Description

The invention relates to a household appliance, in particular cooking appliance with a device muffle, on whose opposite side walls corresponding lateral guide elements are formed, which in each case support an insertion part in a horizontal cooking level. Moreover, the invention relates to a method for producing the guide elements.

Out DE-A-1 579 669 is a generic cooking appliance with a device muffle known. On the two side walls of the muffle a number of guide rails are formed, which are vertically spaced from each other. By means of the guide rails, a baking tray can be inserted in a horizontal cooking level in the device muffle. Each of the guide rails is embossed in the metal sheet of the side walls.

Out US-A-2,944,139 is another cooking appliance with a device muffle known. As a result, rods are hung in the opposite side walls in a horizontal plane. These rods extend along the side walls and are releasably supported. Racks can be hung on the bars. So that baking trays can be inserted into the device muffle, a number of guide elements is formed on each of the racks.

The object of the invention is to provide a household appliance, in particular cooking appliance with a Gargerätmuffel and a manufacturing method in which a tilting security of a plug-in part is improved in an easily implementable manner.

The task is solved by a household appliance, in particular cooking appliance on each side wall at least one of the guide elements independently of the others releasably supported.

Due to this independent solubility, the guide element can be taken out of the device muffle, as long as it is not needed to support a plug-in part. Superfluous guide elements must therefore not be heated in the cooking mode. The cooking operation can therefore be carried out thermally favorable only with such guide elements that are needed to support the insertion parts. In addition, the guide elements can be held in a user-selected arrangement in the device muffle.

Characterized in that the guide element has at least one bore into which a pressing part can be pressed, a correspondingly complex assembly step for welding of additional elements with the guide element is avoided. The height stop can prevent tilting of the insertion part of the front Muffetöffnung, provided that the insertion part is partially inserted into the cooking chamber. Additional welding operations for connection to the insertion part are therefore not necessary. In this way, the height stop can be formed as a wire bow, which is pressed into the corresponding holes of the guide member.

The object is also achieved by a method for producing a guide element for supporting a insertion part in a device muffle of a household appliance, in particular cooking appliance, wherein the guide element is made of a rod-shaped manufacturing part, are introduced into which holes and then trained as a wire hanger height stop in holes of Guide element is pressed. According to the invention, the guide elements are thus not integrated in a rack or grid arrangement. With the exception of the guide elements can therefore be dispensed with additional components, such as the frame or grid in the oven. In this way, the guide element can be used and removed independently of other insertion devices.

With a view to a compact and simple design, preferably, each of the guide elements can be designed rod-shaped and without moving parts. The less material is used for the guide elements, the less heat energy is needed to heat the cooking chamber. Particularly advantageous as a material for the guide element, a rigid elongated rod made of heat-resistant steel can be used.

It is preferred if a number of mutually separate guide elements is arranged on each muffle side wall. Therefore, according to the invention, a mechanical connection of the guide elements is dispensed with. This is thermally advantageous compared to known frame arrangements with guide elements which are connected to one another. In such frame arrangements, only the entire frame assembly can be taken out of the cooking chamber, but not individual elements of the arrangement.

It may be advantageous if the guide element is mounted via an adapter in the muffle side wall. The interposed adapter, regardless of the stability of the muffle side wall and regardless of the design of the guide element and / or the extraction system, a reliable support in the muffle side wall can be achieved. The adapter can be fixed like a bearing bush in the muffle side wall. Alternatively, the adapter may be placed on end portions of the guide member.

It is advantageous if the guide element is mounted with its two end portions on a muffle wall or alternatively on a side wall and a rear wall. Additional holders, which connect the guide element with the side wall, therefore need not be attached to the guide element.

For a stable mounting, it is preferred if the guide element is held both on a side wall and on the rear wall of the muffle. As a result, the guide element is much more resistant to tilting moments that result from a weight load.

The guide element may preferably have at least one end section which is bent at an angle in a horizontal cooking plane. As a result, its dimensional stability is increased, whereby a corresponding reduction of the required material thickness is made possible. In particular, at least one of the end sections of the Guide element bent L-shaped. In this way it is possible to support the guide element with its muffle front end in the muffle side wall, while it is supported with its muffle back end in the muffle back wall.

