Definitions

  • the invention relates to a cooking appliance light for cooking appliances with microwave cooking function, in particular for so-called combination cooking appliances.
  • Combination cooking appliances with a microwave function allow food to be prepared not only using microwave energy but also in other ways, such as baking or steaming.
  • Combination appliances are therefore available as combined oven-microwave cooking appliances or as combination appliances that include both an oven and microwave function and a steaming function.
  • Ovens are also known that can increase the humidity in the cooking chamber by adding small amounts of steam to support certain baking and cooking functions.
  • a grid-like microwave trap as a blocking element in front of a lighting device of a microwave cooking appliance is US 4,367,388 A revealed.
  • DE 29 37 499 B discloses a cooking appliance light for microwave ovens.
  • a mounting sleeve is located in a cutout in the oven wall. This mounting sleeve is provided with an internal thread.
  • the light consists of a metal sleeve with a translucent cover and a locking element located behind the cover. The metal sleeve has an external thread that engages the internal thread of the mounting sleeve to hold the light to the cooking chamber wall.
  • US 7,267,450 B2 shows a generic cooking appliance light in which a pot-shaped housing holding the light source is inserted into the opening of a cooking chamber wall.
  • a translucent cover which is provided with a locking element on the inside, is snapped into the pot-shaped housing.
  • the DE 36 06 421 C1 shows that a sleeve surrounding the lamp of the luminaire can be perforated in a sieve-like manner so that it serves as a barrier element for microwave radiation.
  • LED light sources have the primary advantage of consuming significantly less power, thus positively impacting and reducing the overall energy consumption of a cooking appliance. Furthermore, they are compact, allowing for a smaller installation space. Overall, LED light sources open up new possibilities in the design of cooking appliances.
  • the smaller form factor of LED light sources also allows for a significant reduction in the number of openings in the cooking chamber wall required to introduce the light illuminating the cooking chamber, which also helps prevent heat loss and thus reduce the energy consumption of cooking appliances. Since the energy efficiency of cooking appliances is a key marketing argument, these factors are of considerable importance for economic success.
  • the object of the invention is to provide a cooking appliance light for cooking appliances with microwave cooking function, which can be installed in wall cutouts for conventional light sources and still meets the requirements of LED light sources.
  • the invention is solved by a cooking appliance light with the features of claim 1.
  • the invention faces the problem that the snap-in wings protruding from the peripheral wall result in openings in the peripheral wall of the mounting sleeve.
  • Such peripheral wall openings pose the risk of microwave radiation escaping instead of being properly absorbed.
  • the invention therefore provides that the mounting sleeve is provided with an inner sleeve which covers the openings in the peripheral wall of the mounting sleeve caused by the deployment of the locking wings.
  • the additional effort required for pre-assembling the cooking appliance light is more than offset by the simple snap-in installation at the cooking appliance manufacturer, so that this effort is justified in every respect.
  • the locking tabs are provided with a free locking end pointing towards the translucent cover and a Have a connection end facing away from the cover, with which they are held to the inner sleeve peripheral wall.
  • the absorption of the microwave radiation when the inner sleeve is locked into the outer sleeve is ensured by the fact that the locking tabs of the inner sleeve and the locking wings of the outer sleeve are arranged circumferentially offset from one another in order to avoid alignment of the circumferential wall openings of the inner sleeve and the mounting sleeve.
  • the mounting stop is formed by the end of the inner sleeve closest to the LED light source. This eliminates the need to machine the mounting sleeve to create a mounting stop for holding the locking element between the LED holder and the mounting stop.
  • centering springs engage around the inner sleeve circumferential wall.
  • the inner sleeve form a retaining flange at its end closest to the translucent cover, which rests on or overlaps the mounting flange. This ensures that there is no open annular gap between the mounting sleeve and the inner sleeve on the cooking chamber side through which microwave radiation could penetrate to the outside.
  • An electrical connection between the locking element and the cooking chamber wall can also be established if the mounting sleeve provides a mounting stop for the locking element and the holding part holds the locking element to the mounting stop.
  • the first embodiment is shown in the Figures 1 to 6
  • This is a cooking appliance light, designated overall by reference number 100, which is intended for use in a microwave cooking appliance, particularly in a combination cooking appliance with a microwave cooking function.
