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 cooking function allow food to be prepared in other ways in addition to using microwave energy, for example by baking or steaming.
  • Combination appliances are therefore available as combined oven-microwave cooking appliances or as combination appliances that include a steam cooking function in addition to the oven function and the microwave cooking function.
  • a grid-like microwave trap as a blocking element in front of a lighting device of a microwave cooking appliance is US$4,367,488 disclosed.
  • LED lighting sources have the main advantage that they consume significantly less power and thus have a positive effect on the overall energy consumption of a cooking appliance, i.e. reduce it. They are also small in size, meaning that the space required for the lighting can be reduced. Overall, LED lighting sources open up new possibilities in the design of cooking appliances.
  • the smaller form factor of LED lamps also allows the number of openings in the cooking chamber wall to be significantly reduced to introduce the light that illuminates the cooking chamber, which also helps to avoid heat loss and thus reduce the energy requirements 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 used in wall cutouts for conventional lamps and yet meets the requirements of LED lamps.
  • the invention is solved by a cooking appliance lamp with the features of claim 1.
  • the mounting sleeve can have a closed sleeve wall and a mounting flange at its axial end near the cover.
  • the closed sleeve wall has the advantage of safely diverting incoming microwave radiation. Since the sleeve wall is closed, i.e. without any holes, no microwave radiation can leave the mounting sleeve in the radial direction.
  • the mounting flange is designed for screw fastening to the cooking chamber wall and has through holes for screw bolts.
  • the fastening is designed to be electrically conductive so that an electrical connection is established between the mounting flange and the cooking chamber wall, particularly via the screw bolts.
  • the through holes in the mounting flange are at least partially bare.
  • at least the threads on the cooking chamber wall side are bare so that the screw bolts establish the electrical connection between the mounting flange and the cooking chamber wall.
  • the mounting sleeve can be provided with locking wings protruding from its peripheral wall for locking onto the cooking chamber wall. In this way, the cooking appliance light can be firmly anchored to the cooking chamber wall by simply inserting it into the recess in the cooking chamber wall.
  • an LED light source arranged on the mounting sleeve combines the advantages of the mounting sleeve with the use of a modern light source, in particular when the LED light source is mounted on a holding part, the holding part is arranged on the axial end of the mounting sleeve facing away from the cover, and the LED light source is arranged upstream of the axial end of the mounting sleeve facing away from the cover in the light feed direction.
  • the LED light source is sufficiently far and safely spaced from the cooking chamber and is therefore only exposed to the cooking temperatures to a technically acceptable extent. This ensures a long service life of the LED light source. It also allows a cooling air flow to be passed past the LED light source without any problems, so that ventilation of the sleeve is not necessary.
  • Such sleeve ventilation which would be necessary for an LED arranged inside the sleeve, can only be provided with great effort, since the necessary ventilation openings would have to be suitably closed to prevent the escape of microwave radiation.
  • the locking element within the mounting sleeve and to connect it to the mounting sleeve in an electrically conductive manner so that the Microwave radiation is absorbed via the electrical connection with the mounting sleeve and the cooking chamber wall.
  • the mounting sleeve provides a mounting stop for the locking element and the holding part holds the locking element on the mounting stop.
  • This design has significant manufacturing advantages, since the locking element is ultimately held in a clamped manner between the holding part of the LED lamp and the mounting stop and does not have to be attached separately.
  • the locking element In order to ensure that the locking element is positioned correctly within the mounting sleeve, it is recommended that the locking element has centering means that align the locking element centrally within the mounting sleeve.
  • the centering of the locking element ensures that the unavoidable manufacturing tolerances as well as the clearance required for inserting the locking element into the mounting sleeve do not lead to gaps between the locking element and the mounting sleeve that prevent absorption of the microwave radiation by the locking element and the mounting sleeve.
  • the centering means establish an electrically conductive connection between the locking element and the mounting sleeve.
  • centering means are designed as centering springs arranged on the outside of the locking element and integrally connected to the locking element.
  • a further assembly advantage can be achieved if the holding part of the LED light source preferably has the locking element snapped on.
  • the locking element and the holding part of the LED light source form a pre-assembled unit that can be easily inserted into the mounting sleeve or easily attached to the mounting sleeve.
  • a secure electrically conductive connection between the mounting sleeve and the cooking chamber wall is ensured if the mounting sleeve has a plug connection for connecting an electrical conductor for an electrical connection to a cooking chamber wall.
  • the mounting sleeve forms thread sections into which mating threads of the cover engage for releasable fastening. In this way, the cover can be easily secured to the mounting sleeve.