The dimensional stability of the guide element can be increased if it consists of a solid material. This is also advantageous in terms of manufacturing technology, since there are more design options for machining in particular the end sections of the guide element and / or extension system. However, if thermal aspects are in the foreground, a corresponding design of the guide element made of a hollow material may be preferred. In this way, the amount of material per guide element can be reduced. A heat energy input required during the heating process can therefore be reduced.

For a shapely and cost-effective design of the guide element is advisable to use a round material for the guide element. For reasons of stability, however, the use of a guide element folded in cross section may be preferred. With a canted cross-section, the material thickness can be reduced with substantially constant stability compared to the round material.

It is still an embodiment that an insertion stop is present, which limits the insertion path of an insertion part in the horizontal direction and which is preferably pressed in a bore of the guide element. The insertion stop can be designed as a wire part.

For example, a first additional part may be formed as a slot stop which limits the insertion path of a slide-in part in the horizontal direction. A second insertion part can be formed muffelfrontseitig on the production part and serve as a height stop. The insertion stop may be formed as a wire part, which is also pressed into a bore of the guide member.

It is advantageous if the guide element is at least partially supported by a floating bearing on the muffle wall. This can cause a thermal expansion of the production part be balanced without transmitting tension or forces on the muffle side wall.

In addition, the guide element can be provided at least in sections with a reduced diameter. Thus, it is preferred in terms of manufacturing technology if a bearing pin is formed as an end section of the guide element with a reduced diameter. The provided with the bearing pin end portion of the guide element can also be bent if necessary.

In the FIG. 1 is a cooking appliance with an inside provided with an enamel layer Gargerätemuffel 1 shown. The cooking appliance has a hinged door 3 for closing a front-side muffle opening 5. The hinged door 3 is in the closed state in contact with the muffle opening 5 moving front flange 7. On the opposite side walls 9 of the cooking appliance muffle 1 corresponding lateral guide elements 11 and a later-described extraction system, consisting of two telescopic extensions 59 are supported. The telescopic extensions 59 are supported in a topmost of four horizontal Garraumebenen. In the following four lower Garraumebenen each side guide elements 11 are supported. On the two corresponding lowermost guide elements 11, a baking sheet 13 is supported, which is partially pushed out of the cooking appliance muffle 1. Each of the guide elements 11 is formed as a rod-shaped steel profile part or manufacturing part, which has a circular cross-section and consists of a solid material.

The guide elements 11 and / or the telescopic extensions 59 can be arranged by a user in any manner in the Gargerätemuffel 1. For this purpose, the guide elements 11 and telescopic extensions 59 are mufflefrontseitig each mounted in a bearing bush 15. In the area of a muffle rear wall 17, the guide elements 11 are each mounted in a mounting opening 19 of a wall element 21. Both the guide elements 11 and the telescopic extensions 59 are tool-free by the user from the muffle 1 to solve.

The muffle front side mounting of the guide elements 11 in the bearing bushes 15 is in the FIG. 2 shown in detail. Consequently, the in the FIG. 3 illustrated as a single part bushing 15 hollow cylindrical with an outer edge flange 23 is formed. This is supported inside a cooking chamber of the muffle 1 inside of the muffle side wall 9. The muffle side wall 9 consists of a thin steel sheet with a wall thickness in the range between 0.3 to 0.7 mm. As well as from the FIG. 3 shows, the edge flange 23 of the bearing bush 15 goes on garrauminnenseitig in an insertion cylinder 25. The insertion cylinder 25 serves as an insertion aid for a bearing pin 27, which is formed on a rod end of the rod-shaped guide element 11. In the region of the Einführzylinders 25 of the bearing bush is according to the FIG. 3 a hexagon socket provided in order to mount with a corresponding tool, the bearing bush 15 in an opening 10 of the muffle side wall 9 can.

