Description

food drawer

The invention relates to a cooking product drawer, having a housing from a drawer housing horizontally extendable support frame, held by the support frame Gar gut receiving pan, which has a top loading opening, and a cover for covering the loading opening De. The invention also relates to a method for handling such a cooking product drawer. The invention can be used particularly advantageously on food drawers in the form of steam treatment drawers of household steam cooking appliances.

Oven/steaming drawer combinations are known in which a steaming drawer is located below an oven. A loading opening on the upper side of the damper tray that is permanently installed in the drawer can be covered by means of a pivoting 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. Another disadvantage is that when the lid is opened after a steam treatment process, it is difficult to release the steam that is still present in a controlled manner

It is the object of the present invention to at least partially overcome the disadvantages of the prior art.

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

The object is achieved by a cooking product drawer, having a support frame that can be extended horizontally from a drawer housing, a cooking product receiving tray that can be placed in the support frame and has a loading opening on the top side, and a lid for covering the loading opening, the lid being horizontal in this way in the travel direction of the supporting frame on the Support frame is displaceable in that it can be displaced from a closed position into an open position when the support frame is extended, in which it is pushed into the drawer housing, and that it can be moved into its closed position when the support frame is extended and in the open position by retracting the support frame into the drawer housing.

Compared to an embodiment with a hinged lid, the advantage is achieved that the movable lid does not obstruct any parts arranged above it, even when open, e.g. cannot collide with an open oven door. Furthermore, when the lid is opened after a steam treatment process, the steam that is still present can be released in a simple and controlled manner through the then forming, localized gap between the cooking goods receptacle and the lid. There is also a higher quality impression than with a hinged lid.

The fact that the food receiving pan can be inserted into the support frame includes, in particular, that the food receiving pan can be inserted into the support frame on the user side and can also be removed again, in particular from or upwards. The side of the cooking tray that is open at the top represents its loading opening.

The cover can be placed on the loading opening or its border, in particular tightly. The food receiving pan and the lid then form or delimit a food treatment space, e.g. a steam or vacuum treatment space. The cover is held on the support frame in particular by its own weight. This also causes the effective sealing of the food receiving tray.

The support frame can (in front view) be pulled out of its drawer housing and retracted, e.g. manually or mechanically (e.g. by means of a spring mechanism) and/or motorized. When the support frame is extended, the cover can be moved backwards or forwards on the support frame.

In one embodiment, the cooking product drawer is a steam treatment drawer and the cooking product receiving pan is a steamer pan. Alternatively, the food drawer can be a warming drawer or a vacuum processing drawer.

In one embodiment, the cover is a separate component and, when the supporting frame is extended, can be lifted off the supporting frame at least from its closed position. So the advantage is achieved that the lid of a user separately Can be removed for cleaning, which makes cleaning easier. In particular, the cover can be a dishwasher-safe cover, so that it can be cleaned particularly easily and thoroughly in a dishwasher.

In one configuration, the cover has at least one glass pane, which covers the charging opening when the cover is closed. This has the advantage that the lid is particularly durable and hard-wearing, because glass is very resistant to mechanical and chemical influences (e.g. from superheated steam). It is a further development that the glass pane is transparent, since a user can then view the food to be cooked in the food receiving pan even when the lid is closed.

One configuration is that the lid, when closed, protrudes laterally over the charging opening on all sides, rests with a seal on the underside on an edge of the cooking product receiving pan (e.g. designed as a flange) and on its left- and right-hand sections that protrude over the seal (in front view). each has a sliding surface for displaceable support on the support frame. In this way, the advantage is achieved that when the lid is closed, the loading opening can be covered particularly reliably. In addition, the cover outside of the seal can be designed in a particularly diverse manner in terms of construction. For example, a shape and a material of the sliding surfaces can be designed without the need for steam or vacuum resistance.

In general, the lid in the closed state (in front view) can protrude only on the left and right side over the loading opening or on the front, left and right side over the loading opening.

