A household cooking appliance has a steam cooking appliance (5) and, in addition, another cooking appliance (2) arranged separately from it, which has a stationary cooking chamber (2a) that can be closed with a door (3). The invention can be applied particularly advantageously to multi-cavity household appliances with an oven arranged above the steam cooking appliance.

Description

The invention relates to a steam cooking appliance, having a drawer housing and a steam treatment drawer that can be moved horizontally into the drawer housing. The invention also relates to a household cooking appliance, having a steam cooking appliance and, in addition, another cooking appliance arranged separately therefrom, which has a stationary cooking chamber that can be closed with a door. The invention can be applied particularly advantageously to multi-cavity household appliances with an oven arranged above the steam cooking appliance.

There are known double ovens with two separate stationary oven chambers, each of which can be closed with a front oven door and can be heated by means of resistance heaters. One of the furnace rooms can also be used as a warming compartment.

Also known are double ovens with two separate oven chambers that can be heated by means of bottom and top heat resistance heaters. One of the two furnace chambers is designed as a drawer.

Also known are household cooking appliances with a stationary oven space that can be closed by a front oven door and a stationary steam treatment space that is arranged separately from it and can be closed by its own front oven door.

Also known are household cooking appliances with an oven in which a cooking chamber divider can be used to thermally separate the oven chamber into two sub-chambers. The two sub-rooms can be heated separately. A cooking utensil consisting of a pot and a lid can be pushed into one of the partial spaces, with the cooking utensil having a steam connection for connection to an evaporator present outside the oven space.

Also known are oven/steamer drawer combinations in which a steamer drawer is located below an oven. A loading opening on the upper side of the damper pan can be covered by means of a pivotable cover. The disadvantage here is that the steam treatment drawer can collide with an open oven door when the lid is folded up, which can lead to damage to the lid and/or the oven door. In addition, such steam treatment drawers are difficult to clean thoroughly.

It is the object of the present invention to at least partially overcome the disadvantages of the prior art and in particular to provide a particularly user-friendly option for covering a damper pan of a steam treatment drawer.

This object is solved according to the features of the independent claims. Preferred embodiments can be found in particular in the dependent claims.

• - einen Tragrahmen, der über ein Auszugssystem mit der Dampfbehandlungsschublade verbunden ist, der eine Dämpferwannenaufnahme zur Aufnahme mindestens einer Dämpferwanne aufweist und in dem ein Verdampfer untergebracht ist und
• - einen auf dem Tragrahmen verschieblich aufsetzbaren Deckel, welcher mindestens einen Vorsprung („Zapfen“) aufweist, der bei ausgefahrener Dampfbehandlungsschublade und zumindest teilgeöffnetem Deckel auf einer Führungsschiene des Schubladengehäuses verfahrbar aufliegt.

The object is achieved by a steam cooking appliance having a drawer housing and a steam treatment drawer that can be moved horizontally into the drawer housing, the steam treatment drawer having:

• - A support frame, which is connected to the steam treatment drawer via a pull-out system, which has a damper pan receptacle for receiving at least one damper pan and in which an evaporator is housed and
• - A cover that can be slidably placed on the support frame and has at least one projection ("pin") that rests on a guide rail of the drawer housing so that it can move when the steam treatment drawer is extended and the cover is at least partially open.

Compared to a hinged lid, the sliding lid has the advantage that, when open, it cannot collide with objects located above the steam cooking appliance, such as an open oven door of an oven arranged above it. In addition, a particularly high-quality impression is achieved. In addition, a particularly good use of space is advantageously achieved, in particular a particularly large steam treatment space is made possible. Another advantage, especially in comparison to a hinged lid, is that the material thickness of the lid can be particularly small since it does not have to be designed for mechanical resistance to slamming shut. In addition, the sliding cover can be safely pushed into the drawer housing without the risk of it tipping open and/or falling into the drawer housing.

The steamer is used in particular to treat items to be cooked with steam. The steamer can be a pure steamer or can additionally have at least one other cooking device such as at least one heat radiator (e.g. at least one electric resistance heater), a microwave generator, etc. and thus be a combination cooking device. The food to be cooked can be, for example, but not limited to, food or dishes.

It is a development that the steamer is a household appliance.

The steam treatment drawer can be moved horizontally into the drawer housing from the front and pulled out again, e.g. manually, motor-assisted or fully motorized, e.g. purely manually using a handle, using a push-to-open mechanism, etc. The pull-out system can be a telescopic pull-out system, for example.

