Tiltable food processor

description

Background of the invention

The present invention relates to a food processor, in particular for the preparation of food in the kitchen, according to the preamble of claim 1.

State of the art

From the prior art, a known under the name "Le Chef" kitchen machine is known, which has a receiving point for attaching a mixing bowl. The receiving point is located on the top of the housing of a drive unit for rotationally driving a tool in the mixing bowl. The drive unit comprises a motor arranged in the housing, which drives a shaft which protrudes upward from the receiving location. The mixing bowl has at its bottom a hollow pipe with an opening through which the shaft protrudes into the mixing bowl. A tool mounted on the shaft is rotated by rotating the shaft in the mixing bowl. The receiving location is inclined relative to the bottom surface of the known food processor by about 15 °, so that the mixing bowl and the shaft are inclined by this angle. The machine can be used both for stirring and for mixing.

The prior art also discloses a food processor sold under the name "Moulinex Master Chef Delicio". The machine has a

Drive unit and a receiving point arranged adjacent thereto for a mixing bowl.

The receiving point runs parallel to the base. From the center of the receiving location, a shaft driven by the drive unit projects vertically upwards. The

Mixing bowl has on its underside a hollow pipe with an opening through which the shaft protrudes into the mixing bowl to a arranged in the mixing bowl

Rotate the tool in rotation. When the food processor is placed on a horizontal base for use, the symmetry axis of the Mixing bowl and the axis of rotation of the tool vertically. The known food processor can be used both for stirring and for mixing. For mixing, a special mixing insert is provided, which is inserted between the mixing bowl wall and the tool in the bowl to improve the mixing result.

The invention is based task

The invention has for its object to provide an improved food processor, which can be used both for stirring and for mixing with good results, which is easy to handle and which can be produced inexpensively.

Inventive solution

To solve the problem, the present invention teaches a food processor with the features of claim 1.

Experiments have shown that a food processor with a mixing bowl with good results can also be operated as a mixer when the mixing bowl is tilted. On the other hand, tilting of the mixing bowl during stirring can adversely affect the stirring result. The tilting device according to the invention, the food processor can be operated with either inclined or not inclined mixing bowl, depending on which task is currently pending.

By the invention can be advantageously achieved that the machine delivers good results both during stirring and during mixing.

Detailed description of an embodiment

The kitchen appliance 1 shown in FIG. 1 has a drive unit 2 accommodated in its housing and a receiving station 3 arranged on the housing for a mixing bowl 4. The drive unit comprises an electric motor, not shown, which is connected via a transmission with a shaft 6, not shown, which is made the receiving point protrudes vertically to drive a tool 9 in the mixing bowl 4 rotating. The food processor 1 is placed on the horizontal footprint 5 in its stirring position, in which the receiving point 3 is aligned horizontally parallel to the footprint 5 and the axis of symmetry of the substantially rotationally symmetrical mixing bowl 4 is perpendicular. The mixing bowl 4 is approximately cylindrical, but tapers slightly downwards.

Fig. 2 shows the food processor 1 in its mixing position. In this position, the entire machine 1, including the drive unit and shaft, is inclined at an angle of about 35 ° relative to its stirring position. The mixing bowl is thereby also inclined by the same angle. The inclination is realized by a wedge, not shown in the figure as a spacer element which can be pushed between the food processor 1 and 5 footprint and is fixed by projections on the wedge top and corresponding recesses in the bottom of the food processor 1 to the latter.

Fig. 3 shows a schematic elevational view of the receiving point 3 with attached to her mixing bowl 4. From the receiving position 3, the shaft 6 of the drive unit 2 projects upwards into a hollow socket 7 in the bottom 8 of the mixing bowl 4. The hollow pipe 7 is provided at its upper end with an opening, not shown, through which the shaft 6 projects into the interior of the mixing bowl 4. It drives a tool 9, as indicated by the arrow 10, rotating. The tool 9 is equipped in its lower part with two knives 1 1 and 12, whose leading edges in the direction of rotation are formed as cutting edges. Knife 1 rotates about 1 cm, knife 12 about 3 cm above the bottom of the bowl 8.

In the stirring position shown in Fig. 3, the receiving position 3 is substantially aligned horizontally, the axis of symmetry 13 of the mixing bowl 4 is substantially perpendicular and also the shaft 6 and the predetermined axis of rotation of the tool 9 are perpendicular. The mixing bowl 4 is preferably so far filled with stirring material 14 during operation that both blades 1 1, 12 rotate in the material to be stirred 14. In the stirring position, the stirrer is operated at a speed of 2,000 rpm.

4 shows the operation of the food processor 1 in its mixing position. In this case, the receiving point 3 and with it the mixing bowl 4 and the tool 9 at an angle inclined by about 35 °. The mix 15 accumulates in this position on one side of the mixing bowl 4. The blades 1 1 and 12 occur at each revolution once in the mix 15 and again out of it.

By the invention, an easy-to-design and easy-to-use food processor can be created, which provides good results both during stirring and during mixing.

The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in any combination for the realization of the invention in its various forms.
