use of incandescent lamps in the stove lamp described at the high temperatures typical for pyrolytic cleaning. There are currently no incandescent lamps that can be used at temperatures above 300 ° C. Due to a cavity 40a, 40b and 40c formed between the two glass panes, the temperature reduction between the interior of the oven and the interior of the lamp required for the use of incandescent lamps in the microwave-tight oven light can be achieved.
- two flat glass panes 41a are kept at a distance via a temperature-resistant seal 42a.
- the sandwich component consisting of the two flat glass panes and the seal is kept at a distance by a metal surround 43.
- the metal surround has molded metal catches 44, which interact with complementary catches on the housing.
- two oppositely curved pressing glasses 41b lie together and are possibly glued together along the peripheral edge.
- a heat-resistant seal 42b is provided on one side of the double glass pane.
- the temperatures between the cooking space and the interior of the luminaire can be reduced even further by providing at least one of the glasses 41a, 41b, 41c with a thin, partially reflecting coating, for example by vacuum vapor deposition.
- the coating is preferably deposited on the glass side facing the cavity 40a, 40b, 40c.
- a pressed glass pane 41c is assigned to a flat glass pane 41a.
- the two disks are kept at a distance by a temperature-resistant seal 42c.
- a partially circular or oval housing cross section can be provided.
- the shielding component 50 can be box-shaped.
- the stove light according to the invention can be used in an analog design and with the same advantages in connection with other light sources, for example with halogen lamps, and with corresponding sockets and bases, for example with plug-in, pin or bayonet bases.
- the galvanic connections can also be made by soldering, riveting or screwing.
- a suitably conductive metal ceramic can also be used under certain circumstances.
- different combinations of individual features of the subclaims with one another are possible.