The support frame provides a damper tray mount for receiving at least one damper tray. The damper tray mount is designed to accommodate one or more damper trays, in particular by inserting it from above. In particular, the damper trays can be removed from the damper tray mount by the user, which makes loading and cleaning them easier. A steamer trough is provided to accommodate the food to be cooked and/or food inserts for steam treatment. It is a further development that the damper tray mount and the at least one damper tray have GN-compliant dimensions.

The evaporator arranged in the support frame is used to convert water into steam, the steam being conducted into the at least one steamer trough during a steam treatment process in order to steam-treat the food to be cooked located there. The steam can be wet steam or superheated steam.

It is an advantageous development for a compact structure that the evaporator has a steam generation unit and a water tank as components. It is an advantageous development for easy emptying and cleaning, in particular decalcification, that the steam generation unit and/or the water tank are designed to be removable individually and/or together from the support frame. It is particularly advantageous if the water tank can be inserted into and removed from a receiving recess on the upper side of the steam generating unit by the user. Alternatively, the water tank is arranged and can be handled separately from the steam generation unit. The steam generating unit is set up to boil water supplied from the water tank and thereby generate steam. For this purpose, the steam generating unit has at least one heating element—advantageously arranged on the bottom side. In a further development, the at least one heating element is an electrically operated heating element. It is a particularly advantageous development for removing the steam generation unit that the heating element can be heated, for example, by thermal radiation, contact heat or induction. In this case, the heating element is not operated directly electrically, but is (indirectly) heated by a heating unit such as a resistance heater or induction coil that is permanently installed in the steam treatment drawer. The water tank is intended to refill water into the steam generating unit. There may be a valve between the steam generating unit and the water tank to regulate the flow of water.

In particular, the evaporator can be arranged in a section of the steam treatment drawer or of the support frame that is located in front of the steamer tray receptacle (when viewed from the front).

In its closed position, the lid is used to at least largely cover the open top or loading opening of the steamer pan in a steam-tight manner, so that the lid and the steamer pan provide a steam treatment space for the food to be steamed. For this purpose there can be at least one seal between the cover and the damper pan, which can be attached to the damper pan and/or to the cover disc. For steam inlet into the steam treatment chamber, it can be fluidically connected to a steam outlet of the evaporator, e.g. through an opening in the damper pan. The lid can be moved or shifted manually from the closed position to a fully open position and to any intermediate position (“opening the lid”) and vice versa (“closing the lid”). In particular, the damper pan can be removed from its receptacle when the lid is in its fully open position. When the steam treatment drawer is extended, the cover dips into the drawer housing in sections when it is partially or fully open.

The cover is guided in the drawer housing by the at least one pin, which enables it to be safely pushed into the drawer housing without the risk of it tipping up and/or falling into the drawer housing.

The fact that the cover rests movably on at least one guide rail of the drawer housing when the cover is at least partially open means that the cover rests on at least one guide rail in a partially open state and in a fully open state. This can include the lid not yet resting on the at least one guide rail for a certain distance when it is opened from its closed state, but only then moving onto the guide rail.

It is an embodiment that (in a front view) a T-shaped pin piece protrudes from the cover, in particular in the middle, the crossbar of which has a pin protruding on the left and a pin protruding on the right. Furthermore, a guide rail is arranged in particular in the center of the drawer housing (in a spatial area which is located above the lid when the drawer is retracted), which has a slot on the underside which separates a left-hand running surface from a right-hand running surface, and when the lid is at least partially open, a vertically protruding one Leg section of the pin piece emerges through the slot and the pin rests movable on the corresponding running surfaces of the guide rail. In this way, the advantage is achieved that the steam treatment space can be made particularly wide.

The leg section is aligned vertically, while the crossbar and thus the two pins are aligned particularly horizontally at its upper end or extend horizontally in opposite directions. The guide rail is aligned in the direction of movement of the drawer, i.e. it runs from front to back when viewed from the front. In particular, it is open at the front or at the front in order to make it easier to insert or immerse the spigot piece. When the lid is opened, the pin piece is inserted into the guide rail at the front, with the vertical leg section entering the slot. The two pins rest on the left-hand running surface and on the right-hand running surface.

In a further development, the guide rail is a tubular guide rail. It can, for example, have a rectangular cross-sectional shape with a central recess in an underside, for example, for forming the slot.

In one configuration, the front side of the guide rail is funnel-shaped. This advantageously supports reliable retraction of the spigot piece into the guide rail and the spigot resting on the respective running surface when the cover is opened.

