DESCRIPTION

Closing element for the preparation container of a kitchen machine, preparation container and kitchen machine

Field of the invention

The invention relates to a closure element for a preparation container of a kitchen machine, to a preparation container for a kitchen machine with a closure element, as well as to a kitchen machine with a preparation container with a closing element.

State of the art

From the state of the art, kitchen machines are known which have a preparation container. It serves to house the food prepared with the kitchen machine during its preparation. In some of these kitchen machines the preparation container can be heated. This makes it possible not only to prepare the food preparations produced with the kitchen machines mechanically with such kitchen machines, but also the food preparations can be heated at the same time. For example, it is thus possible to prepare also foods that must be heated in their preparation, instead of only food preparations, such as cake doughs, which can be prepared without an essential change in temperature. In particular, food can also be cooked in such a container.

Kitchen machines of this type generally have a construction in which a preparation tool for the mechanical preparation of food is arranged inside a preparation container. The brewing vessel can be heated, for example, heating elements may be provided in the brewing vessel. An electrical contact of the preparation container with the kitchen machine then enables these heating elements to be used to heat the preparation container. In the case of the tool, it can be in particular a mixing blade and / or a stirring device.

To mechanically actuate the tool, it is common in kitchen machines of this type for the preparation containers to have an opening through which the The tool is connected by means of a mechanical transmission element, such as, for example, a shaft, with an electric motor arranged in the kitchen machine. The kitchen machines, in particular the preparation containers and / or the preparation tools, are designed in such a way that in the operating state of the kitchen machine the exit through the opening of the food which is drawn is prevented. prepare. In particular, a sealing of the opening can be effected by the preparation tool when the preparation tool is housed in a corresponding housing of the preparation container, which also regularly forms the opening.

However, in kitchen machines of this type with a preparation container it is disadvantageous that the tool proves to be cumbersome when it comes to heating food only in the preparation container, without having to undergo mechanical processing by the tool. The tool then occupies a space in the preparation container of the kitchen machine that could be used without the presence of the tool in the preparation container for the accommodation of food. In this regard, the tool is particularly cumbersome, because it requires a space in the area of the bottom of the preparation container that could be used, in particular with chopped foods, such as pieces of meat, in a particularly advantageous way for placement. of food in the prep container.

Description of the invention

Therefore, the invention is based on the objective of improving a conventional kitchen machine with a preparation container in such a way that it is better suited to heating food without processing the same at the same time.

The object is achieved by a closure element for a preparation container of a kitchen machine, by a preparation container for a kitchen machine, as well as a kitchen machine having the features of the independent claims. The features of the dependent claims relate to advantageous embodiments.

The closure element for a preparation container of a kitchen machine has a cover area for covering an opening in the preparation container and a zone of introduction to introduce the closure element in the opening. The zones can be zones of a one-piece component of the closure element, however, in the case of the cover zone and the insertion zone, they are advantageously individual parts connected to one another. The cover area serves to cover the opening. To fulfill this purpose, the cover area advantageously has an at least substantially disc-shaped design. By an at least substantially disc-shaped design in particular it is to be understood that the thickness of the cover area is substantially less than its extent in the direction orthogonal to the thickness direction of the cover area.

The cover area can have a round profile projecting in the direction of the thickness direction. In this regard, the diameter is advantageously selected larger than the diameter of the opening in the preparation container. In this way, the cover area makes it possible to reliably close the opening in the preparation container, generating only a minimal need for space inside the preparation container.

The cover area can be made of metal. Metallic materials have good thermal, chemical and mechanical resistance. In particular, the cover area can be made of stainless steel. Stainless steel has excellent chemical resistance to substances that can normally be contained in food, and it is also easy to clean.

The insertion zone can be attached to a surface side of the cover zone. This position makes it possible in particular for the insertion zone to extend away from the surface side of the cover zone. In this way, the insertion zone can be inserted into an opening of a preparation container of a kitchen machine, in which at the same time the cover zone, with the surface side to which the insertion zone is attached, can reach the sealing support at the bottom of the preparation container or a sealing element arranged between the bottom of the preparation container and the cover area.

Projected in parallel in the direction of the thickness direction of the cover area, the profile of the insertion area in particular has a smaller diameter than the cover area. This applies in particular to the larger diameter of the projected profile in the thickness direction of the cover area of the cover area. introduction, if the profile of the introduction zone in this projection has different diameters. In this way, it can be ensured that it is possible to insert the insertion zone into the opening and at the same time ensure a support of the cover zone on the bottom of the preparation container, optionally with a sealing element arranged between them.

