Definitions
- the invention relates to a household appliance hinge, comprising a hinge arm for connection to a household appliance door, a hinge housing with two lateral Genzousewangen, which hinge arm is rotatably connected to the hinge housing at a first axis of rotation, and a friction device for inhibiting a movement of the hinge arm.
- the invention further relates to a household appliance with at least one such household appliance hinge.
- the invention is particularly advantageous applicable to household appliances that have an oven, for example, on stand-alone ovens or cookers.
- DE 10 2008 010 523 A1 discloses a domestic appliance device with a domestic appliance door and at least one domestic appliance door storage unit which supports the household appliance door pivotably about an axis. In order to achieve a coordinated mobility of the domestic appliance door, it is proposed that the domestic appliance device has at least one locking unit which is provided to fix the domestic appliance door storage unit in at least one pivot position.
- DE 199 23 994 A1 discloses a household appliance hinge device with locking surfaces, which hold the door in the horizontal open position against a spring door closing force, even if a glass plate of the door is removed for cleaning, but the holding force by a manual force on the door in the closing direction is surmountable.
- EP 1 961 901 B1 discloses a hinge for wings or doors, in particular of electrical appliances, comprising a first element and a second element, a lever for connecting the first and the second element, wherein the lever rotates on the second element by means of a pin which makes the first and second elements movable relative to one another with a tilting action, whereby one of the first and second elements can be fixed to one frame and the other to a wing or door, so that the wing or the door is relative to the frame between a closed position and an open position, the second element being box-shaped and containing elastic means connected to the lever by a rod which slides in the second box-shaped element, the hinge further comprising friction means for applying a braking action to the reciprocal sliding of the rod relative to the second box-shaped element, wherein the friction means comprise a friction member interposed between and connected to the rod and the second box-shaped member, the second
- EP 2 620 576 A2 discloses a hinge mechanism having a friction system in the interior used in oven doors. This friction system helps keep the door in a balanced position during opening and closing by means of the frictional force.
- a household appliance hinge comprising a hinge arm for connection to a household appliance door, a hinge housing with two lateral housing walls, which hinge arm is rotatably connected to the hinge housing at a first axis of rotation, and a friction device for inhibiting a movement of the hinge arm wherein the friction means comprises a variable-length component (hereinafter referred to as a "cartridge”) comprising a spring element for expansion, the cartridge being housed in the hinge housing between the two lateral housing walls, the cartridge being movable with the hinge arm and wherein the cartridge is pressed by means of the spring element against at least one of the two Gescousewangen.
- a variable-length component hereinafter referred to as a "cartridge”
- the cartridge being housed in the hinge housing between the two lateral housing walls, the cartridge being movable with the hinge arm and wherein the cartridge is pressed by means of the spring element against at least one of the two Gescousewangen.
- This household hinge has the advantage that it is particularly simple and compact to implement. Also, the cartridge is particularly durable. Despite wear of the cartridge on at least one housing cheek and despite component-related tolerances of the hinge (e.g., a hinge width of the hinge housing), a virtually unchanged braking effect and thus virtually constant stabilization of the household appliance door, in particular of its door leaf, can be achieved throughout the lifetime of the hinge.
- component-related tolerances of the hinge e.g., a hinge width of the hinge housing
- the household appliance hinge may in particular be a heavy-duty hinge with, for example, a load-bearing capacity of at least 150 N.
- the household appliance door may in particular be a horizontally pivotable or hinged door.
- the first axis of rotation can be aligned horizontally, so that the hinge arm is horizontally connected to the hinge housing rotatably.
- the hinge arm can be inserted or used for connection to a household appliance door, for example in an associated door leaf.
- the hinge housing may be a sheet metal part.
- the housing walls can in particular be aligned parallel to one another.
- the housing walls can be mirror-symmetrical to each other.
- the cartridge is variable in length, i.e., compressible (compressible) or elongatable.
- the cartridge has in particular an elongate shape with a corresponding longitudinal axis. It is advantageously length-adjustable along its longitudinal axis.