  • the invention faces the problem that the snap-on wings protruding from the peripheral wall result in openings in the peripheral wall of the mounting sleeve.
  • Such peripheral wall openings pose the risk that microwave radiation will escape here 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 locking tabs are provided with a free locking end pointing towards the translucent cover and a connection end facing away from the cover, with which they are held to the inner sleeve peripheral wall.
  • the absorption of microwave radiation when the inner sleeve is locked into the outer sleeve is ensured by the locking tabs of the inner sleeve and the locking wings of the outer sleeve being 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 shape the mounting sleeve to create a mounting stop to hold the locking element between the LED holder and the mounting stop.
  • centering springs engage around the inner sleeve peripheral wall.
  • the inner sleeve forms a retaining flange at its end closest to the translucent cover, which rests on the mounting flange or overlaps it. 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 on the mounting stop.
  • the first embodiment is in the Figures 1 to 6
  • This is a cooking appliance lamp, designated overall with the reference number 100, which is intended for use in a microwave cooking appliance, in particular in a combination cooking appliance with a microwave cooking function.
  • the cooking appliance itself is not shown.
  • Fig. 1a first shows the essential individual parts 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 are aligned with threaded holes and, if necessary, threaded domes on the cooking chamber wall. Screw bolts (not shown) pass through the through hole 103 to reach the thread on the cooking chamber wall side and hold the mounting sleeve 101 and with it the cooking appliance light 100 as a whole 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 has a sealing effect and can also apply a longitudinal axial preload to the sleeve in order to fix 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 aligned longitudinally axially and are set with their free ends pointing radially inwards.
  • the lighting means 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 connection terminals 114 for connecting connecting conductors 115.
  • the connecting conductors 115 primarily serve to supply voltage to the LED, but can also be provided for transmitting control signals if required.
  • the circuit board 113 is mounted on a counter bearing 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.
  • Plug-in bolts 117 are provided for fastening the circuit board 113 to the heat sink 116.
  • a holding part 118 receives the heat sink 116 with the 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 locked onto the holding arms 119.
  • 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 in order to ensure optimum 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 can 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 lighting the cooking chamber.
  • the holding part 118 is also formed by several ring disks 123 spaced apart along the length of the sleeve. These ring disks 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. In addition, the radial gaps 124 between the ring 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 disk that is perforated.
  • Centering means 126 in the form of axially directed spring ribs that are slightly radially outwardly protrude from the edges of the disk.
  • 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 in a securing manner.
  • FIG. 1b The perspective view according to Fig. 1b shows the cooking appliance light 100 just described in assembled form. Here you can clearly see how the 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 circuit board 113 with its holding arms 119.
  • the retaining tabs 111 are seated in the plug-in receptacle 127 of the holding part 118 and thus fix the holding 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 view from above of the cooking appliance light 100, with the cover glass 105 hidden.
  • the ring-shaped blocking element 125 in the form of a perforated disk can therefore be seen, as it is arranged centered in the interior of the sleeve 104. It is also visible that the centering ensures that the clearance required for assembly in the form of circumferential gap sections 129 is approximately the same 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. It is thus ensured that no microwave radiation can penetrate through the mounting sleeve 101 to the outside in the axial direction.
  • Fig.3 shows another side view of the cooking appliance light 100. This shows once again how the thread 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 thread sections 109 on the side of the mounting sleeve 101 and the external thread 107 of the cover glass 105.
  • special attention must 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 into place there.
  • This has assembly advantages.
  • the locking element 125 sitting on the holding part 118 can thus be secured to the mounting sleeve 101 together with the holding part 118.
  • the holding part 118 dips at least minimally into the sleeve interior 104 with its end section near the cover glass 105.
  • the locking element 125 is introduced into the sleeve interior 104 strictly horizontally or transversely to the sleeve longitudinal axis, so that a correct mounting position is ensured.
  • the holding part 118 forms a securing dome 130 for this purpose, which extends in the opposite direction to the cover glass 105. It is also visible how the heat sink 116 is engaged behind by a locking projection 131 of a holding arm 119.
  • the optical element 121 sits in the retaining ring 122 and how the retaining ring 122 arranges the optical element 121 at the correct distance from the circuit board 113 or the light source 112. It can also be clearly seen from this illustration that, if the inner surfaces 132 are appropriately mirrored, the retaining ring 122 can serve as a reflector.
  • 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.

