EP3658824B1 - Cooking appliance comprising a lowerable door, which has a specific retaining spring for a bearing bush - Google Patents

Description

The invention relates to a cooking appliance with a housing in which a cooking space is formed. The cooking appliance has a door for closing the cooking space. The door is movably arranged on the housing. A handle on the door is stationary and therefore immovable. The cooking appliance has a storage space that is separate from the cooking space and is formed in the housing, into which the door can be retracted in its open state. The storage space has at least one guide track in which a guide element of the door is guided.

From the US 2,925,081 A a cooking appliance with a retractable door is known. In addition, from the DE 10 2007 041 891 A1 a door for a household appliance known.

In the case of cooking appliances, it is known that a door for closing a cooking chamber is arranged recessed in such a storage space when it is open. This enables a space-saving concept that allows unrestricted and close access to the cooking chamber at the front. In contrast to a folding door, which is only pivotally arranged on the housing, with such a retractable door it is possible to get very close to the cooking space when it is open. This simplifies handling for loading the cooking space or removing objects from the cooking space. This also minimizes bumping into an open door, so that unwanted heat effects on a user are avoided.

Such retractable doors for cooking appliances are known from the prior art. In this context, it is also known that such doors also have a handle that is movably arranged on the door itself. This is then done in such a way that when the door is pivoted and lowered into the storage space, the handle is also pivoted relative to a door leaf on which the handle is arranged. As a result, in the fully opened state, in which the door leaf is essentially oriented in a horizontal plane, the door handle is pivoted so that it can be gripped at the front. In order to enable such additional pivoting of the handle, are relative to form complex mechanical devices. This requires additional installation space and increases the weight of the door. Such a configuration is, for example, from EP 2 093 492 A2 known.

In order to counteract this, in alternative designs it can be provided that this handle is arranged in a stationary and therefore immovable manner on the door leaf. This means that when the door and thus also the door leaf are pivoted, this handle is not pivoted itself. Such a configuration is, for example, from DE 1 274 306 known. A disadvantage of this design there is that the door is permanently installed and is virtually impossible to remove. This makes maintenance work and cleaning more difficult.

It is the object of the present invention to create a cooking appliance which has a door which can be retracted into a storage space and has a handle which is arranged in a stationary manner on a door leaf, with the handling of the door being simplified as a separate component. This task is solved by a cooking appliance which has the features according to claim 1.

According to one aspect of the invention, a cooking appliance is provided with a housing in which a cooking space is formed. The cooking appliance has a door for closing the cooking space. This door is movably arranged on the housing. A handle on the door is stationary and therefore immovable. This means in particular that when the door moves, the handle does not move relative to the door leaf on which the handle is arranged. In addition, the cooking appliance has a storage space that is separate from the cooking space and is formed in the housing, into which the door can be retracted when open. The storage space has at least one guide track in which a guide element of the door is guided. As a result, in particular the movement of the door into and out of the storage space is predetermined in a very defined manner, so that this can be done very easily and without jamming or jerking.

The guide element is movably mounted on the door and connected directly to a first end of a retaining spring of the door. This retaining spring maintains a coupling position of the guide element on the door. Such a design makes it easy for the door to be reversible, non-destructively and easily and quickly Housing can be dismantled and reassembled. In order to be able to do this easily and safely, a defined coupling position of the guide element is required. However, since this guide element should also be movably mounted, this defined coupling position is required to mount the door on the housing. In order not to undesirably adjust this coupling position due to the movable mounting or not to find it in the first place, this coupling position is held with the specific holding element, namely in particular the retaining spring. The retaining spring in particular is a particularly advantageous component because, on the one hand, this coupling position is held securely, and on the other hand, there is a very continuous possibility of movement of this guide element, which is also predetermined by the spring. On the other hand, the retaining spring also makes it possible to reach this position automatically when this coupling position is left after assembly, since the retaining spring automatically sets the coupling position again due to the pretension it then achieves when dismantling. The specific connection of the retaining spring also provides a mechanically stable and component-minimised coupling mechanism.