In one embodiment, the sliding surfaces and/or the region of the edge of the cooking product receiving pan that contacts the sliding surfaces are covered with or consist of a material that is extremely easy to slide. A particularly easy displaceability is thereby provided.

It is a further development that the highly slippery material is or has polyoxymethylene (abbreviation POM). POM is advantageously characterized by high strength, hardness and rigidity over a wide temperature range. It retains its high toughness, has high abrasion resistance, a low coefficient of friction, high heat resistance, good sliding properties, good electrical and dielectric properties and low water absorption.

The sliding surfaces can be designed as strip-shaped, flat sliding surfaces. Alternatively, the sliding surfaces can be formed on downwardly projecting projections ("sliding cams").

In one embodiment, the lid has a central glass pane on which the seal is attached underneath and which is surrounded on all sides by a lid frame made of plastic, with the sliding surfaces being provided on the underside of lateral sections from the lid frame. This achieves the advantage that the areas of the cover on the side of the seal can be easily and inexpensively formed, e.g. as an injection molded component, even with more complex shapes.

In general, when the cover is closed (front view), it can only be on the left and right side of the seal or on the front, left and right side of the seal. Such a cover frame can also generally be dispensed with, in which case the sliding surfaces can then be attached to the underside of the glass pane as such, e.g. glued to it.

In one embodiment, the support frame has a wiper lip which, when the cover is closed, is arranged behind the seal and makes contact with the underside of the cover. Thus, when the cover is moved backwards, controlled dripping or removal of condensate from the underside of the cover is made possible, in particular into the cooking item receiving pan.

In one embodiment, there are slide rails on the left and right side of the drawer housing, on which a section of the lid that is located within the drawer housing can be held in a displaceable manner. This advantageously prevents unwanted tilting of the open lid. The slide rails can also be covered with highly lubricious material. When the support frame is extended and the lid is open, the lid, in particular with its sliding surfaces, can either already be (a short length) rest on the slide rails or be pushed onto the slide rails by pushing in.

In one embodiment, the cooking product drawer has at least one stop against displacement of the cover into the drawer housing beyond a completely pushed-in state. This prevents damage to the lid or the drawer housing. This also ensures that the lid fits snugly on the cooking tray.

The stop can be provided, for example, by a stop on a rear area (when viewed from the front) of the slide rails. Alternatively or additionally, if the sliding surfaces of the cover are formed by sliding cams, a stop can be present in the path of the sliding cams.

A stop towards the front is provided in particular by a region of the support frame which stands in the way towards the front in the displacement direction of the cover.

It is a further development that a guide of the lid against a movement to the left or right (in front view) ("left-right guide") left and right cheeks of the support frame are designed as profile-like steps ("stepped profile") on the top and the Cover to have a complementary or matching profile-like stage. The profiles extend in the direction of displacement of the cover. It is a further development that a seal of the cover is arranged on an inner, lower step of the stepped profile and a bearing surface resting on the support frame is formed by an outer, higher step of the stepped profile. Conversely, the inner, deeper step of the stepped profile of the support frame corresponds to the bearing surface for the cooking goods receiving pan (on which the seal rests) and the outer, higher step to the bearing surface for the lid.

In an alternative or further development, the left-right guide can also be formed via an edge of the support frame that protrudes to the side of the cover. The edge can be designed as a profile over the entire travel length or also partially. In one embodiment, the cooking product drawer has a locking device for holding the lid in its closed position. This advantageously avoids an unintentional slight opening of the cover. The locking device can hold the lid in its closed position with a positive or non-positive fit.

In one embodiment, the locking device is a magnetically acting locking device, that is to say it holds the cover in its closed position in a non-positive manner by means of magnetic force. This refinement can be implemented in a particularly simple and robust manner. For example, the cover can have at least one permanent magnet on its front edge, while the support frame has at least one permanent magnet of reversed polarity in the area of the associated abutting edge. A user can then simply push the lid open from its closed position.