The insertion zone can be fixed in the cover zone by means of a fixing element inserted in the direction perpendicular to the surface side through the insertion zone, in particular by means of a screwed or riveted connection. The fixing element can be fixed to the insertion zone. Alternatively, it is possible to configure the fixing element in one piece with the cover area. Thus, the fixing element can have a thread into which a nut is screwed to fix the insertion zone to the cover zone. Alternatively, it is also possible to produce a riveted joint by guiding a fastening element made, in particular, in one piece with the insertion zone, through the insertion zone and deforming it on the guided end through the insertion zone. In particular, the fixing element can be deformed by wobbling. By wobbling, a deformation of the fastener is generated which results in a thickening of the guided end through the insertion zone. It can prevent the insertion zone from detaching from the cover zone. In this way, an inexpensive, durable, as well as strong connection is generated between the insertion zone and the cover zone.

The introduction zone can be subdivided into sub-zones. They can be arranged consecutively, in particular in the thickness direction of the cover area. Sub-areas of this type facilitate the production of a contour of the surface of the insertion area that is notched. A contour of the insertion zone can, for example, prevent a rotation of the insertion zone in the opening, in particular when the opening or the housing has a corresponding complementary contour. A corresponding contour may also be used, for example in projecting protrusion design, to hold the closure member in its housed position.

Advantageously, it is possible for the sub-zones to be held together by the fixing element, with which the insertion zone is fixed in the cover zone. In this way, the fixation of the insertion zone can be carried out in a simple way. in the roof area, as well as the connection of both sub-areas of the introduction area in a single work stage. In particular, both sub-zones can be placed consecutively on the fixing element.

The sub-areas may be protected, by means of complementary nesting contours, against rotation with respect to one another about an axis parallel to the direction of insertion. The insertion direction is in particular parallel to the thickness direction of the cover area. In this way, both sub-areas can have contours that cooperate as protection against rotation and / or to hold the closure element in the housing with other elements of the kitchen machine, without causing the sub-areas to rotate one with respect to to another, which could affect the function, in particular that of the restraint.

Such subzones can be produced in an injection molding process and / or from plastic.

By means of the sub-zones, it is possible to achieve an insertion zone having notches, without the need for a mold that is suitable for producing notched components, for example a mold having push elements. Instead, for each sub-zone, a mold of its own, designed in a substantially simpler way, can be used. This is advantageous in terms of production costs in particular up to a certain series size.

In an alternative and / or complementary way, a more complex mold, for example a mold with push elements, can be used, in particular when a correspondingly large number of notched insertion zones are to be produced, however also a more complex mold, for example a mold with push elements, in order to be able to produce one piece the introduction area. In such a case, the lesser complexity for the assembly of the one-piece insertion zone can overcompensate in the cover zone for the additional costs of the more complex mold and thus enable a more economical production.

The cooking machine's preparation container is used to house food during preparation. It has a housing to accommodate a preparation tool for mechanical food preparation, for example a stirring tool or a mixing blade. Through the housing, an opening is formed in the bottom of the preparation container. When none is hosted preparation tool in the housing, there is therefore a risk that food will come out through the opening out of the preparation container.

The preparation container has a closure element. In the case of the closure element, it may be a closure element with the characteristics described above. The closure element can be housed in the housing, in order to close the opening in such a way that the bottom of the preparation container, including the opening closed by the closure element, can be used as a supporting surface for food. In this way, by closing the hole in the bottom of the preparation container, a preparation container can be achieved which is more suitable for types of food preparation in which no mechanical preparation of the food takes place with the preparation tool. . Only in preparations of this type would the preparation tool be cumbersome, since it would require a part of the bottom of the preparation container and would block its use as a support surface for food. In particular, when the preparation tool is arranged in the center of the bottom of the preparation container, the preparation tool represents a troublesome impediment in practice.

The closure element may in particular be configured to be inserted along an insertion direction into the opening of the preparation container. In this connection, the insertion direction can be oriented in particular perpendicular to the bottom of the preparation container. In particular, when the insertion direction is oriented equally parallel to the thickness direction of the cover element, a flat supporting surface for food can thereby be achieved in relation to the cover element described above, in particular also in the central area of the bottom of the preparation container.

The preparation container may have a holding element for holding the closure element housed in the housing. Such a holding element offers the advantage that the closure element during handling with the preparation container remains fixedly in the housing. For example, the holding element can be designed in such a way that it is movably fixed in the preparation container. In this regard, the clamping element can move in particular between a clamping position, in which the closure element is clamped in the housing, and a release position, in which the closure element can be released from the housing. For example, the fastener may rotate about an axis parallel to the direction of introduction. The clamping element can cooperate with the closure element, in particular in the manner of a bayonet closure. In this case, the clamping element is designed, in particular, in such a way that with a movement from the release position to the clamping position it engages the projections on the closing element from behind, in particular in the area of insertion of the closing element.