- the spring element causes the cartridge in a free state has a predetermined equilibrium length or free length and can be pressed against the spring element.
- the fact that the cartridge is mitbeweglich with the hinge arm may in particular include that the cartridge is connected directly to the hinge arm or at least one intermediate element - such as a deflector - with the hinge arm.
- the cartridge can be held positively and / or non-positively by the hinge arm or by the intermediate element at least in the direction of movement of the hinge arm.
- the movement of the hinge arm is thus converted into a movement of the cartridge.
- the movements of the hinge arm and the cartridge can lie in particular in the same - in particular vertical - plane.
- the deflector is slidably guidable in the hinge housing may include both that it is in a movement of the door in the hinge housing only slidably movable by means of the hinge arm, as well as that it is displaceably movable and additionally rotatable during a movement of the door in the hinge housing by means of the hinge arm.
- the deflecting bar can be a material part-in particular a piece of sheet metal-with two side parts, the two side parts being arranged at least approximately parallel to one another and spaced apart from one another. In particular, they can be mirror-symmetrical to one another. It is an embodiment that the cartridge is in particular simultaneously pressed against both lateral Gepurwangen.
- the cartridge between the two GeHousewangen is clamped.
- the cartridge is advantageously aligned perpendicularly to the two housing walls.
- the cartridge has a longitudinal extent which is perpendicular to a direction of movement of the cartridge. This can suppress a tilting of the cartridge particularly effective.
- the cartridge can be kept in particular in a horizontal position.
- the longitudinal extent may correspond to the longitudinal axis.
- the household appliance hinge has a deflecting bar rotatably connected to the hinge arm at a second axis of rotation, which is accommodated at least partially in the hinge housing and is displaceably guided there and which is designed as a driver for the cartridge.
- the working path corresponds to a path of movement of the cartridge between end positions corresponding to the end positions of the hinge arm and thus the door (closed position and fully open position). It is yet another embodiment that the cartridge undergoes a different longitudinal extent over its working path in the hinge housing. This provides the advantage that a frictional force can be dependent on a position of the cartridge on its working path and thus also dependent on an opening angle of the hinge arm and the door. This in turn allows a particularly effective coordination of the friction force, for example dependent on a leverage exerted by the door.
- the cheek distance at at least one end portion of the working path is greater than outside.
- At at least one of the two end portions of the working path of the cheek distance is so large that the cartridge takes or almost takes their equilibrium length or free length.
- the cheek distance can there so be at least as large or larger than the equilibrium length of the cartridge.
- the cheek areas on at least one end portion have an outwardly facing expression.
- a local increase in the cheek distance can be implemented in a simple manner.
- the expression can also be referred to as a bulge, bulge, etc.
- such characteristics can basically be introduced at any point on the way to work.
- the deflection handle has at least one hole for the particular horizontal passage of the cartridge.
- the deflector has two side parts, it may e.g. mirror-symmetrical holes into which the cartridge is inserted can be present to a vertical plane. This allows a cheap, easy to install and robust cartridge holder. A tilting of the cartridge even with large forces can be effectively prevented.
- the cartridge has two mutually sliding sleeves, in which the spring element is inserted in the form of a compression spring. The sleeves may for example be telescoped into each other. Such a structure is particularly easy to implement and stable. It is also an embodiment that the two sleeves are locked together. As a result, an assembly of the cartridge is facilitated because the sleeves then can not slip apart.
- the sleeves may be plastic sleeves, metal sleeves or ceramic sleeves.
- the sleeves can together form a cartridge with a cylindrical basic shape.
- the two sleeves have respective rounded end faces, which faces contact surfaces to the Gescousewangen dar- put. This gives the advantage that the sleeves can move particularly smoothly, in particular in terms of in and out again.
- the object is also achieved by a household appliance having a treatment room, which has a front-side charging opening, and a horizontal
- pivotable door for closing the loading opening which door is connected by hinges to the rest of the household appliance, the hinges are household appliances hinges as described above.