  • the cooking appliance itself is not shown.
  • Fig. 1a first shows the essential components of the cooking appliance light 100.
  • the central component of the cooking appliance light 100 is a mounting sleeve 101.
  • This has a mounting flange 102 which is provided with through holes 103.
  • the mounting sleeve 101 serves to anchor the cooking appliance light 100 in the cutout of a cooking chamber wall.
  • the mounting flange 102 rests on the inside of the cooking chamber wall.
  • the through-holes 103 align with threaded holes and, if applicable, threaded bosses on the cooking chamber wall. Screw bolts (not shown) penetrate the through-hole 103 to reach the threads on the cooking chamber wall and hold the mounting sleeve 101, and with it the cooking appliance light 100, to the cooking chamber wall.
  • the sleeve interior 104 of the mounting sleeve 101 is closed on the cooking chamber wall side by a cover glass 105.
  • a ring element 106 is arranged between the mounting flange 102 and the cover glass 105. This ring element has a sealing effect and can also apply a longitudinal axial preload to the sleeve to secure the cover glass 105 screwed into the mounting sleeve 101 against unintentional unscrewing.
  • the cover glass 105 For screw fastening of the cover glass 105 in the mounting sleeve 101, the cover glass 105 has a threaded neck 108 provided with an external thread 107.
  • the external thread 107 engages in thread sections 109 which are embossed into the peripheral wall 110 of the mounting sleeve 101.
  • the mounting sleeve 101 then forms retaining tabs 111 at its end facing away from the cover glass 105 or the mounting flange 102.
  • the retaining tabs 111 are directed longitudinally axially and are set with their free ends pointing radially inward.
  • the illuminant 112 of the cooking appliance light 100 is an LED light source, which is designed in the form of a circuit board 113 that carries an unspecified LED and is also provided with terminals 114 for connecting connecting conductors 115.
  • the connecting conductors 115 are primarily used to supply power to the LED, but can also be used to transmit control signals if required.
  • the circuit board 113 is mounted on a counter-support 116, here in the form of a heat sink.
  • the heat sink 116 serves to dissipate the waste heat generated during operation of the LED.
  • Pins 117 are provided to secure the circuit board 113 to the heat sink 116.
  • a holding part 118 receives the heat sink 116 with the printed circuit board 113 arranged thereon via a holding arm 119 at its end facing away from the mounting sleeve 101.
  • the heat sink 116 is preferably latched to the holding arms 119. Additionally, it can be secured to the holding part 118 via a securing element 120, for example in the form of a screw.
  • the holding part 118 also carries an optical element 121, for example a lens, which is arranged in the beam path of the light-emitting LED of the circuit board 113 and directs the emitted light into the cooking chamber for optimal light feed.
  • the optical element 121 is arranged in a holding ring 122. This holding ring 122 ensures the correct distance between the optical element 121 and the LED.
  • the holding ring 122 can also serve as a reflector to guide scattered light emitted by the LED to the optical element 121 and thus make it usable for illuminating the cooking chamber.
  • the holding part 118 is furthermore formed by a plurality of annular discs 123 spaced apart along the sleeve's length. These annular discs 123 each form a heat shield to dampen the radiant heat that acts from the cooking chamber through the mounting sleeve 101 in the direction of the light source 112.
  • the radial Gaps 124 between the annular disks 123 allow an air flow to pass through, which serves to dissipate heat and thus to cool and protect the LED light source 112.
  • the cooking appliance light 100 comprises a microwave trap in the form of a grid-like blocking element 125.
  • This is designed in the form of a substantially circular, perforated disc.
  • Centering means 126 in the form of axially directed spring ribs, which extend slightly radially outward, extend from the disc's edges. These are supported on the inner circumference of the peripheral wall 110 during installation of the blocking element 125 in the mounting sleeve 101 and center the blocking element 125 within the mounting sleeve 101.
  • the holding part 118 forms plug-in receptacles 127 which are provided for receiving the holding tabs 111, wherein each plug-in receptacle 127 can have a locking lug 128 which engages in a locking opening (not shown) of the holding tab 111.
