Description

The invention relates to a device for closing the Access opening of an interior of a household appliance, in particular a household oven, a household refrigerator and / or freezer, a household dishwasher. or a household washing machine.

From EP 1 106 932 A2 a door for a Garofen, preferably for the household, known with at least two spaced apart support elements, which are made of a temperature-resistant mechanically stable polymeric material, in particular a thermoplastic or a thermosetting polymer material, and with an outer pane, with the carrier elements are connected via a respective adhesive bond. On the two support elements receiving means and / or fastening means are arranged, which are formed with the associated support member as a continuous molding and for receiving or securing another door pane, in particular an inner pane or washer, and / or at least one other door component, in particular in each case a door hinge and / or at least a third door pane and / or a door handle are provided. One or more of the functional parts of the door, in particular the door handle or at least one of the door panes, may be integrated with the carrier elements to form common moldings and then consists of a common polymer material. The support elements may be formed as hollow profile parts, but also solid. As suitable high-temperature-resistant plastics, EP 1 106 932 A2 in column 7, from line 33 to column 8, line 5, specifies some possible plastics. A cooking oven with a furnace muffle with a feed opening for the introduction of food to be cooked is then equipped with such a door for closing the feed opening.

To move this known door relative to the loading opening are two door hinges as connecting elements for connection provided with the remaining cooking oven, each in a cavity of the carrier element or on a carrier element, preferably resilient, are attached. A Such resilient compliance can, for example, with a Snap or locking connection can be achieved, which then the impulses when opening the door from the door hinge to the Support element are damped. The two support elements of known door extend to the lower edge of the outer pane and each have a vertical slot-shaped Breakthrough to perform in the housing of the oven too fastened and located opposite to the carrier element Hinge part swiveling hinge part.

In Applicant's household cooking ovens or stoves available on the market, a door can be pivoted about a pivot axis extending horizontally under the door by means of two door hinges. The door hinges each have in cross-section U-shaped hinge housing made of sheet steel, in each of which two embossments are provided with metric threads for securing the hinge in similar to those described in EP 1 106 932 A2 constructed and arranged, but formed of sheet metal support elements. Within the hinge housing a tension spring is arranged, which is designed as a helical spring and exerts a restoring force on the open door to push the door when opening or the movement upwards against the feed opening or its edge. This also causes a damped movement of the door down to the open position. One end of the tension spring is connected at the end of the housing by a bolt to the housing. The other end of the tension spring is also suspended in a bolt which is movably guided in two elongated holes of the housing. This further pin actuates a pull lever, which is connected via a further bolt with a Festarm. The arm exits or protrudes from the hinge housing and connects to the hinge bearing on the hearth body. When turning the Festarmes for example, 87 degrees, the built-tension spring is stretched by 12 mm. If the closed door is opened by pivoting down, so the arm of each hinge via the pull lever actuates the tension spring, which is stretched more and more with increasing door opening angle. When the door is open, the spring force is approximately equal to the total weight of the door to prevent the door from falling too fast. In the end position at maximum opening angle stops are provided by which the door can not be pivoted further down. The spring force of the tension spring is assigned individually to the respective door weight. To close the door, a further, arranged in the hinge housing compression spring is used in addition to the tension spring, which is supported in the pull lever on one side, guided by a connecting rod, which actuates the pressure lever via a bolt. The pressure lever is arranged as a U-shaped rocker and presses on the front edge of the Festarmes. The roller mounted in the pressure lever rolls over the contour or front edge of the Festarmes. When the door is open at an angle of approx. 30 degrees, an ever-increasing air gap is created between the roller and the fixed arm edge. When closing the door, the roller presses more and more against the edge of the fixed arm over the last 30 degrees. By a corresponding contour of the hard arm now, for example, a kind of open door at 15 degrees or by the Festarmkontur supported contact pressure of the door when closing is increased or reduced.

The hinge housing with the functional parts contained therein is on this as well as on the most on the Market devices integrated in the door, while the in the hinge bearing hinged and mounted counter lever of the Hinge, often referred to as a hinge sword is, in the case of the oven usually below or is attached to the side of the feed opening. Further includes the well-known hinge still a so-called release lever, who makes it possible through his position, the Hinge hinge in the hinge bearing or wait.

From DE 198 24 148 A1 a further door hinge for cooking ovens is known with only one tension spring and corresponding transmission mechanisms, wherein also the hinge housing is arranged with the tension spring in the door and only the protruding from the door housing lever or arm in the associated seat or hinge side the loading opening is attached.