- the household appliance can be designed analogously to the household appliance hinge and has the same advantages.
- the household appliance has an oven, the treatment room is a furnace room and the door is a baking-oven door.
- the household appliance hinge is advantageously used, since oven doors are particularly heavy due to their thermal insulation and possibly ventilation structure.
- the household appliance hinge is attached to a frame of the household appliance, in particular left or right side next to the feed opening.

- the hinges 3 do not rest on their underside, so that they float freely are hung on the frame 1 1.
- the hinges 3 are slotted on their underside and hung there without support in a front plate 15.
- the missing support means referring again to FIG. 1 or FIG. 2, that the hinges 3 can oscillate about a vertical screw axis A (which is perpendicular to the first axis of rotation D1) fixed by the screws 14.
- FIG. 3 shows a side view of a sketch of the hinge 3 in its fully open position.
- the second axis of rotation D2 is arranged frontally in front of the first axis of rotation D1, and both axes of rotation D1 and D2 are arranged in front of the housing groove 6.

- the axle element 16 can have, for example, a rigid axle (for example a pin or bolt) and, on the end thereof, in each case a bushing and a securing ring (not shown).
- a rigid axle for example a pin or bolt
- the deflecting bar 5 In the fully open position, the deflecting bar 5 is on the axle 16 to stop in the housing groove 6, so that the hinge arm 7 a lever force on the first axis of rotation D1 or a pin 17 used there o. exercises.

- FIG. 4 shows a sketch of the household appliance door 2 in different angular positions or open positions, which is shown here relative to a vertical V. are.
- the deviation from the vertical V can be indicated by means of an opening angle ⁇ .
- the opening angle ⁇ has a value of minus 3 °.
- the door 2 may reach this first angular position P1 in a state built into the oven 1, or may be placed on a flange (for example, when the vertical V is reached).
- the door 2 can be intercepted or damped when closing it by means of so-called "soft-lock” mechanisms (not shown).
- the door 2 can be intercepted or damped when it is opened by means of so-called "soft open” mechanisms (not shown).
- the fourth angular position P4 may correspond to a completely open door 2.
- FIG. 5 shows a side view of the hinge 3 at an opening angle ⁇ of 10 °, in which a soft-close mechanism (not shown) can be effective.
- a soft-close mechanism (not shown) can be effective.
- the hinge 3 needs to take no or only a small damping and / or balance function.
- two housing walls 4a and 4b of the hinge housing 4 are each two outwardly facing forms 20a and 20b, which face each other mirror-symmetrically.
- a distance (“cheek distance") is locally increased as compared to an area between them.
- a displaceable between the forms 20a and 20b referred to as a "cartridge” 21 resilient friction device is present.
- the cartridge 21 is held and carried by the deflecting bracket 5 and rubs frictionally inside the housing walls 4a and 4b.
- Fig.6 shows the cartridge 21 in a side view.
- the cartridge 21 has a cylindrical basic shape with a longitudinal axis L, the end faces 22 - e.g. spherical - rounded off.
- the cartridge 21 is shown in its expanded or elongated state (e.g., with its equilibrium length) and compressible along its longitudinal axis L against a spring force, for example, about three millimeters.
- the cartridge 21 shows the cartridge 21 as a sectional view along a sectional plane B-B in plan view.
- the cartridge 21 consists of three components, namely a compression spring 23 and two plastic sleeves 24 and 25 latched together (here: clamped together) with respective rounded end faces 22.
- the material of the plastic sleeves 24 and 25 is sufficiently abrasion-resistant and rubbing selected.
- These two plastic sleeves 24 and 25 are mutually movable along the longitudinal axis L of the cartridge.
- a separation of the plastic sleeves 24 and 25 is prevented by means of an inner latch stop 26.
- By the pressure spring 23 therein they are pushed apart until reaching the latch hook stop 26.
- the length when reaching the catch stop 26 corresponds here to the equilibrium length.