In one configuration, the magnetically acting locking device has at least one electromagnet arranged on the support frame and at least one permanent magnet arranged on the cover and a polarity reversal device that can be triggered by the user, the at least one electromagnet being energized when the support frame is extended without actuating the polarity reversal device in such a way that that it magnetically attracts the min least one permanent magnet and is energized in the opposite current direction when the reversing device is actuated. This achieves the advantage that when the polarity reversing device is triggered or actuated, the lid is repelled, which opens the lid a gap and thereby allows steam or hot air to be released from the cooking goods receiving tray in a particularly user-friendly manner and in a way that is particularly safe for the user allows.

In a further development, the locking device has at least one bolt for positively locking the cover in its closed position. This can automatically lock the lid, in particular when it is brought into its closed position. Unlocking can be performed by an unlocking device that can be actuated by the user, for example by a manually or motor-driven unlocking device. The unlocking device can be arranged on the cover, on the support frame or on the cover and on the support frame. In one configuration, the cover has a handle shell. This facilitates handling of the lid in a way that is particularly convenient and safe for a user, since the handle shell acts as a protective wall against escaping steam or hot air. If present, the unlocking device or at least the part thereof that can be actuated by a user (eg a button, a button, a lever, etc.) can be accommodated in the grip shell.

In a further development, the grip shell has a sealing surface on its underside if it rests on the edge of the pan for the food to be cooked when the lid is closed.

The grip shell can be arranged in the glass pane, in a cover frame surrounding the glass pane, or partly in the glass pane and partly in the cover frame. In the latter case, a part of the grip shell can be inserted, for example, in a U-shaped cutout on the edge of the glass pane.

The object is also achieved by a household cooking appliance with a food drawer as described above. The household steam cooking appliance can be designed analogously to the food drawer and has the same advantages.

The household cooking appliance can only have at least one cooking food drawer (“stand-alone appliance”) as the functional unit for handling the food

In a further development, the household cooking appliance has at least one additional cooking product handling functional unit of a different type with its own cooking chamber separate from the cooking product drawer, e.g. an oven, in addition to the at least one cooking product drawer. The oven can be, for example, an oven, a microwave oven or a combination thereof. This can also be referred to as a "multi-cavity" cooking appliance.

It is a further development that the food drawer is arranged below the other functional unit for treating food, in particular the oven, since particularly good accessibility and easy handling of the food drawer is advantageously achieved in this way. Furthermore, the household cooking appliance can be a household steam treatment appliance, the food drawer of which is a steam treatment drawer, with the food receiving pan being a damper pan. Such a steam treatment drawer can have an evaporator for generating steam that can be introduced into the steamer pan, in particular also a water tank for supplying water to a steam generating device of the evaporator.

It is a further development that the steam generation unit and the water tank are components of the evaporator—particularly ones that can be separated from one another. Specifically, the steam generation unit can then have a heatable shell ("evaporator shell") that can be removed by the user and has an open top and a plate or cover ("adapter plate") that can be placed on the open top of the evaporator shell by the user, the adapter plate has a steam outlet opening for steam to escape and have a depression ("receiving depression") with a water passage opening for the user to insert the water tank, and the water tank has a water outlet for letting water out into the evaporator shell. In a further development, the water outlet has a locking mechanism which blocks the water outlet when the water tank is removed and releases it when the water tank is inserted. It is a further development that the evaporator has a shut-off valve which is set up to open or close as required depending on the water level in the evaporator shell. In a further development, the evaporator shell has an internal volume with a rectangular basic shape. In a further development, the edge area of the adapter plate can be placed on an upper edge of the evaporator shell and the vapor outlet opening of the adapter plate is arranged next to its receiving recess. It is a further development that the internal volume of the evaporator shell corresponds to at least one filling volume of the water tank. In a further development, the evaporator has a filter holder, which can be arranged in a vapor space delimited by the evaporator shell and the adapter plate above a nominal filling level of the evaporator shell. In a further development, steam generated by the steam generating unit can be routed through the steam outlet opening into the damper pan.