According to the invention it is provided that the guide element has an integrated adjustment pin, by actuation of which the door can be released from a mounted state from a receptacle which is arranged on the guide track. It is precisely this adjustment pin that must be held in the assembly position, in particular by the retaining spring, in order to enable the door to be mounted on the housing. After assembly, this adjustment pin is then in a holding position that is different from its assembly position, so that the door is prevented from undesirably coming loose or falling off on its own from the housing. The adjusting pin is arranged at the end of the guide element and is oriented in a freely cantilevered manner.

It is preferably provided that the door has a bracket for holding a door pane of the door. A second end of the retaining spring is connected directly to this retaining bracket. This is also a mechanically stable, component-reduced design. In addition, this bracket, which is then present anyway, is a multifunctional component which is designed to hold the door window on the one hand and to hold the second end of the retaining spring on the other hand.

Preferably, the first end of the retaining spring is designed as a hook and is arranged to engage in a passage in a radial web of the guide element. This enables a particularly secure and simple mechanical coupling of the retaining spring directly to the guide element.

In particular, the retaining spring is a spiral spring.

In an advantageous embodiment, the feedthrough is designed as a keyhole-like geometry. On the one hand, this makes threading this first end of the retaining spring into the bushing very easy and accurate. On the other hand, this also ensures that in the final position, in which this first end is suspended in the tapered part of the keyhole geometry, there is as little play as possible and thus movement tolerance for this first end. This prevents the spring from slipping and making unwanted noise when the door is moved. In particular, this prevents the retaining spring from jumping undesirably in these movement scenarios.

It is preferably provided that a damping element for damping a friction noise between the retaining spring and the bushing is arranged on a boundary wall of the bushing. On the one hand, this also enables smooth movement and, in particular, particularly advantageously achieves particularly noise-reduced mounting of the retaining spring.

In a further advantageous embodiment it is provided that the retaining spring is surrounded by a tube-like casing. This cover is in particular a noise reduction element. Noises that occur when the retaining spring is tightened and relaxed are at least strongly dampened by this covering, so that no unwanted noises escape from the outside or are perceived as undesirably strong. This tube-like casing is preferably designed to be elastically deformable and can, for example, be a tube made of an elastomer.

It can be provided that the length of this casing, which is measured in the direction of its longitudinal axis, corresponds to the length that corresponds to the mouth area or corresponds to the axial extent of the spiral windings of the retaining spring when the retaining spring is in the unstressed state. This means that when the spring is tensioned and thus pulled apart, this area with the spiral turns becomes longer than the length of this sheath. On the one hand, this does not restrict the movement of the retaining spring, but on the other hand, this length of the casing is sufficient to sufficiently reduce noise.

However, in a further embodiment it can also be provided that the length of the casing is greater. This can be advantageous in particular if the casing is not rigid in length but is designed to be variable in length. For example, in such an embodiment, the casing can be designed as a bellows. With such a design, the change in length of the spiral spring area of the retaining spring can then also be carried out by this cover.

In an advantageous embodiment, the guide element is designed as a bearing bush. In the case of a design as a bearing bush, this then couples in particular directly with limiting elements of the guideway. It can thus be provided that the bearing bush has a guide groove into which a guide wall or a guide runner of the guide track engages. The design as a bushing is also designed in particular in such a way that a hollow area is formed with which this bearing bushing can then be plugged onto a coupling element such as a coupling rod, for example. In particular, this receptacle is designed as a blind hole. The bearing bush is therefore not a tubular component, but is closed at one end.

According to the invention it is provided that the adjustment pin is designed like a bar and is arranged with its longitudinal axis in the coupling position or assembly position at an angle between 10° and 40° to a vertical axis of the door. This specific coupling position or assembly position makes it possible to attach the door to the housing easily, quickly and safely, and the assembly processes or assembly movements can be easily and intuitively understood. This means that the assembly process of the door on the housing can be carried out easily, quickly and safely.

It is preferably provided that the door has an upper, hood-like cover strip. This cover strip is a separate part and can also be used as a top panel be referred to. The cover strip is in particular formed in one piece, in particular made of plastic.

In a further advantageous embodiment, the door has a pane package which has at least one front pane and one inner pane. The front window is the outermost pane of this pane package facing away from the cooking space. In particular, such a windshield is designed in such a way that, when installed, it covers the above-mentioned cover strip on the front. The surface area and the positioning of this front window are therefore chosen such that this cover strip, which is located behind it when viewed in the depth direction of the cooking appliance, is covered on the front. This also provides protection for this cover strip and enables the door to have a calmer appearance on the front.

