Description

Technical Field

[0001] The invention relates to a cooking appliance lamp, in particular an oven lamp, comprising a lamp glass on its upper side and a lamp base on its lower side, wherein a geometric longitudinal center axis is arranged vertically through the lamp base, the cooking appliance lamp comprising:

[0002] - has a neck on the underside of the luminaire glass, said neck carrying at least one groove arrangement consisting of an axially extending vertical groove and a horizontal groove adjoining said vertical groove and extending in the circumferential direction of the flange, said vertical and horizontal grooves both being radially open for the engagement of the locking portion, wherein:

[0003] - the vertical slot has an axially directed locking portion entry opening, and wherein,

[0004] - the horizontal slot is provided with an axially directed locking portion support surface, a locking projection and a movement end stop at the end of the horizontal slot remote from the vertical slot,

[0005] - having a fixing element which is designed with a latch which is fixed to the lampholder and which engages radially in the groove arrangement after the plugging and rotating movement in order to fix the lamp lens to the lampholder,

[0006] - have a rest flange as part of the lamp holder, against which the luminaire glass rests. Background Art

[0007] The cooking device lighting fixture is used to illuminate the cooking space of the cooking device so that the food being cooked in the cooking space can be observed during the cooking process and the cooking status can be understood.

[0008] Cooking appliances are characterized in particular by the fact that cooking fumes, so-called steam, are dispersed within the cooking space during cooking. Furthermore, high temperatures prevail within the cooking space (particularly in ovens or steamers). In so-called pyrolysis ovens, these temperatures can reach up to 450°C. Ovens in large kitchens and restaurants sometimes reach cooking temperatures exceeding 500°C.

[0009] Even if LED lighting devices are partially adopted in cooking appliances (such as ovens), traditional incandescent lamps still have their place in this field and remain highly relevant. This is partly due to established manufacturing technology. Such cooking appliance lighting is proven in terms of manufacture and use and is relatively cost-effective. On the other hand, there are purely technical reasons for using traditional lighting devices. Cooking temperature plays a particularly important role here, as it shortens the operating time of temperature-sensitive lighting devices.

[0010] Other problems with conventional cooking appliance lamps, such as the adhesion or sintering of the lamp glass in the lamp holder, have also been addressed. For example, EP 1 811 227 A1 shows a similar cooking appliance lamp. In this cooking appliance lamp, the lamp holder is fixed in a mounting recess in the cooking area wall and carries an incandescent lamp with a widely used G9 base. The lamp glass is fixed to the lamp holder via a plug-in rotational movement, similar to a bayonet-type fastening. A substantially radially acting, spring-elastic locking mechanism ensures that the lamp glass is securely and releasably fixed to the lamp holder.

[0011] To this end, the neck of the lamp glass has different bevels molded into the glass within the horizontal groove. These bevels ensure linear and punctiform contact of the radially acting locking elements, thereby preventing adhesion between the locking elements and the lamp glass. Furthermore, the locking elements, designed as elastic tongues, have a special design and, in conjunction with the horizontal groove, ensure a certain axial play at room temperature. This prevents the lamp glass from adhering to the base flange. This highly advantageous cooking appliance lamp is relatively complex to manufacture due to the precisely molded bevels and the special design of the radially acting locking elements. Summary of the Invention

[0012] The object of the present invention is therefore to provide a cooking appliance light, in particular an oven light, which is advantageously protected against adhesion of the light glass and has an alternative and more advantageous design in terms of production technology.

[0013] This object is achieved by a cooking appliance lighting device according to the invention, according to which:

[0014] - the fixing element has an elastic element which carries a locking portion,

[0015] - the locking portion has an axially downwardly directed locking surface which bears against an axially upwardly directed locking portion support surface,

[0016] The elastic element exerts an axially downwardly directed force on the luminaire glass in order to hold it against the contact flange.

[0017] The main advantage of the oven light according to the invention lies primarily in the design of the latch, which holds the light lens in the lamp holder. Although the latch engages radially in the horizontal groove, the axially oriented surfaces of the horizontal groove and the latch cooperate, making it unnecessary to form radially oriented bevels on the neck of the light lens.

[0018] The elastic deformation in the axial direction, ensured by the cooperation of the locking portion and the elastic element, and the axially directed elastic force generated thereby when the lamp glass is fixed, on the one hand securely hold the lamp glass on the contact flange of the lamp holder. On the other hand, they ensure simple release of the lamp glass when the lamp held in the lamp holder is to be replaced.

[0019] In a particularly preferred embodiment, it is provided that the locking portion is formed with a supporting projection which protrudes axially toward the locking portion support surface.

[0020] Here, only the supporting projections of the locking part interact with the locking part support surface of the horizontal groove, so that there is a substantially point-shaped contact surface between the locking part and the locking part support surface. This significantly reduces the risk of the locking part sticking to the locking part support surface of the horizontal groove. In this case, the supporting projections can be manufactured, for example, as stamped parts into the locking part formed from sheet metal.