An alternative embodiment is that the cover has a pin protruding on the left (e.g. from a left edge) which, when the cover is at least partially open, rests movably on a guide rail located in the area of a left side wall of the drawer housing, and a pin on the right (e.g. from a right edge) protruding pin, which rests movably on a guide rail located in the area of a right-hand side wall of the drawer housing when the cover is at least partially open. In this way, the advantage is achieved that the steam treatment space can be designed to be particularly high. In addition, this configuration can be implemented in a structurally particularly simple and cost-effective manner. The guide rails run from front to back on an inside of the drawer housing. It is a further development that the guide rails are designed as angle profiles (“guide angles”).

In one configuration, the at least one pin is designed as a sliding pin. Advantageously, this is particularly reliable and cost-effective with little wear at the same time.

In one configuration, the at least one journal is designed as a roller, cylinder or wheel or has a roller, cylinder or wheel. As a result, a particularly low resistance to the cover moving backwards and forwards is advantageously achieved, which improves user haptics.

In one configuration, the cover has a glass pane or is made of glass, in particular transparent glass, at least in certain areas. Glass has the advantage that it is highly resistant to hot water, steam and vapors and is also much more abrasion-resistant than plastic. It is a further development that the glass pane is printed, e.g. with decorative strips on the side.

In one embodiment, the cover has a mounting part or end piece made of plastic that is attached to the front side of the glass pane. This advantageously makes it easier to equip the cover with functional elements. It is a further development that the mount part attached to the front (also simply referred to as the front mount part) extends over the same width as the glass pane.

In one embodiment, the front mounting part has a grip area that is accessible from the top, with the aid of which a user can advantageously handle, in particular move, the cover easily and safely. The handle area can be, for example, a handle that protrudes upwards or a handle shell.

In one embodiment, the front mounting part has a downwardly protruding projection (“guide skid”) on the left and right, which at least partially runs on raceways formed in or on the side cheeks of the support frame when the cover is moved. This achieves the advantage that a course of movement of the cover when opening and closing can be adjusted in a particularly well-defined manner. This configuration represents an independently inventive idea that, in combination with the min least one pin, however, is particularly advantageous. The object can therefore also be achieved independently by a steam cooking appliance having a drawer housing and a steam treatment drawer that can be moved horizontally into the drawer housing, the steam treatment drawer having at least one support frame which is connected to the steam treatment drawer via a pull-out system and has a steamer tray receptacle for receiving at least one steamer tray and in which an evaporator is accommodated and has a cover that can be slidably placed on the support frame, the cover having a socket part or end piece made of plastic that attaches to the front side of the glass pane, and the front socket part has a downwardly protruding guide skid on the left and right side, which, when the cover is moved, run at least in sections on raceways formed in or on the lateral cheeks of the support frame.

It is a further development that the guide runners are designed as skids, which allows the advantage of a structurally particularly simple and also cost-effective implementation. In a further development, the guide skids have rollers, wheels or rollers, which has the advantage that the cover can be moved particularly easily by the user.

In one embodiment, the running tracks are designed as first guide links on their front-side sections, which initially run at least approximately horizontally in the direction from the front to the rear and then have a step that rises to the rear. In this way, the advantage is achieved that a user can initially slide the lid from its closed state onto the horizontal track section with little resistance, preferably by a comparatively small safety distance of, for example, approximately 20 mm. The following level causes increased resistance to pushing the lid open further and is clearly noticeable haptically. It is thus made easy for a user to slide open the lid until the stage is reached. This initial sliding causes a gap to form between the front edge of the cover and the steamer pan, through which steam still present in the steam treatment chamber after a steam treatment process can escape in a targeted manner.

A further development that is advantageous for protecting a user's hand is that a front edge of the lid is designed in the shape of a groove on the underside, since the steam then escapes from the grooves after the lid has been opened a little bit, so that the steam escapes less directed upwards, but more forward. This, in turn, reduces the likelihood of the hot steam hitting a user's hand gripping the lid.

A further development that is particularly advantageous for protecting a user's hand is that the front edge of the cover is groove-shaped on its underside (in front view) to the left and right of a grip area, but not in a section behind the grip area. This has the advantage that steam escapes next to the user's hand, but not in the area of the hand. For example, the handle area can be designed as a handle shell and the grooves can be present on the left or right side of the handle shell.

It is a configuration that the rearwardly rising step is a convexly curved step. This achieves the advantage that a resistance to pushing the cover further backwards beyond the step or its "evaporation position" is clear but not abrupt. This also contributes to a high level of haptic comfort.