In particular, the steam can exit in a targeted manner from a steam outlet opening of the steamer pan and be guided to a vapor extraction of the oven. Alternatively - also oh- ne Presence of another functional unit that treats the food - the excess wet steam returned from the steamer pan is guided past the outer walls of the (typically cold) water tank in order to condense there and run back into the evaporator shell.

The object is also achieved by a method for handling a food drawer, which food drawer has a support frame that can be extended horizontally from a drawer housing, a food receiving tray that can be inserted into the support frame and has a loading opening on the top, and a cover that can be displaced horizontally on the support frame in the direction of travel of the support frame for covering the loading opening, in which case the cover, with the support frame extended, is moved from a closed position into an open position, in which it is pushed into the drawer housing, and wherein the cover, when the support frame is extended and in the open position, is pushed in by retracting the support frame in the drawer housing is moved to its closed position. The method can be designed analogously to the food drawer and the household steam cooking appliance and has the same advantages.

The properties, features and advantages of this invention described above, and the manner in which they are achieved, will become clearer and more clearly understood in connection with the following schematic description of an exemplary embodiment, which will be explained in more detail in connection with the drawings.

1 shows a sectional side view of a sketch of a multi-cavity household cooking appliance 1 with a stationary oven cavity 2 of an oven whose frontseiti GE loading opening can be closed by means of a pivoting oven door 3, as indicated by the curved double arrow. Inside a housing 4 of the household cooking appliance 1 below the oven chamber 2 or oven, there is a cooking product drawer, which is arranged separately from the oven chamber 2 and is in the form of a steam treatment drawer 5, which is manually and/or mechanically supported horizontally in a stationary drawer housing 60 - And can be extended, as indicated by the straight double arrow, e.g. via a telescopic extension or rails. The steam treatment drawer 5 has a lower height than the oven compartment 2 and is arranged below the oven compartment 2 .

In the oven door 3 there is a common appliance control 6 including a control panel for the oven compartment 2 or for an oven having the oven compartment 2 and the steam treatment drawer 5. The appliance control 6 can be used to control the oven compartment 2 and the steam treatment drawer 5 individually, so that therein be-sensitive items to be treated, eg items to be cooked such as food, dishes, etc. can be prepared independently of one another. The furnace space 2 is by means of energy input devices in the form of a top heat radiator 7 shown as an example and a bottom heat Radiator 8 heated, in particular by clocking the respective power supply. The heaters 7 and 8 are controlled by the device control 6. The device control 6 is also set up in particular to coordinate the treatment processes taking place in the furnace chamber 2 and in the steam treatment drawer 5, in particular the end times of the treatment processes, energy inputs and/or an exhaust air control vote.

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).

Referring now also to FIG. 2, the steam treatment drawer 5 has an evaporator receiving area 11 arranged behind the cover plate 10, in which a modularly constructed evaporator 12 to 13 comprising a steam generating unit 12 and a water tank 13 connected thereto are present. The steam generation unit 12 and the water tank 13 can be removed individually or together from the evaporator receiving area 11 or alternatively permanently installed therein. The water tank 13 can be covered on the top by a removable tank cap 14 .

In a front view behind the evaporator receiving area 11 there is a damper pan insertion area 15. The evaporator receiving area 11 and the damper pan inserting area 15 are areas of a horizontally extendable support frame 30 arranged one behind the other.