  • FIG. 1b The perspective view according to Fig. 1b shows the cooking appliance light 100 just described in assembled form.
  • cover glass 105 is attached to the mounting sleeve 101.
  • the ring element 106 is arranged between the cover glass 105 and the mounting flange 102.
  • the holding part 118 carries, on its side facing away from the cover glass 105, the heat sink 116 provided with the printed circuit board 113 with its holding arms 119.
  • the retaining tabs 111 are seated in the plug-in receptacle 127 of the retaining part 118 and thus fix the retaining part 118 to the mounting sleeve 101.
  • the pre-assembled cooking appliance light 100 can then be finally installed in the cooking appliance by the cooking appliance manufacturer.
  • Fig. 2 shows a top view of the cooking appliance light 100, with the cover glass 105 hidden. Therefore, the annular blocking element 125 in the form of a perforated disc can be seen, as it is arranged centered in the sleeve interior 104. It is also visible that the centering ensures that the fit clearance required for assembly in the form of circumferential gap sections 129 is approximately uniform all around. The distance caused by each circumferential gap section 129 between the circumferential wall 110 of the mounting sleeve 101 and the blocking element 125 is not greater in its radial depth than the diameter of the perforation holes of the blocking element 125. This ensures that no microwave radiation can penetrate outward through the mounting sleeve 101 in the axial direction.
  • Fig. 3 shows another side view of the cooking appliance light 100. This shows once again how the threaded sections 109 are embossed into the peripheral wall 110 of the mounting sleeve 101. It is also visible that the retaining tabs 111 of the mounting sleeve 101 are seated in the plug-in receptacles 127 of the holding part 118.
  • Fig. 4 shows a sectional view of the cooking appliance light 100 along the section line IV-IV in Fig. 3 .
  • This illustration initially shows the interaction of the threaded sections 109 on the side of the mounting sleeve 101 and the external thread 107 of the cover glass 105.
  • special attention should be paid here to the locking element 125.
  • the locking element 125 sits on the holding part 118 in such a way that the centering means 126 also serve to hold the locking element 125 on the holding part 118, preferably to snap it onto it.
  • the locking element 125 resting on the holding part 118 can thus be secured to the mounting sleeve 101 together with the holding part 118.
  • the holding part 118 with its end section near the cover glass 105, extends at least minimally into the sleeve interior 104.
  • the locking element 125 is inserted into the sleeve interior 104 strictly horizontally or transversely to the sleeve's longitudinal axis, thus ensuring a correct mounting position.
  • the heat sink 116 is secured in the holding part 118 by the securing element 120.
  • the holding part 118 forms a securing dome 130 that extends in the opposite direction to the cover glass 105.
  • the heat sink 116 is engaged behind by a locking projection 131 of a holding arm 119.
  • Fig. 5 shows another side view of the cooking appliance light 100. This is different from the illustration according to Fig. 3 rotated by about 90 degrees.
  • FIGS. 5 and 6 show the Figures 3 and 4 the facts already described from a correspondingly changed perspective.

This is largely identical to the first embodiment and there the Figure 4 , as far as the components below the mounting sleeve 201, i.e. the components arranged at the end of the mounting sleeve 201 remote from the cover glass, are concerned. In this respect, reference is made to the Figure 4 said.
  • the interaction of the mounting sleeve 201 and the inner sleeve 238 is once again clearly visible. It can be seen that the inner sleeve 238 is located in the interior space 204 of the mounting sleeve 201 and is held concentrically.
  • the support flange 240 covers the mounting flange 202 and thus covers the annular space 244 necessarily present between the mounting sleeve 201 and the inner sleeve 238 from the cooking chamber (not shown). Penetration of microwave radiation into this annular space 244 and thus a possible axial passage of microwave radiation into the outside environment is thus reliably prevented.
  • the inner sleeve 238 locks into the mounting sleeve 201. This considerably simplifies the arrangement of the inner sleeve 238 in the mounting sleeve 201.
  • the locking tabs 241 described above serve this purpose.