In one embodiment, behind the step there is a slope which rises obliquely to the rear, in particular a linear slope. This has the advantage that the cover is lifted upwards on the guide skids and as a result no longer slides over a large area with heavy weight on the damper pan or its seal, which facilitates the sliding movement and reduces mechanical stress on the seal. A further development is that the cover is raised by 3 mm to 5 mm, in particular by approximately 4 mm.

In a further development, the rear section of the seal is designed as a wiping lip or squeegee, which has the advantage that the underside of the lid slides over it when it is opened, whereby condensate on the underside is drawn off and back like a windshield wiper into the damper pan.

In one configuration, the running tracks are designed as second guide links on their rear sections. In this way, advantageously, the vertical profile can also be defined for the rear edge of the lid when it is opened and closed.

In one configuration, the second guide links slope down at least in sections in the direction from the front to the rear. This makes it easier to detach or remove the cover without complex mechanical unlocking.

In one configuration, at least one of the second guide links is designed as a stop for the guide skids or has such a stop. This prevents, in a way that is easy to implement, that the cover can be pushed back completely into the drawer housing when the drawer is extended and consequently remain accessible.

In a further development, the first and/or second guide links are formed into the tops of the side walls, e.g. by stamping or bending sheet metal. In a further development, the first and/or second guide links are separately manufactured components, e.g. made of plastic, which are inserted into suitable recesses in the side panels.

In one embodiment, the cover additionally has a mounting part or end piece made of plastic that is attached to the rear of the glass pane, with the at least one pin being arranged on the mounting part that is attached to the rear (also simply referred to as the rear mounting part). This facilitates the provision of the pin. In particular, the spigot can be made in one piece with the rear socket part or, for example, injected into it. It is a further development that the rear mount part extends over the same width as the glass pane.

In a further development, the glass plate is connected or glued to at least one mount part by gluing. In a further development, the glass plate is inserted into at least one mounting part and glued to it. In a further development, at least one mount part is injection molded onto the glass plate or the glass plate is injected into the at least one mount part.

It is an embodiment that the spigot piece is attached directly to the glass plate. This results in the advantage that the rear socket part can be dispensed with in a particularly simple manner. In a further development, the spigot piece is glued to an upper side of the glass plate, for example, and/or is a spigot piece that is screwed through the glass plate.

A development that is advantageous for better cleanability is that the cover can be removed or taken out. This can be implemented, for example, in that when the drawer is in the pulled-out state, the cover can be lifted at the front and ejected at the rear from its closed position.

The object is also achieved by a domestic cooking appliance, having a steam cooking appliance as described above and, in addition, another cooking appliance arranged separately therefrom, which has a stationary cooking chamber that can be closed with a (separate) door.

The household cooking appliance can be designed analogously to the steam cooking appliance and has the same advantages. The household cooking appliance can also be referred to as a “multi-cavity” cooking appliance if the steam treatment drawer or the steam cooking appliance and the further cooking appliance are housed in a common housing.

This domestic cooking appliance has the advantage that the further cooking appliance and the steam cooking appliance equipped with the steam treatment drawer can be opened, loaded and operated independently of one another, so that, for example, an ongoing steam treatment process in the steam treatment drawer is not affected by opening the oven door. In addition, the food that has been steam-treated in the steam-treatment drawer can be removed particularly easily. Another advantage is that the steam treatment drawer is particularly easy to clean.

The fact that the steam cooking appliance is arranged separately from the other cooking appliance, in particular within the common housing, includes in particular that it cannot be closed by a common oven door with the oven chamber or is not arranged behind it when the oven door is closed. However, the steam cooking appliance and the other cooking appliance can be operated, for example, via a common operating device and/or the operation of both cooking appliances can be controlled via a common control device, in particular also coordinated with one another, e.g. with regard to the same end of the cooking time.

In a further development, the further cooking appliance is arranged above the steam cooking appliance, which has the advantage of particularly easy access to the steam treatment drawer.

The additional cooking appliance can be, for example, an oven, a microwave oven, or a combination thereof. If the additional cooking appliance is an oven or has an oven functionality, one or more radiant heaters can be assigned to the cooking chamber (which can then also be called an oven chamber) in a further development. and/or a microwave generator. A heat radiator can include at least one resistance heater (eg bottom heat, top heat, grill and/or hot air heater, eg electric resistance tubular heater) and/or at least one infrared heater. If the additional cooking appliance is a microwave appliance or has a microwave functionality, it can be a microwave generator in a further development have, for example a magnetron or a semiconductor-based microwave generator. It is a development that the cooking chamber of the additional cooking device or the additional cooking device is capable of pyrolysis.