- the cartridge 21 is inserted during assembly in at least one horizontal bore (not shown) of the Umlenkbügels 5 and then introduced 4 with the deflection bracket 5 in the hinge housing. If the deflecting bar 5 is mounted on the hinge housing 4, the cartridge 21 can slide rubbing between the two housing walls 4a and 4b of the hinge housing 4. The position of the cartridge 21 is dependent on the opening angle ⁇ of the door, since it is taken from the deflection bracket 5.
- the working path (also referred to as stroke) of the cartridge 21 there is a clamping portion in the middle corresponding to an opening angle ⁇ between 15 ° and 65 °, in which the cheek distance is less than in outer sections of the working path corresponding to an opening angle ⁇ of less than 15 ° or more than 65 °.
- the cheek distance in the middle clamping section can be narrowed by 3 mm, so that there the two plastic sleeves 24 and 25 are strongly compressed.
- the compression spring 23 in the cartridge 21 thus a force and friction and thereby a braking effect on the movement of the hinge 3 is exercised.
- the hinge 3 eg with respect to the hinge housing 4, the spring 19, etc.
- FIG. 9 shows a detail from FIG.
- the cartridge 21 In this open position, the cartridge 21 is located between the two forms 20b and, due to the increased cheek distance d, is comparatively elongated there. In particular, the cartridge 21 can be completely elongated there and consequently have its equilibrium length. Therefore, when the cartridge 21 is located between the two forms 20b, no or practically negligible pressure force is exerted by the cartridge 21 on the housing walls 4a and 4b. Therefore, a frictional force during movement of the cartridge 21 is small to negligible.
- the stay or commute of the cartridge 21 between the two forms 20b corresponds to an angular range of the opening angle ⁇ of the door 2 between about -3 ° and 15 °. In this angular range, the cartridge 21 thus exerts virtually no effect on a movement of the door 2.
- Fig.10 shows a side view of the hinge 3 at an opening angle ⁇ of the door 2 of 45 °. In this open position, neither a soft-close mechanism nor a soft-open mechanism work.
- FIG. 1 shows the hinge 3 at an opening angle ⁇ of 45 ° as a sectional view in plan view.
- FIG. 12 shows a detail from FIG. 1 in the region of the cartridge 21 and the characteristics 20a and 20b.
- the deflecting bracket 5 in the hinge housing se 4 forward in the position shown has been moved.
- the deflection bracket 5 takes the cartridge 21, which thus also moves between the housing walls 4a and 4b of the hinge housing 4 to the front. In this case, the cartridge 21 is extruded from the forms 20b. Because the cheek distance d in the working path of the cartridge 21 outside the forms 20a and 20b is less than at the forms 20a and 20b, the cartridge is compressed accordingly.
- the cheek distance d outside the forms 20 a and 20 b is dimensioned so that the cartridge 21 is almost completely compressed there.
- a high contact pressure is exerted on the housing walls 4a and 4b that, in order to entrain the cartridge 21 through the deflecting bracket 5, a noticeable frictional force is produced between the cartridge 21 and the cartridge
- the frictional force (in particular static friction force) is in particular so high that in a range of the opening angle ⁇ between 15 ° and 65 ° at least in sections an equilibrium state is reached at which a standing door 2 does not automatically close again or open further.
- a smooth sliding out of the cartridge from the forms 20 a and 20 b is facilitated by the rounded end faces 22.
- FIG. 13 shows a side view of the hinge at an opening angle ⁇ of 70 °. In this open position acts an unillustrated soft-close mechanism.
- Fig.14 shows the hinge in the open position of 70 ° as a sectional view in plan view.
- FIG. 15 shows a detail from FIG. 14 in the region of the cartridge 21 and the characteristics 20a and 20b.
- the spring element 19 is connected via a ram 30 serving for force transmission, which is rotatably connected to the deflection bracket 25.
- first to fourth angular positions P1 and P4 can also assume other values. Further, no or only a pair of the forms 20a or 20b may be present.
