    Description: The invention relates to a filter insert for a filter container of a cooking appliance with a first filter. The invention also relates to a filter container of a cooking appliance, which is set up for receiving a filter insert and has a cup-like basic shape with an upper-side inflow opening, a bottom and a peripheral side wall attached to the floor. The invention further relates to a cooking appliance, comprising a filter container arranged at a bottom of a cooking chamber, which can be connected to a drain of the cooking appliance and to a cleaning device of the cooking appliance. The invention is particularly advantageously applicable to steam ovens.
    DE 10 2004 001 220 B3 discloses a cleaning arrangement for a cooking appliance comprising a cooking chamber, with a cooking chamber inlet and a cooking chamber drain for at least one fluid, in particular comprising water, wash liquor, detergent, rinse aid and / or decalcifier, with a downstream of the cooking chamber arranged shut-off device having a first actuating position, in which a fluidic connection of the cooking chamber drain is produced to a Gargeräteabfluss, and a second actuating position, in which a fluidic connection of the Garraumablaufs to the cooking chamber inlet to form a substantially closed fluid circuit can be produced; and a method using this arrangement. It may be provided a filter and / or separation system, preferably in the fluid circuit. It can be provided that the filtering and / or separating system comprises at least one sieve, preferably in the cooking chamber drain, in particular in the bottom of the cooking chamber, and / or in the intake region of the pump. The filtering and / or separating system may comprise at least one sieve, preferably in the cooking chamber drain, in particular in the bottom of the cooking chamber, and / or in the intake region of the pump. The filtering and / or separating system may comprise at least one cyclone. The filtering and / or separating system may be self-cleaning. The cleaning arrangement may have a regulating and / or control device in operative connection with the shut-off device and / or the filtering and / or separating system. It is disadvantageous that the filter and / or separation system can easily clog and comparatively expensive to clean only by a self-cleaning.
    It is the object of the present invention to overcome the disadvantages of the prior art at least partially and in particular a particularly little clogging, but effective way of filtering liquid in a cooking appliance, especially in a steam oven to provide.
    This object is solved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.
    The object is achieved by a cooking appliance filter insert for a filter container of a cooking appliance with a channel-shaped filter (hereinafter also referred to as "first" filter without limiting the generality) whose side surface is configured as at least a first filter element and its side surface an inner cavity, wherein a first cover (hereinafter also without limitation of generality also referred to as "upper" cover) with at least one first passage opening (hereinafter also without limitation of generality as "upper" passage opening) on a first end face (in The following also applies without limitation to the general public as the "upper" end face) of the first filter and the at least one upper passage opening is fluidically connected to the inner cavity.
    It is thus provided a passage channel which extends from the at least one upper passage opening through the inner cavity and thereby provides no filtering or only a rough restraint of large particles. Liquid can flow out of the internal cavity through its sidewall (not just through the passageway). Thus, an unfiltered liquid can be provided on an outlet side of the flow channel and a filtered liquid can be provided next to the first filter element. While the filtered liquid by means of the large side surface and thus in a large amount can be filtered, larger particles can be removed through the passage channel, without clogging the first filter or the at least one first filter element. The filter element remains relatively clean and does not need to be cleaned frequently. By resting the upper cover on the upper end face (or an upper end edge) of the first filter a particularly compact arrangement is possible. In particular, the at least one upper through opening opens towards the upper end face.
    The at least one upper passage opening is in particular adapted to let through even larger particles which are not passed through the at least one first filter element.
    The channel-shaped first filter may have a channel-shaped or tubular basic shape to the effect that its side wall has a closed shape in the circumferential direction and the upper open end face and a second open end face (hereinafter also referred to without limitation of generality as the "bottom" face ) having. The side wall has the at least one first filter element. Liquid may thus enter through the upper end face in the inner cavity, flow through the inner cavity and unfiltered escape through the lower end face again. Also, particles that can not pass through the at least one first filter element may be entrained or sink through the inner cavity. The inner cavity thus provides the possibility of providing an unfiltered fluidic connection between the upper end face and the lower end face. Liquid may alternatively or additionally enter through the upper end face in the inner cavity and then filtered through the at least one first filter element emerge.
    It is a further development that the cooking appliance is a water-conducting cooking appliance, which provides water as the liquid, possibly with additives such as detergents, etc.
    It is a further development that the upper cover protrudes laterally circumferentially beyond the first filter. Thus, a sufficiently large space for filtered liquid can be provided by simple means, while the upper cover element can seal the filter container on the edge so far that a parasitic by-pass of unfiltered liquid can be strongly suppressed or even prevented in this space. The upper cover may like this edge have a seal.