The damper pan insertion area 15 has the shape of a border with lateral cheeks 16, a front wall 17 and a rear wall 18. At least the cheeks 16 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 steam generation unit 12, possibly a pump and, if necessary, signal lines. In the hollow cheeks 16 are also running rails (o. Fig.), For example, a Tele skopauszugssystems, the steam treatment drawer 5 accommodated. A further advantage of using hollow profiles is that they allow the formation of a wide, top-side support surface 19 for supporting a cooking product receiving pan in the form of a damper pan 20 in a simple manner. At least the cheeks 16 and the rear wall 18 have flat surfaces here, which supports their ease of cleaning un. The front wall 17 and the rear wall 18 can also be designed as hollow profiles or as simple walls without a hollow profile. Your tops can also serve as a bearing surface 19, but do not need it.

The damper pan 20 is trough-shaped or shell-shaped, in this case with a cuboid basic shape that is open at the top. On its upper side, the damper pan 20 has a flange or edge region 21 which is bent laterally outwards and is closed all the way round, via which it can be placed onto the bearing surface 19 from above. The damper pan 20 can be replaced from above into the damper pan insertion area 15 bar. The upper opening of the steamer trough 20 forms a loading opening 20a for the use of items to be steamed, e.g. For this purpose, suitable inserts E can be used in the damper pan 20, on which the treatment material can be placed. The use of such inserts E makes it easier to load and remove food, especially when the steamer pan 20 is used.

In the area bordered laterally by the cheeks 16 and the walls 17, 18, the damper pan insertion area 15 has no bottom. When the damper pan 20 is used, its bottom 22 forms a flush portion of the bottom of the steam treatment drawer 5 within the border 16 to 18. As a result, the damper pan 20 can be designed to be particularly deep and consequently large in volume. Furthermore, there is no bottom of the supporting frame 30, which advantageously results in a saving of material.

The damper trough 20 also has laterally protruding handles 23 for easy handling, which when the damper trough 20 is in the inserted state can be fitted into a respective recess of the lateral cheeks 16 which is open at the top in the form of respective depressions 24 .

The damper pan 20 also has a steam inlet duct 25 made of plastic that is stretched longitudinally in a horizontal direction and is attached to the front wall 17 the steam generating unit 12 forms. The damper pan 20 also has a steam outlet channel 26 (see Figure 4), which connects to the rear wall 18 and the im When the damper pan 20 is in the inserted state, it establishes a steam-related connection to a steam removal unit 27 (see FIG. 4) that is present behind the damper pan insertion area 15 in a front view. The steam removal unit 27 serves at least to discharge steam from the steam treatment drawer 5 during a steam treatment process from the steamer pan 20, for example to a fume hood.

1 also shows a cover 28, which can be placed on top of the edge area 21, preferably via a seal (not shown), in order to prevent or at least to prevent steam from escaping through gaps between the damper pan 20 and the cover 28 heavy. The damper pan 20 and the cover 28 form or delimit a steam treatment chamber 29 in which the material to be treated with steam can be whipped up there. The cover 26, which advantageously has a transparent glass pane, can be an independent component, can be slidably arranged on the supporting frame 30 or can be connected to the supporting frame 30 so that it can pivot, e.g. via rotary hinges.

3 shows the damper pan 20 in an oblique view from above. The adapter-like steam inlet channel 25 is arranged on the front side 31 facing the front wall 17 below the edge area 21 . It is open on the underside and forms a coupling opening 25b there. It also has a rear steam inlet opening 25a, opening into the damper pan 20 or the steam treatment chamber 29, here: slot-shaped, through which steam D is introduced into the damper pan 20 during a steam treatment process.

The steam outlet channel 26 in the form of an adapter (see FIG. 4) is arranged on the rear side 32 below the edge area 21 . Also has a horizontally stretched basic shape and is open on the underside in the form of a coupling opening 26b (see FIG. 4). The steam outlet duct 26 can be shaped at least largely identically to the steam inlet duct 25 . It also has a front-side steam outlet opening 26a (not shown) that opens into the steamer pan 20 or the steam treatment chamber 29, in this case a slit, through which steam D is discharged from the steamer pan 20 during a steam treatment process and fed to the steam removal unit 27 . 4 shows the steam treatment drawer 5 with the damper pan 20 removed as a sectional view through the evaporator 12 to 13 in a side view. The cover 28 is pushed backwards here and therefore releases the area 15 for inserting the damper pan.