[0021] In addition, it is stipulated that

[0022] - the locking protrusion is a threshold that protrudes axially upward relative to the support surface of the locking portion,

[0023] The locking part is provided at its horizontally pointing end with an inclined surface which faces the locking part support surface and is inclined in the direction of the locking part support surface.

[0024] In this embodiment, during the insertion and rotational movement to secure the lamp lens in the lamp holder, the locking portion is forced to move beyond its travel via the locking projection. This overtravel occurs within the rotational movement of the lamp lens. Thus, the locking projection prevents uncontrolled reverse rotation. The inclined surface formed by the locking portion facilitates this overtravel by sliding over the locking projection.

[0025] Furthermore, it is provided that the elastic arm as part of the fixing element carries the locking portion at its first end and is connected to a leaf spring at its second end, and that the leaf spring is axially elastic when elastic stress is generated and enables axial displacement of the locking portion connected to the elastic arm.

[0026] The leaf spring allows an additional axial travel of the locking element and in this way makes it possible, for example, to compensate for manufacturing tolerances which act on the base body or the neck of the lamp glass in an axially extended manner.

[0027] However, the axial mobility of the locking element, reinforced by the leaf spring, also allows for the provision of a seal, friction-reducing material, or the like between the contact flange of the lamp holder and the luminaire glass, without having to modify the cooking appliance light in terms of its design. In this regard, the oven light can be used according to the manufacturer's specific requirements without requiring any adjustments. Thus, for example, one and the same cooking appliance light can be used not only with a sealing ring between the luminaire glass and the contact flange, but also without such a sealing ring.

[0028] Furthermore, it is provided that the lampholder is formed with an annular wall standing on a horizontally oriented lampholder base, which surrounds the receiving space and has at least one receiving groove for a spring arm of the fastening element, in which the spring arm is inserted with radial play.

[0029] The possible radial play of the spring arms is another factor that allows for axial play in the design. When the axial displacement of the leaf spring is exhausted, the radial expansion of the spring arms allows the essentially horizontally positioned locking element to slide slightly, thereby allowing it to tilt. This creates the (albeit small) possibility of creating further axial play in the connection between the lamp holder and the lamp glass.

[0030] An important element of the present invention is characterized in that the leaf spring, the elastic arm and the locking portion form an elastic arrangement made of a spring-elastic sheet material, which:

[0031] - with radially directed and axially sprung leaf springs,

[0032] - having a radially directed and axially resilient locking portion, and

[0033] - optionally with axially directed and radially springy spring arms.

[0034] Furthermore, it is provided that the fastening element is fastened to the lampholder by means of a leaf spring, in particular when the leaf spring is part of a ring which is arranged in the receiving space and fastened to the annular wall or to the lampholder base.

[0046] In the figures, a cooking appliance light according to the present invention is generally provided with the reference numeral 10 in the form of an oven light.

[0047] The oven light 10 firstly comprises a lampholder 11 , the base block 12 of which in two sockets 13 arranged on the underside of the base block respectively carries a base contact 14 and a connecting contact 15 .

[0048] Furthermore, the base block 12 also accommodates the protective earth contact 16 and also supports the fastening ring 17 in a receiving space 18 formed by an annular wall 19 which has a retaining flange 21 at its end surrounding the insertion opening 20 .

[0049] The oven light 10 further comprises a lamp 22 which is designed in the present case as a G9 lamp and whose bulb 23 carries a base 24 with base contacts 25 at its end facing the base block 12 .

[0050] At its lower end facing the base block 12 , the lamp glass 26 is designed as an annular neck 27 which surrounds a receiving opening 28 for receiving the lamp 22 and carries fixing means 29 on the outer circumference in the present exemplary embodiment.

[0051] The lamp glass 26 is fixed to the lamp base 11 via a fixing ring 17, which will be described in detail below. The lamp glass 26 forms the upper end of the oven lamp 10, and the lamp base 11 forms the lower end of the oven lamp 10, wherein the geometric longitudinal center axis LM is arranged from top to bottom, that is, vertically through the oven lamp 10.

[0052] Figures 2 to 4 In a different view, namely in a perspective view from above (see Figure 2 ), a view from directly above (see Figure 3 ) and based on Figure 3 Sectional view along the midline IV-IV (see Figure 4 ) shows the fixing ring 17.

[0053] The fixing ring 17 first comprises a base 30, a flat, annular metal part equipped with a series of functional mechanisms. The base 30 is initially formed with a central base recess 31, through which the base 24 is inserted and into which retaining springs 32 engage, securing the base 24 in the socket block 12. Diametrically opposed latching springs 33 secure the socket block 12, and thus the oven light 10, to the wall of the cooking appliance by accommodating a wall section between them and the retaining flange 21. Circumferentially offset by 90° from the latching springs 33, the fixing ring 17 comprises two diametrically opposed securing elements, generally designated by reference numeral 34, which are used to releasably secure the lamp lens 26 to the socket block 12.