    It is still a further development that the filter cartridge is provided for operation in a position in which the channel-shaped first filter, in particular its inner cavity, at least substantially aligned vertically. An at least substantially vertical orientation may be understood to mean, in particular, a precisely vertical orientation as well as an orientation with an inclination angle of, for example, up to 22.5 °, in particular of up to 10 °, in particular of up to 5 °. Thus, particles can float freely through the open cavity without settling on at least one first filter element.
    It is an embodiment that the upper cover is liquid impermeable except for the at least one upper passage opening.
    It is an alternative embodiment that the upper cover is formed as a second filter with at least one second filter element and at least a portion of the at least one second filter element is disposed fluidly adjacent to the at least one first filter element. This provides the advantage that a filter performance of the filter cartridge is increased. The fact that at least a part of the at least one second filter element is arranged fluidly adjacent to the at least one first filter element comprises in particular an arrangement in which fluid, then filtered, passes through this part of the second filter element to a volume outside the first filter element. Thus, a double filtering can be avoided, which would reduce the filter throughput. In particular, the liquid filtered by the first filter and the second filter may flow together, in particular into a common space or into a common volume.
    It is still an embodiment that the second filter has a plate-like or disk-like basic shape. Such a filter is particularly easy to produce and allows a particularly compact design. However, for example, the second filter may also be curved, e.g., cupped.
    It is a further embodiment that the at least one upper passage opening is arranged centrally in the upper cover, in particular the at least one second filter, in particular centrally in the at least one second filter element. Thus, a direction-independent arrangement of the filter insert can be facilitated.
    It is still a development that the at least one first and / or the at least one second filter element are adapted to retain solids from the liquid. The at least one first and / or the at least one second filter element may be in the form of at least one sieve, e.g. a metal mesh, be formed, which allows a particularly long life and easy cleanability.
    The at least one first filter element and the at least one second filter element may have the same or different filter properties. By a filter characteristic may be understood, for example, a retained minimum particle size, a throughput capacity and / or a filter efficiency.
    The at least one first and / or second filter element may each be formed as a single filter element or as a plurality of filter elements. The plurality of filter elements may be held by a support structure such as a support frame, for example. If several filter elements are present, these can also be referred to as filter segments.
    It is yet another embodiment that the filter insert a second cover (hereinafter also without limitation of generality as a "lower" cover member), in the at least one second passage opening (hereinafter without limitation of the generality as "lower »Passage opening referred) is introduced, which lower passage opening is fluidly connected to the inner cavity. The lower cover allows mechanical fixation of the first filter, providing a foot, and easy and robust mechanical positioning in the filter container. The lower cover is arranged in particular on the lower end face.
    It is a further development that the lower cover rests on the first filter so that the at least one lower passage opening opens to the lower end face of the first filter out, especially when the upper cover rests on the upper end face. The lower cover may be liquid impermeable to reduce unwanted fluid bypasses except for the at least one lower passage opening.
    It is a further development that the lower cover member has a plate-like or disk-like basic shape. Such a lower cover is particularly easy to manufacture and allows a particularly compact design. However, for example, the lower cover member may also be curved, e.g., cupped.
    It is furthermore an embodiment that the at least one first filter element has a cross-sectional shape which changes its curvature direction several times in the circumferential direction. Thus, compared to a circular or ova len cross-sectional shape, which always has the same direction of curvature, larger filter area and thus provide even lower tendency to clogging and a higher throughput. The repeatedly changing direction of curvature may be implemented, for example, by a wavy cross-sectional shape or a cross-sectional shape bent several times in different directions. In particular, the cross-sectional shape may be a star shape with straight neighbor sections that are inclined towards one another.
    It is also an embodiment that the at least one upper passage opening is covered by a coarse grid. Thus, particularly large particles which could possibly settle in the inner cavity of the first filter can be retained.
    It is a development that on the filter element, in particular on the second filter, at least one handle device for simplified handling, in particular gripping, of the filter element is present, e.g. one or more upright tabs.
    It is still a further development that the filter insert, in particular the lower cover, at least one attachment means for attachment in the filter container. The at least one fastening device may, for example, have one or more projections and / or recesses for producing a latching connection or a plug-in / rotary connection with the filter container. Additionally or alternatively, the attachment means may comprise one or more spring elements, e.g. for producing a releasable latching connection, in particular clip connection, with the filter container. The filter insert may also be screwed into or with the filter container.