An embodiment can also be provided in which the cover strip is not covered by the front windshield.

In a further advantageous embodiment it is provided that the cover strip has a separate stiffening part for stiffening the cover strip. This is advantageous in that in a cooking appliance which has a pyrolysis mode, an undesirable deformation of this cover element or this cover strip, which is in particular made of plastic, is avoided in this pyrolysis mode. Especially when a user pulls on the door with relatively great force during such a pyrolysis operation, this can lead to undesirable deformations of this cover strip, which is then avoided by this at least one additional stiffening part. The stiffening part can be arranged on the windshield and then the cover strip can be pushed or plugged onto it. In particular, a screw connection to the windshield is also provided here.

In an advantageous embodiment it is provided that this stiffening part also has the function of a locking element with which the door is locked in its closed position during the pyrolysis operation of the cooking appliance.

Preferably, at least one stop is formed in the storage space, which limits the immersion depth of the door in this storage space in such a way that the handle is in the maximum insertion position Door is positioned at a distance from a front side of the cooking appliance. In particular, it is provided that in this maximum insertion position between a front side of the housing and an upper edge of the door, which does not have to be the same as the upper edge of the handle, since the handle can also be arranged at a downward distance from the upper edge of the door in this respect, between 80 mm and 90 mm, in particular 85 mm.

In an advantageous embodiment it is provided that the door is designed in such a way that different front panes of the above-mentioned pane package can be mounted. In particular, differently colored glasses can be used, so that different variants can be created with regard to the front optical appearance. This makes it possible to create a uniform visual front appearance with an optionally additional switch panel or control panel of the cooking appliance, which is preferably arranged adjacent to the door.

It is also possible for a cover strip with at least two different variants to be mounted on the door. A cover strip can be provided for a cooking appliance that has a pyrolysis operation. However, a different cover strip can also be provided, which is suitable for a cooking appliance that does not have pyrolysis operation. In particular, identical components are provided in this context, which enable this connection of cover strip variants.

The handle of the door is preferably attached to the windshield, in particular screwed on. For this purpose, the windshield preferably has two guides or holes through which the screws can be passed. It is preferably provided that the stiffening part, which can be arranged on the cover strip in order to stiffen it, is also screwed to the windshield. In particular, it can be provided that the screw connection takes place via the screw hole to which the handle is also screwed. This means that stops are limited locally and the number of bushings or screw holes in the windshield is minimized.

In one embodiment it can be provided that the guide element is formed in one piece. The guide element can preferably be made of plastic.

In the figures, identical or functionally identical elements are given the same reference numerals.

In Fig. 1 a cooking appliance 1 is shown, which can be, for example, an oven or a microwave cooking appliance or a steam cooking appliance or a combination of the devices mentioned. The cooking appliance 1 has a housing 2 in which a cooking chamber 3 is designed for cooking food. The cooking appliance 1 also has a door 4 which is designed to close the cooking chamber 3 at the front. The door 4 has a door leaf 5, which is designed as a plate-like part. A handle 6 is arranged on the front of the door leaf 5 and thus facing away from the cooking space 3. This handle 6 is stationary and therefore immovable on the door leaf 5, in particular screwed on. Door 4 is in Fig. 1 shown in the closed state. In this embodiment, the door leaf 5 is then oriented in a vertical plane, namely the xy plane.

The cooking appliance 1 also has a storage space 7, which is designed separately from the cooking space 3 and is formed in the height direction (y direction) below the cooking space 3 in the housing 2. The door 4 can be inserted or sunk into this storage space 7 when open. Even when the door 4 is moved, the position of the handle 6 on the door leaf 5 does not change relative to the door leaf 5.

In the exemplary embodiment, the cooking appliance 1 also has a control panel 8, on which an operating and/or display device 9 is preferably formed.

The storage space 7 is delimited by walls, with two opposite side walls in particular each having a guide track 10 and 11 in which guide elements of the door 4 are guided.