When the damper pan 20 is inserted into the damper pan insertion area 15 from above, as indicated by the wide arrow, an edge of the downward-pointing coupling opening 25b of the steam inlet channel 25 is pushed onto or into a correspondingly shaped, upward-pointing, slit-shaped steam outlet opening 12a of the Steam generating unit 12 placed or, as shown, inserted at the edge, possibly via a seal. As a result, when the damper pan 20 is inserted, a steam channel is created from the steam outlet opening 12a through the steam inlet channel 25 into the damper pan 20, through which steam D generated by the steam generating unit 12 is conducted into the damper pan 20, as indicated by the arrows on the left. The vapor outlet opening 12a and the coupling opening 25b thus form a vapor-permeable vapor coupling in the plugged-in state.

When inserting the damper pan 20, the downwardly open coupling opening 26b of the steam outlet channel 26a is also placed on or in a correspondingly shaped open upper side of a receptacle 27a of the steam removal unit 27 or, as shown, inserted at the edge, possibly via a seal. The open top of the receptacle 27a is designed as a steam inlet opening 27b shaped to match the coupling opening 26b. As a result, when the damper pan 20 is inserted, a steam channel is created from the damper pan 20 through the steam outlet channel 26 into the steam removal unit 27, through which steam D that has flowed through the damper pan 20 and possibly contains vapor is conducted into the steam removal unit 27, as indicated by the arrows on the right. The coupling opening 26b and the vapor inlet opening 27b thus form a vapor-permeable vapor coupling when the damper pan 20 is inserted.

Of course, the present invention is not limited to the game shown Ausführungsbei. 5 shows an exploded view of the evaporator 12 to 13 with the steam generation unit 12 and the water tank 13 that can be inserted on the top side in an oblique view from above.

The water tank 13 can be made of transparent plastic and is therefore shown here as semi-transparent. The tank cap 14 can be placed on the water tank 13 which is open at the top. The water tank 13 has a water outlet 40 that protrudes inwards from the bottom, in the form of a tube or a socket, for example, for letting water into the steam generation unit 12 . The water outlet 40 has a locking mechanism (not illustrated) which blocks the water outlet 40 when the water tank 13 is removed and releases it when the water tank 13 is inserted.

The steam generation unit 12 is here, for example, in the form of a heatable evaporator shell 41 with a rectangular basic shape that is open at the top and an adapter plate 42 that can be placed on the open top of the evaporator shell 41 by the user. The adapter plate 42 thus serves as a cover for the evaporator shell 41 . The internal volume of the evaporator shell 41 corresponds at least to the filling volume of the water tank 13.

The adapter plate 42 has a receiving recess 45 with a water passage opening (not shown) for the user to insert the water tank 13 in a form-fitting manner and the (front view) behind the receiving recess 45, for example a slotted steam outlet opening 12a. In the bottom of the receiving recess 45 there can be a connecting piece 46 or pipe (see Fig. 5) that projects upwards and can be inserted into the water outlet 40, which when the water tank 13 is used slides into the receiving recess 45 in the water outlet 40 and the closure mechanism located therein mechanism (e.g. a spring-loaded non-return valve) opens. When the locking mechanism is open, water can flow out of the water tank through the water outlet 40 and the socket 46 inserted therein into the evaporator shell 41 if a shut-off valve (not shown) of the evaporator 12, 13 is open at the same time and is designed to Depending on a water level in the evaporator shell 41 to either open or close, for example a valve ("SchwimmerventN"), which is actuated by a floating in the evaporator shell 41 water float. This makes it possible to also fill only a small amount of water into the evaporator bowl 41 in a controlled manner, which is distributed over the large heatable base area of the evaporator bowl 41 at a comparatively low fill level, so that particularly short reaction times and/or large amounts of steam can be achieved when steam is generated .