A the cooking chamber 25 facing insertion opening of the bearing bush 15 is moved from the front side of a front flange 31. The front flange 31 of the bearing bush 15 is axially spaced from the edge flange 23. In between, an annular groove 33 is formed. This serves, as will be described later, as a mounting portion for suspending the telescopic extensions 59.

The bearing bush 15 is provided on the outer circumference with an external thread 35 through which the bearing bush according to the FIG. 2 is screwed into the muffle side wall 9. However, a corresponding mating thread 39 is not formed in the thin-walled muffle side wall 9 itself. Rather, the mating thread 39 is formed in a securing element 37. The fuse element 37 is according to the FIG. 2 on the outside with the muffle side wall 9 in Appendix. It is designed as an elongate profile part with the corresponding mating threads 39 for the bearing bushes 15. The Profile member 17 is a U-shaped profile in cross-section steel sheet, whereby it remains torsionally rigid and dimensionally stable even under thermal stress. Each of the mating thread 39 is incorporated in the manner of a metal nut in the profile part 37. The profile part 37 extends in a vertical direction over all in the FIG. 1 Due to the large-scale investment of the profile part 37 on the outside of the side wall 9, the bushings 15 are stably fixed against tilting moments, in spite of the thin-walled muffle side wall 9. Approximately midway between the two legs of the U-shaped security element 37th the mating threads 39 are formed.

The bearing bush 15 is guided with its external thread 35 with a clearance through the opening 10 of the muffle side wall 9. The bearing bush 15 is therefore not bolted directly to the muffle side wall 9. Rather, the muffle side wall 9 is clamped between the securing element 37 and the edge flange 23 of the bearing bush 15.

In the two legs 41 of the U-shaped profiled part 37 are according to the FIG. 2 hook-shaped recesses 43 cut in which a wire spring 45 is supported. This extends transversely to the legs 41 of the profile part 37. It is in the FIG. 2 the bearing pin 27 of the guide member 11 between two spring legs of the wire spring 45 securely locked. For this purpose, the bearing pin 27 of the guide member 11 at its insertion end a locking groove 47, in which the two spring legs of the wire spring 45 are engaged. At its insertion end, the bearing pin 27 is formed with an insertion cone 49, which serves as an insertion aid for the bearing pin 27. A transition section 46 between the insertion cone 49 and the locking groove 47 expands in the direction of the insertion cone 49 in a conical manner.

Like from the FIG. 2 shows, the bearing pin 27 of the guide member 11 is reduced to a diameter which allows a positive storage in the bearing bush 15. As a result, a play-free mounting of the guide member 11 is achieved in the bearing bush 15. This is further supported by a contact shoulder 51 of the bearing pin 27, which is in contact with the front flange 31 of the bearing bush 15.

In addition, press in the FIG. 2 the two opposite spring legs of the wire spring 45 on the cone-shaped transition portion 46 of the bearing pin 27th

As a result, the bearing pin 27 is pulled with a pressure force into the bearing bush 15 and pressed permanently against the front flange 31 of the bearing bush 15.

In the FIG. 4 the bearing bush 15 is shown in a modification. Unlike the one in the FIG. 3 shown bearing bush is in the bearing bush of the FIG. 4 dispensed with the front flange 31. The bearing bush 15 therefore has garrauminnenseitig only the edge flange 23. As based on the FIG. 2 explained, the abutment shoulder 51 is pressed in a corresponding manner against the edge flange 23 of the bearing pin 27.

As a further difference from the previous embodiment, the garraumaußenseitige end of the in the FIG. 4 shown bearing bush 15 closed. Thus, with the guide element 11 removed, heat dissipation from the cooking chamber through the bearing bush 15 is reduced. As the securing element 37 for the bearing bush 15, a securing nut is provided instead of a single profile part for all bearing bushes 15. This is in the FIG. 4 screwed onto the external thread 35 of the bearing bush 15. In order to enable a locking of the bearing pin 27 in the bearing bush 15, a slot 52 is provided in the outer periphery in the region of the closed end of the bearing bush 15. In the slot 52, a spring leg of the wire spring 45 is inserted, which engages in the locking groove 47 of the bearing pin 27.