In Fig. 2 an embodiment of the door 4 is shown in an exploded view. It is envisaged that the plate-like door leaf 5 has a pane pack 12, the pane pack 12 having a front pane 13, an inner pane 14 and here in particular also an intermediate pane 15. These three disks 13 to 15 are arranged in particular parallel and spaced apart from one another. The door 4 also has a cover strip 16, which is designed as a hood or top panel placed on top. This cover strip 16 is preferably made in one piece and in particular made of plastic. It covers the door leaf 5 from above.

The door 4 also has a frame 17, which is designed here in several parts and on which the pane package 12 is held.

In addition, the door 4 has the guide elements already mentioned, which are designed here as bearing bushes 18, 19. The two bearing bushes in the exemplary embodiment are positioned at opposite ends in the width direction of the door and are preferably connected by a connecting rod 20. The bearing bushes 18 and 19 are pushed onto this connecting rod 20 on the narrow side. One of the bearing bushes 18, 19 is then arranged to engage in the guide tracks 10, 11, so that the lowering movement or the moving out of the door 4 into the storage space 7 or out of the storage space 7 is guided and thus takes place particularly smoothly and without spreading.

The bearing bushes 18 and 19 are also held by holes 21 and 22 which are formed in frame parts or frame profiles of the frame 17.

As can also be seen, a plurality of brackets 23, which represent adhesive angles, are arranged on an inside 13a of the windshield 13.

In addition, it can be seen that in the windshield 13 here two bushings 24 and 25 are designed as screw holes through which screws can be passed in order in particular to be able to attach the handle 6 in a stationary manner to the windshield 13.

As in Fig. 1 can be seen and in Fig. 2 is indicated, the front window 13 has a height (extension in the y-direction), so that the cover strip 16 is covered by this front window 13 when the door 4 is viewed from the front, in particular is completely covered.

In Fig. 3 Partial components of the cooking appliance 1 are shown, with the door 4 being shown here in a partially open state, but not yet retracted into the storage space 7.

This is in Fig. 4 a representation is shown in which this door 4 is completely open and sunk into the storage space 7.

As already in Fig. 4 As can be seen, the door 4 and in particular the door leaf 5 protrudes forward from the storage space 7 with a specific length in this maximum insertion position. The maximum immersion depth of the door 4 and in particular of the door leaf 5 in this end position is such that between a front side 26 of the housing 2 and an upper edge 27 of the door 4, in particular of the door leaf 5, there is a distance a between 80 mm and 90 mm, in particular 85 mm. This maximum The immersion depth and thus the distance a are selected so that the handle 6 is positioned at a distance from the front side 26 in this depth direction for reaching behind with one hand, as shown in Fig. 5 can be recognized. Like beyond that in Fig. 5 Also shown, a stop 28 is arranged in the storage space 7, which limits this maximum insertion depth of the door 4.

In Fig. 6 the door 4 is shown in the assembled state. The door 4 is shown here with a view of the inner pane 14.

The bearing bushes 18 and 19 are movably arranged on the door 4 so that they can rotate about the axis, which is oriented in the width direction (x-direction) and is specified in particular by the connecting rod 20. In this context, a relative movement to the door leaf 5 is therefore possible.

If a specific coupling position or coupling position, which is a mounting position, of the bearing bushes 18 and 19 is set, the door 4 can be mounted on the housing 2. However, this coupling position of the bearing bushes 18, 19, which is a specific rotational position about this axis of rotation, must first be set and specifically maintained in this regard.

The door 4 points to this, as shown in an enlarged view in Fig. 7 can be seen improved, a retaining spring 29. The in Fig. 7 shown enlarged area I in Fig. 6 shows that this retaining spring 29 is connected directly to the bearing bush 19 with a first end 29a, which is bent in a hook shape.

In the embodiment shown here, the bearing bush 19 has a radial web 30 which has a passage 31 in the form of a hole through which this first end 29a is passed and suspended. This radial web 30 also represents a boundary of a groove 32. On the other hand, the groove 32 is limited by a further radial web 33. With this groove 32 there is a coupling with a guide skid of the guide track 11, this guide skid engaging in the groove 32.

In addition, the retaining spring 29, which is in particular a spiral spring, is directly connected to a retaining bracket 23 with a second end 29b opposite the first end 29a. which is provided for holding the windshield 13 and is glued to this windshield 13.