  • Figure 8 shows, however, in contrast to the first embodiment, on the one hand that the aforementioned flat plug 235, which in this embodiment is electrically connected to the locking element 225, is led out of the mounting sleeve 201 away from the cover glass in order to be able to attach an electrical conductor.
  • Figure 8 also shows how the mounting sleeve 201 and the inner sleeve 238 interact with respect to the locking wings 236.

  • the inner sleeve 238 is arranged in the mounting sleeve 201 in such a way that it covers these openings 242. Consequently, microwaves penetrating through the cover glass 205 cannot escape through the openings 242.
  • Figure 9 the second embodiment is the analog representation to Figure 2 the first embodiment.
  • a view from above of the cooking appliance light 200 is shown, whereby essentially identical facts apply to the Figure 2 or the first embodiment.
  • the locking element 225 arranged in the inner sleeve space 243 in the form of a disk perforated by a plurality of holes can be seen.
  • the support flange 240 of the inner sleeve 238 can be seen in particular, which covers the mounting flange 202 of the mounting sleeve 201.
  • the function of the centering means 226, which hold the locking element 225 centered in the inner sleeve space 243 can also be seen here.
  • the side view of the cooking appliance light 200 of the second embodiment in Figure 10 has its counterpart in Figure 3 the first embodiment.
  • the locking effect of the locking lug 228 in the plug receptacle 227 for securing the holding arm 229 is also clearly visible here.
  • FIG 11 shows a sectional view according to section line XI in Figure 10 .
  • This shows the basic structure of the cooking appliance light 200 in assembled form. This is largely identical to the first embodiment and the Figure 4 , as far as the components below the mounting sleeve 201, i.e. the As regards the components arranged at the end of the mounting sleeve 201 remote from the cover glass, reference is made to the Figure 4 said referred to.
  • the locking tabs 241 which protrude from the sleeve wall 239, also create openings in the sleeve wall 239, the special arrangement of the locking tabs 241 with their end connected to the cover glass far away and the end protruding close to the cover glass 205 was initially chosen. In this way, incident microwave radiation is reflected back in the direction of the cooking chamber or absorbed by an electrical discharge. 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 when it hits the mounting sleeve 201.
  • the openings in the sleeve wall 239 are in any case 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 lamp 200 according to the second embodiment are shown, the Figure 6 executed.
  • the locking element 225 of the cooking appliance light 200 is located on the end of the inner sleeve 238 which is remote from the cover glass, which thus represents an assembly end stop for the locking element 225.
  • the locking element 225 is mounted between the end of the inner sleeve 238 which is remote from the cover glass 205 and the end of the holding part 218 which is close to the cover glass 205.
  • the centering means 226 are not supported on the inside circumference of the sleeve wall 239 or the peripheral wall 210. Instead, the centering means 226 sit on the outside 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 While it was proposed for the first embodiment, the cooking appliance light 100, that the locking element 125 be pre-assembled on the holding part 118, it is proposed for the cooking appliance light 200 according to the second embodiment that the locking element 225 be pre-assembled on the inner sleeve 238.
  • 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 safely 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 then takes place analogously to the first embodiment.
  • the cooking appliance manufacturers can use the lights 100, 200 for microwave cooking appliances or combination cooking appliances with the microwave cooking function, since an effective blocking element and a clever lamp construction reliably prevents 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 locking element 125, 225 in the cooking appliance lamp 100, 200 is guaranteed in every case.
  • the cooking appliance light 100, 200 is designed for installation in cooking chamber wall cutouts for conventional lamps, but uses an LED lamp 112, 212 itself.
  • the cooking appliance lights 100, 200 adapt existing component structures to modern LED lamps.
  • Advantageous fastening techniques are used to anchor the cooking appliance light 100, 200, which have previously only been used for cooking appliance lights with conventional lamps 112, 212.
  • both embodiments of the cooking appliance lights 100, 200 also manage to meet the requirements of LED lamps, in particular to protect them safely from the potentially harmful heat radiation of the cooking chamber.
  • the LED lamp 112, 2012 is arranged outside the mounting sleeve 201, in particular at the end remote from the cover glass 105, 205. This not only distances the LED lamp 112, 212 from the cooking chamber. It also stores the LED lamp 112, 212 outside the sleeve body, in which heat can build up in case of doubt.
  • the use of a holding part 118, 218 enables the lamps 112, 212 to be stored outside the mounting sleeve 201.
  • the applicant uses a special holding part which, in addition to the advantageous arrangement of the lamps 112, 212 outside the mounting sleeve 201, also provides advantageous ventilation through Gaps 224, 124 and protection against heat radiation via ring disks 123, 223 are ensured.