In one variant, the water tank 13 can be removed from the receiving recess 45 by means of at least one handle arranged thereon (not illustrated) and/or by means of an automatic lifting mechanism (not illustrated).

At least one heating element is also assigned to the evaporator dish 41 (not shown). The evaporator shell 41 advantageously consists at least partially of metal or ceramic, while the adapter plate 42 advantageously consists of plastic.

The vapor generation unit 12 can have a filter holder (not shown) in its vapor space, which can be arranged above a nominal fill level of the evaporator shell 41 . The portafilter can thus be wetted by the steam in the steam generation unit 12 without being immersed in the water in the evaporator bowl 41 . As a result, the steam emerging from the steam outlet opening 12a can be aromatized if corresponding aroma substances such as containers with spices or herbs or the like are present in the portafilter.

6 shows a section of the steam treatment drawer 5 with the steam generation unit 12 of the evaporator 12 to 13 removed, viewed from an angle from above. The water tank 13 is not shown and may have already been removed, for example.

As indicated by the broad arrow, the evaporator 12 or the evaporator shell 41 can be removed by the user when the damper pan 20 has been removed, for example to the rear from a corresponding evaporator recess 47 in the support frame 30 . The user can then empty the evaporator shell 41 after removing the adapter plate and, if necessary, clean it, in particular decalcify it, together with the adapter plate 42 and/or the water tank 13, for example in a dishwasher. At the bottom of the evaporator recess 47 there is a contact thermocouple (not shown) which, when the evaporator dish 41 is inserted, makes contact with its bottom and thereby measures the outside temperature of this bottom. The sensor readings can be fed to a control device for controlling the evaporator 12, for example for steam regulation (activation and deactivation of the at least one heating element) and for detecting a lack of water (eg emptying). The control device can be a component of the steam treatment drawer 5 or of the household cooking appliance 1 in general. The control device can in particular correspond to device control 6 .

7 shows a section of a cover 28 of the steam treatment drawer 5 in an oblique view from above.

The cover 28 has a peripheral frame ("lid frame" 48) made of plastic with a front frame portion 48a, two side frame portions 48b and a rear or rear frame portion 48c, the pane 49 surrounds a transparent glass. In the front view, a handle shell 50 that is open at the top and thus accessible to the user is inserted in the middle, partly in the front frame section 48a and partly in a front U-shaped cut-out of the glass pane 49 .

Channels 51 are arranged in the front-side section 48a of the frame 48 to the side of the grip shell 50 . The flutes 51 are introduced at a front edge 52 of the front section 48a into an underside of the front section 48a and extend laterally from the handle shell 50 in a front view.

The lateral sections 48b of the cover frame 48 rest on the supporting frame 30 of the steam treatment drawer 5 with sliding surfaces 53 made of a highly lubricious material such as POM, as explained in more detail below with reference to FIG.

Two permanent magnets 54 are also introduced at the front edge 52 .

8 shows a sectional side view sketch of a possible embodiment of the steam treatment drawer 5, the lid 28 being in its fully closed ("closed") state. The glass pane 49 lies through its rests on an upper flange of the damper pan 20 via a gasket 55 (see Fig. 11). The glass pane 49 can be a single pane of glass or, as drawn purely by way of example, be a double pane.

In the closed position, a steam treatment process can be carried out in which steam generated by the steam generating device 12 or its evaporator shell 41 is introduced into the steamer trough 20 and treatment material such as food to be cooked etc. is wetted therein with steam, in particular with superheated steam.

In the closed position, the groove 51 is located in front of the loading opening 20a, so that no steam enters the groove 51.

At least in the closed position, the cover 28, which represents a component of the steam treatment drawer 5 that can be handled separately, can be removed and e.g. cleaned separately, e.g. in a dishwasher.