In the FIG. 5 a taken out of the Gargerätemuffel 1 guide element 11 is shown. The bearing pin 27 is formed on a rod end of the guide member 11 with a reduced diameter. Since the guide element 11 consists of a solid material, manufacturing technology can be easily formed, for example by means of a lathe of the bearing pin 27 at the rod end. The provided with the bearing pin 27 rod end of the guide member 11 is also bent angularly. A bending necessary for this purpose is compared to a hollow material in the solid material used here, manufacturing technology easily feasible.

The guide elements 11 and telescopic extensions 59 are each independently formed and inserted into the muffle 1, as is apparent from the FIG. 1 is apparent. Accordingly, they can be taken independently of each other from the oven, unless they are needed to hold a food support. Thereby thermally advantageous material entry into the cooking appliance muffle 1 can be kept as low as possible.

The L-shaped guide element 11 is formed with a leg along the muffle side wall 9 elongated leg, which serves for guiding and supporting of insertion parts. The L-shape of the guide element 11 makes it possible to support the guide element 11 with its muffle back-side bar end 54 on the muffle rear wall 17 and with the bent muffle front side bar end on the muffle side wall 9. By this holder on two different muffle walls, the guide member 11 is more resistant to tilting moments.

Muffle front side is provided on the guide member 11, a height stop 53 as a tilt protection for insertion parts. This is pressed as a bent steel wire bracket with its two ends in corresponding holes of the guide member 11. Accordingly, a further bore in the guide element 11 is formed in the region of the muffle backside rod end 54 offset by 90 °. In this a steel pin is pressed, which serves as a slot stop 55 for an insertion part.

In the FIG. 6 an alternative use of the bearing bush 15 is shown. As a result, no rod-shaped guide element 11 is inserted into the bearing bush 15. Rather, a retaining plate 57 of the in the FIG. 1 shown telescopic extension 59 mounted in the annular groove 33 of the bearing bush 15. The telescopic extension 59 has according to the FIG. 1 a rear pin 61 for mounting on the muffle back wall 17. The pin 61 is formed like the rear rod end 54 of the guide elements 11.

The muffle front side holding plate 57 is formed as a steel sheet with a punched slot 63. The slot 63 extends perpendicular to the elongated telescopic extension 59 and serves to hook the retaining plate 57 into the annular groove 33 of the bearing bushing 15. For this purpose, the slot 63 is punched like an inverted keyhole with a widened insertion section 65 and a narrow securing section 67 in the holding plate 57 , The diameter of the widened insertion section 65 is greater than the diameter of the front flange 31 of the bearing bushing 15. Accordingly, the retaining plate 57 can easily be guided over the front flange 31 of the bearing bush 15 and be hung in the annular groove 33. The wall thickness of the holding plate 57 is smaller than a groove width of the annular groove 33 of the bearing bushing 15. The opposite lateral boundary edges of the securing portion 67 are in the FIG. 6 disposed within the annular groove 33 of the bearing bush 15. As a result, an axial movement of the suspended holding plate 57 along the bearing bush 15 is prevented.

Below the elongated hole 63, a leaf spring 69 is riveted by means of a rivet 71 with the retaining plate 57. The leaf spring 69 acts like a locking element. In the FIG. 6 the leaf spring 69 is shown in its locking position. In this position, an upper locking edge 73 of the leaf spring 69 is in contact with a periphery of the front flange 31 of the bearing bush 15 or slightly spaced therefrom. An accidental movement of the holding plate 57 upwards is thus prevented by the leaf spring 69. Accordingly, therefore accidental release of the holding plate 57 is prevented by the bearing bush 15.

The leaf spring 69 has according to the FIG. 6 an operating portion 75. This can be pressed in the direction of the arrow shown, whereby the locking edge 73 is pivoted in the direction of the arrow shown in the cooking chamber. In this position, the locking edge 73 of the leaf spring 69 is disengaged from the bearing bushing 15. The retaining plate 57 of the telescopic extension 59 can therefore be raised for removal of the telescopic extension 59, so that the bearing bush 15 can be led out of the insertion section 65 of the support plate 57.