The fact that the cooking chamber of the further cooking appliance is stationary means in particular that it cannot be pulled out like a drawer, but is arranged in a stationary manner in the appliance.

Another advantage is that the household cooking appliance can be designed to be particularly compact, in particular so compact that it fits into a built-in niche of 60 cm×60 cm (built-in height×built-in width). It is a further development that the oven has an installation height of approx. 45 cm and the steam treatment drawer or the associated steam treatment cooking device has an installation height of approx. 15 cm.

1 shows a sectional side view of a sketch of a multi-cavity household cooking appliance 1 with an oven 2, the stationary oven chamber 2a of which can be closed by means of a pivotable oven door 3, as indicated by the curved double arrow. Inside a housing 4 of the household cooking appliance 1 below the oven 2 is a separately arranged steam cooking appliance 5 with a steam treatment drawer 6, which can be moved in and out horizontally, for example manually and/or by motor, into a stationary drawer housing 7 of the steam cooking appliance 5, as shown by indicated by the straight double arrow. The steamer 5 has a lower height than the oven 2 and is arranged below the oven 2 .

In the oven door 3 there is a common device control 8 including a control panel for the oven 2 and the steamer 5. Using the device control 8 can be the Oven 2 and the steamer 5 control individually, so that items to be treated, for example items to be cooked such as food, meals, etc., can be prepared independently of one another. The furnace chamber 2a can be heated by means of energy supply devices in the form of a top heating element 9 shown as an example and a bottom heating element 10, in particular by clocking the respective power supply. The heaters 9 and 10 are controlled by the device control 8. The device control 8 is also set up in particular to coordinate the treatment processes taking place in the oven chamber 2a and in the steam treatment drawer 6, in particular the end times of the treatment processes, energy inputs and/or an exhaust air control.

The household cooking appliance 1 is in particular so compact that it fits into a built-in niche of 60 cm x 60 cm (built-in height x built-in width). In particular, the oven 2 can have a height of approximately 45 cm, while the steamer 5 has a height of approximately 15 cm.

Now also referring to 2 the steam cooking appliance 5 has an evaporator receiving area 12 which is arranged behind a front cover plate (“front plate” 11) and in which there is a modular evaporator 13, comprising a steam generation unit and a water tank connected to it (not shown). The steam generation unit and the water tank can be removed individually or together from the evaporator receiving area 11 or alternatively permanently installed therein. The water tank can be filled with water via a lockable tank cap 14 .

When viewed from the front, behind the evaporator receiving area 12 is a damper tray receptacle in the form of a damper tray insertion area 15. The evaporator receiving area 12 and the damper tray insertion area 15 are (in a front view) consecutively arranged areas of a horizontally extendable support frame 16 of the steam treatment drawer 6.

The damper pan insertion area 15 has the shape of a border with lateral cheeks 17, a front wall 18 and a rear wall 19. At least the lateral cheeks 17 are designed as hollow profiles - here with a rectangular cross-section - which makes them particularly light and allow electrical lines (not shown) to be passed through in a protected manner, e.g. electrical lines for the power supply of heating elements for the evaporator 13, possibly .a pump and, if necessary, signal lines. In the hollow cheeks 17 there are also running rails (not shown), e.g. A further advantage of using hollow profiles is that they allow a wide support surface 20 on the upper side to be formed in a simple manner for supporting a cooking product receiving pan in the form of a damping pan 21 . The front wall 18 and the rear wall 19 can also be designed as hollow profiles or as simple walls without a hollow profile and also provide support surface(s) 20 for supporting the damper pan 21 .

The damper trough 21 has a trough-shaped or shell-shaped metallic trough part 22, specifically here with a cuboid basic shape that is open at the top. The trough part 22 has on its upper side a peripherally closed flange or edge region 23 which is bent over laterally outwards and via which it can be placed on the support surface 20 from above. The damper pan 21 can therefore be inserted into the damper pan insertion area 15 from above. The upper opening of the steamer trough 21 forms a loading opening 24 for the use of items to be treated with steam, e.g. items to be cooked. For this purpose, for example, suitable inserts E can be inserted into the damper trough 21, on which the items to be treated can be placed. The use of such inserts E makes it easier to load and remove food, particularly when the damper pan 21 is used, but is not absolutely necessary.

In the area bordered laterally by the lateral cheeks 17 and the walls 18, 19, the damper pan insertion area 15 has no bottom. When the damper trough 21 is inserted, its bottom 25 forms a flush part of the bottom of the steam treatment drawer 6 within the border 17 to 19. As a result, the damper trough 21 can be designed to be particularly deep and consequently large in volume. Furthermore, there is no bottom of the support frame 16, which advantageously results in a saving of material.

