State of the art

Such a food processor is disclosed, for example, in US Pat. No. 2,315,018 A. Further devices for juicing citrus fruits are, for example, US Pat. Nos. 4,744,522 and 2,995,922 A. An accessory for a food processor with a combination of a citrus press and a device for separating citrus fruit Protein and yolk of a raw egg is known from EP 1 917 889 A1. The accessory can be inserted without rotation into a filling opening of a blender lid. The blender includes, among other things, a drive unit on which the bottom side with Mixflüqeln, which are part of the rotor, provided Mix container can be placed. When the mixing bowl is properly placed on the drive unit, the mixing vanes are connected in rotary drive to the drive unit via a coupling. The rotor speed can usually be adjusted in stages or stepless. With attached to the blender container and with citrus fruits can be squeezed out manually and the extracted juice can be transferred into the blender container at the same time.

DE 1084457 B discloses a lid with a funnel-shaped, closable with a stopper, filling opening for Mixflüqeln with a Mix- hold inserted into the filling opening plug used as citrus feet press head, in its lower lateral surface in the region of the filling opening troughs for the having squeezed juice. Even with this device citrus fruits can be pressed out manually when inserted into the lid citrus, the squeezed juice can flow through the gutters between the discharge nozzle and plug into the shaker.

From WO 2013 079 444 A1 an attachment for a bowl of a food processor is known, which is equipped with an electric drive for driving a tool of the food processor. The attachment includes an opening for filling food into the bowl, allowing food to be fed through the attachment into the bowl at any time during operation, upon which the attachment is mounted. A food processing tool can be part of an attachment, such as a citrus press, which is placed on the attachment during operation. Squeezed juice can reach the bowl through the opening of the attachment. Alternatively or additionally, a tool may also be mounted below the attachment. Such a citrus press is also known from US 6070519 A.

Presentation of the invention

The invention is therefore based on the object, a mixer of the type described above, which has a lid which is tightly closed if necessary even with a conventional plug, with simple means such that thus an advantageous squeezing citrus fruits is possible, in particular, a premature laying of the retaining screen should be avoided. The invention achieves this object by virtue of the fact that the citrus fruit press head is assigned a pulp and cores away from the passage opening retaining screen which is rotatably connected to the citrus fruit press and that on the lid a radial radially on a shoulder on the lid surface of the lid secured, splash guard is attached.

According to the invention, the citrus fruit press head and the retention screen are driven in rotation together via the rotor, so that no separate rotary drive must be provided for the citrus fruit press head and the retention screen connected therewith in a rotationally fixed manner. The fact that the retaining screen is also rotationally driven, an automatic cleaning of the retaining screen is ensured during operation of the food processor, as on the retaining sieve resting pulp centrifugal force is transported radially outward to the splash guard funnel. The retention strainer keeps pulp and seeds away from the passage opening. In order to avoid canning of fruit juice and meat in the radial direction when squeezing citrus fruits, the lid is associated with a citrus fruit press head radially comprehensive, radially secured splash guard funnel. The radial securing takes over a provided on the cover surface circumferential shoulder. On the other hand, a shoulder protruding downwards from the lid ensures that the lid is secured to the blender container.

The citrus press head and the retaining screen are in particular rotationally connected to the rotor by means of the shaft via a dog clutch, wherein claws of the dog clutch are in engagement with the rotor, mixing blades associated with the rotor. For this purpose, the citrus press head is extended beyond the citrus fruit press head bottom with a shaft, which shaft is preferably releasably connected to the citrus press head and the retaining screen. The shaft engages on the rotor by means of a rotational drive.

In order to be able to ensure proper guidance of the shaft in the region of the citrus fruit press head, the shaft is provided in the vicinity of the citrus fruit press head with a bearing in the form of a bearing plug. This bearing plug is inserted into the lid of the blender jar and freely rotates the shaft. This storage plug may be a simple plastic plain bearing, a ball bearing or any other bearing or have.

In order to be able to connect the shaft to the rotor as simply as possible and safely in a rotationally fixed manner, the coupling is a claw coupling, the claws of which are in engagement with the rotor, mixing blades belonging to the rotor. Stand the claws with the rotor while secured by a catch in the direction of the axis of rotation engaged, so unwanted removal or discard the shaft from the rotor in the press operation is reliably avoided, as this may have a destruction of the shaft result.

Leakage of liquid from the food processor can be avoided if the splash guard at least ends converging away from the cover conical. Citrus fruit press, retaining screen and possibly the shaft can be integrally formed. For a better cleaning and storage, it may be advantageous if the citrus fruit press, the retaining screen and optionally the shaft are rotatably connected to each other via a coupling. Thus, citrus press head and retention screen can be placed on a shaft journal, which rotatably receives citrus press head and retaining screen.

In order to have a lid, which can also be tightly closed with a conventional stopper if required, the storage stopper can have at least one passage opening, which is optionally associated with a retaining screen. The citrus fruit juice can then flow through this passage in the storage plug from the top of the lid into the blender container. Particularly simple and elegant construction conditions result when the bearing plug has at least one recessed from its outer periphery to the axis of rotation, the passage opening releasing indentation. This construction is particularly easy to clean when removed from the cover bearing plug.