    In addition, a filter container of a cooking appliance is disclosed, which is adapted for receiving a filter cartridge as described above and having a cup-like basic shape with an upper-side insertion opening, a bottom and an attached to the bottom circumferential side wall, wherein the filter container comprises: one in the Floor existing first drain opening (hereinafter referred to as "bottom" drain opening without restriction of the general public), leading to a lockable storage volume and a present in the side wall second drain opening (hereinafter also without limitation of generality as "lateral" drain opening referred to). The lateral drain opening may in particular be fluidically connected to the at least one first filter element and, if present, to the part of the at least one second filter element arranged next to the first filter element. The filter container can be configured analogously to the filter insert and has the same advantages.
    Such a filter container has the advantage that arrive at the filter insert and then descend through the passage channel larger particles pass through the lower drain opening in the lockable storage volume and can be stored or deposited there. The storage volume thus serves as a particle trap from which these particles can advantageously no longer get back into the filter container. By unlocking or opening the storage volume, the particles deposited therein can be removed from the filter container. The filter container and the filter cartridge are therefore not or only to a small extent covered by larger particles or clogged.
    From the side drain opening, the liquid filtered through the filter cartridge can be drained, e.g. are sucked, for example, for use as a working fluid. In this case, the side wall of the filter container, possibly together with the arranged next to the first filter part of the second filter element, with the side surface of the first filter and the bottom of the filter container or with the lower cover of the filter insert a space, a volume or a reservoir for the filtered liquid.
    The filter container may also be referred to as a "filter holder".
    It is still a further development that the filter insert is aligned at least substantially vertically when used in the filter container.
    It is an embodiment that the filter insert in the filter container by means of a plug-in / rotary connection can be fastened. Thus, a secure fit with easy usability and removability of the filter insert can be combined. The plug / turn connection may be a kind of a bayonet connection, for example.
    It is an alternative development that the filter cartridge in the filter container by means of a clamping connection of a releasable locking connection (for example by clipping) or alone by its weight is durable.
    The object is further achieved by a cooking appliance, comprising a arranged at a bottom of a cooking chamber filter container as described above, in which a filter cartridge is used as described above. The cooking appliance can be designed to be analogous to the filter container and to the filter insert and has the same advantages.
    The cooking appliance as a water-conducting cooking appliance may in particular be a steam-generating cooking appliance, e.g. a steam oven.
    It is a development that the cooking appliance is a household appliance, in particular a kitchen appliance, e.g. in the sense of so-called "white goods" for private households. The cooking appliance may be a large household appliance.
    It is an embodiment that a drain of the cooking appliance with the lockable storage volume and the lateral drain opening are fluidically connectable with at least one liquid utility of the cooking appliance, in particular alternately. The content of the storage volume, including the particles deposited there, can be promoted in an emptied removal container of the cooking appliance or removed from the cooking appliance. The liquid utility may reuse the filtered water in the cooking appliance.
    It is a development that the Flüssigkeitsnutzeinrichtung is a cleaning device. This may e.g. a cooking chamber cleaning device, by means of which a wall or walls of the cooking chamber (possibly including a door) can be cleaned, e.g. a spraying device, e.g. comprising one or more spray nozzles. Consequently, the cooking chamber can be sprayed with filtered through the filter cartridge liquid. The spraying device may in particular be arranged on a ceiling of the cooking chamber.
    It is a further development that the lateral drain opening can be connected to the liquid utilization device, in particular cleaning device, via a pump. Thus, pressurized liquid can be provided to the liquid utility device.
    In particular, the filter cartridge may form part of an at least predominantly closed fluid circuit. The liquid circuit may, for example, liquid (in particular water) filtered from the filter container through the side drain opening of the filter container, through the pump, through the cleaning device, on the walls of the cooking chamber, from there flowing down to the ground and at the bottom to the filter container to circulate fluidly ,
    For example, such a liquid circuit may be operated as part of a cleaning program of the cooking appliance, possibly with the addition of detergent, descaling or the like. During the circulation of the liquid in the liquid circuit, the storage volume is preferably shut off. With the completion of the liquid circuit, liquid still draining from the walls of the cooking chamber collects at least part of the coarse and fine particles resting on the upper cover element, in particular the second filter, thereby detaching it. If the storage volume is now opened, the liquid flows out of it and draws off the water in the filter container and the water above the filter insert, above all through the non-filtering flow channel. The resulting flow is sufficient to pull floating particles through the flow channel. The flow may also be sufficient to at least partially entrain particles located on the inside of the first filter.