The damper trough 21 also has laterally protruding handles 26 for easy handling, which when the damper trough 21 is in the inserted state can be fitted into a respective recess in the lateral cheeks 17 that is open at the top in the form of respective depressions 27 .

The damper pan 21 also has a steam inlet duct 28 made of plastic, which is elongated laterally in a horizontal orientation and is attached to a front wall 29 of the pan part 22 and which, when the damper pan 21 is in the inserted state, forms a steam connection with the steam generation unit of the evaporator 13.

The damper pan 21 can also optionally have a steam outlet duct (not shown), which is attached to a rear wall of the pan part 22 and which, when the damper pan 21 is in the inserted state, has a steam-related connection to a steam removal unit 30, which is present behind the damper pan insertion area 15 in the front view (please refer 1 ) manufactures. The steam removal unit 30 is used at least to divert steam or vapor removed from the steamer tray 21 during a steam treatment process from the steam treatment drawer 5, for example to a vapor extractor or back into the water tank of the evaporator 13. The routing of the steam or vapor into the water tank results in the The advantage is that this is cooled by the water in it and then drier and cooler can be drained from the water tank, eg via a dedicated gas outlet (not shown). This in turn saves energy and water.

Device control 8 is in 2 arranged above the oven door 3 by way of example.

1 also shows a cover 31, which can be placed on the upper side of the edge area 23 of the damper pan 21, preferably via a seal 32 (see FIG 4 ) in the closed state to press on the seal 32 with its weight and thus prevent or at least make it more difficult for steam to escape through gaps or leaks between the damper pan 21 and the cover 31. Here, the seal 32 is a circumferentially closed seal attached to an upper side of the edge region 23 of the pan part 22 of the damper pan 21 .

The damper trough 21 and the cover 31 form or delimit a steam treatment chamber 33 in which the material to be treated can be subjected to steam. The cover 31 can be moved on the support frame 16 in the direction of movement of the steam treatment drawer 6, i.e. here: from the front to the rear to open the cover 31 and from the back to the front to close the cover 31.

3 shows a possible cover 31 of the steam treatment drawer 6 in a view obliquely from above, which has a glass pane 34, a mounting part 35 attached to it at the front and a mounting part 36 attached to it at the rear. The two socket parts 35 and 36 are glued to the glass pane 34, with the glass pane 34 also being inserted into the front socket part 35 here. They extend over the same width as the glass pane 34. The two socket parts 35 and 36 are advantageously made of plastic. The glass pane 34 consists of transparent or opaque glass.

The front mounting part 35 has a grip (area) 37 that is accessible from the top and a guide skid 38 that projects downwards on the left and right. The cover 31 rests with its guide skids 38 on the lateral cheeks 17 of the support frame 16 . When the cover 31 moves, the guide runners 38 run on raceways LB formed in the lateral cheeks 17, as will be explained in more detail below.

The rear socket part 36 has a spigot piece 39 which stands up in the middle on the top side and in the front view, which has a T-shape in the front view and has been produced in one piece with the rear socket part 36 . To be more precise, the spigot piece 39 has a vertically projecting leg section 40, at the upper end of which a crossbar is attached, which in front view has a sliding pin 41l projecting on the left and a sliding pin 41r projecting on the right. In particular, the spigot piece 39 is directly adjacent to a rear edge of the rear socket part 36 and thus of the cover 31.

4 shows a section of a possible variant of the steamer 5 with the cover 31 in its steam-off position in a view obliquely from above. In the evaporation position, the cover 31 is a gap (e.g. approx. 20 mm) from its closed position (see 8th ) open. As a result, it no longer rests on the seal 32 at the front, but still covers the damper pan 21 in such a way that there is no gap visible from above. Rather, on the underside of the front edge of the front mounting part 35, on the left and on the right next to the grip area 37, there is a channel (not shown). The two grooves connect the damper trough 21 to the environment in such a way that steam escapes from the damper trough 21 through the grooves in front of the front edge of the front socket part 35 . The advantage is thus achieved that the escaping steam neither escapes directly upwards in the direction of a user nor gets into the area of a hand of the user holding the gripping area 37 .

The rear socket part 36 is already immersed in the drawer housing 7 .

5 shows a section of the steam cooking appliance 6 without the lid 31 and without the damper pan 21 in a view obliquely from above 26 of the damper pan 21 each have a notch 42 into which the handle 26 can be inserted, in such a way that it is flush with the depression 27 on the upper side.