Also DE 696 14 247 T2 discloses a similarly constructed door hinge for a cooking oven with integrated in the door hinge housing with tension spring and other mechanical parts as well as a fixed to the housing of the Garofarm or lever arm. The connection between the spring and the hook-shaped tension member is made by a pair of rollers which are coaxially and rotatably mounted on a shaft and run along the inside of the rear wall of the frame during the movement of the tension member and the extension or compression of the tension spring. In a middle portion of the lever, near its outside, there is mounted a pivotal blocking device or locking lever to hold the oven door or oven door in a middle, open position. The hinge according to DE 198 24 148 A1 has a frame with U-shaped cross section, which is firmly connected to the oven door and has a pin in which one end of a lever is rotatably mounted. Another end of the lever extends outside the frame and is fixedly inserted in a seat laterally of the feed opening of the hearth. The frame is thus pivotable with respect to the lever about the axis of the pin, whereby an axis of rotation or pivot axis is formed for the door. It is also arranged in the frame, a tension spring, which counteracts the pivoting movement of the door when opening. One end of the tension spring is connected to the frame and the other end to the middle portion of the lever via a bent steel wire tension member. This tension element is inserted in a recess which is formed in an edge region of the lever and with the oven door closed with respect. The axis of the pin forms a lever arm for the tensile force exerted by the tension spring to increase the closing force when closing the door.

EP 0 723 116 A2 discloses an oven door in which two support elements made of aluminum that run vertically and parallel to one another and are substantially U-shaped are adhesively bonded to an outer pane. The support elements extend to the lower edge of the outer pane and take down each a door hinge part with a tension spring. For performing the respective other, attached to the housing of the oven door hinge part an opening in each support member is formed in each case. The support elements have on their inner sides grooves for receiving an inner pane which covers the entire feed opening. Between the outer pane and the inner pane, a space open at the bottom is formed for cooling the door by natural air convection.

In addition to such door hinges in which the hinge housing is arranged with the tension spring in the door itself, door hinges are also known in which the free lever arm or arm is mounted in the door and the remaining parts including the tension spring are mounted in or on the housing of the Garofens , Such door hinges are known, for example, from DE 1 779 221 B1 or DE 2 025 542 A or DE 26 02 275 A1 or DE 2 037 243 A or DE 44 43 098 A1 or DE 39 33 719 C2 or DE 195 48 512 A1 or DE 196 04 435 C2 known.

In DE 196 04 435 C2 , a carrier part is fastened to a door for closing an oven muffle of a cooker in the base region in two lateral regions. In each carrier part in each case a plug-in part of a hinge is inserted and mounted pivotably on a hinge axis. With a bearing hook the male part is hooked on the other side in a receiving area of a hinge holder, which is attached to the stove or a mounting rail of the stove. The pivot bearing for pivoting the door is thus arranged in this known hinge mechanism in the door. About springs in DE 196 04 435 C2 nothing is said.

At the loading door for a household electric stove according to DE 39 33 719 C2 is one against the inertia of the loading door in the open position directed acting pneumatic Damper in conjunction with a spring element such coupled to the loading door that the counteracting Influence essentially on the swivel opening area between about 45 ° is limited to the perfect opening. The damper is arranged in the hearth housing and via a lever mechanism connected to the loading door. The lever mechanism includes an angle lever, of which an angle arm connected to the damper is via a swivel joint and the second angle arm is inserted into the door and by means of a releasably secured by a handle operated closure is.

In the electric cooker known from DE 44 43 098 A1 , a door is pivotally mounted about a horizontal axis on the device housing via a hinge. The hinge comprises a hinged band fastened to the housing and a bracket which is rotatably connected via a bolt to the hinge band and which is fastened from the inside to the appliance door, that is to say at the inner side thereof facing the charging opening of the electric cooker. Furthermore, a damping device is provided which damps the movement of the door during the opening and / or closing process.

In the known from DE 20 37 243 A1 door pivoting device for a domestic stove are hinged to the two narrow sides of the door support members which are connected to the pivotal mounting of the door on the device via two Hebelarmsysteme and a tension spring as a hinge to the housing of the device. The lever arms do not engage in the door, but are fastened from the outside.

The German Patent Auslegeschrift DE 1 779 221 discloses an aushängbare oven door for cookers, which is designed as a hollow body and in the interior of an approximately U-shaped guide rail is attached. On the inner wall of the door facing the frying space, a recess extending upwards in the longitudinal direction of the guide bar is provided. On the muffle frame a hinge is attached with a fixed bearing arm and a horizontally movable bearing arm. On the movable bearing arm, a door tension spring of the hinge engages directly. The two bearing arms are connected by a guide rail on which the Bratofentür with the guide bracket is attachable. The guide rail engages with a nose plugged door and under the action of the door spring in a recess in the guide bracket of the door, so that the guide rail hooked firmly in the door. On the movable bearing arm a securing bracket is arranged, which releases or blocks depending on the position acting on the bearing arm force of the door spring. The two bearing arms are guided through the recess in the inner wall.