In the front wall 17 of the damper tray insertion area 15, which also serves as a front stop for the cover 28, there are two electromagnets 56 which are opposite the permanent magnets 54 and which can be reversed by a user-actuated polarity reversal device (not shown). Without actuation, the electromagnets 56 are energized in such a way that they have an electrically attractive effect on the electromagnets 56 and keep the cover 28 closed in a non-positive manner on the front wall 17 . The Umpolungsvorrich device, the electromagnets 56 and the permanent magnets 54 thereby form a magnetically acting locking device for holding the lid 28 in its closed position. When the polarity reversing device is actuated, the current direction is reversed by the electromagnets 56, so that they then have a repelling effect on the permanent magnets 54 and push the cover backwards by a certain distance ("safety distance" s), e.g. 20 mm.

9 shows a sectional side view of a sketch of the steam treatment drawer 5, the cover 28 having now been pushed open by its safety distance s by actuating the polarity reversing device. The cover 28 continues to cover the loading opening 20a in plan view, but the front frame section 48a now covers the loading opening 20a or above the loading opening 20a lies. As a result, the grooves 51 are also above the loading opening 20a and are exposed to it. The handle shell 50 extends up to the front edge of the charging opening 20a, so that little or no vapor D can escape between the handle shell 50 and the damper pan 20.

Rather, the steam D now exits through the grooves 51 acting as steam passage openings, namely horizontally at the front edge 52 of the front frame section 48a next to the handle shell 50, as also shown in plan view by FIG. A user's hand gripping the grip 50 is protected from escaping steam D since the steam D is discharged next to the grip 50, the grip 50 serves as a protective wall and the steam D is discharged horizontally.

A user can now wait for a period of time that is comfortable for him until the amount of steam flowing out has reduced sufficiently, and then push the cover 28 further to the rear. The cover 28 can be pushed so far back into the drawer housing 60 that the damper pan 20 is exposed and can be removed upwards. To do this, the cover 28 is pushed with its sliding surfaces 53 onto slide rails 57 fitted on the left and right in the drawer housing 60, which hold the cover 28 in the drawer housing 60 and, for example, also prevent the cover 28 from tilting. The slide rails 57 can also provide a stop (not shown) to limit rearward displacement of the cover 28 .

To close the cover 28, a user can push it forward again manually. A further possibility is that the user can return the cover 28 to its closed position by moving, e.g. pushing, the support frame 30 into the drawer housing 60 with the cover 28 open.

11 shows a sketch of the steam treatment drawer 5 as a sectional illustration in a front view, the cover 28 here having only one glass pane 49 as an example. The cover 28 projects, as already described in more detail in FIG. In this case, the glass pane 49 on the underside of its edge regions, a peripheral log device 55, via which the lid 28 is vapor-tight due to its weight on the flange of the Damper pan 20 rests, the flange rests on the underside on the bearing surface 19 of the cheeks 16 of the support frame 30 since union.

The bearing surface 19 represents an inner, lower step of a stepped profile formed on the upper side of the cheeks 16 in the front view shown. The outer, higher step of the stepped profile serves as bearing surfaces for supporting a respective sliding surface 53 of the cover 28. The cover 28 has a matching step shape, with an underside of its inner, lower level, the seal 55 and an underside of its outer, higher level, the sliding surface 53 has. Alternatively or additionally, the support surface 19 can consist of a highly slippery material such as POM, at least on its higher step provided for supporting the lateral frame sections of the cover frame 48b.

When the cover 28 is closed behind the seal 55, a wiping lip 59 (see FIGS. 8 and 9) is present on the rear wall 18 of the support frame 30 and contacts the cover 28 on the underside. When the cover 28 is pushed into the drawer housing, the underside of the cover 28 is scraped by the wiper lip 59 and any condensate there is scraped off.

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

In general, "a", "an" etc. can be understood as singular or plural, 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 one" etc.

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