At the front, a first guide link 43 adjoins the depression 27 at an inner step, which is designed here as a separately manufactured component that is subsequently inserted into the upper side of the lateral cheek 17, e.g. made of plastic. In a front view from the front to the rear, the first guide link 43 has a first area (“stop area”) 44 which is formed flush with the charging surface 20 on the upper side. Behind this is a lowered area 45, which runs at least approximately horizontally in the direction from front to rear, which is followed by a convexly curved step 46 that rises to the rear, which merges into a riser area 47 that rises linearly to the rear, which in turn leads to a horizontal region 48 which is adjacent to the notch 42 and which is flush with the charging surface 20 on the upper side.

At the rear, a second guide link 49 follows the recess 27 on the inner step, the front section 50 of which runs horizontally and the rear section 51 of which is raised in steps and from front to back initially also runs horizontally, only to fall further down. The debris also aids in lifting the lid 31 for cleaning.

In the fully closed position, the in 8th is shown, the guide skid 38 hits the rear edge of the stop area 44 . In addition, the front edge of the front socket part 35 strikes the upper side of the evaporator receiving area 12 . The rear socket part 36 rests on the rear section 51 . In the fully open position (which is shown below in 13 shown), the guide skid 38 hits the rear section 51 .

6 shows a top view of a section of the steam treatment drawer 6 without the cover 31. The track LB of the guide skid 38 runs in the form of a band from the front to the rear between the outer, higher step 17o of the side cheek 17, which also serves as the side outer wall, and the damper trough 21.

7 shows a section of the steam treatment drawer 6 with the cover 31 of the steam-off position in a view obliquely from below. The cover 31 reaches the steam-off position by manually sliding it backwards from its closed state, with the guide skid 38 sliding on the horizontal area 45 until it reaches the step 46, where the user encounters noticeable resistance to further displacement. The position of the guide runner 38 on the step corresponds to the steam-off position, in which steam escapes from the damper trough 21 through the grooves (and in particular only through the grooves) into the environment.

If necessary, a user can now wait for a while until enough steam has escaped and then push the cover 31 with the guide skid 38 over the step 46 and the rise area 47 with increased effort, and the guide skid 38 further over the area 48, slide the handle section inserted into the front notch 42, the depression 27, the handle section inserted into the front notch 42 and finally up to the front section 50 of the second guide link 49, until the guide runner 38 touches the rear Section 51 of the second guide link 49 strikes.

8th shows a sectional side view of a section of the steam cooking appliance 5 with the cover 31 completely closed. The rear section of the socket part 36, which has the spigot piece 39, is immersed in the drawer housing 7, so that the spigot piece 39 is normally not visible to a user.

Furthermore, a guide rail 52 placed in the center and close to the ceiling in the drawer housing 7 in the front view is also shown. The guide rail 52 is tubular, is aligned with respect to its longitudinal extension in the direction of movement of the drawer 6, namely in the direction from the back to the front, and has a funnel-shaped front section 53. The spigot piece 39 is located at a distance in front of the funnel-shaped section 53.

When the cover 31 is completely closed, its guide skids 38 rest on the horizontal areas 45 of the respective guide links 43 . As a result, the cover 31 rests with its full weight on the seal 32 of the damper pan 21 .

9 shows a section of the steam cooking appliance 5 with the lid 31 in a first intermediate position which is further open beyond the steam-off position, in a view obliquely from above. 10 shows the steamer 5 with the lid 31 in the first intermediate position as a sectional side view. In the first intermediate position, the cover 31 has been pushed so far that the guide runners 38 have now been pushed up the stage 46 and the rise area 47 and on the Area 48 have come to rest. Since the area 48 is higher than the area 45, the cover 31 is raised upwards at the front (eg by 3 mm to 5 mm, in particular by 4 mm) and no longer rests on the entire seal 32 with its full weight. Instead, its weight now rests more heavily on the rear edge section of the seal 32, which can be designed in particular as a wiper lip or strip. The slight inclination of the cover 31 is supported by the shape of the rear section 51 of the second guide link 49 sloping backwards.

11 shows in a too 4 In the second intermediate position, the guide runners 38 are located on the respective tracks LB between the two guide links 43 and 49. During the transition Due to its slight inclination, the cover 31 can be moved from the first intermediate position to the second intermediate position comparatively easily and without high friction over the entire surface with the seal 32 . The rear section of the seal 32, on which the cover 31 still rests with a comparatively high weight, serves as a wiping element similar to a windshield wiper, which wipes off the condensate on the underside of the cover and allows it to flow back into the damper pan 21.