    It is also an embodiment that the pump is fluid-permeable in an inactive state. Thus, when the pump is stopped, previously filtered fluid may flow back through the pump, e.g. liquid in a liquid line. This back-flowing liquid presses into the space or reservoir for the filtered liquid and thus against the portion of the second filter element (if present) adjacent the first filter and against the first filter element in the opposite direction to a filtering function. Thus, adhering to these filter areas particles can be solved. These particles can either sink in the direction of the storage volume or be pulled there due to the flow when the storage volume is open. The pump may in particular be switched off before or with an opening of the storage volume.
    The above-described characteristics, features and advantages of this invention, as well as 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 is explained in more detail in conjunction with the drawings.
    Fig. 1 shows a sectional side view of an inventive cooking appliance;
    Fig. 2 shows an oblique view of a filter element for the cooking appliance; and
    Fig. 3 shows a sectional view in an oblique view of a section of the cooking appliance in a region of a filter container with inserted filter insert.
    Fig. 1 shows a water-conducting cooking appliance in the form of a steam oven D. The steam oven D has a cooking chamber G, which is surrounded by a cooking chamber in the form of a furnace M muffle. The cooking chamber G has on the front side a charging opening W, which can be closed by means of an oven door T. The cooking chamber G can be heated by means of at least one heating element (for example a top heat radiator, bottom heating radiator and / or a heating air radiator, not shown). The cooking chamber G is also acted upon by steam, for example by means of a steam generator arranged outside the oven muffle M, by means of an atomizer, etc. (not shown).
    A bottom B of the oven muff M has a recess on which a filter container F is arranged. The filter container F is designed to receive a filter insert 1. Liquid L present on the bottom B flows into the filter container F. The filter container F is cup-shaped with an upper-side inflow opening I opening into the cooking chamber G, a bottom Bd with a first, lower discharge opening O1 present there and one extending from the bottom Bd in the direction of the influence opening I extending side wall Sw.
    In the side wall Sw a second, lateral drain opening 02 is present, which leads via a first liquid line R1 to a suction side of a pump P whose pressure side leads via a second liquid line R2 to a arranged on a cover Dk the oven muffle M spraying device A. , The spraying device A serves to spray the liquid L under pressure on the oven muffle M and an inside of the oven door T in order to clean it. The spraying device A thus represents a cleaning device.
    The lower drain opening 01 leads into a storage volume S arranged underneath, which can be shut off via a valve V. The valve V may be connected downstream with an outlet Af of the steam oven. The drain Af may lead directly out of the steam oven D or may lead into a removal tank (not shown) of the steam oven D.
    The heating elements, the steam generating device, the pump P and the valve V can be actuated or activated by means of a control device C. The control device C may, for example, control a cleaning process for cleaning the oven muffle M and possibly the oven door T.
    Without consideration of the filter element 1 inserted into the filter container F, for example, at the beginning of a cleaning process, for example, cleaning agents could first be applied to the bottom B of the cooking chamber and then liquid L, e.g. in the form of fresh water. At least part of the liquid L in the form of water mixed with the cleaning agent flows into the liquid container F and into the storage volume S. The valve V blocks, so that the liquid L can not continue to flow there initially. Subsequently, the pump P can be activated, which sucks the liquid L through the lateral discharge opening 02 from the filter tank F and presses to the spraying device A. The spraying device A generates one or more cleaning jets, in particular spray jets, in order to clean off the oven muffle M and optionally the oven door T. She likes to do this, e.g. have one or more nozzles. The liquid L then added with cleaned particles passes from the oven muffle M and possibly the oven door T down to the bottom B and from there back to the filter container F. This liquid circuit is indicated by the open arrows. Without inserted filter or filter cartridge 1, the cleaned particles can impair the operation of the pump P and / or clog the spray device A.
    If the actual cleaning process is completed, the pump P can be stopped, for example. Since the pump P is fluid-permeable in a stopped or inactive state, the liquid L in the lines R1 and R2 and in the pump P flows back in the direction of the filter container F.
    By the following unlocking of the valve V, the liquid L can be drained.
    Fig. 2 shows an oblique view of the filter cartridge 1. Proves a first, "upper" cover in the form of a circular disk-shaped second filter 2. The second filter 2 consists of a circular disk-shaped second filter element 3, which centrally has a circular upper passage opening 4. A web 5 crosses the upper passage opening 4 and serves as a coarse grid for keeping particularly large particles.
