Description

The invention relates to an electric motor-driven food processor with a mixing vessel and a lid for the mixing vessel, wherein the lid has a passage opening and the through opening, a cover is assignable, wherein the cover completely covers the passage opening.

Food processors of the type in question are known. These are used, in particular, in the household sector for the preparation or preparation of food, for which purpose an electromotive drivable agitator is provided in the mixing vessel. The drive of the agitator is in this case provided in the food processor, for which purpose the mixing vessel preferably has a corresponding coupling formation on the bottom side. Such stirring vessels are more particularly in operation, i. continue in the operation of the agitator lid closable, and it is further known in this regard to lock the lid in the closed position. In a known manner, the lid has a passage opening through which, for example, in the course of the preparation of a food ingredients can be supplied. In particular, in the course of a stirring and / or a cooking process, with a corresponding arrangement of a heater or training of the mixing vessel with a heated vessel bottom, it proves useful to cover the cover-side passage opening, thereby counteracting in particular a splashing out of liquids from the mixing vessel. For this purpose, as known from the prior art, a cover, which is the through hole assignable and in the assignment position, the through hole preferably completely covers. Known cover parts are further formed so that they are not fixed to the lid, for example. In the sense of a snap or snap connection. Thus, it is in particular the user allows, even during a cooking process without difficulty lift the cover to hereafter by the exposed passage opening, for example, other ingredients, such as in particular spices or the like, the cooking process supply.

A food processor of the type in question is known for example under the trade name "Vorwerk Thermomix".

In view of the known prior art, a technical problem of the invention is seen in a kitchen appliance of the type in question in particular handling technology to improve.

A possible solution of the problem is given according to a first inventive concept in a food processor, which is geared to the fact that the bottom of the cover in overlapping the lid in a circumferentially limited area by spaced course of the cover bottom underside to a top cover a steam flow path forms and that the cover engages in the passage opening. A cover part is accordingly provided which almost completely closes off a space which optionally exists between the cover top side and the cover part, with the exception of a selectively kept steam throughflow path. The latter is provided in a circumferentially limited area in the cooperation region of the cover and lid. Accordingly, in the cooperative position of the cover part and the mixing vessel lid, a targeted, more preferably directed steam throughflow path is provided, which, according to the circumferentially spaced profile, is correspondingly formed in a peripheral region of the mixing vessel lid to form the throughflow path. This advantageously makes it possible to align the steam flow path, in particular depending on the circumferential orientation of the cover on the mixing vessel lid so that in operation optionally outflowing steam not on equipment parts and / or in the vicinity of the food processor located objects and / or in Direction of the user or by the user to be operated device parts is directed. Thus, in a further preferred circular disc-shaped configuration of the lid or the top side and corresponding substantially circular disk-shaped configuration of the cover according to placing and rotating the cover on the lid allows a corresponding orientation of the steam flow path in the desired direction. As a result of the preferably complete covering of the passage opening of the lid, liquids which have been accelerated in the mixing vessel by means of an activated stirrer and possibly pass through the passage opening of the lid are not forwarded directly to the environment. Rather, a labyrinth-like cover is achieved by the proposed design and arrangement of the cover. The cover member is circumferentially with the exception of the area forming the steam flow-through preferably completely on the top side of the cover, wherein more preferably the cover rests alone with its own weight on the lid. In a preferred embodiment, the cover engages at least with a partial section in the passage opening of the Gargefäßdeckels, this more preferably under appropriate centering effect. This engagement section preferably merges into the steam flow-through path, in a preferred embodiment it ensures that steam emerging from the cooking vessel is not under the cover part, ie. H. continues to flow between cover and lid of the cooking vessel outside the steam flow path.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 or with features of further claims. But they can also be in an assignment to only individual features of claim 1 or the respective further claim or each independently of importance.

Thus, it is further provided in a preferred embodiment that the lid forms a circumferential bead and that the cover has a cooperating with the edge bead engagement projection. In this case, the edge bead preferably extends, starting from the upper side of the cover, at least essentially vertically upwards, correspondingly preferably completely encompassing the surface of the upper side of the cover. The cover part preferably engages with an engagement projection in the area encompassed by the edge bead, more preferably with radial support of the engagement projection on the inside of the edge bead. In a preferred circular disk-shaped configuration of the cover member as a whole, the engagement projection, optionally interspersed by the steam flow-through path, is also preferably circular-disk-shaped in plan.