  • the locking tabs 241 projecting from the sleeve wall 239, also introduce openings into the sleeve wall 239, the special arrangement of the locking tabs 241 with their connected end far from the cover glass and the end protruding close to the cover glass 205 was initially chosen. In this way, incident microwave radiation is reflected back toward the cooking chamber or absorbed by an electrical conductor. If microwave radiation escapes through the openings in the sleeve wall 239, it can at most enter the annular space 244 and is absorbed there upon impact with the mounting sleeve 201.
  • the openings in the sleeve wall 239 are always arranged sufficiently offset from the openings in the peripheral wall 210 of the mounting sleeve 201.
  • Figure 12 now shows a second side view of the cooking appliance light 200.
  • the counterpart to Figure 12 is the Figure 5 to the first embodiment.
  • Figure 5 is the Figure 5 to the first embodiment.
  • Figure 5 is the Figure 5 to the first embodiment.
  • Figure 5 is the Figure 5 to the first embodiment.
  • Figure 5 is the Figure 5 to the first embodiment.
  • Figure 13 shows a sectional view according to section line XIII in Figure 12 .
  • the counterpart to Figure 13 is the Figure 6 of the first embodiment. Unless specific components of the cooking appliance light 200 according to the second embodiment are shown, the Figure 6 executed.
  • the locking element 225 of the cooking appliance light 200 is seated at the end of the inner sleeve 238 remote from the cover glass, which thus represents an assembly stop for the locking element 225.
  • the locking element 225 is mounted between the end of the inner sleeve 238 remote from the cover glass 205 and the end of the holding part 218 near the cover glass 205.
  • the centering means 226 are not supported on the inner circumference of the sleeve wall 239 or the peripheral wall 210. Instead, the centering means 226 rest on the outer circumference of the sleeve wall 239 of the inner sleeve 238. They hold the locking element 225 there at least frictionally; a positive fit is certainly conceivable.
  • the cooking appliance light 100 it was proposed that the locking element 125 on the holding part 118
  • the inner sleeve 238 together with the locking element 225 is inserted into the mounting sleeve 201.
  • the holding part 218 is placed in the opposite direction, from the side remote from the cover glass 205, onto the end of the mounting sleeve 201 remote from the cover glass 205, so that in this way the locking element 225 is securely arranged between the holding part 218 and the inner sleeve 238.
  • the second embodiment can dispense with an inner sleeve 238 if the wall gaps created by the deployment of the locking wings 236 are kept narrow enough. The escape of microwave radiation can then be reliably prevented even without an inner sleeve 238.
  • the fixing of the holding part 218 and the blocking element 225, as well as the cover glass 205, is then carried out analogously to the first embodiment.
  • Cooking appliance manufacturers can use the lights 100, 200 for microwave cooking appliances or combination cooking appliances with a microwave cooking function, as an effective blocking element and a clever lamp design reliably prevent microwave radiation from escaping from the cooking chamber.
  • the support flange 240 of the inner sleeve 238 also contributes to this. In this case, a secure and centered mounting of the blocking element 125, 225 in the cooking appliance light 100, 200 is guaranteed in every case.
  • the cooking appliance light 100, 200 is designed for installation in cooking chamber wall cutouts for conventional light sources, but uses an LED light source 112, 212.
  • the cooking appliance lights 100, 200 adapt existing component structures to modern LED light sources.
  • Advantageous fastening techniques are used to anchor the cooking appliance light 100, 200, which were previously only used for cooking appliance lights with conventional light sources 112, 212.
  • both embodiments of the cooking appliance lights 100, 200 also manage to meet the requirements of LED lamps, in particular to reliably protect them from the potentially harmful heat radiation of the cooking chamber.
  • the LED lamp 112, 212 is arranged outside the mounting sleeve 201, in particular at the end thereof remote from the cover glass 105, 205. This not only distances the LED lamp 112, 212 from the cooking chamber. It also mounts the LED lamp 112, 212 outside the sleeve body, in which heat buildup can occur in case of doubt.
  • the use of a holding part 118, 218 enables the lamps 112, 212 to be mounted outside the mounting sleeve 201.
  • the applicant uses a special holding part which, in addition to the advantageous arrangement of the illuminants 112, 212 outside the mounting sleeve 201, also ensures advantageous ventilation through gaps 224, 124 and protection against heat radiation via annular discs 123, 223.