[0054] Holding tabs 35 , which are also provided on the outer circumference of the base 30 , serve to fix the fastening ring 17 on the inner surface of the annular wall 19 of the base block 12 .

[0055] Each fixing element 34 first has a spring arm 36, which extends axially parallel to the longitudinal center axis LM from the base 30, that is, is oriented essentially vertically. The spring arm 36 holds a locking portion 37 on its end facing away from the base 30, which is oriented horizontally and points radially inwards, that is, in the direction of the longitudinal center axis LM.

[0056] The end of the spring arm 36 that faces the base is connected to a leaf spring 38. The leaf spring 38 is formed into the base 30 by two parallel notches 39 on either side of the spring arm 36. A fixing ring 17 made of a spring-elastic sheet metal (which is a stamped and bent part) ensures the resilient deflection of the locking portion 37 and the leaf spring 38 in the axial direction in the area of ​​the fixing element 34, while the spring arm 36 is deflectable in the radial direction.

[0057] The locking portion 37 is formed with a locking surface 40 pointing toward the base 30, ie, downward, from which a supporting projection 41 projects axially toward the base 30, ie, downward. The supporting projection 41 is stamped into the locking portion 37 by a corresponding pressing process.

[0058] The free end of the locking portion 37 pointing in the circumferential direction is configured as a wing 42 and is separated from the spring arm 36 by a not-shown cutout. As a result, the wing can be placed axially upward, i.e. in the direction of the luminaire lens 26 and forms an inclined surface 43 pointing towards the base 30.

[0059] Figure 5 The side view shows the lamp lens 26 with a cap-shaped cover 44, which is hollow on the inside and carries a neck 27 on its underside facing the base block 12. The neck 27 is tapered relative to the circumference of the cover 44, so that a receiving flange 45 is formed in the stepped transition between the neck 27 and the cover 44.

[0060] The neck 27 carries a fixing means, generally designated by reference numeral 29. The fixing means is formed by a vertical groove 46 introduced into the neck 27, which merges into a horizontal groove 47. In the present exemplary embodiment, both grooves 46, 47 are formed on the outer circumference of the neck 27 and are open radially outward. Furthermore, the vertical groove 47 has an axially oriented locking element entry opening 48, so that when attached to the securing ring 17, the locking element 37 can be inserted into the vertical groove 46 using a plug-in movement X and introduced into the horizontal groove 47 using a rotational movement Y.

[0061] The horizontal groove 47 is provided with a locking support surface 49 pointing axially upward, i.e., toward the cover body 44. The locking support surface first has a tensioning bevel 50 in the entry region of the horizontal groove 47 and a locking projection 51 adjoining the tensioning bevel, which narrows the horizontal groove 47 in the axial direction. At its end facing away from the vertical groove 46, the horizontal groove 47 forms a movement end stop 52 by a wall section.

[0062] With the help of Figure 6 (Based on lamp glass 26 Figure 5 As can be seen from the top view of the view arrow VI in FIG, two diametrically opposed fixing devices 29 are provided on the neck 27 of the lamp glass 26.

[0063] Figure 7 An axial section of the oven light 10 is shown in a standard configuration, wherein the section position corresponds to the position of the fixing ring 17 according to Figure 3 Sectional view along the cutting line IV-IV.

[0064] This view first shows that the lampholder 11, or more precisely the lampholder block 12, has a lampholder base 53 which holds the hub 13 downward and on which rests the annular wall 19 extending in the direction of the lamp glass 26. The base 30 of the securing ring 17 is oriented parallel to the lampholder base, while the securing element 34, the latching spring 33 and the retaining tabs 35 extend essentially axially in the direction of the lamp glass 26.

[0065] The annular wall 19 is formed on its inner periphery with a retaining recess 54, into which the retaining tabs 35 engage and thus secure the fixing ring 17 to the base block 12. The lamp 22 is arranged in the receiving cavity 18 of the base block 12 and in the lamp glass 26, wherein the lamp base 24 is embedded in the base block 12 through the base recess 31 of the retaining ring 17 and is anchored there by the retaining spring 32.

[0066] In addition, by Figure 7 It can be seen that the locking portion 37 engages radially inwardly in the horizontal groove 47 and rests there only with its supporting projections 41 on the locking portion support surface 49 of the horizontal groove 47. In other words, the locking portion and the locking portion support surface 49 form a point-shaped contact surface or, depending on the design of the supporting projections 41, a linear contact surface. The significant reduction in the contact surface between the locking portion 37 and the horizontal groove 47 achieved thereby effectively prevents adhesion or sintering of the lamp lens 26 to the locking portion 37.