When removed telescopic extension 59, the leaf spring 69 is located with its locking edge 73 directly on the support plate 57 and overlaps the insertion section 65 of the slot 63. For re-hooking the telescopic extension 59, the bearing bush 15 through the slot insertion section 65 of the support plate 57 to lead. In this way, the bearing bush 15 pushes the leaf spring 69 with its locking edge 73 of the holding plate 57 away.

Subsequently, the telescopic extension 59 can be slightly lowered by the user until the bearing bush 15 is in the narrow securing portion 67 of the elongated hole 63, as shown in the FIG. 6 is shown. In this state, the leaf spring 69 is automatically jumped back into its locking position. The leaf spring 69 can only be tilted from the locking position to an unlocking position when a user presses on their operating portion 75. In the unlocked position, the holding plate 57 of the telescopic extension 59 can be raised slightly by the user. In this case, the bearing bush 15 is arranged in the insertion section 65 of the elongated hole 63. In this state, the holding plate 59 can be released by an axial movement of the bearing bush 15.

The FIGS. 7 and 8 are concerned with the storage of the rod-shaped guide member 11 and the bearing pin 61 of the telescopic extension 59 on the rear side wall of the cooking appliance muffle 1. As already mentioned, this garrauminnenseitig each side a wall element 21 is arranged with corresponding mounting holes 19. In the mounting holes 19, the guide elements 11 and the telescopic extensions 59 are mounted in the manner of a floating bearing. This means that the respective rod end or the bearing journal 61 can move in a depth direction and thus heat-related stresses are avoided. The wall element 21 is according to the FIG. 8 formed as an angled U-profile part of a steel sheet with a large heat-resistant rigidity. The U-profile part 21 has at its one leg a right angle bent abutment flange 77. This is mounted over locking screws 79 over a large area in contact with a mounting surface of a muffle back wall side air guide plate 81. The air guide plate 81 separates a ring heater, not shown, and a fan from the cooking chamber. As a result of this mounting on the air guide plate 81, it is achieved that no additional openings have to be formed for fastening the U-profile part 81, for mounting the telescopic extension 59 or for mounting the guide element 11 in the muffle rear wall 17. The rear side wall of the cooking appliance muffle 1 is according to the FIGS. 7 and 8 from the muffle rear wall 17, the air guide plate 81 and the garrauminnenseitigen wall elements 21st

The angled U-profile part 21 also has a mounting flange 83. This is offset relative to the abutment flange 77 in the direction of the cooking chamber. In the mounting flange 83, the mounting holes 19 for the guide elements 11 and for the bearing pin 61 of the telescopic extension 59 are formed in a vertical row. As in particular from the FIG. 8 shows, each of the mounting holes 19 includes a cup-shaped edge embossing or a collar 85 which projects into the cooking chamber. This Collar 85 serves as an abutting edge during the insertion of the bearing journal 61 or of the rod end 54.

According to the FIGS. 7 and 8 an additional aperture 87 is set on the wall element 21 in order to shield the U-profile part 21 from the cooking space. According to the figures, the panel 87 is designed as a U-shaped sheet steel profile part, which has corresponding to the mounting holes 19 of the U-profile part 21 aperture 89. Their diameter is made slightly larger than the diameter of the collar 85 of the mounting opening 19. Thus, the cup-shaped collar 85 protrudes in the assembled state according to the FIG. 7 through the aperture 89 in the oven. Despite the upstream aperture 87, the collar 85 can thus fulfill its function as an insertion aid for the bearing journal 61 or the rod end 54.

The cooking chamber facing surface of the aperture 87 is surface-finished according to the muffle walls, d. H. provided in the present case with an enamel layer. As a result, the aperture 87 together with the wall element 23 optically largely fades into the background. To avoid installation-related scratches on the air guide plate 81, the aperture 87 is not directly in contact with the air guide plate 81. Rather, the aperture is slightly, d. H. spaced at least non-contact from the air guide plate 81. Corresponding damage to the enamel layer of the air guide plate 81 through the aperture 87 can be avoided.
