The technical field

The invention relates to a juice extractor according restrictive part of paragraph 1 of the claims.

The level of technology

From patent document EP 423 457 B1 famous juicer for citrus fruits, squeezing cone which rotates the drive shaft from the motor. Release the cone around the perimeter is surrounded by a sieve with a capacity of holes. Between the cone and the sieve is provided an annular gap. The circumference of the sieve can be uniformly distributed cavities, which may, for example, to enter the tabs on the cone. The cross-section of the annular gap can be adjusted. To change the cross-section of the drying cone is adjustable in height relative to the sieve. This changes the position of the side surface of squeezing cone relative to the sieve in the area of the annular gap. The disadvantage is the small range of variation of the cross section, since the height of squeezing cone design considerations cannot be changed arbitrarily. In particular, the cross-sectional area of the gap surrounding the release cone is too small.

Disclosure of inventions

The objective of the invention is to improve the positioning of the first surface of the sieve relative to the second surface. In particular, it is necessary to prevent inadvertent changes to the user-selected settings.

This task according to the invention is solved in that to limit the number of possible fixed relative positions of the first and second surfaces of the sieves on the first surface of the sieve is provided a latch with a locking tooth which engages with the response element (hereinafter referred to as contrectation) in the form of several wedge-shaped teeth on the second surface of the sieve.

Thanks to this solution you can create a simple and inexpensive structure for positioning the first surface of the sieve relative to the second surface with a limited number of possible positions.

On one surface si is and can be provided for carrying or through holes, the corresponding maximum throughput surface extractor. Preferably below the surface of the screen may be provided to the other surface, is made in such a way that by changing the position of this second surface is a capacity or through holes of the first surface of the sieve can be opened and closed, in particular, due to the overlap of the access holes of the first sieve. In one preferred embodiment, bandwidth or through holes of the second surface of the screens have the same size, same shape and same location as the access openings of the first surface of the sieve.

In a preferred embodiment of the invention the first surface of the screen can be rotated relative to the second surface of the sieve around the axis of squeezing cone. Located on both surfaces of the sieve throughput openings are preferably in the form of stellate radially elongated slots in the surface of the sieve. If the surface of the sieve can be rotated relative to each other, by rotating both screens, you can change the size of the opening holes of the sieve at a very small angle, starting from the fully closed position to the position with the maximum of the open holes. For this, the first surface of the sieve is installed on the second surface of the sieve in a rotating bearing. Turntable with which is preferably of an annular flange, provided on the first surface of the sieve, which fits over the cylindrical neck support provided on the second surface of the sieve. Thus, the first surface of the sieve is mounted on the second surface of the sieve by simply donning along the axis.

For fixing the first surface of the sieve on the second surface in the axial direction in the bearing neck may be provided, at least one radial protrusion. After the first surface of the screen will be mounted on the second surface of the sieve by simply donning along the axis, no special axial fixation of the first surface of the sieve on the second surface is not required. The annular flange of the first surface of the sieve is placed behind the radial protrusion for supporting the neck of the second surface of the sieve and fixed in the axial direction and can be rotated around the axis. Separate mounting operation for the axial fixation of the first surface of the sieve on the second surface is not required, reducing the complexity of manufacturing juicers in General.

In one preferred version of the second surface of the sieve is provided at least one stop that can be moved to change the relative position of the first and second surfaces of the sieves between the two contrmporary under the military on the first surface of the sieve. Thus, for a user defined limits, in which the first surface of the screen can be rotated relative to the second surface of the sieve, in particular at the maximum angle.

To limit the number of possible mutual positions of the first and second surfaces of the sieves on the first surface of the sieve may be a latch, tazapsidis for a response element on the second surface of the sieve. Thus the user is provided with a countable number of possible positions on the screen. It also prevents the spontaneous change of the specified position.

The connection of the latch and contractor can be implemented using a locking prong, mating with a toothed profile. The locking tooth and tooth profile can be in particular formed at the same time with the corresponding surfaces of the sieves of the plastic molding under pressure. The locking teeth and the toothed profile on the surfaces of the screens shown in the example of execution, can be swapped.

Preferably, the first surface of the sieve was provided in the area of capture, holding that it could change its position relative to the second surface of the sieve. The site of capture may have a side wall resting on the edge of the receiver. Preferably at the site of capture predusmatriva what is the scope of control with structured surface not to loose the hand. At the site of capture can be in particular visual and/or tactile markings indicating the direction of rotation. The site management can be molded three lenticular projection or elevation of various sizes. Different diameters and/or different height elevations are used to indicate the direction of rotation in which the cross section of the holes of the surfaces of the sieve increases or decreases. If part of the grip to rotate the first surface of the sieve in the direction of large lenticular elevations, cross-section of the holes in the surfaces of the sieve will increase. If part of the grip to rotate the first surface of the sieve in the direction of smaller lenticular elevations, cross-section of the holes in the surfaces of the sieve will be reduced. Lenticular elevation can be seen not only through the sense of vision, but because they are on land management at different heights or have different diameters, they can be felt, and not looking.