In addition, the door 4 has a tube-like cover 34 which surrounds the retaining spring 29. In the axial direction, this sleeve 34 has a length which corresponds to the area with the spiral turns of the retaining spring 29 when the retaining spring 29 is in the relaxed state. In Fig. 7 In contrast, the tensioned state is shown in which these turns are pulled apart. As a result, only a portion of these spiral turns is surrounded by this tube-like cover 34. The tubular cover 34 represents a noise reduction element. It can be made of an elastic material, for example elastomer.

The above-mentioned coupling position of the guide element 29 is held in position by the retaining spring 29. In addition, this retaining spring 29 also ensures that when the bearing bush 19 is pivoted out of this coupling position in the assembled state, this coupling position is automatically set again when the door 4 is subsequently dismantled from the housing 2.

In a further embodiment according to Fig. 7 It can also be provided that this cover 34 is not stable in length, but is designed to be variable in length and can be, for example, a bellows. In such a configuration, this casing 34 can then carry out the change in length of the spiral region of the retaining spring 29, so that even in the tensioned state of the retaining spring 29, the spiral winding region is in particular completely surrounded by the casing 34.

On the opposite side of the bearing bush 18, the door 4 is preferably designed accordingly.

In Fig. 8 an enlarged view of a side view of the door 4 is shown, looking here at an outer end of the bearing bush 19. As can be seen here, this bearing bush 19 has an integrated adjustment pin 35, which is designed like a bar and is exposed or oriented in a cantilevered manner on the side. The door leaf 5 has a vertical axis H, which is oriented in the height direction when the door 4 is closed. In contrast, this bar-like adjustment pin 35 has a Longitudinal axis K is arranged inclined thereto, whereby an angle α can be between 10° and 40°, in particular between 10° and 30°. In Fig. 8 In this context, the coupling position of the bearing bush 19 and thus also of the adjusting pin 35 already mentioned above is shown.

In Fig. 9 an enlarged view of an exemplary embodiment of the bearing bush 19 is shown. It can also be seen here that the feedthrough 31 has the shape of a keyhole or the type of keyhole geometry. As can be seen here, an area 31a facing the longitudinal axis L of this bearing bush 19 is widened to enable easy insertion of the end 29a. In contrast, a further region 31b of this passage 31, which is radially spaced from it and is therefore further outward from the longitudinal axis L, is tapered. In the final assembled state, the hook-shaped end 29a is mounted in this tapered area 31b. It can be provided that boundary walls of this bushing 31 are covered with a noise-reducing material, for example a sealing element or a corresponding coating is attached. For this purpose, for example, this hanging eyelet can be covered with a plastic jacket or a sealing ring can be arranged on this boundary wall.

In Fig. 10 A further section of the door 4 is shown in a perspective view, with an upper corner area with the cover strip 16 being shown here. A separate stiffening element 36 can be arranged on this cover strip 16, in particular can be attached. This stiffening part 36 can be made of metal. It serves in particular in the pyrolysis mode of the cooking appliance 1 to stiffen the cover strip 16 made of plastic, so that it is not undesirably deformed, especially when it is pulled. This stiffening part 36 is preferably screwed to the windshield 13, with a passage 37 being provided for a screw here. In particular, the bushing 37 is then congruent with the bushing 25, so that the same screw connection as for the handle 6 is also provided for this stiffening part 36. The stiffening part 36 can also serve as a locking element for locking the door 4 in pyrolysis operation.

In Fig. 11 a side view of the bearing bush 19 is shown. The geometry of the implementation 31 is shown in more detail here. Furthermore, in this example wing-like stops 38, 39 are formed, which are axially oriented and arranged at a radial distance from a base tube of the bearing bush 19. These stops 38, 39 prevent a safety spring 40 from jumping out, with which the position of the bearing bush 19 on the connecting rod 20 is secured. The safety spring 40 is shown in perspective Fig. 12 shown. The securing spring 40, designed as a wire spring, engages with a bracket area in an opening 41 in the base tube of the bearing bush 19. This bracket area extends through the wall of the base tube in order to mechanically couple to the connecting rod 20 and secure the position.