[0067] Figure 7 It is also shown that the support flange 45 of the lamp glass 26 rests securely on the retaining flange 21 of the base block 12 and thus relatively effectively prevents the ingress of cooking fumes between the lamp glass 26 and the base block 12 .

[0068] Figure 9 and Figure 10 The cooperation between the fixing ring 17 of the oven light 10 and the light glass 26 is explained for fixing the light glass 26 on the lamp holder block 12 .

[0069] First, the lamp lens 26 is moved in the insertion direction X toward the lamp holder block 12, wherein the neck 27 is inserted into the receiving cavity 18 of the lamp holder block 12 through the insertion opening 20 of the annular wall 19. Here, the locking portion 37 is aligned with the vertical groove 46 and enters the vertical groove. The wings 42 in the circumferential direction are then rotated in the direction of the arrow Y. Figures 9 and 10 During the transition from the locking projection 51 to the locking projection 51, the locking projection 37 strikes the tensioning bevel 50 and slides on it to minimize frictional resistance. In this process, at least the locking portion 37 and, if necessary, the leaf spring 38 are preloaded with spring-return elasticity, which causes both the locking portion and the leaf spring to deflect in the vertical direction. The tensioning bevel 50 transitioning into the locking projection 51 causes an overtravel movement until the locking portion 37 is in the section of the horizontal groove 47 between the locking projection 51 and the end stop 52 of the movement (see FIG. Figure 10 The spring force that is built up pulls the luminaire glass 26 onto the retaining flange 21 (see Figure 7 ). Therefore, the lamp glass 26 is mounted on the lamp holder without any gap.

[0070] The combination of the axially deflectable locking portion 37 and the axially deflectable leaf spring 38 allows for a large spring travel and therefore, primarily, for a large tolerance compensation of the manufacturing tolerances of the lamp glass 26 and the lampholder block 12. However, the overall large spring travel of the fixing element 34 also allows the oven lamp 10 to be used in special applications, such as, for example, in Figure 8 Here, select something like Figure 7 However, a seal 55 is provided between the abutment flange 45 of the lamp glass 26 and the retaining flange 21 of the lamp holder block 12. The seal has a certain thickness in the axial direction and thus separates the lamp glass 26 from the lamp holder block 12. Figure 8 It is shown how the leaf spring 38 of the fixing element 34 of the fixing ring 17 is deflected vertically in the direction of the lamp glass 26 in order to compensate for the axial distance between the lamp glass 26 and the base block 12. The resulting spring restoring force holds the lamp glass 26 securely against the base block 12 and achieves a sufficient contact pressure of the support flange 45 on the seal 55 and also the required contact pressure between the seal 55 and the holding flange 21.

[0071] Therefore, the main advantage of the elastic arrangement of the leaf spring 38, the locking part 37 and the elastic arm 36 is that, despite the larger manufacturing tolerances, a sealing arrangement can be provided between the lamp holder block 12 and the lamp glass 26 without having to modify the design of the oven lamp 10. Such a sealing assembly is useful in any location where a high smoke load is present. In addition to ovens, such a sealing arrangement is particularly suitable for industrial and commercial use, such as Figure 8 As an example, a steam cooking appliance is shown, in which a high humidity load is present in the cooking space.

[0072] In summary, the present invention thus provides an advantageous oven light 10 that, compared to the prior art described above, allows for a simplified design of the lamp glass 26 or the fastening means 29 formed from the lamp glass 26. For this purpose, axially acting locking elements are provided instead of radially acting locking elements. To reduce the contact surface between the fastening means 29 of the lamp glass 26 and the fastening element 34 of the lamp holder 11, it is provided that the locking portion 37 is provided with a supporting projection 41 pointing in the direction of the locking portion support surface 49. This reliably prevents adhesion between the fastening element 34 on the lamp holder 11 and the fastening means 29 on the lamp glass 26.

[0073] Another major advantage lies in the design of the fastening element 34 of the lamp holder 11. The combination of a vertically deflectable leaf spring 38 and a vertically deflectable latch 37 allows for bridging large axial tolerances between the lamp lens 26 and the lamp holder block 12. These axial tolerances can be due to manufacturing tolerances, but in particular, they also allow for the interposition of a sealing component between the lamp lens 26 and the lamp holder block 12 without having to modify the oven lamp design.

[0074] Furthermore, radially deflectable spring arms 36 are advantageous in the case of extreme axial tolerances in order to bridge the axial distance between the lamp lens 26 and the base block 12. Figure 8 In order to achieve a greater axial distance of the sealing assembly 55 in the embodiment of the present invention, which cannot be compensated by the axial deflection of the leaf spring 38 or the locking portion 37 alone, the radial deflection of the elastic arm 36 can allow further axial clearance space.
