The technical field

The present invention relates to a food processor with a site of articulation and a lid for closing section of the articulation according to the restrictive part of paragraph 1 of the claims. In addition, it relates to a method of opening the cover section of the articulation according to the restrictive part of paragraph 15 of the claims. Finally, it relates to a method for closing the cover section of the articulation according to the restrictive part of paragraph 16 of the claims.

The level of technology

In the modern prior art food processor MK Bosch und Siemens Hausgeräte GmbH, with two sections of the coupling for connecting the processors. In each area of the joint of casing is driven from the engine shaft, is used for the rotational drive of the tool handling device. One of the areas of articulation in the case when not in use, can be closed easily removable and easy slip-on style cover. This is to prevent injury to the user rotating shaft or the tool during the operation of a food processor. In addition, with the same purpose, has a security mechanism that interrupts power to the motor when at the site of articulation there is no handling device or cover.

Furthermore, from European patent for the Cai ER 1535558 A1 is known a food processor with the two parts of the coupling to the processing device, one of which may be closed by a cover. Cover to the housing on the axis of rotation can be rotated, i.e. it can be rotated from a closed position in which it closes the area of the junction, in the open position, in which the area of articulation can join processing device. On the underside of the lid has a tab with a locking element, which when closed, the lid fits into a recess in the housing. There he is captured by the latch for holding the cover in closed position. The latch is connected to the release button that can be operated from the outside. When you click unlock the locking element under the action of elastic return element retainer is released, and the cover under the influence of another elastic return element, located near the axis of rotation, independently rotated to the open position.

The lack of a food processor MK Bosch und Siemens Hausgeräte GmbH can be considered that the cover can be lost, because to open it is removed from a food processor. This may cause the harvester will be continuously operated connected with this part of the joint processing device when the processing device is not used at all. The consequence of this may be, among other things, on yennoe energy consumption, more rapid wear and a greater level of generated noise. In a food processor, known from EP 1535558 A1, loss cover is prevented due to the fact that the cover is attached to the body. However, the locking mechanism opening and closing the cover before attaching the processing device or after its removal, too expensive. This may negatively affect the cost of production of the harvester.