The housing, in particular the opening, in the area of the bottom of the preparation container can have a contour that cooperates with a complementary contour of the holding element in such a way that a rotation of the closure element housed in the housing is prevented relative to the brew container. In particular, a rotation of the closure element relative to the bottom of the preparation container about an axis parallel to the insertion direction is prevented. The contour of the clamping element can, for example, consist of projections which are regularly distributed around the perimeter of the insertion zone. A corresponding contour of the opening can then cooperate with these projections in such a way as to prevent a rotation of the closing element housed in the housing with respect to the preparation container. This makes sense in particular as regards the fastening of the closure element in the housing. By preventing rotation, hooking behind the projections, in particular by way of a bayonet lock, can be ensured, for example, by the clamping element, without the projections being able to bypass the clamping element by rotating the element. closure and / or the area of introduction of the closure element.

Between the bottom of the cooking container and the closure element, a sealing element can be arranged. The sealing element can in particular be a silicone sealing ring. Silicone sealing rings are inexpensive and particularly resistant to heat. The sealing element can be arranged in particular between the cover area and the bottom of the preparation container. Such a sealing element makes it possible to seal the opening with the closure element.

In particular, the clamping of the closure element with the clamping element causes a tightening of the sealing element in a direction parallel to the insertion direction. In this way, the sealing effect is further improved, furthermore the elastic reaction force of the tight sealing element can be used to hinder an undesired release of the fastening element, that is, an undesired movement of the fastening element out of position. clamping. This makes sense in particularly when the fastening element cooperates with the closure element in the manner of a bayonet closure. Tightening of the sealing element can then be caused by engaging behind corresponding projections on the closing element by means of the clamping element. In this connection, the contours, which cooperate in the manner of a bayonet lock, are designed in particular such that when the clamping element is moved into the clamping position, a maximum of the pressure exerted on the sealing element is exceeded. This maximum must be exceeded again when moving the clamping element to the release position, so that due to the force necessary for this when moving the clamping element to the release position an unwanted movement of the clamping element to the position is hindered. release.

The kitchen machine has a preparation container. In this regard, it may in particular be a preparation container described above. In addition, the kitchen machine features a preparation tool for mechanical food preparation. In the case of this preparation tool, it can be in particular a stirring tool and / or a rotating mixing blade. The brewing tool can be housed in a recess in the bottom of the brewing container in such a way that it protrudes from the bottom of the brewing container upward into the brewing container.

The kitchen machine also has a closing element. The closure element may be a closure element described above. The closure element can optionally be housed in place of the preparation tool in the housing. In this way, the space in the preparation container that the preparation tool occupies when the preparation tool is housed in the housing, at least in an essential part, can be used for food. The interchangeability of the preparation tool and the closing element makes such a kitchen machine very flexible to use. In this regard, by means of the optional accommodation of either the preparation tool or the closure element in the housing, in each case, optimal conditions for the preparation of the food can be achieved, depending on whether or not mechanical preparation is desired. of food with the prep tool.

Detailed description of some embodiments of the invention

The closure element 10 represented by way of example in FIGS. 1 to 3 has a cover zone 12 and an insert zone 14. The cover zone 12 may be designed in the shape of a disk as in the example shown. In order to fix the insertion zone 14 in the cover zone 12, the closure element 10, as in the example shown, can have a fixing element 16 which can preferably be configured as represented in one piece with the cover zone 12. The closure element can also have a sealing element 18, which can be, as shown, a silicone ring. As can be recognized in the example shown in particular in FIG. 3, the insertion zone 14 can be formed by two sub-zones 20, 22. The sub-zones 20, 22 can have complementary contours that interlock with each other in such a way as to prevent a rotation of the sub-areas 20, 22 with respect to one another about an axis parallel to the insertion direction Z. For technical reasons of representation, only the outline of the sub-area 22 is visible in FIG. 3.

As in the example shown, the insertion direction Z can be parallel to the thickness direction of the cover area 12. Furthermore, as can be well recognized in particular from the joint view of Figures 2 and 3, the parallel projection of the profile of the insertion zone 14 in the direction parallel to the insertion direction Z can have a smaller maximum diameter than the cover zone 12. In this way, a complete closure of the opening, into which it is inserted, can be guaranteed. the introduction zone 14.

The insertion zone 14 may have a contour that is designed in such a way that complementary to a corresponding contour of the opening, into which the insertion zone 14 is inserted. Such a contour of the insertion zone 14 can prevent a rotation of the insertion zone introduced into the opening about an axis parallel to insertion direction Z. This makes sense in particular when the insertion zone 14 (as shown in the example shown) has projections 28 which can be engaged behind by a clamping element in a rotary movement about an axis parallel to insertion direction Z. In this way, between the clamping element (not shown) and the closure element 10, a connection can be achieved in the manner of a bayonet closure, with which the closure element 10 can be held in the housing of the preparation container. Advantageously, this can be accompanied by the tightening of the sealing element 18 designed in the example shown as a silicone sealing ring.

The characteristics of the invention disclosed in the foregoing description, in the drawings, as well as in the claims may be substantially both individual and in any combination for the practice of the invention in its various embodiments. The invention is not limited only to the described embodiments. It can be varied within the framework of the claims and considering the knowledge of the person skilled in the art.