The steam flow-through is in a preferred embodiment vertically upward as well as circumferentially viewed laterally bounded by portions of the cover, while a limitation to vertically down particularly in the coverage area to the lid by the lid itself, in particular by the edge bead and / or the Cover surface is formed. In a further embodiment, it is provided that the steam flow-through path is formed radially outwardly in relation to a peripheral edge of the cover part otherwise extended and at least partially formed closed down in the extended area. In this regard, it is preferably further provided that this extended region is extended outwards via a peripheral edge of the lid and / or the mixing vessel which extends radially outward. As a result of the closed-down design of at least the extended region, moreover preferably of the area adjoining radially outward in overlap with the edge bead of the lid, a directed outflow of the steam emerging from the stirring vessel is directed outward, in particular radially outward and more preferably in this case at least tends to be sideways or upwards. An evaporation to tend vertically below, especially in the immediate edge region of the mixing vessel is prevented by the bottom-side closed design of Durchströmweges.

In addition, it is preferred that the downwardly closed region is formed radially inward to cover the passage opening of the lid. Furthermore, the closed region is preferably designed to increase radially outwards, in particular enclosing this at an acute angle of 5 to 45 °, more preferably 15 to 30 ° to a parallel plane to the opening plane of the stirring vessel. The slope here is preferably chosen to be the same throughout. Alternatively, different slopes are provided over the course of the Durchströmweges from radially outside to radially inside in the direction of the passage opening sections.

In a further preferred embodiment, the cover has a Zuführausformung reaching to the passage opening of the lid. This is used in particular for supplying, for example, fluids or granular goods, which are to be supplied to the cooking process in the mixing vessel, such as oils or spices. For the appropriate addition of such ingredients, the cover is in a user-friendly manner to release the passage opening in the lid not necessarily lift. Rather, the Zuführausformung is usable for this purpose. The Zuführausformung is in one embodiment separately from the steam Durchströmweg, for example provided in circumferentially offset position to this, more preferably under schüttenartiger embodiment starting from the end opening to be assigned to the end portion radially outwardly increasing. Preferably, the Zuführausformung radially projects beyond a peripheral edge of the cover for the formation of a freely accessible from the outside inlet or Aufstreuabschnitts for ingredients.

In this respect, it is further preferred that the steam flow-through path can also be used as a feed-out formation. This is advantageously the use of the steam Durchströmweges at the same time as Einführweg particular for during the cooking or stirring process in the mixing vessel to be entered ingredients, such as liquids or granular ingredients, such as further spices, for example. The downwardly closed and preferably up to the passage opening of the lid extending portion of the Durchströmweges is preferably used like a spill here to promote the ingredients targeted through the passage opening of the lid in the cooking chamber. Further preferred in this context is the arrangement of lateral boundary walls, in particular of the over the peripheral edge of the cover protruding portion of the steam Durchströmweges.

In particular, for the addition of fluids, the Zuführausformung is in a further preferred embodiment on the filler side with an upward provided open metering pot, which further preferably has a bottom-side outlet opening. The outlet opening here preferably serves to influence the feed rate of the fluid introduced into the metering pot. The metering pot in this case preferably has a receiving volume of 20 to 100 cm ³ .

In addition, the dosing pot is preferably designed to open vertically above, alternatively providable with a lid. The outlet opening is in the allocation position of the metering pot to the feed formation in the direction of the feed outfeed, i. is directed towards the central passage opening of the lid, wherein more preferably the dosing pot has a sloping to a central region of the cover back, further in particular in this case having a tendency corresponding to the Zuführausformung, moreover, preferably the inclination of the steam Durchströmweges.

Particularly advantageous is an embodiment in which the radial extension of the steam Durchströmweges is given by an insertable feed part, which forms the Zuführausformung correspondingly with insertion of the feed part in the steam flow-through. The feed part is preferably inserted only for the purpose of adding ingredients in the cooking vessel, while in usual cooking process for the directed discharge of the steam, the feed part is removed from the steam flow-through, although the steam Durchströmweg is not closed by the feed, according to also inserted feed acts. Preferably, in this case, the feed part in the steam flow-through from radially outside to radially inside inserted, more preferably, the insertion depth is adjustable. The determination of the feed part is preferably carried out solely on the basis of frictional engagement, moreover, as an alternative, according to a detent fixing, optionally by a stepwise detent fixing.

In a food processor of the specified type, a weighing device is furthermore preferably provided, more particularly in the bottom region of the food processor, via which weighing device, in particular, the quantity of food to be added or the like to be added into the mixing vessel can be measured. The patch on the cover of the mixing vessel cover provided in a preferred embodiment, after vertically directed upper side on a bearing surface on which is to be weighed Good can be stored. The support surface is hereby preferably flat, but may also be formed at least inwardly bowl-like inclined.

With regard to the disclosure, the ranges and / or ranges of values or multiple ranges given above also include all intermediate values, in particular in 1/10 increments of the respective dimension, if necessary also dimensionless, in particular 1.01-fold etc. on the one hand to limit the mentioned range boundaries from below and / or above, alternatively or additionally but also with regard to the disclosure of one or more singular values from the respective specified area.