The door hinge 2 according to FIG 1 to 4 has a first hinge part 3 and one on the first hinge part 3 via a Pivot pin 6 pivotally mounted about a pivot axis A. second hinge part 4 on. The minimum swing angle between the two hinge parts 3 and 4 is shown in FIG 1 and FIG 4 and designated αmin and is typically 90 ° or a few degrees less. A locking part 7 locks the second hinge part 4 in the position at αmin as shown in FIG 1. The maximum swing angle is shown in FIG 3 and denoted αmax and is typically 180 ° or a few degrees less. This swivel range will limited or fixed by stops. 2 shows a middle position with a swivel angle α, for the αmin ≤ α ≤ αmax holds. The direction of rotation represented by the arrow corresponds an increasing swing angle α.

As a second hinge part 4 is an elongated and level or flat trained hinge arm or hinge lever provided because of its sword-like shape also as a hinge sword or short sword can be called. The second hinge part 4 is formed largely linear and has a free from the first hinge part 3 free End 47, on an outer narrow side one essentially flat or planar outer surface 46 and on an inner Narrow side a complex with several stages designed Inner surface and two flat sides connecting the narrow sides Broadsides or flat sides on.

On the inside of the second hinge part 4 are from the free End 47 seen here first a locking projection 41, then a recessed relative to the locking projection 41 and parallel to the outer surface 46 extending contact surface 42, then one opposite the contact surface 42 set back again Clearance 43, then a stop projection 44 with a perpendicular to the contact surface 42 and the outer surface 46 to the Clearance 43 subsequent stop surface 45, then a towards the stop projection 44 set back again Arretierungsfläche 48 and finally a guide surface 49th arranged. The abutment surface 45 separates a first part 4A from a second part 4B of the second hinge part 4.

The stopper projection 44 projects further outward than the Detent projection 41 and serves as a stop when inserting the second hinge part 4 in a receptacle of a door, such as will be explained below. The guide surface 49 has a trapezoidal longitudinal section on three different inclined slopes, and serves as a guide for a just in FIG 4 illustrated torque device 5 in the first hinge part 3, as is also still running.

The first hinge part 3 comprises within an oblong and linearly formed hinge housing 30 a torque device 5, at least in certain pivoting positions generates a torque that reflects the rotational movement in counteracts the rotation shown in Figures 1 to 3, ie antiparallel is directed to the torque that is for pivoting the two hinge parts 3 and 4 against each other in the in FIG 1 to 3 must be expended.

The torque device 5 of the first hinge part 3 comprises in the example of FIG 4, a guide roller 52, the on the guide surface 49 of the second hinge part 4 rolls, a connected to the roller 52 U-shaped rocker 53 as Pressure lever, a coupled to the rocker 52 compression spring 51, which is supported in a pull lever 55 and then a tension spring 50, which at one end by a bolt with the Hinge housing 30 is connected and the other end in a bolt 55 is mounted in two slots 35th of the hinge housing 30 is movably guided. This further Pin 55 actuates the pull lever 55 of the opposite End over the pivot pin 6 as a pivotal connection with the second hinge part 4 about the pivot axis A pivotally connected is. When turning the second hinge part 4 and becomes larger opening angle or tilt angle α is the Tension spring 50 more and more stretched and exercises an ever larger expect elastic restoring force. This allows a torque, in particular the weight of a fastened to the hinge Door to be compensated when opening. The compression spring 51 is connected to the rocker 52 via a connecting rod and a bolt and acts on the (residual) tensile force of the tension spring 50 at small swivel angles α against. Tension spring 50 and compression spring 51 are each formed as a helical spring. The Rocker 52 presses with the roller 52 on the guide surface 49 the front edge of the second hinge part 4 and the roller 52nd rolls upon movement of the second hinge part 4 relative to first hinge part 3 via the guide surface 49 or contour or front edge of the second hinge part 4 from. From approx 120 ° arises when opening the hinge ever larger expectant air gap between roller 52 and guide surface 49th When closing the door hinge 2, the roller 42 presses against it over the last 30 degrees more and more against the Guide surface 49. Due to the trapezoidal contour of the guide surface 49 can now be e.g. a kind of open position of the door hinge 2 at α = 105 ° or reached and / or the Contact pressure of the door hinge and thus the door at Closing strengthened or reduced. This structure of Torque device 5 according to FIG 4 is in itself from the beginning mentioned known hinge in the Applicant's devices known. However, other mechanisms may be used become.