    The filter element 1 further comprises a tubular or rectilinear channel-shaped first filter 6, the first filter element 7 (as the only component) has a rotationally symmetrical, star-shaped and closed about its longitudinal axis circumferential cross-sectional shape Q, as indicated by the dotted line. The cross-sectional shape Q thus changes its direction of curvature in the circumferential direction about a longitudinal axis several times, wherein adjacent straight sections are connected to one another via bending or bending lines. The first filter element 7 is connected at its outer tips 8 to the second filter element 3.
    The first filter element 7 surrounds as a side wall or side surface an elongated inner cavity 9, which is covered at its first, upper end face 10 of a small part of the second filter element 3 and of the upper passage opening 4. The upper passage opening 4 opens to the upper end face 10 of the first filter element 7, so that the inner cavity 9 is fluidly connected via the upper end face 10 with the upper passage opening 4.
    Thus, while a small part of the second filter element 3 is located within the upper end face 10, by far the largest part 11 of the second filter element 3 lies laterally outside and thus fluidly adjacent to the upper end face 10 or fluidly next to the first filter element 7.
    A second, lower end face 12 of the first filter element 7 is covered by a second, lower cover member 13 with circular disk-like basic shape, which also serves as a foot of the filter cartridge 1. The lower cover member 13 has centrally a lower passage opening 14, which opens into the lower end face 12 and is otherwise for the liquid L, for. impermeable. The inner cavity 9 connects the upper passage opening 4 with the second passage opening 14 fluidly.
    For fastening the filter insert 1 in the filter container F, the second filter 2 has on the edge side two upright tabs 15 as handling means, e.g. for rotating and pulling the filter cartridge 1. The lower cover member 13 has two peripheral recesses 16, e.g. for the implementation of a plug / turn closure with the filter container B. The second filter 2 may have a seal 17 at the edge.
    Fig. 3 shows a sectional view in an oblique view a section of the steam oven D in a region of the filter container F, in which now the filter element 1 is inserted. The filter container F is made in two parts with a first part Fa and a second part Fb. The second part Fb is inserted into the first part Fa, e.g. screwed with it, and sealed by a circumferential ring seal Di to avoid parasitic side streams of liquid L. The two-part construction simplifies manufacture and assembly of the filter container F.
    The second filter 2 of the filter element 1 closes the influence opening I of the filter container F largely dense, so that liquid can flow only through the second filter 2 and not between the second filter 2 and the Filterbe container F. The filter element 1 is by means of a plug / Rotary connection, in particular a bayonet closure, in the filter container F attached.
    The side wall Sw of the filter container F, together with the next to the first filter 6 arranged part 11 of the second filter element 3, with the first filter element 7 and with the lower cover 13, a space Z for filtered fluid F is the pump is P for a cleaning operation in operation, which is formed here in the form of a siphon memory reservoir S filled with the liquid L. Therefore, the liquid L flows substantially either through the next to the first filter 6 lying part 11 of the second filter element 3 or through the inner cavity 9 and through the first filter element 7 into the space Z. From there, the thus filtered liquid L is through the side drain hole 02 and the first liquid line R1 are sucked to the pump P. The sprayer A can not clog so.
    Larger particles located in the liquid L are drawn by the suction of the liquid L into the inner cavity 9 and float there, if they are heavier than the liquid L, through the lower passage opening 14 and lower drain opening 01 into the storage reservoir S, which also serves as a storage place or as a quiet zone for the floated particles. The lower drain opening 01 is thus downstream of the lower passage opening 14 fluidly. Lighter particles float in the region of the inner cavity 9 or above it.
    When the pump P is turned off, filtered liquid L pushes back into the space Z and now flows back against the (in the operation of the pump P maintained) filter direction through the part 11 of the second filter element 3 and through the first filter element 7. In this case, 11 and 7 retained by this filter areas fine particles are dissolved. With the following opening of the valve V, the liquid L now flows substantially through the inner cavity 9 and through the storage reservoir S. The associated flow takes both larger, deposited in the storage reservoir S particles as well as bloated larger particles. In addition, the recently detached fine particles are taken and removed. The pump P and the valve V can thus be controlled so that the filter container F fluidly alternately with a drain of the steam oven D or with a cleaning device, namely the spray A of the steam oven D, is connectable.
    Of course, the present invention is not limited to the embodiment shown.
    Generally, "a", "an", etc. may be taken to mean a singular or a plurality, in particular in the sense of "at least one" or "one or more", etc., unless explicitly excluded, e.g. by the expression "exactly one", etc.
    Also, a numerical specification may include exactly the specified number as well as a customary tolerance range, as long as this is not explicitly excluded.