In the second intermediate position, the pin piece 39 is immersed in the open, funnel-shaped front section 53 of the guide rail 52, as shown in more detail in FIG 12 shown. The guide rail 52 has a tubular or profile-like shape which is aligned in the direction of insertion of the steam treatment drawer 6 and thus in the direction of travel of the cover 31 and which is advantageously closed at its rear end face. It has a slot 54 on the underside, which separates a left-hand running surface 55l from a right-hand running surface 55r. More specifically, the vertically projecting leg portion 40 plunges into the slot 53 so that the left-side protruding slide pin 411 can slide on the left-side raceway 551 and the right-side protruding slide pin 41r can slide on the right-side raceway 55r.

As the cover 31 is opened further, the pin piece 39 is pushed further into the guide rail 52 and guided by it. This achieves the advantage, among other things, that the cover does not wobble and, moreover, cannot fall or tilt into the drawer housing 7 .

13 shows in a too 8th analogous view of the steamer 5 with the lid 31 in its fully open position. The cover 31 is now pushed completely or almost completely into the drawer housing 7, with the handle area 37 still being able to be gripped by a user. The guide skid 38 strikes the rear section 51 of the second guide link 49 . In the fully open position, the damper pan 21 can be lifted out of the damper pan receiving area 15 by its handles 26 .

14 shows in a too 8th analogous view of the steamer 5 with the steam treatment drawer 6 retracted. The cover 31 is completely closed. The lid 31 can be closed manually by a user before the steam treatment drawer 6 is moved into the drawer housing 7 . Alternatively, the user can retract the steam treatment drawer 6 manually or by motor when the lid 31 is partially or completely open, as a result of which the lid 31 is automatically closed. In particular, the fact that the cover 31 can have a stop in the rear area in its fully open position can be used here.

15 shows in a too 3 analogous view another possible cover 31A, which can be used as an alternative to the cover 31 with the steam treatment drawer 6. The cover 31A has a glass pane 34A, to which a front socket part 35 as in the case of the cover 31 is connected at the front. However, in contrast to the cover 31, the rear mounting part 36 is dispensed with, but a knob-like upstanding pin piece 39A is attached centrally and directly adjacent to the rear edge in a rear section of the glass pane 34A, eg screwed and/or glued thereto. The spigot piece 39A also has a T-shape in its protruding section in a front view, but is, for example, rotationally symmetrical or circular in a plan view. The sliding pin 41AI projecting to the left of an upstanding leg section 40A is then formed by the disk area of the journal piece 39A projecting to the left, and the sliding pin 41Ar projecting to the right is formed analogously by the disk area of the journal piece 39A projecting to the right.

16 shows in a too 5 analogous representation, a steam treatment drawer 6B in a further possible embodiment, which can be used as an alternative but functionally equivalent to the steam treatment drawer 6. The drawer housing 7 is not shown. The steam treatment drawer 6B has the same basic structure as the steam treatment drawer 6, but now the guide links 43 and 49 of the steam treatment drawer 6 and the lateral support surface for the damper pan 21 is designed as a single plastic part 56.

17 shows in a too 11 analogous view of a steamer 5C with the lid 31C in the open first intermediate position. The steam cooking appliance 5C has a structure similar to that of the steam cooking appliance, but the pin piece 39 and guide rail 52 are now dispensed with. Instead, on the rear mounting part 36C (in front view) there is a sliding pin 571 projecting on the left and a sliding pin 57r projecting on the right, which are advantageously not yet in the closed position of the cover 31C, but at least from the first intermediate position on in the area of a left side wall of the drawer housing 7C located guide rail 58l or on a located in the region of a right side wall of the drawer housing 7C guide rail 58r movably rest. The guide rails 581 and 58r are designed here as profile-shaped guide angles. They can be designed at the rear as a stop against the sliding pins 571 or 57r.

Of course, the present invention is not limited to the embodiment shown.

Thus, elements of the steamer described above can be used alternatively or in combination between different embodiments, e.g. the lid 31A with the steamer drawer 6B, etc.

Furthermore, the pins can be designed as roller pins instead of sliding pins.

In general, "a", "an" etc. can be understood as a singular or a plural number, in particular in the sense of "at least one" or "one or more" etc., as long as this is not explicitly excluded, e.g. by the expression "exactly a" etc.

A numerical specification can also include exactly the specified number as well as a usual tolerance range, as long as this is not explicitly excluded.
